Abstract

PURPOSE:To surely report abnormality regardless of easy fixing by providing a detecting part in the aperture part of a base part with a damper means which detects detachment of the base part attached to a wall face. CONSTITUTION:A detecting lever 14a of a tamper switch 14 is projected from an aperture part 11a of a base part 11 of a wireless transmitter 1, and damper switches 14 and 15 have detecting pieces 14b and 15b depressed by depression of detecting levers 14a and 15a and a common terminal C and a normally open terminal M are connected, and the common terminal C and a normally close terminal B are connected by releasing depression of the detecting lever 14a. When the wireless transmitter 1 is normally attached to a wall face W, detecting levers 14a and 15a are depressed by the wall face W and a cover part 12 and an abnormal signal is not outputted. When it is detached from the cover part 12 or the wall face W, the abnormal signal is outputted. Thus, the abnormal signal is surely reported though the wireless transmitter 1 is easily fixed to the wall face with a both-sided tape.

), when the cover part 102 is attached to the base part 101, the convex part 1 of the cover part 102
02a detects the detection lever 1 of the tamper switch 104.
04a is pressed down, no abnormal signal is output, but when the cover part 102 is removed from the base part 101 as shown in FIG. 10(b), the pressing down of the detection lever 104a of the tamper switch 104 is released. Therefore, the conduction state of the tamper switch 104 changes and drives the internal circuit to output an abnormal signal, so even if the cover part 102 of the wireless transmitter 100 is removed by mischief, the abnormality is immediately notified. It can improve the reliability of the system.

However, in this wireless transmitter 100, the wireless transmitter 100 is
If the lever switch 104 is removed,
Since the base part 101 does not operate, it is necessary to securely fix the base part 101 to the wall surface W with screws or the like so that it cannot be easily removed. However, the wireless transmitter 100 was originally provided to simplify wiring construction. As it is,
There is a need for the development of a wireless transmitter that can reliably notify abnormalities even when fixed using a simple method.

[Problem 8 to be solved by the invention] The present invention proposed in view of the above circumstances is a tamper that generates an abnormal signal when the wireless transmitter itself is removed from the wall or the cover is removed. A wall-mounted wireless device with a tamper function that improves workability and reliability by adding functionality and ensuring that removal is detected even when the wireless transmitter is simply fixed to the wall. The purpose is to provide transmitters.

[Means for Solving the Problems] The present invention as claimed in claim 1, proposed to achieve the object 2, comprises: a base portion having an opening formed in a mounting surface that is attached and fixed to a wall surface; A configuration comprising: a cover part attached to the base part; and a tamper means having a detection part installed in the frontage part of the base part and detecting at least removal of the base part attached to the wall surface. has been done.

The present invention according to claim 2 provides the tamper according to claim 1.
The means is constituted by a tamper switch having a detection lever as a detection part, and the detection lever is arranged so as to protrude toward the wall surface through the opening of the space portion.

According to a third aspect of the present invention, the tampering means according to the first aspect is a detection section configured as a protrusion inserted from inside the base section so as to protrude toward the wall side through the opening section. , a biasing device having elasticity that biases the projecting piece toward the wall surface side, and a tamper switch having a detection piece and bringing the detection piece into contact with the biasing device. When removal is detected by the protruding piece of the tamper switch, the information is transmitted to the detecting piece of the tamper switch via the urging member.

The present invention according to claim 4 is characterized in that the tamper means according to claim 1 includes a light emitting element that outputs an optical signal to a wall side through the frontage part of the base part, and a light emitting element that outputs an optical signal from the light emitting element. A detection section configured by combining a light receiving element that receives reflected light through the above-mentioned frontage part, a light emitting circuit section that drives the above light emitting element, and a light receiving element that receives the light receiving signal from the above light receiving element and performs necessary signal processing. and a light-receiving circuit section that performs the following operations.

In the present invention as set forth in claim 5, the tamper means as set forth in claim 1 is constituted by a tamper switch in which the detection portion is a pull-out pin and operates in accordance with insertion or pull-out of the pull-out pin. A pin is vertically attached and fixed to the wall corresponding to the frontage of the base, and the tamper switch is arranged so that the pull-out pin protruding from the wall can be inserted through the frontage of the base. It is said to be composed of

[Function] In the present invention as set forth in claim 1, when the base portion of the wireless transmitter is attached and fixed to the wall surface, the detection portion of the tamper means does not detect removal of the base portion, so no abnormal signal is output.

However, when the base part is removed from the wall, the detection part of the tamper means detects the removal through the opening provided in the base part, and the tamper means drives the internal circuit and sends an abnormal signal to the wireless receiver. .

