Description

[Detailed Description of the Invention] This invention relates to a panel for a panel-type shutter device, which is used to shield entrances, windows, etc. of buildings, or to form partitions that can be opened and closed.

Various panel-type shutter devices have been proposed in the past, but during the closing operation of the shutter, gaps are created between each panel, and objects can enter into these gaps and cause the shutter device to malfunction, or parts of the human body may Sometimes it got caught. Furthermore, with conventional frame materials, especially in the case of long ones, smooth engagement may not be achieved due to ``deflection'' or ``twisting'' of the frame material, and the strength of the engagement itself may become unstable. It was hot.

This invention solves the above-mentioned drawbacks, and enables smooth and strong interlocking engagement between each panel when the shutter is closed.
Another object of the present invention is to provide a panel portion of a panel type shutter device that shields gaps between panels to prevent objects from entering the gaps and personal injury.

An embodiment of this invention will be described below with reference to the drawings.

As shown in the first diagram, a panel type shutter device 1 is installed at the entrance, exit, window, etc. of a building, and a plurality of panels 6 are formed by an opening/closing machine 2 via a chain 3 so as to be movable up and down along guide rails 4 and 5. ing.

The plurality of panels 6 are stored in a folded state in a storage box (not shown) at the back of the opening/closing machine 2 when opened.

On the other hand, when the shutter is closed, the panels 6 are pulled out one by one from the storage box by the lifting and lowering of the chain 3, and as shown in the second figure, are connected in a sheet form to an entrance or exit of a building to ensure the closed state. .

Each panel 6 that is raised and lowered one by one is shown in Figures 1 and 2.
As shown in the figure, it has a frame consisting of a vertical frame 7 and a horizontal frame 8 connected to the vertical frame 7 by ordinary means, and the panel surface 9 is firmly fixed, and intermediate reinforcing members 10 are arranged at predetermined intervals. has been done. This invention is characterized in that the upper frame 8a and lower frame 8b of the horizontal frame 8 have a special shape.

Hereinafter, although there are a plurality of panels 6, for the sake of convenience, three panels will be described: an upper adjacent panel 6B, a panel 6A, and a lower adjacent panel 6C.

That is, the upper frame 8a of the horizontal frame 8 of the panel 6A has a second
As shown in FIG. 3, first and second upper frame extensions 11 and 12 are provided to protrude upward.

The first upper frame extension part 11 is formed to extend upward on the outdoor side of the upper frame 8a so as to be able to cover the vicinity of the outdoor side lower frame part of the upper adjacent panel 6B when the shutter is closed. ing. An airtight material 13 made of, for example, soft vinyl chloride is installed at the tip of the first upper frame extension 11 to take measures against rain and to ensure airtightness. Also,
The second upper frame extension part 12 is formed to extend upward on the indoor side of the upper frame 8a, and guides the upper adjacent panel 6B as described later.

On the other hand, as shown in FIGS. 2 and 4, the lower frame 8b of the panel 6A is provided with a wall on the indoor side of the lower frame 8b and below, so that the vicinity of the upper frame of the lower adjacent panel 6C can be covered when the shutter is closed. A lower frame extension portion 14 is formed to extend toward.

Further, the indoor side of the lower frame 8b is in contact with the second upper frame extending portion 12 of the lower adjacent panel 6C, and the second upper frame extending portion 12 of the panel 6A is connected as shown by the arrow in FIG. An inclined recess 15 is formed as a guide portion to guide the panel to a predetermined engagement position and to reliably engage the upper frame 8a and lower frame 8b of adjacent panels.

According to the above configuration, the shutter is supported by the guide rail (not shown), and when the shutter is in the closed state,
As shown in FIGS. 1 to 4, the panels 6A, 6B, and 6C are in close contact with each other without any gaps, and even during the opening/closing operation, the upper frame 8a and the lower frame 8b of the panels 6A, 6B, and 6C are mutually connected. It fits perfectly and looks good when viewed from the front as there are no gaps. In addition, during the closing operation of the panel 6A, the lower frame 8
Since the inclined recess 15 is formed in b, this inclined recess 15 comes into contact with the second upper frame extension 12 of the lower adjacent panel 6C, guides the lower frame 8b to a predetermined engagement position, and closes the frame. To prevent defects in the meshing engagement between the lower frame 8b and the upper frame 8a of adjacent panels 6A and 6C due to material deformation (bending, twisting, etc.) and to strengthen the engagement between both frames 8a and 8b. I can do it.

Furthermore, even if a gap 16 occurs between the panels 6A and 6C as shown in the fourth diagram, the adjacent panels 6A and 6C
This gap 16 is covered by extensions 11, 12, and 14 extending from the upper frames A and 6C and the lower frames 8a and 8b, respectively, as shown in the fourth figure. Therefore,
Objects will not enter this gap 16 and cause a failure of the shutter device, and a part of the human body such as a finger will not be caught in this gap. Further, during the closing operation, if the bottom panel stops with only the bottom panel in contact with the floor surface, the condition of the panels becomes as shown in FIG. 4, and some ventilation becomes possible.

As described above, according to this invention, it is possible to smoothly and reliably engage adjacent panels when the shutter is closed, and to strengthen the engagement between each panel.
Moreover, it has extremely excellent effects such as being able to shield the gaps between each panel and prevent breakdowns and personal accidents caused by objects entering the gaps.
