DETAILED DESCRIPTION

0039Different methods for closing or tightening shoes or boots and other flexible or semi-rigid panels have evolved over the years. Conventional laces whether led through metal eyelets, webbing loops, or low friction guides, have stood the test of time and remain popular. Mechanical systems using rotary dials, serrated grip surfaces and other designs may provide alternatives to knot-secured laces. Hook and loop engagements as well as elastic straps may also serve well in some applications. Currently available designs though present certain drawbacks. For example, conventional laces require the tying of a knot to secure the tightened adjustment, which obligates the user to untie the knot before any secondary adjustment can be made, unless or until the knot loosens of its own accord, requiring retying. Conventional lace systems are also limited to the use of relatively large diameter laces that are comfortable to grip by hand, the opposite desired characteristics for low-profile, efficient and effective closure. Rotary dials and other mechanical systems eliminate the knot problem and can make use of small diameter laces, but tend to be expensive to manufacture, to the point that they can represent up to 50% of the cost of a given pair of footwear. Some knotless fixation systems self-store excess lace while others require excess lace to be gathered and placed into a pocket on the boot, which is an inconvenient and inelegant solution.

0040Given the harsh environment of daily use, often in climate extremes, mechanical system latching performance may also be problematic, often when a secure closure is needed most. Hook and loop and elastic systems also suffer performance loss in wet and/or freezing conditions, while being limited in the adjustment range and security of their closure. In addition to fixation issues, many lace systems suffer from excessive friction which can prevent the lace from exerting sufficient closure force in the area farthest from the point where tension is applied. This friction can have many causes including the lace material characteristic, the lace turning guides, the sliding of the lace over high friction surfaces, and also the points at which opposing laces cross over one another. In this aspect of lace function, the dilemma becomes one in which the more tension applied to tighten the closure, the more frictional force is created and the more difficult it becomes to obtain the desired closure. The present disclosure addresses these and other issues by providing a non-complex, inexpensive, non-mechanical, low-friction, knotless closure system with self-storage of excess lace.

0041For instance, referring now collectively to <figref idref="DRAWINGS">FIGS. 1-8</figref>, first lace fixation assembly <b>100</b> and first lace fixation system <b>102</b> are shown in accordance with the present disclosure. In general, first assembly <b>100</b> includes first plate <b>104</b>, second plate <b>106</b>, tensioning component <b>108</b>, and fastener <b>110</b>. <figref idref="DRAWINGS">FIG. 1</figref> for example illustrates these respective components of first assembly <b>100</b> in an assembled configuration. First system <b>102</b> includes first assembly <b>100</b>, guide members <b>112</b>, and tension member <b>114</b>. <figref idref="DRAWINGS">FIG. 8A</figref> for example shows these respective components of first system <b>102</b> in an assembled configuration. In the example embodiment, tension member <b>114</b> is laced through first plate <b>104</b> of first assembly <b>100</b> via arcuate slots <b>116</b> that guide ends of tension member <b>114</b> from entry apertures <b>118</b> to exit aperture <b>120</b>. <figref idref="DRAWINGS">FIG. 2</figref> for example illustrates entry apertures <b>118</b> and exit aperture <b>120</b>, and <figref idref="DRAWINGS">FIG. 3</figref> for example illustrates arcuate slots <b>116</b>. Tension member <b>114</b> is further laced through guide members <b>112</b> via opposing grooves <b>122</b> so that tension member <b>114</b> does not overlap onto itself when laced thereto. Both first assembly <b>100</b>, at least in part, and guide members <b>112</b> are coupled to front panel <b>124</b> of boot <b>126</b>, and tensioning end <b>128</b> of tension member <b>114</b> is coupled to tensioning component <b>108</b> at notch <b>130</b> of tensioning component <b>108</b>. <figref idref="DRAWINGS">FIGS. 8A-B</figref> for example illustrate coupling of first assembly <b>100</b> and guide members <b>112</b> to boot <b>126</b> as well as tension member <b>114</b> to tensioning component <b>108</b>.

0042In practice, tightening of boot <b>126</b> is performed or perfected by application of pulling force to tensioning component <b>108</b>, forcing first side panel <b>132</b> and second side panel <b>134</b> of boot <b>126</b> together. While maintaining pulling force, tensioning component <b>108</b> is used to wrap tension member <b>114</b> into channel or groove <b>136</b> that is formed between first plate <b>104</b> and second plate <b>106</b>. <figref idref="DRAWINGS">FIG. 5</figref> for example illustrates groove <b>136</b> formed between first plate <b>104</b> and second plate <b>106</b>. Here, initial wrapping of tension member <b>114</b> into groove <b>136</b> forces tension member <b>114</b> into friction gap <b>138</b> that has surfaces along the length of which imparts force on tension member <b>114</b> when positioned thereto so that tension is generally maintained on tension member <b>114</b> when pulling force is removed, as discussed further below. Further wrapping of tension member <b>114</b> into groove <b>136</b> forces portions of tension member <b>114</b> into storage gap <b>140</b>. Storage gap <b>140</b> within groove <b>136</b> is therefore generally wider than friction gap <b>138</b> as storage gap <b>140</b> serves a different purpose than friction gap <b>138</b> in that it is used to store excess length of tension member <b>114</b>. Tension member <b>114</b> as wrapped onto itself though within both friction gap <b>138</b> and storage gap <b>140</b> imparts force on itself when positioned thereto, so that tension is generally maintained on tension member <b>114</b> when pulling force is removed.

