Description

本発明は、枠体の開口部に配置される開閉体を備えた建具に関する。 The present invention relates to a fitting including an opening / closing body arranged in an opening of a frame.

建物の開口部に設置される建具では、枠体の複数の枠により開口部が形成されて、開閉体が枠体の開口部に配置される。開閉体は、枠体に開閉可能に連結され、開閉操作に応じて開閉される。また、従来、障子（開閉体）が閉じたときに、ドア枠（枠体）のタイト材を障子に接触させる建具が知られている（特許文献１参照）。 In a fitting installed in an opening of a building, the opening is formed by a plurality of frames of the frame, and the opening / closing body is arranged in the opening of the frame. The opening / closing body is openably / closably connected to the frame body and is opened / closed according to an opening / closing operation. Further, conventionally, a fitting has been known in which the tight material of the door frame (frame body) is brought into contact with the shoji when the shoji (opening / closing body) is closed (see Patent Document 1).

特許文献１に記載された従来の建具では、タイト材ホルダーが枠から突出して形成され、タイト材がタイト材ホルダーに取り付けられる。ところが、従来の建具では、タイト材ホルダー等の形成に伴い、枠の構造が複雑になり、複数の枠を簡単に枠組みできないことがある。また、枠の端部同士を組み合わせるため、枠の端部を切断した後、タイト材ホルダー等を他の枠の形状に対応して加工する必要がある。そのため、枠の端部の構造を含む建具の構造が複雑になる虞がある。加えて、タイト材ホルダーの形成に伴い、建具の有効開口が減少することがある。タイト材ホルダーへの衝突が懸念されるため、安全性の観点からも改良の余地がある。 In the conventional fitting described in Patent Document 1, the tight material holder is formed so as to project from the frame, and the tight material is attached to the tight material holder. However, in the conventional fittings, the structure of the frame becomes complicated due to the formation of the tight material holder and the like, and thus it may not be possible to easily form a plurality of frames. Further, since the end portions of the frame are combined with each other, it is necessary to cut the end portions of the frame and then process the tight material holder or the like in accordance with the shapes of other frames. Therefore, the structure of the fitting including the structure of the end portion of the frame may be complicated. In addition, the formation of the tight material holder may reduce the effective opening of the fitting. There is room for improvement from a safety point of view because there is concern about collision with the tight material holder.

建具の設置場所によっては、建具の一方側と他方側とで通気を行うことが求められる。例えば、トイレのドアでは、トイレ内の換気のため、障子が閉じた状態で、室内側と室外側との通気により、空気を流通させる必要がある。しかしながら、従来の建具では、障子に接触するタイト材により空気の流通が阻害されるため、通気を簡単に行うことができない。これに対し、建具に通気路を形成するときには、通気路を通して室内側が視認されることが懸念される。従って、プライバシーの観点から、問題が生じる虞がある。 Depending on the installation location of the fitting, ventilation is required on one side and the other side of the fitting. For example, in a toilet door, in order to ventilate the inside of the toilet, it is necessary to circulate air by ventilating the inside and outside of the room with the shoji screen closed. However, in the conventional fittings, the tight material contacting the shoji blocks the air flow, so that the ventilation cannot be performed easily. On the other hand, when forming the ventilation path in the fitting, there is a concern that the inside of the room is visually recognized through the ventilation path. Therefore, a problem may occur from the viewpoint of privacy.

