The volume of Association football, basketball or vollyball and surface area can calculate according to the general equation that is used for spheroid:
Surface area=4 π r 2
Wherein r is a radius.
The volume of rugby and surface area can calculate according to the general equation that is used for prolate sphere:
Figure A20081016780100102
Figure A20081016780100103
Wherein a is the radius of minor axis, and b is the radius of major axis, and e = cos - 1 ( a b ) . Minor axis radius is half of minor axis length, and major axis radius is long axis length half.Though rugby not exclusively is the shape of prolate sphere also, difference is not remarkable.
The ball for sports that satisfies various demands of the present invention is particularly suitable for young child.The easier manipulation of this ball for sports, have the weight of minimizing and also reduce the risk be hurt.And this ball for sports generally can also satisfy the dimensional requirement (being girth, length) of above-mentioned all size.
Ball for sports of the present invention is generally made according to methods known in the art.Yet, some difference is obviously arranged.Cladding material will be thinner.Winding layer (winding layer) can be thinner.The material that weight is lighter or density is littler can be used for the inside of ball for sports or is used as cladding material.Capsule and ball tire raw material (carcass stock) also can be thinner.The gas that can also use density to be lower than air is inflated to ball.
Ball for sports is generally made by having tectal ball tire in the above, and cover layer is formed by the cover plate that is attached to ball tire outer surface.The outer surface of ball tire also can have from its outstanding burr (rib) to define seam on the basketball for example or some parts of groove.Ball tire itself can be by inflatable capsule, winding layer and some intermediate layers that may be intended to strengthen or reduce the various performances of ball for sports form.
Cover plate generally has from 0.5 millimeter to 3 millimeters thickness.Capsule generally has from 0.5 millimeter to 3 millimeters thickness.Winding layer generally has from 0.5 millimeter to 3 millimeters thickness.The intermediate layer can have from 0.5 millimeter to 3 millimeters thickness.Therefore the ball mold has the thickness (concerning this measurement, burr not being considered as the part of ball tire) from 0.8 millimeter to 5.2 millimeters.
Ball for sports of the present invention can have thinner ball tire, to such an extent as to the ratio of overburden cover and ball tire thickness is 4.0 or bigger.In other embodiments, overburden cover is from 4.0 to about 6.0 with the ratio of ball tire thickness.
The embodiment of reference example has been described ball for sports of the present invention and method.Obviously, in case read and understand the detailed description of front, other people just will expect modifications and changes.Wish that exemplary embodiment is interpreted as the modifications and changes that comprise that all are such, such modifications and changes are included in the scope of appended claims or its equivalent simultaneously.
