DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION
(17) Referring to
(18) The strike target 18 may be integrated with the distal end 14 of swing arm 12 or may be re-attachably detachable (reconnectably disconnectable) from the distal end 14 of the swing arm 12. For example, the strike target 18 may be connected to the distal end 14 of the swing arm 12 with a screw 20 or the like fastener.
(19) A batting tee according to the present invention includes a damped return mechanism 22. The damped return mechanism 22 includes a rotatable axle 24 (see
(20) In the preferred embodiment, the swing arm 12 may be a straight elongated body (for example, a tube or a rod) having a longitudinal axis which is normal to the longitudinal axis of the rotatable axle 24 when the swing arm 12 is connected to the rotatable axle 24.
(21) In the first embodiment, the swing arm 12 has a fixed length.
(22) Preferably, the return mechanism 22 is supported on a stand 26. Stand 26 may include a base 28. Referring to
(23) In the preferred embodiment, each socket 32 is located between two other adjacent sockets 32, and angularly spaced from one of the two adjacently located sockets 32 by a first angle and angularly spaced from the other of the two adjacently located sockets 32 by another angle , which is larger than the first angle.
(24) Each socket 32 receives therein and may be fixed to an end portion of a respective spoke 34. Each spoke 34 may be an elongated tube. The opposite end of each spoke 34 may have a foot 37 or the like mounted thereon. Thus, spokes 34, when fixed to sockets 32, extend radially away from a central point of hub 30, and the feet 37 are arranged at four corners of an imaginary rectangle, whereby more support can be provided to resist tipping over in the direction of the strike than a direction transverse to the direction of the strike when the strike target 18 is stricken by a bat.
(25) A central socket 36, which is preferably aligned with the central axis of the central support hub 30, extends in a direction that is normal to the central, longitudinal axes of all sockets 32. An end portion of a support pole 38 is received in the central socket 36. The support pole 38 is preferably a cylindrical tube. A telescopic support arm 40 (which may be a tube or a rod) is received inside of the support pole 38 and can move along the central, longitudinal axis of the support pole 38 relative to the support pole 38 in a telescopic fashion, whereby the distance between the top end of the support arm 40 and the top end of the support pole 38 can be varied to set the height of the strike target 18 relative to the ground.
(26) A plurality of spaced holes 42 may be longitudinally arranged along the body of the support pole 38. A spring loaded plunger pin (not shown) or the like may be integrated with the support arm 40 and arranged to be received inside of a hole 42, whereby the support arm 40 can be fixed in position relative to the support pole 38.
(27) Alternatively, instead of a spring loaded plunger pin, a screw or the like may be used to fix the support arm 40 in position relative to the support pole 38. In this way, the height of the top end of the support arm 40 can be adjusted selectively.
(28) It should be noted that the mechanism described herein for setting the height of the top end of the support arm 40 is not critical, and any other suitable mechanism can be used without deviating from the invention. For example, Huang (US 2007/0049426) discloses a screw to set the height of a telescopic arm, which could be used to set the height in a tee according to the present invention.
(29) According to one aspect of the present invention, the spokes 34 are fixed to sockets 32 with a selectively releasable device such as a spring loaded plunger pin, whereby the spokes 34 can be assembled or disassembled with relative ease. That is, the spokes 34 may be re-attachably detachable (disconnectably reconnectable) to sockets 32.
(30) Similarly, support pole 38 may be fixed to central socket 36 with a releasable device such as a spring loaded plunger pin, whereby support pole 38 may be assembled or disassembled with relative ease. That is, the support pole 38 may be re-attachably detachable (disconnectably reconnectable) to the central socket 36.
(31) Through re-attachability (reconnectability) of its parts after disassembly, a batting tee according to the first embodiment, can be disassembled so that it may be transported easily from one location to another location in a disassembled state, and then assembled easily at the another location. Other devices such as screws may be used to permit re-assemblity after disassembly.
(32) Referring now to
(33) Axle 24 includes a central lug 52 located between its first end portion and its second end portion. Central lug 52 includes a threaded opening 54 therein, which may be a blind hole, having a central axis that is normal to the longitudinal axis (rotation axis) of axle 24. The first part 44 and the second part 44 are preferably integrated with screws or the like in order to support axle 24 in chamber 46. Once the first part 44 and the second part 44 are assembled, a gap 56 is defined which allows unobstructed access to the chamber 54 and the central lug 52.
(34) The return mechanism 22 includes a mechanical energy storage device, which in the preferred embodiment may be at least one torsion spring. The mechanical energy storage device stores the energy of the strike, which stored energy generates the force to return the strike object to its original position after it is stricken.
(35) Thus, in the first embodiment, a first torsion spring 58 is disposed around the axle 24 and located between its first end portion and central lug 52. A second torsion spring 60 is disposed around the axle 24 and located between the central lug 52 and the second end portion of the axle 24. Each torsion spring 58,60 is arranged so that rotation of the axle 24 in one direction (example clockwise) results in the storing of mechanical energy in the torsion springs 58, 60 (i.e. the loading of the torsion springs), which stored energy can then be used to rotate the axle 24 in the opposite direction (e.g. counterclockwise).
(36) According to the present invention, at least the counter rotation of the axle 24 (i.e. its rotation after the torsion springs are loaded) is damped. In order to implement the damping, in the preferred embodiment, a damper 62 is connected to the axle 24. The damper 62 may be a rotary damper or a torque damper.
