Thermoformed platform
First Claim
1. A pallet for carrying a load comprising:
- a thermoformed pallet shell having a first shell half formed from a first sheet and a second shell half formed from a second sheet; and
a support structure formed from a third sheet disposed between and instantly fused to said first shell half and said second shell half to provide support to said thermoformed pallet shell, said support structure extending across a length of at least one of said first shell half and said second shell half, said support structure having an alternating cross-sectional shape such that said support structure is alternately fused to said first shell half and said second shell half.

Abstract
Articles constructed of a plurality of scuffed sheets have improved sheet-to-sheet bond strength and surfaces with high coefficients of friction. Articles constructed out of three scuffed sheets include exterior intumescent polymeric surfaces resisting the spread of combustion flames and insulating the interior surfaces from the high temperature of fire. Articles include electronic apparatus sending an emergency 911 call to a remote monitoring station. Articles are advantageously reinforced with optional rigidifying structures without article modification. Members are joined with snap together features providing an assembled article. Articles include handles for ergonomic manipulation by workers. Articles include elements amenably receiving unitization accessories. The article improvements are demonstrated in the form of industrial platforms, particularly material handling pallets.

8. An instantly thermoformed triple sheet pallet comprising:
-
a top molded sheet of plastic with an exteriorly visible flat surface developed to carry a load of product;
a bottom molded sheet of plastic with an exteriorly visible structural surface developed to distribute a load weight; and
a middle molded sheet of plastic with a top surface and a bottom surface, the top surface including upward facing projections fused to an interior surface of the top molded sheet of plastic and the bottom surface including downward facing depressions fused to an interior surface of the bottom molded sheet of plastic, and between the projections and depressions alternating walls of plastic maintaining the top molded sheet of plastic a fixed distance apart from the bottom molded sheet of plastic. - View Dependent Claims (9, 10, 11)

12. A unitary plastic pallet comprising:
-
a first thermoformed sheet with a flat load supporting surface bordered between first and second opposed sides;
a second thermoformed sheet spaced apart below the first thermoformed sheet with a plurality of depending leg structures; and
a third thermoformed sheet joining the first and second thermoformed sheets along said first and second opposed sides and with alternating upward extending structures fused to the first thermoformed sheet reinforcing the flat load supporting surface and downward extending structures fused to the second thermoformed sheet reinforcing the depending leg structures and maintaining the first thermoformed sheet a fixed distance apart from the second thermoformed sheet. - View Dependent Claims (13)

14. A triple sheet thermoplastic resin pallet comprising a top load bearing deck and a bottom load bearing support:
-
the top load bearing deck comprising three thermoplastic sheets consisting of a top side sheet with a planar load supporting surface, a lower side sheet with a plurality of depending double-walled legs and an intermediate structural sheet that maintains the top side sheet and the lower side sheet a fixed distance apart; and
the bottom load bearing support comprising three thermoplastic sheets consisting of a lower flat sheet with a surface interrupted by four openings accommodating wheels of a pallet jack, an upper sheet with ramp surfaces and between the ramp surfaces leg receiving sections to which the double-walled legs of said top load bearing deck are joined and an intermediate structural sheet that reinforces the ramp surfaces. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)
