(18) As used herein, comprising, including, containing, is, are, characterized by, and grammatical equivalents thereof are inclusive or open-ended terms that do not exclude additional unrecited elements or method steps. Comprising is to be interpreted as including the more restrictive terms consisting of and consisting essentially of.

(19) FIG. 1 is a top plan view of a palm of a right hand of a player. There is shown a palm of a hand 80 including an index finger 26 and a thumb 34, wherein the palm 80 includes a heel 82 opposite an underside of a base knuckle 84 of the illustrated index finger 26. The heel 82 and underside 84 are strong and well supported portions of the hand and accordingly play a large role in proper operation of a racquet.

(20) The illustrated hand 80 includes an index finger 26, a thumb 34, a heel 82, and an underside of a base knuckle 84. The palm of the hand 80 is configured to grip a tennis racquet handle, wherein the palm of the hand 80 adjusts and interchanges in between various grips while playing tennis or other racquet sports. The palm of the hand 80 may adjust or interchange in between a continental grip, a western grip, a semi-western grip, and an eastern grip during play. Generally, in each of these grips, the heel 82 and the underside of the base knuckle 84 will rest against the same planar surface of a racquet handle, advantageously providing control and power to the player during use of the racquet.

(21) FIG. 2 is a bottom plan view of a tennis racquet handle, according to one embodiment of the invention. Such a structure is also substantially identical to a cross-sectional view of a racquet handle taken along a plane that is parallel to a bottom surface of the racquet handle. Accordingly, herein the illustrated structure will refer both to the sides of the bottom of the handle interchangeably with the sides of the body of the handle where a hand would generally grip the same even though the bottom of the handle is generally slightly larger than a cross-section of the body. There is shown a tennis racquet handle 16 including eight sides as is typical and customary with such handles. Specifically, two of the eight sides are slightly wider than the other side sides and such wider sides are opposite to each other.

(22) Racquet handle panel numbering is generally described in the context of being right-handed or left-handed. The following description will be given in the terms of right-handed racquet grips. In particular, the eight sides are generally numbered 1-8 starting with side one 91 and going clockwise to side two 92, to side three 93, to side four 94, to side five 95, to side six 96, to side seven 97 and finally resulting in side eight 98 which is adjacent to side one 91. There are two hitting sides/faces of the racquet, the forehand hitting side 82 and the backhand hitting side 81, which are each the sides of the racquet that are facing the ball when the ball is hit. At the boundary between each adjacent side is an edge, e.g. there is an edge between sides one and two which may be identified as the first edge 83 or the one-two edge. Side three 93 is generally associated with the back-hand hitting side 81 and side seven 97 is generally associated with the forehand hitting side 82. Side three 93 and side seven 97 are substantially parallel to the racquet head and are slightly wider than the other sides. This asymmetry in side width advantageously makes it easy for a player to easily and quickly recognize the radial orientation of the racquet head by feel alone. Wherein a handle is left-handed, the numbering one to eight progresses counter-clockwise about the handle instead of clockwise. Accordingly, in a left-handed context, the sides would be as follows: side one 91 and going counter-clockwise to side two 98, to side three 97, to side four 96, to side five 95, to side six 94, to side seven 93 and finally resulting in side eight 92 which is adjacent to side one 91 (with side three 97 being the backhand hitting side and side seven 93 being the forehand hitting side).

(23) Tennis racquet grips generally require that the heel of the palm and the underside of the base knuckle of the index finger (the heel and underside are collectively referred to herein as the pads) be pressed against the same side as each other (See FIGS. 1, 3 and 4). Since a racquet is front-back symmetrical (i.e. it does not matter which side of the racquet head is used to strike the ball), there are essentially four usable panels (one through four) of a tennis racquet handle, which then correspond to eight total possible grips, in the general sense of the word grip, (four forehand grips and four backhand grips) wherein the pads are both pressed against the same side/panel of the handle but which face of the racquet is hitting the ball changes.

