  Hereinafter, preferred embodiments of a hinge device and a fitting according to the present invention will be described in detail with reference to the accompanying drawings.

  FIGS. 1-1 and 1-2 illustrate a door to which a hinge device according to an embodiment of the present invention is applied. The door illustrated here opens and closes an entrance E provided in a wall W partitioning a room in the room, and includes a frame 10 and a door panel (face material) 20. The frame 10 constitutes a rectangular frame opening 14 by disposing an upper frame 11, a lower frame 12, and left and right vertical frames 13 along the four circumferences of the entrance / exit E. The door panel 20 is a rectangular surface material formed to have a size capable of closing the frame opening 14 of the frame body 10. This door panel 20 is centered on an axis set along the vertical direction by interposing hinge devices 30 at a plurality of locations between the prospective surface on the suspension side and one vertical frame 13 of the frame body 10. Is supported by the frame 10 so as to be rotatable.

  As shown in FIGS. 2 and 3, the hinge device 30 includes two upper and lower blades 31 and a hinge shaft 32. The blade 31 is formed by integrally forming a base plate portion 131 having a rectangular flat plate shape and a shaft support portion 231 provided on one side edge of the base plate portion 131 with a metal. The substrate part 131 is a part attached to the door panel 20 or the vertical frame 13. The board portion 131 is provided with a plurality of screw insertion holes 131a for inserting screws at appropriate positions. The shaft support portion 231 has a cylindrical shape having the same height as the substrate portion 131. A shaft support portion 231 of a blade plate disposed below (hereinafter referred to as “lower blade plate 31” when distinguished) is provided with a shaft fitting hole 231a, and a blade plate disposed below (hereinafter referred to as distinction). In this case, the shaft support portion 231 of the “upper blade 31” is provided with a shaft insertion hole 231b. The shaft fitting hole 231 a and the shaft insertion hole 231 b are holes having a circular cross section provided in the center portion of the shaft support portion 231, and open only on one end surface 232 of each shaft support portion 231. The shaft fitting hole 231a is formed to have a smaller inner diameter than the shaft insertion hole 231b. The hinge shaft 32 has a cylindrical shape having an outer diameter that can be fitted into the shaft fitting hole 231a. The hinge shaft 32 is fixed to the shaft support portion 231 by mounting one end portion of the hinge shaft 32 in the shaft fitting hole 231a of the lower blade plate 31, and the other end portion to the shaft insertion hole 231b of the upper blade plate 31. It is slidably inserted. Although not clearly shown in the drawing, a portion of the hinge shaft 32 protruding from the shaft support portion 231 of the lower blade 31 is coated with grease for lubrication with the inner peripheral surface of the shaft insertion hole 231b. .

  A collar member 40 is disposed between the shaft support portion 231 of the lower blade 31 and the shaft support portion 231 of the upper blade 31. The collar member 40 is formed in an annular shape from a resin material having wear resistance such as polyacetal or ethylene-tetrafluoroethylene. In the present embodiment, a collar member 40 having an outer diameter equivalent to that of the shaft support portion 231 and having an inner diameter through which the center hole 41 can pass through the hinge shaft 32 is applied.

  In the collar member 40, a plurality of through holes 42 are formed from one end surface 40a to the other end surface 40a. As shown in FIGS. 2, 3-1, 3-2, the through-hole 42 is a fine hole having an inner diameter of about 1/10 of the center hole 41 and having a circular cross section. In the present embodiment, a total of twelve through-holes 42 are formed at four locations on three circumferences having different diameters on the end surface 40a of the collar member 40, respectively. The through holes 42 formed on the respective circumferences are provided at equal intervals. The through hole 42 provided on the innermost circumference and the through hole 42 provided on the central circumference are arranged so as to be shifted by 45 °, and further, the through holes provided on the central circumference are provided. The hole 42 and the through hole 42 provided on the outermost circumference are arranged so as to be shifted by 45 °.

  In order to allow the frame 10 to support the door panel 20 by the hinge device 30 configured as described above, for example, the upper 131 is removed from the hinge shaft 32 and the substrate 131 of the upper blade 31 is placed on the prospective surface of the door panel 20. Then, the board portion 131 of the lower blade 31 is screwed to the prospective surface of the vertical frame 13. A collar member 40 is inserted in advance through the hinge shaft 32 protruding upward from the shaft support portion 231 of the lower blade 31. If the door panel 20 is suspended so that the hinge shaft 32 is inserted into the shaft insertion hole 231 b of the upper blade 31 attached to the door panel 20 from this state, the shaft support portion 231 of the upper blade 31 is lowered through the collar member 40. The shaft support part 231 of the upper blade 31 and the shaft support part 231 of the lower blade 31 are in contact with the shaft support 231 of the blade 31 and are supported so as to be relatively rotatable about the hinge shaft 32. Thereby, the door panel 20 is rotatably supported by the frame 10 around the hinge shaft 32, and the doorway E can be opened and closed.

