The connection terminal 212 has a box-shaped portion 212a and a blade-shaped portion 212b extending from the box-shaped portion 212a. The box-shaped portion 212a is a wire connection terminal, and the tip of the sensor line Q is inserted into the insertion hole 212a1 provided in the box-shaped portion 212a. The blade-like portion 212b is a connection terminal, and is engaged with a claw piece (connection terminal) provided on the sensor body 220 that actually detects fire to hold the sensor body 220. .

  The main body 211 of the sensor base 210 is provided with a pair of first screw holes 213 and a pair of second screw holes 214 penetrating in the thickness direction (vertical direction) of the sensor base 210. The first screw hole 213 and the second screw hole 214 are provided as screw holes for the fixing screw N1 (screw holes through which the shaft portion of the fixing screw N1 can be inserted). The one screw hole 213 and the second screw hole 214 are used as screw holes for the attachment screw N2 (screw holes through which the shaft portion of the attachment screw N2 can be inserted). Therefore, the first screw hole 213 and the second screw hole 214 provided as the screw holes for the fixing screw N1 can be used as the screw holes for the mounting screw N2, and have the same shape as the fixing screw N1.

Arranged outside. The center of the circumference where the first screw hole 213 is arranged, the center of the circumference where the second screw hole 214 is arranged, and the center of the sensor base 210 are the same. Accordingly, the distance from the center of the sensor base 210 to the first screw hole 213 is shorter than the distance from the center of the sensor base 210 to the second screw hole 214.
In addition, in the substantially central portion of the main body 211 of the sensor base 210, a lead-in hole 215 for drawing the tip of the sensor line Q from the upper surface side to the lower surface side of the sensor base 210 is provided. It is provided penetrating in the direction (vertical direction).

  3-6 is a figure which shows an example of the information transmission adapter which concerns on embodiment of this invention. Specifically, FIG. 3 is a view showing a state in which the base member 110 and the case member 120 are combined, and is a view seen from the lower surface side. FIG. 4 is a view showing a state where the base member 110 and the case member 120 are separated, and is a perspective view seen from the upper surface side. FIG. 5 is a view showing a state where the base member 110 and the case member 120 are separated, and is a perspective view seen from the lower surface side. FIG. 6 is a diagram showing a state where the base member 110 and the case member 120 are separated, and is an exploded perspective view seen from the lower surface side. In FIG. 3, the sensor base 210 and the mounting screw N2 are indicated by phantom lines (two-dot chain lines). In FIG. 6, illustration of a part of the sensor base 210 (such as the connection terminal 212) is omitted.

As shown in FIGS. 3 and 6, for example, the information transmission adapter 100 includes a substantially disk-shaped base member 110 having an outer diameter larger than the outer diameter of the sensor base 210, and a case member that houses the base member 110 therein. 120 and an information transmission module 160 attached to the base member 110.
The outer diameter of the base member 110 may be the same as the outer diameter of the sensor base 210, or may be smaller than the outer diameter of the sensor base 210.

The base member 110 is made of a resin (may be a flame retardant resin or may not be a flame retardant resin). For example, as illustrated in FIG. 6, the base member 110 includes a main body 111 configured to be able to store the information transmission module 160, and a lid 112 that closes an opening surface of the main body 111 (the lower surface in the present embodiment). , And is configured.
Further, as shown in FIGS. 4 and 5, for example, an opening 113 for avoiding interference with the sensor line Q penetrates the base member 110 in the thickness direction (vertical direction) of the base member 110. Is provided. The opening 113 is disposed at a position facing the lead-in hole 215 of the sensor base 210 when the fire sensor 200 is attached to the information transmission adapter 100.

For example, as illustrated in FIG. 6, the case member 120 includes an upper plate portion 130 disposed on the upper surface side of the base member 110, a lower plate portion 140 disposed on the lower surface side of the base member 110, and an upper plate portion 130. And a connecting portion 150 that connects the lower plate portion 140 to each other.
The base member 110 can be attached to and detached from the case member 120 by sliding along a plane perpendicular to the vertical direction between the upper plate portion 130 and the lower plate portion 140 of the case member 120. . In the following description, the advancing direction side of the base member 110 when attaching the base member 110 to the case member 120 is the front side, and the advancing direction side of the base member 110 when removing the base member 110 from the case member 120 is the rear side. And In addition, a direction orthogonal to both the vertical direction and the front-rear direction is defined as the left-right direction.

The upper plate part 130 is, for example, a substantially circular plate member having an outer diameter substantially the same as the outer diameter of the base member 110, and is formed by pressing a single metal plate by pressing or the like.
The lower plate portion 140 is, for example, a substantially circular plate member having an outer diameter that is the same as the outer diameter of the upper plate portion 130, and is formed by pressing one metal plate by pressing or the like.
In the present embodiment, the upper plate portion 130 and the lower plate portion 140 are made of metal from the viewpoint of improving the strength, but the upper plate portion 130 and the lower plate portion 140 are not limited to metal. From the standpoint of preventing the radio wave from being cut off and the transmission efficiency of the radio wave from being slowed, the upper plate portion 130 may be made of metal and the lower plate portion 140 may be made of resin, Both side plate portions 140 may be made of resin.

