[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laterally opening shutter formed by vertically extending a unit panel that is slender in the vertical direction, and more particularly to a shutter that is pulled out along a rail having a corner. Alternatively, the present invention relates to a side-opening shutter characterized by the connection structure between unit panels in a pull-out side-opening shutter that is pushed in to open and close.

[0002]

2. Description of the Related Art Shutters are classified into a vertical opening type and a horizontal opening type according to the opening / closing direction, and are classified into a folding type, a drawing type and a winding type according to the opening / closing structure. It The vertical opening type means moving the shutter up and down to open and close, and the lateral opening type moving left and right to open and close. The foldable type is a unit that opens the shutter by zigzag folding the unit panels that form the shutter surface. The take-up type is to wind the unit panel and open the shutter.

Conventionally commonly used shutters are
It is a drawer-type or roll-up type vertical opening shutter and a folding horizontal opening shutter. The former is installed mainly at the openings of buildings such as the entrances of shops and garages that face the outside of the building, and the latter is often used as a partition wall that can be opened and closed.

[0004]

SUMMARY OF THE INVENTION The present invention has been made for the purpose of obtaining a shutter having a more rational structure to be used in places where strength and durability are required, such as garage doors and elevator doors. Is. The conventional vertical opening shutter used in this kind of place is sturdy and therefore requires power to open and close the heavy shutter, and even if it is opened and closed by the prime mover, it takes time to open and close, especially when it is in a half-opened state. There is a lot of fear when passing. In addition, since the unit panel is horizontally long, dust is easily attached to the connecting part, and the weight of the shutter acts on the connecting part of the panel, so the connecting part has a rugged structure and a large force is applied to the connecting part when opening and closing the shutter. Since the light is refracted when applied, there is a lot of noise when opening and closing. Furthermore, because it takes force to open the shutter, children who are weak can not open it, and when it is electrically operated, it can not be opened when the power is turned off, and it takes time to open it. Therefore,
It becomes an obstacle to evacuation in an emergency.

On the other hand, in the case of a folding type or a winding type that opens sideways, when the shutter is made to have strength, the unit panel becomes thick, and the occupied space in the folded state or the rolled state becomes large, resulting in an opening area. Becomes narrower. Especially, the roll-up type does not fit well in the wound state,
Different operations are required for winding and pulling. On the other hand, in the foldable type, since it is necessary to bend the connecting portions of the panels to each other by 180 degrees at the time of folding, if the panel is made thick to have strength and the connecting portion also has sufficient strength, The structure of the connecting portion becomes complicated, the number of parts increases, and the cost becomes very high.

In view of the above problems of the conventional device, the present invention is light and quiet to open and close, has a large opening area, has a simple structure, and has sufficient strength and durability for outdoor use. The object was to provide a drawer-type side-opening shutter with a unique appearance. Especially in garages, etc., the floor surface of the part where the shutter is drawn in is often inclined for drainage. In view of this, it is an object to obtain a laterally-opening type shutter that can travel along an inclined rail.
Further, according to the present invention, when a part of the unit panel constituting the shutter is damaged, the damaged panel can be easily replaced and the shutter can be installed without using a crane or the like. The challenge is to obtain.

1 is provided, and a safety panel 42 is mounted between the fitting groove 41 and the floor surface except for the entrance / exit portion. Since the safety panel covers the shutter 30 that moves along the side wall surface, it is possible to eliminate the fear of moving the shutter. Therefore, the safety panel 42 is necessary when the shutter 30 is provided in an object such as an elevator that accommodates a person inside.

A single unit panel 1 has its longitudinal sides 2, 3 guided by a side wheel 18 mounted on the panel and a side wheel of the unit panel adjacent to one longitudinal side 2 of the convex cross section. ing. Therefore, as shown in FIG. 2, in the portion where the rail 31 curves in the horizontal plane, the center of the upper side of the unit panel 1 (suspended wheels 11, 12) follows the locus as shown by the imaginary line in FIG. Move to. Suspended wheel 1
The opening 13 provided in the bracket 9 on the outer side of the panel that supports 1 and 12 is provided to prevent the rail 31 and the bracket 9 from interfering with each other at this time. The cross-sectional shape of the rail in FIG. 4 shows the shape of a straight line portion, and in the curved portion, the vertical rib 32 cannot be provided at the position shown in FIG.

The side-opening shutter 30 is assembled at the end of the rail. At the time of assembly, the unit panels connected by the following procedure are sequentially fitted into the rail,
A side opening shutter of desired length is assembled. Adjacent unit panels 1 have one vertical side 2 as shown in FIG.
The insertion holes 21 and 22 are connected to each other in a state in which they are inserted into the support shaft 15 and the short pin 17 of the other vertical side 3 of the adjacent unit panels. This connection is performed by inserting the insertion hole 21 deep into the support shaft 15 and then inserting the short pin 17 into the hole 22. In this connected state,
A vertical play 27 is formed between the upper bracket 14 and the upper end of one side 2 of the adjacent unit panel. That is, the panels adjacent to each other by this play space can move relative to each other in the vertical direction and can be moved integrally. The unit panels 1 can be removed one by one by removing the fitting between the short pins 17 and the holes 22, and then removing the support shaft 15 from the insertion hole 21.

Since the adjacent panels can move up and down relative to each other, the shutter 30 can be moved without colliding with the floor even when the retracted portion of the rail 31 has a vertical inclination as shown in FIG. You can At this time, the adjacent unit panels are slightly stepped up and down to form a staircase. For example, when the laterally-opening shutter 30 is installed in a garage of an automobile or the like, as shown in FIG. 2, the traveling direction is changed by 90 degrees at both ends of the doorway 36, and the doorway 36 is drawn along the wall surfaces on both sides of the doorway 36. . The floor surface of the garage is often inclined in the front-back direction for drainage or the like. In such a case, if the retracted portion of the rail is left horizontal, the lower side of the shutter will collide with the floor surface. With the shutter of this invention, the structure described above allows the rail to travel even when the rail is tilted vertically. Therefore, by tilting the rail parallel to the floor surface, a gap is created between the shutter and the floor surface. Occur,
It is possible to avoid the lower side of the shutter from colliding with the floor.

A synthetic resin shoe 37 (see FIG. 3) having a downwardly facing U-shaped groove is fixed to the lower end side of the unit panel 1, and a guide piece 38 provided on the floor of the garage is used. Be guided. The guide pieces 38 can be guided at a predetermined interval in the moving direction of the shutter, the direction of the unit panel 1 is defined by the side wheels 18 on the upper side, and the shift between adjacent panels is prevented. Since the structure is such that even if the guide pieces 38 are provided with a certain distance therebetween, the guide action is not hindered.
