  • Publication number: 20070057012
    Abstract: A stapler movable between a rest position and a stapling position and having a front end and a rear end. The stapler includes a base, a staple magazine coupled to the base and configured to hold staples, and a driver blade operable to drive staples out of the staple magazine during stapling operations. The stapler further includes an elastic member coupled to the driver blade and operable to move the driver blade during stapling operations. The elastic member utilizes potential energy to move the driver blade during stapling operations. The driver blade is positioned above the staple magazine when the stapler is in the rest position and the magazine is extendable from the front end of the stapler to allow a user to load staples in the magazine. The stapler is configured such that only the potential energy of the elastic member can operate the driver blade during stapling operations.

  • Patent number: 7163044
    Abstract: A roller shade assembly includes a drape bar extending adjacent a rotatably supported roller tube to suspend a portion of a flexible shade fabric windingly received by the roller tube. The drape bar includes a fabric-receiving portion that is shaped along at least a portion of its length to be non-linear so that the suspended portion of the shade fabric defines a curve across its width. The fabric-receiving portion of the drape bar may be continuously curved. Alternatively, the fabric-receiving portion may include substantially straight segments each longitudinally misaligned with adjacently located segments.

  • Publication number: 20060278786
    Abstract: A roller shade mounting system provides a tube-in-tube arrangement for reducing sagging of a roller tube windingly supporting a shade fabric. The mounting system includes a mounting tube received within a roller tube, and first and second annular drive rings located on an outer surface of the mounting tube. The drive rings are secured to the mounting tube and the roller tube secured to the drive rings such that rotation of the mounting tube results in rotation of the roller tube. Each drive ring is located at a distance from an end of the roller tube for limiting sagging deflection of the roller tube. The tube-in-tube arrangement provided by the mounting system provides controlled deflection for the roller tube without necessitating undesirably large increase in the diameter of the roller tube, which could create an undesirable appearance in many roller shade installations.

  • Publication number: 20060195975
    Abstract: The apparatus of the present invention relates to exhausting noxious odors from the vicinity of a toilet. The invention comprises a means of taking in air from the vicinity of the toilet, a filter, and a means of inducing the air flow. The air is taken in by said means of taking in air, passed on to and through the filter, and then passed on to the means of inducing air flow. The air is then discharged from the system. The filter is separate and unitary and can be easily installed and removed without exposure of the filtering matrix within the filter. The contaminants entering the filter, i.e. bacteria and viruses, are killed and odorous gases are trapped in the filter. The person changing the filter is therefore not exposed to the possibility and vulgarity of contact with contaminants entrapped within a used filter when the change of the filter is needed.

  • Publication number: 20060144895
    Abstract: A stapler configured such that the stapler can be used both as a desktop-type stapler and as a hand-held stapler. The stapler includes a base, a staple magazine pivotably coupled to the base, a cover assembly coupled to the base, and a staple driver coupled to the cover assembly. The base includes a front end, a rear end, a top surface, and a bottom surface. The bottom surface includes a first flat portion near the front end of the base, a second flat portion near the rear end of the base, and a recess positioned between the first and second flat portions such that the flat portions and the recess together extend along the entirety of the base length. The recess includes a curved portion that extends across the width of the stapler base and is raised upwardly from a plane defined by the flat portions along the entire length between the first and second flat portions.

  • Patent number: 6845806
    Abstract: A weighting assembly for a roller shade fabric includes an elongated hem bar having opposite open ends and defining an internal cavity communicating with the open ends. A spline secured to an end of the fabric is slidingly received in a pocket defined within the cavity through one of the ends. The pocket includes an opening communicating with the rest of the cavity for passage of the fabric to an exterior through an elongated slot in the hem bar. After the fabric is wrapped on an exterior surface of the hem bar, a portion of the fabric is fed into the cavity through the slot to form a loop for slidingly receiving an elongated rod through one of the ends. The rod has a diameter that is greater than a width of the slot to prevent removal of the rod through the slot.
