[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a panel shutter for opening and closing an opening of a building by a shutter curtain configured by connecting a plurality of panels in series with a roller chain.

[0002]

[Prior art]

 A conventional panel shutter is provided with a pair of left and right guide rails standing upright on both sides of the opening for opening and closing the shutter, and a storage box arranged above these guide rails. The upper and lower panels are connected in series by roller chains on the left and right sides respectively, and the roller chains are meshed with the panel drive sprockets in the storage box. By the feed operation of the roller chain by the rotation drive, the panel is continuously transported along the guide rail in the vertical posture in the series posture and in the storage box in the horizontal posture in the parallel posture along the storage rail. It is supposed to do. In the panel side-by-side posture, the suspension rollers pivotally supported on the left and right sides of each panel are rotatably supported on the storage rails so that the panels can be suspended and stored.

Here, the storage rails in the conventional panel shutter are arranged inside brackets on both sides of the storage box, and extend horizontally from a position near the panel driving sprocket toward the panel storage direction. It is composed.

[0004]

[Problems to be solved by the device]

 The conventional panel shutter is configured as described above, and the storage rail that supports the roller for suspending the panel in a rollable manner is horizontally arranged in the storage box.Therefore, when the shutter is opened, the sprocket for driving the panel can be installed. The panel that passes through the panel storage direction side and is suspended by the storage rail via the hanging roller cannot be moved in the panel storage direction unless pushed by the subsequent panel. There is a concern that the panel storage operation in the panel parallel posture along the storage rail may not be smoothly performed, and there is a problem that reliability is lacked.

As a conventional shutter device of this type, for example, there is one disclosed in West German Patent Publication No. 270 3512, and in this shutter device, each of a plurality of panels (also referred to as slats) is disclosed. By connecting the lower end of the eye plate member to the left and right end faces with a pin, rotatably supporting the hanging roller on the upper end of the eye plate member, and connecting the roller chain to the roller shaft. However, since the panels are connected in series on both the left and right sides, there is a problem that the connection structure of the panels becomes very complicated.

In addition, as described above, the hanging roller pivotally supported on the upper end portion of the eye plate member is provided inside the roller chain (coupling with the panel driving sprocket) which is connected on the same axis as the hanging roller. Since it is located between the roller chain), the storage rails must be arranged so that they do not interfere with the roller chain that hangs down when the panel is stored. The space area for hanging the roller chain must be specially secured between them, which complicates the structure and makes the storage box large, which makes it impossible to make a compact storage structure. was there.

The present invention has been made to solve the above problems, and provides a dedicated space area for suspending a panel connecting chain (roller chain) that connects panels to each other in a panel parallel posture. It is possible to arrange the parts that do not need to be specially secured, and this makes it possible to make the storage box compact and have a compact storage structure, and also to store the panel that has passed the panel drive sprocket when the shutter is opened along the storage rail. It is an object of the present invention to provide a highly reliable panel shutter that can be automatically moved and moved to the direction side.

[0008]

[Means for Solving the Problems]

 A panel shutter according to the present invention comprises a pair of left and right guide rails arranged on both sides of a shutter opening / closing opening, a plurality of upper and lower panels that are opened and closed between the guide rails, and a shaft support on both left and right sides of the panel. The hanging roller, the panel connecting chain that connects the panels to each other on the left and right sides in a series, the storage box arranged above the guide rail, and the guide rail in the storage box. A panel driving sprocket that is axially supported upward and meshes with the panel connecting chain, and the panel hanging sprocket that is disposed in the storage box and passes through the panel driving sprocket toward the panel storage direction. In a panel shutter equipped with a storage rail for rotatably supporting and suspending and storing the aforementioned panels in a parallel state, The panel connecting chain is arranged outside the left and right end surfaces of the panel, the hanging roller is arranged further outside of the panel connecting chain, and the storage rail is installed from the vicinity of the panel driving sprocket to the panel. It is gradually inclined downward toward the storage direction.

