The regulation of the opening degree of the shoji 15 by the arm portion 50 will be described. As shown in FIG. 2, when the shoji 15 is in the closed state, the longitudinal direction of the arm portion 50 is along the vertical direction. As shown in FIG. 3, when the shoji 15 moves from the closed state to the open state, the guide pin 26 moves inside the guide groove 51, and the lower end portion of the arm portion 50 is rotated outward by the guide pin 26. .. The position where the guide pin 26 comes into contact with the end portion 510 of the guide groove 51 is the maximum open state in the opening/closing range of the shoji 15. That is, the state shown in FIG. 2 is a state in which the shoji 15 is normally open most, and the opening degree of the shoji 15 is regulated by the opening degree regulation device 40.

Next, the external unlocking lock 60 for releasing the regulation of the opening degree by the arm portion 50 will be described. The external unlocking lock 60 is an operation member for releasing the opening restriction of the shoji 15 in an emergency in order for a firefighter or the like to enter the room by using the open window 1 as an emergency entrance. The external open lock 60 is an independent component separate from the arm unit 50.

The overall shape of the external open lock 60 is formed in an L shape in a side view. The external unlocking lock 60 of this embodiment includes a slide groove 61, an engagement pin 62, and an operation lever 63.

The slide groove 61 is a long hole that extends in a slender shape in the vertical direction. A screw 72 for fixing the external open lock 60 to the frame body 10 is fastened to the vertical frame 14 with the slide groove 61 inserted. The diameter of the shaft portion of the screw 72 is smaller than the width of the slide groove 61, and the head of the screw 72 is larger than the width of the slide groove 61. Detachment is prevented. The slide groove 61 allows the external unlocking lock 60 to slide vertically between a relatively lower fixed position and a relatively upper open position.

The engagement pin 62 is provided at the lower end of the external open lock 60, and axially projects from the external open lock 60 toward the vertical frame 14 side in the finding direction. The upper end of the frame-side fixing portion 55 is fixed to the vertical frame 14 by the engagement pin 62 engaging with the upper cutout portion 59 of the frame-side fixing portion 55.

The operation lever 63 of the present embodiment has a plane portion whose surface extends in the horizontal direction, and has a structure in which an operator can easily grasp the operation lever 63 in the vertical direction. The operation lever 63 may have any shape as long as it can operate the external open lock 60, and the shape thereof can be appropriately changed.

FIG. 4 is a diagram schematically showing a state of the arm portion 50 and the external open lock 60 in a state where the connection between the frame body 10 and the frame body side fixing portion 55 of the present embodiment is released. As shown in FIG. 4, by moving the external unlocking lock 60 from the fixed position (the state shown in FIG. 3) to the upper open position by holding the operation lever 63, the engagement pin 62 moves above the frame body side fixed portion 55. The frame 59 is detached from the notch 59, and the connection between the frame body side fixed portion 55 (arm portion 50) and the vertical frame 14 (frame body 10) is released.

FIG. 5: is a figure which shows typically the mode of the arm part 50 and the external open lock 60 in which the frame side fixing part 55 of this embodiment is rotating. As shown in FIG. 5, when the shoji 15 is further opened in a state where the connection between the arm portion 50 and the vertical frame 14 is released, as the arm portion 50 (shoji 15) moves away from the vertical frame 14, the axis of the screw 71 rotates about the center of rotation. As a result, the upper end of the frame side fixing portion 55 starts to rotate in the direction in which it falls to the outside of the room. At this point, the engagement of the lower cutout portion 58 of the lower end portion of the frame body side fixing portion 55 and the screw 71 is maintained.

FIG. 6 is a diagram schematically showing a state of the arm portion 50 and the external open lock 60 in a state where the regulation of the opening/closing range of the present embodiment is released. As shown in FIG. 6, when the shoji 15 is opened further than the state shown in FIG. 5, the lower cutout portion 58 of the frame body side fixing portion 55 is separated from the shaft portion of the screw 71, and the frame body side fixing portion 55. The lower end of the vertical frame 14 is disengaged. In this state, the connection between the arm 50 and the vertical frame 14 is completely released. When the arm portion 50 loses the support of the screw 71, the arm portion 50 is naturally rotated by gravity and is suspended from the guide pin 26 of the shoji 15. In this way, by operating the external open lock 60, the opening regulation of the shoji 15 by the opening regulation device 40 can be easily released.

