Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
163 words
An antenna system comprising a plurality of telescoping tubes retractable one within the other with all of said tubes being retractable within the tube having the largest diameter; a first hinge member connected to One of two adjacent tubes; and a second hinge member connected to the other of said adjacent tubes; said hinge members being pivotally connected to permit relative pivotal movement between said adjacent tubes; said first hinge member being formed with a bore and including a cylindrical slug disposed in said bore, said slug having a flat surface, and resilient means urging said slug outwardly towards said first hinge member; said second hinge member having at least two flat portions formed thereon, said flat portions adapted to engage said flat surface of said slug to hold the inner of said two adjacent tubes in at least two positions relative to the outer of said two adjacent tubes, said hinge members and said inner tube being retractable into said outer tube.
Claim 2
Dependent Claim
163 words
An antenna system comprising a plurality of telescoping tubes retractable one within the other with all of said tubes being retractable within the tube having the largest diameter; a first hinge member connected to One of two adjacent tubes; and a second hinge member connected to the other of said adjacent tubes; said hinge members being pivotally connected to permit relative pivotal movement between said adjacent tubes; said first hinge member being formed with a bore and including a cylindrical slug disposed in said bore, said slug having a flat surface, and resilient means urging said slug outwardly towards said first hinge member; said second hinge member having at least two flat portions formed thereon, said flat portions adapted to engage said flat surface of said slug to hold the inner of said two adjacent tubes in at least two positions relative to the outer of said two adjacent tubes, said hinge members and said inner tube being retractable into said outer tube.
Claim 3
Dependent Claim
31 words
The system of claim 1 wherein said inner tube is held in a position coaxially aligned with said outer tube and in a position angularly disposed relative to said outer tube.
Claim 4
Dependent Claim
54 words
The system of claim 2 wherein said first hinge member has a pair of arms on either side of said bore projecting toward said second hinge member, and said second hinge member has a projecting portion projecting between and pivotally connected to said arms, said two flat portions being formed on said projecting portion.
Claim 5
Dependent Claim
23 words
The system of claim 1 further comprising means to mount said outer tube in a generally perpendicular direction with respect to a housing.
Claim 6
Dependent Claim
52 words
The system of claim 1 wherein said tubes include at least one additional tube connected to and retractable within said inner tube to enable the length of the tubes beyond said hinge members to be adjusted when said inner tube is coaxially aligned with and angularly disposed relative to said outer tube.
