Abstract: A skateboard truck (10) for a skateboard (100) having a pivotal member (12) which is arranged to be connected to the deck (102) of the skateboard. The pivotal member (12) carries the wheel assembly (13) of the truck (10). A locking mechanism (14) is also provided. In a first (unlocked) mode of operation, the pivotal member (12) is a able to pivot so that the truck (10) is movable in a to and fro manner. This first mode of operation permits a rider to perform advanced maneuvers using a skateboard (100). In a second (locked) mode of operation, the truck (10) is locked against such to and fro movement by the locking mechanism (14).

Abstract: A skate having a height adjustment mechanism which allows the skater to shift his or her center of gravity by varying the skate's angle of inclination relative to the skating surface, the height adjustment mechanism having a screw for moving a wedge with an inclined surface along a surface of the skate's support assembly, in order to raise or lower the skate's heel.

Abstract: A stroller comprising a respective folding device connected between one of a pair of front legs and a corresponding one of a pair of rear legs. A fastener is provided for pivotally coupling a substantially U-shaped handle to the folding device. A latch assembly is slidably mounted on a respective arm of the handle. The latch assembly is spring-biased to be releasably immobilized with respect to the folding device. The latch assembly is manipulatable to permit the handle and the latch assembly in together to pivot between a forward position and a rearward position.

Abstract: A retractable step apparatus for providing access to a recreational vehicle (6), or trailer includes a mounting frame (10), a top tread assembly (12) pivotally attached to the mounting frame, a center tread assembly (14) swingably coupled to the top tread assembly, and a bottom tread assembly (16) pivotally attached to the center tread assembly. The mounting frame includes right and left mounting brackets (18) and at least one crossmember (20, 22). The top tread assembly includes right and left top brackets (26) and a top step (28) attached between the right and left top brackets. The center tread assembly includes right and left center brackets (36) and a center step (38) attached between the right and left center brackets. The bottom tread assembly includes right and left bottom brackets (46) and a bottom step (48) attached between the right and left bottom brackets.

Abstract: An apparatus which isolates the radiator from the shock and deflection caused by movement of the truck chassis frame during operation of the truck. The apparatus includes a tubular support member connected at a location approximately equidistant from each chassis frame rail to a support member joining chassis frame rails of a truck. The tubular support member is attached to the hood and can also be attached to the front bumper and fenders. Installation of the tubular support member allows designers to contour the hood to the radiator, improving driver visibility and aerodynamics of the truck while not decreasing the fatigue life of the radiator. Securing the bumper to the support apparatus also allows closer fit between the bumper and the hood due to integration of relative movement of these parts.

Abstract: A cup holder mounted to a transversely extending handle of a shopping cart includes a holding member and an adjusting member. The holding member is mounted fixedly to the handle so as to project from the handle. The adjusting member is mounted to the handle so as to be pivotable between an operative position and an inoperative position. The adjusting member has a distal edge facing toward a concave edge of the holding member in the operative position of the adjusting member and away from the concave edge thereof in the inoperative position of the adjusting member. A cup having a frusto-conical wall can be supported between the concave edge of the holding member and the distal edge of the adjusting member with the adjusting member in the operative position or between the concave edge of the holding member and a near portion of the handle with the adjusting member in the inoperative position.

Abstract: A fender for a rotating tire. The fender has a leading section with parabolic shape vanes which control and discharge downwardly spray cast from the tire. A side shield is spaced apart from the upper half of the tire. The shield has specially dimensional louvers which ensure that the flow rate of the air therethrough is uniform as discharged from the shield to cool the tire and brake assembly.

Abstract: A knockdown golf cart with reduced volume composed of a tube frame assembly, an upper and a lower bracket assemblies, a handle assembly, a wheel support assembly, an L-shaped beam member and a bracket board. The tube frame assembly includes two circular tubes which are formed with inner slide grooves and connected to each other by a fixing ring member. A folding link is connected to a folding link seat disposed under the fixing ring member. The upper and lower brackets are disposed at an upper and a lower ends of the tube frame assembly. The handle assembly includes a slide block slidably fitted in the slide grooves of the circular tubes. The wheel support assembly is secured to the fixing ring member of the tube frame assembly and pivotally connected with the folding links thereof. The L-shaped beam member has a rectangular end fitted with the lower bracket and a flat end fitted with the bracket board.

Abstract: A flywheel with electric batteries mounted thereon is provided for an electrical vehicle. The flywheel incorporates the weight of the batteries to store kinetic energy. The flywheel is suspended by magnetic force and is rotated about a central flywheel shaft. The flywheel shaft is fitted with an electric drive motor, a hydraulic pump and a generator. The electric vehicle utilizes the energy stored in the spinning flywheel to supply peak electrical demand during the acceleration of the vehicle. When the vehicle stops the flywheel energy recharges the electrical batteries. The flywheel is driven by the electric drive motor. The hydraulic pump is used to drive a hydraulic motor which in turn drives the vehicle wheels. When the hydraulic motor brakes the wheels, kinetic energy is stored into the flywheel. The generator supplies supplemental vehicle power.
