The steering device comprises a first portion fixedly connected to the pallet jack between a main wheel and the extensible roller thereof. A second portion pivotally attaches to the first portion. A spring disposed within the first portion urges the second portion to remain in a selected position. A wheel disposes within the second portion. Positioning the pallet jack towards the lowered position, the wheel engages the ground causing the extensible roller to disengage the ground whereupon the main wheel and the wheel define a second turning radius which is lesser than the first turning radius. Upon the wheel contacting a lower cross member of a pallet, the second portion is urged against the biasing force of the spring to pivot relatively upwards and over the lower cross member.

  • Patent number: 7987800
    Abstract: A folding table includes two tabletop halves pivotally joined together at an axle, with one or more legs connected to each half. A transport member, such as a wheel is mounted on the axle. To transform the table from an “in-use” condition to a “transport” condition, the legs are collapsed to seat adjacent to the underside of the associated tabletop half. The tabletop halves are then pivoted toward each other until the undersides are in facing relationship to each other. So pivoting the tabletop halves exposes the transport member, which can be positioned against the ground to roll or slide the table to a different location.

  • Patent number: 7967325
    Abstract: A hand-propelled or vehicle-towed convertible deer cart incorporates side walls that are locked vertically when collapsed to a first geometry of very small size for storage and transport, and also when readily reconfigured for use as a larger transport cart or trailer. When further reconfigured for use as a hunting stand, the side walls are pivoted from vertical to horizontal and form a part of a larger platform in combination with the cart bed. A pair of ladders may be stored within the cart bed when configured as a transport cart. The ladders are pivoted about their longitudinal axis to convert to the larger transport cart, and then extended to full-length ladders in the hunting stand geometry.

  • Patent number: 7963531
    Abstract: The present invention is directed toward a collapsible cart adapted for use in recreational areas. The cart includes a body, a support platform, and a first wheel assembly and a second wheel assembly. Each wheel assembly includes a frame and a wheel adapted to slide along the frame. The frame includes a pivot point that reorients wheels from a stowed position to a deployed position. The cart may further include removable fences, as well as a foldable backstop. In use, the cart may be folded from a deployed position, in which it rolls along a surface to transport items, to a stowed position, in which it is collapsed in a compact geometry for storage. The cart may further be integrated into a chair such that the platform provides a seat and a seat back.

    Abstract: A container assembly is provided that includes a base container that has an upper opening and an upper container mounted in covering relation over the upper opening of the base container. A linkage connects the upper container to the base container in a manner that allows the upper container to be displaced from the covering relation over the upper opening of the base container, so as to permit access into the base container through the upper opening. A support assembly is spaced from the base container when the upper container is displaced from the covering relation over the upper opening of the base container and wheels are disposed toward a lower portion of the container assembly. A handle is provided for rollingly transporting the container assembly on the wheels in a tilted configuration.

  • Patent number: 7918467
    Abstract: A foldable stroller includes a rear composite supporting member interposed between and pivoted to two rear supporting rod parts of a frame; the rear composite supporting member can be expanded to hold the stroller in an in-use position, and it can be compressed so as to reduce the width of the stroller when the stroller is not-in-use; the stroller further includes a composite fixing member, which will fix the rear composite supporting member automatically when the rear composite supporting member is moved to the expanded position; the stroller frame has two front supporting rod parts, which each include an upper rod, and a lower rod pivoted to the upper rod; the stroller can be reduced in its height by making the lower rods of the front supporting rod parts become close to the upper rods.

  • Publication number: 20110018226
    Abstract: A pivot mechanism includes a base member configured to be coupled to a first element and a generally cylindrical rotating member configured to be coupled to a second element. An elongate pin extends through the base member and rotating member and defines a pivot axis. The rotating member is capable of rotating relative to the base member about the pivot axis. The elongate pin is movable in a direction generally parallel to the pivot axis between a secured position and a release position. In the secured position, the rotating member is prevented from rotating relative to the base member, and in the release position, the rotating member is permitted to rotate relative to the base member. The pivot mechanism may be incorporated into a scooter or a tricycle to provide different configurations thereof.
