Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
182 words
A plastic pallet comprising: a substantially rectangular, substantially planar load bearing deck member formed from an upper sheet of thermoplastic material and a lower sheet of thermoplastic material; a first axis in the plane of said deck member extending through the center of said deck member running between two non-adjacent sides of said deck member; a second axis extending through the center of said deck member in the plane of the deck member perpendicular to said first axis; a plurality of generally non-linear bosses formed in said upper sheet of thermoplastic material depending downwardly to a predetermined depth defining a plurality of boss floors; a plurality of generally non-linear bosses formed in said lower sheet of thermoplastic material projecting upwardly to a predetermined depth and defining a plurality of boss ceilings; said upper and lower sheets of thermoplastic being fused at the intersection of said boss floors and said boss ceilings; and said bosses being arranged substantially non-symmetrically about one of said axes; said boss floors and said boss ceilings further comprising stepped boss ceilings to fuse with correspondingly stepped boss floors.
Claim 2
Dependent Claim
182 words
A plastic pallet comprising: a substantially rectangular, substantially planar load bearing deck member formed from an upper sheet of thermoplastic material and a lower sheet of thermoplastic material; a first axis in the plane of said deck member extending through the center of said deck member running between two non-adjacent sides of said deck member; a second axis extending through the center of said deck member in the plane of the deck member perpendicular to said first axis; a plurality of generally non-linear bosses formed in said upper sheet of thermoplastic material depending downwardly to a predetermined depth defining a plurality of boss floors; a plurality of generally non-linear bosses formed in said lower sheet of thermoplastic material projecting upwardly to a predetermined depth and defining a plurality of boss ceilings; said upper and lower sheets of thermoplastic being fused at the intersection of said boss floors and said boss ceilings; and said bosses being arranged substantially non-symmetrically about one of said axes; said boss floors and said boss ceilings further comprising stepped boss ceilings to fuse with correspondingly stepped boss floors.
Claim 3
Dependent Claim
22 words
The pallet according to claim 1 wherein said bosses are further arranged substantially non-symmetrically about both said first and said second axes.
Claim 4
Dependent Claim
39 words
The pallet of claim 1 wherein said bosses further comprise a mixture of major bosses and minor bosses, said major bosses having a cross sectional area that is not equal to the cross sectional area of said minor bosses.
Claim 5
Dependent Claim
31 words
The pallet of claim 3 further comprising a plurality of upwardly opening feet depending downwardly from said deck and formed from said upper and lower sheets of thermoplastic being fused together.
Claim 6
Dependent Claim
113 words
A plastic pallet comprising: a substantially planar load bearing deck member formed from an upper and lower sheet of thermoplastic; a plurality of bosses thermoformed in said upper sheet and depending to define a plurality of boss floors, a plurality of bosses formed in the lower sheet and projecting to define a plurality of boss ceilings, the bosses arranged in a non-symmetrical, non-hinge forming arrangement and; a plurality of bosses thermoformed in said deck member whereby no more than three adjacent boss centers are colinear; said bosses being further arranged in substantially non-linear distributions; said boss floors and said boss ceilings further comprising stepped boss ceilings to fuse with correspondingly stepped boss floors.
Claim 7
Dependent Claim
113 words
A plastic pallet comprising: a substantially planar load bearing deck member formed from an upper and lower sheet of thermoplastic; a plurality of bosses thermoformed in said upper sheet and depending to define a plurality of boss floors, a plurality of bosses formed in the lower sheet and projecting to define a plurality of boss ceilings, the bosses arranged in a non-symmetrical, non-hinge forming arrangement and; a plurality of bosses thermoformed in said deck member whereby no more than three adjacent boss centers are colinear; said bosses being further arranged in substantially non-linear distributions; said boss floors and said boss ceilings further comprising stepped boss ceilings to fuse with correspondingly stepped boss floors.
