Description

本発明は、ビーコン等の情報発信端末を備える情報発信モジュールを内蔵し火災感知器に取り付けて用いる情報発信ユニット、およびこの情報発信ユニットを備えた情報発信機能付火災感知器に関する。 The present invention relates to an information transmission unit having a built-in information transmission module including an information transmission terminal such as a beacon and attached to a fire detector, and a fire detector with an information transmission function provided with the information transmission unit.

近年、機器固有の識別情報を位置検出用の情報として無線により発信するビーコン等の情報発信端末や当該情報発信端末に電力を供給する電池等を備えた情報発信モジュールが内蔵された火災感知器が建物に設置されることがある。このような位置検出システムでは、複数の情報発信モジュールの各識別情報と各設置箇所とを対応付けたマップ情報が予め用意され、携帯端末装置に与えられる。そして、携帯端末装置を保有して移動する際に、携帯端末装置が建物内において情報発信モジュールからの識別情報を受信することで、受信した識別情報とマップ情報とから建物内で位置を把握するのに利用される。 In recent years, fire detectors with a built-in information transmission terminal such as a beacon that wirelessly transmits identification information unique to a device as information for position detection and an information transmission module equipped with a battery that supplies power to the information transmission terminal have been introduced. It may be installed in a building. In such a position detection system, map information in which each identification information of a plurality of information transmission modules and each installation location are associated with each other is prepared in advance and given to the mobile terminal device. Then, when the mobile terminal device is carried and moved, the mobile terminal device receives the identification information from the information transmission module in the building, and the position in the building is grasped from the received identification information and the map information. It is used for.

ところで、建物の天井等に設置される火災感知器には、上記したような情報発信モジュールが予め内蔵されたアドレス機能付火災感知器の他に、アドレス機能を有しない火災感知器である一般火災感知器もあり、この一般火災感知器にアドレス機能を付与する中継器が提案されている（例えば特許文献１参照）。具体的には、当該中継器は、自己の固有のアドレスを有しており、一般火災感知器が発報すれば、発報信号とともに自己のアドレスを火災受信機に送信可能である。当該中継器のように、例えば情報発信モジュールが搭載された情報発信ユニットを、建物の天井等に設置される火災感知器に取付けることで、情報発信モジュール専用の設置箇所を別途設けることなく、情報発信モジュールを建物の適切な位置に適切な間隔で配置することができる。 By the way, fire detectors installed on the ceiling of a building include a fire detector with an address function that has an information transmission module built in in advance, as well as a general fire that does not have an address function. There is also a detector, and a repeater that imparts an address function to this general fire detector has been proposed (see, for example, Patent Document 1). Specifically, the repeater has its own unique address, and if the general fire detector issues a report, the repeater can transmit its own address to the fire receiver together with the alarm signal. By attaching an information transmission unit equipped with an information transmission module, for example, to a fire detector installed on the ceiling of a building, such as the repeater, information can be obtained without providing a separate installation location for the information transmission module. Calling modules can be placed in the right locations in the building and at the right intervals.

上記特許文献１に記載された中継器は、建物の天井等に固着する感知器ベースと、当該感知器ベースに取付ける感知器本体と、の間に配設されているので、当該中継器を着脱する際には、感知器ベースから感知器本体を外して、感知器ベースと感知器本体との接続を解除する必要がある。しかしながら、感知器ベースと感知器本体との接続が解除されると、火災感知器の火災監視機能が停止した状態となってしまう。すなわち、上記中継器には、火災監視を中断した状態でないと中継器の着脱を行うことができない、という課題がある。
また、中継器を着脱する度に感知器本体を外さなければならないので、上記中継器には、中継器の着脱に大変手間がかかる、という課題もある。 Since the repeater described in Patent Document 1 is arranged between the sensor base fixed to the ceiling of the building and the sensor body attached to the sensor base, the repeater can be attached and detached. When doing so, it is necessary to remove the sensor body from the sensor base and disconnect the sensor base from the sensor body. However, when the connection between the sensor base and the sensor body is disconnected, the fire monitoring function of the fire detector is stopped. That is, the repeater has a problem that the repeater cannot be attached / detached unless the fire monitoring is interrupted.
Further, since the sensor main body must be removed each time the repeater is attached / detached, the repeater also has a problem that it takes a lot of time and effort to attach / detach the repeater.

本発明は、上記のような課題を解決するためになされたもので、建物の天井等に設置された火災感知器の近傍に取り付け可能な情報発信ユニットであって、火災感知器による火災監視を中断することなく容易に着脱することのできる情報発信ユニットを提供することを目的とする。 The present invention has been made to solve the above problems, and is an information transmission unit that can be attached in the vicinity of a fire detector installed on the ceiling of a building or the like, and can monitor a fire by the fire detector.

本発明によれば、情報発信ユニットの筐体を火災感知器の取り付けたい箇所に配置し、当該箇所にボタン部材を押し付けるだけで鉤爪が火災感知器の開口窓に入り込むので、火災感知器へ容易に取り付けることができる。また、ボタン部材を火災感知器側に再度押し付けるだけで鉤爪が開口窓から出るので、火災感知器から容易に取り外すことができる。つまり、火災感知器の一部または全体を着脱する必要が無いので、着脱の際にも火災感知器による火災の監視状態が継続させることができる。よって、火災感知器による火災監視を中断することなく容易に着脱することができる。
また、火災感知器の表面にある開口窓に係止部を係合させることで取り付けるので、既設の火災感知器にも取り付けが可能である。
また、取り付ける際に、一方の手で筐体を持ち他方の手で可動部を操作するといったことが必要無くなるので、片手で容易に着脱することができる。 According to the present invention, the housing of the information transmission unit is placed at a place where the fire detector is to be attached , and the claws enter the opening window of the fire detector simply by pressing the button member at the place, so that the fire detector can be easily installed. Can be attached to. Further, since the claws come out from the opening window simply by pressing the button member against the fire detector side again, it can be easily removed from the fire detector. That is, since it is not necessary to attach / detach a part or the whole of the fire detector, the fire monitoring state by the fire detector can be continued even when the fire detector is attached / detached. Therefore, it can be easily attached and detached without interrupting the fire monitoring by the fire detector.
Further, since it is attached by engaging the locking portion with the opening window on the surface of the fire detector, it can be attached to the existing fire detector.
Further, when attaching, it is not necessary to hold the housing with one hand and operate the movable part with the other hand, so that it can be easily attached and detached with one hand.

