Claim 2

Independent Claim 282 words

An apparatus for attaching a cover for an open-topped vehicle enclosure, such as a pickup truck bed, said enclosure having a plurality of side walls, each side wall including an outer wall, a top wall extending substantially horizontally inwardly from said outer wall, and an inner wall projecting downwardly from an inner edge of said top wall, said apparatus for attaching a cover comprising: at least one rail member, having a bottom surface configured to rest on an upper surface of said top wall; at least one cover attachment member, removably affixable to said at least one rail member, for engaging a peripheral portion of the cover; at least one upper clamp member interlockingly engageable with said at least one rail member; at least one lower clamp member configured to grippingly receive a lower edge of said inner wall of said side wall; said at least one upper clamp member and said at least one lower clamp member being operably engageable and vertically adjustable relative to each other, to enable said at least one upper clamp member to press said at least one rail member downwardly onto said top wall of said side wall and enable said at least one lower clamp member to push upwardly against said lower edge of said inner wall of said side wall, so as to grasp or release said inner wall and at least a portion of said top wall of said side wall vertically therebetween to clamp said at least one rail member onto said top wall of said side wall; and means for vertically adjusting said at least one upper clamp member and said at least one lower clamp member relative to each other.

Claim 3

Dependent Claim 65 words

The apparatus for attaching a cover according to claim 1, further comprising: cushion means operably disposed along said bottom surface of said at least one rail member to preclude damage to said top wall of said side wall when said at least one upper clamp member and said at least one lower clamp member are adjusted to grip said top wall and said inner wall.

Claim 4

Claim 5

Dependent Claim 39 words

The apparatus for attaching a cover according to claim 1, wherein said at least one lower clamp member further comprises: a resilient cushion member configured to deformably receive said lower portion of said inner wall of said side wall.

Claim 6

Dependent Claim 67 words

The apparatus for attaching a cover according to claim 1, wherein said at least one cover attachment member comprises: a clip member interlockingly and removably engageable with said at least one rail member; and a male snap member affixed to said clip member, said male snap member being separably engageable with any of a plurality of female snap members arranged along a peripheral region of said cover.

Claim 7

Dependent Claim 128 words

The apparatus for attaching a cover according to claim 1, wherein said means for adjusting said at least one upper clamp member and said at least one lower clamp member relative to each other comprises: a bolt; a bolt receiving aperture extending vertically through said at least one upper clamp member; and a threaded bore disposed vertically within said at least one lower clamp member, said bolt receiving aperture and said threaded bore being aligned when said at least one upper clamp member and said at least one lower clamp member are engaged, said at least one upper clamp member and said at least one lower clamp member being drawn together when said bolt is passed through said bolt receiving aperture, screwed into said threaded bore and tightened.

Claim 8

Dependent Claim 89 words

The apparatus for attaching a cover according to claim 3, further comprising: at least one attachment channel operably arranged within each of said at least two rail members to extend longitudinally throughout said at least one rail member to open on at least one end thereof; and at least two attachment members emanating from a central portion of said at least one corner member, perpendicularly relative to each other, each of said at least two attachment members being configured to be received within said at least one attachment channel.

Claim 9

Dependent Claim 58 words

The apparatus for attaching a cover according to claim 7, further comprising: means for affixing said at least two rail members to said at least one corner member, when each of said at least two attachment members have been received by said each said at least one attachment channel in each of said at least two rail members.

Claim 10

Dependent Claim 68 words

The apparatus for attaching a cover according to claim 1, comprising: said at least one upper clamp member having two downwardly projecting walls, said walls being arranged in substantially parallel spaced relationship; said at least one lower clamp member having an upwardly projecting wall, said upwardly projecting wall being configured to closely fit slidingly between said two downwardly projecting walls of said at least one upper clamp member.

Claim 11

Dependent Claim 55 words

The apparatus for attaching a cover according to claim 1, wherein said apparatus further comprises: means for enabling said at least one rail member, said at least one upper clamp member, and said at least one lower clamp member to cooperate to clamp said at least one rail member onto top walls having varying widths.

Claim 12

Dependent Claim 60 words

The apparatus for attaching a cover according to claim 1, wherein said apparatus further comprises: at least one cross bar member having two ends extending between opposed side walls of said open-topped vehicle enclosure, said ends of said at least one cross bar member being mounted on respective upper clamp members engaging rail members clamped onto said opposed side walls.

Claim 13

Dependent Claim 41 words

The apparatus according to claim 11 wherein said at least one cross bar member comprises: an elongated upwardly convex-shaped support member extending through said cover at positions adjacent its ends, and extending above said cover for substantially all of its length.

Claim 14

Dependent Claim 31 words

The apparatus according to claim 11 wherein said at least one cross bar member comprises: an elongated, upwardly concave-shaped support member extending entirely beneath said cover for all of its length.
