Description

本発明は、天井材や壁材等の取付面に設置され、火災感知器を取り付けるための感知器ベースに関するものである。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sensor base which is installed on a mounting surface such as a ceiling material or a wall material and for mounting a fire sensor.

煙、熱、又は炎等を感知することにより火災を感知する火災感知器は、感知器ベースに取り付けられ、例えば天井面等に設置されている。感知器ベースには、その一部を設置面の取付穴に挿入して埋込設置する埋込型のものと、感知器ベースの大部分を天井面から露出させて設置する露出型のものがある。 A fire sensor that senses fire by sensing smoke, heat, flame, or the like is attached to a sensor base and installed, for example, on a ceiling surface. There are two types of sensor base: the embedded type, which is installed by inserting a part of the sensor base into the mounting hole on the installation surface, and the exposed type, which is installed with most of the sensor base exposed from the ceiling surface. be.

本発明は埋込型のものを対象としており、埋込型の例として、特許文献1に「感知器ベース」が開示されている。具体的には、「本実施形態の感知器10は、取付けプレート部11Bのねじ挿通穴11aを利用したネジ止め、またはネジ挿通孔11cと取付け金具を利用したネジ止めの何れかにより建造物の壁面への取付けが選択的に行える。」(特許文献1の0036段落参照)とあるように、埋込型の感知器ベースは、感知器ベースにおける火災感知器収容部分を天井等の取付面に埋め込む状態で設置されるものである。 The present invention is intended for the embedded type, and Patent Document 1 discloses a "sensor base" as an example of the embedded type. Specifically, "the sensor 10 of the present embodiment can be mounted on a building by either screwing using the screw insertion holes 11a of the mounting plate portion 11B, or by screwing using the screw insertion holes 11c and mounting brackets. Mounting to the wall surface can be selectively performed." (see paragraph 0036 of Patent Document 1), the embedded type sensor base has a fire sensor housing portion of the sensor base attached to a mounting surface such as a ceiling. It is installed in an embedded state.

感知器ベースに火災感知器を着脱させるとき、感知器ベースに設けられた端子と、火災感知器に設けられた端子とを噛み合わせるように、火災感知器を回転させながら取付けまたは取外しをする。このとき、埋込型の感知器ベースは、特許文献1のようにネジ止めではなく、感知器ベースに設けられた取付金具を用いて、天井材や壁材の取付面の裏側から圧接して取付面に設置されるものもある(特許文献2図1参照)。取付金具を用いる感知器ベースの場合、取付面と感知器ベース本体がネジなどによって位置固定されて設置されているのではないため、取付金具による取付面への係止状態が不十分であると、火災感知器着脱時の回転と同時に感知器ベースごと回転、つまり空転し、火災感知器の取付に時間を要する、また、火災感知器を確実に取付けられないといった課題がある。 When attaching/detaching the fire sensor to/from the sensor base, the fire sensor is attached/detached while being rotated so that terminals provided on the sensor base and terminals provided on the fire sensor are engaged with each other. At this time, the embedded type sensor base is not screwed as in Patent Document 1, but is pressed from the back side of the mounting surface of the ceiling material or wall material using a mounting bracket provided on the sensor base. Some are installed on the mounting surface (see FIG. 1 of Patent Document 2). In the case of a sensor base that uses mounting brackets, since the mounting surface and the sensor base body are not fixed with screws, etc., the locking state of the mounting brackets to the mounting surface is insufficient. However, when the fire sensor is attached and detached, the sensor base rotates at the same time, that is, it spins idle, and it takes time to attach the fire sensor, and the fire sensor cannot be securely attached.

本発明はかかる課題を解決するためになされたものであり、本発明に係る感知器ベースは、感知器ベースに火災感知器を着脱する時の回転と同時に感知器ベースごと回転しない、つまり空転しないものとすることで、火災感知器を短時間かつ確実に取付けることを可能とする感知器ベースを提供することを目的としている。 The present invention has been made to solve this problem, and the sensor base according to the present invention does not rotate together with the sensor base at the same time when the fire sensor is attached to or detached from the sensor base, that is, does not idle. It is an object of the present invention to provide a sensor base which enables a fire sensor to be mounted reliably in a short time.

(1)本発明に係る感知器ベースは、開口が設けられた設置面に設置されて、火災感知器を取り付けるためのものであって、
前記火災感知器が着脱可能に取り付けられ、円筒形をなす本体部と、該本体部から外周方向へ張出す鍔部と、該鍔部の背面に設けられ、弾性変形するシール部とを有し、
前記感知器ベースは、シール部を介して前記鍔部を前記設置面に圧接するようにして設置されることを特徴とするものである。
(2)また、上記(1)に記載のものにおいて、前記シール部は、環状に成形されることを特徴とするものである。
(1) A sensor base according to the present invention is installed on an installation surface provided with an opening for mounting a fire sensor,
The fire sensor is detachably attached, and has a cylindrical main body, a flange projecting from the main body in the outer peripheral direction, and an elastically deformable seal provided on the back surface of the flange. ,
The sensor base is installed such that the collar portion is pressed against the installation surface via a seal portion.
(2) Further, in the apparatus described in (1) above, the seal portion is formed in an annular shape.

