Abstract
Abstract A sheet metal joint for wall and ceiling panels, roofing and sidewall sheets, etc. The joint may be between wall or ceiling panels and an attaching strip, or between adjoining roofing or sidewall sheets. One member has an open tubular flange at one side edge and there is a channel at the adjacent edge portion of the other member, the channel having a restricted throat into which the open tubular flange is snapped and locked. The wall and ceiling panels are formed of spaced metal sheets with a heat and cold insulation such as polyurethane therebetween.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
100 words
A sheet metal joint for wall and ceiling panels, roofing and side wall sheets comprising two members, a channel adjacent one side edge of one member, said channel having a straight sidewall and a convex sidewall forming a restricted throat, and a springy open tubular flange at one side edge of the other member, said open tubular flange at one side edge of the other member, said open tubular flange at its widest point being larger than the restricted throat of the channel whereby said open tubular flange may be snapped into said channel to lock the two members together.
Claim 2
Dependent Claim
100 words
A sheet metal joint for wall and ceiling panels, roofing and side wall sheets comprising two members, a channel adjacent one side edge of one member, said channel having a straight sidewall and a convex sidewall forming a restricted throat, and a springy open tubular flange at one side edge of the other member, said open tubular flange at one side edge of the other member, said open tubular flange at its widest point being larger than the restricted throat of the channel whereby said open tubular flange may be snapped into said channel to lock the two members together.
Claim 3
Dependent Claim
20 words
A sheet metal joint as defined in claim 1 in which the open tubular flange is of generally oval shape.
Claim 4
Dependent Claim
30 words
A sheet metal joint as defined in claim 1 in which the channel is formed in a panel and the spriNgy open tubular flange is formed on an attaching strip.
Claim 5
Dependent Claim
35 words
A sheet metal joint as defined in claim 3 in which the attaching strip has springy open tubular flanges at opposite side edges for snapping into channels in adjacent edge portions of two similar panels.
Claim 6
Dependent Claim
148 words
A sheet metal joint for wall and ceiling panels, roofing and sidewall sheets comprising two sheet metal members, a channel adjacent one side edge of one member, said channel being formed by bending said side edge portion of the sheet to form a first sidewall, a bottom wall and a second sidewall, and then bending the terminal portion of the second sidewall toward the first sidewall and then at an angle toward the bottom wall terminating in an angular terminal flange at a point spaced from the bottom wall and the first sidewall forming a restricted throat in said channel, and a springy open tubular flange at one side edge of the other member, said open tubular flange at its widest point being larger than the restricted throat of the channel, whereby said open tubular flange may be snapped into said channel to lock the two members together.
Claim 7
Dependent Claim
148 words
A sheet metal joint for wall and ceiling panels, roofing and sidewall sheets comprising two sheet metal members, a channel adjacent one side edge of one member, said channel being formed by bending said side edge portion of the sheet to form a first sidewall, a bottom wall and a second sidewall, and then bending the terminal portion of the second sidewall toward the first sidewall and then at an angle toward the bottom wall terminating in an angular terminal flange at a point spaced from the bottom wall and the first sidewall forming a restricted throat in said channel, and a springy open tubular flange at one side edge of the other member, said open tubular flange at its widest point being larger than the restricted throat of the channel, whereby said open tubular flange may be snapped into said channel to lock the two members together.
Claim 8
Dependent Claim
22 words
A sheet metal joint as defined in claim 5 in which the edge of said terminal flange contacts the open tubular flange.
Claim 9
Dependent Claim
18 words
A sheet metal joint as defined in claim 5 in which the sidewalls of said channel are parallel.
Claim 10
Dependent Claim
21 words
A sheet metal joint as defined in claim 5 in which the sidewalls of said channel converge toward said bottom wall.
Claim 11
Dependent Claim
44 words
A sheet metal joint as defined in claim 5 including an attaching clip having means for connecting it to a support member and a curved flange on the attaching clip located within the channel and receiving the open tubular flange on the other member.
