Description

WO 01/10515 PCTIUSOO/20503 BALL HITTING PRACTICE APPARATUS Background of the Invention Ball hitting practice devices that suspend balls from ropes mounted to horizontal support members 5 are known. For example, Malwitz U.S. Patent No. 5,271,618 shows a batting practice device that includes a horizontally extending metal pipe from which a ball is suspended with a rope. The rope passes through a central aperture of the ball. A knot is 10 formed at the end of the rope that holds the ball on the rope. In another example, Rabine U.S. Patent No. 5,624,113 shows a portable batting system that can be attached to a chain link fence. Additional systems that suspend balls from ropes mounted to horizontal 15 support members are shown, for example, in Lunsford U.S. Patent 5,184,816, Smith U.S. Patent No. 5,454,561, Ring U.S. Patent No. 5,683,315, Espinosa et al. U.S. Patent No. 5,743,820, and Grimes U.S. Patent No. 5,836,836. 20 In each of the above-identified systems, however, it is difficult to cause the ball, which is suspended at the end of a flexible rope, to consistently pass through or over the same area. Other known ball practice devices attach 25 balls to rigid members. For example, U.S. Patent WO 01/10515 PCT/USOO/20503 -2 No. 5,833,555 shows a gravitationally restored ball practice device and Shieh U.S. Patent No. 5,700,203 shows a golf training device that uses a "dummy ball assembly." In these systems, although the ball is 5 required to pass through the same path, the ball does not simulate the natural motion of a free or tethered ball. Some known devices suspend balls from ropes and tubes. For example, Corley U.S. Patent 10 No. 5,531,438 shows a batting practice device that includes a ball tethered at the end of a rope and a soft plastic tube that covers a portion of the rope immediately above the ball. In another example, Kregel U.S. Patent No. 5,338,026 shows a swing training unit 15 that includes a tethered ball mounted beneath a basketball hoop. Although both references suspend a ball using a rope and a tube, the ball does not consistently move through the same or similar path. Finally, Scher et al. U.S. Patent 20 No. 5,374,056 shows a baseball practice device that suspends a ball from a "Y" shaped tether system that is itself supported by two horizontal arms that are also arranged in a "Y" shaped configuration. Unfortunately, the "Y" shaped tether system is visually distracting 25 and mechanically complicated and the "Y" shaped arms can add substantial weight to the upper portion of the device, potentially destabilizing it. It would therefore be desirable to provide a ball hitting practice device that is capable of 30 consistently delivering a ball through the same or similar path. It would also be desirable to provide a ball hitting practice device that is capable of consistently WO 01/10515 PCT/USOO/20503 -3 delivering a ball to a user in a smooth and natural manner. It would further be desirable to provide a ball hitting practice device that is capable of 5 consistently simulating a number of different types of pitches. It would additionally be desirable to provide a stable ball hitting practice device that is simple to make and use. 10 It would still be more desirable to provide a ball hitting practice device that includes a ball mounting assembly, which can be releasable. Summary of the Invention It is therefore an object of this invention 15 to provide a ball hitting practice device that is capable of consistently delivering a ball through the same or similar path. It is also an object of this invention to provide a ball hitting practice device that is capable 20 of consistently delivering a ball to a user in a smooth and natural manner. It is a further object of this invention to provide a ball hitting practice device that is capable of consistently simulating a number of different types 25 of pitches. It is yet another object of this invention to provide a stable ball hitting practice device that is simple to make and use and that is not visually distracting. 30 It is still another object of this invention to provide a ball hitting practice device that includes a ball mounting assembly that can be releasable.

FIG. 12 is a cross-sectional view of an illustrative lower end of a substantially rigid member according to this invention. Detailed Description of the Invention 15 In order that the invention herein described may be fully understood, the following detailed description is set forth. FIG. 1 shows ball hitting practice apparatus 10 according to this invention. Apparatus 10 20 at least includes (1) substantially rigid member 15 having first end 17 and second end 19, (2) hinge 20 attached at or near first end 17 such that second end 19 rotates about a substantially horizontal axis, and (3) ball mounting assembly 25. Preferably, second 25 end 19 rotates in a substantially vertical plane. Most preferably, member 15 is elongated and rotates in a substantially vertical plane. It will be appreciated that member 15 can also have a shape that is not elongated, such as an "L" shape, as long as that shape 30 is capable of rotation about a substantially horizontal axis.

