The present invention relates to devices for training hitting for the sport of baseball.
In the game of baseball, bats are used to hit a ball into or out of (in the case of a homerun) a field. Proper swing mechanics are needed in order to have the ball fly a maximum distance. At the speeds (around 100 miles per hour) professional players hit the ball, maximum distance is generally achieved with a ball launch angle of about 25-30 degrees from a “sweet spot” on the bat. The sweet spot is a location on the bat that causes the ball to launch at the highest velocity with proper swing mechanics. The “sweet spot” is generally around 70-80 percent down the length of the bat (from handle end to hitting end) and is determined by several factors such as material, balance point vibration nodes, and the like. Younger players or amateur players (depending on strength) may achieve a maximum distance with a launch angle of around 30-40 degrees because of less air resistance for lower speed. Further, for maximum launch speed, the ball must be in the proper location at the time of contact with the bat. Generally, maximum launch speed and maximum distance is achieved by hitting the ball when the ball is arriving from the pitcher at the front of home plate. This gives the hitter a greater amount of time to accelerate the bat without the contact angle (about 80-90 degrees in the plane of the playing field) reducing the energy transferred to the ball.
Accordingly, in order to achieve maximum distance, a player must hit the ball at the sweet spot (aim), with the ball at the proper location over the plate (timing), with the bat traveling with the proper angle (swing mechanics), and speed (strength) to impart maximum kinetic energy to the ball and cause the ball to travel in the optimal direction. Accordingly, a baseball player must develop aim, timing, proper swing mechanics with proper hand and bat path, and strength in order to be an effective long ball (e.g., home run) hitter.
Many swing training devices exist that assist baseball players develop one or two of the above-mentioned factors (aim, timing, proper swing mechanics, and strength). However, no previously existing devices exist that can effectively assist a hitter in all of these factors.
One or more embodiments are provided below for a device for a training bat. The training bat may include a shaft and a hitting head. The shaft may include a handle and hand placement indicators. The shaft may include a first end and a second end. The hitting head may be attached to the second end of the shaft. The hitting head may include a flat hitting surface which is substantially flat and a back end opposite the flat hitting surface. The hand placement indicators may indicate a position for at least one of the hands of a user on the handle and the hand placement indicators may indicate an alignment with the back end of the hitting head.
The device may provide significant advantages over the other devices due to the inclusion of one or more of: (1) a hitting head at a distance from the knob that simulates the sweet spot of an ordinary bat which assists with aim, (2) a counter weight that causes the training bat that may have greater weight and shorter length to a normal bat to have a similar feel when swung as an ordinary baseball bat, assisting with strength, timing, and proper swing mechanics, (3) a shaft that matches a baseball bat in shape and feel, assisting with proper swing mechanics, (4) indicators of hand positioning for a split grip that in combination with the orientation of the hitting head enforce proper swing mechanics, and (5) construction and materials that allow for the training bat to make contact with a baseball without compromising the structure of the training bat, allowing the bat to be used with a thrown baseball assisting with timing and aim.
Other advantageous features as well as other aspects and advantages of the invention will be apparent from the following description and the appended claims.

The shaft 140 may have a handle area 142 that may or may not be wrapped with a grip (not shown) of leather, plastic, cloth, or other material. The overall length of bat 100 can be between 26-36 inches and the handle area 142 may be about 13-18 inches in length. The shaft 140 at the taper 144 portion may increase in diameter as the distance from the knob 120 increases to a broadest point of about 2½-2⅘ inches. The hitting head 160 may be connected to or proximate to a second end of the shaft 140 (opposite the first end at the handle area 142 or knob 120). The hitting head 160 may be a cylinder of rubber, wood, or other durable somewhat elastic material suitable for striking a baseball. The hitting head 160 may have a diameter of about 2-4 inches and a height of about 3-5 inches. Accordingly, the hitting head 160 may extend beyond the diameter of the shaft 140. The hitting head 160 may weigh about 10-20 ounces. The hitting head 160 may be fixed to the shaft 140 by screws, a shaped plug, screwing on to threading on the shaft 140, glue, etc. The back face 162 of the hitting head 160 may be flat or may be concave or convex to adjust the weight of the hitting head 160.
