Abstract
Abstract A racquet formed from a frame defining a head portion and merging into two end portions that constitute a handle portion. A throat member is located adjacent the merging portions. The throat member has an extension with ratchet teeth located thereon that fits between the end portions of the frame. A handle grip having interiorly located ratchet teeth fits over the end portions of the frame and the extension on the throat member. The ratchet teeth on the throat extension and the handle grip matingly engage so as to provide a secure connection between the two.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
177 words
In a racquet having a handle, a string-supporting frame having two end portions which converge toward said handle and extend longitudinally therethrough, and a throat member disposed between the converging sections of said end portions, an improved handle structure comprising: an internal handle member connected to said throat member, projecting into said handle between said end portions, and having a series of longitudinally arranged ratchet teeth; and an external handle member telescopingly received on said end portions, said external handle member having a series of longitudinally arranged ratchet teeth which are complementary to and cooperate with the ratchet teeth on said internal handle member and having space adjacent its ratchet teeth for receiving said end portions, whereby the handle is assembled by pushing said external handle member longitudinally onto said end portions so that said end portions extend into said space adjacent the ratchet teeth of said external handle member and said cooperating ratchet teeth progressively engage to lock the handle members together and firmly secure said throat member and said frame to the external handle member.
Claim 2
Dependent Claim
177 words
In a racquet having a handle, a string-supporting frame having two end portions which converge toward said handle and extend longitudinally therethrough, and a throat member disposed between the converging sections of said end portions, an improved handle structure comprising: an internal handle member connected to said throat member, projecting into said handle between said end portions, and having a series of longitudinally arranged ratchet teeth; and an external handle member telescopingly received on said end portions, said external handle member having a series of longitudinally arranged ratchet teeth which are complementary to and cooperate with the ratchet teeth on said internal handle member and having space adjacent its ratchet teeth for receiving said end portions, whereby the handle is assembled by pushing said external handle member longitudinally onto said end portions so that said end portions extend into said space adjacent the ratchet teeth of said external handle member and said cooperating ratchet teeth progressively engage to lock the handle members together and firmly secure said throat member and said frame to the external handle member.
Claim 3
Dependent Claim
55 words
A racquet according to claim 1 wherein said internal handle member has two series of outwardly directed ratchet teeth on opposite sides thereof which face outwardly between said end portions, and said external handle member has two series of inwardly directed ratchet teeth which are complementary to and cooperate with said outwardly directed ratchet teeth.
Claim 4
Dependent Claim
33 words
A racquet according to claim 2 wherein said frame has an inwardly opening groove, and said throat member has projecting tabs which engage said groove in the converging sections of said end portions.
Claim 5
Dependent Claim

A racquet according to claim 3 wherein said external handle member has a pair of sockets adjacent the bottom end thereof for retaining the terminal ends of said end portions.
Claim 6
Dependent Claim
30 words
A racquet according to claim 2 wherein said external handle member has a pair of sockets adjacent the bottom end thereof for retaining the terminal ends of said end portions.
Claim 7
Dependent Claim
29 words
A racquet according to claim 2 wherein the two series of ratchet teeth of said internal and external handle members extend generally perpendicular to the plane of the racquet.
Claim 8
Dependent Claim
33 words
A racquet according to claim 1 wherein said frame has an inwardly opening groove, and said throat member has projecting tabs which engage said groove in the converging sections of said end portions.
Claim 9
Dependent Claim
30 words
A racquet according to claim 7 wherein said external handle member has a pair of sockets adjacent the bottom end thereof for retaining the terminal ends of said end portions.
Claim 10
Dependent Claim
30 words
A racquet according to claim 1 wherein said external handle member has a pair of sockets adjacent the bottom end thereof for retaining the terminal ends of said end portions.
Claim 11
Dependent Claim
