Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tablet. In particular, the present invention relates to a metal figure with a portrait suitable for general individuals.

[0002]

2. Description of the Related Art Originally, it is universal that a wooden tile is a wooden tile, but the biggest reason for this is the material adopted based on the Buddhist world's idea that "everyone will return to the earth". In addition, it is relatively easy to process.

[0003] Speaking of high-grade tiles that are currently representative, they are made of ebony or rosewood, and their features are "heavy, rich in rigidity, and fine-grained on the surface. Higher and more durable ”is superior to other wooden products, but on the other hand, it is currently difficult to adopt it in temples and the like because it is expensive.

[0004] In addition, ebony and rosewood products have the following problems.
Since it is very difficult to engrave a complicated pattern on a pedestal portion or the like at the time of production due to the hard material, it is not suitable for mass production and must be more expensive in terms of price.

On the other hand, in the world of Buddhism, Buddhist tools made of synthetic resin are basically not accepted because they are contrary to the idea. However, metal Buddhist tools have been used in various ways since ancient times, with the exception of plaques, because they are recognized as "minerals". Also, casting using a mold,
Produced by a so-called die casting is where are utilized widely in current various fields. This is no exception for Buddhist accessories.

Nevertheless, as far as the tiles are concerned, the metal tiles based on the die-casting method have not been developed until now, and it is a reality that only wood is used as though it is a common wisdom. is there. The main reason for this is that the “plaque” itself is an extremely peculiar product, so it is considered that the concept of “a sanctuary that is difficult to step into” was found in the metal product manufacturing industry and the like. At the same time, in the Buddhist world and the Buddhist utensil industry, there is a prejudice that metal is too heavy, and it seems that until now, metal tiles have never been seriously considered.

[0007] If it is considered that a metal tile is made into a product by processing only its surface in the same manner as a wooden tile currently used, it is natural that it is "too heavy" and it is far from practical use. It is quite natural to be done.

[0008] Further, in many cases, the tiles are generally stored in a relatively dark and poorly ventilated place in a Buddhist altar or the like for a long time, and it is extremely difficult to maintain the state of the tiles well for many years. It can be said that.

[0009] However, since conventional tiles are sticking to wood, the surface painting method has had to rely on the natural drying method. In the case of such a wooden tile, the shrinkage of the material tree gradually begins over time under bad conditions,
The degree of adhesion of the coating deteriorates and eventually peels off.
Therefore, wooden tiles are often used as plain wood without painting, in which case the surface discoloration starts in a short period of time, easily corrodes, and even if the shape itself does not collapse, it will darken over time. Written characters (Kaname, anniversary, etc.) cannot be read. On the other hand, ebony products, which are called high-grade tiles, have relatively high paint adhesion due to their fine grain, and can be said to be more durable than ordinary wood, but they are still not sufficient for poor environments. Moreover, it was not economical as described above.

[0010] In addition, the plaque and the phantom are treated as separate and independent ones, and the phantom has generally been used in which a photograph of an individual is put in a wooden frame.
The biggest reason, in modern society "appearance of living."
It is the most accurate and easy to use a photograph as a means of leaving a picture in the future.

[0011] Originally, it is desirable that the shadow be placed on the Buddhist altar together with the plaque. However, it has generally been unavoidable to lift the grave to a place different from the plaque.
Therefore, even if it is relatives, it is difficult to distinguish a plurality of tiles instantaneously, and when it is necessary to move a portrait or a tile depending on circumstances, the handling is complicated.

[0012] Heretofore, commemorative statues honoring the deceased's virtue and achievements have been produced as bronze statues and other metallic three-dimensional portraits. However, such statues are generally large, and have no connection with the meaning of the statue, which bears the reverence of the ancestors forever and gives thanks, and reminds of the statue and the portrait mutually. is not. In addition, since the portrait is made based on a mold that is usually overlaid with plaster etc. to make it look like a person, it is sufficient for relatively small portraits such as those used on tiles. It is difficult to make a resemblance to a deceased person, and it becomes expensive in terms of cost.

As described above, the above-mentioned problems cannot be overcome with respect to the tiles, since the tiles are made of wood from the past, and the tiles and shadows are different.

