Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall storage body forming a storage space in a wall of a house or the like, and more particularly to a wall storage body having a woody appearance.

[0002]

2. Description of the Related Art In a house, a large number of furniture such as chests of drawers, bookshelves, and storage shelves are placed and used in each room. By the way, in recent years, in order to meet the demand to make the living space as wide as possible in a limited space, when constructing a house, a closet for storing clothes etc. is provided in advance in the living room, etc. It is designed so that you can simply put the furniture in your room.

Conventionally, for example, there is a wall storage body that is embedded in a wall to form such a storage space. As this wall storage body, one that is built in a recess of a wall formed in advance, for example, a bookshelf or a storage rack on which various small items are placed is known. Such a wall storage body is made of natural wood, resin, metal or the like, and is appropriately selected and used according to the interior of the living room in which it is installed. That is, a wall storage body made of natural wood is used in a Japanese-style room, and a wall storage body made of resin or metal printed or painted on the surface is used in a Western-style room.

[0004]

However, for example, a wall storage body made of natural wood is higher in price than the raw material itself such as resin, and moreover, it requires much manual processing, so that it is more difficult than the resinous one. However, it has a drawback in that it is expensive and inferior in terms of dimensional accuracy and the like to those made of resin. On the other hand, resinous materials are widely used because they are low in manufacturing cost, but they are inferior in quality to those made of natural wood, and have the drawback of being tired when used for many years. In addition, for example, there is one that prints a wood-like pattern such as a wood grain pattern on this resinous thing to make it look like a natural tree and bring out a high-class feeling, but if it is just printed, the appearance is very close to a real tree etc. However, there is a drawback that the cheapness is rather noticeable.

The present invention has been made in view of the above circumstances, and an object of the present invention is to have a woody appearance comparable to that of natural wood, and to be obtained by a molding method similar to that of resin, and therefore to have a size. It is an object of the present invention to provide a wall container with high accuracy and low manufacturing cost.

The means. In the wall storage body according to claim 2, the connecting member is a two-piece structure that sandwiches adjacent side edges of the plate body between adjacent plate bodies of the connecting plate, the top plate, the bottom plate, and both side plates. It is a means for solving the above-mentioned problems that it is composed of a holding rod having a holding groove. In the wall storage body according to claim 3, the top plate, the bottom plate, and the both side plates are formed by mixing and pelletizing the finely divided cellulose-based particles having a surface treated with a white inorganic pigment and a resin. Wood pellets, which are made by mixing finely divided cellulose-based powder particles, which have been ground and carried white inorganic pigment on the surface, resin and colored pigments, into pellets, and whose melting temperature is higher than the dough material pellets. The forming material pellets are mixed, and the pellet mixture is formed by extrusion molding, which is the means for solving the above problems.

[0007]

According to the first aspect of the present invention, the cellulosic fine particles carrying the white inorganic pigment, which is a material for forming the top plate, the bottom plate and the both side plates, are ground. For example, unlike conventional fibrous wood that is directly pulverized into fine powder, the surface has few cilia and becomes granular, so water (including moisture) and solvent are absorbed like conventional fibrous wood powder. However, the expansion and contraction due to the release thereof is extremely small, and therefore, the respective plates formed by containing it have extremely excellent dimensional stability. In addition, by using cellulose fine powder particles, which have been subjected to a grinding treatment and carrying a white inorganic pigment on the surface, as an aggregate, the adsorption / suction of resin by the fine powder particles is extremely reduced and molding distortion hardly occurs. . Further, since the connecting plates are fitted into the hollow portions of the adjacent mounting frames to connect the mounting frames, the assembling thereof is facilitated, and therefore the frame body is easily assembled into the wall. Become.

According to the second aspect of the present invention, in addition to the connecting plate, the connecting member has a holding rod having two holding grooves for holding the side edges of the adjacent plate bodies. Therefore, the top plate, the bottom plate, and the side plates are easily connected by the connecting member, and the connection between the respective plates is strong.