The handle area 142 may include hand placement indicators placed relative to the alignment of the hitting head 160 to promote palm up palm down hand positioning at the point of contact. The hand placement indicators may be printed or painted on a grip on the handle area 142, may be indents in the handle area 142, or any other form of indication either visual or by feeling with the hands. For example, the hand placement indicators may include left hand palm indicator 122, right hand palm indicator 132, left hand finger indicators 124, right hand finger indicators 134, left hand thumb indicator 126, and right hand thumb indicator 136. The arrangement of the hand placement indicators in
The left hand palm indicator 122 may show where the palm of the left hand should be placed on the training bat 100. The left hand palm indicator 122 may be a long thick line indicating a line across the palm from the thenar webbing (between the thumb and first finger) to the outside of the hand (e.g. the outside of the metacarpal attached to the fourth finger). From the perspective of
The left finger indicators 124 may show a placement of fingers of the left hand on the handle area 142. The left finger indicators 124 may include one indicator for each finger on the left hand. The left finger indicators 124 may indicate placement of the fingers for an average sized hand relative to the left hand palm indicator 122. For example, the left finger indicators 124 may be 70-90 degrees directly below (from the perspective of
The left thumb indicator 126 may show a placement of a first digit of a thumb of the left hand on the handle area 142. The left thumb indicator 126 may be about 1 inch long extending down (from the perspective of
The right hand palm indicator 132 may show a placement of the right palm on the handle area 142. The right hand palm indicator 132 may be a long thick line indicating a line across the palm from the thenar webbing (between the thumb and first finger) to the outside of the hand (e.g. the outside of the metacarpal attached to the fourth finger). The right hand palm indicator 132 may start about 5-8 inches further from the knob 120 than the left thumb indicator 126 and extend about 3 inches away from the knob 120. The right hand palm indicator 132 may be about 90 degrees below (from the perspective of
The right finger indicators 134 may show a placement of fingers of the right hand on the handle area 142. The right finger indicators 134 may indicate placement of the fingers for an average sized hand relative to the right hand palm indicator 132. For example, the right finger indicators 134 may be 70-90 degrees directly above (from the perspective of
The right thumb indicator 136 may show a placement of a first digit of a thumb of the right hand on the handle area 142. The right thumb indicator 136 may be about 1 inch long extending up (from the perspective of
The locations and dimensions of the hand placement indicators are given as examples and may be modified for several reasons without departing from the principles of the inventive concepts discussed herein. Some examples of reasons to modify the hand placement indicators are hitters with different sized hands, different desired launch angles (as discussed in the background, professional players have the longest flight with an angle of about 25-30 degrees while amateurs or children may have the longest flight with a launch angle of 30-40 degrees due to lower air resistance at lower speeds), left handed vs. right handed players, preference for placement of hand along the handle area 142 (e.g. how choked up the player's hands are), etc.
As discussed in greater detail below, the placement of the hand placement indicators is related to the orientation of the hitting head 160 and helps to enforce proper swing mechanics. The example hand placement indicators of
In one embodiment, the counterweight 110 may weigh 9 ounces and have a height (from the perspective of
Professional baseball bats may be up to 36 inches in length but are often about 32-35 inches long. Accordingly, the sweet spot may be at about 26-32 inches from the handle end of the bat (depending on overall bat length). Bats for children and amateur baseball players are often shorter in order to be lighter and easier to swing. Children's bats may be as short as 24 inches. Accordingly, the sweet spot for children's or adolescent's bats may be about 20-27 inches from the handle end of the bat (depending on overall bat length).
Accordingly, in one example embodiment for adult players, the shaft 140 may be about 30-34 inches from knob 120 to the hitting head 160 and the hitting head 160 may be about 2-3 inches in diameter. In some embodiments, (especially for new baseball players who have difficulty aiming and need to work on swing mechanics) the hitting head 160 may be larger; in some embodiments up to 6 inches in diameter. In a second embodiment for adolescent players, the shaft 140 may be about 22 inches long and the hitting head 160 may be about 3 inches in diameter (but less dense or hollow to reduce weight). Weight may also be reduced by changing the shape of the hitting head to be bullet shaped or otherwise modified to reduce weight. In a third embodiment for young children, the shaft 140 may be about 17 inches long and the hitting head 160 may be about 3 inches in diameter and hollow or otherwise reduced in weight. Accordingly, in various embodiments the shaft 140 may be about 16 inches to about 34 inches long. For adult sized bats, the shaft 140 may be about 28-34 inches in length.
