Abstract

PROBLEM TO BE SOLVED: To make homogeneous the quality of a hinge capable of adjusting the inclination of a sash frame erected on a window frame. SOLUTION: This hinge has a vertically extended cylindrical body 4 on a hinge piece 1 attached to the stile of a window frame, and a small-diameter shaft part 6 provided on the lower part of a fulcrum shaft 2 is inserted in the cylindrical body 4. Also, the end 3a of a threaded shaft 3 is inserted in a shaft insertion hole 8 radially drilled through the fulcrum shaft 2, and held so as to be capable of freely turning. In addition, the threaded shaft 3 is engaged with a threaded hole 13 formed on the stile of the sash frame, thereby adjusting the inclination of the sash frame on the rotation of the threaded shaft 3. In this case, a pin hole 9 for communication with the shaft insertion hole 8 is formed on the fulcrum shaft 2, so as to be orthogonal with the shaft insertion hole 8, and a pin is inserted in the pin hole 9. Furthermore, an engagement groove for engagement with the pin is formed on the external surface of the end 3a of the threaded shaft 3.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge capable of correcting the inclination of a shoji frame attached to a window frame.

[0002]

2. Description of the Related Art Generally, hinges of this type are known as shown in FIGS. This hinge is a hinge piece 22 having a cylindrical body 21 extending vertically.
And a fulcrum shaft 24 into which a small-diameter shaft portion 23 provided in the lower part of the cylindrical body 21 is inserted, and a shaft insertion hole 25 formed in the fulcrum shaft 24 and penetrating in a radial direction, and an end is rotated. And a screw shaft 26 freely supported. Screw shaft 2
6 has a square shaft portion 27 which engages with a rotary operation tool.
Is provided.

In this hinge, a hinge piece 22 is fixed to a vertical frame of a window frame A, and the screw shaft 26 is inserted into a screw hole formed in a vertical frame of a shoji frame B together with a shoji-side mounting plate 28 as shown in the figure. By screw-engaging, it is attached to each of the window frame A and the shoji frame B. When the turning operation tool is engaged with the square shaft portion 27 and the screw shaft 26 is turned, the shoji frame B moves in the longitudinal direction of the screw shaft 26 with respect to the window frame A, and The inclination of the shoji frame B with respect to the window frame A can be corrected while B is attached to the window frame A.

In this hinge, the end of the screw shaft is protruded to the opposite side of the shaft insertion hole so that the screw shaft does not come out of the shaft insertion hole of the fulcrum shaft. I'm trying to crimp. However, when the screw shaft is swaged in this way, when manufacturing the hinge,
Since it is difficult to keep the amount of caulking applied to the end of the screw shaft constant, rattling occurs in the mounting part between the screw shaft and the fulcrum shaft, leaving a point to be improved in obtaining a product of uniform quality. I was

It is an object of the present invention to obtain a hinge of uniform quality by attaching a screw shaft to a fulcrum shaft without caulking the end.

[0006]

In order to solve the above-mentioned problems, according to the present invention, in the above-mentioned hinge, a pin hole which is orthogonal to the shaft insertion hole and is communicated with the shaft insertion hole is formed in the fulcrum shaft. Then, a pin is inserted into the pin hole, and an engaging groove for engaging with the pin is provided on the outer periphery of the end of the screw shaft.

In such a hinge, the screw shaft attached to the shaft insertion hole of the fulcrum shaft is not disengaged from the fulcrum shaft by engagement of the pin inserted into the pin hole of the fulcrum shaft with the engagement groove at the end of the screw shaft. Like that. Therefore, when the screw shaft is mounted on the fulcrum shaft, it is not necessary to caulk the end of the screw shaft, and there is no play in the mounting portion between the screw shaft and the fulcrum shaft.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The hinge shown in FIGS.
The frame comprises a hinge piece 1 attached to the vertical frame of the window frame A, a fulcrum shaft 2 rotatably attached to the hinge piece 1, and a screw shaft 3 screwed to the vertical frame of the shoji frame B.

