| 040606020 | With wheel | 6 |
| 20080209783 | SYSTEM AND METHOD FOR MEDIA DISPLAY - 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. | 09-04-2008 |
| 20090320341 | SIGN STAND WITH ROLLING BASE - 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 wall 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. Wheels are provided on one edge of the base member in order to allow the sign stand to be rolled and easily moved to different positions. Axle members secure the wheels to the base member. One or more resilient members can be used to connect the sign display member to the base member. | 12-31-2009 |
| 20110010974 | Multipurpose sign bases for supporting temporary roadway safety signs and the like - 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. | 01-20-2011 |
| 20110197482 | Sign Stand With Rolling Base - 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. | 08-18-2011 |
| 20120066947 | SIGN ASSEMBLY - 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. | 03-22-2012 |
| 20150101223 | WHEEL APPARATUS - 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. | 04-16-2015 |
