Abstract
A bat used for baseball or softball includes a bat body including a grip part, a taper part and a first tube, a fixing component including a first fixing component and a second fixing component and a cylindrical second tube having two opened ends, the inner diameter of the cylindrical second tube being larger than the diameter of the first tube, the second tube being placed on the outer circumference of the first tube and being latched so that a gap is formed between the bat body and the second tube via the first fixing component and the second fixing component.
Claims18
A bat used for baseball or softball comprising;
- a bat body including a grip part, a taper part and a first tube and having at least one or more interlocking grooves;
- a cylindrical second tube having two ends, the inner diameter of said cylindrical second tube being larger than the diameter of said first tube of said bat body, said second tube is placed on the outer circumference of said first tube of said bat body;
- and
- a fixing component including a first fixing component and a second fixing component which latches said second tube to said bat body so that a gap from 0.1 mm to 3.0 mm is formed between said second tube and said bat body so that said second tube bends inwards and contacts with said first tube when a ball is hit, said fixing component performing the role of a support point when said second tube bends inwards when a ball is hit, wherein said at least one or more interlocking grooves interlock with said fixing component and one of said interlocking grooves is formed at a predetermined position close to an end of an outer surface side of said bat body.
A bat used for baseball or softball comprising:
- a bat body including a grip part, a taper part and a first tube;
- a fixing component including a first fixing component, a second fixing component and a third fixing component and having at least one or more interlocking grooves;
- and
- a plurality of cylindrical second tubes each having two open ends, the inner diameters of said plurality of cylindrical second tubes being larger than the diameter of said first tube of said bat body;
- at least one of said plurality of cylindrical second tubes being formed from a different material to those of the other cylindrical second tubes, said plurality of cylindrical second tubes being placed on the outer circumference of said first tube of said bat body and being latched so that gaps are formed between said bat body and said plurality of cylindrical second tubes via said first fixing component, said second fixing component and said third fixing component, wherein said bat body has at least one or more interlocking grooves which interlock with said fixing component and one of said interlocking grooves is formed at a predetermined position close to an end of an outer surface side of said bat body.
