Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a panel shutter device that opens and closes an opening by lifting and suspending a shutter made by vertically connecting and suspending a plurality of panels. be.

[Prior Art] Generally, a panel shutter device is constructed by connecting and suspending both side edges of a plurality of panels in a series with roller chains, and the shutter is configured to rotate in the forward and reverse directions of an induction sprocket that engages with the roller chain. The openings are closed and opened in conjunction with each other as they are lifted up, but when hanging, the running rollers installed on both sides of each panel are guided by guide rails erected on both sides of the opening, and each panel is placed on a vertical plane. The panels are arranged in a shape to close the opening, and when lifted, each panel is sequentially fed into a storage rail provided in the front-rear direction above the opening and suspended in parallel by the traveling rollers to open the opening. There is.

However, in conventionally known panel shutters, the positional relationship between the running rollers and the roller chain is such that the running rollers are placed inside the hanging part of the roller chain, so the roller chain between the panels is not easily moved during storage. It is necessary to position the storage rail at a distance from the bracket so as not to interfere with the hanging, and to secure space for the roller chain to hang between both members. It is no longer possible to directly support the storage rail on the bracket, so the storage rail must have a flat plate structure that is spaced apart from the bracket and supported by a drive shaft.
In addition to complicating the configuration, a special space must be provided outside the roller chain to accommodate opening/closing members such as a drive sprocket and bearing members for rotating the induction sprocket in the forward and reverse directions. This has the drawback that the width of the storage case becomes large and a compact storage structure cannot be achieved, and furthermore, the roller chain hanging between each panel is close to the flat storage rail. It lacked practicality, as it produced a rubbing noise with the storage rail when the panel was moved.

[Problems to be Solved] The present invention has been made in view of the actual situation of the conventional panel shutter device described above, and is intended to improve the above-mentioned problems. can be mounted on a bracket without having to secure special space, and the entire storage case has a simple configuration and is lightweight and compact. It is an object of the present invention to provide a panel shutter device that can secure a housing configuration that allows easy replacement and repair of consumable parts such as a chain.

[Means for Solving the Problems] In order to solve the above problems, the technical means adopted by the present invention is to provide running rollers outside the left and right end surfaces of a plurality of panel bodies, and further to move each panel body to The roller chain is connected in a suspended manner by a roller chain provided outside the left and right end surfaces, and the roller chain is meshed with an induction sprocket that is pivotally supported on the left and right brackets, and is linked to the forward and reverse rotation of the induction sprocket. By the feeding operation, the panel body is vertically moved in a serial position along the guide rails provided in the vertical direction on the left and right sides of the opening, and horizontally in a parallel position along the storage rails provided in the front and rear direction of the bracket. In a panel shutter that is configured to be moved and transferred, the storage rail may include:
It has a vertical surface for mounting a bracket and a rolling surface of the running roller, and the rolling surface of the running roller is faced between the bracket and the roller chain meshed with the induction sprocket, and the lower surface of the rolling surface is A space is formed below, and the rolling surface of the traveling roller is guided by the outer locus of movement of the guiding sprocket, which is disposed outside the left and right end surfaces of the panel body, to the outside of the roller chain. The panel bodies are stored in a parallel position by rolling arranged running rollers, and when the panels are in a parallel position, a roller chain between each panel is made to hang inward from the storage rail. It is something to do.

