Description

本発明は、戸車を備えた引戸に関するものである。 The present invention relates to a sliding door provided with a door cart.

引戸の開閉を容易にするために、従来から引戸に戸車を設けることが多い。従来の戸車としては、例えば特許文献１に開示されているようなものがある。特許文献１に開示されている吊戸車には、引戸の脱着を容易に行うための工夫がなされている。
特開平１０−２３８２０７号公報 In order to easily open and close the sliding door, a sliding door is often provided in the sliding door. As a conventional door cart, there exists a thing as disclosed by patent document 1, for example. The hanging door car disclosed in Patent Document 1 is devised for easily removing and attaching the sliding door.
Japanese Patent Laid-Open No. 10-238207

特許文献１の戸車を図９に示す。特許文献１の戸車は、建物躯体９０に設置された上レール９５と係合する吊戸車９１と、引戸８０に装着される吊具本体９２とを備えている。吊戸車９１には、下方に延びる軸の下端に拡径部９４が設けてあり、吊具本体９２には、復元力を有するクリップ９５で間隔を一定に保持されるスリット９３が設けてある。
拡径部９４が、このスリット９３を押し広げながら通過すると、スリット９３はクリップ９５の弾性力によって元の間隔に戻り、拡径部９４はスリット９３内を逆行することができず、拡径部９４は吊具本体９２の下端に当接して、吊戸車９１は引戸８０を支持する。このように、特許文献１には、引戸８０をワンタッチで戸車に装着することができる構成が開示されている。 FIG. 9 shows a door cart of Patent Document 1. The door cart of Patent Document 1 includes a suspension door wheel 91 that engages with an upper rail 95 installed in a building housing 90, and a suspension body 92 that is attached to the sliding door 80. The suspension door 91 is provided with an enlarged diameter portion 94 at the lower end of a shaft extending downward, and the suspension body 92 is provided with a slit 93 that is held at a constant interval by a clip 95 having a restoring force.
When the enlarged diameter portion 94 passes through the slit 93 while expanding the slit 93, the slit 93 returns to the original interval due to the elastic force of the clip 95, and the enlarged diameter portion 94 cannot reverse in the slit 93. 94 abuts on the lower end of the hanging tool main body 92, and the suspended door wheel 91 supports the sliding door 80. As described above, Patent Document 1 discloses a configuration in which the sliding door 80 can be attached to the door cart with one touch.

しかし、このような構造では、吊戸車９１から引戸８０を外す際には、例えば特許文献１に開示されている楔９６をスリット９３に差し込まなければならず、また、スリット９３の間隔が拡がらないようにするためのロック機構がないため安全性に欠ける。 However, in such a structure, when removing the sliding door 80 from the suspension door wheel 91, for example, the wedge 96 disclosed in Patent Document 1 must be inserted into the slit 93, and the interval between the slits 93 is increased. It lacks safety because there is no locking mechanism to prevent it.

また、特許文献１に開示されている構成では、楔９６を差し込むための空間を確保する必要があるので、上レール９０と引戸８０をある程度離しておかなければならない。そのため、引戸の設置空間に制約ができ、設置が困難な場合が多くなる。 Further, in the configuration disclosed in Patent Document 1, since it is necessary to secure a space for inserting the wedge 96, the upper rail 90 and the sliding door 80 must be separated to some extent. For this reason, the installation space of the sliding door can be restricted, and the installation is often difficult.

そこで本発明は、戸車への引戸の着脱を確実に行うことができ、また、戸車に引戸を装着した際に、引戸が脱落しないようにするロック機構を備え、安全性に配慮した戸車を備えた引戸を提供することを課題としている。 Therefore, the present invention can securely attach and detach the sliding door to and from the door pulley, and also includes a lock mechanism that prevents the sliding door from falling off when the sliding door is attached to the door wheel, and includes a door door that takes safety into consideration. The challenge is to provide a sliding door.

