Adjustable Wall Mounted Walkway with Optional Handrail Attachment

Abstract

A safety parapet system for securement to the wall surfaces of building structures and which can be disposed on uneven ground that may surround the building structures includes at least two stanchions located adjacent the wall structure with each stanchion capable of receiving a drop-in safety rail post that is telescopically adjustable along the length of the stanchion for locking into place with the safety rail posts being independently adjustable on the stanchions so that a walkway can be supported in a horizontal disposition on laterally extending members of each safety rail post whether the safety parapet system is disposed on level or uneven ground. An optional handrail can be mounted to the safety rail posts for use if the worker is located six feet or more above the ground surface.

1 . A safety parapet system for placement against the wall of a building structure and for securement to the studs of the building structure for supporting a worker thereon, the safety parapet system, comprising: 
 a pair of stanchions for disposition adjacent and parallel to the wall of the building structure with each stanchion having a foot for placement on the ground surface and a plurality of through holes spaced along the length of the stanchion;    a pair of safety rail posts with each safety rail post slidably disposed on each respective stanchion for selective telescopic adjustment thereon so that the height of each safety rail post can be set at the same location on each stanchion;    each safety rail post including laterally extending members that are interconnected at their distal ends;    a locking pin for locking the safety rail post to the stanchion after the desired height of the safety rail post is determined;    a walkway for removable placement upon the laterally extending members of both safety rail posts for supporting the worker thereon;    a handrail capable of removable securement to the distal ends of the laterally extending members of the safety rail posts for use if the worker is located six feet or more above the ground surface; and    each safety rail post capable of selective and independent telescopic adjustment on the respective stanchion so that the safety rail posts can be set at the same height even if the ground surface is uneven and the foot of one stanchion is located lower on the uneven ground surface than the foot of the other stanchion.    
   
   
       2 . The safety parapet system of  claim 1  wherein each safety rail post includes a vertical member and the vertical member having a channel through which the stanchion extends thereby allowing for the slidable telescopic adjustment of the safety rail post on the stanchion.  
   
   
       3 . The safety parapet system of  claim 2  wherein the vertical member of each safety rail post includes at least one aperture that can be aligned with the through holes of the stanchion so that the locking pin can be inserted through the vertical member and the stanchion for locking the safety rail post to the stanchion.  
   
   
       4 . The safety parapet system of  claim 3  wherein the laterally extending members of the safety rail post include a horizontal member and an angled member interconnected at their respective distal ends.  
   
   
       5 . The safety parapet system of  claim 4  wherein the horizontal member and the angled member are interconnected to each other at their respective distal ends for an end socket.  
   
   
       6 . The safety parapet system of  claim 5  wherein the horizontal member includes a flat upper walkway supporting surface for placement thereon of the walkway.  
   
   
       7 . The safety parapet system of  claim 6  wherein each safety rail post includes an upper brace and a lower brace with both braces extending transverse to the stanchion and abutting the wall when the stanchion is secured to the studs of the building structure.  
   
   
       8 . The safety parapet system of  claim 7  wherein the handrail includes at least two spaced-apart handrail uprights with each upright removably insertable into the end socket of each safety rail post.  
   
   
       9 . The safety parapet system of  claim 8  wherein the handrail includes at least two rails that extend between and are attached to the handrail uprights for preventing the worker from falling off the walkway.  
   
   
       10 . A safety parapet system, comprising: 
 a pair of stanchions for securement to the wall surface of a building structure with each stanchion having a foot that rests upon the ground surface and a plurality of through holes spaced along the length of the stanchion;    a pair of safety rail posts with each safety rail post capable of slidable telescopic adjustment on the respective stanchions so that the safety rail posts can be set level with each other whether the stanchions are disposed on even or uneven ground;    each safety rail post including laterally extending members that are interconnected at their respective distal ends;    a locking pin for locking the safety rail post to the stanchion after the position of the safety rail post has been determined;    a walkway for removable placement upon the laterally extending members of the safety rail posts for supporting the worker thereon;    a handrail for removable securement to the distal ends of the laterally extending members of the safety rail posts for use if the worker is located six feet or more above the ground surface; and    each safety rail post capable of selective and independent telescopic adjustment on their respective stanchions so that the safety rail posts can be set at the same level despite the stanchions being disposed on an uneven ground surface wherein the foot of one stanchion rests on the ground surface at a position that is lower than the foot of the other stanchion.    
   
   
       11 . The safety parapet system of  claim 10  wherein each safety rail post includes a vertical member and the vertical member having a channel for receiving therein the stanchion so that the safety rail post is capable of slidable telescopic adjustment thereon.  
   
   
       12 . The safety parapet system of  claim 11  wherein the vertical member of each safety rail post includes a pair of aligned apertures that can be aligned with the through holes on the stanchion so that the locking pin can be inserted through the vertical member and the stanchion for locking the safety rail post at the desired height on the stanchion.  
   
   
       13 . The safety parapet system of  claim 12  wherein the laterally extending members of the safety rail post include a horizontal member and an angled member that are interconnected at their distal ends.  
   
   
       14 . The safety parapet system of  claim 13  wherein the horizontal member includes a flat upper walkway supporting surface for receiving and supporting thereon the walkway.  
   
   
       15 . The safety parapet system of  claim 14  wherein each safety rail post includes an upper brace and a lower brace with both braces secured to and extending transverse to the vertical member and contiguous with the wall surface when the stanchion is mounted to the building structure.  
   
   
       16 . The safety parapet system of  claim 15  wherein the handrail includes at least two spaced-apart handrail uprights with each upright removably insertable into the end socket of each respective safety rail post.  
   
   
       17 . The safety parapet system of  claim 16  wherein the handrail includes at least two spaced-apart rails that extend between and are attached to the handrail uprights for preventing the worker from falling off the walkway.
