Description

本発明は、ゴム等の弾性材料で構成され、一方のパネルと当該一方のパネルに対して回転自在に設けられた他方のパネルとの間に掛け渡されるワイヤハーネスを内側に収容するグロメットに関する。   The present invention relates to a grommet that is made of an elastic material such as rubber and accommodates a wire harness that is spanned between one panel and the other panel that is rotatably provided to the one panel.

移動体としての自動車には、一般にヘッドランプ及びテールランプ等のランプ類、スタータモータ及びエアコンディショナ用のモータ等のモータ類等の多種多様な電子機器が搭載されている。前述した電子機器に電力を供給するために、前記自動車はワイヤハーネスを配索している。   A variety of electronic devices such as lamps such as head lamps and tail lamps, and motors such as motors for starter motors and air conditioners are generally mounted on automobiles as moving bodies. In order to supply electric power to the electronic device described above, the automobile has a wire harness.

ワイヤハーネスは、互いに束ねられた複数の電線と、これら電線の端末等に取り付けられたコネクタ等を備えている。このようなワイヤハーネスは、自動車の車体を構成する車体パネルと、この車体パネルに対して回転自在に設けられたトランクパネルとに亘って掛け渡されることがあり、この掛け渡されたワイヤハーネスを保護するために従来から種々のグロメット（例えば、特許文献１参照）が用いられている。   The wire harness includes a plurality of electric wires bundled with each other and connectors attached to ends of these electric wires. Such a wire harness may be stretched over a vehicle body panel constituting a vehicle body of a car and a trunk panel provided rotatably with respect to the vehicle body panel. Conventionally, various grommets (for example, refer to Patent Document 1) are used for protection.

この特許文献１に記載されたグロメットは、ゴム等の弾性材料で構成されたグロメット本体と、合成樹脂等のグロメット本体よりも硬質な材料で構成された保持部材とを別体に備えている。   The grommet described in Patent Document 1 includes a grommet body made of an elastic material such as rubber and a holding member made of a material harder than the grommet body such as synthetic resin.

グロメット本体は、前述した車体パネルとトランクパネルとのそれぞれに設けられた孔内に嵌合する筒状の一対の嵌合筒部と、これら一対の嵌合筒部同士を連結した筒状の連結筒部とを一体に備えている。連結筒部は、各嵌合筒部に連なった円筒状でかつ前記嵌合筒部よりも小径の一対の小径筒部と、各小径筒部に連なった蛇腹状の一対の蛇腹筒部と、これら蛇腹筒部同士を連結した円筒状の中央筒部とを備えている。中央筒部両端の外周面には、それぞれ、環状のストッパが突出している。   The grommet body includes a pair of cylindrical fitting cylinders that fit into holes provided in the vehicle body panel and the trunk panel, and a cylindrical connection in which the pair of fitting cylinders are connected to each other. A cylindrical portion is provided integrally. The connecting cylinder part is a cylindrical shape connected to each fitting cylinder part and a pair of small diameter cylinder parts smaller in diameter than the fitting cylinder part, and a pair of bellows-like bellows cylinder parts connected to each small diameter cylinder part, And a cylindrical central tube portion connecting these bellows tube portions. Annular stoppers protrude from the outer peripheral surfaces at both ends of the central cylinder part.

保持部材は、円筒状の円筒部と、円筒部の外周面から突出した取付部とを備えている。円筒部は、開閉及び係止可能に形成され、前述したストッパ間に位置付けられて中央筒部の外周に取り付けられる。取付部は、前述した車体パネルとトランクパネルを連結したヒンジ部に取付可能な形状に形成されている。   The holding member includes a cylindrical cylindrical portion and an attachment portion protruding from the outer peripheral surface of the cylindrical portion. The cylindrical portion is formed to be openable and closable, and is positioned between the stoppers described above and attached to the outer periphery of the central cylindrical portion. The attachment portion is formed in a shape that can be attached to a hinge portion connecting the vehicle body panel and the trunk panel.

前述したグロメットは、一方の嵌合筒部と連結筒部と他方の嵌合筒部とに亘って、即ち全長に亘って筒状に形成され、内側にワイヤハーネスを通す。そして、グロメットは、一方の嵌合筒部が車体パネルとトランクパネルとのうちの一方に設けられた孔内に嵌合し、他方の嵌合筒部が車体パネルとトランクパネルとのうちの他方に設けられた孔内に嵌合して、ワイヤハーネスを車体パネルとトランクパネルとに亘って配索する。   The above-described grommet is formed in a tubular shape over one fitting tube portion, the connecting tube portion, and the other fitting tube portion, that is, over the entire length, and passes the wire harness inside. In the grommet, one fitting tube portion is fitted in a hole provided in one of the vehicle body panel and the trunk panel, and the other fitting tube portion is the other of the vehicle body panel and the trunk panel. The wire harness is routed between the vehicle body panel and the trunk panel.

さらに、グロメットは、保持部材の円筒部がグロメット本体の中央筒部に取り付けられかつ取付部が前述したヒンジ部に取り付けられて、トランクパネルが車体パネルに対して回転し連結筒部が曲がったり伸ばされたりする際に、連結筒部の曲がる方向（形状）を規制している。そして、グロメットは、保持部材によって、連結筒部が車体パネルに取り付けられた周辺部品、車体パネルやトランクパネル等に接触して破損することを防止している。   Further, the grommet has a cylindrical part of the holding member attached to the central cylinder part of the grommet body and an attachment part attached to the hinge part described above, so that the trunk panel rotates with respect to the vehicle body panel and the connecting cylinder part is bent or stretched. When this occurs, the bending direction (shape) of the connecting tube portion is regulated. And the grommet is preventing the connection cylinder part from contacting with the peripheral components attached to the vehicle body panel, the vehicle body panel, the trunk panel, etc., and being damaged by the holding member.

Then, the wire harness 93 (indicated by a two-dot chain line in FIG. 1) routed through the above-described automobile is passed inside. The grommet body 2 is fixed to the wire harness 93 by winding a tape around the outer periphery of the harness fixing piece 22 a and the wire harness 93 and by winding a tape around the outer periphery of the outer small diameter cylindrical portion 21 a and the wire harness 93. In the grommet main body 2, one fitting tube portion 21, that is, one end portion 2 a is fitted into the hole 91 a of the vehicle body panel 91, and the other fitting tube portion 22, that is, the other end portion 2 b is formed in the hole 92 a of the trunk panel 92. The wire harness 93 is routed across the vehicle body panel 91 and the trunk panel 92 by being fitted inside.

