Abstract: A detachable wheelchair for the disabled people is provided. The wheelchair is composed of a seat, a right wheel frame, and a left wheel frame. The seat is composed of a seat frame and a seat cushion. Two hollow shafts and one fixing nut are installed on the left-hand and right-hand side of the seat frame respectively. Two positioning shafts and one fixing bolt are arranged on the right and left wheel frame respectively. The positioning shafts on the wheel frames can be inserted into the hollow shafts on the seat frame, and the bolts can be screwed into the nuts. After the left and right wheel frames are fixed firmly onto the seat frame, they are assembled into a wheelchair.

Abstract: The invention discloses a vehicle seat adjusting apparatus including a seat base, a mechanically operated first transmission device, a first supporting plate, a mechanically operated second transmission device, and a second supporting plate. When the first transmission device is operated to be stationary, the second transmission device is capable of being operated to rotate a rotation shaft thereof to rotate the second supporting plate with respect to the first supporting plate. The second transmission device also actuates a first gear thereof to meshably rotate on a stationary first rack member of the first transmission device, such that the second supporting plate, together with the first supporting plate, moves with respect to the seat base along a direction defined by the first rack member.

Abstract: A rotating car seat mechanism includes a seat base, a sliding plate, a rotating plate, a guiding socket plate, an axle defining an axis of rotation and a cylindrical pivot rod. The sliding plate is placed inside a car, allowing an upper end of the cylindrical pivot rod to be positioned at the exit of the guiding socket, further enabling the rotation out of the car door and sliding the cylindrical pivot rod into the guiding socket. Due to the path defined by the guiding socket customizing the movement of the cylindrical pivot rod, the rotating plate not only rotates on the axle, but also drives the axle forward. After applying a suitable degree of motion, the rotating plate exceeds out of a narrow space of the car, whereas an opposite amount of motion enables the rotating plate to return to the original point.

Abstract: A non-sectional locking buffer device. The device utilizes a screw ascending and descending principle as a buffering function, wherein ball bearings or outer screw grooves are configured on a central shaft of the buffer device to operate in coordination with inner screw grooves or ball bearings configured on an inner wall of a buffer chamber. The inner and outer screw mechanisms rely on slippage of the ball bearings in the screw grooves, to reduce a jolting force from repositioning or returning of an upright support, thereby reducing buffer malfunction.

Abstract: A rotating car seat mechanism includes a base seat, a sliding plate, a rotating plate, a guiding socket plate, a rotating axis and a cylindrical pivot rod. The sliding plate is placed inside a car, allowing an upper end of the cylindrical pivot rod to be positioned at the exit of the guiding socket, further enabling the rotation out of the car door and sliding the cylindrical pivot rod into the guiding socket. Due to the designated dotted centric line as illustrated by the guiding socket customizing the movement of the cylindrical pivot rod, the rotating plate not only rotates on the rotating axis, but also drives the rotating axis forward. After applying a suitable degree of motion, the rotating plate exceeds out of a narrow space of he car, whereas, an opposite amount of motion enables the rotating plate to return to the original point.

Abstract: Universal car seat-adjusting slide rail structure including a slide bar and a slide frame. The slide bar is supported by multiple ball members and plastic circular rods and stably slidably fitted in a slide channel of the slide frame. The surface of the slide bar is formed with multiple locating holes and two connecting lugs are respectively detachably locked at two ends of the slide bar by screws. Therefore, a user can selectively directly lock the slide bar on the bottom face or front and rear sides of the car seat in accordance with the type thereof. Alternatively, the slide bar can be locked on left and right sides of the car seat via an L-shaped auxiliary board so that the slide bar can be widely applied to various kinds of car seats. Moreover, a resilient member is disposed between a fixing section of the slide frame and the clutch control bar.