[Embodiment] The structure of the present invention will be described based on an embodiment shown in the drawings. Reference numeral 1 denotes a panel shutter provided in an opening of a building, and the panel shutter 1 is arranged in a vertical direction. It is constructed by connecting and pivoting a plurality of panel bodies 2, 2... disposed at a predetermined interval to a roller chain 4 in a series through support shafts 3 disposed on the upper side of both left and right ends thereof. has been done.
Each panel body 2 is formed into a long plate shape that is long in the horizontal direction, and a protruding strip 2a is formed on the upper edge thereof over the entire length in the longitudinal direction, and a protruding strip 2a is tightly fitted on the lower edge. A groove 2b is formed. Guide rails 5 are provided vertically on both left and right edges of the opening, and the panel shutter 1 is raised and lowered while being guided by the guide rails 5 in a vertically hanging state. A storage case 6 is provided above the guide rail 5, and the inside surface of the bracket 6' of the storage case 6 has a storage rail 6a facing horizontally and laterally.
has been installed. The storage rail 6a has a vertical surface for mounting a bracket and a running roller rolling surface,
A running roller rolling surface is exposed between the bracket 6' and the roller chain 4 meshed with the guide sprocket 7, and a space is formed below the lower surface of the rolling surface.

Reference numeral 7 denotes an induction sprocket disposed above the upper end of the guide rail 5, and the induction sprocket 7 is pivotally supported inside the bracket 6' via a drive shaft 7a that rotates forward and backward by a drive mechanism (not shown). The opening is opened and closed by lifting and suspending the roller chain 4 that meshes with the induction sprocket 7. The induction sprocket 7 located above the guide rail 5 is adapted to mesh with the roller chain 4 at a position that is biased towards the storage rail 6a side from the upper extension line of the guide rail 5. An inclined transfer rail 8 is provided between the upper end and the induction sprocket 7.
is formed.

9 is a running roller, and the running roller 9 is
The guide sprocket 7 is disposed outside the roller chain 4 so as to be moved along the outside movement locus of the induction sprocket 7, which is placed outside the end faces of the panel bodies 2, 2..., and roll on the rolling surface of the storage rail 6a. . Therefore, in the panel parallel posture when the panels 2, 2 are stored, the roller chain 4 between each panel 2, 2...
The panels 2, 2, . . . are stored by hanging down inside the storage rail 6a.

[Operation] Next, the operation of the present invention configured as described above will be explained.

First, the opening operation of the panel shutter 1 is performed by rotating the induction sprocket 7 in the forward direction and lifting the roller chain 4, so that the panel bodies 2, 2, etc. arranged in series in the vertical direction are successively arranged in a series starting from the topmost one. This is done by ascending from the guide rail 5 to the storage rail 6a side via the transfer rail 8, and storing them in parallel in the horizontal direction within the storage case 6.
In this case, the panel body 2 that rises due to the rotation of the induction sprocket 7 is transferred from the upper end of the guide rail 5 to the storage rail 6a side via the inclined transfer rail 8. The lower panel body 2 will not collide. Therefore, even if the opening operation is performed at high speed, it is possible to prevent the following lower panel body 2 from colliding with the upper panel body 2, and a smooth opening operation can be performed at high speed.

On the other hand, the closing operation of the panel shutter 1 is achieved by rotating the induction sprocket 7 in the opposite direction and suspending the roller chain 4, which connects the storage rail 6a to the guide rail 5 side via the transfer rail 8 in the reverse operation. This is done by being sent. In this case, the suspended roller chain 4 is pivotally connected to a support shaft 3 provided at the upper edge of the panel 2, so that the panel 2 receives wind pressure from the lintel when the panel 2 is fed out. Also, since the inertial weight of the swing is increased and the swing caused by the wind pressure is reduced, the transfer to the vertical guide rail 5 is reliably performed, and high-speed closure can be coped with.

By the way, in the process of the above-mentioned series of opening and closing operations, especially in the present invention, the storage rail 6a is formed by a vertical surface for mounting the bracket and a rolling surface of the running roller, and is meshed with the bracket 6' and the induction sprocket 7. A running roller rolling surface is faced between the roller chain 4 and a space is formed below the lower surface of the rolling surface. The traveling rollers 9 arranged on the outer side of the roller chain 4 are moved along the outer movement trajectory of the guide sprocket 7 arranged on the outer side of the end face, and the panel bodies 2 are housed in a parallel posture. In the parallel posture of the panels, the roller chain 4 between each panel is made to hang inward from the storage rail 6a, so that the rolling of the storage rail 6a on which the traveling rollers 9 disposed outside the roller chain 4 rolls. Since a space is formed between the bracket 6' and the roller chain 4 in the lower surface area, when storing the panels, the roller chain 4 between each panel can be hung across the space, Therefore, it is not only possible to prevent the friction noise between the roller chain 4 and the bracket 6' when the panel is moved, but also to prevent the formation of a separate space outside the roller chain 4 as in the conventional case. It can be used effectively to arrange opening/closing members such as drive sprockets and drive chains, and the width of the storage case can be reduced to make it more compact, eliminating the need for installations with limited storage space. We can respond even in the field.

