An object of the present invention is to provide a slide rail locking device having excellent maintainability.

そこで、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、ラック等の本体に固定される固定側レールと、固定側レールに対し摺動自在に配設された中間レールと、中間レールに対し摺動自在に配設された移動側レールと、移動側レールの前端部の上下折曲縁間の基板に固定された係止部材と、係止部材に対応して、固定側レールの前端部の上下折曲縁間に固定されたロック部材よりなるスライドレールのロック装置であって、ロック装置は、係止部材に設けられる係止突起と、ロック部材に設けられる係合部が係合することによりロック状態が維持されるもので、ロック装置のロック状態を解除する操作部を、固定側レールの前端より前方に突出するように固定側レール側に設けるとともに、操作部を含むロック部材を、移動側レールの上下折曲縁間の基板の上下方向の中心部であってスライドレールの伸長方向に伸びる水平線上に、ロック部材の上下方向の中心部であって伸長方向に伸びる水平線が略重なるように配置し、かつ、操作部の非操作時に中間レールの摺動軌跡上に干渉しない大きさで形成し、係止突起を、スライドレールが伸長した状態の操作部の非操作時に、ロック部材の該水平線のスライドレールの伸長方向の延長線上に配置するものである。 Therefore, in order to solve the above problems, the present invention is configured as the first means: a fixed side rail fixed to the main body of a rack or the like, and an intermediate rail slidably arranged with respect to the fixed side rail. The moving side rail slidably arranged with respect to the intermediate rail, the locking member fixed to the substrate between the upper and lower bent edges of the front end of the moving side rail, and the locking member corresponding to the locking member. A slide rail locking device composed of a locking member fixed between the upper and lower bent edges of the front end of the fixed side rail, and the locking device is a locking projection provided on the locking member and a engagement provided on the locking member. The locked state is maintained by engaging the joints, and the operating unit for releasing the locked state of the locking device is provided on the fixed side rail side so as to protrude forward from the front end of the fixed side rail, and is operated. The lock member including the portion is extended at the vertical center of the lock member on the horizontal line extending in the vertical direction of the slide rail between the vertical bending edges of the moving side rail. The horizontal lines extending in the direction are arranged so as to substantially overlap, and the operation unit is formed in a size that does not interfere with the sliding locus of the intermediate rail when the operation unit is not operated. When not operated, the lock member is arranged on an extension of the slide rail of the horizontal line in the extension direction.

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、前記第１の手段に加え、スライドレールのロック状態において、移動側レールを伸長方向に移動させる付勢手段を設け、該付勢手段の付勢力により、該係止突起と係合部の係合によるロック状態において、常に係止突起を係合部に押圧させるものである。 In order to solve the above problems, where the present invention is configured as the second means, in addition to the first means, an urging means for moving the moving side rail in the extension direction in the locked state of the slide rail is provided . The urging force of the urging means always presses the locking projection against the engaging portion in the locked state due to the engagement between the locking projection and the engaging portion .

本発明の第１の手段として構成したところによると、操作部を含むロック部材が、中間レールの摺動軌跡上に干渉しない大きさで形成されているので、操作部を固定レール側に設けることができる。そのため、スライドレールを伸長させた状態で、操作部が移動側レールの前端より前に突出することがない。したがって、ロック装置の外れや、破損につながることを防止できる。 According to the first means of the present invention, the lock member including the operation portion is formed in a size that does not interfere with the sliding locus of the intermediate rail, so that the operation portion is provided on the fixed rail side. Can be done. Therefore, in the extended state of the slide rail, the operation unit does not protrude in front of the front end of the moving side rail. Therefore, it is possible to prevent the locking device from coming off or being damaged.

本発明の第２の手段として構成したところによると、中間レールあるいは移動レール、すなわち、摺動する側のレールを伸長方向に付勢しているので、操作部を操作してロックを解除すると、付勢力によって摺動する側のレールが伸長し、ロック解除状態が維持される。そのため、一旦ロック解除すれば、操作部を操作せずとも移動側レールを引き出すことができるので、スライドレールの操作性が良い。
また、ロック状態においても、摺動する側のレールを伸長方向に付勢しているので、係止部材の係止突起とロック部材の係止部の係合によるロック状態において、常に係止突起を係止部に押圧させることができるため、ロック状態を確実に維持することが可能である。 According to the second means of the present invention, the intermediate rail or the moving rail, that is, the sliding side rail is urged in the extension direction. The rail on the sliding side is extended by the urging force, and the unlocked state is maintained. Therefore, once the lock is released, the moving side rail can be pulled out without operating the operation unit, so that the operability of the slide rail is good.
Further, even in the locked state, since the rail on the sliding side is urged in the extension direction, the locking protrusion is always locked in the locked state due to the engagement between the locking projection of the locking member and the locking portion of the locking member. Can be pressed against the locking portion, so that the locked state can be reliably maintained.

