Description
【０００１】[0001]
本考案は、人体などの侵入による赤外線エネルギーを検知する検知装置に関し 、特に検知範囲が可変自在な検知装置に関するものである。 The present invention relates to a detection device for detecting infrared energy caused by intrusion of a human body, and more particularly to a detection device having a variable detection range.
【０００２】[0002]
従来、人体などの侵入による赤外線エネルギーを検知する検知装置は、図５に 示すように、検知素子１５の検知面１５ａ側に窓部１３ａａを設け、この窓部１ ３ａａに赤外線エネルギーを集光するフレネルレンズ１４などが配設されている 。 そして、前記検知素子１５が検知する検知範囲内で、ある所望の範囲のみ検知 するため、また、天井，壁など取り付ける位置を変えた状態で検知範囲を可変さ せるために、フレネルレンズ１４の外側に不要な検知範囲を遮蔽するマスク片１ ６ｃを矢印方向に移動自在に設けていた。 Conventionally, a detection device for detecting infrared energy due to intrusion of a human body or the like has a window portion 13aa provided on the detection surface 15a side of the detection element 15 as shown in FIG. 5, and the infrared energy is condensed on the window portion 13aa. The Fresnel lens 14 and the like are provided. Then, in order to detect only a desired range within the detection range detected by the detection element 15 and to change the detection range while changing the mounting position such as the ceiling or the wall, the outside of the Fresnel lens 14 is detected. Further, a mask piece 16c that shields an unnecessary detection range is provided movably in the arrow direction.
【０００３】[0003]
しかしながら、本来検知装置は、天井，壁などに取り付ける為に小型，軽量が 好ましいが、上述した検知装置では、マスク片１６ｃを移動させる機構を別途検 知装置外部に設けた為に小型、軽量化できず、コストも掛かるという問題があっ た。また、検知装置を所望の位置に取り付け、マスク片１６ｃを設定した後に、 悪戯などでマスク片１６ｃの設定が外部から容易に変えられる事を防ぐ為に固定 機構を設けたとしても、機構が複雑になり同様の問題があった。 However, the detector is originally preferably small and lightweight for mounting on the ceiling, wall, etc. However, in the above-mentioned detector, a mechanism for moving the mask piece 16c is separately provided outside the detector so that the detector is small and lightweight. There was a problem that it could not be done and the cost was high. In addition, even if a fixing mechanism is provided to prevent the setting of the mask piece 16c from being easily changed from the outside by a mischief or the like after the detection device is mounted at a desired position and the mask piece 16c is set, the mechanism is complicated. There was a similar problem.
【０００４】 そこで本考案は、上記問題点を解消するために、人体などの侵入による赤外線 エネルギーを検知する検知範囲を、ある所望の範囲のみ検知することができる機 構を備え、この機構を簡単に構成でき、小型，軽量な検知装置を提供することを 目的としている。In order to solve the above problems, the present invention is provided with a mechanism capable of detecting only a desired range of detection range of infrared energy due to intrusion of a human body or the like, and this mechanism is simple. The objective is to provide a compact and lightweight detection device that can be configured as described above.

次に、上記の目的を達成するための手段を、実施例に対応する図１乃至図３を 参照して説明する。 検知装置本体１の基部をなすシャーシ２に取り付けられ、球体を構成する検知 部３と、該検知部３の底面側に穿設され、赤外線エネルギーを集光する集光手段 ４が設けられた窓部３ａａと、前記検知部３の内部に回動自在に取り付けられた 円盤状の基板６と、該基板６の中央部に検知面５ａを前記窓部に向けて配設され た検知素子５と、前記検知部３の内壁と沿って前記基板６の外縁に一体形成され たマスク片６ｃとを具備したことを特徴としている。 Next, means for achieving the above object will be described with reference to FIGS. 1 to 3 corresponding to the embodiment. A window that is attached to a chassis 2 that forms the base of the detection device body 1 and that has a detection unit 3 that forms a sphere, and a light collection unit 4 that is provided on the bottom side of the detection unit 3 and that collects infrared energy. A portion 3aa, a disc-shaped substrate 6 rotatably attached to the inside of the detection unit 3, and a detection element 5 disposed in the center of the substrate 6 with a detection surface 5a facing the window. And a mask piece 6c integrally formed on the outer edge of the substrate 6 along the inner wall of the detection unit 3.
