Abstract
Abstract A load bearing cross-slat for association with an article carrier, such as a luggage carrier, is adapted to extend transversely across a vehicle roof between a pair of carrier tracks. The cross-slat is anchored to the tracks at its ends and is cambered upward toward the center of the vehicle. The camber of the slat spaces the slat above the vehicle roof, and allows the weight of an article placed thereon to be supported at the ends of the slat and, thus, by the tracks.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
175 words
A load bearing assembly for an automotive vehicle mounted carrier of the type including a pair of spaced track members fixed to a vehicle surface and at least one cross-slat supported between said track members, the improvement wherein (a) each track member includes (1) a base portion adapted to be supported upon said vehicle surface, (2) inner and outer end walls projecting upwardly from said base portion, (3) upper wall portions projecting inwardly from said end walls and vertically spaced above said base portion, the inner ends of said upper wall portions being transversely spaced whereby the base portion, the end walls and said upper walls define an inverted T-type slot extending longitudinally of each track member, (4) a transverse opening formed through each inner end wall; (b) said cross-slat including tongue-like elements formed at each end thereof, said tongue-like elements respectively projecting through said inner wall openings and extending transversely of said track slot; and (c) common means for non-movably fastening said each tongue-like element and its associated track member to said vehicle surface.
Claim 2
Dependent Claim

A load bearing assembly for an automotive vehicle mounted carrier of the type including a pair of spaced track members fixed to a vehicle surface and at least one cross-slat supported between said track members, the improvement wherein (a) each track member includes (1) a base portion adapted to be supported upon said vehicle surface, (2) inner and outer end walls projecting upwardly from said base portion, (3) upper wall portions projecting inwardly from said end walls and vertically spaced above said base portion, the inner ends of said upper wall portions being transversely spaced whereby the base portion, the end walls and said upper walls define an inverted T-type slot extending longitudinally of each track member, (4) a transverse opening formed through each inner end wall; (b) said cross-slat including tongue-like elements formed at each end thereof, said tongue-like elements respectively projecting through said inner wall openings and extending transversely of said track slot; and (c) common means for non-movably fastening said each tongue-like element and its associated track member to said vehicle surface.
Claim 3
Dependent Claim
28 words
A load bearing assembly as set forth in claim 1 wherein said cross-slat is cambered upwardly so as to be spaced from said vehicle surface between said tracks.
Claim 4
Dependent Claim
67 words
A load bearing assembly as set forth in claim 2 wherein the outer ends of said cross-slat are partially cut away to provide said tongue-like elements and vertical wall sections at the innermost ends of said elements, said wall sections being adapted to abut against the inner end walls of said track members to maintain said cross-slat camber when a load is placed upon the cross slat.
Claim 5
Dependent Claim
26 words
A load bearing assembly as set forth in claim 1 wherein the outer ends of said cross-slat are partially cut away to provide said tongue-like elements.
