Description

[Detailed description of the invention] [Technical field] This invention relates to a rain protection structure for a skylight.

[Background technology]

The base end of the window frame is held by a hinge mechanism installed on the outer periphery of one frame member of the opening frame, allowing it to rotate freely around an imaginary rotation axis parallel to the one frame member and slidably in the longitudinal direction of one frame member. In conventional skylights, an upright piece is installed on the outer periphery of the upper surface of the opening frame, and a water cutter is installed vertically on the outer periphery of the lower surface of the window frame. At the same time, a water interceptor is placed to cover the outside of the upright piece to prevent rain.

However, because the upright piece and water section were provided, the upward opening angle of the window frame was small, that is,
There is a problem in that even if an attempt is made to open the window by sliding it sideways when the angle formed between the window frame and the opening frame is relatively small, the upright piece and the water section engage with each other at the base end of the window frame, making it impossible to open the window. was. Note that if a notch is formed in the lower region of the water section corresponding to the upright piece on the base end of the window frame, the upright piece can be inserted into the notch and the opening angle of the window frame upward relative to the horizontal line can be adjusted. It is possible to open the window by sliding it to the side when the window is at 0 degrees, but in that case, when the window is closed,
There is a possibility that rainwater may enter the skylight through the notch.

[Purpose of invention]

The purpose of this invention is to provide a skylight which can be slid open laterally with an upward opening angle of 0 degrees relative to the horizon, and which also has excellent rainwater drainage performance when the window is closed.

[Disclosure of invention]

This idea allows the base end of the window frame to freely rotate around an imaginary axis of rotation parallel to the frame member and in the longitudinal direction of the frame member, using a hinge mechanism installed on the outer periphery of one frame member of the opening frame. The skylight is slidably held, and includes an upright piece that stands along the outer periphery of the upper surface of the opening frame and contacts the lower surface of the window frame when the window frame is closed; A water section is installed vertically along the window frame and is arranged to cover the outside of the upright piece when the window frame is closed, and the upright piece is placed in correspondence with the upright piece parallel to the opening frame frame material on the proximal end of the window frame. It includes a notch formed in the lower region of the water section on an extension line in one longitudinal direction, and an elastic waterproof sheet disposed within the notch with its upper end connected to the upper end of the inner periphery of the notch.

An embodiment of this invention will be described with reference to FIGS. 1 to 11. As shown in Figs. 1 to 6, this skylight is constructed by a hinge mechanism 3 installed at the outer periphery of one frame member of the opening frame 2, so that the base end of the window frame 1 can be rotated virtually parallel to one frame member. It is rotatable around the axis (see Figure 6),
And one frame member is held so as to be slidable in the longitudinal direction (see Figs. 3 and 4).

To explain in detail, the opening frame 2 is fixed with screws 5 onto a wooden frame 4 installed on the roof, as shown in FIG.

A pair of hinge mechanisms 3 are installed on both sides of the opening frame 2, as shown in FIG. 1 (one hinge mechanism is not shown). A perspective view of the main parts of this hinge mechanism 3 is shown in FIG. In the figure, 6 is a case with a pair of vertical pieces 6a facing each other, and both vertical pieces 6a
A horizontal rotating shaft 7 is spanned between one end of the . 8 is the top piece 8
A cam with an inverted U-shaped cross section consisting of a and side pieces 8b,
One end side of both side pieces 8b is pivotally supported on the rotating shaft 7, and a cover 8c is attached to the other end side. Further, the outer peripheral curved surface on the other end side of the cam 8 is finished into a cam surface 9 in which the radius of curvature relative to the rotating shaft 7 gradually increases from the bottom to the top, and the rotating shaft 7 is set as the center of curvature at the center of both side pieces 8b. Arc-shaped guide holes 10 are formed facing each other. Then, by passing the angle regulating shaft 11 through both guide holes 10 and bridging between both vertical pieces 6a in a state parallel to the rotating shaft 7, the angle regulating shaft 11 regulates the rotation angle of the cam 8. .

On the other hand, on the inner surface of the other end of both vertical pieces 6a, sliding shaft guide grooves 12 are formed facing each other so as to extend in the radial direction with respect to the rotating shaft 7, and the sliding shaft 13 can be freely slid between these guide grooves 12. At the same time, a tension coil spring 14 is suspended between the sliding shaft 13 and the rotating shaft 7, and the sliding shaft 13 is brought into pressure contact with the cam surface 9.
This hinge mechanism 3 is installed at the mounting part 6 of the case 6.
b, 6c on both sides of the opening frame 2 (Fig. 1)
(Fig. 8).