(37) In the preferred embodiment, the second rotating end portion of the axle 24 includes an extension 64, which is in axial alignment with the central, longitudinal axis of the axle 24 about which the axle 24 rotates. The extension 64 extends out of the housing 44 and is connected to the damper 62. The damper 62 may be mounted to the exterior surface of the second part 44 of the housing 44. Through its connection to the damper 62, at least the counter rotation of the axle 24 is damped and thus slowed down. The damping slows down the swinging of the swing arm 12 under the force supplied by the loaded torsion springs.
(38) The damper 62 may be selected to damp/absorb some of the energy of the strike in order to slow down the loading of the torsion springs 58, 60 (and the swinging of the swing arm 12) and provide some resistance to the strike, thereby creating the sensation of hitting a moving ball for the batter.
(39) According to the present invention, the torsion springs 58,60 and the damper 62 are selected so that it takes at least one second and preferably no more than six seconds for the swing arm 12 to return to its original, standby position (before the strike and before the loading of the torsion springs 58,60 begins) from a deflected position which is at a ninety degree angular displacement relative to the original, standby position of the swing arm 12. That is, the damped swing arm 12 that is damped by damper 62 swings back to its standby position at an average speed in the range of fifteen degrees per second to ninety degrees per second. The slower rate of return (average speed) of the swing arm 12 from the deflected position to the standby position may be useful for training younger batters (e.g. ages 6-8) by providing more time to the batter to take a proper stance and coordinate.
(40) It should be noted that the swing arm 12 may be deflected more than ninety degrees from its standby position (up to one hundred eighty degrees in the first embodiment) depending on the force of the strike received by the strike target 18. The average speed of the damped swing arm 12 should not be interpreted to mean that the range of motion of the swing arm 12 is limited to ninety degrees.
(41) The damper 62 may have a preset damping constant to set the speed, or may be adjustable so that the rate of return of the swing arm 12 can be selected/set by the user or the trainer. Thus, a tee according to the present invention may have a damper 62 that is adjustable to damp the motion of the swing arm 12 from a deflected position to the standby position so that the return speed of the damped swing arm 12 from the deflected position to the standby position can be set in the range of fifteen degrees per second to ninety degrees per second.
(42) In the preferred embodiment, the standby position of the swing arm 12 is vertical relative to the horizon, and the ninety degree angle referred to herein is parallel to the horizon.
(43) In the preferred embodiment, the housing 44 may include an integrated collar 66, which is sized to fit around the support arm 40 whereby the housing 44 and the return mechanism 22 can be secured to the support arm 40, with a screw or the like to tighten the grip of the collar around the support arm 40. It should be noted that the collar 66 is located lateral to the chamber 46 in the embodiment disclosed herein. Instead of positioning the collar 66 lateral to the chamber 46, the collar 66 or a socket could be positioned below the chamber 46.
(44) The swing arm 12 include a threaded exterior end located at its proximal end portion (
(45) Referring to
(46) It should be noted that, while preferred, it is not necessary to provide a bore 68 that passes through the center of the strike target 18. For example, as an alternative, a screw or the like could be mounted to the distal end of the swing arm 12, and the strike target 18 could be provided with a threaded opening to couple to the screw at the distal end 14 of the swing arm 12 without deviating from the present invention.

(49) Referring to
(50) The swing pole 82 includes a cylindrical receptacle portion 88 that receives a proximal end portion of the telescopic swing arm 12 and is fixed thereto preferably with a releasable device or a screw to permit selective assembly and disassembly of the swing arm 12. The swing pole 82 further includes two lobes 90, which are integrated with and extend from the exterior surface of the cylindrical receptacle portion 88.
(51) Preferably, the cylindrical receptacle portion 88 and the lobes 90 are integrated to define a unitary body. Each lobe 90 includes a through opening 92 therein that is sized and shaped to receive a respective end portion of the axle 25. Each lobe 90 is then connected with a screw or the like fastener to the axle 25, whereby the swing pole 82 is permitted to swing about the central longitudinal axis of the axle 25 to store energy in the spring portions 78 (i.e. to load the spring portions 78), when the swing arm 12 swings due, for example, to the striking of the strike target 18 by the batter.
(52) The axle 25 also includes an extension 70 which is connected to the damper 62 in order to provide at least a slow, damped return that takes at least one second but preferably no more than six seconds to return the swing arm to its original, standby position (e.g. the vertical, upright position) from a deflected position at a ninety degree displacement relative to the original, standby position. That is, the damped swing arm 12 returns from a deflected position to its standby position at an average speed in the range fifteen degrees per second to ninety degrees per second.
(53) Referring to
(54) Preferably, the screws used to mount the bracket 74 to the support plate 94 also pass through plate 86.
(55) A cover 96 (
(56) The cover 96 may be connected to the support plate 94, or may simply reside over the support plate 94 in order to maintain the tee 11 in place.
(57) The cover 96 may be made heavy in order to prevent the tee from tipping over.
(58) Optionally, a protective cover such as a foam padding or the like may be releasably attached to at least a part of the tee to provide protection against mis-swings by the batter. For example, a foam padding or the like may be slipped over the adjustable pole 38 and releasably secured around the pole with a strip of VELCRO (hook and loop fastener) or the like.
(59) Although the present invention has been described in relation to particular embodiments thereof, many other variations and modifications and other uses will become apparent to those skilled in the art. It is preferred, therefore, that the present invention be limited not by the specific disclosure herein, but only by the appended claims.
