Description

[Detailed description of the invention] This invention relates to a rain door, more specifically, it is formed into a U-shape by bending both ends, and consists of a vertical piece in the longitudinal direction at the center of the inner surface, and a horizontal piece extending left and right from the vertical piece. A T-shaped locking ridge is provided protrudingly,
A vertical stile is provided with locking parts at both ends of the horizontal piece, and both ends are bent at right angles along the inner surface of the vertical stile, and the tip of this bent piece is placed in front of the vertical stile and horizontally. It consists of a pair of front and back steel plates that are folded inward at a position facing the front and back steel plates and provided with a folded part, and a substantially H-shaped upper and lower frame that clamps and covers the top and bottom of the steel plates, and the tip of the folded side of the front and back steel plates is Slide the vertical piece of the locking rib from one side so that it comes into contact with and locks the locking part of the locking rib of the vertical stile, and further cover the top and bottom of the steel plate with the top and bottom frames and attach it to the top and bottom frames. This method provides a storm door that is fixed to a vertical stile via a corner block, and is made by injecting foam material between the steel plates and hardening the foam.

Conventionally, shutters made of this type of steel plate, in which a vertical frame is slid onto the front and back steel plates from the upper or lower part, are made by folding a pair of front and back steel plates a whose ends are tilted and folded back, as shown in Figure 1. Arrange the pieces, b, in correspondence, and fold this folded piece, b
A receiving strip d protruding from the center of the inner surface of a vertical stile C whose both ends are bent at right angles is inserted into the gap at the tip of the vertical stile C. The tip of the folded piece from the steel plate a is locked to the taper locking part e, or the rear part of the bulge at the tip of the receiving strip d' shown in FIG. A pair of steel plates a/, which are obtained by bending the ends of the receiving strips d' of the vertical stile C' at a right angle, and then folding the ends of the bent pieces at an angle, form a pair of steel plates a/, and opposing folded pieces b of a/. There are some types that can be slid into the gaps between ' and b', but in both cases, the receiving strips are locked at the hook-shaped bulges, so the distance between the locking parts is narrow.

Therefore, when the receiving strips d and d' of the vertical stile C9C' are slidably fitted, the distance between the folded portions of the steel plates and b cannot be made large.

Therefore, the workability is poor, and as shown in Figure 3, the vertical stile is slid into place, and in order to connect this vertical stile to the upper and lower stile f, a part of the upper and lower sides of the side walls of the vertical stile are cut out and abutted. In order to communicate with each other, there may be a misalignment between the vertical stile and the upper and lower stiles.

The present invention deals with this problem in view of the above points.
That is, the locking portion of the locking striation protruding from the center of the inner surface of the vertical stile,
It is provided at both ends of the horizontal piece extending from the vertical piece to the left and right, and by increasing the distance between the locking parts, the gap between the bending points of the folded pieces of the front and back steel plates can be increased, simplifying the sliding fit of the vertical stile, and further making it possible to The purpose of this is to fit the corner blocks of the upper and lower frames to prevent misalignment during assembly and improve work efficiency.

An embodiment of the shutter according to the present invention will be described in detail below with reference to the accompanying drawings.

1 is a vertical stile formed into a shape by bending both ends at right angles, and a vertical stile 2 and a horizontal piece 3 extending from the vertical piece 2 to both sides in the longitudinal direction of the inner surface of the vertical stile 1 form a T-shape. A locking ridge 5 formed in the shape of a locking rib 5 is provided in a protruding manner, and both ends of the horizontal piece 3 are bent toward the inner surface of the vertical stile 1 with an inclination to form a locking portion 4.

The upper and lower ends of the locking rib 5 are cut out so that corner blocks 8 and 9 attached to both ends of an upper stile 6 and a lower stile 7, which will be described later, can be fitted into the vertical stile 1.

Both the upper stile 6 and the lower stile 7 have a substantially H-shaped cross section, and the upper and lower sides of the front and back steel plates 11 and 12, which will be described later, are sandwiched between them.

Reference numerals 8 and 9 denote corner blocks attached to the ends of the upper and lower frames 6 and 7, and the ends are bent by bending pieces 1' on both sides of the upper and lower ends of the vertical frame 1.
.

1' and tighten with screws.

Reference numerals 11 and 12 are front and back steel plates of the shutter, and both ends thereof are connected to the vertical frame 1.
A folded piece 10' is formed by bending the folded piece 10 at a right angle along the inner surface of the vertical stile 1, and tilting the tip of the bent piece 10 inward at a position in front of the vertical piece 2 from the vertical stile 1 and facing the horizontal piece 3. It is molded with.

The steel plates 11, 12 are aligned with each folded piece 1G', 10' in correspondence, so that the longitudinal piece 2 of the locking rib 5 is inserted between the folded points 15, 16, and the steel plates 11, 12 are aligned. The vertical stile 1 is slidably fitted from one side so that the corner part is received by a part of the corner of both side bending pieces 1', 1' of the vertical stile 1, and is stably fixed.

Here, the tips of the folded pieces 10' and 10' of the steel plates 11 and 12 are in contact with the locking part 4 of the horizontal piece 3 of the vertical frame 1, and the steel plates 11.
The corner portion 12 is pressed by a part of the corner of the vertical stile 1 and is stably fixed and set.

Furthermore, the front and back steel plates 11 and 12 are covered by the vertical stile 1 and the upper and lower frames 6 and 7 and fixed through corner blocks.

In addition, a foaming material 14 such as urethane is injected and foamed between the steel plates 11 and 12 temporarily assembled with this setting, and the foaming pressure causes the steel plates 11 and 12 to form on the inner surface of the vertical frame 1 and the inner surface of the bent piece 1'. It is firmly pressed into place and fixed by cooling.

The present invention has the above-mentioned structure, in which the vertical stile 1 having the locking ribs 5 vertically protruding from the center of the inner surface is folded back into pieces 10', 10.
A bent corner of the steel plate is applied to a part of the corner of the vertical stile 1 from either the upper or lower end of the longitudinal direction of the steel plates 11 and 12, which correspond to each other, and the vertical piece 2 is bent at the turning point 15.
．． The upper and lower sides of the steel plates 11 and 12 are sandwiched and covered between the H-shaped upper and lower frames 6 and 7, and the upper and lower frames 6 and 7 are assembled. are fitted and fixed to the vertical stile 1 via the corner blocks 8 and 9, and a foaming material 14 is injected and foamed between the steel plates 11 and 12 assembled in this way, resulting in foaming that spreads in all directions. The shutter is constructed by strongly pressing the steel plates 11 and 12 against the inner surface of the vertical stile 1 and the bent pieces 1' at both ends of the vertical stile 1 and fixing them by cooling. In addition, the vertical stile 1 is provided with bent pieces 1' at both ends, so that the tip of the folded piece of the steel plate can be used when installing the shutter or until the foaming material is injected and foamed. Temporary assembly is performed without coming off from the locking part of the vertical stile, and during foaming, the folded piece is strongly pressed toward the base of the horizontal piece due to the foaming pressure of the foam material, and the bent piece of the steel plate is firmly attached to the vertical stile. The steel plate is strongly pressed against the inner surface of the bent piece, and as the foam material cools and solidifies, it is firmly fixed.

In addition, due to the foaming and cold solidification of this foam material, the inside of the shutter receives equal pressure and contacts each other, so each ridgeline at the edge of the shutter is clearly established and configured, so the width, thickness, etc. of the shutter can be adjusted to exact dimensions. Since it is molded, it has the effect of making even shutters.