According to the wall storage body of the third aspect, the top plate,
The bottom plate and both side plates are obtained by extrusion-molding or injection-molding a pellet mixture of dough material pellets and wood-like forming material pellets having a higher melting temperature. Therefore, when each plate is molded, the wood-like forming material pellets take a longer time to melt than dough material pellets.Therefore, by using this and setting the molding conditions in advance, the wood-like forming material pellets The colored pigment does not flow regularly or uniformly into the molten material during molding, and flows irregularly to form a streak-like colored portion. And
Since the striped colored portions have a wood grain pattern very close to the natural wood grain, each plate has a surface very close to that of the natural wood grain. Moreover, since the cellulosic fine powder particles in each pellet carry a white inorganic pigment on the surface thereof, in the obtained molded product, the fine powder particles come closer to the surface side than the colored pigment, thereby making The color is hidden, so that the colored portion formed by the colored pigment on the surface of the molded article becomes uneven in color, thickness, etc., and each plate becomes closer to a natural wood grain pattern.

And an attachment frame 19 attached to the outer surface (the surface of the living room). The plate body 18 is formed with a protrusion 20 projecting inward along one side edge along the longitudinal direction, and an attachment frame 19 is integrally formed on the other side edge.

The mounting frame 19 is a hollow plate formed so as to project to the side opposite to the projection 20, and is formed along the side edge of the mounting frame 19, and both ends thereof project from the plate body 18. It was formed by. The protruding portion 21 protruding from the plate main body 18 has a protrusion 45 on the side where the protrusion 20 is formed.
A cutting surface 21a cut at an angle of ° is formed,
As will be described later, the mounting surfaces 1 of which the cut surfaces 21a are adjacent to each other
It is a joint surface between 9 and 19. Further, the mounting frame 19 is provided with streak-shaped notches 22 on the inner surface of the mounting frame 19 from the edges thereof to the center of the mounting frame 19 on the plate body 18 side. These notches 22 are for engaging with a holding rod of the connecting member 16 described later.

The connecting member 16 is a hollow portion 19 of the mounting frame 19.
It is composed of a plate-like connecting plate 23 fitted to a and a holding rod 24 having the connecting rod 23 attached to one end thereof. The holding rod 24 has an L-shaped cross section as shown in FIGS. 3 and 4, and has a holding groove 25 formed along the lengthwise direction at each end. The sandwiching grooves 25, 25 sandwich the side edges in the lateral direction of the plate body 18 of each plate constituting the frame body 15, respectively. The connecting plate 23 is formed by cutting out one corner of a square plate in a square shape as shown in FIG. 4, and the peripheral portion of the cutout portion is joined to the end face of the holding rod 24. It was done.

The connecting member 1 having such a structure is provided.
6 is an exploded view of the main part of the wall storage rack 10 as seen from the rear side, and its connecting plate 23 is connected to the hollow portions 19a of the adjacent mounting frames 19 and 19, respectively. When the diagonal half of 23 is fitted and the holding rod 24 holds the side edges of the plate bodies 18 and 18 which are adjacent to each other at a right angle, the top plate 12 and the side plate 14, or the bottom plate 13 and the side plate 1 are sandwiched.
4 and 4 are connected in an orthogonal state. In addition, in the wall storage shelf 11 of the present invention, all of the top plate 12, the bottom plate 13, the side plates 14, and the shelf plate 17 are subjected to grinding treatment, and the finely divided cellulose particles and the resin having the white inorganic pigment carried on the surface thereof. And are mixed, and this is formed by extrusion molding.

The method for producing this molded article will be described below. The resin used for molding is vinyl chloride resin,
Examples thereof include phenol resin, polyethylene resin, polypropylene resin, ABS resin, polycarbonate resin, polyurethane resin and the like. Then, this resin is blended with cellulose-based fine powder particles that have been subjected to a grinding treatment and carrying a white inorganic pigment, and further if necessary known additives are blended and mixed, and then the mixture is extruded to form the mixture shown in FIG. Each plate is obtained by being molded into the shape shown in FIG.

As the material for obtaining the cellulose-based fine particles that have been subjected to the grinding treatment and carry the white inorganic pigment, various plant cells such as coarsely crushed wood, coarsely crushed bacas, and coarsely crushed rice straw are used. A material obtained by grinding a raw material material of the body is used. Here, the grinding process
This refers to a treatment that has both a crushing treatment and a polishing treatment, and it may be either a treatment in which the crushing treatment and the polishing treatment are carried out at the same time, or a two-step treatment in which the crushing treatment is followed by the polishing treatment. Good. That is, the grinding process here means a crushing process from a coarsely crushed product to a finely crushed product as described later, and finely pulverized powder particles are entangled in a fiber state, and the surface thereof is covered with cilia. This refers to a treatment in which a polishing process for polishing the surface so that the surface has a small amount of cilia, based on the powder particle shape.

