Title: Protector

Description:
BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   This invention relates to a protector. 
   2. Description of the Related Art 
   Conventional protectors have been produced by the following three methods. That is to say, a first protector is made by sandwiching a foamed block body having concavo-convex pattern (composed of polyethylene, polyurethane, ethylene-vinylacetate copolymer, etc.) between a cover and a lining (composed of synthetic leather, etc.) and sewing to form the concavo-convex pattern on the surface (refer to Japanese utility model application No. 7-37655). 
   A second protector is made by sandwiching a board of foamed body (composed of polyethylene, polyurethane, etc.) between a cover and a lining and (cooling or heating) compression molding with a mold as to form a concavo-convex pattern on the surface. 
   A third protector is made by sandwiching a foamed body between a cover, on which a concavo-convex pattern is preliminarily formed by compression molding, and a lining and sewing. 
   And, generally, a protector has shoulder belts and a waist belt wound around a body to put on the protector. And, a buckle male member is attached to each end of the shoulder belts and the waist belt, and buckle female members are attached to a main body side of the protector. Conventionally, the buckle female member is attached to the buckle male member through a belt-shaped attachment member, and disposed on an outer side to a border line of the protector main body. 
   However, in the conventional (three) protectors, convex and concave configurations and patterns on the surface are limited, and complicated configurations and patterns can not be formed on the surface. And, shock absorbability against shocks by speed ball and foul tip by the foamed body is limited. And, the cover may be damaged by spike shoes hitching on the cover when sliding is blocked. 
   And, in the conventional protector, the buckle female member may dangle and hit the body to generate strange feeling on the body, and may be damaged by a ball because the buckle female member is disposed outer to the border line of the main body of the protector when the protector is put on the body. And, a hitching claw portion of the buckle male member, hitching on the buckle female member, may be damaged. Further, damage such as breaking is caused in the belt-shaped attachment member by excessive bending force when the shoulder and waist belts are wound around the body because the belt-shaped attachment member is attached as to be fixed to the main body of the protector. 
   It is therefore an object of the present invention to provide a protector with which desired configurations and patterns can be formed on the surface, shock absorbability is improved, and damage on the surface is prevented, And, it is another object of the present invention to provide a protector with which the damage on the buckle female member and the buckle male member can be certainly prevented.

   DESCRIPTION OF THE PREFERRED EMBODIMENTS 
   Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. 
     FIG. 1  shows an embodiment of a protector relating to the present invention. This protector is provided with a protector main body M having a shoulder portion S and a waist portion W. The protector main body M is composed of a cover  1 , a lining  10 , and a board of foamed body  11  (of polyethylene, polyurethane, etc.) sandwiched by the cover  1  and the lining  10 , sewn with machine sewing thread  9  to be united. The protector is used for umpires and players of sports such as baseball, softball, ice hockey, American football, and put on as to cover a front side of a bust (mainly chest and abdomen). 
   The cover  1  is composed of injection-molded thermoplastic elastomer (TPE) such as of polyurethane system, polyester system, polyethylene system, polystyrene system, etc. 
   The cover  1  has plural convex portions  2  protruding toward a face side, and a bending promotion portion  4  is formed on a groove bottom  3  between neighboring convex portions  2 . The face side means a side opposite to the body. 
   The convex portion  2  has a peripheral wall portion (side wall portion)  13 , a surface wall portion  14 , and an inner space on a reverse side. The groove bottom  3  connects opening ends on the reverse side of the neighboring convex portions  2 . 
     FIG. 2  shows the bending promotion portion  4  formed in a horizontal direction of the protector. The bending promotion portion  4  is composed of a convex small bent portion (small surface-protruding bend  4   a ) on the face side on approximately upper half of the protector, and composed of a convex small bent portion (small reverse-protruding bend  4   b ) on a reverse side on approximately lower half of the protector. 
   The small surface-protruding bend  4   a  is, as shown in  FIG. 3A , composed as to facilitate the bend of the cover  1  in a diminishing direction of the small surface-protruding bend  4   a . That is to say, the cover  1  is freely bent (elastically deformed) as to be convex to the face side in a direction to enlarge the groove. In other words, the cover  1  is hardly deformed in the opposite direction of  FIG. 3A  as to diminish the groove portion because the small protruding bend  4   a  interferes the peripheral wall portions  13 . 
