Description

本発明は、引き戸を閉まり際に強制的に減速させる制動機構を備えた引き戸装置において、引き戸の制動時における跳ね上がりを防止する跳ね上がり防止装置に関する。 The present invention relates to a jumping prevention device for preventing a jumping up at the time of braking of a sliding door in a sliding door device provided with a braking mechanism for forcibly decelerating when the sliding door is closed.

建物の開口を水平方向にスライドして開閉する引き戸には、戸先が戸枠に勢いよく衝突し、衝撃音や振動が発生したり、引き戸の跳ね返りが発生したりするという問題がある。この問題を解消するべく、引き戸を閉まり際に強制的に減速させる制動機構が引き戸装置に装備される（特許文献１）。 A sliding door that opens and closes by sliding the opening of a building in a horizontal direction has a problem in that the door tip collides with the door frame vigorously, causing impact sound and vibration, and rebounding of the sliding door. In order to solve this problem, the sliding door device is equipped with a braking mechanism that forcibly decelerates when the sliding door is closed (Patent Document 1).

しかし、制動機構を備えた引き戸装置においては、制動機構による制動力が作用し始めた瞬間に、図１２に示すように引き戸１１の戸先側が跳ね上がることがある。これが引き戸１１の閉まり際における異音の発生原因、さらには引き戸１１を支えている走行輪１１Ａ、１１Ｂやレール１２、ガイド部材１３Ａ、１３Ｂなどの損傷あるいは早期劣化の原因となる。この問題を解消するべく、引き戸１１の閉まり際に引き戸１１の戸先部分を上方から押さえ込むように構成した跳ね上がり防止装置が提案された（特許文献２）。 However, in the sliding door device provided with the braking mechanism, the door end side of the sliding door 11 may jump up as shown in FIG. 12 at the moment when the braking force by the braking mechanism starts to act. This causes abnormal noise when the sliding door 11 is closed, and further causes damage or early deterioration of the traveling wheels 11A and 11B, the rail 12, and the guide members 13A and 13B that support the sliding door 11. In order to solve this problem, there has been proposed a spring-up preventing device configured to press the door end portion of the sliding door 11 from above when the sliding door 11 is closed (Patent Document 2).

特許文献２に記載された跳ね上がり防止装置は、図１３に示すように、引き戸１１をスライド自在に案内する上側レール１２の終端位置に上側部材３１を、引き戸１１の戸先の上端に下側部材３２を、それぞれ取り付け、上側部材３１の下面に下側部材３２の上面を当接させることにより、引き戸１１の戸先側の上方への移動を阻止するものである。このため、引き戸１１が閉まる直前にならないと跳ね上がり防止機能を発揮し得ない。 As shown in FIG. 13, the splash prevention device described in Patent Document 2 includes an upper member 31 at the terminal position of the upper rail 12 that slidably guides the sliding door 11, and a lower member at the upper end of the door tip of the sliding door 11. 32 is attached, and the upper surface of the lower member 32 is brought into contact with the lower surface of the upper member 31, thereby preventing the sliding door 11 from moving upward on the door tip side. For this reason, unless it is just before the sliding door 11 closes, a jumping-up prevention function cannot be exhibited.

引き戸装置の使用環境によっては、引き戸１１が閉まる直前よりも早期に制動装置による制動力を作用させることにより、できるだけ時間をかけてゆっくりと引き戸１１を停止させることが要求される場合がある。特許文献２に記載された跳ね上がり防止装置によってこの要求を満たすためには、上側部材３１の取り付け位置を上側レール１２の終端位置よりも手前（図１３では左側）の位置に変更して制動が開始されるタイミングを早める必要がある。 Depending on the usage environment of the sliding door device, it may be required to stop the sliding door 11 slowly over as much time as possible by applying the braking force by the braking device earlier than immediately before the sliding door 11 is closed. In order to satisfy this requirement by the jump-up preventing device described in Patent Document 2, the mounting position of the upper member 31 is changed to a position closer to the front side (left side in FIG. 13) than the terminal position of the upper rail 12, and braking is started. It is necessary to advance the timing.