In order to obtain a coarsely crushed material, the chips and the like are crushed by mechanical impact crushing to obtain 150 mesh,
Preferably, coarsely pulverized powder having a particle size smaller than 120 mesh is obtained. Here, for mechanical pulverization, for example, an impeller mill (IMP-250; manufactured by Seishin Enterprise Co., Ltd.) is preferably used.

The grinding treatment of the pulverized raw material is preferably performed by a ball mill shown in FIG. 6, for example. In this ball mill, a cooling jacket 2 is provided on the peripheral wall of an atmosphere-releasing mill body 1. Cooling water is circulated by supplying cooling water from a supply pipe 8 into the cooling jacket 2 and discharging it from a drain pipe 9. By doing so, the temperature inside the mill body 1 is set to a preset temperature, for example, 80 ° C. or lower.

Here, a motor 5 is arranged on the upper part of the mill body 1, and a rotor 4 for stirring the balls 3 in the mill body 1 is arranged on the bottom part of the motor 5. The rotor 4 is rotated by the drive of the motor 5 and agitates the ball 3 and the object to be ground to bring them into mechanical contact with each other. In addition, an outlet 7 that is opened and closed by a valve 6 is provided on the lower part of the cone of the mill body 1.
The material to be ground after the grinding processing can be discharged.

The balls 3 loaded in the mill body 1 of this ball mill are ceramic balls having an outer diameter of 3 mm to 5 mm,
In particular, it is preferable to use zirconia-based or alumina-based ceramic balls, and it is preferable to avoid using balls made of metal such as stainless steel and steel. This is because in the case of metal balls such as stainless steel and steel, crushed cellulosic powder such as wood powder may adhere to the surface of the balls, or the pulverized powder may be deteriorated due to heat generated by mutual contact between the metal balls. This is also because there is a possibility that fragments of metal balls or the like will be generated, and the fragments will be carried on the surface of the pulverized cellulose and become different from the desired fine powder particles. The dry ball mill may be either a closed type or an open type, but when the closed type is adopted, it is preferable to fill the mill with an inert gas such as nitrogen gas before use.

Further, in this ball mill, the used balls 3
In addition to the grinding treatment of the pulverized raw material as described above, the surface temperature of the raw material is adjusted to be in the range of 90 ° C to 120 ° C, and the room temperature of the mill body 1 is adjusted not to exceed 80 ° C. The drying process is also performed at the same time. Here, regarding the temperature control of the used balls 3, the capacity of the mill main body 1, the amount of the balls 3 put into the mill main body 1, the ball 3
The stirring speed, the cooling amount by the cooling jacket 2 provided on the peripheral surface of the mill body 1, and the like are adjusted based on the material and size, the temperature and amount of the charged pulverized material, and the water content.

Although the surface temperature of the ball 3 differs depending on the target material, for example, in the case of wood powder, the surface temperature is 100.
It is preferable to set the temperature in the range of ℃ to 120 ℃ from the viewpoint of grinding efficiency. However, when grinding takes a long time, it is preferably 90 ° C to 100 ° C from the viewpoint of preventing explosion.
In addition, if there is a danger of explosion in grinding,
The oxygen concentration in the mill body 1 is preferably within 15%, and in that case, for example, a method of continuously supplying nitrogen gas into the ball mill may be adopted.

According to such a grinding treatment by the ball mill, the internal temperature of the mill body 1 rises due to the frictional heat generated as the balls 3 rotate, while the cooling water circulated in the cooling jacket 2 causes the mill body 1 to circulate. By adjusting the internal temperature and the surface temperature of the ball 3 within the above range,
At the same time as the raw material pulverized product is pulverized and dried under a strong heating condition, the particle size is adjusted to a desired range, for example, 100 μm or less, and the water content is adjusted to 2.0 wt% or less. Is done. Further, according to this treatment, when the balls 3 come into contact with the raw material pulverized product charged in a coarse powder state, the raw material pulverized product contacting the balls 3 is pulverized into a fine pulverized product, and the surface thereof is Is ground into fine powder particles having a surface with very few cilia.