   The small reverse-protruding bend  4   b  is, as shown in  FIG. 3B , composed as to facilitate the bend of the cover  1  in a diminishing direction of the small reverse-protruding bend  4   b . That is to say, the cover  1  is freely bent (elastically deformed) as to be convex to the reverse side in a direction to diminish the groove. 
   Therefore, this protector is, as a whole, even if straight in vertical direction in unworn state as shown in  FIG. 4A , easily bent corresponding to the contour of the body with the upper part bent convex to the face side and the lower part bent convex to the reverse side in wearing state as shown in FIG.  4 B. The bending promotion portion  4  on the groove bottom  3  is omitted in  FIGS. 4A and 4B . 
   And,  FIG. 5  shows the bending promotion portion  4  formed in vertical direction of the protector. The bending promotion portion  4  is composed of a convex small bent portion (small surface-protruding bend  4   a ) on the face side, and the small surface-protruding bend  4   a  is, as shown in  FIG. 6 , composed as to facilitate the bend of the cover  1  in a diminishing direction of the small surface-protruding bend  4   a . That is to say, the cover  1  is freely bent (elastically deformed) as to be convex to the face side in a direction as the groove is enlarged. 
   Therefore, this protector is, as a whole, even if straight in horizontal direction in unworn state as shown in  FIG. 7A , easily bent convex to the face side as to correspond to the contour of the body. The bending promotion portion  4  on the groove bottom  3  is omitted in  FIGS. 7A and 7B . 
   The configuration of the bending promotion portion  4  may be a small protrusion of which cross section is triangle, a configuration composed of plural small bends serially disposed, or any configuration which promotes the bend of the cover  1 . 
   As shown in  FIGS. 2 ,  5 , and  8 , two lines of machine sewing thread  9  sewn to the lining  10  are disposed on both sides of the bending promotion portion  4  (the small surface-protruding bend  4   a  and the small reverse-protruding bend  4   b ) as not to interfere the bending promotion portion  4 . 
   As shown in  FIG. 8 , the bending promotion portion  4  is partially omitted on a crossing portion  5  of the groove bottom  3  as to avoid the machine sewing thread  9 . The crossing portion  5  is a portion on which the groove in vertical direction crosses the groove in horizontal direction, and “partially omitted” means omitted as not to interfere the running of the machine sewing thread  9  in vertical and horizontal directions. And, although a circular deformation promotion portion  4 C is disposed on a position in the crossing portion  5  surrounded by the machine sewing thread  9 , this deformation promotion portion  4 C may be omitted. 
   The above-described convex portion  2 , the groove bottom  3 , and the bending promotion portion  4  are unitedly formed by injection molding. And, as shown in  FIG. 9 , the surface wall portion  14  of the convex portion  2  may be formed preliminarily into a curved face, a concavo-convex face, or an inclined face. And, the surface of the cover may be formed preliminarily into a leather-grain pattern. For example, the thickness of the convex portion  2  is varied on parts as to have a large thickness T 1 , a medium thickness T 2 , and a small thickness T 3 , a groove  12  may be disposed on the convex portion  12 , and the surface of the convex portion  2  may be formed into an inclined face as the thickness of the convex portion  2  gradually decreases downward. Further, as shown in  FIG. 9 , the reverse side of the cover  1  may be preliminarily formed into a concave curved face corresponding to the body. And, although not shown in Figures, the face of the cover  1  may be preliminarily formed into a leather-grain pattern. In short, these configurations and patterns can be easily formed on the cover  1  by forming an injection mold into these configurations and patterns. 
   In the configuration of the convex portion  2  of the cover  1 , not restricted to the embodiments described above, the surface wall portion  14  of the convex portion  2  may be inclined as not to directly receive the shock of such as a ball as shown in FIG.  10 A. And, plural rib portions  16  which contact the foamed body  11  may be disposed in the inner space  15  of the convex portion  2  and on the reverse side of the surface wall portion  14  for shock resistance as shown in FIG.  10 . Further, cushion of the convex portion  2  is soft only with the air layer of the inner space  15  of the convex portion  2  as shown in  FIG. 2 , and the cushion is made hard by the rib portions  16  in the inner space  15  of the convex portion  2 . 
