Description

intellectual property office of n.z. 1 5 JUN 2006 received NEW ZEALAND PATENTS ACT, 1953 No: 540820/545321 Date: 17 June 2005 / 14 February 2006 COMPLETE SPECIFICATION VINE SUPPORT SYSTEM We, STEEL & TUBE HOLDINGS LIMITED trading as HURRICANE WIRE PRODUCTS, a New Zealand company of 15-17 Kings Crescent, Lower Hutt, New Zealand, do hereby declare the invention for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: 2 FIELD OF THE INVENTION This invention relates to vineyard trellis systems and, more particularly, to a vine support system for supporting trellis wires from posts. The system of the invention also has application in supporting other types of elongate members from posts.

BACKGROUND OF THE INVENTION Vines such as grapes are typically grown and trained on trellis structures. Posts are driven into the ground in parallel rows and trellis wires are extended along each row, the wires being supported by the posts and anchored under tension.

Metal or plastic posts have advantages in this application as they do not rot or leach 15 preservatives into the soil, as occurs with untreated or treated timber posts respectively. Twisted wire clips may be used to fix the wires to the posts, or brackets may be screwed or bolted to the posts to engage the wires. Unlike the use of a staple to fasten the wire to a wooden post, these systems also allow the wires to be readily dctached and re-fixed at a higher position to accommodate growth of the vine. However the use of twisted 20 wire clips, bolts or screws typically involves more labour or the use of tools to perform this operation. There is therefore a need for a vine support system that is simple and inexpensive to install, preferably without the need for tools.

US 6,209,853 describes an electric wire support bracket for fence posts. This bracket is 25 attached the post by a tie member or clip that extends around the exterior of the post. Such a system could be prone to slippage on the post.

US 6,405,478; US 4,642,940; and US 3,820,758 have fasteners that extend around the exterior of the fence post and could again be prone to slippage on the post.

US 6,434,883 describes a device that extends through slots in a post, and requires a specially-designed post having two spaced-apart flanges to maintain the device in a desired orientation.

In this specification where reference has been made to patent specifications, other external documents, or other sources of information, this is generally for the purpose of 668057-1 3 providing a context for discussing the features of the invention. Unless specifically stated otherwise, reference to such external documents or such sources of information is not to be construed as an admission that such documents or such sources of information, in any jurisdiction, are prior art or form part of the common general knowledge in the 5 art.

It is an object of at least preferred embodiments of the present invention to address at least one of the foregoing problems or at least to provide the public with a useful choice.

I 3 MAR 2007 received 7 BRIEF DESCRIPTION OF DRAWINGS Further aspects of the present invention will become apparent from the following description which is given by way of example only and with reference to the 5 accompanying drawings in which: Figure 1 is an exploded pictorial view of the vine support system of a preferred form of the present invention; Figure 2 is a pictorial view of the vine support system of Figure 1 assembled in use; Figure 3 is a front view of the bracket of the vine support system of Figure 1; Figure 4 is cross-section CC from Figure 3; k Figure 5 is detail A from Figure 4; Figure 6a is a part sectional/plan view of the vine support system of Figure 2; Figure 6b is a cross-section BB from Figure 6a; and 15 Figure 7 is a rear perspective view of the bracket of the vine support system of Figure 1.

DETAILED DESCRIPTION OF PREFERRED FORMS Referring to Figures 1 and 2, a preferred form vine support system includes a bracket 3 for supporting trellis wires 4 and which is adapted to be fixed to a longitudinally extending flange 5 of an upright post 1 by means of a fastener 2 received in an aperture 15.

The bracket 3 has a body 8 defining a slot 6 for receiving the post flange 5. The body I has a rear surface 8c and the slot 6 extends into the body from the rear surface 8c. The body 8 extends laterally outwardly from either side of the slot 6 to define opposing distal ends 8a, 8b of the body. In use, the distal ends of the body extend laterally outward from the post 1. Fastener-receiving means or portions are disposed in the 30 bracket on either side of the slot.

