Non-linear clock with cam gear and spur gear pre-stage

Human clock - clock with non-linear time display

Description

The motivation and background of the invention is the aim of depicting the daily routine, which people experience as not being uniform, in its ups and downs, its dynamics, in the clock display: "Human" clock.

In contrast to known clocks, which generally use centrally uniformly driven display elements (hands), the tips of which point to digits or numeral substitutes arranged on circular or circular orbits or orbits derived from circles (e.g. ellipses), the inventive idea of the clock described here is that a display element (2, 2a) moves on a meandering path (1a) and thereby enables a non-linear time display even though the drive is derived from a conventional clock motor (5) with a constant angular velocity. The clock motor can be designed as a quartz movement, synchronous movement, radio clock movement or mechanical weight or spring-driven movement with a pendulum or balance wheel.

From a technical point of view, this is a cam disk gear consisting of:

the stationary cam disc (1), designed as a dial; the roller (2), with an attached element (2a); the cranked articulated lever (3) - also referred to as a swing arm -, if required provided with a weight compensation (3a);

the spring ( 4 ) ensuring the roller is in contact with the cam disc; the ring disc uniformly driven by the motor ( 5 ) via pinion ( 6a ) with

Gearing ( 6 );
Support plate ( 7 ) for motor ( 5 ) and cam disc ( 1 );

Spacers ( 8, 8a ) between carrier plate ( 7 ) and cam disc ( 1 ) and

Dial centre plate (1b);
the swivel joint ( 9 );

and the guides (10) for the toothed ring disk (6) - preferably designed as rollers.

The inventive idea is based on enabling an eccentric arrangement of the motor shaft and the center of the ring disk (6) that drives the articulated lever by interposing a timing stage with the ratio i=12 between the motor and the non-linear gear. This means that access to a fixed plane - here the carrier plate (7) - is retained behind the dial (1) even in the middle area, in order to cover the mechanics with a dial center plate (1b), for example, so that only the dial and the milled track with the display element are visible from the outside. This opens up completely new design options for the appearance.

The application of this principle is independent of the size of the "clock", so it can be used for wristwatches, pocket clocks, table clocks and large clocks.

An embodiment of the invention is described with reference to Figures 1 to 3 .

Fig. 1 shows the front view of the non-linear clock, while in Fig. 2 the dial - the cam disc (1) - has been removed to show the

to show the mechanism behind it. Fig. 3 shows the layered structure of the clock in a side view.

The motor (5), preferably a mechanical spring-driven mechanism with a pendulum (11), is mounted on the carrier plate (7). The dial - i.e. the stationary cam disc (1) - with the meandering cam track (1a-) is also rigidly connected to the carrier plate using several spacer bolts (8). The inner part of the dial (1b) is attached to the carrier plate (7) using bolts (12) so that it is flush with the dial (1).

In the space between the carrier plate (7) and the cam disk (1), the pinion (6a) is placed on the minute shaft (5b) of the motor (5), which is in engagement with the teeth of the ring disk (6). On the ring disk (6) there is a hinge pin (9) onto which the hinge lever (3) is placed.

The roller (2), preferably provided with a molded element (2a) attached to the dial side of the articulated lever (3), is rotatably mounted in such a way that it is pressed against the cam track (1a) by the pulling effect of the spring (4), which is attached with one eye to the other end of the articulated lever (3) and with the other eye to the disk (6). The roller is preferably designed with a central groove into which the sheet thickness of the cam disk (1) and the inner part (1b) fits, so that the roller (2) is guided in the axial direction by the cam disks and there is no need for any further security against loss of the roller.

When the motor ( 5 ) rotates, the ring disk ( 6 ) rotates guided in the guide rollers ( 10 ) with the articulated lever and the roller ( 2 ), whereby the roller ( 2 )

rolls along the meandering curved path (1a) and maintains contact with the curved path (1a) through the tension of the spring (4), thus following the vibrations of the path.

This results in different roller speeds along the track, with higher speeds on curved sections whose distance from the center is greater, and lower speeds on curved sections whose distance from the center is smaller, with corresponding accelerations or decelerations.

If the gap in the guideway between ( 1a ) and ( 1b ) is designed to be so small that the roller can move in the track with slight functional play (internally and externally guided cam roller), the spring ( 4 ) can be dispensed with.
