Description

[Technical field]

[0001] The present invention relates to a technology that is useful for use in an adapter for a transmitter with an indicator light that is operated to sound an alarm in the event of a fire, and in a door for a box for housing disaster prevention related equipment. [Background technology]

[0002] Conventionally, fire alarm systems (fire alarm equipment) are installed inside buildings to notify the occurrence of a fire. A 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 fire transmitter, a fire alarm bell, an indicator light, etc., and the fire transmitter is installed at an appropriate height on the wall of a building, such as a corridor. When a fire breaks out, the discoverer presses the push button switch of the fire transmitter hard, which transmits a signal notifying the occurrence of a fire to the receiver and also emits an alarm sound from a bell installed near the fire transmitter, thereby notifying people in the vicinity of the occurrence of a fire.

[0003] A fire transmitter (hereinafter simply referred to as a transmitter) is generally disk-shaped, and the transmitter body is equipped with a push button switch on the front and a built-in circuit for transmitting a signal when the push button switch is pressed. It is installed by being embedded in the wall of a 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. An invention relating to a disaster prevention related equipment storage box equipped with a transmitter and an indicator light is described in, for example, Patent Document 1, and a design relating to a fire hydrant box door equipped with a transmitter and an indicator light is described in, for example, Patent Document 2.

[0004] On the other hand, indicator lights are devices that are installed to indicate the installation positions of disaster prevention equipment such as transmitters and fire hydrant boxes, and while traditionally they were generally bullet- or dome-shaped, in recent years flat-type indicator lights with flat or disc-shaped fronts and indicator lights integrated with transmitters have also been put to practical use. An invention relating to an indicator light that is attached integrally with a transmitter is described, for example, in Patent Document 3, and an invention relating to a transmitter equipped with a flat-type indicator light is described, for example, in Patent Document 4. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 7-85384 [Patent Document 2] Design Registration No. 1488967 [Patent Document 3] JP 2018-101135 A [Patent Document 4] JP 2018-120516 A Summary of the Invention [Problem to be solved by the invention]

[0006] Conventional bullet-shaped indicator lights protrude about 60 mm from the mounting surface, and because of this large protrusion, they have been replaced with flat-type indicator lights in recent years in order to avoid the possibility of them becoming an obstacle for passage or transportation, to reduce damage accidents, and to improve the appearance. There is also a demand to replace transmitters and indicator lights installed on building walls and doors for disaster prevention related equipment storage boxes with flat-type indicator light-attached transmitters. However, because the indicator light-equipped transmitter has a storage section for the lamp (LED), the housing is somewhat larger than that of the transmitter alone. Therefore, when replacing conventional indicator lights or transmitters installed on the walls of buildings or on the doors of disaster prevention equipment storage boxes with indicator light-equipped transmitters, the openings originally provided on the mounting surface for passing the wiring of the indicator light or transmitter and for fitting part of the transmitter body are small, so processing work to enlarge the opening on the mounting surface may be required when installing the indicator light-equipped transmitter. In addition, when attaching a transmitter with an indicator light to the door of a box for housing disaster prevention related equipment, it is possible to remove the original indicator light. However, simply removing the indicator light poses the problem that the opening provided for passing the wiring will be exposed, reducing the aesthetic appearance.

[0007] The present invention has been made with attention to the above-mentioned problems, and its object is to provide an adapter that allows an indicator light-equipped transmitter to be attached to a mounting surface without the need to process the opening to make it larger, even if the opening on the mounting surface for an existing indicator light or transmitter is small. Another object of the present invention is to provide a door for a disaster prevention equipment storage box that does not lose its aesthetic appearance even when the original indicator light or transmitter is replaced with a transmitter with an indicator light and the unnecessary indicator light and transmitter are removed. [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of an adapter for a transmitter with an indicator lamp to which the present invention is applied will be described with reference to the drawings. The transmitter adapter of this embodiment has a function of mounting a transmitter with an indicator light on the front side of the opening of the mounting surface. Hereinafter, the configuration of the adapter 20 will be described together with the configuration of the transmitter with an indicator light 100 to be mounted.

