Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skylight opening / closing structure in which a shoji is opened and closed with respect to a window frame in a hinged manner mainly by a hinge portion formed on a ridge side.

[0002]

2. Description of the Related Art Skylights are provided horizontally in the girder direction and in accordance with the roof slope in the beam-to-beam direction, that is, parallel to the roof surface. However, in reality, due to construction errors, etc., even if the girder direction is parallel to the roof surface, the girder direction is often slightly inclined from the horizontal direction. Is biased to the left or right. Therefore, by repeating the opening / closing operation, a force in the thrust direction is applied to the hinge member that connects the window frame and the frame of the shoji, and the position of the shoji shifts and the sealing performance deteriorates at the time of blockage, or the window frame and shoji screen are closed. There is a risk that it will be damaged due to the intersection with the frame.

As a structure for opening and closing a skylight that solves such a problem, a structure disclosed in, for example, Japanese Utility Model Publication No. 57-59531 is known. This skylight consists of a window frame and shoji that are each made of extruded aluminum, and the shoji is installed on the wing side of the skylight, that is, between the upper frame of the window frame and the upper frame of the shoji. Centering around the hinge member
It is designed to open and close in the form of a hinged door. in this case,
The skylight is closed so that the lower end of the frame of the shoji frame fits into the upper end of the window frame, and the overlapping part of the upper end of this window frame and the lower end of the frame is located on both sides of the window frame. A guide protrusion is provided on the side of the eaves. The shoji is guided by the swing stop member to be opened / closed and closed in the swing stop state.

[0004]

In such a conventional opening / closing structure, the steady rest functions effectively when the shoji is closed, but the rest member and the frame of the shoji cannot contact each other, that is, the shoji screen. During the opening and closing operations of the hinge member, the hinge member receives all the force in the thrust direction based on the load of the shoji screen and the wind pressure. For this reason, when the hinge member is in the open state, it is distorted by the force in the thrust direction, and as a result, the window frame and the frame of the shoji may cross each other, resulting in damage or defective closing.

The present invention has been made in view of the above problems, and by constructing a swing stop with a simple structure, it is possible to prevent the window frame and the frame of the shoji from crossing each other. Its purpose is to provide an opening and closing structure.

[0006]

In order to achieve the above object, the present invention is opened and closed centering around a hinge portion, and the lower portions of both side frames of a shoji overlap and are closed on the outside of the upper portions of both side frames of a window frame. In the opening and closing structure of the skylight, a swinging member that guides the lower part of each side frame when opening and closing the shoji is projected on the ridge side and the eaves side above each side frame. .

In this case, the window frame is composed of an upper frame and a lower frame with both side frames being four-sided frames, and the anti-vibration member is a fixing screw for a frame structure for fixing each side frame to the upper frame and the lower frame. The head is preferably

In these cases, the shoji frame is constructed by assembling frame members in four directions. The lower part of the frame is a circular arc which serves as a pivot for the hinge part as well as a guide portion for the anti-sway member. It is more preferable that the portion is formed.

[0009]

According to the structure for opening and closing a skylight of claim 1, a swing stop member for guiding the lower part of each side frame of the shoji is provided on the ridge side and the eaves side above each side frame of the window frame when opening and closing the shoji. Since they are projected respectively, when opening and closing, the position of the shoji in the girder direction (left and right direction) can be guided not only on the eaves side but also on the ridge side, and the left and right runout can be corrected at two front and rear positions. it can. This can correct the shake not only when the shoji screen is closed, but also during the opening / closing operation. Also, when the position of the sway member on the ridge side is close to the hinge part, and when the opening / closing angle of the shoji is relatively small, the lower part of the side frame of the shoji screen on the ridge side is in contact with the anti-sway member. Since the state (overlapped state) is maintained, even if the shoji screen is in the open state, the shake is corrected by the sway stop member on the ridge side.

According to the opening / closing structure of the skylight of claim 2, the window frame is constituted by an upper frame and a lower frame with both side frames being four-sided frames, and the swing stop member has each side frame as an upper frame and an upper frame. Since it is composed of the head portion of the fixing screw for the framework that is fixed to the lower frame, the fixing screw for the framework can be used also as the damping member without preparing a damping member. By using a round screw or a round screw with a round head as the fixing screw, the opening / closing resistance of the shoji can be reduced, and the shoji can be smoothly opened / closed without impairing the swinging function. .

According to the opening / closing structure of the skylight of claim 3, the frame of the shoji is formed by assembling frame members in four directions, and an arc portion serving as a rotation axis of the hinge portion is provided at a lower portion of the frame. Since it is formed, the rotary shaft of the hinge part and the part to be guided to the anti-sway member can be formed at the same time as the shape member. It functions to make the switching resistance smaller.

At both ends of each of these screw holes 26, a pair of left and right parts for framing the metal frame 6 are provided. The fixing screws 11, 11 are screwed together (see FIG. 2).

On the outer side of the outer piece portion 24, the draining frame 1 is provided.
2 is attached, and the draining frame 12 is suspended around the metal frame 6 so as to cover the upper half of the wooden frame 5.
In this case, the ridge-side portion of the metal frame 6, that is, the metal upper frame 6
In the outer piece 24 of b, the draining frame 12 is the hinge receiving member 1
With 0 pinched, it is fixed with screws.

The hinge receiving member 10 is made of an extruded aluminum material or the like and is formed to be somewhat shorter than the upper metal frame 6b. One end of the hinge receiving member 10 in the cross-sectional direction is hooked on the upper piece 22 (the screw hole 26a) of the metal upper frame 6b, and the other end is between the outer piece 24 of the metal upper frame 6b and the draining frame 12. It is pinched. An arcuate hinge receiving portion 10a is formed upward at an intermediate portion of the hinge receiving member 10, and the ridge side of the metal frame 8 of the shoji 4 is rotatably locked to the hinge receiving portion 10a.

