Comb support and release mechanism for electric dry shaver

Claim 2

A shearing head for an electric dry shaver comprising an inner head frame and an outer head frame secured together to form a head assembly, a foraminous shearing member hingeably supported on said head assembly, at least one cutter means mounted on said head assembly for movement in shearing engagement with said foraminous member, said outer head frame having spaced end walls forming with said inner head frame a recess within which said cutter means is mounted, means biAsing said foraminous member from a closed position seated against said outer head frame closing said recess toward an open position in which said foraminous member is spaced away from said cutter means, latch means slidably mounted in said inner head frame and having manually actuable means extending outwardly of said outer head frame so that it may be finger actuated, said latch means including a latch retainer adapted to lock said foraminous member in said closed position, said latch retainer being disengaged from locking engagement with said foraminous member upon actuation of said latch means, said latch means including a slidably mounted latch member received in an upwardly facing groove in said inner head frame, spring means received in said groove and biasing said latch member to one end of said groove, a latch assembly plate overlying said groove to hold said spring and latch member in assembled position on said inner head frame, said assembly plate being gripped between said inner and outer head frames, said latch retainer being formed on said latch member and comprising an L-shaped projection which extends into locking engagement with said foraminous member.

Claim 3

The shearing head of claim 1 including supporting means which hingeably support said foraminous member with respect to said head assembly, said assembly plate being formed with an unsupported edge portion which clamps the edge of said supporting means against said head assembly to provide the hingeable support means for said foraminous member whereby said foraminous member may move from its closed position to an open cleaning position when said manually actuable means is depressed.

Claim 4

A shearing head for an electric shaver as set forth in claim 1 wherein said cutter means comprises a pair of cutter carrying shafts, said shafts having mounted thereon radially directed cutters which engage the underside of said foraminous member when said member is in said closed position, said shafts being supported for oscillation in spaced bearings which are mounted between wall portions of said inner head frame and said outer head frame, said latch assembly plate being positioned beneath said cutter supporting shafts and being substantially coextensive with said inner head frame.

Claim 5

An electric dry shaver comprising a frame supporting an arched perforated comb, movable cutter means supported by said frame for shearing engagement with the underside of said comb, said cutter means being supported in a recessed portion of said frame, said arched comb overlying said recess and forming a compartment for receiving and storing hair clippings, a hinge plate for movably mounting said comb with respect to said frame, said hinge plate being pivoted for limited movement at one edge to said frame and pivoted for limited movement at the opposite edge to said comb, spring biasing means operating on said hinge plate and said comb to bias said comb with respect to said hinge plate to the limit of its movement in one direction, said hinge plate and said comb being movable to a locked position in opposition to said biasing means, said hinge plate and comb holding said biasing means in a deflected stressed condition when in said locked position, said hinge plate and said comb in said locked position closing said hair clipping receiving recess, spring operated latch means for retaining said hinge plate and said comb in said locked position, said latch means comprising a latch member slidably mounted on said frame and having a manually actuable means extending beyond said frame and having a latch retainer which engages said comb to retain said comb and said hinge plate in said locked position, spring means biasing said latching member to a position in which said latch retainer is engaged with said comb, said latch member being slidable in opposition to said spring biasing means to disengage said latch retainer from said comb whereby said biasing means operating between said hinge plate and said comb moves said comb from said locked positioN, said latch member being slidably received in an outwardly facing channel in said frame, and a plate member overlying said channel to retain said latch means and extending into engagement with said hinge plate to pivotally support said hinge plate with respect to said frame.

Claim 6

An electric dry shaver comprising a frame supporting an arched perforated comb, movable cutter means supported by said frame for shearing engagement with the underside of said comb, said cutter means being supported in a recessed portion of said frame, said arched comb overlying said recess and forming a compartment for receiving and storing hair clippings, a hinge plate for movably mounting said comb with respect to said frame, said hinge plate being pivoted for limited movement at one edge to said frame and pivoted for limited movement at the opposite edge to said comb, spring biasing means operating on said hinge plate and said comb to bias said comb with respect to said hinge plate to the limit of its movement in one direction, said hinge plate and said comb being movable to a locked position in opposition to said biasing means, said hinge plate and comb holding said biasing means in a deflected stressed condition when in said locked position, said hinge plate and said comb in said locked position closing said hair clipping receiving recess, spring operated latch means for retaining said hinge plate and said comb in said locked position, said latch means comprising a latch member slidably mounted on said frame and having a manually actuable means extending beyond said frame and having a latch retainer which engages said comb to retain said comb and said hinge plate in said locked position, spring means biasing said latching member to a position in which said latch retainer is engaged with said comb, said latch member being slidable in opposition to said spring biasing means to disengage said latch retainer from said comb whereby said biasing means operating between said hinge plate and said comb moves said comb from said locked positioN, said latch member being slidably received in an outwardly facing channel in said frame, and a plate member overlying said channel to retain said latch means and extending into engagement with said hinge plate to pivotally support said hinge plate with respect to said frame.

Claim 7

The electric dry shaver set forth in claim 4 having a cup-shaped housing including an opening within which said frame is mounted, a motor secured to said frame on the side thereof within said shaver housing, drive means extending from said motor into driving engagement with said cutter means, said frame having an opening through which said drive means extends from said motor enclosure into engagement with said cutter means, a channel formed in said frame on the side thereof opposite from the side mounting said motor, said latch means being slidably positioned within said channel.
