The present invention relates to a wheelchair footrest 1, comprising a continuous foot support 10 or two separate foot supports 10 for supporting the feet of a user; and at least one lighting means 20; wherein said lighting means 20 is fixedly arranged on at least one of said foot supports 10 to illuminate at least a floor area 40 on a front side 102 of said wheelchair 100; and the lighting means 20 comprises an LED strip which is fixedly arranged on the underside 12 of the at least one foot support 10, and wherein the LED strip has a length BL which extends over at least 50% of the width B of the at least one foot support 10. The present invention relates also to a wheelchair 100 comprising a corresponding wheelchair footrest 1.

Provided is a wheelchair that can be operated easily with either a right or left hand. The wheelchair is provided with; right and left handrims; a rotary shaft for transmitting a rotational force generated by a handrim on one side to a wheel on the opposite side via a drive mechanism; and a wheel hub for transmitting the rotational force generated by the handrim on the one side to the wheel on the same side via the drive mechanism, wherein the drive mechanism includes two pairs of right and left sensors respectively disposed on an outer surface of each of the handrims, a first non-excitation electromagnetic clutch for transmitting the rotational force to the right wheel, a second non-excitation electromagnetic clutch for transmitting the rotational force to the wheel on the opposite side, and a third non-excitation electromagnetic clutch for transmitting the rotational force to the left wheel.

A wheelchair having a frame and a drive wheel coupled to the frame. The drive wheel rotates relative to the frame about a first axis of rotation. A first push rim is coupled to the frame. The first push rim rotates relative to the frame about a second axis of rotation that extends substantially parallel to the first axis of rotation. A second push rim is coupled to the frame. The second push rim rotates relative to the frame about a third axis of rotation that extends substantially parallel to the first axis of rotation. A transmission transmits rotation of each of the first and second push rims to the drive wheel. Movement of the first push rim by a first arc length causes the drive wheel to rotate by a first angular displacement, and movement of the second push rim by the first arc length causes the drive wheel to rotate by a second angular displacement that is greater than the first angular displacement.

Provided is a lightweight and inexpensive wheelchair that can be easily operated with either a right or left hand. The wheelchair according to the present invention is provided with; a pair of handrims having a first portion connected to each handrim spoke and a second portion connected to a base of each wheel; a drive mechanism for transmitting a first rotational force generated by the first portion on one side and/or another side to the wheel on the one side and the wheel on the other side, wherein the drive mechanism includes an axle on the one side, an axle on the other side connected to the axle on the one side via a rotary shaft, a first two-way clutch located on the axle on the one side, and a second two-way clutch located on the axle on the other side.

A wheel assembly comprising a wheelchair wheel (5) and a backstop arrangement (10; 30; 70) configured to selectively engage and disengage a backstop function and comprising a backstop selector (15; 35; 75) and a backstop member (18; 38; 78), wherein the wheel (5) comprises an internal-gear wheel hub (11; 31; 71) comprising a number of internal gears (57, 58) and having an inner rotatable circumferential surface (13; 33; 73), and wherein the backstop member is configured to allow the inner circumferential surface to rotate in one direction and to prevent rotation in the opposite direction. The wheel assembly comprises further a gear-shift arrangement comprising a shift member (54), which is axially moveable within the internal-gear hub (31) to engage a specific gear of said number of internal gears (57, 58), and wherein the shift member (54) via a connector member (55) is operatively connected to the backstop selector.

A reciprocating drive motion wheelchair is provided. The wheelchair device includes a low-profile wheelchair that utilizes push bars pivotally connected to the wheelchair frame and operably connected to a crank bar, which run parallel to the ground and connects back to a crank on each wheel. An additional pair of wheels is disposed rearward of the drive wheels and prevents the wheelchair from tipping, thus allowing the user to utilize the push bars to move the wheelchair quickly and easily.

An apparatus for facilitating user propulsion of a wheelchair having a frame for supporting a user and a pair of rear wheels that rotate about an axis. The apparatus includes a handgrip having an outer surface and an opposite, inner surface such that when a radial force relative to the axis is applied to the outer surface by the user the inner surface is configured to engage a rear wheel in the pair of rear wheels such that the rear wheel can be rotated and the wheelchair propelled. A pair of coupling members configured to couple the handgrip to the frame and hold the handgrip in a neutral position, and the pair of coupling members are further configured to alternately increase in length and become tensioned as the user moves the handgrip away from the neutral position to rotate the wheel.

A mobile chair apparatus is described that comprises a drive assembly that preferably includes one or more moveable foot pedals, and drive wheels which rotate in response to rotation of the foot pedals by the mobile chair occupant, and a steering assembly which comprises two steering wheels and at least one tiller, configured such that forward and backward movement of said tiller will translate into movement of both steering wheels, wherein the drive assembly and the steering assembly concurrently enable the mobile chair occupant to propel and steer the mobile chair apparatus without assistance from another person.
