Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a horizontal frame of a window frame having a rounded shape (arc shape) in a plan view.

(Prior art and its problems) A flat rounded window frame is composed of a flat rounded upper and lower horizontal frame and a direct left and right vertical frame, which are usually made of extruded aluminum material. It is formed by bending a sheet-shaped mold material with a required curvature.

For example, as a lower horizontal frame, an aluminum extruded mold material as shown in FIG. 3 (A), that is, an indoor vertical part (a), an outdoor vertical part (b), upper and lower horizontal parts (c), (d) and When a mold made of an intermediate horizontal piece (e) is used and bent by a roll bender into a flat rounded shape with the outdoor side being the convex side, the indoor vertical piece (a) acts in its longitudinal direction. The compressive stress causes vertical expansion, and the outdoor vertical piece (b) tries to contract vertically due to the tensile stress acting in the longitudinal direction, so that the vertical horizontal pieces (c) and (d) As shown in FIG. 3 (B), an inward depression (f) is generated by the vertical extension that occurs on the indoor vertical part (a). Therefore, in the case of the lower horizontal frame, the lower horizontal part (d) side faces the window opening end face of the building and cannot be seen from the outside, so there is no problem even if the lower horizontal part (c) is dented (f). Although there is no dent (f) on the upper horizontal part (c), this dent (f) can be seen from the outside and the appearance is very bad, resulting in a significant decrease in product value. Become.

The present invention aims to solve such problems.

(Means for Solving the Problem) A horizontal frame of the present invention that can achieve the above object is a rectangular cylindrical mold member composed of an indoor vertical part, an outdoor vertical part, and an upper and lower horizontal part. A reinforcing thick portion is integrally formed on the outer surface of the indoor end of at least one of the horizontal portions over the entire length, and a step portion between the outer surface of the horizontal portion and the reinforcing thick portion is formed into a concave curved surface. The mold material formed in the above is bent in a plane R shape so that the outdoor side thereof is the convex side.

(Embodiment) An embodiment will be described with reference to the drawings. FIG. 1 is a vertical cross-sectional view of a flat R-shaped flush sash, and FIG. 2 is a plan view thereof. Here, the flush sash means a sash that is mounted so as to be flush with the window glass in the vicinity of the outdoor side surface of the sash (window frame).

This flush sash is composed of a flat R-shaped main window frame 1, a flat R-shaped glass mounting frame 2 connected to the flat R-shaped main window frame 1, and a flat R-shaped window glass 4 mounted on the frame 2 via packings 3, 3. And the upper and lower flat R-shaped glass pressing edges 5 and 5 for pressing and fixing the glass from the outdoor side. The main window frame 1 is formed by upper and lower horizontal frames 6 and 7 and left and right vertical frames 8 and 8 which are made of extruded aluminum material, and the glass mounting frame 4 is composed of upper and lower horizontal frames 9 and 10 which are made of extruded aluminum material. Left and right vertical frames in window frame 1
It is formed by part of 8,8.

The upper and lower horizontal frames 6 and 7 of the main window frame 1 are related to the present invention, and the upper horizontal frame 6 includes the indoor side vertical portion piece 11, the outdoor side vertical portion piece 12, the upper horizontal portion piece 13, and the lower horizontal portion piece 14. And a rectangular tubular aluminum extruded material consisting of the intermediate horizontal part piece 15, the reinforcing thick part 16 is integrally formed over the entire length on the outer surface of the inner end of the lower horizontal part piece 14, and the lower horizontal part piece 14 is formed. And the reinforcing wall portion 16 and the step portion 17 formed in a concave curved surface is formed by bending a flat bend with a roll bender so that the outdoor side is the convex side. is there. In addition, this aluminum extruded mold material includes the inner surface of the indoor vertical part 11 and the horizontal part 13, 14, 15
Grooves 18 each having a semicircular cross section are provided along the entire length at the intersections with the inner surface, and also at the intersections between the inner surface of the outdoor-side vertical piece 12 and the inner surfaces of the horizontal pieces 13, 14, 15 as well. A groove 19 is provided over the entire length, and a U-shaped frame piece 20 is provided on the outer surface of the lower end of the outdoor-side vertical portion piece 12.

Similarly for the lower horizontal frame 7, the indoor vertical part 21 and the outdoor vertical part 21
A rectangular tubular aluminum extruded material composed of 22, an upper horizontal part piece 23, a lower horizontal part piece 24, and an intermediate horizontal part piece 25.
A reinforcing thick portion 26 is integrally formed on the outer surface of the indoor side end portion of 23 over the entire length and a step portion between the upper horizontal portion piece 23 and the reinforcing thick portion 26.
It is formed by bending a mold material formed by forming 27 into a concave curved surface into a planar rounded shape, and this aluminum extruded mold material also includes the inner surface of the indoor side vertical part piece 21 and the horizontal part piece 23. Grooves 28 each having a semicircular cross-section are formed at the intersections with the inner surfaces of the inner surfaces 24, 25, and the same groove is formed at the intersections between the inner surfaces of the outdoor vertical piece 22 and the inner surfaces of the horizontal pieces 23, 24, 25. 29 are provided over the entire length, and a U-shaped frame piece 30 is provided on the outer surface of the lower end portion of the outdoor side vertical portion piece 22.

