Description

この発明は、角軸と操作部材の連結機構（以下単に連結機構という）に係り、特に、扉を貫通する角軸を介して相互に連結されたハンドル等の操作部材を一動作で扉に装着できると共に、ガタが生じない連結機構に関する。   The present invention relates to a connecting mechanism (hereinafter simply referred to as a connecting mechanism) between an angular shaft and an operating member, and in particular, an operating member such as a handle connected to each other via an angular shaft penetrating the door is attached to the door in one operation. The present invention relates to a coupling mechanism that can be played and does not cause backlash.

ここで、角軸とは、扉の自由側端縁部及びここに埋設された錠箱を厚さ方向に貫通するようにして扉に装着され、その両端に装着された外側及び内側操作部材の動きを錠箱の錠止部材に伝達するもので、その存在そのものは従来周知である。   Here, the square axis is attached to the door so as to penetrate the free side edge of the door and the lock box embedded therein in the thickness direction, and the outer and inner operation members attached to both ends thereof. The movement is transmitted to the locking member of the lock box, and its existence is well known in the art.

本出願人は、先に、後記特許文献１及び２を以て、エスカチオンの扉への新規な取付機構を提案した。   The present applicant has previously proposed a novel attachment mechanism of an escation to a door using Patent Documents 1 and 2 described later.

なお、エスカチオンとは、図１に示すように、錠箱を埋設した扉の自由側端縁部を挟むようにしてその内外面に装着され、ハンドルやノブの取付座となる通常は縦長の一対の飾り板１、２のことである。   In addition, as shown in FIG. 1, an escation is a pair of usually elongated panels that are mounted on the inner and outer surfaces of the door with the lock box embedded therein, sandwiching the free side edge and serving as a handle or knob mounting seat. It is a decorative board 1 and 2.

このエスカチオンの取付機構については、特許文献１、２に詳細に記載されているので簡単に説明すると、外側及び内側エスカチオン１、２を扉内外面の所定の位置に押しつけるようにすると、先ず図１で下方のカプラー３が結合される。   Since this escation mounting mechanism is described in detail in Patent Documents 1 and 2, when briefly described, when the outer and inner escations 1 and 2 are pressed against predetermined positions on the inner and outer surfaces of the door, In FIG. 1, the lower coupler 3 is coupled.

次いで室内側から連結杆４を差込み、その大径頭部を外側に押動すると、捩りコイルばね５の弾力により連結杆４が回転し、その先端の係止爪６を図示しない段部に係止するので、ねじ止め等の組立作業無しに簡単な操作でエスカチオンを取付けることができる。
特願２００３−１５８０８４ 特願２００３−１７８１１５ Next, when the connecting rod 4 is inserted from the indoor side and the large-diameter head is pushed outward, the connecting rod 4 is rotated by the elastic force of the torsion coil spring 5, and the engaging claw 6 at the tip is engaged with the step (not shown). Since it stops, the escation can be attached by a simple operation without assembly work such as screwing.
Japanese Patent Application No. 2003-158084 Japanese Patent Application No. 2003-178115

この発明は、上記した新規なエスカチオンの取付機構において、そのハンドル等の操作部材の取付孔７、７の部分を挟みつけ、エスカチオンの弛みや浮き上がりを防止できる角軸と操作部材の連結機構を提供することを目的としている。   The present invention is a coupling mechanism for an operating shaft and a square shaft that can clamp the operating holes 7 and 7 of the operation member such as the handle and prevent the escation from loosening and floating. The purpose is to provide.

上記の目的を達成するため、請求項１に記載の発明は、外端部に外側操作部材を装着し、内端部に雌ねじ孔を形成した角軸を、室外側から扉を貫通させて内端部を室内側に突出させ、この角軸の内端部に、一端にフランジを形成した角筒状のブッシュを締り嵌めの態様で、かつ、フランジを扉内面側にして嵌合させ、更に、内側操作部材の一端に開口した差込み孔にブッシュ及び角軸を嵌合させた状態で内側操作部材と外側操作部材を相互に近接する方向に押動し、以て、ブッシュと角軸の摩擦係合によって角軸を確りと掴持し、角軸の長さ方向における相対位置を安定的に保持するブッシュのフランジと外側操作部材との間に扉面或いはエスカチオンを安定的に挟み、一方、内側操作部材に開口した角軸の長さ方向に長いねじ穴を挿通し、角軸の雌ねじ孔と螺合する止めビスにより、角軸と内側操作部材を相互に結合したことを特徴とする。 In order to achieve the above object, the invention according to claim 1 is characterized in that an outer operation member is attached to the outer end portion and a square shaft having a female screw hole formed in the inner end portion is passed through the door from the outdoor side. An end is protruded indoors, and a rectangular tube-like bush having a flange formed at one end is fitted into the inner end of this angular shaft in an interference-fit manner, and the flange is fitted to the inner surface of the door. The inner operating member and the outer operating member are pushed toward each other in a state where the bush and the angular shaft are fitted in the insertion hole opened at one end of the inner operating member, so that the friction between the bush and the angular shaft is caused. The door surface or escation is stably sandwiched between the flange of the bush and the outer operation member that holds the angular axis firmly by engagement and stably holds the relative position in the length direction of the angular axis. , Through a long screw hole in the length direction of the square axis opened in the inner operation member, By screwing the internally threaded hole and screwed in the shaft, characterized in that combining square shaft and an inner operating member to each other.

