A motor drives a magnetic impeller in the base which in turn drives a magnetic impeller in the receptacle which causes agitation of the fluid in the receptacle to cause the aquatic toy animal to move in a realistic fashion.

Description:
This application is based on provisional application Ser. No. 60/194,364 filed: Apr. 4, 2000. 
    
    
     FIELD OF INVENTION 
     This invention relates to a fish bowl or the like which will contain at least one toy aquatic figure which has a specific gravity approximating that of the fluid in which the figure is placed. A magnetically driven system will agitate the fluid to cause the animal in the fluid to swim in a realistic manner. This invention is unique in that the impeller mechanism for agitating the fluid is positioned within the display receptacle or bowl which is separatable from the base and not connected thereto. 
     BACKGROUND OF THE INVENTION 
     Fluid display apparatus for fish and other aquatic animals are shown in U.S. Pat. Nos. 5,301,444, 5,405,465, 5,050,876, 5,603,994, 1,595,801, 3,425,157 and German Patent Patentanmeldung of Nov. 10, 1955 P12,239 XI-77f. In these patents, the animal has attached thereto a magnet which is affected by a second magnet which passes by the first magnet either by manual or motor means. 
     Some similar magnetic driving devices are shown in U.S. Pat. Nos. 4,757,986, 4,852,283, 3,006,111 and 5,146,701. In these patents, the animal figure responds through a magnetic field. In the case of U.S. Pat. No. 5,146,701, the container is moved by a magnetic field. In the case of U.S. Pat. No. 3,006,111, a magnetic field causes movement of the figure which is not encased or otherwise positioned in a fluid receptacle. In the case of U.S. Pat. No. 4,757,986, the magnets drive a figure rotationally on a non-moving platform. In the case of U.S. Pat. No. 4,852,283, the moving device can stir the debris of articles in the fluid to cause them to move about to mimic a rain or snow fall. 
     OBJECTS AND SUMMARY OF THE INVENTION 
     It is an object of this invention to provide a mechanism within a tank, bowl or receptacle which will agitate the fluid so as to cause an aquatic toy animal or the like to move with the fluid current. 
     Another object of this invention is to provide an aquatic display device which has a tank which is removable and separate from the base upon which it sets and is not glued or otherwise secured thereto. This allows for washing of the receptacle periodically when the fluid therein discolors. 
     Still another object of this invention is to provide a rotating mechanism within the tank which will agitate the fluid in various directions so as to cause the aquatic toy animal or the like to move realistically in the tank or bowl. 
     Yet another object of this invention is to provide an aquatic toy animal display apparatus which is inexpensive to manufacture. 
     Still another object of this invention is to provide an aquatic display apparatus which includes an impeller which agitates the fluid which can also be removed from the tank for cleaning and the like. 
     A further object of this invention is to provide a base platform which does not have to be sealed from the fluid which is in the tank. 
     In summary, this invention relates to aquatic toy animals positioned in a tank, receptacle or the like which are influenced by the motion of the fluid therein. 
     These and other objects of this invention will be apparent from the following detailed description including the drawings which are as follows:

