Abstract

The shelter comprises at least one stake (1), having at least one longitudinally extending slot (2), and an enclosure which comprises at least one section (3) of material, the arrangement being such that said section or sections is or are attached to and removed from the stake or stakes by sliding an edge (4) or fold (5) of the or each section into a said slot. The or each section preferably comprise a flat sheet of relatively flexible material which, in use, is bent at least partially around the plant. Thus, one stake, and one section which encircles the plant, may be provided, or a number of stakes and sections may be provided which are arranged around the plant. Alternatively, the enclosure may be of tubular form and attached via a longitudinal fold in the material. As a further alternative, the section may be of rigid sheet, e.g. of faced corrugated plastics, which is sharply bent along appropriate corrugations to surround the plant. <IMAGE>

Description

SPECIFICATION Improvements Relating to Plant Shelters The invention relates to shelters for plants.
Plant shelters are well known devices manufactured from transparent or translucent plastics material and form a total or partial enclosure around plants in order to promote plant growth and provide protection. In one well known form, the plant shelter comprises a tube which is vertically arranged around an individual tree ("Tuley Tube") or vine and attached to a stake driven into the aground.
The attachment arrangements known to date for the enclosures of such plant shelters are based on relatively time consuming methods and/or the use of special tools. This is particularly true when the enclosure is to be transported as a flat sheet for onsite assembly and when the use of metal parts (wire, staples) is inadvisable. Additional problems with existing methods of attachment are the difficulty in dismantling the enclosure, in extending the enclosure at a later date, and in adjusting the position of the enclosure.
An object of the present invention is to provide a plant shelter which can be easily and quickly attached to and removed from one or more stakes, and which is suitable for any type of plant, any shape of enclosure, any number of stakes and any number of plants.
According to the present invention there is provided a plant shelter comprising one or more stakes, each having one or more longitudinally extending slots, and an enclosure which comprises one or more sections of material, preferably transparent or translucent plastics material, the arrangement being such that said section or sections is or are attached to and removed from one or more stakes by sliding an edge or fold of the or each section into a said slot.
The section or sections may comprise flat sheets of relatively flexible material which can be circled wholly or partially around the plant and attached by sliding an edge or edges of the sheet onto a stake via its slot.
Thus, where the enclosure comprises one section, this may be a substantially rectangular flat sheet which is sufficiently flexible to be circled around the plant or plants and attached to a single stake by sliding opposed edges into a slot of a single stake.
Alternatively, the flat sheet can be more rigid, eg of faced corrugated plastics, in which case the sheet is used with the corrugations running vertically and is sharply bent along appropriate corrugations to provide an enclosure which is of polygonal crosssection, eg triangular or rectangular.
Preferably, each stake is tubular with its slot(s) opening into the tube bore, and edges of the sheets which are to be attached to a stake are thickened, eg by doubling over the edge like a hem, so that they can be positively retained behind the slot.
Each stake may be manufactured from a hollow tube of constant internal and external diameter with the slot formed by cutting through the wall over the length of the tube, or as a solid extrusion with one or more preformed slots and, if desired, internal or external reinforcement arrangements. The external reinforcement arrangements may take the form of an uneven surface to improve the stability of the stake in the ground.
In another form, each stake may comprise an elongated plastics member which defines said slot and which is adapted to be fixed along its length to an already existing stake, eg of wood or metal.
In another form, each stake may be manufactured by rolling or bending a flat metal sheet (eg steel) into a tube, the longitudinal edges of which are spaced apart to define a slot.
To facilitate location of the enclosure material into a slot, preferably the intended upper end of the slot widens out.
To facilitate penetration into the ground, each stake has its base end in the form of a spike, or the like.
The enclosure may also assume the cross section of a droplet of water.
