Abstract
A roller-equipped platform movably supported upon a tabletop having a straight, accessible rear edge, the platform including a straight depending flange received in a guide channel defined by the rear edge of the tabletop and a guide track secured to that rear edge. Stop elements at opposite ends of the track limit the extent of sideways movement of the platform upon the tabletop.
Claims13
A platform assembly for tabletop use, comprising a platform having an enlarged planar top wall and front, side, and rear flanges depending from the periphery of said top wall and together defining a shallow, downwardly-facing cavity;
- a plurality of axially-elongated cylindrical rollers mounted within said cavity adjacent said front and rear flanges with their rotational axes disposed in spaced parallel relation and their lower portions projecting beneath said side and front flanges;
- said rear flange extending along a vertical plane normal to the axes of said rollers and including an extension projecting substantially below said rollers;
- and track means substantially longer than the width of said platform and adapted to be affixed to a vertical rear surface of a tabletop;
- said track means defining an elongated upwardly-facing guide channel for receiving said rear flange extension and for guiding movement of said platform therealong.
In combination, a table having a tabletop with a horizontal work surface and a straight, vertical rear surface;
- a platform supported on said work surface;
- said platform having a top wall and having front, side, and rear flanges depending from the periphery of said top wall and together defining a shallow, downwardly-facing cavity;
- a plurality of rollers mounted within said cavity adjacent said front and rear flanges with their rotation axes disposed in spaced parallel relation and their lower portions projecting beneath said side and front flanges and supported on said work surface;
- said rear flange extending along a vertical plane normal to the axes of said rollers and including an extension projecting substantially below said rollers along said rear surface of said tabletop;
- and track means secured to said tabletop along the rear surface thereof, and below said work surface, for defining an elongated upwardly-facing guide channel slidably receiving said rear flange extension for guiding movement of said platform across said work surface and adjacent said rear surface.
