摘要

A snap locking device to be used for snap locking a first member 1 such as a folding leg into at least two different angular positions in relation to a second member 12 such as a keyboard table or light box, for example, wherein the first member comprises a semi-circular ring 4 provided with at least two depressions 5 and 6, whereas the second member is a detent 11 arranged to engage with either one of the depressions, producing in this manner a snap locking effect, movement between the two positions causing resilient deformation of the ring 4.
