Description
本発明は、建物に取り付けられる枠体に丁番を介して回動自在に取り付けられる戸体を有する建具に関する。 The present invention relates to a fixture having a door body that is rotatably attached via hinges to a frame that is attached to a building.
従来から、建物の開口部に設けられた枠体の内側に配置される戸体が、丁番により開閉可能に枠体に連結されている建具は知られている（例えば、特許文献１参照）。この建具は、丁番を構成し上方に向かって突出する軸部を有する枠体側羽根板が、枠体を構成する縦枠の見込み面に直接取り付けられている。 Fittings have been known in the past in which a door body, placed inside a frame installed in an opening in a building, is connected to the frame by a hinge so that it can be opened and closed (see, for example, Patent Document 1). In this fitting, the frame-side slats that form the hinge and have an axis that protrudes upward are attached directly to the visible surface of the vertical frame that makes up the frame.
上記従来の建具は、丁番を構成し上方に向かって突出する軸部を有する枠体側羽根板が、縦枠の見込み面に直接取り付けられているので、戸体を閉じた時や戸体を開いた状態で大きな外力による衝撃が作用すると、戸体が支持されている枠体側羽根板が縦枠の見込み面を面外方向に押圧する、或いは、面内方向において回転するモーメントが作用して、縦枠が変形してしまう虞があるという課題があった。 In the above-mentioned conventional building fixtures, the frame-side slats, which form hinges and have an axis that protrudes upward, are attached directly to the visible surface of the vertical frame. Therefore, if a large external force acts on the door body when it is closed or open, the frame-side slats that support the door body may press against the visible surface of the vertical frame in an out-of-plane direction, or a moment of rotation may act in an in-plane direction, potentially causing deformation of the vertical frame.
本発明は、かかる課題に鑑みてなされたものであり、その目的とするところは、戸体から丁番を介して伝達される外力が作用しても縦枠が変形しにくい建具を提供することにある。 The present invention was made in consideration of these issues, and its purpose is to provide a fixture whose vertical frame is less likely to deform even when external forces are applied from the door body via the hinges.
かかる目的を達成するための主たる発明は、建物に取り付けられる枠体と、前記枠体が有する縦枠に丁番を介して回動自在に取り付けられる戸体と、を有する建具であって、前記丁番は、前記縦枠において見込み面を形成する見込み面部に固定される枠側板部と、前記枠側板部の室外側の端に設けられ上方に延びる回動軸を有する軸部と、を有する枠側部材と、前記戸体に固定されて前記回動軸と係合して回動する戸体側部材と、を有し、前記枠側板部は、前記見込み面部に、上下方向に間隔を空けて配置される複数の固定具により固定される金属製の固定板とともに当該見込み面部を挟持して前記縦枠に固定され、前記複数の固定具のうちの少なくとも１つの前記固定具の位置は、前記軸部の先端と同じ高さ、または、前記軸部の先端よりも高いことを特徴とする建具である。
本発明の他の特徴については、本明細書及び添付図面の記載により明らかにする。
The main invention for achieving this purpose is a fixture comprising a frame body to be attached to a building, and a door body that is rotatably attached to a vertical frame of the frame body via a hinge, wherein the hinge comprises a frame side member having a frame side panel portion fixed to a projected surface portion that forms a projected surface in the vertical frame, and an axle portion that is provided at the outside end of the frame side panel portion and has a rotation axis that extends upward, and a door body side member that is fixed to the door body and engages with the rotation axis to rotate, wherein the frame side panel portion is fixed to the vertical frame by clamping the projected surface portion together with a metal fixing plate that is fixed to the projected surface portion by a plurality of fixing devices that are arranged at intervals in the vertical direction, and the position of at least one of the plurality of fixing devices is at the same height as the tip of the axle portion or higher than the tip of the axle portion.
Other features of the present invention will become apparent from the description of this specification and the accompanying drawings.
本発明によれば、戸体から丁番を介して伝達される外力が作用しても縦枠が変形しにくい建具を提供することが可能となる。 This invention makes it possible to provide a fixture whose vertical frame is less likely to deform even when external forces are transmitted from the door body via the hinge.
