Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
177 words
A car top load carrier comprising a rigid elongated support frame having multiple prefabricated sections, means for detachably and telescopically connecting adjacent said frame sections in longitudinal alignment and end abutment, means for removably mounting at least some of said support frame sections on the top of a vehicle and cooperating with said frame connecting means to position said frame sections in frame-defining assembled load-bearing relation, laterally spaced parallel tracks of C-shaped cross section attached to each section of said support frame at their bottom bent marginal sections and each track abutting and longitudinally aligned with an adjacent track of an adjacent frame section when said sections are connected, an elongated load carrying member, wheels journaled at one end of said load carrying member, a plurality of laterally spaced sets of rollers journaled at spaced intervals along the length of said load carrying member and adapted to traverse said tracks, said tracks retaining said rollers against release transversely from said support frame, and means for securing said load carrying member in operative position on said support frame.
Claim 2
Dependent Claim
177 words
A car top load carrier comprising a rigid elongated support frame having multiple prefabricated sections, means for detachably and telescopically connecting adjacent said frame sections in longitudinal alignment and end abutment, means for removably mounting at least some of said support frame sections on the top of a vehicle and cooperating with said frame connecting means to position said frame sections in frame-defining assembled load-bearing relation, laterally spaced parallel tracks of C-shaped cross section attached to each section of said support frame at their bottom bent marginal sections and each track abutting and longitudinally aligned with an adjacent track of an adjacent frame section when said sections are connected, an elongated load carrying member, wheels journaled at one end of said load carrying member, a plurality of laterally spaced sets of rollers journaled at spaced intervals along the length of said load carrying member and adapted to traverse said tracks, said tracks retaining said rollers against release transversely from said support frame, and means for securing said load carrying member in operative position on said support frame.
Claim 3
Dependent Claim
28 words
A car top load carrier as defined in claim 1, wherein the tracks at one end of said support frame are open to receive and release said rollers.
Claim 4
Dependent Claim
26 words
A car top load carrier as defined in claim 1, wherein each of said support frame sections has a pair of laterally spaced longitudinal tubular members.
Claim 5
Dependent Claim
80 words
A car top load carrier as defined in claim 3, wherein said section connecting means includes a rigid tube having a telescoped fit in said aligned longitudinal tubular members of adjacent sections, each of said last named tubes being fixedly secured to a tubular member of one support frame section and projecting from the end thereof, and means releasably securing the projecting portion of each of said last named tubes within the tubular member of an adjoining support frame section.
Claim 6
Dependent Claim
29 words
A car top load carrier as defined in claim 1, and a load abutment carried by and projecting above said load carrying member at the wheel mounting end thereof.
Claim 7
Dependent Claim
54 words
A car top load carrier as defined in claim 1, wherein said tracks project above said support frame with upper and lower flanges thereof positioned innermost, and the frame of said load carrying member is narrower than the spacing between said tracks and journals said rollers spaced laterally outwardly thereof to transverse said tracks.
