Description

[Detailed explanation of the idea] This idea is related to a structure for closing a daylight window from rain.

The lighting window rain closing structure, which is the basis of this invention, will be explained using FIGS. 1 to 3.

First, to explain the daylighting window, as shown in Fig. 1, this daylighting window A is made by fixing a metal window frame receiving material 2 with screws 3 on an opening frame 1 made of a square wooden frame. The lateral protrusion 2a of the window frame support 2 is fitted to the bearing 5a of the window frame 5 on which the glass 4 is fitted, so that the window frame 5 can be opened and closed using the protrusion 2a as a fulcrum. A telescopic opening/closing rod 6 is installed between the inner surface and the lower surface of the window frame 5 to control opening and closing of the window frame 5, and a locking mechanism B is provided on the open end side of the window frame 5 for locking and unlocking. I have to.

In this case, as shown in FIG. 2, a notch 7 is provided in the upper part of the inner surface of the opening frame 1, and an inner gutter 9 is attached using screws 8.

Further, a heat insulating material 10 is arranged between the window frame receiving material 2 and the opening frame 1.

Furthermore, the window frame 5 mainly consists of an outer frame 11 and an inner frame 12, which are connected by tapping screws 14 via a heat insulating sheet 13 made of hard PVC or the like.

By connecting the outer frame 11 and the inner frame 12, a groove 15 is formed on the inner circumferential surface of the opening, and the edge of the pair of glass glasses 4 is fitted into the groove 15 via a rubber 16 and a packing 17.

In this case, the pair of glass glasses 4 is constructed by laminating a tempered glass 4a and a wired glass 4b with a spacer 4c interposed therebetween.

Next, to explain the locking mechanism B, the approximately U-shaped metal fitting 1
A claw receiver 18 with a bar-shaped claw locking part 18b hooked between both sides of the claw holder 8a is fixed to the inner surface of the opening frame 1.

On the other hand, a long mounting auxiliary plate 19 is fixed along the lower surface of the inner frame 12 of the window frame 5 with bolts 20 and nuts 21, and a pair of metal fittings 22 (first
(see figure) so that they face each other, and these metal fittings 2
A rotating shaft 23 is passed between the two, and a substantially square-shaped engagement claw 24 is pivotally connected to the rotating shaft 23.

When the window frame 5 is closed, the claw portion 24a provided at one end of the engaging claw 24 is engaged with the claw locking portion 18b, thereby making it possible to lock the window frame 5.

Further, the ends of both sides of the U-shaped handle 25 are pivotally connected to the metal fitting 22 by a shaft 25a, and the center piece 25a is arranged below the other end 24b of the engaging claw 24.
By rotating the shaft 25a in the second fixing direction around the shaft 25a, the center piece 25b locks and pushes up the other end 24 of the engaging claw 24, and the engaging claw 24 is rotated around the rotating shaft 23 in the same way. By rotating counterclockwise, the claw portion 24a of the engaging claw 24 is disengaged from the claw locking portion 18b, and the lock can be unlocked.

A heat insulating sheet 2 is placed between the inner frame 12 and the mounting auxiliary plate 19.
Install 6.

In addition, a watertight rubber 27 is attached to the upper end of the window frame receiving material 2,
To ensure watertightness between a window frame receiving material 2 and a window frame 5 when the window frame 5 is closed.

In order to improve watertightness, a drain part 5b is integrally provided on the lower edge of the window frame 5, and a drain part 5b is provided on the outdoor side of the window frame receiving material 2, which is spaced apart from the outside of the opening frame 1. A portion 2b is integrally provided.

To install the lighting window A on the roof surface, as shown in Fig. 3a, an opening 28 is created in the exposed roof board by removing the tiles at the location where the lighting window A is planned to be installed, and the periphery of this opening 28 is The opening frame 1 is fixed to the upper surface of the base frame 29 as shown in FIG. A ri-shaped drain plate 30 is installed along the
As shown in FIG.
The window frame 5 is attached to the upper surface of the opening frame 1, as shown in FIG.

In this case, when installing the window frame 5, the upper end of the opening/closing rod 6 is fixed to the lower surface of the window frame 5 in advance at the factory as shown in FIG. The window frame 5 and the window frame support 2 are pivotally connected by fitting the protruding parts 2a of 2 into each other. At the site, as shown in FIG. At the same time as fixing it on the top surface of 1,
Construction is carried out by fixing the lower end of the opening/closing rod 6 shown in FIG. 1 to the inner surface of the opening frame 1.

In that case, as shown in FIG.
b is arranged at a distance on the outdoor side of the opening frame 1 so as to cover the upper end of the draining plate 30, so that the draining part 2b and the draining plate 30 can provide rain protection between the window frame receiving material 2 and the opening frame 1. let

As described above, the reason why the window frame receiving material 2 is fixed to the opening frame 1 and the daylighting window A is assembled on site is that if the daylighting window A is assembled in advance at the factory, the daylighting window A can be attached to the roof surface. This is because even if you try to install the draining board 30 along the outer surface of the opening frame 1 after installation, the draining part 2b of the window frame receiving material 2 will get in the way, making it impossible to work. As a result, on-site construction becomes complicated.

