Description

【０００１】
【発明の属する技術分野】
この発明は、例えば車両等に装備され、不使用時にコイルばね体のばね力によってグリップ本体を使用位置から格納位置に回動させて格納するようにした格納式アシストグリップに関し、特に、コイルばね体の組付け対策に関するものである。
【０００２】
【従来の技術】
従来より、上述の如き格納式アシストグリップとして、長尺状のグリップ本体における長さ方向両端の一対の脚部をそれぞれ取付座を介して車体等に対し回動可能に軸支するとともに、少なくとも一方の脚部と取付座との間にコイルばね体を装着して、不使用時にコイルばね体のばね力によってグリップ本体を使用位置から格納位置に回動させて格納するようにした格納式アシストグリップが知られている（例えば、特許文献１参照）。
【０００３】
上記の特許文献１では、グリップ本体の一方の脚部には、グリップ本体が格納位置にあるときに車体パネルに対向する面に開口して取付座の一部を収容する取付座収容部が形成されている。また、上記一方の脚部を取付座に対して軸支する支持軸の周りにはコイルばね体が配置されていて、このコイルばね体の長さ方向一端部の外周から延長された線材の端部が上記一方の脚部に、また、同様にコイルばね体の他端部の外周から延長された線材の端部が取付座にそれぞれ係止されている。
【０００４】
【特許文献１】
特開平１０−２４７５９号公報（第４頁、図１２）
【０００５】
【発明が解決しようとする課題】
しかし、一般には、コイルばね体を脚部と取付座との間に装着する際、コイルばね体をコイルばね収納部内に収納した取付座を脚部の取付座収容部内に収容し、コイルばね体の一端側線材延長部を取付座収容部の開口辺部に形成された挿入溝に挿入してその底部に接触させるとともに、他端側線材延長部をコイルばね体収納部に接触させ、この状態で脚部、取付座及びコイルばね体に対して支持軸を挿通するようにしているため、取付座を取付座収容部内に配置してから支持軸を挿入するまでの間に取付座が動くと、コイルばね体の上記一端側線材延長部が挿入溝から外れて取付座収容部内に落ち込み、コイルばね体を脚部に組み付けるることができなくなる。
【０００６】
この発明はかかる点に鑑みてなされたものであり、その目的とするところは、取付座が取付座収容部内で動いても、コイルばね体の一端側線材延長部が取付座収容部内に落ち込まないようにしてコイルばね体を脚部に確実に組み付けるようにすることである。
【０００７】
【課題を解決するための手段】
上記の目的を達成するため、この発明は、コイルばね体の一端側線材延長部が挿入される挿入溝周りの構造に工夫を凝らしたことを特徴とする。
【０００８】
具体的には、この発明は、長さ方向の両端に脚部を有する長尺状のグリップ本体と、上記脚部をそれぞれ回動自在に軸支するとともに固定体に固定される一対の取付座と、上記グリップ本体の少なくとも一方の脚部と取付座との間に設けられ、グリップ本体を使用位置から格納位置に回動させるコイルばね体とを備えた格納式アシストグリップを対象とし、次のような解決手段を講じた。
【０００９】
すなわち、この発明は、上記グリップ本体の一方の脚部には、該グリップ本体が格納位置にあるときに上記固定体に対向する面に開口して取付座の一部を収容する取付座収容部が形成され、上記一方の脚部に対応する取付座には、上記取付座収容部に収容されてグリップ本体の長さ方向に延びる筒状のコイルばね体収納部が一体に形成され、上記コイルばね体は、その長さ方向両端部の外周から線材が平面視にてコイルばね体の長さ方向に略直交しかつ互いに略反対方向に延びる一対の第１延長部及び第２延長部を有し、上記取付座収容部は、少なくとも上記コイルばね体の長さ方向に略平行な開口辺部を有し、該開口辺部の長さ方向一端部には上記コイルばね体の第１延長部を上記取付座収容部の開口側から挿入する挿入溝が形成され、上記開口辺部の取付座収容部側には上記挿入溝の底部から取付座収容部内に向けて突出し上記挿入溝の底部と共に上記コイルばね体の第１延長部が圧接される座部が立設され、上記コイルばね体の第２延長部は、上記コイルばね体収納部に圧接されていることを特徴とする。
