Abstract

PROBLEM TO BE SOLVED: To prevent torsion of a wooden fitting by mounting a shaft on the bearing part of the base end of attaching pieces screwed on a fitting frame and the fitting respectively, making the base part side of the respective attaching pieces thicker than the edge side, and closing the loose end side of the fitting to the fitting frame in an abutting state at the time of using. SOLUTION: A flag hinge 1 attaching a fitting such as a single swinging door on a fitting frame is composed of attaching pieces 4, 4 arranged vertically, cylindrical bearing parts 5, 5 provided on the base parts of the attaching pieces 4, 4, and a shaft inserted in the bearing parts 5, 5. The attaching pieces 4, 4 form a screw insertion holes 9, 9... on the upper and lower parts of an edge side 7 and a base part side 8, and the base part side 8 is formed to be thicker than the size of the edge side 7. One attaching piece 4 is fixed on the fitting frame, and the other attaching piece 4 is fixed on the fitting. Thus, at the time of closing of the flag hinge 1, the loose end of the fitting 3 is closed on a door stop in an abutting state, and the fitting can be opened and closed along the substantially movable range of the fitting without any torsion.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flag hinge for preventing a fitting from being twisted.

[0002]

2. Description of the Related Art In a conventional flag hinge, a mounting piece for screwing to a fitting such as a fitting frame and a swing door is formed of a plate material having the same thickness at both the front end and the base end. If a hinge is used to attach a fixture such as a hinged door, most of the fixtures will be twisted, and the door will not open completely and will rebound slightly and open. Here, the reason why the fittings attached with the conventional flag hinges are twisted will be described. FIG. 5 is a view showing the one-sided door fitting 3 attached with the conventional flag hinge 1A. A gap 13 of 2-3 mm is formed between the door stop portion of the frame and the door fitting on the frame hanging side 12 in the figure. On the other hand, a gap of 2 to 3 mm is also formed in the portion on the hand side 14 of the frame, and the fitting is not completely closed unless the hand side of the fitting moves to this gap. In other words, a fitting such as a hinged door attached with a conventional flag hinge has a substantially movable range of 1
If you do not move to the depth beyond 5 (extra 2-3 mm), it will not close completely. The small gap created when attached with the conventional flag hinge 1A is a cause of poor closing of the fittings such as a hinged door, "torsion".

[0003]

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem that a fitting attached with a conventional flag hinge may not be properly closed or torn.

[0004]

The flag hinge of the present invention has mounting pieces which are screwed to a fitting frame and a fitting, respectively, and a shaft is mounted on a bearing portion at a base end of each of the mounting pieces. In the flag hinge, each of the mounting pieces is thicker on the base side than on the tip side, so that the free end of the fitting is closed in contact with the fitting frame when used.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a first embodiment of the present invention will be described. In the first embodiment of the present invention shown in FIGS. 1 to 3, reference numeral 1 denotes a fitting 3 such as a single door on a fitting frame 2.
The flag hinge 1 of the present invention is mounted on the fitting frame 2 and the fitting 3 so as to be screwed to the fitting frame 2 and the fitting 3, respectively. It comprises cylindrical bearings 5 and 5 provided on the bases 4 and 4 respectively, and a shaft 6 fitted into these bearings 5 and 5. The mounting pieces 4, 4
Are screw insertion holes 9 at the top and bottom of the tip side 7 and the base side 8,
9, 9, 9 are formed, and the base side 8 is formed to be 0.5 mm thicker in the present embodiment than the dimension of the front end side 7. When the flag hinge 1 having the above configuration is used, as shown in FIG.
Is fixed by using a screw (not shown) such as a countersunk screw, and the other mounting piece 4 is similarly fixed to the fitting 3 by using a screw (not shown). The fittings 3 attached in this way are the respective mounting pieces 4 of the flag hinge 1,
Since the base side 8, 4 of 4 is formed thicker, it exceeds the door stop of the fitting frame 2, and when closed, the free end of the fitting 3 closes in contact with the door stop, so that the fitting 3 is not twisted. It can be opened and closed smoothly along the substantially movable range 10 of the fitting.

Second Embodiment Next, as a second embodiment shown in FIG. 4, a mounting piece main body 4A in which the mounting piece 4A of the flag hinge 1A is formed to have the same thickness on both the tip side 7 and the base side 8 is provided. The flag hinge 1A constituted by a plate-like spacer 11 made of a lead material or the like adhered to the base side of the attachment piece main body 4A with a double-sided tape or the like, and the first embodiment described above can be used. It has the same function and effect as described above.

[0006]

As described above, if the flag hinge 1 of the present invention is used to attach a fitting such as a hinged door, as described above, anyone can open and close smoothly without any special skills or experience. It becomes possible to simplify the installation work of fittings.
