Cantilever comb guard
View Patent ↗A shaving blade assembly having a blade unit with at least one blade and a guard bar positioned in front of the blade. A cantilever guard is positioned in front of the blade unit defining a gap between the guard bar and the cantilever guard. The cantilever guard has a plurality of spaced apart fingers extending transverse to the blade. The fingers have a wedge shaped cross section in a direction transverse to the blades and are movable relative to the guard bar between a first position and a second position during a shaving stroke.
1. A shaving blade assembly comprising:
at least one blade having a cutting edge;
a blade unit dimensioned to receive the at least one blade; and
a cantilever guard positioned in front of the blade unit, the cantilever guard having a plurality of spaced apart wedge shaped fingers having a fixed end joined to the blade unit and a free end, wherein the fingers taper in a direction transverse to the cutting edge of the at least one blade from a greater thickness at the fixed end to a lesser thickness at the free end to facilitate movement of the fingers between a first position and a second position during a shaving stroke.
2. The shaving blade assembly of claim 1 wherein the fingers have a flat top surface and an angled bottom surface.
3. The shaving blade assembly of claim 2 wherein the top surface and the bottom surface define a taper angle of about 10 degrees to about 50 degrees.
4. The shaving blade assembly of claim 2 wherein the fingers comprise a resilient material having a Shore A hardness of about 20 to about 70.
5. The shaving blade assembly of claim 2 further comprising a gliding member positioned in front of the cantilever guard defining a gap between the cantilever guard and the gliding member that extends along a length of the cantilever guard.
6. The shaving blade assembly of claim 5 wherein the gliding member circumscribes the blade unit and delivers a shaving aid in front of and behind the blade unit.
7. The shaving blade assembly of claim 1 wherein the at least one blade with the cutting edge is a plurality of blades each having a cutting edge.
8. The shaving blade assembly of claim 7 further comprising a guard bar p 9 ositioned between the blades and the cantilever guard, the guard bar having a plurality of open slots that extend transverse to the blades.
9. The shaving blade assembly of claim 8 further comprising a handle mounted to the blade unit.
10. The shaving blade assembly of claim 8 wherein the guard bar is spaced apart from the cantilever guard by 0.5 mm to 2.5 mm
11. The shaving blade assembly of claim 7 further comprising a blade plane that is tangent to the cutting edges.
12. The shaving blade assembly of claim 11 wherein the fingers have a tip that is positioned below the blade plane.
13. The shaving blade assembly of claim 12 wherein each of the tips has a radius of about 0.15 mm to about 0.5 mm.
