Embodiment Construction

[0031] refer to Figure 1-3 and 9-10, a blade set for electric hair clippers or hair clippers is generally designated 10 and includes a stationary blade 12 having a stationary blade body 14, at least one and preferably a pair mounted Aperture 16 , rear edge 18 and an opposing front edge 20 with a plurality of stationary blade teeth 22 . An upper surface 24 of the stationary blade opposes a user-accessible lower surface 26 of the clipper.

[0032] Also included in the blade set 10 is a moving blade 28 having a moving blade body 30 and having an upper surface 32 , an opposing lower surface 34 , a moving front edge 36 having a plurality of moving blade teeth 38 . As is well known in the art of hair clippers, the moving blade teeth 38 reciprocate laterally relative to the stationary blade teeth 22 to form cutting edges "E". After assembly, the lower surface 34 of the moving blade faces the upper surface 24 of the stationary blade 12 . Also included on the moving blade 28 is a r...

Abstract

A hair clipper blade set is provided comprising: a stationary blade having a front edge having a plurality of fixed teeth; and a moving blade including a moving front edge having a plurality of moving teeth, The moving teeth are arranged such that the moving blade teeth reciprocate laterally relative to the stationary blade teeth to form a cutting edge. A cam follower is provided on an upper surface of the moving blade and includes at least one cam follower structure constructed and arranged to guide the moving blade in reciprocation. A blade guide is located between the moving blade and the stationary blade and has at least one complementary blade guide formation configured to receive a corresponding said at least one cam follower formation for forming A plurality of contact points constructed and arranged to maintain alignment of the insert at the cutting edge.

Description

technical field [0001] The present application relates generally to electric hair clippers, and more particularly to a hair clipper blade set designed to support a moving blade in parallel alignment relative to a stationary blade during a reciprocating blade stroke. Background technique [0002] Electric hair clipper blade sets include moving blades that reciprocate sideways relative to stationary blades. The moving blade is connected to the motor drive shaft through an eccentric drive cam and a cam follower that converts the rotational motion of the motor drive shaft into the required linear reciprocating blade motion. A spring associated with the blade set applies a biasing force to force the moving blade against the stationary blade. If the moving blade deviates from a parallel travel relative to the stationary blade, the scalp of the target person being cut may be scored, or the hair cutting operation may be otherwise unsatisfactory. [0003] To address this problem, i...
