Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a building panel in which an opening is opened and closed by moving a ceiling part in a substantially horizontal direction, and is stored in a vertical storage rail. The present invention relates to a guide rail allocating structure in a shutter.

[Problems to be Solved by Prior Art and Invention] In general, in a panel shutter for a building, a panel body moves a ceiling portion in a substantially horizontal direction to open and close an opening, and is stored in a vertical storage rail. Some have been configured to do so. However, in this structure, when the panels are to be stored in a stacked state, it is necessary to guide the rollers provided at the front and rear in the moving direction of the panel body to different storage rails. Therefore, conventionally, the guide rails at the openings following the storage rails also had a double rail structure so that the front and rear rollers individually roll, but in this case, a double rail material is required and the entire rail is It is not allowed to be heavy, and there are drawbacks such that two types of curved rails must be prepared because the inner and outer rails have different curvatures at the rail corners.

Therefore, it is also proposed to make the guide rail on the opening side into a single shape, but in such a case, it is necessary to separate the front and rear rollers at the boundary portion between the guide rail and the storage rail. In order to reliably and smoothly carry out the above, a complicated distribution mechanism is inevitably required, but there is a problem that the conventional distribution mechanism is inevitably complicated.

[Means for Solving the Problems] The present invention was conceived in view of the above circumstances and was devised with the object of providing a guide rail allocating structure in a building panel shutter that can eliminate these drawbacks. , Rollers with the same rolling locus are provided on one side of the front and rear ends of the left and right edges of the panel that constitutes the shutter curtain, and the guide rail structure that these rollers travel is used. A single guide rail with a single rolling surface is formed. As the first and second storage rails, when the panel bodies that are fed out flush with the guide rails are stacked and stored in the first and second storage rails, the left and right edges of the panel body are stored. On the other side of the front and rear ends, the first and second guide rods project from the panel surface in different amounts of protrusion, passing through different trajectories, while the guide rail extends from the storage rail. At the roller distribution position, the first guide rod, which is located in the middle of the different movement loci of both guide rods and has a large protrusion, passes through the outer side opposite to the side where the second storage rail is located and passes through the first of the panel body. (2) The roller is guided to the corresponding first storage rail while restricting movement toward the storage rail side, and the second guide rod on the side projecting small passes through the side on which the second storage rail is provided and moves the roller to the corresponding second storage rail. It is characterized in that a sorting bracket for guiding to the storage rail is provided.

Further, according to the present invention, according to this configuration, although the storage rails are two and the guide rails are one, the rollers at the boundary portions of both rails can be distributed smoothly with a simple structure. It was made possible.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a panel-type shutter curtain, and the shutter curtain 1 is formed by connecting chains 2 of a plurality of panel bodies 10 at intervals with a chain. Reference numeral 3 is a single type guide rail horizontally installed along the opening (ceiling), and is provided with an R-shaped rail portion 3a bent downward at the corner of the opening. The first and second storage rails of the inner-outer double type are formed so as to form a storage portion of the shutter curtain 1 which is separated in a divergent manner.

On the other hand, front and rear rollers 12 and 13 running on the guide rail 3 (the closed side of the shutter curtain 1 is referred to as “front”) are provided on the lower surfaces of the front and rear ends on both sides of the panel body 10 via roller support bodies 11. On the other hand, panel guides 12a and 13a having small and large rising dimensions are provided on the upper surfaces of the front and rear ends of the panel body 10 via the support body 14 from the panel surface to the outside, respectively. Further, second and first guide rods 12b and 13b are formed at the tip ends of the panel guides 12a and 13a by bending the same dimension toward the outer side of the panel. The second and first guide rods 12b and 13b respectively follow different movement loci Y and X when the panel body 10 is opened and closed. Also, for example, the front roller of the panel body 10
Between the 12 roller shafts, the chain 2 is suspended by pivotally supporting the roller 2 by means such as inserting the link of the chain 2 described above, whereby the panel body 10 is connected. . Reference numeral 6 is an opening / closing device, and 7 is a sprocket for driving the chain 2 by forward / reverse driving by the opening / closing device 6.

On the other hand, 20 is a connecting portion 23 to which the R-shaped rail portion 3a of the opening-side guide rail 3 is connected at the upper portion, and second and first storage rails 4 and 5 branched in a bifurcated shape at the lower portion. A distribution bracket in which the connection parts 21 and 22 are connected to each other, and the distribution bracket 20 includes second and first guide rods.
The distribution body 25 is located between the movement loci Y and X of 12b and 13b.
Is formed, and the distribution body 25 is formed by the R-shaped rail portion 3a.
By guiding each of the second and first guide rods 12b and 13b of the panel body 10 that has been guided and lowered, the front and rear rollers 12 and 13 are distributed to the second and first storage rails 4 and 5, respectively. It is configured.

