Shutter assembly with sensor device, and related sensor device assembly
First Claim
1. A shutter assembly comprising:
- a structure which surrounds an opening;
a shutter including a plurality of laths hingedly connected together at their longitudinal edges and moveable across the opening in a direction substantially normal to the longitudinal edges between an opened position and a closed position to respectively open and close the opening;
a latch mechanism operable to retain the shutter in the closed position, the latch mechanism including at least one latch member mounted on the shutter and, for each latch member, at least one keeper mounted on the structure and which has a portion with which the respective latch member may be engaged to latch the shutter in the closed position; and
a sensor including an emitter and a detector positioned such that when the latch member is engaged the signal transmitted by the emitter is reflected by the latch member and is received by the detector, and positioned such that when the latch member is not engaged the signal from the emitter is not received by the detector.

Abstract
A shutter assembly includes a structure which surrounds an opening and a shutter including a plurality of laths hingedly connected together at their longitudinal edges and moveable across the opening in a direction substantially normal to those longitudinal edges between an opened position and a closed position to respectively open and close the opening. A latch mechanism is operable to retain the shutter in the closed position. The latch mechanism includes at least one latch member mounted on the shutter and, for each latch member, at least one keeper mounted on the structure and which has a portion with which the respective latch member may be engaged to latch the shutter in the closed position. A sensor includes an emitter and a detector positioned such that when the latch member is engaged the signal transmitted by the emitter is reflected by the latch member and is received by the detector, and positioned such that when the latch member is not engaged the signal from the emitter is not received by the detector. A related sensor device assembly is also disclosed.

12. A sensor device assembly for indicating whether an opening closeable by a shutter is open or closed, a latch mechanism being mounted on the shutter and including a latch member, and a keeper being mounted to a structure adjacent the opening, the latch member positionable in an engaged position relative to the keeper when the opening is closed by the shutter, the sensor device assembly comprising:
-
an emitter disposed in the keeper for emitting a signal; and
a detector disposed in the keeper for receiving the signal via reflection of the signal off the latch member only if the latch member is in the engaged position. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
