例えば、人体に自動車のスライドドアが接触した際に、人体に対する衝撃をより和らげるようにするには、特許文献２の技術では、例えば管状部材を覆うゴム製のカバー部材のクッション性を高める必要がある。しかしながら、カバー部材のクッション性を高めると、逆に、管状部材に対する外力が吸収され、挟み込みを適切に検知することが難しくなる。   For example, in order to further reduce the impact on the human body when an automobile slide door comes into contact with the human body, in the technique of Patent Document 2, for example, it is necessary to improve the cushioning property of a rubber cover member that covers the tubular member. is there. However, when the cushioning property of the cover member is increased, on the contrary, the external force on the tubular member is absorbed, and it becomes difficult to detect the pinching appropriately.

また、特許文献１の技術においては、人体にパワーウインドウが接触した際の衝撃を和らげるために、例えば空隙部を大きくすることが考えられる。この場合も、感圧部に対して外力が加わり難くなり、挟み込みを適切に検知することが難しくなる。   Moreover, in the technique of patent document 1, in order to relieve the impact when a power window contacts a human body, it is possible to enlarge a space | gap part, for example. Also in this case, it becomes difficult to apply an external force to the pressure-sensitive portion, and it becomes difficult to detect the pinching appropriately.

本発明は、上記課題に鑑みなされたもので、接触の際のクッション性を高めても、感圧タイプの挟み込み検知スイッチを適切に動作させることができる技術を提供することを目的としている。   The present invention has been made in view of the above problems, and an object of the present invention is to provide a technique capable of appropriately operating a pressure-sensitive type pinching detection switch even when cushioning properties at the time of contact are enhanced.

本願において開示される発明のうち、代表的なものの概要を簡単に説明すれば、次のとおりである。   Of the inventions disclosed in the present application, the outline of typical ones will be briefly described as follows.

すなわち、一実施の形態に係わる挟み込み検知スイッチは、離間された複数の電極線を有する管状の感圧検知部材と、感圧検知部材を覆うカバー部材とを備えている。ここで、カバー部材は、カバー部材を断面視で見たとき、ベース部と、中空部と、中空部を覆うように、ベース部に設けられた変形部とを備えている。変形部には、感圧検知部材として、第１の感圧検知部材と第２の感圧検知部材が配置され、ベース部には、第１の感圧検知部材と第２の感圧検知部材を受ける受け部が配置されている。受け部には、第１の感圧検知部材に対向する位置であって、第１の感圧検知部材を受ける第１の受け面と、第２の感圧検知部材に対向する位置であって、第２の感圧検知部材を受ける第２の受け面とを備えている。   That is, the pinch detection switch according to one embodiment includes a tubular pressure-sensitive detection member having a plurality of spaced apart electrode wires, and a cover member that covers the pressure-sensitive detection member. Here, the cover member includes a base portion, a hollow portion, and a deformation portion provided on the base portion so as to cover the hollow portion when the cover member is viewed in a cross-sectional view. A first pressure-sensitive detection member and a second pressure-sensitive detection member are arranged as pressure-sensitive detection members in the deforming portion, and a first pressure-sensitive detection member and a second pressure-sensitive detection member are arranged in the base portion. The receiving part which receives is arrange | positioned. The receiving portion is a position facing the first pressure-sensitive detection member, a first receiving surface that receives the first pressure-sensitive detection member, and a position facing the second pressure-sensitive detection member. And a second receiving surface for receiving the second pressure-sensitive detection member.

本願において開示される発明のうち、代表的なものによって得られる効果を簡単に説明すれば、以下のとおりである。   Of the inventions disclosed in the present application, effects obtained by typical ones will be briefly described as follows.

すなわち、クッション性を高めながら、挟み込み検知スイッチを適切に動作させることが可能な技術を提供することができる。変形部が、挟み込みまたは引き抜きによって変形したとき、第１の受け面が、第１の感圧検知部材を受け、第２の受け面が、第２の感圧検知部材を受ける。そのため、挟み込みと引き抜きの両方において、挟み込み検知スイッチを適切に動作させることが可能である。また、中空部により、クッション性を高めることが可能である。   That is, it is possible to provide a technique capable of appropriately operating the pinching detection switch while improving cushioning properties. When the deforming portion is deformed by pinching or pulling out, the first receiving surface receives the first pressure-sensitive detection member, and the second receiving surface receives the second pressure-sensitive detection member. Therefore, it is possible to appropriately operate the pinch detection switch in both pinching and pulling out. Moreover, cushioning properties can be enhanced by the hollow portion.

（実施の形態）
図６は、実施の形態に係わる挟み込み検知スイッチを搭載した自動車の構成を示す模式図である。ここでは、挟み込み検知スイッチをパワーウインドウに適用した例を説明する。図６において、２は、自動車２０の窓枠を示している。窓ガラス３が電動アクチュエータにより上下に移動する（上昇および下降する）。窓枠２には、実施の形態に係わる挟み込み検知スイッチ１が配設されている。窓ガラス３が上昇しているときに、物体（人体を含む）が窓枠２と窓ガラス３との間に挟まれると、挟み込み検知スイッチ１が、挟み込みを検知し、検知信号を制御装置２１に供給する。制御装置２１は、検知信号が所定の値に到達すると、例えば窓ガラス３の上昇を停止する。これにより、挟み込みにより怪我等が発生するのを防ぐことが可能である。また、物体が挟まれると、物体を引き抜く操作が一般的に行われるが、挟み込み検知スイッチは、引き抜きも検知する。特に、挟まれた物体が車内側ではなく、車外側に引き抜かれる場合は、安全性の観点から、引き抜きを検知することが重要である。 (Embodiment)
FIG. 6 is a schematic diagram showing the configuration of an automobile equipped with a pinch detection switch according to the embodiment. Here, an example in which the pinch detection switch is applied to a power window will be described. In FIG. 6, 2 indicates a window frame of the automobile 20. The window glass 3 is moved up and down by the electric actuator (up and down). The window frame 2 is provided with a pinching detection switch 1 according to the embodiment. When an object (including a human body) is sandwiched between the window frame 2 and the window glass 3 while the window glass 3 is raised, the sandwiching detection switch 1 detects the sandwiching and detects a detection signal. To supply. When the detection signal reaches a predetermined value, the control device 21 stops the window glass 3 from rising, for example. As a result, it is possible to prevent injuries and the like from being caught. Further, when an object is pinched, an operation of pulling out the object is generally performed, but the pinching detection switch also detects pulling out. In particular, when the sandwiched object is pulled out to the outside of the vehicle instead of the inside of the vehicle, it is important to detect the extraction from the viewpoint of safety.

