Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD This invention relates to a driving device for a shutter or blind.

Prior art shutters or blinds are usually suspended vertically, and when the shutter or blind is moved down and closed, its own weight is used to move it down, so that it can be closed with a small operating force. However, if these shutters are designed to be opened or closed in a direction other than the vertical direction, for example if a shutter is installed on a skylight, the shutter cannot be opened or closed using its own weight; Both tasks required a great deal of operating force.

OBJECTS It is an object of the present invention to overcome the drawbacks of the conventional shutter or blind driving devices as described above, and to provide a shutter or blind driving device that has a simple structure and is easy to operate.

EXAMPLE Below, an example embodying this invention is shown in FIGS. 1 and 2.
To explain according to the figure, 1 is a skylight provided in a house, and a shutter storage part 2 is provided on the negative side of the skylight. Reference numeral 3 denotes a winding shaft whose both ends are rotatably supported by the shutter storage section 2, and one end of the shutter 4, which is constructed by connecting a number of slats, is fixed. When the winding shaft 3 is rotated, the shutter 4 is opened or closed.

5 is a fixed shaft that passes through the winding shaft 3 and has both ends fixed to the shutter storage section; 6 is the fixed shaft 5 and the winding shaft 3;
A mainspring spring disposed between the winding shaft 3 and the winding shaft 3, the outer end of which is fixed to the inner circumferential surface of the winding shaft 3, and the inner end fixed to the outer circumferential surface of the fixed shaft 5. It is set to the □ side so as to give silent power in the direction of entry. Reference numeral 7 denotes a guide rail provided opposite to one layer of the skylight 1□1, and supports both side edges of the shutter 4.

Reference numeral 8 denotes a tape made of metal, cloth, etc., one end of which is fixed to the winding shaft 3, and is wound together with the shutter 4 as the winding shaft 3 rotates in the direction indicated by the arrow. ing. The other end of the tape 8 is fixed to a tape winding shaft 10 via a guide roller 9 supported by the shutter storage section 2, and the tape winding shaft 10 is rotated in the direction of arrow B by the operating handle H. When the tape 8 is wound together with the shutter 4, the tape 8 is rewound, the winding shaft 3 is rotated in the direction of arrow C, and the shutter 4 is extended along the guide rail.

Further, the tape winding shaft 10 is provided with a locking means (not shown) for preventing rotation in the direction indicated by the arrow. Rotation is prevented and the shutters 4 can be stopped at a desired overlapping position of 1, . . . . 11 is a guide for the shutter 4 and tape 8;

Next, the operation of the shutter configured in this way will be explained.

First, to close this shutter 4, the tape winding shaft 10 is rotated in the direction of arrow B against the elastic force of the mainspring spring 6. At the same time, the tape 8 is rewound and the winding shaft 3 is rotated in the direction of arrow C. direction, the shutter 4 is rotated in the direction of the guide rail 7.
is extended along the

Then, when the locking means is fully activated at the position where the skylight 1 is closed by the shutter 4 and the rotation of the tape winding 111110 in the direction of the arrow is prevented against the elastic force of the mainspring spring 6, the shutter 4 is moved to that position. can be stopped.

When the locking means is released from this state, the winding shaft 3 is rotated in the direction of the arrow by the elastic force of the mainspring spring 6, the shutter 4 is taken up by the winding lll1II3, and the skylight 1 is automatically opened. . At this time, the tape 8 is automatically wound together with the shutter 4.

Therefore, when closing the shutter 4, it is possible to extend the shutter 4 along the guide rail 7 by rotating the take-up shaft 10, and when opening the shutter 4, by releasing the operation of the locking means. Since the shutter 4 can be automatically wound up by the elastic force of the mainspring spring 6, its operation is easy.

In addition to the embodiments described above, the present invention can also be implemented in the following embodiments.

(a) In the above embodiment, the tape 8 was wound together with the shutter 4, but the tape 8 is wound around the winding M3 on both sides of the shutter 4.

(b) As shown in FIG. 6, the driving device of the above embodiment is fully applied to the shutter 4 which is installed in the vertical direction and opens and closes in the horizontal direction.

(c) Tape winding shall be driven by 1lflioi motor.

B) Applying the above embodiment to a normal shutter that opens and closes in the vertical direction. Also, apply to the driving device of blinds.

Effects As detailed above, this invention provides a spring means δ that applies rotational force in one direction to the winding shaft 3 such as the shutter 4,
A tape 8 is provided which is wound onto the take-up shaft 3 as the winding shaft 3 rotates, and the tape 8 is rewound to rotate the winding shaft 3 against the biasing force of the spring means 6. By providing the tape winding shaft 10, the shutter 4
Since either the opening or closing operation can be performed by the biasing force of the spring means 6, this invention is excellent as a drive device for a shutter or the like that has a simple structure and can be easily operated. .