0043Wrapping of tension member <b>114</b> into groove <b>136</b> proceeds until length of tension member <b>114</b> protruding from exit aperture <b>120</b> is substantially wound into groove <b>136</b>. Tensioning component <b>108</b> is then generally snap-coupled onto first assembly <b>100</b> at groove <b>136</b>. Tensioning component <b>108</b> may be decoupled from first assembly <b>100</b> by application of leverage similar to that applied when opening a bottle having a cap, and may be used to unwind tension member <b>114</b> thereby loosening first side panel <b>132</b> and second side panel <b>134</b> of boot <b>126</b>. First side panel <b>132</b> and/or second side panel <b>134</b> may then be opened to allow exit, or tension reapplied to tension member <b>114</b> as desired. Such an implementation may be beneficial or advantageous in many respects. For example, knotting of tension member <b>114</b> is not required, excess length of tension member <b>114</b> is stored to first assembly <b>100</b> without additional steps, and through the use of tensioning component <b>108</b>, there is no need for a user to physically touch tension member <b>114</b>. Still other benefits and/or advantages are possible as well.

0044Referring now specifically to <figref idref="DRAWINGS">FIGS. 1-6</figref>, first lace fixation assembly <b>100</b> is shown in accordance with the present disclosure. As mentioned above, first assembly <b>100</b> includes first plate <b>104</b>, second plate <b>106</b>, tensioning component <b>108</b>, and fastener <b>110</b>. When assembled, axle- or post-like keyed portion <b>142</b> formed on protrusion <b>144</b> of first plate <b>104</b>, as shown for example in <figref idref="DRAWINGS">FIG. 2</figref>, is positioned to complementary recess <b>146</b> of second plate <b>106</b>, as shown for example in <figref idref="DRAWINGS">FIG. 4</figref>. Additionally, fastener <b>110</b> is positioned to both second plate aperture <b>148</b> that is adjacent to recess <b>146</b> and first plate aperture <b>150</b> that is formed within keyed portion <b>142</b> to secure first plate <b>104</b> with second plate <b>106</b>. In the example embodiment, keyed portion <b>142</b> and recess <b>146</b> are star-shaped in cross-section. Other embodiments are however possible, and shape of keyed portion <b>142</b> and recess <b>146</b> may be implementation-specific. Further, as mentioned above, tensioning component <b>108</b> is generally snap-fit coupleable to groove <b>136</b> that is formed between first plate <b>104</b> and second plate <b>106</b>. Rotational movement of tensioning component <b>108</b> is limited or restricted when positioned to groove <b>136</b> by interlock of bumps or ridges <b>152</b> formed on both second plate <b>106</b> and tensioning component <b>108</b>, illustrated for example at <figref idref="DRAWINGS">FIG. 4</figref> and at <figref idref="DRAWINGS">FIG. 6</figref>.

0045Friction gap <b>138</b> within groove <b>136</b> is defined by first ridged flutes <b>154</b> that extend in a spoke pattern from keyed portion <b>142</b> of first plate <b>104</b>, and second ridged flutes <b>156</b> that extend in the spoke pattern from recess <b>146</b> of second plate <b>106</b>. <figref idref="DRAWINGS">FIG. 2</figref> for example illustrates first ridged flutes <b>154</b>, and <figref idref="DRAWINGS">FIG. 4</figref> for example illustrates second ridged flutes <b>156</b>. It is contemplated that more or fewer ridged flutes may be utilized in any pattern as desired, and further number and shape of first ridged flutes <b>154</b> and second ridged flutes <b>156</b> may be implementation-specific. In the example embodiment, when first plate <b>104</b> is coupled with second plate <b>106</b>, first ridged flutes <b>154</b> and second ridged flutes <b>156</b> are rotationally offset from each other so as to form a path for tension member <b>114</b> similar to that formed by an interdigitated comb structure. In this instance, however, fingers of the comb structure are interdigitally arranged along a circle. In this manner, first ridged flutes <b>154</b> and second ridged flutes <b>156</b> are configured and arranged to impart force on tension member <b>114</b> when tension member <b>114</b> is positioned to friction gap <b>138</b> within groove <b>136</b>, so that tension is generally maintained on tension member <b>114</b> when pulling force is removed.

