Description

本発明は、樹脂製の第１部材及び第２部材をタッピングスクリューで固定する二部材の取付構造に関する。 The present invention relates to a two-member mounting structure for fixing a first member made of resin and a second member with a tapping screw.

この種の二部材の取付構造の一例が特許文献１に開示されている。すなわち、樹脂製の第１部材の表面には、円形のネジ締結穴が形成された円筒状のボスが形成されている。一方、樹脂製の第２部材の上記ボス対応箇所には、円筒状の筒状部が形成されており、該筒状部の中央には、第１部材のボスよりも大径の貫通孔が形成されている。この貫通孔に第１部材のボスが裏面側から挿通し、かつ貫通孔よりも大径の頭部を有する取付ネジの軸部が第２部材の表面側から挿通して第１部材のネジ締結穴に螺合した状態で、両部材が取り付けられる。しかしながら、この取付構造では、両部材を取り付ける際に、第２部材のボスを第１部材の筒状部に挿通させた状態を保ちつつ、取付ネジを螺合させなければならないため、取付作業が困難である。 An example of this type of two-member mounting structure is disclosed in Patent Document 1. That is, a cylindrical boss having a circular screw fastening hole is formed on the surface of the first resin member. On the other hand, a cylindrical tubular portion is formed at the boss corresponding portion of the resin-made second member, and a through-hole having a diameter larger than that of the boss of the first member is formed at the center of the tubular portion. Is formed. The boss of the first member is inserted into the through hole from the back surface side, and the shaft portion of the mounting screw having a head having a diameter larger than that of the through hole is inserted from the front surface side of the second member, and the screw of the first member is fastened. Both members are attached in a state of being screwed into the hole. However, in this mounting structure, when both members are mounted, the mounting screw must be screwed while maintaining the state in which the boss of the second member is inserted through the cylindrical portion of the first member. Have difficulty.

そこで、第１部材を第２部材に仮固定した状態で固定する取付構造がある。その一例が特許文献２に開示されている。この取付構造は、ドアトリム（第２部材）にアームレスト（第１部材）を取り付けるものであり、アームレストの裏面には、取付用ボスと、この取付用ボスから離間して係止用ボスが別途設けられている。係止用ボスは、筒状をなし、その先端部に係止爪が形成されている。一方、ドアトリムには、取付用ボスに対応する箇所にタッピングスクリュー挿通孔が形成されていると共に、係止用ボスに対応する箇所に係止孔が形成されている。アームレストをドアトリムに取り付ける際には、先ず、アームレストの係止用ボスをドアトリムの係止孔に係止させる。これにより、アームレストがドアトリムに仮固定される。次いで、ドアトリムの裏面側からタッピングスクリュー挿通孔にタッピングスクリューを挿通し、アームレストの取付用ボスにねじ込ませる。これにより、アームレストがドアトリムに取り付けられる。 Therefore, there is an attachment structure in which the first member is fixed to the second member in a temporarily fixed state. An example thereof is disclosed in Patent Document 2. In this mounting structure, an armrest (first member) is attached to a door trim (second member), and a mounting boss and a locking boss are provided separately from the mounting boss on the back surface of the armrest. It has been. The locking boss has a cylindrical shape, and a locking claw is formed at the tip of the locking boss. On the other hand, the door trim has a tapping screw insertion hole formed at a position corresponding to the mounting boss, and a locking hole formed at a position corresponding to the locking boss. When attaching the armrest to the door trim, first, the locking boss of the armrest is locked in the locking hole of the door trim. Thereby, an armrest is temporarily fixed to a door trim. Next, the tapping screw is inserted into the tapping screw insertion hole from the back surface side of the door trim and screwed into the mounting boss of the armrest. Thereby, an armrest is attached to a door trim.

