JPH0677920U - Perforated metal and multi-layer board using the same - Google Patents

Abstract

(57) [Summary] [Structure] A large number of perforations 1 are formed over substantially the entire area of the metal plate B, and a predetermined pattern C is formed by the large number of perforations 1 having different diameters. [Effect] Since a watermark pattern having a unique texture is exhibited, it is excellent in decorativeness. Moreover, the pattern C can be easily formed only by forming the perforations 2 in the metal plate B.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a perforated metal and a multilayer board using the same.

[0002]

[Problems to be solved by conventional techniques and devices]

 Conventionally, a perforated metal having a large number of perforations formed over the entire area of a metal plate has been used as a building material such as a partition plate, a ventilation protection cover, a protective fence, or an exterior cover of various devices. . However, since the conventional perforated metal has a monotonous pattern in which perforations having the same diameter are arranged in a checkerboard pattern or a zigzag pattern, there is a problem that the decorative property is poor and the use thereof is limited.

On the other hand, for example, a front basket and a skirt cover (dress guard) as bicycle parts are formed by bending or braiding a metal wire. In order to display the brand, characters, etc., it is necessary to attach a metal plate on which these are printed by screwing, etc., which is troublesome, lacks a sense of unity, and is poor in decorativeness. . The present invention has been made in view of the above problems, and it is possible to easily form various patterns such as letters, figures, symbols, etc., and perforated metal excellent in decorativeness and a multilayer board using the same. The purpose is to provide.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the perforated metal according to claim 1 is characterized in that a large number of perforations are formed over substantially the entire area of a metal plate, and a predetermined pattern is formed by the large number of perforations having a diameter different from the perforations. It is what A multilayer plate according to a second aspect is characterized in that a transparent plate is laminated on at least one surface of the perforated metal.

[0005]

[Action]

 According to the perforated metal according to the above-mentioned claim 1, the perforations formed over almost the entire area of the metal plate allow light to be transmitted almost entirely, and the apertures of the perforations and the pattern-formed perforations. The difference in the amount of transmitted light or the amount of reflected light due to the difference can cause light and dark between the pattern portion and the background thereof, and thus a watermark pattern having a unique texture is exhibited. Moreover, the pattern can be easily formed only by perforating the metal plate.

According to the multi-layer plate of the second aspect, the perforated metal can be reinforced by the transparent plate without damaging the pattern peculiar to the perforated metal.

【Example】

 Embodiments will be described below in detail with reference to the accompanying drawings. FIG. 1 is a plan view showing an embodiment of the perforated metal A of the present invention. The perforation metal A has a large number of basic perforations 1 formed in almost the entire area of a thin metal plate B such as an aluminum plate, a stainless plate, or a copper plate, and has a larger diameter than the basic perforations 1. A pattern C such as a person is formed by the perforations 2 of FIG.

The respective perforations 1 and 2 are formed by an NC-controlled perforation press, and while the relative positions of the press and the metal plate B are shifted vertically and horizontally, the mutual perforations of the basic perforations 1 are formed. The pattern C is formed by forming a hole 2 for forming a pattern, instead of the space or the hole 1. According to the perforated metal A having the above-described structure, the basic perforation 1 allows light to pass through almost the entire metal plate B, and the aperture difference between the perforation 1 and the perforation 2 for forming a pattern. Since the amount of transmitted light or the amount of reflected light differs depending on the type, for example, when the back of the perforated metal A is dark, the portion where the perforation 2 for pattern formation is formed is the basic perforation 1 as shown in FIG. It becomes darker than the formed part (background part), and the pattern C stands out. On the contrary, when the back is bright, the portion where the perforation 2 for pattern formation is formed becomes brighter than the portion where the perforation 1 as the base is formed, and the pattern C stands out.

As described above, the perforated metal A can generate light and dark between the pattern C and the background portion thereof in a state where light transmission is allowed over almost the entire metal plate B. Thus, a watermark pattern having a unique texture is exhibited. Moreover, since the pattern C can be formed only by the holes, the pattern C can be easily formed.

The perforated metal A can be used as a louver for partitioning, a partition plate, a decorative plate or the like as it is or by cutting it into an appropriate size. Also, by bending or welding, it is possible to form a front car D (see FIG. 2), a chain case E (see FIG. 3) or a skirt cover for a motorcycle such as a bicycle or a minibike. .

Further, as shown in FIG. 4, the perforated metal A may be laminated in a state of being sandwiched between two transparent plates 3 and 4 made of glass or acrylic resin to form a multi-layer plate F. In this case, since the perforated metal A can be reinforced by the transparent plates 4 and 5, and the perforated metal A provides a watermark pattern having a unique texture, the safety glass, the lighting plate, the door, the partition It can be suitably used as a decorative plate, a blind plate for a balcony, a top plate for a desk, and the like. A semi-transparent plate such as frosted glass may be used for either one of the transparent plates 4 and 5. The transparent plate may be laminated on at least one surface of the perforated metal A.

The perforated metal and the multi-layer plate of the present invention are not limited to the above-mentioned embodiment, and for example, the pattern C is formed by the perforation 2 having a smaller diameter than the basic perforation 1. Various design changes can be made, such as formation by combining at least two types of perforations having different diameters.

[0013]

As described above, according to the perforated metal according to claim 1, since it has a transparent pattern having a unique texture, it is excellent in decorativeness and can be used for various purposes. In addition, since it is only necessary to form the perforations in the metal plate, there is a practicable effect peculiar to easily forming the pattern.

Further, according to the multi-layer plate according to the second aspect, the transparent plate can reinforce the perforated metal without damaging the pattern peculiar to the perforated metal, so that strength and decorativeness are required. It can be suitably used as various boards.
