For example, a packing is provided on the window frame so as to correspond to the peripheral portion of the window glass in the closed position, and the window glass is sandwiched with the packing sandwiched between the window frame by a manual or electric pressing mechanism. .

[0004]

However, in the above-mentioned skylight, since a mechanical holding mechanism is adopted as a means for ensuring the airtightness and waterproofness between the window frame and the window glass, the structure is However, there is a problem that the weight becomes complicated and the manufacturing cost increases. Further, since a large load is applied to the peripheral portion of the window glass by the pressing mechanism, the strength of the window glass alone is insufficient, and a reinforcing frame must be provided on the peripheral portion of the window glass. In this case, a caulking process for ensuring airtightness must be further performed between the peripheral edge of the glass and the frame. Therefore, there is a problem that the structure of the skylight becomes more complicated.

The present invention has been made in view of the above circumstances. The airtightness and waterproofness between the window frame and the window glass can be ensured with a simple structure, and the weight and manufacturing cost can be reduced. The purpose is to provide a skylight.

[0006]

In order to achieve the above object, a skylight according to claim 1 is a window frame attached to a roof of a building, a window glass which is openably and closably attached to the window frame, and the closing thereof. A hollow expansion / contraction packing which is provided on the window frame corresponding to the peripheral edge of the window glass at the position, expands / contracts by adjusting air pressure, and seals the peripheral edge of the window glass in an expanded state in an airtight manner. Is characterized by.

A skylight according to a second aspect is the skylight according to the first aspect, characterized in that the expansion / contraction packing is made of a rubber tube.

A skylight according to a third aspect is the skylight according to the first aspect, characterized in that the window frame is provided with a fixed packing at a position facing the expansion / contraction packing with the window glass interposed therebetween.

A skylight according to a fourth aspect is the skylight according to the first aspect, characterized in that the window glass is provided so as to slide and open along an opening plane of the window frame.

[0010]

According to the skylight of claim 1, the window frame is attached to the roof of the building so that the window glass can be opened and closed, and air pressure is applied to the window frame corresponding to the peripheral portion of the window glass in the closed position. A hollow expansion / contraction packing that expands and contracts by adjustment and seals the peripheral edge of the window glass in an expanded state is provided, so that the airtightness and waterproofness between the window frame and the window glass are simple. It becomes possible to secure the weight, and it is possible to reduce the weight and the manufacturing cost. In this case, the airtightness between the window frame and the window glass can be released by contracting the expansion / contraction packing by adjusting the air pressure, and the window glass can be easily opened and closed.

Further, since the expansion / contraction packing is inflated and brought into close contact with the peripheral edge portion of the window glass by air pressure, a large load is not applied to the peripheral edge portion of the window glass unlike the conventional pressing mechanism. The frame for use can be omitted, and the structure can be further simplified.

According to the skylight of claim 2, since the expansion / contraction packing is made of a rubber tube, the airtightness and waterproofness can be improved at low cost.

According to the skylight of the third aspect, since the window frame is provided with the fixed packing at a position facing the expansion / contraction packing with the window glass interposed therebetween, the airtightness and waterproofness can be further improved.

According to the skylight of claim 4, since the window glass is provided so as to slide and open along the plane of the opening of the window frame, the window glass is rotated and opened and closed by a hinge. As a result, a mechanism for supporting the reaction force at the time of expansion of the expansion / contraction packing is not required, so that the structure can be simplified and the opening area can be increased.
