Description

The invention relates to a cover to be attached by a bayonet lock to close the compartment for the power source of an electric watch.

With such a Beekel it is proposed according to the invention, that he has an engaging means to their rotational movement circular disc consists of one on one of its Front faces arranged wreath-shaped thin part, that is attached at least at certain points on its inner edge and on its outer circumference a name of ura him has lugs evenly distributed around it, which protrude beyond the side surface of the disc and form means to close the lid on the part whose opening it is closed should, through. To attach bayonet lock

An embodiment of the invention is shown in the drawing. and is described below · It shows J

Fig. 1 is a partial section through the axis of the power source of an electric clock and

Fig. 2 sees a lower part of the lid, which the opening in the bottom of the clock, through which the battery is inserted and removed.

The movement of the illustrated electric clock contains a a dial 2 supporting board 1 “It is in one - 2-sealed Housing with a middle part bottom 3 and one through a glass hoop 5 held in its correct position glass 4-housed »

The part 3a of the middle part bottom which forms the actual bottom 3 has a circular opening 6, which the soldering and removing a * to power the movement serving electric battery 7 enables »

The opening 6 is closed by a cover, which also consists of a circular disk S, in which two diametrically intersecting grooves 9 are formed, which an actuating part _$, for example a coin, which enables the disk 8 to be rotated for attaching and removing the cover , should serve as an intervention _β

The opening 6 is provided with recesses, the entrances for "Descriptive hook-in or attachment approaches to be described in more detail below." of the disk 8 ο

The disc 8 has an annular recess 10 in which a ring-shaped thin part 11 is arranged, the inner circumference of which has several incisions 12, with which projections 8a of the disc 8 engage so that the disc and the rim 11 with one another are non-rotatable _o The in
