Description

【０００１】
【発明の属する技術分野】
本発明は、キャビネット等のオフィス用家具や家庭用家具等の引出体の出し入れを行う際の摩擦低減用に用いるガイドレールに関し、所謂、複式ガイドレールに関する。本願の引出体とは、引き出される物一般を表現しており、抽斗や引き出されるテーブル等が含まれる。
【０００２】
【従来の技術】
複式ガイドレールを使用したキャビネット等において、抽斗を引き出す場合に、常にまず中間レール部材が引き出され、次ぎに抽斗側レール部材が引き出され、収納させる場合には、抽斗側レール部材が収納され、次ぎに中間レール部材が収納されるというように、順序が定まっていると、製品に対する信頼性や安心感が高まるものである。
また、抽斗を引き出す場合に、中間レール部材が引き出される前に、既に該中間レール部材に対して抽斗側レール部材が引き出されていると、後から中間レール部材が引き出される際に、抽斗等の荷重が抽斗側レール部材がオーバーハングしている長さに応じたモーメント負荷として、中間レール部材と収納体側レール部材との間に介在するボール等の転動体に対して作用する。このため、転動体に対する動負荷が大きくなり、耐久性に問題が生じる。収納させる場合も同様である。こうした観点から、下記特許文献１には、引き出す場合には、まず、抽斗側レール部材（インナーレール）と共に中間レール部材を引き出し、それから、抽斗側レール部材を引き出し、収納の際は、まず、中間レール部材に対して抽斗側レール部材を収納させ、その後から、抽斗側レール部材と共に中間レール部材を収納させるように規定した構造が開示されている。
【特許文献１】
特公平８−１２１３号公報
【０００３】
【発明が解決しようとする課題】
上記特許文献１では、弾性力の大小、即ち、摩擦力の大小によってレール部材のスライド順序を規定している。従って、その規制力の調節は必ずしも簡便ではなく、より簡便で、確実な規制手法が好ましい。
依って本発明は、簡便かつ確実な構造で、レール部材のスライド順序を規定できる複式ガイドレールの提供を目的とする。
【０００４】
【課題を解決するための手段】
上記目的に鑑みて本発明の請求項１では、キャビネット等の家具の引出体と収納体との間に設けられ、収納体側に装着された収納体側レール部材と、該レール部材に対して相対移動する中間レール部材と、該中間レール部材に対して相対移動すると共に引出体側に装着された引出体側レール部材とを有する複式ガイドレールであって、横断面における中間レール部材の一端側に引出体側レール部材が配設されると共に、他端側に収納体側レール部材が配設され、中間レール部材に取り付けられて枢軸回りに回動可能な規制連結部材を有し、該規制連結部材の収納体側レール部材側の部位に凸部を有しており、引出体側レール部材と中間レール部材がほぼ完全に引き出された状態から、中間レール部材を収納体側レール部材に対して押し込み移動させようとする場合、前記凸部は、該凸部の後側側面に収納体側レール部材前端部が干渉しつつ収納体側レール部材に乗り上がることができる形状であるが、引出体側レール部材によって乗り上がりが規制されており、引出体側レール部材は、該引出体側レール部材が中間レール部材に対してほぼ完全に収納された状態において、前記規制連結部材を少なくとも部分的に受け入れて退避させることのできる凹所を有しており、規制連結部材が該凹所に退避すると前記乗り上がり規制が解除され、中間レール部材は引出体側レール部材と共に収納方向に移動できる他、引き出し時にも共に引き出され、中間レール部材がほぼ完全に引き出された位置では規制連結部材が凹所から出られることを特徴とする複式ガイドレールを提供する。
【０００５】
引出体側レール部材と中間レール部材がほぼ完全に引き出された状態から、中間レール部材を収納体側レール部材に対して押し込み移動させようとする場合、上記凸部は、該凸部の後側側面に収納体側レール部材前端部が干渉しつつ収納体側レール部材に乗り上がることができる形状であるが、引出体側レール部材によって乗り上がりが規制されているため、引出体を収納させようとした場合、中間レール部材は収納移動が規制されており、中間レール部材に対して引出体側レール部材（と引出体）のみが収納移動する。そして、引出体側レール部材が中間レール部材に対してほぼ完全に収納された位置まで来ると、引出体側レール部材の凹所に規制連結部材を受け入れて退避させることができるので、中間レール部材にも伝達されている引出体を押し込む力によって、規制連結部材を押し上げて凹所に退避させることができる。規制連結部材が凹所に退避すると前記乗り上がり規制が解除されて中間レール部材は引出体側レール部材と共に収納方向に移動できる。
