【発明の属する技術分野】
本発明は、樹脂製部材をボルト・ナットを用いて樹脂製部材と別の部材に取り付ける場合に、樹脂製部材のボルト穴にカラーが装着されるカラーと樹脂製部材からなる取付構造体に関する。
【０００２】
【従来の技術】
従来のカラー１は、図４に示すように、筒形状であり、樹脂製部材２のボルト穴２ａに装着される。カラー１の軸方向長さは、樹脂製部材２のボルト穴２ａ部位の厚さより、０〜０．３ｍｍ程度長く設定されている。その理由は、樹脂製部材２（たとえば、自動車用シフトレバー装置のベースプレート）を樹脂製部材２と別の部材３（たとえば、自動車のフロアボデー）に取り付ける時に、樹脂製部材２にボルト・ナット４の締めつけ力がかかって樹脂製部材２に過大な応力が生じないようにするためである。
【０００３】
【発明が解決しようとする課題】
しかし、従来のカラーと樹脂製部材からなる取付構造体にはつぎの問題がある。
カラー１の軸方向長さが樹脂製部材２のボルト穴２ａ部位の厚さよりも長く設定されているので、樹脂製部材２と、ワッシャ（またはボルトの頭部の裏面）４ａまたは別の部材３との間に隙間Ｓが生じる。そのため、樹脂製部材２に強い力がかかると、樹脂製部材２が隙間Ｓの範囲内で、カラー１に対して移動し、別の部材３に対してがたつくおそれがある。
本発明の目的は、樹脂製部材が樹脂製部材と別の部材に対してがたつくことを防止できるカラーと樹脂製部材からなる取付構造体を提供することにある。
【０００４】
【課題を解決するための手段】
上記目的を達成する本発明はつぎの通りである。
（１）樹脂製部材をボルト・ナットを用いて前記樹脂製部材と別の部材に取り付ける場合に前記樹脂製部材のボルト穴にカラーが装着されるカラーと樹脂製部材からなる取付構造体であって、
前記カラーは、筒部と該筒部の軸方向の一端部から半径方向外側に延びるフランジ部とを有し、前記筒部の軸方向の他端の面は前記樹脂製部材の表側面と面一となっており、前記フランジ部の前記別の部材との当接面と反対側の面は前記樹脂製部材の前記フランジ部との当接面を溶かし込んで前記樹脂製部材の前記フランジ部との当接面に押し付けられており、前記フランジ部の前記別の部材との当接面は前記樹脂製部材の裏側面から突出している、カラーと樹脂製部材からなる取付構造体。
（２）前記カラーは前記樹脂製部材への装着時に前記樹脂製部材の前記フランジ部に当たる面を軟化または溶融可能な温度に昇温されている（１）記載のカラーと樹脂製部材からなる取付構造体。
（３）前記樹脂製部材は自動車用シフトレバー装置のベースプレートであり、前記別の部材は自動車のフロアボデーである（１）記載のカラーと樹脂製部材からなる取付構造体。
（４）前記樹脂製部材の、前記カラーのフランジ部に対応する部分に、前記フランジ部を受け入れる凹部が形成されている（１）記載のカラーと樹脂製部材からなる取付構造体。
【０００５】
上記（１）〜（４）のカラーと樹脂製部材からなる取付構造体では、樹脂製部材の表側面はワッシャまたはボルトの頭部の裏面により押えられ、樹脂製部材のフランジ部との当接面はフランジ部により押えられ、樹脂製部材のカラー周囲部分は、ワッシャまたはボルト頭部裏面と、フランジ部の別の部材との当接面と反対側の面とによって挟まれるので、樹脂製部材がカラーに対して移動できず、樹脂製部材が樹脂製部材と別の部材に対してがたつくのを防止できる。
【０００６】
【発明の実施の形態】
図１は、本発明の第１実施例のカラーと樹脂製部材からなる取付構造体を示しており、図２は、本発明の第２実施例のカラーと樹脂製部材からなる取付構造体を示しており、図３は、本発明の第１実施例と第２実施例の両実施例に適用できるカラーが自動車用シフトレバー装置のベースプレートに圧入される場合を示している。
本発明の第１実施例と第２実施例に共通する部分には、本発明の第１実施例と第２実施例の両実施例にわたって同じ符号を付してある。
まず、本発明の第１実施例と第２実施例にわたって共通する部分を、図１、図３を参照して、説明する。
本発明実施例のカラー１０は、図１に示すように、ボルト・ナット２０を用いて、樹脂製部材３０を樹脂製部材３０と別の部材（以下、別部材という）４０に取り付ける場合に、樹脂製部材３０のボルト穴３２に装着される。
【０００７】
