US 4,445,307 A · Scaffold joint for a scaffold structure

Abstract

A scaffold joint for connectng the ends of horizontal scaffold members to vertical scaffold members. Spaced pairs of ring support members are fastened to the vertical scaffold members by welding or other suitable means. End connector assemblies are fastened to the ends of the horizontal scaffold members. Each of said end connector assemblies includes an end connector member and a locking member slidably mounted thereon. Each end connector member has a pair of ring engaging portions adapted for engagement with the spaced ring support members on said vertical scaffold members. The locking members are adapted when moved to their locked position to make tight wedging contact with a ring support member, thereby causing the ring engagement portions on the end connector members to be forced into tight engagement with the ring support members to thereby lock the horizontal scaffold members to the vertical scaffold members.

A scaffold joint for connecting the ends of a horizontal scaffold member to a vertical scaffold member comprising:

a pair of ring support members fastened to the vertical scaffold member in a vertically spaced relationship;
an end connector assembly fastened to the end of a horizontal scaffold member, said end connector assembly comprised of an end connector member and a locking member slidably mounted thereon, said end connector member having a pair of ring engagement portions adapted for removable engagement with said spaced ring support members, said locking member adapted when moved to its locked position to make tight contact with one of said ring support members to thereby cause said ring engagement portions to be forced into tight contact with said ring support members.

A scaffold joint for connecting the ends of a plurality of horizontal scaffold members to a vertical scaffold member comprising:

a pair of ring support members fastened to the vertical support member in a vertically spaced relationship, said ring support members having an upstanding circular nose portion extending around the periphery thereof;
an end connector assembly fastened to the end of each of said plurality of horizontal scaffold members, each of said end connector assemblies comprised of an end connector member and a locking member slidably mounted thereon, each of said end connector members having a pair of ring engagement portions adapted for engagement with said upstanding circular nose portions on said spaced ring support members, said locking member of each end connector assembly adapted when moved to its locked position to make tight contact with one of said ring support members to thereby cause said ring engagement portions of each of said end connector members to be forced into tight engagement with said upstanding circular nose portions on said ring support members, said spaced ring support members adapted to accommodate a plurality of end connector assemblies thereon, each of said end connector assemblies capable of being independently locked and unlocked from said ring support members.
