[Detailed description of the device] [Industrial applications]

In this invention, a plurality of upper and lower panels that are vertically driven so that they can be transferred and stored in the upper panel storage box along the guide rails standing upright on both sides of the opening for opening and closing the shutter are mounted on the support rails in the panel storage box. The present invention relates to a panel support device for a panel shutter in which suspension means for suspending and suspending is improved.

[Prior art]

FIG. 8 is a schematic front view of a conventional panel shutter, FIG. 9 is an enlarged sectional view of FIG. 8A, FIG. 10 is an enlarged sectional view of a panel storage box portion in FIG. 8, and FIG. It is an expanded sectional view showing a meshing state of a sprocket and a chain in a panel storage box. First, in FIG. 8 and FIG. 9, 1 is a pair of left and right guide rails which are arranged on both sides of the opening for opening and closing the shutter and stand upright. (Panel fitting engagement part)
And a U-shaped member having an integral structure. On the upper part of the guide rail 1, as shown in FIGS. 8 and 10, a panel storage box (hereinafter, simply referred to as a box) 2 is arranged. Inside the box 2, a sprocket 3 for driving a panel located above the entrance and exit, and a support rail 7 for suspending and storing a panel in which the front short side is located near the upper part of the sprocket 3 and the rear end side is gradually inclined downward. And the above sprocket 3
Each of the panel opening / closing driving means M for driving the forward and reverse rotations of the is arranged. The guide rail 1 is attached to the sprocket 3.
The support rail 7 in the box 2 is moved up and down within the box 2.
A chain 4 that can be moved to the side is meshed. The chain 4 connects the upper and lower panels 5 adjacent to each other in the vertical direction between the guide rails 1. Here, a means for connecting the chain 4 and the panels 5 will be described. The panel mounting portion of the chain 4 is shown in FIGS.
As shown in the figure, a long pin P that doubles as a link pin is provided that penetrates the chain link connecting portion. A guide roller R that moves to the support rail 7 when the panel is housed, which will be described later, is rotatably attached to one end of the long pin P. The other end of the long pin P is connected to each of the panels 5
Are connected to both upper sides (inside both ends of the upper frame) through pin brackets 6. Therefore, the upper and lower sides of each of the panels 5 are connected to each other by the chain 4 via the long pins P. In other words, the long pins P are located at both upper ends of each panel 5, project outward in the extension direction from the both ends, penetrate the link connecting portion of the chain 4, and the guide roller R rotates on the projecting end shaft portion. It is installed freely. Then, as described above, the both side portions of the upper and lower panels 5 connected to each other by the chain 4 that meshes with the sprocket 3 are the ninth
As shown in the drawing, the guide rails 1 are fitted and engaged in the guide rails 1 so as to be able to move up and down. Therefore, the guide rails 1 house the chain 4, the long pin P, and the guide roller R so that they can be moved up and down. For this reason, as shown in FIG. 9, the guide rail 1 is of a size having a depth dimension H1 corresponding to the protruding length L1 of the long pin P on both upper sides of each panel 5. . Next, the operation will be described. When the panel opening / closing drive means M is started in the panel storage direction in the shutter closed state in which the upper and lower panels 5 are extended between the left and right guide rails 1, the sprocket 3 rotates clockwise in FIG. As the chain 4 is driven and wound up, the panels 5 sequentially enter the box 2. Then, in the panel 5 that has passed through the sprocket 3, the guide rollers R on both upper sides of the panel 5 move onto the support rail 7. Since the rear end side of the support rail 7 is gradually inclined downward, the guide roller R transferred onto the support rail 7 rolls downward due to the weight of the panel 5. As a result, the panel 5 that has entered the box 2 as described above is stored by being suspended in the adjacent hanging state on the support rail 7 via the guide rollers R on both upper sides thereof. Further, when the panel opening / closing drive means M is reversely activated from such a panel storage state, the sprocket 3 is rotationally driven in the counterclockwise direction, so that the above-mentioned panels 5 are both guide rails 1 via the chain 4. The guide rails 1 are sent out to close each other.

