Description

本発明は、家屋の開口部に取り付けられる引き戸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 attached to an opening of a house.

従来、家屋の引き戸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緩衝し、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, there is a device for buffering the opening / closing operation of a sliding door of a house, in which an automatic pulling device is selected and combined with a linear damper or a rotary damper using hydraulic pressure. In such a device, for example, a retracting device using a spring acts before the sliding door closes, and it can be buffered by a linear damper or a rotary damper to perform automatic retracting and buffering.

この場合、ダンピング作用を比較的強く設定すれば、スプリングを強めにして早い引き込みに対しても充分に緩衝させることができる。   In this case, if the damping action is set to be relatively strong, the spring can be strengthened so that it can be sufficiently buffered against rapid pull-in.

しかし、スプリング力を弱く設定した場合には、ダンピング作用が過剰となり、引き込み速度が遅くなるという問題がある。   However, when the spring force is set weak, there is a problem that the damping action becomes excessive and the pull-in speed becomes slow.

すなわち、直線ダンパや回転ダンパの何れか単一の緩衝体を用いる場合、その緩衝作用の設定により引き戸、すなわち可動側の可動特性が一義的に決定されてしまうことになる。   That is, when any one of the linear damper and the rotary damper is used, the sliding door, that is, the movable characteristic on the movable side is uniquely determined by the setting of the buffer action.

特開２００５−２３０４６８号公報JP 2005-230468 A

解決しようとする問題点は、単一の緩衝体の緩衝作用の設定により可動側の可動特性が一義的に決定される点である。   The problem to be solved is that the movable characteristic on the movable side is uniquely determined by setting the buffer action of a single buffer.

本発明は、可動側の可動特性の設定範囲を拡げるため、固定側又は可動側の一方に係合しつつ他方に対し相対移動可能に支持された第１，第２の可動体と、固定側又は可動側の他方と前記第１，第２の可動体との間に設けられ第１，第２の可動体の移動を緩衝する第１，第２の緩衝体と、第１，第２の可動体の一方の移動途中で他方が前記固定側又は可動側の一方から係合が外れることを最も主要な特徴とする。 In order to expand the movable characteristic setting range on the movable side, the present invention includes first and second movable bodies that are engaged with one of the fixed side or the movable side and supported relative to the other, and the fixed side. Alternatively, the first and second buffer bodies provided between the other movable side and the first and second movable bodies to buffer the movement of the first and second movable bodies, and the first and second The main feature is that the engagement of one of the movable body and the other is disengaged from one of the fixed side and the movable side.

本発明の緩衝装置は、固定側又は可動側の一方に係合しつつ他方に対し相対移動可能に支持された第１，第２の可動体と、固定側又は可動側の他方と前記第１，第２の可動体との間に設けられ第１，第２の可動体の移動を緩衝する第１，第２の緩衝体と、第１，第２の可動体の一方の移動途中で他方が前記固定側又は可動側の一方から係合が外れるため、第１，第２の緩衝体の一方の作用を途中で停止させることができる。このため、可動側の可動特性を、第１，第２の緩衝体が共に作用する状態と一方のみ作用する状態とに変化させることができ、第１，第２の緩衝体の緩衝特性の設定により、可動特性の設定範囲を拡げることができる。 The shock absorber according to the present invention includes a first movable body and a second movable body that are engaged with one of the fixed side and the movable side and supported relative to the other, the other of the fixed side and the movable side, and the first. The first and second buffer bodies provided between the second movable body and buffering the movement of the first and second movable bodies, and the other in the middle of the movement of one of the first and second movable bodies However, since the engagement is released from one of the fixed side and the movable side, the operation of one of the first and second buffer bodies can be stopped halfway. For this reason, the movable characteristic on the movable side can be changed between a state where the first and second buffer bodies act together and a state where only one acts, and setting of the buffer characteristics of the first and second buffer bodies. As a result, the movable characteristic setting range can be expanded.

可動側の可動特性の設定範囲を拡げるという目的を、複数の緩衝体を用いることで実現した。   The purpose of expanding the movable characteristic setting range on the movable side was realized by using a plurality of shock absorbers.

