Patent

CA 2033520

The invention relates to a self opening umbrella having canopy rods (D) which can be shortened in at least a twofold manner and having a stick (1) which is telescopic in at least two stages and has on it a displaceable slider (2), to which lower struts (3) of the canopy linkage are linked, and having a drive spring (F) for raising the slider and opening the frame. In order to reduce the manual force required when pulling the slider down upon closing the umbrella canopy and also to minimise the sliding friction of the spring on the stick, the spring (F) is to supported with its lower end (F') on a rigid abutment (W) of the stick (1) and acts on a crown (20) which is displaceable axially relatively to the top of the stick.
