SOLUTION: In the case of housing a rolling door in a housing box 3, a motor is driven to cause the travel of a chain, thereby moving the rolling door in an X- direction. Then, when a rotor 11 comes in contact with an operational fitting 18 on a guide rail 17b and rotates in a Y-direction, the end 11a of the rotor 11, while sliding on the reverse side of a projection piece 16 in a Z-direction, lifts a rolling door constituting member 1C in the X-direction. Also, when the rolling door is further moved in the X-direction, the rotor 11 is made to rotate via the operational fitting 18, and the end 11a thereof slides on the reverse side of the projection piece 16 in the Z- direction. The end 11a continues to slide until positioned in parallel with a rolling door travel direction. In addition, when the rolling door is made to further travel in the X-direction, the constituting member 1C is moved laterally via the rotor 11, and stored in the housing box 3 in an upright state. Thereafter, a constituting member 1b and so forth are stored in sequence.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for connecting and releasing a plurality of shutter components forming a shutter installed in various buildings.

[0002]

2. Description of the Related Art Shutters are widely used in various buildings such as houses and large buildings. This shutter has a shape that is long in the width direction, and a plurality of shutter components connected to each other in the movement direction are used by being pulled out from a storage box and stored in the storage box when not in use. In addition, when the shutter moves, the shutter components are always connected and fixed, so that when stored, the shutter components alone are wound around the shaft while being slightly curved and deformed.

[0003]

Therefore, in the conventional shutter, a single shutter component is formed so as to be easily deformed in order to smoothly take up and store it on a shaft and rewind the shaft. For this reason, the thickness of the shutter constituent member alone is reduced, and the portion where the shutter constituent members are connected to each other is easily bent in consideration of deformation. Therefore, when the shutter is used, when it receives a pressing force from the outside, the whole is easily deformed in a wavy manner, and there is a problem that there is no toughness. In order to solve this problem, a method of providing a reinforcing member inside the shutter has been proposed. However, according to this method, a new disadvantage occurs in that the shutter configuration is complicated and the storage is complicated.

[0004] To solve this problem, another method has been proposed in which the shutter constituent member is made to have a strong structure and can be connected and released freely. However, this conventional example has a problem that the shutter components are not smoothly connected to each other in a concavo-convex configuration, and a gap is often formed between the shutter members after the shutter is lowered, so that a sufficient shutter function cannot be performed. was there. Further, since the shutter components are connected via a chain, loose chains are accumulated in the storage box in a complicated manner, and the smoothness when the shutter components are pulled out from the storage box is impaired. There was also.

SUMMARY OF THE INVENTION The present invention is proposed to solve the above-mentioned problems, and is intended to smoothly connect and release independent and tough individual shutter components, and to connect and release shutter components. It is intended to provide a structure.

[0006]

According to the present invention, in order to achieve the above object, a plurality of shutter components are connected to each other, and when not in use, the shutter members are moved via guide rails and stored in a storage box. In the connection and release structure of the shutter component members of the shutter that is fed out of the storage box at the time of use,
At one end in the moving direction, an engaging portion having a mountain shape is formed at the side in a side view, and at the other end, an engaging receiving portion of a V-groove is formed at the other end. A rotating member receiving portion for sliding the tip of a rotating member provided on a shutter component adjacent to the engagement receiving portion is provided, and an operation tool for operating the rotating member of the rotating member is provided on the guide rail; When the shutter is housed, the shutter members are released from the connected state inside the housing box by the operation of the rotating body, and when the shutter is extended, the shutter members are interconnected by the operation of the rotating body. Further, a non-combustible member is provided on the back surface of the shutter component alone. Further, a sliding assist member is provided on the sliding surface of the rotating body or the rotating body receiving portion. The sliding assist member is a ball bearing.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic perspective view of a shutter device according to the present invention. The shutter component 1 is
It is long in the width direction and made of a hard material such as steel. The plurality of shutter components 1 are mutually connected in the moving direction (the direction of the arrow) to form the shutter 2. The shutter 2 is pulled out of a storage box 3 provided at an upper portion and descends as shown in the drawing, and is stored in the storage box 3 when not in use. In this case, shutter 2
The movement in the direction of the arrow is performed by moving the chain 5 by driving the motor 4 provided in the storage box 3.

That is, the shutter 2 has one end fixed to the shutter component 1a at the front end and moves along with the movement of the chain 5, the other end of which is fixed to the chain winding shaft 6 provided in the storage box 3. It is designed to move. In addition,
Reference numeral 7 denotes a rotating tool for moving the shutter component 1 in the storage box 3.

FIG. 2A is an enlarged perspective view showing the shape of the shutter constituting member 1. In the drawing, two shutter constituting members 1 are shown.
This shows a state where b and 1c are connected. As shown in the drawing, the first shutter component 1b has an engaging portion 8 formed in a side view in the movement direction (A (-) direction) of the shutter 2 and a V-shaped groove in the other end. A receiving portion 9 is formed. In addition, a rotating body 11 that rotates along the side surface 10 is provided near the engaging portion 8. This rotating body 11
Can be rotated in the direction of arrow B via the fulcrum 12. Further, near the engagement receiving portion 9 on the side surface 10 of the shutter component member, there is provided a rotating member receiving portion 16a that slides in contact with the tip of a rotating member (not shown) of the succeeding shutter component member. Note that the second shutter component 1c is different from the first shutter component 1b in that a rotating body is not provided.

