Abstract

A slider unit equipped with a damper comprises: a slider body provided to either a fixed body or a movement body which moves relative to the fixed body, separably engaged with the other body, and sliding as the other body moves; and a damper which, as the slider body moves in a predetermined direction, acts against the movement of the slider body to damp the kinetic energy of the slider body. The slider body is provided with a fixed section, a movable section slidably mounted to the fixed section and separably engaged with the other body, and an elastic member consisting of a spring material and mounted between the fixed section and the movable section. The elastic member is mounted between the fixed section and the movable section so as to press the movable section in the direction of movement thereof. The elastic member is elastically deformed when the movable section moves to cause the portion at which the elastic member and the movable section are mounted to each other to approach the portion at which the elastic member and the fixed section are mounted to each other. Also, the elasticity of the elastic member is restored when the portion at which the elastic member and the movable section are mounted to each other passes through the reversing point of the elastic member.

This application claims priority based on Japanese Patent Application No. 2009-127662 filed in Japan on May 27, 2009, the contents of which are incorporated herein by reference.
 家具等の収納具では、その抽斗等の移動体の閉動作に伴って衝撃を生じる。その結果、騒音を生じたり、繰り返しの閉動作に伴う衝撃により移動体および収納具本体が損傷するといった問題がある。そこで、従来では、このような閉動作による衝撃を緩和するため、抽斗等の移動体とこれを移動可能に保持する収納具本体(固定体)との間に閉ダンパー装置を備えた、閉動作および/または引き込みのための装置が提案されている(特許文献1参照)。 In storage equipment such as furniture, an impact is generated when the moving body such as the drawer is closed. As a result, there is a problem in that noise is generated or the moving body and the storage tool main body are damaged due to impacts caused by repeated closing operations. Therefore, conventionally, in order to alleviate the impact caused by such a closing operation, the closing operation is provided with a closed damper device between a moving body such as a drawer and a housing body (fixed body) that holds the moving body movably. And / or a device for retraction has been proposed (see Patent Document 1).

 ところで、前記家具等の収納具では、地震等における振動などや、閉動作に伴う衝撃の反作用によって抽斗等が自動的に開くのを防止するため、ロック機構が設けられている。このロック機構は、ある程度の引張力で引き出さない(引っ張らない)と、抽斗等が開かないようにするためのものである。また、このようなロック機構では、抽斗等を開いた(引き出した)後、再度閉じる(引き込む)際に抽斗等と前記装置との接続が容易になるように、前記装置を所定の状態に保持する必要がある。そして、前記の特許文献1に開示された装置においても、引っ張りバネ、カム、ハウジングにおけるガイドウェイなどからなるロック機構が開示されている。 By the way, in the storage device such as furniture, a lock mechanism is provided in order to prevent the drawer or the like from automatically opening due to vibration in an earthquake or the like, or reaction of impact caused by the closing operation. This lock mechanism is for preventing the drawer or the like from opening unless it is pulled out (not pulled) with a certain amount of tensile force. Further, in such a lock mechanism, the device is held in a predetermined state so that the device can be easily connected to the device when the drawer is opened (drawn) and then closed again (drawn). There is a need to. The device disclosed in Patent Document 1 also discloses a lock mechanism including a tension spring, a cam, a guide way in a housing, and the like.
 しかしながら、この特許文献1の装置では、抽斗等が自動的に開くのを防止するための機能と、この装置を所定の状態に保持するための機能と、を併せ持つ必要がある。その為、前述したように引っ張りバネ、カム、ハウジングにおけるガイドウェイなどからなるロック機構が必要とされている。したがって、この特許文献1の装置では、装置自体を構成する部品の数が多くなるため、装置自体に要するスペースが大きくなり、さらに装置を容易に組み立てることができない。 However, the device of Patent Document 1 needs to have both a function for preventing the drawer and the like from automatically opening and a function for holding the device in a predetermined state. For this reason, as described above, a lock mechanism including a tension spring, a cam, a guide way in the housing, and the like is required. Therefore, in the apparatus of Patent Document 1, since the number of components constituting the apparatus itself is increased, a space required for the apparatus itself is increased, and further, the apparatus cannot be easily assembled.
 本発明は前記事情に鑑みてなされたもので、家具等の固定体とこれに対して移動する抽斗等の移動体との間に設けられるスライドユニットとして、ダンパーによって閉動作の際の衝撃を緩和するとともに、移動体をロックするロック機構を備え、しかも部品点数を少なくしてスペース効率を高め、組み立て性も良好にした、ダンパー付きスライドユニットを提供することを目的とする。 The present invention has been made in view of the above circumstances, and as a slide unit provided between a stationary body such as furniture and a movable body such as a drawer that moves relative to the stationary body, the damper reduces the impact during the closing operation. In addition, an object of the present invention is to provide a slide unit with a damper that includes a lock mechanism that locks a moving body, and that has a reduced number of parts to improve space efficiency and good assembly.
 本発明のダンパー付きスライドユニットは、固定体とこの固定体に対して移動する移動体との一方に設けられ、前記固定体と前記移動体との他方に着脱可能に係合し、この他方の相対移動に伴ってスライド移動するスライダー本体と、このスライダー本体の所定方向への移動に抗してその移動エネルギーを減衰させるダンパーと、を備える。さらに、前記スライダー本体は、固定部と、この固定部に対してスライド可能に取り付けられ、かつ前記他方に着脱可能に係合する可動部と、前記固定部と前記可動部との間に取り付けられたバネ材からなる弾性部材と、を備える。さらに、前記弾性部材は、前記可動部をその移動方向に付勢するように、前記固定部と可動部との間に取り付けられている。この弾性部材は、前記可動部が移動して、前記弾性部材と前記可動部との取付部が、前記弾性部材と前記固定部との取付部に近づくことで、弾性変形する。また、この弾性部材は、前記弾性部材と前記可動部との取付部が、この弾性部材の反転ポイントを通過することで、弾性復帰する。 The slide unit with a damper according to the present invention is provided on one of a fixed body and a moving body that moves relative to the fixed body, and is detachably engaged with the other of the fixed body and the moving body. A slider body that slides with relative movement; and a damper that attenuates the movement energy against the movement of the slider body in a predetermined direction. Further, the slider body is attached between the fixed portion, the movable portion that is slidably attached to the fixed portion and that is detachably engaged with the other, and the fixed portion and the movable portion. And an elastic member made of a spring material. Further, the elastic member is attached between the fixed portion and the movable portion so as to urge the movable portion in the moving direction. The elastic member is elastically deformed when the movable portion moves and the attachment portion between the elastic member and the movable portion approaches the attachment portion between the elastic member and the fixed portion. In addition, the elastic member returns elastically when the attachment portion between the elastic member and the movable portion passes through the reversal point of the elastic member.