内周面部６Ａは、縦枠６の見込み方向に沿って形成された縦枠６の側面部であり、開閉体３の外周部の一部（側部）と対向する。内周面部６Ａの開閉体３側（開口部２Ａの内方側）の面は、平面状に形成された平坦面になっている。取付部６Ｃは、内周面部６Ａに溝状に形成された溝部（取付溝部）であり、内周面部６Ａに対して開口部２Ａの外方側にくぼむ。また、取付部６Ｃは、縦枠６の見込み方向の一方側（室内側）に位置する内周面部６Ａの一方側部（ここでは、端部）に形成され、縦枠６の長手方向に沿って延びる。取付部６Ｃは、２つの係止部６Ｄを有する。２つの係止部６Ｄは、取付部６Ｃ内で縦枠６の見込み方向に突出して、互いに対向する。 The inner peripheral surface portion 6A is a side surface portion of the vertical frame 6 formed along the prospective direction of the vertical frame 6, and faces a part (side portion) of the outer peripheral portion of the opening / closing body 3. The surface of the inner peripheral surface portion 6A on the opening / closing body 3 side (the inner side of the opening portion 2A) is a flat surface formed in a planar shape. The mounting portion 6C is a groove portion (mounting groove portion) formed in a groove shape on the inner peripheral surface portion 6A, and is recessed to the outer side of the opening 2A with respect to the inner peripheral surface portion 6A. The mounting portion 6C is formed on one side portion (here, the end portion) of the inner peripheral surface portion 6A located on one side (inside the room) of the vertical frame 6 in the prospective direction, and extends along the longitudinal direction of the vertical frame 6. Extend. The mounting portion 6C has two locking portions 6D. The two locking portions 6D project in the prospective direction of the vertical frame 6 in the mounting portion 6C and face each other.

内周面部６Ａは、取付部６Ｃから縦枠６の見込み方向の他方側（室外側）に向かって延びる。複数の支持部６Ｂのうち、室外側の１つの支持部６Ｂは、内周面部６Ａから開口部２Ａの外方側（建物１０の開口縁部１３）に向かって突出する中空状の突出部であり、室内側の２つの支持部６Ｂは、取付部６Ｃから開口部２Ａの外方側に向かって突出する突片である。複数の支持部６Ｂは、開口縁部１３に接触して、内周面部６Ａと取付部６Ｃを支持する。 The inner peripheral surface portion 6A extends from the mounting portion 6C toward the other side (outdoor side) of the vertical frame 6 in the prospective direction. Of the plurality of support portions 6B, one support portion 6B on the outdoor side is a hollow protrusion that protrudes from the inner peripheral surface portion 6A toward the outside of the opening 2A (opening edge portion 13 of the building 10). The two support portions 6B on the indoor side are projection pieces that project from the attachment portion 6C toward the outside of the opening 2A. The plurality of supporting portions 6B contact the opening edge portion 13 and support the inner peripheral surface portion 6A and the mounting portion 6C.

縦枠６の見込み部６Ｅは、内周面部６Ａと取付部６Ｃの開口６Ｆからなり、縦枠６の見込み方向に沿って形成される。見込み部６Ｅ及び内周面部６Ａは、縦枠６において最も開口部２Ａの内方側に位置し、取付部６Ｃの開口６Ｆを除いて平坦に形成されている。取付部６Ｃは、内周面部６Ａ（見込み部６Ｅ）の室内側部に形成されて、内周面部６Ａに開口する。 The prospective portion 6E of the vertical frame 6 includes an inner peripheral surface portion 6A and an opening 6F of the mounting portion 6C, and is formed along the prospective direction of the vertical frame 6. The prospective portion 6E and the inner peripheral surface portion 6A are located on the innermost side of the opening 2A in the vertical frame 6, and are formed flat except the opening 6F of the mounting portion 6C. The mounting portion 6C is formed on the indoor side of the inner peripheral surface portion 6A (prospecting portion 6E) and opens to the inner peripheral surface portion 6A.

