Description

Technical Field

[0001] The utility model relates to the technical field of wheelchairs, in particular to a wheelchair leg support structure. Background Art

[0002] The wheelchair leg guard is an important part of the wheelchair design. Its main function is to provide a support point for the calves of the wheelchair user to prevent the legs from sliding backwards from the pedals while riding.

[0003] The existing wheelchair design generally adopts a positioning belt with a fur surface wrapped around the wheelchair frame, which is similar to Velcro. This positioning belt cooperates with the hook surface on the leg guard to achieve the detachable fixation of the leg guard.

[0004] However, in actual use, since the positioning belt is fixed around the vertical tube of the wheelchair frame, the two ends of the positioning belt abut against each other to form a connection. When the leg guard is removed, the rough surface of the connection is often lifted up by the hook surface of the leg guard. Over time, the two ends of the positioning belt will gradually lift up from the wheelchair frame. This not only affects the overall aesthetics of the wheelchair, but also greatly reduces the user experience. Utility Model Content

[0026] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0027] The utility model provides a wheelchair leg support structure, such as Figures 1 to 9 As shown, it includes a front frame of the wheelchair, a positioning belt 1, an insulating belt 2 and a leg guard belt 3 for supporting the calf; the two ends of the two positioning belts 1 are respectively connected and clamped on the two vertical tubes 4 of the front frame of the wheelchair, and the two insulating belts 2 respectively cover the connection points at the two ends of the two positioning belts 1; the two ends of the leg guard belt 3 are respectively bypassed by the positioning belt 1 and returned to the inner side of the leg guard belt 3, and the surrounding part of the leg guard belt 3 and the outer surface of the positioning belt 1 are detachably adhered by means of a hook surface and a fleece surface, and the two ends of the leg guard belt 3 and the inner side of the leg guard belt 3 are detachably adhered by means of a hook surface and a fleece surface, so that the leg guard belt 3 is fixed to the front frame of the wheelchair.

[0028] The two ends of the two positioning belts 1 of the utility model are respectively connected and clamped on the two vertical tubes 4 of the front frame of the wheelchair, and the connection points of the two ends of the two positioning belts 1 are respectively provided with insulating belts 2. Since the connection points of the two ends of the positioning belts 1 are provided with insulating belts 2, when the leg guard belt 3 is removed, the connection points of the two ends of the positioning belts 1 will not be lifted up together with the leg guard belt 3, and the positioning belts 1 can also be continuously fixed on the vertical tubes 4 of the front frame of the wheelchair, thereby extending the service life of the positioning belts 1, reducing the cost of manual maintenance, and improving the user experience.

[0029] like Figure 1 , Figure 4 and Figure 5 As shown, the two ends of the positioning belt 1 are abutted against each other to form a closed loop. The length of the positioning belt 1 in this embodiment matches the circumference of the vertical tube 4 of the front frame of the wheelchair, so that there is no excess material between the two ends of the positioning belt 1 after it is fixed to the vertical tube 4, ensuring that there is no gap between the positioning belt 1 and the vertical tube 4. This design can ensure that the insulating belt 2 is more compact when it is arranged at the connection between the two ends of the positioning belt 1, thereby improving the insulating effect.

[0030] like Figure 1As shown, the first hook surface 5 is provided at both ends of the leggings 3, and the first fur surface 6 is provided inside the leggings 3. The first hook surface 5 at the place where the leggings 3 are surrounded is attached to the surface of the positioning belt 1 in a detachable manner, and the first hook surfaces 5 at both ends of the leggings 3 are attached to the first fur surface 6 inside the leggings 3 in a detachable manner. The first hook surface 5 is provided at both ends of the leggings 3 of this embodiment, and the second fur surface 6 is provided inside the leggings 3. The first hook surface 5 cooperates with the first fur surface 6 to facilitate users to quickly install and remove. In other embodiments, the two ends of the leggings 3 can also be provided with fur surfaces, and the inside of the leggings 3 can also be provided with hook surfaces, while the positioning belt 1 should be provided with hook surfaces, and the isolation belt 2 should be provided with fur surfaces. In addition, in addition to directly providing hook surfaces or fur surfaces on the leggings 3, Velcro can also be provided directly at both ends of the leggings 3 and inside the leggings 3. Similarly, the Velcro at both ends of the leggings 3 can be hook surfaces or fur surfaces, and the Velcro on the inside of the leggings 3 can be hook surfaces or fur surfaces.