[0009]

[Action]

 In the panel shutter according to the present invention, since the hanging roller is arranged further outside the panel connecting chain that is arranged outside the left and right end surfaces of each panel and connects the panels to each other, it is possible to suspend when the panels are in the parallel posture. The panel connecting chain can be hung inside the storage rail that rotatably supports the lowering roller, so that the storage rails can be attached to both sides of the storage box so as not to interfere with the hanging of the panel connecting chain. It can be mounted and arranged directly inside the bracket. Therefore, it is not necessary to secure a dedicated space area for suspending the panel connecting chain in the area of the panel parallel posture as in the conventional case, and accordingly, the storage box can be downsized and a compact storage structure can be realized. Moreover, since the storage rails are gradually inclined downward from the vicinity of the panel drive sprockets toward the panel storage direction, the panel drive sprocket passes through the panel storage direction during the shutter opening operation. The suspension rollers can be automatically rolled and run toward the inner side in the panel storage direction by the inclination of the storage rail, and therefore the panel storage operation is always performed smoothly.

[0010]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In the figure, 1 is a pair of left and right guide rails, and these guide rails 1 are composed of vertical guide rails standing upright on both sides of a so-called shutter opening / closing opening such as an entrance / exit of a building or a window.

Reference numeral 2 denotes a plurality of upper and lower panels that open and close between the guide rails 1, and these panels 2 are suitable for a rectangular frame 2a as shown in FIGS. 2 and 4 and 5. The face plate 2b is attached.

As shown in FIG. 3 and FIG. 4, pins (support shafts) 21 projecting outward from both end surfaces of the panel 2 are provided on both upper sides of the panel 2. Is connected to the panel connecting chain 3 composed of the above through a sleeve-like attachment 24 so as to be rotatable and movable in the thrust direction.

In this way, the plurality of panels 2 that move up and down between the two guide rails 1 are connected to each other by the pin 21 and the panel connecting chain 3 in series outside the both end surfaces of each panel 2. It is connected.

A hanging roller 25, which is located further outside the panel connecting chain 3, is rotatably attached to the pin 21 of each panel 2. Further, panel rollers 22 are rotatably supported on both sides of the lower part of each panel 2.

A storage box 5 is arranged above the guide rails 1. The storage box 5 is provided with vertical brackets 5a on both left and right sides, and is located above the guide rails 1 inside the brackets 5a. A pair of left and right panel driving sprockets 8 are pivotally supported, and the panel connecting chain 3 is meshed with these panel driving sprockets 8.

A storage rail 4 is disposed inside the bracket 5 a, and the storage rail 4 is located above the horizontal line passing through the axis of the panel drive sprocket 8 and between the bracket 5 a and the panel drive sprocket 8. Extending in the lateral direction from the side toward the panel storage direction, the panel storage direction side gradually and downwardly inclines, and rolls the suspension roller 25 of the panel 2 that has passed the panel drive sprockets 8 toward the panel storage direction. It is designed to be freely supported.

The descending end portion of the storage rail 4 is interrupted at a front position separated by a distance corresponding to the installation space of the opening / closing machine 13 from the depth end in the storage box 5, and the lowering of the storage rail 4 is performed. A stopper 4a (FIG. 1) is provided at the terminal end portion to prevent the hanging roller 25 rolling on the storage rail 4 from falling off.

In the above, the series of panels 2 are vertically moved in a straight line along the guide rails 1 by the feeding operation of the panel connecting chain 3 by the forward and reverse rotations of the panel driving sprockets 8 and the storage rails 4. It is designed to be continuously transferred along with the lateral movement in a parallel posture. In the parallel posture of the panels 2, the panel connecting chain 3 between the panels 2 hangs down inside the storage rail 4.

In such a panel shutter, an abnormal refraction of the panel connecting chain 3 located near a lower portion of the panel driving sprocket 8 is provided on a side portion near the upper end portion of the guide rail 1 extending in the storage box 5. A chain slack detecting device 7 for electrically detecting (slack) is provided.