尚、リベット止めに限らず、取付基部６１の移動側レール２の基板２２側にピン状の突起体を一体的に設けて、固定側レール１の基板１２の貫通孔に差込み固定する方法でもよい。
そして、回転止め部６２は、固定側レール１の基板１２に、上下方向に間隔を空けて設けられた上下一対の突出片で形成されるレール伸長時ストッパー１３の該間隔部にはめ込まれるものであって、固定側レール１に取り付けられたロック部材６が上下方向に回動することを防止している。回転止め部６２によって、前記の取付基部６１の固定をリベット６１３のように一点止めとすることができるので組み立てが容易である。 The mounting base 61 is formed with a fixing hole 612 that penetrates from the front surface side to the back surface side (the surface of the moving side rail 2 on the substrate 22 side), and also penetrates the substrate 12 of the fixed side rail 1 corresponding to the fixing hole 612. A hole is provided. The lock member 6 is attached to the fixed side rail 1 by a synthetic resin rivet 613 using the through hole and the fixed hole 612.
The method is not limited to riveting, and a method of integrally providing a pin-shaped protrusion on the board 22 side of the moving side rail 2 of the mounting base 61 and inserting and fixing the pin-shaped protrusion into the through hole of the board 12 of the fixed side rail 1 may be used. ..
The rotation stop portion 62 is fitted into the gap portion of the rail extension stopper 13 formed of a pair of upper and lower protruding pieces provided at intervals in the vertical direction on the substrate 12 of the fixed side rail 1. Therefore, the lock member 6 attached to the fixed side rail 1 is prevented from rotating in the vertical direction. Assembling is easy because the rotation stopper 62 allows the mounting base 61 to be fixed at one point like the rivet 613.

弾性誘導部６３は、取付基部６１、操作部６４より上下方向に幅狭く形成されており、操作部６４は、角棒状に前方に突出したもので、先端部の上下面にそれぞれ傾斜面を有し先端が尖った状態の案内部６４ａが形成されている。
そして、操作部６４の弾性誘導部６３寄りに設けられた係合部６５は、インナー中間レール４ａの基板４１ｂ側から固定側レール１の基板１２に向かって凹状に形成されており、凹状部を形成する前側の垂直面が後述する係止部材７と係合する係合面６５ａとされる。
該凹状に形成される係合部６５は、後述する係止部材７の係止突起７５が上下方向に自由に行き来できる大きさに設定されている。 The elastic guide portion 63 is formed to be narrower in the vertical direction than the mounting base portion 61 and the operation portion 64, and the operation portion 64 projects forward in the shape of a square bar and has inclined surfaces on the upper and lower surfaces of the tip portions. A guide portion 64a having a sharp tip is formed.
The engaging portion 65 provided near the elastic guiding portion 63 of the operating portion 64 is formed in a concave shape from the substrate 41b side of the inner intermediate rail 4a toward the substrate 12 of the fixed side rail 1, and the concave portion is formed. The vertical surface on the front side to be formed is an engaging surface 65a that engages with the locking member 7 described later.
The concavely formed engaging portion 65 is set to a size that allows the locking projection 75 of the locking member 7, which will be described later, to freely move back and forth in the vertical direction.

このように形成されているロック部材６は、操作部６４が、固定側レール１の前端より前方に突出した状態で固定側レール１に取り付けられる。
また、ロック部材６は、インナー中間レール４ａの上下折曲縁４２ａ、４２ａ間に納まる高さに設定されるとともに、固定側レール１の基板１２とインナー中間レール４ａの基板４１ｂ間に納まる厚さに形成されているので、インナー中間レール４ａの摺動時にインナー中間レール４ａに接触することがなく、インナー中間レール４ａの摺動に支障がでない。
したがって、操作部６４の非操作時には、ロック部材６は、中間レール４のインナー中間レール４ａの摺動軌跡上に干渉しない。 The lock member 6 formed in this way is attached to the fixed side rail 1 in a state where the operating portion 64 projects forward from the front end of the fixed side rail 1.
Further, the lock member 6 is set to a height that fits between the upper and lower bent edges 42a and 42a of the inner intermediate rail 4a, and has a thickness that fits between the substrate 12 of the fixed side rail 1 and the substrate 41b of the inner intermediate rail 4a. Since it is formed on the inner intermediate rail 4a, it does not come into contact with the inner intermediate rail 4a when the inner intermediate rail 4a is slid, and the sliding of the inner intermediate rail 4a is not hindered.
Therefore, when the operation unit 64 is not operated, the lock member 6 does not interfere with the sliding locus of the inner intermediate rail 4a of the intermediate rail 4.

係止部材７は、移動側レール２の基板２２と、上下折曲縁２１、２１の内面に形成される膨出凸部２ａ、２ａとの間で形成される空間２３に嵌入される固定基部７２と、固定基部７２の後方に突出する固定部７３と、固定基部７２の前面に形成されるフランジ部７４と、固定基部７２の表面より固定側レール１側に突出する係止突起７５が合成樹脂材にて一体に形成されている。 The locking member 7 is a fixed base that is fitted into a space 23 formed between the substrate 22 of the moving side rail 2 and the bulging protrusions 2a and 2a formed on the inner surfaces of the upper and lower bent edges 21 and 21. 72, a fixing portion 73 projecting rearward of the fixing base portion 72, a flange portion 74 formed on the front surface of the fixing base portion 72, and a locking projection 75 projecting from the surface of the fixing base portion 72 toward the fixed side rail 1 are combined. It is integrally formed of a resin material.

