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.

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.

A wheelchair apparatus is provided for raising and lowering a user of the wheelchair, while allowing the user to manually move the wheelchair at any height.

A small electric vehicle includes: a vehicle body that has a forward and backward direction, and a width direction; left and right driving wheels provided apart in the width direction of the vehicle body; left and right motors connected so as to respectively transmit power to the left and right driving wheels; an operation unit that includes a joystick-type operation piece; and a control unit for controlling the left and right motors according to an amount of operation on the operation piece, wherein the control unit is configured to execute deceleration and stop control when the operation piece is returned to the neutral position during travel, and execute rapid stop control irrespective of an amount of operation in left and right directions when the operation piece is tilted backward during forward travel at a speed equal to or greater than a predetermined threshold.

A wheelchair comprises a frame and two main wheels each coupled to a hand rim for actuating the wheels in both directions of rotation and for braking.

The present invention relates to a wheelchair improvement kit and a manual wheelchair. The improvement kit includes an anti-tip device including a pair of multifunction tube assemblies. Each multifunction tube assembly includes a mount tube configured for pivotally mounting one on each side of the wheelchair, a slide tube slidably engaged to the mount tube where both ends of the slide tube extend beyond the mount tube, a slide tube brake engaging or releasing the position of the slide tube relative to the mount tube, and an extendable pole inserted into the top of the slide tube. The top of the extendable pole is fitted with a hand grip. The anti-tip device further includes a pair of guide tubes configured for mounting one on each side of the wheelchair. When the multifunction tube assembly is used as the anti-tip device, the slide tube passes through the guide tube.

An apparatus includes a frame assembly configured to be selectively connectable with a seat assembly of a wheelchair assembly once the seat assembly is selectively disconnected and removed from the wheelchair assembly. The frame assembly is also configured to be selectively connectable with spaced-apart wheel assemblies of the wheelchair assembly once the spaced-apart wheel assemblies are selectively disconnected and removed from the wheelchair assembly.

A brake actuation mechanism for a human powered mobility device, such as a lever drive wheelchair, is described. The brake actuation mechanism may include an actuator member positioned at or near an end of a lever drive such that the actuator member may be actuated or engaged by a user's thumb when grasping a lever of the human mobility device. Since the lever may drive motion of human mobility device, the user may maintain a firm grip on the lever while also manipulating or engaging the actuator member.

A small electric vehicle includes: a vehicle body that has a forward and backward direction, and a width direction; left and right driving wheels provided apart in the width direction of the vehicle body; left and right motors connected so as to respectively transmit power to the left and right driving wheels; an operation unit that includes a joystick-type operation piece; and a control unit for controlling the left and right motors according to an amount of operation on the operation piece, wherein the control unit is configured to execute deceleration and stop control when the operation piece is returned to the neutral position during travel, and execute rapid stop control irrespective of an amount of operation in left and right directions when the operation piece is tilted backward during forward travel at a speed equal to or greater than a predetermined threshold.

A wheel brush for a wheelchair has a brush assembly that is slidably disposed within a main housing and biased therein via a spring. A brush head is held within one end of the brush assembly so that a portion of the bristles of the assembly extend beyond an open end of the main housing. The device is attached to a brake arm of the wheelchair via a mount member that has a channel such that the brake arm is received within the channel. The wheellock assembly pushes the device toward a rear wheel of the wheelchair such that the bristles engage the wheel and brush dirt off the wheel as the wheelchair rolls being biased thereonto by the spring. The mount member acts as the brake arm for the wheelchair.