(24) Not all of these grips are regularly taught as some grips are more useful than others. In particular, there are five commonly taught right-handed grips (and therefore five left-handed versions of the same), specifically: the grip known as the eastern backhand grip has the pads on side one 91 and is associated with a backhand swing, the grip known as the continental grip has the pads on side two 92 and is associated with a forehand hit and with a backhand hit (thus as described herein includes two grips that have the same name), the grip known as the eastern forehand grip has the pads on side three 93 and is associated with a forehand hit (the backhand version is not generally taught), the grip known as the semi-western forehand grip has the pads on side four 94 and is associated with a forehand hit (the backhand version is not generally taught), the grip known as the full western forehand grip is generally taught as having the pads on side five 95 and is associated with a forehand hit though due to the symmetry of the handle this is essentially the same as being on side one 91 but being a forehand swing instead of the a backhand swing (i.e. the eastern backhand grip) and therefore for purposes of this description will be referred to interchangeably as pads being on side one 91 or side five 95.

(25) If the clockwise counting method for right-handed grips is used and the counterclockwise counting method for left-handed grips is used, then the above pad designations work equally well for recognizing both right and left-handed grips. Further, there are two-handed grips which are generally a combination of two of the above mentioned grips (or slight variations thereof), wherein the pads of each hand (i.e. the pads within a pad pair) are still each on the same side, though the pad pair of one hand will generally be on a different side from the pad pair of the other hand. As a non-limiting example, a two-handed backhand grip may include a continental (with the right hand) with pads on side two and an eastern forehand (with the left hand) with pads on side seven.

(26) In an alternative mode of describing the sides, the illustrated handle 16 includes a plurality of sides or panels, wherein there is a top side or panel, a left diagonal side or panel and a right diagonal side extending diagonally downwardly from opposite ends of the top side or panel. The handle 16 includes a left vertical side or panel extending downwardly from an end of the left diagonal side or panel, opposite of the top side or panel. The handle 16 includes a right vertical side or panel extending downwardly from an end of the right diagonal side or panel, opposite of the top side or panel. The handle 16 includes a bottom side or panel that is disposed directly opposite of the top side or panel, and is a mirror image thereof. The handle 16 includes a lower right diagonal side or panel extending from the right vertical side or panel and coupling to the bottom side or panel; wherein the lower right diagonal side or panel is a mirror image of the right diagonal side. The handle 16 includes a lower left diagonal side or panel extending from the left vertical side or panel and coupling to the bottom side or panel; wherein the lower left diagonal side or panel is a mirror image of the left diagonal side.

(27) FIG. 3 is a top perspective view of a hand gripping a tennis racquet handle, according to one embodiment of the invention; and FIG. 4 is a side elevational view of a hand gripping a tennis racquet handle, according to one embodiment of the invention. Each is showing a hand 80 gripping a tennis racquet handle 16.

(28) The illustrated hand 80 is gripping a tennis racquet handle 16 using a proper grip, wherein the pads are pressed against the same side/panel/face. The sides are not differentiated in FIGS. 3 and 4 in order to allow for focus on the hand position. Specifically, it may be seen that the thumb and index finger of the hand 80 forms a V-shape with the first segment of the thumb and the index finger being generally in the same plane, when disposed on the tennis racquet handle 16 in a proper grip.

(29) Advantageously, when using a proper grip, a player will have more control and power over the swing and therefore over the movement/placement of the ball. However, a proper grip is generally not the easiest way to hold the racquet and therefore it is common, especially among those first learning to play, to readjust ones grip during play to a grip that is improper without realizing it.