また、上記発明において、前記筐体には、少なくとも前記筐体の表面において前記ボタン部材よりも広い幅で開口する凹部が形成され、前記ボタン部材の基端は、前記凹部の中に収められ、前記鉤爪は、前記ボタン部材の側面に、前記ボタン部材の移動方向と直交する方向に延びる軸を回転の中心として回動可能となるように軸支された棒状のアームの先端に設けられており、前記ボタン部材が前記第１状態から前記第２状態に移行する途中で、前記アームが前記筐体の表面における前記凹部の縁に当接することで前記アームが回動し、前記鉤爪が前記ボタン部材の先端側へ向かうものとしてもよい。
このようにすれば、ボタン部材の動きを伝達するために歯車等の複雑な部材を用いることなく、鉤爪を動作させることができるので、構造が簡素になって製造コストを下げることができるし、筐体内にモジュールを内蔵するためのスペースをより多く確保することもできる。 Further, in the above invention, the housing is formed with a recess that opens at least on the surface of the housing with a width wider than that of the button member, and the base end of the button member is housed in the recess. The claw is provided on the side surface of the button member at the tip of a rod-shaped arm pivotally supported so as to be rotatable about an axis extending in a direction orthogonal to the moving direction of the button member as the center of rotation. the in the middle of the button member transitions from the first state to the second state, and the arms pivot by the arm abuts against the edge of the recess in the surface of the housing, wherein the claw is above It may be directed toward the tip side of the button member.
In this way, the claws can be operated without using complicated members such as gears to transmit the movement of the button member, so that the structure can be simplified and the manufacturing cost can be reduced. It is also possible to secure more space for incorporating the module in the housing.

また、上記発明において、前記ボタン部材は、ハート状カム方式により前記第１状態と前記第２状態とに状態を交互に変えるよう構成されており、前記ボタン部材は、弾性部材によって前記筐体から離れる方向に付勢され、前記第２状態においても、先端部が前記筐体の表面から突出しているものとしてもよい。
このようにすれば、火災感知器に取り付けるときに第２状態のボタン部材が火災感知器に当接可能となるので、鉤爪によって火災感知器に係合しつつ、ボタン部材が火災感知器を押す（本発明が火災感知器から離れるように付勢される）ので、火災感知器に取り付ける際の本発明の安定性を高めることができる。
また、ボタン部材が第２状態においても突出しているので、火災感知器の表面が平坦であっても、火災感知器に取り付けられた状態の本発明を押し付けるだけで容易にボタン部材が押圧され、ボタン部材が第２状態から第１状態へ移行する。このため、本発明を火災感知器から容易に取り外すことができる。 Further, in the above invention, the button member is configured to alternately change the state between the first state and the second state by a heart-shaped cam method, and the button member is formed from the housing by an elastic member. It may be urged in the direction of separation, and the tip portion may protrude from the surface of the housing even in the second state.
In this way, the button member in the second state can come into contact with the fire detector when it is attached to the fire detector, so that the button member pushes the fire detector while engaging with the fire detector by the hook claw. (The present invention is urged away from the fire detector), so that the stability of the present invention when attached to the fire detector can be enhanced.
Further, since the button member is projected even in the second state, even if the surface of the fire detector is flat, the button member can be easily pressed by simply pressing the present invention attached to the fire detector. The button member shifts from the second state to the first state. Therefore, the present invention can be easily removed from the fire detector.

火災感知器のうち煙感知器は、主に天井面（取付面）に沿って側方から流れてくる煙を検知することが知られている。そこで、本発明によれば、情報発信ユニットが煙感知器の下方に位置し、側周面の開口窓を遮蔽しないので、天井面に沿って流れてくる煙が遮られることなく煙感知器内の煙検知部に届く。従って、煙感知器の煙感知性能を低下させることなく、煙感知器に情報発信機能を付加することができる。 Further, the fire detector with an information transmission function of the present invention includes a smoke detector having an opening window formed on a side peripheral surface and an information transmission unit according to the present invention, and the information transmission unit is the button member. Is in contact with a surface of the smoke detector that becomes a lower surface when attached to the attachment surface, and the hook claw is engaged with the window frame portion of the opening window.
Among the fire detectors, the smoke detector is known to mainly detect smoke flowing from the side along the ceiling surface (mounting surface). Therefore, according to the present invention, since the information transmission unit is located below the smoke detector and does not block the opening window on the side peripheral surface, the smoke flowing along the ceiling surface is not blocked inside the smoke detector. Reach the smoke detector. Therefore, it is possible to add an information transmission function to the smoke detector without deteriorating the smoke detection performance of the smoke detector.

