Description

本発明は、例えば、バン型トラックの箱形荷室における後端部の開口部、あるいは車庫や倉庫等の構造物の出入り口を開閉する跳ね上げ扉の開閉装置に関する。   The present invention relates to an opening / closing device for a flip-up door that opens and closes an opening at a rear end of a box-type cargo compartment of a van type truck or a doorway of a structure such as a garage or a warehouse.

例えば、バン型トラックの箱形荷室における後端部の開口部を開閉する跳ね上げ扉は、係る扉の上辺と荷室の開口部の上辺との間に連結したゴム製または合成樹脂製のヒンジを介して、荷室の屋根に対して回転可能に取り付けられている。しかし、上記ゴム製または合成樹脂製のヒンジは、跳ね上げ扉の開閉が頻繁に行われると、ゴムや樹脂部分に亀裂などの破損を生じ、荷室内に漏水するなど耐久性に劣ると共に、交換作業にも手間を要し、交換回数も多くなるなどのメンテナンス上の問題もあった。
前記耐久性やメンテナンス上の問題を解決するため、箱形荷室における後端の屋根部に設ける第１ヒンジ構成部と、跳ね上げ式となる後部扉の上端に設ける第２ヒンジ構成部とを、相対的に回動可能で且つ相互に入り組んだ複雑な断面形状を有するアルミニウム合金からなる一対の押出形材によって構成したトラックなどの車両荷室の後部扉の開閉装置が提案されている（例えば、特許文献１参照）。 For example, a flip-up door that opens and closes an opening at the rear end of a box-type cargo compartment of a van type truck is made of rubber or synthetic resin connected between the upper side of the door and the upper side of the opening of the cargo compartment. It is rotatably attached to the roof of the luggage compartment via a hinge. However, if the hinge door made of rubber or synthetic resin is frequently opened and closed, the rubber or resin part will be damaged such as cracks and leaked into the cargo compartment, resulting in poor durability and replacement. There were also problems in maintenance such as work that required labor and increased number of replacements.
In order to solve the problems in durability and maintenance, a first hinge component provided on the roof portion at the rear end in the box-shaped cargo compartment and a second hinge component provided on the upper end of the rear door that is a flip-up type are provided. An opening / closing device for a rear door of a vehicle luggage compartment such as a truck constituted by a pair of extruded profiles made of an aluminum alloy having a complex cross-sectional shape that is relatively rotatable and intertwined with each other has been proposed (for example, , See Patent Document 1).

しかし、前記後部扉の開閉装置では、荷室側と後部扉側の第１・第２ヒンジ構成部が何れも上記押出形材であり、且つ相互に入り組んだ複雑な断面形状を有するため、形状および寸法について高い公差レベルの押出成形精度を要し、且つ相対的に回転可能となるように嵌合するために高度な熟練が必要となる。また、前記一対の押出形材相互の軸受部分や、断面円弧形の凸形回転部分と係る回転部分を移動可能に受け入れる凹形ガイド部分とおいて、アルミニウム同士が直かに接触するので、頻繁な開閉に伴って摩耗を生じ、ガタ付き易くなる。更に、上記扉の開閉途中に摩擦音が生じると共に、上記扉を閉鎖および開放するたびにアルミニウム同士が面状に当たるため衝突音も発生する。しかも、後部扉側の第２ヒンジ構成部となる押出形材は、荷室の外側に開口する水平な面を有するため、係る開口部内に進入する雨水が排水されにくく、且つ上記水平な面上に付着した塵埃などを除去しにくい、という問題があった。   However, in the rear door opening and closing device, the first and second hinge constituent portions on the cargo compartment side and the rear door side are both the above extruded shape members and have a complicated cross-sectional shape interlaced with each other. In addition, a high tolerance level of extrusion accuracy is required for the dimensions, and a high degree of skill is required for fitting so as to be relatively rotatable. Further, since the aluminum is in direct contact with each other in the pair of extruded profiles and the concave guide portion that movably receives the rotating portion with the arcuate cross-section of the convex rotating portion, Wear occurs with the open / close operation, and becomes loose. Furthermore, a frictional sound is generated during the opening and closing of the door, and a collision sound is also generated because the aluminum strikes the surface each time the door is closed and opened. Moreover, since the extruded shape member that becomes the second hinge component on the rear door side has a horizontal surface that opens to the outside of the cargo compartment, rainwater entering the opening is difficult to be drained, and on the horizontal surface. There is a problem that it is difficult to remove dust and the like adhering to the surface.

特許第３２８６９１４号公報 （第１〜６頁、図１〜３）Japanese Patent No. 3286914 (pages 1-6, FIGS. 1-3)

本発明は、背景技術において説明した問題点を解決し、高い成形精度を要さず、且つ容易に組立でき、開閉に伴う摩耗やガタ付きや、開閉途中や閉鎖・開放時に摩擦音や衝突音が生じにくく、且つ雨水や塵埃が付着しにくくし得る跳ね上げ扉の開閉装置（開閉構造）を提供する、ことを課題とする。   The present invention solves the problems described in the background art, does not require high molding accuracy, can be easily assembled, wears and rattles associated with opening and closing, and generates friction and collision sounds during opening and closing, and during closing and opening. It is an object of the present invention to provide an open / close device (opening / closing structure) for a flip-up door that is unlikely to occur and that is difficult to attach rainwater and dust.