カラー１０は、樹脂製部材３０のボルト穴３２に装着される。カラー１０は、樹脂製部材３０への装着時に、樹脂製部材３０の後述のフランジ部１２との当接面３３を軟化または溶融可能な温度にまで昇温された状態で、樹脂製部材３０に装着される。ここで、樹脂製部材３０のフランジ部１２との当接面３３を軟化または溶融可能な温度とは、約１００°Ｃ〜約２７０°Ｃである。
【０００８】
カラー１０は、金属製であり、筒部１１と、筒部１１の別部材４０側の端部から半径方向外側に延びるフランジ部１２とを有する。
筒部１１の外周面に、図示略のローレットが設けられている。筒部１１の軸方向長さＬ1 は、樹脂製部材３０のボルト取付け部３１の厚さＬ2 よりも小とされている。筒部１１は、樹脂製部材３０のボルト取付け部３１のボルト穴３２に装着される。筒部１１の別部材４０側と反対側の端面１１ａは、樹脂製部材３０のボルト取付け部３１の表側面３１ａと面一となっている。
フランジ部１２の、別部材４０との当接面１２ａと反対側の面１２ｂは、樹脂製部材３０のフランジ部１２との当接面３３を溶かし込んで、当接面３３に押しつけられている。フランジ部１２の、別部材４０との当接面１２ａは、樹脂製部材３０の裏側面３１ｂから別部材４０側に突出している。
【０００９】
樹脂製部材３０は、たとえば、自動車用シフトレバー装置のベースプレートである。樹脂製部材３０は、たとえばＡＢＳ樹脂製である。樹脂製部材３０は、ボルト取付け部３１が設けられている。ボルト取付け部３１には、ボルト穴３２が形成されている。ボルト取付け部３１の表側面（ボルト取付け部３１の別部材４０と対向する面と反対側の面）３１ａは、カラー１０の筒部１１の端面１１ａと面一となっている。ボルト取付け部３１の、ボルト穴３２にカラー１０が装着された時、フランジ部１２が当たる面３３（以下、当接面３３という）は、フランジ部１２により軟化または溶融される。樹脂製部材３０は、フランジ部１２に対応する部分にフランジ部１２を受け入れる凹部（以下、ざぐりという）３４が設けられていてもよい。樹脂製部材３０は、ボルト穴３２の軸方向両端部の直径が、対応するカラー１０の部位の直径よりも大とされていてもよい。
別部材４０は、たとえば、金属製の部材である。別の部材４０は、たとえば、自動車のフロアボデーである。別部材４０は、ボルト挿通用の穴部４１を有している。
【００１０】
ここで、樹脂製部材３０の別部材４０への取付け手順を説明する。
まず、カラー１０を、樹脂製部材３０のフランジ部１２との当接面３３を軟化または溶融させる温度まで温度を上げる。
温度を上げたカラー１０を、樹脂製部材３０のボルト穴３２に装着する。カラー１０をボルト穴３２に装着する時、ボルト取付け部３１の表側面３１ａと筒部１１の端面１１ａとが面一となる前に、フランジ部１２の面１２ｂが樹脂製部材３０のフランジ部１２との当接面３３に当たる。カラー１０は温度が上げられているので、樹脂製部材３０のうちフランジ部１２と当たる部位は、カラー１０により、軟化または溶融する。
【００１１】
フランジ部１２が樹脂製部材３０に当たった後、さらにカラー１０を装着すると、カラー１０は、フランジ部１２が樹脂製部材３０を軟化または溶融させながら、ボルト穴３２に入っていく。カラー１０は、筒部１１の端面１１ａがボルト取付け部３１の表側面３１ａと面一になる位置に装着される。
カラー１０を樹脂製部材３０に装着した時、フランジ部１２の面１２ｂは樹脂製部材３０に融着している。また、フランジ部１２の、別部材４０との当接面１２ａは、樹脂製部材３０の裏側面３１ｂよりも別部材４０側に突出している。
【００１２】
筒部１１の端面１１ａがボルト取付け部３１の表側面３１ａと面一になるまで、カラー１０をボルト穴３２に装着した後、カラー１０を冷却する。冷却後、カラー１０の筒部１１の軸芯を別部材４０の穴部４１の軸芯に合わせ、ボルト・ナット２０で樹脂製部材３０を別部材４０に取り付ける。
【００１３】
つぎに、作用を説明する。
