Description

[Detailed Description of the Invention] This invention relates to a slat opening/closing mechanism for a panel type shutter device that can open and close a part of the slat while the slat is closed.

Hitherto, shutter devices have been proposed that allow lighting and air exchange with the slats closed, as seen in, for example, Japanese Utility Model Application No. 49-14740 and Japanese Patent Application Laid-open No. 49-113443. However, the structure of opening and closing a part of the slat for daylighting, etc., all had drawbacks such as being complex and requiring a large number of parts.

This invention solves the above-mentioned drawbacks, and relates to a slat opening/closing mechanism for a panel type shutter device, which allows only a part of the slat to be opened and closed like a blind when the slat is closed, and allows lighting, air exchange, etc. to be easily performed with a simple structure.

An embodiment of this invention will be described below with reference to the drawings.

Each slat 1 includes a pair of vertical frames 2 extending vertically as shown in FIGS. 1 to 3, and an opening/closing frame support shaft 3 rotatably installed at a predetermined position of each vertical frame 2. It is located between a pair of vertical frames 2, and is fixedly supported on both sides by the opening/closing frame support shaft 3.
There is a plate-shaped opening/closing frame 4 that is rotatable with respect to the vertical frame 2, and a plate-shaped opening/closing frame 4 that is rotatable along and around the vertical frame 2, and when the slat 1 is closed, the tip of the slat 1 is a rotation transmission shaft 5 that is connected to the upper end of the rotation transmission shaft 5 of the lower adjacent slat 1 and sequentially transmits rotational force;
A gear (first transmission member) 7 and a gear 6 (first transmission member) are provided on the rotation transmission shaft 5 and the opening/closing support shaft 3, respectively, and transmit rotational force therebetween by engaging with each other. 2 transmission member).

When the lowermost slat 1 is closed, the lower end of the rotation transmission shaft 5 engages with a drive section 8a attached to the window frame 8 or the like and rotated manually or by power, and this rotational force is transmitted to each It is formed so as to transmit the rotation to the rotation transmission shaft 5 of the slat 1.

Further, a shaft 9 is protruded from the upper side surface of the vertical frame 2, and a roller 10 attached to the shaft 9 is engaged so as to be movable up and down along guide rails 11 installed on both sides of an opening in a building, etc. There is. When supported by this guide rail 11, each slat 1 is arranged continuously in the vertical direction so that its front surface is on the same plane.
Storage box 1 connected to the upper end of guide rail 11
When housed inside 2, they are arranged in a mutually folded and erected state. And each slat 1 is
One end is loosely fitted to the shaft 9 through the elongated hole 13a,
They are connected to each other in a flexible manner by a connecting link 13 whose other end is rotatably supported by a shaft 14 on the side surface of the slat 1 leading the other end.

The upper end of the guide rail 11 located inside the storage box 12 is connected to a support rail 11a extending in a substantially horizontal direction, suspends and supports the slat 1 via rollers 10, and is bent substantially horizontally as shown in the fourth figure. A roller locking piece 15 is arranged near the slat 1 to prevent the slat 1 from being inadvertently lowered. Although the number of roller locking pieces 15 to be installed is not limited in any way, the protrusion 15a is inserted into the movement of the roller 10, and the slat drive unit 16, which will be described later,
Passage of the roller 10 is permitted only when the slat 1 moves up and down.

The slat drive unit 16 is disposed inside the storage box 12, and includes a gear 17 rotated by a drive source (not shown) as shown in the third diagram, and a first cam 18 rotated by the gear 17. , and a second cam 20 which is rotated by transmitting the rotation of the first cam 18 via a connecting rod 19, and these first and second cams 18, 20 have a pair of protrusions ( Roller moving pieces) 18a and 20a are provided, and when the slat is raised and lowered, the protrusions 18
The positions of the protrusions 18a and 20a of both cams 18 and 20 are shifted so that the roller 10 can be moved up and down and horizontally by the cams 18a and 20a.

Next, the operation of this invention will be explained.

The action of storing each slat 1 in the storage box 12 is performed by clockwise rotation of the gear 17 of the slat drive section 16. As a result, the first and second cams 18, 20 also rotate clockwise, and the protrusions 18a, 20a of both cams 18, 20 move the rollers 10 of the slat 1 on the guide rail 11 and support rail 11a upward and horizontally, respectively. moving, especially the support rail 11a
The upper roller 10 is moved over the roller locking piece 15 by the protrusion 20a of the second cam 20 and is moved horizontally to the right. Therefore, the slat 1 is connected to the roller locking piece 15.
This effectively prevents accidental descent. Here, the succeeding slat 1 rises and the support rail 11a
When reaching the vicinity of the substantially horizontal bent portion 11b, which is the connecting portion of Moving. This operation is repeated every time the succeeding slat 1 reaches a position near the approximately horizontal bending part, and the first and second cams 18, 2
0, each slat 1 is successively suspended and supported from the support rail 11a via the roller 10.

On the other hand, each slat 1 is moved out by rotating the gear 17 counterclockwise. As a result, the first and second cams 18 and 20 are also rotated to the left, and the roller 10 of the slat 1 is rotated to the protrusion 18a, as described above.
20a, each slat 1 is sequentially moved in the drawing direction.

The opening/closing operation of the opening/closing frame 4, which is a part of the slat 1, which is the gist of this invention, is performed when the slat 1 is closed. That is, when the lowermost slat 1 is closed, the lower end of the rotation transmission shaft 5 of the slat 1 engages with the drive portion 8a attached to the window frame 8 or the like.
Thereafter, when each slat 1 reaches the closing position one after another, each rotation transmission shaft 5 is quickly connected one after another.
The rotational force of the drive unit 8a is sequentially transmitted to the rotation transmission shaft 5. Therefore, by the rotation of the rotation transmission shaft 5, the opening/closing frame support shaft 3 is rotated to the left or right via the gears 7, 6, and as a result, the opening/closing frame 4 is opened and closed as shown in the second figure. Even when the slat 1 is closed, light and air can be exchanged like a blind.

As described above, since the opening/closing frame is opened and closed by the rotation transmission shaft that is sequentially connected when the slat is closed, the simple structure allows a part of the slat to be easily opened and closed when the slat is closed. It has excellent effects such as easy lighting and air exchange.
