Description

本発明は、上枠の長手方向に移動する開閉体を備えた建具に関する。 The present invention relates to a fitting having an opening / closing body that moves in the longitudinal direction of the upper frame.

ケンドン式の開閉体を枠体に取り付けるときには、開閉体を斜めにした状態で上枠に取り付け、開閉体を上方に移動させる。続いて、開閉体を垂直にした状態で、開閉体を下方に移動させて、開閉体を下枠に取り付ける。これにより、開閉体は、枠体に移動可能に取り付けられ、上枠の長手方向に移動する。ところが、ケンドン式の開閉体が衝撃を受けると、開閉体が上方に移動して、下枠と上枠から開閉体が外れる虞がある。そこで、従来、上外れ止め具と下外れ止め具により、障子(開閉体)の上方移動を規制するサッシが知られている(特許文献1参照)。 When attaching the Kendon type opening / closing body to the frame body, the opening / closing body is attached to the upper frame in a slanted state, and the opening / closing body is moved upward. Subsequently, with the opening / closing body vertical, the opening / closing body is moved downward to attach the opening / closing body to the lower frame. As a result, the opening / closing body is movably attached to the frame body and moves in the longitudinal direction of the upper frame. However, when the Kendon type opening / closing body receives an impact, the opening / closing body may move upward and the opening / closing body may come off from the lower frame and the upper frame. Therefore, conventionally, there is known a sash that regulates the upward movement of a shoji (opening and closing body) by using an upper stopper and a lower stopper (see Patent Document 1).

特許文献1に記載された従来のサッシでは、開閉体の上方移動を規制することで、開閉体が下枠から外れるのを抑制し、サッシの下枠側で、開閉体が倒れるのを抑制する。しかしながら、従来のサッシでは、開閉体の上方移動を規制するために、2つの外れ止め具を設けており、サッシの構造が複雑になることがある。また、サッシの外観等の観点から、外れ止め具が見え難い位置に設けられており、外れ止め具が機能を発揮する状態であるのか視認し難い。外れ止め具と接触する部分と外れ止め具との間の隙間を調整する作業も行い難く、隙間の調整作業に手間がかかる虞もある。 In the conventional sash described in Patent Document 1, by restricting the upward movement of the opening / closing body, the opening / closing body is suppressed from coming off from the lower frame, and the opening / closing body is suppressed from falling on the lower frame side of the sash. .. However, in the conventional sash, two stoppers are provided in order to restrict the upward movement of the opening / closing body, and the structure of the sash may be complicated. Further, from the viewpoint of the appearance of the sash, the stopper is provided at a position where it is difficult to see, and it is difficult to visually recognize whether the stopper is in a state of exerting its function. It is also difficult to adjust the gap between the portion that comes into contact with the stopper and the stopper, and there is a risk that the gap adjustment work will take time and effort.

これに対し、下枠の段差の低減が求められる建具(例えば、浴室用のドア)では、下枠の上下方向の寸法が小さくなるのに伴い、下外れ止め具を設け難くなり、下枠における開閉体の取付部の寸法も小さくなる。そのため、下枠側で、開閉体が倒れるのを抑制するのが困難になる。また、上枠側で、上外れ止め具と開閉体の間の隙間を、より正確に調整する必要があり、隙間の調整作業の手間が増加する虞もある。 On the other hand, in fittings (for example, bathroom doors) that are required to reduce the step difference of the lower frame, as the vertical dimension of the lower frame becomes smaller, it becomes difficult to provide a lower stopper, and the lower frame becomes difficult to provide. The size of the mounting part of the opening / closing body is also reduced. Therefore, it becomes difficult to prevent the opening / closing body from falling on the lower frame side. Further, on the upper frame side, it is necessary to more accurately adjust the gap between the upper stopper and the opening / closing body, which may increase the time and effort for adjusting the gap.

特許第4870966号公報Japanese Patent No. 4870966

本発明の建具の一実施形態について、図面を参照して説明する。
本実施形態の建具は、スライド式の開閉体を備えた建具である。以下では、片引戸を例にとり、建具の2つの実施形態について説明する。また、建具は、浴室用のドアであり、浴室の出入口に設置される。
An embodiment of the fitting of the present invention will be described with reference to the drawings.
The fitting of the present embodiment is a fitting provided with a sliding opening / closing body. In the following, two embodiments of fittings will be described by taking a single sliding door as an example. The fittings are bathroom doors and are installed at the entrances and exits of the bathrooms.

