[Prior art]

 As a complementary means for locking the sliding door, a wedge type which is fitted into a groove on the inner surface of the sliding door has been often used. The sliding door is composed of, for example, one inner door and one outer door. When the sliding door is closed, the outer door is pressed against the fixed frame on the house side in the inner door groove inside the outer door. In addition to the locking means consisting of a rotary lever (locking piece) and a hook (fixing piece) installed on the sliding door, the opening (movement) of the outer door can be locked by installing . In addition, since the inner door is also installed in the groove for the inner door, it cannot be moved to the side of the sliding door lock supplementary device. Therefore, when the sliding door is one inner door and one outer door, the opening of both the inner door and the outer door can be locked only by installing the sliding door complementary device at one place.

[0005] However, locking by such a conventional sliding door locking complementing means must be performed separately from the original locking for each sliding door, and it is time-consuming, and it is necessary to confirm each sliding door one by one. Therefore, the equipment is simple, but the actual use is troublesome, especially when there are multiple sliding doors and a wide area.

[Embodiment of the invention]

 Embodiments of the present invention will be described with reference to the drawings and by the following embodiments.

FIG. 1 is a schematic front view of a sliding door locking and complementing device according to one embodiment installed on a sliding door as viewed from the indoor side, and FIG. 2 is a rotation lock piece and a stopper of the sliding door locking and complementary device according to one embodiment. FIG. 3 is a schematic explanatory view showing the positional relationship and orientation of a piece and an abnormality detection switch in a sliding door, and FIG. FIG. 4 is a partially cutaway cross-sectional explanatory view as viewed from the left side of FIG. 1 to the right. FIG. 4 is a view of the unlocked state of the sliding door locking complementary device of one embodiment viewed from the left side of FIG. FIG. 5 is a schematic cross-sectional view showing the configuration of the reset switch, and FIG. 6 is a schematic front view of a centralized control board holding operation pins of the reset switch.

As shown in FIG. 1, the sliding door locking complementary device according to the present embodiment is applied to a sliding door including one outer door 1 and one inner door 2.

As shown in FIG. 1 and FIG. 3, the sliding door locking supplementary device of this embodiment is basically a rotary type locking device located on the inner door 2 side of locking means installed on a normal sliding door. In conjunction with the locking operation by the locking piece 4 of the above, the locking by the new rotation locking piece 3 is complementarily possible. That is, one end of the rotating lock piece 3 installed on the center upper surface of the frame of the inner door 2 is pushed up via the cooperation means 5 by the locking operation of the rotary locking piece 4, and the rotating lock piece is The other end of the sliding door 3 enters a position where it is clipped by the stopper piece 6 fixed to the inner surface of the upper frame of the outer door 1 and the side end of the inner door 2, and the sliding door is locked.

As shown in FIGS. 2 to 4, the rotation lock piece 3 is rotated in a direction perpendicular to the surface of the sliding door and around a center thereof by a shaft 3 a to a cylindrical cover 7 for covering the same. Attach freely. Both ends of the rotation lock piece 3 project from corresponding portions of the cylindrical cover 7, that is, openings 7a and 7b formed on the window side and the opposite side. Needless to say, the openings 7a and 7b are configured to have dimensions that allow the rotation of the rotation lock piece 3 within a required range.

The stopper piece 6 is fixed to the inner surface of the upper frame of the outer door 1 as described above and shown in FIGS. The stopper piece 6 has a length corresponding to the width of the upper frame of the outer door 1. Such a length is set such that when the outer door 1 is opened, the outer door 1 is immediately moved so as to overlap the inner door 2, and for some reason, the turning lock piece 3 is moved. The purpose is to prevent the inconvenience that the outer door 1 cannot be moved in the closing direction by rotating in the locking direction and having its tip entering the opposite side of the stopper piece 6.

As shown in FIG. 3, a mounting hole 3 b arranged on the indoor side from the shaft 3 a of the rotation lock piece 3 is connected to the upper part of the lock piece 4 via a linking means 5. As shown in FIGS. 3 and 4, the linking means 5 comprises a lower structure 5a and an upper structure 5b. The upper end of the upper structure 5b is connected to the mounting hole 3b of the rotation lock piece 3, and The lower end of the lower structure 5 a is fixed to the upper part of the locking piece 4.