 このダンパー付きスライドユニットは、スライダー本体と、該スライダー本体の所定方向への移動に抗してその移動エネルギーを減衰させるダンパーと、を備えている。そのため、固定体に対する移動体の移動、すなわち家具等の固定体に対する抽斗等の移動体の閉動作の際の衝撃を、スライダー本体を介してダンパーで緩和・吸収することができる。また、固定部と可動部との間に取り付けられる弾性部材が、これら固定部と可動部との相対移動によって弾性変形するとともに、反転することで弾性復帰し、可動部をその移動方向に付勢するように取り付けられている。そのため、前記固定部と可動部との相対位置に基づき、抽斗等の移動体が開くのを防止するロック機能と、前記移動体が開いている際にスライダー本体を所定の状態に保持するロック機能とを共に実現する。また、このように弾性部材が弾性変形するとともに反転して弾性復帰し、可動部に対する付勢方向を反転させるため、従来のスライド装置において前進と後退とを切り替えるのに必要だったクラッチの機能を、この弾性部材が発揮する。 The slide unit with a damper includes a slider body and a damper that attenuates the movement energy against the movement of the slider body in a predetermined direction. Therefore, the impact of the movement of the moving body relative to the fixed body, that is, the closing operation of the moving body such as the drawer to the fixed body such as furniture can be relaxed and absorbed by the damper via the slider body. In addition, the elastic member attached between the fixed portion and the movable portion is elastically deformed by the relative movement between the fixed portion and the movable portion, and is elastically restored by reversing to bias the movable portion in the moving direction. It is attached to do. Therefore, based on the relative position between the fixed portion and the movable portion, a lock function that prevents the moving body such as a drawer from opening, and a lock function that holds the slider body in a predetermined state when the moving body is open. And realize together. In addition, since the elastic member is elastically deformed and reversed and elastically returns, and the urging direction with respect to the movable portion is reversed, the function of the clutch necessary for switching between the forward movement and the backward movement in the conventional slide device is provided. This elastic member exhibits.
 また、前記ダンパー付きスライドユニットにおいて、前記可動部は、その先端側に開閉可能に形成された一対の挟持片を備え、この一対の挟持片が開閉することにより、前記固定体と移動体との他方に着脱可能に係合するのが好ましい。
 このようにすれば、前記他方に係合する構成要素を、スライダー本体の可動部に一体に形成することが可能になる。したがって、スライドユニット全体に必要な部品点数が少なくなる為、ダンパー付きスライドユニット自体に要するスペースが小さくて済み、さらにスライドユニットを容易に組み立てやすくすることができる。
Further, in the slide unit with a damper, the movable portion includes a pair of sandwiching pieces formed to be openable and closable at a distal end side thereof, and the pair of sandwiching pieces opens and closes to thereby form the fixed body and the moving body. The other is preferably detachably engaged.
If it does in this way, it will become possible to form in a movable part of a slider main body the component engaged with said other one. Therefore, since the number of parts required for the entire slide unit is reduced, the space required for the slide unit with a damper is small, and the slide unit can be easily assembled.
 また、前記ダンパー付きスライドユニットにおいて、前記ダンパーは、有底筒状のシリンダーと、このシリンダー内にその軸方向に沿って移動可能に収容されたヘッドと、前記シリンダーの開口側を閉塞する蓋部と、この蓋部に設けられた貫通孔を通って前記ヘッドに連結するとともに、前記シリンダーの軸方向に沿って前記蓋部に対して液密に摺動するリードと、前記シリンダー内において該シリンダーの底部と前記ヘッドとの間に配設されて該ヘッドを前記底部と反対の側に付勢する付勢部材と、前記シリンダー内に充填された粘性流体と、を有するのが好ましい。また、前記ヘッドには、前記シリンダーの底部側と蓋部側との間で前記粘性流体を流動可能にする開口が形成され、弾性変形することでこのヘッドの前記開口の一部を覆うよう構成されたエラストマー又は軟質ゴムからなるバルブが設けられているのが好ましい。さらに、前記リードが、前記スライダー本体の後端部に当接可能に配置され、あるいは連結しているのが好ましい。 Further, in the slide unit with a damper, the damper includes a bottomed cylindrical cylinder, a head accommodated in the cylinder so as to be movable along the axial direction, and a lid portion that closes the opening side of the cylinder. And a lead that is coupled to the head through a through-hole provided in the lid, and that slides liquid-tightly with respect to the lid along the axial direction of the cylinder, and the cylinder in the cylinder It is preferable that a biasing member disposed between the bottom of the cylinder and the head to bias the head to a side opposite to the bottom and a viscous fluid filled in the cylinder. The head is formed with an opening that allows the viscous fluid to flow between a bottom side and a lid side of the cylinder, and is configured to cover a part of the opening of the head by elastic deformation. Preferably, a valve made of an elastomer or soft rubber is provided. Furthermore, it is preferable that the lead is disposed or connected so as to be able to contact the rear end of the slider body.
 このようにすれば、特にスライダー本体がダンパー側に急激に移動し、リードがシリンダーの底部側に移動した場合に、前記バルブが弾性変形してヘッドの前記開口の一部を覆う。これより、シリンダー底部側の粘性流体が前記開口を通ってシリンダー蓋部側に相対的に移動するのを妨げる。これによりシリンダー底部側へのヘッドの移動が抑制され、このヘッドに連結するリードの前記底部側への移動も抑制される。したがって、このダンパーは、抽斗等の前記移動体の閉動作の際の衝撃を、より良好に緩和・吸収することが可能になる。 In this way, especially when the slider main body suddenly moves to the damper side and the lead moves to the bottom side of the cylinder, the valve is elastically deformed to cover a part of the opening of the head. Thus, the viscous fluid on the cylinder bottom side is prevented from moving relatively to the cylinder lid side through the opening. Thereby, the movement of the head to the cylinder bottom side is suppressed, and the movement of the lead connected to the head to the bottom side is also suppressed. Therefore, this damper can more effectively mitigate and absorb the impact when the moving body such as the drawer is closed.
 また、前記ダンパー付きスライドユニットにおいては、前記リードが、前記スライダー本体の後端部に連結しているのが好ましい。
 このようにすれば、スライダー本体の移動に伴って、ダンパーが、より円滑にその効果を発揮するようになる。
In the slide unit with a damper, it is preferable that the lead is connected to a rear end portion of the slider body.
In this way, the damper exhibits its effect more smoothly as the slider body moves.
 また、前記反転ポイントが、前記弾性部材と前記可動部との前記取付部と、前記弾性部材と前記固定部との前記取付部と、が並んだ、前記可動部の移動方向と直行する直線であることが好ましい。 Further, the reversal point is a straight line that is orthogonal to the moving direction of the movable part, in which the attachment part of the elastic member and the movable part and the attachment part of the elastic member and the fixed part are arranged. Preferably there is.
 本発明のダンパー付きスライドユニットにあっては、反転バネとして機能する弾性部材が、抽斗等の移動体が開くのを防止するロック機能と、前記移動体が開いている際にスライダー本体を所定の状態に保持するロック機能と、前進と後退とを切り替えるためのクラッチの機能と、を併せ持つ。その結果、スライドユニット全体に必要な部品点数が少なくなる為、ダンパー付きスライドユニット自体に要するスペースが小さくて済み、さらにスライドユニットを容易に組み立てやすくすることができる。 In the slide unit with a damper of the present invention, the elastic member that functions as a reversing spring has a lock function that prevents the moving body such as a drawer from opening, and the slider main body is moved to a predetermined position when the moving body is open. It has both a lock function for maintaining the state and a clutch function for switching between forward and reverse. As a result, since the number of parts required for the entire slide unit is reduced, the space required for the slide unit with damper itself can be reduced, and the slide unit can be easily assembled.