引き出す場合も、凹所に入った規制連結部材の作用で中間レール部材は引出体側レール部材と共に引き出される。そして、中間レール部材がほぼ完全に引き出された位置に来れば規制連結部材は凹所から出られるため、引出体側レール部材は中間レール部材との連結を解除できて更に引き出すことができる。
従って、簡便な構造でレール部材が確実に順序良くスライドすることになる。
【０００６】
【発明の実施の形態】
以下、本発明を添付図面に示す実施形態例に基づき、更に詳細に説明する。
図１は本発明に係る複式ガイドレールの側面図であり、幾分引き出した状態の図である。図２はその要部拡大図、図４は図１の矢視線Ｄ−Ｄによる拡大横断面図である。分かり易くするために、図１と図２では一部破線にすべきところを実線表示している。この形態例では、引出体は抽斗であり、図４に横断面を示すように、抽斗側レール部材１４の横断面形状は、４つの平面状壁部で矩形状に囲まれ、その一部に開口部１４Ｋを有している。収納体側レール部材１０の横断面Ｌ字形部材１０Ｂに固定されたレール部材１０Ａも、抽斗側レール部材１４と同様な矩形状横断面を成しており、その一部に開口部１０Ｋを有している。この例では、抽斗側レール部材１４と収納体側レール部材１０のレール部材１０Ａとは上下方向配置関係に配設されており、前者部材の下面１４Ｓと、後者部材の上面１０Ｕとが対面している。この両部材１４，１０Ａとが左右方向に配設されていてもよい。
【０００７】
一方、中間レール部材１２は、横断面における一端部１２Ａ（図４では上側部）が卍形に折り曲げられた折曲壁部に形成されており、他端部１２Ｂ側も同様である。各端部１２Ａ，１２Ｂを、抽斗側レール部材と収納体側レール部材の各開口部から矩形状壁部の内部に挿入している。この形態例では、極めて滑らかに互いにスライド可能にするため、各レール部材を互いに離隔させ、収納体側レール部材と中間レール部材の端部１２Ｂとの間にローラーを装着したユニット体Ｕ１を介在させている。また、抽斗側レール部材と中間レール部材の端部１２Ａとの間にローラーを装着したユニット体Ｕ２を介在させている。図４では、これらユニット体が切断面から離れているため図示を省略している。
【０００８】
中間レール部材１２の所定位置には、前記２つの端部１２Ａ，１２Ｂを連結する横断面中央部の壁部（前記下面１４Ｓと上面１０Ｕとの間）にアーム状の規制連結部材２０が取り付けられている。この規制連結部材は、この壁部を貫通した枢軸２０Ｊ回りに回動自在である。一方、抽斗側レール部材の所定位置には、規制連結部材の前端部の抽斗側レール部材側の凸部２０Ｐが退避できる凹所としての切欠部１４Ｈが設けられている。単なる孔部でもよい。
【０００９】
規制連結部材２０の前記凸部２０Ｐの反対側（収納体側レール部材の側）にも凸部２０Ｔが形成されている。この凸部の後側側面２０ＴＳはなだらかな傾斜状に形成されている。中間レール部材１２が最も引き出された状態（図３）においては、収納体側レール部材１０の前端１０Ｅの直ぐ前に規制連結部材２０の凸部２０Ｔが下がっている。従って、中間レール部材１２を収納する方向に移動させようとすると、規制連結部材凸部の後側側面２０ＴＳが前記前端１０Ｅと干渉する。
【００１０】
更には、抽斗側レール部材１４を中間レール部材１２に対して最も引き出した状態を図３に示しており、この状態においても、抽斗側レール部材下面１４Ｓの後端領域が規制連結部材の一部（この例では凸部２０Ｐ）と対面している。しかも、その対面離隔距離は、図３の規制連結部材２０の凸部２０Ｔの頂部（下端）と、収納体側レール部材１０の上面（抽斗収納状態において前記下面１４Ｓと対面関係となる収納体側レール部材の面）１０Ｕとの高さの差よりも小さい。従って、抽斗を収納させる場合に、その押し込み力が中間レール部材１２にも伝達されるが、規制連結部材（の凸部２０Ｐ）の上方への回動が抽斗側レール部材下面１４Ｓに規制されつつ、規制連結部材の前記後側側面２０ＴＳと収納体側レール部材１０の前端とが干渉し、中間レール部材の移動が規制される。
【００１１】
中間レール部材１２の収納方向への移動が規制されている間に、レール部材では抽斗側レール部材１４だけが収納方向に移動し、中間レール部材に対してほぼ完全に収納された位置に来ると、前記切欠部１４Ｈが規制連結部材の凸部２０Ｐと対面するように構成されている。この間の抽斗収納中は、規制連結部材と収納体側レール部材前端１０Ｅとの干渉作用によって、規制連結部材（の凸部２０Ｔ）は常に収納体側レール部材の上面１０Ｕの高さを越える方向（この例では上方）に回動する作用を受けている。従って、凸部２０Ｐが抽斗側レール部材の切欠部１４Ｈと対面するようになれば、即、切欠部内に侵入退避する。
