Adjustable tray riser
First Claim
1. An adjustable stacking letter tray system, comprising:
- upper and lower letter trays, said trays having longitudinally extending sidewalls and said upper letter tray having at least one profiled protrusion projecting downwardly from a bottom surface;
at least one riser body having lower attachment means for securing to a longitudinally extending sidewall of said lower letter tray, and upper attachment means for receiving said upper tray protrusion, whereby attaching to said upper letter tray and placing said upper and lower trays in a spaced apart orientation, andsaid upper attachment means having adjustment means for selectively placing said upper letter tray in alternate longitudinal alignments relative to said lower letter tray with said riser lower attachment means remaining in a fixed location along said lower tray sidewall.

Abstract
An adjustable support riser for vertically stacking letter trays is disclosed, comprising a riser body (10) having a lower clothespin type attachment configuration (30, 32, 42) for securing to a lower letter tray, and an upper attachment socket (12) for attaching to a downwardly projecting (52) foot projection of an upper letter tray, whereby the upper and lower letter trays are in a spaced apart orientation. The upper attachment socket is provided with an elongate ovular shape of enlarged dimension, whereby the upper tray can selectively placed in either a forward or a rearward socket location relative to the upper end of the riser. The orientation of the upper letter tray relative to the lower letter tray can thereby be selectively altered from a parallel and co-aligned configuration to a staggered or stepped configuration. The lower attachment means of each riser is provided with offset cantilevered fingers (30, 32, 42), which distribute stress along the line of attachment to the lower letter tray. A reinforcement flange (40) is provided to extend along each cantilevered inward finger, whereby adding rigidity and strength to the lower attachment point.

15. An adjustable stacking letter tray system, comprising:
-
upper and lower letter trays, each having longitudinally extending sidewalls and said upper tray having at least one profiled protrusion extending downwardly from a bottom surface thereof; a riser body having lower attachment means for securing to a lower letter tray, and upper attachment means for attaching to an upper letter tray, whereby said upper and lower trays being in a spaced apart orientation, and said lower attachment means comprising dependent inward and outward cantilevered finger means, said inward and outward finger means having opposed parallel surfaces, said parallel surfaces being longitudinally offset and spaced apart to receive therebetween an upper edge of a sidewall of said lower letter tray, whereupon said riser parallel surfaces extending parallel to said upper edge of said lower tray and being repositionable longitudinally therealong. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)
