Furthermore, when the movable shoji that is opened larger than the half-open position is closed, the close operation can be continued to pass through the half-open position, and the operability can be improved.
Furthermore, the contact portion of the movable shoji that has been moved abuts against the trigger, and this abutment deregulates the restricting means, and the lock pin urged by the urging means protrudes toward the shoji and engages the lock holder. Therefore, even if the user does not perform the locking operation, it is automatically locked with the opening / closing operation of the movable shoji, so that the operability can be further improved.

Further, the joinery of the present invention has a window frame having an upper frame, a lower frame, and left and right vertical frames, and a movable frame that is supported in the window frame and is slidably opened and closed between a closed position and an open position. With shoji,
The movable shoji and the window frame are provided with a locking device for locking the movable shoji. The locking device includes a lock device body provided on the window frame and a lock receiver provided on the movable shoji. And the movable shoji can be locked at at least two positions of a closed position and a semi-open position between the closed position and the open position. Corresponding to the open position, at least two lock pins provided so as to freely move toward and away from the movable obstacle, biasing means for biasing these lock pins toward the movable obstacle, and biasing of the biasing means A restricting means for restricting the lock pin to the immersive position against a force and a trigger for releasing the restriction of the restricting means are provided, and the movable shoji is provided with an opening / closing movement of the shoji. On the trigger Contact, the contact portion abutting to remove the restriction of the regulating means by engaging the locking pin receiving the lock is provided, wherein the movable shoji is operated to open toward the open position from the closed position half When it is moved to the open position, it is automatically locked by the locking device at this half-open position, and when it is moved from the open position to the closed position and moved to the half-open position, it is not locked. It may be configured to pass through a half-open position .
According to such a configuration , the movable shoji is locked by the locking device in at least two positions, ie, the closed position and the half-open position, so that a person can be prevented from entering from the opening formed by the movable shoji. As well as ensuring the performance, the indoor and outdoor spaces communicate with each other through the formed opening, so that ventilation and ventilation are possible, and a favorable indoor environment can be obtained.
In addition, if the movable shoji is opened for ventilation or ventilation, it is automatically locked at the half-open position, so that it will not open too much or forget to lock, improving security. be able to. Furthermore, when the movable shoji that is opened larger than the half-open position is closed, the close operation can be continued to pass through the half-open position, and the operability can be improved.
Furthermore, the contact portion of the movable shoji that has been moved abuts against the trigger, and this abutment deregulates the restricting means, and the lock pin urged by the urging means protrudes toward the shoji and engages the lock holder.

Further, when the upper shoji 20 is closed to the closed position by continuing the closing operation, the protrusion 752 of the slide shoe 75 contacts the one end 724A of the trigger 724 as shown in FIG. Then, the trigger 724 is rotated, the other end portion 724B of the rotated trigger 724 presses the lower end of the long hole 723A, the restriction member 723 is moved downward, and the upper lock pin 721 that is out of restriction is moved to the upper shoji 20 It is projected and moved toward the insertion hole 751 of the slide shoe 75. Therefore, as shown in FIG. 6A, the upper shoji 20 is locked by the upper lock pin 721, the slide pin 74, and the upper lock receiving portion 73 in the closed position.

On the other hand, as shown in FIG. 12, when the upper shoji 20 is moved from the closed position, the protrusion 752 of the slide shoe 75 contacts the one end 724A of the upper trigger 724 and the trigger 724 is rotated. However, the other end 724 </ b> B of the trigger 724 only moves upward along the inside of the long hole 723 </ b> A of the restricting member 723, and does not come into contact with (i.e., idle) the end of the long hole 723 </ b> A. Similarly, when the upper shoji 20 is closed and passes through the half-open position from below, the lower trigger 724 that is in contact with the protrusion 752 is rotated, but the other end of the trigger 724 is rotated. The portion 724B only moves downward along the inside of the long hole 723A of the regulating member 723, and does not come into contact with the end of the long hole 723A (is idle). As a result, when the upper shoji 20 is opened from the closed position and when the upper shoji 20 passes through the half-open position from below, the restricting member 723 does not move forward and backward, and the lock pin 721 by the restricting member 723 is moved. The claw portion 721 </ b> A is not unlocked, and the restricted state of the lock pin 721 is maintained.
As described above, when the upper shoji 20 is opened from the closed position toward the open position and moved to the half-open position, the locking device 70 automatically locks in the half-open position and closes from the open position. When it is closed toward the position and moved to the half-open position, it passes through the half-open position without being locked, and is automatically locked by the locking device 70 in the closed position.

According to this embodiment, there are the following effects.
(1) That is, by locking the upper shoji 20 opened to the half-open position by the locking device 70, it is possible to prevent the intrusion of a person from the opening O1 formed by the upper shoji 20, and to ensure crime prevention. In addition, since the indoor and outdoor spaces communicate with each other through the formed opening O1, ventilation and ventilation are possible, and a favorable indoor environment can be obtained.

(2) Since the opening O1 in a state where the upper shoji 20 is locked at the half-open position is formed at the upper part of the window frame 10, it is possible to prevent the hand from reaching the opening O1 from the outside. Crime prevention can be further improved.

(3) Since the openings O1 and O2 are formed in the upper part of the window frame 10, the outdoor scenery through the lower shoji 30 is not impaired.

(4) Also, if the upper shoji 20 is opened for ventilation or ventilation, it is automatically locked by the locking device 70 in the half-open position, so that it is too open or forgotten to be locked. No crime prevention can be improved. Furthermore, when closing the upper shoji 20 opened larger than the half-open position, the closing operation can be continued to pass without being automatically locked at the half-open position, and the operability can be improved and the closure can be closed. Since it is automatically locked by the locking device 70 at the position, the crime prevention property can be further improved.

(5) Further, the upper shoji 20 that is difficult to reach from inside the room is opened and closed with the dial 16 provided at the lower part of the vertical frame 13 and unlocked by the unlocking operation part 71 of the locking device 70 provided at the lower part of the vertical frame 13. By operating, the operability can be further improved.

(6) Further, since the upper shoji 20 is formed to be smaller in height than the lower shoji 30, the weight of the upper shoji 20 that is opened and closed for ventilation and ventilation can be reduced and the opening and closing operation can be facilitated. The operability can be improved. Furthermore, since the attachment position of the upper shoji 20 becomes a higher position of the window frame 10, it is possible to improve the crime prevention property and to make the design less visible from the room. Moreover, since the height dimension of the lower shoji 30 becomes large, an outdoor scenery can be seen more easily, a feeling of opening can be improved, and comfortability and comfort can be further improved.

(7) Further, the lock pin 721 protruding from the locking device main body 72 provided on one vertical frame 13 is engaged with the slide shoe 75 on one side of the upper shoji 20 and the slide pressed by the lock pin 721. Since the upper shoji 20 is locked by being engaged with the pin 74 and the lock receiving portion 73 of the other vertical frame 13, it is possible to lock the left and right sides with good balance and increase the locking strength. Further, since it is not necessary to provide the locking device main body 72 in both the left and right vertical frames 13, an increase in the number of parts can be prevented, the unlocking operation mechanism can be simplified, and the cost can be reduced. .
