摘要:
The tensioned wires (33, 34) serving for tying on the vines are supported by the vineyard stakes (11) which are driven into the earth. The stake is a rolled cross-sectionally approximately oval hollow profile (42) made of steel, one less bent side (14) of which is open. The stake (11) is provided on both its more bent sides (12, 13) with punchings (24, 26, 36), by which the attachment devices (24, 26, 36; 29, 31) for the wires (33, 34) are formed. The other, less bent side (14) is provided with a number of cross-sectionally C-shaped longitudinal corrugations (46', 47') which are directed inwards and outwards alternately. The more bent sides (12, 13) end in longitudinal channels (48, 49), the end faces (51, 52) of which face the interior of the hollow profile (42). The more bent sides (12, 13) have cross-sectionally V-shaped longitudinal corrugations (46, 47). The walls (43, 44) having punchings (24, 26, 36) enclose an angle of 30 DEG . The cross-sectional surfaces of the longitudinal channels (48, 49) can extend over an angle of 270 DEG . The vineyard stake can be driven in with less force than and does not have to be driven in as deeply as other vineyard stakes. Retightening of the wires is simple because these do not jam in the vineyard stake. <IMAGE>