固定基部７２は、前記空間２３に嵌入される嵌入部分と、該嵌入部分から固定側レール１方向に固定側レール１に設けられている操作部６４の移動側レール２側面近傍までの部分が一体的とされる方形に形成され、嵌入部分の上下面には移動側レール２の上下折曲縁２１、２１の内面の膨出凸部２ａ、２ａに沿う形状とされる上下勘合溝７２１、７２１が形成されている。 In the fixed base portion 72, a fitting portion to be fitted into the space 23 and a portion from the fitting portion to the vicinity of the side surface of the moving side rail 2 of the operation portion 64 provided on the fixed side rail 1 in the fixed side rail 1 direction are integrated. Upper and lower fitting grooves 721 and 721, which are formed in a square shape to be targeted and have a shape along the bulging convex portions 2a and 2a on the inner surface of the upper and lower curved edges 21 and 21 of the moving side rail 2 on the upper and lower surfaces of the fitting portion. Is formed.

固定部７３は、前記空間２３に納まる大きさで表面側から裏面側（移動側レール２の基板２２側の面）にかけて貫通する固定孔７３１が形成されている。 The fixing portion 73 is formed with a fixing hole 731 having a size that fits in the space 23 and penetrates from the front surface side to the back surface side (the surface of the moving side rail 2 on the substrate 22 side).

フランジ部７４は、移動側レール２の前端面部を塞ぐように板状に形成され、移動側レール２の上下高さと略同じ高さに設定されている。従って、フランジ部７４は、固定基部７２に対して、移動側レール２の上下折曲縁２１、２１の板厚分を付加した高さとなる。 The flange portion 74 is formed in a plate shape so as to close the front end surface portion of the moving side rail 2, and is set to substantially the same height as the vertical height of the moving side rail 2. Therefore, the flange portion 74 has a height obtained by adding the plate thicknesses of the upper and lower bent edges 21 and 21 of the moving side rail 2 to the fixed base portion 72.

係止突起７５は、前後方向に細長な突起であって、固定基部７２の固定側レール１側の表面より、前述の操作部６４に設けられた係合部６５の凹状部の底面に近傍する程度の突起高さに設定されている。そして、係止突起７５の後端側の上面と下面に、前記操作部６４に形成された案内部６４ａに対応して、前方に向かって上面は上方に下面は下方にそれぞれ傾斜する案内傾斜部７５ａ、７５ａと、操作部６４に形成された係合部６５の係合面６５ａに対応して前端部に形成された当接係止部７５２が形成されている。 The locking projection 75 is an elongated protrusion in the front-rear direction, and is closer to the bottom surface of the concave portion of the engaging portion 65 provided in the operation portion 64 described above from the surface of the fixing base 72 on the fixed side rail 1 side. It is set to a protrusion height of about. Then, on the upper surface and the lower surface of the locking projection 75 on the rear end side, the upper surface is inclined upward and the lower surface is inclined downward corresponding to the guide portion 64a formed in the operation portion 64, respectively. A contact locking portion 752 formed at the front end portion is formed corresponding to the engaging surface 65a of the engaging portion 65 formed on the operating portion 64 and the 75a and 75a.

このように構成された係止部材７は、移動側レール２に取り付けられるが、その取り付け方法について説明する。 The locking member 7 configured in this way is attached to the moving side rail 2, and the attachment method thereof will be described.