(第1実施形態)
図1は、第1実施形態の建具1の正面図であり、脱衣室側からみた建具1の概略構成を模式的に示している。図1において、水平方向は左右方向であり、垂直方向は上下方向である。
図示のように、建具1は、外動引戸であり、枠体4と、枠体4に固定された固定体10と、枠体4に開閉可能に取り付けられた開閉体20を備えている。枠体4は、建物の開口部に設置される方形状の引戸枠であり、方形状の固定体10と開閉体20を囲む。枠体4の内側部は、開口部4Aと、固定体10により閉鎖される閉鎖部4Bからなる。枠体4の内側部において、開口部4Aは、左右方向の一方側部であり、閉鎖部4Bは、左右方向の他方側部である。
(First Embodiment)
FIG. 1 is a front view of the fitting 1 of the first embodiment, and schematically shows the schematic configuration of the fitting 1 as viewed from the dressing room side. In FIG. 1, the horizontal direction is the horizontal direction, and the vertical direction is the vertical direction.
As shown in the figure, the fitting 1 is an external sliding door, and includes a frame body 4, a fixed body 10 fixed to the frame body 4, and an opening / closing body 20 attached to the frame body 4 so as to be openable / closable. The frame body 4 is a rectangular sliding door frame installed at an opening of a building, and surrounds a rectangular fixed body 10 and an opening / closing body 20. The inner portion of the frame body 4 includes an opening portion 4A and a closing portion 4B closed by the fixed body 10. In the inner portion of the frame body 4, the opening 4A is one side portion in the left-right direction, and the closing portion 4B is the other side portion in the left-right direction.

固定体10が枠体4の閉鎖部4Bに配置され、固定体10と開閉体20が枠体4の奥行方向にずらして配置される。開閉体20は、スライドにより移動する可動体(障子)であり、枠体4内の移動領域で、所定の移動方向に移動する。移動領域は、開閉体20のスライド領域であり、移動方向は、開閉体20のスライド方向(ここでは、左右方向)である。スライド移動により、開閉体20は、枠体4の開口部4Aと閉鎖部4Bとに移動して開閉する。開閉体20により、枠体4の開口部4Aが開閉される。 The fixed body 10 is arranged in the closed portion 4B of the frame body 4, and the fixed body 10 and the opening / closing body 20 are arranged so as to be offset in the depth direction of the frame body 4. The opening / closing body 20 is a movable body (shoji) that moves by sliding, and moves in a predetermined moving direction in a moving area in the frame body 4. The moving area is the slide area of the opening / closing body 20, and the moving direction is the sliding direction of the opening / closing body 20 (here, the left-right direction). By the sliding movement, the opening / closing body 20 moves to the opening 4A and the closing portion 4B of the frame body 4 to open / close. The opening / closing body 20 opens / closes the opening 4A of the frame body 4.

開口部4Aの閉鎖時に、開閉体20は、移動方向の一方側(閉鎖方向)に移動(スライド)して、枠体4の開口部4Aに配置される。これにより、開閉体20は、枠体4の開口部4Aを閉鎖する全閉位置に配置される。開口部4Aの開放時に、開閉体20は、移動方向の他方側(開放方向)に移動して、枠体4の閉鎖部4Bに配置される。これにより、開閉体20は、枠体4の開口部4Aを開放する全開位置に配置されて、枠体4の奥行方向において固定体10と重なる。 When the opening 4A is closed, the opening / closing body 20 moves (slides) to one side (closing direction) in the moving direction and is arranged in the opening 4A of the frame body 4. As a result, the opening / closing body 20 is arranged at a fully closed position that closes the opening 4A of the frame body 4. When the opening 4A is opened, the opening / closing body 20 moves to the other side (opening direction) in the moving direction and is arranged in the closing portion 4B of the frame body 4. As a result, the opening / closing body 20 is arranged at a fully open position that opens the opening 4A of the frame body 4, and overlaps with the fixed body 10 in the depth direction of the frame body 4.

図2〜図4は、第1実施形態の建具1の断面図である。図2は、建具1を図1のX1−X1線で切断した縦断面図であり、枠体4の開口部4Aにおける断面を示している。図3は、建具1を図1のX2−X2線で切断した縦断面図であり、枠体4の閉鎖部4Bにおける断面を示している。図4は、建具1を図1のX3−X3線で切断した横断面図であり、開閉体20により枠体4の開口部4Aを閉鎖した状態を示している。 2 to 4 are cross-sectional views of the fitting 1 of the first embodiment.