本発明実施例では、カラー１０の筒部１１の端面１１ａは樹脂製部材３０の表側面３１ａと面一となっており、フランジ部１２の面１２ｂは樹脂製部材３０のフランジ部１２との当接面３３を溶かし込んで当接面３３に押し付けられており、フランジ部１２の、別部材４０との当接面１２ａは樹脂製部材３０の裏側面３１ｂから別部材４０側に突出している。そのため、樹脂製部材３０の表側面３１ａはワッシャ（またはボルトの頭部の裏面）２１により押えられ、樹脂製部材３０のフランジ部１２との当接面３３はフランジ部１２により押えられ、樹脂製部材３０のカラー１０周囲部分であるボルト取付け部３１は、ワッシャ（またはボルト頭部裏面）２１と、フランジ部１２の面１２ｂによって挟まれるので、樹脂製部材３０がカラー１０に対して移動できず、樹脂製部材３０が別部材４０に対してがたつくのを防止できる。２１により押え、樹脂製部材３０の裏側面３１ｂをフランジ部１２により押えることができる。そのため、樹脂製部材３０がカラー１０に対して移動することはなく、樹脂製部材３０が別部材４０に対してがたつくことはない。
【００１４】
また、図３に示すように、１つの樹脂製部材３０に複数のボルト取付け部３１が設けられている場合、成形誤差等により、それぞれのボルト取付け部３１の厚さが異なることが考えられる。しかし、そのような場合でも、図１に示すように、カラー１０（カラー１０は切削加工で寸法が高精度にでている）のフランジ部１２が樹脂製部材３０に溶け込むので、樹脂製部材３０の誤差は、フランジ部１２が樹脂製部材３０に溶け込む軸方向長さｈで吸収できる。そのため、１つの樹脂製部材３０に複数のボルト取付け部３１が設けられている場合でも、それぞれのボルト取付け部３１の表側面３１ａの、別部材４０からの高さを等しくすることができ、ボルト・ナット２０による締め付け後に、樹脂製部材３０が別部材４０に対してがたつくことはない。樹脂製部材３０が自動車用シフトレバー装置のベースプレートであり、別部材４０が自動車のフロアボデーである場合、ベースプレートには複数のボルト取付け部が設けられるが、ベースプレートがフロアボデーに対してがたつくことはない。
【００１５】
つぎに、本発明の各実施例に特有な部分を説明する。
本発明の第１実施例では、図１に示すように、樹脂製部材３０のフランジ部１２に対応する部分にざぐり３４が設けられている場合を示している。ざぐり３４が設けられている部位の直径Ｄ1 は、カラー１０のフランジ部１２の直径Ｄ2 よりも大とされている。ボルト穴３２の表側面３１ａ側の端部３２ａの直径Ｄ3 は、カラー１０の軸部１１の直径Ｄ4 よりも大とされている。ボルト穴３２の端部３２ａの直径は、ワッシャ（またはボルト頭部裏面）２１の直径Ｄ5 よりも小とされている。
【００１６】
ざぐり３４が設けられている部位の直径Ｄ1 は、フランジ部１２の直径Ｄ2 よりも大とされており、ボルト穴３２の表側面３１ａ側の端部３２ａの直径Ｄ3 はカラー１０の軸部１１の直径Ｄ4 よりも大とされているので、樹脂製部材３０とカラー１０との間の空間を、溶けた樹脂（樹脂のかす）の逃げ部Ａとすることができる。そのため、カラー１０をボルト穴３２に装着することによって溶けた樹脂がボルト・ナット２０で挟みこまれるワッシャ（またはボルト頭部裏面）２１と別部材４０との間に入り込むことを防止することができる。
【００１７】
本発明の第２実施例では、図２に示すように、樹脂製部材３０のフランジ部１２に対応する部分にざぐり３４が設けられていない場合を示している。ボルト穴３２の表側面３１ａ側の端部３２ａの直径Ｄ3 は、カラー１０の軸部１１の直径と同じかまたはほぼ同じとされている。
【００１８】
ざぐり３４が設けられていないので、カラー１０を樹脂製部材３０のボルト穴３２に装着し、フランジ部１２が樹脂製部材３０に溶け込んだ時、フランジ部１２の当接面１２ａと樹脂製部材３０の裏側面３１ｂとの間の空間を、溶けた樹脂（樹脂のかす）の逃げ部Ａとすることができる。そのため、カラー１０をボルト穴３２に装着することによって溶けた樹脂がボルト・ナット２０で挟みこまれるワッシャ（またはボルト頭部裏面）２１と別部材４０との間に入り込むことを防止することができる。
【００１９】
【発明の効果】
請求項１または請求項２または請求項３または請求項４記載のカラーと樹脂製部材からなる取付構造体によれば、樹脂製部材の表側面はワッシャまたはボルトの頭部の裏面により押えられ、樹脂製部材のフランジ部との当接面はフランジ部により押えられ、樹脂製部材のカラー周囲部分は、ワッシャまたはボルト頭部裏面と、フランジ部の別の部材との当接面と反対側の面とによって挟まれるので、樹脂製部材がカラーに対して移動できず、樹脂製部材が樹脂製部材と別の部材に対してがたつくのを防止できる。

