Description

[Detailed Description of the Invention] The present invention relates to the structure of an opening/closing mechanism for a skylight that can be opened and closed electrically.

Skylights are installed on the roofs of ordinary houses and various buildings for daylighting and ventilation, but conventionally, openable skylights have a door that closes the top opening of the skylight frame, and one end of the door is used as a pivot point to rotate upward. In the first two cases, the opening angle of the door was large, as the structure was such that the door could be pushed open upwards, the middle part of the door could be used as a rotational fulcrum and the door could be opened vertically, and the door could be slid onto the skylight frame. In the latter case, the skylight frame and the sliding part of the door were not sufficiently closed off from rain, making them susceptible to rain leaks.

The purpose of this invention is to eliminate the above-mentioned drawbacks by providing an openable skylight which is provided with a door that closes the top opening of the skylight frame, and which is attached to the skylight frame via a parallel link mechanism so that it can be opened and closed freely. This gives the door great support strength whether it is open or closed, and therefore not only can the door be opened sufficiently outwardly of the skylight frame to provide a large opening degree, but also employs an endless chain drive mechanism to ensure both opening and closing operations, and when the door is closed, the parallel link mechanism applies downward pressure on the door, thereby improving weather protection between the door and the skylight frame.

The structure of the present invention will be described with reference to the embodiment shown in the drawings. In FIGS. 1 and 2, 1 is a skylight frame, and the skylight frame 1 is fitted into the roof 2 of a building, Coating 3
is applied. 4 is its cover plate. The above-mentioned skylight frame 1 is in the form of a frame with openings at the top and bottom, and two left and right doors 6, 6 are provided on the skylight frame 1 to close the top opening 5, and these two doors 6 and 6 are respectively attached by a pair of front and rear parallel link mechanisms 7, 7 so as to be openable and closable from side to side. Each door 6 is made of a metal frame 8 covered with a transparent plate 9 made of glass or the like, and each parallel link mechanism 7 is composed of two link arms 10 and 11, of which the outer Link arm 11
is a right-angled bent arm so as to straddle the skylight frame 1 when the door 6 is opened. One end of each link arm 10, 11 is rotatably attached to the frame 8 of the door 6 by pivot pins 12, 13, and the other end is attached to the front and rear surfaces of the skylight frame 1 by pivot pins 14, 1.
5, it is rotatably pivoted. 16 is an electric opening/closing machine for the doors 6, 6, and the electric opening/closing machine 16
is installed on one side of the skylight frame 1 via a mounting base 17. An endless chain 20 is wound between the rotating sprocket 18 of the electric opening/closing machine 16 and the reversing sprocket 19 attached to the other end of the skylight frame 1. The lower side of the link arm 1 of the other door 6 is attached to the engaging part 21 of the intermediate part of the link arm 10.
It is pivotally supported at an engaging part 22 at the middle part of 1. Note that a switch (not shown) of the electric opening/closing machine 16 is arranged at a convenient position for operation. Packing is provided between the contact portions between the upper edge of the skylight frame 1 and the doors 6, 6.

Other embodiments of the present invention are shown in FIGS. 3 and 4, and FIGS. 5 and 6, respectively. In the former, the outer link arm 11' of each parallel link mechanism 7 is bent into a substantially arc shape so as to straddle the skylight frame 1 when the door 6 is opened. Moreover, the latter one is a parallel link mechanism 7
Both the inner and outer link arms 10a and 11a are composed of bent arms that straddle the skylight frame 1 when the door 6 is opened, and the inner link arm 10
a has a substantially right-angled shape, and the outer link arm 11a has one substantially right-angled side bent at a substantially right angle, and the degree of opening of the door 6 is increased in the order of each of the above embodiments. It is changing in the opposite direction. The other configurations of each of the embodiments shown in FIGS. 3 and 4, and 5 and 6 are the same as those of the embodiment shown in FIGS. 1 and 2. , electric switchgear, and others are omitted from illustration.

In the openable and closable skylight constructed as described above, in the embodiment shown in FIGS. 1 and 2, when the switch of the electric opening/closing machine 16 is operated to the "open" side, the rotating sprocket 18 is opened. rotates,
Since the chain 20 rotates in opposite directions on the upper and lower sides, the left and right link mechanisms 7, 7 connected thereto
The inner link arms 10, 10 rotate in opposite directions, and due to this pivoting, the doors 6, 6 are moved in parallel from side to side and opened. Since the outer link arm 11 of each parallel link mechanism 7 is bent so as to straddle the skylight frame 1,
The degree of opening of the doors 6, 6 can be increased. To close the doors 6, 6, operate the switch of the electric opening/closing machine 16 to the "close" side, the rotating sprocket 18 of the electric opening/closing machine 16 will rotate in the opposite direction, and the chain 20 will rotate in the opposite direction, so that the door 6 can be closed. , 6 move until they abut each other at the intermediate position between the left and right sides, and the upper opening 5 of the skylight frame 1 is completely closed by the doors 6, 6.

In the embodiment shown in FIGS. 3 and 4, the outer link arm 11' is also connected to the skylight frame 1.
Since the doors 6 and 6 are bent so as to straddle the
will be wide open. In addition, in the embodiment shown in FIGS. 5 and 6, each door 6 is fully opened by inverting the pair of front and rear parallel link mechanisms 7 using the pair of front and rear parallel link mechanisms 7 as pivot points. I can do it.

Incidentally, in any of the above embodiments, the doors 6, 6 are supported by a pair of front and rear parallel link mechanisms 7, 7, respectively, in either the open or closed state. High support strength. Therefore, even if the doors 6, 6 are opened sufficiently to the outside of the skylight frame 1, the doors 6, 6 are kept in a stable state, so that the degree of opening of the doors 6, 6 can be increased. Furthermore, when the doors 6, 6 are closed, a downward pressing force is generated by the pair of front and rear parallel link mechanisms 7, 7, respectively, so that rain protection between the doors 6, 6 and the skylight frame 1 is extremely good. .

In summary, the present invention provides a skylight opening/closing mechanism in which a door that closes the top opening of the skylight frame is attached to the skylight frame so as to be openable and closable via a parallel link mechanism including an operating link arm, and the opening/closing mechanism includes: The structure is such that an endless chain, which is driven reciprocally between the drive sprocket and the reversing sprocket by an electric opening/closing machine, is pivotally supported at the intermediate engagement part of the operating link arm, so the door can be opened and closed. Not only is the drive reliable in either direction, but the actuating force acts even when the door is closed, making it possible to prevent rain between the door and the skylight frame. In some cases, one opening/closing machine can be operated at the same time, which provides extremely useful practical effects.
