Abstract
Abstract A connector assembly for a scaffold structure having an upright member or standard and a cross member, comprising an open-ended V or channel-shaped socket fixed to the upright member and a channel-shaped connector member fixed to an end of the cross member. In the fully assembled position, a base flange of the connector member is held, by means of a wedge element, in tight engagement with the outer surface of the socket and arms extending outwardly from the base flange, and over opposite ends of the socket, are such as to be spaced from the outer peripheral surface of the upright member. For location purposes, the free end of the uppermost arm of the connector member is formed with a downwardly depending tongue, or alternatively, the side edges of the uppermost arm are provided with downwardly depending flanges.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
158 words
A connector assembly for use in builders scaffolding of the kind hereinbefore described, comprising an open-ended socket adapted to be fixed to an upright member or standard with the open ends thereof in parallel alignment with the longitudinal axis of the upright member, a channel-shaped connector member having a base flange and upper and lower arms and adapted to be fixed by its base flange to an end of a cross member and, in use, to be positioned with its arms at opposite ends of the socket, and a wedge element provided to extend through openings in the respective arms of the connector member, and through the socket wherein, in the fully interconnected position of the assembly, the base flange of the connector member is in tight engagement with the outer surface of the socket and the ends of the arms of the connector member are in spaced relationship with the outer peripheral surface of the upright member.
Claim 2
Dependent Claim
158 words
A connector assembly for use in builders scaffolding of the kind hereinbefore described, comprising an open-ended socket adapted to be fixed to an upright member or standard with the open ends thereof in parallel alignment with the longitudinal axis of the upright member, a channel-shaped connector member having a base flange and upper and lower arms and adapted to be fixed by its base flange to an end of a cross member and, in use, to be positioned with its arms at opposite ends of the socket, and a wedge element provided to extend through openings in the respective arms of the connector member, and through the socket wherein, in the fully interconnected position of the assembly, the base flange of the connector member is in tight engagement with the outer surface of the socket and the ends of the arms of the connector member are in spaced relationship with the outer peripheral surface of the upright member.
Claim 3
Dependent Claim
24 words
An assembly as claimed in claim 1, wherein the wedge element is a flat tapered plate and is held captive in the connector member.
Claim 4
Dependent Claim
64 words
An assembly as claimed in claim 2, wherein the narrowest end of the wedge element is provided with a transverse projection and is of a size to pass through the opening in the lower arm but not through the opening in the upper arm, and the widest end of the wedge element is wider than the length of the opening in the upper arm.
Claim 5
Dependent Claim
45 words
An assembly as claimed in any one of claims 1 to 3, wherein the upper arm of the connector member is formed, on two opposite side edges thereof, with downwardly extending flanges which, in the assembled position, co-act with the outer surface of the socket.
Claim 6
Dependent Claim
47 words
An assembly as claimed in any one of claims 1 to 3, wherein the free end of the upper arm of the connector member is formed with a downwardly depending tongue which, in the assembled position, extends into the socket and co-acts with the inner surface thereof.
Claim 7
Dependent Claim
55 words
An assembly as claimed in claim 1, wherein, at the juncture of the base flange and the upper arm of the connector member, the base flange or the upper arm is outwardly radiused or deformed to avoid interference between the outer top corner of the socket and the inner top corner of the connector member.
Claim 8
Dependent Claim
14 words
An assembly as claimed in claim 1, wherein the socket is of V-shaped formation.
Claim 9
Dependent Claim
14 words
An assembly as claimed in claim 1, wherein the socket is of channel-shaped formation.
