ABSTRACT:
An umbrella has a mechanism for latching and releasing a slider (8) which tuates the umbrella canopy framework as it slides to and fro along a stick (12). The slider is fixed in the closed position by means of a latching bolt (18) which is mounted in a handle (1) and has a latching nose engaging in a notch (8b) in a guide sleeve (8c) of the slider. The slider is released by pressing a button (15) which causes the bolt (18) to slide transversely to the axis (X) of the stick against the action of a spring (17).
