Description

本発明は、ドアに取り付けられた回動軸材に対して、ドア開閉操作用のハンドルを結合する回転ハンドル連結構造に関する。   The present invention relates to a rotating handle connecting structure for connecting a door opening / closing handle to a rotating shaft member attached to a door.

ドアに設けられたラッチボルトを作動させるためにドアに取り付けられた回動軸材に対し、開閉操作用のハンドルを結合するための連結構造に関しては、従来よりさまざまなものがあった。その１つとして、断面が略直角３角形状の一対の回動軸材を、ハンドルに形成した連結孔内に挿入して双方を結合した連結構造があった（例えば、特許文献１参照）。   Conventionally, there have been various connection structures for connecting a handle for opening / closing operation to a rotating shaft member attached to a door to operate a latch bolt provided on the door. As one of them, there is a connection structure in which a pair of rotating shaft members having a substantially right-angled triangular cross section are inserted into a connection hole formed in a handle and both are coupled (for example, see Patent Document 1).

これは図６に示すように、回動軸材１０１ａ、１０１ｂをハンドル１０２の断面が正方形状の連結孔１０３内に挿入した後、ハンドル１０２の外部から連結孔１０３内へと進入させた締結螺子１０４を一方の回動軸材１０１ａに螺合させるとともに、締結螺子１０４の先端部で他方の回動軸材１０１ｂの側面を押動させているものである。これにより、一対の回動軸材１０１ａ、１０１ｂは互いに引き離され、それぞれの直角を形成する２面が連結孔１０３の内周面を押圧するため、一対の回動軸材１０１ａ、１０１ｂは互いに所定の間隔を保持した状態で、ハンドル１０２に結合される。
実開平７−３２１３６号公報 As shown in FIG. 6, the fastening screws 101 a and 101 b are inserted into the connecting hole 103 having a square cross section of the handle 102 and then entered into the connecting hole 103 from the outside of the handle 102. 104 is screwed to one rotating shaft 101a, and the side surface of the other rotating shaft 101b is pushed by the tip of the fastening screw 104. Accordingly, the pair of rotating shaft members 101a and 101b are separated from each other, and the two surfaces forming the respective right angles press the inner peripheral surface of the connecting hole 103, and thus the pair of rotating shaft members 101a and 101b are predetermined to each other. In this state, the handle 102 is coupled.
Japanese Utility Model Publication No. 7-32136

しかしながら、上述した従来技術によるハンドルの連結構造は、回動軸材１０１ａ、１０１ｂの一対の直角面により形成されたエッジ部が連結孔１０３を押圧するため、連結孔１０３の隅部に応力が集中し、ハンドル１０２の亀裂等の恐れがあった。特に、昨今はドア操作者の手触り感や意匠性の向上のために、金属材料が敬遠されて合成樹脂製のハンドルを使用する場合が多く、結合時に発生した応力によるハンドルへのダメージが大きかった。
本発明は上記事情に鑑みてなされたものであり、その目的は、ハンドルへのダメージの少ない回転ハンドル連結構造を提供することにある。 However, in the above-described conventional handle connecting structure, the edge formed by the pair of right-angled surfaces of the rotating shaft members 101a and 101b presses the connecting hole 103, so that stress concentrates on the corner of the connecting hole 103. However, there was a risk of cracks in the handle 102. In particular, in recent years, in order to improve the feel and design of the door operator, metal materials are often avoided and synthetic resin handles are often used, and damage to the handles due to stress generated during bonding has been significant. .
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a rotating handle coupling structure with little damage to the handle.

