Description
本発明は、ワゴン車やワンボックスカーなどのように車体の前後に移動するスライドドアやバックドア等のドアやサンルーフなどのように、車体の開口部を開閉する開閉物と、開口部との間に指等の異物が挟み込まれると対応する信号を出力して異物の存在を検知するセンサーが組込まれたセンサー付きプロテクターに関する。 The present invention relates to an opening and closing object that opens and closes an opening of a vehicle body, such as a sliding door that moves back and forth of a vehicle body such as a wagon car and a one-box car, a sunroof, and the like. The present invention relates to a protector with a sensor in which a sensor for detecting the presence of a foreign object is output by outputting a corresponding signal when a foreign object such as a finger is sandwiched therebetween.
図６に示すように、ワゴン車などのようにスライドドア１（あるいはバックドア）によって車体の開口部を開閉する自動車や、図７に示すように、サンルーフ２によって車体の開口部を開閉する自動車においては、センサー付きプロテクター１０，２０が取付けられている。 As shown in FIG. 6, an automobile that opens and closes the opening of the vehicle body by a sliding door 1 (or back door) such as a wagon car, or an automobile that opens and closes the opening of a vehicle body by a sunroof 2 as shown in FIG. 7. The sensor-equipped protectors 10 and 20 are attached.
例えば、スライドドア１の前端面には、車体前側に向けて突設され、図８に示すような、車両上下に延びるセンサー付きプロテクター１０が取付けられている。
センサー付きプロテクター１０は、図９及び図１０に示すように、スライドドア１の前端面に取付けられる、車内側壁１１ａ，車外側壁１１ｂ及び連結壁１１ｃからなる断面略Ｕ字形状の取付基部１１とそれに一体成形された中空部１２を備え、中空部１２には、スライドドア１とボディ側開口部（フロントドア（サイドドア）の場合もある）との間に人体の一部（指や手足）などの異物が挟まった場合にその挟み込みを検知して対応する電気信号を出力するセンサー（感圧センサー）Ｓが取付けられている（例えば、特許文献１，２参照）。
なお、センサー付きプロテクター１０の下部では、取付基部１１の車内側壁１１ａ側に断面Ｃ字形状のチャンネル部１３が一体成形されていて、感圧センサーＳに接続されるワイヤーハーネスＷを保持している。また、取付基部１１の内側には複数の保持リップ１４，１４が設けられ、また取付基部１１には剛性をアップさせるために断面略Ｕ字形状の芯材１５が埋設されている。さらに取付基部１１の車外側壁１１ｂには装飾用リップ１６が設けられている。
For example, a protector 10 with a sensor that protrudes toward the front side of the vehicle body and extends up and down as shown in FIG. 8 is attached to the front end surface of the slide door 1.
As shown in FIGS. 9 and 10, the sensor-equipped protector 10 is attached to the front end surface of the slide door 1, and includes a mounting base portion 11 having a substantially U-shaped cross section including a vehicle inner side wall 11 a, a vehicle outer side wall 11 b and a connecting wall 11 c. A hollow portion 12 formed integrally therewith is provided. In the hollow portion 12, a part of a human body (finger or limb) is provided between the slide door 1 and a body side opening (in some cases, a front door (side door)). A sensor (pressure-sensitive sensor) S that detects the pinching and outputs a corresponding electric signal when a foreign object such as a pinch is pinched is attached (for example, see Patent Documents 1 and 2).
In addition, in the lower part of the protector 10 with the sensor, a channel portion 13 having a C-shaped cross section is integrally formed on the side of the vehicle interior side wall 11a of the mounting base 11, and the wire harness W connected to the pressure sensor S is held. . A plurality of holding lips 14, 14 are provided inside the mounting base 11, and a core 15 having a substantially U-shaped cross section is embedded in the mounting base 11 in order to increase rigidity. Further, a decorative lip 16 is provided on the vehicle outer side wall 11 b of the mounting base 11.
センサー（感圧センサー）Ｓは、車両上下方向（長手方向）に延びる２本の芯線（電極線）３１，３２が、空間部３３を介して設けられた導電性のゴム様弾性体（導電部）３４，３５に埋設されるようにして中空部１２内に固定されてなるもので、スライドドア１の閉時にスライドドア１とボディ側開口部との間に異物が挟み込まれると中空部１２が部分的に押圧されて潰れ、ゴム様弾性体３４，３５が接触して２本の芯線３１，３２が短絡するようになっている。そして、この電気信号の変化が、センサー付きプロテクター１０の下側端末部分で２本の芯線３１，３２に結線されたリード線３６，３６に接続された制御装置４０に伝えられることによって異物の存在が検知される。なおリード線３６，３６は絶縁体で被覆された状態でワイヤーハーネスＷによって束ねられているが、先端は被覆部３７，３７からむき出した裸線となっている。 The sensor (pressure sensor) S is a conductive rubber-like elastic body (conductive portion) in which two core wires (electrode wires) 31 and 32 extending in the vehicle vertical direction (longitudinal direction) are provided via a space 33. ) It is fixed in the hollow portion 12 so as to be embedded in 34 and 35. When a foreign object is sandwiched between the slide door 1 and the body side opening when the slide door 1 is closed, the hollow portion 12 is The two core wires 31 and 32 are short-circuited by being partially pressed and crushed, and the rubber-like elastic bodies 34 and 35 are in contact with each other. Then, the change of the electric signal is transmitted to the control device 40 connected to the lead wires 36 and 36 connected to the two core wires 31 and 32 at the lower end portion of the protector 10 with the sensor, thereby the presence of foreign matter. Is detected. The lead wires 36 and 36 are bundled by the wire harness W in a state of being covered with an insulator, but the leading ends are bare wires that are exposed from the covering portions 37 and 37.