Next, the second shutter component 1c has an engagement portion 13 formed in a mountain shape in a side view at an end portion in the moving direction (A (-) direction) of the shutter 2, and a V-shaped groove at the other end. An engagement receiving portion 14 is formed. Further, a rotating body receiving portion 16b is provided in the vicinity of the engagement receiving portion 14 on the side surface 15 of the shutter component member to make the tip of the rotating body 11 contact and slide. FIG. 2B is an enlarged perspective view showing the relationship between the rotator receiving portion 16 and the rotator 11, but as shown, the rotator receiving portion 16 is fixed to the shutter component side surface 15 via a fixing piece 16a. The projection 16b is projected in a right angle direction.

On the other hand, the rotating body 11 rotates under the control of the operating tool 18, and its tip 11a comes into contact with and slides on the back surface of the protruding piece 16b, thereby connecting and releasing the shutter constituting members as described later. It has become. Therefore,
The tip 11a of the rotating body 11 contacts the back surface of the projection 16b,
What is necessary is just to attach a sliding assistance member so that it may slide easily. In the drawing, the tip 1 of the rotating body 11 is used as a sliding assist member.
A specific example in which a ball bearing 11b is attached to 1a is shown.

FIGS. 3 and 4 show the operation in which the shutter components 1 of the shutter 2 constructed as described above are connected to and separated from each other, and are drawn out of the storage box 3 or stored. FIG. The drawing shows a case where each shutter component 1 moves and is stored in the storage box 3. In this case, the motor 4 provided in the storage box 3 is driven to move the chain 5, and each shutter component 1 is moved in the X direction.

Now, it is assumed that the second shutter component 1c is located at the forefront in the X direction, and that the first shutter component 1b is located subsequently. Both move in the connected state between the guide rails 17a and 17b to the vicinity of the storage box 3, and when a part of the second shutter component 1c enters the storage box 3 (FIG. 3A), Further X
When it moves in the direction, the rotating body 11 hits the operating tool 18 provided on the guide rail 17b and is rotated in the Y direction (FIG. 3B). Then, the tip portion 1 provided with the bearing 11b of the rotating body 11 which is in contact with the back surface of the protruding piece 16b.
1a lifts the second shutter component 1c in the X direction while sliding on the back surface of the projection 16b in the Z direction. 19
Shows the gap between the two shutter components resulting from this lifting.

When the shutter 2 is further moved in the X direction, the rotating body 11 is rotated by the operating tool 18, and its tip 11a slides on the back surface of the projection 16b in the Z direction, as shown in FIG. 3C. It slides until it is positioned parallel to the shutter movement direction. In this case, the end of the second shutter component 1c in the moving direction has moved to a position where the end is in contact with the ceiling 3a of the storage box 3 and is suppressed. In this state, when the shutter is further moved in the X direction, the first shutter component 1b moves upward as it is,
The second shutter component 1c cannot move upward, but is moved laterally (rightward in the drawing) by the rotating body 11 as shown in FIG. 4A. Then, the posture is reestablished so as to stand upright as shown in FIG. 4B.

This series of operations is repeated for the first shutter component 1b and further succeeding shutter components (the same configuration as the first shutter component 1b). Then, the shutter components are successively stored in the storage box 3 in an upright state as shown in FIG. 4B. Meanwhile, in order for the shutter components to be stored in the storage box 3 in an upright state as shown in FIG. 4B, it is necessary that the shutter components be moved smoothly in the W direction. .

Therefore, as shown in FIG. 1, rotating members 7 are provided at both ends in the width direction of the shutter constituting member in the storage box 3, and the rotating members 7 are configured to rotate in the depth direction of the storage box 3. The shutter member is placed on the rotating body 7 and is rotated in the W direction (FIG. 4b) when the shutter is stored. I try to rotate it.

The operation of unwinding the shutter components from the storage box 3 will be described. Since all the shutter components are stored in the storage box 3 in a separated state, the motor 4 is moved in the direction opposite to the direction when the motor is stored. The chain 5 is driven to move. At the same time, when the rotating body 7 is rotated in the direction opposite to the direction of W, the rotating body 7 is unreeled from the shutter component housed last. Then, by the operation opposite to the operation shown in FIGS. 3 and 4 described above, the shutter components are moved from the storage box 3 in the opposite direction to X while being connected to each other. In this case, since the connecting portions between the shutter components are formed such that one engaging portion has a mountain shape and the other receiving portion is a V-groove, the engaging portions are connected so as to be guided to the inclined surface of the V-groove. However, the connection can be made very smoothly. In addition, after the connection, the connection state can be maintained without any gap due to the weight of the shutter constituting member.

Thus, when the shutter 2 is lowered,
Although the shutter components are connected to each other without gaps, they are not always sufficient for fire prevention measures. That is, even if the shutter 2 is formed using steel or the like as a material, the shutter 2 may be melted when exposed to a heat higher than expected. Therefore,
By providing a non-combustible member such as ceramic on the back surface of the shutter constituent member, a fire prevention effect can be expected.

[0019]

As described above, according to the present invention, the separate and independent strong shutter components can be smoothly connected and released, so that the shutter can be stored and extended. Can be performed smoothly. In addition, after the connection, no gap is formed between the shutter components, and the strong connection state can be maintained, so that there is almost no deformation due to the pressing force from the front and back directions of the shutter. Further, by providing a non-combustible member such as a ceramic on the back surface of the shutter component, a fire prevention effect can be expected.
