  • Patent number: 5367829
    Abstract: A security gate for children having a pair of gate sections that slide relative to each other to vary the effective width of the gate. The sections carry bumpers on their outer vertical side rails, and the bumpers on one side rail are extendable so that they force the bumpers to frictionally engage the sides of an opening to be closed by the gate. Independent of the bumpers brackets are provided on the vertical outer side rails and the sides of the opening to position the gate in the opening and resist the gate from being pushed out of the opening. The gate may be permanently mounted in the opening by hinges or may be removable from the opening.

  • Patent number: 5000601
    Abstract: A lipstick container is disclosed having an inner body member with an upper tubular portion. An outer body member surrounds the tubular portion and is mounted thereon for relative rotation thereabout. A base member surrounding the outer body member is in fixed engagement with the inner body member. A slidable cup received in the tubular portion carries the lipstick mass. Relative rotation between the inner body member and the outer body member moves the slidable cup between a protracted position and a retracted position. A central ring partially surrounding the outer body member and secured to the base member includes a plurality of projecting biased elements for engaging the outer surface of the outer body member to provide a radial force thereon whereby an approximately constant torque is required to enable relative rotation therebetween.
