[0011]

[Embodiment] An embodiment of this invention will be described below with reference to the drawings. As shown in FIG. 1, a panel type shutter device 1
are installed at entrances, windows, etc. of buildings, and are configured such that a plurality of panels 6 are moved up and down along guide rails 4 and 5 via a chain 3 by an opening/closing machine 2.

[0012] The plurality of panels 6 are stored in a storage box (not shown) on the back of the opening/closing machine 2 when opened.
It is stored folded inside.

[0013] On the other hand, when the shutter is closed, the panels 6 are pulled out one by one from the storage box as the chain 3 moves up and down, and as shown in FIG. Secured.

[0014] Each panel 6, which is raised and lowered one by one, has a frame consisting of a vertical frame 7 and a horizontal frame 8 connected to this by ordinary means, as shown in FIGS. 1 and 2. The surface 9 is firmly fixed, and intermediate reinforcing members are arranged at predetermined intervals.

[0015] This invention is based on the upper frame 8a of the horizontal frame 8.
It is also characterized in that the lower frame 8b has a special shape.

[0016] Hereinafter, there will be a plurality of panels 6, but here, for convenience, the upper adjacent panel 6B, the panel 6A,
This will be explained using three panels, which are the lower adjacent panels 6C.

[0017] That is, the upper frame 8a of the horizontal frame 8 of the panel 6A
As shown in FIGS. 2 and 3, first and second upper frame extensions 11 and 12 are provided to protrude upward.

[0018] The first upper frame extension part 11 extends upward on the outdoor side of the upper frame 8a so that the vicinity of the outdoor lower frame part of the upper adjacent panel 6B can be covered when the shutter is closed. It is formed.

[0019] As shown in FIG. 3, an airtight material (packing) 13 made of, for example, soft vinyl chloride is attached to the tip of the first upper frame extension 11.

[0020] This packing 13 is connected to the outdoor side wall surface of the lower frame portion 8b of the upper adjacent panel 6B and the panel 6.
The space between the first upper frame extension part 11 of A and the first upper frame extension part 11 is sealed to perform a rain protection function.

[0021] Further, 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.

[0022] Here, the second upper frame extension part 12
The height dimension is approximately 1/2 compared to the first problem 11.
It is formed short so that

[0023] A fitting recess 80 is formed between the first upper frame extension part 11 and the second upper frame extension part 12.
A bottom surface 80a of this fitting recess 80 is formed.
is entirely flat.

[0024] Therefore, the fitting recess 80 has a depth corresponding to the height dimension of the second upper frame extension 12.

On the other hand, at the lower part of the lower frame 8b of the panel 6A, as shown in FIGS. 2 and 4, there is a fitting bottom 81 that is convex downward when the shutter is closed, and an upwardly inclined guide that is connected to the fitting bottom 81. When the shutter is closed, the second upper frame extension 12 of the lower adjacent panel 6C is brought into normal engagement while being guided in contact with the upwardly inclined guide wall 15a as shown by the arrow in FIG. An engagement recess 15 for fitting and engaging in the mating position is integrally formed.

[0026] This engagement recess 15 is shown in FIGS. 3 and 4.
As shown in FIG. It is composed of an upright wall 15d parallel to the wall, and is formed in an inverted U-shape that loosely fits above the second upper frame extension part 12.

[0027] As described above, the engagement recess 1 has an inverted U-shape.
5 sandwiching the upper part of the second upper frame extension part 12 in a loose-fitting manner, the engagement recess 15 reliably prevents displacement due to parallel movement and rotation of the second upper frame extension part 12. To prevent.

[0028] In addition, the lower frame 8b of the panel 6A is provided with a lower frame on the indoor side of the lower frame 8b and toward the bottom so that the vicinity of the upper frame of the lower adjacent panel 6C can be covered when the shutter is closed. The extending portion 14 is formed to extend.

Furthermore, an outwardly protruding edge 82 (see FIGS. 3 and 4) that presses the gasket 13 from above when the shutter is closed is integrally formed at the upper end of the lower frame 8b of the panel 6A on the outdoor side. There is.

[0030] On the lower surface of the outer end of the outwardly protruding edge 82, the packing 13 is attached when the shutter is closed.
A downward engaging protrusion 82a is integrally formed to grip the upper end of the gasket 13 and prevent the gasket 13 from escaping outward.

