And durability can be improved.

The joinery of the present invention includes a shoji that is slidably opened and closed, and a first summoning section provided on the shoji and a second summon provided on the indoor side or the outdoor side of the shoji. Is a fitting that can be locked by a locking device in a state in which it is overlapped in the prospective direction, and the locking device is an indoor side summing unit located on the indoor side among the first and second summing units. A crescent lock provided on the outdoor side, and a lock receptacle provided on the outdoor side summing portion located on the outdoor side so as to be able to engage with the crescent lock, wherein the crescent lock includes the indoor side summing portion. A pedestal that is fixed to the pedestal, a sickle lock that is supported by the pedestal and that is pivotable between a locked position that engages with the lock receiver and an unlocked position that does not engage, and is connected to the sickle lock. Operation member for rotating the sickle lock and the operation unit A detecting member for detecting the closed state and the non-closed state of the shoji in conjunction with the operation, and a solution for restricting the rotation of the sickle lock and the operating member in the unlocking direction when the sickle lock is in the locked position. The detection member includes a detection unit biased in a direction protruding from the pedestal toward the outdoor side, and a restriction that restricts rotation of the sickle lock and the operation member. The detection member is pivotally supported by the pedestal, or is supported by the pedestal and is slidable indoors and outdoors, and the unlocking restriction member is the pedestal And is urged toward the restriction position, and is movably provided toward the non-restriction position in conjunction with the rotation of the sickle lock and the operation member in the locking direction. When the operating member is locked with As the unlocking / regulating member moves toward the non-regulating position, the detection part of the detecting member protrudes by a predetermined amount toward the outdoor side, so that the part that rotates together with the sickle lock and the operation member When the rotation operation is restricted by the restriction part of the detection member and the operation member is operated in the closed state of the shoji, the detection part of the detection member comes into contact with the lock rest or the outdoor summing part. Thus, the detection unit does not protrude to a predetermined amount, and the locking operation is continued without the rotation operation of the portion rotating together with the sickle lock and the operation member being regulated by the regulation unit of the detection member. Is rotated to the locking position and engaged with the lock receiver, and when the sickle lock is rotated to the locking position, the unlocking restriction member moves to the restriction position side, and the unlocking restriction member The unlocking operation of the sickle lock and the operation member is restricted, and The sickle lock and the operation member may be configured to be unlockable by moving the unlocking restriction member to a non-restricted position.

  Furthermore, in the joinery of the present invention, it is preferable that the operation member is provided with a detection unit protruding means for protruding the detection unit of the detection member in a state where the sickle lock is in the unlocked position.

  According to such a configuration, the lock receiver can be engaged by causing the detection portion of the detection member to protrude using the detection portion protrusion means before locking the operation member to rotate the sickle lock. Whether or not it is in the position is detected before the locking operation, and it can be more clearly discriminated that it is in an empty state. At this time, if the detection unit protruded by the detection unit protrusion means protrudes by a predetermined amount, if the operation member is made inoperable, the user can more clearly determine that it is in an idle state. Thus, it is possible to prevent the locking operation with an excessive force, and to further improve the operability and durability.

  In the joinery of the present invention, it is preferable that the crescent lock is provided with a detection portion protrusion restricting means that does not protrude the detection portion of the detection member to a predetermined amount in a state where the sickle lock is in the locked position.

  According to such a configuration, even if the sickle lock is turned to the locking position without being engaged with the lock receiver, the detection portion protrusion restricting means restricts the protrusion of the detection portion. The unlocking restriction member can move to the non-restriction position, whereby the sickle lock and the operation member can be unlocked, and the abnormal locking state can be released. In other words, when a locking operation is performed in a state where the child's mischief or unexpectedly gets caught, and the protrusion of the detection unit is restricted, the double lock by the unlocking restriction member is simultaneously applied. For this reason, the unlocking restricting member must be moved to the non-regulating position to release the double lock, and then the operating member must be unlocked. However, if the detection part of the detection member protrudes as the unlocking restriction member moves to the non-restriction position, the detection part protrudes by a predetermined amount because the lock receiver is not in the contact position, and the unlocking restriction member The movement of the lock is restricted, and the double lock cannot be removed, and the abnormal locked state may not be released. Therefore, by controlling the protrusion of the detection part in the state where the sickle lock is in the locked position by the detection part protrusion restricting means, the unlocking restriction member can move to the non-restricted position (the double lock is released). Since the sickle lock and the operation member can be unlocked, it can be released even if the abnormal locking state as described above occurs.

  Hereinafter, each embodiment of the present invention will be described with reference to the drawings.

The sliding window 1 is composed of a crescent lock 11 fixed to the inner summon basket 2 of the indoor shoji and a lock device 10 composed of a lock holder 12 fixed to the outer summon 3 of the outdoor shoji. It is to be locked by.

