Description

TECHNICAL FIELD

The present disclosure relates to a sprinkler and more particularly to a single or dual sided direction-controllable sprinkler.

BACKGROUND

Conventional sprinklers employ a single trigger switch to control the directions of sprinkling of a sprinkler, such as disclosed in U.S. Patent No. 7,607,590 . In U.S. Patent No. 7,909,266 , two trigger switches are employed to control the directions of sprinkling of sprinklers on two sides. The upward or outward sprinkling direction of the sprinkler is controlled by the triggering of the trigger switches.
However, the trigger switch of conventional sprinklers only allows triggering in a single way. The single trigger switch can only control to sprinkle outwardly or upwardly. As for the two trigger switches, it needs to trigger two times to achieve the same effect if the sprinkling directions on the two sides are the same. It is inconvenient to use.

SUMMARY

A single or dual sided direction-controllable sprinkler according to the present invention is set out in claim 1.
The present invention will become more fully understood by reference to the following detailed description thereof when read in conjunction with the attached drawings.

DETAILED DESCRIPTION

Please refer to Fig. 1. Fig. 1 is an exploded perspective view of a preferred embodiment of a single or dual sided direction-controllable sprinkler of the present invention. The single or dual sided direction-controllable sprinkler mainly comprises a base 10, a main body 20, two trigger portions 30, two fasteners 40 and a cover 50.
The base 10 is disposed with a combination seat 11.
The main body 20 is pivotally disposed on the combination seat 11. An accommodation chamber 21 is disposed inside the main body 20. A water inlet 22 is disposed on a side of the accommodation chamber 21, and a plurality of water outlets 23 is disposed on a top of the accommodation chamber 21. In an embodiment, the accommodation chamber 21 is a hollow tube configured for connection to a water source and the water outlets 23 are a plurality of nozzles in fluid communication with the tube.
The two rotational trigger portions 30 are slidably disposed on the main body 10. A plurality of slant guiding openings 31 corresponding to the water outlets 23 is disposed on the trigger portions 30. The water outlets 23 go through the guiding openings 31. The slant angles of the water outlets 23 are changed by positions of the guiding openings 31. A trigger protrusion 32 is protruded from each of two sides of each of the trigger portions 30. The trigger protrusion 32 comprises an arm 321 and a connecting section 322. The arm 321 is roughly perpendicular to the main body 10. The connecting section 322 is extended from a free end of the arm 321 towards the other arm 321 so that the two connecting sections 322 are disposed close to each other. When the trigger portions 30 are positioned in a same way, positions of the two connecting sections 322 are also in a same way. The connecting section 322 of one of the two trigger portions 30 has a slide rail 323. In an embodiment, the trigger portions 30 comprise a pair of guides disposed on the main body and having a plurality of angled guide openings through which the nozzles extend for adjusting the angles of the nozzles. In this embodiment, the guides are independently rotatable relative to the main body and each of the guides has a trigger protrusion extending from it. The trigger protrusion of one of the guides is configured for selectively engaging the trigger protrusion of the other of the guides in a mating relationship.
Please refer to Fig. 2. Fig. 2 is a sectional view of the fastener and the trigger protrusion of the preferred embodiment of the single or dual sided direction-controllable sprinkler of the present invention. The fastener 40 has a groove 41, and a limitation piece 42 is protrudingly disposed inside the groove 41. The limitation piece 42 is slidably and limitedly disposed on the slide rail 323 of the connecting section 322 in order to allow the fastener 40 to slide on the connecting section 322. The fasteners 40 are selectively fixed with the other trigger protrusion 32 so that the two trigger protrusions 32 are coupled or separated. An area of the groove 41 is close to that of the connecting section 322. The other connecting section 322 can also be securely and limitedly connected with the groove 41. In an embodiment, the fastener 40 is configured for selectively securing the trigger protrusions in the mating relationship such that the guides have the same rotatable position when the trigger protrusions are secured in the mating relationship by the fastener and are independently controllable when the trigger protrusions are not secured in the mating relationship by the fastener.
The cover 50 is disposed with a plurality of direction guiding holes 51. The water outlets 23 go through the direction guiding holes 51. The positions of the water outlets 23 are changed along the longitudinal shape of the direction guiding holes 51.
In order to further explain the structures and characteristics of the present invention, as well as the technical means and expected effects; the ways of usage are specifically described hereunder for in-depth understanding.
Please refer to Figs. 3A to 3D and 4A to 4D. When the fasteners 40 are not connected with the two closely disposed connecting sections 322, the two trigger portions 30 are operated separately for adjusting sprinkling positions. The trigger portions 30 are facing outward or upward at the same time; or one of the trigger portions 30 is facing upward, while the other trigger portion 30 is facing outward. Each of the trigger portions 30 is adjusted individually. Therefore, four different sprinkling combinations are available to meet different requirements and needs.
When the two trigger portions 30 are needed to connect together, set the two trigger portions 30 at a same sprinkling position, and move the fasteners 40 along the slide rail 323 so that the other connecting section 322 is guided inside the groove 41. The two closely disposed connecting sections 322 are limited and fixed by the fastener 40. Because the area of the groove 41 is close to that of the connecting section 322, the fastener 40 is securely disposed on the connecting section 322 and does not detach from each other after the fastener 40 is connected with the other connecting section 322. After the connecting section 322 is limited by the fastener 40, the two trigger portions 30 have the same sprinkling position. Please refer to Figs. 5A, 5B, 6A and 6B. The trigger portions 30 are facing upward or outward at the same time. When the same sprinkling direction of the two trigger portions 30 is required, simply adjust one of the two trigger protrusions 32 in order to have two of the trigger portions 30 adjusted simultaneously. There is no need to adjust the sprinkling position separately. Therefore, steps required for adjusting are reduced and the inaccuracy of sprinkling position between the two trigger portions 30 is also reduced.
When introducing elements of the present invention or the preferred embodiments thereof, the articles "a", "an", "the" and "said" are intended to mean that there are one or more of the elements. The terms "comprising", "including" and "having" are intended to be inclusive and mean that there may be additional elements other than the listed elements.
In view of the above, it will be seen that the several objects of the invention are achieved and other advantageous results attained.
As various changes could be made in the above constructions, products, and methods without departing from the scope of the invention, it is intended that all matter contained in the above description and shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
