Description

本発明は、引き戸等の開閉動作の緩衝等に利用される緩衝装置に関する。   The present invention relates to a shock absorber used for buffering an opening / closing operation of a sliding door or the like.

従来、家屋の引き戸等の開閉動作を緩衝する装置では、自動的な引き込み装置に、油圧を利用した直線ダンパや回転ダンパを選択して組み合わせたものがある。かかる装置では、例えば、引き戸が閉まる手前でスプリングを利用した引き込み装置が作用すると共に直線ダンパや回転ダンパにより減衰し、自動引き込み及び緩衝を行わせることができる。   2. Description of the Related Art Conventionally, some devices that cushion opening and closing operations such as a sliding door in a house include a combination of an automatic pull-in device that is selected and combined with a linear damper or a rotary damper using hydraulic pressure. In such a device, for example, a pull-in device using a spring acts before the sliding door closes, and it is attenuated by a linear damper or a rotary damper to allow automatic pull-in and buffering.

[Mounting and retracting to the movable unit]
2A and 2B are diagrams for explaining the operation of the shock absorber. FIG. 2A shows a state before the collision with the fixed side, FIG. 2B shows the start of the collision, FIG. 2C shows the drawing, FIG. 2D shows the drawing back, and FIG. These are explanatory drawings which show engagement return.

（ａ）緩衝装置１は、直線移動する可動側ユニットに取り付けられ、固定側ユニット５９の凸部６１に対し可動側ユニットと共に直線移動する。このとき、ピン３３，３７が係止ガイド孔２７、２９に至って係合保持されており、ピン３１、３５を中心に回転して傾斜状態であり、可動駒体９（１１）の係合凹部１３（１５）が進行方向に指向傾斜している。   (A) The shock absorber 1 is attached to a movable unit that moves linearly, and moves linearly together with the movable unit with respect to the convex portion 61 of the fixed unit 59. At this time, the pins 33 and 37 are engaged and held so as to reach the locking guide holes 27 and 29, are rotated around the pins 31 and 35, and are in an inclined state, and the engaging concave portion of the movable piece body 9 (11). 13 (15) is directed and inclined in the traveling direction.

（ｂ）可動側ユニットの移動により緩衝装置１の傾斜した係合凹部１３が凸部６１に衝突すると、可動駒体９が凸部６１から抵抗を受けて直線ガイド孔２３に沿った移動力を受ける。このとき可動駒体９は、ピン３１回りに回転し、ピン３３が係止ガイド孔２７から外れてピン３１、３３が共にガイド部５の直線ガイド孔２３でのガイド状態となる。   (B) When the engaging concave portion 13 inclined of the shock absorber 1 collides with the convex portion 61 due to the movement of the movable side unit, the movable piece body 9 receives resistance from the convex portion 61 and applies a moving force along the straight guide hole 23. receive. At this time, the movable piece body 9 rotates around the pin 31, the pin 33 is removed from the locking guide hole 27, and both the pins 31 and 33 are in the guide state in the linear guide hole 23 of the guide portion 5.

（ｃ）ピン３１、３３がガイド部５の直線ガイド孔２３でのガイド状態になると、可動駒体９がガイド部５の直線ガイド孔２３に沿って直線移動可能となり、凸部６１から可動駒体９が受けた衝突力が、可動駒体９の直線移動により嵌合部４１、結合体５５、ロッド１９ａを介して直線ダンパ１９で受けられる。   (C) When the pins 31 and 33 are in the guide state in the straight guide hole 23 of the guide portion 5, the movable piece body 9 can be linearly moved along the straight guide hole 23 of the guide portion 5. The collision force received by the body 9 is received by the linear damper 19 through the fitting portion 41, the coupling body 55, and the rod 19a by the linear movement of the movable piece body 9.

このとき、シリンダ１９ｂ側の結合体５７から可動駒体１１の嵌合部４５に力が伝達されると、ピン３７から係止ガイド孔２９に力が伝達され、可動駒体１１は、そのままの姿勢を維持する。   At this time, when a force is transmitted from the coupling body 57 on the cylinder 19b side to the fitting portion 45 of the movable piece body 11, a force is transmitted from the pin 37 to the locking guide hole 29, and the movable piece body 11 remains as it is. Maintain posture.

衝突力を受けた直線ダンパ１９は、可動駒体９の移動に伴って衝突力を吸収し、同時にばね１７から結合体５１、５３を介し可動駒体９が可動駒体１１方向へ引っ張り力を受ける。   The linear damper 19 that receives the collision force absorbs the collision force as the movable piece body 9 moves, and at the same time, the movable piece body 9 pulls the pulling force in the direction of the movable piece body 11 from the spring 17 via the coupling bodies 51 and 53. receive.

この引っ張り力で、直線ダンパ１９の抵抗を受けながら可動駒体９が直線ガイド孔２３をその端部まで静かに移動し、引き込まれる。   With this pulling force, the movable piece body 9 gently moves to the end of the straight guide hole 23 and is pulled in while receiving the resistance of the straight damper 19.