プロテクタ３は、合成樹脂等で構成され、グロメット本体２よりも硬質な材料で構成されている。プロテクタ３は、図１に示すように、グロメット本体２の蛇腹筒部２５の外周に取り付けられる。プロテクタ３は、図２に示すように、一方の取付部としての半円筒部３１と、他方の取付部としてのバンド部３２と、これら半円筒部３１の周方向の一端部３１ａとバンド部３２の長手方向の一端部３２ａとを互いに連結する連結部３３とを一体に備えている。   The protector 3 is made of a synthetic resin or the like, and is made of a material harder than the grommet body 2. The protector 3 is attached to the outer periphery of the bellows cylinder part 25 of the grommet main body 2 as shown in FIG. As shown in FIG. 2, the protector 3 includes a semi-cylindrical part 31 as one attaching part, a band part 32 as the other attaching part, and one end part 31 a and a band part 32 in the circumferential direction of the semi-cylindrical part 31. Are integrally provided with a connecting portion 33 that connects the end portions 32a in the longitudinal direction.

半円筒部３１は、半円筒状（樋状）に形成され、蛇腹筒部２５の最大外径と略同一曲率で湾曲している。半円筒部３１は、内面３１ｃが前述した回転中心Ｐから離れた側の蛇腹筒部２５の外周面に重ねられて、内側に蛇腹筒部２５を位置付ける。半円筒部３１には、突部としてのリブ３４と、係合部としてのロック部３５とが設けられている。   The semi-cylindrical portion 31 is formed in a semi-cylindrical shape (a bowl shape) and is curved with substantially the same curvature as the maximum outer diameter of the bellows tube portion 25. The semi-cylindrical portion 31 has the inner surface 31c overlapped with the outer peripheral surface of the bellows tube portion 25 on the side away from the rotation center P described above, and positions the bellows tube portion 25 inside. The semi-cylindrical portion 31 is provided with a rib 34 as a projecting portion and a lock portion 35 as an engaging portion.

リブ３４は、半円筒部３１の蛇腹筒部２５に重ねられる内面（表面）３１ｃから突出している。リブ３４は、半円筒部３１の周方向に沿って延びたリブ状に形成され、半円筒部３１の周方向の一端部３１ａと他端部３１ｂとの間の全長に亘って形成されている。リブ３４は、蛇腹筒部２５の谷部２５ｂ内に進入可能な幅かつ形状に形成されている。   The rib 34 protrudes from an inner surface (surface) 31 c that is overlapped with the bellows tube portion 25 of the semi-cylindrical portion 31. The rib 34 is formed in a rib shape extending along the circumferential direction of the semi-cylindrical portion 31, and is formed over the entire length between the one end portion 31 a and the other end portion 31 b in the circumferential direction of the semi-cylindrical portion 31. . The rib 34 is formed in a width and shape that can enter the valley portion 25 b of the bellows tube portion 25.

前述したリブ３４は、互いに平行に複数（図示例では３つ）設けられている。これらリブ３４は、半円筒部３１の長手方向に沿って互いに間隔をあけている。この間隔は、蛇腹筒部２５の互いに隣り合う谷部２５ｂ間の間隔の自然数倍とされている。このため、各リブ３４は、中立状態（弾性変形していない状態）かつ伸びた状態の蛇腹筒部２５の谷部２５ｂ内に進入可能である。リブ３４は、図３に示すように、半円筒部３１が前記状態の蛇腹筒部２５に重ねられると谷部２５ｂ内に位置付けられる。   A plurality of ribs 34 (three in the illustrated example) are provided in parallel to each other. These ribs 34 are spaced apart from each other along the longitudinal direction of the semi-cylindrical portion 31. This interval is a natural number multiple of the interval between the adjacent valley portions 25b of the bellows tube portion 25. For this reason, each rib 34 can enter the valley portion 25b of the bellows tube portion 25 in a neutral state (a state where it is not elastically deformed) and in an extended state. As shown in FIG. 3, the rib 34 is positioned in the valley portion 25 b when the semicylindrical portion 31 is overlapped with the bellows tube portion 25 in the above state.

ロック部３５は、図２に示すように、半円筒部３１の周方向の他端部３１ｂかつ半円筒部３１の長手方向中央に設けられている。ロック部３５は、箱状に形成され、半円筒部３１の外面３１ｄから突出している。ロック部３５には、ロック孔３５ａと、ロック突部３５ｂとが設けられている。   As shown in FIG. 2, the lock portion 35 is provided at the other end portion 31 b in the circumferential direction of the semicylindrical portion 31 and at the center in the longitudinal direction of the semicylindrical portion 31. The lock part 35 is formed in a box shape and protrudes from the outer surface 31 d of the semi-cylindrical part 31. The lock portion 35 is provided with a lock hole 35a and a lock protrusion 35b.

ロック孔３５ａは、平面形状が矩形状に形成され、図２中の上下方向に沿ってロック部３５を貫通している。ロック孔３５ａには、図２中上方から下方に向かって矢印Ｂに沿ってバンド部３２が挿入される。   The lock hole 35a has a rectangular planar shape and penetrates the lock portion 35 along the vertical direction in FIG. The band portion 32 is inserted into the lock hole 35a along the arrow B from the upper side to the lower side in FIG.

ロック突部３５ｂは、ロック孔３５ａの半円筒部３１寄りの内面から突出している。ロック突部３５ｂには、テーパ面と係止面とが設けられている。テーパ面は、ロック突部３５ｂの矢印Ｂ方向後方側に形成され、矢印Ｂ方向の反対方向にいくにしたがって徐々にロック孔３５ａの前記内面に近づく方向に傾斜している。係止面は、ロック突部３５ｂの矢印Ｂ方向前方側に形成され、矢印Ｂ方向に直交する方向に沿って平坦に形成されている。   The lock protrusion 35b protrudes from the inner surface of the lock hole 35a near the semi-cylindrical portion 31. The locking projection 35b is provided with a tapered surface and a locking surface. The taper surface is formed on the rear side in the arrow B direction of the lock protrusion 35b, and is gradually inclined toward the inner surface of the lock hole 35a as it goes in the opposite direction to the arrow B direction. The locking surface is formed on the front side of the lock projection 35b in the direction of arrow B, and is formed flat along a direction orthogonal to the direction of arrow B.