[0021] (First embodiment) Fig. 1 shows the adapter 20 of the first embodiment together with a transmitter with an indicator light 100 to which it is to be attached. The transmitter with an indicator light 100 shown in Fig. 1 is composed of a transmitter body 10 and an indicator light 15 that is integrated in a form that accommodates the transmitter body 10. The transmitter main body 10 has a function of transmitting a signal to a receiver informing of the occurrence of an abnormality such as a fire by firmly pressing a push button to turn on an internal switch. The transmitter main body 10 has a push button 11 located approximately in the center of the front surface, a housing section 12 containing a circuit board, and an attachment base body 13 provided at the front end of the housing section 12.

[0022] The mounting base body 13 has an opening 13B in the center through which the front of the push button 11 faces, and has a nearly flat front panel portion 13A which is oval-shaped when viewed from the front, with a step portion 13C formed so as to protrude rearward from the back surface of the front panel portion 13A, and partial male threads 13D1, 13D2 formed on the arc-shaped upper and lower surfaces of this step portion 13C.

[0023] The indicator light 15 comprises a pair of display units 51A, 51B located on both the left and right sides of the transmitter body 10, and a base unit 52 having a storage recess capable of storing the housing unit 12 of the transmitter body 10. An opening 53 is formed in the center of the bottom wall of the base unit 52, through which the housing unit 12 of the transmitter body 10 can be inserted, and the transmitter body 10 and the indicator light 15 are integrated with each other when the housing unit 12 and the stepped portion 13C of the transmitter body 10 are stored in the storage recess, as shown in Fig. 2. A recess is formed on the back of the front panel of the display units 51A and 51B of the indicator light 15, and a board on which a light emitting element is mounted can be housed in the recess. The indicator light 15 is made of transparent or translucent resin colored with red paint, and when the light emitting element is turned on, the display units 51A and 51B emit red light.

[0024] The adapter 20 is configured as a nut (annular nut) having an overall ring shape and a female thread portion 20A on its inner circumferential surface that can be screwed into the partial male threads 13D1, 13D2. The indicator light-equipped transmitter 100 is fixed to the mounting surface 30 by screwing the housing 12 of the transmitter main body 10 through the opening 53 of the base 52 of the indicator light 15 and into the opening of the mounting surface 30, and then screwing into the female threaded portion 20A of the adapter 20 fixed to the mounting surface 30. Furthermore, when the transmitter main body 10 is screwed into the adapter 20, the base 52 of the indicator light 15 is sandwiched between the mounting base body 13 and the mounting surface 30, so that the indicator light 15 is also fixed to the mounting surface 30 in a combined state with the transmitter main body 10.

[0025] The structure of the adapter 20 is shown in detail in Fig. 3. In Fig. 3, (A) is a front view of the adapter 20, and (B) is a vertical cross-sectional view taken along line AA in (A) to show the inside. As shown in Fig. 3(A), in this embodiment, two pot holes 20b into which screws can be inserted are formed on the front side of the adapter 20 at positions facing each other across the center, and as shown in Fig. 3(B), the adapter 20 is configured to be fixed by inserting two screws 21 into the pot holes 20b and screwing them into the mounting surface 30.

[0026] The two potentiometer holes 20b are formed to be point symmetrical, and after screw 21 is screwed into mounting surface 30, screw 21 is fitted into the larger hole of potentiometer hole 20b and the entire adapter 20 is rotated counterclockwise, whereby screw 21 moves into the smaller hole of potentiometer hole 20b, and adapter 20 is fixed to mounting surface 30 by screw 21. Also, as shown in Fig. 3(B), adapter 20 of this embodiment has a female thread portion 20A on its inner circumferential surface. When the partial male screws 13D1, 13D2 of the transmitter body 10 are screwed into this female screw portion 20A and the indicator light-equipped transmitter 100 is attached to a mounting surface by the adapter 20, part of the opening side of the daruma hole 20b is blocked by the flanges on the outer periphery of the front panels of the display units 51A, 51B of the indicator lights 15. The flanges on the outer periphery of the front panels of the display units 51A, 51B may be made to protrude a large amount so as to cover and hide the entire opening of the daruma hole 20b.

