1. Field of the Invention
The claimed invention relates to devices used to enhance the performance of a baseball player's batting swing, and more specifically to adjustable weighted attachments for baseball bats.
2. Description of the Prior Art
Athletes train to become better players in their sport, spending hours in practicing different aspects of the sport. As an example, baseball players continually practice hitting, fielding, and base running to become a better baseball player. In the past, different types of training devices have been used that were intended to enhance the performance of an athlete, particularly in sports requiring hand held equipment such as baseball, tennis, and hockey. These devices were often developed and used based on impressions that the devices would enhance an athlete's performance without actually studying the effect that a particular device might have upon a player's performance.
One of the more popular types of training methods has been attaching weights to an athlete's hand held playing equipment such as baseball bats, tennis racquets, hockey sticks, or golf clubs. The attaching of extra weight to these types of equipment is thought to strengthen the athlete's muscles through practice while using such weighted equipment. However, placement of such weight upon the equipment has seldom been studied. In some applications, placement of extra weight upon playing equipment such as a baseball bat can actually be counter productive to the performance of the athlete due to the improper placement of the weight. If the weighted device is not secured about a baseball bat in the proper location, the extra weight can interrupt the baseball player's proper swinging form, possibly resulting in poor hitting performance. Several of the prior art weighted training devices and their disadvantages are discussed below.
U.S. Pat. No. 5,484,156, issued to Giguere discloses a Golf Club Practice Swing Weight that comprises a flexible web arranged to have secured thereto a plurality of flexible pouches. The strap member can have a hook and loop fastener surface using a ring member. The device can be mounted about a shaft, such as a golf shaft whereupon it can be secured about itself. This training device provides only a pair of weights that conforms to the curvature of the golf club shaft, but does not provide an expedient way to add or remove a discrete amount of weight having a solid, reshapeable curved surface for engagement with a rounded surface such as a handle of a baseball bat. This makes it difficult for the user or athletic trainer to accurately monitor the amount of weight being used in the training device. Further, this training device does not have a memory characteristic allowing users to reattach the training device to the golf club in the same location as previously positioned if removed. Further, this prior art does not teach the concept of employing a tacky rubber-like or rubber surface on an inner surface of a baseball bat weight training belt to resist slippage when engaged to a round baseball bat handle according to features of my invention.
Athletes often use the training device during practice sessions and then remove the training device during actual play. In prior art training devices of this type, it would be difficult if not impossible to place the training device on the golf shaft at the same location as previously placed due to the lack of formability memory training devices of this type have. This point is important in that an athlete can use and remove the training device from the golf club while being able to consistently place the training device on the club in the same location thereby providing a uniform training experience.
U.S. Pat. No. 4,538,812, issued to Mugford et al. discloses a Weight Device for Athletic Racket having two sheets separated by an elastic member. Each sheet contains a plurality of egg-shaped weights (in section) that are housed in chambers that are formed by the joining of two layers of flexible material at spaced locations. Attachment can be made using VELCRO type surfaces. This training device presents many of the same problems as previously discussed. In the embodiment shown in
U.S. Pat. No. 4,364,560, issued to Gemmel includes a practice weight for a flat sided hockey stick that is a U-shaped weight that can be clamped onto a shaft or handle and is then clamped by clamp screws and then secured by a flexible cover that is wrapped around the shaft and itself. The clamp feature of this training device provides a device that can be removably coupled to a hockey stick while providing means for preventing the training device from shifting during use. However, this training device does not allow for easy repeatable placement of the training device upon the hockey stick. Therefore, there is a need for a training device that provides a quick and easy way to reattach a weighted training device to a hand held athletic tool in the same location as previously placed. This type of a picture weight device has not been constructed for use with a round tapered handle of a baseball bat which required different physical characteristics.
Finally, U.S. Pat. No. 4,000,893, issued to Evans teaches a weight holder and method of use that can removably add weight at selected positions on a flat sided racket and possibly a bat. The device is made of flexible material that wraps around a shaft or handle and overlaps at the ends for removable, adjustable securement and positioning. The holder comprises two, spaced pockets with a weight in each pocket and these weights can be removed to change weight size and weight. The weights disclosed in this training device are cylindrical and non-formable. Weights of this type tend to shift during use of the tennis racquet do the surface profile of the weight not being similar to the surface profile of the racquet. Therefore, there is a need for a weighted training device that provides a weight that conforms to the curvature of a hand held athletic tool that prevents the weights from shifting during use of the training device.
As athletic training methods have advanced, athletic trainers have studied the effects of different types of training devices upon the performance of an athlete. Improved technology such as slow motion imaging has helped athletes and athletic trainers to study the behavior of athletes as they perform different tasks within a sport. These advances have made athletes and athletic trainers aware that some of the training methods previously used actually hinder an athlete's performance instead of improving performance. As an example, some baseball trainers who study hitting discourage the use of the doughnut type weight that has been in use for many years due to the negative effects weighting of this kind is thought to have on a hitter's form. Therefore there is a long felt need for a weighted training device that can provide a solution to the problems previously explained in the prior art.
Accordingly, there is a need for a weighted device that can be placed about the baseball bat in a more appropriate position than that of the ordinary doughnut type weight. To satisfy this need as well as others, an objective of the claimed invention is to provide an adjustable weight training belt for use with a baseball bat.
Another object of the claimed invention is to provide an adjustable weight training belt where the amount of weight may be varied by changing the amount of weight contained with an adjustable weight training belt.
