Description
本発明は、上吊式の引戸を、引戸側に設けられたキャッチ手段と、取付けベース側に設けられたマグネット手段の吸着磁力とによって、全開または全閉位置で保持する引戸の位置保持装置に関する。 The present invention relates to a position-holding device for a sliding door that holds an upper suspension type sliding door in a fully open or fully closed position by catch means provided on the sliding door side and an attractive magnetic force of magnet means provided on the mounting base side.
従来、建物の出入り口や鉄道車両の客車間開口部等における上吊式の引戸には、引戸を全開状態または全閉状態に保持するために、マグネット（永久磁石）の吸着磁力を利用するようにしたものが知られている（特許文献１、２参照）。
特許文献１のものは、吊り車のハンガー金具（６）に吸着部（４）を取着し、ハンガーレール（２）が設けられた取付けベース固定側（２Ａ）に、永久磁石としての吸着ストッパ（３）を取着して、全開または全閉位置で吸着部（４）を吸着ストッパ（３）に吸着させるようにしたものであり、特許文献２のものは、定置吸引部（２１ｂ）の永久磁石（２１）とキャッチ部としての可動吸引部（２５ｂ）とを隙間Ｓを存して非接触状態で対面させ、永久磁石の吸引磁力によって、引戸の全開または全閉位置で保持し、隙間（Ｓ）を近接離間操作することで永久磁石の吸引磁力の強弱を調整するようにしたものである。
Conventionally, for the suspension type sliding doors at the entrances and exits of buildings and the opening between passenger cars of railway vehicles, the attractive magnetic force of magnets (permanent magnets) is used to keep the sliding doors fully open or fully closed. Those are known (see Patent Documents 1 and 2).
In Patent Document 1, an adsorption portion (4) is attached to a hanger bracket (6) of a suspension car, and an adsorption stopper as a permanent magnet is attached to a mounting base fixing side (2A) provided with a hanger rail (2). (3) is attached and the adsorbing part (4) is adsorbed to the adsorbing stopper (3) in the fully open or fully closed position. The permanent magnet (21) and the movable suction portion (25b) as the catch portion are faced in a non-contact state with a gap S, and are held in the fully open or fully closed position of the sliding door by the attractive magnetic force of the permanent magnet. The strength of the attractive force of the permanent magnet is adjusted by performing the proximity and separation operation of (S).
ところで、鉄道車両の客車間開口部等における上吊式の引戸（妻引戸）は、人の乗り降りやカーブ走行等の際に、車体自身が揺れたり傾いたり、遠心力が掛かるなどして、引戸に対してその吸着保持状態を解離するような外力を受けるため、このような解離作用を受けても引戸を全開または全閉位置で確実に位置保持する必要がある。
しかしながら、特許文献１のものでは、確実な吸着保持ができるものの、妻引戸はその重量もばらばら（３５kg〜６０kg程度）で、引戸重量ごとに、その都度異なる吸引磁気力のマグネットを選定し、吸着保持力の設定をして製作しなければならず、製作の煩雑化を招き多様性に欠けるだけでなく、マグネットに直接吸着させているため当接時に破損したり、衝突音を発するなどの問題点を有していた。一方、特許文献２のものでは、非接触状態で位置保持するので、マグネットの破損はある程度回避できるものの、隙間Ｓを狭めて設定すると閉戸時に戸先ゴムの弾性変形による影響を受けて吸着してしまったり、マグネットを破損してしまう危惧があり、しかも、マグネットとの保持位置における吸引磁力が安定せず、振動や傾動、遠心力といった外力を受けることによって離間し易く、引戸を安定的に位置保持できないため、車両用引戸に実質的に採用することができないという問題点を有していた。
なお、上記かっこ（）と共に付した符号は、各特許文献中で使用された符号である。
By the way, the upper suspension type sliding door (Tsumari sliding door) in the opening between passenger cars of railroad cars, etc., when the person gets on and off or runs on a curve, the car body itself shakes and tilts, or centrifugal force is applied to the sliding door. On the other hand, since an external force that dissociates the adsorption holding state is applied, it is necessary to securely hold the sliding door in the fully open or fully closed position even if it receives such a dissociating action.