(30) FIG. 5 is a rear elevation view of a racquet grip teaching device, according to one embodiment of the invention and FIG. 6 is a front elevational view of a racquet grip teaching device, according to one embodiment of the invention. There is shown a racquet grip teaching device 10 including a top clasp 12 having five sides 14, a finger connector 18 that extends downwardly from the top clasp, a finger guide 22 at a far end of the finger connector, a thumb connector 28 that extends downwardly from the top clasp, and a thumb guide 32 at a far end of the thumb connector. Advantageously, the device may wrap about and be coupled to a tennis racquet handle and includes placement guides for each of the thumb and forefinger of a player's hand that force a specific position and orientation of each, thereby forcing proper placement of the pads.

(31) The illustrated racquet grip teaching device 10 selectably couples to a tennis racquet handle or any other racquet type device handle to improve grip coordination, memory, and/or muscle memory. The racquet grip teaching device 10 includes a top clasp 12 having five faces shaped and orientated to mate with a tennis racquet handle. The top clasp 12 includes a groove 42 between two adjacent interior faces. The illustrated top clasp 12 includes exactly five faces and includes at least three faces.

(32) Advantageously, a device 10, especially where it is flexible and/or includes grooves, may be coupled to a racquet handle at varying face-sets (i.e. may be removed, rotated about the handle and then attached at a different spot) and thereby a single device 10 may allow for a user to learn a plurality of grips without the need for many devices. This advantageously reduces the inventory that must be carried and reduces the space taken up by the device(s) during shipping, storage, sales, and use. As a non-limiting example, a single device 10 may be used to teach a continental grip and then, when rotated about the handle, used to teach a semi-western grip.

(33) The racquet grip teaching device 10 includes a finger connector 18 extending downwardly from the top clasp 12 at a first end region 20 of the top clasp 12.

(34) The illustrated device 10 includes a finger guide 22 disposed at an end of the finger connector 18, opposite of the top clasp 12, and may be shaped to receive a finger 26 (See FIG. 1). The illustrated finger connector 18 extends from the top clasp such that it bridges across two exterior sides of the top clasp and therefore across two exterior sides of a handle of a racquet.

(35) The illustrated racquet grip teaching device 10 includes a thumb connector 28 extending downwardly from the top clasp 12 at a second end region 30, opposite of the first end region 20. The illustrated finger connector 18 is shorter than the thumb connector 28. The thumb connector 28 and the finger connector 18 are angularly spaced apart from each other by about two and a half faces/sides of the top clasp. The illustrated thumb connector 28 is disposed flush upon an exterior side, opposite of the finger connector 18, of a tennis racquet handle. The thumb connector 28 is disposed parallel to an exterior side, opposite of the finger connector 18, of a tennis racquet handle. The racquet grip teaching device 10 includes a thumb guide 32 disposed at an end 24 of the thumb connector 28, opposite the top clasp 12, and shaped to receive a thumb 34 (See FIG. 1).

(36) The illustrated device helps players to find and keep a correct grip on a racquet. People tend to adjust to bad/improper grips and this device will help them maintain a proper grip during use. Keeping a proper grip for extended periods of practice develops muscle memory and also establishes a feel for a proper grip, changing the player so that the proper grip feels easier and more correct as opposed to a predisposition to an improper grip. The device puts the thumb and forefinger of the player in a place such that, since the thumb and forefinger have predefined relationships to the pads, the pads will be properly placed on the correct side/panel of the racquet handle.

(37) In the illustrated embodiment, each of the thumb and finger connectors extend downwardly from the top clasp at opposite locations about the top clasp and each terminate in the thumb and finger guides respectively. The clasp includes grooves that are spaced about an interior surface of the top clasp at regions between the sides thereof that mate with the sides of the racquet handle. The top clasp has five sides which produce a clasp that grips opposite sides of the racquet handle. The two connectors are spaced apart from each other by about 2.5 sides/panels/faces on the top clasp, since one connector extends from a first end side of the top clasp and is substantially planar thereto, while the opposite connector extends from a second end side opposite the first end side but also bridges the side adjacent the second end side so it is not substantially planar to the second end side.