0046Referring now specifically to <figref idref="DRAWINGS">FIGS. 7A-C</figref>, a particular one of guide members <b>112</b> is shown in accordance with the present disclosure. As mentioned above, tension member <b>114</b> is laced through guide members <b>112</b> via opposing grooves <b>122</b> so that tension member <b>114</b> does not overlap onto itself. In general, grooves <b>122</b> positioned on each side of mounting aperture <b>158</b> provide a curved low-friction pathway for tension member <b>114</b> as it interfaces with panels <b>124</b>, <b>132</b>, and <b>134</b> of boot <b>126</b>, similar to arcuate slots <b>116</b> of first plate <b>104</b> that provide a low-friction pathway for tension member <b>114</b> from entry apertures <b>118</b> to exit aperture <b>120</b>. Whereas a typical lacing pattern may route laces back and forth between opposing panels, with laces crossing each other at various points along the center line of a particular panel, guide members <b>112</b> eliminate lace crossing and resulting friction that which may impede closure. It is contemplated that any number of guide members <b>112</b> may be employed to realize desired closure characteristics while maintaining the lowest possible lace system friction.

0047In the present example, with guide members <b>112</b> attached to center portion of front panel <b>124</b>, tension member <b>114</b> is guided from first side panel <b>132</b> through a particular one of guide members <b>112</b>, and back to first side panel <b>132</b>. Similarly, tension member <b>114</b> is guided from second side panel <b>134</b> through a particular one of guide members <b>112</b>, and back to second side panel <b>134</b>. Tension member <b>114</b> thus does not overlap onto itself and does not bind, chafe, or create excess friction. It is contemplated that body <b>160</b> of guide members <b>112</b> may be curved to generally match the shape of front panel <b>124</b> or other intermediate panel onto which they are coupled. Further, profile or thickness <b>162</b> of guide members <b>112</b> may be defined such that tension member <b>114</b> is raised above a surface of an intermediate panel to further reduce friction. Various methods may be employed to attach guide members <b>112</b> to front panel <b>124</b>, such as in a manner that allows guide members <b>112</b> to self-align under loads presented by tension member <b>114</b>. Further, in order to facilitate injection molding with minimal tooling complexity, in one embodiment the bearing surface of the guide members <b>112</b> may be formed by alternating grooves in top and bottom surfaces. This arrangement may sufficiently capture tension member <b>114</b>, keeping tension member <b>114</b> bearing upon the desired radius surface, while not requiring any sliding elements in the injection mold.

0048Referring now to <figref idref="DRAWINGS">FIG. 9</figref>, another lace fixation system <b>902</b> is shown in accordance with the present disclosure. System <b>902</b> is similar to first lace fixation system <b>102</b> as described above in many respects. For example, system <b>902</b> includes first lace fixation assembly <b>100</b> of at least <figref idref="DRAWINGS">FIG. 1</figref> coupled to front panel <b>904</b> of boot <b>906</b>. In the example embodiment, however, tension member <b>908</b> is laced through guide members <b>910</b> so as to overlap or cross itself. Guide members <b>910</b> in <figref idref="DRAWINGS">FIG. 9</figref> are webbing or fabric strips that are sewn or otherwise coupled to panels of the article. The webbing or fabric strips <b>910</b> include loops through which the tension member <b>908</b> is inserted. The webbing or fabric strips <b>910</b> may be angled or directed to guide the tension member <b>908</b> about the article as desired. In practice though, tightening of boot <b>906</b> using first assembly <b>100</b> may be performed in a manner similar to that described above. Further, <figref idref="DRAWINGS">FIG. 9</figref> demonstrates flexibility of first assembly <b>100</b> in that tensioning component <b>108</b> may be coupled to groove <b>136</b> (e.g., see <figref idref="DRAWINGS">FIG. 5</figref>) that is formed between first plate <b>104</b> and second plate <b>106</b> without orientation-specific keying. In other words, tensioning component <b>108</b> may be coupled to groove <b>136</b> in any particular orientation. For example, <figref idref="DRAWINGS">FIG. 8C</figref> illustrates tensioning component <b>108</b> positioned to groove <b>136</b> so that notch <b>130</b> is orientated towards guide members <b>112</b>. In contrast, <figref idref="DRAWINGS">FIG. 9</figref> illustrates tensioning component <b>108</b> positioned to groove <b>136</b> so that notch <b>130</b> is orientated away from guide members <b>910</b>.

0049Referring now to <figref idref="DRAWINGS">FIGS. 10A-16B</figref>, second lace fixation assembly <b>1000</b> and second lace fixation system <b>1002</b> are shown in accordance with the present disclosure. In general, second assembly <b>1000</b> includes plate <b>1004</b> and tensioning component <b>1006</b>. <figref idref="DRAWINGS">FIG. 10B</figref> for example illustrates these respective components of second assembly <b>1000</b> in an assembled configuration. Second system <b>1002</b> includes second assembly <b>1000</b>, guide members <b>1008</b>, and tension member <b>1010</b>. <figref idref="DRAWINGS">FIG. 15</figref> for example illustrates these respective components of second system <b>1002</b> in an assembled configuration. In the example embodiment, tension member <b>1010</b> is laced through plate <b>1004</b> of second assembly <b>1000</b> via plate apertures <b>1011</b> that guide tension member <b>1010</b> through plate <b>1004</b>, and further is laced through guide members <b>1008</b> so that tension member <b>1010</b> overlaps onto itself. <figref idref="DRAWINGS">FIG. 12C</figref> for example illustrates plate apertures <b>1011</b>, and <figref idref="DRAWINGS">FIG. 15</figref> and <figref idref="DRAWINGS">FIG. 16A</figref> for example illustrate lacing of tension member <b>1010</b> through guide members <b>1008</b> that are coupled to boot <b>1014</b>, and lacing of tension member <b>1010</b> through plate <b>1004</b>, respectively. Other embodiments though are possible. For example, it is contemplated that guide members <b>112</b> as discussed above may be used in place of guide members <b>1008</b>.

