Description

The invention relates to a sprinkler - in particular a surface, rectangular or square sprinkler sprinkler for gardening.

Sprinklers are in German usage as Sprenkler - derived from the English word Sprinkler - which in turn is mainly used in German in the fire fighting. The terms irrigation system, sprinkler system, sprinkler, sprinkler or sprinkler are also used for irrigation preparation or installation.

All garden plants need light and water. Sprinkler systems are particularly suitable for larger beds and garden areas that should be supplied with water evenly. The irrigation of garden areas is done manually with the watering can; All sprinkler systems are used to keep the vegetation moist and are powered by the flow pressure of the water, regardless of the construction method.

The impulse sprinkler or rocker sprinkler is placed on a tripod for irrigation of larger areas and operated via one or two nozzles; These sprinklers work with a jet of water and a nozzle, with which the water can be distributed in different throw directions on the beds or the lawn.

A simplified version of the impulse or oscillating lever sprinkler for correspondingly modest applications is the circular, circular or all-round sprinkler, with two water-powered, rotating, mostly kinked pipe nozzles with water-pressure-dependent operation.

Pop sprinklers are special sprinklers that are used to irrigate green areas - especially lawns - commonly known as lawn sprinklers or lawn sprinklers. Pop-up sprinklers are offered in different versions; There are plastic or stainless steel climbers, full or partial circle sprinkler with different nozzles.

A gearbox opponent is a ground-fed pop-up sprinkler whose gearbox is supplied with water pressure and rotates; The Revolver lawn sprinkler belongs in this type of construction. Gearbox reactors are usually part of a sprinkler system; They allow the targeted irrigation of certain garden areas.

Surface, rectangle or square sprinklers find their main application in smaller gardens and work with a spray or spray jet, which exits through several nozzles. The water pressure drives the most adjustable pivoting movement of the spray or spray jet, where the irrigated rectangle or square surface for beds or lawns results. The devices are usually operated on a mobile basis, with loosely laid tubing and flexible hose coupling; During a sprinkling process, the user manually detects various irrigation positions at different times.

Depending on the equipment, manufacturer and model, additional functions such as slipping clutches, vandalism protection or waterstop are available on the market when changing nozzles.

In the following, the state of the art of irrigation devices - in particular surface, rectangular or square sprinklers is appreciated as a sprinkler for the gardening technology; According to the prior art, depending on the application, a variety of types of irrigation devices - in particular of surface, rectangular or square sprinklers as sprinkler for the gardening equipment in use.

utility Models DE 20 2006 013 510 presents a fixed or displaceable or mobile device with a vertically arranged lawn sprinkler for home gardens or parks with water connection and electrical leads for z. B. solenoid valves, the capped lawn sprinkler is arranged vertically in a housing, the droplets of swarm is sprayed radially and the lawn sprinkler can change its altitude at the upper outlet of the housing in relation to this in the axial direction depending on the water pressure - and thus the water outlet amount - and the lid of the sprinkler in the rest position thereof forms a covering cap for the housing.

Since the hydraulic system is exclusively controlled by water pressure and no regulation is provided, oscillating relative movements between lawn sprinkler cylinder and nozzle can not be excluded up to a natural frequency of the system. The design of the hydraulic cylinder and the nozzle are not detailed.

The German utility model DE 20 2006 006 435 discloses a vertically disposed lawn sprinkler with horizontal water inlet, the bottom of a fixed unit, arranged above it from an axially fluid-driven rotatable unit, above a horizontally pivotable connector and a multi-nozzle assemblies equipped spray head consists, which is itself mounted axially rotatable, so as to change an inclined position of the spray head. A water pressure driven impeller drives an axially disposed planetary gear so that the first rotatable housing rotates together with the planetary gear about a sun gear; the rotational speed of the rotatable housing is determined by the gear ratio of the planetary gear set. The lawn sprinkler is very elaborately designed and consists of many parts. A water-pressure driven rotary part and a pivotable and rotatable spray head make the three-dimensional adjustability appear difficult.

