Claims
- 1. A restraint system for protection of a building roof worker, said restraint system comprising:
- a building ascension device;
- a portable fall restraint mechanism carried by said building ascension device;
- a cable support structure connected to an extension section of said portable fall restraint mechanism; and
- a cable having a first end connected to said cable support structure, said cable having both a first section for extending upwardly from said cable support structure and a second section for extending downwardly on an opposite side of a roof, said second section terminating in a tensioning element for biasing the cable taut;
- wherein at least one of the first and second sections of said cable is adapted to connect to a harness secured to the worker, and wherein the second section of the cable is positioned around at least one rune of said second ladder to bias said second ladder in a safe leaning position to enable the worker to ascend said second ladder safely.
- 2. A restraint system according to claim 1, wherein said building ascension device comprises a first ladder, and wherein said restraint system further comprises a second ladder positioned on a side opposite said first ladder, wherein the second section of the cable is accessible by the worker when the worker uses said second ladder.
- 3. A restraint system according to claim 2, wherein the second section of the cable positioned for use by the worker enables the worker to ascend said second ladder.
- 4. A restraint system according to claim 1, wherein said building ascension device comprises a first ladder, and wherein said restraint system further comprises a second ladder providing access to the second portion of the cable from the ground.
- 5. A restraint system according to claim 1, wherein said portable fall restraint mechanism includes a resilient pad positioned for sufficient contact for stabilization.
- 6. A restraint system according to claim 1, wherein said portable fall restraint mechanism comprises:
- a ladder rung brace removably connected to a first ladder;
- said extension section pivotally connected to said ladder rung brace; and
- a resistant device pivotally connected to said extension section.
- 7. A restraint system according to claim 6, wherein at least one of said ladder rung brace, said extension section and said resistant device comprises a material from one of metal alloy, fiberglass composite, steel alloy, aluminum alloy, and plastic composite.
- 8. A restraint system according to claim 6, wherein said ladder rung brace includes a hook for positioning over a first ladder rung, and an eye bolt securing said ladder rung brace to a second ladder rung.
- 9. A restraint system according to claim 6, wherein said ladder rung brace includes a pivot fulcrum and pivot slot, and wherein said extension section pivotally rotates about the pivot fulcrum and in the pivot slot of said ladder rung brace.
- 10. A restraint system according to claim 6, wherein said cable support structure is connected to said extension section connecting a first end of a first section of the cable to said portable fall restraint mechanism.
- 11. A restraint system according to claim 6, wherein said resistant device includes a frictionally securing resilient pad.
- 12. A restraint system according to claim 11, wherein said resistant device further includes a backing plate connected to said resilient pad.
- 13. A restraint system according to claim 6, wherein said resistant device includes:
- at least two extension legs shaped in a "V" and extending from a pivotal connection of said extension section, and
- a frictionally securing resilient pad connected to each extension leg.
- 14. A restraint system according to claim 1, wherein the tensioning element comprises a weight having a mass of approximately 5 kg.
- 15. A restraint system for protection of a building roof worker, said restraint system comprising:
- a building ascension device;
- a portable fall restraint mechanism carried by said building ascension device, said portable fall restraint mechanism comprising a ladder rung brace removably connected to a first ladder, said extension section pivotally connected to said ladder rung brace, and a resistant device pivotally connected to said extension section;
- a cable support structure connected to an extension section of said portable fall restraint mechanism; and
- a cable having a first end connected to said cable support structure, said cable having both a first section for extending upwardly from said cable support structure and a second section for extending downwardly on an opposite side of a roof, said second section terminating in a tensioning element for biasing the cable taut;
- wherein at least one of the first and second sections of said cable is adapted to connect to a harness secured to the worker, and wherein said resistant device includes at least two extension legs shaped in a "V" and extending from a pivotal connection of said extension section, and a frictionally securing resilient pad connected to each extension leg.
