Abstract
Abstract Bumper structure having a top member welded to a bottom member with an outstanding flange for securing a resilient rubber facing strip which contacts the outer surfaces of the members. The top and bottom members are welded so that moisture which may bleed from the weld construction drains along the inner surface of the bottom member. The formation of rust streaks on the chrome outer finish is thereby minimized.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
158 words
A channel-shaped bumper for an automobile vehicle comprising in combination: a. an upper member having a horizontal upper flange and a downwardly directed connection flange extending therefrom, b. a lower member having a horizontal lower flange and a Zmember extending upwardly therefrom having a connection flange of the upper member and an upper offset vertical flange, said downwardly directed flange being overlappingly secured to the connection flange of the Z-member to provide a channel-shaped bumper structure with an offset vertical flange member extending away from the channel at the connection, c. a weld connecting the overlapping connection flange of the upper member to the inner surface of the connection flange of the Z-member at a point below the upper offset vertical flange, whereby rust streaks emanating from the weld connection drain down the inner surface of the lower element, and d. a resilient cover strip of elastomer material fitted over the upper offset vertical flange of the Z-member.
Claim 2
Dependent Claim
158 words
A channel-shaped bumper for an automobile vehicle comprising in combination: a. an upper member having a horizontal upper flange and a downwardly directed connection flange extending therefrom, b. a lower member having a horizontal lower flange and a Zmember extending upwardly therefrom having a connection flange of the upper member and an upper offset vertical flange, said downwardly directed flange being overlappingly secured to the connection flange of the Z-member to provide a channel-shaped bumper structure with an offset vertical flange member extending away from the channel at the connection, c. a weld connecting the overlapping connection flange of the upper member to the inner surface of the connection flange of the Z-member at a point below the upper offset vertical flange, whereby rust streaks emanating from the weld connection drain down the inner surface of the lower element, and d. a resilient cover strip of elastomer material fitted over the upper offset vertical flange of the Z-member.
Claim 3
Dependent Claim
34 words
Bumper structure as set forth in claim 1, wherein said resilient cover strip is provided with a horizontal surface which is tightly fitted against the outer horizontal surfaces of the upper and lower members.
Claim 4
Dependent Claim
25 words
Bumper structures as set forth in claim 2, which further includes a bumper support bracket engaging the inner surfaces of the upper and lower members.
Claim 5
Dependent Claim
32 words
Bumper structure as set forth in claim 3, wherein said bracket is attached to said upper and lower members by bolt means extending through the downwardly directed flange and the upper member.
Claim 6
Dependent Claim
41 words
Bumper structure as set forth in claim 4, wherein said bolt means are disposed in line with the upper offset vertical flange of the Z-member, said flange being provided with a cutout portion to provide frontal access to said bolt means.
Claim 7
Dependent Claim
37 words
Bumper structure as set forth in claim 1, wherein said downwardly directed flange on the upper member is generally vertical, having its outer surface connected to the inside surface of the Z-member to form a doubler therewith.
