Callus remover

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. 1 a ).

       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.