【００１０】
上記の構成により、この発明では、コイルばね体を収容した取付座を脚部の取付座収容部内に収容し、コイルばね体の第１延長部を取付座収容部の開口辺部に形成された挿入溝に挿入してその底部に接触させるとともに、第２延長部をコイルばね体収納部に接触させた状態で取付座が開口辺部から遠ざかるように取付座収容部内を動いても、上記第１延長部は挿入溝の底部から取付座収容部内に向けて突出する座部で受けられて取付座収容部内に落ち込まず、コイルばね体が脚部に確実に組み付けられる。
【００１１】
【発明の実施の形態】
以下、この発明の実施の形態について図面に基づいて説明する。
【００１２】
図７はこの発明の実施の形態に係る格納式アシストグリップＧを示し、このアシストグリップＧは、例えば車両の車室側壁に車室内に臨むように取付け固定される。
【００１３】
上記アシストグリップＧは、図７に示すように、例えばＰＰ（ポリプロピレン）等からなる樹脂製のグリップ本体１と、例えばＰＯＭ（ポリアセタール）等からなる一対の第１及び第２取付座３，５とを備えている。上記グリップ本体１は長尺バー状のもので、その長さ方向が車体前後方向と略一致するように配置されている。このグリップ本体１は長さ方向両端が同じ方向に湾曲して略コ字状をなし、当該部分がそれぞれ第１及び第２脚部１ａ，１ｂとされている。
【００１４】
上記第１及び第２取付座３，５は、第２取付座５を例に挙げて説明すると、図５に示すように、車室側壁の一部を構成する固定体としての車体パネルＰに表面側（車室側）から取付け固定されている。これら第１及び第２取付座３，５の取付位置に対応する車体パネルＰにはボルト挿通孔ｐ１が貫通形成され、車体パネルＰの裏面には上記ボルト挿通孔ｐ１に対応してウェルドナットＮが溶着されている。
【００１５】
上記グリップ本体１は、その一対の第１及び第２脚部１ａ，１ｂにてそれぞれ第１及び第２取付座３，５に回動可能に軸支されており、このような両脚部１ａ，１ｂによる軸支構造により、グリップ本体１は使用位置と格納位置との間で回動し、使用位置にあるときには、図７に示すように、グリップ本体１の中間部が車室内方に突出して水平面からやや斜め下方に向いた状態となる一方、格納位置にあるときには、図５に示すように、グリップ本体１が上記使用位置から略９０°上向きに回動して車室側壁の車体パネルＰに沿った状態となる。
【００１６】
上記グリップ本体１の第１及び第２脚部１ａ，１ｂにおいて、グリップ本体１が格納位置にあるときの車体パネルＰ対向面には、断面略矩形状に切り欠かれた平面視略半楕円形状の凹部からなる取付座収容部７が形成され、グリップ本体１の格納位置で各取付座収容部７内に上記第１及び第２取付座３，５の後述する取付座本体９の一部の車室側部を収容するようになっている。
【００１７】
上記第１及び第２取付座３，５は一部分を除いてその大半が同じ構造であり、まず、同じ構造部分について説明すると、図５及び図７に示すように、第１及び第２取付座３，５は、車室側に開口する有底箱状の取付座本体９を備えている。この取付座本体９は、上記取付座収容部７に対応する略半楕円形状で、その開口周縁部には取付座本体９の開口を閉じるリッド１１が薄肉ヒンジ１３を介して一体に形成されている。また、この取付座本体９の底壁部にはボルト挿通孔９ａが貫通形成されており、このボルト挿通孔９ａを車体パネルＰのボルト挿通孔ｐ１に一致させ、両ボルト挿通孔９ａ，ｐ１に取付ボルトＢを挿通して、車体パネルＰ裏面の上記ウェルドナットＮに螺合締結することにより、第１及び第２取付座３，５が車体パネルＰに取付け固定されている。なお、図示しないが、ボルト・ナット結合に代え、取付座本体９裏面に可撓性の係止爪を一体に突設し、この係止爪を車体パネルＰの係止孔に挿入してその周縁部に係止させることで、第１及び第２取付座３，５を車体パネルＰに取付け固定するようにしてもよい。
【００１８】
