The upper and lower vertical pieces 452 and 453 of the latch bar housing part 45 are clamped between the fixed plate 11 and the press contact part 80a (see FIG. 13). If the screw S2 is loosened, the clamping state of the upper and lower vertical pieces 452, 453 of the latch bar housing portion 45 is canceled, and if the posture of the fixed plate 11 is in the horizontally long posture, the rotation restriction is released, and the operation portion is accommodated in the latch bar housing. A sliding movement in the left-right direction along the portion 45 is possible. Patent Document 1 can be referred to for details of the configuration and attachment of the operation unit (actuating mechanism 8). The screw S2 may be fixed to the fixing plate 11 previously stored in the latch bar storage portion 45.

In the shutter locking device configured as described above, when it is desired to provide the operation unit (the operation mechanism 8 and the operation lever 9) on the right side when viewed from the indoor side due to the layout of the room or the arrangement of furniture or the like, The screw S1 is removed from the inner front side through the opening 45A, and the second elements 51 and 61 are separated from the first elements 50 and 60 and the third elements 52 and 62, respectively. Then, the screw S2 is loosened, the third elements 52, 63 and the operating mechanism 8 are slid to the right when viewed from the room side, and the left and right sides of the second elements 51, 61 are moved to the right and left. After replacement, the both ends in the length direction are inserted into the latch bar accommodating portion 45 through the opening 45A from the front side on the indoor side, and the ends of the first elements 50 and 60 and the ends of the third elements 52 and 63, respectively. And the first element 50, 60 and the third element 52, 62 are connected to each other by the screw S1, and the operating part is fixed to the latch bar accommodating part 45 by tightening the screw S2. Thus, the position of the operation unit can be changed from the left side to the right side.

In the illustrated embodiment, the case where each latch bar is divided into three parts has been described. However, each latch bar may be divided into two parts, or four or more parts. In the case of dividing into two, each latch bar is composed of a first element and a second element. For example, a pin that connects the base end side of the second element to the operating mechanism can be detached from the outdoor side. If the pin is removed and the base end side of the second element is separated from the operating mechanism 8, the second element is separated from the first element and the operating mechanism, removed through the opening, and replaced. be able to.

The present invention can be used for a locking device of a window shutter device.
