DESCRIPTION:
BRIEF SUMMARY
This invention relates to an electric shaving apparatus having at least one short-hair cutter assembly arranged on a housing and at least one control switch slidably mounted on the housing for vertically adjusting a long-hair trimmer in the direction of the short-hair cutter assembly from an "Off" position to at least one operating position.
An electric shaver with a short-hair cutter assembly arranged on a housing and a at least one control switch slidably mounted on the housing is already known (DE-A-28 43 947), the control switch serving to adjust the long-hair trimmer vertically in the direction of the short-hair cutter assembly from an "Off" position into an operating position corresponding to a position of use. The movement of the long-hair trimmer is locked relative to the shaver housing in any position, so that during shaving the long-hair trimmer is only movable into another position of use, for example, a "trimming" position, by actuation of the control switch, in which position the movement of the long-hair trimmer is again locked, being thus unable to change its position while in use.
From DE-A-2 343 116 an electric shaving apparatus is known having a short-hair cutter assembly arranged on the housing and a long-hair trimmer slidable in vertical direction and adapted to be held immovable both in the "Off" position and in a position of use provided above the contour of the short-hair cutter by means of a retaining spring locking into recesses provided on the slide means of the long-hair trimmer, such as to ensure operation of the long-hair trimmer in the predetermined position of use. Taking into account the indicated extreme position of the long-hair trimmer relative to the short-hair cutter assembly, this known shaving apparatus precludes a simultaneous operation of short-hair cutter assembly and long-hair trimmer for cutting short and long hair.
It is an object of the present invention to provide an electric shaving apparatus of the type initially referred to with two cutter assemblies, such as to enable both cutter assemblies to be put to optimum use simultaneously in at least one operating position.
According to the present invention, this object is accomplished in that the long-hair trimmer is spring-mounted in vertical direction in at least one operating position. This ensures in a simple manner that the long-hair trimmer engages the skin surface at a consistently optimum angle, catching and shaving the long hair which the short-hair cutter assembly has not caught or is unable to catch. For example, when the position of the shaver relative to the skin surface is changed while shaving, causing also the skin engaging surface of the short- and long-hair cutter assemblies to be changed, the long-hair trimmer will automatically adapt to the new situation, thereby ensuring that both cutter assemblies continue to engage the skin surface optimally. This improves the shaving performance significantly, while at the same time reducing the aggressive action of the long-hair trimmer assembly, so that the risk of skin irritation or injury can be diminished. As a result, the long-hair trimmer does not get caught on creases on the skin or facial contours as, for example, the jaw bone. The sliding action of the long-hair trimmer over the skin surface becomes more pleasant, presenting an improvement.
In a further feature of the device of the present invention, an additional possibility is afforded in that a spring is provided between the control switch and the long-hair trimmer, maintaining the long-hair trimmer in a position of use yielding to the pressure of the spring.
In a still further feature of the present invention, the long-hair trimmer is advantageously disposed on a slide means provided in the housing and adjustable by means of the control switch.
Finally, in a preferred embodiment of the solution of the present invention, a plate receiving the long-hair trimmer is adjustably mounted on the slide means in one or several guiding members, the slide means being adjustable to various positions by me
