Referring now to Figure 2c, where there is illustrated a clip 37 similar to the one in Figure 2b. The clip 37 has a cross-sectional shape that is continuous, and substantially circular. This clip 37 is sized and adapted to so as to nest inside of a conduit 40 such that the outer surface of the conduit 40 securely nests against the inner wall of the clip 37,so as to capture sheet 22 and sheet 23 to allow joining of two sheets. Edges 17 and 19 of the clip can be of any varying shape and the gap 41 can be of any size according to job application
Referring now to Figure 2d where the clip 37 has the sheets of material 22 ■ S- overlapping within the clip 37 but as shown are still secured against the length of conduit 40. The clip 37 is essentially being used as a joiner.
As an adjunct to this wire 55 can be placed between material 22 and material 23 and a electric charge passed through the wire so as melt HDPE material • with the sheeting together. Edges 17 and 17 of the clip 37 can be of any varying 10 shape and the gap 41 can be of any size according to job application
Referring now to Figure 3a, where an exemplary application for the clip 4 described in figures 1 and 2a is illustrated. Here the clips are shown securing a sheet of plastic material 20 to the fengths of conduit 14, and the piastic 20 is being used to protect a grape vine 50 in this case, from birds, sun damage 15 and/or frost damage.
The clips have been used to retain the plastic sheet 20 to lengths of conduit 14 on either side of the vine. The lengths of conduit 14 in turn have been secured to lengths oi steel wire 30 running between upright posts 38 by wire catches 32. These wire catches 32 include a cupped portion 34 adapted to nest and engage 20 the conduit 14, and an elongate tail portion 36 that extends downwardly, and which can then be looped around the length of wire .30 so as to secure the conduit 14 and sheet 20 in turn to the wire 30.
There may be a further conduit 14 secured to a wire 30 suspended above the vine 50, this conduit being secured to the wire in the same fashion as above.
25 The plastic sheeting 20 may then be extended between the three conduits 14, providing an economical means of protecting the vines. In a further aspect, the lengths of wire and the wooden posts may be replaced by a series of fiberglass or plastic rods that are bent into an arch shape, with each end inserted into the ground. Further still, they may be replaced with a series of star posts that are driven, into the ground such that the conduit can then be placed over the star post and bent into an arch shape.
Referring now to Figures 4 and 5, where a further exemplary aspect of the clip is illustrated. Just as before, this clip 100 is adapted to secure a sheet 130 of material to length of a HDPE conduit 114 of the type that is commonly used for irrigation purposes. The HDPE conduit 114 has been extruded with a ' continuous slot 116 in it, so as to define a pair of oppositely positioned edges 1 16a and 1 16b.
The cliplOO has a cross-sectional shape including a v shaped body with two legs 102 and 104 joined at a common vertex at the legs respective first ends, each leg having a grooved portion 106 in the outer side of the leg, proximate to the second end of the leg. The sheet of plastic 130 is placed over the slot in the conduit, and the body of the clip is then passed through the slot 116 in the conduit by simultaneously forcing the legs 102 and 104 of the clip 100 together, and expanding the slot 116 in the conduit 114. This insertion operation pulls the sheet materials 30 into the conduit 114 with it until the v~shaped body of the clip has been accepted within the conduit, and the grooved ends 106 on the legs of the clip have captured and retained the open ends 116a and b of the conduit on either side of the slot 116 in the conduit Once insertion has been completed, •■ the clip will have secured the sheeting between its grooved portions 106 and the edges 1 16a and 1 16b of the slot 116.
It -is considered that the clip and retention system according to the present invention would be of considerable use to those in the horticultural and building industries, where it is desirable to cover a large area with a sheet material quickly and relatively cheaply. More specifically, it is considered that it will be of particular use in vineyards, where it is desirable to cover and uncover the vines ii as necessary, quickly and cheaply, or indeed in the construction of pergolas, shade sails or even pool or dam covers.
Throughout this specification the purpose has been to illustrate the invention and not to limit this.