移動側レール２の前端面側から、空間２３に係止部材７の固定部７３側を差し込むように入れ、固定基部７２の上下勘合溝７２１、７２１が移動側レール２の膨出凸部２ａ、２ａに沿うように押し込みながら、フランジ部７４の後面が、移動側レール２の前端面に当接するまで差し込む。
そして、固定孔７３１を利用して移動側レール２の基板２２に合成樹脂製リベット７３２によって移動側レール２に取り付けられる。
尚、リベット止めに限らず、固定部７３の移動側レール２の基板２２側にピン状の突起体を一体的に設けて、移動側レール２の前端面側から係止部材７を差し込む際、合成樹脂材で形成される係止部材７の弾性力を利用し、該突起体が弾性変形しながら基板２２上を移動し、所定の位置で、弾性変形後の復元力で該突起体を基板２２の固定孔と勘合させて、移動側レール２に対して、係止部材７を固定させる方法でもよい。
あるいは、基板２２に固定部７３側へ突起する突起部を設け、該突起部に対応して固定部７３に凹部を設け、移動側レール２の前端面側から係止部材７を差し込む際、合成樹脂材で形成される係止部材７の弾性力を利用し、該突起部を乗り越えながら差し込み、弾性変形後の復元力で突起部と凹部を勘合させて、移動側レール２に対して、係止部材７を固定させる方法でもよい。 From the front end surface side of the moving side rail 2, the fixing portion 73 side of the locking member 7 is inserted into the space 23 so that the upper and lower fitting grooves 721 and 721 of the fixing base 72 are inserted into the bulging convex portion 2a of the moving side rail 2. While pushing along 2a, the flange portion 74 is inserted until the rear surface of the flange portion 74 abuts on the front end surface of the moving side rail 2.
Then, the fixing hole 731 is used to attach the substrate 22 of the moving side rail 2 to the moving side rail 2 by a synthetic resin rivet 732.
Not limited to rivet fixing, when a pin-shaped protrusion is integrally provided on the substrate 22 side of the moving side rail 2 of the fixing portion 73 and the locking member 7 is inserted from the front end surface side of the moving side rail 2. Utilizing the elastic force of the locking member 7 formed of the synthetic resin material, the protrusion moves on the substrate 22 while being elastically deformed, and the protrusion is placed on the substrate by the restoring force after the elastic deformation at a predetermined position. A method of fixing the locking member 7 to the moving side rail 2 by fitting it with the fixing hole of 22 may also be used.
Alternatively, the substrate 22 is provided with a protrusion protruding toward the fixing portion 73, a recess is provided in the fixing portion 73 corresponding to the protrusion, and the locking member 7 is inserted from the front end surface side of the moving side rail 2. Using the elastic force of the locking member 7 formed of the resin material, it is inserted while overcoming the protrusion, and the protrusion and the recess are fitted by the restoring force after elastic deformation, and is engaged with the moving side rail 2. A method of fixing the stop member 7 may also be used.

付勢装置１０は、ケース体１０１と、ケース体１０１の内部に収容される付勢バネ１０２と、ケース体１０１内部を前後方向に摺動する摺動体１０３で構成されるものである。 The urging device 10 is composed of a case body 101, an urging spring 102 housed inside the case body 101, and a sliding body 103 that slides inside the case body 101 in the front-rear direction.

ケース体１０１は、固定側レール１の上下折曲縁１１、１１間に納まる高さの箱体で前面側が開放されており内部空間１０１ａが開放前面から露呈し、内部空間１０１ａを摺動体１０３が前後方向に移動できるよう施され、ケース体１０１の後部側に、基板１２側から移動側レール２の方向に向かって縦細長状の固定貫通孔１０１ｂが設けられており、上下面にはそれぞれ、固定側レール１の上下折曲縁１１、１１内面に沿う形状とされる帯状膨出部１０１ｃ、１０１ｃが形成され、これらが一体に合成樹脂製で成型されている。 The case body 101 is a box body having a height that fits between the upper and lower bent edges 11 and 11 of the fixed side rail 1, and the front side is open, the internal space 101a is exposed from the open front surface, and the sliding body 103 exposes the internal space 101a. The case body 101 is provided so as to be movable in the front-rear direction, and a vertically elongated fixed through hole 101b is provided on the rear side of the case body 101 from the substrate 12 side toward the moving side rail 2, respectively. Band-shaped bulging portions 101c and 101c having a shape along the inner surfaces of the upper and lower bent edges 11 and 11 of the fixed side rail 1 are formed, and these are integrally molded of synthetic resin.

付勢バネ１０２は圧縮コイルばねで、ケース体１０１の内部空間１０１ａに付勢力方向が前方向になるように水平に配設されている。
摺動体１０３は、合成樹脂製でケース体１０１の内部空間１０１ａに納まる形態の立法体を成している。また摺動体１０３の後面から前面側に向かって付勢バネ１０２の前側の一部が収容されるキリ孔１０３ａが設けられ、付勢バネ１０２が内部空間１０１ａ内で無用に動かないように施されている。 The urging spring 102 is a compression coil spring, and is horizontally arranged in the internal space 101a of the case body 101 so that the urging force direction is the forward direction.
The sliding body 103 is made of synthetic resin and forms a legislative body that fits in the internal space 101a of the case body 101. Further, a drill hole 103a is provided in which a part of the front side of the urging spring 102 is housed from the rear surface of the sliding body 103 toward the front surface side, and the urging spring 102 is provided so as not to move unnecessarily in the internal space 101a. ing.