Portions common to the first embodiment and the second embodiment of the present invention are denoted by the same reference numerals throughout both the first and second embodiments of the present invention.
First, parts common to the first and second embodiments of the present invention will be described with reference to FIGS.
As shown in FIG. 1, the collar 10 of the embodiment of the present invention uses a bolt / nut 20 to attach the resin member 30 to the resin member 30 and another member (hereinafter referred to as another member) 40. It is mounted in the bolt hole 32 of the resin member 30.
[0007]
The collar 10 is mounted in the bolt hole 32 of the resin member 30. When the collar 10 is attached to the resin member 30, the resin member 30 is heated to a temperature at which a contact surface 33 of the resin member 30 with a flange portion 12 described later can be softened or melted. Installed. Here, the temperature at which the contact surface 33 with the flange portion 12 of the resin member 30 can be softened or melted is about 100 ° C. to about 270 ° C.
[0008]
The collar 10 is made of metal, and includes a cylindrical portion 11 and a flange portion 12 that extends radially outward from an end portion of the cylindrical portion 11 on the side of another member 40.
A knurling (not shown) is provided on the outer peripheral surface of the cylindrical portion 11. The axial length L1 of the cylindrical portion 11 is set to be smaller than the thickness L2 of the bolt mounting portion 31 of the resin member 30. The cylinder portion 11 is mounted in the bolt hole 32 of the bolt mounting portion 31 of the resin member 30. An end surface 11 a opposite to the other member 40 side of the cylindrical portion 11 is flush with the front side surface 31 a of the bolt mounting portion 31 of the resin member 30.
