Description

DEVICE FOR MOUNTAING A FLAT

The invention relates to a device for sprinkling a surface, in particular a turf surface, wherein the device comprises a carrier device, a liquid distribution device with a plurality of nozzles held thereon and a shielding device with at least one shielding element for shielding liquid streams which have leaked from at least a part of the nozzles.

Such devices are known, e.g. in the form of so-called lawn sprinklers, in which a user can shield liquid streams escaping from a part of the nozzles by means of an attachable shielding device. When commissioning the device settings are usually to make, for example, to determine the size and contour of the surface to be wetted, the so-called "sprinkler image". The shielding means shielding the liquid streams serves the user not to be charged with the liquid during the adjustment operation. For this purpose, the leaked from at least a portion of the nozzle liquid streams are shielded by the shielding device is placed on the liquid sigkeitsverteilungseinrichtung. After adjustment, the shield can be removed again.

Object of the present invention is to develop a generic device such that it can be handled in a user-friendly manner. This object is achieved in a device of the type mentioned in the present invention, that the shielding device is movably held on the device, wherein the at least one shielding element from a release position in a shielding position and back is feasible, wherein in the release position from the nozzles each leaked liquid streams are released and wherein in the shielding the leaked from at least a portion of the nozzle liquid streams are shielded at least in one direction.

In the device according to the invention, the at least one shielding element can be transferred from a release position into a shielding position and vice versa. For example, a user can transfer the at least one shielding element into the shielding position when the device is put into operation. Liquid streams exiting from at least part of the nozzles can be shielded by means of the at least one shielding element at least in one direction, for example vertically upwards or also in the direction from one side of the device. Meanwhile, a user may e.g. Adjust the irrigation image of the device or position the device as a whole on the surface to be covered, with virtually no risk of undesirable liquid application to the user. If the user has made the desired adjustments to the device, he can transfer the at least one shielding element from the shielding position into the release position, in which the liquid streams leaked from the nozzles are released and the actual irrigation operation of the device can be accommodated.

The shielding device is held movably on the device. By the movable mounting of the shielding device and in particular its at least one shielding element on the device can be ensured that the shielding device is not undesirably removed from the device. In this way, it can not be misplaced or, in the worst case, even completely lost. The user is spared thereby, when transferring the at least one shielding element from the release position into the shielding position and vice versa to pay attention to its whereabouts, so that the device according to the invention can be handled in a user-friendly manner for the user.

It is advantageous if in the shielding position at least liquid streams of those nozzles can be shielded, which are aligned in the direction of an operating and / or adjusting device encompassed by the device. As already mentioned, the commissioning of the device usually requires actions of the user, which he undertakes, for example, at the operating and / or adjusting device. By shielding that part of the nozzles, which are aligned in the direction of the operating and / or adjusting device, the risk is further reduced that the user is undesirably exposed to the liquid during adjustment.

Preferably, the device comprises an operating and / or adjusting device which has operating and / or adjusting elements which are arranged at least predominantly on one side of the device. The risk that the user is undesirably exposed to the liquid when setting the device during startup, can be further reduced in this way. For the concentration of at least a part of the operating and / or adjusting elements on one side of the device requires actions of the user predominantly on the same side of the device. It is advantageous if the at least one shielding element in the shielding position covers those nozzles whose liquid flows can be shielded. This provides a structurally simple way to shield the leaked liquid streams from these nozzles. The liquid streams can impinge on the at least one shielding element from below and be diverted therefrom.

Preferably, the at least one shielding element protrudes in the shielding position, based on a plan view of the same, at least partially laterally beyond those nozzles, the liquid streams are shielded. In this way, an effective shielding of the liquid flows can be ensured.

In a structurally simple embodiment and compact construction of the device, the at least one shielding element is advantageously at least partially plate-shaped or strip-shaped. The at least one shielding element may e.g. cover those nozzles whose liquid streams are shieldable. The plate-like or strip-like configuration of the at least one shielding element includes a non-planar configuration thereof. Thus, the at least one shielding element may be formed, for example, curved or arched.