[0014]

SUMMARY OF THE INVENTION The present invention focuses on this problem, revises long-standing concepts from the metal product manufacturing industry, the Buddhism industry, and the Buddhist fittings industry, and replaces the conventional common sense with a new tablet. In addition to the high quality tiles and other features of luxury, such as luxury and high-quality tiles that could not be obtained with conventional wooden tiles, it is possible to form fine patterns and improve mass productivity. It is an object of the present invention to provide a new tile that can be supplied at a low price because of its superiority and that can be remembered and remembered even when the person of the tile is passed down to the last generation.

[0015]

SUMMARY OF THE INVENTION The present invention provides a metal portrait tile provided with a metal tile and a portrait portion representing an individual's shadow on the front of the tile.

[0016] Preferably, the metal tile is mainly composed of aluminum or zinc, and the portrait plate is mainly composed of copper or brass or copper and brass. The portrait part has, for example, a thickness of 1.
Three-dimensional sculpture is performed by digging a 5 mm metal plate at a depth corresponding to the density of the original image of the remains.

An outer frame portion is provided as a frame around the portrait portion so as to surround the portrait portion. To take this configuration,
More preferably, a frame formed by stamping and pressing copper or brass having a thickness of 2 to 3 mm or a material containing copper and brass as a main component is attached to the front surface of a metal tile, and the frame is The outer frame of the picture frame surrounds the portrait.

The metal tile has an upper plate and a pedestal which are individually cast, and an insertion portion is provided on the bottom surface of the upper plate, and an insertion hole corresponding to the insertion portion is provided on the upper surface of the pedestal. Are inserted into the insertion hole of the pedestal portion, so that the portrait portion is provided on the front surface of the pedestal portion.

The upper plate portion and the pedestal portion of the metal tile have a cavity inside each by a nesting die-casting method and have a thickness of 2 mm.
mm to 5 mm.

The top of the metal tile has an opening formed in the bottom surface, and the metal tile further has an independently molded connecting part fitted into the opening, and the insertion part of the connecting part protruding. Can be inserted into an insertion hole formed in the upper surface of the base of the metal tile.

Further, the inside of the pedestal portion of the metal tile has a cavity communicating with the back side, and the cavity can be filled in the cavity.
The back cover that covers the back side of the pedestal is removable.

The metal portrait tile is entirely colored by electroplating, so that the separable parts of the metal portrait tile are preferably individually colored and then assembled.

[0023]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A specific embodiment of a metal portrait tile according to the present invention will be described with reference to the drawings.

6 shows a front view (FIG. 6 (a)) and a side view (FIG. 6 (b)) of the metallic portrait tile 10. The metallic portrait tile 10 has a pedestal 30 and its pedestal. It has an upper plate portion 20 mounted and supported on the portion 30. The pedestal portion 3
At 0, a portrait portion 70 facing the front of the metallic portrait tile is provided on the front of the pedestal portion 30 so as to be surrounded by the outer frame portion 61 of the frame portion.

Hereinafter, each component will be described.

FIG. 4 (a) shows an upper plate portion 20 having an approximately vertically long shape having an opening 25 (FIG. 4 (a) on one side) communicating with the hollow interior. The name of the deceased or the like is engraved on one surface of the plate portion 20. Fig. 4B shows an opening of the upper plate portion 20, which is a pedestal portion 30 having a substantially square pillar shape deformed to spread to the bottom. An upper plate bottom blocking part 41 projecting from one side of a separately cast connecting part 40 (FIG. 4 (c)) is fitted into the part 25, and an insertion part 42 projecting from the other side is fitted to the upper surface of the pedestal part 30. The upper plate portion 20 is fitted into the insertion hole 32 provided in the portion 30D (FIG. 4 (b)). Is
Stopper 26 expanding inward as shown in FIG.
Was provided. When the fitting the connecting portion 40 to the position of the stopper 26, by just inserting portion 42 from the bottom of the upper plate portion 20 so as to protrude,
The upper plate portion 20 is stably and vertically connected to the pedestal portion 30.

