Description

  The present invention relates to a door having a structure in which a hinge portion circulates along opposing surfaces of pillars each having a substantially circular section. In particular, the present invention relates to a door which has improved the conventional drawbacks and made it practical. The door of the present invention is used for various facilities such as buildings, houses, stores, factories, hotels, restaurants, showrooms, boutiques, or doors, doors, folding folding doors, shutters, screen doors, partitions, etc. in buildings. So you can create a comfortable space.

  The “door” in the present invention may be used in a broad sense including the door, door, foldable folding door, rain door, screen door, partition, door, gate, box cover, and the like. Moreover, the casket which comprises the door in this invention may be used for the wide meaning including shojis, such as a vertical fence, a recumbent board, and the glass, a board | plate, and a net | network enclosed by these.

  In the conventional hinge structure, when the door is opened, the distance between the frame and the door is greatly separated. Therefore, when the door is closed, there is an accident that a finger or an object is caught. The solution to the accident is to ensure that the frame and door, and the door and door vertical members approach or touch each other. However, a door structure with no gap between them cannot be put into practical use unless many problems of conventional doors are solved. For example, a door with a width of 850 mm is said to have a pressure of about 600 kg sandwiched between its suspenders, and safety is required.

  Conventionally, in a door that can be opened and closed, the hinge bracket is separate from the door body and is not integrally formed, and the hinge bracket itself is opened and closed independently of the door. For example, a standing frame attached to the surrounding wall supports the weight of the door through a hinge fitting. The doors to which the doors are continuously attached require support for performing mutual weight and rotation on the doors through hinge fittings attached to the vertical frame side. Therefore, since the door may not be supported by the hinge metal fitting alone due to its weight, it is necessary to hang it from the upper frame, support it with the lower frame, or separately provide additional hardware dedicated to support.

  The doors and the like receive the entire weight as a shear load by the hinge fittings. Therefore, when the small hinge metal fitting is attached to the door or the like, a large shear strength is required. In the door or the like to which the hinge fitting is attached, the center of rotation when opening and closing is on the shaft connecting the hinge fittings, and is generally outside the door thickness. Further, a door or the like to which the hinge fitting is attached is subjected to a bending moment due to the weight of the door, and a shear load is irregularly applied to the hinge fitting during opening and closing.

  As for the door etc., the axis | shaft of an upper and lower hinge metal fitting may not pass by the position shift of attachment or the twist deformation | transformation of a door. Since the weight of the door is likely to be applied to either the upper or lower side, an excessive load is easily applied to the hinge fitting when the door is opened and closed, and rattling or squeak noise may occur. Moreover, the rotation center axis | shaft of the hinge etc. with which the said door etc. are attached is on the outer side of door thickness, and a door will rotate large only the part which it takes out. If the door has a large space, there is a case where construction is difficult or there is a problem in opening and closing when there is not enough space.

  FIG. 22 is a view for explaining a conventional hinge fitting. For example, the hinge fitting 221 inserts the door attachment portions 2211 and 2212, attachment holes 2213 and 2214 provided in the door attachment portions 2211 and 2212, the rotation shaft 2215, and the rotation shaft 2215 to rotate the door. The shaft insertion holes 2216 and 2217 are configured to be movable. Doors not shown are respectively attached to the mounting holes 2213 and 2214 of the hinge fitting 221 by screws.

  The door mounting portions 2211 and 2212 are provided with shaft insertion holes 2216 and 2217 for inserting the rotation shaft 2215 so as to alternate with each other. The rotary shaft 2215 is inserted into the shaft insertion holes 2216 and 2217 from above, so that the doors attached to the door attachment portions 2211 and 2212 can be opened and closed.

  “Glasses-type hinge parts” in Japanese Utility Model Laid-Open No. 50-140822 is a hinge facing a foldable container or a cargo container, and is a connecting part that allows the angle of a fence or a partition to be freely set.