図１は、本発明の引戸２０に備えた戸車１の斜視図であり、図２は、戸車１の分解斜視図である。図１に示すように戸車１は、レール係合部材２とスライド部材３とで構成されている。この戸車１が、引戸２０に設置された連結部材１９と連結され、引戸２０がレール５０に設置される。以下、戸車１の構造を、レール係合部材２とスライド部材３に分けて、図２〜図４を参照しながら説明し、続いて連結部材１９の構造を説明し、最後に戸車１と連結部材１９の連結構造について説明する。 FIG. 1 is a perspective view of a door wheel 1 provided in the sliding door 20 of the present invention, and FIG. 2 is an exploded perspective view of the door wheel 1. As shown in FIG. 1, the door pulley 1 includes a rail engaging member 2 and a slide member 3. The door 1 is connected to a connecting member 19 installed on the sliding door 20, and the sliding door 20 is installed on the rail 50. Hereinafter, the structure of the door pulley 1 is divided into the rail engaging member 2 and the slide member 3 and will be described with reference to FIGS. 2 to 4, followed by the structure of the connecting member 19, and finally connected to the door wheel 1. The connection structure of the member 19 will be described.

まず、レール係合部材２について説明する。図３（ａ）及び図３（ｂ）は、それぞれレール係合部材２の平面図及び正面図である。図３（ａ）及び図３（ｂ）に示すようにレール係合部材２は、底壁９と、底壁９の周囲に起立する側壁２ａとで構成されている。底壁９と側壁２ａによって、上方と右方が開放された内部空間６が形成されている。 First, the rail engaging member 2 will be described. 3A and 3B are a plan view and a front view of the rail engaging member 2, respectively. As shown in FIGS. 3A and 3B, the rail engaging member 2 includes a bottom wall 9 and a side wall 2 a that stands around the bottom wall 9. The bottom wall 9 and the side wall 2a form an internal space 6 that opens upward and to the right.

レール係合部材２は、矢印Ａで示す戸車１の移動方向に細長く、中央部１７が両端部１５、１６よりも幅が広くなっている。両端部１５、１６の側壁２ａには、後述する軸４を貫通させることができるように、孔５が設けてある。すなわち、二つの孔５が一対となって、同一の軸４を貫通させ、レール係合部材２の両端部にそれぞれ軸４を貫通させることができるようになっている。また、中央部１７の底面９の幅方向の中央には、後述する連結部材１９のフランジ部を貫通させる貫通孔１０が設けてある。 The rail engaging member 2 is elongated in the moving direction of the door wheel 1 indicated by the arrow A, and the central portion 17 is wider than both end portions 15 and 16. Holes 5 are provided in the side walls 2a of both end portions 15 and 16 so that a shaft 4 described later can be passed therethrough. That is, the two holes 5 are paired so as to penetrate the same shaft 4 and allow the shaft 4 to penetrate the both ends of the rail engaging member 2. A through hole 10 is provided in the center of the bottom surface 9 of the center portion 17 in the width direction so as to pass through a flange portion of a connecting member 19 described later.

図２、図３（ａ）、図３（ｂ）に示すように、レール係合部材２の底壁９の下面には、ガイド部材１８が設けてある。ガイド部材１８は、連結部材１９のロッド２１を、貫通孔１０に導く役割を果たす。また、図３（ａ）、図３（ｂ）に示すように、レール係合部材２の端部１６には、底壁９の端部である段２３（突起係合部）が設けてある。この段２３は、後述するスライド部材３の突起２４と係合する。
以降の説明の都合上、図３（ａ）に示すように、中央部１７の矢印Ａ（戸車１の移動方向）の長さをＬ１とし、幅をＷ１とする。 As shown in FIGS. 2, 3 (a), and 3 (b), a guide member 18 is provided on the lower surface of the bottom wall 9 of the rail engaging member 2. The guide member 18 plays a role of guiding the rod 21 of the connecting member 19 to the through hole 10. Further, as shown in FIGS. 3A and 3B, the end portion 16 of the rail engagement member 2 is provided with a step 23 (projection engagement portion) that is an end portion of the bottom wall 9. . This step 23 is engaged with a protrusion 24 of the slide member 3 described later.
For convenience of the following description, as shown in FIG. 3A, the length of the arrow A (the moving direction of the door cart 1) of the central portion 17 is L1, and the width is W1.