As shown in FIGS. 3 and 4, the lower end of the upper structure 5b is formed as a coil spring 5b1, and the upper end of the lower structure 5a is similarly formed as a coil spring 5a1. Fix the disk material 5a2. Also, the range in which the coil springs 5b1, 5a1 and the disk material 5a2 of the upper structure 5b and the lower structure 5a move up and down is covered with a guide cylinder 5c that can smoothly move them up and down. At the lower end of the cylinder 5c, a lid having a guide hole 5c1 opened in the center is fixedly provided, and the lower rod-shaped portion of the lower structure 5a extends downward through the guide hole 5c1. I have.

As described above, the locking piece 4 is previously installed on the sliding door. As shown in FIG. 3, the locking piece 4 is provided around the shaft 4 a in the middle of the frame of the inner door 2. When it is pivoted upward (locking operation), that is, as shown by arrow 8 in the figure, it is disposed at a corresponding position on the center side of the frame of the outer door 1. Is fixed to the fixed piece 9, and when it is rotated downward (operation in the opposite direction to the above-mentioned rotation, unlocking operation), the lock with the fixed piece 9 is released. It is.

Accordingly, in a locking operation for rotating the locking piece 4 upward, the lower structure 5a of the linking means 5 rises in conjunction with this, and the disk member 5a2 disposed on the upper end of the coil spring 5a1 moves upward. It comes into contact with the lower end of the coil spring 5b1 of the configuration 5b and pushes it up. Accordingly, the upper end of the upper structure 5b pushes up the inside end of the rotation lock piece 3 so that the outside end of the rotation lock piece 3 is located between the stopper piece 6 and the central side surface of the interior door 2, as shown in FIG. Into a locked state with the stopper piece 6, that is, a locked state.

On the other hand, at the time of the unlocking operation for rotating the locking piece 4 downward, even if the lower structure 5a of the linking means 5 is lowered, the lower structure 5a is separated from the upper structure 5b. The pivot lock piece 3 does not descend, so that the rotation lock piece 3 maintains the locked state. Thus, even if a person who tries to open the sliding door on which the door is installed and breaks the glass or the like of the outer door 1 or the inner door 2 to unlock the locking piece 4 of the existing locking means, the rotation lock is not required. The locked state by the piece 3 is maintained, and plays the role of locking complement.

In the operation described above, the cylinder 5c moves up and down smoothly without tilting of the coil spring 5a1, the disk member 5a2 of the lower structure 5a and the coil spring 5b1 of the upper structure 5b of the cooperation means 5 during the above operation. The disk member 5a2 effectively acts to prevent the two coil springs 5b1 and 5a1 from being unnecessarily entangled. The guide hole 5c1 opened at the lower end of the cylinder 5c acts to prevent the coil spring 5a1 of the lower structure 5a from tilting in the cylinder 5c when the coil spring 5a1 moves up and down.

The coil springs 5 a 1 and 5 b 1 of the lower structure 5 a and the upper structure 5 b of the linking means 5 are provided with a stroke of the upper structure 5 b and a locking piece 4 necessary for rotating the rotation lock piece 3 in the locking direction. This serves to adjust the difference in the stroke of the lower structure 5a generated by the locking operation of the above. In other words, due to the dimensional restrictions of the locking piece 4 and the rotation locking piece 3, the locking operation of the rotation locking piece 3 is smaller than the moving amount Δl of the lower structure 5 a accompanying the locking operation of the locking piece 4. The upper and lower displacements Δd required by the coil are small, and therefore, the coil springs 5a1 and 5b1 are formed at the upper end of the lower structure 5a and the lower end of the upper structure 5b, respectively, to absorb the deviation between the moving amount Δl and the displacement Δd by their spring action. Then, the buckling of each bar is prevented. In addition, the material which satisfies moderate rigidity and flexibility is selected for the material of the lower structure 5a and the upper structure 5b.

