DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a horizontal blind embodying the present invention will be described below with reference to the drawings.

The horizontal blind shown in FIG. 1 has a plurality of slats 3 from a head box 1 via ladder cords 2.
Is suspended and supported, and a bottom rail 4 is attached to the lower end of the ladder cord 2.

An elevating cord 5 suspended from the head box 1 is inserted into the slat 3, and one end of the elevating cord 5 is guided inside the head box 1 toward the one end side thereof and hangs down from the head box 1. The operation code 7 is connected via the code equalizer 6. The bottom rail 4 is suspended and supported at the other end of the lifting cord 5.

Therefore, the bottom rail 4 can be lifted and lowered by pulling the lifting cord 5 out of the head box 1 by operating the operation cord 7 or by pulling it into the head box 1 due to the weight of the bottom rail 4. Each slat 3 can be raised or lowered based on the elevation of the.

An operating rod 8 is hung at one end of the head box 1, and the slat 3 is moved by rotating the operating rod 8 via a slat angle adjusting device arranged in the head box 1. The angle can be adjusted by the phase.

A swing sensor 9 is attached to one end of the bottom rail 4. The swing sensor 9 functions as a detection element of a crime prevention device that detects a swing of the bottom rail 4 and detects an intruder.

The electrical construction of the security device will be described with reference to FIG. A setting switch 11, a release switch 12, and a relay coil 13 are connected in series between the high potential side terminal and the low potential side terminal of the power supply 10.

The setting switch 11 is a switch that is pressed when setting the operation of the security device, and is a normally open switch that is conductive only when it is pressed. The release switch 12 is a switch that is pressed when releasing the operation of the security switch, and is a normally closed switch that is in a non-conducting state only when the switch is pressed.

A relay contact 13a and a timer 14 are connected in series between the high potential side terminal and the low potential side terminal of the power source 10. The low potential side terminal of the relay contact 13a is connected to the high potential side terminal of the release switch 12. The relay contact 13a is a normally open contact that becomes conductive when the relay coil 13 is excited.

Therefore, when the setting switch 11 is pressed, the relay coil 13 is excited, the relay contact 13a becomes conductive, and the relay coil 13 is self-held in the excited state. When the setting switch 11 is pressed,
The supply of the power supply 10 to the timer 14 is started, and the relay contact 13a is maintained in the conductive state even after the pressing of the setting switch 11 is released, so that the supply of the power supply 10 to the timer 14 is maintained.

The timer 14 starts the count-up operation of time based on the supply of the power source 10 and brings the contact 14a into a conductive state after a predetermined time has elapsed. The contact 14a
Is a normally open contact that becomes conductive based on the count-up signal of the timer 14.

When the release switch 12 is pressed,
Since the exciting current to the relay coil 13 is cut off, the contact 13a is opened, the power supply to the timer 14 is cut off, and the timer 14 is reset.

Between the high-potential side terminal and the low-potential side terminal of the power source 10, the contact 14a and the rocking sensor 9 are connected in series, and the light emitting diode 15 is connected in parallel to the rocking sensor 9. There is.

When the contact 14a becomes conductive, the rocking sensor 9 is supplied with power 10 and
The light emitting diode 15 is turned on. The swing sensor 9
Is activated based on the supply of power to enter an operating state in which the swing of the bottom rail 4 can be detected, and when the swing is detected, the contact 9a is brought into a conductive state. Further, the light emitting diode 15 displays that the swing sensor 9 is in an operating state based on the lighting.

The contact 9a is a normally open contact which becomes conductive based on the detection signal of the swing sensor 9. The contact 9a and the alarm buzzer 16 are connected in series between the high potential side terminal and the low potential side terminal of the power source 10. The contact 9a
When is turned on, the power source 10 is supplied to the alarm buzzer 16 and an alarm sound is emitted.

Such a crime prevention device may be housed in the bottom rail 4 or attached to a wall surface or the like excluding the swing sensor 9 and electrically connected to the swing sensor 9. Good.

Next, the operation of the security device constructed as above will be described with reference to FIG. When the setting switch 11 is pressed at bedtime or when going out (step 1),
When the timer 14 starts the count-up operation (step 2) and the timer 14 finishes the count-up after a predetermined time (step 3), the power supply 10 is supplied to the rocking sensor 9 (step 4) and the light emitting diode 1
5 is turned on.

When the bottom rail 4 shakes in this state (step 5), the alarm buzzer 16 emits an alarm sound (step 6). When the swing of the bottom rail 4 is stopped, the alarm sound is stopped, and such an operation is repeated until the release switch 12 is pressed (steps 5 to 7).

When the release switch 12 is pressed, the timer 14 is reset, the power supply to the swing sensor 9 is cut off, the swing sensor 9 is deactivated, and the operation of the security device is released. (Step 8).

With the horizontal blind provided with the security device constructed as described above, the following operational effects can be obtained. (1) When the security device is activated, the bottom rail 4
An alarm sound can be generated based on the vibration of the. Therefore, if this horizontal blind is installed inside the window, a suspicious person entering through the window will touch the blind and touch the bottom rail 4
If you shake, you can reliably detect the intrusion of a suspicious person by the alarm sound. (2) If the operation of the security device is released, no alarm sound is emitted even if the bottom rail 4 shakes. Therefore, when the crime prevention function is unnecessary, it is possible to stop the output of the unnecessary alarm sound. (3) Since the warning sound is not output based on the damage of the blind, it is not necessary to repair the blind after the warning sound is output. Therefore, the repair cost after the alarm operation can be reduced. (4) Since the detection operation of the rocking sensor 9 can be started after a predetermined time has elapsed since the setting switch 11 was pressed, even if the occupant operates the blind within a predetermined time after pressing the setting switch 11, it is useless. No warning sound is emitted. (5) By turning on the light emitting diode 15, it is possible to confirm that the swing sensor 9 is in an operating state. (6) By pressing the release switch 12, it is possible to easily stop the alarm sound and release the crime prevention function.

The above embodiment can be modified as follows. -Instead of the swing sensor 9, a proximity sensor that detects a change in the distance between the bottom rail 4 and the floor surface or the window frame may be used. -In addition to horizontal blinds, it can be applied to roll blinds, pleated curtains, tuck-up curtains, etc. The alarm device may be a lighting device that illuminates the room when the alarm is activated. -The alarm device may be an alarm buzzer, any means for notifying the resident, or a device for notifying an external security company or the like.
