Description

[Detailed description of the invention] [Technical field] The invention includes a detector that detects the locking and unlocking of a door and the locking and unlocking of a crescent lock attached to a sliding door.
This invention relates to a locking confirmation device that can confirm the locked state from a remote location, prevent forgetting to lock the door, and ensure the safety and crime prevention of a house.

[Background technology]

Conventionally, crescent locks have been equipped with identification pieces that protrude when the lock is locked to confirm the locked state, but this requires a lot of effort as it requires going around each lock one by one and checking visually. If you forget to check other things, it becomes unsafe.

In addition, it is known that entrance/exit doors electrically detect and display only the closed state of the door.
Locking and unlocking itself must be visually confirmed, and if the door is forgotten to lock, the door may not be fully locked.

[Purpose of invention]

This invention locks and unlocks the crescent lock of sliding doors,
Install a detector that detects whether the door is locked or unlocked, making it possible to check whether the door is locked from a remote location, or using an alarm to warn against illegal entry, such as breaking the lock after it has been locked. The purpose of this invention is to provide a lock confirmation device that can improve crime prevention and safety.

As shown in FIGS. 2 and 3, the sliding door 2 has the crescent lock 5 attached to one door frame 3,
Further, the crescent lock 5, when locked, links the operating piece 6 that operates the first detector LS1. The other door frame 4 allows the movement of the actuating piece 6 only when the door frames 3 and 4 are closed, and one door frame 3 is placed in the door opening frame 7 that has been built in advance. A projecting piece 14 is attached to the door frame 4 to enable attachment of the door frame 4. The sliding door 2 has one door frame 3 located on the indoor side and the other door frame 4 on the outdoor side, and the upper ends of the door frames 3 and 4 are connected to the frame material 21 above the door opening frame 7. Slide the rail 22 provided on the. The door frames 3 and 4 are formed by arranging a rectangular frame material 23 having a cross section in the shape of a Japanese letter, and a groove provided on the opposing surfaces allows the glass plate 24 to be placed in the groove in front of the frame material 23. The vertical frame member 23 of the door frame 3 is fitted using a filled watertight material and is located in the center in the closed state.
In a, there is a partition piece 2 that partitions the groove on the back into the inside and outside.

The crescent lock 5 is pivotally supported by a support shaft on the outer surface of a box body 29 attached to the side surface of the vertical frame member 23a,
Due to its rotation, the vertical frame member 23b of the door frame 4 has a locking wall 30 that reduces the radius length and gradually becomes higher.
By engaging with the hook portion 33 at the tip of the receiving metal fitting 32 provided in the door frame, the door frames 3 and 4 are pulled together and pressed in opposite directions. An arm 39 is attached to the protruding end of the support shaft within the box body 29, and the arm 39 is connected to the actuating piece 6 via a connecting rod 41. The box body 29 has an elongated hole 43 in which a pin 42 that connects the tip of the connecting rod 41 and the actuating piece 6 slides, so that when the crescent lock 5 is rotated and locked, the actuating piece 6
can rise. The actuating piece 6 is made of a long channel member, and when the crescent lock 5 is in the unlocked state, its tip is approximately aligned with the upper frame member 23c, and therefore, when the crescent lock 5 is rotated, the upper frame member 23c is aligned with the upper frame member 23c. It protrudes from the frame material 23c.

The overhang piece 14 is attached to a frame member 44 above the door frame 4. The overhang piece 14 is formed using a long plate body 46 attached to the upper frame member 44. Long plate body 46
is made of a flexible material such as rubber or synthetic resin, and its sides protrude from the upper frame member 44 to a position beyond the upper part of the actuating piece 6 toward the indoor side, and the L-shaped fitting 4 is made of a flexible material such as rubber or synthetic resin.
7 is fixed to the upper surface of the frame material 44, and the protruding portion 46a, that is, the overhanging piece 14, passes through the upper surface of the frame material 23c on the door frame 3, thereby colliding with the operating piece 6 and suppressing its rise. . Moreover, the overhang piece 14 is
It extends continuously from the rear end of the door frame 4, and
A notch 15 is formed by cutting off at a position above the actuating piece 6 when the door frames 3, 4 are in a closed state, and the actuating piece 6 is allowed to rise only at the notch 15. That is, as shown in FIGS. 4 and 5, the crescent lock 5 operates only when the door frames 3, 4 are closed.

