Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a window having a round shape in a plan view, in particular, a window frame composed of left and right rigid frames and upper and lower horizontal frames having a round shape in a plan view. A round window glass having a plan view shape is fitted and fixed through a glass holding peripheral frame on the indoor side and the outdoor side, which is composed of a vertical member and upper and lower horizontal members having a round shape in a plan view. Indoor side and outdoor side with or without an intermediate side member having a substantially U-shaped cross-section, which is composed of a horizontal wall portion and a vertical wall portion, and an intermediate side member having a substantially I-shaped cross-section between the both members. The present invention relates to a device for discharging dew condensation water generated on a side surface of a room in a flat rounded window formed by joining openings of a mold member in a state of being inwardly facing each other.

(Prior Art) In manufacturing a window frame of a flat arel window as described above,
It is the simplest bending machine to use a combination of U-shaped cross-section and I-shaped cross-sections instead of using a single hollow square tubular shape as the profile for a flat rounded horizontal frame. In the case of bending with a different roll bender, if it is a single hollow square tubular shaped material with a large cross-sectional shape, the material cannot be bent and the original cross-sectional shape (square shape) cannot be maintained. This is because, in the case of a die-shaped die material or even a die material having an I-shaped cross section, the forming roll can be applied so as to match the internal shape of the die material, and proper bending can be performed.

FIG. 4 shows a lower horizontal frame A portion of a conventional flat arel window. The lower horizontal frame A includes an indoor side material a1 and an outdoor side material a2 each having a substantially U-shaped cross section and having a planar radius shape. They are formed so as to face each other and have their opposite ends engaged with each other and joined by screws B. C and D are glass holding peripheral frames arranged on the inner side and the outer side of the window glass E with the window glass E interposed therebetween, and are fixed with screws F and G, respectively, and H is a glass receiving pedestal. In order to discharge the dew condensation water generated on the indoor side surface of the window having such a lower horizontal frame A, a drainage hole I is conventionally provided in the upper wall portion of the indoor side material a1 and the outdoor side material a2 is used. The drainage port J is provided on the lower end side of the hanging wall part of the above, and the drainage hole I and the drainage port J are connected by a drainage hose or pipe K. Therefore, from the indoor side surface of the window glass E to the indoor side glass pressing peripheral frame. Condensation water accumulated along the C and flowing down to the upper surface side of the indoor-side mold material a1 is drained from the drain hole I and is discharged to the outside from the drain port J via the drain hose K.

(Problems to be Solved by the Invention) In the conventional dew condensation water discharging device as described above, the dew condensation water flowing down from the indoor side surface of the window glass E to the upper surface of the indoor glass holding peripheral frame C is further laterally below the window frame. When flowing down to the upper surface of the frame A, there was a problem that the dew condensation water did not flow into the drain hole I as it was but flowed into the room as it was or scattered into the room. Further, in this conventional device, it is difficult to attach the drain hose K, and the hose K
Must be installed after the indoor side mold material a1 and the outdoor side mold material a2 are joined to form the hollow rectangular tubular lower horizontal frame A, so even if it can be installed near the end of the lower horizontal frame A, The installation is almost impossible in the department. Also, when the dew condensation water on the upper surface side of the indoor side mold a1 enters the lower horizontal frame A through the minute gap between the joints of both molds a1 and a2 or the minute gap between the screw B and G holes in the joint. The condensed water accumulates on the bottom of the lower horizontal frame A, and in particular, as shown in FIG. 4, the screw pocket P provided at the center of the bottom surface of the indoor side mold a1 and the tip projection of the mold a1. The water accumulated in the recessed portion Q formed between the mold and the part cannot be discharged anywhere, and causes corrosion of the mold material.

In the embodiment shown in FIG. 1 and FIG. 2, the lower horizontal frame is made up of three mold members, that is, the U-shaped mold members on the indoor and outdoor sides and the I-shaped mold member interposed between these U-shaped mold members. Although,
FIG. 3 shows a U-shaped member 50 on the indoor side and a U-shaped member on the outdoor side.
The lower horizontal frame 3'consisting of two mold members 51 and 51 is illustrated.
According to this embodiment, the lower horizontal member 36 'of the indoor side glass pressing peripheral frame 6'is provided with the water drainage hole 41 and the drainage ridge 42 in the upper wall portion 36a and the drainage hole 44a in the lower wall portion 36b. Is provided,
Further, a drain hole 44b is provided in the upper horizontal wall 13 of the indoor-side mold member 50 at a position corresponding to the drain hole 44a. Then, the dew condensation water flowing down from the indoor side surface of the window glass 5 and accumulating on the upper surface of the upper horizontal frame 36 'is drained from the drain hole 41, and the space 45 inside the upper horizontal frame 36' and the drain hole 44a, 44b through a water drainage passage, and is flowed down onto the water drooping piece 27 of the water drooping frame 29 made of the T-shaped material provided inside the lower horizontal frame 3 ', and thereafter, it is the same as the case of FIG. is there. This water drop frame 29
The mounting frame piece 28 is screwed to the indoor side member 50. The same members as those in the embodiment of FIG. 1 are designated by the same reference numerals.

In these embodiments, as the waterproof ridge, the screw pocket used to connect the lower horizontal frame and the vertical frame with the screw is adopted, but the waterproof ridge can be specially formed.

(Operation and Effect of the Invention) According to the dew condensation water discharging device of the present invention, the dew condensation water generated on the indoor side surface of the window glass 5 and flowing down to the upper surface of the lower horizontal frame 36 of the indoor glass pressing peripheral frame 6 is The draining ridges 42 provided at the indoor side end of the upper surface of the lower horizontal frame 36 prevent the lower horizontal member 36 from overflowing or scattering into the room. The dew condensation water drained from the water drainage hole 41 of the lower horizontal member 36 is received on the water drooping piece 27 of the water drooping frame 29 through the water drainage passage, and passes through the minute gap between the joint ends of the mold members. Condensed water that has flowed down is also received on the water dripping piece 27. Then, these dew condensation water flows down from the water drop piece 27 to the bottom of the outdoor mold member 11, but the waterproof projection 22 provided there overflows the waterproof projection 22 to the inside of the room to join them. From the gap between the parts, the lower horizontal frame 3