For example, as shown in FIGS. 4 and 5, the connecting portion 150 includes a front connecting plate 151 that connects the front ends of the upper plate portion 130 and the lower plate portion 140, and the left ends of the upper plate portion 130 and the lower plate portion 140. It consists of the left side connection plate 152 which connects each other, and the right side connection plate 153 which connects the right ends of the upper plate part 130 and the lower plate part 140. The connection plates 151 to 153 may be made of metal or resin.
The connecting portion 150 connects the upper plate portion 130 and the lower plate portion 140 in a state where the center of the upper plate portion 130 and the center of the lower plate portion 140 are aligned (opposed). Therefore, the center of the case member 120 coincides with the center of the upper plate portion 130 and the center of the lower plate portion 140.
Further, when the base member 110 and the case member 120 are combined, the center of the base member 110 and the center of the case member 120 coincide with each other.

  For example, as shown in FIG. 5, the lower plate portion 140 is provided with a pair of mounting screw holes 141 and a pair of insertion holes 142 penetrating in the thickness direction (vertical direction) of the case member 120. Yes. The attachment screw hole 141 can be screwed with an attachment screw N2 for attaching the fire detector 200 to the case member 120. In other words, the mounting screw hole 141 is a screw receiver to which the mounting screw N2 is screwed, and the mounting screw hole 141 is subjected to female thread processing such as nut embedding. Moreover, the shaft part and head part of the fixing screw N1 for fixing the case member 120 to the to-be-attached part P can be passed through the insertion hole 142.

The insertion hole 142 is formed in an arc shape extending along the circumferential direction concentric with the lower plate portion 140 having a substantially circular outer shape. That is, the insertion hole 142 is disposed on a circumference concentric with the case member 120.
The mounting screw hole 141 is disposed on an extension line of the arcuate insertion hole 142. That is, the mounting screw hole 141 and the insertion hole 142 are arranged on the same circumference, and the center of the circumference where the mounting screw hole 141 and the insertion hole 142 are arranged, and the center of the case member 120 Are the same. Therefore, the distance from the center of the case member 120 to the mounting screw hole 141 is the same as the distance from the center of the case member 120 to the insertion hole 142.

For example, as shown in FIG. 4, the upper plate portion 130 is provided with a pair of fixing screw holes 131 penetrating in the thickness direction (vertical direction) of the case member 120. The shaft portion of the fixing screw N1 for fixing the case member 120 to the attachment portion P can pass through the fixing screw hole 131, but the head portion of the fixing screw N1 cannot pass.
The fixing screw hole 131 is formed in an arc shape extending along a circumferential direction concentric with the upper plate portion 130 having a substantially outer shape. That is, the fixing screw hole 131 is arranged on a circumference concentric with the case member 120.
The fixing screw hole 131 has substantially the same shape as the insertion hole 142 of the lower plate part 140, and in a state where the upper plate part 130 and the lower plate part 140 are connected by the connection part 150, the insertion hole 142. Is facing. That is, the diameter of the circumference in which the fixing screw hole 131 of the upper plate portion 130 is disposed is the same as the diameter of the circumference in which the mounting screw hole 141 and the insertion hole 142 of the lower plate portion 140 are disposed. is there.

Further, the diameter of the circumference in which the mounting screw hole 141 and the insertion hole 142 of the lower plate part 140 are arranged is the same as the diameter of the circumference in which the first screw hole 213 of the sensor base 210 is arranged. is there. Therefore, the mounting screw hole 141 can receive the shaft portion of the mounting screw N2 that has passed through the first screw hole 213 of the sensor base 210. That is, when the fire detector 200 is screwed to the case member 120, the screw base for the mounting screw N2 on the detector base 210 side (screw hole through which the shaft portion of the mounting screw N2 can be inserted) is the first. Screw holes 213 can also be used.
In the present embodiment, of the first screw hole 213 and the second screw hole 214 of the sensor base 210, the first screw hole 213 is used as a screw hole for the mounting screw N2.

  Further, the mounting screw hole 141 is disposed on the circumference concentric with the case member 120, and the first screw hole 213 is disposed on the circumference concentric with the sensor base 210. Therefore, when the fire detector 200 is attached to the case member 120 (screwed state), the center of the case member 120 and the center of the detector base 210 coincide with each other.

Further, as shown in FIG. 4 for example, the upper plate portion 130 is provided with an opening 132 for avoiding interference with the sensor line Q, penetrating in the thickness direction (vertical direction) of the case member 120. ing. The opening 132 is disposed at a position facing the lead-in hole 215 of the sensor base 210 in a state where the fire sensor 200 is attached to the case member 120.
Similarly, an opening 143 for avoiding interference with the sensor line Q passes through the lower plate portion 140 in the thickness direction (vertical direction) of the case member 120, for example, as shown in FIG. Is provided. The opening 143 is disposed at a position facing the lead-in hole 215 of the sensor base 210 in a state where the fire sensor 200 is attached to the case member 120.

  7 and 8 are cross-sectional perspective views of the information transmission adapter 100 and the sensor base 210 attached to the information transmission adapter 100, and FIG. 7 is a cross-sectional view taken along the center line passing through the fixing screw hole 131. FIG. 8 is a cross-sectional view taken along the center line passing through the mounting screw hole 141.

