Description

DESCRIPTION OF THE DRAWINGS

[0022] In order to complement the description being made and with the object of helping to better understand the characteristics of the invention, in accordance with a preferred practical embodiment thereof, said description is accompanied, as an integral part thereof, by a set of drawings where, in an illustrative and non-limiting manner, the following has been represented:

[0023] FIG. 1 shows a profile view of the oscillating rotation sprinkler.

[0024] FIG. 2 shows a cross-sectional view of the oscillating rotation sprinkler.

[0025] FIG. 3 shows an exploded view of the oscillating rotation sprinkler.

PREFERRED EMBODIMENT OF THE INVENTION

[0026] What follows is a description, with the help of FIGS. 1 to 3, of an exemplary embodiment of the invention.

[0027] FIG. 1 shows the oscillating rotation sprinkler in a perspective view. As can be seen in the figure, the sprinkler of the invention is configured to be mounted on drainpipes, such that the sprinkler nozzle is facing the terrain.

[0028] FIG. 2 shows the oscillating rotation sprinkler in a cross-sectional view that allows the relationship and position between the different elements of the oscillating rotation sprinkler to be viewed.

[0029] Likewise, FIG. 3 shows the different elements that make up the sprinkler in an exploded view. More specifically, the sprinkler must comprise at least: [0030] a nozzle (4) which controls the passage of water and allows the water that circulates through the drainpipes to leave towards the outside; [0031] an inner body (5) on which the nozzle (4) is mounted; [0032] a plate holder (1) arranged around the inner body (5); and [0033] a deflector plate (2) which is joined to one end of the plate holder (1) and which comprises a plurality of channels (7) that receive and direct the water coming out of the nozzle (4).

[0034] As can be seen in FIG. 2, the inner body (5) is preferably of a hollow cylindrical configuration. The water coming out of the nozzle (4) passes through said inner body (5) to the deflector plate (2). In the exemplary embodiment shown in FIG. 3, the upper end of the inner body (5) comprises slots (9), which divide the upper end into upper sections (10) configured to be introduced in a plurality of through holes (11) present on the nozzle (4). This way the nozzle (4) and the inner body (5) are linked.

[0035] The sprinkler may also comprise a base connector (3) configured to allow for the connection of the nozzle (4) to the drainpipes through which the water reaches the sprinkler. Preferably, said base connector (3) is joined to the inner body (5), as observed in FIG. 2, by means of a thread in correspondence with the upper end of the inner body (5).

[0036] The plate holder (1) has an upper section (14) in which there is at least one opening (12), shown in FIG. 3, through which the inner body (5) is arranged, and has a plurality of support columns (13), also shown in FIG. 3, which come out of said upper section (14) and which are configured to be joined by the upper end thereof to the deflector plate (2).

[0037] The key of the oscillating rotation sprinkler described is that it comprises a warped ring (8) which is arranged between the inner body (5) and the plate holder (1) and which has a warped configuration. Said warped ring (8) can also be seen in FIG. 3.

[0038] More specifically, as shown in FIG. 2, the inner body (5) comprises an outer perimeter projection (15) arranged on the lower end thereof. The warped ring (8) is arranged, as shown in FIG. 2, around the inner body (5) in the space confined between the upper section (14) of the plate holder (1) and the outer perimeter projection (15) of the inner body (5).

[0039] As seen in the example in FIG. 1, the warped ring (8) causes the deflector plate (2) to have an unstable equilibrium. This way, when the water starts coming out of the nozzle (4) and collides with the deflector plate (2), the deflector plate (2) begins to oscillate. This oscillating movement is maintained the entire time the sprinkler is functioning.

[0040] Another element the sprinkler may comprise is a stop (6) as shown in the figures, such as in FIG. 3, which prevents the plate holder (1) and the warped ring (8) from coming out of their assembled position. The stop (6) has a diameter, which is similar to that of the perimeter projection (15) of the inner body (5) and limits the degree of oscillation of the plate holder (1).

[0041] The plate holder (1) and the warped ring (8) are not joined. Both are trapped between the perimeter projection of the inner body (5) and the stop (6). If the latter is disassembled, it is necessary to disassemble the deflector plate (2) of the plate holder (1) to be able to remove it and be able to then remove the warped ring (8).

[0042] Preferably, the stop (6) is mounted on the inner body (5) by means of three slots and on which the nozzle (4) is supported. Both pieces are fixed by the threaded joint between the base connector (3) and the inner body (5) as shown in FIG. 2.