0050Both second assembly <b>1000</b>, at least in part, and guide members <b>1008</b> are coupled to front panel <b>1012</b> of boot <b>1014</b>, and tensioning end <b>1016</b> of tension member <b>1010</b> is coupled to tensioning component <b>1006</b> at component apertures <b>1018</b>. <figref idref="DRAWINGS">FIGS. 11A-B</figref> for example illustrate component apertures <b>1018</b> of tensioning component <b>1006</b>, and <figref idref="DRAWINGS">FIG. 16A</figref> for example illustrates tensioning end <b>1016</b> of tension member <b>1010</b> coupled to tensioning component <b>1006</b>. In the example embodiment, component apertures <b>1018</b> flare open into elongated slots on bottom side <b>1005</b> of tensioning component <b>1006</b> to gently guide tension member <b>1010</b> therethrough, and plate <b>1004</b> includes primary surface <b>1007</b> that may be curved to at least partially conform to shape of panel <b>1012</b> of boot <b>1014</b>, similar to first plate <b>104</b> of first assembly <b>100</b> shown at least in <figref idref="DRAWINGS">FIG. 1</figref>.

0051In practice, tightening of boot <b>1014</b> is performed or perfected by application of pulling force to tensioning component <b>1006</b>, forcing first side panel <b>1020</b> and second side panel <b>1022</b> of boot <b>1014</b> together. While maintaining pulling force, tensioning component <b>1006</b> is used to wrap tension member <b>1010</b> into channel or groove <b>1024</b> formed by plate <b>1004</b>. <figref idref="DRAWINGS">FIG. 10B</figref> for example illustrates groove <b>1024</b> formed by plate <b>1004</b>. Wrapping of tension member <b>1010</b> tightly onto itself within groove <b>1024</b> fixes tension member <b>1010</b> in place, so that tension is generally maintained on tension member <b>1010</b> when pulling force is removed. Wrapping of tension member <b>1010</b> into groove <b>1024</b> proceeds until length of tension member <b>1010</b> protruding from component apertures <b>1018</b> is substantially wrapped into groove <b>1024</b>. Tensioning component <b>1006</b> is then snap-coupled onto flange <b>1026</b> of plate <b>1004</b> so that locking surface <b>1028</b> of at least one flexible tab <b>1030</b> of tensioning component <b>1006</b> engages with locking surface <b>1032</b> of flange <b>1026</b> adjacent to groove <b>1024</b>. <figref idref="DRAWINGS">FIG. 14</figref> in a particular instance illustrates tensioning component <b>1006</b> snap-coupled onto flange <b>1026</b> of plate <b>1004</b>. In the example embodiment, tensioning component <b>1006</b> may subsequently be decoupled from plate <b>1004</b> by application of leverage to tensioning component <b>1006</b> similar to that of opening certain types of aspirin containers for example, and may be used to unwind tension member <b>1010</b>, thereby releasing force imparted on first side panel <b>1020</b> and second side panel <b>1022</b> of boot <b>1014</b>. First side panels <b>1020</b> and/or second side panel <b>1022</b> may then be opened to allow exit, or tension reapplied to tension member <b>1010</b> as desired. Such an implementation may be beneficial or advantageous in many respects, including at least those discusses above in connection with first assembly <b>100</b>.

0052Further, referring now specifically to <figref idref="DRAWINGS">FIGS. 16A-B</figref>, flexibility of second assembly <b>1000</b> is demonstrated in that tension member <b>1010</b> may be laced through plate <b>1004</b> of second assembly <b>1000</b> in a particular direction as desired. For example, <figref idref="DRAWINGS">FIG. 16A</figref> illustrates tension member <b>1010</b> laced through plate <b>1004</b> of second assembly <b>1000</b> in a direction extending away from front end of shoe <b>1014</b>, so that tightening of shoe <b>1014</b> is perfected by application of pulling force generally in direction A. In contrast, <figref idref="DRAWINGS">FIG. 16B</figref> illustrates tension member <b>1010</b> laced through plate <b>1004</b> of second assembly <b>1000</b> in a direction extending towards front end of boot <b>1014</b>, so that tightening of boot is perfected by application of pulling force generally in direction B.