また、請求項２に記載の発明は、上記ブッシュが合成樹脂製であることを特徴とする。   The invention according to claim 2 is characterized in that the bush is made of a synthetic resin.

この発明は、ブッシュと角軸の摩擦係合によりブッシュを角軸の所定の位置に安定に、かつ、強固に固定できるから、外部操作部材とブッシュとの間にエスカチオンを挟みつけた場合には、エスカチオンの取付状態をガタ無く安定に保持し続けることができる。   In the present invention, since the bush can be stably and firmly fixed to a predetermined position of the angular axis by friction engagement between the bush and the angular axis, the escation is sandwiched between the external operation member and the bush. Can keep the attachment state of the escation stably without any play.

また、エスカチオンを装着しない扉にもこの発明を適用することができ、この場合には、ブッシュを締り嵌めの態様で角軸に嵌める、という簡単な構造で、操作部材をガタや弛みの無い状態で安定に扉に装着できる、等種々の効果を奏する。   The present invention can also be applied to doors that are not equipped with an escation. In this case, the operation member is not loose or loose with a simple structure in which the bush is fitted to the square shaft in an interference fit manner. Various effects such as being able to be mounted on the door in a stable state.

操作部材をガタや弛みの無い状態で安定に扉に装着し、或いは、エスカチオンの取付状態を安定に保持する、という目的を、ブッシュを締り嵌めの態様で角軸に嵌める、という簡単な構造で実現した。   A simple structure that fits the bushing to the square shaft in an interference-fitting manner for the purpose of stably mounting the operation member on the door without looseness or looseness, or maintaining the escation mounting state stably. Realized.

以下、この発明の一実施例を図面を参照して説明する。
図２及び図３において符号８は角軸を示し、この角軸８は、従来の角軸と同様の断面が方形の杆体であり、その外端部（図で左端部には）ピン穴９が、内端部には雌ねじ孔１１が夫々開口している。 An embodiment of the present invention will be described below with reference to the drawings.
2 and 3, reference numeral 8 denotes an angular axis. The angular axis 8 is a rectangular body having a rectangular cross section similar to that of the conventional angular axis, and has a pin hole 9 at an outer end portion thereof (at the left end portion in the drawing). However, female screw holes 11 are opened at the inner end portions.

この発明においても、従来の外部操作部材と角軸の結合態様と同様に、外部操作部材１２の軸部、及びこれに差込まれた角軸８を貫通する割りピン１３（図３参照）により、容易に分離できないように結合される。   Also in the present invention, in the same manner as in the conventional coupling mode between the external operation member and the angular axis, the shaft portion of the external operation member 12 and the split pin 13 (see FIG. 3) penetrating the angular axis 8 inserted therein. Combined so that it cannot be easily separated.

一方、角軸の内端部には、図３に示すように、フランジ１４付のブッシュ１５が、フランジ１４を扉側に向けて嵌合している。   On the other hand, as shown in FIG. 3, a bush 15 with a flange 14 is fitted to the inner end portion of the square shaft with the flange 14 facing the door.

このブッシュ１５は、例えば図４乃至図６に示すように、円板状のフランジ１４付の薄肉角筒状で、ブッシュ１５と角軸８との嵌合の態様は所謂締り嵌めとなっている。   As shown in FIGS. 4 to 6, for example, the bush 15 has a thin rectangular tube shape with a disk-like flange 14, and the bush 15 and the square shaft 8 are fitted with a so-called interference fit. .

ここで締り嵌めとは、ブッシュ１５と角軸８とを嵌め合せたときの隙間がマイナスとなる嵌合の態様をいい、この場合弾性変形によってブッシュ１５が少し外側に膨らみ、その角筒が元に戻ろうとする弾力により角軸８が締め付けられ、両者の間に強い摩擦係合が生じる。   Here, the interference fit refers to a form of fitting in which the gap when the bush 15 and the square shaft 8 are fitted is negative. In this case, the bush 15 slightly expands outward due to elastic deformation, and the square tube is original. The angular shaft 8 is tightened by the elastic force to return to the position, and a strong frictional engagement occurs between the two.

