Description

本発明は、枠体に対して障子がスライド可能に配設された建具に関するもので、特に、枠体の上枠部材に設けたガイドヒレ部を障子のガイド溝に収容させた状態で摺動片の摺動面に摺接させることにより、障子の上端部を枠体に対してスライド可能に支持させた建具に関する。   The present invention relates to a joinery in which a shoji is slidably arranged with respect to a frame, and in particular, a sliding piece in a state where a guide fin portion provided on an upper frame member of the frame is accommodated in a guide groove of the shoji. It is related with the fitting which supported the upper end part of the shoji so that it could slide with respect to a frame by making it slide-contact with.

引き違い窓や片引き窓等のように枠体に対して障子がスライド可能に配設された建具では、通常、枠体の上枠部材にガイドヒレ部が設けられ、かつ障子の上端部にガイド溝が設けられている。ガイドヒレ部は、上枠部材の見込み面から下方に向けて突出した板状を成す部分であり、上枠部材の長手方向に沿って設けられている。ガイド溝は、上框部材の上面においてガイドヒレ部に対向する部位に形成されたものである。このガイド溝は、ガイドヒレ部の板厚よりも大きな幅を有しており、障子の一方の端部に位置する縦框部材の上端部から上框部材を経て他方の端部に位置する縦框部材の上端部にわたって形成されている。ガイド溝の長手方向両端部には、それぞれ摺動片が配設されている。摺動片は、ガイドヒレ部に対して滑らかに摺動することのできる材質、例えば樹脂材によって成形されたもので、個々の縦框部材の端部に取り付けられている。それぞれの摺動片においてガイド溝に対応する部位には、摺動溝が設けられている。摺動溝は、一対の摺動面の間に構成された狭幅の空所であり、ガイドヒレ部を摺動可能に収容することのできる幅に形成されている。   In fittings such as sliding windows and single-sided windows where the shoji is slidable with respect to the frame, a guide fin is usually provided on the upper frame member of the frame, and a guide groove is formed at the upper end of the shoji. Is provided. The guide fin portion is a plate-like portion protruding downward from the prospective surface of the upper frame member, and is provided along the longitudinal direction of the upper frame member. The guide groove is formed in a portion facing the guide fin portion on the upper surface of the upper collar member. The guide groove has a width larger than the thickness of the guide fin portion, and the guide rod located at the other end portion through the upper flange member from the upper end portion of the longitudinal member located at one end portion of the shoji. It is formed over the upper end of the member. Sliding pieces are disposed at both ends in the longitudinal direction of the guide groove. The sliding piece is formed of a material that can slide smoothly with respect to the guide fin portion, for example, a resin material, and is attached to the end portion of each vertical rod member. A sliding groove is provided in a portion corresponding to the guide groove in each sliding piece. The sliding groove is a narrow space formed between a pair of sliding surfaces, and is formed to have a width that can slidably accommodate the guide fin portion.

この種の建具では、ガイドヒレ部が上框部材のガイド溝に配置される状態で障子を枠体に建て込めば、摺動片の摺動溝にガイドヒレ部が摺動可能に収容されることになり、一対の摺動面によって枠体に対する障子の見込み方向に沿った位置が規定されるとともに、枠体に対して障子の上端部がスライド可能に案内される（例えば、特許文献１及び特許文献２参照）。   In this type of joinery, if the shoji is built in the frame in a state where the guide fin portion is disposed in the guide groove of the upper collar member, the guide fin portion is slidably accommodated in the slide groove of the sliding piece. The position along the prospective direction of the shoji with respect to the frame is defined by the pair of sliding surfaces, and the upper end of the shoji is slidably guided with respect to the frame (for example, Patent Literature 1 and Patent Literature 1). 2).

