Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a double-opening sash used for example in dormer windows, and more specifically, a hanging hinge is installed in a locking groove of an upper frame provided in an opening. The locking piece is dropped in, and the support plate of the support hinge is fixed to the fixed piece of the lower frame with a fixing screw, and the indoor sash is made into a center-divided opening/closing door by the hanging hinge and the support hinge. Regarding the double door Satsushi.

<Prior Art> Openings in dormer windows, roof overhangs, and the like that protrude from the roof surface have a triangular or pentagonal shape with sloped sides at the top.

In addition, if the window glass sash is installed on the outdoor side of the opening in a double-door structure, it will be difficult to open and close the screen door or other sash placed on the indoor side with double doors on the outdoor side. A structure that opens and closes on the indoor side may be used.

In such a case, it is not easy to install a sash having a center-dividing hinge in a narrow space on the indoor side such as a dormer window or an overhang roof from the viewpoint of construction and maintenance.

FIG. 5 shows a hanging hinge 8 constituting the hinge part 4.
FIG.

FIG. 6 is a front view of the supporting hinge 9 in the hinge portion 5 at the center C2 of the lower frame, and FIG. 7 is a plan view thereof.

The support hinge 9 consists of a support plate 91 fixed to the lower frame 21 and two mounting plates 93, 93 pivotally attached to the indoor end (support side) of the support plate 91 via a pin 92. It is configured.

The support plate 91 has an end piece 94 hanging down at one end, and a branch piece 95 hanging down at the other end.

The mounting plates 93, 93 extend one end to form pivot pieces 96, 96, and the pivot pieces 96, 96 and the support plate 91 are configured to be pivotable by a pin 92, and the mounting plates 93, 93 are fixed to the bottom of the lower frames 31, 31 by suitable means such as screws.

On the other hand, the support plate 91 is fastened to the fixed side 25 formed on the lower frame 21 with a fixing screw 97 screwed into one end thereof. The fixing screw 97 has a knurled finish on the outer periphery of the head so that it can be easily fixed and removed manually.

In this case, the end pieces 94 and support pieces 95 provided at both ends of the support plate 91 are configured to sufficiently support the load of the screen door 3.

The installation work of the suspension hinge 8 and support hinge 9 constructed as described above will be explained in more detail.

First, the mounting plates 84, 84 of the hanging hinge 8 are fixed in advance to the upper sides of the upper frames 34, 34 of the screen door 3, respectively.

On the other hand, mounting plates 93, 93 of the support hinge 9 are also fixed to the bottom sides of the lower frames 31, 31 of the screen door 3.

Furthermore, as described above, the mounting plates 84, 84 and the mounting plates 93, 93 are provided with the hanging plate 81 and the support plate 91 via the pins 82 and 92, respectively.

In this state, first, the locking pieces 83, 83 of the hanging plate 81 are dropped into the locking grooves 24, 24 of the upper frame 23 from above. Then, the hanging hinge 8 is temporarily engaged with the upper frame 23.

Next, with the end piece 94 provided on the support plate 91 of the support hinge 9 in contact with the fixing piece 25, the fixing screw 97 is screwed into the screw hole and fastened to the lower frame 21.

That is, the suspension hinge 8 and the support hinge 9 form a drop-in engagement structure, and the sash is attached to the upper and lower frames by engagement and fixation of the upper and lower frames of both hinges.

In this way, by first attaching the hanging hinge 8 to the upper frame 23 and then screwing the supporting hinge 9 to the lower frame 21, it is possible to easily open the room in the opening where the lower frame 21 and the upper frame 23 are provided in advance. The screen doors 3, 3 can be attached from the inside narrow space.

Furthermore, when removing the screen doors 3, 3 once installed, first loosen the fixing screw 97 of the support hinge 9 by manually rotating the knurled head, and remove the support plate from the fixing piece 25 of the lower frame 21. Open 91. When the screen doors 3, 3 are lifted upward, the locking pieces 83, 83 of the hanging hinge 8 are removed from the locking grooves 24, 24.

Therefore, the screen doors 3, 3 as a whole can be easily removed from the opening frame.

<Effects of the invention> As described above, in the double door sash according to the invention, the upper hanging hinge is attached to the upper frame, and then the support hinge is screwed to the lower frame, so that the sash such as a screen door can be used as a dormer window, etc. It can be easily removed from the opening frame by installing it in the opening on the indoor side of the room or vice versa.

Furthermore, it can be easily installed and removed in narrow indoor spaces such as dormer windows, and since the hanging hinge is completely fixed within the upper frame, it can sufficiently support the load of the screen door. At the same time, the end pieces and support pieces of the support hinge can easily bear the load of the screen door, so the workability as a whole is extremely high, and it has stability and durability.