【００１２】
これにより規制連結部材は収納体側レール部材の上面１０Ｕに乗り上がることができ、中間レール部材１２は収納体側レール部材に対して収納方向に移動可能となる。また、この際、抽斗側レール部材は適宜な度あたり手段によって（場合によっては規制連結部材の凸部２０Ｐとの係合によって）中間レール部材と共に収納方向に移動する。こうして、抽斗を収納しきることができる。中間レール部材が収納体側レール部材に対して完全に収納される位置の規定は適宜な度あたり手段によって行われる。また、切欠部１４Ｈの前後方向長さ等の大きさが規制連結部材凸部２０Ｐより大きくて、収納操作中に抽斗側レール部材の切欠部の孔壁が凸部２０Ｐに当接しなくても本発明の範囲には影響を与えない。この場合、既述のように抽斗側レール部材が中間レール部材に対して完全に収納しきった状態を規定する適宜な度あたり手段を設けている。
【００１３】
抽斗収納状態の場合、規制連結部材２０の凸部２０Ｐが切欠部１４Ｈに侵入退避しているため、抽斗側レール部材を引き出す場合、抽斗側レール部材の切欠部孔壁が、規制連結部材の侵入部分である凸部２０Ｐの後側側面２０Ｋに当接して中間レール部材と抽斗側レール部材とが連結された状態となる。なお、抽斗側レール部材の切欠部壁面が、規制連結部材の凸部後側側面２０Ｋに当接することにより、規制連結部材が押し出し回動されようとするが、規制連結部材の他の凸部２０Ｔが収納体側レール部材１０の上面１０Ｕに規制されて回動できない。
【００１４】
従って、中間レール部材がほぼ完全に引き出された位置（図３）に来て、規制連結部材の凸部２０Ｔが収納体側レール部材の前端１０Ｅから前側に位置して凸部２０Ｐが切欠部１４Ｈから抜け出るまでは、抽斗側レール部材と中間レール部材とは一緒に引き出される。この位置において，凸部２０Ｐが切欠部１４Ｈから円滑に抜け出るためには、前記凸部後側側面２０Ｋが前方に向かって傾斜していて、抽斗側レール部材を引き出すことにより切欠部１４Ｈの孔壁が当接して規制連結部材を押し出すか、或いは、規制連結部材が枢軸２０Ｊの回りに回動して切欠部１４Ｈから抜け出る方向（図３では反時計回り方向）に常に付勢力を付与するバネ等の付勢手段を設けていてもよい。
【００１５】
適宜な度あたり手段によって中間レール部材の完全引き出し位置を規定しており、この状態から更に抽斗を引き出せば、抽斗と共に、レール部材では抽斗側レール部材１４のみが引き出される。該抽斗側レール部材の完全引き出し位置は、適宜な度あたり手段によって規定されている。
以上のように、収納時に抽斗側レール部材と中間レール部材とが共に収納移動されて収納操作が完了する機構としたので、収納操作の完了間際になって作用する自動引き込み装置を、抽斗側レール部材と中間レール部材の何れに作用するように構成しても有効となる。
【００１６】
以上の説明では、各レール部材を円滑にスライドさせるために、転動体を有するユニット体を設けているが、こうした転がり摩擦を使用する機構の形態は任意であると共に、こうした機構は無くてもよい。
以上は抽斗を例に説明したが、引出体は引き出されるテーブル等であってもよい。
夫々の所で述べた変形形態は、互いに矛盾の無い限り、他の形態においても適用できる。
【００１７】
【発明の効果】
以上の説明から明らかなように本発明によれば、簡便かつ確実な構造で、レール部材のスライド順序を規定できる複式ガイドレールが提供可能となる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a guide rail used for reducing friction when a drawer such as an office furniture or a household furniture such as a cabinet is taken in and out, and relates to a so-called double guide rail. The drawer of the present application represents a general thing to be drawn, and includes a drawer, a table to be drawn, and the like.
