Abstract
A safety stanchion for supporting a safety cable includes a tapered tubular post having a lower end for attachment to a support base at an oblique angle and an upper end for supporting the safety cable. The post preferably has a wall thickness of less than 0.125 inches, is frustoconically shaped and is made out of an energy absorbing, elastic-like steel such as A595 grade steel which in cooperation with the post's wall thickness and tapered, preferably frustoconical, shape is believed to render the post capable of in elastically deforming before it fails. A unique base or base assembly for mounting a stanchion upon a structural member such as an I beam, H beam or other structural beam having flange portions is also provided.
Claims29
A safety stanchion for mounting on a structural member, said stanchion comprising:
- a post having first and second ends;
- means for supporting a safety cable at said first end of said post;
- and
- a base for attachment to said second end of said post and for mounting said post to a structural member, said base having mounting means including:
- first jaw means for engaging a first portion of the structural member;
- second jaw means for engaging a second portion of the structural member;
- and
- left and right rod assemblies cooperating with said first and second jaw means so as to draw the first and second jaw means together to clamp the structural member, said right and left rod assemblies being oriented with respect to each other so that their longitudinal axes converge.
A safety stanchion for mounting on a structural member, said stanchion comprising:
- a post having first and second ends;
- means for supporting a safety cable at said first end of said post;
- and
- a base for attachment to said second end of said post and for mounting said post to a structural member, said base having mounting means including:
- first jaw means for engaging a first portion of the structural member;
- second jaw means for engaging a second portion of the structural member;
- and
- left and right rod assemblies cooperating with said first and second jaw means so as to draw the first and second jaw means together to clamp the structural member, said right and left rod assemblies being oriented with respect to each other so that their longitudinal axes converge each rod assembly including a threaded rod and first and second internally threaded members for threadably receiving and engaging said threaded rod, said threaded rod and said internally threaded members defining threads having a pitch of between 3 and 7.5 threads per inch.
A safety stanchion for mounting on a structural member, said stanchion comprising:
- a post having first and second ends;
- means for supporting a safety cable at said first end of said post;
- a base including a sleeve for slidably receiving in said sleeve said second end of said post, said base also including mounting means for cooperating with said post to mount said post on a structural member so that the safety cable supported at said first end of said post is suspended above and to the side of the structural member;
- and
- fastening means for securing said second end of said post in said sleeve when it is slidably received therein.
An energy absorbing safety stanchion comprising:
- a tapered tubular post having first and second ends and a wall thickness of less than 0.125 inches;
- means for supporting a safety cable at said first end of said post;
- and
- a base for mounting said post to a structural member at an obliqe angle so that the safety cable supported at said first end of said post is suspended above an to the side of the structural member.
A safety stanchion comprising:
- a frustoconically shaped tubular post having a lower end for attachment to a support base and an upper end for supporting a safety cable, said upper end having an outside diameter which is less than that of said lower end, said support base cooperating with said post to mount said post on a structural member so that the safety cable supported at said first end of said post is suspended above and to the side of the structural member.
