Description

The invention relates to an electronic rotary pendulum clock

according to the preamble of claim 1.

It is the purpose of the invention to have one with few electronic parts To create table-top rotary pendulum clock with precise quartz time measurement and so a relative Simple mechanical and electronic design to be supplied to the sales community.

Various electronic rotary pendulum clocks are known.

So is the drive of the rotary pendulum with its own electronic The circuit and its bifilar-wound coil are complex and require a lot of work tied together.

Depending on the electronic version, the drive circuits are for Rotary pendulum clocks equipped with astable multivibrators or with amplifier circuits. As already mentioned, all of these circuits have several electronic elements and additionally a higher power consumption.

The above-mentioned disadvantages are eliminated by the invention. As already mentioned in the main claim, a second coil is three-dimensional to the quartz movement coil connected separately in parallel, which receives the same switching pulses as for the Stepper motor of the quartz movement are delivered. These change impulses have an impact repelling the rotary pendulum with its magnet system in every half oscillation, so that the torsional vibration (360 - 4000) is guaranteed.

In the accompanying drawings, the invention is based on an exemplary embodiment and explained accordingly in a description below.

Figure 1 is a rear view of a rotary pendulum clock according to the invention figure 2 the side view of the magnetic system of the Dren pendulum clock. The table-top rotary pendulum clock Fig. 1, which consists of the housing (1) and the pillars (2) and (3) is screwed onto a base (4). The quartz movement (5) is located in the housing (1) with the stepper motor coil (6) and below the quartz movement (5) is a second Drive coil (7) connected in parallel to coil (6).

The rotary pendulum (8) is provided with a magnet system (9), which is shown in detail in FIG.

The magnets (9), (10), (11) and (12) in Fig. 2 are arranged so that a closed magnetic field is created, which via the drive coil (7) in Fig. 1 and Fig. 2 oscillate.

The rotary pendulum (8) is, as usual, at the bottom of the base (4) in a stone bearing screw (13) stored and guided above in the bearing plate (14). The bearing plate (14) is riveted to the printed circuit board (15), which also has the quartz movement (5) attached to the coil (6). The energy for the quartz movement (5) is supplied from the battery (16) in the base (4) via the plus-minus contacts (17) (18) to the two pillars (2) and (3) over the contact angles (19) and (20), which are on the conductor tracks the printed circuit board (15) and thus the power supply to the quartz movement (5) is guaranteed is.
