Device for automatically pulling up ears

The invention relates to a device for automatically winding watches with automatic transmission , in particular luxury watches, for example in a safe.

In most cases, quartz-controlled watch gears have not yet been able to prevail in well-known luxury watches. These luxury watches still have automatic gears, and are wound by the movement of a human arm. The movement sets an eccentric in the watch in motion, which rotates and causes it to be wound up as it rotates.

Such luxury watches are not worn every day, but are kept in a safe or similar container most of the time. After a short time, the

% The inventor has set himself the objective of developing a device of the above-mentioned type by means of which these disadvantages can be eliminated or by means of which a continuous winding of the watch can be achieved.

:< To solve this problem, the clock is placed on a

I rotates perpendicular to the axis of the rotating shaft.

I rotates in a vertical plane. In this

j| position, while the watch case rotates around the eccentric

rotates. This winds up the watch.

In order to accommodate different watch straps, a strip of material should be arranged on the rotating shaft on which the watch is tensioned. Preferably, there are even several of these strips of material on the rotating shaft, with the individual strips of material then being connected via corresponding spokes or.
Connecting elements are coupled to the rotary shaft,

According to the invention, the rotating shaft itself passes through a bearing on a housing box and penetrates into this housing box. There it is coupled to a drive that preferably works as an electric motor. If necessary, various gear elements are connected in between.

The electric motor drive can have its own power supply using batteries in the housing box. But there are also safes or similar devices that have their own mains connection, so that it appears possible to also connect the device according to the invention to the mains.

In order to extend battery life in particular, it has proven advisable to couple the drive with electronics that activate the drive for just a few revolutions of the rotating shaft after a certain time. The relevant parameters are determined by the respective clock. There are clocks for which 5-6 revolutions are sufficient to keep them running for several hours.

In the embodiment shown, an open design of the device is shown, but a closed design is of course also conceivable, for example in a Plexiglas box. There should be no limits to the inventive idea here.

Further advantages, features and details of the invention emerge from the following description of a preferred embodiment and from the drawing; this shows in

Fig. 1 is a side view of a device according to the invention for winding watches?

Fig. 2 is a plan view of the device according to the invention shown in Figure 1.

A device P according to the invention for automatically winding watches has a housing box 1. In this housing box 1 there is a drive 2, which in the embodiment shown is designed as an electric motor and has connections 3 and 4 to batteries 5 in a battery compartment 6. It is also conceivable that instead of supplying the drive 2 with energy from the batteries, corresponding mains connections are provided.

A drive shaft 7 leads from the drive 2 into an angle gear 8. There, the movement of the drive shaft 7 is translated to a rotary shaft 9, which leads out of the housing box 1. The rotary shaft 9 passes through a bearing 10.

Outside the housing box 1, the Rotating shaft 9 in two spokes 11 and 12, at whose

A flexible material strip 13 is attached to each end.

The material strip 13 is used to hold a watch 14, with the watch case 15 being arranged in a plane perpendicular to the rotating shaft 9. When the rotating shaft 9 rotates, this watch case 15 also rotates in this plane, so that a weight of the automatic transmission in the watch remains in a certain relative position and the rest of the watch case is rotated around the weight. This winds up the watch.

A rotary knob 16 is also located on the housing box 1, with which, for example, a time interval can be set within which the rotary shaft 9 makes a few revolutions. The control is carried out here by an electronic unit 17, which is only shown schematically.

Furthermore, an operating indicator 18 and a toggle switch 19 for switching the device on/off are indicated by way of example.
