Description

The present invention relates to a panel shutter device, and more particularly to a panel shutter device installed in an opening having a large ceiling space.

The panel shutter device connects a plurality of panels with support shafts with guide rollers at both ends in the longitudinal direction, and connects them up and down with a chain via the support shaft. The panel is sequentially guided to the storage rail in the storage unit provided in the storage unit, the panel is stored in the storage unit, and the opening is opened. When the opening is fully closed, the plurality of panels close each other in the vertical direction to close the opening, so that the panel shutter device has a good soundproofing performance. Therefore, the panel shutter device is advantageously employed for openings that require soundproofing performance and airtightness.

When the panel shutter device is fully opened, the panel is stored in a storage unit provided above the opening. Depending on the installation location of the panel shutter, a high position in the space above the ceiling above the opening (the height of the ceiling is high). In some cases, it is necessary to provide a storage portion at the position). In that case, if a panel is provided up to the storage unit installed at a high position on the ceiling, the number of panels increases, the weight of the entire panel shutter increases, and the opening / closing function force is exceeded. Therefore, how to reduce the weight of the entire panel shutter is important. On the other hand, when only the number of panels that can close the opening is suspended with a chain, the weight of the entire panel shutter is almost the same as that of a normal panel shutter, but the upper chain of the uppermost panel is guided by the chain. Since it swings in the rail (since there is no guide roller moving in the guide rail), it is difficult to move the panel up and down stably.

Here, Patent Document 1 discloses a panel shutter device in which a smoke exhausting part is formed in an upper part of an opening when the opening is fully closed. In this thing, although the smoke exhaustion part is formed with the pipe, the pipe of patent document 1 is for the purpose of smoke exhaustion, and there is no technical idea of reducing the weight of a panel, and smoke exhaustion. The section corresponds to an area of at most one panel.
Reality 7-48957

An object of the present invention is to reduce the total weight of the panel shutter applied to the driving means for opening and closing the opening in the panel shutter device.

The panel shutter device adopted by the present invention in order to achieve such a problem is a lower half portion erected at both ends in the width direction of the opening portion and an upper half portion extending vertically in the internal space above the opening portion. A pair of guide rails, a pair of storage rails located above the upper half of the guide rail and extending in the lateral direction, and a plurality of panels having guide rollers at both longitudinal ends. A plurality of longitudinal members that are lighter than the panel, and the plurality of panels are positioned on the lower side and the plurality of longitudinal members are positioned on the upper side. A connecting member to be connected, and a driving means for moving the panel and the longitudinal member connected by the connecting member along the guide rail and / or the storage rail via the guide roller. The height at which the plurality of panels are continuously provided corresponds to the height of the opening, and the plurality of longitudinal members are always stored in the internal space above the opening. When the opening is fully closed, both longitudinal ends of the panel are accommodated in the lower half of the guide rail, and both longitudinal ends of the longitudinal member are accommodated in the upper half of the guide rail. The opening is closed only with the panel while being concealed in the upper internal space. When the opening is fully opened, both longitudinal ends of at least some of the plurality of longitudinal members are accommodated in the accommodation rail.

In one aspect, the pair of storage rails extending in the lateral direction are rails that gently extend downward from the front to the rear as in the embodiments described later, and are a normal panel shutter device. The storage rail used for the can be used. As another embodiment of the storage rail, it may extend horizontally from the upper end of the guide rail while being bent in a curved manner, like a guide rail of a so-called overhead door. Further, the guide rail and the storage rail may be integrally formed.

The longitudinal member that is lighter than the panel is a pipe in one embodiment, but is a member having an opening in the surface of the panel (for example, a member consisting only of the frame of the panel and the supporting shafts at both ends in the longitudinal direction, or the panel surface. Or a punching metal having a large number of holes). Moreover, a chain and a wire are illustrated as a connection member which connects a panel and a longitudinal member. In the case where the connecting member is constituted by a chain, in one aspect, the support shafts (the guide rollers are supported by shafts) projecting from both ends of the panel and the longitudinal member in the longitudinal direction are connected vertically by the chain.

In one aspect, the panel shutter device divides a space having a high ceiling surface and a low ceiling surface into a high “ceiling height” space and a low “ceiling height” space. The lower half of the guide rail is located in a low “ceiling height” space, and the upper half of the guide rail is an opening surrounded by a wall surface connecting the high ceiling surface and the low ceiling surface and the low ceiling surface. In the internal space above the section, it extends in the vertical direction, and the storage rail is located above the high ceiling surface. In a preferred aspect, a space partition system is configured from the first panel shutter device configured by the panel shutter device according to claim 3 and the second panel shutter device provided on the low ceiling surface side of the first panel shutter device. To do. The second panel shutter device has an opening fully closed posture in which a plurality of panels connected via a connecting member are guided by a pair of guide rails erected at both ends in the width direction of the opening to close the opening. The panel has an opening fully open position that is guided and stored by a pair of storage rails in the storage section above the low ceiling surface. When the opening is fully closed, the panel of the first panel shutter device and the second panel shutter A space is formed between the device panel and a space having a high ceiling surface and a low ceiling surface is divided into a high “ceiling height” space and a low “ceiling height” space. The space partitioning system is preferably provided as a soundproofing (soundproofing) system by providing a soundproofing material inside the panel or the ceiling. Further, if a heat insulating material is provided instead of or in addition to the soundproofing material, a heat insulating effect can be obtained.

According to the present invention, since the longitudinal member that is lighter than the panel is disposed on the upper side of the panel for closing the opening, the total weight applied to the shutter driving means can be suppressed. Since the longitudinal member that is lighter than the panel is always stored in the internal space above the opening (the space in the ceiling), it is not exposed to the outside.

Since both ends in the longitudinal direction of the longitudinal member that is lighter than the panel are provided with guide rollers in the same way as both ends in the longitudinal direction of the panel, both ends in the longitudinal direction of the longitudinal member are stably guided in the guide rail and the storage rail Is done. Moreover, the panel shutter apparatus of this invention can be comprised using the components (a guide rail, a storage part, a storage rail, etc.) of the existing panel shutter apparatus.