[Problems to be solved by the device]

The conventional panel shutter is configured as described above, and the guide roller R is attached to the tip end shaft portion of the long pin P connecting the chain 4 and the panel 5 as a panel suspension means on the support rail 7 when the panel is stored. Therefore, the protrusion length L1 of the long pin P must be increased by the mounting dimension of the guide roller R, which causes various problems. That is, as described above, the long pin P having the long protruding length L1 is
In particular, since a large moment is generated during suspension on the support rail 7, the long pin P has to have a large diameter to withstand this moment. When the long pin P has a large diameter, the chain 4 itself also has a large link structure. However, there is a problem that the sleeve size of the panel shutter becomes large. Further, even for the guide rail 1, it is necessary to use a guide rail 1 having a depth dimension H1 corresponding to the protruding length L1 of the long pin P. Therefore, the guide rail 1 is also enlarged. There were also problems. The present invention has been made to solve the above-mentioned problems, and it is possible to shorten the long pin connecting the panel and the chain, which can reduce the diameter of the long pin and also make the depth of the guide rail shallow. It is an object of the present invention to provide a panel suspension device for a panel shutter that can reduce the size of the rail and thus reduce the sleeve dimension of the panel shutter.

[Means for Solving the Problems]

The panel suspension device of the panel shutter according to this invention is
Upper and lower panels of a plurality of upper and lower panels that are engaged by engaging a pair of left and right guide rails that stand upright on both sides of the opening for opening and closing the shutter so as to be able to move up and down, and chains for connecting the panels to each other. Connected by long pins located on both sides, and in the vicinity of the long pin in the chain, project along a direction orthogonal to the long pin,
A suspension for axially supporting a panel for suspending the panel by shifting to the support rail in the panel storage box when the panel is stored.

[Action]

In the panel suspension device of the panel shutter in this invention, the long pin connecting the panel and the chain does not have a guide roller for hanging the panel as in the conventional case, and the long pin connects the panel and the chain. For this reason, the long pin has a shorter protruding length from both ends of the panel than the conventional one, and the moment generated in the long pin is also small, so that the diameter of the long pin can be reduced. The chain structure of the chain can also be made compact. Further, since the protruding length of the long pin is shortened as described above, the depth dimension of the guide rail corresponding to the protruding length can be made shallow, and the guide rail can be downsized, so that the sleeve dimension of the panel shutter can be reduced. Can be made smaller. Moreover, in the vicinity of the long pin in the chain,
A suspension body corresponding to a conventional guide roller is provided, but since this suspension body projects along the direction orthogonal to the long pin, there is no effect on the projecting length of the long pin or the depth dimension of the guide rail. It does not reach, yet,
When the panel is stored, the panel is suspended on the support rail by shifting to the support rail in the panel storage box.

