Description

本発明は、ドア装置の防水構造に関するものである。 The present invention relates to a waterproof structure for a door device.

気密性が要求されるドア装置では、ドア枠に四周状の溝部を形成すると共に、当該四周状の溝部には、四周状の水密部材を装着してなり、開口部閉鎖時には、扉体の室内側の四周の周縁の角部が水密部材を押圧することで、気密性を確保している（図１５参照）。図１６に示すように、水密部材３´は、溝部に装着される基部４´と、中空状の膨出部５´と、を備えている。 In a door device that requires airtightness, a quadrilateral groove is formed in the door frame, and a quadrilateral watertight member is attached to the quadrilateral groove, and when the opening is closed, the door body chamber is formed. Airtightness is ensured by the corners of the inner four peripheral edges pressing the watertight member (see FIG. 15). As shown in FIG. 16, the watertight member 3 ′ includes a base portion 4 ′ attached to the groove portion and a hollow bulging portion 5 ′.

しかしながら、扉体によって閉鎖された建物開口部に水圧が作用した場合、この水圧でドア枠に取り付けられた水密部材３´が変形するが、中空状の膨出部５´の中空部が完全に潰れるものではないため水密状態が不安定であり、扉体の室内側面部２１´と水密部材３´の接触部に隙間が生じ、密閉状態を保持できなくなって、建物内部へ浸水が発生するおそれがある。 However, when water pressure acts on the building opening closed by the door body, the watertight member 3 ′ attached to the door frame is deformed by this water pressure, but the hollow portion of the hollow bulging portion 5 ′ is completely Since it is not crushed, the watertight state is unstable, and there is a possibility that a gap is formed in the contact portion between the indoor side surface portion 21 ′ of the door body and the watertight member 3 ′, so that the sealed state cannot be maintained, resulting in inundation inside the building. There is.

特許文献１に示すように、四周状の水密部材を二重に形成することも考えられるが、扉体及びドア枠の構造が複雑になり、コストの上昇を招くことになってしまう。
特開２０１４−１０９１６９ As shown in Patent Document 1, it is conceivable to form a double-circular watertight member doubly, but the structure of the door body and the door frame becomes complicated, leading to an increase in cost.

四周状の溝部（Ｇ１〜Ｇ４）は、全体として見た時に、室外側から見た正面視四周状で室内外方向に延びる外側辺（室外側水平面１０２の室内側部位１０２０、室外側見込面１１２の室内側部位１１２０、室外側見込面１２２の室内側部位１２２０、室外側傾斜面１３２の室内側部位１３２０）と、四周状の外側辺の内側に位置し、室外側から見た正面視四周状で室内外方向に延びる内側辺（室内側水平面１０３の室外側部位１０３０、室内側見込面１１３の室外側部位１１３０、室内側見込面１２３の室外側部位１２３０、室内側水平面１３３の室外側部位１３３０）と、外側辺と内側辺の室内側端部を接続する底辺（底面１０４、底面１１４、底面１２４、底面１３４）と、から形成されており、外側辺と内側辺と底辺とから断面視凹状の溝部となっている。そして、四周状の水密部材（３Ａ〜３Ｅ）は、基部４を外側辺と内側辺との間に押し入れることで、フィン４１が外側辺及び内側辺の内面に接触した状態で溝部（Ｇ１〜Ｇ４）に装着され、膨出部５は、溝部（Ｇ１〜Ｇ４）の外側（室外側）に位置しており、膨出部５に形成されたフィン５２は、溝部（Ｇ１〜Ｇ４）の外側（室外側）に位置して、外側辺（室外側水平面１０２、室外側見込面１１２、室外側見込面１２２、室外側傾斜面１３２）に接触ないし近接している。 The four-circular groove portions (G1 to G4), when viewed as a whole, have an outer side (an indoor side portion 1020 of the outdoor horizontal surface 102, an outdoor-side expected surface 112) that extends in the indoor-outward direction when viewed from the outdoor side. Indoor side part 1120, indoor side part 1220 of outdoor side expected surface 122, indoor side part 1320 of outdoor side inclined surface 132, and inside of the four-sided outer side, as viewed from the outdoor side, in a four-sided view in front view The inner side extending in the indoor / outdoor direction (the outdoor side portion 1030 of the indoor side horizontal surface 103, the outdoor side portion 1130 of the indoor side expected surface 113, the outdoor side portion 1230 of the indoor side expected surface 123, and the outdoor side portion 1330 of the indoor side horizontal surface 133) ) And bottom sides (bottom surface 104, bottom surface 114, bottom surface 124, bottom surface 134) that connect the indoor side end portions of the outer side and the inner side, and are concave in cross section from the outer side, the inner side, and the bottom side. And it has a groove. And a quadrilateral watertight member (3A-3E) is a groove part (G1-G1) in the state which the fin 41 contacted the inner surface of the outer side and the inner side by pushing the base part 4 between an outer side and an inner side. G4) is mounted, the bulging portion 5 is positioned outside (outside the outside of the groove) (G1 to G4), and the fin 52 formed on the bulging portion 5 is outside the groove (G1 to G4). It is located on the (outside of the room) and is in contact with or close to the outer side (outdoor side horizontal surface 102, outdoor side expected surface 112, outdoor side expected surface 122, outdoor side inclined surface 132).

