LOCKING MECHANISM FOR ROLLING SHUTTERS

摘要

Novelty: a locking mechanism for rolling shutters is disclosed. Constitution: the locking mechanism 1 made of metal or synthetic materials is adapted to the lower frame
.6 of the rolling shutter 8 and comprises one horizontal and two vertical round and square sectioned chambers interconnected with or without a rounded corner portion forming a 90 deg. angle; a bolt 2 furnished with a spring 3 is placed on the horizontal chamber to secure and unsecure via its reciprocating motion the rolling shutter 8 in the locking nests 10; balls 4 are placed inside the rounded corner portion to transmit the dynamic energy of the vertical motion into horizontal through a pin 5 operating into each chamber and being fixed on a special aluminium profile 7 uniting the rolling shutter 8 with the lower frame
6; a lamella 12 having a spring operates on the front and vertical chamber to close up the hole 13 of the bolt 2 by deactivating the locking mechanism 1 during the operation of the rolling shutter 8; a hole exists in the middle of the lamella 12 extending from the lower frame 6
. so that when the rolling shutter is closed up the hole 13 comes in a line with the diode of the bolt 2 for securing the rolling shutter inside the locking nests 10; an alarm sensor is housed in the hole 13.
