Abstract:
A juice maker uses a handle to control an upper mold to move upward or downward, which corresponds to a lower mold at underneath, and the lower mold is controlled by the handle to turn, when the upper mold is driven to move upward or downward, the lower mold will turn to squeeze juice from a fruit seating in a barrel of the machine.

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates to a juice maker, more particularly to a machine to squeeze fruit to get juice. 
     2. Description of the Prior Art 
     A conventional juice maker comprises an upper mold and a lower mold corresponding to the upper mold.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     A juice maker of the present invention comprises a base  1  to be seating on a flat surface, a transmission mechanism  2  secured on its top portion thereof, and a receiving seat  3  at its center thereof, as shown in FIG.  1 . 
     The transmission mechanism  2  comprises a wheel  21  in its center portion with a rectangle-shaped hole  211  at center thereof for insertion of a shaft of a handle  22  through there and then sealed by a snap ring  221  from the other side, a cover  23  is used to cover the wheel  21  in the transmission mechanism  2 . The transmission mechanism  2  further comprises a shaft  24  with gear holes thereon, which meshes with the gear of the wheel  21 . The bottom end of the shaft  24  is connected with an upper mold  25  which comprises a driving gear  251  at its bottom end. When moving the handle  22 , the transmission mechanism  2  drives the shaft  24  to roll up or down, which then brings the upper mold  25  to move, simultaneously. 
     The receiving seat  3  has a hollow body located underneath the upper mold  25 , and is composed of a barrel  31  and a lower mold  32 . The barrel  31  has a ring stopper  311  at its bottom edge and a funnel  312  at the bottom end. The funnel  312  has a lug  313  at one side. The lower mold  32  has a conical seat  321  corresponding to the slope shape of the upper mold  25  with star-shaped. The bottom end of the conical seat  321  has a driven gear  322  and the receiving seat  31  has ribs  314  which engage with notches  323  of the conical seat  321 . 
     To assemble, as shown in FIG. 2, the barrel  31  with a torque spring  4  are placed in the receiving seat  3 , one end of the torque spring  4  is secured in the lug  313  of the barrel  31 , while the other end of the torque spring  4  is secured to the bottom end of the receiving seat  3 , that provides a restoring force to the barrel  31 . The lower mold  32  is slid into the receiving seat  3  with the notches  323  line up with the ribs  314  until the bottom end of the lower mold  32  reaches the stopper  311  of the barrel  31 . 
     To operate the juice maker, as shown in FIGS. 3 and 4, the handle  22  is pulled, which links the wheel  2  to move, and then links the upper mold  21  to move up or down. When the driving gear  251  of the upper mold  25  reaches the driven gear  322  of the lower mold  32 , the lower mold  32  and the receiving seat  31  will be forced to rotate, when the upper mold  25  moves upward away from the lower mold  32 , the torque spring  4  urges the lower mold  32  and the receiving seat  31  return to its original position. 
     When the upper mold  25  moves downward and press the lower mold  32  (before the driving gear  251  engaging with the driven gear  322 ), most particles of the fruit will be squeezed. Upon the driving gear  251  reaches to the driven gear  322 , those particles remain in the comer or the valley of the conical seat  321  will be pressed to release juice. 
     A second embodiment of a juice maker of the present invention, as shown in FIG. 5, comprises a base  5  and a transmission mechanism  6  secured on the top portion thereof. The transmission mechanism  6  has an upper mold  64  attached to the top and a transmission shaft  63  extending downwardly. The transmission shaft  63  with gears meshes with a gear  62  which is controlled by a handle  61 . A receiving seat  51  is formed underneath the upper mold  64  with a hole  511  at its center portion to accept a pair of driving gears  52  and  53  therein. The driving gear  52  meshes with the transmission shaft  63  of the transmission mechanism  6 , whereas the other driving gear  53  is formed with groves  532  on the inner wall of a hole  531  for corresponding ribs  711  of a post  71  of a barrel  7  for securing purpose. The barrel  7  comprises a number of ribs  72  along its inner sidewall adapted for corresponding notches  81  of a lower mold  8  to slide thereat. 
     To assemble the present invention, as shown in FIGS. 6 and 7, the gear  62  is slid into the base  5 , and the handle  61  is inserted sideway into the base  5  through a center hole of the gear  62 , the post  71  of the barrel  7  is inserted into the hole  511  of the receiving seat  5  with the ribs  711  sliding into the grooves  532  of the hole  531  of the driving gear  53 , then the lower mold  8  is placed into the barrel  7  with the notches  81  sliding along the ribs  72 . 
     To operate the present invention, the handle  61  is rolled down, which links the transmission shaft  63  sliding down and the driving gears  52  and  53  will be activated simultaneously, which links the lower mold  8  and the barrel  7  to rotate. When the handle  61  is pulled upwardly, the driving gears  52  and  53  will bring the barrel  7  return to its original position. 
     Both of the above embodiments depict a rotation movement of the lower mold when the upper mold is moved, thus, the present invention is characterized in that press down and rotation. 
     While there has been described and illustrated two specific embodiments of the invention, it will be clear that variation in the details of the embodiments specially illustrated and described may be made without departing from the true spirit and scope of the invention as defined in the appended claims, such as the handle may be in up and down movement or in a rotation movement, and the gears may be in any other forms.
