Description

本発明は、スライドレールに連結された家具等の引出し部、陳列棚等のスライド棚等の移動側部材を、引出し状態（スライド全開状態）から収納位置（最終収納位置）まで完全に移動させなくても、所定位置まで移動されると、後は自動的に家具本体等の固定側部材に引き込まれ、さらに、移動側部材を固定側部材に勢いよく移動させた時に生じる移動側部材の跳ね返りの防止、あるいは、運搬時、地震時等、固定側部材からの移動側部材の不用意な飛び出しを防止する引込み機能を有するスライドレールに関するものである。 The present invention does not completely move a drawer portion of furniture or the like connected to a slide rail, or a moving side member such as a slide shelf such as a display shelf from a drawer state (slide fully open state) to a storage position (final storage position). However, when it is moved to a predetermined position, it is automatically drawn into the fixed side member such as the furniture body, and the rebound of the moving side member that occurs when the moving side member is vigorously moved to the fixed side member. It relates to a slide rail having a retracting function for preventing or inadvertently popping out a moving side member from a fixed side member during transportation, an earthquake, or the like.

家具本体等の固定側部材に引出し部等の移動側部材を収納する時、移動側部材を勢い良く収納すると、収納時の跳ね返りによって、移動側部材が完全に収納されなかったり、移動側部材が最初から完全に収納されていなかったりする場合があり、家具の運搬時、地震時に、引出し等が固定側部材から飛び出した勢いで、家具等を運搬中に落下させたり、あるいは転倒することで数々の不都合が生じる原因となっていた。
この問題を解決するため、移動側部材が所定位置まで収納されると、後は自動的に家具本体等の固定側部材に引込む、引込み機能を有するスライドレールが幾種類か提供されている。 When storing a moving side member such as a drawer in a fixed side member such as a furniture body, if the moving side member is vigorously stored, the moving side member may not be completely stored or the moving side member may not be completely stored due to the rebound at the time of storage. It may not be completely stored from the beginning, and when the furniture is being transported or in the event of an earthquake, the drawers, etc. may pop out from the fixed side members, causing the furniture to be dropped or overturned during transportation. Was the cause of the inconvenience.
In order to solve this problem, several types of slide rails having a retracting function are provided, which automatically retract the moving side member to a fixed side member such as a furniture body when the moving side member is stored to a predetermined position.

その一つとして、固定側部材あるいは移動側部材のいずれか一方側に引込み部材を設け、引込み部材に対応して他方側に引込み力受動部材を設け、引込み部材は、移動側部材が固定側部材に対して最終所定位置に近づいたとき、引込み力受動部材に一部が弾性的に圧接する圧接機構を有し、引込み力受動部材は、圧接機構の圧接力を、移動側部材を固定側部材に対し最終所定位置となす方向への引込み力に変化させる案内傾斜面を構成するものである。（特許文献１参照） As one of them, a retracting member is provided on either one side of the fixed side member or the moving side member, a pulling force passive member is provided on the other side corresponding to the retracting member, and the moving side member is a fixed side member of the retracting member. The pull-in force passive member has a pressure contact mechanism that elastically press-contacts a part of the pull-in force passive member when approaching the final predetermined position, and the pull-in force passive member applies the pressure contact force of the pressure contact mechanism and the moving side member to the fixed side member. On the other hand, it constitutes a guide inclined surface that changes the pulling force in the direction of the final predetermined position. (See Patent Document 1)

この場合、引込み力受動部材を固定側部材、あるいは移動側部材のいずれかに取り付けなければならず、コストアップにつながる要因となっていた。
さらに、固定側部材あるいは移動側部材と引込み力受動部材は一体ではないので、その連結部分には微妙な段差が生じ、この段差を引込み部材が通過する際、摺動途中に不連続な違和感が発生する原因にもなっていた。
又、引込み部材は、凸状曲面上を接触移動するので、摺動中左右方向に揺動しやすく、摺動操作の円滑な連続性を損なうだけでなく、引込み部材のローラーが脱輪する要因にもなっていた。 In this case, the pull-in force passive member must be attached to either the fixed-side member or the moving-side member, which is a factor leading to an increase in cost.
Further, since the fixed side member or the moving side member and the pulling force passive member are not integrated, a slight step is generated at the connecting portion, and when the pulling member passes through this step, a discontinuous discomfort is felt during sliding. It was also the cause of the occurrence.
Further, since the retracting member moves in contact with the convex curved surface, it easily swings in the left-right direction during sliding, which not only impairs the smooth continuity of the sliding operation, but also causes the roller of the retracting member to come off. It was also.

一方、安価に提供できる引込み機能を有するスライドレールとしては、移動側レールの一方のボール摺動溝の端部やや内側内面から他方のボール摺動溝の端部側内面に向かって傾斜する脚体を有する線バネからなる引込み部材を移動側レールに着脱自在に設けることにより、移動側のレールの摺動途中は、固定側レールのボール摺動溝に弾性脚体が接触し、移動側レールが一定位置に達した状態で、固定側レールの摺動方向側の端部に脚体が当接して、移動側レールを自動的に収納位置まで移動させるものが提供されている。（特許文献２参照）
この場合、固定側レールのボール摺動溝の端部の角部に線バネが当接するので、摩擦抵抗が大きく、円滑な摺動操作が損なわれるだけでなく、固定側レールあるいは線バネの何れか硬度の低い方が磨耗するなど、耐久性に問題があった。 On the other hand, as a slide rail having a retracting function that can be provided at low cost, a leg that inclines from the slightly inner inner surface of one ball sliding groove of the moving side rail toward the end side inner surface of the other ball sliding groove. By providing a retractable member made of a wire spring having a wire spring on the moving side rail so that the elastic leg comes into contact with the ball sliding groove of the fixed side rail while the moving side rail is sliding, the moving side rail is moved. When the fixed position is reached, the leg comes into contact with the end of the fixed side rail on the sliding direction side, and the moving side rail is automatically moved to the storage position. (See Patent Document 2)
In this case, since the wire spring comes into contact with the corner of the end of the ball sliding groove of the fixed side rail, not only the frictional resistance is large and the smooth sliding operation is impaired, but also either the fixed side rail or the wire spring There was a problem with durability, such as wear on the one with lower hardness.

又、他の例としては、少なくとも第一スライド部材と第二スライド部材とを備え、第二スライド部材に取り付けられる引込み機構であって、前記引込み機構は、アクチュエータ（係合体）を案内するスロットをもっているハウジングを具備し、アクチュエータ（係合体）は、ばねにより生み出される力に応じて移動可能であるようにハウジングに取り付けられ、スロットに沿って第一位置と第二位置との間を滑動することができ、ばねにエネルギを蓄積して第一位置に係合されて残ることができる。 Further, as another example, it is a pull-in mechanism having at least a first slide member and a second slide member and attached to the second slide member, and the pull-in mechanism has a slot for guiding an actuator (engagement body). The actuator (engagement body) is attached to the housing so that it can move in response to the force generated by the spring and slides between the first and second positions along the slot. Can accumulate energy in the spring and remain engaged in the first position.

