Description

[Technical field]

[0001] The present invention relates to a transmitter for use in an automatic fire alarm system. [Background technology]

[0002] Conventionally, in automatic fire alarm systems, a fire detector and a transmitter are connected to a detector line drawn from a fire receiver. The transmitter is installed on the wall of a hallway or the like in a security zone, and a protective plate made of transparent acrylic or the like is placed in a mounting hole opened in the red disk-shaped transmitter body. In the event of a fire, the protective plate is pressed down to turn on a push button switch placed behind it, which sends a fire notification signal to the fire receiver and sounds a fire alarm. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2011-060580 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the case of automatic fire alarm systems equipped with conventional transmitters, the fire transmitters are frequently pressed as a result of tampering, etc., which necessitates measures such as checking safety and explaining to the fire department that this is a tamper event, and the situation is one in which it is difficult to come up with countermeasures.

[0005] In order to prevent such misconduct, it has been considered to provide tamper-proof covers, etc. to prevent the operation of transmitters through such tampering; however, as there is a risk that such covers would come under the category of obstacles that impede the operation of transmitters as defined by law, a special application would have to be made to the relevant authorities to be exempt from the application of the regulations governing obstacles; and if an exemption is not granted, there is the problem that it would not be possible to provide tamper-proof covers, etc.

[0006] An object of the present invention is to provide a transmitter that can suppress and prevent manipulation by tampering or the like with a simple configuration without impairing the operational functions. [Means for solving the problem]

[0007] (Transmitter) The present invention is a transmitter that emits a signal when a push button switch is turned on by pressing a protective plate, The protective plate has a plurality of protrusions on a pressing operation surface, The protrusion portion is characterized in that at least one of a conical protrusion, a pyramidal protrusion, and a protrusion having a triangular cross section is formed.

[0008] (Transmitter:2) The present invention is a transmitter in which a push button switch is turned on by pressing a protective plate, A transmitter characterized in that the protective plate has a plurality of slits on the pressing operation surface.

[0009] (Transmitter:3) The present invention is a transmitter in which a push button switch is turned on by pressing a protective plate, The protective plate is a transmitter characterized in that at least one of an insect image and a reptile image is displayed on the pressing operation surface. Effect of the Invention

[0010] (Basic effect) The present invention is a transmitter in which a push button switch is turned on by pressing a protective plate, and the press operation surface of the protective plate is provided with a shape that evokes a sense of discomfort in the operator through touch and / or sight. Therefore, when an attempt is made to tamper with the transmitter, the feel and display of the protective plate create an uncomfortable feeling that cannot be predicted through normal operation, making it possible to discourage tampering. Since there is no need to cover the transmitter as with conventional tamper-proof covers, operability is not impeded in any way, and it is possible to deter and prevent tampering by suspicious persons, children, etc.

[0011] In addition, the form that visually reminds the operator of a sense of incongruity is displayed on the pressing operation surface of the protective plate in a manner that makes the operator hesitate to press with his / her finger, so that the strong sense of incongruity from the display of the protective plate can be felt and the operator can be deterred from mischievous operation. In particular, in the case where a child is about to mischief, the strong sense of anxiety can be given to the child and the operator can be deterred from mischievous operation.

[0012] (Effect of stereoscopic vision) In addition, since a shape that visually evokes a sense of incongruity for the operator is displayed in a stereoscopic manner on the pressing operation surface of the protective plate, if the operator tries to operate it for mischief, for example, he or she will see a cockroach or spider displayed in stereoscopic form and be surprised, mistaking it for the real thing, and even if he or she realizes that it is not real, the strong sense of incongruity and anxiety that remains will discourage the operator from trying to operate it any further, thereby making it possible to suppress mischievous operation.

