[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mosaic ornament formed by arranging decorative members such as ceramics and stones in a plane and connecting them together, a method for producing the same, and a mold used for the method.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there is a tile unit with a backing structure in which a plurality of tiles are arranged in a plane shape at intervals equivalent to joints, and a joint made of a synthetic resin is attached to the back side of the tiles to connect the tiles.
[0003]
[Problems to be solved by the invention]
However, since the conventional tile unit is only connected by a synthetic resin joint and the strength is low, the joint may be broken in the handling process before construction. In addition, the synthetic resin that constitutes the joint is difficult to develop because the conditions such as strength and adhesive strength are severe, and secondly, it is expensive because it uses a special synthetic resin. was there.
[0004]
[Means for Solving the Problems]
It is composed of at least three elements of a large number of decorative members having a uniform height, a wire, and an adhesive, and the decorative members are arranged in a plane shape with a gap corresponding to a joint, and in the middle of the height of the gap. Provided is a mosaic decorative body in which the wire material is stretched around a position and the gap is filled with an adhesive from the back side of the decorative member so that the decorative members are bonded together via the wire material.
[0005]
In this mosaic decorative body, since a wire is interposed between decorative members, the strength is much higher than that of a conventional synthetic resin 100% back joint, and the adhesive does not require any special strength. Commercially available adhesives can be used as they are.
[0006]
The mosaic ornament can be manufactured by a method having the following requirements (a) to (d).
(A) A mold provided with partition means for positioning the decorative member is used.
(B) The decorative member is placed face down in a place partitioned by the partition means of the mold.
(C) A wire is stretched around the gap corresponding to the joint of the decorative member.
(D) The adhesive is filled into the gap from the back side of the decorative member.
[0007]
In addition, the mold used in the manufacturing method has a main mold component which is a bottomless box-shaped frame shape or a bottomed box-shaped form as a main component, and a locking portion for locking the wire rod on the upper surface of the mold main body. What was provided is good.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. 1 is a plan view of the mosaic decorative body, FIG. 2 is a cross-sectional view taken along line XX of FIG. 1, FIG. 3 is a perspective view of a mold, FIG. 4 is a plan view showing first and second steps, and FIG. Is a plan view showing the third step, FIG. 6 is a plan view showing the fourth step, and FIGS. 7A to 7C are cross-sectional views showing the manufacturing steps.
[0009]
As shown in FIGS. 1 and 2, the mosaic decorative body 1 includes three elements, that is, a large number of decorative members 2, a wire 3, and an adhesive 4. The decorative member 2 is formed by processing a material such as stone, wood, ceramics, glass, metal, synthetic resin, paper, or the like into a dice shape, and the height is almost uniform. In addition, the meaning of aligning the height of the decorative member 2 is such that it is only necessary to align the wire 3 within a range that does not hinder the wire 3 (this will be described later). I do not care.
[0010]
As the wire 3, for example, a hemp string or asbestos string having flexibility and relatively high strength is used. The adhesive 4 is suitable for bonding the decorative member 2 and the wire 3 and preferably has elasticity after bonding. In the specific example of the mosaic decorative body 1, the decorative member 2 is a stone, the wire 3 is a hemp string, and the adhesive 4 is a silicone-modified polymer elastic adhesive. By adopting such a combination, the mosaic decorative body 1 rich in elasticity can be obtained.
[0011]
The mosaic decorative body 1 shown in FIG. 1 and FIG. 2 has a large number (36 pieces) of decorative members 2 arranged in a plane shape with a gap 5 corresponding to a joint separated, and the wire 3 is stretched vertically and horizontally in the gap 5 and decorated. The gap 5 is filled with the adhesive 4 from the back side of the member 2, and the decorative members 2 are bonded together via the wire 3. Further, a loop 6 made of the wire 3 is formed around the mosaic ornament 1, and the plurality of mosaic ornaments 1 are connected to each other by hooking the loop 6 on the ornament member 2 of another mosaic ornament 1. Or the loop 6 can be temporarily fixed by hooking on the construction surface. If the loop 6 is not necessary, it is cut off with a scissors or a knife.
[0012]
The mosaic decorative body 1 is used for, for example, an application in which it is attached to a wall surface and decorated. When the decorative member 2 is divided into so-called tiles with ceramics, a mosaic tile wall surface can be formed by attaching the mosaic decorative body 1. Further, when the decorative member 2 is made of stone, the appearance is the same as that of the mosaic tile, but when the decorative member 2 is made of wood, glass, metal, synthetic resin, or paper, a unique mosaic-like wall surface is formed. Since the hemp string which is the wire rod 3 can be seen in the gap 5 between the decorative members 2, leave it as a substitute for the joint material 2 or fill the gap 5 between the decorative members 2 with a joint material such as joint mortar. It may be. In addition, when a flexible material is used for the wire 3 of the mosaic decorative body 1 and an elastic material is used for the adhesive 4, it can be flexibly adapted to a wall surface constituted by a curved surface. .
[0013]
In addition, the mosaic decorative body 1 can be used, for example, for decorating indoor equipment items (such as lighting fixtures, daily miscellaneous goods such as vases, etc.) and outdoor equipment items (such as baskets, gates, flower beds, etc.). Thus, the present invention is not limited to the use for wall decoration.