That is, the crushed raw material is mechanically crushed and abraded when it comes into contact with the surface of the ball 3 and crushed.
Since it is polished and heated and dried at the same time, the water content is efficiently removed. Moreover, since the fibers in the pulverized raw material are subjected to expansion and contraction by being repeatedly subjected to heating and cooling, they are rapidly dried when they are separated from the balls 3, so that the tips of the fibers are The parts are efficiently ground by the balls 3, and as a result, ground cellulosic fine powder particles having an independent particle shape with less cilia on the peripheral surface can be obtained.
Then, the cellulosic fine powder particles thus obtained are classified to have a particle size in a desired range (for example, 1 to 10 μm, 1
0 to 20 μm, 20 to 50 μm, 50 to 100 μm) to obtain a cellulose-based fine powder particle for supporting a white inorganic pigment.

Further, the grinding process of the crushed raw material can be carried out by using a crusher 30 as shown in FIG. 7 instead of the ball mill shown in FIG. This crusher 30
Is based on the principle of stone thinning, and is made up of two grindstones 31,
After the material 31 is opposed to each other through a predetermined gap and the raw material pulverized material is placed between them, one grinding stone 31 is rotated at a high speed to perform the pulverizing processing and the polishing processing, that is, the grinding processing.

Here, the grindstone 31 is of a dish type whose inner surface gradually inclines upward or downward as it goes to the central part, and these are wide in the central part and narrow in the peripheral part. They are arranged so as to face each other. As shown in FIG. 8, these grindstones 31 are donut plate-shaped with a mounting hole 32 formed in the center thereof, and a large number of feed grooves 33 ... Are formed on the inner surface thereof. The feed groove 33 is for reasonably guiding the object to be processed in the radial direction of the grindstone 31 by the centrifugal force generated by the rotation of the grindstone 31.

In order to grind the raw material pulverized product by such a pulverizer 30, the raw material pulverized product is put between the central portions of the two grindstones 31, 31, and then one of the grindstones 31 is driven at high speed. Rotate. Then, the raw material crushed product is gradually crushed by the centrifugal force, the impact force, the shearing force, etc. between the two grindstones 31, 31, and the feed groove 33 is crushed by the centrifugal force as the diameter becomes smaller.
... is moved to the outer peripheral side in the radial direction, and in the process, it is subjected to impact force and shearing force and crushed, and its peripheral surface (surface) is polished, and as a result, crushed to the peripheral surface. It becomes milled cellulosic fine particles with less cilia and an independent particle shape.

Then, the cellulose-based fine powder particles thus obtained are classified in the same manner as in the case of using a ball mill and the particle size is adjusted to a desired range.
It becomes a cellulose-based fine powder particle for supporting a white inorganic pigment. As the white inorganic pigment to be supported, titanium oxide, lithopone, white carbon, calcium carbonate, etc. can be used, but in particular, titanium oxide is the reason that sufficient whiteness can be imparted to the obtained molded article. Is preferred. Further, the particle size of the white inorganic pigment is adjusted to be sufficiently smaller than that of the cellulose fine powder particles.

As a method for supporting the white inorganic pigment on the cellulose fine particles, when the cellulose fine particles are obtained by the ball mill shown in FIG. 6, for example, the cellulose fine particles and the white pigment are mixed. Then, the resulting mixed particles are dispersed in the gas phase to impart mechanical thermal energy mainly composed of impact force to the particles, and the cellulose-based fine powder particles are used as the mother particles, and the pigment particles are provided on the peripheral surface of the mother particles. A method of supporting the is adopted. That is, this method is a method utilizing the fact that the pigment particles are harder than the cellulosic fine powder particles, and the pigment particles are infiltrated or bited into the surface of the cellulosic fine powder particles by such a difference in hardness. It can be supported in a closed state. The cellulosic fine particles obtained by the ball mill are subjected to the drying treatment at the same time as the grinding treatment as described above, so if the storage until the loading treatment is carried out, it is necessary to keep the dried state sufficiently. After the carrying treatment, the material can be subjected to a molding treatment described later without performing a drying treatment.

As another supporting method, when cellulose fine powder particles are obtained by using the crusher 30 shown in FIG. 7, mixed particles of the cellulose fine powder particles and the white pigment are shown in FIG. It is preferable that the white inorganic pigment particles are supported on the peripheral surface of the cellulosic fine powder particles by throwing them into a ball mill as described above and performing the grinding treatment again. This is because, in the grinding process by the ball mill, frictional heat is generated in the process of the grinding process as described above, and as a result, the drying process is simultaneously performed. That is, it is preferable that the white pigment-carrying cellulose-based fine particles have a low water content of, for example, about 3% by weight or less in the molding treatment described later in terms of molding, and thus it is desirable to perform a drying treatment in advance. However, when the supporting treatment is carried out by the ball mill method, the drying treatment is also carried out at the same time as the supporting treatment, so that the obtained supported fine powder particles can be directly subjected to the molding treatment.