課題を解決するための手段および発明の効果Means for Solving the Problems and Effects of the Invention

本発明は、前記課題を解決するため、発明者らによる鋭意研究の結果得られたものであり、トラックの荷室や車庫などの開口部側の上枠と、跳ね上げ扉側の回動枠とをアルミニウム合金などの金属製形材とし、且つ係る一対の形材間に硬質樹脂の滑り材を常に挟んで開閉する、ことに着想して成されたものである。
即ち、本発明による跳ね上げ扉の開閉装置（請求項１）は、車両または構造物の内外を区画する垂直な開口部を開閉する跳ね上げ扉の開閉装置であって、前記開口部の上辺に固定される金属形材製の上枠と、上記跳ね上げ扉の上辺に固定される金属形材製の回動枠と、硬質樹脂からなり、上記上枠と回動枠との間に配設される滑り材と、を含み、上記上枠は、上記開口部の上辺に固定される水平な固定片と、係る固定片の一端側から垂下する縦片と、係る縦片の下方に連設し且つ内側に斜め上向きに開口する断面円弧形の軸受面を有する断面Ｊ字形状の軸受片と、を備え、上記回動枠は、上記跳ね上げ扉による開口部の閉鎖時において、前記扉の上辺部を挟む内外一対の取付片と、係る一対の取付片の上方に形成され且つ内側から外側に下がるように傾斜する勾配片と、係る勾配片の上端から上記上枠の固定片側に立ち上がり且つ断面が半円形状の回動片と、係る回動片の上端から上記上枠の縦片の内側面に沿って延びるストッパ片と、係るストッパ片の下端に位置し且つ上記上枠の軸受面の内側で回転自在となる断面円形状の軸部と、を備え、上記滑り材は、上記上枠の軸受面と回動枠の軸部との間に挟まれる円弧片と、該円弧片の一端から延び且つ上記上枠の軸受片の下側面と回動枠の回動片の外側面との間に沿って延び出た摺動片と、を備えている、ことを特徴とする。 In order to solve the above-mentioned problems, the present invention has been obtained as a result of intensive studies by the inventors, and includes an upper frame on the opening side of a truck luggage compartment, a garage, and the like, and a rotary frame on the flip-up door side. Are made of a metal shape material such as an aluminum alloy, and the hard resin sliding material is always sandwiched between the pair of shape materials to open and close.
That is, the door opening and closing device according to the present invention (Claim 1) is a door opening and closing device that opens and closes a vertical opening that partitions the inside or outside of a vehicle or a structure, and is provided on the upper side of the opening. A metal-shaped upper frame to be fixed, a metal-shaped rotating frame fixed to the upper side of the flip-up door, and a hard resin, disposed between the upper frame and the rotating frame. The upper frame includes a horizontal fixing piece fixed to the upper side of the opening, a vertical piece hanging from one end side of the fixing piece, and a lower part of the vertical piece. And a J-shaped bearing piece having an arc-shaped bearing surface that opens obliquely upward on the inside, and the rotating frame is configured to open the door when the opening is closed by the flip-up door. A pair of inner and outer mounting pieces sandwiching the upper side of the upper portion, and formed above the pair of mounting pieces, and downward from the inner side to the outer side. Inclined slope piece, a turning piece that rises from the upper end of the slope piece to the fixed piece side of the upper frame and has a semicircular cross section, and the inner side surface of the vertical piece of the upper frame from the upper end of the turning piece And a shaft portion having a circular cross section that is positioned at the lower end of the stopper piece and is rotatable inside the bearing surface of the upper frame. An arc piece sandwiched between the bearing surface and the shaft portion of the rotating frame, and extending between one end of the arc piece and between the lower surface of the bearing piece of the upper frame and the outer surface of the rotating piece of the rotating frame And a sliding piece extending along the line.

これによれば、車両などの開口部に固定される金属形材製の上枠と、跳ね上げ扉の上辺に固定され且つ上枠の軸受面に挿入される軸部を中心に回転可能となる金属形材製の回動枠との間に、硬質樹脂からなる比較的長尺の滑り材が配設されるため、上記扉の開閉時においてメタルタッチ（金属同士の接触）がなくなる。その結果、上記扉の開閉時に生じる摩擦、摩耗、およびガタ付きが低減されるので、係る開閉操作時に要する労力を低減でき、且つ摩擦に伴う音も生じにくくなる。しかも、上枠と回動枠とを構成する押出形材などの金属形材の形状および寸法に関する成形精度が緩やかなレベルの公差で済むので、係る金属形材の製造や相互の組立（嵌合）も容易となる。
更に、上枠は、前記固定片のほか、全体の断面がほぼＪ字形を呈する縦片と軸受片とのみからなり、且つ係る軸受片の軸受面に回動枠の軸部が片持ち状に吊り下げられて前記扉が回転可能に支持される。その結果、上枠と回動枠との断面形状が、前記特許文献１の第１・第２ヒンジ構成部のように、互いに入り組んだ複雑な断面形状とならず、比較的シンプルな断面形状となるので、軽量化も図れる。
加えて、回動枠は、内外一対の取付片と回動片との間に外側に下がるように傾斜した勾配片を有するか、あるいは該回動枠に取り付ける別体の水切り材に設けた凹溝が雨樋の働きを成すので、雨水が溜まることなく、速やかに外部へ排水できると共に、塵埃などの付着を抑制でき且つその除去も容易となる。
従って、高い成形精度を要さず、且つ容易に組立ができ、開閉に伴う摩耗やガタ付きや、開閉途中に摩擦音や衝突音が生じにくい共に、メンテナンスも容易な跳ね上げ扉を提供することが可能となる。 According to this, it becomes possible to rotate around an upper frame made of a metal shape member fixed to an opening of a vehicle or the like and a shaft portion fixed to the upper side of the flip-up door and inserted into the bearing surface of the upper frame. Since a relatively long sliding material made of a hard resin is disposed between the metal-shaped rotating frame, metal touch (contact between metals) is eliminated when the door is opened and closed. As a result, the friction, wear, and rattling that occur when the door is opened and closed are reduced, so that the labor required for the opening and closing operation can be reduced, and noise associated with friction is less likely to occur. In addition, since the forming accuracy with respect to the shape and dimensions of metal shapes such as extruded shapes that make up the upper frame and the rotating frame can be handled with a moderate level of tolerance, the manufacture of such metal shapes and their mutual assembly (fitting) ) Is also easier.
In addition to the fixed piece, the upper frame is composed of only a vertical piece and a bearing piece whose overall cross section is substantially J-shaped, and the shaft portion of the rotating frame is cantilevered on the bearing surface of the bearing piece. It is suspended and the door is rotatably supported. As a result, the cross-sectional shape of the upper frame and the rotating frame is not a complicated cross-sectional shape complicated with each other as in the first and second hinge constituent parts of Patent Document 1, but a relatively simple cross-sectional shape. Therefore, the weight can be reduced.
In addition, the rotating frame has a sloped piece inclined so as to fall outward between the pair of inner and outer mounting pieces and the rotating piece, or a recess provided in a separate draining material attached to the rotating frame. Since the groove functions as a rain gutter, rainwater does not accumulate and can be quickly drained to the outside, and adhesion of dust and the like can be suppressed and its removal can be facilitated.
Accordingly, it is possible to provide a flip-up door which does not require high molding accuracy and can be easily assembled, is not easily worn or rattled by opening and closing, is less likely to generate friction noise and collision noise during opening and closing, and is easy to maintain. It becomes possible.

