本発明は、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（スライド状態）から収納位置（最終所定位置）まで完全に移動させなくても、一定位置まで移動されるとあとは自動的に家具本体等の固定側部材に引き込まれると共に、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、地震時等に移動側部材が不用意に固定側部材から飛び出すのを防止する移動側部材の引き込み装置に関するものである。 The present invention moves a movable member such as a drawer part of furniture, a slide shelf such as a display shelf, etc., to a certain position without completely moving it from the drawer state (slide state) to the storage position (final predetermined position). After that, it will be automatically pulled into the fixed side member such as the furniture body, and the moving side member will be prevented from bouncing when moving the moving side member to the fixed side member vigorously, or at the time of transportation, earthquake The present invention relates to a retracting device for a moving side member that prevents the moving side member from inadvertently jumping out of the fixed side member.
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、移動側部材を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、地震時に不都合が発生する原因となっていた。
この問題を解決するため、固定側部材に連結された固定側メンバーの後端近傍内側に移動側部材が連結された移動側メンバーの引き込み装置を設け、固定側メンバーと移動側メンバー等からなるスライドレールの収納方向に向けたスライドにより係合可能な係合部を移動側メンバーの後端部に設け、引き込み装置の内側には、スライド部材と共に係合ピンを引き込むバネを備え、移動側メンバーを収納終端位置近くまで収納すると係合部が係合ピンに係合して移動側メンバーを引き込み、一定以上の長さに移動側メンバーを引き出すと係合部が係合ピンの係合が外れて、スライド部材と係合ピン手前側に係止させる構成を有し、引出し部の不完全な収納、移動側メンバー（引出し部）を収納する時に生じる引出し部の跳ね返り、運搬時における家具の傾きによる引出し部の飛び出し、さらに地震時の振れによる引出し部の飛び出しを防止する引き込み機能付きスライドレールが提供されている。（例えば特許文献１参照。）
When the moving side member such as the drawer portion is stored in the stationary side member such as the furniture body, if the moving side member is stored vigorously, the moving side member may not be completely stored due to the rebound at the time of storage. In some cases, it was not completely stored from the beginning, which caused inconvenience during transportation of furniture and during earthquakes.
In order to solve this problem, a retracting device for the moving side member connected to the moving side member is provided inside the vicinity of the rear end of the fixed side member connected to the fixed side member. An engaging portion that can be engaged by sliding toward the rail storage direction is provided at the rear end of the moving member, and a spring that pulls the engaging pin together with the sliding member is provided inside the retracting device. When it is stored close to the storage end position, the engaging portion engages with the engaging pin and pulls the moving member, and when the moving member is pulled out to a certain length, the engaging portion disengages the engaging pin. The slide member and the engaging pin are locked on the front side, and the drawer part is incompletely stowed, the drawer part bounces when the moving side member (drawer part) is stowed. Jumping out lead portions due to inclination of the furniture, it is further provided lead-function slide rails to prevent jumping out of the lead portions by vibration during an earthquake.

又、固定側メンバー、移動側メンバーに特別な加工あるいは部材をとりつける必要があり、所定のスライドレールしか使用できず、構造も複雑で部材点数も多く、高価となる欠点があった。
In this case, since the elastic force of the coil spring directly becomes the pulling force of the moving member, the moving member is suddenly pulled when the moving member comes close to the storage end position, so the storage feeling of the drawer portion is not preferable. Further, when the drawer portion is pulled out, the drawing force is required most immediately when the engagement portion and the engagement pin are disengaged, and the state is suddenly released. There is a problem that it is not easy to use.

The restricting protrusion 84 is formed integrally with the elastic pressure contact arm 8.