ところで、上述した建具では、上枠部材と障子との間がガイドヒレ部と摺動片とによって支持されているだけである。このため、障子に大きな風荷重が加えられた場合には、この風荷重が長手方向両端部の摺動片のみを介してガイドヒレ部に伝えられることになる。従って、大きな風荷重を受けた場合には、摺動片を介して集中的に加えられる応力によりガイドヒレ部に変形等の損傷が招来され、障子のスライド操作性に大きな影響を及ぼすおそれがある。昨今においては、ビルが超高層化する傾向にあり、高層化するに従って建具に加えられる風荷重も増大するため、上述した問題が一層顕著となる。   By the way, in the joinery described above, the space between the upper frame member and the shoji is only supported by the guide fin portion and the sliding piece. For this reason, when a large wind load is applied to the shoji, this wind load is transmitted to the guide fin portion only through the sliding pieces at both ends in the longitudinal direction. Therefore, when a large wind load is received, the guide fin portion is damaged due to stress applied intensively through the sliding piece, which may greatly affect the sliding operability of the shoji. In recent years, buildings tend to be super-high, and the wind load applied to the joinery increases as the building becomes taller, so that the above-described problem becomes more prominent.

こうした問題は、例えば摺動片を上框部材の部分にも配設する等して、ガイドヒレ部との接触面積を増大させることが考えられる。しかしながら、摺動片を多数設けた場合には、摺動片の数に応じて障子をスライドさせる際の摺動抵抗が増大するため、障子のスライド操作性を損なうおそれがある。   Such a problem can be considered to increase the contact area with the guide fin portion, for example, by disposing the sliding piece also on the upper flange member. However, when a large number of sliding pieces are provided, the sliding resistance when sliding the shoji is increased according to the number of sliding pieces, there is a possibility that the sliding operability of the shoji is impaired.

本発明は、上記実情に鑑みて、障子のスライド操作性を損なうことなく、大きな風荷重に耐えることのできる建具を提供することを目的とする。   An object of this invention is to provide the fitting which can endure a big wind load, without impairing the sliding operativity of a shoji in view of the said situation.

上記目的を達成するため、本発明に係る建具は、一対の摺動面の間に摺動溝が構成された摺動片を、障子の上端部に設けたガイド溝の長手方向両端部に配設し、枠体の上枠部材に設けたガイドヒレ部を前記ガイド溝に収容させた状態で前記摺動片の摺動面に摺接させることにより、前記障子の上端部を前記枠体に対してスライド可能に支持させた建具であって、前記障子のガイド溝は、室外側及び室内側に位置する部分にそれぞれガイド面を有したものであり、前記ガイド面のいずれか一方には、前記各々の摺動片の間に位置する部分に、前記摺動片の摺動面よりも前記ガイドヒレ部から離隔する一方、前記ガイドヒレ部との間の距離が他方のガイド面と前記ガイドヒレ部との間の距離よりも小さくなる位置に支持面を設けたことを特徴とする。   In order to achieve the above object, the joinery according to the present invention has sliding pieces, each having a sliding groove between a pair of sliding surfaces, arranged at both ends in the longitudinal direction of the guide groove provided at the upper end of the shoji. The upper end portion of the shoji is moved with respect to the frame body by slidingly contacting the sliding surface of the sliding piece with the guide fin portion provided on the upper frame member of the frame body being accommodated in the guide groove. The sliding door guide groove has a guide surface at each of the portions located on the outdoor side and the indoor side, and either one of the guide surfaces has the above-mentioned guide groove. While the distance between the guide fin portion and the guide fin portion is greater than the slide surface of the slide piece, the distance between the guide fin portion and the guide fin portion is greater than the slide surface of the slide piece. It is characterized by providing a support surface at a position smaller than the distance between .

この発明によれば、障子が大きな風荷重を受けた場合、摺動片の間に設けた支持面がガイドヒレ部に当接するため、風荷重が集中的にガイドヒレ部に加えられる事態を防止することができ、ガイドヒレ部に変形等の損傷を招来するおそれがなくなる。   According to the present invention, when the shoji is subjected to a large wind load, the support surface provided between the sliding pieces comes into contact with the guide fin portion, so that it is possible to prevent a situation where the wind load is intensively applied to the guide fin portion. This eliminates the possibility of causing damage such as deformation to the guide fin portion.

