1. Field of Invention
The present invention relates to gardening and, more particularly, to a light and inexpensive sprinkler apparatus for gardening.
2. Related Prior Art
A conventional sprinkler apparatus includes a sprinkler and a frame for supporting the sprinkler on the ground or sometimes a wall. The conventional frame is made of metal by casting and inevitable finishing such as grinding or sand-blasting. The amount of metal used to make the conventional frame is large. Hence, the conventional frame is heavy. The casting requires molds and is complicated and expensive. The finishing further adds to the cost of the conventional frame. Furthermore, the conventional frame is aesthetically dull because it is difficult for it to carry coatings.
The present invention is therefore intended to obviate or at least alleviate the problems encountered in prior art.
It is the primary objective of the present invention to provide a light, inexpensive and aesthetically pleasant sprinkler apparatus.
To achieve the foregoing objective, the sprinkler apparatus includes a sprinkler and a frame for supporting the sprinkler. The frame includes two lateral members and first and second cross members. Each of the first and second cross members includes two lateral edges each connected to a corresponding one of the lateral members. The lateral members and the first and second cross members are made of metal by punching.
In another aspect, the first and second cross members are secured to the lateral members by welding.
In still another aspect, each of the lateral members includes first and second slots. The first cross member includes a fin extending from each of the lateral edges thereof. The second cross member includes a fin extending from each of the lateral edges thereof. Each of the fins of the first cross member is inserted in the first slot of a corresponding one of the lateral member. Each of the fins of the second cross member is inserted in the second slot of a corresponding one of the lateral members.
Other objectives, advantages and features of the present invention will be apparent from the following description referring to the attached drawings.
The present invention will be described via detailed illustration of the preferred embodiment referring to the drawings wherein:
Referring to
The sprinkler 10 includes a valve 14 and a tube 16. The valve 14 includes a valve housing 18, a valve 20, a knob 22 and an axle 23. The valve housing 18 is made of a plastic material. The valve housing 18 is formed with two wings 19 each including an aperture 21.
The valve 20 is made of a plastic material. The valve 20 is pivotally placed in the valve housing 18.
The knob 22 is made of a plastic material. The knob 22 is placed out of the valve housing 18 and hence operable by a user.
The axle 23 is made of a plastic material. The axle 23 includes an end connected to the valve 20 and another end connected to the knob 22. The valve 20 can be pivoted by the knob 22 via the axle 23.
The tube 16 is made of metal. The tube 16 includes an arched middle portion extending between two rectilinear terminal portions that extend along a common axis. Nozzles 26 are evenly provided on the middle portion of the tube 16. The first terminal portion of the tube 16 is pivotally inserted in the valve housing 18. The second terminal portion of the tube 16 is pivotally inserted in a portion of the frame 12. The range of the pivoting of the first terminal portion of the tube 16 in the valve housing 18 is controlled by operating two limit elements 24 pivotally placed on the valve housing 18.
The frame 12 includes two symmetric lateral members 28 and two cross members 30 and 32. Each of the lateral members 28 is a hollow element made of a piece of metal by punching. Each of the lateral members 28 includes two slots 34 near an end and a slot 36 near another end.
The first cross member 30 is made of a piece of metal by punching. The first cross member 30 includes two lateral edges. Two fins 38 extend from each lateral edge of the first cross member 30. Furthermore, the first cross member 30 includes an aperture 40, a slot 42 and two openings 44. The aperture 40 is located between the openings 44.
The second cross member 32 is made of a piece of metal by punching. The second cross member 32 includes two lateral edges. A fin 46 extends from each lateral edge of the second cross member 32. The second cross member 32 further includes two upper strips 48 and a lower strip 50. The lower strip 50 is made by punching a portion of the second cross member 32 between the upper strips 48.
Preferably, the sprinkler apparatus further includes a panel 52. The panel 52 is made of a plastic material. The panel 52 includes an aperture 54. A pattern (not shown) may be provided on a side of the panel 52. The pattern is used to instruct the user to operate the knob 22 to pivot the valve 20 in the valve housing 18. Two cylinders 56 are formed on an opposite side of the panel 52. Each of the cylinders 56 includes a screw hole 58.
As clearly shown in
The valve housing 18 is placed beneath the first cross member 30. The limit elements 24 are movable in the slot 42 so that the operation of the limit elements 24 is not hindered by the first cross member 30. The panel 52 is placed on the first cross member 30, with the cylinders 56 inserted in the openings 44. Two screws 60 are inserted in the screw holes 58 through the apertures 21. Thus, the valve housing 18 and the panel 52 are firmly connected to the first cross member 30.
The valve 20 is placed in the valve housing 18. The axle 23 is inserted in the apertures 54 and 40. An end of the axle 23 is connected to the valve 20 while the other end of the axle 23 is connected to the knob 22, which is placed above the panel 52.
The second terminal portion of the tube 16 is placed between the lower strip 50 and the upper strips 48. Thus, the tube 16 is only allowed to pivot about the common axis of the first and second terminal portions thereof.
Advantageously, the sprinkler apparatus is light and inexpensive because the lateral members 28 and the cross members 30 and 32 are hollow elements made of pieces of metal. Another reason for the low cost of the sprinkler apparatus is that the lateral members 28 and the cross members 30 and 32 are made by punching, which is simpler and less expensive than casting. Furthermore, the sprinkler apparatus is aesthetically pleasant since various coatings can be provided on the lateral members 28 and the cross members 30 and 32.
The present invention has been described via the detailed illustration of the preferred embodiment. Those skilled in the art can derive variations from the preferred embodiment without departing from the scope of the present invention. Therefore, the preferred embodiment shall not limit the scope of the present invention defined in the claims.
