Description

Wheelchair Devices

The invention relates to a wheelchair device, in particular to a wheelchair device which can assist a person to sit down and stand up.

A wheelchair is a chair with wheels that serves as an assistive device for people with limited mobility to replace walking. It is usually used by the injured, sick, disabled, elderly, etc. to facilitate their outdoor activities. Generally, wheelchairs are made of aluminum alloy, which can be easily folded, moved, and stored. Although wheelchairs have different structures of different sizes, they can be used by people of different body shapes.

Please refer to FIG. 1 . A general wheelchair 22 is a sitting structure. The height of the cushion 23 in the wheelchair 22 is about the knee position. However, for a passenger 21 with insufficient muscle strength, the height of the cushion 23 is too low. It is very strenuous to sit in the wheelchair 22. If the legs of the passenger 21 become weak, the buttocks will fall quickly and hit the cushion 23. It is very likely that the passenger 21 will be injured. Even if the sitting position deviates too much from the cushion 23, the passenger may fall. In addition, when the passenger 21 stands up from the wheelchair 22, the cushion 23 with too low height is very strenuous for the passenger 21 with insufficient muscle strength. The passenger 21 may also suffer muscle strain during the process of standing up.

In addition, some wheelchairs 22 are provided with a toilet to provide the passengers 21 with a convenient toilet, but the existing toilets are unsightly and the toilet is exposed when the passengers 21 leave the wheelchair 22, which reduces the passengers 21's willingness to leave the wheelchair 22. In addition, the existing toilet structure must be disassembled to clean the dirt.

As can be seen from the above description, the existing wheelchairs have the following disadvantages:

1. Prone to injury: Generally, wheelchairs adopt a sitting structure, which can lower the center of gravity and make it easier for caregivers to push the wheelchair. However, the height of the seat cushion in the wheelchair is about the knee level, which is too low for the injured. If the injured person feels pain or suddenly loses strength while sitting, he or she is prone to falling and other injuries. In addition, when the injured person gets up from the wheelchair, it is difficult to get up due to insufficient muscle strength, and it is also easy to get muscle strain.

2. Lack of aesthetics: Although wheelchairs with potties can provide passengers with the ability to use the toilet anytime and anywhere, the potty will be exposed when the passengers stand up. If the passengers do not want others to see the potty, they will stay in the wheelchair and are unwilling to stand and walk.

3. Dirt is not easy to clean immediately: The existing potty structure installed on the wheelchair is a detachable structure. When the passenger uses the toilet outside, the wheelchair must be moved home to disassemble and clean the potty. Since the dirt cannot be cleaned immediately, the passenger must endure the odor of the dirt during the movement.

Therefore, how to design a wheelchair that can cushion passengers when they sit down, assist passengers when they stand up, cover the toilet bowl, and facilitate cleaning of dirt is a goal that relevant technical personnel urgently need to work hard on.

In view of this, the object of the present invention is to provide a wheelchair device, which includes a support unit, a riding unit, and a buffer unit.

The supporting unit includes a supporting frame and a moving wheel set arranged on the supporting frame.

The riding unit includes a riding body arranged on the supporting frame. The riding body can move between a first position and a second position. The height of the first position is higher than that of the second position.

The buffer unit includes an elastic group connected to the support frame and the riding body, a stop structure arranged on the support frame, and an adjustment structure arranged on the stop structure. The adjustment structure is used to adjust the position of the stop structure and thereby control the height of the riding body at the first position. The elastic group provides elastic force to push the riding body to the first position and make the riding body abut against the stop structure. When the elastic group is compressed, the riding body moves to the second position.

Another technical means of the present invention is that the above-mentioned riding unit further includes an opening arranged on the riding body, and a removable accommodating bag set connected to the riding body, and the removable accommodating bag set is connected to the opening.

Another technical means of the present invention is that the above-mentioned pull-out type storage bag set has at least one lining part connected to the pull-out type storage bag set, and at least one storage part connected to the lining part, the lining part can be detachably attached to the upper surface of the riding body, and the storage part is penetrated through the opening.

One side of the riding body has two extension parts, and the two extension parts are movably arranged on the two upright setting parts. When the elastic group provides elastic force to push the riding body to the first position, the blocking rod abuts against the riding body.

Another technical means of the present invention is that the above-mentioned adjustment structure is a plurality of through holes arranged on the support frame, and the adjustment structure provides the stop rod for setting, thereby controlling the height of the stop rod.

The beneficial effect of the present invention is that the spring group can buffer the force during riding, thereby preventing the passengers from being injured, and can generate an upward thrust, making it easier for the passengers to stand up. The stop structure can limit the rising height of the riding body so that the spring group can use a stronger spring. The buffering seat can cover the removable storage bag group, and the removable storage bag group can be immediately packed and cleaned after containing dirt, so that the passengers can sit more comfortably.