以下、本発明の一実施形態に係る建具について図面を参照して説明する。
本実施形態に係る建具１の一例として、図１に示すように、建物の躯体に固定され開口１ａを形成する枠体２と、枠体２に丁番４を介して開閉自在に取り付けられている戸体としての扉３を有する建具１を例に挙げて説明する。
Hereinafter, a fitting according to one embodiment of the present invention will be described with reference to the drawings.
As an example of a fixture 1 according to this embodiment, as shown in Figure 1, we will explain the fixture 1 having a frame body 2 fixed to the building frame and forming an opening 1a, and a door 3 as a door body attached to the frame body 2 via hinges 4 so as to be able to be opened and closed freely.
本実施形態の建具１は、図１に示すように、扉３が、枠体２を構成する左側の縦枠２０に丁番４を介して開閉自在に取り付けられている。以下の説明においては、建物等に取り付けられた状態の建具１を、室内側から見たときに、上下となる方向を上下方向、左右となる方向を左右方向、室内外方向である奥行き方向を見込み方向として示す。また、見込み方向において、扉３が開く際に移動する側を室外側、反対側であって、戸当たりが設けられている側を室内側とし、また、枠体２の内側となる開口１ａ側を内周側、枠体２において開口１ａとは反対の外側を外周側として説明する。 As shown in Figure 1, the fitting 1 of this embodiment has a door 3 attached via hinges 4 to the left-hand vertical frame 20 that constitutes the frame 2 so that it can be opened and closed freely. In the following explanation, when the fitting 1 attached to a building or the like is viewed from the inside of a room, the up-down direction is referred to as the up-down direction, the left-right direction is referred to as the left-right direction, and the depth direction, which is the direction from inside to outside, is referred to as the front direction. In addition, in the front direction, the side to which the door 3 moves when opening is referred to as the outside, and the opposite side, where a door stop is provided, is referred to as the inside. Furthermore, the side of the opening 1a on the inside of the frame 2 is referred to as the inner periphery, and the outside of the frame 2 opposite the opening 1a is referred to as the outer periphery.
縦枠２０は、図２に示すように、見込み方向における室外側に配置されるアルミニウム製の金属縦枠２１と、見込み方向における室内側に配置される合成樹脂製の樹脂縦枠２２とが係合されて接合された複合枠材である。また、金属縦枠２１及び樹脂縦枠２２は、いずれも上下方向（長手方向）を押し出し方向とする押し出し形材である。 As shown in Figure 2, the vertical frame 20 is a composite frame material formed by joining together a metal vertical frame 21 made of aluminum, which is positioned on the exterior side of the building in the projection direction, and a resin vertical frame 22 made of synthetic resin, which is positioned on the interior side of the building in the projection direction. Furthermore, both the metal vertical frame 21 and the resin vertical frame 22 are extruded shapes whose extrusion direction is in the vertical direction (longitudinal direction).
金属縦枠２１は、断面が見込み方向に長いほぼ矩形状をなし上下方向に貫通する見込み面２１ｂを有しており、扉３は、中空部２１ａを形成し、枠体２が形成する開口１ａ側となる内周側にて見込み面２１ｂを形成する見込み面部２１ｃに丁番４を介して開閉自在に取り付けられている。扉３は、上下方向に適宜間隔を空けて設けられている３つの丁番４により金属縦枠２１に取り付けられている。以下では、最も上に設けられている丁番４を例に挙げて説明するが、他の丁番４も同様である。 The metal vertical frame 21 has a generally rectangular cross section that is long in the projection direction and has a projection surface 21b that penetrates vertically. The door 3 forms a hollow portion 21a and is attached via hinges 4 to the projection surface portion 21c that forms the projection surface 21b on the inner periphery, which is the side of the opening 1a formed by the frame body 2, so that it can be opened and closed freely. The door 3 is attached to the metal vertical frame 21 with three hinges 4 that are appropriately spaced apart in the vertical direction. The following explanation uses the topmost hinge 4 as an example, but the other hinges 4 operate in the same way.
