Device for releasably fixing a tray to the extremity of a support arm

摘要

The retention device automatically couples the tray (5) to a support arm (1) via a bearing element (2) at the end of the latter, cooperating with a counter-bearing element (6) secured to the underside of the tray. The counter-bearing element has a reception groove (7) corresponding in shape to the periphery of the bearing element, inserted in the groove by horizontal movement of the tray. The bearing element has a spring-loaded catch (3) for retention of the inserted tray, released by movement against the spring bias.