また本発明は、上述した建具において、前記支持面は、前記一方のガイド面において前記各々の摺動片の間に位置する部分の全長にわたって設けたことを特徴とする。   In the joinery described above, the present invention is characterized in that the support surface is provided over the entire length of the portion located between the sliding pieces on the one guide surface.

この発明によれば、様々な大きさの障子を構成した場合にも、風荷重によって框部材に生じる応力を個別に計算して補強部品を必要点数用意しなければならないといった煩雑な作業を行うことなく、容易に、かつ確実に風荷重を分散させてガイドヒレ部に伝達させることができる。   According to the present invention, even when various sizes of shojis are configured, it is necessary to separately calculate the stress generated in the saddle member due to the wind load and prepare a necessary number of reinforcing parts. However, the wind load can be easily and reliably distributed to the guide fin portion.

また本発明は、上述した建具において、前記支持面は、前記一方のガイド面と前記ガイドヒレ部との間に支持部材を取り付けることによって構成したことを特徴とする。   In the joinery described above, the present invention is characterized in that the support surface is configured by attaching a support member between the one guide surface and the guide fin portion.

この発明によれば、支持部材を取り付けるか否かにより、風荷重が大きい場所に設置する障子と、風荷重が小さい場所に設置する障子とを共用することができる。   According to this invention, the shoji installed in a place with a large wind load and the shoji installed in a place with a small wind load can be shared depending on whether or not the support member is attached.

また本発明は、上述した建具において、前記支持面において前記ガイドヒレ部に対向する部位に複数の支持突起を設けたことを特徴とする。   In the joinery described above, the present invention is characterized in that a plurality of support protrusions are provided on a portion of the support surface facing the guide fin portion.

この発明によれば、障子をスライドさせる際に障子が支持面に接触してしまった場合の接触面積を減少させることができ、スライド操作性に影響を与えるおそれがない。   According to the present invention, the contact area when the shoji comes into contact with the support surface when sliding the shoji can be reduced, and there is no possibility of affecting the slide operability.

また本発明は、上述した建具において、前記障子は、一対の縦框部材の上端部間に前記上框部材を配設したものであり、それぞれの縦框部材に前記摺動片を取り付けるとともに、前記上框部材の全長にわたる部位に前記支持面を設けたことを特徴とする。   Moreover, the present invention is the above-mentioned joinery, wherein the shoji is provided with the upper eaves member between upper ends of a pair of eaves members, and the sliding piece is attached to each eaves member, The support surface is provided at a portion extending over the entire length of the upper collar member.

この発明によれば、様々な大きさの障子を構成した場合にも、風荷重によって框部材に生じる応力を個別に計算して補強部品を必要点数用意しなければならないといった煩雑な作業を行うことなく、容易に、かつ確実に風荷重を分散させてガイドヒレ部に伝達させることができる。   According to the present invention, even when various sizes of shojis are configured, it is necessary to separately calculate the stress generated in the saddle member due to the wind load and prepare a necessary number of reinforcing parts. However, the wind load can be easily and reliably distributed to the guide fin portion.

本発明によれば、障子が大きな風荷重を受けた場合、各々の摺動片の間に設けた支持面がガイドヒレ部に当接するため、風荷重が集中的にガイドヒレ部に加えられる事態を防止することができる。従って、ガイドヒレ部に変形等の損傷を招来するおそれがなくなり、障子をスライドさせる際の操作性を良好に維持することが可能となる。   According to the present invention, when the shoji is subjected to a large wind load, the support surface provided between the sliding pieces abuts against the guide fin portion, thereby preventing a situation where the wind load is concentrated on the guide fin portion. can do. Therefore, there is no possibility of causing damage such as deformation to the guide fin portion, and it is possible to maintain good operability when sliding the shoji.