各丁番４は、図３に示すように、鉛直方向に延びる回動軸４０ａを備え金属縦枠２１に取り付けられる枠側部材４０と、扉３に取り付けられる扉側部材４１と、を有している。枠側部材４０は、見込み面部２１ｃの見込み面２１ｂと対面して当接される平板状をなす枠側板部４０ｂと、枠側板部４０ｂの室外側の端に設けられ、上方に延びる回動軸４０ａを有する軸部４０ｃと、を有している。枠側板部４０ｂには、金属縦枠２１に固定するための皿ビス６が挿通される、皿もみされた挿通孔４０ｅが設けられている。 As shown in Figure 3, each hinge 4 has a frame side member 40 that is attached to the vertical metal frame 21 and has a pivot shaft 40a extending vertically, and a door side member 41 that is attached to the door 3. The frame side member 40 has a flat frame side plate portion 40b that faces and abuts against the visible surface 21b of the visible surface portion 21c, and a shaft portion 40c that is provided at the outside edge of the frame side plate portion 40b and has the pivot shaft 40a extending upward. The frame side plate portion 40b has a countersunk insertion hole 40e through which a countersunk screw 6 is inserted to secure it to the vertical metal frame 21.
軸部４０ｃは、円柱状をなし枠側板部４０ｂと繋がる軸基部４０ｄと、軸基部４０ｄから上方に突出する回動軸４０ａとを有している。回動軸４０ａは、直径が軸基部４０ｄの直径より小さく形成されるとともに、軸基部４０ｄと同軸に形成されている。 The shaft portion 40c has a cylindrical shaft base 40d that connects to the frame side plate portion 40b, and a pivot shaft 40a that protrudes upward from the shaft base 40d. The pivot shaft 40a has a smaller diameter than the shaft base 40d and is coaxial with the shaft base 40d.
扉側部材４１は、扉３の側面３ａと対面して当接される平板状をなす扉側板部４１ａと、扉側板部４１ａの室外側の端に設けられ、枠側部材４０の回動軸４０ａが挿通される軸受け孔４１ｂを有する軸受け部４１ｃと、を有している。扉側板部４１ａには、扉３に固定するためのビスが挿通される挿通孔４１ｄが設けられている。 The door side member 41 has a flat door side plate portion 41a that faces and abuts against the side surface 3a of the door 3, and a bearing portion 41c that is provided at the outdoor end of the door side plate portion 41a and has a bearing hole 41b through which the pivot shaft 40a of the frame side member 40 is inserted. The door side plate portion 41a has an insertion hole 41d through which a screw is inserted to secure it to the door 3.
軸受け部４１ｃは、上端が閉塞された円筒状をなし扉側板部４１ａと繋がっており、軸受け孔４１ｂは、下端が解放されて上方に窪ませて設けられており、その内径は、回動軸４０ａの直径より僅かに大きく形成されている。また、軸受け孔４１ｂの深さは、回動軸４０ａにおける軸基部４０ｄからの上方への突出量より深く形成されている。 The bearing portion 41c is cylindrical with a closed upper end and connected to the door side panel portion 41a, while the bearing hole 41b is recessed upward with an open lower end, and its inner diameter is slightly larger than the diameter of the pivot shaft 40a. The depth of the bearing hole 41b is also greater than the amount of upward protrusion of the pivot shaft 40a from the shaft base 40d.
枠側部材４０と扉側部材４１とは、枠側部材４０の回動軸４０ａが、扉側部材４１の軸受け孔４１ｂに挿入されて、軸受け部４１ｃが軸基部４０ｄ上に載置されている。このとき、回動軸４０ａの上端４０ｇは、軸受け部４１ｃとは接触していない。 The frame side member 40 and the door side member 41 are arranged such that the pivot shaft 40a of the frame side member 40 is inserted into the bearing hole 41b of the door side member 41, and the bearing portion 41c rests on the shaft base 40d. At this time, the upper end 40g of the pivot shaft 40a is not in contact with the bearing portion 41c.
扉側部材４１が取り付けられた扉３は、扉側部材４１が回動軸４０ａ周りに回動することにより、枠側部材４０を介して縦枠２０に回動自在に支持されている。 The door 3 to which the door side member 41 is attached is rotatably supported on the vertical frame 20 via the frame side member 40 by the door side member 41 rotating around the rotation axis 40a.
扉側板部４１ａは、扉３の側面３ａに直接ビス止めされており、枠側板部４０ｂは、中空部２１ａ内に設けられ、見込み面部２１ｃに固定具としてのビス７により固定されている固定板５に、見込み面部２１ｃの挿通孔２１ｄに挿通される皿ビス６により固定されている。 The door side panel 41a is directly screwed to the side surface 3a of the door 3, and the frame side panel 40b is provided within the hollow portion 21a. It is fixed to a fixing plate 5, which is fixed to the projecting surface 21c with a screw 7 as a fixing device, by a countersunk screw 6 inserted into an insertion hole 21d in the projecting surface 21c.
