Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to skylights used on the roofs of main houses and lower buildings, sunrooms, greenhouses, assembly houses, etc. This invention relates to a skylight with a multi-layer structure in which a transparent plate and a lower transparent plate are attached to a skylight frame in an inclined manner.

(Prior art and its problems) When ordinary glass plates are used for both the upper and lower parts of a skylight with a multilayer structure, the glass plates are generally easy to break and the pieces fall and scatter indoors, which is dangerous. For the lower part, a glass plate with a wire mesh is generally used as a protective plate.

Conventionally, in the case of this type of skylight, the upper glass plate is fitted into the glass fitting groove provided on the upper side of the main frame through a gasket, and the lower glass plate is fitted onto the outer periphery of the glass fitting groove. Attach the periphery of the front, left, and right edging materials to a frame via a gasket, and fit the lower glass plate with the periphery into the recessed step recessed on the lower side of the main body peripheral frame and fix it as appropriate with screws, etc. I try to do that.

However, if the lower glass plate is attached to the main body frame by attaching its periphery to the outer periphery as described above, condensation water that has condensed and dripped on the lower surface of the upper glass plate or the upper and lower glass Rainwater that happens to enter between the panels from the outside flows down on the surface of the lower glass panel, but is blocked by the lower edge material of the periphery at the downstream end and is collected there and drained to the outside. However, if it remains stored for a long period of time, there are problems in that it corrodes the edge material and even the peripheral frame of the main body, and also stains the lower glass plate with the dust and dirt that has entered between the upper and lower glass plates.

(Technical means for solving the problem) The present invention was made to solve the above-mentioned conventional problems, and the technical means is to replace the upper transparent plate with a glass plate and the lower transparent plate. The plate is a plastic plate, the body peripheral frame is composed of at least an outer peripheral side wall and a support piece projecting inward from the outer peripheral side wall, the peripheral edge of the glass plate is attached to the upper side of the support piece, Attach the peripheral edge of the plastic plate to the lower side of the support piece, provide a gap between the lower side edge of this plastic plate and the support piece, and then attach the peripheral edge of the plastic plate directly below the lower side edge of this plastic plate to the support piece. A feature is that a facing gutter-shaped receiving frame portion is provided in the skylight frame.

(Example) Next, an example in which a skylight according to the present invention is installed on the entire roof of a sunroom, for example, will be described based on FIGS. 1 to 3.

In these figures, 1 is a continuous skylight, and the first
As is clear from the figure, it consists of three skylight sections 2a, 2b, and 2c that are arranged side by side in the left and right direction, and these skylight sections 2a, 2b, and 2c have skylight bodies 3a, 3b, and 3c, respectively. , these skylight bodies 3a, 3b, and 3c are each attached to a skylight frame 4 in an inclined manner to form a skylight 1. In addition, the skylight bodies 3a, 3b, and 3c each have a body peripheral frame 5.
It is composed of a rectangular upper translucent glass plate 6 and a lower translucent plastic plate 7 equipped thereon. The lower translucent plastic plate 7 is made of polycarbonate, for example.

To explain the above structure in more detail, each body peripheral frame 5 constituting each of the skylight bodies 3a, 3b, and 3c has an upper side frame portion 8a and a lower side frame portion 8b.
and left and right side frame parts 8c, 8c are assembled into a rectangular shape, and the upper side frame part 8a is formed by framing the outer peripheral side wall 8.