The surface 12 b of the flange portion 12 opposite to the contact surface 12 a with the separate member 40 melts the contact surface 33 with the flange portion 12 of the resin member 30 and is pressed against the contact surface 33. . The contact surface 12 a of the flange portion 12 with the separate member 40 protrudes from the back side surface 31 b of the resin member 30 to the separate member 40 side.
[0009]
The resin member 30 is, for example, a base plate of an automobile shift lever device. The resin member 30 is made of ABS resin, for example. The resin member 30 is provided with a bolt mounting portion 31. Bolt holes 32 are formed in the bolt mounting portion 31. A front side surface (surface opposite to the surface facing the other member 40 of the bolt mounting portion 31) 31 a of the bolt mounting portion 31 is flush with the end surface 11 a of the cylindrical portion 11 of the collar 10. When the collar 10 is mounted in the bolt hole 32 of the bolt mounting portion 31, a surface 33 (hereinafter referred to as a contact surface 33) with which the flange portion 12 abuts is softened or melted by the flange portion 12. The resin member 30 may be provided with a concave portion (hereinafter referred to as a counterbore) 34 that receives the flange portion 12 at a portion corresponding to the flange portion 12. The resin member 30 may have a diameter at both ends in the axial direction of the bolt hole 32 larger than the diameter of the corresponding portion of the collar 10.
The separate member 40 is, for example, a metal member. Another member 40 is, for example, an automobile floor body. The separate member 40 has a hole 41 for inserting a bolt.
[0010]
Here, a procedure for attaching the resin member 30 to the separate member 40 will be described.
First, the temperature of the collar 10 is increased to a temperature at which the contact surface 33 with the flange portion 12 of the resin member 30 is softened or melted.
The collar 10 whose temperature has been raised is mounted in the bolt hole 32 of the resin member 30. When the collar 10 is mounted in the bolt hole 32, the surface 12 b of the flange portion 12 is in contact with the flange portion 12 of the resin member 30 before the front side surface 31 a of the bolt mounting portion 31 and the end surface 11 a of the cylindrical portion 11 are flush with each other. It contacts the contact surface 33. Since the temperature of the collar 10 is raised, the portion of the resin member 30 that contacts the flange portion 12 is softened or melted by the collar 10.
[0011]
When the collar 10 is further mounted after the flange portion 12 hits the resin member 30, the collar 10 enters the bolt hole 32 while the flange portion 12 softens or melts the resin member 30. The collar 10 is mounted at a position where the end surface 11 a of the cylinder portion 11 is flush with the front side surface 31 a of the bolt mounting portion 31.
When the collar 10 is attached to the resin member 30, the surface 12 b of the flange portion 12 is fused to the resin member 30. Further, the contact surface 12 a of the flange portion 12 with the separate member 40 protrudes to the separate member 40 side from the back side surface 31 b of the resin member 30.
[0012]
After the collar 10 is mounted in the bolt hole 32 until the end surface 11a of the tube portion 11 is flush with the front side surface 31a of the bolt mounting portion 31, the collar 10 is cooled. After cooling, the axial center of the cylindrical portion 11 of the collar 10 is aligned with the axial center of the hole 41 of the separate member 40, and the resin member 30 is attached to the separate member 40 with the bolts and nuts 20.
[0013]
Next, the operation will be described.
