Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a gymnastics carpet used for rhythmic gymnastics competitions or exercises, and is particularly delicate using balls, rings, ribbons, ropes and clubs and The carpet developed for rhythmic gymnastics, which requires bold expression.

(Prior art) Conventionally, at a FIG competition or a competition similar thereto, nylon is densely planted in a polyester fiber base fabric, and a synthetic jute or sponge board is backed on the back face of the base fabric. Carpets with timber were widely used. This structure makes it possible to considerably prevent accidental injuries such as fractures and severe bruises as compared to acting directly on the floor.

(Problems to be solved by the invention) However, in the conventional carpet as described above, the density of planting the nylon fiber on the base fabric is very large, and therefore slippage during rapid leg opening and slippage during toe spin turns occurs. There is a shortage, which hinders the development of highly difficult techniques, and is unsuitable for diversifying the composition of acting, and there are problems such as rubbing and causing burns. In addition, since the plain weave base cloth is directly attached to the backing material, it causes deformation and swells up in places where it is used frequently or receives a large amount of force. There were also problems such as irregular rolling of balls and wheels.

The present invention has been devised in view of the above-mentioned problems of the prior art, and has excellent motility so that the performer can run, skip, jump, etc. as he / she desires, and further, quick-open legs and spin-turn of the toes. Sometimes it gives a proper amount of sliding, does not cause burns due to rubbing, does not deform even with vigorous exercise, and has excellent dimensional stability, using various hand tools, especially rolling wheels and balls according to image, It is an object of the present invention to provide a rhythmic gymnastics carpet having excellent fluffing property, flatness, and durability that can perform delicate and bold expressions easily and safely including performances such as returning to.

(Means for Solving the Problem) Means for achieving the above-mentioned object is to be laid as the uppermost layer of the rhythmic gymnastics performance surface, and 25 to 80 nylon filaments are used for the polyester or polypropylene base cloth. , And a heat-set pile of the bundle is planted, and a backing material such as natural jute is attached to the back surface of the base fabric on which the pile is planted, such as a rubber-based latex. In a rhythmic gymnastics carpet made by adhering with an adhesive, the base cloth is a polyester non-woven fabric or a polypropylene non-woven fabric, and the pile is 4 to 8 m.
Level cut to a finished length of m and 9 to 15 laterally
Books / 2.54 cm (inch) and 9 to 16 books / 2.54 cm (inch) in the lengthwise direction are planted on the non-woven base fabric, and the pile is fixed on the back surface of the planted base fabric. A carpet for rhythmic gymnastics, wherein a cured adhesive layer is formed on the cured adhesive layer of the backing material.

(Function) Among the rhythmic gymnastics carpets having the above-mentioned structure, those using a base fabric made of a polyester non-woven fabric or a polypropylene non-woven fabric are excellent in dimensional stability, that is, the tensile strength and the elongation in the longitudinal and transverse directions are 115 kgf or more, respectively. , 6% or less and 84
Above kgf and below 3.5%, wrinkles do not occur even when the performer's intense exercise is performed, and it is possible to maintain a flat playing surface and withstand long-term use. In addition, 25 to 80 nylon filaments are bundled, 2 or 3 of these bundles are heat-set, and the pile is level-cut to a finished length of 4 to 8 mm. Having resilience and flexibility, 4-8m
Combined with the finishing length of m and 9-15 pieces / 2.54 cm (inch) in the horizontal direction, and 9-16 pieces / 2.54 cm (inch) in the vertical direction, it is easy to spin-toe and quickly open the toes with the difference in the planting density. In order to prevent the player from getting burned, he / she will exhibit moderate slippage, and if he / she is always uniform, he will maintain a competitive standing surface and eliminate inadvertent slippage, making it easy for the performer to perform heavy exercise such as running, skipping, and jumping. To do. At the same time, 4-8m of the pile
Instant standing recovery of piles when stepped on by a short level cut of m and a large planting density of 9 to 15 lines / 2.54 cm (inch) in the horizontal direction and 9 to 16 lines / 2.54 cm (inch) in the vertical direction. The irregularity of the rolling of the equipment and the rolling of the ball is eliminated by greatly improving the softness, uniform fluffing and the recovery and maintenance of the flatness, which enables the performance as the performer imagines. Further, a rubber latex adhesive is applied once to the pile for fixing the pile on the back surface of the base cloth in which the nylon pile is planted, and after drying, a backing material such as natural jute is attached again with the adhesive. Therefore, the pile pull-out strength is 2.4 kgf or more, and the backing material peeling strength is 1.9 kgf or more and 2.3 kgf or more in the vertical and horizontal directions, respectively. Can withstand repeated cleaning with a cleaner.