In the present invention as set forth in claim 2, when the base portion is attached and fixed to the wall surface, the tampering means is a tampering means.
Since the detection lever, which is the detection part of the switch, is pushed down by the wall through the opening in the base, no abnormality signal is output. On the other hand, when the base part is removed from the wall surface, the pressing down of the inspection roleper is released, so the internal circuit is driven by the tamper switch and an abnormal signal is sent to the wireless receiver side. When the base part is attached and fixed to the wall surface, the protruding piece which is the detection part of the tamper means is pushed by the wall surface, so the detection piece of the tamper switch is pushed down via the biasing device and no abnormal signal is output. However, when the base is removed from the wall, the protruding piece protrudes toward the wall due to the biasing device, releasing the tamper switch's detection piece from being pressed down.The tamper switch then drives the internal circuit and activates the wireless receiver. In the present invention according to claim 4, wherein the abnormal signal is provided on the side, when the base portion is attached and fixed to a wall surface that reflects light, the light output from the light emitting element of the detection portion of the tamper means is reflected on the wall surface. Since the tamper means does not output an abnormal signal, the tamper means does not output an abnormal signal. However, when the base section is removed from the wall surface, the light emitted from the light emitting element Pbl and reflected on the wall surface no longer enters the light receiving element, so the light receiving circuit section of the tamper means detects the interruption of the incident light and activates the internal circuit. In the present invention as set forth in claim 5, in which the abnormal signal is transmitted to the wireless receiver side by driving, when the base portion is attached and fixed to the wall surface, the bow serving as the detection portion of the tamper means attached perpendicularly to the wall surface. Since the punching pin is inserted into the tamper switch through the opening in the base, no abnormality signal is output. However, when the base part is removed from the wall surface, the pull-out pin is pulled out from the tamper switch, so the tamper switch drives the internal circuit and outputs an abnormal signal to the wireless receiver.

[Example] The present invention will be described in detail below with reference to the drawings.

FIG. 1(a) shows a longitudinal section of a wireless transmitter 1 according to a first embodiment of the present invention. This wireless transmitter 1 includes a base portion 11 fixed to a wall surface W with double-sided tape (not shown), a cover portion 12 attached to the base portion 11, and a support column 11b of the base portion 11 fixed with screws S. The printed circuit board 13 includes internal circuits such as an operation indicator light 16, as well as a tamper with a detection part 14a as a detection part.
A tamper means T consisting of a switch 14 is attached, and the printed circuit board 13 is mounted on the support column 11b of the base portion 11.
Detection Leper + when attached to 4. a is the base part 11
(corresponding to claim 2).

Further, a tamper switch I5 having a detection lever +5a is attached to this printed circuit board 13, and when the cover portion 12 is attached to the base portion 11 and the 11th digit is reached, the detection lever 15a is activated by the convex portion 12a of the cover portion 12. It is designed to be pushed down.

FIG. 1A shows the wireless transmitter 1 from the base part 11 side, and the tamper switch I is seen from the frontage part 11a.

(15b) is pushed down and common terminal C and normally closed terminal M
becomes conductive, and when the push-down of the detection lever 14a is released, the common terminal C and the normally closed terminal B become conductive.

When the wireless transmitter 1 having such a configuration is normally attached to the wall surface W, the tamper switch 14 detects the tamper switch 14 and the par 14a is attached to the wall surface W as shown in FIG. 1(a).
Since the detection lever 15a of the tamper switch 15 is pressed down by the convex portion 12a of the cover portion 12, no abnormality signal is output.

However, when the cover part 12 is removed from the base part 11, as shown in FIG. The internal circuit is driven and an abnormal signal is output. Furthermore, even if the cover part 12 is attached, when the base part 1 of the wireless transmitter 10 is removed from the wall surface W,
As shown in FIG. 1C, since the depression of the detection lever 14a by the wall W is released, the internal circuit is driven by the tamper switch 14 and an abnormality signal is output.

Therefore, even if the wireless transmitter l is simply fixed to a wall using double-sided tape, it is not possible to reliably notify the removal of the base part 1 in addition to the removal of the cover part I2 of the wireless transmitter 1. This makes it possible to improve workability and reliability.

No. 2121(a) shows a second embodiment of the present invention, and even if the tamper switch 15 of the first embodiment is not provided, the cover part and This makes it possible to detect the removal of both sides of the base part, whereas in the first embodiment, the printed circuit board 13 to which the tamper switch 14 is attached was fixed to the l\-base part] l side. On the other hand, this embodiment is different in that it is fixed to the cover section side.

This wireless transmitter 2 includes a base portion 21 fixed to a wall surface W with double-sided tape (not shown), a cover portion 22 attached to the base portion 21, and a support pillar 22a provided on the cover portion 22 with screws S. The printed circuit board 13 is fixed to the printed circuit board 13.