そして、引き出された第一スライド部材が引込まれる時には、第一スライド部材が閉止位置に近づいたとき、第一スライド部材はアクチュエータに係合し、閉止位置の方へ引き続き移動するので、アクチュエータ（係合体）を第一位置から離脱させ、それによりエネルギを蓄積したばねが、アクチュエータ（係合体）、及び係合した第一スライド部材をスロットに沿ってスライドが閉じられる第二位置に滑動させる。
一方、第一スライド部材が、第二スライド部材に対して引き出されるとき、第一スライド部材がアクチュエータ（係合体）を第二位置から第一位置の方へ移動させ、アクチュエータ（係合体）はばねにエネルギを蓄積させ、第一位置で係合される。そして、第一スライド部材はアクチュエータから離脱される構成のものも提供されている。（特許文献３参照） Then, when the pulled out first slide member is pulled in, when the first slide member approaches the closing position, the first slide member engages with the actuator and continues to move toward the closing position, so that the actuator ( The engaging body) is disengaged from the first position, whereby the energy-accumulating spring slides the actuator (engaging body) and the engaged first slide member along the slot to the second position where the slide is closed.
On the other hand, when the first slide member is pulled out with respect to the second slide member, the first slide member moves the actuator (engagement body) from the second position to the first position, and the actuator (engagement body) springs. Energy is stored in and engaged in the first position. The first slide member is also provided so as to be detached from the actuator. (See Patent Document 3)

この場合、ばねの引張り力で第一スライド部材を第二スライド部材に引き込む構成であるから、第一スライド部材がばねの引張り力に抗して（ばねに引張りエネルギを蓄積させながら）引き出され、アクチュエータ（係合体）が第一位置で係合されると、第一スライド部材はアクチュエータから離脱するので、急激に引き出し力が軽くなり、引き出しスピードが速くなって、収納物、展示物等を転倒、落下させる危険があった。
さらに、第一スライド部材が引き出された状態の時、アクチュエータ（係合体）の第一位置での係合状態が不測に外れ、アクチュエータ（係合体）が第二位置移動した状態では、引込み機能が働かない。この状態を、復帰させるためには、手動によって大きな力を負荷し、第一スライドを押し込み、強制的にアクチュエータ（係合体）に第一スライド部材を係合させなければならなかった。 In this case, since the first slide member is pulled into the second slide member by the tensile force of the spring, the first slide member is pulled out against the tensile force of the spring (while accumulating the tensile energy in the spring). When the actuator (engagement body) is engaged at the first position, the first slide member is disengaged from the actuator, so that the pull-out force is suddenly reduced, the pull-out speed is increased, and the stored items, exhibits, etc. are overturned. , There was a danger of dropping it.
Further, when the first slide member is pulled out, the engaged state of the actuator (engaged body) at the first position is unexpectedly disengaged, and when the actuator (engaged body) is moved to the second position, the retracting function is performed. Doesn't work. In order to restore this state, it was necessary to manually apply a large force, push in the first slide, and forcibly engage the first slide member with the actuator (engagement body).

又、簡単な構造でコンパクトに構成でき、耐久性に優れ、円滑な摺動力で、安価に製作でき、故障等の発生も皆無で、操作も容易な引込み機能を有するスライドレールとして、移動側レールの後端部に、固定側レールの折曲縁に形成されたボール摺動溝に弾性的に圧接する圧接子を有する引込み部材を設け、圧接子が圧接する固定側レールのボール摺動溝の後端部所定位置から、移動側レールを引き込む方向に固定側レールの折曲縁を順次傾斜させて、固定側レールのボール摺動溝と同形で、ボール摺動溝に連続する引込み案内路を折曲縁と一体に形成され、引込み部材は移動側レールに先端部が回動自在に枢止され、後端部に設けられた圧接子が固定側レールのボール摺動溝に弾性的に圧接するよう回動力が付与された回動腕と、回動腕に回動力を付与するバネよりなるものが提供されている。（特許文献４参照） In addition, the moving side rail is a slide rail that can be constructed compactly with a simple structure, has excellent durability, can be manufactured at low cost with smooth sliding force, does not cause any trouble, and has a retracting function that is easy to operate. At the rear end, a pull-in member having a pressure welder that elastically press-contacts the ball sliding groove formed on the bent edge of the fixed-side rail is provided, and the ball sliding groove of the fixed-side rail that the pressure welder press-contacts. From the predetermined position at the rear end, the bent edge of the fixed side rail is sequentially inclined in the direction of pulling in the moving side rail, and a lead-in guide path that has the same shape as the ball sliding groove of the fixed side rail and is continuous with the ball sliding groove is provided. The retractable member is integrally formed with the bent edge, the tip of the retractable member is rotatably pivotally fixed to the moving side rail, and the pressure welder provided at the rear end is elastically pressure-welded to the ball sliding groove of the fixed side rail. A rotating arm to which a rotating force is applied and a spring for applying a rotational force to the rotating arm are provided. (See Patent Document 4)

この場合、回動腕は移動側レールに直接枢止されているので、回動腕の回動可能角度は、後端部に設けられた圧接子が固定側レールに圧接できる上下方向の移動範囲に限定される。すなわち、圧接子の上下方向の移動距離が小さい（回動腕の回動可能角度が少ないので、圧接子のスライド方向の移動距離も小さい）ので、引込みストローク（引込み始めから引込み完了までの距離）を大きくするには、引込み案内路を長く構成する必要がある。つまり、引き込み案内路を長く構成すると、引込み力が弱まるだけでなく、引込みストロークを除いたスライドストロークが短くなる。スライドストロークを維持するにはスライドレール全体の長さを長く構成しなければならない。従って、スライドレール全体の長さが長くなると、所定場所に取り付けることができず、引込み機能を断念する結果となっていた。 In this case, since the rotating arm is directly anchored to the moving side rail, the rotatable angle of the rotating arm is the vertical movement range in which the pressure welder provided at the rear end can press contact with the fixed side rail. Limited to. That is, since the vertical movement distance of the pressure welder is small (since the rotatable angle of the rotating arm is small, the movement distance of the pressure connector in the slide direction is also small), the pull-in stroke (distance from the start of pulling to the completion of pulling). It is necessary to make the lead-in guideway longer in order to increase the size. That is, if the pull-in guide path is made long, not only the pull-in force is weakened, but also the slide stroke excluding the pull-in stroke is shortened. The overall length of the slide rail must be increased to maintain the slide stroke. Therefore, if the length of the entire slide rail becomes long, it cannot be attached in a predetermined place, resulting in abandonment of the retracting function.

本発明は、上記問題に鑑み、簡単な構成で、スライドレールの長さに影響を与えず、引込みストロークを長く構成でき、引込み力も低下させることのない、引き込み機能を有するスライドレールを提供することを課題とする。 In view of the above problems, the present invention provides a slide rail having a pull-in function, which has a simple structure, does not affect the length of the slide rail, can have a long pull-in stroke, and does not reduce the pull-in force. Is the subject.