  For example, as shown in FIG. 7, the head of the fixing screw N <b> 1 protrudes downward from the lower surface of the upper plate portion 130. On the other hand, as shown in FIGS. 4 and 7, for example, an upper guide groove 114 that is recessed downward is provided on the upper surface of the base member 110 along the front-rear direction (that is, the sliding direction of the base member 110). In the state where the information transmission adapter 100 is fixed to the attached portion P, the head of the fixing screw N1 is arranged in the upper guide groove 114.

Thus, in this embodiment, since the guide structure for fixing the base member 110 to and from the case member 120 is guided by the fixing screw N1 and the upper guide groove 114, the base member The base member 110 can be smoothly attached to an appropriate position simply by sliding the 110 with respect to the case member 120.
In addition, for example, it is possible to provide a protrusion on the lower surface of the upper plate portion 130 of the case member 120 and use the protrusion as a guide. However, in the present embodiment, the fixing screw N1 can be used as a guide. There is no need to provide such a projection on the plate portion 130.
Further, the upper guide groove 114 can avoid contact with the fixing screw N1. Accordingly, the distance between the base member 110 and the upper plate portion 130 is made larger than the height (length in the vertical direction) of the head of the fixing screw N1, or the thickness of the upper plate portion 130 is set to the head of the fixing screw N1. The information transmitting adapter 100 can be thinned because it is not necessary to increase the size so that the portion is buried in the upper plate portion 130.

  For example, as shown in FIG. 8, the tip of the shaft portion of the mounting screw N <b> 2 protrudes upward from the upper surface of the lower plate portion 140. On the other hand, as shown in FIGS. 5 and 8, for example, a lower guide groove 115 that is recessed upward is provided on the lower surface of the base member 110 along the front-rear direction (that is, the sliding movement direction of the base member 110). In the state where the information transmission adapter 100 is fixed to the mounted portion P, the tip of the shaft portion of the mounting screw N2 is arranged in the lower guide groove 115.

As described above, in the present embodiment, the guide structure including the mounting screw N2 and the lower guide groove 115 is used as a guide structure for guiding the attachment / detachment of the base member 110 to / from the case member 120. By simply sliding the member 110 with respect to the case member 120, the base member 110 can be smoothly attached to an appropriate position.
Further, for example, it is possible to provide a protrusion on the upper surface of the lower plate portion 140 of the case member 120 and use the protrusion as a guide, but in the present embodiment, the mounting screw N2 can be used as a guide. There is no need to provide such protrusions on the lower plate portion 140.
Further, the lower guide groove 115 can avoid contact with the mounting screw N2. Therefore, the interval between the base member 110 and the lower plate portion 140 is made larger than the protruding height of the shaft portion of the mounting screw N2, or the thickness of the lower plate portion 140 is reduced by the entire shaft portion of the mounting screw N2. Since it is not necessary to make it large enough to be embedded in the side plate portion 140, the information transmission adapter 100 can be thinned.

In this embodiment, as a guide structure for guiding attachment / detachment of the base member 110 to / from the case member 120, a guide structure including a fixing screw N1 and an upper guide groove 114, an attachment screw N2, and a lower guide groove 115 are provided. Two types of guide structures are provided, but only one of them may be provided.
Further, the guide structure for guiding the attachment / detachment of the base member 110 to / from the case member 120 is limited to the guide structure including the fixing screw N1 and the upper guide groove 114, and the guide structure including the mounting screw N2 and the lower guide groove 115. It can be changed as appropriate.

For example, as shown in FIGS. 4 and 5, the front side connecting plate 151 of the case member 120 is provided with a pair of fitting hole portions 154 penetrating in the front-rear direction (that is, the sliding movement direction of the base member 110). ing. On the other hand, a pair of elastically deformable insertion portions 116 project from the front end of the base member 110. When the base member 110 and the case member 120 are combined, the insertion portion 116 is a fitting hole portion. 154 is configured to fit.
A locking claw 116a facing outward is provided at the distal end of the insertion part 116 so that the state where the insertion part 116 is fitted in the fitting hole 154 can be maintained by the locking claw 116a. It has become. Further, by pulling the base member 110 attached to the case member 120 backward with a predetermined force or more, the locking claw 116a is pushed against the wall surface that forms (defines) the fitting hole 154, The pair of insertion portions 116 are elastically deformed so that the tip portions of the insertion portions 116 approach each other. Thereby, since the state in which the insertion part 116 was fitted in the fitting hole part 154 can be cancelled | released, the base member 110 can be removed from the case member 120. FIG.

As described above, in the present embodiment, as the locking structure for detachably locking the base member 110 to the case member 120, the locking structure including the fitting hole portion 154 and the insertion portion 116 is provided. Therefore, for example, even when subjected to shaking such as an earthquake, the combined state of the base member 110 and the case member 120 can be stably maintained. Further, since the base member 110 can be detached from the case member 120 simply by pulling the base member 110 with a predetermined force or more, the base member 110 can be easily attached and detached.
The locking structure for detachably locking the base member 110 to the case member 120 is not limited to the locking structure including the fitting hole portion 154 and the insertion portion 116, and can be changed as appropriate.