そして、付勢装置１０は、次のように、固定側レール１に組み付けられる。
まず、摺動体１０３のキリ孔１０３ａに付勢バネ１０２の前部を挿入し、付勢バネ１０２が装着された摺動体１０３をケース体１０１の内部空間１０１ａにケース体１０１の前面から挿入する。この状態で、摺動体１０３の後部側約三分の一は、内部空間１０１ａに入っており、この時、付勢バネ１０３は完全に伸びた状態となるように付勢バネ１０３の長さ設定されている。したがって、摺動体１０３は、後部側三分の一が内部空間１０１ａに入った状態からでは付勢バネ１０３の付勢力は働かず、摺動体１０３は前方には飛び出さない。このようにして付勢装置１０は組み立てられる。
また、この状態から摺動体１０３の前面を後方に向かって押すと、付勢バネ１０３を圧縮しながら、摺動体１０３はケース体１０１の内部空間１０１ａ内を後方に摺動し、そして、付勢バネ１０３が完全に圧縮した状態の位置で移動が停止する。この状態で摺動体１０３の約五分の四が内部空間１０１ａに入っており、摺動体１０３の後方への押圧を止めると、付勢バネ１０３の付勢力により、摺動体１０３は前方に移動し、摺動体１０３の後部側約三分の一が内部空間１０１ａに入った元の状態にもどる。 Then, the urging device 10 is assembled to the fixed side rail 1 as follows.
First, the front portion of the urging spring 102 is inserted into the drilled hole 103a of the sliding body 103, and the sliding body 103 to which the urging spring 102 is mounted is inserted into the internal space 101a of the case body 101 from the front surface of the case body 101. In this state, about one-third of the rear side of the sliding body 103 is in the internal space 101a, and at this time, the length of the urging spring 103 is set so that the urging spring 103 is in a completely extended state. Has been done. Therefore, in the sliding body 103, the urging force of the urging spring 103 does not work from the state where the rear third is in the internal space 101a, and the sliding body 103 does not protrude forward. The urging device 10 is assembled in this way.
Further, when the front surface of the sliding body 103 is pushed backward from this state, the sliding body 103 slides backward in the internal space 101a of the case body 101 while compressing the urging spring 103, and the urging spring 103 is urged. The movement stops at the position where the spring 103 is completely compressed. In this state, about four-fifths of the sliding body 103 is in the internal space 101a, and when the backward pressing of the sliding body 103 is stopped, the sliding body 103 moves forward due to the urging force of the urging spring 103. , About one-third of the rear side of the sliding body 103 returns to the original state in which it has entered the internal space 101a.

組み立てられた付勢装置１０を、固定側レール１の断面略Ｃ字形を成した開口側から、ケース体１０１の固定貫通孔１０１ｂに、固定側レール１の後端折り曲げ縁１４が差し込まれるように、押圧しながら装着する。この時、ケース体１０１の帯状膨出部１０１ｃ、１０１ｃは、弾性変形しながら固定側レール１の上下折曲縁１１、１１内面に挿入され、挿入後に帯状膨出部１０１ｃ、１０１ｃは、弾性により元の形状に戻り固定側レール１の上下折曲縁１１、１１内面に沿う状態となる。
したがって、付勢装置１０は、固定貫通孔１０１ｂに後端折り曲げ縁１４が差し込まれているため、前後方向に不動で、帯状膨出部１０１ｃ、１０１ｃが上下折曲縁１１、１１内面に沿っているため、固定側レール１から簡単に外れることがない。このようにして付勢装置１０は、固定側レール１に組み付けられる。 The assembled urging device 10 is inserted into the fixed through hole 101b of the case body 101 from the opening side having a substantially C-shaped cross section of the fixed side rail 1 so that the rear end bending edge 14 of the fixed side rail 1 is inserted. , Wear while pressing. At this time, the band-shaped bulging portions 101c and 101c of the case body 101 are inserted into the upper and lower bent edges 11 and 11 of the fixed side rail 1 while being elastically deformed, and after the insertion, the strip-shaped bulging portions 101c and 101c are elastically deformed. It returns to the original shape and is in a state along the upper and lower bent edges 11 and 11 of the fixed side rail 1.
Therefore, since the rear end bent edge 14 is inserted into the fixed through hole 101b, the urging device 10 is immovable in the front-rear direction, and the band-shaped bulges 101c and 101c are along the inner surfaces of the upper and lower bent edges 11 and 11. Therefore, it does not easily come off from the fixed side rail 1. In this way, the urging device 10 is assembled to the fixed side rail 1.

第１実施例のロック部材６と係止部材７は上記の如く形成され、移動側レール２が最大伸長状態（引出し、棚板等が最も引き出された状態）から移動側レール２を収納していくと、固定側レール１に対して中間レール４が先に収納されたり、或いは、中間レール４に対し移動側レール２が先に収納されたり、さらには、移動側レール２の中間レール４に対する収納と、固定側レール１に対する中間レール４の収納が同時に行われたりする。 The locking member 6 and the locking member 7 of the first embodiment are formed as described above, and the moving side rail 2 is housed from the maximum extended state (the state in which the drawer, the shelf board, etc. are most pulled out). Then, the intermediate rail 4 is stored first with respect to the fixed side rail 1, or the moving side rail 2 is stored first with respect to the intermediate rail 4, and further, with respect to the intermediate rail 4 of the moving side rail 2. Storage and storage of the intermediate rail 4 with respect to the fixed side rail 1 are performed at the same time.