FIG. 1 is a cross-sectional view of a pinch detection switch according to an embodiment. FIG. 2 is a perspective view showing a pinching detection switch according to the embodiment. 2A is a perspective view of the pinch detection switch 1, and FIG. 2B is a perspective view of the pressure-sensitive detection member 5-1 provided in the pinch detection switch 1. FIG. As shown in FIG. 2A, the pinching detection switch 1 includes three pressure-sensitive detection members 5-1 to 5-3. Since the configuration is the same, only one pressure-sensitive detection member 5-1 is shown in FIG. FIG. 1 is a cross-sectional view taken along the line AA in FIG.

挟み込み検知スイッチ１は、窓枠２の延在方向Ｙに沿って延在し、窓枠２に配設された変形可能なカバー部材４を備えている。図２に示すように、カバー部材４は、カバー部材４と同じ方向に延在する感圧検知部材５−１〜５−３を覆っている。また、カバー部材４は、カバー部材４と同じ方向に延在する中空部７を覆っている。挟み込み検知スイッチ１のカバー部材４は、例えばゴムによって形成されており、カバー部材４の一部分は、図１に示すように、窓枠２に埋め込まれている。   The pinch detection switch 1 includes a deformable cover member 4 that extends along the extending direction Y of the window frame 2 and is disposed on the window frame 2. As shown in FIG. 2, the cover member 4 covers the pressure sensitive detection members 5-1 to 5-3 extending in the same direction as the cover member 4. Further, the cover member 4 covers a hollow portion 7 extending in the same direction as the cover member 4. The cover member 4 of the pinching detection switch 1 is made of rubber, for example, and a part of the cover member 4 is embedded in the window frame 2 as shown in FIG.

図１に示すように断面視で見ると、カバー部材４は、窓枠２に接する厚いベース部４−１と、窓ガラス３の面３−１に対向し、変形する弾性の変形部４−２とを備えている。このベース部４−１と変形部４−２との間が、中空部７となっている。また、変形部４−２は、断面視で見たとき、ベース部４−１のベース面４−３と対向し、感圧検知部材５−１〜５−３を覆っている上面変形部４−２Ｕと、上面変形部４−２Ｕとベース部４−１とを連結するように、上面変形部４−２Ｕおよびベース部４−１と一体的に形成された側面変形部４−２Ｓとを備えている。   As shown in FIG. 1, when viewed in cross-section, the cover member 4 has a thick base portion 4-1 in contact with the window frame 2 and an elastic deforming portion 4 that faces and deforms the surface 3-1 of the window glass 3. 2 are provided. A hollow portion 7 is formed between the base portion 4-1 and the deformable portion 4-2. Moreover, the deformation | transformation part 4-2 faces the base surface 4-3 of the base part 4-1, when it sees by sectional view, and the upper surface deformation | transformation part 4 which has covered the pressure sensitive detection members 5-1 to 5-3. -2U, and a side surface deformation portion 4-2S formed integrally with the upper surface deformation portion 4-2U and the base portion 4-1, so as to connect the upper surface deformation portion 4-2U and the base portion 4-1. I have.

第１の感圧検知部材である感圧検知部材５−１は、カバー部材４の中心線ＣＬＩ上に、その中心点ＣＮＴ１が配置されるように、上面変形部４−２Ｕ内に埋設されている。また、第２の感圧検知部材である感圧検知部材５−２は、中心線ＣＬＩに対して一側（図１中では紙面右側）に位置した上面変形部４−２Ｕ内に埋設されている。さらに、第３の感圧検知部材である感圧検知部材５−３は、中心線ＣＬＩに対して他側（図１中では紙面左側）に位置した上面変形部４−２Ｕ内に埋設されている。中心線ＣＬＩと感圧検知部材５−２の中心点ＣＮＴ２とを結ぶ仮想直線ＩＭＬ１と、中心線ＣＬＩとの間の角度と、中心線ＣＬＩと感圧検知部材５−３の中心点ＣＮＴ３とを結ぶ仮想直線ＩＭＬ２と、中心線ＣＬＩとの間の角度とは、同じ角度α１である。特に制限されないが、角度α１は、４５度である。これにより、挟み込み検知スイッチ１は、中心線ＣＬＩを基準として、左右対称の上面変形部４−２Ｕおよび側面変形部４−２Ｓを備えていることになる。   The pressure-sensitive detection member 5-1 that is the first pressure-sensitive detection member is embedded in the upper surface deformation portion 4-2U so that the center point CNT1 is disposed on the center line CLI of the cover member 4. Yes. Further, the pressure-sensitive detection member 5-2 that is the second pressure-sensitive detection member is embedded in the upper surface deformed portion 4-2U that is located on one side (the right side in FIG. 1) with respect to the center line CLI. Yes. Furthermore, the pressure-sensitive detection member 5-3, which is the third pressure-sensitive detection member, is embedded in the upper surface deformation portion 4-2U located on the other side (the left side in FIG. 1) with respect to the center line CLI. Yes. An angle between an imaginary straight line IML1 connecting the center line CLI and the center point CNT2 of the pressure-sensitive detection member 5-2 and the center line CLI, and the center line CLI and the center point CNT3 of the pressure-sensitive detection member 5-3 are The angle between the connecting imaginary straight line IML2 and the center line CLI is the same angle α1. Although not particularly limited, the angle α1 is 45 degrees. As a result, the pinch detection switch 1 includes the top surface deforming part 4-2U and the side surface deforming part 4-2S that are symmetrical with respect to the center line CLI.

