[Detailed explanation of the idea] [Industrial application field]

This invention relates to a shutter device that opens and closes shutter openings such as doors and windows.

[Conventional technology]

Conventionally, a pair of guide rails are placed on both sides of an opening for opening and closing a shutter such as a door or window, a plurality of upper and lower slats are connected vertically and are raised and lowered along the guide rails, and the slats are driven to be raised and lowered. Various shutter devices have been proposed, which are equipped with a slat elevating drive section that moves the slat up and down along a guide rail to open and close the opening.

[Problem that the idea aims to solve]

However, in the conventional shutter device of this type, when the opening for opening and closing the shutter is closed by the slat,
There was a problem in that it was not possible to provide sunlight or exchange air. This idea was made to solve the above problem, and when the shutter opening is closed by the slats, the slats can be mechanically connected vertically to each other. However, the object of the present invention is to provide a shutter device that allows lighting, air exchange, etc. to be easily performed in the closed state of the shutter.

[Means to solve the problem]

When the shutter is closed, the convex portions and concave portions of the slats are sequentially engaged vertically, and the opening/closing operation shafts are sequentially connected vertically, so that the slats are closed while the shutter is closed. After raising the above-mentioned convex portions and concave portions to a height at which they are separated,
By rotating each of the connected opening/closing operation shafts, each opening/closing frame support shaft is rotated via the gear, and each opening/closing frame is attached to each vertical frame and rotated. It is composed of

[Effect]

In the shutter device according to this invention, when the shutter is in a closed state in which each slat is lowered along the guide rail and the shutter opening/closing opening is closed, the upper and lower ends of each slat are vertically engaged by the convex portion and the concave portion. Therefore, the slats can be mechanically connected vertically to each other. Furthermore, with the shutter closed, after each slat is raised to the height where the protrusion and recess are removed, the opening/closing frame of each slat can be opened by simply rotating the opening/closing operation shaft connected vertically. A portion of each slat can be opened and closed by rotating the vertical frame.

