引出しの引込み装置及びエラー回復装置Drawer retractor and error recovery device
　本発明は、引出しを備えたキャビネット等における、引出しを自動的に引込む装置、及びその装置におけるエラー回復装置に関する。 The present invention relates to a device for automatically drawing a drawer in a cabinet or the like equipped with a drawer, and an error recovery device for the device.
　従来より、書類等を収納するキャビネットには、一般的に、スライドレール等により引出し動作を滑らかに行えるようにした引出しが備えられている。 2. Description of the Related Art Conventionally, a cabinet that stores documents and the like is generally provided with a drawer that allows a drawer operation to be smoothly performed by a slide rail or the like.
　近年、このようなキャビネットには、ユーザの利便性を向上させるために、例えば特許文献１に記載されているような、引出しを引き出した状態からある程度押し込むと、その後は自動的に引出しを引込む引込み装置を備えたものが見られるようになってきている。 In recent years, in order to improve the convenience of the user, such a cabinet has been described in Patent Document 1, for example. Some are equipped with devices.
　図１は、引出しの引込み装置を備えたキャビネットの一例を示す図である。図１において、キャビネットの本体であるキャビネット本体１には、引出し２と、引出し２をスライド可能に支持するためのスライドレール３と、引出し２を引き出した状態から途中まで押し込んだときに自動的にキャビネット本体１内に引込む引込み装置４００と、引込み装置４００と協働して引出し２をキャビネット本体１内に引込むストライカ５とが備えられている。 FIG. 1 is a diagram showing an example of a cabinet provided with a drawer retractor. In FIG. 1, a cabinet body 1, which is a cabinet body, is automatically provided with a drawer 2, a slide rail 3 for slidably supporting the drawer 2, and when the drawer 2 is pushed halfway from the pulled-out state. A retracting device 400 for retracting into the cabinet body 1 and a striker 5 for retracting the drawer 2 into the cabinet body 1 in cooperation with the retracting device 400 are provided.
　ここで、従来の引込み装置４００の構造について、図２を参照して説明する。図２は、引込み装置４００の構造及びその動作を示す図である。図２において、引込み装置４００は、引込み装置４００の本体である引込み装置本体４０１と、引込み装置本体４０１のスライド溝４０１ａにスライド自在に嵌合する２つのガイドピン４０２ａ，４０２ｂを備えるスライダ４０２と、スライダ４０２を引出し２を引込む方向に付勢する引っ張りバネ４０３と、引出し２が急激に引込まれることを防止するためのダンパ４０４とを備えている。 Here, the structure of the conventional retracting device 400 will be described with reference to FIG. FIG. 2 is a diagram showing the structure of the retractor 400 and its operation. In FIG. 2, the retracting device 400 includes a retracting device main body 401 that is a main body of the retracting device 400, and a slider 402 that includes two guide pins 402 a and 402 b that are slidably fitted in slide grooves 401 a of the retracting device main body 401. A tension spring 403 that urges the slider 402 in the direction in which the drawer 2 is retracted, and a damper 404 for preventing the drawer 2 from being abruptly pulled in are provided.
　図２Ａは、上記のように構成された引込み装置４００において、引出し２が矢印Ａの方向に押し込まれる途中の、引込み装置４００が作動する直前の状態を示している。図２Ａの状態から引出し２をさらに押し込むと、引出し２に固定されたストライカ５の爪５ａが、スライダ４０２の凸部４０２ｃに当たり凸部４０２ｃを図中右方向に押す。これにより、スライダ４０２は図中時計回転方向に回動し、スライド溝４０１ａの先端の立下り部４０１ｂに落ち込んでいたガイドピン４０２ａが、スライド溝４０１ａの水平部に押し上げられる。また、このときストライカ５の爪５ａにスライダ４０２の凸部４０２ｄが係合する。そのため、図２Ｂに示すように、スライダ４０２は、引っ張りバネ４０３の付勢力により、矢印Ｂ方向にスライドし、これに伴ってスライダ４０２に係合したストライカ５も矢印Ｂ方向にスライドする。結果として、ストライカ５に固定された引出し２が引っ張りバネ４０３の付勢力により、矢印Ｂ方向にスライドされることとなり、引出し２がキャビネット本体１内に自動的に引込まれることとなる。 FIG. 2A shows a state immediately before the drawing-in device 400 is activated while the drawing-out 2 is being pushed in the direction of arrow A in the drawing-in device 400 configured as described above. When the drawer 2 is further pushed in from the state of FIG. 2A, the claw 5a of the striker 5 fixed to the drawer 2 hits the convex part 402c of the slider 402 and pushes the convex part 402c to the right in the drawing. As a result, the slider 402 rotates in the clockwise direction in the figure, and the guide pin 402a that has fallen into the falling portion 401b at the tip of the slide groove 401a is pushed up to the horizontal portion of the slide groove 401a. At this time, the convex portion 402d of the slider 402 is engaged with the claw 5a of the striker 5. Therefore, as shown in FIG. 2B, the slider 402 slides in the arrow B direction by the urging force of the tension spring 403, and the striker 5 engaged with the slider 402 is also slid in the arrow B direction. As a result, the drawer 2 fixed to the striker 5 is slid in the direction of arrow B by the urging force of the tension spring 403, and the drawer 2 is automatically drawn into the cabinet body 1.

　上記のように構成される引込み装置４００においては、スライダ４０２が引っ張りバネ４０３の力によってスライドされるため、図３に示すように、引出し２の引込み始めの位置では引込み力が大きいが、引出し２がキャビネット本体１の奥に引込まれるにつれて、引っ張りバネ４０３が縮み、引込み力が小さくなる。この場合、書類などを収納するキャビネットでは、一つの引き出し２の重量が５０～６０Ｋｇにもなるため、引出し２が奥に引込まれたときの引っ張りバネ４０３の引っ張り力が不足し、引出し２が引込みの途中で止まってしまう場合があった。また、逆に、引出し２が奥に引込まれたときの引っ張りバネ４０３の引っ張り力を十分に確保しようとすると、引っ張りバネ４０３の引っ張り力を非常に強くする必要があり、ユーザが引出し２を引き出そうとしたときに、過度の引出し力が必要となる。 In the retraction device 400 configured as described above, since the slider 402 is slid by the force of the tension spring 403, the retraction force is large at the position of the retraction start of the retraction 2 as shown in FIG. Is pulled into the back of the cabinet body 1, the tension spring 403 contracts and the pulling force decreases. In this case, in a cabinet for storing documents, the weight of one drawer 2 is 50-60 kg, so that the pulling force of the tension spring 403 is insufficient when the drawer 2 is pulled back, and the drawer 2 is pulled in. There was a case where it stopped in the middle of. On the other hand, if it is attempted to sufficiently secure the pulling force of the tension spring 403 when the drawer 2 is pulled back, the pulling force of the tension spring 403 needs to be very strong, and the user pulls out the drawer 2. When trying, excessive pulling force is required.
　また、上記のように構成される引込み装置４００においては、何らかの原因でストライカ５の爪５ａとスライダ４０２の凸部４０２ｄの係合が外れるエラーが発生する場合があった。その場合、ストライカ５の爪５ａとスライダ４０２の凸部４０２ｄの係合を回復する必要があるが、上記の特許文献１にはこの係合を回復する構造も開示されている。 Further, in the retraction device 400 configured as described above, an error may occur in which the engagement between the claw 5a of the striker 5 and the convex portion 402d of the slider 402 is disengaged for some reason. In that case, it is necessary to recover the engagement between the claw 5a of the striker 5 and the convex portion 402d of the slider 402, but the above-mentioned Patent Document 1 also discloses a structure for recovering this engagement.
　しかしながら、特許文献１に記載の回復構造では、回復構造を構成する部材の形状及び構造が複雑であり、引込み装置のコストが高くなるという問題があった。 However, the recovery structure described in Patent Document 1 has a problem that the shape and structure of the members constituting the recovery structure are complicated, and the cost of the retracting device increases.
　従って、本発明は上述した課題に鑑みてなされたものであり、その目的は、引出しの引込み装置において、引出しが奥の方に引き込まれたときの引込み力の低下を防止することである。 Therefore, the present invention has been made in view of the above-described problems, and an object of the present invention is to prevent a pull-in force from being lowered when the drawer is pulled inward in the drawer drawing-in device.
　また、本発明の別の目的は、引出しの引込み装置において、単純な構造でエラーを回復できるようにすることである。 Another object of the present invention is to make it possible to recover an error with a simple structure in a drawer retractor.

