Abstract

An improved scaffold connection is provided, comprising a first ring member having an upper side and a lower side, fixedly attachable to a vertical scaffold member; a connector body having a first end, a second end, a top, a bottom and sides, fixedly attachable at its second end to one end of a horizontal scaffold member having an upper surface, the connector body including a section for attachment of the connector body to the upper side of the first ring member, extending from the first end of the connector body; a cavity, extending through the body and opening exterior of the body at a first opening in the first end and a second opening in the second end; and a support element fixedly positioned in the cavity, the support element having a curved support surface; and a latch member, positioned in the cavity and having a first end extending through the first opening, the latch member being pivotal within the cavity and having a curved base section, matingly slidable on and supported by the support surface.

Dependent claims

An improved scaffold connection, comprising:

a. a first ring member having an upper side and a lower side, fixedly attachable to a vertical scaffold member;
b. a connector body having a first end, a second end, a top, a bottom and sides, fixedly attachable at said second end to one end of a horizontal scaffold member having an upper surface, said connector body including:
i. a means for attachment of said connector body to said upper side of said first ring member, extending from said first end of said connector body;
ii. a cavity, extending through said body and opening exterior of said body at a first opening in said first end;
and
iii. a support element fixedly positioned in said cavity said support element having a curved support surface;
and
b. a latch member, positioned in said cavity and having a first end extending through said first opening and adapted so as to be positionable below said lower side of said first ring member, said latch member being pivotal within said cavity and having a curved base section, matingly slidable on and supported by said support surface.