図7は、第1実施形態の建具1において突起部60が外れ止め部54に接触した状態を示す断面図であり、図5と同様に、上枠5を含む建具1の一部を示している。
図示のように、開閉体20が衝撃等を受けたときには、開閉体20が下枠6のレール6Bから外れて、開閉体20の下縁部が下枠6の見込み方向に移動することがある。このように、開閉体20が下枠6から外れたときには、開閉体20は、上下方向に対して斜めになり、突起部60とともに下方に移動する。ここでは、開閉体20は、下枠6に対して脱衣室側に外れる。
FIG. 7 is a cross-sectional view showing a state in which the protrusion 60 is in contact with the retaining portion 54 in the fitting 1 of the first embodiment, and similarly to FIG. 5, a part of the fitting 1 including the upper frame 5 is shown. There is.
As shown in the figure, when the opening / closing body 20 receives an impact or the like, the opening / closing body 20 may come off from the rail 6B of the lower frame 6 and the lower edge portion of the opening / closing body 20 may move in the prospective direction of the lower frame 6. .. In this way, when the opening / closing body 20 is removed from the lower frame 6, the opening / closing body 20 becomes slanted with respect to the vertical direction and moves downward together with the protrusion 60. Here, the opening / closing body 20 is detached from the lower frame 6 toward the dressing room side.

開閉体20の突起部60は、下方への移動に伴い、引っ掛かり部である外れ止め部54に接触して、外れ止め部54に引っ掛かる。突起部60は、外れ止め部54により支えられて、外れ止め部54に保持される。その結果、開閉体20が上枠5から外れるのが抑制される。このように、建具1は、上枠5と開閉体20に設けられた外れ止め機構16を備える。外れ止め機構16は、少なくとも突起部60、外れ止め部54、及び、覆い部53を有し、開閉体20を上枠5に保持する。外れ止め機構16により、開閉体20が上枠5から外れるのが阻止されて、開閉体20が倒れるのが抑制される。 As the opening / closing body 20 moves downward, the protrusion 60 comes into contact with the retaining portion 54, which is a hooking portion, and is hooked on the retaining portion 54. The protrusion 60 is supported by the retaining portion 54 and held by the retaining portion 54. As a result, the opening / closing body 20 is prevented from coming off the upper frame 5. As described above, the fitting 1 includes the upper frame 5 and the retaining mechanism 16 provided on the opening / closing body 20. The retaining mechanism 16 has at least a protrusion 60, a retaining portion 54, and a covering portion 53, and holds the opening / closing body 20 in the upper frame 5. The retaining mechanism 16 prevents the opening / closing body 20 from coming off the upper frame 5, and prevents the opening / closing body 20 from falling over.

開閉体20が上枠5の規制部(レール5E)に接触する状態(規制部により開閉体20の移動が規制された状態)で、開閉体20の突起部60は、外れ止め部54の上方に配置される。開閉体20が下枠6から外れたときには、開閉体20がレール5Eに接触し、レール5Eにより、上枠5の見込み方向への開閉体20の移動が規制される。その状態で、突起部60が外れ止め部54に引っ掛かる。開閉体20は、外れ止め部54とレール5Eにより支えられて上枠5に保持される。従って、外れ止め機構16は、突起部60、外れ止め部54、及び、覆い部53に加えて、規制部(レール5E)を有し、開閉体20を保持することで、開閉体20が上枠5から外れるのを抑制する。 In a state where the opening / closing body 20 is in contact with the regulating portion (rail 5E) of the upper frame 5 (a state in which the movement of the opening / closing body 20 is restricted by the regulating portion), the protrusion 60 of the opening / closing body 20 is above the retaining portion 54. Is placed in. When the opening / closing body 20 comes off from the lower frame 6, the opening / closing body 20 comes into contact with the rail 5E, and the rail 5E restricts the movement of the opening / closing body 20 in the prospective direction of the upper frame 5. In that state, the protrusion 60 is caught by the retaining portion 54. The opening / closing body 20 is supported by the retaining portion 54 and the rail 5E and held by the upper frame 5. Therefore, the retaining mechanism 16 has a regulating portion (rail 5E) in addition to the protrusion 60, the retaining portion 54, and the covering portion 53, and by holding the opening / closing body 20, the opening / closing body 20 is raised. Suppresses the frame 5 from coming off.