　（第１の実施形態）
　図１は、本発明の第１の実施形態に係わる引出しの引込み装置４を備えたキャビネット（収納容器）の構成を示す図である。図１において、キャビネットの本体であるキャビネット本体（収納容器本体）１には、物品等を収納する引出し２と、引出し２をスライド可能に支持するためのスライドレール３と、引出し２を引き出した状態から途中まで押し込んだときに自動的にキャビネット本体１内に引込む引込み装置４と、引出し２に固定され引込み装置４と協働して引出し２をキャビネット本体１内に引込むストライカ５（係止部材）とが備えられている。なお、本実施形態では、スライドレール３には、アウターレール（外側レール）３ａと、インターレール（中間レール）３ｂと、インナーレール（内側レール）３ｃとを備える３段式のレールが用いられる。これは、２段式のレールでは、引出し２の奥側の一部分がキャビネット本体１の内側に残ってしまうので、引出し２の奥側の部分まで完全にキャビネット本体１から引き出せるようにするためである。 (First embodiment)
FIG. 1 is a view showing a configuration of a cabinet (storage container) provided with a drawer retracting device 4 according to the first embodiment of the present invention. In FIG. 1, a cabinet body (storage container body) 1 which is a cabinet body has a drawer 2 for storing articles, a slide rail 3 for slidably supporting the drawer 2, and a state in which the drawer 2 is pulled out. A retractor 4 that automatically pulls into the cabinet body 1 when it is pushed halfway, and a striker 5 (locking member) that is fixed to the drawer 2 and that pulls the drawer 2 into the cabinet body 1 in cooperation with the retractor 4 And are provided. In the present embodiment, the slide rail 3 is a three-stage rail including an outer rail (outer rail) 3a, an interrail (intermediate rail) 3b, and an inner rail (inner rail) 3c. This is because in the two-stage rail, a part on the back side of the drawer 2 remains inside the cabinet body 1 so that the part on the back side of the drawer 2 can be completely pulled out from the cabinet body 1. .
　図４は、本実施形態の引込み装置４の構造を示す図である。 FIG. 4 is a diagram showing the structure of the retracting device 4 of the present embodiment.
　図４において、引込み装置４は、引込み装置４の本体であり、キャビネット本体１に固定された引込み装置本体４１と、引込み装置本体４１のスライド溝４１ａにスライド自在に嵌合する２つのガイドピン４２ａ，４２ｂを備えるスライダ（第１の係合部材）４２と、スライダ４２を引出し２を引込む方向に付勢する引っ張りバネ（第１のバネ）４３と、引出し２が急激に引込まれることを防止するためのダンパ４４とを備えている。ダンパ４４のピストンの先端は、ガイドピン４２ｂに連結されている。本実施形態では、このような構成を備える引込み部を第１の引込み部１００と呼ぶこととする。第１の引込み部の構成は、図２に示した従来の引込み装置４００の構成と概略同じである。 In FIG. 4, the retracting device 4 is a main body of the retracting device 4. The retracting device main body 41 fixed to the cabinet body 1 and two guide pins 42 a that are slidably fitted in the slide grooves 41 a of the retracting device main body 41. , 42b, a slider (first engaging member) 42, a tension spring (first spring) 43 that urges the slider 42 in the direction in which the drawer 2 is retracted, and the drawer 2 is prevented from being drawn suddenly. And a damper 44 is provided. The tip of the piston of the damper 44 is connected to the guide pin 42b. In the present embodiment, the retracting portion having such a configuration is referred to as a first retracting portion 100. The configuration of the first retracting unit is substantially the same as the configuration of the conventional retracting device 400 shown in FIG.
　本実施形態の引込み装置４は、上記の第１の引込み部１００の下方に第２の引込み部１０１を備えている。この第２の引込み部１０１は、引込み装置本体４１のスライド溝４５ａにスライド自在に嵌合する２つのガイドピン４６ａ，４６ｂを備えるスライダ（第２の係合部材）４６と、スライダ４６を引出し２を引込む方向に付勢する引っ張りバネ（第２のバネ）４７と、引出し２が急激に引込まれることを防止するためのダンパ４８とを備えている。ダンパ４８のピストンの先端は、ガイドピン４６ｂに連結されている。また、ダンパ４８の後端部には、ブラケット４８ａが固定されており、このブラケット４８ａの中心穴が引込み装置本体４１に固定されたピン４１ｃに嵌合することにより、ダンパ４８は、引込み装置本体４１に対して矢印Ｅ方向に回動可能に支持されている。 The retracting device 4 of the present embodiment includes a second retracting portion 101 below the first retracting portion 100 described above. The second retracting portion 101 has a slider (second engaging member) 46 including two guide pins 46 a and 46 b slidably fitted in the slide groove 45 a of the retracting device main body 41, and pulls out the slider 46 2. A tension spring (second spring) 47 that urges the drawer 2 in the pulling direction, and a damper 48 for preventing the drawer 2 from being pulled suddenly. The tip of the piston of the damper 48 is connected to the guide pin 46b. Further, a bracket 48a is fixed to the rear end portion of the damper 48, and the damper 48 is connected to the pin 41c fixed to the retracting device main body 41 by the center hole of the bracket 48a. 41 is supported so as to be rotatable in the direction of arrow E with respect to 41.
　図４Ａは、上記のように構成された引込み装置４において、引出し２が矢印Ａの方向に押し込まれる途中の、引込み装置４が作動する直前の状態を示している。図４Ａの状態では、スライダ４２のガイドピン４２ａは、スライド溝４１ａの立下り部４１ｂに落ち込んでいるため、引っ張りバネ４３の引っ張り力に抗して、図４Ａに示す位置でロックされている。図４Ａの状態から引出し２をさらに押し込むと、引出し２に固定されたストライカ５の爪５ａが、スライダ４２の凸部４２ｃに当たり凸部４２ｃを図中右方向に押す。これにより、スライダ４２は図中時計回転方向に回動し、スライド溝４１ａの先端の立下り部４１ｂに落ち込んでいたガイドピン４２ａが、スライド溝４１ａの水平部に押し上げられる。また、このときストライカ５の爪５ａにスライダ４２の凸部４２ｄが係合する。そのため、図４Ｂに示すように、スライダ４２は、引っ張りバネ４３の付勢力により、矢印Ｂ方向にスライドし、これに伴ってスライダ４２に係合したストライカ５も矢印Ｂ方向にスライドする。結果として、ストライカ５に固定された引出し２が引っ張りバネ４３の付勢力により、矢印Ｂ方向にスライドされることとなり、引出し２がキャビネット本体１内に自動的に引込まれることとなる。 FIG. 4A shows a state immediately before the drawing-in device 4 is activated in the middle of the drawing-in device 2 being pushed in the direction of arrow A in the drawing-in device 4 configured as described above. In the state of FIG. 4A, the guide pin 42a of the slider 42 has fallen into the falling part 41b of the slide groove 41a, so that it is locked at the position shown in FIG. 4A against the pulling force of the tension spring 43. When the drawer 2 is further pushed in from the state of FIG. 4A, the claw 5a of the striker 5 fixed to the drawer 2 hits the convex part 42c of the slider 42 and pushes the convex part 42c to the right in the figure. As a result, the slider 42 rotates in the clockwise direction in the drawing, and the guide pin 42a that has fallen into the falling portion 41b at the tip of the slide groove 41a is pushed up to the horizontal portion of the slide groove 41a. At this time, the convex portion 42 d of the slider 42 is engaged with the claw 5 a of the striker 5. Therefore, as shown in FIG. 4B, the slider 42 slides in the arrow B direction by the urging force of the tension spring 43, and the striker 5 engaged with the slider 42 is also slid in the arrow B direction. As a result, the drawer 2 fixed to the striker 5 is slid in the direction of arrow B by the urging force of the tension spring 43, and the drawer 2 is automatically drawn into the cabinet body 1.
