DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the security alarm device 10 according to the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the security alarm device 10 of this embodiment has a lid 16 which can be locked and opened and closed by inserting a key 12 into a lock 14 from the front side and operating the lock 14. The device main body case 18 is provided, and the back surface portion 18a side of the device main body case 18 is attached to the side surface of the offering box S1 as an example of the attachment target, as described in detail later. Inside the device body case 18, as shown in FIGS. 2 to 4, a detection unit K1 for detecting movements such as vibration, shaking, and tilting.
A holding circuit H1 that holds that the detection unit K1 has detected the movement, an alarm device BL that can generate an alarm sound while the holding circuit H1 is performing a holding operation, and the detection unit K1. , A holding circuit H1, and a power source D1 electrically connected to the alarm device BL.

Specifically, as shown in FIG. 2, for example, the apparatus body case 18 has a back surface portion 18a, upper, lower, left and right side portions 18b, and an opening Z1 located on the front side of the back surface portion 18a. The front shape consisting of the lid body 16 mounted so as to be closed is a square shape, and the front end portions of the four side portions 18b are folded at right angles as shown in FIG. A curved portion 18d is provided. A waterproof packing X1 is fixed to the upper and lower bent portions 18d of the bent portion 18d, and the front surface of the bent portion 18d on one side. The back surface of the lid 16 is in contact with the front surface of X1.

Further, one side end portion of the lid body 16, that is, the side end portion on the side where the lock 14 is not provided is bent in an L-shape toward the back surface portion 18a as shown in FIG. The angle portion 16a is formed as a closed portion, and another waterproof packing X2 is fixed to the front surface of the angle portion 16a. Then, the one side end of the lid body 16 is changed from the state shown by the phantom line in FIG. 4 to the state shown by the solid line inside the bent portion 18d through the opening Z1 of the device body case 18. So that the angle portion 1
The waterproof packing X2 fixed to the front surface of 6a comes into contact with the inner surface of the bent portion 18d. Since the lid body 16 is not structured to be attached to the apparatus body case 18 through a metal fitting such as a hinge, as described above,
It is difficult to break and remove the lid 16.

The lock 14 is provided at one end of the lid 16 and has a key receiving portion 1 having a key insertion port.
4a and a lock piece 14b that rotates in conjunction with the rotation operation of the key 12 inserted into the key receiving portion 14a, and has a contact point on the base end side that is linked to the rotation operation of the key 12. Switch W with built-in release switch KS that opens and closes
Is attached (see FIGS. 4 and 5).

Further, the lock piece 14d inserts the key 12 into the lock 14 and rotates the key 12 in the direction of arrow R1 as shown in FIG.
The bent portion 18d is rotationally displaced to the inside of the bent portion 18d.
I am stuck in the front side of. Also, the lock piece 1
By rotating the key 12 in the direction of arrow R2, 4d is rotationally displaced to a position away from the inside of the bent portion 18d, and can be pulled out to the front side of the bent portion 18d. The lock piece 14 is provided inside the bent portion 18d.
A spacer 18e that can contact d is attached,
By the lock piece 14d coming into contact with the spacer 18e, it is possible to prevent the lid 16 from rattling with respect to the apparatus body case 18.

However, the apparatus body case 18 is not limited to the shape shown in the illustrated embodiment, and may have, for example, a cylindrical shape, a cubic shape, or any other shape, and the lid 16 is not always necessary. It is not necessary to have a structure that has the cover 16 and the cover 16 may be omitted if it is not necessary depending on the purpose of use of the security alarm device 10. Further, the lock does not necessarily have to be of a type in which a key is inserted to lock or open, and it may be composed of other locks such as a hand-cranked combination lock (encryption lock).

Further, as clearly shown in FIGS. 2 and 3, a support plate 20 slightly smaller than the opening Z1 of the apparatus body case 18 is provided inside the apparatus body case 18 so as to be separated from the back side by a predetermined distance. The detection unit K1 is attached to one side of the front side of the support plate 20. The detection unit K1 includes a pendulum K2 and a detection switch LS that operates when the pendulum K2 swings by an external force of a predetermined value or more. This detection switch L
The lower portion 21a is fixed to the support plate 20 so that the S is located substantially at the center (see FIG. 3) of the side portion 18b of the apparatus body case 18, while the lower portion 21a covers the lid 1
It is attached to the front surface side of the upper portion 21b of the mounting plate 21, which is formed so as to be bent so as to stand up in six directions and further bent upward. A pendulum K2 is suspended below the detection switch LS, and the weight of the pendulum K2 can freely swing in all directions, as shown by the phantom lines in FIGS. 2 and 3.