また、本発明の情報発信機能付火災感知器は、複数の開口窓に囲まれるように火災検知部が設けられた火災感知器と、上記発明に係る情報発信ユニットと、を備え、前記情報発信ユニットは、前記筐体が、前記火災感知器の下端よりも、感知器の取付面（前記火災感知器を取り付ける取付面と対向することになる面）側に位置しており、前記ボタン部材が、前記火災感知器の、取付面へ取り付けた際に側面となる面に当接しているとともに、前記鉤爪が、前記開口窓の窓枠部に係合していることを特徴とする。
煙感知器に本発明の情報発信ユニットが取り付けられると、本発明の情報発信ユニットと対向する開口窓が一部遮蔽されてしまう場合があるが、当該開口窓の遮蔽されていない部分と他の開口窓は遮蔽されることが無いので、煙感知性能をほとんど低下させることなく情報発信機能を付加することができる。
また、煙感知器の下方が空くので、例えば、天井が低い場合などに本発明が圧迫感を与える心配が無い。 Further, the fire detector with an information transmission function of the present invention includes a fire detector provided with a fire detection unit so as to be surrounded by a plurality of opening windows, and an information transmission unit according to the above invention, and the information transmission is performed. The unit is located so that the housing is closer to the mounting surface of the detector (the surface facing the mounting surface on which the fire detector is mounted) than the lower end of the fire detector, and the button member is The fire detector is in contact with a surface that becomes a side surface when attached to the mounting surface, and the hook claw is engaged with the window frame portion of the opening window.
When the information transmission unit of the present invention is attached to the smoke detector, the opening window facing the information transmission unit of the present invention may be partially shielded, but the unshielded portion of the opening window and other parts may be shielded. Since the opening window is not shielded, an information transmission function can be added with almost no deterioration in smoke detection performance.
Further, since the lower part of the smoke detector is vacant, there is no concern that the present invention gives a feeling of oppression when the ceiling is low, for example.

本発明によれば、火災感知器による火災監視を中断することなく容易に着脱することができる。 According to the present invention, it can be easily attached and detached without interrupting fire monitoring by a fire detector.

係合機構１４０は、筐体１３０の凹部１３１に設けられたラッチ機構１４１と、ラッチ機構１４１の側面に設けられた複数の係止部材１４６と、を備えている。
ラッチ機構１４１は、図３に示したように、筒状のボタン部材１４２と、ボタン部材１４２の中に設けられたプレート１４３と、筐体１３０の凹部１３１の底面１３１ｂからボタン部材１４２の中にかけて設けられたピン１４４と、筐体１３０の凹部１３１の底面１３１ｂとボタン部材１４２との間に設けられた付勢部材１４５と、を備えている。 The engaging mechanism 140 includes a latch mechanism 141 provided in the recess 131 of the housing 130, and a plurality of locking members 146 provided on the side surface of the latch mechanism 141.
As shown in FIG. 3, the latch mechanism 141 extends from the tubular button member 142, the plate 143 provided in the button member 142, and the bottom surface 131b of the recess 131 of the housing 130 to the inside of the button member 142. It includes a pin 144 provided, and an urging member 145 provided between the bottom surface 131b of the recess 131 of the housing 130 and the button member 142.

ボタン部材１４２は、基端部が、筐体１３０の凹部１３１に、凹部１３１の底面１３１ｂと直交する方向に移動可能となるように嵌め込まれている。つまり、ボタン部材１４２は、本発明における、筐体１３０に、該筐体１３０に対して変位可能に設けられた可動部をなす。上述したように、ボタン部材１４２には筒状であり、凹部１３１の上端部はテーパー面１３１ａとなっているので、凹部１３１は、筐体１３０の表面においてボタン部材１４２よりも広い幅で開口していることになる。 The button member 142 is fitted into the recess 131 of the housing 130 so that the base end portion can be moved in a direction orthogonal to the bottom surface 131b of the recess 131. That is, the button member 142 forms a movable portion of the housing 130 in the present invention that is displaceably provided with respect to the housing 130. As described above, since the button member 142 has a tubular shape and the upper end portion of the recess 131 has a tapered surface 131a, the recess 131 opens on the surface of the housing 130 with a width wider than that of the button member 142. It will be.

プレート１４３は、ボタン部材１４２の中にボタン部材１４２の移動方向と平行に立設されている。プレート１４３の一方の表面には、カム溝１４３ａ〜１４３ｄが形成されている。各カム溝１４３ａ〜１４３ｄは、図３に示したように、連続する環状となるように、かつ、全体としてハートに似た形状となるように形成されており、各カム溝１４３ａ〜１４３ｄの終端部は、隣接するカム溝１４３ｂ〜１４３ａよりも浅くなっている。すなわち、各カム溝１４３ａ〜１４３ｄの境界が段差になっている。 The plate 143 is erected in the button member 142 in parallel with the moving direction of the button member 142. Cam grooves 143a to 143d are formed on one surface of the plate 143. As shown in FIG. 3, the cam grooves 143a to 143d are formed so as to form a continuous ring shape and to have a heart-like shape as a whole, and the ends of the cam grooves 143a to 143d. The portion is shallower than the adjacent cam grooves 143b to 143a. That is, the boundary between the cam grooves 143a to 143d is a step.

ピン１４４は、上端部１４４ａが直角に曲げられた棒状をなしている。ピン１４４の上端部１４４ａはカム溝１４３ａ〜１４３ｄ内に、カム溝１４３ａ〜１４３ｄに沿って摺動可能となるように係合している。ピン１４４の下端部は、筐体１３０の凹部１３１の底面１３１ｂに、プレート１４３のカム溝１４３ａ〜１４３ｄが形成された面と直交するように延びる軸材１４４ｂによって軸支されることで、この軸材１４４ｂを回転の中心として回動可能となっている。
このピン１４４により、ボタン部材１４２は、図４（ａ）に示した筐体１３０上面からの突出長が最も大きい状態（以下第１状態）、図４（ｂ）に示した筐体１３０上面からの突出長が最も小さい状態（ボタン部材１４２の上面が筐体１３０の上面と面一またはそれよりも落ち窪んだ状態も含む、以下第３状態）、図４（ｃ）に示した筐体１３０上面からの突出長が第１状態よりは小さく第３状態よりは大きい状態（以下第２状態）等、複数の状態にて静止することが可能となっている。 The pin 144 has a rod shape in which the upper end portion 144a is bent at a right angle. The upper end portion 144a of the pin 144 is engaged in the cam grooves 143a to 143d so as to be slidable along the cam grooves 143a to 143d. The lower end of the pin 144 is pivotally supported on the bottom surface 131b of the recess 131 of the housing 130 by a shaft member 144b extending so as to be orthogonal to the surface on which the cam grooves 143a to 143d of the plate 143 are formed. The material 144b can be rotated around the center of rotation.
Due to the pin 144, the button member 142 has the largest protrusion length from the upper surface of the housing 130 shown in FIG. 4A (hereinafter referred to as the first state), and the button member 142 from the upper surface of the housing 130 shown in FIG. 4B. The housing 130 shown in FIG. 4 (c) has the smallest protrusion length (including a state in which the upper surface of the button member 142 is flush with the upper surface of the housing 130 or is recessed below it). It is possible to stand still in a plurality of states, such as a state in which the protrusion length from the upper surface is smaller than the first state and larger than the third state (hereinafter referred to as the second state).

