Abstract

An electric hair trimmer generally includes a handle, a drive system, and a cutter head. The cutter head includes a stationary blade and a movable blade, and the cutter head is releasably connectable to the handle in operative connection with the drive system. The handle is configured for ejecting the cutter head.

Claims (15)

1. An electric hair trimmer comprising:

a handle having a longitudinal axis;

a drive system;

a cutter head comprising a stationary blade and a movable blade, the cutter head being releasably connectable to the handle in operative connection with the drive system, said cutter head being slidable onto and off of the handle in a direction oblique to the longitudinal axis of the handle;

a slide that is displaceable relative to the handle to initiate ejection of the cutter head from the handle along said slidable direction of the cutter head; and

a resilient member facilitating ejection of the cutter head from the handle in the slidable direction of the cutter head.

2. The electric hair trimmer set forth in claim 1 wherein the cutter head further comprises:

a follower connected to the movable blade, wherein said follower is configured to be operatively connected to the drive system for oscillating the movable blade via the drive system; and

a tongue configured to provide clearance for the follower when the cutter head is ejected along said slidable direction obliquely relative to the longitudinal axis.

3. The electric hair trimmer set forth in claim 2 wherein the handle comprises a neck configured with an aperture that provides clearance for the follower when the cutter head is ejected obliquely relative to the longitudinal axis of the handle.

4. The electric hair trimmer set forth in claim 1 wherein the handle comprises said resilient member that is in the form of a spring, the slide being displaceable against the bias of the spring to initiate ejecting the cutter head.

5. The electric hair trimmer set forth in claim 1 wherein the handle further comprises a retaining recess, the cutter head further comprising a clip configured for insertion into the retaining recess upon sliding the cutter head onto the handle for releasable connection to the handle, and removal from the retaining recess when the cutter head is ejected from the handle.

6. The electric hair trimmer set forth in claim 5 wherein the clip is resiliently flexible to further facilitate ejecting the cutter head from the handle along the slidable direction of the cutter head.

7. The electric hair trimmer set forth in claim 6 wherein the handle comprises a channel having the retaining recess, the clip configured to slide along the channel for insertion into the retaining recess during connection of the cutter head to the handle.
