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.

A brake for a trolley that can brake rotation of a trolley wheel only in one direction. The brake includes a support connectable with a frame of the trolley, a first axle connected with another end of the support and peripherally provided with three indents, a pivotal first handle with a detent, wherein the first handle on the first axle can assume three positions defined by the three indents, a pin connected with the first handle and arranged parallel to the first axle, an eccentric ring with a recess, through which the pin projects, wherein the eccentric ring is pivotally mounted on the first axle and can engage with the outer periphery of the pulley wheel, a tension spring connecting the inner periphery of the eccentric ring and the pin, and a stop element projecting from the first axle, which can lean against the inner periphery of the eccentric ring. The brake enables unidirectional braking of a trolley either in forward movement or in rearward movement.

A brake assembly for a manually-operated, height-adjustable wheeled vehicle according to a first aspect includes a brake cable assembly. The brake assembly includes a brake cable housing shaped to enclose an excess portion of the brake cable assembly. The brake assembly includes a cable adjuster coupled to the brake cable assembly. The cable adjuster is enclosed by the brake cable housing. There is additionally provided a wheel fork assembly for a manually-operated, height-adjustable wheeled vehicle according to a first aspect. The vehicle includes a frame member. The wheel fork assembly includes a mount shaped to couple with a lower end of the frame member of the vehicle. The mount has a longitudinal axis. The wheel fork assembly includes a wheel fork having a longitudinal axis offset from the longitudinal axis of the mount. The wheel fork is integrally coupled to and formed with the mount.

A wheeled nursing and medical device includes a wheeled seat mechanism, a driving module, a bed mechanism and a linking mechanism. The wheeled seat mechanism includes an expandable base frame and front and rear wheel assemblies. The driving module is operable to drive expanding and retraction of the expandable base frame. The bed mechanism includes a main bed plate and a backrest plate pivotally connected with the main bed plate. The linking mechanism includes at least one inclined bracket pivotally connected with the expandable base frame and the backrest plate. The device is shiftable between a bed state and a wheelchair state to render traveling of the device in the wheelchair state convenient.

A gravity reactive braking system comprises a housing connected to a structural element of a manually powered wheeled unit; a guide wheel having a first sector of radially protruding elements positionable in drivable contact with a main wheel periphery, and a second sector with a circular periphery of a shorter radial length than the first sector; a plate configured with a cammed surface; a height adjustment unit; and a follower element connected to a brake assembly cable and pivotably mounted onto the housing, for movably engaging a plate periphery. The guide wheel is rotatable in a rotational direction opposite to the main wheel's rotational direction when the radially protruding elements are positioned in drivable contact with the main wheel periphery following suitable manipulation of the height adjustment unit, and is indexable a predetermined angle until a desired region of the guide wheel is in contact with the main wheel periphery.

A manual movable body with wheels 10 which can be moved by manually rotating the wheels, comprising an upper body frame 12 supporting a heavy goods, a pair of travelling wheels 18, each of which is provided on the corresponding side of a lower body frame 14 which is not in contact with upper body frame 12, and is rotationally supported by a first horizontal rotation shaft 16 extending in the widthwise direction of the lower body frame 14, and a pair of abutting rollers, each of which is mounted on upper body frame 12, and is rotationally supported by a second horizontal rotation shaft extending in the widthwise direction of the upper body frame 12.

A wheelchair anti-rollback device utilizes one-way roller clutches which incorporate a selectable free-rotation functionality such that the wheelchair user can select between anti-rollback and free-wheeling modes. The anti-rollback mode is of utility when the wheelchair user is propelling up ramps. The modal selection is by means of a knob positioned on the centerline rotation axis of the mechanism. The mechanism also included functionality that allows mode change from anti-rollback to free-wheeling to be made at any time, including while the chair is on an inclined ramp. The invention can incorporated into the hub of the rear wheels of a wheelchair or into the toggle mechanism of typically used to actuate parking brakes. When incorporated into a wheelchair, the invention gives the wheelchair user greater control and ease in ascending ramps.

A wheelchair that prevents the secondary transmission of germs, including a seat, a drive mechanism, antibacterial fabric, and a dirt-retaining board. The drive mechanism is symmetrically provided about the seat. The drive mechanism includes a frame, front wheels, rear wheels, and drive wheels. The frame is fixedly connected to the seat. The front wheels, the rear wheels, and the drive wheels are all rotated and set on the frame. The drive wheels are not coaxial with the front wheels and rear wheels and do not interfere with each other. Drive wheels are connected to the rear wheels by transmission. The dirt-retaining boards are installed on the rear wheels in coordination. The active wheels, the seat, the armrests, and the push handles are sleeved thereon with antimicrobial fabric.

A wheelchair including a transparent frame including a first side panel, a second side panel, a back section between the first and second side panels, and a seat section between the first and second side panels, a plurality of wheels rotatably coupled to the frame, and at least one handle coupled to the frame, wherein the wheelchair is entirely nonmetallic.