Embodiment An embodiment of the rhythmic gymnastics carpet of the present invention will be described below with reference to the drawings.

FIG. 1 is a vertical sectional view showing the basic structure of the rhythmic gymnastics carpet of this embodiment, FIG. 2 is a vertical sectional view of a laminated structure when the carpet is used for rhythmic gymnastics, and FIG. 3 is the same. It is a top view showing the state where a carpet was laid on the performance side of rhythmic gymnastics.

 In FIG. 1, a rhythmic gymnastics carpet 100 of the present invention is shown.
Is a base made of polyester spunbonded nonwoven fabric.
Cloth 120, with a high strength nylon filament, for example
Leona 66 of Asahi Kasei Corporation Nylon 66 (nylon 10
40% of 0% BCF) is bundled to make a 800 denier bundle.
2 pieces are twisted and spell bar heat set, 6mm finish
1600 denier pile level cut to length 1
10 in the horizontal direction 11.3 ± 0.5 / 2.54 cm (inch), in the vertical direction
Planted with a vertical and horizontal difference at a density of 10 pieces / 2.54 cm (inch)
And a rubber-based material on the back surface of the base cloth 120 in which the pile 110 is planted.
Apply latex adhesive 130 and dry to remove pile 110
It is fixed. By the way, pile weight is used in this example.
650g / m²Has become. Plain weave as backing
(13 / 2.54 cm (inch) in the horizontal direction, 10 / 2.54 cm in the vertical direction)
(Inch density) natural jute 140 is further adhered
Agent 130 is applied and attached.

By the way, the adhesive 130 is a rubber-based special SBR latex, and the pile pull-out strength (autograph tensile tester) is
2.43kgf, jute peel strength (Shopper type tensile tester) was 1.97kgf in the longitudinal direction and 2.34kgf in the transverse direction.
Natural jute (burlap) has the longest fiber length (1 to 4 m) among natural fibers, has little expansion and contraction, and has excellent dimensional stability and strength. As a result, the longitudinal and lateral tensile strength and elongation (autograph tensile tester) of the rhythmic gymnastics carpet 100 were 115.3 kgf and 5.9 respectively.
% And 84.5 kgf, 3.4%, and the tear strength in the longitudinal direction and the transverse direction (autograph tensile tester by the Trabezoid method) are respectively
It was 35.5kgf and 27.9kgf. Further, the carpet 100 is subjected to antistatic treatment.

As shown in FIG. 2, the carpet 100 for rhythmic gymnastics having the above-described configuration has a polyethylene vinyl acetate copolymer resin foam (expansion ratio 14 to 15 times, tensile strength 9.6 kg / cm ² , repeated 25% compression). Permanent strain 1.0%, impact resilience 54.6%) 1
It is laid on a 0 mm thick elastic mat 210 and rhythmic gymnastics yuka 20
Configure 0. The elastic mat 210 of the polyethylene vinyl acetate copolymer resin foam and the carpet 100 laid on the elastic mat 210 cooperatively absorb the external force when landing on the entire sole of the foot to eliminate the feeling of bottoming. Along with this, it mitigates the impact force on the body during falls, forward rolls, and rotations, and prevents fractures and bruises. Also, unlike the gymnastics, this carpet 100 is prohibited from acrobatics, and provides moderate frictional resistance to movements such as running, jumping, and skipping by a relatively gentle girl while opening legs, With respect to a motion such as a spin turn in which the body is slid in contact with the carpet 100, sliding can be obtained more easily than in the case of the gymnastics carpet. More specifically, the pile length is 4-8m
The pile 110 is level cut to a finished length of m and has a relatively dense planting density in the longitudinal direction of the carpet 100.
It prevents the toes from slipping inadvertently due to the frictional resistance of the pile 110, and the pile 110 having a relatively high laterally dense pile planting density and the excellent resilience can be twisted and fallen to obtain appropriate slipperiness. Since the carpet 100 inevitably acts like a bullet on the bounce of the ball, the elastic mat 210 acts on the bounce of the ball in a complementary manner to obtain a bounce of the ball which is almost the same as on the true floor F. You can do it. In addition, since the base material 120 of polyester, the hardened layer 130 of the rubber-based latex of double coating, the backing material 140 of jute, etc. are used in a large size, there is no wrinkle on the performance side and it is always flat. It is possible to maintain a good state, and it is possible to maintain a good state without the pile 110 coming off as described above. Further, since these materials are also excellent in waterproofness, it is possible to appropriately clean them with a carpet cleaner or the like.

