Description

本発明は、ホームセキュリティシステムの侵入者検知器や、火災検知器に関するものであり、特に、電池にて駆動され、外部機器との間の配線を要しない検知器の取り付け機構に関するものである。 The present invention relates to an intruder detector and a fire detector of a home security system, and more particularly to a detector mounting mechanism that is driven by a battery and does not require wiring between external devices.

ホームセキュリティシステムは、システムの中心となるコントローラと、各種検知器とで構成されており、検知信号の伝送には、電波を用いたワイヤレス方式が採用されている。検知器は、電池を内蔵しており、しかも小型化が要求されているので、天井取り付け型検知器、壁面取り付け型検知器として、それぞれ専用の形状のものが実用化されている。一般には、天井に取り付ける場合が多いため、天井に固定して用いることを前提とした検知器が多い。例えば、物体が放射する赤外線エネルギーを検出して侵入者を検知する受動型赤外線検知器（いわゆるパッシブセンサ）は、円盤状のベース部分と、ドーム型をした本体とで構成され、その取り付け方法は、先に、天井にベース部分をネジ止めにより固定し、そのベース部分に、あとから本体を固定する形態となっている。このような天井取り付け専用型検知器は、天井が非常に高い室内などにおいては、壁面に取り付けて使用することになるが、そのまま壁面に取り付けると、検知ゾーンの方向（赤外線エネルギーを検出することの可能な方向）を適切に設定することができない。このような状態をさけるため、ベース部分が上面となる姿勢を維持させながら壁面に固定することになる。このような取付を実現させる器具として、天井・壁面兼用取り付け具（例えば、特許文献１参照。）が存在する。
実用新案登録第２６０５０２６号公報 The home security system is composed of a controller that is the center of the system and various detectors, and a wireless system using radio waves is adopted for transmission of detection signals. Since the detector has a built-in battery and is required to be downsized, a dedicated sensor has been put to practical use as a ceiling-mounted detector and a wall-mounted detector. In general, since there are many cases where the detector is mounted on the ceiling, many detectors are assumed to be fixed to the ceiling. For example, a passive infrared detector (so-called passive sensor) that detects intruders by detecting infrared energy radiated from an object is composed of a disk-shaped base portion and a dome-shaped main body. First, the base portion is fixed to the ceiling by screwing, and the main body is fixed to the base portion later. Such a ceiling-mounted type detector is used by attaching it to a wall surface in a room where the ceiling is very high, etc., but if it is attached to the wall surface as it is, the direction of the detection zone (which detects infrared energy) The possible direction) cannot be set properly. In order to avoid such a state, the base portion is fixed to the wall surface while maintaining the posture of the upper surface. As a tool for realizing such attachment, there is a ceiling / wall-use attachment (see, for example, Patent Document 1).
Utility Model Registration No. 26005026

天井取り付け専用型検知器を壁面に取り付けるためには、天井・壁面兼用取り付け具を用いなければならず、その器具の分だけコストがかかる。また、天井・壁面兼用取り付け具を、天井取り付け専用型検知器と壁面との間に介在させて取り付けることになり、その分の作業量も増える。天井・壁面兼用取り付け具は、各種の天井取り付け型検知器、壁面取り付け型検知器に幅広く対応させてあるため、形状が大きくなっており、設置後の外見において問題があった。 In order to attach the ceiling-mounted type detector to the wall surface, it is necessary to use a ceiling / wall surface mounting tool, which is expensive. In addition, the ceiling / wall surface mounting fixture is attached between the ceiling mounting type detector and the wall surface, which increases the amount of work. Since the ceiling / wall mounting fixture is widely compatible with various types of ceiling-mounted detectors and wall-mounted detectors, it has a large shape and has a problem in appearance after installation.