付勢部材１４５は、例えばスプリング等であり、図３に示したように、筐体１３０の凹部１３１の底面１３１ｂとボタン部材１４２の下端との間に配置されている。そして、付勢部材１４５は、ボタン部材１４２を底面１３１ｂから離れる方向に向かうように付勢している。 The urging member 145 is, for example, a spring or the like, and is arranged between the bottom surface 131b of the recess 131 of the housing 130 and the lower end of the button member 142 as shown in FIG. Then, the urging member 145 urges the button member 142 so as to move away from the bottom surface 131b.

係止部材１４６は、棒状のアーム部１４６ａと、アーム部１４６ａの先端部に形成された鉤爪部１４６ｂと、からなる。アーム部１４６ａは、その基端部が、ボタン部材１４２の側面に、ボタン部材１４２の移動方向と直交するように延びる軸材１４６ｃによって軸支されることで、この軸材１４６ｃを回転の中心として回動可能となっている。鉤爪部１４６ｂは略上方を向いている。また、係止部材１４６は、図示しない弾性部材によって、アーム部１４６ａが上方に向かって傾斜した状態から、図３に示したボタン部材１４２の移動方向に直交する状態へと延びる方向、すなわち、複数の鉤爪部１４６ｂが互いに遠ざかる方向に回動するよう付勢されている。 The locking member 146 includes a rod-shaped arm portion 146a and a claw portion 146b formed at the tip end portion of the arm portion 146a. The base end of the arm portion 146a is pivotally supported on the side surface of the button member 142 by a shaft member 146c extending so as to be orthogonal to the moving direction of the button member 142, so that the shaft member 146c is used as the center of rotation. It is rotatable. The claw portion 146b faces substantially upward. Further, the locking member 146 is provided in a direction extending from a state in which the arm portion 146a is inclined upward by an elastic member (not shown) to a state orthogonal to the moving direction of the button member 142 shown in FIG. 3, that is, a plurality of locking members 146. The claw portions 146b of the above are urged to rotate in a direction away from each other.

係止部材１４６の軸支部（軸材１４６ｃ）は、図４（ａ）に示したように、ボタン部材１４２が第１状態のときに筐体１３０の上面よりも上方に位置し、図４（ｂ）に示したように、ボタン部材１４２が第３状態のときにテーパー面１３１ａの下端の高さに位置し、図４（ｃ）に示したように、第２状態のときに筐体１３０の上面よりも下方に位置するよう配置されている。このため、係止部材１４６のアーム部１４６ａは、ボタン部材１４２が第１状態から第２状態へ移行する手前の段階で筐体１３０の凹部１３１の縁に当接することになる。 As shown in FIG. 4A, the shaft support portion (shaft member 146c) of the locking member 146 is located above the upper surface of the housing 130 when the button member 142 is in the first state, and is located in FIG. 4 (a). As shown in b), the button member 142 is located at the height of the lower end of the tapered surface 131a in the third state, and as shown in FIG. 4C, the housing 130 is in the second state. It is arranged so as to be located below the upper surface of the. Therefore, the arm portion 146a of the locking member 146 comes into contact with the edge of the recess 131 of the housing 130 at a stage before the button member 142 shifts from the first state to the second state.

係合機構１４０は、このように構成されることで、ラッチ機構１４１がオルタネイト動作し、それに伴って係止部材１４６が回動する（各鉤爪部１４６ｂがボタン部材の先端側へ向かったり側方側に向かったり（互いに近づいたり離れたり）する）。つまり、鉤爪部１４６ｂは、本発明における、可動部の変位に伴い所定の変位動作が可能な係止部をなす。具体的には、図４（ａ）に示したように、ボタン部材１４２が第１状態のとき、ピン１４４の上端部１４４ａは第１カム溝１４３ａの下端に係合している。
このとき、係止部材１４６には、筐体１３０が当接しておらず、軸支部の図示しない弾性部材による付勢力しか作用しないので、アーム部１４６ａがボタン部材１４２の移動方向と直交する方向に延びた状態（各鉤爪部１４６ｂが離れた状態）となっている。 When the engaging mechanism 140 is configured in this way, the latch mechanism 141 alternates, and the locking member 146 rotates accordingly (each claw portion 146b faces the tip side of the button member or sideways). Turn to the side (approach or move away from each other). That is, the claw portion 146b forms a locking portion in the present invention capable of performing a predetermined displacement operation with the displacement of the movable portion. Specifically, as shown in FIG. 4A, when the button member 142 is in the first state, the upper end portion 144a of the pin 144 is engaged with the lower end of the first cam groove 143a.
At this time, since the housing 130 is not in contact with the locking member 146 and only the urging force of the elastic member (not shown) of the shaft support portion acts on the locking member 146, the arm portion 146a is in the direction orthogonal to the moving direction of the button member 142. It is in an extended state (a state in which each claw portion 146b is separated).

