Title:
SHUTTER ASSEMBLIES PARTICULARLY ADAPTED FOR USE ON YACHTS
Document Type and Number:
WIPO Patent Application WO/1997/034114
Kind Code:
A2
Abstract:
A shutter assembly (10) for an opening adapted to admit light and/or air. The shutter assembly utilizes laterally spaced base members (12) that define a base plane which extends across the opening. The base members may be relatively angularly disposed or parallel. A plurality of parallel, shutter-slats (30) extends between the base members, and each shutter-slat has a longitudinal reference axis (32), a mounting axis (42) and an input axis (44). Each mounting axis is disposed in transverse, parallel, spaced relation with respect to the longitudinal reference axis, and the mounting axis of each shutter-slat lies within the base plane. Pivot members (46) secure each shutter-slat to the base members for pivotal movement of each shutter-slat about its mounting axis. The input axis of each shutter-slat is disposed in transversely spaced, parallel relation with respect to the mounting axis. At least one actuator (50) which is disposed in parallel relation to at least one base member, is pivotally connected to each shutter-slat for relatively pivotal movement of the actuator about the input axis of each shutter-slat in order to simultaneously effect pivotal movement of each shutter-slat about its mounting axis.