A bottom guide groove 11 is formed on the surface (upper surface) of the bottom plate 7, and attachment holes 12 are formed on both sides of the bottom guide groove 11 and further on the end side of the side plates 9 and 9. The lower guide groove 11 is for guiding the slider 5 as described later. The attachment hole 12 is a hole for inserting a screw or the like for attaching the base 4 to the fixed body.
 ダンパー保持筒8内に、図1A~図3Bに示したように、外形状が円柱状のダンパー3が挿入され保持固定される。
 側板9、9は、底板7の表面側に延出して形成されたもので、これらの間にスライダー5が配置されている。これら側板9、9の上端部には、カバー13が取り付けられており、これによってスライダー5はカバー13に覆われている。カバー13には、その一方の側(前記ダンパー保持筒8と反対の側)に開口する切欠14が形成されており、その裏面に前記スライダー5を案内するための上ガイド溝15が形成されている。
 取付板10は、底板7と同じ平面を成すように形成されたもので、その表裏面を貫通する取付孔10aが形成されたものである。取付孔10aには、取付ピン20が挿入固定されるとともに前記反転バネ6の一端が保持固定されている。
As shown in FIGS. 1A to 3B, the damper 3 having a cylindrical outer shape is inserted and held and fixed in the damper holding cylinder 8.
The side plates 9, 9 are formed to extend to the surface side of the bottom plate 7, and the slider 5 is disposed between them. A cover 13 is attached to the upper ends of these side plates 9, and the slider 5 is covered with the cover 13 by this. The cover 13 is formed with a notch 14 opened on one side thereof (the side opposite to the damper holding cylinder 8), and an upper guide groove 15 for guiding the slider 5 is formed on the back surface thereof. Yes.
The mounting plate 10 is formed so as to form the same plane as the bottom plate 7, and is formed with mounting holes 10 a penetrating the front and back surfaces thereof. An attachment pin 20 is inserted and fixed in the attachment hole 10a, and one end of the reversing spring 6 is held and fixed.
 スライダー5は、ポリアセタール(POM)等の樹脂によって形成され、底板7の長辺方向に沿って進退可能(移動可能)に配置されている。このスライダー5は、図4に示すように、その先端側(前記ダンパー保持筒8と反対の側)が一対の挟持片16、16からなり、後端側(前記ダンパー保持筒8の側)に前記ダンパー3と連結する連結部(後端部)17が形成されている。また、これら挟持片16、16と連結部17との間が、可動本体部18となっている。可動本体部18と一対の挟持片16、16とは、薄厚の連結板18aによって連結されている。そして、図4に示したように、その先端側の一対の挟持片16、16が開いた状態で、スライダー5は一体成形されている。 The slider 5 is made of a resin such as polyacetal (POM) and is disposed so as to be movable back and forth (movable) along the long side direction of the bottom plate 7. As shown in FIG. 4, the slider 5 has a pair of clamping pieces 16 and 16 on the front end side (the side opposite to the damper holding cylinder 8), and on the rear end side (the damper holding cylinder 8 side). A connecting portion (rear end portion) 17 that is connected to the damper 3 is formed. Further, a movable main body 18 is formed between the sandwiching pieces 16 and 16 and the connecting portion 17. The movable main body 18 and the pair of sandwiching pieces 16, 16 are connected by a thin connecting plate 18a. As shown in FIG. 4, the slider 5 is integrally formed with the pair of sandwiching pieces 16, 16 on the front end side being opened.

 可動本体部18は、その幅が側板9、9の間隔にほぼ一致するように形成され、一対の取付孔19、19が設けられている。これら取付孔19、19には、前記取付孔10aと同様に、取付ピン20が挿入固定されるとともに前記反転バネ6の他端が保持固定されている。
 連結部17は、その後端に連結片17aを介して連結ボス17bを形成したもので、この連結ボス17bが後述するダンパー3のリード31に連結する。また、この連結部17は、前記可動本体部18より幅が狭く形成されている。
The movable main body 18 is formed so that the width thereof substantially coincides with the interval between the side plates 9 and 9, and a pair of attachment holes 19 and 19 are provided. Similar to the mounting hole 10a, the mounting pins 20 are inserted and fixed in the mounting holes 19 and 19, and the other end of the reversing spring 6 is held and fixed.
The connecting portion 17 has a connecting boss 17b formed at its rear end via a connecting piece 17a, and this connecting boss 17b is connected to a lead 31 of the damper 3 described later. The connecting portion 17 is formed to be narrower than the movable main body portion 18.
 これら可動本体部18と連結部17との上面には、その前後方向(進退方向)に沿って上突条21が形成されており、この上突条21に前記カバー13の上ガイド溝15が摺動可能に係合している。また、連結部17の下面には、下突条(図示せず)が形成されており、この下突条に前記底板7の下ガイド溝11が摺動可能に係合している。これによって、スライダー5は、その下面側及び上面側が所定方向(底板7の長辺方向)に案内される。さらに、この所定方向での進退を安定させるため、スライダー5は、側板9、9間に挟持されて底板7の短辺方向への移動を規制されている。 Upper ridges 21 are formed on the upper surfaces of the movable main body 18 and the connecting portion 17 along the front-rear direction (back and forth direction), and the upper guide grooves 15 of the cover 13 are formed on the upper ridges 21. It is slidably engaged. Further, a lower protrusion (not shown) is formed on the lower surface of the connecting portion 17, and the lower guide groove 11 of the bottom plate 7 is slidably engaged with the lower protrusion. Thereby, the lower surface side and the upper surface side of the slider 5 are guided in a predetermined direction (long side direction of the bottom plate 7). Further, in order to stabilize the advance and retreat in the predetermined direction, the slider 5 is sandwiched between the side plates 9 and 9 to restrict the movement of the bottom plate 7 in the short side direction.
 反転バネ6は、ステンレスや高張力鋼などの金属からなるもので、本実施形態では金属製の一本の線材(バネ材)から成形されたものが用いられている。具体的には、図4に示すように、この反転バネ6は、一本の線材をその中心部で数回周回させ、この周回部6aの両側を、この周回部6aを中心として所定角度に折り曲げたものである。また、折り曲げた両端部は、さらに一周に近く周回させ、取付部6b、6bとしている。 The reversal spring 6 is made of a metal such as stainless steel or high-tensile steel, and in this embodiment, one formed from a single metal wire (spring material) is used. Specifically, as shown in FIG. 4, the reversing spring 6 allows a single wire to circulate several times at its central portion, so that both sides of the circular portion 6a are at a predetermined angle around the circular portion 6a. It is a bent one. Moreover, the bent both ends are further made to circulate near one round, and it is set as the attachment parts 6b and 6b.
 このような反転バネ6は、図1A~図3Bに示したように、その取付部6b、6bのうちの一方が取付板10の取付孔10aに取付ピン20を介して取り付け固定され、他方がスライダー5の可動本体部18の取付孔19に取付ピン20を介して取り付け固定されている。なお、取付部6bの内径は、取付ピン20の外径より大きく形成されている。これによって、各取付部6bは、取付ピン20に対して回動可能になっている。 As shown in FIGS. 1A to 3B, such a reversing spring 6 has one of its attachment portions 6b, 6b attached and fixed to the attachment hole 10a of the attachment plate 10 via an attachment pin 20, and the other of the attachment portions 6b and 6b. An attachment pin 20 is attached and fixed to the attachment hole 19 of the movable main body 18 of the slider 5. The inner diameter of the mounting portion 6b is formed larger than the outer diameter of the mounting pin 20. As a result, each attachment portion 6 b is rotatable with respect to the attachment pin 20.
