A rapid and simple LED display light box includes a base, a support rod and a top supporting element. One end of the support rod can be fixed to the base while the other end thereof is connected to the top supporting element. An LED light bar can be arranged on the base and/or the top supporting element. The LED light bar can be lightened by a storage battery system under the places without power facilities. The light source with the LED light bar supports multiple mounting modes and can meet requirements of various brightness. The structure is firm, assembly is rapid, and collection is simple.

A background wall structure. The background wall structure includes an object placing plate and a fifth straight rod, where a four-way member is movably mounted at each of the two sides of the fifth straight rod; a first straight rod is movably mounted at the top of each four-way member; the object placing plate is fixedly mounted between the first straight rods; an object placing plate fixing block is fixedly mounted at one side of each first straight rod; a second straight rod is movably mounted at the top of each first straight rod. The bottom of the background wall structure adopts the four-way members, the first elbow pipe and the fifth straight rod which are connected to form a triangular base, so that the background wall structure is stable after assembling, and is convenient to disassemble.

A handheld placard includes a body made of a rigid paper material. The body includes a front surface, a rear surface, a bottom edge, side edges, a top edge, and an inner edge defining a handle opening through the body. A handle flap extends downward from the bottom edge of the body and is connected to the bottom edge at a first fold line. The handle flap includes an upper portion joined to a lower portion by a second fold line.

A portable, aluminum advertising platform system for store front and street side promotions. This rugged, lightweight platform has multiple vertical mounts and substantially stretches both horizontally and vertically providing numerous configurations. Supported signs and products are attached only at the top which allows them to freely swing; wind resistant. The structure is made from 2 aluminum tubes that slide inside each other; telescopes. Fastening occurs using thumb screws attached to the outer tubes that when twisted, pinches the inside interconnecting tubes. Tubes come in 1 to 4 foot lengths and can couple together to form much larger members. The 2 side frames are tubes welded together. The 4 leg levelers telescope 3 feet both horizontally and vertically to level the cart on rough uneven terrain. Levelers also act as durable brakes when any wheels are lifted off the ground. Detachable large 8 inch wheels swivel for easy maneuvering.

A wheel/foot assembly for a sign display stand or other object includes a cradle partially enclosing an optional wheel. The assembly is releasably attachable to a leg for a sign display stand, protects the leg and can be easily replaced if worn. The assembly protects wear on the stand and permits the sign display stand to be wheeled, rather than dragged or carried. Because the assembly is releasably attached, it can be replaced easily if damaged or worn.
