| 20090170643 | Toy Bat and Ball Set - A toy bat and ball set is provided. The bat may include a shell having a proximate portion formed as a handle, and a distal portion formed in the shape of a barrel with an outer hitting surface, the distal portion including an opening on a distal end leading to a void formed in an interior region of the shell of the bat, the opening being bounded at least partially around a perimeter of the opening by a lip. The ball may be a resiliently deformable ball able to be deformed to a reduced diameter that is smaller than the opening, such that the ball can be inserted through the opening into the void in the shell of the bat, and expanded within the void, to thereby be secured within a ball-receiving region of the void by the lip. | 07-02-2009 |
| 20090197712 | BALL BAT EXHIBITING OPTIMIZED PERFORMANCE VIA SELECTIVE PLACEMENT OF INTERLAMINAR SHEAR CONTROL ZONES - A ball bat exhibits improved barrel performance in regions located away from the “sweet spot” of the bat barrel, as a result of strategic placement of interface shear control zones (“ISCZs”) in the barrel. The ball bat includes a barrel having a first region adjacent to the tapered section of the ball bat, a second region adjacent to the free end of the barrel, and a third region located between the first and second regions, that includes the sweet spot of the barrel. The first and second regions each include at least one interface shear control zone. The third region includes at least one fewer interface shear control zone than at least one of the first and second regions. ISCZs may also be strategically placed in the bat handle and/or the tapered section of the ball bat to improve the compliance and overall performance of the ball bat. | 08-06-2009 |
| 20090215559 | Layered Composite Material Bat - A layered composite bat is designed to include fiber angles of orientation that are layered and progressive. The bat includes a multi-layered composite material configuration wherein progressing from an innermost layer to an outermost layer, the unidirectional fiber angle of orientation within each layer increases from an angle substantially parallel to the longitudinal axis of the bat to an angle substantially perpendicular to the longitudinal axis of the bat. In progressing from an innermost layer to an outermost layer, there also exists at least one instance where subsequent positive angles of orientation are separated by or vary by about 15 degrees. The bat may include multiple walls. Each wall contains layers that progress from a low angle to a high angle in 15-degree increments. | 08-27-2009 |
| 20090215560 | Composite Bat - A bat includes a composite material barrel. The barrel includes a plurality of layers. A stiffening layer forms one of the exterior layers of the barrel. The stiffening layer includes unidirectional fibers, where the unidirectional fibers are oriented to substantially encircle the barrel. The stiffening layer is positioned on the barrel to cover at least a portion of the sweet zone. The barrel may include multiple walls, where each wall includes a stiffening layer. | 08-27-2009 |
| 20090264230 | COMPOSITE BAT - A bat has a barrel with a multi-wall construction. The handle can be formed integrally with the inner wall. A damping device can be installed between the handle and the outer wall of the barrel. The damping device can dampen vibrations transmitted from the outer wall to the handle. The damping device can also separate the outer wall from the inner wall adjacent the handle section. The inner and outer walls can be bonded together adjacent the end of the bat. Alternatively, the inner and outer walls can be entirely free of bonding to one another. Additionally, a damping device can separate the outer wall from the inner wall adjacent the end of the bat. Furthermore, the bat can include a pair of damping devices that separate the inner wall from the outer wall both adjacent the handle section and at the end of the bat. | 10-22-2009 |
| 20100022334 | INJECTION-MOLDED BALL BAT - A bat and a method of making a bat for use in sports, such as baseball. The bat includes a one-piece, hollow bat frame formed by injection molding a durable polymer, such as acrylonitrile butadiene styrene. The bat frame includes a barrel portion, an intermediate portion, and a handle portion, with at least one of the portions having a polygonal cross-section on an interior surface of the bat. | 01-28-2010 |
| 20110086734 | Baseball Bat - A baseball bat includes a hollow grip member having opposite front and rear ends, and an inner peripheral surface that defines a tapered chamber having a diameter reducing gradually toward the rear end. The inner peripheral surface has a first positioning portion disposed between the front end and the rear end. A striking member has an engaging segment received in the tapered chamber, and a large diameter segment extending forwardly from the engaging segment. The engaging segment has an axial hole, a plurality of open-ended slits extending along an axial direction and in spatial communication with the axial hole, and a second positioning portion aligned with the first positioning portion. A pressing member is inserted into the axial hole to press the second positioning portion against the first positioning portion. | 04-14-2011 |
| 20120142461 | BALL BAT INCLUDING MULTIPLE FAILURE PLANES - A composite ball bat includes multiple failure planes within a barrel wall. By including multiple failure planes in a barrel wall, the bat exhibits a drop in performance when subjected to rolling or other extreme deflection, with no temporary increase in barrel performance. Because the barrel performance does not increase, the ball bat is able to comply with performance limitations imposed by regulatory associations. | 06-07-2012 |
| 20130184107 | BALL BAT HAVING IMPROVED STRUCTURE TO ALLOW FOR DETECTION OF ROLLING - A ball bat extending about a longitudinal axis. The bat includes a handle and a barrel portion. The barrel portion has a total length and includes a barrel rolling detection region having a length of at least two inches. The detection region is formed of a fiber composite material. The composite material includes at least first and second plies. The first and second plies each include first and second pluralities of fibers aligned adjacent to one another and first and second resins, respectively. The first and second pluralities of fibers of the first and second plies are generally aligned to define first and second angles with respect to the axis, respectively. The first ply is positioned over and within 0.002 in of the second ply. The first and second angles are each within the range of 20 to 80 degrees.
