The present invention relates generally to a ball bat for use in sports training.
The game of baseball is engaged in by players of a range of age and skill. Players participating in each level of play, from Little League to the Major Leagues, must work to develop and maintain playing skills in order to achieve success. One key skill, “batting skill”, is particularly difficult to acquire and requires hours of practice, development of proper swing mechanics, development of strength, eye/hand ability, coordination and feel. It is commonly said that the act of making consistent solid contact with a round ball traveling at speed using a round bat may be the most difficult thing to do in sport. Developing confidence in doing so is even more difficult. Current training devices (in particular standard bats) present problems which are detrimental to developing skill and confidence.
One problem with standard bats is that off center hits cause a shock or “sting” to a batter's hands at impact. This problem is most pronounced when the ball impacts the barrel of the bat at a location along its length which is off of the area comprising the center of percussion, or “sweet spot” of the bat. This sting can cause a hitter to become anxious or otherwise fearful of making a hard swing at the ball.
A related problem is the difficulty of making contact with the sweet spot of the bat. The sweet spot of a bat (in general terms) is that area of the bat barrel which, when striking the ball, causes a maximum transfer of energy and a minimum transfer of vibration to the hands of the batter. With standard cylindrical bats, the sweet spot is relatively small compared to the diameter and length of the bat barrel. As a result it is difficult for developing hitters to make solid contact with it. A bigger bat barrel will have a bigger sweet spot but will also be heavier which is problematic for children or other developing hitters who have not yet developed adequate strength. Bats made of wood are used in the Major Leagues for various performance reasons and because they emit a preferable feel and sound to bats made of metal or composite materials when the ball is struck squarely. But bats made of wood, as stated, that have larger barrel diameters are too heavy for many batters to swing. And hollow bats made of metal or composite materials do not have a desirable feel and sound.
A big problem associated with wood bats is breakage. Broken bats are common in the Major Leagues where they are used to make contact with balls thrown at relatively high velocity. But, bat breakage at lower levels (even Little League levels) is problematic because bats made of wood (though relatively inexpensive to make and pleasing to use) are likely to break of splinter if the ball makes contact with the grain of the wood. The batter needs to hold a wood bat such that the ball makes contact against the grain of the wood barrel (i.e. for purposes of example, like striking the end of a deck of cards). This is difficult for young or developing hitters who haven't developed the focus (in paying attention to the grain), the training (from coaches, parents and others in how to hold the bat), or the strength (in terms of maintaining their grip on the bat as they make a swing to insure the bat doesn't turn in their hands before impact) to make proper contact using a wood bat. Thus, use of wood bats is discouraged in youth levels in games and/or in training, because wood bats break and are expensive to constantly replace and/or to reduce the risk of persons being injured by a broken or splintered bat.
Another problem associated with standard bats is that they do not encourage development of a level swing. It is preferable for hitters to develop level swings—that is swing the barrel at a plane where the barrel travels relatively parallel with the ground and as it enters the hitting zone—because balls are thrown so that they approach the strike zone on a substantially level plane. A level swing through the strike zone generally results in more consistent and solid contact with the ball. The roundness of the bat barrel makes it difficult for developing hitters to visualize that portion of the bat that they want to make contact with the ball. And, the roundness does not assist in providing an aerodynamic indication (that is difference in feel as the swing is being made) of when the swing is adequately level and when it is not.
As a result of these problems with standard cylindrical bats, developing hitters become fearful or anxious when making a swing, have difficulty making solid contact with the ball, miss out on the enjoyment of utilizing a wood bat, and otherwise have difficulty developing proper swing mechanics.
The present invention provides a training bat for use in ball sports including but not limited to baseball and softball which is adapted to address the problems and shortcomings associated with the prior art. A preferred embodiment of the bat has a elongated barrel of a substantially rectangular cross-sectional shape connected with a handle by a short tapered section. The hitting surface of the barrel is substantially flat with rounded edges and is of a lesser width front to back than each of the two parallel sides. The hitting surface of a preferred embodiment of the bat constructed in wood material is oriented such that the gran runs against the ball at contact thus making the hitting surface uniformly stronger than a standard cylindrical wood bat. The hitting surface provides for a narrower and relatively longer sweet spot than the standard cylindrical bat.
