  • Publication number: 20140369740
    Abstract: The coupling device contains at least an orthogonal joint member, a number of connector members, and at least two oblique joint members. The orthogonal joint member has at least 6 faces, 5 of which are configured with a through hole, and a through slot and a blind trough extended from the through hole. Each connector member contains an axial pin, a wing plate on a front tip of the axial pin. Each oblique joint member is L-shaped, and each of the two outer faces of the L-shaped body is configured with a through hole, and a through slot and a blind trough extended from the through hole. A coupling column is configured behind one of the two outer faces. With the coupling device, a number of beams can be joined into a framework to be used as a storage shelf or the skeleton of a game house.

  • Publication number: 20130114370
    Abstract: A magnetically-driven stirring structure includes a transmission base, and a cup can be mounted to the transmission base or positioned on the transmission base. The transmission base includes a rotary mechanism, and the rotary mechanism is coupled to a first magnetic member. The rotary mechanism is coupled to an operating member in such a way that the operating member is exposed outside the transmission base. With a second magnetic member being placed in the cup, in making or brewing a drink in the cup, through actuation caused by the operating member, the rotary mechanism is made rotating and driving the first magnetic member to rotate, whereby the second magnetic member placed in the cup is caused by magnetism to rotate in the same direction so as to achieve stirring of the drink contained in the cup.

  • Publication number: 20120228367
    Abstract: The collapsible storage box contains two rigid lateral plates, two flexible longitudinal plates, a flexible first base plate connecting the longitudinal and lateral plates' bottom rims, and a rigid second base plate stitched or adhered to a top side of the first base plate along a longitudinal middle section of the second base plate. A rigid support plate is connected to the top rim of each longitudinal plate. To put the storage box to use, the lateral and longitudinal plates are raised and the two support plates are flipped downward so that their bottom rims are pressed against the second base plate. When the storage box is not in use, the support plates are flipped outward and, by the flexibility of the two longitudinal plates, the lateral plates are folded inward. The storage box then turns into a flat shape for easy storage and transportation.

  • Publication number: 20120181904
    Abstract: A multifunctional storage box includes a frame-like elementary unit composed of two horizontal boards and two vertical boards and a positioning piece fit to an end of the elementary unit. Each vertical board includes first and board segments that are connected to each other by a movable connection member. The elementary unit has an end forming a positioning structure, whereby the positioning piece is selectively fit to the positioning structure to form a box for receiving and storing various articles, or a number of such boxes can be stacked to form a piece of furniture, such as drawer, closet and desk. No tool is required and the assembling is easy and convenient. When not in use, the positioning piece is removed to allow the first and second board segments to be folded by means of the connection member into a flat configuration for easy carrying and storage.

  • Publication number: 20110240636
    Abstract: The collapsible storage basket contains two rigid longitudinal plates, two flexible lateral plates, a flexible first base plate connecting the lateral and longitudinal plates' bottom rims, and a rigid second base plate stitched or adhered to a top side of the first base plate along a middle section of each of the second base plate's lateral edges. The top rims of the longitudinal and lateral plates wrap the edges of a rectangular frame. To use the storage basket, the frame is pulled upward to raise the longitudinal and lateral plates whose bottom rims are pressed against the second base plate, thereby forming a storage room for various objects. When the storage basket is not in use, by the flexibility of the two lateral plates, the longitudinal plates are folded inward and the storage basket turns into a flat shape for easy storage and transportation.

  • Publication number: 20110220693
    Abstract: An extendable clothes hanger includes a base and two symmetric brace members. The base includes a hanging hook and an outer surface forming successive corrugation to serve as a skidding prevention structure. The base forms therein an elongate channel. Each brace member includes a bar, which has an end extending through a stop plate and is fixed to a curved end claw that is rotatable to be set at different angular position and an opposite end movably received in the channel of the base. The stop plate is then mounted to an end of the base to thereby complete the hanger. The bars of the brace members are extendible out of and/or retractable into the channel of the base to adjust a distance between the base and each end claw so as to realize adjustment of length of the hanger for hanging clothes of various sizes.

  • Publication number: 20110220694
    Abstract: An extendable clothes hanger includes a base and two symmetric brace members. The base includes a hanging hook and has front and rear surfaces that are recessed to form channels extending in an inclined manner from opposite ends of the base toward a central portion and each having an inner face that defines a plurality of spaced positioning holes. Each brace member includes an elongate member that is bent to form two symmetric bars connected at one end that is curved downward slightly and having opposite ends bent inward to form barbs. The brace members are received in the channels with the barbs selectively and detachably received in the positioning holes. The brace members are extendible out of and/or retractable into the channels to adjust a distance between each brace member and the base so as to realize adjustment of length of the hanger for hanging clothes of various sizes.

  • Publication number: 20110220604
    Abstract: A collapsible rack includes symmetric support frames composed of vertical bars and horizontal bars and top and bottom frames connected between the support frames in a movable manner. The top and bottom frames are composed of connected movable left and right boards, which have front and rear faces that define recessed channels. Spaced fitting holes are defined in the channels. Straight bars form pegs. The top and bottom frames are of movability to allow the top and bottom frames to be collapsed to a stacked flat configuration when the rack is not in use, so as to facilitate storage and transportation. When the rack is to be used, the top and bottom frames are expanded and the straight bars are set to have the pegs fit in the fitting holes defined in the left and right boards to fix the top and bottom frames in the expanded position.

  • Patent number: 6575486
    Abstract: A folding structure of a children tricycle is disclosed. The folding structure has a pivotal seat connected to a front and rear wheel rod. The fixing rods of the front and rear wheel allows the pivotal seat to rotate, wherein the rear wheel fixing rod is connected to a substantially “C”-shaped fixing seat and the through hole near to the top edge of the two wheel rods is pivotally connected to the fixing seat. The top of the wheel rod is provided with a resilient fastener such that the wheel rod can make use of the through hole as fulcrum to provide extending and folding. The fastener can engage at different fastening holes so that when in use, the wheel rod can be extended and when not in use, the wheel rod can be folded. Thus, the folding structure allows the tricycle to be retracted for storage and transportation.
