Abstract:
1. A shaver comprising a shaving head including at least one cutting blade and two skin-supporting members, the cutting blade having a cutting edge extending perpendicularly to a shaving direction of the shaving head, and the skin-supporting members being arranged, viewed in the shaving direction, respectively, in front of and behind the cutting blade and extending substantially in a contact surface wherein, in operation, the shaving head contacts a skin surface to be treated, while the cutting blade and the skin-supporting members are secured to a sub-frame, which is coupled to a main frame and can be displaced, against a spring force, with respect to the main frame, wherein: the main frame comprises two further skin-supporting members which, viewed in the shaving direction, are arranged, respectively, in front of and behind the sub-frame and which extend substantially in the contact surface; the sub-frame is secured to the main frame by means of a mechanical spring unit, and is at least tiltable with respect to the main frame about two mutually perpendicular tilt axes and displaceable with respect to the main frame in a displacement direction perpendicular to said tilt axes, thereby deforming the spring unit; the mechanical spring unit comprises a central portion and two pairs of leaf springs facing away from each other, which leaf springs each extend from the central portion in a direction substantially perpendicular to the shaving direction, and each support the sub-frame at a location close to a corner, and the central portion of the spring unit is provided with a sphere segment-shaped supporting element with which the spring unit rests against the main frame.
