Abstract
Abstract There is disclosed herein a game racket having a frame formed from a single length of tubular framing shaped into an oval and having parallel extensions for the handle. The extensions are provided with connectors which space the extensions a fixed distance apart and provide interlocking means for securing the extensions to each other. Handgrip means in the form of two complementary sections encase distal end portions of the extensions and the connectors to provide a grip for the racket.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
184 words
Handle structure for a game racket, said handle structure comprising a pair of parallel, laterally spaced extensions affording a handle for the racket, said extensions having laterally outwardly facing side edges and front and back surfaces disposed generally at right angles with respect to said side edges; connector means laterally connecting said extensions and maintaining said extensions in spaced relationship; a pair of complementary handgrip sections, each section having means providing spaced, parallel, elongated recesses disposed lengthwise of the section, and an elongated central rib projecting between said extensions; said sections being disposed over said front and back surfaces of said pair of extensions, distal end portions of said extensions nesting within said elongated recesses; means defining cutout means in said rib; said connector means projecting laterally through said cutout means; said extensions having dovetail shaped, longitudinal groove means opening inwardly toward each other; said connector means having oppositely disposed dovetail shaped portions interfitting said longitudinal groove means; said connector means having enlarged spacer means disposed between said dovetail shaped portions outwardly of said groove means for maintaining a fixed spacing between said extensions.
Claim 2
Dependent Claim
184 words
Handle structure for a game racket, said handle structure comprising a pair of parallel, laterally spaced extensions affording a handle for the racket, said extensions having laterally outwardly facing side edges and front and back surfaces disposed generally at right angles with respect to said side edges; connector means laterally connecting said extensions and maintaining said extensions in spaced relationship; a pair of complementary handgrip sections, each section having means providing spaced, parallel, elongated recesses disposed lengthwise of the section, and an elongated central rib projecting between said extensions; said sections being disposed over said front and back surfaces of said pair of extensions, distal end portions of said extensions nesting within said elongated recesses; means defining cutout means in said rib; said connector means projecting laterally through said cutout means; said extensions having dovetail shaped, longitudinal groove means opening inwardly toward each other; said connector means having oppositely disposed dovetail shaped portions interfitting said longitudinal groove means; said connector means having enlarged spacer means disposed between said dovetail shaped portions outwardly of said groove means for maintaining a fixed spacing between said extensions.
Claim 3
Dependent Claim
227 words
Handle structure for a game racket, said handle structure comprising a pair of parallel, laterally spaced extensions affording a handle for the racket, said extensions having outwardly and inwardly facing side edges and laterally disposed surface portions including front and back surfaces; connector means comprising a spacer portion disposed between said inwardly facing side edges of said extensions for maintaining said extensions in spaced relationship; said spacer portion having protrusions projecting therefrom in opposite directions; said extensions having groove means formed in said inwardly facing side edges for receiving said protrusions; said groove means having a bottom portion of greater dimension in transverse section than the opening thereof at said inwardly facing side edges; said protrusions being of greater dimension at their outermost ends than portions spaced inwardly of said outermost ends as seen in transverse section whereby said protrusions engage and interlock with said groove means; a pair of complementary handgrip sections, each section having an elongated central rib projecting parallel with and between said extensions and portions overlapping said laterally disposed surface portions and providing a handgrip; said ribs having cutout means therein and said connector means projecting laterally through said cutout means; and said spacer portion projecting perpendicular to the plane of said extensions beyond the opening of said groove means at said inwardly facing side edges and spacing said extensions from each other.
Claim 4
Dependent Claim
227 words
Handle structure for a game racket, said handle structure comprising a pair of parallel, laterally spaced extensions affording a handle for the racket, said extensions having outwardly and inwardly facing side edges and laterally disposed surface portions including front and back surfaces; connector means comprising a spacer portion disposed between said inwardly facing side edges of said extensions for maintaining said extensions in spaced relationship; said spacer portion having protrusions projecting therefrom in opposite directions; said extensions having groove means formed in said inwardly facing side edges for receiving said protrusions; said groove means having a bottom portion of greater dimension in transverse section than the opening thereof at said inwardly facing side edges; said protrusions being of greater dimension at their outermost ends than portions spaced inwardly of said outermost ends as seen in transverse section whereby said protrusions engage and interlock with said groove means; a pair of complementary handgrip sections, each section having an elongated central rib projecting parallel with and between said extensions and portions overlapping said laterally disposed surface portions and providing a handgrip; said ribs having cutout means therein and said connector means projecting laterally through said cutout means; and said spacer portion projecting perpendicular to the plane of said extensions beyond the opening of said groove means at said inwardly facing side edges and spacing said extensions from each other.
Claim 5
