Description

本発明は戸建住宅に設置される火災警報器、特に地震等による脱落や作為的な盗難を簡易的に防止できるロック構造を形成可能な火災警報器に関する。   The present invention relates to a fire alarm installed in a detached house, and more particularly, to a fire alarm capable of forming a lock structure that can easily prevent a drop or an accidental theft due to an earthquake or the like.

この種の火災警報器すなわち戸建住宅に設置される火災警報器は、天井や壁面に取り付けられるベースと、ベースに着脱自在に取り付けられ、煙や熱などを感知して火災を検出する警報器本体とから構成される(例えば、特許文献1参照)。   This type of fire alarm, that is, a fire alarm installed in a detached house, is a base that is attached to the ceiling or wall, and an alarm that is removably attached to the base and detects fire by detecting smoke or heat. It is comprised from a main body (for example, refer patent document 1).

このようなものにおいて、ベースへの警報器本体の取付は、一般にツイストロック機構により行われる。ツイストロック機構は、例えば警報器本体の背面側に設けた刃部と、ベース側に設けられて警報器本体の背面側の刃部を受ける刃受部とから構成され、刃部と刃受部との位置調整を行い、警報器本体をベースに嵌合させてツイスト(相対回動)させることで、刃部を刃受部に係合させ、これによって警報器本体をベースに固定でき、またツイストロック状態下で警報器本体をベースに対して刃部の係合方向とは逆方向にツイストすることで、ベースと警報器本体との係合を解除できるようにしたものである。   In such a thing, attachment of the alarm device body to the base is generally performed by a twist lock mechanism. The twist lock mechanism is composed of, for example, a blade portion provided on the back side of the alarm body and a blade receiving portion provided on the base side for receiving the blade portion on the back side of the alarm body, and the blade portion and the blade receiving portion. The blade is engaged with the blade receiving part by fitting the alarm body to the base and twisting (relative rotation), thereby fixing the alarm body to the base. In the twist lock state, the alarm device body is twisted in the direction opposite to the engagement direction of the blade portion with respect to the base so that the engagement between the base and the alarm device body can be released.

以下、本発明を図示実施形態に基づき説明する。
図1は本発明の一実施形態に係る火災警報器の警報器本体を示す背面図、図2はそのベースを示す正面図、図3はその警報器本体とベースとを組み付けてロックねじを取り付けた状態を示す側面図、図4はその警報器本体とベースとを組み付けてロックねじを取り付けた状態を示す背面図、図5は図4のA−A線矢視断面図である。
Hereinafter, the present invention will be described based on illustrated embodiments.
FIG. 1 is a rear view showing an alarm body of a fire alarm device according to an embodiment of the present invention, FIG. 2 is a front view showing the base thereof, and FIG. 3 is an assembly of the alarm body and base and attaching a lock screw. 4 is a rear view showing a state in which the alarm device body and the base are assembled and a lock screw is attached, and FIG. 5 is a cross-sectional view taken along line AA in FIG.

本実施形態の火災警報器は、天井や壁面に設置されるベース1と、背面側がベース1とツイストロック嵌合可能に形成された警報器本体2とからなり、さらに警報器本体2が、本体3とカバー4とから構成され、これら本体3とカバー4が複数のねじ5によって互いに固定されている。また、警報器本体2には、煙や熱などを感知して火災を検出する火災検出部6としての煙センサが設けられているとともに、内部に電池9や図示しない回路基板、火災を表示するための表示灯、及び火災を報知する音響構造が設けられている。   The fire alarm device of the present embodiment includes a base 1 installed on a ceiling or a wall surface, and an alarm device body 2 formed so that the back side of the base 1 and a twist lock can be fitted. 3 and the cover 4, and the main body 3 and the cover 4 are fixed to each other by a plurality of screws 5. The alarm device body 2 is provided with a smoke sensor as a fire detection unit 6 that detects smoke by detecting smoke or heat, and displays a battery 9, a circuit board (not shown), and a fire inside. For this purpose, there are provided an indicator lamp and an acoustic structure for notifying a fire.

