Abstract
A fall arrestor device for use in connection with a building having a roof under construction. The device includes a bracket for attaching to a top plate of a vertical wall, adjacent the edge of the roof. Extending downwardly from the bracket is a leg which hangs substantially parallel to the wall. Extending upwardly from the leg is a support arm having a receptacle on a free end thereof for receipt of the upright portion of a guard rail. A bracket member extends between the leg and the support arm, and the connection of the bracket member to the support arm, and the support arm to the leg, are variable such that the receptacle presents the guard rail vertically with respect to a variety of different pitched roofs and roofs of a variety of different width overhang portions.

A guard rail support device for attachment to a wall of a building for supporting a guard rail having an upright member, the wall having an upper wall portion with a substantially horizontal portion, the device comprising:
- a bracket for attachment to the horizontal portion of the upper wall portion;
- an elongated member having an upper end connected to said bracket and a lower end below said upper end;
- a support arm having a first end connected to said lower end of said elongated member and extending upwardly therefrom, said support arm having a second end and a receptacle connected to said second end of said support arm for receiving an upright member of a guard rail;
- and
- a brace connected to said elongated member between said upper and lower ends of said elongated member and to said support arm between said first and second ends of said support arm, such that upon receipt of the upright in said receptacle, the upright extends substantially vertically upwardly from said guard rail receptacle.
A guard rail support device for attachment to a wall of a building for supporting a guard rail having an upright member, the wall having an upper wall portion with a substantially horizontal portion, the device comprising:
- attachment means for attachment to the substantially horizontal portion of upper wall portion;
- elongated support means connected to said attachment means and extending downwardly from said attachment means;
- support arm means connected to said elongated support means and extending upwardly from said elongated support means, said support arm means defining a receptacle for receiving an upright of the guard rail;
- bracing means connected to both said elongated support means and said support arm means;
- said attachment means adapted to place substantially the entire vertical load of the guard rail support device on the upper wall;
- and
- said support arm means being connectable to said elongated support means at a plurality of positions, and said bracing means being connectable to said support arm means at a plurality of different positions, such that said receptacle may receive the guard rail and support the guard rail in a plane substantially parallel to the wall.
A method for supporting an upright of a guard rail from a wall of a building, the wall having an upper wall portion with a substantially horizontal portion, the method comprising:
- providing a bracket for attachment to the upper all portion and attaching the bracket to the upper wall portion;
- providing an elongated member having an upper a lower end and connecting said upper end of said elongated member to said bracket such that said elongated member extends downwardly from said bracket;
- providing a support arm having a first and a second end and connecting said support arm first end to said elongated member lower end;
- providing a receptacle on said support arm and positioning said support arm second end such that said receptacle presents a vertically disposed receiver;
- providing a brace member and connecting said brace member between said upper and lower ends of said elongated member and said support arm between said first and second ends of such that said receiver remains substantially vertical;
- and
- inserting the upright of the guard rail in said receiver of said receptacle.
A roof restraint device for attachment to a wall of a building, the wall having an upper wall portion with a substantially horizontal portion, the device comprising:
- a bracket for attachment to the upper wall portion;
- an elongated member having an upper end connected to said bracket and a lower end;
- a support arm having a first end connected to said lower end of said elongated member and extending upwardly therefrom, said support arm having a second end and a guard rail receptacle connected to said second end of said support arm;
- a brace connected to said elongated member between said upper and lower ends of said elongated member, and connected to said support arm between said first and second ends of said support arm;
- and
- a barrier member connected to said receptacle, and said receptacle being positioned such that said barrier member extends substantially vertically upwardly from said receptacle.