しかし、引き戸１１には上側レール１２に係合しつつ案内されるガイド部材１３Ａが上方に突き出して設けられているため、上側部材３１の取り付け位置はガイド部材１３Ａと干渉しない位置に制限される。このため、ガイド部材１３Ａが引き戸１１の戸先近くに設けられている場合においては、上側部材３１を上側レール１２の終端位置に取り付けざるを得ず、上記要求を満たすことはできない。 However, since the sliding door 11 is provided with a guide member 13A that is guided while being engaged with the upper rail 12, the attachment position of the upper member 31 is limited to a position that does not interfere with the guide member 13A. For this reason, when the guide member 13 A is provided near the door end of the sliding door 11, the upper member 31 must be attached to the terminal position of the upper rail 12, and the above requirement cannot be satisfied.

本発明が解決しようとする課題は、引き戸を閉まり際に制動してゆっくりと停止させる制動機構を備えた引き戸装置において、引き戸の跳ね上がりを制動機構による制動が開始されるタイミングに合わせて確実に防止することができる跳ね上がり防止装置を提供することにある。 The problem to be solved by the present invention is that in a sliding door device provided with a braking mechanism that brakes and slowly stops when the sliding door is closed, the sliding door is reliably prevented from jumping up in accordance with the timing when the braking by the braking mechanism is started. An object of the present invention is to provide an anti-bounce device that can be used.

上記課題を解決するために、本発明の跳ね上がり防止装置は、建物の開口部を開閉する引き戸と、前記開口部の上端に設けられたガイドレールと、前記引き戸の戸先側上端部に固定され前記ガイドレールに案内されつつ前記引き戸と共にスライドするガイド部材と、前記引き戸を閉まり際に制動する制動機構と、を備えた引き戸装置における前記引き戸の制動時の跳ね上がりを防止する装置であって、前記ガイドレールに取り付けられた本体と、前記引き戸の制動時に前記引き戸の上端面に当接して前記引き戸の戸先側の上方への移動を阻止する跳ね上がり防止部材と、前記跳ね上がり防止部材を保持しつつ前記引き戸の開閉方向にスライド可能に前記本体に支持されたスライド部材と、前記引き戸が閉じ側に移動する際、前記跳ね上がり防止部材の下端面と前記引き戸の上端面とが向かい合った後の所定のタイミングで前記スライド部材と前記ガイド部材とを連結する連結機構と、を有することを特徴としている。 In order to solve the above-mentioned problems, a splash prevention device according to the present invention is fixed to a sliding door that opens and closes an opening of a building, a guide rail provided at an upper end of the opening, and an upper end of the sliding door. A device for preventing a jumping-up at the time of braking of the sliding door in a sliding door device comprising: a guide member that slides with the sliding door while being guided by the guide rail; and a braking mechanism that brakes when the sliding door is closed, While holding the main body attached to the guide rail, the spring-up preventing member that abuts on the upper end surface of the sliding door when the sliding door is braked and prevents the sliding door from moving upward on the door tip side, and holding the spring-up preventing member A sliding member supported by the main body so as to be slidable in the opening / closing direction of the sliding door, and when the sliding door moves to the closing side, the splash prevention Is characterized by having a connecting mechanism for connecting the guide member and the slide member at a predetermined timing after which the lower surface and the upper end surface of the sliding door facing the member.

この構成によれば、引き戸が閉位置側に移動する際、跳ね上がり防止部材の下端面と引き戸の上端面とが向かい合った後の所定のタイミングでスライド部材と引き戸のガイド部材とが連結される。その後、引き戸が閉止状態になるまで、スライド部材とこれに保持されている跳ね上がり防止部材とが引き戸のガイド部材と共に移動する。
したがって、跳ね上がり防止部材をガイドレールの終端位置よりも可成り手前の位置に待機させた場合でも、その跳ね上がり防止部材が引き戸のガイド部材と干渉することはなく、引き戸の跳ね上がりを制動機構による制動が開始されるタイミングに合わせて確実に防止することができる。 According to this structure, when the sliding door moves to the closed position side, the slide member and the guide member of the sliding door are connected at a predetermined timing after the lower end surface of the spring-up preventing member and the upper end surface of the sliding door face each other. Thereafter, the sliding member and the spring-up preventing member held by the sliding member move together with the sliding door guide member until the sliding door is closed.
Therefore, even when the bounce prevention member is made to stand by at a position substantially before the end position of the guide rail, the bounce prevention member does not interfere with the guide member of the sliding door, and the sliding mechanism prevents the sliding door from jumping up. This can be surely prevented in accordance with the start timing.

