Abstract

A clip (40) for detecting breakage of window glass which can open and close an opening in a vehicle. The clip (40) holds an end of the window glass (5), and when the window glass (5) breaks, the clip (4) crushes the end of the window glass (5) and detects the breakage of the window glass (5). The clip (40) has a first section (41) and a second section (42) which are formed by bending a steel plate for blade spring and face each other. The window glass (5) is located between the first and second sections (41, 42) which are urged in the direction of approaching each other while being in contact with the window glass (5) at positions shifted from each other. When the window glass (5) breaks, even if it does not break completely leaving a part of the glass remaining in place, the clip can reliably detect the breakage.

Description

ウィンドウガラス破損検出具Window glass breakage detector
　本発明は、ウィンドウガラス破損検出具に関するものである。 The present invention relates to a window glass breakage detector.
　特許文献１は、盗難防止のために車両のウィンドウガラスの割れを検知する装置を開示している。この装置においては、図１に示すように、ウィンドウガラス２００が窓開口部が閉止された全閉位置にあるときに、ウィンドウガラス２００を支持するケーブル式ウィンドウレギュレータ２１０のキャリアプレート２１１をウィンドウガラス２００の閉止方向に付勢する圧縮コイルばね２２０が設けられている。ウィンドウガラス２００が破損したときに、ウィンドウガラス２００に設けられたストッパピン２０５と車体側の係止部２０６とによる規制が解除され、圧縮コイルばね２２０がキャリアプレート２１１をウィンドウガラス２００の全閉位置よりも閉止側に移動させることとなり、リミットスイッチ２３０がこれを検出してウィンドウガラス２００の破損を検出する。 Patent Document 1 discloses a device that detects the breakage of a window glass of a vehicle to prevent theft. In this apparatus, as shown in FIG. 1, when the window glass 200 is in the fully closed position where the window opening is closed, the carrier plate 211 of the cable type window regulator 210 that supports the window glass 200 is attached to the window glass 200. A compression coil spring 220 is provided for biasing in the closing direction. When the window glass 200 is broken, the restriction by the stopper pin 205 provided on the window glass 200 and the locking portion 206 on the vehicle body side is released, and the compression coil spring 220 causes the carrier plate 211 to move to the fully closed position of the window glass 200. The limit switch 230 detects this and detects the breakage of the window glass 200.
　ウィンドウガラス２００には、通常、強化ガラスが用いられている。ウィンドウガラスに衝撃が加えられた場合、ウィンドウガラスは粉々に破損するようになっているが、その一部が粉砕せずに残ることがある。特に、キャリアプレート２１１付近にウィンドウガラス２００が残った場合、上記検出装置では、キャリアプレート２１１が閉止方向へ動かない時にはウィンドウガラス２００の破損が検出されないおそれがある。
特開平１１－３２１５６４号公報 As the window glass 200, tempered glass is usually used. When an impact is applied to the window glass, the window glass is broken in pieces, but a part of the window glass may remain without being crushed. In particular, when the window glass 200 remains in the vicinity of the carrier plate 211, the detection device may not detect breakage of the window glass 200 when the carrier plate 211 does not move in the closing direction.
Japanese Patent Laid-Open No. 11-321564
　本発明の目的は、ウィンドウガラスの破損に伴いウィンドウガラスが完全に粉砕せずに残るような場合でもウィンドウガラスの破損を確実に検出することができるウィンドウガラス破損検出具を提供することにある。 An object of the present invention is to provide a window glass breakage detection tool capable of reliably detecting breakage of a window glass even when the window glass remains without being completely pulverized due to breakage of the window glass.
　本発明の一態様によれば、ウィンドウガラス破損検出具が提供される。ウィンドウガラス破損検出具は、車両のウィンドウガラスに取り付けられ、ウィンドウガラスの破損に伴い当該ウィンドウガラスの一部領域を粉砕することによりウィンドウガラスの破損が検出される。該検出具は、ウィンドウガラスの面のずれた位置でウィンドウガラス面に接触する状態で、自身の弾性にて該ガラス面に対し互いに逆方向にウィンドウガラスを付勢する。 According to one aspect of the present invention, a window glass breakage detector is provided. The window glass breakage detector is attached to a window glass of a vehicle, and breakage of the window glass is detected by crushing a part of the window glass as the window glass breaks. The detector urges the window glass in directions opposite to each other with respect to the glass surface by its own elasticity while contacting the window glass surface at a position shifted from the surface of the window glass.
　これにより、ウィンドウガラスが破損すると、ウィンドウガラスの強度が低下することによって検出具が付勢力によりウィンドウガラスの一部領域を粉砕し、これによりウィンドウガラスの破損が検出される。よって、ウィンドウガラスの破損に伴いウィンドウガラスが完全に粉砕せずに残るような場合でもウィンドウガラスの破損を確実に検出することができる。 If the window glass is broken by this, the strength of the window glass is reduced, and the detection tool crushes a part of the window glass by the urging force, thereby detecting the breakage of the window glass. Therefore, even when the window glass remains without being completely pulverized due to the breakage of the window glass, the breakage of the window glass can be reliably detected.
　また、ウィンドウガラスの面でずれた位置で接触する状態で、検出具が自身の弾性にてガラス面に対しウィンドウガラスを互いに逆方向に付勢しているので、ウィンドウガラスの破損に伴ってウィンドウガラスを確実に粉砕してウィンドウガラスの破損を確実に検出することができる。 In addition, the detector urges the window glass against the glass surface in the opposite direction by its own elasticity while contacting at a position shifted on the surface of the window glass. The glass can be reliably crushed to detect the breakage of the window glass.
　本発明の別の態様によれば、ウィンドウガラス破損検出具が提供される。ウィンドウガラス破損検出具は、車両の開口部を開閉自在なウィンドウガラスでの端部においてウィンドウガラスを挟持して、ウィンドウガラスの破損に伴い当該ウィンドウガラスの端部を粉砕することによりウィンドウガラスの破損が検出される。該検出具は、板ばね用鋼板を折り曲げて形成された対向する第１部材と第２部材を有し、前記第１部材と第２部材は、それらの間に配置されたウィンドウガラスとウィンドウガラスの面でずれた位置で接触する状態で、互いに接近する方向に付勢されている。 According to another aspect of the present invention, a window glass breakage detector is provided. The window glass breakage detector breaks the window glass by holding the window glass at the end of the window glass that can be opened and closed freely and crushing the end of the window glass as the window glass breaks. Is detected. The detection tool has a first member and a second member facing each other formed by bending a steel plate for a leaf spring, and the first member and the second member are a window glass and a window glass disposed between them. In a state where they are in contact with each other at a position shifted on the surface, they are biased in a direction approaching each other.
　これにより、ウィンドウガラスが破損すると、ウィンドウガラスの強度が低下することによって検出具がその挟持力によりウィンドウガラスの端部を粉砕し、これによりウィンドウガラスの破損が検出される。よって、ウィンドウガラスの破損に伴いウィンドウガラスが完全に粉砕せずに残るような場合でもウィンドウガラスの破損を確実に検出することができる。また、ウィンドウガラスが全閉位置にないときも、ウィンドウガラスの破損を検出することができる。 If the window glass is broken by this, the strength of the window glass is reduced, and the detection tool crushes the edge of the window glass by its clamping force, thereby detecting the breakage of the window glass. Therefore, even when the window glass remains without being completely pulverized due to the breakage of the window glass, the breakage of the window glass can be reliably detected. Moreover, it is possible to detect breakage of the window glass even when the window glass is not in the fully closed position.
　また、対向する第１部材と第２部材部位は、それらの間に挟まれたウィンドウガラスに対し互いに接近する方向に付勢されるとともに、ウィンドウガラスの表面と裏面において違う場所でウィンドウガラスに対し力が加わっているので、ウィンドウガラスの破損に伴ってウィンドウガラスの端部を確実に粉砕してウィンドウガラスの破損を確実に検出することができる。 Further, the opposing first member and second member portions are urged in a direction approaching each other with respect to the window glass sandwiched between them, and at different locations on the front and back surfaces of the window glass. Since force is applied, it is possible to reliably detect the breakage of the window glass by reliably crushing the edge of the window glass as the window glass is broken.