  The crescent lock 11 is rotatably provided between a pedestal 13 fixed to the inner summit bowl 2 and a locked position that is supported by the pedestal 13 and engages the lock receiver 12 and an unlocked position that does not engage. From the locking position of the sickle lock 14 supported by the pedestal 13 and a knob 15 as an operation member for rotating the sickle lock 14 and connected to the sickle lock 14. It has a double lock member 16 as an unlocking restricting member for restricting rotation to the unlocking position. Inside the pedestal 13, a back metal 17 fixed to the rotation shaft 141 of the sickle lock 14 and a sickle lock 14 and a knob 15 connected to the back metal 17 are attached to either the locked position or the unlocked position. A coil spring 18 to be energized and a trigger 19 as a detection member for detecting the closed state and the non-closed state of the shoji are interlocked with the rotation of the sickle lock 14.

  The double lock member 16 includes an unlocking operation portion 161 exposed from the pedestal 13 to the indoor side, a slide portion 162 connected to the unlocking operation portion 161 and provided inside the pedestal 13, and a lower end portion of the slide portion 162. And a coil spring 163 that is connected to the base 13 and biases the slide portion 162 downward. As shown in FIG. 3, the slide portion 162 has an inclined surface 164 that comes into contact with the first bent piece 171 of the back metal 17, and a sickle lock 14 that comes into contact with the second bent piece 172 of the back metal 17 in the locked position. Are engaged with a restricting surface portion 165 for restricting rotation in the unlocking direction, an urging surface portion 166 for urging a locking portion 192 (described later) of the trigger 19 downward, and a locking portion 192 of the trigger 19 when empty. And a locked portion 167 to be stopped. Such a double lock member 16 is configured such that the first bent piece 171 of the back metal 17 abuts against the inclined surface 164 and pushes up as the sickle lock 14 rotates from the unlocked position in the locking direction. 162 and the unlocking operation portion 161 slide upward against the urging force of the coil spring 163.

  The trigger 19 is pivotally supported on the pedestal 13, and is provided on one side (upper side) with the pivotal support position interposed therebetween and can be projected from the pedestal 13, and provided on the other side. The double lock member 16 is formed with a locking portion (regulating portion) 192 capable of locking the locked portion 167 of the double lock member 16. The trigger 19 is urged in a direction in which the detection unit 191 protrudes from the pedestal 13 (right rotation direction in the figure) by a torsion coil spring 193 provided between the trigger 19 and the double lock member. The engaging portion 192 is urged downward by the urging force of the coil spring 163 through the urging surface portion 166 of the 16, so that the pedestal 13 is immersed. Such a trigger 19 is detected by the sliding portion 162 of the double lock member 16 sliding upward, so that the locking portion 192 moves inward along the urging surface portion 166 and the trigger 19 rotates. The part 191 protrudes to the outdoor side.

  Next, the operation of the lock device 10 will be described.

  Here, the locking operation in the locking device 10 is a state in which the sickle lock 14 and the knob 15 of the crescent lock 11 are in the unlocked position and the sickle lock 14 is not engaged with the lock receiver 12 as shown in FIG. 2, the knob 15 is operated upward in the room (left side in the figure) to rotate the sickle lock 14 in the locking direction (toward the locking position).

  Further, as shown in FIG. 4, the unlocking operation in the locking device 10 means that the sickle lock 14 and the knob 15 of the crescent lock 11 are in the locked position, and the sickle lock 14 is engaged with the lock receiver 12 to 15 is an operation to rotate the sickle lock 14 in the unlocking direction (toward the unlocking position) by operating 15 downward in the room.

  First, as shown in FIGS. 1 and 2, in a state where the lock receiver 12 is in an engageable position, that is, in a closed state where the indoor and outdoor shoji is closed, the knob 15 is operated to lock and the sickle lock 14 is rotated. In this case, the first bent piece 171 of the back metal 17 pushes up the inclined surface 164 of the double lock member 16, and the unlocking operation unit 161 and the slide unit 162 slide upward. And the latching | locking part 192 of the trigger 19 moves to the indoor side along the urging | biasing surface part 166 of the slide part 162, the trigger 19 rotates, and the detection part 191 protrudes to the outdoor side. When the protruding detection portion 191 abuts against the lock receiver 12, the movement of the locking portion 192 stops at the outdoor position relative to the regulating surface portion 165 of the slide portion 162, as shown in FIG. The locked portion 167 of the slide portion 162 is not locked to 192. Accordingly, the unlocking operation portion 161 and the slide portion 162 of the double lock member 16 continue to slide upward, and the rotation operation of the sickle lock 14 is continued and the sickle lock 14 is engaged with the lock receiver 12.