感圧検知部材５−１〜５−３は、挟み込みおよび引き抜きの際に、後述する受け部８に押し付けられて、潰れるように変形する。感圧検知部材５−１〜５−３が、受け部８に押し付けられた際に、感圧検知部材５−１〜５−３と受け部８との間に、上面変形部４−２Ｕの一部分がカバー部分として介在する。同図には、カバー部分が、符号４−４〜４−６で示されている。   The pressure-sensitive detection members 5-1 to 5-3 are pressed against a receiving portion 8 described later and deformed so as to be crushed when being sandwiched and pulled out. When the pressure sensitive detection members 5-1 to 5-3 are pressed against the receiving portion 8, the upper surface deformation portion 4-2U is interposed between the pressure sensitive detecting members 5-1 to 5-3 and the receiving portion 8. A part is interposed as a cover part. In the figure, the cover portions are indicated by reference numerals 4-4 to 4-6.

図１では、中心線ＣＬＩに対して一側が、自動車２０の車内側であり、中心線ＣＬＩに対して他側が、自動車２０の車外側である。物体を挟み込んだ場合、変形部４−２が変形し、感圧検知部材５−１が主に潰され、挟み込みが検知される。一方、車外側から物体を引き抜く操作が行われた場合には、変形部４−２が変形し、感圧検知部材５−２が主に潰され、車外側からの引き抜きが検知される。また、車内側から物体を引き抜く操作が行われた場合には、変形部４−２が変形し、感圧検知部材５−３が主に潰され、車内側からの引き抜きが検知される。   In FIG. 1, one side with respect to the center line CLI is the inside of the automobile 20, and the other side with respect to the center line CLI is the outside of the automobile 20. When an object is sandwiched, the deforming portion 4-2 is deformed, the pressure-sensitive detection member 5-1 is mainly crushed, and the sandwiching is detected. On the other hand, when an operation of pulling out an object from the outside of the vehicle is performed, the deforming portion 4-2 is deformed, the pressure sensitive detection member 5-2 is mainly crushed, and the pulling out from the outside of the vehicle is detected. Further, when an operation of pulling out an object from the inside of the vehicle is performed, the deforming portion 4-2 is deformed, the pressure sensitive detection member 5-3 is mainly crushed, and the pulling out from the inside of the vehicle is detected.

ベース部４−１には、変形部４−２が変形したとき、感圧検知部材５−１〜５−３を受ける受け部８が設けられている。受け部８の外形形状は、図１に示すように、ベース部４−１から上面変形部４−２Ｕに向かって面積が狭くなる台形形状をしている。すなわち、受け部８は、ベース部４−１と中空部７とが接するベース面４−３と平行した上面８−１と、上面８−１とベース面４−３とを連結する第１斜面８−２と、上面８−１とベース面４−３とを連結する第２斜面８−３とを備えている。受け部８は、上面変形部４−２Ｕに対向している上面８−１が、ベース面４−３に対向する底面よりも狭い台形形状であるため、第１斜面８−２および第２斜面８−３とベース面４−３との間の内角α２は、０度を超え、９０度未満となっている。   The base portion 4-1 is provided with a receiving portion 8 that receives the pressure sensitive detection members 5-1 to 5-3 when the deforming portion 4-2 is deformed. As shown in FIG. 1, the outer shape of the receiving portion 8 has a trapezoidal shape whose area becomes narrower from the base portion 4-1 toward the upper surface deformation portion 4-2 U. That is, the receiving portion 8 includes an upper surface 8-1 parallel to the base surface 4-3 where the base portion 4-1 and the hollow portion 7 are in contact, and a first inclined surface connecting the upper surface 8-1 and the base surface 4-3. 8-2, and a second slope 8-3 connecting the upper surface 8-1 and the base surface 4-3. Since the receiving portion 8 has a trapezoidal shape in which the upper surface 8-1 facing the upper surface deforming portion 4-2U is narrower than the bottom surface facing the base surface 4-3, the first inclined surface 8-2 and the second inclined surface The internal angle α2 between 8-3 and the base surface 4-3 is more than 0 degree and less than 90 degrees.

カバー部材４の中心線ＣＬＩは、受け部８の上面８−１の中心を通過しており、受け部８は、中心線ＣＬＩを基準として、図１に示すように左右対称の構造となっている。なお、受け部８も、カバー部材４と同様に、ゴムによって形成されている。   The center line CLI of the cover member 4 passes through the center of the upper surface 8-1 of the receiving portion 8, and the receiving portion 8 has a symmetrical structure as shown in FIG. 1 with respect to the center line CLI. Yes. The receiving portion 8 is also made of rubber, like the cover member 4.