図３、図４、図６に示すように、扉体２の通常の閉鎖姿勢時には、扉体２の室内側面部２１の四周縁が、四周状の水密部材３の膨出部５に軽く接触した状態であり、台座６と膨出部５の壁部５０の内面は離間している。図６を参照して詳細に説明すると、扉体２の室内側面部２１の戸先側部位が、水密部材３の膨出部５の壁部５０の正面部分５００に軽く接触しており、膨出部５が僅かに潰れて変形している。図示の態様では、第１側面部分５０１は、室内側見込面１１３の室外側部位１１３０に対して離間しており、第２側面部分５０２は、室外側見込面１１２に対して離間しており、フィン５２は、その先端が室外側見込面１１２に軽く接触している。 As shown in FIGS. 3, 4, and 6, when the door body 2 is normally closed, the four peripheral edges of the indoor side surface portion 21 of the door body 2 lightly contact the bulging portion 5 of the four-round watertight member 3. In this state, the pedestal 6 and the inner surface of the wall portion 50 of the bulging portion 5 are separated from each other. More specifically with reference to FIG. 6, the door side portion of the indoor side surface portion 21 of the door body 2 is in light contact with the front portion 500 of the wall portion 50 of the bulging portion 5 of the watertight member 3. The protruding portion 5 is slightly crushed and deformed. In the illustrated embodiment, the first side surface portion 501 is separated from the outdoor side portion 1130 of the indoor side expected surface 113, the second side surface portion 502 is separated from the outdoor side expected surface 112, The tips of the fins 52 are in light contact with the outdoor-side expected surface 112.

通常の閉鎖姿勢にある扉体２に室外側から室内側に水圧が作用すると、扉体２は、２重丁番２７によって、図３、図４の閉鎖姿勢からさらに室内側に押し付けられるように移動して、図１０〜図１２の姿勢となる。図１１に示すように、扉体２の戸先側と戸尻側がほぼ同じように室内側に押し込まれている。水位の高さに応じて水圧は扉体２の下方部位に作用するので、図１０に示すように、扉体２の下方部位が上方部位に比べて室内側に押し込まれている。 When water pressure acts on the door body 2 in the normal closed posture from the outdoor side to the indoor side, the door body 2 is further pressed against the indoor side from the closed posture of FIGS. It moves to the posture shown in FIGS. As shown in FIG. 11, the door end side and the door bottom side of the door body 2 are pushed into the indoor side in substantially the same manner. Since the water pressure acts on the lower part of the door body 2 according to the height of the water level, as shown in FIG. 10, the lower part of the door body 2 is pushed into the indoor side compared to the upper part.