バンド部３２は、図２に示すように、半円筒部３１の長手方向に直交する方向に延びた帯板状に形成され、可撓自在に設けられている。バンド部３２は、長手方向の一端部３２ａが連結部３３に連なり、他端部（以下、先端部３２ｂという）が初期状態において一端部３２ａよりも半円筒部３１から離れた側に配されている。   As shown in FIG. 2, the band portion 32 is formed in a band plate shape extending in a direction orthogonal to the longitudinal direction of the semi-cylindrical portion 31 and is provided so as to be flexible. The band portion 32 has one end portion 32a in the longitudinal direction connected to the connecting portion 33, and the other end portion (hereinafter referred to as a tip portion 32b) is arranged on the side farther from the semi-cylindrical portion 31 than the one end portion 32a in the initial state. Yes.

また、図４に示すように、バンド部３２の幅Ｗ１（バンド部３２の半円筒部３１の長手方向に沿った長さ）は、半円筒部３１の長さＬよりも短く形成され、かつ谷部２５ｂの幅Ｘ（山部２５ａの頂部間の間隔）よりも狭く形成されている。このため、蛇腹筒部２５のプロテクタ３の取り付けられた部分は、半円筒部３１側には曲がらないが、バンド部３２側には曲がることができる（図４中、一点鎖線で示す）。   4, the width W1 of the band portion 32 (the length along the longitudinal direction of the semi-cylindrical portion 31 of the band portion 32) is formed shorter than the length L of the semi-cylindrical portion 31, and It is formed narrower than the width X of the valley portion 25b (interval between the top portions of the peak portions 25a). For this reason, the portion of the bellows tube portion 25 to which the protector 3 is attached does not bend toward the semi-cylindrical portion 31 side, but can be bent toward the band portion 32 side (indicated by a one-dot chain line in FIG. 4).

また、図２に示すように、バンド部３２の一方の表面３２ｃには、半円筒部３１のロック部３５と係合可能な係合受け部としてのロック突起３６が設けられている。ロック突起３６は、バンド部３２の長手方向に沿って並んで複数設けられ、鋸歯状に形成されている。ロック突起３６は、バンド部３２の先端部３２ｂを含めたバンド部３２の略全長に亘って設けられている。このため、バンド部３２は、長手方向の略任意の位置でロック部３５と係合可能であり、半円筒部３１との間に蛇腹筒部２５を縮径させた状態で挟むことができる。縮径とは、蛇腹筒部２５を径方向に弾性変形させて外径を小さくすることを意味する。   As shown in FIG. 2, a lock protrusion 36 as an engagement receiving portion that can be engaged with the lock portion 35 of the semi-cylindrical portion 31 is provided on one surface 32 c of the band portion 32. A plurality of lock protrusions 36 are provided side by side along the longitudinal direction of the band portion 32 and are formed in a sawtooth shape. The lock protrusion 36 is provided over substantially the entire length of the band portion 32 including the tip end portion 32 b of the band portion 32. For this reason, the band part 32 can be engaged with the lock part 35 at a substantially arbitrary position in the longitudinal direction, and can be sandwiched between the semi-cylindrical part 31 in a state where the diameter of the bellows cylinder part 25 is reduced. The reduced diameter means that the outer diameter is reduced by elastically deforming the bellows cylinder portion 25 in the radial direction.

また、ロック突起３６には、テーパ面と係止面とが設けられている。テーパ面は、ロック突起３６のバンド部３２の先端部３２ｂ側に形成され、バンド部３２の先端部３２ｂに近づくにしたがって徐々にバンド部３２の表面３２ｃに近づく方向に傾斜している。係止面は、ロック突起３６のバンド部３２の先端部３２ｂから離れた側に形成され、バンド部３２の表面３２ｃに直交する方向に沿って平坦に形成されている。   Further, the lock protrusion 36 is provided with a tapered surface and a locking surface. The taper surface is formed on the side of the tip 32b of the band 32 of the lock protrusion 36, and is gradually inclined toward the surface 32c of the band 32 as it approaches the tip 32b of the band 32. The locking surface is formed on the side of the locking protrusion 36 away from the tip 32b of the band 32, and is formed flat along a direction orthogonal to the surface 32c of the band 32.

前述したバンド部３２は、ロック突起３６の設けられた表面３２ｃが半円筒部３１の内面３１ｃと相対する方向に曲げられて、前記表面３２ｃが半円筒部３１内に位置付けられた蛇腹筒部２５の外周面に重ねられる。前記表面３２ｃは、前述したトランクパネル９２の回転中心Ｐと相対する側の蛇腹筒部２５の外周面に重ねられる。そして、バンド部３２は、先端部３２ｂのロック突起３６が半円筒部３１の長手方向中央に設けられたロック部３５と係合して、半円筒部３１の長手方向中央に、半円筒部３１の周方向に沿って取り付けられる。   In the band portion 32 described above, the bellows tube portion 25 in which the surface 32 c provided with the lock protrusion 36 is bent in a direction facing the inner surface 31 c of the semi-cylindrical portion 31, and the surface 32 c is positioned in the semi-cylindrical portion 31. It is overlaid on the outer peripheral surface. The surface 32c is overlaid on the outer peripheral surface of the bellows tube portion 25 on the side facing the rotation center P of the trunk panel 92 described above. The band portion 32 engages with the lock portion 35 provided at the center in the longitudinal direction of the semi-cylindrical portion 31 with the lock projection 36 of the tip end portion 32 b, and the semi-cylindrical portion 31 is located at the center in the longitudinal direction of the semi-cylindrical portion 31. It is attached along the circumferential direction.

連結部３３は、図２に示すように、矩形平板状に形成されている。連結部３３は、半円筒部３１の長手方向において、複数のリブ３４のうち中央に配されたリブ３４と同位置に設けられている。連結部３３は、一端が半円筒部３１の一端部３１ａかつ半円筒部３１の長手方向中央の外面３１ｄと連なり、他端がバンド部３２の長手方向の一端部３２ａに連なって、これら一端部３１ａ、３２ａ同士を互いに連結している。   As shown in FIG. 2, the connecting portion 33 is formed in a rectangular flat plate shape. The connecting portion 33 is provided at the same position as the rib 34 disposed in the center among the plurality of ribs 34 in the longitudinal direction of the semi-cylindrical portion 31. The connecting portion 33 has one end connected to one end 31 a of the semi-cylindrical portion 31 and the outer surface 31 d in the longitudinal center of the semi-cylindrical portion 31, and the other end connected to one end 32 a in the longitudinal direction of the band portion 32. 31a and 32a are mutually connected.

