Full Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Technical Field  
         [0002]     This invention relates to a device to enable an adult to efficiently attend to an infant by providing a folding, rotatable, adjustable surface on which to place an infant to change the diaper of said infant in an automobile.  
         [0003]     2. Description of Prior Art  
         [0004]     A search of prior art revealed:  
         [0005]     U.S. Pat. No. 4,876,970 sets forth a coin operated, wall mounted fold down child diaper changing table that is placed in public lavatories for parents with an infant, who are just out and about, or traveling.  
         [0006]     U.S. Pat. No. 2,735,737 describes a diapering support comprising a wall mounted housing supporting a roll of disposable paper to be drawn downward from the housing. The housing itself contains a multi-hinged flat surface secured at one end and two folding arms on the other.  
         [0007]     U.S. Pat. No. 2,817,571 sets forth a wall mounted folding table secured by means of a plurality of articulating arms and springs provided for locking said table in the down or extended position during non-use to be folded back against the support wall.  
         [0008]     U.S. Pat. No. 4,613,996 sets forth a folding child support secured to a wall surface in a rectangular enclosure. The enclosure contains a plurality of compartments and shelves as well as utility features mounted therein. The enclosure includes a hingeably secured pivotable outer surface in the closed position and an extended position forming a child care surface.  
         [0009]     Other practitioners have provided examples of folding table mechanisms included in: U.S. Pat. Nos. 2,815,700, 2,857,222, 3,232,663 and 3,689,344.  
         [0010]     The foregoing examples provided various mechanisms for wall mounted infant care fold down tables and some during traveling, but none provided an in car folding, adjustable table, should the traveler not be near a public facility when needed.  
       SUMMARY OF THE INVENTION  
       [0011]     The object of this invention is to present an on board, in car, folding adjustable infant care station for the traveler to be utilized whether or not a public facility is available by merely pulling off the road and attending to the needs of the child without leaving the automobile. 
     
    
     DESCRIPTION OF THE DRAWINGS

     DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0016]      FIG. 1  sets forth a right oblique view of the front seat of an automobile affixed with the Portable Infant Auto Changing Table in the folded, or travel mode. The automobile seat  11  supports the head rest  12  with the Portable Infant Auto Changing Table frame  13  resting on the top of the back support  11  and forward of the head rest  12 . The frame  13 , extends vertically downward on each side of the seat back support  11 , to the bottom of said seat back support and horizontally rearward to the vertical adjustment mechanism  14 . The vertical adjustment mechanism  14  is adjustably affixed to the vertical support bar  15  and extends upward from the horizontal frame  13  to the center of the changing table  16 . The changing table  16  is folded vertically against the rear surface of the back support portion of the seat  11 , by activating both the table vertical adjustment mechanisms  14  and  17 , located at each end of the vertical support bar  15 . The utility trays  19  are affixed to the two descending portions of the frame  13 . The Portable Infant Auto Changing Table can be affixed to the head rest  22  by simply holding said table components in the horizontal position above the head rest, lowering the frame  23  in front of the head rest  22  until coming to rest on the top portion of the seat support  21  and rotating the Portable Infant Changing Table downward until it comes to rest on the rear surface of the seat back support  21 . To remove the Portable Infant Auto Changing Table, simply reverse the procedure.  
         [0017]      FIG. 2  shows a left view of the front seat  21 , of an automobile and the head rest  22 , with the frame  23  resting around the front bottom portion of the head rest  22 , affixing it to the seat back support  21 . The utility tray  24  is affixed to the descending portions of the frame  23 . The table  25  is folded and resting on the rear surface of the back support portion of the seat  21 . The vertical support bar  28  has two adjustment mechanisms  27  and  29 , located at each end. The horizontal rotation control mechanism  26  allows the operator to adjust the table to the desired position when folding the table  25  for travel, or not in use.  
         [0018]      FIG. 3  depicts also the left view of the front seat of an automobile  31 , head rest  32 , supporting frame  33  and utility tray  34  with the Portable Infant Auto Changing Table  35 -A in the horizontal position to receive an infant placed on the foam pad  35 -B, rotated horizontally for convenience by activating the horizontal rotation mechanism  36 . The desired position is attained by pulling the knob  36  downward far enough to clear the table for rotation and moving the table  35 -A to that position. The table  35 -A is supported by the vertical support bar  38 , with vertical adjustment mechanisms  37  and  38  located at each end.  
         [0019]      FIG. 4  shows a front view of the adjustment mechanisms. The fixed disc  41  is affixed to the frame portion  42  and contains a plurality of holes  46 , strategically placed to accept the rotationally adjustable peg  45  attached to the pull knob  44  affixed to the spring bar  43  which is further attached to the rotational bar  42 .  
         [0020]      FIG. 5  describes a side view of the adjustment mechanism.  51  is the stationary disc containing a plurality of strategically spaced holes  56 , so when the adjustment knob  54  is pulled, the adjustment peg  55  is dislodged from the adjustment hole  56  and can be rotated to the desired position. By releasing the knob  54 , the locking peg  55  is forced into an adjustment hole  56  by the spring action of the spring bar  53 , that is rotationally attached to the rotational bar  52 .
