The following includes information that may be useful in understanding the present disclosure. It is not an admission that any of the information provided herein is prior art nor material to the presently described or claimed inventions, nor that any publication or document that is specifically or implicitly referenced is prior art.
The present invention relates generally to the field of practice or training devices and more specifically relates to practice or training devices utilizing projectiles suspended by a tether.
Success in many sports requires precise control of a racquet, bat, or club when striking a ball or other sports object. Although game play within the above-noted sports is highly diverse, there are significant similarities in the means by which player skill is achieved within these sports. Isolating and practicing particular movements of play has many benefits. For example, placing a tennis ball, volley ball, badminton shuttlecock, racquet ball or squash ball at an ideal service location enables the server to improve their service techniques. This is particularly important because it separates the two major causes of variation, the toss variation and the service motion variation. When the object is in the ideal service location, a player can focus on improving the service motion without chasing a poorly tossed ball or object of play. Thus a need exists for new practice systems that achieve this objective.
Prior attempts have been made to address this need. For example, U.S. Pat. No./Pub. No. 7,691,013 to Emerson relates to a method and device for tennis training. The described method and device for tennis training includes a tennis training device comprises a ball, a rope, and a hollow pole, the ball being coupled with a portion of a first end of the rope, a part of the rope being in a cavity of the pole, the rope being knotted at or near the second end of the rope. The training device may be coupled with a support. A method of training various tennis shots comprises the steps of obtaining the training device; adjusting a length of a first portion of the rope which is outside the pole between an first end of the pole and the first end of the rope; holding the pole to set the ball at a selected height; and allowing a player to hit the ball with a tennis racquet. Multiple trainers may participate the training with the training devices and allow a player to practice a combination of different tennis shots. Unfortunately, the apparatus of Emerson is deficient in that the ball is fixedly attached to the line in a tethered fashion wherein the ball stays attached to the line after it is hit, thus limiting the effectiveness of the apparatus as a training device.
In view of the foregoing disadvantages inherent in the known practice or training devices art, the present disclosure provides a novel sports training system and method. The general purpose of the present disclosure, which will be described subsequently in greater detail, is to provide a sport training system related to improving the ability of a player to strike a sports object such as a ball, shuttlecock, etc.
A sport training system is disclosed herein. The sport training system may include a support frame, including a substantially vertical support member that may have an upper end and a lower end, an overhead support member that may include a distal end, a proximal end, and an elongated middle segment extending between the distal end and the proximal end. The proximal end may be coupled to the upper end of the substantially vertical support member. The elongated middle segment may project outwardly from the connection point. A base member may be provided, which may be coupled to the lower end of the substantially vertical support member. Such a base may be configured to support the substantially vertical support member from a ground surface. A cord movably engaged with the overhead support member may be also be provided. The cord may have a first end suspended below the distal end of the overhead support member and a second end suspended below the proximal end of the overhead support member. A releasable attacher may be provided at the first end. The releasable attacher may be configured to attach the sports object to the first end of the cord and to release the sports object from the cord when the sports object is struck by the player.
A first height adjuster configured to allow a user to adjust the height of the sports object relative to the ground surface may be provided. Such a first height adjuster may include a counter weight coupled to the second end of the cord, wherein the height of the sports object is adjustable by user positioning of the counter weight relative to the proximal end of the overhead support member. Such adjustment functions to alter the length of the cord between the releasable attacher and the distal end of the overhead support member. In turn, the height of the first height adjuster and any sports object attached to the first height adjuster, is raised or lowered relative to the ground surface. Additional height and angle adjustment features may be provided, as disclosed herein.