For example, as shown in FIG. 4, a plurality of (three in this embodiment) projections 133 are provided at appropriate positions on the upper surface of the upper plate portion 130 of the case member 120, and the information transmission adapter 100 is In a state of being fixed to the attached portion P, the contact area between the information transmission adapter 100 and the attached portion P is configured to be as small as possible.
Thus, in this embodiment, since the absorption structure for absorbing the unevenness on the surface of the attached part P has an absorption structure composed of a plurality of protrusions 133, the surface of the attached part P has unevenness. Even in some cases, it is difficult to be affected by the unevenness, and the information transmission adapter 100 can be stably fixed without rattling to the attached portion P.
In addition, the absorption structure for absorbing the unevenness | corrugation of the surface of the to-be-attached part P is not limited to the absorption structure which consists of several protrusion 133, It can change suitably, For example, it affixed on the upper surface of the upper side plate part 130. An absorption structure made of an elastically deformable mat or the like may be used.

  Moreover, it is preferable that the base member 110 is provided with a knob portion or the like that puts a finger on the base member 110 when the base member 110 is removed from the case member 120 (when the base member 110 is pulled with a predetermined force or more).

The information transmission module 160 is a module that wirelessly transmits device-specific identification information for position detection. For example, as shown in FIG. 6, the information transmission module 160 includes an information transmission terminal 161 including a circuit board, a transmission circuit unit, an antenna unit, and the like, and a power source 162 that supplies power to the information transmission terminal 161. Yes.
The power source 162 is composed of one or a plurality of batteries. For example, as shown in FIG. 6, a plurality of storage chambers 111 a for detachably storing one battery are provided inside the main body 111 of the base member 110. Since the plurality of storage rooms 111a are connected in parallel, the power supply 162 can supply power to the information transmission terminal 161 even if all the storage rooms 111a are not filled. In the case of this embodiment, since the base member 110 has six storage chambers 111a, a maximum of six batteries can be mounted on the information transmission adapter 100.

In the present embodiment, the storage chamber 111a is configured to accommodate a button-type battery, but is not limited thereto, and the storage chamber 111a can accommodate, for example, a cylindrical battery (cylindrical lithium battery). It may be configured as follows.
Further, the number of the storage chambers 111a is not limited to six, and can be changed as appropriate. For example, the number may be one.

Here, an example of the installation method of the information transmission adapter 100 of this embodiment is demonstrated.
The information transmission adapter 100 can be installed in the vicinity of the newly installed fire detector 200 or in the vicinity of the existing fire detector 200. Specifically, the information transmission adapter 100 is, for example, a new fire detector 200 and a cover to which the fire detector 200 is attached when the fire receiver is stopped without being turned on during construction. It can be installed between the mounting portion P and the mounting portion P. Furthermore, the information transmission adapter 100 is used when the fire detector maintenance mode is set, for example, during maintenance or inspection, or when the operator intentionally sets the target fire detector without disturbing the function of the self-reporting equipment. When removing, it can be installed between the existing fire detector 200 and the attached portion P to which the fire detector 200 is attached. Here, the installation method in the vicinity of the existing fire detector 200 will be described.

First, the sensor body 220 is removed from the sensor base 210 (first step).
Next, the fixing screw N1 is removed to create a predetermined gap between the sensor base 210 and the attached portion P (second step).

  Next, the case member 120 is inserted between the sensor base 210 and the attached portion P (third step). In the present embodiment, the opening 132 of the upper plate portion 130 is formed with a communication opening 132a that communicates with the outside, for example, as shown in FIG. Further, for example, as shown in FIG. 5, a communication opening 143 a that communicates with the outside is formed in the opening 143 of the lower plate part 140. These communication openings 132a and 143a are provided to avoid interference with the sensor line Q when the case member 120 is inserted between the sensor base 210 and the attached portion P. That is, when the case member 120 is inserted between the sensor base 210 and the attached portion P, the case member 120 is properly inserted without being obstructed by the sensor line Q by being inserted from the communication openings 132a and 143a. You can enter the position. Therefore, the case member 120 is disposed between the sensor base 210 and the mounted portion P to which the sensor base 210 is attached without removing the sensor line Q from the sensor base 210. Can do.

Next, the fixing member N1 is used to fix the case member 120 to the attachment portion P by screwing (fourth step). In the present embodiment, the lower plate part 140 has an insertion hole 142 at a position facing the fixing screw hole 131 of the upper plate part 130. Therefore, when the fixing screw N1 is inserted into the fixing screw hole 131 or when the fixing screw N1 is tightened with a screwdriver or the like, the work can be performed from below the case member 120 (lower plate portion 140) via the insertion hole 142. Therefore, work efficiency is improved.
In this embodiment, the diameter of the circumference where the fixing screw hole 131 of the case member 120 is arranged is the same as the diameter of the circumference where the first screw hole 213 of the sensor base 210 is arranged. is there. Therefore, since the screw hole on the attached portion P side used when attaching the sensor base 210 to the attached portion P can be used also when fixing the case member 120 to the attached portion P, the information transmission adapter When installing 100, it is not necessary to newly provide a screw hole in the attached portion P. Further, when the fire detector 200 is attached to the attachment portion P, a screw having a screw length suitable for the shape and material of the attachment portion P or the surrounding environment is selected and used as the fixing screw N1. Since the thickness T (see FIG. 7) of the insertion portion of the fixing screw hole 131 of the case member 120 is equal to or less than the thickness of the insertion portion of the first screw hole 213 of the sensor base 210, the case member 120 is attached. When fixing to the part P, by using the fixing screw N1 selected when the fire detector 200 is attached to the attachment part P, the case member 120 is attached to the case member 120 in the same situation as when the sensor base 210 is attached. The mounting portion P can be fixed with screws. Further, when fixing the case member 120 to the attached portion P, the fixing screw N1 selected when attaching the fire detector 200 to the attached portion P can be used. The screw to be prepared is only the mounting screw N2.

