Refrigerating device with height-adjustable carrier for refrigerated goods

Abstract

The invention relates to a refrigeration device having a thermally insulating housing delimiting an interior space and a height-adjustable carrier for supporting refrigerated goods within the interior space. The refrigeration device also includes a threaded spindle having a threaded extent having a substantially vertical axis, the threaded spindle being rotatably driven such that its threaded extent rotates about the axis and the threaded spindle being operationally connected with the refrigerated goods carrier such that a rotational movement of the threaded extent of the threaded spindle effects a height adjusting displacement of the refrigerated goods carrier.

1 - 11 . (canceled) 
   
   
       12 . A refrigerating device comprising:
 a.) a thermally insulating housing delimiting an interior space;   b.) a height-adjustable carrier for supporting refrigerated goods within the interior space; and   c.) a threaded spindle having a threaded extent rotatable about a substantially vertical axis, the threaded spindle being rotatably driven such that its threaded extent rotates about the axis and the threaded spindle being operationally connected with the refrigerated goods carrier such that a rotational movement of the threaded extent of the threaded spindle effects a height adjusting displacement of the refrigerated goods carrier.   
   
   
       13 . The refrigerating device as claimed in  claim 12 , wherein the threaded spindle is rotationally driven by a motor. 
   
   
       14 . The refrigerating device as claimed in  claim 13  and further comprising at least one limit switch actuated by the carrier for refrigerated goods and disposed on the threaded spindle. 
   
   
       15 . The refrigerating device as claimed in  claim 14 , wherein the threaded spindle is coupled via a worm drive to a horizontal output shaft of the motor. 
   
   
       16 . The refrigerating device as claimed in  claim 12 , wherein the carrier for refrigerated goods is supported on two rotationally coupled threaded spindles. 
   
   
       17 . The refrigerating device as claimed in  claim 16 , wherein a worm drive is associated with each threaded spindle and the two worms are operatively coupled to a common shaft operable to effect synchronized rotations of the two worms. 
   
   
       18 . The refrigerating device as claimed in  claim 17 , wherein the common shaft is the output shaft of a motor for rotationally driving the threaded spindles and the motor is configured as a geared motor. 
   
   
       19 . The refrigerating device as claimed in  claim 17 , wherein the common shaft is coupled to the output shaft of a motor for rotationally driving the threaded spindles via a belt drive. 
   
   
       20 . The refrigerating device as claimed in  claim 12 , wherein the threaded spindle is received in a vertical guide groove attached to a wall of the thermally insulated housing. 
   
   
       21 . The refrigerating device as claimed in  claim 20 , wherein the guide groove includes an undercut and the threaded spindle is disposed in the undercut. 
   
   
       22 . The refrigerating device as claimed in  claim 20 , wherein the guide groove has detent shoulders along an extent thereof for engaging a second carrier for refrigerated goods that is not supported on the threaded spindle.