しかしながら、ロック部材６が、固定側レール１の前方に設けられ、係止部材７が移動側レール２の前方に設けられているので、移動側レール２と中間レール４の固定側レール１に対する収納順位にかかわらず、最終的には、係止部材７の係止突起７５に形成された案内傾斜部７５ａの収納方向先端側の上面と、操作部６４に形成された案内部６４ａが接触する（図７に示す状態。）。 However, since the lock member 6 is provided in front of the fixed side rail 1 and the locking member 7 is provided in front of the moving side rail 2, the moving side rail 2 and the intermediate rail 4 are stored in the fixed side rail 1. Regardless of the order, finally, the upper surface of the guide inclined portion 75a formed on the locking projection 75 of the locking member 7 on the tip side in the storage direction comes into contact with the guide portion 64a formed on the operating portion 64 ( The state shown in FIG. 7).

さらに、移動側レール２を収納させると、案内傾斜部７５ａの上面と案内部６４ａの下面が接触し、案内傾斜部７５ａの上面と案内部６４ａの下面の傾斜によって、操作部６４は、上方に押し上げられる（図８に示す状態。）。
この時、ロック部材６の弾性誘導部６３が取付基部６１、操作部６４より上下方向に幅狭く形成されているから、取付基部６１、操作部６４より剛性が低いので、操作部６４は、上方に押し上げられることにより弾性誘導部６３が弾性変形し始める。
そして、弾性誘導部６３の弾性変形の復元力により、移動側レール２を収納移動に合わせて、係止突起７５の上面に操作部６４の下面が押し付けられながら移動していく（図９に示す状態。）。 Further, when the moving side rail 2 is housed, the upper surface of the guide inclined portion 75a and the lower surface of the guide portion 64a come into contact with each other, and the operation unit 64 moves upward due to the inclination of the upper surface of the guide inclined portion 75a and the lower surface of the guide portion 64a. Pushed up (state shown in FIG. 8).
At this time, since the elastic guide portion 63 of the lock member 6 is formed to be narrower in the vertical direction than the mounting base portion 61 and the operating portion 64, the rigidity is lower than that of the mounting base portion 61 and the operating portion 64, so that the operating portion 64 is moved upward. The elastic guide portion 63 begins to be elastically deformed by being pushed up.
Then, due to the restoring force of the elastic deformation of the elastic guiding portion 63, the moving side rail 2 moves while being pressed against the upper surface of the locking projection 75 by the lower surface of the operating portion 64 (shown in FIG. 9). situation.).

該ロック部材６と係止部材７の動きの過程と前後して、移動側レール２の移動側レール後端ストッパー２２０が、アウター中間レール後端ストッパー４４ｂに当接して、中間レール４は、移動側レール２に押されるように移動側レール２と合わせて収納されていく。
そして、中間レール４が、移動側レール２と合わせて収納されていくと、インナー中間レール後端ストッパー４４ａ後面が、付勢装置１０の摺動体１０３の前面に当接する。 Before and after the process of movement of the locking member 6 and the locking member 7, the moving side rail rear end stopper 220 of the moving side rail 2 comes into contact with the outer intermediate rail rear end stopper 44b, and the intermediate rail 4 moves. It is stored together with the moving side rail 2 so as to be pushed by the side rail 2.
Then, when the intermediate rail 4 is housed together with the moving side rail 2, the rear surface of the inner intermediate rail rear end stopper 44a comes into contact with the front surface of the sliding body 103 of the urging device 10.

さらに、移動側レール２を収納させると、摺動体１０３は、中間レール４に押圧されながら、付勢バネ１０２の付勢力に抗して後側に摺動する。そして、係止突起７５が、係止部材７の係合部６５を収納側に通過した（図１０に示す状態。）ところで、弾性誘導部６３の弾性変形の復元力により、操作部６４は元の状態に復元し、スライドレール１００は、最短縮小状態となる（図１１に示す状態。）。 Further, when the moving side rail 2 is housed, the sliding body 103 slides to the rear side against the urging force of the urging spring 102 while being pressed by the intermediate rail 4. Then, when the locking projection 75 has passed the engaging portion 65 of the locking member 7 to the storage side (the state shown in FIG. 10), the operating portion 64 is restored due to the restoring force of the elastic deformation of the elastic guiding portion 63. The slide rail 100 is restored to the state shown in the above state, and the slide rail 100 is in the shortest reduced state (the state shown in FIG. 11).

このように、インナー中間レール後端ストッパー４４ａの後端が、摺動体１０３の前面に当接し、移動側レール後端ストッパー２２０の後端がアウター中間レール後端ストッパー４４ｂの前面に当接し、係止部材７の係止突起７５の前面が、ロック部材６の係合面６５ａに当接し、収納係止状態、すなわちロック状態となる。
このロック状態において、中間レール４は付勢装置１０により前方に移動するように付勢されているため、該付勢力によって、係止部材７の係止突起７５の前面の当接係止部７５２を、ロック部材６の係合面６５ａに確実に当接させることができる。
そのため、前述の係止突起７５が、係止部材７の係合部６５に対して収納側に通過した状態時より、付勢力により移動側レールは若干前方に移動して、図１１に示す係止突起７５の前面が係合面６５ａに当接した状態となる。 In this way, the rear end of the inner intermediate rail rear end stopper 44a abuts on the front surface of the sliding body 103, and the rear end of the moving side rail rear end stopper 220 abuts on the front surface of the outer intermediate rail rear end stopper 44b. The front surface of the locking projection 75 of the stopping member 7 comes into contact with the engaging surface 65a of the locking member 6, and is in a stowed locked state, that is, a locked state.
In this locked state, since the intermediate rail 4 is urged to move forward by the urging device 10, the urging force causes the contact locking portion 752 on the front surface of the locking projection 75 of the locking member 7. Can be reliably brought into contact with the engaging surface 65a of the lock member 6.
Therefore, the moving side rail moves slightly forward due to the urging force from the state where the locking projection 75 has passed to the storage side with respect to the engaging portion 65 of the locking member 7, and the engagement shown in FIG. 11 is shown. The front surface of the stop protrusion 75 is in contact with the engaging surface 65a.