そして、弾性圧接腕８の引き出し側の端面は、スライドレール１００が最短収縮状態となった時、外側ケース５２の外側上壁５２１の内面に当接して、弾性圧接腕８が所定範囲を超えて下方に回動するのを防止するストッパー用傾斜面８５が形成され、ストッパー用傾斜面８５と下方に対称に、外側ケース５２の引き出し側端部下面の逃し用傾斜面８６が形成され、弾性圧接腕８の収納側端部には、引き出し時に固定側メンバー１の上折曲縁１１の上面に接触しながら回転する金属製の回転ローラー８７が回転自在に取付けられている。
なお、回転ローラー８７の材質は、固定側メンバー１の上折曲縁１１や後述する引き込み力受動部材７の案内傾斜面７２の上面に接触しながら回転するものであればよく、その材質は金属製に限られず、例えば樹脂製であってもよいことは言うまでもない。
When the slide rail 100 is in the shortest contracted state, the end surface on the drawer side of the elastic pressure contact arm 8 comes into contact with the inner surface of the outer upper wall 521 of the outer case 52 so that the elastic pressure contact arm 8 exceeds the predetermined range. A stopper inclined surface 85 for preventing downward rotation is formed, and a relief inclined surface 86 on the lower surface of the outer end of the outer case 52 is formed symmetrically with the stopper inclined surface 85 and is elastically welded. A metal rotation roller 87 that rotates while being in contact with the upper surface of the upper bent edge 11 of the stationary member 1 when being pulled out is rotatably attached to the storage side end of the arm 8.
The rotating roller 87 may be made of any material as long as it rotates while contacting the upper bent edge 11 of the fixed member 1 and the upper surface of the guide inclined surface 72 of the retracting force passive member 7 described later. Needless to say, it may be made of resin, for example.
巻きバネ５３は、弾性圧接腕８が連結用ケース５２に回動自在に保持された状態で、
連結側保持筒（図示せず。）に外嵌し、一端が連結用上壁５１１の下面に当接保持され、他端が弾性圧接腕８の回動範囲規制突片８４の上面に当接保持されて、弾性圧接腕８に、回転ローラー８７が引き込み力受動部材７に弾性的に圧接する方向に回動力を付与している。
尚、実施例では、回転ローラー８７は引き出し時に固定側メンバー１の上折曲縁１１の上面に接触しながら回転し、移動側部材が最も引き出された状態でも、固定側メンバー１の上折曲縁１１の引き出し側端端部に位置する構成となっているが、移動側部材がさらにオーバートラベル状態にひきだされ、回転ローラー８７が上折曲縁１１の引き出し側端部よりさらに引き出し方向に位置する場合は、前記回動範囲規制突片８４の下面が、中間メンバー３の移動側中間メンバー３００の上折曲縁３２２の外面に当接移動して、弾性圧接腕８の必要以上の回動を阻止している。
The winding spring 53 is in a state where the elastic pressure contact arm 8 is rotatably held by the connecting case 52.
It is fitted on a connecting side holding cylinder (not shown), one end is in contact with and held on the lower surface of the connecting upper wall 511, and the other end is in contact with the upper surface of the rotation range restricting protrusion 84 of the elastic pressure contact arm 8. The rotating roller 87 is held and elastic force is applied in the direction in which the rotary roller 87 is elastically pressed against the retractable force passive member 7.
In the embodiment, the rotating roller 87 rotates while contacting the upper surface of the upper bent edge 11 of the fixed member 1 when pulled out, and the upper member of the fixed member 1 is bent even when the movable member is pulled out most. Although it is configured to be located at the end of the edge 11 on the drawer side, the moving side member is further drawn in an overtravel state, and the rotating roller 87 is further in the direction of withdrawal than the end of the upper bent edge 11 on the drawer side. When positioned, the lower surface of the rotation range restricting projecting piece 84 abuts on the outer surface of the upper bent edge 322 of the moving side intermediate member 300 of the intermediate member 3 and the elastic pressure contact arm 8 rotates more than necessary. The movement is stopped.
引き込み力受動部材７は、引き出し側端部に固定側メンバー１の上下折曲縁１１、１１内に嵌合する上下嵌合突起７１、７１を有し、引き出し側端部から収納側端部に向かって傾斜する案内傾斜面７２を上端面に有し、移動側部材が固定側部材に対し最終所定位置に達した状態で、回転ローラー８７が嵌入する保持凹部７３を案内傾斜面７２の収納側端部に有している。
符号７４は固定側部材との連結孔を示している。
The pull-in force passive member 7 has upper and lower fitting projections 71 and 71 that fit into the upper and lower bent edges 11 and 11 of the stationary member 1 at the drawer side end, and from the drawer side end to the storage side end. The holding concave portion 73 into which the rotating roller 87 is fitted is provided on the storage side of the guide inclined surface 72 with the guide inclined surface 72 inclined toward the upper end surface and the moving side member reaching the final predetermined position with respect to the fixed side member. At the end.