【Example】

An embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 is a schematic side view of a panel suspension of a panel shutter according to an embodiment of the present invention, FIG. 2 is a partial front view of FIG. 1, and FIG. 3 is a side view of a panel connecting chain. Fig. 4 and Fig. 4 are front views of Fig. 3, and Fig. 5 is a sectional view of a guide rail portion corresponding to Fig. 9, and Figs.
The same or corresponding parts as those in FIG. First, the structure of the chain 4 for connecting the panels will be described. The outer link plates 4a, 4b of the chain 4 (for convenience of explanation, the outer link plate of the panel mounting portion is 4a, and the other outer link plates are 4b). Are integrally formed in a U-shape and a plate shape, respectively, as shown in FIGS. 3 and 5, and the inner link plate 4c is a normal link plate. Then, the outer link plate 4a of the panel mounting portion,
One end thereof is flexibly and rotatably connected to one inner link plate 4c by a normal link pin p, and the other end is rotatably and rotatably connected to the other inner link plate 4c by a long pin P. . In addition, as described above, the inner link plate 4c connected to both ends of the outer link plate 4a of the panel mounting portion, the outer link plate 4b other than the panel mounting portion, and the inner link plate 4c following this is a normal mutual The link pins p are sequentially and alternately connected. In the chain 4 configured as described above, a suspension body 8 that projects near the long pin P in a direction orthogonal to the long pin P is pivotally supported by the outer link plate 4a of the panel mounting portion. This suspension 8 is also for moving to the support rail 7 and suspending the panel 5 on the support rail 7 when the panel is housed in the box 2. The suspension 8 is formed of a slippery material that significantly reduces the sliding contact resistance with the support rail 7, or has the slippery material on the slide contact surface with the support rail 7, or
As shown in the figure, a bearing having rolling bearings, spherical rolling elements, rollers 9 and the like on the support rail 7, and a guide roller 10 as shown in FIG. Any structure may be used as long as it can smoothly move. On the other hand, a support rail 7 that movably supports the suspension 8
As shown in FIG. 2, FIG. 6, and FIG. 7, is composed of a hollow rail member whose central portion on the lower surface is opened along the longitudinal direction, and as shown in FIG. Is integrally formed with a curved rail portion 7a that is curved along the circumference of the sprocket 3. The curved rail portion 7a has a chain pressing function for preventing the chain 4 meshed with the sprocket 3 from coming off and guiding the chain 4 in a predetermined moving direction.
In the above description, the long pin P of the chain 4 only connects the chain 4 and the panel 5, and therefore, as shown in FIG. 5, the long pin P enters the guide rail 1 from the side end of each panel 5. Projecting length of the long pin P projecting
L2 is significantly shorter than the protrusion length L1 of the conventional example shown in FIG. Therefore, the long pin P having the short protruding length L2 also has a small moment, which can reduce the pin diameter. The long pins P shown in FIGS. 5 and 9 are shown to have substantially the same diameter, but in reality, the long pins P shown in FIG.
Is the protruding length L2 of the long pin P shown in FIG.
Since it is shorter than L1, it has a smaller pin diameter than the long pin P of FIG. Therefore, in the chain 4 in this invention, the link structure is also made compact. Further, as described above, the protruding length L2 of the long pin P is the ninth.
By making it shorter than the projection length L1 in the figure, the depth dimension H2 of the guide rail 1 in this invention is also significantly smaller than the depth dimension H1 in FIG. 9, and therefore the guide rail 1 is also made compact. . Next, the operation will be described. However, since most of the operation is the same as that of the conventional example, only the operation of the suspension 8 during the panel storage operation will be described here. At the time of panel storage operation, when the suspension body 8 that rises together with the chain 4 enters the box 2 and reaches the vicinity of the sprocket 3, the suspension body 8 enters the curved rail portion 7a of the support rail 7, It moves in the panel storage direction along the curved rail portion 7a. And the above curved rail part
The suspension body 8 passing through 7a moves the support rail 7 by its own weight along the inclination thereof, and suspends the panel 5 at a predetermined position of the support rail 7 in a suspended state. The plurality of panels 5 that have been moved to (1) are folded and stored in parallel with each other.

[Effect of device]

As described above, according to the present invention, the long pin connecting the panel and the chain in the panel shutter,
When the panel is stored, it moves to the support rail in the panel storage box and separates from the suspension for suspending the panel in a suspended state, and this suspension is provided in the vicinity of the long pin along the direction orthogonal to the long pin. By pivotally supporting the chain so as to project, the long pin only connects the panel and the chain, and since the guide rollers for hanging the panel are not attached as in the conventional case, The protruding length of the long pin can be made significantly shorter than before. Therefore, the moment generated in the long pin is reduced, the diameter of the long pin can be reduced, and the chain link structure can be made compact. In addition, since the projecting length of the long pin is shortened as described above, the depth of the guide rail corresponding to this projecting length can be made shallow, and the size of the guide rail can be miniaturized. Can be made smaller. Moreover, since the suspension body projects in the direction orthogonal to the long pin, it has no effect on the projecting length of the long pin or the depth dimension of the guide rail, and yet supports the inside of the panel storage box when storing the panel. There is an effect of shifting to the rail and suspending the panel in a predetermined suspended storage state on the support rail.