In the form shown (see Figure 3, 6a, and 7), the fastener-receiving means comprise a pair of substantially parallel fastener-receiving apertures or openings 9a, 9b that extend through the bracket body 8 and are positioned outwardly from either side of the slot 6. 35 Each of the distal ends 8a, 8b of the body preferably include first and second wire-receiving means which may be in the form of trellis wire channels 10a, 10b, 11a, 1 lb which are adapted to open upwardly and downwardly in use. While four wire-receiving channels are shown, the bracket may have fewer or more wire-receiving channels. 880458-1 INTELLECTUAL PROPERTY OFFICE OF N.Z. 13 MAR 2007 received 8 The post 1 is Y-shaped in cross-section, including flanges 6 and 7, joined to flange 5. Preferably, the post has a plurality of apertures 15, and may have apertures in one, some, or all of the flanges. The wires 4 supported in upwardly opening apertures 1 Oa, 10b extend horizontally adjacent the edges of the flanges 6, 7.

In the form shown, the fastener 2 has a mid-portion 12 and two end portions 13a, 13b elongated generally parallel to one another and generally perpendicular to the mid-portion, the ends 13a, 13b being adapted to be received in the openings 9a, 9b with the mid-portion 12 extending through the aperture 15 in the post. A generally centrally-10 disposed section of the mid portion extends through the aperture 15 in the post. The portions of the fastener disposed outwardly of the generally centrally-disposed section of the mid-portion, including the ends 13a, 13b, allow a tensile/compressive load to be applied to the mid-portion 12 to strengthen the bracket in bending (under the vertical load of the weight of the trellis wire and supported vines). The end portions of the 15 fastener also strengthen the bracket against horizontal loads from wind and harvesting.

A necked region 24 of each trellis wire channel 10a, 11a that is preferably elastically deformable or resilient serves to retain wire between a closed region of the channcl and the necked region 24. The necked portions 24 in the wire slots 11a, lib may be adapted 20 to receive different gauge wires therethrough, allowing the bracket to be inverted depending upon the wire gauge to be used and provide positive location and a degree of retention in the slot. Alternatively, the wire could be inserted into the bracket from above or below, depending on the gauge of the wire. The wire can be pressed past the necked region of the respective trellis wire channel to position the wire within the 25 channel. The wire receiving channels 10a, 10b, 11a, lib could alternatively be adapted to receive wires of the same gauge. The preferred form bracket could be used to concurrently support four wires.

Referring to Figures 4, 5, and 7, the fastener-receiving portions in the body of the 30 bracket further comprise recesses 18a, 18b extending outwardly in a generally lateral direction from the slot to receive respective sections 12a, 12b of the mid-portion of the fastener. The recesses 18a, 18b terminate in the apertures 19a, 19b. The sections 12a, 12b of the mid-portion for receipt in the recesses 18a, 18b of the bracket comprise means for snap-engaging in the recess to connect the fastener to the bracket. In the 35 form shown, the mid-portion of the fastener 2 comprises two pairs of detents or tabs 17a, 17b each located on sections of the mid-portion for receipt in the recesses. A notch 668057-1 9 or shoulder 19a, 19b is formed in each recess 18a, 18b for abutting each tab 17a, 17b. The tabs 17a, 17b and/or the shoulders 19a, 19b are resilient to enable passage through the recesses 18a, 18b as the fastener 2 is inserted in the recesses in a first direction 20 parallel to the longitudinal axis 21 of the ends 13a, 13b to provide a snap-engagement.

The tabs 17a, 17b impinge on an inner surface of the shoulders 19a, 19b to inhibit unintended removal of the fastener 2 in a second direction opposite to the first direction.

The generally centrally-disposed section 16 of the mid-portion 12 may be offset toward the ends 13a, 13b from the adjacent parts 12a, 12b of the mid-portion, to form a 10 generally E-shaped fastener. In an alternative embodiment, the generally centrally-disposed section may not be offset, so that the fastener has a general C-shape. The generally centrally-disposed section 16 preferably comprises reinforcements 23 which increase the cross-section where the generally centrally-disposed section is received in the aperture 15 in the post 1.