   And, a foamed block body  17  (of polyethylene, polyurethane, ethylene-vinylacetate copolymer, etc.) may be disposed in the inner space  15  of the convex portion  2  as shown in  FIG. 10C , an elastic member  6  may be disposed in the inner space  15  of the convex portion  2  as shown in  FIG. 10D , and, the foamed block body  17  and the elastic member  6  may be disposed in the inner space  15  of the convex portion  2  as shown in  FIG. 10E  to increase degree of freedom of shock resistance. The elastic member  6  is, for example, composed of a spring such as a plate spring and a belleville spring made of injection-molded TPE (thermoplastic elastomer). 
   Further, although not shown in Figures, the rib portions  16  and the foamed block body  17  may be set in the inner space  15  of the convex portion  2 , and the thickness of the surface wall portion  14  of the convex portion  2  may be increased to enhance the shock resistance. 
   Next, as shown in  FIG. 11A , a notched portion  7  for escapement from interference of a mask, having a concave curved configuration, is formed on the convex portion  2  disposed on the shoulder portion S of the protector. The notched portion  7  is formed by injection molding, and the convex portion  2  has no problems in strength and shock resistance for regulation of thickness dimension. The configuration of the notched portion  7  may be an inclined face as shown in FIG.  11 B. Therefore, although a mask and lower parts of the mask currently tend to be large and a throat guard is preferred to wear, the mask (or the throat guard) does not contact the convex portions  2  on the left and right shoulder portions S even if a player shakes his/her head during the game. 
   Next, as shown in  FIG. 12A , radiation holes  8  may be formed through left and right side walls of the peripheral wall portion  13  of the convex portion  2 . The peripheral wall portion  13  is formed by injection molding, and the radiation holes  8  may be formed on upper and lower side walls. And, the peripheral wall portion  13  has no problem in strength and shock resistance. 
   And, as shown in  FIG. 13 , a ventilation pipe  18  is insertedly attached to a position of the lining  10  and the foamed body  11  facing the inner space  15  of the convex portion  2  by sewing with the machine sewing thread  9 . The heat being generated by the body, is radiated from the reverse side of the protector to the face side of the protector through the hole of the ventilation pipe  18  as shown with arrows K, the inner space  15  of the convex portion  2 , and the holes  8  of the convex portion  2 . 
   Although the face side of the protector shown in  FIG. 1  is composed of one cover  1 , the cover  1  may have a block construction as shown in FIG.  14 . That is to say, the cover  1  of the protector is divided into plural parts to make plural divided cover pieces  1   a , and neighboring divided cover pieces  1   a  are sewn with two lines of the machine sewing thread  9  as the bending promotion portions  4  of the cover pieces  1   a  are layered. That is to say, as a finished product, neighboring divided cover pieces  1   a  are layered on the groove bottom  3  between the convex portions  2  and sewn by the machine sewing thread  9  together with the lining  10  and the foamed body  11 . Further, it is desirable to color the divided cover pieces  1   a  with 2 to 6 different colors. 
     FIG. 16  shows another embodiment. A reinforced portion  22  of the cover  1  is composed of injection-molded thermoplastic elastomer, and the cover  1  has plural convex portions  2  protruding to the face side. The reinforced portion  22  is composed of a clavicle portion  23 . In other words, the cover  1  is made as a block construction, and only one divided block or several blocks may be composed of the thermoplastic elastomer. 
     FIG. 17  shows another embodiment. A reinforced portion  22  of the cover  1  is composed of injection-molded thermoplastic elastomer, and the cover  1  has plural convex portions  2  protruding to the face side. The reinforced portion  22  is composed of a dovetail portion  24 . In other words, the cover  1  is made as a block construction, and only one divided block is composed of the thermoplastic elastomer. 
     FIG. 18  shows still another embodiment. A reinforced portion  22  of the cover  1  is composed of injection-molded thermoplastic elastomer, and the cover  1  has plural convex portions  2  protruding to the face side. The reinforced portion  22  is composed of a clavicle portion  23  and a dovetail portion  24 . In other words, the cover  1  is made as a block construction, and only one divided block or several blocks may be composed of the thermoplastic elastomer. 
   The reinforced portion  22  is shown with a solid line in  FIGS. 16  through  18 . Other parts shown with two-dot broken lines have conventional constructions. 
   FIG.  19  and  FIG. 20  show another embodiment. A belt  32  is attached to each of the shoulder portion S and the waist portion W, and the protector main body M is put on the body by winding the belts  32  around the body. 