しかしながら、中空部１２の内周面において、２つの導電性のゴム様弾性体（導電部）３４，３５が埋設された部分はその分、肉厚が厚くなるので強度的に強いが、導電部３４，３５のない部分、すなわち中空部１２の断面形状において空間部３３の両端３３ａ，３３ｂが中空部１２の外殻内周面に連設する部分では肉厚が薄く強度的に弱いため、図１１に示すように、人の乗降車時にカギ等の突起物Ｚが強く当接することによって強度的に弱い部分が破損したり破れたりする恐れがあった。 However, on the inner peripheral surface of the hollow portion 12, the portion in which the two conductive rubber-like elastic bodies (conductive portions) 34 and 35 are embedded is thicker, and thus the strength is strong. In the portion where 34 and 35 are not provided, that is, in the cross-sectional shape of the hollow portion 12, the portion where both ends 33 a and 33 b of the space portion 33 are connected to the inner peripheral surface of the outer shell of the hollow portion 12 is thin and weak in strength. As shown in FIG. 11, when a person gets on and off the vehicle, there is a risk that a weakly strong portion may be broken or torn due to the protrusion Z such as a key coming into strong contact.
また、図１１に示したものは、空間部３３の断面形状が略長方形状（略矩形状）であるが、ゴム様弾性体３４，３５の形状及び配置によっては空間部の両端３３ａ，３３ｂが中空部１２の外殻内周面に連設する部分が、中空部１２の断面形状において取付基部１１側に位置する場合がある。このような場合、空間部３３の両端３３ａ，３３ｂが中空部１２の外殻内周面に連設する部分の位置は、カギ等の突起物Ｚが特に引っかかりやすい位置となるので破損や破れの危険性は大きい。 11 shows that the cross-sectional shape of the space portion 33 is substantially rectangular (substantially rectangular), but depending on the shape and arrangement of the rubber-like elastic bodies 34 and 35, both ends 33a and 33b of the space portion may be A portion connected to the inner peripheral surface of the outer shell of the hollow portion 12 may be located on the mounting base 11 side in the cross-sectional shape of the hollow portion 12. In such a case, the position of the portion where both ends 33a, 33b of the space portion 33 are connected to the inner peripheral surface of the outer shell of the hollow portion 12 is a position where the projection Z such as a key is particularly easily caught, so that it is not damaged or torn. The danger is great.
このように中空部１２が破れてしまうと雨水や洗車水などが浸入してセンサー機能が失われ、その結果、スライドドア１やサンルーフ２の開閉が誤動作するといった不具体が懸念される。 If the hollow portion 12 is broken in this way, rain water, car wash water, etc. enter and the sensor function is lost, and as a result, there is a concern that the sliding door 1 and the sunroof 2 may be erroneously opened and closed.
なお、特許文献１及び特許文献２に記載された発明は、中空部にスライドドアに弾接する大きさのリップ部を設けて見栄えをよくしたり、センサーの取付精度を向上させるものであるが、中空部の薄肉部にカギ等の突起物Ｚが当接して中空部が破損したり破れたりすることを防止するものではなく、これに関連した発想は一切記載されていない。 In addition, the invention described in Patent Document 1 and Patent Document 2 is to improve the appearance by providing a lip portion of a size that elastically contacts the slide door in the hollow portion, or to improve the mounting accuracy of the sensor, It does not prevent the protrusion Z such as a key from coming into contact with the thin portion of the hollow portion, and the hollow portion is prevented from being damaged or torn, and no idea related to this is described.
そこで、本発明の目的とするところは、異物の当接によって破損等が生じることを防止しうるセンサー付きプロテクターを提供することにある。 Accordingly, an object of the present invention is to provide a protector with a sensor that can prevent damage or the like due to contact of foreign matter.

前記２つの導電部（３４，３５，５４，５５）は、前記取付基部（１１）側に設けられた中空下部導電部（３５，５５）と、先端側に設けられた中空上部導電部（３４，５４）からなり、前記空間部（３３，５３）の車外側端部（３３ｂ，５３ｂ）が前記中空部（１２）の外殻内周面に直接連設されるような形状でかつ配置されてなるとともに、その空間部（３３，５３）の車外側端部（３３ｂ，５３ｂ）が前記中空部（１２）の外殻内周面に直接連設された部位を、前記中空部（１２）の外側から覆って保護するリップ状の第一ガード部（６１）を形成したことを特徴とする。
なお、ここで、「電気信号の変化」には、２本の芯線が短絡することによる変化や、静電容量の変化が含まれる。

Here, the “change in electrical signal” includes a change due to a short circuit between two core wires and a change in capacitance.

