DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire receiver. Alternatively, the present invention relates to a so-called wall-mounted fire receiver that uses a housing by being hooked on a wall or a pillar.

[0002]

2. Description of the Related Art FIG. 12 is a block diagram schematically showing a conventional general arrangement of, for example, the above-mentioned disaster prevention board and a relay board having substantially the same functions as the disaster prevention board. In the figure, reference numeral 1 denotes a disaster prevention board (fire receiver) electrically connected to a not-shown remote control device and a plurality of relay boards 3 installed in a tunnel 2. The disaster prevention board 1 and each relay board 3 are transmission lines 4
Are point-to-point connected by The relay panel 3 is connected to various terminal devices (not shown) of a section (block) to which the relay panel 3 belongs, that is, a fire detector, a water spray fire extinguisher, a fire hydrant, a manual alarm, and the like. Then, the relay board 3 is used to transmit information from these terminal devices and the disaster prevention board 1.
It plays a role of mutually transmitting instructions and the like from each other. Then, in the event of a fire, the disaster prevention board 1 displays warnings and related items. When necessary, the local manager goes to the place where the disaster prevention board 1 is installed and operates. This is done visually and manually by the local manager on the display screen. In this case, the operation or control of the display screen uses a mouse in addition to a keyboard such as various switches or numeric keys.

FIG. 13 is a schematic perspective view showing a conventional disaster prevention board. Among the conventional disaster prevention panels, a desk type panel as shown in the figure has a keyboard 7 and the like on the upper surface of a desk 6 projecting horizontally from the front of the rack 5 of the main body. A horizontal surface necessary for operating the mouse 9 used for controlling the display screen of the CRT 8 of the display device can be easily secured.

On the other hand, as a conventional fire receiver and the like, there is a so-called free-standing type which is rocker-like and stands upright on a floor surface, or a small box-like type which is hooked and fixed to a wall or a pillar. Similar to the desk-type fire receiver described above, a display unit for displaying a fire location and the like is arranged on the panel of the self-standing or wall-mounted fire receiver in addition to various switches for operation. In recent years, an LCD (liquid crystal display) or the above-described CRT has
Are often used. These display devices are equipped with a fire receiver, for example, a plan view of each floor of the building, information on fire, gas leaks, failures, disconnections, etc., related area numbers and addresses, and the sensor level history of analog sensors, etc. Can be displayed. For switching these screens and selecting items, for example, a CRT is usually used.
A touch panel method of pressing the screen with a finger has been used.

[0005]

The desk-type conventional fire receiver having a display device such as a CRT as described above has a horizontal desk-like body, so that a place for operating a mouse can be easily provided. However, the floor area including the desk is large, and the construction of a fire receiver that requires miniaturization has been a considerable problem.

On the other hand, in order to form a fire receiver having a small floor area, a so-called self-standing type or wall-mounted type using a vertical chassis is usually considered. However, the above-described self-standing or wall-mounted fire receiver does not have a console for operating a mouse, unlike the desk of a desk-type fire receiver as shown in FIG. Although a touch panel is exclusively used for this, the touch panel has a drawback that the display surface is frequently pressed with a finger, so that the display surface is easily stained. However, in order to be able to use a mouse on a free-standing type or a wall-mounted type, it is necessary to protrude a desk-type one from the front, which has the same problem as the above-described conventional example.

[0007] In addition, when the door of the housing is opened and a circuit or the like is inspected or repaired using a driver or a tester, the conventional fire receiver has no place to store the above tools. He was working with tools and other items on the floor. In other words, when inspecting the upper part of the receiver, the user was forced to squat down once to pick up a tool and then get up. In addition, when writing the inspection results and the like on paper, there is no horizontal space for writing, which is inconvenient.

[0008] Further, the conventional self-standing or wall-mounted type fire receiver has various disadvantages because a place for storing an instruction manual is not secured.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and can use and store a mouse.
In addition, a self-standing or wall-mounted fire receiver with a drawer-like console that allows tools to be left at the time of inspection and allows easy attachment of instruction manuals and cautionary notes etc. It is intended to do so.

[0010]

SUMMARY OF THE INVENTION A fire receiver according to the present invention is a self-standing or wall-mounted fire receiver having a front panel plate having a display device, wherein an opening is provided in the front panel plate. A chassis is provided in the receiver so as to be drawn substantially horizontally forward from the opening.

[0011]

According to the present invention, a drawer-shaped chassis is configured to be able to protrude forward from a predetermined position of a front operation panel portion of a housing (rack) of a self-standing or wall-mounted type fire receiver. When a drawer-shaped chassis with a small target depth is used, the bottom of this chassis can be used as a horizontal desk-shaped mouse operation plate, so you can use a mouse to select items on the display screen etc. It becomes a stand. On the other hand, when the drawer-shaped chassis is pushed inward, only the front panel portion is mounted on the front of the panel and the mouse is kept inside, so that it can be used as a mouse storage box. It is also possible to store necessary documents such as instruction manuals and, in some cases, tools in this space, and to attach a cautionary note.