　次に、図４Ｂは、スライダ４２が引出し２を引込みながら、引出し２の引込みストローク（スライドストローク）の途中まで来て、第２の引込み部１０１を作動させる直前の状態を示している。図４Ｂの状態では、スライダ４６のガイドピン４６ａは、スライド溝４５ａの立下り部４５ｂに落ち込んでいるため、引っ張りバネ４７の引っ張り力に抗して、図４Ｂに示す位置でロックされている。図４Ｂの状態から引出し２（スライダ４２）が引っ張りバネ４３の力によりさらに引込まれると、スライダ４２の爪４２ｅが、スライダ４６の凸部４６ｃに当たり凸部４６ｃを図中右方向に押す。これにより、スライダ４６は図中時計回転方向に回動し、スライド溝４５ａの先端の立下り部４５ｂに落ち込んでいたガイドピン４６ａが、スライド溝４５ａの水平部に押し上げられる。また、このときスライダ４２の爪４２ｅにスライダ４６の凸部４６ｄが係合する。そのため、図４Ｃに示すように、スライダ４６は、引っ張りバネ４７の付勢力により、矢印Ｃ方向にスライドし、これに伴ってスライダ４２を介してスライダ４６に間接的に係合したストライカ５も矢印Ｃ方向にスライドする。結果として、ストライカ５に固定された引出し２が引っ張りバネ４３と４７の付勢力の合計の力により、矢印Ｃ方向にスライドされることとなり、引出し２がキャビネット本体１内に自動的に引込まれることとなる。 Next, FIG. 4B shows a state immediately before the second retracting portion 101 is actuated while the slider 42 is in the middle of the retracting stroke (sliding stroke) of the drawer 2 while retracting the drawer 2. In the state of FIG. 4B, the guide pin 46a of the slider 46 has fallen into the falling part 45b of the slide groove 45a, so that it is locked at the position shown in FIG. 4B against the pulling force of the tension spring 47. When the drawer 2 (slider 42) is further pulled by the force of the tension spring 43 from the state of FIG. 4B, the claw 42e of the slider 42 contacts the convex part 46c of the slider 46 and pushes the convex part 46c to the right in the drawing. As a result, the slider 46 rotates in the clockwise direction in the drawing, and the guide pin 46a that has fallen into the falling portion 45b at the tip of the slide groove 45a is pushed up to the horizontal portion of the slide groove 45a. At this time, the protrusion 46d of the slider 46 is engaged with the claw 42e of the slider 42. Therefore, as shown in FIG. 4C, the slider 46 slides in the direction of arrow C by the urging force of the tension spring 47, and the striker 5 indirectly engaged with the slider 46 via the slider 42 is also accompanied by the arrow. Slide in the C direction. As a result, the drawer 2 fixed to the striker 5 is slid in the direction of arrow C by the total force of the urging forces of the tension springs 43 and 47, and the drawer 2 is automatically drawn into the cabinet body 1. It will be.
　次に、ユーザが引き出し２を引き出す場合の動作について説明する。まず、ユーザが引出し２を、キャビネット本体１に完全に引込まれた状態から引き出し始めると、図４Ｃのような状態となる。この状態からさらに引出し２を引き出してスライダ４６がスライド溝４５ａの図中左側の端部まで到達すると、スライダ４２の爪４２ｅがスライダ４６の凸部４６ｄを図中左側に押すため、スライダ４６のガイドピン４６ａがスライド溝４５ａの立下り部４５ｂに落ち込む。これにより、スライダ４６は図４Ｂに示す位置でロックされる。これと同時に、スライダ４２の爪４２ｅとスライダ４６の凸部４６ｄの係合が外れ、スライダ４２には、引っ張りバネ４３の引っ張り力のみが作用することとなる。そして、図４Ｂの状態からさらに引出し２を引き出してスライダ４２がスライド溝４１ａの図中左側の端部まで到達すると、ストライカ５の爪５ａがスライダ４２の凸部４２ｄを図中左側に押すため、スライダ４２のガイドピン４２ａがスライド溝４１ａの立下り部４１ｂに落ち込む。これによりスライダ４２は図４Ａに示す位置でロックされる。これと同時に、ストライカ５の爪５ａとスライダ４２の凸部４２ｄの係合が外れ、ユーザは引出し２をストロークの最後まで自由に引き出せるようになる。 Next, the operation when the user pulls out the drawer 2 will be described. First, when the user starts pulling out the drawer 2 from a state where it is completely pulled into the cabinet body 1, the state shown in FIG. 4C is obtained. When the drawer 2 is further pulled out from this state and the slider 46 reaches the left end of the slide groove 45a in the drawing, the claw 42e of the slider 42 pushes the convex portion 46d of the slider 46 to the left in the drawing. The pin 46a falls into the falling part 45b of the slide groove 45a. As a result, the slider 46 is locked at the position shown in FIG. 4B. At the same time, the engagement between the claw 42e of the slider 42 and the convex portion 46d of the slider 46 is released, and only the tension force of the tension spring 43 acts on the slider 42. Then, when the drawer 2 is further pulled out from the state of FIG. 4B and the slider 42 reaches the left end of the slide groove 41a in the drawing, the claw 5a of the striker 5 pushes the convex portion 42d of the slider 42 to the left in the drawing. The guide pin 42a of the slider 42 falls into the falling part 41b of the slide groove 41a. As a result, the slider 42 is locked at the position shown in FIG. 4A. At the same time, the engagement between the claw 5a of the striker 5 and the projection 42d of the slider 42 is released, and the user can freely pull out the drawer 2 until the end of the stroke.
　図５は、本実施形態の引込み装置４における引出し２の引込み力と引込み量の関係を示した図である。図５に示すように、引出し２の引込み始めの位置では、引出し２の引込み力は、引っ張りバネ４３の引っ張り力により決まり、引出し２は引込み力ａで引込まれる。その後、引出し２が奥に引込まれるにつれて、引っ張りバネ４３が縮み、引出し２の引込み力はｂに低下する。しかし、図５のＡ点において、図４Ｃに示すように、第２の引込み部１０１が作動し、引っ張りバネ４３の引っ張り力ｂに引っ張りバネ４７の引っ張り力ｃが加わるため、この時点で引出し２の引込み力は、ｂ＋ｃとなる。すなわち、引出し２が引込みストロークの途中まで引込まれた時点で、引っ張りバネ４７の引っ張り力が追加されることとなり、引出し２がキャビネット１の奥の方に引込まれたときの引込み力を確保することが可能となる。また、ユーザが引出し２を引き出す場合は、図５のＡ点において、第２の引込み部１０１が解除されるため、引っ張りバネ４７の引っ張り力が働かなくなり、ユーザが引出し２を引き出すために過度の引出し力を必要とすることも無い。 FIG. 5 is a diagram showing the relationship between the drawing force and the drawing amount of the drawer 2 in the drawing device 4 of the present embodiment. As shown in FIG. 5, at the position where the drawer 2 starts to be retracted, the pulling force of the drawer 2 is determined by the pulling force of the pulling spring 43, and the drawer 2 is pulled by the pulling force a. Thereafter, as the drawer 2 is pulled back, the tension spring 43 contracts, and the pulling force of the drawer 2 decreases to b. However, at the point A in FIG. 5, as shown in FIG. 4C, the second retracting portion 101 operates, and the pulling force c of the pulling spring 47 is added to the pulling force b of the pulling spring 43. The retraction force is b + c. That is, when the drawer 2 is retracted to the middle of the retracting stroke, the pulling force of the tension spring 47 is added, and the pulling force when the drawer 2 is retracted toward the back of the cabinet 1 is secured. Is possible. In addition, when the user pulls out the drawer 2, the second retracting portion 101 is released at point A in FIG. 5, so that the pulling force of the tension spring 47 does not work, and the user cannot pull out the drawer 2 excessively. There is no need for pull-out force.
　（第１の実施形態の変形例）
　次に、図６は、上記の第１の実施形態の変形例を示した図である。図６に示す変形例では、図４に示した引込み装置４の構成に加えて、第２の引込み部１０１のさらに下方に、スライド溝５０ａと、スライダ５２と、引っ張りバネ５３を備える第３の引込み部１０２を備えている。第３の引込み部１０２の動作については、図４に示した第２の引込み部１０１の動作と全く同じであるので、説明は省略する。 (Modification of the first embodiment)
Next, FIG. 6 is a diagram showing a modification of the first embodiment. In the modification shown in FIG. 6, in addition to the configuration of the drawing device 4 shown in FIG. 4, a third groove provided with a slide groove 50 a, a slider 52, and a tension spring 53 further below the second drawing portion 101. A retraction part 102 is provided. The operation of the third retracting unit 102 is exactly the same as the operation of the second retracting unit 101 shown in FIG.
