〔Example〕

Hereinafter, embodiments of the shutter device of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view schematically showing an example of a shutter device of the present invention. The shutter device 1 includes a rectangular frame member 2 attached to the outside of a building opening, and an upper portion of the frame member 2. Horizontally arranged elongated cylindrical upper screw guide 4
An elongated cam member 7 disposed inside the upper screw guide 4, a slender cylindrical lower screw guide 9 horizontally disposed in the lower portion of the frame member 2, the upper screw guide 4 and the lower portion. It is constituted by a large number of elongated shutter door members 3 supported between the screw guides 9.

As shown in FIG. 2, the upper screw guide 4 has a dense spiral pitch guide portion 5a formed at a predetermined interval at the left end of the drawing, and the right end after the dense spiral pitch guide portion 5a. The guide portions 5b having a coarse spiral pitch are formed at predetermined intervals in the direction.

These guide portions 5a, 5b are formed by penetrating the peripheral wall of the upper screw guide 4, and at the center of both ends of the upper screw guide 4, tubular rotating shafts 6a, 6b are formed.
b is attached integrally.

As shown in FIGS. 3 and 4, the cam member 7 is a tubular body having a substantially elliptical cross section, and an eccentric shaft 8 is provided at both ends thereof.
a, 8b are fixed, and the eccentric shafts 8a, 8b are arranged inside the upper screw guide 4 by penetrating the rotating shafts 6a, 6b of the upper screw guide 4, and the rotating shaft 6a is The eccentric shaft 8a that penetrates is configured to rotate separately from the upper screw guide 4 by a motor 14 via a gear mechanism, and its peripheral wall is rotated inside the upper screw guide 4 by this rotation. It is designed to swing.

As shown in FIG. 5, the lower screw guide 9 has a dense spiral pitch guide portion 10a formed at a predetermined interval at the left end portion of the drawing, and continues to the dense spiral pitch guide portion 10a, followed by a right end direction. A guide portion 10b having a rough spiral pitch is formed at a predetermined interval, and each guide portion 10a, 10 is provided with a spiral groove without penetrating the peripheral wall of the lower screw guide 9. The upper end of the upper screw guide 4 is supported by the rotating shaft, as in the upper screw guide 4.

However, the rotary shaft 6a of the upper screw guide 4 is connected to the gears 12a and 12b attached to the rotary shaft of the lower screw guide 9 via gears 11a and 11b as shown in FIG. 1, and via the gear mechanism. The upper and lower screw guides 4, 9 are synchronously rotated by the arranged motor 13.

As shown in Figs. 6 and 7, the shutter member 3 has a constant width of 10 to 15 cm and a constant thickness of 10 to 20 mm, and has a vertically long cross section that can be adapted to the vertical length of the building opening. It is formed of a parallelogrammatic steel plate hollow plate, and the upper pin 15 is placed at the center of the upper end.
However, a lower pin 21 is integrally attached to the center of the lower end.

The upper pin 15 is a cap member 16 on the upper part of the shutter member 3.
It is inserted into the guide tube 17 provided at the upper part of the upper pin 15 and is constantly urged upward by the spring 18 externally fitted to the upper pin 15 to project.

Then, in the inside of the guide pipe 17, a spiral guide groove 19 is formed.
Since the pin 20 fixed to the peripheral wall of the upper pin 15 is formed so as to engage with the guide groove 19, when the upper pin 15 is pushed downward against the spring 18, The member 3 is configured to rotate about the upper pin 15.

On the other hand, the lower pin 21 is a cap member at the lower end of the shutter member 3.
It is integrally fixed to 22 and does not have the structure like the upper pin 15.

Such a shutter door member 3 has a plurality of ventilation holes 23 vertically formed at intervals on the front surface and the back surface thereof, and has a plurality of ventilation holes (not shown) corresponding to the ventilation holes 23. ，
A slide plate 24 having an insect repellent net 25 attached to the ventilation holes is attached to the inside of the shutter door member 3 on the front side.

Therefore, by moving the knob 26 connected to the slide plate 24 up and down along the long hole 27 formed on the back side of the shutter member 3, the ventilation hole 23 and the ventilation hole of the slide plate 24 are made to coincide with each other and insect repellent. The inside and outside of the room can be ventilated, and the vent hole 23 on the front side can be closed by operating the knob 26 as necessary to make them inconsistent.

In the shutter door member 3 having such a structure, the upper pin 15 penetrates through the guide portions 5a and 5b of the upper screw guide 4 and the spring inserted outside the upper pin 15 is attached to the peripheral wall of the cam member 7 arranged inside. The lower pin 21 is supported by being contacted with it in a state of being appropriately pressed by 18, and the lower pin 21 is rotatably supported by engaging with the guide portions 10a, 10b formed by the spiral groove of the lower screw guide 9.

The shutter device 1 of the present invention having the above structure is fixed by the frame member 2 from the outside of the opening of the building.

At that time, the drive mechanism of the upper and lower screw guides 4 and 9 and the parts of the dense spiral pitch guide parts 5a and 10a provided on the screw guides 4 and 9 should be located outside the building opening and on the outer wall. It is attached, and it is desirable to cover this part with a panel from the outside.