Yet another object of the claimed invention is to provide an adjustable weight training belt where the weights have formable memory allowing the adjustable weight training belt to be repeatedly placed in the same location upon the hand held athletic tool as previously placed.
A further object of the claimed invention is to provide an adjustable weight training belt where the weights are formable to prevent the weights from shifting during use.
A yet further object of the claimed invention is to provide an adjustable weight training belt where the weights are formable to prevent the training belt from moving about the surface of the hand held athletic tool.
To achieve the foregoing objectives, the claimed invention provides an adjustable weight training belt for use with a baseball bat. The belt comprises a first layer of flexible material having a front face and a back face. A hook and loop fastening system with the hook portion of the fastening system on the front face and the loop portion of the fastening system on the back face is employed to increase or decrease the area encircled by the belt.
A second layer of flexible material having a front face and a back face is connected to the first layer forming a plurality of pockets between the front face of the first layer and the back face of the second layer. The front face of the second layer has a high coefficient of friction to resist movement of the belt when placed about the barrel of a baseball bat.
A plurality of malleable weights are engaged in the pockets. The weights formable to the curved surface of the barrel of the baseball bat creating a substantially similar surface profile contributing to the resistance of movement of the training belt against the surface of the bat. The weights have a memory characteristic enabling a user to place the weights in substantially the same location along the surface of a baseball bat from one use to another by matching the surface profile of the weights to the curvature of the baseball bat. In one embodiment of the invention the malleable weights are removably engaged in the pockets. In another embodiment of the invention the pockets are sewn closed permanently retaining the malleable weights.
In another embodiment of the invention shown in
The VELCRO fastener 50 allows use of the training belt 10 on full sized wooden and metal bats as well as smaller bats sized for youth baseball. The belt 10 is sized and shaped to enable it to be placed preferably from about ½ inch to about 8 inches from the grip of the person holding the baseball bat 60 as shown in
When assembled, the first and second layers are positioned in superimposed relation to provide the belt with the pocketed weighted end 61, and an elongated unpocketed end 62 is attached in end-to-end relation to said pocketed weighted end 61. The hooks being on one side of the belt and with the loops being on an opposite side enable said unpocketed end 62 to be attached to said pocketed weighted end 61 on an outside surface area of said pocketed weighted end 61 when position in lapped relation to one another when attached to a bat handle.
The unpocketed end of the belt has a length almost as long as the weighted unpocketed end of the belt to provide a relatively large area of engaged hooks and loops to ensure that the weights will be secured in tight engagement with the bat handle. The large area in my preferred embodiment can be approximately 4 3/4 inch by approximately 2 inches to provide a very solid connection.
Due to the various types of grips employed from one baseball player to another as well as from one situation to another, the adjustable weight training belt 10 may need to be placed close to the knob 160 of the bat 60 or close to the hitting area 170 of the bat 60. The placement of the training belt 10 above the hands 180 of the athlete positions the training belt 10 in a more balanced location than that of the prior art devices previously discussed in the background of the invention section. Since the training belt 10 is place in a more properly balanced location upon the baseball bat 60, the added weight of the training belt 10 does not interfere with the swinging form of the athlete. The ability to form the training belt 10 to the curvature 190 of the tapered handle of a baseball bat 60 and along any part of the bat 60 gives the claimed invention an important advantage over the prior art. The prior art did not provide means for conforming a training device to a hand held athletic tool while also providing means for allowing a user to remove the training device and reliably place the training device back on the hand held athletic tool in the same location as previously placed.
The training belt 10 is generally used by first shaping the malleable weights 30 so that the surface profile 80 of the weights 30 are substantially similar to the curvature 190 of the baseball bat 60 as shown in
After the weights 30 have been properly formed, the weighted portion of the training belt 10 is placed against the handle 200 of the bat 60 from about ½ inch to about 8 inches above the hands 180 of the athlete using the bat 60 as shown in
It is contemplated that my adjustable weight training belt can be of several different sizes. As stated in one embodiment, I have four lead weights, each having approximately a 1 inch width and each are approximately 1/8 inch thick. The total weight of the four weights is 4 ounces.
I also contemplate a so-called 8 ounce bat belt where the pockets will be enlarged and the bent will be wider to accommodate larger weights, each of 2 ounces having a 1/8 inch thickness, a 1 inch width and each being approximately 2 or 3 inches in length.
My training belt 10 can be approximately 11 inches in width with the so-called pocket end of the belt being 6 inches and with an unpocketed opposite end being approximately 5 inches in length. The unpocketed end is lap engaged on the pocketed end and is sewn with two lines of stitching to connect the pocketed end with the unpocketed end. Tacky rubberized fabric or rubber is provided on the pocketed end and the unpocketred end has a hook side which is positioned on the same side of the belt as the tacky rubberized surface. The pocketed end has a loop side opposite to its tacky rubberized side so that when the belt is wrapped about the handle of a bat, the hook and lap faces or sides will be confronting for lapping engagement as shown in the drawings. The hook and lap face can be attached and reattached as the user adjusts the position of the handle and as the user squeezes the weights to conform the weights to the tapered shape of the bat handle, thus assuring that the tacky rubberized surface can gain a firm grip on the exterior surface of the bat handle. Once adjusted to a desired position, the training belt can then be used with the bat to enable a user to engage in a training exercise to improve the user's batting stroke.
