Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 208 words
A trellis wire support system comprising: a plurality of horizontally spaced apart vertical posts adapted to support between them one or more trellis line wires; each post having a first side defined by horizontally spaced apart co-planar contact surfaces defining substantially the maximum width of said first side; said spaced apart posts positioned with their respective first sides disposed substantially parallel to the direction in which the line wires extend; a plurality of substantially identically formed generally Z-shaped bracket arms; at least one bracket arm mounted on each post; each bracket arm comprising a central flat web portion and first and second leg portions extending outwardly in opposite directions from, and at right angles to respectively associated opposite ends of said web portion; each bracket arm mounted on a post with the flat web section of the bracket arm securely positioned in contacting position with the respective first sides of an associated post and with the leg portions extending laterally outwardly to opposite sides of said post in opposite directions perpendicular to the plane of the spaced apart flat surfaces on the first side of said post; and means associated with the outer ends of the leg portions of each bracket arm for supporting a trellis line wire.
Claim 2
Dependent Claim 208 words
A trellis wire support system comprising: a plurality of horizontally spaced apart vertical posts adapted to support between them one or more trellis line wires; each post having a first side defined by horizontally spaced apart co-planar contact surfaces defining substantially the maximum width of said first side; said spaced apart posts positioned with their respective first sides disposed substantially parallel to the direction in which the line wires extend; a plurality of substantially identically formed generally Z-shaped bracket arms; at least one bracket arm mounted on each post; each bracket arm comprising a central flat web portion and first and second leg portions extending outwardly in opposite directions from, and at right angles to respectively associated opposite ends of said web portion; each bracket arm mounted on a post with the flat web section of the bracket arm securely positioned in contacting position with the respective first sides of an associated post and with the leg portions extending laterally outwardly to opposite sides of said post in opposite directions perpendicular to the plane of the spaced apart flat surfaces on the first side of said post; and means associated with the outer ends of the leg portions of each bracket arm for supporting a trellis line wire.
Claim 3
Dependent Claim 44 words
The combination of claim 1 and wherein said last named means comprises a keyhole shaped opening formed through each leg adjacent its outer end, a wire access passageway connecting the outer edge of each leg portion with the interior of said keyhole shaped opening.
Claim 4
Dependent Claim 48 words
The combination of claim 2 and wherein said keyhole opening is defined by an upper arcuate opening located above the horizontal axis of the wire access passageway and a lower arcuate opening in communication with the upper opening located below the horizontal axis of said wire access passageway.
Claim 5
Dependent Claim 21 words
The combination of claim 3 including means for retaining in place a wire inserted through said passageway into said keyhole opening.
Claim 6
Dependent Claim 69 words
The combination of claim 4 and wherein said wire retaining means comprises two closely vertically spaced apart oppositely outwardly bent upper and lower flaps, and wherein the vertical spacing between the flaps defines the wire access passageway, and wherein further said flaps are arranged and constructed to be manually bent and pinched toward one another to narrow and substantially close the passageway to prevent a wire from passing therethrough.
Claim 7
Dependent Claim 68 words
The combination of claim 1 and wherein each post is generally T-shaped in cross section, defining a central stem portion and two laterally spaced apart right and left wing sections co-planar with each other and lying in a plane perpendicular to the vertical plane of the central stem portion; and wherein the said two laterally spaced apart flat surfaces are defined by said left and right wing sections.
Claim 8
Dependent Claim 17 words
The combination of claim 6 and wherein each post is formed as a solid T-bar fence stake.
Claim 9
Dependent Claim 16 words
The combination of claim 6 and wherein each said post is fabricated from roll formed metal.
Claim 10
Dependent Claim 40 words
The combination of claim 1 and wherein each said post comprises a wood stake rectangular in cross section and wherein said two laterally spaced apart flat surfaces comprise the spaced vertical marginal areas of one side of each rectangular post.
Claim 11
Dependent Claim 223 words
A trellis wire support system comprising: a plurality of horizontally spaced apart vertical posts adapted to support between them one or more trellis line wires, each post defining a generally T-shape in cross-section including a central longitudinal stem portion and two laterally spaced apart right and left wing sections co-planar with each other and lying in a plane perpendicular to the vertical plane of the central stem; said spaced apart posts positioned with their left and right wing sections disposed substantially parallel to the direction in which the line wires extend; a plurality of substantially identically formed generally Z-shaped bracket arms; at least one bracket arm mounted on each post; each bracket arm comprising a central flat web portion and first and second leg portions extending outwardly in opposite directions from, and at right angles to, the respectively associated ends of said web portion; each bracket arm mounted on a post with the flat web section of the bracket arm securely positioned in contacting position with the left and right wing sections of an associated post and with the leg portions extending laterally outwardly to opposite sides of said post in opposite directions perpendicular to the plane of the right and left wing sections of said post and means associated with the outer end of each leg portion for supporting a trellis wire.
Claim 12
Dependent Claim 223 words
A trellis wire support system comprising: a plurality of horizontally spaced apart vertical posts adapted to support between them one or more trellis line wires, each post defining a generally T-shape in cross-section including a central longitudinal stem portion and two laterally spaced apart right and left wing sections co-planar with each other and lying in a plane perpendicular to the vertical plane of the central stem; said spaced apart posts positioned with their left and right wing sections disposed substantially parallel to the direction in which the line wires extend; a plurality of substantially identically formed generally Z-shaped bracket arms; at least one bracket arm mounted on each post; each bracket arm comprising a central flat web portion and first and second leg portions extending outwardly in opposite directions from, and at right angles to, the respectively associated ends of said web portion; each bracket arm mounted on a post with the flat web section of the bracket arm securely positioned in contacting position with the left and right wing sections of an associated post and with the leg portions extending laterally outwardly to opposite sides of said post in opposite directions perpendicular to the plane of the right and left wing sections of said post and means associated with the outer end of each leg portion for supporting a trellis wire.