前記連結機構は、前記スライド部材に支持され、且つ前記ガイド部材の上端部に係脱自在に連結されるラッチ部材と、前記ラッチ部材を前記ガイド部材との連結を解除する向きに常時付勢している付勢部材と、前記所定のタイミングで前記ラッチ部材を前記付勢部材による付勢力に抗しつつ前記ガイド部材に連結するラッチ作動機構と、を有することが望ましい。
この構成によれば、ラッチ部材を付勢部材による付勢力によって待機姿勢にしておき、跳ね上がり防止部材の下端面と引き戸の上端面とが向かい合った後の所定のタイミングでラッチ部材をガイド部材に連結して、ガイド部材とスライド部材とを相互に連結することができる。 The connection mechanism is supported by the slide member and is detachably connected to an upper end portion of the guide member, and constantly urges the latch member in a direction to release the connection with the guide member. It is desirable to have an urging member that is connected to the guide member while resisting the urging force of the urging member at the predetermined timing.
According to this configuration, the latch member is placed in the standby posture by the urging force of the urging member, and the latch member is connected to the guide member at a predetermined timing after the lower end surface of the splash prevention member and the upper end surface of the sliding door face each other. Thus, the guide member and the slide member can be connected to each other.

また、前記ラッチ部材の先端部（引き戸の開位置側の端部）の下部には、前記ガイド部材を前記ラッチ部材の下に入り込ませるべく傾斜したガイド面が設けられていることが望ましい。
この構成によれば、先端側ガイド部材に連結されていないにもかかわらず、何らかの原因でラッチ部材が先端側ガイド部材との連結姿勢（異常姿勢）になっている場合でも、引き戸を閉位置側に移動させることにより、先端側ガイド部材をラッチ部材の下に入り込ませて、ラッチ部材を正常姿勢に復帰させることができる。 Moreover, it is preferable that a guide surface that is inclined so as to allow the guide member to enter under the latch member is provided at a lower portion of the front end portion of the latch member (end portion on the opening position side of the sliding door).
According to this configuration, even when the latch member is in a connected posture (abnormal posture) with the distal-side guide member for some reason even though it is not coupled to the distal-side guide member, the sliding door is closed to the closed position side. By moving the leading end side guide member into the normal position, the leading end side guide member can enter under the latch member.

本発明の引き戸の跳ね上がり防止装置は、更に、前記引き戸の開位置側への移動に連動させて前記ガイド部材と前記ラッチ部材との連結を解除する連結解除機構を有することが望ましい。
この構成によれば、ガイド部材とスライド部材とが連結された状態から、引き戸を開位置側へ移動させることにより、ガイド部材とラッチ部材との連結を自動的に解除することができる。 The sliding door splash prevention device of the present invention preferably further includes a connection release mechanism that releases the connection between the guide member and the latch member in conjunction with the movement of the sliding door toward the open position.
According to this configuration, the connection between the guide member and the latch member can be automatically released by moving the sliding door to the open position side from the state where the guide member and the slide member are connected.

本発明の引き戸の跳ね上がり防止装置は、更に、前記スライド部材による前記跳ね上がり防止部材の上下方向の保持位置を調節するための調節機構を有することが望ましい。
この構成によれば、引き戸の制動時に跳ね上がり防止部材の下端面が引き戸の上端面に確実に当接するように、跳ね上がり防止部材の上下方向の保持位置を調節することができる。 It is preferable that the sliding door splash preventing device of the present invention further includes an adjustment mechanism for adjusting the vertical holding position of the splash preventing member by the slide member.
According to this configuration, the vertical holding position of the spring-up preventing member can be adjusted so that the lower end surface of the spring-up preventing member reliably contacts the upper end surface of the sliding door when the sliding door is braked.