【０００６】 また、前記検知装置は、前記基板６の中央上面側に突出して設けられ、前記基 板６の回動を検知装置本体１の取り付け面側にて操作する操作レバー６ｂと、該 操作レバー６ｂに嵌合して基板６の回動を所定方向に案内する切欠き溝３ｂａと した構成としても良い。Further, the detection device is provided so as to project toward the central upper surface side of the substrate 6, and an operation lever 6 b for operating the rotation of the base plate 6 on the mounting surface side of the detection device main body 1, and the operation lever 6 b. It may be configured as a notch groove 3ba which is fitted to the lever 6b and guides the rotation of the substrate 6 in a predetermined direction.
【０００７】[0007]
基板６は球体状の検知部３内で回動自在であり、この回動により基板６に設け られた検知素子５の検知範囲は、基板６の外縁に一体形成されたマスク片６ｃに よって窓部３ａａが遮蔽されて可変自在である。 The substrate 6 is rotatable within the spherical detection unit 3, and the detection range of the detection element 5 provided on the substrate 6 by this rotation is controlled by the mask piece 6c integrally formed on the outer edge of the substrate 6 to open the window. The portion 3aa is shielded and can be freely changed.

図１は検知装置本体の平面図、図２は図１におけるＡ−Ａ線断面図、図３は図 １におけるＢ−Ｂ線断面図、図４はマスク片による遮蔽範囲の一例を示す窓部の 底面図である。 本実施例における検知装置は、天井，壁などの取り付け面に固着される図示し ない取り付け部に検知装置本体１が着脱自在な状態で取り付けられる。 図１，図２および図３に示すように、検知装置本体１は、シャーシ２と、検知 部３とで大略構成されている。 前記シャーシ２は、円形の小鉢状に形成されており、底面の中央部には、円形 の貫通穴２ａが形成されている。 1 is a plan view of the main body of the detection device, FIG. 2 is a cross-sectional view taken along the line AA in FIG. 1, FIG. 3 is a cross-sectional view taken along the line BB in FIG. 1, and FIG. FIG. In the detection device of this embodiment, the detection device main body 1 is detachably attached to a mounting portion (not shown) fixed to a mounting surface such as a ceiling or a wall. As shown in FIG. 1, FIG. 2 and FIG. 3, the detection device main body 1 is roughly composed of a chassis 2 and a detection portion 3. The chassis 2 is formed in a circular small bowl shape, and a circular through hole 2a is formed in the center of the bottom surface.
【０００９】 次に、検知部３は、前記貫通穴２ａ上に配置されており、貫通穴２ａの直径よ りも、やや大き目の直径を有した球状に形成されている。また、この検知部３は 、中央部分より上下に２分割されていて、下半球３ａの底面側には、図１に示す 円形の窓部３ａａが形成されており、この窓部３ａａには後述する検知素子５の 検知面５ａに赤外線エネルギーを集光するフレネルレンズ４が配設されている。 そして、前記下半球３ａの内壁の図１および図２に示すｙ軸方向の左右両側には 、検知部３の中心Ｏに対して点対称に円柱状の凸部３ａｂが形成されている。 さらに、上半球３ｂには、上部中央から図中ｘ軸方向に細長の切欠き溝３ｂａ が形成されている。Next, the detection unit 3 is arranged on the through hole 2a and is formed in a spherical shape having a diameter slightly larger than the diameter of the through hole 2a. Further, the detection unit 3 is divided into upper and lower parts from the central portion, and a circular window portion 3aa shown in FIG. 1 is formed on the bottom surface side of the lower hemisphere 3a, and this window portion 3aa will be described later. The Fresnel lens 4 for condensing infrared energy is arranged on the detection surface 5a of the detection element 5. Then, on the left and right sides of the inner wall of the lower hemisphere 3a in the y-axis direction shown in FIGS. 1 and 2, cylindrical convex portions 3ab are formed point-symmetrically with respect to the center O of the detection unit 3. Further, in the upper hemisphere 3b, an elongated notch groove 3ba is formed from the center of the upper part in the x-axis direction in the drawing.