0053Referring now specifically to <figref idref="DRAWINGS">FIGS. 11-14</figref>, second lace fixation assembly <b>1000</b> is shown in accordance with the present disclosure. <figref idref="DRAWINGS">FIGS. 12A-C</figref> in particular show second assembly <b>1000</b> in varying dimension, generally increasing in size from <figref idref="DRAWINGS">FIG. 12A</figref> proceeding in order to <figref idref="DRAWINGS">FIG. 12C</figref>. As mentioned above, second assembly <b>1000</b> includes plate <b>1004</b> and tensioning component <b>1006</b>. When assembled, keyed aperture <b>1034</b> formed within flange <b>1026</b> of plate <b>1004</b> is positioned to complementary post <b>1036</b> of tensioning component <b>1006</b>. <figref idref="DRAWINGS">FIG. 11A</figref> and <figref idref="DRAWINGS">FIG. 11B</figref> for example illustrate keyed aperture <b>1034</b> formed within flange <b>1026</b> of plate <b>1004</b>, and post <b>1036</b> of tensioning component <b>1006</b>. In the example embodiment, keyed aperture <b>1034</b> and post <b>1036</b> are peripherally notched. Other embodiments are however possible. Tensioning component <b>1006</b> is snap-fit coupleable to keyed aperture <b>1034</b> formed within flange <b>1026</b> of plate <b>1004</b> by at least one flexible tab <b>1030</b> of tensioning component <b>1006</b> that has locking surface <b>1028</b> that engages with locking surface <b>1032</b> of flange <b>1026</b> adjacent groove <b>1024</b>. <figref idref="DRAWINGS">FIG. 14</figref> for example illustrates flexible tab <b>1030</b> of tensioning component <b>1006</b> that has locking surface <b>1028</b> that engages with locking surface <b>1032</b> of flange <b>1026</b> adjacent to groove <b>1024</b>. In the example embodiment, rotational movement of tensioning component <b>1006</b> when coupled to plate <b>1004</b> is limited or restricted because post <b>1036</b> is rigidly fixed to plate <b>1004</b> at mounting surface <b>1038</b>.

0054Referring now to <figref idref="DRAWINGS">FIG. 17</figref>, still another lace fixation system <b>1702</b> is shown in accordance with the present disclosure. System <b>1702</b> is similar to second lace fixation system <b>1002</b> as described above in many aspects. For example, system <b>1702</b> includes second lace fixation assembly <b>1000</b> of at least <figref idref="DRAWINGS">FIG. 10</figref> coupled to panel <b>1704</b> of item <b>1706</b>. In this example, however, second assembly <b>1000</b> is not coupled to a central panel of item <b>1706</b>, and further tension member <b>1708</b> is alternately laced through guide members <b>1710</b> terminating at end <b>1712</b>. In practice though, tightening of item <b>1706</b> using second assembly <b>1000</b> may be performed in a manner similar to that described above. Further, <figref idref="DRAWINGS">FIG. 17</figref> demonstrates flexibility of second assembly <b>1000</b> in that second assembly <b>1000</b> may generally be coupled to a particular item at any location as desired, such as to an eyestay of a shoe as illustrated in <figref idref="DRAWINGS">FIG. 17</figref>. Termination at end <b>1712</b> as shown in <figref idref="DRAWINGS">FIG. 17</figref> may increase the tension imparted to tension member <b>1708</b> as the system is used to close item <b>1706</b>. Still other lace fixation systems embodiments are possible.

0055For example, referring now to <figref idref="DRAWINGS">FIG. 18</figref>, still another lace fixation system <b>1802</b> is shown in accordance with the present disclosure. System <b>1802</b> is similar to second lace fixation system <b>1002</b> as described above in many aspects. For example, system <b>1802</b> includes first instance <b>1000</b>a of second lace fixation assembly <b>1000</b> of at least <figref idref="DRAWINGS">FIG. 10</figref> coupled to first panel <b>1804</b> of item <b>1806</b>. In this example, however, system <b>1802</b> further includes second instance <b>1000</b>b of second lace fixation assembly <b>1000</b> coupled to second panel <b>1808</b> of item <b>1804</b>, and tension member <b>1810</b> is coupled to fixed guide <b>1812</b> positioned to central panel <b>1814</b> of item <b>1806</b>. In some embodiments, first instance <b>1000</b>a of second assembly <b>1000</b> and second instance <b>1000</b>b of second assembly <b>1000</b> may be sized differently, for example as illustrated in <figref idref="DRAWINGS">FIG. 12</figref>. Such an implementation as shown in <figref idref="DRAWINGS">FIG. 18</figref> may be an example of a zone or zonal tightening system, whereby tension imparted on first length <b>1816</b> of tension member <b>1808</b> may be controlled by first instance <b>1000</b>a of second assembly <b>1000</b>, and tension imparted on second length <b>1818</b> of tension member <b>1808</b> may be controlled by second instance <b>1000</b>b of second assembly <b>1000</b>. Tension member <b>1810</b> may be fixedly coupled with fixed guide <b>1812</b> (i.e., the tension member <b>1810</b> may be prevented from sliding through guide <b>1812</b>) to allow zonal tensioning of a proximal and distal portion of item <b>1806</b>. Still other lace fixation system embodiments are possible.

