Patent ID: 7614595

Claim:
A mobile telephone/PDA holder mechanism, comprising a hollow base body for supporting a telephone/PDA holder apparatus, said mechanism being disposed in the base body ( 1 ) and comprising two clamping jaws ( 2 , 3 ) supported on the base body ( 1 ) so as to be movable synchronously and uniformly away from, and toward, each other, guide legs ( 21 , 31 ) projecting from said clamping jaws ( 2 , 3 ) and being slidably guided in said base body ( 1 ), a coupling element ( 7 ) rotatably supported in said base body ( 1 ) and being coupled at opposite sides with the guide legs ( 21 , 31 ), via a pin-slot connection, a compression spring arrangement biasing the clamping jaws ( 2 , 3 ) in an opening direction, a locking wheel ( 12 ) connected to the coupling element ( 7 ) for rotation therewith and a locking element ( 13 ) arranged adjacent the locking wheel ( 12 ) and being spring biased into contact with the locking wheel ( 12 ) so as to prevent rotation of the locking wheel ( 12 ) in a jaw-opening direction, but permitting rotation of the locking wheel ( 12 ) in a jaw-closing direction, and a release key ( 14 ) for disengaging the locking element ( 13 ) from the locking wheel ( 12 ) so as to permit the rotation of the locking wheel ( 12 ) in a clamping jaw opening direction, said locking wheel ( 12 ) being provided with an elastically deformable circumferential surface area ( 16 ) and the locking element ( 13 ) being a locking shoe with a plurality of teeth ( 17 ), which are arranged in a circumferentially spaced relationship on the locking shoe ( 17 ) and have a flat saw-tooth profile and, for engagement with the locking wheel ( 12 ), are pressed into the resilient circumferential surface of the locking wheel ( 12 ).
