"Unlocking a shaving head"

The invention relates to an electric dry shaver with a housing with at least one inner shaving element with one with the inner shaving element cooperating provided with hair entry openings outer shaving element which is arranged in a cap removably arranged on the housing, and with a locking device for locking the * cap on the housing, the housing having at least one resiliently movable Contains locking element that also has an outside

of the housing is provided movable part which cooperates with a corresponding recess provided in the cap.

The disadvantage of such a construction is

however, that greater forces have to be overcome when attaching and removing the cap, which is what the user of the apparatus does is perceived as annoying and undesirable from the point of view of wear and tear for the locking mechanism is.

The construction according to the invention, with which it is intended to obviate this disadvantage, is thereby characterized in that the cap with an operating element is provided for the locking element.

A preferred embodiment fox-m is thereby

characterized in that · the operating element for the locking element is designed as a push button, of which a part facing the inside of the cap is arranged State of the cap opposite a rounded end of the movable part of the locking element, the Push button against the action of the spring load of the movable Part can be pressed into a position in which the cooperation between the movable part and the corresponding recess is canceled.

An embodiment of the invention is shown in the drawing and is described in more detail below. It zei _{¥ 8} : _{9849 / o276}

Fig. 1 is a diagrammatic representation of the Dry shaver,

Fig. 2 is a section through the unlocking mechanism when the cap is locked,

3 shows a section through the unlocking mechanism the moment the cap is unlocked.

1 shows the housing 1 with the removable cap 2 arranged thereon. There is a push button 6 on both sides of this cap (only one can be seen). The push button 6 is enclosed in the cap 2 by a plate 3 which is attached to the cap. The push button can only perform a slight axial movement. In the cap 2 a recess' + is provided through which the conically extending rounded end 9 of a pin 8 protrudes. This pin can perform an axial sliding movement in a recess 10 in the housing 1. In the arranged state of the cap, the push button 6 and the pin 8 are in alignment. The pin is pressed into the recess h by a spring 11 and thus clamps the cap in such a way that the outer shaving element 12 can work well together with the inner shaving element, which is not visible. The part 7 of the push button 6 facing the inside of the cap cooperates with the end 9 of the pin 8. When a force is exerted on the push button 6 against the spring pressure of the pin 8, a position is reached in which the end 9 of the pin 8 is pressed out of the recess H of the cap 2, whereby the cap can be removed. When attaching the cap to the housing, it is not necessary to press the push buttons 6. By the

conical end 9 of the pin 8 and the inclined surface 5 on the cap 2, the cap can be easily pressed onto the housing.
