Description ​

The disadvantage of all analogue clocks used in living spaces to date is that the time cannot be read in dim light or in total darkness. Even phosphorescent hands or numbers on conventional clocks are only partially and inadequately usable in poor lighting conditions.

The aim of the invention is to use modern technology to achieve a high-quality timepiece that is easy to read, so that the time can be read even in poor lighting conditions.

This goal is achieved by replacing the conventional pointers, which are usually made of plastic or metal, with a laser beam.

This passes through the Plexiglas dial filled with a colored liquid and is therefore visible in daylight and even in total darkness.

The clock (see drawings) makes use of the principle that a laser beam is only visible in certain ambient materials.

For example, the red beam (A) of a laser tube (B) is deflected vertically out of the Plexiglas base by deflecting mirror (C) and reflected horizontally by deflecting mirror (D) into the center of the dial (E).

As the laser beam (J) travels through the air, it can become visible through dust or smoke in the air.

The deflection mirror (F), which is driven by a clockwork (I) at the speed of the hour hand, deflects the beam again by 90 degrees so that it (the laser beam A) passes through the colored liquid (K) in the dial (E) and thus becomes visible.

Clock - 2 - pointer has, is through of thus only via a relative exact Read off Dial ( E) a Although the the size

the time (+/- 1 min.) also and especially possible in twilight and darkness.

To avoid unwanted reflections, the back and the outer edge of the dial (E) are matte black on the inside.

The division of the dial (E) is done by lines on the edge of it: h-sectors and h/6-sectors are marked differently.

The power supply for the laser tube (B) is provided by a separate power supply unit.

Ventilation holes on the sides of the base (H) allow air circulation and thus dissipation of the heat generated by the laser tube (B) located in the base (H).

Furthermore, a clock according to the invention should be visually pleasing through the combination of visible, modern technology and simple geometric form in the form of a functional everyday object and, as an exclusive element, should complement and round off an existing interior design and/or set new contrasts or focal points.
