Abstract
An universal automatic tensioning system, for roller blinds and awnings with side rails, comprising a crossbar (2) equipped with a spring pin (6) that can move along a side guide (3) that defines the rail for the shift of the awning (1), characterized in that it includes one or more fixed clip(s) (4) that can be hooked by the spring pin (6) causing the locking of the roller blind (1); a further movement of the awning's crossbar (2) will force the spring pin (6) engaging with a mobile flap (5) that works as a sort of “bridge” for the spring pin (6), causing the unlocking of the crossbar (2), so as to realize the setting for the automatic tensioning of the roller blind (1).
Claims13
A tensioning system for tensioning a roller blind or awning, the roller blind or awning comprising a crossbar that is able to move in a first direction and in a second direction that is opposite to the first direction, the system comprising:
- a first spring pin;
- and
- a first clip comprising;
- a protrusion configured to cooperate with the first spring pin to inhibit movement of the roller blind or awning in the first direction to enable tensioning of the roller blind or awning when the crossbar and the first spring pin are in a tensioning position;
- and
- a bridge configured to pivot between a first position, whereby the bridge engages the protrusion to allow the crossbar and the first spring pin to move past the protrusion in the first direction towards a released position, and a second position, whereby the bridge is spaced from the protrusion when the first spring pin is the tensioning position;
- wherein the first spring pin is configured to engage and pivot the bridge from the second position to the first position to allow the crossbar to move in the first direction towards the released position;
- wherein the protrusion and the bridge are configured to cause the first spring pin to move against a bias of the first spring pin.