挟み込みにより変形部４−２が変形すると、カバー部分４−４を介して、感圧検知部材５−１が、受け部８の上面８−１に押し付けられることになる。すなわち、受け部８の上面８−１が、感圧検知部材５−１に対向し、感圧検知部材５−１の受け面として作用する。これに対して、車外側からの引き抜きにより変形部４−２が変形すると、カバー部分４−５を介して、感圧検知部材５−２が、受け部８の第１斜面８−２に押し付けられることになる。すなわち、受け部８の第１斜面８−２が、感圧検知部材５−２に対向し、感圧検知部材５−２の受け面として作用する。さらに、車内側からの引き抜きにより変形部４−２が変形すると、カバー部分４−６を介して、感圧検知部材５−３が、受け部８の第２斜面８−３に押し付けられることになる。すなわち、受け部８の第２斜面８−３が、感圧検知部材５−３に対向し、感圧検知部材５−３の受け面として作用する。   When the deforming portion 4-2 is deformed by the sandwiching, the pressure-sensitive detection member 5-1 is pressed against the upper surface 8-1 of the receiving portion 8 through the cover portion 4-4. That is, the upper surface 8-1 of the receiving portion 8 faces the pressure-sensitive detection member 5-1, and acts as a receiving surface for the pressure-sensitive detection member 5-1. On the other hand, when the deforming portion 4-2 is deformed by being pulled out from the outside of the vehicle, the pressure-sensitive detection member 5-2 is pressed against the first inclined surface 8-2 of the receiving portion 8 through the cover portion 4-5. Will be. That is, the 1st slope 8-2 of the receiving part 8 opposes the pressure-sensitive detection member 5-2, and acts as a receiving surface of the pressure-sensitive detection member 5-2. Further, when the deforming portion 4-2 is deformed by being pulled out from the inside of the vehicle, the pressure-sensitive detection member 5-3 is pressed against the second inclined surface 8-3 of the receiving portion 8 through the cover portion 4-6. Become. That is, the second inclined surface 8-3 of the receiving portion 8 faces the pressure-sensitive detection member 5-3 and acts as a receiving surface for the pressure-sensitive detection member 5-3.

感圧検知部材５−１は、図２（Ｂ）に示すように、離間された電極線ＥＤ１〜ＥＤ４を有する管状の検知部材である。感圧検知部材５−１は、離間された電極線ＥＤ１〜ＥＤ４を囲む部材が弾力性を有しており、外力が加わることにより、電極線ＥＤ１〜ＥＤ４間の離間距離が変わるように中空部６−１が変形する。感圧検知部材を構成する複数の電極線は、感圧検知部材の長手方向に沿って螺旋状に形成されている。これにより、感圧検知部材の径方向における全方位からの外力に対して検知可能となっている。離間距離が変わることにより、電極線ＥＤ１〜ＥＤ４間の電気抵抗が変化する。電極線ＥＤ１〜ＥＤ４間の電気抵抗の変化が検知信号の値として、図６に示した制御装置２１に供給される。感圧検知部材５−２、５−３も、感圧検知部材５−１と同様に、中空部６−２、６−３と電極線ＥＤ１〜ＥＤ４を備えている。この感圧検知部材５−１は、上記した特許文献２に示されている管状部材と同じであるため、これ以上の詳しい説明は省略する。   As shown in FIG. 2B, the pressure-sensitive detection member 5-1 is a tubular detection member having electrode lines ED1 to ED4 spaced apart from each other. The pressure-sensitive detection member 5-1 is a hollow portion so that the members surrounding the separated electrode wires ED1 to ED4 have elasticity, and the separation distance between the electrode wires ED1 to ED4 changes when an external force is applied. 6-1 is deformed. The plurality of electrode wires constituting the pressure sensitive detection member are formed in a spiral shape along the longitudinal direction of the pressure sensitive detection member. Thereby, it can detect with respect to the external force from all the directions in the radial direction of a pressure-sensitive detection member. The electrical resistance between the electrode lines ED1 to ED4 changes as the separation distance changes. The change in electrical resistance between the electrode lines ED1 to ED4 is supplied to the control device 21 shown in FIG. 6 as the value of the detection signal. The pressure sensitive detection members 5-2 and 5-3 also include hollow portions 6-2 and 6-3 and electrode wires ED1 to ED4, similarly to the pressure sensitive detection member 5-1. Since this pressure-sensitive detection member 5-1 is the same as the tubular member shown in Patent Document 2 described above, further detailed description is omitted.

後で図４を用いて説明するが、感圧検知部材５−１は、挟み込みにより、受け部８の上面８−１に向かって移動し、潰されるように変形する。感圧検知部材５−１が潰されることにより、上記した検知信号により挟み込みが検知される。このときの検知感度は、変形部４−２が変形していないときのカバー部分４−４と受け部８の上面８−１との間の距離Ｌ１によって定めることができる。この場合、距離Ｌ１を短くする程、検知感度を高くすることができる。   As will be described later with reference to FIG. 4, the pressure-sensitive detection member 5-1 moves toward the upper surface 8-1 of the receiving portion 8 and is deformed so as to be crushed. When the pressure-sensitive detection member 5-1 is crushed, pinching is detected by the detection signal described above. The detection sensitivity at this time can be determined by the distance L1 between the cover portion 4-4 and the upper surface 8-1 of the receiving portion 8 when the deforming portion 4-2 is not deformed. In this case, the detection sensitivity can be increased as the distance L1 is shortened.

