  • EXAMPLES Example 1
  • Referring now to FIG. 1 of the drawings, representing an example disclosed herein, a cross-section of Support structure 10 is shown. Support structure 10 comprises a Center ring 20 surrounding a Central opening 30. Departing from Center ring 20 at approximately equally spaced intervals around the circumference of Center ring 20 are Curved spokes 40. Curved spokes 40 depart from Center ring 20 at an angle that is neither radial with respect to Center ring 20 nor tangential to Center ring 20, but attaches to and departs from Center ring 20 at an angle that is between radial and tangential. Support structure 10 may be included within the barrel of a bat (not shown), which may be an aluminum baseball or softball bat, such that each of Curved spokes 40 arc out from Center ring 20 in the direction of the portion of the barrel of the bat that is nearest the point of attachment of Center ring 20 to the relevant Curved spoke 40. Curved spoke 40 follows a first arc path in between Center ring 20 and the bat barrel and Curved spoke 40 transitions into following a second arc path at End of curved spoke 50 which is the point where Curved spoke 40 would be adjacent to the barrel of the bat when Support structure 10 is in the barrel of a bat. In the present embodiment Curved spoke 40 has a first arc path that has an arc radius that is less than one half of, but greater than one fourth of the radius of Support structure 10. At End of curved spoke 50 Curved spoke 40 follows a second arc path having an arc radius that is substantially the same as the radius of Support structure 10 with that arc radius being either equivalent to or slightly less than the radius of the internal circumference of the bat barrel. In an alternate embodiment, End of curved spoke 50 is either straight or has a larger radius arc than Bat barrel 60, but is flexible enough to form an arc having a radius comparable to the arc made by the internal circumference of the bat barrel.
  • FIG. 2 of the drawings is a partial perspective view of the embodiment depicted and FIG. 1 of the drawings. Elements of the embodiments depicted in FIG. 2 of the drawings are the same as described in the treatment of FIG. 1 above. The embodiment depicted in FIG. 2 is a truncated depiction of Support structure 10 which may have a length sufficient to fill the inside of Bat barrel 60 (not shown).
  • Example 2
  • FIG. 3 of the drawings is an embodiment in which Support structure 10 is located within Bat barrel 60. The view presented in FIG. 3 is from a perspective situated along the central axis of Bat barrel 60 and looking down Bat barrel 60. Each of the component parts of Support structure 10 are arranged in a manner comparable to that depicted in FIG. 1 of the drawings. Curved spoke 40 arcs gradually from Center ring 20 toward Bat barrel 60 with the arc of Curved spoke 40 transitioning into an arc of greater radius at or near the point where Curved spoke 40 contacts Bat barrel 60 such that Curved spoke 40 has an area of contact with Bat barrel 60 in the region of End of curved spoke 50. The arc of Curved spoke 40 may be comparable to the arc of Bat barrel 60 such that End of curved spoke 50 lies along and in contact with Bat barrel 60. The fit between Curved spoke 40 and Bat barrel 60 may be a friction fit as is shown in the present embodiment.
  • Example 3
  • FIG. 4 of the drawings is an embodiment in which Support structure 10 is located within Sleeve 90 which is located within Bat barrel 60. In the present embodiment, Sleeve 90 is in the form of a cylinder. The view presented in FIG. 4 is from a perspective situated along the central axis of Bat barrel 60 and looking down Bat barrel 60. Component parts of Support structure 10 are arranged in a manner comparable to that depicted in FIG. 3 of the drawings. Curved spoke 40 arcs gradually from Center ring 20 toward Sleeve 90 with the arc of Curved spoke 40 transitioning into an arc of greater radius at or near the point where curved spoke contacts Sleeve 90 such that Curved spoke has an area of contact with Sleeve 90 in the region of End of curved spoke 50. The arc of Curved spoke 40 may be comparable to the arc of Sleeve 90 such that End of curved spoke 50 lies along and in contact with Sleeve 90. Similarly, Sleeve 90 is arranged and configured to fit closely and securely within Bat barrel 60 with little or no gap between Bat barrel 60 and Sleeve 90. The fit between Curved spoke 40 and Sleeve 90 may be a friction fit such as the fit shown in FIG. 4. The fit between Sleeve 90 and Bat barrel 60 may be either a close fit or a friction fit.