   The cover  1  has a reverse wall portion  33  and plural convex portions  2  formed on the reverse wall portion  33  and protruding to the face side. The cover  1  has a block construction composed of a base cover  34  which occupies most of the protector main body M and an attached cover  35  attached later to the base cover  34  (by sewing). 
   A buckle male member  31  is attached to an end portion of the belt  32 , and a buckle female member  30 , detachably hitching on the buckle male member  31 , is attached to the protector main body M side. 
   The buckle female member  30  is attached to the cover  1  as to be on an inner side to an border line L of the protector main body M and covered by the convex portion  2 . 
   To describe concretely, the buckle female member  30  is attached to the reverse wall portion  33  of the base cover  34  with a shaft member  36  (such as a caulking pin) as to freely oscillate around an axis  36   a  of the shaft member  36 . And, the buckle female member  30  is covered by the convex portion  2  of the attached cover  35 . 
   Therefore, as shown in  FIG. 21 , the buckle female member  30  does not contact the body and cause strange feelings when the protector is put on the body in use, and the buckle female member  30  is prevented from breaking by contact with a ball, etc. because the buckle female member  30  is disposed on the inner side to the border line L of the protector main body M, covered by the convex portion  2 , and oscillatable around the axis  36   a . Further, the belt  32  wound around the body causes no strange feeling, and the buckle female member  30  is hardly broken without excessive bending force working on parts of the buckle female member  30  because the buckle female member  30  freely changes its direction on the protector main body M side. 
   Further, in a hitching state in which a hitching claw portion  40  (refer to  FIG. 22 ) of the buckle male member  31  is hitched to the buckle female member  30 , the buckle male member  31  (especially, the hitching claw portion  40 ) can be prevented from breaking because the buckle male member  31  is positioned on an inner side to the border line L and the hitching claw portion  40  of the buckle male member  31  is covered by the convex portion  2  along with the buckle female member  30 . And, the buckle male member  31  is hardly broken without excessive bending force working on the buckle male member  31  because the buckle male member  31  can change its direction along with the buckle female member  30 . 
   One (or the both) of the buckle female members  30 , hitching on the buckle male member  31  on the both end portions of the belts  32 , may be fixed. 
   Next, as shown in  FIG. 22 , the buckle male member  31  has two guiding leg portions  37 , a hitching leg portion  38  disposed between the two guiding leg portions  37 , and a belt attachment portion  43  to which the belt  32  is attached and the two guiding leg portions  37  and the hitching leg portion  38  are fixed. 
   The hitching leg portion  38  has a configuration opening toward a forth end side and having at least an upper wall portion  60  and left and right side wall portions  61 . To describe concretely, the hitching leg portion  38  has a concave groove portion  39  opening downward (to the reverse side), and the hitching claw portion  40  is disposed on the concave groove portion  39  as to protrude downward (to the reverse side). That is to say, the hitching claw portion  40  is prevented from breaking because the hitching claw portion  40  is hidden inside the hitching leg portion  38 . 
   The buckle female member  30  has guiding cylinder portions  41  to which the guiding leg portions  37  of the buckle male member  31  are inserted, an elastically-deformable hitching portion  42  fitted into the concave groove portion  39  in the hitching leg portion of the buckle male member  31 , and a base portion  44  to which an end of the elastically-deformable hitching portion  42  and the guiding cylinder portions  41  are fixed. 
   A hitching concave portion  45 , hitched by the hitching claw portion  40  of the hitching leg portion  38 , and a pressed portion  46  to oscillate the elastically-deformable hitching portion  42  in vertical direction (as to be bent), are disposed on the other end of the elastically-deformable hitching portion  42 . And, a hole portion  47 , to which the shaft portion  36  (refer to  FIG. 20 ) is inserted, penetrates the base portion  44 . 
