Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a window frame having a flat rounded shape or a front rounded shape.

(Prior Art) In a rounded window frame shown in FIG. 3 (a), upper and lower horizontal frame members 1a and 1b of a window frame body 1 and a light-transmitting panel 2 such as a window glass are supported from both inside and outside the room. The upper and lower lateral members 3a and 3b of the panel retainers 3 and 3 are bent, but when the window frame body 1 and the panel retainers 3 and 3 are integrally formed,
Since the cross-sectional structure is complicated, the upper and lower horizontal frame members 1a and 1b of the window frame body 1 or the upper and lower horizontal members 3a and 3b of the panel retainers 3 and 3 are deformed to reduce the commercial value when subjected to the R-bending process. , May be unusable. Further, as shown in FIG. 3 (b), the same problem occurs in the front view rounded window frame in which the window frame body 1 and the upper portions of the panel retainers 3 and 3 are bent.

Therefore, conventionally, in this type of rounded window frame, as shown in FIG. 4, the window frame body 1 and the panel retainers 3 and 3 are separately formed, and the panel retainers 3 and 3 are attached to the inner circumference of the window frame body 1. The surface is fixed with screws 4 and the caulking material 6 is filled in the recessed line portion 5 formed on the outer edge of the outdoor side panel retainer 3 to form a gap between the outdoor side panel retainer 3 and the window frame body 1. The α is blocked to prevent rainwater from entering the room through the gap α.

(Problems to be Solved by the Invention) In the above-described conventional rounded window frame, even if the caulking material 6 is used, a gap α between the outdoor side panel retainer 3 and the window frame body 1 is formed.
Even if is made watertight, the panel presser 3 has a screw through hole 7,
Moreover, since the screw holes 8 for screwing are respectively provided in the window frame body 1, rainwater may enter the indoor side through the through holes 7 and the screw holes 8.

The present invention has been made in view of the above conventional problems, and an object thereof is to provide a rounded window frame in which rainwater does not enter the indoor side.

(Means for Solving the Problem) In order to achieve the above-mentioned object, the present invention provides a flat rounded shape or a front rounded shape in which a translucent panel 2 such as a window glass is fitted to a window frame body 1 by a panel retainer 3. In the window frame of
A packing fitting groove 10 is formed in the panel retainer 3, and a packing 11 having a cross-sectional area larger than the cross-sectional area of the groove 10 is fitted in the packing fitting groove 10.
Employs a configuration in which it is fixed to the window frame body by a screw 4 that is screwed through the packing 11 fitted in the packing fitting groove 10.

(Embodiment) FIG. 1 shows an essential part of an R-shaped window frame which is an embodiment of the present invention. The window frame body 1 has an outdoor frame member 12 and an indoor frame member having a U-shaped cross section. 13 is bent into a round shape, and is formed into a hollow shape by fastening both with screws 14, and one of the panel retainers 3 and 3 that supports the transparent panel 2 such as window glass from both inside and outside the room The outer panel retainer 3 is provided with a reinforcing hollow portion 15 and a packing fitting groove 10 that opens downwardly below the hollow portion 15, and a packing 11 is provided in the fitting groove 10 as shown in FIG. 2 (a). It is fitted. The packing 11 has a cross-sectional area slightly larger than the cross-sectional area of the packing fitting groove 10, and its rear surface 11a
Is formed in a convex shape, and its front surface 11b is formed in a concave shape, and further front surface protruding portions 11c and 11d slightly protrude below the packing fitting groove 10, and the protruding portion 11c,
When 11d is pushed into the packing fitting groove 10, the packing 11 is deformed into a substantially rectangular shape along the cross-sectional shape of the packing fitting groove 10.

Therefore, as shown in FIG. 2 (b), the outdoor side panel retainer 3 is passed through the outdoor side panel retainer 3 and the packing 11, and the screw 4 is screwed into the screw hole 8 of the window frame main body 1 so that the outdoor side panel retainer 3 is closed. When it is fastened to the body 1, the front protrusion 11 of the packing 11
c and 11d are pressed into the packing fitting groove 10 in a compressed state, and the compression reaction force causes the packing 11 to move to the inner peripheral surface of the packing fitting groove 10 as shown by an arrow in FIG. 2 (b).
It comes into close contact with the window frame body 1 and the screw 4. For this reason, the gap α between the outdoor side panel retainer 3 and the window frame body 1 and rainwater that tries to enter the interior side from between the screw 4 and the screw hole 8 are both blocked by the packing 11, and the conventional The filling of the waterproof caulking material, which is required in the window frame assembly method, can be omitted.

(Effect of the Invention) According to the present invention, it is possible to reliably prevent water from entering the room through the screw holes for screwing the panel retainer to the window frame body, which was impossible with the conventional filling of caulking material. it can.

Moreover, since the conventional troublesome caulking material filling work is not required, the construction is easy.

Furthermore, since the cross-sectional structure of the panel retainer is almost the same as the conventional one, it does not hinder the bending process peculiar to the round window frame.