The structure includes a large structure such as a hangar as well as a garage or a warehouse.
Furthermore, in addition to the extruded shape of aluminum alloy, the metal profile includes, for example, mold steel and a metal assembly material in which a plurality of mold steels are joined by welding or the like.
The hard resin constituting the sliding material includes polyethylene (PE), polypropylene (PP), polymethylpentene (PMP), and the like.
Further, the sliding material is obtained by injection molding or extrusion molding of PE or the like, and since each portion is thin as will be described later, the sliding material has high elasticity that easily changes its shape.
Further, the door body of the flip-up door has a form in which a single metal plate is molded, a form in which a plywood or the like is attached to the inner side surface of the metal thin plate, and a heat insulating material or a heat insulating material between a pair of inner and outer metal thin plates. Includes the form of filled sandwich panels.
In addition to the form that opens and closes the entire surface of one opening, the flip-up door opens and closes only the upper door in the folding door type in which a pair of upper and lower doors are connected by a hinge and the upper half of the opening. And the form used together with the lower door which opens and closes a lower half part is also included.

また、本発明には、前記上枠は、係る上枠の縦片の内側面で且つ該上枠の軸受面の上方に、断面三角形状の凸部を有し、前記滑り材は、該滑り材の円弧片の他端に、上記凸部に沿って上向きに延びた第１緩衝片を連設していると共に、上記滑り材の第１緩衝片は、前記跳ね上げ扉による開口部の閉鎖時において、上記凸部と前記回動枠のストッパ片との間に挟持されると共に、上記滑り材の円弧片と摺動片との間に位置する第２緩衝片は、上記跳ね上げ扉による開口部の開放時において、上枠の軸受片の先端面と回動枠のストッパ片との間に挟持される、跳ね上げ扉の開閉装置（請求項２）も含まれる。
これによれば、跳ね上げ扉の閉鎖時と開放時との双方において、滑り材の第１緩衝片および第２緩衝片の何れか一方が、常に、上枠の凸部と回動枠のストッパ片との間、あるいは上枠の軸受片の先端面と回動枠のストッパ片との間に挟持される。その結果、前記扉の閉鎖時および開放時の何れにおいても、上枠と回動枠とのメタルタッチを確実に防げるので、摩擦および摩耗を低減でき、且つ衝突音を抑制ないし皆無にすることも可能となる。 Further, according to the present invention, the upper frame has a convex portion having a triangular cross section on the inner side surface of the vertical piece of the upper frame and above the bearing surface of the upper frame, and the sliding member includes the sliding member. A first buffer piece extending upward along the convex portion is connected to the other end of the arc piece of the material, and the first buffer piece of the sliding material is closed by the flip-up door. At this time, the second buffer piece that is sandwiched between the convex portion and the stopper piece of the rotating frame and located between the arc piece and the sliding piece of the sliding member is formed by the flip-up door. Also included is a flip-up door opening and closing device that is sandwiched between the tip surface of the bearing piece of the upper frame and the stopper piece of the rotating frame when the opening is opened.
According to this, in both the closing and opening of the flip-up door, one of the first buffer piece and the second buffer piece of the sliding member is always the convex part of the upper frame and the stopper of the rotating frame. It is clamped between the pieces or between the tip end surface of the bearing piece of the upper frame and the stopper piece of the rotating frame. As a result, the metal touch between the upper frame and the rotating frame can be reliably prevented both when the door is closed and opened, so that friction and wear can be reduced, and the collision noise can be suppressed or eliminated. It becomes possible.

更に、本発明には、前記回動枠における回動片の下端と勾配片の上端とは、互いに離間しているか、あるいは、段部を介して離間している、跳ね上げ扉の開閉装置（請求項３）も含まれる。
これによれば、回動枠の勾配片に降った雨水や付着した塵埃などを、当該回動枠の回動片と滑り材の摺動片との隙間に巻き込んだり、上記雨水などが回動片側進入する事態を抑制することができる。更に、互いに段部を介して離間している形態では、上記雨水や塵埃の回動片側への巻き込みや進入を、一層確実に防止することが可能となる。 Further, according to the present invention, the lower end of the rotating piece and the upper end of the gradient piece in the rotating frame are separated from each other or separated through a step portion (opening / closing door opening / closing device ( Claim 3) is also included.
According to this, rain water or dust adhering to the gradient piece of the rotating frame is caught in the gap between the rotating piece of the rotating frame and the sliding piece of the sliding material, or the rain water or the like rotates. The situation of entering one side can be suppressed. Furthermore, in the form of being separated from each other via the stepped portion, it becomes possible to more reliably prevent the rainwater and dust from being caught and entered into the rotating piece side.

また、本発明には、前記上枠の軸受片は、断面円弧形の下側面に凹部を有し、該凹部は、前記滑り材の摺動片の先端部を係止する内側段部と、下向きの外側段部と、を有しているか、あるいは上記軸受片の下側面と外側面との間に上記滑り材の摺動片の先端部を係止する外向き段部を有している、跳ね上げ扉の開閉装置（請求項４）も含まれる。
これによれば、上記軸受片に設ける凹部の内側段部あるいは外向き段部に滑り材の摺動片の先端部を係止できるので、係る滑り材の上枠への強固な装着が可能となる。一方、上記凹部による場合、該凹部の外側段部により、上枠の縦片や軸受片の外側面に降って流下する雨水を水切りして、滑り材側への進入を防ぎ、且つ係る雨水を回動枠の勾配片の上に確実に流下できる。 Further, according to the present invention, the bearing piece of the upper frame has a concave portion on the lower side surface of the arcuate cross section, and the concave portion has an inner step portion for locking the tip end portion of the sliding piece of the sliding material. A downward outer step, or an outer step for locking the tip of the sliding piece of the sliding material between the lower surface and the outer surface of the bearing piece. Further, a flip-up door opening and closing device (claim 4) is also included.
According to this, since the tip of the sliding piece of the sliding material can be locked to the inner stepped portion or the outward stepped portion of the concave portion provided in the bearing piece, it is possible to firmly attach the sliding material to the upper frame. Become. On the other hand, in the case of the recess, the outer stepped portion of the recess drains rainwater that falls down and flows down to the outer surface of the vertical piece of the upper frame and the bearing piece to prevent entry to the sliding material side, and to remove the rainwater. It can surely flow down on the sloped piece of the rotating frame.