It is composed of a rising wall _8a4 extending inwardly in a curved manner, and the lower side frame portion 8b hangs down from the lower end of the outer circumferential side wall _8b1 , the support piece _8b2 , the upper side wall _8b3 , and the outer circumferential side wall _8b1 . _Furthermore , the left and right side frame portions 8c are composed of an outer peripheral side wall 8c _1.
It is composed of a support piece 8c ₂ , an upper side wall 8c ₃ , and a drainage wall 8c ₄ . Support pieces 8a ₂ , 8b ₂ , 8c ₂ , 8c ₂ in the main body peripheral frame 5 and the upper side wall 8
The peripheral edge of the upper translucent glass plate 6 is inserted between a ₃ , 8b _{3 ,} 8c ₃ , and 8c 3 and sealed with caulking material 9 and rubber packing 10 . Also, the third
As shown in the figure, the lower translucent plastic plate 7
A convex fitting member 11 made of metal or plastic and having a substantially horizontal L-shaped cross section is attached to the left side edge 7c of the convex member 1 with a screw 12.
The tip end portion 11a of 1 is formed to be inclined upward, and this inclined tip portion 11a is connected to the left side frame portion 8c.
The support piece 8c ₂ is fitted into a recessed fitting part 13 integrally formed on the lower surface side of the plastic plate 7, and the right side edge 7d and the upper side edge 7 of the plastic plate 7.
a is attached to mounting pieces 15 and 16 that are attached to the support wall 8c ₂ of the right side frame portion 8c and the support piece 8a ₂ of the upper side frame portion 8a with screws 14, respectively, using screws with knobs 17 as fixing devices. Fixed. In addition, a gasket 1 is attached to the lower surface of the support pieces 8a ₂ , 8b ₂ , 8c ₂ , 8c ₂ .
8 are attached to ensure a seal between the circumferential edges 7a, 7b, 7c, 7d of the plastic plate 7. However, the above plastic plate 7
When attaching, bring this plastic plate 7 to the bottom side of the main body peripheral frame 5 and support the tip 11a of the convex member 11 attached to the left side edge 7c. The mounting piece 15 is inserted into the concave hooking receiving part 13 of the piece _8c2 , and the right side edge 7d of the plastic plate 7 is pulled to the right in FIG. After that, the upper side edge 7a can be similarly fixed to the mounting piece 16 with screws 17.To remove this plastic plate 7, simply loosen and remove the screws 17. Plate 7 is support piece 8
It can be easily separated from a ₂ , 8b _{2 ,} 8c 2 , and 8c ₂ . During the above installation, since the tip 11a of the convex hooking member 11 and the bottom surface 13a of the concave hooking receiving part 13 are sloped, the left side edge 7c of the plastic plate was screwed with a screw. As in the case, it can be pressed against the support piece 8c ₂ and firmly fixed. Note that the lower side edge 7b of the plastic plate 7 has a gasket 18 between it and the support piece _8b2 .
Although it does not have any fixing means to the supporting piece _8b2 , it is possible to form a gap between the upper surface of the lower side edge 7b and the lower surface of the packing 18, so that the internal accumulation can be removed from the gap. This is done by actively discharging ivy, debris from the upper translucent glass plate 6, and condensed water. Incidentally, the above-mentioned gap is inevitably formed due to the bending of the plastic plate 7 under normal conditions. In addition, the support piece 8
b ₂ The gasket 18 on the lower surface side may be completely omitted or may be provided in sections, thereby creating a wider gap and draining glass fragments and condensed water more effectively. However, there is a disadvantage that the heat insulation effect due to the air layer between the glass plate 6 and the plastic plate becomes worse.

On the other hand, the skylight frame 4 to which the above-mentioned skylight bodies 3a, 3b, and 3c are attached has an upper side stile 19, a lower side stile 20, left and right side stile 21, 21, and an intermediate part between these left and right side stile 21, 21. It is composed of intermediate frames 22, 22 arranged in parallel, and a receiving plate 23 having a wider width is attached to the lower surface of each intermediate frame 22.