すなわち、第１の発明は、上記第１部材は、上記第２部材側に向かって突設され、上記タッピングスクリューが螺合するネジ孔が形成された第１取付座を有し、上記第２部材は、上記第１部材側に開放されて上記第１取付座を収容する収容凹部が形成された第２取付座と、上記第１取付座と係合する係合片と、を有し、上記収容凹部の底壁部には、上記タッピングスクリューが挿通する挿通孔が形成されており、上記第１部材は、上記第１取付座が上記収容凹部の開口から該収容凹部に収容され、上記係合片が上記第１取付座と係合し、かつ上記タッピングスクリューが上記挿通孔を挿通して上記ネジ孔にねじ込まれた状態で、上記第２部材に取り付けられ、上記第２取付座は、上記収容凹部の開口周縁から突設されていると共に、上記係合片に対応するように側方に開口して上記収容凹部と連通する開放口が形成され、上記挿通孔は、上記開放口側に開口する切欠状に形成され、上記係合片は、上記収容凹部の開口の上記開放口側の周縁における上記挿通孔に対応する箇所から上記開放口の内側に向けて延びていることを特徴とする。 That is, in the first invention, the first member has a first mounting seat that protrudes toward the second member side and has a screw hole into which the tapping screw is screwed. The member has a second mounting seat that is open to the first member side and has an accommodation recess that houses the first mounting seat, and an engagement piece that engages with the first mounting seat. An insertion hole through which the tapping screw is inserted is formed in the bottom wall portion of the accommodation recess, and the first member is accommodated in the accommodation recess from the opening of the accommodation recess, the engagement piece is engaged with the first mounting seat, and in a state in which the tapping screw is screwed into the screw hole by inserting the insertion hole is attached to the second member, said second mounting seat , Projecting from the opening periphery of the receiving recess, and the engagement An opening opening is formed to open to the side so as to correspond to the receiving recess, the insertion hole is formed in a notch shape opening to the opening opening side, and the engagement piece is formed of the receiving recess. It is characterized by extending toward the inside of the opening from a position corresponding to the insertion hole at the periphery of the opening on the opening side .

第２の発明は、第１の発明において、上記第１取付座は、側方に開口する開口部が形成された第１取付座基部と、該第１取付座基部から上記第２部材側に突出すると共に、上記ネジ孔が形成されたボスと、を有し、上記第１部材は、上記開口部の周縁部が上記係合片に係止した状態で、上記第２部材に取り付けられていることを特徴とする。 According to a second invention, in the first invention, the first mounting seat includes a first mounting seat base portion having an opening that opens laterally, and the first mounting seat base portion to the second member side. The first member is attached to the second member with the peripheral edge of the opening being locked to the engagement piece. It is characterized by being.

第３の発明は、第１の発明において、上記第１取付座には、側方に突出する突起が設けられ、上記第１部材は、上記突起が上記係合片に係止した状態で、上記第２部材に取り付けられていることを特徴とする。 According to a third invention, in the first invention, the first mounting seat is provided with a protrusion protruding laterally, and the first member is in a state where the protrusion is locked to the engagement piece, It is attached to the second member .

第１の発明によれば、第１部材を第２部材に取り付ける際には、先ず、第１部材の第１取付座を第２部材の収容凹部の開口から該収容凹部に収容する。この収容過程で、第２部材の係合片が第１取付座に係合する。これにより、第１部材が第２部材に仮固定される。次いで、第２取付座の挿通孔にタッピングスクリューを挿通し、第１取付座のネジ孔にねじ込む。これにより、第１部材が第２部材に固定される。このように、タッピングスクリューで固定する際に第１部材を第２部材に仮固定することができるので、取付作業が容易となる。 According to the first invention, when the first member is attached to the second member, first, the first attachment seat of the first member is accommodated in the accommodation recess from the opening of the accommodation recess of the second member.

上記第１部材１は、板状の第１部材本体５を有し、また、上記第２部材３は、該第１部材本体５と平行な板状の第２部材本体７を有している。なお、以下では、これら第１部材本体５及び第２部材本体７の対向方向を上下方向とし、上記第２部材３側を上側、上記第１部材１側を下側とする。また、図１及び図３の紙面手前側及び紙面奥側をそれぞれ前側及び後側とする。 The first member 1 has a plate-like first member main body 5, and the second member 3 has a plate-like second member main body 7 parallel to the first member main body 5. . In the following description, the opposing direction of the first member main body 5 and the second member main body 7 is the vertical direction, the second member 3 side is the upper side, and the first member 1 side is the lower side. Also, the front side and the back side of the paper in FIGS. 1 and 3 are the front side and the rear side, respectively.

上記第１部材１は、例えばポリプロピレンで構成され、上記第１部材本体５の幅方向両端には、それぞれ上方に突出するリブ５ａ，５ａが設けられている。該第１部材本体５の上面には、上方に突出する第１取付座８が形成されている。該第１取付座８は、中空部１１を有する四角錐台状をなす第１取付座基部９を有し、この第１取付座基部９の側壁部１３には、前方（図１及び図３における紙面手前側）に開口し、かつ上記中空部１１に連通する矩形状開口部１５が形成されている。上記側壁部１３の上方を覆う矩形状の上壁部１７の中央部には、上記第１取付座基部９の約半分ほどの高さを有する円筒状のボス１９が上方に向けて突設されている。該ボス１９の中央には、該ボス１９及び上記上壁部１７を上下方向に貫通するネジ孔１９ａが形成されている。 The first member 1 is made of, for example, polypropylene, and ribs 5a and 5a protruding upward are provided at both ends in the width direction of the first member main body 5, respectively. A first mounting seat 8 that protrudes upward is formed on the upper surface of the first member body 5. The first mounting seat 8 has a first mounting seat base portion 9 having a quadrangular pyramid shape having a hollow portion 11, and the side wall portion 13 of the first mounting seat base portion 9 has a front (see FIGS. 1 and 3). A rectangular opening 15 is formed which opens to the front side of the paper and communicates with the hollow portion 11. A cylindrical boss 19 having a height that is about half the height of the first mounting seat base 9 protrudes upward from the center of the rectangular upper wall 17 that covers the upper side of the side wall 13. ing. At the center of the boss 19, a screw hole 19 a that penetrates the boss 19 and the upper wall portion 17 in the vertical direction is formed.

