Razors

Abstract

Razor handles are provided for razors having a battery-powered functionality. Methods of manufacturing such handles are also provided. In one implementation, the handle includes a unitary grip portion constructed to receive a razor head at one end thereof, and a battery cover, mounted on the grip portion. The grip portion and the battery cover, when joined, may together define a water-tight unit prior to mounting of the razor head on the grip portion.

1 . A razor handle for a wet razor having a battery-powered functionality, the handle comprising:
 a grip portion;   an actuator button, mounted on a receiving member sealingly mounted onto said grip portion to form a water-tight part with the grip portion and positioned to be depressed by a user of the razor said receiving member comprising a cantilever beam that carries an actuator member which transmits force from the actuator button to an underlying resilient membrane; and   an electronic switch, in electrical communication with the components, positioned to be actuated when the actuator is depressed.   
     
     
         2 . The razor handle of  claim 1 , further comprising a razor head attached to said grip portion. 
     
     
         3 . The razor handle of  claim 1 , further comprising a vibration motor contained within the handle. 
     
     
         4 . The razor handle of  claim 1 , within the grip portion is configured to provide the battery-powered functionality. 
     
     
         5 . The razor handle of  claim 1 , wherein the electronic switch requires an actuation force of at least 4 N applied over about a displacement of about 0.25 mm. 
     
     
         6 . The razor handle of  claim 1 , wherein the electronic switch makes an audible click when actuated. 
     
     
         7 . The razor handle of  claim 1 , wherein the grip portion includes a resilient membrane that is interposed between the actuator and the electronic switch. 
     
     
         8 . The razor handle of  claim 7 , wherein the resilient membrane is configured to exert a restoring force on the actuator after the actuator is depressed and released. 
     
     
         9 . The razor handle of  claim 1 , wherein the components include a printed circuit board, and the electronic switch is in communication with the printed circuit board and activates circuitry of the printed circuit board. 
     
     
         10 . The razor handle of  claim 1 , wherein the actuator comprises a button, and an upper surface of the button is substantially flush with an outer surface of the grip portion. 
     
     
         11 . The razor handle of  claim 1 , further comprising a closing system, including a first component within the battery cover, and a second component secured to the interior wall of the grip portion, the first component being configured to move axially within the battery cover during engagement of the battery cover with the grip portion, and being biased toward a predetermined axial position. 
     
     
         12 . The razor handle of  claim 10 , wherein the first and second components are configured to engage each other by rotation of the battery cover relative to the housing. 
     
     
         13 . The razor handle of  claim 10 , wherein the first component includes a spring element configured to apply an axial force between the grip portion and battery cover when the first and second components are engaged. 
     
     
         14 . The razor handle of  claim 10 , wherein engagement of the first and second components provides an electrical connection between the first and second components. 
     
     
         15 . The razor handle of  claim 1 , further comprising, within the grip tube, a pair of battery clamp fingers configured to exert a clamping force against the battery when the battery is in place in the razor. 
     
     
         16 . The razor handle of  claim 1 , wherein the grip tube includes a window, and the razor handle further includes an indicator positioned under the window. 
     
     
         17 . A razor handle comprising:
 a grip portion;   a razor head attached to said grip portion;   an actuator button, mounted on a receiving member sealingly mounted onto said grip portion to form a water-tight part with the grip portion and positioned to be depressed by a user of the razor said receiving member comprising a cantilever beam that carries an actuator member which transmits force from the actuator button to an underlying resilient membrane; and   an electronic switch, in electrical communication with the components, positioned to be actuated when the actuator is depressed.   
     
     
         18 . The razor handle of  claim 1 , further comprising a removable cartridge attached to said razor head.