As shown in FIG. 6, a frame 60 is attached to the front of the pedestal 30, and the frame 60 is further mounted.
The portrait portion 7 is surrounded by an outer frame portion 61 (see FIG. 5A).
0 (see FIG. 5 (b)), a recess 31 having a depth of about 1 to 3 mm is formed along the outer dimensions of the frame 60 as shown in FIG. 4 (b). You.

FIG. 5A shows the frame 60 and FIG.
(B) shows the portrait part 70. The frame 60 has its back surface bonded to the recess 31 of the pedestal 30 and fixed. In addition, the back surface of the portrait portion 70 is attached and fixed to the attachment portion 62 of the frame portion 60. Note that this fixing may be performed by an adhesive or a double-sided tape, or may be configured to be snapped.

As shown in FIG. 4 (d), the back surface of the pedestal portion 30 employs a method of closing a cavity formed therein by screwing a separately molded 2 mm thick plate-shaped back cover 50 as shown in FIG. are doing. Therefore, the back surface of the base portion 30, a stopper 35 having a step which is provided from the back inside of the base portion 30 as shown in FIG. 2 to the position entire depth of 2mm forward
In addition, taps 36 for fixing the back cover 50 with screws at four corners of the stopper 35 are cut. Also, the back cover 50
Is provided with a screw hole 51 through which a screw can be inserted so as to correspond to the tap 36 of the pedestal portion 30. The thickness of the back cover 50 is determined so that the back cover 50 becomes flat when the pedestal portion 30 is closed from the back surface. The pedestal 3
The back side surface of No. 0 employs a method in which the back cover 50 can be attached and detached by screwing or the like, and the back cover 50 is opened and closed so that the back cover 50 can be boned into the pedestal portion 30.

Next, the casting of each component of the tile and its characteristics will be described.

1. Mold and insert of the upper plate portion of the memorial tablets Figure 1 shows a mold 1 in the mechanism of the upper plate portion 20 of the memorial tablets. The mold is formed from two square steel materials prepared respectively as the front side split mold 2 and the back side split mold 3 of the upper plate portion. The square steel materials for the front and back sides are the first
As shown in FIG. 2A, one side is set to the bottom side of the upper plate portion 20. Then, each square steel material is carved to a depth of about 6 mm while being adjusted to the outer shape of the upper plate portion 20. At that time, the front side split mold 2 is carved and, if necessary, a back pattern or the like is carved. I do. The mold matrix 1 is obtained by combining the split molds 2 and 3 for the front side and the back side formed by engraving.

The engraved surfaces of the two split molds 2 and 3 are
Matrix 1 fixed face-to-face as shown in Figure (b)
The molten aluminum is poured into the
An upper plate-shaped casting having a thickness of 2 mm can be obtained.

On the other hand, according to this manufacturing method, a cavity is not formed in the casting, but becomes heavier. Therefore, a cavity is formed in the casting by incorporating and casting an “insert” inside the matrix.

The nest 5 is put in the carved inside of the split molds 2 and 3 for the front and back sides. The nest 5 has a width and a thickness smaller by 4 mm and a length by 2 mm than the cavity inside the matrix 1, respectively.
This is obtained by manufacturing a mold having the same shape as the upper plate portion 20. However, as shown by "A" in FIG. 1 (a), the insert 5 is made slightly narrower toward the tip (upper portion), but this becomes a draft angle during casting.

2. Casting of the upper plate portion As shown in FIG. 1 (b), the center of the hole-shaped portion 6 formed on the bottom surface of the upper plate portion 20 of the matrix 1 set in the casting machine is nested. When the mold 5 is set to be inserted, a clearance of 2 mm is formed between the inner surface forming the cavity of the matrix 1 and the outer surface of the insert 5.

The molten aluminum was poured by applying pressure to the gap, and at the time of solidification, the casting was taken out with the split molds 2 and 3 opened to the left and right while pulling out the insert 5. An upper plate portion 20 having a thickness of about 2 mm and a cavity corresponding to a minute is obtained.

This casting method is basically the same as the casting method of the pedestal portion 30.

