Roller tray for facilitating the movement of heavy objects

摘要

In a roller tray (3) with rollers (4) rotatably supported above a base (8), the main novel feature is that the rollers (4) are supported on stationary shafts (5) resting in recesses (5) on upstanding webs (7) and held in position by engagement with channels (9) in end pieces (10), temporary elastic bending of the base (8) and/or the shafts (5) being necessary to assemble the complete tray (3). With this arrangement, no screws or other fasteners are needed. The tray (3) may be used on its own as a trolley (turned upside-down) to support heavy objects to be moved, or else in a great number of trays secured to a roller mat (not shown), that may be flexible. <IMAGE>
