This invention relates generally to sports safety equipment, and more particularly to hand-protection equipment for batting sports.
Many sports require the use of a bat or a stick, including for example baseball, softball, ice hockey, field hockey, and cricket. Today, many sports players use safety equipment to protect their hands during play with bats and sticks. For example, ice hockey players typically use gloves while playing, and baseball batters commonly wear gloves to protect their hands while holding a bat.
In baseball, when a player swings a bat, and the bat hits a pitched ball, sometimes vibration is transmitted from the bat to the player's hands that can be quite severe. This vibration can cause what is commonly called “bat sting”.
In professional baseball, the average speed of a pitched baseball is approximately 90 MPH, and typical pitched ball speeds range from 80 MPH to 100 MPH, with some pitchers consistently pitching over 100 MPH. The resulting instantaneous peak impact of the ball striking the swinging bat can reach 5,000 to 10,000 pounds of force.
When a bat hits a ball, vibrations are transmitted from the impact site down the shaft of the bat to the player's hands. These vibrations are caused by bending modes of the bat. Using high speed photography, vibration modes of a bat have been measured and studied.
Ideally, the player attempts to hit the ball within a “sweet spot” of the bat. The “sweet spot” is the location on the bat where bat vibrations are minimized, and therefore is where on the bat to hit the ball so that “bat sting” is minimized. If the ball hits the bat outside the area of the “sweet spot”, the bending modes of the bat can be severe, and strong vibrations are transmitted to the player's hands. Bat sting can cause pain in the player's hands and can also result in bruising and injury to the player's hands. The hand most affected by bat vibrations is the “distal” hand, the distal hand being the hand that is closest to the point of contact between the ball and the bat. For a right handed batter, the distal hand would be the batter's right hand.
Bat sting can be so painful as to interfere with both the player's concentration and confidence, and therefore can interfere with the player's batting performance. Therefore, players attempt to hit the ball within the sweet spot of the bat as often as possible.
Because bat sting can cause injury to the player's hands, and is detrimental to batting performance, various ways to reduce vibrational shock to a batter's hands have been proposed.
One example is a cushioning pad made to be held between the batter's hand and the bat, as taught in Lomedico, U.S. Pat. No. 9,603,394 B2. In particular, Lomedico teaches a batting pad made from a cushioning material to be placed in the batter's palm area, also having a ring portion adapted to fit over a batter's thumb. However, the pad and ring portions can unintentionally pivot around the thumb of the batter, and therefore the cushioning pad of Lomedico can be oriented at any angle with respect to the thumb, reducing the effectiveness of the device. The need to carefully and repeatedly verify and adjust the cushioning pad of Lomedico so that it is correctly placed within the palm area of the hand can be distracting to the batter as the batter prepares to hit an incoming ball.
The batting aid of the invention provides a protective resiliently deformable flap that cushions a portion of the palm of the distal hand of a batter. The protective resiliently deformable flap minimizes the transmission of vibration and impact from the bat so as to reduce pain and injury from bat sting.
The batting aid of the invention also conforms to the handle of the bat to improve the player's grip on the bat. In some embodiments, the protective resiliently deformable flap can provide enhanced friction between the batting aid and the shaft of the bat. In addition, the protective resiliently deformable flap aides in positioning the metacarpals (bones located within the hand) away from the shaft of the bat, which can provide improved control of the bat by giving the proximal phalanges of the player's fingers a “lighter touch”. This enhanced “lighter touch” can provide more precise finger control of the bat angle, can provide greater wrist flexibility, and can provide enhanced bat swinging mechanics.
The batting aid of the invention is conveniently secured to the thumb of the player's distal hand by way of a thumb ring that forms a thumbhole through which the thumb is inserted. The thumb ring is coupled to a saddle of the batting aid, which includes a crest portion and at least one resiliently deformable flap that extends from the crest portion to overlay at least a portion of the thenar space on the palmar side of the batter's distal hand, and to self-align the crest portion in an optimal position to straddle the first web space of the hand. Because the saddle of the batting aid is self-aligning, the batter does not have to take time to reposition the batting aid, and therefore the batter can more easily concentrate on hitting pitched balls.
A general aspect of the invention is a batting aid to be worn on a thumb of a distal hand of a baseball player while gripping a handle of a bat with both a proximal hand and the distal hand, the batting aid minimizing transmission of vibration and impact from the bat so as to reduce pain and injury, the batting aid also improving a player's grip on the bat. The batting aid includes: a thumb ring defining a thumbhole for receiving the thumb of the distal hand, the thumb ring being configured to substantially surround a proximal phalanx of the thumb of the distal hand to secure the thumb ring to the proximal phalanx of the thumb of the player's distal hand; and a saddle integrated with and projecting from the thumb ring,
The saddle includes a crest portion configured to align with and substantially straddle the first web space of the distal had and extend from the ring to a conforming portion of an external distal boundary of the saddle. A concave portion of an internal surface as defined by the conforming portion of the external distal boundary is configured to engage a distal portion of the second metacarpal bone of the distal hand; and at least one resiliently deformable flap, the resiliently deformable flap configured to extend from the crest portion along the palmar side of the distal hand to overlay at least a portion of the thenar space of the distal hand, the distal end of the saddle being configured to extend substantially along a middle portion of the second metacarpal bone of the distal hand.
In some embodiments, the resiliently deformable flap has an outer surface that includes a concave surface configured so as to substantially conform to a portion of the handle of the bat when the player grips the handle of the bat.
