Abstract
Three elongate members such as rods or tubes forming mutually perpendicular uprights transoms and ledgers in a scaffolding structure are interconnected by engagement of a bracket carried at one end of a first (horizontal) member in a socket provided in a second (upright) member, a third horizontal member being engaged between the end and the second member and retained in position by a wedge element. The wedge element is jammed in position by tightening a clamping nut, and use may be made of standard pipes such as scaffolding tubes.
Claims6
A connector system for interconnecting three elongate members comprising:
- a first elongate member;
- a support bracket attached at one end of said first elongate member;
- engagement means on said bracket engaged with a second elongate member;
- and
- a bearing face on said bracket engaged by a third elongate member when the latter is located between the second member and the said end of the first member,
- wherein the improvement comprises:
- a collar element receiving the one end of said first member and having a retaining part which fits over the bracket and a wedge part which is engaged between said third member and the said one end of the first member, the axis of the collar being substantially parallel to that of the first member, and
- a screw-threaded clamping bolt threaded in the retaining part and engaging the opposite face of the bracket from said bearing face,
- whereby upon the tightening of the bolt against the bracket the wedge part of the collar is drawn between the third member and the said one end of the third member to clamp said members relatively to each other.
A scaffolding system comprising first, second and third elongate scaffolding members and connecting means interconnecting said members, said connecting means comprising:
- a support bracket attached at one end of said first elongate member;
- engagement means on said bracket engaging said second elongate member to support the first member from the second member;
- a bearing face on said bracket engaged by said third elongate member, the latter being located between the second member and one end of the first member;
- and
- wherein the improvements consist in:
- a collar element receiving the one end of said first member and having a retaining part which fits over the bracket and a wedge part which is engageable between said third member and the said one end of the first member, the axis of the collar being substantially parallel to that of the first member, and
- a screw-threaded clamping bolt threaded in the retaining part and engaging the opposite face of the bracket from said bearing face,
- whereby upon the tightening of the bolt against the bracket the wedge part of the collar is drawn between the third member and the said one end of the first member to clamp said members relatively to each other.
