US 12,611,790 B1 · Rotating shaving razor apparatus

Abstract

A shaving razor apparatus having a handle with a blade-carrying head at one end and a rotary assembly at the opposite end. The rotary assembly enables controlled pivoting of the handle and head in response to pressure. It includes a pivot rod retained transversely within a channel in the handle, along with securing members and grip portions that stabilize and assist manual adjustment. A spring biasing member provides rotational resistance and recoil bias during use. In the primary embodiment, the spring comprises a torsion coil and extended arm retained under preload tension by a catch at the distal end of the handle. Alternative embodiments may utilize elastic springs or leverage gravitational force to achieve similar biasing effects. The design enables ergonomic control and dynamic blade positioning, with modular components that allow for varied resistance profiles and interchangeable biasing elements.

Dependent claims

A rotating shaving razor apparatus comprising:

a handle having a proximal end and a distal end;
a blade-carrying head disposed at the distal end of the handle;
a rotary assembly positioned at the proximal end of the handle for elevation and depression of the handle and the blade-carrying head, wherein the rotary assembly includes a pivot rod having a first lateral end, a second lateral end, and a medial section, the medial section being retained within a channel in the handle in a transverse orientation relative to a rotational longitudinal axis of the handle, thereby defining a pivot axis about which the handle rotates;
and a biasing member connected to the rotary assembly and longitudinally connected to the distal end of the handle to bias the handle from a neutral position to a shaving position.

A rotating shaving razor apparatus comprising:

a handle having a proximal end and a distal end;
a blade-carrying head disposed at the distal end of the handle;
a rotary assembly positioned at the proximal end of the handle for biasing elevation and depression of the handle and the blade-carrying head, the rotary assembly including:
a pivot rod extending transversely through a channel in the handle, the pivot rod having a first lateral end, a second lateral end, and a medial section, the medial section being retained within the channel in the handle in a transverse orientation relative to a rotational longitudinal axis of the handle, thereby defining a pivot axis about which the handle rotates;
a first securing member attached to the first lateral end of the pivot rod and a second securing member attached to the second lateral end of the pivot rod;
an elastic biasing member extending from the first securing member to the second securing member, the elastic biasing member being looped over a post disposed at the distal end of the handle, wherein the elastic biasing member provides resistance during elevation and depression of the blade-carrying head.
