1,019,021. Hinges and pivots. L. M. J. BALFOUR. May 10, 1962 [Feb. 13, 1961], No. 5332/61. Heading E2F. A pivotal joint connecting two members 10 made of thin material comprises a cylindrical bush 15 received partly in each of two correspondingly shaped opposed co-axial recesses 11 pressed out of the material, and spigots (formed e.g. by the opposite ends of a pin 14) which project co-axially from the ends of the bush through holes 12 in the members and serve to hold them together, the length of the bush being at least as great as the sum of the depths of the recesses so that its ends engage the bottoms of the recesses. |
