Description

A crime prevention device that sends a signal when the attached object moves and continues to send a signal even when the object returns to its original position. It is.

In Patent Document 1, there is a key switch in which a switch and a cylinder are interlocked.
Used when opening the engine key of a car or the automatic entrance door of a condominium.
These switches do not have a function for self-holding signal transmission. When self-holding is required, a self-holding circuit must be assembled outside the switch.

Patent Document 2 has a window alarm switch having a self-holding function.
This is installed inside the window and has an electrical self-holding function that transmits a signal when the window is opened and continues to transmit a set time signal even when the window is closed.
However, this switch does not have a cylinder and cannot be operated with a key.
If this switch is to be operated with a key, a structure is required in which a cylinder that can be operated from the inside and outside is assembled to the switch for turning the power on and off.

The electric lock incorporates a door open / close switch and a lock / unlock switch.
However, these switches are simple switches. When the door is closed or locked again, the signal transmission stops and the signal transmission is not maintained.
Japanese Patent Laid-Open No. 7-246915 JP 2003-286785 A

If you need a signal to know that an object has moved, you want a switch that will continue to emit the signal even if the movement of the object is restored. I want a switch that is effective when I want to operate the switch with a key to avoid mischief or when I want to operate it from inside and outside.

The necessity of such a switch will be explained using a door as an example.
When an attempt is made to obtain an opening signal using a conventional key switch or electric lock, signal transmission stops when the door is closed.
In the conventional door opening signal, when the door is opened by breaking the lock locked by the thief, the signal transmission stops when the door is closed again. Even if the alarm buzzer sounds when the door is opened, the buzzer will stop after a few seconds after the door is opened.
The buzzer has a crime prevention effect if it keeps ringing even when the door is closed.

The conventional door opening alarm switch with a self-holding function does not have a cylinder, so it cannot be operated with a key, and cannot be operated from the outside when going out.
The conventional door opening alarm switch does not have a function of assembling the cylinders on the inside and outside of the switch set, and does not have such a structure.

There is a guard arm lock that opens a door to respond to visitors. The guard arm is hung at the time of customer service, and the door is opened for a while. At that time, signal transmission is not necessary. However, I thought about using the guard arm lock as an auxiliary to the main lock. The thief breaks the main lock while the guard arm is engaged, and even if the door is opened, the door is only slightly opened by the guard arm. Therefore, the thief cannot be put indoors unless the guard arm is destroyed. However, conventional guard arms and guard arm locks are weak in crime prevention and can be easily destroyed.
If the alarm sounds when the door is opened slightly and the alarm continues to sound even if the door is closed again, the thief should leave the place without destroying the guard arm. Thus, it is useful for crime prevention if there is a guard arm that can be operated from the outside of the room with a key to sound a buzzer when going out.

Attached to doors, lids and other objects and operated from the outside and inside / outside with a key to prevent mischief, alerts when doors or lids are opened or moved, doors and lids are closed, or objects are The challenge is to create a system switch with a self-holding function for signal transmission that will continue to report even if it returns to its original position.
Another problem is to create a system switch that is assembled by adding a switch that can be selected for the operation and stoppage of the switch to be assembled to the guard arm lock.

If the door opening switch that is triggered when the door is opened is attached to the door, you want to operate the switch with the key from the outside when you go out. When I go to bed, I want to use the thumb turn from inside.
When attached to the lid, I want to operate the switch with the key from outside the lid.
I want to operate the switch with the key from both sides of the partition plate.
In order to solve these problems, it is necessary to be able to freely assemble and remove cylinders and thumb turns inside and outside the switch set.
This can be solved by providing a dharma (7) for assembling the cylinder and thumb turn in the switch case (2). The technique of assembling a cylinder or thumb turn to this dharma is a well-known technique in the field of locks.

    In order to operate and stop the switch with a key lock or thumb turn, it is only necessary to combine the switch with a dharma.

With a door open signal switch, it has a self-holding function that triggers an alarm when it is opened once, and then continues even when the door is closed. This is the object of the present invention.
For this purpose, there are a method using a mechanical structure and a method using an electrical holding circuit.

Two examples of the function according to claim 2 for holding the signal transmission by the mechanical structure will be described.
One will be described with reference to FIGS.
A holding bar (12) having a holding spring (11) is attached to the dharma (7) for assembling the cylinder and thumb turn in the switch case. Install the opening switch (15) and trigger bolt (3) in the switch case. By linking the holding bar, the door opening switch, and the trigger bolt, the key and thumb turn knob (5) inserted into the cylinder (8) assembled to the dharma are operated to operate and stop the switch.
FIG. 3A shows the operation stop state, and no alarm is issued even when the door is opened and closed.
FIG. 3B shows that the door is closed during operation.
The dharma turns, and the holding bar attached to the dharma via the holding spring is caught by the trigger bolt, and the door opening switch cannot be pushed.
FIG. 3C shows that the door is opened in the driving state.
The trigger bolt protrudes and the holding bar comes off, and the holding bar presses the door open switch and reports.
FIG. 3D shows that the alarm is held with the door closed thereafter.
The alarm continues until the operation is stopped as shown in FIG.

A guard arm lock incorporating the system switch according to claim 1 (the invention according to claim 4) will be described.
4 and 5 show that the structure is assembled to the guard arm lock.
The guard arm is a metal fitting that can open the door only a little when responding to a visitor.
There is no need to report when opening the door.
An explanation will be given of when the guard arm is locked from the outside when it is out of the office and is in a driving state.
A thief breaks or unlocks the door's main lock, and the door opens only slightly because the guard arm is engaged when the door is opened. A thief cannot enter the house without destroying or unlocking the guard arm. If the buzzer sounds when the door is opened and the buzzer continues to ring even if the robber closes the door, the thief cannot continue to destroy the guard arm while the buzzer is sounding. So thieves can't enter indoors.

