DETAILED DESCRIPTION OF THE INVENTION
[0021] FIGS. 1A and 1B are a front and side perspective view of a generic safety razor. Handle 1 shown in FIG. 1A demonstrates a relative orientation perpendicular to both blade unit 3 and razor blade(s) 2 as seen from either a front view or back view.
[0022] FIGS. 2A and 2B and 2C include perpendicular and non-perpendicular reference angles relative to handle angle. It is these two primary relative axes from a front or back perspective which define references to perpendicular and non-perpendicular in the embodiments to follow. Handle angle HA, perpendicular angle PA, and non-perpendicular angle NPA are seen in FIGS. 2A and 2B and 2C. These angles represent front and back view perspectives where handle angle HA remains constant on the one axis while the perpendicular angle PA and the non-perpendicular angle NPA are refer to side to side orientation relative the handle angle HA.
[0023] FIGS. 3A and 3B are front perspective views of safety razors which are embodiments of the present invention. In these two embodiments, the blade edge 2 is non-perpendicular to the handle axis. These designs are typical or disposable and replaceable cartridge razors where the blade unit 3 is substantially fixed to the handle unit and the blade unit 3 is not substantially adjustable to another angle orientation relative the handle angle HA seen in FIGS. 2A and 2B and 2C.
[0024] FIGS. 4A and 4B and 4C are front perspective views which explain adjustable function for one embodiment of the present safety razor invention. In this embodiment, blade unit 3 and connector 6 are able to pivot via mechanism 4 into multiple substantially non-moving substantially non-perpendicular positions as well as substantially non-moving per substantially perpendicular positions relative to handle angle HA to affect varied blade edge 2 angles for shaving.
[0025] FIGS. 5A and 5B and 5C and 5D are front perspective and exploded views which explain design conversion function using an adapter which is one embodiment of the present invention. FIG. 5A shows a standard razor handle 1 and a standard replaceable blade unit 3 attached. FIG. 5B shows and exploded view of FIG. 5A where the two components are separated. FIG. 5C shows a further exploded view which includes an adapter 7 which connects to both razor handle 1 and blade unit 3 to result in a new angle for blade edge 2 relative to handle angle HA of handle 1.
[0026] FIGS. 6A and 6B and 6C and 6D are front perspective and exploded views which explain design conversion function using an adapter which is one embodiment of the present invention. As with FIG. 5 above, FIG. 6A shows a standard razor handle 1 and a standard replaceable blade unit 3 attached. Razor handle 1 is connected to blade unit 3 via a connector 6. FIG. 6B shows and exploded view of FIG. 6A where the two components are separated. FIG. 6C shows a further exploded view which includes an adapter 7 which connects to both connector 6 and blade unit 3 to result in a new angle for blade edge 2 relative to handle angle HA of handle 1.
[0027] FIGS. 7A and 7B and 7C are front and back perspective views which explain design conversion function using a twist or inversion which is one embodiment of the present invention. In this embodiment, FIG. 7A depicts a twist of connector 6 which is connected to blade unit 3 of 180 degrees while holding handle 1 in place results in the view seen FIG. 7B which shows the back view of connector 6 and blade unit 3. FIG. 7C reflect turning the entire unit shown in FIG. 7B 180 degrees to reveal a front view where the blade edge 2 is set to a new angle relative to the handle angle HA and the blade edge 2 in FIG. 7A. The handle angle HA in both FIG. 7A and FIG. 7C are the same.
[0028] FIG. 8 includes front perspective and side views which explain design conversion function using a twist or inversion which is one embodiment of the present invention. In this embodiment, FIG. 8 depicts a twist of connector 6 which is connected to blade unit 3 of both 90 degrees and 180 degrees while holding handle 1 in place. This is a more detailed perspective of the embodiment seen in FIGS. 7A and 7B and 7C.
[0029] FIGS. 9A and 9B and 9C and 9D and 9E and 9F are front and back perspective views which explain design conversion function using a twist or inversion which is one embodiment of the present invention. Similar to the embodiment in FIGS. 7A and 7B and 7C and FIG. 8 except with this embodiment includes an additional connector 8. FIGS. 9A and 9B and 9C depict a sequence of movement by holding connector 8 and handle 1 while twisting connector 6 with blade unit 3 180 degrees to change the blade edge 2 angle from perpendicular angle PA to handle angle 1 to a non-perpendicular angle NPA to handle angle 1. FIGS. 9D and 9E and 9F depict a sequence of movement by holding handle 1 while twisting connector 8 with connector 6 with blade unit 3 180 degrees to change the blade edge 2 angle from perpendicular angle PA to handle angle 1 to a non-perpendicular angle NPA to handle angle 1.
[0030] FIGS. 10A and 10B and 10C are front perspective views which explain design conversion function using an integrated movement transfer mechanism which is one embodiment of the present invention. By rotating activator knob 9 in one radial direction in the opposite direction, an internal mechanism of position transfer mechanism 10 which attached to connector 6 is engaged to raise or lower one side of connector 6 thereby effecting an angle change for blade edge 2. knob 9 can position connector 6 and edge 2 into substantially perpendicular and substantially non-perpendicular angles. While these position are substantially fixed settings, the connector 6 can be fixed or flexible and function from a controllable bias angle which is either perpendicular angle PA or non-perpendicular angle NPA relative the handle angle HA.
[0031] FIG. 11 includes front perspectives which explain design conversion function and a locking mechanism which is one embodiment of the present invention. FIG. 11 depicts connector 6 with blade unit 3 moveable about pivot 4 relative to handle angle HA of handle 1. A sliding lock 11 is used in this embodiment to secure the angle of connector 6 whether connector 6 is a fixed angle or flexible angle connector. Sliding lock 11 secures the bias angle which is either perpendicular angle PA or non-perpendicular angle NPA relative the handle angle HA.
[0032] FIG. 12 includes front perspectives which explain design conversion function and a locking mechanism which is one embodiment of the present invention. FIG. 12 depicts connector 6 with blade unit 3 moveable about pivot 4 relative to handle angle HA of handle 1. A push lock 12 is used in this embodiment to secure the angle of connector 6 whether connector 6 is a fixed angle or flexible angle connector. Push lock 12 secures the bias angle which is either perpendicular angle PA or non-perpendicular angle NPA relative the handle angle HA.
