Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a curved frame material used to construct the frame of a Western-style casement window or doorway that has a rounded transom at the top. It is.

(Prior art) In general, window frames, doorway frames, etc. made of light metals such as aluminum are mostly constructed by cutting straight shapes obtained by extrusion molding into appropriate lengths. However, in order to form an inverted U-shaped window frame, for example, the straight section is partially curved to form a curved section and a straight section, and the curved section is In addition to providing transoms on the sides, the structure includes opening and closing windows on the straight sections.

By the way, in the above-mentioned profile, since the part to which the sealing material is attached inside the frame and the protruding piece forming the door stop are integrally formed during extrusion molding, wrinkles may occur in the protruding piece in the rounded part. This has the drawback of deteriorating the appearance and impairing the sealing performance against air and water between the frame and the door or the fitted glass.

Therefore, the U-shaped frame forming the base of the frame and the auxiliary frame provided with the protruding piece are formed separately, and at this time, the auxiliary frame is divided into a curved portion and a straight portion. However, a frame having a protruding piece on the inside was formed by individually attaching each of the frame members corresponding to each part along the inside of the frame after being curved. Since the auxiliary frame was joined to the auxiliary frame by joining metal to metal, there was a problem in that it was inferior in waterproofness and airtightness.

(Purpose of the invention) This invention was made by focusing on the above-mentioned conventional problems. Through the protruding piece, it is possible to install sealing material, fix the fitted window, and even fit the door against the shoji.It improves waterproofness and airtightness, has a good appearance, and reduces assembly man-hours. The purpose of the present invention is to provide a curved frame material that can be reduced in size.

(Structure of the invention) The structure of the curved frame material according to this invention is to bend a profile integrally provided with a protruding piece in the longitudinal direction with the protruding piece inside, and to separate the straight part and the rounded part. In addition to forming a member having a curved radius, a separate auxiliary member curved in a radius corresponding to the curvature of the curved radius portion is attached to the inner circumferential surface of the curved radius portion to hide the protruding piece. .

(Example) This invention will be explained below based on the drawings.

As shown in FIGS. 2 and 3, one of the protruding pieces 8 has a fitting groove 8a over its entire length for fitting the tight material 17, and both protruding pieces 8 have a fitting groove 8a over its entire length. 8 and 21 are cut off at the boundary between the curved portion 2a and the straight portion 2b in order to attach the intermediate frame 4 to the frame body 2.

The intermediate frame 4 has a glass holding piece 4b having a "shaped" cross section protruding from the center of the upper surface of the hollow part 4c, and a rim member 13 on the indoor side thereof.
In addition, a downwardly protruding portion 4a is formed on the lower surface side of the hollow portion 4c to coincide with the position of the protruding piece 8. A groove portion 4e for attaching a tight member 17 is provided on the outdoor surface of the protruding portion 4a, with which the upper edge of the indoor side of the door 6 comes into pressure contact when the door 6 is closed.

Incidentally, a synthetic resin fin 15 for draining water is fitted onto the lower surface of the intermediate frame 4 on the outdoor side, and projects downward on the outdoor side of the closed door.

The intermediate frame 4 is connected to the inverted U-shaped frame 2 at a portion where the protruding pieces 8, 21 are removed, and the fitting groove 8a of the straight portion 2b of the frame 2 is connected to the frame 2.
The groove portion 4e of the intermediate frame 4 is brought into communication.

On the other hand, the lower frame 3 is also formed with a horizontal protrusion 3a that substantially coincides with the position of the protrusion piece 8, and the lower edge of the indoor side of the door 6 is pressed against the outdoor surface of the horizontal protrusion 3a when closed. A groove 16 for attaching the tight material 17 is provided, and as a result of the groove 16 communicating with the fitting groove 8a of the straight portion 2b of the frame 2, each groove 16, 4e and the fitting groove 8a , the tight material 17 that is in close contact with the periphery of the indoor side of the doors 6, 6 is installed on the same plane in an endless state.

Further, the curved portion 2a on the upper side of the frame 2
Separate auxiliary frame 10 (auxiliary member) attached to
is obtained by bending a section having a length corresponding to the inner circumferential dimension of the radiused portion 2a in accordance with the curvature of the radiused portion 2a;
A curved portion 2 is provided at both indoor and outdoor ends of the base wall 10b, which faces the glass fitting groove 10a and has a glass fitting groove 10a in the central portion.
The auxiliary frame 10 is provided with leg walls 10c and 10d that come into contact with the inner circumferential wall of a, but the auxiliary frame 10 is shaped in advance so that it does not have protruding pieces on the inner circumferential surface side that may cause wrinkles during radius bending. Extruded.

The auxiliary frame 10 is screwed to the curved portion 2a with the protruding pieces 8, 21 fitted between the fitting groove 10a and the leg wall 10d on the outdoor side. Then, a semicircular fitting part is formed between the curved part 2a and the intermediate frame 4, and the glass 5 is attached to this part.

(Effects of the invention) As explained above, according to the rounded bending frame material of this invention, a section integrally provided with a projecting piece in the longitudinal direction is partially rounded with the projecting piece inside. a member having a straight portion and a curved portion, and a separate auxiliary frame is provided on the inner circumferential surface of the curved portion, which is curved in advance in accordance with the curvature of the curved portion. The auxiliary frame conceals the wrinkles that occur in the protruding piece when the extruded profile is integrally molded in the longitudinal direction and the profile is rounded with the protruding piece inside. Therefore, it has the advantage that wrinkles on the protruding pieces do not appear on the surface and do not impair the appearance.Furthermore, since the protruding pieces on the straight parts are integrally formed, it is possible to avoid wrinkles. The protruding piece on the straight part and the protruding piece on the curved part were attached as an auxiliary frame separate from the frame, and there was a metal-to-metal joint over the entire inner circumference of the inverted U-shaped frame. Waterproofness and airtightness in straight sections are significantly improved compared to conventional frames. Furthermore, it is possible to delete the protruding piece that is covered by the auxiliary frame at the curved part.
Rather, if the protruding piece is actively utilized rather than being deleted, not only will the work of positioning the auxiliary frame be easier, but the work of cutting out the protruding piece will become unnecessary, and the protruding piece and the auxiliary frame will be mutually connected. Waterproofness due to the complex internal morphology in the polymerized state.
The airtightness can be further improved, and the frame body can be manufactured easily, so that the number of assembly steps can be reduced.