上記課題を解決する為、本発明が第１の手段として構成したところは、移動側レールの後端部に、固定側レールの折曲縁に弾性的に圧接する圧接子を有する引込み部材を設け、圧接子が圧接する固定側レール折曲縁の後端部所定位置から移動側レールを引き込む方向に固定側レールの折曲縁と一体に引き込み案内路を形成した引き込み機能を有するスライドレールにおいて、引き込み部材は、移動側レールに取り付けられ少なくとも一部が移動側レールの収納側端部の外側に突出する連結用支持部材と、一端が連結用支持部材に回動自在に枢止され、他端に圧接子が回動自在に設けられた回動腕と、回動腕に回動力を付与する付勢手段より構成され、回動腕の回動時に、スライドレールの伸長短縮に合わせて圧接子が固定側レールの折曲縁に付勢手段により弾性的に圧接する姿勢と、圧接子が引き込み案内路に付勢手段により弾性的に圧接する姿勢をとるように、回動腕の前記枢止部を連結用支持部材の前記突出部に設けるとともに、引き込み部材は、引き込み部材の連結用支持部材が、少なくとも移動側レールの一対の上下折曲縁間の基材の内面あるいは外面に取り付けられることにより移動側レールに取り付けられるものである。 In order to solve the above problems, where the present invention is configured as the first means, a retracting member having a pressure welder that elastically press-contacts the bent edge of the fixed-side rail is provided at the rear end of the moving-side rail. In a slide rail having a pull-in function in which a pull-in guide path is formed integrally with the bent edge of the fixed-side rail in the direction of pulling in the moving-side rail from a predetermined position at the rear end of the bent edge of the fixed-side rail to which the pressure welder is in pressure contact. The pull-in member includes a connecting support member that is attached to the moving side rail and at least a part of which protrudes to the outside of the storage side end of the moving side rail, and one end rotatably pivotally fixed to the connecting support member and the other end. It is composed of a rotating arm rotatably provided with a pressure welder and an urging means for applying rotational power to the rotating arm. When the rotating arm rotates, the pressure rail is extended and shortened according to the extension and shortening of the slide rail. The pivot stop of the rotating arm so that the rail is elastically pressed against the bent edge of the fixed side rail by the urging means and the pressure welder is elastically pressed against the retractable guide path by the urging means. Rutotomoni provided parts on the projecting portion of the connecting support member, pulling member draws connecting support member member is attached to the inner surface or the outer surface of the substrate between the pair of upper and lower bent edge of at least the movable rail As a result, it can be attached to the moving side rail .

上記課題を解決する為、本発明が第２の手段として構成したところは、上記第１の手段としての構成に加え、スライドレールの最短収縮状態で圧接子は引き込み案内路下向き方向の端部に圧接し、引き込み案内路は、圧接子が圧接し、移動側レールを引き込む方向に突出し順次円弧状に変形するように形成されように形成されているものである。 In order to solve the above problems, the present invention is configured as the second means. In addition to the configuration as the first means, the pressure welder is placed at the end of the pull-in guide path in the downward direction in the shortest contracted state of the slide rail. The pressure welding and the pull-in guide path are formed so that the pressure welding element is pressure-welded, protrudes in the direction in which the moving side rail is pulled in, and is sequentially deformed into an arc shape .

本発明の第１の手段として構成したところによると、一端に圧接子が回動自在に設けられた回動腕の他端が、連結用支持部材の移動側レールから上下方向のいずれかに突出する突出側の端部に回動自在に枢止されているので、回動腕を、ほぼ水平姿勢からほぼ垂直姿勢の範囲で回動可能に配設することができるので、圧接子は、上下方向からスライド方向に順次移動できるから、引き込み案内路がスライド方向に短くても、引き込みストロークを長く構成することができるので、スライドレール全体の長さを大きくしなくても、必要なスライドストロークを得ることができる。 According to the first means of the present invention, the other end of the rotating arm, which is provided with a pressure welder rotatably at one end, protrudes in either the vertical direction from the moving side rail of the connecting support member. Since it is rotatably pivotally stopped at the end on the protruding side, the rotating arm can be rotatably arranged in a range from a substantially horizontal posture to a substantially vertical posture, so that the pressure welder can be moved up and down. Since it can be moved sequentially from the direction to the slide direction, even if the pull-in guide path is short in the slide direction, the pull-in stroke can be configured to be long, so that the required slide stroke can be obtained without increasing the length of the entire slide rail. Obtainable.

本発明の第２の手段として構成したところによると、スライドレールの最短収縮状態で、圧接子は円弧状の下向き方向の端部に圧接しているので、スライドレールの最短収縮状態を確実に維持する事が出来る。
また、引き込み案内路が、圧接子が圧接し、移動側レールを引き込む方向に突出し順次円弧状に変形するように形成されているので、簡単な構造で円滑な摺動感覚を得ることが出来るだけでなく、引き込み案内路、固定側レールの上折曲縁が同形で連続して一体に形成されているので、微妙な段差もなく、圧接子が、引込み案内路から上折曲縁にそれぞれ移動する段階（逆の段階でも同じ。）においても何ら違和感を生じることがない。 According to the configuration as the second means of the present invention, in the shortest contracted state of the slide rail, the pressure welder is in pressure contact with the arc-shaped downward end, so that the shortest contracted state of the slide rail is surely maintained. Can be done.
Further, since the lead-in guide path is formed so that the pressure welder press-contacts, projects in the direction of pulling in the moving side rail, and sequentially deforms into an arc shape, a smooth sliding feeling can be obtained with a simple structure. Instead, the lead-in guideway and the upper bend edge of the fixed side rail are formed continuously and integrally in the same shape, so the pressure welder moves from the pull-in guideway to the upper bend edge, respectively, without a slight step. There is no sense of incongruity at the stage of doing (the same is true at the opposite stage).

In a slide rail having a pull-in function in which a pull-in guide path is formed integrally with the bent edge of the fixed side rail in the direction in which the side rail is pulled in, a pull-in member is attached to the moving side rail and at least a part of it is on the storage side of the moving side rail.

It is composed of a spring that applies rotational power to the rotating arm, and the rotating arm can be rotated from a nearly horizontal position to a nearly vertical position while the pressure welder elastically presses against the bent edge of the fixed side rail. In the shortest contracted state of the slide rail, the pressure welder is pressed against the end of the pull-in guide path in the downward direction, and the pull-in guide path is formed in a circular arc shape by projecting in the direction in which the pressure welder press-contacts and pulls in the moving side rail.

