The above case can also cause the wheelchair to move laterally. However, the user must replace the old wheelchair with the entire wheelchair. Therefore, the high cost cannot be widely used by a large number of wheelchair users, and the installation of a large number of multiple rolling wheels will increase. The weight of the wheelchair itself may cause a burden on the use when it is pushed, which is more laborious and inconvenient.

Therefore, in order to improve the above-mentioned deficiencies, the present invention provides a wheelchair lateral movement assisting device for coupling to a wheel body of a wheelchair, the wheelchair laterally moving assistor structure comprising: a frame body, detachably coupled to the wheel The frame body includes two clamping portions for relatively clamping the two sides of the wheel body; at least one rolling portion is disposed on the frame body to pass through the at least one rolling portion when the frame body supports the wheel body The wheelchair is displaced laterally.

Wherein, the rolling portion comprises a universal ball.

Wherein, there is a spacing between the two clamping portions, the spacing is slightly smaller than a width of the wheel body, and the wheel body is deformed by the elastic insertion of the wheel body to be deformed by the two clamping portions. Tightly fixed.

Wherein, one side of the wheel body has a hand wheel, and a connecting rod is arranged between the hand wheel and the wheel body, and at least one of the clamping portions is provided with a fixing portion for detachably fixing on the connecting rod.

The fixing portion of the clamping portion is an engaging groove.

Wherein, the clamping portion has two wall surfaces adjacent to the engaging recess, and the two wall surfaces have a spacing therebetween, the spacing corresponding to a diameter of the connecting rod for the connecting rod to be locked.

The frame body further includes at least one blocking lever, and the at least one blocking lever is connected to the two clamping portions, and the blocking lever is configured to block the wheel body.

Further, the frame body is provided with two supporting portions corresponding to the two clamping portions, and the rolling portion is disposed between the two supporting portions.

A method of using an auxiliary device configuration for laterally moving a wheelchair as described in claim 1 of the patent application, comprising the steps of: A. fixing the fixing portion of the frame body to the wheel body; B. controlling the wheel body to rotate, so that the support portion of the frame body contacts a ground to prop up the wheelchair; C. continuing to rotate the wheel body, so that The plurality of rolling portions contact the ground, and the wheelchair generates lateral displacement by the plurality of rolling portions.

The effect of the invention is:

1. The present invention is detachably mounted on a wheel body of a wheelchair through a frame body provided with a rolling portion, so that the wheelchair is laterally displaced, and when the user is in a small space and is inconvenient to push the wheelchair, the invention can be quickly locked in the wheelchair. The wheel bodies on both sides are deformed by relatively clamping the wheel body, and then pushed to the ground to stand up the wheelchair, so that the rolling portion can be freely moved freely, and it is convenient to disassemble without lateral displacement.

2. The invention is detachably fastened to the connecting rod between the handrail of the wheelchair and the wheel body through the fixing portion, and the fixing body is provided on both sides of the frame body to assist the fixing to the wheel body, so the device is installed When the wheel body on both sides of the wheelchair is used, it is not necessary to consider fixing to the left or right side of the wheelchair, and the frame body is prevented from shifting off when the wheel body is rotationally displaced.

3. The invention is small in size, light in weight, convenient to carry and generally applicable to wheelchairs, so that the function of adding lateral displacement can be additionally added without replacing the original wheelchair.
