Abstract

The invention relates to a callus remover with a handle, a head piece (1) attached to the handle, and a fixing device (2) for mounting a blade (5) between the head piece and the fixing device, where the cutting edge of a blade fixed in its intended working position is preceded in the working direction by an area for contact with the body part of a user of the callus remover requiring treatment. To provide a callus remover that is particularly safe to use, and which additionally enables the most precisely defined possible removal of a callused skin layer, the callus remover is provided with a region preceding the blade that is designed as a pressure plate (13), the surface of which can be placed against the body part to be treated. The pressure plate can be of flat design and extend at least up to the cutting edge of the blade. The pressure plate can be limited on both sides by protrusions (16) and taper towards the cutting edge of the blade (FIG. 1a).

Claims

1. Callus remover with a handle, a head piece attached to the handle, and a fixing device for mounting a blade between the head piece and the fixing device, where the callus remover is provided with a contact surface which comes into contact with the body part requiring treatment and which, in the working direction, precedes the cutting edge of an associated blade that must be fixed in its intended working position, characterized in that the area preceding the blade is designed in the form of a pressure plate, the surface of which can be placed against the body part to be treated.

23. Callus remover according to claim 1, characterized in that the pressure plate is part of the head piece.

24. Callus remover according to claim 1, characterized in that the pressure plate extends up to the cutting edge of the blade in the working direction, at least over a partial area of the blade width, or it extends beyond the cutting edge towards the free end of the head piece.

25. Callus remover according to claim 24, characterized in that the area of the pressure plate extending over the blade is angled relative to the area preceding the blade in the working direction.

26. Callus remover according to claim 1, characterized in that the pressure plate is of flat design.

27. Callus remover according to claim 1, characterized in that, along the lateral limits of the blade working area, the pressure plate is spaced apart from the cutting edge in the working direction.

28. Callus remover according to claim 1, characterized in that the pressure plate has a ratio of width to length of less than or equal to 3:

1.

29. Callus remover according to claim 1, characterized in that the surface area of the pressure plate is ≧

approx. 30 mm².

30. Callus remover according to claim 1, characterized in that the pressure plate encloses an angle of approx. 3°

to 20°

with the longitudinal extension of the associated blade, at least at the level of the middle of the blade working area.

31. Callus remover according to claim 1, characterized in that the width of the pressure plate tapers towards the cutting edge of the blade.

32. Callus remover according to claim 1, characterized in that the pressure plate is limited on both sides over at least part of its length by protrusions extending essentially in the working direction.

33. Callus remover according to claim 1, characterized in that the pressure plate is limited by recesses on both sides in the area in front of the blade.

34. Callus remover according to claim 32, characterized in that the recesses are located at the level of the protrusions, between the protrusions and the blade.

35. Callus remover according to claim 1, characterized in that the side of the blade facing the surface to be treated is supported in the region of the cutting edge, at the level of the blade working area.

36. Callus remover according to claim 1, characterized in that the associated blade is curved transverse to the longitudinal direction of the callus remover and snapped onto the callus remover under pre-tension.

37. Callus remover according to claim 1, characterized in that the fixing device has tongues to the side of the pressure plate, which project in the direction of the handle and cover the associated blade on its lateral end regions.

38. Callus remover according to claim 1, characterized in that, to secure the fixing device, the head piece is provided with a tongue extending in the longitudinal direction of the handle, which engages a catch on the fixing device that passes through the blade, and in that the tongue has an incline for sliding the catch into its mounted position.

39. Callus remover according to claim 1, characterized in that, to secure the fixing device, the head piece is provided with a tongue extending in the longitudinal direction of the handle, which engages a catch on the fixing device that passes through the blade, and in that the tongue, on the blade or without the blade, is spaced apart from the fixing device by a distance that is less than the thickness of the blade.

40. Callus remover according to claim 39, characterized in that the tongue of the head piece contacts the blade on the side opposite the fixing device, in the region of the level of the blade'"'"'s contact with the fixing device, or in the region of the cutting edge.

41. Callus remover according to claim 1, characterized in that the fixing device, in the region of its end facing the cutting edge, provides a contact surface for the blade at the level of the lateral limits of the blade working area, or between them.

42. Callus remover according to claim 1, characterized in that the head piece has lateral guide areas angled against the surface to be treated, and in that the fixing device has guide surfaces on both sides for contacting the guide areas.

43. Callus remover according to claim 1, characterized in that the shape of the callus remover in the region of the pressure plate is dimensioned such that, if the blade working angle changes relative to its intended position by a value greater than or equal to 1 to 20°

, the blade no longer has shaving contact with the skin.