第１実施例のスライドレールの基本的構成を図１、図６に基づいて説明する。
スライドレール１００は、家具等の本体の内面に連結ネジ等で連結される固定側レール１と、固定側レール１に対し、固定側ボール保持板３に回転自在に保持された複数個のボール３０・・・を介して摺動自在に設けられた中間レール４と、中間レール４に対し、移動側ボール保持板５に回転自在に保持された複数個のボール５０・・・を介して摺動自在に設けられた移動側レール２と、移動側レール２の後端部に取り付けられた引き込み部材６と、引込み部材６に対応して、固定側レール１に設けられた引き込み案内路７より構成されている。

The intermediate rail 4 slidably provided via ..., And the intermediate rail 4 slides via a plurality of balls 50 ... rotatably held by the moving-side ball holding plate 5. It is composed of a freely provided moving-side rail 2, a pull-in member 6 attached to the rear end of the moving-side rail 2, and a pull-in guide path 7 provided on the fixed-side rail 1 corresponding to the pull-in member 6. Has been done.
Hereinafter, in FIG. 1, the diagonally upward direction on the left side will be described as the drawer side (tip side), and the diagonally downward direction on the right side will be described as the storage side (rear end side).

固定側レール１は、金属製の細長条板の短手両端部を内向き円弧状に折り曲げて形成された内面長手方向（摺動方向）にボール案内溝を有する上下折曲縁１１、１１と、基板１２より断面略Ｃ字形をなし、引き出し側前端部に、基板１２の一部が移動側レール２方向に突出し、固定側ボール保持板３、中間レール４、移動側ボール保持板５等を介して、移動側レール２を最大引き出した状態で停止させ、スライドレール１００を最大伸長となすレール伸長時ストッパー（図示せず。）と、収納側後端部に、基板１２を移動側レール２方向に突出し、中間レール４等を介して、移動側レール２が最も収納された状態で停止させ、スライドレール１００を最短縮小状態となすレール短縮時ストッパー１３０が形成されている。 The fixed side rail 1 includes upper and lower bent edges 11 and 11 having ball guide grooves in the inner surface longitudinal direction (sliding direction) formed by bending both short ends of a metal elongated strip in an inward arc shape. , The cross section is substantially C-shaped from the substrate 12, and a part of the substrate 12 protrudes in the moving side rail 2 direction at the front end on the drawer side, and the fixed side ball holding plate 3, the intermediate rail 4, the moving side ball holding plate 5, etc. The moving side rail 2 is stopped in the state where the moving side rail 2 is pulled out to the maximum, and the substrate 12 is attached to the moving side rail 2 at the rear end of the storage side and the rail extension stopper (not shown) that makes the slide rail 100 the maximum extension. A rail shortening stopper 130 is formed that projects in the direction and stops the moving side rail 2 in the most retracted state via the intermediate rail 4 or the like to bring the slide rail 100 into the shortest reduced state.

移動側レール２は、固定側レール１とほぼ同等の長さで、金属製の細長条板の短手両端部を内向き円弧状に折り曲げて形成された内面長手方向（摺動方向）にボール案内溝を有する上下折曲縁２１、２１と、基板２２より固定側レール１に対向する断面略Ｃ字形に形成されている。

That is, the fixed side vertical bent edges 42, 42 and the fixed side substrate 41 having ball guide grooves in the longitudinal direction (sliding direction) of the outer surface by bending both short ends of the elongated strip made of metal in an outward arc shape. The fixed side intermediate rail formed in a substantially C-shaped cross section and the fixed side intermediate rail are symmetrical with each other, and the short ends of the metal elongated strip are bent in an outward arc shape to form an outward arc shape. It is composed of a moving side intermediate rail formed in a substantially C-shaped cross section consisting of moving side vertical bending edges 43, 43 having ball guide grooves in the sliding direction) and moving side substrate 40, and is composed of a fixed side substrate 41 and a moving side substrate 40.

固定側ボール保持板３は帯条金属板にて中間レール４より所定寸法短くした、固定側レール１と中間レール４間に挿入可能な大きさの基板３１と、固定側レール１と中間レール４の各上下折曲縁１１、１１、４２、４２間に位置する上下突出縁３２、３２より断面略コ字形に形成され、上下突出縁３２、３２の長手方向（摺動方向）数個所でボール３０・・・を回転自在に保持している。 The fixed-side ball holding plate 3 is a strip metal plate that is shorter than the intermediate rail 4 by a predetermined size, and has a size of a substrate 31 that can be inserted between the fixed-side rail 1 and the intermediate rail 4, and the fixed-side rail 1 and the intermediate rail 4. The vertical protruding edges 32, 32 located between the upper and lower bent edges 11, 11, 42, 42 are formed in a substantially U-shaped cross section, and the balls are formed at several points in the longitudinal direction (sliding direction) of the upper and lower protruding edges 32, 32. 30 ... Are rotatably held.

移動側ボール保持板５は帯条金属板にて中間レール４より所定寸法短くした、移動側レール２と中間レール４間に挿入可能な大きさの基板５１と、移動側レール２と中間レール４の各上下折曲縁２１、２１、４３、４３間に位置する上下突出縁５２、５２より断面略コ字形に形成され、突出縁５２、５２の長手方向（摺動方向）数個所でボール５０・・・を回転自在に保持している。 The moving-side ball holding plate 5 is a strip metal plate that is made shorter than the intermediate rail 4 by a predetermined size, and has a size of a substrate 51 that can be inserted between the moving-side rail 2 and the intermediate rail 4. The moving-side rail 2 and the intermediate rail 4 The ball 50 is formed in a substantially U-shaped cross section from the upper and lower protruding edges 52 and 52 located between the upper and lower bent edges 21, 21, 43, and 43, and is formed at several points in the longitudinal direction (sliding direction) of the protruding edges 52 and 52. ... is rotatably held.

スライドレール１００は上記の如く構成され、移動側レール２が固定側レール１に最も収納された状態（最短縮小状態）では、中間レール後端ストッパーが、固定側レール１のレール短縮時ストッパーの前面に当接し、移動側レール２の移動側レール収納時ストッパーが中間レール前端ストッパーの前面に当接し、引き込み部材６が引き込み案内部７の収納側端部に位置している。 The slide rail 100 is configured as described above, and when the moving side rail 2 is most housed in the fixed side rail 1 (shortest reduced state), the intermediate rail rear end stopper is the front surface of the fixed side rail 1 when the rail is shortened. The moving-side rail storage stopper of the moving-side rail 2 abuts on the front surface of the intermediate rail front end stopper, and the pull-in member 6 is located at the storage-side end of the pull-in guide portion 7.

