  The hinge body 4 is attached to the body 2. The adjustment member 11 is supported by the hinge body 4 so as to be rotatable around the pivot axes P1 to P3. The adjusting screw 13 is screwed into the adjusting member 11 and is attached to the hinge body 4 so as to be rotatable and not movable in the axial direction. For this reason, when the adjusting screw 13 is turned, the adjusting member 11 rotates around the pivots P1 to P3. As the adjustment member 11 rotates around the pivots P1 to P3, the door 3 moves in the left-right direction.

  Here, the rotation of the adjustment member 11 tends to change the gap δ between the main body 2 and the door 3. The change in the gap δ is suppressed by changing the positions of the pivots P1 to P3 of the adjustment member 11 (that is, the rotation center of the adjustment member 11). The long hole 11b1 of the adjusting member 11 and the long hole 4b2 of the hinge body 4 are inclined in opposite directions. The pivots P1 to P3, which are the rotation centers of the adjusting member 11, are defined by the intersections of a line L1 perpendicular to the long hole 11b1 through the axis 14 and a line L2 perpendicular to the long hole 4b2 through the axis 15. As shown in FIGS. 8 (a) to 8 (c), as the door 3 moves from the left end position to the right end (as the covering amount decreases), the pivot also approaches the main body 2 from P1 to P3. Moving. By moving the pivots P <b> 1 to P <b> 3, the change in the gap of the door 3 can be compensated.

  As shown in FIG. 7A, the adjustment member 11 projects forward from the main body 2 when the door 3 is closed. The adjusting screw 13 to be screwed into the adjusting member 11 is disposed in a portion of the adjusting member 11 protruding from the main body 2 and in the hinge bracket 5. When the cover 9 shown in FIG. 9A is removed from the adjustment member 11, the adjustment screw 13 is exposed from the notch 3 b of the door 3 as shown in FIG. 9B. The position of the door 3 in the left-right direction can be adjusted by engaging the tool passing through the notch 3b with the engaging portion 13e of the adjusting screw 13 and turning the adjusting screw 13 with the tool.

  As shown in FIG. 7B, when the door 3 is opened to 90 °, the hinge bracket 5 is separated from the adjustment screw 13. For this reason, even when the door 3 is opened, the position of the door 3 in the left-right direction can be adjusted by engaging the tool with the engaging portion 13d of the adjusting screw 13 and turning the adjusting screw 13 with the tool. The first link 21 and the third link 23 are formed with notches 21a and 23a for avoiding interference with the tool. As shown in FIG. 7C, even if the door 3 is opened 180 °, the adjustment screw 13 can be turned to adjust the position of the door 3 in the left-right direction.

  10 and 11 show a hinge according to a second embodiment of the present invention. 10 shows a cross-sectional view, and FIG. 11 shows an exploded perspective view. The second embodiment is different from the first embodiment in that an adjustment screw 41 is screwed into the hinge body 4 and attached to the adjustment member 11 so as to be rotatable and not movable in the axial direction. Since other configurations are the same as those of the first embodiment, the same reference numerals are given and description thereof is omitted. Even in the hinge of the second embodiment, the position of the door 3 in the left-right direction can be adjusted by turning the adjusting screw 41.

  The present invention is not limited to the embodiment described above, and can be embodied in other various embodiments without departing from the scope of the present invention. For example, in the above embodiment, the hinge bracket is connected to the adjustment member via the link mechanism, but the hinge bracket can be connected to the adjustment member via the hinge shaft, that is, the hinge can be a single-axis hinge.

  In the above embodiment, only the function of adjusting the left / right direction of the door is added to the hinge. However, in addition to the function of adjusting the left / right direction, a function of adjusting the front / rear direction and / or the vertical direction can be added. In this case, an intermediate member is interposed between the hinge member and the adjustment member. The intermediate member is attached to the hinge body so that the position thereof can be adjusted in the front-rear direction and / or the vertical direction. The adjusting member is attached to the intermediate member so that the position thereof can be adjusted in the left-right direction. The adjusting screw is interposed between the intermediate member and the adjusting member, and rotates the adjusting member around the pivot with respect to the intermediate member. In this case, the hinge body and the intermediate member constitute the first hinge member of the present invention.

  In the above embodiment, when adjusting the position of the door in the left-right direction with the adjusting screw, the instantaneous center of the adjusting member is moved to compensate so that the gap between the main body and the door is constant, as shown in FIG. Thus, if the gap is allowed to change from δ1 to δ3, the adjustment member 11 can be configured to rotate around the fixed shaft 14. FIGS. 12A, 12B, and 12C correspond to FIGS. 8A, 8B, and 8C, and FIG. 12A shows a state where the cover amount is maximized (the door 3 is moved to the left end). 12 (b) shows a state where the cover amount is set to the middle, and FIG. 12 (c) shows a state where the cover amount is minimized (the state where the door 3 is moved to the right end). Indicates. The hatched lines in FIG. 12 indicate the hinge body 4, and the dots indicate the adjustment member 11. The adjustment member 11 is supported by the hinge body 4 so as to be rotatable only about the axis 14 which is a pivot. When the adjustment screw 13 is turned, the adjustment member 11 rotates only around the shaft 14. As the adjustment member 11 rotates around the shaft 14, the door 3 moves in the left-right direction. The rotation of the adjusting member 11 tends to change the gap between the main body 2 and the door 3. As shown in FIGS. 12 (a) to 12 (c), the gap increases from δ1 to δ3 as the door 3 moves from the left end position to the right end (as the covering amount decreases).
