Description

[Technical Field]

[0001] The present invention relates to monuments such as gravestones, grave markers, memorial tablets, and memorial tablets, and to methods for manufacturing such monuments, and more particularly to metal monuments made of corrosion-resistant metals and methods for manufacturing such monuments. [Background technology]

[0002] Tombstones and grave markers are generally made from processed stone and placed outdoors for long periods of time, so natural stones that are resistant to weathering and highly durable, such as granite, andesite, diorite, and gabbro, are the stones of choice. There are also some elaborately designed glass monuments made from crystal glass, but they are fragile and require careful consideration for durability.

[0003] On the other hand, there have been proposals for using metal for the monument. Using metal for the monument makes it easier to process and repair than stone or glass, and if a corrosion-resistant metal is selected, it will be durable enough outdoors. It can also be recycled by remelting.

[0004] For example, Patent Document 1 discloses a metal tomb with a hollow section assembled from stainless steel plates. Providing a hollow section reduces construction costs, makes maintenance easier, and prevents collapse in earthquakes.

[0005] There is also a proposal to use metal materials for things like memorial tablets, which are made of wood.

[0006] Patent Document 2 discloses an aluminum alloy memorial tablet that is hollow inside and decorated with a baking finish or electroplating method as a surface treatment. By manufacturing the memorial tablet using a nested die-casting method that leaves the inside hollow, it is possible to form detailed patterns while combining features such as luxury and high-class feel, and because it is easy to mass-produce, it can be supplied at low cost and is easy to handle.

[0008] In recent years, many corrosion-resistant alloys other than stainless steel have been proposed, but the melting points of most of these alloys are generally high, making casting too expensive. Furthermore, complex post-processing steps such as cutting and polishing are required to create a beautiful appearance after casting, further increasing costs. Therefore, there is a demand for a metal monument made of a corrosion-resistant metal that is both aesthetically pleasing and inexpensive.

[0009] The present invention has been made in view of the above circumstances, and its object is to provide a metal monument made of a corrosion-resistant metal and a method for manufacturing the same. [Means for solving the problem]

[0010] The present invention is characterized by including a hollow shell structure made of a laminated structure of corrosion-resistant metal.

[0011] These features make it possible to make a monument that is aesthetically pleasing whether it is used indoors or outdoors, as it is made of corrosion-resistant metal, and the hollow laminated structure increases its strength, reducing material and manufacturing costs.

[0012] The above invention may be characterized in that it has a main body and a base that supports the main body, and the main body and the base are a continuous laminated structure. Furthermore, the main body and / or the base may be provided with markings and / or decorations consisting of letters or symbols. This feature further reduces manufacturing costs.

[0013] In the above invention, the corrosion-resistant metal may be made of an alloy based on nickel, titanium, or tin, which provides a beautiful monument and reduces manufacturing costs.

[0014] The above invention may be characterized as a grave marker, monument, or memorial tablet. This feature allows it to be used as a substitute for a monument generally made of stone, glass, or wood without losing its intended value.

[0015] In addition, the manufacturing method according to the present invention is a method for manufacturing a metal monument including a hollow shell structure made of a laminated structure of corrosion-resistant metal, characterized in that powder or wire of the corrosion-resistant metal is melted to form unit layers of the laminated structure.

[0016] These features make it possible to make a monument that is aesthetically pleasing whether it is used indoors or outdoors, as it is made of corrosion-resistant metal, and the hollow laminated structure increases its strength, reducing material and manufacturing costs.

[0017] The above invention may be characterized in that it has a main body and a base that supports the main body, and the main body and the base are provided as a continuous layered structure. The main body and / or the base may be provided with a display consisting of letters or symbols and / or decoration as a continuous layered structure. This feature further reduces manufacturing costs.

[0018] In the above invention, the corrosion-resistant metal may be made of nickel, titanium, or a tin-based alloy, which can be used as a substitute for stone, glass, or wood without impairing the intended value of the monument. [Brief explanation of the drawings]

[Figure 2] (a) is an oblique view of the metal monument during its manufacturing process, and (b) is an enlarged view of a portion thereof. [Figure 3] FIG. 10 is a front view of another embodiment of the metal monument. [Figure 4] FIG. 10 is a front view of yet another embodiment of the metal monument. DETAILED DESCRIPTION OF THE INVENTION

[0020] A metal monument and a method for manufacturing the same according to an embodiment of the present invention will be described with reference to FIGS.

[0021] As shown in FIG. 1, metal monument 10 is a grave marker that includes main body 11, which is a hollow shell structure (see FIG. 2) made of a laminated structure of corrosion-resistant metal. In other words, metal monument 10 is used in the same way as a gravestone, and includes main body 11, which is a grave marker, and base 12 that supports main body 11. Main body 11 and base 12 may be constructed separately, but it is also preferable to manufacture them as a single, integrated structure. Since metal monument 10 is a grave marker, in addition to main body 11 and base 12, it may also include other surrounding structures such as an outer fence or tower (not shown).

[0022] Examples of corrosion-resistant metals include stainless steel and alloys based on nickel, titanium, or tin. Stainless steel with a relatively high corrosion resistance and a chromium content of 11% by mass or more is preferred. Aluminum alloys may also be used in inland areas with low salt content or indoors.

[0023] In this way, the metal monument 10 is made of a corrosion-resistant metal and can withstand corrosion whether used indoors or outdoors, and can be made to have an excellent aesthetic appearance as a grave marker.

