TH18643B - Self-standing adjustable wheelchair - Google Patents

Abstract

DC60 (28/01/48) This self-standing adjustable wheelchair. Is a craft that can be used with More patients with different types of paralysis were assembled by using two 4,5 gas springs with uneven pressure. The connecting triangle 6 is the power system, then it is installed between seat 1 and car frame 10 that make up the 4-piece linkage mechanism by installing in the position suitable for the patient's body weight. Changing from a sitting position to a standing position and from a standing position to a sitting position can be done comfortably without the patient. Enough arm strength is needed to push yourself up to beat the first 30 degrees of standing up. In addition, the 8,8 handle can be adjusted independently to the right position. Regardless of changing the position of the seat 1, the 8,8 handle can be adjusted to give the elbow extension advantage using the early range of elbow extension, which requires less force. Promoting the footrest 14 using the tether 15 allows the body weight to be transferred through the foot to the The floor is faster, as a result, making it easier to stand up and sit down.

Claims (1)

1. A wheelchair that can be adjusted to stand on its own has the characteristics of part of wheelchair, handicapped person, and part of standing device The wheelchair part consists of the car frame (10), the seat (1), linkage (3), which are assembled into four mechanisms. The backrest (2) is attached to the linkage (3) in such a way that when the seat ( 1) Change the position from sitting to standing. The angle of the backrest (2) to the seat (1) is changed from 90 degrees to 180 degrees. The footrests (14) are attached to the car frame (10) in such a way that they can be moved up and down. Along the axes (20) that make up the frame (10) and footrests (14) are connected to the seat (1) by linkages (15), making the up and down movement of the footrests ( 14) along the axis. (20) as part of the frame (10) is controlled by the movement of the seat (1) through the linkage (15) part of the stand. It consists of a power system for adjusting the position from seat to stand. Mounted between the seat (1) and the car frame (10), the power system consists of a connecting triangle (6) and two gas springs, a gas spring (4) and a gas spring (5), a handbrake (7), 7\') for controlling the work of Gas spring (4,5) mounted on handle(8,8\'), handle(8,8\') mounted on seat(1). The characteristics are 1.1 power system for adjusting the position from sitting to standing. It consists of a connecting triangle (6) and two lockable gas springs, a gas spring (4) and a gas spring (5). A connecting triangle (6) is two triangular steel plates of different sizes and positions. Exactly the same holes are fixed. parallel with latch The acute (smallest) hole is secured to the seat (1) so that the connecting triangle (6) can rotate smoothly around the mounting point. One end of the gas spring (4) is fastened to the connecting triangle (6), while the other end is fixed to the seat (1). Each end of the gas spring (4) can rotate smoothly around the mounting point. One end of the gas spring (5) is attached to the frame (10) and the other end is attached to the connecting triangle (6) in a hole position suitable for the patient's weight range. Each end of the gas spring (5) can easily rotate around the mounting point. 1.2 Links (15) link between the footrest (14) and the seat (1) consist of two cylinders. which can be worn together and can slide in a limited distance When sliding to the end of the distance (longest) both cylinder The two will be locked away from each other. One end of the connector (15) is attached to the seat (1), the other end of the docker (15) is attached to the footrest (14). spontaneous The operation of the linkage (15) allows the footrest (14) to quickly touch the ground when the seat (1) is repositioned. The angle with the frame (10) is approximately 30 -45 degrees. As a result, most of the body weight is transferred to the ground. It is easy to set up, stand up and look stable. and from the technique of controlling the gas springs to work one by one (as described in the method Adjusting the position from standing to sitting) in conjunction with the work of the jigsaw (15) makes it possible to adjust from standing to sitting. easy as now 1.3 The handle (8,8\') has a fixed locking mechanism that controls the release with a button (9,9\') at the end of the handle (8,8\'). in the right position Independent of repositioning of the seat 1, the handlebar (8,8\') can be adjusted to give the advantage of elbow stretching.