［緩衝動作］
引き戸を図２（ａ）の解放状態から閉めると、全閉状態の少し手前で、（ｂ）のようにドア・クローザー引き込みユニット７が引き戸３の引き込みを開始し、（ｃ）のように全閉状態まで緩衝しつつ自動で閉じる。 [Buffer operation]
When the sliding door is closed from the released state in FIG. 2 (a), the door / closer pulling unit 7 starts to pull in the sliding door 3 as shown in (b) just before the fully closed state, and as shown in (c). It closes automatically while buffering to the closed state.

図２（ａ）の解放状態から閉めるときは、インナー・レール１３がガイド・レール１１にガイドされつつ鋼球１６の転動を介しアウター・レール９に沿って全閉方向へ直線移動する。   When closing from the released state of FIG. 2A, the inner rail 13 is linearly moved along the outer rail 9 in the fully closed direction via the rolling of the steel balls 16 while being guided by the guide rail 11.

前記引き込みを開始時は、図８（ａ）、図９（ａ）のように、インナー・レール１３の連結バー１７が、第１，第２の連結板２１ａ，２３ａの連結爪部５７，６１に当接する。この当接により第１，第２の連結板２１ａ，２３ａが第２，第４のピン６７，６９を中心に回転力を受け、第１，第２の連結板２１ａ，２１ｂ，２３ａ，２３ｂの相対移動開始時に第１，第２のピン６３，６５が退避部４９，５３から外れ、ロックが解除される。   At the start of the retraction, as shown in FIGS. 8A and 9A, the connecting bar 17 of the inner rail 13 is connected to the connecting claws 57 and 61 of the first and second connecting plates 21a and 23a. Abut. By this contact, the first and second connecting plates 21a, 23a receive a rotational force around the second and fourth pins 67, 69, and the first and second connecting plates 21a, 21b, 23a, 23b At the start of relative movement, the first and second pins 63 and 65 are disengaged from the retracting portions 49 and 53, and the lock is released.

このロック解除により第１，第２コイル・スプリング２９，３１が働き、双方の付勢力により第１，第２の連結板２１ａ，２１ｂ，２３ａ，２３ｂが、直線的に相対移動する。このとき、第１のガイド長孔４５，４７に第１，第３のピン６３，６７、第２，第４のピン６５，６９がそれぞれガイドされる。   By releasing the lock, the first and second coil springs 29 and 31 work, and the first and second connecting plates 21a, 21b, 23a and 23b move relatively linearly by the urging force of both. At this time, the first and third pins 63 and 67 and the second and fourth pins 65 and 69 are guided in the first guide long holes 45 and 47, respectively.

この直線的な相対移動により第１，第２の連結板２１ａ，２３ａの連結爪部５５，５９が連結バー１７に係合し、連結バー１７を第１，第２の連結板２１ａ，２１ｂ，２３ａ，２３ｂによって直線的に引き込み、相対移動させる。   By this linear relative movement, the connecting claw portions 55 and 59 of the first and second connecting plates 21a and 23a are engaged with the connecting bar 17, and the connecting bar 17 is connected to the first and second connecting plates 21a, 21b, 23a and 23b are linearly drawn and moved relative to each other.

この連結バー１７の相対移動によりインナー・レール１３が第１，第２コイル・スプリング２９，３１の付勢力を受けながらスライド移動して引き戸３の引き込みが行われる。   By the relative movement of the connecting bar 17, the inner rail 13 slides while receiving the urging force of the first and second coil springs 29, 31, and the sliding door 3 is retracted.

この引き込み時に、直線ダンパ２５側ではピストンが動作し、回転ダンパ２７側では、ラック部材７５の移動によりラック７７に噛み合うピニオン７３が回転する。ピストンの動作及びピニオン７３の回転により直線ダンパ２５及び回転ダンパ２７がダンピング作用を奏する。   At this time, the piston operates on the linear damper 25 side, and on the rotary damper 27 side, the pinion 73 engaged with the rack 77 is rotated by the movement of the rack member 75. The linear damper 25 and the rotary damper 27 perform a damping action by the operation of the piston and the rotation of the pinion 73.

前記第２の連結板２３ａ，２３ｂの移動途中で第１の連結板２１ａ，２１ｂ間の第３のピン６７が第１のガイド長孔４５の退避部５１にガイドされて退避し、第１の連結板２１ａ，２１ｂが第１のピン６３を中心に回動する。この回動により第１の連結板２１ａの連結爪部５７が連結バー１７から外れる。   During the movement of the second connecting plates 23a and 23b, the third pin 67 between the first connecting plates 21a and 21b is guided and retracted by the retracting portion 51 of the first guide long hole 45, so that the first The connecting plates 21a and 21b rotate around the first pin 63. By this rotation, the connection claw portion 57 of the first connection plate 21 a is detached from the connection bar 17.