In some embodiments, front face 164 is a hitting face. Front face 164 may be a flat circular surface oriented about parallel (within 5 degrees) to the direction the center of the shaft 140 extends. In other embodiments, the front face 164 may have a different shape, such as a square, oval or other shape or may be slightly angled (up to 15 degrees) relative to the direction that the center of the shaft 140 extends. Portions of the hand placement indicators (e.g., the left thumb indicator 126 and the right thumb indicator 136) are also depicted in
The dial 138 allows a user to see the orientation of the hands relative to the front hitting face 164 and allows users to make slight adjustments while honing his or her skills. The dial 138 can be used by people having virtually any hand size.
In general, the location of hand position indicators relative to the hitting face helps to teach and enforce proper swing mechanics to achieve palm up palm down at contact. Referring back to
In other aspects, the hitting head 160 is attached to shaft 140 at a fixed position prohibiting (and possibly preventing) movement of the hitting head 160. The shaft 140 may have a first end where the knob 120 attaches to the shaft 140 and a second end opposite the first end. The hitting head 160 may be attached to the shaft 140 proximate to the second end (i.e., much closer to the second end than the first end).
In general, when a person swings a bat with their hands in the proper position, a ball in a strike box (of the game of baseball) at the front edge of home plate (relative to a batter in the game of baseball) can be hit at a proper launch angle (e.g, between 25-40 degrees) and direction with proper swing mechanics. Proper swing mechanics can include keeping the trailing arm (in the case of a right handed person, the right arm) in close to the body while swinging with both arms, lowering the shoulder of the trailing arm, stepping slightly forward with the lead foot, and pushing off the trailing foot. By having the hands oriented about 90 degrees from each other (especially with a “split grip”), the trailing arm is kept in close to the body as both arms power the swing to generate power.
Due at least in part to the configuration of the front face 164, in order to hit the ball at the proper launch angle with the hands held in the indicated position on the handle area 142, the trailing shoulder can be lowered while pushing off the trailing leg. If the trailing shoulder is not sufficiently lowered, the front face 164 may be angled downward when contact is made with the ball. Thus, a user is provided feedback on how to adjust the swing. Conversely, if the trailing shoulder is lowered too much and the hands are in the indicated location, the ball may launch at too great a launch angle and the user is also provided feedback on how to adjust the swing. Accordingly, the hand placement indicators (relative to the front face 164) teach and enforce proper swing mechanics with the trailing arm kept close to the body and the trailing shoulder lowered.
Swinging with a conventional baseball bat or any swing training device with a round hitting face is less likely to teach and enforce proper swing mechanics in this way, especially if the user has not yet developed good aim with the bat and proper hand path. A baseball bat or training bat with a rounded hitting face can hit a ball at a different launch angle and direction depending on the aim of the bat because the rounded face causes the incident angle of contact to be different if the bat makes contact with the center of the bat (relative to the motion of the bat) or contacts above or below the center of the bat. Accordingly, a slight difference in aim may greatly affect the ball's launch angle and direction. It is difficult to develop proper aim when swing mechanics are not first developed and enforced. Accordingly, a flat hitting face (like that of front face 164) that is larger than the hitting surface on a standard bat is advantageous for developing proper swing mechanics while also developing aim.
Strength is often developed by swinging a heavy bat, however, if proper swing mechanics are not promoted while swinging the bat, improper swing mechanics are often developed. Also, the wrong muscles may be exercised by using the heavy bat if proper swing mechanics are not used. If too much weight is concentrated at the knob 120 end of the training bat 120 or concentrated at the hitting end (heading head 160 end) of the bat then the bat can swing differently and is less useful for developing proper swing mechanics and strength in the right muscles. For example, if too much weight is concentrated in the hitting end, a user may tend to lean back while swinging the bat causing the trailing arm to straighten out away from the body and the trailing hand to rotate around the handle to an improper position. Accordingly, a training bat with an appropriate weight distribution (added weight at the hitting end being offset with added weight at the knob 120 end) can help develop strength while also promoting proper swing mechanics.
The front face 164 (as a flat hitting face) may also be advantageous in helping users to practice aiming because the hitting/contact surface area may be larger than the hitting area of a standard baseball bat with a 2¼-2⅝ inch barrel. Trying to square up two round objects is very difficult. The greater area allows a user to practice swinging and aiming while having more balls being solidly contacted, increasing confidence and enforcing proper swing mechanics as aim is developed. A training bat with a significantly larger hitting area on the front face 164 (e.g., with a diameter of 5-6 inches) may be used to help a beginning user to develop aim and proper swing mechanics and a training bat 100 with a smaller hitting area (e.g., 2-3 inch diameter) on the flat front face 164 may be used as aim improves.
