By the way, such a sliding door can be locked only in the fully closed state, and therefore, when trying to ventilate it in the half-opened state in hot weather such as summer, it will remain in the unlocked state and it will be extremely dangerous for crime prevention. Be wary and problematic.

[Means for Solving the Problems] The present invention has been made in view of the above circumstances and was devised for the purpose of providing a sliding door locking device capable of eliminating these drawbacks. A locking device for a sliding door that moves and opens and closes to a door, the locking device including a communication part formed to communicate in the left-right direction with a frame member facing the left-right direction of an outdoor door body, and the communication part. A movable member which is guided by the movable member to be movable in the left-right direction, a plurality of first notches formed on the indoor side surface of the frame member, and a locking posture and a frame protruding from the first notches. A plurality of stoppers provided on the movable member so as to be freely rockable and deformable in an immersing unlocking posture, an ammunition for urging the stoppers toward the locking posture side, and a door end side end of the frame member. A second notch formed in the indoor side surface located in the section, and integrally provided in the movable member. ,
Also, an operating tool that is exposed to the outside from the second notch and that moves the movable member between the lockable position where the stopper corresponds to the first notch and the lockable position that is displaced from the first notch. Further, the end of the first notch on the non-lockable position side is brought into contact with the stopper in the locking posture in accordance with the operation of the movable member to the non-lockable position side by the operation tool, and the stopper is attached. It is characterized by being configured as an automatic transformation unit that automatically transforms to the unlocked posture.

According to the present invention, the sliding door can be locked and unlocked by one-touch operation of the operation tool.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numerals 1 and 1a denote sliding door type door bodies that open and close by moving to the left and right, and the door bodies 1 and 1a are both horizontal rails 2 and 3 and vertical rails on the left and right. The outer side door body 1 is constructed by forming a frame around four circumferences by 4 and 5 and inserting the glass plate 6 therein.
The lower frame 3 has a lock position in which the present invention is implemented.

That is, the lower frame 3 of the outdoor side door body 1 is formed with a communication portion S opened in the left-right communication direction, and the operating rod (corresponding to the movable member of the present invention is guided by the communication portion S. Do)
7 is attached so as to be movable in the left-right direction. Further, on the indoor side surface of the lower frame 3, a plurality of first notches 3b are provided at one end side at predetermined intervals and a second notch 3a is provided at the other end side. . Then, the operating rod 7
The base end portions of the plurality of stoppers 8 are swingably supported by the respective support shafts 9 corresponding to the plurality of first cutouts 3b, and the base end portions of these stoppers 8 are supported. A twist ammunition machine 10 is installed at the tip of the stopper 8, and the tip of the stopper 8 has no first 3b.
It is always urged toward the indoor side over the distance, and the stopper 8 is set so as to be able to appear and disappear from the first notch 3b. Further, the operating rod 7 is provided with an operating knob (corresponding to an operating tool of the present invention) 7a in a state of protruding from the second notch 3a toward the indoor side.

Then, when the stopper 8 is in the lockable position opposite to the first notch 3b, the stopper 8 has a locking posture in which the tip of the stopper 8 projects from the first notch 3b, and in this state, the operation knob 7a is moved to the arrow A direction. By sliding the stopper 8 in the direction, the stopper 8 is located in the lockable position where the stopper 8 sinks into the lower frame 3, but at this time, the edge of the first notch 3b on the lockable position side is automatic. It is connected to the transformation part C, and it is Stopper 8
Is set to abut on the automatic transformation part C as it moves to the unlockable position, swing while resisting the torsion bullet machine 10, and automatically transform to the unlocked posture. . On the other hand, if the operation knob 7a is slid in the direction opposite to the arrow A from the unlocked state, the stopper 8 automatically protrudes from the first notch 3b toward the inside of the room by the biasing force of the twisting ammunition 10, and the locked posture. Next to
The indoor side door body 1a is abutted and locked to the edge portion to regulate the further opening operation of the door body 1a.