WO 01/10515 PCTIUSOO/20503 -7 Ball mounting assembly 25 includes tether 30 and ball mounting device 29, which is suspended from tether 30. In one embodiment, member 15 is longer than assembly 25. As explained more fully below, ball 35 5 can be attached to assembly 25 in many different ways. A number of measures can be taken to help ensure smooth and natural ball motion while a ball is attached to ball mounting device 25. For example, as shown in FIG. 2, the substantially rigid member can be 10 made from two or more substantially rigid portions 16 and 18 connected by second hinge 21 so that each of portions 16 and 18 is capable of movement with respect to the other. In one embodiment, as shown in FIG. 3, second hinge 21 permits motion only in, or parallel 15 with, the vertical plane already provided by hinge 20. In this case, hinge 21 can be a cylinder-and-socket type connector, which includes cylinder 27 and socket 29. Here, the cylinder only rotates about its longitudinal axis in the socket. This serves to 20 restrict rotation of the lower portion to a substantially vertical plane. The lower and upper portions can also be connected with one or more hooks. In another embodiment, second hinge 21 is a ball-and socket type connector that permits rotation in and out 25 of the vertical plane defined by the first hinge. Natural motion of the ball can also be improved when the substantially rigid member weighs less than the weight of the combination of the ball mounting assembly and a ball attached to the assembly. 30 Preferably, the combination of the substantially rigid member, the ball mounting assembly, and the ball (when attached to the assembly) has a center of gravity that is below the substantially rigid member's lower end.

WO 01/10515 PCT/USOO/20503 -8 As shown in FIG. 1, for example, apparatus 10 can also include frame 40 for attaching hinge 20. In one embodiment, frame 40 includes substantially horizontal support structure 50 onto which hinge 20 is 5 secured. Apparatus 10 can also include substantially vertical support structure 60 for supporting structure 50. Structure 60 has upper end 62 and lower end 64. In this case, end 52 of horizontal structure 50 can be secured at or near end 62 of 10 vertical structure 60 and hinge 20 can be secured at or near end 54 of horizontal structure 50. Frame 40 can also include base 70 for supporting vertical structure 60. It will be appreciated that any of 15 substantially horizontal and substantially vertical structures 50 and 60 can be made from a single component, or from two or more components. It will be further appreciated that these components need not be oriented in the same direction. For example, as shown 20 in FIG. 1, substantially horizontal support structure 50 actually includes components 55, 56, and 57. Base 70 can be located in or near the substantially vertical plane of rotation. As shown in 25 FIG. 3a, for example, base 70 can include two or more legs 72 (which may be collapsible). When used for baseball practice, base 70 can be placed behind home plate so that apparatus 10 can be used easily by both left and right handed hitters. Other types of bases 30 can also be used, including water or sand filled bases. Both support structures 50 and 60 can have adjustable lengths to accommodate different user heights. As shown in FIG. 1, for example, these WO 01/10515 PCTIUSOO/20503 -9 structures can be telescopically connected. Locking hardware, such as pins and/or mechanical belts or collars, can be used to secure the lengths of the telescopic structures. As shown in FIG. 3b, for 5 example, vertical support structure 60 includes locking structure 65, which rotates about pivot 66 and is insertable through outer component 67 via aperture 68 for engaging inner component 69. Adjustable collar 63 can also be used to tighten the coupling between inner 10 and outer structural components 67 and 69 for the purpose of preventing wobble therebetween. Ball mounting assembly 25 includes ball mounting device 29, but can additionally include one or more components, such as tether 30. Tether 30 could 15 have an adjustable length, using a variable length loop, adjustable with any convenient fixing means, including a cord latch or simply knot 32. Ball mounting assembly 25 is suspended from lower end 19 of member 15. 20 FIG. 4 shows illustrative ball mounting device 70, which includes vertically suspended tube 72, plurality of shafts 74 that extend somewhat horizontally, and plurality of tubular members 76, which are supported by shafts 74. Preferably, 25 members 76 are adapted to rotate around each of shafts 74. Tubular members 76 can allow for releasable mounting of ball 80. Shafts 74 can be made from any material that is sufficiently stiff to support tubular member 76. Preferably, shafts 74 allow rotation of 30 tubular member 76, such as a rope (e.g., made from nylon) or a rod. As shown in FIG. 4, the same rope can be inserted through tube 72 to form loop 73 for attachment to tether 90.