Furthermore, even when the panels 2 are connected by the roller chain 4, the running rollers 9 can be rolled onto the rolling surface of the running rollers of the storage rail 6a from the base end side, the terminal end side, or an intermediate portion of the storage rail 6a. Therefore, even within the narrow enclosed storage case 6, the panel hanging work can be carried out without being hindered by the roller chain 4 hanging between the panels 2, 2... Even when replacing consumables such as the traveling rollers 9 and the roller chain 4, the panels can be easily replaced with the panels suspended.

In the above embodiment, the transfer path is configured as an inclined transfer rail 8, but the present invention is not limited to this, and as shown in FIG. An inclined transfer path may be formed between the upper end and the guide sprocket 7, and as shown in FIG. A rail 11 may be provided, and the following lower panel body 2 may be moved outwards with respect to the upper panel body 2 that ascends on the same upward trajectory as the guide rail 5, so that the structure is as inconsistent as possible. As shown in the figure, an auxiliary sprocket 12 may be provided to form an inclined transfer path.

[Effects of the Invention] In short, the present invention provides running rollers outside the left and right end surfaces of a plurality of panel bodies, and further suspends each panel body by a roller chain provided outside the left and right end surfaces. connected to the letter of intent,
The roller chain is engaged with an induction sprocket that is pivotally supported on the left and right brackets, and by feeding the roller chain in conjunction with the forward and reverse rotation of the induction sprocket, the panel body is installed in the vertical direction to the left and right of the opening. In the panel shutter, the storage rails include vertical movement in a serial position along a guide rail and lateral movement in a parallel position along storage rails provided in the front-rear direction of the bracket. It has a vertical surface for mounting a bracket and a rolling surface of the running roller, and the rolling surface of the running roller is faced between the bracket and the roller chain meshed with the induction sprocket, and the lower surface of the rolling surface is A space is formed below, and the rolling surface of the traveling roller is guided by the outer locus of movement of the guiding sprocket, which is disposed outside the left and right end surfaces of the panel body, to the outside of the roller chain. The arranged traveling rollers are rolled to allow the panel bodies to be stored in a parallel position, and when the panels are in the parallel position, the roller chain between each panel is made to hang inward from the storage rail, so that the following can be achieved. This produces particularly remarkable effects.

The storage rail can be easily installed and supported directly on the inner wall of the bracket.
A space is formed between the bracket and the roller chain in the lower surface area of the rolling surface of the storage rail on which the traveling rollers placed outside the roller chain roll, so when storing the panel, the space must be The roller chain can be hung between each panel separately, and therefore, there is no need to form a separate space further outside the roller chain as in the conventional case, and the friction between the roller chain and the bracket when the panels are moved can be prevented. Not only can noise be prevented, but the space can be used effectively to arrange opening/closing members such as drive sprockets and drive chains, and the width of the storage case can be reduced to make it more compact.
It can be used even in sites where construction with restricted storage space is required.

Even when each panel is connected by a roller chain, the running roller can be rolled onto the rolling surface of the running roller of the storage rail from the base end, end side, or intermediate part of the storage rail. Even in a narrow enclosed storage case, panels can be hung without being hindered by the roller chains hanging between each panel, and it is also convenient for replacing consumables such as traveling rollers and roller chains. Even if the panel gets hot, it can be easily replaced while the panel is suspended.