更に、本発明には、前記回動枠における勾配片の外側には、係る勾配片から外側に延びた斜め部と、係る斜め部の先端から垂下する水切部とからなる水切片が連設されている、跳ね上げ扉の開閉装置（請求項５）も含まれる。
これによれば、回動枠の勾配片上に降った雨水や、上枠の外側面を伝って当該勾配片上に流下した雨水を、跳ね上げ扉の外側面から更に外側の車外または屋外へ確実に排水できる。その結果、上記扉の汚れや腐食などの劣化を抑制でき、メンテナンスを低減することも可能となる。
加えて、本発明には、前記回動枠における勾配片の上方と外側の取付片の外方とには、係る勾配片の上方に位置し且つ前記滑り材の摺動片に接近する湾曲面を有する湾曲片と、上記外側の取付片の外側面に隣接する縦片と、係る縦片と上記湾曲片との間に位置し、且つ斜め外上向きに開口する凹溝とを備えた水切り材が取り付けられている、跳ね上げ扉の開閉装置（請求項６）も含まれる。
これによれば、跳ね上げ扉の閉鎖時において、上枠の軸受片に巻き付けた滑り材の摺動片と、水切り材の湾曲片との隙間を内外方向に沿って細長く且つ小さくすることで、雨水や塵埃の浸入を一層抑制することができる。しかも、水切り材の凹溝に入った雨水は、両端の開口部から外部に排水され、該雨水が上記扉の外側面を流下しなくなるので、該扉の外側面に雨水によるシミが生じにくくなる。 Further, in the present invention, outside the slope piece in the rotating frame, a water section composed of an oblique portion extending outward from the slope piece and a draining portion hanging from the tip of the oblique portion is continuously provided. The flip-up door opening and closing device (Claim 5) is also included.
According to this, rainwater that has fallen on the gradient piece of the rotating frame and rainwater that has flowed down on the gradient piece along the outer surface of the upper frame can be reliably transferred from the outer surface of the flip-up door to the outside of the vehicle or outside. Can drain. As a result, deterioration of the door such as dirt and corrosion can be suppressed, and maintenance can be reduced.
In addition, according to the present invention, a curved surface that is located above the gradient piece and is close to the sliding piece of the sliding member is provided above the gradient piece and outside the outer attachment piece in the rotation frame. A draining material provided with a curved piece having a vertical piece adjacent to the outer surface of the outer mounting piece, and a concave groove located between the vertical piece and the curved piece and opened obliquely outward and upward. The door opening / closing device (Claim 6) is also included.
According to this, by closing the gap between the sliding piece of the sliding material wound around the bearing piece of the upper frame and the curved piece of the draining material at the time of closing the flip-up door, it is elongated and small along the inner and outer directions, Infiltration of rainwater and dust can be further suppressed. In addition, the rainwater that has entered the groove of the draining material is drained to the outside through the openings at both ends, and the rainwater does not flow down the outer surface of the door, so that it is difficult for stains due to rainwater to occur on the outer surface of the door. .

前記滑り材４０は、前記硬質樹脂製からなる比較的長尺な枠材であり、図３の上方に示すように、前記上枠２の軸受面７と回動枠２０の軸部３３との間に挟まれる断面が半円形状の円弧片４２と、該円弧片４２の他端（外端）から前記上枠２の凸部９の内側面に沿って上向きに延びた第１緩衝片４４と、上記円弧片４２の一端（内端）から延びた水平な第２緩衝片４５と、係る第２緩衝片４５の一端（内端）から延び且つ上枠２の軸受片６の下側面と回動枠２０の回動片３０の外側面３１との間に沿って湾曲して延び出た摺動片４６と、を図示の奥行き方向に沿った全長に備えている。
上記摺動片４６の外端には、上枠２の凹部８の内側段部８ａに係止される先端部４７が斜め上向きに突設され、係る先端部４７を含む当該摺動片４６と、第２緩衝片４５と、上記円弧片４２との間には、上枠２の軸受片６の先端面６ａ側が挿入されるカーブ溝４８が位置している。尚、上記滑り材４０は、各部分の厚さが約０．５ｍｍと薄肉であるため、容易に弾性変形し得る。 The sliding member 40 is a relatively long frame member made of the hard resin. As shown in the upper part of FIG. 3, the sliding member 40 includes a bearing surface 7 of the upper frame 2 and a shaft portion 33 of the rotating frame 20. An arc piece 42 having a semicircular cross section sandwiched therebetween, and a first buffer piece 44 extending upward from the other end (outer end) of the arc piece 42 along the inner surface of the convex portion 9 of the upper frame 2. A horizontal second buffer piece 45 extending from one end (inner end) of the arc piece 42, and a lower surface of the bearing piece 6 of the upper frame 2 extending from one end (inner end) of the second buffer piece 45 The sliding piece 46 which curvedly extended along the outer surface 31 of the rotation piece 30 of the rotation frame 20 is provided in the full length along the depth direction of illustration.
At the outer end of the sliding piece 46, a tip end portion 47 that is locked to the inner step portion 8a of the concave portion 8 of the upper frame 2 protrudes obliquely upward, and the sliding piece 46 including the tip end portion 47 and Between the second buffer piece 45 and the arc piece 42, a curved groove 48 into which the front end face 6a side of the bearing piece 6 of the upper frame 2 is inserted is located. In addition, since the thickness of each part is as thin as about 0.5 mm, the sliding material 40 can be easily elastically deformed.

本発明の開閉装置１を構成するには、図３中の白抜き矢印で示すように、滑り材４０を弾性変形させて、前記カーブ溝４８の入口を大きく開いた状態で、係る滑り材４０を、その断面方向に沿って、カーブ溝４８内に前記上枠２の軸受片６の先端面６ａ側を挿入すると共に、当該滑り材４０の円弧片４２を上枠２の軸受面７内に押し込む操作を行う。
その結果、図４に示すように、上枠２の軸受面７内に滑り材４０の円弧片４２が隙間なく嵌め込まれ、且つ滑り材４０のカーブ溝４８内に上枠２の軸受片６の先端面６ａ側が挿入される。同時に、滑り材４０の第１緩衝片４４は、上枠２の凸部９の内側面に面接触し、滑り材４０の第２緩衝片４５は、上枠２の軸受片６の先端面６ａに面接触すると共に、滑り材４０の摺動片４６の先端部４７は、上枠２の凹部８における内側段部８ａに係止される。 In order to configure the opening / closing device 1 of the present invention, as shown by the white arrow in FIG. 3, the sliding material 40 is elastically deformed so that the entrance of the curved groove 48 is widely opened. Along the cross-sectional direction, the tip end surface 6a side of the bearing piece 6 of the upper frame 2 is inserted into the curved groove 48, and the arc piece 42 of the sliding member 40 is inserted into the bearing surface 7 of the upper frame 2. Push in.
As a result, as shown in FIG. 4, the arc piece 42 of the sliding member 40 is fitted into the bearing surface 7 of the upper frame 2 without a gap, and the bearing piece 6 of the upper frame 2 is inserted into the curved groove 48 of the sliding member 40. The tip surface 6a side is inserted. At the same time, the first buffer piece 44 of the sliding material 40 is in surface contact with the inner surface of the convex portion 9 of the upper frame 2, and the second buffer piece 45 of the sliding material 40 is the tip surface 6 a of the bearing piece 6 of the upper frame 2. The tip 47 of the sliding piece 46 of the sliding member 40 is engaged with the inner step 8 a in the recess 8 of the upper frame 2.