The present embodiment described above is configured as follows.
The casement 1 includes a frame 10 arranged in an opening of a building, a shoji 15 that is openably and closably supported by the frame 10, and a frame-side fixing portion 55 that is detachably connected to the frame 10. Also, a guide pin 51 (engagement member) 26 provided on the shoji 15 has a guide groove 51 slidably coupled to the shoji 15, and an arm portion 50 for restricting an opening/closing range of the shoji 15, a frame body 10 and a frame body side fixing portion. An external open lock (external operation part) 60 capable of releasing the connection of 55. By operating the external release lock 60 from the outside of the room, the connection between the frame body side fixing portion 55 and the frame body 10 is released, and the regulation of the arm portion 50 is released while the guide pin 26 and the guide groove 51 are connected. Configured to be possible.

As a result, during normal operation, the opening and closing of the shoji 15 is restricted by the arm part 50 within a predetermined range to realize a small opening, and in an emergency, the outside open lock 60 is operated to release the restriction by the arm part 50. The shoji 15 can be wide open (fully open state). It is not necessary to release the connection between the shoji 15 and the arm portion 50, and only the connection between the frame body 10 and the frame body side fixing portion 55 needs to be released. Therefore, the restriction can be released by a simple operation and the arm portion 50 and the external release lock. The configuration of 60 can be simply put together.
Even in an opening window (joint) that does not include the external unlocking lock 60 in the configuration of the present embodiment, it is not necessary to change the connecting structure of the shoji 15 and the arm portion 50, and therefore the parts Commonization can be easily realized.

An upper cutout portion 59 is formed in the frame body side fixing portion 55, and the external open lock 60 has an engagement pin 62 that engages with the upper cutout portion 59 and connects the frame body side fixing portion 55 and the frame body 10, By the operation of the external release lock 60, the engagement pin 62 is separated from the upper cutout portion 59, and the connection between the frame body 10 and the frame body side fixing portion 55 is released.

Thereby, the operation for releasing the connection between the frame body 10 and the frame body side fixing portion 55 and the connection structure can be simplified. Further, even in an open window in which the external open lock 60 is omitted, the frame body side fixing portion 55 can be fixed to the frame body 10 only by fixing a shaft-shaped member such as a screw or a pin to the upper cutout portion 59, so that the frame body side Since it is not necessary to change the fixing portion 55, commonization of parts can be realized more easily.

The upper cutout 59 is open upward, and the connection between the frame 10 and the frame-side fixing portion 55 is released by moving the external open lock 60 upward.

Accordingly, the connection between the frame body 10 and the frame body side fixing portion 55 cannot be released unless the external unlocking lock 60 is lifted upward, so that the frame body 10 and the frame body side fixing portion 55 are unintentionally connected by an impact from the outside. It is possible to prevent the situation from being released, and it is possible to stably maintain the function of restricting the opening degree of the shoji 15 under normal conditions.

Further, in the present embodiment, since the indoor side end surface of the upper cutout 59 is inclined, by moving the external unlocking lock 60 upward, the operation lever 63 can be inclined downward toward the outside of the room. It is possible to easily disengage the engagement pin 62 from the upper cutout 59 by reducing the amount of upward movement of the external release lock 60. By adopting a two-action structure as the procedure for disengaging the engagement pin 62 from the upper cutout 59, even if a ball or the like collides with the external unlocking lock 60, the frame 10 and the frame-side fixing part 55 are separated. It is possible to more effectively prevent the situation where the connection is unintentionally released. The engaging pin 62 may be detached from the upper cutout 59 only by moving the external open lock 60 upward.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and can be appropriately modified. Further, the present invention is not limited to the configuration of the opening window of the above-described embodiment, and the opening and closing of the vertical and sideways, the opening and the like that is supported by the frame on the suspension side via a hinge, etc. It can be applied to various fittings including an opening degree restricting unit that restricts the range.
