Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a waterproof structure for a sliding skylight device mounted on a roof of a house.

[Prior Art] As a conventional skylight device, the one shown in FIGS. 7 and 8 has been proposed (see Japanese Utility Model Laid-Open No. 1-118525). That is, this skylight device is of a hinge type, and is composed of a pedestal 1 fixed to the roof R and having a rectangular shape, and a lid 2 pivotally supported at an end of the pedestal 1. The lid 2 is composed of a glass 3 and a sash 4 fitted to a peripheral portion of the glass 3, and a water blocking portion 9 bent downward is integrally formed at an end portion of the sash 4. .

On the other hand, the pedestal 1 has a double structure having an inner wall 5 and an outer wall 6. Inner weather strips 7 and outer weather strips 8 are attached to the upper ends of the inner wall 5 and the outer wall 6, respectively, and the weather strips 7 and 8 are in close contact with the sash 4 when the lid 2 is closed. As a result, a double seal structure is formed.

The lid 2 is driven and rotated by a driving device (not shown) arranged between the inner wall 5 and the outer wall 6 of the pedestal 1 to automatically open and close.

[Problems to be Solved by the Invention] However, in such a conventional skylight device, although the double seal structure is formed by the both weather strips 7 and 8, the respective weather strips 7 and 8 are The lower surface of the sash 4 is a close-contact seal that seals against the lower surface. Therefore, a negative pressure generated during a storm causes a force F in the direction of separating the lid 2 from the pedestal 1 to act, and when the lid 2 floats and displaces,
The pressure contact force of the weather strips 7 and 8 against the sash 4 is reduced.

At this time, since the water-impervious portion 9 is only slightly extended below the outer weather strip 8, raindrops are scattered in all directions by wind pressure, as in a storm. Raindrops easily enter the inside of the water shield 9. Therefore, after the raindrop W that has entered the inside of the water-impervious portion 9 enters between the inner wall 5 and the outer wall 6 from between the outer weather strip 8 and the sash 4 whose pressure contact force is reduced as described above, the inner weather is further There is a risk that it may enter between the strip 7 and the sash 4 and drip into the room.

The present invention has been made in view of such conventional problems, and an object of the present invention is to provide a waterproof structure of a slide-type skylight device with improved waterproof performance in a storm.

[Means for Solving the Problems] In order to solve the above problems, the present invention comprises a pedestal and a lid slidably supported by the pedestal, both of which are rectangular in shape. Slide along the side,
In a sliding skylight device that operates to open from the front side to the rear side, in the side and front sides, a groove having a substantially U-shaped cross section formed in either one of a pedestal and a lid, A mating seal is provided that comprises a weatherstrip disposed along the groove and a horizontal flange formed on the other side and received by the groove weatherstrip.

Further, the rear side portion is provided with a vertical surface seal portion that is attached to one of the stand or the lid and is in close contact with the other vertical surface, and the side edge portion and the rear side portion of the lid are A water shielding portion is provided to cover the outer side surface and the outer lower surface of the pedestal, and the front side portion is located outside the fitting seal portion and is disposed on either one of the pedestal and the lid and is in close contact with the other. A water seal is provided.

Further, it is preferable that a water shield plate that covers a gap between the front side of the pedestal and the front side of the lid is attached to the front side of the pedestal.

[Operation] In the above configuration, the pedestal and the lid are first waterproofed by the water blocking portion and second waterproofed by the fitting seal portion at the side portions. Further, in the rear side part, the first waterproof is made by the water blocking part,
In addition, the close sealing portion provides second waterproofing. Further, in the front side portion, the waterproof seal portion is first waterproof, and the fitting seal portion is second waterproof. Therefore, the rectangular pedestal and the lid have a double waterproof structure formed by the first waterproof and the second waterproof over the side portion, the rear portion, and the front portion, that is, the entire circumference. Becomes

The fitting seal portion is composed of a groove having a substantially U-shaped cross section, a weather strip arranged along the U-shaped groove, and a horizontal flange received in the weather strip. Therefore, the horizontal flange is in close contact with the weather strip on each of the upper and lower surfaces. Therefore, if a force that causes the lid to float from the pedestal is applied due to the negative pressure generated during a storm,
When the lid floats under this force, the horizontal flange and the weather strip are pressed against each other more strongly.

Therefore, when the negative pressure is generated in such a storm, the weather strip is pressed against the upper surface of the flange more strongly, so that the sealing performance is improved rather than the normal time. The sealability between the front part and the front part is secured.

On the other hand, in the rear side portion, unlike the side side portion and the front side portion, the front side fitting seal is not provided, but a close seal portion that is attached to either the pedestal or the lid and is in close contact with the other is provided. Has been. Therefore, even if the lid floats from the pedestal due to the force at the time of rainstorm, the close contact state can be maintained by the close contact seal portion.

For this reason, also in the rear side portion, the sealing performance in a storm is secured as in the case of the side portion and the front side portion. Therefore, the rectangular pedestal and lid cover the entire circumference thereof in a storm. Sealability is secured.

Further, not only is the water shield part provided on the front side part and the rear side part, but also by providing the water shield plate on the front side part,
Even if raindrops scatter from unspecified directions due to wind pressure during a storm, the raindrops are blocked by the water shield and the water shield over the entire circumference of the pedestal and lid.
