Abstract
A hair clipper includes a handle portion having a drive end with a first coupler formation, and a blade assembly. The blade assembly includes a housing at least partially enclosing a reciprocating blade and a fixed blade, and having a top, bottom, and at least two sides joining the top and bottom. Integrally joined to and extending away from the bottom of the housing is a second coupler formation for engaging the first coupler formation. The first and second coupler formations form a releasable connection which inhibits movement of the blade assembly with respect to the handle portion when the two coupler formations are engaged.
Claims24
A hair clipper, comprising:
- a handle portion having a drive end including a first coupler formation;
- a blade assembly including a housing at least partially enclosing a reciprocating blade and a fixed blade, said housing having a top portion, a bottom portion, and at least two side portions connecting said top and bottom portions;
- and
- a second coupler formation for engaging said first coupler formation,
- wherein said second coupler formation integrally joins to and extends away from said bottom portion of said blade assembly housing,
- wherein said first and second coupler formations form a releasable connection, and
- wherein said releasable connection inhibits movement of said blade assembly with respect to said handle portion upon engagement of said first and second coupler formations.
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 to form a releasable connection which restricts movement of said blade assembly relative to said handle portion when said first and second coupler formations are engaged, and
- said releasable connection prevents physical contact between said handle portion and said housing of said blade assembly when engaged.
A disposable blade assembly for use with a hair clipper, the clipper including a handle having a drive end, a drive member extending from the drive end, and a coupler formation disposed at the drive end, the disposable blade assembly comprising:
- a housing having a top portion, a bottom portion, and at least two side portions joining said top and bottom portions;
- blade locating means disposed on an interior of said top portion;
- 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;
- a shroud formation defining a recess for accommodating the drive member, said recess having a first opening integrally connected to a central opening in said housing bottom portion, and a second opening opposed to said first opening, said second opening for engaging the coupler formation of the drive member;
- and
- cam follower means for engaging said drive member through said first opening in said shroud formation and for exerting a biasing force on said fixed and movable cutting blades,
- said recess having an irregular shape which restricts movement of the engaged coupler formation.
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, said first and second coupler formations forming a connection which restricts movement of said blade assembly relative to said handle portion upon engagement;
- at least one of said first and second coupler formations is provided with release means for readily disengaging from the other of said first and second coupler formations, said release means including a tab projecting from said at least one coupler formation for facilitating one-handed release by a user.