次に、図４に示すように、滑り材４０が内側（ＩＮ）に装着された上枠２に対し、これらの長手（押出）方向に沿って、跳ね上げ扉Ｄの上辺に沿って固定された回動枠２０を、その軸部３３が滑り材４０の円弧片４２の内側に挿入され、ストッパ片３４の外側面３５が滑り材４０の第１緩衝片４４の内側面に面接触すると共に、回動枠２０のガイド溝２９内の入口側に、滑り材４０の円弧片４２の内側部分、第２緩衝片４５、およびこれに隣接する摺動片４６の基端側が挿入されるように、差し込む。
その結果、図４に示すように、回動枠２０の軸部３３は、上枠２の軸受片６の軸受面７および滑り材４０の円弧片４２の内側に同心円状にして挿入され、回動枠２０のストッパ片３４の外側面３５は、滑り材４０の第１緩衝片４４に面接触する。同時に、上枠２の軸受片６の先端面６ａ側および滑り材４０の第２緩衝片４５とこれに隣接する摺動片４６は、回動枠２０のガイド溝２９内の入口側に進入し、且つ上記摺動片４６と回動枠２０の回動枠３０の外側面３１とは、互いに接近し且つ平行な姿勢となる。しかも、回動枠２０を含む跳ね上げ扉Ｄは、滑り材４０を介して上枠２に垂直姿勢で支持されることによって、開口部Ｋを内側（ＩＮ）と外側（ＯＵＴ）とに遮蔽（区画）した閉鎖状態としている。 Next, as shown in FIG. 4, the sliding member 40 is fixed along the upper side of the flip-up door D along the longitudinal (extrusion) direction with respect to the upper frame 2 mounted on the inner side (IN). The shaft portion 33 of the rotating frame 20 is inserted inside the arc piece 42 of the sliding member 40, and the outer side surface 35 of the stopper piece 34 is in surface contact with the inner side surface of the first buffer piece 44 of the sliding member 40. The inner side portion of the arc piece 42 of the sliding member 40, the second buffer piece 45, and the proximal end side of the slide piece 46 adjacent thereto are inserted into the entrance side in the guide groove 29 of the rotating frame 20. Plug in.
As a result, as shown in FIG. 4, the shaft portion 33 of the rotating frame 20 is inserted concentrically inside the bearing surface 7 of the bearing piece 6 of the upper frame 2 and the arc piece 42 of the sliding material 40, and rotates. The outer surface 35 of the stopper piece 34 of the moving frame 20 is in surface contact with the first buffer piece 44 of the sliding material 40. At the same time, the end face 6 a side of the bearing piece 6 of the upper frame 2 and the second buffer piece 45 of the sliding member 40 and the sliding piece 46 adjacent thereto enter the inlet side in the guide groove 29 of the rotating frame 20. In addition, the sliding piece 46 and the outer surface 31 of the rotating frame 30 of the rotating frame 20 are close to each other and in a parallel posture. Moreover, the flip-up door D including the rotating frame 20 is supported by the upper frame 2 in a vertical posture via the sliding member 40, thereby shielding the opening K from the inside (IN) to the outside (OUT) ( It is in a closed state.

これによって、本発明による跳ね上げ扉Ｄの開閉装置１が組み立てられた。
尚、開閉装置１の上記扉Ｄによる閉鎖状態を保持するため、図示しない錠前などの金具が前記下部扉ｄと開口部Ｋの床面との間に配置されている。
図４に示すように、上記扉Ｄによって開口部Ｋが遮蔽された閉鎖状態では、上枠２の化粧片４、縦片５、および軸受片６の外側面に降って流下した雨水は、凹部８の外側段部８ｂによる水切り作用によって、回動枠２０の勾配片２６上に滴下ないし流下する。また、係る勾配片２６上に降る風を伴った雨水は、回動片３０との間に位置する段部２８によって、ガイド溝２９内への巻き込みを阻止され、上記勾配片２６に連続して傾斜する水切片３７の斜め部を３８上を流下し、更に水切部３８により前記扉Ｄの外側（ＯＵＴ）へ排水される。 Thereby, the opening / closing device 1 of the flip-up door D according to the present invention was assembled.
In order to maintain the closed state of the opening / closing device 1 by the door D, a metal fitting such as a lock (not shown) is disposed between the lower door d and the floor surface of the opening K.
As shown in FIG. 4, in the closed state in which the opening K is shielded by the door D, the rain water that has flowed down to the outer surface of the decorative piece 4, the vertical piece 5, and the bearing piece 6 of the upper frame 2 is recessed. By the draining action by the outer stepped portion 8b of the No. 8, it drops or flows down on the gradient piece 26 of the rotating frame 20. Further, the rain water accompanied by the wind falling on the gradient piece 26 is prevented from being caught in the guide groove 29 by the step portion 28 located between the rotation piece 30 and continuously to the gradient piece 26. The slanting portion of the inclined water section 37 flows down on the surface 38 and is further drained to the outside (OUT) of the door D by the draining portion 38.