   Next, hitching of the buckle male member  31  to the buckle female member  30  is described. As shown in  FIG. 22 , while the guiding leg portions  37  of the buckle male member  31  are inserted to the guiding cylinder portions  41  of the buckle female member  30  and the hitching leg portion  38  of the buckle male member  31  is fitted to the elastically-deformable hitching portion  42  of the buckle female member  30 , the hitching claw portion  40  of the buckle male member  31  presses and oscillates the elastically-deformable hitching portion  42  of the buckle female member  30  downward as shown in  FIG. 23A , and the buckle male member  31  is hitched on the buckle female member  30  by the hitching claw portion  40  fitting to the hitching concave portion  45  as shown in FIG.  23 B. To describe release of the buckle male member  31  from the buckle female member  30 , as shown in  FIG. 23C , the buckle male member  31  can be released from the buckle female member  30  by pulling off the buckle male member  31  while the pressed portion  46  is pressed downward to oscillate the elastically-deformable hitching portion  42  downward. 
   Next, to describe the attachment of the buckle female member  30  to the protector main body M on the shoulder portion S, first, as shown in  FIG. 24 , the base cover  34  is formed as to have a flat attachment area Z to which the buckle female member  30  is attached, and the attached cover  35  is formed as to have the convex portion  2  having a notched portion  48  for escapement of the buckle as shown in FIG.  25 . 
   And, as shown in  FIG. 20 , the buckle female member  30  is attached on the reverse wall portion  33  (the attachment area Z) of the base cover  34  with the shaft member  36 , and the attached cover  35  is placed on the base cover  34  as to cover the buckle female member  30  with the convex portion  2  from the surface side, then, the buckle female member  30  is attached to the protector main body M by sewing the attached cover  35 , the base cover  34 , the foamed body  11 , and the lining  10  as to be united with a rim-binding portion  25  and the machine sewing thread  9 . 
   As shown in FIG.  20  and  FIG. 25 , the pressed portion  46  can be pressed by pressing an elastically-deformable small convex portion  49  having thin wall, disposed on a part of the convex portion  2  (the surface wall portion  14 ) of the attached cover  35  facing the pressed portion  46  of the buckle female member  30 , from the outside. The buckle male member  31  can be inserted to the buckle female member  30  through the notched portion  48  of the attached cover  35 , and the notched portion  48  does not interfere the oscillation of the buckle female member  30 . 
   Although not shown in Figures, the buckle female member  30  may be covered by another lid member (of polyacetal, etc.). 
   Next, another attached state of the buckle female member  30  to the protector main body M is shown in FIG.  26 . After the buckle female member  30  is attached to the attached cover  35  with the shaft member  36 , the attached cover  35  is sewn with the machine sewing thread  9  from the reverse side of the base cover  34 , and the buckle female member  30  is attached to the protector main body M by sewing the attached cover  35 , the foamed body  11 , and the lining  10  with the rim-binding portion  25  and the machine sewing thread  9 . 
   An operational hole portion  50  penetrates a position on the convex portion  2  (the surface wall portion  14 ) of the base cover  34  facing the pressed portion  46  of the buckle female member  30  as the pressed portion  46  can be pushed from outside. And, a notched portion  48  for escapement of the buckle is disposed on the convex portion  2  of the base cover  34 . 
   Next, another embodiment of the buckle female member  30  and the buckle male member  31  is shown in FIG.  27 . The following construction is clearly different in comparison with FIG.  22 . That is to say, although the hitching claw portion  40  and the hitching concave portion  45  are hitched and released in up-and-down directions (vertical directions) in  FIG. 22 , the hitching claw portion  40  and the hitching concave portion  45  are hitched and released in left-and-right directions (horizontal directions) in FIG.  27 . To describe concretely, the hitching claw portion  40  is disposed in the concave groove  39  of the hitching leg portion  38  as to laterally protrude, the hitching concave portion  45  is formed concave in lateral direction on the elastically-deformable hitching portion  42 , and the pressed portion  46  is constructed as to oscillate the elastically-deformable hitching portion  42  in horizontal direction (as to be bent). The both end portions of the elastically-deformable hitching portion  42  are fixed. 
   And, hitching of the buckle male member  31  to the buckle female member  30  is described. As shown in  FIG. 28A , while the guiding leg portions  37  of the buckle male member  31  are inserted to the guiding cylinder portions  41  of the buckle female member  30  and the hitching leg portion  38  of the buckle male member  31  is fitted to the elastically-deformable hitching portion  42  of the buckle female member  30 , the hitching claw portion  40  of the buckle male member  31  presses and oscillates the elastically-deformable hitching portion  42  of the buckle female member  30  in lateral direction, and the buckle male member  31  is hitched on the buckle female member  30  by the hitching claw portion  40  fitting to the hitching concave portion  45  as shown in FIG.  28 B. On the other hand, as shown in  FIG. 28C , the buckle male member  31  can be released from the buckle female member  30  by pulling off the buckle male member  31  while the pressed portion  46  is pressed in lateral direction to oscillate the elastically-deformable hitching portion  42  in lateral direction. 