Various embodiments consistent with the principles of the invention will now be described. The following description provides specific details for a thorough understanding and enabling description of these embodiments. One skilled in the art will understand, however, that the invention may be practiced without many of these details. Additionally, some well-known structures or functions may not be shown or described in detail so as to avoid unnecessarily obscuring the relevant description of the various embodiments. The training bat described herein is designed for ball sports including but not limited to baseball and softball.
The terminology used in the description presented below is intended to be interpreted in its broadest reasonable manner, even though it is being used in conjunction with a detailed description of certain specific embodiments of the invention. Certain terms may even be emphasized below; however, any terminology intended to be interpreted in any restricted manner will be overtly and specifically defined as such in this detailed description section.
Where the context permits, singular or plural terms may also include the plural or singular term, respectively. Moreover, unless the word “or” is expressly limited to mean only a single item exclusive from the other items in a list of two or more items, then the use of “or” in such a list is to be interpreted as including (a) any single item in the list, (b) all of the items in the list, or (c) any combination of items in the list.
Turning now in detail to the drawings,
In the particular embodiments, the training bat 10 may be made of wood though it may alternatively be made of one or more composite or metallic materials. Some examples of suitable composite materials include fiber-reinforced glass, graphite, boron, carbon, aramid, ceramic, Kevlar, or Astroquartz®. Aluminum or another suitable metallic material may also be used to construct the bat. A training bat 10 including a combination of metallic and composite materials may also be constructed. For example, a training bat 10 having a metal barrel and a composite handle, or a composite barrel and a metal handle, may be used in the embodiments described herein. All bats used in Major League Baseball are made of wood for various reasons largely having to do with performance, feel and sound.
Wooden baseball and softball bats are typically formed from a single piece of ash wood, ash having desirable properties of hardness and strength. To produce a finished standard cylindrical baseball bat, a rectangular billet either rectangular or circular in cross-section is created in an appropriate length and diameter, typically approximately 37 inches long and approximately 2 and ¾ inches in width or diameter. The billet is cut so that the grain of the wood runs longitudinally, and is preferably taken from an outer section of the tree so that the grain runs in a relatively planar manner with as little curvature as possible. The billet is then shaped on a lathe to the particular desired length and profile, the bat having a thick striking portion or barrel, which is tapered into a relatively thin handle portion with a knob on the handle end. An infinite variety of profiles is possible. When striking the ball, a wooden bat is strongest against the grain, i.e., on the edge grain or when the striking angle is generally parallel to the face plane of the grain, meaning that there are only two optimum striking faces on each bat. If the player improperly rotates the bat so that the ball hits the bat too far off the exposed edge grain and onto the face grain, (which is easy to do with a standard cylindrical bat), the bat is more likely to crack or break. A preferred embodiment of the training bat is shaped to allow for a substantially rectangular barrel and oriented such that the shorter sides (including the hitting surface) expose the edge grain and the longer sides expose the face grain. The entire length of the hitting surface of the training bat exposes the strongest portion of the barrel upon which to make contact with the ball. The tapered area and handle may be cylindrical or substantially rectangular as shown in the drawings.
Thus, the knowledge and skill of the batter dictates, to some degree, the likelihood that a wood bat will break during use (for training or games) because the batter has to be careful to position the bat in his/her hand and swing such that the ball will hit the bat against the edge grain (i.e. where the bat is strongest). This is a substantial problem for children and others just learning to hit because it difficult to make consistent solid contact with the ball at that location on the bat where the grain is strongest. And, as a result, use of wood bats for children is discouraged not only for economic reasons (i.e. too many bats need to be replaced) but to reduce the risk of injury resulting from the sharp end or splinter of a broken bat. As discussed in detail below, one advantage of the present invention is that a batter striking the ball on the hitting surface will almost always strike the ball against the grain.
