Description

[Technical field]

[0001] The present invention relates to a transmitter cover that is provided so as to cover a push button of a transmitter provided on the front panel of a fire hydrant device or a fire extinguisher box. [Background technology]

[0002] As a device for preventing tampering with a transmitter of a fire alarm system for general buildings, for example, Patent Document 1 discloses a "fire alarm tampering prevention device." Patent Document 1 discloses a tamper-proof device for a fire alarm that notifies an alarm system by breaking through a transparent sight glass and pressing a push button, and is equipped with an opening / closing door for opening and closing the sight glass, a detection means for detecting the opening and closing of the opening / closing door, and an alarm device that sounds an alarm for a predetermined period of time when the detection result of the detection means is that the door is open (see claim 1 of Patent Document 1).

[0003] Patent Document 1 describes the following effects. "When the door is opened, the alarm is activated. Anyone attempting to tamper with the device will be surprised and run away because the alarm is activated before they can press the push button. As a result, tampering with the fire alarm is prevented, and the activation of the alarm system as a result of tampering can be prevented." [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2010-165131 A Summary of the Invention [Problem to be solved by the invention]

[0005] The device in Patent Document 1 relates to a fire alarm for general buildings, and is intended to prevent false alarms caused by human error. However, the transmitters that are the subject of this invention are for reporting fires occurring inside tunnels and are attached to fire hydrants, fire extinguisher boxes, etc. Therefore, false alarms occur for reasons different from those caused by transmitters installed inside general buildings.

[0006] In areas with heavy snowfall, snow blows in and accumulates around the tunnel entrance. When vehicles pass over this accumulated snow, snow gets kicked up and presses the push button on the transmitter. For this reason, in such snowy regions, a cover is sometimes provided on the transmitter to prevent the push button from being pressed by snow kicked up by the vehicle.

[0007] However, if a cover is provided on the transmitter, it is necessary to open the transmitter cover before pressing the push button, which poses the problem of increased time and effort required for operation in an emergency.

[0008] The present invention has been made to solve such problems, and provides a transmitter cover that eliminates the need to open the transmitter cover when pressing a push button and can prevent the push button from being pressed by snow kicked up by a vehicle. [Means for solving the problem]

[0009] (1) The transmitter cover according to the present invention is provided to cover the push button of a transmitter provided on the front panel of a fire hydrant device or a fire extinguisher box, a side cover body provided to rise from the left or right side of the push button on the front panel when viewed from the front; The push button is characterized by having a front cover body that is provided continuously with the side cover body and that covers the left or right side of the push button when viewed from the front, and is positioned so that the right or left side is exposed.

[0010] (2) Furthermore, in the device described in (1) above, the side cover body is rotatably provided with the mounting portion as a rotation axis, and by rotating the side cover body and tilting it toward the front panel, the entire push button can be exposed when viewed from the front.

[0011] (3) In the device described in (2) above, a holding means is provided for holding the side cover body in an upright position. Effect of the Invention

[0012] The transmitter cover of the present invention comprises a side cover body that, when viewed from the front, rises from the left or right side of the push button on the front panel, and a front cover body that is continuous with the side cover body and is positioned so that, when viewed from the front, it covers the left or right side of the push button and exposes the right or left side.This eliminates the need to open the transmitter cover when pressing the push button, and makes it possible to prevent the push button from being pressed by snow kicked up by the vehicle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] As shown in Figs. 1 to 3, the transmitter cover 1 according to this embodiment is provided so as to cover the push button 6 of the transmitter 8 (see Fig. 4) provided on the front panel 5 of the fire hydrant device 3. When viewed from the front, the device is provided with a side cover body 7 that rises from the front panel 5 on the left side of the push button 6, and a front cover body 9 that is provided continuous with the side cover body 7 and that is positioned so as to cover the left side of the push button 6 and expose the right side when viewed from the front. Each component will be described in detail below.

