Abstract: An arch shutter having a frame with an arch frame portion, and often with a linear lower frame portion, and louvres extending from side to side of the arch portion, parallel to the linear lower frame portion, and having a frame section of predetermined width, and bevel portions formed at each end of each louvre, the bevel portions removing a portion at each end of each louvre for providing clearance for rotation of each louvre without interfering with arch frame portion, and pivot pins inserted through drillings in the frame from the exterior.

Abstract: A shutter assembly for mounting in a building fabric or window opening and having a rectangular frame and a latch mechanism and a catch plate to allow locking and unlocking of the shutter assembly in the window, in which the catch plate has a transverse groove receiving the latch mechanism, and a stop wall at a rearward end and a ramp at the forward end, and retaining pins for securing the catch plate in the window, all formed in one piece integrally.

Abstract: A shutter having a frame, hollow louvres rotatably supported in the frame, and a control bar for controlling the louvres and one-piece connector members connecting the louvres to the control bar in which the connector member has a T-member with integral rigid arms extending normal to the stem on either side for insertion into a louvre, a stem integral with the T-member and an abutment on the stem which prevents movement of the stem into the interior of the louvre and ribs within the louvre for locating the arms and assisting in providing a hinge action and attachments for attaching to a control bar.

Abstract: A shutter having a frame, and having louvres rotatably supported in the frame, and a control bar, for controlling the louvres, and having two-component connectors connecting respective louvres to the control bar, consisting of a louvre hinge member for attachment to a louvre and a control bar hinge member for, and having a louvre hinge body, a louvre plug integral with the louvre hinge body for insertion into a louvre, a concave surface on said louvre hinge body engaging said louvre which prevents twisting, a hinge opening, and having a control bar hinge body, a control bar plug, a control bar hinge pin, cooperating with said hinge opening in said louvre hinge body to provide a hinging action.

Abstract: A shutter assembly having a rectangular frame and at least two separate sections of louvres rotatably supported in the frame; at least two separate tilt control bars, for controlling at least two separate groups of louvres; links connecting respective louvres to the respective control bar; a releasable connector device for connecting and disconnecting the tilt control bars of at least two separate sections of louvres of the shutter assembly, to allow adjustment of the tilt of the louvres in all groups of the shutter assembly in unison, or each separate group of the louvres individually.

Abstract: A shutter with a frame having side members and top and bottom members, and louvres mounted between the side members, and a control for controlling and tilting the louvres, and louvre seals at the top and bottom of the frame, the louvre seals being loosely supported on the top and bottom of the frame, with support surfaces on the frame, the top frame loosely supporting the top seal in a vertically dependent position, and the bottom frame loosely supporting the bottom seal in an upright standing position, and which render the two louvre seals swingable to allow sealing contact by the top and bottom louvres, when the louvres are tilted closed, and which seals swing back to vertical when released by the louvres.
