Description

[Detailed Description of the Invention] This invention relates to an improvement of a metal rain door that allows easy replacement and installation of the plate.

Conventional metal shutters are made by attaching thin-walled steel plates to the upper and lower frames and left and right frames that are extruded from a light metal material, so it takes a long time to transport the shutters to the store and install them on the building. During use, or after being installed on a building, the thin panels often become uneven or damaged during use of the shutters.

However, even if the panels become uneven or damaged, because the shutters are assembled and completed at the production factory, it is inconvenient that only the panels can be replaced unless the upper and lower stiles and the left and right stiles are separated.

Therefore, this idea was designed so that after assembling the shutter frame with the upper and lower stiles, left and right stiles, and the outer crosspieces, the plate could be fitted to the frame, and at the same time, a push-edge could be attached to the vertical stiles of the frame to which the plates had been fitted. A pushpiece is attached to the middle crosspiece, and the plate body can be easily replaced by attaching and removing the pushpiece and the pushpiece.

Next, the structure of the proposed shutter will be explained using drawings of examples.
1 is a vertical stile with a butt groove 1a on the doorstop surface 1A; 2
is a vertical stile in which a protrusion 2a is provided on the doorstop surface 2A to fit into the groove 1a of the vertical stile 1, and when the vertical stile 2 is assembled on the right side,
The vertical stile 1 is assembled on the left side, and the indoor wall 1 of the left vertical stile 1
A connecting wall 1D provided between B and the outdoor side wall 1C faces a connecting wall 2D provided between the indoor side wall 2B and the outdoor side wall 2C of the right vertical stile 2, and both connecting walls ID, the indoor side 1d of 2D, It is formed in a step shape so that the space between 2d and 2d is wider than the space between 1d' and 2d' outside the room, and protrusions IE and 2E that slightly extend from the walls 1B and 2B on the indoor side are provided on the inside 1d and 2d of the room, and Outside room 1
Projections IF extend from the outdoor side wall 1C92C at d' and 2d' and protrude longer than the projections IE and 2E.

It has 2F.

4 is a lower stile formed deeper than the upper stile 3 to accommodate the door roller 9; the lower stile 4 is assembled facing the upper stile 3, and the connecting portions 3D and 4D of the opposing upper and lower stiles 3 and 4 are connected to each other; Inside, inner wall 3
A locking piece 3F that protrudes locking portions 3E, 4E that slightly extend from the locking portions 3E, 4B, extends from the outer walls 3C, 4C on the outdoor side of the connecting portions 3D, 4D, and protrudes longer than the locking portions 3E, 4E;
It has 4F.

Reference numeral 5 denotes a middle crosspiece assembled between the left and right stiles 1 and 2, and the middle crosspiece 5 has shaft parts 5F and 5F on the left and right indoor sides of the hollow body part 5A, and has a substantially T-shaped cross section.

(2) is a shutter frame assembled by the upper and lower frames 3 and 4, the left and right frames 1 and 2, and the middle frame 5.

Reference numeral 6 denotes a plate made of a thin steel plate that fits from the indoor side to the outdoor side of the shutter frame (1), and the plate 6 has a lower end bent into an L shape to form a bending piece 6b, and a bending piece 6b at the upper end. A refracting piece 6a symmetrical to the piece 6b is provided, the upper refracting piece 6a faces the connecting part 3D of the upper stile 3, the lower refracting piece 6b faces the connecting part 4D of the lower stile 4, and the upper part 6A of the plate faces the connecting part 4D of the upper stile 3. The lower part 6B of the plate body contacts the locking piece 4F of the lower stile 4, and the left and right sides of the plate body 6 touch the protruding pieces IF and 2F of the left and right vertical frames 1 and 2.

Reference numeral 7 denotes a ridge that irremovably fixes the plate 6 fitted to the shutter frame (■). It is attached to the vertical frames 1 and 2 with screws 10.

Reference numeral 8 is a plate fixed to the indoor side of the middle frame body 5A, and both ends of the plate 8 face the sleeves 5F, 5F of the middle frame 5, and the sides of the plate 6 that fit into the frame ■ are attached. It is fixed from the indoor side so that it cannot be removed.

In addition, the upper and lower stiles 3 and 4, the left and right stiles 1 and 2, the middle crosspiece 5, and the rim 7
, each of the 8 gods are extruded from aluminum or aluminum alloy.

Since the proposed storm door has the above-mentioned structure, when assembling it, first assemble the shutter frame ■ with the upper and lower frames 3 and 4, the left and right frames 1 and 2, and the outer crosspiece 5. Boards 6, 6 between the crosspieces 5 and between the right vertical stile 2 and the middle crosspiece 5
' are inserted from the indoor side, and fitted to the connecting walls 1d', 2d' of the left and right vertical frames 1, 2 up to the shaft part 5F of the middle crosspiece 5, and the upper and lower bending pieces 6a, 6b to the connecting parts 3D, 4D of the upper and lower frames 3, 4, and the upper and lower parts 6A, 6B of the plates 6, 6' to the locking pieces 3F, 4F of the upper and lower frames 3, 4,
In addition, one side of the plates 6, 6' is attached to the projecting pieces IF, 2F of the vertical frames 1, 2.
Then, after touching the other side part to the shaft part 5F of the middle frame 5, the left and right vertical frames 1
, 2 are fitted into the connecting wall chambers 1d and 2d, and these are fixed with screws 10, while the god 8 is attached to the indoor side of the middle crosspiece 5 to complete the assembly.

The ridges 7 and 8 that irremovably fix the sides of the plates 6 and 6' press the upper bending piece 6a of the plate 6 and 6' against the connecting part 3D of the upper stile 3 at their upper ends, and The lower bending pieces 6b of the plates 6, 6' are pressed against the connecting portion 4D of the lower stile 4.

Therefore, in the proposed storm door, first assemble the frame with the upper and lower frames, the left and right frames, and the middle frame, then fit the plate from the indoor side of the frame, and insert one side of the plate fitted into the frame into the indoor side of the frame. Since it is fixed with a ribbed edge that fits into the frame, and the other side is fixed with a brace attached to the indoor side of the middle crosspiece, it not only simplifies the assembly work of the storm door, but also makes it easier to assemble the shutter during transportation. Alternatively, even if the plate becomes uneven or damaged while the shutter is in use, it can be easily replaced with a new plate by simply removing the ribbed edges and shutters.

Moreover, since no special tools or skills are required to attach or remove the rims or shutters, the metal shutters of the present invention have remarkable practical effects, such as allowing even general users to replace the panels. .