(38) Accordingly, if one connector extends from side one of the top clasp, the other connector extends from sides four and five of the top clasp, with sides two, three and part of side four being therebetween. While FIGS. 5 and 6 illustrate the finger connector straddling two sides/faces/panels of the top clasp, it may be that the finger connector extends from only one side, while the thumb connector straddles two sides/faces/panels. The thumb and finger connectors are sized and shaped such that the pads of the hand will be pressed against the same side/face/panel of the racquet handle. In practice, this generally means that the thumb connector will be approximately the same length as the distance from the bottom of the top clasp to the bottom of the finger guide (See FIG. 7, 46).

(39) However, the exact range of length of the thumb connector is determined by the length of the finger connector, the length of the finger guide, the degree to which one connector or the other straddles two sides, the lengths of the sides of the top clasp, the length of the thumb guide and the angular orientations of each of the thumb and finger guides. Further, adjustments may also be made in determining lengths of the connectors and sizes and orientations of the guides wherein hands of a typical shapes/sizes are to be accommodated. Again, such will be selected so that the pads of the player's hands will tend to rest pressing against the same sides of the racquet handle, wherein standard grips are desired (if non-standard grips are desired, e.g. to force a handicap/difficulty on a player, such may be selected to vary from that as appropriate).

(40) According to one embodiment of the invention, there is a racquet grip teaching device/kit, that includes: a top clasp that shaped and orientated to mate with a racquet handle; a finger guide coupled to the finger connector and shaped to receive a finger; and a thumb guide coupled to the top clasp and shaped to receive a thumb. The top clasp may be a band having faces as illustrated, may be a clip, may be a connector, may be a biased member, may include a contact adhesive for coupling to a racquet handle, may be a spiral clasp that wraps up a racquet handle, may clasp in front of the racquet instead of behind as illustrated, or combinations thereof.

(41) FIG. 7 is front perspective view of a racquet grip teaching device selectably coupled to a tennis racquet handle, according to one embodiment of the invention. There is shown a racquet grip teaching device 10 including a top clasp 12, a finger connector 18, a finger guide 22, a thumb connector 28, and a thumb guide 32.

(42) The illustrated racquet grip teaching device 10 selectably couples to a tennis racquet handle 16.

The device 10 includes a finger guide 22 disposed at an end of the finger connector 18, opposite of the top clasp 12, and may be shaped to receive a finger 26 (see FIG. 1).

(43) The racquet grip teaching device 10 includes a thumb connector 28 extending downwardly from the top clasp 12 at a second end region 30, opposite of the first end region 20. The illustrated finger connector 18 is shorter than the thumb connector 28, as shown by element number 40. The relative lengths and angular positions of each of the finger connector 18 and thumb connector 28 is such that during operation, a user's base index knuckle pad and heel of hand pad are positioned on the same face (i.e. panel) of the tennis racquet handle. As used herein, the phrase heel of hand pad does not include the entire heel of the hand, but is limited to the pad on the heel that is diagonally opposite the base index knuckle pad and is not the pad at the base of the thumb. In tennis instruction, this portion of the hand is generally referred to as the heel of hand.

(44) The racquet grip teaching device 10 includes a thumb guide 32 disposed at an end of the thumb connector 28, opposite the top clasp 12, and shaped to receive a thumb 34 (See FIG. 1). At least one of the finger connector 18 or thumb connector 28 bridges two adjacent faces of the top clasp 12.

(59) The top clasp 12 includes five faces 23, 25, 27, 29, and 31 each having a groove 42 therebetween on an interior boundary between each face. The grooves 42 are regions wherein the thickness of the top clasp (i.e. the distance from the exterior surface to the interior surface) is less than the surrounding material such that the grooves 42 form a locus of increased flexibility. This advantageously permits a single device to fit multiple sizes of racquet handles. Typically, there are six adult grip/handle sizes (4, 4 and , 4 and , 4 and , 4 and , and 4 and ), two junior grip sizes (4, and 3 and ), and two children grip sizes (3 and , and 3 and ). Accordingly, instead of requiring an inventory of a total of ten different product sizes for each device, the entire range of sizes may be spanned by two to four devices, thus substantially reducing inventory costs and required storage space and shipping costs.

