DETAILED DESCRIPTION OF THE INVENTION
Referring to FIGS. 1-3, shaving razor 10 includes a housing or cartridge 12 detachably joined to handle 14. The housing 12 includes one or more first blades 17 mounted in housing 12 and a separate second or trimmer blade 19 mounted in housing 12. The blades 17 and 19 are held in the housing 12 by metal clips 21. The first blades 17 have substantially parallel sharp cutting edges 18 and extend in a first direction. The second or trimming blade 19 has a sharp cutting edge 20 that extends in a second direction different from the first direction. The first blades 17 have their cutting edges 18 on the first side 23 of housing 12 whereas the second blade 19 has its cutting edge 20 on the opposite second side 25 of housing 12.
Referring now to FIG. 2, a guard structure 30 is provided on housing 12 for contacting the skin in front of blades 17 and a cap structure 34 is provided on housing 12 for contacting the skin behind blades 17 during the shaving stroke. The guard structure 30 may comprise an elastomeric material. The cap structure 34 may comprise a lubricating strip.
Referring now to FIG. 3, a guard structure 40 is provided on the housing 12 for contacting the skin in front of blade 19 and a cap structure 44 is provided on housing 12 for contacting the skin behind blade 19 during the shaving stroke. The guard structure 40 may comprise an elastomeric material. The cap structure 44 may comprise a lubricating strip.
Referring now to FIG. 1, housing 12 is pivotally joined on a yoke member 50 having a pair of arms 52 which extend from a hub 35 and are journalled in opposite ends of housing 12 so that housing 12 can pivot relative to handle 14 about an axis substantially parallel to the blade edges. Hub 35 selectively attaches to and detaches from handle 13. Any known hub can be utilized. In this embodiment release button 36 cooperates with hub 335 such that when release button 36 is pressed inward, hub 35 is disengaged from handle 13.
Referring now to FIG. 4, shaving razor 10 is held in a position such that trimming blade 19 (not shown) is in contact with user's skin 70. Trimming blade 19 is not shown as it is concealed from view by housing 12 when viewed from this angle. To enable the user to accurately align the trimming blade edge of the trimming blade on the user's skin, the housing 12 is provided with a trimming blade alignment member 60. The trimming blade alignment member 60 is provided on the side surface 62 of housing 12. An identical blade alignment member is provided on the opposite side surface 64 (not shown in FIG. 4.) The trimming blade alignment member 60 indicates the position of trimming blade 19 and trimming blade edge 20. The trimming blade alignment member 60 indicates the position of trimming blade 19 and trimming blade edge 20 by providing a visual indication on housing 12. When shaving the face a user can readily see the alignment member 60 with the aid of a mirror and can accurately position the trimming blade edge 20 on the intended location to enable accurate shaving.
As seen in FIG. 4, the alignment member 60 is a linear marking on the housing 12. The alignment member 60 is provided on the side surface 62 of housing 12. In addition to aligning the trimming blade edge accurately on the user skin, the alignment member 60 also indicates the angle at which the housing is to be held relative to the user's skin 70. In FIG. 4, the alignment member 60 is positioned on housing 12 to be held substantially perpendicular to the user's skin 70, or substantially at a 90° angle to the user's skin 70.
The alignment member 60 may be a first color and the housing 12 may be a second color different from the first color. For example, the alignment member may be orange and the housing blue. Alternatively, the alignment member may be a first shade of orange such as dark orange, and the housing may be a lighter shade of orange.
The alignment member 60 may be printed or painted on the housing 12. The alignment member 60 may be incorporated into the original mold to make housing 12. The alignment member 60 may be a sticker which is applied to housing 12. The alignment member 60 may be a separate member that is secured to housing 12. For example, the separate member may be metal, plastic or rubber that is secured to housing 12 by any conventional means.
Referring now to FIGS. 5 and 6, there is shown a housing 12 having an alignment member 60 on side surfaces 62 and 64. Each alignment member 60 is a recess in housing 12. As seen in FIG. 6, the upper portion of the recess of alignment member 60 aligns with the blade edge 20 of trimmer blade 19. Housing 12 has a guard structure 40 before blade 19 and a cap structure 44 after blade 19.
Referring now to FIGS. 7 and 8, there is shown a housing 12 having an alignment member 60 on side surfaces 62 and 64. Each alignment member 60 is a protrusion extending outward from housing 12. As seen in FIG. 8, the upper portion of the protrusion of alignment member 60 aligns with the blade edge 20 of trimmer blade 19. Housing 12 has a guard structure 40 before blade 19 and a cap structure after blade 19.
The alignment member 60 may be a high illumination element such reflective material. The alignment member 60 may be a luminescent marking on the housing. The alignment member 60 may be an electrically activated component such as a light emitting diode.
Referring now to FIG. 9, housing 12 has a skin contact surface or guard 40 which contacts the skin 70 before blade edge 20 of trimming blade 19. A skin contact surface or cap 44 contacts the skin behind blade edge 20 of trimming blade 19. Skin contact surfaces 40 and 44 are provided on the housing for contact with the skin in front of and behind the blade edge 20 of blade 19 during the performance of a shaving stroke. The alignment member 60 which is a linear marking on side edge 62 of housing 12 extends substantially perpendicular to a plane 65 tangential to the skin contact surfaces 40 and 44 and substantially intersects the blade edge 20 position projected longitudinally of the blade edge.