前述した構成のグロメット１Ａを組み立てる際には、前述のように車体パネル９１及びトランクパネル９２に嵌合したグロメット本体２において、蛇腹筒部２５の曲がりを規制したい部分（図示例では蛇腹筒部２５の中央部分）の外周面にプロテクタ３の半円筒部３１の内面３１ｃを重ねて、半円筒部３１のリブ３４を蛇腹筒部２５の谷部２５ｂ内に位置付ける。このとき、半円筒部３１の内面３１ｃが、トランクパネル９２の回転中心Ｐから離れた側の蛇腹筒部２５の外周面に重なるようにする。   When assembling the grommet 1A having the above-described configuration, in the grommet main body 2 fitted to the vehicle body panel 91 and the trunk panel 92 as described above, the portion of the grommet cylinder portion 25 where the bending of the bellows cylinder portion 25 is desired (in the illustrated example, the bellows cylinder portion 25). The inner surface 31c of the semi-cylindrical portion 31 of the protector 3 is overlapped with the outer peripheral surface of the protector 3 so that the rib 34 of the semi-cylindrical portion 31 is positioned in the valley portion 25b of the bellows cylinder portion 25. At this time, the inner surface 31 c of the semi-cylindrical portion 31 is made to overlap the outer peripheral surface of the bellows tube portion 25 on the side away from the rotation center P of the trunk panel 92.

次いで、バンド部３２の表面３２ｃが前記回転中心Ｐと相対する側の蛇腹筒部２５の外周面に重なるようにバンド部３２を曲げ、バンド部３２を先端部３２ｂ側から半円筒部３１のロック部３５のロック孔３５ａ内に挿入していく。すると、まず、バンド部３２の最先端に位置するロック突起３６のテーパ面がロック孔３５ａ内に突出したロック突部３５ｂのテーパ面を乗り超えて、前記ロック突起３６がロック突部３５ｂと係合する。   Next, the band portion 32 is bent so that the surface 32c of the band portion 32 overlaps the outer peripheral surface of the bellows cylinder portion 25 on the side facing the rotation center P, and the band portion 32 is locked from the tip end portion 32b side to the semi-cylindrical portion 31. It is inserted into the lock hole 35a of the portion 35. Then, first, the taper surface of the lock projection 36 located at the forefront of the band portion 32 gets over the taper surface of the lock projection 35b protruding into the lock hole 35a, and the lock projection 36 is engaged with the lock projection 35b. Match.

さらにバンド部３２を押し込んでいくと、前記ロック突起３６よりもバンド部３２の先端部３２ｂから離れた側のロック突起３６のテーパ面が順次ロック突部３５ｂのテーパ面を乗り越えて、バンド部３２の先端部３２ｂがロック孔３５ａを通り抜け、バンド部３２が蛇腹筒部２５に徐々に近づいていく。   When the band portion 32 is further pushed in, the taper surface of the lock protrusion 36 on the side farther from the tip end portion 32b of the band portion 32 than the lock protrusion 36 sequentially passes over the taper surface of the lock protrusion 35b. The front end portion 32b passes through the lock hole 35a, and the band portion 32 gradually approaches the bellows tube portion 25.

その後、ロック孔３５ａを通り抜けたバンド部３２の先端部３２ｂを引っ張ってバンド部３２をさらに蛇腹筒部２５に近づけると、バンド部３２が谷部２５ｂ内に押し込まれてバンド部３２と半円筒部３１の間で蛇腹筒部２５が締め付けられて縮径する。そして、バンド部３２のロック突起３６とロック部３５とが互いに係合し、ロック突起３６の係止面とロック突部３５ｂの係止面とが互いに係止して、バンド部３２がロック孔３５ａ内に保持される。こうして、バンド部３２と半円筒部３１との間に縮径された蛇腹筒部２５を挟んだ状態で、プロテクタ３が蛇腹筒部２５の外周に取り付けられる。   Thereafter, when the band portion 32 is further brought closer to the bellows cylinder portion 25 by pulling the tip end portion 32b of the band portion 32 that has passed through the lock hole 35a, the band portion 32 is pushed into the valley portion 25b, and the band portion 32 and the semi-cylindrical portion. The bellows tube portion 25 is tightened between 31 to reduce the diameter. Then, the locking projection 36 and the locking portion 35 of the band portion 32 are engaged with each other, the locking surface of the locking projection 36 and the locking surface of the locking projection 35b are locked with each other, and the band portion 32 has the locking hole. 35a. Thus, the protector 3 is attached to the outer periphery of the bellows cylinder portion 25 with the bellows cylinder portion 25 having a reduced diameter interposed between the band portion 32 and the semicylindrical portion 31.

このように組み立てられたグロメット１Ａにおいて、トランクパネル９２が矢印Ｐ１方向に回転して車体パネル９１に近づく（トランクが閉じる）と、図５（ａ）に模式的に示すように、蛇腹筒部２５がＵ字状に曲がる。このとき、蛇腹筒部２５のプロテクタ３の取り付けられた部分は、バンド部３２に締め付けられた中央部分が半円筒部３１から離れず、両端部分が半円筒部３１から離れる方向に変位する。そして、蛇腹筒部２５は、前記中央部分で折れるようにコンパクトな（幅狭な）Ｕ字状に曲がり、車体パネル９１に取り付けられた周辺部品９４、車体パネル９１やトランクパネル９２等に接触しなくなる。   In the grommet 1A assembled in this way, when the trunk panel 92 rotates in the direction of the arrow P1 and approaches the vehicle body panel 91 (the trunk is closed), as shown schematically in FIG. Bends in a U-shape. At this time, the portion of the bellows tube portion 25 to which the protector 3 is attached is displaced in a direction in which the central portion fastened to the band portion 32 is not separated from the semi-cylindrical portion 31 and both end portions are separated from the semi-cylindrical portion 31. The bellows tube portion 25 bends into a compact (narrow) U shape so that it can be folded at the central portion, and comes into contact with peripheral components 94 attached to the vehicle body panel 91, the vehicle body panel 91, the trunk panel 92, and the like. Disappear.

