(Problem to be solved by the invention) However, the above-mentioned composite sash has a problem that it is inevitably expensive and difficult to spread. One of the reasons for this is that when the object to be fitted into the inner sash frame is a door, a shoji, a double door, a single door, etc., there are various types of doors, so depending on the object to be fitted, There was a situation where I had to create and prepare an inner satsushi frame.

The present invention has been made for the purpose of providing an internally attached composite sash that solves the above-mentioned problems.

(Means for Solving the Problems) In other words, the internal composite sash of the present invention is a composite sash that is made by connecting a main sash that fits into an opening in a house wall with an inner sash that protrudes indoors from the wall of the house. The main sash is provided with a connecting part composed of a vertical piece and a horizontal piece on the indoor side thereof, and the frame materials of the upper and lower frames and the left and right vertical frames forming the inner sash are made of the same material. The main body is formed of a hollow body having a rectangular cross section, and a hollow connecting piece protruding in the inner circumferential direction is formed on the outdoor side of the main body, and a position closer to indoors on the inner surface side of the frame of the main body is formed. A protrusion is formed on the connecting piece, and a fitting groove for storing tight material is formed on the indoor side of the connecting piece, and the inner sash is connected to the connecting part of the main sash from the outer circumferential side through the connecting piece. The gist is that they are connected by inserting screws in the circumferential direction.

(Function) According to the above configuration, the door can be fitted into the inner sash frame by cutting out a portion of the protrusion, and a shoji can also be fitted by attaching an auxiliary member to the groove. The fitted door may be a double door or a single door.

(Example) Hereinafter, the present invention will be explained based on embodiment figures.

Figure 1 shows a main sash A fitted into an opening 1 in the wall of a house, an inner sash B on the indoor side and an outer sash C on the outdoor side, and a decorative board 2 attached to the indoor side of the house wall. A cross-sectional view of the state is shown.

Regarding the combination of main sash A and outer sash C,
It has almost the same structure as before, and the main sash A

7 has a leg part 8 standing on the inner circumferential surface of the opening 1, and a connecting part 9 for coupling with the inner sash B is provided at the indoor end of each frame 4, 5, 6, and 7. The connecting portion 9 is composed of a vertical piece 10 and a horizontal piece 11, and has left and right vertical frames 4,
5 and the lower frame 7, a hanging strip 12 is formed on each vertical piece 10 toward the indoor side.

The inner sash B has a frame-like structure with left and right vertical frames 13, 14 and upper and lower frames 15, 16 corresponding to each member of the main sash A, and the members of the main sash A and outer sash C have different cross-sectional shapes. In contrast to the extruded aluminum profile, each member of the inner sash B is an extruded profile made of synthetic resin and has the same cross-sectional shape.

Each frame member constituting the inner sash B is made of an extruded shape as described above, and its cross-sectional shape generally consists of the main body 17, which is the main part, and the connecting piece 18 to the main sash A. The main body 17 is formed into a hollow body having a rectangular cross section with a wide width, and a concave curved portion 19 is provided at the indoor end of the main body 17. A protrusion 20 is formed,
The protrusions 20 and the concave portions 19 form a stepped shape suitable for the appearance of the frame. Furthermore, bis pockets 21, 21 are provided at both ends of the hollow space. This bis pocket 21 is different from a general one and is completely hollow.

The connecting piece 18 is formed in a hollow rectangular cross-sectional shape with a narrow width, is connected to the main body 17 at a corner in the cross section, protrudes from the main body 17 in the same direction as the protrusion 20, and has the main body 17 on the inner circumferential side of the frame. A shallow groove 22 is formed by the protrusion 20 and the connecting piece 18 . However, the cross-sectional shape of the connecting piece 18 is not a perfect rectangle, and a fitting groove 24 for the tight material 23 is provided on the indoor side facing the main body 17, a groove 25 is provided on the opposite side, and a groove 25 is provided on the outside of the frame. A screw drop groove 26 is provided on the side surface.

For the inner sash B, the ends of each frame member formed in the same cross-sectional shape are cut diagonally at an angle of 45 degrees, and screws 31 penetrating through the upper and lower frames 15 and 16 are inserted into the bis pockets 21 of the vertical frames 13 and 14. It can be assembled in the same way as a picture frame by screwing it in.

The inner sash B is attached to the hooking strip 12 formed on the connecting portion 9 of the main sash A member.
The concave groove 25 of the connecting piece 18 of the member is engaged, and the screw 26a passed through the horizontal piece 11 of the connecting part 9 is screwed into the drop groove 26 of the connecting piece 18 to connect it to the main sash A.

In addition, when installing the door 27, the notch 20 of the protrusion 20 is formed in the left and right vertical frames 13, 14 of the inner sash B, and the piece 30 of the hinge 28 is hung on the notch 29.
It is fixed to the main body 17 with screws 53, and both vertical frames 13,
A door 27 is attached to each of 14.

In the above embodiment, the door 27 is installed so that it can open on both sides, but it is also possible to install the door on one side by using the same mounting structure of the hinge 28. Shallow groove 22
Since there is a shallow groove 22, a folding door can be attached by using the shallow groove 22 as a groove rail. Furthermore, since the cube can be stably fixed by hanging in the shallow groove 22, it is also convenient for attaching a plate glass to one side.

FIG. 5 shows the second embodiment, in which the upper frame 1
By attaching an auxiliary member 32 to the door 5, the groove is made deep, and the installation is stabilized by the deep groove 33 so that the folding door 52 does not come off.

The auxiliary member 32 has a hanging piece 35 protruding from the base piece 34 so that the protrusion 20 extends, a groove 36 that connects with the protrusion 20 is provided at a location that corresponds to the protrusion 20, and the base piece 3
4 is fixed to the main body 17 of the upper frame 15 with screws 37.

(Effects of the invention) Since the present invention is constructed as described above, the inner sash is connected to the connecting part of the main sash through the connecting piece of the inner sash, and the inner sash can be made of a section having the same shape. Therefore, versatility is provided, and as a result, mass demand can be realized, and the cost of the internal composite sash can be reduced as a whole. Furthermore, the protrusions on the inner sash can be used as a positioning part when attaching another member, if necessary, and usually contribute to the appearance.On the other hand, the fitting groove can store a tight material,
This also makes it possible to keep the inner door airtight. Furthermore, in the present invention, the inner sash is connected to the connecting part of the main sash through a connecting piece by inserting a screw from the outer circumferential side to the inner circumferential direction, and the connecting piece has a hollow shape. Therefore, the tips of the screws do not protrude indoors due to the presence of the hollow part, and the heads of the screws are located outdoors, so that the screws, especially the screw heads, are not visible from indoors. It looks better. In this regard, when screws are inserted from the inner circumferential side as in the past, flat screws (those with flat heads) are used from the viewpoint of appearance, making it difficult to select screws with round heads etc. In addition, even in a screw structure, if a screw is inserted from the side where the hollow part is located (from the inner circumferential side), there will be an inconvenience that the connection state cannot be grasped because the hollow part is in between. The invention can avoid such drawbacks.
