Description

Technical Field

[0001] The present invention relates to a technology effective for use in an adapter for a transmitter with a display lamp for issuing an alarm by being operated during a fire and a door for a disaster prevention related equipment storage box.

Background Art

[0002] Conventionally, a fire alarm system (fire alarm equipment) has been provided inside a building to notify of the occurrence of a fire. The fire alarm system is composed of a fire detector, a manual fire transmitter equipped with a push button switch, a receiver that receives detection signals from the fire detector and the fire transmitter, a bell for fire alarm, a display lamp, etc. Among these, the fire transmitter is installed at an appropriate height position on the wall surface of the corridor of the building. When a fire occurs, by strongly pressing the push button switch of the fire transmitter, a signal notifying of the occurrence of the fire is transmitted to the receiver, and an alarm sound is emitted from a bell provided near the fire transmitter, enabling people around to be notified of the occurrence of the fire.

[0003] The fire transmitter (hereinafter simply referred to as the transmitter) is generally disk-shaped. The transmitter body has a push button switch on the front surface and incorporates a circuit for transmitting a signal when the push button switch is pressed. It is installed by being embedded in the wall surface of the building or attached to the door of a disaster prevention related equipment box such as a fire hydrant box or a disaster prevention related equipment storage box. As an invention related to a disaster prevention related equipment storage box with a transmitter and a display lamp attached, there is, for example, one described in Patent Document 1, and as a design related to a door for a fire hydrant box with a transmitter and a display lamp attached, there is, for example, one described in Patent Document 2.

[0004] On the one hand, an indicating lamp is a device provided for indicating the installation positions of disaster prevention devices such as transmitters and fire hydrant boxes. Conventionally, bullet-shaped or dome-shaped ones were common, but in recent years, flat-type indicating lamps with a flat or disk-shaped front surface, and indicating lamps integrated with transmitters have also been put into practical use. As inventions related to indicating lamps attached integrally with transmitters, for example, those described in Patent Document 3 are available, and as inventions related to transmitters equipped with flat-type indicating lamps, for example, those described in Patent Document 4 are available.

Summary of the Invention

Problems to be Solved by the Invention

[0006] Conventional bullet-shaped indicating lamps protrude approximately 60 mm from the mounting surface, and due to their large protrusion amount, in recent years, they have been replaced with flat-type indicating lamps from the viewpoints of avoiding potential obstacles in passage and transportation, reducing damage accidents, etc., and improving aesthetics. There is also a desire to replace transmitters and indicating lamps installed on the wall surface of a building or the door of a disaster prevention-related equipment storage box with transmitters equipped with flat-type indicating lamps. However, since the transmitter with an indicator lamp has a housing for accommodating a lamp (LED), the housing of the transmitter with an indicator lamp is slightly larger than that of the transmitter alone. Therefore, when replacing a conventional indicator lamp or transmitter installed on the wall surface of a building or the door of a disaster prevention-related equipment storage box with a transmitter with an indicator lamp, since the opening provided on the mounting surface for passing the wiring of the original indicator lamp or transmitter or fitting a part of the main body of the transmitter is small, it may be necessary to perform a processing operation to enlarge the opening on the mounting surface when installing the transmitter with an indicator lamp. In addition, when attaching a transmitter with an indicator lamp to the door of a disaster prevention-related equipment storage box, it is possible to remove the original indicator lamp. However, if only the indicator lamp is removed, there is a problem that the opening provided for passing the wiring is exposed and the aesthetic appearance is degraded.

[0007] The present invention has been made paying attention to the above problems, and an object thereof is to provide an adapter that can attach a transmitter with an indicator lamp to a mounting surface without performing a process of enlarging the opening even if the opening provided on the mounting surface for an existing indicator lamp or transmitter is small. Another object of the present invention is to provide a door for a disaster prevention-related equipment storage box that replaces an original indicator lamp or transmitter with a transmitter with an indicator lamp and does not degrade the aesthetic appearance even if the unnecessary indicator lamp and transmitter are removed.

