Abstract

The present invention relates to hair removal, and in particular to a handheld hair removal apparatus. In order to reduce pain during hair removal, the handheld hair removal apparatus comprises a hair removal arrangement, a support structure and a skin stretching device attached to the support structure and comprising at least two leading surface portions for skin contacting and stretching. The apparatus has a main movement direction in which the apparatus is to be moved relative to skin during use. The hair removal arrangement comprises a skin contact portion for contacting a user's skin during operation, wherein the skin contact portion extends at least along a primary axis extending perpendicularly to the main movement direction During operation, the skin stretching device provides a stretched skin portion between the at least two leading surface portions.

First claim

The invention claimed is:

1. A handheld hair removal apparatus, comprising: a head portion detachably mountable to a support structure; a hair removal arrangement provided in the head portion; the support structure configured to detachably support the hair removal arrangement; the hair removal arrangement comprising a skin contact portion for contacting a user's skin during operation, said skin contact portion extending at least along a primary axis extending perpendicularly to a main movement direction in which the apparatus is to be moved relative to skin during use; a plurality of skin stretching devices that are detachably mounted to the support structure and that comprises at least two leading surface portions for skin contacting and stretching, wherein the at least two leading surface portions are each attached to the support structure, each leading surface portion extending in a substantially vertical direction from the support structure, each leading surface portion being in the shape of one-half of an elongate arch to form one-half of a v-shaped bow structure, each leading surface portion meeting at an apex coincident with a midline of an arch of said bow structure to form a closed front portion, wherein the at least two leading surface portions are each provided with a skin touching surface portion, wherein the plurality of skin stretching devices differ in at least one of size, shape and material; wherein the at least two leading surface portions are attached to the support structure in a movable manner thereby allowing relative bending movement of the at least two leading surface portions with respect to the support structure at least in a direction of a skin contact pressure, wherein the movable manner allows at least a small degree of bending substantially in the range of 10 to 15, wherein the degree of bending is dependent upon a pressure applied by a user, the at least two leading surface portions seen in an imaginary plane comprising a base line and extending parallel to the main movement direction, are arranged at opposite inclinations of at least 20 with the base line, wherein the base line is a line perpendicular to the main movement direction and parallel to the primary axis, wherein each of the skin touching surface portions, seen in said imaginary plane, has a main direction of extension that is inclined with respect to the base line at an angle of at least 20, and wherein, in the main movement direction, the leading surface portions are oriented towards each other; wherein, in an operational position, the skin stretching device is arranged in front of the skin contact portion at an inclined angle with respect to the main movement direction, and wherein the at least two leading surface portions are configured and arranged to be brought into contact with the skin, during operation, to act on the skin with a pushing force having a first vector, parallel to the skin's surface, in a first direction (Y) parallel to the main movement direction, and a second vector, parallel to the skin's surface, in a second direction (X) perpendicular to the main movement direction, wherein the pushing force acts on the skin to provide a stretched skin portion between the at least two leading surface portions.

2. The apparatus according to claim 1 , wherein the at least two leading surface portions are provided with a convex structure with respect to their outer shape facing forward in the main movement direction.

3. The apparatus according to claim 1 , wherein each of the at least two leading surface portions are provided with a surface structure that is provided with a raised front portion with respect to the main movement direction, wherein the front portions are provided as a distal tip portion extending along approximately 5% to 50% of the extension of the leading surface portions.

4. The apparatus according to claim 1 , wherein a magnitude of the second vector of the pushing force is at least 25% of a magnitude of the first vector of the pushing force.

5. The apparatus according to claim 1 , wherein the at least two leading surface portions are provided with a surface structure having a series of substantially vertically parallel elongate linear shaped ridges of varying lengths that are provided:
at an inclined angle with respect to the main movement direction; and/or
at an inclined angle with respect to a main direction of extension of the respective leading surface portions.

6. The apparatus according to claim 1 , wherein the at least two leading surface portions are provided with a flexible surface material able to provide a water-dissipating effect when said leading surface portions move along the skin surface.

7. The apparatus according to claim 1 , wherein the at least two leading surface portions are provided in a resilient manner with respect to the support structure to allow skin contact with distributed contact pressure; and
wherein the at least two leading surface portions are attached to the support structure in a movable manner allowing relative movement of the at least two leading surface portions with respect to the support structure at least in a direction of the contact pressure.

8. The apparatus according to claim 1 , wherein the at least two leading surface portions bound an area of the skin as a working area, in which the skin is stretched in preparation for hair removal following the stretching of the skin.

9. The apparatus according to claim 8 ,
wherein a light is provided to illuminate at least a portion of the skin present in said working area.

10. The apparatus according to claim 1 , wherein the hair removal arrangement comprises a hair removal component with a longitudinal axis extending perpendicularly to the main movement direction.

11. The apparatus according to claim 1 , wherein the at least two leading surface portions are provided with a surface structure having ridges that are provided:
at an inclined angle with respect to the main movement direction; and/or
at an inclined angle with respect to a main direction of extension of the respective leading surface portions.

12. A handheld hair removal apparatus, comprising: a head portion detachably mountable to a support structure; a hair removal arrangement provided in the head portion; the support structure configured to detachably support the hair removal arrangement; the hair removal arrangement comprising a skin contact portion for contacting a user's skin during operation, said skin contact portion extending at least along a primary axis extending perpendicularly to a main movement direction in which the apparatus is to be moved relative to skin during use; a plurality of skin stretching devices that are detachably mounted to the support structure and that comprises at least two leading surface portions for skin contacting and stretching, wherein the at least two leading surface portions are each attached to the support structure, each leading surface portion extending in a substantially vertical direction from the support structure, each leading surface portion being in the shape of one-half of an elongate arch to form one-half of a v-shaped bow structure, each leading surface portion being inclined towards an apex coincident with a midline of an arch of said bow structure to form an open front portion having a separation distance therebetween, wherein the at least two leading surface portions are each provided with a skin touching surface portion, wherein the plurality of skin stretching devices differ in at least one of size, shape and material; wherein the at least two leading surface portions are attached to the support structure in a movable manner thereby allowing relative bending movement of the
