Description

Exercise gaiters and its manufacturing method {STATS AND IT MANUFACTURE METHOD FOR SPORTS}

TECHNICAL FIELD The present invention relates to athletic gaiters, and more particularly, to a method for manufacturing gaiters of high impact absorption and high strength using polyester-based nonwoven fabrics.

Typically, all sports, such as football, rugby, hockey, taekwondo, etc. must use gaiters to protect the shin of the athlete, which is usually made in two ways.

The first method is to apply an adhesive to both sides of the curved plastic injection molding, and then attach urethane foam sheet and nylon fibers to the plastic injection molding in turn, or urethane foam sheet and nylon fibers to the plastic injection molding. It is manufactured by sewing the integrally.

However, the use of plastic injection moldings in gaiters produced in this way has the disadvantage that the production process is complicated. In addition, the gaiters have a problem that the adhesive layer is released or the sewing line is damaged when the long-term use is reduced durability.

In a second method, a urethane foam sheet and nylon fibers are sequentially attached or sewn to both sides of a flat aluminum plate.

However, this is an aluminum plate that is bent at the time of impact can not be reused, and also has a disadvantage in that the shock absorbency is lowered causing pain. In addition, since the manufacturing method uses aluminum, not only the cost is increased, but the manufacturing process is complicated, and durability may be degraded due to glass phenomenon or damage to the seam of the adhesive layer when used for a long time.

Accordingly, an object of the present invention for solving the above problems is to provide a high impact absorbing and high strength exercise gaiters and a method of manufacturing the same.

It is another object of the present invention to provide a method for producing a sports gaiters, in which the adhesive layer of gaiters is not free.

Still another object of the present invention is to provide an exercise gaiter manufactured by inserting a polyester-based nonwoven fabric without using plastic or an aluminum plate.

Still another object of the present invention is to provide an athletic leggings with an embossed pattern protruding from the entire surface.

The present invention according to the first check for achieving the above object, the urethane foam sheet and nylon fibers are laminated and attached to both sides of the polyester-based nonwoven fabric, and then pressurized by pressing, and the fabric is a predetermined temperature Eggplant is preheated to about 80 ~ 90 ℃ in the heating room, and then pressurized for 30 to 60 seconds at a pressure of about 5 ~ 10kg / ㎠ with a rounded upper / lower mold to produce a high impact absorbing gaiters It was.

More preferably, it has a polyester-based non-woven fabric, the urethane foam sheet and nylon fibers are laminated and attached to both sides of the polyester-based nonwoven fabric, embossed exercise gaiters formed on the entire surface of the embossed pattern.

Figure 1a to 1d is a schematic diagram showing a method of manufacturing a workout gaiters according to a preferred embodiment of the present invention.

Figure 2 is a perspective view showing the shape of the athletic gaiters manufactured according to an embodiment of the present invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, it should be noted that only parts necessary for understanding the operation according to the present invention will be described, and descriptions of other parts will be omitted so as not to obscure the subject matter of the present invention.

First, the manufacturing apparatus for making gaiters of the present invention, as shown in Figures 1b and 1c, the heating room 10 is provided with a fan 12, the upper and lower molds 18, 24 for forming the gaiters, and the mold It consists of a hydraulic cylinder 16 pressurized at a pressure of.

That is, the heating room 10 has a different temperature at the inlet and outlet, preferably the inlet maintains a temperature of 40 ~ 50 ℃ and the outlet maintains a temperature of about 100 ~ 150 ℃. And the conveyor belt 14 is installed below the heating room 10, which serves to move the compound 200 to be described later into the heating room 10.

The mold consists of an upper mold 18 formed by bending along the inner circumferential surface and a lower mold 24 having a rounding surface 25 protruding along the outer circumferential surface. In this case, grooves 20 are formed on the inner circumferential surface of the upper mold 18 to form protrusions 302 on the surface of the gaiters 300. Preferably, the grooves 20 are for forming an embossed pattern on the surface of the gaiters 300. In addition, the rounded surface 25 of the lower mold is to bend the inner surface of the gaiters 300 inward, that is to be formed to bend the gaiters 300.

And the upper end of the upper mold 18 is connected to the piston rod of the hydraulic cylinder 16, the lower mold 24 is fixed to the press bed 22. At this time, the hydraulic cylinder 16 presses the upper mold 18 at a pressure of about 5 ~ 10kg / ㎠.

Meanwhile, a method of manufacturing a high impact absorbing athletic gaiters using the gaiters manufactured as described above will be described with reference to FIGS. 1A to 1D.

First, as shown in FIG. 1A, an acrylic adhesive is applied to both sides of the polyester nonwoven fabric 104, and then the urethane foam sheets 104 and 106 are adhered to each other, and then an acrylic adhesive is also applied to one surface of the urethane foam sheets 104 and 106. Next, the nylon 100 and 108 are bonded together. The press 200 is then pressed in a conventional press to produce composite 200.

Subsequently, when the composite material 200 is placed on the upper end of the conveyor belt 14 as illustrated in FIG. 1B, the composite material 200 is introduced into the heating room 10 by the operation of the conveyor belt 14. The composite 200 is then gradually warmed up by the internal temperature of the heating room 10, preferably 40-50 ° C., and then discharged to the outside of the heating room 10 while being preheated by the temperature of 150 ° C. At this time, the composite 200 is preheated to a temperature of about 80 ~ 90 ℃.

Next, the composite 200 having undergone this process is placed on the rounding surface 25 of the lower mold, as shown in FIG. 1C, and then the hydraulic cylinder 16 is operated. Then, the piston rod 16a moves the upper mold 18 downward by the operation of the hydraulic cylinder 16, whereby the upper mold 18 and the lower mold 24 are coupled.

Thereafter, the hydraulic cylinder 16 presses the upper and lower molds 18 and 24 for about 30 to 60 seconds at a pressure of 5 to 10 kg / cm 2 as shown in FIG. 1D. Then, the composite 200 is formed into a gaiters 300 rounded at a predetermined angle with the projections 302 having an embossed pattern on the surface, as shown in FIG. 2. At this time, the protrusion 302 formed on the surface of the leggings 300 increases the shock absorbency and improves the strength to protect the athlete from the impact.

As described above, the present invention can lower the manufacturing cost of gaiters by using a polyester nonwoven fabric instead of plastic or aluminum plate, and also has the advantage of minimizing the weight of gaiters.

In addition, the exercise gaiters of the present invention have the advantage of good shock absorption, so that there is almost no pain at the time of impact, and the strength is improved and the appearance is more beautiful. In addition, since the gaiters are molded in a mold without sewing or adhesive treatment, the adhesive layer is not liberated, thereby improving durability of the product.

In addition, the present invention can minimize the increase in productivity and the production cost by manufacturing exercise gaiters with an automated system, and also has the effect of simplifying the manufacturing process.
