Abstract
In a vineyard or the like, a system for positioning and tensioning the wires which form the trellis disposed between and among an array of metal posts upon which vines are trained, including retainers for selectively positioning wires relative to the metal posts and each other and further including a subsystem for applying the appropriate tension to the various wires making up the trellis.
Claims11
In a system for positioning and tensioning wires, said wires intersecting to form a trellis mounted to an array of metal posts, each said metal post including a cross arm affixed thereto, said cross arm having several apertures formed therein, said apertures being substantially equally spaced, and aligned in a row along the longitudinal axis thereof;
- at least one tensioning subsystem for applying a predetermined tension on each said wire;
- a retainer, said retainer securing one of said wires relative to said cross arm, said retainer having a center portion, the length of which is substantially equal to the distance between adjacent apertures, opposed legs being formed integrally with said center portion, one of said legs terminating in a hook, said hook being open to receive a said wire, with said legs projecting through adjacent said apertures and being snapped into position on said cross arm.
In a system for positioning and tensioning wires, which wires intersect to form a trellis mounted on an array of metal posts, each said metal post including a cross arm affixed thereto, wherein the trellis and posts together define a matrix for the growing of vine fruit, means for securing said wires relative to said metal posts comprising:
- a plurality of retainers, including a retainer for securing at least one wire relative to a metal post, said retainer comprising an elongate, relatively resilient length of wire, said wire being so formed as to attach to a portion of a said metal post, said retainer having at least one loop formed at an end thereof, said loop being open so as to receive a wire of said trellis and secure the same relative to the said metal post in a predetermined position;
- at least one tensioning subsystem for applying a predetermined tension on each said wire;
- a second retainer for securing at least one said wire relative to a metal post, said retainer comprising an elongate, relative resilient length of a said wire, said wire being so formed as to attach to a portion of said metal post, said retainer having at least one loop formed at an end thereof, said loop being open so as to receive a said wire of said trellis and secure the same relative to the said metal post in a predetermined position;
- each said metal post being formed with a series of coplaner apertures aligned in a row and wherein said retainer is adapted to be fitted into at least two of said apertures to secure the same to the said metal post;
- at least a third retainer for securing at least one wire relative to another, said retainer comprising an elongate, relatively resilient length of a said wire, said retainer having at least one loop formed at an end thereof, said loop being open so as to receive a said wire of said trellis;
- an elbow formed in said length of a said wire, said elbow adapted to circumscribe an intersecting wire of the trellis to thereby secure said wires relative to one another.