A lip-shaped second guard part (62) that covers and protects the connected parts from the outside of the hollow part (12) is further formed.

The "V" -shaped opening with substantially the same width is directed to the mounting base (11) side, and the vehicle inner end (53a) is directly connected to the mounting base (11). Being

また本発明は、前記取付基部（１１）と前記中空部（１２）と前記導電部（３４，３５，５４，５５）及び前記芯線（３１，３２）は一体成形されていることを特徴とする。 In the present invention, the mounting base (11), the hollow portion (12), the conductive portions (34, 35, 54, 55) and the core wires (31, 32) are integrally formed. .
なお、括弧内の記号は、図面および後述する発明を実施するための形態に記載された対応要素または対応事項を示す。 Note that symbols in parentheses indicate corresponding elements or corresponding matters described in the drawings and modes for carrying out the invention described later.
本発明によれば、２つの導電部の形状及び配置によってその間の空間部の車外側端部が中空部の外殻内周面に直接連設されるようにされた部位、すなわち、異物の存在を検知するときに中空部の撓み可動部となる肉厚の薄い部位を、リップ状の第一ガード部で中空部の外側から覆って保護するようにしたので、二重構造によって人の乗降車時にカギ等の突起物が車外側から強く当接することがあったとしても中空部の強度的に弱い部分が破損したり破れたりすることが防止される。
したがって、中空部から水が浸入することでセンサー機能が失われ、スライドドアやサンルーフの開閉が誤動作するといった不具体が回避される。
According to the present invention, the portion where the outer end of the space between the two conductive portions is directly connected to the inner peripheral surface of the outer shell of the hollow portion by the shape and arrangement of the two conductive portions, that is, the presence of foreign matter. Since the thin-walled part that becomes the movable part of the hollow part when it is detected is covered with the lip-shaped first guard part from the outside of the hollow part, it is protected by a double structure. Even when protrusions such as keys sometimes come into strong contact with the outside of the vehicle, it is possible to prevent the weakly strong portion of the hollow portion from being damaged or torn.
Therefore, the sensor function is lost due to water intrusion from the hollow portion, and unspecificity such as malfunction of opening / closing of the sliding door and the sunroof is avoided.
また本発明によれば、中空部の車外側に加えて車内側にもリップ状の第二ガード部が形成され、空間部の車内側端部が中空部の外殻内周面に直接連設されるようにされた部位を、外側から覆って保護するようにしたので、車外側に加えて車内側でも二重構造によって人の乗降車時にカギ等の突起物が車内側から強く当接することがあったとしても中空部の強度的に弱い部分が破損したり破れたりすることが防止される。 Further, according to the present invention, the lip-shaped second guard portion is formed on the vehicle inner side in addition to the vehicle outer side of the hollow portion, and the vehicle inner end portion of the space portion is directly connected to the inner peripheral surface of the outer shell of the hollow portion. Because the parts that are made to be covered are protected from the outside, the protrusions such as keys are strongly abutted from the inside of the vehicle by the double structure on the inside of the vehicle in addition to the outside of the vehicle due to the double structure. Even if there is, it is prevented that the weak part of the hollow part is damaged or torn.
また本発明によれば、第一ガード部及び第二ガード部は、それぞれ中空部の先端側から取付基部側でかつ外側に向けて延びる断面略ハ字形状であるので、カギ等の突起物の進入方向に対して第一ガード部及び第二ガード部は垂直に形成されているのではなく角度がついた状態で形成されている。
よって、空間部の車外側端部が連設された中空部の外殻外周面に垂直な方向から進入したカギ等の突起物は、第一ガード部に当接するとその荷重は第一ガード部の傾きによって中空部の先端側に逃がされるので、中空部に加わる衝撃を軽減することで破損や破れの発生が効率的に防止される。同様に、空間部の車内側端部が連設された中空部の外殻外周面に垂直な方向から進入したカギ等の突起物は、第二ガード部に当接するとその荷重は第二ガード部の傾きによって中空部の先端側に逃がされるので、中空部に加わる衝撃を軽減することで破損や破れの発生が効率的に防止される。
Further, according to the present invention, each of the first guard portion and the second guard portion has a substantially C-shaped cross section extending from the distal end side of the hollow portion to the mounting base side and outward, so that projections such as keys are formed. The first guard portion and the second guard portion are not formed perpendicular to the approach direction, but are formed at an angle.
Therefore, when a protrusion such as a key entering from the direction perpendicular to the outer peripheral surface of the outer shell of the hollow portion where the outer end of the space portion is continuously provided contacts the first guard portion, the load is applied to the first guard portion. Because of the inclination, it escapes to the distal end side of the hollow portion, so that the occurrence of breakage and tearing is efficiently prevented by reducing the impact applied to the hollow portion. Similarly, when a protrusion such as a key entering from the direction perpendicular to the outer peripheral surface of the outer shell of the hollow portion where the inner end of the space is continuously provided contacts the second guard portion, the load is applied to the second guard portion. Since the part is released to the tip side of the hollow part due to the inclination of the part, the occurrence of breakage or tearing is efficiently prevented by reducing the impact applied to the hollow part.