 また、可動本体部18に取り付けられる取付部6bは、図4に示したように、可動本体部18の裏面側に、取付ピン20を介して取り付けられている。可動本体部18及び連結部17の裏面側には凹部22が形成されており、反転バネ6や取付ピン20は、この凹部22内に配置されている。このように、スライダー5は底板7の表面上を摺動する際、反転バネ6や取付ピン20に干渉されないように設計されている。 Further, as shown in FIG. 4, the attachment portion 6 b attached to the movable main body portion 18 is attached to the back surface side of the movable main body portion 18 via an attachment pin 20. A concave portion 22 is formed on the back side of the movable main body 18 and the connecting portion 17, and the reversing spring 6 and the mounting pin 20 are disposed in the concave portion 22. Thus, the slider 5 is designed so as not to interfere with the reversing spring 6 and the mounting pin 20 when sliding on the surface of the bottom plate 7.
 ここで、スライダー(可動部)5をベース(固定部)4の底板7に対して、図3A、3Bから図2A、2Bを経て図1A、1Bに示す状態に移動させると、あるいはその逆に図1A、2Bから図2A、2Bを経て図3A,3Bに示す状態に移動させると、スライダー5の移動に伴って取付板10の取付孔10aと可動本体部18の取付孔19との距離が変位する。そのため、反転バネ6は、その変位量に応じて伸縮する。すなわち、反転バネ6の両端部が最も近づいて取付孔10aと取付孔19との位置がスライド部9の移動方向(進退方向)で一致したとき、反転バネ6は最大に弾性変形する。そして、その弾性復帰による付勢力は、取付孔10aの取付ピン20及び取付孔19の取付ピン20に対して、スライダー5の移動方向と直交する方向にのみかかり、移動方向への付勢力はゼロになる。そのため、取付孔10aと取付孔19との位置がスライド部9の移動方向(進退方向)と直交する直線上に並んだ位置が、反転バネ6の反転ポイントとなる。 Here, when the slider (movable part) 5 is moved from the bottom plate 7 of the base (fixed part) 4 to the state shown in FIGS. 1A and 1B through FIGS. 2A and 2B, or vice versa. When the slider 5 is moved from the state shown in FIGS. 1A and 2B to the state shown in FIGS. 3A and 3B, the distance between the mounting hole 10a of the mounting plate 10 and the mounting hole 19 of the movable main body 18 is increased. Displace. Therefore, the reversing spring 6 expands and contracts according to the amount of displacement. That is, when both end portions of the reversing spring 6 come closest to each other and the positions of the mounting hole 10a and the mounting hole 19 coincide with each other in the moving direction (advancing / retreating direction) of the slide portion 9, the reversing spring 6 is elastically deformed to the maximum. The biasing force due to the elastic return is applied only to the mounting pin 20 of the mounting hole 10a and the mounting pin 20 of the mounting hole 19 in the direction orthogonal to the moving direction of the slider 5, and the biasing force in the moving direction is zero. become. Therefore, a position where the positions of the mounting hole 10 a and the mounting hole 19 are aligned on a straight line orthogonal to the moving direction (advancing and retracting direction) of the slide portion 9 is the reversal point of the reversing spring 6.
 そして、この反転ポイントを過ぎ、例えば図1Aおよび図1Bに示したようにスライダー5が前進すると、スライダー5の上突条21及び下突条(図示せず)が、それぞれに係合する上ガイド溝15、下ガイド溝11の先端において係止される。これにより、スライダー5は前進を停止する。また、図3Aおよび図3Bに示したように、スライダー5が後退すると、スライダー5の上突条21及び下突条(図示せず)が、それぞれに係合する上ガイド溝15、下ガイド溝11の後端において係止される。これによって、スライダー5は後退を停止する。したがって、スライダー5は、その移動範囲が上突条21と上ガイド溝15、下突条と下ガイド溝11によって制限されている。 When the reversal point is passed and the slider 5 moves forward as shown in FIGS. 1A and 1B, for example, the upper guide 21 and the lower guide (not shown) of the slider 5 engage with each other. The groove 15 is locked at the tip of the lower guide groove 11. As a result, the slider 5 stops moving forward. Further, as shown in FIGS. 3A and 3B, when the slider 5 moves backward, the upper protrusion 21 and the lower protrusion (not shown) of the slider 5 engage with the upper guide groove 15 and the lower guide groove, respectively. 11 is locked at the rear end. As a result, the slider 5 stops moving backward. Accordingly, the movement range of the slider 5 is limited by the upper protrusion 21 and the upper guide groove 15, and the lower protrusion and the lower guide groove 11.
 また、図1Aおよび図1Bに示したように、スライダー5の前進が停止した状態では、スライダー5側の取付孔19が取付板10の取付孔10aより前進方向側に位置するので、前記反転バネ6は、ベース(固定部)4に対してスライダー(可動部)5をその前進方向に付勢する。これにより、反転バネ5は、スライダー5の前進が停止した状態でロックする。同様に、図3Aおよび図3Bに示したように、スライダー5の後退が停止した状態では、前記反転バネ6がスライダー(可動部)5をその後退方向に付勢することにより、スライダー5の後退が停止した状態でロックする。したがって、反転バネ5は、後述するように、抽斗等の移動体が開くのを防止するロック機能と、移動体が開いている際にスライダー5(スライダー本体2)を所定の状態に保持するロック機能とを、共に有する。
 また、この反転バネ6は、弾性変形するとともに反転して弾性復帰し、スライダー5に対する付勢方向を反転させる。そのため、従来のスライド装置においてスライダーの前進と後退とを切り替えるのに必要だったクラッチの機能を、この反転バネ6が発揮する。
Further, as shown in FIGS. 1A and 1B, in the state where the advance of the slider 5 is stopped, the attachment hole 19 on the slider 5 side is located on the advance direction side with respect to the attachment hole 10a of the attachment plate 10. 6 urges the slider (movable part) 5 in the forward direction with respect to the base (fixed part) 4. As a result, the reversing spring 5 is locked in a state where the forward movement of the slider 5 is stopped. Similarly, as shown in FIGS. 3A and 3B, in a state in which the slider 5 is not retracted, the reversing spring 6 biases the slider (movable part) 5 in the retracting direction, so that the slider 5 retracts. Locks when is stopped. Therefore, as will be described later, the reversing spring 5 has a lock function that prevents the moving body such as a drawer from opening, and a lock that holds the slider 5 (slider body 2) in a predetermined state when the moving body is open. It has both functions.
Further, the reversing spring 6 is elastically deformed and reversed to be elastically restored to reverse the biasing direction with respect to the slider 5. For this reason, the reversing spring 6 exhibits the clutch function necessary for switching between forward and backward movement of the slider in the conventional slide device.