3. Basically, as in the case of the upper plate portion 20, this is a mold in which nests are incorporated in a split mold, but the structure is more complicated.

As shown in FIG. 4 (b), the pedestal portion 30 has a complicated uneven pattern on the entire surface except for the bottom surface. With a simple split mold, the casting is removed from the mold after casting. It is impossible.

In order to make it possible to remove the casting, split dies for the left side portion 30A, front portion 30B, right side portion 30C, and upper surface portion 30D of the pedestal portion are separately manufactured and combined, and four split dies are formed after casting. Was opened in four directions, and a casting (pedestal portion) was taken out to form a 40-divided matrix.

As with the nesting of the upper plate portion, a mold having the same shape as the pedestal portion with a draft angle and reduced by 2 to 5 mm is manufactured and used as the nesting.

The reason why there is a difference between the reduced dimensions of 2 mm to 5 mm is that the top surface and the bottom surface of the pedestal portion 30 have no convex pattern as seen from the back side of the pedestal portion 30 in FIG. Is suppressed to a reduction of 2 mm, but with respect to the convex portion on the side surface, the convex pattern has a maximum of 3 m in this example.
This is because the m projections require a reduction of at most 5 mm.

4. Casting method of pedestal portion As with the casting method of the upper plate portion 20, a 40% mother die is set in the casting machine, and set with the nest inserted into the center from the position corresponding to the back side surface of the pedestal portion 30. Then, between the matrix and nesting,
There will be a gap of 5 mm. Pouring aluminum dissolved under pressure in this gap, when taking out the casting in the state of opening four sides of the mold while pulling the insert when solidified, the base section 3 which is hollowed in the thickness 2~5mm
0 is obtained.

5. Manufacturing method of picture frame for portrait The center of the picture frame 60 has a substantially flat portrait plate sticking portion 62 having a depth of about 1.5 mm from the periphery so that a portrait 70 having a substantially flat back can be stuck. Have. In addition, an outer frame portion 61 is formed around the portrait plate so as to surround the portrait board.

As one method of manufacturing the frame portion 60, a mold in which the pasted portion 62 of the completed portrait portion 60 is carved upside down so as to have a concave shape with a depth of about 1.5 mm is formed by a reflection method. After stamping a plate mainly composed of copper or brass with a thickness of about 3 mm, or an alloy thereof,
A method of pressing and manufacturing the outer shape can be used.

6. Method of Manufacturing Portrait Portion A portrait photograph as a basis of a portrait is converted into a monochrome image by an image processing device such as a personal computer or the like, and image data is created by dividing each pixel of the image into, for example, 256 levels according to shading. Then, using the obtained image data, the digging depth is determined according to the density, and the data is converted into data usable by the engraving machine. Using the converted data, an original plate prepared is dug by an engraving machine to produce a desired portrait section 70.

For example, when a copper or brass plate having a thickness of about 1.5 mm or an alloy plate containing these as a main component is used, the maximum depth of the digging may be 0.4 mm, depending on the density of the photograph used. By dividing the shade portion into 256 levels and setting the depth gradually as the density increases, it is possible to represent the outline of the deceased's remains.

The photograph of the photograph is read by a personal computer, converted into a monochrome image, and the image data is converted into data for an engraving machine by changing the depth of the sculpture moat according to the degree of shading. A series of processing to dig in can be automatically performed. Further, in this example, the photograph is equally divided according to the shading, and further, the difference in depth is equally divided. The depth may change in a curved manner.

The engraved portrait plate is stamped out in accordance with the required dimensions, and the portrait portion 7 shown in FIG.
0 is completed.

7. The surface treatment of the tiles The baking coating method or the electroplating method was adopted for coloring the tiles to take advantage of the characteristics of the metal material.

The baking coating method is a method of continuing baking, for example, at 180 ° C. for 30 minutes in a predetermined environment in a baking oven after coating, and has an effect of further increasing the “adhesion and hardness” of the coated paint. .

The electroplating method uses various metal layers such as copper plating, nickel plating, and 24
The layers are sequentially applied by gold plating. In the present embodiment, a baking clear coating is finally applied to this electroplating method in order to further increase the corrosion resistance. As a result, it was possible to maintain an excellent touch resistance while exhibiting a gorgeous appearance.

