  • Publication number: 20080117632
    Abstract: The invention relates to an ornamental light, and more particularly, relates to a plate-shaped ornamental light which includes a base plate and a plurality of bulbs mounted thereon. A luminous composite layer including luminous material is formed on the base plate. The luminous composite layer constitutes a pattern. The film stores optical energy when in bright environment and emits light when in dark environment. Thus, the plate-shaped ornamental light can provide decorative effect in dark environment regardless of the lighting of the bulbs, hence, meeting requirement of some particular environment such as Christmas night, Disco club or ghost room for adult games.

  • Publication number: 20080073302
    Abstract: An article support rack with accessorial article support racks directly assembled therewith includes a main article support rack, at least one conical lantern ring and at least one accessorial article support rack with split rings. Several flutes are defined in the support legs of the main article support rack. The conical lantern ring consists of two taper-collets and at least one protuberant rib is formed on an inner wall of the taper-collets so that the flutes engage with the ribs when two taper-collets are assembled to be a conical lantern ring around the support leg of the main article support rack, thereby achieving the function of stopping slip up and down. Since the accessorial article support rack can be assembled directly to the main article support rack without disassembling the main article support rack in advance, the extension function of the article support rack is greatly improved.

  • Publication number: 20080073303
    Abstract: A telescopic article support rack includes a primary article support rack, a secondary article support rack, and a clamp. A slide guiding device is disposed between the primary and the secondary article support racks for guiding the primary and the secondary article support racks slide relative with each other. One end of the clamp buckles on the primary article support rack, and the other end buckles on the secondary article support rack when the secondary article support rack is pulled or pushed to a needed position so as to make the primary and the secondary article support racks fixed relatively. The clamp is a double-faced clamp that can fix something in two opposite directions. Since the secondary article support rack can be extended or telescoped freely, the article support rack not only can meet the user's requirement of placing more objects, but also can avoid wasting room space when there is no need for placing more objects.

  • Publication number: 20070251907
    Abstract: A foldable article support rack has a shelf-board and a plurality of bearing legs joined to the shelf-board at spaced locations to support the shelf-board steadily. The shelf-board includes two daughter boards that are connected in a manner to be foldable along a line. The foldable article support rack further includes telescopic link mechanisms connected to the daughter boards and the bearing legs. The telescopic link mechanisms are operable to selectively fold the daughter boards and the bearing legs into a plane for storage or stretch the daughter boards and the bearing legs for use. Therefore, manufacturers or merchants could assembly all components of the rack into finished product and fold it into a package for easy storage and transport and, in turn, consumers purchased the rack may immediately stretch it for use without troublesome assembling operation, while not in use, the consumers can fold it for sparing space.