In the bending process of the aluminum extruded shape material for the upper horizontal frame 6 by the roll bender described above, the indoor side vertical piece 11 stretches in the vertical direction by the compressive stress acting in the longitudinal direction, and the outdoor side vertical piece 12 moves in the longitudinal direction. The tensile stress that acts tends to cause vertical contraction, and the upper horizontal piece 13
Is dented in the upper surface due to the upward extension of the indoor side vertical part piece 11, but the downward extension of the indoor side vertical part piece 11 is suppressed by the reinforcing thick part 16 for the lower horizontal part piece 14. Therefore, the recess formed on the lower surface of the lower horizontal portion piece 14 is much smaller than the recess on the upper horizontal portion piece 13 side, and in this case, the step portion 17 between the lower horizontal portion piece 14 and the reinforcing thick portion 16 is formed. If it is a flat surface such as a vertical surface, a boundary line is formed between the lower surface of the lower horizontal portion piece 14 that causes a slight dent and the vertical surface of the stepped portion, etc., and the appearance is impaired. There is a risk that cracks may occur due to the formation of different boundaries, but the step
Since 17 has a concave curved surface, such a boundary line is not formed. Also, the indoor vertical part 11 and the outdoor vertical part
12 has a semicircular groove 18, 18 at the intersection with the horizontal pieces 13 to 15.
9 is provided, the vertical stress acting on the indoor-side vertical portion piece 11 and the outdoor-side vertical portion piece 12 causes the groove 1
It is escaped and reduced by 8,19, and therefore, the degree of the recess formed in the upper and lower horizontal portion pieces 13,14 is further reduced as compared with the case where these groove lines 18,19 are not provided.

In the bending process of the aluminum extruded mold material for the lower horizontal frame 7, the upper and lower horizontal part pieces 23 and 24 have the opposite relationship to the case of the mold material for the upper horizontal frame 6, and the operation is exactly the same. twenty four
Is dented on the lower surface due to the downward extension of the indoor side vertical portion piece 21 in particular, but for the upper horizontal portion piece 23, the upward extension of the indoor side vertical portion piece 21 is suppressed by the reinforcing thick portion 26,
The upper surface of the upper horizontal portion 23 is slightly recessed. The functions of the grooves 28 and 29 are the same as in the case of the upper horizontal frame 6.

As described above, the upper horizontal frame 6 is provided with the reinforcing thick portion 16 only on the lower horizontal portion piece 14 side, and the lower horizontal frame 7 is provided with the reinforcing thick portion 26 only on the upper horizontal portion piece 23 side. The upper horizontal part 13 of the upper horizontal frame 6 and the lower horizontal part 24 of the lower horizontal frame 7 have a recess on the upper surface of the upper horizontal part 13 and the lower horizontal part 24 of the lower horizontal frame 7. Since it cannot be seen from the outside by touching the end face, there is no problem in appearance. Of course, it is possible to form reinforcing thick portions on the upper and lower horizontal portion pieces 13, 23, 14, 24 of the upper and lower horizontal frames 6, 7, respectively.

The upper and lower horizontal frames 9 and 10 of the glass mounting frame 2, the upper and lower glass holding edges 5 and 5, and the upper and lower indoor side glass supporting members 31 and 31 are formed by bending an aluminum extruded shape member into a flat rounded shape by a roll bender. Formed.

As is clear with reference to FIG. 1, on the upper surface of the upper horizontal portion 23 of the lower horizontal frame 7 which constitutes the main window frame 1, the reinforcement thick portion 26 at the indoor end and the U-shaped frame are formed. A dew condensation water receiving groove 32 is formed between the piece 30 and the dew condensation water which has condensed on the inner surface of the window glass 4 and flows down, and the dew condensation water accumulated therein is the U-shaped frame piece. The water is drained from the water draining hole 33 connected to the lower glass support member 31 to the lower horizontal frame 10 side of the glass mounting frame 2, and further through the water draining hole 35 provided in the glass support base 34,
It is adapted to be discharged to the outside of the room through the drainage hole 36 of the lower glass pressing edge 5.

In the above-described embodiment, the upper and lower horizontal frames 6, 7 constituting the main window frame 1 are aluminum extruded mold members, and the upper and lower horizontal part pieces 13, 13 and 1 are
Although the intermediate horizontal part pieces 15 and 25 are formed between 4 and 24, a mold material in which such an intermediate horizontal part piece 25 is not formed may be used.

(Operation and effect of the invention) The horizontal frame of the flat rounded window frame according to the present invention is integrally formed with a reinforcing thick portion on the outer surface of the indoor end of at least one of the upper and lower horizontal pieces on the indoor side. Since the molded material is bent in a plane R shape so that the outdoor side is on the convex side, the indoor vertical part acts in its longitudinal direction when the molded material is bent. The compressive stress causes vertical expansion, and the outdoor vertical piece tends to contract in the vertical direction due to compressive stress acting in the longitudinal direction. Elongation that occurs in the vertical piece is suppressed by this reinforcing thick part,
This minimizes the indentation on the outer surface of the horizontal piece. Further, since the step portion between the outer surface of the horizontal piece and the reinforcing thick portion is formed in a concave curved surface shape, a boundary is formed between the slight indentation on the outer surface of the horizontal piece and the reinforcing thick portion. Both of them are flush with each other without forming a line, which not only improves the appearance but also prevents the occurrence of cracks that are likely to occur on such a boundary line.

Therefore, according to the horizontal frame of the present invention, the appearance shape is not impaired and the commercial value is not reduced.