本発明による回転ハンドル連結構造は、長尺状を呈し、少なくとも一端において所定の角度で向き合う一対の側面が形成された回動軸材と、把持可能な握り部および握り部と接続された結合部とにより一体に形成され、結合部には、回動軸材の一端が挿入されるために断面が略４辺形を呈するとともに、隣り合う一対の辺が回動軸材の一対の側面が成す角度と等しい角度を形成する連結孔が設けられ、連結孔は、結合部の側面において連結孔の軸中心に向けて形成された締付孔により外部と連通したハンドルと、連結孔に挿入された回動軸材の外周面と連結孔の内周面との間に介装可能なように、金属製の板材が折り曲げられて形成され、互いに離れた状態で連結孔の隣り合う一対の辺が成す角度と等しい角度を形成するように向き合う一対の平板状の押圧部と、押圧部の一端部同士を互いに接続する接続部を有し、接続部には押圧部に対してそれぞれ接続され、連結孔の残りの一対の辺が成す角度と等しい角度を形成するように向き合った一対の平板状の牽引部が形成されるとともに、一対の牽引部の間には雌螺子孔が貫通した連結プレートとを備えている。   The rotating handle coupling structure according to the present invention has a long shaft shape, a rotating shaft member formed with a pair of side surfaces facing each other at a predetermined angle at least at one end, a gripping portion that can be gripped, and a coupling portion connected to the gripping portion Since one end of the rotating shaft member is inserted into the coupling portion, the cross section has a substantially quadrilateral shape, and a pair of adjacent sides forms a pair of side surfaces of the rotating shaft member. A connecting hole that forms an angle equal to the angle is provided, and the connecting hole is inserted into the connecting hole and a handle that communicates with the outside by a tightening hole that is formed toward the axial center of the connecting hole on the side surface of the connecting portion. A metal plate is formed by being bent so that it can be interposed between the outer peripheral surface of the rotating shaft member and the inner peripheral surface of the connecting hole, and a pair of adjacent sides of the connecting hole are separated from each other. A pair facing each other to form an angle equal to the angle formed A flat pressing portion and a connecting portion that connects one end portions of the pressing portion to each other. The connecting portion is connected to the pressing portion, and an angle equal to an angle formed by the remaining pair of sides of the coupling hole. A pair of flat plate-like traction portions facing each other so as to form a plate is provided, and a connecting plate having a female screw hole is provided between the pair of traction portions.

回動軸材に対してハンドルを結合する場合、回動軸材の所定の角度で向き合う一対の側面と、連結孔の内周面であって回動軸材の一対の側面が成す角度と等しい角度を形成する隣り合う一対の面との間に、連結プレートの一対の押圧部が位置するように連結孔内に連結プレートおよび回動軸材を挿入した後、締付孔に挿通させた締結螺子を連結プレートの雌螺子孔に締め付けながら、連結プレートの内周側に突出した締結螺子の先端により回動軸材を押動することにより、回動軸材の所定の角度で向き合う一対の側面が連結プレートの押圧部を付勢して互いに拡開させ、それぞれの押圧部が連結孔の隣り合う一対の面を押圧するとともに、連結プレートの牽引部はそれぞれ押圧部と反対方向に引っ張られ連結孔の残りの一対の面を押圧する。
これにより、連結プレートの一対の押圧部および牽引部が、連結孔の表面形状に倣って弾性変形して連結孔の表面を均等に押圧するため、連結孔の表面に応力が集中することがなく、ハンドルへのダメージを低減した状態でハンドルを回動軸材に結合することができる。 When the handle is coupled to the rotating shaft, the angle between the pair of side surfaces facing the rotating shaft at a predetermined angle and the inner peripheral surface of the connecting hole and the pair of side surfaces of the rotating shaft are equal. Fastening after inserting the connecting plate and the rotating shaft material into the connecting hole so that the pair of pressing portions of the connecting plate are positioned between a pair of adjacent surfaces forming an angle, and then inserting them into the fastening hole A pair of side surfaces facing each other at a predetermined angle of the rotating shaft member by pushing the rotating shaft member with the tip of the fastening screw protruding to the inner peripheral side of the connecting plate while tightening the screw into the female screw hole of the connecting plate. Urges the pressing part of the connecting plate to expand each other, and each pressing part presses a pair of adjacent surfaces of the connecting hole, and the pulling part of the connecting plate is pulled in the opposite direction to the pressing part and connected. Press the remaining pair of surfaces of the hole.
As a result, the pair of pressing portions and the pulling portion of the connection plate are elastically deformed according to the surface shape of the connection hole to uniformly press the surface of the connection hole, so that stress is not concentrated on the surface of the connection hole. The handle can be coupled to the rotating shaft member with reduced damage to the handle.