次いで、前記開閉装置１において、跳ね上げ扉Ｄの下辺中央付近に設けた図示しない持ち手を掴んで、回動枠２０の軸部３３を回転中心として、図５中のカーブした矢印で示すように、上記扉Ｄを外側（ＯＵＴ）の斜め上方に持ち上げる。
その結果、図５に示すように、回動枠２０を含む跳ね上げ扉Ｄは、前記垂直姿勢から垂直方向に沿って斜め上方に約１２０°回転（跳ね上げ）した開放状態となる。これによって、開口部Ｋを介して内側（ＩＮ）と外側（ＯＵＴ）とが連通し、積荷の出し入れ作業や、自動車などの出庫または入庫が可能となる。
尚、上記開放状態を保つため、上記扉Ｄの縦辺と開口部Ｋの縦辺との間には、図示しない伸縮式のステーなどが張設される。
図５に示す開放状態にする際、回動枠２０は、そのストッパ片３４の内側面３６が、滑り材４０の第２緩衝片４５に面接触した位置で停止する。同時に、回動枠２０の回動片３０の外側面３１は、滑り材４０の摺動片４６にほぼ面接触すると共に、上枠２の凹部８の外側段部８ｂ付近の外側面にも、平行状にて接近する。 Next, in the opening / closing device 1, a handle (not shown) provided near the center of the lower side of the flip-up door D is grasped, and as indicated by a curved arrow in FIG. Then, the door D is lifted obliquely upward on the outside (OUT).
As a result, as shown in FIG. 5, the flip-up door D including the rotation frame 20 is in an open state that is rotated about 120 ° (bounce-up) obliquely upward along the vertical direction from the vertical posture. As a result, the inside (IN) and the outside (OUT) communicate with each other through the opening K, and loading / unloading work and loading / unloading of automobiles and the like are possible.
In order to maintain the open state, a telescopic stay (not shown) is stretched between the vertical side of the door D and the vertical side of the opening K.
In the open state shown in FIG. 5, the rotating frame 20 stops at a position where the inner side surface 36 of the stopper piece 34 is in surface contact with the second buffer piece 45 of the sliding member 40. At the same time, the outer surface 31 of the rotating piece 30 of the rotating frame 20 is substantially in surface contact with the sliding piece 46 of the sliding member 40 and also on the outer surface of the upper frame 2 in the vicinity of the outer step portion 8b of the concave portion 8. Approach in parallel.

以上のような跳ね上げ扉Ｄの開閉装置１によれば、押出形材製の上枠２と回動枠２０との間に、比較的長尺な硬質樹脂製の滑り材４０が配設されているので、上記扉Ｄの全ての開閉時においてメタルタッチがなくなる。その結果、上記扉Ｄの開閉時の摩擦や摩耗が低減され、摩耗やガタ付きが生じにくく、開閉操作に要する労力を低減できると共に、摩擦に伴う音を抑制でき、且つ開放終了時および閉鎖終了時の衝突音も防止することができる。
また、上枠２と回動枠２０とを構成する押出形材の形状や寸法に関する成形精度が緩やかな公差で済むので、係る押出形材の製造や相互の組立も容易となる。
更に、前記上枠２は、固定片３と、断面がほぼＪ字形を呈する縦片５および軸受片６とを必須とし、且つ軸受片６の軸受面７に回動枠２０の軸部３３を片持ち状に吊り下げて前記扉Ｄが回転可能に支持するため、上枠２の断面形状と回動枠２０の断面形状とが、互いに入り組んだ複雑な断面形状とならず、比較的シンプルな断面形状となるので、これらに用いる押出形材の軽量化も図り得る。
加えて、回動枠２０は、外側（ＯＵＴ）に下るように傾斜した勾配片２６および水切り片３７を有するので、雨水を速やかに外側（ＯＵＴ）へ排水でき、塵埃などの付着を抑制し、且つそれらの除去も容易となる。
従って、前記開閉装置１によれば、高い成形精度を要さず、且つ容易に組立でき、開閉に伴う摩耗およびガタ付きや、開閉途中および開閉終了時に摩擦音や衝突音が生じ難い共に、メンテナンスも容易な跳ね上げ扉Ｄを提供可能となる。 According to the opening / closing device 1 for the flip-up door D as described above, the relatively long hard resin sliding member 40 is disposed between the upper frame 2 made of the extruded shape member and the rotary frame 20. Therefore, there is no metal touch when all the doors D are opened and closed. As a result, friction and wear during opening and closing of the door D are reduced, wear and backlash are unlikely to occur, labor required for opening and closing operations can be reduced, noise caused by friction can be suppressed, and opening and closing ends The collision sound at the time can also be prevented.
In addition, since the forming accuracy with respect to the shape and dimensions of the extruded shapes constituting the upper frame 2 and the rotating frame 20 can be made with a moderate tolerance, manufacturing of the extruded shapes and mutual assembly are facilitated.
Further, the upper frame 2 requires a fixed piece 3, a vertical piece 5 and a bearing piece 6 having a substantially J-shaped cross section, and the shaft portion 33 of the rotating frame 20 is provided on the bearing surface 7 of the bearing piece 6. Since the door D is supported in a rotatable manner by being suspended in a cantilever shape, the cross-sectional shape of the upper frame 2 and the cross-sectional shape of the rotating frame 20 are not complicated complicated cross-sectional shapes, and are relatively simple. Since it becomes a cross-sectional shape, weight reduction of the extruded shape member used for these can also be achieved.
In addition, since the rotation frame 20 has the slope piece 26 and the draining piece 37 inclined so as to descend to the outside (OUT), rainwater can be quickly drained to the outside (OUT), and adhesion of dust and the like is suppressed. Moreover, they can be easily removed.
Therefore, the opening / closing device 1 does not require high molding accuracy and can be easily assembled, wear and backlash associated with opening / closing, friction noise and collision noise during opening / closing and at the end of opening / closing are not easily generated, and maintenance is also performed. An easy flip-up door D can be provided.

図６は、異なる形態の跳ね上げ扉Ｄの開閉装置１ａの閉鎖状態を示す部分垂直断面である。上記扉Ｄの開閉装置１ａも、図６に示すように、前記同様の上枠２ａ、回動枠２０ａ、および滑り材４０を備えている。
上記上枠２ａが前記上枠２と相違するのは、図６に示すように、垂直な前記化粧片４に替えて、下側の縦片４ａと中間の横片１０と上側の縦片１２とを有し、且つ開口部Ｋの上辺であるフレームｆとの間に凹溝１４を形成していることである。係る凹溝１４内には、例えば、Ｓｉコーキングなどの防水用のシール材ｓが充填される。 FIG. 6 is a partial vertical cross section showing a closed state of the opening / closing device 1a of the flip-up door D having a different form. As shown in FIG. 6, the door D opening and closing device 1 a also includes the same upper frame 2 a, rotating frame 20 a, and sliding material 40 as described above.
The upper frame 2a is different from the upper frame 2 in that, instead of the vertical decorative piece 4, as shown in FIG. 6, a lower vertical piece 4a, an intermediate horizontal piece 10 and an upper vertical piece 12 are used. And the concave groove 14 is formed between the upper side of the opening K and the frame f. The recessed groove 14 is filled with a sealing material s for waterproofing such as Si caulking, for example.