The reason why the detector K1 using the principle of the pendulum K2 is used is to vibrate or shake the money box S1 to which the apparatus body case 18 is attached,
Alternatively, when the pendulum K2 of the detection switch LS is tilted and an external force of a predetermined value or more is applied, the detection switch LS is
It is possible to reliably detect vibrations, shakes, tilts, and other movements of the money box S1, and when the vibrations, shakes, tilts, and other movements of the money box S1 stop, and the swing of the pendulum K2 ceases, the detection switch LS. This is because it is possible to return to a state in which no movement such as vibration, shaking, and tilt of the money offering box S1 is detected. In order to prevent malfunction, the detection unit K1 detects a small amount of external force of a predetermined value or less on the pendulum K2 due to small movements such as vibration, shake, and tilt of the offering box S1. Movements such as vibrations, shakes, and tilts of the offering box S1 are not detected. still,
The predetermined value does not have to be a constant value, and may be set to various values depending on the purpose of use of the security alarm device 10.

However, the detector K1 does not necessarily have to include the pendulum K2 and the detection switch LS. For example, a sensor for detecting a motion such as vibration, shaking, or tilt is used without using the pendulum K2. For example, the configuration may be other than the above embodiment. In short, when the offering box S1 to which the apparatus body case 18 is attached is vibrated, shaken, or tilted, the detection unit K1 is detected.
However, any configuration may be used as long as it can reliably detect vibrations, shakes, tilts, and other movements of the offering box S1.

Further, the detection unit K on the front side of the support plate 20.

Further, a relay socket 26 including a relay C (see FIG. 5) functioning as the holding circuit H1 is arranged between the dry battery storage portion 24 and the detection switch LS, and the relay socket 26 has an external terminal 26a. Is connected to a wiring cord (not shown), and the relay C electrically holds that the detection switch LS has detected a movement such as vibration, shaking, or inclination of the offering box S1. There is.

On the back surface side of the lid body 16, an alarm device BL, such as a buzzer, which can emit an alarm sound while the relay C is performing a holding operation, is arranged. However, the alarm device BL does not necessarily have to be a buzzer having only the function of emitting an alarm sound, and may be, for example, an object that emits light or the like at the same time as the alarm sound, or sounds an alarm sound by an electronic sound. Can be one,
In addition, the alarm device BL is not necessarily the device body case 18
It does not have to be housed inside, and may be mounted outside the device body case 18. However, if the structure is such that the alarm device BL is housed in the case 18, there is no possibility that the alarm device BL is destroyed by an external force.

A cancel switch KS for canceling the holding operation of the holding circuit H1 is electrically connected to the alarm device BL to stop the alarm sound, and the cancel switch KS is released.
Is built in the switch W on the base end side of the lock 14, so that the lock 14 of the lid 16 that is lockably attached to the device body case 18 is opened (the key 12 is indicated by the arrow R).
Release switch KS by rotating in two directions)
The contact is opened (see FIG. 5) and the holding operation of the holding circuit H1 is released. On the contrary, when the lock 14 of the lid 16 is operated to lock (the key 12 is rotated in the direction of the arrow R1), the contact of the release switch KS is closed, and the holding circuit H1 is held. The motion can be accepted (however, of course, the swing of the pendulum K2 is stopped). As a result, the alarm sound of the alarm device BL continues to sound until the lock 14 of the lid body 16 is operated with the key 12, and when the operation is performed, the contact of the release switch KS which is in the closed state is opened. It opens, the holding operation of the holding circuit H1 is released, and the alarm sound of the alarm device BL is stopped. for that reason,
The alarm sound of the alarm device BL cannot be stopped easily, and the crime prevention effect is high.

Of course, the release switch KS for releasing the holding operation of the holding circuit H1 is, as in the above embodiment, an operation for locking or unlocking the lock 14 of the lid 16 lockably attached to the apparatus body case 18. It is not necessary to operate it in cooperation with, for example, the release switch KS
May be provided inside the device body case 18 instead of being built in at the base end side of the lock 14. If there is little need depending on the purpose of use of the security alarm device 10, the release switch KS may be omitted.