検知器取り付け面に、その外周部に設けたヒンジを介して開閉する板状の取り付けベースを備え、取り付けベースには、施工用のネジ穴を設けた。取り付けベースと検知器取り付け面との間には、取り付けベースを閉じた状態、取り付けベースを開いた状態のどちらの状態においても固定することのできる、固定機構を設けた。 The detector mounting surface is provided with a plate-shaped mounting base that opens and closes via a hinge provided on the outer peripheral portion thereof, and a screw hole for construction is provided in the mounting base. A fixing mechanism is provided between the mounting base and the detector mounting surface so that the mounting base can be fixed in either the closed state or the opened state.

天井に取り付けるときも、壁面に取り付けるときも、本体に一体化された取り付けベースを用いて固定することができ、取り付け場所に合わせて、天井・壁面兼用取り付け具を用意する必要性がなくなる。取り付けベースを、天井あるいは壁面にネジ止めし、その検知器の基本的な取り付け姿勢に合わせて、取り付けベースを閉じた状態、あるいは取り付けベースを開いた状態のどちらかの状態にして固定するだけで済むので、取り付け作業が簡略化される。壁面に固定した状態では、取り付けベースが露出することになるが、検知器は人間の身長よりも高いところに取り付けられるので、取り付けベースの大部分は検知器本体に隠れる形となり、外見上の違和感はなくなる。 Whether it is attached to the ceiling or the wall surface, it can be fixed using an attachment base integrated with the main body, eliminating the need to prepare a ceiling / wall mounting fixture in accordance with the installation location. Simply screw the mounting base to the ceiling or wall and fix it with the mounting base closed or the mounting base open according to the basic mounting orientation of the detector. As a result, installation work is simplified. When fixed to the wall, the mounting base is exposed, but the detector is mounted higher than the height of the person, so most of the mounting base is hidden by the detector body, making it look strange. Will disappear.

図１は、本発明の検知器の側面図であり、天井面に取り付ける直前の状態を示した図である。検知器の本体１と、取り付けベース２は、ヒンジ３で結合されており、取り付けベース２は、本体１からヒンジ３の回転軸を中心として分離した（開いた）状態である。天井面にこの検知器を取り付ける際には、図に示すように本体１をぶら下げた状態にし、取り付けベース２を天井面に固定する。取り付けベース２には、施工用のネジ穴５が設けられており、取り付けネジ４をこのネジ穴に通して固定する。 FIG. 1 is a side view of the detector of the present invention, showing a state immediately before being attached to a ceiling surface. The main body 1 of the detector and the mounting base 2 are coupled by a hinge 3, and the mounting base 2 is separated (opened) from the main body 1 around the rotation axis of the hinge 3. When this detector is attached to the ceiling surface, the main body 1 is suspended as shown in the figure, and the attachment base 2 is fixed to the ceiling surface. The mounting base 2 is provided with a screw hole 5 for construction, and the mounting screw 4 is fixed through the screw hole.

図２は、取り付けベース２を天井面に固定し、本体１を、取り付けベース２に固定した状態を示した図である。取り付けベース２を天井面に固定した後、本体１をヒンジ３の回転軸を中心として回転させ結合させた（閉じた）状態である。本体１が取り付けベース２から離れて、落下しないように、本体と取り付けベースの間には、固定機構（図示省略）が設けてられている。Ｚは、この検知器の検知範囲を示しており、立体警戒型のパッシブセンサの場合には、扇状に左右９０度、上下５０度前後の広がりをもったものとなっている。 FIG. 2 is a view showing a state in which the mounting base 2 is fixed to the ceiling surface and the main body 1 is fixed to the mounting base 2. After the attachment base 2 is fixed to the ceiling surface, the main body 1 is rotated around the rotation axis of the hinge 3 to be coupled (closed). A fixing mechanism (not shown) is provided between the main body and the mounting base so that the main body 1 does not fall off the mounting base 2. Z indicates the detection range of the detector, and in the case of a three-dimensional warning type passive sensor, the fan has a fan-like shape with a left and right extension of 90 degrees and a vertical extension of about 50 degrees.

