[0036] FIG. 9 shows another alternative adjustable support frame with another alternative arrangement of actuation elements.
Detailed ways
[0037] Referring to FIG. 1, a breathing apparatus 10 is shown. In this example, the breathing apparatus 10 is a self-contained breathing apparatus (SCBA), but it should be understood that the principles of the present disclosure can be applied to other types of breathing apparatus having a supporting frame.
[0038] The breathing apparatus 10 includes an adjustable support frame 100, also referred to as a back plate, which supports the breathing cylinder 12. The valve device 14 is arranged to fix the gas cylinder 12 to the support frame 100 and transfer gas from the gas cylinder 12 for the user to breathe via a hose and a lung demand valve (not shown). It should be understood that the breathing apparatus is usually set to provide a supply of clean breathing air for its users in an environment where clean breathing air cannot be obtained in the surrounding environment, for example, in fires, chemical leaks, and the like.
[0039] The breathing apparatus 10 is configured to be worn by the user on the back of the user (see, for example, FIG. 9). To achieve this, the breathing apparatus 10 includes a shoulder strap 16 configured to be worn on the user's shoulders and surrounding the user's arms, and a waist belt 18 fixed around the user's waist.
[0040] Turning now to FIGS. 2, 3 and 4, the adjustable support frame 100 for the breathing apparatus 10 is shown in more detail. FIG. 2 shows the support frame 100 in a perspective view, showing the outwardly facing side 103 of the support frame 100. FIG. 3 shows a plan view of the support frame 100 viewed from the outside-facing side 103. FIG. 4 shows a plan view of the same support frame 100 from the side 102 facing the user.
[0041] As shown in FIGS. 3 and 4, the adjustable support frame 100 has an adjustable longitudinal dimension L, which is referred to as a length L in this detailed description. It should be understood that the longitudinal direction is the direction of the vertical extent of the support frame 100 in use. The term "longitudinal" can be understood as a substantially vertical direction in the use of the support frame. The longitudinal direction may be parallel to the extension direction of the spine or body when the user is standing. The term "lateral" may be understood here as a direction that is substantially horizontal in use of the support frame and extends generally laterally with respect to the user (ie, across the user). The lateral direction may be substantially parallel to the direction of the line extending between the user's shoulders and/or buttocks.
[0042] The length L of the support frame 100 is the total length of the support frame 100 in the longitudinal direction. The length L is adjustable, which will be discussed in more detail below with respect to FIGS. 5A and 5B.
[0043] The supporting frame 100 is formed by the first frame portion 104 and the second frame portion 106 of the lower portion. The first frame portion 104 and the second frame portion 106 are movable relative to each other in order to adjust the length L of the support frame 100, as will be described in more detail with respect to FIGS. 5A and 5B below.
[0044] In order to adjust the length L of the support frame 100, the support frame 100 includes an adjustment mechanism 108. The adjustment mechanism 108 is adjustable between a locked configuration and an unlocked configuration. The locking configuration prevents relative movement of the first frame portion 104 and the second frame portion 106, and the unlocking configuration allows relative movement of the first frame portion 104 and the second frame portion 106. This will be described in more detail below with respect to FIGS. 6A and 6B.
[0045] As shown in FIGS. 2 to 4, the adjustment mechanism 108 includes two actuation elements 110, which are operable to actuate the adjustment mechanism 108. The actuating element 110 is arranged on a surface 112 facing the user side 102 that is substantially perpendicular to the support frame 100. Generally, this should be understood to mean that the surface 112 faces sideways or upright relative to the user-facing side 102 (or some combination thereof, such as diagonally upwards or downwards). The actuation element 110 is provided on this surface so that the actuation element 110 will not be covered by the users back during use, nor will it be arranged outside the users reach on the exterior-facing side 103, so that the user can wear a support The frame 100 simultaneously actuates the actuating element itself. It should be understood that the surface 112 need not be exactly perpendicular to the user-facing side 102 of the support frame 100. On the contrary, the surface 112 should be arranged to be sufficiently out-of-plane with respect to the user-facing side 102 so that the actuating element 110 thereon can be approached from the side or the vertical direction (or some combination thereof) so that it is not affected by the user during use. The back is covered. For brevity in this detailed description, the surface on which one or more actuating elements are disposed may be referred to as the accessible surface 112.
[0046] In this example, the accessible surface 112 is a longitudinally facing surface. The accessible surface 112 faces (ie perpendicular to) the longitudinal direction of the support frame 100. The accessible surface 112 faces downward in use.
[0047] In this example, the support frame 100 includes a first frame stringer and a second frame stringer 114. The frame stringers 114 are laterally spaced apart on the support frame 100. In this example, the frame stringer 114 is telescopic, wherein the outer frame stringer 116 is provided on the lower frame portion 104, which receives the inner frame stringer 118 provided on the upper frame portion 106 (see FIG. 5B for more Details). Therefore, the inner frame longitudinal beams 118 can be drawn out from the outer frame longitudinal beams 116 to increase the length of the supporting frame 100. The frame stringers 114 extend along the support frame 100 in a substantially longitudinal direction.
