Various advancements are disclosed herein, including without limitation accurate positioning of the blade relative to the rotary cutter, pivoting of a refill blade assembly 200 relative to a base portion 100 of the shaving apparatus to which it is coupled, and a connection between the refill blade assembly and the base portion of the shaving apparatus. Furthermore, a method of shaving is also disclosed.
Claims17
A shaving apparatus comprising:
- a rotary cutter comprising a plurality of cutting edges;
- a blade having a cutting edge, the blade mounted to a spring member, the blade biased into contact with the rotary cutter by the spring member;
- an electric motor operably coupled to a power source and the rotary cutter to rotate the rotary cutter about a rotational axis so that a user's hairs are sheared between the cutting edge of the blade and the cutting edges of the rotary cutter;
- and
- wherein the spring member comprises a cantilever, the blade mounted on the cantilever.
A refill blade assembly configured for detachable coupling to and from a shaving apparatus having a base portion, a rotary cutter having a plurality of cutting edges mounted to the base portion so as to be rotatable relative to the base portion about a rotational axis, and an electric motor operably coupled to a power source and the rotary cutter to rotate the rotary cutter about the rotational axis, the refill blade assembly comprising:
- a cover member;
- a spring member,
- a blade mounted to the spring member, the blade having a cutting edge;
- the spring member connected to the cover member so that the cutting edge of the blade at least partially defines a work window;
- the spring member is configured such that when the refill blade assembly is attached to the base portion, the blade is biased into contact with the rotary cutter by the spring member;
- and
- wherein the spring member comprises a cantilever, the blade mounted on the cantilever.
A refill blade assembly configured for detachable coupling to and from a shaving apparatus having a base portion, a rotary cutter having a plurality of cutting edges mounted to the base portion so as to be rotatable relative to the base portion about a rotational axis, and an electric motor operably coupled to a power source and the rotary cutter to rotate the rotary cutter about the rotational axis, the refill blade assembly comprising:
- a cover member;
- a spring member,
- a blade mounted to the spring member, the blade having a cutting edge;
- the spring member connected to the cover member so that the cutting edge of the blade at least partially defines a work window;
- the spring member is configured such that when the refill blade assembly is attached to the base portion, the blade is biased into contact with the rotary cutter by the spring member;
- wherein the spring member is integrally formed with the cover member;
- and
- wherein the spring member is defined by first and second notches that extend from the work window on opposite sides of the spring member.
