This application claims the benefit of provisional patent application Ser. No. 62/006,047, filed on May 31, 2014 by a present inventor.
The present invention relates to a training device and method for teaching a user the proper execution of an athletic swing such as those used in baseball, softball, golf, tennis and the like. In particular, the present invention relates to a training device that teaches the proper timing and coordination of the user's body during the execution of an athletic swing such that optimal athletic results are achieved.
A seemingly countless number of devices designed to improve the performance of athletic swings have been patented in the history of athletic training. Of these devices a notable subset provide audible, visual or tactile feedback to the user pertaining to the proper timing of the execution of the swing being trained. Of this subset there is still an impressive quantity of patents pertaining to feedback provided by a moveable member propelled by the centrifugal acceleration of the swing along the axis of an elongated member striking a fixed implement attached to said member. Of such devices the following is a tabulation of some prior art that presently appears relevant:
While the feedback provided by the devices cited above is indeed valuable, these devises do not quantify the force or velocity of the swing being trained. Without this feedback the effectiveness of these devices is limited.
An additional subset of devices designed to improve the performance of athletic swings seek to quantify the velocity or force generated by the swing. This feedback can then be used by the user to improve the velocity or force of their swing. Of such devices, the following is a tabulation of some prior art that presently appears relevant:
Again, the feedback provided by these devices is indeed valuable, however these devices do not provide feedback pertaining to the point during the swing in which the maximum velocity or force is achieved. Without this feedback the effectiveness of these devices is limited.
A third, and most recent, subset of devices designed to improve the performance of athletic swings seeks to close the gap between the two subsets previously cited by providing both an audible, visual or tactile feedback to the user; and by attempting to quantify the velocity or force generated by the swing. Of such devices the following is a tabulation of some prior art that presently appears relevant:
The devices cited above provide an improvement over the previous two subsets, unfortunately these devices are also of limited effectiveness in that they require the user to configure the device prior to the execution of the swing. This effectively provides the user with only binary feedback pertaining to the velocity or force generated by any particular swing (i.e. if the swing does or does not meet or exceed the preconfigured velocity or force). Further, it is believed by this author that such binary feedback encourages the user to sacrifice form and tempo in the achievement of the pre-configured velocity or force. Because of this limited feedback the effectiveness of these devices is limited.
Of the prior art, the work of Sutlovich et al. in patent US 2010/0234144 A1, 2010 Sep. 16 is also noteworthy. This patent notes the importance of “making contact at the exact moment that the bat velocity reaches its maximum point,” however the device described in this patent does not quantify the velocity at the moment of impact.
Finally, the author also notes that none of the prior art specimens that can presently be identified provide a means of adjusting the starting position of the sliding members of their designs in order to allow for the training of multiple elements of an athletic swing.
The present invention relates to a training device and method for teaching a user the proper execution of various elements of an athletic swing such as those used in baseball, softball, golf and the like. The swing training device includes a shaft with a grip and a knob attached at one end. Along the axis of the shaft is a movable stop and a sliding member. The movable stop provides the ability to vary the starting position of the sliding member, providing for a variety of training methods to be performed that allow for focused training of the proper execution of specific elements of an athletic swing.
Movably held at the opposite end of the shaft is a force capture member comprised of; a cap, a force indicator, and a friction device. During the execution of a swing the centripetal acceleration generated by the swing causes the sliding member to travel down the shaft striking the force capture member producing an audible, tactile and visual feedback to said user and simulates the striking of an object. Further, the force capture member is displaced a distance proportional to the velocity of the sliding member and maintains this position until reset by the user. This allows the swing training device to quantify the force generated by the swing at the moment of impact for a wide range of results without the need for the device to be configured for a specific result prior to the execution the swing. Further, a means of retaining the sliding member in the starting position is provided that allows the swing training device to be used to train a multitude of athletic swings, particularly those performed on a vertical plain such as golf swings.
Contained within the shaft is a reset linkage that connects the force capture member to a restraining member comprised of; a reset grasp, and a retaining stop. The retaining member provides a means of restricting the displacement of the force capture member to a desired distance, and provides a means of quickly resetting the device for the execution of subsequent swing, thus maximizing training time. Training methods using the swing training device are provided that improve athletic performance, and allow for focused training of the proper execution of specific elements of an athletic swing.