[0013] (Effect of lenticular sheet) In addition, a lenticular sheet is provided on the pressure operation surface of the protective plate, which displays different contents when viewed from multiple different directions.The lenticular sheet is configured so that when viewed from a specified first direction, a specified operation guidance is visible, and when viewed from a specified second direction different from the first direction, a form that visually evokes a sense of discomfort for the operator is visible.Therefore, depending on the direction from which the transmitter is viewed, the operation guidance such as "press hard" displayed on the protective plate is visible, and when viewed from another direction, a form that visually evokes a sense of discomfort for the operator is visible, making it possible to deter tampering without impairing the operating function of the transmitter.

[0014] (Effect of viewing direction of lenticular sheet) In addition, the lenticular sheet is configured so that the first direction is the direction in which the lenticular sheet is viewed diagonally downward from above, and the second direction is the direction in which the lenticular sheet is viewed diagonally upward from below.Therefore, a tall adult can view the operation guidance for the protective plate by looking diagonally downward from above the transmitter, while short children can view a shape that gives the operator of the protective plate a sense of discomfort by looking diagonally upward from below, thereby discouraging tampering by children.

[Figure 6] An explanatory diagram showing the structure of a lenticular sheet DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] [Transmitter Overview] Fig. 1 is an explanatory diagram showing an overview of a transmitter according to the present invention. As shown in Fig. 1, a transmitter 10 is composed of a disk-shaped main body 12 and a switch storage section 18 provided on the back side. A protective plate 14 is placed and held in a mounting hole opened on the front side of the main body 12, and a push button switch 16 is placed inside the main body 12 behind the protective plate 14.

[0017] On the surface of the protective plate 14, for example, "press hard" is printed or engraved as an operation guidance, and a nameplate 15 is provided on the upper side of the protective plate 14.

[0018] The transmitter 10 is either directly embedded in a wall of a corridor or the like in the monitored area, or attached to an equipment storage box and embedded in the wall of the monitored area, and the sensor line drawn from the fire receiver is connected to a terminal block 20 provided on the outside of the switch storage section 18.

[0019] When the transmitter 10 is operated, the protective plate 14 is pushed firmly with a finger, which causes the protective plate 14 to come off the mounting hole and be pushed inward, thereby pushing in the switch knob of the push button switch 16 to turn it on, which in turn transmits a fire notification signal to the fire receiver and outputs a fire alarm.

[0020] [Embodiment of a protective plate that gives a tactile discomfort] FIG. 2 is an explanatory diagram showing a protective plate of a transmitter having a number of conical projections formed on the pressing operation surface, with FIG. 2(A) showing the front view and FIG. 2(B) showing the longitudinal section.

[0021] As shown in FIG. 2, the protective plate 14 of this embodiment has a number of conical protrusions 22 standing on the pressing surface, which is the front side of the plate body 14a made of transparent acrylic resin, in order to give the operator a sense of discomfort through touch.

[0022] When the protective plate 14 having a large number of conical protrusions 22 standing on the pressable operation surface is provided on the transmitter 10 of Figure 1, when the operator presses the protective plate 14 with his / her finger in an attempt to operate the transmitter 10, the large number of conical protrusions 22 formed on the pressable operation surface give the operator an operating sensation such as, for example, a bumpy, gritty, rough, gritty, prickly, rough, frayed, and / or rough feel.

[0023] The rough, gritty, rough, spiky, coarse, and / or rough feel of the protective plate 14 when operated will give an unexpected and strong sense of incongruity to someone who tries to operate it maliciously, thereby making it possible to discourage such mischievous operation.

[0024] Furthermore, since a large number of conical projections 22 are erected on the pressing operation surface of the protective plate 14, there is no need to cover the transmitter 10 as with a conventional tamper-proof cover, and the operability of the transmitter 10 is not impeded in any way, making it possible to discourage tampering by suspicious persons, children, etc.

[0025] In addition, numerous conical protrusions 22 are erected on the pressing operation surface of the protective plate 14 as a form that evokes a sense of discomfort to the operator through the sense of touch. In addition to this, any other suitable surface treatment may be used, such as numerous pyramidal protrusions, protrusions or slits with triangular cross-sections, which give an operating sensation of being rough, gritty, rough, prickly, rough, glossy, and / or coarse when pressed with a finger.