本発明においては、感知器ベースを天井や壁材等の取付面に設置したとき、感知器ベースの鍔部背面側に設けられるシール部が、鍔部背面側と取付面との間で弾性変形し、圧接されることで取付面とシール部との摩擦により、感知器ベースの取付位置が動きにくくなり、火災感知器着脱時の火災感知器の回転動作に伴って、感知器ベースが一緒に回転することを防ぐことができるので、容易かつ確実に火災感知器の着脱を行うことができる。 In the present invention, when the sensor base is installed on a mounting surface such as a ceiling or wall material, the seal provided on the rear side of the flange of the sensor base is elastically deformed between the rear side of the flange and the mounting surface. However, the pressure contact causes friction between the mounting surface and the seal, making it difficult to move the mounting position of the sensor base. Since rotation can be prevented, the fire sensor can be attached and detached easily and reliably.

《Body part》
The main body 5 has a bottomed cylindrical shape with a bottom opening at the center. On the inner surface of the bottom portion of the body portion 5 (lower surface in the installed state), a blade receiving metal fitting is provided (not shown) that engages with the blade metal fitting provided on the fire sensor. Also, on the outer surface (upper surface in the installed state) of the bottom of the main body 5, a pair of mounting brackets 6 and a bracket mounting portion for mounting the sensor base 1 on the mounting surface 2 are positioned opposite to each other across an opening.

以上のように構成された本実施の形態の感知器ベース1を、設置面を天井としたときの設置方法について説明する。
はじめに、感知器ベース1および火災感知器を設置するための開口を取付面2に設ける。開口に向かって下方から感知器ベース1を挿入する。このとき開口は本体部5の外径よりも大きく、鍔部4の外径よりも小さい径で設けられるため、本体部5を開口に挿入すると、鍔部4の上面が取付面2と当接する位置で感知器ベース1は静止する。
具体的には、取付金具6をそれぞれ起立させた状態で感知器ベース1の本体部5を開口へ挿入し、鍔部4が取付面2に当接する位置で静止する。その静止状態で下方より、本体部5に設けられた取付金具用ねじ(図示なし)を回し、取付金具6をそれぞれ外周方向へ倒伏させるように下方へ移動させることで、取付面2は取付金具6と鍔部4とで挟持される。このとき、鍔部4の上面に設けられたパッキン7が押圧されて弾性変形するため、取付面2と感知器ベース1が密接し、感知器ベース1の取付位置から動きにくくなる状態で静止する。
A method of installing the sensor base 1 of the present embodiment configured as described above when the installation surface is a ceiling will be described.
First, an opening is provided in the mounting surface 2 for installing the sensor base 1 and the fire sensor. The sensor base 1 is inserted from below toward the opening. At this time, the opening is provided with a diameter larger than the outer diameter of the body portion 5 and smaller than the outer diameter of the flange portion 4, so that when the body portion 5 is inserted into the opening, the upper surface of the flange portion 4 contacts the mounting surface 2. At position the sensor base 1 is stationary.
Specifically, the body portion 5 of the sensor base 1 is inserted into the opening while the mounting brackets 6 are erected, and the flange portion 4 comes to rest at a position where it abuts against the mounting surface 2 . In this stationary state, the mounting bracket screws (not shown) provided on the main body 5 are turned from below to move the mounting brackets 6 downward so as to fall down in the outer peripheral direction. It is sandwiched between 6 and collar portion 4 . At this time, since the packing 7 provided on the upper surface of the collar portion 4 is pressed and elastically deformed, the mounting surface 2 and the sensor base 1 come into close contact with each other, and the sensor base 1 stops in a state where it is difficult to move from the mounting position. .

取付面2に設置された感知器ベース1に火災感知器を取り付ける場合、火災感知器に設けられた刃金具を、本体部5に設けられた刃受金具に係合させて取り付ける。このとき、刃金具と刃受金具を係合させるには火災感知器を捻るように回転させながら本体部5に取り付ける。
従来の感知器ベースでは、環状壁部の幅分でしか取付面に接地していないため、火災感知器の取付時の回転動作によって感知器ベースが滑ってしまい、感知器ベースの空転の原因となっていた。しかし、本実施の形態の感知器ベース1では、パッキン7が取付面2と圧接することで摩擦抵抗が大きくなるので、設置位置から動きにくくなり、火災感知器の取付時の回転動作による感知器ベース1の空転を防止することができる。
When the fire sensor is attached to the sensor base 1 installed on the mounting surface 2, the blade metal provided on the fire sensor is engaged with the blade receiving metal provided on the main body 5. At this time, in order to engage the blade metal fitting and the blade receiving metal fitting, the fire sensor is attached to the main body portion 5 while being rotated in a twisting manner.
With conventional detector bases, the base is only in contact with the mounting surface by the width of the annular wall, so the rotation of the fire detector during installation causes the base to slip, causing the base to spin. was becoming However, in the sensor base 1 of the present embodiment, the packing 7 is in pressure contact with the mounting surface 2 to increase the frictional resistance, making it difficult to move from the installation position. The idling of the base 1 can be prevented.