　１実施形態において、第１部材と第２部材を連結する折り曲げ部は、二段に折り曲げられ、二段目の折り曲げ部の幅はウィンドウガラスの厚みよりも狭く、一段目の折り曲げ部においてウィンドウガラスの端面が接してよい。この構成により、板ばね用鋼板を折り曲げて対向させた部位においてウィンドウガラスの端部を確実に挟持することができる。 In one embodiment, the bent portion connecting the first member and the second member is bent in two steps, the width of the second bent portion is narrower than the thickness of the window glass, and the window glass in the first bent portion. The end faces of may be in contact. With this configuration, the end portion of the window glass can be securely clamped at a portion where the plate spring steel plate is bent and opposed.
　別の実施形態において、第１部材におけるウィンドウガラスとの接触部は、第２部材におけるウィンドウガラスとの接触部が挟まれるようにウィンドウガラスの面において２箇所に離間し、かつ、第１部材におけるウィンドウガラス５の両接触部を含む第１部材のウィンドウガラスと対向する部分は、第２部材におけるウィンドウガラス５との接触部の周りを包囲してよい。この構成により、第１部材において第２部材におけるウィンドウガラスとの接触部の周りにウィンドウガラスが当接している状態でウィンドウガラスが押圧されるので、ウィンドウガラスの端部を容易に粉砕して検出具を確実に落下させることができる。 In another embodiment, the contact portion with the window glass in the first member is spaced apart at two locations on the surface of the window glass so that the contact portion with the window glass in the second member is sandwiched, and in the first member The part facing the window glass of the first member including both contact parts of the window glass 5 may surround the contact part of the second member with the window glass 5. With this configuration, the window glass is pressed in the state where the window glass is in contact with the window glass in the first member around the contact portion of the second member, so that the edge of the window glass is easily crushed and detected. The tool can be dropped reliably.
　別の実施形態において、第１部材および第２部材の少なくとも一方は、前記ウィンドウガラスと突起にて接触する。この構成により、少ない力でウィンドウガラスを粉砕することができる。 In another embodiment, at least one of the first member and the second member is in contact with the window glass through a protrusion. With this configuration, the window glass can be crushed with a small force.
　別の実施形態において、検出具は車両の開口部を開閉自在なウィンドウガラスに取り付けられる。この構成により、ウィンドウガラスが全閉位置にないときも、ウィンドウガラスの破損を検出することができる。 In another embodiment, the detector is attached to a window glass that can freely open and close the opening of the vehicle. With this configuration, it is possible to detect breakage of the window glass even when the window glass is not in the fully closed position.
　別の実施形態において、検出具は、付勢用アーム部と、付勢用アーム部により連結された少なくとも一対の接触部とを備え、ウィンドウガラスの片面において少なくとも一対の接触部が、ウィンドウガラスの面でずれた位置で接触する状態で、ガラス面に対し互いに逆方向に付勢されていてもよい。 In another embodiment, the detection tool includes an urging arm part and at least a pair of contact parts connected by the urging arm part, and at least one pair of contact parts on one side of the window glass is made of the window glass. The glass surfaces may be biased in directions opposite to each other while being in contact with each other at a position shifted on the surface.

That is, the shaft 13 of the lift arm 12 of the window regulator 10 is supported on the base plate 11 fixed to the outdoor surface of the modular panel 6. An electric drive unit 14 is fixed to the base plate 11. As shown in FIG. 3, the lift arm 12 integrally has a sector gear 15 centered on a shaft 13, and the electric drive unit 14 shown in FIG. 2 includes a pinion 16 (FIG. 3) meshing with the sector gear 15 and its drive motor. (Not shown).
　図３において、リフトアーム１２の長さ方向の中間部分には、軸１７でイコライザアーム１８の中間部分が枢着されている。リフトアーム１２とイコライザアーム１８の上端部にはそれぞれ、ガイドピースすなわちローラ１９，２０が回転及び傾動可能に枢着されており、イコライザアーム１８の下端部には、ガイドピースすなわちローラ２１が枢着されている。 3, the intermediate portion of the equalizer arm 18 is pivotally attached to the intermediate portion in the length direction of the lift arm 12 by the shaft 17. Guide pieces, that is, rollers 19 and 20 are pivotally attached to the upper ends of the lift arm 12 and the equalizer arm 18, respectively, and a guide piece, that is, a roller 21 is pivotally attached to the lower ends of the equalizer arm 18. Has been.
　リフトアーム１２のガイドピース１９と、イコライザアーム１８のガイドピース２０とは、ウィンドウガラスブラケット２２に移動自在に嵌められ、イコライザアーム１８のガイドピース２１は、図２のモジュラーパネル６の室外側の面に固定された、イコライザアーム１８の姿勢を維持するレールであるイコライザアームブラケット２３に移動自在に案内される。 The guide piece 19 of the lift arm 12 and the guide piece 20 of the equalizer arm 18 are movably fitted to the window glass bracket 22, and the guide piece 21 of the equalizer arm 18 is the outer surface of the modular panel 6 in FIG. 2. It is guided to an equalizer arm bracket 23, which is a rail that maintains the posture of the equalizer arm 18 and is fixed to the arm.
　一方、ウィンドウガラス５の下縁にはウィンドウガラスホルダ２４が固定されている。ウィンドウガラスホルダ２４は、予めウィンドウガラス５の下縁に固定され、ウィンドウガラスホルダ２４を有するウィンドウガラス５が、アウタパネル２とインナパネル３の隙間に挿入されて、ボルト２５によりウィンドウガラスブラケット２２に固定されている。 On the other hand, a window glass holder 24 is fixed to the lower edge of the window glass 5. The window glass holder 24 is fixed to the lower edge of the window glass 5 in advance, and the window glass 5 having the window glass holder 24 is inserted into the gap between the outer panel 2 and the inner panel 3 and fixed to the window glass bracket 22 with bolts 25. Has been.
　図３に示すように、一対のガラスラン２６が立設されている。このガラスラン２６はゴム材よりなる。レール部材としての一対のガラスラン２６は、ウィンドウガラス５を移動自在に支持する。即ち、ウィンドウガラス５の前後の端部がガラスラン２６に案内されて上下に移動することができるようになっている。 As shown in FIG. 3, a pair of glass runs 26 are erected. The glass run 26 is made of a rubber material. A pair of glass run 26 as a rail member supports the window glass 5 movably. That is, the front and rear end portions of the window glass 5 are guided by the glass run 26 and can move up and down.
　図２の電動駆動ユニット１４を介してピニオン１６を正逆に駆動すると、セクタギヤ１５を介してリフトアーム１２が軸１３を中心に揺動し、その結果、ウィンドウガラスブラケット２２およびウィンドウガラス５が、イコライザアーム１８、ガイドピース１９，２０，２１、イコライザアームブラケット２３により略水平状態に保持されながら昇降する。このようなウィンドウガラス５の昇降により、車両の開口部４が開閉自在となっている。 When the pinion 16 is driven forward and backward via the electric drive unit 14 of FIG. 2, the lift arm 12 swings about the shaft 13 via the sector gear 15. As a result, the window glass bracket 22 and the window glass 5 are The equalizer arm 18, the guide pieces 19, 20, 21 and the equalizer arm bracket 23 are moved up and down while being held in a substantially horizontal state. By opening and lowering the window glass 5 as described above, the opening 4 of the vehicle can be freely opened and closed.
　図３の４－４線での縦断面を図４に示す。図４において、不正侵入防止用の開閉式ウィンドウガラスの破損検出装置３０が車両ドア１の内部に配置されている。破損検出装置３０はクリップ４０とセンサユニット６０を有している。 Fig. 4 shows a vertical section taken along line 4-4 of Fig. 3. In FIG. 4, an opening / closing type window glass breakage detection device 30 for preventing unauthorized entry is disposed inside the vehicle door 1. The breakage detection device 30 has a clip 40 and a sensor unit 60.
　図５は破損検出装置３０の斜視図を示す。図６Ａ－Ｃはクリップ４０を示し、図６Ａは正面図、図６Ｂは図６Ａの６Ｂ－６Ｂ線での断面図、図６Ｃは図６Ａの６Ｃ－６Ｃ線での断面図である。図７Ａ，Ｂは破損検出装置３０を示し、図７Ａは正面図、図７Ｂは図７Ａの７Ｂ－７Ｂ線での縦断面図である。 FIG. 5 is a perspective view of the damage detection device 30. 6A to 6C show the clip 40, FIG. 6A is a front view, FIG. 6B is a sectional view taken along line 6B-6B in FIG. 6A, and FIG. 6C is a sectional view taken along line 6C-6C in FIG. 7A and 7B show the breakage detection device 30, FIG. 7A is a front view, and FIG. 7B is a longitudinal sectional view taken along line 7B-7B in FIG. 7A.