本発明の引き戸の跳ね上がり防止装置によれば、引き戸の跳ね上がりを制動機構による制動が開始されるタイミングに合わせて確実に防止することができる。 According to the sliding door splash prevention device of the present invention, it is possible to reliably prevent the sliding door from jumping up in accordance with the timing at which braking by the braking mechanism is started.

The guide members 13A and 13B have a columnar shaft portion 13a protruding upward from the upper end surface of the sliding door 11, and a circular head portion 13b provided at the upper end of the shaft portion 13a. By sliding the head portions 13b of the guide members 13A and 13B in contact with the inner edge of the guide slit 12a, the sliding door 11 can be smoothly opened and closed with little backlash.

ガイド部材１３Ａ、１３Ｂは、引き戸１１の上端の開閉方向両端近傍に設けられている。以下、引き戸１１の閉まる側に設けられたガイド部材１３Ａを先端側ガイド部材１３Ａと、開く側に設けられたガイド部材１３Ｂを後端側ガイド部材１３Ｂと、それぞれ記す。 The guide members 13 A and 13 B are provided near both ends in the opening / closing direction of the upper end of the sliding door 11. Hereinafter, the guide member 13A provided on the side where the sliding door 11 is closed is referred to as a front end side guide member 13A, and the guide member 13B provided on the side to be opened is referred to as a rear end side guide member 13B.

制動機構１４は、引き戸１１の閉まり際に後端側ガイド部材１３Ｂを捕捉して引き戸１１に制動力を作用させる機構である。制動機構１４は、ガイドレール１２内の所定の位置に設置されている。 The braking mechanism 14 is a mechanism that captures the rear end side guide member 13 B when the sliding door 11 is closed and applies a braking force to the sliding door 11. The braking mechanism 14 is installed at a predetermined position in the guide rail 12.

跳ね上がり防止装置１５は、ガイドレール１２内の戸先側端部（図示右側端部）に設置されている。
図３乃至図１１に示すように、跳ね上がり防止装置１５は、本体１６と、跳ね上がり防止部材１７と、スライド部材１８と、連結機構１９と、連結解除機構２５とを備えている。 The splash prevention device 15 is installed at the door end side end portion (the right end portion in the figure) in the guide rail 12.
As shown in FIGS. 3 to 11, the splash prevention device 15 includes a main body 16, a splash prevention member 17, a slide member 18, a coupling mechanism 19, and a coupling release mechanism 25.

本体１６は、ガイドレール１２内に嵌合させて、ガイドレール１２の上部に螺子２０で締着固定されている。本体１６内には、スライド部材１８及び連結機構１９がスライド自在に収容されている。 The main body 16 is fitted into the guide rail 12 and fastened and fixed to the upper portion of the guide rail 12 with a screw 20. A slide member 18 and a connecting mechanism 19 are slidably accommodated in the main body 16.

跳ね上がり防止部材１７は、引き戸１１の制動時に引き戸１１の上端面１１ａに当接して引き戸１１の戸先側の上方への移動を阻止する部材である。この例では、跳ね上がり防止部材１７として、螺子部１７ａと円板状のヘッド部１７ｂとを有するボルトが使用されている。ヘッド部１７ｂの下面１７ｃの中央部には、プラスドライバ等の工具を使用して跳ね上がり防止部材１７を回動操作するための十字穴１７ｄが形成されている。 The spring-up preventing member 17 is a member that abuts on the upper end surface 11a of the sliding door 11 during braking of the sliding door 11 and prevents the sliding door 11 from moving upward on the door tip side. In this example, a bolt having a screw portion 17a and a disk-shaped head portion 17b is used as the spring-up preventing member 17. A cross hole 17d is formed in the center of the lower surface 17c of the head portion 17b for turning the splash preventing member 17 using a tool such as a Phillips screwdriver.