一方、上記第２部材３は、例えばポリプロピレンで構成されている。上記第２部材本体７の上記第１部材１のリブ５ａ，５ａに対応する箇所には、一対のリブ７ａ，７ａが下方に突出形成されている。上記第２部材本体７の上記第１取付座８対応箇所には、前後方向に細長い矩形状の連通孔２１（収容凹部の開口）が形成されており、該連通孔２１の周縁部から上方に向けて第２取付座２３が突設されている。該第２取付座２３は、上記第１取付座８を収容する収容凹部２５を有し、上記連通孔２１は、該収容凹部２５に連通している。該連通孔２１は、上記第１取付座基部９の少なくとも上半部分が挿通可能な面積を有している。 On the other hand, the second member 3 is made of, for example, polypropylene. A pair of ribs 7 a and 7 a are formed to protrude downward at locations corresponding to the ribs 5 a and 5 a of the first member 1 of the second member body 7. A rectangular communication hole 21 (opening of an accommodation recess) that is elongated in the front-rear direction is formed at a location corresponding to the first mounting seat 8 of the second member body 7, and upward from the peripheral edge of the communication hole 21. A second mounting seat 23 is provided so as to project. The second mounting seat 23 has a housing recess 25 for housing the first mounting seat 8, and the communication hole 21 communicates with the housing recess 25. The communication hole 21 has an area through which at least the upper half of the first mounting seat base 9 can be inserted.

上記第２取付座２３は、収容凹部２５を有する四角錐台状をなし、上記第１取付座８よりも高さ寸法が僅かに小さい。上記第２取付座２３の側壁部２７には、前方に開口し、かつ上記収容凹部２５に連通する矩形状の開放口２９が形成されている。該開放口２９は、上記側壁部２７の上方を覆う矩形状の上壁部３１（収容凹部の底壁部）の前端に達している。該上壁部３１には、その中央部後寄りから前方に延びて上記開放口２９側に開口する前後方向に細長い矩形状の切欠部３３（挿通孔）が形成されている。該切欠部３３の幅は、上記第１部材１のボス１９の径よりも小さく設定されている。 The second mounting seat 23 has a quadrangular frustum shape having an accommodation recess 25 and is slightly smaller in height than the first mounting seat 8. The side wall 27 of the second mounting seat 23 is formed with a rectangular opening 29 that opens forward and communicates with the housing recess 25. The opening 29 reaches the front end of a rectangular upper wall portion 31 (the bottom wall portion of the housing recess) that covers the side wall portion 27. The upper wall portion 31 is formed with a rectangular cutout 33 (insertion hole) that extends forward from the rear of the central portion and extends in the front-rear direction and opens toward the opening 29. The width of the notch 33 is set smaller than the diameter of the boss 19 of the first member 1.

一方、上記開放口２９は、下方に上記連通孔２１の前側の周縁まで延びている。該連通孔２１の前側の周縁には、矩形板状の係合片３５が上記開放口２９の内側に延びている。したがって、該係合片３５は、前後方向に撓むことができる。上記係合片３５は、上記側壁部２７の開放口２９側端に沿うように上側に向かって後方に傾斜するように上記第２取付座２３の高さ方向中央付近まで延びていて、その先端には、後方に突出する係合爪３５ａが形成されている。該係合爪３５ａは、図２に示すように、断面略三角形状をなし、下面が後上がりに傾斜する一方、上面が戦後方向に延びている。 On the other hand, the opening 29 extends downward to the front edge of the communication hole 21. A rectangular plate-like engagement piece 35 extends inward of the opening 29 at the front peripheral edge of the communication hole 21. Therefore, the engagement piece 35 can be bent in the front-rear direction. The engaging piece 35 extends to the vicinity of the center in the height direction of the second mounting seat 23 so as to incline backward toward the upper side along the end of the side wall portion 27 on the opening 29 side. Is formed with an engaging claw 35a protruding rearward. As shown in FIG. 2, the engaging claw 35 a has a substantially triangular cross section, and the lower surface is inclined upward and the upper surface extends in the post-war direction.