この状態から、トランクパネル９２が矢印Ｐ１方向に回転して車体パネル９１から離れる（トランクが開く）と、図５（ｂ）に模式的に示すように、蛇腹筒部２５のプロテクタ３の取り付けられた部分は、バンド部３２に締め付けられた中央部分が半円筒部３１から離れずに、両端部分が半円筒部３１に近づくように変位する（必ずしも蛇腹筒部２５がプロテクタ３と重ならない）。そして、蛇腹筒部２５は、全体としてＣ字状に曲がる。   From this state, when the trunk panel 92 rotates in the direction of the arrow P1 and moves away from the vehicle body panel 91 (the trunk opens), the protector 3 of the bellows cylinder portion 25 is attached as schematically shown in FIG. The center part fastened to the band part 32 is displaced from the semi-cylindrical part 31 without the central part being separated from the semi-cylindrical part 31 (the bellows cylinder part 25 does not necessarily overlap with the protector 3). And the bellows cylinder part 25 bends in C shape as a whole.

本実施形態によれば、バンド部３２の幅Ｗ１が半円筒部３１の長さＬよりも短く形成され、半円筒部３１との間に蛇腹筒部２５を縮径された状態で挟む。このため、トランクパネル９２が回転して車体パネル９１に近づいたときに、蛇腹筒部２５をよりコンパクトな略Ｕ字状に曲げることができる。したがって、蛇腹筒部２５が車体パネル９１に取り付けられた周辺部品９４等に接触して破損することを防止できる。   According to this embodiment, the width W <b> 1 of the band portion 32 is formed to be shorter than the length L of the semi-cylindrical portion 31, and the bellows tube portion 25 is sandwiched between the semi-cylindrical portion 31 in a reduced diameter state. For this reason, when the trunk panel 92 rotates and approaches the vehicle body panel 91, the bellows tube portion 25 can be bent into a more compact substantially U-shape. Accordingly, it is possible to prevent the bellows tube portion 25 from being damaged by coming into contact with the peripheral component 94 attached to the vehicle body panel 91 or the like.

さらに、蛇腹筒部２５にプロテクタ３を取り付けるだけでよいので、汎用性を向上させることができる。また、半円筒部３１が周辺部品９４等により近い蛇腹筒部２５の外周面に配されるので、蛇腹筒部２５のプロテクタ３の取り付けられた部分近傍が周辺部品９４等に接触した場合であっても、蛇腹筒部２５が直接周辺部品９４等に接触することを防止できる。また、半円筒部３１やバンド部３２の長さをそれぞれ変更することによって、周辺部品９４等のレイアウトに合わせて蛇腹筒部２５の曲がる方向（形状）を自由に変更することができる。   Furthermore, since only the protector 3 needs to be attached to the bellows tube portion 25, versatility can be improved. Further, since the semi-cylindrical portion 31 is arranged on the outer peripheral surface of the bellows cylinder portion 25 closer to the peripheral component 94 and the like, the vicinity of the portion where the protector 3 of the bellows cylinder portion 25 is attached contacts the peripheral component 94 and the like. However, the bellows tube portion 25 can be prevented from directly contacting the peripheral component 94 or the like. Further, by changing the lengths of the semi-cylindrical part 31 and the band part 32, the bending direction (shape) of the bellows cylinder part 25 can be freely changed according to the layout of the peripheral components 94 and the like.

また、連結部３３が半円筒部３１とバンド部３２を互いに連結しており、半円筒部３１のロック部３５とバンド部３２のロック突起３６とが互いに係合してプロテクタ３が組み立てられる。したがって、プロテクタ３が１部品になって部品数を削減でき、取扱性を向上させることができるとともに、半円筒部３１とバンド部３２を簡単かつ確実に取り付けることができる。   Further, the connecting portion 33 connects the semi-cylindrical portion 31 and the band portion 32 to each other, and the lock portion 35 of the semi-cylindrical portion 31 and the lock protrusion 36 of the band portion 32 are engaged with each other to assemble the protector 3. Therefore, the protector 3 becomes one part, the number of parts can be reduced, the handleability can be improved, and the semi-cylindrical part 31 and the band part 32 can be easily and reliably attached.

また、バンド部３２の幅Ｗ１が、蛇腹筒部２５の谷部２５ｂの幅Ｘよりも短く形成されているので、バンド部３２が谷部２５ｂ内に位置付けられる。したがって、プロテクタ３を蛇腹筒部２５の長手方向の所望の位置に位置ずれすることなく取り付けることができ、またこれによって周辺部品９４等のレイアウトに合わせて蛇腹筒部２５の曲がる位置（曲がらない位置）を自由に変更することができる。   Moreover, since the width W1 of the band part 32 is formed shorter than the width X of the valley part 25b of the bellows cylinder part 25, the band part 32 is positioned within the valley part 25b. Therefore, the protector 3 can be attached to the desired position in the longitudinal direction of the bellows tube portion 25 without being displaced, and thereby the position at which the bellows tube portion 25 bends according to the layout of the peripheral component 94 or the like (the position where it does not bend). ) Can be changed freely.

また、バンド部３２が半円筒部３１の長手方向中央に取り付けられている。このため、蛇腹筒部２５のプロテクタ３の取り付けられた部分は、その両端が半円筒部３１から離れてバンド部３２側に近づく方向に変位して、略Ｕ字状に曲がる。したがって、蛇腹筒部２５をさらに確実にコンパクトに曲げることができる。   A band portion 32 is attached to the center of the semi-cylindrical portion 31 in the longitudinal direction. For this reason, the part to which the protector 3 of the bellows cylinder part 25 is attached is displaced in a direction in which both ends thereof are separated from the semi-cylindrical part 31 and approach the band part 32 side, and bends in a substantially U shape. Therefore, the bellows tube portion 25 can be bent more reliably and compactly.

また、リブ３４が半円筒部３１の内面３１ｃから突出して設けられ、蛇腹筒部２５の谷部２５ｂ内に位置付けられる。したがって、プロテクタ３を蛇腹筒部２５の長手方向の所望の位置に位置ずれすることなく取り付けることができ、周辺部品９４等のレイアウトに合わせて蛇腹筒部２５の曲がる位置（曲がらない位置）を自由に変更することができる。   Further, the rib 34 is provided so as to protrude from the inner surface 31 c of the semi-cylindrical portion 31 and is positioned in the valley portion 25 b of the bellows tube portion 25. Therefore, the protector 3 can be attached to the desired position in the longitudinal direction of the bellows cylinder portion 25 without being displaced, and the position at which the bellows cylinder portion 25 bends (the position at which it does not bend) can be freely adjusted according to the layout of the peripheral components 94 and the like. Can be changed.