　図４において、アウタパネル２とインナパネル３との間にウィンドウガラス５がウェザーストリップ７によりシールされた状態で配置されている。また、インナパネル３の内側にはドアトリム８が配置されている。クリップ４０はウィンドウガラス５の下端部に配置され、ウィンドウガラス５を挟んでいる。 In FIG. 4, the window glass 5 is disposed between the outer panel 2 and the inner panel 3 in a state of being sealed by a weather strip 7. A door trim 8 is disposed inside the inner panel 3. The clip 40 is disposed at the lower end of the window glass 5 and sandwiches the window glass 5.
　図６Ａ－Ｃに示すように、クリップ４０は、一枚の板ばね用鋼板を折り曲げて構成されている。クリップ４０は、対向する第１および第２部材４１，４２と部材４１，４２を連結する折り曲げ部４３とを有している。背面側の第１部材４１は長方形状をなし、正面側の第２部材４２は第１部材４１よりも幅狭な正方形状をなしている。第１部材４１と第２部材４２の間にウィンドウガラス５が配置され（図７Ａ，Ｂ参照）、第１部材４１と第２部材４２はウィンドウガラス５に対し互いに接近する方向に付勢されている。 As shown in FIGS. 6A to 6C, the clip 40 is formed by bending a single steel plate for a leaf spring. The clip 40 includes first and second members 41 and 42 that face each other and a bent portion 43 that connects the members 41 and 42. The first member 41 on the back side has a rectangular shape, and the second member 42 on the front side has a square shape that is narrower than the first member 41. The window glass 5 is disposed between the first member 41 and the second member 42 (see FIGS. 7A and 7B), and the first member 41 and the second member 42 are urged toward the window glass 5 toward each other. Yes.
　第１部材４１と第２部材４２を連結している折り曲げ部４３は、二段に折り曲げられ、一段目の折り曲げ部４３ａにおいてウィンドウガラス５の端面が接し、二段目の折り曲げ部４３ｂの幅はウィンドウガラス５の厚みよりも狭い（図７Ｂ参照）。つまり、クリップ４０の折り曲げ部４３は段差部を形成し、段差部に図７Ｂに示すようにウィンドウガラス５の端面が接しており、かつ、折り曲げ部４３の下辺部付近でウィンドウガラス５を挟み込まないようになっている。 The bent portion 43 connecting the first member 41 and the second member 42 is bent in two steps, the end surface of the window glass 5 is in contact with the first bent portion 43a, and the width of the second bent portion 43b is It is narrower than the thickness of the window glass 5 (see FIG. 7B). That is, the bent portion 43 of the clip 40 forms a stepped portion, the end surface of the window glass 5 is in contact with the stepped portion as shown in FIG. 7B, and the window glass 5 is not sandwiched near the lower side portion of the bent portion 43. It is like that.
　図６Ａにおいて、第１部材４１の中央部には長方形状の透孔４４が形成されている。透孔４４に対応する位置に第２部材４２が位置している。図６Ａ－Ｃに示すように、第１部材４１における左右の上隅には第２部材４２に向かって突出する突起４５が形成され、突起４５の先端は図７Ｂに示すようにウィンドウガラス５の裏面５ｂと接触している。第２部材４２は、図７Ａに示すように第１部材４１の透孔４４に対応する場所で、図７Ｂに示すようにウィンドウガラス５の表面５ａと接触している。よって、第１部材４１におけるウィンドウガラス５との接触部はウィンドウガラス５の面において２箇所に離間されており、第２部材４２におけるウィンドウガラス５との接触部がその間に位置し、かつ、第１部材４１におけるウィンドウガラス５との両接触部を含む第１部材４１のウィンドウガラス５と対向する部分は、第２部材４２におけるウィンドウガラス５との接触部の周りを包囲している。つまり、図７Ａに示すように第１部材４１におけるウィンドウガラス５と対向する部分は略Ｕ字状を有し、これによりウィンドウガラス５が破壊されるような形状をなし、ウィンドウガラス５を破壊した後に確実にクリップ４０を落下させることが可能となる。第２部材４２はウィンドウガラス５に接着されている。 6A, a rectangular through hole 44 is formed at the center of the first member 41. The second member 42 is located at a position corresponding to the through hole 44. As shown in FIGS. 6A to 6C, projections 45 projecting toward the second member 42 are formed at the left and right upper corners of the first member 41, and the tips of the projections 45 are formed on the window glass 5 as shown in FIG. 7B. It is in contact with the back surface 5b. The second member 42 is in contact with the surface 5a of the window glass 5 as shown in FIG. 7B at a location corresponding to the through hole 44 of the first member 41 as shown in FIG. 7A. Therefore, the contact portion with the window glass 5 in the first member 41 is separated at two places on the surface of the window glass 5, the contact portion with the window glass 5 in the second member 42 is located between them, and A portion of the first member 41 that includes both contact portions with the window glass 5 and faces the window glass 5 of the first member 41 surrounds the contact portion of the second member 42 with the window glass 5. That is, as shown to FIG. 7A, the part facing the window glass 5 in the 1st member 41 has a substantially U shape, and it made the shape by which the window glass 5 was destroyed by this, and the window glass 5 was destroyed. The clip 40 can be reliably dropped later. The second member 42 is bonded to the window glass 5.
　このようにして、ウィンドウガラス５が配置される第１部材４１と第２部材４２の間において第１部材４１と第２部材４２がウィンドウガラス５の面でずれた位置で接触する状態で、互いに接近する方向に付勢されている。即ち、ウィンドウガラス５の表面５ａと裏面５ｂにおいて違う場所でウィンドウガラス５に対し力が加えられる。また、クリップ４０はウィンドウガラス５の下端部を所定の力以上で挟持している。 In this way, the first member 41 and the second member 42 are in contact with each other at a position shifted on the surface of the window glass 5 between the first member 41 and the second member 42 where the window glass 5 is disposed. It is energized in the approaching direction. That is, force is applied to the window glass 5 at different locations on the front surface 5a and the back surface 5b of the window glass 5. The clip 40 holds the lower end of the window glass 5 with a predetermined force or more.
　図５，７Ａに示すように、クリップ４０の第２部材４２における正面には永久磁石５０が配置されている。
　センサユニット６０は、図４に示すように、インナパネル３に固定されている。ここで、鉛直方向をＸ方向とするとともに、水平方向をＹ方向とする。クリップ４０はＸ方向に移動、即ち、落下することになる。 As shown in FIGS. 5 and 7A, a permanent magnet 50 is disposed on the front surface of the second member 42 of the clip 40.
The sensor unit 60 is fixed to the inner panel 3 as shown in FIG. Here, the vertical direction is the X direction and the horizontal direction is the Y direction. The clip 40 moves in the X direction, that is, falls.
　センサユニット６０は、磁気センサ素子である第１の磁気センサ６１および第２の磁気センサ６２と、基板６３とを具備している。基板６３に第１の磁気センサ６１と第２の磁気センサ６２が上下に離間して配置されている。具体的には磁気センサ６１，６２は４ｃｍ程度離間している。第１の磁気センサ６１は、ウィンドウガラス５全閉時の磁石５０と同じ高さに配置され、かつ磁石５０に対しＹ方向に所定の距離だけ離間して配置されている。第２の磁気センサ６２は、第１の磁気センサ６１よりも下方に位置しており、クリップ４０の落下に伴い第２の磁気センサ６２の前を磁石５０が通過する。 The sensor unit 60 includes a first magnetic sensor 61 and a second magnetic sensor 62 which are magnetic sensor elements, and a substrate 63. A first magnetic sensor 61 and a second magnetic sensor 62 are spaced apart from each other on the substrate 63. Specifically, the magnetic sensors 61 and 62 are separated by about 4 cm. The first magnetic sensor 61 is disposed at the same height as the magnet 50 when the window glass 5 is fully closed, and is separated from the magnet 50 by a predetermined distance in the Y direction. The second magnetic sensor 62 is positioned below the first magnetic sensor 61, and the magnet 50 passes in front of the second magnetic sensor 62 when the clip 40 is dropped.
　各磁気センサ６１，６２は磁石５０との距離に応じた信号を出力する。図４の状態では、第１の磁気センサ６１は磁石５０と同じ高さに配置されているので、高出力であり、第２の磁気センサ６２は第１の磁気センサ６１よりも下方に位置しているので低出力である。磁気センサ６１，６２は例えばホールＩＣである。 Each magnetic sensor 61, 62 outputs a signal corresponding to the distance from the magnet 50. In the state of FIG. 4, the first magnetic sensor 61 is disposed at the same height as the magnet 50, so that the output is high, and the second magnetic sensor 62 is positioned below the first magnetic sensor 61. Therefore, it is low output. The magnetic sensors 61 and 62 are, for example, Hall ICs.
