Adjustable safety rail barricade for roofs

Abstract

A post support assembly for an adjustable safety rail barricade is comprised of a universal flat attachment base plate to which a post is secured. The post support has a post connector pivotally connected to a guide bracket. The post connector has an open top end to receive a post therein in a detachably securable fashion. The flat attachment base plate has a pair of opposed side connecting arms disposed on opposed sides of a central connecting arm. At least two spaced-apart incline slots are provided in the side and central connecting arms and are all inclined in a common direction and at a common angle and have a lower open end. The inclined slots in the side connecting arms are spaced apart at predetermined distance. Preferably, but not exclusively, the post support is for a safety rail barricade to be used by roofers.

       2 . A post support assembly for an adjustable safety rail barricade as claimed in  claim 1  wherein said guide bracket is comprised by a pair of guide flanges disposed parallel to one another and projecting outwardly and transverse to said flat attachment base plate, said post connector being pivotally secured between said pair of guide flanges. 
   
   
       3 . A post support assembly for an adjustable safety rail barricade as claimed in  claim 2  wherein said post connector and said guide flanges provides for pitch adjustment of said post received in said connector, said pair of guide flanges being provided with arresting means to arrest said post connector at a desired angle between said pair of guide flanges. 
   
   
       4 . A post support assembly for an adjustable safety rail barricade as claimed in  claim 3  wherein said guide flanges are each provided with an arcuate outer edges extending from said flat attachment base plate to a right angle rear connecting wall, said arresting means being provided by serrations formed along said arcuate outer edge in transverse alignment with one another to constitute spaced-apart pairs of serrations, said post connector being a tubular connector having opposed connector pins projecting from opposed sides thereof for removal engagement with selected ones of said pairs of serrations, a pair of opposed vertical slots in said opposed sides of said tubular connector spaced below said connector pins for the passage of a pivot pin therethrough and connected between said guide flanges. 
   
   
       5 . A post support as claimed in  claim 1  wherein said flat attachment base plate is a metal plate of triangular shape and defined by integrally formed flat metal arms, there being a straight arm and a pair of angled arms extending from a respective end of said straight arm to an apex area of said triangular shape base, said central connecting arm extending from said apex area to mid-length of said straight arm and defining an extension portion beyond said straight arm, said slots of said central connecting arm being provided in said extension portion, and wherein said straight arm on opposed sides of said central arm constitutes said side connecting arms. 
   
   
       6 . A post support assembly for an adjustable safety rail barricade as claimed in  claim 5  wherein said post support assembly is connected to said central connecting arm with said pair of guide flanges extending from said apex area and along a portion of said central connecting arm. 
   
   
       7 . A post support assembly for an adjustable safety rail barricade as claimed in  claim 1  wherein said safety rail barricade is a roof barricade comprised of at least two of said post supports and two of said posts, each said post having one or more brackets for supporting a rail therebetween, said inclined slots in said side connecting arms having their open ends along a lower edge of said pair of opposed side connecting arms and along a side edge of said central connecting arm. 
   
   
       8 . A post support assembly for an adjustable safety rail barricade as claimed in  claim 1  wherein said predetermined distance is substantially equal to a roof shingle flap width whereby to receive in said inclined slots roofing nails used to secure asphalt shingles and with said nails disposed in said slots of one of said side connecting arms into a roof sheeting material with said nails in said connecting arm being concealed by flaps of a shingle sheet secured thereover on said roof sheeting. 
   
   
       9 . A post support assembly for an adjustable safety rail barricade as claimed in  claim 8  wherein said central connecting arm is secured along a side edge of said roof sheeting material by roofing nails, said connecting arm extending under an outer side portion of said shingle sheet. 
   
   
       10 . A post support assembly for an adjustable safety rail barricade as claimed in  claim 8  wherein said central connecting arm is secured over said roof sheeting material by roofing nails, said connecting arm extending under said shingle sheet. 
   
   
       11 . A post support assembly for an adjustable safety rail barricade as claimed in  claim 7  in combination with a flat elevated roof or platform, said flat attachment base plate of said at least two of said supports being secured on said flat elevated roof adjacent outer edges of said flat roof or platform, said post connector being angulated transversely to said base plate wherein to support posts therein, and at least one rail between pairs of said posts, said rail being supported by said one or more brackets. 
   
   
       12 . A post support assembly for an adjustable safety rail barricade as claimed in  claim 7  in combination with a flat elevated roof or platform, said platform having an outer vertical peripheral side wall, said flat attachment base plate of said at least two of said post supports being secured to said outer vertical peripheral side wall with said side connecting arms aligned along an outer edge of said flat elevated roof or platform, said post connector being angulated to lie substantially parallel to said base plate wherein to support posts extending transversely upwards of said flat elevated roof or platform, and at least one rail between pairs of said posts, said rail being supported by said one or more brackets.