Reference numeral 74 denotes a connection hole for the fixed side member.
引き込み装置５０は、上記の如く構成され、移動側メンバーが固定側メンバーに対し最終所定位置に達した状態（図１、図６、図８に示す状態）で、引き込み力付加部材５の弾性圧接腕８の回転ローラー８７が保持凹部７３に嵌入し、弾性圧接腕８は巻きバネ５３によって図６で時計廻りの方向に回動力を付与されているので、移動側メンバー（引き込み力付加部材５）は固定側メンバー（引き込み力受動部材７）に所定の保持力で保持された状態を維持する。
次に、保持力以上の力を加えて、移動側メンバーを引き出し側方向に引き出すと、弾性圧接腕８は巻きバネ５３の弾発力に抗して図６で反時計廻りの方向に回動しながら引き出し側に移動し、回転ローラー力８７は案内傾斜面７３から固定側メンバー１の上折曲縁１１（回転ロ−ラー支持部７０）の上面に達し（図４に示す状態）、さらに引き出し側に移動していく。
The pull-in device 50 is configured as described above, and the elastic member of the pull-in force applying member 5 is pressed in a state where the movable member has reached the final predetermined position with respect to the fixed member (the state shown in FIGS. 1, 6, and 8). Since the rotating roller 87 of the arm 8 is fitted into the holding recess 73 and the elastic pressure contact arm 8 is given rotational force in the clockwise direction in FIG. 6 by the winding spring 53, the moving member (retraction force adding member 5). Maintains the state of being held by the fixed member (retraction force passive member 7) with a predetermined holding force.
Next, when a force greater than the holding force is applied and the moving member is pulled out in the pull-out direction, the elastic pressure contact arm 8 rotates counterclockwise in FIG. 6 against the elastic force of the winding spring 53. The rotating roller force 87 reaches the upper surface of the upper bent edge 11 (rotating roller support portion 70) of the fixed member 1 from the guide inclined surface 73 (state shown in FIG. 4). Move to the drawer side.
一方、移動側メンバーが固定側メンバーに対して最終所定位置に近づいて、引き込み力受動部材７の案内傾斜面７２の引き出し側端部に回転ローラー８７が位置すると（図５に示す状態）、弾性圧接腕８の時計廻りの方向の回動力によって移動側メンバーは固定側メンバーに対して最終所定位置まで引き込まれ、回転ローラー８７は保持凹部７３に嵌入し、移動側メンバーは固定側メンバーに対して所定の保持力で保持される。 On the other hand, when the moving side member approaches the final predetermined position with respect to the fixed side member and the rotating roller 87 is positioned at the drawing side end portion of the guide inclined surface 72 of the pulling force passive member 7 (state shown in FIG. 5), the elastic member is elastic. The moving member is drawn into the final position with respect to the fixed member by the rotational force of the pressure arm 8 in the clockwise direction, the rotating roller 87 is fitted into the holding recess 73, and the moving member is moved with respect to the fixed member . It is held with a predetermined holding force.
なお、引込開始位置は、弾性圧接腕８の長さの選択以外に、引き込み力受動部材７の案内傾斜面７２の長さを選択ことによっても選択可能である。すなわち、案内傾斜面の長さを長くすれば、引き込み開始位置はより引き出し側となり、案内傾斜面の長さを短くすれば、引き込み開始位置はより収納側となる。 Incidentally, pull starting position, in addition to selection of the length of the elastic pressure contact arm 8, which is the length of the inclined guide surface 72 of the retraction force receiving member 7 can also be selected by selection. That is, if the length of the guide inclined surface is increased, the pull-in start position becomes closer to the drawer side, and if the length of the guide inclined surface is decreased, the pull-in start position becomes closer to the storage side.
本発明は上記の如く構成されているので、弾発力の異なった巻きバネを選択することにより、引き込み力の強さを選択でき、また、案内傾斜面の傾斜角度をかえることにより引き込みスピードの選択が出来、また、弾性圧接腕の長さ選択することにより、引き込み開始位置を選択する事が出来る。
Since the present invention is configured as described above, the strength of the pull-in force can be selected by selecting a winding spring having a different elasticity, and the pull-in speed can be adjusted by changing the tilt angle of the guide inclined surface. The pull-in start position can be selected by selecting the length of the elastic pressure contact arm .