また、後で図５を用いて説明するが、感圧検知部材５−２は、車外側への引き抜きにより、受け部８の第１斜面８−２に向かって移動し、潰されるように変形する。このときの検知信号により引き抜きが検知される。引き抜きの検知感度は、変形部４−２が変形していないときのカバー部分４−５と受け部８の第１斜面８−２との間の距離Ｌ２と、内角α２によって定めることができる。同様に、感圧検知部材５−３は、車内側への引き抜きにより、受け部８の第２斜面８−３に向かって移動し、潰されるように変形する。このときの検知信号により引き抜きが検知される。引き抜きの検知感度は、変形部４−２が変形していないときのカバー部分４−６と受け部８の第２斜面８−３との間の距離Ｌ３と、内角α２によって定めることができる。車内側への引き抜きおよび車外側への引き抜きのいずれの場合も、距離Ｌ２およびＬ３を短くする程、検知感度を高くすることができる。また、内角α２を９０度に近づける程、検知感度を高くすることができる。   Further, as will be described later with reference to FIG. 5, the pressure-sensitive detection member 5-2 moves toward the first inclined surface 8-2 of the receiving portion 8 and is deformed so as to be crushed by being pulled out to the outside of the vehicle. To do. Extraction is detected by the detection signal at this time. The pulling detection sensitivity can be determined by the distance L2 between the cover portion 4-5 and the first inclined surface 8-2 of the receiving portion 8 when the deforming portion 4-2 is not deformed, and the inner angle α2. Similarly, the pressure-sensitive detection member 5-3 moves toward the second inclined surface 8-3 of the receiving portion 8 and is deformed so as to be crushed by being pulled out to the inside of the vehicle. Extraction is detected by the detection signal at this time. The pulling detection sensitivity can be determined by the distance L3 between the cover portion 4-6 and the second inclined surface 8-3 of the receiving portion 8 when the deforming portion 4-2 is not deformed, and the inner angle α2. In both cases of pulling out to the inside of the vehicle and pulling out to the outside of the vehicle, the detection sensitivity can be increased as the distances L2 and L3 are shortened. In addition, the detection sensitivity can be increased as the inner angle α2 approaches 90 degrees.

なお、実施の形態では、第１斜面８−２によって形成される内角α２と第２斜面８−３によって形成される内角α２が同じ場合を例として説明したが、これに限定されるものではない。すなわち、第１斜面８−２によって形成される内角α２は、第２斜面８−３によって形成される内角α２と異なっていてもよい。それぞれの斜面によって形成される内角α２を変えることにより、車外側からの引き抜きに対する検知感度と車内側からの引き抜きに対する検知感度を異なるようにすることも可能である。   In the embodiment, the case where the inner angle α2 formed by the first inclined surface 8-2 and the inner angle α2 formed by the second inclined surface 8-3 are the same has been described as an example, but the present invention is not limited to this. . That is, the inner angle α2 formed by the first inclined surface 8-2 may be different from the inner angle α2 formed by the second inclined surface 8-3. By changing the inner angle α2 formed by each slope, it is possible to make the detection sensitivity for pulling out from the outside of the vehicle different from the detection sensitivity for pulling out from the inside of the vehicle.

挟み込みおよび引き抜きの検知の際には、受け部８の上面８−１、第１斜面８−２または第２斜面８−３が、カバー部分４−４，４−５または４−６の表面と接することになる。感圧検知部材５−１〜５−３をより変形し易く（潰し易く）するためには、カバー部分４−４，４−５または４−６の表面と感圧検知部材５−１〜５−３の表面との間に介在しているカバー部材４の肉厚を、感圧検知部材５−１〜５−３の表面と変形部４−２の外側表面との間に介在しているカバー部材４の肉厚よりも薄くすることが望ましい。   At the time of detecting pinching and pulling, the upper surface 8-1, the first inclined surface 8-2, or the second inclined surface 8-3 of the receiving portion 8 is in contact with the surface of the cover portions 4-4, 4-5, or 4-6. Will be in touch. In order to make the pressure-sensitive detection members 5-1 to 5-3 more easily deformable (easy to be crushed), the surface of the cover portion 4-4, 4-5 or 4-6 and the pressure-sensitive detection members 5-1 to 5-5. The thickness of the cover member 4 interposed between the surfaces of the pressure-sensitive detection members 5-1 to 5-3 and the outer surfaces of the deformable portions 4-2 It is desirable to make it thinner than the thickness of the cover member 4.

＜台形形状の受け部８＞
実施の形態によれば、受け部８の外形形状は台形形状とされる。これにより、挟み込みまたは引き抜きにより、変形部４−２が変形したとき、圧力が受け部８によって吸収されるのを低減し、感圧検知部材５−１〜５−３に加わる外力を大きくすることが可能である。 <Trapezoidal receiving part 8>
According to the embodiment, the outer shape of the receiving portion 8 is a trapezoidal shape. Thereby, when the deformation | transformation part 4-2 deform | transforms by pinching or drawing | extracting, it reduces that a pressure is absorbed by the receiving part 8, and enlarges the external force added to the pressure-sensitive detection members 5-1 to 5-3. Is possible.

図３は、実施の形態に係わる受け部を説明するための図である。ここでは、受け部８として、外形形状が直方体形状の受け部を用いた場合と、実施の形態のように外形形状が台形形状の受け部を用いた場合を、比較して、説明する。   FIG. 3 is a diagram for explaining a receiving unit according to the embodiment. Here, the case where a rectangular parallelepiped receiving portion is used as the receiving portion 8 and the case where a trapezoidal receiving portion is used as in the embodiment will be described in comparison.

図３（Ａ）および（Ｂ）は、挟み込みの場合を説明する図であり、図３（Ｃ）および（Ｄ）は、引き抜きの場合を説明する図である。図３（Ａ）および（Ｃ）は、受け部８を直方体形状にした場合であり、図３（Ｂ）および（Ｄ）は、受け部８を台形形状にした場合である。   FIGS. 3A and 3B are diagrams for explaining the case of pinching, and FIGS. 3C and 3D are diagrams for explaining the case of pulling out. FIGS. 3A and 3C show a case where the receiving portion 8 has a rectangular parallelepiped shape, and FIGS. 3B and 3D show a case where the receiving portion 8 has a trapezoidal shape.

