Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement in the manufacturing method of supporters used in volleyball and other various sports.

(Prior Art) Conventionally, various types of supports have been used as supports to be attached to the knees or 1I=I in various sports.

Various manufacturing methods have been proposed in order to effectively demonstrate its functions, and one example is the
No. 39910 can be mentioned.

As shown in Fig. 6, this manufacturing method involves forming the front surface into a bowl shape by hot pressing, providing four portions 20 in the center of the back surface that are slightly recessed toward the front surface, and forming the peripheral portion to be thin. It is also made of an approximately elliptical elastic body with an appropriate thickness and having one or more horizontally extending four-striped grooves 21 on its surface. P, +422, the bowl-shaped portion on the surface of the core material 22, and the surface having the grooves 23 facing in the horizontal direction of 1 qJ ten each, and the cover 24 is formed by hot pressing so that the entire shape is approximately the same. The cover 24 is fitted to the surface of the core +A' 22 to cover it, and the two are joined at the edge 25 to form a pad body 26.
The peripheral edges 25 of the buffs 1 to 26 can be placed at predetermined positions on the outer surface of the lunar phase supporter body 27.

(Problems to be Solved by the Invention) Regarding the above conventional example, 1. In the manufacturing method thereof, the core material 22 and the cover 24 are each formed by hot pressing as the final shape of the tJ pad body 26, so the required Two molds of male and female silk are required, and a core material 22 and a cover 24 are required.
One mold for polymerizing and bonding is required for male and female navy blue, and temporarily one puff is required.
If the integral parts 26 are to be produced in different shapes, such as sizes, etc., a dedicated mold is required for each, and the manufacturing cost is high.

Moreover, according to this method, the core material 22 and the cover 24 are formed separately using press molds, and there is a problem in that it requires about 1 or more steps of polymerization and bonding.

First, the pad body 26 manufactured by this method has the core material 2
Since one or more horizontal grooves 2L23 are formed over the surface of the cover 2 and the cover 24, when the No. The upper part of groove 2+ and 23 is the border! , I↓It is easy to bend 1~ on the curved side, but the 6th
As is clear from the figure, although there is a four-striped groove 2L23, the core member 22 is connected internally and is a body, so for example, when jφ1 hits 7 from the diagonal horn direction, the core member 22 undergoes spring deformation. However, there is a drawback in that there is no sufficient absorption of the impact horns by the impact part JJI.

(Means for Solving the Problems) In order to solve the problems described in 1-4 of the present invention ε,
This is a new and improved manufacturing method for J-Porter. A core material (4) formed into a shape plate (4) and a cover material (2) such as a non-woven fabric formed by heating press so as to have a hook shape of a size that completely covers the surface of the core material (4) are set. (2), the cover material is polymerized with the core material layer 4 through the adhesive, and the core material, adhesive layer and It is a polymeric integral body consisting of a cover, and the center part is thick and the wall becomes thinner as it reaches the peripheral edge, and there are 1-1 wood grooves and 1-2 grooves extending in the lateral direction on the outside of both the front and back surfaces, and the peripheral edge. A plurality of inverted bowl-shaped pads are obtained, and the h1 edge of the pads is placed at an appropriate position on the outer surface of the knee or elbow supporter body.

(Example) An example of the present invention will be described with reference to FIGS. 1 to 5. 1st
The figure is a perspective view of the external appearance of a pad body manufactured by the method of the present invention, and Figure 2 is a cross-sectional view taken along the line A-A in Figure 1. A core body 2- made of an elastic body covers the entire surface of the core material 1 with an adhesive layer 3 in between. Reference numeral 4 denotes an elliptical bowl-shaped pad body 4 in which the core material 1, adhesive layer 3, and cover 2 are polymerized, and the wall thickness is greatest at the central portion and becomes thinner toward the periphery. In addition, one or more concave grooves 5, 5 facing in the lateral direction are provided at positions corresponding to both the front and back sides, and three pad areas are separated by the four grooves 5.5 and the peripheral edge 6 in the independent illustration. Fields 4a, 4b, and 4c are formed. Although the pad body 4 is not shown,
The peripheral edge 6 is placed at an appropriate position on the outer surface of the Zapota main body 27, which is a stretchable cylindrical body made of conventionally known rubber woven fabric or the like.
If you arrive at T, etc., you will receive a 1 digit.

Next, a method for manufacturing the pad body 4 will be explained with reference to FIG. The core material 1, which is the core material 1, is a block formed into a flat corner t (one trapezoid shape) by cutting a plate of porous foamed elastic material such as urethane foam 1. 2
The cover material 2 is made of non-woven fabric, woven fabric, knitted fabric, etc., preferably made of abrasion-resistant fibers of appropriate thickness, and this is pressed into the core using a hot press 7 as shown in FIG. Use an oval hook shape large enough to completely cover 1° above the material. The heating press 7 includes a ring-shaped female mold 8, a male mold 9 with a hemispherical tip that protrudes into the ring of the female mold 8, and a male mold 9 that surrounds the male mold 9 and is attached to the base body 9 of the male mold 9 so as to be movable forward and backward. The fabric 11 is placed on the female die 8, and the male die 9 is pressed down toward the die 8 to first fix the periphery of the fabric 11 with the press ring 10, and then An elliptical bowl-shaped cover material 2゛ is obtained from the hemispherical part of the mold 9. Note that the mold 9 has a circular shape 4), L
:<The shape is not limited.

A pot-melt film, which will later become the adhesive layer 3, is further polymerized on the surface of the core material +41' obtained in this manner, and a cover layer of 2゛ is then molded using a hot press mold 12 shown in Fig. 5. By doing so, we obtain the desired Pano I/Body 4. At this time, the above hot press mold 12
and a female mold 12", and grooves/#5 running in the horizontal direction are provided at corresponding positions on both the front and back sides of the pad body 4, at corresponding positions on the ten faces of the male mold 12" and the lower surface of the female mold 12". The protruding strips 13.13 to be formed and the uneven strips 14.14 forming the peripheral edge 6
' is formed.

In the illustrated embodiment, the protruding strip 13. Since 13 was provided in two places, according to the mold shown in -, there are three pad sections 4a.

4b, 4C can be formed. In addition, since the hot press mold 12 is heated to an appropriate temperature, when pressed, the hot melt film 3° melts and the cover 2 and core)
41 is firmly adhered and solidified to form the adhesive layer 3. The pad body 4 thus obtained has excess fabric remaining on its peripheral edge 6, and the taut portion is punched out using a cutting die to obtain a shaped pad body 4 as shown in FIG. 1.

Although the embodiments of the present invention are as described above, the adhesive layer 3 may be formed using a hot melt film or other adhesives may be used. Of course, it is not limited to the illustrated example, but the cover material 2° of this example