[0026] [Another embodiment of a protective plate that creates a tactile discomfort] FIG. 3 is an explanatory diagram showing a protective plate of a transmitter having an adhesive soft sheet disposed on a pressing operation surface, in which FIG. 3(A) shows a front view and FIG. 3(B) shows a vertical cross section.

[0027] 3, the protective plate 14 of this embodiment has an adhesive soft sheet 24 disposed on the pressing operation surface, which is the front side of the plate body 14a made of transparent acrylic resin. As the adhesive soft sheet 24, a soft silicone rubber sheet, a gel sheet, or the like can be used.

[0028] In this manner, when the protective plate 14 having the adhesive soft sheet 24 arranged on the pressing operation surface that is the front side of the plate body 14a is provided on the transmitter 10 of FIG. 1, when the protective plate 14 is pressed with a finger in an attempt to operate the transmitter 10, the adhesive soft sheet 24 formed on the pressing operation surface is pressed first, thereby giving the operator an operating sensation that includes sticky, gooey, sticky, and / or viscous properties, etc., and the operator is discouraged from operating it in a mischievous manner by receiving an unusual sensation that is not expected in normal operation.

[0029] [Display forms that evoke visual discomfort] FIG. 4 is an explanatory diagram showing the protective plate of a transmitter with insects and reptiles displayed on the pressable operation surface.

[0030] Figure 4(A) displays a cockroach image 26 as an insect image on the pressable surface of protective plate 14, Figure 4(B) displays a spider image 28 as an insect image on the pressable surface of protective plate 14, and further, Figure 4(C) displays a lizard image 30 as a reptile image on the pressable surface of protective plate 14.

[0031] The cockroach image 26, spider image 28, and lizard image 30 are creatures that are generally disliked, and it is preferable to use photographic images in order to create a realistic feel.

[0032] Moreover, the disliked insects may be caterpillars, bees, praying mantises, etc., other than cockroaches and spiders, and the disliked reptiles may be snakes, scorpions, etc., other than lizards.

[0033] Furthermore, since the protective plate 14 has a diameter of about 50 mm, it is preferable to display images of insects or reptiles whose actual size fits within the protective plate 14 in order to enhance the sense of realism.

[0034] When protective plate 14 having cockroach image 26, spider image 28, lizard image 30, etc., as shown in FIG. 4, displayed on its pressing display surface is provided on transmitter 10 of FIG. 1, when a person tries to press protective plate 14 with his / her finger in order to operate transmitter 10, he / she will feel a strong sense of discomfort or anxiety, which will discourage mischievous operation.

[0035] In particular, when a child tries to tamper with the device, the child will feel a strong sense of incongruity and anxiety, and will likely not want to touch the protective plate 14, thereby making it possible to inhibit tampering with the device.

[0036] [Protection plate with lenticular sheet] Figure 5 is an explanatory diagram showing the protective plate of a transmitter with a lenticular sheet on the press operation surface. Figure 5(A) shows the protective plate with the lenticular sheet and the line of sight, and Figures 5(B) and (C) show how the protective plate appears from two different directions.

[0037] 5(A), the protection plate 14 of this embodiment has a lenticular sheet 32 ​​disposed on the pressing operation surface of the plate body 14a. When the lenticular sheet 32 ​​is viewed from a plurality of different directions, different display contents can be seen.

[0038] In this embodiment, as shown in FIG. 5(A), when the lenticular sheet 32 ​​is viewed from above approximately diagonally downward as a first direction, as from viewpoint 34a, an operation guidance image 36 indicating “press hard” is visible on the protective plate 14, as shown in FIG. 5(B).

