This is achieved by fitting the upper part of the more protruding core rod 5a.

Hereinafter, each adjustment will be described. Referring to FIGS. 1 and 2 (a), the upper hinge member 2 is vertically adjusted by inserting a turning tool such as a screwdriver into the opening 7c of the lower lid 7 to move the movable member 6 to the bottom cross. By rotating the groove to move the inside of the cylindrical body 3b up and down, the shaft core 5 on which the core rod 5a is mounted on the movable member 6 can be continuously adjusted in the vertical direction. On the other hand, when it is not necessary to move the shaft core up and down at all, as shown in FIG. 5, the shaft core 51 is inserted from the upper end of the cylindrical body 2b through the upper part of the cylindrical body 3b, and is inserted into the upper cover 51b of the core rod 51a.

The length L which is twice the eccentric position can be adjusted steplessly to the left end position of the upper hinge member 2 shown in FIG.

The angle of the upper hinge member 2 in the front-rear direction can be adjusted by
4A shows a case where the rear side of the upper blade 2a of the upper hinge member 2 forms an inclination angle α with respect to the front side of the base 10a of the base 10, and FIG. In this case, the rear side of the upper blade 2a is parallel to the upper blade 2a. Base 10
a The upper blade 2a is superimposed on the front supporting portion 10g, and three nuts 12 are provided in each of the semicircular grooves 10h, 10h and 10i.
And the nut 1 is inserted through the through holes 10e, 10e and 10f from the front side of the three angle adjusting holes 2c of the upper blade 2a.
For example, a fixing tool 14 is screwed into the female screw 2 by turning a turning tool such as a screwdriver, and in FIG. 3A, a nut is formed so that the rear side of the upper blade 2a forms a rightward downward inclination angle α with respect to the front side of the base 10a. The nut 12 is fixed to the semicircular grooves 10h, 10h, and 10i. At this time, the rear side of the nut 12 forms a rightward downward inclination angle α with respect to the rear side of the base 10a. On the other hand, in (b), the rear side of the upper blade 2a is fixed in a parallel position to the front side of the base 10a, and the rear side of the nut 12 is the base 1
0a is parallel to the rear side. In any case, the fixing tool 1 is fitted into the semicircular grooves 10h, 10h, and 10i by adjusting the contact direction with the arc surface of the nut 12 and fitted into the screw hole of the nut 12.
4 is screwed and fixed, so that the inclination angle α can be adjusted steplessly, and the bottom surface of the head of the fixing tool abuts on the rear side of the upper blade plate 2a at a right angle, so that an unreasonable load is not applied to the female screw of the nut 12. The angle of the upper hinge member 2 in the front-rear direction can be repeatedly adjusted. Similarly, it is also possible to set the inclination angle α so that the rear side of the upper blade 2a rises to the right.

The angle adjustment of the upper hinge member 2 in the up-down direction, the left-right direction, and the front-rear direction can be easily adjusted with only a turning tool such as a screwdriver. The lower hinge member 3 is fixed to an optimal state corresponding to the dimensional variation on the frame side, and fixed to the door (not shown) through the fixing tool 14 through the four fixing holes 10d of the base 10. By fixing the hole 3c to the frame (not shown) through the fixing tool 14, it is possible to function as a hinge. Usually, a pair of hinges are used in combination vertically, but in this case, hinges equipped with a shaft core 5 shown in FIG. 1 and FIG. Shaft core 5 shown in FIG.
It is preferred to use a hinge with 1 on top. Each adjustment of the vertical direction, the horizontal direction, and the front-rear direction angle of the upper hinge member 2 may be performed independently, respectively.
They may be mounted in combination. The cross groove engraved on the head of the fixing member 14 and the lower bottom surface of the movable member 6 is not limited to the most convenient one, and may be a minus groove, a polygonal groove, or the like.

[0015]

According to the hinge of the present invention, each adjustment of the horizontal position, the vertical position, and the front-rear direction angle can be performed individually or in combination of two or three in spite of the simple structure. It can be used diversified according to the variation in dimensions on the door side and the frame side.