   And, buckle female member  30  shown in  FIG. 27  is covered by an oscillation cover member  52  shown in  FIG. 29  for reinforcement. That is to say, as shown in FIG.  29  and  FIG. 30 , the oscillation cover member  52  is a hollow body in which an opening portion  55  for insertion of the buckle female member  30 , a positioning hole  53  to which a positioning protrusion  54  of the buckle female member  30  is fitted, a notched portion  56  to expose the pressed portion  46  of the buckle female member  30 , and a hole portion  47  for insertion of the shaft member  36  (refer to  FIG. 20 ) are formed. 
   Next, to describe attachment of the oscillation cover member  52  including the buckle female member  30  to the protector main body M on the waist portion W, first, as shown in  FIG. 31 , the base cover  34  is formed as to have the flat attachment area Z to which the buckle female member  30  is attached, and the attached cover  35  is formed as to have the convex portion  2  having a notched portion  48  for escapement of the buckle as shown in FIG.  14 . 
   And, as shown in  FIG. 33 , the oscillation cover member  52  including the buckle female member  30  is attached on the base cover  34  with the shaft member  36 , and the attached cover  35  is placed on the base cover  34  as to cover the oscillation cover member  52  with the convex portion  2  from the surface side, then, the oscillation cover member  52  is attached to the protector main body M by sewing the attached cover  35 , the base cover  34 , the foamed body  11 , and the lining  10  as to be united with the rim-binding portion  25  and the machine sewing thread  9 . 
   The buckle female member  30  shown in  FIG. 27  may be covered by a fixation cover member  57  shown in  FIG. 34  instead of the oscillation cover member  52  above. That is to say, as shown in FIG.  34  and  FIG. 35 , the fixation cover member  57  is a through body in which an opening  55  for insertion of the buckle female member  30 , a positioning hole  53  to which a positioning protrusion  54  of the buckle female member  30  is fitted, and a notched portion  56  to expose the pressed portion  46  of the buckle female member  30 , are formed. 
   And, to describe attachment of the fixation cover member  57  including the buckle female member  30  to the protector main body M on the waist portion W, first, as shown in  FIG. 31 , the base cover  34  is formed as to have the flat attachment area Z to which the buckle female member  30  is attached, and the attached cover  35  is formed as to have the convex portion  2  having a notched portion  48  for escapement of the buckle as shown in FIG.  36 . The notched portion  48  of the attached cover  35  is sized only to insert the buckle male member  31  to prevent the fixation cover member  57  (the buckle female member  30 ) from oscillation. 
   And, as shown in  FIG. 37 , the fixation cover member  57  including the buckle female member  30  is sewn on the base cover  34  with the machine sewing thread  9 , and the attached cover  35  is placed on the base cover  34  as to cover the fixation cover member  57  with the convex portion  2  from the surface side, then, the fixation cover member  57  is attached to the protector main body M by sewing the attached cover  35 , the base cover  34 , the foamed body  11 , and the lining  10  as to be united with the rim-binding portion  25  and the machine sewing thread  9 . 
   As shown in  FIG. 38 , a window portion  58  may be formed on the base cover  34  to insert the fixation cover member  57  from the reverse side of the base cover  34  to be sewn to the base cover  34 . 
   Next,  FIG. 39  shows another embodiment of the buckle female member  30 . The following construction is clearly different in comparison with FIG.  27 . That is to say, while the buckle female member  30  in  FIG. 27  bends the elastically-deformable hitching portion  42  by pushing in a direction parallel to the fixation direction of the both ends of the elastically-deformable hitching portion  42 , the buckle female member  30  in  FIG. 39  bends the elastically-deformable hitching portion  42  by pushing in the fixation direction of the both ends of the elastically-deformable hitching portion  42 , so stress by the bend on the fixation portion of the both ends of the elastically-deformable hitching portion  42  can be reduced. 
