Abstract: A blade cap is provided to shield a user from heat generated by operation of a blade assembly. The blade cap provides an insulative barrier between the blade assembly and the skin of the user. The blade cap may prevent discomfort or burns from the heat generated by the blade assembly. The blade cap includes openings, channels, projections, tabs, and other formations to allow the flow of air through the passageways between the blade cap and the blade.

Abstract: A drive cap uses snap fasteners to couple with the housing assembly of a hair clipper. The drive cap uses joining structures, such as protrusions and recesses, to align with the upper and lower housings of the housing assembly. Once correctly aligned, snap fasteners enable a snug fit and enhance the fit and finish of the hair clipper. The snap fasteners can be located on an inner surface of the drive cap, lower housing, and/or upper housing. A snap detent is located on the inner surface of an adjacent surface to receive the snap fastener. Using a combination of protrusions, extensions, voids, and recesses, in addition to the snap fasteners ensures a secure fit for the drive cap between the upper and lower housings. The snap fasteners couple the drive cap to upper and lower housings seamlessly along the outer surface of the hair clipper and facilitate quick release of the drive cap for maintenance or cleaning.

Abstract: A pad assembly is described that retains a blade assembly or set to the body of a hair cutter. The pad assembly reduces random forces generated by the blade assembly and ensures an accurate and repeatable tension is maintained between the inner and outer blades of the blade assembly. The pad assembly acts as an intermediary between the blade assembly and the body of the hair clippers to reduce challenges associated with fasteners directly attaching the blade assembly to the body of the clipper.

Abstract: A haircutter handle has upper and lower housings. The upper housing and lower housing join to form a circumvoluted and/or spiraled exterior surface. The handle narrows and extends axially from a blade end to a handle or gripping end. The blade has an upper blade that oscillates over the lower blade to cut hair. The handle has a reduction taper that facilitates gripping and/or handling the handle. The taper also orients the motor and battery so that the center of gravity is positioned within the palm of the user's hand when gripping the handle. The blade end of the handle has a width and/or height that are greater than a width and/or height at the handle end. The reduction in height and/or width dimensions define a taper. In some embodiments, the width tapers more than the height tapers to facilitate gripping the handle about the center of gravity.

Abstract: A blade assembly for a hair cutting apparatus includes a first blade having teeth extending along a first blade edge, and a second blade having teeth extending along a second blade edge. A distance between the first and second blade edges defines a blade gap. A yoke is coupled to the second blade and configured to convert motion of a drive into reciprocation of the second blade relative to the first blade to cut hair. A spring includes a spring base and at least one spring arm configured to reciprocate with the second blade. A guide assembly includes a guide and a spring retainer, the guide being positioned between the first blade and the second blade, and the spring retainer fixing the spring base relative to the first blade, wherein in response to moving the guide relative to the first blade, the blade gap changes.

Abstract: A hair clipper or cutter is provided with an adjustment slider that adjusts the gap between an inner and outer blade. A yoke is attached to the inner blade. The adjustment slider may be configured with preset gap lengths and may be adjustable before, after, or during a hair cutting operation. A T-guide couples the adjustment slider to the inner blade to slidably move the inner blade relative to the outer blade. The yoke, inner blade, outer blade and/or T-guide may be magnetized to create an attractive or repulsive force between the inner blade and the outer blade.