It is advantageous if the at least one shielding element, based on the nozzles whose fluid streams are shieldable, is at least partially convex. As a result, the at least one shielding element has a surface which faces the nozzles and, with respect thereto, has a convexly curved surface onto which the liquid streams to be screened can impinge. Due to the convex shape, the liquid is deflected. For example, the liquid may be in particular when the at least one shielding element, the nozzles, as explained above, to be deflected in the direction of the area to be wetted. This can provide effective shielding and further reduce the risk of the user being exposed to the fluid.

Advantageously, the at least one shielding element is movably mounted on the device. Due to the movable mounting on the device, a structurally simple possibility is given to transfer the at least one shielding element in a user-friendly manner from the release position into the shielding position and vice versa.

It can be provided that the at least one shielding element is movably mounted directly on the carrier device or indirectly, for. B. when it is movably mounted on the liquid distribution device, which in turn is held on the support means.

It is particularly advantageous if the at least one shielding element is pivotably mounted on the device. It has been shown in practice that the transferability of the at least one shielding element from the release position into the shielding position and vice versa can thereby be implemented in a technically particularly simple manner.

In other developments of the device according to the invention can be provided that the at least one shield is slidably or rotatably mounted on the device. A combination of a sliding, a pivotable and / or a rotatable mounting is possible. The shielding device preferably comprises at least one first bearing element connected to the at least one shielding element, for which at least one second bearing element arranged on the device defines a guide. By means of the guide, a movement of the at least one first bearing element and thus also of the at least one shielding element can be guided relative to the device. The uniformity of the movement and the correctness of the direction of movement of the at least one shielding element can be ensured in a simple manner.

Preferably, the device has at least one locking device for locking the at least one shielding element in the release position and / or in the shielding position. This can ensure that the at least one shielding element is not undesirably removed from the release position and / or the shielding position. If the at least one shielding element can be locked in the shielding position, reliable shielding of the fluid streams can be ensured.

Conveniently, the at least one locking device is designed as a latching device and / or as a clamping device, because this allows a simple structural design of the at least one locking device and easy handling of the shielding device.

It can be provided that the at least one shielding element can be locked to the carrier device and / or to the liquid distribution device. In order to configure the at least one locking device, it is accordingly possible to apply to the at least one shielding element as well as to the carrier device and / or the liquid distribution device. other assigned and cooperating locking elements and / or clamping elements can be arranged.

It is advantageous if the device has an actuating device with at least one actuating element for transferring the at least one shielding element from the release position into the shielding position and / or vice versa. By means of the at least one actuating element, the at least one shielding element can be transferred in a user-friendly manner from the release position into the shielding position and / or vice versa.

It is advantageous if the at least one actuating element is designed as an actuating lever arranged on the shielding device or encompassed by the shielding device. The actuator can be designed constructively simple in this way.

Preferably, the liquid distribution device is movably mounted on the carrier device. Due to the movable mounting of the liquid distribution device, the nozzles can be moved relative to the carrier device. Depending on how far the preferably adjustable range of motion of the nozzles is relative to the carrier device, for example, a different irrigation pattern can be achieved with the device. The device is thus more versatile. Due to the bearing on the carrier device, the liquid distribution device can be moved relative to this in a reliable manner, so that a constant irrigation of the area to be wetted can be ensured.

The device for movably supporting the liquid distribution device preferably comprises at least one bearing element, which also holds the min. at least one shielding element is supported on the device. This bearing element thus fulfills two functions: On the one hand, it serves for the storage of the liquid distribution device on the device. On the other hand, it serves to support the at least one shielding element on the device. This can, as already explained, be movably mounted on the carrier device or on the liquid distribution device. In this way, a compact design of the device can be achieved.

