Abstract: A customizable training bat includes a handle on a proximal end and an endcap on a distal end. Several body segments used for hitting extend between the handle and the endcap from the proximal end to the distal end over an extendable support rod passing through each of the body segments. To prevent relative shifting and movement between handle and body segments or between adjacent body segments, handle and body segments may contain mechanisms for interlocking. An optional hollow casing encloses the body segments and is connected to the handle in a way that allows it to be extended. The handle also optionally has a detachable knob of variable weight. The length of the bat is varied by adding or removing the body segments and adjusting length of support rod extending from the handle. The bat's size, shape and swing weight can be modified by using the desired body segments.

Abstract: A customizable training bat comprising a handle on a proximal end, an endcap on a distal end, a plurality of body segments used for hitting balls extending between the handle and the endcap from the proximal end to the distal end over an extendable support rod, wherein said the extendable support rod is passed through each of the plurality of body segments. Body segments may have provisions for interlocking to avoid shifting in between adjacent body segments, or between handle and body segments. An optional hollow casing that encloses the body segments and connects with the handle in manner that makes it extendable, provides a hitting surface. Further, the handle has an opening for accommodating the extendable support rod and the casing. The handle also optionally has detachable knob of variable weight. The length, shape, thickness, swing weight and size of the training bat may be customized according to preferences of an athlete.
