Abstract
Abstract A clip is provided on the rafters for connecting purlins to the rafters. The clip is provided with a pair of posts having enlarged heads and each head includes a recess. A resilient tab is formed out of the clip material. A purlin is provided with a pair of keyhole-shaped openings including an enlarged opening having a slot connected thereto. The purlin is guided onto the post by a guide pin being positioned in one of the enlarged openings with the inner end of the pin in the recess of the head. The purlin is guided onto the clip with the post extending through the respective keyhole openings in the purlin and the retaining lip engages the side wall of the enlarged opening when the purlin is moved laterally on the clip whereupon the posts move into the slots of the keyhole openings and the lip snaps into locking engagement with the enlarged opening.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
169 words
A building structure comprising, a support member, a mounting plate on said support member and having a post with a head on its outer end, and a locking tab on said mounting plate adjacent said post and adapted to be resiliently deflected towards said plate and said head having a larger cross sectional area than said post, and a structural member having an enlarged opening and a slot extending from said opening such that said head on said post may be positioned through s said opening and upon said structural member being moved said post moves into said slot having a size smaller than said head thereby limiting said head against passing through it and said locking tab being resiliently depressed as said structural member is moved until it drops into said opening and engages the edge thereof to limit movement of said structural member, said post engaging the end of said slot and the locking tab engaging said enlarged opening with said post head being over said slot.
Claim 2
Dependent Claim
169 words
A building structure comprising, a support member, a mounting plate on said support member and having a post with a head on its outer end, and a locking tab on said mounting plate adjacent said post and adapted to be resiliently deflected towards said plate and said head having a larger cross sectional area than said post, and a structural member having an enlarged opening and a slot extending from said opening such that said head on said post may be positioned through s said opening and upon said structural member being moved said post moves into said slot having a size smaller than said head thereby limiting said head against passing through it and said locking tab being resiliently depressed as said structural member is moved until it drops into said opening and engages the edge thereof to limit movement of said structural member, said post engaging the end of said slot and the locking tab engaging said enlarged opening with said post head being over said slot.
Claim 3
Dependent Claim
15 words
The structure of claim 1 wherein said tab is deformed out of said mounting plate.
Claim 4
Dependent Claim