この状態から、移動側レール２を前方に引き出していくと、移動側レール２の移動距離の２分の１の距離だけ移動側ボール保持板５は移動し、中間レール４の移動距離の２分の１の距離だけ固定側ボール保持板３は移動するので、移動側レール後端ストッパーの前面が移動側ボール保持板５の後端に当接し、移動側ボール保持板５の前端が中間レール４の中間レール前端ストッパーの後面に当接して、中間レール４の中間レール後端ストッパーの前面が固定側ボール保持板３の後端に当接し、固定側ボール保持板３の前端が、固定側レール１のレール伸長時ストッパーの後面に当接して、移動側レール２、中間レール４は停止し、スライドレール１００は最大伸長状態となる。 When the moving side rail 2 is pulled forward from this state, the moving side ball holding plate 5 moves by a distance of half the moving distance of the moving side rail 2, and the moving side ball holding plate 5 moves by 2 minutes of the moving distance of the intermediate rail 4. Since the fixed side ball holding plate 3 moves by the distance of 1, the front end of the moving side rail rear end stopper abuts on the rear end of the moving side ball holding plate 5, and the front end of the moving side ball holding plate 5 is the intermediate rail 4. The front end of the intermediate rail rear end stopper of the intermediate rail 4 abuts on the rear end of the fixed side ball holding plate 3, and the front end of the fixed side ball holding plate 3 abuts on the fixed side rail. When the rail of 1 is extended, it comes into contact with the rear surface of the stopper, the moving side rail 2 and the intermediate rail 4 are stopped, and the slide rail 100 is in the maximum extended state.

引込み案内路７は、固定側レール１の上折曲縁１１の後端側所定位置から、移動側レール２を引き込む方向に固定側レール１の基板１２から後方に突出する上折曲縁１１を順次円弧状に変形させた形状で、固定側レール１の上折曲縁１１と断面同形で、上折曲縁１１に連続して上折曲縁１１と一体に形成されている。 The lead-in guide path 7 has an upper bent edge 11 projecting rearward from the substrate 12 of the fixed side rail 1 in a direction in which the moving side rail 2 is pulled in from a predetermined position on the rear end side of the upper bent edge 11 of the fixed side rail 1. The shape is sequentially deformed into an arc shape, has the same cross-sectional shape as the upper bent edge 11 of the fixed side rail 1, and is formed continuously with the upper bent edge 11 and integrally with the upper bent edge 11.

すなわち、固定側レール１の上折曲縁１１を残して、基板１２と下折曲縁１１の後端部を、前後方向に所定寸法切り落して加工用切り落とし部７１が形成された後、残った固定側レール１の上折曲縁１１を４分の１円弧状に変形されて、固定側レール１の上折曲縁１１の外形と同形で、上折曲縁１１の後端に連続して上折曲縁１１と一体に形成されたものである。 That is, the upper bent edge 11 of the fixed side rail 1 is left, and the rear end portion of the substrate 12 and the lower bent edge 11 is cut off by a predetermined size in the front-rear direction to form the cut-off portion 71 for processing, and then remains. The upper bent edge 11 of the fixed side rail 1 is deformed into a quarter arc shape, and has the same shape as the outer shape of the upper bent edge 11 of the fixed side rail 1 and is continuous with the rear end of the upper bent edge 11. It is formed integrally with the upper bent edge 11.

尚、実施例では、引き込み案内路７は、固定側レール１の高さ寸の法（基板１２の高さを半径とした４分の１円弧状に形成されているが、半径（曲率半径）を大きくとれば、弧長は長くなるので、引き込みストロークも長くなる反面、後記する引き込み部材６のバネ６３の付勢力が一定であれば引込みスピードは緩やかとなる。（引き込み力は弱くなる。）
一方、半径（曲率半径）が小さい円弧状とすれば、弧長は短くなるので、引き込みストロークも短くなる反面、後記する引き込み部材６のバネ６３の付勢力が一定であれば引込みスピードは速くなる。（引き込み力は強くなる。） In the embodiment, the lead-in guide path 7 is formed in a quarter arc shape with the height of the substrate 12 as the radius, but the radius (radius of curvature). If is large, the arc length becomes long, so that the pulling stroke becomes long, but on the other hand, if the urging force of the spring 63 of the pulling member 6 described later is constant, the pulling speed becomes slow (the pulling force becomes weak).
On the other hand, if the arc shape has a small radius (radius of curvature), the arc length is shortened, so that the pull-in stroke is also short, but the pull-in speed is high if the urging force of the spring 63 of the pull-in member 6 described later is constant. .. (The pulling force becomes stronger.)

引き込み部材６は、移動側レール２の基板２２の内面に取り付けられ、端部が移動側レール２の上方向の外側に突出する、横向き略Ｌ字型の連結用支持部材６１と、一端が連結用支持部材６１の突出側の上端部に回動自在に枢止され、他端に圧接子８が回動自在に設けられた回動腕６２と、回動腕６２に回動力を付与するバネ６３より構成されている。 The pull-in member 6 is attached to the inner surface of the substrate 22 of the moving side rail 2, and one end is connected to a laterally substantially L-shaped connecting support member 61 whose end protrudes outward in the upward direction of the moving side rail 2. A rotating arm 62 that is rotatably pivotally stopped at the upper end of the protruding side of the support member 61 and has a pressure welder 8 rotatably provided at the other end, and a spring that applies rotational power to the rotating arm 62. It is composed of 63.

連結用支持部材６１は、移動側レール２の基板２２の後端部内面に連結され後端部が基板２２の収納側端部後方に突出する連結用突片６１１と、連結用突片６１１の後端から上方に向かって突出し、上端部が移動側レール２の外側に位置する回動腕支持突片６１２より形成され、回動腕支持突片６１２の上端部には連結用枢軸６１０の取り付け孔６１３と、バネ６３の一端を係止するバネ係止突起６１４が設けられている。 The connecting support member 61 is a connecting projecting piece 611 connected to the inner surface of the rear end portion of the substrate 22 of the moving side rail 2 and the rear end portion projecting rearward of the storage side end portion of the substrate 22, and the connecting projecting piece 611. A connecting pivot 610 is attached to the upper end of the rotating arm support projecting piece 612, which protrudes upward from the rear end and has an upper end formed from a rotating arm support projecting piece 612 located outside the moving side rail 2. A hole 613 and a spring locking projection 614 for locking one end of the spring 63 are provided.

回動腕６２は、一端が前記回動腕支持突片６１２の取り付け孔６１３に連結用枢軸６１０、連結用枢軸６１０に外嵌し、バネ６３に内嵌する内筒６００、及び、バネ６３を介して、回動自在に一端が連結され、他端に圧接子８が回転自在に設けられた、移動側レール２の上下折曲縁２１、２１間よりやや長い長さに形成され、回動腕６２の上端部には、バネ係止突起６１４に対応して、バネ６３の他端を係止するバネ端部係止突起６２１が形成されている。 The rotating arm 62 has an inner cylinder 600 and a spring 63 whose one end fits into the mounting hole 613 of the rotating arm support protrusion 612 to fit the connecting pivot 610, the connecting pivot 610, and the spring 63. One end is rotatably connected to the other end, and a pressure welder 8 is rotatably provided at the other end. The length is formed to be slightly longer than between the upper and lower bent edges 21 and 21 of the moving side rail 2 and rotates. At the upper end of the arm 62, a spring end locking projection 621 for locking the other end of the spring 63 is formed corresponding to the spring locking projection 614.