This printed circuit board 13 has the same structure as the printed circuit board of the first embodiment except that the tamper switch 15 is removed, and when attached to the support column 22a of the cover section 22, the detection lever 14a is activated at the opening 21a of the base section 21. It is made to stand out from the outside.

When the wireless transmitter 2 having such a configuration is normally attached to the wall surface W, the detection lever 14a of the tamper means/chip 14 is pressed down by the wall surface W, as shown in FIG. 2(a). No abnormal signal is output.

However, when the cover part 22 is removed from the base part 21, the tamper switch 1
Since the detection lever 14a of No. 4 is released from being pressed down by the wall surface W, the internal circuit is driven by the tamper switch 14 to output an abnormality signal. Moreover, even if the cover part 22 is attached, the wall surface W
When the base part 2I is removed, it is as shown in Fig. 2 (C
), the detection lever 14a is released from being pressed down by the wall W, so the internal circuit is driven by the tamper switch 14 and an abnormality signal is output.

By providing one tamper switch 14, it is possible to detect not only the removal of the cover part 22 but also the removal of the base part 21, which simplifies the internal configuration and improves workability and reliability. It is possible to improve the roar.

The abnormal signal is not output because it is pushed in by.

However, from the wall W to the base part 31 of the wireless transmitter 3,
When the protrusion 36 is removed, as shown in FIG. 3(t), the pressing down of the protrusion 36 by the wall W is released, so the protrusion 36 protrudes toward the wall W by the biasing member 35, and the tamper is removed. Since the detection piece 34a of the switch 34 is released from being pressed, the internal circuit is driven by the tamper switch 34 and an abnormality signal is output.

Therefore, since removal of the base portion 31 of the wireless transmitter 3 can be detected, even when the wireless transmitter 3 is simply fixed to a wall with double-sided tape,
Since removal can be reliably detected, ease of construction,
It is possible to improve reliability.

Further, in the tamper means T having such a configuration, the biasing tool 3
5, the stroke of the protruding piece 36 is set sufficiently larger than the stroke required to activate the detection piece 34a of the tamper switch 34, and an extra stroke is added.
Since the absorption can be done by bending the tool 35, for example, when attaching the base part 31 to the wall surface W, even if thick double-sided tape is used, the protrusion 36 will ensure that the The tamper switch can be activated, improving workability and reliability.

They are made to touch each other.

When the wireless transmitter 4 having such a configuration is normally attached to the wall surface W, as shown in FIG.
6 is pushed by the wall surface W and tampers the biasing tool 35.
Since it is pushed toward the switch 34 side, the detection piece 34a of the tamper switch 3.1 is pushed in by the biasing tool 35, and no abnormal signal is output.

However, when the cover part 42 is removed from the base part 4I, the tamper switch 3
Since the fourth detection piece 34a is separated from the biasing tool 35, the depression of the detection piece 34a is released, the internal circuit is driven by the tamper switch 34, and an abnormality signal is output. Moreover, even if the cover part 42 is not removed, when the base part 41 is removed from the wall surface W, the protruding piece 36 is pushed down by the wall surface W, as shown in FIG. 4(c). Since it is released, the protruding piece 36 is pressed by the urging member 35.
protrudes toward the wall surface W, the pressing down of the detection piece 34a of the tamper switch 34 by the biasing tool 35 is released, the internal circuit is driven, and an abnormality signal is output.

When the wireless transmitter 6 having such a configuration is normally attached to the wall surface W that reflects light, the wireless transmitter 6 shown in FIG.
), the light output from the light emitting element 54a of the detection section 54 of the tampering means T is reflected by the wall surface W and enters the light receiving element 54b, so that no abnormality signal is output from the light receiving circuit section.

However, when the cover part 62 is removed from the base part 61, as shown in FIG. 6(b), the light output from the light emitting element 54a and reflected by the wall surface W no longer enters the light receiving element 54b. The internal circuit is driven by the unit and an abnormal signal is output. Moreover, when the base part 61 of the wireless transmitter 6 is removed from the wall surface W,
As shown in FIG. 6(c), the light output from the light emitting element 54a and reflected by the wall surface W no longer enters the light receiving element 54b, so the internal circuit is driven by the light receiving circuit and an abnormal signal is output. Ru.

When the wireless transmitter 8 having such a configuration is normally attached to the wall surface W, as shown in FIG. Since the tamper switch 74 is inserted into the tamper switch 74, no abnormal signal is output from the tamper switch 74.

However, when the cover part 82 is removed from the base part 81, as shown in FIG. 8(b), the tamper switch 7
4 is pulled out, the internal circuit is driven by the tamper switch 74 and an abnormality signal is output. Furthermore, when the base portion 81 of the wireless transmitter 8 is removed from the wall surface W, the tamper switch 7 is removed as shown in FIG. 8(C).