[0039] Furthermore, when the lenticular sheet 32 ​​is viewed from below approximately diagonally upward as a second direction, as shown in FIG. 5(A), as seen from viewpoint 34b, for example, a cockroach image 26 can be seen on the protective plate 14, as shown in FIG. 5(C).

[0040] FIG. 6 is an explanatory diagram showing the structure of a lenticular sheet, with FIG. 6(A) showing a plan view and FIG. 6(B) showing a cross section.

[0041] As shown in Figure 6, the lenticular sheet 32 ​​is configured by dividing the operation guidance image 36 and the cockroach image 26 shown in Figures 5(B) and (C) into narrow stripe images 26a, 36a and arranging them alternately, and forming a thin sheet structure on its surface in which multiple lenticular lenses 38 are arranged in pairs of the stripe images 26a, 36a.

[0042] When viewed from viewpoint 34a, as shown in FIG. 6(B), such a lenticular sheet 32 ​​appears as an operation guidance image 36 shown in FIG. 5(B) as an image based on stripe image 36a through lenticular lens 38, while when viewed from viewpoint 34b, the cockroach image 26 shown in FIG. 5(C) appears as an image based on stripes 26a through lenticular lens 38.

[0043] Furthermore, when a tall adult looks at the lenticular sheet 32 ​​provided on the protective plate 14 of the transmitter 10, the viewer will view it from above at an approximately diagonal downward angle from the viewpoint 34a shown in Figure 5(A), which allows the viewer to see the operation guidance image 36 of the protective plate 14 shown in Figure 5(B), thereby enabling reliable operation of the transmitter 10.

[0044] In contrast, when a short child looks at the lenticular sheet 32 ​​provided on the protective plate 14 of the transmitter 10, he or she will look up diagonally from below from the viewpoint 34b shown in Figure 5(A), which will result in the child seeing the cockroach image 26 on the protective plate 14 as shown in Figure 5(C), which will give the child a strong sense of incongruity and anxiety and is expected to discourage the child from touching the protective plate 14, thereby making it possible to inhibit mischievous manipulation by children.

[0045] [Embodiment of stereoscopic display] When cockroach image 26, spider image 28, lizard image 30, etc. are displayed on protective plate 14 shown in FIG. 4, the cockroach, spider and lizard images are displayed in a stereoscopic manner by alternately arranging stripe images of two images each of cockroach image 26, spider image 28 and lizard image 30 viewed from two directions corresponding to binocular parallax using lenticular sheet 32 ​​shown in FIG. 6.

[0046] When a user sees a cockroach, spider, lizard or the like three-dimensionally displayed on such a protection plate 14, the user mistakes it for the real thing and is surprised, and even if the user realizes that it is not real, the user is left with a strong sense of incongruity and anxiety, which makes the user lose the desire to operate it any further, thereby making it possible to suppress mischievous operation.

[0047] [Modifications of the present invention] The above embodiment takes the transmitter used in an automatic fire alarm system as an example, but is not limited thereto. For example, the transmitter can be similarly provided in a tunnel fire hydrant system or other disaster prevention systems.

[0048] In addition, in the above embodiment, insects and reptiles are used as examples of images that evoke a sense of disgust in the operator when displayed on the pressing operation surface of the protective plate, but the present invention is not limited to this. For example, a pattern or color that can give a strong sense of incongruity when viewing the protective plate may be displayed.

[0049] In the above embodiment, the pressing operation surface of the protective plate is provided with a form that evokes a sense of disgust in the operator by touch as shown in Fig. 2 and Fig. 3, and a form that evokes a sense of disgust in the operator by sight as shown in Fig. 4, but is not limited thereto. For example, the protective plate with many conical protrusions as shown in Fig. 2 or the protective plate with the adhesive soft sheet as shown in Fig. 3 may be combined with the display of a cockroach image, a spider image, or a lizard image as shown in Fig. 4.

[0050] The present invention includes appropriate modifications that do not impair the objects and advantages of the present invention, and is not limited to the numerical values ​​shown in the above embodiment. [Explanation of symbols]