[0012]

FIG. 1 is a front view showing an appearance of an embodiment of a self-supporting fire prevention panel (fire receiver) according to the present invention, and FIG. 2 is a state in which a mouse storage box shown in FIG. FIG. In both figures, a disaster prevention panel 10 is one in which a required electric circuit such as a CPU (not shown) is incorporated in a main body frame 11, and a display device such as a CRT 12 necessary for control operation of terminal equipment and the like is provided on a front panel. A switch, an indicator light 13, a keyboard 14, a printer 15, a clock 16 and the like are provided so as to be visually or manually operated. In addition, 1
Reference numeral 7 denotes a board storage section in which various boards are collectively arranged, and reference numeral 18 denotes a spare section in which electric wires are collectively stored.

3 and a relatively narrow vertical space between the chassis of the keyboard 14 and the chassis of the printer 15 and the timepiece 16. As is clear from FIG. 2, the bottom surface of the mouse storage box 19 is a mouse operation console 20, the front cover 21 of which is a front panel, and the upper surface is open. A mouse 23 for controlling and operating a display screen (not shown) of the CRT 12 is provided from the rear lid 22 to a mouse operation console 2.
0 on the upper surface of the chassis. It is preferable that a rubber plate or the like is laid on the upper surface of the mouse operation console 20 for use. Further, since the mouse storage box 19 is constituted by an attachment mechanism having a forward and backward movement mechanism including a rail (guide piece) and a stopper (bolt / nut) as described later, the mouse storage box 19 can fall down even when pulled out forward. , Do not fall.

In this manner, when using the mouse 23, the front cover 21 is unlocked and pulled out,
The operation is performed on the upper surface of the mouse console 20. And mouse 2
When the mouse storage box 3 is not used, as shown in FIG. 1, the mouse storage box 19 is pushed into the main body frame 11, and the front lid 21 is locked by, for example, screwing a screw hole 24 described later into the mouse storage box. The whole 19 is used as a mouse storage box without protruding from the front of the panel.

In this case, an instruction manual, a cautionary note, etc. of the disaster prevention board 10 can be attached to the front and back surfaces of the front cover 21 and a part of the upper surface of the mouse console 20. This is an advantage associated with the application of this configuration.

In the above embodiment, the mouse storage box 1
Although the forward and backward moving mechanism including the rail and the stopper has been conceptually described as a moving and locking mechanism associated with the installation of the ninth embodiment, some specific examples of the specific mounting mechanism will be described with reference to the drawings. I do.

FIG. 3 is a top view showing a state in which the mouse storage box is stored, and FIG. 4 is a top view showing a state in which the mouse storage box is pulled out. In both figures, reference numeral 19a denotes a mouse storage box attached to the front door 25 of the disaster prevention panel 10. The front door 25 is supported by the outer frame 26 and the hinge 27 of the housing, and can be opened in the direction of the arrow. ing. 29 is the front door 2
The stoppers A and 30 formed of bolts and nuts provided on the guide piece 28 vertically provided on the 5 are stoppers B formed of bolts and nuts mounted on the side plate of the mouse storage box 19a. Reference numeral 31 denotes a front panel 45 of the mouse storage box 19a.
It is a hand provided on the front part of.

In this case, since the front door 25 can be opened to the front left, the mouse storage box 19a is provided on the right side of the housing so that the guide piece 28 can be opened when the front door 25 is opened forward. Since the rear side hardly hits the housing, the mouse storage box 19a, that is, the chassis can be enlarged. When the mouse 23 is operated with the right hand, there is an advantage that the operation of the mouse 23 becomes easy.

FIG. 5 is an exploded perspective view for explaining a method of attaching the stopper to the mouse storage box and the housing. First, a pair of guide pieces 28 arranged at a predetermined interval has a front door 2 at one end.
5 made of an L-shaped rail material having a mounting surface 32 to
A hole 35 is provided near the mounting surface 32 of the side plate. The bolt 33 and the nut 34 are tightened through the hole 35 to form a stopper A29. Similarly, a stopper B30 is attached to the hole 35 provided near the rear wall of the side plate of the mouse storage box 19a.

Next, how to attach the mouse storage box 19a to the front door 25 will be described. First, the front door 25 is provided with an opening 56 (see FIG. 2) through which a frame of the mouse storage box 19a (hereinafter, referred to as a chassis) passes, and the mounting surface 32 is provided on the back side of the front door 25 near both ends of the opening. And a pair of guide pieces 28 are attached at predetermined intervals. After attaching the stopper A29 to the guide piece 28, the chassis is inserted from the front side. Attach the stopper B to the chassis in this state,
Finish the installation work. In this case, it is better that the bolt 33 is located inside the chassis for convenience in assembly.