閉鎖姿勢にある扉体２の室外側面部２０に水圧が作用すると、扉体２の室内側面部２１の四周の周縁及び扉体２の室内側の角部が、四周状の水密部材の膨出部５に当接して、当該膨出部５を室内側へ押圧する。膨出部５は、台座６に接近する方向に潰れるように変形して、壁部５０の内面が中実の台座６に当接する。中実の台座６は、変形した膨出部５を介して室内側へ押されるが、基部４及び台座６は溝部Ｇ１〜Ｇ４の底面１０４〜１３４に向かって幾分圧縮されたとしても、台座６の突出姿勢は維持される（図１０〜図１２参照）。したがって、中実の台座６が突っ張った状態で、変形した膨出部５の壁部５０（正面部分５００）の内面を支持し、このように内側から支持された壁部５０（正面部分５００）の外面に扉体２の室内側面部２１及び室内側の角部が密着状に当接する。 When water pressure acts on the outdoor side surface portion 20 of the door body 2 in the closed posture, the peripheral edge of the indoor side surface portion 21 of the door body 2 and the corner portion on the indoor side of the door body 2 bulge out of the quadrilateral watertight member. It abuts on the part 5 and presses the bulging part 5 to the indoor side. The bulging portion 5 is deformed so as to be crushed in a direction approaching the pedestal 6, and the inner surface of the wall portion 50 comes into contact with the solid pedestal 6. The solid pedestal 6 is pushed indoors through the deformed bulging portion 5, but the base 4 and the pedestal 6 are not compressed even if they are somewhat compressed toward the bottom surfaces 104 to 134 of the grooves G1 to G4. 6 is maintained (see FIGS. 10 to 12). Therefore, in the state where the solid pedestal 6 is stretched, the inner surface of the wall portion 50 (front portion 500) of the deformed bulging portion 5 is supported, and thus the wall portion 50 (front portion 500) supported from the inside. The indoor side surface portion 21 and the indoor corner portion of the door body 2 are in close contact with the outer surface of the door body 2.

図１２を参照しつつ、より具体的に説明する。なお、以下に述べる扉体２の戸先側部位における水密構造についての記載は、扉体２の戸尻側部位、下側部位、上側部位の水密構造に援用することができる。扉体２の室外側面部２０に水圧が作用して、扉体２の室内側面部２１及び室内側の角部（室内側面部２１と戸先側面部２３との角部）が水密部材の膨出部５を室内側へ押し込んだ時に、潰れるように変形した膨出部５の壁部５０の正面部分５００の内面が台座６の正面部分６０に当接するが、この時、壁部５０の正面部分５００は室外側に向かう突出姿勢の台座６の正面部分６０によって裏当てされており、正面部分５００は、内面に台座６の正面部分６０が当接し、外面に扉体２の室内側面部２１及び室内側の角部が密着した状態で、扉体２と台座６との間に挟持される。 This will be described more specifically with reference to FIG. In addition, the description about the watertight structure in the door tip side part of the door body 2 described below can be applied to the watertight structure of the door bottom side part, the lower part, and the upper part of the door body 2. Water pressure acts on the outdoor side surface portion 20 of the door body 2, and the indoor side surface portion 21 and the indoor side corner portion (the corner portion between the indoor side surface portion 21 and the door end side surface portion 23) of the door body 2 are expanded by the watertight member. When the protruding portion 5 is pushed into the room, the inner surface of the front portion 500 of the wall portion 50 of the bulging portion 5 deformed so as to be crushed comes into contact with the front portion 60 of the base 6. The portion 500 is backed by the front portion 60 of the pedestal 6 that protrudes toward the outdoor side, and the front portion 500 abuts the front portion 60 of the pedestal 6 on the inner surface, and the indoor side surface portion 21 of the door body 2 on the outer surface. And it is clamped between the door body 2 and the base 6 in the state which the corner | angular part of the room inner side contact | adhered.

