摘要： PROBLEM TO BE SOLVED: To provide a stud for sports shoes, which is not easily dropped from a sole in the case of walk or play, concerning a mashroom-shaped stud to be used suitably for sports shoes such as golf shoes, especially, for so-called soft spike shoes. SOLUTION: This stud for sports shoes is attached onto the sole by connecting bolt parts to a central part on the upper surface of plate-shaped main body 4 of stud and screwing the bolt parts into nut parts arranged on the sole. In that case, on the lower surface of main body 4 of stud, a ridge 2 is projected out while being extended from inside to outside and at the top end of ridge 2, a section 6 is formed while being inclined downward from outside to inside. Further, when the ridge 2 is grounded and load is applied to the section 6 inclining its top end downward, a rotating force in the same direction as the rotating direction of main body of stud at the time of attachment to the sole is applied to the main body 4 of stud.

摘要： PROBLEM TO BE SOLVED: To show an effect by means of pins provided in rivets on the soft ground and to walk with cushion property where the softness of rubber is utilized on a hard road surface by providing rivet units having rubber points in the periphery of the rivets where the pins are projected in a tip part in the heel part and the stamping part of a sole. SOLUTION: One pair of rivet units 21 are respectively arranged at the inner side I and the outer side O of the sole 1 in the heel part 2 of the sole 1 by deviating the outer side O to be a little closed to the tip 6 of the sole 1 and the inner side I to be closed to a rear end 7. The two pairs of rivet units 21 are arranged at the inner side 1 of the stamping part 4 by deviating them a little in a direction opposite to the heal part 2. The plural rubber points 20 which are substantially the same as the ones used in the rivet units 21 are arranged in the remaining area of the sole 1 with a prescribed interval. A solid rivet is provided with structure where the pin and a rivet mainbody are integrated and the shape of the pin is desirable to be the cylindrical one. The rivet mainbody is directly embedded and fixed to the sole 1 or screwed and fixed through the use of a screw means.

摘要： PROBLEM TO BE SOLVED: To provide a racket frame which can be manipulated easily even for a high-level player having high swing speed, has high repulsiveness against high speed, further, easily loads spin and improves controllability as well. SOLUTION: Concerning a racket frame 1 made of fiber reinforced synthetic resin having a face part 2 forming a gut face by spreading over gut, shaft part 3 continued to the face part 2 and grip part 4 continued to the shaft part 3, when the weight is less than 260g and measured while fixing the base end of the grip part 4 and applying the load of 6kg to the top end of the racket frame vertically to the gut face, the bending warp quantity of the racket frame 1 is less than 11mm. When the load of 6kg is applied to the widest section of the face part 2 vertically to the gut face, a torsion angle around a frame axis is smaller than 2 deg., S/T is from 0.3 to 0.6 and T is less than 22mm.

摘要： PROBLEM TO BE SOLVED: To increase flexibility and to improve a gripping property by forming dents in the bottoms of the positions proximate to the toe parts of shoe soles, thereby forming the bottoms thin. SOLUTION: The dent 2 of the shoe sole 1 exists in the bottom 4 where the body weights usually acts most exclusive of a heel part 3 and particularly in the central area of the bottom 4. The dent 2 preferably exists only at the bottom 4 and may also exist near to the heel part 3. The depth of the dent is so determined as to increase gradually from the boundary between the edges 5, 6 toward the center. The dent 2 is so formed as to have the depth gradually increased toward the center in a vertical direction (longitudinal direction) as well. Then, the shape of the dent 2 is domes as a whole. The maximum depth (b) of the dent 2 is confined within a range of 20 to 50% of the thickness (c) of the sole of the part. The width (v) of the dent 2 is confined within a range of 25 to 50% of the width (w) over the entire part of the shoe sole 1. The position thereof is so determined as to substantially exist at the center from the bottom 4.

摘要： PROBLEM TO BE SOLVED: To improve bending rigidity and strength and to improve the walking quality of shoes by forming the cross sections of shanks to an arch shape. SOLUTION: The shank 2 is arranged around an arch area 4 in a longitudinal direction and is arranged from the front end of a heel 5 toward the rear end of a treading bottom 6. The shank is arranged in the central part of the area in a transverse direction. The shape of the shank 2 is formed to an arch shape in the shape of its cross section and is straight in the longitudinal direction. In some cases, the shape in the longitudinal direction section is formed to the arch shape as well. Thermosetting resins reinforced by compounding fibers, such as carbon fibers, aramid fibers and glass fibers, therewith, metals, such as aluminum, and others are used for the material of the shank. These materials are used by laminating the materials or mixing the materials with another materials.

摘要： PROBLEM TO BE SOLVED: To improve the durability of a shoe sole by integrally compounding an abrasion resistant base material in a certain part on the shoe sole. SOLUTION: In this shoe sole, an abrasion resistant base material is compounded at a part requiring abrasion resistance. The abrasion resistant base material is set on a prescribed position in a mold for forming the shoe sole and rubber material is poured into the mold to be compounded integrally. In another case, a dent is formed on a prescribed position and the abrasion resistant material is inserted and fixed in the dent when the shoe sole is formed with rubber base material. The abrasion resistant base material A to be used for the shoe sole consists of a netted metallic wire 1 and a SBR rubber 2 surrounded by the wire 1. The base 4 of the shoe sole is made of SBR rubber, and the abrasion resistant base material A is buried and compounded in the shoe sole base 4 in the lower part of the outer circumference of the toe part 5 of the shoe sole base 4.
