Claim 10

A lid lift system according to claim 7, wherein said closure member is hingedly mounted at one end to said hinge rail.

Claim 11

A lid lift system according to claim 7, wherein said lift bar is tubular steel.

Claim 12

A lid lift system according to claim 7, wherein said slide rail and said slidable members are plastic.

Claim 13

A lid lift system for reciprocating a closure member upon a bed of a truck, comprising: a lid rail assembly securably attachable to a truck bed, said lid rail assembly having a pair of edge rails substantially perpendicular to a hinge rail, said pair of edge rails secured to the truck bed; a closure member mateably engageable with said lid rail assembly; a lift bar rotatably connected at one end to said closure member and at an opposite end to said lid rail assembly, said lift bar having a lid arm from which extends at one end a curvilinear extension arm having a curvilinear section and at an opposite end an extension arm, said curvilinear extension arm pivotally mounted to one of said edge rails at the vertex of said curvilinear extension arm and said curvilinear section, and said extension arm pivotally mounted to the other of said edge rails; a lift piston actuable by an operator, said lift piston mounted at one end to one of said edge rails and at the opposite end pivotally mounted to said curvilinear section; a lift piston actuable by an operator, said lift piston mounted at one end to one of said edge rails and at the opposite end pivotally mounted to said curvilinear section; and a slide rail assembly mounted to said closure member by at least one slide rail with a channel for slidably receiving a slide member, wherein said slide member is mounted to said lid arm and slidably moves when said lift piston is actuated to reciprocate said closure member between an open position and a closed position with respect to said lid rail assembly.

Claim 14

A lid lift system for reciprocating a closure member upon a bed of a truck, comprising: a lid rail assembly securably attachable to a truck bed, said lid rail assembly having a pair of edge rails substantially perpendicular to a hinge rail, said pair of edge rails secured to the truck bed; a closure member mateably engageable with said lid rail assembly; a lift bar rotatably connected at one end to said closure member and at an opposite end to said lid rail assembly, said lift bar having a lid arm from which extends at one end a curvilinear extension arm having a curvilinear section and at an opposite end an extension arm, said curvilinear extension arm pivotally mounted to one of said edge rails at the vertex of said curvilinear extension arm and said curvilinear section, and said extension arm pivotally mounted to the other of said edge rails; a lift piston actuable by an operator, said lift piston mounted at one end to one of said edge rails and at the opposite end pivotally mounted to said curvilinear section; a lift piston actuable by an operator, said lift piston mounted at one end to one of said edge rails and at the opposite end pivotally mounted to said curvilinear section; and a slide rail assembly mounted to said closure member by at least one slide rail with a channel for slidably receiving a slide member, wherein said slide member is mounted to said lid arm and slidably moves when said lift piston is actuated to reciprocate said closure member between an open position and a closed position with respect to said lid rail assembly.