By the German utility model DE 203 17 854 / US application US 7 191 958 a vertical Sprinkler with horizontal water inlet is presented as a lawn sprinkler - with the peculiarity of the adjustment of the angle of rotation - consisting of a rotatable guide plate, via which the water flow can be controlled so that it actuates an impeller, which in turn via a Transmission operates a rotatable disc on which a mounted via a movable angle-adjusting connection nozzle is installed. The rotatable guide plate is subjected to a force action to change its direction of rotation when a projection of the rotatable disc comes into contact with a positioning block of the upper lid housing of the sprinkler.

The rotation angle adjustment appears cumbersome and difficult to handle according to the use. The water pressure acts directly on the rotary drive, the setting angle of the spray parabola is adjustable.

Other publications relate to turret lawn sprinklers such as those of the American design patent US D540,428 , the European application EP 1 738 833 US Application US 2006/0273202, utility model DE 296 03 947 / US applications US D492 005, US D488 533 and US 2004/0227 009 and the utility model DE 203 09 365 / Chinese registration CN 2 626 221 and the American design patent US D498 513 ,

A circular sprinkler lawn sprinkler is the German utility model DE 296 01 880 disclosed; he is not subject to further considerations here.

The following consideration is limited to specific properties of surface, rectangle or square sprinklers as a sprinkler.

The Italian application IT 3 401 789 / European registration EP 0 394 653 / Canadian registration CA 2 014 887 presents a novel spray head of an oscillating lawn sprinkler. The spray head forms a straight hollow cylinder with longitudinally and in series mounted spray nozzles, wherein each half of the nozzles processed half a spray area and is aligned accordingly. Centrally located in the axial direction, opposite the spray nozzle row, there is a bore for the water supply, which takes place below the high-pressure cylinder via a further feed pipe. In the inlet pipe facing away from the hollow cylinder half a further hollow cylinder is fitted sealed rotatably fitted over the full half-length, whose end facing away from the inlet is provided with a knob to be operated from the outside. The knob remote from the end of the inner tube is cut so obtuse that the shortest end before the water inlet and the longest end immediately behind the water inlet ends O-ring sealed and form the two hollow cylinder a rotatable control valve. In a manual 360 ° rotation of the inner tube - depending on the direction of rotation - various water supply conditions go through, as Wasserzufuhrsperre, water supply right half pipe, water supply left half pipe, water supply both pipe halves and all intermediate states of water flow.

Since the hollow cylinder can only be made straight, the holes and the nozzle heads must have the spray orientation and form the sum of the desired blasting area. The nozzle heads offer no adjustment.

The swivel lawn sprinkler of the Italian booking IT 3 404 988 / European registration EP 0 363 717 US Application US 5 033 678 has a planar construction, each with an end bearing for receiving the convexly curved explosive tube with applied non-adjustable nozzles. The end bearing closest to the filter water plug is part of a water turbine drive box having an external, manually adjustable crank drive for limiting pivotal movement, and another rotary volume control device for manually controlling water volume. Trained as a pressure reducer control moves via a screw a longitudinally slotted water-flowed hollow cylinder within a tube cartridge, the set opening determines the flow rate.

The exposed crank mechanism is a source of environmental and handling hazards; the manual controls and the operator are exposed to irrigation during the setting mode.

The American application US 2007/0 221 756 presents a square sprinkler with replaceable nozzles. The lawn sprinkler is in essentially from a gear tray with outwardly facing feet, a drive part, a connecting part and a pivoting and adjustable explosive pipe. A water inlet, the drive part, a pivot adjustment, a bearing block 1 and the connecting part form a front device carrier part and a bearing block 2 with a clamping device a rear equipment carrier part. The bearing blocks are on their feet by means of each one right and left side, running in the direction of the explosive tube hollow support tube spaced and stable; the hollow cylindrical water-bearing explosive pipe is held on the one hand by the connecting part and on the other hand by the bearing block 2. The blast tube has water-carrying chambers with end inlet openings, which correspond with inlet and outlet openings of the connecting part. The blast tube has at its farthest from the bottom longitudinal direction axially extending recesses, which are provided with interchangeable, sealing, row arranged spray nozzle modules and sealed by means of a likewise hollow cylindrical shell with longitudinal recess relative to the spray nozzle positioning sealing.