前述した実施形態においては、連結部３３が半円筒部３１とバンド部３２と互いに連結していたが、連結部３３を設けずに半円筒部３１とバンド部３２とを直接連結してもよいし、半円筒部３１とバンド部３２の一端部３１ａ、３２ａにそれぞれ互いに係合する係合部及び係合受け部を設けて半円筒部３１とバンド部３２とを別体で形成してもよい。   In the embodiment described above, the connecting portion 33 is connected to the semi-cylindrical portion 31 and the band portion 32. However, the semi-cylindrical portion 31 and the band portion 32 may be directly connected without providing the connecting portion 33. Alternatively, the semi-cylindrical portion 31 and the band portion 32 may be formed separately by providing the semi-cylindrical portion 31 and the band portion 32 separately by providing an engaging portion and an engaging receiving portion that engage with each other at one end portions 31a and 32a of the band portion 32, respectively. Good.

また、前述した実施形態においては、リブ３４が設けられていたが、バンド部３２が蛇腹筒部２５を縮径させるように半円筒部３１に取り付けられ、またバンド部３２が蛇腹筒部２５の谷部２５ｂ内に位置付けられるので、必ずしもリブ３４を設けなくてもよい。また、リブ３４のかわりに、柱状の突部を設けてもよい。この場合、柱状の突部は、１つでもよいが、半円筒部３１の周方向に沿って並んで複数設けるとリブ３４と略同様に機能するので好ましい。   In the above-described embodiment, the rib 34 is provided. However, the band portion 32 is attached to the semi-cylindrical portion 31 so as to reduce the diameter of the bellows tube portion 25, and the band portion 32 is attached to the bellows tube portion 25. The rib 34 is not necessarily provided because it is positioned in the valley 25b. Further, instead of the ribs 34, columnar protrusions may be provided. In this case, the number of columnar protrusions may be one, but it is preferable to provide a plurality of columnar protrusions side by side along the circumferential direction of the semi-cylindrical portion 31 because it functions substantially the same as the ribs 34.

また、前述した実施形態においては、プロテクタ３はグロメット本体２よりも硬質な材料で構成されていたが、必ずしも前記硬質な材料で構成されていなくてもよい。また、前述した実施形態においては、一方のパネルが車体パネル９１とされ、他方のパネルがトランクパネル９２とされていたが、各パネルはこれら以外でもよく、例えば他方のパネルはドアパネルであってもよい。   In the above-described embodiment, the protector 3 is made of a material harder than the grommet body 2, but the protector 3 is not necessarily made of the hard material. In the above-described embodiment, one panel is the vehicle body panel 91 and the other panel is the trunk panel 92. However, each panel may be other than these, for example, the other panel may be a door panel. Good.

また、前述した実施形態においては、バンド部３２の幅Ｗ１は谷部２５ｂの幅Ｘよりも幅狭に形成されていたが、バンド部３２を図６に示すように谷部２５ｂの幅Ｘよりも幅広なバンド部３２Ａとしてもよい。この場合、バンド部３２Ａは、谷部２５ｂ内に位置付けられずに複数の谷部２５ｂを覆うように配されるので、蛇腹筒部２５に対するプロテクタ３の位置ずれを防止できないが、半円筒部３１にリブ３４が設けられているので問題はない。   In the embodiment described above, the width W1 of the band portion 32 is formed narrower than the width X of the valley portion 25b. However, the band portion 32 is smaller than the width X of the valley portion 25b as shown in FIG. Alternatively, the wide band portion 32A may be used. In this case, since the band portion 32A is arranged so as to cover the plurality of valley portions 25b without being positioned in the valley portion 25b, the position shift of the protector 3 with respect to the bellows cylinder portion 25 cannot be prevented, but the semi-cylindrical portion 31 There is no problem because the ribs 34 are provided.

次に、本発明の第２の実施形態にかかるグロメット１Ｂを、図７及び図８を参照して説明する。なお、前述した第１の実施形態と同一構成部分には、同一符号を付して説明を省略する。   Next, a grommet 1B according to a second embodiment of the present invention will be described with reference to FIGS. Note that the same components as those in the first embodiment described above are denoted by the same reference numerals and description thereof is omitted.

本発明の第２の実施形態にかかるグロメット１Ｂは、前述した第１の実施形態のプロテクタ３と異なる形状のプロテクタ４を備えている。プロテクタ４は、図７に示すように、一方の取付部としての半円筒部３１と、他方の取付部としての第２半円筒部４２と、半円筒部３１の一端部３１ａと第２半円筒部４２の周方向の一端部４２ａとを互いに連結する連結部４３とを一体に備えている。半円筒部３１には、係合部としてのロック部４５が設けられている。   A grommet 1B according to the second embodiment of the present invention includes a protector 4 having a shape different from that of the protector 3 according to the first embodiment described above. As shown in FIG. 7, the protector 4 includes a semi-cylindrical portion 31 as one attachment portion, a second semi-cylindrical portion 42 as the other attachment portion, an end portion 31a of the semi-cylindrical portion 31, and a second semi-cylindrical portion. The connection part 43 which mutually connects the edge part 42a of the circumferential direction of the part 42 is integrally provided. The semi-cylindrical portion 31 is provided with a lock portion 45 as an engaging portion.

ロック部４５は、半円筒部３１の他端部３１ｂの外壁３１ｅと、この外壁３１ｅから立設しかつ互いに平行な一対の立設壁４５ａと、これら立設壁４５ａを互いに連結した連結壁４５ｂとから構成され、角筒状に形成されている。前記半円筒部３１の外壁３１ｅには、半円筒部３１の端面から直線状に当該外壁３１ｅを切り欠いた切り欠き部４５ｃが形成されている。また、連結壁４５ｂには、当該連結壁４５ｂの中央を貫通しかつ平面形状が矩形状のロック孔４５ｄが設けられている。ロック部４５は、図７中の上下方向に沿って開口している。ロック部４５内には、図７中の上方から下方に向かって矢印Ｂに沿って第２半円筒部４２の後述するロック爪４８が挿入される。   The lock portion 45 includes an outer wall 31e of the other end portion 31b of the semi-cylindrical portion 31, a pair of standing walls 45a that are erected from the outer wall 31e and parallel to each other, and a connecting wall 45b that connects the erected walls 45a to each other. And is formed in a rectangular tube shape. The outer wall 31e of the semi-cylindrical portion 31 is formed with a notch portion 45c in which the outer wall 31e is notched linearly from the end surface of the semi-cylindrical portion 31. Further, the connection wall 45b is provided with a lock hole 45d penetrating the center of the connection wall 45b and having a rectangular planar shape. The lock part 45 is opened along the up-down direction in FIG. A lock claw 48 described later of the second semi-cylindrical portion 42 is inserted into the lock portion 45 along the arrow B from the upper side to the lower side in FIG.

