Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 295 words
A road reflector device comprising, in combination: a base member; bearing means on said base member; two pivotable supporting arms held in said bearing means; said pivotable supporting arms being comprised of bent wire; spring means connected to said supporting arms for urging said arms toward an upper surface of said base member; said two arms being urged by said springs to pivot in opposite rotational directions; a vertical member held in standing position on said base member when abutted by said two arms on opposite sides of said vertical member; and light reflector means carried by said vertical member; said base member being a single one-piece plate-shaped member; said vertical member being detached from said base member and standing freely on said base member when in a vertical position, said vertical member standing on said base member free from being structurally connected to said base member, said arms abutting said vertical member at a substantial distance from said base member, said vertical member being freely removable from between said arms without disconnecting said vertical member from said base member, said arms being urged to pivot and contact the upper surface of said base member by said spring means after removal of said vertical member from between said arms, each arm being pivotally held in said bearing means at a substantial distance along the base member from the position of contact of said vertical member with said base member so that said arm forms substantially the hypotenuse of a right triangle having one arm along the base member and one arm along said vertical member; said arms being pivoted to lie against said base member when said vertical member is removed from between said arms; the triangular structure forming supporting means for said vertical member.
Claim 2
Dependent Claim 295 words
A road reflector device comprising, in combination: a base member; bearing means on said base member; two pivotable supporting arms held in said bearing means; said pivotable supporting arms being comprised of bent wire; spring means connected to said supporting arms for urging said arms toward an upper surface of said base member; said two arms being urged by said springs to pivot in opposite rotational directions; a vertical member held in standing position on said base member when abutted by said two arms on opposite sides of said vertical member; and light reflector means carried by said vertical member; said base member being a single one-piece plate-shaped member; said vertical member being detached from said base member and standing freely on said base member when in a vertical position, said vertical member standing on said base member free from being structurally connected to said base member, said arms abutting said vertical member at a substantial distance from said base member, said vertical member being freely removable from between said arms without disconnecting said vertical member from said base member, said arms being urged to pivot and contact the upper surface of said base member by said spring means after removal of said vertical member from between said arms, each arm being pivotally held in said bearing means at a substantial distance along the base member from the position of contact of said vertical member with said base member so that said arm forms substantially the hypotenuse of a right triangle having one arm along the base member and one arm along said vertical member; said arms being pivoted to lie against said base member when said vertical member is removed from between said arms; the triangular structure forming supporting means for said vertical member.
Claim 3
Dependent Claim 18 words
A road reflector device as defined in claim 1, wherein said vertical member is a substantially plate-shaped member.
Claim 4
Dependent Claim 21 words
A road reflector device as defined in claim 1, wherein said supporting arms comprised of bent wire have a rectangular shape.
Claim 5
Dependent Claim 27 words
The road reflector device as defined in claim 3, wherein said spring means comprises coiled springs wound on at least one side of said rectangular-shaped wire arm.
Claim 6
Dependent Claim 30 words
The road reflector device as defined in claim 4, wherein said arms form acute angles with the horizontal when holding said vertical member in standing position on said base member.
Claim 7
Dependent Claim 28 words
The road reflector device as defined in claim 4, wherein said coiled springs have one end connected to said base member and another end connected to said arm.
Claim 8
Dependent Claim 29 words
The road reflector device as defined in claim 4, wherein said springs have identical spring characteristics for holding said vertical member in a central position on said base member.
Claim 9
Dependent Claim 17 words
The road reflector device as defined in claim 1, wherein said base member is a plate-shaped member.
Claim 10
Dependent Claim 24 words
The road reflector device as defined in claim 1, wherein said light reflector means comprises a plurality of reflectors supported by said vertical member.
Claim 11
Dependent Claim 141 words
A road reflector as defined in claim 1 wherein said vertical member is a substantially plate-shaped member, said supporting arms comprising bent wire having a rectangular shape, said spring means comprising coiled springs wound on at least one side of said rectangular-shaped wire arm, said arms forming acute angles with the horizontal when holding said vertical member in standing position on said base member, said coiled springs having one end connected to said base member and another end connected to said arm, said springs having identical spring characteristics for holding said vertical member in a central position on said base member, said base member being a plate-shaped member, said light reflector means comprising a plurality of reflectors supported by said vertical member, said vertical member comprising a panel-shaped member, said vertical member being of plexiglass, said base member being of aluminum.