Width of the front side hitting surface. In preferred embodiments, the width of the front side hitting surface 22 of the training bat is functionally in the range 1⅝″ to 2″. A standard baseball is 2⅞″ to 3″ in diameter. Thus, it is preferable that the training bat have a hitting surface of approximately 2″ wide for making solid contact with the ball. It would be difficult to make consistent contact with a standard ball using a hitting surface with a width smaller than 1½″ although smaller hitting surface widths could be used in embodiments utilized by skilled hitters. The diameters of standard cylindrical bat barrels are typically 2¼″ to 2¾″. But the cylindrical nature of the standard bat means that the hitting surface (which may be defined as a surface upon which the batter may make contact and have the ball travel in the direction of the swing) on a standard bat is round and, while the material compresses at impact with the ball, there is actually less than 1″ of hitting surface contacting the ball at impact. In other words, while there may be more area of the bat to make contact with the ball with a standard cylindrical barrel bat, making contact outside of the hitting surface would cause the ball to glance off the bat in an unintended up or down direction (such as will a foul ball). Thus, the hitting surface of the training bat is functionally wider than the hitting surface of the standard cylindrical bat because contact with any portion of the hitting surface will result in the ball traveling in the relative direction of the swing and would only glace off if struck at the rounded edges where the hitting surface meets the adjacent perpendicular side of the barrel.
Width of the hitting surface relative to the perpendicular sides. The width of the front side hitting surface relative to the right and left side surfaces can vary except that it is preferable that the front side hitting surface be roughly half as wide at the adjacent right and left perpendicular sides of the barrel for purposes of providing aerodynamics which would encourage proper swing mechanics and because wider perpendicular sides will preserve strength and reduce flex of the barrel at impact as discussed above.
Length of the hitting surface relative to the bat length. Generally, the length of the hitting surface of the standard bat as well as the training bat will be greater than the length of the handle and tapered section combined. The length of the barrel (i.e. the hitting surface) of the embodiment shown in
Alternative configurations of the barrel. An alternative embodiment may utilize a barrel having a trapezoidal, rather than rectangular shape. In this alternative configuration, the right and left side surfaces aren't parallel but instead extend from a front side hitting surface that is wider to an opposing back side (which may or may not have a hitting surface) that is relatively narrower than the front side. For example, such alternative embodiment might have one front side hitting surface that is 2″ wide with an opposing back side of 2½″ with right and left sides roughly 3½″ to 4″ wide. Such configuration is consistent with the principle that the hitting surfaces are flat with rounded edges and extend at a consistent width down the length of the barrel. A variety of barrel shapes are consistent with the principles described above.
Fig. shows 5 is a comparison view of a standard cylindrical bat (on the left) and an embodiment of the training bat (on the right) with front side hitting surface of the training bat facing forward. That portion of both bats in dotted lines shows the relative sweet spots of the two bats. One will note that the sweet spot of the training bat is relatively longer and wider than that of the standard bat of similar length and, as shown in
A method for making a preferred embodiment of the training bat depicted in
As one can appreciate from the discussion above, the training bat provides substantial advantages over the standard bat for purposes of training the swing and developing confidence in the hitter. The following is a list of some of these advantages:
One will note that the training bat described above is for use in ball sports such as baseball and softball which generally involve the use of a cylindrical bat during competitive play. Although the invention has a substantially flat hitting surface for purposes of training the hitters swing, it differs substantially from a cricket bat or similar paddle shaped implement for striking a ball wherein the hitting surface of the bat/paddle is substantially wider than the barrel side surfaces. In the present invention, the hitting surface is narrower than the barrel side surfaces. One will also note that while the barrel of the present invention has uniform side surfaces which are substantially parallel to the substantially flat hitting surface, there is no requirement that those side surfaces be necessarily parallel in that they might, in alternative embodiments, connect a surface opposite the hitting surface which is wider or narrower than the hitting surface.