A method of using the sport training system is also disclosed herein. The method of using the sport training system may comprise the steps of: providing a support frame including a substantially vertical support member may have an upper end and a lower end, an overhead support member may have a distal end, a proximal end, and an elongated middle segment extending between the distal end and the proximal end, the proximal end coupled to the upper end of the substantially vertical support member, the elongated middle segment projecting outwardly thereof, and coupled to the lower end of the substantially vertical support member, a base member configured to support the substantially vertical support member from a ground surface; providing a cord movably engaged with the overhead support member, the cord may have a first end suspended below the distal end of the overhead support member and a second end suspended below the proximal end of the overhead support member; providing a releasable attacher configured to attach the sports object to the first end of the cord and to release the sports object from the cord when the sports object may be struck by the player; and providing a first height adjuster configured to allow a user to adjust the height of the sports object relative to the ground surface, the first height adjuster may include a counter weight coupled to the second end of the cord, the height of the sports object adjustable by user positioning of the counter weight relative to the proximal end of the overhead support member, such adjustment altering the length of the cord between the releasable attacher and the distal end of the overhead support member; attaching the sports object to the releasable attacher; and adjusting the height of the sports object to a user-selected height relative to the ground surface using the first height adjuster.
For purposes of summarizing the invention, certain aspects, advantages, and novel features of the invention have been described herein. It is to be understood that not necessarily all such advantages may be achieved in accordance with any one particular embodiment of the invention. Thus, the invention may be embodied or carried out in a manner that achieves or optimizes one advantage or group of advantages as taught herein without necessarily achieving other advantages as may be taught or suggested herein. The features of the invention which are believed to be novel are particularly pointed out and distinctly claimed in the concluding portion of the specification. These and other features, aspects, and advantages of the present invention will become better understood with reference to the following drawings and detailed description.
The figures which accompany the written portion of this specification illustrate embodiments and methods of use for the present disclosure, a sports training system and method, constructed and operative according to the teachings of the present disclosure.
The various embodiments of the present invention will hereinafter be described in conjunction with the appended drawings, wherein like designations denote like elements.
As discussed above, embodiments of the present disclosure relate to a practice or training devices and more particularly to a sports training system and method as used to improve the practice or training devices utilizing projectiles suspended by a tether.
Generally, the device suspends a tennis ball, badminton birdie (shuttlecock), volley ball, baseball, racquet ball, or squash ball in a selected three-dimensional location (x-axis is left to right from the user, y-axis is towards and away from the user, and vertical z-axis is up and down). The tennis ball, badminton birdie, volley ball, baseball, racquet ball, or squash will hereinafter be referred to generally as a “sports object”. Such sports objects include, but are not limited to the aforementioned items.
The disclosed device is a training aid designed to improve the tennis serves, ground strokes and volleys; badminton serves and strokes, volley ball serves and returns, baseball batting, racquet ball serves and returns, squash serves and returns. It is also useful in any activity where the user desires to improve striking performance when a sports object is suspended in a particular three-dimensional space location.
The placement of the tennis ball, badminton shuttlecock, volley ball, baseball, racquet ball, squash ball, or other sports object is easily adjustable to the desired three-dimensional location of the user.
The device is portable and can be used on the actual playing field: such as, but not limited to tennis courts, volley ball courts, baseball fields, racquet ball courts or squash courts.
When the suspended sports object is struck, the sports object retention force is very low and the sports object takes a trajectory, with any associated imparted spin, very similar to a free floating sports object being struck.
The device is free standing, self-supporting, portable, easy to set up, reload sports objects, and take down after use.
The device can use actual regulation tennis balls, badminton shuttlecocks, volley balls, baseballs, racquet balls, squash balls, or other sports objects.
The tennis balls, badminton shuttlecocks, volley balls, baseballs, racquet balls, squash balls, or other sports objects are loaded manually with an option for automatic loading.
The device utilizes a counter balance friction system to adjust and maintain the vertical (z-axis) placement of the sports object. A hook-and-loop fastener type attachment (for example, a Velcro® product) may be used to suspend the sports object and adjust height of the sports objects with a line. The x and y position are adjusted by placement of the base or rotation of the system.
