Description

【０００１】
【発明の属する技術分野】
本発明は、電気ポット、電気炊飯器等の台所用電気器具が載置された載置棚を前後方向に摺動自在に支持するスライドレールに設けられるスライドレールの収納時保持装置に関するものである。
【０００２】
【従来の技術】
従来、家具等の移動時あるいは家具が傾いていたりすると載置棚が不用意に飛び出すことがあった。これを防止するため、スライドレールの移動側レール基板の収納側端部に固定側レール方向に突出し、上下方向に所定寸法を有する移動側移動時ストッパーを形成し、この移動側移動時ストッパーを固定側レールの収納側端部に設けた収納時保持部材に保持するものが提供されている。
そして、この収納時保持部材は、移動側レールの方向でかつ移動側に突出し、移動側方向で順次大きく離間する上下傾斜案内突片と、上下案内突片の収納側に連設され、最も近接する個所の端面が円弧状をなし、その離間寸法が、前記移動側移動時ストッパーの上下方向の寸法より小さめに形成された上下係止突部と、該上下係止突部の収納側に連設され、前記移動側移動時ストッパーの上下方向の寸法よりやや小さめに形成された上下挟持段部と、上下挟持段部の収納側に連設された上下弾性支持突片よりなる上下弾性保持部と、上下弾性保持部に連設された取付部より構成されている。（例えば特許文献１参照。）
【０００３】
そして、載置棚を引き出した時、載置棚の後端から電気ポット、電気炊飯器等の電気器具の電気コードが、左右の固定側レール間に垂れ下がった状態となり、この状態から載置棚を収納しようとすると、上記収納時保持部材が固定側レールから移動側レール方向に突出し、さらに、上下弾性保持部が固定側レールとの間に間隙を有して、先端が爪状となって、移動側方向に突出しているので、垂れ下がったコードが固定側レールと上下弾性保持部間に入り込んだり、あるいは上下弾性保持部に絡み付き、載置棚の収納をスムーズに行う事が出来なかったり、あるいは、絡まったコードを外す際、指先を傷付けたりたりすることがあった。

【００１４】
収納時保持部材５は、上位の如く構成され、固定側収納時ストッパー１３の上下端部と上下の折曲縁１２、１２の収納側端部の隙間に上下の嵌合取付部５１、５１と上下の移動防止突部５４、５４の連設部分を当接し、同時に、上下の嵌合取付部５１、５１を上下の折曲縁１２、１２の端部に当接させた状態から、弾性変形部５７、弾性取付基板５２を弾性変形させながら、固定側レール１内に強制的に押し込み、上下の嵌合取付部５１、５１を上下の折曲縁１２、１２内（ボール摺動溝内）に嵌合すると同時に、上下の移動防止突部５４、５４を上下の折曲縁１２、１２の収納側端面に当接させて取り付られる。
この状態で、上下の嵌合取付部５１、５１と上下の折曲縁１２、１２の嵌合、及び、上下の移動防止突部５４、５４と上下の折曲縁１２、１２の収納側端面との当接、弾性取付基板５２の収納側端面と固定側収納時ストッパー１３の移動側端面との当接によって、収納時保持部材５は不測に固定側レールから脱落することがない。
【００１５】
移動側レール２は、固定側レール1と対向した同形同長に形成され、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にボール案内溝を有する上下の両折曲縁２１、２１と、連結金具等（図示せず。）を介して載置棚と連結される移動側レール基板２２より、断面略Ｃ字形に形成されている。
【００１６】
そして、移動側レール基板２２の移動側端部を固定側レール１方向に折り曲げて形成された移動側収納時ストッパー２３と、移動側レール基板２２の収納側端部を固定側レール１方向に折り曲げて形成された移動側移動時ストッパー２４を有している。
符号２５、２５は、上下の両折曲縁２１、２１の収納側端部に形成され、移動側レール２の収納時、収納時保持部材５の上下の収納時保持部５６、５６を内側に変移させた後、保持用段部５６２、５６２に位置して、移動側レール２の不用意な移動側方向への移動を防止する保持用凹部を示している。
符号２６は移動側移動時ストッパー２４にもうけられたゴム製の緩衝部材を示している。
【００１７】
