Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
187 words
A tonneau cover attachment for a pickup truck bed having a front end wall, a tail gate and opposing sidewalls, the sidewalls having a generally horizontal top surface terminating laterally inward in a depending flange transversely not greater than the transverse width of the horizontal top surface, comprising: a flexible cover having a top and bottom surfaces and having marginal side and end edges adapted to fit over the corresponding side and end limits of a pickup truck bed; elongated rail means, coextensive with and substantially flatly overlying each sidewall top surface, including web connected parallel vertically spaced horizontal base and top walls and lateral rail sides respectively having coextensive opposing inner and outer laterally open slots; elongated fulcrum clamp means secured at its upper end portion in depending relation to the rail laterally inward side and having an upwardly open throat loosely receiving the sidewall depending flange, the clamp means having a lateral arm extending outwardly from a lower end portion of the clamp means and abutting the inward surface of the pickup sidewall; and, means for releasably fastening the cover to the rail outer slot.
Claim 2
Dependent Claim
187 words
A tonneau cover attachment for a pickup truck bed having a front end wall, a tail gate and opposing sidewalls, the sidewalls having a generally horizontal top surface terminating laterally inward in a depending flange transversely not greater than the transverse width of the horizontal top surface, comprising: a flexible cover having a top and bottom surfaces and having marginal side and end edges adapted to fit over the corresponding side and end limits of a pickup truck bed; elongated rail means, coextensive with and substantially flatly overlying each sidewall top surface, including web connected parallel vertically spaced horizontal base and top walls and lateral rail sides respectively having coextensive opposing inner and outer laterally open slots; elongated fulcrum clamp means secured at its upper end portion in depending relation to the rail laterally inward side and having an upwardly open throat loosely receiving the sidewall depending flange, the clamp means having a lateral arm extending outwardly from a lower end portion of the clamp means and abutting the inward surface of the pickup sidewall; and, means for releasably fastening the cover to the rail outer slot.
Claim 3
Dependent Claim
40 words
