Abstract
Abstract A survival kit is disclosed which is based on a hollow tubular member which serves both as the main body of a collapsible cross-bow and as a container for the component parts of the cross-bow and other survival equipment. The preferred embodiment of the elements of the collapsible cross-bow are described and a preferred trigger mechanism for the cross-bow is disclosed.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
213 words
A survival kit comprising an elongated hollow tubular body of circular cross-section closed at one end by a solid plug, a cap removably sealing the other end of said hollow tubular body water-tight to provide a sealed container of given length, a pair of resilient arms of equal length less than said given length of said sealed container, means removably mounting one end of each of said pair of arms in said solid plug at said one end of said elongated hollow tubular body with said arms extending normally to the axis of said hollow tubular body in a common plane on opposite sides thereof, a bowstring having its opposite ends each removably mounted under tension at the free end of a different one of said pair of resilient arms, and a trigger mechanism releasably holding said bowstring under tension with said resilient arms flexed removably mounted on the exterior of said hollow tubular body at a point spaced along said elongated tubular body from said plug closing said one end thereof in a plane normal to said plane in which said pair of arms extend, whereby said arms, said bowstring and said trigger mechanism may be removed and received within said sealed container provided by said elongated hollow body and said cap.
Claim 2
Dependent Claim
213 words
A survival kit comprising an elongated hollow tubular body of circular cross-section closed at one end by a solid plug, a cap removably sealing the other end of said hollow tubular body water-tight to provide a sealed container of given length, a pair of resilient arms of equal length less than said given length of said sealed container, means removably mounting one end of each of said pair of arms in said solid plug at said one end of said elongated hollow tubular body with said arms extending normally to the axis of said hollow tubular body in a common plane on opposite sides thereof, a bowstring having its opposite ends each removably mounted under tension at the free end of a different one of said pair of resilient arms, and a trigger mechanism releasably holding said bowstring under tension with said resilient arms flexed removably mounted on the exterior of said hollow tubular body at a point spaced along said elongated tubular body from said plug closing said one end thereof in a plane normal to said plane in which said pair of arms extend, whereby said arms, said bowstring and said trigger mechanism may be removed and received within said sealed container provided by said elongated hollow body and said cap.
Claim 3
Dependent Claim
32 words
A survival kit as claimed in claim 1 including an arrow having a length less than said given length of said sealed container provided by said elongated hollow body and said cap.
Claim 4
Dependent Claim
17 words
A survival kit as claimed in claim 1 wherein said cap comprises an elongated tubular cup-like member.
Claim 5
Dependent Claim
65 words
A survival kit as claimed in claim 3 wherein said length of each of said pair of resilient arms is substantially equal to the length of said hollow elongated tubular body and said hollow elongated tubular body is dimensioned to receive said arms, said trigger mechanism and said bowstring with said elongated tubular cup-like cap means being dimensioned to receive other items of survival equipment.
Claim 6
Dependent Claim
69 words
A survival kit as claimed in claim 1 wherein said means removably mounting one end of each of said pair of arms on said solid plug at said one end of said elongated hollow tubular body comprises external threads on said one end of each of said pair of resilient arms and a threaded passageway through said solid plug closing said one end of said elongated hollow tubular body.
Claim 7
Dependent Claim
46 words
A survival kit as claimed in claim 5 wherein said elongated hollow tubular body and said solid plug closing said one end thereof are integral with each other and together with said cap, said pair of resilient arms and said trigger mechanism are made of aluminum.
Claim 8
Dependent Claim
140 words
A collapsible cross-bow comprising an elongated body of given length, a pair of resilient arms each having a length less than said given length and each provided with an externally threaded portion of circular cross-section at one end thereof, a tapped passageway of circular-cross section through said elongated body at one end thereof threadedly engaging said externally threaded portions of each of said arms at opposite ends thereof, a bowstring having its opposite ends each removably mounted under tension at the free end of a different one of said pair of resilient arms, and a trigger mechanism releasably holding said bowstring under tension with said resilient arms flexed removably mounted on the external surface of said elongated body at a point spaced along said body from said tapped passageway in a plane normal to the axis of said tapped passageway.
Claim 9
Dependent Claim
140 words
A collapsible cross-bow comprising an elongated body of given length, a pair of resilient arms each having a length less than said given length and each provided with an externally threaded portion of circular cross-section at one end thereof, a tapped passageway of circular-cross section through said elongated body at one end thereof threadedly engaging said externally threaded portions of each of said arms at opposite ends thereof, a bowstring having its opposite ends each removably mounted under tension at the free end of a different one of said pair of resilient arms, and a trigger mechanism releasably holding said bowstring under tension with said resilient arms flexed removably mounted on the external surface of said elongated body at a point spaced along said body from said tapped passageway in a plane normal to the axis of said tapped passageway.
Claim 10
Dependent Claim
61 words
A collapsible cross-bow as claimed in claim 7 wherein said elongated body is provided with a semicircular channel extending along the exterior surface thereof from said trigger mechanism to the end of said elongated body with the axis thereof parallel to the axis of elongation of said elongated member and perpendicular to but spaced from said axis of said tapped passageway.
Claim 11
Dependent Claim
56 words
A collapsible cross-bow as claimed in claim 8 wherein said elongated body is a hollow tubular body closed at said one end by a solid portion and removably sealed water-tight at the other end by a cap to form a sealed container dimensioned to receive said pair of resilient arms, said bowstring and said trigger mechanism.
Claim 12
Dependent Claim
197 words
A cross-bow as claimed in claim 7 comprising a bracket having a pair of spaced upstanding walls a first pin extending transversely between said upstanding walls at one end thereof, a rolling block comprising an axially apertured right circular cylinder mounted on said pin for rotation thereabout said cylinder having a pair of diametrically opposed notches in the exterior surface thereof, a second pin extending transversely between said upstanding walls, and an elongated trigger lever mounted between its ends on said second pin for pivotal movement thereabout, the length of said trigger lever and the spacing between said pins being selected to enable one end of said trigger lever to be pivoted into blocking engagement with one of said notches in the exterior of said cylinder to prevent rotation of said cylinder in one direction and to be pivoted out of said blocking engagement with said one of said notches in the exterior of said cylinder by the application of force to the other end of said lever to permit rotation of said cylinder in said one direction by a bow-string received under tension in the other of said notches in the exterior surface of said cylinder.