また本発明によれば、中空部内に凹形状の中空上部導電部と凸形状の中空下部導電部を設けることで両導電部間の空間部の断面形状を断面略逆「Ｖ」字状で断面略同一幅で「Ｖ」字状の開口部が取付基部側に向くようにしたので、空間部の形状を断面略長方形状（略矩形状）としたものと比較して、中空部が異物の検知の際に撓むことのできる可動範囲を広くとることができ、その結果、車内側と車外側に対してそれぞれ広範囲での検知が可能になる。
このように、空間部の断面形状を断面略逆「Ｖ」字状にすることによって、中空部の外殻内周面に対して連設する空間部の両端部の位置が取付基部側に近づけば近づくほどその薄肉となった部位にカギ等の突起物が引っかかりやすくなるため、薄肉の部位を中空部の外側から覆うように第一ガード部や第二ガード部を形成して保護するものは特に有効である。
Further, according to the present invention, by providing a concave hollow upper conductive part and a convex hollow lower conductive part in the hollow part, the cross-sectional shape of the space part between the two conductive parts is a cross-section with a substantially reverse “V” shape. Since the "V" -shaped opening with substantially the same width is directed to the mounting base side, the hollow portion is made of foreign matter compared to the space having a substantially rectangular cross section (substantially rectangular). The movable range that can be bent at the time of detection can be widened, and as a result, detection in a wide range is possible for each of the inside and outside of the vehicle.
Thus, by making the cross-sectional shape of the space portion into a substantially inverted “V” shape, the positions of both end portions of the space portion connected to the inner peripheral surface of the outer shell of the hollow portion are closer to the mounting base side. As it gets closer, protrusions such as keys are easily caught on the thinned part, so that the first guard part and the second guard part are protected so as to cover the thin part from the outside of the hollow part. It is particularly effective.
また本発明によれば、空間部の形状は、断面略逆「Ｖ」字状で断面略同一幅として前記「Ｖ」字状の開口部が取付基部側に向くものであるが、空間部の車内側端部は中空部の外殻内周面ではなく取付基部に直接連設されるので、中空部の車内側の外殻内周面には中空上部導電部が存在している。よって、中空部の肉厚が車内側では特に薄くなるものではないのでカギ等の突起物の車内側からの当接によって中空部が破損したり破れたりする恐れは少ない。
なお、中空部の車外側には第一ガード部が角度をつけて形成されているので、カギ等の突起物の車外側からの当接による衝撃は軽減され、中空部が破損したり破れたりすることが防止される。
Further, according to the present invention, the shape of the space part is such that the "V" -shaped opening with the substantially reverse "V" shape and the substantially same width of the cross section faces the mounting base side. Since the inner end of the vehicle is directly connected to the mounting base instead of the inner peripheral surface of the outer shell of the hollow portion, the hollow upper conductive portion exists on the inner peripheral surface of the outer shell of the hollow portion. Therefore, since the thickness of the hollow portion is not particularly thin on the inside of the vehicle, there is little possibility that the hollow portion is damaged or torn due to contact of protrusions such as keys from the inside of the vehicle.
In addition, since the first guard part is formed at an angle on the vehicle exterior side of the hollow part, the impact caused by the contact of protrusions such as keys from the vehicle exterior is reduced, and the hollow part may be damaged or torn. Is prevented.
また本発明によれば、取付基部と中空部と導電部及び芯線は一体成形されているので、センサー付きプロテクターを安定した状態でかつ作業時間を短縮化した状態で製造することができる。
このように、センサー付きプロテクターにおいて、取付基部と中空部と導電部及び芯線が一体成形されてなるものは、従来から存在するものではなかった。
Further, according to the present invention, since the mounting base, the hollow portion, the conductive portion, and the core wire are integrally formed, the protector with a sensor can be manufactured in a stable state and with a reduced working time.
Thus, in the protector with a sensor, the attachment base portion, the hollow portion, the conductive portion, and the core wire are not integrally formed.

The vehicle inner end 33a and the vehicle outer end 33b of the space 33 are directly connected to the inner peripheral surface of the hollow portion 12 (the inner peripheral surface of the outer shell of the hollow portion 12).
また、センサー付きプロテクター１０の取付基部１１と中空部１２は、例えば、ＥＰＤＭなどの合成ゴムやＴＰＯ，ＴＰＳといった熱可塑性エラストマーからなる非導電性のゴム様弾性体で押出成形された押出成形部を構成するもので、車両における上下端末部分では型成形され外形が整えられている。なお、センサー付きプロテクター１０の中空部１２は、柔軟性を必要とすることから、発泡したスポンジ材が用いられることもある。また取付基部１１も同様に発泡したスポンジ材が用いられることがある。 The mounting base 11 and the hollow portion 12 of the sensor-equipped protector 10 are formed by extruding a non-conductive rubber-like elastic body made of a synthetic rubber such as EPDM or a thermoplastic elastomer such as TPO or TPS, for example. In the configuration, the upper and lower end portions of the vehicle are molded and trimmed in outer shape. In addition, since the hollow part 12 of the protector 10 with a sensor needs a softness | flexibility, the foamed sponge material may be used. Similarly, the foamed sponge material may be used for the attachment base 11 as well.