この状態でボタン部材１４２に下方向の押圧力を作用させると、ボタン部材１４２が筐体１３０の中に入り込んでいく。このとき、ピン１４４の上端部１４４ａは、第１カム溝１４３ａおよび第２カム溝１４３ｂにガイドされる。上端部１４４ａが第２カム溝１４３ｂの上端に達すると、図４（ｂ）に示したように、ボタン部材１４２が第３状態となる。
このとき、係止部材１４６の軸支部がテーパー面１３１ａの下端に位置するので、アーム部１４６ａがテーパー面１３１ａに沿って傾斜し、各鉤爪部１４６ｂがボタン部材１４２の先端側において最も近づいた状態となる。 When a downward pressing force is applied to the button member 142 in this state, the button member 142 enters the housing 130. At this time, the upper end portion 144a of the pin 144 is guided by the first cam groove 143a and the second cam groove 143b. When the upper end portion 144a reaches the upper end of the second cam groove 143b, the button member 142 is in the third state as shown in FIG. 4B.
At this time, since the shaft support portion of the locking member 146 is located at the lower end of the tapered surface 131a, the arm portion 146a is inclined along the tapered surface 131a, and each claw portion 146b is closest to the tip side of the button member 142. It becomes.

この状態でボタン部材１４２に対する押圧力を無くすと、ボタン部材１４２は付勢部材１４５の付勢力によって押し戻される。このとき、ピン１４４の上端部１４４ａは、第１カム溝１４３ａと第２カム溝１４３ｂとの間の段差により、第１カム溝１４３ａには戻らず、第２カム溝１４３ｂにガイドされる。上端部１４４ａが第３カム溝１４３ｃの下端に達すると、図４（ｃ）に示したように、ボタン部材１４２が第２状態となる。
このとき、係止部材１４６の軸支部が筐体１３０の上面よりも下方に位置するので、アーム部１４６ａが、テーパー面１３１ａの傾斜よりも緩やかな角度で傾斜し、各鉤爪部１４６ｂが最も離れた状態よりは近く最も近づいた状態よりは離れた状態となる。 When the pressing force on the button member 142 is released in this state, the button member 142 is pushed back by the urging force of the urging member 145. At this time, the upper end portion 144a of the pin 144 does not return to the first cam groove 143a due to the step between the first cam groove 143a and the second cam groove 143b, but is guided by the second cam groove 143b. When the upper end portion 144a reaches the lower end of the third cam groove 143c, the button member 142 is in the second state as shown in FIG. 4C.
At this time, since the shaft support portion of the locking member 146 is located below the upper surface of the housing 130, the arm portion 146a is inclined at an angle gentler than the inclination of the tapered surface 131a, and the claw portions 146b are farthest apart. It will be closer than the state of being closer and farther than the state of being closest.

この状態でボタン部材１４２に押圧力を再度作用させると、ボタン部材１４２が筐体１３０の中に再度入り込んでいく。このとき、ピン１４４の上端部１４４ａは、第３カム溝１４３ｃおよび第４カム溝１４３ｄにガイドされる。上端部１４４ａが第４カム溝１４３ｄの上端に達すると、図４（ｄ）に示したように、ボタン部材１４２が再び第３状態となる。
このとき、係止部材１４６は、アーム部１４６ａがテーパー面１３１ａに沿って傾斜した状態となる。 When the pressing force is applied to the button member 142 again in this state, the button member 142 reenters the housing 130. At this time, the upper end portion 144a of the pin 144 is guided by the third cam groove 143c and the fourth cam groove 143d. When the upper end portion 144a reaches the upper end of the fourth cam groove 143d, the button member 142 is in the third state again as shown in FIG. 4D.
At this time, the locking member 146 is in a state in which the arm portion 146a is inclined along the tapered surface 131a.

この状態でボタン部材１４２に対する押圧力を無くすと、ボタン部材１４２は付勢部材１４５の付勢力によって押し戻される。このとき、ピン１４４の上端部１４４ａは、第３カム溝１４３ｃと第４カム溝１４３ｄとの間の段差により、第３カム溝１４３ｃには戻らず、第４カム溝１４３ｄにガイドされる。上端部１４４ａが第１カム溝１４３ａの下端に達すると、ボタン部材１４２が図４（ａ）に示した第１状態に戻る。
このとき、係止部材１４６は、アーム部１４６ａがボタン部材１４２の移動方向と直交する方向に延びた状態となる。
なお、ボタン部材１４２をオルタネイト動作させる方式は、ここで例示したハート状カム方式に限られず、回転カム方式、ラチェットカム方式等を採用してもよい。 When the pressing force on the button member 142 is released in this state, the button member 142 is pushed back by the urging force of the urging member 145. At this time, the upper end portion 144a of the pin 144 does not return to the third cam groove 143c due to the step between the third cam groove 143c and the fourth cam groove 143d, but is guided by the fourth cam groove 143d. When the upper end portion 144a reaches the lower end of the first cam groove 143a, the button member 142 returns to the first state shown in FIG. 4A.
At this time, the locking member 146 is in a state in which the arm portion 146a extends in a direction orthogonal to the moving direction of the button member 142.
The method of operating the button member 142 in an alternate manner is not limited to the heart-shaped cam method illustrated here, and a rotary cam method, a ratchet cam method, or the like may be adopted.

このように構成された情報発信ユニット１００Ｂを、天井Ｃに取り付けられた感知器本体１００Ａへ取り付けるには、まず、図５（ａ）に示したように、情報発信ユニット１００Ｂのボタン部材１４２を第１状態としておき、ボタン部材１４２の上面を、感知器本体１００Ａの下面（蓋体１２４）に当接させながら、情報発信ユニット１００Ｂを上方へ押し付ける。すると、ボタン部材１４２が感知器本体１００Ａに押されて第１状態から第３状態に移行するとともに、係止部材１４６が筐体１３０に押されて回動する。すると、図５（ｂ）に示したように、各係止部材１４６の鉤爪部１４６ｂが、感知器本体１００Ａの開口窓１２０ｂにそれぞれ入り込み、リング状の導光散乱部材１２１に引っ掛かる。つまり、導光散乱部材１２１は、本発明における、火災感知器の表面にある係合可能な箇所、或いは、開口窓の窓枠部をなす。 In order to attach the information transmission unit 100B configured in this way to the sensor body 100A attached to the ceiling C, first, as shown in FIG. 5A, the button member 142 of the information transmission unit 100B is first attached. In the 1 state, the information transmission unit 100B is pressed upward while the upper surface of the button member 142 is brought into contact with the lower surface (lid body 124) of the sensor body 100A. Then, the button member 142 is pushed by the sensor main body 100A to shift from the first state to the third state, and the locking member 146 is pushed by the housing 130 to rotate. Then, as shown in FIG. 5B, the claw portion 146b of each locking member 146 enters the opening window 120b of the sensor main body 100A, and is caught by the ring-shaped light guide scattering member 121. That is, the light guide scattering member 121 forms an engageable portion on the surface of the fire detector or the window frame portion of the opening window in the present invention.