WO 01/10515 PCT/USOO/20503 - 10 To facilitate releasable mounting of ball 80, a releasable fastener can be used between device 70 and ball 80. The fastener can include two complementary halves 78 and 79. First half 78 is fixed to tubular 5 member 76 and second half 79 is fixed to ball 80. One fastener of this type is a hook-and-loop type fastener (commonly referred to as VELCRO@), with the hook portion preferably attached to device 70 and the loop portion attached to ball 80. A portion of tubular 10 member 76 can be made concave for increasing contact surface between the two fastener halves. Preferably, tubular member 76 or any other part of device 70 (including entire device 70) can be replaceable. FIG. 5 shows another illustrative releasable 15 ball mounting device 100. Device 100 includes at least one cup 102 that is secured to tubular member 104. In this embodiment, cup 102 is used instead of a tubular member with a concave portion. Tubular member 104 can be suspended by substantially horizontal shaft 103, 20 which can be part of a larger support structure, such as triangular structure 105. Structure 105 need not be triangular, but should be capable of suspending member 104, preferably in a substantially horizontal manner. Tubular member 104 can optionally be rotatable 25 about shaft 103. Cup 102 preferably has an inner radius of curvature that substantially matches the outer radius of curvature of ball 120. The concave shape of cup 102 serves to increase contact surface area with ball 120. 30 A releasable fastener is used to facilitate attachment of cup 102 to ball 120. Preferably, the fastener has two halves. First half 106 is fixed to inner surface of cup 102 and second half 108 is fixed to ball 120.

WO 01/10515 PCT/USOO/20503 - 11 One fastener of this type is a hook-and-loop type fastener (i.e., VELCRO®), with the hook portion preferably attached to device cup 102 and the loop portion attached to ball 120. 5 It will be appreciated that a releasable fastener need not be provided on the inside of cup 102 and to the surface of ball 120. Rather, cup 102 can be releasably attached to ball 120 using suction. In this case, cup 102 preferably attaches to a substantially 10 smooth surface of ball 120. When suction is formed between the cup and the ball, the ball will be held in place. When the ball is hit, the suction is terminated and the ball is released. FIG. 6 shows another type of ball mounting 15 device that includes a different type of releasable fastener. Ball mounting device 130 includes a releasable fastener that itself includes piercing half 132 and pierceable half 134. Piercing half 132 is preferably attached to lower end 136 of ball mounting 20 device 130 and pierceable half 134 to ball 140. Piercing half 132, which is buried in pierceable half 134 in FIG. 6, includes at least one pointed member (e.g. a spike). Pierceable half is preferably made from a penetrable material, such as rubber, that 25 can withstand multiple pierces. When the spike pierces the rubber, it will be held there until the ball is hit by a hitting device, such as a bat. It will be appreciated that the piercing half need not be used with a shaft and rotatable tubular member as 30 described above. Rather, the piercing half need only be suspended from the ball mounting device, such as shown in FIG. 6.

