Regarding the mounting handle.

従来、この種の扉用ハンドルを扉パネルに取り付ける場合、扉パネルに扉用ハンドルのハンドルケースの取付用開口を形成するとともに、その両端部の近接した部位にねじ孔や透孔を穿設し、当該取付用開口にハンドルケースをその背面側から埋め込んだ後、扉パネルの正面側から、ビスをハンドルケ－スの透孔より扉パネルのねじ孔にねじ込むか、扉パネルの背面側から、ビスを扉パネルの透孔よりハンドルケ－スのねじ孔にねじ込むことによって、扉パネルに取り付けている。また、このような扉用ハンドルの取り付けでは、扉パネルにハンドルケ－スの取付用開口と、この開口の両端部に近接してねじ孔や透孔を設ける必要があり、このため孔開け加工をしなければならい上、ビス止めの際に扉パネルの正面側から扉用ハンドルを取付位置に押えていなければならないなど、取付作業の能率が悪いことから、ハンドルケースの正面端部に外周縁が扉パネルの正面に当接する正面板を設け、この正面板の背面側に固定用のブロックをねじにより取り付けて、扉用ハンドルを、ケースの正面板と固定用のブロックとの間に扉パネルの取付用開口の縁部を挟み込んでねじの締め込みにより固定するようにしたものも一般に使用されている。このようにこの種の扉用ハンドルの扉パネルへの取り付けでは、ねじを用いた取り付け形式が主流になっている。このような扉用ハンドル及びその取り付け形式が、特許文献１などに記載されている。 Conventionally, when this type of door handle is attached to a door panel, an opening for attaching the handle case of the door handle is formed in the door panel, and screw holes or through holes are drilled in adjacent portions of both ends of the opening. , After embedding the handle case into the mounting opening from the back side, screw the screw into the screw hole of the door panel from the through hole of the handle case from the front side of the door panel, or insert the screw from the back side of the door panel. is attached to the door panel by screwing it into the screw hole of the handle case through the through hole of the door panel. In addition, when installing such a door handle, it is necessary to provide an opening for attaching the handle case in the door panel and screw holes or through holes near both ends of this opening. In addition, the door handle must be pressed to the mounting position from the front side of the door panel when screwing, which makes the installation work inefficient. A front plate is provided in contact with the front of the door panel, a fixing block is attached to the back side of this front plate with screws, and the door handle is placed between the front plate of the case and the fixing block on the door panel. It is also commonly used to clamp the edge of the mounting opening and fix it by tightening a screw. In this way, the mounting method using screws has become mainstream in mounting this type of door handle to the door panel. Such a door handle and its mounting format are described in Patent Document 1 and the like.