  Next, the sensor base 210 is screwed and attached to the case member 120 using the mounting screw N2 (fifth step). In the present embodiment, the diameter of the circumference in which the mounting screw hole 141 of the case member 120 is arranged is the same as the diameter of the circumference in which the first screw hole 213 of the sensor base 210 is arranged. Therefore, the screw hole (first screw hole 213) on the sensor base 210 side used when the sensor base 210 is attached to the attachment portion P is also used when the sensor base 210 is attached to the case member 120. Therefore, the sensor base 210 attached to the attached portion P with the fixing screw N1 can be used as it is. That is, when the information transmission adapter 100 is installed, there is no need to newly install a screw hole in the sensor base 210 or replace it with the sensor base 210 dedicated to the information transmission adapter 100.

Next, the base member 110 on which the information transmission module 160 is mounted is attached to the case member 120 to configure the information transmission adapter 100 (sixth step). When the base member 110 is attached to the case member 120, the base member 110 is slid and moved between the upper plate portion 130 and the lower plate portion 140 of the case member 120 along a plane perpendicular to the vertical direction. In the present embodiment, a communication opening 113a that communicates with the outside is formed in the opening 113 of the base member 110, for example, as shown in FIGS. The communication opening 113a is connected to the sensor line Q when the base member 110 is inserted between the upper plate portion 130 and the lower plate portion 140 (that is, between the mounted portion P and the sensor base 210). It is provided to avoid interference. That is, when the base member 110 is attached to the case member 120, the base member 110 can be moved to an appropriate position without being obstructed by the sensor line Q by being inserted from the communication opening 113a. Therefore, the base member 110 is disposed between the attached portion P and the sensor base 210 attached to the attached portion P without removing the sensor line Q from the sensor base 210. Can do.
Finally, the sensor body 220 is attached to the sensor base 210 (seventh step).

  Thus, the information transmission adapter 100 inserts the case member 120 between the sensor base 210 and the attached portion P, and then the base member to which the information transmission module 160 is attached to the case member 120. It can be installed on the fire detector 200 (in the vicinity of the fire detector 200) simply by attaching (sliding) 110. That is, the information transmission adapter 100 of this embodiment can be installed in the vicinity of the fire detector 200 without removing the sensor line Q from the sensor base 210.

Moreover, the information transmission adapter 100 of this embodiment can remove only the base member 110 in the state installed in the vicinity of the fire detector 200. Therefore, since only the base member 110 to which the information transmission module 160 is attached can be removed without removing the fixing screw N1, the mounting screw N2, and the sensor line Q, the fire monitoring by the fire sensor 200 is interrupted. The components can be exchanged without any problems.
Furthermore, the base member 110 can be removed from the case member 120 by simply pulling it with a predetermined force or more. Therefore, the base member 110 to which the information transmission module 160 is attached can be easily removed.

  Here, in the information transmission adapter 100 installed in the vicinity of the fire detector 200, replacement of a component, addition of a component, addition of a function (for example, realizable by exchanging an information transmission terminal), etc. To do this, it is necessary to remove at least a part of the information transmission adapter 100. The information transmission adapter 100 of this embodiment can remove only the base member 110 by pulling with a predetermined force or more without removing the fixing screw N1, the mounting screw N2, or the sensor line Q. That is, since the base member 110 can be easily removed without interrupting the fire monitoring by the fire detector, it is possible to easily replace components, add components, add functions, and the like. Excellent maintainability and workability during renewal.

  Further, the fire detector 200 needs to be securely attached to a ceiling or a fixture (attachment) that can be regarded as a ceiling. In that respect, since the information transmission adapter 100 of the present embodiment fixes the case member 120 to the attached portion P (fixing device that can be regarded as a ceiling or a ceiling) using screws, the case member 120 is a fixing device that can be regarded as a ceiling. It can be said that there is. And since the fire detector 200 is attached to the case member 120 using a screw, the fire detector 200 can be reliably attached. That is, the information transmission adapter 100 satisfies the installation conditions equivalent to the attached portion P to which the fire detector 200 can be attached, and can attach the fire detector 200. Furthermore, the information transmission adapter 100 of the present embodiment is not interposed between the sensor base 210 and the sensor body 220. Therefore, the information transmission adapter 100 of this embodiment can be installed in the vicinity of the fire detector 200 without affecting the function / performance of the fire detector 200.

  The information transmission adapter 100 of the present embodiment described above is fixed to the attached portion P, the case member 120 to which the fire detector 200 is attached, the substantially disk-shaped base member 110 housed in the case member 120, An information transmission module 160 attached to the base member 110, and the case member 120 has a fixing screw hole 131 into which a shaft portion of a fixing screw N1 for fixing the case member 120 to the attached portion P can be inserted. An upper plate portion 130 having a lower plate portion 140 having an attachment screw hole 141 that can be screwed together with an attachment screw N2 for attaching the fire detector 200 to the case member 120. The case member 120 is attached and detached by sliding between the upper plate portion 130 and the lower plate portion 140.