また、上記回動枠２０ａが前記回動枠２０と相違するのは、図６に示すように、前記水平片２３に替えて、内外一対の水平な凸条２３ａ，２３ｂを対向して設け、これらと取付片２１，２２との間に形成される内外一対の段部２４ａ，２４ｂにより前記扉Ｄの上辺部を位置決めしている。しかも、前記中空部２７に変わって、前記扉Ｄの上端面に連通する半中空部２７ａとなるため、当該回動枠２０ａの軽量化にも寄与し得る。
更に、図６に示すように、上記回動枠２０ａにおいて、互いに離れている回動片３０の外側面３１の下端と、勾配片２６の上端との間には、前記段部２８が形成されず、これに替えて、上記外側面３１と勾配片２６の表面とを連続させる緩い湾曲面２８ａが形成されている。
以上のような扉Ｄの開閉装置１ａによっても、前記扉Ｄの開閉装置１と同様な作用が成され、且つ同様な効果を得ることが可能である。

The upper side portion of the door D is positioned by a pair of inner and outer step portions 24a, 24b formed between these and the mounting pieces 21, 22. And since it becomes the semi-hollow part 27a connected to the upper end surface of the said door D instead of the said hollow part 27, it can also contribute to the weight reduction of the said rotation frame 20a.
Further, as shown in FIG. 6, the step portion 28 is formed between the lower end of the outer surface 31 of the rotating piece 30 and the upper end of the gradient piece 26 which are separated from each other in the rotating frame 20 a. Instead of this, a loose curved surface 28a is formed to connect the outer surface 31 and the surface of the gradient piece 26 continuously.
The door D opening / closing device 1a as described above can perform the same operation as the door D opening / closing device 1 and can obtain the same effect.
Note that only the upper frame 2 a may be applied to the opening / closing device 1 instead of the upper frame 2, or only the rotating frame 20 a may be applied to the opening / closing device 1 instead of the rotating frame 20. good.

図７は、更に異なる形態の跳ね上げ扉Ｄの開閉装置１ｂの閉鎖状態を示す部分垂直断面である。上記扉Ｄの開閉装置１ｂも、図７に示すように、前記同様の上枠２ｂ、回動枠２０ｂ、滑り材４０ｂ、および水切り材５０を備えている。
上枠２ｂが前記上枠２と相違するのは、軸受片６の下側面に前記凹部８がない反面、係る軸受片６の下側面と外側面との間に、外向き段部８ｃを形成していること、および外側面に水切り用の段部５ｂを突設していることである。
また、滑り材４０ｂが前記滑り材４０と相違するのは、摺動片４６が上記軸受片６の下側面の全体に沿って隣接するように外側に延出していること、および係る摺動片４６の先端に先端部４７ａを上向きに突設していることである。係る先端部４７ａは、上記上枠２ｂの外向き段部８ｃに係止される。
更に、回動枠２０ｂが前記回動枠２０と相違するのは、勾配片２６の外側寄りの位置から垂直に凸条２６ａが立設すると共に、係る勾配片２６と外側の取付片２２とが直に接続されている反面、これらの間における前記斜め部３８および水切部３９からなる水切片３７を有していないことである。 FIG. 7 is a partial vertical cross section showing a closed state of the opening / closing device 1b of the flip-up door D of a different form. As shown in FIG. 7, the door D opening and closing device 1 b also includes the same upper frame 2 b, rotating frame 20 b, sliding material 40 b, and draining material 50 as described above.
The upper frame 2b is different from the upper frame 2 in that the recess 8 is not formed on the lower surface of the bearing piece 6, but an outward stepped portion 8c is formed between the lower surface and the outer surface of the bearing piece 6. And a draining step 5b is provided on the outer surface.
The sliding member 40b is different from the sliding member 40 in that the sliding piece 46 extends outward so as to be adjacent along the entire lower surface of the bearing piece 6, and the sliding piece. In other words, the tip end portion 47 a protrudes upward from the tip end of 46. The leading end 47a is locked to the outward stepped portion 8c of the upper frame 2b.
Further, the rotation frame 20b is different from the rotation frame 20 in that the ridges 26a are erected vertically from a position closer to the outside of the gradient piece 26, and the gradient piece 26 and the outer mounting piece 22 are provided. Although it is directly connected, it does not have the water section 37 composed of the oblique portion 38 and the draining portion 39 between them.

加えて、係る開閉装置１ｂで新たに用いられた水切り材５０は、図７に示すように、前記同様の押出形材からなり、回動枠２０ｂにおける外側の取付片２２の外側面に隣接する縦片５１、勾配片２６の上方に位置し且つ上向きの湾曲面５８を有する湾曲片５７、係る湾曲片５７の外端部５９から垂下し且つ内側面に凸条２６ａが接触する壁片５５、係る壁片５５の下端部と縦片５１の上端部とから斜め外上向きに延びた斜め片５３と、係る斜め片５３と壁片５５との間に位置し且つ斜め外向きに開口する凹溝５６と、を図示の全長に沿って有している。尚、上記斜め片５３の先端には、斜め下向きの凸条５４が突設されている。
本跳ね上げ扉Ｄの開閉装置１ｂを得るには、図７に示すように、開口部Ｋのフレームｆに上枠２ｂの固定片３をボルトｂ１により固定する。係る上枠２ｂの先端面６ａを含む軸受片６、軸受面７、および凸部９には、予め、滑り材４０ｂの摺動片４６、第２緩衝片４５，円弧片４２、および第１緩衝片４４が嵌着され、且つ上枠２ｂの外向き段部８ｃには、滑り材４０ｂの４７ａが係止されている。 In addition, as shown in FIG. 7, the draining material 50 newly used in the switchgear 1b is made of the same extruded shape as described above, and is adjacent to the outer surface of the outer mounting piece 22 in the rotating frame 20b. A vertical piece 51, a curved piece 57 positioned above the gradient piece 26 and having an upwardly curved surface 58, a wall piece 55 depending from the outer end 59 of the curved piece 57 and contacting the ridge 26a on the inner side surface; An oblique piece 53 extending obliquely outward and upward from the lower end portion of the wall piece 55 and the upper end portion of the vertical piece 51, and a concave groove located between the oblique piece 53 and the wall piece 55 and opening obliquely outward. 56 along the entire length of the figure. Note that an obliquely downward projecting ridge 54 projects from the tip of the oblique piece 53.
In order to obtain the opening / closing device 1b of the flip-up door D, as shown in FIG. 7, the fixing piece 3 of the upper frame 2b is fixed to the frame f of the opening K with bolts b1. The bearing piece 6 including the front end surface 6a of the upper frame 2b, the bearing surface 7, and the convex portion 9 are previously provided with the sliding piece 46, the second buffer piece 45, the arc piece 42, and the first buffer piece of the sliding material 40b. The piece 44 is fitted, and 47a of the sliding member 40b is locked to the outward stepped portion 8c of the upper frame 2b.