また、本発明による回転ハンドル連結構造は、連結プレートの接続部にバーリング加工が施され、バーリング加工により形成された絞り部位に雌螺子孔が形成されている。これにより、雌螺子孔を形成するための筒状部を連結プレートのプレス工程にて同時に形成することができ、製造の容易な連結構造にすることができる。   Further, in the rotating handle coupling structure according to the present invention, the connecting portion of the coupling plate is subjected to burring processing, and a female screw hole is formed in the throttle portion formed by burring processing. Thereby, the cylindrical part for forming a female screw hole can be formed simultaneously in the press process of a connection plate, and it can be set as a connection structure easy to manufacture.

また、本発明による回転ハンドル連結構造は、回動軸材における締結螺子の先端が当接する部位には位置決め孔が形成され、締結螺子を雌螺子孔に締め付けていくことにより、締結螺子の先端が位置決め孔に嵌合する。これにより、回動軸材が締結螺子に対して位置ずれすることがなく、振動が加わる等してもハンドルと回動軸材との結合が外れることがない。   Further, in the rotating handle coupling structure according to the present invention, a positioning hole is formed at a portion where the tip of the fastening screw contacts the rotating shaft member, and the fastening screw is fastened to the female screw hole so that the tip of the fastening screw is Fits into the positioning hole. As a result, the rotating shaft member is not displaced relative to the fastening screw, and the handle and the rotating shaft member are not disconnected even when vibration is applied.

＜実施形態１＞
図１および図２に基づいて、実施形態１による回転ハンドル連結構造について説明する。回動軸材１（本発明の回動軸材に該当する）は金属あるいは合成樹脂材料等にて長尺状に形成されており、全体として角柱状を呈している（図１において、その一端部のみを示す）。回動軸材１は、ラッチボルトを作動させるためにドア（いずれも図示せず）に回転可能に取り付けられるためのものである。回動軸材１は全長にわたって軸方向に垂直な断面が変則的な５角形に形成されており、断面形状はＸ軸に関して対称となっている（図２示）。尚、上述した断面形状は、回動軸材１の少なくとも端部のみに形成されていればよい。 <Embodiment 1>
Based on FIG. 1 and FIG. 2, the rotating handle coupling structure according to the first embodiment will be described. A rotating shaft 1 (corresponding to the rotating shaft of the present invention) is formed in a long shape with a metal or a synthetic resin material, and has a prismatic shape as a whole (in FIG. 1, one end thereof). Part only). The rotating shaft 1 is for being rotatably attached to a door (none of which is shown) in order to operate a latch bolt. The rotating shaft 1 has an irregular pentagonal cross section perpendicular to the axial direction over its entire length, and the cross sectional shape is symmetric with respect to the X axis (shown in FIG. 2). In addition, the cross-sectional shape mentioned above should just be formed only in the at least edge part of the rotating shaft material 1. FIG.

回動軸材１の上述した５角形を形成する側面のうちの隣り合った一対の面である前方面１１ａ、１１ｂは、互いに直角に位置するように形成されており、前方面１１ａ、１１ｂにはそれぞれ斜面１２ａ、１２ｂがほぼ直角に接続され、斜面１２ａ、１２ｂは後面１３により連結されている。後述するように、回動軸材１とハンドル２とを結合する場合に、締結螺子４の先端が当接する部位である後面１３の中央部には、位置決め孔１４（本発明の位置決め孔に該当する）が前方面１１ａ、１１ｂの接続位置に到達するように垂直に貫通している。位置決め孔１４は内径が後述する締結螺子４の外径よりも小さく、回動軸材１の軸方向端部から所定距離だけ内方に入った位置に形成されている。一方、回動軸材１の反対側の端部においても、位置決め孔１４を含めて同様の構成が形成されている。   Front surfaces 11a and 11b, which are a pair of adjacent surfaces among the side surfaces forming the pentagon described above of the rotating shaft member 1, are formed so as to be positioned at right angles to each other, and are formed on the front surfaces 11a and 11b. Are inclined at right angles, and the inclined surfaces 12a and 12b are connected by a rear surface 13. As will be described later, a positioning hole 14 (corresponding to the positioning hole of the present invention) is formed at the center of the rear surface 13 where the tip of the fastening screw 4 abuts when the rotating shaft 1 and the handle 2 are coupled. Is vertically penetrated so as to reach the connection position of the front surfaces 11a and 11b. The positioning hole 14 has an inner diameter smaller than an outer diameter of a fastening screw 4 to be described later, and is formed at a position that enters inward from the axial end of the rotating shaft 1 by a predetermined distance. On the other hand, the same configuration including the positioning hole 14 is also formed at the opposite end of the rotating shaft 1.