[0002]
[Prior art]
In a cabinet or the like using a double guide rail, when drawing out the drawer, the intermediate rail member is always drawn out first, then the drawer side rail member is drawn out and stored, and then the drawer side rail member is stored. If the order is determined, for example, the intermediate rail members are stored, the reliability and security of the product will be increased.
When the drawer is drawn out, if the drawer side rail member has already been drawn out with respect to the intermediate rail member before the intermediate rail member is drawn out, when the intermediate rail member is drawn out later, the drawer or the like is used. The load acts as a moment load according to the length of the overhang of the drawer-side rail member on a rolling element such as a ball interposed between the intermediate rail member and the housing-side rail member. For this reason, the dynamic load on the rolling elements increases, and a problem occurs in durability. The same is true for storage. From this point of view, in the following Patent Document 1, when pulling out, first pull out the intermediate rail member together with the drawer side rail member (inner rail), and then pull out the drawer side rail member. There is disclosed a structure in which the drawer-side rail member is stored in the rail member, and thereafter, the intermediate rail member is stored together with the drawer-side rail member.
[Patent Document 1]
Japanese Patent Publication No. 8-1213
[Problems to be solved by the invention]
In Patent Document 1, the sliding order of the rail members is defined by the magnitude of the elastic force, that is, the magnitude of the frictional force. Therefore, the regulation force is not always simple, and a simpler and more reliable regulation method is preferred.
Therefore, an object of the present invention is to provide a multiple guide rail that can specify the sliding order of the rail members with a simple and reliable structure.
[0004]
[Means for Solving the Problems]
In view of the above object, according to claim 1 of the present invention, a storage body side rail member provided between a drawer body of furniture such as a cabinet and a storage body and mounted on the storage body side, and relatively moved with respect to the rail member. A guide rail having a middle rail member to be moved and a drawer body side rail member mounted on the drawer body side while being relatively moved with respect to the intermediate rail member, wherein the drawer body side rail is provided at one end side of the intermediate rail member in a cross section. A member is provided, and a storage body side rail member is provided on the other end side, and a regulating connection member attached to the intermediate rail member and rotatable around a pivot is provided. It has a convex portion on the member side, and pushes the intermediate rail member from the state where the drawer body side rail member and the intermediate rail member are almost completely pulled out to the storage body side rail member and transfers them. When the protruding portion is to be formed, the protruding portion has a shape capable of climbing on the housing body side rail member while the front end portion of the housing body side rail member interferes with the rear side surface of the protruding portion. The uplift is restricted, and the drawer body-side rail member can at least partially receive and retract the restricting connection member in a state where the drawer body-side rail member is almost completely housed with respect to the intermediate rail member. When the regulating connecting member retracts into the concave, the climbing-up restriction is released, and the intermediate rail member can be moved together with the drawer body-side rail member in the storage direction, and is also pulled out at the time of pulling out. A double guide rail is provided, wherein the restricting connection member comes out of the recess when the rail member is almost completely extended.
[0005]
When the intermediate rail member is to be pushed and moved with respect to the storage body side rail member from a state in which the drawer body side rail member and the intermediate rail member are almost completely pulled out, the convex portion is provided on the rear side surface of the convex portion. Although the shape is such that the front end of the storage body side rail member can ride on the storage body side rail member while interfering, the climbing up is regulated by the drawer body side rail member, so if you try to store the drawer, The storage movement of the rail member is restricted, and only the drawer body side rail member (and the drawer body) is stored and moved with respect to the intermediate rail member. Then, when the drawer-side rail member reaches the position where it is almost completely stored with respect to the intermediate rail member, the restricting connecting member can be received and retracted in the recess of the drawer-side rail member. The restricting connecting member can be pushed up and retracted into the recess by the transmitted force of pushing the drawer. When the restriction connecting member is retracted into the recess, the climbing restriction is released, and the intermediate rail member can move in the storage direction together with the drawer-side rail member.