固定板５は、例えば鋼製（溶融亜鉛メッキ鋼板）の長方形状をなす平板であり、長手方向が金属縦枠２１の長手方向に沿うように配置される。固定板５には、長手方向における両端部側に各々ビス７が螺合される２つのビス孔５ａと、長手方向における中央部に皿ビス６が螺合される４つのビス孔５ｂが設けられている。固定板５は、長手方向における中央を通る直線を軸に線対称となる形状をなしている。 The fixing plate 5 is a rectangular flat plate made of, for example, steel (hot-dip galvanized steel plate), and is positioned so that its longitudinal direction coincides with the longitudinal direction of the metal vertical frame 21. The fixing plate 5 has two screw holes 5a at both ends in the longitudinal direction, into which screws 7 are threaded, and four screw holes 5b in the longitudinal center, into which countersunk screws 6 are threaded. The fixing plate 5 is shaped to be line-symmetrical with respect to a straight line passing through the center in the longitudinal direction.
固定板５は、中空部２１ａ内にて見込み面部２１ｃと対面して当接され、見込み面部２１ｃに設けられている２つの挿通孔２１ｄに挿通するビス７が螺合されて取り付けられている。このとき、固定板５に設けられている４つのビス孔５ｂと、見込み面部２１ｃに設けられている４つの挿通孔２１ｅとは重なっている。 The fixing plate 5 is abutted against the visible surface 21c within the hollow portion 21a, and is attached by threading screws 7 into two insertion holes 21d provided in the visible surface 21c. At this time, the four screw holes 5b provided in the fixing plate 5 overlap with the four insertion holes 21e provided in the visible surface 21c.
枠側部材４０は、枠側板部４０ｂに設けられている４つの挿通孔４０ｅにそれぞれ挿通された皿ビス６が、見込み面部２１ｃの挿通孔２１ｅに挿通されて固定板５に設けられているビス孔５ｂに螺合されて金属縦枠２１に取り付けられている。すなわち、見込み面部２１ｃは、図２に示すように、固定板５と枠側板部４０ｂとに挟まれており、皿ビス６が螺合されて、固定板５と枠側板部４０ｂとが枠側板部４０ｂを挟持することにより、枠側部材４０が金属縦枠２１に取り付けられている。 The frame side member 40 is attached to the metal vertical frame 21 by inserting countersunk screws 6 into the four through holes 40e provided in the frame side plate portion 40b, which are then inserted into the through holes 21e in the projection surface portion 21c and screwed into the screw holes 5b provided in the fixing plate 5. That is, as shown in FIG. 2, the projection surface portion 21c is sandwiched between the fixing plate 5 and the frame side plate portion 40b, and the countersunk screws 6 are screwed in to sandwich the frame side plate portion 40b between the fixing plate 5 and the frame side plate portion 40b, thereby attaching the frame side member 40 to the metal vertical frame 21.
枠側部材４０が金属縦枠２１に取り付けられた状態では、図４に示すように、固定板５を枠側板部４０ｂに固定している上側のビス７は、枠側部材４０が有する回動軸４０ａの上端４０ｇよりも高い位置に配置されており、下側のビス７は、枠側部材４０が有する軸部４０ｃの下端４０ｈよりも低い位置に配置されている。また、固定板５の室内側の縁５ｃは、枠側板部４０ｂの室内側の縁４０ｆよりも室内側に位置している。 When the frame side member 40 is attached to the metal vertical frame 21, as shown in Figure 4, the upper screw 7 that secures the fixing plate 5 to the frame side panel portion 40b is positioned higher than the upper end 40g of the pivot shaft 40a of the frame side member 40, and the lower screw 7 is positioned lower than the lower end 40h of the shaft portion 40c of the frame side member 40. In addition, the interior-facing edge 5c of the fixing plate 5 is positioned closer to the interior than the interior-facing edge 40f of the frame side panel portion 40b.