次に、スライド部材３について説明する。図４（ａ）及び図４（ｂ）は、それぞれスライド部材３の平面図及び正面図である。スライド部材３は、レール係合部材２の両端部１５、１６及び中央部１７に対応する両端部１１、１２及び中央部１３を備えている。 Next, the slide member 3 will be described. 4A and 4B are a plan view and a front view of the slide member 3, respectively. The slide member 3 includes both end portions 11 and 12 and a center portion 13 corresponding to the both end portions 15 and 16 and the center portion 17 of the rail engaging member 2.

中央部１３の幅Ｗ２は、レール係合部材２の中央部１７（内部空間６）にちょうど収容可能な寸法に設定されている。すなわち、中央部１３の幅Ｗ２は、レール係合部材２の中央部１７の幅Ｗ１よりも若干小さい。両端部１１、１２の幅は、レール係合部材２の両端部１５、１６（内部空間６）に収容可能な寸法に設定されている。 The width W 2 of the central portion 13 is set to a dimension that can be accommodated in the central portion 17 (internal space 6) of the rail engaging member 2. That is, the width W 2 of the central portion 13 is slightly smaller than the width W 1 of the central portion 17 of the rail engaging member 2. The widths of both end portions 11 and 12 are set to dimensions that can be accommodated in both end portions 15 and 16 (internal space 6) of the rail engaging member 2.

また、中央部１３の長さＬ２は、レール係合部材２の中央部１７の内部空間６の長さＬ１よりも短く設定されており、スライド部材３は、レール係合部材２に対して、Ｌ１とＬ２の差の範囲内でスライド移動することができるようになっている。 The length L2 of the central portion 13 is set to be shorter than the length L1 of the internal space 6 of the central portion 17 of the rail engaging member 2, and the slide member 3 is The sliding movement is possible within the range of the difference between L1 and L2.

図４（ａ）に示すように、スライド部材３の中央部１３には、小径部１４ａと大径部１４ｂとが連続する孔１４が設けてある。孔１４は、スライド部材３の幅方向の中央に配置されている。また、スライド部材３の端部１１及び１２には、それぞれ長孔１１ａ、１２ａが設けてある。軸４（図２）は、長孔１１ａ、１２ａを貫通する。すなわち、一つの軸４は、レール係合部材２の端部１５に設けた一対の孔５と、スライド部材３の端部１１に設けた長孔１１ａとを貫通する。さらに軸４は、図２に示すように端部１５の両側に配置された二つのローラ７の貫通孔７ａを貫通し、軸４の両端に設けた内ねじ４ａに、ねじ８を螺合させてローラ７がレール係合部材２に回転可能に装着される。端部１６側にも、端部１５側と同様に、別の軸４によって、ローラ７が装着される。 As shown in FIG. 4A, the central portion 13 of the slide member 3 is provided with a hole 14 in which a small diameter portion 14a and a large diameter portion 14b are continuous. The hole 14 is disposed at the center in the width direction of the slide member 3. Further, the end portions 11 and 12 of the slide member 3 are provided with long holes 11a and 12a, respectively. The shaft 4 (FIG. 2) penetrates the long holes 11a and 12a. That is, one shaft 4 passes through a pair of holes 5 provided at the end 15 of the rail engaging member 2 and a long hole 11 a provided at the end 11 of the slide member 3. Further, as shown in FIG. 2, the shaft 4 passes through the through holes 7 a of the two rollers 7 arranged on both sides of the end portion 15, and screws 8 are screwed into the inner screws 4 a provided at both ends of the shaft 4. Thus, the roller 7 is rotatably attached to the rail engaging member 2. Similarly to the end 15 side, the roller 7 is mounted on the end 16 side by another shaft 4.