The related patent application features and technical contents of the present invention will be clearly presented in the following detailed description of a preferred embodiment with reference to the drawings.

Please refer to FIG. 2 , FIG. 3 , and FIG. 4 , which are a preferred embodiment of the present invention's wheelchair device. The wheelchair device includes a support unit 3 , a seating unit 4 , and a buffer unit 5 .

The support unit 3 includes a support frame 31, a moving wheel set 32 arranged on the support frame 31, an armrest structure 33 arranged at two intervals on the support frame 31, and a handle structure 34 arranged at two intervals on the support frame 31. In the preferred embodiment, the handle structure 34 is composed of a cross column at the top of the support frame 31 and a grip sleeve arranged on the cross column, but is not limited to this.

The riding unit 4 includes a riding body 41 disposed on the support frame 31, a back support body 42 disposed on the support frame 31, an opening 43 disposed on the riding body 41, a cushioning seat 44 detachably disposed on the riding body 41, and a removable storage bag set 45 connected to the riding body 41.

The buffer unit 5 includes an elastic group 51 connected to the support frame 31 and the riding body 41, a stop structure 52 disposed on the support frame 31, and an adjustment structure 53 disposed on the stop structure 52.

The riding unit 4 is assembled in the supporting unit 3 to form a wheelchair structure, which can provide a person with limited mobility with a ride and move to other locations. Since the wheelchair structure is a known technology, it will not be described in detail here.

In the preferred embodiment, the front end of the riding body 41 is pivoted on the support frame 31, and the back support body 42 is arranged on the rear side of the riding body 41. The riding body 41 can move between a first position and a second position. The height of the first position is higher than the second position. The riding body 41 is horizontally arranged in the second position. The riding body 41 can be pivoted upward to the first position and is tilted in the first position. In actual implementation, the riding body 41 can be arranged on the support frame 31 in other ways, which should not be limited to this.

Referring back to FIG. 2 and FIG. 3 , the elastic group 51 is disposed between the handle structure 34 and the riding body 41 . The elastic group 51 is two springs. In actual implementation, the elastic group 51 can also be disposed at other positions, and the number of the elastic group 51 is not limited. For example, the elastic group 51 is disposed at the bottom of the riding body 41 and connected to the support frame 31 . This should not be limited to the example of the preferred embodiment.

The elastic group 51 provides elasticity to push the riding body 41 to the first position. When the riding body 41 moves to the second position, the elastic group 51 is compressed. In other words, when there is no passenger in the wheelchair device, the riding body 41 is pushed to the first position by the elastic group 51. When the passenger is already sitting in the wheelchair device, the riding body 41 is pressed down to the second position, and the elastic group 51 is compressed. The riding body 41 abuts against the support frame 31 and maintains a horizontal state. When the passenger stands up, the elastic group 51 can generate a thrust on the passenger, so that the passenger can stand up with less force.

Referring back to FIG. 2, FIG. 3, and FIG. 4, the adjustment structure 53 is used to adjust the position of the stop structure 52, and thereby control the height of the first position of the riding body 41. In the preferred embodiment, the stop structure 52 has two upright setting parts 521 correspondingly arranged on the support frame 31, and two stop rods 522 arranged on the upright setting parts 521. The rear side of the riding body 41 has two extension parts 411, and the two extension parts 411 are movably arranged in the two upright setting parts 521. When the elastic group 51 provides elastic force to push the riding body 41 to the first position, the stop rod 522 abuts against the riding body 41. The adjustment structure 5 3 denotes a plurality of through holes at different heights disposed on the support frame 31. The adjusting structure 53 provides the stop rod 522 for setting, thereby setting the height of the stop rod 522. After the riding body 41 is pushed by the elastic group 51, the two extensions 411 respectively abut against the two stop rods 522 of the stop structure 52, so that the riding body 41 is maintained at the first position. When the stop rod 522 is set at a higher position, the first position of the riding body 41 is also higher. When the passenger sits down, the passenger can contact the riding body 41 at a higher position. In actual implementation, the adjusting structure 53 can use other structures for fixing the riding body 41, and should not be limited to this. In addition, the two extension portions 411 extend backward from the two upright setting portions 521, the top end of the elastic group 51 is buckled on the handle structure 34, and the bottom end of the elastic group 51 is buckled on the extension portion 411. The elastic group 51 pushes the riding body 41 upward to the first position with the contracted elastic force.

