Safety device for guardrail in use in shipyards

Abstract

A safety device for guardrail in use in shipyards, wherein the guardrail includes a plurality of stanchions constrained on the edge of a hull of a vessel and a lifeline. The device includes a plurality of rods defining an axis of extension and capable of being arranged along at least part of the guardrail, and one or more nets constrained in succession to the rods to define a continuous containment bulkhead. Each rod is detachably constrained to a respective stanchion in correspondence with at least two constraint areas mutually spaced along the extension axis to prevent translation of the rod with respect to the stanchion along at least one plane skew with respect to the guardrail.

1 . A safety device for a guardrail in use in shipyards,
 said guardrail including a plurality of stanchions attached to the edge of a vessel's hull and at least one lifeline, and   said device comprising:   a plurality of rods each defining an extension axis and designed to be arranged along at least part of said guardrail, and   one or more nets attached in succession to said rods in such a way as to define a containment bulkhead,   and   each rod is detachably attached to at least one corresponding said stanchion at least two attachment zones mutually spaced apart along said extension axis to prevent said rod moving in relation to said stanchion along at least one plane that is skew in relation to said guardrail.   
     
     
         2 . The device according to  claim 1 , comprising attachment means configured to attach each said rod to at least one corresponding said stanchion at least said attachment zones and to enable reciprocal movement, on command, between said rod and said stanchion along a direction parallel to said extension axis. 
     
     
         3 . The device according to  claim 2 , wherein said attachment means comprise a first collar and a second collar configured to be laid on said stanchion, making said attachment zones, and attached to said rod. 
     
     
         4 . The device according to  claim 3 , wherein said attachment means comprise at least one slider loosely attached to said rod in such a way that the slider can slide, on command, along said extension axis and at least one of either said first collar or said second collar is attached to said slider to make at least one loose attachment, on command, between said rod and said stanchion. 
     
     
         5 . The device according to  claim 1 , wherein one or more of said collars and said slider includes an inner surface that is rubberised to increase the friction between said rod or said stanchion and one of either said collars and said slider attached to said rod or said stanchion. 
     
     
         6 . The device according to  claim 1 , comprising at least one cable that is attached to said rods under tension to connect said rods in succession. 
     
     
         7 . The device according to  claim 6 , wherein each rod comprises at least one slot configured to house at least part of said cable. 
     
     
         8 . The device according to  claim 1 , wherein each rod defines a first end designed to face, in use, said edge and a second end opposite said first end, and said first end includes a base including material at least partially pliable and configured to come into contact with said edge to define a support attachment between said rod and said edge. 
     
     
         9 . The device according to  claim 1 , wherein said net includes at least one reinforcement portion designed to be arranged, in use, adjacent to said edge on the bottom of said containment bulkhead. 
     
     
         10 . A safety apparatus comprising a device according to  claim 1  and a stanchion consisting of an element that is at least partly tubular including a housing accessible from the outside, wherein each rod is configured to be inserted or withdrawn by sliding within said housing, said attachment means being made from said housing and said first end. 
     
     
         11 . A procedure for equipping a vessel in a shipyard for the maintenance of said vessel including a device according to  claim 1 , comprising:
 mutually attaching each said rod to a corresponding stanchion at at least said two attachment zones,   hooking said one or more nets on said rods defining said containment bulkhead.