Conveniently, the liquid distribution device is pivotally mounted on the support means about a horizontal axis, along or parallel to which the nozzles are arranged. In this way, the device can form a so-called "rectangular sprinkler", in which by pivoting the liquid distribution device about the horizontal axis on the surface to be wetted a rectangular sprinkler image can be achieved. The individual nozzles are preferably oriented transversely to the axis, wherein they may be aligned in particular at different angles relative to the axis.

Alternatively or additionally to the embodiment described above, it can be provided that the liquid distribution device is pivotable about a vertical axis. In this way, the device can form a so-called "segment or circular sprinkler" with which a sprinkling image on the surface to be frosted is obtained, e.g. can be achieved in the form of a circle or a circle segment.

It is advantageous if the liquid distribution device is designed to be pivotable relative to the at least one shielding element. For example, this can be done in a structurally simple manner by virtue of the fact that the liquid distribution device can be pivoted relative to the carrier device and the at least one shielding element can be locked relative to the carrier device. For locking, for example, the locking device described above can be used.

Advantageously, the liquid distribution device is pivotable relative to the screening position engaging at least one shielding element between a first end position and a second end position, wherein in the first end position and / or in the second end position, the number of those nozzles whose liquid streams are shielded, is less than the number those nozzles whose liquid streams are shielded when the liquid distribution device occupies an intermediate position between the first end position and the second end position during pivoting. If the at least one shielding element occupies the shielding position, in this way the liquid distribution device can be pivoted relative to it such that at least in the first end position and / or at least in the second end position liquid flows are not shielded, which are then shielded when the liquid distribution device is shielded. an intermediate position. In particular, it can be provided that in the first and / or second end position of the liquid distribution device no liquid streams are shielded, ie, in the first and / or second end position, the liquid streams can pass laterally through the at least one shielding element, in an intermediate position of the liquid distribution device however, liquid streams leaked from at least part of the nozzles would be shielded. In this case, "intermediate position" is not to be understood as meaning that in this embodiment the liquid distribution device could occupy only discrete individual positions. "Intermediate position" denotes any possible relative position of the liquid distribution device and of the at least one shielding element during pivoting from the first end position into the second end position. Position and vice versa. In this embodiment, when adjusting the irrigation image of the device, a user can also use the liquid streams of those nozzles which are shielded in the intermediate position. Namely, if the liquid distribution device is in the first or second end position, the liquid streams are also released from the aforementioned nozzles, so that the user can recognize where the liquid streams emerging from these nozzles impinge on the surface to be wetted. This facilitates the setting of the area to be kissed.

A preferred embodiment of a device according to the invention for sprinkling a surface is shown in perspective in Figures 1 and 2. The device is designed as a so-called "lawn sprinkler", which contrary to its name can be used not only for sprinkling lawns but also for sprinkling areas that are planted with vegetation other than grasses, such as flowerbeds. For this reason, the lawn sprinkler is referred to below as designated by the reference numeral 10 Sprenger.

The sprinkler 10 comprises a carrier device 12 having a first carrier part 16 arranged on its front side 14 and a second carrier part 20 arranged on its rear side 18. The first carrier part 16 and the second carrier part 20 are connected to one another by two connecting elements in the form of struts 22 and 24 , On the carrier device 12, a liquid distribution device 26, a transmission device 28 and a connection device 30 are held. To the held on the back 18 on the second support member 20 connecting device 30 can be connected in a known and therefore unspecified manner, a liquid supply line, for example, a water hose. In this way, the liquid distribution device 26 in a likewise known and therefore unspecified manner through the connection device 30 and the transmission device 28 through a liquid to be distributed, in particular water, are supplied.

The liquid distribution device 26 comprises an elongated bar-shaped nozzle body 34 aligned along an axis 32 of the sprinkler 10. The latter receives a multiplicity of nozzles 36, which are aligned in two rows parallel to the axis 32. From the nozzles 36, liquid supplied to the sprinkler 10 via the connection device 30 can escape and be distributed on the surface to be wetted. For reasons of clarity, only one selection of the nozzles 36 in the drawing is provided by way of example with reference numerals and associated reference lines.

