FIELD OF THE INVENTION The present invention relates to a shoe, in particular a sports, leisure or rehabilitation shoe, which has a central locking system with a solid form-locking lacing which allows movement in the direction of the toe of the foot or in the opposite direction. provided with a tensioning element, alternating from the upper side guide groove, alternating in the direction of the toe of the shoe, it is always passed through one of the pivoting pivots and always connected to the side section through a pivoting member or crossing the pivoting section and then through a further pivoting portion of the side section.

Such shoes are described in DE-U-8 912 788. reported. There, there is a rust boron made of a hard elastic material over a soft elastic tongue. On the front of the shoe, the flip-flops are fitted with side-flap closure flaps that are firmly secured to the side of the shoe. The center lock is firmly attached to the pan, so it cannot be separated. From the central lock, at least one cord-like tensioning element guides alternately through the pivoting elements of the closing flaps and the barb. The central locking, busting and locking flaps form a prefabricated, pre-tested and safely functioning technical unit.

DE-A-2,341,658. The patent also discloses a slipper with a central lock and a tongue-shaped middle shoe, in which the middle shoe is hinged at the toe with the front of the shoe for easy access. The intended location of the central lock is located approximately in the center of the barrel, in the middle of the shaft, in the form of a pivotable clamping device. Starting from this central lock, a tensioning cord extends upwards and downwards, essentially crossing the middle leg portion. This tensioning cord forms a loop outside and, after reversing transversely through the middle stem portion and forming a new loop, is attached to the middle portion of the stem at the same height as the first loop on the other side of the stem portion. Opposite loops at the end of the dew, in the area of ​​the flexor of the foot, that is, between the foot and the shank

<img file="HUT65299A_D0001.tif" />

- 3 stems located around the joint. The other two loops are located on the ankle pads and the toe joints. Hooks are formed on the shoe's shoe. When the middle stem portion is folded up on the stem, the loops are placed on the hooks and the tensioning straps are tightened by rotating the clamping device by interposing the connected caster roller. The tensile clamping force, meanwhile, is always perpendicular to the protrusion of the central stem portion which always overlaps the stem sides. Although it is very possible to enter the slipper, it is very difficult and time-consuming to place the loops on the hooks at the closure, especially when the hooks are blocked by snow or ice.

It is an object of the present invention to eliminate the disadvantages of a shoe with a central lock so that, as in the case of a traditional shoe, the shoe laces can be replaced in a simple manner that allows the shoe to be adapted to the foot, Thus, despite the good attachment of the foot to the shoe, you should not restrict the movement of the foot either around the foot joints or around the upper and lower tibia.

Figure 1 is an exploded view showing the essential elements of the shoe 1 of the present invention. We note first of all that these are mainly athletic, casual or rehabilitation shoes, that is to say, unlike Alpine-style shoes, whose shoes do not consist of molded, shell-like stems, but are made of a single, flexible material or several pieces. consists of a flexible flexible material such as. leather, imitation leather, fiber fabric, or leather or leatherette. Such sneakers include, for example, sneakers, tennis and jogging shoes, or spacious sneakers, such as running, jumping, and the like.

Rehabilitation shoes, or shoes especially for rehabilitation purposes, are understood to mean mainly shoes that enable the removal of rigid fasteners, such as gypsum, sinus and the like, and the patient as soon as possible in the case of foot injury or foot surgery. become able to walk without fear of re-injury or secondary damage such as so-called. habit of defensive posture resulting in unhealthy posture. A more detailed description of such rehabilitation shoes is provided in DE-A-35 20 786. can be read in announcement.

The exploded shoe 1 comprises a detailed shoe 1 consisting of an unspecified sole, a shoe 2 consisting of lateral portions 3 and 4 of an upper portion, a heel portion 5, a front portion 6 and an insole 7.

• ··«

In each case, the edges 8 of the side portions 3 and 4 in the toe region of the foot are formed by a rigid main body 9 and 10 made of a flexible strip of elastic material 9.1 and 10.1. Both 9.1. and 10.1 have two longitudinal slots 11 and 12 respectively. Under the longitudinal slits 11 and 12, one end of a tensioning strip 13 and 14 extends from the side of the shoe 2 to both sides of the sole and is secured between the material of the shoe 2 and the material of the shoe sole.

A well-padded tongue 15 fits into a shoe opening made of soft, flexible material, preferably foamed plastic, which is inserted into the toe end 17 of the shoe 1, underneath the material of the shoe 2 and sewn or possibly glued are fixed so that it can be driven out. Meanwhile, the lateral jaws 18 and 19 of the tongue 15 fall below the lateral portions 3 and 4 of the shaft 2. Due to the distance between the tension strips 9.1 and 10.1 and the height of the edges 8 of the side sections 3 and 4 of the shoe 2, an opening 20 is formed which leaves a middle strip 21 at least 1.5 to 2 cm wide from the tongue 15.