 ダンパー3は、図4に示したように、外形状が円柱状のシリンダー30と、このシリンダー30内に移動可能に内挿され、かつその一端側が引き出されてなるリード31とを備える。このリード31は、前記スライダー5の連結部17(連結片17a)に連結するものである。そして、このダンパー3は、スライダー5(スライダー本体2)の後退移動(所定方向への移動)に抗して、その移動エネルギーを減衰させる。 As shown in FIG. 4, the damper 3 includes a cylinder 30 whose outer shape is a columnar shape, and a lead 31 that is movably inserted into the cylinder 30 and that has one end pulled out. The lead 31 is connected to the connecting portion 17 (connecting piece 17a) of the slider 5. The damper 3 attenuates the movement energy against the backward movement (movement in a predetermined direction) of the slider 5 (slider body 2).
 すなわち、このダンパー3は、図5に示すように、有底筒状のシリンダー30と、このシリンダー30内にその軸方向に沿って移動可能に収容されたヘッド32と、シリンダー30の開口側を閉塞する蓋部33と、該蓋部33に設けられた貫通孔33aを通ってヘッド32に連結するリード31と、ヘッド32とリード31との間に配設されたバルブ34と、を備える。さらに、このダンパー3は、シリンダー30内に、コイルスプリング(付勢部材)35と粘性流体36とを有している。 That is, as shown in FIG. 5, the damper 3 includes a bottomed cylindrical cylinder 30, a head 32 accommodated in the cylinder 30 so as to be movable along the axial direction, and an opening side of the cylinder 30. A lid portion 33 to be closed, a lead 31 connected to the head 32 through a through-hole 33 a provided in the lid portion 33, and a valve 34 disposed between the head 32 and the lead 31 are provided. Further, the damper 3 has a coil spring (biasing member) 35 and a viscous fluid 36 in the cylinder 30.
 シリンダー30は、前記ダンパー保持筒8内に挿入され保持固定される樹脂製部材である。
 ヘッド32は、図5、図6に示すように、略円盤状の円盤部32aと、この円盤部32aの中心部に設けられた軸部32bと、からなる樹脂製のものである。円盤部32aの外径は、前記シリンダー30の内径とほぼ等しく形成されている(詳しくは、円盤部32aの外径は、シリンダー30の内径より僅かに小さく形成されている)。したがって、ヘッド32は、シリンダー30に対してその軸線方向に摺動するように設計されている。
The cylinder 30 is a resin member that is inserted into the damper holding cylinder 8 and is held and fixed.
As shown in FIGS. 5 and 6, the head 32 is made of a resin including a substantially disk-shaped disk part 32 a and a shaft part 32 b provided at the center of the disk part 32 a. The outer diameter of the disk portion 32a is formed to be substantially equal to the inner diameter of the cylinder 30 (specifically, the outer diameter of the disk portion 32a is formed slightly smaller than the inner diameter of the cylinder 30). Therefore, the head 32 is designed to slide in the axial direction with respect to the cylinder 30.
 ただし、この円盤部32aには、図6に示すように、その外周部に四つの開口32cが形成されている。これら開口32cは、円盤部32aの周方向において等間隔で4箇所形成されたもので、円盤部32aの外周縁から中心側に切り欠かれてなる半円形状の切欠によって形成されている。このように、ヘッド32は、シリンダー30内に充填された粘性流体36を、開口32cによってシリンダー30の底部30a側と蓋部33側との間で流動可能にしている。また、軸部32bには、径の異なる部位が複数(本実施形態では3つ)形成されている。 However, as shown in FIG. 6, four openings 32c are formed in the outer periphery of the disk portion 32a. These openings 32c are formed at four positions at equal intervals in the circumferential direction of the disk portion 32a, and are formed by semicircular cutouts cut out from the outer peripheral edge of the disk portion 32a toward the center. Thus, the head 32 enables the viscous fluid 36 filled in the cylinder 30 to flow between the bottom 30a side and the lid 33 side of the cylinder 30 through the opening 32c. In addition, a plurality (three in the present embodiment) of parts having different diameters are formed on the shaft portion 32b.
 図5に示すようにリード31には、シリンダー30内に位置する後端(他端)に嵌合穴31aが形成されており、この嵌合穴31aが、前記ヘッド32の軸部32bの先端側に位置する最小径の部位321に嵌合している。これによって、リード31は、このヘッド32と一体に固定されている。また、リード31には、その先端(一端)部に連結孔31bが形成されており、この連結孔31bは、前記スライダー5の連結部17の連結ボス17bに係合している。これにより、リード31は、スライダー5(スライダー本体2)の後端部に連結している。 As shown in FIG. 5, the lead 31 is formed with a fitting hole 31 a at the rear end (the other end) located in the cylinder 30, and this fitting hole 31 a is the tip of the shaft portion 32 b of the head 32. It is fitted to a portion 321 having the smallest diameter located on the side. As a result, the lead 31 is fixed integrally with the head 32. The lead 31 has a connecting hole 31 b formed at the tip (one end) thereof, and the connecting hole 31 b is engaged with the connecting boss 17 b of the connecting portion 17 of the slider 5. Thereby, the lead 31 is connected to the rear end portion of the slider 5 (slider body 2).
 蓋部33は、シリンダー30の開口内に嵌合する円筒部33bと、シリンダー30の一方の端面を形成する円盤状の蓋板33cと、からなる樹脂製のもので、シリンダー30に超音波溶着や接着によって取り付けられている。円筒部33b、蓋板33cには、前述したようにこれらを貫通する貫通孔33aが形成されており、この貫通孔33aに前記リード31が摺動可能に内挿されている。円筒部33b内には、Oリング37が二つ配設されている。これらOリング37がリード31に外挿されていることにより、リード31はOリング37に対して、すなわち蓋部33の貫通孔33aに対して、液密に摺動する。 The lid portion 33 is made of resin and includes a cylindrical portion 33 b that fits into the opening of the cylinder 30 and a disk-like lid plate 33 c that forms one end surface of the cylinder 30. And are attached by gluing. As described above, the cylindrical portion 33b and the cover plate 33c are formed with the through holes 33a penetrating them, and the leads 31 are slidably inserted into the through holes 33a. Two O-rings 37 are disposed in the cylindrical portion 33b. Since these O-rings 37 are extrapolated to the leads 31, the leads 31 slide in a liquid-tight manner with respect to the O-rings 37, that is, with respect to the through holes 33 a of the lid portion 33.
 バルブ34は、エラストマー又は軟質ゴムからなる部材であって、図7Aおよび図7Bに示すように、平面視(正面視)で円形状で、その外周部(へり部)34aを一方の側に湾曲させた皿状部材であり、中心部に貫通孔34bを有する。このバルブ34は、その嵌合孔34aがヘッド32の軸部32bの中央に位置する二番目の径の部位322、及び後端側に位置する最大径の部位323に嵌合したことにより、このヘッド32と前記リード31との間に挟持され固定されている。また、このバルブ34では、前記外周部34aが薄肉に形成されている。これによって、この外周部34aは、前記ヘッド32の円盤部32aに弾性変形可能に当接し、あるいは僅かに隙間をあけて配置されている。 The valve 34 is a member made of elastomer or soft rubber, and as shown in FIGS. 7A and 7B, has a circular shape in plan view (front view), and its outer peripheral portion (edge portion) 34a is curved to one side. The dish-shaped member has a through hole 34b in the center. This valve 34 has a fitting hole 34a fitted into the second diameter portion 322 located in the center of the shaft portion 32b of the head 32 and the largest diameter portion 323 located on the rear end side. It is clamped and fixed between the head 32 and the lead 31. Moreover, in this valve | bulb 34, the said outer peripheral part 34a is formed thinly. As a result, the outer peripheral portion 34a abuts on the disk portion 32a of the head 32 so as to be elastically deformable, or is disposed with a slight gap.
