Description

[Detailed description of the invention] Industrial application field The invention is based on a metal window frame attached to a wooden frame attached to an opening in the roof, and a window plate attached to this window frame so that it can be opened and closed by raising and lowering or swinging. The present invention relates to a device for preventing dew condensation on the groove forming piece itself that constitutes the dew receiving groove of a window frame in a skylight.

Problems to be solved by conventional techniques and ideas In this type of skylight, if the window board is closed when the outside temperature is low, a temperature difference will occur between the outside and inside of the window frame, and the inside surface of the window frame will be closed. To prevent this, moisture in the air condenses and drips indoors or seeps into the wooden frame, causing it to rot. , the tip of the groove constituting the dew-receiving groove protrudes inward and further rises upward, and the bottom part of the groove-receiving groove is fixed to a wooden frame to catch the water droplets. Measures are taken to store it in a groove and, in some cases, to discharge it to the outside through a discharge hole installed in the exposed groove, but as the window frame is cooled by outside air, it is formed integrally with it. The groove component pieces that have been removed are also cooled in the same way, and as a result, moisture in the air condenses on the groove component itself, and although the amount of condensation is not as large as that on the window frame, it also forms water droplets and falls down. It was hot.

Means for Solving the Problems As a means for solving the above problems, the skylight condensation prevention device of the present invention provides a method for preventing condensation along the inside of the lower end of a metal window frame between the window frame and the window frame. The tip of the groove constituting the exposed groove protrudes inward and rises upward, and the bottom part of the groove constituting piece is fixed to a wooden frame attached to the opening in the roof, and the window frame In a skylight in which a window plate is attached to the upper surface so as to be openable and closable, on the outer surface extending from the bottom to the rising part of the groove component,
It has a structure in which a synthetic resin material having elasticity is stretched.

Functions and Effects According to the above-mentioned configuration, the present invention has a synthetic resin material having elasticity stretched on the outer surface of the rising part of the groove component piece constituting the exposed groove, which functions as a heat insulating material and Even when the piece is cooled, dew condensation can be prevented from forming on the outer surface of the rising part.Moreover, the bottom of the groove component is also covered with an elastic synthetic resin material, so that the bottom of the groove component can be prevented from condensing. When fixed to a wooden frame, the synthetic resin material is elastically inserted between the two, ensuring a secure seal between the groove component and the wooden frame, and improving rain protection. There is.

Embodiment Hereinafter, an embodiment of the present invention will be described based on FIG.

In the figure, reference numeral 1 denotes an aluminum window frame having a rectangular plane. Along the inside of the lower end of the window frame 1, there is a groove forming piece 3 whose tip protrudes inward and further rises upward. This groove component piece 3 is curved.
A drain groove 2 is formed between the window frame 1 and the drain groove 2. A drain hole 4 is transparently provided at the outer corner of the drain groove 2, and a drain hole 4 is provided in the lower surface of the drain groove 2. A synthetic resin material 6 having elasticity made of urethane foam resin is bonded to one side of a substrate 5 made of ABS resin bent twice at right angles, so as to extend along the outer surface of the groove component piece 3 from the bottom to the rising part. The part of the synthetic resin material 6 that was applied to the bottom of the groove component piece 3 is placed on the top surface of the wooden frame 7 attached to the opening of the roof, and the hole 3a is transparently provided at the bottom of the groove component piece 3.
The screws 8 passed through the holes 5a of the substrate 5 and the holes 6a of the synthetic resin material 6 are inserted into the wooden frame 7 while elastically contracting the synthetic resin material 6.
The groove component piece 3 is fixed to the wooden frame 7 by screwing it into the frame 7.

A window plate 10 is attached to the upper surface of the window frame 1 so as to be openable and closable. A synthetic resin material 16 made of urethane foam resin is adhered to one side of the substrate 15 made of ABS resin similar to the above and whose peripheral edge is placed against the inner surface of the frame 11, and a sealing material fitted to the glass presser 17. 18, and the glass presser 17 is fixed to the lower surface of the frame 11 with screws 22, so that it is stretched.

The present embodiment has the above-described structure, and all water droplets that have condensed on the inner surface of the window frame 1 are received by the dew catch groove 2 and discharged to the outside from the drain hole 4, forming the dew catch groove 2. Since the synthetic resin material 6 having elasticity is applied to the outer surface of the rising part of the groove component piece 3, this acts as a heat insulating material and even if the groove component piece 3 and the window frame 1 are cooled together, , dew condensation is prevented from forming on the outer surface of the rising portion, and an elastic synthetic resin material 6 is also applied to the outer surface of the bottom of the groove component piece 3, and the groove component piece 3 is fixed to the wooden frame 7. At times, the synthetic resin material 6 is inserted between the bottom of the groove component 3 and the wooden frame 7 in an elastically compressed state, and the gap between the groove component 3 and the wooden frame 7 is reliably sealed.