It is worth mentioning that if the stop structure 52 is not provided on the support frame 31, the elastic group 51 will continue to pull the riding body 41, causing the elastic group 51 to use a spring with a smaller elastic force to prevent the height of the first position of the riding body 41 from being too high. However, the elastic group 51 with a smaller elastic force cannot effectively buffer the force of the passenger sitting down, nor can it effectively provide the passenger with the force to stand up. When the stop structure 52 is provided in the support frame 31, the caregiver can adjust the height of the first position of the riding body 41 to suit the height of the passenger sitting down and standing up. In addition, the elastic group 51 with a large elastic force can also be used to effectively buffer the force of the passenger sitting down and provide the passenger with the force to stand up.

Please refer to Figure 5 and Figure 6. The cushioning seat 44 can be arranged on the riding body 41 or on the back support body 42. When the cushioning seat 44 is arranged on the riding body 41, it can cover the opening 43 to prevent the opening 43 from being seen by other people. The cushioning seat 44 can be detachably arranged on the back support body 42. When the passenger needs to go to the toilet, the cushioning seat 44 can be moved from the riding body 41 to the back support body 42. When the passenger finishes going to the toilet, the cushioning seat 44 can be moved from the back support body 42 to the riding body 41. Preferably, Velcro is provided on the surface of the riding body 41, the side of the back support body 42, and the bottom of the cushion 44 so that the cushion 44 can be adhered to the riding body 41 or to the back support body 42. In actual implementation, the cushion 44 can use other combination structures and should not be limited to this.

Please refer to Figures 2, 7, and 8. The removable storage bag set 45 is connected to the opening 43. The riding unit 4 further includes a box 412 disposed below the riding body 41. The box 412 is connected to the opening 43. The removable storage bag set 45 is placed in the box 412. The removable storage bag set 45 is used to accommodate the excrement of the passengers when going to the toilet.

The removable storage bag set 45 has at least one pad portion 451 connected to the removable storage bag set 45, and at least one storage portion 452 connected to the pad portion 451. The pad portion 451 can be detachably attached to the upper surface of the riding body 41, and the storage portion 452 is penetrated through the opening 43. The pad portion 451 is a foldable structure. The folded pad portion 451 can pass through the opening 43, and the opened pad portion 451 can be attached to the riding body 41. When the pad portion 451 is folded, it can be stacked in the box 412.

Preferably, the opening 43 is elliptical, and the cushioning portion 451 is elliptical when unfolded, but the present invention is not limited thereto. The cushioning portion 451 can pass through the opening 43 when folded, and the cushioning portion 451 has thickness and elasticity. The cushioning portion 451 is unfolded and attached to the riding body 41, which can provide the passengers with a comfortable riding feeling. After the cushioning portion 451 is unfolded, it is attached around the opening 43, and the accommodating portion 452 naturally hangs down from the opening 43 to receive the excrement of the passengers when going to the toilet. When the passenger goes to the toilet, the cushion portion 451 is separated from the seat body 41 and then folded to seal the receiving portion 452, and the excrement can be discarded. In actual implementation, a rope or other sealing structure can also be provided on the receiving portion 452, but it should not be limited to this.

From the above description, it can be seen that the new wheelchair device has the following effects:

1. Reduce the chance of injury: When there is no passenger in the wheelchair device, the riding body 41 is pushed to the first position by the elastic group 51. The first position is higher and can support the weight of the passenger at a higher position. The elastic group 51 can buffer the force of the passenger when riding, which can reduce the probability of the passenger being hit or falling. When the passenger wants to stand up, the elastic force of the elastic group 51 can push the passenger to prevent the passenger from exerting too much force and causing muscle strain.

Second, it can maintain the overall beauty: The cushioning seat 44 can cover the opening 43. When the passenger needs to go to the toilet, the cushioning seat 44 can be moved from the seat body 41 to the back support body 42. When the toilet is finished, the cushioning seat 44 is moved from the back support body 42 to the seat body 41 to prevent others from seeing the opening 43, so as to maintain the beauty of the wheelchair device.

3. Ability to maintain cleanliness: The removable storage bag set 45 is used to store the excrement of passengers when going to the toilet. When the passengers go to the toilet, the pad part 451 is separated from the vehicle body 41, and the pad part 451 is folded to seal the storage part 452. The operation is simple and fast, and no odor is emitted, and the vehicle body 41 can be kept clean.

In summary, the elastic force of the elastic group 51 can push the riding body 41 to a higher first position, and can support the passengers at a higher position. The elastic group 51 can buffer the force during riding and reduce the chance of injury. The elastic group 51 can also generate an upward thrust, making it easier for the passengers to stand up. The blocking structure 52 can limit the rising height of the riding body 41 so that the elastic group 51 can use a stronger spring to provide better buffering and pushing effects. The buffering seat cushion 44 can cover the removable storage bag group 45, and the removable storage bag group 45 can be immediately packed and cleaned after containing dirt, so that the passengers can sit more comfortably, so the purpose of this novel invention can indeed be achieved.

However, the above is only a preferred embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. In other words, simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the description of the present invention are still within the scope of the present patent.