The same effect can be obtained even when driving from indoors when going to bed or when necessary.
The guard arm lock according to claim 6 is provided with an operation switch (24) in order to perform operation and operation stop as required. The arrangement of the operation switch (24) is shown in FIG. This is as shown in FIG.

One more mechanical structure will be described with reference to FIGS.
The holding bar (47) having the holding spring (48) is assembled to the dharma (44) so as to be interlocked, and the holding bar, the trigger bolt (43), and the opening switch (52) are assembled so as to be interlocked.
FIG. 6 shows the operation stop state.
FIG. 7A shows that the door is closed during operation.
The stopper (50) provided on the holding bar is caught by the trigger bolt, indicating the standby state.
FIG. 7B shows that the door was opened and the alarm was issued in the driving state.
FIG. 7C shows that the alarm is held with the door closed thereafter.
FIG. 8 shows a lock according to claim 4 in which the structure is incorporated in a lock case (55).
The dharma (56) for moving the dead bolt of the lock and the dharma (44) for operating the opening switch are separated. By splitting, the lock and the key for opening the door can be separated.
It is also possible to operate the lock with a thumb turn from inside the room and to operate the door opening switch with the key from inside the room.
This is effective when a thumb-turn or breakage occurs.
When it is desired to bring the opening switch into an operating state by the locking operation of the lock, the dharma (44) of the system switch and the dharma (56) for moving the deadbolt may be connected by a gear or a connecting shaft and linked. In that case, do not assemble a cylinder or thumb turn to the dharma of the system switch.

The method according to claim 3, wherein the signal transmission is held by an electrical method, will be described with reference to FIG. A switch having this holding function may be a commercially available switch.
The holding switch is assembled so as to interlock with the trigger bolt (73), and is not interlocked with the dharma (74). This switch is operated and stopped by moving the operation switch (81) connected to the holding switch with a dharma. The holding switch in the figure is a combination of a solenoid (77) and an opening switch (78).

FIG. 9A shows that the door is closed in a shutdown state.
FIG. 9B shows that the door is open in the operating state.
In this state, a current flows through the solenoid (77), and the door opening switch is held.
After that, even if the door is closed, the solenoid maintains the ON state of the opening switch.
When the dharma is turned and the operation switch is stopped, energization to the solenoid is stopped and the door opening switch is turned OFF.
FIG. 9A also shows a system switch according to claim 5 incorporating a battery and buzzer.

Conventional electric locks and key switches are merely simple switches as terminals, and even if batteries or buzzers are attached to them, they are not easy to use crime prevention devices.
This is because there is no function for holding notifications and no standby function, and there is no selection function.
The conventional door alarm buzzer attached to the indoor side of a door or window does not have a function of assembling a cylinder, and cannot be operated by a key combination from the inside and outside.
For this reason, in the conventional method, a control panel for centralized control is provided, and necessary circuits are incorporated into the control panel.
By using the system switch of the present invention, an effective crime prevention device can be self-contained simply by assembling a battery or a buzzer to the system switch.

An example in which the system switch according to claim 1 is attached to an entrance door of an apartment will be described.
The system switch can be selected on the indoor side as cylinder, thumb turn, or none.
Cylinder, thumb turn, or none can be selected outside the room.
This is possible by attaching and removing cylinders and thumb turns.
A description will be given with the cylinder attached inside and outside.

When you go out, set the system switch from the outside to the operating state using the key.
Suppose a thief destroys the main lock, feeds a cam, turns a thumb turn, tears it in other ways, and opens the door. The alarm sounds as soon as the door is opened, and the alarm does not stop even if the door is closed.
While the alarm is sounding, you can't look indoors and the thief will dissipate.
The same effect can be achieved by operating with a key from the inside.
The alarm cannot be stopped if there is no key by operating the key from inside or outside the room.
The system switch can be used as an alarm switch in various places because it can select cylinder, thumb turn, or none.

The crime prevention effect of the guard arm lock according to claim 6 will be described.
When going out, put the operation switch in the driving state when you go to bed and hang the guard arm.
Do not set the operation switch to the operating state when a visitor responds.
Explain when the main lock is broken by a thief while the operation switch is in operation.
When the door is opened, a buzzer will sound and the thief will not be able to enter the house until the guard arm of the door is destroyed.
There is one problem. If the thief puts his hand through the door opening and stops the operation switch, the buzzer stops.
In order to solve the problem, it is conceivable to operate the operation switch with a key.
Alternatively, a timer interlocking switch may be used that once energized, the energization stops after energization for several minutes.
The operation switch may be attached by extending the cord to a position where it is difficult to operate from outside.

It is a room side perspective view by the system switch of Claim 1. A. The AA cross section of FIG. 1 is shown. B. The same cross section is shown when the system switch is dug into the door and installed. A. The operation stop state door closing is shown in the BB cross section of FIG. B. The operation state door is closed and the standby state is indicated. C. The alarm status is indicated when the door is open. D. Then close the door to indicate that the alarm is held. The guard arm lock according to claim 6 shows the unlocked door operation stop state. A. The stand-by state is shown when the door is locked and closed. B. Shows the unlocked door notification status. The self-holding function according to claim 2 indicates a shut-down state door. A. The operation state door is closed and the standby state is indicated. B. The alarm status is indicated when the door is open. C. Then close the door to indicate that the alarm is held. It shows that the function of FIG. 6 was incorporated in the lock case. A.
