Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a crime prevention device attached to a shoji screen.

[0002]

[Prior art]

 Intruders (thieves) often appear in urban areas, whether they are single-family homes or condominiums, which makes people's lives uneasy. If a thief enters the room through a window, first identify if the shoji screen is locked or not, and if it is locked, open the glass near the lock with a glass and insert your hand from there to lock it. I had to remove it, opened the shoji, and invaded. In order to prevent intrusions, measures such as double locking the shoji locks in the house and installing auxiliary locks in addition to the locks were taken.

[0003]

[Problems to be solved by the device]

 Residents do not notice the thief's appearance, even if the locks are double-locked or the auxiliary lock is newly installed, and the residents do not notice when they are out, and when they are away It was a formal invasion of the room. Even if an auxiliary lock is installed outside the lock, it will not stop the invasion because it will only open more holes in the glass, so women living alone are especially frightened by the invaders of the god of death and feel at ease. It has become difficult to sleep in the crab.

In order to solve the above-mentioned problems, this security device makes a loud audible alarm when the lock is unlocked, which surprises a thief and makes it difficult for residents to enter the room. It was designed to notify that an abnormal situation had occurred (the appearance of a thief).

[0005]

[Means for Solving the Problems]

 The shoji crime prevention device of the present invention comprises a lock and an alarm device that is activated by opening and closing the lock. The swinging body that interlocks with the handle of a well-known lock is provided with a conductive protrusion and is fixed to the outside of the vertical frame. The lock box is provided with a conductive fixing plate that reaches the locus of rotation of the protrusion, and a buzzer for fixing the alarm device inside the switch and the vertical frame, a battery and a control circuit, and the switch as the protrusion of the lock. It is composed of a fixed plate.

[0006]

[Action]

 When the handle of the lock that closes the shoji screen is operated in the unlocking direction, the oscillating body rotates in conjunction with the handle, and at this time, the conductive protrusions that make up the switch of the alarm device mounted on the oscillating body become conductively fixed. Touching the board, the alarm buzzer sounds.

[0007]

【Example】

 The screen security device according to the present invention comprises a lock 1 fixed to the outside of a screen frame 3 and an alarm device 2 which is activated by opening and closing the lock 1.

As shown in FIG. 2, a known lock 1 is composed of a handle 4, an almost semicircular swing body 5 that interlocks with the handle 4, and a lock box 6 that supports and stores the swing body 5. The rocking body 5 is biased by the spring 7. A conductive protrusion 8 is provided on the rocking body 5 of the lock 1, and a conductive fixing plate 9 is provided in the lock box 6 so as to reach the track of rotation of the protrusion 8. The fixing plate 9 can also be attached to the back surface of the acrylic plate 10 by mounting the acrylic plate 10 inside the lock box 6. It is also possible to hang a spring 7 for urging the oscillating body 5 on the fixed rod 11 and the protrusion 8 provided in the lock box 6.

As shown in FIG. 1, the alarm device 2 connects a switch 12 that interlocks with the opening and closing of the lock 1, a buzzer 13 that is fixed inside the rectangular cylindrical vertical frame 3, a battery 14, a control circuit 15, and these. The switch 12 is composed of a protruding portion 8 that interlocks with the handle 4 of the lock 1 and a fixing plate 9 provided on the locus of the protruding portion 8. If the buzzer 13 of the alarm device 2, the battery 14, and the control circuit 15 are integrated, it can be easily installed in the vertical frame 3.

As shown in FIG. 3, the vertical frame 3 is provided with a mounting hole 17 for the lock 1, a lead wire insertion hole 18 for the alarm device 2, and a battery replacement window 19 on the side wall. It is provided slightly below the mounting portion, and the battery 14 can be replaced through the replacement window 19, the buzzer 13 of the alarm device 2, the battery 14, etc. can be installed and opened and closed with the lid 20. By lengthening the lead wire 16, the buzzer 13, the battery 14, and the control circuit 15 can be installed anywhere in the vertical frame 3.

The control circuit 15 of the alarm device 2 is configured such that once the switch 12 is turned on, the buzzer 13 sounds for at least 10 seconds even if the switch 12 is turned off immediately thereafter. The ringing time of the buzzer 13 can be shortened or lengthened by changing the control circuit 15. If a disconnecting switch (not shown) is provided in the control circuit 15, it is possible to forcibly stop the ringing of the buzzer 13.

When the handle 4 is operated from the locked state to the unlocked state in a state where the shoji equipped with the crime prevention device of the present invention is closed and cannot be opened by the lock 1, the swinging body 5 is operated according to the operation of the handle 4. Rotates as shown in FIGS. 4A and 4B, and the protrusion 8 provided on the rocking body 5 contacts the fixing plate 9. That is, the switch 12 of the alarm device 2 is turned on, the alarm device 2 is activated, and the buzzer 13 sounds.

FIG. 5 and FIG. 6 show the crime prevention device of the present invention for a butt shoji. The crime prevention device is provided with a conductive convex portion 21 at the tip of the rocking body 5 interlocking with the handle 4 and the handle 4 is closed. At this time, a switch 12 is built in the vertical frame 3 that receives the tip of the oscillating body 5. The switch 12 mounts a pair of fixing plates 9 on the locus of the convex portion 21, and the gap between the opposing fixing plates 9 is the convex portion 21. It is formed slightly narrower, and the fixing plate 9 is attached to a fixing portion 22 provided on the vertical frame 3. Others are formed in the same manner as in the above embodiment.

The security device of the present invention is not limited to the above-described embodiment. For example, a proximity sensor is attached in the vicinity of the space through which the oscillating body 5 passes, and the buzzer is sensed when the oscillating body 5 passes. 13 can be sounded, or a battery box 23 can be provided to simplify the replacement of the battery 14. It is also possible to connect the lead wire 16 connected to the protrusion 8 to the biasing spring 7 of the rocking body 5.

[0015]

[Effect of device]

 Since the crime prevention device of the present invention has the above structure, the following effects are exhibited. Since the alarm device switch is provided on the rocker that interlocks with the handle, if a thief tries to enter the room by turning the handle, the protrusion of the switch will contact the conductive plate and the buzzer will sound. As a result, the thief can unexpectedly stop the invasion and escape. In addition, the residents will be able to take measures such as notifying the police that the thief has appeared. Even when you are away, you can expect to stop the invading action with the warning sound of the buzzer, so you can live a safe life.