本実施形態の建具１によれば、扉３を回動自在に取り付ける丁番４において、縦枠２０の見込み面部２１ｃに固定される枠側板部４０ｂは、金属製の固定板５とともに見込み面部２１ｃを挟持して皿ビス６により固定されているので、見込み面部２１ｃが固定板５に補強される。このため、扉３から丁番４を介して伝達される外力による見込み面部２１ｃの変形を抑制することが可能である。 In the fitting 1 of this embodiment, the hinge 4 that rotatably attaches the door 3 has a frame side panel 40b fixed to the projected surface 21c of the vertical frame 20. The frame side panel 40b is fixed to the projected surface 21c of the vertical frame 20 with a metal fixing plate 5, sandwiching the projected surface 21c between them, and is fixed with a countersunk head screw 6, so that the projected surface 21c is reinforced by the fixing plate 5. This makes it possible to suppress deformation of the projected surface 21c due to external forces transmitted from the door 3 via the hinge 4.
また、扉３から伝達される外力は、丁番４を介して枠体２に伝達される。このため、扉３の面内方向に作用するモーメントが生じると、回動軸４０ａと扉側部材４１との係合部を中心として枠側板部４０ｂに外力が作用する。このため、枠側板部４０ｂとともに見込み面部２１ｃを挟持している固定板５を見込み面部２１ｃに固定するビス７を、上下方向に間隔を空けて配置し、上側のビス７の位置を回動軸４０ａの上端４０ｇよりも高くすることにより、枠側板部４０ｂの面内方向に作用するモーメントに対しても見込み面部２１ｃの変形を抑制することが可能となる。このため、扉３から伝達される外力が作用しても縦枠２０が変形しにくい建具１を提供することが可能となる。 In addition, external forces transmitted from the door 3 are transmitted to the frame 2 via the hinges 4. Therefore, when a moment acting in the in-plane direction of the door 3 is generated, the external force acts on the frame side panel 40b, centered around the engagement point between the pivot shaft 40a and the door side member 41. For this reason, by arranging the screws 7 that secure the fixing plate 5, which clamps the projection surface 21c together with the frame side panel 40b, to the projection surface 21c at intervals in the vertical direction and positioning the upper screw 7 higher than the upper end 40g of the pivot shaft 40a, it is possible to suppress deformation of the projection surface 21c even when a moment acting in the in-plane direction of the frame side panel 40b is applied. This makes it possible to provide a fitting 1 in which the vertical frame 20 is resistant to deformation even when external forces transmitted from the door 3 are applied.
また、固定板５の室内側の縁５ｃは、取り付けられた丁番４の枠側板部４０ｂにおける室内側の縁４０ｆよりも室内側に位置するので、扉３に外力が作用して、枠側板部４０ｂの室内側の縁４０ｆが見込み面部２１ｃを固定板５側に押圧するように作用したとしても、見込み面部２１ｃが押し込まれるような変形が固定板５により規制される。このため、より変形しにくい縦枠２０を備えた建具１を提供することが可能となる。 In addition, the interior-facing edge 5c of the fixed plate 5 is located closer to the interior than the interior-facing edge 40f of the frame side panel 40b of the attached hinge 4. Therefore, even if an external force acts on the door 3 and the interior-facing edge 40f of the frame side panel 40b presses the projected surface 21c toward the fixed plate 5, the fixed plate 5 prevents deformation of the projected surface 21c. This makes it possible to provide a fitting 1 with a vertical frame 20 that is less likely to deform.
また、固定板５を見込み面部２１ｃに固定する２本のビス７のうちの少なくとも１つビス７の位置は、軸部４０ｃの下端４０ｈよりも低いので、丁番４の枠側板部４０ｂが固定される固定板５は、上下に広く間隔を空けた２本のビス７により固定される。このため、固定板５及び枠側板部４０ｂの面内方向における回転がより抑制されるので、扉３から伝達される外力による見込み面部２１ｃの変形をより抑制することが可能である。 Furthermore, at least one of the two screws 7 that secure the fixing plate 5 to the projection surface 21c is positioned lower than the lower end 40h of the shaft 40c, so the fixing plate 5 to which the frame side plate 40b of the hinge 4 is secured is secured by two screws 7 that are widely spaced apart vertically. This further reduces in-plane rotation of the fixing plate 5 and frame side plate 40b, making it possible to further reduce deformation of the projection surface 21c due to external forces transmitted from the door 3.
