Description

Battery-powered movement with an electrically powered pendulum

The innovation relates to a battery-powered movement, especially a quartz movement, with a from the clockwork electrically driven pendulum of the type mentioned in the preamble of claim 1.

Battery-powered clockworks have today because of the lower manufacturing costs and the higher accuracy as well as the easy handling largely mechanical clockworks, especially pendulum clockworks, repressed. Nevertheless, for certain purposes, e.g. for style clocks, cuckoo clocks and the like. Conventional Clock constructions pendulum necessary. In order to satisfy this need, too, they are battery-powered Clocks are offered with a pendulum, which is electrically driven by the clockwork and only for decorative purposes is provided.

it A clock with a decorative rotating pendulum works

If, for example, from DE-GM 1 720 498.

The clockwork constructions that had become known up to now were not universally applicable because the clockworks with an electrically driven pendulum were not easily usable for clocks without a decorative pendulum. For this reason, different ones had to be used depending on the application Movements are manufactured and kept in stock.

As a result, the demand arose for the manufacturer to create a battery-powered movement that would work for both Applications is suitable.

This requirement is met after a first proposal, as explained in DE-GM 78 09 694. In this construction, a pendulum device is placed on a clockwork case from the outside, whereby the self-aligning bearing on the top of the housing and the drive electronics with a drive coil, to which a permanent magnet attached to the pendulum arm is assigned, are located on the underside of the housing. The pendulum arm is curved in an approximately U-shape outside the clockwork housing in front of its front guided around the pointer shafts.

This arrangement has certain disadvantages for the user.

Since the pendulum is arranged outside the clockwork case, the overall arrangement takes up considerably more space
to claim as a battery clockwork without a pendulum. So
can be a known way by a pendulum
A supplemented battery clock mechanism cannot easily accommodate smaller clockwork casings, in particular flat clockwork casings, at least not without redesigning them.

Also, compared to conventional pendulum clocks, the bearing of the pendulum in front of the front of the movement is perceived as annoying at least when that
Clockwork as closely as possible to traditional forms
ajar style clock is to be installed.

After all, the design effort is off
the mentioned utility model known pendulum bearing and arrangement relatively large.

The innovation was based on the task of creating a battery clockwork of the type mentioned in the preamble, which does not have these disadvantages.

This task is achieved primarily by the fact that the pendulum differs from the previously known construction is arranged within the work carrier below the pointer shafts in such a way that the oscillating pendulum arm outside of the work structure, preferably in front of the battery.

In this construction, which can be realized with simple means, a pendulum with a straight pendulum arm are used, which in its appearance and in terms of its oscillation behavior does not depend on pendulums differs in conventional watch movements.

As with the solution according to DE-GM 78 096 94, the drive electronics in the solution according to the innovation for the pendulum located in the front area of the clockwork within one that can be connected to the clockwork case Additional housing can be accommodated. After another suggestion is according to the innovation of this additional housing electrically and mechanically with the movement housing with the help of Contact pins and contact sleeves can be connected, as is characterized in detail in claim 5.

In the same additional housing, in addition to the drive electronics, a game or percussion mechanism with an electronic Melody or percussion memory are housed, which in a known manner via a a melody or a loudspeaker housed in the same housing provided with sound outlet openings Stroke sequence in given, ζ.

For wall clocks, it is advisable to use the controls and to direct the sound outlet openings of the additional housing downwards.

It is of particular advantage for the manufacturer or supplier if, as is also proposed, the coil body for the coil for driving the pendulum is attached to the same circuit board as the components the melody or percussion memory carries. Furthermore, the contact receptacles can be soldered to the same printed circuit board or, if necessary, the loudspeaker and the operating elements, e.g. a switch, must be attached.

Other structural details are the subject of the subclaims and explained in detail below with reference to the preferred exemplary embodiment. So is in the Drawings shown as follows:

The drive electronics fed from the battery 14 energizes the control coil 29 at each or every second zero crossing of the pendulum in such a way, - that the pendulum in Direction of oscillation receives a shock through which the oscillation is maintained.

At the lower end of the pendulum arm 30, a pendulum lens 31 adjustable along the pendulum arm is attached.
