Device for driving an output mechanism

Abstract

A device for driving an output mechanism has a rotationally driveable input shaft, whereby elements are located between the input shaft and the output mechanism for transmitting a drive torque of the input shaft to the output mechanism, whereby a non-positive functional connection can be created between a first element and the output mechanism, enabling an alternating movement of the first element to be converted into a movement of the output mechanism, whereby the elements are configured such that the alternating rotational movement of the first element is capable of being converted into a translational movement of the output mechanism, wherein at least one lever element is turnably mounted on the first element, via which the lever element the first elements are functionally interconnected with at least one gripper element.

       18 . A device for driving an output mechanism, comprising a rotationally drivable input shaft; means adapted to be located between said input shaft and the output mechanism for transmitting a drive torque of said input shaft to the output mechanism, said means including first means providing a non-positive functional connection between said first means and the output mechanism to enable an alternating movement of said first means to be converted into a movement of the output mechanism, said means being formed so that the alternating rotational movement of said first means is convertable into a translational movement of said output mechanism; at least one lever element turnably mounted on said first means for interconnecting said first means with at least one gripper element.  
   
   
       19 . A device as defined in  claim 18;  and further comprising another gripper element, said two gripper elements being pivotally interconnected via a further lever mechanism and being pressable together tightly with the output mechanism depending on the alternating movement of said first means.  
   
   
       20 . A device as defined in  claim 18 , wherein said gripper element is arranged so as to extend over the output mechanism with a gripper arm which has inner sides adapted to be located closest to the output mechanism and comprising a dome directed in a direction of the output mechanism, said domes being arranged to have contact with the output mechanism.  
   
   
       21 . A device as defined in  claim 18 , wherein input shaft comprises an eccentric element which is functionally interconnected with said first means so that when said input shaft rotates, said first means are moved in alternating fashion depending on a movement of said eccentric element.  
   
   
       22 . A device as defined in  claim 18 , wherein said spring element is formed so as to apply a force for controlling the non-positive functional connection.  
   
   
       23 . A device as defined in  claim 18 , wherein said first means is formed so that a conversion ratio between the alternating rotational movement of said first means and the translational movement of the output mechanism is variable.