建具１は、縦枠６と開閉体３の間に形成される通気路７と、縦枠６に取り付けられる軟質な縦突出部材５０を備える。通気路７は、縦枠６と開閉体３の縦縁部３Ｃの間に形成される隙間であり、開閉体３の室内側の空間と室外側の空間とに向かって開口する。また、通気路７は、縦枠６の長手方向に沿って形成されて、縦枠６と開閉体３の縦縁部３Ｃの間の部分の全体にわたって形成されている。 The fitting 1 includes a ventilation path 7 formed between the vertical frame 6 and the opening / closing body 3, and a soft vertical protruding member 50 attached to the vertical frame 6. The ventilation path 7 is a gap formed between the vertical frame 6 and the vertical edge portion 3C of the opening / closing body 3, and opens toward the space on the indoor side and the space on the outdoor side of the opening / closing body 3. Further, the ventilation path 7 is formed along the longitudinal direction of the vertical frame 6 and is formed over the entire portion between the vertical frame 6 and the vertical edge portion 3C of the opening / closing body 3.

通気路７は、開閉体３が閉じた状態で、縦枠６の内周面部６Ａと開閉体３の間に形成される。開閉体３が閉じた状態で、通気路７は、開閉体３の室内側の空間と室外側の空間との間で空気を流通させる。空気は、通気路７を通って、開閉体３の室内側から室外側に通過し、開閉体３の室外側から室内側に通過する。 The ventilation path 7 is formed between the inner peripheral surface portion 6A of the vertical frame 6 and the opening / closing body 3 in a state where the opening / closing body 3 is closed. When the opening / closing body 3 is closed, the ventilation path 7 allows air to flow between the space on the indoor side and the space on the outdoor side of the opening / closing body 3. The air passes from the indoor side of the opening / closing body 3 to the outdoor side through the ventilation path 7, and passes from the outdoor side of the opening / closing body 3 to the indoor side.

縦突出部材５０は、ベース部５１と、２つの被係止部５２と、突片５３を有し、縦枠６の長手方向に沿って配置される。被係止部５２は、ベース部５１に形成された溝部であり、突片５３は、ベース部５１から開口部２Ａの内方側に向かって突出する。縦突出部材５０の取り付け時には、ベース部５１が縦枠６の取付部６Ｃに挿入される。また、取付部６Ｃの係止部６Ｄが被係止部５２内に配置されて、ベース部５１が係止部６Ｄに係止される。これにより、縦突出部材５０が取付部６Ｃに着脱可能に係止される。 The vertical protruding member 50 has a base portion 51, two locked portions 52, and a protruding piece 53, and is arranged along the longitudinal direction of the vertical frame 6. The locked portion 52 is a groove formed in the base portion 51, and the projecting piece 53 projects from the base portion 51 toward the inner side of the opening 2A. When the vertical protruding member 50 is attached, the base portion 51 is inserted into the attachment portion 6C of the vertical frame 6. Further, the locking portion 6D of the mounting portion 6C is arranged inside the locked portion 52, and the base portion 51 is locked to the locking portion 6D. As a result, the vertical protruding member 50 is detachably locked to the mounting portion 6C.

縦突出部材５０は、縦枠６の取付部６Ｃに取り付けられて、縦枠６及び内周面部６Ａから開口部２Ａの内方側に突出する。ここでは、縦突出部材５０の突片５３が、開閉体３よりも室内側で、開閉体３の縦縁部３Ｃに向かって突出する。縦突出部材５０（突片５３）は、通気路７及び開閉体３の縦縁部３Ｃ（縦框３４）に対して縦枠６の見込み方向の一方側（室内側）に配置されて、開閉体３の縦縁部３Ｃに隣接する。また、縦突出部材５０は、開閉体３に接触せず、開閉体３の縦縁部３Ｃから離間した位置に配置される。 The vertical protrusion member 50 is attached to the attachment portion 6C of the vertical frame 6 and protrudes from the vertical frame 6 and the inner peripheral surface portion 6A toward the inner side of the opening 2A. Here, the projecting piece 53 of the vertical projecting member 50 projects toward the vertical edge portion 3C of the opening / closing body 3 on the indoor side of the opening / closing body 3. The vertical projecting member 50 (projection piece 53) is arranged on one side (indoor side) of the vertical frame 6 in the prospective direction with respect to the ventilation path 7 and the vertical edge portion 3C (vertical frame 34) of the opening / closing body 3 to open and close. Adjacent to the vertical edge 3C of the body 3. The vertical protruding member 50 does not contact the opening / closing body 3 and is arranged at a position separated from the vertical edge portion 3C of the opening / closing body 3.