At its end face facing the first support part 16, the nozzle body 34 has a bearing element 38, which passes through the first support part 16 in the axial direction and cooperates there with a connecting element in the form of a screw 40, so that the nozzle body 34 on the first support part 16 is held (Figure 3). The bearing pin 38 engages in a not shown in the drawing corresponding receptacle on the first support member 16 a. The bearing of the nozzle body 34 on the first carrier part 16 is such that the nozzle body 34 relative to the first carrier part 16 and thus relative to the support means 12 is pivotable about the axis 32 as a whole.

On its end face facing the gear mechanism 28 and the second carrier part 20, the nozzle body 34 is connected to the gear device 28 in a known and unspecified manner, which in turn is pivotably mounted on the second carrier part 20 in a likewise known and therefore unspecified manner. In this way, the nozzle body 34 can be pivoted together with the transmission device 28 about the axis 32. The nozzle body 34 can be pivoted from a first end position, which can be predetermined by a first adjusting element 42 of the transmission device 28, to a second end position, which can be predetermined by a second adjusting element 44 of the transmission device 28.

The transmission device 28 and the connection device 30 with which the amount of liquid supplied to the sprinkler 10 can be regulated thus form operating and / or adjusting devices of the sprinkler 10.

By means of the adjusting elements 42 and 44, it is possible to predetermine angles which the nozzle body 34 can assume in the first end position or the second end position relative to the surface to be covered, on which the sprinkler 10 is placed. Due to the design of the nozzle body 34 with the aligned parallel to the axis 32 nozzles 36 which are tilted relative to this at different angles, resulting in the use of the sprinkler 10 a rectangular-shaped irrigation image. Therefore, the sprinkler 10 is also called a "rectangular sprinkler". As discussed below, if desired, to shield fluid streams that have exited a portion of the nozzles 36, the sprinkler 10 includes a shield 46. The shielding device 46 is formed elongated, wherein it has a length adapted to the nozzle body 34. It comprises a shielding element 48, which is designed in the form of a slightly curved plate 50. The length of the plate 50 in the axial direction is dimensioned such that, in the position of the shielding device 46 shown in FIG. 2, which will be explained below, approximately 60% of the nozzles 36 are able to overlap, starting from the end of the gearbox 28 which faces the gear mechanism 28 Nozzle body 34.

Based on the nozzles 36, the plate 50 is convex. Transversely to the axis 32, it is dimensioned so that it slightly overlaps the nozzle body 34 in its width. Starting from a central portion 52, it faces the nozzle body 34 angled side portions 54 and 56, which form their, relative to the nozzles 36, convex shape even more clearly.

In the axial direction go from the side portions 54 and 56 webs 58 and 60, at the first support member 16 end facing a first holding part 62 of the shielding 46 is held. The first holding part 62 connects the webs 58 and 60 with each other, so that between the first holding part 62 and the central portion 52 of the plate 50, a through hole 64 of the shielding device 46 is formed.

By means of the first holding part 62, which is arranged in the axial direction between the first carrier part 16 and the front end of the nozzle body 34 facing it, the shielding device 46 is held on the carrier device 12. A central and not shown in the drawing opening of the first holding part 62 is in the axial direction of the bearing pin 38th passed through, so that the first holding part 62 and thus the shielding device 46 is held on the liquid distribution device 26 and thus indirectly on the first support member 16.

Similarly, the shielding device 46 is held on its side facing the transmission device 28 by means of a second holding part 66 in a manner not shown in the connecting region between the nozzle body 34 and the transmission device 28. The second holding part 66 connected to the plate 50 engages in a gap between the nozzle body 34 and the transmission device 28. It is held between them in such a way that the shielding device 46 and thus the plate 50 can pivot about the axis 32.