Referring to
The shaft 1 of this embodiment is the central structural member of the swing training device consisting of a hollow elongated member by which the swing training device is swung. I presently contemplate that the shaft of this embodiment be made of uniform diameter of approximately the diameter of the grip portion of a typical baseball bat, softball bat, golf club, tennis racket or similar athletic equipment, and be made of a rigid and durable plastic or carbon fiber material. The shaft can be made of: various lengths, and alternate materials, such as high carbon steel, titanium, polycarbonate, etc. in order to better emulate the physical characteristics of the athletic equipment being trained. The grip 2 is the portion of the shaft 1 grasped by the user while executing a swing, which may be covered in a suitable gripping material such as leather, rubber, foam, or a synthetic material, etc. I presently contemplate the knob 3 to be attached to the shaft 1 by a threaded union, welding, epoxy, glue or other suitable method. The knob 3 of this embodiment approximates the knob of a typical baseball or softball bat. However, the knob 3 can be made of alternative geometries in order to better emulate the physical characteristics of the athletic equipment being trained. The knob 3 provides a reset passage 3a through which the retaining member 8 moves during the execution of the swing. This passage, and the retaining member 8 may be made of varying geometries or materials in order to provide resistance to accommodate swing being trained, or strength or abilities of the user.
The movable stop 4 is movably attached to the external surface of the shaft 1, and is of sufficient diameter to retain the sliding member 5 allowing the user to move it along the shaft in order to vary the starting position the sliding member 5. This allows for the swing training device to be configured for the training of multiple swing elements. I presently contemplate that the movable stop 4 to be made of a compliant material such that it is held in place against the shaft 1 by friction. However, the movable stop 4 can be made with a secondary element that actively applies a force against the shaft 1 to secure it in the desired starting position. The sliding member 5 is slidably attached to the shaft 1 and slides along the shaft between the movable stop 4 and the force capture member 6. I presently contemplate that the movable stop 4 and sliding member 5 be made of suitable materials, or contain suitable materials, such that the sliding member 5 is releasably retained against the movable stop 4 at the starting position.
At the end of the shaft 1 opposite the knob 3 is the force capture member 6 comprised of: the cap 6a, the force indicator 6b, and the friction device 6c. The cap 6a encloses the end of the shaft 1, and is of sufficient diameter to retain the sliding member 5. The force capture member 6 provides a means of measuring the force generated by the swing. This measurement may be calibrated to provide quantitative force measurements, however I presently suggest that relative or qualitative feedback provides sufficient data to improve athletic performance. The force capture member 6 is held against the shaft 1 by friction. I presently contemplate that the components 6a, 6b and 6c of the force capture member 6 of this be made of a single molded member of rigid durable plastic. However, these components may be independent members that are attached by threaded unions, welding, epoxy, glue or other suitable method, and may be independently made of varying materials such as rubber, polycarbonate, high carbon steel, titanium, etc., in order to provide the desired resistance for the swing being trained, strength or abilities of the user.
The force capture member 6 is attached to the retaining member 8 by means of the reset linkage 7. The reset linkage 7 is a rope, cable or rigid member connecting the force capture member 6 to the retaining member 8. The connection of the reset linkage 7 to the friction device 6 and retaining member 8 may be achieved by knotting, welding, epoxy, glue or other suitable method. The retaining member 8 is comprised of the reset grasp 8a and retaining stop 8b. The reset grasp 8a moves through the reset passage 3a of the knob 3 while the swing training device is used, and the retaining stop 8b constrains the movement of force capture member 6 to a desired distance. I currently contemplate that the reset grasp 8a and retaining stop 8b be made of a single rope element with the retaining stop 8b formed by a knot in said rope. However, the reset grasp 8a may be a rope, cable, or rigid member of suitable material and the retaining stop 8b may be made of any viable material securely attached to the rest grasp 8a and of sufficient diameter to not pass through the reset passage 3a within the knob 3. While I currently contemplate that the measurement of the force of the swing will be provided by the force indicator 6b, it is also true that the reset grasp 8a will move a distance proportional to the force indicator 6b. As such, the reset grasp 8a may alternatively provide a means of measuring the speed or force generated by the swing.