また、図４（ａ）、図４（ｂ）に示すようにスライド部材３の端部１１にはばね２５（付勢手段）が設けてある。ばね２５は、レール係合部材２に対してスライド部材３を、レール係合部材２の端部１６側（他端側）へ常時付勢している。 Further, as shown in FIGS. 4A and 4B, the end portion 11 of the slide member 3 is provided with a spring 25 (biasing means). The spring 25 constantly biases the slide member 3 toward the end 16 side (the other end side) of the rail engaging member 2 with respect to the rail engaging member 2.

連結部材１９の上端にはフランジ部２２が固着されている。フランジ部２２の直径は、レール係合部材２に設けた貫通孔１０の直径と、スライド部材３に設けた孔１４の大径部１４ｂの直径よりも小さく、また、孔１４の小径部１４ａの直径よりは大きくなるように設定されている。さらに、フランジ部２２の直下にはロッド２１の小径部２１ａが設けてある。このロッド２１の小径部２１ａの直径は、孔１４の小径部１４ａよりも小さくなるように設定されている。よって、ロッド２１の小径部２１ａは、孔１４の小径部１４ａ内に収容することができる。 A flange portion 22 is fixed to the upper end of the connecting member 19. The diameter of the flange portion 22 is smaller than the diameter of the through hole 10 provided in the rail engaging member 2 and the diameter of the large diameter portion 14 b of the hole 14 provided in the slide member 3, and the diameter of the small diameter portion 14 a of the hole 14. It is set to be larger than the diameter. Further, a small diameter portion 21 a of the rod 21 is provided immediately below the flange portion 22. The diameter of the small diameter portion 21 a of the rod 21 is set to be smaller than the small diameter portion 14 a of the hole 14. Therefore, the small diameter portion 21 a of the rod 21 can be accommodated in the small diameter portion 14 a of the hole 14.

よって、貫通孔１０と孔１４の大径部１４ｂとが重なっている場合には、フランジ部２２は、これらを通過することができる。貫通孔１０と孔１４の小径部１４ａとが重なっている場合には、フランジ部２２は孔１４の小径部１４ａを通過することができないので、
連結部材１９が戸車１に連結された状態を保持することができる。 Therefore, when the through-hole 10 and the large diameter part 14b of the hole 14 overlap, the flange part 22 can pass through these. When the through hole 10 and the small diameter portion 14a of the hole 14 overlap, the flange portion 22 cannot pass through the small diameter portion 14a of the hole 14,
The state where the connecting member 19 is connected to the door pulley 1 can be maintained.

両端にローラ７を備えた軸４は、スライド部材３の端部１１、１２に設けた長孔１１ａ、１２ａの長手方向に移動することができる。すなわち、スライド部材３は、レール係合部材２に対して、長孔１１ａ、１２ａの長手方向に移動することができる。 The shaft 4 provided with the rollers 7 at both ends can move in the longitudinal direction of the long holes 11 a and 12 a provided in the end portions 11 and 12 of the slide member 3. That is, the slide member 3 can move with respect to the rail engaging member 2 in the longitudinal direction of the long holes 11a and 12a.

スライド部材３がレール係合部材２に対して、レール係合部材２の端部１５側（一端側）に移動したときに、孔１４の小径部１４ａの中心がレール係合部材２の貫通孔１０の中心と重なり、逆に端部１２側（他端側）に移動したときに、孔１４の大径部１４ｂの中心が貫通孔１０の中心と重なるようになっている。 When the slide member 3 moves to the end 15 side (one end side) of the rail engaging member 2 with respect to the rail engaging member 2, the center of the small diameter portion 14a of the hole 14 is the through hole of the rail engaging member 2. The center of the large-diameter portion 14b of the hole 14 overlaps the center of the through hole 10 when it moves to the end 12 side (the other end side).

