Definitions

  • This invention relates to a polytunnel arrangement for use in the cultivation of crops, providing protection for the crops and/or enabling the growing environment to improved or optimised to increase production.
  • One form of polytunnel arrangement in common use comprises a pair of rows of legs, each of which is secured in position on a ground surface.
  • a series of cover support hoop members are provided, each hoop member being supported at one end by being fixed to or carried by one of the legs of one of the rows, the other end of the hoop member being fixed to or carried by a respective one of the legs of the other of the rows.
  • a cover for example of a flexible plastics material, is supported by the hoop members and is anchored in position using ropes or straps that are secured to fastening points provided on the legs and extend over the cover.
  • the legs of certain of the rows may carry the ends of the hoop members of two adjacent ones of the polytunnel arrangements, thereby reducing the number of component parts required, and allowing the polytunnel arrangements to be provided closer to one another.
  • the upper ends of the legs are typically of bifurcated, generally, U-shaped form, one of the limbs of which is used to support the hoop member associated with one of the polytunnel arrangements, and the other of which is used to carry the associated hoop member of the other of the polytunnel arrangements.
  • the U-shaped parts of the legs may further carry a gutter member arranged to catch and carry rainwater draining from the covers of the polytunnel arrangements to an end thereof.
  • the fastening points to which the ropes or straps used to anchor the cover in position are attached, in use, are typically welded or otherwise secured to the legs at a position beneath the level of the U-shaped parts of the legs, and are only used when no gutter is provided.
  • legs that are of relatively short length, with the result that the ends of the hoop members are supported at relatively low positions, and any gutter provided between adjacent polytunnel arrangements is at a low level.
  • a polytunnel arrangement comprising a pair of rows of legs, each leg having, at its upper end, a generally U-shaped part arranged to carry ends of a pair of hoop members, in use, the generally U-shaped part having a rope anchor bracket secured thereto.
  • the rope anchor bracket conveniently extends in a plane perpendicular to a plane in which the limbs of the generally U-shaped part are located.
  • the rope anchor bracket conveniently curves downwardly from a point at which it is secured to the generally U-shaped part. It is preferably attached, for example, by welding to an upper face of a base part of the generally U-shaped part.
  • the invention also relates, in a second aspect thereof, to a polytunnel arrangement comprising a pair of rows of legs, each leg having, at its upper end, a generally U-shaped part arranged to carry ends of a pair of hoop members, in use, a gutter member supported by the generally U- shaped part, and an auxiliary rope anchor bracket located within a channel defined by the gutter member and secured to the generally U-shaped part.
  • the gutter member may be of a flexible plastics material. Alternatively, it could be of a suitable metallic material.
  • a rope anchor bracket as defined hereinbefore may also be provided.
  • Such an arrangement is advantageous in that it permits anchoring of the cover of a polytunnel arrangement in position whilst also permitting the provision of a gutter. Furthermore, the gutter can, if desired, be at a relatively low level.
  • Figure 1 is a diagrammatic representation of a polytunnel arrangement
  • Figure 2 illustrates a leg used in a typical polytunnel arrangement
  • Figure 3 illustrates a leg used in a polytunnel arrangement in accordance with an embodiment of the invention
  • Figure 4 is a view illustrating the leg of Figure 3 modified in accordance with the second aspect of the invention.
  • a polytunnel arrangement is illustrated, diagrammatically, which comprises first and second rows of legs 10, 12.
  • Each leg 10, 12 includes, at its upper end, a generally U-shaped part 14, the limbs 14a, 14b of which each carry, in use, an end part of a hoop member 16.
  • each hoop member 16 is support, at one end, by a leg 10 in one of the rows, and at its opposite end, by a leg 12 of the other of the rows.
  • a flexible plastics material cover 18 is carried by the hoop members 16, supported in such a manner as to define a barrel shaped roof profile, the cover 18 being anchored in position by anchor ropes or straps 20.
  • each leg may carry the adjacent ends of two hoop members associated with a pair of adjacent polytunnel arrangements.
  • FIG. 2 illustrates a typical design of the leg 10, from which it is clear that, beneath the generally U-shaped part 14, rope anchor hooks 22 are welded to the leg 10.
  • the rope anchor hooks 22 lie in the same plane as the limbs 14a, 14b.
  • the use of a leg of the type shown in Figure 2 allows the construction of a polytunnel arrangement of desired characteristics, it has been found that where the leg is of relatively short length, used in the provision of a polytunnel arrangement of the type in which the ends of the hoop members are supported above the ground surface by only a short distance, the location of the rope anchor hooks 22 beneath the generally U-shaped part impede the operation of attaching the ropes or straps 20 in position, resulting in the assembly or construction of the polytunnel arrangement being of greater complexity and being more time consuming.
  • the rope anchor brackets or hooks 22 are secured, for example by being welded, to an upper surface of the base 14c of the generally U-shaped part 14 of each leg, the rope anchor hooks 22 extending in a plane substantially perpendicular to a plane containing the limbs 14a, 14b of the generally U-shaped part 14.
  • the rope anchor hooks 22 depend downwardly from their points of attachment to the generally U-shaped parts 14.
  • ropes or straps 20 may be laced between the rope anchor hooks 22 to secure or anchor the cover 18 in position.
  • an auxiliary rope anchor bracket or hook 26 is provided, the auxiliary rope anchor hook 26 being located within the channel defined by the gutter material 24 and being secured to the limbs 14a, 14b of the generally U-shaped part 14 by mounting brackets 28 which are clamped or otherwise affixed to the limbs 14a, 14b, and which include parts that extend through openings formed in the gutter material 24 to engage the auxiliary rope anchor hook 26 and fix the hook 26 in position.
  • the auxiliary rope anchor hook 26 conveniently includes two hook parts 26a, 26b thereby allowing a single hook 26 to be used in the attachment of ropes or straps 20 associated with a pair of adjacent tunnel arrangements, the hook 26 being secured, by a pair of mounting brackets 28 to both limbs 14a, 14b of the generally U-shaped part 14.
  • the invention is advantageous in that it enables the provision of a relatively low level polytunnel arrangement, allowing the attachment of ropes or straps to anchor the cover thereof in a relatively simple and convenient manner. Furthermore, it allows such a structure to be provided with a gutter, at a relatively low level, if desired. Whilst a specific embodiment of the invention is described herein, it will be appreciated that a wide range of modifications and alterations may be made to the arrangement described hereinbefore without departing from the scope of the invention as defined by the appended claims.