開閉体３が閉じた状態で、縦突出部材５０は、開閉体３の縦縁部３Ｃに沿って配置されて、開閉体３との間に隙間５４を形成する。隙間５４は、開閉体３の室内側の空間と通気路７との間に設けられる。通気路７は、隙間５４を介して、開閉体３の室内側の空間に繋がる。縦突出部材５０と開閉体３の間の隙間５４により、通気路７を通る空気の流通が阻害されず、建具１による通気が円滑に行われる。 In the state where the opening / closing body 3 is closed, the vertical protruding member 50 is arranged along the vertical edge portion 3C of the opening / closing body 3 and forms a gap 54 with the opening / closing body 3. The gap 54 is provided between the space on the indoor side of the opening / closing body 3 and the ventilation path 7. The ventilation path 7 is connected to the space on the indoor side of the opening / closing body 3 via the gap 54. The gap 54 between the vertical protruding member 50 and the opening / closing body 3 does not hinder the flow of air through the ventilation path 7, and allows the fitting 1 to smoothly ventilate the air.

縦突出部材５０は、通気路７を遮蔽する遮蔽部材（目隠し）である。縦突出部材５０を縦枠６の見込み方向の一方側（室内側）からみたときに、縦突出部材５０が通気路７に重なり、通気路７が縦突出部材５０により遮蔽される。また、通気路７を縦枠６の見込み方向の他方側（室外側）からみたときに、縦突出部材５０により、開閉体３の室内側の空間が隠される。縦突出部材５０は、通気路７の長手方向の全体にわたって設けられて、通気路７の全体を遮蔽する。縦突出部材５０により、通気路７を通して建具１の室内側が視認されるのが防止される。 The vertical protruding member 50 is a shielding member (blindfold) that shields the ventilation path 7. When the vertical projecting member 50 is viewed from one side (inside the room) of the vertical frame 6 in the prospective direction, the vertical projecting member 50 overlaps with the ventilation path 7, and the ventilation path 7 is shielded by the vertical projecting member 50. Further, when the ventilation path 7 is viewed from the other side (outside of the room) of the vertical frame 6 in the prospective direction, the space on the indoor side of the opening / closing body 3 is hidden by the vertical protruding member 50. The vertical protruding member 50 is provided over the entire length of the ventilation passage 7 in the longitudinal direction, and shields the entire ventilation passage 7. The vertical protruding member 50 prevents the indoor side of the fitting 1 from being visually recognized through the ventilation path 7.

開閉体３（図２参照）は、開き時に、縦枠６の見込み方向の他方側（室外側）に突出して折れ曲がり、閉じ時に、縦枠６の見込み方向の一方側（室内側）に向かって折れ曲がりを解消する。第２障子２１の縦框３４側では、開閉体３が閉じた状態で、通気路７が形成されて、縦突出部材５０により通気路７が遮蔽される。これに対し、第１障子２０の縦框３４側では、開閉体３が閉じた状態、及び、開閉体３が開いた状態で、通気路７が形成されて、縦突出部材５０により通気路７が遮蔽される。 The opening / closing body 3 (see FIG. 2) projects and bends to the other side (outside of the room) of the vertical frame 6 in the prospective direction of the vertical frame 6 when opened, and heads toward one side (inside of the room) of the vertical frame 6 in the prospective direction of the vertical frame 6 when closed. Eliminates bending. On the vertical frame 34 side of the second shoji 21, the ventilation passage 7 is formed with the opening / closing body 3 closed, and the ventilation member 7 is shielded by the vertical protruding member 50. On the other hand, on the side of the vertical frame 34 of the first shoji 20, the ventilation passage 7 is formed with the opening / closing body 3 closed and with the opening / closing body 3 open, and the ventilation passage 7 is formed by the vertical protruding member 50. Is shielded.

