Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a roof lighting window.

[0002]

[Prior Art]

 A roof lighting window may be provided on the roof of a building such as a wooden house having a certain slope so that daytime sunlight can be taken indoors. FIG. 5 shows a conventional example of such a roof lighting window. In the figure, reference numeral 25 is a base plate that constitutes the roof surface of the building, and a roof tile 27 is covered with a waterproof sheet 26 on the upper surface thereof. Reference numeral 28 denotes the roof daylighting window, which is a watertightly fitted window frame 29 in a window opening (not shown) provided on the base plate 25, and a window fitted so as to cover the window frame 29 from above. The roof lighting window 28 is provided so as to have a main body 30, and is so arranged as to be slightly projected from the roof tile 27.

Conventionally, both the window frame 29 and the window body 30 have a substantially rectangular shape in a plan view. Therefore, the roof daylighting window 28 has the window frame 29 and the left and right sides 31, 31 of the window body 30. 31 is parallel to the roof flow direction l _1, and their upper and lower edges 32 and 33 being disposed so as to be parallel to the direction l ₂ perpendicular to the roof flow direction l ₁ were common.

[0004]

[Problems to be solved by the device]

However, in the conventional roof daylighting window 28 described above, the upper side 32 of the window frame 29 and the window body 30 is oriented in the direction l ₂ orthogonal to the roof flow direction l ₁ , so that the vertical side surface of the upper side 32 of the window frame 29 is particularly In addition, fine dust and snow are likely to stay, so that the watertightness of the roof daylighting window 28 is often impeded by the corrosion from the upper side 32.

On the other hand, particularly in the case of cold district specifications, as shown in FIG. 5, a draining member 34 for snow splitting, which is bulged in a substantially triangular cone shape, is provided on the upper side of the upper side 32 of the window frame 29, and There is a technique for improving the drainage performance of the upper portion of the frame 29 to avoid the above-mentioned inconvenience, but if the special draining member 34 is provided in this way, it is not preferable in terms of construction cost and material cost.

[0006] In view of such circumstances, an object of the present invention is to provide a roof daylighting window which can be improved in waterproofness by a simple construction.

[0007]

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the technical means taken by the present invention is a shop installed slightly protruding from the roof tile 16 by fitting the window frame 4 into the window opening 3 provided on the base plate 2. In the root-lighting window, the upper part of the window frame 4 in the roof flow direction is formed so as to be parallel to the roof surface and inclined with respect to the direction l ₂ orthogonal to the roof flow direction l ₁ .

[0008]

[Action]

Since the upper part of the window frame 4 in the roof flow direction is inclined with respect to the direction l ₂ orthogonal to the roof flow direction l ₁ , fine dust and snow are prevented from remaining on the upper part of the window frame 4 and the upper part of the window frame 4 is prevented. Drainage performance is improved.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, reference numeral 1 denotes a roof daylighting window used in this embodiment. This roof daylighting window 1 is a window frame 4 fitted in a window opening 3 provided on a base plate 2 and the window. It has a window body 5 which is mounted on the frame 4 so as to be freely opened and closed.

The window body 5 has double inner and outer window glasses 6 and 7, and an opening / closing frame 9 that supports the window glasses 6 and 7 via a sealing material 8. The sealing material 10 is also interposed between the peripheral edges. The window frame 4 includes a wooden main frame 11 forming the outer periphery thereof, a wooden lower frame 12 fixed to the lower surface of the main frame 11, and a metal upper plate 13 forming the upper surface of the window frame 4. A decorative plate 14 is lined between the upper plate 13 and the lower frame 12. The window frame 4 is fixed by screwing the outer surface of the main frame 11 and the upper surface of the end portion of the base plate 2 with a mounting bracket 15 having an L-shaped cross section. 1 is installed so as to project slightly above the roof tile 16 around it.

Reference numeral 17 denotes a metal draining member, which has a draining plate portion 18 interposed between the base plate 2 and the roof tile 16 and a vertical side plate portion 19 that covers the outer surface of the main frame 11 and has a substantially L-shaped cross section. The window frame 4 is formed into a curved shape and is provided on the entire circumference of the window frame 4. Reference numeral 20 denotes a support member for the window body 5, which is fixed in a recess 21 provided at an upper corner of the main frame 11.

In this embodiment, as shown in FIG. 1, the window frame 4 and the window body 5 are formed in a substantially rhombic shape in plan view such that a pair of opposing upper and lower interior angles θ ₁ and θ ₂ are acute angles. Moreover, the pair of upper sides 22 and 23 sandwiching the upper interior angle θ ₁ of the window frame 4 and the window body 5 are arranged so as to be inclined with respect to the direction l ₂ which is parallel to the roof surface and orthogonal to the roof flow direction l _1. Has been done. It goes without saying that the window opening 3 is also formed in a rhombus shape along the rhombus of the window frame 4.

According to the present embodiment having the above-mentioned configuration, since the upper sides 22 and 23 of the window frame 4 and the window body 5 are inclined with respect to the direction l ₂ orthogonal to the roof flow direction l ₁ , the window frame 4 It is possible to prevent dust and snow from remaining on the upper sides 22 and 23 as much as possible, and improve the waterproofness of the roof daylighting window 1. Further, according to the present embodiment, the drainage performance of the upper part of the window frame 4 is improved by inclining the upper sides 22 and 23 themselves of the window frame 4, so that the conventional draining member for snow cutting is used. It is possible to perform the construction easily and inexpensively without the need to provide the construction, and it is possible to reduce the construction cost and labor.

The present invention is not limited to the above-described embodiment, and for example, as shown in FIG. 3, the window frame 4 may be formed in a pentagonal shape in which only the upper part thereof is inclined, and FIG. As shown in, only the upper portion of the window frame 4 may be formed in a semicircular shape.

[0015]

[Effect of the device]

 According to the present invention, dust and snow are prevented from staying above the window frame 4 in the roof flow direction, so that the waterproofness of the roof daylighting window 1 can be further improved and the window frame 4 itself can be inclined. Since the drainage performance of the upper part is improved, there is an advantage that construction can be performed easily and inexpensively.
