Description

この発明は、ドアに回動自在にハンドルを取り付ける構造体に関するものである。   The present invention relates to a structure for attaching a handle to a door so as to be rotatable.

下記特許文献１には、図６に示すように、ドア６のラッチ機構７１を操作するハンドルの取付構造体が記載されている。この取付構造体は、ドア６の一方の外側面に配置される第１台座１と、ドアの他方の外側面に配置される第２台座２と、第１台座１と第２台座２とを連結するビス３と、図示していない一対のドア用ハンドルとを備え、第１台座１は、円盤状の台座本体１１と、これに装着される２本のボス４とから構成されている。   Patent Document 1 below describes a handle attachment structure for operating a latch mechanism 71 of a door 6 as shown in FIG. The mounting structure includes a first pedestal 1 disposed on one outer surface of the door 6, a second pedestal 2 disposed on the other outer surface of the door, and the first pedestal 1 and the second pedestal 2. The first pedestal 1 includes a disk-shaped pedestal main body 11 and two bosses 4 attached to the pedestal 3. The first pedestal 1 includes a connecting screw 3 and a pair of door handles (not shown).

台座本体１１には、ドア用ハンドルの回転軸が挿通されるハンドル取付穴１２が中央に設けられ、その両側に角型の座ぐりを施したボス取付穴１３が設けられている。   The pedestal main body 11 is provided with a handle attachment hole 12 through which the rotation shaft of the door handle is inserted, and boss attachment holes 13 with square counterbore on both sides thereof.

ボス４は、円筒部の基部側に角型の頭部を有する形状であり、円筒部の先端から基部側へかけて穿設されたビス螺合用ねじ穴４４の内周面に雌ねじが形成されている。また、ボス４の円筒部には、その先端から基部側へかけて、ビス螺合用ねじ穴４４の雌ねじの長さを超える長さのスリット４３が形成されている。   The boss 4 has a shape having a square head on the base side of the cylindrical portion, and a female screw is formed on the inner peripheral surface of a screw threading screw hole 44 drilled from the tip of the cylindrical portion to the base side. ing. Further, a slit 43 having a length exceeding the length of the female screw of the screw threading screw hole 44 is formed in the cylindrical portion of the boss 4 from the tip to the base side.

また、円盤状の第２台座２には、ドア用ハンドルの回転軸が挿通されるハンドル取付穴２１が中央に設けられ、その両側にビス挿通穴２２が設けられている。   In addition, the disc-shaped second pedestal 2 is provided with a handle attachment hole 21 through which the rotation shaft of the door handle is inserted, and screw insertion holes 22 on both sides thereof.

この取付構造体において、第１台座１と第２台座２とをドア６に固定する際には、ボス４を円筒部の先端から台座本体１１の外面側からボス取付穴１３に挿通し、頭部でボス取付穴１３から抜け止めした状態で、ボス４の円筒部をドア６の内部に差し込む。   In this mounting structure, when the first pedestal 1 and the second pedestal 2 are fixed to the door 6, the boss 4 is inserted from the tip of the cylindrical portion into the boss mounting hole 13 from the outer surface side of the pedestal main body 11, The cylindrical portion of the boss 4 is inserted into the door 6 in a state where the boss 4 is prevented from being detached from the boss mounting hole 13.

そして、ビス３を、第２台座２のビス挿通穴２２を介してボス４のビス螺合用ねじ穴４４にねじ込み、ドライバーＡで締め付けて、第１台座１と第２台座２とを連結した状態でドア６の所定の位置に固定する。   Then, the screw 3 is screwed into the screw screwing screw hole 44 of the boss 4 through the screw insertion hole 22 of the second pedestal 2, and is tightened with the driver A to connect the first pedestal 1 and the second pedestal 2. To fix the door 6 at a predetermined position.

このとき、作業者が第１台座１と第２台座２とを確実に固定しようとして、ビス３を締め付けすぎても、ビス３とビス螺合用ねじ穴４４との噛み合いが外れ、ボス４のスリット４３が開いてビス３が空転し、必要以上のトルクが逃がされる。これにより、ドア６の凹みなどの変形を防止することが意図されている。   At this time, even if the operator tries to securely fix the first pedestal 1 and the second pedestal 2 and the screw 3 is tightened too much, the screw 3 is disengaged from the screw screw hole 44 and the boss 4 is slit. 43 opens and the screw 3 runs idle, and more torque than necessary is released. This is intended to prevent deformation of the door 6 such as a dent.