[0015] <Fire hydrant equipment> As shown in Figures 2 and 3, the fire hydrant device 3 comprises a box-shaped housing 11, a front panel 5 having an opening provided on the front side of the housing 11, and a tilt-forward door 15 provided in the opening of the front panel 5 so as to be able to be opened and closed. In addition, a hose storage section and a fire extinguisher storage section are also provided within the housing 11. In addition, the push button 6 of the transmitter 8 and an indicator lamp 17 are provided in the portion of the front panel 5 between the hose housing section and the fire extinguisher housing section.

[0016] <Transmitter> When a person who discovers a fire presses the push button 6 on the transmitter 8, the fire is reported to the tunnel management office. The transmitter 8 is a waterproof type (waterproof transmitter), and unlike general transmitters for buildings, it does not have a structure for one-touch resetting of the flexiglass after pressing the push button 6, and the flexiglass will be damaged by pressing it. For this reason, the flexiglass is removed before pressing the push button 6 during inspection. There are also slide-type transmitters that address this issue, and during inspection, the flexiglass can be shifted along with the slide holder, allowing the push button 6 to be pressed without damaging the flexiglass.

[0017] <Transmitter cover> As shown in Figures 1 to 4, the transmitter cover 1 comprises a side cover body 7 that rises from the left side of the push button 6 on the front panel 5, and a front cover body 9 that is continuous with the side cover body 7 and is positioned so as to cover the left side of the push button 6 and expose the right side when viewed from the front.

[0018] Here, the left side of the push button 6 refers to the rear side in the traveling direction on the roadway 31 when the fire hydrant device 3 is installed near the wall on the left side of the traveling direction in the tunnel (see FIG. 7). In other words, in Japan, where traffic is on the left side of the roadway 31, the left side in a front view is the rear side in the traveling direction on the roadway 31.

[0019] In this embodiment, in addition to the side cover body 7 and the front cover body 9, an upper cover body 19 and a lower cover body 21 are provided. As shown in FIG. 1(b), the front cover body 9 has a window in the center made of a transparent acrylic plate 9a, so that the entire push button 6 can be seen even when the push button 6 is covered, as shown in FIG. 4(b).

[0020] 1, an example of the dimensions of the transmitter cover 1 is as follows: the height of the side cover body 7 is 50 mm, the length of the front cover body 9 in the left-right direction is 50 mm, the length of the front cover body 9 in the up-down direction is 100 mm, and the window of the acrylic plate 9a is 33 mm in the left-right direction and 66 mm in the up-down direction. However, the dimensions of the transmitter cover 1 are not limited to these.

[0021] The height of the side cover body 7 is related to the length that the front cover body 9 covers the push button 6, assuming that a finger will fit in when operating the push button 6. In other words, by increasing the height of the side cover body 7, it is possible to catch a large amount of snow flying in from diagonally behind, thereby reducing the area that the front cover body 9 covers over the push button 6. From the standpoint of operability, it is better if the area that the front cover body 9 covers over is smaller, but if the side cover body 7 is made taller, it will protrude more toward the front, so an appropriate height is set taking into account both of these factors.

[0022] In this regard, in this embodiment, as described below, in order to prevent snow flying from diagonally rear (a direction tilted 29° from a direction perpendicular to the front of the fire hydrant device 3 toward the direction of vehicle travel (see Figure 7)) from hitting the push button 6, the height of the side cover body 7 is set to 50 mm and the front cover body 9 is made to cover approximately half of the push button 6. It should be noted that the transmitter cover 1 only needs to prevent snow kicked up by the vehicle from hitting the transmitter 8 directly if it comes flying with great force; there is no need to consider how to deal with the case where the kicked up snow hits the transmitter 8 after bouncing off something or being blown by the wind.

[0023] Furthermore, in the transmitter cover 1 of this embodiment, the attachment portions of the side cover body 7 to the front panel 5 are attached to the front panel 5 by two hinges 23, so that the side cover body 7 is rotatably attached. This allows the side cover body 7 to rotate around the mounting portion as a rotation axis, and as shown in Figure 5, by rotating the side cover body 7 and tilting it toward the front panel 5, the entire transmitter cover 1 can be rotated and the entire push button 6 can be exposed when viewed from the front during maintenance, etc. In this embodiment, as shown in FIG. 5, the entire push button 6 can be exposed by rotating it by about 70 degrees. Note that "using the mounting part as a rotation axis" does not mean that the mounting part itself is an actual rotation axis, but rather, as shown in this embodiment, for example, by providing a hinge 23 near the mounting part of the side cover, the transmitter cover 1 rotates with the bottom part as a virtual rotation axis.