ハンドル２（本発明のハンドルに該当する）は合成樹脂材料により一体に形成されており、ハンドル操作者が把持可能な握り部２１（本発明の握り部に該当する）とこれに接続された結合部２２（本発明の結合部に該当する）とにより形成されている（図１示）。結合部２２はおよそ円柱状に形成された大径部２３と、その端部に形成され大径部２３よりも小さい外径を有した小径部２４を有しており、小径部２４は本実施形態による連結構造をドアに取り付ける場合に、ドア内部に埋没する部位である。   The handle 2 (corresponding to the handle of the present invention) is integrally formed of a synthetic resin material, and a handle 21 (corresponding to the grip of the present invention) that can be gripped by the handle operator and a connection connected thereto. It is formed by the part 22 (corresponding to the joint part of the present invention) (shown in FIG. 1). The coupling portion 22 has a large diameter portion 23 formed in a columnar shape, and a small diameter portion 24 formed at an end thereof and having an outer diameter smaller than that of the large diameter portion 23. When attaching the connection structure by a form to a door, it is a site | part buried in the inside of a door.

結合部２２には、回動軸材１の一端が挿入されるために連結孔２５（本発明の連結孔に該当する）が設けられている。連結孔２５は、図１において結合部２２の下端から結合部２２の軸方向に延びており、その全長にわたり軸方向に垂直な断面がほぼ正方形を呈している（図２示）。すなわち、連結孔２５は４つの側面により形成され、隣り合った側面同士は互いに直角に位置しており、連結孔２５の隣り合う一対の側面が形成する角度は、回動軸材１の前方面１１ａ、１１ｂ同士が成す角度と等しい。   The coupling portion 22 is provided with a coupling hole 25 (corresponding to the coupling hole of the present invention) for inserting one end of the rotating shaft 1. The connecting hole 25 extends in the axial direction of the coupling portion 22 from the lower end of the coupling portion 22 in FIG. 1, and the cross section perpendicular to the axial direction has a substantially square shape over the entire length (shown in FIG. 2). That is, the connecting hole 25 is formed by four side surfaces, adjacent side surfaces are positioned at right angles to each other, and the angle formed by a pair of adjacent side surfaces of the connecting hole 25 is the front surface of the rotating shaft 1. It is equal to the angle formed by 11a and 11b.

また、結合部２２の外周面には締付孔２６（本発明の締付孔に該当する）が形成されている。締付孔２６は結合部２２の外周面から連結孔２５の軸中心に向けて延びており、連結孔２５を形成する一対の側面が直交している部位へと到達し、これにより連結孔２５は結合部２２の外部と連通されている。
一方、ハンドル２の握り部２１は平板状に形成されており、円柱状の結合部２２の軸中心から半径方向へと延びている。これにより、ハンドル操作者は握り部２１を把持して、ハンドル２を結合部２２の軸中心に回動可能となっている。 Further, a tightening hole 26 (corresponding to the tightening hole of the present invention) is formed on the outer peripheral surface of the coupling portion 22. The tightening hole 26 extends from the outer peripheral surface of the coupling portion 22 toward the axial center of the connection hole 25, and reaches a portion where a pair of side surfaces forming the connection hole 25 are orthogonal to each other. Is communicated with the outside of the coupling portion 22.
On the other hand, the grip portion 21 of the handle 2 is formed in a flat plate shape, and extends in the radial direction from the axial center of the cylindrical coupling portion 22. As a result, the handle operator can grip the grip portion 21 and rotate the handle 2 about the axis of the coupling portion 22.

連結プレート３（本発明の連結プレートに該当する）は金属製の板材をプレス成型することにより折り曲げられて形成されている。連結プレート３は、連結孔２５に挿入された回動軸材１の外周面と連結孔２５の内周面との間に介装され、回動軸材１の外周面を取り囲むことが可能なように５つの側面により形成され、図２に示すように、その軸方向に垂直な断面形状は（Ｘ軸に関して）対称となっている。   The connection plate 3 (corresponding to the connection plate of the present invention) is formed by bending a metal plate material by press molding. The connecting plate 3 is interposed between the outer peripheral surface of the rotating shaft member 1 inserted into the connecting hole 25 and the inner peripheral surface of the connecting hole 25, and can surround the outer peripheral surface of the rotating shaft member 1. As shown in FIG. 2, the cross-sectional shape perpendicular to the axial direction is symmetric (with respect to the X axis).

