Abstract
Abstract A roof bow device for use with a vehicle including a channellike body member made from a single piece of sheet material adapted at its opposed ends for attachment to a vehicle. The body member includes a pair of oppositely disposed side walls interconnected together by a web portion with flanges extending laterally outwardly from the side walls adjacent the end remote from the web portion. The flanges each include flute-like deformations adjacent the opposed ends of the body member to provide optimum securement with the vehicle.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
132 words
A roof bow device with a vehicle comprising, a channel-like body member formed from sheet material adapted at its opposed ends for attachment to said vehicle, said body being defined by opposed side walls integrally joined at one end by a centrally disposed web portion, flange means extending outwardly from the end edges of said walls remote from said web portion, said flange means including a pair of spaced, laterally extending flange members, said walls being deformed outwardly into generally coplanar relation with respect to said web portion adjacent the opposed ends of said body member, and said flange members being reversely bent into confronting relation with respect to said walls to form fluted deformations adjacent the opposed ends of said body member for strengthening said device for attachment to said vehicle.
Claim 2
Dependent Claim
132 words
A roof bow device with a vehicle comprising, a channel-like body member formed from sheet material adapted at its opposed ends for attachment to said vehicle, said body being defined by opposed side walls integrally joined at one end by a centrally disposed web portion, flange means extending outwardly from the end edges of said walls remote from said web portion, said flange means including a pair of spaced, laterally extending flange members, said walls being deformed outwardly into generally coplanar relation with respect to said web portion adjacent the opposed ends of said body member, and said flange members being reversely bent into confronting relation with respect to said walls to form fluted deformations adjacent the opposed ends of said body member for strengthening said device for attachment to said vehicle.
Claim 3
Dependent Claim
58 words
A roof bow device in accordance with claim 1, wherein said channel member is arched in its lengthwise direction, said web portion and side walls together defining a generally U-shaped configuration, in transverse section, and said flange members being bent downwardly adjacent their terminal edges to provide skirt portions extending along the major length of said flange members.
Claim 4
Dependent Claim
35 words
A roof bow device in accordance with claim 1, wherein said flute-like deformations each comprise an outwardly opening, spirally concave depression formed by reverse twisting the material of said body member forming said flange means.
Claim 5
Dependent Claim
74 words
A roof bow device in accordance with claim 1, wherein the flange members of said fluted deformations are spaced from said web portion generally by the distance defined by the height of said side walls adjacent one end and are generally co-planar with said web portion adjacent the opposite end thereof, and said flange members being disposed in engaged relation with the confronting under side of the respective side walls adjacent said opposite end.
Claim 6
Dependent Claim
58 words
A roof bow device in accordance with claim 1, wherein each of the respective flange members adjacent each of the opposed ends of said body member are bent downwardly and inwardly in clockwise and counter clockwise directions, respectively, toward the respective of said opposed ends in a helical reverse bend of approximately 180* to provide said fluted deformations.
Claim 7
Dependent Claim
95 words
A roof bow device in accordance with claim 5, wherein the flange members of said fluted deformations include outer edges which define a generally cylindrical helix curve with the lead length (L) of the helix represented by the formula with H being substantially equal to the height of said side walls and (d) is substantially the angle between the axis of the helix and the general plane of said web portion, and the linear distance taken parallel to said web portion between the ends of each of the respective fluted deformations being approximately 1/2 L.
Claim 8
Dependent Claim
62 words
A roof bow device in accordance with claim 6, wherein said helix curve has a mid-point defined by an imaginary line perpEndicular to an imaginary linear line extending between the ends of each of said fluted deformations, said curve being substantially symmetrical on opposite sides of said mid-point, and the axis of said helix being tangent to said curve at said mid-point.
Claim 9
Dependent Claim
28 words
A roof bow device in accordance with claim 1, including attachment means formed adjacent the opposed ends of said body member for attaching said device to said vehicle.
Claim 10
Dependent Claim
27 words
A roof bow device in accordance with claim 8, including rib means formed in said body member and extending between said web portion and said attachment means.
Claim 11
Dependent Claim
72 words
A roof bow device in accordance with claim 9, wherein said attachment means includes a pair of leg-like extensions formed adjacent the opposed ends of said body member, said extensions projecting in generally perpendicular relation with respect to said web portion, and said rib means comprising a boss-like depression formed in the material of said body member which has a inner wall extending between said web portion and one of said extensions.