ここで手を放すと、ボタン部材１４２が押し返されて第３状態から第２状態に移行し、係止部材１４６の各鉤爪部１４６ｂ同士が僅かに離れるが、情報発信ユニット１００Ｂが感知器本体１００Ａに係合した状態が保たれる。こうして、感知器本体１００Ａと情報発信ユニット１００Ｂが一体化し、情報発信機能付火災感知器１００となる。なお、このとき、第２状態のボタン部材１４２が感知器本体１００Ａの下面に当接するので、鉤爪部１４６ｂによって感知器本体１００Ａに係合しつつ、ボタン部材１４２が感知器本体１００Ａの下面を押す（情報発信ユニット１００Ｂが感知器本体１００Ａから離れるように付勢される）ので、感知器本体１００Ａに取り付ける際の情報発信ユニット１００Ｂの安定性が高まる。 When the hand is released here, the button member 142 is pushed back and shifts from the third state to the second state, and the claw portions 146b of the locking member 146 are slightly separated from each other, but the information transmission unit 100B is the sensor main body. The state of being engaged with 100A is maintained. In this way, the sensor main body 100A and the information transmission unit 100B are integrated to form a fire detector 100 with an information transmission function. At this time, since the button member 142 in the second state comes into contact with the lower surface of the sensor main body 100A, the button member 142 pushes the lower surface of the sensor main body 100A while engaging with the sensor main body 100A by the claw portion 146b. (The information transmission unit 100B is urged so as to be separated from the sensor main body 100A), so that the stability of the information transmission unit 100B when attached to the sensor main body 100A is enhanced.

感知器本体１００Ａから情報発信ユニット１００Ｂを取り外すには、まず、情報発信ユニット１００Ｂを上方へ押し手を放す。すると、ボタン部材１４２が第２状態から第３状態を経て第１状態へと戻る。このとき、ボタン部材１４２が第２状態においても突出しているので、感知器本体１００Ａの下面が平坦であっても、感知器本体１００Ａに取り付けられた状態の情報発信ユニット１００Ｂを押し付けるだけで容易にボタン部材１４２が押圧され、ボタン部材１４２が第２状態から第１状態へ移行する。そして、係止部材１４６の鉤爪部１４６ｂが開口窓１２０ｂから抜ける。こうして、情報発信機能付火災感知器１００が、感知器本体１００Ａと情報発信ユニット１００Ｂとに分離される。 To remove the information transmission unit 100B from the sensor body 100A, first push the information transmission unit 100B upward and release it. Then, the button member 142 returns from the second state to the first state through the third state. At this time, since the button member 142 is projected even in the second state, even if the lower surface of the sensor main body 100A is flat, it is easy to simply press the information transmission unit 100B attached to the sensor main body 100A. The button member 142 is pressed, and the button member 142 shifts from the second state to the first state. Then, the claw portion 146b of the locking member 146 comes out of the opening window 120b. In this way, the fire detector 100 with an information transmission function is separated into the sensor main body 100A and the information transmission unit 100B.

＜第２実施形態＞
次に、本発明の第２実施形態について説明する。なお、ここでは、第１実施形態との相違点についてのみ説明する。
まず、本実施形態に係る情報発信機能付火災感知器２００の概略構成について説明する。図６は、情報発信機能付火災感知器２００の情報発信ユニット取り付け前後における下面図である。
本実施形態の情報発信機能付火災感知器２００は、感知器本体が煙感知器でも熱感知器でもよい点が第１実施形態と異なっている（図６には、便宜上第１実施形態と同じ煙感知器を示している）。なお、熱感知器を用いる場合、サーミスタが本発明における火災検知部となる。また、当該サーミスタは、柵状体に囲まれて保護される（すなわち、本発明の熱流入用の開口窓と窓枠部として構成される）。
また、本実施形態の情報発信機能付火災感知器２００は、情報発信ユニット２００Ｂが感知器本体１００Ａの側方に取り付けられている点が第１実施形態と異なっている。 <Second Embodiment>
Next, the second embodiment of the present invention will be described. Here, only the differences from the first embodiment will be described.
First, a schematic configuration of the fire detector 200 with an information transmission function according to the present embodiment will be described. FIG. 6 is a bottom view of the fire detector 200 with an information transmission function before and after the information transmission unit is attached.
The fire detector 200 with an information transmission function of the present embodiment is different from the first embodiment in that the sensor main body may be a smoke detector or a heat detector (FIG. 6 is the same as the first embodiment for convenience). Shows a smoke detector). When a heat detector is used, the thermistor is the fire detection unit in the present invention. Further, the thermistor is surrounded and protected by a fence-like body (that is, it is configured as an opening window and a window frame portion for heat inflow of the present invention).
Further, the fire detector 200 with an information transmission function of the present embodiment is different from the first embodiment in that the information transmission unit 200B is attached to the side of the sensor main body 100A.

