Embodiment Construction

[0022] The same reference numerals are used to designate corresponding elements in the following description of the embodiments.

[0023] figure 1 A rotary shaving appliance is shown with a housing 1 and a shaving head holder 2 which is detachable from the housing and / or pivotable relative to the housing. Three cutting units 3, also called shaving heads, are located in the shaving head holder, each shaving head having an outer cutting element 4 with a hair entry hole 5 and an inner hair cutting element which can be driven to rotate relative to the outer cutting element 4. Cutting piece 6. The inner cutter is driven in a known manner by an electric motor (not shown) located in the housing of the shaving appliance.

[0024] Figure 2 schematically shows a first embodiment of the invention. The figure shows a cutting unit 3 formed by an outer cutting element 4 and an inner cutting element 6 cooperating therewith. The outer cutting part 4 is in the shape of a round cap with hai...

Abstract

Shaving apparatus having at least one cutting unit with an external cutting member and a rotatable internal cutting member each the external and internal cutting members having cooperating cutting edges forming bearing surfaces of a first bearing, and a second bearing with bearing surfaces. To minimize the friction between the cutting edges, a support device having visco-elastic properties is provided between the two bearings. During operation, the distance between the bearing surfaces of the first bearing adjusts to the distance between the bearing surfaces of the second bearing. During cutting of hairs, the support device behaves as a stiff element whereas during periods in which no hairs are cut, the support device behaves relatively soft so that the cutting gaps between the cutting edges are closed.

Description

technical field [0001] The invention relates to a shaving device having a housing and at least one cutting unit comprising an outer cutting member and an inner cutting member drivable to rotate relative to the outer cutting member, said inner cutting member is provided with a cutting element (cutting element) having a cutting edge, said outer cutting member is provided with a hair trap opening limited by the cutting edge, for cutting hair said cutting edge and said cutting element cutting edges cooperating, and said cooperating cutting edges form a bearing surface for a first bearing (bearing) between the outer cutting member and the inner cutting member, the shaving apparatus further comprising a drive member for driving the inner cutting member, and A second bearing having cooperating bearing surfaces is present between the outer and inner cutters. [0002] The invention also relates to a cutting unit for a shaving device as described above. Background technique [0003]...
