Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.

Figures 1 to 3 show a first embodiment in which the present invention is applied to a skylight, which includes a rectangular window frame 2 fixed to a horizontal roof surface (not shown) of a building, and a horizontal shoji screen that is also rectangular. 3, four X-link mechanisms 4 are installed in which two links 5 and 6 are connected by a shaft 7 at the central position in the length direction, and two of the four X-links Mechanisms 4a, 4a are arranged for driving at one end of the long sides 2a of the two window frames and the long side 3a of the shoji 3, and the other two X-link mechanisms 4b, 4b are for driving. They are arranged at the other ends of both long sides 2a, 3a in correspondence with each other.

One link 5 of each X-link mechanism 4 is tilted in the same direction, and a slider (not shown) supported by a shaft 8 at its upper end slides on a sliding guide 10 horizontally fixed to the shoji 3. Of these four links 5, two links 5a, 5a of the X-link mechanism 4a, 4a on the driving side are fixed to the window frame 2. Device 1

The lower ends of the two links 5b, 5b of the driven-side X-link mechanisms 4b, 4b are rotatably supported on the window frame 2 by the support shaft 11, and the lower ends of the two links 5b, 5b of the driven side The four links 6 each have an upper end rotatably supported by a support end 12 on the shoji 3, and a slider 18 supported by a shaft 17 at the lower end, respectively, on the window frame 2. The lower ends of the four other links 6 are fitted into the sliding guides 13 on the same long side 2a of the window frame 2, and are fitted in the sliding guides 13 fixed horizontally so as to be freely slidable. An elongated connecting link 16 parallel to the long side 2a is spanned between the parts, and both ends thereof are connected by shafts 17, 17 that support the slider 18, and by this connecting link 16, On each long side 2a of the window frame 2, a link 6a on the driving side and a link 6b on the driven side are integrally connected, and the shoji 3 is moved by the four X-link mechanisms 4 arranged at the four corners of the window. It is stably supported in a horizontal position.

A reversible motor 20 is fixed to one of the swing drive devices 15, 15 described above, and the swing drive devices 15a with the reversible motor are mounted parallel to each other as shown in FIGS. 2 and 3. A drive shaft 23 is formed by integrally forming an eccentric shaft portion 24 with a large diameter at the end of a substrate 21 and a support plate 22 fixed at a distance.
The eccentric shaft portion 24 is inserted into the through hole 25 of the support plate 22 so as to rotate freely, and the eccentric shaft portion 24 is fitted into the gap between the substrate 21 and the support plate 22. 26 is fitted into the bearing hole 27 of the base plate 21 so that it can rotate freely and cannot be removed in the axial direction. This internal gear 30 has one link 5a which has one to several fewer teeth than the internal gear 30 and which becomes the above-mentioned swing arm and is integrally molded to protrude in the radial direction. The external gear 31 fits concentrically and freely rotatably into the eccentric shaft portion 24 of the drive shaft 23 through its center hole 33 with its link 5a protruding from the gap between the base plate 21 and the support plate 22. The structure is such that the reversible motor 20 is fixed to a mounting plate 35 that is meshed with each other and supported parallel to the support plate 22, and when the reversible motor 20 is driven, a small-diameter gear 37 fixed to its output shaft 36 and The reversible motor 20 is engaged with a large diameter gear 39 that is connected to the drive shaft 23 and is fixed to a serration shaft portion 38 that protrudes between the support plate 22 and the mounting plate 35.
The rotational force of the output shaft 36 is decelerated and transmitted to the drive shaft 23. And drive shaft 2
3 rotates clockwise in Fig. 2, the eccentric shaft portion 2
4 revolves around the axis O of the drive shaft 23 in the same direction, the external gear 31 rotates around the internal gear 3
0, the drive shaft 23 rotates clockwise at a small radius around the axis O of the drive shaft 23 and rotates counterclockwise around the axis P of the eccentric shaft part 24, thereby causing the external gear Link 5a protruded into 31
However, when the drive shaft 23 is rotated counterclockwise in the figure, it is further decelerated and swings while tilting counterclockwise with the drive shaft 23 as the center. The link 5a is configured to swing while standing up in a clockwise direction, and
When the rotation of the drive shaft 23 stops, the meshing of the external gear 31 and the internal gear 30 stops the revolution and rotation of the external gear 31, and an external force acts on the link 5a to make it swing. It is designed so that it will be locked at the stop position without swinging even if it is moved.

Moreover, this swing drive device 15a with a reversible motor
The other swing drive device 15b corresponding to the reversible motor 20
It has a structure in which a mechanism for transmitting the rotational force to the drive shaft 23 is removed, and when the drive shaft 23 rotates, the link 5a swings by the same action as above, and this swing drive Device 15b
and the drive shaft 2 of the swing drive device 15a with a reversible motor.
3 and 23 are connected to each other by fitting hexagonal shaft portions 43, 43 formed on the respective end faces to protrude toward the other side into hexagonal holes 46, 46 recessed on both end faces of the connecting rod 45. The rotational drive of the reversible motor 20 causes the drive shafts 23, 23 of both swing drive devices 15a, 15b to rotate together, and both links 5a,
5a are arranged to swing parallel to each other at the same inclination angle.

