Rotary shavers, with improved drive and support structure for the shaving heads

摘要

A shaver (1) includes a handle (2), at least two rotary shaving heads (5), driven by at least one drive shaft (15; 115; 215) which protrudes from the handle (2), and a support structure (6) for supporting the shaving heads (5) onto the handle (2) so as to have their joined shaving surface(s) extend substantially perpendicular to the at least one drive shaft (15; 115; 215). The support structure (6) is configured such, that a space (A), restricted at one side by the shaving heads (5) and at the opposite side by the handle (2), is substantially open to its remaining, surrounding side.

1. A shaver comprising:
a handle; at least two rotary shaving heads each having a shaving surface and a bottom side, wherein each shaving head further comprises an internal cutting member that is provided with a gear wheel directly fastened to the internal cutting member via a base plate of the internal cutting member without intermediate components, further wherein the bottom side of each shaving head comprises a substantially ring shaped subholder; at least one drive shaft protruding from said handle for driving said at least two rotary shaving heads; and a support structure for supporting said shaving heads onto said handle such that the shaving surfaces of the at least two rotary shaving heads form a joined shaving surface extending substantially perpendicular to said at least one drive shaft, wherein the substantially ring shaped subholders of said shaving heads are each pivotally connected around a respective pivot axis to the support structure to enable a concave, convex, or straight shape of the joined shaving surface, and wherein the support structure is configured in such way that a space (A), restricted at one end by the bottom sides of the shaving heads and at an opposite end by the handle, is substantially open to its remaining, surrounding side.