Specific embodiments of the invention will now be described, by way of example, with reference to the accompanying drawings in which: Figure 1 shows in perspective a first embodiment of the invention, Figure 2 shows in perspective a second embodiment of the invention, Figure 3 shows in perspective a third embodiment of the invention, Figure 4 shows in perspective a fourth embodiment of the invention, and Figure 5 shows in enlarged cut-away perspective of a fifth embodiment of the invention.
Referring to Figure 1 in the first embodiment, a single stake is used comprising a plastics tube 1 with a full length longitudinal slot 2 opening into the bore of the tube. The tube is arranged externally of the enclosure and holds opposed edges 4 of a single sheet 3 of the enclosure material, which edges are secured to the stake by sliding in the direction shown by the arrow. The edges 4 are doubled over to thicken them so that they will positively engage behind the slot 2. In this embodiment, the enclosure material is sufficiently thick to provide some stiffness to its flexibility, so that it is self-supporting around the plant with the aid of the stake. It will be appreciated that the stake could also be arranged internally of the enclosure.
Referring to Figure 2, in the second embodiment, several tubular stakes 1 are used, each with full length longitudinal slots 2, holding in position separate sheets of enclosure material 3, adjacent sheets being held in position by adjacent thickened, raised edges 4 engaged behind the slot(s) of one stake. As shown, four stakes are provided, which would be circled around a plant or plants. It will be appreciated that, because of the greater support provided by the number of stakes, the enclosure material need not be so stiff as in the first embodiment.
Referring to Figure 3, in the third embodiment, a single stake 1 is used with a preformed enclosure 3 which is tubular in cross section and has a web providing an edge 4, the latter being secured to the stake by sliding it in the direction shown by the arrow into and behind the slot 2.
Referring to Figure 4, in the fourth embodiment, a single stake 1 is again used with a preformed tubular enclosure 3. The tube 3 is secured to the stake by sliding a longitudinally extending fold 5 of the material in the direction shown by the arrow into and behind the slot 2.
It will be appreciated that, where the enclosure is preformed as a tube, it can be made of relatively flexible material, in which case it may need to be supported by sliding a number of folds of material onto stakes arranged around the plant or plants. If the enclosure is made relatively stiff, only one stake may be needed. It will also be appreciated that the preformed tube could be of circular, oval, rectangular, or any other suitable cross-section.
Referring to Figure 5, in the fifth embodiment, a stake is used comprising a plastics tube 1 with a full length longitudinal slot2 opening into the bore of the tube. The tube 1 is held against a conventional stake 6 of wood or any other suitable rigid material by means of strap(s) or clip(s) 7. In this embodiment the enclosure material is made from flat faced corrugated plastics material 9, ie a corrugated inner layer which is faced on each side with a sheet, which, due to the rigidity provided by the corrugations, is used with the corrugations extending vertically, and is shaped by sharply bending it along appropriate corrugations, to provide an enclosure which is polygonal in cross section, eg trianguiar as shown.Along the parts 8 of the enclosure 3 to be retained in the slot 2, the enclosure is suitably modified by reducing the thickness of the material, to provide longitudinal slots close to the two vertical edges of the enclosure to which the edges of the slot 2 of the tube 1 can positively locate.
It will be appreciated that the enclosure could be of any flat sided shape, also that this enclosure could be installed in conjunction with any of the other designs of stake. It will also be appreciated that tube 1 need not extend to the full length of the enclosure 3, nor need it extend to the full length of the conventional stake 6.
Modifications are possible within the scope of the invention. For example, the slot could be shaped with side walls which are adapted to bear against the part or parts of the enclosure member fixed into said slot, thereby providing further rigidity for the enclosure member. It will be appreciated that in this case the enclosure member would be manufactured as a special extrusion, in which case it may be formed with two separate slots in order to separately hold the two edges of an enclosure.
Also, if the stake is installed such that it is shorter than the enclosure, the top of the enclosure may be held closed by means of a clip or a short section of stake cut for the purpose.
In another modification, the stake could be required onlyto close the shelter around the plant, in which case it may not need to be driven into the ground. It will be appreciated that, in this case, support for the shelter would be provided by the plant itself or some other means.