ツイストロック嵌合部は、ベース1に設けられた筒部1aと、筒部1aの内側に嵌合可能に本体3に設けられた筒部3aと、本体3に設けられた筒部3aから内側に延出形成された刃部3bと、ベース1に設けられて刃部3bを受ける刃受部1bとから構成され、刃部3bと刃受部1bとを周方向でずらした状態で筒部3a,1aを嵌合させ、その状態から刃部3bと刃受部1bとが係合する方向に本体3をベース1に対し相対回動させることで、本体3すなわち警報器本体2をベース1にツイストロックできるようになっている。なお、刃受部1bは、筒部1aの内側に設けられた第2筒部1eから外側に延出形成されて断面略L字状に形成されている。   The twist lock fitting portion includes a cylindrical portion 1a provided on the base 1, a cylindrical portion 3a provided on the main body 3 so as to be fitted inside the cylindrical portion 1a, and an inner side from the cylindrical portion 3a provided on the main body 3. And a blade receiving portion 1b that is provided on the base 1 and receives the blade portion 3b, and the cylindrical portion in a state where the blade portion 3b and the blade receiving portion 1b are shifted in the circumferential direction. 3a and 1a are fitted together, and the main body 3 relative to the base 1 is rotated relative to the base 1 in the direction in which the blade portion 3b and the blade receiving portion 1b engage with each other. Can be twist-locked. The blade receiving portion 1b is formed to extend outward from the second cylindrical portion 1e provided inside the cylindrical portion 1a and has a substantially L-shaped cross section.

ツイストロックの解除は、前記と逆の手順により行われる。つまり、本体3側(警報器本体2)をベース1に対し刃部3bと刃受部1bとの係合が外れる方向に相対回動させ、ベース1の筒部1aから本体3の筒部3aを引き抜けば、本体3すなわち警報器本体2をベース1から取り外すことができる。   The twist lock is released according to the reverse procedure. That is, the main body 3 side (alarm device main body 2) is relatively rotated with respect to the base 1 in the direction in which the blade portion 3b and the blade receiving portion 1b are disengaged from the base portion 1a to the base portion 3 of the main body 3. Can be removed from the base 1.

また、本体3には、その一側部の周縁近傍に、ベース1との嵌合部の外方よりロックねじ7が螺着可能な螺着部8が設けられている。螺着部8は、ここでは本体3に形成した孔部3cに別体の四角ナットを嵌着して構成しているが、本体3に直接雌ねじを形成してもよいものである。また、孔部3cに連続して、螺着部8へのロックねじ7の導入をガイドするガイド通路3dが形成されている。   Further, the main body 3 is provided with a threaded portion 8 to which a lock screw 7 can be screwed from the outside of the fitting portion with the base 1 in the vicinity of the peripheral edge of one side portion. Here, the screw portion 8 is configured by fitting a separate square nut into the hole 3c formed in the main body 3, but a female screw may be directly formed on the main body 3. Further, a guide passage 3d that guides introduction of the lock screw 7 into the screwing portion 8 is formed continuously with the hole 3c.

一方、ベース1には、その筒部1aにおける当該ベース1と本体3とがツイストロック状態にあるときの螺着部8に対応する部位に、図2に示すような薄肉部(又はノックアウトされるための切れ込みでもよい)1cが設けられている。薄肉部(又は切れ込み)1cを切り抜いて形成される切欠部1d(図3)は、その切欠エッジが前記ツイストロック状態下で前記螺着部8に螺着されるロックねじ7の頭部と係合可能となるように構成されている。なお、切欠部1dは、はじめから切り抜かれて形成されていてもよい。   On the other hand, the thin portion (or knocked out) as shown in FIG. 2 is formed on the base 1 at a portion corresponding to the screwed portion 8 when the base 1 and the main body 3 are in the twist lock state. 1c) may be provided. A cutout portion 1d (FIG. 3) formed by cutting out the thin-walled portion (or cutout) 1c is engaged with the head of the lock screw 7 whose cutout edge is screwed to the screwing portion 8 under the twist lock state. It is configured to be possible. Note that the cutout 1d may be formed by cutting out from the beginning.

次に、本実施形態の火災警報器を天井や壁面へ設置する手順について説明する。
地震等による警報器本体2の脱落や作為的な盗難を防止したい場合は、まずベース1の薄肉部(又は切れ込み)1cをペンチなどで切り取って切欠部1dを形成した後、ベース1を取り付けるべき天井や壁面に設置する。次に、本体3すなわち警報器本体2の刃部3bとベース1の刃受部1bとを周方向でずらした状態で筒部3aをベース1側の筒部1aに嵌合させ、その状態から刃部3bと刃受部1bとが係合する方向に警報器本体2をベース1に対し相対回動させる。これにより、警報器本体2がベース1にツイストロックされる。次いで、ベース1との嵌合部の外方より切欠部1d内にロックねじ7を挿入し、警報器本体2側の螺着部8に螺着する。
Next, a procedure for installing the fire alarm device of the present embodiment on a ceiling or a wall surface will be described.
When it is desired to prevent the alarm device body 2 from dropping off or due to artificial theft due to an earthquake or the like, first the base 1 should be attached after the thin portion (or notch) 1c of the base 1 is cut with pliers or the like to form the notch 1d. Install on the ceiling or wall. Next, the cylindrical portion 3a is fitted to the cylindrical portion 1a on the base 1 side in a state where the blade portion 3b of the main body 3, that is, the alarm device main body 2 and the blade receiving portion 1b of the base 1 are shifted in the circumferential direction. The alarm main body 2 is rotated relative to the base 1 in the direction in which the blade portion 3b and the blade receiving portion 1b are engaged. Thereby, the alarm body 2 is twist-locked to the base 1. Next, the lock screw 7 is inserted into the cutout portion 1d from the outside of the fitting portion with the base 1, and is screwed to the screwing portion 8 on the alarm device body 2 side.

