- This object is achieved in that the switching element is designed to be elastic in its positioned at the level of the end stops contact area so that the contact area at an overload from the displacement of the end stop recedes, and that means are provided to the Kojitakt Scheme at a defined position in the rotation angle range to raise between the two end stops from the Anlagengewichenen position again.
- the inventive solution damage to parts of the device and in particular damage to the switching element can be avoided.
- malfunctions are avoided, since the means for erecting are designed such that the contact area always reappears between the two end stops, which cause the direction reversal of the switching element.
- the solution according to the invention is suitable both for square sprinklers whose control components have an approximately horizontal axis of rotation, and for sprinklers or sprinklers with a vertically oriented axis of rotation, in particular so-called pop-up sprinklers.
- the contact region of the switching member is designed to be elastically yielding force-dependent.
- the contact area deviates elastically yielding only from a defined load limit.
- additional functions can be assigned to the contact area.
- the elastic deflection is done by buckling.
- a defined loading mode from which certain functions take place, can be provided.
- the contact region is preferably designed as elastically bendable spring element.
- the spring element In the unloaded position, the spring element is dimensionally stable and preferably rectilinear. If the corresponding load limit is exceeded, the spring element buckles elastically.
- the necessary force or load, from which the spring element buckles, is in the invention on the one hand by a corresponding accordingly designed by the physical properties of the spring element, wherein in particular its spring constant and its shape, are decisive achieved.
- a load limit of the contact area in which the contact area gives way elastically, is higher than a load required for switching the switching element. This ensures that the contact region is formed so stiff or dimensionally stable that it fulfills the function of switching the switching element functionally reliable.
- the device according to the invention has an overload clutch, which provides a decoupling of a transmission for rotating the control component in case of overloads.
- overload protection prevents destruction of the transmission in case of improper operation or in case of unforeseen blocking of the control component.
- the switching member comprises a tiltable switching pin, which is provided with the elastically resilient Xontakt Scheme.
- the switching pin preferably protrudes from the housing part of the device, which comprises the gear.
- the resilient contact portion is provided at a free end portion of the switch pin.
- the switching pin is advantageously ter manner as acting on a rocker rocker arm executed, with the rocker arm is rigidly connected to the rocker switch. A tilting of the rocker arm thus inevitably leads to a switching of acting as a switching valve rocker switch.
- the switching pin is arranged eccentrically to a rotational axis of the control component, and the contact area protrudes axially into at least one stationary functional part, which flanks the contact area both radially inwardly and radially outwardly. This ensures that the contact area can avoid either inward or outward.
- the functional part has an annular groove, into which the contact area protrudes, and which flanks the contact area both radially inwards and radially outwards.
- the stationary functional part is associated with an end stop.
- the at least one stationary functional part is to be understood as meaning a functional part which remains stationary in the watering operation of the device relative to the rotatable control component. An adjustment of the functional part in order to adjust the at least one end stop, however, is possible.
- the stationary functional part is in addition to its adjustment with a lock, preferably in the form of a detent, provided, which ensures the stationary positioning in the irrigation operation of the device.
- the stationary functional part is designed as adjustable relative to the housing part and lockable in different positions adjustable collar.
- the adjusting ring is rotatable coaxially to the axis of rotation of the control component.
- a further adjusting ring is provided adjacent to the first adjusting ring as a further functional part, which is adjustable to the housing part and lockable in different positions.
- the contact region projects axially into both adjusting rings, and the further adjusting ring is provided with the second end stop.
- the two adjusting rings thus comprise the two end stops for the contact area in order to effect the switching of the switching element.
- both collars are provided with Ringnutabêten so that the contact area is moved in the irrigation mode of the device in coaxial with each other adjacent annular grooves of the collars between the end stops.
- both adjusting rings are designed to be identical and mounted to each other in reverse mounting positions. This makes it possible to produce both adjusting rings made of plastic in the same mold. The production costs can thereby be kept low.
- control component in the vicinity of the contact area provides a bending edge and an escape area, in which the contact area is positioned in its elastically bent deflection position.
- the buckling edge in conjunction with the escape area allow a defined buckling of the contact area, in particular of the spring element, and a defined positioning of the spring element in the bent deflection position, as long as the spring element has not yet reached the area where it can straighten up again.
- the means for erecting the contact area comprise at least one radial recess in the Radial Flank ists Scheme of at least one functional part which is dimensioned so that the located in its elastically bent deflection position contact area can raise at the level of the recess by its elastic restoring force in its unloaded starting position.
- the recess is preferably provided adjacent to an end stop of the functional part on the side of the end stop, on which the contact area strikes the end stop in the normal irrigation mode.