The finding wall portion 42 is a flat plate-like portion that protrudes at a right angle upward from an edge portion located on the outdoor side of the prospective wall portion 41. The protruding dimension of the finding wall portion 42 from the prospective wall portion 41 is configured to be smaller than the distance from the base portion 22a of the upper collar member 22 to the second rib portion 22d. The support wall 43 is a flat plate portion that extends from the protruding end of the find wall 42 so as to be continuous with the find wall 42. As is clear from FIG. 1, the support wall portion 43 is configured to be offset toward the indoor side with respect to the finding wall portion 42. The offset amount of the support wall portion 43 is such that the distance from the surface facing the outdoor side of the finding wall portion 42 to the plane facing the indoor side of the support wall portion 43 (hereinafter referred to as “support surface 43a”) is from the outer guide surface 22fo. The sliding piece 30 is configured to be smaller than the distance to the sliding surface 32 located on the outdoor side. The engaging wall portion 44 protrudes in a direction perpendicular to the surface facing the outdoor side of the support wall portion 43 and then bends so as to become a right angle upward. The distance from the engagement wall portion 44 to the prospective wall portion 41 is smaller than the distance from the base portion 22a to the first rib portion 22c in the upper collar member 22, and larger than the distance from the base portion 22a to the second rib portion 22d. It is constituted as follows.

上記のように構成した支持部材４０は、障子２０を組み立てる際に予め上框部材２２の端面から挿入することにより、障子２０から脱落することなく、上框部材２２に装着することができる。すなわち、見込み壁部４１を上框部材２２の基部２２ａと第３リブ部２２ｅとの間に挿入するとともに、係合壁部４４を第１リブ部２２ｃと第２リブ部２２ｄとの間に挿入すれば、上框部材２２に対する支持部材４０の長手方向に沿った相対移動が許容される一方、見付け方向及び見込み方向に沿った移動が規制されるため、上框部材２２に対して脱落することなく支持部材４０を装着することが可能となる。上框部材２２の両端部に縦框部材２４が取り付けられた後、各縦框部材２４の上端部にそれぞれ摺動片３０を装着すれば、これらの摺動片３０に当接することによって上框部材２２に対する支持部材４０の長手方向に沿った相対移動も規制された状態となる。   The support member 40 configured as described above can be attached to the upper collar member 22 without dropping from the shoji 20 by inserting it from the end face of the upper collar member 22 in advance when assembling the shoji 20. That is, the prospective wall portion 41 is inserted between the base portion 22a of the upper collar member 22 and the third rib portion 22e, and the engagement wall portion 44 is inserted between the first rib portion 22c and the second rib portion 22d. Then, while the relative movement along the longitudinal direction of the support member 40 with respect to the upper collar member 22 is allowed, the movement along the finding direction and the prospective direction is restricted, so that the upper collar member 22 falls off. It is possible to mount the support member 40 without any problem. After the vertical hook members 24 are attached to both ends of the upper hook member 22, if the sliding pieces 30 are respectively attached to the upper end portions of the vertical hook members 24, the upper hook members 22 are brought into contact with the sliding pieces 30. The relative movement along the longitudinal direction of the support member 40 with respect to the member 22 is also restricted.