従って、第１のコイル・スプリング２９の付勢力の作用及び直線ダンパ２５の作用は無くなる。   Accordingly, the action of the urging force of the first coil spring 29 and the action of the linear damper 25 are eliminated.

前記第２の連結板２３ａの連結爪部６１による連結は維持されるから、第２のコイル・スプリング３１の付勢による引き込みは継続され、回転ダンパ２７のみによるダンピングが行われる。   Since the connection of the second connection plate 23a by the connection claw portion 61 is maintained, the retraction by the urging of the second coil spring 31 is continued, and the damping is performed only by the rotary damper 27.

従って、引き戸３は、自動で引き込まれながら図２（ｃ）の全閉状態となる。   Therefore, the sliding door 3 is fully closed as shown in FIG.

前記引き戸３を全閉状態から開けると、引き戸３と共に移動するインナー・レール１３の連結バー１７が第２の連結板２３ａの連結爪部５９に係合し、第２の連結板２３ａ，２３ｂを上記とは逆方向へ第２のガイド長孔４７に沿って連動させる。   When the sliding door 3 is opened from the fully closed state, the connecting bar 17 of the inner rail 13 that moves together with the sliding door 3 engages with the connecting claw portion 59 of the second connecting plate 23a, and the second connecting plates 23a and 23b are engaged. The second guide slot 47 is interlocked in the opposite direction to the above.

従って、引き戸３３の開き始めは、第２のコイル・スプリング３１の付勢力及び回転ダンパ２７のダンピング力のみが引き戸を開く操作力に対し反力として働き、第１のコイル・スプリング２９の付勢力及び直線ダンパ２５のダンピング力は働かない。なお、回転ダンパ２７を一方向性のものにすると、引き戸３を開くときは、ダンピング力が働かないようにすることもできる。   Accordingly, when the sliding door 33 starts to open, only the urging force of the second coil spring 31 and the damping force of the rotary damper 27 act as reaction forces against the operating force to open the sliding door, and the urging force of the first coil spring 29. And the damping force of the linear damper 25 does not work. If the rotary damper 27 is unidirectional, the damping force can be prevented from acting when the sliding door 3 is opened.

前記第２の連結板２３ａ，２３ｂの移動途中で、前記連結バー１７が第１の連結板２１ａの連結爪部５５に係合し、第１の連結板２１ａ，２１ｂを上記とは逆方向へ第１のガイド長孔４５に沿って連動させる。   During the movement of the second connecting plates 23a and 23b, the connecting bar 17 engages with the connecting claw portion 55 of the first connecting plate 21a, and the first connecting plates 21a and 21b are moved in the opposite direction. The first guide slot 45 is interlocked.

前記第１，第２の連結板２１ａ，２１ｂ，２３ａ，２３ｂが共に移動し、相対移動開始位置へ復帰するとき、第１，第２のピン６３，６５が、第１，第２のガイド長孔４５，４７の退避部４９，５３にガイドされて退避する。この退避により、第１，第２の連結板２１ａ，２１ｂ，２３ａ，２３ｂが第３，第４のピン６７，６９を中心に回動し、第１，第２のピン６３，６５が再ロックされると共に連結バー１７が連結爪部５５，５９から外れる。   When the first and second connecting plates 21a, 21b, 23a, and 23b move together and return to the relative movement start position, the first and second pins 63 and 65 become the first and second guide lengths. It is guided and retracted by the retracting portions 49 and 53 of the holes 45 and 47. By this retraction, the first and second connecting plates 21a, 21b, 23a, and 23b rotate around the third and fourth pins 67 and 69, and the first and second pins 63 and 65 are re-locked. At the same time, the connecting bar 17 is detached from the connecting claw portions 55 and 59.

従って、引き戸３がドア・クローザー引き込みユニット７から解放され、直線ダンパ２５，回転ダンパ２７及び第１，第２コイル・スプリング２９，３１の反力が無い状態で開き動作させることができる。   Accordingly, the sliding door 3 is released from the door closer retracting unit 7 and can be opened without the reaction force of the linear damper 25, the rotary damper 27, and the first and second coil springs 29, 31.

