A bat, which has a hollow barrel and an internal assembly configured to resist deformation of the hollow barrel, is disclosed. The internal assembly includes multiple rods disposed longitudinally within the hollow barrel. The internal assembly can include a deformable ring having a substantially circular outer wall having a diameter less than an inner diameter of the hollow barrel and multiple holes, with each hole configured to at least partially receive a rod of the multiple rods. The bat can have an end cap including end cap holes extending partially through the end cap, with each end cap hole configured to at least partially receive a rod.

A putter type golf club includes a putter head with a ball striking face, a shaft attached to said putter head, and an elongated grip attached to the shaft. The elongated grip includes a lower section, an upper section and a cap forming a butt section at the upper area of the grip, the lower section of the elongated grip including a shaft opening at a lower end thereof, the lower section of the elongated grip structured to accommodate the hands of a golfer, the upper section of the elongated grip having a leading edge located in a direction toward and closest to an intended target with the putter head in a normal position prior to executing a normal putting stroke.

Golf club shaft assemblies with removable counterbalance weights are disclosed herein. In each embodiment, a shaft sleeve is secured within a butt end of a shaft and a weight is removably affixed to the shaft sleeve via locking structures, magnets, and/or spring devices.

A golf club shaft includes a shaft body having a butt end and a tip end, and a counterweight member on an outer periphery of the shaft body between the butt and tip ends. The counterweight member is made of a fiber composite material configured in a way that the counterweight member has a color visually distinguishable from that of the shaft body.

A racquet including a tubular frame formed of a fiber composite material, a pallet and a butt cap. The frame includes first and second end regions and a mid-region. The handle portion includes a distal region, proximal region and a central region positioned between the distal and proximal regions of the handle portion. The central and proximal regions of the handle portion have outer surfaces that define first and second transverse cross-sectional areas, respectively. The second transverse cross-sectional area is larger than the first transverse cross-sectional area. The pallet is coupled to and longitudinally extends over the central region but not over the proximal region of the handle portion. The butt cap is secured to the proximal region and includes a peripheral wall and less than half of the length of the peripheral wall extends over the pallet.

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. The length of the training bat is varied by adding or removing the body segments. The size and shape of the bat is varied by using the desired body segments of varying dimensions. The swing weight is varied by adjusting relative placement of body segments of varying weight along the length of the training bat in between the handle and the endcap from the proximal to the distal ends.

An interchangeable and weight adjustable golf grip including at least an end cap body having integral receiving ports adapted to receive variable weights, electronic chips, sensors, gauges, lasers, cameras, or biometrics within and wherein the end cap is capable of housing the various weights, chips, sensors, etc. within the end cap so that a player can interchange the weights or sensors without removing the golf grip from the shaft in order to make adjustments and so that the player can play golf without removing any other portions of the grip. Further, the invention includes contemplation of a tip collette with integral receiving ports adapted to also harbor similar weights, or sensors, etc. Data from the sensors may be transmitted by Bluetooth transmission to a smartphone or a ball launch monitor system for analysis.

A knob sleeve assembly for a ball bat extending along a longitudinal axis and having a tubular handle portion and a knob attached the handle portion. The knob sleeve assembly includes a plurality of annular bodies formed of a resilient material. Each of the bodies defines a central opening for receiving the handle portion of the bat. Each of the bodies has an annular body height within the range of 0.25 to 1.0 inch, and a maximum annular body outer diameter within the range of 1 to 3 inches. The plurality of annular bodies varies from one another according to at least one annular body characteristic. The knob sleeve characteristic is selected from the group consisting of annular body height, maximum annular body outer diameter, weight, color, material durometer value, annular body draft angle and combinations thereof.