In this case, as shown in FIG. 3, each case hook 15 is provided with a shaft insertion portion 140 as a rotation center C1 between both side portions 15b and 15c on one end portion 15a side serving as a shaft support side. The other end 15f is formed in an arc shape with the center of the circle on the one end 15a side of the rotation center C1 and at a position closer to the inner surface 15e on the side opposite to the outer surface 15d. Further, each case hook 15 has an outer surface 15 d formed substantially parallel to each surface forming the peripheral surface 12 of the handle case 1 . One end portion 15a, that is, between one end of the outer surface 15d and one end of the inner surface 15e is formed in a protruded shape having a substantially V-shaped cross section, and one surface continuous with the outer surface 15d is formed into a predetermined arc-shaped surface. The other surface continuous with 15e is formed as an inclined surface with a predetermined angle. The other surface that is continuous with the inner surface 15e is formed at a predetermined angle with the one surface that is continuous with the outer surface 15d, forming a stopper 151 that can be engaged with the bottom of the case hook mounting recess 13. , the collision engagement between the stopper 151 and the bottom of the case hook mounting recess 13 causes the case hooks 15 to rotate excessively in the projecting direction from the case hook mounting recesses 13, i.e., the case hooks of the case hooks 15 Projection from the mounting recess 13 (see FIG. 2) is restricted. Then, the inner surface 15e is formed symmetrically with the outer surface 15d so as to be parallel to the outer surface 15d or directed in a direction that is slightly wider than parallel, in this case, in a direction that is slightly wider than parallel. Here, the outer surface 15d and the inner surface 15e of each case hook 15 are rectangular planes, and the left and right side portions 15b and 15c are rectangular planes narrower than the width of the outer surface 15d and the inner surface 15e. 15a has a substantially V-shaped cross section. In this case, one surface continuous with the outer surface 15d is a predetermined arc-shaped surface, and the other surface continuous with the inner surface 15e is an inclined surface (stopper 151) with a predetermined angle. , and the other end 15f is a quadrangle narrower than the outer surface 15d and the inner surface 15e and has an arcuate cross section. With such a shape of the case hook 15, it can be formed in a small size according to the case hook mounting recess 13 formed in the limited space of the peripheral surface 12 of the handle case 1 and attached to the case hook mounting recess 13.
As shown in FIG. 2, the upper and lower case hooks 15 are inserted into the case hook mounting recesses 13 of the upper surface portion 1b and the lower surface portion 1e. The shaft 16 inserted between the shaft insertion portion 150 of the handle case 1, in this case, is pivotally supported via a spring pin made of stainless steel, and each locking claw 15C extends from each case hook mounting recess 13 to the peripheral surface of the handle case 1. The left and right case hooks 15 are mounted in the case hook mounting recesses 13 of the left and right side surfaces 1c and 1d, and the upper and lower bearings 14 of the upper and lower bearings 14 are installed. A shaft 16, in this case a spring pin made of stainless steel, is inserted between the groove-shaped shaft insertion portion 141 and the shaft insertion portion 150 of each case hook 15, and the hook holding plate 132 is screwed to the rear portion 1a of the handle case 1. By being stopped, each locking claw 15C is axially supported via each spring pin held by this hook holding plate 132, and each locking claw 15C extends from each case hook mounting recess 13 to the left and right sides forming the peripheral surface 12 of the handle case 1. It is arranged so that it can appear and disappear outside the side parts 1c and 1d.
In this case, since coil springs (hereinafter referred to as coil springs 17) are employed for the plurality of spring members 17, as shown in FIG. ) A cylindrical hole 152 is formed, and each coil spring 17 has one end held in the hole 152 of each case hook 15 and the other end held at the bottom of each case hook mounting recess 13, so that each case hook 15 and each It is interposed between the case hook mounting recess 13 and the case hook mounting recess 13 .
Before or after the handle case 1 is passed through the mounting opening of the door panel together with the case hooks 15, the locking claws 15C of the case hooks 15 are inserted into the respective case hook mounting recesses. When protruding from each surface forming the peripheral surface 12 of the handle case 1 from 13, each coil spring 17 can be deformed and guided in an arcuate shape convex toward the flange 11 side. and a part of the inner peripheral surface of the hole 152 on the side of one end 15a of the case hook 15 is inserted between the handle case 1 and the case hook 15 into the mounting opening. When the locking claws 15C of the case hooks 15 are inserted into the case hook mounting recesses 13, the coil springs 17 can be deformed and guided in a convex arc shape to the opposite side of the flange 11 from the deep side of the hole 152. It is formed with an inclination of a predetermined angle that gradually increases in diameter toward the opening side.

複数のばね部材１７は、既述のとおり、コイルスプリング１７が採用され、各ケースフック１５と各ケースフック取付凹部１３との間に介装され、各係止爪１５Ｃを常態として各ケースフック取付凹部１３からハンドルケース１の周面１２をなす各面の外側へ突出可能に回動付勢する。

The handle case 1 is pivotally biased so as to protrude from the concave portion 13 to the outside of each surface forming the peripheral surface 12 of the handle case 1 .
In this case, each coil spring 17 has one end attached to the spring bearing portion at the bottom of each case hook mounting recess 13, and the other end attached to the spring bearing portion at the bottom of the hole 152 of each case hook 15. It is interposed between the hook 15 and each of the case hook mounting recesses 13, and rotates so as to be able to protrude from each of the case hook mounting recesses 13 to the outside of each surface forming the peripheral surface 12 of the handle case 1 with the respective locking claws 15C in the normal state. Then, as described above, the stopper 151 of each case hook 15 and the bottom portion of each case hook mounting recess 13 collide with each other, causing each case hook 15 to protrude from each case hook mounting recess 13. Excessive turning to the right, that is, projection of each case hook 15 from each case hook mounting recess 13 is restricted.

このようにして扉用ハンドルの扉パネルへの取り付けに当たり、ハンドルケース１を扉パネルの取付用開口に扉パネルの正面側から背面側へ挿入するとともに、ハンドルケース１の周面１２の各ケースフック１５を取付用開口の縁部で押圧して各ケースフック取付凹部１３に没入させながら取付用開口を扉パネルの正面側から背面側へ通し、扉パネルの背面側で各ケースフック１５を各ケースフック取付凹部１３からハンドルケース１の周面１２をなす各面の外側へ突出させて、扉パネルの正面側でフランジ１１を取付用開口の縁部周囲に圧接させるとともに、扉パネルの背面側で各ケースフック１５の各係止爪１５Ｃを取付用開口の縁部又は縁部周囲に係止させて、扉用ハンドルを扉パネルにワンタッチで取り付けるようになっている。 In attaching the door handle to the door panel in this way, the handle case 1 is inserted into the attachment opening of the door panel from the front side to the back side of the door panel, and each case hook on the peripheral surface 12 of the handle case 1 is inserted. 15 is pressed by the edge of the mounting opening and inserted into each case hook mounting recess 13, the mounting opening is passed from the front side to the back side of the door panel, and each case hook 15 is attached to each case on the back side of the door panel. The flange 11 is protruded from the hook mounting recess 13 to the outside of each surface forming the peripheral surface 12 of the handle case 1, and the flange 11 is pressed against the periphery of the mounting opening on the front side of the door panel, and on the back side of the door panel. The locking claws 15C of the case hooks 15 are locked to the edge of the mounting opening or around the edge so that the door handle can be attached to the door panel with one touch.