The individual spray nozzles are not adjustable; the spray nozzle modules are interchangeable. The parts and assembly costs - especially with regard to the sealing function - are very high.

The European application EP 1 894 631 US Application US 2006/0 841 243 discloses an oscillating square sprinkler consisting of a rectangular frame with runners for receiving a cylindrical, swivel-range-adjustable drive unit with water turbine which acts on a pivotable, fluid-supplied high-cylinder explosive tube with a single-row, ball-bearing nozzle arrangement. The nozzle assembly forms an independent nozzle module and is fixed to the blast pipe and fluidly connected. About the equidistant nozzle assembly a griffbetätigbare pivoting guide plate with a coaxial, angular slot arrangement is slipped, the slots in the basic position coincides with the position of the nozzle and with the departure of the basic position by pivoting in the coaxial direction, the nozzle heads from the center, with the pivoting ever increasing aligns outwards in the direction of the blast pipe ends. About the pivotable guide plate, a fixed cover is slipped with extending in the axial direction of longitudinal slots, which assumes the correct position guidance of the nozzles when the position of the guide plate changes.

With the change in position of the guide plate is changed by changing the angular position of the spray nozzles irrigated surface, different slot patterns in the guide plate result in different nozzle orientations and irrigation patterns; the operation of the guide plate is carried out by handles in the middle of the blasting tube. The technical effort for the realization is high.

The Taiwanese application TW M 247 002 / French registration FR 2 860 997 / Canadian registration CA 2 469 725 concentrates exclusively on the drive and control block of an oscillating swivel sprinkler mounted on one side of the throttle-valve-controlled water intake side of a skid-mounted implement carrier.

The utility model DE 20 2004 000 736 and DE 20 2004 009 069 / Taiwanese applications TW 092 218 692 and TW 093 203 439 relates to a pivoting mechanism for a lawn sprinkler comprising a blasting control and operating unit mounted on one side of an explosive rack, the blasting control and operating unit comprising a gear-operated gear mechanism, a restrictor, a water inlet, a water outlet fitting, a main drive gear and an adjustment seat or an adjustment recording exists. A flow switching plate, a switching device and a support rod are rotatably mounted on a boundary groove of the adjustment seat. As a result, for pivoting back of a sprinkler body at the limiting end, the switching means is rotated on the limiting groove of the Einstellrille on the coupled with the gear-operated mechanism holding rod, whereby the flow control plate is moved without delay, so that the angle of the water outlet is precisely switched and a light and smooth operation of the invention equipped Lawn sprinkler is achieved.

With this device, a swing mechanism for a lawn sprinkler is provided, in which the switching operation is carried out easily and accurately, the switching and control of the water outlet are simple and accurate, but with the inclusion of a large number of parts.

The American design patent US D500 122 presents a tool carrier for an oscillating swing square sprinkler.

US Application US 2002/0 092 931 presents a design for a spray nozzle assembly for an oscillating pan-and-rectangle lawn sprinkler, wherein the spray nozzles consist of more than one nozzle shape and are arranged more than one row in order to eliminate the undesired 'puddling' To avoid effect.

The utility model DE 201 05 410 / English registration GB 2 373 161 / French registration FR 2,822,346 EP 0 788 039 A1 discloses a lawn sprinkler consisting of a down-to-earth rack provided end-to-end with a hose connector and two positioning elements mounted at a parallel distance therefrom, and two sprinklers mounted at a distance from each other on the rack such that the Blasting pipes are in communication with the hose connector and the blasting pipes are held on the frame by means of the two positioning elements, while the two blasting pipes are provided with a plurality of one or more rows in the longitudinal direction of the tubes arranged spray nozzles, wherein the blasting pipes beyond end with an adjustment are provided for adjusting the spray angle of the nozzles of the tubes. An arranged between the positioning and the hose connector 2-way water distribution valve allows fluid switching to the right or left side or both blasting.

Angle settings for the blast pipes and for the 2-way valve are made manually, a drive for the positioning and adjustment is not provided.

