Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel guide and guide device in a panel shutter, and more specifically, during the opening / closing operation of the shutter, the upward movement of the panel to the horizontal movement during the opening process of the shutter. When the direction of the panel is changed, and during the closing process of the shutter, the front-back movement of the panel that occurs when the direction of the panel is changed from the horizontal movement to the downward movement is reliably prevented, and the lower end of the panel is horizontally aligned with the upper end. The present invention relates to a panel guide guide device for a panel shutter, which allows smooth and reliable movement of each panel smoothly and reliably even when the shutter is opened and closed at high speed by following the movement and the descending movement without delay. .

[Prior Art] Conventionally, in this type of panel shutter, a roller chain is attached to the roller shafts fitted in both ends of the upper frame of the panel to connect the panels in the vertical direction and guide the mesh with the roller chain. By rotating the sprocket forward and backward, each panel can be transformed so that it can move up and down along the guide rails and in the horizontal storage posture along the storage rails to open and close the shutter. When the shutter is opened, the lower end of the panel is unable to follow the horizontal movement of the upper end and swings in the front-rear direction when the panel is changed from the vertical position to the horizontal storage position. Blocking the ascending path and causing mutual collision of panels,
There is a danger that smooth opening operation will not be possible, and similarly when the shutter is closed when each panel is changed from the horizontal storage posture to the vertical posture, the lower end of the panel cannot follow the downward movement of the upper end and In many cases, the panel does not descend to the proper position in the guide guide at the upper end of the guide rail due to swinging in the direction, and this has a drawback that it hinders the opening / closing operation.

And, especially when the shutter is opened and closed at a high speed, the above-mentioned drawback becomes more remarkable, and it has a serious safety problem.

[Problems to be Solved by the Invention] The present invention has been devised in order to solve the conventional drawbacks in view of the above circumstances, and the object thereof is to:
A panel guide rail is provided in the lower area of the storage rail for restricting the deflection of the lower end of the panel in the front-rear direction, and the panel guide rail is aligned along the continuous locus of the lower end of the panel during continuous panel transfer, and the axis of the guide sprocket is aligned. By bending the panel to a position directly below, the front-back direction of the panel that occurs at the time of the above-mentioned direction change in the transfer process in which each panel is changed to the vertical posture along the guide rail and the horizontal storage posture along the storage rail The bottom edge of the panel can be made to follow the horizontal and downward movement of the top edge without fail, and even when the shutter is opened and closed at high speed, the opening and closing operation is always smooth and reliable. Moreover, it is an object of the present invention to provide a panel guide guide device for a panel shutter that can be carried out lightly.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the technical means adopted by the present invention is that each of a plurality of panels is provided with an upper roller on both side edges of the upper panel via a support shaft. , The lower guides are provided on both side edges of the lower part, and the supporting shaft is hung on a roller chain, and the panels are vertically moved vertically in conjunction with forward and reverse rotation drive of an induction sprocket meshing with the roller chain. And the horizontal movement in the horizontal direction, the vertical movement is performed along the guide rails erected on both sides of the opening, and the horizontal movement is connected to the guide sprocket and is horizontally provided in the storage rail. And a panel guide rail that continuously guides the lower end of the panel from the sprocket connecting area of the panel to the horizontal movement area, and the guide body is guided along the lower surface of the panel guide rail. It is characterized in that it is configured to be inside.

[Embodiment] The configuration of the present invention will be described in detail based on an embodiment shown in the drawings.

In the figure, reference numeral 1 denotes a panel shutter, and the panel shutter 1 is provided with bearing members 2 at both ends of an upper frame 2a of a plurality of elongated panels 2 arranged at predetermined intervals in the vertical direction.
The roller shafts 3 are respectively fitted and inserted through b, and the panels 2 are pivotally connected in series by a roller chain 4 attached to the roller shafts 3. A roller 5 is rotatably supported by the roller shaft 3.

6 is a guide rail standing on both sides of the building opening, 7
Is a guide guide formed at the upper end of the guide rail 6, and 8 is a shutter housing case. The shutter housing case 8 is guided inside the left and right side plates 9 coaxially with a drive sprocket (not shown). A sprocket 10 is pivotally supported, and a roller chain 4 is meshed with the guide sprocket 10.

Reference numeral 11 denotes a storage rail that is horizontally arranged inside the left and right side plates 9. The storage rail 11 is a guide sprocket 10.
By rolling the rollers 5 of the respective panels 2 that have moved upward in association with the rotation of the panels, the panels 2 are guided horizontally in a state of being vertically arranged in parallel.

Reference numeral 12 is an extension rail extending upward from the guide end portion of the guide rail 6, and the extension rail 12 is formed of an outer guide plate 12a and an inner guide plate 12b, and the inner guide plate 12b. A panel guide rail 14 is disposed below the storage rail 11 at the guide end portion of the.

