Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a panel shutter device that opens and closes an opening by lifting and suspending a shutter made by vertically connecting and suspending a plurality of panels. .

[Prior Art] A panel shutter device is generally constructed by connecting and suspending both side edges of a plurality of panels in a series with roller chains, and the shutter is linked to the forward and reverse rotation of an induction sprocket that engages with the roller chain. The panels are then hung up to close and open the opening, but the running rollers installed on both sides of the hanging special panel are guided by guide rails erected on both sides of the opening, and each panel becomes a vertical plane. They are arranged to close the opening, and the hanging special number panels are sequentially fed into storage rails provided above the opening in the front-rear direction and suspended in parallel by the traveling rollers to open the opening. When the panels are fed into the storage rail and hung in parallel, the chains connecting and suspending the panels slacken and hang between the edges of each panel and the bracket.

However, in conventionally known panel shutters, the positional relationship between the running roller and the roller chain is such that the running roller is placed inside the hanging part of the roller chain, so it does not interfere with the hanging of the roller chain during storage. Therefore, the rail cannot be directly supported by the bracket from a position near the rollers, and the rail strength must be maintained not only in the hanging direction but also in the left and right directions. It has the disadvantage that it has to be done.

Moreover, the structure is complicated, such as having to have a double structure in which the bracket and the rail are spaced apart from each other, and there are disadvantages in that it is not possible to create a compact structure.

[Problems to be Solved] The present invention has been made in view of the actual situation of the conventional panel shutter device as described above, and has been made to improve this, and its purpose is to provide a shutter case with a simple structure, Moreover, it can be stored in a lightweight and compact manner, ensuring stability against panel deflection when moving laterally along storage rails, and ensuring that the panel remains vertical even when exposed to wind pressure from the lintel when the panel is extended. The present invention aims to provide a panel shutter device that is conveyed to the guide rail of the vehicle.

[Means for Solving the Problems] In order to achieve the above object, the technical means adopted by the present invention is that a plurality of panels are suspended by roller chains via support shafts provided on the left and right sides of each panel. A panel shutter device configured to perform vertical movement along a guide rail in the vertical direction and lateral movement along a storage rail in the front and back direction in conjunction with the forward and reverse rotation of the guide sprocket. A running roller protruding from the side edge of the panel is arranged outside the hanging portion of the roller chain and configured to roll on a storage rail outside the roller chain hanging portion, and The suspended roller chain is characterized in that it is pivotally connected to a support shaft provided directly on the upper edge of the panel.

[Embodiment] The configuration of the present invention will be described based on an embodiment shown in drawing 1. Reference numeral 1 denotes a panel shutter provided at an opening of a building, and the panel shutter 1 is arranged at predetermined intervals in the vertical direction. A plurality of panel bodies 2.2... arranged according to
It is constructed by being connected and pivoted in a series to a roller chain 4 via support shafts 3 disposed on the upper side of both left and right ends thereof.

Each panel body 2 is formed in the shape of a long plate that is long in the horizontal direction, and has a protruding strip 2a on its upper edge over the entire length in the longitudinal direction.
is formed, and a groove 2b into which the protrusion 2Q is tightly fitted is formed on the upper edge. Reference numeral 5 denotes guide rails vertically installed on both the left and right edges of the opening, and the panel shutter 1 is guided by the guide rails 5 so as to be raised and lowered in a vertically hanging state. Above the guide rail 5 is a storage case 6.
is provided, but the bracket 6' of the storage case 6 is
A storage rail 6a facing horizontally and laterally is laid inside.

Reference numeral 7 denotes an induction sprocket disposed above the upper end of the guide rail 5, and the induction sprocket 7 is rotated forward and backward by a drive mechanism (not shown). JA! ! The opening is opened and closed by lifting and suspending a roller chain 4 which is supported in a cantilevered manner by an Il shaft 7a and which engages with an I guide sprocket 7. The guide sprocket 7 located above the guide rail 5 is configured to mesh with the roller chain 4 at a position that is biased towards the storage rail 6a side from the upper extension line of the guide rail 5, so that the upper end of the guide rail 5 An inclined transfer rail 8 is formed between the guide sprocket 7 and the guide sprocket 7. The panel body 2 lifted up along the diagonal transfer rail 8 in this way is
It is adapted to be transferred to the storage rail 6a side by the I-guide sprocket 7. 9 is a running roller that rolls on the guide rail 5, the inclined transfer rail 8, and the storage rail 6a.

As is clear from the above configuration, the panel body 2...
is suspended by a roller chain 4 on the inverted side of a support shaft 3 provided at the upper edge of the panel body 2.

The running rollers 9 are located outside the hanging parts 4a of the roller chain 4 and roll on storage rails 6a located outside of the hanging parts 4a of the roller chain 4.

[Function] Next, the function of the present invention constructed as described above will be explained.

First, the opening operation of the panel shutter 1 is performed by rotating the induction sprocket 7 in the forward direction and lifting the roller chain 4, so that the panel bodies 2.2, which are arranged in series in the vertical direction, are sequentially arranged in a series starting from the topmost one. This is done by being conveyed from the guide rail 5 to the storage rail 6a side via the transfer rail 8, and stored in the storage case 6 in a horizontally parallel manner. on the other hand.

The closing operation of the panel shutter 1 is performed by the induction sprocket 7.
By rotating the roller chain 4 in the opposite direction and suspending the roller chain 4, the roller chain 4 is transferred from the storage rail 6a to the guide rail 5 side by the reverse scraping. At this time, the concave grooves of the upper panel body 2 tightly fit into the protrusions 2a of the lower panel body 2, so that the panel shutter 1 is closed without any gap.