As shown in FIG. 3, the rhythmic gymnastics carpet 10 of the present invention
The 0 division is a 12m square acting surface 301 (for example, beige color), and a perimeter 50cm wide admissible additional surface 302 for group acting.
(For example, orange) and the safety zone 303 (for example, yellow) with a width of 75 cm on the outer periphery of it, and is divided into four partial carpets A, B, C, D due to storage restrictions after use. (Shown by dividing lines a, b, and c). Due to the limitation of the dyeing work, the part of the performance surface 301, the additional surface 302 part of the outer periphery thereof, and the safety zone 303 part are separately formed and joined by seaming adhesive (seaming adhesive line is indicated by z). The additional surface 302 and the safety zone 303 are color-coded by simultaneous dyeing but not divided, but the additional surface 302 and the safety zone 303, which form a rectangular frame shape, are formed separately on each side. The four corners are seamed along the L-shaped joining lines to form a frame shape.

Partial carpet divided into 4 pieces thus made
A, B, C, D are combined on an elastic mat 210 (for example, 14 pieces having a width of 1 m, a length of 14 m, and a thickness of 10 mm are combined) laid 14.0 m square on the true floor F. And then joined. Joining is done by combining the width of both female Velcro tapes with the female Velcro tape of 50 mm width attached to each back side of the adjacent edges of each divided partial carpet A, B, C, D.
It is done using a male Velcro tape of 4.5 m length and 100 mm width, first laying the divided carpet parts A, B, C, D in a regular state on the elastic mat 210 without using the male Velcro tape, Next, a male velcro tape is stretched along the joining line of the adjacent edges of each carpet, and the edge of one of the divided carpets is turned over to drop half of the male velcro tape on the elastic mat 210 and the back side of the edge. The female velcro tape is joined, and then the other adjacent edge is turned over to drop the other half of the male velcro tape on the elastic mat 210 and join the female velcro tape on the back side of the edge.
The elastic mat 210 is installed and set with respect to both the true floor F and the male velcro tape and the carpet 100 by a large frictional force without being stably displaced.

(Effects of the Invention) As described above, according to the rhythmic gymnastics carpet of the present invention, the tensile strength, the dimensional stability, and the pull-out are obtained by the double coating of the base fabric made of the polyester nonwoven fabric or the polypropylene nonwoven fabric and the adhesive such as the rubber latex. The strength is dramatically improved, wrinkles do not occur even when the performer's intense exercise is performed, and it is possible to maintain a flat acting surface at all times and withstand long-term use. In addition, 25 to 80 nylon filaments are bundled, and this bundle is twisted 2 or 3 and heat set to level cut to a finish length of 4 to 8 mm and 9 to 15 /2.54 cm (inch) in the lateral direction. ), The piles with a planting density of 9 to 16 / 2.54 cm (inch) in the vertical direction have greater elastic recovery and suppleness, and even immediately after the performer steps or kicks. While maintaining a uniform fluffy performance surface, it is possible to improve the performance by enabling the operation of the equipment, especially the ring and the ball, as expected, and at the time of the fall, the performer does not get scratches or burns. Protect your body so that you will not receive it. The pile is level cut to 4 to 8 mm and 9 to 15 in the lateral direction / 2.
54 cm (inch), 9 to 16 pieces vertically / 2.54 cm (inch)
Different from the other, it is planted on the base cloth relatively honey, and it is twisted and heat set to have excellent elastic recovery, so it is necessary to slide on the carpet such as open legs or spin turns. In addition to providing moderate slipperiness, the instability of the performance due to excessive slippage can be prevented at the same time. Furthermore, the back surface of the base cloth is fixed and piled again with an adhesive such as rubber-based latex, and then reapplied. It is also excellent and can be properly cleaned with a carpet cleaner, which helps improve hygiene. Thus, the performer can easily and safely perform delicate and graceful and bold expressions using various kinds of hand tools, and greatly contribute to the development of new techniques and diversification of acting.