[0014]
Next, a method for manufacturing the mosaic ornament 1 will be described. First, a mold 7 as shown in FIG. 3 is used for manufacturing the mosaic ornament 1. The mold 7 includes a main body 7a having a bottomed box-shaped frame as a main component, and is combined with partition means 7b, which is a metal elongated bar-like member. A groove-like locking portion 7c for locking the partition means 7b and the wire 3 is provided. The width W of the four sides of the mold main body 7a is set to be approximately equal to the width of the decorative member 2 or a size obtained by adding the width of the gap 5 to the width of the decorative member 2.
[0015]
As shown on the right side of FIG. 4 and FIG. 7A, the first step for manufacturing the mosaic ornament 1 is to place the mold main body 7a on a flat place and partition it into the locking portions 7c of the mold main body 7a. The means 7b is stretched vertically and horizontally so that the inside of the mold main body 7a is partitioned into a grid-like state. The size of each eye substantially matches the size of the decorative member 2.
[0016]
The next second step is the setting of the decorative member 2 to the mold 7, and the decoration is applied to individual places partitioned by the partition means 7 b of the mold 7 as shown on the left side of FIGS. 4 and 7 (b). Insert the member 2 face down. At this time, an appropriate pattern can be formed by arranging the color-coded decorative member 2 at a predetermined location. If an arrangement drawing 8 (see the two-dot chain line in FIG. 3) color-coded under the mold 7 is laid, an arbitrary pattern can be easily created.
[0017]
The next third step is the setting of the wire 3 and, as shown on the right side of FIGS. 5 and 7B, one continuous long wire 3 is started from the starting point S (locking portion 7c) of FIG. Then, it is engaged with the engaging part 7c on the opposite bank, and then it is folded back and passed through the gap 5 of the next stage, and then it is meandered horizontally, and the corner outer periphery of the mold main body 7a is wound around the change point C of the last stage. Change the direction, this time meander in the vertical direction and end at the last end point E. At this time, the partitioning means 7b of the portion where the wire 3 is stretched is pulled out and removed one by one, or just before the wire 3 is stretched, the partitioning means 7b is removed one by one, and finally all the partitioning means 7b are removed. Change to 3. In this state, the wire 3 is positioned in the middle of the height of the decorative member 2 and fixes the decorative member 2.
[0018]
The next third step is filling of the adhesive 4, and as shown on the left side of FIGS. 6 and 7 (c), the adhesive 4 is squeezed out from the nozzle 9 of the tube to fill the gap 5 between the decorative members 2. To do. The adhesive 4 may enter the gap 5 above the wire 3, but the adhesive 4 is increased so that it protrudes from the back of the decorative member 2, and the adhesive 4 covers the back of the decorative member 2. May be.
[0019]
The next fourth step is demolding from the mold 7, and the mosaic ornament 1 is pulled out from the mold 7 as shown on the right side of FIG. In this state, since the wire 3 is adhered to the decorative member 2 by the adhesive 4, the mosaic decorative body 1 can be easily demolded by pulling up the portion of the wire 3 that has become the loop 6. If the mosaic ornament 1 thus removed is turned over and the excess wire 3 is cut off, the mosaic ornament 1 shown in FIGS. Of course, the illustrated mosaic decorative body 1 is shown to be small for the sake of simplicity, and can be manufactured in any size by enlarging the mold 7.
[0020]
Since the portion of the wire 3 removed from the mold 7 forms the loop 6 as described above, the width W of the four sides of the mold 7 is set substantially equal to or slightly larger than that of the decorative member 2 as in the above embodiment. Then, the decorative member 2 of another mosaic decorative body 1 to be joined can be hooked on the loop 6 that has been formed.
[0021]
The embodiments of the present invention have been described above, but the present invention is of course not limited to the above embodiments. For example, in the embodiment, the mold main body 7a of the mold 7 is a bottomless box-shaped frame, but may be a bottomed box-shaped mold main body 7a as shown in FIG. In this case, partition means 7b is provided on the bottom plate 7d of the mold main body 7a so as to partition in a grid pattern. Therefore, the locking portion 7 c exists only for the purpose of locking the wire 3. Also, if the surface of the partitioning means 7b is coated with an easily peelable resin (for example, a fluororesin) that is difficult to adhere to the adhesive 4, the adhesive 4 is filled in the gap 5 without any trouble even if the partitioning means 7b is provided. can do. If the bottom plate 7d is made detachable, the maintenance of the partitioning means 7b is facilitated, and the arrangement drawing 8 can be set under the bottom plate 7d by forming the bottom plate 7d transparent.
[0022]
In the embodiment, the decorative member 2 is formed in a dice shape, but the shape of the decorative member 2 is arbitrary. For example, even when the planar shape of the decorative member 2 is a triangle or rhombus, it can be dealt with by devising the arrangement of the partition means 7b and the locking portion 7c. Further, if the circular decorative member 2 is inscribed in the partitioning means 7b divided into squares or rhombus, the circular decorative member 2 can be dealt with. Moreover, although the wire 3 was formed with the flexible string in embodiment, you may form with the wire made from a metal or a synthetic resin.
[0023]
【The invention's effect】
Since the mosaic decorative body of the present invention is joined by interposing a wire between the decorative members, the strength is much higher than that of a conventional synthetic resin 100% back joint, and the adhesive is also special. Since strength is not required, there is an advantage that a commercially available adhesive can be used as it is.
[0024]
Further, according to the manufacturing method of claim 2, the mosaic decorative body of claim 1 can be mass-produced, and the manufacturing method of claim 2 can be easily implemented by using the formwork of claim 3. .