特許第４４６３８２９号公報Japanese Patent No. 4446329

しかしながら、上記のようなドア用ハンドルの取付構造体では、ビス３を締め付けすぎた状態において、スリット４３の開きがボス４の円筒部の基部側で小さくなることから、この部分でビス３とビス螺合用ねじ穴４４との噛み合いが外れにくく、ビス３のねじ込みが進行し、ドア６の凹みなどの変形を確実に防止できない恐れがある。   However, in the door handle mounting structure as described above, when the screw 3 is tightened too much, the opening of the slit 43 becomes smaller on the base side of the cylindrical portion of the boss 4. There is a possibility that the engagement with the screw hole 44 for screwing is difficult to disengage, screwing of the screw 3 proceeds, and deformation such as a recess of the door 6 cannot be reliably prevented.

そこで、この発明は、ドアへのハンドルの取り付けに際し、ビスを締め付けすぎても、ドアの凹みなどの変形を確実に防止できるようにすることを課題とする。   Accordingly, an object of the present invention is to reliably prevent deformation of a recess or the like of a door even if a screw is tightened excessively when the handle is attached to the door.

上記課題を解決するため、この発明は、ドアの一方の外側面に配置される第１台座と、ドアの他方の外側面に配置される第２台座と、第１台座と第２台座とを連結するビスと、一対のドア用ハンドルとを備え、前記第１台座には、ドア用ハンドルの回転軸が挿通されるハンドル取付穴とボスとを設け、前記ボスには、先端から基部側へビス螺合用ねじ穴を穿設し、前記第２台座には、ドア用ハンドルの回転軸が挿通されるハンドル取付穴とビス挿通穴とを設け、前記ビスを、前記第２台座のビス挿通穴を介してボスのビス螺合用ねじ穴にねじ込むドア用ハンドルの取付構造体において、前記ボスは、弾性変形可能なものとし、ボスの周壁の対向する内面には、リブをボスの軸方向に延びるように突設し、前記ビス螺合用ねじ穴は、対向するリブの内面に雌ねじが形成され、それ以外の部分でボスの周壁の内面とビスとの間に空間が確保されるものとしたのである。   In order to solve the above problems, the present invention includes a first pedestal disposed on one outer surface of a door, a second pedestal disposed on the other outer surface of the door, and a first pedestal and a second pedestal. The first pedestal is provided with a handle mounting hole and a boss through which the rotation shaft of the door handle is inserted, and the boss is provided from the tip to the base side. A screw screw hole is drilled, and the second pedestal is provided with a handle mounting hole and a screw insertion hole through which the rotation shaft of the door handle is inserted, and the screw is inserted into the screw insertion hole of the second pedestal. In the door handle mounting structure that is screwed into the screw threading screw hole of the boss through the boss, the boss is elastically deformable, and ribs extend in the axial direction of the boss on the opposing inner surface of the peripheral wall of the boss. The screw threaded screw holes are opposed to each other. Is internally threaded on the inner surface of the formation, it is the space is assumed to be secured between the inner surface and the screw boss of the peripheral wall at the other portions.

このドア用ハンドルの取付構造体では、ビスを締め付けすぎると、締付力にボス側が負けて、ビスの外周とリブの内周のねじ山同士が突き合わされる状態となり、リブが互いに離反する方向へ押され、ビスがねじ込まれた部分の全長に亘ってボスが均一に変形することで、ねじの噛み合いが外れ、ビスが空転して、必要以上のトルクが逃がされる。   In this door handle mounting structure, if the screw is tightened too much, the boss side loses the tightening force, and the screw threads on the outer periphery of the screw and the inner periphery of the rib are in contact with each other, and the ribs are separated from each other. When the boss is uniformly deformed over the entire length of the portion into which the screw is screwed, the screw is disengaged, the screw is idled, and more torque than necessary is released.