　図７は、この変形例における引出し２の引込み力と引込み量の関係を示した図である。図７に示すように、引出し２の引込み始めの位置では、引出し２の引込み力は、引っ張りバネ４３の引っ張り力により決まり、引出し２は引込み力ａで引込まれる。その後、引出し２が奥に引込まれるにつれて、引っ張りバネ４３が縮み、引出し２の引込み力はｂに低下する。しかし、図７のＡ点において、第２の引込み部１０１が作動し、引っ張りバネ４３の引っ張り力ｂに引っ張りバネ４７の引っ張り力ｃが加わるため、この時点で引出し２の引込み力は、ｂ＋ｃとなる。また、引出し２がさらに奥に引込まれると、引っ張りバネ４３の引込み力はｄに、引っ張りバネ４７の引込み力はｅに低下する。しかし、図７のＢ点において、第３の引込み部１０２が作動し、引っ張りバネ４３の引っ張り力ｄ、引っ張りバネ４７の引っ張り力ｅに引っ張りバネ５３の引っ張り力ｆが加わるため、この時点で引出し２の引込み力は、ｄ＋ｅ＋ｆとなる。 FIG. 7 is a diagram showing the relationship between the pull-in force of pull-out 2 and the pull-in amount in this modification. As shown in FIG. 7, in the position where the drawer 2 starts to be retracted, the pulling force of the drawer 2 is determined by the pulling force of the pulling spring 43, and the drawer 2 is pulled by the pulling force a. Thereafter, as the drawer 2 is pulled back, the tension spring 43 contracts, and the pulling force of the drawer 2 decreases to b. However, at the point A in FIG. 7, the second retracting portion 101 is operated, and the pulling force c of the pulling spring 47 is added to the pulling force b of the pulling spring 43. At this time, the pulling force of the drawer 2 is b + c. Become. When the drawer 2 is further pulled back, the pulling force of the tension spring 43 decreases to d, and the pulling force of the tension spring 47 decreases to e. However, at point B in FIG. 7, the third retracting portion 102 is operated, and the pulling force f of the pulling spring 53 is added to the pulling force d of the pulling spring 43 and the pulling force e of the pulling spring 47. The pulling force of 2 is d + e + f.
　このように、上記の変形例においても、引出し２が引込みストロークの途中まで引込まれた時点で、引っ張りバネ４７の引っ張り力が追加され、引出し２がさらに引込まれた時点で、引っ張りバネ５３の引っ張り力が追加されることとなり、引出し２がキャビネット１の奥の方に引込まれたときの引込み力を確保することが可能となる。 As described above, also in the above modification, when the drawer 2 is retracted to the middle of the retracting stroke, the tension force of the tension spring 47 is added, and when the drawer 2 is further retracted, the tension spring 53 is pulled. A force is added, and it becomes possible to secure a pulling force when the drawer 2 is pulled toward the back of the cabinet 1.
　なお、上記の第１の実施形態及び変形例では、引込み装置を第１と第２の引込み部の２段構成、または第１乃至第３の引込み部の３段構成として説明したが、これ以上の多段の構成としてもよいことは言うまでも無い。 In the first embodiment and the modification described above, the retracting device has been described as a two-stage configuration of the first and second retracting portions, or a three-stage configuration of the first to third retracting portions. It goes without saying that a multi-stage configuration may be used.
　（第１の実施形態の効果）
　次に、第１の実施形態の効果について説明する。本実施形態では、既に述べたように、引出しの引込み装置において、引出し２がキャビネット本体１にある程度引込まれた状態での引込み力の低下を防止する効果のほかに、以下のような効果がある。その効果について説明する。 (Effects of the first embodiment)
Next, the effect of the first embodiment will be described. In the present embodiment, as described above, in the drawer drawing-in device, in addition to the effect of preventing the pull-in force from being lowered when the drawer 2 is pulled into the cabinet body 1 to some extent, the following effects are obtained. . The effect will be described.
　図８は、キャビネット本体１から引出し２が引き出される様子を示した図である。本実施形態では、既に述べたように引出し２全体をキャビネット本体１から引き出すことを可能にするために、３段式のスライドレール３を用いている。このような３段式のスライドレールでは、例えば、インターレール（中間レール）３ｂがアウターレール（外側レール）３ａ内に留まったままの状態でインナーレール（内側レール）３ｃが先に引き出されると、アウターレール３ａの先端３ａ－１に過度の荷重がかかり、スライドレールが破壊される場合がある。そのため、このような３段式のスライドレールでは、まずアウターレール３ａからインターレール３ｂが引き出され、その後にインターレール３ｂからインナーレール３ｃが引き出されるという順番で各レールが引き出される必要がある。 FIG. 8 is a diagram showing a state in which the drawer 2 is pulled out from the cabinet body 1. In the present embodiment, as described above, the three-stage slide rail 3 is used to enable the drawer 2 to be pulled out from the cabinet body 1 as described above. In such a three-stage slide rail, for example, when the inner rail (inner rail) 3c is first pulled out while the interrail (intermediate rail) 3b remains in the outer rail (outer rail) 3a, An excessive load may be applied to the tip 3a-1 of the outer rail 3a, and the slide rail may be broken. Therefore, in such a three-stage slide rail, it is necessary to first draw out the rails in the order in which the interrail 3b is drawn from the outer rail 3a and then the inner rail 3c is drawn from the interrail 3b.
　図９は、スライドレール３の各レールが順番に引き出されるようにするための機構を示す図である。また、図１０はスライドレール３を図９の矢印Ｅ方向から見た図である。 FIG. 9 is a diagram showing a mechanism for pulling out the rails of the slide rail 3 in order. FIG. 10 is a view of the slide rail 3 as seen from the direction of arrow E in FIG.
　図９、図１０において、インターレール３ｂはキャビネット本体１に固定されたアウターレール３ａに対してベアリング１２５によりスライド自在に支持され、引出し２に固定されたインナーレール３ｃはインターレール３ｂに対してベアリング１２６によりスライド自在に支持されている。インターレール３ｂの上面には回転軸３ｂ－１が固定されており、この回転軸３ｂ－１には、ロック部材１２０の一端が回動自在に支持されている。ロック部材１２０の他端には、重り１２１ａと係止ピン１２１が設けられており、この係止ピン１２１がインターレール３ｂの上面に形成された長穴３ｂ－２に入り込み、この長穴３ｂ－２の範囲内で移動することにより、ロック部材１２０の回動量が制限されている。また、ロック部材１２０の先端部には、係止突起１２２が形成されており、インナーレール３ｃの内側には、係止突起１２２と係合する凸部３ｃ－２が形成されている。なお、ロック部材１２０は、合成樹脂などの弾性を有する材料から形成されている。 9 and 10, the interrail 3b is slidably supported by a bearing 125 with respect to the outer rail 3a fixed to the cabinet body 1, and the inner rail 3c fixed to the drawer 2 is a bearing with respect to the interrail 3b. 126 is slidably supported. A rotating shaft 3b-1 is fixed to the upper surface of the interrail 3b, and one end of a lock member 120 is rotatably supported on the rotating shaft 3b-1. A weight 121a and a locking pin 121 are provided at the other end of the locking member 120. The locking pin 121 enters into a long hole 3b-2 formed on the upper surface of the interrail 3b, and this long hole 3b- By moving within the range of 2, the amount of rotation of the lock member 120 is limited. A locking projection 122 is formed at the tip of the lock member 120, and a convex portion 3c-2 that engages with the locking projection 122 is formed inside the inner rail 3c. The lock member 120 is made of an elastic material such as synthetic resin.
　このように構成されるスライドレール３においては、各レールを引き出すときに、図９Ａに示すように、インナーレール３ｃの凸部３ｃ－２がロック部材１２０の係止突起１２２に突き当たり、インナーレール３ｃがインターレール３ｂから引き出されることが阻止される。そのため、インターレール３ｂが先にアウターレール３ａから引き出される。その後、インターレール３ｂがアウターレール３ａから完全に引き出されると、ロック部材１２０が弾性を有する材料からなるため、ユーザが引出し２を引き出す力によりインナーレール３ｃの凸部３ｃ－２がロック部材１２０の係止突起１２２を乗り越え、インナーレール３ｃがインターレール３ｂから引き出される。なお、インナーレール３ｃがインターレール３ｂから引き出されるときには、ロック部材１２０は図９Ａに示すように長穴３ｂ－２の範囲内で重り１２１ａの重みで反時計回転方向に回動し、係止突起１２２が起き上がるので、インナーレール３ｃをインターレール３ｂから引き出すときの抵抗力は大きくなる。 In the slide rail 3 configured as described above, when each rail is pulled out, as shown in FIG. 9A, the convex portion 3c-2 of the inner rail 3c abuts against the locking projection 122 of the lock member 120, and the inner rail 3c. Is prevented from being pulled out from the interrail 3b. Therefore, the interrail 3b is pulled out from the outer rail 3a first. Thereafter, when the interrail 3b is completely pulled out from the outer rail 3a, the lock member 120 is made of a material having elasticity, so that the convex portion 3c-2 of the inner rail 3c is moved by the force with which the user pulls out the drawer 2 The inner rail 3c is pulled out from the interrail 3b over the locking projection 122. When the inner rail 3c is pulled out from the interrail 3b, the lock member 120 rotates counterclockwise with the weight of the weight 121a within the range of the elongated hole 3b-2 as shown in FIG. Since 122 rises, the resistance force when pulling out the inner rail 3c from the interrail 3b increases.