次に、上記第１及び第２取付座３，５の異なる構造部分について説明すると、第１取付座３の取付座本体９下端側壁の開口側端部には、図７に示すように、グリップ本体１の長さ方向に延びる断面円形の筒状支持部１５が一体に形成されている。この筒状支持部１５には図示しない支持軸が嵌挿され、この支持軸と筒状支持部１５との間には、例えばシリコン等の高粘度（１０００００ｃｐｓ以上が望ましい）の粘性流体が充填されている。そして、この粘性流体の粘性によりグリップ本体１が使用位置から格納位置へ回動するときの回動抵抗となるトルクを発生し、グリップ本体１の回動動作を緩行させるダンパー装置を構成している。
【００１９】
一方、第２取付座５の取付座本体９下端側壁の開口側端部には、図５及び図７に示すように、上記取付座収容部７に収容されてグリップ本体１の長さ方向に延びる筒状のコイルばね体収納部１７が一体に形成されている。このコイルばね体収納部１７には、グリップ本体１を使用位置から格納位置に回動させる捻りコイルばねからなるコイルばね体１９が収納されている。このコイルばね体１９は、図１、図２及び図４にも示すように、その長さ方向両端部の外周から線材が平面視にてコイルばね体１９の長さ方向に略直交しかつ互いに略反対方向に延びる一対の第１延長部１９ａ及び第２延長部１９ｂを有している。
【００２０】
上記コイルばね体収納部１７は、開放された収納凹部２１を有するように一対の側壁部２３と底壁部２５とで構成され、上記両側壁部２３には軸孔２７がそれぞれ貫通形成されている。一方、上記第２脚部１ｂの取付座収容部７の外側壁部２９ａには貫通軸孔３１ａが貫通形成されているとともに、内側壁部２９ｂには有底軸孔３１ｂが形成されている。そして、上記コイルばね体１９をコイルばね体収納部１７の収納凹部２１内に配置した状態で、第２脚部１ｂの軸孔３１ａ，３１ｂとコイルばね体収納部１７の軸孔２７とに支持軸３３を串刺し状に嵌挿することにより、コイルばね体１９を第２脚部１ｂに組み付けるようになっている。
【００２１】
一方、上記取付座収容部７は、上記コイルばね体１９の長さ方向に略平行な開口辺部３５を有し、該開口辺部３５の長さ方向一端部には、図３にも示すように、上記コイルばね体１９の第１延長部１９ａを上記取付座収容部７の開口側から挿入する挿入溝３７が形成されている。また、上記開口辺部３５の取付座収容部７側には、上記挿入溝３７の底部３７ａから取付座収容部７内に向けて一体的に突出し上記挿入溝３７の底部３７ａと共に上記コイルばね体１９の第１延長部１９ａが圧接される座部３９が立設されている。この座部３９を設けたことがこの発明の特徴とするところである。さらに、上記挿入溝３７の一方の側壁部も取付座収容部７内に向けて突出して延出壁部４１を構成し、この延出壁部４１及び挿入溝３７の一方の側壁部上端には内側に向かって下傾する傾斜面４３が連続して形成されている。また、上記取付座収容部７には、上記挿入溝３７と略対角線の位置関係になるように挿入溝４５が形成され、この挿入溝４５に上記コイルばね体１９の第２延長部１９ｂが圧接されている。そして、コイルばね体１９の捩り力によってグリップ本体１は常時は格納位置に位置付けられるように使用位置から格納位置に向かう方向（図５で反時計回り方向）に回動付勢されている。
【００２２】
上記コイルばね体１９は第２取付座５に収納された状態でグリップ本体１の第２脚部１ｂに組み付けられる。その要領は、まず、コイルばね体１９を第２取付座５のコイルばね体収納部１７の収納空間２１内に収納し、第２延長部１９ｂを挿入溝４５に挿入する。次いで、図６に示すように、コイルばね体１９が収納された第２取付座５をコイルばね体１９が上になるように傾けて第２脚部１ｂの取付座収容部７内に収容し、コイルばね体１９の第１延長部１９ａを取付座収容部７の開口辺部３５に形成された挿入溝３７に傾斜面４３で案内しながら挿入してその底部３７ａに接触させる。
【００２３】
この際、第２取付座５がコイルばね体１９と共に開口辺部３５から遠ざかるように取付座収容部７内を動いても、上記第１延長部１９ａを挿入溝３７の底部３７ａから取付座収容部７内に向けて突出する座部３９で受けて第１延長部１９ａが取付座収容部７の内壁に当接するように落ち込まないようにすることができる。しかる後、支持軸３３を第２脚部１ｂの外側壁部２９ａ側から軸孔３１ａ，３１ｂに挿入し、該軸孔３１ａ，３１ｂとコイルばね体収納部１７の軸孔２７とに串刺し状に嵌挿することで、コイルばね体１９を第２脚部１ｂに確実に組み付けることができる。