 また、この薄肉の外周部34aは、弾性変形していない状態では、その外径(バルブ34の外径)が前記ヘッド32の円盤部32aの外径より小さい。したがって、この円盤部32aに形成された前記開口32cを十分に塞ぐことなく(開口32cの大半部を覆うことなく)、その一部を開口させたままの状態にしている。そして、後述するようにバルブ34の外周部34aが弾性変形すると、外周部34aが前記開口32cのほぼ全域を塞ぐようになっている。すなわち、開口32cは円盤部32aの外周縁からその中心側に切り欠かれてなる切欠によって形成されているので、バルブ34が弾性変形してその外周部34aを拡げることにより、この開口32cをより広く覆うようになっている。さらに、このように弾性変形することにより、外周部34aは、その外周縁をシリンダー30の内面に一部接触させるようになっている。 In addition, the outer peripheral portion 34a of this thin wall has an outer diameter (the outer diameter of the valve 34) smaller than the outer diameter of the disk portion 32a of the head 32 when not elastically deformed. Accordingly, the opening 32c formed in the disk portion 32a is not sufficiently blocked (not covering most of the opening 32c), and a part of the opening 32c is left open. As will be described later, when the outer peripheral portion 34a of the valve 34 is elastically deformed, the outer peripheral portion 34a covers almost the entire area of the opening 32c. That is, since the opening 32c is formed by a notch that is cut out from the outer peripheral edge of the disk portion 32a toward the center thereof, the valve 34 is elastically deformed to widen the outer peripheral portion 34a, thereby further opening the opening 32c. Covers widely. Further, by elastically deforming in this way, the outer peripheral portion 34 a is brought into partial contact with the inner surface of the cylinder 30.
 図5に示したように、コイルスプリング35は、前記シリンダー30内において、このシリンダー30の底部30aと前記ヘッド32との間に配設されたもので、このヘッド32を前記底部と反対の側に付勢するものである。このようにヘッド32を付勢することにより、コイルスプリング35はヘッド32の後退移動(シリンダー30の底部30a側への移動)に対して抵抗力を付与し、緩衝効果を発揮する。 As shown in FIG. 5, the coil spring 35 is disposed in the cylinder 30 between the bottom 30a of the cylinder 30 and the head 32, and the head 32 is disposed on the side opposite to the bottom. It will be energized. By urging the head 32 in this way, the coil spring 35 provides resistance against the backward movement of the head 32 (movement toward the bottom 30a of the cylinder 30), and exhibits a buffering effect.
 粘性流体36は、一般的なオイルダンパーに用いられるグリース等の流体であり、シリンダー30内をほぼ満たすように充填されている。この粘性流体36は、リード31が進退することでこれに連結するヘッド32がシリンダー30内を移動した際、このヘッド32の開口32c内を通って、このヘッド32の移動方向と反対方向へ相対的に流動する。 The viscous fluid 36 is a fluid such as grease used for a general oil damper, and is filled so as to almost fill the inside of the cylinder 30. When the head 32 connected to the lead 31 moves in the cylinder 30 as the reed 31 moves back and forth, the viscous fluid 36 passes through the opening 32c of the head 32 and moves in a direction opposite to the moving direction of the head 32. Fluidly.
 その際、シリンダー30の断面積より十分に小さい面積の開口32cを通ることで、ヘッド32に対して抵抗力を付与し、このヘッド32の移動に対して緩衝効果を発揮する。特に、ヘッド32の急激な後退移動に際しては、開口32cを相対的に通過する粘性流体の付勢力によって前記バルブ34が弾性変形し、開口32cをより多く塞ぐようになるため、緩衝効果がより高まる。すなわち、このような粘性流体の付勢力を受けると、バルブ34の外周部34aは弾性変形されて外側に拡がる。これによって、バルブ34が開口32cのほぼ全域を塞ぐ(覆う)。したがって、開口32cが狭くなることにより、粘性流体36が開口32c内を相対的に通過することが妨げられるため、緩衝効果が高まる。 At that time, resistance is applied to the head 32 by passing through the opening 32c having an area sufficiently smaller than the cross-sectional area of the cylinder 30, and a buffering effect is exerted against the movement of the head 32. Particularly, when the head 32 is suddenly moved backward, the valve 34 is elastically deformed by the biasing force of the viscous fluid relatively passing through the opening 32c and closes the opening 32c more, so that the buffering effect is further enhanced. . That is, when receiving the biasing force of such a viscous fluid, the outer peripheral portion 34a of the valve 34 is elastically deformed and spreads outward. As a result, the valve 34 closes (covers) almost the entire area of the opening 32c. Accordingly, the narrowing of the opening 32c prevents the viscous fluid 36 from relatively passing through the opening 32c, thereby increasing the buffering effect.
 さらに、このように外周部34aが弾性変形することにより、外周部34aの外周縁の一部がシリンダー30の内面に摺動するため、これによっても緩衝効果が高まる。
 また、このような緩衝効果は、前記コイルスプリング35による緩衝効果とは別に発揮されるため、これら粘性流体36とコイルスプリング35とによる緩衝効果が組み合わされる。そのため、ダンパー3は、ヘッド32の急激な後退移動に際して、特に良好な緩衝効果を発揮してヘッド32の急激な後退移動をより緩やかな後退移動に変化させる。
Furthermore, since the outer peripheral portion 34a is elastically deformed in this way, a part of the outer peripheral edge of the outer peripheral portion 34a slides on the inner surface of the cylinder 30, and this also increases the buffering effect.
Further, since such a buffering effect is exhibited separately from the buffering effect by the coil spring 35, the buffering effect by the viscous fluid 36 and the coil spring 35 is combined. Therefore, the damper 3 exhibits a particularly good buffering effect when the head 32 is suddenly moved backward, and changes the rapid backward movement of the head 32 to a gentler backward movement.
 このような本実施形態のスライドユニット1は、例えば図8に示すように、タンス等の家具の抽斗(移動体)51を収納する収納部(固定体)50に取り付けられて用いられる。図8の例では、収納部50の奥側の左右両側に、それぞれスライドユニット1がネジ等によって取り付けられている。一方、抽斗51には、その底面の両側に可動レール52が取り付けられている。この可動レール52は、収納部50の底板の両側に取り付けられた固定レール53上を、その前後方向(進退方向)に抽斗51を走行させるための部材である。また、この可動レール52の後端部(収納部50の奥側の端部)に、図1A中の二点鎖線で示すように、下方に向かって突出する係合ピン54を有した係合部材55が取り付けられている。 For example, as shown in FIG. 8, the slide unit 1 according to this embodiment is used by being attached to a storage unit (fixed body) 50 that stores a drawer (moving body) 51 of furniture such as a chiffon. In the example of FIG. 8, the slide units 1 are respectively attached to the left and right sides on the back side of the storage unit 50 with screws or the like. On the other hand, a movable rail 52 is attached to both sides of the bottom surface of the drawer 51. The movable rail 52 is a member for running the drawer 51 in the front-rear direction (forward and backward direction) on fixed rails 53 attached to both sides of the bottom plate of the storage unit 50. Further, as shown by a two-dot chain line in FIG. 1A, an engagement pin 54 that protrudes downward is provided at the rear end portion (the end portion on the back side of the storage portion 50) of the movable rail 52. A member 55 is attached.
