Lockable support system

Abstract

A lockable support system comprising: - a plate (100) having - a flat area (104) with a projecting central area (118) from which a plurality of arms (120) extend, - a pre-stressed movable singularity (122), - a counter plate (200) with - a disc-shaped area with a central opening (218) allowing passage of the central area (118), - a plurality of slots (220) for receiving the arms (120). Flat surfaces (234) of the teeth have a stop. The counter plate (200) has a fixed singularity (222) that can engage with the movable singularity (122) when an arm (120) of the plate comes against a stop (236). When the arms (120) pass through slots (220) and an arm (120) comes against a stop (236), an engagement surface (224) of the counter plate acts on the movable singularity (122) to move it.
