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

A shaver comprising:

• a handle,
• at least two rotary shaving heads, each of the at least two rotary shaving heads being respectively driven by a corresponding dedicated drive shaft which protrudes from said handle, and
• a central support structure configured to support the at least two rotary shaving heads onto said handle, so as to have their joined shaving surface extend substantially perpendicular to each of the corresponding dedicated drive shafts,
• wherein the corresponding dedicated drive shafts are located eccentrically with respect to a respective corresponding shaving head to be driven,
• wherein the central support structure is configured to limit an upward pivot angle of the at least two rotary shaving heads to enable a concave, convex, or straight shape of the shaving surface in a neutral position,
• wherein the central support structure is further configured such that a space, restricted at one side by the at least two rotary shaving heads and at its opposite side by the handle, is substantially open to its remaining, surrounding side,
• wherein the support structure supports the at least two rotary shaving heads at a fixed number of isolated points spaced centrally between the at least two rotary shaving heads,
• wherein each of the corresponding dedicated drive shafts are at least partially enclosed by the central support structure.
