Abstract
Abstract A roofing safety device, adapted to be used in connection with substantially all roof configurations comprises an upright support, adapted to be secured to the roof of a building, having at least one self-braking mechanism and cable assembly attached thereto. Disposed at the free end of the cable is a fastening device which may be secured to one of a plurality of heavy rings secured to a belt. The plurality of rings provided on the belt enables the worker to attach the cable of the self-braking mechanism to either side of his body, thereby allowing the worker to perform his task on the roof without being chafed by the cable. A pair of stabilizing struts, each having a rectangular foot at the distal ends thereof which are rotatable about a pair of orthogonal axes enables the device to conform to substantially any rooftop configuration. The ability of the safety device to be used in connection with virtually all rooftops, combined with the non-irritating manner in which the device may be secured to the worker increases the likelihood that the device will be used habitually, so as to reduce the number of roofing injuries and deaths.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
118 words
A roofing safety device, comprising: an axially elongated support member, having a top end and a bottom end; at least one safety mechanism attached to said support member, said safety mechanism attachable to a worker on a roof so as to prevent said worker from falling off said roof; at least three axially elongated elements for bracing or stabilizing said support member, each having an inner end and an outer end, said inner end attached to said support member; and at least three feet, one foot being secured to each of said outer ends of said axially elongated elements and attachable to said roof or adjacent surface, at least two of said feet being rotatable about non-parallel axes.
Claim 2
Dependent Claim
118 words
A roofing safety device, comprising: an axially elongated support member, having a top end and a bottom end; at least one safety mechanism attached to said support member, said safety mechanism attachable to a worker on a roof so as to prevent said worker from falling off said roof; at least three axially elongated elements for bracing or stabilizing said support member, each having an inner end and an outer end, said inner end attached to said support member; and at least three feet, one foot being secured to each of said outer ends of said axially elongated elements and attachable to said roof or adjacent surface, at least two of said feet being rotatable about non-parallel axes.
Claim 3
Dependent Claim
15 words
A roofing safety device, as defined by claim 1, wherein said safety mechanism is self-braking.
Claim 4
Dependent Claim
21 words
A roofing safety device, as defined by claim 2, wherein said safety mechanism is a spring-loaded spool and cable safety block.
Claim 5
Dependent Claim
37 words
A roofing safety device, as defined by claim 1, wherein said safety mechanism is attached to an arm which extends radially outward from the top end of said support member, said arm being rotatable about said support.
Claim 6
Dependent Claim
28 words
A roofing safety device, as defined by claim 1, further comprising an additional foot secured to the bottom end of said support member and attachable to said roof.
Claim 7
Dependent Claim
17 words
A roofing safety device, as defined by claim 5, said feet having a flat and rectangular base.
Claim 8
Dependent Claim
105 words
A roofing safety device, as defined by claim 1, further comprising: at least two L-shaped spacers, one of said L-shaped spacers being secured to each of said outer ends of said axially elongated elements having feet rotatable about nonparallel axes, each of said L-shaped spacers having a cylindrical sleeve portion, rotatable about said axially elongated element, and a tongue portion, extending radially outwardly from said sleeve portion, said tongue portion secured between a pair of raised plates, extending perpendicularly upward from each of said feet, said tongue portion allowing said foot to rotate about an axis perpendicular to the axis of said axially elongated element.
Claim 9
Dependent Claim
39 words
A roofing safety device, as defined by claim 1, further comprising: a belt securable to the body of a worker on said roof; and a means for attaching said safety device to said belt at a plurality of locations.
Claim 10
Independent Claim
104 words
A method of improving the safety of a worker on a roof comprising: aligning a foot of an axially elongated support member of a roofing safety device with a surface of a roof; securing the foot of one axially elongated element attached to said support member to said surface of a roof or to an adjacent surface; securing the feet of at least two additional axially elongated elements attached to said support member to said surface of a roof or to an adjacent surface, said feet being rotatable about non-parallel axes; and attaching said worker to a safety mechanism attached to said support member.
Claim 11
Independent Claim
104 words
A method of improving the safety of a worker on a roof comprising: aligning a foot of an axially elongated support member of a roofing safety device with a surface of a roof; securing the foot of one axially elongated element attached to said support member to said surface of a roof or to an adjacent surface; securing the feet of at least two additional axially elongated elements attached to said support member to said surface of a roof or to an adjacent surface, said feet being rotatable about non-parallel axes; and attaching said worker to a safety mechanism attached to said support member.
Claim 12
Dependent Claim
26 words
A method of improving the safety of a worker on a roof, as defined by claim 9, wherein said feet are secured to a support beam.
Claim 13
Dependent Claim
41 words
A method of improving the safety of a worker on a roof, as defined by claim 9, wherein at least one of said feet of said axially elongated elements attached to said support member is secured to a substantially vertical wall.