As shown in FIGS. 3 and 4, a lower end of a push spring 10 is fixed to the cylindrical cover 7. The push spring 10 is slightly inclined upward toward the interior of the room, and is bent in an arc shape toward the exterior of the room near the upper end. As shown in FIG. 3, the rotation lock piece 3 is in the locked state. In this embodiment, the lower half of the indoor side end is supported by the tip of the push spring 10 and acts to maintain the locked state. In a state where the rotation lock piece 3 is unlocked, as shown in FIG. 4, the distal end of the push spring 10 restrains the upper part of the indoor side end of the rotation lock piece 3 and the locking direction. Acts to prevent the rotation of.

However, the action of the pressing spring 10 needs to be gentle, and if a strong external force in a predetermined direction is applied to the rotation lock piece 3, the locking state is released against the pressing spring 10. Or in the locking direction.

As shown in FIGS. 3 and 4, a locking hole 3 c is opened at the indoor side end of the rotation lock piece 3. The lock hole 3c is suspended by a pull cord for unlocking the rotation lock piece 3 and pulled down if necessary, or by using a release operation rod having a lock piece at the tip. The locking piece is locked in the locking hole 3c, and the indoor side end of the rotation locking piece 3 is pulled down to be used for unlocking operation.

As shown in FIGS. 1 to 4, an abnormality detection switch 11 is installed near the rotation lock piece 3 on the fixed frame above the sliding door. The abnormality detection switch 11 is constituted by a micro switch, and is positioned so that the roll lever 11a can be moved up and down by the rotation up and down operation of the indoor side end of the rotation lock piece 3. That is, as shown in FIG. 3, the abnormality detection switch 11 is positioned so that the roll lever 11a is in the raised state when the rotation lock piece 3 is locked, and the contact is opened in this state. Set as follows. In this way, as shown in FIG. 4, when the rotation lock piece 3 is unlocked, the roll lever 11a is lowered, and the contact is closed in this state.

As shown in FIG. 1, the abnormality detection switch 11 is inserted in the middle of a power supply circuit 13 for driving a separately installed buzzer 12. When the rotation lock piece 3 is unlocked, the contact point is closed, the power supply circuit 13 is closed, and the buzzer 12 operates so as to emit an alarm sound.

As shown in FIG. 1, the power supply circuit 13 has a power supply battery 18 and a reset switch 14 inserted in series with the abnormality detection switch 11, and is connected to the abnormality detection switch 11 and the reset switch 14. The buzzer 12 emits an alarm when both are closed. As shown in FIG. 1, the circuits of the abnormality detection switch 11 and the reset switch 14 are arranged in parallel with those to be installed on other sliding doors.

The reset switch 14 is arranged close to the sliding door of the subject, and its switch mechanism is constituted by a micro switch as shown in FIG. As shown in the figure, the reset switch 14 is disposed along a longitudinal direction in a cylindrical case 15 arranged in an upright state, and the swing direction of the roll lever 14a is set in front and rear of the cylindrical case 15. Direction. Pin holes 15a and 15b for inserting operation pins 16 for switch operation are opened in the front and rear portions of the cylindrical case 15, and as shown in FIG. When the pin is inserted into the pin holes 15a and 15b from the front side of the cylindrical case 15, the roll lever 14a is pushed rearward, and the contact of the reset switch 14 is set to open. Therefore, if the operation pin 16 is inserted into the pin holes 15a and 15b as shown in the figure, the buzzer 12 emits an alarm even if the rotation lock piece 3 is unlocked. Never.

The operation pin 16 has a number written on its head, and the number indicates a sliding door number for specifying a sliding door provided with a sliding door locking complementary device in a building. .

The operation pin 16 is in a state where the sliding door locking complementary device is operated, that is, the rotation lock piece 3 is in a locked state and the abnormality detection switch 11 is in an off state. The operation pins 16 are to be removed from the pin holes 15a and 15b of the cylindrical case 15, but in this case, as shown in FIG. The operation pin 16 is in a state where the operation of the sliding door locking complementary device is stopped, that is, when the rotation lock piece 3 is unlocked and the abnormality detection switch 11 is allowed to be turned on. This should be inserted into the pin holes 15a and 15b of the cylindrical case 15 in advance, and the reset switch 14 should be turned off.

