Description

[Detailed description of the invention] This invention relates to a panel-type shutter device that can store shutter panels connected by a chain in a folded state without involving the panels. The present invention relates to a panel type shutter device that can smoothly engage or disengage from a panel drive sprocket.

Recently, multiple tiers of upper and lower panels connected by a chain are developed in the same vertical plane between a pair of left and right vertical guide rails placed on both sides of the shutter opening/closing opening, and these panels are connected to the above guide rails. A panel type shutter device is provided in which each of the panels is suspended in a parallel and adjacent folded state when the panels are moved and stored in a storage box above the rail.

This type of conventional panel shutter device is
It has many advantages, such as less noise generated when the panel moves, the ability to widen the panel width, and an excellent appearance.

However, in the conventional panel type shutter device described above, it is difficult to always smoothly perform the folding and storing operation of the panel from between both guide rails into the storage box and the operation of pulling out the panel from inside the storage box to between the guide rails. However, there are problems in that an extremely complicated panel driving device is required to ensure smooth operation of such panels. In particular, when the panel with the shutter closed and drawn out between both guide rails is rolled up and stored in the upper storage box, it is connected by a chain that meshes with the panel drive sprocket, and both ends are engaged with both guide rails so that they can move up and down. In this case, if the panels are left as they are, there is a risk that the upper and lower multiple panels that rise along the guide rails may fold or become jammed during the rising process, causing the panels to become stuck.
Since the panel driving sprocket with which the panel connecting chain is engaged is in operation, there is a problem in that the panel driving sprocket, the panel connecting chain, the panel, etc. may break, causing a major accident.

This idea was made to solve the above problem, and it allows the panel connecting chain to smoothly engage or disengage from the panel drive sprocket while the panel is moving up and down along the guide rail. It is possible to prevent irregular and harmful engagement between the panel connecting chain and the panel drive sprocket,
An object of the present invention is to provide a highly reliable panel type shutter device capable of smoothly and efficiently performing panel raising and lowering operations at all times.

The shutter device of this invention is placed in a storage box above the guide rail, near the panel drive sprocket with which the panel connection chain is engaged, and the panel connection chain is positioned in the direction of engagement with the panel drive sprocket during the process of raising and lowering the panel. Alternatively, a chain/sprocket guiding device is arranged to guide the chain/sprocket in the direction of disengagement, and the chain/sprocket guide device contacts the panel connecting chain in the direction of engagement or disengagement on the side of the support rail near the panel drive sprocket. It has at least one of a panel storage side chain guiding member for guiding the chain, or a panel entrance side chain guiding member for contacting and guiding the panel connecting chain in the engagement direction or the disengagement direction near the upper end side of the guide rail. .

In the shutter device of this invention, when the panel is raised or lowered, the panel connecting chain near the panel drive sprocket is connected to the panel drive sprocket by at least one of the panel storage side chain guide member or the panel entrance side chain guide member. Since the contact is guided in the direction of engagement or disengagement with the panel drive sprocket, irregular engagement of the panel connecting chain with the panel drive sprocket can be prevented in advance and reliably, and the panel lifting and lowering operations can be performed smoothly and efficiently at all times. This improves the reliability of the panel type shutter device.

An embodiment of this invention will be described below based on the drawings.

The shutter device according to this invention includes a pair of left and right guide rails 1 and a plurality of upper and lower panels 2 whose both sides are engaged with these guide rails 1 so as to be able to move up and down.
and a pair of left and right panel connecting chains 3 which connect these panels 2 at both upper ends thereof so as to be rotatable and movable in the thrust direction, and move up and down along both guide rails 1.

The guide rail 1 consists of a pair of left and right vertical guide rails placed on both sides of a so-called shutter opening/closing opening such as an entrance/exit of a building or a window, and a storage box 5 is placed above it. A support rail 4 is disposed for mooring a part of the panel connecting chain 3 and suspending the panels 2 in a parallel and adjacent folded state.

This support rail 4 is arranged above the panel entrance/exit in the storage box 5 and gradually slopes downward in the direction of panel storage from near the panel drive sprocket 8 that engages the panel connection chain 3. There is.

Near and above the support rail 4, the parallel chain tip guide rod 6 is arranged.

