Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a hinge. More specifically, it relates to hinges used for windows and doors.

INDUSTRIAL APPLICABILITY The hinge of the present invention can be applied to any type of window, such as a side opening, an upper opening, a lower opening, etc., as long as the window or door rotates about the hinge. The windows and the like used include, for example, smoke exhaust windows and windows provided inside and outside of the crossing and other buildings, as well as windows provided in vehicles and various other industrial fields.

[Prior Art] FIG. 7 shows an upwardly opening window as an example of a conventionally known window.

(1) is a window, which has an upper shaft (2), a lower shaft (3) and a vertical shaft (4).
The upper shell (2) of the window (1) is attached to the upper shell (7) of the window frame (6) by the hinge (5), and the window (1) is an arrow (A) to the window frame (6). Rotate in the direction. (10) is a switch, which includes an outer cylinder (11) and an insertion member (1
2) and has a function of opening and holding the window (1) at an arbitrary angle.

The hinge (5) is known, and as shown in FIG.
It is composed of a single mounting plate (51) and a shaft pin (53) passed through the knuckle portion (52) of each mounting plate (51). Then, each mounting plate (51) is provided with a screw insertion hole (54), and the hinge (5) has this hole (54).
It is designed to be attached to the window frame (6) and window casing (2) through screws.

[Problems to be Solved by the Invention] In a conventional window, the knuckle portion (52) of the hinge (5) can be seen from the outside, which is not good looking. Especially,
If you open the doors of a house upside down, the hinges will be too conspicuous, and their decorative value will be lost.

In addition, to attach various windows to houses etc.
Installing hinges on site is complicated.

SUMMARY OF THE INVENTION In view of such circumstances, an object of the present invention is to provide a hinge in which a mechanism portion cannot be seen from the outside and a window can be easily attached by simply inserting it in the field.

[Means for Solving the Problems] The hinge of the present invention is (a) a first mounting plate made of a thin plate, a shaft metal fitting made of a support shaft protruding from the first mounting plate, and (b) a flat plate shape made of the thin plate. And a second mounting plate formed on the second mounting plate so as to be rotatable between the engaging position and the restraining position on the second mounting plate and overlapping with the second mounting plate, and attached to the tip end portion thereof. The lever comprises a flat plate-shaped thin plate having a recess into which the support shaft fits, and a bracket having a fixing means for fixing the lever in a restraining position. The fixing means is provided with a screw and a lever. Screw holes,
It is composed of a female screw hole provided in the second mounting plate.

[Operation] In the hinge of the present invention, since there is no member protruding to the outside unlike the knuckle portion of the conventional hinge, the mechanism portion cannot be seen from the outside and the appearance is improved.

In addition, since the second mounting plate and lever of the receiving bracket are made of flat thin plates, the entire receiving bracket is made very thin, and it is completely stored in the narrow gap between the window and the window frame to open and close the window. There is no problem.

Further, since the fixing means is composed of the screw, the screw hole provided in the lever, and the female screw hole provided in the second mounting plate, the number of parts of the receiving fitting can be reduced.

In addition, by fitting the shaft fitting fixed to the window or the window frame into the recessed part of the lever tip of the window frame or the receiving fitting fixed to the window and fixing the lever in the restraining position, the window and the window frame can be rotatably mounted by itself. Therefore, the installation work at the construction site is easy.

[Embodiment] Next, the present invention will be described based on an embodiment applied to an upper opening window.

FIG. 1 is a perspective view showing a shaft fitting (20) and a receiving fitting (30), FIG. 2 is a perspective view showing the receiving fitting (30), FIG. 3 is a front view of the receiving fitting (30), and FIG. FIG. 6 is a side view of the receiving metal fitting (30), FIG. 5 is an explanatory view of a hinged state, and FIG. 6 is a sectional view taken along line (I)-(I) in FIG.

An upper opening window is shown in FIGS. A shaft bracket (20) is attached to the upper shell (2) of the window (1), and the vertical frame of the window frame (6) is attached.
A bracket (30) is attached to (8). Although only one side of the window (1) and the window frame (6) is shown in this figure, of course, the shaft metal fitting (20) and the bracket (30) should be attached to both sides of the window (1) and the window frame (6). It is what is done.

The shaft fitting (20) includes an L-shaped first mounting plate (21) and a first mounting plate (2).
It consists of a pin-shaped support shaft (22) implanted in 1).
Then, the shaft metal fitting (20) is a screw (23) with the upper shaft (2) and the vertical shaft of the window (1).
It is fixed at the intersection of (4). The first attachment plate (21) may be a simple flat plate and may be attached in the middle of the vertical shaft (4) of the window (1).

As shown in FIGS. 3 to 4, the receiving metal fitting (30) is rotatably attached to the rectangular second mounting plate (31) and the second mounting plate (31) by the pin (32). Has a lever (33). Second
The mounting plate (31) and the lever (33) are formed of flat thin plates as shown in FIG. The mounting plate (31) is provided with a long hole (34) for passing a mounting screw. further,
A rectangular block-shaped closing member (35) is provided at the upper end of the second mounting plate (31).
Is fixed, and a U-shaped notch (36) is formed in the lower portion thereof. At the tip of the lever (33), a shaft metal fitting (2
A recess (37) into which the support shaft (22) of (0) is fitted is formed, and a screw hole (38) is formed at the lower end.

In FIG. 3, the position indicated by the solid line of the lever (33) is the engagement position, and when it is in this position, it receives the support shaft (22) of the shaft fitting (20) fixed to the window (1). be able to. The position indicated by the chain line of the lever (33) is the restraining position, and in this state, the opening of the recess (37) of the lever (33) is closed by the closing member (35).

A female screw hole (39) is formed on the second mounting plate (31) at a portion corresponding to the screw hole (38) in the restrained position of the lever (33). As shown in FIG. 5, when the lever (33) is in the restrained position and the screw (40) is screwed into the screw hole (38) and the female screw (39), the lever (33) is fixed in the restrained position. It The screw (4
0), the screw hole (38) and the female screw hole (39) constitute a fixing means.

In the hinge of the present invention, for example, in the case of prefabricated construction, the shaft fitting (20) and the receiving fitting (30) are preliminarily attached to the window (1) and the window frame (6) at the factory.

At the construction site, as shown in Fig. 1, the lever (3
Shaft fitting fixed to the window (1) with 3) in the engagement position
Move (20) diagonally from above as shown by arrow (B), and
Fit the (22) into the recess (37) of the lever (33). Then, after the lever (33) is rotated to the restrained position and the lever (33) is screwed, the mounting is completed. The state is shown in FIG. As shown in FIG. 5, the lever
Since the support shaft (22) put in the recess (37) of (33) is pressed by the closing member (35) and there is no place to escape, it never disengages from the bracket (30).

As described above, when the window (1) is attached to the window frame (6),
As shown in FIG. 6, the hinge bracket (30) is also attached to the shaft bracket (2
0) It is completely invisible from the outside. Therefore, the appearance of the window is improved.

Although one embodiment of the present invention has been described above, the shaft fitting (20) may be attached to the window frame (6) and the shaft fitting (30) may be attached to the window (1). Furthermore, an appropriate position can be selected and attached to a door, a transom or other kind of window.

[Effect of the Invention] According to the present invention, the hinge is invisible from the outside, so that it has a good appearance and is easily installed on site.
