Description

[Detailed Description of the Invention] This invention relates to an upper hinge attachment device for attaching a rotating window to a window frame. The purpose is to provide a hinge mounting device for a rotating window that allows the hinge to be easily mounted without performing any mounting work on the window upper frame.

Conventionally, in order to attach a hinge of a rotating window or the like to an upper frame, screw holes are provided in the upper frame and the hinge is attached using the screw holes. Therefore, it is necessary to drill screw holes in the upper frame, which is very time-consuming. Furthermore, since the hinge is fixed to the upper frame, it cannot be removed if the hinge breaks down and you want to replace it. Even if you take it out, the mounting plate that fixes the hinge next time is inside the upper frame, as seen in Japanese Utility Model Application Publication No. 54-9549, so it is very difficult to fix the hinge. difficult or impossible.

This idea was made by focusing on the above-mentioned problems. This will be explained below with reference to the embodiments shown in the drawings.

1 and 2, a lip groove 2 opening downward is provided on the lower surface of a window upper frame 1 to which a rotating window is attached, and a concave groove 3 is provided at the bottom of the lip groove. The tips of the lips 4, 4 protruding from both sides of the opening of the lip groove 2 are bent into an L shape and stand up in the groove 2, and their edges form two horizontal locking strips 5, 5 facing each other. are doing.

A hinge shaft 6 that pivotally supports the rotating window is attached to a hinge plate 7 having a plate-like base plate by being engaged with the tip of a lever 10. The lever 10 is pivoted at a fulcrum 8, and the base end is attached to a screw 9.
is fixed to the head of Further, screw insertion holes 11, 1 with large play are provided at both ends of the hinge plate 7.
1 is perforated. The hinge plate 7 is disposed between the rising surfaces of the two lips 4, 4 of the upper frame 1 and along the lower surfaces of the locking strips 5, 5.

On the other hand, the mounting plate 12 to which the hinge plate 7 is attached is the third
As shown in the figure, it is a rectangular plate with a square notch in the center, and on both sides there are band-shaped guide pieces 13, 13 that protrude downward, and rectangular wing pieces 14 that protrude upward from both ends of the notch. 14 are formed.
Further, screw holes 15, 15 are bored at both ends. This mounting plate 12 is arranged in the lip groove 2 on the upper surface side of the locking strip strip 5, the wing pieces 14, 14 enter into the groove 3 of the upper frame, and the guide pieces 13, 13 are arranged in the lip 4, respectively. The tip of the rising edge is in contact with the upper surface of the lip 4 along the rear surface. Then, the hinge plate 7 and the mounting plate 12, which are vertically opposed to each other, are tightly connected by tightening the screws 16, 16 passing through the screw insertion hole 11 and the screw hole 15, and the hinge 7 is pressed against the lower surface of the locking band strip 5 and fixed. installed. In FIG. 1, reference numeral 17 designates the upper stile of the rotating window which is pivotally mounted by the hinge plate 7.

As shown in FIG. 3, this mounting plate 12 is provided with two notches at one side edge of a notch in the center, and a locking pawl 18 that is raised downward. Also the fourth
As shown in the figure, a notch 19 is provided at the edge of the locking band strip 5 corresponding to this locking pawl 18, and the mounting plate 12 is positioned by locking the locking pawl 18 in the notch 19. There is.

When attaching the hinge plate 7 to the mounting plate 12 by screwing the screw 16 inserted through the insertion hole 11 into the screw hole 15, the position of the hinge shaft 6 must be precisely and finely adjusted in the portion of the insertion hole 11 that has a large play. Tighten and secure.

This hinge mounting device has the above configuration, and when installing this mounting device, the hinge plate 7
and the mounting plate 12 are loosely temporarily fastened in advance with screws 16, and the hinge plate 7 is pushed in from the longitudinal end of the upper frame 1 along with the lower surface of the locking band strip 5, and moved to release the locking claw 18. is locked in the notch 19 for positioning, and the screw 16 is tightened to press and fix the hinge plate 7 to the lower surface of the locking band strip 5. At this time, the mounting position of the hinge plate 7 is finely adjusted depending on the play size of the insertion hole 11.
In addition, as shown in FIG. 5, only the mounting plate 12 is inserted into the lip groove 2 of the upper frame 1 in advance, and the hinge plate 7 is
from below to the locking strip strip 5, and at a predetermined position facing the mounting plate 12, attach the hinge plate 7 and the mounting plate 1.
It is also possible to fix the hinge 7 by tightening the screw 16 between the hinge 7 and the hinge 7. The method (2) is convenient when the window frame is not assembled, and the method (2) is convenient because the hinge can be installed without removing the frame, such as when the hinge plate 7 is damaged and needs to be replaced.

This invention is as described above, and the mounting device of this invention has a wing piece and a guide piece on the mounting plate, the guide piece is in the lip groove of the upper frame, and the wing piece is in the concave groove along the rear surface of the rising lip. Since the locking band strip is located at a predetermined width position on the top surface of the locking band strip in the longitudinal direction, the locking claw can be accurately placed in the notch of the locking band strip. Easy longitudinal positioning. Furthermore, since the hinge plate is finely adjusted through the insertion hole with a large amount of play, the hinge installation accuracy is extremely high. When screwing in screws, even if the tips of the screws hit the mounting plate, they do not lift up much, making it easy to align and tighten the screw holes. This results in the following effects. The hinge can be installed or replaced without creating screw holes in the upper frame. Can be installed accurately and easily using only screws.