Training bat 100, 150, or 160 can be constructed and configured (e.g., with sufficient robust materials) for swinging practice without a ball, with a ball on a tee, or with a pitched ball. The location of the front face 164 in at or near the sweet spot (20-32 inches depending on size of bat) of a standard baseball bat allows a user to practice aiming for the sweet spot on the standard bat with a ball on a tee or a pitched ball. The training bat 100, 150, or 170 can also be used to train timing by swinging at pitched balls.
Further, it is advantageous to have the hitting head 160 include a rubber or other somewhat elastic material. These more elastic materials spread the force of impact from hitting the ball over a greater amount of time thus reducing or mitigating the chance of injury that the increased weight of the bat may cause. It is also advantageous to have the shaft 140 made of a hard material such as wood or metal that does not significantly flex at contact for durability and also to have the same feel in the hand when swung as a standard baseball bat. In some aspects, the shaft 140 and hitting head 160 are made of different materials (e.g, 140 of wood or metal and 160 of rubber).
In other aspects, hitting head 160 can be made of wood. For some users, youth or adults, having a hitting head 160 made of wood is advantageous because wood is less dense than rubber and most other similar elastic materials allowing for a larger hitting head for the same weight. At the speeds youth players swing, the risk of injury from swinging and making contact with the training bat 100 of an appropriate size are reduced, so a wood hitting head 160 can be appropriate without an increased risk of injury. Further, the wood hitting head 160 can provide contact and ball launch that is more similar to the feel of a standard baseball bat. Accordingly, with lower density, a hitting head 160 made of wood may be particularly advantageous for youth players.
Accordingly, the present description provides for various training bat embodiments. Many uses and advantages are offered by training bats 100, 150, or 170 as described above in one or more non-limiting embodiments in the present description.
As described, the training bats may include a shaft 140 and a hitting head 160. The shaft 140 may include a handle area 142 and hand placement indicators (for example, left hand palm indicator 122, right hand palm indicator 132, left hand finger indicators 124, right hand finger indicators 134, left hand thumb indicator 126, and right hand thumb indicator 136 and dial 138). The shaft 140 may include a first end and a second end opposite the first end. The hitting head 160 may be attached to the second end of the shaft 140. The hitting head 160 may include a front face 164 (e.g, a hitting surface) which is substantially flat and a back end (for example fallback face 162) opposite the front face 164. The hand placement indicators may indicate a position for at least one of the hands of a user on the handle and the hand placement indicators may indicate an alignment with the back end of the hitting head 160.
The training bat 100 may include a counterweight 110 attached to the first end of the shaft 140. The training bat 100 may further include a hand stop (e.g., knob 120) attached to the first end of the shaft 140. The counterweight 110 may attach to the first end of the shaft via the hand stop. The shaft 140 may increase in thickness in a first direction extending from the first end to the second end opposite the first end. The shaft 140 may further include a taper portion 144 at the second end and the handle area 142 is at the first end of the shaft, wherein the taper portion 144 is thicker than the handle area 142.
The hitting head 160 may be cylindrical in shape and includes the back face 162 (also flat) on the back end. The hand placement indicators may include a first alignment line (for example the center line in dial 138) aligned with the flat back surface 162. The hand placement indicators may include a pair of second alignment lines (for example side lines in dial 138) on either side of the alignment line. The pair of second alignment lines may be smaller than the first alignment line in at least one dimension (e.g., thickness or length). The pair of second alignment lines may be equidistant to the first alignment line.
Many different embodiments of the inventive concepts have been shown. A person of ordinary skill in the art will appreciate that the features from different embodiments may be combined or replaced with other features from different embodiments. Aspects of different embodiments can also be combined. As such, a training bat may include varied and different combinations of one or more of: hand palm indicator 122, right hand palm indicator 132, left hand finger indicators 124, right hand finger indicators 134, left hand thumb indicator 126, right hand thumb indicator 136, and dial 138. For example, a training bat may include left hand thumb indicator 126, right hand thumb indicator 136, and dial 138. Other combinations of indicators are also possible. Adjustable or fixed hitting heads can also be used with any of the varied and different combinations of indicators.