【００１０】 また、前記検知部３の中心Ｏには、検知素子５が検知面５ａを底面側に向けた 状態で円盤形状の基板６の中央に取り付けられて配設される。 そして、図２に示すように、この基板６のｙ軸方向の左右両側における検知素 子５の位置部分には、突出片６ａが底面側に向け突出形成されている。該突出片 ６ａには、検知部３の中心Ｏに対する点対称の位置に円形の小孔６ａａが形成さ れている。 さらに、前記基板６の上側の中心には、円柱形状の操作レバー６ｂが突出形成 されている。 また、図３に示すように、前記基板６のｘ軸方向の左右両側には、検知部３の 内壁に沿って基板６から窓部３ａａの縁に掛けてマスク片６ｃが一体形成されて いる。このマスク片６ｃは、図示の如く検知部３（上半球３ｂ，下半球３ａ，窓 部３ａａ）が形成する球体の内部に、やや小形の球体の一部を構成して、これら が検知部３の内壁面に沿っている。Further, at the center O of the detecting portion 3, the detecting element 5 is attached and arranged at the center of the disk-shaped substrate 6 with the detecting surface 5a facing the bottom surface side. Then, as shown in FIG. 2, projecting pieces 6a are formed so as to project toward the bottom side at the position portions of the detection element 5 on both the left and right sides of the substrate 6 in the y-axis direction. A circular small hole 6aa is formed in the protruding piece 6a at a position symmetrical with respect to the center O of the detecting portion 3. Further, a columnar operation lever 6b is formed at the center of the upper side of the substrate 6 so as to project. Further, as shown in FIG. 3, mask pieces 6c are integrally formed on the left and right sides of the substrate 6 in the x-axis direction along the inner wall of the detection unit 3 from the substrate 6 to the edge of the window 3aa. .. The mask piece 6c constitutes a part of a slightly small sphere inside the sphere formed by the detection unit 3 (the upper hemisphere 3b, the lower hemisphere 3a, and the window 3aa) as shown in the drawing. Along the inner wall surface of.
【００１１】 しかして、検知部３の下半球３ａに形成された凸部３ａｂは、前記基板６の突 出片６ａに形成された小孔６ａａに回動自在に軸支されている。また、上半球３ ｂは、下半球３ａにとりつけられる。そして、基板６の操作レバー６ｂは、切欠 き溝３ｂａを嵌通して検知部３の上側に突出する。さらに、検知部３は、窓部３ ａａを下方に向けて前記シャーシ２の貫通穴２ａに嵌合する。 この結果、操作レバー６ｂは、切欠き溝３ｂａによってその移動が図１に示す ｘ軸方向のみの回動に規制され、操作レバー６ｂを切欠き溝３ｂａに沿って移動 されることで、基板６に一体形成されたマスク片６ｃによって窓部３ａａが遮蔽 され、不要な検知範囲を遮蔽し、所望の検知範囲のみを得ることができる。The convex portion 3ab formed on the lower hemisphere 3a of the detecting portion 3 is rotatably supported by the small hole 6aa formed on the protruding piece 6a of the substrate 6. The upper hemisphere 3b is attached to the lower hemisphere 3a. Then, the operation lever 6b of the substrate 6 is fitted into the notch groove 3ba and protrudes above the detection unit 3. Further, the detection unit 3 fits into the through hole 2a of the chassis 2 with the window 3aa facing downward. As a result, the movement of the operation lever 6b is restricted to the rotation only in the x-axis direction shown in FIG. 1 by the cutout groove 3ba, and the operation lever 6b is moved along the cutout groove 3ba, whereby the substrate 6 is moved. The window portion 3aa is shielded by the mask piece 6c integrally formed with the window portion 3a, so that an unnecessary detection area can be shielded and only a desired detection area can be obtained.