このとき、ねじの噛み合いが外れる音や振動が生じるので、作業者は締め付け過ぎたことを把握することができ、その時点で締付動作を止めることにより、ドアの凹むような変形を確実に防止することができる。   At this time, since the noise and vibration of the disengagement of the screw are generated, the operator can grasp that the screw has been tightened too much, and by stopping the tightening operation at that time, it is possible to reliably prevent the door from being deformed. can do.

以下、この発明の実施形態を添付図面に基づいて説明する。なお、ここで使用する符号は、上記特許文献１において対応する部分に付された符号と同一のものとする。   Embodiments of the present invention will be described below with reference to the accompanying drawings. In addition, let the code | symbol used here be the same as the code | symbol attached | subjected to the corresponding part in the said patent document 1. FIG.

この取付構造体は、図１に示すように、ドア６の一方の外側面に配置される第１台座１と、ドア６の他方の外側面に配置される第２台座２と、第１台座１と第２台座２とを連結するビス３と、ドア６の彫り込み部分に収納されたラッチ機構７１を操作する一対のドア用ハンドル８とから構成されている。   As shown in FIG. 1, the mounting structure includes a first pedestal 1 disposed on one outer surface of the door 6, a second pedestal 2 disposed on the other outer surface of the door 6, and a first pedestal. And a pair of door handles 8 for operating a latch mechanism 71 housed in a carved portion of the door 6.

第１台座１は、図２に示すように、円盤状部分の中央部にドア用ハンドル８の回転軸が挿通されるハンドル取付穴１２を設け、その両側に２本のボス４を円盤状部分と一体に突設したものとされている。   As shown in FIG. 2, the first pedestal 1 is provided with a handle mounting hole 12 through which the rotating shaft of the door handle 8 is inserted at the center of the disk-shaped portion, and two bosses 4 are disposed on both sides thereof. It is supposed to project in one piece.

ボス４は、先端から基部側へビス螺合用ねじ穴４４を穿設した楕円筒状であり、弾性変形可能なものとされている。そして、ボス４には、周壁の短軸方向で対向する内面にリブ４８がボス４の軸方向に延びるように突設されている。   The boss 4 has an elliptical cylindrical shape with a screw threading screw hole 44 drilled from the distal end to the base side, and is elastically deformable. The boss 4 is provided with a rib 48 projecting from the inner surface of the peripheral wall facing in the short axis direction so as to extend in the axial direction of the boss 4.

ビス螺合用ねじ穴４４は、対向するリブ４８の内面に雌ねじが形成され、図５（ａ）に示すように、ビス３をねじ込んだとき、周壁の長軸方向の両側内面とビス３との間に空間が確保されるようになっている。   The screw threading screw hole 44 has a female screw formed on the inner surface of the opposing rib 48, and when the screw 3 is screwed in as shown in FIG. Space is secured between them.

また、図１に示すように、第２台座２は、円盤状であり、中央部にドア用ハンドル８の回転軸が挿通されるハンドル取付穴２１を設け、その両側にビス挿通穴２２を設けたものとされている。   As shown in FIG. 1, the second pedestal 2 has a disc shape, and is provided with a handle attachment hole 21 through which the rotation shaft of the door handle 8 is inserted at the center, and screw insertion holes 22 on both sides thereof. It is said that

上記のような取付構造体の施工作業においては、まず、図１及び図３に示すように、第１台座１及び第２台座２をドア６の両側からあてがい、図４（ａ）及び図５（ａ）に示すように、第２台座２のビス挿通穴２２を介してボス４のビス螺合用ねじ穴４４にビス３を挿入し、ビス３の外周の雄ねじとリブ４８の内面の雌ねじとを螺合させ、ドライバーＡで締め付ける。この状態では、ビス３の外周の雄ねじとリブ４８の内面の雌ねじとが噛み合っており、ボス４は、断面形状が楕円形状のままとなっている。   In the construction work of the mounting structure as described above, first, as shown in FIGS. 1 and 3, the first pedestal 1 and the second pedestal 2 are applied from both sides of the door 6, and FIGS. 4 (a) and 5. As shown in (a), the screw 3 is inserted into the screw threading screw hole 44 of the boss 4 through the screw insertion hole 22 of the second pedestal 2, and the male screw on the outer periphery of the screw 3 and the female screw on the inner surface of the rib 48 are And tighten with screwdriver A. In this state, the male screw on the outer periphery of the screw 3 and the female screw on the inner surface of the rib 48 are engaged with each other, and the cross-sectional shape of the boss 4 remains elliptical.

