Abstract
Abstract A hand-held device for personal protection. The device is provided with a hook at the end of a rod. When it is desired to strike at an attacker, the hook is thrust from within the housing of the device. The device can be provided with compression bias which requires a user to apply pressure to a knob to actuate the device or with a tension bias which permits the device to be actuated upon the release of a trigger-type arrangement.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
131 words
A hand-held non-lethal personal defense and fishing device comprising an elongated housing, an axial longitudinal bore extending through at least a portion of said housing, a slidably reciprocable rod axially disposed in said axial longitudinal bore of said housing, a single hook member projecting from one end of said rod, said hook member being in the form of a fishing hook having at least three substantially evenly disposed barbs, means for directly attaching said hook member to said one end of said rod, and rod displacing means provided proximate the other end of said rod, wherein actuation of said rod displacing means longitudinally displaces said rod from an inoperative position whereby said hook member is disposed within said housing to an inoperative position whereby said hook member projects from said housing.
Claim 2
Dependent Claim
131 words
A hand-held non-lethal personal defense and fishing device comprising an elongated housing, an axial longitudinal bore extending through at least a portion of said housing, a slidably reciprocable rod axially disposed in said axial longitudinal bore of said housing, a single hook member projecting from one end of said rod, said hook member being in the form of a fishing hook having at least three substantially evenly disposed barbs, means for directly attaching said hook member to said one end of said rod, and rod displacing means provided proximate the other end of said rod, wherein actuation of said rod displacing means longitudinally displaces said rod from an inoperative position whereby said hook member is disposed within said housing to an inoperative position whereby said hook member projects from said housing.
Claim 3
Dependent Claim
16 words
The device of claim 1 further comprising biasing means urging said rod toward said inoperative position.
Claim 4
Dependent Claim
22 words
The device of claim 1 wherein said rod displacing means comprises a push member coupled to said other end of said rod.
Claim 5
Dependent Claim
22 words
The device of claim 2 wherein said rod displacing means comprises a push member coupled to said other end of said rod.
Claim 6
Dependent Claim
47 words
The device of claim 4 wherein said biasing means urging said rod toward said inoperative position comprises a compression spring disposed around said rod, said spring having one end abutting an end surface of said push member and another end abutting an end surface of said housing.
Claim 7
Dependent Claim
67 words
The device of claim 1 wherein said rod displacing means comprises biasing means urging said rod toward said operative position and holding means manually displaceable from a first position wherein said holding means prevents said rod from being urged toward said operative position by said biasing means to a second position wherein said rod is free to be urged toward said operative position by said biasing means.
Claim 8
Dependent Claim
130 words
The device of claim 6 wherein said biasing means urging said rod towards said operative position comprises a handle member affixed to an end surface of said housing, a radial bore in said handle member extending through the exterior surface of said handle member such as to form an opening, said radial bore in said handle member being aligned with said axial longitudinal bore in said housing, said radial bore in said handle member slidably accepting an end portion of said rod passed through said opening, a compression spring disposed in said radial bore of said handle member with the ends of said compression spring disposed between a closed end of said radial bore of said handle member and an end cap affixed to said end portion of said rod.
Claim 9
Dependent Claim
199 words
The device of claim 6 wherein said holding means comprises a transverse bore in said housing, said transverse bore forming an opening through one side of said housing, said transverse bore having a relatively small diameter portion proximate said opening and a large diameter portion, an elongated release member slidably disposed in said small diameter portion of said transverse bore, one end of said release member protruding through said opening and the other end of said release member abutting a spring-loaded plunger disposed in said relatively large diameter portion of said transverse bore, and an engagement member protruding substantially at right angle from the exterior surface of said release member wherein said spring-loaded plunger urges said engagement member protruding from said release member into engagement with a notch in said rod when said holding means is in said first position and wherein said holding means is displaced to said second position by applying pressure to said one end of said release member protruding through said opening of said housing which thereby displaces said other end of said release member against said spring-loaded plunger and disengages said engagement member protruding from said release member from said notch in said rod.
Claim 10
Dependent Claim
128 words
The device of claim 8 wherein said means for attaching said hook member to said one end of said rod comprises a transverse longitudinal slot provided through a portion of said rod, said transverse longitudinal slot forming an opening at said one end of said rod for inserting a sheath into said slot, an end of said sheath being affixed to an end portion of said hook member, a transverse bore being provided through said sheath proximate the other end of said sheath, aligned transverse bores in said rod, said aligned transverse bores in said rod communicating with said slot in said rod, and a pin member passed through said aligned transverse bores in said rod and through said transverse bore in said sheath inserted in said slot.
Claim 11
Dependent Claim
28 words
The device of claim 1 wherein said hook member separates from said one end of said rod upon a predetermined amount of pull being applied to said rod.
Claim 12
Dependent Claim
77 words
The device of claim 1 further comprising an integral lip protruding at substantially right angle from the exterior surface of a portion of said rod, a longitudinal groove in said housing, said longitudinal groove in said housing being in communication with and extending along a portion of said axial longitudinal bore of said housing, said lip being slidably engaged within said longitudinal groove in said housing to hold said rod against rotation in said axial longitudinal bore.