扉体２の室外側面部２０に水圧が作用した場合であっても、中実の台座６の突出姿勢は維持される。図６と図１２を対比すると明らかなように、扉体２の室内側面部２０に水圧が作用することで、膨出部５が押しつぶされ、台座６及び基部４が溝部Ｇ２の底面１１４に向かって幾分圧縮されるが、台座６は室外側に向かう突出姿勢が維持されている。台座６は圧縮されて短縮され得るが、台座６の正面部分６０は、溝部Ｇ２の開口（室内側見込面１１３の室外側端部１１３１を通る垂直面によって規定される）よりも、室外側に位置している。したがって、水圧によって台座６及び基部４が底面１１４側に押し込まれ、台座６及び基部４が圧縮された場合であっても、常時、突出姿勢を維持した台座６が膨出部５の正面部分５００の内面に突っ張った状態で当接しているので、扉体２の室内側面部２１と膨出部５の正面部分５００の密着状態が良好に維持される。扉体２の室内側面部２１に押圧されて膨出部５が潰れて台座６に当接した状態では、膨出部５の外面と室内側面部２１との間に隙間が生じるような膨出部５の変形が規制されている。 Even when water pressure acts on the outdoor side surface portion 20 of the door body 2, the protruding posture of the solid base 6 is maintained. As apparent from the comparison between FIG. 6 and FIG. 12, when the water pressure acts on the indoor side surface portion 20 of the door body 2, the bulging portion 5 is crushed, and the base 6 and the base portion 4 face the bottom surface 114 of the groove portion G2. However, the pedestal 6 is maintained in a protruding posture toward the outdoor side. The pedestal 6 can be compressed and shortened, but the front portion 60 of the pedestal 6 is located more on the outdoor side than the opening of the groove G2 (defined by the vertical surface passing through the outdoor side end 1131 of the indoor side expected surface 113). positioned. Therefore, even if the pedestal 6 and the base 4 are pushed toward the bottom surface 114 side by water pressure and the pedestal 6 and the base 4 are compressed, the pedestal 6 that always maintains the protruding posture is the front portion 500 of the bulging portion 5. Therefore, the close contact state between the indoor side surface portion 21 of the door body 2 and the front portion 500 of the bulging portion 5 is maintained satisfactorily. In a state where the bulging portion 5 is crushed and pressed against the pedestal 6 by being pressed by the indoor side surface portion 21 of the door body 2, the bulging may cause a gap between the outer surface of the bulging portion 5 and the indoor side surface portion 21. The deformation of the part 5 is restricted.

水圧の作用によって膨出部５が容易に潰れることで、扉体２の室内側面部２１及び室内側の角部（室内側面部２１と戸先側面部２３との角部）と、潰れて変形した膨出部５と、がより強固に密着して、扉体２とドア枠１との隙間を水密に閉塞する。さらに、図１２に示すように、フィン５２のみならず、潰れるように変形した膨出部５の壁部５０の第２側面部分５０２が戸先側縦枠１１の外側見込面１１２に接触し、第１側面部分５０１が室内側見込面１１３の室外側端部１１３１の近傍に接触する。 As the bulging portion 5 is easily crushed by the action of water pressure, the indoor side surface portion 21 of the door body 2 and the corner portion on the indoor side (the corner portion of the indoor side surface portion 21 and the door side surface portion 23) are crushed and deformed. The bulging portion 5 is tightly adhered to tightly close the gap between the door body 2 and the door frame 1. Furthermore, as shown in FIG. 12, not only the fin 52 but also the second side surface portion 502 of the wall portion 50 of the bulging portion 5 deformed so as to be crushed contacts the outer expected surface 112 of the door-end side vertical frame 11, The first side surface portion 501 contacts the vicinity of the outdoor side end portion 1131 of the indoor side expected surface 113.