0056For example, referring now to <figref idref="DRAWINGS">FIGS. 19A-E</figref>, still another lace fixation system <b>1902</b> is shown in accordance with the present disclosure. System <b>1902</b> is similar to second lace fixation system <b>1002</b> as described above in many aspects. For example, system <b>1902</b> includes embodiment <b>1000</b>a of second lace fixation assembly <b>1000</b> of at least <figref idref="DRAWINGS">FIG. 10</figref> coupled to panel <b>1904</b> of item <b>1906</b>. In this example, however, system <b>1902</b> includes tension member <b>1908</b> coupled to fixed guide <b>1910</b> positioned to central panel <b>1912</b> of item <b>1906</b>. As shown in the sequence of <figref idref="DRAWINGS">FIGS. 19A-E</figref>, tension member <b>1908</b> may be positioned to guide members <b>1914</b> and fixed guide <b>1910</b> so that tension member <b>1908</b> may be wrapped and coupled to embodiment <b>1000</b>a of second assembly <b>1000</b> in a manner such as described above. In particular, tension member <b>1908</b> may be initially laced to guide member <b>1914</b>a and guide member <b>1914</b>b positioned in a lower portion of the item, and then laced through fixed guide <b>1910</b> as shown in <figref idref="DRAWINGS">FIG. 19C</figref>, such as by inserting tension member <b>1908</b> through a lumen of fixed guide <b>1910</b>. Tensioning component <b>1006</b> may then be pulled in direction X to apply tension to first length <b>1916</b> of tension member <b>1908</b>, thereby pulling the lower portion of side panel <b>1918</b> and side panel <b>1920</b> together. Tension member <b>1908</b> may then be wrapped around a post of fixed guide <b>1910</b> to lock or maintain a tension of first length <b>1916</b> of tension member <b>1908</b> and thereby secure the lower portion in a tightened arrangement. Tension member <b>1908</b> may then be laced to guide member <b>1914</b>c and guide member <b>1914</b>d in an upper portion of the item. Tensioning component <b>1006</b> may then be pulled in direction Y to apply tension to second length <b>1922</b> of tension member <b>1908</b>, thereby pulling the upper portion of side panel <b>1918</b> and side panel <b>1920</b> together. Tension member <b>1908</b> may then be wrapped into channel or groove <b>1024</b> formed by plate <b>1004</b> to lock or maintain a tension of second length <b>1922</b> of tension member <b>1908</b> and thereby secure the upper portion in a tightened arrangement. Such an implementation as shown in <figref idref="DRAWINGS">FIGS. 19A-E</figref> may be an example of a zone or zonal tightening system, whereby tension imparted on first length <b>1916</b> of tension member <b>1908</b> may be controlled or maintained due to coupling of tension member <b>1908</b> to fixed guide <b>1910</b>, and tension imparted on second length <b>1922</b> of tension member <b>1908</b> may be controlled or maintained due to coupling of tension member <b>1908</b> to plate <b>1004</b>. Still many other lace fixation system embodiments are possible.

0057Referring now to <figref idref="DRAWINGS">FIG. 20</figref>, still another lace fixation system <b>2002</b> is shown in accordance with the present disclosure. System <b>2002</b> is similar to both first lace fixation system <b>102</b> and second lace fixation system <b>1002</b> as described above in many respects. For example, system <b>2002</b> includes first lace fixation assembly <b>100</b> of at least <figref idref="DRAWINGS">FIG. 1</figref> coupled to first panel <b>2004</b> of item <b>2006</b>, and also includes second lace fixation assembly <b>1000</b> of at least <figref idref="DRAWINGS">FIG. 10</figref> coupled to second panel <b>2008</b> of item <b>2006</b>. In this example, however, system <b>2002</b> includes first tension member <b>2010</b> coupled to first assembly <b>100</b> in a manner similar to that described above, and also includes second tension member <b>2012</b> coupled to second assembly <b>1000</b> in a manner similar to that described above. Here, second tension member <b>2012</b> is shown partially in phantom line as a portion of second tension member <b>2012</b> is routed generally underneath outer shell <b>2014</b> of item <b>2006</b>, such as through tubing positioned under the upper of a boot. Such an implementation may be another example of a zone or zonal tightening system, whereby tension imparted on first tension member <b>2010</b> may be controlled by first assembly <b>100</b>, and tension imparted on second tension member <b>2012</b> may be controlled by second assembly <b>1000</b>. In the illustrated embodiment, first tension member <b>2010</b> and first assembly <b>100</b> is used to tighten an upper portion of a boot while second tension member <b>2012</b> and second lace fixation assembly <b>1000</b> is used to tighten a lower portion of a boot. Still other lace fixation system embodiments are possible.

