  • Patent number: 7249439
    Abstract: A trellis wire support apparatus and a trellis system and method for use in vineyards and the like. The trellis wire support comprises a body having at least one a fold configured to releasibly engage a corresponding slot in a support element, and at least one clip or hook configured to releasibly engage a trellis wire. The trellis systems comprise at least one support element having a slot therein, and at least one trellis wire support comprising at least one clip configured to releasibly engage a trellis wire and a fold configured to releasibly engage the slot in the support element. The trellis system may additionally comprise a cross arm, with the support element configured to couple to the cross arm. The cross arm may include parallel ridges extending along its length, and the support element may have notches adjacent each end thereof that are configured to engage the ridges on the cross arm.

  • Patent number: 6138407
    Abstract: A cross arm apparatus for providing structural support in agricultural and other applications. The cross arm comprises a folded section adjacent one edge, a bent, angled or beveled section adjacent a another edge, and a generally planar section or region extending between the folded section and angled section. Slotted catch holes in the ends of the cross arm provide for releasibly attaching wires to the cross arm. Notches and holes in the cross arm allow the cross arm to be attached to other structural elements such a vertical supports or additional cross arms. The cross arm can be assembled with a vertical support and additional cross arms to provide a variety of trellis structures.