  • FIG. 5 is an embodiment of the invention configured similarly to the embodiment depicted in FIG. 4. Support structure 10 comprising Center ring 20, Central opening 30, and Curved spoke 40 including End of curved spoke 50 is situated and frictionally fit within Sleeve 90. Sleeve 90 is situated within and may be frictionally fit within Bat barrel 60. Support structure 10 and Sleeve 90 may extend through either a portion of the cylindrical section of Bat barrel 60 or may extend the entire length of the cylindrical section of Bat barrel 60. Sleeve 90 and Support structure 10 provide additional support to Bat barrel 60 and reduce plastic the formation and denting of both Bat barrel 60 and Bat 70.
  • While the embodiment depicted in FIGS. 1 and 2 of the drawings contains six Curved spokes 40 which are each similarly configured and substantially evenly spaced around Support structure 10, descriptions contained herein focus on the configurations of individual Curved spokes 40. The present embodiment and each subsequently described embodiment should be understood as describing a variety of related embodiments having 3-12 spokes configured as those Curved spokes 40 are described in the individual examples each of the spokes being substantially evenly spaced around a central support structure.
  • Example 4
  • Referring now to FIG. 6 of the drawings, Support structure 10 comprising Center ring 20, Central opening 30, and Curved spoke 40 including End of curved spoke 50 is situated and frictionally fit within Sleeve 90. Sleeve 90, unlike the version of sleeve 90 depicted in FIG. 4 of the drawings, contains substantial departures from a cylindrical form. Sleeve 90 has two or more Wall protrusions 95 and, as shown in FIG. 6, may have a number of Wall protrusions equivalent to the number of Curved spokes 40. Further, Curved spoke 40 is thickest at the point of attachment to Center ring 20. Protrusions such as Wall protrusions 95 and/or the reinforcement of Curved spoke 40 as depicted in FIG. 6 or other equivalent structures may be applied to any of the embodiments described herein.
  • Example 5
  • In an alternate embodiment, related to FIG. 6 of the drawings, but not shown in a separate figure, Bat 70 may comprise Bat barrel 60 and Support structure 10 without the presence of Sleeve 90. In that embodiment, protrusions equivalent to Wall protrusions 95, shown protruding from Sleeve 90, protrude from Bat barrel 60 forming a relationship between Curved spoke 40 and Bat barrel 60 that is comparable to the relationship depicted in FIG. 6. Such protrusions from the bat barrel aid in the retention of Support structure 10 in its position within Bat barrel 60 and limits the potential motion of End of curved spoke 50 during compression and deformation of Bat barrel 60 during the striking of a ball with Bat 70.
  • Example 6
  • FIG. 7 illustrates the geometry of certain embodiments of Curved spoke 40 near the point where Curved spoke 40 contacts either Bat barrel 60 or Sleeve 90. Wall contacting spoke portion 120 is a portion of Curved spoke 40 that is in contact with the surface of Bat barrel 60. Near wall spoke portion 130 is a portion of Curved spoke 40 that is near the surface of Bat barrel 60 but not in contact with Bat barrel 60. Point of departure 140 represents the point at which Curved spoke 40 separates from Bat barrel 60 and represents the point at which Wall contacting spoke portion 120 meets Near wall spoke portion 130. As illustrated in FIG. 7 Wall contacting spoke portion is configured as an arc having an arc radius comparable to the arc radius of Bat barrel 60. Near wall spoke portion 130 is configured as an arc having an arc radius that is substantially less than the arc radius of Wall contacting spoke portion 120. The arc radius of Near wall spoke portion 130 may be less than 75% of the internal radius of Bat barrel 60. The arc radius of Near wall spoke portion may be less than 50% of the internal radius of Bat barrel 60. In a separate but related embodiments, the arc radius of Near wall spoke portion 130 may be greater than 25% of the internal radius of Bat barrel 60 and the arc radius of Near wall spoke portion 130 may be greater than 30% of the internal radius of Bat barrel 60. As shown in FIG. 7, the arc of Near wall spoke portion 130 may smoothly transition into the arc of Wall contacting spoke portion 120 so that there is no appreciable angle at Point of departure 140. Such transition may for example be either a direct and immediate transition between the arc of Wall contacting spoke portion 120 and the arc of Near wall spoke portion 130 or may be a more gradual transition involving multiple arc radii or a continuously decreasing arc radius near Point of departure 140.