0058Referring now to <figref idref="DRAWINGS">FIG. 21</figref>, still another lace fixation system <b>2102</b> is shown in accordance with the present disclosure. System <b>2102</b> is similar to second lace fixation system <b>1002</b> as described above in many respects. For example, system <b>2102</b> includes second lace fixation assembly <b>1000</b> of at least <figref idref="DRAWINGS">FIG. 10</figref> coupled to panel <b>2104</b> of item <b>2006</b>. In this example, however, second assembly <b>1000</b> is not coupled to a central or offset panel of item <b>2106</b>, and instead is coupled to rear portion <b>2108</b> of item <b>2106</b>, such as heel portion of a shoe. Further, tension member <b>2110</b> is laced to second assembly <b>1000</b> at a point furthest possible from guide members <b>2112</b> of item <b>2106</b>, such as by being routed through tubing coupled with and/or positioned under an upper material layer of the shoe. In practice though, tightening of item <b>2106</b> using second assembly <b>1000</b> may be performed in a manner similar to that described above. Further, <figref idref="DRAWINGS">FIG. 21</figref> demonstrates flexibility of second assembly <b>1000</b> in that second assembly <b>1000</b> may generally be coupled to a particular item at any location as desired. Still other lace fixation system embodiments are possible.

0059Referring now to <figref idref="DRAWINGS">FIG. 22</figref>, still another lace fixation system <b>2202</b> is shown in accordance with the present disclosure. System <b>2202</b> is similar to lace fixation system <b>2002</b> of <figref idref="DRAWINGS">FIG. 20</figref> as described above in many respects. In this example, however, system <b>2202</b> exhibits an alternate embodiment of first lace fixation assembly <b>100</b>. In particular, lace fixation assembly <b>2204</b> coupled to first panel <b>2206</b> of item <b>2208</b> includes reel assembly mechanism <b>2210</b> having a knob or dial component <b>2212</b> that is rotatable in a first direction (e.g., clockwise) to wind the tension member <b>2216</b> about a channel or groove of a spool (not shown) positioned under the knob <b>2212</b> and within a housing <b>2214</b> of the reel assembly mechanism <b>2210</b>. The tension member <b>2216</b> is laced and/or positioned around one or more guides of an upper portion of item <b>2208</b> (i.e., boot). The reel assembly mechanism <b>2210</b> is used to tighten the upper portion of item <b>2208</b> by tensioning the tension member <b>2216</b> via reel assembly mechanism <b>2210</b>. In some embodiments, the reel assembly mechanism <b>2210</b> may be rotated in a second direction (i.e., counter-clockwise) to loosen the tension in tension member <b>2216</b> and thereby loosen the upper portion of item <b>2208</b>. In other embodiments, the knob <b>2212</b> may be grasped and moved axially upward to disengage internal components of reel assembly mechanism <b>2210</b> and thereby release the tension on tension member <b>2216</b>. Second assembly <b>1000</b> may be used to tension a lower portion of item <b>2208</b> as described in the embodiment of <figref idref="DRAWINGS">FIG. 20</figref>. Still other lace fixation assembly embodiments are possible.

0060For example, referring now to <figref idref="DRAWINGS">FIGS. 23A-C</figref>, third lace fixation assembly <b>2300</b> is shown in accordance with the present disclosure. In the example embodiment, tension member <b>2302</b> is laced through plate <b>2304</b> of third assembly <b>2300</b> via lumen or passage <b>2306</b> that guides tension member <b>2302</b> through plate <b>2304</b>, and tensioning end <b>2308</b> of tension member <b>2302</b> is coupled to tensioning component <b>2310</b> at component apertures <b>2312</b>. As shown in particular by the sequence of <figref idref="DRAWINGS">FIG. 23C</figref>, tensioning component <b>2310</b> may initially be pulled in direction C so that tension member <b>2302</b> in turn is pulled through passage <b>2306</b>. Tensioning component <b>2310</b> may then be flipped or positioned back over plate <b>2304</b> whereby portions of tension member <b>2302</b> are engaged with ridged friction surfaces <b>2314</b> within channel <b>2316</b> of plate <b>2304</b>. The ridged friction surfaces <b>2314</b> engage with tension member <b>2302</b> to lock or otherwise maintain the tension member <b>2302</b> in a tensioned stated.

0061<figref idref="DRAWINGS">FIG. 23A</figref> and <figref idref="DRAWINGS">FIG. 23B</figref> too for example illustrates portions of tension member <b>2302</b> engaged with ridged friction surfaces <b>2314</b> within channel <b>2316</b> of plate <b>2304</b>. Tensioning component <b>2310</b> may then be pulled in direction D that is generally opposite direction C so that slack of tension member <b>2302</b> is taken up and portions of tension member <b>2302</b> are fully engaged with ridged friction surfaces <b>2314</b> within channel <b>2316</b> to lock or otherwise maintain the tension member <b>2302</b> in the tensioned stated. Tensioning component <b>2310</b> may then be used to wrap tension member <b>2302</b> within second channel <b>2318</b> of plate <b>2304</b> in rotational direction E and then snap-coupled to flange <b>2138</b> of plate <b>2304</b> in a manner similar to that described above in connection with tensioning component <b>1006</b>. Second channel <b>2318</b> may be separated from channel <b>2316</b> via a flange or other partition member. In the example embodiment, plate <b>2304</b> and tensioning component <b>2310</b> of at least <figref idref="DRAWINGS">FIG. 23</figref> are configured in a manner substantially similar to plate <b>1004</b> tensioning component <b>1006</b> of at least <figref idref="DRAWINGS">FIG. 10A-D</figref>, with at least the exception of ridged friction surfaces <b>2314</b>. Still other lace fixation assembly embodiments are possible.

