Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a central pillar of a shutter installed in an opening.

[Prior Art] Conventionally, when installing a shutter in a wide opening, there is a limit to the strength of a series of shutter curtains, so a central pillar is inserted between the adjacent ends of each shutter curtain. It is known to divide the opening and install two or more shutters in parallel.

The above-mentioned center column is generally made by assembling the main body member, which has a guide section formed into an H-shaped cross section using a roll or bender, and other accessory members by welding or other means. processing, undercoating,
After a series of painting processes including finishing and drying, a sound deadening material such as mohair is finally inserted into the guide section of the shutter curtain to complete the center column.

On the other hand, a comparison was made in which the main body member is made of an aluminum extrusion molded product that does not rust and has a good appearance, and the central pillar is constructed by inserting the sound-deadening material such as mohair into the guide part, and the painting process is omitted. The high quality middle pillars are also known.

However, in the case of molded products made of steel sheets, in addition to the main body molding process, separate equipment is required for the painting process as mentioned above, which may lead to a decrease in productivity, and the paint used for painting must be installed separately. Attention must also be paid to the influence of the atmosphere on the environment, and painted finished products are prone to scratches on the painted surface depending on handling, which can lead to rust.
In addition, when using aluminum extrusion molded products, the material cost is high, and the shapes and colors are limited. It had the disadvantage that it could not be realized.

[Problem to be solved by the invention] The present invention was devised in view of the above-mentioned actual situation in order to eliminate the drawbacks of the conventional method, and its purpose is to use a molded product made of steel plate. However, the aim is to provide the core of a shutter that eliminates the need for a painting process, improves productivity, allows for free selection of designs and colors, and increases product value.

[Means for solving the problem] In order to solve the problem, the technical means adopted by the present invention is to form a guide part with an H-shaped cross section so as to insert the adjacent side edges of the shutter curtains arranged in parallel. The central pillar is made of metal and is characterized by being covered with a plastic decorative board from the front and back surfaces along the inner wall of the guide part over substantially the entire length of the central pillar main body.

[Function of the invention] Therefore, according to the invention, it is possible to use a molded steel plate as a center column with a high degree of selectivity in design and color, and also to use a plastic decorative board as the main body of the center column. A central column with excellent rust prevention properties can be easily completed by simply coating it on the surface.

[Example] The configuration of the present invention will be described in detail with reference to an example shown in the drawings.

The figure is an exploded perspective view of the central pillar of the shutter according to the present invention.The central pillar main body 1 is made by bending a thin metal plate using a forming machine such as a roll or bender, and forms a guide part 3 for the shutter curtain 2 on one side. Square pipe-shaped members 4, 4 are welded with the guide portions 3, 3 facing away from each other to form a column having an H-shaped cross section.

On the other hand, the plastic decorative board 5 is made of heat-softened plastic sheets of various colors, which may be softened by heating and coated over approximately the entire length of the center column body 1, and then rapidly cooled and hardened. It is molded in advance according to the shape of the middle pillar body 1, and then the middle pillar main body 1 is formed.
By inserting and covering substantially the entire length of the center column 6, the assembly of the center column 6 can be easily completed.

Furthermore, the plastic decorative board 5 is coated up to the inner walls of the guide parts 3, 3, and has the effect of absorbing the noise generated when guiding the shutter curtain 2 up and down, similar to conventional sound deadening materials such as mohair. Obtainable.

Note that the middle pillar 6 in the figure has a chevron-shaped protruding decorative surface 5a.
A plastic decorative board 5 is provided on the front surface of the central pillar 1 to improve the design. It is designed to be inserted into a central pillar guide part cut out and provided in the shutter delivery opening (not shown).

[Effects of the invention] In short, the present invention is a metal center column having a guide portion formed in an H-shape in cross section so as to insert the adjacent side edges of shutter curtains arranged in parallel. Since the column body is covered with a plastic decorative board from the front and back surfaces along the inner wall of the guide part over almost the entire length of the column body, it requires less equipment and space for the steel plate painting process, even though it uses an inexpensive molded product made of steel plate. By simply covering the center pillar body with a plastic decorative board, it has the same noise-absorbing effect as conventional sound-absorbing materials such as mohair, without deteriorating the environmental hygiene caused by the painting atmosphere. It is possible to easily complete a center column with excellent rust resistance, which improves productivity, and also improves design and color selectivity, increasing the commercial value of the center column. This has extremely useful practical effects.
