Patent ID: 8732964

Claim:
A hair removal device ( 100 ) comprising a) a main device element ( 10 , 20 ) which comprises the major portion of the total weight of the hair removal device ( 100 ), and b) a separate element ( 30 , 40 ) which is detachably connected with the main device element ( 10 , 20 ) by means of a coupling comprising a spring element ( 90 ) which is loaded to provide a spring force such that the coupling is not released by the spring force, latching elements ( 23 , 33 ) characterized in that the latching elements ( 23 , 33 ) at least partially grip each other along a circle around an axis (A) of rotation, said latching elements ( 23 , 33 ) having sliding surfaces ( 25 a , 25 b , 35 a , 35 b ) inclined to the axis of rotation (A) which press the latching elements axially apart when the latching elements rotate around the axis of rotation such that when a drop energy force acting on the separate element ( 30 , 40 ) exceeds about 2.2 Joules, the separate element ( 30 , 40 ) uncouples from the main device, element ( 10 , 20 ), wherein the uncoupling occurs upon a relative rotation between the main device element ( 10 , 20 ) and the separate element ( 30 , 40 ) and wherein upon uncoupling the separate element ( 30 , 40 ) and main device ( 10 , 20 ) are pushed away from each other by expansion of said spring element ( 90 ) and the separate element ( 30 , 40 ) comprises a replaceable blade cartridge.
