APPARATUS FOR FASTENING OF RASPBERRY STEMS IN VERTICAL AND HORIZONTAL POSITION Russian patent published in 2006 - IPC A01G1/00 

FIELD: agriculture, in particular, horticulture, more particular, growing of raspberry plant fastened with its stems to trellis.

SUBSTANCE: apparatus has trellis made in the form of rods with tightened wire and fastening members. Trellis is made doubled, in the form of two parallel trellises spaced apart from one another by distance of about 0.5 m. Paired outer rigid rods and intermediate rods along row of trellises are spaced by distance of 2.5 m from one another and connected by their top end parts with one another through quick detachable tie-rods. Intermediate rods are made from wires with rings equally spaced from one another in vertical plane. In lower end parts of rods said rings are fixed at height of about 0.25 m and 0.5 m and are positioned in transverse plane relative to upper rings. Member for fastening of plant stem in vertical position to tightened wire is made in the form of U-shaped wire clip with radial part at apex contacting with plant stem. Wire clip has U-shaped end parts cooperating with tightened wire and extending in plane transverse to clip plane. One of end parts of clip is pressed to straight portion of U-shaped clip to define closed contour allowing rotation thereof around tightened wire. Gap between other U-shaped end part of U-shaped clip and tightened wire, with closed part of clip being disposed on wire, is about 20 mm to provide for unobstructed passage of plant stem which is positioned within triangle of U-shaped clip joined to tightened wire in spaced relation and between sides of said triangle. For fastening of plant stems in horizontal position, apparatus has arcuate wire length positioned at plant base, said wire length being radially bent at one side for distance of 0.25 m and has protrusions made concave at both sides in direction transverse to arcuate portion and adapted for contacting with stem, and made straight at its other side. Small wire arcuate portion is pivotally mounted in upper part of main arcuate wire length for contacting plant stem. Rod has Z-shaped end portion adapted for contacting ground surface.

EFFECT: improved agronomical and operating characteristics owing to useful employment of two-row trellis, quick mounting an dismantling of plant stems to trellis and therefrom, and convenient caring of stems fixed both in vertical and horizontal positions.