 この係合部材55の係合ピン54は、抽斗51が収納部50内に収められている状態では、スライドユニット1のスライダー5の一対の挟持片16、16間に挟持され、係合している。また、収納部50から抽斗51を引き出した際には、係合ピン54はスライダー5の挟持片16、16間から外れている。 The engaging pin 54 of the engaging member 55 is sandwiched and engaged between the pair of sandwiching pieces 16 and 16 of the slider 5 of the slide unit 1 in a state where the drawer 51 is housed in the housing portion 50. Yes. Further, when the drawer 51 is pulled out from the storage unit 50, the engaging pin 54 is detached from between the sandwiching pieces 16, 16 of the slider 5.
 すなわち、本実施形態のスライダーユニット1は、図1Aおよび図1Bに示したように、スライダー5の挟持片16、16間から係合ピン54から外れた状態(収納部50から抽斗51が引き出された状態)では、スライダー5が収納部50の開口側に前進した状態となっており、反転バネ6によって付勢されている。したがって、スライダー5の上突条21及び下突条(図示せず)がそれぞれに係合する上ガイド溝15、下ガイド溝11の先端において係止することによって、スライダー5の前進が停止させられる。よって、スライダー5は、反転バネ6による付勢力によってロックされた状態(図1Aおよぶ図1Bに示した状態)に保持される。 That is, in the slider unit 1 of the present embodiment, as shown in FIGS. 1A and 1B, the slider 51 is detached from the engagement pin 54 between the holding pieces 16 and 16 of the slider 5 (the drawer 51 is pulled out from the storage portion 50. The slider 5 is in a state of being advanced toward the opening side of the storage portion 50 and is urged by the reversing spring 6. Accordingly, the forward movement of the slider 5 is stopped when the upper protrusion 21 and the lower protrusion (not shown) of the slider 5 are engaged with each other at the tips of the upper guide groove 15 and the lower guide groove 11. . Therefore, the slider 5 is held in a locked state (the state shown in FIGS. 1A and 1B) by the urging force of the reversing spring 6.
 このように抽斗51が引き出された状態から、この抽斗51を収納部50内に収めるために抽斗51を押し入れると、抽斗51はその可動レール52が固定レール53に案内されて奥側に移動する。そして、可動レール52の後端部に取り付けられた係合部材55の係合ピン54が、スライダー5の挟持片16、16内に案内される。そして、さらに抽斗51が押し入れられると、係合ピン54がスライダー5を押圧することによって、スライダー5は後退する。 When the drawer 51 is pushed in from the state in which the drawer 51 is pulled out in this way in order to store the drawer 51 in the storage unit 50, the movable rail 52 is guided by the fixed rail 53 and moved to the back side. To do. Then, the engagement pin 54 of the engagement member 55 attached to the rear end portion of the movable rail 52 is guided into the holding pieces 16 and 16 of the slider 5. When the drawer 51 is further pushed in, the engagement pin 54 presses the slider 5 so that the slider 5 moves backward.
 その際、スライダー5は反転バネ6によって収納部50の開口側に付勢されているため、抽斗51の押し入れには僅かながら負荷がかかる。
 このような負荷に抗して抽斗51をさらに押し入れると、スライダー5がさらに後退し、スライダー5側の取付孔19(取付部)の位置が、図2Aおよび図2Bに示すように、前述した反転バネ6の反転ポイントを通過する。すると、反転バネ6はその付勢方向を反転させ、スライダー5を後退させる方向(抽斗51を押し入れる方向)に付勢する。したがって、前述した反転バネ6による負荷はなくなるが、スライダー5はダンパー3のリード31に連結していることから、スライダー5の後退に連動してダンパー3がその緩衝効果を発揮する。そのため、スライダー5の急激な後退が妨げられる。
At that time, since the slider 5 is urged toward the opening side of the storage portion 50 by the reversing spring 6, a slight load is applied to the insertion of the drawer 51.
When the drawer 51 is further pushed against such a load, the slider 5 is further retracted, and the position of the mounting hole 19 (mounting portion) on the slider 5 side is as described above as shown in FIGS. 2A and 2B. Passes the reversal point of the reversal spring 6. Then, the reversing spring 6 reverses the urging direction and urges the slider 5 in the direction in which the slider 5 moves backward (the direction in which the drawer 51 is pushed in). Therefore, although the load by the reversing spring 6 described above is eliminated, the slider 5 is coupled to the lead 31 of the damper 3, so that the damper 3 exhibits its buffering effect in conjunction with the backward movement of the slider 5. Therefore, the rapid retreat of the slider 5 is prevented.
 すなわち、スライダー5の後退に伴ってリード31が後退すると、図9に示すように、ヘッド32がシリンダー30内を後退する。すると、ヘッド32はコイルスプリング35を押し縮めることから、このコイルスプリング35の反力(付勢力)を受ける。また、前述したように粘性流体36が、図9中の矢印で示すように、ヘッド32の開口32c(図6参照)を通ってヘッド32と反対の方向に相対的に流動することにより、ヘッド32はこの粘性流体36によっても付勢力を受ける。したがって、ヘッド32は、コイルスプリング35による緩衝効果と粘性流体36による緩衝効果との両方を同時に受けることによって、その後退の速度がより大きく減速する。これにより、抽斗51の急激な後退が抑制される。 That is, when the lead 31 moves backward as the slider 5 moves backward, the head 32 moves backward in the cylinder 30 as shown in FIG. Then, since the head 32 compresses and contracts the coil spring 35, the head 32 receives a reaction force (biasing force) of the coil spring 35. Further, as described above, the viscous fluid 36 relatively flows in the direction opposite to the head 32 through the opening 32c (see FIG. 6) of the head 32 as indicated by the arrow in FIG. 32 is also biased by this viscous fluid 36. Therefore, the head 32 receives both the buffering effect by the coil spring 35 and the buffering effect by the viscous fluid 36 at the same time, so that the retreating speed is greatly reduced. Thereby, the rapid retreat of the drawer 51 is suppressed.
 また、抽斗51を勢いよく閉めて急激に後退させた場合、図10に示すようにバルブ34が弾性変形し、前述したようにヘッド32の開口32c(図6参照)の大半部がバルブ34によって塞がれる(覆われる)。これにより、粘性流体36の流動性が低下し、粘性流体36による緩衝効果が一層高まる。よって、特に抽斗51を急激に後退させた場合には、ダンパー3による緩衝効果も高まることから、抽斗51は急激な後退が抑制される。したがって、この急激な後退(閉動作)に伴って生じる衝撃および騒音、繰り返しの閉動作で生じる衝撃に伴う抽斗51および収納部50の損傷を確実に防止する。 In addition, when the drawer 51 is closed vigorously and retracted rapidly, the valve 34 is elastically deformed as shown in FIG. 10, and the most part of the opening 32c (see FIG. 6) of the head 32 is caused by the valve 34 as described above. It is blocked (covered). Thereby, the fluidity | liquidity of the viscous fluid 36 falls and the buffer effect by the viscous fluid 36 increases further. Therefore, especially when the drawer 51 is retracted rapidly, the buffering effect of the damper 3 is also increased, and thus the drawer 51 is prevented from abruptly retracting. Therefore, it is possible to reliably prevent damage to the drawer 51 and the storage unit 50 due to the impact and noise caused by this sudden retreat (closing operation) and the impact caused by repeated closing operations.