　磁気センサ６１，６２は図４に示すようにコントローラ７０に接続されている。コントローラ７０はＡ／Ｄ変換器やマイコンを具備しており、マイコンは磁気センサ６１，６２からの信号（デジタル出力値Ｖｓ１，Ｖｓ２）をＡ／Ｄ変換したものを取り込むことができ、さらに、マイコンは磁気センサ６１，６２の出力値を加算して図１２に示す出力信号の和（＝Ｖｓ１＋Ｖｓ２）を得る。これにより、図１１の各磁気センサ６１，６２の出力値Ｖｓ１，Ｖｓ２が単独で用いられる場合に比べ広範囲（図１２では８０ｍｍ）において出力レベルが高い信号が得られる。その結果、広範囲において磁石５０の位置を検出できる。図４において、コントローラ７０には警報装置７１が接続されている。 The magnetic sensors 61 and 62 are connected to the controller 70 as shown in FIG. The controller 70 includes an A / D converter and a microcomputer. The microcomputer can take in signals obtained by A / D conversion of signals (digital output values Vs1, Vs2) from the magnetic sensors 61, 62. Adds the output values of the magnetic sensors 61 and 62 to obtain the sum (= Vs1 + Vs2) of the output signals shown in FIG. As a result, a signal with a high output level can be obtained in a wider range (80 mm in FIG. 12) than when the output values Vs1 and Vs2 of the magnetic sensors 61 and 62 in FIG. 11 are used alone. As a result, the position of the magnet 50 can be detected in a wide range. In FIG. 4, an alarm device 71 is connected to the controller 70.
　次に、開閉式ウィンドウガラスの破損検出装置の作用、即ち、ウィンドウガラス５が壊されたときの動作を説明する。
　通常時、図７Ａ，Ｂに示すように、乗員が車両から離れるときにウィンドウガラス５は全閉または数ｃｍほど少し開いている。コントローラ７０は図１２のセンサ出力レベルからウィンドウガラス５の位置を検出しており、パーキングブレーキが操作されている時にウィンドウガラス５が全閉または数ｃｍ開いているとガラスの割れ検知モードを設定する。一方、ウィンドウガラス５の端部に配置されたクリップ４０がウィンドウガラス５の端部を挟持している。詳しくは、クリップ４０の自身の弾性力にて第１部材４１と第２部材４２との間にウィンドウガラス５を挟持している。また、センサユニット６０のセンサ６１の前方に磁石５０が位置している。 Next, the operation of the breakage detection device for the openable window glass, that is, the operation when the window glass 5 is broken will be described.
Normally, as shown in FIGS. 7A and 7B, when the occupant leaves the vehicle, the window glass 5 is fully closed or slightly opened by several centimeters. The controller 70 detects the position of the window glass 5 from the sensor output level of FIG. 12, and sets the glass breakage detection mode when the window glass 5 is fully closed or opened several cm when the parking brake is operated. . On the other hand, the clip 40 arranged at the end of the window glass 5 sandwiches the end of the window glass 5. Specifically, the window glass 5 is sandwiched between the first member 41 and the second member 42 by the elastic force of the clip 40 itself. Further, the magnet 50 is located in front of the sensor 61 of the sensor unit 60.
　この状態から、強化ガラスからなるウィンドウガラス５の一部が破損すると、図８Ａ，Ｂに示すようにウィンドウガラス５のすべてにひびが入り強度が著しく低下する。
　この強度低下に伴って図９Ａ，Ｂに示すようにクリップ４０がその挟持力によりウィンドウガラス５の下端部を粉砕する。つまり、クリップ４０のばね力によりウィンドウガラス５が部分的に完全に粉砕される。これにより、図１０Ａ，Ｂに示すように、矢印の方向にクリップ４０が落下する。 If a part of the window glass 5 made of tempered glass is broken from this state, as shown in FIGS. 8A and 8B, all the window glass 5 is cracked and the strength is remarkably lowered.
As the strength decreases, the clip 40 crushes the lower end portion of the window glass 5 by its clamping force as shown in FIGS. 9A and 9B. That is, the window glass 5 is partially and completely crushed by the spring force of the clip 40. Thereby, as shown to FIG. 10A, B, the clip 40 falls in the direction of the arrow.
　詳しくは、図８Ａ，Ｂに示すように、第２部材４２の付勢力によりウィンドウガラス５が押されてクリップ４０の第１部材４１に当接する。この状態で図９Ａ，Ｂに示すように、透孔４４の周りが支持された状態で第２部材４２によりウィンドウガラス５が押圧され、透孔４４におけるウィンドウガラス５が粉々に粉砕される。つまり、破壊されたウィンドウガラス５が逆Ｕ字形状になる。そして、図１０Ａ，Ｂに示すように、クリップ４０が落下する。 Specifically, as shown in FIGS. 8A and 8B, the window glass 5 is pushed by the urging force of the second member 42 and comes into contact with the first member 41 of the clip 40. In this state, as shown in FIGS. 9A and 9B, the window glass 5 is pressed by the second member 42 in a state where the periphery of the through hole 44 is supported, and the window glass 5 in the through hole 44 is crushed into pieces. That is, the broken window glass 5 has an inverted U shape. Then, as shown in FIGS. 10A and 10B, the clip 40 falls.
　センサユニット６０において、ウィンドウガラス５が破損される前においては磁気センサ６１，６２の出力信号の和（＝Ｖｓ１＋Ｖｓ２）は、所定の閾値以上の値を示すが、ウィンドウガラス５の破損に伴いクリップ４０が落下すると、磁気センサ６１，６２の出力信号の和が所定の閾値未満の値を示す。これにより、クリップ４０の落下が検出される。 In the sensor unit 60, before the window glass 5 is broken, the sum of the output signals of the magnetic sensors 61 and 62 (= Vs1 + Vs2) shows a value equal to or greater than a predetermined threshold value. Falls, the sum of the output signals of the magnetic sensors 61 and 62 indicates a value less than a predetermined threshold value. Thereby, the fall of the clip 40 is detected.
　このようにして、強化ガラスは一部が割れるとすべてにひびが入り強度が著しく低下する特徴を利用して未検知、誤検知を極力少なくすることができる。
　また、図３に示すように、ウィンドウガラス５が全閉位置にないときも、ウィンドウガラス５が破損するとクリップ４０が落下するため、ウィンドウガラス５の破損を検出することができる。詳しくは、特許文献１に示されているように、従来はウィンドウガラスの全閉時のウィンドウガラスの移動を検出していたためウィンドウガラスが全閉位置にないときはウィンドウガラスの破損を検出することができなかったが、本実施形態では換気等のためにウィンドウガラスを少し開けている場合のようにウィンドウガラスが全閉位置にないときもウィンドウガラスの破損を検出することができる。 In this way, if the tempered glass is partially broken, it can be cracked and the strength is remarkably reduced, so that undetected and erroneous detection can be minimized.
Further, as shown in FIG. 3, even when the window glass 5 is not in the fully closed position, the clip 40 is dropped when the window glass 5 is broken, so that the breakage of the window glass 5 can be detected. Specifically, as disclosed in Patent Document 1, conventionally, the movement of the window glass when the window glass is fully closed is detected, so that the window glass is detected to be broken when the window glass is not in the fully closed position. However, in this embodiment, breakage of the window glass can be detected even when the window glass is not in the fully closed position as in the case where the window glass is slightly opened for ventilation or the like.
　また、図７Ａ，Ｂのクリップ４０は、折り曲げられた板ばね用鋼板からなり、ウィンドウガラス５を挟持する、対向する第１部材４１と第２部材４２を有し、第１部材４１と第２部材４２はウィンドウガラス５の面でずれた位置で接触する状態で、互いに接近する方向に付勢されている。これにより、ウィンドウガラス５の表面５ａと裏面５ｂにおいて違う場所でウィンドウガラス５に対し力が加わっているので、ウィンドウガラス５の破損に伴ってウィンドウガラス５の端部を確実に粉砕してウィンドウガラス５の破損を確実に検出することができる。 Moreover, the clip 40 of FIG. 7A and B consists of the bent steel plate for leaf | plate springs, has the 1st member 41 and the 2nd member 42 which oppose and pinch | interpose the window glass 5, and the 1st member 41 and 2nd The members 42 are biased in a direction approaching each other in a state where they are in contact with each other at a position shifted on the surface of the window glass 5. As a result, a force is applied to the window glass 5 at different locations on the front surface 5a and the back surface 5b of the window glass 5, so that the end portion of the window glass 5 is surely pulverized as the window glass 5 is broken. 5 can be reliably detected.