Means for Solving the Problems

[0008] In order to solve the above problems, the present invention In an adapter for a transmitter with an indicator lamp for attaching a transmitter with an indicator lamp, in which an indicator lamp and a transmitter having a push button operable from the front are integrally configured, to the front surface of a mounting plate, It has an annular shape with an opening through which at least the rear part of the housing of the transmitter can be inserted inside, and is provided with an annular body in which a female screw portion that can be screwed with a male screw portion formed on at least a part of the outer periphery of the housing of the transmitter or the outer periphery of the housing of the indicator lamp is formed on the inner periphery. A plurality of screw holes are formed in the annular body so that fixing screws for fixing the annular body to the mounting surface can be inserted or screwed in the front-rear direction.

[0009] Alternatively, in a transmitter with a display lamp and a push button operable from the front, in a transmitter-with-display-lamp adapter for attaching the transmitter-with-display-lamp, which is integrally configured, to the front surface of a mounting plate, an annular body having an opening through which at least the rear part of the housing of the transmitter can be inserted inside, and a plurality of locking pieces having claw portions engageable with a groove formed on the outer peripheral surface of the housing of the transmitter or the outer peripheral surface of the housing of the display lamp or the boundary between the outer peripheral surface of the housing of the transmitter and the outer peripheral surface of the housing of the display lamp are provided at predetermined intervals along the inner circumference. A plurality of screw holes are formed in the annular body so that fixing screws for fixing the annular body to the mounting surface can be inserted or screwed in the front-rear direction.

[0010] Alternatively, in a transmitter with a display lamp and a push button operable from the front, in a transmitter-with-display-lamp adapter for attaching the transmitter-with-display-lamp, which is integrally configured, to the front surface of a mounting plate, an annular body having an opening through which at least the rear part of the housing of the transmitter can be inserted inside, and an annular body having a female screw portion formed on the outer circumference, a holding ring having a male screw portion engageable with the female screw portion of the annular body formed on the inner circumference, and having a flange portion protruding so as to contact the front peripheral edge of the transmitter-with-display-lamp inserted forward into the opening of the annular body on the front end side. are provided. A plurality of screw holes are formed in the annular body so that fixing screws for fixing the annular body to the mounting surface can be inserted or screwed in the front-rear direction.

[0011] According to the adapter with the above configuration, since the adapter is fixed to the mounting surface and the transmitter with a display lamp is attached to the adapter, the transmitter with a display lamp can be attached to the front side of the mounting surface. Therefore, even if the opening provided on the mounting surface for the existing display lamp and transmitter is small, the transmitter with a display lamp can be attached to the mounting surface without performing a process of enlarging the opening. Also, the existing disaster prevention-related equipment storage box (or switch box) and the door for the disaster prevention-related equipment storage box can be reused.

[0012] Here, preferably, the hole for the screw is a funnel-shaped hole in which the large-diameter portion is larger than the diameter of the head of the fixing screw and the small-diameter portion is smaller than the diameter of the head of the fixing screw and larger than the diameter of the male screw portion of the fixing screw. Alternatively, the hole for the screw is composed of a first groove having a width larger than the diameter of the head of the fixing screw and a second groove continuous with the first groove in the thickness direction of the annular body, the width of which is smaller than the diameter of the head of the fixing screw and larger than the diameter of the male screw portion of the fixing screw. The second groove is formed in a state where it is located on the back surface side of the annular body, and two of them are provided in a state of being parallel to each other in the tangential direction from positions facing each other across the center of the annular body.

[0013] According to the above configuration, after attaching the fixing screw to a predetermined position on the mounting surface, the adapter is slid downward from above and attached to the fixing screw, and the transmitter with a display lamp is attached to the adapter, so that the transmitter with a display lamp can be fixed to the mounting surface, and thus the attachment work can be easily performed. Also, the existing disaster prevention-related equipment storage box (or switch box) and the door for the disaster prevention-related equipment storage box can be reused.

[0014] Moreover, another invention of the present application is In a door for a disaster prevention-related equipment storage box, which is composed of a panel provided in front of the storage portion of the disaster prevention-related equipment so as to be openable and closable, and the panel is formed with a first opening for attaching a display lamp and a second opening for attaching a transmitter. A transmitter with an indicator light and a push button that can be operated from the front is integrally configured and attached to the first opening or the second opening. A closing cover is attached to the second opening or the first opening where the transmitter with the indicator light is not attached.