図７にこのハンドルＨの扉パネルＰに対する取り付け方法を示している。
ここで、扉パネルＰには予め所定の位置にハンドルＨの取付用開口Ｐ０をハンドルケース１が嵌挿可能に縦に長い長方形状に形成してある。この場合、扉パネルＰに従来のようなねじ穴や透孔は、不要のため、設けていない。
なお、ハンドルＨは、扉パネルＰに取り付ける前の通常の状態では、ハンドルケース周面１２の各ケースフック１５は各ケースフック１５と各ケースフック取付凹部１３との間のコイルスプリング１７により外側方向に回動付勢されて、各ケースフック１５の係止爪１５Ｃが各ケースフック取付凹部１３からハンドルケース周面１２の各面の外側へ弾性的に突出され、また、各ケースフック１５の一方の端部１５ａの内面１５ｅ側に設けたストッパー１５１（図３参照）と各ケースフック取付凹部１３の底部との衝接係合により、各ケースフック１５の各ケースフック取付凹部１３からの過度の飛び出しが防止される。 FIG. 7 shows how the handle H is attached to the door panel P. As shown in FIG.
Here, in the door panel P, an opening P0 for mounting the handle H is formed in a vertically long rectangular shape at a predetermined position so that the handle case 1 can be inserted thereinto. In this case, the door panel P is not provided with conventional screw holes or through holes because they are unnecessary.
In a normal state before the handle H is attached to the door panel P, the case hooks 15 on the handle case peripheral surface 12 are outwardly pushed by the coil springs 17 between the case hooks 15 and the case hook mounting recesses 13 . , the engaging claws 15C of the case hooks 15 are elastically protruded from the respective case hook mounting recesses 13 to the outside of the respective surfaces of the handle case peripheral surface 12, and one side of each case hook 15 The stopper 151 (see FIG. 3) provided on the inner surface 15e side of the end portion 15a of the case hook 15 and the bottom of each case hook mounting recess 13 prevent excessive force from the case hook mounting recess 13 from each case hook 15. Jumping out is prevented.

