Abstract

Abstract A shaving apparatus is provided with a shear plate having hair-entry apertures and formed with an inner surface, and a cutting unit associated with and drivable relative to the shear plate. The cutting unit comprises cutting elements extending towards the shear plate, each cutting element having an end surface facing the inner surface of the shear plate and being formed with a cutting edge, and hair-pulling elements respectively associated with the cutting elements and positioned in front of the cutting elements in the direction of driving, each hair-cutting element being rigidly connected to its associated cutting element and having a first end surface portion facing the inner surface of the shear plate and being formed with a contact edge. Each contact edge is situated at a greater distance than its associated cutting edge from the inner surface of the shear plate. Each hair-pulling element also has a second end surface portion adjoining the first end surface portion but situated at a greater distance than the first end surface portion from the inner surface of the shear plate to thereby provide a recess between the end surface of each cutting element and the first end surface portion of its associated hair-pulling element.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 275 words
A shaving apparatus having a shear plate provided with hair-entry apertures and formed with an inner surface, and a cutting unit associated with and drivable relative to the shear plate; said cutting unit comprising cutting elements extending towards the shear plate, each cutting element having an end surface facing the inner surface of the shear plate and being formed with a cutting edge, and hair-pulling elements respectively associated with the cutting elements and positioned in front of said cutting elements in the direction of driving, each hair-pulling element being rigidly connected to its associated cutting element and having a first end surface portion facing the inner surface of the shear plate and being formed with a contact edge, said first end surface portion of each hair-pulling element being situated at a greater distance than the end surface of its associated cutting element from the inner surface of the shear plate, each hair-pulling element also having a second end surface portion adjoining said first end surface portion but situated at a greater distance than said first end surface portion from the inner surface of the shear plate to thereby provide a recess between the end surface of each cutting element and the first end surface portion of its associated hair-pulling element, the first and second end surface portions of each hair-pulling element and the end surface of its associated cutting element extending respectively in planes substantially parallel to the plane of the inner surface of the shear plate, and each hair-pulling element further having a front surface in the direction of driving, said front surface extending substantially perpendicularly to the inner surface of the shear plate.
Claim 2
Dependent Claim 275 words
A shaving apparatus having a shear plate provided with hair-entry apertures and formed with an inner surface, and a cutting unit associated with and drivable relative to the shear plate; said cutting unit comprising cutting elements extending towards the shear plate, each cutting element having an end surface facing the inner surface of the shear plate and being formed with a cutting edge, and hair-pulling elements respectively associated with the cutting elements and positioned in front of said cutting elements in the direction of driving, each hair-pulling element being rigidly connected to its associated cutting element and having a first end surface portion facing the inner surface of the shear plate and being formed with a contact edge, said first end surface portion of each hair-pulling element being situated at a greater distance than the end surface of its associated cutting element from the inner surface of the shear plate, each hair-pulling element also having a second end surface portion adjoining said first end surface portion but situated at a greater distance than said first end surface portion from the inner surface of the shear plate to thereby provide a recess between the end surface of each cutting element and the first end surface portion of its associated hair-pulling element, the first and second end surface portions of each hair-pulling element and the end surface of its associated cutting element extending respectively in planes substantially parallel to the plane of the inner surface of the shear plate, and each hair-pulling element further having a front surface in the direction of driving, said front surface extending substantially perpendicularly to the inner surface of the shear plate.
