A depilating device () comprises a depilating body () which is rotatable about a rotation axis (R) extending in a longitudinal direction (L) with respect to the depilating body () and which is provided with at least one hair-catching space (). The depilating device () further comprises an actuating mechanism () configured to act on the depilating body () so as to cause compression and extension of the depilating body () in the longitudinal direction (L) during rotational movement of the depilating body () about the rotation axis (R), for the purpose of varying the size of the hair-catching space () of the depilating body () in the longitudinal direction (L), wherein the actuating mechanism () includes a force-inducing member () which is compressible and extensible in the longitudinal direction (L) and which has a function in determining the level of a hair-clamping force in the depilating body ().

Depilating device

A two-dimensional force sensor for measuring a first force in a first direction and a second force in a second direction. The sensor comprises a first resilient plate oriented in the second direction, a first end of the first resilient plate being arranged for being coupled to a reference point; a second resilient plate oriented in the first direction, a first end of the second resilient plate coupled to a second end of the first resilient plate and a measurement probe coupled to a second end of the second resilient plate. The measurement probe is mounted on an extension device mounted to the second end of the second resilient plate. The extension device positions the measurement probe at a position deviating from an imaginary cross-section point of the first resilient plate and the second resilient plate by no more than 20% of a length of the extension device.

The invention relates to a skin treatment device for removing callus from the skin by an abrasive treatment, comprising a housing with a handle section (), a skin treatment element () rotatable around a rotational axis () and a protective rim (). Said protective rim circumferentially encases said skin treatment element partially over an angular range of more than 120&#xb0; and less than 330&#xb0; about said rotational axis such that a circumferential abrasive treatment surface protrudes from the protective rim in an area extending over an angular range of 30&#xb0; to 240&#xb0;.

Apparatus for callus removal

A skin treatment head includes treatment head surface; multiple bristles extending from the treatment head surface and defining a virtual edge face circumferentially surrounding the bristles and a virtual top face defining a first height of the bristles; and one or more rotatable elements extending from the treatment head surface and having a second height lower than the first height, such that in order to apply a tangential force to rotate the rotatable elements, the skin treatment head is tilted relative to a skin surface.

A device for measuring hair properties has a first part (I) and a second part (II) between which hair (H) is guided. The first part includes a measuring probe (MP), and the second part is arranged for deforming the hair against the measuring probe. While the device moves along the hair, the measuring probe experiences both a friction force resulting from the hair being guided along the measuring probe, and a deformation force resulting from hair deformation by the second part against the measuring probe. The second part includes a pressure element (PB, S) for pressing the hair against the measuring probe. In alternative embodiments, the second part comprises alignment elements (AE) at opposite sides of the measuring probe, and guidance elements (G) for mitigating an influence of an angle at which the device is applied to the hair to the friction force and/or the deformation force.

Device for measuring hair properties

There is disclosed a coupling unit () for transmission of a rotary driving force, comprising a first coupling member () having a curved first bearing surface () and a second coupling member () having a main coupling body () and a curved second bearing surface engaging the first bearing surface thereby enabling rotation of the second coupling member () relative to the first coupling member (). The second coupling member comprises at least two carrying elements () which are each provided with a respective one of at least two second bearing surface segments () of the second bearing surface that engage the first bearing surface. At least two connecting elements () of the second coupling member () each connect a respective one of the at least two carrying elements () with the main coupling body () and comprise an elastically deformable material. In a first deformed condition the elastically deformable material provides a first biasing force urging the at least two second bearing surface segments () into contact with the first bearing surface. A blocking element () of the first coupling member () is arranged between the first bearing surface () and the main coupling body () and is configured to prevent passage of the carrying elements () along the blocking element at least in the first deformed condition. In a second deformed condition of the elastically deformable material, wherein the elastically deformable material provides a second biasing force larger than the first biasing force, the carrying elements () are able to pass along the blocking element.

Coupling unit

A skin treatment head for use in a body care device for treating a skin, the body care device comprising a housing and a skin treatment head associated with the housing, wherein the housing further comprises an actuator configured to at least partly rotate the skin treatment head about an axis (A), wherein the skin treatment head comprises a plurality of bristles defining a virtual edge face circumferentially surrounding the plurality of bristles and a virtual top face defining a first height (h) of the bristles relative to a skin treatment head surface of the skin treatment head, wherein the skin treatment head further comprises a plurality of rotatable elements, wherein each rotatable element is configured to rotate when a force in a tangential direction is applied to a rotatable element surface of the rotatable element, wherein the rotatable element surfaces are configured lower than the top face and wherein in certain embodiments the rotatable element surfaces at least partly extend beyond the edge face.