図７において、ハンドルＨを扉パネルＰへ取り付けるに当たり、まず、ハンドルケース１のフランジ１１の背面にケースパッキン１１０を被着し、ハンドルケース１を縦向きにして扉パネルＰの取付用開口Ｐ０の向きに合せ、ハンドルケース１を各ケースフック１５とともに扉パネルＰの取付用開口Ｐ０に差し込み、押し込む（ワンプッシュする）。
このようにすると、ハンドルケース１の周面１２は、つまり、ハンドルケース１の上面部１ｂ、下面部１ｅ、左右両側面部１ｃ、１ｄの各面が背面部１ａ側の一端から中間へ、中間から正面部側の他端へ、扉パネルＰの取付用開口Ｐ０の短辺方向及び長辺方向の各縁部を摺動しつつ、扉パネルＰの取付用開口Ｐ０を通過する。この間、ハンドルケース１の上面部１ａ、下面部１ｅ、左右両側面部１ｃ、１ｄの各面から外側に突出される各ケースフック１５の各係止爪１５Ｃが扉パネルＰの取付用開口Ｐ０の短辺方向及び長辺方向の各縁部に接触して押圧され、各係止爪１５Ｃが各ケースフック１５と各ケースフック取付凹部１３との間のコイルスプリング１７の付勢力に抗して（コイルスプリング１７を圧縮しながら）ハンドルケース１の上面部１ｂ、下面部１ｅ、左右両側面部１ｃ、１ｄの各ケースフック取付凹部１３に向けて回動し、各ケースフック取付凹部１３内に没入されていく。そして（ハンドルケース１が扉パネルＰの取付用開口Ｐ０に押し込まれた瞬間）、各ケースフック１５の各係止爪１５Ｃが完全に各ケースフック取付凹部１３内に没入されて、ハンドルケース１が扉パネルＰの取付用開口Ｐ０を完全に通過し、ハンドルケース１の正面開口１０の全周縁部周囲のフランジ１１がケースパッキン１１０を介して扉パネルＰの正面側で取付用開口Ｐ０の全周縁部の周囲に当接するとともに、各ケースフック取付凹部１３内の各ケースフック１５は扉パネルＰの取付用開口Ｐ０の通り抜けにより扉パネルＰの背面側で各ケースフック１５と各ケースフック取付凹部１３との間のコイルスプリング１７の付勢力（コイルスプリング１７の弾性復帰）により各ケースフック１５の各係止爪１５Ｃがハンドルケース１の上面部１ｂ、下面部１ｅ、左右両側面部１ｃ、１ｄの各ケースフック取付凹部１３から外側方向へ回動し、各ケースフック取付凹部１３から外側に突出されて、扉パネルＰの取付用開口Ｐ０の短辺方向及び長辺方向の各縁部に弾性係止される。ここで、このハンドルＨは、図３に示したように、各ケースフック１５の回動中心Ｃ１が各ケースフック１５の一方の端部１５ａ側でかつ外面１５ｄと内面１５ｅとの間の少し内面１５ｅ寄りに設けられ、各ケースフック１５の他方の端部１５ｆが円の中心を各ケースフック１５の回動中心Ｃ１よりも各ケースフック１５の一方の端部１５ａに近くかつ内面１５ｅ寄りの位置におく円弧状に形成されたことで、各ケースフック１５は、各係止爪１５Ｃの外側への回動とともに各係止爪１５Ｃの円弧状の部分が扉パネルＰの取付用開口Ｐ０の縁部に向けて迫り出して、取付用開口Ｐ０の短辺方向及び長辺方向の各縁部に食い込み、これにより、ハンドルケース１の正面側のフランジ１１は（防水パッキン１１０を介して）扉パネルＰの正面側で取付用開口Ｐ０の全周縁部の周囲に引き寄せられて圧接され、ハンドルＨが扉パネルＰに強固に取り付け固定される。このようにしてハンドルＨを扉パネルＰにワンタッチで簡易にかつ確実に固定することができる。 In FIG. 7, when the handle H is attached to the door panel P, first, the case packing 110 is attached to the rear surface of the flange 11 of the handle case 1, and the handle case 1 is oriented vertically so that the opening P0 for attachment of the door panel P is opened. The handle case 1 is inserted into the mounting opening P0 of the door panel P together with the case hooks 15 and pushed in (one push).
In this way, the peripheral surface 12 of the handle case 1, that is, the upper surface portion 1b, the lower surface portion 1e, and the left and right side surfaces 1c and 1d of the handle case 1 extend from one end of the back surface portion 1a to the middle and from the middle to the middle. It passes through the mounting opening P0 of the door panel P while sliding along the short and long side edges of the mounting opening P0 of the door panel P to the other end on the front side. During this time, the engaging claws 15C of the case hooks 15 projecting outward from the upper surface 1a, the lower surface 1e, the left and right side surfaces 1c, and 1d of the handle case 1 are engaged with the short sides of the door panel P mounting opening P0. Each locking claw 15C is pressed against the urging force of the coil spring 17 between each case hook 15 and each case hook mounting recess 13 (coil While compressing the spring 17, the upper surface portion 1b, the lower surface portion 1e, the left and right side surfaces 1c and 1d of the handle case 1 are rotated toward the case hook mounting recesses 13, and are sunk into the case hook mounting recesses 13. go. Then (at the moment when the handle case 1 is pushed into the mounting opening P0 of the door panel P), the locking claws 15C of the case hooks 15 are completely inserted into the case hook mounting recesses 13, and the handle case 1 is closed. It completely passes through the mounting opening P0 of the door panel P, and the flange 11 around the entire peripheral edge of the front opening 10 of the handle case 1 reaches the entire peripheral edge of the mounting opening P0 on the front side of the door panel P via the case packing 110. The case hooks 15 in the case hook mounting recesses 13 pass through the mounting openings P0 of the door panel P so that the case hooks 15 and the case hook mounting recesses 13 are connected to each other on the back side of the door panel P. By the biasing force (elastic return of the coil spring 17) of the coil spring 17 between and Rotates outward from the case hook mounting recesses 13, protrudes outward from the case hook mounting recesses 13, and elastically engages with the short side and long side edges of the mounting opening P0 of the door panel P. be done. Here, as shown in FIG. 3, the handle H is arranged such that the center of rotation C1 of each case hook 15 is on the side of one end 15a of each case hook 15 and is slightly inside between the outer surface 15d and the inner surface 15e. The other end 15f of each case hook 15 is located closer to the inner surface 15e than the center of rotation C1 of each case hook 15 and closer to the one end 15a of each case hook 15 than the center of rotation C1 of each case hook 15. Since each case hook 15 is formed in a substantially circular arc shape, the arc-shaped portion of each locking claw 15C moves to the edge of the mounting opening P0 of the door panel P as the locking claw 15C rotates outward. , and bites into each of the short-side and long-side edges of the mounting opening P0. On the front side of P, the handle H is drawn around the entire periphery of the mounting opening P0 and press-contacted, and the handle H is firmly attached and fixed to the door panel P. In this way, the handle H can be easily and reliably fixed to the door panel P with one touch.

