The invention relates to athletic equipment, and more particularly, to swinging implements (i.e., baseball bats, tennis rackets, golf clubs, etc.) and ergonomically-designed handles that improve grip, decrease injuries and improve performance for users of such equipment.
Baseball bats are very well known and well represented in patents. According to Major League Baseball (“MLB”) rules, the baseball bat is limited by Rule 1.10 (a) The bat shall be a smooth, round stick not more than 2¾ inches in diameter at the thickest part and not more than 42 inches in length. Nevertheless, many changes have been made to the knob and handle end of baseball bats over time.
Two of these changes include the ProXR bat handle, as disclosed in U.S. Pat. No. 7,744,497, and the Axe bat handle, as disclosed in U.S. Pat. No. 7,878,930.
These changes have been allowed in the MLB under Rule 1.10 (c) The bat handle, for not more than 18 inches from its end, may be covered or treated with any material or substance to improve the grip.
Classic baseball bat handle and knob had the appearance of the rounded shaft, being capped with a traditional knob without any transition (see
Over the years, slight flaring has been added based upon batters' comfort needs (see
In specific regard to the ProXR handle described in their patents, such handles are essentially a standard handle angled to fit more ergonomically in the hand (see FIG. 23 of U.S. Pat. No. 7,744,497).
In regard to the ‘axe handle,’ the handle is very specifically akin the handle of an axe, with flattened sides and a rounded butt end (see FIG. 1 of U.S. Pat. No. 7,878,930).
The foregoing changes have been added to improve grip, make the handle more ergonomic and help in swing path.
However, a particular problem with the knob/handle of baseball bats relates to injury of the user's hamate bone and soft tissue and muscles of the user's hypothenar eminence (the abductor digiti minimi, flexor digiti minimi brevis and the opponens digii minimi). This occurs due to the impact of the knob and handle on these anatomical areas/structures.
There is therefore a need for a handle for baseball bats, and other swinging athletic equipment, that provides improved grip and performance while decreasing the risk/incidence of injury to the user.
Disclosed herein are handles for sports equipment, such as baseball bats and the like. In various embodiments, the handle includes a first portion having a flared shape and no knob, a second portion having at least a partial knob, and an axis extending along a vertical axis of the handle and separating the first and second portions.
In various embodiments, the first portion of the handle is configured to interface with the hypothenar side of a user's hand. In various embodiments, the first portion has a flared shape and no knob, and is configured to interface with the hypothenar side of the user's hand in a way that decreases pinpoint loading or overloading of one anatomic structure. In various embodiments, the anatomic structure is either the user's hypothenar area or the user's hamate bone. In various embodiments, the first portion includes a groove configured to unload the user's hypothenar area and the user's hamate bone.
In various embodiments, the second portion of the handle has at least a partial knob, and is configured to interface with the little finger of a user's hand. In various embodiments, the at least partial knob of the second portion includes a protuberance that is configured to engage the user's little finger. In various embodiments, the protuberance is configured to facilitates better grip, a pivot point for proximal part to glide across hypothenar eminence of the user's hand and better performance of the athletic equipment with which the handle is used. In various embodiments, the at least partial knob of the second portion of the handle includes an added weight, whereby balance, feel, swing path, pivot and hypothenar glide of the athletic equipment is improved.
In various embodiments, the athletic equipment with which the handle is used includes baseball bats, tennis rackets and golf clubs.
The accompanying figures, which are incorporated in and constitute a part of the specification, illustrate preferred embodiments of the invention and, together with the description, serve to explain the objects, advantages, and principles of the invention. Embodiments of the invention are in no way limited by the following figures:
Disclosed herein are gripped handles for baseball bats and other athletic swinging equipment. Use of the term “distal” herein is understood to designate a direction away from a user of the bat (e.g., the non-handle end of the bat that is farther from the user's body), and use of the term “proximal” herein is understood to designate a direction towards to the user (e.g., the handle end of the bat that is held by the user, closer to the user's body).
The novel and inventive features of the handles of the invention include those numbered and discussed below:
As further discussed below, the gripped handles of the present invention have a knob-less flared side. This side has no protuberance to impact on the hypothenar eminence, nor specific structures within it. Being a broad, smooth surface, it can distribute any forces over a larger surface thereby decreasing potential injury.