ちなみに、図示の実施例では、角軸８とブッシュ１５との嵌合が確実に締り嵌めとなるように、図６に示すように、角筒内筒内の隅部に所定の幅、所定の長さの低い突条、すなわち、角筒中心軸線方向の突出量が小さい突条１６を形成し、角軸８に嵌め合わせたとき、この突条に応力が集中して弾性変形がこの部分で生じるように設計されている。   Incidentally, in the illustrated embodiment, as shown in FIG. 6, a predetermined width and a predetermined width are provided at the corners of the inner cylinder of the square tube so that the fitting between the square shaft 8 and the bush 15 is an interference fit. When a protrusion 16 having a small length, that is, a protrusion 16 having a small protrusion amount in the direction of the central axis of the rectangular tube, is formed and fitted to the square shaft 8, stress is concentrated on the protrusion and elastic deformation occurs at this portion. Designed to result.

なお、弾性変形し易い、という観点から、また、締り嵌めという態様で嵌合してもブッシュ１５が角軸８と抉らずに角軸８に沿って移動できるように、ブッシュ１５の材質は例えばナイロン系の合成樹脂であることが望ましい。   The material of the bushing 15 is such that the bushing 15 can move along the angular axis 8 without interfering with the angular axis 8 from the viewpoint that it is easily elastically deformed, and even when fitted with an interference fit. For example, a nylon synthetic resin is desirable.

一方、図３及び図７に示すように、内側操作部材１７の軸部にもこれと同軸に段付の差込孔１７が形成されている。   On the other hand, as shown in FIGS. 3 and 7, a stepped insertion hole 17 is formed coaxially with the shaft portion of the inner operation member 17.

なお、この差込孔１７と角軸８或いはブッシュ１５との嵌合は、所謂止まり嵌め、或いは緩み嵌めで良い。   The fitting between the insertion hole 17 and the square shaft 8 or the bush 15 may be a so-called dead fit or a loose fit.

また、内側操作部材１７の軸部の所定の角度位置には、角軸の長さ方向に長いねじ穴１９が開口している。   Further, a screw hole 19 that is long in the length direction of the angular axis is opened at a predetermined angular position of the shaft portion of the inner operation member 17.

上記のように構成されたこの発明の一実施例による連結機構は、先ず外端部に外側操作部材のみを装着した角軸８を、エスカチオンの前記取付孔７（図１参照）及び扉、錠箱の図示しない角穴を通してその内端部を室内側に突出させる。   In the connecting mechanism according to the embodiment of the present invention configured as described above, first, the angular shaft 8 having only the outer operation member mounted on the outer end thereof is connected to the mounting hole 7 (see FIG. 1) of the escation, the door, The inner end portion of the lock box is protruded indoors through a square hole (not shown).

そして、この内端部にブッシュ１５及び内側操作部材１７を嵌合させ、止めビス２１（図３参照）をねじ穴１９を通して仮に角軸の前記雌ねじ孔１１に螺着する。   Then, the bush 15 and the inner operation member 17 are fitted to the inner end portion, and a set screw 21 (see FIG. 3) is temporarily screwed through the screw hole 19 into the female screw hole 11 of the square shaft.

しかる後、例えば内側及び外側操作部材１２、１７を両手で持って外側操作部材１２を固定した状態で内側操作部材を１７を扉面方向に押動すると、ブッシュ１５及び内側操作部材１７が一体になって扉面方向に移動し、例えば内側及び外側操作部材１２、１７の段部が夫々エスカチオンの取付孔１７の面取り部に接合するので、その状態で止めビス２１を堅く締め付けて角軸８と内側操作部材１７とを固定する。   After that, for example, when the inner operation member 12 and 17 are held with both hands and the outer operation member 12 is fixed, the inner operation member 17 is pushed in the door surface direction, the bush 15 and the inner operation member 17 are integrated. Then, for example, the step portions of the inner and outer operation members 12 and 17 are joined to the chamfered portions of the escation mounting holes 17, respectively. And the inner operation member 17 are fixed.

この状態では内側及び外側操作部材１２、１７は扉面内外からエスカチオン１、２を強く挟み付け、その状態はブッシュ１５と角軸８の摩擦係合によって安定に保たれる。   In this state, the inner and outer operation members 12 and 17 strongly hold the escations 1 and 2 from inside and outside the door surface, and this state is stably maintained by the frictional engagement between the bush 15 and the square shaft 8.

なお、この発明は、エスカチオンの締め付けに限らず、エスカチオンを装着しない通常の扉における操作部材の取付にも適用できることは勿論である。   Of course, the present invention is not limited to the tightening of the escation, but can be applied to the mounting of the operation member in a normal door to which the escation is not mounted.