(60) The illustrated finger connector 18 extends orthogonally from a plane defined by the semi-circle formed by the top clasp and bridges two associated adjacent faces 23 and 25 that are opposite where the thumb connector 28 extends orthogonally from a plane defined by the semi-circle formed by the top clasp in a manner planar to the associated face 31. Accordingly, the thumb and finger guides are separated by approximately 2.5 faces

(61) The illustrated racquet grip teaching device 10 selectably couples to a tennis racquet handle or any other tennis racquet type device handle to improve grip coordination, memory, and/or muscle memory. The racquet grip teaching device 10 includes a top clasp 12 having five faces shaped and orientated to mate with a tennis racquet handle. The top clasp 12 includes a groove between two adjacent interior faces. The illustrated top clasp 12 includes exactly five faces. The racquet grip teaching device 10 includes a finger connector 18 extending downwardly from the top clasp 12 at a first end region 20 of the top clasp 12. The device 10 includes a finger guide 22 disposed at an end of the finger connector 18, opposite of the top clasp 12, and may be shaped to receive a finger 26 (See FIG. 1).

(62) The racquet grip teaching device 10 includes a thumb connector 28 extending downwardly from the top clasp 12 at a second end region 30, opposite of the first end region 20. The finger connector 18 is shorter than the thumb connector 28. The relative lengths and angular positions of each of the finger connector 18 and thumb connector 28 is such that during operation, a user's base index knuckle pad and heel of hand pad are positioned on the same face of the tennis racquet handle. The thumb connector 28 and the finger connector 18 are angularly spaced apart from each other by about two and a half faces.

(63) The racquet grip teaching device 10 includes a thumb guide 32 disposed at an end of the thumb connector 28, opposite the top clasp 12, and shaped to receive a thumb 34 (See FIG. 1). At least one of the finger connector 18 or thumb connector 28 bridges two adjacent faces of the top clasp 12.

(64) FIG. 13 is a perspective view of a racquet grip teaching kit, according to one embodiment of the invention. There is shown a racquet grip teaching kit 60 including a pair of racquet grip teaching devices 10 and a pair of elongated racquet grip teaching devices 70. The illustrated devices represent a matrix of variation along two binary variables, specifically whether the thumb or finger connector bridges two faces and whether all faces of the top clasp are substantially the same width or if one is wider 75 than the others (accommodating the wider sides three and seven of the racquet in tennis racquets). Accordingly, there is one member of the kit that has a bridging finger connector with all sides the same, one with a bridging thumb connector with all sides the same, one with a bridging finger connector with one side wider, and one with a bridging thumb connector with one side wider. A kit having all four variations will allow for a player to apply at least one device against any side of their racquet and thereby force their pads to be simultaneously against any face/side/panel of the racquet handle. Accordingly, any grip wherein the pads are against the same side is achievable with such a kit. Further, a kit may include a plurality of devices having similar characteristics (i.e. bridging and/or side width) but being of varying overall sizes, shapes, colors, and the like and combinations thereof. Additionally, varying devices may have different colors, markings, shapes, writing, protrusions, embossing and the like and combinations thereof to distinguish one from the other and/or otherwise make it easy to know which device to use for a particular grip.