[0027] FIG. 4 shows a modification of the adapter 20 shown in FIG. In this modified example, instead of providing two bellows holes 20b on the front side of adapter 20, two screw holes 20c are provided on the rear side of adapter 20, and adapter 20 is fixed to the front side of mounting surface 30 by inserting screws 21 from the back side of mounting surface 30 and screwing them into screw holes 20c. In addition, since screw insertion holes for screwing a transmitter or an indicator light may already 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 by utilizing such screw insertion holes. Also, the adapter 20 may be configured not to have a screw hole on the rear side thereof, but to be attached from the rear side with a tapping screw.

[0028] According to the adapter of this embodiment configured as described above, the adapter can be fixed to the front surface of the mounting surface and the indicator light-equipped transmitter 100 can be attached to the mounting surface using this adapter, which has the advantage that the installation can be performed without having to enlarge the opening originally provided in the mounting surface. Furthermore, because the adapter 20 has the above-described configuration, in cases where the length of the flange portion on the outer periphery of the front panel of the indicator light 15 is short and it is not possible to cover the entirety of the daruma hole 20b, as shown in Figure 3(B), by eliminating the daruma hole 20b, it is possible to prevent part of the daruma hole 20b from being seen from the front.

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

[0030] Furthermore, for example, a retaining piece or inner flange protruding from the front end of the opening of the indicator light 15 so as to contact the side edge of the front surface of the transmitter body 10 from the front may be provided at the front end of the opening of the indicator light 15, so that when the male threaded portion of the indicator light 15 is screwed into the female threaded portion 20A of the adapter 20, a part of the transmitter body 10 is sandwiched between the adapter 20 and the male threaded portion, thereby automatically fixing the indicator light-equipped transmitter. Also, partial male threads 13D1, 13D2 may be provided on the outer periphery of the transmitter body 10, and a male threaded portion that screws into the female threaded portion 20A of the adapter 20 may also be provided on part of the outer periphery of the housing of the indicator light 15.

[0031] Second embodiment Fig. 5 shows an adapter 20 of a second embodiment. In Fig. 5, (A) is a front view of the adapter 20, (B) is a cross-sectional view taken along line AA in (A) to show the inside, and (C) is a cross-sectional view taken along line BB in (A) to show the inside. In the second embodiment of the adapter 20 shown in FIG. 5, instead of providing a female threaded portion 20A on the inner circumferential surface of the adapter 20 and screwing and fixing the transmitter 10, multiple locking pieces 22 (four in the figure) having claws 22a at the mid-height position as shown in FIG. 5(B) are provided along the circumferential direction on the inner circumferential wall of the adapter 20.

[0032] Fig. 6 shows an example of the configuration of a transmitter with an indicator lamp suitable for fixing by the adapter 20 shown in Fig. 5. As shown in Fig. 6, the partial male screws 13D1 and 13D2 are not provided on the transmitter body 10 of the transmitter in Fig. 6. However, the transmitter shown in Fig. 6 has a recess (groove) G at the boundary between the outer circumferential surface of the transmitter body 10 and the outer circumferential surface of the indicator lamp 15 integrally joined thereto. The adapter 20 shown in Fig. 5 is configured so that the transmitter is fixed to the adapter 20 by engaging the claws 22a of the four locking pieces 22 with the areas (four locations) surrounded by the dotted lines (circles) of this recess G.

[0033] The front side (upper side of (B)) of the adapter 20 is the free end of the locking piece 22, and when the indicator light-equipped transmitter is inserted from the front side, the outer peripheral surface of the indicator light 15 enters the inside of the adapter 20 while deforming the locking piece 22, and when the claw 22a matches the recess at the boundary between the outer peripheral surface of the transmitter body 10 and the outer peripheral surface of the indicator light 15, the elastic restoring force causes the locking piece 22 to move inward, and the claw 22a of the locking piece 22 engages with the recess G to function as a stopper. The number of locking pieces 22 is not limited to four, and it is sufficient to have one or more on each of the upper and lower sides. Adapter 20 is fixed to mounting surface 30 by screws 21 inserted into bolt holes 20c provided on the front side of adapter 20. Bolt holes 20c may be slotted holes similar to those shown in Fig. 3, or may be fixed by screws 21 from the back side of mounting surface 30 as shown in Fig. 5.