　一方、スライドレール３において、各レールを押し込むときには、まずインナーレール３ｃがインターレール３ｂに引込まれ、インナーレール３ｃの凸部３ｃ－２がロック部材１２０の係止突起１２２を乗り越える。このとき、ロック部材１２０は通常は重り１２１ａの重みで図９Ａに示した状態にあるが、インナーレール３ｃの凸部３ｃ－２がロック部材１２０の係止突起１２２に突き当たることにより、ロック部材１２０は図９Ｂに示すように時計回転方向に回動し、係止突起１２２が寝るので、インナーレール３ｃをインターレール３ｂに押し込む抵抗力は小さくなる。なお、長穴３ｂ－２の上端部は、ロック部材１２０の係止突起１２２がインナーレール３ｃの凸部３ｃ－２に押されて時計回転方向に傾いたときに係止ピン１２１に対して逃げているので、インナーレール３ｃの凸部３ｃ－２は、係止突起１２２の抵抗力が小さい状態で係止突起１２２を乗り越えることができる。その後、インターレール３ｂがアウターレール３ａに引込まれ、インターレール３ｂがストッパ３ａ－１に突き当たって停止する。 On the other hand, when each rail is pushed into the slide rail 3, the inner rail 3c is first drawn into the interrail 3b, and the convex portion 3c-2 of the inner rail 3c gets over the locking projection 122 of the lock member 120. At this time, the lock member 120 is normally in the state shown in FIG. 9A by the weight of the weight 121a. However, when the convex portion 3c-2 of the inner rail 3c abuts against the locking protrusion 122 of the lock member 120, 9B is rotated clockwise as shown in FIG. 9B, and the locking projection 122 lies, so that the resistance force for pushing the inner rail 3c into the interrail 3b is reduced. The upper end portion of the long hole 3b-2 escapes from the locking pin 121 when the locking projection 122 of the lock member 120 is pushed by the convex portion 3c-2 of the inner rail 3c and tilts clockwise. Therefore, the protrusion 3c-2 of the inner rail 3c can get over the locking projection 122 in a state where the resistance force of the locking projection 122 is small. Thereafter, the interrail 3b is drawn into the outer rail 3a, and the interrail 3b hits the stopper 3a-1 and stops.
　このように構成される３段式のスライドレール３を用いる本実施形態のキャビネットにおいては、引出し２を収納するとき、言い換えれば引込み装置４が引き出し２を引込むとき、上記のようにインナーレール３ｃが引込まれるときに、インナーレール３ｃの凸部３ｃ－２がロック部材１２０の係止突起１２２を乗り越える抵抗が発生する。すなわち、引込み装置４の引込み動作の途中で引込みの抵抗が発生することとなる。この場合、本実施形態の引込み装置では、例えば、図４における第２の引込み部１０１が作動する位置（図５におけるＡ点の位置）を、この引込み抵抗が発生する位置の直前に合わせておけば、第２の引込み部１０１により引込み力が強くなるので、この引込み抵抗に打ち勝つことが可能となる。 In the cabinet of the present embodiment using the three-stage slide rail 3 configured as described above, when the drawer 2 is stored, in other words, when the retracting device 4 retracts the drawer 2, the inner rail 3c is as described above. When the inner rail 3c is pulled in, a resistance is generated in which the protrusion 3c-2 of the inner rail 3c gets over the locking protrusion 122 of the lock member 120. That is, a pull-in resistance is generated during the pull-in operation of the pull-in device 4. In this case, in the retracting device of the present embodiment, for example, the position where the second retracting portion 101 in FIG. 4 operates (the position of the point A in FIG. 5) can be set immediately before the position where the retracting resistance is generated. In this case, the pull-in force is increased by the second pull-in portion 101, so that the pull-in resistance can be overcome.
　次に、図１１は、複数段の引出しを備えるキャビネットにおいて、一つの引出しを引き出したときに、他の引出しが引き出せないようにロックする装置の構成を示す図である。書類などの重量物を収納する引出しを複数段備えるキャビネットでは、複数の引出しが同時に引き出されると、その重量によりキャビネット本体１が倒れる可能性がある。そのためこのようなロック装置が必要となる。 Next, FIG. 11 is a diagram showing a configuration of a device that locks so that when one drawer is pulled out, the other drawer cannot be pulled out in a cabinet having a plurality of drawers. In a cabinet having a plurality of drawers for storing heavy objects such as documents, if a plurality of drawers are pulled out simultaneously, the cabinet body 1 may fall due to the weight. Therefore, such a locking device is necessary.
　図１１において、ロック装置２００は、ロック装置の本体である基板２０１と、基板２０１上の各引出し２の位置に対応して設けられた回動部材２０２と、基板２０１に形成され、回動部材２０２に設けられたピン２０２ｂに嵌合してピン２０２ｂの回動範囲、つまりは回動部材２０２の回動範囲を制限する円弧状の溝２０６と、基板２０１の上下に渡って張り渡されたワイヤ２０３と、ワイヤ２０３を引っ張る引っ張りバネ２０４と、引っ張りバネ２０４を固定する固定部材２０５とを備えて構成される。 In FIG. 11, the lock device 200 includes a substrate 201 that is a main body of the lock device, a rotation member 202 provided corresponding to the position of each drawer 2 on the substrate 201, and a rotation member formed on the substrate 201. An arcuate groove 206 that is fitted to a pin 202b provided in 202 and restricts the rotation range of the pin 202b, that is, the rotation range of the rotation member 202, and is stretched across the substrate 201. The wire 203, a tension spring 204 that pulls the wire 203, and a fixing member 205 that fixes the tension spring 204 are provided.
　このように構成されるロック装置２００においては、図１１Ｂに示すように、複数の引出しのうち一つの引出し２を引き出すと、引出し２に設けられたペグ２ａが回動部材２０２の端部２０２ａを押し、回動部材２０２が時計回転方向に回転する。この回転により、回動部材２０２のピン２０２ｂが円弧状の溝２０６の下端の位置まで回動する。また、同時にピン２０２ｂが、上下に張り渡されたワイヤ２０３を図１１Ｂに示すように引っ張る。この状態では、ピン２０２ｂの回動角度αが１００°程度であるので、ワイヤ２０３の張力により、ピン２０２ｂは回動先の位置で固定される。そして、この引張りにより引っ張りバネ２０４が引き伸ばされ、固定部材２０５が基板２０１に固定されたストッパ２０８に突き当たる。この状態では、ワイヤ２０３はこれ以上伸びることができず、他の引出しに対応して設けられた回動部材２０２のピン２０２ｂは、ワイヤ２０３に突き当たって回動することができず、引出し２のペグ２ａが回動部材２０２に突き当たって動くことができない。このような動作により、一つの引出しを引き出したときに他の引出しが引き出されることが防止される。 In the locking device 200 configured as described above, as shown in FIG. 11B, when one drawer 2 is pulled out of the plurality of drawers, the peg 2a provided on the drawer 2 causes the end portion 202a of the rotating member 202 to move. Pushing and rotating member 202 rotates in the clockwise direction. By this rotation, the pin 202b of the rotating member 202 is rotated to the position of the lower end of the arc-shaped groove 206. At the same time, the pin 202b pulls the wire 203 stretched up and down as shown in FIG. 11B. In this state, since the rotation angle α of the pin 202b is about 100 °, the pin 202b is fixed at the rotation destination position by the tension of the wire 203. Then, the tension spring 204 is extended by this tension, and the fixing member 205 abuts against the stopper 208 fixed to the substrate 201. In this state, the wire 203 cannot extend any more, and the pin 202b of the rotating member 202 provided corresponding to the other drawer cannot be rotated by striking the wire 203. The peg 2a cannot hit the rotating member 202 and move. Such an operation prevents another drawer from being pulled out when one drawer is pulled out.
