LOW COST HINGE FOR A PAPER TRAY (Cont'd)

A paper tray assembly 10 has a stop 12 at the end of the tray 14 that can be pivoted down on top of the sheet supporting surface 16 of the tray when not in use. A low cost hinge connects the stop 12 to the tray 14 as shown in Figures 1 through 3, and includes two sheet metal parts and one extension spring 15 that are integral parts of the stop and the tray.

For simplicity, only one hinge and a small portion of the tray is shown. The tray 14 has a tab with a 90 degree "V" bend that functions as a pivot for the end of the stop 12. The tabs 18, which are part of the stop, prevent excess lateral movement of the stop, and also prevent the hinge from being pulled apart from an excessive overriding force. The spring 15 holds the hinge together and provides the necessary force for the over-center detent.