     DETAILED DESCRIPTION OF THE INVENTION 
     FIGURE  1   
     FIG. 1, the apparatus A includes a base B and a receptacle, bowl or tank R. The receptacle R is closed at the bottom  2  and open at the top  4 . The receptacle R is transparent and made of plastic or glass and is filled with colorless fluid, preferably water  6 . 
     As shown in FIG. 1, a receptacle R holds simulated aquatic toy fish  8  which are of a specific gravity substantially the same as the fluid  6 . Under non-operating conditions, the simulated toy fish  8  would rest at the bottom  2  of the receptacle R, and upon agitation of the fluid  6 , the simulated toy fish  8  will move about and receptacle R in a life-like fashion simulating real fish. The simulated toy fish or animals or the like  8  are non-magnetic and can be fashioned from plastic, glass or other materials having a specific gravity similar to that of the fluid  6 , or the materials from which they are made might be heavier and the specific gravity of the fluid requiring an air chamber to effectively produce a simulated toy fish  8  which does have a specific gravity similar to that of the fluid  6 . 
     For cleaning purposes, a receptacle, bowl or tank R can be lifted from the base B and cleaned and washed and filled with fluid  6  as desired. The receptacle R is unattached to the base B and rests thereon in a base recess  10 . It should be noted in FIG. 1 that the bottom  2  of the receptacle R is somewhat concaved. This concavity of the bottom  2  is preferred but not absolutely essential. The concavity of the bottom  2  aids in positioning of the housing H. The housing H includes pads or feet  12  which rest on the bottom at the ends of the concavity of the bottom  2  for ready positioning. A pressure sensitive adhesive may be applied to the pads  12  to secure the housing H to the bottom  2 . For cleaning purposes, the housing H may be readily removed from the receptacle R. 
     As best shown in FIGS. 7 and 8, the housing H is provided with inlet orifices or perforations  14  or outlet orifices or perforations  16 . The outlet orifices  16  may be positioned in the housing H so as to direct the fluid  6  in an inward angular direction as shown by the arrows in the FIG.  8 . The inlet perforations  14  and the outlet perforations  16  may be placed in a scenic environment molded into the housing H which scenes might include sea mounts  18  and  20 . The housing H includes a recess  22  for receiving a rotatable impeller P. The impeller P rotates around an axle pin  24  which is inserted into the pin receiving opening  26  (FIG.  7 ). The axle pin  24  extends thought the impeller sleeve  28 . 
     The impeller P, as best shown in FIG. 7, has magnetic members  30  mounted therein. Radially disposed about the impeller P are flutes  32  which include a flute step  34 . The flutes  32  including the flute steps  34  are radially disposed about the impeller P. When the impeller P is driven, the fluid  6  coming through the inlet orifices or perforations  14  is thrown outwardly and exits the outlet orifices or perforations  16  or under the housing H and around the pads or feet  12 . It will be obvious that at least one inlet orifice  14  is necessary to bring water or fluid  6  into the impeller P, although the outlet orifices  16  are preferred. Agitation of the fluid will occur when the impellers pushes the water  6  out under the housing H around the pads or feet  12 . The impeller P should not fit tightly against-the recess  22 . It further spins freely about the axle pin  24 . 
     The base B is formed of two halves; namely the upper half  36  and the lower half  38 . The upper half  36  includes a button switch  40  connected to a battery or other electrical power source  42  which in turn is connected to a motor M. The motor M is connected to a drive train or speed reduction gearing  44  generally shown in FIG. 5. A drive shaft  46  from the drive train or speed reduction gearing  44  drives a first impeller  48  having positioned thereon magnetic member  50  and  52 . The magnetic members  50  and  52  rotate about the drive shaft  46  when the motor M is turned on by pushing the button switch  40 . A rheostat control  54  may be positioned on the base B for adjusting the speed of the first impeller  48 . 
     In the base B in the bottom half  38 , a door  56  for the battery  42  is provided for replacing the battery  42  as required. 
     OPERATION 
     In operation, the first impeller  48  upon rotation will cause the impeller P to move due to the magnetic influence of the magnetic members  50  and  52  of the first impeller  48  on the magnets  30  of the impeller P. Rotation of the impeller P draws fluid into the orifices or perforations  14  and projects it by means of the flutes  32  and flutes steps  34  outwardly toward the outlet orifices  16  as well as under the impeller P out the recess  22  and around the pads or feet  12 . This movement of the fluid  6  stirs up the fluid  6  causing the simulated toy animal such as the fish  8  to swim about the receptacle R. As mentioned earlier removal of the receptacle R as well as the housing H can be accomplished without damage to the base B which houses the motor M and the drive train mechanism  44  and impeller  48 . 
     While this invention has been described as having preferred design, it is understood that it is capable of further modification, uses and/or adaptations following in general the principle of the invention and including such departures from the present disclosure as come within known or customary practice in the art to which the invention pertains, and as may be applied to the essential features set forth, and fall within the scope of the invention or the limits of the appended claims.
