This invention relates to irrigation system ground spikes for securing components in an irrigation system. Typically, ground spikes of the current type will be used in domestic garden irrigation systems, which are sometimes termed micro irrigation systems.
Such systems can be useful for the consumer in providing a permanent or semi-permanent watering arrangement for use in gardens, allotments, and so on. However existing micro irrigation systems are generally difficult to set up, install and change. Typically a large number of different products/components are required in order to set up even a relatively simple micro irrigation system and time consuming and fiddly operations are required by a user in installing such a system.
It would be desirable to provide an irrigation system or parts for use in an irrigation system, which can provide easy and safe setup as well an effective resulting system.
According to one aspect of the invention there is provided an irrigation system ground spike for securing at least one component of an irrigation system, the ground spike comprising a spike portion for penetrating soil to hold the ground spike in position and at least two holding portions, each holding portion for holding a respective component of an irrigation system, wherein a first of the two holding portions differs from a second of the two holding portions so facilitating use of the spike for selectively securing respective different components.
Thus the ground spike may be multi-functional which can enhance ease of use for the user in setting up an irrigation system and reduce the number of components that need to be manufactured.
One of the holding portions may be arranged for holding tube or hose of a first diameter and another of the holding portions may be arranged for holding tube or hose of a second diameter.
One of the holding portions may comprise a micro tube grip.
One of the holding portions may comprise a supply hose securing lug.
One of the holding portions may comprise an irrigation connector attachment portion for attaching an irrigation connector to the ground spike. The irrigation connector will typically be arranged to allow connection of micro tube and/or other irrigation outlet components such as sprinkler units or dripper units to a supply hose.
One of the holding portions may comprise an irrigation outlet component mounting portion for mounting an irrigation outlet component on the ground spike. The irrigation outlet component may, for example, comprise a sprinkler unit or a dripper unit.
The ground spike may comprise any one of, or any combination of: a micro tube grip, a supply hose securing lug, an irrigation connector attachment portion for attaching an irrigation connector to the ground spike, an irrigation outlet component mounting portion for mounting an irrigation outlet component on the ground spike.
The ground spike may comprise a main body portion from which the spike portion projects. The main body portion and spike portion may be of a single piece of material.
The ground spike may be of a single piece of material.
One of the holding portions may comprise a part circular cut out in the main body portion, which cut out is for holding a micro tube. As such the cut out can be considered a mirco tube grip.
One of the holding portions may comprise a supply hose securing lug which projects from the main body portion.
Where the ground spike comprises said part circular cut out and said hose securing lug, the part circular cut out may define a tube receiving region having a mouth through which tube may be introduced whilst the securing lug and main body may define a hose receiving region having a mouth through which hose may be introduced, wherein the mouth of the tube receiving region is smaller than the mouth of the hose receiving region.
The ground spike may comprise a pair of opposing arms extending from the main body portion. The irrigation connector attachment portion and/or the irrigation outlet component mounting portion may comprise the opposing arms. The arms may define a slot for receiving an attachment portion of an irrigation connector. The arms may define a receiving location for accepting an irrigation outlet component.
The arms may be generally L-shaped in cross section.
The arms may define a first slot between the pair of arms on the one hand and the main body portion in the other hand. The arms may define a second slot transverse to the first slot and between the arms themselves. The second slot may be a keyhole shaped slot. In such a case, a larger dimensioned portion of the keyhole shaped slot may provide the receiving location. An irrigation outlet component may be slid into engagement with the arms. The arms may be resilient.
A groove may be provided in the main body portion to act as a guide for micro tube.
Grips may be provided on the main body portion to assist a user in removing the ground spike from the ground.
There may be a pair of hose retaining lugs, each may project from a respective side of the main body portion. Said respective sides may be opposite sides. The lugs may also be useful in removing the ground spike from the ground.
The spike portion may comprise at least one strengthening longitudinal rib.
According to another aspect of the invention there is provided an irrigation connector arrangement comprising ground spike, as defined above, and an irrigation connector attached to the ground spike.
The irrigation connector may be arranged for tapping into a water supply hose and may comprise a retaining portion for holding a supply hose in a hose receiving region of the retaining portion and a hollow needle extending into the hose receiving region of the retaining portion for penetrating a supply hose held in the retaining portion to create a fluid communication path between an interior of the needle and an interior of a supply hose held in the retaining portion.
The needle may be mounted for movement relative to the retaining portion between a retracted position and an extended position in which the needle extends into the hose receiving region.
