Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a felt material for educational toys which has a predetermined durability against rough use of an infant and is safe even if the infant is bent or put into a mouth.

[0002]

2. Description of the Related Art Educational toys for babies and infants have recently been occupying a certain position in the field of the educational industry as a variety of articles have been sold with the declining educational age in recent years. Conventionally, cardboard is used as a material for building blocks and puzzles, which are a type of educational toys. The cardboard educational toys have a low elastic deformation value, and have a problem that when a child bends a block, it easily deforms permanently and does not return to its original shape, and is easily broken and lacks durability.

[0003] At present, plastics are often used as educational toys, and at least the durability has been considerably improved. Since plastic educational toys have high water resistance and a high elastic deformation value, they are unlikely to be torn or permanently deformed even when put into the mouth by infants. In addition, rare materials such as metal and wood are also rare as special materials.

[0004]

Although educational toys made of plastic are considerably more durable than those made of paper, they are often damaged when an infant throws or steps on the toy against a wall. If the plastic material breaks, the fracture surface becomes sharp and very dangerous, and in fact, infants have been injured by plastic fragments, causing problems.
With the enactment of the L Law, there is a tendency to avoid using plastic in educational toys. Although metal and wooden educational toys are superior in terms of accident occurrence, these materials are generally too heavy and too expensive for infants to handle.

[0005] The present invention has been proposed to improve the above-mentioned problems relating to the materials of educational toys, and it is possible to immediately return to its original shape even if it is bent many times, and to be broken even if thrown or stepped on by an infant. It is an object of the present invention to provide a felt material for educational toys having little. Another object of the present invention is to provide a felt material for educational toys that is lighter in weight and easier for infants to handle than plastic, metal or wooden educational toys.

[0006]

In order to achieve the above object, the felt material for educational toys according to the present invention is made of synthetic and / or natural fibers such as wool, acrylic fiber and polyester fiber, and is based on toy standards. The felt is colored with a dye which has a fastness to pass and has no oral toxicity. The felt is impregnated with a resin having no oral toxicity and about 30% by weight or more of owf and dried. The resin is, for example, a natural resin that does not produce formalin or a vinyl acetate resin, a rubber resin,
An acrylic or urethane resin is used.

In the felt material of the present invention, as shown in FIG. 2, it is preferable to use two felts dyeing the same color or different colors. It is necessary that each felt is impregnated with a resin having no oral toxicity of about 30% by weight or more and owf and dried, and then two pieces of felt material are bonded with a heat-fusible film or resin interposed therebetween.

When the educational block is made of a two-layer felt material, as shown in FIGS. 1 and 2, it is preferable that the felt material be made of two felts dyed in the same color or different colors. The two-layer felt material is punched into a large number of sections that are predetermined polygonal planes, and each section has two or more insertion grooves or holes.

When the educational puzzle is made of a two-layer felt material, as shown in FIG. 7 or FIG. 8, the felt material is preferably composed of two felts dyed in different colors. In the two-layer felt material, a notch having a line-symmetrical planar shape can be formed, and each cut portion can be turned over and fitted.

[0010]

DETAILED DESCRIPTION OF THE INVENTION In the felt material of the present invention, the felt used is colored with a dye having a color fastness that meets toy standards and having no oral toxicity. In general, wool felt is dyed with a basic dye that dissolves easily in water and has a cationic dye, and dyes directly on wool fibers in a neutral to weakly acidic bath. It is preferable because it has excellent fastness among dyes, and acrylic fiber can be dyed similarly. In addition, for dyeing polyester felt, in addition to the above-mentioned cationic dye, high-temperature dyeing using a disperse dye and without adding a toxic carrier may be performed, and the high-temperature dyeing has a good dark color and high friction fastness. .

The resin to be impregnated and dried in the felt is used in order to prevent permanent deformation when the felt is bent many times, and is also a natural resin or a vinyl acetate-based, rubber-based resin which is not orally toxic and does not produce formalin. It is preferable to use an acrylic resin or a urethane resin. The impregnation amount of the resin is about 30% by weight or more, preferably about 50% by weight or more to increase the value of elastic deformation. The impregnation amount of the resin is preferably not more than about 80% by weight owf because the felt becomes too hard and uneconomical even if it is too large.