  Next, as shown in FIG. 4, when the operation of the knob 15 is continued and the sickle lock 14 is rotated to the locked position, the second bent piece 172 of the back metal 17 is restricted by the double lock member 16. The force that pushes up the slide portion 162 by rotating from the surface portion 165 to the outdoor side does not act. As a result, the slide part 162 and the unlocking operation part 161 urged by the coil spring 163 slide downward, and the locking part 192 pressed by the urging surface part 166 of the slide part 162 is pushed out to the outdoor side. The trigger 19 rotates in a direction in which the portion 191 is immersed in the pedestal 13. Then, the second bent piece 172 of the back metal 17 is brought into contact with the restriction surface part 165 of the slide part 162 that has been slid to the lower restriction position, whereby the rotation of the back metal 17 in the unlocking direction is restricted. 14 and knob 15 cannot be unlocked, that is, a double lock is applied. Further, in this locked state, the first bent piece 171 of the back metal 17 is urged downward by the coil spring 18, so that the back metal 17, the sickle lock 14 and the knob 15 maintain the locked position. .

  In the locking device 10 in the locked state as described above, the unlocking operation portion 161 of the double lock member 16 is slid upward and moved to the non-regulated position, whereby the restriction surface portion 165 of the slide portion 162 is used. The restriction of the second bent piece 172 of the back metal 17 is released, the back metal 17 can be rotated in the unlocking direction, and the unlocking operation of the sickle lock 14 and the knob 15 can be performed. When the sickle lock 14 and the knob 15 are rotated to the unlocked position and unlocked, the first bent piece 171 of the back metal 17 is urged downward by the coil spring 18, so that the back metal 17, the sickle lock 14 and the knob 15 maintain the unlocking position.

  On the other hand, as shown in FIG. 5, the sickle lock 14 was rotated by operating the knob 15 in a state where the lock receiver 12 was not in the engageable position, that is, in a non-closed state where the indoor and outdoor shoji was not closed. In this case, since the detection unit 191 of the trigger 19 does not contact the lock receiver 12, the detection unit 191 protrudes to the outside by a predetermined amount, that is, the trigger 19 rotates to a position where it contacts the pedestal 13. When the detection unit 191 protrudes by a predetermined amount in this manner, the locking portion 192 of the trigger 19 moves to the indoor side position with respect to the regulation surface portion 165 of the slide portion 162, and the locked portion 192 is locked to the locking portion 192. The part 167 is locked. Therefore, the sliding of the double lock member 16 to the upper side of the slide portion 162 is restricted, and the sickle lock 14 cannot be further rotated, so that the user can determine that it is in an empty state. It has become. When the locking operation is stopped, that is, when the finger or hand is released from the knob 15, the back metal 17 and the slide portion 162 are moved downward by the biasing force of the coil springs 18 and 163, and the sickle lock 14 and the knob 15 are moved in the unlocking direction. And is automatically returned to the unlocked state.

According to this embodiment, there are the following effects.
(1) That is, even if the locking operation is performed in a non-closed state in which the shoji is not closed (the lock receiver 12 is not in the engageable position), the locking portion 192 of the trigger 19 protruding by a predetermined amount Since the locked portion 167 of the heavy lock member 16 is locked and the locking operation of the sickle lock 14 and the knob 15 is restricted, it is possible to prevent emptying. If the operation is stopped when it is determined that the locking operation is impossible, the sickle lock 14 and the knob 15 are automatically returned to the unlocked state by the urging force of the coil springs 18, 163, and may be in an empty state. It can be easily distinguished from the user.
(2) On the other hand, in the state where the shoji is closed and the lock receiver 12 is in the engageable position, the locking operation can be continued and the coil spring 163 is biased in this locked state. By restricting the second bent piece 172 of the back metal 17 with the restricting surface portion 165 of the slide portion 162, the unlocking operation of the sickle lock 14 and the knob 15 can be restricted, and a double lock can be automatically applied. it can. And since the double lock is removed and the sickle lock 14 and the knob 15 can be rotated simply by operating the unlocking operation portion 161 of the double lock member 16 provided on the indoor side of the pedestal 13, the unlocking can be easily performed. Operations can be performed.
(3) Furthermore, since the double lock member 16 and the trigger 19 are provided on the pedestal 13, it is less likely to be restricted by the member size compared to the case where these members are provided on the sickle lock 14 side, and the member strength Can improve durability. Then, the locking portion 192 of the trigger 19, the locked portion 167 of the double lock member 16, and the first bent piece 171 of the back metal 17 restrict the rotation of the sickle lock 14 and the knob 15 to prevent emptying. By doing so, it is possible to reduce the force acting on each member by dispersing the operating force acting at the time of emptying, and to further improve the durability. Further, at the time of locking, the second bent piece 172 of the back metal 17 and the restricting surface portion 165 of the double lock member 16 are used to restrict the rotation of the sickle lock 14 and the knob 15 so that the double lock is applied. The operating force that acts when the knob 15 is unlocked while the lock is applied can be dispersed.