The above has explained the rain protection structure of a daylighting window with a window frame that can be opened and closed, but a similar problem can be solved with a daylighting window with a fixed window frame in which the window frame is directly attached to the top surface of the opening frame 1 instead of the window frame receiving material 2. This also occurs with closing structures.

Therefore, the purpose of this invention is to provide a daylight window rain closing structure that can simplify on-site construction regardless of whether it is a daylight window with a fixed window frame or a daylight window where the window frame can be opened and closed, and which is sure to prevent water leakage.

An embodiment of this invention will be described with reference to FIG.

That is, this daylighting window rain closing structure is applied to a daylighting window with a window frame opening/closing type, and instead of the window frame receiving material 2 having the water cutout part 2b shown in FIG. Using a window frame support material 2' having an outer flange 2a' for attaching the section, screw the upper back surface of the water section 33 with the elastic sealing material 32 adhered to the lower back surface to the outer flange 2a' via the rubber gasket 34 with a screw 35. By attaching it later, the tip of the elastic sealing material 32 is brought into pressure contact with the upper end of the draining plate 30.

In this case, the elastic sealing material 32 is formed using foamed urethane or the like.

At the upper end of the draining plate 30, there is a folded piece 30a facing outward diagonally downward.
The elastic sealing material 32 is brought into pressure contact with two places: the outer surface of the draining plate 30 and the tip of the folded piece 30a.

The rest of the configuration is the same as the prior art shown in FIG. 2, so the same parts are given the same reference numerals and the explanation thereof will be omitted.

As a result of this configuration, by attaching the window frame 5 to the opening frame 1 and assembling the daylighting window in advance in the factory, the daylighting window can be installed on the roof surface and the daylighting window can be assembled to the opening frame 1 at the site.
The work can be completed by simply attaching the water cutting board 30 to the outside surface of the window frame and then attaching the water cutting board 33 to the window frame receiving material 2'. can be simplified.

Moreover, since the upper back surface of the water cutter 33 is fixed to the outdoor surface of the window frame receiving material 2, the fixing work can be easily performed from the outdoor side of the daylight window.

In addition, since the water cutter 33 is placed outside the water cutter plate 30,
This water cutter 33 can, of course, prevent rain between the window frame receiving material 2' and the opening frame 1 in the same way as the water cutter 2b in FIG. Because of the pressure contact, it is possible to achieve better rain protection performance than the prior art shown in FIG.

In this case, a folded piece 30a facing outward diagonally downward is provided on the upper edge of the drain plate 30, and an elastic sealing material 32 adhered to the back surface of the drain plate 33 is placed between the outer surface of the drain plate 30 and the tip of the folded piece 30a. Since it is pressed into place and the water leakage route is double waterproofed, even more reliable watertightness can be achieved.

In particular, in the pressure contact portion with the folded piece 30a, the folded piece 30
Due to the elasticity of both the elasticity of a and the elasticity of the elastic sealant 32, the elasticity of the elastic sealant 3 changes over time.
High watertightness can be obtained despite the decrease in elasticity etc. of No. 2.

Furthermore, although it is double waterproof, only one elastic sealing material 32 is required, so the structure and construction are simple.

On the other hand, since the daylighting window can be assembled in advance at the factory, it is possible to attach the window frame receiving material 2' to the opening frame 1 and to attach the opening/closing rod 6 (Fig. 1) between the window frame 5 and the opening frame 1. can be performed with high precision in the factory, and the locking/unlocking operation by the locking mechanism B can be performed smoothly.

Another embodiment of the second invention will be described with reference to FIG.

That is, this daylighting window rain closing structure is applied to a daylighting window with a fixed window frame, and as shown in the figure, the window frame 5'
An outer flange 5a' for attaching a water section is formed on the lower edge of the outer frame 11 on the outdoor side, and the upper back surface of the water section 33' is fixed to the outdoor surface of the outer flange 5a' with a screw 35' via a rubber gasket 34'. Accordingly, the elastic sealing material 32' adhered to the lower back surface of the water cutter 33' is pressed against the water cutter plate 30.

In this case, the lighting window is constructed by fixing the inner gutter 37 to the inner gutter fitting recess 36 formed in the upper part of the inner peripheral surface of the opening frame 1' with wood screws 38, and connecting the inclined connecting piece 37a provided on the inner gutter 37 to the window frame 5. Connect the inclined connected piece 5b' provided at the screw 40 through the spacer 39.
By connecting the window frame 5' to the opening frame 1', the window frame 5' is fixed to the opening frame 1'.

Further, a gasket 41 is interposed between the window frame 5' and the opening frame 1'.

Since the other configurations are the same as those of the above embodiment, the same parts are given the same reference numerals and the explanation thereof will be omitted.

In this embodiment, as in the above-mentioned embodiment, the window frame 5' is attached to the opening frame 1' in advance to assemble the daylighting window at the factory. The work can be completed by simply installing the drain plate 30 along the outer surface of the frame 1' and then attaching the drain strip 33' to the window frame 5', thereby simplifying the on-site construction.

As mentioned above, according to the lighting window rain closing structure of this invention,
This has the effect of simplifying on-site construction and ensuring reliable rain control performance.