- FIGS. 1 and 2a and 3b is an enlarged detail view of the device in two different operating positions, 3a to 3d a part of the device according to FIGS. 1 and 2 in different functional positions,
- FIGS. 1 and 2 are partially cutaway views of the device of FIGS. 1 and 2 in an enlarged, perspective view
- Fig. 5 is a perspective, cut-away exploded view of the device according to FIGS. 1 and 2 and
- Fig. 6 shows the device of Fig. 5 in a different perspective.
- a garden watering device is designed as a sprinkler in a functional position with an approximately vertical axis of rotation.
- the garden watering device 1 represents a so-called pop-up sprinkler.
- the sprinkler has a sprinkler head 2, which is designed as a rotatable control component in the sense of the invention.
- the sprinkler also comprises a stationary housing part 3, which is provided in an operating state with a frame for safe positioning on a substrate.
- the sprinkler head 2 forms a housing part, which has a basically known gear and at its top a water outlet nozzle.
- the transmission is a reduction gear, the rotational movement of a streamed by corresponding flow of water, fast turbine wheel in a correspondingly slower rotational movement of the control component, ie the sprinkler head 2, underpinned.
- the turbine wheel is in a basically known manner by a jet of water approximately radially flowed, which is passed through one of two spaced apart nozzle exits.
- One switching element alternately closes one of the two nozzle outlets in each case so that the water jet alternately strikes the turbine wheel through the one nozzle outlet or through the other nozzle outlet.
- the nozzle outlets are arranged at a distance from one another in such a way that, depending on the opened nozzle outlet, the rotary direction of the turbine wheel changes.
- the transmission has, on its output side remote from the turbine wheel, a planetary pinion 18 (FIGS. 4 and 5) which meshes with a stationary circumferential toothing 19 of the housing part 3.
- the switching element In order to effect a reversal of direction of the turbine wheel and consequently the sprinkler head 2, the switching element, not shown in detail, which is designed as a rocker and each one of the two nozzle exits closes, provided with a switching pin, which is approximately parallel to the axis of rotation of the sprinkler head 2 to the housing part. 3 protrudes downwards.
- the switching pin is provided at its tip with an elastically resilient contact area in the form of a spring element 6, which is shown in the figures.
- the spring element 6 is formed in the illustrated embodiment as a tightly coiled coil spring which is frictionally attached to a tip of the switching pin and thus secured and / or positively or materially connected to the tip of the contact pin.
- both collars 4, 5 are made of plastic identical to each other and in reverse mounting positions to each other and mounted relative to the sprinkler head 2 and to the housing part 3. Both collars 4, 5 are provided on the outside with a ribbing in order to allow a simple. Manual adjustment by an operator.
- Both adjusting rings 4, 5 have an inner ring, each having a toothed portion 12. The two gear portions 12 are attached during assembly to an annular locking profiling 13 together with the associated inner rings.
- the locking profiling 13 is an integral part of the housing part 3, as can be seen with reference to FIGS. 1, 5 and 6.
- the locking acting between the toothing sections 12 and the locking profiling 13 is carried out in such a way that a rotation of the adjusting rings 4, 5 in the circumferential direction is made possible manually.
- the latching but also so stable that the two adjusting rings 4, 5 remain at a rotation of the sprinkler head 2 and a stop of the switching pin and thus the spring element 6 at the end stops described below in the stationary functional position.
- Both collars 4, 5 coaxial with their inner ring each have an annular groove 15, 16, which is bounded radially outwardly by an annular web, which protrudes radially inwardly from an outer ring forming the ribbing.
- the annular groove 15, 16 has such a large width that the spring element 6 of the switching member can protrude through both annular grooves 15, 16 with little radial play when the sprinkler is fully assembled. As a result, the spring element 6 can migrate in a rotation of the sprinkler head 2 in the annulus formed by the annular groove 15, 16.
- both adjusting rings 4, 5 each have an end stop 10, 11 which protrude axially into the annular grooves and thus into the annular space.
- the spring element 6 can sweep in a rotational movement of the sprinkler head 2 within the annular groove 15, 16 before it strikes each at an end stop.
- the dimensional stability of the spring element 6 is dimensioned so that the spring element 6 remains at a stop on one of the two end stops 10, 11 in its unfolded, elongated starting position and only tilted to the other side, causing the rocker switch of the switching pivoted and the other Nozzle outlet is closed.
- the rocker switch of the switching pivoted and the other Nozzle outlet is closed.
- the end of the switching pin namely the contact area formed by the spring element 6, which comes into contact with the end stops, designed elastically yielding.
- buckling edges 9 are provided for this purpose on both sides of the spring element, which are designed as radially outwardly projecting webs. These webs correspond to guide webs 7, which protrude over the circumference of the sprinkler head 2 distributed from an inner ring radially outwards and serve to support and guide the adjusting ring 4.
- On the housing part 3 corresponding guide and support webs 8 are provided, which serve to guide and support the Unterstellringes 5.
- the webs forming the buckling edge 9 have a smaller axial height relative to the webs 7. In this case, the webs forming the folding edges 9 are made lower by approximately such an amount that corresponds to the diameter of the spring element 6.
