Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a skylight that opens and closes a window hole opened on a rooftop surface by raising and lowering the window plate while maintaining a horizontal position.

Skylights, which are opened and closed by raising and lowering the window board while maintaining a horizontal position, are less susceptible to rain when the window is opened, compared to conventional skylights, which are opened and closed by tilting the window board around one side. Although it has the advantage of less falling down, it has the disadvantage that the mechanism for raising and lowering the window board horizontally is complicated and requires a long time to install.

An object of the present invention is to facilitate the assembly work at the site by constructing an assembly in which the elevating mechanism can be transported and assembled as one unit.

Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

A fixed frame 1 is fixed around a square window hole transparently provided on a horizontal roof surface, and an elevating frame 2 is attached to the upper surface of the fixed frame via two sets of elevating mechanisms 3.

The lifting mechanism 3 is an assembly that can be carried in the state shown in FIG.
Two X-shaped link mechanisms 30, 30, which are connected by a support shaft 49, are arranged parallel to each other with a gap between them, and a connecting rod 33 is inserted between the lower ends of the corresponding links 31, 31. The lower end of one of the links 31, 31 is rotatably connected to two brackets 35, 35 which are connected together and bent into an L-shape by a hollow shaft 34, The upper ends of the other links 32, 32 are rotatably connected to one end of the upper rails 38, 38 by a shaft 37, and these upper rails 38, 38
A roller 36 rotatably supported by a shaft 40 at the upper end of the one link 31, 31 is fitted into a guide groove 39 formed on the inner surface of the A roller 44 rotatably supported by a shaft 43 is attached to the upper rail 3.
8, 38, and two torsion bars 45, 45 made of spring steel are fitted diagonally between the brackets 35, 35. Each torsion bar 45 is fixed by fitting a downwardly curved hook at one end into a cylinder 29 fixed to one bracket 35, and a hook at the other end bent upward. The portion 46 is passed through the hollow shaft 34 and the distal end thereof is fitted into a small hole 47 formed in the one link 31 to be fixed.

The two sets of elevating mechanisms 3, 3 having the above configuration are arranged on both the front and rear sides of the fixed frame 2, and the brackets 35, 35 are fixed to the inner surfaces of the front and rear frame members by bolts inserted into screw holes 50. Lower rails 41, 41 are fixed to the inner surfaces of the left and right frame members by bolts 51, and upper rails 38, 38 are fixed to the inner surfaces of the left and right frame members of the elevator frame 2 by bolts 52. .

A wired glass plate 21 is stretched inside the lifting frame 2, and a dome 22 made of a semi-transparent acrylic plate for limiting the amount of sunlight is attached to the top surface of the glass plate 21. One end of 23 is fixed frame 1
The wire 23 is fixed to the center of the right frame member of the elevator frame 2 by a metal fitting 24, and the wire 23 is passed through turning pulleys 25 and 26 that are pivotally supported at the center of the left and right frame members of the elevator frame 2, and is then moved indoors. It hangs down, and its end is connected to a winding device (not shown).

Next, the operation of this embodiment will be explained.

Wire 23 by rotation of motor or handle
When the rollers 36 and 44 roll in the guide grooves 39 and 42 and the links 31 and 32 of each link mechanism 30 and 30 tilt in the direction in which they fall down, the elevator frame is 2 descends, each torsion bar 45 is twisted by the tilting of the one link 31, and a torsion force in the opposite direction is accumulated, and when the elevating frame 2 comes into close contact with the fixed frame 1 and the window hole is closed, the winding is started. The device is locked and held in that state. When the winding device is unlocked and the wire 23 is let out in this closed window state, one link 31 of each link mechanism 30 is tilted in the direction of standing up due to the elastic restoring force of the torsion bars 45, 45, and the other link 32 is also tilted in the upright direction in conjunction with this, so that the elevating frame 2 is lifted away from the fixed frame 1, and the window is opened.
42 in the opposite direction.

In the above embodiment, since the one link 31 of the left and right link mechanisms 30, 30 corresponding to each other is connected by the connecting rod 33, the left and right link mechanisms 3
0 and 30 operate in an orderly manner, and the lifting frame 2 is raised and lowered while maintaining a horizontal position. Also, one end of the wire 23 for opening/closing operation is fixed to the fixed frame 1, and this wire 23 is connected to the corresponding part of the lifting frame 2. Since the other end of the wire 23 is hung indoors by hanging it around turning rollers 25 and 26 which are pivotally supported at the center of the two sides, the tensile force of the wire 23 acts equally on the two corresponding sides of the lifting frame 2, preventing it from tilting. Furthermore, since the torsion bar 45 is used to store the force for raising the lifting frame 2, it has the advantage of being able to be stored in a small space along the fixed frame 1 and storing a large fenestration force. be.

In this embodiment, as a mechanism for raising and lowering the lifting frame 2 while keeping it in a horizontal position, an

44 side may be removed to create a λ-shaped or reverse λ-shaped link mechanism. In this case, the removed link 3
The rail 3 to which the rollers 36 and 44 of 1 and 32 fit
8 and 41 are no longer necessary, and when the upper rail 38 is removed, the upper end of the other link 32 is directly pivoted to the lifting frame 2. Further, instead of the rollers 36 and 44, the links 31 and 32 may be pivoted to sliding bodies that slide along the guide grooves 39 and 42.

Furthermore, only one lifting mechanism 3 may be installed in one skylight, or three or more lifting mechanisms 3 may be installed.

As specifically explained in the above embodiment,
The skylight of the present invention is provided by fixing a flat rectangular fixed frame around a transparent window hole in a substantially horizontal roof surface, and extending a window plate to an elevating frame that aligns with the upper surface of the fixed frame. In a skylight in which the window hole is opened and closed by raising and lowering the frame while keeping it in a horizontal position, two link mechanisms each consisting of a pair of links that tilt in conjunction with each other around a support shaft are used to correspond to each other. An elevating mechanism is formed by connecting links that are connected to each other with connecting rods, and a torsion bar is attached to at least one of the link mechanisms to bias the link mechanism in an upright direction, and the assembly is made up of one or more The gist is that two or more tension devices are interposed between the fixed frame and the lifting frame and pull the lifting frame downward, and the corresponding links are connected to each other by connecting rods. Since they are connected, the two link mechanisms work together to raise and lower the lifting frame 2 while maintaining its horizontal position.Also, since the torsion bar is used to store the force to raise the lifting frame, it moves along the fixed frame. Furthermore, since the lifting mechanism is made into a single assembly, it is possible to achieve uniform quality and reduce costs by mass producing it at the factory and sending it to the construction site. This simplifies the assembly work on site and has the effect of significantly shortening the construction period.
