Abstract: A walker having a frame which provides two front legs. Two rear legs are attached to the frame. A cross member provides support for the device which is supplemented by a link. Each of these structural members is in a pivotal relationship with the remaining members so the walker may be folded for storage. The cross member and link provide bracing for structural integrity, but are also incorporated into the folding structure. The optional seat is also in a pivotal relationship with the device. The seat prevents the walker from being folded while it is being used as a walker.

Abstract: The present invention discloses a foldable structure of a scooter, which can be operated with one hand, and the scooter comprises a bottom module having a front wheel, wherein a handle control rod of the coupling frame being extended from the rear end of the bottom module, and a tail module having a rear wheel with a footrest. By passing the axle through such members, the handle control rod and the footrest are latched to form a coupling base, and the foldable structure of the scooter characterized in that the coupling base has two positioning holes on one of its sides, and an arc sliding groove on the other side, and a fixing structure latched with the coupling base inside the coupling frame, and such fixing structure is the link rod passed through by a spring inside the coupling frame.

Abstract: An improvement to a standard three wheeled walker to render it usable for carrying objects on a folding tray mounted between the vertical supports of the walker. A panel is split into two portions, which are pivotally joined together with a piano hinge. A “U” clamp having a mounting bracket and hinge is mounted on each vertical support. The hinges are attached to the bottom edges of the two split panels to attach the folding tray across the space between the two vertical supports. The tray folds upwardly when the walker is folded.

Abstract: A scooter rear wheel brake comprises a rear wheel cover which is mounted on the scooter footboard such that the rear wheel cover is located over the rear wheel of the scooter. The rear wheel cover is provided with a brake applying block and a brake shoe mount corresponding in location to the brake applying block. The brake shoe is linked with the brake applying block by which the brake shoe is actuated to act on the rear wheel in motion.

Abstract: A scooter having a streamlined design and a proportioned frame suitable for high-speed operation by tall and heavy riders, such as adults. The scooter includes a frame having a down tube which forms an angle of approximately 110 degrees with a horizontal rider deck and having a head tube mounted at an approximate angle of 40 degrees to the down tube allows for the front steerable wheel to be safely operated in turns at higher speeds of travel by maintaining a near-vertical position of the front wheel with respect to the ground.

Abstract: A folding front support for a skateboard, in which the front support has a longitudinal groove at two sides near the bottom end including an expansion ring at the top and middle positions. Two pivoting ears each with a throughhole are fitted on the connection part between the frame and the front support. A turning pin with an oval member is inserted into the throughholes of the pivoting ears, and a fixing effect will then be created by means of a fixing ring. A deep groove is disposed between the pivoting ears so that the front support whose outer diameter is smaller than the inner diameter of the deep groove can be plugged into the deep groove in a telescopic state for adjusting the upright height of the front support. Furthermore, the front support can be folded in direction toward the rear side of the frame.

Abstract: A children's wagon comprising a wagon body, a bottom wall, and front and rear bolsters secured to the bottom wall. The front bolster is pivotally secured to the bottom wall and a pin is associated with the bottom wall and is adapted to extend downwardly therefrom to interfere with the front bolster movement to thereby minimize the possibility of tipping of the wagon. The pin is adapted to be moved upwardly out of interfering position whereby the front bolster can be moved 180° in either direction to thereby place the wagon in more convenient positions for transportation and storage. The front and rear bolsters are each provided with shock absorbers positioned above the front and rear axles adjacent each of the wagon wheels. Slotted vertically extending extensions on each side of each bolster receive the wagon axles and provide for vertical movement of the bolsters relative to the axles.
