Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a panel shutter composed of a plurality of panels that are connected and suspended by a chain or the like.

[0002]

[Prior art]

 The panel shutter connects multiple panels at each end with a chain, etc., and the chains support the tops of both ends of the panel. Each panel is guided along a pair of guide rails on both sides of the building's opening.

Then, by winding up the chain by the drive unit located above the guide rails, the upper parts of the respective panels are suspended in the storage box continuously arranged at the upper ends of the guide rails. It is configured to be stacked and stored in the front-back direction in the closed state.

A plurality of panels constituting a panel shutter are continuously and substantially integrally connected vertically between guide rails of a building opening when the shutter is closed. In this connection, upper and lower frames of each panel are mutually connected. By fitting them together, the independent panels are joined together almost in one piece, and when the shutter is closed, the fitting cannot be easily released.

In addition, on these panels, guide rollers or guide pins are provided in the vicinity of the lower edges on the back surface side at both left and right ends, and the left and right walls of the storage box in which these panels are stored are installed. In the vicinity of the guide rail of the bracket fixed to the inner surface, a guide plate formed in a substantially groove shape curved by a plate material is provided.

When the panels are moved, that is, when the panels are opened and closed, and when the panels are brought out of the storage box and closed, the guide rollers are engaged with the guide plates, and the guide plates are brought into contact with each other. The panel is guided from the horizontal movement in the storage box to the vertical movement to the guide rails, and at the time of the opening operation in which each panel is loaded into the storage box, the guide roller of the panel is placed on the guide plate from below. By engaging and being guided, each panel is converted from vertical ascending movement by the guide rail to horizontal movement, and is sequentially stored in the storage box.

[0007]

[Problems to be solved by the device]

 However, in the above-mentioned conventional panel shutter, each panel is configured to be suspended from the upper portions at both left and right ends, and the lower portion of the panel is a free end, so that each panel is likely to swing in the front-back direction. There are drawbacks. This swinging of the panel occurs when it receives wind pressure from the outside, or when the panel is operated by "inching" in which the operation and stop are repeated in a short time.

As a result, the guide rollers in the lower part of the panel may not engage with the guide plate of the storage box when the panels are operated, that is, when the panels are carried out and carried in by opening and closing operations. However, there is a problem that the panels are not properly guided and each panel is not loaded or unloaded correctly.

Further, from this fact, when the panel does not carry out in the vicinity of the doorway of the storage box or blocks the movement without being carried in, if the drive mechanism is in operation in this state, a load is applied to this drive system. Therefore, there is a problem that the drive mechanism may be damaged.

Therefore, in order to solve the above-described problems, the present invention is a panel shutter that can smoothly and accurately move each panel of the panel shutter when the panel is carried in or out of a storage box. Is intended to provide.

[0011]

[Means for Solving the Problems]

 Next, means for achieving the above object will be described with reference to the drawings corresponding to the embodiments. The panel shutter 1 of the present invention is a panel shutter in which a plurality of panels 2 are vertically connected and suspended, and a pair of upper and lower inner members 8 to be projected are provided at at least one end of each panel 2. , 9 and the guided members 8, 9 in the storage portion 13 in which the respective panels 2 are stored are disposed on the inner surface 13a of the side wall corresponding to the guided members 8, 9 and come into contact with the guided member 8 above the panel 2. Together, the first guide portion 21 that supports and guides the vertical movement of the panel 2 and the second guide portion that engages with the guided member 9 at the lower portion of the panel 2 and guides the moving direction of the panel 2. And a guide member 20 including a portion 22.

[0012]

[Action]

 The upper guided member 8 of the pair of upper and lower guided members 8 and 9 projectingly provided at the end portions of the plurality of panels 2 suspended by connection is a guide provided on the inner surface 13a of the side wall in the storage portion 13. The lower guided member 9 which is brought into contact with the first guide portion 21 of the member 20 and is guided to move up and down, and which is protruded from the end portion of the panel 2 is connected to the second guide portion 22 of the guide member 20. Then, the moving direction is guided. As a result, even if the panel 2 swings in the storage box when the panel 2 is unloaded, that is, when the panels 2 are closed, the swinging of the panel 2 is restricted and the panel 2 is locked. The panel 2 is stably supported in a vertically suspended state, and the movement direction of the panel 2 is guided, and the panel 2 is moved to the guide rail 12.
