Description

  The present invention relates to a protector.

  Conventional protectors include protectors manufactured by the following three methods. That is, the first protector sews a foamed block body having unevenness (made of PE, PU, EVA, etc.) between a front fabric and a back fabric (made of synthetic leather, etc.) sandwiched in a sandwich shape. The surface was uneven and formed on the surface. (For example, see Patent Document 1 below.)

  The second protector has a plate-like foam (such as PE or PU) sandwiched between a front fabric and a back fabric in a sandwich shape, and an uneven shape is formed on the surface by compression molding (cooling or heating) using a mold. It was made to be.

  The third protector was manufactured by compressing and molding only the front fabric to form an uneven shape, and then sewing the sandwich between the front fabric and the back fabric in a sandwich shape.

  However, with the conventional (three) protectors, there are limits to the irregularities desired for the surface shape and pattern, and complex shapes and patterns could not be formed on the surface. Further, there was a limit to the impact absorption in the thickness of the foam with respect to the impact of the speed ball, foul chip and the like. In addition, there is a risk that the surface may be damaged due to a spike being caught during the sliding block.

  Therefore, an object of the present invention is to provide a protector that can form a desired shape / pattern on the surface, has improved shock absorption, and prevents damage to the surface.

In order to achieve the above-mentioned object, the protector according to the present invention has a skin made of an injection-molded thermoplastic elastomer having a plurality of protruding portions protruding on the front side, and a plate-like foam and a back side on the back side. The dough is provided in an overlapping manner, and the ridge has an internal space on the back side, and a heat radiating hole is provided in the peripheral wall of the ridge , and the ridge of the site of the plate-like foam and fabric back facing the interior space, through the plate-like foam and fabric back, with a hole portion communicating from the protector back surface side to the internal space.

The present invention has the following remarkable effects.
According to the protector according to the present invention, the degree of freedom in designing the skin increases, and a desired surface shape / pattern can be easily formed. In addition, the thickness of the epidermis can be freely changed, and the shock absorption (cushioning property) is improved. Further, it is possible to prevent the skin from being damaged due to the hooking of the sliding spike. Furthermore, the impact resistance against the ball or the like is further improved by the protruding portion. Further, the heat of the body can be released to the outside, and in particular, an increase in body temperature can be prevented during play under hot weather such as in summer.

Hereinafter, the present invention will be described in detail with reference to the drawings illustrating embodiments.
1, 2, and 5 show the basic structure of the protector according to the present invention, which is sandwiched between the skin 1, the back fabric 10, and the skin 1 and the back fabric 10. The skin 1, the foam 11, and the back fabric 10 are sewn together with a sewing thread 9. This protector is used for referees and players in sports such as baseball, softball, ice hockey, and football, and is used by covering the upper body (mainly on the chest and belly) with a covering. The

  The skin 1 is made of an injection molded thermoplastic elastomer (TPE), and examples of the TPE include polyurethane, polyester, polyethylene, and polystyrene.

  The skin 1 has a plurality of protruding ridges 2 protruding to the front side, and a bending deformation assisting portion 4 is formed on the groove bottom 3 between the adjacent protruding ridges 2 and 2. The front side means the side opposite to the body.

  The protruding portion 2 has a peripheral wall portion (side wall portion) 13 and a surface wall portion 14, and has an internal space 15 on the back surface side. The groove bottom 3 is connected to the open side edges of the adjacent protruding ridges 2, 2.

  FIG. 2 shows a bending deformation facilitating portion 4 that runs in the left-right direction. The bending deformation facilitating portion 4 in the upper half of the protector is configured with a convex small curving portion (front projecting small curving portion 4a) on the front side. The bent deformation assisting portion 4 in the substantially lower half of the protector is configured with a convex small bent portion (back protruding small bent portion 4b) on the back side.

  As shown in FIG. 3 (a), the front protruding small bent portion 4a is configured to facilitate bending of the skin 1 in the direction in which the front protruding small bent portion 4a is reduced in diameter, that is, the groove portion is enlarged. In the direction, the skin 1 can be bent and deformed (elastically deformed) in a convex shape on the front side. In other words, if the groove portion is to be deformed in the direction opposite to that in FIG. 3, the front protruding small bend portion 4 a interferes with the peripheral wall portions 13 and 13 and is not easily deformed.

  As shown in FIG. 3 (b), the back protruding small bent portion 4b is configured to facilitate the bending of the skin 1 in the direction in which the back protruding small bent portion 4b is reduced in diameter, that is, the groove portion is reduced. The skin 1 can be bent and deformed (elastically deformed) in a convex manner on the back side in the direction.

