Description

[Detailed explanation of the idea] This idea concerns metal shutters.

Conventionally, as a panel mounting structure for a storm door, a panel mounting structure is known in which the panel is mounted to a mounting piece of a rectangular frame surrounding frame, and a middle crosspiece is riveted to the back surface of the panel.

Generally, the panels used for metal shutters are thin metal plates that have a strong shape, so these metal plates tend to bend in a wavy manner. Not only is installation troublesome, but simply installing the shutters can cause the shutters to rattle due to the wind pressure from outside and sometimes cause the panels to peel off after many years of use.

This idea was devised to eliminate the above-mentioned drawbacks of the conventional methods, and its purpose is to provide high mounting strength even when the panel is a thin metal plate, and to allow the panel to be easily mounted without bending. The goal is to provide a structure for shutters that can be used.

This invention will be explained below based on embodiments shown in the drawings.

FIG. 2 is a cross-sectional view showing the structure of the shutter according to this invention.

In FIG. 2, reference numeral 5 indicates a middle crosspiece.

This middle crosspiece 5 is attached in advance to the back surface of the panel B with an adhesive.

In the embodiment shown in FIG. 3, one middle crosspiece 5 is attached, but
As in the embodiment shown in FIG. 5, a plurality of middle crosspieces 5 may be attached to the back surface of the panel B.

Further, as shown in FIG. 2 or FIG. 6, the panel B is bent such that its panel ends 6, 6 wrap around both ends 7, 7 of the middle crosspiece 5.

By bending the panel ends 6, 6 of panel B in this way, a central crosspiece panel in which panel B and central crosspiece 5 are integrated is formed, and the surface of panel B is given tension and deflection is prevented. Try not to let it happen.

Furthermore, notches 8, 8 are provided at both ends 7, 7 of the middle crosspiece 5,
By tightening both ends 6.6 of the panel B into the notches 8, 8 with a punch or the like, the surface tension of the panel B is further increased, and a storm door with excellent integrity between the panel B and the middle crosspiece 5 is created. We will be able to provide the following.

Further, in FIG. 2 of the drawing, reference numerals 1 and 1 indicate the vertical frame of the shutter A.

The vertical stiles 1, 1 extend from the facing parts of the vertical stiles 1, 1 to the indoor side, and are bent toward the bases 2, 2 of the vertical stiles 1, 1. 3 each.

The middle crosspiece panel is attached across these indoor side mounting pieces 3, 3, and the middle crosspiece panel is attached to the vertical frame 1.degree. 1 by connecting tools 4 such as rivets.

Incidentally, the attachment of the middle frame panels using the connectors 4 may be performed at appropriate intervals in the longitudinal direction of the vertical stile 1.

This invention has the above-mentioned configuration, and in the shutter of this invention, the panel ends are bent at both ends of the middle crosspiece to wrap around the middle crosspiece, and are crimped into the notches of the middle crosspiece, so that the panel and the middle The crosspieces form a central crosspiece panel that is integrated with the crosspieces.

In addition, the panel becomes flat without waving by simply crimping, and an inexpensive storm door can be easily obtained without using screws or the like.

In addition, since there is no bending, it can be attached closely to the mounting pieces of the surrounding frame and will not wobble.
