Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
162 words
A system for attaching slabs to structural girders to form system walls or system ceilings, and comprising: a plurality of separate slabs, each slab having at least one slit extending into a side confronting one of said structural girders, each slit including a pair of spaced sidewalls and a bottom wall extending therebetween; a plurality of spaced clamping feet each having a first end portion mounted on a structural girder and having a further, curved portion extending into contact with the bottom wall of a confronting slit, each curved portion culminating in a barbed end projecting away from said bottom wall and into contact with a side wall of said respective slit enclosing said curved end portion; whereby slight pressure against each slab in the direction of said confronting structural girders is sufficient to initiate penetration of said barbed end portions through said slit sidewalls and into interior portions of said respective slabs, thereby fixedly attaching said slabs to said clamping feet.
Claim 2
Independent Claim
162 words
A system for attaching slabs to structural girders to form system walls or system ceilings, and comprising: a plurality of separate slabs, each slab having at least one slit extending into a side confronting one of said structural girders, each slit including a pair of spaced sidewalls and a bottom wall extending therebetween; a plurality of spaced clamping feet each having a first end portion mounted on a structural girder and having a further, curved portion extending into contact with the bottom wall of a confronting slit, each curved portion culminating in a barbed end projecting away from said bottom wall and into contact with a side wall of said respective slit enclosing said curved end portion; whereby slight pressure against each slab in the direction of said confronting structural girders is sufficient to initiate penetration of said barbed end portions through said slit sidewalls and into interior portions of said respective slabs, thereby fixedly attaching said slabs to said clamping feet.
Claim 3
Dependent Claim
20 words
A system according to claim 1, wherein each slit defines a sub-stantially rectangular-shaped opening extending partially through a respective slab.
Claim 4
Dependent Claim
63 words
3, A system according to claim 1, wherein pairs of adjacently disposed clamping feet are integrally joined to one another via a substantially planar fastening member extending therebetween, each fastening member including a pair of fastening lips folded about opposite end portions of a structural girder to prevent separation of said fastening member and said integrally attached clamping feet from said structural girder.
Claim 5
Dependent Claim
33 words
A system according to claim 1, wherein said clamping feet curved portions are substantially V-shaped in configuration, each substantially V-shaped portion having a corner resting on the bottom wall of a respective slit.
Claim 6
Dependent Claim
61 words
A system according to claim 3, wherein each pair of attached clamping feet have curved portions of substantially V-shaped configuration, with each V-shaped portion having a corner resting on the bottom wall of a respective slit, each pair of V-shaped portions culminating in a pair of barbs extending away from said fastening member integrally joining said pair of clamping feet together.
Claim 7
Dependent Claim
43 words
A system according to claim 5, wherein each V-shaped portion intersects a sidewall edge of a respective slit at an angle sufficient to bias an attached barb into contact with an opposite side wall as said slab is moved toward said structural girder.
Claim 8
Dependent Claim
39 words
A system according to claim 1, wherein each of said clamping feet is integrally attached to a substantially V-shaped structural girder and each of said clamping feet includes a substantially hook-shaped curved portion partially enclosed within a respective slit.
