[0001] A WATERING DEVICE

[0002] TECHNICAL FIELD

[0003] The present disclosure relates to a watering device such as a sprinkler system. In particular, the present disclosure relates to a coupling system of a sprinkler head with a main body of the sprinkler system.

[0004] BACKGROUND

[0005] A variety of irrigation systems are used throughout the world for irrigating crops and groves. One common system used for irrigation is a sprinkler system having a plurality of sprinkler heads coming from a central water supply line for distributing water over a surface area. These systems may use a moving supply line for irrigating food crops, groves and the like. The sprinkler units may have replaceable nozzles so that different nozzles may be selected and mounted in the sprinkler unit to achieve a desired range or rate of coverage or simply to replace a defective nozzle. An irrigation system may also have many different sprinkler units of the same type with each having different nozzles and it is sometimes desirable and necessary to change the nozzles often for a given area to obtain an optimum irrigation of an area of coverage. This requires maintaining different sprinkler nozzles and selecting the nozzle for a particular coverage after a sprinkler system is installed.

[0006] Many current nozzles are removably attached to a sprinkler head in which the nozzle or a cover for the nozzle is threadedly attached which requires unscrewing a nozzle or cap for the nozzle, finding a replaceable nozzle, and attaching the new nozzles onto the sprinkler unit. This is sometimes difficult because the nozzle is positioned so it cannot be gripped easily to unscrew the nozzle or to simply pull out the nozzle in the case of a press-fitted nozzle. It is also necessary to have a replacement nozzle handy for exchanging nozzles on the sprinkler head.

[0007] An example is provided by Chinese utility model CN 212728316 U (hereinafter referred to as the ’316 reference). The ’316 reference discloses a sprinkling irrigation equipment used in gardens which is convenient to change. The sprinkling equipment has a support body and detachable nozzle base set up on the support body. A frame body comprises a pipe body, a connecting body, a fixing ring, and a plurality of fixing rods, wherein the connecting body is arranged at one end of the pipe body and is used for being connected with the spray head base. The fixing ring is arranged in the middle of the pipe body, the fixing rods are arranged on the outer wall of the fixing ring, and connecting mechanisms which are to detachably connect the spray head base are arranged on two sides of the connecting body. The coupling mechanism for nozzle seat detachably fixes annular groove on the connector with the nozzle seat.

[0008] A further example from a different technical field is provided by US patent US 9,086,180 B2 (hereinafter referred to as the ’ 180 reference). The ’ 180 reference discloses a quick connect system for the assembly of underground mining dust and fire suppression systems. The quick connect system can eliminate the need for threading a pipe with couplings during the installation and thereby reducing installation time. The system is simple to maintain and reduces high installation and maintenance labor costs. The system uses male and female ported fittings and horseshoe pins. Further, with the ease of installation and convenience of the quick- change coupling system of the ’ 180 reference, the individual pipe sections can be attached to any stable structure to allow for compliance with regulatory stipulations. The individual pipe section can be inserted together utilizing a horseshoe clip with a small hammer, and spray angle and positioning is accomplished using pliers. Disassembly and re-installation are cost-effective using a screw driver to remove the horseshoe clip.

[0009] Hence, the ’ 180 reference provides a self-contained and cost efficient system for quick installation of underground mining applications. Thereby, the ’ 180 reference discloses that the system aims to provide an easy way to install specific sprinkler heads for use in an underground mining operation.

[0010] However, the ’ 180 reference does not describe any need or interest in a locking element which allows changing between different types of sprinkler heads. Furthermore, the ’ 180 reference does particularly not disclose a locking element comprising a locking contour and a release contour.

[0011] A further example from a different technical field is provided by the PCT application WO 2007 / 109729 Al (hereinafter referred to as the ’729 reference). The ’729 reference discloses a fluid connection using quick connects for connecting building and housing water delivery systems to various fluid controls, such as faucets, showerheads, toilets, through valves or fittings. In a building and housing water delivery system, a stop valve housing is mounted between two fluid conduits by respective quick connectors, each comprising amongst others a housing and a retainer which is fitted to the housing. The quick connect may be delivered in a shipping or storage position in which the retainer is snapped onto the housing in a movable way, and may be brought into a latched position when the quick connect is installed and during its entire use. In the latched position, the end portion of the fluid conduit is fully seated in and lockingly engaged with the housing. In this position, conduit attachment legs engage the attachment groove to axially retain the fluid conduit. Additionally, a locking flap provided on one leg of the retainer is in interlocking engagement with the retainer’s other leg, and in axial engagement with the end portion of the fluid conduit. Hence, the ’729 reference discloses a self-contained and quick attached locking arrangement which permits the rapid attachment of the valve assembly to each fluid conduit within a building and housing water delivery system. Thereby, the ’729 reference discloses a connect which allows quick and easy installation.