スライド部材１８には、跳ね上がり防止部材１７を保持するための螺子孔１８ａが設けられている。螺子孔１８ａには跳ね上がり防止部材１７の螺子部１７ａが螺合しており、プラスドライバ等の工具を使用して跳ね上がり防止部材１７を回動操作することにより、スライド部材１８による跳ね上がり防止部材１７の上下方向の保持位置を調節することができるようになっている。すなわち、この例では、跳ね上がり防止部材１７に設けられた螺子部１７ａとスライド部材１８に設けられた螺子孔１８ａとにより跳ね上がり防止部材１７の高さ位置調節機構２１が構成されている。 The slide member 18 is provided with a screw hole 18 a for holding the spring-up preventing member 17. The screw portion 17a of the bounce prevention member 17 is screwed into the screw hole 18a, and the bounce prevention member 17 by the slide member 18 is rotated by rotating the bounce prevention member 17 using a tool such as a Phillips screwdriver. The holding position in the vertical direction can be adjusted. That is, in this example, the height position adjusting mechanism 21 of the spring-up preventing member 17 is configured by the screw portion 17 a provided in the spring-up preventing member 17 and the screw hole 18 a provided in the slide member 18.

スライド部材１８は、本体１６の内面に嵌合した状態で本体１６の長手方向にスライドする。本体１６の両側壁には、スライド部材１８を案内するガイドスリット１６ａが設けられている。スライド部材１８の両側部には、ガイドスリット１６ａに嵌合しつつ案内される横長のガイド突起１８ｂが設けられている。ガイド突起１８ｂを横長にすることにより、スライド部材１８のガイド方向のがたつきを防止している。 The slide member 18 slides in the longitudinal direction of the main body 16 while being fitted to the inner surface of the main body 16. Guide slits 16 a for guiding the slide member 18 are provided on both side walls of the main body 16. On both sides of the slide member 18, horizontally long guide projections 18b are provided that are guided while being fitted into the guide slits 16a. By making the guide protrusion 18b horizontally long, the guide member 18 is prevented from rattling in the guide direction.

連結機構１９は、ラッチ部材２２と、付勢部材２３と、ラッチ作動機構２４と、連結解除機構２５と、を有している。
ラッチ部材２２は、スライド部材１８と先端側ガイド部材１３Ａとを連結するための部材である。ラッチ部材２２は、スライド部材１８に上下に回動自在に支持されており、それ自体が上下に回動することによって先端側ガイド部材１３Ａの上端部に係脱するように構成されている。
スライド部材１８の後端部（引き戸１１の開位置側の端部）には、ラッチ部材２２をスライド部材１８に上下に回動自在に支持するための支持孔１８ｃを有するブラケット部１８ｄが形成されている。ラッチ部材２２の基端部（引き戸１１の閉位置側の端部）の上隅部には両支持孔１８ｃに回動自在に嵌合する軸状突起部２２ａが設けられている。ラッチ部材２２は、その軸状突起部２２ａがブラケット部１８ｄの支持孔１８ｃに連結されることにより、スライド部材１８に上下に回動自在に連結されている。 The connection mechanism 19 includes a latch member 22, an urging member 23, a latch operation mechanism 24, and a connection release mechanism 25.
The latch member 22 is a member for connecting the slide member 18 and the distal end side guide member 13A. The latch member 22 is supported by the slide member 18 so as to be pivotable up and down, and is configured to engage with and disengage from the upper end portion of the distal end side guide member 13A by pivoting itself up and down.
A bracket portion 18d having a support hole 18c for pivotally supporting the latch member 22 up and down on the slide member 18 is formed at the rear end portion of the slide member 18 (the end portion on the opening position side of the sliding door 11). ing. A shaft-like protrusion 22a is provided at the upper corner of the base end of the latch member 22 (the end on the closed position side of the sliding door 11). The latch member 22 is connected to the slide member 18 so that the shaft-like protrusion 22a is connected to the support hole 18c of the bracket 18d so that the latch member 22 can turn up and down.