これにより、ベース1の切欠部1dのエッジがロックねじ7の頭部と係合可能となり、警報器本体2の回動が阻止されるので、ツイストロック状態を解除できなくなる。このため、地震等による警報器本体2の脱落や作為的な盗難を防止することができる。
なお、ロックねじ7の配置は、警報器本体2の外周がベース1の筒部1aより大きいので、警報器本体2の陰にあり、外観の見映えを損なわない。
As a result, the edge of the notch 1d of the base 1 can be engaged with the head of the lock screw 7, and the rotation of the alarm main body 2 is prevented, so that the twist lock state cannot be released. For this reason, it is possible to prevent the alarm device body 2 from being dropped or artificially stolen due to an earthquake or the like.
The arrangement of the lock screw 7 is behind the alarm device body 2 because the outer periphery of the alarm device body 2 is larger than the cylindrical portion 1a of the base 1, and does not impair the appearance.

また、通常状態で使用できるように、つまり警報器本体2をベース1に対してツイストするだけで警報器本体2とベース1との係合や解除を簡単に行えるように火災警報器を天井や壁面へ設置するには、ベース1の薄肉部(又は切れ込み)1cを切り取らずに、ベース1を取り付けるべき天井や壁面に設置する。次いで、警報器本体2の刃部3bとベース1の刃受部1bとを周方向でずらした状態で筒部3aをベース1側の筒部1aに嵌合させ、その状態から係合方向に警報器本体2をツイストさせベース1にロックする。   In addition, the fire alarm can be installed on the ceiling so that it can be used in a normal state, that is, by simply twisting the alarm body 2 with respect to the base 1, the alarm body 2 and the base 1 can be easily engaged and released. In order to install on the wall surface, the base 1 is installed on the ceiling or wall surface to which the base 1 is to be attached without cutting off the thin portion (or cut) 1c of the base 1. Next, the cylindrical portion 3a is fitted to the cylindrical portion 1a on the base 1 side in a state where the blade portion 3b of the alarm device body 2 and the blade receiving portion 1b of the base 1 are shifted in the circumferential direction. The alarm body 2 is twisted and locked to the base 1.

これにより、従来同様、警報器本体2がベース1に相対回動可能にロックされるので、逆にロックを解除することも容易となる。このためこれまで通りの使い勝手の良い使用形態となって、機器交換等を容易に行うことができる。   Thereby, since the alarm device body 2 is locked to the base 1 so as to be capable of relative rotation as in the prior art, it is easy to release the lock. For this reason, it becomes an easy-to-use form of use as before, and device exchange etc. can be performed easily.

なお、ここではツイストロック嵌合部の刃部3bを本体3側に、刃受部1bをベース1側に、それぞれ配置したものを例に挙げて説明したが、これら刃部と刃受部の位置関係は逆でもよいことはいうまでもない。   In addition, although the blade part 3b of the twist lock fitting part has been described here as an example, and the blade receiving part 1b is arranged on the base 1 side, the blade part and the blade receiving part are described. Needless to say, the positional relationship may be reversed.

また、ここでは本体3に螺着部8を設けてロックねじ7を取り付け可能とするとともに、ベース1に切欠部1dを形成可能な薄肉部(又は切れ込み)1cを設けて、薄肉部(又は切れ込み)1cを切り欠いて切欠部1dを形成した際には、その切欠エッジがツイストロック状態下で螺着部8に螺着されるロックねじ7の頭部と係合可能となるように構成したものを例に挙げて説明したが、これら螺着部8と切欠部1d(薄肉部又は切れ込み1c)の位置関係も逆でよいことはいうまでもない。   In addition, here, the main body 3 is provided with a threaded portion 8 so that the lock screw 7 can be attached, and the base 1 is provided with a thin-walled portion (or notch) 1c capable of forming a notch 1d so that the thin-walled portion (or notch) is formed. ) When the cutout portion 1d is formed by forming the cutout portion 1c, the cutout edge can be engaged with the head of the lock screw 7 screwed into the screwing portion 8 under the twist lock state. Although the above has been described by way of example, it goes without saying that the positional relationship between the threaded portion 8 and the notched portion 1d (thin portion or notch 1c) may be reversed.