By carrying out such a carrying treatment, the white inorganic pigment particles 50 are carried in the state of being bitten on the peripheral surface of the cellulosic fine powder particles 51 as shown in FIG. The amount of the white inorganic pigment to be supported is the upper limit of the amount that overlaps the peripheral surface of the cellulosic fine powder particles to be the base particles and covers the peripheral surface, but the lower limit is the desired amount of the molded product to be obtained. It is appropriately determined according to the whiteness.

The pigment-supporting cellulose-based fine powder particles thus obtained have a color tone almost the same as the color tone of the white inorganic pigment, and the agglomeration of the supported fine powder particles occurs both during the production process and during the storage process. I was not able to admit. Then, the pigment-supporting cellulose-based fine powder particles are mixed with the forming resin material and molded into the shape shown in FIG. 3 by the extrusion molding method, whereby each plate is obtained. Here, the blending amount of the fine powder particles supported on the resin is different depending on the type of the resin, for example, when using a vinyl chloride resin,
About 20 to 50 parts by weight of supported fine powder particles are mixed with 100 parts by weight of the resin.

In the molded product thus obtained, since the cellulose-based fine powder particles carrying the white inorganic pigment are subjected to the grinding treatment, for example, the one obtained by directly pulverizing the conventional wood into a fine powder is used. Unlike fibrous, it has a small number of cilia on the surface and becomes granular, so that it does not expand or contract due to adsorbing or releasing water (including moisture) or solvent like conventional fibrous wood powder. Therefore, each plate formed by containing this becomes extremely excellent in dimensional stability.

Further, since the cellulose-based fine powder particles, which have been subjected to the grinding treatment and which carry the white inorganic pigment on the surface thereof, are used as the aggregate, the adsorption and suction of the resin by the fine powder particles becomes extremely small, and the molding distortion occurs. Is almost gone. Then, the top plate 12, the bottom plate 13, the side plates 14, and the shelf plate 17 are obtained by imparting a woody appearance such as wood grain to the surface of this molded body. As a method of imparting a woody appearance, a general printing method may be adopted, but as described below, the surface of the molded body (the inner surface of the plate body 18 of each plate and the surface of the mounting frame 19) is ground. It is preferable to apply a coating material to the ground surface and to apply a paint to the ground surface because it gives a woody appearance very close to that of natural wood.

As such a wood-like imparting treatment, first, as a grinding treatment, the surface of the molded body is ground with a brush or baffle to make the surface to be coated rough, and part of the surface resin (skin layer). ) Is removed. Then, by such a grinding treatment, unnecessary irregularities generated during the molding are smoothed and many fine scratches are formed in the molded body.
The main purpose of this step is to eliminate the surface gloss, but especially when using a brush with a non-uniform tip, the surface roughening method becomes more or less strong, and color unevenness etc. may occur due to the coloring by coating described later. As a result, the wood texture can be further enhanced, and the penetration of the paint can be improved.

Further, in this case, the pigment-supporting cellulosic fine particles located on the surface portion by grinding the surface are the white inorganic pigments 50 carried on the surface as shown in FIG.
Is peeled off, and as a result, the inside of the cellulose-based fine powder particles 51 is exposed, and the wood texture of the surface of the molded body is enhanced. In addition, due to the unevenness of the whiteness of the surface due to such a grinding process, when the paint is applied as described later, there is a slight difference in the degree of suction of the paint and the degree of its paste.
Each of the obtained boards gives a layer of wood texture. Next, decoration processing by embossing is performed on the surface to be painted that has been ground. This embossing process puts a resin molded product between the punch and the die to form a wood grain-like uneven pattern,
This is a method of rolling a resin molded product between embossing rolls to continuously form a grain-like uneven pattern.

Then, a paint is applied to the embossed surface to make the wood grain pattern clear, and the excess paint on the coated surface is wiped off by a roll around which a non-woven fabric or the like is wound. Here, as the coating of the coating material, a conventionally known coating method such as a spray gun spraying method or various fluid immersion methods can be adopted. It should be noted that, as the paint, almost any resin used as a resin component in the paint can be used, but among them, urethane resin, acrylic resin, melamine resin, polyester resin and the like are preferably used. Further, as the pigment, in order to give a woody appearance, for example, a brown pigment such as iron oxide or a black pigment such as carbon is used.