[0015] According to the door for the disaster prevention related equipment storage box with the above configuration, since the opening generated by removing the indicator light or the transmitter can be closed with a cover, the existing disaster prevention related equipment storage box (or switch box) and the door for the disaster prevention related equipment storage box can be reused, and even if the original indicator light or transmitter is replaced with a transmitter with an indicator light and the unnecessary indicator light and transmitter are removed, the aesthetic appearance can be prevented from deteriorating.

[0016] Here, preferably, the closing cover has a plate-shaped cover body with a width of the minimum part larger than the diameter of the first opening or the diameter of the second opening, and a fixing member having a part with a width of the maximum part larger than the diameter of the first opening or the diameter of the second opening. A male screw body is erected on the back surface of the cover body, and a female screw part into which the male screw body can be screwed is provided on the fixing member. According to such a configuration, even when the diameters of the first opening or the second opening where the indicator light or the transmitter was attached are different, the cover for closing the opening can be attached to the door for the disaster prevention related equipment storage box.

[0017] Furthermore, preferably, the fixing member has a disk shape, and screw holes through which fixing screws can be inserted or screwed are formed at a plurality of locations on the peripheral edge. According to such a configuration, since the fixing member can be attached to the front surface of the door for the disaster prevention related equipment storage box, even when the door cannot be sandwiched between the closing cover and the fixing member, the first opening or the second opening where the indicator light or the transmitter was attached can be closed with the closing cover.

Effect of the Invention

[0018] According to the adapter for a transmitter with an indicator light according to the present invention, even if the opening provided for an existing indicator light or transmitter is small, the transmitter with an indicator light can be attached to the attachment surface without performing a process of enlarging the opening. Further, according to the door for a disaster prevention related equipment storage box according to the present invention, even if the original indicator light or transmitter is replaced with a transmitter with an indicator light and the unnecessary indicator light and transmitter are removed, there is an effect that the aesthetics does not deteriorate.

Embodiments for Carrying Out the Invention

[0020] Hereinafter, an embodiment of the adapter for a transmitter with an indicator light to which the present invention is applied will be described with reference to the drawings. The adapter for the transmitter in this embodiment has a function of attaching a transmitter with an indicator light to the front side of the opening of the attachment surface. Therefore, hereinafter, the configuration of the adapter 20 will be described together with the configuration of the transmitter with an indicator light 100 to be attached.

[0021] (First Embodiment) FIG. 1 shows the adapter 20 of the first embodiment together with the transmitter with an indicator light 100 to be attached. The transmitter with an indicator light 100 shown in FIG. 1 is composed of a transmitter main body 10 and an indicator light 15 integrated in a form that houses the transmitter main body 10. The transmitter main body 10 has a function of transmitting a signal notifying the occurrence of an abnormality to a receiver by strongly pressing a push button to turn on an internal switch when an abnormality such as a fire occurs. It includes a housing portion 12 having a push button 11 at approximately the center of the front surface and incorporating a circuit board, and an attachment base body 13 provided at the front end of the housing portion 12.

[0022] The mounting base body 13 is formed with an opening 13B at the center where the front surface of the push button 11 faces, and has a substantially flat front panel portion 13A that is oval-shaped in front view. A stepped portion 13C is formed so as to protrude rearward from the back surface of the front panel portion 13A. Partial male threads 13D1 and 13D2 are formed on the arcuate upper and lower surfaces of this stepped portion 13C.

[0023] The display lamp 15 includes a pair of display portions 51A and 51B located on both left and right sides of the transmitter main body 10, and a pedestal portion 52 having a storage recess capable of storing the housing portion 12 of the transmitter main body 10. An opening 53 through which the housing portion 12 of the transmitter main body 10 can be inserted is formed at the center of the bottom wall of the pedestal portion 52. As shown in FIG. 2, the transmitter main body 10 and the display lamp 15 are integrated in a state where the housing portion 12 of the transmitter main body 10 and the stepped portion 13C are stored in the storage recess. Further, recesses are formed on the back of the front panels of the display portions 51A and 51B of the display lamp 15, and a substrate on which a light-emitting element is mounted can be stored in the recesses. The display lamp 15 is formed of a transparent or translucent resin colored with a red paint, and when the light-emitting element is lit, the display portions 51A and 51B emit light in red.