[0048] The support frame 100 includes a bridge portion 120 that extends in a transverse direction substantially perpendicular to the frame stringer 114. In this example, the bridge portion 120 extends laterally between the two frame longitudinal beams 114. Furthermore, in this example, the bridge portion includes a bottle holder 122 for supporting the breathing gas cylinder 12 of the breathing apparatus 10 in use.
[0049] In this example, the actuating element 110 is provided on an accessible surface 112, which is the longitudinally facing surface of the bridging portion 120. In particular, the actuating element 110 is provided on the lower (in use) surface of the bridge portion 120. The bridging portion 120 has an opposite upper (in use) longitudinal facing surface 124, which faces upward in use.
[0050] In this example, the support frame 100 includes a hole 126 passing through the support frame 100 between the user-facing side 102 and the exterior-facing side 103. In this example, the hole 126 is substantially rectangular and is defined on its lateral side by the frame stringer 114, on its upper side by the bridging portion 120, and on its lower side by the base of the support frame 100. Part 128 is defined. It should be understood that the hole 126 is an opening or window passing through the support frame 100.
[0051] The hole 126 is bounded by the peripheral wall 130. The peripheral wall 130 is formed as a substantially rectangular peripheral wall in this example, and the peripheral wall includes a portion formed by the frame stringer 114, the bridge portion 120 and the base bridge portion 128. Other shapes of holes can be envisaged, such as circular or elliptical holes with corresponding peripheral walls. In this example, the accessible surface 112 on which the actuation element 110 is disposed is part of the peripheral wall 130 of the hole 126. It should be understood that by providing a hole 126 through the support frame 100, the one or more actuation elements are therefore accessible on the outwardly facing side of the support frame 100. Therefore, it can be easily approached by others standing behind the user other than the user. This can provide a more convenient and versatile adjustable support frame.
[0052] In other examples, instead of a hole extending completely through the support frame 100, a protrusion (ie, a protrusion space) may be provided. The protrusion may be defined by the peripheral wall like the hole 126 described above. However, the protrusion may not extend completely through the support frame
The depth of the hole is formed.
[0053] In this example, the actuating element 110 extends from the peripheral wall 130 into the hole 126, and in particular, extends from the accessible surface 112 of the bridging portion 120 into the hole. In other words, the actuating element 110 protrudes or protrudes from the peripheral wall to extend into the hole 126. This extension of the actuating element 110 may enable it to be more easily grasped by the user. The actuating element 110 of this example is formed with an elongated graspable portion 132 that extends longitudinally from the accessible surface 112, that is, substantially parallel to the user-facing side 102.
[0054] Referring now to FIGS. 5A and 5B, the adjustment of the length of the support frame 100 will be briefly described.
[0055] FIG. 5A shows the support frame 100 in a first configuration, which in this example is the shortest possible configuration, with a total length L1. In FIG. 5A, the inner frame stringer 118 is completely received within the outer frame stringer 116.
[0056] In FIG. 5B, the support frame 100 is shown in the second configuration, where the total length of the support frame 100 is the extension length L2. In this configuration, the inner frame stringer 118 has protruded a distance D from the outer frame stringer 116, so that the overall length of the support frame 100 is increased. As should be understood, the difference between the lengths L1 and L2 is the distance D. The distance D is adjusted by extracting and inserting the inner frame longitudinal beams 118 of different lengths into the outer frame longitudinal beams 116, and the length L of the supporting frame can be adjusted to suit the size of the user.
[0057] Of course, it is undesirable that the length L of the support frame is unexpectedly changed, so the adjustment mechanism 108 prevents the relative movement of the frame portions 104, 106 (ie, the movement of the inner frame stringer 118 relative to the outer frame stringer 116) unless it is Move to its unlocked configuration.
[0058] The configuration of the adjustment mechanism 108 will now be described in more detail with respect to FIGS. 6A and 6B.
[0059] Each of FIGS. 6A and 6B shows a close-up view of the upper portion of the support frame 100 facing the user side 102.
[0060] In FIG. 6A, the adjustment mechanism 108 is shown in a locked configuration. It can be seen here that the adjustment mechanism 108 includes a pair of opposed bolts 134, each bolt extending transversely into a frame stringer 114 in opposite directions. The bolt 134 extends through the outer frame stringer 116 and into the inner frame stringer 118.
[0061] The inner frame stringer 118 includes a plurality of longitudinally spaced recesses 136 separated by a wall 138. The notch 136 provides a plurality of discrete lengths for the support frame 100.