本発明は、上記の如く構成されており、スライドレールの最大伸長状態で、移動側レール２の移動側移動時ストッパー２４が緩衝部材２６を介して、ボール保持板６の収納側端面に当接し、ボール保持板６の移動側端面は中間レール３（移動側中間レール３００）のボール保持板引き出し時ストッパーに緩衝部材を介して当接し、中間レール３（固定側中間レール３０）のボール保持条板収納時ストッパー３３は、ボール持板４の収納側端面に緩衝部材３４を介して当接し、ボール保持板４の移動側端面は固定側レール１の固定側移動時ストッパーに当接している。
【００１８】
次に上記の状態から、移動側レール２を収納側に移動させると、ボール保持板６は移動側レール２の移動距離の２分の１の移動距離で収納側に移動し、移動側レール２の移動側収納時ストッパー２３が中間レール３（移動側中間レール３００）のボール保持板引き出し時ストッパーに緩衝部材を介して当接する。
次に移動側レール２と中間レール３は共に、収納側方向に移動し、ボール保持板４は、中間レール３の移動距離の２分の１移動距離で、収納側に移動し、やがて、固定側中間レール３０の収納側端部が収納時保持部材５の中間レール挿通部５０を挿通して、ボール保持板収納時ストッパー３３が、固定側レール１の固定側収納時ストッパー１３に緩衝部材３４を介して当接し、同時に移動側レール２の保持用凹部２５、２５は、収納時保持部材５の保持用段部５６２、５６２に位置し、移動側レール２、中間レール３は収納時保持部材５に保持され、スライドレールは最短収縮状態が維持される。
【００１９】
すなわち、移動側レール２の保持用凹部２５、２５が、収納保持部５６、５６の案内傾斜部５６１、５６１に達した状態（図５に示す状態）で、その衝突時の衝撃は弾性変形部５７の切欠部５７１によって緩和され、さらに、収納側に移動するとき、弾性変形部５７の切欠部５７１によって、弾性変形部５７の移動側は容易く弾性変形するので、収納保持部５６、５６の移動側も互いに内側に容易く変移し、保持用凹部２５、２５の案内傾斜部５６１、５６１部分での通過を容易なものにすると共に、移動側レール２の摺動スピードにブレーキ効果をもたらす。
【００２０】
さらに、保持用凹部２５、２５が収納方向に移動すると、収納保持部５６、５６は弾性変形部５７によって、互いに内側に変移し、保持用凹部２５、２５が保持用段部５６２、５６２に達した時、収納保持部５６、５６は弾性変形部５７の弾性によってもとの位置に復帰し、保持用凹部２５、２５を保持する。（図６に示す状態。）
この状態で、弾性変形部５７の収納側端部には切欠部が形成されていないので
、保持用凹部２５、２５が収納保持部５６、５６の移動側端部を通過する以上の摺動力を必要とし、移動側レール３は収納時保持部材に確実に保持される。
又、挿通孔５０によって、中間レール３の長さは収納時保持部材５の摺動方向の大きさに影響されることがないので、収納時保持部材５を設けても、移動側レール２の摺動距離が少なくなることがない。
【００２１】
【発明の効果】
特許請求の範囲の請求項１に記載の発明によれば、収納時保持部材は、固定側レールから移動側レール方向に突出する上下の閉塞部と、上下の収納時保持部間に連設された弾性変形部によって、固定側レール及び上下の収納時保持部間に隙間が発生しないので、垂れ下がったコードが固定側レールと移動側レール間に入り込んだり、収納時保持部に絡み付き、載置棚の収納を疎外することがない。
【００２２】
請求項２に記載の発明によれば、前記効果に加え、固定側レールに嵌合する上下の嵌合取付部と、上下の嵌合取付部間に連設された弾性取付基板を有しているので、収納時保持部材の固定側レールに対する取付けが容易である。さらに、収納時保持部の移動側前端部に、移動側レール側の角部を大きな曲線で処理した案内曲線部が形成されているので、尚、一層、垂れ下がったコードが固定側レールと移動側レール間に入り込んだり、収納時保持部に絡み付き、載置棚の収納を疎外することがない。

BACKGROUND OF THE INVENTION
The present invention relates to a holding device for holding a slide rail provided on a slide rail that slidably supports a mounting shelf on which kitchen appliances such as an electric pot and an electric rice cooker are mounted in the front-rear direction. .