Further, the stopper 8 is pushed by the lower frame 3 while being located at the lockable position, which is the position facing the first cutout 3b, with respect to the indoor side door body 1a opened beyond this, and the indoor side door 1a is pressed. It is configured to allow the closing operation of the body 1a. Incidentally, in the embodiment, the attachment position of the stopper 8 is set to a plurality of half-open positions including the fully closed position of the door body 1.

In the embodiment of the present invention configured as described above, when the door 7 is normally opened and closed, the knob 7a is slid in the direction of the arrow A so that the stopper 8 is housed in the lower frame 3 and the indoor side door is opened. The body 1a can perform normal opening and closing operations without any problem.

Then, when it is desired to keep the door partially open on a hot day such as summer, the operation knob 7a is operated in the direction opposite to the arrow A with the indoor side door 1a set to the desired half-open position, and the stopper 8 is completely cut. It suffices if the indoor side door body 1a is made to further open in this state, and the indoor side door body 1a contacts the projecting stopper 8 to prevent further opening. Will be. Moreover, the indoor side door body 1a that is locked in the half-opened state can be freely allowed to move in the closing direction up to the fully closed position, and the crime prevention can be greatly improved. Further, in this case, since it is locked by the stopper 8 even in the fully closed state, there is an advantage that it can contribute to eliminating forgetting to lock.

Moreover, when unlocking the stopper 8 in the locked posture, the stopper 8 is moved to the lock-disabled position by operating the operation knob 7a. Since it comes into the unlocked posture automatically by contacting the side edge portion C, as in the conventional case, the stopper is operated in the unlocked posture and then the two-step operation is performed such that the stopper is moved in the left-right direction. The lock operation can be performed by a one-touch operation of sliding the operation knob 7a in the direction of arrow A. As a result, unlocking and locking operations can be performed very easily, and operability is improved.

Furthermore, since the operating rod 7 is provided with a plurality of stoppers 8 and all the stoppers 8 are collectively displaced between the lockable position and the lockable position by one operation of the operation knob 7a. This is convenient because it eliminates the need to individually operate each stopper and improves operability.

By the way, in this embodiment, the operation knob 7a is set to cover the second notch 3a when it is operated in the direction opposite to the arrow A as described above, so that the operation knob 7a is blinded. When the stopper 8 is set in an unlockable position where it is recessed in the frame so as to be accommodated in the concave groove 7b formed in the above, the convex portion 7c of the operating rod 7 has the first notch 3b.
It is supposed that the blindfolds are closed by covering the first and second cutouts 3a and 3b, so that the first and second cutouts 3a and 3b are opened. It is convenient because it surely avoids it.

The present invention is not limited to the above-mentioned embodiment, and the number, intervals, positions, etc. of stoppers can be appropriately selected as necessary, and those having a center frame in the door body, It goes without saying that it may be attached to the center frame. Further, in the case of locking in the half-opened state, it is preferable to lock the outdoor side door body to the building side in order to prevent both door bodies 1 and 1a from moving at the same time.

[Advantages] In short, since the present invention is configured as described above, when it is desired to partially open the door body, the operation is performed with the indoor door body set to a desired half-open position corresponding to the stopper. It suffices to operate the tool to set the movable member to the lockable position, whereby the stopper at the corresponding position automatically projects from the first lack by receiving the urging force of the ammunition to establish the locked posture. As a result, the indoor side door is set in a state in which opening beyond the half open position is restricted.

On the other hand, in order to put the stopper in the locked position into the unlocked position, the movable member may be set to the non-lockable position by the operation of the operation tool, whereby the stopper in the locked position is automatically changed. The state in which the stopper is in the unlocked position as in the past, with the first part of the figure being in contact with the edge on the non-lockable position side to automatically enter the unlocked position and stored in the frame. Therefore, it is not necessary to move the operation tool in the left-right direction, and only one-touch operation of the operation tool to the non-lockable position side is required, and the operability can be improved.

Moreover, since each stopper is provided on one movable member, all the stoppers can be collectively displaced to the lockable position and the lockable position by operating the operation tool, and the displacement operation of each stopper can be performed. Since it is not necessary, the operability can be improved in this respect as well.