（ｄ）可動側ユニットが逆方向へ移動すると、凸部６１に係合している可動駒体９はそのままの位置を維持するから、ベース３側の移動により可動駒体９が直線ガイド孔２３の係止ガイド孔２７側へ相対移動する。この相対移動で、ばね１７及び直線ダンパ１９は伸長する。   (D) When the movable side unit moves in the opposite direction, the movable piece body 9 engaged with the convex portion 61 maintains the position as it is, so that the movable piece body 9 is moved to the linear guide hole 23 by the movement on the base 3 side. Relative to the locking guide hole 27 side. By this relative movement, the spring 17 and the linear damper 19 are extended.

（ｅ）可動側ユニットが逆方向へさらに移動すると、ピン３３が遷移部２７ａを経て係止ガイド孔２７へ移行し、可動駒体９がピン３１を中心に回転し、傾斜して係合保持される。   (E) When the movable side unit further moves in the reverse direction, the pin 33 moves to the locking guide hole 27 via the transition portion 27a, and the movable piece body 9 rotates around the pin 31 and tilts and holds the engagement. Is done.

この可動駒体９の傾斜により係合凹部１３が凸部６１から外れ、可動側ユニットはフリーに移動可能となる。   Due to the inclination of the movable piece body 9, the engaging concave portion 13 is detached from the convex portion 61, and the movable side unit can move freely.

（ａ）〜（ｅ）までの動作は、可動駒体１１側においても、逆方向への移動で図示しない凸部との関係により同様に行われる。
［引き戸への取り付け］
図３〜図７は、引き戸に装着したドア引き込みユニットの動作説明図である。なお、図３〜図７では、ドア引き込みユニットを拡大して関連図示している。 The operations from (a) to (e) are similarly performed on the movable piece body 11 side due to the movement in the reverse direction and the relationship with the projection not shown.
[Mounting on sliding doors]
3-7 is explanatory drawing of operation | movement of the door drawing-in unit with which the sliding door was mounted | worn. In addition, in FIGS. 3-7, the door drawing-in unit is expanded and related drawing is shown.

図３〜図７のように、固定側である家屋の開口部６３に、可動側である引き戸６５が組み付けられ、引き戸６５を開口部６３に対しスライド移動させることで開口部６３を開閉可能となっている。   As shown in FIGS. 3 to 7, the sliding door 65 on the movable side is assembled to the opening 63 of the house on the fixed side, and the opening 63 can be opened and closed by sliding the sliding door 65 with respect to the opening 63. It has become.

開口部６３には、固定側のスライド・レールが取り付けられ、このスライド・レールに引き戸６５が直線移動可能に支持されている。開口部１には、固定側の凸部６１ａ，６１ｂが引き戸６５の全開位置及び全閉位置に対応して設けられている。引き戸６５には、前記緩衝装置１で構成されたドア引き込みユニット６７が取り付けられている。   A fixed slide rail is attached to the opening 63, and a sliding door 65 is supported on the slide rail so as to be linearly movable.

[Mounting and retracting to the movable unit]
FIG. 14 is an explanatory diagram of the operation of the shock absorber, (a) before the collision with the fixed side, (b) the start of the collision, (c) withdraw, (d) withdraw, (e) These are explanatory drawings which show engagement return.

図１４の（ａ）〜（ｅ）の動作は、実施例１の図２の（ａ）〜（ｅ）の動作に対応している。なお、図１４にない符号は、図１１〜図１３を参照する。   The operations in FIGS. 14A to 14E correspond to the operations in FIGS. 2A to 2E in the first embodiment. Reference numerals not shown in FIG. 14 refer to FIGS.

（ａ）緩衝装置１Ａは、直線移動する可動側ユニットに取り付けられ、固定側ユニット５９Ａの磁性体の衝突部６１Ａに対し可動側ユニットと共に直線移動する。このとき、可動駒体９Ａ、１１Ａのチェック体３３Ａａ、３７Ａａが段差部２７Ａ、２９Ａにチェックスプリング３３Ａｂ、３７Ａｂの付勢力を介して係合保持されている。   (A) The shock absorber 1A is attached to a movable unit that moves linearly, and moves linearly together with the movable unit relative to the magnetic collision portion 61A of the fixed unit 59A. At this time, the check bodies 33Aa and 37Aa of the movable piece bodies 9A and 11A are engaged and held by the step portions 27A and 29A through the urging force of the check springs 33Ab and 37Ab.