[0024] The adapter 20 is entirely ring-shaped and is constituted by a nut (annular nut) having a female thread portion 20A on the inner peripheral surface that can be screwed with the partial male threads 13D1 and 13D2, and is configured to be fixable to the mounting surface 30 with screws 21. The transmitter 100 with a display lamp is fixed to the mounting surface 30 by screwing the housing portion 12 of the transmitter main body 10 through the opening 53 of the pedestal portion 52 of the display lamp 15 and screwing it into the female thread portion 20A of the adapter 20 fixed to the opening of the mounting surface 30. Further, when the transmitter main body 10 is screwed into the adapter 20, the pedestal portion 52 of the display lamp 15 is sandwiched between the mounting base body 13 and the mounting surface 30, so that the display lamp 15 is also fixed to the mounting surface 30 in a state of being integrated with the transmitter main body 10.

[0025] FIG. 3 shows the structure of the adapter 20 in detail. In FIG. 3, (A) is a front view of the adapter 20, and (B) is a longitudinal sectional view showing the inside cut along the line A-A of (A). As shown in FIG. 3(A), in this embodiment, two round holes 20b through which screws can be inserted are formed on the front side of the adapter 20 at positions facing each other across the center. As shown in FIG. 3(B), two screws 21 are inserted through the round holes 20b and are configured to be fixed by screwing onto the mounting surface 30.

[0026] The two round holes 20b are formed to be point-symmetrical. After screwing the screw 21 onto the mounting surface 30, when the screw 21 is fitted into the larger hole of the round hole 20b and then the entire adapter 20 is rotated counterclockwise, the screw 21 moves to the smaller hole of the round hole 20b, and thus the adapter 20 is fixed to the mounting surface 30 by the screw 21. Also, as shown in FIG. 3(B), the adapter 20 of this embodiment is provided with an internal thread portion 20A on the inner peripheral surface. When the partial male threads 13D1 and 13D2 of the transmitter main body 10 are screwed into this internal thread portion 20A and the transmitter 100 with a display lamp is mounted on the mounting surface by the adapter 20, a part of the opening side of the round hole 20b is blocked by the flange portions on the outer periphery of the front panel of the display portions 51A and 51B of the display lamp 15. The protruding amount of the flange portions on the outer periphery of the front panel of the display portions 51A and 51B can be increased to cover and hide the entire opening of the round hole 20b.

[0027] FIG. 4 shows a modified example of the adapter 20 shown in FIG. 3. In this modified example, instead of providing the two round holes 20b on the front side of the adapter 20, two screw holes 20c are provided on the back side of the adapter 20, and the adapter 20 is configured to be fixed to the front of the mounting surface 30 by inserting the screw 21 from the back surface of the mounting surface 30 and screwing it into the screw holes 20c. In addition, since screw insertion holes for screwing the transmitter and the indicator light may originally be formed near the opening 30A of the mounting surface 30, in such a case, the adapter 20 can be fixed to the mounting surface 30 using such screw insertion holes. Also, a configuration may be adopted in which no screw hole is provided on the back side of the adapter 20 and it is attached with a tapping screw from the back.

[0028] According to the adapter of the present embodiment configured as described above, since the adapter can be fixed to the front surface of the mounting surface and the transmitter 100 with an indicator light can be attached to the mounting surface using this adapter, there is an advantage that the attachment can be performed without performing a process of enlarging the opening originally provided on the mounting surface. In addition, since the adapter 20 has the above-described configuration, when the length of the flange portion on the outer periphery of the front panel of the indicator light 15 is short and, as shown in FIG. 3(B), the daruma holes 20b cannot all be covered, by eliminating the daruma holes 20b, it is possible to prevent a part of the daruma holes 20b from being visible from the front.

