Abstract

Abstract A tennis racket or other striking implement for minimizing the shock imparted to the arm of the user, having a head or striking portion and a handle portion provided with a longitudinal slot lying in a plane substantially parallel to the striking face, said handle having a longitudinal hole in the end thereof remote from the striking head to accommodate an insert of resilient elastic material slightly larger than the hole diameter such as to produce spreading of the parts of the handle on either side of the slot when the insert is introduced into the hole, and a grip-enhancing binding on the handle applied in a manner to urge the two parts of the handle together and to compress the insert. Preferably the insert is of highly compressed rubber, but it may comprise natural or synthetic rubber. The invention may be applied to striking implements having handles made of wood as well as to those having tubular handles of metal, fiber glass or other materials.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 298 words
A tennis racket incorporating means for minimizing shock imparted to the arm of a user, comprising: (a) a head portion, (b) an elongated handle affixed to said head portion and including a gripping portion near the end thereof remote from said head portion, said handle consisting of a single longitudinal slot therein lying in a plane substantially parallel to that of said head portion, extending part of the length of said handle from the end thereof farthest from said head and laterally through said handle so as to divide said handle into two unitary parts and so as to permit longitudinal movement of said parts relative to each other, and said gripping portion having a longitudinal hole in the distal end thereof remote from said head portion and extending a part of the length of said gripping portion, said hole being of substantially uniform cross section throughout its length, wherein its length is substantially the same as the length of an object inserted therein, and having bounding surfaces substantially free from obstructions so that an object inserted therein is free to move in relation to said surfaces subject only to frictional forces exerted between said surfaces and said object whenever longitudinal movement between said parts of said handle occurs when an object is struck with said racket, (c) an insert of resilient elastic material contained in said hole, said insert having a dimension transverse to the longitudinal axis of said handle which is somewhat larger than the transverse dimension of said hole prior to insertion thereof, such as to spread the parts of said handle upon insertion, and (d) a grip-enhancing binding applied to the exterior of said gripping portion in a manner to urge the parts of said handle toward each other and to compress said insert.
Claim 2
Dependent Claim 298 words
A tennis racket incorporating means for minimizing shock imparted to the arm of a user, comprising: (a) a head portion, (b) an elongated handle affixed to said head portion and including a gripping portion near the end thereof remote from said head portion, said handle consisting of a single longitudinal slot therein lying in a plane substantially parallel to that of said head portion, extending part of the length of said handle from the end thereof farthest from said head and laterally through said handle so as to divide said handle into two unitary parts and so as to permit longitudinal movement of said parts relative to each other, and said gripping portion having a longitudinal hole in the distal end thereof remote from said head portion and extending a part of the length of said gripping portion, said hole being of substantially uniform cross section throughout its length, wherein its length is substantially the same as the length of an object inserted therein, and having bounding surfaces substantially free from obstructions so that an object inserted therein is free to move in relation to said surfaces subject only to frictional forces exerted between said surfaces and said object whenever longitudinal movement between said parts of said handle occurs when an object is struck with said racket, (c) an insert of resilient elastic material contained in said hole, said insert having a dimension transverse to the longitudinal axis of said handle which is somewhat larger than the transverse dimension of said hole prior to insertion thereof, such as to spread the parts of said handle upon insertion, and (d) a grip-enhancing binding applied to the exterior of said gripping portion in a manner to urge the parts of said handle toward each other and to compress said insert.
Claim 3
Dependent Claim 315 words
A striking implement incorporating means for minimizing shock imparted to the arm of a user, comprising: (a) a head portion having a striking face adapted to engage an object to be struck, (b) an elongated handle affixed to said head portion and having an axis substantially parallel to said striking face, said handle consisting of a single longitudinal slot therein lying in a plane substantially parallel to the plane of said striking face, extending at least part of the length of said handle from the end thereof farthest from said head portion and laterally through said handle so as to divide said handle into two unitary parts and so as to permit longitudinal movement of said parts relative to each other, and said handle having a longitudinal hole in the distal end thereof remote from said head portion and extending part of the length of said handle, said hole being of substantially uniform cross section throughout its length, wherein its length is substantially the same as the length of an object inserted therein, and having bounding surfaces substantially free from obstructions so that an object inserted therein is free to move in relation to said surfaces subject only to frictional forces exerted between said surfaces and said object whenever longitudinal movement between said parts of said handle occurs when an object is struck with said implement, (c) an insert of resilient elastic material contained in said hole, said insert having a dimension transverse to the longitudinal axis of said handle which is somewhat larger than the transverse dimension of said hole prior to insertion thereof, such as to spread the parts of said handle upon insertion, and (d) a grip-enhancing binding applied to the exterior of said handle near the end thereof farthest from said head portion in a manner to urge the parts of said handle toward each other and to compress said insert.
Claim 4
Dependent Claim 315 words
A striking implement incorporating means for minimizing shock imparted to the arm of a user, comprising: (a) a head portion having a striking face adapted to engage an object to be struck, (b) an elongated handle affixed to said head portion and having an axis substantially parallel to said striking face, said handle consisting of a single longitudinal slot therein lying in a plane substantially parallel to the plane of said striking face, extending at least part of the length of said handle from the end thereof farthest from said head portion and laterally through said handle so as to divide said handle into two unitary parts and so as to permit longitudinal movement of said parts relative to each other, and said handle having a longitudinal hole in the distal end thereof remote from said head portion and extending part of the length of said handle, said hole being of substantially uniform cross section throughout its length, wherein its length is substantially the same as the length of an object inserted therein, and having bounding surfaces substantially free from obstructions so that an object inserted therein is free to move in relation to said surfaces subject only to frictional forces exerted between said surfaces and said object whenever longitudinal movement between said parts of said handle occurs when an object is struck with said implement, (c) an insert of resilient elastic material contained in said hole, said insert having a dimension transverse to the longitudinal axis of said handle which is somewhat larger than the transverse dimension of said hole prior to insertion thereof, such as to spread the parts of said handle upon insertion, and (d) a grip-enhancing binding applied to the exterior of said handle near the end thereof farthest from said head portion in a manner to urge the parts of said handle toward each other and to compress said insert.
Claim 5
Dependent Claim 14 words
A striking implement according to claim 2 in which said insert comprises compressed rubber.
Claim 6
Dependent Claim 23 words
A striking implement according to claim 2 in which said slot is substantially coextensive in length with said gripping portion of said handle.
Claim 7
Dependent Claim 38 words
A striking implement according to claim 2 in which the depth of said hole is substantially the same as the length of said insert so that the insert contacts both the side and the bottom of said hole.
Claim 8
