Description

wheelchair

The present invention relates to a wheelchair, especially an openable and closable wheelchair.

Wheelchairs are means of transportation for people with reduced mobility. Most of the current wheelchairs can be folded, but there are problems that cleaning is not easy and the use is too single.

For example, for some users, it is necessary to purchase a wheelchair and a toilet device at the same time, which not only occupies space, but also requires the assistance of others to switch between the two, which is very inconvenient.

The present invention provides a wheelchair with the advantages of convenient cleaning and multifunctionality.

The wheelchair provided by the present invention includes a seat frame, two bottom plates, two armrest frames, two seat back frames, a pair of auxiliary pipes and a pair of handles. The chair frame includes a bottom frame and a pair of telescopic main rods. The bottom frame includes a front cross rod.

The wheelchair according to an embodiment of the present invention further includes two front wheels and two rear wheels connected to the chassis. The wheelchair further includes two brake assemblies. Each brake assembly includes a brake lever disposed on one of the handlebars, a brake connected to one of the two front wheels, and a brake wire connected between the brake lever and the brake.

The wheelchair according to an embodiment of the present invention further includes a locking mechanism. The locking mechanism includes two locking pieces, a locking block and a locking pin. The two locking pieces are arranged on one of the two seat back frames and are opposite to each other. The locking block is disposed on the other one of the two seat back frames and is suitable for being located between the two locking pieces when the two seat back frames are closed. The locking pin is adapted to pass through the two locking pieces and the locking block.

The wheelchair according to an embodiment of the present invention further includes two seat back pads and a buckle mechanism. The two seat back cushions are respectively connected to the two seat back frames, and are also suitable for opening and closing relative to the rotation of the two upper tubes relative to the two lower tubes.