A guide rail 16 is fixed to the upper piece 8a of the cam 8 with screws 17 as shown in FIG.
A traveling rail portion 18 provided on the base end side of the guide rail 16 is attached to the guide rail 16 via a ball bearing 19 so as to cover the guide rail 16. As shown in FIGS. 3 and 4, this guide rail 16 spans between a pair of hinge mechanisms 3 arranged on both sides of the opening frame 2, and allows the window frame 1 to slide freely along the guide rail 16. Hold.

To open the window 20 (consisting of the window frame 1 and the glass plate 21), the open end thereof is lifted as shown in FIG. This allows the window 2 to be added to the cam 8.
0 load decreases, the tension coil spring 14 contracts and draws the sliding shaft 13 toward the rotating shaft 7, and as a result, the sliding shaft 13 rotates along the guide groove 12 while contacting the cam surface 9. Move the cam 8
is lifted upward around the rotating shaft 7. When the window 20 is opened by 45 degrees, the angle regulating shaft 11 is engaged with the lower end of the guide hole 10, and further opening of the window 20 is restricted. In this state, when you release your hand from the window 20, the weight of the window 20 is applied to the cam 8 via the guide rail 16, and the cam 8 receives a force that rotates downward around the rotating shaft 7, but the window 20 does not open. In this state, the force acting on the cam 8 is smaller than when the window 20 is closed (FIG. 7), so the force that pushes the cam 8 upward by the tension coil spring 14 pushes the cam 8 downward. As a result, the window 20 does not fall down and remains open.

The features of this embodiment will be explained next. That is, as shown in FIGS. 2 to 4, and 7, the rising pieces 22a, 22b, 2
2c, and these rising pieces 22a, 22b, 22
Attach the packing 23 to the U-shaped holding part provided at the top of c. Further, a water section 24 is vertically provided along the entire outer periphery of the lower surface of the window frame 1. The relationship between the water intercept 24 and the upright pieces 22a, 22b, and 22c is such that when the window 20 is closed, the gasket 23 is attached to the lower surface 1a of the window frame 1.
(FIG. 2), and the water section 24 is placed to cover the outside of the upright pieces 22a, 22b, and 22c. In this way, waterproofing between the window frame 1 and the opening frame 2 is achieved when the window is closed.

In addition, as shown in FIGS. 1 to 3, in correspondence with the rising piece 22a parallel to the guide rail 16 on the base end side of the window frame 1, a water section 24 located on the longitudinal extension line of the rising piece 22a A notch 25 is provided in the lower region of the. Then, the upper end of an elastic waterproof sheet 26 made of rubber, resin, etc. is fixed to the upper end of the inner periphery of this notch 25 with adhesive or screws, and this waterproof sheet 26 is closed and placed inside the notch 25. .

In this way, since the notch 25 is provided in the water section 24, as shown in FIGS. 3 and 4, the upward opening angle of the window 20 with respect to the horizontal line is maintained at 0 degrees,
That is, it becomes possible to open the window 20 laterally while the window 20 is in a horizontal state. That is, the fifth
From the window closed state shown in the figure, lift the window 20 upward to the position where the water section 24 no longer engages with the upright section 22b (approximately 0 degrees with respect to the horizontal line), as shown in FIG. Slide the window 20 sideways along the guide rail 16 to a predetermined position while maintaining the opening angle, lower the window 20 downward again, and raise the open end of the window 20 to the corresponding position as shown in FIG. Piece 2
Place it on 2c. In this case, the upright piece 22a on the window base side enters into the notch 25, and the elastic waterproof sheet 26 is pushed by the upright piece 22a and turns upward, so the window 20 can be lowered downward without any hindrance. Can be done. In this way, with the upward opening angle of the window 20 maintained at approximately 0 degrees with respect to the horizontal line,
It becomes possible to open the window 20 laterally. In addition, since the elastic waterproof sheet 26 is disposed within the notch 25, when the window 20 is closed, the first,
As shown in Figure 2, the waterproof sheet 26 has a notch 25.
In order to cover the outside of the rising piece 22b,
Rainwater will no longer infiltrate into the skylight through the notch 25, and good rain shutoff performance can be obtained. Note that FIG. 11 is a schematic side sectional view showing the open state of the window 20 installed on the roof, and the opening angle of the window frame 1 is approximately parallel to the horizontal line.

According to the skylight of this invention, the window can be opened laterally with an upward opening angle of 0 degrees with respect to the horizon, and it also has the effect of being excellent in rain protection performance when the window is closed.