付勢部材２３は、ラッチ部材２２とスライド部材１８との間に設けられている。この例では、付勢部材２３としてコイルばねが用いられている。ラッチ部材２２とスライド部材１８の互いの対面部には、付勢部材２３の端部を受け入れて保持する保持穴２２ｄ、１８ｅがそれぞれ形成されている。付勢部材２３は、ラッチ部材２２を上方に回動させる向き、すなわち先端側ガイド部材１３Ａとの連結を解除する向きに常時付勢している。 The urging member 23 is provided between the latch member 22 and the slide member 18. In this example, a coil spring is used as the urging member 23. Holding holes 22d and 18e for receiving and holding the end portion of the urging member 23 are formed in the facing portions of the latch member 22 and the slide member 18, respectively. The urging member 23 is always urged in a direction in which the latch member 22 is rotated upward, that is, in a direction in which the connection with the distal end side guide member 13A is released.

ラッチ部材２２の下部には、先端側ガイド部材１３Ａのヘッド部１３ｂに嵌合する嵌合凹部２２ｂが設けられている。ラッチ部材２２の基端部の下部には、引き戸１１が閉まる際、先端側ガイド部材１３Ａのヘッド部１３ｂが当接するガイド当接部２２ｅが設けられている。ガイド当接部２２ｅは、嵌合凹部２２ｂの基端側の壁を構成している。
ラッチ部材２２は、引き戸１１が閉位置側に移動する際、そのガイド当接部２２ｅが先端側ガイド部材１３Ａに押されることにより、付勢部材２３による付勢力に抗して下方に回動させられる。そして、跳ね上がり防止部材１７の下端面１７ｃと引き戸１１の上端面１１ａとが向かい合った後の所定のタイミングで先端側ガイド部材１３Ａに連結される（図８及び図９参照）。すなわち、この例では、ガイド当接部２２ｅを有するラッチ部材２２自体がラッチ作動機構２４を構成している。ラッチ部材２２の先端部（引き戸１１の開位置側の端部）の下部には、嵌合凹部２２ｂからラッチ部材２２の先端に向かって上方に傾斜したガイド面２２ｃが設けられている。 A fitting recess 22b that fits into the head portion 13b of the distal end side guide member 13A is provided at the lower portion of the latch member 22. A guide abutting portion 22e with which the head portion 13b of the distal end side guide member 13A abuts when the sliding door 11 is closed is provided below the base end portion of the latch member 22. The guide contact portion 22e constitutes a wall on the proximal end side of the fitting recess 22b.
When the sliding door 11 moves to the closed position side, the latch member 22 is rotated downward against the urging force of the urging member 23 by the guide contact portion 22e being pushed by the distal end side guide member 13A. It is done. And it connects with 13 A of front end side guide members at the predetermined timing after the lower end surface 17c of the splash prevention member 17 and the upper end surface 11a of the sliding door 11 face each other (refer FIG.8 and FIG.9). That is, in this example, the latch member 22 itself having the guide contact portion 22 e constitutes the latch operation mechanism 24. A guide surface 22 c that is inclined upward from the fitting recess 22 b toward the tip of the latch member 22 is provided at the lower portion of the tip of the latch member 22 (the end on the opening position side of the sliding door 11).

連結解除機構２５は、付勢部材２３と、ラッチ部材２２の先端部両側に設けられたガイド突起２２ｆと、本体１６の両内側面に設けられたガイド段部１６ｂとで構成される。ガイド突起２２ｆは、付勢部材２３による付勢力でガイド段部１６ｂに押しつけられ、ガイド段部１６ｂに倣いつつ移動する。ガイド段部１６ｂは、ガイド突起２２ｆを水平方向に案内する水平部１６ｂ1と、水平部１６ｂ1の終端（引き戸１１の開位置側の端）から上方に斜めに延びる傾斜部１６ｂ2とからなる。ラッチ部材２２が先端側ガイド部材１３Ａに連結された状態で引き戸１１が開位置側に移動する際、ガイド突起２２ｆが水平部１６ｂ1から傾斜部１６ｂ2に移動することにより、ラッチ部材２２が付勢部材２３による付勢力により上方に回動し、先端側ガイド部材１３Ａとラッチ部材２２との連結が解除される仕組みになっている。 The connection release mechanism 25 includes an urging member 23, guide protrusions 22 f provided on both sides of the distal end portion of the latch member 22, and guide step portions 16 b provided on both inner side surfaces of the main body 16. The guide protrusion 22f is pressed against the guide step portion 16b by the urging force of the urging member 23, and moves while following the guide step portion 16b. The guide step portion 16b includes a horizontal portion 16b1 for guiding the guide protrusion 22f in the horizontal direction, and an inclined portion 16b2 extending obliquely upward from the end of the horizontal portion 16b1 (the end on the opening position side of the sliding door 11). When the sliding door 11 moves to the open position side with the latch member 22 connected to the distal end side guide member 13A, the guide protrusion 22f moves from the horizontal portion 16b1 to the inclined portion 16b2, thereby causing the latch member 22 to be a biasing member. The mechanism is pivoted upward by the urging force of 23, and the connection between the distal end side guide member 13A and the latch member 22 is released.

