CAMPO DA INVENCAOFIELD OF INVENTION

A presente invengao refere-se em geral a dispositivos de cortar cabelo, tal como maquina de cortar cabelo e aparadores de pelo, tendo um conjunto de Iaminas incluindo uma lamina movel alternando com relagao a uma lamina estacionaria e um sistema de acionamento para acionar ο con- junto de laminas, e mais especificamente, a uma ferramenta extratora para a remogao e insergao de um elemento acionador interposto entre ο sistema de acionamento e a lamina movel. ANTECEDENTES DA INVENCAOThe present invention generally relates to hair clippers, such as a hair clipper and hair trimmers, having a set of Blades including a movable blade alternating with a stationary blade and a drive system for driving ο with next to blades, and more specifically, to an extraction tool for the removal and insertion of a drive element interposed between the drive system and the movable blade. BACKGROUND OF THE INVENTION

Dispositivos de corte de cabelo convencionais, tais como maqui- nas de cortar cabelo e aparadores de pelos, incluem tipicamente um mancal de acionamento acionado pelo eixo de acionamento do motor rotativo. O mancal de acionamento converte ο movimento rotativo gerado pelo motor rotativo em movimento linear na forma de lamina movel alternando com rela- gao a lamina estacionaria.Conventional hair clippers, such as hair clippers and trimmers, typically include a drive bearing driven by the rotary motor drive shaft. The drive bearing converts the rotary motion generated by the rotary motor into linear motion in the form of movable blade alternating with respect to the stationary blade.

Especificamente, ο mancal de acionamento e montado de modo deslocado na extremidade do eixo de acionamento. Desta maneira, ο ele- mento de mancal de acionamento e rodado excentricamente quando ο eixo de acionamento roda. Um elemento acionador e posicionado entre, e conec- tado de modo operavel em, ο mancal de acionamento em uma extremidade e engata a lamina movel em uma extremidade oposta.Specifically, the drive bearing is displaced mounted on the end of the drive shaft. In this way, the drive bearing element is rotated eccentrically when the drive shaft rotates. A drive element is positioned between, and operably connected to, the drive bearing at one end and engages the movable blade at the opposite end.

Em operagao, a rotagao excentrica do mancal de acionamento resulta em uma translagao linear, altemada de uma extremidade do elemen- to acionador, e uma translapao linear, aIternada, oposta da extremidade o- posta do elemento acionador e a lamina movel. Em tempo, condi^des opera- cionais, incluindo calor e fricgao, combinam para causar desgaste e deterio- ragao do elemento acionador. Tal desgaste diminui a eficiencia operacional do dispositivo de corte de cabelo e frequentemente aumenta ο ruido opera- cional, e exigiria substituipao do elemento acionador. A substituigao do ele- mento acionador pode ser dificil devido ao espago Iimitado e tolerancias de encaixe.In operation, eccentric rotation of the drive bearing results in a linear, altered translation of one end of the drive element, and a linear, alternate, opposite translation of the opposite end of the drive element and the movable blade. In time, operating conditions, including heat and friction, combine to cause drive element wear and deterioration. Such wear decreases the operating efficiency of the haircutting device and often increases the operating noise, and would require replacement of the drive element. Replacing the drive element can be difficult due to limited space and snap tolerances.