The bearing pin 38 serves both for the movable mounting of the nozzle body 34 about the axis 32 on the first support member 16 and for the movable mounting of the shielding 46 on the liquid distribution device 26 about the same axis 32. Its surface defines a guide for the first holding part 62 for a reliable Swiveling the shielding 46 about the axis 32nd

In the ordinary operation of the sprinkler 10, the shield 46 and thus the plate 50 is pivoted about the axis 32 so that the plate 50 is disposed below the nozzle body 34, being approximately between the struts 22 and 24. This is shown in FIG. 1 and FIG. 4A, which illustrates the sprinkler 10 in operation with a liquid supply line connected to the connection device 30 in the form of a hose 81. From the nozzles 36 leaked fluid streams 68 are released, ie they can act on the surface to be wetted. The nozzle body 34 may be sprinkled about the axis 32 relative to the support means 12 be pivoted between the first end position and the second end position. This position, in which the liquid streams 68 are released, is referred to as the release position of the shielding device 46 and thus of the plate 50. For reasons of clarity, only one selection of the liquid flows 68 in the drawing is provided by way of example with reference numerals and associated reference lines.

Based on the release position, the shielding device 46 and thus the plate 50 can be transferred to a position in which the leaked liquid streams 68 are partially shielded. For this purpose, the user can for example attack directly on the shielding device 46 in order to pivot about the axis 32. He can also operate an actuator 70 of the sprinkler 10 with an actuating element 72 in the form of a protruding from the first holding part 62 operating lever 74. This has relative to the axis 32 on a lateral offset. When the actuating lever 74 is acted upon by the user, this allows pivoting of the shielding device 46 about the axis 32, so that it can assume the position already referred to in FIG. 2 and in FIG. 4B.

The pivoting can, for example, take place until a latching element arranged on the first holding part 62 in the form of a latching receptacle 76 engages with a latching element arranged on the first carrier part 16 in the form of a latching projection 78 projecting in the direction of the first holding part 62. The latching device formed in this way by the latching receptacle 76 and the latching projection 78 forms a locking device 80 of the blaster 10. Are the shielding device 46 and thus the plate 50 is locked relative to the first support member 16, the shielding device 46 assumes a position which is symmetrical to a perpendicular to a footprint for the sprinkler 10 oriented plane in which the axis 32 extends. In this position, the plate 50, as already mentioned, cover a part of the nozzles 36 according to their dimension. From the nozzles 36 leaked fluid streams 68 are shielded when pivoting about the axis 32 by means of the plate 50, depending on the position of the nozzle body 34, ie they can impinge on the plate 50 from below. For this reason, this position of the shielding device 46 and thus of the plate 50 is referred to as a shielding position.

The shielded liquid streams 68 are due to the convex shape of the plate 50 via the side portions 54 and 56 down to the surface to berleitende derived. In contrast, in the shielding position, liquid streams 68 from nozzles 36, which the nozzle body 34 has on its side facing the first carrier part 16, are not shielded by means of the plate 50, because they are arranged below the through-opening 64. The leaked from these nozzles 36 fluid streams 68 pass through the passage opening 64 and can irrigate the surface to be wetted.

At startup, the sprinkler 10 may be placed by a user on the surface to be frosted and the plate 50 transferred to the shielding position. After connecting the hose 81 to the connecting device 30 and supplying liquid, the surface to be wetted is sprinkled with liquid streams 68 from those nozzles 36 which are not covered by the plate 50 but are arranged below the through-opening 64. This allows the user to set the sprinkler image of the sprinkler 10 at start-up. For example, the user can regulate the amount of liquid supplied to the connection device 30 and / or predetermine the first end position and the second end position of the nozzle body 34 when pivoting about the axis 32 by means of the adjustment elements 42 and 44. The desired position and orientation of the sprinkler 10 on the surface can also be selected. It may further be provided that individual nozzles 36 are switched on or off by the user.