On the other hand, as for the wooden frame 7 of the shoji 4, the side frames 7a and 7a, the upper frame 7b on the ridge side and the lower frame 7c on the eaves, which are cut at 45 degrees at their respective ends, are frame-shaped. And similarly, the metal sill 8 has 45 ends at each end.
Both metal side frames 8a, 8a, metal upper frame 8b, which are cut once
And the lower metal frame 8c are framed in a rectangular shape.
The wooden frame 7 is a piece of wood with a certain thickness and has an inverted "L" cross section.
The upper piece portion 22 of the metal frame 6 is formed so as to face a pocket formed in a letter shape and open to the outside. And wooden frame 7
A metal frame 8 made of extruded aluminum or the like is screwed to the upper end of the.

The metal frame 8 has a hollow portion 31 in the cross-sectional direction,
The hollow piece 31 has a pressing piece portion 32 that extends inward from the upper end, an outer piece portion 33 that extends outward from the hollow portion 31, and a lower piece portion 34 that extends downward from the hollow portion 31. 34
An arc portion 34a is formed at the lower end portion of the. The arcuate portion 34a functions as a rotating shaft for rotatably supporting the shoji 4 on the hinge receiving member 10 in the portion of the upper metal frame 8b, and in other portions of the metal side frame 8a and the lower metal frame 8c. It functions as a water repellent member and a contact portion with a vibration-proof member described later. In addition, the pressing piece 32 of the metal frame 8 and the wooden frame 7
A mounting groove 13 is formed between the upper surface and the upper surface of the multi-layer glass 9 and is fixed to the mounting groove 13.

On the other hand, the upper end of the hollow portion 31 of the metal frame 8 and the outer piece portion 33 have screw holes 35 whose lower surfaces are open,
35 are provided respectively. Each screw hole 35
In the same manner as the metal frame 6, both metal side frames 8a, 8a
A pair of left and right fixing screws 14 and 14 for assembling the upper metal frame 8b and the lower metal frame 8c are screwed together (see FIG. 2).

Here, the main part of this embodiment will be described in detail. The shoji screen 4 is opened at an angle of approximately 30 degrees with respect to the window frame 3 around the hinge receiving member 10, and the upper piece part 22 that constitutes the upper end part of the window frame 3 is connected to the lower part that constitutes the lower end part of the shoji screen 4. The piece 34 is closed so as to overlap in the vertical direction. As shown in FIG. 3, in the upper piece portion 22 of the window frame 3, the metal side frames 6a are respectively provided at two locations on the ridge side and the eaves side (a total of four locations on the left and right sides) of the metal upper frame 6b and the metal lower frame. Fixing screws 11a for fixing to 6c are provided respectively, and in the closed state, formed on the lower piece portion 34 of the shoji 4 outside the four fixing screws 11a as shown by imaginary lines. The circular arc portions 34a are located close to each other. That is, each of the fixing screws 11a is formed of a round screw, the head is projected from the metal side frame 6a, and the upper end of the back surface of the head is arranged to be the same as the upper end of the upper piece portion 22,
It constitutes a vibration-proof member for the shoji screen 4.

As shown in FIG. 4, during opening / closing operation (1
Even if it is opened 5 degrees), the lower end of the metal side frame 8a of the shoji 4, that is, the lower end of the arc portion 34a is the fixing screw 1 on the ridge side.
1a has a swinging function, and although not shown in particular, the lower end of the metal side frame 8a of the shoji 4 is located at the upper half of the ridge-side fixing screw 11a even when the shoji 4 is fully opened. Therefore, the anti-swing function is not impaired not only when opening and closing but also in the open state.

As described above, according to this embodiment, the upper fixing screw 1 for the frame projecting to the ridge side and the eaves side of each metal side frame 6 is formed.
Since the round head of 1a is made to function as an anti-shake member of the shoji 4, the anti-shake member of the shoji 4 can be constructed by simply forming the fixing screw 11a with a round screw. Further, since the shoji screen 4 is guided by the fixing screw 11a on the ridge side and the eaves side, the shoji screen 4 is corrected in its lateral position regardless of whether it is closed, opened or closed, or opened. For this reason, even if the girder direction of the skylight 1 is installed with an inclination, and the force in the thrust direction acts, it is possible to prevent the window frame 3 and the frame of the shoji 4 from intersecting.

On the other hand, since the circular arc portion 34a of the metal frame 8 is used as a portion for contacting (guiding) the fixing screw 11a, a shaft portion for opening and closing the shoji 4 is used as a shape member for the metal frame 8. , And a guide portion to the fixing screw 11a can be formed at the same time, and a useless portion of this profile can be utilized. Moreover, since the part that guides the fixing screw 11a is rounded, it is possible to prevent a blocking failure such as the shoji 4 running on the head of the fixing screw 11 at the time of blocking, together with the round head of the fixing screw 11a. In addition, the opening / closing resistance can be reduced, and the shoji screen 4 can be smoothly opened and closed.

In the present embodiment, the vibration-proof member is
The fixing screws for the frame are also used, but as long as they are provided on the ridge side and the eaves side of each side frame, a dedicated anti-vibration member may be provided, and their shape and material are arbitrary.

[0025]

As described above, according to the skylight opening / closing structure of the present invention, the position of the shoji in the column direction with respect to the window frame can be prevented by the swinging members provided on the ridge side and the eaves side regardless of the open / closed state of the shoji. Therefore, even if a force in the thrust direction is applied, this can be prevented with a simple structure to prevent the window frame and the frame of the shoji from intersecting and being damaged. Therefore, it is possible to configure a skylight having low cost, durability, and sealing properties.
