Shaving Unit with Blade Cleaning Apparatus

Abstract

A shaving unit that includes a blade assembly, a handle assembly, and a push rod. The blade assembly includes a housing portion and two blades attached to interior walls of the housing portion. The blades being latitudinally aligned, longitudinally displaced, and having a spatial separation between the two blades. The handle assembly is attached to the housing portion of the blade assembly and includes an internal cavity. The shaving unit further includes a push rod positioned within the internal cavity of the handle assembly. The push rod includes a blunted end directly in contact with one of the two razor blades and an actuator button on an opposite end. The push rod is capable of being moved forward and backwards when actuated in either direction and when actuated in the forward direction causes the blade directly in contact with to increase the spacial separation between blades.

Claims

1. A shaving unit comprising: a blade assembly that includes a housing portion housing two blades, the housing portion including: a bottom surface section with an aperture that expose the two blades, the two blades longitudinally aligned and latitudinally displaced, and spatially separated; a sidewall section surrounding and continuing the bottom surface section; a top section surrounding and continuing the sidewall section; and the sections forming a hollow section where the two blades are fixed to an interior wall of the housing section; a handle assembly that includes an end section, and a sidewall section surrounding and continuing the end section forming an internal cavity, an opposite end of the sidewall section physically attachable with the housing portion, the sidewall section further including an aperture along a section of the sidewall portion; and a push rod positioned within the internal cavity of the handle assembly, the push rod including a blunted end directly in contact with one of the two razor blades and an actuator button on an opposite end, the actuator button positionable within the aperture opening along the sidewall portion of the handle assembly, the push rod capable of being moved forward and backwards when actuated in either direction and when actuated in the forward direction causes the blade directly in contact with to increase the spacial separation between blades.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0014] FIG. 1 is a bottom view of a shaving unit having two cutting units, according to an embodiment of the invention.

[0015] FIG. 2A is a top, cut away view of the shaving unit, according to an embodiment of the invention.

[0016] FIG. 2B is another top, cut away view of the shaving unit, according to an embodiment of the invention.

DETAILED DESCRIPTION

[0017] Referring to FIG. 1, shaving unit 10 represents a twin-blade shaving unit that includes a blade assembly 12, a handle assembly 14 attached thereto, and a first and second blade 16,18 housed within the housing assembly 12. The blades 16,18 are stacked in parallel may be longitudinally aligned but latitudinally displaced. Stated more simply, the one blade 18 may be advanced more forward than the other blade 16. Sectislmckinnon10@aol.comon 20 represents the space where debris from shaving may become lodged and need to be removed by the cleaning means described. The blade assembly 12 and handle assembly 14 may be made from plastic using traditional plastic injection molding techniques. The blade assembly 12 and handle assembly 14 may be attached together during the manufacturing process. The blade assembly 12 and handle assembly 14 are formed in such a way that the assembly 12,14 includes a hollow interior space to accommodate a push rod mechanism communicable coupled directly to one of the blades 16,18 so as to be able to manipulate the blade in a manner favorable to cleaning and dislodging the debris lodged within section 20. This aspect of the invention will be described in more detail in reference to FIGS. 2 and 3. The blades 16,18 may be made of a steel that is flexible and elastic enough so that the blade after being manipulated by the push rod will return to its original position, or close enough thereto, to result in normal operation.

[0018] Referring now to FIGS. 2A and 2B, illustrated is a top, cut away view of shaving unit 10 denoted generally as 50 and 80, respectively. Shaving unit 50,80 represents the twin-blade shaving unit 10 that includes the blade assembly 12, the handle assembly 14 attached thereto, first and second blade 16,18 housed within the housing assembly 12, and push rod 52 in its normal resting position. Shaving unit 80 represents the twin-blade shaving unit 10 with the push rod 52 in its extended position so to push the blade into a position that causes enough spatial separation between the blades so that debris can be removed from section 20. In each case, the push rod 52 is communicable coupled directly with the one of the blades.

[0019] The shaving unit 50,80 includes a base section 52 and an upstanding sidewall portion 54 continuing and surrounding the base section 52 to form a hollow cavity 56. The sidewall section 54 includes opening 55 along a surface of the sidewall section. This opening may also include an o-ring gasket, plastic or rubber, secured to an inner section of the cavity 56. The rim of the sidewall section 54 opposite the base section 52 maybe attached with blade assembly 12 along section 58. The blade assembly 12 also include an interior section essentially congruently aligned with the hollow cavity 56. The blade assembly further includes a bottom section 60 with an opening or aperture section that exposes the two blades 16,18, a side section 62 surrounding and continuing the bottom section to form the aforementioned interior section for receiving the push rod 52. The push rod 52 includes a push button 64 positioned within opening 55 and and attached rod 66 that can be moved in a forward direction, toward the blade and returned to its normal position using the push button 64. End 68 of push rod is a blunted end that can rest securely with one of the blades. To maintain stability of the push rod within the unit, the plastic or rubber o-ring may be used in combination with the rod to secure the push rod 52 into place. For example, along the aperture Due to the flexibility and resiliency of the steel used for the blade, the shaving unit 50 can be manufactured simply with minimal parts, keeping in line with traditional manufacturing techniques of simple, cheap, disposable razors. The push rod 52 is an effective, reliable, and cost effective method of keeping the shaving unit 50 clean so that may be usable for a longer period of time.

[0020] Thus, While there have been shown and described and pointed out fundamental novel features of the invention as applied to a preferred embodiment thereof, it Will be under stood that various omissions and substitutions and changes in the form and details of the devices illustrated, and in their operation, may be made by those skilled in the art Without departing from the spirit of the invention. For example, it is expressly intended that all combinations of those elements and/or method steps Which perform substantially the same function in substantially the same Way to achieve the same results are Within the scope of the invention. Substitutions of elements from one described embodiment to another are also fully intended and contemplated. It is also to be understood that the drawings are not necessarily drawn to scale but that they are merely conceptual in nature. It is the intention, therefore, to be limited only as indicated by the scope of the claims appended hereto.
