Description

[Detailed description of the invention] This invention relates to a decorative board that is constructed by stacking multiple boards and connecting them vertically.By devising the connection structure of each board, the invention is strong and airtight. To provide a decorative board which has a high hardness, can reliably prevent the intrusion of rainwater, has an excellent appearance, and is suitable for shutters of shutters, wainscoting of houses, etc.

First, one embodiment of the present invention will be explained based on the drawings.
Fig. 1 shows an example in which the decorative board of the present invention is applied to the door pocket 1 of a storm door. Plate bodies 3, 4...
For example, a composite plate in which polyethylene is sandwiched between two thin aluminum plates is used.

However, of course, colored iron plates, PVC steel plates, etc. can also be used.

As shown in FIG. 2, the plates 3, 4, . . . are vertically connected in series in a stacked configuration slightly inclined with respect to the vertical direction.

In other words, if we were to comment on this connecting part, the upper plates 3, 4,
. . . The lower end portions are folded inward at an acute angle, and the plate bodies 3, 4, . . .
The lower plate body 4゜5 to be connected to...
. . . upper ends 4b, 5b... whose outer surfaces are overlapped, and the overlapped upper ends 4b, 5b... and the folded portions 3a, 4a... A picture frame 8 made of aluminum, for example, which is bent into a U-shaped cross section is placed from above, and in this state, the lower end of the upper plate, the upper end of the lower plate, and the frame 8 are placed.・It is crimped by driving rivets etc.

The rivets are shown in Figure 3 so that they are not visible from the outside as much as possible.
, It is desirable to drive it toward the left and right side edges hidden by the door bag frame 2, as shown by f.

In the figure, 2a and 2b are mounting pieces extending from the door frame 2 at a position slightly recessed from the front end of the door frame 2;
, f are driven through the mounting pieces 2a, 2b and both ends of the connecting portion, and the plates 3, 4...
The plates 3, 4, etc. are fixed to the door bag frame 2 at the same time as they are crimped.

The lower end of the plate is cut from the inner surface as shown by P in FIG. 2, and is folded back at an acute angle.

Here, "acute" means that the corner indicated by q in the figure is not rounded and is sharp.

In addition, the upper end of the uppermost board 3 constituting the decorative board is the door bag frame 2.
It is attached to the upper mounting piece with rivets.

Although not shown, the lower end of the lowermost plate has a similar structure and is fixed to the mounting piece.

Although this embodiment shows an example in which the decorative board of the present invention is applied to the door pocket of a storm door, it can also be applied to other materials such as the wall surface of a house or the wainscoting of a shoji screen.

Since the decorative board according to the present invention is constructed as described above, it has the following advantages.

■ A plurality of plate bodies 3, 4... are stacked and connected vertically, and each plate body 3, 4...
Since the connection is made by overlapping the lower end of the upper plate and the upper end of the lower plate, each connected part becomes a knot and is strong.

That is, it is strong against external forces acting in a direction perpendicular to the plate surface.

Therefore, it is particularly suitable for shutter shutters, wainscoting for houses, etc. that are exposed to strong winds such as typhoons.

Also, since it is strong, each board can be made sufficiently thinner than a single decorative board.

■ Since the lower end of the upper plate is located on the outside and the upper end of the lower board is located on the inside, the path for rainwater to enter can be lengthened, and there is a risk that rainwater may enter the inside from the overlapped part. There is no.

■ The lower end of the upper plate is folded back inward, and the folded parts 3a, 4a... and the upper end 4 of the lower plate
b.

5b.... are overlapped and the picture frame 8 is placed on top of the frame 8 and then tightened, so it has high airtightness, and in addition to the advantages mentioned in ①, it can be used even in windy weather or heavy rain. Entry of rainwater is reliably prevented.

(2) Since the folded portions 3a, 4a, . . . have acute angles, the paint will not peel off.

That is, if the folded part is rounded, the paint will peel off when folded, but if the folded part is at an acute angle, there will be no such drawback.

Therefore, since the paint can be sprayed first, secondary processing can be performed, and thicker coatings can also be applied.

■ The plates are lined up in a static state with the top end facing inside and the bottom end facing outside, and the paint on the folded parts has not peeled off, making it an excellent design.

Claims (1)

[Scope of utility model registration request] A decorative board that is made by stacking a plurality of boards and connecting them vertically and fixing them within a door frame, wherein each of the boards is connected to each other by turning the lower end of the upper board inward at an acute angle. A folded part is formed by folding the folded part, and the outer surface of the upper end of the lower plate is superimposed on the folded part, and a new frame having a U-shaped cross section is added from the superposed upper end and above the folded part. The connecting portion is tightened and fixed, and both ends of the connected portion thus crimped are fixed to a mounting piece extending from the door frame at a position slightly recessed from the front end of the door frame. Features a decorative board.