　また、図７Ａ，Ｂのクリップ４０の第１部材４１におけるウィンドウガラス５との接触部は第２部材４２におけるウィンドウガラス５との接触部に対しウィンドウガラス５の面において離間し、かつ、第１部材４１におけるウィンドウガラス５との両接触部を含む第１部材４１のウィンドウガラス５と対向する部分は、第２部材４２におけるウィンドウガラス５との接触部の周りを包囲している。よって、図８Ａ，Ｂに示すように、第１部材４１において第２部材４２におけるウィンドウガラス５との接触部の周りにウィンドウガラス５が当接している状態においてウィンドウガラス５が押圧される。即ち、第１部材４１において、透孔４４の周りにおいてウィンドウガラス５を支持した状態で透孔４４の内部においてウィンドウガラス５が押圧される。これにより、図９Ａ，Ｂに示すように、ウィンドウガラス５の端部を容易に粉砕してクリップ４０を確実に落下させることができる。 Moreover, the contact part with the window glass 5 in the 1st member 41 of the clip 40 of FIG. 7A and B is spaced apart in the surface of the window glass 5 with respect to the contact part with the window glass 5 in the 2nd member 42, and is 1st. The portion of the member 41 that faces both the window glass 5 of the first member 41 including both contact portions with the window glass 5 surrounds the contact portion of the second member 42 with the window glass 5. Therefore, as shown in FIGS. 8A and 8B, the window glass 5 is pressed in the state where the window glass 5 is in contact with the first member 41 around the contact portion of the second member 42 with the window glass 5. That is, in the first member 41, the window glass 5 is pressed inside the through hole 44 in a state where the window glass 5 is supported around the through hole 44. As a result, as shown in FIGS. 9A and 9B, the end portion of the window glass 5 can be easily crushed and the clip 40 can be reliably dropped.
　図４において、センサユニット６０によってクリップ４０の落下を検出することによりウィンドウガラス５の破損が検出されると、コントローラ７０は警報装置７１を作動して警報を発する。 In FIG. 4, when the break of the window glass 5 is detected by detecting the fall of the clip 40 by the sensor unit 60, the controller 70 operates the alarm device 71 to issue an alarm.
　上記第１実施形態は、以下のような効果を奏する。
　（１）クリップ４０は、開閉式ウィンドウガラスの破損検出具として働く、つまり、クリップ４０は、車両の開口部４を開閉自在なウィンドウガラス５の端部を挟持して、ウィンドウガラス５の破損に伴って当該ウィンドウガラス５の端部を粉砕する。これが、開閉式ウィンドウガラスの破損を検出するために使用される。図７Ａ，Ｂに示すように、クリップ４０は、折り曲げられた板ばね用鋼板からなり、対向する第１部材４１と第２部材４２を有し、第１部材４１と第２部材４２は、それらの間に配置されたウィンドウガラス５とウィンドウガラス５の面でずれた位置で接触する状態で、互いに接近する方向に付勢されている。言い換えると、クリップ５は、自身の弾性にてウィンドウガラス５のガラス面５ａ，５ｂに対し互いに逆方向にウィンドウガラス５を付勢している。これにより、ウィンドウガラス５の破損に伴いウィンドウガラス５の端部を確実に粉砕してウィンドウガラス５の破損を確実に検出することができるとともに、ウィンドウガラス５が全閉位置にないときもウィンドウガラス５の破損を検出することができる。 The first embodiment has the following effects.
(1) The clip 40 functions as a breakage detection tool for an openable / closable window glass. In other words, the clip 40 sandwiches an end of the window glass 5 that can freely open and close the opening 4 of the vehicle, and breaks the window glass 5. At the same time, the end of the window glass 5 is crushed. This is used to detect breakage of the openable window glass. As shown in FIGS. 7A and 7B, the clip 40 is made of a bent steel plate for a leaf spring, and has a first member 41 and a second member 42 facing each other, and the first member 41 and the second member 42 are The window glass 5 disposed between the two and the window glass 5 is biased in a direction approaching each other in a state where they are in contact with each other at a position shifted on the surface of the window glass 5. In other words, the clip 5 urges the window glass 5 in the opposite directions to the glass surfaces 5a and 5b of the window glass 5 by its own elasticity. As a result, it is possible to reliably detect the breakage of the window glass 5 by reliably crushing the end portion of the window glass 5 in accordance with the breakage of the window glass 5, and even when the window glass 5 is not in the fully closed position. 5 breakage can be detected.
　詳しくは、図１の従来技術の検出装置がウィンドウガラス２００が全閉位置よりも閉止側に変位することを検出する構成では、ウィンドウガラス２００が全閉位置にないとき、即ち、換気のためにウィンドウガラス２００を少し開けていたときには、ウィンドウガラス２００の破損を検出することができなかった。これに対し、本実施形態においてはウィンドウガラス５が全閉位置にないときもウィンドウガラス５の破損を検出することができる。 Specifically, in the configuration in which the detection device of the prior art in FIG. 1 detects that the window glass 200 is displaced from the fully closed position to the closed side, when the window glass 200 is not in the fully closed position, that is, for ventilation. When the window glass 200 was opened a little, the breakage of the window glass 200 could not be detected. In contrast, in the present embodiment, breakage of the window glass 5 can be detected even when the window glass 5 is not in the fully closed position.
　（２）図７Ａ，Ｂに示すごとく、第１部材４１と第２部材４２を連結する折り曲げ部４３は、二段に折り曲げられ、二段目の折り曲げ部４３ｂの幅はウィンドウガラス５の厚みよりも狭く、一段目の折り曲げ部４３ａにおいてウィンドウガラス５の端面が接する。これにより、クリップ４０はウィンドウガラス５を折り曲げ部の下辺部付近のみで挟み込み、クリップ４０のウィンドウガラス５に対する挟持力が弱くなることがない。従って、折り曲げられた板ばね用鋼板からなる対向する第１部材４１および第２部材４２においてウィンドウガラス５の端部を確実に挟持することができる。 (2) As shown in FIGS. 7A and 7B, the bent portion 43 connecting the first member 41 and the second member 42 is bent in two steps, and the width of the second bent portion 43 b is larger than the thickness of the window glass 5. And the end face of the window glass 5 is in contact with the bent portion 43a of the first stage. As a result, the clip 40 sandwiches the window glass 5 only near the lower side of the bent portion, and the clamping force of the clip 40 to the window glass 5 is not weakened. Therefore, the edge part of the window glass 5 can be reliably clamped in the 1st member 41 and the 2nd member 42 which consist of the bent steel plate for leaf | plate springs.
　（３）図７Ａ，Ｂに示すごとく、第１部材４１におけるウィンドウガラス５との接触部はウィンドウガラス５の面において２箇所に離間されており、第２部材４２におけるウィンドウガラス５との接触部がその間に位置し、かつ、第１部材４１におけるウィンドウガラス５との両接触部を含む第１部材４１のウィンドウガラス５と対向する部分は、第２部材４２におけるウィンドウガラス５との接触部の周りを包囲している。これにより、図８Ａ，Ｂのごとく第１部材４１において第２部材４２におけるウィンドウガラス５との接触部の周りでウィンドウガラス５が当接している状態においてウィンドウガラス５が押圧されるので、ウィンドウガラス５の端部を容易に粉砕してクリップ４０を確実に落下させることができる（図９Ａ，Ｂ参照）。 (3) As shown in FIGS. 7A and 7B, the contact portion of the first member 41 with the window glass 5 is separated at two locations on the surface of the window glass 5, and the contact portion of the second member 42 with the window glass 5. Is located between them, and the portion of the first member 41 facing the window glass 5 including both contact portions with the window glass 5 is the portion of the second member 42 that is in contact with the window glass 5. Surrounds the surroundings. Accordingly, as shown in FIGS. 8A and 8B, the window glass 5 is pressed in a state where the window glass 5 is in contact with the window glass 5 around the contact portion of the second member 42 with the first member 41. 5 can be easily crushed and the clip 40 can be reliably dropped (see FIGS. 9A and 9B).