連結プレート３は、互いに離れた状態で直角に向き合う一対の押圧部３１ａ、３１ｂ（本発明の押圧部に該当する）と、これらの押圧部３１ａ、３１ｂの一端部同士を互いに接続する接続部３２（本発明の接続部に該当する）を有している。したがって、押圧部３１ａ、３１ｂ同士が形成する角度は、連結孔２５の隣り合った側面同士が成す角度と等しい。接続部３２には押圧部３１ａ、３１ｂに対してそれぞれ直行するように接続された一対の牽引部３３ａ、３３ｂ（本発明の牽引部に該当する）が形成されるとともに、一対の牽引部３３ａ、３３ｂの間を連結する締付面３４が設けられている。したがって、牽引部３３ａ、３３ｂ同士が形成する角度は、連結孔２５の残りの隣り合った側面同士が成す角度と等しい。   The connecting plate 3 has a pair of pressing portions 31a and 31b (corresponding to the pressing portion of the present invention) facing each other at right angles in a state of being separated from each other, and a connecting portion 32 that connects one end portions of these pressing portions 31a and 31b to each other. (Corresponding to the connecting portion of the present invention). Therefore, the angle formed by the pressing portions 31a and 31b is equal to the angle formed by the adjacent side surfaces of the connecting hole 25. The connecting portion 32 is formed with a pair of traction portions 33a and 33b (corresponding to the traction portion of the present invention) connected so as to be orthogonal to the pressing portions 31a and 31b, respectively, and a pair of traction portions 33a, A tightening surface 34 is provided to connect between 33b. Therefore, the angle formed by the traction portions 33 a and 33 b is equal to the angle formed by the remaining adjacent side surfaces of the connecting hole 25.

締付面３４の中央部にはバーリング加工が施されて、押圧部３１ａ、３１ｂ方向へと絞られた筒状部３５（本発明の絞り部位に該当する）が形成されており、筒状部３５の内周面には雌螺子３６が形成されている。雌螺子３６が形成された筒状部３５の内周面は、本発明の雌螺子孔に該当する。   A burring process is applied to the central portion of the fastening surface 34 to form a cylindrical portion 35 (corresponding to the throttle portion of the present invention) that is squeezed in the direction of the pressing portions 31a and 31b. A female screw 36 is formed on the inner peripheral surface of 35. The inner peripheral surface of the cylindrical portion 35 in which the female screw 36 is formed corresponds to the female screw hole of the present invention.

ここで、図２に示したように、連結プレート３のそれぞれの押圧部３１ａ、３１ｂの長さＡは、後述するように回動軸材１とハンドル２とを結合する場合に、押圧部３１ａ、３１ｂからハンドル２の連結孔２５の内周面に加えられる面圧を低減するためには、極力大きくすることが望ましい。しかしながら製造上の理由から、押圧部３１ａ、３１ｂと連結孔２５の内周面との間が平行でない場合、押圧部３１ａ、３１ｂの先端部から連結孔２５の内周面に対して荷重が働くことを考慮すれば、連結孔２５の内周面を形成する側面の中央部を押圧させるために、押圧部３１ａ、３１ｂの長さＡを連結孔２５の側面の幅Ｂのおよそ１／２にすることが望ましい。   Here, as shown in FIG. 2, the length A of each of the pressing portions 31 a and 31 b of the connecting plate 3 is set so that the pressing portion 31 a is connected when the rotary shaft 1 and the handle 2 are coupled as will be described later. In order to reduce the surface pressure applied from 31b to the inner peripheral surface of the connecting hole 25 of the handle 2, it is desirable to increase it as much as possible. However, for manufacturing reasons, when the pressing portions 31a and 31b and the inner peripheral surface of the connecting hole 25 are not parallel, a load acts on the inner peripheral surface of the connecting hole 25 from the tip portions of the pressing portions 31a and 31b. In view of this, in order to press the central portion of the side surface forming the inner peripheral surface of the connecting hole 25, the length A of the pressing portions 31a and 31b is set to about ½ of the width B of the side surface of the connecting hole 25. It is desirable to do.