I presently contemplate that the knob 3, movable stop 4, sliding member 5 and the cap 6a of the force capture member 6, be made of a high contrasting color providing for enhanced visual assessment of swing mechanics. The intent of the high contrast color is to be a color with great contrast to the shaft 1 and knob 3, and thus easily identifiable by the user.
Operation of First Embodiment—
The swing training device describe above includes a movable stop 4 that allows for a variety of training methods. Referring to
In this method the swing training device is held at the grip 2 by a user 9 with both hands while the swing is performed with the movable stop 4 at the full downward position (closest to the user's hands). In the starting position (
Upon completing the swing, the user is able to quickly view the force of the swing by examining the displacement of the force capture member 6, or alternately of the displacement of the retaining member 8. The swing training device can then be quickly reset by pulling on the retaining member 8 in preparation for the execution of the next swing (

Description and Operation of Alternative Embodiments—
The first embodiment of this invention is intended to be the broadest embodiment, comprising a set of novel features of great utility that provide an improved swing training device. The following alternative embodiments are intended to highlight the specific novel features of this invention and represent embodiments that independently incorporate these features.
Referring to
The description of this second embodiment is similar to the first embodiment with the exception of consideration to accommodate the lack of the need for the reset linkage and retaining member of the first embodiment. The shaft 1 of this second embodiment is an elongated member with a hollow portion at one end minimally sized to accommodate the force capture member 6. I presently contemplate that the shaft of this embodiment be made of uniform diameter of approximately the diameter of the grip portion of a typical baseball bat, softball bat, golf club, tennis racket or similar athletic equipment, and be made of a rigid and durable plastic or carbon fiber material. The shaft can be made of: various lengths, and alternate materials, such as high carbon steel, titanium, polycarbonate, etc. in order to better emulate the physical characteristics of the athletic equipment being trained.
At the end of the shaft 1 opposite the knob 3 is the force capture member 6, comprised of: the cap 6a, the force indicator 6b, and the friction device 6c. The cap 6a encloses the end of the shaft 1, and is of sufficient diameter to retain the sliding member 5. The retaining flange 10 constrains the movement of force capture member 6 to a desired distance. I presently contemplate that the components 6a, 6b and 6c of the force capture member 6, of this embodiment be independent members that are slidably attached to the retaining flange 10 and are then attached by threaded unions, welding, epoxy, glue or other suitable method, and may be independently made of varying materials such as rubber, polycarbonate, high carbon steel, titanium, etc., in order to provide the desired resistance for the swing being trained, strength or abilities of the user. The retaining flange 10, now encompassing the force capture member 6 is then similarly attached by threaded unions, welding, epoxy, glue or other suitable method to the shaft 1. However, any suitable means of manufacture and assembly is acceptable.
The method of operating the second embodiment described above is the same as the method of operating the first embodiment with the exception that the method of resetting the force capture member 6 is achieved by the user applying a force (pushing) the displaced force capture member toward the opposite end of the shaft 1 until it is returned to the starting position. This embodiment is intended to provide a swing training device for use with athletic swings in which a retaining member protruding from the knob end of the device is not desired.
Referring to
The description of this second embodiment is similar to the second embodiment with the exception of consideration to accommodate the force capture member 6 rigidly attached to the shaft 1. The shaft 1 of this third embodiment is an elongated member that may be made of a hollow or solid cross section. I presently contemplate that the shaft of this embodiment be made of uniform diameter of approximately the diameter of the grip portion of a typical baseball bat, softball bat, golf club, tennis racket or similar athletic equipment, and be made of a rigid and durable plastic or carbon fiber material. The shaft can be made of; various lengths, and alternate materials, such as high carbon steel, titanium, polycarbonate, etc. in order to better emulate the physical characteristics of the athletic equipment being trained. At the end of the shaft 1 opposite the knob 3 is the force capture member 6 that encloses the end of the shaft 1, and is of sufficient diameter to retain the sliding member 5. I presently contemplate the force capture member 6 to be attached to the shaft 1 by a threaded union, welding, epoxy, glue or other suitable method.