挟み込みが発生すると、変形部が変形し、図１に示した感圧検知部材５−１がカバー部分４−４を介して、受け部８の上面８−１に押し付けられる。これにより、受け部８の上面８−１に外力ＳＴＲ１が加わることになる。直方体形状の受け部の場合、図３（Ａ）の紙面右側に示すように、外力ＳＴＲ１によって、受け部８の中腹部が膨らむようにして、直方体の受け部８は、ベース面４−３に向かって潰されてしまう。すなわち、外力ＳＴＲ１は、受け部８が潰れることにより、吸収され、感圧検知部材５−１に加わる圧力が減ってしまう。これに対して、台形形状の受け部８の場合、外力ＳＴＲ１は台形形状の広い底面に分散され、図３（Ｂ）の紙面右側に示すように、受け部８の中腹部が膨らむのを低減することが可能である。これにより、受け部８の受け面である上面８−１が、ベース面４−３に向かって潰されるのを低減し、外力ＳＴＲ１が、受け部８によって吸収されるのを低減することができる。その結果として、感圧検知部材に５−１に加わる外力を大きくすることができる。   When pinching occurs, the deforming portion is deformed, and the pressure-sensitive detection member 5-1 shown in FIG. 1 is pressed against the upper surface 8-1 of the receiving portion 8 via the cover portion 4-4. As a result, the external force STR1 is applied to the upper surface 8-1 of the receiving portion 8. In the case of a rectangular parallelepiped shaped receiving portion, as shown on the right side of the sheet of FIG. 3 (A), the abdominal portion of the receiving portion 8 is expanded by the external force STR1, and the rectangular parallelepiped receiving portion 8 is formed on the base surface 4-3. It will be crushed. That is, the external force STR1 is absorbed when the receiving portion 8 is crushed, and the pressure applied to the pressure-sensitive detection member 5-1 is reduced. On the other hand, in the case of the trapezoidal receiving portion 8, the external force STR1 is dispersed on the wide bottom surface of the trapezoidal shape, and the swelling of the middle part of the receiving portion 8 is reduced as shown on the right side of FIG. 3B. Is possible. Thereby, it can reduce that upper surface 8-1 which is a receiving surface of the receiving part 8 is crushed toward the base surface 4-3, and can reduce that external force STR1 is absorbed by the receiving part 8. FIG. . As a result, the external force applied to the pressure sensitive detection member 5-1 can be increased.

次に、車外側への引き抜きが発生した場合を説明する。車外側への引き抜きは、車内側から外力ＳＴＲ２が加わったことで模擬することができる。   Next, a case where the vehicle is pulled out to the outside will be described. Pulling out to the outside of the vehicle can be simulated by applying an external force STR2 from the inside of the vehicle.

図３（Ｃ）の紙面右側に示すように、直方体形状の受け部８では、外力ＳＴＲ２の方向に、受け部８が傾き、外力ＳＴＲ２に対して直方体が逃げるように変形する。外力ＳＴＲ２は、この変形により吸収され、感圧検知部材５−２に加わる外力が減ってしまう。   As shown on the right side of FIG. 3C, the rectangular parallelepiped receiving portion 8 is deformed so that the receiving portion 8 is inclined in the direction of the external force STR2 and the rectangular parallelepiped escapes with respect to the external force STR2. The external force STR2 is absorbed by this deformation, and the external force applied to the pressure sensing member 5-2 is reduced.

これに対して、台形形状の受け部８では、第１斜面８−２とは反対側の第２斜面８−３が外力ＳＴＲ２に対抗するように支えとして作用し、受け部８は変形し難くなる。その結果、受け部８が変形することにより外力ＳＴＲ２が吸収されるのを減らし、感圧検知部材５−２に加わる外力を大きくすることができる。   On the other hand, in the trapezoidal receiving portion 8, the second inclined surface 8-3 opposite to the first inclined surface 8-2 acts as a support so as to oppose the external force STR2, and the receiving portion 8 is hardly deformed. Become. As a result, the deformation of the receiving portion 8 can reduce the absorption of the external force STR2, and can increase the external force applied to the pressure sensitive detection member 5-2.

ここでは、車外側への引き抜きを例として説明したが、車内側への引き抜きのときも同様にして、感圧検知部材５−３に加わる外力を大きくすることができる。   Although the drawing to the outside of the vehicle has been described here as an example, the external force applied to the pressure-sensitive detection member 5-3 can be increased in the same manner when drawing to the inside of the vehicle.

このように、台形形状の受け部８を用いることにより、挟み込みおよび引き抜きの際に、感圧検知部材５−１〜５−３に加わる外力を大きくすることができるため、検知感度を高くすることが可能である。   In this way, by using the trapezoidal receiving portion 8, it is possible to increase the external force applied to the pressure sensitive detection members 5-1 to 5-3 at the time of pinching and pulling out, so that the detection sensitivity is increased. Is possible.

次に、挟み込みおよび引き抜きのときの挟み込み検知スイッチ１の状態を説明する。図４および図５は、実施の形態に係わる挟み込み検知スイッチの状態を示す断面図である。先ず、図４を用いて、挟み込みのときを説明する。   Next, the state of the pinch detection switch 1 when pinching and pulling out will be described. 4 and 5 are sectional views showing a state of the pinching detection switch according to the embodiment. First, the case of pinching will be described with reference to FIG.

＜挟み込み＞
図４には、図示しない物体を挟み込んだときの挟み込み検知スイッチ１の状態が示されている。 <Pinch>
FIG. 4 shows a state of the pinching detection switch 1 when an object (not shown) is pinched.

図４において、二点鎖線は、物体を挟み込んでいないときの変形部４−２の初期状態を示している。物体を挟み込むことにより、変形部４−２が変形する。この場合、上面変形部４−２Ｕは、受け部８の上面８−１の方向に移動するように変形し、側面変形部４−２Ｓは、紙面において左右に膨らむように変形する。   In FIG. 4, a two-dot chain line indicates an initial state of the deforming portion 4-2 when no object is sandwiched. By inserting the object, the deforming portion 4-2 is deformed. In this case, the upper surface deforming part 4-2U is deformed so as to move in the direction of the upper surface 8-1 of the receiving part 8, and the side surface deforming part 4-2S is deformed so as to swell left and right on the paper surface.