次に、本実施形態の回転ハンドル連結構造による、回動軸材１とハンドル２との結合方法について説明する。最初に、ハンドル２の連結孔２５内に、連結プレート３を挿入していく。図２に示したように、連結プレート３は締付面３４がハンドル２の締付孔２６と対向する向きに挿入する。   Next, a method for coupling the rotating shaft 1 and the handle 2 by the rotating handle coupling structure of the present embodiment will be described. First, the connecting plate 3 is inserted into the connecting hole 25 of the handle 2. As shown in FIG. 2, the connecting plate 3 is inserted so that the fastening surface 34 faces the fastening hole 26 of the handle 2.

次に、連結孔２５内に挿入された連結プレート３の押圧部３１ａ、３１ｂの内側に回動軸材１の前方面１１ａ、１１ｂが位置するように、回動軸材１を連結プレート３内に挿入する。これにより、回動軸材１の前方面１１ａ、１１ｂと、連結孔２５の内周面であって回動軸材１の一対の前方面１１ａ、１１ｂが成す角度と等しい角度である直角を形成する隣り合う一対の面との間に、連結プレート３の押圧部３１ａ、３１ｂが位置する。   Next, the rotating shaft 1 is placed in the connecting plate 3 so that the front surfaces 11a, 11b of the rotating shaft 1 are positioned inside the pressing portions 31a, 31b of the connecting plate 3 inserted into the connecting hole 25. Insert into. Thereby, the right angle which is an angle equal to the angle which the front surfaces 11a and 11b of the rotation shaft 1 and the inner peripheral surface of the connecting hole 25 and the pair of front surfaces 11a and 11b of the rotation shaft 1 form is formed. The pressing portions 31a and 31b of the connecting plate 3 are positioned between a pair of adjacent surfaces.

次に、回動軸材１に形成された位置決め孔１４、連結プレート３に形成された雌螺子３６およびハンドル２に形成された締付孔２６を互いに位置合わせした後、締付孔２６から締結螺子４を挿入させ、連結プレート３の雌螺子３６に締め付けるとともに、連結プレート３の内周側に突出した締結螺子４の先端を回動軸材１の位置決め孔１４に嵌合させる。   Next, the positioning hole 14 formed in the rotating shaft 1, the female screw 36 formed in the connecting plate 3, and the tightening hole 26 formed in the handle 2 are aligned with each other, and then tightened from the tightening hole 26. The screw 4 is inserted and fastened to the female screw 36 of the connecting plate 3, and the tip of the fastening screw 4 protruding to the inner peripheral side of the connecting plate 3 is fitted into the positioning hole 14 of the rotating shaft member 1.

締結螺子４を連結プレート３の雌螺子３６に締め付けていくことにより、連結プレート３の内周側に突出したその先端が、回動軸材１を図２において左方に押動する。これにより、回動軸材１の前方面１１ａ、１１ｂが、連結プレート３の押圧部３１ａ、３１ｂを付勢して弾性変形させて互いに拡開させる。押圧部３１ａ、３１ｂは拡開されながら、それぞれが当接した連結孔２５の隣り合う一対の面を押圧する。それとともに、連結プレート３の接続部３２が締結螺子４の締め付けにともなう軸力により、図２において右方に引っ張られることにより、牽引部３３ａ、３３ｂは、それぞれ弾性変形して押圧部３１ａ、３１ｂと反対方向に引っ張られ、当接した連結孔２５の残りの一対の面を押圧する。これによって、ハンドル２の回動軸材１の一端への結合が完了する。   When the fastening screw 4 is fastened to the female screw 36 of the connecting plate 3, the tip projecting toward the inner peripheral side of the connecting plate 3 pushes the rotating shaft 1 leftward in FIG. 2. Thereby, the front surfaces 11a and 11b of the rotating shaft 1 urge the pressing portions 31a and 31b of the connecting plate 3 to be elastically deformed to expand each other. While the pressing portions 31a and 31b are expanded, the pressing portions 31a and 31b press a pair of adjacent surfaces of the connecting holes 25 that are in contact with each other. At the same time, the connecting portion 32 of the connecting plate 3 is pulled rightward in FIG. 2 by the axial force accompanying the tightening of the fastening screw 4, whereby the traction portions 33a and 33b are elastically deformed, respectively, and the pressing portions 31a and 31b. The other pair of surfaces of the connecting hole 25 that are in contact with and pressed against each other are pressed. This completes the coupling of the handle 2 to one end of the rotating shaft 1.

