Fig. 1 shows the oblique view according to sprinkler of the present invention in the operating position with horizontal axis of rotation RA, and wherein this sprinkler can be used as rectangle sprinkler.This sprinkler comprises base body GK, and described base body can utilize first surface F1 (be coated in FIG and cover) to be erected at usually on approximate horizontal region, level land.The side of base body GK is represented by F2, and this side is contrary with first surface F1 and with described first surface at a distance of a vertical distance.

Sprinkler head RK is connected to base body GK by bracket arm TA, and can around pivot axis SA relative to base body GK pivotable.The insertion joint SK of hose coupling is arranged on base body GK.By the bracket arm TA of hose coupling SK and arrival sprinkler head RK, water is guided to described sprinkler head from water source.

Usually, sprinkler head RK comprises sprinkler transmission device RG and spray nozzle device, and the jet mode that water can be determined by described spray nozzle device is discharged by described spray nozzle device.In simple advantageous example, described spray nozzle device is made up of two portion nozzle device D1 and D2, thus, portion nozzle device D1 comprises the multiple nozzles producing rectangle sprinkler jet mode in the operating position for sprinkler shown in FIG, and Part II spray nozzle device D2 comprises the nozzle producing the second jet mode of circular sprinkler or fan spray device in the second operating position of the sprinkler shown in being configured in figure 3.Be used as in the first operating position shown in Fig. 1 of rectangle sprinkler, only Part I spray nozzle device D1 works, and is namely mounted with the water from water source.

An end (being typically designed to sprinkler transmission device) of drive assembly RG, this end connects by this way, namely, this end and bracket arm TA rotate in a rotationally fixed manner, and in the process of sprinkler operation, one end away from bracket arm TA of sprinkler transmission device relative to bracket arm around rotation RA with mode of oscillation pivotable back and forth.The boundary of oscillating pivotal motion can be regulated by adjustable ring SR usually changeably.Nozzle bracket DT is connected in a rotationally fixed manner to the end of sprinkler transmission device, and described sprinkler transmission device rotates relative to bracket arm TA and in the view of Fig. 2, is positioned at the left side of adjustable ring SR.In the example of general introduction property, the rotatable driving side of described nozzle bracket from sprinkler transmission device on the axial direction about rotation RA extends past sprinkler transmission device backward, and described nozzle bracket is rotatably supported in the fixation side of sprinkler transmission device by the support ring LR on the housing of sprinkler transmission device or on bracket arm TA, described in the view of Fig. 1, fixation side is positioned at the right of adjustable ring SR.

Bracket arm TA can rotate relative to base body GK around pivot axis SA in the pivotal orientation indicated by curved arrow together with sprinkler head RK, and after pivot axis SA pivotable 270 °, described bracket arm adopts the second operating position shown in the oblique view of Fig. 3.

In second operating position of the sprinkler in figure 3, base body can utilize second surface F2 to be erected on ground region, and described second surface is present down, and first surface F1 now upward.The rotation RA of nozzle bracket aims at vertically in this second operating position.It is vertical with level that direction in the typical construction of sprinkler on region, level ground is regarded as at this.Rotation RA is extending according in first operating position parallel with ground region of Fig. 1, and is aiming at vertically with ground region according in second operating position of Fig. 3.

In the second operating position in figure 3, only Part II spray nozzle device D2 works, namely be mounted with from water source by inserting the water of joint SK supply, wherein said Part II nozzle arrangement design is produce the jet mode being generally used for circular sprinkler or fan spray device.Be rotatably connected by the water guide between the base body GK in bracket arm TA and by the water guide pipeline in bracket arm TA, water be fed to sprinkler transmission device from insertion joint SK.Insert joint SK also to may be provided directly on bracket arm TA.

Due to bracket arm TA can together with sprinkler head RK in fig. 1 and 2 shown in two operating positions between pivotable, so same sprinkler can quickly and easily in the function of the rectangle sprinkler according to Fig. 1 and use according between the circle of Fig. 3 or the function of fan spray device.If the different jet mode being suitable for the spray nozzle device of particular spray device function is correlated with from according to Fig. 1 with Fig. 3 and according to two operating positions of the different sprinkler functions associated with described figure, then this is especially favourable.

In order to produce different jet modes, such as, the aligning of nozzle and/or the current by each nozzle or many group nozzles can be changed, or can discharge according to sprinkler function or lock each nozzle, especially also by using the outlet of protective cover covering nozzles to realize.Preferably, for each in two sprinkler functions provides independently portion nozzle device, the only portion nozzle device in described independently portion nozzle device is activated.Also can specify, be exported the device forbidden in two spray nozzle devices by covering nozzles.In a preferred embodiment, wherein comprise in two separate flow path for the nozzle bracket of each in two portion nozzle devices, and according to sprinkler function, one in two flow paths can be connected to common feed line.Thereupon, another portion nozzle device is not mounted with the water from common feed line and does not have pressure.