[0029] In the above embodiment, the partial external male threads 13D1 and 13D2 on the outer periphery of the transmitter body 10 are screwed into the female screw portion 20A on the inner periphery of the adapter 20 fixed to the mounting surface 30, so that the transmitter 100 with an indicator light is attached to the mounting surface 30. However, an external male thread portion may be provided on the entire outer periphery or a part of the housing of the indicator light 15, and the transmitter with an indicator light may be attached to the mounting surface 30 by screwing this external male thread portion into the female screw portion 20A on the inner periphery of the adapter 20 fixed to the mounting surface 30. In this case, the transmitter body 10 and the indicator light 15 are coupled with screws. Furthermore, it is preferable that the female screw portion 20A on the inner periphery of the adapter 20 is formed in accordance with the position of the daruma hole or the screw hole so that the transmitter 100 with an indicator light does not tilt left and right when the transmitter 100 with an indicator light is screwed and fixed to the mounting surface 30.

[0030] Furthermore, for example, a holding piece or an inner flange that protrudes so as to contact the side edge of the front surface of the transmitter body 10 from the front is provided at the front end of the opening of the indicator lamp 15, etc., so that when the male screw portion of the indicator lamp 15 is screwed into the female screw portion 20A of the adapter 20, a part of the transmitter body 10 is sandwiched between the adapter 20 to automatically fix the transmitter with an indicator lamp. Also, partial male threads 13D1, 13D2 may be provided on the outer periphery of the transmitter body 10, and a male screw portion that screws into the female screw portion 20A of the adapter 20 may also be provided on a part of the outer periphery of the housing of the indicator lamp 15.

[0031] (Second Embodiment) FIG. 5 shows the adapter 20 of the second embodiment. In FIG. 5, (A) is a front view of the adapter 20, (B) is a cross-sectional view showing the inside cut along the line A-A of (A), and (C) is a cross-sectional view showing the inside cut along the line B-B of (A). The adapter 20 of the second embodiment shown in FIG. 5 has a plurality (four in the figure) of locking pieces 22 having claws 22a at an intermediate height position along the circumferential direction on the inner peripheral wall of the adapter 20, instead of providing a female screw portion 20A on the inner peripheral surface of the adapter 20 to screw and fix the transmitter 10.

[0032] FIG. 6 shows a configuration example of a transmitter with an indicator lamp suitable for fixing by the adapter 20 shown in FIG. 5. As shown in FIG. 6, the transmitter body 10 of the transmitter in FIG. 6 is not provided with partial male threads 13D1, 13D2. However, in the transmitter shown in FIG. 6, a recess (groove) G is formed at the boundary between the outer peripheral surface of the transmitter body 10 and the outer peripheral surface of the indicator lamp 15 integrally coupled thereto. The adapter 20 shown in FIG. 5 is configured to fix the transmitter to the adapter 20 by engaging the claws 22a of the four locking pieces 22 at the parts (four locations) surrounded by the dotted line (circle) of this recess G.

[0033] The locking piece 22 has the front side ((upper side of (B))) of the adapter 20 as its free end. When the transmitter with a display lamp is inserted from the front side, the outer peripheral surface of the display lamp 15 enters the inside of the adapter 20 while deforming the locking piece 22. When the claw 22a aligns with the recess at the boundary between the outer peripheral surface of the transmitter body 10 and the outer peripheral surface of the display lamp 15, the locking piece 22 moves inward by the elastic restoring force, and the claw 22a of the locking piece 22 engages with the recess G to function as a retaining means. The number of the locking pieces 22 is not limited to four, and there may be one or more on each of the upper side and the lower side. Note that the adapter 20 is fixed to the mounting surface 30 by screws 21 inserted into bolt holes 20c provided on the front side of the adapter 20. The bolt holes 20c may be arcuate holes similar to those in FIG. 3, or may be fixed by screws 21 from the back side of the mounting surface 30 as shown in FIG. 5.

[0034] FIG. 7 shows a modified example of the adapter 20 shown in FIG. 6. In this modified example, as shown in FIG. 7(C), a pair of screw insertion grooves 20d, which is a combination of a groove having a width into which the head of the screw 21 can be inserted and a groove having a width into which the shank of the screw 21 can be inserted, are formed parallel to each other vertically along the tangential direction as shown in FIG. 7(A). These screw insertion grooves 20d have openings at their lower ends. After aligning the openings at the lower end sides of the screw insertion grooves 20d with two screws 21 that have been pre-screwed to the edge of the opening 30A of the mounting surface 30, the adapter 20 is moved downward, so that the screws 21 are relatively moved into the depths of the screw insertion grooves 20d, and the adapter 20 can be fixed to the front surface of the mounting surface 30.