The panel guide rail 14 includes the inner guide plate 12
Between the joint end of b and the position directly below the axis of the guide sprocket 10, the curved shape is formed along the joint locus of the lower end of the panel when the panel 2 is jointed. Is installed in parallel with the storage rail 11 below and is configured to continuously guide the lower end portion of the panel 2 between the sprocket transfer area and the horizontal movement area of the panel 2. .

On the other hand, 13 is each panel 2 constituting the shutter curtain
Is a pin-shaped guide body (guide pin) projectingly provided at the lower end portion of the panel guide rail 13 when the panel 2 moves up and down the extension rail 12 when the shutter 1 is opened and closed. The lower end of the panel is guided along the lower surface of 14 to prevent the panel 2 from swinging in the front-rear direction. The guide body 13 is not limited to the shape of the guide pin, and may be a guide roller.

In the above configuration, when an opening signal is sent to the panel shutter 1 that is closing the opening of the building,
Induction sprocket 1 by starting the drive of a switch (not shown)
0 is rotationally driven, and each panel 2 connected by the roller chain 4 moves upward along the guide rail 6.

Next, in the process of moving the extension rail 12 upward from the guide end of the guide rail 6, the guide body 13 projecting from the lower end portion of the panel 2 has a connecting end portion of the panel guide rail 14 as shown in FIG. Abut on the back side of the guide sprocket 1
In the continuous process of moving up by the rotation of 0, while being guided and guided along the curved surface of the panel guide rail 14, the moving direction is gradually changed from the rising position along the guide rail 6 to the horizontal storage position. Panel 2
The lower end of the sprocket follows the movement of the upper end of the panel in the sprocket transfer area and is continuously transferred along the panel guide rail 14.

After that, when the roller 5 supported by the roller shaft 3 is continuously transferred onto the storage rail 11 of the shutter storage case 8 while maintaining a state in which there is no wobbling in the front-rear direction, the roller 5 rolls along with it. Each of the panels 2 is horizontally guided and stored in a state where the guide body 13 at the lower end thereof is placed along the lower surface of the panel guide rail 14 in parallel with each other.

Therefore, when the shutter 1 is opened, the fear that the ascending path of the succeeding panel 2 will be blocked and the collision will occur due to the swinging of the upper panel 2 in the front-rear direction is eliminated, and the opening operation can be performed surely and lightly. You can

Also, when closing the shutter 1, the storage rail 11
The roller shaft 3 of the panel 2 that moves horizontally above contacts the guide body 13 against the back surface of the curved surface of the panel guide rail 14 while the roller shaft 3 of the panel 2 moves from the joint end of the storage rail 11 to the joint region of the guide sprocket 10. At the same time, as the guide sprocket 10 is rotated, the movement direction is changed from the horizontal direction to the descending direction and the guide sprocket 10 is guided and guided along the curved surface of the panel guide rail 14 until it passes through the extension rail 12.
The lower end of the forcibly follows the movement of the upper end when changing direction, and descends while maintaining the state of no shake in the front-back direction,
The guide rails 6 are sequentially arranged on the same plane while being supported by the guide rails 6, and the opening of the building is closed.

Therefore, as in the conventional case, when the direction is changed from the horizontal direction to the downward movement, the lower end portion of the panel 2 lags behind the movement of the upper end portion and is not guided into the guide guide 7 located at the upper end portion of the guide rail 6. Therefore, the closing operation can always be performed reliably and lightly without causing such a problem.

[Advantages of the Invention] In summary, according to the present invention, each of the plurality of panels is provided with an upper roller at both upper side edges thereof via supporting shafts, a lower guide body is provided at both lower side edges thereof, and The shaft is suspended in a roller chain, and in conjunction with forward and reverse rotation drive of an induction sprocket that meshes with the roller chain, in order to transfer each panel to vertical movement in the vertical direction and horizontal movement in the horizontal direction, The vertical movement is performed along the guide rails standing upright on both sides of the opening, and the horizontal movement is from the sprocket joint area of the panel and the horizontal storage rail that is connected to the guide sprocket to the horizontal movement area. The shutter is opened and closed because it is configured to be guided by a panel guide rail that continuously guides the lower end portion of the panel between the guides and the guide body is guided and guided along the lower surface of the panel guide rail. At this time, the front and rear runout of the panel that occurs during the transfer process that changes the direction of each panel between the up and down posture along the guide rail and the horizontal storage posture along the storage rail, and the lower end of the panel relative to the movement of the upper end of the panel It is possible to reliably prevent the delay of the parts, and it is possible to forcibly follow the vertical movement of the lower end of the panel and the horizontal storage posture to the integrated vertical movement and horizontal movement with respect to the upper end of the panel. Even when the shutter is opened / closed at high speed, the opening / closing operation of the shutter can be smoothly and reliably performed smoothly and lightly, which is a very useful new effect.