 そして、このような緩衝効果に抗してさらに抽斗51を押し入れて閉じると、前記係合ピン54に押圧されてスライダー5は、図3Aおよび図3Bに示すように、上突条21と上ガイド溝15、下突条と下ガイド溝11によって規定された終端位置まで後退する。また、その状態でダンパー3は、図9に示したように、リード31の連結孔31bを形成する大径部31cが蓋部33に当接することで、後退が不能になる。そして、その状態でスライダー5、反転バネ6によって付勢される。したがって、スライダー5は反転バネ6による付勢力によってロックされた状態(図3Aおよび図3Bに示した状態)に保持される。 Then, when the drawer 51 is further pushed in and closed against such a buffering effect, the slider 5 is pressed by the engagement pin 54, and the upper protrusion 21 and the upper guide are moved as shown in FIGS. 3A and 3B. It retracts to the end position defined by the groove 15, the lower protrusion and the lower guide groove 11. Further, in this state, as shown in FIG. 9, the damper 3 cannot be retracted when the large-diameter portion 31 c forming the connection hole 31 b of the lead 31 comes into contact with the lid portion 33. In this state, the slider 5 and the reversing spring 6 are urged. Therefore, the slider 5 is held in a locked state (the state shown in FIGS. 3A and 3B) by the urging force of the reversing spring 6.
 また、このように抽斗51が閉じられた状態から、これを引き出した場合には、スライダー5は前記と逆に動作し、図3Aおよび図3Bに示した状態から図2Aおよび図2Bに示した状態を経て、図1Aおよび図1Bに示した状態になる。その際、ダンパー3では、スライダー5の前進に対して抵抗する力が粘性流体36によって発揮されるが、コイルスプリング35による付勢力はスライダー5を前進させる方向に作用するため、これらの力はほぼ相殺される。したがって、抽斗51を引き出す際には、ダンパー3はその緩衝機能をほとんど発揮しない。 Further, when the drawer 51 is pulled out from the closed state as described above, the slider 5 operates in the reverse direction to the above, and the state shown in FIGS. 3A and 3B is shown in FIGS. 2A and 2B. After the state, the state shown in FIGS. 1A and 1B is obtained. At this time, in the damper 3, a force that resists the advance of the slider 5 is exerted by the viscous fluid 36, but since the urging force of the coil spring 35 acts in the direction of moving the slider 5 forward, these forces are almost equal. Offset. Therefore, when the drawer 51 is pulled out, the damper 3 hardly exhibits its buffer function.
 このようなスライダーユニット1は、スライダー5を有するスライダー本体2と、このスライダー本体2の所定方向への移動に抗してその移動エネルギーを減衰させるダンパー3とを備えている。そのため、抽斗51の閉動作の際の衝撃を、スライダー本体2を介してダンパー3で緩和・吸収することができる。また、ベース4とスライダー5との間に取り付けられた反転バネ(弾性部材)6が、これらベース4とスライダー5との相対移動によって弾性変形するとともに反転することで弾性復帰する。そのため、これらベース4とスライダー5との相対位置に基づき、抽斗51が開くのを防止するロック機能と、この抽斗51が開いている際にスライダー本体2をその状態に保持するロック機能とを、共に実現する。 Such a slider unit 1 includes a slider body 2 having a slider 5 and a damper 3 that attenuates the movement energy against the movement of the slider body 2 in a predetermined direction. Therefore, the shock at the time of the closing operation of the drawer 51 can be reduced and absorbed by the damper 3 through the slider body 2. Further, the reversing spring (elastic member) 6 attached between the base 4 and the slider 5 is elastically deformed and reversed by the relative movement of the base 4 and the slider 5 to be elastically restored. Therefore, based on the relative position between the base 4 and the slider 5, a lock function for preventing the drawer 51 from opening, and a lock function for holding the slider body 2 in this state when the drawer 51 is open, Realize together.
 よって、このスライドユニット1は、前記の二つのロック機能を反転バネ6が併せ持ち、さらに前進と後退とを切り替えるためのクラッチの機能も有する。その結果、スライドユニット全体に必要な部品点数が少なくなる為、スライドユニット自体に要するスペースが小さくて済み、さらにスライドユニットを容易に組み立てることができる。
 また、このスライドユニット1は、スライダー本体2とダンパー3と反転バネ6とが一体に組み立てられてユニット化されている。そのため、家具の収納部等へのスライドユニットの取付けが極めて容易になり、メンテナンスも行い易くなる。
Therefore, the slide unit 1 has the above two locking functions by the reversing spring 6 and also has a clutch function for switching between forward movement and backward movement. As a result, since the number of parts required for the entire slide unit is reduced, the space required for the slide unit itself can be reduced, and the slide unit can be easily assembled.
The slide unit 1 is unitized by assembling a slider body 2, a damper 3, and a reversing spring 6 together. For this reason, it is very easy to attach the slide unit to the furniture storage section or the like, and it is easy to perform maintenance.
 また、ダンパー3が、シリンダー30内にコイルスプリング35と粘性流体36とを有し、粘性流体36がヘッド32の開口32cを通って相対的に移動するとともに、これら開口32cをバルブ34で塞ぐように構成されている。そのため、特にスライダー5(スライダー本体2)がダンパー3側に急激に移動し、リード31がシリンダー30の底部30a側に移動した場合に、バルブ34が弾性変形して前記開口32cの一部を覆う。これにより、シリンダー30の底部30a側の粘性流体35が、前記開口32cを通ってシリンダー30の蓋部33側に相対的に移動するのが妨げられる。その結果、シリンダー30の底部30a側へのヘッド32の移動が抑制され、このヘッド32に連結するリード31の前記底部側への移動も抑制される。したがって、このダンパー3は、抽斗51の閉動作の際の衝撃を、より良好に緩和・吸収することができる。 The damper 3 has a coil spring 35 and a viscous fluid 36 in the cylinder 30, and the viscous fluid 36 moves relatively through the opening 32 c of the head 32 and closes the opening 32 c with the valve 34. It is configured. Therefore, especially when the slider 5 (slider body 2) moves suddenly toward the damper 3 and the lead 31 moves toward the bottom 30a of the cylinder 30, the valve 34 is elastically deformed to cover a part of the opening 32c. . This prevents the viscous fluid 35 on the bottom 30a side of the cylinder 30 from moving relative to the lid 33 side of the cylinder 30 through the opening 32c. As a result, the movement of the head 32 to the bottom 30a side of the cylinder 30 is suppressed, and the movement of the lead 31 connected to the head 32 to the bottom side is also suppressed. Therefore, the damper 3 can more effectively mitigate and absorb the impact when the drawer 51 is closed.
