Description

[Detailed Description of the Invention] This invention relates to a multi-purpose hinge that allows the opening/closing direction and pivot position of a window to be arbitrarily selected.

The first purpose of this invention is to make it possible to install the shoji frame without drilling holes or cutting holes in the window frame or shoji frame, thereby shortening the construction period and achieving highly waterproof installation. The objective is to provide a hinge that

A second object of this invention is to provide a hinge that has excellent fixing strength to the window frame and the shapes that make up the shoji frame, and that allows the shoji frame to be firmly attached to the window frame.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

As shown in the figure, the hinge 1 is composed of two hinge plates 2 and 3, a shaft 4 that pivotally connects both plates 2 and 3, and fixing plates 5 and 5 that are screwed to each hinge plate. It has been.

In the illustrated case, the hinge 1 is an example used for a pull-down smoke exhaust window, and this window is composed of a window frame 6 and a shoji frame 7.

The material forming the vertical frame 8 of the window frame 6 is as shown in FIG.
Projections 9 and 10 are provided on both sides of the inner circumferential surface, the tips of which are bent at right angles toward the other side, and a groove 11 is formed between both projections 9 and 10.
is taking shape.

In addition, as shown in FIG. 2, the shape material forming the lower crosspiece 12 of the shoji frame 7 is provided with protrusions 13 and 14 on both sides of its lower surface, the tips of which are bent at right angles toward the other side. Articles 13, 14
A groove 15 is formed between them.

One of the hinge plates 2 described above is for fixing to the window outer frame 6, and as shown in FIGS. 1 and 3, the protrusion 9 of the vertical frame 8
, 10, and a vertical plate 21 that overlaps the outer surface between
It consists of a horizontal plate 22 bent at right angles from the lower edge and overlapping the frame 16 of the window frame 6, and a hanging wall 23 bent downward from the front edge of the horizontal plate 22. It is bent into a cylindrical shape, and the shaft 4 is fixed horizontally at this portion.

The perpendicular plate 21 has an engaging part 24 which is formed by bending the cut portions made on the top and bottom of the rear edge outward and fitting the protrusion 9 with the remaining part of the vertical plate 21, and a screw 25 through which the screw 25 is inserted. A plurality of through holes 26 are provided.

The other hinge plate 3 mentioned above is fixed to the lower crosspiece 12 of the shoji frame 7, and as shown in FIGS. ,
It consists of a hanging wall 28 bent downward at right angles from the front edge of the horizontal plate 27, and a cylindrical part 29 formed by bending the lower end of the hanging wall 28 is fitted onto the shaft 4, and one hinge plate 2
It can be freely rotated about the shaft 4.

The horizontal plate 27 has a protrusion 13 formed by bending the notches on both sides of the rear edge upward, and connecting the remaining portion of the horizontal plate with the protrusion 13.
A hooking portion 30 that fits externally into the housing and a plurality of through holes 32 through which screws 31 are inserted are provided.

The fixing plates 5 and 5 have a rectangular shape that fits within the groove 11 or 15, and are provided with a claw 33 and a plurality of tapped holes 34 at one longitudinal corner.

In the illustrated case, the hinge 1 is shown for the left side when viewed from the outside of the window, but in the case of the right side hinge plate 2 and 3, the arrangement of the hinge plates 2 and 3 on both sides is reversed from what is shown in the figure.

The hinge of this invention has the structure as described above, and the attachment of the shoji frame to the window frame will now be explained.

The installation work is carried out by fixing one hinge plate 2 to the window outer frame 6 and fixing the other hinge plate 3 inserted into the shaft 4 to the shoji frame 7.

First, the hinge plate 2 is fixed by inserting the fixing plate 5 into the groove 11, fitting the engaging part 24 into the protrusion 9, and fixing the plate 2 so that its horizontal plate 22 overlaps the lower frame 16. The screws 25 inserted into the respective through holes 26 are screwed into the screw holes 34 of the fixing plate 5.

The fixing plate 5 is positioned so that the protrusion 10 is sandwiched between the claw 33 and the plate 2, and the screw 25 is driven in in this state.

By screwing in the screws 25, the fixing plate 5 is pulled toward the hinge plate 2, and as shown in FIG. The hinge plate 2 is fixed to the window frame 6.

Next, the other hinge plate 3 has its cylindrical portion 29
is inserted into the shaft 4, the horizontal plate 27 is applied to the lower surface of the lower crosspiece 12, and the engaging part 30 is fitted to the protrusion 13.

If the fixing plate 5 is inserted into the groove 15 and the screw 31 inserted into the through hole 32 is screwed into the screw hole 34 of the fixing plate 5 and tightened, the fixing plate 5 will form a protrusion at the claw 33. 14 into an inclined shape, and the hinge plate 3 is fixed to the shoji frame 7 by fitting the engaging portion 30 to the protrusion 13.

Through the above procedure, the shoji frame 7 attached to the window frame 6 with the hinge 1 can be opened and closed about the shaft 4 as shown in FIG.

In addition, although we have shown an example of how hinge 1 is used to open outward with the bottom at the center, it is of course possible to use it to open horizontally by placing it vertically, or to open inward or outward centering at the top. It is possible.

As described above, according to this invention, two hinge plates connected by a shaft are each provided with a hooking part that fits externally on the protrusion of the profile by bending the gap between the cuts, and the hinge plate is fixed to the hinge plate with screws. Since the other protrusion is held between the fixing plate and the hinge plate, there is no need to make mounting holes or notches in the window frame or shoji frame when installing the hinge, making the installation process extremely easy. Not only does it make you look better, but it also improves the waterproof and windproof effects.

In addition, since the fitting is done by the protrusions on the engaging part and the protrusions are inserted between the fixing plates, strong fixing strength can be obtained, and if the fixing plate is provided with claws, it will be even more effective. This has the effect of preventing rattling from occurring.
