Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an apparatus for correcting the posture of a panel body in a panel shutter installed in an opening of a building.

[Problems to be solved by the prior art and the invention] Generally, in this type of panel shutter, a plurality of panel bodies are arranged in series within a shutter case facing the upper ends of guide rails provided on both the left and right sides of the opening. A drive sprocket that meshes with a connecting chain that is connected in a shape, and a storage rail that is moved laterally by a guide roller provided on the panel body as the drive sprocket winds up the chain, and the panel body is stored in a parallel manner. A so-called chain-linked panel shutter is known, in which the panel bodies are stored in parallel on the storage rail by the chain winding operation of the drive sprocket, and the chain winding operation of the drive sprocket is also known. The opening is closed by drawing out the panel body toward the guide rail by the lowering operation. However, in this case, the upper ends of both left and right sides of the panel body are connected to the connecting chain so that the lower end of the panel body is in a free state (swingable back and forth), so the panel body is moved from the storage rail by the drive of the drive sprocket. When being transferred to the guide rail side, the lower end of the panel body often swings significantly in the front and back direction due to rotation in the rotational direction by the drive sprocket, and this becomes more noticeable as the panel body is transferred at higher speeds. It was hot. In this case, the lower end of the panel body does not fit into the intake opening of the guide rail and gets caught, making it difficult for the panel shutter to open and close smoothly and causing breakage and damage.

[Means for solving the problem] The present invention was created in view of the above-mentioned circumstances with the aim of providing a posture correcting device for a panel body in a panel shutter that can eliminate these drawbacks. , each panel body,
While the lower end of the panel remains free, the upper ends of both left and right sides are connected in a series at a predetermined interval to a pair of left and right connecting chains, and the upper ends of the guide rails provided on both left and right sides of the opening Inside the facing shutter case, there is a drive sprocket that meshes with the connecting chain, and a panel body that is rolled up in the vertical direction by the forward rotation of the drive sprocket, and is guided in the horizontal direction to arrange a plurality of panel bodies in parallel. In a panel shutter provided with a storage rail for storing the panel body, the panel body is disposed in the shutter case so as to face the transport path of the panel body which changes from the horizontal direction to the vertical direction by reverse driving of the drive sprocket,
A panel posture in which the lower end of the panel body is inclined toward the storage rail side, and the panel body is brought into contact with the upper end portion of the chain connection position to correct the panel body toward the vertical position, and the lower end of the panel body faces the above-mentioned intake opening. This device is characterized in that a correction member is provided.

With this structure, even if the temporary panel body swings back and forth significantly when being transferred from the storage rail to the guide rail, the posture of the temporary panel body can be reliably corrected and smooth opening/closing operations can be performed at all times. It has been made possible.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawings, 1 is a panel shutter installed in an opening of a building, and a plurality of panel bodies 2 forming the panel shutter 1 are shown.
A connecting chain 4 is pivotally connected in a series at a predetermined interval to a support shaft 3a of a guide roller 3 which is protruded from the upper end of both left and right sides thereof. The guide roller 3 and both ends of the panel body 2 are guided by guide rails 5 provided on the left and right sides of the opening, so that they move up and down. drive sprocket 7 disposed within the starter case 6;
The connecting chain 4 is meshed with the connecting chain 4. Further, the shutter case 6 has a storage rail 8 that is appropriately inclined so that one end faces the upper side of the winding side of the drive sprocket 7 and the other end is lower than the one end.
It's decorated. And drive sprocket 7
By the chain hoisting operation, the guide rail 5
The guide roller 3 of the panel body 2, which has been raised,
The panel body 2 is carried around to the upper storage rail 8 side and conveyed onto the storage rail 8, and the guide roller 3 is conveyed onto the storage rail 8 in this way. storage rail 8
The shutters move laterally while rolling toward the other end, and are sequentially stored in parallel in the shutter case 6. On the other hand, a panel guide 9 is provided below the chain unwinding side of the drive sprocket 7, and guides the lower end of the panel body 2 unwound by the driving of the drive sprocket 7 to the guide rail 5. ing.

Reference numeral 10 denotes a protrusion provided at the left and right upper end portions of the panel body 2 so that the tips thereof protrude from above the panel body 2; and 11 a protrusion provided so as to face the drive sprocket 7 across the transfer path of the panel body 2. In the posture correcting member 11, the panel body 2 is carried downward from the storage rail 8 by the driving of the drive sprocket 7, and the lower end of the panel body 2 is placed in the panel guide 9. Therefore, when the panel body 2 is tilted by the driving of the drive sprocket 7 until it is guided to the guide rail 5 side, the protrusion 10 comes into contact with the panel body 2, so that the tilted panel body 2
The posture is corrected to the vertical side.

In the embodiment of the present invention configured as described above, the panel body 2 descends while being guided by the guide rail 5 and closes the opening by driving the drive sprocket 7 forward and backward to wind down and wind up the chain. Alternatively, it is laterally moved on the storage rail 8 and stored in the shutter case 6, and the opening is opened and closed in this way.

In such an opening/closing operation of the opening, when the panel body 2 moves from the shutter case 6 to the guide rail 5 side, the panel body 2 is tilted forward by the turning force of the drive sprocket 7. When the panel body 2 is tilted, the protrusion 10 provided on the panel body 2 comes into contact with the posture correction member 11 and the panel body 2
The posture will be corrected to a vertical posture. Therefore, even if the panel body 2 is tilted to such an extent that the lower end of the panel body comes off the temporary panel guide 9, the tilt is corrected by the posture correction member 11, and the lower end of the panel body 2 is reliably guided to the guide rail 5 side. Therefore, there is no problem such as the panel body 2 coming off from the panel guide 9 as in the conventional case. As a result, it is possible to reliably prevent problems such as the lower end of the panel body 2 not being swallowed by the guide rail 5 and getting caught, preventing smooth opening/closing operation, or breaking or damaging the panel body 2.

Moreover, since the posture correction of the panel body 2 by the posture correction member 11 is reliably performed even during high-speed transport where the tilt of the panel body 2 becomes noticeable, the opening/closing operation speed of the panel shutter can be greatly increased.

Furthermore, in this embodiment, since the protrusion 10 is located inside the face plate of the panel body 2, the posture correction member 11 can be brought close to the drive sprocket 7, which makes the shutter case 6 smaller and lighter. This is convenient because it can significantly contribute to the

It should be noted that the present invention is of course not limited to the above-mentioned embodiments. Also, the posture correction member 11 is not necessarily connected to the drive sprocket 7 across the transport path of the panel body 2.
It is not necessary to provide it at opposing positions, that is, at both left and right ends of the shutter case 6, but it may be provided at the center of the shutter case 6, etc.

[Operations and Effects] In summary, since the present invention is constructed as described above, the panel body whose lower end is in a free state is moved from the storage rail side to the guide rail side by the reverse drive of the drive sprocket. Even if the panel body is tilted forward due to rotation of the temporary drive sprocket during transportation, the panel body posture will remain unchanged.
When the upper end portion comes into contact with the posture correcting member, the posture is corrected to the vertical side, and the lower end of the panel body is reliably fitted into the intake opening at the upper end of the guide rail. Therefore, the panel body is reliably guided by the guide rail to close the opening, and as a result, the panel shutter can always be opened and closed smoothly, and the panel body is also prevented from being damaged or damaged. can be prevented.
Furthermore, the panel body posture is reliably corrected even during high-speed transport where the panel body tilts significantly.
The opening/closing speed of the panel shutter can be greatly increased.