　（４）図７Ａ，Ｂに示すごとく、第１部材４１は、ウィンドウガラス５と突起４５にて接触している。これにより、ウィンドウガラス５にひびが入ると、少ない力でウィンドウガラス５を粉砕することができる。即ち、ウィンドウガラス５に効率的に力が掛かる。 (4) As shown in FIGS. 7A and 7B, the first member 41 is in contact with the window glass 5 at the protrusion 45. Thereby, if the window glass 5 is cracked, the window glass 5 can be crushed with a small force. That is, a force is efficiently applied to the window glass 5.
　（５）また、従来技術においてはレギュレータへの細工が必要であり、信頼性、品質が低下する可能性があるが、本実施形態ではレギュレータへの細工が不要であり、信頼性、品質に優れたものとすることができる。また、従来技術においては構造が複雑であるためコストアップを招きやすいが、本実施形態は構成が簡単であり、比較的安価に開閉式ウィンドウガラス破損検出装置を提供することができる。 (5) In addition, in the prior art, it is necessary to work on the regulator, and the reliability and quality may be reduced, but in this embodiment, the work on the regulator is not required, and the reliability and quality are excellent. Can be. Further, in the prior art, since the structure is complicated, the cost is likely to increase. However, the present embodiment has a simple configuration and can provide an openable / closable window glass breakage detection device at a relatively low cost.
　本実施形態は前記に限定されるものではなく、例えば、次のように具体化してもよい。
　（Ａ）Ｘアーム式ウィンドウレギュレータの代わりに、ウィンドウレギュレータはケーブル式ウィンドウレギュレータであってもよい。 The present embodiment is not limited to the above, and may be embodied as follows, for example.

　（Ｂ）駆動装置は、モータを有する駆動装置だけではなく、乗員の手動による装置でもよい。
　（Ｃ）ウィンドウガラスの破損検出装置は、乗用車の右前ドアへの適用に限られず、他の側部ドア、側部ドア以外の後部ドアや屋根に設けられた開閉式ガラスルーフに適用されてもよいことは云うまでもない。 (B) The drive device may be not only a drive device having a motor but also a device manually operated by an occupant.
(C) The window glass breakage detection device is not limited to the application to the right front door of a passenger car, but may be applied to other side doors, rear doors other than side doors, and openable glass roofs provided on the roof. Needless to say, it is good.
　（Ｄ）センサユニット６０は一対の磁気センサ６１，６２を備える代わりに、１つの磁気センサを具備するものであってもよい。
　（Ｅ）センサユニット６０のセンサは、磁気センサ以外に、赤外線センサであってもよい。クリップ４０の第２部材４２に赤外線センサと対向するように赤外線反射膜を設けてもよい。即ち、図７Ａ，Ｂでの磁石５０に代わり赤外線反射膜を設けるとともに、磁気式のセンサユニット６０の代わりに赤外線センサを設け、赤外線センサから赤外線を発し、反射膜からの反射光を入射し、反射光の有無によりクリップ４０の落下を検出するようにしてもよい。 (D) The sensor unit 60 may include one magnetic sensor instead of the pair of magnetic sensors 61 and 62.
(E) The sensor of the sensor unit 60 may be an infrared sensor other than the magnetic sensor. An infrared reflecting film may be provided on the second member 42 of the clip 40 so as to face the infrared sensor. 7A and 7B, an infrared reflection film is provided instead of the magnet 50, an infrared sensor is provided instead of the magnetic sensor unit 60, infrared rays are emitted from the infrared sensor, and reflected light from the reflection film is incident. You may make it detect fall of the clip 40 by the presence or absence of reflected light.
　（Ｆ）クリップ４０は、ウィンドウガラスの端部のうちの車両ドア１の内部の目立たない所に設置すればよく、ウィンドウガラス５の下端部に設置する以外に、クリップ４０は例えばウィンドウガラス５の側面での下部に設置してもよい。 (F) The clip 40 should just be installed in the inconspicuous place inside the vehicle door 1 among the edge parts of a window glass, and besides installing in the lower end part of the window glass 5, the clip 40 is the window glass 5, for example. You may install in the lower part in the side.
　（Ｇ）クリップ４０の第２部材４２はウィンドウガラス５に接着したが、弾性シートを介在させ、第２部材４２がウィンドウガラス５に対して滑らないようにしてもよい。
　（Ｈ）クリップ４０の第１部材４１にウィンドウガラス５と接触する突起４５を設ける以外に、第１部材４１に突起を設けずに第２部材４２に突起を設けてよく、あるいは、第１部材４１および第２部材４２に突起をそれぞれ設けてもよい。要は、第１部材４１および第２部材４２の少なくとも一方においてウィンドウガラス５と突起にて接触する構成とすればよい。さらに、第１部材４１、第２部材４２共に突起を設けない構成としてもよく、ガラス強度が低下した際にクリップ４０がウィンドウガラス５の端部を粉砕するような挟持力を有していればよい。 (G) Although the second member 42 of the clip 40 is bonded to the window glass 5, an elastic sheet may be interposed so that the second member 42 does not slide with respect to the window glass 5.
(H) In addition to providing the first member 41 of the clip 40 with the protrusion 45 in contact with the window glass 5, the first member 41 may be provided with a protrusion on the second member 42 without providing the protrusion, or the first member 41 and the second member 42 may be provided with protrusions, respectively. In short, at least one of the first member 41 and the second member 42 may be configured to come into contact with the window glass 5 by a protrusion. Furthermore, it is good also as a structure which does not provide a protrusion in both the 1st member 41 and the 2nd member 42, and if the clip 40 has the clamping force which grind | pulverizes the edge part of the window glass 5 when glass strength falls. Good.
　（Ｉ）開閉式ウィンドウガラスではなく固定式のウィンドウガラスに取り付けるようにしてもよい。
　次に、第２の実施の形態を、第１の実施の形態との相違点を中心に説明する。 (I) You may make it attach to fixed type window glass instead of opening-and-closing type window glass.
Next, the second embodiment will be described focusing on the differences from the first embodiment.
　図１３は、第２実施形態における検出具８０とセンサユニット６０の斜視図を示す。図１３はウィンドウガラス５が割られる前であり、図１４はウィンドウガラス５が割られたときを示している。 FIG. 13 shows a perspective view of the detector 80 and the sensor unit 60 in the second embodiment. FIG. 13 shows a state before the window glass 5 is broken, and FIG. 14 shows a state when the window glass 5 is broken.
　図１５Ａ－Ｃは検出具８０を示し、図１５Ａは検出具８０をウィンドウガラス５に取り付ける前を示し、図１５Ｂは検出具８０をウィンドウガラス５に取り付けた状態を示し、図１５Ｃはウィンドウガラス５が割られたときを示している。第２実施形態の検出具８０は、第１の実施形態におけるクリップ４０とは異なり、ウィンドウガラス５を挟持せず、かつ、ウィンドウガラス５の片面のみに貼着され、ウィンドウガラス５の端部でなくとも取り付け可能である。 15A to 15C show the detection tool 80, FIG. 15A shows the detection tool 80 before being attached to the window glass 5, FIG. 15B shows the state where the detection tool 80 is attached to the window glass 5, and FIG. Is shown when is broken. Unlike the clip 40 in the first embodiment, the detection tool 80 of the second embodiment does not sandwich the window glass 5 and is attached to only one side of the window glass 5, and at the end of the window glass 5. It can be installed at least.
　図１３において、ウィンドウガラス５の破損に伴う検出具８０の少なくとも一部の変位が検出装置としてのセンサユニット６０により検出される。
　検出具８０は、帯板の板ばね用鋼板を折り曲げて構成され、第１接触部８１、第２接触部８２、第３接触部８３、第１付勢用アーム部８４、および第２付勢用アーム部８５を有している。第１接触部８１は平板状をなし、その左側面から円弧状をなすアーム部８４が延び、アーム部８４の先端には平板状の第２接触部８２が連結されている。同様に、第１接触部８１の右側面から円弧状をなすアーム部８５が延び、アーム部８５の先端には平板状の第３接触部８３が連結されている。第１接触部８１には板状の永久磁石５５が固定されている。 In FIG. 13, the displacement of at least a part of the detection tool 80 due to the breakage of the window glass 5 is detected by a sensor unit 60 as a detection device.
The detector 80 is configured by bending a steel plate for a leaf spring as a band plate, and includes a first contact portion 81, a second contact portion 82, a third contact portion 83, a first biasing arm portion 84, and a second biasing force. Arm portion 85 is provided. The first contact portion 81 has a flat plate shape, and an arm portion 84 having an arc shape extends from the left side surface. A flat plate-like second contact portion 82 is connected to the tip of the arm portion 84. Similarly, an arc-shaped arm portion 85 extends from the right side surface of the first contact portion 81, and a flat plate-like third contact portion 83 is connected to the tip of the arm portion 85. A plate-like permanent magnet 55 is fixed to the first contact portion 81.