  Therefore, as shown in FIG. 4 (a), the protector as a whole is not attached to the body, even if it is straight in the vertical direction, as shown in FIG. In the wearing state, in accordance with the curved shape of the body, the upper part is convexly deformed to the front side, and the lower part is convexly deformed to the back side. In FIG. 4, the bending deformation assisting portion 4 of the groove bottom 3 is omitted.

  Further, FIG. 5 shows a bending deformation assisting portion 4 that runs in the vertical direction. The bending deformation assisting portion 4 is configured with a convex small bending portion (front protruding small bending portion 4a) on the front side. As shown in FIG. 6, the small bend portion 4 a is configured to facilitate bending of the skin 1 in the direction in which the surface protruding small bend portion 4 a is reduced in diameter, that is, the groove portion is enlarged and the skin 1 is formed. It can be bent (elastically deformed) in a convex manner on the front side.

  Therefore, as shown in FIG. 7 (a), the protector as a whole is not attached to the body, even if it is straight in the left-right direction, as shown in FIG. In the wearing state, it is easily bent into a convex shape corresponding to the curved shape of the body. In FIG. 7, the bending deformation assisting portion 4 of the groove bottom 3 is omitted.

  In addition, the shape of the bending deformation assisting portion 4 may be a small protrusion having a triangular triangular cross section, or may be a shape in which a plurality of small bending portions are connected in a waveform, and the skin 1 is bent. Any shape may be used as long as it is easy to shape.

  As shown in FIGS. 2, 5, and 8, on the both sides of the bending deformation assisting portion 4 (the front protruding small bending portion 4 a and the back protruding small bending portion 4 b), the back fabric is prevented from interfering with the bending deformation promoting portion 4. Two sewing threads 9, 9 to be sewn on 10 are arranged.

  As shown in FIG. 8, the bending deformation facilitating portion 4 is partially omitted from the cross intersection 5 of the groove bottom 3 so as to avoid the sewing thread 9. Here, the cross intersection 5 is a portion where the upper and lower grooves and the left and right grooves intersect with each other in a cross, and partially omitted is omitted so as not to interfere with the vertical and horizontal running of the sewing thread 9. It means being done. In addition, although the circular deformation | transformation assistance part 4c is arrange | positioned in the site | part enclosed by the sewing thread | yarn 9 of the cross | intersection part 5, it is also free to abbreviate | omit this deformation | transformation assistance part 4c.

Here, the protruding portion 2, the groove bottom 3, and the bending deformation assisting portion 4 described above are integrally formed by injection molding. Further, as shown in FIG. 9, the surface wall portion 14 of the ridge 2 may be formed in advance as a curved surface, an uneven pattern surface, or a gradient surface. For example, the ridge 2 The thickness of the ridge 2 is changed to a large thickness T ₁ , a middle thickness T ₂ , a small thickness T ₃ , or a groove 12 is provided in the ridge 2. It is good also as a slope surface so that the thickness of the protruding part 2 may decrease gradually below. Furthermore, as shown in FIG. 9, you may shape | mold the back surface side of the epidermis 1 beforehand as the concave curved surface shape corresponding to a body. Although not shown, the surface of the skin 1 may be formed in advance as a leather pattern. In short, the shape / pattern can be formed on the skin 1 by forming the shape / pattern on the injection mold.

  Next, as shown in FIG. 10 (a), a concavely curved mask interference escape notch portion 7 is formed in the protruding portion 2 disposed in the shoulder portion S of the protector. Of course, the notch portion 7 is formed by injection molding, and the strength surface and the impact-resistant surface of the ridge portion 2 have no problem by adjusting the thickness of the ridge portion 2 and the like. Note that the shape of the notch 7 may be an inclined surface as shown in FIG. Accordingly, recently, the mask and the lower part of the mask tend to be larger and the throat guard tends to be worn. However, even when the head is swung left and right during play, the mask is applied to the ridges 2 of the left and right shoulder portions S, S (Or throat guard) does not come into contact.

  As shown in FIG. 11 (a) showing the specific configuration of the present invention, the heat radiating hole 8 may be provided through the left and right side walls of the peripheral wall portion 13 of the protruding portion 2. Of course, the peripheral wall portion 13 may be formed by injection molding and provided at the position of the upper and lower side walls as shown in FIG. Moreover, since it is formed by TPE, there is no problem in terms of strength and impact resistance.

  Then, as shown in FIG. 12, a ventilation pipe 18 is attached with a sewing thread 19 in a penetrating manner to the portion of the back fabric 10 and the foam 11 that oppose the internal space 15 of the ridge 2, and heat generated from the body.