In some embodiments, the concave surface is an elliptical concave surface.
In some embodiments, the thumb ring and the saddle are made from a resiliently deformable material selected from a group including: injectable rubber, Sorbothane®, silicone rubber, and silicone.
In some embodiments, the saddle is configured so as to act as a cushion that absorbs vibration and impacts from the handle of the bat.
In some embodiments, the resiliently deformable flap is made of a material that provides enhanced friction where the resiliently deformable flap and handle of the bat make contact while the handle of the bat is held.
In some embodiments, the resiliently deformable flap includes an enhanced-friction surface that provides enhanced friction where the resiliently deformable flap and handle of the bat make contact while the handle of the bat is held.
In some embodiments, the saddle further includes: a second resiliently deformable flap extending in bilaterally symmetric relationship with the first resiliently deformable flap.
In some embodiments, the saddle further includes: a second resiliently deformable flap extending less than the first resiliently deformable flap.
In some embodiments, an inner surface of the saddle together with an inner surface of the thumb ring are configured to engage and substantially span a generally V-shaped region formed between the thumb and a confronting side of the second metacarpal of the distal hand.
In some embodiments, the crest portion of the saddle substantially spans a region between the distal end of the proximal phalanx of the thumb and the distal end of the second metacarpal bone of the distal hand.
In some embodiments, the resiliently deformable flap of the saddle is configured such that when the distal hand grips the bat, the bat is biased in the distal hand so as to be angled forward towards the fingers of the distal hand.
Many additional features and advantages will become apparent to those skilled in the art upon reading the following description, when considered in conjunction with the accompanying figures, wherein:
With reference to
As is illustrated by
With reference to
The portion 113c of inner surface 113 as defined by the conforming portion 115′ is concave in shape and is thereby configured to engage with the second metacarpal bone 111 of the distal hand 108 at a location at or below the second metacarpophalangeal (MCP) joint (109,
With reference to
In some embodiments, the portion 117b of outer surface 117 that covers resiliently deformable flaps 116 is made of a material that provides enhanced friction, where one of the resiliently deformable flaps 116 and the bat handle 402 make contact while the bat handle 402 is gripped.
In some embodiments, the portions 117d of the outer surface 117 shared by the resiliently deformable flaps 116 have a concave surface 117b configured so as to substantially conform to the bat handle 402 when the distal hand 108 grips the bat handle 402. In some embodiments, the resiliently deformable flaps 116 each have a concave surface 117b that is elliptical in shape.
In some embodiments, the saddle 114 is configured so as to act as a cushion that absorbs vibration and impacts from the bat handle 402.
In some embodiments, the thumb ring 112 and the saddle 114 are made from a resiliently deformable material selected from a group including: injectable rubber, Sorbothane®, silicone rubber, and silicone.
With reference to
In some embodiments, the two resiliently deformable flaps 116 extend unequally.
In this embodiment, the portion 113a of inner surface 113 of the saddle 114 spans between the resiliently deformable flaps 116 and the underside of crest portion 118 by which the batting aid 100 rests upon the skin of the user's first web space (under the crest portion 118), engages with the second metacarpal 111 (at the conforming portion 115′ of the external distal boundary 115) and the thenar space 103 on the palmer and dorsal sides of the distal hand (under the palmer and dorsal deformable flaps 116). The portion 113a of inner surface 113 is also shared with the underside of a distal portion of the thumb ring 112 (See

With reference to
With reference to
Because the two resiliently deformable flaps 116 are self-aligning with the distal hand 108, the batter does not have to spend time aligning the batting aid 100, and the batter can therefore concentrate on hitting pitched balls.
With reference to
In this embodiment, the crest portion 118 of the saddle 114 substantially spans a length 107 over the first web space, a region that lies between the distal end of the proximal phalanx of the thumb 104 and the distal end of the second metacarpal bone 111 of the distal hand 108. The concave conforming portion 115′ of the external distal boundary 115 of the saddle 114 defines a concave portion 113c (

One resiliently deformable flap 116 of the saddle 114 is captured between the bat handle 402 and the palm 110 (shown in
With reference to
Also shown are the thumb ring 112 and the saddle 114. One of the two resiliently deformable flaps 116 of the saddle 114 is pressed between the bat handle 402 and the palm 110 of the player's distal hand 108.
The resiliently deformable flap 116 captured between the bat handle 402 and the palm 110 of the player's distal hand 108 cushions the vibrations and impact from the bat handle 402 as the bat hits a pitched ball, protecting the player from pain and injury.
With reference to
Also shown are the thumb ring 112 and the saddle 114, the saddle 114 including the crest portion 118 and a second one of two resiliently deformable flaps 116, the second resiliently deformable flap 116 shown extending away from the bat handle 402. The other flap of the two resiliently deformable flaps 116 (hidden in this view) is captured between the bat handle 402 and the palm 110 of the player's distal hand 108.
In this embodiment, both the resiliently deformable flaps 116 are self-aligning with the distal hand 108, and therefore the batter does not have to spend time aligning the batting aid 100, and the batter can therefore concentrate on hitting pitched balls.
In this embodiment, the resiliently deformable flap 116 (hidden in this view) pressed into contact with the bat handle 402 is configured such that when the distal hand 108 grips the bat handle 402, the bat handle 402 is biased in the distal hand 108 so as to be angled forward towards the fingers 404 of the distal hand 108.