そして、中空部１２の車外側には第一ガード部６１が形成されるとともに、中空部１２の車内側には第二ガード部６２が形成されている。
第一ガード部６１は、リップ状で、中空部１２内に形成された空間部３３の車外側端部３３ｂが中空部１２の外殻内周面に直接連設された部位を、中空部１２の外側、すなわち車外側から覆っている。
同様に、第二ガード部６２も、リップ状で、中空部１２内に形成された空間部３３の車内側端部３３ａが中空部１２の外殻内周面に直接連設された部位を、中空部１２の外側、すなわち車内側から覆っている。
A first guard portion 61 is formed on the vehicle outer side of the hollow portion 12, and a second guard portion 62 is formed on the vehicle inner side of the hollow portion 12.
The first guard portion 61 has a lip shape, and a portion in which the vehicle outer side end portion 33 b of the space portion 33 formed in the hollow portion 12 is directly connected to the inner peripheral surface of the outer shell of the hollow portion 12. It covers from the outside of the vehicle, that is, from the outside of the vehicle.
Similarly, the second guard portion 62 is also lip-shaped, and a portion where the vehicle inner side end portion 33a of the space portion 33 formed in the hollow portion 12 is directly connected to the inner peripheral surface of the outer shell of the hollow portion 12, It covers from the outside of the hollow portion 12, that is, from the inside of the vehicle.
第一ガード部６１及び第二ガード部６２は、それぞれ中空部１２の先端側から取付基部１１側でかつ外側に向けて延びる断面略ハ字形状に形成されている。すなわち、第一ガード部６１は、中空部１２の先端側から取付基部１１側でかつ車外側に向けて延び、第二ガード部６２は、中空部１２の先端側から取付基部１１側でかつ車内側に向けて延びるように形成され、第一ガード部６１及び第二ガード部６２のそれぞれの先端は中空部１２の車外側の外殻外周面及び車内側の外殻外周面より外側に突出するように形成されている。
第一ガード部６１と第二ガード部６２の断面形状における長さＬは、空間部３３の車外側端部３３ｂと車内側端部３３ａが中空部１２の外殻内周面に直接連設された部位を、中空部１２の外側から覆うことができる長さで、取付基部１１やボディパネル、あるいはスライドドア１をリヤドアとした場合のフロントドアなどといった他の部位に弾接することができない長さであればよい。本実施形態では、第一ガード部６１と第二ガード部６２の断面形状における長さＬは略同一で中空部１２の断面形状における高さ（先端と取付基部側の後端までの距離）Ｈよりも小さく設定している。
また、第一ガード部６１と第二ガード部６２の断面形状における太さ（幅）は、中空部１２の外郭の太さ（幅）と略同一にしている。
The first guard part 61 and the second guard part 62 are each formed in a substantially C-shaped cross section extending from the distal end side of the hollow part 12 to the attachment base part 11 side and outward. That is, the first guard portion 61 extends from the distal end side of the hollow portion 12 toward the mounting base portion 11 and toward the vehicle outer side, and the second guard portion 62 extends from the distal end side of the hollow portion 12 to the mounting base portion 11 side and the vehicle. The front end of each of the first guard portion 61 and the second guard portion 62 protrudes outward from the outer shell outer peripheral surface of the hollow portion 12 and the outer outer peripheral surface of the inner shell. It is formed as follows.
The length L in the cross-sectional shape of the first guard portion 61 and the second guard portion 62 is such that the vehicle outer end portion 33b and the vehicle inner end portion 33a of the space portion 33 are directly connected to the inner peripheral surface of the outer shell of the hollow portion 12. The length that can cover the outer part from the outside of the hollow part 12, and the length that cannot be elastically contacted with other parts such as the mounting base 11, the body panel, or the front door when the slide door 1 is a rear door. If it is. In this embodiment, the length L in the cross-sectional shape of the first guard portion 61 and the second guard portion 62 is substantially the same, and the height in the cross-sectional shape of the hollow portion 12 (distance from the tip to the rear end on the mounting base side) H. Is set smaller.
In addition, the thickness (width) of the first guard portion 61 and the second guard portion 62 in the cross-sectional shape is substantially the same as the thickness (width) of the outline of the hollow portion 12.
なお、第一ガード部６１と第二ガード部６２は、中空部１２とともに同時押出しによって一体的に成形されているが、別体成形した第一ガード部６１と第二ガード部６２を接着剤などを利用して中空部１２に取付けることも可能である。 In addition, although the 1st guard part 61 and the 2nd guard part 62 are integrally shape | molded by coextrusion with the hollow part 12, the 1st guard part 61 and the 2nd guard part 62 which were molded separately are adhesives etc. It is also possible to attach to the hollow portion 12 using.