この平面ハンドルとしてのワンタッチ取付ハンドルＨにおいて、ハンドル軸（回転軸）３と止め金４とのワンタッチ取付構造Ｓは、止め金４の正面、背面間を貫通して形成される取付孔４０と、ハンドル軸３の先端に設けられる止め金取付部３Ａとにより構成される。 In the one-touch mounting handle H as a flat handle, the one-touch mounting structure S between the handle shaft (rotating shaft) 3 and the clasp 4 includes a mounting hole 40 formed through the front and back surfaces of the clasp 4, It is composed of a clasp attachment portion 3A provided at the tip of the handle shaft 3.

このようにして止め金４はハンドル軸３先端の止め金取付部３Ａに回転不能に取り付けられて、ハンドルレバー２を任意の引き起こし位置で所定の開方向に回すことにより、ハンドルレバー２とハンドル軸３の間の回動軸５を介してハンドル軸３を同方向に一体回転して、止め金４がキャビネット本体などの固定枠体側の受け金に係合し、ハンドルレバー２をこれとは反対の閉方向に回すと、回動軸５を介してハンドル軸３を同方向に一体回転して、止め金４がキャビネット本体などの固定枠体側の受け金から離脱するようになっている。 As shown in FIG. 4, the clasp 4 is integrally formed from an iron or stainless steel plate by pressing (punching), and is formed into a substantially L-shape that faces sideways when viewed from the front and from the rear. A mounting hole 40 is formed in the vicinity of the end of the horizontal portion 41 on the side of the vertical portion 41 so as to correspond to the clasp mounting portion 3A at the tip of the handle shaft 3 . In this case, the mounting hole 40 is formed in a rectangular shape (substantially square).
In this manner, the clasp 4 is non-rotatably attached to the clasp mounting portion 3A at the tip of the handle shaft 3. By turning the handle lever 2 in an arbitrary raised position in a predetermined opening direction, the handle lever 2 and the handle shaft are opened. The handle shaft 3 is rotated integrally in the same direction via the rotating shaft 5 between the 3, the stopper plate 4 is engaged with the receiving plate on the fixed frame side of the cabinet body, etc., and the handle lever 2 is rotated in the opposite direction. When it is turned in the closing direction, the handle shaft 3 is integrally rotated in the same direction via the rotary shaft 5, and the stopper plate 4 is separated from the receiving plate on the fixed frame side of the cabinet body or the like.

ハンドル軸３は、図５に示すように、先端の基本形状が角形、この場合、断面四角形で所定の長さに形成され、止め金取付３Ａ部はこのハンドル軸３の角形の先端に、既述のとおり、複数の止め金フック取付凹部３３、及び複数の軸受３４と、複数の止め金フック３５（図２参照）と、一つ又は複数のばね部材３７（図２参照）とを備えて構成される。 As shown in FIG. 5, the handle shaft 3 has a basic shape of a square tip, in this case a square cross section and a predetermined length.

Further, each clasp hook 35 is formed such that an outer surface 35 d is substantially parallel to each surface forming the peripheral surface 32 at the tip of the handle shaft 3 . One end 35a, that is, between one end of the outer surface 35d and one end of the inner surface 35e, is formed in a substantially V-shaped protrusion in cross section, and one surface continuous with the outer surface 35d is formed into a predetermined arc-shaped surface, and the inner surface The other surface continuous with 35e is formed as an inclined surface with a predetermined angle. The other surface that is continuous with the inner surface 35e is formed at a predetermined angle with the one surface that is continuous with the outer surface 35d, forming a stopper 351 that can be engaged with the bottom of the clasp hook mounting recess 33. Due to the contact engagement between the stopper 351 and the bottom of the clasp hook mounting recess 33, each clasp hook 35 is excessively rotated in the projecting direction from the clasp hook mounting recess 33, that is, each clasp hook. 35 is restricted from protruding out of each catch hook mounting recess 33 . Then, the inner surface 35e is formed symmetrically with the outer surface 35d so as to be parallel to the outer surface 35d or in a direction that is slightly wider than parallel, in this case, in a direction that is slightly wider than parallel. Here, the outer surface 35d and the inner surface 35e of each clasp hook 35 are square planes, and the left and right side portions 35b and 35c are square planes narrower than the width of the outer surface 35d and the inner surface 35e. The portion 35a has a substantially V-shaped cross section. In this case, one surface continuous with the outer surface 35d is a predetermined arcuate surface, and the other surface continuous with the inner surface 35e is an inclined surface (stopper 351) with a predetermined angle. In addition, the other end 35f is a quadrangular surface narrower than the outer surface 35d and the inner surface 35e and has an arcuate cross section. Due to the shape of the clasp hook 35, it is formed in a small size according to the clasp hook mounting recess 33 formed in the limited space of the peripheral surface 32 at the tip of the handle shaft 3, and attached to the clasp hook mounting recess 33. be able to.

