Description

Wheelchair construction with rehabilitation function and rehabilitation component thereof

The present invention relates to a wheelchair, and more particularly to a wheelchair construction having a rehabilitation function and a rehabilitation assembly thereof.

Wheelchairs are used to assist users who have a bad foot. In order to allow the user to rehabilitate when riding a wheelchair, the user's foot bones can be restored. At present, there are wheelchair research and development such as the Republic of China new patent announcement No. M374345 "Wheelchair", the Republic of China invention patent announcement number I320314 "Reflexive wheelchair transmission mechanism (1)" and I320315 "Rehabilitation wheelchair transmission mechanism (2) "Wait.

The wheelchairs are mainly provided with a pedaling linkage mechanism, so that the pedals can be moved with the displacement of the wheelchair to assist the user in performing rehabilitation exercises on the wheelchair. However, in order to facilitate the user to rest at a proper time, the pedaling linkage mechanism needs to cooperate with a complicated transmission mechanism and a clutch mechanism, so that the overall weight of the wheelchair is too heavy, which is unfavorable for the user to promote the wheelchair activity and also cause the care worker. The burden, on the other hand, will also result in higher product cost.

Another manufacturer has developed a new type of patent publication No. M390136 of the Republic of China, "a wheelchair with an auxiliary rehabilitation device", which is mainly integrated with an auxiliary wheel contacting the ground in front of the wheelchair body, and the auxiliary wheel is combined with a pedal to When the wheelchair body moves, the auxiliary wheel is rotated together to drive the pedal to rotate to assist the user's foot movement. However, when the auxiliary wheel of the previous case touches the obstacle or the ground level is high and low, it is easy to cause the wheelchair to shake, which affects the comfort of the ride.

Accordingly, in order to allow the user to perform rehabilitation while riding a wheelchair without affecting the comfort of the ride, the inventors propose a rehabilitation component for a wheelchair for assembly in a wheelchair having a pair of wheel bodies. Each of the pair of wheel bodies has a rotating shaft, and the rehabilitation component comprises: a driven member coupled to one side of one of the wheel bodies of the wheelchair, wherein the one of the wheel bodies rotates with the rotating shaft as an axis, and the driven member has At least one joint portion, the at least one joint portion and the rotating shaft have a spacing in a radial direction of the one of the wheel bodies; a rod is detachably coupled to the wheelchair; and a linkage rod is erected on the rod, The linkage rod has a joint end and an actuating end, and the joint end is pivotally connected to the joint portion of the follower member, so that the linkage rod is swung by the driven member, and the movable end of the linkage rod is reciprocally displaced.

Further, one side of the pair of wheel bodies has a push wheel frame, and the follower is detachably coupled to the hand wheel frame.

Further, one side of the pair of wheel bodies has a push wheel frame, and the follower is detachably coupled to the hand wheel frame.

Further, the follower has a plurality of fasteners centered on the rotating shaft, and each of the fasteners and the follower are connected to each other by an elastic member, so that each fastener is detachably fastened to the hand Push the wheel box.

Further, the mast has a clamp for being clamped to the wheelchair.

Further, the pole has a stop corresponding to the linkage.

Further, the actuating end of the linkage rod is combined with a roller or/and a treading member.

Further, the actuating end of the linkage rod is combined with a ring, and the upper ring of the ring is provided with a plurality of rollers.

Further, the at least one joint portion of the follower member is a pivot hole, and the joint end of the linkage rod is pivotally correspondingly pivoted to the pivot hole, and the pivot shaft is provided with a buckle portion corresponding to the slave movement Pieces.

Further, the follower is provided with a plurality of joints in the radial direction, so that the joint end of the linkage rod is selectively pivoted to one of the joint portions.

The present invention is also a wheelchair construction having a rehabilitation function, which uses the aforementioned rehabilitation component of a wheelchair, the wheelchair structure having a rehabilitation function comprising: a wheelchair having a pair of wheel bodies; and a rehabilitation component detachably Combined with one side of one of the wheelchairs.

The invention has the following effects:

1. The rehabilitation component of the present invention is driven by the wheel of the wheelchair, and since it does not need to touch the ground during use, the balance of the wheelchair movement can be avoided by the rehabilitation component, thereby improving the comfort of the wheelchair.

2. The rehabilitation component of the present invention is simplified in order to assist the user's rehabilitation as much as possible without increasing the overall volume and weight of the wheelchair.

3. The rehabilitation component of the present invention can be combined with an existing wheelchair to prevent the user from having to replace the existing wheelchair, and the user does not need to purchase the rehabilitation component again when replacing the wheelchair to lower the product. The cost of use.

4. The rehabilitation component of the invention can be removed from the wheelchair when it is not needed, so that the user can flexibly disassemble according to his own needs, and the product has high practicability.

5. The rehabilitation component of the present invention can adjust the displacement stroke of the actuation part by combining the linkage rod with different positions of the follower according to the rehabilitation needs of different users, and the product suitability is good.