The user preferably makes these settings behind the sprinkler 10, i. in its imaginary extension beyond the rear side 18 along the axis 32. The arranged in the shielding below the plate 50 nozzles whose fluid streams 68 are shielded are predominantly tilted relative to the axis 32 so that they towards the back 18 of the sprinkler 10th are aligned. In any case, the liquid streams 68 which have escaped from them are partially shielded by the plate 50, so that the user behind the sprinkler 10 is not exposed to the liquid during the setting process.

Depending on which first end position and which second end position of the nozzle body 34 the user has predetermined by means of the adjusting elements 42 and 44, it may be possible that when pivoting the nozzle body 34 about the axis 32 is not covered by all of the plate 50 in the shielding Nozzles 36 leaked fluid streams 68 are permanently shielded by means of the plate 50.

It is first assumed that the nozzle body 34 occupies a position in which its upper side, on which the nozzles 36 are arranged, relative to a plane 82 which is parallel to one of the underside of the sprinkler 10th defined plane and containing the axis 32, does not include an angle (Figure 5A). In this case, it is possible by means of the plate 50 to shield both a first liquid stream 86, which has emerged from a first nozzle 84, shown by way of example, and a second liquid stream 90, which has emerged from a second nozzle 88 shown by way of example. The nozzles 84 and 88 exemplify the nozzles 36 covered by the plate 50.

If the nozzle body 34 assumes the first end position, its upper side encloses a first pivot angle 92 with the plane 82 (FIG. 5B). In the present case, the first pivoting angle 92 is so great that the first liquid stream 86 of the first nozzle 84 can be shielded by means of the plate 50, but not the second liquid stream 90 of the second nozzle 88, because this can pass the plate 50 below the side portion 56.

In a corresponding manner, the nozzle body 34 can assume the second end position in which its upper side encloses a second pivot angle 94 with the plane 82 (FIG. 5C). In the present case, the second pivot angle 94 is so great that the second fluid stream 90 of the second nozzle 88 can be shielded by means of the plate 50, but not the first fluid stream 86 of the first nozzle 84 because it can pass the plate 50 below the side portion 54.

This means that, at least in the first end position and in the second end position of the nozzle body 34, the second liquid stream 90 or the first liquid stream 86 can also be used in the shielding position of the plate 50 for sprinkling the surface to be wetted. In this way, the user can also control the range of the liquid streams 86 and 90 during start-up and adjustment of the sprinkler 10. It can also be provided that the two nozzles 84 and 86 are arranged at such a distance and an orientation relative to one another that in the first and / or the second end position of the nozzle body 34, both liquid streams 86 and 90 can pass the plate 50 laterally, although this assumes its shielding setting, whereas the liquid streams 86 and 90 are shielded from the plate 50 in the intermediate position of the nozzle body 34 shown in Figure 5A.

In addition, it may be provided that the nozzle body 34 comprises only a single row of nozzles, wherein leaked from at least a portion of the nozzle liquid streams are shielded in the intermediate position of the nozzle body 34, whereas the liquid streams of all the nozzles in the first and / or second end position of the nozzle body the plate 50 can pass laterally.

When commissioning and adjusting the sprinkler 10, in the case of the end positions of the nozzle body 34 considered in the present case, a rectangular sprinkling image 96 with a recess 98 behind the sprinkler 10 results (FIG. 6). If the user is in setting the sprinkler 10 within the recess 98, he will not be acted upon by leaking from the nozzle 36 liquid.

After adjusting the sprinkler 10, the user may transfer the shield 46 from the shielding position to the release position where all of the liquid streams 68 emanating from the nozzles 36 are released to irrigate the surface as desired. An advantage of the sprinkler 10 is that the shielding device 46 is held on the support means 12 not only when the plate 50 assumes its release position and / or its shielding position, but also during the transfer from the release position to the shielding position and vice versa. In this way it can be ensured that the shielding device 46 is not inadvertently removed from the sprinkler 10 by a user and thereby misplaced or, in the worst case, even completely lost.
