A wheelchair comprising a seat back, a seat bottom, a frame, two front wheel assemblies, two drive wheels, two wheelchair wheels, and an anti-rollback wheelchair braking system consisting of two braking units, each unit comprising a housing cylinder body cap, a housing cylinder body, a housing cylinder mounting assembly, a wheelchair mounting assembly, rotatable toggle clamp direction selection lever, an anti-rollback, one-way, brake assembly, and a toggle clamp assembly for engaging the said anti-rollback, one-way, brake assembly with a wheelchair wheel. A parking brake assembly may also be included. The invention may be manufactured and sold as a whole wheelchair assembly or a retrofit kit for standard wheelchairs.

Wheelchair egress system

The present invention provides an assembly having a wheelchair and a lift assembly to urge the seat surface upward with respect to the frame from a lowered position when supporting the seated individual during use to an elevated position with respect to the frame assisting the individual during ingress or egress to or from the wheelchair. The lift assembly may include a mechanical linkage and an actuator. The assembly also provides at least one brake configured to block rotation of the wheelchair wheel with respect to the wheelchair frame in a locked state and disengaging with the wheels to allow rotation of the wheel with respect to the frame in an unlocked state. The assembly also provides a brake linkage communicating between the lift assembly and the brake to move the brake into the lock state when the seat surface moved to the elevated position.

Anti-rollback mechanism for a wheelchair
11628104 · 2023-04-18 ·

An anti-pushback mechanism for a wheelchair provides for a side mounted lever to allow the wheelchair to move in a forward motion only, a rearward motion only, or a neutral position where it can be pushed in any direction. This lever is connected to a ratcheting style gear that stops rollback when engaged. A torsion spring moves the chair forward slightly as the user stands to keep the chair close to the user and prevent falling. The invention may be provided as an add-on kit for existing wheelchairs. The kit would consist of a center axle, the ratchet gear, the torsion spring, the crossbar frame, the actuating lever, a guard for the lever, and any associated clamps and fasteners.

Hand Propelled Wheeled Vehicle

A hand propelled wheeled vehicle, specifically a wheelchair, containing a pair of hand actuated, lever driven mechanisms to rotate the main wheels. The levers pivot around attachment points on the left and right sides of the vehicle chassis. The left lever actuates a frame responsible for contra-rotating two integral one-way clutches arranged on a drive shaft coupled to the left main wheel, with the right lever operating the right side mechanism in an identical fashion. The arrangements of the clutches utilize both the forward (pushing) and backward (pulling) stroke of the lever to rotate the main wheels forward. Steering and braking control is afforded through attachments integral to the hand grips of the right and left hand levers, respectively.

SYSTEM TO ADJUST DRIVE OPERATION AND PERFORMANCE IN RESPONSE TO DETECTION OF A FRONT ADD-ON FOR A WHEELCHAIR

A wheelchair including a steering assembly configured to selectively attach to the wheelchair, the steering assembly including a steering member, a front wheel operably connected to the steering member, a frame assembly configured to carry the steering member and the front wheel, and a mounting assembly coupled to the frame assembly, and a drive assembly coupled to the wheelchair. The drive assembly is configured to operate in a first configuration in response to the steering assembly being detached from the wheelchair, and the drive assembly is configured to operate in a second configuration in response to the steering assembly being attached to the wheelchair.

HANDLE COVER APPARATUS

DETECTING ACTIVITY BY A WHEELCHAIR USER

The present disclosure relates to a system and method of detecting activity by a wheelchair user. In one aspect, a method comprises collecting motion data of a user device located on an appendage of the user; detecting, by a processor circuit, that one or more activities by the wheelchair user occurred based on the motion data; calculating, by a processor circuit, an energy expenditure by the user based the one or more activities by the wheelchair user occurred; and outputting, by a processor circuit, the energy expenditure estimation.
