A hinge for a revolving door that closes a cavity toward the depth side of a wall surface in an existing house is a common hinge extending between the upper surface and the lower surface of the cavity. A single hinge shaft is inserted in a series at the end joint structure, and the hinge shaft is attached to a hinge mounting seat whose upper and lower ends are fixedly attached to the upper and lower surfaces of the cavity from the outside. The door can open and close the cavity to the depth side of the house wall. Therefore, efficient storage in the existing cavity in the house can be realized. Moreover, the high rigidity of a hinge structure can be obtained by the end part contact structure of the cylindrical part which comprises a hinge part, and smooth rotation operation | movement can be obtained even if a rotation part becomes heavy.

  According to a second aspect of the present invention, there is provided a rotary opening and closing device according to the invention described above, wherein the hollow portion is formed in a close-up portion in an existing house.

  The operation and effect of the invention of claim 2 will be described. In a Japanese-style house or the like, the existing push-in portion is provided with a sliding door type door, but the existing door is removed and the hinge of the end contact structure of the present invention is used. By mounting from the outside, it is possible to realize the maximum increase in storage efficiency by the minimum renovation in the existing house.

  FIG. 1 shows a horizontal section of a closet portion in a Japanese style house, and pillars at four corners of the closet portion are shown as 1-1, 1-2, 1-3, 1-4. The left and right walls of the closet are shown as 2-1, 2-2, the back wall is shown as 2-3, and the top and bottom are shown as 2-4, 2-5 (see also Figs. 2 and 3). In Japanese-style houses, etc., there is usually a sliding door type door between the front pillars 1-1 and 1-2. In this invention, the sliding door type door in the front of the close-up part in such a normal Japanese-style house is removed, and as a result, the close-in part remains as a hollow part 4 (FIG. 2) opened toward the back on the wall surface of the house, The hollow portion 4 is opened and closed by a hinged rotary door (rotary member of the present invention).

  As shown in FIG. 1, the push-in cavity 4 obtained by removing the sliding door type door is configured to be opened and closed by two pairs of right and left rotating doors 12A and 12B each having a hinge. Yes. The revolving doors 12A and 12B are provided with storage shelves 22A and 22B on the back side in order to further improve the storage efficiency. That is, when the revolving doors 12A and 12B are closed, the storage shelves 22A and 22B are hidden in the closet, but around the upright hinge shaft 24 (extending in the direction perpendicular to the paper surface of FIG. 1) The storage shelves 22A and 22B can be accessed by opening 12B (the open state of one revolving door is indicated by an imaginary line 22 'in FIG. 1).

  The hinge shaft 24 for rotating the revolving doors 12A and 12B extends between the upper wall surface 2-4 and the lower wall surface 2-5 of the press-in cavity, and the upper and lower ends of the hinge shaft 24 are the upper wall surfaces of the press-in cavity portion as will be described later. 2-4 and the lower inner surface 25 are mounted on opposite inner surfaces. As shown in FIG. 3, a state in which three hinges 30 </ b> A are attached to the right rotating door 12 </ b> A is shown. The upper, middle, lower, and three hinges 30B are similarly attached to the left rotating door 12B. As shown in FIG. 4, the hinge 30A of the right rotating door 12A is fastened to the side plate of the storage shelf 22A integral with the back surface of the rotating door 12A by a wood screw 28 at the plate-like portion 26A. The hinge 30A has a cylindrical portion integrated with the plate-like portion. Similarly, the hinge 30B is also attached to the left rotating door 12B by a wood screw on the side plate of the storage shelf 22B on the back surface of the rotating door 12B at its plate-like portion 26B. The hinge 30B of the left rotating door 12B also forms an integral cylindrical portion. The hinges 30A and 30B in which the plate-like portions 26A and 26B are integrated can be formed by extrusion molding of aluminum or the like.

  The cylindrical portions constituting the hinges 30A, 30B of the rotary doors 12A, 12B are inserted in series on the hinge shaft 24 as shown in FIGS. As shown in FIG. 3, the cylindrical part of the lowermost hinge 30A of the right rotating door 12A, then the cylindrical part of the lowermost hinge 30B of the left rotating door 12B, and then the hinge 30A as the cylindrical part , 30B has the same inner and outer diameters, the cylindrical portion of the hinge 30A in the middle of the right rotating door 12A, the cylindrical portion of the hinge 30B in the middle of the left rotating door 12B, and then again the auxiliary sleeve 32, and the cylindrical portion of the uppermost hinge 30A of the right rotating door 12A, and finally the cylindrical portion of the uppermost hinge 30B of the left rotating door 12B. The hinges 30A and 30B and the auxiliary sleeve 32, which are cylindrically inserted into the hinge shaft 24 in series, are brought into contact with each other at their adjacent end surfaces. This end contact structure is the upper wall surface 2 of the press-in cavity. -4 and the lower wall surface 2-5, forming a pseudo-pipe, combined with the attachment structure of the upper and lower ends of the hinge shaft 24 described below, provides high rigidity of the hinge structure. That is, as will be described later with reference to FIG. 2, the hinge mounting seats 36 and 38 are fixed to the opposing inner surfaces of the upper wall surface 2-4 and the lower wall surface 2-5 of the cavity 4 of the push-in portion. The screws 40 for fixing the hinge mounting seats 36, 38 are screwed into the hinge mounting seats 36, 38 into an internal metal screw sleeve (also referred to as “demon”) 44 having a wood screw type embedded structure. The upper and lower ends 24-1, 24-2 of the hinge shaft 24 form external screws, and the upper and lower hinge mounting seats 36, 38 are formed in the screw holes 36 on the outer screw portions 24-1, 24-2. It is structured to be screwed through -2, 38-2.