Referring to Figures 6a and 6b, in use, the closed regions of the trellis wire channels 10a, 10b are preferably upwardly convex and 11a, lib are preferably downwardly convex which results in a convex surface 25 for abutting the wire 4. The crests of the surfaces at point 26 lie in an upright plane 27 which is perpendicular to an upright plane 20 28 that bisects the bracket 3 and fastener 2. The crests of the surfaces are preferably co-planar with the generally centrally-disposed section of the fastener. The weight applied to the bracket 3 at point 26 is reacted at point 29, where the planes 27 and 28 intersect, minimising any tendency for the torque applied by the weight of the wires and vines to rotate the bracket in plane 27. The application of the vine loading force at this point 25 also reduces the torque applied to the post in the direction of the bracket mounting flange on the post.

As illustrated in Figure 7, the slot 6 extends generally between opposing faces 30 and 31, each having a raised lip 32 around the edges of the slot 6. The slot 6 is bounded by 30 generally parallel opposing edges 33 of the lips 32 and by edges 34 of two pairs of opposing ribs 35. Ribs 35 help prevent any burrs on the aperture of the post flange from interfering with the bracket slot when the bracket is mounted over the post flange and onto the fastener.

In use the fastener 2 is inserted into a selected aperture 15 in the flange 5. To fix the bracket the two ends 13a, 13b are then pressed into the respective apertures 9a, 9b and 668057-1 pressed home until the tabs 17a, 17b snap behind the shoulders 19a, 19b. A wire 4 may then be entered into one or each of the upwardly opening channel 10a, 10b and/or one or each of the downwardly opening channels and pressed past the necked portions 24.

It will be appreciated that generally, there will be a number of spaced apart posts, each of which has one or more of the support systems mounted thereto to support one or more wires.

The fastener and bracket are preferably made of a suitable material such as plastic, and 10 may be made by a moulding process for example. A preferred material is glass-filled nylon. The post may be made of a suitable material such as steel for example. However, other materials and manufacturing processes may be used as applicable.

At least preferred forms of the present invention provide a support system which is 15 effective and efficient in operational use, which has an overall simple design which minimises manufacturing costs and maximises performance and ease of installation, allowing trellis wires to be readily fastened or unfastened without the need for tools.

The weight of the trellis wire and supported vines may apply a bending load to the 20 bracket in use. It will be understood that the manner of fixing the fastener according to preferred forms of the invention goes at least some way toward counteracting this bending while allowing the bracket to be readily moulded.

The bracket can be removed and fastened to a different aperture of the post flange if 25 necessary.

The above describes preferred forms only, and it should be appreciated that modifications and additions may be made thereto without departing from the scope of the invention.

For example, while the fastener-receiving openings 9a, 9b are shown as being generally parallel, if a fastener with sufficient flexibility or resilience is used, the fastener-receiving openings could be oriented at an angle relative to one another.

Further, while the preferred embodiment has two fastener-receiving openings 9a, 9b for receipt of the end portions of the fastener, an alternative configuration fastener could be 668057-1 11 used that does not have such end portions. For example, the fastener could be provided without the end portions and the bracket provided without the apertures 9a, 9b. The sections 12a, 12b of the mid-portion could still maintain the fastener engaged with the bracket. Alternatively, the fastener-receiving portions may only have the openings 9a, 5 9b, and not the recesses.

Also, in the form shown, the end portions of the fastener are a relatively loose fit in the apertures. Instead, the end portions could be an interference fit or snap fit for example.

While the system is described for supporting vine trellis wires from posts, it could be used for supporting other types of fencing or trellis wires from posts. The system could also be used to support other types of elongate members.

The wire-receiving means 10, 10, 11a, lib are described and shown as being channels. 15 However, the wire-receiving means could instead be apertures. The apertures could be provided with the features described above with reference to the channels; for example the convex wire-abutting faces, tight fit of the wires, etc. It will be appreciated that wire-receiving channels offer the benefit of enabling easy insertion and removal of the wire or elongate member through the necked regions. If the wire-receiving means are 20 apertures, the wires would need to be threaded through the apertures. 668057-1 12