バネ６３は実施例では巻きバネが採用されており、バネ係止突起６１４に一端が係止され、他端がバネ端部係止突起６２１に係止され、それぞれの端部が接近する方向に付勢されている。すなわち、回動腕６２は、図４では後端部が下方に回動する方向（図３では、時計まわりの方向）に付勢された状態となっている。 As the spring 63, a wound spring is adopted in the embodiment, one end is locked to the spring locking projection 614, the other end is locked to the spring end locking projection 621, and the respective ends approach each other. Being urged. That is, the rotating arm 62 is in a state of being urged in the direction in which the rear end portion rotates downward in FIG. 4 (clockwise in FIG. 3).

圧接子８は、実施例では、固定側レール１の上折曲縁１１（引込み案内路７）の外形に一致する外形を有する回転ローラーで形成され、回動取付軸８１、連結孔６２０にて、回動腕６２に回転自在に連結されている。
すなわち、ばね６３の付勢力が一定であれば、枢軸６１０（回動中心点）から圧接子８（回転ローラーの中心）までの長さが長い程、圧接子８が引込み案内路７に圧接する力が弱くなり、引込みスピードは緩やかとなる。 In the embodiment, the pressure welder 8 is formed of a rotating roller having an outer shape that matches the outer shape of the upper bent edge 11 (pull-in guide path 7) of the fixed side rail 1, and is formed by a rotary mounting shaft 81 and a connecting hole 620. , Is rotatably connected to the rotating arm 62.
That is, if the urging force of the spring 63 is constant, the longer the length from the pivot 610 (rotation center point) to the pressure welder 8 (center of the rotating roller), the more the pressure welder 8 presses against the lead-in guide path 7. The force becomes weaker and the pull-in speed becomes slower.

本発明は上記の如く構成され、スライドレール１００の最短収縮状態（図１、図３、図７、図８に示す状態）では、圧接子８は、ばね６３によって引込み案内路７の下端部に弾性的に圧接し、常に移動側レール２を収納側方向に移動するよう付勢しているので、移動側レール２は不用意に引き出し側に引き出されることがなく、スライドレール１００の最短収縮状態を確実に維持することが出来る。 The present invention is configured as described above, and in the shortest contracted state of the slide rail 100 (the state shown in FIGS. 1, 3, 7, and 8), the pressure welder 8 is attached to the lower end of the lead-in guide path 7 by the spring 63. Since the moving side rail 2 is elastically pressure-welded and always urged to move toward the storage side, the moving side rail 2 is not inadvertently pulled out to the pull-out side, and the slide rail 100 is in the shortest contracted state. Can be reliably maintained.

そして、この状態から、移動側レール２が引き出されると、ばね６３の付勢力に抗して回動腕６２は、図３で反時計廻りに回動しながら、移動側レール１と共に前方に移動し、圧接子８は案内路７から固定側レール１の上折曲縁１１の外面後端部に位置する。この時、圧接子８の圧接方向が引込み案内路７の形状変化によって、初期抵抗よりは小さな抵抗で移動側レール２は前方に移動し、次に、圧接子８は固定側レール１の上折曲縁１１に位置し、ばね６３の付勢力による抵抗はほとんどなくなった状態で移動側レール１は最大伸長状態まで引き出される。 Then, when the moving side rail 2 is pulled out from this state, the rotating arm 62 moves forward together with the moving side rail 1 while rotating counterclockwise in FIG. 3 against the urging force of the spring 63. The pressure welder 8 is located at the rear end of the outer surface of the upper bent edge 11 of the fixed side rail 1 from the guide path 7. At this time, the pressure welding direction of the pressure welding element 8 moves forward with a resistance smaller than the initial resistance due to the shape change of the lead-in guide path 7, and then the pressure welding element 8 is folded upward on the fixed side rail 1. The moving side rail 1 is pulled out to the maximum extended state in a state where the resistance due to the urging force of the spring 63 is almost eliminated at the curved edge 11.

すなわち、移動側部材の引き出し始めは、使用者が強めの感覚で引き出す傾向があるのを利用し、引込み案内路７を円弧状とすることで、円滑な摺動感覚を得ることが出来るだけでなく、案内路７、固定側レール１の上折曲縁１１が同形で連続して一体に形成されているので、微妙な段差もなく、圧接子８が、引込み案内路７から上折曲縁１１にそれぞれ移動する段階（逆の段階でも同じ。）においても何ら違和感を生じることがない。
又、スライドレール１００の最短収縮状態で、圧接子８は円弧状の下向き方向の端部に圧接しているので、スライドレール１００の最短収縮状態を確実に維持する事が出来る。 That is, at the beginning of pulling out the moving side member, the user tends to pull out with a strong feeling, and by making the pull-in guide path 7 into an arc shape, it is only possible to obtain a smooth sliding feeling. Since the guide path 7 and the upper bending edge 11 of the fixed side rail 1 have the same shape and are continuously and integrally formed, the pressure welder 8 has an upper bending edge from the lead-in guide path 7 without a slight step. There is no sense of discomfort at the stage of moving to 11 (the same applies to the reverse stage).
Further, since the pressure welder 8 is in pressure contact with the arc-shaped downward end portion in the shortest contracted state of the slide rail 100, the shortest contracted state of the slide rail 100 can be reliably maintained.

そして、スライドレール１００の最大伸長状態から、移動側レール２を押し込んでいくと（移動側レール２と連結された移動側部材を収納していくと）、圧接子８は、固定側レール１の上折曲縁１１の後端から引込み案内路７に位置し、ばね６３の付勢力によって、移動側レール２は自動的に引込まれていく。
そして、ばねの両端部が順次接近することでばね６３の付勢力が弱まるが、引込み案内路７の収納側端部は下向きに突出する形状となっているので、圧接子８の圧接方向がスライドレール１００の摺動方向となり、ばね６３の付勢力の弱まりを補い、確実に最短縮小状態を維持する。 Then, when the moving side rail 2 is pushed in from the maximum extended state of the slide rail 100 (when the moving side member connected to the moving side rail 2 is stored), the pressure welder 8 becomes the fixed side rail 1. It is located in the lead-in guide path 7 from the rear end of the upper bending edge 11, and the moving side rail 2 is automatically pulled in by the urging force of the spring 63.
Then, the urging force of the spring 63 weakens as both ends of the spring approach each other in sequence, but the storage side end of the lead-in guide path 7 has a shape that protrudes downward, so that the pressure welding direction of the pressure welder 8 slides. It becomes the sliding direction of the rail 100, compensates for the weakening of the urging force of the spring 63, and surely maintains the shortest contracted state.