[0035] Incidentally, when the state of FIG. 7(A) is viewed from the side, it is preferable that the screw insertion groove 20d is formed such that the bottom surface (step portion) of the wide groove into which the head of the screw 21 enters has an inclination that increases from the lower end opening side toward the upper inner part. This makes it easier to insert the screw 21 into the screw insertion groove 20d, and when the screw 21 is relatively moved to the inner part of the screw insertion groove 20d, by pressing the step portion of the screw insertion groove 20d with the lower surface of the head of the screw 21, even when a force to push the adapter 20 upward is applied, the adapter 20 can be prevented from easily moving and coming off the mounting surface 30.

[0036] (Third Embodiment) FIG. 8 shows the adapter of the third embodiment. In the adapter of the third embodiment, instead of providing the female screw portion 20A on the inner peripheral surface of the adapter (annular nut) 20, a male screw portion 20B is provided on the outer peripheral surface of the adapter 20, and a holding ring 23 having a female screw portion 23B that can be screwed onto the male screw portion 20B and a flange portion 23A on the inner side of the front end surface is provided.

[0037] The flange portion 23A of the holding ring 23 is formed with an opening so that the inner edge portion comes into contact with the outer peripheral edge portion of the display lamp 15 of the transmitter with a display lamp inserted so as to contact the front surface of the adapter 20. By sandwiching the edge portion of the display lamp 15 between the flange portion 23A and the adapter 20 with the holding ring 23, the transmitter 100 with a display lamp can be fixed to the mounting surface 30 by the adapter 20. Incidentally, the fixing of the adapter 20 to the mounting surface 30 is performed by a screw 21 inserted into a bolt hole 20c provided on the front surface side of the adapter 20. The bolt hole 20c may be a countersunk hole similar to FIG. 3, or as shown in FIG. 5, it may be fixed by a screw 21 from the back surface side of the mounting surface 30.

[0038] (Fourth Embodiment) FIGS. 9 to 11 show an embodiment of a door for a disaster prevention related equipment storage box to which the present invention is applied and an example of a cover for closing an opening for a display lamp provided on the door. Conventionally, as a disaster prevention related device, as shown in Fig. 9(A), there is a disaster prevention related device storage box 30 in which a conventional indicator lamp 33, acoustic holes 32 for a speaker and a bell, and a conventional transmitter 34 are provided on the front door 31. Also, although not shown, there are some in which an indicator lamp and a transmitter are provided on the door provided on the front surface of a fire hydrant box stored inside the wall of a building.

[0039] As described above, conventionally, bullet-shaped indicator lamps have been provided on the doors for disaster prevention related device storage boxes equipped with indicator lamps and transmitters. Also, it has been common for indicator lamps and transmitters to be provided separately. Since the bullet-shaped indicator lamp has a large protruding amount, it becomes an obstacle during movement or transfer, and there is a desire to replace it with a flat-type indicator lamp. Furthermore, since indicator lamp-equipped transmitters have become widespread, there are also cases where it is desired to replace existing disaster prevention related device storage boxes with indicator lamp-equipped transmitters as shown in the above-described embodiment.

[0040] However, when the conventional indicator lamp 33 and the conventional transmitter 34 provided on the conventional door 31 for the disaster prevention related device storage box are removed and an indicator lamp-equipped transmitter 100 is attached, as shown in Fig. 9(B), the opening 30A of the portion where the indicator lamp or the transmitter was attached will be exposed. This embodiment provides a cover suitable for closing this exposed opening. Fig. 9(C) shows a state in which the conventional transmitter 34 provided on the conventional door 31 for the disaster prevention related device storage box is replaced with an indicator lamp-equipped transmitter 100, and the opening (30A) for the indicator lamp is closed with the cover 40 of this embodiment. In addition, it is preferable that this cover 40 is formed of a resin or the like having the same color as the surrounding color, for example, the color of the disaster prevention related device storage box. For example, the disaster prevention related device storage box may change color from white to cream color. By preparing the cover 40 according to the color of the disaster prevention related device storage box to be attached, it is possible to close the opening with a cover of the same color as the storage box and make it less conspicuous.

