<p>#CMT# #/CMT# The drive device has two shaft holding parts, a joint housing, a joint cam coupled to the second shaft holding part to inhibit its rotation and enable axial motion, a joint shaft that interacts with the cam to define flap opening and closing positions, an elastic element between the cam and joint housing to exert an elastic force on the cam to bias the cam against the joint shaft and a drive arrangement for transferring a torque to the shaft. #CMT# : #/CMT# The drive device has first and second shaft holding parts (51,52), a cylindrical joint housing (62), a joint cam (78) coupled to the second shaft holding part so as to inhibit its rotation and enable axial motion, a joint shaft (77) that interacts with the cam to define opening and closing positions of the flap, an elastic element (79) between the cam and joint housing to exert an elastic force on the cam to bias the cam against the joint shaft and a drive arrangement (73,74) for transferring a torque to the joint shaft. #CMT#USE : #/CMT# For driving a flap on a portable device. #CMT#ADVANTAGE : #/CMT# Enables improved assembly and adaptation of component parts with no reduction in the torque generated by a motor. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic sectional representation of an inventive flap drive device for a portable device. 51,52 : first and second shaft holding parts 62 : cylindrical joint housing 78 : joint cam 77 : joint shaft 79 : elastic element 73,74 : drive devices.</p> |