[0034] FIG. 7 shows a modification of the adapter 20 shown in FIG. In this modification, as shown in Fig. 7(C), a pair of screw insertion grooves 20d, each of which is a combination of a groove having a width allowing the insertion of the head of a screw 21 and a groove having a width allowing the insertion of the neck of a screw 21, are formed in parallel above and below along the tangential direction as shown in Fig. 7(A). These screw insertion grooves 20d are open at the bottom, and by aligning the openings on the bottom side of the screw insertion grooves 20d with two screws 21 that have been screwed into the edge of the opening 30A of the mounting surface 30 in advance, and then moving the adapter 20 downward, the screws 21 can be moved relatively to the back of the screw insertion grooves 20d, and the adapter 20 can be fixed to the front surface of the mounting surface 30.

[0035] 7(A) from the side, the bottom surface (step) of the wide groove into which the head of the screw 21 fits may be formed to have an inclination that increases from the opening at the lower end toward the top. This makes it easier to insert the screw 21 into the screw insertion groove 20d, and when the screw 21 is moved relatively to the bottom of the screw insertion groove 20d, the underside of the head of the screw 21 presses against the step of the screw insertion groove 20d, so that the adapter 20 will not easily move and come off the mounting surface 30 even if a force is applied to push the adapter 20 upward.

[0036] Third embodiment FIG. 8 shows an adapter according to a third embodiment. In the adapter of the third embodiment, instead of providing a female thread portion 20A on the inner surface of the adapter (annular nut) 20, a male thread portion 20B is provided on the outer surface of the adapter 20, and a retaining ring 23 is provided which has a female thread portion 23B that can be screwed into the male thread portion 20B and has a flange portion 23A on the inside of the front end face.

[0037] The flange portion 23A of the retaining ring 23 has an opening formed so that its inner edge is sized to contact the outer peripheral edge of the indicator light 15 of the indicator light-equipped transmitter when it is inserted so as to contact the front surface of the adapter 20. By clamping the edge of the indicator light 15 between the flange portion 23A and the adapter 20 using the retaining ring 23, the indicator light-equipped transmitter 100 can be fixed to the mounting surface 30 by the adapter 20. Adapter 20 is fixed to mounting surface 30 by screws 21 inserted into bolt holes 20c provided on the front side of adapter 20. Bolt holes 20c may be slotted holes similar to those shown in Fig. 3, or may be fixed by screws 21 from the back side of mounting surface 30 as shown in Fig. 5.

[0038] (Fourth embodiment) 9 to 11 show an embodiment of a door for a disaster prevention equipment storage box to which the present invention is applied, and an example of a cover for closing an opening for an indicator light provided in the door. Conventionally, as shown in Fig. 9(A), there is a disaster prevention equipment storage box 30 having a front door 31 provided with a conventional indicator light 33, a sound hole 32 for a speaker or bell, and a conventional transmitter 34. In addition, although not shown, there is a fire hydrant box stored inside the wall of a building, and the door provided on the front of the box is provided with an indicator light and a transmitter.

[0039] As described above, a door for a disaster prevention-related equipment storage box equipped with an indicator light and a transmitter has conventionally been provided with a bullet-shaped indicator light. Also, it has been common for the indicator light and the transmitter to be provided separately. Since the bullet-shaped indicator light protrudes significantly and becomes an obstacle when moving or transporting the box, there is a demand to replace it with a flat-shaped indicator light. Furthermore, as indicator light-equipped transmitters have become widespread, there are cases where an existing disaster prevention-related equipment storage box is desired to be replaced with an indicator light-equipped transmitter as shown in the above embodiment.