この状況を、図６及び図７に示した。図６、図７は、レール係合部材２とスライド部材３とで構成された戸車１の平面図である。図６は、スライド部材３がレール係合部材２の端部１５側（一端側）に移動した状態を示している。この状態では、レール係合部材２の貫通孔１０の中心と、スライド部材３の大径部１４ｂの中心とが一致している。 This situation is shown in FIGS. FIG. 6 and FIG. 7 are plan views of the door wheel 1 constituted by the rail engaging member 2 and the slide member 3. FIG. 6 shows a state in which the slide member 3 has moved to the end 15 side (one end side) of the rail engagement member 2. In this state, the center of the through hole 10 of the rail engaging member 2 and the center of the large-diameter portion 14b of the slide member 3 coincide with each other.

また、図７は、スライド部材３がレール係合部材２の端部１６側（他端側）に移動した状態を示している。この状態では、レール係合部材２の貫通孔１０の中心と、スライド部材３の小径部１４ａの中心とが一致している。 FIG. 7 shows a state where the slide member 3 has moved to the end 16 side (the other end side) of the rail engagement member 2. In this state, the center of the through hole 10 of the rail engaging member 2 and the center of the small diameter portion 14a of the slide member 3 coincide with each other.

図６及び図７に示すように、戸車１はレール５０上に設置されており、ローラ７は、レール５０上を転がる。また、レール５０に設けた隙間５０ａ上には、スライド部材３の孔１４とレール係合部材２の貫通孔１０とが配置されている。引戸２０（図１）に設置した連結部材１９は、この隙間５０ａを介して戸車１と連結されるようになっている。 As shown in FIGS. 6 and 7, the door roller 1 is installed on the rail 50, and the roller 7 rolls on the rail 50. Further, on the gap 50 a provided in the rail 50, the hole 14 of the slide member 3 and the through hole 10 of the rail engaging member 2 are arranged. The connecting member 19 installed in the sliding door 20 (FIG. 1) is connected to the door pulley 1 through the gap 50a.

図８は、スライド部材３の孔１４とレール係合部材２の貫通孔１０及び連結部材１９のフランジ部２２の位置関係を示す平面図である。図８では、スライド部材３がレール係合部材２の端部１６側（他端側）に移動したときの状態を示している。フランジ部２２が貫通孔１０と大径部１４ｂとを下から上へ通過した後、スライド部材３を端部１６側へ移動させると、フランジ部２２の下に小径部１４ａが配置され、フランジ部２２は孔１４（小径部１４ａ）を下方向に逆に通過することができなくなり、戸車１と連結部材１９とがロックされる。 FIG. 8 is a plan view showing the positional relationship between the hole 14 of the slide member 3, the through hole 10 of the rail engaging member 2, and the flange portion 22 of the connecting member 19. FIG. 8 shows a state where the slide member 3 has moved to the end 16 side (the other end side) of the rail engagement member 2. After the flange portion 22 has passed through the through hole 10 and the large diameter portion 14b from the bottom to the top, when the slide member 3 is moved to the end portion 16 side, the small diameter portion 14a is disposed under the flange portion 22, and the flange portion No. 22 cannot pass through the hole 14 (small diameter portion 14a) in the downward direction, and the door wheel 1 and the connecting member 19 are locked.

スライド部材３がレール係合部材２に対して、孔１４の小径部１４ａの中心から大径部１４ｂの中心までの長さＬ３を移動することができるように、レール係合部材２の中央部１７の長さＬ１とスライド部材３の中央部１３の長さＬ２の差は、長さＬ３と等しいか又は大きくなるように設定されている。 The central portion of the rail engaging member 2 is such that the slide member 3 can move a length L3 from the center of the small diameter portion 14a of the hole 14 to the center of the large diameter portion 14b with respect to the rail engaging member 2. The difference between the length L1 of 17 and the length L2 of the central portion 13 of the slide member 3 is set to be equal to or greater than the length L3.