The above-mentioned plating is applied to each component in advance, and thereafter, each component is assembled, so that a good plating process can be flexibly adapted according to the plating quality of the component and the metal used. It becomes possible to plan.

8. Problems in casting and their solutions (A) The die casting method is a casting method in which a metal melted at a high temperature is poured into a mold under pressure. There is. Therefore, when casting a thin plate, since the metal is poured into a narrow place, solidification starts in a situation where it is difficult to flow uniformly over the entire surface, and as a result, pinholes appear on the ground of the casting after casting, and voids enter. There is a problem that the phenomenon easily occurs.

The upper plate portion 20 of the tablet according to the present invention also has a very thin condition of 2 mm in thickness and a long and thin cylindrical shape, so that the casting condition is extremely poor, and pinholes and the like are easily formed.

[0056] As the present invention is the solution, degassing the center position of the normal Upon casting provided a is sprue 1 places the (pouring inlet) symmetrically positioned two places of the bottom portion and the opposite side (distal portion) By making the holes, the molten metal can be immediately and uniformly poured during casting, and the upper plate portion having a smooth ground surface was successfully cast.

(B) In the case where the upper plate is connected to the pedestal on a plane, the upper plate must be perpendicular to the pedestal. In particular, when commercializing, it must be made with emphasis on all aspects such as “moderate weight, practicality, price, appearance (luxury feeling)”, etc. However, on the other hand, the following obstacles will arise when the upper plate is to be set up vertically.

(1) As shown in FIG. 1 (a), the upper plate portion has a draft toward the tip end for the purpose of facilitating removal of the cast insert 5 during casting. since the figures are given, the thickness of the cast upper plate portion 20 becomes thicker as the toward the tip portion in inverse proportion to the nest, as a result, FIG. 1 (b)
As shown by “B”, the tip portion is thicker and heavier than the bottom portion. Therefore, when the upper plate is erected, the center of gravity is high and the stability is lacking.

(2) As shown in FIG.
As shown by the front mold 2 in (b), a rounded pattern 23 (see FIG. 4 (a)) with a corner cut along the edge of the tile is inserted. When inserted, the shape of the bottom surface of the upper plate portion that is in contact with the upper surface of the pedestal portion is such that both corners 24 of the back portion are right angles, whereas both corners 23 of the front portion are rounded. As a result, the surface area of the front side portion in contact with the pedestal portion is smaller than that of the back side portion. For this reason, the upper plate portion 20 cannot be evenly supported by the pedestal portion 30, and the upper plate portion tends to fall forward.

(3) In the case where the upper plate portion 20 and the pedestal portion 30 are connected in a plug-in type, the size of the insertion hole 32 of the pedestal portion 30 is not large enough to secure stability. Is generally not easily pulled out when inserted. The present invention takes into account the “practicality” of convenience in temples, individuals, etc.
When the size of 2 is made larger by 1 mm each in the vertical and horizontal directions than the outer dimension of the insertion portion 42 of the upper plate, the upper plate is not fixed to the pedestal, and lacks stability. Results.

(4) Since the thickness of the upper surface of the pedestal portion is 2 mm by the telescopic casting, the thickness of the insertion hole is also substantially the same, and the connecting portion for connecting the upper plate portion 20 and the pedestal portion 30 is formed. When 40 (see FIG. 4 (c)) is inserted into the insertion hole 32, a part of the insertion portion having a length of 10 mm of the connecting portion 40 protrudes into the inside of the pedestal portion of 2 mm. In this state, since the tangent plane of the upper plate portion is too small, the role of the support for keeping the upper plate portion vertical is little.

[0062] The above (1) to (4) structural problems overlap phase, when inserting the upper portion to the base portion, the upper plate portion 20 are not stand perpendicular to the base portion 30, slightly You will be in a state of falling down to you.