As shown in the first diagram, this chain end guide rod 6 is movably fitted loosely at the end of the panel connecting chain 3, so that it moves along with the panel 2 to the panel connecting chain 3 during the first storage operation of the panel 2. moves, and the panel connecting chain 3 of the first panel 2 does not hang down and become entangled.

Further, on the upper end side of the guide rail 1 in the storage box 5, there is a chain slack sensor located near the panel drive sprocket 8 to electrically sense abnormal refraction (slack) of the panel linking chain 3. A device 7 is provided.

Furthermore, in the vicinity of the panel driving sprocket 8 in the storage box 5, there is a sprocket that contacts the panel connecting chain 3 and causes the panel connecting chain 3 to Chain guiding members 9 and 10 are arranged to reliably separate the panel connecting chain 3 from the panel driving sprocket 8 in a predetermined moving direction, or to guide the panel connecting chain 3 into contact with the panel driving sprocket 8 in a predetermined meshing direction.

More specifically, it is arranged near the panel drive sprocket 8 on the side of the support rail 4, and is used to guide the panel connection chain 3 into contact with the panel drive sprocket 8 in a predetermined engagement direction or disengagement direction. by at least one of the panel storage side chain guide member 9 and the panel entrance/exit side chain guide member 10 that contacts and guides the panel connecting chain 3 in the engagement direction or the disengagement direction near the upper end side of the guide rail 1. A chain sprocket guiding device is constructed.

Further, near the panel entrance/exit of the storage box 5, a panel guide 11 is provided to smoothly guide the lower end of each panel 2.

The panel connecting chain 3 is as shown in FIGS. 1 and 5 (the two-dot chain line is actually in a symmetrical position with respect to the panel axis from the illustrated position, but is shown in the opposite position for convenience of the drawing). It is arranged along the panel guide 11. and,
The tip of the panel connecting chain 3 is loosely fitted into the chain tip guide rod 6.

Further, inside the storage box 5, a panel driving means (opening/closing machine) 13 and a panel driving means 13 are provided.
A main drive side rotating shaft 16 is interlocked with the main drive side rotating shaft 16 via an interlocking chain 15 and an interlocking sprocket 14 and is rotatably supported on both side walls of the storage box 5 via bearing members, and a main drive side rotating shaft 16 is provided at both ends of the main drive side rotating shaft 16. The connected first transmission sprocket 17, the panel driving sprocket 8, and the second transmission sprocket 1
A driven side rotating shaft 20 coaxially connects the two transmission sprockets 8 and an endless transmission chain 19 wound and meshed with the first transmission sprocket 17 and the second transmission sprocket 18, respectively.

On the other hand, as shown in FIGS. 6 and 7, each of the panels 2 has a rectangular frame 2a and an appropriate panel face plate 2b such as a glass plate attached thereto.

A pin 21 is protruding from both ends of the upper part of the rectangular frame 2a, and is inserted into and engaged with the panel connecting chain 3 so as to be rotatable and movable in the thrust direction.
A shaft 23 is protruded from both sides of the lower part of the panel, and a panel roller 22 that moves in contact with the panel guide 11 is rotatably attached to the tip of the shaft 23.

As shown in FIGS. 6 and 8, the engagement between the panel linking chain 3 and the pin 21 is rotatable within attachments 24 provided at predetermined intervals of the panel linking chain 3, and is movable in the thrust direction. This is done by inserting and engaging the
The panel 2 moves up and down integrally with the panel linking chain 3. The attachment 24 is provided with a hanging roller 25, which engages with the support rail 4 when the panel 2 is stored, and the support rail 4 suspends and supports the panel 2 in a folded state.

Next, the operation will be explained. In order to raise and lower the panel 2, when the panel drive means 13 is activated, its rotational driving force is applied to the interlocking chain 15, the interlocking sprocket 14, the main drive side rotating shaft 16, the second transmission sprocket 18, the transmission chain 19, and the first transmission sprocket. This is done by being transmitted to the panel drive sprocket 8 via the sprocket 17 and the driven rotation shaft 20, respectively.

That is, when the panel drive sprocket 8 is rotationally driven in the direction of the arrows in FIGS. 1 and 2 by the power transmission as described above, the panel connection chain 3 meshed therewith is rotated along the guide rail 1. As the panel connection chain 3 rises,
Each panel 2 in multiple upper and lower stages connected by the chain
will be raised sequentially. As a result, when the upper end of the panel 2 reaches the panel drive sprocket 8, the upper end of the panel 2 moves circularly along the pitch circumference of the panel drive sprocket 8 together with the panel linking chain 3, and the support rail Guided movement in direction 4. Further, at this time, the panel roller 22 attached to the lower end of the panel 2 is rotationally guided diagonally upward by the panel guide 11, and advances into the storage box 5 in a state in which lateral vibration is prevented.