In the vicinity of the panel drive sprocket 8 in the storage box 5, the panel connecting chain 3 is brought into contact with the panel drive sprocket 8 in an appropriate meshing direction or a meshing disengagement direction in the movement process of the panel 2. Chain guide members 9 and 10 for guiding are arranged.

In these chain guiding members 9 and 10, the panel housing side chain guiding member 9 arranged on the housing rail 4 side in the vicinity of the panel driving sprocket 8 projects from the inside of the bracket 5 a of the housing box 5. It has an upper edge 9b and a side edge 9a that wrap around the side of the panel driving sprocket 8.

More specifically, the upper edge 9b of the panel accommodating side chain guide member 9 is an inner member 9c located inside the addendum circle of the panel driving sprocket 8 and an outside member of the addendum circle. It has an outer member 9d located in the movement path of the panel connecting chain 3 that goes in and out of the box 5.

Further, the side edge 9a of the panel accommodating side chain guide member 9 is downwardly positioned on the accommodating rail 4 side of the panel driving sprocket 8 in a state of being spaced apart from and facing the tooth tips of the panel driving sprocket 8. It extends so as to prevent the hanging portion of the panel connecting chain 3 from being entangled and meshed with the panel driving sprocket 8.

The panel accommodating-side chain guiding member 9 is formed so as to be in contact with the panel connecting chain 3 so that the panel connecting chain 3 can be contact-guided to the panel driving sprocket 8 in the engaging direction, the engaging releasing direction, and the guide rail 1 direction. Has been done.

On the other hand, the panel inlet / outlet side chain guide member 10 arranged on the guide rail 1 side in the vicinity of the upper end side of the guide rail 1 includes an inner member 10 a located inside the addendum circle of the panel driving sprocket 8. , An outer member 10b located outside the tip circle and in the movement path of the panel connecting chain 3, and comes into contact with the panel connecting chain 3 to disengage the panel connecting chain 3 in the meshing direction. Direction and the guide rail 1 direction, the contact guide is formed.

In the above, at least one of the panel storage side chain guiding member 9 and the panel entrance / exit side chain guiding member 10 constitutes a chain / sprocket guiding device.

A panel guide 11 is provided near the panel entrance of the storage box 5 for smoothly guiding the panel rollers 22 at the bottom of each panel 2 in the panel storage direction and the panel feeding direction.

Further, an opening / closing device 13 is arranged in the depth space portion inside the storage box 5. Here, in the storage box 5, the descending end of the storage rail 4 is interrupted at a front position separated from the depth end of the storage box 5 by a distance corresponding to the installation space of the switch 13, so that the storage rail 4 is stopped. The opening / closing device 13 is arranged by utilizing a depth space region in the storage box 5 in which the storage box 5 does not extend.

As shown in FIG. 1, the opening / closing machine 13 integrally has a mounting base 13a, and long and downward long slots 13b are provided at upper and lower portions on both sides of the mounting base 13a. .

Then, in the inner space area of the storage box 5, the opening / closing device 13 is attached to the bracket 5a on one side thereof. At the time of attachment, the opening / closing device 13 is attached to the long hole 13b of the attachment base 13a of the opening / closing device 13. The mounting base 13a is fixed to the bracket 5a by inserting the bolt 28 and screwing and tightening the nut 29 on the bolt 28. Therefore, by loosening the nut 29, the mounting position of the switch 13 can be adjusted in the vertical direction by an amount corresponding to the length of the elongated hole 13b.

The switch 13 has an output sprocket 130 as shown in FIG. 1, and an interlocking sprocket 14 is interlocked with the output sprocket 130 via an interlocking chain 15.

The interlocking sprocket 14 has a first transmission sprocket 17 coaxially and is rotatably attached to the bracket 5 a via a bearing 30. As shown in FIG. 1, the bearing body 30 is fitted and mounted in a notch 5b provided in the bracket 5a so as to be positionally adjustable. Therefore, the rotation shaft connecting the interlocking sprocket 14 and the first transmission sprocket 17 can be adjusted in space between the rotary shaft and the panel driving sprocket 8.