  • Although the present example describes a configuration in which Curved spoke 40 comes in contact with Bat barrel 60, the geometric descriptions of Curved spoke 40 described above in the present example are also contemplated as a separate embodiment having similar geometry in which Curved spoke 40 is in contact with Sleeve 90.
  • Example 7
  • Referring now to FIG. 8 of the drawings, Curved spoke 40 may be configured such that Wall contacting spoke portion 120 has a first arc comparable to that of Bat barrel 60, such that Near wall spoke portion 130 has a second arc, and such that wall contacting spoke portion 120 meets near wall spoke portion 130 at Point of departure 140. In the present example, Curved spoke 40 creates an Angle of departure 145 which represents the angle at which near wall spoke portion departs from Bat barrel 60 at Point of departure 140. Angle of departure 145 may be less than 50°. In separate but related embodiments Angle of departure 145 may be less than 35° and Angle of departure 145 may be less than 20°. In a series of related embodiments, any of the above described geometric descriptions of the present example may be used in conjunction with Sleeve 90.

Sleeve 90 lies within Bat barrel 60 as described above.
  • Example 9
  • Referring now to FIG. 10 of the drawings, Curved spoke 40 may be configured such that it departs from Center ring 20 tangentially and arcs toward the portion of Sleeve 90 that is closest to the point of attachment of Curved spoke 40 to Center ring 20. In the present embodiment, Curved spoke 40 approaches and contacts Sleeve 90 in a manner comparable to the manner described in either Example 6 or Example 7. Sleeve 90 lies within Bat barrel 60 as described above.
  • Example 10
  • Referring now to FIG. 11 of the drawings, Hexagonal center 210 may serve as the center of Support structure 10 such that each side of the hexagon formed by Hexagonal center 200 continues outward on one side to form the beginning of Curved spoke 40 which ultimately arcs outward approaching and contacting Sleeve 90 in a manner comparable to the manner described in either Example 6 or Example 7. Sleeve 90 lies within Bat barrel 60 as described above.
  • In alternate related embodiments the geometric center of Support structure 10 may take a variety of geometric forms including but not limited to a square, a pentagon, a heptagon, an octagon, etc.
  • Example 11
  • Referring now to FIG. 12 of the drawings, Curved spoke 40 may be configured such that it departs from Center ring 20 tangentially and arcs away from the portion of Sleeve 90 that is closest to the point of attachment of Curved spoke 40 to Center ring 20. In the present embodiment, Curved spoke 40 approaches and contacts Sleeve 90 in a manner comparable to the manner described in either Example 6 or Example 7. Sleeve 90 lies within Bat barrel 60 as described above.
  • Example 12
  • Referring now to FIG. 13 of the drawings, Curved spoke 40 may be configured such that it departs from Center ring 20 tangentially or near tangentially and arcs toward the portion of Sleeve 90 that is closest to the point of attachment of Curved spoke 40 to Center ring 20. In the present embodiment, Curved spoke 40 approaches and contacts Sleeve 90 in a manner comparable to the manner described in either Example 6 or Example 7. Additionally, Center ring 20 has a diameter that is greater than 50% of the internal diameter of Bat barrel 60. Sleeve 90 lies within Bat barrel 60 as described above.
