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.In particular, the panel storage operation is always smooth. This invention relates to a panel type shutter device.

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.

This idea was made to solve the above problem, and it is possible to constantly move the panel smoothly in a predetermined storage direction or payout direction while the panel is moving up and down along the guide rail. ,
To provide a panel type shutter device capable of reliably and smoothly moving a panel in a predetermined panel storage direction or payout direction in a storage box above a guide rail without causing the panel to oscillate laterally.

In order to achieve the above object, the shutter device of this invention has a plurality of upper and lower panels connected by a panel linking chain that meshes with a panel drive sprocket arranged in a storage box above the guide rail, and that moves up and down along the guide rail. A guide protrusion is provided at the lower part of the panel of the step, and the lower guide protrusion of the panel is provided near the entrance of the storage box when the upper end of the panel reaches the vicinity of the panel drive sprocket. A panel guide is arranged to guide the lower part of the panel in the same predetermined movement direction as the upper part by slidingly engaging the panel.

In the shutter device of this invention, when the upper end of the panel reaches the vicinity of the panel drive sprocket when the panel moves up and down, the lower guide protrusion of the panel slides into engagement with the panel guide in the storage box. However, since the lower part of the panel is guided in the same predetermined moving direction as the upper part by the panel guide, the lower part of the panel can always be moved in the predetermined storage or unwinding direction within the storage box without causing any sideways movement. It can be moved reliably and smoothly, improving the performance of panel type shutter devices.

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 arranged on both sides of a so-called shutter opening/closing opening such as an entrance/exit of a building or a window.A storage box 5 is arranged above the guide rail. 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 gently downward toward the panel storage direction from the vicinity of the panel drive sprocket 8 which is engaged with 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 figure, 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 during the storage operation of the panel 2.
moves, and the panel connecting chain 3 does not hang down and get tangled.

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 disposed near the panel drive sprocket 8 on the support rail 4 side and guides the panel linking chain 3 into contact with the panel drive sprocket 8 in a predetermined engagement direction and disengagement direction. The combination 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 and the disengagement direction near the upper end side of the guide rail 1 allows the chain A sprocket engagement device is constructed.

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

This panel guide 11, as shown in the first diagram,
It is formed to be inclined diagonally upward in the storage box 5.

On the other hand, a lower guide roller (lower guide protrusion) 22 is attached to the lower part of each panel 2 for detachably slidingly engaging with the panel guide 11.

Here, the related functions of the panel guide 11 and the lower guide roller 22 will be explained.
When the upper part of the panel 2 reaches the vicinity of the panel driving sprocket 8 during the raising and lowering operation of each panel 2, the lower guide roller 2 of the panel 2
2 is slidably engaged with the panel guide 11, and the lower guide roller 22 is slidably engaged with the panel guide 11 by the panel guide 11.
is guided in the same predetermined moving direction as the upper part of the panel 2.

The panel connecting chain 3 is shown in FIGS. 1 and 3 (the double-dashed chain line is actually located at a symmetrical position with respect to the panel axis from the illustrated position, but is shown at the opposite position for convenience of the drawing). They are arranged along the panel guide 11 as shown in FIG. The tip of the panel connecting chain 3 is loosely fitted into the chain tip guide rod 6 as described above.

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 protruded 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. At about the same time, the above panel 2
The lower guide roller 22 is slidably engaged with the panel guide 11, is guided to rotate 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, the panel connection chain 3 and the panel drive sprocket 8
If they are abnormally engaged, the panel connecting chain 3 will be guided into contact with the panel entrance/exit side chain guiding member 10 near the panel driving sprocket 8. The panel 2 is reliably removed from the panel 2, and the above-described storage operation of the panel 2 is smoothly performed.

Here, when storing the panel, the panel connecting chain 3 moves into the storage box 5 together with the panel 2 without being entangled with the chain tip guide rod 6, and when the panel 2 is folded and stored, it is shown in FIG. As shown by the dashed dotted lines, the panels 2 are in a stored state in which their side surfaces are regularly adjacent to each other in a meandering manner.

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, the panel connecting chain 3 is smoothly separated from the panel driving sprocket 8 by the other panel entrance/exit side chain guiding member 10.

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. Furthermore, since the lower guide roller 22 of the panel 2 is guided in the direction of the guide rail 1 by the panel guide 11, the panel 2 is guided along a predetermined moving path without lateral wobbling.

Therefore, according to this invention, the movement of raising and lowering the panel 2 is always performed reliably and smoothly, and
Since the direction of movement of the panel 2 and the direction of the force acting on the panel 2 in its lifting and lowering operations can be approximately matched, the force applied can be used extremely efficiently as the force for opening and closing the panel 2, and as described above, the force can be used smoothly and reliably. The panel guide 11 and the lower guide roller 22 of the panel 2 allow the panel 2 to be stored and extended very reliably.

As described above, according to this invention, when the upper end of the panel reaches the vicinity of the panel drive sprocket during the panel lifting and lowering process of the panel type shutter device, the lower guide protrusion of the panel moves into the storage box. Slidingly engages the panel guide,
Since the lower part of the panel is guided in the same predetermined movement direction as the upper part by the panel guide, the lower part of the panel can always be reliably and reliably moved in the predetermined storage or delivery direction without causing any sideways movement within the storage box. It can be moved smoothly and the performance of the panel type shutter device is improved.
