Abstract
A coupling arrangement for coupling a guard post to a scaffold platform. The couples includes a brace for attachment to the guard post. A plug member is carried by a portion of the brace and extends perpendicular to the post. The plug includes a resilient sleeve through which extends a bolt. The bolt passes externally of the brace for external manipulation thereof. The plug member is inserted into a hollow run of the scaffold. The bolt is tightened, whereby the sleeve becomes constructed and secures itself within the rung.
Claims18
A guard post module comprising a guard post and means for coupling said post to a scaffold platform comprising:
- a bracing member attached to said post and
- a plug member carried by a portion of said bracing member and extending perpendicular to said post, said plug member having an external elongated resilient sleeve,
- said coupling means having means for axially constricting said sleeve to cause the dimensions of said sleeve to be transversely expanded, whereby said plug member may be inserted and clamped within a hollow rung of a scaffold platform.
A scaffold safety system, comprising:
- a scaffold platform having a pair of parallel side rails and a plurality of transverse hollow rungs extending through said side rails, and
- a guard post module, comprising:
- a guard post,
- a plug member connected to and extending perpendicular to said guard post, said plug member having an elongated resilient sleeve adapted to be inserted as a clearance fit within at least one of said hollow rungs, and
- means operable externally of said post for axially constricting said sleeve within said one rung thereby to transversely expand and clamp said sleeve within said one rung.