枠体２（図１参照）の枠組み前に、枠４〜６は、それぞれの長手方向に直交する方向に切断されて、所定長さに形成される。これにより、各長手方向に直交する両端部が枠４〜６に形成される。続いて、上枠４と下枠５が、一対の縦枠６の端部の間に配置されて、一対の縦枠６に組み合わされる。これにより、枠４〜６が端部同士を接触させた状態で方形状に組み合わされて、枠体２が枠組みされる。 Before the frame of the frame body 2 (see FIG. 1), the frames 4 to 6 are cut in a direction orthogonal to their respective longitudinal directions to have a predetermined length. As a result, both end portions orthogonal to each longitudinal direction are formed in the frames 4-6. Subsequently, the upper frame 4 and the lower frame 5 are arranged between the ends of the pair of vertical frames 6 and combined with the pair of vertical frames 6. As a result, the frames 4 to 6 are combined in a rectangular shape with their ends in contact with each other, and the frame body 2 is framed.

以上説明した建具１では、通気路７により、建具１の一方側と他方側（ここでは、室内側と室外側）との通気が可能になるとともに、縦突出部材５０により、建具１の通気路７を通した視認を防止することができる。また、通気路７の形成と視認の防止を簡単に実現でき、建具１の構造が複雑になるのを抑制することができる。 In the fitting 1 described above, the ventilation passage 7 enables ventilation between one side and the other side of the fitting 1 (here, the indoor side and the outdoor side), and the vertical projecting member 50 allows the ventilation passage of the fitting 1 to flow. The visual recognition through 7 can be prevented. Further, the formation of the ventilation passage 7 and the prevention of visual recognition can be easily realized, and the structure of the fitting 1 can be prevented from becoming complicated.

内周面部６Ａを縦枠６の見込み方向に沿って形成するため、建具１の有効開口を確保することができる。縦枠６への衝突も抑制できるため、縦枠６の開閉体３側における安全性を向上させることができる。内周面部６Ａに溝状に形成された取付部６Ｃに縦突出部材５０を取り付けており、縦枠６の構造を単純にしつつ、縦突出部材５０を縦枠６に容易に取り付けることができる。また、縦枠６の内周面部６Ａは、開口部２Ａの内方側に突出する部分のない平坦な形状に形成される。そのため、枠４〜６の端部を切断するだけで、枠４〜７を組み合わせることができる。従って、枠４〜６の端部の構造を含む建具１の構造が複雑になるのを抑制することができる。 Since the inner peripheral surface portion 6A is formed along the prospective direction of the vertical frame 6, the effective opening of the fitting 1 can be secured. Since the collision with the vertical frame 6 can be suppressed, the safety of the vertical frame 6 on the opening / closing body 3 side can be improved. The vertical protrusion member 50 is attached to the attachment portion 6C formed in the inner peripheral surface portion 6A in a groove shape, and the vertical protrusion member 50 can be easily attached to the vertical frame 6 while simplifying the structure of the vertical frame 6. Further, the inner peripheral surface portion 6A of the vertical frame 6 is formed in a flat shape without a portion protruding inward of the opening 2A. Therefore, the frames 4 to 7 can be combined by simply cutting the ends of the frames 4 to 6. Therefore, it is possible to prevent the structure of the fitting 1 including the structures of the ends of the frames 4 to 6 from becoming complicated.