In this way, the panel 2 that has moved in the storage direction within the storage box 5 smoothly leaves the movement path of the subsequent panel 2, so that the subsequent panel 2 is not hindered from rising.

Then, the suspension roller 25 of the panel 2 that has passed through the panel drive sprocket 8 in the storage direction moves onto the support rail 4, and the suspension roller 25 rolls on the support rail 4 due to its inclination. As a result, the panel 2 is automatically moved into the storage box 5 along the support rail 4 by its downward slope in a suspended state. At this time, on the panel entrance/exit side where the panel drive sprocket 8 first engages with the panel connection chain 3, a panel entrance/exit chain guide member 10 that extends so as to be able to guide the meshing direction is disposed, so that the panel connection chain 3 is reliably guided to a predetermined position on the panel drive sprocket 8. Furthermore, even if the panel connecting chain 3 and the panel drive sprocket 8 are abnormally engaged due to some unforeseen action, the panel storage side chain guide member 9 is placed on the panel storage side where the engagement ends. Since the panel connecting chain 3 is guided into contact with this panel storage side chain guide member 9, the panel connecting chain 3 is reliably separated from the panel driving sprocket 8, and the panel as described above is removed. 2
The storage operation is carried out smoothly.

Here, when storing the panels, the panel connecting chain 3 is placed in the storage box 5 together with the first panel 2 without being entangled by the chain tip guide rod 6.
When the panels 2 are folded and stored, the panels 2 are in a stored state in which the sides of each panel 2 are regularly adjacent to each other in a meandering manner, as shown by the two-dot chain line a in FIG.

Then, when storing each subsequent panel 2 by changing its direction from upward movement to horizontal movement toward the support rail 4, the panel connection chain 3 connecting the preceding panel 2 and the following panel 2 is connected to the first panel 2. A sagging part may occur as shown by the dashed line b in the figure, but
Since the side edge 9a of the panel storage side guide member 9 extends downward, the situation where the hanging portion meshes with the panel drive sprocket 8 is reliably prevented, and damage to the support rail 4 and damage to the panel 2 are prevented. Elevation and descent are not obstructed.

This series of operations is repeated every time the subsequent panel 2 reaches the vicinity of the support rail 4.

On the contrary, the above-mentioned drawing-out operation of the panel 2 is performed by reverse activation of the panel driving means 13.

That is, when the panel drive means 13 is reversely activated,
When the panel drive sprocket 8 is driven to rotate in the reverse direction, the panel linking chain 3 meshed with the sprocket 8 is let out, and each of the panels 2 is pulled out in sequence. At this time, in the vicinity of the panel driving sprocket 8, first, the side edge 9a and upper edge 9b of the panel storage side chain guide member 9
The panel linking chain 3 is reliably guided to a predetermined meshing position of the panel driving sprocket 8. Furthermore, the panel linking chain 3 is smoothly separated from the panel driving sprocket 8 by the other chain guide member 10 on the panel entrance/exit side.

In the process of lifting and lowering the panels 2 as described above, if the panels 2 are folded or jammed together within the guide rail 1, the panels 2
This can lead to an unfortunate situation where the machine stops working, and if left as is, it can lead to a major accident.

However, in this case, abnormal refraction occurs in the panel connecting chain 3, and when the chain slack detection device 7 detects the abnormal refraction, a major accident may occur due to mutual folding or clogging of the panels 2. can immediately respond to scandals.

As described above, according to this invention, during the panel raising and lowering operation process of a panel type shutter device, the panel connecting chain near the panel drive sprocket is connected to at least one of the panel storage side chain guide member or the panel entrance side chain guide member. Since contact is guided in a predetermined engagement direction or disengagement direction with respect to the panel drive sprocket by either one, irregular or harmful engagement of the panel linking chain with the panel drive sprocket can be prevented and reliably caused. This has the effect of improving the reliability of the panel type shutter device by making it possible to always perform smooth and efficient panel raising and lowering operations.