上面変形部４−２Ｕが、上面８−１の方向に移動することにより、カバー部分４−４を介して感圧検知部材５−１が、対向する上面８−１に押し付けられ、感圧検知部材５−１は、潰れるように変形される。図６に示した制御装置２１は、例えば感圧検知部材５−１が図４に示した状態になっているときの検知信号の値で、挟み込みがあると検知する。   When the upper surface deforming part 4-2U moves in the direction of the upper surface 8-1, the pressure-sensitive detection member 5-1 is pressed against the upper surface 8-1 facing the cover portion 4-4 to detect pressure. The member 5-1 is deformed so as to be crushed. The control device 21 shown in FIG. 6 detects the presence of pinching, for example, based on the value of the detection signal when the pressure-sensitive detection member 5-1 is in the state shown in FIG.

＜引き抜き＞
図５には、図示しない物体を引き抜く操作が行われたときの状態が示されている。ここでは、車外側から物体を引き抜く操作が行われた場合を説明する。引き抜く操作が行われる前の変形部４−２の状態は、例えば図４において二点鎖線で示した初期状態である。 <Pull out>
FIG. 5 shows a state when an operation for pulling out an object (not shown) is performed. Here, a case where an operation of pulling out an object from the outside of the vehicle is performed will be described. The state of the deforming part 4-2 before the pulling-out operation is performed is, for example, an initial state indicated by a two-dot chain line in FIG.

引き抜く操作では、物体が、変形部４−２の上面変形部４−２Ｕにおいて、紙面右側の部分と接触し、物体は、上面変形部４−２Ｕを紙面左側へ移動させるように、変形部４−２を変形させる。上面変形部４−２Ｕが紙面左側へ移動するように変形するため、側面変形部４−２Ｓも、紙面左側へ傾くように変形する。   In the pulling-out operation, the object comes into contact with the right side portion of the paper surface in the upper surface deformation portion 4-2U of the deformation portion 4-2, and the object moves the upper surface deformation portion 4-2U to the left side of the paper surface. -2 is deformed. Since the upper surface deforming part 4-2U is deformed so as to move to the left side of the sheet, the side surface deforming part 4-2S is also deformed so as to be inclined to the left side of the sheet.

上面変形部４−２Ｕが紙面左側へ移動させられるため、車内側に配置されている感圧検知部材５−２が、図５に示すように、受け部８の第１斜面８−２に当接し、カバー部分４−５を介して感圧検知部材５−２が、対向する第１斜面８−２に押し付けられ、潰されるように変形する。図６に示した制御装置２１は、例えば感圧検知部材５−２が図５に示した状態になっているときの検知信号の値で、車外側からの引き抜きがあると検知する。   Since the upper surface deforming part 4-2U is moved to the left side of the page, the pressure-sensitive detection member 5-2 disposed on the inner side of the vehicle contacts the first inclined surface 8-2 of the receiving part 8 as shown in FIG. The pressure-sensitive detection member 5-2 is pressed against the opposed first inclined surface 8-2 via the cover portion 4-5, and is deformed so as to be crushed. The control device 21 shown in FIG. 6 detects, for example, that there is an extraction from the outside of the vehicle, based on the value of the detection signal when the pressure sensitive detection member 5-2 is in the state shown in FIG.

車外側から引き抜きが行われた場合を説明したが、車内側から引き抜きが行われた場合も同様である。すなわち、車内側からの引き抜き操作に対しては、車外側に配置した感圧検知部材５−３が潰されるように変形する。   Although the case where the drawing is performed from the outside of the vehicle has been described, the same applies to the case where the drawing is performed from the inside of the vehicle. That is, with respect to the pulling-out operation from the inside of the vehicle, the pressure-sensitive detection member 5-3 disposed on the outside of the vehicle is deformed so as to be crushed.

このように、実施の形態に係わる挟み込み検知スイッチ１は、挟み込みと引き抜きの両方を適切に検知することが可能である。また、カバー部材４には中空部７が設けられているため、クッション性を高めることが可能である。   As described above, the pinch detection switch 1 according to the embodiment can appropriately detect both pinching and drawing. Moreover, since the hollow part 7 is provided in the cover member 4, it is possible to improve cushioning properties.

実施の形態においては、図１に示したように、上面変形部４−２Ｕの肉厚４Ａに比べて側面変形部４−２Ｓの肉厚４Ｂが薄くなっている。そのため、挟み込みおよび引き抜きが発生した場合、側面変形部４−２Ｓが変形し易くなっており、検知感度を高めることができる。   In the embodiment, as shown in FIG. 1, the wall thickness 4B of the side surface deformation portion 4-2S is thinner than the wall thickness 4A of the upper surface deformation portion 4-2U. Therefore, when pinching and extraction occur, the side deformation part 4-2S is easily deformed, and the detection sensitivity can be increased.

＜変形例＞
以下、複数の変形例を述べる。 <Modification>
Hereinafter, a plurality of modifications will be described.

第１の変形例に係わる挟み込み検知スイッチにおいては、上記した感圧検知部材５−３が削除されている。すなわち、上面変形部４−２Ｕには、主に挟み込みを検知する感圧検知部材５−１と、主に車外側からの引き抜きを検知する感圧検知部材５−２のみが配置されている。これにより、挟み込み検知スイッチの価格を抑制することが可能である。   In the pinching detection switch according to the first modification, the pressure-sensitive detection member 5-3 described above is deleted. That is, only the pressure-sensitive detection member 5-1 that mainly detects the pinching and the pressure-sensitive detection member 5-2 that mainly detects the pull-out from the outside of the vehicle are disposed in the upper surface deformation portion 4-2U. Thereby, the price of the pinch detection switch can be suppressed.

