Patent Application
20090013534
The present invention relates to razors.
One difficulty in shaving is the constant need to clean a shaver's razor. The razor fills with shaving cream and hair after each stroke, leading to a substantially decreased rate of speed in shaving. It would therefore be desirable to increase the number of strokes that a shaver can complete before cleaning a razor is necessary.
A multiple face razor, including blade head, a plurality of blade faces attached to the blade head, and a razor handle attached to the blade head.
The following definitions are provided to aid in construing the claims of the present application:
Blade: A single razor blade.
Blade Face: One or more blades usable together in a single assembly such that all of the blades in the blade face are oriented in such a direction that they can contact a shaver's face (or other surface being shaved) simultaneously).
Razor Handle: The portion of the razor grasped by the user when shaving.
Blade Head: The Blade Face or Faces of a razor and the mounting to which they are attached, whether the mounting is in the form of a cylinder, a prism of any form, a square, a triangle, or otherwise.
Multiple Face Razor: A razor having more than one blade face, such that not all blade faces are used simultaneously.

Blade Head 120 is attached to Razor Handle 110 by wire mechanism 130, which is attached to Blade Head 120 at 140A and 140B and to Razor Handle 110 at 170. Wire mechanism 130 holds Blade Head 120 within it and a Blade Head can be changed by manually disengaging wire assembly 130, removing Blade Head 120, and replacing it with another Blade Head. Wire mechanism 130 is permanently attached to Razor Handle 110 at 170. Wire Mechanism 130 can be manufactured of metal, plastic, or any other strong, thin material, but typically, a relatively inflexible wire is utilized.
Button 150 is located on Razor Handle 110 and can be a button or other input device (such as a lever, toggle, or switch). Pressing on Button 150 causes Advancing Mechanism 160 to push on Blade Head 120, causing it to rotate one position. Advancing Mechanism 160 can be one or more rods, gears, springs, or other mechanical elements capable in combination of exerting sufficient force as a result of a single press of button 150 to advance Blade Head 120 by one position. Advancing Mechanism 160 is optionally battery powered.
In practice, a shaver initially utilizes Multiple Face Razor 100 in a manner identical to any standard razor. When the user needs to clean a Blade Face, however, the user presses Button 150, causing an additional, clean Blade Face to be brought into position for use. When all Blade Faces have been utilized, the user then cleans all of the Blade Faces simultaneously under a single stream of water. Thus, shaving time is considerably reduced.
In some embodiments, Advancing Mechanism 160 includes an advancing hook (not shown) and a series of notches, with one notch present on each Blade Face. In such embodiments, pressing on Button 150 causes the advancing hook to exert a rotational force on Blade Head 120 until the end of the advancing hook enters a notch at which time the advancing hook ceases moving and Blade Head 120 ceases rotating. In such embodiments, because the notches are evenly spaced one per Blade Face, Blade Head 120 rotates one Blade Face each time Button 150 is pressed. The advancing hook can be a wire hook, rod, or other advancing element and can also include one or more other mechanical elements, such as rods, gears, and springs, capable in combination of exerting sufficient force as a result of a single press of Button 150 to advance Blade Head 120 by one position. The advancing hook is optionally battery powered.

Blade Head 320 is attached to Razor Handle 310 by wire mechanism 330, which is attached to Blade Head 320 at 340A, 340B, and 340C and to Razor Handle 310 at 370. Wire mechanism 330 is attached to Razor Handle 310 at 370. Wire mechanism 330 can be manufactured of metal, plastic, or any other strong, thin material, but typically, a relatively inflexible wire is utilized. A Blade Head can be changed by detaching the wire assembly at 370.
Button 350 is located on Razor Handle 310 and can be a button or other input device (such as a lever, toggle, or switch). Pressing on button 350 causes advancing mechanism 360 to push on wire assembly 330, causing Blade Head 320 to rotate one position. Advancing mechanism 360 can be one or more rods, gears, springs, or other mechanical elements capable in combination of exerting sufficient force as a result of a single press of button 350 to advance Blade Head 320 by one position. Advancing mechanism 360 is optionally battery powered. Alternatively, button 350 and advancing mechanism 360 can be omitted and Blade Head 320 can be advanced manually.