第２半円筒部４２は、短い半円筒状（短樋状）に形成され、半円筒部３１と略同一曲率で湾曲している。第２半円筒部４２は、周方向の一端部４２ａが連結部４３に連なり、他端部４２ｂが初期状態において一端部４２ａよりも半円筒部３１から離れた側に配されている。   The second semi-cylindrical portion 42 is formed in a short semi-cylindrical shape (short rod shape), and is curved with substantially the same curvature as the semi-cylindrical portion 31. In the second semi-cylindrical portion 42, one end portion 42a in the circumferential direction is connected to the connecting portion 43, and the other end portion 42b is arranged on the side farther from the semi-cylindrical portion 31 than the one end portion 42a in the initial state.

また、図７に示すように、第２半円筒部４２の幅Ｗ２（第２半円筒部４２の半円筒部３１の長手方向に沿った長さ）は、半円筒部３１の長さＬよりも短く形成され、かつ複数の谷部２５ｂを覆うことができる幅に形成されている。このため、蛇腹筒部２５のプロテクタ４の取り付けられた部分は、半円筒部３１側には曲がらないが、第２半円筒部４２側には曲がることができる（図８中、一点鎖線で示す）。第２半円筒部４２には、図７に示すように、突部としてのリブ４４と、係合受け部としてのロック爪４８とが設けられている。   As shown in FIG. 7, the width W <b> 2 of the second semicylindrical portion 42 (the length along the longitudinal direction of the semicylindrical portion 31 of the second semicylindrical portion 42) is greater than the length L of the semicylindrical portion 31. Are formed so as to have a width that can cover the plurality of valley portions 25b. For this reason, the portion of the bellows tube portion 25 to which the protector 4 is attached does not bend toward the semi-cylindrical portion 31 side, but can be bent toward the second semi-cylindrical portion 42 side (indicated by a one-dot chain line in FIG. 8). ). As shown in FIG. 7, the second semi-cylindrical portion 42 is provided with a rib 44 as a projecting portion and a lock claw 48 as an engagement receiving portion.

リブ４４は、第２半円筒部４２の蛇腹筒部２５に重ねられる内面（表面）４２ｃから突出している。リブ４４は、半円筒部３１のリブ３４と同一形状に形成されている。リブ４４は、第２半円筒部４２の中心軸方向中央に１つ設けられ、半円筒部３１の複数のリブ３４のうち中央に配されたリブ３４と同位置に設けられている。   The rib 44 protrudes from an inner surface (surface) 42c that is overlaid on the bellows tube portion 25 of the second semi-cylindrical portion 42. The rib 44 is formed in the same shape as the rib 34 of the semi-cylindrical portion 31. One rib 44 is provided at the center in the central axis direction of the second semi-cylindrical portion 42, and is provided at the same position as the rib 34 disposed at the center among the plurality of ribs 34 of the semi-cylindrical portion 31.

ロック爪４８は、第２半円筒部４２の周方向の他端部４２ｂから当該第２半円筒部４２の周方向に沿って突出している。ロック爪４８には、突状部４８ａ（図７）と、ロック突起４８ｂ（図８）とが設けられている。突状部４８ａは、ロック爪４８の第２半円筒部４２の内面４２ｃ側の一方の表面から突出し、前記一方の表面の中央にロック爪４８の突出する方向に沿って延びたリブ状に形成されている。   The lock claw 48 protrudes from the other end portion 42 b in the circumferential direction of the second semi-cylindrical portion 42 along the circumferential direction of the second semi-cylindrical portion 42. The lock claw 48 is provided with a protrusion 48a (FIG. 7) and a lock protrusion 48b (FIG. 8). The protrusion 48a protrudes from one surface on the inner surface 42c side of the second semi-cylindrical portion 42 of the lock claw 48, and is formed in a rib shape extending along the direction in which the lock claw 48 protrudes at the center of the one surface. Has been.

ロック突起４８ｂは、ロック爪４８の第２半円筒部４２の外面側の他方の表面から突出している。ロック突起４８ｂには、テーパ面と係止面とが設けられている。テーパ面は、ロック突起４８ｂのロック爪４８先端側に形成され、ロック爪４８先端に近づくにしたがって徐々に前記他方の表面に近づく方向に傾斜している。係止面は、ロック突起４８ｂのロック爪４８基端側に形成され、前記他方の表面に直交する方向に沿って平坦に形成されている。   The lock protrusion 48 b protrudes from the other surface on the outer surface side of the second semi-cylindrical portion 42 of the lock claw 48. The lock protrusion 48b is provided with a tapered surface and a locking surface. The tapered surface is formed on the front end side of the lock claw 48 of the lock projection 48b, and is gradually inclined toward the other surface as it approaches the front end of the lock claw 48. The locking surface is formed on the base end side of the lock claw 48 of the lock protrusion 48b, and is formed flat along a direction orthogonal to the other surface.

前述したロック爪４８のロック突起４８ｂがロック部４５のロック孔４５ｄ内に位置付けられてロック爪４８とロック部４５とが互いに係合すると、第２半円筒部４２が半円筒部３１に取り付けられて筒状になる。ロック突起４８ｂとロック孔４５ｄとは、前記筒状の部分の内径が少なくとも蛇腹筒部２５の最大外径よりも小さくなるような位置にそれぞれ設けられている。このため、蛇腹筒部２５の前記筒状の部分に位置付けられた部分は、ロック爪４８とロック部４５とが互いに係合すると縮径される。   When the lock protrusion 48b of the lock claw 48 described above is positioned in the lock hole 45d of the lock portion 45 and the lock claw 48 and the lock portion 45 engage with each other, the second semi-cylindrical portion 42 is attached to the semi-cylindrical portion 31. Become cylindrical. The lock protrusion 48b and the lock hole 45d are provided at positions where the inner diameter of the cylindrical portion is at least smaller than the maximum outer diameter of the bellows cylinder portion 25, respectively. For this reason, when the lock claw 48 and the lock part 45 engage with each other, the diameter of the part positioned at the cylindrical part of the bellows cylinder part 25 is reduced.