このようなセンサー付きプロテクター１０によれば、２つの導電部３４，３５の形状及び配置によってその間の空間部３３の車外側端部３３ｂが中空部１２の外殻内周面に直接連設されるようにされた部位がリップ状の第一ガード部６１によって中空部１２の外側から覆って保護するようにするとともに、空間部３３の車内側端部３３ａが中空部１２の外殻内周面に直接連設されるようにされた部位もリップ状の第二ガード部６２によって中空部１２の外側から覆って保護するようにしたので、二重構造によって人の乗降車時にカギ等の突起物Ｚが車外側及び車内側から強く当接することがあったとしても中空部１２の強度的に弱い部分が破損したり破れたりすることが防止される。 According to such a sensor-equipped protector 10, the outer side end portion 33 b of the space portion 33 therebetween is directly connected to the inner peripheral surface of the outer shell of the hollow portion 12 by the shape and arrangement of the two conductive portions 34 and 35. The portion thus formed is covered and protected from the outside of the hollow portion 12 by the lip-shaped first guard portion 61, and the vehicle inner end portion 33 a of the space portion 33 is formed on the inner peripheral surface of the outer shell of the hollow portion 12. The parts that are directly connected to each other are also covered and protected from the outside of the hollow portion 12 by the lip-shaped second guard portion 62, so that a protrusion Z such as a key is used when a person gets on and off by the double structure. Even if there is a strong contact from the outside and the inside of the vehicle, it is possible to prevent the weak portion of the hollow portion 12 from being damaged or torn.
特に、第一ガード部６１及び第二ガード部６２は、それぞれ中空部１２の先端側から取付基部１１側でかつ外側に向けて延びる断面略ハ字形状に形成されているので、カギ等の突起物Ｚの進入方向に対して第一ガード部６１及び第二ガード部６２は角度がついた状態で形成されている。
よって、図１に示すように、例えば、空間部３３の車外側端部３３ｂが連設された中空部１２の外殻外周面に対して垂直な方向（矢印Ｘ１で示す方向）から進入したカギ等の突起物Ｚは、第一ガード部６１に当接すると矢印Ｘ２で示す方向から第一ガード部６１に沿った方向（矢印Ｘ３で示す方向）に傾き、その結果、カギ等の突起物Ｚの荷重は中空部１２の先端側に逃がされるので、中空部１２に加わる衝撃を軽減することで破損や破れの発生が効率的に防止される。同様に、空間部３３の車内側端部３３ａが連設された中空部１２の外殻外周面に対して垂直な方向から、カギ等の突起物Ｚが進入したとしても第二ガード部６２に当接するとその荷重は第二ガード部６２の傾きによって中空部１２の先端側に逃がされるので、中空部１２に加わる衝撃を軽減することで破損や破れの発生が効率的に防止される。
In particular, since the first guard portion 61 and the second guard portion 62 are each formed in a substantially C-shaped cross section extending from the distal end side of the hollow portion 12 to the mounting base portion 11 side and to the outside, protrusions such as keys are formed. The first guard part 61 and the second guard part 62 are formed with an angle with respect to the entry direction of the object Z.
Therefore, as shown in FIG. 1, for example, the key entered from the direction perpendicular to the outer peripheral surface of the outer shell of the hollow portion 12 where the outer side end portion 33b of the space portion 33 is connected (direction indicated by the arrow X1). When the projection Z such as is tilted against the first guard portion 61, the projection Z tilts from the direction indicated by the arrow X2 to the direction along the first guard portion 61 (direction indicated by the arrow X3). Is released to the distal end side of the hollow portion 12, and the occurrence of breakage and tearing is efficiently prevented by reducing the impact applied to the hollow portion 12. Similarly, even if a projection Z such as a key enters from the direction perpendicular to the outer peripheral surface of the outer shell of the hollow portion 12 where the inner side end portion 33a of the space portion 33 is connected, the second guard portion 62 When abutting, the load is released to the distal end side of the hollow portion 12 due to the inclination of the second guard portion 62. Therefore, the occurrence of breakage or tearing is efficiently prevented by reducing the impact applied to the hollow portion 12.
このように、中空部１２に第一ガード部６１及び第二ガード部６２を形成することによって、中空部１２から水が浸入することでセンサー機能が失われ、スライドドア１やサンルーフ２の開閉が誤動作するといった不具体が回避される。 Thus, by forming the first guard portion 61 and the second guard portion 62 in the hollow portion 12, the sensor function is lost when water enters from the hollow portion 12, and the sliding door 1 and the sunroof 2 can be opened and closed. Unspecificity such as malfunctioning is avoided.