　このように構成されるロック装置を用いる本実施形態のキャビネットにおいては、引出し２を収納するとき、言い換えれば引込み装置４が引き出し２を引込むとき、その引込みの最後において回動部材２０２を図１１Ｂに示した回動位置から元の位置に戻すための抵抗が発生する。すなわち、引込み装置４の引込み動作の途中で引込みの抵抗が発生することとなる。この場合、本実施形態の引込み装置では、例えば、図４における第２の引込み部１０１が作動する位置（図５におけるＡ点の位置）または図６における第３の引込み部１０２が作動する位置（図７におけるＢ点の位置）を、この引込み抵抗が発生する位置の直前に合わせておけば、第２の引込み部１０１または第３の引込み部１０２により引込み力が強くなるので、この引込み抵抗に打ち勝つことが可能となる。 In the cabinet of the present embodiment using the lock device configured as described above, when the drawer 2 is stored, in other words, when the retracting device 4 retracts the drawer 2, the rotating member 202 is shown in FIG. 11B at the end of the retracting. Resistance for returning from the rotation position shown to the original position is generated. That is, a pull-in resistance is generated during the pull-in operation of the pull-in device 4. In this case, in the retracting device of this embodiment, for example, the position at which the second retracting part 101 in FIG. 4 operates (the position of the point A in FIG. 5) or the position at which the third retracting part 102 in FIG. 6 operates ( If the position of point B in FIG. 7 is set immediately before the position where the pull-in resistance is generated, the pull-in force is increased by the second pull-in part 101 or the third pull-in part 102. It will be possible to overcome.
　以上説明したように、本実施形態の引込み装置４によれば、ユーザが引出し２を引き出す力を過度に大きくすること無く、引出しが奥の方に引き込まれたときの引込み力の低下を防止することが可能となる。 As described above, according to the retracting device 4 of the present embodiment, the pulling force is prevented from being lowered when the drawer is pulled inward without excessively increasing the force with which the user pulls out the drawer 2. It becomes possible.
　なお、上記の実施形態では、ストライカ５を引出し２に固定し、引込み装置４をキャビネット本体１に固定するように説明したが、逆にストライカ５をキャビネット本体１に固定し、引込み装置４を引き出しに固定するようにしても同様の効果が得られる。 In the above embodiment, the striker 5 is fixed to the drawer 2 and the retracting device 4 is fixed to the cabinet body 1. However, the striker 5 is fixed to the cabinet body 1 and the retracting device 4 is pulled out. The same effect can be obtained even if it is fixed to.
　（第２の実施形態）
　図１２は、第２の実施形態の引込み装置４の構造を示す図である。なお、図１２では、第１の実施形態を示す図４における各部に対応する同様の機能を有する部分には、同一の符号を付している。 (Second Embodiment)
FIG. 12 is a diagram illustrating a structure of the retracting device 4 according to the second embodiment. In FIG. 12, parts having the same functions corresponding to the respective parts in FIG. 4 showing the first embodiment are denoted by the same reference numerals.
　図１２において、引込み装置４は、引込み装置４の本体であり、キャビネット１に固定された引込み装置本体４１と、引込み装置本体４１のスライド溝４１ａにスライド自在に嵌合する２つのガイドピン４２ａ，４２ｂを備えるスライダ（第１の係合部材）４２と、スライダ４２を引出し２を引込む方向に付勢する引っ張りバネ４３と、引出し２が急激に引込まれることを防止するためのダンパ４４とを備えている。ダンパ４４のピストンの先端は、ガイドピン４２ｂに連結されている。本実施形態では、このような構成を備える引込み部を第１の引込み部１００と呼ぶこととする。第１の引込み部の構成は、図２に示した従来の引込み装置４００の構成と概略同じである。 In FIG. 12, the retracting device 4 is a main body of the retracting device 4. The retracting device main body 41 fixed to the cabinet 1 and two guide pins 42 a that are slidably fitted in the slide grooves 41 a of the retracting device main body 41. A slider (first engaging member) 42 provided with 42b, a tension spring 43 that urges the slider 42 in the direction in which the drawer 2 is pulled in, and a damper 44 for preventing the drawer 2 from being pulled in suddenly. I have. The tip of the piston of the damper 44 is connected to the guide pin 42b. In the present embodiment, the retracting portion having such a configuration is referred to as a first retracting portion 100. The configuration of the first retracting unit is substantially the same as the configuration of the conventional retracting device 400 shown in FIG.
　本実施形態の引込み装置４は、上記の第１の引込み部１００の下方に第２の引込み部１０１を備えている。この第２の引込み部１０１は、引込み装置本体４１のスライド溝４５ａにスライド自在に嵌合する２つのガイドピン４６ａ，４６ｂを備えるスライダ４６（第２の係合部材）と、スライダ４６を引出し２を引込む方向に付勢する引っ張りバネ４７と、引出し２が急激に引込まれることを防止するためのダンパ４８とを備えている。ダンパ４８のピストンの先端は、ガイドピン４６ｂに連結されている。また、ダンパ４８の後端部には、ブラケット４８ａが固定されており、このブラケット４８ａの中心穴が引込み装置本体４１に固定されたピン４１ｃに嵌合することにより、ダンパ４８は、引込み装置本体４１に対して矢印Ｅ方向に回動可能に支持されている。 The retracting device 4 of the present embodiment includes a second retracting portion 101 below the first retracting portion 100 described above. The second retracting portion 101 has a slider 46 (second engaging member) including two guide pins 46 a and 46 b slidably fitted in the slide groove 45 a of the retracting device main body 41, and pulls out the slider 46 2. Are provided with a tension spring 47 that urges the drawer 2 in the pulling direction, and a damper 48 for preventing the drawer 2 from being pulled suddenly. The tip of the piston of the damper 48 is connected to the guide pin 46b. Further, a bracket 48a is fixed to the rear end portion of the damper 48, and the damper 48 is connected to the pin 41c fixed to the retracting device main body 41 by the center hole of the bracket 48a. 41 is supported so as to be rotatable in the direction of arrow E with respect to 41.
　図１２Ａは、上記のように構成された引込み装置４において、引出し２が矢印Ａの方向に押し込まれる途中の、引込み装置４が作動する直前の状態を示している。図１２Ａの状態では、スライダ４２のガイドピン４２ａは、スライド溝４１ａの立下り部４１ｂに落ち込んでいるため、引っ張りバネ４３の引っ張り力に抗して、図１２Ａに示す位置でロックされている。図１２Ａの状態から引出し２をさらに押し込むと、引出し２に固定されたストライカ５の爪５ａが、スライダ４２の凸部４２ｃに当たり凸部４２ｃを図中右方向に押す。これにより、スライダ４２は図中時計回転方向に回動し、スライド溝４１ａの先端の立下り部４１ｂに落ち込んでいたガイドピン４２ａが、スライド溝４１ａの水平部に押し上げられる。また、このときストライカ５の爪５ａにスライダ４２の凸部４２ｄが係合する。そのため、図１２Ｂに示すように、スライダ４２は、引っ張りバネ４３の付勢力により、矢印Ｂ方向にスライドし、これに伴ってスライダ４２に係合したストライカ５も矢印Ｂ方向にスライドする。結果として、ストライカ５に固定された引出し２が引っ張りバネ４３の付勢力により、矢印Ｂ方向にスライドされることとなり、引出し２がキャビネット本体１内に自動的に引込まれることとなる。 FIG. 12A shows a state immediately before the retracting device 4 is in operation while the drawer 2 is being pushed in the direction of the arrow A in the retracting device 4 configured as described above. In the state of FIG. 12A, the guide pin 42 a of the slider 42 has fallen into the falling portion 41 b of the slide groove 41 a, and is locked at the position shown in FIG. 12A against the pulling force of the tension spring 43. When the drawer 2 is further pushed in from the state of FIG. 12A, the claw 5a of the striker 5 fixed to the drawer 2 hits the convex part 42c of the slider 42 and pushes the convex part 42c to the right in the figure. As a result, the slider 42 rotates in the clockwise direction in the drawing, and the guide pin 42a that has fallen into the falling portion 41b at the tip of the slide groove 41a is pushed up to the horizontal portion of the slide groove 41a. At this time, the convex portion 42 d of the slider 42 is engaged with the claw 5 a of the striker 5. Therefore, as shown in FIG. 12B, the slider 42 slides in the arrow B direction by the urging force of the tension spring 43, and the striker 5 engaged with the slider 42 is also slid in the arrow B direction. As a result, the drawer 2 fixed to the striker 5 is slid in the direction of arrow B by the urging force of the tension spring 43, and the drawer 2 is automatically drawn into the cabinet body 1.