【００２４】
また、コイルばね体１９の第１延長部１９ａを傾斜面４３で案内するので、第１延長部１９ａをスムーズに挿入溝３７に挿入することができるとともに、上記第１延長部１９ａの先端が上記挿入溝３７の底部３７ａよりも取付座収容部７の内側へずれた場合でも、取付座収容部７内に突出する延出壁部４１によって第１延長部１９ａを移動規制してコイルばね体１９の長さ方向上記内側壁部２９ｂ側への位置ズレを防止することができる。
【００２５】
なお、上記の実施の形態では、グリップ本体１の第１脚部１ａ側に粘性ダンパを設け、第２脚部１ｂ側にコイルばね体１９を組み付けたが、これとは逆に、第１脚部１ａ側にコイルばね体１９を組み付け、第２脚部１ｂ側に粘性ダンパを設けてもよく、また、第１及び第２脚部１ａ，１ｂの両方に粘性ダンパ及びコイルばね体１９をそれぞれ併設するようにしてもよい。
【００２６】
また、挿入溝３７，座部３９，延出壁部４１及び傾斜面４３は、第２脚部１ｂの内側壁部２９ｂ寄りに設けてもよい。
【００２７】
さらに、内側壁部２９ｂ側の軸孔３１ｂを外側壁部２９ａ側の軸孔３１ａと同様に貫通形成してもよく、あるいは上記の実施形態とは逆に軸孔３１ａを有底軸孔に、軸孔３１ｂを貫通軸孔にしてもよい。
【００２８】
【発明の効果】
以上説明したように、この発明によれば、取付座収容部の開口辺部の長さ方向一端部に挿入溝を形成するとともに、上記開口辺部の取付座収容部側に上記挿入溝の底部から取付座収容部内に向けて突出し挿入溝の底部と共にコイルばね体の第１延長部が圧接される座部を立設したので、コイルばね体を収納した取付座が開口辺部から遠ざかるように取付座収容部内を動いても、上記第１延長部を座部で受けて取付座収容部内に落ち込まないようにすることができ、コイルばね体を脚部に確実に組み付けることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a retractable assist grip that is mounted on, for example, a vehicle, and stores a pivot body from a use position to a retracted position by a spring force of a coil spring body when not in use. Related to assembly measures.
[0002]
[Prior art]
Conventionally, as a retractable assist grip as described above, a pair of legs at both ends in a longitudinal direction of a long grip body are rotatably supported on a vehicle body or the like via respective mounting seats, and at least one of the legs is supported. A retractable assist grip in which a coil spring body is mounted between the leg and the mounting seat, and when not in use, the grip body is rotated from the use position to the storage position by the spring force of the coil spring body and stored. Is known (for example, see Patent Document 1).