図8は、図7の一部を示す断面図であり、上枠5の長手方向に直交する断面を示している。
図示のように、開閉体20が下枠6から外れた状態で、開閉体20の第1壁部41の接触部44が上枠5のレール5Eに接触し、突起部60の下面部62が外れ止め部54の先端部56に接触する。レール5Eの下端部5Fと外れ止め部54の先端部56の間隔をK1、開閉体20の接触部44と下面部62の先端部63の間の寸法をK2とする。この場合に、K1はK2より小さい(K1<K2)。そのため、レール5Eと外れ止め部54の間において、突起部60を含む開閉体20がレール5Eと外れ止め部54の間の部分から抜けるのが抑制される。
FIG. 8 is a cross-sectional view showing a part of FIG. 7, and shows a cross section orthogonal to the longitudinal direction of the upper frame 5.
As shown in the figure, with the opening / closing body 20 detached from the lower frame 6, the contact portion 44 of the first wall portion 41 of the opening / closing body 20 contacts the rail 5E of the upper frame 5, and the lower surface portion 62 of the protrusion 60 It comes into contact with the tip 56 of the retaining portion 54. The distance between the lower end portion 5F of the rail 5E and the tip portion 56 of the retaining portion 54 is K1, and the dimension between the contact portion 44 of the opening / closing body 20 and the tip portion 63 of the lower surface portion 62 is K2. In this case, K1 is smaller than K2 (K1 <K2). Therefore, between the rail 5E and the retaining portion 54, the opening / closing body 20 including the protrusion 60 is prevented from coming off from the portion between the rail 5E and the retaining portion 54.

以上説明したように、第1実施形態の建具1では、開閉体20が上枠5から外れるのを容易に抑制でき、建具1の上枠5側で、開閉体20が倒れるのを抑制することができる。開閉体20が下枠6から外れたときでも、外れ止め部54により突起部60の移動を規制することで、開閉体20の倒れを抑制することができる。外れ止め部54を突起部60の下方に配置することで、突起部60の下方への移動が規制される。従って、開閉体20及び突起部60の上下方向の位置の調整が容易になり、又は、開閉体20及び突起部60の上下方向の位置の調整が不要になる。 As described above, in the fitting 1 of the first embodiment, it is possible to easily prevent the opening / closing body 20 from coming off from the upper frame 5, and to prevent the opening / closing body 20 from falling on the upper frame 5 side of the fitting 1. Can be done. Even when the opening / closing body 20 comes off from the lower frame 6, the opening / closing body 20 can be prevented from falling by restricting the movement of the protrusion 60 by the retaining portion 54. By arranging the retaining portion 54 below the protrusion 60, the downward movement of the protrusion 60 is restricted. Therefore, the vertical positions of the opening / closing body 20 and the protrusion 60 can be easily adjusted, or the vertical positions of the opening / closing body 20 and the protrusion 60 do not need to be adjusted.

覆い部53により突起部60が覆われているか否かに基づいて、突起部60に対する外れ止め部54の位置を判断することができる。また、覆い部53により、外れ止め部54による外れ止めの機能の状態を視認でき、外れ止めの機能が発揮される状態であるのか容易に判断することができる。開閉体20の上下方向の位置の調整、又は、上枠5の反りにより、突起部60が覆い部53により覆われる位置で変位しても、突起部60を外れ止め部54に引っ掛けることができる。覆い部53により、建具1の上枠5側の外観を向上させることもできる。 The position of the retaining portion 54 with respect to the protrusion 60 can be determined based on whether or not the protrusion 60 is covered by the covering portion 53. Further, the cover portion 53 allows the state of the retaining function of the retaining portion 54 to be visually recognized, and it is possible to easily determine whether or not the retaining function is exhibited. Even if the protrusion 60 is displaced at a position covered by the covering portion 53 due to the adjustment of the vertical position of the opening / closing body 20 or the warp of the upper frame 5, the protrusion 60 can be hooked on the retaining portion 54. .. The covering portion 53 can also improve the appearance of the fitting 1 on the upper frame 5 side.

覆い部53と外れ止め部54は、カバー部材50に設けられる。カバー部材50を取り外した状態で、開閉体20を上枠5に容易に取り付けることができる。また、突起部60に対する覆い部53と外れ止め部54の配置を容易に行うことができる。外れ止め部54を突起部60の下面部62と対向させることで、突起部60を外れ止め部54に、より確実に接触させることができる。 The cover portion 53 and the retaining portion 54 are provided on the cover member 50. With the cover member 50 removed, the opening / closing body 20 can be easily attached to the upper frame 5.
