Description
The utility model system is ball relevant with motion, more detailed it, mean a kind of a large amount of productions and durable sport ball of being suitable for, belong to exercise.
As shown in Figures 1 and 2, sport ball such as football and vollyball comprises a covering 11 and usually and is located at the interior bladders 12 of covering 11.Covering 11 is made by corium leather or dermatine (as polyurethane PU or polyvinylchloride), as shown in Figure 2, dermatine include altogether in the skin 111, a froth bed 112 and one for strengthen and support in layer 113 within the froth bed 112.12 of bladders are the ball of a sphere, and it is mounted thereto to have a gas tube.
The skin graft body 110 of polylith reservation shape is cut in the corium leather of sheet or dermatine system, wherein for football, prevailing skin graft body 110 is shaped as pentagon and hexagon, easy speech, the covering 11 of football are with staff 12 pentagon skin graft bodies 110 and 20 hexagon skin graft bodies 110 to be stitched together along the edge.In addition, 11 of the spherical coverings of vollyball comprise that the square skin graft body 110 usefulness staff of 18 block lengths are stitched into one along the edge.Inflatable bladders 12 is seated in the covering 11, and the gas tube 121 on the bladders 12 is to extend on covering 11 outer surfaces to locate, and makes the bladders can be by aeration.Air system pours into bladders 12 via gas tube 121, and covering 11 is strutted and reaches the sphere of round shape.So a sport ball that has been full of gas has the characteristics that can bounce, air pours into bladders 12 the more, and the layup of sport ball is stronger.
The hardness that known as mentioned above various motions are ball and can anti-degree all be the structure that is decided by covering 11, and irrelevant with the soft rubber bladders in the covering 11 12.The structure of covering 11 must be fastened to is enough to relax the impulsive force that all form when playing ball.So, be that corium leather or the made skin graft body 110 of dermatine all can affix to less the two-layer reinforcement internal layer 114,115 that is made of coarse cloth, to strengthen supportive and anti-stress to covering 11.So move ball circularity and reinforcement degree are to rely on the cloth intensity of reinforcement internal layer and decide entirely.Therefore, select good reinforcement inner layer cloth just to seem and particular importance also can increase the material cost of known sport ball.The reinforcement internal layer the 114, the 115th that adds, sticking on the bottom surface of the internal layer 113 of dermatine or directly stick earlier on the leather substance bottom surface of the skin graft body 110 that be not cut in layer is so increased the manufacture process of binding together.Moreover the reinforcement internal layer 114,115 that adds has not only increased the thickness of covering 11, has also increased the hardness of covering 11 simultaneously.This thick and hard skin graft body 110 has also increased the difficulty that sewing machine is stitched together each skin graft body 110, especially when sewing up the skin graft body arm of angle, just be the position of covering 11 most fragiles, thus need the appropriate tough skill of making, so the motion of most famous brand is ball all to make by hand.The sewer must a pin one pin ground be stitched together each skin graft body 110, and a sewer who is skilled in technique can only make two sport balls usually in one day.This kind practice is time-consuming, and cost improves a lot.In addition make ball the remaining of motion by hand in another big shortcoming, that is exactly that the sewer can't can both sew up with identical power by every pin.So behind inflating sports ball, covering 11 will be shored outside expansion by bladders 12, the position of failing closely to sew up will influence the circularity of ball because of unbalance stress.In addition, suture also need adopt thick tough first-class sewing thread, and to avoid having the possibility of broken string when playing ball collision, particularly the suture ratio at that more weak position is easier to fracture.