[0041] As shown in FIG. 10, the cover 40 for closing the opening in this embodiment includes a disk-shaped cover body 41 having a diameter larger than the diameter of the opening for mounting an indicator light or a transmitter provided on the door of the disaster prevention-related equipment storage box, a male screw body 42 erected at the center of one surface of the cover body 41, and a disk-shaped annular nut 43 having a female screw portion 43a that can be screwed onto the male screw body 42. A plurality of screw insertion holes 43b are provided at the outer edge of the annular nut 43. The screw insertion hole 43b has a large-diameter portion larger than the head of the screw used formed at a predetermined depth from the front surface, and a small-diameter portion smaller than the head of the screw and smaller than the screw portion formed on the rear surface side. The annular nut 43 preferably has a diameter larger than that of a conventional indicator light or a conventional transmitter.

[0042] The cover 40 shown in FIG. 10 includes a disk-shaped cover body 41 and a disk-shaped annular nut 43 with a relatively large diameter, each having a male screw body 42 and a female screw portion 43a that can be screwed together with each other. Therefore, when the opening formed in the door 31 for the disaster prevention-related equipment storage box is small, the opening can be closed by sandwiching the panel of the door 31 between the cover body 41 and the annular nut 43 as shown in FIG. 11(A). When the opening is small, the opening can be closed as shown in FIG. 11(B). According to the cover for closing the opening of this embodiment, it is possible to cope with the doors of the disaster prevention-related equipment storage boxes with different opening sizes.

[0043] Also, when the panel of the door 31 cannot be sandwiched, a screw is inserted into the screw insertion hole 43b provided at the outer edge of the annular nut 43 to fix the annular nut 43 to the mounting surface, and the cover body 41 is screwed onto this annular nut to close the opening. Also, even when the panel of the door 31 can be sandwiched between the cover body 41 and the annular nut 43, when the opening is large, a screw may be inserted into the screw insertion hole 43b to fix the annular nut 43 to the back surface of the panel, and the cover body 41 is screwed onto this annular nut to close the opening. Thereby, it is possible to prevent the cover body 41 and the annular nut 43 in the screwed state from being displaced while screwed and a part of the opening being exposed.

[0044] As described above, the present invention has been described based on the embodiments, but the present invention is not limited to those of the above embodiments. For example, in FIG. 10, a circular cover body 41 of the cover 40 for closing the opening is shown, but the shape of the cover body 41 is not limited to a circle, and may be other shapes such as a polygon such as a square or a star shape. The annular nut 43 is also not limited to a circle, and may be other shapes such as a polygon such as a square or a star shape. For example, it may be composed of a small-diameter boss portion having a screw insertion hole 43b and a plurality of arm portions extending radially from the boss portion. Further, the annular nut 43 is easier to attach when it has a gripping portion like the outer peripheral portion in FIGS. 3 and 4. Also, in the first to third embodiments, the left and right light-emitting display portions 51A and 51B of the indicator lamp 15 combined with the transmitter main body 10 are shown in an arcuate shape, but shapes such as a crescent shape, a kamaboko shape, a triangle, or a ring shape may be adopted.

[0045] Also, in the above embodiment, the mounting base body 13 of the transmitter main body 10 is shown in an oval shape when viewed from the front, but the shape of the mounting base body 13 is not limited to an oval shape, and may be other shapes such as a circle, an ellipse, or a rectangle. Furthermore, in the above embodiment, the present invention has been described as being applied to a device combining a fire transmitter constituting a fire alarm system and an indicator lamp that can be combined with the transmitter, but the present invention is not limited to a fire transmitter, and can be widely used for transmitters for emergency train notifications installed on station platforms and level crossings. In addition, the transmitter with indicator lamp adapter and the closing cover of the above embodiment are applicable not only to the door of the disaster prevention related equipment storage box, but also to a transmitter and an indicator lamp that are individually attached to a switch box or the like embedded in a wall surface (panel).