　図１５Ａに示すように、検出具８０をウィンドウガラス５に取り付ける前においては第１接触部８１がウィンドウガラス５の片面に当接している状態では第２接触部８２と第３接触部８３がウィンドウガラス５の片面から離間している。 As shown in FIG. 15A, before the detector 80 is attached to the window glass 5, the second contact part 82 and the third contact part 83 are in the window when the first contact part 81 is in contact with one side of the window glass 5. The glass 5 is separated from one side.
　そして、図１５Ｂに示すように、検出具８０の第２接触部８２と第３接触部８３とを検出具８０のばね力に抗してウィンドウガラス５に接着する。すると、検出具８０の第２接触部８２と第３接触部８３は力Ｆ１にてウィンドウガラス５の表面５ａ側へ付勢され、第１接触部８１は力Ｆ２にてウィンドウガラス５の裏面５ｂ側へ付勢される。この状態では、ウィンドウガラス５の片面においてウィンドウガラス５の面５ａ，５ｂでずれた位置で面５ａ，５ｂに対し互いに逆方向にウィンドウガラス５が付勢されている。即ち、ウィンドウガラス５に互い違いに力Ｆ１，Ｆ２が加わっている。 15B, the second contact portion 82 and the third contact portion 83 of the detection tool 80 are bonded to the window glass 5 against the spring force of the detection tool 80. Then, the second contact portion 82 and the third contact portion 83 of the detection tool 80 are urged toward the front surface 5a side of the window glass 5 by the force F1, and the first contact portion 81 is pressed by the force F2 on the back surface 5b of the window glass 5. It is urged to the side. In this state, the window glass 5 is urged in opposite directions with respect to the surfaces 5a and 5b at positions shifted by the surfaces 5a and 5b of the window glass 5 on one surface of the window glass 5. That is, forces F1 and F2 are applied to the window glass 5 alternately.
　この図１５Ｂに示す状態から、ウィンドウガラス５が破損すると、ウィンドウガラス５の強度が低下することによって検出具８０がその付勢力により、図１５Ｃに示すようにウィンドウガラス５の破損に伴いウィンドウガラス５の一部領域が粉砕される。これにより、図１４に示すように、検出具８０が磁石５５と共に矢印の方向に落下し、磁石５５の落下がセンサユニット６０、すなわち磁気センサ６１，６２により検出される。その結果、ウィンドウガラス５の破損を検出することができる。 When the window glass 5 is broken from the state shown in FIG. 15B, the strength of the window glass 5 is reduced and the detector 80 is biased by the urging force. As shown in FIG. Part of the area is crushed. As a result, as shown in FIG. 14, the detector 80 falls together with the magnet 55 in the direction of the arrow, and the fall of the magnet 55 is detected by the sensor unit 60, that is, the magnetic sensors 61 and 62. As a result, breakage of the window glass 5 can be detected.
　また、ウィンドウガラス５の破損に伴いウィンドウガラス５が完全に粉砕せずに残るような場合でもウィンドウガラス５の破損を確実に検出することができる。さらに、ウィンドウガラス５が全閉位置にないときも、ウィンドウガラス５の破損を検出することができる。また、ウィンドウガラス５の片面において付勢用アーム部８４，８５により連結された一対の接触部、すなわち接触部８１と接触部８２の対および接触部８１と接触部８３の対が、ウィンドウガラス５の面でずれた位置で接触する状態でガラス面に対し互いに逆方向に付勢しているので、ウィンドウガラス５の破損に伴ってウィンドウガラス５の一部領域を確実に粉砕してウィンドウガラス５の破損を確実に検出することができる。 Further, even when the window glass 5 remains without being completely pulverized due to the breakage of the window glass 5, the breakage of the window glass 5 can be reliably detected. Furthermore, the breakage of the window glass 5 can be detected even when the window glass 5 is not in the fully closed position. In addition, a pair of contact portions connected by the urging arm portions 84 and 85 on one side of the window glass 5, that is, a pair of the contact portion 81 and the contact portion 82 and a pair of the contact portion 81 and the contact portion 83 are arranged in the window glass 5. Since the glass surfaces are biased in directions opposite to each other while being in contact with each other at a position shifted with respect to the surface of the window glass 5, a part of the window glass 5 is reliably crushed as the window glass 5 is broken. Can be reliably detected.
　なお、検出具８０は、第１接触部８１の左右からアーム部８４，８５を介して接触部８２，８３が連結されているが、第１接触部８１から１つのアーム部を介して１つの接触部が連結されていてもよい。この場合には、両方の接触部を共にウィンドウガラス５の片面に接着する。あるいは、第１接触部８１から３つ以上のアーム部を介して３つ以上の接触部が連結されていてもよい。また、検出具８０は、板ばね用鋼板に代わる材料として、他の弾性のある材料、例えば、カーボン製であってもよい。 The detection tool 80 is connected to the contact portions 82 and 83 from the left and right sides of the first contact portion 81 via the arm portions 84 and 85, but from the first contact portion 81 to the single contact portion via one arm portion. The contact part may be connected. In this case, both contact portions are bonded to one side of the window glass 5. Alternatively, three or more contact portions may be connected from the first contact portion 81 via three or more arm portions. Further, the detector 80 may be made of another elastic material, for example, carbon, as a material to replace the plate spring steel plate.
　上記第２実施形態によれば、以下の効果を奏する。
　（１）ウィンドウガラス破損検出具８０は、ウィンドウガラス５の片面において付勢用アーム部８４（８５）により連結された少なくとも一対の接触部（接触部８１と接触部８２の対および接触部８１と接触部８３の対のうちの少なくとも一方）がウィンドウガラス５の面でずれた位置で接触する状態で、ガラス面に対し互いに逆方向に付勢されている。これにより、ウィンドウガラス５の面でずれた位置で接触する状態で、自身の弾性にてガラス面５ａ，５ｂに対し互いに逆方向に付勢している。この場合には、挟持しなくてもウィンドウガラス５の片面のみに取り付けられ、ウィンドウガラス５の端部でなくとも取り付け可能である。 According to the said 2nd Embodiment, there exist the following effects.
(1) The window glass breakage detector 80 includes at least a pair of contact portions (a pair of the contact portion 81 and the contact portion 82 and a contact portion 81) connected to each other by the urging arm portion 84 (85) on one side of the window glass 5. In a state where at least one of the pair of contact portions 83 is in contact with a position shifted on the surface of the window glass 5, the glass surfaces are biased in directions opposite to each other. Accordingly, the glass surfaces 5a and 5b are urged in opposite directions to each other by their own elasticity while being in contact with each other at a position shifted on the surface of the window glass 5. In this case, even if it is not clamped, it is attached only to one side of the window glass 5 and can be attached even if it is not the end of the window glass 5.

FIGS. 20A to 20D, 21A, and B show a state where the window glass 5 is broken and a part of the region is crushed.
　図１６，図１７Ａに示すように、ウィンドウガラス５には貫通孔５ｃが形成されている。貫通孔５ｃは上下方向に延びる長穴である。検出具９０は貫通孔５ｃを貫通する状態で固定され、プレート部９２，９３が、ウィンドウガラス５の表面５ａに当接し、また、ウィンドウガラス５の表面５ａにおいて被検出部材としての永久磁石５６を把持している。 As shown in FIGS. 16 and 17A, the window glass 5 has a through hole 5c. The through hole 5c is a long hole extending in the vertical direction. The detector 90 is fixed in a state of penetrating the through hole 5c, the plate portions 92 and 93 abut against the surface 5a of the window glass 5, and the permanent magnet 56 as a member to be detected is placed on the surface 5a of the window glass 5. Holding.
　検出具９０について、図１６に示すように、検出具９０は正面側において磁石５６を開閉式ウィンドウガラスの非破損時において把持し、破損時には把持を解除することができる。磁石５６は四角板状をなし、かつ、左右両側面にチャネル状の切り欠き（凹部）５６ａが形成されている（図２０Ａ参照）。 As shown in FIG. 16, the detection tool 90 can grip the magnet 56 on the front side when the openable window glass is not broken, and can release the grip when the breakage occurs. The magnet 56 has a square plate shape, and channel-shaped notches (concave portions) 56a are formed on both left and right side surfaces (see FIG. 20A).