However, although the thing of patent document 1 can perform reliable adsorption holding, the weight of the sliding door is different (about 35kg to 60kg), and a magnet with a different attractive magnetic force is selected for each sliding door weight. It has to be manufactured with a holding force setting, which leads to complicated manufacturing and lack of diversity, and because it is directly attracted to the magnet, it breaks at the time of contact and generates a collision sound. Had a point. On the other hand, in the case of Patent Document 2, since the position is held in a non-contact state, damage to the magnet can be avoided to some extent, but if the gap S is set narrow, it is attracted by the influence of elastic deformation of the door rubber when closing. or Tsu Teshima, there is fear that would damage the magnets, moreover, the suction force in the holding position of the magnet is not stabilized, easily separated by receiving an external force such as vibration or tilting, centrifugal force, stably sliding door Therefore, there is a problem that it cannot be practically used for a sliding door for a vehicle.

本発明は、上記のように構成したことにより、マグネットの吸着磁力を利用して引戸を全開または全閉位置で位置保持するものでありながら、強磁性体にて形成される当接部の挿通孔前周面にキャッチ部が当接した際、マグネット部の磁気力を、固定された磁路として機能する挿通孔の内周域を通って、漏洩磁束を減少して効率よく磁力伝達することができ、安定した磁界を形成し、キャッチ部を、マグネット部に直接当接させない非接触状態で、かつ揺動可能な状態で強固に吸着保持することができるだけでなく、マグネットの破損回避は勿論、閉戸時に戸先ゴムの弾性変形を受けても、キャッチ部が後方に揺動するので、面一に当接でき当接音の発生も抑止される。しかも、キャッチ部が当接部に磁力吸着した状態で、マグネット部との対面間隔を僅かな隙間に設定しても開閉に際して磁極短絡することがなく、精度良く近接離間する調整設定を行い得て、キャッチ部を介してマグネット部に流れる吸引磁気力の強弱を可変調整操作して、引戸ごとに最適な吸着磁力をもって位置保持設定することができる。その結果、自閉式引戸の戸先側と戸尻側の吸着保持力を異ならしめた設定や、開閉ストローク、大きさ、重量といった引戸ごとに異なる吸着保持力を個々別々に設定することができ、その都度マグネットの磁気力を選定する必要もなく、一種類のマグネット手段をもって適用の多様化と製作の一元化を図ることができると共に、車両用引戸の如く振動や傾動、遠心力といった外力の影響を受けても、これら外力に追随してキャッチ部が揺動し、吸着ズレが防止され面一な吸着状態が維持されて解離規制がなされ、引戸を位置保持することができる。 According to the present invention configured as described above, the sliding door is held in the fully open or fully closed position by using the magnetic attraction force of the magnet, and the contact portion formed of the ferromagnetic material is inserted. when the catch portion is in contact with the hole prior to the peripheral surface, the magnetic force of the magnet portion, through the inner peripheral region of the insertion hole functioning as a fixed magnetic path to magnetic transmission rather by efficiency by reducing leakage magnetic flux It is possible to form a stable magnetic field, firmly hold the catch part in a non-contact state that does not directly contact the magnet part and in a swingable state, and avoid damage to the magnet. Of course, even when the door rubber is elastically deformed when the door is closed, the catch portion swings backward, so that it can abut on the same surface and the generation of contact noise is also suppressed. Moreover, even when the catch part is magnetically attracted to the contact part, even if the facing distance from the magnet part is set to a slight gap, the magnetic pole is not short-circuited at the time of opening and closing, and it is possible to perform adjustment setting for close proximity and separation with high accuracy. In addition, the position of the sliding door can be set and maintained with an optimum attractive magnetic force by variably adjusting the strength of the attractive magnetic force flowing to the magnet portion via the catch portion. As a result, it is possible to set different suction holding force for each sliding door such as opening / closing stroke, size, weight, etc. It is not necessary to select the magnetic force of the magnet each time, and it is possible to diversify the application and unify the production with one type of magnet means, and to influence the external force such as vibration, tilting, centrifugal force like a sliding door for vehicles. Even if it is received, the catch portion swings following these external forces, the adsorption displacement is prevented, the flush adsorption state is maintained, the dissociation is restricted, and the sliding door can be held in position.

