Definitions

  • the present specification describes and claims a sprinkler system for watering lawns or beds of plants.
  • the sprinkler system comprises a hollow body pivotally mounted on a stand and arranged to receive and carry water under pressure, several openings being provided in the wall of the body, and a nozzle carrier in which several spray orifices are provided, the spray orifices pointing in different directions and each orifice being connectible to one of the openings in the body wall.
  • the present invention relates to a sprinkler system for watering lawns or beds of plants.
  • the present invention relates to a sprinkling system
  • a sprinkling system comprising a hollow body pivotally mounted on a stand and arranged to receive and carry water under pressure, a wall of the body being provided with several spray orifices pointing in different directions.
  • a sprinkling system is known from British Pat. Specification No. 1296664.
  • the spray orifices are located in the housing which encloses a driving turbine and transmission gear. In order to achieve a large range of spray in the longitudinal direction of the lawn sprinkler, they are designed as diverging bores.
  • Such a sprinkling system is constructed in an extremely compact manner and it operates excellently for small and medium areas to be sprinkled. If a larger area is to be covered, however, this can be accomplished only by the provision of a farther-reaching jet from the individual spray orifices. It is relatively difficult to provide the diverging orifices in the housing, made of plastics material. An economic machining is possible only by means of a special drilling device which drills simultaneously the numerous diverging holes. Owing to the complexity of the moulds it is almost impossible and economically unsound, to mould directly the diverging spraying orifices. The bores can only be realized cylindrically and it can easily happen, when a drill is pushed through, that a plastic chip is not torn off, and, during subsequent operation, is moved under the pressure of the water so as to block the spray orifice.
  • sprinkling systems which comprise a swivelling curved tube, through which flows the water. Into this tube are inserted individual nozzles generally made of metal. Such sprinkling systems are extremely expensive in their manufacture and assembly.
  • a sprinkler system comprising a hollow body pivotally mounted on a stand and arranged to receive and carry water under pressure, several openings being provided in the wall of the body, and a nozzle carrier in which several spray orifices are provided, the spray orifices pointing in different directions and each orifice being connectible to one of the openings in the body wall.
  • the present invention now enables the spray orifices in the nozzle carrier to be separately machined.
  • the nozzle carrier with the spray orifices can be injection moulded in one piece from plastics material.
  • the spray orifices and their feed ducts can be given optimum design, so that the farthestreaching and most favourable spray jet is achieved.
  • the feed ducts preferably have a larger diameter than the spray orifices and taper towards said orifices.
  • the spray orifices are located within the region of pluglike projections on the nozzle carrier, which projections are inserted from the outside of the hollow body into the separate openings in the body wall.
  • the attachment of the nozzle carrier from the outside makesassembly easier.
  • special measures have to be adapted for the sealing and for the absorption of the possibly appreciable pressure differential between the hollow body and the outside atmosphere. This problem is overcome by de-,
  • ' lugs may be provided which extend from each projection and have thickened regions which, when the projections are inserted in the openings, engage the body wall and retain the nozzle carrier in position.
  • one spray orifice is provided in the region of each projection and a feed duct leading to the spray orifice passes through the projection.
  • the nozzle carrier has a generally strip-like configuration in which the projections are formed, the parts of the carrier between the projections, covering part of the body wall when the projections are inserted in the openings. In this manner, even though the individual spray orifices are located in separate openings an integral nozzle carrier is formed, which not only facilitates the manufacture by allowing the production in one piece of a number of nozzle components, but above all facilitates the assembly of the sprinkler.
  • the spray orifices may be designed so that a single, relatively large spray orifice provides satisfactory performance, where several small orifices liable to become clogged were previously needed. This makes it also possible to arrange the spray orifices in a row, one behind another. As a result of the construction now possible, there need be no misgivings that the spraying jet, owing to clogging up or the like,.might assume a wrong direction and that as a result an area would fail to be sprinkled.
  • the hollow body has a curved shape to allow for the accommodation of the spray orifices in the appropriate diverging directions.
  • the hollow body can have a planar surface in which the openings are provided, the nozzle carrier being in the form of a substantially plamar strip, the feed ducts to the spray orifices being arranged so that they diverge.
  • the nozzle carrier can be designed so that the spray orifices and feed ducts are initially substantially parallel to each other, the nozzle carrier being of curved configuration.
  • the carrier can then be built into the lawn sprinkler by bending the carrier, the flexible parts between the projections facilitating this action, thus providing the diverging spray orifices.