  As described above, the collar member 40 is interposed between the shaft support portion 231 of the upper blade 31 and the shaft support portion 231 of the lower blade 31. Therefore, even when the shaft support portion 231 rotates relative to the opening and closing of the door panel 20, the metal portion does not slide directly, and the generation of abnormal noise can be prevented and the door panel 20 can be opened and closed. Does not require great power to operate. Moreover, since the collar member 40 is provided with a plurality of through holes 42, when the grease applied to the hinge shaft 32 hangs downward, these through holes 42 function as an oil sump. The grease can be always kept between the end surface 40a of the collar member 40 and the end surface 232 of the shaft support portion 231 while preventing leakage to the periphery of the shaft support portion 231. As a result, there is no risk of grease leaking out around the collar member 40 and adhesion of dust, the appearance of the door can be maintained, and the situation in which the collar member 40 is worn early can be prevented. Thus, it is possible to maintain a smooth opening / closing operation of the door panel 20.

  The shape of the through hole 42 formed in the collar member 40 is not necessarily limited to a circular cross section. For example, as in Modification 1 shown in FIGS. 5A and 5B, the through holes 142 having a groove shape along a circular arc concentric with the center hole 141 through which the hinge shaft 32 passes are formed on both end surfaces 140a of the collar member 140. You may make it form over. Further, as in Modification 2 shown in FIGS. 6A and 6B, the through holes 242 are formed over both end surfaces 240a of the collar member 240 so as to communicate with the inner peripheral surface of the center hole 241 through which the hinge shaft 32 passes. Even if formed, the same effects can be obtained. In the second modification shown in FIGS. 6A and 6B, the through hole 243 having a groove shape along the arc is not necessarily provided.

  Furthermore, the oil sump of the collar member 40 does not necessarily need to be configured by a through hole. For example, as in Modification 3 shown in FIGS. 7-1 and 7-2 and Modification 4 shown in FIGS. 8-1 and 8-2, the oil sump is formed by forming a recess in the end face of the collar member. It is also possible to do. That is, in Modification 3 shown in FIGS. 7-1 and 7-2, a plurality of groove-like recesses 342 are formed on the end face 340a of the collar member 340 along a circular arc concentric with the central hole 341 through which the hinge shaft 32 passes. By doing so, an oil sump is constructed. Further, in Modification 4 shown in FIGS. 8A and 8B, a plurality of spiral groove-shaped recesses 442 extending from the center hole 441 through which the hinge shaft 32 penetrates to the end surface 440a of the collar member 440 are formed. Constitutes an oil sump. The spiral groove-shaped recess 442 has an inner peripheral end that reaches the center hole 441, but an outer peripheral end terminates in the end surface 440a.

  Thus, even when the collar members 340 and 440 are provided with the recesses 342 and 442, the grease drooping below the hinge shaft 32 is caused by the recesses 342 and 442 to end surfaces 340 a and 440 a of the collar members 340 and 440. And the end face 232 of the shaft support portion 231 of the upper blade 31. As a result, there is no risk of grease leaking around the collar members 340 and 440, and dust can be adhered, the appearance of the door can be maintained, and the situation where the collar members 340 and 440 are worn early can be prevented. Thus, the door panel can be smoothly opened and closed over a long period of time.

  In the case where the oil sump is formed by forming the recesses 342 and 442, it is sufficient that the collar members 340 and 440 are formed only on the end surfaces 340a and 440a facing the shaft support portion 231 of the upper blade 31. However, when the concave portions 342 and 442 are formed in the both end faces 340a and 440a of the collar members 340 and 440, respectively, as in the modified examples 3 and 4, the orientation of the collar members 340 and 440 is confirmed at the time of assembly. This eliminates the need for the assembly work.

  In addition, in embodiment mentioned above and the modification 1-the modification 4, although the hinge shaft 32 has illustrated the fittings arrange | positioned along an up-down direction, the hinge shaft 32 is arrange | positioned along a horizontal direction. Of course, it can also be applied to joinery.

  Moreover, although the hinge apparatus arrange | positioned so that the blade 31 may shift | deviate in the direction of the hinge axis | shaft 32 is illustrated, it is not necessarily limited to this. For example, the present invention can also be applied to a hinge device configured such that two blades 51 open and close each other as in Modification 5 shown in FIG. That is, a plurality of shaft support portions 251 are arranged alternately on one side edge of the substrate portion 151 having a rectangular plate shape, and a hinge shaft (not shown) is arranged over the shaft support portions 251. The two blades 51 are supported so as to be relatively rotatable around a hinge shaft (not shown). For this hinge device, the collar member 540 may be disposed between all the shaft support portions 251 arranged side by side, or the collar member 540 is provided only between the specific shaft support portions 251. It doesn't matter. As the oil sump for the collar member 540, any one of the above-described embodiment or Modifications 1 to 4 may be applied.