This advantageously realizes in the example of general introduction, the nozzle bracket DT that wherein can rotate around rotation RA can longitudinally move with axial manner relative to rotation RA in addition between two operational positions, thus, each position in two lengthwise positions is relevant to a position in two operating positions of sprinkler.For this reason, the outlet AL of radial directed can be advantageously disposed in the axial restraint position on the outlet side of sprinkler transmission device.In each position of two lengthwise positions of outlet nozzle bracket and in each position of the operating position of sprinkler, an entrance in two entrances of two separate flow path be axially positioned at this outlet AL limiting position and coordinate, to send into from the water in the outlet AL of common feed line in one of two separate flow path, and carry out dispensing water by the portion nozzle device be associated.

By user manual moving nozzle bracket DT on the axial direction of rotation RA, can switch between two portion nozzle device D1 and D2 alternately enabled.In order to avoid the adjustment of mistake, preferably specify, the switching of the portion nozzle that specifically works device and sprinkler head around pivot axis RA pivotable together with automatically occur, in this process, the portion nozzle device relevant to adopted operating position is forced to enable.

According to the general introduction example of Fig. 1 to Fig. 4, in favourable embodiment, annular groove NU is formed on nozzle bracket DT, and in the process of pivotable between two operational positions, the switching lever SS attached with bracket arm TA utilizes protuberance VS to be placed in annular groove NU.Switch the final position that lever SS is arranged in pivoting action in the specific operation position of sprinkler, and against the retainer of base body GK.Switch lever SS and relative to bracket arm TA pivotable slightly, on the axial direction relative to rotation RA, can take different positions relative to bracket arm to be engaged to from the pin in annular groove NU.

In the example according to Fig. 1, the identical retainer A1 arranged in an opposing fashion matches with the switching lever SS used with pair wise, to be pivoted in the process in the first operating position shown in Fig. 1 together with bracket arm TA at sprinkler head RK, in the final stage of this pivoting action, switch lever SS to be placed on retainer A1, but bracket arm is together with sprinkler head still further pivotable low-angle section.(switch lever SS in the process to be placed on the first retainer A1) in the process of further pivoting bracket arm TA, on the axial direction about rotation RA, nozzle bracket DT moves on bracket arm TA by switching the protuberance VS (described protuberance is engaged in annular groove NU) of lever SS.Result, as as shown according to the partial exploded view of Fig. 2, wherein for clarity, omit a part for nozzle bracket, first entrance E1 of the first flow path moves to the outlet AL of shared supply line position diametrically, so that water guide is rotatably connected and is supplied to bracket arm TA by inserting joint SK, by the first entrance E1, the water being guided to outlet AL by bracket arm TA and sprinkler transmission device RG is fed in the first flow path of nozzle bracket, and introduce Part I spray nozzle device D1, and carry out dispensing water with the first jet mode relevant to the function of rectangle sprinkler by Part I spray nozzle device.

If sprinkler head is pivoted in the second operating position shown in Fig. 3 together with bracket arm around pivot axis SA in the pivotal orientation represented by curved arrow, so the lengthwise position (this position is axially relative to rotation RA) of nozzle bracket DT is initially being kept usually, that is, Part I spray nozzle device D1 still remains the portion nozzle device worked temporarily.To the termination of the pivoting action of bracket arm, but before reaching the second final position as the pivoting action of the second operating position, switching lever SS is placed on the second retainer A2, and described second retainer is capped in figure 3 and can partly sees in FIG.Once bracket arm TA is pivoted in its second final position corresponding with the second operating position of sprinkler further, nozzle bracket DT is being pushed open from bracket arm TA about on the axial direction of rotation by the protuberance VS being engaged to the switching lever SS in annular groove NU.

Due to this movement, the second entrance E2 that axial direction about rotation RA offsets relative to the first entrance E1 moves to the outlet AL of shared supply line position diametrically on the end of nozzle bracket DT deviating from bracket arm, and by the second entrance E2 and the second flowing path P 2 of following this second entrance, the water from common feed line is fed in Part II spray nozzle device, is produced the jet mode corresponding to circular or fan spray device by the nozzle of described Part II spray nozzle device.

Fig. 5 shows the oblique view of the second embodiment according to sprinkler of the present invention, this sprinkler in the first operating position as rectangle sprinkler.In figure 6, described sprinkler is shown as in the second operating position as circular or fan spray device.In this embodiment, sprinkler head RK2 is around the angle of pivot of pivot axis SA relative to base body GK2 only pivotable 90 °.Functionally identical component have with according to the identical reference number shown in the preceding exemplary embodiment of Fig. 1 to Fig. 4.

Even according in the example of Fig. 5 and Fig. 6, by about rotation RA moving nozzle bracket DT2 in the axial direction, advantageously automatically switch between portion nozzle device D1 and D2 that specifically can enable separately.