[0024] 1, a snap lock 25 is attached to the top cover body 19, and when the transmitter cover 1 is in an upright position (normal state), the snap lock 25 can be engaged with a locking portion 27 of the front panel 5 to maintain the upright position of the transmitter cover 1. The snap lock 25 and the locking portion 27 correspond to the retaining means of the present invention that maintains the upright position of the side cover body 7.

[0025] The hinge 23 may be a spring hinge that biases the transmitter cover 1 to an upright state (normal state), thereby maintaining the upright state of the side cover body 7. In this case, the spring hinge also functions as the retaining means of the present invention, and the snap lock 25 described above does not need to be used in combination.

[0026] The function of the fire hydrant device 3 equipped with the transmitter cover 1 configured as above when installed in a tunnel will be described with reference to Figs. FIG. 6 is a diagram showing an example of the arrangement of fire hydrant devices 3 installed in a watchman passage 29 inside a tunnel. When the fire hydrant is positioned as shown in FIG. 6 and a vehicle travels along the roadway 31 as shown in FIG. 7, analysis has revealed that the direction of snow kicked up by the vehicle that has enough force to press the push button 6 of the transmitter 8 will be inclined by 29° or more toward the direction of the vehicle's travel from a perpendicular direction to the front of the fire hydrant device 3.

[0027] At this time, if the push button 6 of the transmitter 8 is not covered, the push button 6 will be pressed by the kicked up snow. In this regard, by attaching the transmitter cover 1 of this embodiment, as shown in FIG. 4(a), the side cover body 7 and the front cover body 9 cover the push button 6 from snow that is flying at high speed, so that the push button 6 will not be pressed by flying snow. On the other hand, as shown in FIG. 4(b), even when the transmitter cover 1 is in place, the push button 6 is not entirely covered and the right side in the figure is exposed, so that the push button 6 can be pressed without having to perform operations such as opening the transmitter cover 1.

[0028] Furthermore, when performing maintenance on the transmitter 8, as shown in FIG. 5, the snap lock 25 can be unlocked and the transmitter cover 1 can be rotated toward the front panel 5 to expose the area around the push button 6.

[0029] As described above, the transmitter cover 1 of this embodiment is equipped with a side cover body 7 that is arranged to rise from the left side of the push button 6 on the front panel 5, and a front cover body 9 that is arranged to be continuous with the side cover body 7 and is positioned so that, when viewed from the front, it covers the left side of the push button 6 and exposes the right side.By applying this to a fire hydrant device 3 installed in a tunnel, it is possible to prevent malfunctions due to snow kicked up by vehicles, while allowing for uninterrupted operation in an emergency.

[0030] In the above embodiment, the case where the fire hydrant device 3 is installed on the left side of the traveling direction in the tunnel has been described as an example, but when one tunnel has only one lane direction, the fire hydrant device 3 may be installed on the right side of the traveling direction in the tunnel. In this case, a transmitter cover may be provided that includes a side cover body 7 provided so as to rise from the right side of the push button 6 on the front panel 5, and a front cover body 9 provided so as to be continuous with the side cover body 7, and arranged so as to cover the right side of the push button 6 and expose the left side in a front view. This can prevent malfunctions caused by snow splashed up on the right side of a traveling vehicle, as in the above embodiment, and can provide a transmitter cover that does not interfere with operation in an emergency at all.

[0031] In addition, in the above embodiment, an example was given of covering the push button 6 of the transmitter 8 installed in the fire hydrant device 3, but since a fire extinguisher box may be installed inside the tunnel and a transmitter 8 may also be installed in the fire extinguisher box, it is also applicable to a case where the push button 6 of the transmitter 8 installed in such a fire extinguisher box is covered.
