Various implementations include a wheelchair traction attachment device. The device includes a frame having an arcuately-shaped longitudinal axis, an inner surface, an outer surface opposite and spaced apart from the inner surface. The frame has a first edge extending between the inner and outer surfaces, and a second edge spaced apart from the first edge. At least a portion of the inner surface defines a channel. The device includes at least one first wheel-clip extending radially inwardly from the first edge of the frame relative to the arcuately-shaped longitudinal axis. The device includes at least one second wheel-clip extending radially inwardly from the second edge of the frame relative to the arcuately-shaped longitudinal axis. The device includes a traction portion disposed along at least a portion of the outer surface, the traction portion extending radially outwardly from the outer surface relative to the arcuately-shaped longitudinal axis.

A personal mobility device includes a control system including a manually operated actuator, a first forward control valve having an inlet in fluid connection with a source of pressurized gas and an outlet in fluid connection with a first forward port of at least a first pneumatic motor, and a first rearward control valve having an inlet in fluid connection with the source of pressurized gas and an outlet in fluid connection with a first rearward port of the first pneumatic motor. Movement of the manually operated actuator controls actuation of the first forward control valve and the first rearward control valve and thereby flow of gas from the source of pressurized gas to the first forward port and the first rearward port.

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.

The present disclosure describes a system and method for a providing an assistive driving force to a wheelchair.

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 wheelchair W includes: a column shaft (50) extending from the rear portion of a front fork (51) and turnably supported by a vehicle-body frame (2); a rocking bar (81a) that is rockably attached to the vehicle-body frame (2) and rocks according to a force applied by a rider; and a link mechanism (82) that joins the rocking bar (81a) and the column shaft (50) and turns the column shaft (50) according to rock of the rocking bar (81a).

A standing training mobile device for carrying a patient to perform active-assisted upright locomotion is provided. The standing training mobile device includes a base, a mobile module, a lifting module, a control module, and a support module. The mobile module and the lifting module are disposed on the base. The control module is disposed on the lifting module and is coupled to the mobile module. The control module includes a manipulation platform and two control assemblies disposed on the manipulation platform for use of the patient. The support module includes a support frame, a first support assembly, a second support assembly, and a third support assembly. The first support assembly, the second support assembly, and the third support assembly are slidably disposed on the support frame respectively. The second support assembly is disposed between the first support assembly and the third support assembly.

A transmission apparatus for a leveraged wheelchair may include a wheelchair, a driving mechanism, a driving wheels set, and a transmission wheels set. The driving mechanism has a first tube and a second tube which are pivotally connected, and with the relative movements between the first tube and the second tube, the driving wheels set can have forward or rearward rotation so as to achieve bi-direction driving effect of the wheelchair. Also, the relative movement between the first tube and the second tube is cooperated with a flexible connecting head such that a handle of the wheelchair is adapted to be forward and rearward pulled or rotated axially so to achieve the moving and turning actions of the wheelchair with one hand.