上記実施形態においては、固定板５を枠側板部４０ｂに固定している上側のビス７の中心が、回動軸４０ａの上端４０ｇより上に位置している例について説明したが、上側のビス７の位置は、回動軸４０ａの上端４０ｇと同じ高さ、または、回動軸４０ａの上端４０ｇよりも高い位置に設けられていれば構わない。また、上側のビス７の位置は、ビス７の中心ではなく、ビス７の頭部の下端が、回動軸４０ａの上端４０ｇと同じ高さ、または、回動軸４０ａの上端４０ｇよりも高い位置であっても構わない。 In the above embodiment, an example was described in which the center of the upper screw 7 that secures the fixed plate 5 to the frame side plate portion 40b is located above the upper end 40g of the pivot shaft 40a. However, the position of the upper screw 7 may be at the same height as or higher than the upper end 40g of the pivot shaft 40a. Furthermore, the position of the upper screw 7 may not be at the center of the screw 7, but may be such that the lower end of the head of the screw 7 is at the same height as or higher than the upper end 40g of the pivot shaft 40a.
上記実施形態においては、固定板５が２本のビス７により枠側板部４０ｂに固定されている例について説明したが、これに限るものではない。例えば、固定板５が３本以上のビス７により固定されており、それらのビス７のうち少なくとも１本が、回動軸４０ａの上端４０ｇよりも高い位置に配置されていれば構わない。このとき、複数のビス７のうち少なくとも１本が、軸部４０ｃの下端４０ｈよりも低い位置に配置されていることがより好ましい。 In the above embodiment, an example was described in which the fixing plate 5 is fixed to the frame side plate portion 40b with two screws 7, but this is not limited to this. For example, the fixing plate 5 may be fixed with three or more screws 7, with at least one of those screws 7 being positioned higher than the upper end 40g of the pivot shaft 40a. In this case, it is more preferable that at least one of the multiple screws 7 be positioned lower than the lower end 40h of the shaft portion 40c.
上記実施形態においては、扉３が丁番４を介して取り付けられる枠体２が、金属縦枠２１と樹脂縦枠２２とが係合されて接合された複合枠材が枠組みされている例について説明したが、枠体を構成する枠材は、複合枠材に限らず、金属或いは樹脂等の単一の部材で構成された枠体であっても構わない。 In the above embodiment, an example was described in which the frame body 2 to which the door 3 is attached via hinges 4 is made up of a composite frame material in which a metal vertical frame 21 and a resin vertical frame 22 are engaged and joined together. However, the frame material that makes up the frame body is not limited to a composite frame material, and it may also be a frame body made up of a single member such as metal or resin.
上記実施形態は、本発明の理解を容易にするためのものであり、本発明を限定して解釈するためのものではない。本発明は、その趣旨を逸脱することなく、変更、改良され得ると共に、本発明にはその等価物が含まれることはいうまでもない。
本実施形態には、少なくとも以下の発明が含まれる。
The above-described embodiments are provided to facilitate understanding of the present invention and are not intended to limit the present invention. The present invention may be modified or improved without departing from the spirit thereof, and the present invention includes equivalents thereof.
The present embodiment includes at least the following inventions.
建物に取り付けられる枠体と、前記枠体が有する縦枠に丁番を介して回動自在に取り付けられる戸体と、を有する建具であって、前記丁番は、前記縦枠において見込み面を形成する見込み面部に固定される枠側板部と、前記枠側板部の室外側の端に設けられ上方に延びる回動軸を有する軸部と、を有する枠側部材と、前記戸体に固定されて前記回動軸と係合して回動する戸体側部材と、を有し、前記枠側板部は、前記見込み面部に、上下方向に間隔を空けて配置される複数の固定具により固定される金属製の固定板とともに当該見込み面部を挟持して前記縦枠に固定され、前記複数の固定具のうちの少なくとも１つの前記固定具の位置は、前記軸部の先端と同じ高さ、または、前記軸部の先端よりも高いことを特徴とするである。 A fixture comprising a frame body attached to a building and a door body rotatably attached to a vertical frame of the frame body via a hinge. The hinge comprises a frame side member having a frame side panel fixed to a projecting surface portion of the vertical frame that forms the projecting surface, and an axle portion located at the outside edge of the frame side panel and having a pivot shaft extending upward; and a door body side member fixed to the door body and engaging with the pivot shaft to rotate. The frame side panel is fixed to the vertical frame by clamping the projecting surface portion together with a metal fixing plate fixed to the projecting surface portion by a plurality of fixing devices arranged at intervals in the vertical direction, and at least one of the fixing devices is positioned at the same height as or higher than the tip of the axle.