Therefore, it is possible to replace the constituent elements without interrupting the fire monitoring by the fire detector 200.
Further, it can be fixed (installed) in the vicinity of the fire detector 200 without affecting the function / performance of the fire detector 200.
In addition, since the fixing screw hole 131 and the mounting screw hole 141 are provided in the case member 120, the information transmission adapter is more effective than the case where the fixing screw hole or the mounting screw hole is provided in the base member 110. The diameter of 100 can be reduced. The smaller the diameter of the information transmission adapter 100, the smaller the contact area between the information transmission adapter 100 and the mounted portion P. Therefore, the smaller the diameter of the information transmission adapter 100, the more uneven the surface of the mounted portion P. It becomes difficult to be affected by the unevenness, and the information transmission adapter 100 can be stably fixed without rattling the attached portion P.
Note that the fixing screw hole 131 may not be a long hole (arc-shaped hole), but may be a short hole (for example, a hole having a major axis and a minor axis substantially the same).

Further, in the information transmission adapter 100 of the present embodiment, the fixing screw hole 131 and the mounting screw hole 141 are arranged on the same circumference, and the circumference is concentric with the base member 110. It is configurable.
With this configuration, when the information transmission adapter 100 is fixed (installed), it is not necessary to newly provide a screw hole in the attached portion P or the fire detector 200.

Further, in the information transmission adapter 100 of the present embodiment, the lower plate portion 140 can be configured to have an insertion hole 142 through which the head of the fixing screw N1 can pass in a portion facing the fixing screw hole 131. .
By configuring in this way, the operation of fixing the case member 120 to the attached portion P can be performed from below the case member 120 through the insertion hole 142, so that the work efficiency is improved.

Further, in the information transmission adapter 100 of the present embodiment, the base member 110 has a first groove portion (upper guide) for avoiding contact with the fixing screw N1 whose shaft portion is inserted into the fixing screw hole 131 on the upper surface. And a second groove portion (lower guide groove 115) for avoiding contact with the mounting screw N2 screwed into the mounting screw hole 141 on the lower surface.
With this configuration, the information transmission adapter 100 can be thinned.

Moreover, in the information transmission adapter 100 of this embodiment, the information transmission module 160 has the information transmission terminal 161 and the power supply 162 which supplies electric power to the said information transmission terminal 161, and the power supply 162 is one or several. It can be comprised from a battery and the electric power from the said battery can be supplied to the information transmission terminal 161. FIG.
With this configuration, the battery (component) can be replaced without interrupting the fire monitoring by the fire detector 200.

<Modification 1>
For example, as shown in FIGS. 9 and 10, the information transmission adapter 100 may include an attachment member 170 instead of the case member 120.
FIG. 9 is a diagram showing a state where the base member 110 and the attachment member 170 are separated, and is an exploded perspective view seen from the lower surface side. FIG. 10 is a view showing a state where the base member 110 and the attachment member 170 are separated, and is a perspective view seen from the upper surface side. In FIG. 9, illustration of a part of the sensor base 210 (such as the connection terminal 212) is omitted. Further, in FIG. 10, the sensor base 210 is shown only by the outer shape.

For example, as shown in FIG. 9, the attachment member 170 includes an upper plate portion 130 disposed on the upper surface side of the base member 110 and a pair of projecting portions 180 extending from the upper plate portion 130. The
The base member 110 slides along a plane perpendicular to the vertical direction between the upper plate portion 130 of the attachment member 170 and the sensor base 210 attached to the attachment member 170, so that the upper plate portion 130 The space S between the sensor base 210 and the sensor base 210 can be attached and detached. In the following description, the advancing direction side of the base member 110 when the base member 110 is attached to the space S is a front side, and the advancing direction side of the base member 110 when the base member 110 is removed from the space S is a rear side. . In addition, a direction orthogonal to both the vertical direction and the front-rear direction is defined as the left-right direction.

  The attachment member 170 is formed, for example, by molding a single metal plate by pressing or the like. In addition, the attachment member 170 is not limited to metal, At least one part may be resin.

The projecting portion 180 has a substantially L shape with the tip portion facing inward. The base end of one protrusion 180 and the base end of the other protrusion 180 are arranged on the same straight line passing through the center of the upper plate part 130 (that is, the center of the attachment member 170). In the present embodiment, both tip portions of one tip portion 180 and the other projecting portion 180 face inward, but the orientation of the tip portion can be changed as appropriate, for example, both tip portions are outside. Or one tip may face the inside and the other tip may face the outside.
The protruding height (vertical length) of the protruding portion 180 is the thickness of the space S between the upper plate portion 130 and the sensor base 210. Therefore, the protruding height of the protruding portion 180 is slightly larger than the thickness (length in the vertical direction) of the base member 110.