The gutter-shaped receiving frame portion 25 is positioned directly below the lower side edge 7b of the lower translucent plastic plate 7, more precisely, directly below the edge of the lower side edge 7b. When the upper translucent glass plate 6 is broken for some reason, the glass fragments are removed from the upper surface of the lower plastic plate 7. The pieces are then lowered and dropped through the gap between the lower side edge 7b of the plastic plate 7 and the packing 18, and are caught in the gutter-shaped receiving frame 25 to prevent the pieces from scattering into the room. . In addition, this gutter-shaped receiving frame part 25 not only holds glass fragments, but also
It can also receive condensed water that adheres to the lower surface of the glass plate 5 and flows down, as well as rainwater that has entered the inside of the skylight main bodies 3a, 3b, and 3c. Mouth 26,
It will be discharged outdoors via 27. The left and right side frames 21 include a mounting wall 21a that is attached to the upper end of the sunroom frame V, and a receiving wall 21 that protrudes upward from the outer end of the wall for supporting the skylight body.
It is composed of b. Further, each intermediate frame 22 has an inner wall portion 22a and an outer wall portion 2, each having a U-shaped cross section.

The skylight main body 3c is the same as the above-mentioned skylight main body 3a, but in the case of the skylight main body 3b arranged between these, the support pieces 8c ₂ and 8c ₂ on the main body peripheral frame 5 side are attached to the intermediate frames 22 on both sides. , 22, and the mounting conditions are slightly different in that they are respectively placed on the upper end surfaces of . In addition, when installing these skylight bodies 3a, 3b, 3c, the skylight frame 4
A gasket 32 is attached to the upper end surface of each of the side receiving walls 19b, 20b, 21b and the upper end surface of the intermediate stile 22, and as is clear from FIG. A gasket 33 is attached to the opposing surfaces of the outer peripheral side walls 8c ₁ and 8c ₁ of the mating frame portions 8c and 8c, respectively, and as is clear from FIG. A fin-shaped draining piece 34 made of an elastic material such as a comb is provided on the lower surface side of the sill 31 to protrude downward to prevent rainwater etc. from entering the inside of the upper side stile 19.

The skylight main bodies 3a, 3b, and 3c are attached by attaching an angled mounting piece 35 to the inner surface of the receiving wall portion 20b of the lower side stile 20 in the skylight frame 4, as shown by imaginary lines in FIG. Each body peripheral frame 5 through the piece 35
By fixing with screws, it can be made into a fixed type skylight, or if such a fixing means is not attached, the tip of the rising wall _8a4 of the upper side frame part 8a of each main body peripheral frame 5 can be fixed. It can also be a skylight with a pivot that can be opened and closed.

(Effects of the invention) According to the skylight of the invention, the main body peripheral frame is composed of at least an outer peripheral side wall and a support piece protruding inward from the outer peripheral side wall, and the peripheral edge of the plastic plate is attached to the lower surface side of the support piece. At the same time, a gap is provided between the lower side edge of this plastic board and the support piece, and a gutter-shaped receiving frame part facing directly below the lower side edge of this plastic board is provided on the skylight frame. Therefore, condensed water that condenses and drips on the lower surface of the upper glass plate, or rainwater that enters between the upper glass plate and the lower plastic plate from the outside, flows down on the lower plastic plate and is discharged downstream. If the dust is discharged downward from the lower side edge of the plastic plate surface through the gap with the support piece without accumulating, and if dust or dirt has accumulated between the upper glass plate and the lower plastic plate. The dust, etc. is washed away from the lower plastic plate surface along with dew condensation water and rainwater, and the dew condensation water, rainwater, dust, etc. discharged in this way are collected by the gutter-shaped receiving frame, and are thereby collected indoors. flow is prevented.
Furthermore, even if the upper glass plate is broken and its fragments flow out from the gap, they are received in the gutter-like receiving frame, preventing them from scattering indoors, ensuring safety.

In addition, in the present invention, a plastic plate is particularly used as the lower transparent plate, but this plastic plate not only functions as a protective plate like a glass plate with wire mesh, but also serves as a protective plate for the peripheral part of the main body. When attaching the plastic plate to the lower surface of the support piece, the peripheral edge of the plastic plate can be directly attached to the support piece using screws, etc., without intervening the peripheral edge, etc., making the installation work easier and ,
It has the advantage of reducing costs because it eliminates the need for mounting parts such as the periphery, and since the plastic plate has greater flexibility than the glass plate, it is easy to form a gap between the bottom surface of the support piece of the main body frame. There are possible advantages.