次に、情報発信ユニットの具体的構成について説明する。
本実施形態の情報発信ユニット２００Ｂは、筐体２３０の側面に係合機構２４０が設けられている。
本実施形態の係合機構２４０は、第１実施形態と同様に、ラッチ機構２４１と、係止部材２４６と、を備えているが、ラッチ機構２４１のオルタネイト動作が、筐体２３０の側面と直交する方向に沿って行われる点が第１実施形態と異なっている。
また、本実施形態の係止部材２４６は、アーム部２４６ａが第１実施形態よりも細く形成されている。
また、本実施形態の筐体２３０は、係止部材の回転軸に沿う方向（図６の紙面と直交する方向）の厚さが、第１実施形態よりも短くなっている。具体的には、感知器本体１００Ａの取り付け時に天井と対向することになる面から暗箱１１８内の検知室までの距離を超えない程度となっている。 Next, a specific configuration of the information transmission unit will be described.
The information transmission unit 200B of the present embodiment is provided with an engaging mechanism 240 on the side surface of the housing 230.
The engagement mechanism 240 of the present embodiment includes the latch mechanism 241 and the locking member 246 as in the first embodiment, but the alternate operation of the latch mechanism 241 is orthogonal to the side surface of the housing 230. It is different from the first embodiment in that it is performed along the direction of the first embodiment.
Further, in the locking member 246 of the present embodiment, the arm portion 246a is formed thinner than that of the first embodiment.
Further, the thickness of the housing 230 of the present embodiment in the direction along the rotation axis of the locking member (direction orthogonal to the paper surface of FIG. 6) is shorter than that of the first embodiment. Specifically, the distance from the surface facing the ceiling when the sensor main body 100A is attached to the detection chamber in the dark box 118 is not exceeded.

このように構成された情報発信ユニット２００Ｂを、天井に取り付けられた感知器本体１００Ａへ取り付けるには、まず、図６（ａ）に示したように、情報発信ユニット２００Ｂのボタン部材２４２を第１状態としておき、ボタン部材２４２の上面を天井面に当接させるとともに、側面を感知器本体１００Ａの側面に当接させながら、情報発信ユニット２００Ｂを感知器本体１００Ａの方へ押し付けた後に手を放す。すると、図６（ｂ）に示したように、各係止部材２４６の鉤爪部２４６ｂが、感知器本体１００Ａの開口窓１２０ｂにそれぞれ入り込み、感知器カバー１２０の、隣接する二つの開口窓１２０ｂの間にある部位に引っ掛かる。こうして、感知器本体１００Ａと情報発信ユニット２００Ｂが一体化し、情報発信機能付火災感知器２００となる。つまり、隣接する二つの開口窓１２０ｂの間にある部位は、本発明における、火災感知器の表面にある係合可能な箇所、或いは、開口窓の窓枠部をなす。 In order to attach the information transmission unit 200B configured in this way to the sensor body 100A mounted on the ceiling, first, as shown in FIG. 6A, the button member 242 of the information transmission unit 200B is first attached. In this state, the upper surface of the button member 242 is brought into contact with the ceiling surface, and the side surface is brought into contact with the side surface of the sensor main body 100A, while the information transmission unit 200B is pressed toward the sensor main body 100A and then released. .. Then, as shown in FIG. 6B, the claw portion 246b of each locking member 246 enters the opening window 120b of the sensor main body 100A, respectively, and the two adjacent opening windows 120b of the sensor cover 120 It gets caught in the part in between. In this way, the sensor main body 100A and the information transmission unit 200B are integrated to form a fire detector 200 with an information transmission function. That is, the portion between the two adjacent opening windows 120b forms the engaging portion on the surface of the fire detector or the window frame portion of the opening window in the present invention.

なお、情報発信ユニット２００Ｂは、感知器本体１００Ａに上述したように係合することで、図６（ｂ）に示したように、一の開口窓１２０ｂと対向することになるが、上述したように、筐体２３０の厚さは薄いので、情報発信ユニット２００Ｂの下面は、暗箱１１８内の検出室よりも上（天井と対向する面側）に位置することになる。上述したように、検出室と各開口窓１２０ｂはほぼ同じ高さに位置するため、情報発信ユニット２００Ｂと対向する開口窓１２０ｂは、遮蔽されるとしてもその範囲はごくわずかにとどまる。また、係止部材２４６のアーム部２４６ａが細く形成されているので、係止部材２４６によって開口窓１２０ｂが遮蔽される範囲も最小限に留まる。従って、この開口窓１２０ｂにも、他の開口窓１２０ｂと同様に煙の流入が可能となるので、感知器本体１００Ａは、側方に情報発信ユニット２００Ｂが取り付けられていても、求められる煙検知性能を十分に満たすことができる。 By engaging the information transmission unit 200B with the sensor main body 100A as described above, the information transmission unit 200B faces the one opening window 120b as shown in FIG. 6B, but as described above. Since the thickness of the housing 230 is thin, the lower surface of the information transmission unit 200B is located above the detection chamber in the dark box 118 (the surface facing the ceiling). As described above, since the detection chamber and each opening window 120b are located at substantially the same height, the range of the opening window 120b facing the information transmission unit 200B is very small even if it is shielded. Further, since the arm portion 246a of the locking member 246 is formed thin, the range in which the opening window 120b is shielded by the locking member 246 is also minimized. Therefore, smoke can flow into this opening window 120b as well as other opening windows 120b, so that the sensor main body 100A can detect smoke even if the information transmission unit 200B is attached to the side. The performance can be fully satisfied.

以上説明してきたように、上記実施形態の情報発信ユニット１００Ｂ，２００Ｂは、ボタン部材１４２，２４２の動作に基づいて鉤爪部１４６ｂ，２４６ｂが近づいたり離れたりする複数の係止部材１４６，２４６によって、感知器本体１００Ａに係合するので、感知器本体１００Ａの下面または側面にボタン部材１４２，２４２を押し付けるだけで容易に取り付けることができ、ボタン部材１４２，２４２を感知器本体側に再度押し付けるだけで容易に取り外すことができる。つまり、感知器本体１００Ａの一部または全体を着脱する必要が無いので、着脱の際にも感知器本体１００Ａによる火災の監視状態が継続させることができる。よって、感知器本体１００Ａによる火災監視を中断することなく容易に着脱することができる。 As described above, the information transmission units 100B and 200B of the above-described embodiment are provided with a plurality of locking members 146 and 246 from which the claw portions 146b and 246b approach and separate based on the operation of the button members 142 and 242. Since it engages with the sensor body 100A, it can be easily attached by simply pressing the button members 142 and 242 against the lower surface or the side surface of the sensor body 100A, and by simply pressing the button members 142 and 242 against the sensor body side again. It can be easily removed. That is, since it is not necessary to attach / detach a part or the whole of the sensor main body 100A, the fire monitoring state by the sensor main body 100A can be continued even when the sensor main body 100A is attached / detached. Therefore, the fire monitoring by the sensor main body 100A can be easily attached and detached without interruption.