Also in the case of pulling out, the intermediate rail member is pulled out together with the drawer-side rail member by the action of the restricting connecting member that has entered the recess. Then, when the intermediate rail member comes to a position where it is almost completely pulled out, the restricting connecting member comes out of the recess, so that the drawer-body-side rail member can be disconnected from the intermediate rail member and further pulled out.
Therefore, the rail members can be reliably slid in order with a simple structure.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in more detail based on embodiments shown in the accompanying drawings.
FIG. 1 is a side view of a compound guide rail according to the present invention, in a state where it is somewhat pulled out. 2 is an enlarged view of a main part thereof, and FIG. 4 is an enlarged cross-sectional view taken along the line DD in FIG. For the sake of simplicity, in FIG. 1 and FIG. 2, parts that should be partially broken lines are indicated by solid lines. In this embodiment, the drawer is a drawer, and as shown in a cross section in FIG. 4, the cross-sectional shape of the drawer-side rail member 14 is rectangularly surrounded by four planar walls, and a part thereof It has an opening 14K. The rail member 10A fixed to the transverse section L-shaped member 10B of the storage body side rail member 10 also has a rectangular cross section similar to the drawer side rail member 14, and has an opening 10K in a part thereof. I have. In this example, the drawer side rail member 14 and the rail member 10A of the storage body side rail member 10 are disposed in a vertical arrangement relationship, and the lower surface 14S of the former member and the upper surface 10U of the latter member face each other. . The two members 14, 10A may be arranged in the left-right direction.
[0007]
On the other hand, the intermediate rail member 12 is formed with a bent wall portion in which one end portion 12A (upper portion in FIG. 4) in a cross section is bent in a swastika shape, and the other end portion 12B side is the same. The ends 12A and 12B are inserted into the rectangular wall from the openings of the drawer-side rail member and the storage body-side rail member. In this embodiment, the rail members are separated from each other so as to be able to slide extremely smoothly with each other, and a unit body U1 equipped with a roller is interposed between the storage body side rail member and the end 12B of the intermediate rail member. I have. Further, a unit body U2 with a roller is interposed between the drawer side rail member and the end 12A of the intermediate rail member. In FIG. 4, these units are not shown because they are separated from the cut surface.
[0008]
At a predetermined position of the intermediate rail member 12, an arm-shaped regulating connecting member 20 is attached to a wall portion (between the lower surface 14S and the upper surface 10U) at the center of the cross section connecting the two end portions 12A and 12B. ing. The restricting connecting member is rotatable around a pivot 20J penetrating the wall. On the other hand, at a predetermined position of the drawer-side rail member, a cutout portion 14H is provided as a recess in which the protrusion 20P on the drawer-side rail member side at the front end of the restricting connection member can be retracted. It may be a simple hole.
[0009]
A convex portion 20T is also formed on the opposite side of the restricting connecting member 20 from the convex portion 20P (on the side of the storage body side rail member). The rear side surface 20TS of the projection is formed in a gentle slope. In a state where the intermediate rail member 12 is pulled out most (FIG. 3), the protrusion 20 </ b> T of the regulation connecting member 20 is lowered immediately before the front end 10 </ b> E of the storage body side rail member 10. Therefore, when the intermediate rail member 12 is to be moved in the housing direction, the rear side surface 20TS of the restricting connecting member convex portion interferes with the front end 10E.
[0010]
Further, FIG. 3 shows a state in which the drawer-side rail member 14 is pulled out most from the intermediate rail member 12, and even in this state, the rear end area of the lower surface 14S of the drawer-side rail member is a part of the regulation connecting member. (In this example, the projection 20P). In addition, the facing separation distance is determined by the top (lower end) of the convex portion 20T of the restricting connecting member 20 in FIG. 3 and the upper surface of the storage body side rail member 10 (the storage body side rail member facing the lower surface 14S in the drawer storage state). Surface) is smaller than the height difference from 10U. Therefore, when the drawer is housed, the pushing force is also transmitted to the intermediate rail member 12, but the upward rotation of the restricting connecting member (the convex portion 20 </ b> P) is restricted by the drawer side rail member lower surface 14 </ b> S. Then, the rear side surface 20TS of the restricting connecting member interferes with the front end of the housing-side rail member 10, and the movement of the intermediate rail member is restricted.