  A series of end abutment structures including the cylindrical portion and the auxiliary sleeve 32 are provided with a hinge on the lower side through a resin-free oil-free washer 42 (for example, Oiles type # 80 or # 83 washer manufactured by Oiles Co., Ltd.). It is placed on the mounting seat 38. If necessary, an oil-free washer or bearing member made of resin similar to the washer 42 can be interposed on the contact surface between the hinges 30A and 30B as the respective cylindrical portions. A series of hinges 30A, 30B as a cylindrical portion and an auxiliary sleeve 32 extending between the upper wall surface 2-4 of the press-in cavity and the lower wall surface 2-5 of the press-in cavity so as to constitute one pseudo pipe. The end abutment structure is inserted into the hinge shaft 24 fixed to the metal hinge mounting seats 36 and 38 fixed to the lower surface 2-4 and 2-5 on the upper and lower ends of the press-in cavity, and is cylindrical. Combined with a series of end abutment structures consisting of a part and an auxiliary sleeve 32 received at the hinge mounting seat 38 by a resin-free oilless washer 42 at the lower end, a very rigid hinge mechanism is constructed and rotated. Regardless of the weight of the articles placed on the shelves 12A and 12B on the back of the doors 12A and 12B, stable operation over a long period of time can be compensated for. Incidentally, the openings 36B on the inner and outer sides of the openings 36A and 36B of the hinge mounting seats 36 and 38 through which the demon 44 is inserted have a slot shape with one end opened as shown in FIG. A semi-assembly (subassembly according to the present invention) in which the rear side storage portions 22A and 22B are attached to 12B and hinges 30A and 26B are attached can be attached together with the mounting seats 36 and 38 to the push-in portion of the existing house. Installation efficiency can be significantly increased despite minimal home renovation. This will be described later in more detail.

  As shown in FIG. 7, the metal hinge mounting seat 36 (and the hinge mounting seat 38) protrudes somewhat forward from the front surfaces 2-4A and 2-5B of the upper and lower wall surfaces 2-4 and 2-5 constituting the press-in cavity. For this reason, the upper and lower ends 24-1, 24-2 of the hinge shaft 24 protruding from the hinge mounting seats 36, 38 are in a protruding position. Then, the cap 59 is fitted to the upper and lower ends 24-1 of the hinge shaft 24 protruding from the hinge mounting seats 36, 38. That is, the cap 59 has an opening 59A, and the cap 59 is inserted into the upper and lower ends 24-1 and 24-2 of the hinge shaft 24 through the opening 59A. The width of the cap 59 is just inserted into the gap formed at the opposite end of the revolving doors 12A and 12B when the revolving doors 12A and 12B are closed (this width is equal to the diameter of the cylindrical portion of the hinge and the auxiliary sleeve 32). And the height is equal to the distance between the hinge mounting seats 36, 38 and the lower surface 2-4, 2-5 on the press-in cavity. Therefore, the gap between the rotary doors 12A and 12B can be filled with the cap 59 when the rotary doors 12A and 12B are closed. Therefore, as shown in FIG. 7, in the closed state of the rotary doors 12A and 12B, the press-in cavity can be completely shielded by the rotary doors 12A and 12B. That is, in the closed state of the revolving doors 12A and 12B, the press-in cavity portion 4 cannot be seen from the outside, and the appearance of a wall surface extending from the floor to the ceiling without a gap can be exhibited. In the middle, the cylindrical part constituting the hinge and the auxiliary sleeve 32 and the cap 59 are visible, but since these are the same diameter and the same material (made of aluminum), one pipe extending from the bottom to the top Since it has an appearance, it can have a clean appearance.

  The hinge shaft 24 is fixed to the upper and lower wall surfaces 2-4, 2-5 of the hollow portion 4 obtained by removing the sliding door in the existing close-in only by the metal hinge mounting seats 36, 38 at the upper and lower ends. That is, the upper and lower ends of the hinge shaft 24 are screwed and fixed to the metal hinge mounting seats 36 and 38, and the metal hinge mounting seats 36 and 38 are formed on the upper and lower surfaces 2-4 and 2-5 of the press-in cavity. It is fixed. As shown in FIG. 2, the hinge is assembled by inserting the cylindrical portion constituting the hinge, the auxiliary sleeve 32, and the washer 42 in advance, and connecting the metal hinge mounting seats 36, 38 to the screw portions 24 at the upper and lower ends of the hinge shaft 24. -1, 24-2 screwed into sub-assembly SA. This sub-assembly SA is introduced into the cavity 4 after removing the sliding door in the close-up portion of the existing house from the front to the back as shown by the white arrow in FIG. 2, but prior to that, the screw in FIG. The screw on the back side of 40 is lightly inserted into the demon 44, and the slots 36A and 38A of the metal hinge mounting seats 36 and 38 serve as guides, so that the assembly can be easily introduced into the intended position. This can be performed reliably (see also FIG. 5 for the positional relationship between the screw 40 and the slot 36A). Thereafter, the front screw 40 is also screwed into the corresponding demon 44 and fastened only from the inner surface side with a tool (screw driver), whereby the mounting of the subassembly to the close-in portion of the existing house is completed. In other words, the construction of the hinge can be remarkably simplified by the structure of the present invention.

  In this invention, by opening and closing the cavity obtained by removing the sliding door of the close-up in an existing Japanese-style house, etc., by a rotating member with a hinge attached from the outside, the renovation in the existing house is minimized and the maximum As a result, it is possible to perform an efficient storage, and the aesthetic appearance is not impaired.
