The present invention generally relates to sporting good equipment for use as a grip teaching aid or training device. More particularly, the present invention relates to a teaching aid or training device for facilitating and developing the proper grip of a handle of sporting equipment or other devices having a handle, such as a baseball bat handle, for use by either right-handed or left-handed individuals. The present invention could be used as a grip for a handle of sporting equipment, or any other device having a handle.
Many different sports and activities require the use of equipment that is swung to strike an object, such as a baseball bat for baseball, a softball bat for softball or a golf club in golf. The individual's grip on the particular equipment, such as the baseball bat, is typically important for proper swinging motion and striking ability on the object. It is well known in the art of sporting goods to provide gripping aids for encouraging a proper grip of the handle of the equipment, such as the handle of a baseball bat, softball bat or golf club.
One of the most common and leading causes of inconsistencies in athletic swings in baseball, softball and golf are the grip and grip alignment. In many instances, the positioning of the hand and the pressure applied to the grip will determine the swing path toward the ball. Many individuals are unable to consistently grip the handle properly, which can lead to undesired results in the swing, such as uneven or inconsistent swing paths, or a weaker swing than had the individual used a proper grip.
In baseball or softball, for example, a proper grip on the bat is important to maximize strength and swinging motion for striking the baseball. A proper grip in baseball or softball is such that the bat is held primarily in the fingers of the hand so that the second row of knuckles (i.e., middle row of knuckles) of the individual are lined up with each other. A baseball or softball bat should not be held in the palm of the hands. Holding a baseball or softball bat in the palm of the hands inhibits the flexion of the wrists during the swing, and decreases the individual's natural power and quickness during the swinging motion. In addition, holding the bat in the palm encourages an improper swinging motion which can facilitate injury to the individual while swinging and can decrease the bat stability while swinging thereby decreasing power.
Various devices are known in the sporting goods art for promoting a proper grip. Many of these devices, for example, wrap around the handle and include a raised surface portion for aligning the hands. One known device in the art provides a bat grip that includes upper and lower separated segments that wrap completely around the bat handle and allow for the use of both hands by a left-handed or right-handed player and has a raised surface portion for knuckle alignment. This type of device, however, maintains a generally artificial feel with respect to the bat handle and prevents the individual from obtaining the natural feel of the bat. It can also be difficult to easily put on the bat or remove from the bat.
Other devices known in the art comprise baseball grips of a material which enhances the user's hold on the bat, e.g., rubber or neoprene materials. Grips have been formed such that they conform to the hands of the user while other grips have indentions for receiving the user's fingers in such a way that the bat is more easily gripped. These types of grips, however, do not typically allow for the user to maintain a natural feel of the bat handle. These known grips can also be cumbersome and difficult to apply to or remove from a bat handle.
A number of grips exist for instructing a user on how to properly grip a baseball bat, golf club, tennis racket, or other similar such sporting equipment. Grips specifically configured for instructing an individual on how to properly grasp the equipment are generally known in the art. For example, U.S. Pat. No. 7,125,353 (Blount) discloses a baseball bat grip that encourages a user to maintain a proper grip throughout the entire swing of the baseball bat. The grip includes a pair of protrusions that are secured between a V-shaped opening between the user's index finger and thumb on each hand. The grip further includes certain ridges and valleys configured to receive the user's fingers to further maintain an appropriate grip.
Such grips suffer from a number of disadvantages. In particular, these grips do not properly instruct a user on how to position the baseball bat such that when the user swings the baseball bat, the so-called trademark portion of the bat is positioned correctly with respect to the user's hands and with respect to the batted ball. Further, the grip of the '353 patent suffers other disadvantages, namely, the V-shaped openings formed by the protrusions result in a grip that rests too deeply into the user's hand, thus requiring that the user to control the bat with the palm of the user's hand instead of the fingers of the user's hand. Further, the ridges and valleys do not conform to the user's hand or instruct the user on where to position each of the user's respective fingers on the baseball bat. In addition, the '353 patent is configured to instruct a user on how to achieve a “knocked knuckles” grip throughout the swing. Such a “knocked knuckles” grip, however, can be disadvantageous because the “knocked knuckles” grip significantly reduces a user's ability to securely grasp the baseball bat and swing the bat in a controlled, powerful manner.