- neither of the two end stops 10, 11 projects axially into this escape area.
- the end stops 10, 12 inevitably end with their associated ring sections on the facing edge edges of the webs 7, so that a rotation of the sprinkler head 2 is not hindered relative to the adjusting ring 4.
- the sprinkler head 2 can also be rotated beyond the corresponding end stop 10, 11 of the respective adjusting ring 4, 5 also.
- the spring element 6 remains in its bent position in the escape region below the bending edge 9. Upwards, the spring element 6 can not escape, since it is limited by the radially inwardly projecting annular web of the adjusting ring 4.
- the spring element 6 is also prevented in each case by a support edge 17 in both tilted positions, to avoid radially inwardly in the bent position.
- the spring element 6 remains in a defined buckling position, while the sprinkler head 2 is rotated beyond the corresponding end stop 10.
- the corresponding functional positions are clearly recognizable with reference to FIGS. 3a to 3d.
- FIG. 3a is the spring element 6 and also the switching member in a normal operating position.
- the spring element 6 is approximated to the end stop 10 and proposes according to FIG. 3b to this.
- the switching element is necessarily switched, so that the direction of rotation of the turbine wheel would change.
- the sprinkler head 2 is further rotated manually in the previous direction (FIG. 3 b) (FIG. 3 c)
- the spring element 6 buckles.
- the sprinkler head 2 rotates back in the direction of the end stop 10 due to the switching process that has already taken place.
- a recess 14 is provided, which is aligned radially outwardly and thereby interrupts the radially outer annular web.
- This recess 14 is sized so large that the spring element 6 through this recess 14 can sit up axially upwards. Since the sprinkler head 2 continues to move in this direction as a result of the previously occurring switching operation, the spring element 6 inevitably enters the annular groove 15 after erection.
- the spring element 6 is again in the prescribed annular space and in its predetermined pivoting range, so that the normal rotation of the sprinkler head 2 and the correspondingly set direction reversal can be resumed after a defined pivoting.
- the recess 14 is provided on the side of the end stop 10, which faces the corresponding other end stop of the other adjusting ring. This ensures that the spring element 6, regardless of the direction in which it is bent, always reappears in the pivoting area in the annular groove, which corresponds to the operational pivoting range.
- the embodiment according to FIGS. 1 to 6 also ensures that, with a proper rotation of the setting rings 4, 5, the sprinkler head 2 is rotated for setting a new pivoting angle of the sprinkler.
- the rigidity of the spring element 6 is dimensioned so large that a subsequently described overload clutch between the sprinkler head 2 and the housing part 3 is released before the spring element 6 avoids kinking.
- the overload clutch between the sprinkler head 2 and the housing part 3 can be seen with reference to FIGS. 4 to 6 and seen in principle already known.
- the overload clutch has an axially movable guide sleeve 23, on which the toothing 19 is formed, with which the planet pinion 18 of the sprinkler head 2 meshes.
- the coupling sleeve 23 ' is mounted axially and rotatably in the housing part 3.
- the coupling sleeve 23 has at its end remote from the toothing 19 end face a spur toothing 20 which engages in a corresponding latching 22 on an annular flange of the housing part 3 latching.
- the coupling sleeve 23 also superimposed in the assembled state coaxially a pin 21 which projects beyond the coupling sleeve 23 upwards.
- a coil spring 24 is slid coaxially on the pin 21, which is secured by a locking ring 25 axially on the pin 21.
- the helical spring 24 is supported axially on the upper end edge of the coupling sleeve 23 in the region of the toothing 19.
- the coupling sleeve 23 is thus pressed by the coil spring 24 down, so that the spur gear 20 is pressed against the latching 22 and the coupling sleeve 23 is secured in position.
- the pin 21 is axially supported on the latching 22 remote from the side of the annular flange of the housing part 3 from.
- the spur toothing 20 and the corresponding latching 22 are provided with corresponding tooth bevels, that the coupling sleeve 23 can be rotated at a higher torque against the pressure force of the coil spring 24.
- the spur toothing 20 and the latching 22, ie their mutually corresponding teeth disengage, as a result of which the gear coupling between the housing part 3 and the sprinkler head 2 is also canceled.
- the rigidity of the spring element 6 is so great that with proper adjustment of the adjusting rings 4, 5 disengages the overload clutch described above, as soon as one of the end stops 10, 11 strikes the spring element 6, so that the sprinkler head 2 together with the adjustment of the corresponding adjusting ring 4, 5 is twisted.
- the load limit at which the spring element 6 buckles, is thus higher than the load limit, from which the overload clutch described above is disengaged.
- the vote of the load limits is in a simple manner by appropriate coordination of the design of the Coil spring 24 on the one hand and the design and the choice of material of the spring element 6 on the other hand achievable.
