Description

Description: TECHNICAL FIELD The present invention relates to a shutter provided in an opening of a building or a shroud window, and particularly to a shutter using a panel.

(Prior art) Conventionally, a thin steel plate or a light alloy plate called a slat has been used as a plate-like body that is a main component of a shutter provided at an entrance of a building or the like. Recently, shutters using panels instead of slats have also appeared. Such a panel shutter is not limited to a metal material, and various materials such as synthetic resin and glass can be used as the material of the panel. A variety of uses are being considered, such as providing lighting means for the vehicle. When glass is used for the panel surface, since the inside can be seen through, it is conceivable that a store or the like can show a display inside the store after the shutter is closed, and may not be available from a conventional shutter.

Furthermore, since ventilation and lighting can be performed by rotating the panel surface, there are many surfaces that are superior to slat shutters in which it is difficult to perform ventilation and lighting in the closed state.

However, the conventional method for rotating the panel surface is to raise the closed shutter a little, and to tilt the panel surface by making use of the gap between the panels. It has a problem that it is stable and it is difficult to perform locking in an inclined state.

Also, in the conventional panel shutter, the length between the panels in the connecting member such as the connecting chain is made larger than the panel pitch in order to smoothly move the panel between the storing section and the storing rail. In the process of moving the panel, there is a problem that a gap is generated between the panels and a finger is erroneously pinched.

(Problems to be Solved by the Invention) The present invention has been made in order to solve the above-mentioned problems, and it is possible to raise and lower a shutter without generating a gap between panels, and to fix an out frame when the shutter is closed. It is an object of the present invention to provide a panel shutter that can open and close a panel surface in a state.

(Means for Solving the Problems) According to the present invention, a plurality of panels each having an out frame that rotatably supports a panel member and is guided by a guide rail to move up and down, and are driven by a driving mechanism to move the panel up and down. A connecting member having an engaging portion provided at the same pitch as that of the panel, and suspending the panel and engaging with the engaging portion of the connecting member to move the engaging portion downward with respect to the out frame. A rotating member for rotating the panel member by the relative movement of the shutter, and a moving member for driving the connecting member so as to move the vicinity of the engaging portion of the lower panel downward when the shutter is closed. It is assumed that.

(Embodiment) FIG. 1 is a perspective view of a main part for explaining an open / close state of a panel member in a panel shutter according to an embodiment of the present invention. Here, a lower panel and a position above the lower panel are shown. Only the panel to be used is shown. In the figure, 1A and 1B are panel members, 2A and 2B are out frames, 3A and 3B are support rollers, 4
A and 4B are engaging parts, 5A and 5B are support shafts, 6A and 6B are rotating levers, 7
A and 7B are panel support shafts, 8 is a connecting chain, 9 is a wing chain, and 10 is a driven sprocket. Panel members
1A and 1B are out frames 2A and 2B by panel support shafts 7A and 7B.
B is rotatably supported. Also, panel members 1A, 1B
Has one end fixed to the rotating levers 6A and 6B,
Support shafts 5A and 5B are fixed to the other ends of A and 6B. A connection chain 8 is rotatably engaged with the support shafts 5A and 5B at engagement portions 4A and 4B, and support rollers 3A and 3B are supported by the shafts. In addition to the supporting shaft 5A at the lower end, a wing chain 9 is engaged similarly to the connection chain 8.
The length between the engagement portions in the connection chain 8 is set equal to the pitch interval of the panel. The upper and lower portions of the out frame are adapted to engage diagonally as shown.

The opening and closing operation of the panel member will be described. Figure 1
While the panel members 1A and 1B are shown rotated, the support shafts 5A and 5B are hung by the engagement portions 4A and 4B by the connecting chain 8 in the elevating state.
It moves up and down while rotating in the opposite direction to 11. The out frames 2A, 2B may be provided with stoppers for restricting the rotation of the panel members 1A, 1B, but an appropriate weight balance can be obtained depending on the length of the rotation lever and the weight and height of the panel member. , Does not necessarily require a stopper. If the height of the panel member is greater than the panel pitch, the third
As described in the figures, the lower end of the panel member is in contact with the upper end of the panel member below the lower end in the elevating state. Therefore, it is not always necessary to provide the stopper. In any case, when the shutter is closed and all the outframes are lowered, the panel member is closed. Here, when the wing chain is moved in the direction of arrow 12, the engaging portion 4A of the lower panel member 1A moves relatively downward with respect to the out frame 2A, and the rotating lever 6A is rotated. Then, the panel member 1A is opened by rotating in the direction of arrow 11. At the same time, since the connecting chain 8 is moved downward, all the panel members are similarly opened. To close the opened panel member, the connection chain 8 may be slightly wound up.