Thus, as seen in FIG.
When the mouse storage box 19a is pulled out, the bolt 33 of the guide piece 28 and the nut 34 of the chassis collide, thereby serving as a stopper that prevents the mouse box 19a from being pulled out in front. Then, in the state of FIG. 4, the mouse 23 can be operated on the upper surface of the chassis as the mouse operation console 20. However,
In order to prevent the front panel 45 from penetrating to the back of the front panel 45 during insertion, it is convenient to add, for example, a collar 46 to both ends of the front panel 45 to make the lateral width larger than that of the opening. Instead of providing the collar 46, a stopper made of, for example, a bolt may be provided at the rear end of the guide piece 28.
When the width of the opening is equal to the width of the chassis 19a, the stopper A29 is unnecessary. In the present embodiment, as an example, a case where a stopper using a bolt and a nut is adopted is shown. Therefore, as shown in FIG. 3, D is inserted between the side plate of the guide piece 28 and the side plate of the chassis.
Although a gap is provided, the gap may not be provided when a stopper for a bolt and a nut is not required. The bolt 23 of the stopper A29 and the nut 3 of the stopper B30
Although the stopper 4 plays the role of a stopper when it hits, the stopper may be used by hitting bolts or nuts.

FIG. 6 is a partial explanatory view showing another embodiment of the longitudinal movement mechanism of the chassis. In this embodiment, an elongated hole 36 is provided in each of the side plates of the mouse storage box (chassis) 19a and the guide piece 28 instead of the hole 35 shown in the embodiment of FIG. See figure). In this way, between the long hole 36 of the chassis and the long hole 36 of the guide piece 28,
As shown in the lower diagram of FIG. 6, the bolts 33 and the nuts 34 are used to loosen relatively loosely through the spacers 55 with holes having a predetermined length. It is convenient to use a material having relatively high slipperiness such as a tetrafluoroethylene resin for the spacer 55. By doing so, the bolt used as a stopper,
There is an advantage that only one set of nuts is required on the left and right, no extra stopper is required, and the nut is not shifted back and forth more than necessary. As another mode, one of the mouse storage box 19a and the guide piece 28 is provided with a hole 35 in a conventional manner at a predetermined position, and is tightened with a bolt and a nut in the same manner to slide the chassis. It may be.

FIG. 7 is a schematic perspective view of a slide rail showing another example of the mechanism for moving the chassis back and forth, and FIG. 8 is an enlarged sectional view of a portion where the chassis is attached to the slide portion of FIG. In both figures, reference numeral 57 is used in place of the above-mentioned guide piece 28, and a slide rail whose U-shaped opening is bent further inwardly into a U-shape, and 47 is a slide rail of the slide rail 57 as seen in FIG. It is a U-shaped slide plate that fits into the inner protrusion and slides. The slide plate 47 has a hole 48 through which the mouse storage box 19 is inserted.
And is fixed to the side plate of the chassis 19b by screws. The method of attaching these members to the front door 25 is the same as in the case of FIG. 3, and a description thereof will be omitted.

FIG. 9 is a perspective explanatory view showing another embodiment of the mouse storage box. In this case, a front lid 21 having a flange 21a is attached to a front opening of the chassis 19c. The opening is provided with the front cover 21 at the cut portion of the chassis 19c, and a claw 49 provided in the thickness direction of the front cover.
With the chassis. The front lid 21 is provided with protrusions 50 protruding inward near both ends thereof. When the chassis is pushed in, the protrusions 50 are formed in the holes 51 formed in the front door 25.
Is fitted and mounted. When the mouse storage box 19c is pulled out, the front lid 21 can be tilted forward by the claws 49. By doing so, it is possible to improve the operability of the mouse.

FIG. 10 shows a state in which, for example, a precautionary note 53 for handling this fire receiver is attached to the back surface 52 of the front cover 21. Note that such a cautionary document may be attached to the front side. At the time of mounting, an instruction manual or the like may be stored on the mouse operation console 20, or the above-mentioned cautionary note or the like may be attached to a blank surface of the mouse operation console 20. This part can also be used as a simple tool storage area.

FIG. 11 is a top view showing the structure of another embodiment in which the mouse storage box is swung out (pulled open) like a Western door from the disaster prevention board. In the drawings, the same or equivalent parts as those in FIGS. 1 and 2 are denoted by the same reference numerals. In FIG. 11, the mouse storage box 61 is formed in a fan shape, and is rotatably supported on the disaster prevention board 10 by a rotation shaft 62. The mouse storage box 61 has a bottom surface serving as a mouse operation console 60, a front cover 64 serving as a front panel, and a stopper provided on the cover 65 so that the cover 65 does not fall down or drop when it is swiveled and pulled forward. 66 are provided.
