Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a shutter device with an improved means for opening and closing a shutter panel.

[Conventional technology]

A conventional shutter device of this type has vertical guide rails arranged on both sides of the shutter opening/closing opening, a panel storage box connected to the upper end of the vertical guide rail, and a box that can be moved from the vertical guide rail into the box. a plurality of panels connected by the chain and adjacent to each other in the vertical plane direction between the vertical guide rails; and the chains are arranged on the upper end side of the vertical guide rail and are engaged with each other and driven to rotate. It is configured with a sprocket.

Then, when the sprocket is driven in the forward direction, the panels in the box are pulled out to the vertical guide rail through the chain and lowered, so that each panel is held in a vertical plane by the vertical guide rail, and the panels are held vertically in the opposite direction of the sprocket. The panel is pulled up by a chain by rotational drive and stored in the box.

[Problem that the invention attempts to solve]

The conventional shutter device mentioned above has a problem in that the box for storing the panel is provided at the upper end of the vertical guide rail, so the box is always exposed at the upper part of the room, and especially the upper space in the room. However, there was a problem in that if the box was on the upper side, the shutter device could not be installed.

This idea was made to solve the above problems, and it is possible to install a box for storing panels on the floor or under the floor, and it is possible to raise the panels continuously and smoothly from the box. To provide a shutter device capable of smoothly storing the panel in a box.

[Means for solving problems]

In the shutter device according to this invention, a box for storing a panel is provided at the bottom of a pair of left and right vertical guide rails arranged on both sides of an opening for opening and closing the shutter, and both sides are engaged with the vertical guide rails so as to be able to move up and down. multiple vertically adjacent panels,
A chain guide member is provided on the vertical guide rail, the chain guide member meshing with a sprocket disposed near the lower end of the vertical guide rail to connect the vertical guide rail and the box by a chain spanning the box, and preventing the chain from bending. It is something that

[Effect]

In this invention, when the sprocket is driven to rotate in the forward direction with the panel housed in the box, the chain is fed out from inside the box onto the vertical guide rail. At this time, the chain is prevented from bending by the chain guide member provided on the vertical guide rail, and the chain rises in the form of a bar along the vertical guide rail. Close the opening/closing opening. When the sprocket is driven to rotate in the reverse direction from this state, the chain descends and enters the box, thereby housing the panel within the box.

〔Example〕

An embodiment of this invention will be described below based on the drawings. In the figure, 1 is a pair of left and right vertical guide rails placed on both sides of the opening for opening and closing the shutter, and a box 2 for storing the panel is located at the lower end of the rail.
are arranged in series.

Inside this box 2, there is the vertical guide rail 1.
A support rail 3 for storing panels (see Figures 3 and 5) whose front end side is connected to the lower end side and whose rear end side gradually slopes downward, and a sprocket 4 pivotally supported on both sides of the front end of this support rail 3. and are arranged.
The sprocket 4 is driven to rotate in forward and reverse directions by a driving means 5.

Such a sprocket 4 has a vertical guide rail 1.
A chain 6 is engaged with the box 2 and the box 2, and this chain 6 connects a plurality of vertically adjacent panels 7 and 8 between the vertical guide rails 1.

More specifically, horizontal shafts 9 are protruded from both upper sides of each panel 7, 8, and the horizontal shafts 9 of each panel 7, 8 are connected to each other by a chain 6.

A guide roller 10 is provided on the horizontal shaft 9, and both upper sides of each panel 7, 8 are engaged with the vertical guide rail 1 in a vertically movable manner via the guide roller 10, so that the support rails in the box 2 can be moved up and down. It is now possible to move to 3.

Inside the vertical guide rail 1 is a chain guide member 11 that movably inserts the chain 6 within a certain height range from its lower end to prevent the chain from bending.
(See FIGS. 2 to 5).

The chain guide member 11 of this embodiment has a box-shaped cross section and is provided with a vertical guide hole 11a inside, and the chain 6 is movably fitted into this vertical guide hole 11a.

In this case, the chain guide member 11 has a length from when the guide roller 10 of the uppermost panel 7 that enters from the bottom of the vertical guide rail 1 and rises passes until the guide roller 10 of the next panel 8 enters. Set.

Next, the operation of the above embodiment will be explained. The guide rollers 10 of each panel 7, 8 are supported on the support rail 3 in the box 2, so that the sprocket 4 rotates in the normal direction when the panels 7, 8 are folded parallel to each other and are held suspended. When driven, the chain 6 that meshes with this is pushed up by the vertical guide rail 1 from below. At this time, the chain 6 is prevented from bending by the chain guide member 11, so that the chain 6 becomes rod-shaped and is pushed up the vertical guide rail 1. As a result, when the uppermost panel 7 moves up the vertical guide rail 1 and its guide roller 10 passes through a considerable distance of the chain guide member 11, the chain guide member 1
1, the chains 6 on both sides of the top panel 7 are removed, but the chains 6 on both sides of the next panel 8 enter the chain guide member 11 and rise, so that the top panel 7 is removed from the next panel. Pushed up by 8. By repeating this one after another, the subsequent panels 7 and 8 are raised one after another to close the openings such as windows between the vertical guide rails 1.

When the sprocket 4 is driven to reverse rotation from this state, the chain 6 descends the vertical guide rail 1 and enters the box 2, and the guide roller 10 moves from the vertical guide rail 1 onto the support rail 3 in the box 2. By shifting, the panels 7 and 8 are sequentially stored in the folded and suspended state within the box 2.

In the above embodiment, the chain guide member 11 may be provided over substantially the entire length of the vertical guide rail 1.

[Effect of idea]

In this invention, a box for storing panels is provided at the bottom end of the vertical guide rail, so this box can be installed on the floor or under the floor.
Therefore, the shutter device can be easily and neatly installed even in places where the space above the shutter installation location is restricted, without exposing the box above the shutter installation location.

Moreover, since the vertical guide rail is provided with a chain guide member that connects each panel and prevents the chain moved by the sprocket from bending, the vertical guide rail cannot push the chain up into a rod shape. Therefore, each panel can be raised smoothly and reliably along the vertical guide rail.