（ｂ）可動側ユニットの移動により緩衝装置１Ａの係合凸部１３Ａが衝突部６１Ａに衝突すると、可動駒体９Ａが衝突部６１Ａから抵抗を受けて直線ガイド孔２３Ａに沿った移動力を受ける。このとき可動駒体９Ａのチェック体３３Ａａがチェックスプリング３３Ａｂの付勢力に抗して退避することにより段差部２７Ａから外れ、底板３Ａｄ上を摺動可能となる。   (B) When the engaging convex portion 13A of the shock absorber 1A collides with the collision portion 61A due to the movement of the movable side unit, the movable piece body 9A receives resistance from the collision portion 61A and receives a moving force along the linear guide hole 23A. . At this time, the check body 33Aa of the movable piece body 9A is retracted against the urging force of the check spring 33Ab, so that it is detached from the stepped portion 27A and can slide on the bottom plate 3Ad.

（ｃ）チェック体３３Ａａが段差部２７Ａから外れると、可動駒体９Ａが直線ガイド孔２３Ａに沿って直線移動可能となり、衝突部６１Ａから可動駒体９が受けた衝突力が、可動駒体９Ａの直線移動により直線ダンパ１９Ａで受けられる。   (C) When the check body 33Aa is disengaged from the step portion 27A, the movable piece body 9A can move linearly along the straight guide hole 23A, and the collision force received by the movable piece body 9 from the collision portion 61A is the movable piece body 9A. Is received by the linear damper 19A.

衝突力を受けた直線ダンパ１９Ａは、可動駒体９Ａの移動に伴って衝突力を吸収し、同時にばね１７Ａから可動駒体９Ａが可動駒体１１Ａ方向へ引っ張り力を受ける。   The linear damper 19A receiving the collision force absorbs the collision force as the movable piece body 9A moves, and at the same time, the movable piece body 9A receives a pulling force in the direction of the movable piece body 11A from the spring 17A.

この引っ張り力で、直線ダンパ１９Ａの減衰を受けながら可動駒体９Ａが直線ガイド孔２３Ａをその端部まで静かに移動し、引き込み力を出す。このとき、直線ガイド孔２３Ａの端部は、引き込み時のストッパを兼ねる。直線ガイド孔２５Ａの端部も同様に可動駒体１１Ａ引き込み時のストッパを兼ねる。   With this pulling force, the movable piece body 9A gently moves to the end portion of the straight guide hole 23A while receiving the attenuation of the straight damper 19A, and generates a pulling force. At this time, the end portion of the straight guide hole 23A also serves as a stopper when retracted. Similarly, the end portion of the linear guide hole 25A also serves as a stopper when the movable piece body 11A is retracted.

（ｄ）可動側ユニットが逆方向へ移動すると、衝突部６１Ａに磁着している可動駒体９Ａはそのままの位置を維持するから、ベース３Ａ側の移動により可動駒体９Ａがブラケット３Ａｅ側へ相対移動する。この相対移動で、ばね１７Ａ及び直線ダンパ１９Ａは伸長する。   (D) When the movable side unit moves in the reverse direction, the movable piece body 9A magnetically attached to the collision part 61A maintains its position, so that the movable piece body 9A moves toward the bracket 3Ae by moving the base 3A side. Move relative. With this relative movement, the spring 17A and the linear damper 19A extend.

（ｅ）可動側ユニットが逆方向へさらに移動すると、可動駒体９Ａがブラケット３Ａｅに当接し、チェック体３３Ａａが段差部２７Ａにチェックスプリング３３Ａｂの付勢力により落ち込み、係合保持される。   (E) When the movable unit further moves in the reverse direction, the movable piece body 9A comes into contact with the bracket 3Ae, and the check body 33Aa falls into the stepped portion 27A by the urging force of the check spring 33Ab and is held in engagement.

この可動駒体９Ａの係合保持により係合凸部１３Ａが衝突部６１Ａから離脱し、可動側ユニットはフリーに移動可能となる。   By engaging and holding the movable piece body 9A, the engaging convex portion 13A is detached from the collision portion 61A, and the movable side unit can move freely.

（ａ）〜（ｅ）までの動作は、可動駒体１１Ａ側においても、逆方向への移動で図示しない衝突部との関係により同様に行われる。   The operations from (a) to (e) are similarly performed on the movable piece body 11A side due to the movement in the reverse direction and the relationship with the collision unit (not shown).

したがって、本実施例も図３〜図７同様に、開口部の引き戸に適用することができ、同様の作用効果を奏することができる。また、ベース３Ａが閉じ断面構造であり、直線ダンパ１９Ａから液漏れがあっても、外部への流出を規制することができる。   Therefore, this embodiment can also be applied to the sliding door of the opening as in FIGS. 3 to 7, and the same effects can be obtained. Further, the base 3A has a closed cross-sectional structure, and even if there is a liquid leak from the linear damper 19A, the outflow to the outside can be regulated.

なお、本実施例２の緩衝装置１Ａも、図８〜図１０のように、固定側である固定側ユニット５９Ａに取り付け、磁性体の衝突部６１Ａを可動側ユニットに形成することもできる。   The shock absorber 1A according to the second embodiment can also be attached to the fixed side unit 59A that is the fixed side, and the magnetic collision portion 61A can be formed on the movable side unit, as shown in FIGS.