ところで、レール係合部材２に対するスライド部材３の自由なスライド移動を容認すると、レール５０（図１）から引戸２０（図１）が落下する恐れがある。そのため、レール係合部材２の端部１６側にスライド部材３が配置されている状態（図７に示す状態）からスライド部材３がレール係合部材２の端部１５側に移動して図６に示す状態とならないように、スライド部材３とレール係合部材２には移動を阻止するロック機構を設けるのが好ましい。 By the way, if the sliding movement of the sliding member 3 with respect to the rail engaging member 2 is permitted, the sliding door 20 (FIG. 1) may fall from the rail 50 (FIG. 1). Therefore, the slide member 3 moves from the state in which the slide member 3 is disposed on the end 16 side of the rail engaging member 2 (the state shown in FIG. 7) to the end 15 side of the rail engaging member 2, and FIG. It is preferable that the slide member 3 and the rail engagement member 2 are provided with a lock mechanism for preventing movement so that the state shown in FIG.

本実施形態のロック機構は、レール係合部材２に設けた前述の段２３と、スライド部材３の下面に設けた突起２４とで構成されている。図７に示すように、スライド部材３がレール係合部材２の端部１６側に移動した際には、突起２４が段２３に係合しており、スライド部材３がレール係合部材２の端部１５側（一端側）へ移動することを阻止している。 The lock mechanism of the present embodiment includes the above-described step 23 provided on the rail engagement member 2 and a protrusion 24 provided on the lower surface of the slide member 3. As shown in FIG. 7, when the slide member 3 moves to the end 16 side of the rail engaging member 2, the protrusion 24 is engaged with the step 23, and the slide member 3 is connected to the rail engaging member 2. The movement to the end 15 side (one end side) is prevented.

一方、戸車１に連結部材１９を連結する際や、戸車１から連結部材１９を取り外す際には、スライド部材３をレール係合部材２の端部１５側（一端側）に移動させ、図６に示す状態にしなければならない。その際には、スライド部材３の端部１２を、例えば指で上方へ押し上げ、突起２４と段２３の係合を解除する。さらに、そのままの状態でスライド部材３をばね２５の弾性力に抗してレール係合部材２の端部１５側（一端側）へ移動させ、スライド部材３の孔１４の大径部１４ｂの中心と、レール係合部材２の貫通孔１０の中心とを一致させ、フランジ部２２を大径部１４ｂと貫通孔１０を下方へ通過させて、戸車１から連結部材１９（引戸２０）を取り外す。 On the other hand, when connecting the connecting member 19 to the door roller 1 or removing the connecting member 19 from the door wheel 1, the slide member 3 is moved to the end portion 15 side (one end side) of the rail engaging member 2, and FIG. It must be in the state shown in. At that time, the end 12 of the slide member 3 is pushed upward with, for example, a finger, and the engagement between the protrusion 24 and the step 23 is released. Further, the slide member 3 is moved to the end 15 side (one end side) of the rail engagement member 2 against the elastic force of the spring 25 in the state as it is, and the center of the large diameter portion 14b of the hole 14 of the slide member 3 is moved. Then, the center of the through hole 10 of the rail engaging member 2 is matched, the flange portion 22 is passed through the large diameter portion 14b and the through hole 10 downward, and the connecting member 19 (sliding door 20) is removed from the door wheel 1.

この一連の動作を図９（ａ）〜図９（ｄ）に示した。図９（ａ）〜図９（ｄ）は、戸車１の縦断側面図である。図９（ａ）は、スライド部材３の端部１２を押し上げた状態を示している。スライド部材３の端部１２を押し上げると、スライド部材３の突起２４が、レール係合部材２の段２３から外れ、ロック機構が解除される。 This series of operations is shown in FIGS. 9A to 9D. FIG. 9A to FIG. 9D are longitudinal side views of the door pulley 1. FIG. 9A shows a state in which the end 12 of the slide member 3 is pushed up. When the end portion 12 of the slide member 3 is pushed up, the protrusion 24 of the slide member 3 is disengaged from the step 23 of the rail engaging member 2, and the lock mechanism is released.

