Abstract
Improvements in roofing ladders and work platforms; anti-skid devices for aiding seating and movement of a roofing worker on and over the (typically) inclined roof surface being worked; anti-skid seats, platforms and ladders for roofing work.
Claims18
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.

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.
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.
