Abstract

一种高弹力软式排球,是由可发泡树脂材料制成的海绵状实心球体,比较传统排球重量较轻、球速较低、手感柔软,有良好的飘风能力,是普及排球运动的适宜用球,尤其适合老年人和少年儿童使用。

Description

一种高弹力软式排球
排球运动是受人们喜爱的一种运动项目,参加人数很多,传统的排球采用皮革制造,内装球胆,比较重,手感硬,初学者容易伤手指。后来日本国发明了一种所谓软式排球,采用橡胶制造,手感软一些。上述两种球都为中空充气球。而对于老年人和少年儿童参加排球运动,上述两种球都存在重量大、手感硬、球速太快等问题。近来,出现了一种称叫气排球的运动,选用的球是近似于气球的充气球,却又显得太轻,存在飘风能力差、速度太慢等缺点。
本实用新型针对上述排球性能上存在的不足,设计一种重量、球速、手感、飘风能力皆适宜的高弹力软式排球。可满足排球运动普及的需要,尤其适合老年人和少年儿童使用。
本实用新型可通过以下措施来实现。
采用高分子可发泡树脂,在模具的型腔中成型,或者采用将发泡成型的坯料,利用旋风切削的方法切削成型,制成直径为15-30厘米,重量为100-300克的实心球体,该球的断面为海绵状结构,其表面覆盖着一层致密的薄膜(模塑成型)或表面无膜(切削成型)。
以下通过附图作详细说明。
附图是含有局部剖视的立体图形。从图中可以看出:球体1由海绵体3和覆盖在表面的薄膜2构成。
下面通过最佳实施例作进一步说明:
实施例1:采用聚氨脂树脂,加入发泡剂、稳定剂等助剂,混合均匀后注入模具型腔,加热成型,脱模后即得直径为20厘米,重量约为200克的实心海绵状球体1,球表面覆盖着一层致密的薄膜2。
实施例2:采用聚氨脂树脂发泡成型制得坯料,在专用的铣床上采用旋风铣切刀具,切削成型,制得直径为24厘米,重量为280克的实心海绵状球体1,表面无膜。
采用本实用新型技术制造的高弹力软式排球的积极效果在于:该球为开展群众性排球运动提供了适宜用球。这种软式排球,比较传统的排球,重量较轻,速度较慢,手感柔软,而比较气排球,则有飘风能力好,空中运行稳定的优点。尤其适宜中老年人和少年儿童使用。