戸尻側に配設されるマグネット取付け基板６１は、マグネット部６２の背面側から突出するビス６２３を螺入し前面側でロックナット６２４により固定する固定片６１１と、吊り金具２１への取付け片６１２とで折曲形成され、当接部６３は、固定片６１１から折曲させた立上り片を介してマグネット取付け基板６１と一体成形されている。また、取付け片６１２には、長孔が穿設され、吊り金具２１へ取着する際に、キャッチ部５２がマグネット手段６に対面当接する位置を調整できるようになっている。
The magnet mounting substrate 61 disposed on the door end side includes a fixing piece 611 that is screwed into a screw 623 protruding from the back side of the magnet portion 62 and is fixed by a lock nut 624 on the back side, and a mounting piece to the mounting base 11. 612, a mounting piece 613 for mounting the contact portion 63 is integrally formed by bending. The contact portion 63 is formed in a U-shape in front view by bending the attachment pieces 632 and 632 above and below the contact surface with which the catch portion 52 abuts against the front peripheral surface of the insertion hole 631. Is fixed to the mounting piece 613 of the magnet mounting substrate 61, and the upper mounting piece 613 is also used as a bracket to which the self-closing device 3 is mounted.
The magnet mounting board 61 disposed on the door bottom side includes a fixing piece 611 that is screwed into a screw 623 protruding from the back side of the magnet portion 62 and is fixed by a lock nut 624 on the front side, and a mounting piece to the hanging bracket 21. The contact portion 63 is integrally formed with the magnet mounting substrate 61 via a rising piece bent from the fixed piece 611. Further, the attachment piece 612 is provided with a long hole so that the position where the catch portion 52 abuts against the magnet means 6 can be adjusted when the attachment piece 612 is attached to the hanging bracket 21.
つまり、固定片６１１と当接部６３とは、所定間隔を存して対向離間しており、マグネット部６２は、挿通孔６３１に挿入された状態で、その背面側から突出する固定片６１１に螺入されたビス６２３を介して取り付けられ、ビス６２３の螺合送り操作により、当接部６３の略板厚幅となる前面から後面より僅かに離間した挿通孔６３１の内周面域間の磁力伝達可能な範囲を、調整域Ｓとして進退移動させて位置決め調整可能に構成される。
一方、マグネット部６２の磁力は、ヨーク６２２の円周先端側に磁束誘導されたＮ極が、その前周端面から出て永久磁石６２１のＳ極表面に入る流れにより集束された磁界（磁束ループ）を形成するので、マグネット部６２を、強磁性体にて形成される当接部６３の挿通孔６３１から僅かに離間した状態から挿入された状態までの範囲内において、その内周面域にＮ極が磁束誘導される。このキャッチ部５２を当接させない状態では、挿通孔６３１の円周廻りとなる当接部６３の前周面域は殆ど吸着磁力を有しない。なお、本実施例では、ヨーク６２２の外周面を挿通孔６３１の内周面と僅かな隙間をもって挿入したが、接触した状態で挿入させても良く、当接部６３は板材で形成しその板厚を利用して調整域Ｓに設定したが、別途筒状部材を用いて挿通孔６３１に取着し調整域Ｓを長めに設定できるようにしても良く、要はヨーク６２２の磁極が強磁性体を介して磁束誘導されれば良い。
That is, the fixed piece 611 and the contact portion 63 are opposed to each other with a predetermined interval, and the magnet portion 62 is in a state of being inserted into the insertion hole 631 on the fixed piece 611 protruding from the back side. It is attached via a screwed screw 623, and between the inner peripheral surface regions of the insertion hole 631 slightly spaced from the rear surface from the front surface, which is substantially the plate thickness width of the contact portion 63, by screwing and feeding operation of the screw 623. The range in which the magnetic force can be transmitted is configured as an adjustment area S so that the position can be adjusted by moving forward and backward.