Note that the support shaft 5A may be driven downward by a lever or the like provided on the building skeleton side without using the wing chain. It is clear that the rotation lever 6A of the lower end panel may be driven by other means.

FIG. 3 is a schematic diagram for explaining the open / close state of the entire shutter described in FIG. Although the number of panels is set to 5, it is not limited to this. In the figure, 1 is a panel member, 2 is an out frame, 3 is a supporting roller, 8 is a connecting chain, 9 is a wing chain, 10 is a driven sprocket, 13 is a connecting chain driving sprocket, and 14 is a wing chain driving sprocket. , 15 is a storage rail, 16 is a storage part, 17 is a guide rail, and 18 is a locking part.

The panel having the out frame 2 supporting the panel member 1 is suspended by the connecting chain 8 by the above-described engaging portion. The connecting chain 8 is driven by a connecting chain driving sprocket 13, and the wing chain 9 engaging only with the lower panel is used when the panel 2 is moved up and down.
14 drives at the same speed as the connecting chain 8. However, when the panel 2 is moved up and down, the wing chains 9
It is not always necessary to apply a driving force to the wing chain 9 by providing a clutch or the like between the driving mechanism of the wing chain driving sprocket 14 and disengaging the clutch to make the rotation free. May be driven by the connection chain 8.

FIG. 3A shows an open state of the shutter. In this state, the panel except the lower end panel is stored on the storage rail 15 of the storage unit 16 by the support roller 3. All panels may be stored on the storage rail.

The closing of the shutter is performed by rotating the connecting chain driving sprocket 13 in a counterclockwise direction as shown in FIG. As described above, even if the wing chain 9 is driven,
Alternatively, it may be made free. In this case, since the panel is hung on the connecting chain at an interval equal to the panel pitch, no gap is generated between the panel members. Further, since the portion where the out frame abuts with the adjacent out frame is formed in an oblique shape, the panel can be smoothly moved near the sprocket for driving the connecting chain.

FIG. 3C shows a state in which all the panels are lowered and the shutter is closed. At this time, the locking portion 18 can be operated to lock the notch portion or the like provided in the out frame of the upper panel so that the locking portion 18 is engaged.

In the state shown in FIG. 3C, the wing chain drive sprocket 14 is rotated clockwise to move the engagement portion with the lower end panel downward, thereby allowing the panel member to move as described with reference to FIG. Can be rotated about the panel support shaft to open the panel. Also, if the connecting chain is slightly wound up, the opened panel can be closed.

To open the closed shutter, rotate the connecting chain drive sprocket in the opposite direction to that described above, pull up the panel sequentially in the reverse procedure to the above, and move the panel onto the storage rail 15 while storing it. I do. At this time, the wing chain may be driven as described above or may be free. During the ascent process,
Obviously, there is no gap between the panels.

FIG. 2 is a perspective view of a main part for explaining an open / close state of a panel member in a panel shutter according to another embodiment of the present invention. In the figure, the same parts as those in FIG. In this embodiment, since the connecting chain can be located near the center of the out frame, the width of the guide rail can be reduced as compared with FIG. Although the support rollers 3A and 3B are provided on extensions of the panel support shafts 7A and 7B, they may be provided on the support shafts 5A and 5B as in FIG. The pivot levers 6A, 6B and the panel members 1A, 1B are rotatably mounted, and the support shafts 5A, 5B are attached to the out frames 2A, 2B.
When the shutter is closed, when the wing chain is moved downward, the rotating levers 6A and 6B rotate according to the position, and the panel members 1A and 1B are moved. The panel member can be opened by rotating around the panel support shafts 7A and 7B. To close the panel members, the connection chain 8 may be pulled up.

In addition, in FIG. 2, when this shutter is attached to the outer wall of the building frame, both the left and right in the figure can be indoors. From the viewpoint of the rain, it is advantageous to set the right side as the outdoor side, and the storage portion can be formed in an eaves shape.

(Effects) As is clear from the above description, according to the present invention, no gap is generated between the panels during the elevating and lowering of the panel shutter. Since it is possible to prevent an accident in which a foreign object is caught and to open and close the panel member, there is an effect that a panel shutter excellent in ventilation and lighting can be provided.
