Description

[Detailed explanation of the idea] The present invention relates to an insulating storm door.

When forming conventional insulated storm shutters, a front panel A and a back panel B are overlapped with a heat insulating material interposed between them.
A heat-insulating storm door is known in which the ends 1 and 2 of both panels A and B are bent toward the opposite panel side, overlapped, and housed in a mounting groove 3 in the form of a groove with a lip in a vertical stile 4. ing.

However, in order to form a conventional insulating rain door, as shown in Fig. 4, the ends 1 and 2 of both panels must be assembled by sliding them into the mounting groove 3 of the vertical stile 4 from the top. , it was extremely labor-intensive.

The present invention has been devised to address these conventional problems, and will be explained below based on embodiments shown in the drawings.

FIG. 1 is a front view showing an insulating rain door C according to the present invention, and FIG. 2 is a cross-sectional view thereof.

In the drawings, symbol A indicates the front panel, and symbol B indicates the back panel. Both panels A and B have a groove 5 extending in the vertical direction approximately in the center thereof. Further, a plurality of vertical grooves 6 are formed on both end sides of both panels A and B, respectively, as a decorative pattern on the panel surface.

The front panel A and the back panel B are connected via a heat insulating material 7 and a heat insulating foam 19 which also serve as baseboards.

By the way, both panels A and B are fixed by fitting the ends of both panels A and B into the mounting grooves 3 of the vertical stile 4.

Next, the fitting and fixing will be explained with reference to FIG.

In FIG. 3, reference numeral 4 is a vertical frame, and the vertical frame 4
has a mounting groove 3 on the inside. This mounting groove 3 is formed in the shape of a concave groove having lips 8,8.

Reference numeral A designates the front panel, which has a convex curved portion 9 at its right end when viewed from the drawing. Further, a bent portion 10 having substantially the same shape as the convex curved portion 9 is formed at the left end. Further, from this bent portion 10, an overhanging piece 12 is provided that extends substantially perpendicularly to the base 11 of the front panel A, and from this overhanging piece 12, a convex curved portion of the back panel B, which will be described later, is provided. 9 has a predetermined space P, and two points X, Y
A second convex curved portion 13 is extended, which abuts at.

The left end of the back panel B has a convex curved part 9 that engages and contacts the second convex curved part 13 of the front panel A, and the right end has a bent part 9. part 10, overhang piece 12 and second convex curved part 1
3 is formed similarly to the front panel A.

In this way, bulging portions D and D that bulge outward are formed at the ends of both panels A and B, and a flange-like fitting portion E is formed as a whole.

Note that the front panel A and the back panel B can be used as the same panel if they have the same shape and one of them is used with the left and right sides reversed.

In the above process, the brim-like fitting portion E is pushed into the mounting groove 3 of the vertical stile 4 from the opening F side toward the bottom wall 14 side of the mounting groove 3. Then, this brim-shaped fitting portion E comes into contact with the lips 8, 8 of the mounting groove 3, elastically contracts inward, and fits into the mounting groove 3. Mounting groove 3
After being fitted into the interior, the brim-like fitting portion E elastically expands, and the ends of both panels A and B are fixed to the vertical frame 4.

That is, as shown in FIG. 5, the bent portion 10 of the front panel A is in contact with the inner surface of one side wall 15 in the mounting groove 3, and the resistance is exerted by the second convex curved portion 13 of the front panel A. is transmitted to. This second convex curved portion 13 is in contact with the inner surface of the convex curved portion 9 of the back panel B at two points, X and Y, so that the convex curved portion 9 of the back panel B is Resilient mounting groove 3
It comes into contact with the other side wall 16 of.

Thereafter, a heat insulating foam is filled between the front panel A and the back panel B to finally form a heat insulating shutter C.

This heat insulating storm door C has the same shape on both sides, so that the back side can be used as the front side. Further, a recess 5 is formed approximately in the center of the back panel B, and a lock 18 is provided within this recess 5.
will be installed. A recess 5 must be formed in the approximate center of the front panel A, but when used as the front panel A, it is usually covered with a cover 17.

Thus, the present invention has the above configuration, and the insulating rain door according to the present invention allows the insulating rain door to be assembled extremely easily, and also provides a strongly connected insulating rain door.