一方、図７に示すように、跳ね上げ扉Ｄの上端には、回動枠２０ｂにおける内外一対の取付片２１，２２間の凹溝２４に当該扉Ｄの上辺部を挿入することにより、該回動枠２０ｂが配置される。係る回動枠２０ｂの勾配片２６の上に水切り材５０の湾曲片５７を載置し、係る湾曲片５７の先端部を段部２８に突き当て、該回動枠２０ｂの凸条２６ａの外側面に壁片５５を接触させると共に、取付片２２の外側面に水切り材５０の縦片５１を接触させる。係る状態で、ボルトｂ２を上記縦片５１、取付片２２、跳ね上げ扉Ｄ、および取付片２１に対し、内外方向に沿って貫通させ、その雄ネジ部に袋ナットｎをネジ結合することによって、回動枠２０ｂと水切り材５０とを扉Ｄの上辺に沿って固定できる。この際、水切り材５０の凹溝５６の両端は、扉Ｄの両縦面の外側に向かって開口している。
以上によって、跳ね上げ扉Ｄの開閉装置１ｂが構成され、且つ開口部Ｋを内側（ＩＮ）と外側（ＯＵＴ）とに区画する閉鎖状態とすることができる。 On the other hand, as shown in FIG. 7, at the upper end of the flip-up door D, the upper side of the door D is inserted into the concave groove 24 between the pair of inner and outer mounting pieces 21 and 22 in the rotating frame 20b. A rotating frame 20b is arranged. The curved piece 57 of the draining material 50 is placed on the gradient piece 26 of the rotating frame 20b, the tip of the curved piece 57 is abutted against the stepped portion 28, and the outside of the ridge 26a of the rotating frame 20b. The wall piece 55 is brought into contact with the side surface, and the vertical piece 51 of the draining material 50 is brought into contact with the outer surface of the attachment piece 22. In such a state, by passing the bolt b2 through the vertical piece 51, the attachment piece 22, the flip-up door D, and the attachment piece 21 along the inner and outer directions and screwing the cap nut n to the male screw portion. The rotating frame 20b and the draining material 50 can be fixed along the upper side of the door D. At this time, both ends of the recessed groove 56 of the draining material 50 are open toward the outside of both vertical surfaces of the door D.
As described above, the opening / closing device 1b of the flip-up door D is configured, and the opening K can be in a closed state in which the opening K is divided into the inside (IN) and the outside (OUT).

次いで、前記開閉装置１ｂにおいて、跳ね上げ扉Ｄの下辺中央部の持ち手（図示せず）を掴み、回動枠２０ｂの軸部３３を回転中心として、図８中のカーブした矢印で示すように、上記扉Ｄを外側（ＯＵＴ）の斜め上方に持ち上げる。
その結果、図８に示すように、回動枠２０ｂを含む跳ね上げ扉Ｄは、前記垂直姿勢から斜め上方に約１２０度回転（跳ね上げ）し、開口部Ｋが開放状態となるため、積み荷の出し入れなどが可能となる。
図８に示す開放状態にした際、回動枠２０ｂは、そのストッパ片３４の内側面３６が、滑り材４０ｂの第２緩衝片４５に面接触した位置で停止し、回動枠２０ｂの回動片３０の外側面３１は、滑り材４０の摺動片４６に面接触している。同時に、水切り材５０の湾曲片５７の外端部５９が上枠２ｂの縦片５の外側面に線接触することで、該回動枠２０ｂを含む扉Ｄの回転が停止する。 Next, in the opening / closing device 1b, a handle (not shown) at the center of the lower side of the flip-up door D is gripped, and as indicated by a curved arrow in FIG. Then, the door D is lifted obliquely upward on the outside (OUT).
As a result, as shown in FIG. 8, the flip-up door D including the rotation frame 20b rotates (splashes up) about 120 degrees obliquely upward from the vertical posture, and the opening K is in an open state. Can be taken in and out.
In the open state shown in FIG. 8, the rotating frame 20b stops at a position where the inner surface 36 of the stopper piece 34 is in surface contact with the second buffer piece 45 of the sliding member 40b, and the rotating frame 20b rotates. The outer surface 31 of the moving piece 30 is in surface contact with the sliding piece 46 of the sliding member 40. At the same time, the outer end portion 59 of the curved piece 57 of the draining material 50 makes line contact with the outer surface of the vertical piece 5 of the upper frame 2b, so that the rotation of the door D including the rotating frame 20b is stopped.

以上のような跳ね上げ扉Ｄの開閉装置１ｂによれば、前記扉Ｄの開閉装置１と同様な効果を奏し得る共に、更に扉Ｄの閉鎖時において、水切り材５０の凹溝５６に進入した雨水は、該凹溝５６の両端部の開口部から外側へ逐次排水されるので、雨水の流下や滴下に伴う扉Ｄの外側面におけるシミを生じにくくすることができる。加えて、上枠２ｂの縦片５の外側面に、回動枠２０ｂの外端部５９を受け入れる前記段部５ｂを設けたことで、該段５ｂにより水切りされた雨水を上記凹溝５６内に滴下できるので、上枠２ｂの縦片５および軸受片６の外側面に雨水の流下によるシミの付着を防ぐことができる。
しかも、前記滑り材４０ｂの摺動片４６と、水切り材５０の湾曲片５７との隙間を内外方向に沿って細長く且つ小さくしているので、雨水や塵埃の内側（ＩＮ）への浸入を一層抑制することができる。 According to the opening / closing device 1b of the flip-up door D as described above, the same effect as that of the opening / closing device 1 of the door D can be obtained, and further, the door D enters the concave groove 56 of the draining material 50 when the door D is closed. Since rainwater is sequentially drained from the openings at both ends of the concave groove 56 to the outside, it is possible to make it difficult to cause a stain on the outer surface of the door D due to the rainwater flow or dripping. In addition, by providing the step portion 5b that receives the outer end portion 59 of the rotating frame 20b on the outer side surface of the vertical piece 5 of the upper frame 2b, rainwater drained by the step 5b can be contained in the concave groove 56. Therefore, it is possible to prevent spots from adhering to the outer surface of the vertical piece 5 and the bearing piece 6 of the upper frame 2b due to the rain water flowing down.
Moreover, since the gap between the sliding piece 46 of the sliding material 40b and the curved piece 57 of the draining material 50 is elongated and small along the inner and outer directions, it is possible to further infiltrate rainwater and dust into the inside (IN). Can be suppressed.
