  • Patent number: 6991431
    Abstract: The present invention relates to a ceiling fan blade capable of producing full wind pressure and much wind. The solution of the present invention is to form a front and a rear wind receiving surfaces on the ceiling fan blade. A tangent angle of the rear wind-receiving surface is bigger than that of the front wind-receiving surface. A wavy wind guide surface is formed between the two wind receiving surfaces. The wavy wind guide surface and the two wind receiving surfaces can effectively increase the wind pressure and the wind; in addition, sinuous flow is substantially reduced when the blade is rotating.

  • Patent number: 5921648
    Abstract: A drawer combination of a storage bin which is convenient and firm in assembling and the life of use thereof is increased, it is comprised of an injection moulded plastic container and a front panel. The front side of the container is opened and is provided with a plurality of engaging pieces, a gripping edge, a grip, a plurality of engaging holes, two connecting edges and two engaging grooves. The-front panel is provided with a plurality of engaging holes, recess chamber, an opening, an engaging edge, a plurality of locking hooks, two abutting edges and two engaging hooks, in order to be connected to the front side of the containers. A user can extend his hand into the groove to hold the grip through the opening, so the force exerted on the grip can be distributed through the engaging structure to the whole front edge of the container, thereby preventing damage to the grip.
