Abstract
Abstract A reinforced plastic pallet construction and assembly method are presented wherein multiple reinforcing bars are employed, at least some of the reinforcing bars having an exposed surface at a top surface, underneath surface or bottom surface of the pallet. In addition to functioning as a reinforcing member, the exposed surfaces of the reinforcing bars comprise an anti-skid surface for maintaining positioning of payload on the pallet or facilitating transport of the pallet, e.g., via a forklift or automated transport system. Various techniques for retaining the reinforcing bars within channels formed in the plastic pallet body are described. The reinforcing bars preferably comprise composite structural members of fiberglass reinforced plastic fabricated from a pultrusion process.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
85 words
A reinforced plastic pallet comprising: a molded plastic pallet body having multiple channels formed therein; and multiple reinforcing bars comprising composite structural members of fiberglass reinforced plastic fabricated from a pultrusion process, each reinforcing bar being sized to reside within a different channel of said multiple channels formed in the molded plastic pallet body; at least one of the multiple channels being configured such that when at least one of the multiple reinforcing bars is positioned therein, a surface of the reinforcing bar is exposed.
Claim 2
Dependent Claim
85 words
A reinforced plastic pallet comprising: a molded plastic pallet body having multiple channels formed therein; and multiple reinforcing bars comprising composite structural members of fiberglass reinforced plastic fabricated from a pultrusion process, each reinforcing bar being sized to reside within a different channel of said multiple channels formed in the molded plastic pallet body; at least one of the multiple channels being configured such that when at least one of the multiple reinforcing bars is positioned therein, a surface of the reinforcing bar is exposed.
Claim 3
Dependent Claim
21 words
The reinforced plastic pallet of claim 1, wherein each reinforcing bar has a rectangular-shaped, I-shaped, H-shaped, U-shaped or T-shaped cross-sectional configuration.
Claim 4
Dependent Claim
68 words
The reinforced plastic pallet of claim 2, wherein the molded plastic pallet body having multiple channels formed therein comprises a top deck having multiple channels formed therein, and the reinforced plastic pallet further comprises multiple pallet runners secured to a lower surface of said top deck, said multiple pallet runners operating to at least partially retain said multiple reinforcing bars within said multiple channels in said top deck.
Claim 5
Dependent Claim
72 words
The reinforced plastic pallet of claim 1, wherein said molded plastic pallet body having multiple channels formed therein comprises a top deck having multiple channels formed therein, and said reinforced plastic pallet further comprises a bottom deck secured to a lower surface of said top deck, said bottom deck secured to said top deck operating to at least partially retain said multiple reinforcing bars within said multiple channels in said top deck.
Claim 6
Dependent Claim
34 words
The reinforced plastic pallet of claim 4, further comprising means for securing said bottom deck to said top deck proximate to said multiple reinforcing bars, said bottom deck comprising a single unitary support structure.
