Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
137 words
A slide clip adapted for connecting a curtain wall stud, the stud having a web, a flange perpendicular to the web, and a return lip perpendicular to the flange, to the load bearing framework of a building, said clip comprising a strut, a pair of congruent fins integral with, spaced apart by, and extending laterally from the strut, said strut having a slot therein which extends into each of the fins, each fin having a notch therein which is a continuation of said slot, and a pair of convergent strips cut from but integral with the strut which protrude into the slot to form a clamp adapted to frictionally engage the lip of the stud, said clamp being sufficient to support the weight of the clip but insufficient to resist a vertical force applied to the clip.
Claim 2
Dependent Claim
137 words
A slide clip adapted for connecting a curtain wall stud, the stud having a web, a flange perpendicular to the web, and a return lip perpendicular to the flange, to the load bearing framework of a building, said clip comprising a strut, a pair of congruent fins integral with, spaced apart by, and extending laterally from the strut, said strut having a slot therein which extends into each of the fins, each fin having a notch therein which is a continuation of said slot, and a pair of convergent strips cut from but integral with the strut which protrude into the slot to form a clamp adapted to frictionally engage the lip of the stud, said clamp being sufficient to support the weight of the clip but insufficient to resist a vertical force applied to the clip.
Claim 3
Dependent Claim
150 words
In a building having a load bearing skeletal framework of vertical columns and horizontal beams; a plurality of spaced-apart curtain wall studs juxtaposed with the beams, each stud having a lip perpendicular to a beam; and a plurality of slide clips, each clip comprising a strut which rests astride a lip of a stud and is joined to a beam and a pair of congruent fins integral with, spaced apart by, and extending laterally from the strut; an improved slide clip which comprises: a strut having a slot therein which extends into each of the fins, each fin thereby having a notch therein, and a detent which protrudes from at least one lateral margin of the slot toward the opposite margin and which engages the stud lip, said engagement being frictionally sufficient to support the weight of the clip but insufficient to resist a vertical force applied to the clip.
Claim 4
Dependent Claim
150 words
In a building having a load bearing skeletal framework of vertical columns and horizontal beams; a plurality of spaced-apart curtain wall studs juxtaposed with the beams, each stud having a lip perpendicular to a beam; and a plurality of slide clips, each clip comprising a strut which rests astride a lip of a stud and is joined to a beam and a pair of congruent fins integral with, spaced apart by, and extending laterally from the strut; an improved slide clip which comprises: a strut having a slot therein which extends into each of the fins, each fin thereby having a notch therein, and a detent which protrudes from at least one lateral margin of the slot toward the opposite margin and which engages the stud lip, said engagement being frictionally sufficient to support the weight of the clip but insufficient to resist a vertical force applied to the clip.