なお本実施形態では、第一ガード部６１及び第二ガード部６２は、それぞれ中空部１２の先端側から取付基部１１側でかつ外側に向けて延びる断面略ハ字形状に形成するようにしたが、図２に示すように、断面略逆ハ字形状に、すなわち第一ガード部６１及び第二ガード部６２は、それぞれ中空部１２の取付基部１１側の後端側から先端側でかつ外側に向けて延びるように形成することもできる。
これによれば、空間部３３の車外側端部３３ｂ及び車内側端部３３ａが連設された中空部１２の外殻部位を外側から覆う第一ガード部６１及び第二ガード部６２は、図１の場合と同様にカギ等の突起物Ｚの進入方向に対して角度がつけられているので、カギ等の突起物Ｚの荷重が逃がされ中空部１２に破損や破れの発生を効率的に防止することはできるが、カギ等の突起物Ｚは当接後には取付基部１１側に当接する方向に傾くため、図１に示したものの方が好ましい。なお、カギ等の突起物Ｚが取付基部１１に当接したとしても取付基部１１は強度的に強いので破損や破れは発生しない。
In the present embodiment, the first guard portion 61 and the second guard portion 62 are each formed in a substantially C-shaped cross section extending from the distal end side of the hollow portion 12 to the attachment base portion 11 side and outward. As shown in FIG. 2, the first guard portion 61 and the second guard portion 62 have a substantially inverted C-shaped cross section, that is, the first guard portion 61 and the second guard portion 62 respectively extend from the rear end side of the hollow base portion 12 to the front end side and to the outer side. It can also be formed to extend toward.
According to this, the 1st guard part 61 and the 2nd guard part 62 which cover the outer shell part of the hollow part 12 with which the vehicle outer side edge part 33b and the vehicle inner side edge part 33a of the space part 33 are continuously provided are shown in FIG. As in the case of 1, the angle is set with respect to the approach direction of the projection Z such as the key, so that the load of the projection Z such as the key is released and the hollow portion 12 is efficiently damaged or broken. However, since the projections Z such as keys are tilted in the direction of contacting the mounting base 11 after contact, the one shown in FIG. 1 is preferable. Even if the projection Z such as a key comes into contact with the mounting base 11, the mounting base 11 is strong and does not break or break.
また本実施形態では、図１に示したように、空間部３３の断面形状を略長方形状（略矩形状）に形成したが、図３及び図４に示すように、中空部１２内に凹形状の中空上部導電部５４と凸形状の中空下部導電部５５を設けることで両導電部５４，５５間の空間部５３の断面形状を断面略逆「Ｖ」字状で断面略同一幅とし、「Ｖ」字状の開口部が取付基部１１側に向くように形成することもできる。
図３に示したものは、空間部５３の車内側端部５３ａ及び車外側端部５３ｂが中空部１２の断面形状における高さの略半分における外殻内周面にそれぞれ連設されるようにしたものである。
また、図４に示したものは、空間部５３の車内側端部５３ａ及び車外側端部５３ｂが中空部１２の車内側端部１２ａ及び車外側端部１２ｂまで達するようにしたものである。すなわち、中空下部導電部５５の断面形状は略山形状で底辺が取付基部１１の連結壁１１ｃに接していて、また中空上部導電部５４の断面形状は略三日月形状で両端部は取付基部１１の連結壁１１ｃ側に近づくように中空部１２の先端から下がっている。
In this embodiment, as shown in FIG. 1, the cross-sectional shape of the space portion 33 is formed in a substantially rectangular shape (substantially rectangular shape). However, as shown in FIGS. 3 and 4, the hollow portion 12 is recessed in the hollow portion 12. By providing the hollow upper conductive portion 54 having a shape and the hollow lower conductive portion 55 having a convex shape, the cross-sectional shape of the space portion 53 between the two conductive portions 54 and 55 is substantially reverse “V” in cross-section and has substantially the same cross-sectional width. It can also be formed such that the “V” -shaped opening is directed to the mounting base 11 side.
3, the vehicle inner end 53a and the vehicle outer end 53b of the space 53 are connected to the inner peripheral surface of the outer shell at approximately half the height in the cross-sectional shape of the hollow portion 12, respectively. It is a thing.
4 shows the vehicle interior end 53a and vehicle exterior end 53b of the space portion 53 reaching the vehicle interior end 12a and vehicle exterior end 12b of the hollow portion 12. That is, the cross-sectional shape of the hollow lower conductive portion 55 is substantially mountain-shaped, and the bottom is in contact with the connecting wall 11c of the mounting base portion 11. The cross-sectional shape of the hollow upper conductive portion 54 is substantially crescent-shaped and both ends are the mounting base portion 11 It is lowered from the tip of the hollow portion 12 so as to approach the connecting wall 11c side.
これらの中空上部導電部５４の中央には芯線３１が埋設され、中空下部導電部５５の中央には芯線３２が埋設されている。また、中空上部導電部５４の下部５４ａ位置を、中空下部導電部５５の頂部５５ａ位置よりも取付基部１１側にして、僅かな撓みであっても両導電部５４，５５が容易に接触するようにして、接点のすれ違いを防止している。
また、中空部１２及び中空部１２に設けられる２つの導電部５４，５５及び空間部５３の断面形状については車内側方向と車外側方向に左右半分に仕切る対称軸に左右略対称で、その対称軸上に芯線３１，３２が位置するようにしている。一般に導電性のゴム様弾性体５４，５５は内部に気泡の無いソリッド材が用いられる。
The core wire 31 is embedded in the center of the hollow upper conductive portion 54, and the core wire 32 is embedded in the center of the hollow lower conductive portion 55. Further, the position of the lower portion 54a of the hollow upper conductive portion 54 is set closer to the mounting base 11 side than the position of the top portion 55a of the hollow lower conductive portion 55 so that both the conductive portions 54 and 55 can easily come into contact with each other even with slight bending. Thus, the passing of the contacts is prevented.
