Claim 1
Independent Claim
156 words
A system for raising and lowering a deck section of a trailer, comprising: a) a trailer floor having cutout portions which are sized and configured to correspond to the shape and configuration of said deck section; b) lift means for raising and lowering the deck section, said lift means being constructed and arranged for movement between a first position at which said deck section is lowered and flush with said trailer floor and a second position at which said lift means is vertically displaced from said trailer floor to support said deck section in a raised position, wherein a continuous flush surface is formed by said trailer floor and said deck section when said deck section is in its first position, and an upper and a lower storage level are formed when said deck section is in its second position; and c) power means for selectively moving said lift means between the raised and lowered positions.
Claim 2
Independent Claim
156 words
A system for raising and lowering a deck section of a trailer, comprising: a) a trailer floor having cutout portions which are sized and configured to correspond to the shape and configuration of said deck section; b) lift means for raising and lowering the deck section, said lift means being constructed and arranged for movement between a first position at which said deck section is lowered and flush with said trailer floor and a second position at which said lift means is vertically displaced from said trailer floor to support said deck section in a raised position, wherein a continuous flush surface is formed by said trailer floor and said deck section when said deck section is in its first position, and an upper and a lower storage level are formed when said deck section is in its second position; and c) power means for selectively moving said lift means between the raised and lowered positions.
Claim 3
Dependent Claim
69 words
A system according to claim 1 wherein said power means comprises a piston member and a cylinder member, the piston member being movably attached to the cylinder member and to the lift means so as to selectively move said lift means between the first and second positions, said power means being positioned completely beneath the level of said trailer floor when said lift means is in its lowered position.
