Abstract
In a dry shaving apparatus comprising a shaving head frame (5) detachably fixed to the basic apparatus (1) by at least one resilient latch element (2, 3) and carrying an apertured shear foil (4) and a slidable shutter (6), which serves to optionally cover or expose the apertured shear foil and which, when it is displaced in the direction away from the apertured shear foil, is displaceable into a switching-on position and subsequently into a further position, in which the motor current circuit is interrupted, it is ensured that the latch element cooperating with the shaving head frame is connected to a slide (17, 18), which is displaceable parallel to the direction of displacement of the shutter and cooperates with a spring (22, 23), which attempts to pass the slide and the latch element to the latched position holding the shaving head frame and the shutter, when it is displaced from the switching-on position to the further position, can be positively coupled after the interruption of the motor current circuit with the slide and the slide can be taken along by the shutter, the latch element being moved out of the latched position holding the shaving head frame and the shaving head f…
