Description

A new type of standing wheelchair

technical field

The invention relates to a wheelchair, in particular to a novel standing wheelchair.

Background technique

Wheelchairs are one of the main travel tools for paralyzed people, people with disabilities, and frail elderly people. However, most of the wheelchairs currently on the market can only provide sitting postures, and users can only sit in wheelchairs all the time. A single sitting posture leads to The user's buttocks are in a state of compression for a long time, which is prone to bed sores and even atrophy of the leg muscles. There is a new type of standing wheelchair, the principle of which is similar to fixing the user on a vertically placed bed. The whole body of the patient is fixed on the wheelchair, and the muscles of the whole body are still not released. Using these wheelchairs, users often need the help of others to complete daily activities such as exercising, having a meal, washing, going to the toilet, which cannot make the user fully realize self-care. These wheelchairs are only means of transportation for users, and they cannot provide exercise functions for users, and are of little help to users' rehabilitation.

To sum up, the wheelchairs in the prior art cannot allow users to take care of themselves. Therefore, it is necessary to design a wheelchair that can help paralyzed people, people with limited mobility of legs and feet, and frail elderly people to stand freely, so as to realize self-care and exercise rehabilitation. Functional wheelchairs are of great significance.

Preferably, the first binding belt 72a is connected to the buttock support pad 73 through a buckle, that is, the end of the first binding belt 72a is provided with a buckle, and the buckle is buckled in the buckle groove at one end of the buttock support pad 73 to form a detachable connection ; Similarly, the second binding belt 72b is connected to the buttock support pad 73 through a buckle, that is, the end of the second binding belt 72b is provided with a buckle, and the buckle is buckled in the buckle groove at the other end of the buttock support pad 73 to form a Disconnect the connection.

More preferably, the first binding strap 72a is connected to the buttock support pad 73 through a turnbuckle, that is, the end of the first binding strap 72a is tied with a turnbuckle, and the turnbuckle is buckled in the turnbuckle hole at one end of the buttock support pad 73 to form a detachable Flexible connection; Similarly, the second binding belt 72b is connected with the buttock support pad 73 by a turnbuckle, that is, the end of the second binding belt 72b is tied with a turnbuckle, and the turnbuckle is buckled in the turnbuckle hole at the other end of the buttock support pad 73, Form a detachable active connection.

The third driving mechanism 71a and the fourth driving mechanism 71b respectively drive the first binding belt 72a and the second binding belt 72b to tighten or loosen the buttock support pad 73, so that the hip support pad 73 can support the user's buttocks, further stabilizing The user's standing posture is improved, the user is prevented from squatting, and the comfort of the user is also improved.

As shown in Figure 4, the user can operate the wheelchair 100 to switch between the sitting posture and the standing posture. 53 and hip support pad 73, then place hip support pad 73 below the buttocks and connect waist support 53 to the ends of the first telescopic swing arm 52a and the second telescopic swing arm 52b from behind the waist.

Secondly, the user puts both feet on the pedal 14, and at the same time twists the integrated controller 43 to control the reverse rotation of the third drive mechanism 71a and the fourth drive mechanism 71b, thereby shortening the first binding belt 72a and the second binding belt 72b to Properly position and make the buttock support pad 73 close to the user's buttocks, and further put the calf or knee against the "U" shaped groove of the first knee support 6a and the second knee support 6b, while the user grasps the handle with his hand 32.

Finally, the user presses the second drive mechanism controller 33 with the thumb of the right hand to control the second drive mechanism 54 to push the "T" shaped transmission shaft 54b to rotate and drive the first telescopic swing arm 52a and the second telescopic swing arm 52b to swing upward. The arm movement drives the waist support 53 and the buttock support pad 73 to support the user's waist and buttocks, thereby completing the user's movement from a sitting position to a standing position and maintaining the standing position continuously. 43 Control the first drive mechanism 15 to drive the front wheel assembly 12 to make the wheelchair 100 of the present invention move forward, and the user can drive the wheelchair 100 to realize operations such as forward, backward and turning. In addition, the first drive of the wheelchair 100 of the present invention The mechanism 15, the second driving mechanism 54, the third driving mechanism 71a and the fourth driving mechanism 71b can all realize the self-locking function when they are in the stopped state, thereby effectively ensuring the personal safety of the user.

When the user does not use the wheelchair 100, he only needs to press the second drive mechanism controller 33 with the thumb of his right hand to control the first telescopic swing arm 52a and the second telescopic swing arm 52b to produce downward swing arm movement, and simultaneously Under compression, the first telescopic swing arm 52a and the second telescopic swing arm 52b are gradually shortened, and the waist support 53 and the buttock support pad 73 will also slowly swing downwards. Finally, the user slowly changes from a standing posture to a sitting posture, and from a standing posture Release your right thumb after you are in a sitting position. Further, the integrated controller 43 can be twisted to control the third driving mechanism 71a and the fourth driving mechanism 71b to make the buttock support pad 73 in a relaxed state so that the buttock support pad 73 can be removed, and the lower leg can be lifted from the pedal after the waist support 53 is removed. Board 14 is taken down, can break away from wheelchair vehicle 100.

In summary, the user can freely switch between sitting and standing postures by driving the wheelchair 100 of the present invention, and the user can complete daily activities such as cooking, dining, and going to the toilet on the wheelchair 100, so as to realize self-care . After the user is fixed on the wheelchair 100, he can also sit down and stand repeatedly by means of the auxiliary standing mechanism, and do simple rehabilitation squat training for the legs. Finally, a novel standing wheelchair 100 of the present invention has the advantages of ingenious design, compact structure, simple operation, safety and stability.