[0031] When the shutter is closed, the engaging protrusion 82a grips the upper end of the packing 13 pressed from above by the outwardly protruding edge 82 and prevents the packing 13 from escaping outward. In order to prevent this, the packing 13 has the outwardly projecting edge 82
The lower frame 8 of the upper adjacent panel 6B below
The outdoor side wall surface of b and the first upper frame extension part 11 adjacent to the wall surface are firmly compressed to reliably seal the space between them. In FIG. 3, 82b is a small space formed behind the gasket 13 at the lower part of the outwardly projecting edge 8 (on the wall surface side on the outdoor side of the upper adjacent panel 6B). 82b helps prevent the packing 13 from shifting outward.

[0032] According to the above configuration, each panel 6A, 6B, 6C is supported by the guide rails 4, 5, and in the closed state of the shutter, each panel 6A, 6B, 6C is
As shown in the figure, they are brought into close contact with each other without any gaps,
Even during the shutter opening/closing operation, the panels 6A, 6
The upper frame 8a and the lower frame 8b of B and 6C fit together, and there is no gap when viewed from the front, so the appearance is good.

[0033] In addition, an inclined guide wall 15a is attached to the lower frame 8b.
Since the engagement recess 15 is formed in an inverted U-shape, during the closing operation of the panel 6A, the second upper frame extension 12 of the lower adjacent panel 6C is attached to the inclined guide wall 15a. are brought into contact with each other, and the upper frame extension portion 12 is guided and engaged with the engagement recess 15 .

[0034] As a result, the lower frame 8b of the panel 6A and the upper frame 8a of the lower adjacent panel 6C are guided and aligned to the normal engagement position, so that there is no interference due to deformation (bending, twisting, etc.) of the frame material. Adjacent panels 6A, 6C
It is possible to prevent malfunctions in the meshing engagement between the lower frame 8b and the upper frame 8a, and moreover, both frames 8a,
8b to securely and firmly engage each other.

[0035] In the shutter closed state shown in FIG. 3, the gasket 13 is pressed from above by the outwardly protruding edge 82 of the upper adjacent panel 6B, and the engagement protrusion 82a of the outwardly protruding edge 82 grips the tip of the gasket 13, so the gasket 1
3 does not escape outward, and is firmly compressed to reliably seal the space between the outdoor side wall surface of the lower frame 8b of the upper adjacent panel 6B and the first upper frame extension part 12.

[0036] Furthermore, as shown in FIG. 4, even if a gap occurs between each panel 6A, 6C, the extensions formed to extend from the upper frame 8a and lower frame 8b of the adjacent panels 6A, 6B, respectively. 11, 12, and 14, the outdoor side and indoor side of the gap 16 are reliably shielded. Therefore, objects will not enter the gap 16 and cause the shutter device to malfunction, and a part of the human body such as a hand or finger will not be caught in the gap, improving safety.

[0037] Furthermore, during the shutter closing operation, if the shutter stops with only the bottom panel in contact with the floor surface, the panels will be in the state shown in FIG. 4, and some ventilation will be possible.

[0038] In the above embodiment, each panel 6, 6A, 6B, 6C has its outdoor side and indoor side reversed, that is, the first upper frame extension part 11 side is the indoor side, Moreover, it is also possible to use the second upper frame extension part 12 with the second upper frame extension part 12 on the outdoor side, and with them facing downward (upside down from the illustrated state).

【0039】

[Effects of the Invention] As described above, according to this invention, a gasket for sealing the gap with an upper adjacent panel is attached to the upper end of a first upper frame extension part that extends upward on one side of the upper frame of a panel that rises and falls in a state adjacent to one another vertically along a guide rail when the shutter is opened and closed, and an outwardly protruding edge part that presses against the gasket when the shutter is closed is integrally formed with the lower frame of the upper adjacent panel, and a gasket is provided on the underside of the outer end part of the outwardly protruding edge part that grips the upper end of the gasket when the shutter is closed, thereby sealing the gasket. Since a downward engaging protrusion that prevents the gasket from escaping outward is integrally formed, when the shutter is closed, as described above, the engaging protrusion grips the upper end of the gasket that is pressed from above by the outward protruding edge, preventing the gasket from escaping outward, so that the gasket is firmly compressed between both the exterior wall surface of the lower frame of the upper adjacent panel below the outward protruding edge and the first upper frame extension portion adjacent to said wall surface, thereby reliably sealing the space between them.

[0040] In addition, in this invention, the bottom frame of the panel has a downwardly convex fitting bottom, an upwardly inclined panel wall connected to this fitting bottom, and a downwardly adjacent panel wall connected to the inclined guide wall when the shutter is closed. 2nd panel
Since an inverted U-shaped engagement recess that loosely fits the upper frame extension is provided, when the shutter is closed, the engagement recess fits above the second upper frame extension in a loose fit. By sandwiching the upper frame extension portion, it is possible to reliably prevent displacement due to parallel movement and rotation of the upper frame extension portion.