WO 01/10515 PCT/USOO/20503 - 12 A substantially rigid member according to this invention can be a rod made from a material that is preferably lightweight, substantially rigid, and/or soft. Materials that can be used to construct the 5 substantially rigid member include, for example, foam, aluminum, plastic, rubber, or the like. Moreover, a combination of such materials can also be used. For example, the substantially rigid member may include an aluminum rod surrounded by foam, rubber, or any other 10 soft material to prevent injury. Also, the substantially rigid member can have a length that is adjustable. FIG. 7 is an enlarged partial front elevational view of ball hitting practice apparatus 10, 15 showing, in particular, hinge 20. Hinge 20 is preferably fixed near end 54 of horizontal structure 50 and to upper end 17 of member 15 such that member 15 is guided in substantially vertical plane 11. As shown best in FIG. 8, hinge 20 can include pin 24 (shaft-like 20 member) having substantially horizontal longitudinal axis 23 about which bottom part 22 can rotate. This ensures that member 15, which is attached to bottom part 22, rotates substantially in vertical plane 11. Upper part 26 can either be integrated with 25 structure 50 or secured thereto. FIG. 9 also shows hinge 20 and structure 50 from above. It will be appreciated that hinge 20 can be anything that substantially limits rotation of member 15 about a substantially horizontal axis. 30 Hinge 20 can be constructed to provide member 15 limited motion out of vertical plane 11 as well. For example, a spring element (not shown) can be attached between hinge 20 and member 15 or within WO 01/10515 PCT/USOO/20503 - 13 bottom part 22 itself. Such out-of-plane motion may be desirable to prevent injury if a person bumps into member 15 in a direction that is out of vertical plane 11. 5 Also, hinge 20 is preferably lightweight. Thus, hinge 20 should be small and preferably made with a lightweight material, such as plastic. To reduce the weight of hinge 20 further, passages can be molded into or bored from any part of hinge 20. For example, 10 bottom part 22 include passages 28. As shown best in FIG. 8, member 15 can be inserted into one of passages 28 and secured with set screw 31 or the like. FIG. 10 shows another embodiment of a ball hitting practice apparatus according to this invention. 15 Apparatus 150 includes a different type of hinge than the one shown in FIG. 1. In this case, horizontal support structure 170 (e.g., a horizontal bar of a children's swing set) acts as one half of the hinge and collar 180, to which member 190 is attached, is 20 rotatably mounted on horizontal support structure 170. FIG. 11 shows a magnified side view of the region surrounding hinge 160. As already described above, apparatus 150 also includes ball mounting assembly 192, which 25 includes tether 194 and ball mounting device 196. Tether can be any elongated flexible component that is suspendable from the bottom of member 190, from which ball mounting device 196 can be suspended. In one embodiment, tether 194 is adjustable in length and can 30 be made from an elastic or inelastic string or rope. As shown in FIG. 10, member 190 rotates in substantially vertical plane 198. It will be appreciated, however, that only the lower end of WO 01/10515 PCT/USOO/20503 - 14 member 190 (where ball mounting assembly 192 is attached) can rotate in a vertical plane. For example, as shown in dashed relief in FIG. 10, member 190 can be mounted to hinge 160 at an angle. In this case, only 5 the lower end of member 190 rotates in substantially vertical plane 199. It will be appreciated that any substantially rigid member according to this invention can be mounted in a similar fashion. A ball mounting assembly according to this 10 invention can be of the releasable type. As shown in FIGS. 4-6, for example, a ball mounting assembly can include a tether suspended from the lower split end of the substantially rigid member and a ball mounting device suspended from the tether. As also shown by 15 these FIGS., the tether can have an upper end with a releasable object, such as a bead, attached thereto. The lower split end of the rigid member can have a longitudinal passage adapted to hold the object until the tether has a tension greater than a threshold 20 tension. When the threshold tension is reached, the object will slip through the passage. Because the tether can detach from the substantially rigid member, the apparatus is safer than non-detachable practice devices. For example, if a 25 batter swings into the tether and entangles his bat, the detachable feature ensures that the frame does not topple and that the batter does not otherwise injure himself. It will be appreciated that the threshold 30 tension is determined, at least in part, by the amount that the substantially rigid member must flex before the object can slip out. Thus, the threshold can be decreased by increasing the size of the passage, the WO 01/10515 PCT/USOO/20503 - 15 rigidity of the substantially rigid member, or decreasing the friction between the object and the passage. As also shown in FIGS. 4-6, split end 205 can 5 be formed by forming longitudinal slot 207 at the end of a standard tube. Alternatively, split end 205, or entire rigid member 200, can be formed using any conventional molding technique. Longitudinal slot 207 preferably has a thickness that is less than the 10 diameter of bead 230 to prevent bead 230 from falling out from end 205. The upper end of longitudinal slot 207, however, has a thickness that is greater than the diameter of bead 230 to allow manual insertion or removal of bead 230 from end 205. 