Detachable pivoting clipper blades

A hair clipper, comprising:

• a handle portion having a drive end with a first coupler formation;
• and
• a blade assembly including a housing at least partially enclosing a reciprocating blade and a fixed blade, and having a second coupler formation for engaging said first coupler formation, so that upon engagement of said first and second coupler formations form a ball-and-socket connection such that said blade assembly is both pivotable, to the extent that said blade assembly is movable up, down and to either side in varying degrees relative to said handle portion, and also is rotatable about said drive end;
• said handle portion includes a drive actuator member projecting from said drive end, and said blade assembly further includes a blade driver with a cam follower for engaging said drive actuator member, and a blade driving formation for engaging and moving said reciprocating blade, said drive actuator member passing through said connection to engage said blade driver.

A hair clipper, comprising:

• a handle portion having a drive end with a first coupler formation;
• a blade assembly including a housing at least partially enclosing a reciprocating blade and a fixed blade, and having a second coupler formation for engaging said first coupler formation to form a connection so that upon engagement, said blade assembly is pivotable and rotatable relative to said handle portion;
• and
• one of said first and second coupler formations being provided with biased release means for readily disengaging from the other of said first and second coupler formations, said biased release means being a component of said connection so that said connection is the point of disengagement of said coupler formations.

A disposable blade assembly for use with a hair clipper, the clipper including a handle with a drive end, a drive member extending from the drive end, and a coupler formation disposed at the drive end, said blade assembly comprising:

• a housing having a swivel formation configured for pivotally and rotatably engaging the coupler formation, said swivel formation defining a recess for accommodating the drive member;
• said housing also having blade locating means for locating a fixed blade thereon;
• a fixed cutting blade being configured for engagement on said blade locating means;
• a movable cutting blade being configured for reciprocal linear movement relative to said fixed cutting blade;
• and
• cam follower means for engaging said drive member through said recess in said swivel formation and for exerting a biasing force on said fixed and movable cutting blades.
