Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
179 words
A frictionally engaging, protective seating and working device for use on a rooflike surface comprising, in combination: a relatively thick, resilient pad of surface adherent, non-skid, foam rubberlike material, an open centered, strong, substantially rigid, integral first frame member positioned on one side of said pad, said first frame member configured to substantially outline the shape of the pad but circumferentially inwardly positioned from the periphery of said pad whereby to be of lesser dimension with respect to said pad periphery, second frame means on the other side of said pad connected to at least portions of said first frame member through said pad, the said connections of such character as to embed the first frame member and second frame means within said pad, whereby: on the side of the pad carrying the first frame member, portions of the pad protrude both centrally outwardly and circumferentially peripherally outwardly from said first frame member, and on the side of the pad carrying the second frame means, portions of the pad protrude centrally and peripherally outwardly past said second frame means.
Claim 2
Dependent Claim
179 words
A frictionally engaging, protective seating and working device for use on a rooflike surface comprising, in combination: a relatively thick, resilient pad of surface adherent, non-skid, foam rubberlike material, an open centered, strong, substantially rigid, integral first frame member positioned on one side of said pad, said first frame member configured to substantially outline the shape of the pad but circumferentially inwardly positioned from the periphery of said pad whereby to be of lesser dimension with respect to said pad periphery, second frame means on the other side of said pad connected to at least portions of said first frame member through said pad, the said connections of such character as to embed the first frame member and second frame means within said pad, whereby: on the side of the pad carrying the first frame member, portions of the pad protrude both centrally outwardly and circumferentially peripherally outwardly from said first frame member, and on the side of the pad carrying the second frame means, portions of the pad protrude centrally and peripherally outwardly past said second frame means.
Claim 3
Dependent Claim
16 words
A device as in claim 1 wherein said pad and said first frame member are circular.
Claim 4
Dependent Claim
26 words
A device as in claim 3 as in claim 2 wherein the second frame means, as well as the first frame member, are both circular rings.
Claim 5
Dependent Claim
17 words
A device as in claim 1 wherein the pad and first frame member are rectangular in form.
Claim 6
Dependent Claim
29 words
A device as in claim 4 wherein the second frame means comprise elongate strips of length and width equivalent to two opposed sides of the first frame member rectangle.
Claim 7
Dependent Claim
19 words
A device as in claim 1 wherein the first frame member and second frame means are identical in configuration.
Claim 8
Dependent Claim
48 words
A device as in claim 1 wherein the second frame means comprise a pair of substantially identical frame members each matching and attached to a portion of the first frame member through the pad and opposed to one another symmetrically on the opposite side of the pad therefrom.
Claim 9
Dependent Claim
21 words
A device as in claim 1 wherein the first frame member and second frame means are removably bolted to one another.
Claim 10
Dependent Claim
47 words
A device as in claim 1 wherein the first frame member and second frame means are removably connected to one another in such fashion that the striking or impression of the first frame member and second frame means into the pad in said connection is variably adjustable.
Claim 11
Dependent Claim
25 words
A device as in claim 1 wherein the open centered, rigid first frame member has at least one cross beam transversely bisecting the center thereof.
Claim 12
Dependent Claim
274 words
A frictionally engaging, protective seating and working device for use on a roof like surface comprising, in combination: a relatively thick, elongate, substantially rectangular, resilient pad of surface adherent, non-skid, foam rubber-like material, a elongate, ladder-like, substantially open centered, strong, substantially rigid, integral first frame member positioned on one, normally upper side of the pad, said first frame number having a pair of elongate substantially parallel side beams with a plurality of transverse beams interconnecting same as spaced intervals along the length thereof, said first frame member configured so as to substantially outline the shape of the pad, but circumferentially inwardly positioned from the periphery of said pad, whereby to be uniformly of lesser dimension with respect to said pad periphery, second frame means on the other side of said pad connected to the elongate parallel side beams of said first frame member through said pad and comprising elongate substantially parallel side beams of like type and configuration, said pad side receiving said second frame means being normally the lower side thereof, the frame connections of such character as to embed the first frame member and the second frame means within said pad, whereby: on the upper side pad carrying the first frame member, portions of the pad protrude both centrally upwardly between the side beams and transverse members at a plurality of positions and also circumferentially peripherally outwardly from said frame member, and on the lower pad side carrying the second frame means, a continuous portion of the pad protrudes additional continuous pad portions protruding downwardly, centrally downwardly, inboard between the frame means as well as laterally, outboard of said second frame means.
Claim 13
Dependent Claim
274 words
A frictionally engaging, protective seating and working device for use on a roof like surface comprising, in combination: a relatively thick, elongate, substantially rectangular, resilient pad of surface adherent, non-skid, foam rubber-like material, a elongate, ladder-like, substantially open centered, strong, substantially rigid, integral first frame member positioned on one, normally upper side of the pad, said first frame number having a pair of elongate substantially parallel side beams with a plurality of transverse beams interconnecting same as spaced intervals along the length thereof, said first frame member configured so as to substantially outline the shape of the pad, but circumferentially inwardly positioned from the periphery of said pad, whereby to be uniformly of lesser dimension with respect to said pad periphery, second frame means on the other side of said pad connected to the elongate parallel side beams of said first frame member through said pad and comprising elongate substantially parallel side beams of like type and configuration, said pad side receiving said second frame means being normally the lower side thereof, the frame connections of such character as to embed the first frame member and the second frame means within said pad, whereby: on the upper side pad carrying the first frame member, portions of the pad protrude both centrally upwardly between the side beams and transverse members at a plurality of positions and also circumferentially peripherally outwardly from said frame member, and on the lower pad side carrying the second frame means, a continuous portion of the pad protrudes additional continuous pad portions protruding downwardly, centrally downwardly, inboard between the frame means as well as laterally, outboard of said second frame means.
Claim 14
Dependent Claim
44 words
A device as in claim 11 wherein the side beams of the first frame member on the upper side of the pad run the substantial length of the pad and the end transverse member are positioned substantially across the ends of said side beams.
Claim 15
Dependent Claim
19 words
A device as in claim 11 wherein the first frame member and second frame means are flat sheetlike material.
Claim 16
Dependent Claim
22 words
A device as in claim 13 including corrugations on the upper outer faces of the transverse members of the first frame member.
Claim 17
Dependent Claim
28 words
A device as in claim 1 wherein substantial portions of the exposed second frame means have relatively thin, resilient pads of surface adherent, non-skid foam material fixed thereto.
Claim 18
Dependent Claim
21 words

Claim 19
Dependent Claim
28 words
A device as in claim 11 wherein substantial portions of the exposed second frame means have relatively thin, resilient pads of surface adherent, non-skid foam material fixed thereto.
Claim 20
Dependent Claim