For example, as shown in FIG. 9, an attachment screw hole 141 that can be screwed with an attachment screw N <b> 2 for attaching the fire detector 200 to the attachment member 170 is provided at the distal end portion of the protrusion 180. It is provided penetrating in the (vertical direction).
The center of the circumference where the mounting screw hole 141 is arranged is the same as the center of the attachment member 170. That is, the mounting screw hole 141 is arranged on a circumference concentric with the attachment member 170.
Moreover, the diameter of the circumference where the fixing screw hole 131 of the upper plate portion 130 is arranged is the same as the diameter of the circumference where the mounting screw hole 141 of the protruding portion 180 is arranged. That is, the circumference diameter where the mounting screw hole 141 is arranged is the same as the circumference diameter where the first screw hole 213 of the sensor base 210 is arranged.

In the present modification, for example, as shown in FIG. 9, a plurality of engagement protrusions 112 b are provided on the lid portion 112 of the base member 110 and a plurality of engagements are made on the main body portion 111 of the base member 110. A receiving part 111b is provided.
The engagement protrusion 112b has a claw at the tip, and the claw can maintain a state engaged with the engagement receiving portion 111b.
Further, the engaging protrusion 112b can be elastically deformed. Therefore, by pulling the lid portion 112 attached to the main body 111 with a predetermined force or more, the engaging projection 112b is elastically deformed by the claw of the engaging projection 112b being pushed by the engagement receiving portion 111b. To do. Thereby, since engagement with the engagement receiving part 111b and the engagement protrusion 112b can be cancelled | released, the cover part 112 can be removed from the main-body part 111. FIG.
The lid portion 112 may not be removable from the main body portion 111. Specifically, the lid portion 112 may be configured not to be detached from the main body portion 111 simply by pulling the lid portion 112 with a predetermined force or more, for example, by attaching the lid portion 112 to the main body portion 111 in a fitted state.

Here, an example of the installation method of the information transmission adapter 100 of this modification is demonstrated.
The information transmission adapter 100 of this modification can be installed in the vicinity of the newly installed fire sensor 200 or in the vicinity of the existing fire sensor 200, similarly to the information transmission adapter 100 of the above embodiment. Here, the installation method in the vicinity of the existing fire detector 200 will be described.

First, the sensor body 220 is removed from the sensor base 210 (first step).
Next, the fixing screw N1 is removed to create a predetermined gap between the sensor base 210 and the attached portion P (second step).

Next, the attachment member 170 is inserted between the sensor base 210 and the attached portion P (third step).
In the present modification, the opening 132 of the upper plate portion 130 is formed with a communication opening 132a that communicates with the outside, as shown in FIG. 9, for example. The communication opening 132a is provided in order to avoid interference with the sensor line Q when the attachment member 170 is inserted between the sensor base 210 and the attached portion P. That is, when the attachment member 170 is inserted between the sensor base 210 and the attached portion P, the attachment member 170 is moved to the proper position without being obstructed by the sensor line Q by being inserted from the communication opening 132a. And can enter. Therefore, the attachment member 170 is disposed between the sensor base 210 and the attached portion P to which the sensor base 210 is attached without removing the sensor line Q from the sensor base 210. Can do.

Next, the attachment member 170 is screwed and fixed to the attached portion P using the fixing screw N1 (fourth step).
In this modification, the diameter of the circumference in which the fixing screw hole 131 of the attachment member 170 is arranged is the same as the diameter of the circumference in which the first screw hole 213 of the sensor base 210 is arranged. Therefore, since the screw hole on the attached portion P side used when attaching the sensor base 210 to the attached portion P can be used also when fixing the attachment member 170 to the attached portion P, the information transmission adapter When installing 100, it is not necessary to newly provide a screw hole in the attached portion P. Further, when the fire detector 200 is attached to the attachment portion P, a screw having a screw length suitable for the shape and material of the attachment portion P or the surrounding environment is selected and used as the fixing screw N1. In the present modification, the thickness T of the insertion portion of the fixing screw hole 131 is equal to or less than the thickness of the insertion portion of the first screw hole 213 of the sensor base 210 as in the above embodiment. In the same situation as when the sensor base 210 is attached, the attachment member can be used by fixing the fixing screw N1 selected when attaching the fire sensor 200 to the attachment part P. 170 can be fixed to the attached portion P by screwing. Further, when fixing the attachment member 170 to the attached portion P, the fixing screw N1 selected when attaching the fire detector 200 to the attached portion P can be used. The screw to be prepared is only the mounting screw N2.

Next, the sensor base 210 is screwed and attached to the attachment member 170 using the attachment screw N2 (fifth step).
In this modification, the diameter of the circumference in which the attachment screw hole 141 of the attachment member 170 is arranged is the same as the diameter of the circumference in which the first screw hole 213 of the sensor base 210 is arranged. Therefore, the screw hole (first screw hole 213) on the sensor base 210 side used when the sensor base 210 is attached to the attachment portion P is also used when the sensor base 210 is attached to the attachment member 170. Therefore, the sensor base 210 attached to the attached portion P with the fixing screw N1 can be used as it is. That is, when the information transmission adapter 100 is installed, there is no need to newly install a screw hole in the sensor base 210 or replace it with the sensor base 210 dedicated to the information transmission adapter 100.