(65) There is shown a racquet grip teaching kit 60 having a pair of racquet grip teaching devices 10. The illustrated racquet grip teaching device 10 selectably couples to a tennis racquet handle or any other tennis racquet type device handle to improve grip coordination, memory, and/or muscle memory. The racquet grip teaching device 10 includes a top clasp 12 having five faces shaped and orientated to mate with a tennis racquet handle. The top clasp 12 includes a groove between two adjacent interior faces. The illustrated top clasp 12 includes exactly five faces. The racquet grip teaching device 10 includes a finger connector 18 extending downwardly from the top clasp 12 at a first end region 20 of the top clasp 12. The device 10 includes a finger guide 22 disposed at an end of the finger connector 18, opposite of the top clasp 12, and may be shaped to receive a finger.

(66) The racquet grip teaching device 10 includes a thumb connector 28 extending downwardly from the top clasp 12 at a second end region 30, opposite of the first end region 20. The illustrated finger connector 18 is shorter than the thumb connector 28. The thumb connector 28 and the finger connector 18 are angularly spaced apart from each other by about two and a half faces. The thumb connector 28 is disposed flush upon an exterior side, opposite of the finger connector 18, of a tennis racquet handle. The thumb connector 28 is disposed parallel to an exterior side, opposite of the finger connector 18, of a tennis racquet handle. The racquet grip teaching device 10 includes a thumb guide 32 disposed at an end of the thumb connector 28, opposite the top clasp 12, and shaped to receive a thumb.

(67) The illustrated kit 60 includes a pair of elongated racquet grip teaching devices 70 that selectably couples to a tennis racquet handle or any other tennis racquet type device handle to improve grip coordination and memory. The elongated racquet grip teaching device 70 includes a top clasp 12 having five faces shaped and orientated to mate with a tennis racquet handle. The illustrated top clasp 12 of the elongated racquet grip teaching device 70 includes a longer middle face 75, wherein the elongated racquet grip teaching device 70 is configured to couple to a tennis racquet handle in a different position and orientation than the racquet grip teaching device 10; thereby providing interchangeability to other tennis grips for practice. The illustrated top clasp 12 includes exactly five faces. The elongated racquet grip teaching device 70 includes a finger connector 18 extending downwardly from the top clasp 12 at a first end region 20 of the top clasp 12.

The elongated racquet grip teaching device 70 includes a thumb guide 32 disposed at an end of the thumb connector 28, opposite the top clasp 12, and shaped to receive a thumb.

(69) It is understood that the above-described embodiments are only illustrative of the application of the principles of the present invention. The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiment is to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.

(70) For example, although the figures illustrate relative lengths and sizes of the structures described herein, variations on such are expected to match with varying sizes of associated racquets, varying racquet characteristics (e.g. racquets not used for tennis, racquets having fewer or more than eight panels, having panels all the same size or otherwise not sized as described herein), non-standard racquets, players having hands that substantially vary from typical sizes/shapes, and the like and combinations thereof. Further, while the description herein refers to the connectors as extending downwardly from the collar and if the device where to be inverted, such an extension may be then called upwardly but still fall within the meaning of the term downwardly as used herein since downwardly is not defined with respect to gravity or any other specific reference point.

(71) It is expected that there could be numerous variations of the design of this invention. An example is that the device may include ornamentation, branding elements, decorative flourishes and the like.

(72) Further, the top clasp may be shaped to couple to a racquet handle with the assistance of an adhesive, such as but not limited to a contact adhesive.

(73) Finally, it is envisioned that the components of the device may be constructed of a variety of materials, including but not limited to plastics, resins, gums, metals, ceramics, natural fibers, woven fibers, woods, concretes/cements, composite materials and the like and combinations thereof.

(74) Thus, while the present invention has been fully described above with particularity and detail in connection with what is presently deemed to be the most practical and preferred embodiment of the invention, it will be apparent to those of ordinary skill in the art that numerous modifications, including, but not limited to, variations in size, materials, shape, form, function and manner of operation, assembly and use may be made, without departing from the principles and concepts of the invention as set forth in the claims. Further, it is contemplated that an embodiment may be limited to consist of or to consist essentially of one or more of the features, functions, structures, methods described herein.