With the international application WO 1995/004603 / US Application US 8 101 651 a rectangular lawn sprinkler with cam-controlled variable irrigation pattern is presented. The proposed lawn sprinkler consists of a hollow cylindrical tube with on the one hand a water connection, a housed water turbine as a drive for the pivoting movement, a setting mechanism for the pivoting range and on the other hand a housed, rotatable selector switch for adjusting a portion of the spray nozzles. The pipe is carried by each by an initial and end support, wherein the feet of the supports are stabilized by running longitudinally connecting pipes. On the most remote from the bottom surface of the tube extends in the longitudinal direction of a single-row spray nozzle assembly, the centrally disposed over 11 - as well as above from the prior art - has known spray nozzles and each complementary to the pipe ends 5 other spray nozzles. These spray nozzles are controlled by means of a switching rod provided below the nozzles and provided with cam disks acting on the nozzle valves, which is operated manually via the distally mounted selector switch with 11 switching positions in order to carry out a specific irrigation pattern.

Here is created with a significant technical effort on parts and assembly times a device that is expected to achieve their goal, a lawn sprinkler application and setting during operation without sprinkling the user, not achieved because the edge nozzles are usually always directed to the outside and the Adjustment must be made on the device.

By the patent US 4 606 500 discloses a releasable coupling for the crank mechanism of an oscillating pivotable surface sprinkler. The sprinkler consists of two spaced by tubes bearing housing to accommodate a convex curved spray tube with single-row spray nozzles, a bearing housing in addition a water connection and the opposite housing a water turbine as a drive for the pivoting spray tube and a crank mechanism with eccentric and adjustment of the swivel range with control knob receives. The power transmission from the crank mechanism to the cylindrical spray tube via a closed to 3/4, clipped clamp with a notch as rotation, which is made to match a recess in the spray tube.

When the crank drive and the spraying tube are in use, the clamp will come loose from the end of the spray tube without damaging the gearbox or the drive.

With the German utility model DE 79 28 149 / English patent application GB 2 032 745 / Italian registration IT 22 941B-78 a Schwingarm lawn sprinkler is presented with a bottom-side skid frame, which is composed of two U-shaped bent metal pipe pieces which are inclined towards each other and carry with their converging ends on the one hand a V-upside-down storage and on the other hand, a housing for receiving a movement-generating device is determined. The housing has on the sprinkler side facing away from a water connection; the pressurized water is fed radially in the housing to a turbine rotor and continues to the facing end of the oscillating arm. The impeller acts via two worm gears on the output shaft with eccentric disc and toggle lever on a pivot bearing with angular adjustment and offset in operation by means of a pendulum motion the nozzle-prone, on the housing side facing endged Schwingarm in an angle-defined permanent pivotal movement.

With water turbine drive, a worm gear with two worm gears, a crank mechanism and a further mechanical translation with angular adjustment, the generation of the adjustable pivoting movement appears very expensive. The open crank mechanism speaks for a certain ease of maintenance, but not necessarily for safe handling. Nozzle adjustment is not provided.

The US patent US 4,166,578 presents an oscillating lawn sprinkler with convex curved blast pipe and water turbine drive, in which the non-adjustable pivoting movement via a double crank gear with gear reduction takes place.

An adjustability of symmetrical and asymmetrical pivoting range would increase the number of mechanical parts and the assembly cost considerably.

The American application US 3,823,874 presents a control for a water supply of a rotary lawn sprinkler, consisting of an electrically non-conductive, placed in the effective range of the sprinkler water tank with mounted in three different heights humidity sensors or with moisture-measuring resistance wires as sensors for a logic whose output signal on a controllable or switchable, the sprinkler supplying, water-bearing valve acts. In a dry collection container, the valve is opened, the sprinkler begins to spray - until the water level in the container reaches the top humidity sensor and the valve shuts off - until the lower switching state is achieved by evaporation of the water and the valve is switched back and the water flow is opened.

The parameter Time is for the control or the parameter Soil moisture is not intended for a control.

