Description

Description: TECHNICAL FIELD The present invention relates to a panel suspension structure for a panel shutter,
Specifically, in a panel shutter in which a panel constituting a shutter curtain is hung by a hanging roller chain and the opening is opened and closed by hanging, the panel is formed into a curved panel along the longitudinal direction, and The present invention relates to a panel suspension structure of a panel shutter that can be lifted and suspended while maintaining an equilibrium posture when a panel is opened and closed.

[Prior Art] In a conventional panel shutter, a plurality of flat panel-shaped panels are suspended by a roller chain pivotally connected to roller support shafts having upper and lower edges on both left and right sides thereof, and are attached to both ends in a storage case. The opening portion is configured to be opened and closed by interlocking with up and down movement along the guide rail in the vertical direction and lateral movement along the storage rail in conjunction with forward and reverse rotations of the provided guide sprocket.

However, in the case where the panel is formed in a flat plate shape, a facility that requires special pressure control to ensure airtightness, such as an air dome where the internal pressure is higher than the external pressure, or a nuclear facility where the internal pressure is lower than the external pressure, or radioactive When it is installed in an opening of a facility that handles substances, there is a drawback that the panel bends due to the difference in internal and external pressures and air tightness cannot be ensured.

On the other hand, recently, with the diversification of buildings, the appearance of buildings has been designed, and in particular, the number of buildings with curved outer walls is increasing. It is required to install a panel shutter that matches the curved surface of the outer wall.

[Problems to be Solved by the Invention] The present invention has been conceived in view of the above-mentioned circumstances, in order to eliminate conventional drawbacks and meet the demands of users.
The purpose is to form the shutter curtain panel into a curved panel along the longitudinal direction, and at the time of opening and closing, the panel is lifted and hung while maintaining its equilibrium posture. Although it is a curved panel, it can be installed on either convex panel shutters or concave panel shutters depending on the environment of the shutter installation location. Therefore, special pressure control is required due to the large pressure difference between the inside and outside. It can be installed as a concave panel shutter for facilities such as an air dome to ensure sufficient airtightness, and as a convex panel shutter for nuclear facilities and facilities handling radioactive materials. It is not possible to ensure sufficient air-tightness, and against the curved outer wall of buildings, which has recently been increasing. Can be installed in harmony with the curved surface of the outer wall, and in combination with improving the freedom of design in pursuit of the exterior of the building, it can satisfy the potential needs of consumers. There is an attempt to provide a panel suspension structure for a panel shutter.

[Means for Solving the Problems] In order to solve the above problems, the technical means adopted by the present invention is to form a panel into a curved panel along the longitudinal direction, and from the upper and left edges of both left and right sides of the panel. It is characterized in that a mounting metal fitting is extended toward the convex side, and a roller support shaft pivotally connected to the hanging roller chain via the mounting metal fitting is provided at a position balanced with the center of gravity of the curved panel. is there.

Further, when a roller support shaft in which a hanging roller chain is pivotally connected is provided at the upper and left edges of both right and left sides of the curved panel, a flat plate-like balance weight that balances the center of gravity of the panel is provided at the lower edge of the concave side of the panel. Or a mounting metal fitting is provided at the lower end edge of the central portion in the longitudinal direction on either the convex surface side or the concave surface side of the panel, and the suspending sub roller chain is pivotally connected via the mounting metal fitting. It is a feature.

[Operation] Therefore, according to the present invention, even if the panel forming the shutter curtain is formed as a curved panel, the lifting roller chain lifts the panel while maintaining the equilibrium posture without biasing the center of gravity of the panel, The opening can be opened and closed by being hung. Therefore, depending on the environment in which the shutter is installed, the convex panel shutter or the concave panel shutter can be easily installed.

In the third embodiment, the hanging sub roller chain 14 is provided on the convex side of the curved panel and the panel shutter is set as a concave panel shutter. If is provided on the concave side,
It goes without saying that it can be installed as a convex panel shutter.

In the third embodiment configured as described above, the curved panel 2 is constituted by the hanging roller chain 4 that meshes with the guide sprocket 10 and the auxiliary sub roller chain 14 that meshes with the guide sprocket 15. Since the panel is a curved panel, the guide rail is interlocked with the synchronous forward and reverse rotations of the guide sprocket 10 and the guide sprocket 15 because the panel is a curved panel. The up-and-down movement along 7 and the lateral movement along the storage rail are smoothly interconnected to open and close the opening.

[Effects of the Invention] In short, according to the present invention, the panel forming the shutter curtain is formed as a curved panel along the longitudinal direction, and the panel is hung and hung while maintaining the equilibrium posture when opening and closing the opening. With this configuration, the following remarkable effects can be obtained as compared with the conventional panel shutter in which the panel is formed in a flat plate shape.

(1) By forming a single curved panel, the convex panel shutter or the concave panel shutter can be easily installed depending on the environment of the installation location of the shutter.

(2) Therefore, by installing a concave panel shutter in a facility that requires special pressure control to ensure airtightness, for example, at the opening of an air dome where the internal pressure is higher than the external pressure, the indoor airtightness can be improved. Adequate pressure control is possible by ensuring sufficient pressure.In addition, a concave panel shutter is installed at the opening of the nuclear facility where the internal pressure is lower than the external pressure or the facility that handles radioactive materials, ensuring sufficient air tightness indoors. It is possible to prevent leakage of contaminated air.

(3) In addition, for curved outer walls of buildings, which have recently been on the increase, a panel shutter that matches the curved beauty of the outer walls can be installed in the opening, and a design that pursues the appearance of the building is pursued. The degree of freedom of can be significantly improved to meet the potential needs of consumers.
