Description

Technical Field

[0001] This utility model belongs to the field of wheelchair accessories technology, specifically relating to a storage mechanism for wheelchairs. Background Technology

[0002] A wheelchair is a chair equipped with wheels that can help replace walking. It is an important means of transportation for the injured, sick, disabled and other people with limited mobility. The emergence of wheelchairs has provided great convenience for people with limited mobility, helping them to better integrate into society and life.

[0003] However, looking at all current wheelchairs, none of them have a built-in storage box for placing items. When a storage box is necessary, it is usually carried on the back or hung on the back. Carrying on the back puts pressure on the person, and hanging on the back is unstable and hinders the movement of the wheelchair. Furthermore, when hanging on the back, if the user is traveling alone, the backpack is usually hung on the back of the wheelchair. To get something, the user has to reach behind the back to get it, which is very inconvenient. Therefore, it is necessary to optimize the structure of wheelchair components. Utility Model Content

[0004] In view of the problems mentioned above in the background art, the purpose of this utility model is to provide a storage mechanism for wheelchairs.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A storage mechanism for a wheelchair includes a base plate mounted on a wheelchair, an adjustment plate slidably mounted on the base plate, Velcro straps that can be adhered to each other on the base plate and the adjustment plate, and a slot at the center of the adjustment plate.

[0007] The end of the adjustment plate is hinged to a bending plate, and the bending plate is provided with a clearance groove whose position and size correspond to the insertion platform.

[0008] A mounting plate is hinged to the end of the bent plate. A storage box is mounted on the mounting plate. A pin holder and a guide plate are mounted on the mounting plate. A pin is slidably mounted on the pin holder and the guide plate. A retaining ring is fixedly mounted on the pin. A spring is installed between the retaining ring and the pin holder. The spring is sleeved on the outside of the pin.

[0009] Furthermore, the substrate is provided with a sliding groove, and the adjusting plate is fitted with a locking screw located in the sliding groove. This design can fix the position of the adjusting plate after it is in place, preventing further displacement of the adjusting plate from pulling on the Velcro strap and thus preventing it from falling off.

[0010] Furthermore, the cross-sections of the substrate, the adjusting plate, the bending plate, and the mounting plate are all U-shaped. This design allows the upper and lower sides of each plate to be supported, and also provides clearance space inside.

[0011] Furthermore, the end of the pin is connected to a handle, a design that facilitates the insertion and removal of the pin.

[0012] Furthermore, the base plate is threaded with reinforcing screws, the ends of which contact the adjusting plate. This design further reinforces the position of the adjusting plate, prevents displacement of the adjusting plate, and ensures the installation stability of the entire mechanism.

[0013] Furthermore, both the base plate and the adjustment plate are equipped with hooks. This design allows the hooks on both sides to hook onto the wheelchair backrest frame from the outside, thus the installation is not restricted by the backrest cushion and achieves a rigid installation. In addition, the straps further enhance the stability.

[0014] The beneficial effects of using this utility model are as follows:

[0015] With the structural design of this utility model, when the storage box is not in use, the storage box is located at the rear of the wheelchair, which does not affect the normal movement area of ​​the wheelchair user, and thus does not affect the wheelchair user experience.

[0016] With the structural design of this utility model, when using the storage box, it can be moved to the front of the body through operation without sinking, which is convenient for wheelchair users and ensures the effectiveness of use;

[0017] With the structural design of this utility model, the storage box can be moved to the front of the body without sinking. Therefore, when the storage box is a hard object, it can also be used as a support platform, thus expanding its applicability. Attached Figure Description

[0027] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] like Figures 1-5 As shown, a storage mechanism for a wheelchair according to the present invention includes a base plate 2 mounted on a wheelchair 1, an adjustment plate 3 slidably mounted on the base plate 2, Velcro straps 4 that can be glued together on the base plate 2 and the adjustment plate 3, and a socket 5 mounted at the center of the adjustment plate 3.