[0062] In this locked position, the bolt 134 extends into a recess 136 such that the contact between the bolt 134 and the wall 138 prevents the inner frame stringer 118 from moving longitudinally relative to the outer frame stringer 116. Therefore, in the locked position of the adjustment mechanism 108, the upper frame portion 104 and the lower frame portion 106 cannot move relative to each other, and the length L of the support frame is locked.
[0063] FIG. 6B shows the adjustment mechanism 108 in an unlocked position.
[0064] In order to move the adjustment mechanism 108 to the unlocked position, the user can grasp the actuating elements 110, even when wearing the support frame 100, can also conveniently access these actuating elements on the accessible surface 112, and to actuate The element 110 applies a force F (see FIG. 6A) to push the actuation elements 110 toward each other to the position shown in FIG. 6B.
[0065] Each actuation element 110 is attached to a corresponding one of the bolts 134. The bolts 134 are slidably moved out of the inner frame stringer 118, so that when the actuating elements 110 are pushed together, each bolt 134 is withdrawn from the corresponding inner frame stringer 118, and importantly from the recess in which it is located Draw out of 136. In this position, the bolt 134 no longer prevents the longitudinal movement of the inner frame stringer 118 relative to the outer frame stringer 116, so as long as the actuating elements 110 are pushed together, the length of the support frame 100 can be adjusted freely.
[0066] Once the support frame is adjusted to the desired length, the actuating element 110 can be released. The bolt 134 is biased (by a spring, etc.) to return to the locked position, so when the actuation element 110 is released, the bolt 134 slides back to the inner frame stringer 118
And the nearest notch 136, and enter the locking configuration of FIG. 6A.
[0067] It should be understood that the support frame 100 is configured such that the actuation element 110 maintains a substantially static longitudinal position relative to a portion of the user's back. In the exemplary support frame 100, the lower frame portion 104 includes a waist belt for fixing the lower frame portion in a fixed position on the waist or lower torso of the user. The one or more actuating elements are also provided on the lower frame part so that once the waist belt has been fixed to the user's waist, even when the length L is adjusted, it also maintains a substantially fixed position relative to the user's waist.
[0068] In an alternative arrangement, the actuation element may be provided on the upper frame portion 106 with the upper end of the shoulder strap attached to the upper frame portion. In this alternative example, once the user has put on the shoulder strap, the actuation element will maintain a substantially fixed position relative to the user's shoulder even when the length L is adjusted.
[0069] These arrangements can make the actuation element 110 easier to find and actuate when the user wears the support frame 100, because it is in a reliable static position during use.
[0070] As described in this application, providing an actuation element for the adjustment mechanism provides a significant advantage in that the length of the support frame can be easily adjusted when the breathing apparatus is in use. In prior art support frames, the design goal is usually to provide a system that prevents the length of the support frame from being adjusted in use, so as to avoid accidental adjustments. However, such a system can prevent a quick response to emergency situations, because if the support frame is adjusted incorrectly, the breathing apparatus may need to be completely taken off for adjustment. On the contrary, the support frame according to the present disclosure is very easy to adjust when putting on the breathing apparatus.
[0071] FIG. 7 shows a user wearing a breathing apparatus 10 that includes a support frame 100 and actuates an actuation element 110 provided on an accessible surface as described herein. As will be understood, since the actuation element is provided on a surface substantially perpendicular to the user-facing side, the user himself can reach around the actuation element itself with one hand and actuate the element itself. In addition, in the example shown in FIG. 7, the hole 126 passing through the support frame 100 provides other personnel with easy access to the actuating element 110 without having to surround the side of the frame 100 to reach the gap between the user and the frame 100. In an enclosed space. Therefore, the length of the support frame 100 can be adjusted very conveniently during use.
[0072] Figures 8 and 9 show an alternative configuration of a support frame incorporating the principles of the present disclosure.
[0073] FIG. 8 shows an alternative support frame 200 with actuation elements 210 provided on a laterally accessible surface 212 provided on the side surface of a frame stringer 214. In this example, the user can reach into a small part of their back to actuate the actuation element 210.
[0074] FIG. 9 shows yet another alternative support frame 300 having actuation elements 310 disposed on the opposite upwardly facing accessible surface 312 on the bridge portion 320. In this example, the user can extend their head (in a manner similar to triceps extension) to access and actuate the actuation element 310.
[0075] In order to avoid unnecessary repetitive efforts and repetition of Chinese text, only certain features are described in relation to one or several aspects or embodiments of the present invention. However, it should be understood that, where technically possible, the features described in relation to any aspect or embodiment of the present invention can also be used with any other aspect or embodiment of the present invention.
[0076] Those skilled in the art should understand that although the present invention has been described with reference to exemplary examples by way of example, it is not limited to the disclosed examples, and may not depart from the scope of the present invention defined by the appended claims. In the case of constructing an alternative instance.