In this series of opening and closing operations, the induction sprocket 7
The panel body 2 rises by the rotation of.

The panel body 2 is transferred from the upper end of the guide rail 5 through the inclined transfer rail 8 to the storage rail 6a side. Since the panel body 2 is suspended by the roller chain 4, it is possible to minimize the back and forth shaking of the panel body 2 during transportation. Therefore, even if the panel body 2 moves up and down at high speed, the following lower panel body 2 will not be able to hold the upper panel body. 2. Smooth lifting and lowering operations can be performed without colliding with other objects.

Moreover, in this embodiment, when the shutter is opened and closed, the panels 2, 2, etc. are suspended by the chain 4 on the bowed side of the support shaft 3, so the panel load applied to the mounting portion of the support shaft 3 is small. Therefore, there is no risk of the support shaft 3 being bent or breaking, and therefore, even if the support shaft 3 is made of a small diameter one, not only can the safety in terms of fall prevention be improved, but also the support shaft 3 can be easily bent or broken. Provided directly on the panel body 2.

A roller chain 4 is pivotally connected to the support shaft 3, and a running roller 9 is disposed outside the hanging portion 4a of the roller chain 4. It is configured to roll on the storage rail 6a, and has a four-body structure consisting of a panel body, a support shaft, a roller chain, and a traveling roller, so that when the panels 2 are stored, a roller is placed between each panel 2 and the bracket 6'. Although the chain 4 hangs down, the storage rail 6a can be directly supported by the bracket 6' of the storage case 6 over its entire length.
As for the rail strength, it is only necessary to consider the strength in the hanging direction, and there is no need for strength in the left and right directions, so not only can it be handled with a simple rail member, but the entire storage case 6 can be constructed with a simple structure, that is, with running rollers. 9 and the bracket 6' or the distance between the running roller 9 and the edge of the panel 2 can be made as close as possible to the drive shaft supported in a cantilevered manner on the bracket 6'. The shaft 7a can be shortened, and the induction sprocket 1-7 and the drive sprocket 7' can be closely opposed to each other, so that even though the drive shaft 7a is supported in a cantilevered manner,
Lifting load of panel 2.

In addition to being able to maintain sufficient strength against hanging loads, the case width can be reduced to provide a compact housing.

Furthermore, the suspended roller chain 4 is directly pivotally connected to the support shaft 3 provided on the upper edge of the panel 2.
Even if the panel 2 receives wind pressure from the lintel when it is fed out, the swinging inertia weight can be increased and the swinging against the wind pressure can be reduced, ensuring reliable transfer to the vertical guide rail. This allows for high-speed opening and closing.

Furthermore, since the support shaft 3 is suspended by the rollers 4 on the outside during storage, even if the load applied to the attachment part of the support l1ilII3 is greater than when it is moved laterally along the guide rail,
Since it is inside the case, the panel will not fall directly.
Safety can be made extremely high.

In the above embodiment, the transfer path is configured as an inclined transfer rail 8, but the present invention is not limited to this, and as shown in FIG. An inclined transfer path may be formed between the upper end and the guide sprocket 7, and as shown in FIG. A rail 11 may be provided, and the following lower panel body 2 may be moved outwards relative to the upper panel body 2 that moves upward R0 on the same upward trajectory as the guide rail 5, and may be configured to have an aI pattern as much as possible. Auxiliary sprocket as shown in Figure 6! - 12 may be provided to form an inclined transfer path.

[Effects of the invention] A plurality of panels are suspended by roller chains via support shafts provided on the left and right edges of each panel, and are moved along the guide rail in the vertical direction in conjunction with the forward and reverse rotation of the guide sprocket. In a panel shutter device configured to perform vertical movement and lateral movement along a storage rail in the front and back direction, a running roller protruding from the side edge of the panel is provided.
The roller chain is arranged outside the hanging part and configured to roll on a storage rail outside the roller chain hanging part, and the suspended roller chain is directly attached to the upper edge of the panel. Although it has a simple structure with a four-body structure consisting of a panel, support shaft, roller chain, and running roller, the storage rails are connected directly to the storage case along the entire length. For this reason, the rail strength only needs to be considered in the hanging direction, and strength in the left and right directions is not required, so not only can panels be stored with simple rail members, but Flff the entire storage case! l
In other words, the distance between the running roller and the bracket or the distance between the running roller and the edge of the panel body can be made as close as possible. This makes it possible to shorten the drive shaft, allowing the induction sprocket and drive sprocket to face each other in close proximity, and even though the drive shaft is supported in a cantilevered manner, it is difficult to withstand the lifting load and hanging load of the panel. Sufficient strength can be maintained, and the width of the case can be reduced to make it compact. Furthermore, since the panel is suspended by a roller chain pivotally connected to a support shaft provided directly on the upper edge of the panel, it can withstand wind pressure from the lintel of the panel when it is unrolled. The inertial weight of the swinging increases, and the swinging due to wind pressure decreases, so it is possible to minimize the back-and-forth swing of the panel body during transport, ensuring reliable transfer to the vertical guide rail. Therefore, even if the lower panel moves up and down at high speed, the following lower panel will not collide with the upper panel and the 51. It can perform lowering operation and can handle high-speed opening and closing. Furthermore, since the panel is suspended by the rollers on the outside of the support shaft when stored, even if the load applied to the mounting part of the support shaft becomes greater than when moving laterally along the guide rail, the panel will fall directly because it is inside the case. There is no risk of
This has extremely useful practical effects.