The centralized control plate 17 is a plate-like member in which a sliding door number is indicated by a circled number in an upper row, and holding holes 17a for holding operation pins 16 of numbers corresponding to a lower row are arranged. The centralized management board 17 determines whether or not the operating pins 16, 16... Of the sliding door numbers corresponding to the holding holes 17a, 17a. It is for managing whether or not the operation of the apparatus has been set.

Therefore, according to the sliding door locking supplement device of this embodiment, it is possible to supplement the locking in conjunction with the locking by the existing locking means and to centrally monitor the complementation status.

When operating the sliding door locking complementary device of this embodiment, as shown in FIG. 3, the existing locking piece 4 is locked and rotated in the direction of the arrow 8 in the target sliding door, and this is rotated. When the locking piece 9 is locked, the lower structure 5a of the linking means 5 rises and pushes up the upper structure 5b in conjunction with this, and accordingly, the indoor side end of the rotation lock piece 3 is raised. It is pushed up and its outside end enters between the stopper piece 6 and the central side surface of the inner door 2 to be locked.

When the indoor end of the rotation lock piece 3 is pushed up in this way, the roll lever 11a of the abnormality detection switch 11 is pushed up, and the switch is turned off. At this stage, the operation pin 16 for holding the reset switch 14 in the off state is pulled out from the pin holes 15a and 15b of the cylindrical case 15 to allow the operation pin 16 to be turned on. It is to be inserted into the holding hole 17a located below the corresponding sliding door number of the centralized management board 17 and stored.

From the above, the operation start of the sliding door complementary device is completed. The locking operation of the existing locking piece 4 is almost completed, and the operation to be specially performed is only the movement of the operation pin 16 to the centralized control board 17, which can be performed extremely easily. Whether or not this operation start operation has been performed for all sliding doors can be easily determined only by checking whether or not the operation pin 16 is stored under each sliding door number on the centralized control board 17.

In the above state, even if the glass or the like of the sliding door is broken and the locking piece 4 is unlocked, the locked state of the locking piece 4 and the fixing piece 9 is released. The lock state of the rotation lock piece 3 is not released. That is, the lower structure 5a of the coordination means 5 is moved downward with the unlocking operation of the locking piece 4, but the lower structure 5a is separated from the upper structure 5b, and the upper structure 5b is pulled down. There is no such thing. Therefore, even if the existing locking means is broken, the locked state by the sliding door locking complementary device is maintained, so that the security effect can be further enhanced.

If the rotation lock piece 3 is unlocked and rotated by any means by a person who intends to enter illegally, the indoor end of the rotation lock piece 3 descends. As a result, the roll lever 11a of the abnormality detection switch 11 moves down, turning on the abnormality detection switch 11, turning on the power to the buzzer 12, and generating an alarm sound. Therefore, in this case, it is possible to inform the housekeepers etc. that the lock has been broken, and to issue an alarm to take an appropriate action, and this alarm sounds to inform the intention of the intruder to enter. It also produces the effect of withering.

In order to stop the operation of the sliding door locking complementary device of this embodiment, immediately release the locked state of the rotating lock piece 3, the abnormality detection switch 11 is turned on, and the buzzer 12 is alerted. First, a corresponding operation pin 16 is extracted from the centralized control board 17 and set in the cylindrical case 15 holding the reset switch 14 of the corresponding sliding door number. That is, as shown in FIG. 5, the operation pin 16 is inserted into the pin holes 15a and 15b of the cylindrical case 15, the roll lever 14a of the reset switch 14 is tilted backward, and the reset switch 14 is turned off.

Thereafter, the rotation lock piece 3 is unlocked. This unlocking operation can be performed using the locking hole 3c opened at the indoor end. If the drawstring is going to be lowered, it is sufficient to pull it. Otherwise, use the release operation rod provided with a locking piece at the tip and lock the locking piece into the locking hole 3c. Then, the inside end of the rotation lock piece 3 may be pulled down.

When the operation of the sliding door lock complementary device is stopped in this way, it goes without saying that the opening and closing of the sliding door become completely free.