The first embodiment has the above configuration, and when opening the window, the swing drive devices 15a, 15b are driven by the operation of a control device (not shown), and one link of the X link mechanisms 4a, 4a on the drive side is moved. When the links 5a, 5a are swung in the upright direction, the sliders (not shown) at their upper ends slide along the swing guides 10, 10 of the shoji 3, and the other links 6a, 6a are moved at their lower ends. The lower end of the link 6b on the driven side, which swings in the upright direction while sliding the sliders 18, 18 along the sliding guides 13, 13 of the window frame 2, is integrally connected by the connecting link 16. The slider 18 of
In the same direction as the slider 18 of the drive side link 6a,
Moreover, by sliding at the same speed, both links 5b and 6b of the X-link mechanism 4b on the driven side swing in the upright direction at the same inclination angle as the links 5a and 6a on the driving side, and the shoji 3 The window is opened by rising vertically while maintaining a horizontal position, and when the drive of the reversible motor 20 is stopped while the window is open, the internal gear 30 and external gear 31 of the swing drive device 15 mesh with each other. Since the link 5a is prevented from swinging, the drive-side X-link mechanism 4a is locked so that it cannot swing, and the driven drive, which is integrally connected to the locked drive-side X-link mechanism 4a by the connecting link 16, is locked. The X-link mechanism 4b on the side is also locked so that it cannot move, and the shoji 3 remains in a horizontal position at any opening degree without tilting in the length direction of its long side 3a or rattling due to the wind. Retained.

Furthermore, when closing the window, by driving the reversible motor 20 in the reverse direction, the shoji 3 is lowered and the opening of the window frame 2 is closed by operating in the opposite manner to the above. When the drive of the reversible motor 20 is stopped, the internal gear 30 of the swing drive device 15
The operation of both X-link mechanisms 4a, 4b is locked by the meshing between the shoji 3 and the external gear 31, so that the shoji 3 is locked in the closed state without using a locking device.

In the first embodiment, the swing drive device 15
The internal gear 30 is fixed to the substrate 21 and the link 5a is formed on the external gear 31. However, in contrast to this, the external gear 31 is fixed to the substrate 21.
1, and the link 5a may be formed on the internal gear 30.

Next, another embodiment of the present invention will be described.

Figure 4 shows the second example of a parallel projection window.
In this embodiment, vertical frames 52a, 52a of a vertically long rectangular window frame 52 fixed to a wall are provided, and vertical frames 53a, 53a of a rectangular shoji screen 53 are provided between the vertical frames 52a, 52a.
A pair of X link mechanisms 54a, 5a on the driving side and a pair of X link mechanisms 54b, 54b on the driven side are
The links 5 of the X-link mechanism 54a on the driving side are attached in a corresponding manner in the left and right directions.
6a and the link 56 of the driven X link mechanism 54b
The sliding ends of the links 59, 59b, fitted into the sliding guides 63, 63 fixed to the window frame 52, are connected together by a vertically long and thin connecting link 66, and furthermore, between the upper frame 52b of the window frame 52 and the upper frame 53b of the shoji screen 53, an X-link mechanism 58 for vibration prevention is attached by having one end of each of the links 59, 59 journaled on the window frame 52 and the shoji screen 53 and the other end fitted into the sliding guides 57, 57 fixed to the window frame 52 and the shoji screen 53. When the swing drive device 60 connected to the driving X-link mechanism 54a is driven, both X-link mechanisms 59, 59 swing outward.
The link mechanisms 54a and 54b work together to allow the screen 53 to protrude horizontally in a vertical position toward the outside to open the window, and to be pulled back toward the inside to close the window. When opening and closing the screen, the anti-vibration X-link mechanism 58 is used.
The screen 53 is prevented from moving freely in the lengthwise direction of its upper frame 53b or from swinging around a vertical axis.

What is shown in FIGS. 5 to 7 is a shoji 73 hinged to the upper frame 72a of a horizontally long rectangular window frame 72.
The third method is applied to a projecting window which is opened and closed by swinging around its upper stile 73a.
In this embodiment, the lower frame 72b of the window frame 72 and the shoji 7
A drive-side X-link mechanism 74a and a driven-side X-link mechanism 74b are installed with an interval left and right between the lower stile 73b of
The link mechanisms 74a and 74b are connected to the lower frame 72 of the window frame 72.
The link 75a is integrally connected by a connecting link 86 parallel to b, and also serves as a swinging arm of a swinging drive device 85 of the X-link mechanism 74a on the drive side.
, a short arm portion 77 protruding from the swing drive device 85 and a long arm portion 7 connected to the shoji 73.
8, and both arm parts 77 and 78 are
As shown in FIGS. 6 and 7, a connecting ring in which a spherical head 86 of a connecting pin 84 erected at the tip of a short arm 77 is fitted into a base end of a long arm 78. Stoppers 80 are connected via a ball joint 89 fitted into a spherical recess 88 of 87, and protrude from both side edges of the short arm portion 77.
By sandwiching the long arm portion 78, the link 75a is prevented from bending in the substantially horizontal direction, and the ball joint 79 allows the link 75a to bend at a small angle in the vertical direction. Furthermore, the end portions of the other three links 75b, 76, and 76 that are pivotally supported by the window frame 72 or fitted into the sliding guide 83 of the window frame 72 are connected to the window frame 72. This allows both X-link mechanisms 74a and 74b to swing vertically at a small angle with respect to the horizontal plane as the slope of the shoji 73 increases during window opening. Even if the window frame 72 or the shoji 73 is tilted, the connecting part to the window frame 72 or the shoji 73 will not be twisted and will operate smoothly.

In addition, in each of the above embodiments, a link mechanism in which two links are pivoted in an X-shape is used, but the present invention is not limited to this. Either use a lambda-shaped link mechanism that is pivoted at the center of the long link and use the short link as the swinging arm of the window frame swing drive device, or alternatively, use the short link as the swing arm of the window frame swing drive device, or use the short link that is pivoted directly to the window frame and connect one end of the long link. It can also be applied to a structure in which the frame is pivoted on a shoji screen and the other end is fitted into a sliding guide of a window frame.
