Abstract: A louver shutter is disclosed which employs generally a plurality of louvers and a frame containing the louvers. The frame includes first and second stiles connected with first and second rails. The louvers have ends rotationally mounted to the rails and have inner and outer facing surfaces. The inner facing surface has a groove extending lengthwise between the louver ends. A plurality of decorative inserts are rigidly attached to a corresponding one of the louvers on the inner facing surface within the groove.

Abstract: Base rail (12) and arch rail (13) frame holds horizontal slats (14). The frame (12, 13) is removable from a window opening for service. The slats (14) are mounted on ladders (17) with notches (31, 32) in the slats for removal individually. The base rail (12) opens down and receives a closure piece removable for access to the mechanism. Guide plates (21) on the arch rail (13) facilitate sliding the ladder cords (18, 19) forward and rearward for tilting the slats (14) without mechanism external to the base rail (12) or arch rail (13), other than the ladder cords (18, 19) themselves. The arch rail (13) inside face is channeled to receive slat ends to obscure direct line of sight through the assembly when the slats (14) are closed. Slat ends are chamfered for tilting the slats (14) without interference with the inner surface of the arch rail (13) when the slats (14) are closed.

Abstract: In all three versions, the bottom rail has a flat, smooth bottom and does not tilt. In two versions, transverse horizontal holes receive ladder cords. In one of these versions, another horizontal hole opening at the rear of the rail extends obliquely into intersection with the transverse hole midway between the front and rear of the rail. A vertical hole extends down from the rail top to this intersection. A lift cord extends down through the vertical hole into the oblique hole where a knot on the lift cord fixes the end of the cord in the oblique hole. In too the other of these two versions, a horizontal transverse hole above each ladder cord hole receives a lift cord which extends out at the front and rear of the bottom rail. These lift cords, and the ladder cords, extend entirely up to the headrail. In this version, each slat has a notch at the front edge and rear edge, receiving the corresponding lift cord and ladder cord.