The device allows a user to practice striking the sports object in a user-selected location. Examples in tennis include: striking high volleys, low volleys, high ground strokes, low ground strokes, low ground strokes close to the net, close to the body strokes, and overheads. The device also allows the user to practice striking a rising or descending sports object. In this case, the ball is released, such as by a coach, with the cord taut to the front side of the user (but not directly in front of the user). The ball will follow a pendulum motion and can be struck during the downward or upwards trajectory of the pendulum motion. The device may also be used in group training sessions.
The device provides a target for tossing the volley ball, badminton ball, racquet ball, squash ball, or other sports object during the service motion.
Placing the volley ball, badminton shuttlecock, racquet ball or squash ball at the ideal service location enables the server to improve his service techniques. This is particularly important because it separates the two major causes of variation: the toss variation and the service motion variation. When the sports object is the ideal service location the user can focus on improving the service motion without chasing a poorly tossed sports object.
The device is designed to mount cameras, video players, and/or radar guns, or other devices to help the user analyze and improve performance.
The device utilizes a mechanism to prevent the cord from wrapping around the overhead suspension pole. A weight is attached on the cord on a location above the sports object which is attached to hook-and-loop fastener. The durometer of the weight is sufficiently low to prevent damage to the striking object, such as a tennis racket, if the weight is accidently struck. The distance between the weight and the overhead pole is greater than the distance between the weight and the sports object which is attached to hook-and-loop fastener. As the sports object attached to hook-and-loop fastener is struck, the hook-and-loop fastener detaches from the sports object. The sports object takes the trajectory similar to a freely struck sports object. The hook-and-loop fastener rotates around the weight in a planetary motion. The weight and hook-and-loop fastener move in a circular planetary arch around the overhead pole. The inertial weight is high enough so that the weight and hook-and-loop fastener does not have enough momentum for the weight to circle the overhead pole. Thus, preventing cord entanglement around the overhead support member. The weight has a generally conical shape to help prevent cord entanglement around the weight.
Referring now more specifically to the drawings by numerals of reference, there is shown in
The sport training system 100 may further include an adjustable overhead support member 110 having a distal end 112, a proximal end 114, and an elongated middle segment 116 extending between the distal end 112 and the proximal end 114, as shown. The proximal end 114 may be pivotally coupled to the vertical support member 104 near the upper end 106, as shown in
The sport training system 100 may further include a base member 118 coupled to the lower end 108 of the vertical support member 104. The base member 118 is configured to support the vertical support member 104 from a ground surface 101. As noted above, the ground surface 101 may comprise an actual playing field, such as, for example, tennis courts, volley ball courts, baseball fields, racquet ball courts or squash courts, etc. The system may also be used on other non-play surfaces having relatively level topographies (i.e., parking lots, fields, etc.)
In one embodiment of the present system, the base member 118 includes at least three support legs 128 projecting outwardly from the vertical support member 104. The three support legs 128 may be configured to be foldable to positions located tightly adjacent the vertical support member 104, thus providing a compact form for transport and storage (see
The sport training system 100 may further include a releasable attacher 126 configured to attach the sports object 103 to the first end 122 of the cord 120 and to release the sports object 103 from the cord 120 when the sports object 103 is struck by the player. The releasable attacher 126 may utilize a hook-and-loop fastener material 166, such as Velcro® to join the sports object 103 to the end of the cord. The releasable attacher 126 may further include a resilient support disk 130 adapted to firmly support the hook-and-loop fastener material and couple the hook-and-loop fastener material with the cord 120. The diameter of the resilient support disk 130 may be selected to match the area of hook-and-loop fastener material 166 required to support the weight of the selected sports object 103. Through experimentation, it was found that a resilient support disk 130 formed from rubber having a shore-A hardness of between about 70 and 80 provided superior in-use durability. Upon reading this specification, it should be appreciated that, under appropriate circumstances, considering such issues as user preferences, design preference, structural requirements, marketing preferences, cost, available materials, technological advances, etc., other attachment arrangements such as, for example, temporary bonding materials, mechanical grips, releasable straps, slings, the use of harder or softer rubber materials, etc., may be sufficient.