前述のとおり、ロック部材６の案内部６４ａと係止部材７の係止突起７５は上下対称に形成されているため、移動側レール２の収納時に、案内部６４ａの下面と係止突起７５の上面が接触する場合の他、案内部６４ａの上面と係止突起７５の下面が接触する場合がある。これらは、案内部６４ａと係止突起７５が接触する瞬間の位置関係によって決まるものであるが、いずれの場合においても収納係止状態とすることが可能なように上下対称形状としている。案内部６４ａの上面と係止突起７５の下面が接触する場合、上記説明の操作部６４の移動方向は、上記説明の上側に対して下側となる。
このように、本件実施例のロック装置は、上下対称形に形成されているため、スライドレール１００を左右兼用で使用することが可能となる。左右兼用であるため、メンテナンス用の部品の管理も左右で分ける必要がなく部品管理効率がよくなる利点もある。 As described above, since the guide portion 64a of the lock member 6 and the locking projection 75 of the locking member 7 are formed vertically symmetrically, the lower surface of the guide portion 64a and the locking projection 75 are formed when the moving side rail 2 is stored. In addition to the case where the upper surface comes into contact, the upper surface of the guide portion 64a may come into contact with the lower surface of the locking projection 75. These are determined by the positional relationship at the moment when the guide portion 64a and the locking projection 75 come into contact with each other, but in any case, the shape is vertically symmetrical so that the storage and locking state can be achieved. When the upper surface of the guide portion 64a and the lower surface of the locking projection 75 come into contact with each other, the moving direction of the operation portion 64 described above is lower than the upper side described above.
As described above, since the lock device of the present embodiment is formed in a vertically symmetrical shape, the slide rail 100 can be used for both left and right. Since it is used for both left and right, it is not necessary to divide the management of maintenance parts into left and right, and there is an advantage that parts management efficiency is improved.

次に、ロック状態から、例えば棚板と連結された移動側レール２を引き出すときは、棚板の上面と操作部６４の下面を指先で摘むようにして、操作部６４を上方に移動させると、ロック部材６の弾性誘導部６３が弾性変形しながら、係合部６５が係止部材７の係止突起７５の上方に位置する（図１２に示す状態。）。尚、前述のとおり、係止部材７とロック部材６は上下方向対称に形成されているので、対向するスライドレール１００、１００に兼用して使用された状態であっても、左右いずれの操作部６４を同じ動作の上方に移動させることができる。 Next, when pulling out the moving side rail 2 connected to the shelf board from the locked state, for example, the upper surface of the shelf board and the lower surface of the operating portion 64 are grasped with a fingertip, and the operating portion 64 is moved upward to lock. The engaging portion 65 is located above the locking projection 75 of the locking member 7 while the elastic guiding portion 63 of the member 6 is elastically deformed (the state shown in FIG. 12). As described above, since the locking member 7 and the locking member 6 are formed symmetrically in the vertical direction, even if the locking member 7 and the locking member 6 are used in combination with the opposing slide rails 100 and 100, either the left or right operating unit is used. 64 can be moved above the same movement.

そして、係合部６５が係止部材７の係止突起７５の上方に位置すると、すなわち、係合部６５と係止突起７５の係合状態が解除された状態で、付勢装置１０の付勢力によって、中間レール４が前方に押し出される。中間レール４が前方に押し出されると、移動側レール後端ストッパー２２０の後端がアウター中間レール後端ストッパー４４ｂの前面に当接しているから、移動側レール２も前方に移動し、係止突起７５の上面に操作部６４の下面が押し付けられた状態で停止し、この状態でロック解除されたこととなる（図１３に示す状態。）。
したがって、付勢装置１０を有している場合は、ロック状態から、左右の操作部６４のみを上方あるいは下方に移動するだけで、ロック解除される。 Then, when the engaging portion 65 is located above the locking projection 75 of the locking member 7, that is, in a state where the engaging portion 65 and the locking projection 75 are disengaged, the urging device 10 is attached. The force pushes the intermediate rail 4 forward. When the intermediate rail 4 is pushed forward, the rear end of the moving side rail rear end stopper 220 is in contact with the front surface of the outer intermediate rail rear end stopper 44b, so that the moving side rail 2 also moves forward and the locking projection. The operation unit 64 was stopped in a state of being pressed against the upper surface of the operation unit 64, and the lock was released in this state (the state shown in FIG. 13).
Therefore, when the urging device 10 is provided, the lock is released only by moving the left and right operation units 64 upward or downward from the locked state.