完成した回転ハンドル連結構造をドアに取り付けた後、回動軸材１の一端に結合されたハンドル２の握り部２１を操作者が把持して回動させることにより、回動軸材１が回転されてラッチボルトを作動させ、ドアの開閉操作が行われる。尚、回動軸材１の他端部においても、上述した場合と同様の方法によりハンドル２が結合され、回動軸材１の両端部に結合されたハンドル２は、ドアの両側においてそれぞれ開閉操作者の操作に供される。   After the completed rotating handle connecting structure is attached to the door, the rotating shaft 1 is rotated by the operator gripping and rotating the grip portion 21 of the handle 2 coupled to one end of the rotating shaft 1. Then, the latch bolt is actuated to open and close the door. Note that the handle 2 is coupled to the other end of the rotating shaft 1 in the same manner as described above, and the handles 2 coupled to both ends of the rotating shaft 1 are opened and closed on both sides of the door. It is used for the operation of the operator.

Thereby, the cylindrical part 35 for forming the internal thread 36 can be simultaneously formed in the press process of the connection plate 3, and it can be set as a connection structure easy to manufacture.

また、本実施形態によれば、回動軸材１における締結螺子４の先端が当接する部位には位置決め孔１４が形成され、締結螺子４を雌螺子３６に締め付けていくことにより、締結螺子４の先端が位置決め孔１４に嵌合する。これにより、回動軸材１が締結螺子４に対して位置ずれすることがなく、振動が加わる等してもハンドル２と回動軸材１との結合が外れることがない。   Further, according to the present embodiment, the positioning hole 14 is formed at the portion of the rotating shaft 1 where the tip of the fastening screw 4 contacts, and the fastening screw 4 is fastened to the female screw 36.

According to this embodiment, the rotating shaft 6 is formed in a substantially triangular column shape. In other words, the rotary shaft 6 has a cross section perpendicular to the axial direction over the entire length and is formed in a substantially isosceles triangle. In the rotating shaft 6, the front surfaces 61 a and 61 b that are adjacent pairs among the side surfaces forming the right isosceles triangle are formed so as to be positioned at right angles to each other. As in the case of the first embodiment, the front surfaces 61 a and 61 b are for urging the pressing portions 31 a and 31 b of the connecting plate 3, and these are connected by the rear surface 62. Further, a positioning hole 63 penetrates vertically through the center of the rear surface 62 so as to reach the connection position of the front surfaces 61a and 61b. Since other configurations are the same as those in the first embodiment, description thereof is omitted.

＜実施形態４＞
図５に基づき、実施形態４による回転ハンドル連結構造について説明する。本実施形態によれば、回動軸材７は変則的な６角柱状に形成されている。回動軸材７の図５における左方には平坦面７１が形成され、この平坦面７１の両端部には一対の前方面７２ａ、７２ｂが互いに直角に位置するように接続されている。実施形態１の場合と同様に、前方面７２ａ、７２ｂは連結プレート３の押圧部３１ａ、３１ｂを付勢するためのものである。 <Embodiment 4>

前方面７２ａ、７２ｂにはそれぞれ斜面７３ａ、７３ｂがほぼ直角に接続され、斜面７３ａ、７３ｂは後面７４により連結されている。また後面７４の中央部には、位置決め孔７５が形成されている。位置決め孔７５は、実施形態１の場合とは異なり平坦面７１側へ貫通してはいない。このように、位置決め孔７５は有底であってもよいし、上述した実施形態１乃至３に示したように、回動軸材１、６に貫通していてもよい。その他の構成については、実施形態１の場合と同様であるため説明は省略する。
本実施形態によれば、回動軸材７において位置決め孔７５が貫通していないため、その形成工程の時間を短縮することができる。 Slopes 73 a and 73 b are connected to the front surfaces 72 a and 72 b at substantially right angles, respectively, and the slopes 73 a and 73 b are connected by a rear surface 74. A positioning hole 75 is formed at the center of the rear surface 74. Unlike the case of the first embodiment, the positioning hole 75 does not penetrate to the flat surface 71 side.
