Locking Device for Inserts in Tubing

This article relates generally to devices for mechanically connecting structural elements and more particularly to a mechanism for locking tubular elements together.

Fig. 1 shows the elements of a locking mechanism 1 which includes a pressure pad 2, a clamp 3 and a screw 4. Pressure pad 2 has a ramplike surface 5 against which the rounded bottom of clamp 3 is forced as screw 4 is tightened in a threaded hole 6 in clamp 3.

The latter is normally mounted on a fixed surface and engages hole 6 in clamp 3 via a slot 7 in pad 2.

Figs. 2A and 2B show a front and side view, respectively, of mechanism 1 when it is used to clamp two tubular elements together. In these figures, mechanism 1 is used to hold a channel 8 within a tubular element 9. The bottom of pressure pad 2 extends through a hole 10 in channel 5 and is forced against a wall 11 of element 9 when the bottom of clamp 3 is drawn against surface 5 of pressure pad 2 by turning screw 4 in hole 6.

As screw 4 is turned, the flat upper portion 12 of clamp 3 is forced against an upper wall 13 of channel 8 to provide a pressure point against an adjacent wall of element 9. When screw 4 is tightened down, a flange 14 is forced against an adjacent outer wall of element 9, providing another pressure point.

Mechanism 1 is placed in channel 8 assembled and, when channel 8 is inserted into element 9, the depth of a slot 15 in element 9 determines the final positioning of mechanism 1. Loosen...
