Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates generally to a gardening implement, and more particularly to a garden sprinkler. 
     2. Description of Related Art 
     There are a variety of garden sprinklers available in the market place today. These conventional garden sprinklers are generally defective in design in that they are incapable of a uniform irrigation of garden, lawn, golf course, etc., thereby resulting in waste of water. 
     BRIEF SUMMARY OF THE INVENTION 
     The primary objective of the present invention is to provide a swinging garden sprinkler which is capable of watering a lawn, garden, golf course, and the like in an even manner such that both over-irrigation and under-irrigation are averted. 
     In keeping with the principle of the present invention, the foregoing objective of the present invention is attained by a swinging garden sprinkler comprising a housing member, a driving member, a transmission member, and two spray members. The housing member is provided in the interior with a receiving space in which the driving member and the transmission member are disposed. The two spray members are pivoted to the housing member such that the spray members are engaged with the transmission member. The spray members are capable of changing the spray angle from time to time so as to avert the over-irrigation and the under-irrigation, thereby resulting in an efficient utilization of water resource. 
     The objective, features, functions and advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of the present invention with reference to the accompanying drawings.

     DETAILED DESCRIPTION OF THE INVENTION 
     As shown in all drawings provided herewith, a garden sprinkler embodied in the present invention comprises a housing member  10 , a driving member  20 , a transmission member  30 , and two spray members  40  and  41 . 
     The housing member  10  is formed of a plurality of housing pieces  11 ,  12 ,  13 ,  14 , and  15 , which form and define jointly a receiving space (not shown in the drawings) in which the driving member  20  and the transmission member  30  are mounted. The housing member  10  is provided with a water inlet  50  which is connected at one end with a water hose. The housing member  10  is mounted on a support frame  51 . 
     The driving member  20  is formed of a plurality of driving pieces which are provided with a pivoting hole and a water hole and are located by a locating shaft  21 . The driving pieces are further provided with an engagement gear. 
     The transmission member  30  is formed of a plurality of transmission pieces which are located by the locating shaft  21  and are provided with an engagement gear. The transmission member  30  is engaged with the driving member  20 . 
     The spray members  40  and  41  are provided with a water admitting port  43  and a water discharging port  42 . The spray member  40  is provided with two engagement gears  44  and  45 , whereas the spray member  41  is provided with two engagement gears  46  and  47 . The spray members  40  and  41  are engaged with the transmission member  30 . 
     The driving member  20  further comprises a locating member  22 , a locating shaft  21 , a water admitting member  23 , a press member  24 , a water distributing member  25 , and a revolving member  26 . The locating shaft  21  is put through the through holes  231 ,  241 ,  251 , and  261  of the transmission member  30  and the driving member  20 . Two elastic elements  52  are slantingly disposed by the disposing blocks  242 ,  243 ,  252 ,  253  of the press member  24  and the water distributing member  25 . The revolving member  26  is provided with an engagement gear  264  which is engaged with the transmission member  30 . The revolving member  26  is provided in the interior with a plurality of ribs  262  which are circularly arranged at an interval  263 . The water admitting member  23 , the press member  24 , the water distributing member  25 , and the revolving member  26  are disposed in the locating member  22  of a cylindrical construction. The press member  24  is provided along the fringe with a plurality of retaining blocks  244 . The locating member  22  is provided in the inner wall with a plurality of retaining slots  221  for retaining the retaining blocks  244  of the press member  24 . The locating member  22  is further provided in the inner wall with an inner engagement gear  222  for engaging the transmission member  30 , as shown in FIGS. 2,  3 A,  4 B,  7 A , and  7 B. 
     The transmission member  30  may further comprise a plurality of transmission gears  31 , pivoting disk members  32 , and action gears  34 , as well as a transmission disk member  33  and an action carrying gear  35 . The pivoting disk members  32  are provided with two pivots  322  for pivoting the transmission gears  31 , and are further provided with a gear shaft  323  for engaging the two transmission gears  31 . The pivoting disk members  32  are provided with a through hole  321  for receiving therethrough the locating shaft  21 . The transmission gears  31  are engaged with the inner engagement gear  222  of the locating member  22 . The two action gears  34  are engaged with the engagement gears  44  and  46  of the spray members  40  and  41 . The action gear  34  and the action carrying gear  35  are engaged with the engagement gears  45  and  46  of the spray members  40  and  41 . The action carrying gear  35  has a stepped gear  351  which is engaged with the gear shaft  333  of the transmission disk member  33 , as shown in FIGS. 2,  3 B,  4 B, and  6 . 
     As shown in FIGS. 4A,  4 B, and  5 , the housing pieces  12 ,  13  and  14  of the housing member form a receiving space which is in communication with the atmospheric air via the water inlet  50 . 
     The housing member  10  and the water inlet  50  of the swinging garden sprinkler of the present invention are made integrally. 
     The water distributing member  25  of the swinging garden sprinkler of the present invention is provided with at least two water distributing holes  254  which are different in angle. 
     In operation, water enters the receiving space of the housing member  10  via the water inlet  50 . The water flows into the spray members  40  and  41  via the water admitting ports  43  before the water is emitted via the water discharging ports  42 . In the meantime, the revolving member  26  is driven to revolve as the water enters the intervals  263  of the revolving member  26  via the water distributing holes  254  of the water distributing member  25 . The gear shaft  264  of the revolving member  26  actuates the transmission gear  31  of the transmission member  30  to turn on the pivot  322  along the inner engagement gear  222  of the locating member  22 . The motion brought about by the revolving member  26  is then imparted to the transmission disk member  33 , which is actuated to turn such that its gear shaft  333  actuates the stepped gear  351  to turn, thereby causing the action carrying gear  35  and the action gear  34  to actuate the two spray members  40  and  41  to swing up and down, as illustrated in FIGS. 3A,  3 B,  4 A,  4 B,  5 , and  6 . When the transmission gear  31  is in motion, the locating member  22  turns in the direction opposite to the direction in which the revolving member  26  turns. In light of the retaining blocks  244  of the press member  24  being located in the retaining slots  221  of the locating member  22 , and the disposing blocks  242 ,  243 ,  252  and  253  being provided with two elastic element  52 , when the spray members  40  and  41  revolve to arrive at the highest point, the water is caused by the water admitting member  23  to enter another water distributing hole to cause the revolving member  26  to turn in reverse, thereby actuating the spray members  40  and  41  to swing downward. Thereafter, the spray member  40  and  41  resume the upward movement as described above. 
     The embodiment of the present invention described above is to be regarded in all respects as being merely illustrative and not restrictive. Accordingly, the present invention may be embodied in other specific forms without deviating from the spirit thereof. The present invention is therefore to be limited only by the scope of the following claims.