The shutter device 1 is operated and opened / closed as follows.

First, when opening the shutter, the upper and lower screw guides
The motor 13 for driving 4, 9 is rotated in the opening direction, and the rotation is transmitted to the gears 11a, 11b and 12a, 12b to rotate the upper screw guide 4 and the lower screw guide 9 in the same direction in synchronization. Let

When the upper and lower screw guides 4 and 9 rotate in the same direction, the shutter member 3 supported by the upper and lower screw guides 4 and 9 is laterally moved along the guide portions 5a, 5b, 10a and 10b (see FIG. 1). To the left).

At that time, in the densely pitched guide portions 5a and 10a,
The shutter members 3, 3, 3, ... Align their respective thickness portions in a superimposed manner and the motor 13 automatically stops when the shutter members 3 are completely aligned.

Thus, the dense guide portions 5a and 10a for overlapping and aligning the shutter members 3, 3, 3 ... are equivalent to the door pocket of the conventional shutter, and the building openings are formed by this overlapping alignment. It can be opened.

Next, the case of closing the shutter device will be explained.
From this state, the motor 13 is rotated in the reverse direction, and the shutter members 3 aligned in a superposed manner by the guide portions 5a, 10a having the dense spiral pitch.
Are sequentially fed out from those close to the guide portions 5b, 10b having a rough spiral pitch, and are arranged at constant intervals at the guide portions 5b, 10b having a rough spiral pitch.

At this time, each shutter door member 3,3,3 ... is in a state in which its plate-like plate surfaces face each other at regular intervals, that is, the plate surface of the shutter door member 3 is opposed to the opening of the building opening. The motors 13 are automatically stopped by arranging them at regular intervals in a state of being at right angles.

After the completion of the feeding operation of the shutter members 3, 3, 3, ..., When the motor 14 is turned on and rotated, the cam member 7 arranged inside the upper screw guide 4 starts to rotate, and The swinging movement of the cam member 7 pushes the upper pin 15 of each shutter door member 3 downward.

Therefore, the pin 20 attached to the upper pin 15 is inserted into the spiral guide groove 19 formed in the pipe of the guide pipe 17 and descends along the guide groove 19, so that the urging force of the spring 18 is applied. On the contrary, the upper pin 15 is pushed down, and at the same time, the shutter member 3 itself rotates about the upper pin 15 and the lower pin 21.

When the upper pin 15 is pressed by the tip of the elliptical major axis of the cam member 7, the shutter member 3 is set so as to rotate at an angle of 90 °. In the shutter door members 3, 3, 3, ..., Adjacent side edges in the longitudinal direction contact each other to completely close the opening of the building, and the motor 14 automatically stops.

At this time, since each shutter door member 3 is formed such that the side edges in the longitudinal direction incline relative to the plate surface, the inclined side edges come into contact with each other and all shutter door members 3,3,3. ...
With this, the building opening can be surely fully closed in a flat state.

To fully open the building opening from this fully closed state, use the motor 14
Drive the cam member 7 to rotate the shutter members 3,3.
..The plate surface of is parallel to the glass door vertically.
After that, the motor 13 is driven and each shutter door member 3,3 ...
The motor 14 is moved to the left along the guide portions 5b and 10b having a coarse pitch, and is retracted into the guide portions 5a and 10a having a fine pitch. The motor 14 automatically stops at the fully closed position. Except for the above, the switch continues to rotate, and if the switch is released, it stops at that position. Therefore, if the switch is released midway, the motor stops rotating, and each shutter door member 3 , 3,3 ...
Since it is possible to stop at an arbitrary angle and maintain a state in which an appropriate gap is formed between each shutter door member, the shutter door member can serve as a blind for shading and ventilation.

Furthermore, the shutter door member is fully closed, and the knob 26 is operated to align the ventilation hole with the insect net of the slide plate 24 having the ventilation hole with the ventilation hole 23 formed in the shutter member 3 to prevent insect damage.ゝ Ventilation is possible, and this ventilation hole can serve as an appropriate light source.

Each motor 13, 14 has a function to stop when an abnormal load is applied, and a manual switching function in consideration of the case where the motor does not operate due to power failure or other reasons. It is preferable to add it.

In order to smoothly align and move the shutter member 3, an auxiliary aligning mechanism (not shown) by a link mechanism may be added to the upper and lower ends of the shutter member.

〔The invention's effect〕

The shutter device according to the present invention includes a frame member attached to the outside of a building opening, an upper screw guide disposed above the frame member, and a rotary member disposed inside the upper screw guide and separately from the upper screw guide. And a lower screw guide disposed below the frame member, a plurality of independent shutter door members supported between the upper and lower screw guides, and a drive mechanism for driving the upper and lower screw guides and the cam member. The shutter can be opened and closed easily from the inside of the building without opening and closing the glass door or the like.

In addition, by moving a large number of shutter door members independently and rotating them by the action of the cam member, a dark image such as a conventional shutter door is broken and a function equivalent to a blind or a louver is retained. Even from the fully closed state, uniform ventilation, daylighting, and light shielding can be easily performed.

Moreover, the double structure of the shutter member has a great practical advantage in that it can be expected to have excellent effects on heat insulation, soundproofing, and crime prevention.
