摘要： A drumstick structure provides a structural outer body, preferably transparent, with a central hollow bore therein, into which a rod can be inserted as desired. The central portion is permanent, or removable which can be interchanged between drumsticks as desired. In the preferred embodiment, the inner portion is comprised of an elongated shaft which conforms to the configuration of the inner bore. An end cap seals off the inner bore securing the rod therein by providing a screw-on end portion. In the preferred embodiment the cap can be an enlarged rubberized tip to provide a tympani beater head. In an alternative embodiment, the inner portion is injected with an injection moldable plastic, the plastic then hardened to form a permanent but lighter inner portion so as to make the overall drumstick a desired weight. The drumstick would be of a plastic construction to provide greater strength. In the preferred embodiment, the outer portion would be clear so that the inner portion would be visible to an observer through the outer clear structure. Thus, an individual could swap inner portions to provide a desired color as the individual may prefer. A gum rubber band can be placed on the outer surface of a portion of the drumstick as an aid to gripping and can also be permanent or removable. In another alternative embodiment, an end tip cap seals off the inner bore from the front securing the rod therein by providing a screw-on tip portion.
摘要翻译：鼓槌结构提供结构外体，优选是透明的，其中具有中心空心孔，根据需要可将杆插入其中。中心部分是永久的或可拆卸的，可根据需要在鼓槌之间互换。在优选实施例中，内部部分由符合内孔构造的细长轴构成。端盖通过提供螺旋的端部部分来密封固定杆的内孔。在优选实施例中，盖可以是扩大的橡胶头以提供鼓鼓打击头。在一个替代实施例中，内部部分注射可注塑模塑料，然后将塑料硬化以形成永久但较轻的内部部分，以使整个鼓槌具有所需的重量。鼓槌将是塑料结构，以提供更大的强度。在优选实施例中，外部部分将是透明的，使得内部部分将通过外部透明结构对观察者可见。因此，个人可以互换内部部分以提供期望的颜色，因为个人可能喜欢。橡胶胶带可以放置在鼓槌的一部分的外表面上，作为夹持的帮助，并且也可以是永久的或可移除的。在另一替代实施例中，端尖帽通过提供螺旋式尖端部分将内孔与前部密封，从而将杆固定在其中。