　次に、図１２Ｂは、スライダ４２が引出し２を引込みながら、引出し２の引込みストロークの途中まで来て、第２の引込み部１０１を作動させる直前の状態を示している。図１２Ｂの状態では、スライダ４６のガイドピン４６ａは、スライド溝４５ａの立下り部４５ｂに落ち込んでいるため、引っ張りバネ４７の引っ張り力に抗して、図１２Ｂに示す位置でロックされている。図１２Ｂの状態から引出し２（スライダ４２）が引っ張りバネ４３の力によりさらに引込まれると、スライダ４２の爪４２ｅが、スライダ４６の凸部４６ｃに当たり凸部４６ｃを図中右方向に押す。これにより、スライダ４６は図中時計回転方向に回動し、スライド溝４５ａの先端の立下り部４５ｂに落ち込んでいたガイドピン４６ａが、スライド溝４５ａの水平部に押し上げられる。また、このときスライダ４２の爪４２ｅにスライダ４６の凸部４６ｄが係合する。そのため、図１２Ｃに示すように、スライダ４６は、引っ張りバネ４７の付勢力により、矢印Ｃ方向にスライドし、これに伴ってスライダ４２を介してスライダ４６に間接的に係合したストライカ５も矢印Ｃ方向にスライドする。結果として、ストライカ５に固定された引出し２が引っ張りバネ４３と４７の付勢力の合計の力により、矢印Ｃ方向にスライドされることとなり、引出し２がキャビネット本体１内に自動的に引込まれることとなる。 Next, FIG. 12B shows a state immediately before the slider 42 retracts the drawer 2 and reaches the middle of the drawing stroke of the drawer 2 to operate the second drawing portion 101. In the state of FIG. 12B, the guide pin 46a of the slider 46 has fallen into the falling portion 45b of the slide groove 45a, and is thus locked at the position shown in FIG. 12B against the pulling force of the tension spring 47. When the drawer 2 (slider 42) is further pulled by the force of the tension spring 43 from the state of FIG. 12B, the claw 42e of the slider 42 contacts the convex part 46c of the slider 46 and pushes the convex part 46c to the right in the figure. As a result, the slider 46 rotates in the clockwise direction in the drawing, and the guide pin 46a that has fallen into the falling portion 45b at the tip of the slide groove 45a is pushed up to the horizontal portion of the slide groove 45a. At this time, the protrusion 46d of the slider 46 is engaged with the claw 42e of the slider 42. Therefore, as shown in FIG. 12C, the slider 46 slides in the direction of the arrow C by the urging force of the tension spring 47, and the striker 5 indirectly engaged with the slider 46 via the slider 42 is also accompanied by the arrow. Slide in the C direction. As a result, the drawer 2 fixed to the striker 5 is slid in the direction of arrow C by the total force of the urging forces of the tension springs 43 and 47, and the drawer 2 is automatically drawn into the cabinet body 1. It will be.
　次に、ユーザが引き出し２を引き出す場合の動作について説明する。まず、ユーザが引出し２を、キャビネット本体１に完全に引込まれた状態から引き出し始めると、図１２Ｃのような状態となる。この状態からさらに引出し２を引き出してスライダ４６がスライド溝４５ａの図中左側の端部まで到達すると、スライダ４２の爪４２ｅがスライダ４６の凸部４６ｄを図中左側に押すため、スライダ４６のガイドピン４６ａがスライド溝４５ａの立下り部４５ｂに落ち込む。これにより、スライダ４６は図１２Ｂに示す位置でロックされる。これと同時に、スライダ４２の爪４２ｅとスライダ４６の凸部４６ｄの係合が外れ、スライダ４２には、引っ張りバネ４３の引っ張り力のみが作用することとなる。そして、図１２Ｂの状態からさらに引出し２を引き出してスライダ４２がスライド溝４１ａの図中左側の端部まで到達すると、ストライカ５の爪５ａがスライダ４２の凸部４２ｄを図中左側に押すため、スライダ４２のガイドピン４２ａがスライド溝４１ａの立下り部４１ｂに落ち込む。これによりスライダ４２は図１２Ａに示す位置でロックされる。これと同時に、ストライカ５の爪５ａとスライダ４２の凸部４２ｄの係合が外れ、ユーザは引出し２をストロークの最後まで自由に引き出せるようになる。 Next, the operation when the user pulls out the drawer 2 will be described. First, when the user starts to pull out the drawer 2 from the state where it is completely pulled into the cabinet body 1, the state shown in FIG. 12C is obtained. When the drawer 2 is further pulled out from this state and the slider 46 reaches the left end of the slide groove 45a in the drawing, the claw 42e of the slider 42 pushes the convex portion 46d of the slider 46 to the left in the drawing. The pin 46a falls into the falling part 45b of the slide groove 45a. As a result, the slider 46 is locked at the position shown in FIG. 12B. At the same time, the engagement between the claw 42e of the slider 42 and the convex portion 46d of the slider 46 is released, and only the tension force of the tension spring 43 acts on the slider 42. When the drawer 2 is further pulled out from the state of FIG. 12B and the slider 42 reaches the left end of the slide groove 41a in the drawing, the claw 5a of the striker 5 pushes the convex portion 42d of the slider 42 to the left in the drawing. The guide pin 42a of the slider 42 falls into the falling part 41b of the slide groove 41a. As a result, the slider 42 is locked at the position shown in FIG. 12A. At the same time, the engagement between the claw 5a of the striker 5 and the projection 42d of the slider 42 is released, and the user can freely pull out the drawer 2 until the end of the stroke.
　なお、本実施形態の引込み装置４における引出し２の引込み力と引込み量の関係は、既に第１の実施形態で説明した図５と同様になる。 Note that the relationship between the pull-in force of the drawer 2 and the pull-in amount in the pull-in device 4 of the present embodiment is the same as that in FIG. 5 already described in the first embodiment.
　（引込み装置のエラー回復動作）
　次に、上記の第２の実施形態のように構成される引込み装置にエラーが発生した場合の回復動作について説明する。 (Recovery device error recovery operation)
Next, the recovery operation when an error occurs in the retracting device configured as in the second embodiment will be described.
　本実施形態の引込み装置では、通常は、図１２Ｃに示す状態から引出し２を引き出していくと、ストライカ５に係合しているスライダ４２もストライカ５と共に引き出す方向に移動され、最終的には図１２Ａ及び図１３Ａに示すように、図中左側のストローク端部でロックされる。しかしながら、何らかの原因により、図１３Ｂに示すように、ストライカ５の爪５ａとスライダ４２の凸部４２ｄの係合が外れ、スライダ４２がキャビネット本体１の奥側に取り残されたまま、引き出し２（ストライカ５）がキャビネット本体１から引き出されてしまう場合（エラーの状態）がある。 In the retracting device of the present embodiment, normally, when the drawer 2 is pulled out from the state shown in FIG. 12C, the slider 42 engaged with the striker 5 is also moved in the pulling direction together with the striker 5. As shown in FIGS. 12A and 13A, it is locked at the stroke end on the left side in the drawing. However, for some reason, as shown in FIG. 13B, the engagement between the claw 5a of the striker 5 and the convex portion 42d of the slider 42 is disengaged, and the slider 2 is left behind on the cabinet body 1, and the drawer 2 (the striker 2 5) may be pulled out of the cabinet body 1 (error state).
　この場合、ストライカ５の爪５ａとスライダ４２の凸部４２ｄの係合を復帰させる必要がある。図１４は、この係合を復帰させる構造を示す図である。 In this case, it is necessary to return the engagement between the claw 5a of the striker 5 and the convex portion 42d of the slider 42. FIG. 14 is a diagram showing a structure for returning this engagement.
