A hair trimmer includes a cutting head and a body configured for easy reach of the hard to reach places, such as behind ears. This is achieved by shaping a front portion of the body to have cutouts behind the cutting head, which allow the trimmer to navigate around parts such as an ear. The cutouts also improve air flow around the front of the trimmer's body, thereby improving performance and durability of internal trimmer components through better cooling. The walls of the cutouts may have air ducts to further improve the cooling of the internal components. The cutouts also reduce the vibration of the cutting head and the body, leading to better trimming experience for the user and to improved durability of the trimmer. The method of using a trimmer with a cutting head and a body configured for easy reach of hard to reach places, such as behind ears, is also described.

A multi-cutting element shaving device is disclosed. The device comprises a handle and a head portion comprising at least two cutting assemblies, which are mounted in parallel, to one another on a frame of the head portion. The cutting assemblies include each a cylindrical screen and a blade housed in the cylindrical screen. Each of said cylindrical screens is rotatable about a respective longitudinal symmetry axis thereof, and the rotation of each cylindrical screens is manually effected by translating the head portion along a surface with the cylindrical screen contacting the surface so that substantially no sliding, of the cylindrical screens occurs as the head portion is translated against the surface. The head portion mounting angle relative to the handle is changeable during use of the shaving device such that both cylindrical screens are simultaneously maintained in contact with the surface, which is being shaved.

A pet hair trim clipper includes a main clipper body and a handle connected to the main clipper body, wherein the main clipper body includes at least one longitudinal trim cutter for trimming the pet hair and a hair removing element for scraping down the hair on the longitudinal trim cutter, wherein a trimming direction of the longitudinal trim cutter is perpendicular to a longitudinal direction of the handle, so as to facilitate the use.

A dual reciprocating blade landscape saw is operably connected to a rotatable shaft of an input device. The landscape saw includes a worm assembly having a lower housing and a worm disposed therein, the worm operably connected to the rotatable shaft of the input device and having a spiral thread, a worm gear assembly having an upper housing and a worm gear disposed therein, the worm gear having a disk comprising a cutout and a plurality of outer teeth engaged with the spiral thread of the worm, and a pair of blades coupled to opposing sides of the worm gear. The rotatable shaft of the input device drives the worm of the worm assembly. Rotational motion of the worm transfers to the worm gear to permit the pair of blades coupled thereon to move linearly in a reciprocating sequence.

A surgical hair clipper assembly includes a clipper body and a blade assembly connected to the clipper body. The blade assembly includes a moveable blade configured to reciprocate to remove hair from a skin area and a blade housing that houses the moveable blade. The blade housing has a guide surface that faces the skin area during a hair removal process. A suction attachment includes a clipper attachment connected to the clipper body and a nozzle structure connected to the clipper attachment and extending distally to an end. The end is located no more than about ten millimeters proximal of a plane defined by the guide surface.

The invention relates to a swing bridge for converting a rotary motion into an oscillating motion, especially into a linear oscillating motion, especially within an electrically driven device. The swing bridge comprises an oscillating body defining a plane. The oscillating body comprises a slot arranged in the plane, wherein a first axis extends through the slot perpendicular to the plane, and a drive shaft protruding perpendicular to the plane along a second axis.

A flex clipper provides a feature to help the cutting blade set float more effortlessly by adjusting automatically to the contours of a client's head to prevent getting stuck and causing cuts and irritation to the scalp. The hair clippers preferably also uses a self-contained motor-driven adjustment mechanism to adjust the relative position of the stationary and reciprocating blades of a common type of blade set. Two momentary switches operable by the thumb of the hand holding the clipper afford a barber total automatic adjustment with the clipper itself in an on or off condition.