[0029] A bent plate 6 is hinged to the end of the adjusting plate 3. The bent plate 6 is provided with a clearance groove 7 that corresponds to the position and size of the insertion platform 5.

[0030] A mounting plate 8 is hinged to the end of the bent plate 6. A storage box 9 is mounted on the mounting plate 8. A pin platform 10 and a guide platform 11 are mounted on the mounting plate 8. A pin 12 is slidably mounted on the pin platform 10 and the guide platform 11. A retaining ring 13 is fixedly mounted on the pin 12. A spring 14 is installed between the retaining ring 13 and the pin platform 10. The spring 14 is sleeved on the outside of the pin 12.

[0031] In this embodiment, when using a wheelchair storage mechanism, the storage box 9 is located on the back of the wheelchair 1 when not in use. Because the end of the pin 12 is kept in the insertion position 5 under the elastic force of the spring 14, the angle between the mounting plate 8 and the adjusting plate 3 cannot be changed. Therefore, the overall position of the storage box 9 cannot be changed, it does not interfere with the movement of the wheelchair, does not interfere with the normal use area of ​​the wheelchair user, and will not sway on the back of the wheelchair.

[0032] For the installation of the storage box 9, the adjustment plate 3 is pulled in the base plate 2 so that the overall length is adapted to the width of the wheelchair 1, and then the Velcro strap 4 is used to tie it to the back of the wheelchair 1. This installation method is suitable for the installation of wheelchairs 1 of different widths and has strong adaptability.

[0033] When the storage box 9 is needed, the latch 12 is pulled out from the socket 5. Then the bending plate 6 and the mounting plate 8 are no longer restricted in position by the latch 12 and the socket 5. Therefore, the angle of the bending plate 6 and the mounting plate 8 can be changed around the hinge axis. After bending the bending plate 6 and the mounting plate 8, the storage box 9 can be moved from the side of the wheelchair 1 to the front of the wheelchair 1. The wheelchair user can then operate the storage box 9. After the operation is completed, it is bent to the back side and then fixed in position using the latch 12.

[0034] The storage box 9 can be bent forward and will not fall under the support of the bending plate 6 and the mounting plate 8. Therefore, when the storage box 9 installed on the mounting plate 8 is a rigid storage box, the storage box 9 can also be used as a support platform, which expands its adaptability.

[0035] The preferred substrate 2 is provided with a sliding groove 21, and the adjusting plate 3 is fitted with a locking screw 22 located in the sliding groove 21. This design can fix the position of the adjusting plate 3 after it is in place, preventing further displacement of the adjusting plate 3 from pulling on the Velcro strap 4 and causing it to fall off. In fact, a sliding fixing structure between the substrate 2 and the adjusting plate 3 can also be considered depending on the specific situation.

[0036] Preferably, the substrate 2, adjusting plate 3, bending plate 6 and mounting plate 8 are all U-shaped in cross-section. This design allows the upper and lower sides of each plate to be supported, and there is clearance space inside. In fact, the cross-sectional shape of the substrate 2, adjusting plate 3, bending plate 6 and mounting plate 8 can also be considered according to the specific situation.

[0037] Preferably, the end of the pin 12 is connected to a handle 15. This design facilitates the insertion and removal of the pin 12. In fact, the shape and structure of the handle 15 can also be considered according to specific circumstances.

[0038] Preferably, the base plate 2 is threaded with a reinforcing screw 16, the end of which contacts the adjusting plate 3. This design can further reinforce the position of the adjusting plate 3, prevent displacement of the adjusting plate 3, and ensure the installation stability of the entire mechanism. In fact, the structure for fixing the position of the adjusting plate 3 can also be strengthened according to the specific situation.

[0039] Both the preferred base plate 2 and the adjustment plate 3 are equipped with hooks 17. With this design, the hooks 17 on both sides can hook the wheelchair backrest frame from the outside, so the installation is not restricted by the backrest pad and a rigid installation is achieved. In addition, the reinforcement of the 4 straps makes it more stable. In fact, the specifications and dimensions of the hooks 17 can also be considered according to the specific situation.

[0040] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