  • the nozzle carrier with the spray orifices is manufactured, as is also possible, as a substantially straight part in one piece from plastics material, it is necessary to provide a number of slides in the injection mould, which slides carry the cores for the diverging spray orifices and feed ducts. Whilst it is true that this manner of manufacture is considerably simpler and less expensive than the known methods of manufacture, it can be simplified still further in the described former manner.
  • the nozzle carrier which ultimately is to be of straight, i.e., planar shape, is manufactured in curved shape so that its subsequently diverging orifices are all parallel, it is then possible to operate with a mould having only two pieces, one side of which carries all the cores for the spray orifices. After moulding, the flexibility of the parts of the nozzle carrier between the projections, facilitates the release of the nozzle carrier from the mould. This flexibility also allows the nozzle carrier to be straightened and attached to the hollow body.
  • outlets of the spray orifices are preferably each provided in a part spherical projection on the nozzle carrier, the outlets being part spherical depressions in said part spherical projections, the common centre line of each spray orifice and associated feed duct, passing approximately through the centre of curvature of the part spherical projection in which the orifice and feed duct are formed.
  • This design known in itself, ensures that no deflection of the jet is produced by outlet orifices cut off at an angle, but in addition offers advantages in manufacture in that the pins forming a mould for the spray orifices obtain effective guidance in the spherically shaped parts of the mould.
  • the hollow body may form the housing of the lawn sprinkler enclosing the driving turbine and a transmission gear. In this manner all the mechanical parts are protected and no additional leakage losses etc. need be feared.
  • FIG. 1 shows a lateral view of an embodiment of the sprinkling system constructed in accordance with the present invention
  • FIG. 2 shows a partly broken off longitudinal section of a detail of the sprinkling system in FIG. 1,
  • FIG. 3 is a plan view of a section of the detail represented in FIG. 2, viewed in the direction of the arrow in FIG. 2,
  • FIG. 4 is a section corresponding to FIG. 2 of a modified embodiment of a nozzle carrier
  • FIG. 5 is a schematic representation of a nozzle carrier and a plastic injection mould for its fabrication.
  • a sprinkling system 11 which comprises a hollow body 12 forming the main housing.
  • This hollow body 12 is constructed of plastics material and has a generally oblong configuration, a substantially cylindrical bulge 13 being provided at one end of the body. Inside the substantially cylindrical bulge 13 are accommodated a driving turbine 14 and a transmission gear 15 for producing a swivelling movement of the sprinkler about axis 19, these components being represented schematically by broken lines.
  • Two adjusting rings 16 allow the range of swivelling movement possible by the housing in both directions to be adjusted independently.
  • End pieces 17 provided at each end of the sprinkling system carry bearings which allow the housing to pivot about axis 19 these end pieces being joined to one another by stand bracket 18.
  • a connector in the form of a connecting nipple 20 is provided coaxially with the swivel axis 19, for the supply of the water.
  • the sprinkling system operates with a reversible turbine l4 and may be largely constructed and operated as described in German Pat. Specification 1,912,315.
  • a nozzle carrier 21 which carries spraying orifices 22 (FIG. 2), is arranged on the upper straight generatrix of the hollow body 12.
  • the nozzle carrier 21 is injection moulded in one piece from plastics material and has the shape of a strip in which the spraying orifices are provided.
  • the spraying orifices 22 are arranged in one row which extends along a line substantially parallel to the axis 19.
  • the spraying orifices 22 are provided in nozzle blocks 23 formed in the nozzle carrier, the nozzle blocks being joined together by striplike connecting parts 24.
  • the connecting parts 24 are moulded relatively thin, so that they are very flexible and permit bending of the carrier.
  • Each nozzle block is provided with one spraying orifice 22, each spraying orifice comprising a feed duct 25 pointing towards the inside of the hollow body 12, a taper 26 and the nozzle section proper 27, the outlet cross-section of which is smaller than the cross-section of the feed duct 25.
  • Each nozzle block 23 has a plug-like projection 28 extending from the adjacent connecting parts 24 of the nozzle carrier, into the inside of the hollow body 12, the round outside wall of which projection 28 is made slightly conical.
  • the upper section of each nozzle block 23 extending above the connecting part 24 consists of a projection 29 having a spherical surface.
  • a likewise spherical depression 30 is provided at the point where the outlet edge of the spraying nozzles 22 is situated.
  • the direction of spraying of the spraying orifices 22, which is symbolized by the centre line 31 of each spraying orifice consisting of feed duct 25, taper 26 and nozzle section 27, varies depending on where the spraying nozzle is situated.