On the other hand, the magnetic force of the magnet part 62 is a magnetic field (flux loop) that is focused by the flow of the N pole, which is magnetically guided to the circumferential tip side of the yoke 622, from the front peripheral end face and enters the S pole surface of the permanent magnet 621. In the range from a state slightly spaced from the insertion hole 631 of the contact portion 63 formed of a ferromagnetic material to a state in which the magnet portion 62 is inserted, the magnet portion 62 is formed on the inner peripheral surface area thereof. The N pole is magnetically induced. In a state where the catch portion 52 is not brought into contact, the front peripheral surface area of the contact portion 63 that is around the circumference of the insertion hole 631 has almost no attractive magnetic force. In this embodiment, the outer peripheral surface of the yoke 622 is inserted with a slight gap from the inner peripheral surface of the insertion hole 631. However, the yoke 622 may be inserted in contact with each other. Although the adjustment area S is set using the thickness, the adjustment area S may be set longer by attaching it to the insertion hole 631 using a separate cylindrical member. In short, the magnetic pole of the yoke 622 is ferromagnetic. The magnetic flux may be induced through the body.
次に、キャッチ部５２を当接部６３に当接させた状態におけるマグネット部６２の吸着保持機能について、図７の戸先側におけるキャッチ部とマグネット部との吸着保持状態を示す要部断面図に基づいて説明する。この図に示すように、キャッチ部５２を、マグネット部６２に直接当接させない非接触状態で、挿通孔６３１の前周面域となる当接部６３に当接（接触）させると、予めヨーク６２２の磁極（Ｎ極）が磁束誘導された状態にある挿通孔６３１の内周域が磁路として機能し、この内周域を通ることで漏洩磁束を減少させ、瞬時にキャッチ部５２に環状で均等な磁力伝達がなされ、対向空間域を介してマグネット部６２（永久磁石６２１のＳ極表面）へ流れる効率のよい安定した磁界が形成されて磁力吸着がなされる。このキャッチ部５２が当接部６３に磁力吸着した状態におけるマグネット部６２との対面間隔（対向空間域）を、ビス６２３の螺合送り操作により近接（接近）離間調整することで、キャッチ部５２から対向空間域を介してマグネット部６２に流れる吸引磁気力の強弱（吸引磁力が接近するほど強く、遠ざけるほど弱くなる近接作用）を可変調整して設定できるようになっており、挿通孔６３１の内周域は、磁路としての機能と、その対面間隔を調整して吸着保持力を設定する調整域Ｓとしての機能を兼ね備えている。 Next, regarding the suction holding function of the magnet part 62 in a state where the catch part 52 is in contact with the contact part 63, a cross-sectional view of the main part showing the suction holding state between the catch part and the magnet part on the door end side in FIG. Based on As shown in this figure, when the catch portion 52 is brought into contact (contact) with the contact portion 63 that is the front peripheral surface area of the insertion hole 631 in a non-contact state in which the catch portion 52 is not in direct contact with the magnet portion 62, The inner peripheral area of the insertion hole 631 in which the magnetic pole (N pole) 622 is in a state in which the magnetic flux is induced functions as a magnetic path. By passing through this inner peripheral area, the leakage magnetic flux is reduced, and the catch portion 52 is instantly ringed. Thus, an even magnetic force is transmitted, and an efficient and stable magnetic field that flows to the magnet portion 62 (the surface of the S pole of the permanent magnet 621 ) through the opposing space is formed, thereby attracting the magnetic force. Face-to-face distance between the magnet unit 62 in a state in which the catching portion 52 has magnetic lifting the contact portion 63 (facing space area), closer by screwing feed operation for bis 623 (close) by spaced apart adjusting the catch portion 52 Can be variably adjusted to set the strength of the attractive magnetic force that flows to the magnet portion 62 via the opposing space region (proximity action that becomes stronger as the attractive magnetic force approaches and becomes weaker as it moves away). The inner peripheral area has both a function as a magnetic path and a function as an adjustment area S that adjusts the facing distance to set the suction holding force.