[0012] However, the ’729 reference does not describe any need or interest in a locking element which allows changing between different types of sprinkler heads. Furthermore, the ’729 reference does particularly not disclose a locking element comprising a locking contour and a release contour.

[0013] A further example from a different technical field is provide by the German utility model DE 202017 105 078 U1 (hereinafter referred to as the ’078 reference). The ’078 reference discloses an assembly for providing a rotatable connection between two water-bearing armature or fitting parts. When an end of the second fitting part is inserted into an end of the first fitting part, a clip for axially fixing the two fitting parts together, is inserted such that a connection of the clip with a restriction of the second fitting part and a groove in the first fitting part is established. Further, the ’078 reference discloses that the clip provides a axial fixation which allows a rotatable movement of the two fittings with respect to each other.

[0014] Hence, the ’078 reference provides a self-contained and cost-efficient rotatable connection of two armature or fitting parts, in which the clip ensures an axial fixation.

[0015] However, the ’078 reference does not describe any need or interest in a locking element which allows changing between different types of sprinkler heads. Furthermore, the ’078 reference does particularly not disclose a locking element comprising a locking contour and a release contour.

[0016] SUMMARY OF THE INVENTION

[0017] According to an aspect of the present invention, the watering device comprises a main body comprising a liquid inlet section for receiving liquid from a source, and a liquid-bearing section for guiding liquid from the liquid inlet section to a sprinkler head. The sprinkler head comprises at least one nozzle, a coupling section, and a locking element, wherein the liquid-bearing section and the coupling section are formed such that the sprinkler head is releasably mountable to the main body for enabling a flow of liquid from the liquid inlet section to the at least one nozzle. The watering device is characterized in that the locking element comprises a locking contour and a release contour, extending in a common plane, wherein the locking element is movable between a locking position and an unlocking position by a movement in a plane which extends substantially perpendicular to the liquidbearing section. Further, in the locking position, the locking contour of the locking element is in functional engagement with the liquid-bearing section such that the sprinkler head is immovable coupled to the main body, and further, in the unlocking position, the release contour is in functional interaction with the liquidbearing section such that the sprinkler head is demountable from the main body. The locking element provides an easy and user-friendly means to lock the sprinkler head with the main body of the watering device. The locking element allows for easy locking and thereafter unlocking of the sprinkler head with the main body with just a simple manipulation of the locking element. The user may find it easy to change between different types of sprinkler heads as the process of changing does not require a lot of effort therein. The user may grip with one hand the sprinkler head and with the other hand actuate the locking element. Hence, a convenient to use and easy to maintain watering device may be providable.

[0018] According to an exemplary embodiment of the present invention, the locking contour and the release contour are both formed planar and in a common plane. Hence, a space-saving locking element and subsequently a small watering device may be providable.

[0019] According to an exemplary embodiment of the present invention, the common plane is the plane extending perpendicular to the liquid-bearing section. Hence, a compact watering device may be providable.

[0020] According to an exemplary embodiment of the present invention, the locking element is movable between the locking position and the unlocking position by a one-handed movement in the plane. Hence, the sprinkler head may be changed by a user in an easy and convenient way.

[0021] According to an exemplary embodiment of the invention, the liquid-bearing section comprises a recess, particularly a circular recess. The recess allows for an engagement means for the locking element to interact with the liquid-bearing section of the main body, both with the locking contour and the release contour.

[0022] According to an exemplary embodiment of the invention, the locking contour is formed such that the locking contour interacts with the recess in the locking position. The interaction of the locking element with the recess in the locking position ensures that the sprinkler head remains suitably coupled with the main body. Further, the release contour functionally interacts with the recess in the unlocking position such that the sprinkler head may be movable relative to the main body. The release contour surrounds at least partially the recess in the unlocking position. According to an exemplary embodiment of the invention, the release contour is configured such that when the release contour is positioned at the liquidbearing section, the release contour is in functional interaction with the liquidbearing section, and the watering device is in the unlocking position. Further, the release contour is positioned adjacent to the locking contour. The release contour allows the sprinkler head to be decoupled with the main body as the interaction of the release contour with the recess allows the relative movement of the sprinkler and the main body. The release contour and the locking contour may both be formed planar and in one common plane which extends substantially perpendicular to the liquid-bearing section. Further this plane is the same plane in which the one- handed movement of the locking element takes place.

