Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
112 words
A boomerang of generally planar configuration comprising: a body having a central area and a plurality of wings extending outwardly therefrom, and including an internal plastic armature and a soft outer covering, said internal armature being of generally planar configuration and disposed so as to provide support for said soft outer covering, said body further including internal reinforcing pads in the tips of said wings, said pads being of generally planar configuration and positioned such that the planes thereof are parallel to the plane of said body and overlap the tips of said internal armature so as to cushion the impact resulting from a collision between said boomerang and a hard surface.
Claim 2
Dependent Claim
112 words
A boomerang of generally planar configuration comprising: a body having a central area and a plurality of wings extending outwardly therefrom, and including an internal plastic armature and a soft outer covering, said internal armature being of generally planar configuration and disposed so as to provide support for said soft outer covering, said body further including internal reinforcing pads in the tips of said wings, said pads being of generally planar configuration and positioned such that the planes thereof are parallel to the plane of said body and overlap the tips of said internal armature so as to cushion the impact resulting from a collision between said boomerang and a hard surface.
Claim 3
Dependent Claim
35 words
A boomerang as recited in claim 1 wherein said internal armature is described by a planform perimeter following a path which is inside of and generally equidistant from the planform perimeter of the outer covering.
Claim 4
Dependent Claim
35 words
A boomerang as recited in claim 1 wherein said internal armature has at least one perforation, normal to its plane, allowing a direct bond between the upper and lower surfaces of said soft outer covering.
Claim 5
Dependent Claim
18 words
A boomerang as recited in claim 1 wherein said soft outer covering is comprised of a resilient material.
Claim 6
Dependent Claim
13 words
A boomerang as recited in claim 4 wherein said resilient material is cellular.
Claim 7
Dependent Claim
28 words
A boomerang as recited in claim 1 having external flexible boots covering the wingtips in order to protect said wingtips from damage due to impacts with hard surfaces.
Claim 8
Dependent Claim
123 words
A boomerang of generally planar configuration comprising: a body having a central area and a plurality of wings extending outwardly therefrom, and including an internal plastic armature and a soft outer covering, said internal armature being of generally planar configuration and disposed so as to provide support for said soft outer covering, said internal armature having wing segments extending along said wings, with each said segment including a rim having a central portion spaced apart from distal end of the segment and end portions jioning the segment in the vicinity of the outer extremities of the leading and trailing edges thereof, whereby said rim readily deflects and absorbs the impact of a collision between the tip of said boomerang and a hard surface.
Claim 9
Dependent Claim
123 words
A boomerang of generally planar configuration comprising: a body having a central area and a plurality of wings extending outwardly therefrom, and including an internal plastic armature and a soft outer covering, said internal armature being of generally planar configuration and disposed so as to provide support for said soft outer covering, said internal armature having wing segments extending along said wings, with each said segment including a rim having a central portion spaced apart from distal end of the segment and end portions jioning the segment in the vicinity of the outer extremities of the leading and trailing edges thereof, whereby said rim readily deflects and absorbs the impact of a collision between the tip of said boomerang and a hard surface.
