Abstract
Abstract In a slingshot having reversely hooked fork arms for securement of missile-projecting elastic tubes thereto, flexible and resilient spine-like probes fastened to and extending coaxially of rearwardly directed ends the hooked fork arms to buffer, control, and limit forward fold-over of the elastic tubes over the ends of the hooked fork arms upon recoil after distention and release of the elastic tubes, whereby the tubes are protected against extreme flexure and from abrasive wear against ends of the hooked fork arms during use of the slingshot. The probes extend into the ends to a position internally of the elastic members.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
185 words
In a slingshot comprising: a handle, rod means for securing an elastic means to said handle and terminating in reversely looped rigid hook elements with free ends for attachment of elastic tubular band means thereto over said ends thereof, elastic band means for projecting a projectile, resilient spine means for protecting said elastic band means from the free ends of the hook elements and for providing an internal support and resilient mechanical restraint to preclude sharp fold-over of said band means and to prevent direct physical contact of said band means with ends of said hook elements thereby to protect said band means from both extreme flexure and abrasive wear, said spine means being attached to the free ends of said hook elements for flexing over a substantial portion of said spine means, and said spine means consisting of flexible and resilient elongated probes, each of said probes being fastened to and projecting rearwardly from a free end each of one of said elements and forming coaxial extensions thereof and disposed within said tubular band means upon attachment thereof to said elements at ends thereof.
Claim 2
Dependent Claim
185 words
In a slingshot comprising: a handle, rod means for securing an elastic means to said handle and terminating in reversely looped rigid hook elements with free ends for attachment of elastic tubular band means thereto over said ends thereof, elastic band means for projecting a projectile, resilient spine means for protecting said elastic band means from the free ends of the hook elements and for providing an internal support and resilient mechanical restraint to preclude sharp fold-over of said band means and to prevent direct physical contact of said band means with ends of said hook elements thereby to protect said band means from both extreme flexure and abrasive wear, said spine means being attached to the free ends of said hook elements for flexing over a substantial portion of said spine means, and said spine means consisting of flexible and resilient elongated probes, each of said probes being fastened to and projecting rearwardly from a free end each of one of said elements and forming coaxial extensions thereof and disposed within said tubular band means upon attachment thereof to said elements at ends thereof.
Claim 3
Dependent Claim
58 words
The improvement as set forth in claim 10 wherein said spine means includes annular wall means integrally formed with said probes and defining an open-ended socket adapted to receive an end of said hook elements therewithin for securement of said spine means to said hook elements to constitute said probes a coaxial extension of each said hook elements.
Claim 4
Dependent Claim
39 words
The improvement as set forth in claim 1 wherein said elongated flexible probe is integrally joined to a tubular body defining an open-ended socket coaxial with said probe and adapted to receive an end of a hook element therewithin.
Claim 5
Dependent Claim
44 words
The improvement as set forth in claim 1 wherein each of said probes taper along the length thereof to define a rod exhibiting progressively decreasing cross-sectional areas in a direction from a point of hook attachment to a rearwardly extending tip of said probe.
Claim 6
Dependent Claim
32 words
The improvement as set forth in claim 1 wherein said spine assembly is molded onto the end of each said hook elements in bonded relationship therewith to constitute coaxial flexible extension thereof.
Claim 7
Dependent Claim
38 words
The structure as set forth in claim 1 wherein each said hook elements is formed with an axial bore extended into an end thereof and adapted to receive and secure a plug base of said spine means therewithin.
Claim 8
Dependent Claim
41 words
The structure as set forth in claim 6 and further comprising open-ended sleeve means coaxial and connected to said probe and extending forwardly thereof for encircling and contiguously embracing and gripping a rearwardly directed end of said hook elements inserted therewithin.
Claim 9
Dependent Claim
56 words
The structure as set forth in claim 6 wherein each said hook elements is formed with a transverse opening therein extending through a wall thereof and communicating with said axial bore and wherein the base of said spine means fills said opening to key therewithin and to lock mechanically with said wall of said hook elements.
Claim 10
Dependent Claim
24 words
The structure as set forth in claim 8 wherein said spine means is molded onto the end of each one of said hook elements.