The method of operating the third embodiment described above is the same as the method of operating the second embodiment with the exception that this embodiment provides only audible, tactile and visual feedback to the user pertaining the timing of the swing at the moment of full extension of the swing and simulates the striking of an object. This embodiment is intended to provide a simplified swing training device for use with younger athletes or in instanced where the feedback provided by the displacement of the force capture member is of limited training value, and to provide a lower cost swing training device.
From the description above, a number of advantages of some embodiments of my swing training device become evident:
(a) A user may think they are performing each swing identical to a preceding swing, however subtle and often unnoticed difference such as grip pressure, stride length, etc. can have great impacts on the force generated by the swing. The force capture member of at least one embodiment descried above provides for a multitude of force measurements, thus the force generated by a swing may be quickly compared the force generated by subsequent swings without the need to reconfigure the device from one swing to the next. As such, the training utility of my swing training device provides an advantage over prior at devices.
(b) Optimal results of an athletic swing are achieved when a user strikes an object, such as a ball, puck, etc., at the precise moment their swing is fully extended with a forceful snap of the wrists. The swing training device of at least one embodiment described above provides audible, tactile and visual feedback to the user pertaining the timing of the swing at the moment of full extension and simulates the striking of an object. This visual feedback can be aided by the use of contrasting colors incorporated into the design. Further, at least one embodiment above provides quantifiable feedback at precisely the moment of full extension of the user's swing. Thus, a novel training device and training methods are provided that allow the user to optimize the timing and force at this critical moment of the swing. As such the training utility of my swing training device provides an advantage over prior art devices.
(c) At least one embodiment described above, provides a means of quickly resetting the swing training device that minimally alters the training position, thus training time is maximized by allowing the user to perform a maximum number of swings in a given period of time.
(d) The movable stop of at least one embodiment described above provides for a plurality of training methods to be performed by the swing training device. This novel feature of my swing training device provides utility over the prior art devices by allowing for training methods specifically designed to focus training on various elements of a swing.
(e) Further, the movable stop described above provides a means of retaining the sliding member in the starting position. This design element allows the swing training device to be used to train a multitude of athletic swings, particularly those performed on a vertical plane such as golf swings.
(f) Lastly the swing training device described above is easily scalable to accommodate a broad range of athletic equipment and user abilities. Thus, an effective and low cost training device can be provided for the training of athletic swings at all levels of athletics and related leisure activities.
Accordingly, the reader will see that the swing training device of the various embodiments provides a swing training device and training methods that aid a user in developing optimal athletic results by training multiple elements of a swing, and in at least one embodiment quantifying the results of said swing. The swing training device can be used to quantify the force produced by the swing of a user for a multitude of swings without the need to be configured from one swing to the next, and provides audible, tactile and visual feedback to the user pertaining the timing of the swing at the moment of full extension and simulates the striking of an object. This visual feedback can be aided by the use of contrasting colors incorporated into the design. Further, at least one embodiment above provides quantifiable feedback at the critical moment of full extension of the user's swing. The movable stop provides for a plurality of training methods to be performed with the swing training device, and allows for training methods specifically designed to focus training on various elements of a swing. Additionally, the movable stop described above provides a means of retaining the sliding member in the starting position allowing the swing training device to be used to train a multitude of athletic swings, particularly those performed on a vertical plane such as golf swings.
Although the description above contains many specificities, these should not be construed as limiting the scope of the embodiments but as merely providing illustrations of some of several embodiments. For example, the use of a grip and a knob on the swing training device is not critical to the function or training utility of the device but rather serves to aid the comfort and physical interpretation of the device for the user. One skilled in the art will recognize that the swing training device can be made of varying form factors intended to represent alternative athletic equipment, such as a golf club, cricket bat, tennis racket, etc. without departing from the objects of the invention. Additionally, the training methods of the embodiments are representative and illustrate the versatility of the movable stop, and are not intended to be inclusive of all training methods provided by the swing training device. For example, training methods employing the use of only one hand of the user further provide for focused training on one or more elements of a swing. Further, depending on the specific implementation of the design of the swing training device, the swing training device may be used to strike objects such as a baseball, golf ball, tennis ball, etc. or representative training balls thereof; or be made of varying materials to provide for a training device of a weight significantly greater or less than the weigh the athletic equipment used in the sport being trained.
Thus the scope of the embodiments should be determined by the appended claims and their legal equivalents, rather than by the examples given.