さらに、回動腕６２を、ほぼ水平姿勢からほぼ垂直姿勢の範囲で回動可能に配設しているので、圧接子８は、上下方向からスライド方向に順次移動できるから、引き込み案内路７がスライド方向に短くても、引き込みストロークを長く構成することができるので、スライドレール全体の長さを大きくしなくても、必要なスライドストロークを得ることができる。 Further, since the rotating arm 62 is rotatably arranged in a range from a substantially horizontal posture to a substantially vertical posture, the pressure welder 8 can be sequentially moved from the vertical direction to the sliding direction, so that the pull-in guide path 7 is provided. Since the pull-in stroke can be made long even if it is short in the slide direction, the required slide stroke can be obtained without increasing the length of the entire slide rail.

次に、第２実施例を図９から図１４に基づいて説明する
符号１００は本発明の第２実施例のスライドレールを示し、スライドレール１００は固定側レール１と、ボール５０・・・を回転自在に保持する移動側ボール保持板５を介して固定側レール１と互いに摺動自在となした移動側レール２と、移動側レール２の後端部に取り付けられた引込み部材６と、引込み部材６に対応して、固定側レール１に設けられた引込み案内路７より構成されている。
以下、図９において左側斜め下方向を引き出し側（先端側）、右側斜め上方向を収納側（後端側）として説明する。 Next, reference numeral 100, which will be described with reference to FIGS. 9 to 14 of the second embodiment, indicates a slide rail of the second embodiment of the present invention, and the slide rail 100 includes a fixed side rail 1, a ball 50, and so on. The moving side rail 2 that is slidable with the fixed side rail 1 via the moving side ball holding plate 5 that is rotatably held, and the retracting member 6 attached to the rear end of the moving side rail 2 are retracted. Corresponding to the member 6, it is composed of a lead-in guide path 7 provided on the fixed side rail 1.
Hereinafter, in FIG. 9, the diagonally downward direction on the left side will be described as the drawer side (tip side), and the diagonally upward direction on the right side will be described as the storage side (rear end side).

固定側レール１は金属製の細長条板の短手両端部を外向き円弧状に折り曲げて、外面長手方向（摺動方向）にボール案内溝を有する上下折曲縁１１、１１と基板１２からなる断面略Ｃ字形に形成されている。
そして、基板１２の引き出し側前部に一部を移動側レール２方向に突出させて移動側レール２が引き出された状態で、移動側ボール保持板５の後端部が当接するボール保持板後端部ストッパー（図示せず。）が形成されている。
又、引き込み部材６に対応して固定側レール１の上折曲縁１１の後端部を円弧状に折曲げて、上折曲縁１１と一体的に連続する引き込み案内路７が形成されている。 The fixed side rail 1 is formed by bending both ends of a metal elongated strip plate in an outward arc shape from the upper and lower bent edges 11 and 11 having ball guide grooves in the outer longitudinal direction (sliding direction) and the substrate 12. The cross section is formed in a substantially C shape.
Then, in a state where the moving side rail 2 is pulled out by projecting a part of the substrate 12 from the front part on the pulling side in the moving side rail 2 direction, the rear end portion of the moving side ball holding plate 5 comes into contact with the rear of the ball holding plate. An end stopper (not shown) is formed.
Further, the rear end portion of the upper bent edge 11 of the fixed side rail 1 is bent in an arc shape corresponding to the pulling member 6, and a pulling guide path 7 integrally continuous with the upper bent edge 11 is formed. There is.

移動側レール２は、固定側レール１とほぼ同等の長さで、金属製の細長条板の短手両端部を内向き円弧状に折り曲げて形成された内面長手方向（摺動方向）にボール案内溝を有する上下折曲縁２１、２１と、基板２２より断面略Ｃ字形に形成されている。
そして、基板２２の引き出し側端部には、前記固定側レール１方向に突出し、移動側レール２の収納時に固定側レール１の前端に当接する移動側レール収納時ストッパーが形成され、基板２２の収納側端部には、スライドレール１００の最大伸長状態で移動側ボール保持板５の一部に当接する移動側レール後端ストッパー（図示せず。）が形成されている。 The moving side rail 2 has almost the same length as the fixed side rail 1, and is formed by bending both short ends of a metal elongated strip in an inward arc shape and forming a ball in the inner surface longitudinal direction (sliding direction). The upper and lower curved edges 21 and 21 having guide grooves and the substrate 22 are formed in a substantially C-shaped cross section.
Then, at the pull-out side end of the substrate 22, a moving-side rail storage stopper that protrudes in the fixed-side rail 1 direction and comes into contact with the front end of the fixed-side rail 1 when the moving-side rail 2 is stored is formed on the substrate 22. A rear end stopper (not shown) of the moving side rail that comes into contact with a part of the moving side ball holding plate 5 in the maximum extended state of the slide rail 100 is formed at the storage side end portion.

移動側ボール保持板５は、帯条金属板にて固定側レール１、移動側レール２間に挿入可能な大きさで、かつ、固定側レール１の略３分の１程度の長さで、基板５１と、固定側レール１と移動側レール２の上下の折曲縁１１、１１、２１、２１間に突出する基板５１の上下端部に連設された上下の折曲片５２、５２からなり、上下の両折曲片５２、５２の摺動方向の数箇所に複数個のボール５０・・・を回転自在に保持している。 The moving-side ball holding plate 5 has a size that can be inserted between the fixed-side rail 1 and the moving-side rail 2 with a strip metal plate, and has a length of about one-third that of the fixed-side rail 1. From the upper and lower bent pieces 52, 52 connected to the upper and lower ends of the substrate 51 and the upper and lower ends of the substrate 51 protruding between the upper and lower bent edges 11, 11, 21, and 21 of the fixed side rail 1 and the moving side rail 2. Therefore, a plurality of balls 50 ... Are rotatably held at several positions in the sliding direction of the upper and lower bent pieces 52, 52.

すなわち、固定側レール１の上折曲縁１１を残して、基板１２と下折曲縁１１の後端部を、前後方向に所定寸法切り落して加工用切り落とし部７１が形成された後、残った固定側レール１の上折曲縁１１を円弧状に変形させて、固定側レールの上折曲縁１１の外形と同形で、上折曲縁１１の後端に連続して上折曲縁１１と一体に形成されたものである。 That is, the upper bent edge 11 of the fixed side rail 1 is left, and the rear end portion of the substrate 12 and the lower bent edge 11 is cut off by a predetermined size in the front-rear direction to form the cut-off portion 71 for processing, and then remains. The upper bent edge 11 of the fixed side rail 1 is deformed into an arc shape to have the same shape as the outer shape of the upper bent edge 11 of the fixed side rail, and the upper bent edge 11 is continuous with the rear end of the upper bent edge 11. It is formed integrally with.

引き込み部材６は、移動側レール２の基板２１の外面に取り付けられ、収納側端部が移動側レール２の上方の外側に突出する連結用支持部材６１と、一端が連結用支持部材６１の突出側の端部に回動自在に枢止され、他端に圧接子８が回動自在に設けられた回動腕６２と、回動腕６２に回動力を付与するバネ６３より構成されている。 The pull-in member 6 is attached to the outer surface of the substrate 21 of the moving side rail 2, and the connecting support member 61 whose storage side end projectes upward and outward of the moving side rail 2 and one end of the connecting support member 61 projecting. It is composed of a rotating arm 62 rotatably pivotally stopped at the end on the side and a pressure welder 8 rotatably provided at the other end, and a spring 63 for applying rotational power to the rotating arm 62. ..

