Portable roof anchor

Abstract

A portable anchor for supporting a line along a side of a structure, having a beam member comprising a line support end and a counterweight end distal to the line support end, a counterweight attachable to the beam member at a counterweight location proximate the counterweight end, a support member that supports the beam member at a pivot location arranged between the line support end and the counterweight end, a line stand-off rotatably mounted to the support member and rotatable from a line deployed position and a storage position where the line stand-off guides the line away from the side of the structure in the deployed position; and an adjustable locking device that allows rotation of the support member, and selectably fixes the support member to the beam member at a selected angle.

1 . A portable anchor for supporting a line along a side of a structure, comprising:
 a beam member comprising a line support end and a counterweight end;   a counterweight attachable to the beam member at a counterweight location proximate the counterweight end;   a support member that supports the beam member at a pivot location arranged between the line support end and the counterweight end;   a line stand-off rotatably mounted to the support member and rotatable between a line deployed position and a storage position, where the line stand-off guides the line away from the side of the structure in the deployed position; and   an adjustable locking apparatus that allows rotation of the support member relative to the beam member, and selectably fixes the support member to the beam member at a selected angle.   
   
   
       2 . The portable anchor as claimed in  claim 1 , further comprising a rotatable joint arranged along the beam member, the rotatable joint configured to permit a rotation of the line support end relative to the counterweight end about an axis perpendicular to a longitudinal axis of the beam member. 
   
   
       3 . The portable anchor as claimed in  claim 1 , wherein the adjustable locking apparatus is configured to fix the support member to the beam member at any one of a plurality of predetermined angles. 
   
   
       4 . The portable anchor as claimed in  claim 1 , wherein the adjustable locking apparatus is configured to fix the support member to the beam member at any angle within a range between a first angle and a second angle. 
   
   
       5 . The portable anchor as claimed in  claim 1 , wherein the line stand-off comprises a line support bar that engages the line. 
   
   
       6 . The portable line support as claimed in  claim 5 , wherein the line support bar is affixable at a plurality of locations along the line stand-off such that a selectable degree of line stand-off from the side of the structure is provided. 
   
   
       7 . The portable line support as claimed in  claim 1 , wherein the line stand-off when rotated into a lowermost deployed position contacts a portion of the support member to prevent further lower rotation of the line stand-off, and a point of contact between the line stand-off and the line is vertically below a point of rotation of the line standoff such that a tension of the line acting against the line support bar provides a downward force to the line stand-off that operatively fixes the line stand-off in the lowermost deployed position during use without the need for a locking mechanism. 
   
   
       8 . A portable line support, comprising:
 a beam member comprising a line support end and a counterweight end;   a support member that vertically supports the beam member; and   an adjustable locking apparatus that:
 allows rotation of the support member relative to the beam member about a pivot axis, and 
 selectively fixes the support member to the beam member at a selected angle. 
   
   
   
       9 . The portable line support as claimed in  claim 8 , further comprising a rotatable joint arranged along the beam member, the rotatable joint configured to permit a rotation of the line support end relative to the counterweight end about an axis perpendicular to a longitudinal axis of the beam member. 
   
   
       10 . The portable line support as claimed in  claim 8 , wherein the adjustable locking apparatus is configured to fix the support member to the beam member at any one of a plurality of predetermined angles. 
   
   
       12 . The portable line support as claimed in  claim 8 , wherein the adjustable locking apparatus is configured to fix the support member to the beam member at any angle within a range between a first angle and a second angle. 
   
   
       13 . The portable line support as claimed in  claim 8 , further comprising a line stand-off rotably attached to the support member and comprising a line support bar that guides the line away from a side of a structure when in a deployed position. 
   
   
       14 . The portable line support as claimed in  claim 13 , wherein the line support bar is affixable at a plurality of locations along the line stand-off such that a selectable degree of line standoff from the side of the structure is provided. 
   
   
       15 . The portable line support as claimed in  claim 13 , wherein the line stand-off when rotated into a lowermost deployed position contacts a portion of the support member to prevent further lower rotation of the line stand-off, and a point of contact between the line support bar and the line is vertically below a point of rotation of the line standoff such that a tension of the line acting against the line support bar provides a downward force to the line standoff that operatively fixes the line standoff in the lowermost deployed position during use without the need for a locking mechanism. 
   
   
       16 . An apparatus for supporting a line, comprising:
 a beam member having a line support end, a counterweight end and a pivot location arranged between the line support end and the counterweight end;   a support member that supports the beam member at the pivot location; and   a line stand-off rotatably mounted to the support member, where the rotatable line stand-off guides the line away from a side of a structure when in a deployed position.   
   
   
       17 . The apparatus as claimed in  claim 16 , further comprising a rotatable joint arranged along the beam member, the rotatable joint configured to permit a rotation of the line support end relative to the counterweight end about an axis perpendicular to a longitudinal axis of the beam member. 
   
   
       18 . The apparatus as claimed in  claim 16 , wherein the line stand-off comprises a line support bar that engages the line. 
   
   
       19 . The apparatus as claimed in  claim 18 , wherein the line support bar is affixable at a plurality of locations along the line stand-off such that a selectable degree of line standoff from the side of the structure is provided. 
   
   
       20 . The apparatus as claimed in  claim 18 , wherein the line stand-off when rotated into the deployed position contacts a portion of the support member to prevent further lower rotation of the line stand-off, and a point of contact between the line support bar and the line is vertically below a point of rotation of the line standoff such that a tension of the line acting against the line support bar provides a downward force to the line standoff that operatively fixes the line standoff in the deployed position during use without the need for a locking mechanism.