このように構成すると、本実施例における自閉式引戸１を全開位置と全閉位置で位置保持する際に、全開位置では、自閉装置３により引戸１が閉戸側に引っ張られる外力を受けているので、戸尻側のマグネット部６２と当接部６３との吸着保持力を、戸先側のものよりも強めに設定する必要がある場合に、両者の設定を異ならしめて調整することができ、さらには、鉄道車両に設置される引戸１（妻引戸）のように、人の乗り降りやカーブ走行等の際に、車体自身が揺れたり傾いたり、遠心力が加わるといった外力の影響を受けるものや、引戸１の移動ストローク、大きさや重量の異なるものであっても、設置される引戸１ごとにその対面間隔を調整域Ｓにより調整して最適な吸着保持力を設定することができ、引戸ごとに異なる磁力の永久磁石６２１を選定して、吸着保持力を設定製作する必要が回避される。 With this configuration, when the self-closing sliding door 1 according to the present embodiment is held in the fully open position and the fully closed position, in the fully open position, the self-closing device 3 receives an external force that pulls the sliding door 1 toward the closing door. because there, the suction holding force of the magnet portion 62 and the contact portion 63 of the door trailing side, if it is necessary to set stronger than that of the door leading end side, to adjust different et Shimete both settings In addition, like the sliding door 1 (Tsumari sliding door) installed on railway cars, the body itself is affected by external forces such as shaking and tilting and centrifugal force applied when getting on and off a person Even if the moving stroke, size and weight of the sliding door 1 are different, the facing distance between the sliding doors 1 to be installed can be adjusted by the adjustment area S to set the optimum suction holding force. Different permanent magnetic force for each sliding door And selecting the stone 621, it is avoided the need to set fabricate the suction holding force.
叙述の如く構成された本発明の実施の形態において、キャッチ手段５を、マグネット手段６の吸着磁力によって引戸１を全開または全閉位置で保持する位置保持するのであるが、本発明にかかる位置保持装置は、キャッチ手段５が、引戸１（吊り車２の吊り金具２１）または取付けベース１１に取着されるキャッチ取付け基板５１と、該キャッチ取付け基板５１に揺動可能に設けられ、マグネット手段６に対面当接するキャッチ部５２とで構成され、マグネット手段６は、引戸１（吊り金具２１）または取付けベース１１に取着されるマグネット取付け基板６１と、該マグネット取付け基板６１に、螺合送り操作によりその対向間隔を調整可能にキャッチ部５２に対面して設けられたマグネット部６２と、該マグネット部６２の外周を覆う挿通孔６３１を有し、挿通孔６３１の前周面に対してキャッチ部５２が当接される強磁性体にて形成される当接部６３とで構成され、当接部６３は、キャッチ部５２が当接した際に、マグネット部６２を非接触対面させた状態で、挿通孔６３１の内周域を、その内周面とマグネット部６２の外周面とを磁力伝達可能に配置せしめて磁路として機能させ、キャッチ部５２を吸着保持すると共に、この吸着状態で吸引磁力の強弱をビス６２３の螺合送り操作により調整して吸着保持力を設定可能な調整域Ｓとして機能すべく構成されている。 In the embodiment of the present invention configured as described above, the catch means 5 is held by the magnetic force of the magnet means 6 so that the sliding door 1 is held in the fully open or fully closed position. In the apparatus, the catch means 5 is provided on the sliding door 1 ( the hanging bracket 21 of the suspension vehicle 2 ) or the attachment base 11, and is provided on the catch attachment board 51 so as to be swingable. The magnet means 6 includes a magnet mounting board 61 attached to the sliding door 1 ( hanging bracket 21 ) or the mounting base 11, and a screw feed operation to the magnet mounting board 61. Covers the outer periphery of the magnet portion 62 and the magnet portion 62 provided facing the catch portion 52 so that the facing interval can be adjusted. The contact portion 63 is formed of a ferromagnetic body that has a through-hole 631 and the catch portion 52 is in contact with the front peripheral surface of the insertion hole 631. With the magnet part 62 facing non-contact when the 52 comes into contact, the inner peripheral area of the insertion hole 631 is arranged so that the inner peripheral surface and the outer peripheral face of the magnet part 62 can transmit magnetic force. It is configured to function as an adjustment area S in which the suction holding force can be set by adjusting the strength of the attractive magnetic force by screwing and feeding operation of the screw 623 in this attracted state. ing.