In the tongue 15, in particular in the upper part of its central third, a flat recess 22 is inserted, into which recess 22 of a central lock 24 is inserted, which can be secured there by, for example, gluing, sewing or injection molding. The support plate 23 is made of a highly elastic, resilient and therefore hardly or very slightly flexible material, mainly of a hard, compact plastic such as polyamide, polyimide, ···; ···· .........

polyethylene and the like. The length 25 of the support plate 23 and the arrangement thereof on the central bar 21 of the tongue 15 are chosen such that the length 26 of the slide is about 20 cm. It covers 95%, whereby at least 5%, but preferably between 20% and 50%, of the front edge 27 of the support plate 23 and the fixed end 17 is free, and thus flexible. In addition, it has been found advantageous to have at least 10% of the length 26 of the tuft behind the rear edge 28 of the support plate 23 or to be covered only by the tongue portion 29 extended to the upper and lower hinges.

The support plate 23 is provided with a recessed base plate and a recess 30 formed in the form of rib sections 31 and 32, which formerly enclose it. A closure portion 33 may be disposed in this abutment portion 30, which may preferably be secured in this abutment portion 30 by adhesion.

The closing portion 33 is provided with a solid lower portion 34 having a lateral 35 and a lever 36 and a pivotable adjusting button 37. Between the lower part 34 and the adjusting knob 37 there is a lockable winding device, which may be provided with a release mechanism which can be effected by pressing a button 38 on both ends of the tension member 39 or the one part tension member. To turn the adjusting knob 37 in one direction, the tensioner 39 is twisted, while to turn it in the opposite direction, the tensioner 39 is unscrewed.

When the closure part 33 is inserted, the support plate 23 is surrounded by two arms 35 and 36 from the side. 35 and 36 in and / or under arms

<img file="HUT65299A_D0002.tif" />

The recesses 40 for guiding the tension member 39 are formed in the fitting portion 30 located.

The lower portion 34 is provided with securing projections 41 both on its front side and on its rear side (not shown). This engages the rib portions 31 and 32, respectively, when inserting the closure 33 through the opening 42 of the fitting portion 30, so that the closure 33 can be connected to the retainer 23 by a locking connection. The support plate 23 has a projecting projection 43. This projection 43 may itself be welded thereon and / or welded thereto and / or bonded and / or glued and / or ultrasonically welded. FIG. 1A is a top view 44 of the view shown in the direction of arrow I in FIG. 1, consisting of two shells. Between the upper shell 45 and the lower shell 46 there is provided a spaced distance 47 which is equal to or greater than the thickness of the tensioner 39. The two upper shells 45 and 46 are connected at their sides 48 and 49 by pivoting members 50 and 51 in the intermediate space 47 connected to the tensioner 39. However, it is most preferred that the projection and / or the upper portion 44 is made of a single piece, for example by injection molding or extrusion. The upper portion 44 may be provided with stiffening ribs 52 and 53 extending downwardly on each side 48 and 49, respectively.

Through the intermediate area 47 of the top portion 44, the tensioning member 39 is transverse rearward during assembly to form loops at the top and bottom that engage the pivoting members of the side sections 3 and 4, as shown in Figure 2.

Figure 2 is a top plan view of the shoes 1 of the components shown in Figure 1. In its cross section, the lateral jaws 18 and 19 of the tongue 15 are approximately at least 60% of the surface area of ​​the forefoot shown above, approximately in the cross section of the foot. The outer faces of the side jaws 18 and 19 also serve as sliding surfaces 4 of the side portions 3 and 4 in contact with them.

According to one aspect of the invention, tensioner sections 54 and 55 are guided in the uppermost guide grooves 35, 36 in the guide grooves closest to the corner 5 and / or in the recesses 40 of the arms 35 and 36 at the lower part 34 of the closure. firstly, through the pivoting members which are in force with the side portions 3 and 4, they are led to the pivoting members 50 and 51 of the cover sheet 23 and hence to a further front pivoting member 58 and 59, from where they eventually return to the front portion of the central strip 21 of the tongue 15. In the case of a one-piece clamping member 39, the retractable portion 60 is located in the transverse groove 61 of the central strip 21 of the tongue 15. This can additionally be retracted into a miracle 62. The section 60 may also be protected against lateral displacement in the transverse groove.

Even if, as in the embodiment of Fig. 2, there are two pivoting members in each of the side portions 3 and 4, it is possible in principle to place additional pivoting members therein which can be properly engaged with the other pivoting members on the support plate 23. . In principle, it is also possible to form the guide of the tension member such that, for example, the tension members 63, 64, or 65, 66 · ·····································································································································································

The sections 13 intersect each other in the area 23 of the support plate 23 under the central lock 24.

For 39 tensioning elements&gt; 2 tensioner sections

These ends are fixed either around the transverse grooves 61 of the tongue 15 or on the side members 3 and 4.

