SLATTED SHUTTER SYSTEM COMPRISING AN IMPROVED SELF-LOCKING DEVICE

摘要

The invention relates to a slatted shutter system comprising an improved self-locking device. More specifically, the invention relates to a self-locking shutter system which does not require intermediate elements in the form of sections. The inventive system consists of: a pair of track guides (2) comprising interlocking openings (21) which are spaced uniformly along the length thereof; at least two contiguous slats (1) comprising complementary through holes (120, 121) which are provided in the lateral area that extends inside the track guides; and at least one locking device (3) which is mounted between the contiguous slats such as to extend through the aforementioned complementary holes in order to be locked in the interlocking openings when the slatted shutter is fully deployed or with the exertion of an upward force (F1), and which retracts from said interlocking openings (21) with the application of a downward lifting force (F2) which is exerted by means of a mechanism for lifting/lowering the shutter material.