取付部６Ｃが内周面部６Ａの一方側部（ここでは、室内側部）に形成されて、縦突出部材５０が内周面部６Ａの室内側で突出する。そのため、縦突出部材５０を開閉体３の縦縁部３Ｃに対して室内側に確実に配置することができる。開閉体３が室外側に突出して折れ曲がるため、開閉体３の開閉時に、開閉体３が縦突出部材５０に接触するのが防止される。これに伴い、開閉体３を円滑に開閉することができる。 The attachment portion 6C is formed on one side portion (here, the indoor side portion) of the inner peripheral surface portion 6A, and the vertical protruding member 50 protrudes on the indoor side of the inner peripheral surface portion 6A. Therefore, the vertical protruding member 50 can be reliably arranged on the indoor side with respect to the vertical edge portion 3C of the opening / closing body 3. Since the opening / closing body 3 projects outward and is bent, the opening / closing body 3 is prevented from contacting the vertical protruding member 50 when the opening / closing body 3 is opened / closed. Accordingly, the opening / closing body 3 can be opened / closed smoothly.

上枠４の気密材４０と同様の気密材が縦突出部材５０として利用され、下枠５の気密材４１と同様の気密材が下突出部材４２、４３として利用される。気密材４０、４１、縦突出部材５０、及び、下突出部材４２、４３は、軟質部材であり、弾性変形可能な軟質材（例えば、軟質樹脂、ゴム）で形成される。そのため、人が縦突出部材５０と下突出部材４２、４３に接触したときに、縦突出部材５０と下突出部材４２、４３が柔軟に変形する。これより、建具１の安全性をより向上させることができる。 An airtight material similar to the airtight material 40 of the upper frame 4 is used as the vertical protruding member 50, and an airtight material similar to the airtight material 41 of the lower frame 5 is used as the lower protruding members 42 and 43. The airtight members 40 and 41, the vertical protruding member 50, and the lower protruding members 42 and 43 are soft members, and are formed of elastically deformable soft materials (for example, soft resin and rubber). Therefore, when a person contacts the vertical protruding member 50 and the lower protruding members 42 and 43, the vertical protruding member 50 and the lower protruding members 42 and 43 are flexibly deformed. As a result, the safety of the fitting 1 can be further improved.

下突出部材４２、４３により、開閉体３の下側の部材（例えば、下枠５、床）と開閉体３との間に足の指が挟まれるのを抑制することができる。また、開閉体３が室内側に向かって折れ曲がろうとするときには、第１下突出部材４２が下枠５の気密材４１に接触して、開閉体３が停止する。第１下突出部材４２が気密材４１を乗り越えて気密材４１の室内側に移動したときには、第２下突出部材４３が気密材４１に接触して、開閉体３が停止する。これにより、開閉体３の室内側への移動（逆折れ曲がり）を防止することができる。下突出部材４２、４３が気密材４１乗り越えて気密材４１の室内側に移動したときには、下突出部材４２、４３と気密材４１を変形させつつ、下突出部材４２、４３を気密材４１の室外側に容易に復帰させることができる。その結果、建具１の室内側に人が閉じ込められるのを防止することができる。 The lower protruding members 42 and 43 can prevent the toes from being caught between the lower member of the opening / closing body 3 (for example, the lower frame 5, the floor) and the opening / closing body 3. Further, when the opening / closing body 3 is about to bend toward the indoor side, the first lower protruding member 42 contacts the airtight material 41 of the lower frame 5, and the opening / closing body 3 stops. When the first lower projecting member 42 moves over the airtight material 41 and moves to the indoor side of the airtight material 41, the second lower projecting member 43 contacts the airtight material 41 and the opening / closing body 3 stops. Accordingly, it is possible to prevent the opening / closing body 3 from moving to the indoor side (reverse bending). When the lower projecting members 42 and 43 move over the airtight material 41 and move to the indoor side of the airtight material 41, the lower projecting members 42 and 43 and the airtight material 41 are deformed, and the lower projecting members 42 and 43 are moved to the chamber of the airtight material 41. It can be easily returned to the outside. As a result, it is possible to prevent a person from being trapped inside the fitting 1 inside the room.