In the embodiment of the present invention, the end surface 11 a of the cylindrical portion 11 of the collar 10 is flush with the front side surface 31 a of the resin member 30, and the surface 12 b of the flange portion 12 is in contact with the flange portion 12 of the resin member 30. The contact surface 33 is melted and pressed against the contact surface 33, and the contact surface 12 a of the flange portion 12 with the separate member 40 protrudes from the back side surface 31 b of the resin member 30 to the separate member 40 side. Therefore, the front side surface 31a of the resin member 30 is pressed by the washer (or the back surface of the head of the bolt) 21, and the contact surface 33 with the flange portion 12 of the resin member 30 is pressed by the flange portion 12 to be made of resin. Since the bolt mounting portion 31 that is the peripheral portion of the collar 10 of the member 30 is sandwiched between the washer (or the bolt head rear surface) 21 and the surface 12b of the flange portion 12, the resin member 30 cannot move relative to the collar 10. It is possible to prevent the resin member 30 from rattling against the separate member 40. 21, and the back side surface 31 b of the resin member 30 can be pressed by the flange portion 12. Therefore, the resin member 30 does not move relative to the collar 10, and the resin member 30 does not rattle against the separate member 40.
[0014]
Moreover, as shown in FIG. 3, when the several bolt attachment part 31 is provided in the one resin-made member 30, it is possible that the thickness of each bolt attachment part 31 differs by a shaping | molding error etc. FIG. However, even in such a case, as shown in FIG. 1, the flange portion 12 of the collar 10 (the size of the collar 10 is high by cutting) melts into the resin member 30. This error can be absorbed by the axial length h at which the flange portion 12 melts into the resin member 30. Therefore, even when a plurality of bolt mounting portions 31 are provided on one resin member 30, the height of the front side surface 31a of each bolt mounting portion 31 from the separate member 40 can be made equal. The resin member 30 does not rattle against the separate member 40 after being tightened by the nut 20. When the resin member 30 is a base plate of a shift lever device for an automobile and the separate member 40 is a floor body of an automobile, the base plate is provided with a plurality of bolt mounting portions. Absent.
[0015]
Next, parts specific to each embodiment of the present invention will be described.
In the first embodiment of the present invention, as shown in FIG. 1, a case is shown in which a counterbore 34 is provided in a portion corresponding to the flange portion 12 of the resin member 30. The diameter D1 of the portion where the counterbore 34 is provided is larger than the diameter D2 of the flange portion 12 of the collar 10. The diameter D3 of the end portion 32a on the front side surface 31a side of the bolt hole 32 is larger than the diameter D4 of the shaft portion 11 of the collar 10. The diameter of the end portion 32a of the bolt hole 32 is smaller than the diameter D5 of the washer (or the back surface of the bolt head) 21.
[0016]
The diameter D1 of the portion where the counterbore 34 is provided is larger than the diameter D2 of the flange portion 12, and the diameter D3 of the end portion 32 a on the front side surface 31 a side of the bolt hole 32 is the diameter of the shaft portion 11 of the collar 10. Since the diameter is larger than the diameter D4, the space between the resin member 30 and the collar 10 can be used as an escape portion A for melted resin (resin debris). Therefore, the resin melted by mounting the collar 10 in the bolt hole 32 can be prevented from entering between the washer (or the back surface of the bolt head) 21 and the separate member 40 sandwiched between the bolts and nuts 20. .
[0017]
In the second embodiment of the present invention, as shown in FIG. 2, a case is shown in which a spot 34 is not provided in a portion corresponding to the flange portion 12 of the resin member 30. The diameter D3 of the end portion 32a on the front side 31a side of the bolt hole 32 is the same as or substantially the same as the diameter of the shaft portion 11 of the collar 10.
[0018]
Since the counterbore 34 is not provided, when the collar 10 is mounted in the bolt hole 32 of the resin member 30 and the flange portion 12 is melted into the resin member 30, the contact surface 12 a of the flange portion 12 and the resin member 30. The space between the rear side surface 31b of the resin can be used as a relief portion A for melted resin (resin dregs). Therefore, the resin melted by mounting the collar 10 in the bolt hole 32 can be prevented from entering between the washer (or the back surface of the bolt head) 21 and the separate member 40 sandwiched between the bolts and nuts 20. .
