Hair trimmer and deshedder for pets

A method of operating a hair grooming device having a longitudinal axis, the method comprising:

• providing the hair grooming device, the hair grooming device comprising
• a handle, the handle having a longitudinal length which extends along the longitudinal axis;
• a plurality of blades, the plurality of blades each having a longitudinal length which extends along the longitudinal axis, and the plurality of blades each having a plurality of teeth and a plurality of hair receiving openings arranged along the longitudinal length of the blade in alternating succession, respectively;
• wherein the plurality of blades comprise a movable blade which is movable along the longitudinal axis relative to a second blade of the plurality of blades;
• wherein the plurality of teeth of the movable blade are movable relative to the plurality of hair receiving openings of the second blade such that each of the plurality of hair receiving openings of the second blade are at least partially laterally coverable at a first side of the second blade by one of the plurality of teeth of the movable blade, respectively, as the movable blade is moved along the longitudinal axis relative to the second blade;
• and
• moving the movable blade relative to the second blade such that each of the plurality of hair receiving openings of the second blade are at least partially laterally covered at a first side of the second blade by one of the plurality of teeth of the movable blade, respectively, by pressing a push-button actuator to move the movable blade distally along the longitudinal axis;
• wherein the push-button actuator is disposed at a first side of the handle;
• wherein the push-button actuator is coupled to an elastically deformable mechanical linkage such that, upon pressing the push-button actuator, the elastically deformable mechanical linkage deforms to move the movable blade distally along the longitudinal axis.

A hair grooming device having a longitudinal axis, the hair grooming device comprising:

• a handle, the handle having a longitudinal length which extends along the longitudinal axis;
• a plurality of blades, the plurality of blades each having a longitudinal length which extends along the longitudinal axis, and the plurality of blades each having a plurality of teeth and a plurality of hair receiving openings arranged along the longitudinal length of the blade in alternating succession, respectively;
• wherein the plurality of blades comprise a movable blade which is movable along the longitudinal axis relative to a second blade of the plurality of blades;
• wherein the plurality of teeth of the movable blade are movable relative to the plurality of hair receiving openings of the second blade such that each of the plurality of hair receiving openings of the second blade are at least partially laterally coverable at a first side of the second blade by one of the plurality of teeth of the movable blade, respectively, as the movable blade is moved along the longitudinal axis relative to the second blade;
• wherein the plurality of blades further comprise an additional movable blade which is movable along the longitudinal axis relative to the second blade of the plurality of blades;
• wherein the additional movable blade has a longitudinal length which extends along the longitudinal axis, and a plurality of teeth and a plurality of hair receiving openings arranged along the longitudinal length in alternating succession;
• wherein the plurality of teeth of the additional movable blade are movable relative to the plurality of hair receiving openings of the second blade such that each of the plurality of hair receiving openings of the second blade are at least partially laterally coverable at a second side of the second blade opposite the first side of the second blade by one of the plurality of teeth of the additional movable blade, respectively, as the additional movable blade is moved along the longitudinal axis relative to the second blade.