[0003]
In Patent Literature 1 described above, a mounting seat receiving portion is formed on one of the legs of the grip main body so as to be opened on a surface facing the vehicle body panel when the grip main body is in the storage position and to store a part of the mounting seat. Have been. A coil spring body is disposed around a support shaft that supports the one leg portion with respect to the mounting seat, and an end of a wire rod extended from an outer periphery of one end in a longitudinal direction of the coil spring body. The end of the wire rod extending from the outer periphery of the other end of the coil spring body is also engaged with the mounting seat.
[0004]
[Patent Document 1]
JP-A-10-24759 (page 4, FIG. 12)
[0005]
[Problems to be solved by the invention]
However, generally, when the coil spring body is mounted between the leg and the mounting seat, the mounting seat housing the coil spring body in the coil spring housing portion is housed in the mounting seat housing portion of the leg portion, and the coil spring body is mounted. The one end side wire extension is inserted into an insertion groove formed in the opening side of the mounting seat accommodating portion and is brought into contact with the bottom thereof, and the other end side wire extension is brought into contact with the coil spring body accommodating portion. Since the support shaft is inserted through the leg, the mounting seat and the coil spring body, when the mounting seat is moved between the time when the mounting seat is arranged in the mounting seat receiving portion and the time when the support shaft is inserted, the mounting seat moves. In this case, the one end side wire rod extension of the coil spring body falls out of the insertion groove and falls into the mounting seat accommodating portion, so that the coil spring body cannot be assembled to the leg.
[0006]
The present invention has been made in view of such a point, and a purpose thereof is that even when the mounting seat moves in the mounting seat receiving portion, the one end side wire extension of the coil spring body does not fall into the mounting seat receiving portion. In this manner, the coil spring body is securely assembled to the leg.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the present invention is characterized by devising a structure around an insertion groove into which a wire extension of one end of a coil spring body is inserted.
[0008]
Specifically, the present invention provides an elongated grip body having legs at both ends in a length direction, and a pair of mounting seats each rotatably supporting the legs and being fixed to a fixed body. And a coil spring body provided between at least one leg of the grip body and the mounting seat, and rotating the grip body from the use position to the storage position. We took such a solution.
[0009]
That is, the present invention provides a mounting seat receiving portion which is provided on one of the legs of the grip main body and which is opened on a surface facing the fixed body when the grip main body is in the storage position to receive a part of the mounting seat. The mounting seat corresponding to the one leg is integrally formed with a cylindrical coil spring body housing portion that is housed in the mounting seat housing portion and extends in the length direction of the grip body. The spring body has a pair of first and second extension parts from the outer periphery of both ends in the longitudinal direction, where the wire material is substantially orthogonal to the longitudinal direction of the coil spring body and extends in directions substantially opposite to each other in plan view. The mounting seat accommodating portion has at least an opening side substantially parallel to the length direction of the coil spring body, and a first extension portion of the coil spring body at one end in the length direction of the opening side portion. An insertion groove for inserting the mounting seat from the opening side of the mounting seat receiving portion is formed. A seat portion protruding from the bottom of the insertion groove toward the inside of the mounting seat receiving portion and being in contact with the first extension of the coil spring body together with the bottom of the insertion groove is provided upright on the mounting seat receiving portion side of the opening side. The second extension of the coil spring is pressed against the coil spring housing.
[0010]
With the above configuration, in the present invention, the mounting seat housing the coil spring body is housed in the mounting seat housing portion of the leg, and the first extension of the coil spring body is formed on the opening side of the mounting seat housing portion. Even if the mounting seat is moved in the mounting seat receiving part so as to move away from the opening side while the second extension part is in contact with the coil spring body storing part while being inserted into the insertion groove and making contact with the bottom thereof, The extension portion is received by a seat protruding from the bottom of the insertion groove toward the inside of the mounting seat receiving portion, does not fall into the mounting seat receiving portion, and the coil spring body is securely assembled to the leg portion.