[0002]
[Prior art]
Conventionally, when the furniture is moved or when the furniture is tilted, the placement shelf sometimes pops out carelessly. In order to prevent this, a moving side moving stopper that protrudes in the fixed side rail direction and has a predetermined dimension in the vertical direction is formed at the storage side end of the moving side rail substrate of the slide rail, and this moving side moving stopper is fixed. What is held by the holding member provided at the storage side end of the side rail is provided.
The storage holding member protrudes in the direction of the moving rail and toward the moving side, and is vertically connected to the vertically inclined guide protruding piece that is gradually separated in the moving side direction and the storing side of the vertical guiding protruding piece, and is closest The end surface of the portion to be formed is arc-shaped, and the separation dimension is connected to the upper and lower locking projections formed smaller than the vertical dimension of the stopper when moving on the moving side, and the storage side of the upper and lower locking projections. The upper and lower elastic holding portion is formed by an upper and lower clamping step portion that is provided and is slightly smaller than the vertical dimension of the stopper at the time of moving on the moving side, and an upper and lower elastic support projecting piece continuously provided on the storage side of the upper and lower clamping step portion And an attachment portion provided continuously with the vertical elastic holding portion. (For example, refer to Patent Document 1.)
[0003]
When the mounting shelf is pulled out, the electrical cords of the electric appliances such as the electric pot and the electric rice cooker hang from the left and right fixed rails from the rear end of the mounting shelf. When the storage member is to be stored, the holding member protrudes from the fixed side rail toward the moving side rail, and the vertical elastic holding part has a gap between the fixed side rail and the tip is claw-shaped. Because it protrudes in the moving side direction, the hanging cord enters between the fixed side rail and the vertical elastic holding part, or it gets entangled with the vertical elastic holding part, and the mounting shelf can not be stored smoothly, Or, when removing the entangled cord, the fingertip was sometimes damaged.

Then, a moving side storage stopper 23 formed by bending the moving side end of the moving side rail substrate 22 in the direction of the fixed side rail 1 and a storing side end of the moving side rail substrate 22 in the direction of the fixed side rail 1 are bent. The moving side movement stopper 24 is formed.
Reference numerals 25 and 25 are formed at the storage side end portions of the upper and lower bent edges 21 and 21, and when the moving side rail 2 is stored, the upper and lower storage holding portions 56 and 56 of the storage holding member 5 are placed inside. After the displacement, the holding concave portions that are located on the holding step portions 562 and 562 and prevent the movement-side rail 2 from inadvertently moving in the movement side direction are shown.
Reference numeral 26 denotes a rubber cushioning member provided on the stopper 24 when moving on the moving side.
[0017]
The present invention is configured as described above. In the maximum extension state of the slide rail, the stopper 24 contacts the storage side end surface of the ball holding plate 6 via the buffer member 26 when the moving rail 2 moves. The moving side end surface of the ball holding plate 6 abuts against a stopper when the ball holding plate of the intermediate rail 3 (moving side intermediate rail 300) is pulled out via a buffer member, and the ball holding strip of the intermediate rail 3 (fixed side intermediate rail 30). The plate storage stopper 33 is in contact with the storage side end surface of the ball holding plate 4 via the buffer member 34, and the moving side end surface of the ball holding plate 4 is in contact with the fixed side movement stopper of the fixed rail 1.