Further, the coated surface is subjected to a well-known top coat treatment and, if necessary, cut into desired dimensions to obtain a top plate 12, a bottom plate 13, side plates 14 and a shelf plate 17 having a woody appearance. In addition, it is needless to say that the cutting for obtaining the desired size may be performed in advance at the stage of the wood-like plate material, that is, before the grinding treatment, and further before embossing.

The top plate 12 and the bottom plate 1 thus obtained
In the case of 3, the side plate 14 and the shelf plate 17, since the surface of the molded body was subjected to the grinding treatment, the white inorganic pigment-carrying cellulosic fine particles located facing the outer surface on the grinding treated surface were ground by the pigment-carrying portion. Then, the inner surface of the cellulosic fine powder particles faces the grinding processing surface. Then, the coating is applied to the grinding-treated surface facing the inner surface of the cellulosic fine powder particles, so that the coating material is directly sucked into the cellulosic fine powder particles, whereby the suction and the paste of the coating material to the molded article are good. Become. Furthermore, since the paint is sucked into the cellulose-based fine powder particles, the paint is microscopically spread on the plate material, and the wood pattern obtained by this is, for example, like a wood pattern by conventional printing. There is no unnaturalness where the shade of color becomes clear at the border of the pattern, and it becomes more natural.

The production of the top plate 12, the bottom plate 13, the side plates 14, and the shelf plate 17 is not limited to the above-described method, and, for example, the dough material pellets and the melting temperature of the dough material pellets are higher than those of the dough material pellets. Each plate shown in FIG. 3 may be molded by mixing wood-like forming material pellets at a predetermined ratio and extruding the pellet mixture. The dough material pellets are pellets obtained by mixing finely divided cellulose-based fine particles having a surface treated with a white inorganic pigment and a resin.

Various resins such as vinyl chloride resin, polyethylene resin, polypropylene resin, phenol resin, ABS resin, etc. are used as the resin constituting the pellets. Among them, vinyl chloride resin, polyethylene resin and polypropylene resin are more preferable. It is suitable.

The cellulose-based fine powder particles, which have been ground and have a white inorganic pigment supported on their surfaces, are used in the production of the above-mentioned molded products (top plate 12, bottom plate 13, side plate 14, shelf plate 17). The same one that was used is used. And
Such a white pigment-carrying cellulose-based fine powder particle and the powder of the resin are in an appropriate ratio, for example, a weight ratio, and the fine powder particle: resin = 3
Mixed in a range of 0:70 to 50:50,
Dough material pellets are obtained by pelletizing. Pelletization is performed by a conventionally known means such as extruding the mixed powder into a string shape from a porous circular nozzle and cutting the string.

The wood-like forming material pellets are pellets obtained by mixing resin-based and colored pigments with cellulose-based fine powder particles having a surface treated with a white inorganic pigment and subjected to grinding treatment. Its melting temperature is higher than that of pellets. Regarding the melting temperature, specifically, a temperature that is about 3% higher than the melting temperature (° C.) of the dough material pellets, for example, if the dough material pellets are 180 ° C., the wood-like forming material pellets are prepared in advance at about 185 ° C. To be done. here,
In order to raise the melting temperature of the wood-like forming pellets higher than that of the dough material pellets, known additives for increasing the melting temperature may be added, or the resin grade may have a higher melting temperature as described later. The method of substituting is adopted.

As the resin used as a component of the pellets, the resin used for the pellets of the dough material, that is, vinyl chloride resin, polyethylene resin, polypropylene resin or the like is used. When selecting the resin, it is naturally desirable to use the same type of resin as the resin used for the pellets of the dough material. As for the resin grade, another one can be selected so that the wood-like forming material pellets finally obtained have a higher melting temperature than the dough material pellets as described above. As the cellulose-based fine powder particles that have been subjected to the grinding treatment and the white inorganic pigment is carried on the surface, those obtained by the same treatment as that used for the dough material pellets are used.