   Next,  FIG. 40  shows still another embodiment of the buckle female member  30 . The following construction is clearly different in comparison with FIG.  39 . That is to say, while the both ends of the elastically-deformable hitching portion  42  are fixed in the buckle female member  30  in  FIG. 39 , one end of the elastically-deformable hitching portion  42  on the hitching concave portion  45  is an free end in  FIG. 40 , so the elastically-deformable hitching portion  42  can be easily bent. 
   The surface of the cover  1  (namely, the surface wall portion  14  of the convex portion  2 ) may be formed preliminarily into a curved face, a concavo-convex face, or an inclined face, and the reverse side of the cover  1  may be formed as a concave curved face corresponding to the contour of the body. And, the surface of the cover may be formed preliminarily into a leather-grain pattern. In short, these configurations and patterns can be easily formed on the cover  1  by forming an injection mold into these configurations and patterns. 
   In the present invention, not restricted to the embodiments described above, for example, the hitching leg portion  38  of the buckle male member  31  may be cylindrical, and the design of the protector may be changed within the scope of the present invention. 
   According to the protector of the present invention, degree of freedom of the design of the cover  1  is enhanced to easily form desired surface configurations and patterns. And, dimensions such as the thickness of the cover  1  can be freely changed to improve shock absorbability (cushion). And, the cover  1  can be prevented from breaking by spike shoes in sliding or friction with the ground. And, the shock resistance against balls and spike shoes is improved by the convex portion  2 . And, bendability (flexibility) is improved by the bending promotion portion  4  for easy deformation as to correspond to movements of the body for usefulness. And, the convex portion  2 , the groove bottom  3 , and the bending promotion portion  4  can be unitedly formed by injection molding for easy forming and short forming time. 
   Fitting feeling is given to the body because the cover easily bends along with the contour of the body to correspond to movements of both of the upper part and the lower part of the protector. 
   The protector is certainly sewn by the machine sewing thread  9  to be strong and excellent in durability, and bent smoothly as a whole. 
   Running of the machine sewing thread  9  is facilitated for certain and easy sewing. 
   The protector can be easily mass-produced by forming the mold into the surface configurations and patterns of the surface wall portion  14 . And, various designs, hardly expected in conventional protectors, are easily made. 
   The cover  1  can be certainly and easily formed as to give fitting feeling to the body. 
   A luxurious touch can be expressed by the cover  1  of which surface appears to be made of leather or synthetic (artificial) leather. 
   Shock resistance is improved and the degree of freedom for designing elastic force and strength. That is to say, reaction of a ball is decreased by the elastic member  6  and bound of the fallen ball is reduced. 
   The player can play smoothly without strange feelings because the mask does not touch the convex portion  2  even if the player shakes his/her head during the game. 
   The heat of the body can be radiated to the outside to prevent the body temperature from increasing especially in hot weather in summer. 
   Further, new various protectors can be provided with variation of color on each part of the cover  1 . And, strength of the protector is high and the durability is retained. 
   And, according to the protector of the present invention, the degree of freedom for designing the cover  1  is high to easily form the desired surface configurations and patterns. And, thickness of the cover  1  is freely changed to improve shock absorbability (cushion) on parts (areas) where shock absorption is especially required when the ball hits the protector. And, the cover  1  is prevented from breaking caused by sliding spike shoes. And, the shock resistance against the ball, etc. can be improved further by the convex portion  2 . Therefore, the reinforced portion  22  can be principally reinforced to reduce the production cost. 
   The clavicle portion  23  and/or the dovetail portion  24  can be principally reinforced with the reinforced portion  22  of thermoplastic elastomer. 
   The belt  32  wound around the body does not cause strange feelings, and parts such as the buckle female members  30  are hardly broken without excessive bending force because the directions of the buckle female members  30  can be freely changed on the protector main body M side. And, the hitching claw portion  40  can be certainly prevented from breaking. 
   Further, according to the protector of the present invention, the protector can be used without strange feelings because the buckle female members  30  and the buckle male members  31  do not contact the body when the protector is put on the body. And, the buckle female members  30  and the buckle male members  31  can be prevented from breaking by stopping balls against the buckle female members  30  and the buckle male members  31 . Further, the degree of freedom for design of the cover  1  is increased, and the shock resistance of the cover  1  is improved. 
   While preferred embodiments of the present invention have been described in this specification, it is to be understood that the invention is illustrative and not restrictive, because various changes are possible within the spirit and indispensable features.