The connector may comprise a needle drive arrangement for driving the needle towards the extended position.
The connector may further comprise a water outlet portion for accepting water from the interior of the needle and passing water out of the connector. The water outlet portion may comprise a sealing clamp arrangement for connecting an outlet component to the irrigation connector.
The irrigation connector and spike may comprise complementary attachment portions allowing the connector to be mounted on the spike and the orientation of the connector to be varied relative to the spike.
In some embodiments the attachment portion on the connector extends at least part way around the retaining portion so as to present a plurality of different angularly spaced attachment regions at which the attachment portion of the spike may be selectively located.
The attachment portion on the connector may comprise a runner accepted in the slot in the attachment portion on the spike.
The complementary attachment portions may comprise indexing means for indexing relative movement of the attachment portions as the orientation of the connector is altered relative to the spike.
The indexing means may comprise a series of projections and recesses on the attachment portion provided on the connector, and a projection on the attachment portion on the spike, which is arranged to ride over a respective one of the projections on the connector as the connector is moved from one indexed position, determined by a respective recess to another.
According to another aspect of the invention there is provided an irrigation system comprising at least two ground spikes as defined above, and at least two of: a length of supply hose, a length of micro tube, an irrigation connector, and an irrigation outlet component, wherein each of said two ground spikes holds a respective different one of said at least two of: a length of supply hose, a length of micro tube, an irrigation connector, and an irrigation outlet component.
Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings, in which:
In such an irrigation system, the water supply hose 1 and outlet components 3 may be standard commercially available products. For example, the water supply hose 1 may be a length of standard garden hose.
As mentioned above, each irrigation connector arrangement comprises an irrigation connector 4 mounted to a ground spike 5 for securing the irrigation connector 4 and hence a carried supply hose in position, as schematically illustrated in
The irrigation connector 4 comprises a hose retaining portion 41 for holding the supply hose 1 as shown in

Referring particularly to
The main body 51 comprises a part circular cut-out 54 which is arranged as a micro tube grip, thus allowing the ground spike 5 to secure micro tube in position. A groove 55 (see
The lugs 53, part circular cut-out 54, groove 55, mounting portion 56 and attachment portion 57 can each be considered as respective holding portions. These holding portions differ from one another and are arranged for holding respective different components which will be used in an overall irrigation system.
The lugs 53 define a space between the main body portion 51 and the respective lug 53 which can act as a supply hose receiving portion. It will be noted that this region has a mouth of a dimension which is chosen for allowing the insertion of a supply hose diameter such that the lug 53 may be located over a supply hose when the ground spike is driven into the ground.
On the other hand, the part circular cut-out 54 and groove 55 are arranged to have a dimension which is suitable to accept micro tube. Thus the part circular cut-out 54 has a mouth of a smaller dimension than that between the lugs 53 and the main body 51.
The ground spike 5 comprises a pair of arms 57b which provide the attachment portion 57 for attaching an irrigation connector 4 to the spike 5. The arms 57b project from the main body 51 of the ground spike 5 towards one another. As such they define a first slot between the arms 57b and the main body 51 and a second slot between the arms 57b themselves. The arms 57b also provide a location at which a irrigation component can be attached. This is supplementary to the irrigation component mounting portion 56 provided in the side of the main body 51. In both cases a flange F (see
As mentioned above, the irrigation connector 4 is arranged to be orientatable at different angles relative to the ground spike 5. The irrigation connector 4 comprises an attachment portion 47 which is arranged to be complimentary with the attachment portion 57 on the ground spike 5. These complementary attachment portions 47, 57 allow the connector 4 to be mounted on the spike 5 and the orientation of the connector 4 to be varied relative to the spike 5. The attachment portion 47 on the irrigation connector 4 extends part way around the retaining portion 41 so as to present a plurality of different angularly spaced attachment regions at which the attachment portion 57 of the spike 5 may be selectively located.
The attachment portion 47 of the irrigation connector 4 comprises a runner 47 which is accepted in the slots defined by the arms 57 on the spike 5. The attachment portions 47, 57 comprise indexing means for indexing relative movement of the attachment portions as the orientation of the irrigation connector 4 is altered relative to the spike 5. The attachment portion 47 on the irrigation connector 4 comprises a series of projections and recesses 47a and 47b (see
In an alternative the projections 57a may be omitted. This reduces the force needed to move between indexed positions.