　図１６に示すように、検出具９０は、一枚の帯板状の板ばね用鋼板を折り曲げて構成されている。検出具９０は固定部９１とプレート部９２，９３を有している。固定部９１はチャネル状に形成され、ウィンドウガラス５の貫通孔５ｃに変形して挿入される。プレート部９２，９３は左右に延びる長方形をなし、固定部９１から左右に延びている。図１８Ｂに示すように、ウィンドウガラス５の裏面５ｂ側において固定部９１の係合部９１ａ間の幅がウィンドウガラス５の貫通孔５ｃの幅より広くなっており、係合部９１ａはウィンドウガラス５の貫通孔５ｃの縁部で接触している。また、ウィンドウガラス５の表面５ａ側においてプレート部９２，９３が、図１７Ｂ、図１８Ａ，Ｂにおいて二点鎖線で示す位置から実線で示す位置に自身のばね力に抗して変形しており、ウィンドウガラス５の表面５ａを付勢している。つまり、固定部９１の係合部９１ａとプレート部９２，９３とが、ウィンドウガラス５の貫通孔５ｃを通してウィンドウガラス５を両面から挟持し、かつ、図１８Ｂにおいて力Ｆ３，Ｆ４で表したようにウィンドウガラス５の表面５ａと裏面５ｂで貫通孔５ｃからの距離が異なる位置で互いに逆方向にウィンドウガラス５を付勢している。即ち、ウィンドウガラス５に検出具９０が取り付けられる前ではプレート部９２，９３が図１８Ｂに二点鎖線で示す場所に位置し、ウィンドウガラス５に検出具９０が取り付けられると、プレート部９２，９３が図１８Ｂに実線で示すようにウィンドウガラス５の表面５ａ側に変形してウィンドウガラス５の表面５ａを付勢する。 As shown in FIG. 16, the detection tool 90 is configured by bending a single plate steel plate for a leaf spring. The detector 90 has a fixed portion 91 and plate portions 92 and 93. The fixing portion 91 is formed in a channel shape and is inserted into the through hole 5c of the window glass 5 while being deformed. The plate portions 92 and 93 have a rectangular shape extending left and right, and extend from the fixed portion 91 to the left and right. As shown in FIG. 18B, the width between the engaging portions 91 a of the fixing portion 91 is wider than the width of the through hole 5 c of the window glass 5 on the back surface 5 b side of the window glass 5, and the engaging portion 91 a Of the through hole 5c. Further, the plate portions 92 and 93 on the surface 5a side of the window glass 5 are deformed against the spring force from the position shown by the two-dot chain line in FIGS. 17B and 18A and B to the position shown by the solid line, The surface 5a of the window glass 5 is urged. That is, as shown by forces F3 and F4 in FIG. 18B, the engaging portion 91a of the fixing portion 91 and the plate portions 92 and 93 sandwich the window glass 5 from both sides through the through holes 5c of the window glass 5. The window glass 5 is urged in opposite directions at positions where the distance from the through hole 5c is different between the front surface 5a and the back surface 5b of the window glass 5. That is, before the detector 90 is attached to the window glass 5, the plate portions 92 and 93 are located at a position indicated by a two-dot chain line in FIG. 18B, and when the detector 90 is attached to the window glass 5, the plate portions 92 and 93 are attached. However, as shown by a solid line in FIG. 18B, the surface 5a of the window glass 5 is deformed to urge the surface 5a of the window glass 5.
　図１７Ａ，Ｂに示すように、検出具９０において永久磁石５６を保持するための把持部としての一対のアーム９５，９６が設けられている。一対のアーム９５，９６は、プレート部９２，９３と協働して磁石５６をウィンドウガラスの非破損時において把持し、破損時には把持を解除する。 As shown in FIGS. 17A and 17B, a pair of arms 95 and 96 are provided as gripping portions for holding the permanent magnet 56 in the detection tool 90. The pair of arms 95 and 96 cooperate with the plate portions 92 and 93 to grip the magnet 56 when the window glass is not broken, and release the grip when the window glass is broken.
　詳しくは、検出具９０において左右方向の中央部には透孔９４が形成されている。検出具９０において透孔９４を画成する左右の側壁からアーム９５，９６が中央部に向けて突出している。アーム９５，９６は直線的に延びる帯板状をなし、図１８Ａに示すように、先端部において２回折り曲げられている。検出具９０をウィンドウガラス５に取り付けた状態で永久磁石５６の切り欠き５６ａにおける角部がアーム９５，９６の先端の磁石係止部９５ａ，９６ａに係合して永久磁石５６が左右方向および上下方向に移動できないようになっている。即ち、図１８Ａにおいて二点鎖線にてウィンドウガラス５に検出具９０が取り付けられる前のアーム９５，９６の位置を表し、アーム９５，９６は取り付けられる前では磁石５６から離れた場所に位置する。そして、ウィンドウガラス５に検出具９０が取り付けられると、アーム９５，９６が図１８Ａに実線で示すように変形して磁石係止部９５ａ，９６ａにて磁石５５の両側を正面側から固定する。 More specifically, a through hole 94 is formed in the center of the detection tool 90 in the left-right direction. In the detection tool 90, arms 95 and 96 project from the left and right side walls defining the through hole 94 toward the center. The arms 95 and 96 have a strip shape extending linearly, and are bent twice at the tip as shown in FIG. 18A. With the detector 90 attached to the window glass 5, the corners of the notch 56a of the permanent magnet 56 engage with the magnet locking portions 95a and 96a at the tips of the arms 95 and 96 so that the permanent magnet 56 moves in the horizontal direction and the vertical direction. It cannot move in the direction. That is, the position of the arms 95 and 96 before the detector 90 is attached to the window glass 5 is indicated by a two-dot chain line in FIG. 18A, and the arms 95 and 96 are located away from the magnet 56 before being attached. When the detector 90 is attached to the window glass 5, the arms 95 and 96 are deformed as indicated by solid lines in FIG. 18A, and both sides of the magnet 55 are fixed from the front side by the magnet locking portions 95a and 96a.
　そして、図１９Ａ－Ｄに示すように、ウィンドウガラス５が破損すると、ウィンドウガラス５の強度が低下する。これにより、検出具９０がその付勢力により図２０Ａ－Ｄ，２１Ａ，Ｂに示すようにウィンドウガラス５の貫通孔５ｃの周辺部を粉砕する。これによりウィンドウガラス５の破損が検出できる。 Then, as shown in FIGS. 19A to 19D, when the window glass 5 is broken, the strength of the window glass 5 is lowered. As a result, the detection tool 90 crushes the peripheral portion of the through hole 5c of the window glass 5 as shown in FIGS. Thereby, breakage of the window glass 5 can be detected.
　よって、ウィンドウガラス５の破損に伴いウィンドウガラス５が完全に粉砕せずに残るような場合でもウィンドウガラス５の破損を確実に検出することができる。また、ウィンドウガラス５が全閉位置にないときも、ウィンドウガラス５の破損を検出することができる。 Therefore, even when the window glass 5 remains without being crushed due to the breakage of the window glass 5, the breakage of the window glass 5 can be reliably detected. Moreover, even when the window glass 5 is not in the fully closed position, the breakage of the window glass 5 can be detected.
　検出具９０における係合部９１ａとプレート部９２，９３とは、ウィンドウガラス５の両面を挟持し、ウィンドウガラス５の一方の面と他方の面で貫通孔５ｃからの距離が異なる位置で互いに接近する方向に付勢しているので、ウィンドウガラス５の破損に伴ってウィンドウガラス５の一部領域を確実に粉砕し、ウィンドウガラス５の破損を確実に検出することができる。 The engaging portion 91a and the plate portions 92 and 93 in the detection tool 90 sandwich both surfaces of the window glass 5, and approach each other at a position where the distance from the through hole 5c is different between one surface and the other surface of the window glass 5. Since the window glass 5 is broken, a part of the window glass 5 is reliably pulverized as the window glass 5 is broken, and the breakage of the window glass 5 can be reliably detected.
　また、ウィンドウガラスが割れると磁石５６の把持を解除して磁石５６の落下を検出できる。これにより、例えば、検出具９０がどこかに引っかかったり検出具９０を車体（例えばウィンドウガラス５）に固定して検出具９０の落下が妨げられたりしても、ウィンドウガラスの破損を検出することができる。 Also, when the window glass is broken, the gripping of the magnet 56 is released and the fall of the magnet 56 can be detected. Thereby, for example, even if the detection tool 90 is caught somewhere or the detection tool 90 is fixed to the vehicle body (for example, the window glass 5) and the fall of the detection tool 90 is prevented, the breakage of the window glass is detected. Can do.
