Problems solved by technology

[0005] At the same time, there are also some defects in ordinary wheelchairs, especially when the disabled in the wheelchair will go uphill, they need to use their hands to provide a larger moment of driving the wheels.
[0006] In addition, it is especially difficult when a disabled person in a wheelchair encounters a bump when going uphill, because the bump on the slope will cause the wheelchair to fall backwards

Embodiment Construction

[0019] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] figure 1 is a schematic diagram of a wheelchair driving device according to a preferred embodiment of the present invention.

[0021] The device for driving the wheelchair includes a first roller 40 and a central axis support 20, one end of which is aligned with the central axis 14 of the wheel, and the other end is mounted on the armrest 13 of the wheelchair.

[0022] In addition, one end of the lever 30 is inserted and mounted on the wheel center shaft 14 so that the lever 30 can rotate around the center shaft 14 .

[0023] A bracket 60 for supporting the second roller 70 is also connected to the central shaft 14 for rotation.

[0024] The bracket 60 of the second roller 70 is also connected to a bracket 90 with a clamping portion 100 .

[0025] One side of central axis support 20 has just become a hinge now. The clamping part 100 ...

Abstract

An apparatus for propelling the wheelchair that prevents a backward movement and helps the occupant rotate the wheel with less manual torque. The invention makes it possible for the disabled person to climb the sloped road with less manual force and without fear of dangerous backward slide.

Description

technical field [0001] The invention relates to a wheelchair, in particular to a device for driving the wheelchair. More specifically, the present invention relates to a wheelchair with a manual drive that allows the wheelchair user to drive the wheelchair with less torque and even to go up slopes with ease. Background technique [0002] A typical wheelchair consists of a seat frame mounted between two pairs of front and rear wheels. The person in a wheelchair drives the wheelchair directly by driving the rear wheel by hand. [0003] A disabled person sitting in a wheelchair can make the driving wheel rotate by pushing the wheel rim coaxially installed with the driving wheel if he wants to go somewhere. [0004] For example, US Pat. Nos. 6,112,837 and 6,095,747 both disclose technology for wheelchair devices for disabled persons. [0005] Simultaneously, there are also some defects in common wheelchairs, especially when a disabled person sitting in a wheelchair will go up...
