Razor docking and pivot
View Patent ↗A shaving razor system includes a razor handle that docks with a razor cartridge. The handle is configured to dock with the razor cartridge using a single hook configured to mate with a cartridge tab. A central pushrod is mounted with a spring into the handle, and is configured to exert a pushing force on the mounted cartridge. To eject the cartridge, the single hook may be pushed to pivot to the side of the cartridge tab, and thereby release the cartridge by ejecting it with a spring loaded pushrod.
1. A system comprising:
a razor cartridge with a front and a back, including a docking receiver on the back,
wherein the docking receiver includes two side walls and a single central tab, the single central tab located between the docking receiver side walls and the single central tab including a ramp; and
a razor handle with a back end and a docking end, the docking end including, a central pushrod, being slidably located in the handle;
a compression spring around the central pushrod, one end of the compression spring engaging the pushrod and another end of the compression spring being biased against a fixed portion of the handle to push the central pushrod toward the handle docking end and away from the handle back end; and
one central hook arm pivotally mounted to the central pushrod at an axis element, the axis element being between a hook end of the central hook arm and an extension end of the central hook arm, said extension end to be engaged to cause the hook end to disengage from the single central tab,
wherein the one central hook arm is configured to flex over the single central tab ramp and snap onto the single central tab, and
wherein the razor cartridge receiver side walls are configured to couple to the razor handle central pushrod.
2. The system of claim 1 wherein the central pushrod includes a barrel shaped end arranged perpendicularly to the central pushrod, the barrel shaped end configured to engage with the cartridge docking receiver, wherein the barrel shaped end includes an elongated axis perpendicular to the central pushrod.
3. The system of claim 2 wherein the pushrod barrel shaped end includes a recessed portion configured for the central hook arm hook end to fit near the pushrod barrel shaped end.
4. The system of claim 2 wherein the receiver walls are configured to receive the barrel shaped end of the pushrod.
5. The system of claim 1 wherein the cartridge receiver further includes a flat portion adjacent to the central tab, configured to allow the central hook arm to disengage the central tab by pivoting into the flat portion.
6. The system of claim 1 wherein the docking receiver walls are coated with a lubricious material.
7. The system of claim 1 further comprising, a slidable button connected to the handle, configured to slide toward the docking end.
8. The system of claim 7 wherein the slidable button includes a cam configured to contact with the pivot end of the hook arm when the slidable button is in the forward position, to pivot the hook arm in the handle.
9. The system of claim 1 wherein the razor cartridge further includes at least three razor blades, mounted in the razor cartridge.