つぎに、上記のように構成された跳ね上がり防止装置１５の作用・効果について説明する。
引き戸１１が閉位置側に移動する際、跳ね上がり防止部材１７の下端面１７ｃと引き戸１１の上端面１１ａとが向かい合った後の所定のタイミングでスライド部材１８と引き戸１１の先端側ガイド部材１３Ａとが連結される。その後、引き戸１１が閉止状態になるまで、スライド部材１８とこれに保持されている跳ね上がり防止部材１７とが引き戸１１のガイド部材１３と共に移動する。このため、跳ね上がり防止部材１７をガイドレール１２の終端位置よりも可成り手前の位置に待機させても、跳ね上がり防止部材１７が引き戸１１の先端側ガイド部材１３Ａと干渉しない。
したがって、引き戸１１が閉まる際、完全に閉まるタイミングよりも可成り早期に制動機構１４を働かせてゆっくりと時間をかけて引き戸１１を停止させるように構成された引き戸装置１０においても、引き戸１１の跳ね上がりを制動機構１４による制動が開始されるタイミングに合わせて確実に防止することができる。 Next, the operation and effect of the splash prevention device 15 configured as described above will be described.
When the sliding door 11 moves to the closed position side, the slide member 18 and the leading end side guide member 13A of the sliding door 11 are moved at a predetermined timing after the lower end surface 17c of the splash prevention member 17 and the upper end surface 11a of the sliding door 11 face each other. Connected. Thereafter, the sliding member 18 and the spring-up preventing member 17 held by the sliding member 18 move together with the guide member 13 of the sliding door 11 until the sliding door 11 is closed. For this reason, even if the bounce prevention member 17 is made to stand by at a position considerably before the end position of the guide rail 12, the bounce prevention member 17 does not interfere with the front end side guide member 13A of the sliding door 11.
Therefore, when the sliding door 11 is closed, even in the sliding door apparatus 10 configured to stop the sliding door 11 over time by operating the braking mechanism 14 considerably earlier than the timing when the sliding door 11 is completely closed, the sliding door 11 jumps up. Can be reliably prevented in accordance with the timing at which braking by the braking mechanism 14 is started.

また、先端側ガイド部材１３Ａとスライド部材１８とが連結された状態から、引き戸１１を開位置側へ移動させたときに、先端側ガイド部材１３Ａとスライド部材１８との連結が自動的に解除される仕組みになっているので、この跳ね上がり防止装置１５を設けたことで引き戸１１の使い勝手が損なわれることはない。 Further, when the sliding door 11 is moved to the open position side from the state where the distal end side guide member 13A and the slide member 18 are coupled, the coupling between the distal end side guide member 13A and the slide member 18 is automatically released. Therefore, the usability of the sliding door 11 is not impaired by the provision of the spring-up preventing device 15.

