Title: Analog clock display with discs

description

Purpose of the bond

is the expansion of the design options for clocks with analog displays combined with easier interchangeability of hands and dials.

The state of the art is known as clocks with analog, concentric pointer display always one Drive of the pointer or pointer disks via concentric Have axes. This has the consequence that behind the dial there are always devices for driving the pointer axes in usually a whole clockwork - must be present.

Deficiencies in the previously known designs lie in the limitation of the design Opportunities there

- it is necessary that the pointers always reach to the central axis,

- Transparent dials and pointer disks make the look on the drive and clockwork, but not on a freely selectable background.

Secondly, there are mechanical and structural deficiencies because the design specifications are relatively tight:

- Drives and sockets always have to be complex Hollow axles can be designed.

- So far, there has always been a mechanically firm connection between the clockwork and the dial (be it directly or through a common frame) leading to an arrangement of the dial between pointers and Clockwork leads.

Third is due in the area of manufacture and repair the mechanical and structural limitations; a multitude of difficulties encountered because of the mobility of the hands and dial the construction is obstructed.

The task

consists in the construction of a concentric, analog display that does without mechanical central axes and better interchangeability of pointers and

Dial allows, while at the same time the design options for clocks to be expanded.

Solution:

Conversion of the pointer into circular, transparent or partial wise transparent disks, which in turn can carry designed pointer symbols. The arrangement of these pointer disks is concentric one behind the other, and is used for the respective execution guaranteed by appropriate guides on the edge of the pointer disks. Allow the tours a rotation of the pointer disks around an imaginary central one Central axis. The pointer disks are driven by a constant speed clock drive via a coordinated gear transmission, which in turn is in teeth on the edge of the Dials engages *

Example of execution:

The executed clock is a grandfather clock for the installation on horizontal surfaces such as those found in the home is.

The clock display has two transparent hand disks (approx. 0.2m 0) (5), (6) for minute and hour hands, material Art glass, with attached pointer symbols. Evenly distributed teeth are milled into the edge.

The parallel guides (2) consist of three transparent ones Plates that are perpendicular to the base plate (1) and between them two slots for receiving the pointer discs form. The slots allow the dials to be easy Game.

The roller guides (3), (4) are on the right and left of the parallel guides mounted on the base plate so that they, together with the parallel guides, the pointer disks a give stable vertical position. The one roller guide is also a gear (3), which by appropriate Gear ratios connected with a coupled mains synchronous motor (7) represents the drive of the pointer disks. Behind the two dials is a simple one Plug-in socket (8) attached to a removable or replaceable dial (9).

Achieved benefits:

- Dj e pointers could be designed regardless of the connection to a central axis.

- The background of the clock can now be freely selected: Interchangeable dials can be selected, i.e. the clock without a dial in front of the background operate.

- There is no construction with hollow axles, no plug-in or Key fits between drive and indicator.

- The arrangement of the dial is, now more freely, could can also be made as a transparent dial in front of or between the pointer discs.

-The construction allows the hands and dial to pass through simple lifting or inserting attached or exchanged.

- The packaging volume for larger watches can be disassembled be reduced.

- Denbar is a contribution from the end user the design of a clock (stickable pointer and number symbols) or a choice when purchasing (e.g. dials).

- Since the dials are not in the The construction of hands and clockwork are intertwined their inclusion in the encapsulated area of e.g. Wristwatches not necessary. The construction of such clocks with exchangeable ones is therefore conceivable and feasible Dials depending on the intended purpose or changes in taste.