そのため、永久磁石６２１（マグネット）の吸着磁力を利用して引戸１を全開または全閉位置で位置保持するものでありながら、強磁性体にて形成される当接部６３の挿通孔６３１前周面にキャッチ部５２が当接した際、マグネット部６２の磁気力を、固定された磁路として機能する挿通孔６３１の内周域を通って、漏洩磁束を減少させ効率よく磁力伝達することができ、安定した磁界を形成し、キャッチ部５２を、マグネット部６２に直接当接させない非接触状態で、かつ揺動可能な状態で強固に吸着保持することができるだけでなく、永久磁石６２１の破損回避は勿論、閉戸時に戸先ゴムの弾性変形を受けても、キャッチ部５２が後方に揺動するので、面一に当接でき当接音の発生も抑止される。しかも、キャッチ部５２が当接部６３に磁力吸着した状態で、マグネット部６２との対面間隔を僅かな隙間に設定しても開閉に際して磁極短絡することがなく、精度良く近接離間する調整設定を行い得て、キャッチ部５２を介してマグネット部６２に流れる吸引磁気力の強弱を可変調整操作して、引戸１ごとに最適な吸着磁力をもって位置保持設定することができる。その結果、自閉式引戸１の戸先側と戸尻側の吸着保持力を異ならしめた設定や、開閉ストローク、大きさ、重量といった引戸１ごとに異なる吸着保持力を個々別々に設定することができ、その都度マグネットの磁気力を選定する必要もなく、一種類のマグネット手段６をもって適用の多様化と製作の一元化を図ることができると共に、車両用引戸の如く振動や傾動、遠心力といった外力の影響を受けても、これら外力に追随してキャッチ部５２が揺動し、吸着ズレが防止され面一な吸着状態が維持されて解離規制がなされ、引戸１を位置保持することができる。 Therefore, while the sliding door 1 is held in the fully open or fully closed position using the attractive magnetic force of the permanent magnet 621 (magnet), the front circumference of the insertion hole 631 of the contact portion 63 formed of a ferromagnetic material. when the catch portion 52 in contact with the surface, the magnetic force of the magnet portion 62, passes through the inner peripheral region of the insertion hole 631 functions as a fixed magnetic path to magnetic transmission rather by efficiently reducing the leakage flux It is possible not only to form a stable magnetic field, but to firmly attract and hold the catch portion 52 in a non-contact state in which the catch portion 52 is not in direct contact with the magnet portion 62 and in a swingable state. In addition to avoiding breakage, the catch portion 52 swings backward even when subjected to elastic deformation of the door-end rubber when the door is closed. In addition, even if the catch portion 52 is magnetically attracted to the contact portion 63, even if the facing distance from the magnet portion 62 is set to a slight gap, the magnetic pole is not short-circuited at the time of opening and closing, and the adjustment setting is performed so that the proximity and separation are performed with high accuracy. The position of the sliding door 1 can be set and maintained with an optimum attractive magnetic force by variably adjusting the strength of the attractive magnetic force flowing to the magnet portion 62 via the catch portion 52. As a result, it is possible to set different suction holding forces for each sliding door 1 such as opening / closing stroke, size, weight, etc. It is possible to diversify the application and unify production with one kind of magnet means 6 without having to select the magnetic force of the magnet each time, and external forces such as vibration, tilting and centrifugal force like a sliding door for vehicles. Even under the influence of the above, the catch portion 52 swings following these external forces, the adsorption displacement is prevented, the flush adsorption state is maintained, the dissociation is restricted, and the sliding door 1 can be held in position.