連結用支持部材６１は、移動側レール２の基板２２の収納側端部外面に連結される連結用基板６１１と、連結用基板６１１の収納側端部上端から収納側に向かって突出し、収納側端部が移動側レール２の外側に位置する回動腕支持突部６１２より形成され、回動腕支持突部６１２には枢軸６１０の取り付け孔が形成され、連結用基板６１１の引き出し側には、バネ６３の一端を保持するバネ保持突起６１４が設けられている。 The connecting support member 61 projects from the upper end of the storage side end of the connecting board 611 to the connecting board 611 connected to the outer surface of the storage side end of the board 22 of the moving side rail 2 toward the storage side. The end is formed from the rotating arm support protrusion 612 located on the outside of the moving side rail 2, the rotating arm support protrusion 612 is formed with a mounting hole for the pivot 610, and the drawing side of the connecting substrate 611 is formed. , A spring holding protrusion 614 for holding one end of the spring 63 is provided.

回動腕６２は、一端が前記回動腕支持突部６１２の付け孔に枢軸６１０を介して、回動自在に一端が連結され、他端に圧接子８が回転自在に設けられた、移動側レール２の上下折曲縁２１、２１間よりやや長い長さに形成され、回動腕６２のやや下端部には、バネ保持突起６１４に対応して、バネ６３の他端を保持するバネ端部保持突起６２１が形成されている。 One end of the rotating arm 62 is rotatably connected to the hole of the rotating arm support protrusion 612 via a pivot 610, and one end is rotatably provided with a pressure welder 8 at the other end. A spring that is formed to have a length slightly longer than between the upper and lower bent edges 21 and 21 of the side rail 2, and that holds the other end of the spring 63 at the slightly lower end of the rotating arm 62 in response to the spring holding protrusion 614. The end holding protrusion 621 is formed.

バネ６３は第２実施例では引っ張りバネが採用されており、バネ保持突起６１４に一端が保持され、他端がバネ端部保持突起６２１に保持され、それぞれの端部が接近する方向に付勢されている。すなわち、回動腕６２は、図１４では収納側端部が下方に回動する方向（図１１では、半時計まわりの方向）に付勢された状態となっている。 A tension spring is adopted as the spring 63 in the second embodiment, one end is held by the spring holding protrusion 614, the other end is held by the spring end holding protrusion 621, and the spring 63 is biased in the direction in which the respective ends approach each other. Has been done. That is, the rotating arm 62 is in a state of being urged in the direction in which the storage side end portion rotates downward in FIG. 14 (counterclockwise direction in FIG. 11).

圧接子８は、実施例では、固定側レール１の上折曲縁１１（引込み案内路７）の外形に一致する外形を有する回転ローラーで形成され、回動取付軸８１、連結孔にて、回動腕６２に回転自在に連結されている。 In the embodiment, the pressure welder 8 is formed of a rotating roller having an outer shape that matches the outer shape of the upper bent edge 11 (pull-in guide path 7) of the fixed side rail 1, and is formed by a rotary mounting shaft 81 and a connecting hole. It is rotatably connected to the rotating arm 62.

第２実施例は上記のごとく構成され、スライドレール１００の最短収縮状態（図９、図１０、図１１、図１２）では、圧接子８は、ばね６３によって引込み案内路７の下端部に弾性的に圧接し、常に移動側レール２を収納側方向に移動するよう付勢しているので、移動側レール２は不用意に前方に引き出されることがなく、スライドレール１００の最短収縮状態を確実に維持することが出来る。 The second embodiment is configured as described above, and in the shortest contracted state of the slide rail 100 (FIGS. 9, 10, 11, 12), the pressure welder 8 is elastically attached to the lower end of the lead-in guide path 7 by the spring 63. Since the moving side rail 2 is always pressure-welded and urged to move in the storage side direction, the moving side rail 2 is not inadvertently pulled forward, and the shortest contracted state of the slide rail 100 is ensured. Can be maintained at.

そして、この状態から、移動側レール２が引き出されると、ばね６３の付勢力に抗して回動腕６２は、図１０で反時計廻りに回動しながら、移動側レール１と共に前方に移動し、圧接子８は案内路７から固定側レール１の上折曲縁１１の外面後端部に位置する。（図１４に示す状態。）この時、圧接子８の圧接方向が引込み案内路７の形状変化によって、初期抵抗よりは小さな抵抗で移動側レール２は前方に移動し、次に、圧接子８は固定側レール１の上折曲縁１１に位置し、ばね６３の付勢力による抵抗はほとんどなくなった状態で移動側レール１は最大伸長状態まで引き出される。 Then, when the moving side rail 2 is pulled out from this state, the rotating arm 62 moves forward together with the moving side rail 1 while rotating counterclockwise in FIG. 10 against the urging force of the spring 63. The pressure welder 8 is located at the rear end of the outer surface of the upper bent edge 11 of the fixed side rail 1 from the guide path 7. (The state shown in FIG. 14) At this time, the moving side rail 2 moves forward with a resistance smaller than the initial resistance due to the shape change of the lead-in guide path 7 in the pressure welding direction of the pressure welding element 8, and then the pressure welding element 8 Is located at the upper bending edge 11 of the fixed side rail 1, and the moving side rail 1 is pulled out to the maximum extended state with almost no resistance due to the urging force of the spring 63.

そして、スライドレール１００の最大伸長状態から、移動側レール２を押し込んでいくと（移動側レール２と連結された移動側部材を収納していくと）、圧接子８は、固定側レール１の上折曲縁１１の後端から引込み案内路７に位置し、ばね６３の付勢力によって、移動側レール２は自動的に引込まれていく。
そして、ばねの両端部が順次接近することでばね６３の付勢力が弱まるが、引込み案内路７の収納側端部は下向きに突出した形状であるから、圧接子８の圧接方向がスライドレール１００の摺動方向となり、ばね６３の付勢力の弱まりを補い、確実に最短縮小状態を維持する。 Then, when the moving side rail 2 is pushed in from the maximum extended state of the slide rail 100 (when the moving side member connected to the moving side rail 2 is stored), the pressure welder 8 becomes the fixed side rail 1. It is located in the lead-in guide path 7 from the rear end of the upper bending edge 11, and the moving side rail 2 is automatically pulled in by the urging force of the spring 63.
Then, the urging force of the spring 63 weakens as both ends of the spring approach each other in sequence, but since the storage side end of the lead-in guide path 7 has a shape that protrudes downward, the pressure welding direction of the pressure welder 8 is the slide rail 100. It becomes the sliding direction of the spring 63, compensates for the weakening of the urging force of the spring 63, and surely maintains the shortest contracted state.