上框部材２２に支持部材４０を装着した障子２０は、図２中のクロスハッチングで示すように、上框部材２２の外側ガイド面２２ｆｏにおいて縦框部材２４の上端部に装着した摺動片３０の相互間となる部分の全長に支持部材４０の支持壁部４３が位置することになる。支持壁部４３の支持面４３ａは、図１に示すように、摺動片３０の室外側に位置する摺動面３２よりもガイドヒレ部１１ｂから離隔した位置に配置されることになる。従って、この状態で障子２０を枠体１０に建て込めば、支持壁部４３の支持面４３ａと上枠部材１１のガイドヒレ部１１ｂとの間に隙間が確保されることになり、大きな操作力を要することなく障子２０をスライドさせることが可能となる。   As shown by the cross hatching in FIG. 2, the shoji 20 having the support member 40 attached to the upper collar member 22 has a sliding piece 30 attached to the upper end portion of the vertical collar member 24 on the outer guide surface 22fo of the upper collar member 22. The support wall portion 43 of the support member 40 is positioned over the entire length of the portion between the two. As shown in FIG. 1, the support surface 43 a of the support wall portion 43 is disposed at a position farther from the guide fin portion 11 b than the slide surface 32 positioned on the outdoor side of the slide piece 30. Therefore, if the shoji 20 is built in the frame 10 in this state, a gap is secured between the support surface 43a of the support wall 43 and the guide fin portion 11b of the upper frame member 11, and a large operating force is obtained. The shoji 20 can be slid without any need.

しかも、支持面４３ａとガイドヒレ部１１ｂとの間の距離は、ガイド溝２６の室内側に構成されるガイド面（以下、区別する場合に「内側ガイド面２２ｆｉ」という）とガイドヒレ部１１ｂとの間の距離に比較して小さい状態となる。従って、例えば、建具を超高層ビルの高層階に設置することによって障子２０に大きな風荷重が作用したとしても、上框部材２２が室内側にわずかに撓むことで支持部材４０の支持面４３ａがガイドヒレ部１１ｂに当接するため、風荷重が集中的にガイドヒレ部１１ｂに加えられる事態を防止することが可能となる。これにより、上記建具によれば、ガイドヒレ部１１ｂに変形等の損傷を招来するおそれがなくなり、常に障子２０をスライドさせる際の操作性を良好に維持することができるようになる。   Moreover, the distance between the support surface 43a and the guide fin portion 11b is between the guide surface (hereinafter referred to as “inner guide surface 22fi” when distinguished) and the guide fin portion 11b. It becomes a small state compared with the distance. Therefore, for example, even if a large wind load is applied to the shoji 20 by installing the joinery on the high floor of the skyscraper, the upper support member 22 slightly bends indoors to support the support surface 43a of the support member 40. Since it contacts the guide fin portion 11b, it is possible to prevent a situation in which wind loads are intensively applied to the guide fin portion 11b. Thereby, according to the said fitting, there is no possibility of causing damages such as deformation to the guide fin portion 11b, and the operability when sliding the shoji 20 can always be maintained well.

尚、上述した実施の形態では、ガイド溝２６において摺動片３０の間の全長にわたる部位に支持面４３ａを設けるようにしているため、サイズの異なる建具に対しても風荷重によって框部材に生じる応力を個別に計算して補強部品を必要点数用意しなければならないといった煩雑な作業を行うことなく、常に上述の作用効果を奏することが可能になる。しかしながら、本発明は必ずしも支持面４３ａを全長にわたって設ける必要はなく、例えば複数の支持面４３ａを等間隔に設けるようにしても構わない。   In the above-described embodiment, since the support surface 43a is provided in the portion of the guide groove 26 that extends over the entire length between the sliding pieces 30, it is also generated in the eaves member by wind load even for fittings having different sizes. It is possible to always obtain the above-described effects without performing a complicated operation of separately calculating the stress and preparing the necessary number of reinforcing parts. However, in the present invention, the support surface 43a is not necessarily provided over the entire length, and for example, a plurality of support surfaces 43a may be provided at equal intervals.

また、上述した実施の形態では、上框部材２２とは別体となる支持部材４０を装着することによって支持面４３ａを構成するようにしているため、既存の建具に対して適用することができるばかりでなく、支持部材４０を適宜着脱することにより、低層階に設置される建具のように、大きな風荷重を受けるおそれのない建具との間において上框部材２２を共用することが可能となる。しかしながら、本発明では、上框部材に一体に支持面を設けるようにしてももちろん構わない。   In the above-described embodiment, the support surface 43a is configured by mounting the support member 40, which is a separate body from the upper collar member 22, and therefore can be applied to existing joinery. In addition, by appropriately attaching and detaching the support member 40, the upper eaves member 22 can be shared with a joinery that is not likely to receive a large wind load, such as a joinery installed on a lower floor. . However, in the present invention, it goes without saying that a support surface may be provided integrally with the upper collar member.