また、戸先側に配設されるマグネット手段６には、その上端部に、常時巻取方向に付勢されたワイヤー３１にて構成される自閉装置３が一体的に備えられている。この自閉装置３は、当接部６３を、挿通孔６３１の前周面に対して、キャッチ部５２が当接する当接面の上下にそれぞれ折曲せしめた取付け片６３２、６３２を有して正面視コ字状に形成すると共に、下側の取付け片６３２をマグネット取付け基板６１に取着し、上側の取付け片６３２に装着されている。
この様に構成すると、出荷時に予め自閉装置３の自閉力調整と、これに適合したマグネット手段６の組み合わせ調整させた基本的な設定製作が行え、部品点数の削減と製作の規格統一がなされ製作の煩雑化が解消されるだけでなく、引戸１への取付け作業時に自閉力の強弱調整の操作を行いながら、キャッチ部５２とマグネット部６２との対向離間調整や、キャッチ部５２と当接部６３との当接調整の設定を同時に行うことができ、作業効率の向上を図ることができる。
Further, the magnet means 6 disposed on the door end side is integrally provided with a self-closing device 3 composed of a wire 31 constantly biased in the winding direction at an upper end portion thereof. The self-closing device 3 includes mounting pieces 632 and 632 in which the contact portion 63 is bent above and below the contact surface with which the catch portion 52 contacts with the front peripheral surface of the insertion hole 631. The lower attachment piece 632 is attached to the magnet attachment substrate 61 and attached to the upper attachment piece 632 while being formed in a U-shape when viewed from the front.
With this configuration, it is possible to perform basic setting and production by adjusting the self-closing force of the self-closing device 3 in advance and adjusting the combination of the magnet means 6 suitable for this, reducing the number of parts and standardizing the production standards. This not only eliminates the complication of production, but also adjusts the opposing separation between the catch portion 52 and the magnet portion 62 while adjusting the strength of the self-closing force during the mounting operation to the sliding door 1, Setting of contact adjustment with the contact portion 63 can be performed at the same time, and work efficiency can be improved.
また、キャッチ部５２は、その中心に配設した支軸５２１にコイルスプリング５２２を装着した状態で、該支軸５２１の後端部を、キャッチ取付け基板５１に形成した軸孔５１３に遊嵌状に抜け止め挿入して、常時突出方向に弾発付勢せしめて支持し、当接部６３に磁力吸着した状態で、前後方向及び円周方向に揺動可能に構成されているので、当接部６３との面一な当接が図られ当接音の発生が抑止され、永久磁石６２１（マグネット）の破損回避は勿論、閉戸時の戸先ゴムの弾性変形や、地震等により、又は、車両用引戸の如く振動や傾動、遠心力といった外力の影響を受けても、吸着状態でこれら外力に追随してキャッチ部５２が揺動し、吸着ズレが防止され面一な吸着が維持され解離を規制することができる。 Further, the catch 52, while wearing the coil spring 522 to the support shaft 521 which is disposed at the center, loosely fitted to an end portion after the support shaft 521, the shaft hole 513 formed in the catch mounting substrate 51 It is configured to be able to swing in the front-rear direction and the circumferential direction in a state in which it is inserted into the stopper, supported by being always urged and urged in the protruding direction, and attracted to the contact part 63. The contact with the portion 63 is made even and the generation of the contact noise is suppressed, and the permanent magnet 621 (magnet) is prevented from being damaged, of course, due to elastic deformation of the door-end rubber at the time of closing, an earthquake, etc. Even if it is affected by external forces such as vibration, tilting, and centrifugal force as in a sliding door for a vehicle, the catch portion 52 swings following these external forces in the suction state, and the suction displacement is prevented and the flush suction is maintained. Dissociation can be regulated.