The first detector LS1 is, for example, a limit switch, and has its operating end exposed through an insertion hole 51 provided in the frame material 21 above the door opening frame 7, and is housed and fixed in a recess provided in the wall body. Ru. Note that the insertion hole 51
is opened above the actuating piece 6 when one door frame 3 is closed, and the first detector LS1 detects the actuation when the actuating piece 6 rises and contacts, and locks the crescent lock 5. Can be detected.

The lock 10 attached to door D is as shown in FIG.
It has a well-known structure that has a hook hole 13 and the lock rod 11 protrudes by key operation, etc., and the locking hole inside the receiving plate 16 into which the lock rod 11 fits is provided with an operating fitting 17. The second detector LS2, which operates in conjunction with the protrusion of the lock 1, is attached. The operation fitting 17 has one piece 17a facing the lock rod 11 and the other piece 17b facing the second detector LS2 bent into a V shape, and the plate spring 18 causes the one piece 17a to close to the door D.
is urged towards. Note that when the lock rod 11 enters, one piece 17a is pressed, the other piece 17b tilts backward, and the second piece 17a is pressed.
By moving away from the active end of the second detector LS2, the second detector LS2 can be turned on.

In the circuit to which the first and second detectors LS1 and LS2 are connected, as shown in FIG. 7a, a display L, which is a pilot lamp, for example, and an alarm W, which is a buzzer, are connected in parallel. An alarm circuit is provided. There is also a confirmation switch S1 in the circuit leading to display L.
However, there is also a security switch S2 in the circuit leading to the alarm W.
are intervening respectively. Note that the first and second detectors
LS1 and LS2 are connected to a selection switch SR consisting of a rotary switch, and the switch SR, by rotation, selects between the alarm circuit and only the first detector LS1, only the second detector LS2, or 1st, 2nd
This connection circuit in which the detectors LS1 and LS2 are connected in series can be selectively brought into conduction.

Note that when a plurality of sliding doors 2 are present, the first detectors LS1 attached to each sliding door 2 are connected in series, for example. In the circuit diagram of FIG. 7a, the first detector
It is represented and displayed as LS1. Note that the second detector
LS2 also represents the entirety of the second detectors LS2 of a plurality of doors D connected in series in FIG. 7a as LS2.

However, by switching the rotary switch SR to the individual connection circuit of the first and second detectors LS1 and LS2 and pressing the confirmation switch S1, the individual lock status can be confirmed on the display L, and the switch SR is set to the bb position. When switching, check the series state.
By then closing the security switch S2, any of the detectors will be activated in the event of an illegal break-in.
When LS1 and LS2 detect that the lock is unlocked or broken, the alarm W will sound and give a warning.

[Effect of idea]

In this way, the lock confirmation device of the present invention allows the operating piece of the sliding door that is connected to the crescent lock and activates the detector to move only when the door frame is in the closed state. Complete locking can be prevented. In addition, the detector that detects the crescent lock on the sliding door and the lock on the entrance door is connected to a confirmation switch, a security switch, and an alarm as an intervening display and alarm. You can easily and quickly check whether the door is locked or unlocked from a remote location, which prevents you from forgetting to lock it, and by turning on the security switch, you can prevent unauthorized entry from breaking the lock or opening the door after it has been locked. The alarm is activated and illegal intrusion can be detected, increasing the crime prevention effect. Further, since a selection switch is provided in the circuit of each detector, locking can be confirmed individually and simultaneously, and locking can be confirmed more easily.

In the lock confirmation device of the present invention, for example, as the lock 10, as shown in FIG.
The locking confirmation device of the present invention can be modified in various ways, such as operating the second detector LS2 via the locking device 7 at the time of locking.