It is arranged so as to be able to appear and disappear outside of the upper surface portion 321 and the lower surface portion 322 .
In this case, since one coil spring (hereinafter referred to as coil spring 37) is used as one or more spring members 37 as described later, the inner surface 35e of each stopper hook 35 has a bottomed (cylindrical) cylindrical shape. holes 352 are formed, and one coil spring 37 is held at both ends in the holes 352 of each detent hook 35 and interposed between the detent hooks 35 .
The hole 352 of each clasp hook 35 is formed before or after the tip of the handle shaft 3 is passed through the mounting hole 40 of the clasp hook 4 together with each clasp hook 35 . When the coil spring 35C protrudes outward from each clasp hook mounting recess 33 from each surface forming the peripheral surface 32 at the tip of the handle shaft 3, the coil spring 37 is deformed into an arc shape convex toward the flange 11 side of the handle case 1. It is possible to form a predetermined angle with respect to the inner surface 35e of each clasp hook 35, and one end 35a side and the other end of each clasp hook 35 of the hole 352 of each clasp hook 35 A portion of the inner peripheral surface on the side of 35f is formed between the tip of the handle shaft 3 and the stopper hooks 35 and the attachment hole 40 of the stopper plate 4, and the locking claws 35C of the stopper hooks 35 The coil spring 37 can be deformed and guided in a convex arc shape to the opposite side of the flange 11 of the handle case 1 when it is inserted into the stopper hook mounting recess 33, and is gradually moved from the inner side of the hole 352 toward the opening side. It is formed with a pre-determined angle of bevel that expands.

一つ又は複数のばね部材３７は各止め金フック取付凹部３３間を貫通して各止め金フック３５間に又は各止め金フック３５と各止め金フック取付凹部３３との間に介装され、各係止爪３５Ｃを常態として各止め金フック取付凹部３３からハンドル軸３の先端側の周面３２をなす各面の外側へ突出可能に回動付勢する。
この場合、一つのコイルスプリング３７が用いられ、コイルスプリング３７は、ハンドル軸３先端の上面部３２１、下面部３２２の各止め金フック取付凹部３３間のばね通し部３２０を通じて一端が上面部３２１のケースフック取付凹部３３内の止め金フック３５の孔３５２の底部に取り付けられ、他端が下面部３２２のケースフック取付凹部３３内の止め金フック３５の孔３５２の底部に取り付けられて、上下の各止め金フック３５間に介装され、各止め金フック３５の各係止爪３５Ｃを常態として各止め金フック取付凹部３３からハンドル軸３先端の周面３２をなす上面部３２１、下面部３２２の外側へ突出可能に回動付勢し、そして、既述のとおり、各止め金フック３５のストッパー３５１と各止め金フック取付凹部３３の底部との衝接係合により、各止め金フック３５の各止め金フック取付凹部３３から突出方向への過度の回動、すなわち各止め金フック３５の各止め金フック取付凹部３３からの飛び出しを規制される。
なお、ここではハンドル軸３先端の止め金取付部３Ａに一対の止め金フック３５が１組設けられているため、コイルスプリング３７は一つのみ用いられたが、一対の止め金フック３５が２組以上設けられることで、複数のコイルスプリングが採用される one or more spring members 37 pass through the clasp hook mounting recesses 33 and are interposed between the clasp hooks 35 or between the clasp hooks 35 and the clasp hook mounting recesses 33; Each locking claw 35C is turned to the normal state and is urged to rotate so as to protrude outward from each surface forming the peripheral surface 32 on the distal end side of the handle shaft 3 from each stopper hook mounting recess 33 .
In this case, a single coil spring 37 is used, and one end of the coil spring 37 passes through the spring through portion 320 between the stopper hook mounting recesses 33 of the upper surface portion 321 and the lower surface portion 322 of the handle shaft 3 . It is attached to the bottom of the hole 352 of the clasp hook 35 in the case hook mounting recess 33, and the other end is attached to the bottom of the hole 352 of the clasp hook 35 in the case hook mounting recess 33 of the lower surface portion 322. An upper surface portion 321 and a lower surface portion 322 which are interposed between the clasp hooks 35 and form the peripheral surface 32 from the clasp hook mounting recess 33 to the tip of the handle shaft 3 with the locking claws 35C of the clasp hooks 35 in the normal state. , and as described above, each clasp hook 35 is engaged with the stopper 351 of each clasp hook 35 and the bottom of each clasp hook mounting recess 33 by impact engagement. Excessive rotation in the projecting direction from each clasp hook mounting recess 33 , that is, each clasp hook 35 is restricted from jumping out of each clasp hook mounting recess 33 .
In this case, only one coil spring 37 is used because a pair of detent hooks 35 is provided on the detent mounting portion 3A at the tip of the handle shaft 3, but two detent hooks 35 are used. Multiple coil springs are adopted by providing more than one set