[0023] According to an exemplary embodiment of the invention, the sprinkler head is replaceable by another sprinkler head, particularly of a different type of sprinkler head. As the engagement and disengagement of the sprinkler and the main body is easily facilitated with, particularly one-handed, manipulation of the locking element, different types of sprinkler heads may be easily and conveniently used therein.

[0024] According to an exemplary embodiment of the invention, the locking element is movable between the locking position and the unlocking position by a linear movement exclusively in the plane extending perpendicular to the liquidbearing section. A simple push / pull with solely one hand to affect the linear movement of the locking element, allows for switching between the locking position and the unlocking position.

[0025] According to an exemplary embodiment of the invention, the locking element is formed such that the locking element is linearly movable between the locking position and the unlocking position by a linear movement in the plane. Planar movement allows for easy engagement and disengagement of the locking element with the recess of the liquid-bearing section.

[0026] According to an exemplary embodiment of the invention, the locking element comprises a gripping part, a first arm and a second arm together defining a substantially U-shaped contour, and the first arm and the second arm together defining the locking contour adjacent to the U-shaped contour. Each of the first arm and the second arm defines a release contour, wherein the release contour extends away from the locking contour. Such a structure provides a stable configuration for the whole assembly in both the locking position and the unlocking position.

[0027] According to an exemplary embodiment of the invention, each of the release contour comprises a snap-fit element at its free end. A snap-fit element allows for easy coupling and decoupling of the locking element in the locking position and the unlocking position with respective components.

[0028] According to an exemplary embodiment of the invention, the locking element is movable between the locking position and the unlocking position by a rotational movement in the plane. A simple, particularly one-handed, rotation to affect the rotational movement of the locking element, allows for switching between the locking position and the unlocking position.

[0029] According to an exemplary embodiment of the invention, the locking element is formed such that the locking element is rotatably movable between the locking position and the unlocking position by a rotational movement in the plane. Planar movement allows for easy engagement and disengagement of the locking element with the recess of the liquid-bearing section.

[0030] According to an exemplary embodiment of the invention, the locking element comprises a gripping part, and a planar body coupled to the gripping part. The planar body defines an opening adapted to receive the liquid-bearing section therein, and wherein the planar body comprises the locking contour and the release contour. The opening due to its shape and subsequent functional interaction with the liquid-bearing section allows for easy and efficient locking and unlocking of the sprinkler head.

[0031] According to an exemplary embodiment of the invention, the opening has a shape corresponding to an outer shape of the liquid-bearing section. This allows for the liquid-bearing section to pass through in the unlocking position and disallows movement of the liquid-bearing section therethrough in the locking position. According to an exemplary embodiment of the invention, the opening has a non-circular shape, more particularly the opening has an oval shape. The noncircular shape, in particular the oval shape allows for two different configurations corresponding to the locking position and the unlocking position between the locking element and the liquid-bearing section.

[0032] According to a further aspect of the present invention, a method of coupling a sprinkler head to a main body of a watering device is provided. The method comprises providing a locking element. The locking element has a locking contour and a release contour extending in a plane, wherein the plane extends substantially perpendicular to a liquid-bearing section. The method comprises providing a liquid-bearing section of the main body of the watering device. The liquid-bearing section comprises a recess. The method comprises positioning the locking element with the liquid-bearing section of the watering device. The method further comprises moving the locking element therethrough from an unlocking position to a locking position such that the locking contour interacts with the recess, and couples the sprinkler head with the main body. The method allows for an easy engagement and disengagement of the sprinkler head and the main body of the watering device. A user may easily change between different types of sprinkler head as per application requirements.

[0033] Before discussing the invention with the help of the drawings the invention will be briefly discussed in general. A watering device is provided that comprises a main body and a sprinkler head, wherein the sprinkler head is releasably mountable to the main body. The main body comprises a liquid inlet section, and a liquid-bearing section for guiding liquid from the liquid inlet section to the sprinkler head. Further, the sprinkler head comprises at least one nozzle, a coupling section, and a locking element. The locking element is configured to allow releasable mounting of the sprinkler head to the main body. For releasing or unlocking the sprinkler head from the main body, the locking element is required to be pulled, while for mounting or locking the sprinkler head to the main body, the locking element is required to be pushed.

[0034] The watering device according to the present invention may not require any additional tool to unlock and lock the sprinkler head with the main body. The at least one nozzle may be fast to clean, and the spray patterns may be easily changed by changing the sprinkler head releasably mounted to the main body.

[0035] According to an exemplary embodiment of the invention, the watering device may comprise the changeable sprinkler head that may be changeable without using any tool. The sprinkler head may comprise the locking element that may be used for unlocking and locking the sprinkler head to the main body.

[0036] Other features and aspects of this invention will be apparent from the following description and the accompanying drawings.
