The sub-lever 13 is for enabling the operation lever 12 to be operated when the lock is released by the operation lever 12 described above. The sub-lever 13 is formed in a vertically long rectangle when viewed from the indoor side, and on the side in contact with the side wall 11c, A concave surface 13a having a circular arc cross section is formed so as to follow the shape of 11c.
The lock release plate 15 is formed in a substantially disc shape, and is attached to the center portion thereof so as to be rotatable around the pin 16. A flat plate-like connecting portion 15 a is formed on the left side of the unlocking plate 15 and is connected to the concave surface 13 a of the sub lever 13. Thereby, the sub lever 13 moves up and down with the rotation of the lock release plate 15, while the lock release plate 15 rotates when the sub lever 13 moves up and down.
A plate-like curved member 25 that is curved along the arc shape of the side wall 11c is attached to the connecting portion 15a inside the side wall 11c. It is slidable along the side wall 11c with the side wall 11c being sandwiched between the outer peripheral surface of the bending member 25 and the concave surface 13a of the sub lever 13. Thereby, each of the sub lever 13 and the lock release plate 15 is configured to smoothly move up and down (rotate integrally) along the arc.

An extension portion 15 b extending outward in the diameter direction is formed on the upper portion of the lock release plate 15.
Further, a spring hook 15d is provided between the connecting portion 15a and the extending portion 15b of the lock release plate 15, and one end of the spring 17 is hung on the spring hook 15d. The other end of the spring 17 is hung on a spring hook 27a of a hook plate 27 attached to the case 11a. The spring 17 urges the lock release plate 15 to rotate in the clockwise direction, rotates to a position where the extension portion 15b contacts the lock arm 14, and according to the rotation position of the lock arm 14, The extending portion 15b is engaged with the second notch portion 14f, or the corner portion 15c of the extending portion 15b is in sliding contact with the second peripheral edge portion 14c.

When releasing the lock, the engagement by the extended portion 15b to the second notch portion 14f is released by operating the sub lever 13, so that the operation lever 12 can be operated together with the lock arm 14. .
Further, a return plate 15 e formed in a flat plate shape is provided on the disk surface of the lock release plate 15.

  Here, the arrangement position of the line segment connecting the spring hook 15d of the lock release plate 15 and the spring hook 27a of the hook plate 27 of the case 11a, that is, the arrangement position of the spring 17 that is hung on both ends of the spring hook 15d and the spring hook 27a, When the sub-lever 13 and the lock release plate 15 are in the non-operational position where the operation lever 12 cannot be operated from the locking side to the unlocking side before the sub-lever 13 is operated. The sub lever 13 and the lock release plate 15 are urged to the operation impossible position side before the operation. In this state, when the sub lever 13 is slightly operated toward the operable position side where the operation lever 12 can be operated from the locking side to the unlocking side and then released, the sub lever 13 and the lock release plate are released. 15 returns to the unoperable position side before the operation by the urging force of the spring 17.

When the sub-lever 13 is operated to the fully operable position, the arrangement position of the line connecting the spring hook 15d and the spring hook 27a, that is, the arrangement position of the spring 17 passes through the rotation center of the sub-lever 13 and the lock release plate 15. Beyond the position, it is below the center of rotation.
The position where the spring 17 overlaps the center of rotation is the neutral position of the spring 17, and when the spring 17 is disposed at this neutral position, the spring 17 operates the sub lever 13 and the lock release plate 15 on the non-operable position side. The sub-lever 13 and the lock release plate 15 are stopped without rotating unless receiving any external force.
When the spring 17 reaches below the rotation center, the spring 17 biases the sub lever 13 and the lock release plate 15 toward the operable position.
Therefore, when the sub lever 13 is operated to the operable position, the sub lever 13 and the lock release plate 15 are stopped at the operable position side without being returned to the operation disabled position.

  Thus, if the sub lever 12 is operated to the operable position, even if the finger is released from the sub lever 12, the sub lever 12 does not return and the operation lever 12 can be operated. In this state, when the operation lever 12 is operated from the locking side to the unlocking side, the lock arm 14 integrated with the operation lever 12 is rotated to be changed from the locked state to the unlocked state. Is in contact with the return plate 15e during the rotational movement, and the lock release plate 15 and the sub-lever 13 are pushed back from the neutral position of the spring 1 to the non-operational position side (upper side) via the return plate 15e. As a result, the sub lever 13 and the lock release plate 15 are urged by the spring 17 to the operation impossible position side, and rotate together with the operation lever 12 when the operation lever 12 is returned from the unlocked position to the locked position. The lock arm 14 is returned to the non-operable position for maintaining the lock arm 14 in an inoperable state at the locked position.