15 FIG. 12 shows a cross-sectional view of illustrative lower end 205 of substantially rigid member 200 with hollow plug 240 attached to end 205 and upper end 210 of tether 220 with bead 230 attached to end 210. As described above, member 200 can be made 20 from a material such as foam, aluminum, plastic, rubber, or the like. Hollow plug 240 can also be made from any of these materials. One suitable plastic material is sold by E.I. Du Pont de Nemours and Company, of Wilmington, Delaware, under the trademark 25 DELRIN@. Plug 240 can be attached to end 205 by any convenient means, including glue 250 or a set screw (not shown). As shown in FIG. 12, the upper surface of plug 240 is sloped to center bead 230 at the upper end 30 of bead passage 270. It will be appreciated that plug 240 is two unattached semi-annular pieces, each of which is attached to opposite inner surfaces of end 205. Because these pieces are unattached, they can WO 01/10515 PCT/USOO/20503 - 16 separate when bead 230 is pulled in a downward direction from the position shown in FIG. 12. Bead 230 can be fixed to upper end 210 of tether 220 by threading end 210 through bead 230 as 5 shown in FIG. 12. Alternatively, bead 230 and tether 220 can be formed from a single material. It will be appreciated, however, that tether 220 could be suspended with any object, including a non-spherical object. When bead 230 is used, tip 260 of tether 220 10 is preferably thick enough such that tip 260 does not slip through bead 230, even when tension is applied to tether 220. It will be appreciated that member 200 can be integral with tether 220. For example, member 200 and 15 tether 220 can be made from a rope, where the upper portion that forms member 200 is hardened. For example, a nylon rope can be hardened by coating it or impregnated with a resin (or by heating it), while the lower portion is left flexible. In this way, the hinge 20 between member 200 and tether 220 is simply the transitional region therebetween. In this case, member 200 and tether 220 may not be detachable. A method for practicing hitting a ball is also provided. The method includes providing a ball 25 hitting practice apparatus that includes a ball mounting device, mounting a ball on the ball mounting device, positioning the ball at a preferred height, allowing the ball to fall while attached to the ball mounting device, and hitting the ball with a hitting 30 device. The ball hitting practice apparatus can be any of the embodiments shown or discussed above. Preferably, when the ball is hit with sufficient force, the ball will detach from the ball mounting device as WO 01/10515 PCT/USOO/20503 - 17 also discussed above. Hitting devices that can be used according to this invention include, but are not limited to, a bat, a club, a racket, a stick, a bare hand, and a gloved hand. 5 The ball should be positioned correctly during use of the apparatus. For example, when the ball is positioned correctly, the ball should be able to fall, causing the substantially rigid member to rotate on a hinge about a substantially horizontal 10 axis. As explained above, the lower end of the member preferably moves in a substantially vertical plane. In one embodiment, the ball can be positioned by raising the ball to a user-determined height. When the height is substantially above the lowest point 15 along its path, the ball can fall under the force of gravity and pass that point (e.g., directly above or in front of home plate) along its arc at a high speed. When the ball is not raised to a lower height, the ball will pass that point at a lower speed. In this way, 20 the speed of the ball passing the lowest point on the ball's arc can be adjusted. It will be appreciated that the ball can also be raised with an automated device, driven by an electric motor, or by any number of non-automated devices. 25 An advantage of the present invention is that a ball attached to the ball mounting device can be made to travel in a substantially consistent fashion -- in or out of the vertical plane, but limited by the path of the substantially rigid member, which is preferably 30 elongated. For example, if the ball is raised to a height in the vertical plane of the apparatus and then dropped, the motion of the ball during its swing will be primarily in-plane. However, if the ball is raised WO 01/10515 PCT/USOO/20503 - 18 to the same position and then pushed in a direction that is out-of-plane, the motion of the ball will include out-of-plane motion. Alternatively, the ball can also be raised and released at a position outside 5 the vertical plane. Thus, it will be appreciated that when the apparatus is used to practice hitting a baseball, a number of different types of pitches (e.g., curve, outside, inside, etc.) can be simulated consistently with the apparatus. 10 The combination of the substantially rigid member and the upper hinge is believed to be at least partially responsible for the ability of the apparatus to provide consistent yet variable simulations. This appears to be especially true when the substantially 15 rigid member is longer than the ball mounting assembly. When at least one of the substantially vertical and horizontal support structures has a length that is adjustable, the method can further include adjusting that length to adapt the apparatus to the 20 practicing hitter. Similarly, when the ball mounting assembly includes a ball mounting device and a tether with an adjustable length, the method can further include adjusting the tether to a length to suit the practicing hitter. 25 Thus, it is seen that apparatus and methods are provided that can be used to practice hitting a ball. One skilled in the art will appreciate that the present invention can be practiced by other than the described embodiments, which are presented for purposes 30 of illustration only and not by way of limitation, and the present invention is limited only by the claims that follow.