また、この跳ね上がり防止装置１５は、プラスドライバ等の工具を使用して跳ね上がり防止部材１７を回動操作することにより、跳ね上がり防止部材１７の下面１７ｃが引き戸１１の上端面１１ａに確実に当接するように、跳ね上がり防止部材１７の上下方向の保持位置を容易に調節することができるので、ガイドレール１２と引き戸１１との間隔等が異なる種々の引き戸装置に適用可能である。例えば、図１０に示すように、跳ね上がり防止部材１７と引き戸１１とが離れている場合、跳ね上がり防止装置１５の跳ね上がり防止機能を有効に働かせることはできないが、図１１に示すように、跳ね上がり防止部材１７の下面１７ｃが引き戸１１の上端面１１ａに当接するように跳ね上がり防止部材１７の上下方向の位置を調節しておくことにより、跳ね上がり防止機能を有効に働かせることができるようになる。 Further, the bounce prevention device 15 rotates the bounce prevention member 17 using a tool such as a Phillips screwdriver so that the lower surface 17c of the bounce prevention member 17 is surely brought into contact with the upper end surface 11a of the sliding door 11. In addition, since the vertical holding position of the splash preventing member 17 can be easily adjusted, the present invention can be applied to various sliding door devices in which the distance between the guide rail 12 and the sliding door 11 is different. For example, as shown in FIG. 10, when the bounce prevention member 17 and the sliding door 11 are separated from each other, the bounce prevention function of the bounce prevention device 15 cannot be used effectively, but as shown in FIG. 11, the bounce prevention member By adjusting the vertical position of the spring-up preventing member 17 so that the lower surface 17c of the door 17 is in contact with the upper end surface 11a of the sliding door 11, the spring-up preventing function can be effectively operated.

また、ラッチ部材２２の先端部下部にガイド面２２ｃが設けられているので、先端側ガイド部材１３Ａに連結されていないにもかかわらず、何らかの原因でラッチ部材２２が先端側ガイド部材１３Ａとの連結姿勢すなわち、下方に回動したままの異常姿勢になっている場合でも、引き戸１１を閉位置側に移動させることにより、先端側ガイド部材１３Ａをラッチ部材２２の下に入り込ませて、ラッチ部材２２を正常姿勢に復帰させることができる。 Further, since the guide surface 22c is provided at the lower end of the leading end portion of the latch member 22, the latch member 22 is connected to the leading end side guide member 13A for some reason even though it is not coupled to the leading end side guide member 13A. Even if the posture, that is, the abnormal posture while rotating downward, is moved to the closed position side by moving the sliding door 11, the tip side guide member 13 A enters under the latch member 22, and the latch member 22. Can be returned to a normal posture.

なお、上記実施形態では、本発明の跳ね上がり防止装置を下荷重タイプの引き戸装置に適用した例を示したが、上荷重タイプの引き戸装置にも適用可能である。
また、上記実施形態では、ラッチ部材２２がスライド部材１８に上下に回動自在に支持されているが、ラッチ部材２２がスライド部材１８に上下に移動自在（昇降自在）に支持されている構成を採用してもよい。
また、上記実施形態では、付勢部材２３としてコイルばねが用いられているが、コイルばねに代えて板ばねを用いてもよい。また、スライド部材１８またはラッチ部材２２に、板ばねとして機能する弾性部を一体形成により設けてもよい。また、ばねに代えてゴムやダンパ機構を用いてもよい。
また、上記実施形態では、スライド部材１８とラッチ部材２２がそれぞれ別々の部材であるが、両部材１８、２２を樹脂などで一体として成型し、スライド部に対してラッチ部が弾性的に上下に揺動する構成を採用してもよい。この場合、スライド部とラッチ部との間の樹脂弾性を利用することにより、付勢部材２３を省略することも可能である。 In addition, although the example which applied the splash prevention apparatus of this invention to the lower load type sliding door apparatus was shown in the said embodiment, it is applicable also to an upper load type sliding door apparatus.
Moreover, in the said embodiment, although the latch member 22 is supported by the slide member 18 so that rotation up and down is possible, the latch member 22 is supported by the slide member 18 so that it can move up and down (movable up and down). It may be adopted.
Moreover, in the said embodiment, although the coil spring is used as the biasing member 23, it may replace with a coil spring and may use a leaf | plate spring. Further, the slide member 18 or the latch member 22 may be provided with an elastic portion that functions as a leaf spring by being integrally formed. Further, instead of the spring, rubber or a damper mechanism may be used.
In the above-described embodiment, the slide member 18 and the latch member 22 are separate members. However, the members 18 and 22 are molded integrally with resin, and the latch portion is elastically moved up and down with respect to the slide portion. A swinging configuration may be employed. In this case, the biasing member 23 can be omitted by utilizing the resin elasticity between the slide portion and the latch portion.