As shown in FIGS. 3 to 15, the interlocking bar (blocking means) 30 is formed in a long flat plate shape, and is attached to a surface of the vertical frame 1 d facing the vertical rod 2 d so as to be slidable in the vertical direction. . An engagement protrusion 31 is provided at the lower end of the interlocking bar 30 and is engaged with the engagement hole 14 i of the lock arm 14. As a result, when the arm portion 14h moves up and down by the rotation of the lock arm 14, the interlocking bar 30 moves up and down as the engagement protrusion 31 engaged with the engagement hole 14i is pushed up or down. It has become.
A flat plate seat 32 having the same width as the interlocking bar 30 is fixed to the interlocking bar 30 with screws 33 and 33. An extension portion 32 a is formed on the seat 32 so as to protrude in the outdoor direction, and a mounting plate 34 is erected on the extension portion 32 a so as to face the shoji 2. A locking plate (locking portion) 35 is attached to the front end surface of the mounting plate 34.
On the other hand, the side of the shovel 2d of the shoji 2 (the end on the open side opposite to the shaft-side end of the shoji (vertical chisel 2c)) faces the vertical frame 1d (in FIG. 1). (Right direction) The locked pin (locked portion) 2f is attached so as to protrude. When this pin to be locked 2f enters the indoor area (the lock area 36) near the lock plate 35, it is locked to the lock plate 35, that is, the interlock bar 30 prevents the shoji 2 from being opened. It is supposed to be locked.

In the opening device as described above, when the shoji 2 in the open state is closed, the shoji 2 is locked by the lock device 10 as follows.
When the shoji 2 is gradually closed by turning the opening / closing handle 3a, as shown in FIGS. 3 and 4, the vertical rod 2d begins to overlap the vertical frame 1d. At this time, the inner surface of the vertical rod 2d comes into contact with the elastic portion 21c of the detection member 21 of the lock device main body 11 in the initial state. The locked pin 2 f of the vertical rod 2 d approaches the locking plate 35 of the interlocking bar 30. At this time, the tip of the claw 19a of the rotating plate 19 is in sliding contact with the upper surface 21f of the tip 21e of the detection member 21.
When the shoji 2 is further closed, the elastic portion 21c is pushed by the vertical rod 2d, and the detection member 21 moves so as to be pushed into the case 11a (FIG. 5). Due to the movement of the detection member 21, the left side surface of the triangular piece 21d abuts against the right side surface of the claw portion 19a, the rotating plate 19 rotates clockwise, and the lower end portion 19b thereof is the first notch portion of the lock arm 14. 14e, the corner 19c of the lower end 19b is in sliding contact with the first peripheral edge 14b of the lock arm 14.
As shown in FIG. 6, the lock arm 14 disengaged by the rotating plate 19 is rotated clockwise by the biasing force of the spring 18. Thereby, the operation lever 12 also rotates clockwise. When the lock arm 14 is rotated clockwise, the engagement protrusion 31 engaged with the engagement hole 14i is pulled down, and the entire interlocking bar 30 is lowered. As a result, the locked pin 2 f starts to be engaged with the entrance of the locking area 36.

When the shoji 2 is kept closed, the detection member 21 further moves, and when the rotating plate 19 is also pushed by the triangular piece 21d and rotates clockwise, the claw portion 19a rises above the triangular piece 21d. 7, the tip of the claw portion 19 a reaches the apex of the triangular piece 21 d, and the lower end portion 19 b of the rotating plate 19 is separated from the lock arm 14. At this time, the spring 18 is most extended against the biasing force.
Then, as shown in FIG. 8, when the shoji 2 is completely closed, the detection member 21 further moves to the left, and when the claw portion 19a passes over the apex of the triangular piece 21d and comes into sliding contact with the upper surface 21g, the spring 18 Due to the urging force, the rotating plate 19 and the lock arm 14 are rotated counterclockwise and clockwise until the corner portion 19c of the rotating plate 19 comes into sliding contact with the first peripheral edge portion 14b of the lock arm 14, respectively. As a result, the engaging projection 31 moves in the engaging hole 14i from the horizontally long opening 14j to the vertically long opening 14k, while the arm 14h and the interlocking bar 30 are lowered, and the pin 2f to be locked is moved to the locking area 36. Enter further.
The lock arm 14 continues to rotate clockwise by the urging force of the spring 18 and the tip of the operation lever 12 reaches above the lock device body 11 (FIG. 9). Then, the lock release plate 15 in which the extended portion 15b remains in sliding contact with the second peripheral edge portion 14c of the lock arm 14 is rotated in the clockwise direction by the urging force of the spring 17, and the second notch When the engaging portion 14f is engaged, the locking arm 14 stops rotating. The descent of the interlocking bar 30 also stops, the locked pin 2f is completely locked by the interlocking bar 30, and the shoji 2 is locked (locked) and cannot be released (blocked state).
As the lock release plate 15 rotates, the sub-lever 13 rises to a position where the upper edge portion of the concave surface 13a falls into the recessed portion 11f of the side wall 11c.