【００１２】 すなわち、図４に示すように、窓部３ａａは、操作レバー６ｂを図３に於ける Ｌ方向に操作したときに斜線部分が遮蔽され、Ｒ方向に操作したときには反対方 向が遮蔽される。 そして、基板６を回動させて窓部３ａａを遮蔽して検知範囲を可変した場合に おいても、検知素子５は常に中心Ｏに位置し、検知素子５とフレネルレンズ４と の間隔を常に一定間隔とすることができ検知を安定化できる。That is, as shown in FIG. 4, when the operation lever 6b is operated in the L direction in FIG. 3, the hatched portion of the window 3aa is shielded, and when operated in the R direction, the opposite direction is shielded. To be done. Even when the substrate 6 is rotated to block the window 3aa to change the detection range, the detection element 5 is always located at the center O, and the distance between the detection element 5 and the Fresnel lens 4 is always kept. The intervals can be set to be constant and the detection can be stabilized.
【００１３】 したがって、上述した実施例では、検知部３の上半球３ｂ上側に突出した操作 レバー６ｂを切欠き溝３ｂａに沿って移動することにより検知範囲を可変させる ことができる。また、窓部３ａａを遮蔽する機構を検知部３の内部に配設したこ とで、検知範囲の可変後に検知装置外部から操作されるのを防止することができ る。 そして、切欠き溝３ｂａの周辺に目盛りを設けることで所定の取り付け位置に 対して個人差なく検知範囲の可変を行うことができる。Therefore, in the above-described embodiment, the detection range can be varied by moving the operation lever 6b protruding above the upper hemisphere 3b of the detection unit 3 along the cutout groove 3ba. Further, by disposing the mechanism that shields the window portion 3aa inside the detection unit 3, it is possible to prevent the operation from outside the detection device after the detection range is changed. By providing a scale around the cutout groove 3ba, the detection range can be varied with respect to a predetermined mounting position without individual differences.
【００１４】 ところで、上述した実施例では、窓部３ａａが円形に形成され、基板６を一定 方向に軸支する構造としたが、基板６を軸支せず検知部３内で回動自在にし、用 途に合わせて切欠き溝３ｂａの形状、または窓部３ａａやマスク片６ｃの形状を 変更することにより、検知範囲の可変方法や形状を変えることができる。 また、検知部３の下半球３ａは、シャーシ２と一体に形成した構成であっても 良い。By the way, in the above-described embodiment, the window portion 3aa is formed in a circular shape to support the substrate 6 in a fixed direction. However, the substrate 6 is not pivotally supported but is rotatable within the detection unit 3. By changing the shape of the cutout groove 3ba or the shape of the window 3aa or the mask piece 6c according to the purpose, the method of changing the detection range and the shape can be changed. Further, the lower hemisphere 3a of the detection unit 3 may be formed integrally with the chassis 2.

以上説明したように本考案による検知装置は、基板には検知素子，マスク片が 設けられ、この基板が固定の本体に対し回動自在な構成としたので、構成を簡単 にできるとともに、検知装置の小型，軽量化を図ることができるという効果があ る。 As described above, in the detection device according to the present invention, the substrate is provided with the detection element and the mask piece, and the substrate is rotatable with respect to the fixed main body. It has the effect that it can be made smaller and lighter.