The panel driving sprocket 8 has a second transmission sprocket 18 coaxially therewith, and an endless transmission chain 19 is meshed and wound around the second transmission sprocket 18 and the first transmission sprocket 17. Thus, the rotation output of the switch 13 is transmitted to the sprocket 8 for driving the panel.

Here, the opening / closing device 13, the interlocking sprocket 14 and the first transmission sprocket 17 are substantially the same as the panel 2 in the storage position suspended in the storage rail 4 in the inner space area in the storage box 5. They are arranged in parallel in the vertical direction.

With such an arrangement, the installation space of the switch 13 and the power transmission sprocket (the interlocking sprocket 14 and the first transmission sprocket 17) in the storage box 5 can be minimized. Therefore, it is not necessary to make the installation space particularly large, and the installation space of the storage box 5 is reduced as compared with the case where the switch 13 is externally attached to the storage box 5, and the restriction on the installation work is limited. Can be greatly eased.

A chain tip guide rod 6 parallel to the storage rail 4 is arranged at a position above the storage rail 4 in the storage box 5 so as to be separated therefrom. The chain tip guide rod 6 is arranged by effectively utilizing an upper space between the bracket 5a and both end surfaces of the panel 2 suspended by the storage rail 4.

A free end portion (end side link portion) 3a of a panel connecting chain 3 that meshes with a panel driving sprocket 8 and extends in the panel storage direction is movably moored to the chain tip guide rod 6. There is.

As a result, when the panel 2 is moved up and down, the free end 3a of the panel linking chain 3 moves along the chain tip guide rod 6, so that it first moves onto the storage rail 4 during the panel storage operation. The length from the pin 21 of the panel 2 to the free end 3a of the panel connecting chain 3 can be shortened.

Therefore, the free end side of the panel connecting chain 3 does not greatly loosen particularly when the panel is housed, and the entanglement of the panel connecting chain 3 during the panel ascending / descending operation can be reliably prevented.

Further, since the free end portion 3a of the panel connecting chain 3 is always moored to the chain tip guide rod 6 as described above, the panel connecting chain 3 is detached from the panel driving sprocket 8 when the panel is extended. Nonetheless, safety and reliability will be greatly improved.

Further, as described above, the chain tip guide rod 6 arranged above the storage rail 4 has the panel connecting chain 3 connecting the panels 2 in the parallel posture suspended on the storage rail 4 in the U-shape. Since it does not hinder the bending and hanging in a letter shape, there is no need to provide a special space for arranging the chain tip guide rod 6 in the storage box 5, and thus a compact and compact structure can be achieved.

Next, the operation will be described. When the switch 13 is activated in the shutter opening direction, the rotational driving force from the output sprocket 130 via the interlocking chain 15 is the interlocking sprocket 14 → first transmission sprocket 17 → transmission chain 19 → second transmission sprocket 18 → By being transmitted to the panel drive sprocket 8, the panel drive sprocket 8 is rotationally driven in the clockwise direction in FIG.

As a result, the panel 2 between the guide rails 1 is pulled up via the panel connecting chain 3 meshing with the panel driving sprocket 8. When the upper end of the panel 2 reaches the panel drive sprocket 8 due to the pulling up, the upper end of the panel 2 circularly moves along with the panel connecting chain 3 along the pitch circumference of the panel drive sprocket 8 and the storage rail 4 moves. It is guided and moved in the direction.

At this time, the panel roller 22 at the lower portion of the panel 2 is guided obliquely upward by the inclined guide portion 11a of the panel guide 11 and advances in the storage box 5 in the depth direction (panel storage direction).

In this way, the upper end portion of the panel 2 that has moved upward between the guide rails 1 makes an arc movement toward the storage rail 4 side (panel storage direction side) along the tooth tips of the panel drive sprocket 8. At this time, the panel roller 22 is guided obliquely upward by the panel guide 11, so that the panel 2 is maintained in the vertical posture in the lateral shake prevention state when the panel drive sprocket 8 is passed through in the panel storage direction. Moving.