According to the present invention, as a solution to the above, first, regarding the above (4), which can be structurally improved, as a method of supporting the entire surface of the insertion portion 42 of the upper plate portion 20, the insertion hole 32 of the pedestal portion is used.
The dimensions of the depth portion 33 is thicker in the back so as to surround the,
By setting the length to 10 mm in accordance with the protrusion size of the insertion portion 42, the insertion portion 42 inserted into the cavity (see the broken line portion D in FIG. 3) surrounded by the depth portion 33 is supported from the surroundings, and the weight is increased. Instead of making the entire upper surface 10 mm thick in order to minimize the influence of the target, only the area around the insertion hole 32 was improved to this thickness as shown in FIG.

Further, (1) to (3) are to be solved by the following method.

[0065] In the structural problem of (3), when inserting the insertion portion 42 to the insertion hole 32 of the base portion, between the insertion hole 32 and the insertion portion 42 without providing the "play",
If the structure is such that the insertion portion is tightly inserted, the upper plate portion 2
0 is fixed to the pedestal portion 30, and the upper plate portion 20 can maintain stability on the pedestal portion 30 and can be made harder to fall down.

In this embodiment, however, the size of the insertion hole 32 is made larger and 1 mm larger than the size of the insertion portion 42, so that the upper plate portion 20 falls forward in accordance with the play of 1 mm. It becomes a tendency. Therefore, the upper plate 20
The auxiliary pillow 34 is integrally provided on the upper surface 30D of the pedestal portion 30, as shown in FIGS. The position and the shape of the auxiliary pillow 34 are such that when the upper plate portion 20 is connected to the pedestal portion 30 by the connecting portion 40, one surface of the auxiliary pillow 34 is aligned with the surface of the upper plate front surface 21. The width is set to 0.5 mm from the viewpoint that the smaller the contact area with the upper plate is, the more effective it is provided in accordance with the lateral width of the front side flat portion 21. As a result, when the upper plate portion 20 was connected to the pedestal portion 30, the upper plate portion 20 was stood upright and almost constantly perpendicular to the pedestal portion 30 to be stable.

In the above example, aluminum was used as the material of the upper plate and the pedestal of the tablet. However, in order to give a more luxurious feeling and to have a moderate feeling of weight that would not be inconvenient to handle as a general-purpose tablet, aluminum was used. Instead of the material, a zinc material or other metal that can be molded may be used depending on the application. In addition, by using zinc material,
Electroplating such as pure gold plating can be performed more easily.

[0068]

The biggest difference between the present invention and the present invention is that
Above all, the material of the present invention is the first made of metal, whereas the conventional material is all made of wood. In other words, the present invention focuses on the existing established concept, and provides a new economical and highly durable tile that could not be obtained by conventional concepts. Have

Further, according to the present invention, it is possible to easily compare a tablet with a person by combining a tablet and a shadow, which are conventionally handled individually, and to decorate a shadow in a place unavoidably distant from the tablet. The present invention is to provide a new tablet which can identify individuals instantaneously and eliminates the inconvenience of handling such as restrictions on places such as Buddhist altars and inconvenience in handling.

In addition, the tile according to the present invention is provided with a back cover so as to be openable and closable so that the tile can be boned, and the portrait, the bone and the bone are integrated. It can directly contribute to the original role of honor and praise directly and eternally, and also contributes to the enlightenment of "the Buddhist way of teaching the ancestors'hearts".

Further, since the upper plate and the pedestal can be separated from each other and the upper plate can be easily removed from the pedestal, handling during cleaning and movement is facilitated.

Further, according to the present invention, although it is lighter, it is made of metal which is heavier than wood, so that it does not move even if it is slightly shaken, has stability, and can keep the same posture in structure. .

Further, even when stored for a long time in a place that is relatively dim and poor in air permeability, it is possible to eliminate the inconvenience that corrosion and discoloration hardly occur and the written command or anniversary cannot be read. By applying such a method, it became possible to exhibit excellent abrasion while maintaining excellent touch resistance.

In addition, according to the present invention, a stereoscopic portrait can be obtained relatively easily as a photograph by digging the depth so as to be different depending on the density of the photograph to be portrait.
For example, even in a household tile or the like where a shadow must be provided in a rectangle of about 45 mm × 55 mm, a shadow that can easily recognize the deceased is enshrined.