[0018]
Next, when the moving side rail 2 is moved from the above state to the storing side, the ball holding plate 6 moves to the storing side by a moving distance that is one half of the moving distance of the moving side rail 2. The moving side storage stopper 23 comes into contact with the stopper when the ball holding plate of the intermediate rail 3 (moving side intermediate rail 300) is pulled out via a buffer member.
Next, both the moving side rail 2 and the intermediate rail 3 move in the storage side direction, and the ball holding plate 4 moves to the storage side at a movement distance of a half of the movement distance of the intermediate rail 3, and eventually becomes fixed. The storage side end of the side intermediate rail 30 is inserted through the intermediate rail insertion portion 50 of the holding member 5 during storage, and the ball holding plate storage stopper 33 is fixed to the fixed side storage stopper 13 of the fixed rail 1 as a buffer member 34. At the same time, the holding recesses 25, 25 of the moving side rail 2 are positioned at the holding step portions 562, 562 of the holding member 5 at the time of storage, and the moving side rail 2 and the intermediate rail 3 are at the time of the holding member at the time of storage. 5, the slide rail is kept in the shortest contracted state.
[0019]
That is, in the state where the holding concave portions 25, 25 of the moving rail 2 reach the guide inclined portions 561, 561 of the storage holding portions 56, 56 (state shown in FIG. 5), the impact at the time of the collision is the elastic deformation portion. When the movement is moved to the storage side, the movement side of the elastic deformation portion 57 is easily elastically deformed by the cutout portion 571 of the elastic deformation portion 57, so that the movement of the storage holding portions 56, 56 is reduced. The sides also easily shift inward from each other, facilitating passage through the guide inclined portions 561 and 561 of the holding recesses 25 and 25, and providing a braking effect on the sliding speed of the moving rail 2.
[0020]
Further, when the holding recesses 25 and 25 are moved in the storage direction, the storage holding portions 56 and 56 are moved inward by the elastic deformation portion 57, and the holding recesses 25 and 25 reach the holding step portions 562 and 562. At this time, the storage and holding portions 56 and 56 return to their original positions due to the elasticity of the elastic deformation portion 57 and hold the holding concave portions 25 and 25. (The state shown in FIG. 6)
In this state, since the cutout portion is not formed at the storage side end of the elastic deformation portion 57, the holding recesses 25, 25 have a sliding force that exceeds the moving side end of the storage holding portions 56, 56. Necessary, the movable rail 3 is securely held by the holding member when stored.
Further, the length of the intermediate rail 3 is not affected by the size of the sliding direction of the holding member 5 when stored due to the insertion hole 50. The sliding distance does not decrease.
[0021]
【The invention's effect】
According to the first aspect of the present invention, the storage holding member is connected between the upper and lower closing portions protruding from the fixed rail toward the moving rail and the upper and lower storage holding portions. Due to the elastic deformation part, there is no gap between the fixed side rail and the upper and lower storage holding parts, so that the hanging cord enters between the fixed side rail and the moving side rail, gets entangled with the storage holding part, There is no alienation of storage.
[0022]
According to the second aspect of the present invention, in addition to the above-described effect, the upper and lower fitting mounting portions that are fitted to the fixed-side rail, and the elastic mounting substrate that is connected between the upper and lower fitting mounting portions are provided. Therefore, it is easy to attach the holding member to the fixed side rail during storage. In addition, a guide curve part is formed at the moving side front end of the holding part during storage by processing the corner part on the moving side rail with a large curve, so that the cord hanging further from the fixed side rail and the moving side It does not get in between the rails or get entangled with the holding part when stored, and the storage of the mounting shelf is not excluded.