[0031] like Figure 1 , Figure 4 and Figure 5 As shown, one side of the positioning belt 1 is a second furry surface 8, and the other side of the positioning belt 1 is a rubber surface 9, and the first hook surface 5 of the leg guard 3 is detachably attached to the second furry surface 8 on the outer surface of the positioning belt 1. One side of the positioning belt 1 of this embodiment is a second furry surface 8, and the other side is a rubber surface 9. During installation, the second furry surface 8 of the positioning belt 1 faces outward, so that when the two ends of the leg guard 3 are wrapped around the positioning belt 1, the first hook surface 5 of the leg guard 3 cooperates with the second furry surface 8 of the positioning belt 1 to achieve the fixation of the leg guard 3 and the positioning belt 1 at the wrapping point. By adopting the detachable connection method of the hook surface and the furry surface, the user can quickly adjust the tightness of the leg guard 3, and it also makes the adjustment process simpler, which is convenient for the user to install and disassemble.

[0032] like Figure 4 and Figure 5 As shown, the positioning belt 1 is fixed to the vertical tube of the front frame of the wheelchair by means of an adhesive surface 9 or glue. One side of the positioning belt 1 of this embodiment is a second rough surface 8, and the other side is an adhesive surface 9. The positioning belt 1 can be directly attached to the vertical tube 4 of the front frame of the wheelchair by means of the adhesive surface 9, which is simple to operate and more convenient and quick to install. In addition, the positioning belt 1 can also be attached to the vertical tube 4 of the front frame of the wheelchair by means of glue, and the glue can be evenly applied to the surface of the positioning belt 1 and the vertical tube 4, ensuring that when the positioning belt 1 is fixed to the vertical tube 4, there is no gap between the positioning belt 1 and the vertical tube 4, so that the positioning belt 1 is more firmly arranged on the vertical tube 4.

[0033] like Figure 1 , Figure 6 and Figure 7As shown, one side of the insulating tape 2 is a second hook surface 7, and the other side of the insulating tape 2 is a smooth surface 10. The second hook surface 7 of the insulating tape 2 covers the second rough surface 8 pasted at the connection of the positioning tape 1. In this embodiment, one side of the insulating tape 2 is a second hook surface 7, and the other side is a smooth surface 10. When both ends of the leg guard 3 are wrapped around the outer surface of the positioning tape 1, the first hook surface 5 of the leg guard 3 is easily pasted on the second rough surface 8 at the connection of the outer surface of the positioning tape 1. The second rough surface 8 at the connection of the outer surface of the positioning tape 1 and the first hook surface 5 of the leg guard 3 are isolated by the insulating tape 2, so that when the leg guard 3 is disassembled, the connection of the positioning tape 1 will not be lifted up by the leg guard 3, thereby extending the service life of the positioning tape 1, and the structure is simple.

[0034] like Figure 2 and Figure 3 As shown, the heights of the two positioning belts 1 are at the same horizontal line. In this embodiment, the heights of the two positioning belts 1 on the vertical tube 4 are at the same horizontal line. Of course, the user can adjust the heights of the two positioning belts 1 according to actual needs so that the leg guard belt 3 reaches the most suitable height for leg support.

[0035] like Figure 2 and Figure 3 As shown, a U-shaped tube 12 for feet to be placed is provided at the bottom of the front frame of the wheelchair. A horizontal tube 11 is provided between the two vertical tubes 4 of the front frame of the wheelchair in this embodiment, and the U-shaped tube 12 is connected to the horizontal tube 11 for feet to be placed. The user's legs are supported by the leg guards 3, and the feet can be placed on the U-shaped tube 12 or the horizontal tube 11, providing a variety of foot placement methods, and the design is humanized.

[0036] The use process of the utility model is as follows:

[0037] During installation, the user uses glue to fix the two positioning belts 1 at appropriate heights on the two vertical tubes 4 of the front frame of the wheelchair according to their own situation, and sticks the two isolation belts 2 to the second rough surface 8 at the connection of the outer surface of the positioning belt 1 through the second hook surface 7, then wraps the two ends of the leg guard belt 3 around the positioning belt 1 respectively, and sticks the first hook surface 5 at the two ends of the leg guard belt 3 to the first rough surface 6 on the inner side of the leg guard belt 3, and the first hook surface 5 at the encircling part of the leg guard belt 3 is also stuck to the second rough surface 8 on the outer surface of the positioning belt 1, and the installation is completed.

[0038] When disassembling, it is only necessary to tear the two ends of the leg guard band 3 to separate the first hook surface 5 at both ends of the leg guard band 3 and the first furry surface 6 on the inner side of the leg guard band 3, and then tear off the first hook surface 5 at both ends of the leg guard band 3 from the second furry surface 8 on the outer surface of the positioning band 1. Since an isolation tape 2 is provided at the connection of the outer surface of the positioning band 1, the user does not have to worry that the connection of the outer surface of the positioning band 1 will be lifted up by the leg guard band 3, and the disassembly is now completed.