  The belt hinge in Japanese Utility Model Laid-Open No. 56-155074 has two strips fixed to two standing frame members in an S-shape. The belt hinge can be opened and closed only about 90 degrees. Not only is it difficult for the band hinge to prevent the band from being loosened, but when the door is frequently opened and closed, the problem of loosening of the band hinge has not been solved.

Japanese Patent Application Laid-Open No. 2004-107996 discloses a flexible panel cooperation structure in which flexible strips are wound in an S-shape that is staggered and the ends of the top and bottom strips are mutually connected. It is composed of hinges that are made by connecting to.
Japanese Utility Model Publication No. 50-140822 Japanese Utility Model Publication No. 56-155074 JP 2004-107996 A

  A door connected by a conventional hinge metal fitting, for example, a door, a door, a foldable open / close rain door, and a screen door (hereinafter simply referred to as a door) has a center of rotation at a rotating shaft 2215 portion of the hinge metal fitting 221, and the structure or There is a case where it cannot be rotated 180 degrees depending on the place, and there is a disadvantage that a gap is always generated between the doors. In the connecting structure of panels that can be bent and stretched as described in JP-A-2004-107996, a gap between two doors is generated by the thickness of the strip.

  The door having the above-described structure has a disadvantage that not only the wind passes but also the other can be seen from one side. In addition, the hinge using the S-shaped belt member has a limitation that the vertical shaft of the adjacent door must be passed first, and that the hinge repair work must be performed after removing the panel material of the door. there were.

  In particular, aluminum alloy sashes have increased in recent years, and folding doors, screen doors, partitions, etc. made of the same material as the sashes have come to be used in various facilities such as hotels, restaurants, showrooms, boutiques, etc. I came. However, the gap between the doors has become a decisive drawback for a door, in which a finger is caught. Moreover, since the thing using the 8-shaped belt member described in the said gazette does not solve the problem of the gap generated between the doors, and the problem such as the installation of the recumbent, as a folding door, Not realized.

  Those using the eight-shaped band member described in the above publication cannot be fitted with a reed made of aluminum alloy or the like. In addition, the one using the eight-shaped band member described in the above publication is a structure that completes the door connection at the factory, so many doors are integrated, heavy, difficult to handle, It was not made in consideration of problems such as assembly and transportation. Furthermore, there is a problem that the repair of the hinge is a large-scale work that cannot be performed unless the entire connecting door is removed from the frame and the face material (panel material) of the door is removed. In addition, the flexible panel connecting structure described in Japanese Patent Application Laid-Open No. 2004-107996 winds flexible strips in an S shape so as to be alternately staggered, and The ends are connected to each other to form an “eight-shaped hinge”, and two poles having a semicircular cross section are inserted into the two holes of the “eight-shaped”, opposite to the semicircular shape. This is a connection structure in which the end portion is fastened in the concave portion of the side panel fixing surface side end surface. The readjustment and repair that maintain the tightening performance of the “8-shaped hinge” cannot be performed because the work of the tool such as a screwdriver is obstructed by the face material of the panels. Therefore, the pole and the panel can only be separated. Further, the disassembling work after construction is blocked by the ceiling, floor, and wall, and the pole does not come out of the “8-shaped”. The connection structure of the hinge and the pair of non-separable poles is difficult for a door having a large volume or weight or a continuous folding door because all panels are removed from the building in use for each readjustment or repair. It was. The "8-shaped hinge" pole is optimal when the panel is lightweight and the hardware is made of wood that can be fixed with screws anywhere on the end of the panel. For example, the invention is suitable for wooden or plywood closets. However, it cannot be used in the case of an aluminum frame frame structure. Moreover, the thing of the said invention has many fatal flaws for aluminum sashes.

  In order to solve the problems as described above, an object of the present invention is to provide a door that completely eliminates a gap between the doors and considers actual production and construction. Another object of the present invention is to provide a door that is improved in connection with it because it is found that it is not always necessary to rotate 360 degrees in a door that connects and folds a plurality of the doors. An object of the present invention is to provide a door capable of preventing injury because a finger is pinched (inserted) or pushed out as a structure in which there is no gap between hinge fittings connecting the doors.