Then, in the panel 2 that has passed through the panel drive sprocket 8 in the panel storage direction, the hanging rollers 25 on both upper sides of the panel 2 move onto the storage rail 4. At this time, the suspending roller 25 rolls on the storage rail 4 by its inclination, so that the panel 2 automatically descends along the storage rail 4 in the suspended state in the parallel posture by its descending inclination. Move in.

Then, when the suspension roller 25 of the panel 2 that first migrates onto the storage rail 4 reaches the end of the descending slope of the storage rail 4, the suspension roller 25 is suspended from the storage rail 4. It comes into contact with a stopper 4a provided at the descending end portion and is prevented from falling off from the storage rail 4.

In this way, after the first panel 2 reaches the lower end of the storage rail 4, the subsequent panels 2 are sequentially fed, so that the panels 2 sequentially transferred to the storage rail 4 are adjacent to each other. It is suspended and stored in a hanging state in parallel.

In the above, when the panel 2 is transferred from the vertical movement in the serial posture along the guide rail 1 to the horizontal movement in the parallel posture along the storage rail 4, the sprocket 8 for driving the panel is connected to the chain 3 for linking the panels. Since the panel inlet / outlet side chain guide member 10 extending so as to be able to guide the engagement direction is arranged on the panel inlet / outlet side that first meshes with the panel inlet / outlet side, the panel drive side of the panel inlet / outlet side chain guide member 10 The panel connecting chain includes an inner member 10a located inside the addendum circle of the sprocket 8 and an outer member 10b located outside the addendum circle and within the movement path of the panel connecting chain 3. 3 is surely guided in a predetermined direction with respect to the sprocket 8 for driving the panel.

Further, even if the panel connecting chain 3 and the panel driving sprocket 8 are abnormally engaged with each other due to some unexpected action, the panel accommodation side chain guide is provided on the panel accommodation side where the above engagement is completed. Since the member 9 is arranged, the panel accommodating side chain guiding member 9 has the inside of the tip circle of the panel driving sprocket 8 and the upper side of the horizontal line passing through the axis of the panel driving sprocket 8. The positioned inner member 9c and the inner axis of the panel driving sprocket 8 are located in the movement path of the panel connecting chain 3 that moves in and out of the storage box 5 outside the addendum circle of the panel driving sprocket 8. With the outer member 9d positioned above the horizontal line passing through, the panel connecting chain 3 is properly engaged with the sprocket 8 for driving the panel. Since the guide is brought into contact with the disengagement direction and the guide rail 1 direction, the panel connecting chain 3 is reliably disengaged from the panel driving sprocket 8 and the panel 2 is smoothly stored.

Here, the functions and effects of the inner member 9c and the outer member 9d will be described in more detail. Since the panel connecting chain 3 comes into contact with each other at two portions, the inner member 9c located inside the addendum circle of the panel driving sprocket 8 and the outer member 9d located outside the addendum circle. The contact area is greatly expanded, and the disengagement is performed with certainty and efficiency, and the panel connecting chain 3 and the panel storage side chain guiding member 10 concentrate unreasonable force generated at the time of disengagement. Since it does not occur, unnecessary damage is unlikely to occur and its life is extremely long. In particular, since the contact between the two always occurs at the time of the above reverse activation, such an effect is extremely important.

Further, since the inner member 9c comes into contact with the root portion of the meshing position of the panel connecting chain 3 meshing with the panel driving sprocket 8 and releases the mesh, the mesh releasing effect is extremely high. It is remarkable.

Further, since the inner member 9c and the outer member 9d are both located above the horizontal line passing through the axis of the panel driving sprocket 8, the panel driving sprocket 8 of the panel connecting chain 3 is The disengagement can be performed extremely efficiently and effectively. However, since the inner member 9c and the outer member 9d are located near the starting end of the storage rail 4 when viewed from the side as shown in FIG. 1, it is extremely effective timing for releasing the meshing of the panel connecting chain 3. It can be carried out.