このような建具によれば、戸体を回動自在に取り付ける丁番において、縦枠の見込み面部に固定される枠側板部は、金属製の固定板とともに見込み面部を挟持して、固定具により固定されているので、見込み面部が固定板に補強される。このため、戸体から伝達される外力による見込み面部の変形を抑制することが可能である。 In this type of fixture, the hinge that rotatably attaches the door body has a frame side panel that is fixed to the projecting surface of the vertical frame. The projecting surface is sandwiched between the metal fixing plate and the fixing device, and the projecting surface is reinforced by the fixing plate. This makes it possible to prevent deformation of the projecting surface due to external forces transmitted from the door body.
また、戸体から伝達される外力は、丁番を介して枠体に伝達される。このため、戸体の面内方向に作用するモーメントが生じると、回動軸と戸体側部材との係合部を中心として枠側板部に外力が作用する。このため、枠側板部とともに見込み面部を挟持している固定板を見込み面部に固定している固定具を、上下方向に間隔を空けて複数配置し、そのうちの１つの位置を回動軸の先端と同じ高さ、または回動軸の先端よりも高い位置に配置することにより、戸体の面内方向に作用するモーメントに対しても見込み面部の変形を抑制することが可能となる。このため、戸体から丁番を介して伝達される外力が作用しても縦枠が変形しにくい建具を提供することが可能となる。 In addition, external forces transmitted from the door body are transmitted to the frame body via the hinge. Therefore, when a moment acting in the in-plane direction of the door body is generated, the external force acts on the frame side plate portion, centered on the engagement point between the pivot shaft and the door body side member. For this reason, by arranging multiple fasteners at intervals in the vertical direction to secure the fixing plate that clamps the projection surface portion together with the frame side plate portion to the projection surface portion, and by positioning one of them at the same height as the tip of the pivot shaft or higher than the tip of the pivot shaft, it is possible to suppress deformation of the projection surface portion even when a moment acting in the in-plane direction of the door body is applied. This makes it possible to provide a fitting whose vertical frame is less likely to deform even when an external force is transmitted from the door body via the hinge.
かかる建具であって、前記固定板の室内側の縁は、前記枠側板部の室内側の縁よりも室内側に位置することを特徴とする。 Such fittings are characterized in that the interior edge of the fixing plate is located closer to the interior than the interior edge of the frame side panel portion.
このような建具によれば、固定板の室内側の縁は、取り付けられた丁番の枠側板部における室内側の縁よりも室内側に位置されるので、戸体に外力が作用して、枠側板部の室内側が見込み面部を固定板側に押圧するように作用したとしても、見込み面部が押し込まれるような変形が固定板により規制される。このため、より変形しにくい縦枠を備えた建具を提供することが可能となる。 With this type of fitting, the interior-facing edge of the fixed plate is positioned further inside the room than the interior-facing edge of the frame side panel of the attached hinge. Therefore, even if an external force acts on the door body and the interior side of the frame side panel acts to press the projecting surface toward the fixed plate, the fixed plate will prevent the projecting surface from being pushed in. This makes it possible to provide fittings with vertical frames that are less likely to deform.
かかる建具であって、前記複数の固定具のうちの少なくとも１つの前記固定具の位置は、前記軸部の下端よりも低いことを特徴とする。 Such fittings are characterized in that the position of at least one of the multiple fasteners is lower than the lower end of the shaft.
このような建具によれば、固定板を見込み面部に固定する複数の固定具のうちの少なくとも１つの固定具の位置は、軸部の下端よりも低いので、丁番の枠側板部が固定される固定板は、上下に広く間隔を空けた２つの固定具により固定されることになる。このため、固定板及び枠側板部の面内方向における回転がより抑制されるので、戸体から伝達される外力による見込み面部の変形をより抑制することが可能である。 With this type of fitting, at least one of the multiple fasteners that secure the fixing plate to the recessed surface is positioned lower than the bottom end of the shaft, meaning that the fixing plate to which the hinge's frame side plate is fixed is secured by two fasteners that are widely spaced apart above and below. This further reduces in-plane rotation of the fixing plate and frame side plate, making it possible to further reduce deformation of the recessed surface due to external forces transmitted from the door body.