The hinge piece 1 has a cylindrical body 4 opened in the vertical direction in the lower half thereof, and tapered screw holes 5a formed in both the upper and lower ends and the center. .

The fulcrum shaft 2 has a small-diameter shaft 6 formed in the lower half thereof, and a ring 7 made of synthetic resin is fitted into the lower half small-diameter shaft 6. The fulcrum shaft 2 is dropped into the cylinder 4 of the hinge piece 1 from above, and the fulcrum shaft 2 and the cylinder 4
And the ring 7 is interposed therebetween to smoothly rotate. In the upper half of the fulcrum shaft 2, a shaft insertion hole 8 penetrating in the radial direction of the fulcrum shaft 2, and a pin hole 9 orthogonal to the inner upper surface of the shaft insertion hole 8 and communicating with the shaft insertion hole 8. Are formed respectively.

The screw shaft 3 has a screw thread 10 on the outer peripheral surface,
When the end 3a is fitted into the shaft insertion hole 8 of the fulcrum shaft 2,
It is formed to rotate smoothly. An engagement groove 11 extending in the circumferential direction is formed on the outer peripheral surface of the end 3a of the screw shaft 3.
This engaging groove 11 intersects with the pin hole 9 of the fulcrum shaft 2 when the screw shaft 3 is fitted into the shaft insertion hole 8 of the fulcrum shaft 2. At the end of the screw shaft 3, a square shaft portion 12 that engages with the tip of a spanner is provided.

As shown in FIG. 3, a pin P is inserted into the pin hole 9 of the fulcrum shaft 2 and the pin P is inserted into the engagement groove 11 of the screw shaft 3 inside the shaft insertion hole 8 as shown in FIG. And is attached to the shaft insertion hole 8 of the fulcrum shaft 2. The pin P is prevented from falling out of the pin hole 9 by crushing the head at the opening of the shaft insertion hole 8. Also,
The screw shaft 3 is screwed with a sash-side mounting plate 14 provided with a screw hole 13 at the center as shown in the figure. A pair of screw holes 5 b, 5 b similar to the hinge piece 1 are provided on the shoji-side mounting plate 14 with the screw hole 13 interposed therebetween.

In order to use this hinge, the hinge piece 1 is screwed to the vertical frame of the window frame A, while the hinge piece 1 is screwed to the vertical frame of the shoji frame B provided with the shaft hole 15 at a position connectable to the hinge piece 1. Screws are attached to the shoji-side mounting plate 14, and the screw shaft 3 is screwed into the screw hole 13 of the shoji-side mounting plate 14. Then, the small-diameter shaft portion 6 of the fulcrum shaft 2 is dropped together with the ring 7 into the cylindrical body 4 of the hinge piece 1, and as shown in FIG.
And are rotatably connected.

At this time, if the distance between the window frame A and the shoji frame B is not appropriate, or if the shoji frame B is inclined with respect to the window frame A, the spanner The head is engaged, the screw shaft 3 is rotated in one direction, and the sash frame B is moved in the length direction of the screw shaft 3 to correct the interval and the inclination.

In such a hinge, the screw shaft 3 attached to the shaft insertion hole 8 of the fulcrum shaft 2 has the pin P inserted into the pin hole 9 of the fulcrum shaft 2 and the engagement groove 11 of the screw shaft 3 end 3a. , So that it does not come off the fulcrum shaft 2,
When attaching the screw shaft 3 to the fulcrum shaft 2, it is not necessary to caulk the end 3a of the screw shaft 3. For this reason, rattling does not occur in the mounting portion between the screw shaft 3 and the fulcrum shaft 2, and a product of uniform quality can be obtained.

In this embodiment, the screw shaft 3 is mounted on the vertical frame of the shoji frame B via the shoji-side mounting plate 14, but the screw shaft 3 is directly screwed into the shaft hole 15 of the shoji frame B. It may be.

[0017]

As described above, in the hinge according to the present invention, the screw shaft can be mounted on the fulcrum shaft without caulking the end, so that the mounting portion between the screw shaft and the fulcrum shaft is rattled. And a product with stable quality can be obtained.