That is, when the panel body 10 descends toward the storage rails 4 and 5, the first guide rod 13b that moves in advance while passing the locus X is located on the outer guide surface 25b located outside the sorting body 25. It is guided and passes through the side opposite to the side where the second storage rail 4 is located (the direction of the arrow X ₁ ), whereby the roller 13 is on the side of the first storage rail 5 that is almost directly below the guide rail 3 (the direction of the arrow). It is designed to be guided in the X ₂ direction (see FIGS. 6 and 7). Then, next, the second guide rod 12b, which moves backward along the locus Y, is guided by the guide surface 25a located inside the sorting body 25 and passes through the side where the second storage rail 4 is located. As a result, the second guide rod 12b becomes the second lateral storage rail 4
Side (arrow Y ₁ direction) is forcibly guided (Fig. 8,
(FIG. 9), whereby the front roller 12 of the panel body 10 is guided in the direction of the arrow Y ₂ on the second storage rail 4 side on the inner side, and thus the second roller on the inner and outer sides of the rollers 12, 13, It is possible to guide the distribution to the first storage rails 4 and 5.

In the embodiment of the present invention configured as described above, when the shutter curtain 1 which is now expanded to be flush with the opening and closed is housed, the chain 2 is rewound by driving the opening / closing device 6. Then, the panel body 10 on the side closest to the switchgear 6 is stored in the inner and outer storage rails 4, 5, but in this case,
When the panel body 10 descends the R-shaped rail portion 3a and approaches the rail distribution bracket 20, as shown in FIGS. 6 and 7, the first guide rod 13b, which largely protrudes, moves the distribution body 25.
As it passes through the outer guide surface 25b, the movement of the inner side toward the second storage rail 4 is restricted, and it descends in the direction of the arrow X ₁ along the vertical guide portion outer guide surface 25b, Therefore, the roller 13 also rolls down in the vertical direction (X ₂ direction) and is guided to roll through the connecting portion 22 to the outer first storage rail 5.

Then, when it further descends, the second guide rod 12b protruding slightly from the panel body 10 is, as shown in FIGS. 8 and 9,
The roller 12 is distributed to the inside of the distribution body 25, abuts on the inclined guide surface 25a, and descends in a state of being distributed in the direction of the arrow Y ₁ along this, and accordingly, the roller 12 moves from the connection portion 23 to the connection portion 21. Is regulated and guided to the direction of the arrow Y ₂ , that is, the inside of the second storage rail 4 descends. In this case, since the distance between the second and first guide rails 4 and 5 is formed so as to spread downward, the rollers 12 and 13
The panel body 10 rolls faster, and the panel body 10 is stored while gradually approaching the horizontal posture as it descends. In this way, the front and rear rollers 12, 13 of the panel body 10 to be continued in the same manner are similarly distributed to the inner and outer second and first storage rails 4, 5 and are stored in a superposed manner as shown in FIG. .

Further, when the shutter curtain 1 is closed, it is pulled up by the chain 2 from the front roller 12 side. Therefore, contrary to the above, the rollers 12 and 13 are separate inner and outer double type second and first storage rails 4 and 5. From above to the same guide rail 3 through the single type R-shaped rail portion 3a above the distribution body 25, the panel body 10 is quickly pulled up on the front roller 12 side at the rail distribution bracket 20 site, and From the roller 12 side, it rises and is guided to the R-shaped rail portion 3a, and is sequentially fed to the single guide rail 3 side to close the opening.

As described above, in the embodiment of the present invention, the number of horizontal guide rails on the opening side is one, the number of storage rails in the vertical direction is two, and the panel body 10 closes the opening in a flush state. While it is configured such that the front and rear of the panel body 10 can be stored in a stacked state with the front and back of the panel body 10 aligned on the same side, the front and rear rollers 12 and 13 provided on the panel body 10 are used to store the second and first rollers. Therefore, the guide can be reliably distributed to the storage rails 4 and 5. Moreover, this sorting guide is different from the movement trajectory X by the second and first guide rods 12b and 13b,
The middle of Y is distributed by the rail distribution body 25 so as to be branched into the inside and outside, and the rear roller 13 that descends in advance is guided as it is to the first storage rail 5 side that is directly below, and the front roller 12 that descends in the rearward direction is inclined. The inclined guide surface 25a guides the second storage rail 4 on the inner side, so that the rollers 12 and 13 can be reliably and smoothly distributed.

[Advantageous effects] In short, since the present invention is configured as described above, the storage rails that are stacked and stored in a vertically laminated form are the first and second double type, but the horizontal opening side. The guide rail is a single type so that the guide rail structure can be lightened and simplified, but when the panel body is stored, the front and rear rollers are distributed to the first and second storage rails. However, the first guide rod of the first and second guide rods that protrudes on the side opposite to the front and rear rollers of the panel body has the largest protrusion, and the first guide rod on the opposite side of the sorting bracket from the side on which the second storage rail is located. It guides the roller to the corresponding first storage rail side while restricting the movement of the panel body toward the second storage rail side through the second guide rod with a small protrusion amount, and has the second storage rail of the sorting bracket. The roller is guided to the corresponding second storage rail while forcing the movement of the panel body to the side of the second storage rail passing through the side, and thereby the single guide rail on the horizontal opening side is provided. Therefore, the storage rails oriented in the vertical direction can surely perform the alternating distribution of the rollers to the double storage rails without making a mistake.

Moreover, since this distribution bracket has a structure which is located in the middle of the first and second guide rods which move in different movement loci and is distributed to the first and second storage rails, the distribution mechanism is simple and smooth and reliable. The front and rear rollers can be distributed to the corresponding storage rails.