[0024] The main body 11 is provided with indicia 13 consisting of letters and symbols, and decorations 14 with bamboo leaf-like patterns to create a gravestone. The indicia 13 and decorations 14 may also be provided on the base 12. By providing indicia 13 on the main body 11, the metal monument 10 can acquire objective value as a grave marker. The objective value of a grave marker is to maintain its structure so that it can be used for funerals, for example, by maintaining the inscription and decorations of the gravestone.

[0025] Referring also to FIG. 2, such a metal monument 10 can be manufactured by melting powder or wire of a corrosion-resistant metal, forming unit layers 15 of a laminated structure, and stacking these layers. In other words, this is a manufacturing method using a 3D printer. For example, by forming the unit layers 15 into a frame shape when viewed from above and stacking them, the main body 11 can be made into a hollow shell structure. The detailed manufacturing method can be selected appropriately from a variety of known methods for manufacturing laminated structures using corrosion-resistant metals.

[0026] This manufacturing method of laminating unit layers 15 is advantageous because it allows for relatively free design of the shape of the metal monument 10. For example, by laminating the unit layers 15 with recesses 16 formed in advance on the front side of the layers in a shape corresponding to the indicia 13 or decoration 14, the indicia 13 or decoration 14 can be displayed on the front side. Convex portions can also be used instead of the recesses 16. In this way, the indicia 13, decoration 14, and other shapes can be added during the lamination process.

[0027] It should be noted that such a manufacturing method using lamination of unit layers 15 also makes it easy to manufacture the base 12 and main body 11 as an integrated structure. Furthermore, even when an integrated structure is used, the lamination manufacturing method makes it easy to manufacture the base 12 as either a hollow or solid structure. If the base 12 is hollow, it is possible to reduce the overall material cost and weight. On the other hand, if the base 12 is solid, it is possible to lower the center of gravity when placed on the table, preventing collapse due to an earthquake or the like.

[0028] By including a hollow shell structure as the main body 11, the metal monument 10 can increase its strength and reduce material and manufacturing costs. For example, by making it hollow, the weight relative to the apparent volume can be reduced. In other words, by setting the thickness of the shell structure, the apparent density can be reduced while maintaining high mechanical strength. The apparent density is, for example, 5 g / cm 3 Furthermore, the apparent density can be, for example, 2.6 to 2.8 g / cm, which is equivalent to that of stone. 3 It is quite possible to achieve this level.

[0029] By manufacturing the metal monument 10 as a laminated structure, it is possible to achieve a high degree of freedom in shape and a monument with excellent design relatively easily. Furthermore, the color of the metal monument 10 can be changed by surface treatments such as anodizing and nitriding, resulting in an excellent appearance. Because the metal monument 10 is made of a metal material, the surface roughness can be changed relatively freely by polishing or sandblasting, which also results in an excellent appearance. The outer surface of the metal monument 10 may be given a metallic texture using a metallic surface, or other textures may be given by painting.

[0030] The metal monument 10 can also be manufactured as a gravestone without a base and placed or fixed to another base. The surrounding structures other than the gravestone and base (main body 11 and base 12) can also be hollow shell structures made of laminated corrosion-resistant metals. By using a similar structure for the surrounding structures, a sense of unity as a gravestone can be easily achieved.

[0031] Such metal monuments can be used for various monuments other than grave markers, such as roughly rectangular parallelepipeds, roughly spherical structures, or other thick structures with surfaces that can bear inscriptions or similar letters or symbols.

[0032] For example, as shown in FIG. 3, a metal monument 20 can be used as an ihai (memorial tablet). In this case, too, it includes a main body 21, which is a hollow shell structure made of a laminated structure of corrosion-resistant metal, and a base 22. The main body 21 is provided with a marking 23, such as a posthumous Buddhist name, and the base 22 is provided with decoration 24. The decoration 24 is formed, for example, by holes that penetrate perpendicularly to the surface of the paper, like openwork. Even with this structure, the main body 21 and base 22 can be easily manufactured as a single unit by using a manufacturing method that involves laminating unit layers. When used as an ihai (memorial tablet), the marking 23 on the outer surface may be provided by a recess, as described above, or by painting the outer surface.

[0033] A metal monument 30 can also be used as a memorial, as shown in FIG. 4. In this case, as with the above, it includes a main body 21, which is a hollow shell structure made of a laminated structure of corrosion-resistant metal, and a base 22. Here, both the main body 31 and the base 32 have shapes that mimic natural stone, with an approximately spherical and a disk-like appearance, respectively. Even if this shape is unstable when the main body 31 is stacked on the base 32, a highly stable structure can be achieved by manufacturing the main body 31 and the base 32 as a single unit, as with the above.

[0034] As described above, the metal monuments described above can be used for grave markers, memorials, memorial tablets, etc. Furthermore, because metal monuments made of corrosion-resistant metals have excellent corrosion resistance, they can be used to replace stone, glass, or wood grave markers, monuments, memorial tablets, and other monuments without compromising their intended value as monuments. On the other hand, because metal monuments are made of metal materials, they can be recycled and still have a certain degree of value as materials.

[0035] While the representative embodiments of the present invention and modifications based thereon have been described above, the present invention is not necessarily limited to these, and a person skilled in the art will be able to find various alternative embodiments and modifications without departing from the spirit of the present invention or the scope of the appended claims.