This smooth, flared, knob-less side also allows for a unique motion in the hand that is known as ‘hypothenar glide.’ During the swinging of the bat or any handled instrument, instead of digging in and impacting into the hypothenar area of the batter/user's hand, the broad, smooth, knob-less flared side, allows the handle to glide across the hypothenar eminence of the hand. This decreases injury as well as improves bath swing path, release and whip of the bat. These all also improve batting performance.
The gripped handles of the present invention also have a unique ‘finger side.’ Whereas the grip of a standard knob includes a knob protuberance just below the hypothenar eminence of the user's hand (see
3. Hybrid Knob/Handle with Two Unique Halves
The gripped handles of the present invention include a flared, knob-less surface on the hypothenar side. This flare can be formed flat to any angle that the batter/user feels comfortable with and allows for force distribution over a larger area of the hypothenar area, and encourages the ‘hypothenar gliding action.’
On the finger side, the raised knob protuberance allows for direct little finger engagement to improve grip and act as pivot point of hypothenar gliding. This side can take many forms, including, but not limited to:
Unlike the angled ProXR and Axe handles, the bottom of the handles of the present invention are flat (i.e., not angled). This structure extends the finger side to the length of the hypothenar side, and adds some weight to the knob. This added weight provides benefits that include: providing a more balance bat feel due to more weight below the hands, allowing batters to swing a heavier bat, facilitating hypothenar gliding action of the handle due to weight distribution below the pivot point. Further, with better weight distribution and balance, batters can swing an ‘uncupped’ distal end of the bat which allows for more mass at the contact end of the bat.
In various embodiments, the handles of the present invention are formed from the same materials as the piece of athletic equipment with which they are being used, when either formed monolithically with the athletic equipment or as a separate component to be secured to the athletic equipment. Non-limiting examples of materials for handles to be used with a baseball bat include wood, aluminum, other metals and composites thereof.
Specific embodiments of the handles of the present invention will now be discussed in connection with the figures depicting the features of same.

A continuously flared, knob-less, bell-shaped handle 910 according to another embodiment is shown in
Extending the protuberance 1120 provides the following advantages:
The handle 1510 includes a transition zone 1530 formed between the hypothenar portion 1513 and the little finger portion 1519 discussed above.
The handle 1510 also includes a metacarpal ridge 1532 on a distal end of the transition zone 1530, where the flexion crease of the user's metacarpal joint engages the handle 1510. This allows for increased/improved grip, decreased slippage and increased power transfer.
The handle 1510 further includes a ramp/power slide 1534 on a proximal end of the transition zone 1530. During the bat swing, the user's hypothenar eminence area and hamate bone slide across the ramp/power slide 1534 of the transition zone 1530. This allows for increased whip action of the bat and decreases the load to the user's hypothenar area.
The handles of the present invention are not like the axe handle discussed above, or like the ProXR handle which is essentially an angled knob. The knob-handles disclosed herein is a unique hybrid knob of two distinct halves. In addition, it is a very important point that the knob portion of the handles of the present invention is perpendicular to the long axis thereof—it is not angled. This provides a traditional feel and is different than the axe handle and ProXR handle.
Objects and advantages of this invention are further illustrated by the following examples, but the particular materials and amounts thereof recited in these examples, as well as other conditions and details, should not be construed to unduly limit this invention.
A comparative study was conducted to decrease impact pressure on the hamate bone utilizing a hybrid baseball bat handle according to the present invention (i.e., an Axis/Phantom Bat Works Hybrid Handle) compared to the traditional bat handle knob.
Utilizing Fujifilm Prescale pressure film, we measured and recorded the impact pressure upon the hamate bone during ball impact while hitting. We compared a traditional knob turn model 243 handle (
We had the same batter take 8 swings with each handle and recorded it utilizing 3 different pressure film ranges, for a total of 48 total swings documented.
Fujifilm prescale reveals pressure distribution and magnitude between contact surfaces (see
The intensity of red color on the developing film correlates to the number of microcapsules broken and amount of increased pressure enacted on the hamate bone.
In each of these studies, the batter's hamate bone experienced significantly less peak and total load pressure with the inventive hybrid handle when compared to that with the traditional handle knob, as indicated by red color intensity on film.
These results illustrate that the unique design of the inventive hybrid handle significantly decreases impact peak and total load experienced by the batter's hamate bone during batting.
While the handles have been discussed in connection with baseball bats, the invention also includes handles for other sports equipment involving a user swinging, including, but not limited to, tennis rackets and golf clubs.