さらに、上述した実施の形態では、支持面４３ａとして平坦に構成したものを例示しているが、本発明は必ずしもこれに限定されず、例えば、図４に示す変形例のように、見込み壁部１４１、見付け壁部１４２、支持壁部１４３及び係合壁部１４４を有した支持部材１４０の支持壁部１４３に複数の支持突起１４５を設けることによって支持面１４３ａを構成しても良い。複数の支持突起１４５を設ける場合には、個々の支持突起１４５の突出端がガイドヒレ部１１ｂと平行となる同一の平面上に位置するように構成することが好ましい。支持部材１４０に複数の支持突起１４５を設けることによって支持面１４３ａを構成した建具にあっても、障子２０に大きな風荷重が作用した場合には、上框部材２２が室内側にわずかに撓むことで支持部材１４０の支持面１４３ａがガイドヒレ部１１ｂに当接するため、風荷重が集中的にガイドヒレ部１１ｂに加えられる事態を防止することが可能となる。これにより、上記建具によれば、ガイドヒレ部１１ｂに変形等の損傷を招来するおそれがなくなり、常に障子２０をスライドさせる際の操作性を良好に維持することができるようになる。しかも、障子２０をスライドさせる際に万が一、ガイドヒレ部１１ｂに支持突起１４５が接触した場合にも、平坦に構成された支持面に比べて、ガイドヒレ部１１ｂとの接触面積が小さくなるため、操作力に大きな影響を与えるおそれがない。尚、図４に示す変形例において実施の形態と同様の構成については同一の符号を付して詳細説明を省略している。   Further, in the above-described embodiment, the support surface 43a is illustrated as being flat, but the present invention is not necessarily limited to this. For example, as in the modification shown in FIG. The support surface 143a may be configured by providing a plurality of support protrusions 145 on the support wall portion 143 of the support member 140 having the 141, the finding wall portion 142, the support wall portion 143, and the engagement wall portion 144. In the case where a plurality of support protrusions 145 are provided, it is preferable that the protruding ends of the individual support protrusions 145 be positioned on the same plane parallel to the guide fin portion 11b. Even in a fitting in which the support surface 143a is configured by providing a plurality of support protrusions 145 on the support member 140, when a large wind load acts on the shoji 20, the upper collar member 22 slightly bends indoors. Thus, since the support surface 143a of the support member 140 contacts the guide fin portion 11b, it is possible to prevent a situation in which wind loads are intensively applied to the guide fin portion 11b. Thereby, according to the said fitting, there is no possibility of causing damages such as deformation to the guide fin portion 11b, and the operability when sliding the shoji 20 can always be maintained well. Moreover, even when the sliding screen 20 is slid, if the support protrusion 145 comes into contact with the guide fin portion 11b, the contact area with the guide fin portion 11b is smaller than that of the flat support surface. There is no risk of significant impact on In the modification shown in FIG. 4, the same reference numerals are given to the same components as those in the embodiment, and the detailed description is omitted.

またさらに、上述した実施の形態及び変形例では、いずれも室外側に位置するガイド面にのみ支持面を設けるようにしているが、本発明はこれに限定されない。例えば、負圧を受けるような状況下においては、室内側に位置するガイド面にのみ支持面を設けるようにしても構わない。   Furthermore, in the above-described embodiments and modifications, the support surface is provided only on the guide surface located on the outdoor side, but the present invention is not limited to this. For example, in a situation where negative pressure is applied, the support surface may be provided only on the guide surface located on the indoor side.
