Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a round window having a circular or arched shape when viewed from the front, and particularly to an inner window frame that is attached to an outer window frame so as to be openable and closable.

(Prior Art) Fig. 3 is a vertical cross-sectional view of a conventional round window having a circular shape when viewed from the front. Alternatively, the window inner frame, which is rotatably mounted around the horizontal axis, is formed by bending each straight member into a circle with the required curvature. Unlike the window frame A, which is fixed in a fixed position, an operating force is applied each time the window is opened or closed, so a strong, hollow rectangular cylindrical shape material as shown in the figure is used. In other words, the shape material used for this window inner frame B is a horizontal wall with a glass groove forming frame piece C protruding from one side, and indoor and outdoor side walls E and F protruding from both ends of the other side. The free end portions of these side walls E and F are connected to each other by a connecting wall G to form almost the entire hollow rectangular tube shape.

(Problem to be solved by the invention) Since the conventional window inner frame uses a hollow rectangular cylindrical shape material almost entirely, this hollow rectangular cylindrical shape material can be bent using the simplest roll bending machine. If you try to bend it using a bender, this hollow rectangular cylindrical shape material will become stiff and the product value will decrease, so you have no choice but to use a pipe bender, but with this pipe bender, In some cases, if the curvature of the material to be bent is changed, it is necessary to manufacture a bender mold corresponding to the curvature, which has the drawback of making the mold extremely expensive.

In view of the above-mentioned problems, the present invention aims to provide an inner frame for a round window that can be manufactured at low cost.

(Means for solving the problem) The window frame of the present invention to achieve the above purpose is as follows:
An indoor side wall 6 and an outdoor side wall 7 are vertically provided at both ends of the other side of the horizontal wall 5 having a glass groove forming frame piece 4 protruding from one side, and a reinforcing partition wall 8 is provided between the both side walls 6 and 7. are vertically installed, and these side walls 6, 7 and partition wall 8
A plurality of hollow parts 1 connected to each other by horizontal walls 9 and 10 parallel to the horizontal wall 5 and continuous in the indoor and outdoor directions.
1, 12, and 13 is formed by bending the molded material 2a with a required curvature so that the horizontal wall 5 is on the inner peripheral surface side.

(Example) To explain the example with reference to the drawings, Fig. 1 is a front view of a circular round window, and Fig. 2 is an enlarged vertical sectional view thereof. is the window frame 1 that is installed and fixed on the building frame side.
Then, it is inserted into this window outer frame 1, and the window outer frame 1
For example, the window frame 2 has a window inner frame 2 which is rotatable around horizontal axes 1a, 1a, which is interposed between the window frame 2 and the window frame 2, and a disk-shaped glass plate 3 is fitted into the window inner frame 2.

The window frame 2 has an indoor side wall 6 and an outdoor side wall 7 vertically disposed at both ends of the other side of a horizontal wall 5, which has a glass groove forming frame piece 4 vertically protruding from one end thereof. Reinforcing partition walls 8, 8 are provided between both side walls 6, 7.
Further, both reinforcing partition walls 8, 8 are connected by horizontal walls 9 parallel to the horizontal wall 5, and each of the indoor side and outdoor side walls 6, 7 and each reinforcing partition wall 8 are also connected parallel to the horizontal wall 5. a main shape member 2a made of an extruded aluminum shape material, each interconnected by a horizontal wall 10;
Using a roll bender, bend the glass presser molding material 2b, which is a hollow rectangular cylindrical extruded aluminum molding material with a small cross-sectional shape, into a circular shape with the required curvature, with the horizontal wall 5 facing the inner circumferential surface side. Main mold material 2 processed and bent into this circular shape
A circular glass holding member 2b is attached to a position facing the glass groove forming frame piece 4 at a position with screws (not shown). still,
The glass holding member 2b is attached after the glass plate 3 is fitted.

In the bending process of the main shape material 2a using the roll bender, the main shape material 2a is hollow, but the hollow portion is formed by the indoor and outdoor side walls 6, 7, which are vertically disposed at both ends of the horizontal wall 5. 3 with a small cross section by the reinforcing partition walls 8, 8 between these side walls 6, 7, and the horizontal walls 9, 10, 10 interconnecting these side walls 6, 7 and the reinforcing partition walls 8, 8.
The hollow parts 11, 12, 13 are divided into two hollow parts 11, 12, 13, and these hollow parts 11, 12, 13 extend in the axial direction of a roll bender (not shown) that is placed on the horizontal wall 5 (in other words, in the indoor and outdoor directions). In addition, since the cross section of the main frame member 2a is symmetrical except for the glass groove forming frame piece 4, the hollow parts 11, 12, 13 are connected to each other during bending.
The shape material is bent into a circular shape while maintaining the original cross-sectional shape of the shape material without being stiff or warping of the side walls 6, 7 or the reinforcing partition wall 8. Further, since the main mold member 2a is a hollow rectangular cylindrical body consisting of the three hollow portions 11, 12, and 13 as described above, it has sufficient strength.

A caulking material 14 is filled between the glass groove forming frame piece 4 of the main mold material 2a and the glass holding mold material 2b, and the reinforcing partition wall 8 and the indoor side and outdoor side walls 6, 7 of the main mold material 2a are filled with a caulking material 14. Each groove portion 15 formed with the horizontal wall 10 has an inner circumferential side surface 1 of the window outer frame 1.
A water fin 17 that can be brought into close contact with 6 is attached.

In the embodiment described above, the main frame member 2a has a horizontal wall 5.
Two reinforcing partition walls 8, 8 are formed between the indoor side wall 6 and the outdoor side wall 7, which extend vertically from both ends of the It would be good to have one article in place. Further, a horizontal wall 9 connecting the side walls 6, 7 and the reinforcing partition wall 8,
10 may be formed between the tips of the side walls 6, 7 and the reinforcing partition wall 8. In addition, in the embodiment, the frame pieces for forming glass grooves are provided only on one end side of the horizontal wall, and the glass holding molding material is attached to the other end side, but the frame pieces for forming glass grooves are provided on both ends with opposing protrusions. This is particularly suitable for arched round windows.

(Effect of the invention) Although the frame forming the window frame of the invention has a hollow rectangular cylindrical shape, the hollow part is connected to the indoor side and outdoor side walls hanging from both ends of the horizontal wall, and these side walls. It is divided into a plurality of hollow parts with relatively small cross sections by the reinforcing partition walls between them and the horizontal walls connecting these side walls and the reinforcing partition walls, and these hollow parts are connected in the indoor-outdoor direction. Furthermore, since the cross section of the mold material is almost symmetrical except for the frame piece for forming the glass groove, the hollow part will not be compressed even when bent using a roll bender. Since the horizontal walls, side walls, and reinforcing partition walls do not warp, the original shape of the profile can be maintained, and product value is not impaired. Furthermore, since a roll bender, which is the simplest type of bending machine, can be used, costs can be significantly reduced compared to conventional products using a pipe bender.