【Example】

An embodiment of this invention will be described below with reference to the drawings. As shown in FIGS. 1 to 3, each slat 1 has a vertical frame 2 on both sides, a pair of opening/closing frame support shafts 3 rotatably attached to the vertical frame 2 horizontally, and a space between the vertical frame 2. It has an opening/closing frame 4 which is arranged at intervals and whose both sides are fixed to opening/closing frame support shafts 3. Vertical frame 2 above
An opening/closing operation shaft 5 for rotating the opening/closing frame support shaft 3 and opening/closing the opening/closing frame 4 is vertically mounted inside. A shaft 6 is provided protruding from the upper side surface of the vertical frame 2, and a roller 7 attached to the shaft 6 is guided along a pair of guide rails 8 installed vertically on both sides of an opening for opening and closing a shutter such as a door or window. It is engaged so that it can move up and down. When supported by the guide rail 8, the slats 1 are arranged continuously in the vertical direction so that the front surfaces thereof are flush with each other, and when stored inside the storage box 9 connected to the upper end of the guide rail 8, they can be folded mutually. They are folded and arranged vertically. Then, each slat 1 is inserted into the shaft 7 with a long hole 1.
They are connected to each other in a flexible manner by a connecting link 10 which is loosely fitted through the connecting link 10 and whose other end is rotatably supported by a shaft 11 on the side surface of the leading slat 1. Further, at the upper end of the opening/closing frame 4, a convex portion 4a is provided.
A recessed portion 4b is provided at the lower end, and both upper and lower ends of each slat 1 are provided with an uneven portion 4a, when the shutter is closed, which will be described later.
4b to prevent rattling even if wind, external force, etc. act on the slat 1.
The slats 1 are mechanically connected vertically to each other. The opening/closing operation shaft 5 has a screw gear 13 that meshes with the screw gear 12 of the opening/closing frame support shaft 3, and the lower end thereof is connected to the opening/closing operation shaft 5 of the succeeding slat 1 immediately before closing the shutter.
engages the upper end of the And the bottom slat 1
The lower end of the opening/closing operation shaft 5 engages with a drive section 14a attached to the lower end of a shutter opening/closing opening such as a window frame 14 and rotated manually or by power, and this rotational force is applied to the opening/closing operation of each slat 1. The signal is formed to be transmitted to the shaft 5. The upper end of the guide rail 8 located in the storage box 9 is connected to a support rail 8a extending substantially horizontally as shown in the third figure, and suspends and supports the slat 1 via a shaft 6 and rollers 7. 3
As shown in FIG. 4, a slat lifting/lowering drive section 15 is arranged. The slat elevating drive unit 15 includes a lower cam 16 that engages with the shaft 6 and rollers 7 of the slat 1 and rotates while guiding the slat 1 up and down, and a lower cam 16 that positions and guides the slat 1 that has moved up and down, and It has an upper cam 17 that is transferred in a state where it is prevented from falling. The lower cam 16 is disposed on the side wall of the storage box 9 via a rotating shaft 16a, and in this embodiment,
As shown in the fourth diagram, the rotating shaft 18a of the motor 18, the sprocket 19 → the chain 20 → the sprocket 2
1 → Shaft 22 → Gear 23 → Gear 24 → Gear 2
5→Connection link 26→It is formed to be driven in the direction of the arrow via the rotation shaft 16a. and,
The claw portion 16b of the lower cam 16 rotates within the movement path of the shaft 6 and roller 7 at the upper end of the slat 1 as shown in the third figure, and engages with the shaft 6 and roller 7 to raise and lower the slat 1. It is formed to provide transport guidance. The upper cam 17 is disposed above the lower cam 16 and on the side wall of the storage box 9 via a rotating shaft 17a, and is configured to rotate in the direction of the arrow in synchronization with the lower cam 16 by means of a connecting link 26. ing. As shown in the third diagram, this upper cam 17 is
It is formed into a disk shape having grooves (two in this embodiment) 17b for engaging the shaft 6 of the slat 1 and the roller 7. Then, the circumferential portion 17c of the upper cam 17 rotates while contacting the shaft 6 and roller 7 of both the preceding slat 1 and the succeeding slat 1, and the groove 17b also contacts the shaft 6 and roller 7 of the slat 1. When engaged, the slat 1 is transferred and guided. Therefore, each slat 1 is positioned and guided by the upper cam 17, and the two slats 1 are prevented from falling on the guide rail 8.
can be smoothly transferred from a vertical position to a horizontal position and vice versa. Next, the operation of this guidance will be explained. First, the raising and lowering operation of the slat 1 is performed as follows. The slat 1 is pushed up by the shaft 6 attached to the vertical frame 2 of the slat 1 and the lower cam 16 that engages with the roller 7, and rises along the guide rail 8. At this point, the shaft 6 of the slat 1 is pushed up to point B in FIG. 3, and at the same time the groove 17 of the upper cam 17
The shaft 6 etc. are scooped up at b and transported to point A. Note that the above-mentioned point B is located at the contact point between the upper cam 17 and the lower cam 16. Further, when the shaft 6 etc. of the slat 1 is transferred from point B to point C, the shaft 6 etc. of the subsequent slat 1 is located at point D and abuts and engages with the claw portion 16b of the lower cam 16. It becomes the starting point. In this operation, the succeeding slat 1 is connected to the guide rail 8.
This process is repeated every time the upper cam 17 reaches the vicinity of the substantially horizontal part 8a, and the two slats 1 are positioned by one rotation of the upper cam 17, and are smoothly transferred to the substantially horizontal part of the guide rail 8 while preventing the two slats from falling. Conversely, when the slat 1 is extended, the upper and lower cams 1
This is done by rotating the slats 7 and 16 in opposite directions, and the groove 17b of the upper cam 17 that engages with the shaft 6 of the slat 1 ensures that the slats 1 are fed out one by one. As mentioned above, dropping two sheets etc. is reliably prevented. Next, the slat 1 which is the biggest feature of this invention.
The opening/closing operation of the opening/closing frame 4, which is a part of the opening/closing frame 4, is performed immediately before closing the shutter. That is, just before closing, the opening/closing operation shaft 5 of the lowermost slat 1 engages with the drive part 14a attached to the window frame 14, etc., and the opening/closing operation shaft 5 of each slat 1 also engages from above and below, respectively. The rotational force of the drive unit 14a is transmitted to each opening/closing operation shaft 5. By the rotation of this opening/closing operation shaft 5, the screw gear 1
2 and 13, the opening/closing frame support shaft 3 is rotated to the left or right, and the opening/closing frame 4 is rotated relative to the vertical frame 2 around the opening/closing frame support shaft 3 to be opened and closed as shown in the second figure. Then, with the opening/closing frame 4 once closed, the slat 1 is completely lowered until the lowest slat 1 is installed at the lower end of the window frame, etc., and when the shutter is closed, both upper and lower ends of each slat 1 The convex portion 4a and the concave portion 4b are engaged from above and below, and each slat 1
They can be mechanically connected vertically. Therefore, in the closed state of the shutter, even if wind, external force, etc. act on each slat 1, it is difficult for each slat 1 to rattle, and there is no gap between each slat 1, so rain, wind, etc. etc. will not invade. Note that when each opening/closing frame 4 is closed, each slat 1
is lowered to bring the shutter into a closed state. After that, each slat 1 is raised to a height at which each protrusion 4a and recess 4b are removed, and each opening/closing operation shaft 5 connected vertically is rotated. Thus, each opening/closing frame 4 can be opened and closed by rotating around each opening/closing frame support shaft 3.

[Effect of the idea]

As described above, according to this invention, when the shutter is in the closed state where each slat is lowered along the guide rail and the shutter opening/closing opening is closed, both the upper and lower ends of each slat are moved upward and downward by the convex portion and the concave portion. Since the slats are engaged with each other and the slats can be mechanically connected vertically, even if wind, external force, etc. act on the slats when the shutter is closed,
In addition to the slats being less likely to rattle, there are no gaps between the slats, so rain, wind, etc. do not enter at all, and the opening for opening and closing the shutter can be completely sealed. However, with the shutter closed, after each slat is raised to the height where the protrusion and recess are removed, the opening/closing frame of each slat can be opened by simply rotating the opening/closing operation shaft connected vertically. Since a portion of each slat can be opened and closed by rotating the vertical frame, it has the advantage of being able to easily let in light and exchange air while the shutter is closed.
