Abstract

Abstract A handle construction for racquets having opposing, flat ball-striking playing faces wherein the handle is of substantially octagonal outline of varying sized opposing surfaces, one pair of which are parallel to the playing faces of the racquet, the size variation between these opposing surfaces and other pairs of opposing surfaces among the composite surfaces of the handle are different to the degree that they are sensorially perceptive by sense of feel transmitted by impression gained only in the hand grip of the player without other observation. The determination of these surfaces involved at one or more of the corners of the handle's sectional outline is intensified to be more acute to the feel than the ordinary corner of a handle of normally octagonal outline of 135° and more acute than nonrecessed or other corners, as to provide extra sensory perception felt through the player's grip only, as to the disposition of the playing faces throughout an entire swing of the racquet without prior or instant observation or other prior orientative discernment. A handle construction of tennis racquet character having extra sensory perception incorporated in the handle's perimeter surfaces as to their composite differences in size, shape and intensification of the corners or other elements comprising its cross-sectional outline including its girth and diametrical dimensional differences among the opposing pairs of surfaces.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 176 words
In a tennis racquet of the character described having a playing face adapted for ball-striking, a longitudinal octagonal-like handle providing a pair of parallel and opposed grip-embracable longitudinal surfaces spaced apart and parallel to the plane of said ball-striking surfaces, and another pair of spaced, opposed and parallel grip-embracable longitudinal surfaces at right angles to the first mentioned pair, the transverse distance between the surfaces of the first mentioned pair of surfaces being less than 84% of the transverse distances between the surfaces of the second mentioned pair, whereupon gripping of the handle, the said difference in said transverse distances between the said pairs of surfaces is sensibly perceptive and mentally impressive upon the grip of the player, whereby the disposition of the handle and the ball-striking surface is orientatively discerned before the players stroke without observation or physical contact with the racquet other than by a single-hand grip, and also whereby the said distance difference discernment is retained throughout the players stroke and diametrically opposed scollups each extending along an edge of its containing surface.
Claim 2
Dependent Claim 176 words
In a tennis racquet of the character described having a playing face adapted for ball-striking, a longitudinal octagonal-like handle providing a pair of parallel and opposed grip-embracable longitudinal surfaces spaced apart and parallel to the plane of said ball-striking surfaces, and another pair of spaced, opposed and parallel grip-embracable longitudinal surfaces at right angles to the first mentioned pair, the transverse distance between the surfaces of the first mentioned pair of surfaces being less than 84% of the transverse distances between the surfaces of the second mentioned pair, whereupon gripping of the handle, the said difference in said transverse distances between the said pairs of surfaces is sensibly perceptive and mentally impressive upon the grip of the player, whereby the disposition of the handle and the ball-striking surface is orientatively discerned before the players stroke without observation or physical contact with the racquet other than by a single-hand grip, and also whereby the said distance difference discernment is retained throughout the players stroke and diametrically opposed scollups each extending along an edge of its containing surface.
Claim 3
Dependent Claim 39 words
A tennis racquet according to claim 1 wherein the cross-sectional outline of the said handle is of substantially octagonal configuration with eight corners and wherein at least two dimetrically opposite corners are more acute than the other six corners.
Claim 4
Dependent Claim 41 words
A tennis racquet according to claim 1 wherein the cross-sectional outline of the said handle is of substantially octagonal configuration with eight corners and wherein at least four corners in two opposite pairs are more acute than the other four corners.
Claim 5
Dependent Claim 41 words
A tennis racquet according to claim 1 wherein the cross-sectional outline of the said handle is of substantially octagonal configuration with eight corners and wherein six corners in three diametrically opposite pairs are more acute than the remaining opposite two corners.
Claim 6
Dependent Claim 133 words
A tennis racquet handle of the character described of octagonal-like cross-sectional outline comprising a plurality of pairs of substantially diametrically opposite surfaces, the surfaces of each pair being of similar width and forming obtuse edges of substantially 135° subtended angle defining said outline, a single longitudinal flute-like depression in each surface of at least one of said pairs of surfaces, said flute-like depressions being oppositely and so disposed in their respective surfaces as to form at least two diametrically opposite continuously longitudinal edges more acute than said 135° edges, the edges of adjacent pairs of surfaces of said octagonal outline being of different distances apart, whereupon gripping of the handle, the orientative disposition of the said more acute edges are perceivable by only the sense of feel in the grip of a player.
Claim 7
Dependent Claim 133 words
A tennis racquet handle of the character described of octagonal-like cross-sectional outline comprising a plurality of pairs of substantially diametrically opposite surfaces, the surfaces of each pair being of similar width and forming obtuse edges of substantially 135° subtended angle defining said outline, a single longitudinal flute-like depression in each surface of at least one of said pairs of surfaces, said flute-like depressions being oppositely and so disposed in their respective surfaces as to form at least two diametrically opposite continuously longitudinal edges more acute than said 135° edges, the edges of adjacent pairs of surfaces of said octagonal outline being of different distances apart, whereupon gripping of the handle, the orientative disposition of the said more acute edges are perceivable by only the sense of feel in the grip of a player.
Claim 8
Dependent Claim 45 words
A tennis racquet handle in accordance with claim 5, wherein the said flute-like depressions each, spans its containing surface from edge to edge and forms at their terminations four edges each more acute than said obtuse edges along diametrically opposite edges of said octagonal-like outline.
Claim 9
Dependent Claim 35 words
A tennis racquet handle in accordance with claim 5, wherein each of the diagonal pairs of surfaces of said octagonal-like outline is of different transverse width than that of its adjacent pair of opposite surfaces.
Claim 10
Dependent Claim 28 words
A tennis racquet handle in accordance with claim 5, wherein all of the said surfaces are fluted edge to edge, forming edges acuter than 135° of subtended angle.
Claim 11
Dependent Claim 26 words
A tennis racquet in accordance with claim 5, wherein only one of said pairs of opposite surfaces are of different perimetrical width than the other pairs.