0062Referring now to <figref idref="DRAWINGS">FIGS. 24A-B</figref>, fourth lace fixation assembly <b>2400</b> is shown in accordance with the present disclosure. In the example embodiment, fourth assembly <b>2400</b> is substantially similar to second lace fixation assembly <b>1002</b> as described above. Fourth assembly <b>2400</b> though is configured to exhibit coiler functionality. As shown in particular by the sequence of <figref idref="DRAWINGS">FIG. 24B</figref>, tensioning component <b>1006</b> may initially be pulled in direction F so that tension member <b>1010</b> in turn is pulled through plate <b>1004</b>. Post <b>2402</b> of plate <b>1004</b> may then be rotated in direction G to pull and wind tension member <b>1010</b> to groove <b>1024</b> formed by plate <b>1004</b> (e.g., see <figref idref="DRAWINGS">FIG. 10</figref>). Tensioning component <b>1006</b> may then be snap-coupled onto flange <b>1026</b> of plate <b>1004</b> in manner as described above. In the example embodiment, post <b>2402</b> of plate <b>1004</b> may be configured and arranged as a rotary dial having a clock spring or spiral-wound torsion spring so that tension member <b>1010</b> may be automatically wound to groove <b>1024</b> formed by plate <b>1004</b> without a user having to use tensioning component <b>1006</b> to wrap tension member <b>1010</b> to groove <b>1024</b> as describe above. In this manner, the user may simply pull tensioning component <b>1006</b> in direction F and then release tensioning component <b>1006</b> or gently guide tensioning component <b>1006</b> as post <b>2402</b> automatically rotates in direction G to wind tension member <b>1010</b> about groove <b>1024</b>. In other embodiments, the user may rotate post <b>2402</b> in direction G to wind the tension member <b>1010</b> about groove <b>1024</b>. In some embodiments, post <b>2402</b> may further be configured and arranged to exhibit push-to-lock/pull-to-unlock functionality whereby when tension member <b>1010</b> is fully wrapped to groove <b>1024</b> tensioning component <b>1006</b> may be pressed to lock second assembly <b>1002</b>. A reverse operation may be performed to unlock second assembly <b>1002</b> so that tension member <b>1010</b> may be unwound from groove <b>1024</b>. Still other lace fixation assembly embodiments are possible.

0063Referring now to <figref idref="DRAWINGS">FIG. 25</figref>, fifth lace fixation assembly <b>2500</b> is shown in accordance with the present disclosure. In the example embodiment, fifth lace fixation assembly <b>2500</b> is substantially similar to second lace fixation assembly <b>1002</b> as described above. Fifth assembly <b>2500</b> though is configured to exhibit incremental tightening/loosening functionality. For example, as shown in particular by the sequence of <figref idref="DRAWINGS">FIG. 25</figref>, tensioning component <b>1006</b> may initially be pulled in direction H so that tension member <b>1010</b> in turn is pulled through plate <b>1004</b>. Tensioning component <b>1006</b> may then be used to wrap tension member <b>1010</b> to groove <b>1024</b> and then snap-coupled onto flange <b>1026</b> of plate <b>1004</b> in manner as described above. Subsequently, a fine tuning operation may be performed to increase or release tension on tension member <b>1010</b>. In particular, tensioning component <b>1006</b> may be incrementally rotated in a clockwise direction in a fixed ratcheting motion to increase tension on tension member <b>1010</b>, or incrementally rotated in a counterclockwise direction in the fixed ratcheting motion to release tension on tension member <b>1010</b>. In the example embodiment, post <b>2402</b> of plate <b>1004</b> (e.g., see <figref idref="DRAWINGS">FIG. 24</figref>) may be configured and arranged as a ratcheted rotary dial so that tension on tension member <b>1010</b> may be increased or decreased as desired, without having to decouple tensioning component <b>1006</b> from plate <b>1004</b>.

0064Although the various disclosed lace fixation assemblies and systems are described in the context of a closure system for footwear or other panels desired to be closed toward one another, it will be appreciated that the designs may be optimized for a variety of other uses in which a lace or cord is desired to be removably secured at various tension levels or adjustment lengths. Examples include: a) fixation of high tensile rigging aboard ships, allowing for easy adjustment of a given line with secure fixation, b) orthopedic bracing products, c) garment closures, d) equestrian accessories, e) wakeboard boots, f) kitesurfing line adjustments, g) backpack and luggage closures.

0065Having described several embodiments, it will be recognized by those of skill in the art that various modifications, alternative constructions, and equivalents may be used without departing from the spirit of the invention. Additionally, a number of well-known processes and elements have not been described in order to avoid unnecessarily obscuring the present invention. Accordingly, the above description should not be taken as limiting the scope of the invention.

0066As used herein and in the appended claims, the singular forms “a”, “an”, and “the” include plural referents unless the context clearly dictates otherwise.
