Abstract

The sprinkler comprises a hollow tube 12 having a plurality of apertures 11 defined in a flat surface of the tube. A strip 2 is connected to an underside of the flat surface and supports a plurality of nozzles 21 by means of a plurality of bellows 22, each nozzle being in communication with a respective through hole in the strip. With the bellows 22 in engagement with the apertures 11, the nozzles 21 extend through the apertures 11. A guide member 3, is rotatably mounted on the hollow tube 12 and included a plurality of inclined slots 31 in which the nozzles are movably engaged. The positions of the nozzles may be adjusted by rotating the guide member. A cover 4 may be provided with flanges 42 for engaging grooves 13 in the tube 12, the cover having openings 41 in which the nozzles may be movably received. The guide member may be provided with a ring 32, and may comprise two sections each with its own ring.

Description

SPRINKLER HAVING MOVABLE NOZZLES

The present invention relates to a sprinkler including nozzles which are moved and adjusted by operating a guide member so as to obtain different sprinkling patterns.

U.S. Patent Nos. 5,645,218 and 5,51 1,727 disclose sprinklers which are involved complicated structures and their manufacturing costs are too high to be accepted in the market.

The present invention relates to sprinkler which comprises a to tubular body with a hollow tube and a plurality of apertures are defined in a flat surface of the hollow tube. An elongate strip is connected to an underside of the flat surface and has a plurality of through holes. A plurality of bellows are connected on the elongate strip and each bellow is connected to a nozzle which is in communication with one of the through holes i5 corresponding thereto. The nozzles extend through the apertures and the bellows are engaged with the apertures respectively. A guide member is rotatably mounted to the hollow tube and includes a plurality of inclined slots in which the nozzles are movably engaged.

The present invention will become more obvious from the go following description when taken in connection with the accompanying drawings, in which: Fig. I is an exploded view to show the sprinkler of the present invention; Fig. 2 is a cross sectional view of the sprinkler; Fig. 3 is an enlarged view to show the connection of a nozzle and a hollow tube, a guide member and a top cover of the sprinkler; Fig. 4 shows that the nozzles are adjusted by the inclined slots of the guide member; Figs. 5 to 7 shows different patterns of sprinkling; and Fig. 8 shows another embodiment of the guide member.

Referring to Figs. I to 3, the sprinkler of the present invention comprises a tubular body 1 with a hollow tube 12 and a plurality of apertures 11 are defined in a flat surface of the hollow tube 12. Two JO grooves 13 are defined in an outer periphery of the hollow tube 12 for connecting a top cover 4 which will be described hereinafter. An elongate strip 2 is connected to an underside of the flat surface of the hollow tube 12 and has a plurality of through holes 23 defined therethrough. A plurality of bellows 22 are connected on the elongate strip 2 and each bellow 22 is i5 connected to a nozzle 21 which is in communication with one of the through holes 23 corresponding thereto. A plurality of annular sealing flanges 25 extend from the elongate strip 2 and each bellow 22 is enclosed by one of the sealing flanges 25 so as to prevent leakage. The nozzles 21 extend through the apertures 11 and the bellows 22 are engaged with the o apertures 11 respectively. A plurality of guide stubs 24 extend from an inner periphery of each of the through holes 23 so as to reduce turbulence when the water enters the through holes 23.

A guide member 3 includes a plate with a semi-circular cross section and a ring 32 is connected to an end of the plate. The ring 32 is rotatably mounted to the hollow tube 12 of the body I and the plate includes a plurality of inclined slots 31 defined therethrough. The nozzles 21 are movably engaged with the inclined slots 31. Therefore, the directions of the nozzles 21 can be adjusted by rotating the guide member 3.

The top cover 4 has two side flanges 42 which are engaged with the grooves 13 and the top cover 4 includes a plurality of openings 41 in which the nozzles 21 are movably received.

As shown in Fig. 4, the nozzles 21 are moved by the inner periphery defining the inclined slots 31 when the guide member 3 is rotated such that the directions of the nozzles 21 can be adjusted and different o patterns of sprinkling can be obtained as shown in Figs. 5 to 7.

Fig. 8 shows that the guide member can be made to be composed of two sections 3a and 3b so that the total number of the inclined slots 31 can be more than the previous embodiment, Each of the sections 3a and 3b has its own rings 32a/32b located a first end thereof, the two respective second ends of the sections 3a and 3b are connected with each other to form a longer guide member.

While the embodiment has been shown and described in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the o scope of the claims.

Claims

CLAIMS: 1. A sprinkler comprising: a tubular body with a hollow tube and a

plurality of apertures defined in a flat surface of the hollow tube; an elongate strip connected to an underside of the flat surface of the hollow tube and having a plurality of through holes defined therethrough, a plurality of bellows being connected on the elongate strip and each bellow being connected to a nozzle which is in communication 0 with one of the through holes corresponding thereto, the nozzles extending through the apertures and the bellows being engaged with the apertures respectively, and a guide member rotatably mounted to the hollow tube and including a plurality of inclined slots defined therethrough, the nozzles being movably engaged with the inclined slots.
2. The sprinkler as claimed in claim 1, wherein the hollow tube of the body includes grooves defined in an outer periphery thereof and the sprinkler includes a top cover having two side flanges which are engaged with the grooves, the top cover including a plurality openings in which the so nozzles are movably received.
3. The sprinkler as claimed in claim 1 or 2, wherein the guide member includes a plate with a semi-circular cross section and a ring is connected to an end of the plate, the inclined slots being defined through the plate and the ring is rotatably mounted to the hollow tube of the body.
4. The sprinkler as claimed in claim 1, 2 or 3, further comprising a plurality of guide stubs extending from an inner periphery of each of the through holes.
