  • Patent number: 5620162
    Abstract: An adjustable paper holder including an elongate support member adapted to be attached along either side of a computer monitor with the support member extending generally parallel to its front surface; and a sheet support plate that is mounted on the support member for pivotal movement around both a normally horizontal pivot axis that is generally normal to the length of said support member and parallel to the front surface of the computer monitor and a second pivot axis parallel to the edges of the sheet support plate and adjacent one of its edges, and also mounted for movement of its normally horizontal pivot axis longitudinally of the support member. A paper clamp assembly is mounted on the sheet support plate with a surface on the clamp plate against which paper is clamped generally co-planar with the front surface of the sheet support plate, and is moveable to accommodate different length papers to be held on the sheet support plate.

  • Patent number: 5584535
    Abstract: A footrest to be supported on a floor for which the height of the footrest from the floor and the angle of a foot support surface on the footrest with respect to the floor are independently adjustable. Projections on one portion of the footrest are movable in slots in another between spaced retaining portions in which the projections are frictionally retained to change the height of the footrest; and a platform defining the foot support surface is pivotable against the restraint of a friction clutch to change its angle with respect to the floor.

  • Patent number: 5547154
    Abstract: A wrist rest assembly for use along the front edge of a device to be operated by a person's hands or fingers, such as in front of a computer keyboard, including an elongate base assembly on which is supported an elongate pad. The base assembly has a top portion supporting the pad, a bottom portion adapted to be supported on a horizontal surface and structure that allows the top portion to be supported on the bottom portion with the top surface of the pad at two different distances above that horizontal surface by switching ends of the top portion with respect to the ends of the bottom portion.

  • Patent number: 5165570
    Abstract: A dispenser for paper sheets from a stack comprising a plurality of the sheets disposed one on top of another, each sheet having a band of pressure sensitive adhesive coated on one surface adjacent one edge thereof and being free of adhesive coating along a portion adjacent an opposite edge thereof, and the sheets being stacked with the adhesive coating on each successive sheet disposed along alternate opposite sides of the stack and releasably adhering the sheets together to maintain the sheets in the stack. The dispenser has surfaces defining a cavity adapted to receive the stack including opposed end surfaces adapted to be engaged by the opposite sides of the stack, and two spaced friction surface portions extending generally toward each other from the upper ends of the end surfaces which are generally arcuate and concave about an axis parallel to the upper ends of the end surfaces.