図４は第２部材３成形用の成形型を示す断面図である。上記第２取付座２３周辺部を成形する成形型３９は、上記第２部材３の表面側を成形する成形面４１ａを有する第１主型４１と、該第２部材３の裏面側を成形する成形面４３ａを有する第２主型４３と、を備えている。 FIG. 4 is a cross-sectional view showing a molding die for molding the second member 3. The molding die 39 for molding the peripheral portion of the second mounting seat 23 molds the first main mold 41 having the molding surface 41 a for molding the front surface side of the second member 3 and the back surface side of the second member 3. A second main mold 43 having a molding surface 43a.

ここで、図２〜図４に示すように、上記第２取付座２３は、上記連通孔２１の周縁から上方に突設されているため、該第２取付座２３は、上下方向において第２部材本体７に対してアンダーカット形状となっていない。一方、上記係合片３５は、上記連通孔２１の周縁から上方に延びているため、上下方向において上記第２部材本体７に対してアンダーカット形状となっていない。さらに、上記係合片３５の上方には、上記第２取付座２３の上壁部３１に形成された切欠部３３が位置しており、この切欠部３３が上記開放口２９側、即ち当該係合片３５側に開口しているので、上記係合片３５は、上下方向において上記第２取付座２３の上壁部３１に対してもアンダーカット形状となっていない。 Here, as shown in FIGS. 2 to 4, since the second mounting seat 23 protrudes upward from the peripheral edge of the communication hole 21, the second mounting seat 23 is second in the vertical direction. The member body 7 is not undercut. On the other hand, since the engagement piece 35 extends upward from the periphery of the communication hole 21, the engagement piece 35 does not have an undercut shape with respect to the second member body 7 in the vertical direction. Further, a notch 33 formed in the upper wall portion 31 of the second mounting seat 23 is located above the engagement piece 35, and the notch 33 is located on the opening 29 side, that is, the engagement portion. Since it opens to the joint piece 35 side, the said engagement piece 35 is not undercut shape also with respect to the upper wall part 31 of the said 2nd attachment seat 23 in an up-down direction.

したがって、上記第２部材３の上記第２取付座２３周辺部を成形する際、スライド型は不要である。このように、成形型３９の型構造が簡素であるため、当該成形型３９に要するコストを低減することができる。 Therefore, when the peripheral part of the second mounting seat 23 of the second member 3 is molded, a slide mold is unnecessary. Thus, since the mold structure of the mold 39 is simple, the cost required for the mold 39 can be reduced.

上記構成を備える第１部材１及び第２部材３は、図１及び図２に示すように、上記第１部材１の第１取付座８が上記第２部材３の連通孔２１から上記第２取付座２３の収容凹部２５に収容され、上記第２部材３の係合片３５の係合爪３５ａに上記第１取付座８の開口部１５の上側の周縁部が係止している。より具体的には、上記係合爪３５ａに上記第１取付座８の上壁部１７前端が引っかかる。そして、上記第１部材１のボス１９が上記第２取付座２３の切欠部３３に対向し、切欠部３３の幅よりも大径の頭部３７ａを有するタッピングスクリュー３７が上側から切欠部３３に挿通されて上記ボス１９のネジ孔１９ａにねじ込まれている。これにより、上記第２取付座２３の上壁部３１が上記タッピングスクリュー３７の頭部３７ａと上記第１部材１のボス１９によって挟持され、上記第１部材１が第２部材３に取り付けられている。 As shown in FIGS. 1 and 2, the first member 1 and the second member 3 having the above-described configuration are configured such that the first mounting seat 8 of the first member 1 is connected to the second hole 3 from the communication hole 21 of the second member 3. The upper peripheral portion of the opening 15 of the first mounting seat 8 is engaged with the engaging claw 35 a of the engaging piece 35 of the second member 3. More specifically, the front end of the upper wall portion 17 of the first mounting seat 8 is caught by the engagement claw 35a. The boss 19 of the first member 1 is opposed to the notch 33 of the second mounting seat 23, and the tapping screw 37 having a head portion 37 a having a diameter larger than the width of the notch 33 is changed from the upper side to the notch 33. It is inserted and screwed into the screw hole 19 a of the boss 19. As a result, the upper wall portion 31 of the second mounting seat 23 is sandwiched between the head 37 a of the tapping screw 37 and the boss 19 of the first member 1, and the first member 1 is attached to the second member 3. Yes.