図３は、本発明の検知器を壁面に取り付けるときの状態を示す説明図である。図３（ａ）は、壁面に取り付ける直前の状態を示した側面図であり、図３（ｂ）は、正面図である。取り付けベース２は、本体１からヒンジ３の回転軸を中心として開いた状態である。壁面にこの検知器を取り付ける際には、図に示すように、本体のドーム面が下方を向いた状態を保ちながら、取り付けベース２を壁面に固定する。取り付けベース２の施工用のネジ穴５に、取り付けネジ４を通して固定する。取り付けベース２を壁面に固定した後、本体１が、壁面から伝わる振動などにより揺れないように、本体と取り付けベースの間の固定機構によりロックする。この固定機構は、回転止め用スライドボス６を、図３（ｂ）に示す解放側（右側）から、固定側（左側）へスライドさせることにより作動する。回転止め用スライドボス６が固定側の位置にあるときは、本体１の上面が、この回転止め用スライドボス６に接触し、本体１の上方への回転が阻止され、回転止め用スライドボス６が解放側の位置にあるときは、本体１の上面に設けたボスの逃がし溝７に、この回転止め用スライドボス６が入り込み、取り付けベース２が閉じられるのである。 FIG. 3 is an explanatory view showing a state when the detector of the present invention is attached to the wall surface. Fig.3 (a) is the side view which showed the state just before attaching to a wall surface, and FIG.3 (b) is a front view. The mounting base 2 is in a state opened from the main body 1 around the rotation axis of the hinge 3. When this detector is attached to the wall surface, as shown in the figure, the attachment base 2 is fixed to the wall surface while keeping the dome surface of the main body facing downward. The mounting screw 4 is fixed through the mounting screw hole 5 of the mounting base 2. After fixing the mounting base 2 to the wall surface, the main body 1 is locked by a fixing mechanism between the main body and the mounting base so as not to be shaken by vibrations transmitted from the wall surface. This fixing mechanism operates by sliding the rotation-stopping slide boss 6 from the release side (right side) shown in FIG. 3B to the fixed side (left side). When the anti-rotation slide boss 6 is in the fixed position, the upper surface of the main body 1 comes into contact with the anti-rotation slide boss 6 to prevent the main body 1 from rotating upward, and the anti-rotation slide boss 6. Is in the release side position, the rotation-preventing slide boss 6 enters the boss escape groove 7 provided on the upper surface of the main body 1, and the mounting base 2 is closed.

検知器の検知範囲Ｚは、壁面に取り付けたときも、天井面に取り付けたときと同じ方向を向くようになる。このように、本発明の技術を採用することにより、天井取り付け型検知器、壁面取り付け型検知器といった取り付け位置の限定がなくなる。壁面に固定した状態では、取り付けベースが検知器本体から開かれた状態になるが、検知器は、高いところに取り付けられるので、取り付けベースの大部分は検知器本体に隠れる形となり、あまり目立つことはない。検知器取り付け面と、取り付けベースとの間の開き角を、任意の大きさのところで固定可能とすれば、傾斜した壁や天井にも取り付けることができる。検知範囲Ｚを水平方向に回転させることのできる機構を内蔵すれば、さらに取り付け位置の制約がなくなり扱いやすくなる。 The detection range Z of the detector is oriented in the same direction as when it is attached to the wall surface when it is attached to the ceiling surface. Thus, by adopting the technique of the present invention, there is no limitation on the mounting position such as a ceiling-mounted detector or a wall-mounted detector. When fixed to the wall, the mounting base is opened from the detector body, but the detector is mounted at a high place, so the majority of the mounting base is hidden by the detector body and is not very noticeable. There is no. If the opening angle between the detector mounting surface and the mounting base can be fixed at an arbitrary size, it can be mounted on an inclined wall or ceiling. If a mechanism capable of rotating the detection range Z in the horizontal direction is built in, it becomes easier to handle since there is no restriction on the mounting position.
