Description

[Detailed Description of the Invention] The present invention relates to a device for securing a rain door and a rail, which prevents the rain door from coming off the rail due to strong winds such as typhoons.

When a house is exposed to strong winds such as a typhoon, the shutters on the side facing the wind are pushed indoors, but the shutters on the opposite side of the house are pulled toward the outdoors.

Many conventional shutters have a mechanism in which the upper and lower ends of the shutter simply fit into the upper and lower rails, respectively, to open and close laterally, but these conventional shutters do not survive strong winds such as typhoons. If it is agitated, it may deform into an arch toward the outside and cause an accident in which it may come off the rail and be scattered (see Figure 4).

In particular, when conditions such as when the rail and the shutter overlap shallowly or when the shutter is large and the area exposed to wind pressure is large, there is a high risk of this accident occurring.

In view of these points, the present invention aims to provide a locking device for the shutter and the rail, which ensures the engagement between the shutter and the rail and prevents the shutter from being blown away even in strong winds such as typhoons. This is the purpose.

The present invention will be explained below based on the embodiments shown in the drawings.
2 is a storm door main body, 2a is a substantially box-shaped upper stile attached to the upper end of the storm door main body 1, and 2b is a lower stile attached to the lower end of the shutter main body 1.

The upper stile 2a and the lower stile 2b have the same shape except that the lower stile 2b is provided with a door wheel 7 at the bottom.

The upper stile 2a has an outer plate upper end bent outward in the shape of a hook to form a downward engaging piece 3a.

The lower end of the lower stile 2b is also bent outward in the shape of a hook to form an upwardly directed engagement piece 3b having the same shape as that formed on the upper stile 2a.

Further, the lower end of the outer desk of the substantially downward U-shaped upper rail 4a into which the upper stile 2a is fitted is bent inward and upward into a hook shape to form a receiving piece 5a that engages with the engaging piece 3a of the upper stile 2a. are doing.

Street-facing U-shaped lower rail 4b that fits the lower stile 2b
A receiving piece 5b is also formed at the upper end of the outer side plate of the lower stile 2b, which is bent inwardly and downwardly into a hook shape and engages with the engaging piece 3b of the lower stile 2b.

The receiving pieces 5a and 5b have the same shape.

The upper rail 4a and the lower rail 4b are each fixed to a plate 8 or the like constituting the side part of the building with fixing members 9 such as screws.

6a and 6b are sliding members. If the receiving piece 5a formed on the upper rail 4 and the receiving piece 5b formed on the lower rail are provided in the entire longitudinal direction, the engaging piece 3b formed on the lower stile of the engaging piece 3a formed on the upper stile may be provided only in a part in the longitudinal direction, and if these engaging pieces 3a and 3b are provided in the entire longitudinal direction, the receiving piece 5a formed on the upper rail and the receiving piece 5a formed on the lower rail will be separated. The piece 5b may be provided only in a part in the longitudinal direction.

The upper and lower frames and rails are mainly made of extruded aluminum, but may also be made of other metals, synthetic resins, etc.

Incidentally, the engagement relationship between the shutter body and the rail as in the present invention is usually referred to as a seam mechanism, and FIG. 3 shows various embodiments of this seam mechanism.

In other words, this is a modified example of a retaining piece and a receiving piece that are bent into the shape of a hook.

The installation of the shutters and rails on the building is carried out by attaching the upper and lower rails and then sliding the shutters laterally between the upper and lower rails before attaching the door pockets.

The above-described device for engaging the shutter and the rail of the present invention allows the shutter to be connected to the rail by a so-called seam mechanism, even if the shutter is deformed in an arched direction outdoors due to strong winds or typhoons. Due to the meshing of the shutters, there is no risk of the shutter body separating from the rail and flying off, making the shutter extremely safe against strong winds.

Moreover, despite this safety mechanism,
The appearance of each part constituting the shutter is not impaired at all.

Moreover, since the upper stile and the lower stile have the same shape, they can be manufactured efficiently.

Moreover, since it is formed into a substantially box shape, it has high strength and can be easily attached to the shutter body.

By adhering the upper stile and the lower stile, the upper and lower ends of the shutter main body are reliably protected and made sturdy.

Since the retaining piece protrudes from such a high-strength member, it has many effects such as strong resistance to pressure and pull pressure in the left and right directions, ensuring reliable engagement between the shutter and the rail.