［実施例１の効果］
本発明実施例のドア・クローザー引き込みユニット７は、インナー・レール１３の連結バー１７に係合しつつ開口部１に取り付けられたハウジング１９に対し相対移動可能に支持された第１，第２の連結板２１ａ，２１ｂ，２３ａ，２３ｂと、ハウジング１９と第１，第２の連結板２１ａ，２１ｂ，２３ａ，２３ｂとの間に設けられ第１，第２の連結板２１ａ，２１ｂ，２３ａ，２３ｂの移動を緩衝する直線ダンパ２５，回転ダンパ２７と、第１，第２の連結板２１ａ，２１ｂ，２３ａ，２３ｂの移動途中で第２の連結板２３ａ，２３ｂがインナー・レール１３側の連結バー１７から外れるため、直線ダンパ２５の作用を途中で停止させることができる。このため、インナー・レール１３の可動特性を、直線ダンパ２５及び回転ダンパ２７が共に作用する状態と回転ダンパ２７のみ作用する状態とに変化させることができ、直線ダンパ２５及び回転ダンパ２７の緩衝特性の設定により、インナー・レール１３の可動特性の設定範囲を拡げることができる。 [Effect of Example 1]
The door / closer retracting unit 7 according to the embodiment of the present invention is engaged with the connecting bar 17 of the inner rail 13 while being supported so as to be movable relative to the housing 19 attached to the opening 1. First and second connection plates 21a, 21b, 23a, and 23b provided between the connection plates 21a, 21b, 23a, and 23b, and the housing 19 and the first and second connection plates 21a, 21b, 23a, and 23b. In the middle of the movement of the linear damper 25, the rotary damper 27, and the first and second connecting plates 21a, 21b, 23a, and 23b, the second connecting plates 23a and 23b are connected to the inner rail 13 side. Therefore, the action of the linear damper 25 can be stopped halfway. For this reason, the movable characteristic of the inner rail 13 can be changed between a state where the linear damper 25 and the rotary damper 27 act together and a state where only the rotary damper 27 acts, and the buffer characteristic of the linear damper 25 and the rotary damper 27. With this setting, the setting range of the movable characteristic of the inner rail 13 can be expanded.

すなわち、引き戸３の引き込み始めは、第１，第２のコイル・スプリング２９，３１の双方による付勢力で早く引き込み且つ直線ダンパ２５及び回転ダンパ２７によりダンピングさせ、引き込み途中から第２のコイル・スプリング３１のみにより遅い速度で引き込み且つ回転ダンパ２７によりダンピングさせる。   That is, when the sliding door 3 starts to be retracted, it is quickly retracted by the urging force of both the first and second coil springs 29 and 31, and is damped by the linear damper 25 and the rotary damper 27. Only 31 is pulled in at a slower speed and is damped by the rotary damper 27.

このような、引き込み動作により、引き戸３を迅速且つ穏やかに引き込むことが可能となる。   Such a pull-in operation makes it possible to pull the sliding door 3 quickly and gently.

この引き戸３を開くときは、始めに前記のように第２のコイル・スプリング３１の付勢力及び回転ダンパ２７のダンピング力のみが操作力に対し反力として働くが、第１のコイル・スプリング２９の付勢力及び直線ダンパ２５のダンピング力は働かないため、操作力が重くなることもない。また、引き戸３が開き始めれば、慣性力の働きにより途中から第１，第２のコイル・スプリング２９，３１の双方の反力及び直線ダンパ２５及び回転ダンパ２７のダンピング力が共に働いても、特に操作力が重くなる感じはなく、引き戸３を円滑に開くことができる。但し、回転ダンパ２７及び直線ダンパ２５を一方向性のものにすれば、引き戸３を開くときは、双方のダンピング力が共に発生しないようにすることもできる。   When the sliding door 3 is opened, only the urging force of the second coil spring 31 and the damping force of the rotary damper 27 are acted as reaction forces against the operating force as described above, but the first coil spring 29 Since the urging force and the damping force of the linear damper 25 do not work, the operating force does not increase. Further, if the sliding door 3 starts to open, even if the reaction force of both the first and second coil springs 29 and 31 and the damping force of the linear damper 25 and the rotary damper 27 work together in the middle due to the action of inertial force, In particular, there is no feeling that the operation force becomes heavy, and the sliding door 3 can be opened smoothly. However, if the rotary damper 27 and the linear damper 25 are unidirectional, it is possible to prevent both damping forces from being generated when the sliding door 3 is opened.

