Abstract
Abstract A handle (22) for a racquetball racquet (20) is disclosed. The handle (22) includes an elongated member having front (52), intermediate (60), and rear (50) portions. The front portion (52) defines a handle outer surface of greater circumferential extent than the rear portion (50). The front portion (52) is adapted for being engaged about a portion thereof by the two front fingers (56a, b) of a player's hand while the rear portion (50) is adapted for being gripped by the two back fingers (54a, b) of a player's hand, whereby the front (52) and rear (50) portions provide for a handle (22) which allows for a relatively hard grip by the back two fingers (54a, b) and a less hard grip by the two front fingers (56a, b) thereby allowing the wrist to relax and remain flexible so as to reduce arm stiffness and improve a player's game.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
162 words
A handle for a racquetball racquet, comprising: an elongatad member having a longitudinal axis and including front, intermediate, and rear portions, said front portion having a larger cross sectional configuration in at least two orthogonal directions than said rear portion, said intermediate portion extending from said front portion to said rear portion, said rear portion having a length which is less than said intermediate and front portions combined; said handle providing for a modified grip wherein said front portion or a portion thereof makes contact with the front two fingers of a player's hand and said rear portion or a portion thereof makes contact with the back two fingers of a player's hand, such that said front two fingers cannot extend as far about the periphery of said handle as said back fingers, and are necessarily positioned farther away from said longitudinal axis than said back fingers thereby allowing said back fingers to grip the handle more tightly than said front fingers.
Claim 2
Dependent Claim
162 words
A handle for a racquetball racquet, comprising: an elongatad member having a longitudinal axis and including front, intermediate, and rear portions, said front portion having a larger cross sectional configuration in at least two orthogonal directions than said rear portion, said intermediate portion extending from said front portion to said rear portion, said rear portion having a length which is less than said intermediate and front portions combined; said handle providing for a modified grip wherein said front portion or a portion thereof makes contact with the front two fingers of a player's hand and said rear portion or a portion thereof makes contact with the back two fingers of a player's hand, such that said front two fingers cannot extend as far about the periphery of said handle as said back fingers, and are necessarily positioned farther away from said longitudinal axis than said back fingers thereby allowing said back fingers to grip the handle more tightly than said front fingers.
Claim 3
Dependent Claim
23 words
A racquetball racquet handle in accordance with claim 1 wherein said front portion is provided with indentations for positioning said two front fingers.
Claim 4
Dependent Claim
21 words
A racquetball racquet handle in accordance with claim 2 wherein each of said finger indentations are separated by a contoured protuberance.
Claim 5
Dependent Claim
39 words
A handle for a racquetball racquet in accordance with claim 1, wherein said forward, intermediate and rear portions have cross-sectional configurations being generally symmetrical on either side of a vertical plane bisecting said longitudinal axis of said elongated member.
Claim 6
Dependent Claim
28 words
A handle for a racquetball racquet in accordance with claim 1, wherein said outer surfaces of said front and rear portions are substantially parallel to said longitudinal axis.
Claim 7
Dependent Claim
20 words
A handle for a racquetball racquet in accordance with claim 1, wherein said intermediate portion has a generally conical shape.
Claim 8
Dependent Claim
29 words
A handle for a racquetball racquet in accordance with claim 1, wherein said outer surface of said front portion is inclined downwards at both ends of said forward portion.
Claim 9
Dependent Claim
24 words
A handle for a racquetball racquet in accordance with claim 1, wherein said front and intermediate portions are radially symmetrical about said longitudinal axis.
Claim 10
Dependent Claim
194 words
A gripping attachment for a racquetball racquet handle comprising: a finger gripping structure constructed and arranged for at least partially encircling the circumference of said handle; said gripping attachment being removably attachable to said handle so as to form an elongated member having a longitudinal axis and including front, intermediate and rear portions; said front portion having a larger cross sectional configuration in at laast two orthogonal directions than said rear portion; said intermediate portion extending from said front portion to said rear portion; said rear portion having a length which is less than said intermediate and forward portions combined; said handle providing for a modified grip wherein said front portion or a portion thereof makes contact with the front two fingers of a player's hand and said rear portion or a portion thereof makes contact with the back two fingers of a player's hand, such that said front two fingers cannot extend as far about the periphery of said handle as said back fingers, and are necessarily positioned farther away from said longitudinal axis than said back fingers thereby allowing said back fingers to grip the handle more tightly than said front fingers.
Claim 11
Dependent Claim
194 words
A gripping attachment for a racquetball racquet handle comprising: a finger gripping structure constructed and arranged for at least partially encircling the circumference of said handle; said gripping attachment being removably attachable to said handle so as to form an elongated member having a longitudinal axis and including front, intermediate and rear portions; said front portion having a larger cross sectional configuration in at laast two orthogonal directions than said rear portion; said intermediate portion extending from said front portion to said rear portion; said rear portion having a length which is less than said intermediate and forward portions combined; said handle providing for a modified grip wherein said front portion or a portion thereof makes contact with the front two fingers of a player's hand and said rear portion or a portion thereof makes contact with the back two fingers of a player's hand, such that said front two fingers cannot extend as far about the periphery of said handle as said back fingers, and are necessarily positioned farther away from said longitudinal axis than said back fingers thereby allowing said back fingers to grip the handle more tightly than said front fingers.
Claim 12
Independent Claim
90 words
A method of gripping a racquetball racquet handle, comprising the steps of: (a) positioning the back two fingers at least partially about the circumference of a first longitudinal portion of the handle; and (b) positioning the front two fingers at least partially about the circumference of a second longitudinal portion of the handle, said second portion having a larger cross section than said first portion whereby the larger cross section of said second portion prevents the front two fingers from gripping the handle as tightly as the back two fingers.
Claim 13
Independent Claim
90 words
A method of gripping a racquetball racquet handle, comprising the steps of: (a) positioning the back two fingers at least partially about the circumference of a first longitudinal portion of the handle; and (b) positioning the front two fingers at least partially about the circumference of a second longitudinal portion of the handle, said second portion having a larger cross section than said first portion whereby the larger cross section of said second portion prevents the front two fingers from gripping the handle as tightly as the back two fingers.
