  • Patent number: 5601270
    Abstract: A paper holder includes a generally rectangular holder plate, a clip member mounted on the holder plate and adapted to clamp a sheet of paper which lies on a front side surface of the holder plate, and a support plate. The holder plate has a rear side surface opposite to the front side surface and a horizontal row of interconnected abutting blocks which are fixed on the rear side surface thereof and which are different in thickness so as to define a stepped surface thereon. The support plate is attached pivotally and inclinedly to the holder plate and has a horizontally movable sliding unit thereon to contact the stepped surface in such a manner that the sliding unit abuts against a selected one of the blocks of the holder plate so as to form a predetermined angle between the holder plate and the support plate.

  • Patent number: 5516072
    Abstract: A small sized article mounting device for mounting an article or ornament such as a picture plate, a record jacket, a photograph, a book, a mirror, a painting, a ceramic plate and the like is constituted by a supporting member and a standing member each having a predetermined thickness. The supporting member has one end and the another end, and a plurality of grooves near to the other end. The standing member also has two ends. The length of the grooves is larger than the width of one end of the standing member and shorter than the width of the other end of the standing member. The width of each groove is nearly equal to the thickness of the standing member. The two members are assembled together by utilizing either one of the grooves, whereby the standing member is adapted to support the rear surface of the article, and the supporting member to support the lower portion of the article. The device is supported by one end of the supporting member and the other end of the standing member.

  • Patent number: 5501423
    Abstract: A portable easel with tray and table composed of two legs, joined at the top by a crosspiece having in it pegs for hanging a thin, rigid easel board to serve as backing for commercially available easel pads. The legs pass through holes at their approximate midpoint in a tray table which senses as a tray for marking instruments in the front, a table for papers, books and the like in the rear, and which holds the legs in their splayed position. The tray table rests on fittings which support the upper structures, join the legs laterally for rigidity at their midpoint, and into which the lower portion of the legs may be fitted and removed. The lower ends of the legs have rubber tips to increase friction with the floor, or may be attached to a rectangular base to afford greater stability. The lower halves of the legs, when removed, enable the easel to function as a table model, and reduce the size of the structure for transport and storage.

  • Patent number: 5485980
    Abstract: An inverted book stand having a book support platform comprised of two pivotally connected, transparent panels. The panels can be moved from a first, stowed position, where the panels are folded together and in close proximity to each other, to a second, in use position, where the panels are folded open to an angle of less than 180.degree. to form the support platform. The panels are formed with an integral, angle limiting feature at the pivotal connection to maintain the angle between panels when they are in the open position. Support members are pivotally connected to the outer edge of each panel, opposite to edge of the panel from where the panels are connected to each other. The support members can be moved from a first, stowed position, wherein each support member is in a closed position parallel and adjacent to its respective panel, and a second, in use position, where the support member is pivoted to an angle of more than 90.degree. from the panel surface.

  • Patent number: 5480119
    Abstract: A lightweight portable podium is provided for use in lectures and other speaking events. The podium rests on a table or desk and has an inclined shelf which forms the upper surface on which notes and papers can readily repose. The shelf is screened from public view and protected from wind by a main panel that forms the front of the podium and two side panels. The four pieces that comprise the podium are substantially flat and can be readily disassembled into a flat unit for storage or transit. The upper edge of the shelf is captured by two channels formed between the main and side panels. For disassembly the shelf is first pivoted to be parallel to the main panel. It is then slidden in the channels in a downward direction into contact with the main panel. The two side panels are then folded in over the shelf/main panel combination to form a flat, thin unit for storage or transit.
