Technical Field
The present disclosure relates generally to scaffolding and other support structures for building configurations, and more particularly to connectors for interlocking components thereof.
Background
The following paragraphs do not constitute an admission that anything discussed therein is prior art or part of the knowledge of one skilled in the art.
Canadian application numbers 650,749 and 700,184 and U.S. patent number 3,091,485 disclose locking brackets for scaffold support bars.
Us patent No. 4,470,574 discloses a support structure for building construction comprising quick acting connectors for securing the ends of the columns to the tower legs.
Canadian application No. 2,122,736 and U.S. patent No. 5,112,155 disclose a connector for assembling components of a scaffold.
Disclosure of Invention
The following summary is intended to introduce the reader to various aspects of applicants' teachings and is not intended to limit any invention thereto.
According to some aspects of the present disclosure, a connector for interlocking components may include a body extending along a longitudinal axis. The body may include a front surface, a rear end axially opposite the front surface for mounting to a first component, a radially outer surface extending along an axis between the front surface and the rear end for supporting a second component, and an internal chamber having a first inlet opening to the front surface and a second inlet opening to the outer surface. The chamber may be laterally bounded by a planar first surface and a planar second surface laterally spaced from the planar first surface. The rod may be disposed in the chamber. The lever may include a tab projecting outwardly from the first inlet and a latch adjacent the second inlet, the tab being movable relative to the body to pivot the lever between a locked position in which the latch projects radially outwardly from the second inlet to axially retain the second member between the latch and the rear end of the body, and a released position in which the latch retracts into the cavity to allow the second member to slide past the latch. The lever may include a central portion extending through the cavity between the protrusion and the latch, the central portion being laterally between and mating with the planar first surface and the planar second surface to inhibit lateral movement of the lever. A spring may be disposed in the chamber for biasing the lever to the locked position, the spring being laterally between and in close cooperation with the planar first surface and the planar second surface to inhibit lateral movement of the spring.
Other aspects and features of the teachings disclosed herein will become apparent to those ordinarily skilled in the art upon review of the following description of specific examples of the disclosure.