第２の変形例に係わる挟み込み検知スイッチにおいては、受け部８の上面８−１、第１斜面８−２および第２斜面８−３のうちの少なくとも１つに、凸部が配置される。この凸部は、上面変形部４−２Ｕに向かって突出した形状を備えている。この凸部によって、感圧検知部材をより潰し易くすることが可能である。   In the pinching detection switch according to the second modification, a convex portion is disposed on at least one of the upper surface 8-1, the first slope 8-2, and the second slope 8-3 of the receiving portion 8. This convex part is provided with the shape which protruded toward the upper surface deformation | transformation part 4-2U. This convex portion can make the pressure-sensitive detection member easier to crush.

また、第２の変形例においては、凸部が、上面８−１、第１斜面８−２および第２斜面８−３において、帯状となっている。上面８−１を例にして述べると、上面８−１には、カバー部材４の延在方向（図２のＹ方向）と同じ方向に延在した凸部が設けられている。これにより、上面８−１では、凸部が設けられている部分と、設けられていない部分とによって、帯状の凸凹が形成されることになる。第１斜面８−２および第２斜面８−３も、上記した上面８−１と同様である。このような帯状の凸部は、例えば押出形成により容易に形成することが可能である。   Moreover, in the 2nd modification, the convex part becomes strip | belt shape in the upper surface 8-1, the 1st slope 8-2, and the 2nd slope 8-3. To describe the upper surface 8-1 as an example, the upper surface 8-1 is provided with a convex portion extending in the same direction as the extending direction of the cover member 4 (Y direction in FIG. 2). Thereby, in the upper surface 8-1, a strip-shaped unevenness is formed by a portion where the convex portion is provided and a portion where the convex portion is not provided. The first inclined surface 8-2 and the second inclined surface 8-3 are the same as the upper surface 8-1. Such a belt-like convex portion can be easily formed by, for example, extrusion.

さらに、凸部は、受け部８と一体的に形成してもよいし、凸部を、受け部８とは別に準備し、受け部８の面に設けるようにしてもよい。   Furthermore, the convex portion may be formed integrally with the receiving portion 8, or the convex portion may be prepared separately from the receiving portion 8 and provided on the surface of the receiving portion 8.

第３の変形例に係わる挟み込み検知スイッチにおいては、感圧検知部材５−１〜５−３が、カバー部材４とは別に準備される。カバー部材４には、断面視で見たとき、感圧検知部材５−１〜５−３の断面積よりも大きな面積の挿入口が形成される。別途準備した感圧検知部材５−１〜５−３を、カバー部材４において対応する挿入口に挿入する。これにより、対応する挿入口に感圧検知部材５−１〜５−３を挿入する際に、感圧検知部材５−１〜５−３が捩れるのを防ぐことが可能である。   In the pinching detection switch according to the third modification, pressure-sensitive detection members 5-1 to 5-3 are prepared separately from the cover member 4. The cover member 4 is formed with an insertion opening having an area larger than the cross-sectional area of the pressure-sensitive detection members 5-1 to 5-3 when viewed in a cross-sectional view. Separately prepared pressure-sensitive detection members 5-1 to 5-3 are inserted into corresponding insertion openings in the cover member 4. Thereby, when inserting the pressure sensitive detection members 5-1 to 5-3 into the corresponding insertion ports, it is possible to prevent the pressure sensitive detection members 5-1 to 5-3 from being twisted.

また、第３の変形例においては、感圧検知部材５−１〜５−３の断面が、楕円形にされる。さらに、挿入口に接着剤を入れ、円形または楕円形の感圧検知部材５−１〜５−３が対応する挿入口に挿入される。   Moreover, in the 3rd modification, the cross section of the pressure sensitive detection members 5-1 to 5-3 is made into an ellipse. Furthermore, an adhesive is put into the insertion port, and circular or elliptical pressure-sensitive detection members 5-1 to 5-3 are inserted into the corresponding insertion ports.

実施の形態に係わる受け部８は、カバー部材４と同様にゴムで形成されているが、受け部８は、カバー部材４と一体であっても、別体であってもよい。同様に、感圧検知部材５−１〜５−３も、カバー部材４と一体であってもよいし、第３の変形例で述べたように別体であってもよい。   Although the receiving portion 8 according to the embodiment is formed of rubber like the cover member 4, the receiving portion 8 may be integrated with the cover member 4 or may be a separate body. Similarly, the pressure sensitive detection members 5-1 to 5-3 may be integrated with the cover member 4 or may be separate bodies as described in the third modification.

尚、実施の形態においては、上面８−１、第１斜面８−２および第２斜面８−３は平坦な面であるが、本発明の効果を奏する限りにおいて、上面８−１、第１斜面８−２および第２斜面８−３は平面に限らず、曲面であってもよい。   In the embodiment, the upper surface 8-1, the first inclined surface 8-2, and the second inclined surface 8-3 are flat surfaces. However, as long as the effects of the present invention are achieved, the upper surface 8-1, The slope 8-2 and the second slope 8-3 are not limited to planes, and may be curved surfaces.

以上、本発明者によってなされた発明を実施の形態に基づき具体的に説明したが、本発明は前記実施の形態に限定されるものではなく、その要旨を逸脱しない範囲で種々変更可能であることはいうまでもない。例えば、実施の形態では、自動車を適用対象として説明したが、適用対象は、自動車に限定されず、鉄道の電車、ホームドア、エレベータあるいはバックドア等でもよい。   As mentioned above, the invention made by the present inventor has been specifically described based on the embodiment. However, the present invention is not limited to the embodiment, and various modifications can be made without departing from the scope of the invention. Needless to say. For example, in the embodiment, the description has been given with the automobile being the application target, but the application target is not limited to the automobile, and may be a railroad train, a home door, an elevator, a back door, or the like.