The shoji 2 is closed as described above, and in the locked opening device, the lock is released and the shoji 2 is opened as follows.
First, as shown in FIG. 10, when the sub-lever 13 is operated to be pushed down, the lock release plate 15 rotates counterclockwise against the biasing force of the spring 17, and the engagement by the lock release plate 15 is released. The lock arm 14 becomes rotatable.
Next, as shown in FIG. 11, when the operation lever 12 is operated and turned counterclockwise while the sub lever 13 is pressed down, both the lock arms 14 are also rotated counterclockwise. As a result, the engaging protrusion 31 of the interlocking bar 30 is pushed up while moving in the engaging hole 14i from the vertically long opening 14k to the horizontally long opening 14j, the interlocking bar 30 starts to rise, and the vertical bar 2d is engaged. The stop pin 2 f moves relatively below the locking area 36.
By further lowering the operation lever 12, the lock arm 14 is rotated counterclockwise, the interlocking bar 30 is raised, the locked pin 2f is released from the locking area 36, the lock is released, and the shoji 2 is It can be opened (blocking release state). If the opening / closing mechanism 3 is not operated at this time, the shoji 2 is not opened.

10 to 12, the corner 19c of the rotating plate 19 is in sliding contact with the first peripheral edge 14b of the lock arm 14, but when reaching the end of the first peripheral edge 14b, it is shown in FIG. Thus, the rotating plate 19 rotates counterclockwise while the lower end portion 19b engages with the first notch portion 14e of the lock arm 14 by the biasing force of the spring 18. Thereby, the lock arm 14 and the operation lever 12 cannot be rotated.
When the opening / closing handle 3a is operated, as shown in FIG. 14, the shoji 2 starts to open, and when the vertical rod 2d moves outward, the detection member 21 pushed by the vertical rod 2d is moved by the biasing force of the spring 22 to the case 11a. It is pushed out. At this time, the tip of the claw portion 19a of the rotating plate 19 comes into sliding contact with the upper surface 21g of the triangular piece 21d of the detection member 21, and eventually reaches the apex of the triangular piece 21d. Then, when the claw portion 19a climbs over the apex of the triangular piece 21d, the detection member 21 is slightly rotated clockwise by the urging force of the spring 22 as shown in FIG. 15, and the claw portion 19a is placed on the upper surface 21f of the tip portion 21e. It will be in the state of sliding contact.

As described above, in the opening device of the present embodiment, the lock device 10 is provided, and the lock device 10 detects that the shoji 2 is almost closed by being pushed by the downspout 2d. 21, the interlocking bar 30 that prevents the opening of the shoji 2, the lock arm 14 that drives the interlocking bar 30 so as to prevent the opening of the shoji 2, and the detection member 21 detect that the shoji 2 is almost closed. Then, since the rotation plate 19 is provided to transmit it to the lock arm 14, when the shoji 2 is closed, it is detected by the detecting member 21, and this is transmitted from the rotation plate 19 to the lock arm 14, and the lock arm 14, the interlocking bar 30 is driven to prevent the shoji 2 from being opened. Therefore, the movement of the shoji 2 is detected and automatically locked in a series of operations until the shoji 2 is closed, and the opening device is excellent in crime prevention.
Moreover, since the vertical rod 2d of the shoji 2 is closed with respect to the vertical frame 1d of the frame 1, the wind resistance is also enhanced.

In the present embodiment, each member is configured to be rotated by a predetermined angle using the biasing force of the spring and locked. However, the present invention is not limited to this, and other mechanical elements may be combined. The members constituting the lock device may be electrically driven and controlled.
In this case, for example, as a detecting means for detecting that the shoji is closed, a mechanical sensor that detects that the shoji is closed by touching the shoji, or an optical sensor that detects that the shoji is closed by light. Etc. can be used. The drive means can use a drive source such as various actuators by electric or air, but preferably has a structure capable of maintaining the lock in the event of a power failure and can be manually unlocked. A single reciprocating operation (operation by turning on and off the power supply) may result in a locked state, and unlocking may be manually performed as in this example. The transmission means is a signal line or a control circuit provided between the sensor and the actuator (drive circuit).
Moreover, you may provide a locking device not in the vertical frame 1d (vertical frame 1c) of the frame 1, but in the upper frame 1a and the lower frame 1b.
Furthermore, although the opening device having the operator type opening / closing mechanism is described above, the locking device of the present invention may be combined with the opening device having the cam latch type opening / closing mechanism. In the case of the cam latch type, the shoji cannot be opened by closing the opening / closing handle, but it is double-locked by the locking device of the present invention, and crime prevention is further improved.
In addition, in the present embodiment, the case where the present invention is applied to a casement that opens by rotating around a vertical axis is described as an example, but the present invention is configured by a frame and a shoji, and the shoji is left and right or up and down. You may apply to the window etc. which move or a shoji sticks out.