前記ハウジング１９に、前記第１，第２の連結板２１ａ，２１ｂ，２３ａ，２３ｂの相対移動をガイドする第１，第２のガイド長孔４５，４７を設け、前記第１，第２のガイド長孔４５，４７部は、前記第１，第２の連結板２１ａ，２３ａの前記相対移動開始時に前記インナー・レール１３の連結バー１７に係合を開始すると共に相対移動開始位置への復帰時に係合が外れるように前記ガイドを行うため、インナー・レール１３の相対移動により直線ダンパ２５及び回転ダンパ２７の作用を開始及び停止させることができる。   The housing 19 is provided with first and second guide long holes 45 and 47 for guiding relative movement of the first and second connecting plates 21a, 21b, 23a and 23b, and the first and second guides are provided. The long holes 45 and 47 start engaging with the connecting bar 17 of the inner rail 13 at the start of the relative movement of the first and second connecting plates 21a and 23a and return to the relative movement start position. Since the guide is performed so that the engagement is disengaged, the actions of the linear damper 25 and the rotary damper 27 can be started and stopped by the relative movement of the inner rail 13.

前記第１，第２の連結板２１ａ，２１ｂ，２３ａ，２３ｂの前記相対移動を付勢する第１，第２のコイル・スプリング２９，３１を設け、前記第１，第２のガイド長孔４５，４７は、前記第１，第２の連結板２１ａ，２１ｂ，２３ａ，２３ｂの相対移動の開始位置で前記第１，第２のコイル・スプリング２９，３１による付勢移動をロックすると共に前記第１，第２の連結板２１ａ，２１ｂ，２３ａ，２３ｂの前記相対移動開始時に前記ロックを外し且つ相対移動の開始位置への復帰時に再ロックするように前記ガイドを行うため、インナー・レール１３の移動によりロックを外して第１，第２のコイル・スプリング２９，３１を作用させインナー・レール１３の相対移動を第１，第２のコイル・スプリング２９，３１により自動で行わせ、再ロックにより次の相対移動に備えさせることができる。   The first and second guide elongated holes 45 are provided with first and second coil springs 29 and 31 for urging the relative movement of the first and second connecting plates 21a, 21b, 23a and 23b. , 47 lock the urging movement by the first and second coil springs 29, 31 at the relative movement start position of the first and second connecting plates 21a, 21b, 23a, 23b and the first. In order to perform the guide so that the lock is released when the relative movement of the first and second connecting plates 21a, 21b, 23a, and 23b is started and the second connection plates 21a, 21b, 23a, and 23b are returned to the relative movement start position, The first and second coil springs 29 and 31 are actuated by unlocking the movement, and the relative movement of the inner rail 13 is automatically performed by the first and second coil springs 29 and 31. Lock makes it possible to equip the following relative movement.

前記直線ダンパ２５は、一端が第１の連結板２１ａ，２１ｂに回動可能に結合され他端がハウジング１９に回動可能に結合され、前記回転ダンパ２７は、ハウジング１９に直線移動可能に支持され一端が前記第２の連結板２３ａ，２３ｂに回動可能に結合されたラック部材７５のラック７７に噛み合うピニオン７３に連動結合されたため、インナー・レール１３の相対移動開始により直線ダンパ２５及び回転ダンパ２７の双方を作用させ、移動途中で直線ダンパ２５の作用を停止させ、回転ダンパ２７のみの作用とすることができる。
［その他］
回転ダンパ２７は、直線ダンパ２５よりもダンピング力を弱めた直線ダンパに換えることもできる。 One end of the linear damper 25 is rotatably connected to the first connecting plates 21 a and 21 b and the other end is rotatably connected to the housing 19. The rotary damper 27 is supported by the housing 19 so as to be linearly movable. Since one end thereof is interlocked and coupled to the pinion 73 that meshes with the rack 77 of the rack member 75 that is rotatably coupled to the second connecting plates 23a and 23b, the linear damper 25 and the rotation are started by the relative movement of the inner rail 13 being started. Both of the dampers 27 are actuated, and the action of the linear damper 25 is stopped in the middle of movement, so that only the rotary damper 27 can be acted on.
[Others]
The rotary damper 27 can be replaced with a linear damper having a damping force weaker than that of the linear damper 25.