このようにして止め金４のハンドル軸３先端の止め金取付部３Ａへの取り付けに当たり、ハンドル軸３を止め金４の取付孔４０に止め金４の正面側から背面側へ挿入するとともに、ハンドル軸３の先端の各止め金フック３５を止め金４の取付孔４０の縁部で押圧して各止め金フック取付凹部３３に没入させながら取付孔４０を止め金４の正面側から背面側へ通し、止め金４の背面側で各止め金フック３５をハンドル軸３先端の周面３２をなす各面から外側へ突出させて、止め金４の正面側でハンドルケース１（ハンドル取付部１０３）の背面を取付孔４０の縁部周囲に圧接させるとともに、止め金４の背面側で各止め金フック３５の各係止爪３５Ｃを取付孔４０の縁部又は縁部周囲に係止させて、止め金４をハンドル軸３にワンタッチで取り付けるようになっている。 In this manner, when attaching the stopper plate 4 to the stopper plate mounting portion 3A at the tip of the handle shaft 3, the handle shaft 3 is inserted into the mounting hole 40 of the stopper plate 4 from the front side to the rear side of the stopper plate 4, and the handle is Each clasp hook 35 at the tip of the shaft 3 is pressed by the edge of the mounting hole 40 of the clasp 4 to sink into each clasp hook mounting recess 33, and the mounting hole 40 is moved from the front side to the back side of the clasp 4. Each hook 35 is projected outward from each surface forming the peripheral surface 32 of the distal end of the handle shaft 3 on the back side of the clasp 4, and the front side of the clasp 4 is attached to the handle case 1 (handle mounting portion 103). is pressed against the periphery of the mounting hole 40, and the locking claws 35C of the respective locking metal hooks 35 are locked on the edge of the mounting hole 40 or around the edge on the back side of the locking metal 4, The stopper plate 4 is attached to the handle shaft 3 with one touch.

図７に止め金４のハンドル軸３先端の止め金取付部３Ａに対する取り付け方法を併せて示している。
なお、止め金取付部３Ａは、止め金４を止め金取付部３Ａに取り付ける前の通常の状態では、ハンドル軸３の先端周面３２の各止め金フック３５が各止め金フック３５間のコイルスプリング３７により相互に外側方向に回動付勢されて、各止め金フック３５の各係止爪３５Ｃが各止め金フック取付凹部３３からハンドル軸３の先端周面３２の各面の外側へ弾性的に突出され、また、各止め金フック３５の一方の端部３５ａの内面３５ｅ側のストッパー３５１と各止め金フック取付凹部３３の底部との衝接係合により、各止め金フック３５の各止め金フック取付凹部３３からの過度の飛び出しが防止される。 FIG. 7 also shows a method of attaching the clasp 4 to the clasp mounting portion 3A at the tip of the handle shaft 3. As shown in FIG.
In addition, in the normal state before the clasp 4 is attached to the clasp mounting portion 3A, the clasp hooks 35 on the distal end peripheral surface 32 of the handle shaft 3 are coiled between the clasp hooks 35. The springs 37 urge the latching hooks 35C of the stopper hooks 35 to rotate outwardly, and the locking claws 35C of the stopper hooks 35 are elastically moved from the stopper hook mounting recesses 33 to the outer sides of the distal end peripheral surface 32 of the handle shaft 3. Also, each of the catch hooks 35 is engaged with the bottom of each catch hook mounting recess 33 by a stopper 351 on the inner surface 35e side of one end 35a of each catch hook 35 and the bottom of each catch hook mounting recess 33. Excessive protrusion from the clasp hook mounting recess 33 is prevented.

