Abstract: The disclosure relates to a support stand structure with a quick-release wheel mechanism, which includes a stand, a detachable wheeled seat, and multiple fasteners. The stand includes a base. The base has multiple slots and a rear wall. The detachable wheeled seat includes a board and multiple wheels. The board has a front plate disposed above the base and a rear plate projecting over the rear wall. The front plate has multiple tabs extended downwardly and inserted in each slot. Each tab has a through hole. The wheels are mounted on a bottom of the rear plate. The fasteners are installed on a bottom of the base. Each fastener includes a movable pin. Each movable pin is attachable to and detachable from each through hole. Therefore, the support stand has the advantages of stability and saving space with detachable wheels.

Abstract: A mobile support structure for a display device includes a cross bar having a first end and a second end, a display, a first pair of legs, and a second pair of legs. A first coupling defines a first transverse cavity receiving the cross bar and a first pair of axial cavities receiving the first pair of legs. A second coupling defines a second transverse cavity receiving the cross bar and a second pair of axial cavities receiving the second pair of legs. A locking mechanism is disposed in at least one of the cross bar and the first pair of legs. A wheel coupling includes a wheel and is engaged with at least one of the first coupling and the second coupling such that when in a moving position, the wheel contacts a ground surface and rolls the display from a first location to a second location.

Abstract: A large size display is transportable, being construed of multiple rigid segments containing light emitting diodes (LED's). The rigid segments are linked by hinges or cables so the display is flexible and can be rolled up for storage and transport. The display can be unrolled upward or downwards such as from a protective container, such as a canister or truss. The weight of the display on the linked hinges or the tensioned cables provides sufficient rigidity. Such cables, like a signal and power distribution bus, are connected to the rear of each rigid element. The display can be repaired by removing and replacing selected rigid segments from the front thereof.

Abstract: A bicycle frame for employment in a bicycle for riding by a user in a substantially vertical as-used position. The frame has a shape which defines an aperture within the interior surface of a surrounding frame. The frame is preferably formed of planar material which has ends which do not block the view into the aperture when the bicycle is ridden. Whereby space for indicia on an inserted vertically disposed planar member is maximized. The planar member has a perimeter defining a shape that is complimentary to the shape of the aperture and when engaged therein provides support to the frame to prevent deformation thereof when in the as-used position under a load. The indicia positioned on the planar member may be advertising which can easily be changed using removable planar members with different indicia.

Abstract: A sign assembly includes a panel and a base. The base is configured to be attached to the panel via a resilient member. The bottom surface of the base defines a pair of cavities. The cavities are positioned substantially adjacent to a forward edge of the bottom surface. A pair of wheel assemblies is secured within respective cavities on the bottom surface. Each wheel assembly includes a housing that houses an axle and wheel.

Abstract: A portable sign stand with wheels or rollers, an adjustable weighted base member, and a sign display member. The base member has one or more compartments so that liquid or solid ballast can be added to stabilize the sign stand in windy conditions. The upper and lower surface members of the otherwise hollow base member are joined together at one or more locations where the sign display member is connected to the base member. The base member can be made by blow molding techniques. One or more wheels are provided on the base member in order to allow the sign stand to be rolled and easily moved to different positions. One or more resilient members can be used to connect the sign display member to the base member.

Abstract: The invention provides a media display system and method that allows a user to easily maneuver through crowded areas while providing advertisements that can be selected and altered even while the media display system is in use. According to the invention, the system operates on a regenerative breaking system that recharges the battery as the system is in brake-mode or as a result of the media display in the shape of an airfoil contributing to the regenerative breaking mechanism.

Abstract: A multipurpose sign base suitable for supporting temporary roadway safety signs and the like includes an upstanding mast supportable atop a ground or support surface by a substantially horizontally extending, elongate, support member connected to a lower region of the mast, and by a plurality of elongate leg members of adjustable length each having an upper portion movably connected to a central region of the mast, and each having a lower portion movably connected to a different foot adapted to engage a different area of an underlying ground or support surface at locations arrayed about the mast. An upper region of the mast is connectable to a roadway safety sign or the like, to support and display the sign. The legs and feet have retracted positions near the mast. A rearwardly extending formation of the horizontal support member preferably can be coupled to a vehicle hitch so the sign base also can be supported on a vehicle for transport while displaying a sign carried by the mast of the sign base.

Abstract: A media display system and method is provided. The media display system comprising a two wheeled base configured for a operator to stand on; a steering column operatively connected to said base; a display means for a user standing on said base to hold and steer, said display mean allowing messages to be displayed; a handle operatively connected to said display means; and at least one wheel operatively connected to said media display such that said media display system can move 365 degrees.

Abstract: The apparatus of the present invention is a customized non-rotatable decorative displaying image mechanism wheel assembly. The wheel assembly comprises a wheel mount supportable by of the wheel of a vehicle. A protective cover is affixed to the wheel mount to form a housing with an interior cavity therein. The display holder can be transparent or translucent with any image, logo, emblem, insignia or hologram covering affixed thereto. A display holder and member is positioned behind the protective covering within the cavity of the housing. The display holder is bolted with predefined weighted members and ball bearings such that the display holder and member remain stationary during within the interior cavity as the vehicle's wheel turns. Alternatively, predefined weighted members may not be used for certain design, since shaft members may stabilize image. The display member can be illuminated by a light source which is powered by an electromechanical power source utilizing the Faraday Effect.