[0012] The colored felt material may be light or medium color, but may be red, green, yellow, blue, light blue, brown,
It is preferable to dye in dark colors such as black, pink, gray and white. This colored felt material has a thickness of 2 to 10 for example.
mm, and may be punched into a large number of squares (FIG. 3) or regular hexagons (FIG. 1) in order to form an educational block as it is. The shape of this block may be a deformed plane such as a triangle, a pentagon, an octagon, a circle, a star, or an ellipse, in addition to the square or hexagon (FIG. 1) as shown.

[0013] The colored felt material has different colors on the front and back.
If it is a layer felt, the thickness of each felt is 1-5m
m, and both felts may be attached with a heat-fusible film or resin interposed therebetween. Fig. 1 shows two layers of colored felt material.
It is suitable to be used for the educational block illustrated in FIG. 6 or the inset puzzle illustrated in FIGS. 7 and 8, and can be applied to a perpetual calendar or jigsaw puzzle for infants as the inset puzzle.

[0014]

Next, the present invention will be described based on examples, but the present invention is not limited to the examples. The felt used in the present invention is colored with a cationic dye having a color fastness that passes toy standards and has no oral toxicity. Felt colored with a cationic dye is wool, acrylic fiber, polyester fiber, or the like, and polyester fiber is a commercially available product.

For example, when dyeing wool felt in a deep red color, firstly, a cationic dye (trade name: Katilon, manufactured by Hodogaya Chemical Industry Co., Ltd.) is kneaded with a small amount of acetic acid (60%), and then about 50 times. Add boiling water to dissolve. on the other hand,
The following dyeing aid is added to the 50 ° C. bath. Sodium acetate 2% by weight Acetic acid (60%) 1% by weight Anhydrous sodium sulfate 5% by weight Water remaining

[0016] Wool felt is put in the above bath at 50 ° C.
After the treatment, the cationic dye dissolved in advance is injected, the temperature is raised to 85 ° C. in 15 minutes, and the temperature is further raised to the boiling point for dyeing for 100 minutes. After dyeing, it is cooled to around 60 to 80 ° C. and then water-cooled. Blue, green, yellow, black, etc. can be dyed in the same way, the amount of cationic dye used is light color,
10 g to 10 kg are added depending on the medium color and the dark color.

In addition, when polyester fibers are dyed at a high temperature with a disperse dye, a commercially available disperse dye having no oral toxicity is dispersed with an anionic activator to make the bath weakly acidic. The bath may be dipped with polyester fibers and treated at about 130 ° C. for 45 to 60 minutes to dye a deep color. If dyeing is performed at a dyeing temperature of about 120 for 30 to 45 minutes, a disperse dye can be dyed from a light color to a medium color.

The obtained colored felt is immersed, for example, in a resin solution having the following composition without oral toxicity. Urethane resin (manufactured by Daiichi Kogyo Seiyaku Co., Ltd.) 30% by weight Vinyl acetate resin (manufactured by Showa Polymer Co., Ltd.) 20% by weight Water 50% by weight This resin is 35 to 40% by weight owf in dry weight on felt.
By impregnating and drying as described above, the felt has a high elastic deformation value and easily returns to its original shape.

The obtained felt material is dyed in a dark color such as red, green, yellow, and white for children.
５5 mm. As shown in FIGS. 3 and 4, a large number of educational blocks 1 are punched from the colored felt material. The block 1 is a square having one side of 3 to 5 cm, and the insertion groove 2 is formed at a right angle to the center of each side. Each insertion groove 2 has a width slightly smaller than the thickness of the block 1, and the groove depth may be about 1/4 of the length of one side of the block.

As illustrated in FIG. 4, when the grooves 2 of the respective blocks 1 are inserted into each other, the blocks 2 are spread in a bar shape or a planar shape, so that a child can assemble a house or a bridge in a disassembled manner. In order to connect the blocks, in addition to the insertion grooves as shown in the figure, mutual combinations of tile-like blocks 5 provided with shredded projection grooves 3 around the periphery as shown in FIG. Any type using a metal joint may be used. When the blocks 1, 5 and the like are sold, it is often the case that a large number of differently colored ones are set and packed in a box.

The single-layer felt material may be punched into a circular sheet 7 having a large number of through holes 6 provided at equal intervals around the periphery as shown in FIG. The circular sheet 7 in FIG. 6 is an educational toy in which the colored thread 8 can be passed through the through-hole 6 as shown in the drawing, and the baby can freely play with the decoration of the picture. I do.

