Description

[Detailed Description of the Invention] Industrial Application Field The present invention opens and closes a window hole opened in the roof of a building, etc. by means of a temporary window that moves up and down while maintaining a parallel attitude to a fixed frame fixed to the periphery of the window hole. Regarding the skylight.

Problems to be Solved by the Prior Art and Inventions Such skylights are constructed by fixing a rectangular fixed frame around the periphery of a window hole cut through the roof of a building, and attaching a rectangular fixed frame to the upper surface of the fixed frame. The window plate, which opens and closes the window hole by approaching and separating it, can be mounted freely up and down while maintaining a parallel position with the fixed frame using a parallel movement mechanism attached to the fixed frame. There is one in which the plate is separated from the fixed frame and urged in the upward direction, and the window plate is lowered against the urging force of the urging device, thereby drawing it to the upper surface of the fixed frame and closing the window. Conventionally, in order to lower the window panel against the biasing force of a biasing device, a wire rope is used, which supports turning pulleys at the center of each of the opposing edges of the window panel and connects one end to a fixed frame. By hanging the wire rope around these deflection pulleys and winding the other end of the wire rope around the winding drum, the central part of each edge of the window board is pulled against the biasing force of the biasing device. The window board was lowered by pulling it, but pulling only the central part of each of the edges of the five window boards in this way would cause problems, especially if there is large play in each part of the parallel movement mechanism. When the window panels were raised and lowered, they caused a large amount of shaking, which sometimes caused a rattling sound, making it impossible to operate the window panels stably.

Means for Solving the Problems As a means for solving the above-mentioned problems, the present invention provides a method in which one wire is connected to a fixed frame and an elevating frame, each of which has vertical tension portions formed at each of four corresponding corners. As shown in the figure, the wire is wrapped around a turning pulley that is pivotally supported by the fixed frame and the lifting frame, and the window is closed by pulling the wire.

Functions and Effects of the Invention The skylight of the present invention has the above-mentioned structure, and since the four corners of the elevating frame are each pulled with equal force by the vertical tension portion of the wire, the window plate is stabilized without shaking. As it moves up and down, the biasing force that biases the window plate is distributed to each vertical tension section, so the tension that acts on the wire becomes small, which makes it possible to reduce the wire diameter and reduce the tension of the wire. This has the effect that the device can be made smaller.

EXAMPLE Hereinafter, an example of the present invention will be described based on the accompanying drawings.

In the figure, l is a projecting wall formed around the periphery of a substantially square window hole cut through the roof of the building, and a fixed frame 2 is fitted onto the upper edge of this projecting wall l. On the top of 2,
A glass plate 5 is fitted inside a support frame 3 corresponding to the fixed frame 2, and the window plates 6 for opening and closing the window holes are mounted on the mutually opposing inner side surfaces of the fixed frame 2 by parallel movement mechanisms 8. It is mounted so that it can move freely up and down while remaining parallel to the fixed frame 2, and each parallel movement mechanism 8 has two equal-length links 10 and 11 that are connected at the center with a pin 9 and are connected to each other so that they can rotate freely. One end of one link 10 is connected to the shaft 1.
A slider 14 which is pivotally supported on the inner surface of the corner of the support frame 3 of the window plate 6 by 2 and protrudes from the other end is attached to the fixed frame 2.
As shown in FIG. 12 are fixed in parallel with each other at intervals, and a turning pulley 16 is supported between the surface support plates 12 and 12 by a shaft 15 that is fixed and penetrates through a shaft hole 14.14 provided in each support plate 12. The end of the link 11 is pivotally supported on the inner surface of the corner of the fixed frame 2 by the shaft 15 protruding to the outside of the support plate 12, and a shaft 15 is provided protruding from the other end. The slider 14 is slidably fitted into the guide groove of the same guide member 15 fixed inside the support frame 3 of the window frame along this, and one end is fitted into the corner of the fixed frame 2. One end of each of the links 11 and 11, which are pivotally supported inside the fixed frame 2, is attached to an engaging member 17 fixed to the inside thereof, with one end of each fixed to the inside of the fixed frame 2. Torsion bar 18.18
A bent arm 20 is engaged with the other end of each of the links 11, and the torsion force of each torsion bar 18 biases each link 11 in the direction in which it stands up.
is urged in a direction to move away from the fixed frame 2 above. In addition, the turning pulley 1 is the same as the turning pulley 16 supported at both corners of the fixed frame 2 at the base end of the one-car link 11, ll.
6 is also supported by support members 21 at both other corners of the fixed frame 2, and a total of four turning pulleys 22 corresponding to each of these four turning pulleys 16 are respectively supported by the support frame 3 of the window plate 6.

A wire rope 25, whose one end is connected to a bracket 24 fixed to the inside of the fixed frame 2, is successively strung between upper and lower corresponding turning pulleys 16, 22 at each corner of the fixed frame 2 and the supporting frame 3. The other end is connected to a drum 27 of a winding device 26 fixed inside the fixed frame 2.

The skylight of this embodiment has the above-mentioned configuration, and as shown in FIG. When the drum 27 is rotated and the wire rope 25 is wound up, each turning pulley 2 supported at the four corners of the support frame 3 of the window plate 6
Each link 10 of the plane parallel movement mechanism 8 is pulled downward by the wire rope 25 with equal force.
The slider 14 slides in the guide groove of the guide member 15 and tilts against the urging force of the torsion bar 18, whereby the window plate 6 is drawn toward the fixed frame 2. When the window is closed, and in the window closed state, the drum 27 is rotated in the opposite direction to the above by reversing the reversible motor 28 of the first winding device 26 to unwind the wire lobe 25, each link 10 of the plane parallel movement mechanism 8 11 swings in the direction of standing up due to the urging force of the torsion bar 12, the window plate 6 rises and is opened.In this embodiment, when the window plate 6 is raised and lowered, its support Since the four corners of the frame 3 are each pulled downward with equal force, the window plate 6 can be moved up and down stably without shaking.

In this embodiment, two of the four turning pulleys 16 supported at the four corners of the fixed frame 2 are connected by connecting the ends of the links 11 of the parallel movement mechanism 8 to the corners of the fixed frame 2. By supporting the base ends of these links 11 by the shafts 15, the wire ropes 25 routed along the fixed frame 2 by bending the turning pulleys 16 in the same direction are connected to the links 1.