Regarding the colored pigment, one or more kinds of inorganic pigments such as iron oxide, cadmium yellow, carbon black, etc. are desired, that is, the color of the fabric of the obtained product itself and the color of the wood grain pattern described later. Are appropriately selected and used. Then, the white pigment-carrying cellulose-based fine powder particles, the resin powder, and the colored pigment are mixed in an appropriate ratio and pelletized to obtain wood-like forming material pellets. Regarding the mixing ratio, the ratio of the white pigment-carrying fine powder particles to the resin powder is a weight ratio in the same range as that of the material material pellets, and the mixing ratio of the colored pigments is about 5 to 30% by weight of the whole. Note that pelletization is performed by a conventionally known means, as in the case of the dough material pellets.

The dough material pellets and the wood-like formed pellets are mixed, and the pellet mixture is molded into the shape shown in FIG. 3 by extrusion molding or injection molding, whereby the top plate 12, the bottom plate 13, and the side plates. 14 and the shelf board 17 are obtained. Regarding the mixing ratio of the dough material pellets and the wood-like forming pellets, the obtained top plate 12, bottom plate 13, side plate 1
4, it is appropriately determined based on the hue of the shelf board 17 and the ratio of the colored pigment in the wood-like forming material pellets, but normally, the material material pellets: the wood-like forming material pellets = 90: 10 to 99:
1 (weight ratio).

When extrusion molding a mixture of these pellets, the molding temperature is set in advance according to the melting temperature of the dough material pellets, and the molding time is also set according to the dough material pellets. When molding is performed under such conditions, the dough material pellets melt normally and flow uniformly in the molding direction. On the other hand, the wood-like forming material pellets are melted because they have a higher melting temperature than the dough material pellets, but the melting state is not sufficient as compared with the dough material pellets, and therefore the flow is poor and non-uniform.

As a result of such poor flow and non-uniformity, the colored pigments in the wood-like forming material pellets naturally do not flow evenly, and the molded product thus obtained has internal and internal properties as shown in FIG. Colored portions 34 with colored pigments are unevenly scattered in the surface layer portion. Further, on the surface of the molded body, the colored pigment 34 unevenly flows along the molding direction, so that the colored portion 34 appears in a streak shape as shown in FIG. 3, which is a pattern very close to a natural wood grain pattern. Moreover, particularly in the surface layer portion of the molded body, when the cellulose-based fine powder particles carrying the white pigment in the dough material pellets or the wood-like forming material pellets come on the colored portion 34, they are carried by the cellulose fine powder particles. Since the color of the colored portion 34 is hidden by the white pigment, the colored portion 3 visible on the surface shown in FIG.
4 (streak pattern) has uneven shading, which makes the colored portion 34 more like a natural wood grain pattern.

The top plate 12 and the bottom plate 1 thus obtained
3. The side plate 14 and the shelf plate 17 are obtained easily by mixing the dough material pellets and the wood-like pellets in an appropriate ratio according to the desired hue, and extruding or injection molding the mixture. In addition, the woody pattern has a light and dark stripe pattern, and the colored pigment in the woody pellets flows unevenly in the dough part as well, resulting in a non-artificial light and shade. It will be very similar to wood. In addition, when manufacturing such each plate, it is preferable to add an antiseptic agent or a fungicide in advance at the time of molding in order to enhance the durability. Also, if you add the essence of wood incense as a fragrance,
It is preferable because it creates an atmosphere closer to natural wood.

The top plate 12, the bottom plate 13, and the side plate 1 as described above.
4. In order to construct the wall storage shelves 11 using the shelves 17, first, the plywood 11e of the wall panel 10 as shown in FIG.
The gypsum board 26 is attached to the top and the inner surface thereof (the inner surface of the vertical frame 11a and the inner surface of the plywood 11c), and further, a cloth (not shown) is attached to the surface of the gypsum board 26. Separately from this, the top plate 12, the bottom plate 13, and the side plates 14, 14 are assembled in advance in a rectangular frame shape using the connecting member 16 at a factory or a construction site. In this assembly, the connecting plate 23 of the connecting member 16 is fitted into the hollow portions 19a of the adjacent mounting frames 19 and 19, and the holding grooves 25 and 25 of the holding rod 24 are orthogonal to each other and adjacent to each other. This is performed by fitting the side edges of 18, 18 and holding them.

Then, the frame body 15 assembled into a rectangular frame shape by the connecting members 16 is incorporated into the wall panel 10, and the predetermined positions of the side plates 14 and 14 are fixed by screws 27 with a cap as shown in FIG. 12, for example. Fix it. Then, the mounting frame 19 of each plate is attached to the gypsum board 26 attached to the plywood 11e of the wall panel 10 via a cloth. In addition, the screw 27 with a cap has a male screw formed on a head portion 27a of the screw portion, and a cap 27b having a female screw formed on the head portion is screwed. Furthermore, the side plates 14, 14
Screw 27 with a cap protruding above the side plate 14 in
Put the shelf board 17 on the cap 27c of the
Complete 1.