また、挿通孔６３１は、当接部６３を板状部材として円形に打ち抜き形成されると共に、キャッチ部５２は、挿通孔６３１の外径よりも大きな円板状に形成され、マグネット部６２は、キャッチ部５２の側面をＳ極面として背反するＮ極側をヨーク６２２内に収容された円盤状に形成され、ヨーク６２２の外周面が挿通孔６３１の内周面と僅かな隙間をもって又は接触した状態で磁力伝達可能に挿入されるよう構成される。
このように構成すると、キャッチ部５２を、マグネット部６２に直接当接させない非接触状態で、挿通孔６３１の前周面域となる当接部６３に当接（接触）した際、挿通孔６３１の内周域に対して、予めヨーク６２２の磁極（Ｎ極）が磁束誘導された状態とすることができ、この挿通孔６３１の内周域が磁路として機能し、この内周域を通ることで漏洩磁束を減少させ、瞬時にキャッチ部５２に環状で均等な磁力伝達がなされ、対向空間域を介してマグネット部６２（Ｓ極）へ流れる効率のよい安定した磁界形成によって磁力吸着させることができる。なお、キャッチ部５２、マグネット部６２、挿通孔６３１は円形に形成したが、角形であっても良く、その種類も選択できることは勿論である。
Further, the insertion hole 631 is formed in a circular shape with the contact portion 63 as a plate-like member, and the catch portion 52 is formed in a disk shape larger than the outer diameter of the insertion hole 631. The catch portion 52 is formed in a disc shape in which the side of the catch portion 52 is the S pole surface and the opposite N pole side is accommodated in the yoke 622, and the outer peripheral surface of the yoke 622 is in contact with or slightly in contact with the inner peripheral surface of the insertion hole 631 . It is configured to be inserted so that magnetic force can be transmitted in a state.
With this configuration, when the catch portion 52 is brought into contact (contact) with the contact portion 63 that is the front peripheral surface area of the insertion hole 631 in a non-contact state in which the catch portion 52 is not in direct contact with the magnet portion 62, the insertion hole 631. The magnetic pole (N pole) of the yoke 622 can be in a state in which the magnetic flux is induced in advance with respect to the inner circumferential area, and the inner circumferential area of the insertion hole 631 functions as a magnetic path and passes through the inner circumferential area. In this way, the magnetic flux leakage is reduced, and an even and uniform magnetic force is transmitted to the catch portion 52 instantly, and the magnetic force is attracted by the efficient and stable magnetic field formation that flows to the magnet portion 62 (S pole) through the opposed space area. Can do. In addition, although the catch part 52, the magnet part 62, and the insertion hole 631 were formed circularly, of course, it may be a square and the kind can also be selected.
永久磁石６２１（マグネット）の吸着磁力を利用して引戸１を全開または全閉位置で位置保持するものでありながら、キャッチ部５２を、マグネット部６２とは非接触状態で当接部６３の挿通孔６３１の前周面域に当接できるようにし、その当接時に、マグネット部６２の磁気力を、挿通孔６３１の内周域を磁路として磁力伝達させ、挿通孔６３１の前周面に揺動可能な状態で磁力吸着させて引戸１を位置保持できるようにすると共に、吸着状態でマグネット部６２との対面間隔を近接離間する調整操作を行い得て、キャッチ部５２を介してマグネット部６２に流れる吸引磁気力の強弱の可変調整を可能とし、引戸装置に最適な吸着保持力を設定できるようにして、一種類のマグネット手段６をもって開閉ストローク、大きさ、重量の異なる種々の引戸１に適用することができる。
While the sliding door 1 is held in the fully open or fully closed position using the attractive magnetic force of the permanent magnet 621 (magnet), the catch portion 52 is inserted into the contact portion 63 in a non-contact state with the magnet portion 62. It is possible to contact the front peripheral surface area of the hole 631, and at the time of the contact, the magnetic force of the magnet portion 62 is transmitted as a magnetic path using the inner peripheral area of the insertion hole 631 as a magnetic path, to the front peripheral surface of the insertion hole 631. The sliding door 1 can be held in position by being magnetically attracted in a swingable state, and an adjustment operation can be performed to bring the facing distance from the magnet portion 62 close to each other in the attracted state. 62. It is possible to variably adjust the strength of the attractive magnetic force flowing to 62, and to set an optimum suction holding force for the sliding door device, so that the opening / closing stroke, size, and weight are different with one kind of magnet means 6. It can be applied to the sliding door 1 of the people.
