Abstract

Abstract A hand weapon that appears to be in innocuous key carrying device. The device includes a hollow handle member having a removable end cap to which a number of keys are connected through an axially movable plunger that passes through the cap into the interior of the handle. The inner end of the plunger is secured to one end of a relatively long cord normally stored in the handle, and the other end of the cord is secured to the handle itself. Coacting means are provided on the plunger and handle for releasably holding the end cap in position on the handle but the user can release the end cap which permits the keys to be hurled at an attacker.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 169 words
A self defense weapon comprising a hollow handle member, an end cap removably mounted on one end of the handle member, plunger means extending through the cap, a ring for receiving keys connected to the plunger means outside the end cap, an elongated flexible element of substantially greater length than the handle member normally stored in the interior of the member, one end of the flexible element being secured to the handle member and the other end thereof being secured to the plunger means inside the end cap, and coacting means on the handle member and plunger means for releasably holding the end cap in position on the handle member, the end cap being movable axially to remove it from the handle member whereby the plunger means and keys on the ring can be hurled at an attacker, the plunger means and keys travelling outwardly to the extent permitted by the full length of the flexible element which is withdrawn from the handle member by the attached plunger means.
Claim 2
Dependent Claim 169 words
A self defense weapon comprising a hollow handle member, an end cap removably mounted on one end of the handle member, plunger means extending through the cap, a ring for receiving keys connected to the plunger means outside the end cap, an elongated flexible element of substantially greater length than the handle member normally stored in the interior of the member, one end of the flexible element being secured to the handle member and the other end thereof being secured to the plunger means inside the end cap, and coacting means on the handle member and plunger means for releasably holding the end cap in position on the handle member, the end cap being movable axially to remove it from the handle member whereby the plunger means and keys on the ring can be hurled at an attacker, the plunger means and keys travelling outwardly to the extent permitted by the full length of the flexible element which is withdrawn from the handle member by the attached plunger means.
Claim 3
Dependent Claim 18 words
A weapon as defined in claim 1 wherein the elongated flexible element is a length of nylon cord.
Claim 4
Dependent Claim 47 words
A weapon as defined by claim 1 wherein the plunger means comprises an elongated rod element that is movable axially relative to the end cap between inner and outer limiting positions, and spring means on the rod element for biasing it outwardly towards its outer limiting position.
Claim 5
Dependent Claim 73 words
A weapon as defined by claim 3 wherein the coacting means for releasably holding the end cap in position comprises flange means adjacent the inner end of the rod element and a keeper on the handle member that releasably engages said flange means, the keeper normally being held in engagement with the flange means by the end cap, the cap being movable axially to permit disengagement of the keeper from the flange means.
Claim 6
Dependent Claim 28 words
A weapon as defined by claim 4 wherein the spring means also operates to releasably hold the rod element flange and handle keeper in engagement with one another.
Claim 7
Dependent Claim 228 words
A self defense weapon comprising a tubular handle member, a first end cap fixed on one end of the handle member, a second end cap removably mounted on the other end of the handle member, a plunger element extending through the second end cap and being movable axially relative thereto, a ring for receiving a plurality of keys, the ring being connected to the plunger element adjacent its outer end outside the second end cap, a compression spring mounted on the plunger element between the second end cap and key ring, flange means adjacent the inner end of the plunger element inside the second end cap, an elongated flexible element of substantially greater length than the handle member normally stored in the interior of the member, one end of the flexible element being secured to the handle member and the other end thereof being secured to the inner end of the plunger element, and keeper means on the handle member that coacts with the plunger flange means to releasably hold the second end cap in position on the handle member, the second end cap being movable axially to remove it from the handle member whereby the plunger element and keys on the ring can be hurled at an attacker, the plunger element and keys travelling outwardly to the extent permitted by the full length of the flexible element.
Claim 8
Dependent Claim 228 words
A self defense weapon comprising a tubular handle member, a first end cap fixed on one end of the handle member, a second end cap removably mounted on the other end of the handle member, a plunger element extending through the second end cap and being movable axially relative thereto, a ring for receiving a plurality of keys, the ring being connected to the plunger element adjacent its outer end outside the second end cap, a compression spring mounted on the plunger element between the second end cap and key ring, flange means adjacent the inner end of the plunger element inside the second end cap, an elongated flexible element of substantially greater length than the handle member normally stored in the interior of the member, one end of the flexible element being secured to the handle member and the other end thereof being secured to the inner end of the plunger element, and keeper means on the handle member that coacts with the plunger flange means to releasably hold the second end cap in position on the handle member, the second end cap being movable axially to remove it from the handle member whereby the plunger element and keys on the ring can be hurled at an attacker, the plunger element and keys travelling outwardly to the extent permitted by the full length of the flexible element.
Claim 9
Dependent Claim 32 words
A weapon as defined in claim 6 wherein the elongated flexible element is a length of nylon cord, the cord length being at least four times the length of the handle member.
Claim 10
Dependent Claim 116 words
A weapon as defined in claim 6 wherein the keeper means is a flexible plastic strip secured at one end to the end of the handle member adjacent the first end cap, the strip extending longitudinally along the outside of the handle member to a point adjacent the second cap where the member is formed with a hole in its side wall, the strip having a protuberance at that point which projects through the hole and engages the plunger flange means, the second end cap when mounted on the handle member operating to hold the protuberance in the hole and the compression spring in turn operating to urge the flange means into engagement with the protuberance.