The educational block 10 shown in FIGS. 1 and 2 uses two felts 11 and 12 dyed in different colors such as red and green, red and yellow, and red and black. Thickness 1-3
mm felts 11 and 12 are impregnated with a commercially available resin having no oral toxicity and about 30% by weight owf or more and dried.
The felts 11 and 12 are attached with a heat-fusible film or resin interposed therebetween. Further, the two felts to be adhered with a heat-fusible film or the like may be the same color. If a melted and solidified heat-fusible film or resin is interposed between two felts,
Since the value of the elastic deformation of the block 10 is considerably high, permanent deformation is difficult, and if the same mechanical strength is sufficient, the amount of the impregnated resin can be reduced.

A large number of educational blocks 10 can be punched out of the two-layer felts 11 and 12 adhered to each other. The block 10 is a regular hexagon having one side of 1 to 3 cm,
An insertion groove 13 is formed at a right angle to the center of each side. Each insertion groove 13 has a width slightly smaller than the thickness of the block 10, and the groove depth may be about １ ／ of the length of a perpendicular from the center of the block to the side.

The educational fitting puzzles 15 and 16 shown in FIG. 7 or FIG. 8 are mainly for infants, and are composed of a two-layer felt bonded. In puzzles 15 and 16, 2
Cuts 19 and 20 which are line-symmetrical plane shapes are made in the layer felt material 17 or 18, and the cut portions 21 in FIG. 7 correspond to the shape of the vehicle as a whole, and the cut portions 22 in FIG. It is a geometric pattern such as a rhombus, polygon, or circle, or a flower or star. Felt material 17
Alternatively, an appropriate support sheet (not shown) is attached to the entire back side of the or 18. If desired, a suitable printed pattern 23 may be applied.

In the puzzles 15 and 16, when the infant raises the individual cut portions 21 and 22, turns them over, and fits them again, a color-changed graphic can be obtained. Notches 21 and 22 to change the color
May be previously fitted with a two-layer felt piece dyed in another color.
8 may be a single-layer felt.

Although not shown, another variation of the educational fitting puzzle is a perpetual calendar for infants. This perpetual calendar has a long and narrow groove 5 to 5
It has six rows of sheet bodies, and a square felt material can be fitted into each groove to arrange seven sheets. The square felt material is made of, for example, two layers of red and yellow felts, each of which is solid or printed with a large number of 1 to 31. When playing with this perpetual calendar, square felt material is fitted from the top row of grooves on the sheet body, but until the position corresponding to the first day of the month of the month, a plain square felt material is inserted, and it is equivalent to the first day of the week The square felt material of the number 1 is put in the position to be performed, and the numbers of the square felt material are arranged in the following. The square felt at the position corresponding to Sunday flips over and reveals a red surface. If two types of two-layer felt materials of red and yellow and blue and yellow are used, the square felt material at the position corresponding to Saturday is turned upside down to give a blue surface.

As yet another modification of the educational fitting puzzle, there is a jigsaw puzzle (not shown) for an infant. This jigsaw puzzle is made of a two-layer felt material lined with a sheet, and an appropriate pattern is printed on the front side or the back side. Appropriate cuts are made in the two-layer felt material to separate pieces of felt, and when these pieces are fitted in the correct positions, one pattern is completed. Since this jigsaw puzzle is made of a two-layer felt material, it can be fitted on both sides, and if it is a single-layer felt, it is the same as a normal jigsaw puzzle.

[0028]

The felt material according to the present invention is obtained by impregnating a synthetic and / or natural fiber felt with a resin having no oral toxicity and drying it, so that a toy using the felt material can be used as a plastic toy. Compared to the high durability of the infant, even if it is bent and bent many times due to the rough use of the infant, it will immediately return to its original shape without permanent deformation, and will hardly be deformed or broken by the throwing, stepping or pulling of the infant. The toy made of this felt material is soft even when the infant hits or stomps on others, so it is not injured.Even if it is deformed or damaged, its end face is made of a soft fiber. The child is safe without being hurt.

The felt material of the present invention is colored with a non-orally toxic dye and impregnated with a non-orally toxic resin, so that an infant can safely lick a toy or put it in his mouth,
Moreover, since it has a color fastness that meets the toy standards, there is little discoloration over time. Also, toys using this felt material are much lighter and cheaper than metal or wooden toys, and are often cheaper than plastic toys.