連結部４３は、長尺薄板状の板ヒンジ状に形成され、可撓自在に設けられている。連結部４３は、一端が半円筒部３１の一端部３１ａかつ半円筒部３１の長手方向中央の外面３１ｄと連なり、他端が第２半円筒部４２の周方向の一端部４２ａの外面に連なって、これら一端部３１ａ、４２ａ同士を互いに連結している。   The connecting portion 43 is formed in a long thin plate-like plate hinge shape and is provided so as to be flexible. One end of the connecting portion 43 is connected to one end portion 31 a of the semi-cylindrical portion 31 and the outer surface 31 d in the longitudinal center of the semi-cylindrical portion 31, and the other end is connected to the outer surface of the one end portion 42 a in the circumferential direction of the second semi-cylindrical portion 42. The one end portions 31a and 42a are connected to each other.

前述したプロテクタ４をグロメット本体２に取り付ける際には、トランクパネル９２の回転中心Ｐから離れた側の蛇腹筒部２５の外周面に半円筒部３１の内面３１ｃを重ねる。その後、第２半円筒部４２の内面４２ｃが前記回転中心Ｐと相対する側の外周面に重なるように第２半円筒部４２を蛇腹筒部２５に近づけていき、ロック爪４８をロック部４５内に挿入していく。すると、ロック部４５の連結壁４５ｂがロック爪４８のロック突起４８ｂと当接した後にロック突起４８ｂのテーパ面上に乗り上げて、連結壁４５ｂと半円筒部３１の外壁３１ｅの間の間隔が押し広げられる。   When the protector 4 described above is attached to the grommet body 2, the inner surface 31 c of the semi-cylindrical portion 31 is overlapped with the outer peripheral surface of the bellows tube portion 25 on the side away from the rotation center P of the trunk panel 92. Thereafter, the second semi-cylindrical portion 42 is brought close to the bellows tube portion 25 so that the inner surface 42c of the second semi-cylindrical portion 42 overlaps the outer peripheral surface on the side facing the rotation center P, and the lock pawl 48 is moved to the lock portion 45. Insert it inside. Then, after the connecting wall 45b of the lock portion 45 comes into contact with the lock projection 48b of the lock claw 48, it rides on the taper surface of the lock projection 48b, and the interval between the connection wall 45b and the outer wall 31e of the semi-cylindrical portion 31 is pushed. Can be spread.

そして、さらに第２半円筒部４２を蛇腹筒部２５に近づけてロック爪４８をロック部４５内に挿入していくと、突状部４８ａが切り欠き部４５ｃ内に進入するとともに、第２半円筒部４２と半円筒部３１の間で蛇腹筒部２５が締め付けられて当該蛇腹筒部２５が縮径していく。   When the second semi-cylindrical portion 42 is further moved closer to the bellows tube portion 25 and the lock claw 48 is inserted into the lock portion 45, the projecting portion 48a enters the cutout portion 45c, and the second half-cylindrical portion 42 enters. The bellows tube portion 25 is tightened between the cylindrical portion 42 and the semi-cylindrical portion 31 and the bellows tube portion 25 is reduced in diameter.

その後、ロック突起４８ｂがロック部４５のロック孔４５ｄ内に位置付けられると、連結壁４５ｂと半円筒部３１の外壁３１ｅ間の間隔が中立状態に復帰してロック爪４８とロック部４５とが互いに係合し、ロック突起４８ｂの係止面とロック孔４５ｄの内面とが互いに係止して、ロック爪４８がロック部４５内に保持される。こうして、第２半円筒部４２と半円筒部３１との間に縮径された蛇腹筒部２５を挟んだ状態で、プロテクタ４が蛇腹筒部２５の外周に取り付けられる。   Thereafter, when the lock protrusion 48b is positioned in the lock hole 45d of the lock portion 45, the interval between the connecting wall 45b and the outer wall 31e of the semi-cylindrical portion 31 returns to the neutral state, and the lock claw 48 and the lock portion 45 are mutually connected. The engaging surface of the lock protrusion 48 b and the inner surface of the lock hole 45 d are engaged with each other, and the lock claw 48 is held in the lock portion 45. Thus, the protector 4 is attached to the outer periphery of the bellows cylinder portion 25 with the bellows cylinder portion 25 having a reduced diameter interposed between the second semicylindrical portion 42 and the semicylindrical portion 31.

本実施形態においても、トランクパネル９２が回転して車体パネル９１に近づいたときに、蛇腹筒部２５をよりコンパクトな（幅狭な）略Ｕ字状に曲げることができ、蛇腹筒部２５が周辺部品等に接触して破損することを防止できる。   Also in this embodiment, when the trunk panel 92 rotates and approaches the vehicle body panel 91, the bellows tube portion 25 can be bent into a more compact (narrow) substantially U-shape. It is possible to prevent damage due to contact with peripheral parts.

また、本実施形態においては、半円筒部３１と第２半円筒部４２の内面３１ｃ、４２ｃにそれぞれリブ３４、４４が設けられている。したがって、プロテクタ４を蛇腹筒部２５の長手方向の所望の位置に位置ずれすることなく取り付けることができ、周辺部品等のレイアウトに合わせて蛇腹筒部２５の曲がる位置（曲がらない位置）を自由に変更することができる。   In the present embodiment, ribs 34 and 44 are provided on the inner surfaces 31c and 42c of the semi-cylindrical portion 31 and the second semi-cylindrical portion 42, respectively. Therefore, the protector 4 can be attached to the desired position in the longitudinal direction of the bellows cylinder portion 25 without being displaced, and the position at which the bellows cylinder portion 25 bends (the position at which it does not bend) can be freely adjusted in accordance with the layout of peripheral components and the like. Can be changed.

なお、前述した実施形態は本発明の代表的な形態を示したに過ぎず、本発明は、前述した実施形態に限定されるものではない。即ち、本発明の骨子を逸脱しない範囲で種々変形して実施することができる。   The above-described embodiments are merely representative examples of the present invention, and the present invention is not limited to the above-described embodiments.
