| 473520000 | With sound-deadening, vibration-damping, or shock-absorbing feature other than projectile- or hand-contact surface or with rebound reducing feature | 30 |
| 20090280932 | Hand implement vibration isolation system - A vibration isolation system for hand implements including sporting equipment and tools to substantially reduce impact forces from being delivered to the user's hands. Isolation elements provide low spring rates enabling the system to isolate bending vibration, recoil, and twist. An outer shell member substantially encircles the grip end of the hand implement and is spaced outwardly thereto allowing the grip end to freely deflect within the outer shell member. | 11-12-2009 |
| 20110098141 | Vibration dampening ball bat - The present invention relates to a ball bat with improved shock and vibration dampening. More particularly, the present invention relates to a ball bat with a handle, a barrel, and a socket assembly interposed between the handle and barrel. The socket assembly allows the barrel and handle to move relative to each other, which dampens shock and vibration. | 04-28-2011 |
| 20110111892 | BAT WITH HANDLE HAVING INTERNAL CORE MEMBER AND METHOD OF MAKING SAME - A bat is provided including a handle portion, a barrel portion and a core member. The barrel portion has an interior cavity with an interior surface. The core member is disposed in the interior cavity of the barrel portion. The core member has an exterior surface engaged with the interior surface of the barrel portion. The handle portion extends into the interior cavity of the barrel portion and is coupled to the core member. The coupling of the core member to the handle allows the impact of the barrel portion on a ball to be transmitted to the user through the core member and the handle portion. The bat may thereby provide the user with an increased sense of the quality of the contact with the ball. | 05-12-2011 |
| 20110152015 | Ball bat with internal impact dampening means - Industry regulatory organizations have created performance restrictions for ball bats. The present invention relates to a ball bat with an internal impact dampening means. More particularly, the present invention relates to a ball bat with a handle, a barrel, and a central tube positioned coaxially within the barrel. The central tube includes at least one restriction member capable of limiting the deformation experienced by the ball bat upon impact of a ball. Precisely limiting the deformation of the ball bat allows the present invention to achieve, but not exceed, performance substantially equal to the maximum performance allowed by industry regulatory organizations and maintain that level of performance over a substantial length of the ball bat. | 06-23-2011 |
| 20110281673 | Ball bats - Ball bats comprising a stem and a handle surrounding the stem. An elastomeric decoupler system installed in the handle sharply reduces the transmission of shocks and vibrations from the stem to the handle, mitigating stinging and other unpleasant sensations experienced by the batter when a ball is struck. Unpleasant sensations can be further reduced by installing a DTMS damping device in the knob of the bat and by installing an elastomeric grip on the handle of the bat; and the unpleasant sound made when a bat strikes the ground or the like can be materially reduced by a device attached to the stem of the bat intermediate the ends of the handle. The present inventions are particularly adaptable to hollow, metal bats; and provision is made for venting the knob of the bat when it is welded in place so hot gases will not be forced into, and reduce the integrity of, the weld. Appropriate ones of the devices described above may also advantageously be employed in wood, composite, and other bats. | 11-17-2011 |
| 20120184402 | Bat With Stiffening Insert - A tubular bat having a barrel of thin walls is stiffened by rings to adjust and tune performance. The walls of a bat is thinned to reduce weight and to enhance a batters control. However, regulatory bodies dictate performance standards that may require stiffer walls. Additionally different regulatory bodies dictate different standards. Therefore in order to meet regulatory standards in various jurisdictions, the walls of the bat barrel may be stiffened using rings to adjust and tune performance while minimizing the weight of the bat. The design, size and material from which the ring is made may vary. The placement of the ring may be used to tune specific performance profile of a bat. | 07-19-2012 |