また、感知器本体の表面にある開口窓１２０ｂの周囲に鉤爪部１４６ｂを係合させることで取り付けるので、既設の火災感知器にも取り付けが可能である。
また、火災（煙または熱）の感知機能しか有していない既設の感知器本体の付加価値を高めることができるし、筐体１３０，２３０の中の部品を取り換えることで、感知器本体１００Ａに付加する機能を容易に切り替えることができる。
また、取り外しも容易なため、電源交換等のメンテナンスを容易に行うことができる。 Further, since it is attached by engaging the claw portion 146b around the opening window 120b on the surface of the sensor main body, it can be attached to an existing fire detector.
In addition, it is possible to increase the added value of the existing sensor body that has only a fire (smoke or heat) detection function, and by replacing the parts inside the housings 130 and 230, the sensor body 100A can be used. The function to be added can be easily switched.
Moreover, since it is easy to remove, maintenance such as power supply replacement can be easily performed.

また、上記実施形態の情報発信ユニット１００Ｂ，２００Ｂは、係止部材１４６のアーム部１４６ａを筐体１３０に当てて回動させる係合機構１４０を採用しているので、筐体１３０にボタン部材１４２の動きを係止部材１４６に伝達するために歯車等の複雑な部材を用いる必要がなく、簡素な構成で係止部材を動作させることができるので、製造コストを下げることができるし、筐体内にモジュールを内蔵するためのスペースをより多く確保することもできる。 Further, since the information transmission units 100B and 200B of the above-described embodiment employ the engaging mechanism 140 in which the arm portion 146a of the locking member 146 is brought into contact with the housing 130 to rotate, the button member 142 is attached to the housing 130. Since it is not necessary to use a complicated member such as a gear to transmit the movement of the locking member to the locking member 146, and the locking member can be operated with a simple configuration, the manufacturing cost can be reduced and the inside of the housing can be reduced. It is also possible to secure more space for incorporating the module in the gear.

また、第１実施形態では、感知器本体１００Ａを煙感知器とし、情報発信ユニット１００Ｂを感知器本体１００Ａの下方に取り付けた。火災時の煙の多くは天井面に沿って感知器本体１００Ａへと流れることが知られているが、第１実施形態の感知器本体１００Ａは、側周面の複数の開口窓１２０ｂが情報発信ユニット１００Ｂに遮蔽されていないので、流れてくる煙が遮られることなく暗箱１１８内の煙を検出するための検知室に届く。
また、第２実施形態では、感知器本体を煙感知器または熱感知器とし、情報発信ユニット２００Ｂを感知器本体の側方に取り付けた。このようにすると、情報発信ユニット２００Ｂによって複数の開口窓１２０ｂの一部が遮蔽される場合があるが、当該開口窓１２０ｂの遮蔽されていない部分と他の多くの開口窓１２０ｂは遮蔽されないので、感知器本体が煙感知器であっても、流れてくる煙がほぼ暗箱１１８内の煙を検出するための検知室に届く。一方、感知器本体が熱感知器である場合、火災時の熱は鉛直上方に向かい易いので、下方から届く熱が遮られることなくサーミスタに届く。
従って、感知器本体の感知性能を低下させることなく、感知器本体に情報発信機能を付加することができる。 Further, in the first embodiment, the sensor main body 100A is used as a smoke detector, and the information transmission unit 100B is attached below the sensor main body 100A. It is known that most of the smoke during a fire flows to the sensor main body 100A along the ceiling surface, but in the sensor main body 100A of the first embodiment, information is transmitted by a plurality of opening windows 120b on the side peripheral surface. Since it is not shielded by the unit 100B, the flowing smoke reaches the detection chamber for detecting the smoke in the dark box 118 without being blocked.
Further, in the second embodiment, the sensor main body is a smoke detector or a heat detector, and the information transmission unit 200B is attached to the side of the sensor main body. In this way, a part of the plurality of opening windows 120b may be shielded by the information transmission unit 200B, but the unshielded portion of the opening window 120b and many other opening windows 120b are not shielded. Even if the sensor body is a smoke detector, the flowing smoke almost reaches the detection room for detecting the smoke in the dark box 118. On the other hand, when the sensor body is a heat detector, the heat at the time of a fire tends to go vertically upward, so that the heat arriving from below reaches the thermistor without being blocked.
Therefore, the information transmission function can be added to the sensor main body without deteriorating the sensing performance of the sensor main body.

また、上記実施形態では、係止部材１４６，２４６を２本としたが、検知性能に影響を及ぼさないよう鉤爪やアームの形状・機構を工夫することで、係止部材を１本、或いは３本以上とすることも可能である。なお、３本以上とすれば、情報発信ユニット１００Ｂ，２００Ｂの、２本の係止部材１４６，２４６の並び方向と直交する方向に対する安定感を高めることができる。
また、上記実施形態では、ラッチ機構の側面に係止部材を設け、ボタン部材が変位する際に係止部材を筐体に当接させることで係止部材を回動させるようにしたが、係止部材をラッチ機構から離して設け、ラッチ機構に合わせて動作するカムや歯車などの伝達機構を介して係止部材を動かすようにしてもよい。 Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments and can be appropriately modified without departing from the spirit of the invention.