Further, the cross-sectional shapes of the hollow portion 12 and the two conductive portions 54 and 55 and the space portion 53 provided in the hollow portion 12 are substantially symmetrical with respect to the symmetry axis that divides into the left and right halves in the vehicle inner side direction and the vehicle outer side direction. The core wires 31 and 32 are located on the axis. In general, the conductive rubber-like elastic bodies 54 and 55 are made of a solid material without bubbles inside.
このように、空間部５３の断面形状を断面略逆「Ｖ」字状にしたものは、空間部３３の断面形状を略長方形状（略矩形状）に形成したもの（図１）と比較して、中空部１２の外殻が異物の検知の際に撓むことのできる可動範囲を広くとることができ、その結果、車内側と車外側に対して広範囲での検知が可能になる。
しかしながら、空間部５３の断面形状を断面略逆「Ｖ」字状にすることによって、中空部１２の外殻内周面に対して連設する空間部５３の両端部５３ａ，５３ｂの位置が取付基部１１側に近づけば近づくほどその薄肉となった部位にカギ等の突起物Ｚが引っかかりやすくなるため、薄肉の部位を中空部１２の外側から覆うように第一ガード部６１及び第二ガード部６２を形成して保護するものは特に有効である。
Thus, what made the cross-sectional shape of the space part 53 the cross-sectional substantially reverse "V" shape compared with what formed the cross-sectional shape of the space part 33 in the substantially rectangular shape (substantially rectangular shape) (FIG. 1). Thus, it is possible to widen the movable range in which the outer shell of the hollow portion 12 can bend when detecting foreign matter, and as a result, it is possible to detect the vehicle inside and outside the vehicle in a wide range.
However, by making the cross-sectional shape of the space portion 53 into a substantially inverted “V” shape, the positions of both end portions 53 a and 53 b of the space portion 53 that are connected to the inner peripheral surface of the outer shell of the hollow portion 12 are attached. Since the protrusion Z such as a key is likely to be caught in the thinned portion as it gets closer to the base 11 side, the first guard portion 61 and the second guard portion so as to cover the thin portion from the outside of the hollow portion 12. Those that form and protect 62 are particularly effective.
さらに、図５に示すように、中空部１２内に設けられる凹形状の中空上部導電部５４と凸形状の中空下部導電部５５を設けることで両導電部５４，５５間に形成される空間部５３の断面形状を、断面略逆「Ｖ」字状で断面略同一幅として前記「Ｖ」字状の開口部が取付基部側に向くものとするものであるが、空間部５３の車内側端部５３ａは中空部１２の外殻内周面ではなく取付基部１１に直接連設されるようにすることもできる。
これによれば、中空部１２の車内側の外殻内周面にはその全域にわたって中空上部導電部５４が存在するので、中空部１２の肉厚が車内側では特に薄くなるものではない。よって、カギ等の突起物Ｚが車内側から中空部１２に当接したとしても中空部１２が破損したり破れたりする恐れは少ない。
そして、中空部１２の車外側には第一ガード部６１が角度をつけて形成され、中空部１２に対する空間部５３の車外側端部５３ｂの連設外殻部位を外側から覆って保護しているので、カギ等の突起物Ｚが車外側から中空部１２に当接したとしてもその荷重は第一ガード部６１によって中空部１２の先端側に逃がされることで衝撃は軽減され、中空部１２が破損したり破れたりすることが防止される。
Furthermore, as shown in FIG. 5, a space portion formed between the conductive portions 54 and 55 by providing a concave hollow upper conductive portion 54 and a convex hollow lower conductive portion 55 provided in the hollow portion 12. The cross-sectional shape of 53 is a substantially reverse “V” shape with substantially the same width as the cross-section, and the “V” -shaped opening is directed to the mounting base side. The portion 53a may be directly connected to the mounting base 11 instead of the inner peripheral surface of the outer shell of the hollow portion 12.
According to this, since the hollow upper conductive portion 54 exists on the inner peripheral surface of the outer shell on the inner side of the hollow portion 12, the thickness of the hollow portion 12 is not particularly thin on the inner side of the vehicle. Therefore, even if the projection Z such as a key contacts the hollow portion 12 from the inside of the vehicle, there is little possibility that the hollow portion 12 is damaged or torn.
A first guard portion 61 is formed at an angle on the vehicle outer side of the hollow portion 12, and covers and protects the continuous outer shell portion of the vehicle outer side end portion 53 b of the space portion 53 with respect to the hollow portion 12 from the outside. Therefore, even if the projection Z such as a key contacts the hollow portion 12 from the outside of the vehicle, the load is released to the front end side of the hollow portion 12 by the first guard portion 61 so that the impact is reduced. Is prevented from being damaged or torn.
