Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pivot hinge bearing whose position with respect to a horizontal frame can be adjusted.

[0002]

[Problems to be Solved by Prior Art and Invention]

 The pivot hinge and its bearing are combined by dropping the shaft of the pivot hinge into the bearing part of the bearing when the shoji is installed in the opening frame of the shoji. If the bearing is fixed to the horizontal frame with an error with respect to the shaft, it will affect the installation of the shoji.Therefore, it is necessary to adjust the position of the bearing with respect to the horizontal frame to match the shaft. is there.

Japanese Patent Laid-Open No. 5-149051 proposes a bearing in which two cylinders having different diameters with eccentric centers of inner circles are in contact with each other, but the position of the receiving portion While it has the advantage that the adjustment can be performed in a wide area on a plane, the adjustment work tends to be complicated because it is positioned using two parts, and the inner cylinder also serves as the shaft receiving part, so it is always necessary. The contact of the shaft may cause a deviation with respect to the outer cylinder.

The present invention has been made in view of the above background, and is intended to propose a bearing whose position can be adjusted with a simple structure.

[0005]

[Means for Solving the Problems]

 In the present invention, a spacer, which can be fitted into the mounting hole formed in the horizontal frame, is circumscribed around the rear side of the receiving part, and the center of the insertion hole of the spacer through which the receiving part is inserted lies on the plane of the spacer itself. The bearing is adjusted with a single component by making it eccentric to the center.

Since the center of the insertion hole of the spacer is eccentric from the center of the entire plane, the spacer changes its orientation while fitting into the mounting hole, thereby changing the position of the center of the insertion hole with respect to the center of the mounting hole. , The position of the receiving part with respect to the mounting hole can be adjusted simply by rotating it while being in contact with the receiving part.

【Example】

 The present invention will be described below with reference to the drawings showing an embodiment.

As shown in FIG. 1, the bearing 1 according to the present invention has a main body 10 having a cylindrical receiving portion 11 into which a shaft 31 of a pivot hinge 3 is inserted, and a rear surface of the receiving portion 11 which is circumscribed to make a sliding door. It is composed of a spacer 2 which can be fitted into a mounting hole 411 formed in a horizontal frame 4 which supports the horizontal frame 5, and the position of the receiving portion 11 with respect to the horizontal frame 4 is adjusted by the spacer 2.

As shown in FIGS. 1 and 2, the main body 10 of the bearing 1 has a plate shape overlapping the prospective piece 41 of the lateral frame 4 on the side for housing the shoji 5, and the surface on the shoji 5 side is formed into a horizontal plane. , The surface of the prospective piece 41 side inclines corresponding to the inclination. The receiving portion 11 projects from the rear side of the main body 10 toward the lateral frame 4, and the insertion hole 111 into which the shaft 31 of the pivot hinge 3 is inserted is continuous from the surface on the shoji 5 side in a bag shape. In the embodiment, a neck portion 12 having a relatively small diameter is formed on the outer periphery of the receiving portion 11 on the rear surface side of the main body 10 and the spacer 2 is circumscribed. Prevents it from slipping out and integrates the two.

The spacer 2 has a shape that can be fitted into a mounting hole 411 formed in the prospective piece 41, and an insertion hole 21 through which the receiving portion 11 of the main body 10 is inserted is formed in the center. In the case of the embodiment, the insertion hole 21 is formed so as to have a size circumscribing the neck portion 12 of the receiving portion 11.

As shown in FIGS. 3 to 5, the center of the insertion hole 21 of the spacer 2 through which the receiving portion 11 is inserted is eccentric with respect to the center P of the mounting hole 411 on the plane. In the embodiment, the center of the insertion hole 21 is located on the center line in the prospective direction passing through the center of the spacer 2 itself, and is eccentric with respect to the center line of the lateral frame 4 in the longitudinal direction, and at the same time, the spacer 2 is attached. When the horizontal frame 4 is fitted to the 411 while restraining the movement of the horizontal frame 4 in the longitudinal direction, the center of the insertion hole 21 is on the center line P in the prospective direction of the mounting hole 411, as compared to the direction of FIG. 4, As shown in FIG. 5, by changing the direction of the spacer 2, the position in the eccentric direction is adjusted by the eccentric distance e of the insertion hole 21 from the center of the spacer 2.

After the position adjustment by the spacer 2, the main body 10 is fixed to the horizontal frame 4 by screws screwed into the prospective piece 41. After adjusting the position of the main body 10, the screw can be screwed into the prospective piece 41 by opening the screw hole 101 of the main body 10 in the shape of a long hole in the position adjusting direction (the length direction of the horizontal frame 4). To do.

The shaft 31 of the pivot hinge 3 is inserted into the receiving portion 11 from the body 10 side of the bearing 1 as shown in FIG. It rotates while contacting the washer 6 arranged at. FIG. 1 shows the shoji 5 in an open state.

Since the receiving portion 11 of the bearing 1 has a bag shape, when the shoji 5 is installed in the bathroom and the horizontal frame 4 is the lower frame, the drain hole 112 is opened in the receiving portion 11 and the insertion hole 111 is formed. Water that has penetrated inside is eliminated. The water discharged from the drain hole 112 into the horizontal frame 4 is discharged to the bathroom from the drain hole 421 opened in the bathroom-side finding piece 42.

[Effect of device]

 The present invention is as described above, and a spacer that can fit into the mounting hole formed in the lateral frame is circumscribed around the rear side of the receiving part, and the center of the insertion hole of the spacer through which the receiving part is inserted is placed. Since the spacer is eccentric with respect to the center of the plane, it is possible to adjust the position of the bearing with respect to the horizontal frame by changing the direction of the spacer.