  • the directions of spraying diverge, so that the outer spraying orifices, i.e., the orifices adjacent end pieces 17, spray most strongly away from the sprinkler, whilst the spraying orifices near to the middle of the sprinkler, spray almost perpendicularly out of the hollow body 12.
  • FIG. 2 illustrates spraying orifices provided towards each end of the sprinkler, and in a middle section of the sprinkler.
  • a fairly good retention effect is achieved by the normal pressing in of the projections in the openings 32.
  • a joint may also be achieved by fusing of the two parts.
  • FIG. 4 is presented a further kind of attachment between the nozzle carrier and the hollow body.
  • Each nozzle block 23' only one of which is illustrated, has in the region of its lower edge, as viewed in FIG. 4, a retaining device 34 which is formed by resilient plastic lugs which have thickened portions at their lower ends.
  • the lugs flex allowing the thickened portions of the lugs to pass therethrough, the lugs returning to their normal configuration when the projection has been pressed right in, the thickened portions of the lugs engaging the inner surface of body 12 to retain the nozzle carrier against the body 12.
  • FIG. 5 shows a nozzle carrier 21', which in most details may correspond to the nozzle carrier 21 described previously, during its fabrication.
  • the nozzle carrier comprising the spraying orifices, etc., is made in one piece by plastic injection moulding.
  • the mould for this purpose, consisting of two mould halves 35, 36 which can be displaced in relation to one another in the directions indicated.
  • the presentation has been considerably simplified. It can be recognized, however, that the nozzle carrier 2] lies curved in the mould, in such a way that the subsequent outside (on the top in FIGS. 1 and 2) is located on the inside of the arch.
  • the curvature is dimensioned so, that the centre lines 31 of the spraying orifices are all parallel to one another.
  • the cores 37 in the form of pins forming the spraying orifices during the moulding process can also be arranged all parallel to one another on one mould half 36.
  • the recesses in the mould half 35, in which the projections 28 are formed are displaced relative to each other by angular amounts corresponding to the required angular relationship of the spraying orifices.
  • the nozzle carriers 21 need not differ from the nozzle carriers described above in inserted condition.
  • the flexible connecting part 24 allows the nozzle carrier, as described above, to be straightened and fixed to hollow body 12. The spraying orifices will then diverge again and ensure the desired large dimension of the area to be sprinkled.
  • the present invention brings about a number of advantages. It makes it possible for the first time to provide in an economic manner a sprinkling system, the diverging spraying orifices of which have a wide range of sprinkling. Not only the length and the tapering form, which is approximating to the ideal form of outlet, of the spraying orifices ensure a good range of sprinkling, but also the fact that the inside faces of the feed duct, the taper and the nozzle section may have an excellent surface quality.
  • the flexible connecting part 24 not only facilitates the ease of fabrication described, but also ensures that the projections can be inserted one after the other, which facilitates assembly.
  • nozzle carrier small dimensional differences between the nozzle carrier and the hollow body 12 can easily be absorbed.
  • manufacture in one piece of the nozzle carrier is particularly preferred for economic reasons, but alternatively prefabricated nozzle inserts may be joined together, or be injected into a strip.
  • a sprinkler system comprising a stand, a hollow body pivotally mounted on the stand and adapted to receive and carry water under pressure, a plurality of openings being provided in a wall of the body, and a one-piece nozzle carrier having formed integrally therewith a plurality of plug-like projections, each projection being inserted in an opening in the body wall and the projections being secured to portions of the body wall surrounding the openings therein, fluid passages being formed at least in part in the projections and communicating with the interior of the body, the passages directing fluid sprays outward of the body and being oriented relative to one another such that the respective fluid sprays are directed in different directrons.
  • each fluid passage includes a feed duct and a spray orifice to which the feed duct is connected, the feed duct having a larger diameter than the spray orifice and tapering toward said orifice.
  • a sprinkler system according to claim 1 wherein flexible lugs are provided on the projections, which lugs retain the nozzle carrier against the body, when pressed through said openings.
  • each fluid passage includes a feed duct and a spray orifice to which the feed duct leads.
  • nozzle carrier is of generally strip-like configuration, the parts of the nozzle carrier between the projections covering the hollow body between the openings, when the projections are inserted one in each opening.
  • a sprinkler system wherein a feed duct connects with each spray orifice, the feed ducts immediately after manufacture of the nozzle carrier extending substantially parallel to each other, the nozzle carrier being generally arcuate so that said feed ducts diverge away from one another when the nozzle carrier is straightened to a substantially planar configuration.
  • a sprinkler system according to claim 1 wherein a driving turbine and a transmission gear are located in the hollow body for pivoting the system, the body forming the housing of the system.