  • Additional Examples
  • Referring now to FIG. 14 of the drawings, embodiments described herein, and in particular the configurations of individual versions of Curved spoke 40 may be understood by viewing Support structure 10 looking down Bat barrel 60 from the Bat barrel 60 end of the Bat 70 and by using Point of attachment 305 as a reference point from which the geometry of Curved spoke 40 may be understood. The examples that immediately follow and refer to FIG. 14 described embodiments which arc in the clockwise direction as Curved spoke 40 approaches Sleeve 90. These examples should be understood to also representing an equivalent number of counter examples having equivalent geometry but having a direction of arc that is in the counterclockwise direction as Curved spoke 40 approaches Sleeve 90. Each of the examples described in the present set of Examples are described with respect to Sleeve 90. In embodiments not having Sleeve 90 the geometric references to Sleeve 90 would apply to Bat barrel 60. Furthermore, the number of Curved spokes 40 in these embodiments may vary from 3-12.
  • Point of attachment 305 is the point of intersection of the centerline of Curved spoke 40 as it intersects with Center ring 20. Using Point of attachment 305 as a frame of reference, Reference line 310 is a line that tangentially departs from Point of attachment 305 with respect to Center ring 20, Reference line 340 is a line that extends from Point of attachment 305 in a direction that is radial from Center ring 20, and Reference line 370 is a line that tangentially departs from Point of attachment 305 opposite Reference line 310. Line segments are sometimes referred to herein as lines for the sake of brevity. Reference line 340 is 90° clockwise from Reference line 310 and Reference line 370 is 90° clockwise from Reference line 340. Each of Reference lines 320, 330, 340, 350, 360, 370, 380, 390, and 400 originate from Point of attachment 305 and those reference lines are 30°, 60°, 90°, 120°, 150°, 180°, 210°, 240°, and 270° clockwise from Reference line 310 respectively. First section 420 is the area between Reference line 310 and Reference line 320. Second section 430 is the area between Reference line 320 and Reference line 330. Third section 440 is the area between Reference line 330 and Reference line 340. Fourth section 450 is the area between Reference line 340 and Reference line 350. Fifth section 460 is the area between Reference line 350 and Reference line 360. Sixth section 470 is the area between Reference line 360 and Reference line 370. Seventh section 480 is the area between Reference line 370 and Reference line 380. Eighth section 490 is the area between Reference line 380 and Reference line 390. Ninth section 500 is the area between Reference line 390 and Reference line 400. Reference line 310 is sometimes referred to herein as the “primary tangent line.” In embodiments where the center of Support structure 10 is not cylindrical/circular the following descriptions associated with FIG. 14 may be adjusted to account for the differing geometry. In such cases, the smallest circular/cylindrical area/space that is coaxial with the bat barrel and that fully encompasses the central structure is referred to as the “central region.” Non-circular/non-cylindrical central structures may have one or more of the geometries described herein with reference to FIG. 14 with Point of attachment 305 referring to the point of departure of Curved spoke 40 from the central region. In such embodiments the primary tangent line is tangential to the perimeter of the central region.

  • As that term is used herein the “barrel” of a bat is the portion of a bat that is substantially cylindrical and is commonly used to strike a ball such as in the game of baseball. As that term is used herein “adjacent” when used in the context of structures near a bat barrel is intended to encompass all structures having a close spatial relationship with the bat barrel, the spatial relationship being sufficiently close to reduce the plastic deformation of the bat barrel when the bat barrel is impacted by a baseball traveling at 100 miles per hour in a direction normal to the surface of the bat barrel as compared to the deformation under similar circumstances without the structure wherein the baseball meets the specifications for use as in major league baseball for the 2012 season. For example, as shown in FIG. 4 of the drawings, End of curved spoke 50 would be considered adjacent to Bat barrel 60 in spite of being separated from Bat barrel 60 by Sleeve 90.
  • There are, of course, other alternate embodiments which are obvious from the foregoing descriptions of the invention, which are intended to be included within the scope of the invention, as defined by the following claims.