In the wall storage shelf 11 as described above, since the respective members such as the top plate 12, the bottom plate 13, the side plates 14, and the shelf plate 17 are obtained by extrusion molding similar to the case of resin, the workability is good. Therefore, the manufacturing cost is low and the price is low. In addition, since the cellulosic fine particles carrying the white inorganic pigment, which is the material for forming the top plate, bottom plate and both side plates, have been ground, for example, conventional wood is directly pulverized into fibrous form. However, unlike the conventional fibrous wood powder, it has very little expansion and contraction due to adsorbing or releasing water (including moisture) and solvent, unlike the conventional fibrous wood powder. Each plate formed by containing this becomes extremely excellent in dimensional stability. Furthermore, by using a fine aggregate of cellulose-based fine particles having a surface treated with a white inorganic pigment and subjected to grinding treatment, adsorption of resin by the fine particles can be achieved.
The suction is extremely small and molding distortion is hardly generated. Therefore, since each plate is excellent in dimensional stability and almost free from molding distortion, the wall storage shelf 11 composed of these plates also has excellent dimensional accuracy, and therefore, the construction such that it is integrally incorporated in the wall panel 10 is facilitated. Become.

Further, the connecting members 16 can easily connect between the mounting frames 19 and 19 of the plates and between the plate bodies 18 and 18.
Moreover, since the plate bodies 18, 18 are held by the holding rods 24, the connection between these plates can be strengthened, so that the wall storage rack 11 itself can be made solid despite easy assembly. . Further, if the top plate 12, the bottom plate 13, the side plates 14, and the shelf plate 17 are given a woody appearance, a wood texture very similar to a natural wood can be obtained, unlike the case where resin is simply printed with a wood grain pattern or the like. , This can give a high-class feeling.

In the above embodiment, the wall storage body of the present invention is applied to the wall storage wall. However, for example, the shelf 17 is eliminated to form a wall storage, or a door is attached separately to store clothes and the like. It may be used as a closet. Further, the back surface of the frame body 15 is not provided with a back plate, and the cloth is simply pasted. However, it goes without saying that a back plate may be provided. It can be manufactured in the same manner as the top plate 12, the side plate 14 and the like. Further, although the wall panel 10 is used as the wall in the above-mentioned embodiment, it goes without saying that a normal wall formed by a conventional method may be used.

As described above, the wall container according to the first aspect of the present invention is obtained by extrusion molding similar to the case where each member such as the top plate, the bottom plate and the side plate is made of resin. Machining of complicated shapes such as the structure of the mounting frame is facilitated, so that the manufacturing cost is low and the cost is low as a whole. Also, cellulosic fine powder particles carrying a white inorganic pigment, which is a material for forming the top plate, the bottom plate and the side plates, have been ground, and since these are used as aggregates, each plate has extremely excellent dimensional stability. And the molding distortion is almost eliminated. Therefore, the wall storage body composed of these is excellent in dimensional accuracy and can be easily assembled into a wall.

In the wall storage body according to the second aspect of the invention, since the connecting frames can easily connect between the mounting frames of the plates and between the plate bodies, the connection between the plates can be strengthened. The wall storage itself becomes solid even though the connection and assembly are easy. According to a third aspect of the present invention, in the wall storage body, the top plate and the bottom plate side plates have irregular and non-uniform flow of the colored pigment in the wood-like forming material pellets due to the difference in melting temperature between the dough material pellets and the wood-like forming material pellets. In addition to the formation of streak colored parts, the dough itself is also unevenly colored, and since the streak colored parts have a wood grain pattern very close to the natural grain, the surface is extremely It has a natural woody appearance. Moreover, since the cellulosic fine powder particles in each pellet carry a white inorganic pigment on the surface thereof, in the obtained molded product, the fine powder particles come closer to the surface side than the colored pigment, thereby making The color is concealed, so that the colored portion of the surface of the molded body formed by the colored pigment becomes extremely uneven in color and thickness, and has a woody appearance closer to that of a natural material. Therefore, since the wall storage body of the present invention has a surface extremely close to natural wood,
It will create a feeling of luxury and calm in the room where this is installed.