The German disclosure DE 1 965 958 presents a square sprinkler as a lawn sprinkler, wherein the spray openings in an angular range perform a pivoting movement, wherein the pivoting movement is effected via a two-stage reduction worm gear from a reversible liquid turbine and in which the spray openings are arranged in a pivotable housing which encloses the liquid turbine. The reduction gear and the turbine are supported by a centrally projecting into the cylindrical housing stationary axis, which also forms the pivot axis, and the fluid enters the housing of the device via the at least partially formed as a central hollow shaft axis; the construction becomes more compact, drive part and irrigation part are placed in a housing. A frame supporting and supporting the pivotable housing consists of two tube clamps arranged in V-shape - which also serve as skids for transport - which each terminate in the housing-carrying connecting parts. On the connection side, a manually operated swivel angle adjustment is provided between housing and connecting part.

Due to the compact design, the spray nozzle arrangement is relatively small; since the nozzles are arranged in a recessed plane of the housing cylinder, the holes must be formed according to the snap directions. An adjustability of the nozzles in terms of throwing distance and direction is not provided.

The two utility models DE 1 964 972 and DE 1 935 269 have ever mounted on a flat base plate area, rectangular or square lawn sprinkler for content with the special property that the pivoting range relative to the vertical center plane continuously - instead of in stages - from 0 ° to 90 ° is designed adjustable and beyond the possibility is given to move the rectangular blasting area asymmetrically with respect to the vertical median plane through the blast pipe axis. The output of the blast-water-driven turbine with a helical worm and a spindle drive is supplied to an eccentric, which makes a pivot-mounted rocker so adjustable adjustable by means of a Stellknopf- (asymmetry) and handle-guided (swivel range) adjusting lever, that the swing swinging movement about a pivot point opposite sprocket is transmitted to a fixedly connected to the pivot tube pinion.

For the purpose of uniform surface irrigation is the substantially harmonic motion sequence of the crank mechanism to a heart-shaped curve - from the Canadian patent publication CA 729 059 - added. In the reversal positions, the blast pipe no longer lingers, the edge strips lying parallel to the blast pipe are no longer raining more heavily than the surface in between.

The parts cost is large according to the functionality of the sprinkler and the manufacture of the parts is demanding due to the required eccentricity. Nozzle adjustment is not provided.

The German patent application DE 15 82 920 introduces a square sprinkler whose housing also carries a round sprinkler, a sprayer or a hose coupling for the connection of other sprinklers. In this way, a square sprinkler is formed, which can be brought by simple valve actuation either simultaneously or alone as a rotary sprinkler used. The working circuit for the square and rotary sprinkler is controlled by a single valve; However, they can also be formed by arranged in the leads of the square and Rundregners independent valves. The rotary sprinkler or the spraying device can also directly on the the sprinkler tube of the square sprinkler influencing poppet be fitted and be connected via the poppet hole either with the inlet for the Rectangular sprinkler or separable.

The simultaneous operation of square and round sprinklers can still be explained; Description and claims have defects in the reference numerals.

All publications presented are only partially or not at all suitable for the specific use of a sprinkler - especially not for a surface, rectangular or square sprinkler sprinkler for gardening.

The invention is therefore based on the object, a device according to the preamble of claim 1, a sprinkler - in particular a surface, rectangular or square sprinkler as Sprinkler for gardening - to create.

This object is achieved by the characterizing features of claim 1; to advantageous embodiments, the dependent claims.

The runner-mounted implement carrier with lateral water connection of the surface, rectangle or square sprinkler grows flat on the garden floor and tends to tip over; also depends on which hose, which diameter, which wall thickness and which water pressure is used. If the implement carrier of the area, rectangle or square sprinkler is also intended to be moved by hose movement, it will also leave its position during water turn-on or during vibratory operation by the water turbine in conjunction with a crank mechanism. Also, the weight distribution of water-filled hose to plastic-made lawn sprinkler can cause it to tilt, depending on the distance from height hose connection to the ground and the dead weight of the sprinkler.

Area, rectangle or square sprinklers as lawn sprinklers should also be designed and installed so that they provide a minimum of shade and leave behind lawn shadow marks. Therefore, the gear tray should be as fragile and 'translucent' as possible. The adjustment functions presented below are particularly difficult to make when the skid-type area, rectangle or square sprinkler is located on difficult, uneven terrain and to set and irrigate cleanly defined irrigation surfaces by nozzle manipulation.