図７において、止め金４をハンドル軸３の先端に取り付けるに当たり、まず、止め金４の取付孔４０とハンドル軸３の先端の上下の向きを合せて、ハンドル軸３の先端を止め金フック３５とともに止め金４の取付孔４０に差し込み、押し込む（ワンプッシュする）。
このようにすると、ハンドル軸３の先端は、ハンドル軸３の先端周面３２の各面が先端から中間へ、中間から基端へ止め金４の取付孔４０の各縁部を摺動しつつ、止め金４の取付孔４０を通過する。この間、ハンドル軸３先端の上面部３４１、下面部３４２の各止め金フック取付凹部３３から外側に突出される各止め金フック３５の各係止爪３５Ｃは止め金４の取付孔４０の上下の各縁部に接触して押圧され、各係止爪３５Ｃが各止め金フック３５間のコイルスプリング３７（図２参照）の付勢力に抗して（コイルスプリング３７を圧縮しながら）各止め金フック取付凹部３３内に向けて回動し没入されていく。そして（ハンドル軸３の先端が止め金４の取付孔４０に押し込まれた瞬間）、各止め金フック３５の各係止爪３５Ｃが完全に各止め金フック取付凹部３３内に没入されて、ハンドル軸３の先端が止め金４の取付孔４０を完全に通過し、ハンドルケース１のハンドル取付部１０３の背面部が止め金４の正面側で取付孔４０の全周縁部の周囲に当接するとともに、各止め金フック取付凹部３３内の各止め金フック３５は止め金４の取付孔４０の通り抜けにより止め金４の背面側で各止め金フック３５間のコイルスプリング３７の付勢力（コイルスプリング３７の弾性復帰）により各止め金フック３５の各係止爪３５Ｃが各止め金フック取付凹部３３から外側へ向けて回動し各止め金フック取付凹部３３から外側に突出されて、止め金４の取付孔４０の上下の各縁部に弾性係止される。ここで、この止め金フック３５は、図６に示したように、各止め金フック３５の回動中心Ｃ２が各止め金フック３５の一方の端部３５ａ側でかつ外面３５ｄと内面３５ｅとの間の少し外面３５ｄ寄りに設けられ、各止め金フック３５の他方の端部３５ｆが円の中心を各止め金フック３５の回動中心Ｃ２よりも各止め金フック３５の一方の端部３５ａに近くかつ内面３５ｅ寄りの位置におく円弧状に形成されたことで、各止め金フック３５は、各係止爪３５Ｃの外側への回動とともに各係止爪３５Ｃの円弧状の部分が止め金４の取付孔４０の上下の各縁部に向けて迫り出して、取付孔４０の上下の各縁部に食い込み、これにより、ハンドルケース１のハンドル取付部１０３の背面部は止め金４の正面側で取付孔４０の全周縁部の周囲に圧接されて、止め金４がハンドル軸３先端の止め金取付部３Ａに強固に取り付け固定される。このようにして止め金４をハンドルケース１のハンドル取付部１０３から突出されるハンドル軸３先端の止め金取付部３Ａにワンタッチで簡易にしかも確実に固定することができる。 Referring to FIG. 7, when attaching the clasp 4 to the tip of the handle shaft 3, first, the mounting hole 40 of the clasp 4 and the tip of the handle shaft 3 are aligned vertically, and the tip of the handle shaft 3 is attached to the clasp hook 35.

During this time, the engaging claws 35C of the stopper hooks 35 protruding outward from the stopper hook mounting recesses 33 of the upper surface portion 341 and the lower surface portion 342 of the handle shaft 3 are positioned above and below the mounting hole 40 of the stopper plate 4. Each locking pawl 35C contacts each edge and is pressed against the biasing force of the coil spring 37 (see FIG. 2) between each hook 35 (while compressing the coil spring 37). It rotates toward the inside of the hook attachment recessed part 33, and is immersed. Then (at the moment when the tip of the handle shaft 3 is pushed into the mounting hole 40 of the clasp 4), the locking claws 35C of the clasp hooks 35 are completely immersed in the clasp hook mounting recesses 33, and the handle is The tip of the shaft 3 completely passes through the mounting hole 40 of the clasp 4, and the rear surface of the handle mounting portion 103 of the handle case 1 abuts against the entire periphery of the mounting hole 40 on the front side of the clasp 4. , each of the catch hooks 35 in each catch hook mounting recess 33 passes through the mounting hole 40 of the catch 4, and the biasing force of the coil spring 37 between the catch hooks 35 on the back side of the catch 4 (coil spring 37 35C of each stop metal hook 35 rotates outward from each stop metal hook mounting recess 33 and protrudes outward from each stop metal hook mounting recess 33, thereby releasing the stop metal 4. The upper and lower edges of the mounting hole 40 are elastically locked. Here, as shown in FIG. 6, the clasp hooks 35 are arranged so that the center of rotation C2 of each clasp hook 35 is on the one end 35a side of each clasp hook 35 and between the outer surface 35d and the inner surface 35e. The other end portion 35f of each clasp hook 35 is provided slightly closer to the outer surface 35d between the Since each clasp hook 35 is formed in an arcuate position close to and near the inner surface 35e, the arcuate portion of each locking claw 35C moves along with the outward rotation of each locking claw 35C. 4 protrudes toward the upper and lower edges of the mounting hole 40 and bites into the upper and lower edges of the mounting hole 40 , so that the rear surface of the handle mounting portion 103 of the handle case 1 faces the stopper plate 4 . The side of the mounting hole 40 is pressed against the entire periphery of the mounting hole 40 , and the clasp 4 is firmly attached and fixed to the clasp mounting portion 3 A at the tip of the handle shaft 3 . In this manner, the clasp 4 can be easily and reliably fixed to the clasp mounting portion 3A at the tip of the handle shaft 3 projecting from the handle mounting portion 103 of the handle case 1 with one touch.