Next, the base member 110 on which the information transmission module 160 is mounted is attached (inserted) in the space S between the upper plate portion 130 and the sensor base 210 to constitute the information transmission adapter 100 (sixth). Process). When the base member 110 is attached to the space S, the base member 110 is placed on a plane perpendicular to the vertical direction between the upper plate portion 130 of the attachment member 170 and the sensor base 210 attached to the attachment member 170. Slide along.
In this modification, a communication opening 113a that communicates with the outside is formed in the opening 113 of the base member 110, for example, as shown in FIG. When the base member 110 is inserted between the upper plate portion 130 and the sensor base 210 (that is, between the mounted portion P and the sensor base 210), the communication opening 113a is provided with the protrusion 180 and the sensor line. It is provided to avoid interference with Q. That is, when the base member 110 is attached to the space S, the base member 110 can be moved to an appropriate position without being obstructed by the protrusion 180 or the sensor line Q by being inserted from the communication opening 113a.

  Therefore, the base member 110 is disposed between the attached portion P and the sensor base 210 attached to the attached portion P without removing the sensor line Q from the sensor base 210. Can do. Moreover, in this modification, since the guide structure for guiding the attachment / detachment of the base member 110 to / from the space S has a guide structure including the projecting portion 180, the communication opening 113a, and the opening portion 113, the base member The base member 110 can be smoothly attached to an appropriate position simply by sliding the 110 with respect to the attachment member 170.

  Further, on the upper surface of the base member 110, for example, as shown in FIG. 10, a contact avoidance groove 117 for avoiding contact with the fixing screw N1 whose shaft portion is inserted into the fixing screw hole 131 of the attachment member 170. Is provided. In the present modification, the head of the fixing screw N1 protrudes downward from the lower surface of the upper plate portion 130 as in the above embodiment, so that the contact between the base member 110 and the fixing screw N1 is made by the contact avoiding groove 117. Try to avoid. Accordingly, the distance between the base member 110 and the upper plate portion 130 is made larger than the height (length in the vertical direction) of the head of the fixing screw N1, or the thickness of the upper plate portion 130 is set to the head of the fixing screw N1. The information transmitting adapter 100 can be thinned because it is not necessary to increase the size so that the portion is buried in the upper plate portion 130.

Furthermore, the information transmission adapter 100 according to the present modification includes a closing member 190 that closes the front end portion (inlet portion) of the communication opening 113a of the base member 110 from the outside of the protruding portion 180, as shown in FIG. .
11 and 12 are views for explaining the closing member 190 and are perspective views seen from the upper surface side. In addition, in FIG. 11, illustration of the attachment member 170 is abbreviate | omitted.

  For example, as shown in FIG. 11, the closing member 190 is provided with a pair of locking projections 191. Of the pair of locking projections 191, one faces the left side and the other faces the right side. On the other hand, the base member 110 is provided with a pair of locking recesses 118, and the locking protrusions 191 are configured to fit into the locking recesses 118 when the closing member 190 is attached to the base member 110.

By pulling the closing member 190 attached to the base member 110 forward with a predetermined force or more, the wall surface forming (defining) the locking recess 118 is pushed by the locking projection 191, The interval between the locking recess 118 and the other locking recess 118 is increased. Thereby, since the state in which the locking projection 191 is fitted in the locking recess 118 can be released, the closing member 190 can be removed from the base member 110.

  For example, as shown in FIG. 12, a positioning projection 192 projects from the upper surface of the closing member 190. On the other hand, a positioning recess 134 is provided in the upper plate portion 130 of the attachment member 170, and the positioning projection 192 fits into the positioning recess 134 in a state where the closing member 190 is attached to the base member 110 in the space S. It is configured as follows. Therefore, the base member 110 is positioned with respect to the attachment member 170 by fitting the positioning convex portion 192 of the closing member 190 that closes the communication opening 113a of the base member 110 into the positioning concave portion 134 of the attachment member 170. Become.

That is, in the present modification, the locking structure for detachably locking the base member 110 to the space S has a locking structure including the base member 110 and the closing member 190. Even when subjected to such shaking, the state in which the base member 110 is disposed in the space S can be stably maintained. In addition, since the closing member 190 can be removed from the base member 110 simply by pulling the closing member 190 with a predetermined force or more, the base member 110 can be easily attached to and detached from the space S.
Finally, the sensor body 220 is attached to the sensor base 210 (seventh step). In addition, the timing which attaches the sensor main body 220 to the sensor base 210 may be any timing as long as the fifth step is completed.

  As described above, the information transmission adapter 100 inserts the attachment member 170 between the sensor base 210 and the attached portion P, and then is attached to the upper plate portion 130 of the attachment member 170 and the attachment member 170. By simply attaching (sliding) the base member 110 on which the information transmission module 160 is mounted to the space S between the sensor base 210 and the sensor base 210, the fire sensor 200 (near the fire sensor 200) is installed. can do. That is, the information transmission adapter 100 of the present modification can be installed in the vicinity of the fire detector 200 without removing the sensor line Q from the sensor base 210.

In addition, the information transmission adapter 100 according to the present modification can be removed while the attachment member 170 is left in a state where the information transmission adapter 100 is installed in the vicinity of the fire detector 200. Therefore, since the base member 110 on which the information transmission module 160 is mounted can be removed without removing the fixing screw N1, the mounting screw N2, and the sensor line Q, the fire monitoring by the fire sensor 200 is interrupted. The components can be replaced without any change.