As shown in Figure 2, at least two of the uppermost lateral tension portions 54 and 55 of the tensioner 39, and more particularly the two subsequent tensioner portions 63 and 64, are inclined from the guides on the support plate 23 and the middle strip 21 of the tongue 15. rearwardly guided to the pivoting members 56 and 57 and 58 and 59 respectively. As a result, the tensile stress at closure in the uppermost or the two uppermost tensioner sections 54 and 55 and 63 and 64 will act in the direction of the corner portion 5. Advantageously, the tensioning belts 13 and 14 are also arranged so that the tensile stresses are applied partly downwards in the direction of the sole and partly in the rearward direction towards the heel portion 5.

The further tensioner sections 65, 66 and 60 are preferably configured to extend obliquely forward or transversely to the tongue 15 from the support plate 23 or the central strip 21 of the tongue 15.

In order for the tensioning voltage to be effectively applied to the tensioning belts 13 and 14, the respective pivoting members 56, 57 and 58, 59 are disposed or formed on the head 67 of the tensioning belts 13 and 14, as shown in Figs. can also be clearly seen in the figures. The head section 67 is inserted into a slit 68 of a lower batt 10.1 facing the elongated slots 11 and 12 and engages with the lower edge of the slit 68 by means of a snap-shaped nose 69.

Slots 11 and 12 for Introducing Stretch Belt 39 »

behind it is an abutment, such as a rib-shaped abutment, on which the leading edge 72 of the headpiece 61 may strike after defeating a certain height of a few millimeters.

The upper portion 73 of the pivoting members 56 and 57 and 58 and 59 has a flange 75 extending beyond the surface of the upper portion 73. The resulting groove 76 for the tensioning member 39 is in the same plane as the slits 11 and 13. The protruding flange 75 is separated by a slot 77 for insertion of the tension member 39, 14 and 14, respectively, on the side facing the front edge 72 of the head section 67.

Preferably, the tension bars 9.1 and 10.1 are always provided with a properly formed fastening plate 78. The tension strips 39 can be secured to the stem material by sewing and / or gluing and / or riveting using these fastening flaps 78. Preferably, the anchoring flaps 78 are configured so that the slots 11, 12, or slots 68, extend in a plane and their upper plane is flush with the lower edge of the slit 68.

Preferably, the tongue 15 is made of a foamed polymer, in particular a thermoplastic pressure transfer padding material, such as foamed polyethylene, polyurethane or ethylene vinyl acetate. The bottom side of the tongue 15 is provided with a textile coating 79 as shown in Figures 2 and 3. The upper half or part of the 15 tongues is also covered with textile, • · ·

- Padded or laminated with 15 skins or other traditional footwear materials.

The stiffeners 9, 10 and the slats 9.1 and 10.1

they are mainly made of flexible plastics, mainly polyamide, polyimide, polyurethane, etc. This also applies to the straps 13 and 14, which consist mainly of the aforesaid but transparent types of plastics in order to make the designations of the shoes in question recognizable.

1-6. In the embodiments of the invention illustrated in Figures 1 to 9, where the stiffening members 9 and 10 and the straps 9.1 and 10.1 can be mechanically connected to the shoe straps 13 and 14 and thereby to the shoe stalk and / or sole, a shoe abundance control system can be provided. , which adjusts the inside size of the shoe precisely to the circumference of the foot. Meanwhile, the central lock 24 performs a multi-purpose function. Not only does it serve to provide evenly distributed closure pressure across the entire shoe area, it also provides increased stability for the entire shoe, in the sense that it greatly reduces the risk of over-stretching sensitive joints and tendons, especially on the outside of the shoe.

It has been found to be particularly advantageous that the closure portion 33 described above, together with the tensioning member 39, can be detached from the support plate 23 and can be practically replaced with a shoelace. Thus, the central closure 33, together with the tensioning member 39, can be manufactured as a component of the shoe according to the invention and tested for its functionality. Nevertheless, the central closure 33, including the tensioning member 36, nevertheless • · * *

- Even after assembling with 1 shoe, 16 can be replaced, according to the principle of the cabinet. This will greatly reduce the error or debris percentage, which is the type shown

Particularly important for high-tech shoes.

The softly elastic tongue 15, which is designed to cover the body, serves as a pressure relief intermediate between the relatively rigid support plate 23 and the shoe wearer's feet. The support plate 23 is made of a hard, shape-retaining material, with a Shore hardness of 60-80 Shore D, most advantageous. Accordingly, the retaining plate 23 serves as a pressure distribution element without making the tongue 15 foldable at the end 17 of the tongue 15. The tongue 15 is made of a material much softer than the material of the support plate 23, and thus has a Shore hardness far below that of a Shore D 60.

In the design of the present invention, the shoe remains flexible in the area around the toe base and the tongue, especially the middle portion, is well adapted to its shape, i.e. the curves of the toe of the foot due to its soft elastic design. Because the central locking plate does not completely cover the entire length of the muzzle, as the underside of the tongue remains free and thus elastic, important foot mobility around the toe base is maintained for non-Alpine slippers. This, due to the proper choice of the length of the support plate, also provides unhindered mobility of the upper and lower tibia, which should not be restricted in the shoes according to the invention, let alone completely disengaged.