[0040] However, when the conventional indicator light 33 and conventional transmitter 34 provided on the conventional door 31 for a disaster prevention-related equipment storage box are removed and the indicator light-equipped transmitter 100 is installed, the opening 30A where the indicator light or transmitter was attached becomes exposed as shown in Fig. 9(B). 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 a disaster prevention-related equipment storage box is replaced with the indicator light-equipped transmitter 100 and the indicator light opening (30A) is closed with the cover 40 of this embodiment. It is preferable that the cover 40 is made of a resin or the like of the same color as the surrounding color, for example, the color of the disaster prevention related equipment storage box. For example, the disaster prevention related equipment storage box may change color from white to cream, and by preparing a cover 40 that matches the color of the disaster prevention related equipment storage box to be attached, it is possible to close the opening with a cover of the same color as the storage box to make it less noticeable.

[0041] As shown in FIG. 10, the cover 40 for closing the opening of this embodiment is composed of 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 in the center of one side of the cover body 41, and a disk-shaped annular nut 43 having a female screw portion 43a that can be screwed into the male screw body 42. The annular nut 43 is provided with a plurality of screw insertion holes 43b on the outer edge. The screw insertion hole 43b has a large diameter portion larger than the head of the screw to be 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. It is preferable that the annular nut 43 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 relatively large-diameter disk-shaped cover body 41 and a disk-shaped annular nut 43, each of which includes a male screw body 42 and a female screw portion 43a that can be screwed together, so that if the opening formed in the door 31 for storing disaster-related equipment 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), and if the opening is small, the opening can be closed as shown in Fig. 11(B). The cover for closing the opening of this embodiment can be used with doors for storing disaster-related equipment boxes with openings of different sizes.

[0043] In addition, when the panel of the door 31 cannot be sandwiched, the opening can be closed by inserting a screw into the screw insertion hole 43b provided on the outer edge of the annular nut 43 to fix the annular nut 43 to the mounting surface, and screwing the cover body 41 to the annular nut. Even when the panel of the door 31 can be sandwiched between the cover body 41 and the annular nut 43, if the opening is large, the opening can be closed by inserting a screw into the screw insertion hole 43b to fix the annular nut 43 to the back surface of the panel, and screwing the cover body 41 to the annular nut. This makes it possible to prevent the cover body 41 and the annular nut 43 in the screwed state from shifting while still screwed together, thereby exposing a part of the opening.

[0044] Although the present invention has been described above based on the embodiment, the present invention is not limited to the above embodiment. For example, in FIG. 10, the cover body 41 of the cover 40 for closing the opening is shown as a circle, 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. The ring 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, and may be composed of, for example, a small-diameter boss having a screw insertion hole 43b and a plurality of arms extending radially from the boss. Furthermore, if the ring nut 43 has a gripping portion as shown in FIG. 3 or FIG. 4 on the outer periphery, it is easy to install. In addition, in the first to third embodiments, the left and right light-emitting display portions 51A, 51B of the indicator light 15 that is combined with the transmitter main body 10 are shown to be bow-shaped, but shapes such as a crescent shape, a semi-cylindrical shape, a triangle shape, or a ring shape may also be adopted.

[0045] In addition, in the above embodiment, the mounting base body 13 of the transmitter main body 10 is shown to be oval in front view, but the shape of the mounting base body 13 is not limited to oval, and may be other shapes such as circular, elliptical, rectangular, etc. Furthermore, in the above embodiment, the present invention has been described as being applied to an apparatus that combines a fire transmitter that constitutes a fire alarm system and an indicator light that can be combined with the transmitter, but the present invention is not limited to fire transmitters and can be widely used in transmitters for train emergency alerts that are installed on station platforms and railroad crossings. Furthermore, the transmitter adapter with indicator light and blocking cover of the above embodiment are not limited to doors for disaster prevention equipment storage boxes, but can also be applied to transmitters and indicator lights that are attached separately to switch boxes embedded in wall surfaces (panels), etc. [Explanation of symbols]
