Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
162 words
A mechanism for raising and lowering a pivotally hinged rigid cover of a truck cargo bed where the cargo bed has side walls, an end wall and a tailgate, and the cover is hinged to the end wall to pivot vertically comprising: a. a pivotal lever arm means mounted on said truck cargo bed said lever arm means having a pivotal end and a free end, said free end contacting the rigid cover on it's underside to provide force for raising the cover and to control the lowering of the cover; b. an electric power means for pivoting said lever arm means including a winch with a cable connected to said lever arm means; and, c. an L-shaped support for supporting said electric power means, an angled bracket means fixed on said L-shaped support for supporting a pulley at a height above the pivotal end of said lever arm means, whereby said cable provides a force for pivoting said lever arm means.
Claim 2
Dependent Claim
162 words
A mechanism for raising and lowering a pivotally hinged rigid cover of a truck cargo bed where the cargo bed has side walls, an end wall and a tailgate, and the cover is hinged to the end wall to pivot vertically comprising: a. a pivotal lever arm means mounted on said truck cargo bed said lever arm means having a pivotal end and a free end, said free end contacting the rigid cover on it's underside to provide force for raising the cover and to control the lowering of the cover; b. an electric power means for pivoting said lever arm means including a winch with a cable connected to said lever arm means; and, c. an L-shaped support for supporting said electric power means, an angled bracket means fixed on said L-shaped support for supporting a pulley at a height above the pivotal end of said lever arm means, whereby said cable provides a force for pivoting said lever arm means.
Claim 3
Dependent Claim
79 words
A mechanism for raising and lowering a pivotally hinged cover as in claim 1, wherein said pivotal lever arm means is mounted on wheel wells in the cargo bed, and having rest support means on said pivotal lever arm means which rest on the wheel wells to limit the angle of said lever arm means at rest to a slight incline, with the pivot point of said pivotal lever arm means being at the lowest end of the incline.
Claim 4
Dependent Claim
41 words
A mechanism for raising and lowering a pivotally hinged cover as in claim 2 wherein said pivotal lever arm means includes a pair of lever arms with roller means on the free ends, a cross bar connecting said lever arms together.
Claim 5
Dependent Claim
31 words
A mechanism for raising and lowering a pivotally hinged planar cover as in claim 3 wherein said rigid cover has roller tracks on the underside for guiding said lever arm rollers.