The sport training system 100 may further include a mechanism to prevent the cord 120 from wrapping around the overhead support member 110. More specifically, the system may include an anti-cord-wrapping restrainer 132 configured to reduce wrapping movement of the cord 120 about the distal end 112 and adjacent portions of the overhead support member 110 after the sports object 103 is struck. In one embodiment of the present system, the cord-wrapping restrainer 132 may include a motion-dampening weight 134 affixed to the cord 120 at a position between the distal end 112 of the overhead support member 110 and the releasable attacher 126 (see
In specific reference to
The first height adjuster 140 may further include a first frictional retainer 144 configured to frictionally retain the position of the counter weight 142 and the object/releasable attacher 126 relative to the overhead support member 110. In one embodiment of the system, the overhead support member 110 comprises a rigid hollow tube having an internal cord passage 146 through which the cord 120 passes (see
By way of example, after a tennis ball is hit, the releasable attacher 126 often cannot be reached and pulled down for the next reload since it is located several feet above the user's fully extended hand. The counter-balance arrangements of the first height adjuster 140 enables convenient raising and lowering of the releasable attacher 126. Moreover, the position of the releasable attacher 126 and sports object 103 are held in place during use by the friction of the system. Therefore, there is no need to clip, tie, or otherwise attach the cord in place. The cord 120, along with the associated weight, stays in place whether the object to be struck is attached to the or not.
The friction utilized within the first height adjuster 140 is generally a function of:
a) the coefficient of friction of the overhead support member 110 and cord 120;
b) the mass/weight of the counter weight 142;
c) the mass/weight of the motion-dampening weight 134 and releasable attacher 126; and
d) the weight of the sports object 103, when the object is attached before striking; and
e) the ending weight of the assembly after the sports object 103 has been struck and detaches from system.
f) The friction may also be adjusted by mechanical means, such as clamping mechanism; lubricants; coating on the cord and/or support member; changing material surface finish, or other methods to adjust friction.
Again referring to the example of
The counter weight 142 may further include a counter-weight coupler 148 configured to assist user coupling and decoupling of the counter weight 142 and cord. The counter-weight coupler 148 may comprise a carabiner-style device supporting a set of disk-shaped weights (washers) having a central aperture. The user may fine-tune the performance of the first height adjuster 140 by adding or removing weights from the coupler. Upon reading this specification, it should be appreciated that, under appropriate circumstances, considering such issues as user preferences, design preference, structural requirements, marketing preferences, cost, available materials, technological advances, etc., other adjuster arrangements such as, for example, the use of other weight configurations, the use of cord ties, electrically-operated cord deployment reels, automatic object loaders, etc., may be sufficient.
Referring again to
The system may include additional useful accessories. In one implementation of the present system, the device may include one or more device mounts 162 adapted to removably mount at least one imaging device such as cameras, video players, radar guns, etc. The system may include a toss target device attachable to the releasable attacher 126. The toss target device may be used to practice the accuracy of an upward throw. The toss target device may include a hollow cylindrical tube having open upper and lower ends. A set of suspension cords may be included to allow the user to connect the upper end of the cylindrical tube to the releasable attacher 126. In use, the toss target device is suspended vertically above the user. The user attempts to toss a ball or other sports object 103 upwardly through the lower open end of the cylindrical tube. In this way, the accuracy of the user's throw may be improved. The support frame 102 may include safety accessories customarily used in heavy-duty supports stands, such as, for example, safety pins/receivers adapted to positively interlock the tubular members 113, etc. Embodiments of the sport training system 100 may be folded and arranged in compact form for transport and storage, as shown in
