Abstract

A hand held device for removing hard skin from calluses comprises a handle (1) and a cutting head (2) having a base plate (8), and several tubular cutting elements (10) inclined so that their cutting edges lie in inclined planes at an angle of 5° to 45° to a skin contact plane defined by the extremities of the cutting elements. The cutting elements can be arranged in an array of staggered rows.

Claims

1. A hand-held hard skin removing device for removing hard skin comprising a handle portion and a cutting head connected firmly to the handle portion to be moved across a skin surface thereby, the cutting head comprising a base, and at least two cutting elements projecting from the base and each defining a respective substantially annular cutting edge for contact with a skin surface to be treated, wherein the cutting elements are spaced apart from each other, and each cutting edge lies in a plane inclined to a skin contact plane containing the extremities of the cutting elements, wherein the base comprises a base plate having at least two sockets into which the cutting elements are disposed, and the axes of the sockets are parallel to each other and inclined with respect to a perpendicular to the plane of the base plate.

2. A hand-held device according to claim 1, wherein the inclined plane is at an angle in the range of from 5°

to 45°

to the skin contact plane.

3. A hand-held device according to claim 1, wherein the cutting elements are tubular.

4. A hand-held device according to claim 3, wherein the cutting elements are right circular cylindrical tubes, and the cutting edge of each cutting element lies in a plane perpendicular to the axis of the cutting element.

5. A hand-held device according to claim 1, wherein the cutting elements project from the base along parallel axes.

6. A hand-held device according to claim 1, wherein there are three or more cutting elements positioned in a staggered array.

7. A hand-held device according to claim 6, wherein the cutting elements are arranged in at least two rows extending transversely to a movement direction, the cutting elements in one row being staggered with respect to the cutting elements of another row.

8. A hand-held device according to claim 7, wherein there are at least eight cutting elements arranged in at least three rows.

9. A hand-held device according to claim 7, wherein a first row includes at least four cutting elements, a second row includes at least three cutting elements and a third row includes at least one cutting element.

10. A hand-held device according to claim 7, wherein the cutting elements of at least one row are spaced apart along a curved line.

11. A hand-held device according to claim 7, wherein the base has a front in proximity to the handle, and a rear distal the handle, the numbers of cutting elements in successive rows reducing from front to rear of the base.

12. A hand-held device according to claim 1, wherein the base comprises a base plate to which the cutting elements are fixed.

13. A hand-held device according to claim 12, wherein the base plate has sockets into which the respective cutting elements are inserted.

14. A hand-held device according to claim 13, wherein the sockets have inner ends that are open to a cavity within the device.

15. A hand-held device according to claim 14, wherein the cavity is open to the exterior of the device.

16. A hand-held device according to claim 15, wherein the cavity is formed by a lateral through opening in the device.

17. A hand-held device according to claim 1, wherein the handle portion is elongated.

18. A hand-held device according to claim 17, wherein the handle portion has an axis substantially parallel to a skin contact plane defined by the extremities of the cutting elements.

19. A hand-held device according to claim 1, wherein the inclined plane is at an angle in the range of from 10°

to 25°

to the skin contact plane.

20. A hand-held device to claim 1, wherein there are five or more cutting elements positioned in a staggered array.

21. A hand-held device according to claim 1, wherein the cutting elements are right circular cylindrical tubes having a diameter of 3 mm to 5 mm.