そして、締め付けが進行し、ビス３を締め付け過ぎると、締付力にボス４側が負けて、図４（ｂ）及び図５（ｂ）に示すように、ビス３の外周の雄ねじとリブ４８の内面の雌ねじの山同士が突き合わされる状態となり、リブ４８が互いに離反する方向へ押され、ボス４が短軸方向へ拡径するように変形することで、ねじの噛み合いが外れる。   Then, when the tightening proceeds and the screw 3 is tightened too much, the boss 4 side loses the tightening force, and as shown in FIGS. 4 (b) and 5 (b), the male screw on the outer periphery of the screw 3 and the rib 48 The threads of the inner female threads are brought into contact with each other, the ribs 48 are pushed away from each other, and the boss 4 is deformed so as to expand in the short axis direction, thereby disengaging the screws.

その後、ボス４が弾性により復元し、ねじの噛み合いが一山戻り、更に締め付ければ、前記同様に、締付力にボス４側が負けて短軸方向へ拡径するように変形することで、ねじの噛み合いが外れ、次いでボス４の弾性でねじの噛み合いが一山戻り、図４（ａ）及び図５（ａ）に示す状態に戻って固定される。   After that, the boss 4 is restored by elasticity, and the engagement of the screw returns to the end, and if further tightened, similarly to the above, by deforming the boss 4 side to lose the tightening force and expanding in the short axis direction, The engagement of the screw is disengaged, and then the engagement of the screw is returned by the elasticity of the boss 4, returning to the state shown in FIGS. 4A and 5A and being fixed.

すなわち、締付け力が一定以上になると、ボス４が短軸方向へ拡径するように変形することで、ビス３を空転させ、必要以上のトルクを逃がすことになる。このとき、ねじの噛み合いが外れる音や振動が生じるので、作業者は締め付け過ぎたことを把握することができ、その時点で締付動作を止めることにより、ドア６の凹むような変形を確実に防止することができる。   In other words, when the tightening force exceeds a certain value, the boss 4 is deformed so as to expand in the short axis direction, causing the screw 3 to idle, thereby releasing excessive torque. At this time, since the noise and vibration of the disengagement of the screw are generated, the operator can grasp that the screw has been tightened too much, and by stopping the tightening operation at that time, the door 6 can be reliably deformed. Can be prevented.

このようにビス３を適度な締付力で締め付けると、図３に示すように、第１台座１と第２台座２とを連結した状態で、ドア６にしっかりと固定することができる。   When the screws 3 are tightened with an appropriate tightening force, the first pedestal 1 and the second pedestal 2 can be firmly fixed to the door 6 as shown in FIG.

なお、上記実施形態では、第１台座１として、円盤状部分と２本のボス４とが一体となったものを例示したが、ボス４は、上記特許文献１に記載された取付構造体のように、円盤状部分と別体のものとしてもよい。また、ボス４の本数は特に限定されない。   In the above embodiment, the first pedestal 1 is exemplified by a disc-shaped portion and two bosses 4 integrated with each other. However, the boss 4 is an attachment structure described in Patent Document 1. Thus, it is good also as a thing different from a disk shaped part. Further, the number of bosses 4 is not particularly limited.

また、ボス４が楕円筒状のものを例示したが、ボス４は、真円筒状や角筒状のものであっても、対向するリブ４８以外の部分で、ボス４の周壁の内面とビス３との間に空間が確保されるものであれば、同様の機能を実現することができる。   Moreover, although the boss 4 has been illustrated as having an elliptical cylindrical shape, the boss 4 may be a true cylindrical shape or a square cylindrical shape, but may be a portion other than the opposing rib 48 and the inner surface of the peripheral wall of the boss 4 and the screw. If a space is ensured between 3 and 3, the same function can be realized.
