BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a simple installation type security sensor according to the present invention will be described with reference to the drawings.
[0020]
FIG. 1 is a partially enlarged sectional view showing a main part of a simple installation type security sensor according to the present invention.
[0021]
This simple installation type security sensor S is integrated into the main body case 2 with a mounting base 1 fixed to a window frame or the like indoor and outdoor, a human body detection sensor, a battery, and a warning means. And a main body cover 3 having a window hole portion 31 of the human body detection sensor.
[0022]
The mounting base 1 has a plurality of screw holes 11 formed on the back and upper surfaces thereof, and can be fixed to a roof side such as under an eave by inserting a wood screw into the screw holes 11.
[0023]
The screw hole 11 is appropriately adopted according to a state such as under the eave where the mounting base 1 is fixed. For example, when the mounting base 1 is fixed to a top surface such as under the eave, a wood screw is inserted into the screw hole 11 on the upper surface. It can be inserted and fixed. On the other hand, when it is fixed to a wall surface, it can be inserted and fixed through a wood screw in the screw hole 11 on the rear surface.
[0024]
Alternatively, a double-sided tape provided with a release paper may be adhered 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 eaves.
[0025]
In addition, if a display portion indicating the vertical direction is engraved or printed on the inside of the back surface of the mounting base 1, the mounting base 1 can be securely fixed without error in the vertical direction.
[0026]
The main body case 2 has a box shape opened downward, and a main body base 21 such as a substrate is provided therein, and a human body detection sensor for detecting a temperature change, a battery serving as a power source for the human body detection sensor, and the sensor are detected. An electronic buzzer 4 or the like as an alarm means for giving an alarm by mounting is mounted and incorporated.
[0027]
Although the detection sensitivity of the human body detection sensor is adjustable by a changeover switch, the sensitivity is weakened when the sensor is too far from the floor or the ground. It is desirable.
[0028]
In addition, one lithium battery is used for the above-mentioned battery.
[0029]
The main body cover 3 is formed so as to close an open surface of the main body case 2, and has a window hole 31 substantially at the center thereof into which a makeup cover of the human body detection sensor fits.
[0030]
Further, a sound hole 32 for sounding an alarm sound of the electronic buzzer 4 is formed in the main body cover 3, and a ring-shaped fitting convex frame 33 is provided upright on the inner surface side of the sound hole 32. .
[0031]
Reference numeral 5 denotes a cylindrical surrounding member that is opened up and down.
[0032]
The surrounding member 5 is formed so that the upper end inner wall substantially fits the electronic buzzer 4 and the lower end outer wall is fitted inside the fitting convex frame 33 of the main body cover 3.
[0033]
In addition, the inner wall of the surrounding member 5 is formed so as to be thick on the side of the main body cover 3 so that the sound of the electronic buzzer 4 flows smoothly.
[0034]
A waterproof sheet 6 is provided between the surrounding member 5 and the fitting convex frame 33 of the main body cover 3 to waterproof the electronic buzzer 4.
[0035]
Further, the waterproof sheet 6 can be attached to the inner surface of the sound hole 32 of the main body cover 3 with an adhesive or the like.
[0036]
The surrounding member 5 thus configured is positioned by inserting the lower end into the fitting convex frame 33 of the main body cover 3 with the waterproof sheet 6 interposed therebetween, and when the main body cover 3 is attached to the main body case 2, the upper end thereof becomes an electronic buzzer. 4 can be fitted around it.
[0037]
Since the surrounding member 5 is interposed between the electronic buzzer 4 and the sound hole 32 of the main body cover 3, a resonance space 51 that resonates the sound of the electronic buzzer 4 is formed inside the surrounding member 5. Will be done.
[0038]
Therefore, the sound of the electronic buzzer 4 resonates the waterproof sheet 6 via the resonance space 51, so that the volume of the electronic buzzer 4 can be increased.
[0039]
In addition, since the surrounding member 5 is detachably fitted to the main body cover 3, it is easy to remove the surrounding member 5 and cover the electronic buzzer 4.
[0040]
On the other hand, in the present embodiment, the surrounding member 5 is fitted to the fitting convex frame 33 of the main body cover 3. However, the surrounding member 5 is fitted to the electronic buzzer 4, and the upper end thereof is fixed to the main body base 21 in advance. You can also.
[0041]
If the surrounding member 5 is fixed to the main body base 21 in advance in this way, the surrounding member 5 can be positioned without forming the fitting convex frame 33, so that the position does not shift.
[0042]
FIG. 2 is a partially enlarged sectional view showing a main part of another embodiment of the simple installation type security sensor according to the present invention. Note that portions common to FIG. 1 are denoted by common numbers, and description thereof is omitted.
[0043]
This simple installation type security sensor S is provided with a support projection 32 a protruding toward the main body case 2 at the center of the inner surface of the sound hole 32 of the main body cover 3.
[0044]
The support projection 32a has a substantially arc-shaped vertical section, and the waterproof sheet 6 is adhered to the support projection 32a.
[0045]
As described above, the central portion of the waterproof sheet 6 which is covered with the lower end opening of the surrounding member 5 and is sandwiched and fixed between the surrounding member 5 and the main body cover 3 is structured to be lifted and supported by the support projection 32a. The waterproof sheet 6 is pinched and fixed in a state of being bent in an arc shape.
[0046]
Therefore, the tension of the waterproof sheet 6 can be relaxed, and the sound of the electronic buzzer 4 can be easily transmitted to the waterproof sheet 6 via the acoustic space 51, and the volume of the electronic buzzer 4 can be further increased.
[0047]
In the present embodiment, the case where the main body cover 3 and the main body case 2 are formed separately is illustrated. However, the main body case 2 incorporates a human body detection sensor, an alarm unit, and a control circuit, and The same effect is obtained even when the main body cover 3 having the window hole 31 of the detection sensor is integrally formed and combined.
[0048]
FIG. 3 is a diagram showing the use state of the simple installation type security sensor according to the present invention.
[0049]
The simple installation type security sensor S configured as described above is used as follows.
[0050]
First, the mounting base 1 is separated from the main body case 2 to which the main body cover 3 is fixed, 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.
[0051]
At this time, the vertical direction of the mounting base 1 is checked on a display unit or the like, and is fixed correctly.
[0052]
Next, the main body case 2 is fitted to the fixed mounting base 1 with the main body cover 3 facing downward, and the operation switch of the main body cover 3 is operated to activate the human body detection sensor to set the alert mode.
[0053]
Then, when a person enters this sensor range, the human body detection sensor detects it, and the electronic buzzer 4 serving as an alarm means sounds an alarm sound to prevent intrusion indoors.
[0054]
【The invention's effect】
According to the present invention, the following effects can be obtained.
[0055]
According to the simple installation type security sensor according to the first and second aspects, since the surrounding member is interposed, the resonance space is formed in the surrounding member, and the volume of the buzzer can be increased.
[0056]
According to the simple installation type security sensor according to the third aspect, the surrounding member can be made detachable, and the misalignment can be prevented by being fitted into the fitting convex frame of the main body cover.
[0057]
According to the simple installation type security sensor according to the fourth aspect, since the surrounding member is fixed to the main body base, no displacement occurs.
[0058]