When the panel is stored, the roller chain 3 moves into the storage box 5 together with the first panel 2 without being entangled by the chain tip guide rod 6, and when the panel 2 is folded and stored, the roller chain 3 is shown in FIG. As shown by the dotted line (a), the panel 2 is regularly hung in a U-shape along the side surface of each panel 2.

In this way, when each panel 2 changes its direction from the upward vertical movement in the series posture along the guide rail 1 to the horizontal movement in the parallel posture along the storage rail 4, the initial horizontal movement in the parallel posture is performed. In the above, the roller chain 3 connecting the preceding panel 2 and the following panel 2 hangs down. This hanging part is guided downward along the side edge 9a of the panel housing side chain guiding member 9, so that the roller chain It is possible to reliably prevent the hanging portion of 3 from being entangled with the sprocket 8 for driving the panel, so that the storage rail 4 is not damaged and the vertical movement of the panel 2 is not hindered. This series of operations is repeated each time the subsequent panel 2 reaches the vicinity of the storage rail 4.

Next, when the opening / closing switch 13 is started in the reverse rotation from the above-mentioned panel housed state, the rotation output thereof drives the panel drive sprocket 8 to rotate counterclockwise in FIG. 1 to drive the panel drive. The panel 2 on the storage rail 4 is sequentially pulled out in the feeding direction through the roller chain 3 meshing with the sprocket 8 for use.

At this time, in the vicinity of the panel driving sprocket 8, first, the panel connecting chain 3 is moved to a predetermined meshing position of the panel driving sprocket 8 by the side edge 9a and the upper edge 9b of the panel storage side chain guiding member 9. Be sure to be guided. Further, the panel connecting chain 3 is smoothly separated from the panel drive sprocket 8 by the other panel entrance / exit side chain guide member 10.

That is, the panel connecting chain 3 is composed of two parts, an inner member 10a located inside the addendum circle of the panel driving sprocket 8 and an outer member 10b located outside the addendum circle. Since they come into contact with each other, the contact area is greatly expanded, and the disengagement is extremely surely and efficiently performed, and the panel connecting chain 3 and the panel inlet / outlet side chain guiding member 10 are forced to exert an unreasonable force at the time of disengagement. Since it is not concentrated in one place, unnecessary damage is unlikely to occur and its life is extremely long. In particular, the contact between the two always occurs at the time of the reverse activation, so such an effect is extremely important.

Further, since the inner member 10a comes into contact with the root portion of the meshing position of the panel connecting chain 3 meshing with the panel driving sprocket 8 and releases the mesh, the mesh releasing effect is extremely remarkable. is there.

In the process of raising and lowering the panel 2 as described above, if the panels 2 are folded or clogged in the guide rail 1 by any chance, the panel 2 becomes an unusable situation and cannot be left as it is. It causes a big accident.

However, in this case, abnormal refraction occurs in the panel connecting chain 3, and the chain slack sensing device 7 senses the extraordinary refraction, which causes a large amount of folding or clogging between the panels 2. It can respond immediately to scandals such as accidents.

[Effect of device]

 As described above, according to the present invention, the hanging roller is arranged further outside the panel connecting chain that is arranged outside the left and right end surfaces of each panel and connects the panels to each other. Supports the hanging rollers to roll freely when the panel is in parallel position.The panel connecting chain can be hung inside the storage rail. Therefore, the storage rail is stored so as not to interfere with the hanging of the panel connecting chain. It can be installed directly inside the brackets on both sides of the box, so that in the panel parallel posture area, it is not necessary to separately secure a dedicated space area for hanging the roller chain as in the conventional case, and Therefore, there is an effect that the storage box can be downsized and the storage structure can be made compact.

In particular, in this invention, since the storage rail is gradually inclined downward from the vicinity of the panel drive sprocket toward the panel storage direction, the panel drive sprocket is moved in the panel storage direction during the shutter opening operation. The panel hanging roller that has passed to the side can be automatically rolled and run toward the inner part in the panel storage direction by the inclination of the storage rail, so that the panel storage operation is always smooth. That is, there is an effect that the reliability of the shutter is improved.
