The present invention relates to a fall prevention safety wheelchair brake device, and more particularly, in a wheelchair having a safety bar for preventing a safety accident due to a fall while moving the wheelchair, to a fall prevention safety wheelchair brake device in which a brake is locked when the safety bar is not fastened, and the brake is switched from a locked state to an unlocked state when the safety bar is fastened.

There is provided a patient transport apparatus. The apparatus includes a height-adjustable assembly having a longitudinal axis. The apparatus includes a brake cable. The brake cable includes an elongate portion extending along the height-adjustable assembly and includes a slack portion. The apparatus includes a brake cable housing coupled to and axially offset from the height-adjustable assembly. The slack portion of the brake cable is enclosed within a hollow interior of the brake cable housing.

A wheelchair brake system comprises: a brake which is provided in a wheel of a wheelchair; and a brake actuation controller which connects with the brake and locks and releases the brake, wherein the brake is usually in a lock mode, but the brake actuation controller controls the brake to be switched over from the lock mode to a release mode if sensing that a user sits down on the wheelchair or the wheelchair is folded up.

The present invention relates to a wheelchair brake assembly comprising a seat brake system and a wheel frame brake system. The seat brake system and the wheel frame brake system are separable from each other. The seat brake system comprises a caregiver brake lever and an actuating member, the caregiver brake lever being coupled to the actuating member. The wheel frame brake system comprises a brake transmission assembly, a first brake mechanism and a second brake mechanism which are adapted to be provided on a first wheel and a second wheel of the wheelchair respectively. The brake transmission assembly is coupled to the first brake mechanism and the second brake mechanism. The brake transmission assembly comprises an actuating lever having a first free end and a second end. The second end is coupled to the first brake mechanism and the second brake mechanism. The actuating lever is rotatable about an axis perpendicular to the longitudinal extension of the actuating lever and located between the first free end and the second end of the actuating lever, wherein the actuating member is adapted to operate on the first free end of the actuating lever to cause the actuating lever to rotate.

A patient transport apparatus includes a height-adjustable assembly having a longitudinal axis, and a brake assembly comprising a brake cable. The brake cable includes an elongate portion extending along the height-adjustable assembly and a slack portion. The patient transport apparatus further includes a brake cable housing coupled to and axially offset from the height-adjustable assembly. The slack portion of the brake cable is enclosed within a hollow interior of the brake cable housing.

A wheelchair suspension comprises a frame, at least one pivot arm, at least one front caster, at least one rear caster, a stabilizing system, and a sensor. The pivot arm is coupled to the frame. The front caster is coupled to the pivot arm. The rear caster is coupled to the frame. The stabilizing system is coupled to the frame and the pivot arm. The sensor is arranged such that tipping of the frame causes actuation of the stabilizing system to at least partially resist further movement of the frame.

An automatic wheelchair locking system including: a first lock for a first wheel; a first persistent driver configured to engage and disengage the first lock; at least one processor configured to control the first persistent driver; and a memory having stored thereon instructions that, when executed by the at least one processor, control the at least one processor to: in response to receiving instructions to disengage the first lock while the first lock is engaged, control the first persistent driver to disengage the first lock; and in response to receiving instructions to engage the first lock while the first lock is disengaged, control the first persistent driver to engage the first lock.

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 sub-mobility device charging system for a vehicle is capable of moving while carrying a sub-mobility device in which a passenger sits. The system includes an acquisition unit, a main electric power supply unit and a controller. The acquisition unit acquires a destination or traveling schedule inputted to the sub-mobility device; the main electric power supply unit supplies electric power to the sub-mobility device carried in the vehicle; and the controller controls to supply electric power to the sub-mobility device via the main electric power supply unit. The controller charges the sub-mobility device on a basis of the acquired traveling schedule for the sub-mobility device in the destination, and generates a traveling route to guide the charged sub-mobility device to a stop-off points corresponding to the destination.