For this reason, according in the example of Fig. 5 and Fig. 6, regulation supporting body SP is connected to sprinkler head RU2, and described body can not rotate relative to rotation RA, but can move axially.Due to the favorable friction power in the region near rotation RA, nozzle bracket DT2 is axially supported on supporting body SP, and described nozzle bracket can rotate relative to supporting body SP.By nozzle bracket DT2 being pressed on supporting body SP on the axial direction about rotation RA according to the spring FE shown in the sectional view of Fig. 8 and Fig. 9, to carry out definite location.Spring force makes the plate portion of supporting body SP press facing to the control cam KU of base body GK2.The shape of this control cam make with according to compared with in second operating position of Fig. 6, according in first operating position of Fig. 5, the distance of supporting body SP and pivot axis SA is less.Once be pivoted to the second operating position according to Fig. 6 from according to first operating position of Fig. 5, result, contrary with the restoring force of spring FE, supporting body SP and nozzle bracket DT2 therewith pushes open from bracket arm TA2 by the axial direction about rotation RA.Once back be pivoted to the first operating position according to Fig. 5 from according to second operating position of Fig. 6, spring FE back pressing nozzle bracket DT2 and described supporting body on the direction of pivot axis SA, supporting body SP has the small distance to pivot axis SA again thus, and nozzle bracket DT2 axially back moves relative to rotation RA.According in the sectional view of Fig. 8 and Fig. 9, apparently, in the second operating position in fig. 8, the second entrance E2 entering the second flowing path P 2 matches with the outlet AL of shared supply line, and water is introduced the second flowing path P 2 and is supplied to Part II spray nozzle device D2.According in first operating position of Fig. 9, lead to the outlet AL of the first entrance E1 of the first flowing path P 1 and shared supply line diametrically, and by the first entrance E1 and first flowing path P 1, water is supplied to Part I spray nozzle device D1 from common feed line, to produce the jet mode of rectangle sprinkler by described Part I spray nozzle device.

But, according in the operating position of Fig. 6 (wherein sprinkler can be used as circle or fan spray device operation), it can be desirable with admissible that sprinkler head reaches 360 ° around the rotation of rotation, corresponding in the position that operates as rectangle sprinkler according to Fig. 5, is suitable in the sprinkler head rotation during operation scope that only (such as) is 60 ° to the maximum on both sides, centre position.Described centre position is determined by the position, jet expansion direction of the nozzle of the first jet device D1 substantially in perpendicular.According in first operating position of Fig. 5, therefore what adjustable ring SR was undertaken by the mechanical stopping piece (not shown) as safety device on base body GK2 have the rotation horizontally rotated can be advantageously limited in permissible scope, and described permissible scope has the suitable angle towards both sides.

If sprinkler head pivots out from according to second operating position of Fig. 6 in the direction of the first operating position, as long as so one or two adjustable ring is arranged in the angle position that the first operating position is not allowed, the safety device do not characterized in Fig. 5 and Fig. 6 just advantageously prevents sprinkler head from taking the first operating position.User recognizes thus, and before sprinkler head can move in the first operating position by completely, first adjustable ring must rotate in tolerable angular range by he.

Fig. 7 shows the enlarged diagram alternately carrying out switching between launchable portion nozzle device at two by entrance E1, E2 of separate flow path P1, P2, thus, select the centre position between two operating positions, nozzle bracket DTZ can be vertically moved.The outlet of common feed line to be arranged on the axial direction about rotation RA and to be arranged in the axial restraint position relative to bracket arm, this outlet represented by dashed line.If nozzle bracket DT2 moves to according to the left side in the diagram of Fig. 7 relative to outlet AL (being regarded as fixing), so entrance E1 is consistent with outlet AL at the first flowing path P 1 place, and Part I spray nozzle device is mounted with the water from common feed line.On the other hand, if nozzle bracket DT2 is moved right in lengthwise position (this lengthwise position is relevant to the second operating position of sprinkler), so the second entrance E2 with share that export AL consistent, and Part II spray nozzle device to flow path P 2 and load water by second.

According to sprinkler or sprinkler head also can carry out in another way relative to operating position selected by base body and specifically enabling the favourable automatic switchover carried out between portion nozzle device.Especially, when using the switching lever of the embodiment type shown in Fig. 1 to Fig. 4, can support prejudicially relative to pivot axis SA yet and switch lever SS, this support makes to switch lever does not need retainer A1, A2.When switching lever SS relative to (bracket arm TA together with sprinkler head RK around this pivot axis) when pivot axis SA accentric support, moving pivotally in the process of having carried out, it is axial movement relative to bracket arm TA and sprinkler transmission device RG relative to rotation RA that nozzle bracket occurs.Then, do not need restrictive retainer A1 and A2 to switch, but described restricted retainer can be used as the retainer of the pivoting action for limiting bracket arm TA.

(not shown) in another embodiment, such as, by spring by nozzle bracket press-in in the farther position of the distance of pivot axis and then enter in the second operating position, and in the first operating position, by against in axial direction with bracket arm relatively supporting base body nozzle bracket changed in the position closer to pivot axis.

Feature represented in previous characteristic sum claims and the feature that can obtain from diagram can advantageously realize individually and in various combination.The invention is not restricted to described illustrative embodiments, but can change in many ways in the category of professional ability.
