Abstract
Abstract An attachment system for prefabricated construction, such as assembly of panels, posts, trusses, and the like, the system including double-tapered interconnective clips for installation on the respective structures to be secured together, and spacer provisions to tension the clips against each other on engagement, which consists of a vertical-sliding tightening interconnection of the clips. In further embodiments of the invention the spacers are provided as integral parts of the wall structure by recessing the clips in the wall structure, and various clip extensions are provided to stiffen the clips and to facilitate mounting the clips.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
83 words
In a fastening system including paired, symmetrical clips for attachment to members to be fastened together, for fastening said members together, each said clip comprising a U-section channel having a tapered flat base, tapered arms normal to the base, and flanges on the arms substantially normal thereto, the improvement comprising: a said clip having a lateral, tunnellike extension of a part of a said arm for receiving a fastener, thereby stiffening said clip and improving said attachment to a member to be fastened.
Claim 2
Dependent Claim
83 words
In a fastening system including paired, symmetrical clips for attachment to members to be fastened together, for fastening said members together, each said clip comprising a U-section channel having a tapered flat base, tapered arms normal to the base, and flanges on the arms substantially normal thereto, the improvement comprising: a said clip having a lateral, tunnellike extension of a part of a said arm for receiving a fastener, thereby stiffening said clip and improving said attachment to a member to be fastened.
Claim 3
Dependent Claim
44 words
A device as recited in claim 1, wherein the base taper and the taper of the arms tend in substantially opposite directions, wherein the flanges of the arms are turned outwardly, and wherein the extended part comprises a part of said arm extended inwardlY.
Claim 4
Dependent Claim
45 words
A device as recited in claim 1, wherein the base taper and the taper of the arms tend substantially in the same direction, wherein the flanges of the arms are turned inward, and wherein the extended part comprises a part of said arm extended outwardly.
Claim 5
Dependent Claim
41 words
A device as recited in claim 2 wherein the inward extension of part of an arm comprises a tunnel protrusive to the interior of the arm intermediate the length of the arm and positioned at a substantial angle to said base.
Claim 6
Dependent Claim
37 words
A device as recited in claim 4, wherein the shape of the tunnel is semiconical, with the wide portion of the cone proximate said base, and wherein said base has a hole therein aligned with the tunnel.
Claim 7
Dependent Claim
40 words
A device as recited in claim 3, wherein the outward extension of part of an arm comprises a tunnel protrusive to the exterior of the arm intermediate the length of the arm and at a substantial angle to said base.
Claim 8
Dependent Claim
25 words
A device as recited in claim 6, wherein the protrusion of the tunnel is semiconical, with the narrow portion of the cone proximate said base.
Claim 9
Dependent Claim
68 words
A device as recited in claim 1, wherein the paired clips are adapted for recessed mounting in the members to be fastened together, with each of said clips recessed for a portion of the depth of said clip, with the total depth of said recessing equaling the depth of said clips when engaged to each other, and with said extension on a clip adapted to stabilize when recessed.
Claim 10
Dependent Claim
40 words
A device as recited in claim 8, wherein said extension leaves a passage along the axis of symmetry of said paired clips when engaged, thereby adapting the clips for use with structures having utility grooves substantially aligned with said passage.
