DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A simple installation type security sensor according to the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a simple installation type security sensor according to the present invention, and FIG. 2 is an exploded perspective view of a main body case.

The simple installation type security sensor S includes an attachment base 1 fixed to a window frame or the like indoor or outdoor, a human body detection sensor,
The battery and the main body case 2 having a built-in alarm are integrally assembled.

The main body case 2 may be constituted by assembling the cover body 23 and the base body 21 separately from each other as shown in FIG.

Hereinafter, each member will be described.

The mounting base 1 is fixed to a suitable place inside or outside the building such as a window frame. The mounting base 1 is formed by a pair of left and right side pieces 13, 1.
3 to form a frame body that is opened with the front part 1A and the bottom part 1B as insertion holes.

For example, in order to fix the mounting base 1 to an indoor ceiling or the like, a screw hole 11 formed in the upper surface piece 11 is used.
a and 11a can be screwed by inserting a wood screw or the like. On the other hand, in order to fix the mounting base 1 to a wall surface of a building or the like, a wood screw or the like is inserted into a similar screw hole (not shown) formed in the back piece 12. Can be inserted and screwed.

Alternatively, a double-sided tape provided with a release paper may be attached to the outside of the rear surface and the outside of the upper surface of the mounting base 1, and the release paper may be removed to fix the mounting base 1 under the eaves.

In addition, a sign indicating the vertical direction is engraved or printed on the inside of the back piece 12 of the mounting base 1 so that the mounting base 1 can be securely fixed without making a mistake in the vertical direction.

Then, the pair of side pieces 1 of the mounting base 1
Above the inner surface of each of 3 and 13, a guide recess 14 having a stepped support surface portion 14a is formed.

The main body case 2 includes a human body detection sensor, a battery,
A warning means is built-in, and is detachably inserted into and removed from the insertion opening of the mounting base 1 and is integrally assembled to the mounting base 1.

As shown in FIG. 2, the main body case 2 of this embodiment detects a human body detecting sensor for detecting a temperature change, a battery as a power source thereof, and a sensor on a box-shaped base 21 opened downward. Alarm means for alarming with a buzzer or the like is built in.
2, a detection window 23a of a human body detection sensor on which the
3b, cover body 23 formed with sound hole 23c of alarm buzzer
Are assembled together.

As shown in FIG. 1, the guide recesses 1 of the mounting base 1 are provided on the rear side on both upper ends of the main body case 2.
4, and projecting pieces 24, 24, which are slid and inserted in the support surface portion 14 a and are supported by the support surface portion 14 a, project sideways.

Therefore, the projecting pieces 13, 13 of the main body case 2
Is inserted into the guide recesses 14, 14 of the mounting base 1, the lower surfaces 24 a of the protrusions 13, 13 are guided while being supported by the support surface 14 a of the mounting base 1, so that the main body case 2 can be easily mounted. It can be attached to the base 1, while it can be easily removed by pulling out the main body case 2.

Although the detection sensitivity of the above-mentioned human body detection sensor is adjustable by a changeover switch, the sensitivity becomes weak when the sensor is too far from the floor or the ground.
It is desirable to attach the battery to about 8 to 2.2 m, and one lithium battery is used as the battery. A locking recess 15 that runs in the up-down direction is further formed on each inner surface of the mounting base 1, and fits into the locking recess 15 when slidingly fitted into a corresponding portion of the main body case 2. The locking projection 25 is projected.

According to such a structure, the locking projection 24 of the main body case 2 is attached to the mounting base 1 when it is fitted.
The engagement recess 15 is elastically deformed and fits, so that the main body case 2 can be fixed so as not to be accidentally detached or moved, and when the engagement protrusion 24 is fitted into the engagement recess 15. Click feeling is obtained.

In the center of the upper surface piece 11 of the mounting base 1, two notches 16, 16 are formed, and a holding tongue piece 17 having a projection 17a projecting downward is formed. 2 The corresponding portion on the upper surface is provided with a convex portion 17a of the holding tongue piece 17.
Is further formed.

According to such a structure, when the main body case 2 is mounted on the mounting base 1, the pressing tongue piece 7 is elastically deformed and is fitted and fixed in the fixing recess 26 of the main body case 2. The main body case 2 can be further fixed so as not to be accidentally detached or moved, and a click feeling can be obtained when the main body case 2 is fitted into the fixing recess 26.

Further, a notch 18 is formed in the center of the lower end of the back piece 12 of the mounting base, and is cut out in a semicircular shape into which a finger can be inserted.

By forming such a notch 18, even when the main body case 2 is fitted into the mounting base 1,
Because the back of body case 2 can be pushed in with a finger,
The main body case 2 can be easily removed.

In this embodiment, as shown in FIG.
The cover 23 serving as the surface of the main body case 2 is provided with a removable lid 24e that covers the battery housing 23d, and is fixed from the bottom surface of the battery housing 23d that is exposed when the cover 24e is removed. Screw in the screw 24f,
It is structured to be integrally assembled and fixed to the mounting base 1 (not shown) through the base body 21.

With this structure, although the main body case 2 is fixed to the mounting base 1 with the fixing screws 24f,
The fixing screw 24f can be hidden by the battery and the lid 24e to make it hard to see, and can prevent the main body case 2 and the like from being stolen.

FIG. 3 is a diagram showing the use state of the simple installation type security sensor according to the present invention.

The simple installation type security sensor S configured as described above is used as follows.

First, the mounting base 1 and the main body case 3 to which the main body cover 4 is fixed are separated, and the mounting base 1 is fixed to a wall surface such as under an eave or a top surface with a wood screw.
When the mounting surface is an aluminum sash or the like, the mounting base 1 is attached with double-sided tape.

At this time, the display portion 12 of the mounting base 1 is checked, and the display portion 12 is correctly fixed in the vertical direction.

Next, the main body case 2 is fitted to the fixed mounting base 1 with the decorative cover 3 facing downward, and the switch of the operation window 44 of the main body cover 4 is operated to activate the human body detection sensor and to be alert. Mode.

When a person enters the sensor range,
The human body detection sensor detects the alarm and sounds an alarm sound by an alarm means to prevent intrusion into the room.