次に、図９（ｂ）に示すように、スライド部材３をばね２５の弾性力に抗して、レール係合部材２の端部１５側（一端側）へ移動させる。図９（ｂ）に示す状態では、スライド部材３の孔１４の大径部１４ｂの中心とレール係合部材２の貫通孔１０の中心とが一致している。そして、図９（ｃ）に示すように、連結部材１９のロッド２１の先端（フランジ部２２）を下方から上方へ移動させ、一致した貫通孔１０と孔１４の大径部１４ｂとを通過させる。さらに、図９（ｄ）に示すように、スライド部材３をレール係合部材２の端部１６側へ移動させ、突起２４を段２３に係合させる。図９（ｄ）に示す状態では、スライド部材３の孔１４の小径部１４ａの中心とレール係合部材２の貫通孔１０の中心とが一致しており、フランジ部２２は小径部１４ａの縁で支持されている。 Next, as shown in FIG. 9B, the slide member 3 is moved to the end 15 side (one end side) of the rail engagement member 2 against the elastic force of the spring 25. In the state shown in FIG. 9B, the center of the large diameter portion 14 b of the hole 14 of the slide member 3 and the center of the through hole 10 of the rail engaging member 2 coincide with each other. Then, as shown in FIG. 9C, the tip (flange portion 22) of the rod 21 of the connecting member 19 is moved upward from below, and the matched through hole 10 and large diameter portion 14b of the hole 14 are passed. . Further, as shown in FIG. 9 (d), the slide member 3 is moved to the end 16 side of the rail engaging member 2, and the protrusion 24 is engaged with the step 23. In the state shown in FIG. 9D, the center of the small diameter portion 14a of the hole 14 of the slide member 3 and the center of the through hole 10 of the rail engaging member 2 are coincident, and the flange portion 22 is the edge of the small diameter portion 14a. It is supported by.

以上、説明したレール係合部材２とスライド部材３は、比較的軽量で加工しやすい素材で成形するのが好ましい。万が一、これらに不測の外力が作用して戸車１が破壊されたときに備え、引戸２０が落下しないように、レール係合部材２とスライド部材３の間に、図５に示す補強部材２６を設けるのが好ましい。 As described above, the rail engaging member 2 and the slide member 3 described above are preferably formed of a material that is relatively light and easy to process. In the unlikely event that an unexpected external force acts on these and the door wheel 1 is destroyed, a reinforcing member 26 shown in FIG. 5 is provided between the rail engaging member 2 and the slide member 3 so that the sliding door 20 does not fall. It is preferable to provide it.

補強部材２６は、剛性を備えた金属で構成し、スライド部材３の孔１４と同様の孔２７を備えている。スライド部材３の孔１４と補強部材２６の孔２７とを、小径部同士及び大径部同士が一致するように重ね、補強部材２６をスライド部材３と一体化（例えばねじ止め、接着等）させる。このようにすれば、万が一、スライド部材３が破壊されても、補強部材２６がレール５０上に残って引戸２０（図１）を支持し、引戸２０がレール５０から落下することを防止することができる。 The reinforcing member 26 is made of a metal having rigidity, and includes a hole 27 similar to the hole 14 of the slide member 3. The hole 14 of the slide member 3 and the hole 27 of the reinforcement member 26 are overlapped so that the small diameter portions and the large diameter portions coincide with each other, and the reinforcement member 26 is integrated with the slide member 3 (for example, screwing, bonding, etc.). . In this way, even if the slide member 3 is destroyed, the reinforcing member 26 remains on the rail 50 to support the sliding door 20 (FIG. 1) and prevent the sliding door 20 from falling from the rail 50. Can do.

連結部材１９の引戸２０に対する固定方法は、従来の引戸と同様の方法を用いる。また、ロッド２１の長さを調整し、レール５０と引戸２０とが適当な位置関係となるようにする機構についても、従来の構造（ロッドに設けた斜面に、ねじの端面を押し当て、ねじのねじ込み加減を調整することで引戸からのロッドの露出量を調整する構造）をそのまま採用する。 The method of fixing the connecting member 19 to the sliding door 20 uses the same method as the conventional sliding door. Further, with respect to a mechanism that adjusts the length of the rod 21 so that the rail 50 and the sliding door 20 are in an appropriate positional relationship, the screw end face is pressed against the slope provided on the rod. The structure that adjusts the amount of exposure of the rod from the sliding door by adjusting the amount of screwing is adopted as it is.