本ロック装置は、付勢装置１０が無くともロック状態とすることが可能であるが、この場合は、ロック解除させる際、左右の操作部６４を操作した状態を維持し係合部６５と係止突起７５の係合状態が解除された状態のまま棚板等の移動部材を引き出すこととなるので、付勢装置１０を備えたほうが使い勝手がよい。 The lock device can be locked without the urging device 10, but in this case, when the lock is released, the left and right operation units 64 are maintained in the operated state and engaged with the engagement unit 65. Since the moving member such as the shelf board is pulled out while the engagement state of the stop protrusion 75 is released, it is more convenient to provide the urging device 10.

ロック解除後、そのまま、棚板を引き出すと、係止突起７５が操作部６４から離れ、弾性誘導部６３の弾性変形の復元力により、操作部６４は元の状態に復元する。この状態では、中間レール４のインナー中間レール４ａは、ロック部材６の弾性誘導部６３まで引き出されていないので、スライドレールの引き出す過程において、ロック部材６がインナー中間レール４ａに干渉することがない。
そして、さらに棚板を引き出すと、ロック部材６が、インナー中間レール４ａの基板４１ｂ、上下折曲縁４２ｂ、４２ｂで形成される空間内に位置した状態のまま、移動側レール２は最大伸長まで引き出され停止する。 When the shelf board is pulled out as it is after unlocking, the locking projection 75 is separated from the operating portion 64, and the operating portion 64 is restored to the original state by the restoring force of the elastic deformation of the elastic guiding portion 63. In this state, the inner intermediate rail 4a of the intermediate rail 4 is not pulled out to the elastic guide portion 63 of the lock member 6, so that the lock member 6 does not interfere with the inner intermediate rail 4a in the process of pulling out the slide rail. ..
Then, when the shelf plate is further pulled out, the moving side rail 2 is extended to the maximum while the lock member 6 is located in the space formed by the substrate 41b of the inner intermediate rail 4a and the upper and lower bent edges 42b and 42b. It is pulled out and stopped.

スライドレール１００は、最短縮小状態において、ロック部材６の操作部６４は、係合部６５の前方で係止部材７の固定基部７２、フランジ部７４と前後方向で部分的に重なり合っている。
このように設定することで、最短縮小状態で操作部６４を移動側レール２方向に曲げようとしても、該操作部６４が係止部材７の部分的に重なり合った箇所に当接し、操作部６４が必要以上に曲がらない。そのため、ロック部材６の破損を防ぐことができる。
尚、操作部６４の固定側レール１の方向に対する曲がりは、通常固定側レール１は、側板などに固定されるため、操作部６４が固定側レール１の方向に曲がると側板などに当たり大きく変形することが少ない。
したがって、係止部材７は、ロック部材６の左右方向の振れ止めの役割も有していることとなる。 In the shortest reduced state of the slide rail 100, the operation portion 64 of the lock member 6 partially overlaps the fixing base portion 72 and the flange portion 74 of the locking member 7 in the front-rear direction in front of the engaging portion 65.
By setting in this way, even if the operation unit 64 is to be bent in the two directions of the moving side rail in the shortest reduced state, the operation unit 64 comes into contact with the partially overlapped portion of the locking member 7, and the operation unit 64 Does not bend more than necessary. Therefore, it is possible to prevent the lock member 6 from being damaged.
As for the bending of the operation unit 64 with respect to the direction of the fixed side rail 1, since the fixed side rail 1 is usually fixed to the side plate or the like, when the operation unit 64 bends in the direction of the fixed side rail 1, it hits the side plate or the like and is greatly deformed. There are few things.
Therefore, the locking member 7 also has a role of a steady rest in the left-right direction of the locking member 6.

本スライドレールのロック装置は、本実施例のスライドレール形態だけでなく、図１４に示すアウター中間レールをインナー中間レールと同断面形状とし、移動側レールを固定側レールと同断面形状に形成したスライドレールであってもよい。
また、本スライドレールのロック装置は、本実施例のように、スライドレール（固定側レール）の基板１２が垂直となる縦使いだけではなく、スライドレール基板１２が水平となる横使いのスライドレールでも使用可能である。 In the lock device of the present slide rail, not only the slide rail form of the present embodiment but also the outer intermediate rail shown in FIG. 14 has the same cross-sectional shape as the inner intermediate rail, and the moving side rail has the same cross-sectional shape as the fixed side rail. It may be a slide rail.
Further, the lock device of the slide rail is not only a vertical use in which the substrate 12 of the slide rail (fixed side rail) is vertical as in the present embodiment, but also a horizontal slide rail in which the slide rail substrate 12 is horizontal. But it can be used.
