Shaving razor with one or more reciprocating blades

Abstract

A shaving razor having a handle and a shaving head with an exposed reciprocating blade. A power source is disposed within the handle with an actuator that causes at least one blade of a multi-blade razor head to reciprocate within a zone of motion. Other embodiments are also described and claimed.

What is claimed is: 
     
       1. A shaving razor comprising:
 a handle; 
 a power source residing within the handle; 
 a shaving head containing at least two razor blade assemblies, each of the blade assemblies include blades which at least one blade each having a cutting edge, wherein the cutting edges of the blade assemblies reside in a single cutting plane, at least a first of the blade assemblies is moveably coupled within the shaving head so that the first blade assembly can be driven to translate laterally within a zone of motion; and 
 an actuator coupled to the power source, the actuator to apply a force that drives the first blade assembly to reciprocate within the zone of motion to translate relative to an adjacent one of the blade assemblies. 
 
     
     
       2. The shaving razor of  claim 1  where in wherein the actuator comprises:
 one of an electric motor, a piezo electric motor or a servo. 
 
     
     
       3. The shaving razor of  claim 1  wherein the force applied by the actuator is a magnetic force to drive the first blade assembly. 
     
     
       4. The shaving razor of  claim 1  wherein the force applied by the actuator is a mechanical force to drive the first blade assembly. 
     
     
       5. The shaving razor of  claim 1  wherein the zone of motion is defined to be in the range of 0.1 mm to 0.5 mm relative to the adjacent blade assembly. 
     
     
       6. The shaving razor of  claim 1  wherein the actuator comprises:
 a magnetic actuator. 
 
     
     
       7. The shaving razor of  claim 6  further comprising:
 a magnetic mass coupled to the first blade assembly and driven by the magnetic actuator. 
 
     
     
       8. The shaving razor of  claim 1  further comprising a second blade assembly that is moveably coupled to the razor shaving head so as to translate within a second zone of motion via a force applied by the actuator and wherein the first and second blade assemblies translate in opposite directions within their respective zones of motion, wherein the second blade assembly is one of the at least two blade assemblies. 
     
     
       9. The shaving razor of  claim 8  wherein each of the zones of motion are defined to be in a range of 0.1 mm to 0.5 mm relative to at least the adjacent blade assembly. 
     
     
       10. The shaving razor of  claim 8  wherein the actuator applies a magnetic force to drive the first and second blade assemblies. 
     
     
       11. The shaving razor of  claim 8  wherein the first and second blade assemblies are adjacent to each other within the shaving head. 
     
     
       12. The shaving razor of claim 1 wherein a second of the blade assemblies is moveably coupled within the shaving head so that the second blade assembly can be driven to translate laterally within a second zone of motion.  
     
     
       13. A shaving razor comprising:
 a handle;   a shaving head containing at least two razor blade assemblies, each of the blade assemblies include at least one blade, each of a first blade assembly and a second blade assembly of the at least two blade assemblies are moveably coupled within the shaving head so that the first blade assembly can be driven to translate laterally within a first zone of motion and the second blade assembly can be driven to translate in a second zone of motion; and   one or more actuators coupled to, in use, receive power from a power source, the actuators to apply a force that drives the first blade assembly to reciprocate within the first zone of motion and the second blade assembly to reciprocate within the second zone of motion, wherein the translation of the first blade assembly is in an opposite direction relative to the translation of the second blade assembly, and   wherein a first blade in the first blade assembly and a second blade in the second blade assembly are ones of the at least one blade and each have a single substantially straight cutting edge.    
     
     
       14. The shaving razor of claim 13 wherein each of the zones of motion are defined to be in a range of 0.1 mm to 0.5 mm relative to each other.  
     
     
       15. The shaving razor of claim 13 wherein the first and second blade assemblies are adjacent to each other within the shaving head.
