摘要： A device including a frame; an actuator attached to the frame and slidaby movable with respect to the frame along a linear axis, and a helical member positioned within the frame and rotatably movable with respect to the frame about a helical axis of the helical member, wherein the helical axis is parallel to the linear axis, wherein the actuator and the helical member are configured to cooperate with one another such that (a) motion of the actuator along the linear axis in a first linear direction causes corresponding rotation of the helical member about the helical axis in a first rotational direction and (b) motion of the actuator along the linear axis in a second linear direction that is opposite the first linear direction causes corresponding rotation of the helical member about the helical axis in a second rotational direction that is opposite the first rotational direction.

摘要： A modulable sports wheelchair includes a supporting frame, a front wheel, a pair of rear wheels and a sitting cage. The supporting frame is divided into a front half-frame connecting a support for the front wheel with a frame structure carrying the rear wheels. The frame structure has at least two longitudinal sides oriented in the movement direction of the wheelchair and two transverse sides spaced and oriented in the other direction so as to form the cage, which takes the shape of a compartment free from internal structural elements and is adapted to receive an athlete with an optimal position for propelling the wheelchair depending on the level and type of disability of the athlete.

摘要： The invention relates to an auxiliary mobility system for a wheelchair, comprising a frame, at least one wheel-bearing part and at least one steering element or handlebar, said bearing part being connected to the frame such that it can rotate concentrically about its axial axis under the action of the steering element. The system also comprises means for rotating the bearing part concentrically in relation to an axis substantially parallel to the rotation axis of the wheel.

摘要： A conveyance to carry humans, such as a wheelchair, is described having levers on each side of the wheelchair that are manually moved forward and backward to propel the conveyance. The user is able to shift into forward, reverse or neutral, brake, and change mechanical advantage (gear ratio), all this without removing the user's hands from the drive levers.

摘要： 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.

摘要： A conveyance to carry humans, such as a wheelchair, is described having levers on each side of the wheelchair that are manually moved forward and backward to propel the conveyance. The levers are connected to a tooth clutch mechanism that allow the user to shift into forward, reverse or neutral, brake, and change mechanical advantage (gear ratio), all this without removing the user's hands from the drive levers.

摘要： 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.