Other devices known in the art which include grips for sporting equipment cannot be easily installed on the sporting equipment due to the shape of such equipment. Specifically, a baseball bat includes a knob at a first end, a barrel at a second end, and a handle portion between the knob and the barrel. The user grips the baseball bat at the handle portion, and as such training aids for teaching and promoting proper grip are installed on the handle portion. The knob and barrel, however, are typically much larger in diameter than the handle portion. Thus, installing a grip known in the art is difficult, as the grip must be stretched over the knob, yet must retain a tight fit to the handle portion. Such known grips that accomplish this tend to become loose over time due to stretching. They too can be cumbersome to put on and remove.
Accordingly, there is an unsatisfied need in the art for a training device for encouraging a proper grip of a handle, such as a baseball bat handle, that can be interchangeable for a right-handed or left-handed individual, that is easily applied to and removed from a handle, and promotes as much direct contact between the individual's hands and the handle to allow close to a “natural feel” as possible during use.
The ability to provide a specific sensation and placement of the grip into the player's fingers during the set-up and the swing helps the player to develop and maintain the proper and most efficient grip for that given sport. The present invention provides the individual with the proper sensation and positioning for the index finger of the hand during the grip, while also forcing the rest of the player's fingers into the proper grip alignment directly on the handle. The index finger is also known as, and will be referred to as, the “trigger finger.”
The present invention addresses the various disadvantages of known prior art training devices for promoting proper grip of a handle. The training device of the present invention generally includes a unitary member having a defined area for placement of the trigger finger, while simultaneously forcing the other fingers into proper alignment and which can be easily employed during use and can be adapted for use in any activity requiring a bat, racquet, club, etc., such as baseball, softball, golf, tennis, lacrosse, cricket, etc. It could also be used for non-sport related activities, such as using a scythe, a sledgehammer, a shovel, etc. The training device of the present invention can comprise a single unitary elongated tube-like body for fitting around the handle of a sporting equipment, such as a baseball bat, and can be comprised of any material known in the art such as vinyl, rubber, plastic, neoprene and the like.
In an embodiment of the present invention, the device includes a protruding saddle (i.e., trigger finger receiving area) defined by a finger groove portion. The player's “trigger finger” securely and comfortably fits into the trigger finger receiving area.
An embodiment of the present includes a device having a visual alignment guide on the rear portion. A visual alignment guide provides the individual with the proper sensation of control and position with the “trigger finger” during use.
It is an object of the present invention to provide an improved device for promoting proper grip and alignment (a gripping aid) of the hands on a baseball bat or other sporting equipment.
It is another object of the present invention to provide an improved gripping aid that can be easily placed onto or removed from a baseball bat or other sporting equipment.
It is yet another object of the present invention to provide an improved gripping aid that can be easily interchangeable for use by a right-handed individual or a left-handed individual.
It is still yet another object of the present invention to provide an improved gripping aid that allows for a substantial amount of direct contact between a baseball bat or other sporting equipment and the individual's hands.
It is another object of the present invention to provide an improved gripping aid that is small and easily attached to and detached from different sized ball striking equipment and ball striking equipment varying in cross-sectional diameters of the handle.
Other objects of the present invention will become apparent from the description to follow and from the appended claims.
The present invention is now described in its preferred forms. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be evident, however, to one skilled in the art that the present invention may be practiced without these specific details.
The training or teaching device/training or teaching grip of the present invention is shown in the figures and referred to generally at numeral 10. The training grip in accordance with the present invention is generally a device designed and configured to securely attach to the handle of an object-striking piece of sporting equipment, such as a ball-striking piece of sporting equipment, such as a baseball bat. The training grip in accordance with the present invention generally provides a finger groove area for the individual to place his or her finger when gripping the handle of the object-striking piece of sporting equipment.

Horizontal edges 122a, 122b form two opposing curved boot areas 130a, 130b, each of which in turn curves and extends upwardly towards edge 118 for defining the curved lip or edge 118. The upwardly extending edge in turn defines a curved space or indentation 131a, 131b for receiving and accommodating the individual's thumb during use of training grip 110 while playing golf. It should be appreciated that thumb accommodating space 131a, 131b receives and accommodates the individual's thumb 106 on the lower hand (i.e., strong hand) depending on whether the individual is employing a right-handed or left-handed swing.
In the same manner as described above, the placement of the individual's trigger finger 102 in trigger finger receiving area 114 and the individual's thumb 106 at the thumb accommodating space 131a, 131b causes the individual's remaining fingers 105 to be correctly aligned, thus causing a correct grip on the golf club during use.