[0011]
While the movement of the intermediate rail member 12 in the storage direction is restricted, only the drawer-side rail member 14 of the rail member moves in the storage direction and comes to a position almost completely stored with respect to the intermediate rail member. The notch 14H is configured to face the convex portion 20P of the restricting connection member. During the drawer storage during this time, due to the interference action between the restricting connecting member and the front end 10E of the storing body side rail member, the restricting connecting member (the convex portion 20T) always exceeds the height of the upper surface 10U of the storing body side rail member (this example). (Upward). Therefore, as soon as the convex portion 20P faces the cutout portion 14H of the drawer side rail member, the convex portion 20P enters and retreats into the cutout portion.
[0012]
As a result, the regulating connection member can ride on the upper surface 10U of the storage body side rail member, and the intermediate rail member 12 can move in the storage direction with respect to the storage body side rail member. At this time, the drawer-side rail member is moved in the storage direction together with the intermediate rail member by an appropriate stop means (in some cases, by engagement with the convex portion 20P of the regulating connection member). Thus, the drawer can be completely stored. The position where the intermediate rail member is completely stored with respect to the storage body side rail member is determined by an appropriate stop means. The size of the notch 14H, such as the length in the front-rear direction, is larger than the restricting connecting member convex portion 20P, and even if the hole wall of the notch of the drawer side rail member does not contact the convex portion 20P during the storing operation. It does not affect the scope of the invention. In this case, as described above, an appropriate stop means is provided for defining a state in which the drawer side rail member is completely housed in the intermediate rail member.
[0013]
In the drawer retracted state, the protrusion 20P of the restricting connecting member 20 has entered and retracted into the cutout 14H. Therefore, when the drawer side rail member is pulled out, the cutout hole wall of the drawer side rail member is intruded by the restricting connecting member. The intermediate rail member and the drawer-side rail member are brought into contact with each other by contacting the rear side surface 20K of the convex portion 20P which is the portion. When the cutout wall surface of the drawer-side rail member comes into contact with the rear side surface 20K of the convex portion of the restricting connecting member, the restricting connecting member is about to be pushed and rotated. Is restricted by the upper surface 10U of the housing-side rail member 10 and cannot rotate.
[0014]
Accordingly, the intermediate rail member comes to a position where it is almost completely pulled out (FIG. 3), the convex portion 20T of the restricting connecting member is located on the front side from the front end 10E of the storage body side rail member, and the convex portion 20P is formed from the notch 14H. Until it comes out, the drawer side rail member and the intermediate rail member are pulled out together. In this position, in order for the convex portion 20P to come out of the notch portion 14H smoothly, the rear side surface 20K of the convex portion is inclined forward and the hole wall of the notch portion 14H is pulled out by pulling out the drawer side rail member. Abuts on and pushes out the restricting connecting member, or a spring or the like that always applies a biasing force in a direction (counterclockwise in FIG. 3) in which the restricting connecting member rotates around the pivot 20J and comes out of the notch 14H. May be provided.
[0015]
The full pull-out position of the intermediate rail member is defined by an appropriate stop means. If the drawer is further pulled out from this state, only the drawer-side rail member 14 is pulled out of the rail member together with the drawer. The position where the drawer-side rail member is completely pulled out is defined by an appropriate stop means.
As described above, since the drawer-side rail member and the intermediate rail member are stored and moved together during storage to complete the storage operation, an automatic retraction device that operates just before the completion of the storage operation is used as the drawer-side rail. It is effective to configure so as to act on either the member or the intermediate rail member.
[0016]
In the above description, a unit body having a rolling element is provided in order to smoothly slide each rail member. However, the form of a mechanism using such rolling friction is arbitrary, and such a mechanism may be omitted. .
Although the drawer has been described above as an example, the drawer may be a table or the like from which the drawer is drawn.
The modifications described in each place can be applied to other forms as long as they do not conflict with each other.
[0017]
【The invention's effect】
As is clear from the above description, according to the present invention, it is possible to provide a multiple guide rail that can specify the sliding order of the rail members with a simple and reliable structure.