In the case of setting functions whose properties often appear doubtful and whose handling is in part seeking assistance, the question arises of the necessity and use of such functions. The replacement of a nozzle plate on the swivel lawn sprinkler with subsequent testing of the sealing function certainly requires special technical understanding and manual skills. This handling also requires the knowledge of the technical function of a first and another nozzle plate as well as a judgment for their use, which must also include gardening and plant knowledge. The same applies to the sprinkler with external cam-controlled additional spray or spray nozzles with a selectable and adjustability of 11 positions. The swivel range adjustment by means of two stops can be required and useful in individual cases and will certainly be understood by the garden friend on the one hand and on the other still manageable. With the lateral or deep nozzle setting, the necessary manipulation of the technical device is already difficult, especially when settings in noisy operation. In the tube-in-tube valve, the functions of spraying right nozzle half, spraying left nozzle half, spraying both nozzle halves are from 0% to 100% water flow rate through a 360 ° rotation; Perhaps at this point a 4-speed or 8-speed tap changer would have made handling easier. The functionality and operation of the 2-Sprengrohr-sprinkler with independently pivotable spray and spray nozzle double rows by means of a 2-way valve must first be accepted and understood by the gardener friend.

The inventive novelty will be explained below by the description of an embodiment. Presented is a surface, rectangle or square sprinkler consisting essentially of

• - a swivel nozzle head with adjustable and closable individual nozzles
• - A cylindrical drive housing with water turbine / 2-way flip-flop valve and adjusters
• - A cuboid adapter with cylindrical receptacle and water connection
• - A plug foot set of four angled hollow cylinders / tubes
• - a set of holders with insertion tips, double.

The sprinkler is - unlike the previously presented - a standalone unit and has a modular design; the parts can be made of plastic and / or aluminum. Thanks to its 'open' design, the device forms hardly damaging shadows and its four ground tips, the device is immovably stable, can also - provided with a dragonfly - are aligned according to the ground surface geometry for a desired sprinkling surface and leaves no visible traces in the garden soil. In disassembled state, the feet and the brackets can be easily mounted; The length dimensioning of the feet is freely selectable or can be made selectable.

The adapter is preferably a hollow body made of plastic; He has four holes for receiving the feet. The water supply takes place centrally and vertically downwards; It is the connection of a commercially available hose coupling provided. Even with the connection of strong hoses for water supply creates no twisting or other moment of force, which would be absorbed by the device and compensate. Local shifts of the sprinkler for this reason are eliminated. The water connection opposite the adapter surface is cylindrical and adapted to the drive housing pronounced for the purpose of integrally receiving the same. The water supply or the water is passed through the adapter in the drive housing.

The drive housing includes a pressurized water-driven drive according to the prior art z. B. in the form of a water turbine, with an implementation of the rotational movement in a pivoting movement, or z. B. a water-controlled, reversible 2-way flip-flop valve, with an implementation of the linear movement in a pivoting movement. Two independent, easy-to-use adjusters are provided as limiters for the symmetrical or asymmetrical pivoting movement. A built-in pressure reducer or pressure control valve allows manual adjustment of the water pressure by means of a in the drive housing taken in rotary knob. The cylindrical drive housing contains each end face a rotary and / or sealed bearings for the purpose of mechanical and fluidic recording of the pivotable nozzle head.

The pivotable nozzle head is a flat, made of plastic, dense hollow body whose surface facing away from the ground convex, the spray and spray angles, is formed. This surface carries a number of adjustable and closable individual nozzles. Within the nozzle head and below the nozzles there is a water channel adapted to the required water volume to be sprayed or sprayed which is connected to the water-bearing drive housing at least via a rotary / sealing bearing and via the path of the pressurized water hose, the hose coupling, the water turbine / the 2-way valve, the drive housing and the rotary / sealing bearing is supplied with water.

The adjustable and closable individual nozzles each allow a volume-regulating beam adjustment of which hard and vice versa and also serve the width adjustment - in the axial direction of the drive housing - the irrigation area, while the symmetrical or asymmetric length adjustment of the irrigation area is made by the manually adjustable limiter of the swivel range. Through the directional water channel all nozzles have the same volume of water available; by changing the cross section of the water channel, the pressure is maintained.