　本実施形態では、図１４Ａ及び図１４ＡのＤ－Ｄ断面図である図１４Ｂに示すように、ストライカ５の爪５ａには矢印Ａで示す進行方向に向かって次第に厚みが薄くなるように斜面５ａ－１が形成され、スライダ４２の凸部４２ｄにはＡで示す方向に向かって次第に厚みが厚くなる斜面４２ｄ－１が形成されている。そのため、図１３Ｂで示すエラーの状態から、ユーザが引出し２を押し込んでいくと、図６Ｂに示すようにストライカ５の爪５ａがスライダ４２の凸部４２ｄに次第に接近し、ストライカ５の爪５ａがスライダ４２の凸部４２ｄに接触すると、互いの斜面５ａ－１と４２ｄ－１がスライドして、図１４Ｃに示すように、ストライカ５の爪５ａがスライダ４２の凸部４２ｄを乗り越える。これにより、図１３Ｃに示すように、ストライカ５の爪５ａとスライダ４２の凸部４２ｄの係合が復帰される。したがって、この構造によれば、エラーが発生した場合でも、ユーザが引出し２を押し込む動作だけで、エラーを回復させることが可能となる。 In this embodiment, as shown in FIG. 14B, which is a DD cross-sectional view of FIGS. 14A and 14A, the claw 5a of the striker 5 has an inclined surface 5a so that the thickness gradually decreases in the traveling direction indicated by the arrow A. -1 is formed, and a slope 42d-1 that gradually increases in thickness in the direction indicated by A is formed on the convex portion 42d of the slider 42. Therefore, when the user pushes the drawer 2 out of the error state shown in FIG. 13B, the claw 5a of the striker 5 gradually approaches the convex portion 42d of the slider 42 as shown in FIG. 6B, and the claw 5a of the striker 5 When contacting the convex portion 42d of the slider 42, the inclined surfaces 5a-1 and 42d-1 slide, and the claw 5a of the striker 5 gets over the convex portion 42d of the slider 42 as shown in FIG. 14C. Thereby, as shown to FIG. 13C, engagement of the nail | claw 5a of the striker 5 and the convex part 42d of the slider 42 is reset. Therefore, according to this structure, even when an error occurs, it is possible to recover the error only by the user pushing the drawer 2.
　上記の説明は、第１の引込み部１００におけるエラー復帰動作の説明であるが、次に、第２の引込み部１０１にエラーが発生した場合の復帰動作について図１５を参照して説明する。 The above description is an explanation of the error recovery operation in the first pull-in unit 100. Next, the return operation when an error occurs in the second pull-in unit 101 will be described with reference to FIG.
　本実施形態の引込み装置では、通常は、図１２Ｃ、図１５Ａに示す状態から引出し２を引き出していくと、ストライカ５に係合しているスライダ４２が引き出す方向に移動され、スライダ４２に係合しているスライダ４６もスライダ４２と共に引き出す方向に移動される。そして、最終的には図１２Ａに示すように、スライダ４６は図中左側のストローク端部でロックされる。しかしながら、何らかの原因により、図１５Ｂに示すように、スライダ４２の爪４２ｅとスライダ４６の凸部４６ｄの係合が外れ、スライダ４６がキャビネット本体１の奥側に取り残されたまま、引き出し２（ストライカ５及びスライダ４２）がキャビネット本体１から引き出されてしまう場合（エラーの状態）がある。 In the retracting device of this embodiment, normally, when the drawer 2 is pulled out from the state shown in FIGS. 12C and 15A, the slider 42 engaged with the striker 5 is moved in the pulling direction and is engaged with the slider 42. The moving slider 46 is also moved in the pulling direction together with the slider 42. Finally, as shown in FIG. 12A, the slider 46 is locked at the stroke end on the left side in the drawing. However, for some reason, as shown in FIG. 15B, the engagement between the claw 42e of the slider 42 and the convex portion 46d of the slider 46 is disengaged, and the slider 46 is left behind in the cabinet body 1, and the drawer 2 (the striker 5 and the slider 42) may be pulled out from the cabinet body 1 (error state).
　この場合、スライダ４２の爪４２ｅとスライダ４６の凸部４６ｄの係合を復帰させる必要がある。図１５は、この係合を復帰させる構造を示す図である。 In this case, it is necessary to return the engagement between the claw 42e of the slider 42 and the projection 46d of the slider 46. FIG. 15 is a diagram showing a structure for returning this engagement.
　本実施形態では、図１５に示すように、第２の引込み部１０１を構成するスライド溝４５ａの図中右端部（引込み方向端部）には、立下り部４５ｃが形成されている。スライダ４６が図中右端部である引込み方向端部に位置している状態では、スライダ４６が引っ張りバネ４７により図中右方向に引っ張られていることから、図１５Ｂに示すようにスライダ４６は水平な状態にある。この状態で、ユーザが引出し２を押し込んでいくと、ストライカ５に係合しているスライダ４２が図中右方向に移動する。そして、スライダ４６の凸部４６ｄにスライダ４２の爪４２ｅが接触すると、図１５Ｃに示すように、スライダ４２の爪４２ｅがスライダ４６の凸部４６ｄの上端部に形成された斜面（引込み方向と反対側に形成された斜面）４６ｄ－１に乗り上げる。このとき、スライダ４６のガイドピン４６ｂがスライド溝４５ａの立下り部４５ｃに落ち込み、スライダ４６は引っ張りバネ４７の付勢力に抗して時計回転方向に回転される。そのため、スライダ４２の爪４２ｅは、スライダ４６の凸部４６ｄを乗り越えることが可能となる。なお、このとき、図１２に示したように第２の引込み部１０１を構成するダンパ４８が引込み装置本体４１に対して矢印Ｅ方向に回動可能に構成されているため、スライダ４６のガイドピン４６ｂがスライド溝４５ａの立ち下がり部４５ｃに落ち込むことに伴って、ダンパ４８は矢印Ｅの反時計回転方向に回動する。スライダ４２の爪４２ｅがスライダ４６の凸部４６ｄを乗り越えた後には、スライダ４６は、図１５Ｄに示すように、引っ張りバネ４７の引っ張り力により、水平状態に復帰する。以上の動作により、スライダ４２の爪４２ｅとスライダ４６の凸部４６ｄ（凸部４６ｄの右側の凹部）の係合が復帰される。したがって、この構造によれば、エラーが発生した場合でも、ユーザが引出し２を押し込む動作だけで、第２の引込み部１０１のエラーを回復させることが可能となる。 In this embodiment, as shown in FIG. 15, a falling portion 45c is formed at the right end portion (end portion in the drawing direction) of the slide groove 45a constituting the second drawing portion 101 in the drawing. In the state where the slider 46 is positioned at the end in the retracting direction, which is the right end in the figure, the slider 46 is pulled in the right direction in the figure by the tension spring 47, so that the slider 46 is horizontal as shown in FIG. 15B. It is in a state. When the user pushes in the drawer 2 in this state, the slider 42 engaged with the striker 5 moves to the right in the drawing. When the claw 42e of the slider 42 comes into contact with the convex portion 46d of the slider 46, as shown in FIG. 15C, the claw 42e of the slider 42 is formed on the inclined surface (opposite to the retracting direction) (Slope formed on the side) 46d-1. At this time, the guide pin 46b of the slider 46 falls into the falling part 45c of the slide groove 45a, and the slider 46 is rotated in the clockwise direction against the urging force of the tension spring 47. Therefore, the claw 42e of the slider 42 can get over the convex portion 46d of the slider 46. At this time, as shown in FIG. 12, the damper 48 constituting the second retracting portion 101 is configured to be rotatable in the direction of arrow E with respect to the retracting device main body 41. The damper 48 rotates in the counterclockwise direction of the arrow E as 46b falls into the falling portion 45c of the slide groove 45a. After the claw 42e of the slider 42 gets over the convex portion 46d of the slider 46, the slider 46 returns to the horizontal state by the pulling force of the pulling spring 47 as shown in FIG. 15D. Through the above operation, the engagement between the claw 42e of the slider 42 and the convex portion 46d of the slider 46 (the concave portion on the right side of the convex portion 46d) is restored. Therefore, according to this structure, even when an error occurs, it is possible to recover the error of the second pull-in unit 101 only by the user pushing the drawer 2.
　以上説明したように、本実施形態の引込み装置４によれば、引込み装置にエラーが発生した場合でも、ユーザが引出し２を押し込む動作だけで、エラーを回復させることが可能となる。 As described above, according to the retracting device 4 of the present embodiment, even when an error occurs in the retracting device, it is possible to recover the error only by the user pushing the drawer 2.
　なお、上記の第２の実施形態では、ストライカ５を引出し２に固定し、引込み装置４をキャビネット本体１に固定するように説明したが、逆にストライカ５をキャビネット本体１に固定し、引込み装置４を引き出しに固定するようにしても同様の効果が得られる。 In the second embodiment, the striker 5 is fixed to the drawer 2 and the retracting device 4 is fixed to the cabinet main body 1. Conversely, the striker 5 is fixed to the cabinet main body 1 and the retracting device is fixed. The same effect can be obtained by fixing 4 to the drawer.
