Toothed belt clock with parallel time reading

Clocks of the usual design consist of a movement, a dial and a hand shaft in the middle of the clock, on which the hour hand and the minute hand are mounted centrally. The time is displayed by the rotation of the hands.

The invention specified in claim 1 is based on the problem of creating a clock with which the time can be read from separate, parallel scales arranged in hours and minutes by means of short hands mounted on toothed belts or chains and performing a translational movement. The time is read from left to right, first the hours on the left, then the minutes on the right.

The novelty of this watch consists essentially of

1). the toothed belt insert (optionally chain insert)

2) the separate short hand reading

3) the clutch for optional operating function / control function

The main innovation of this watch is that the power of the barrel wheel is not only delivered to one point (minute wheel), but is also transferred to another hour and minute wheel at the exact opposite point, which are each connected to the toothed belts for hours and minutes via an angle gear, coupling and bearing.

Structure of the dial:

The dial is basically divided. On the left-hand side there are the hour digits 0,2,4,6,8,10,12 in ascending order and in between there are marking lines (instead of 1,3,5,7,9,11). To the right of this is the toothed belt (13) (or chain) with the short hand (15) attached to it, which touches the dial. (In the middle is the metal case (1), optionally just the metal case of the watch manufacturer, optionally a viewing glass to observe the movement). On the right-hand side there are the minute digits 0,10,20,30,40,50,60 in ascending order and in between there are marking lines representing 5,15,25,35,45,55. To the left of this is the toothed belt (14) with the short hand (16) attached to it, which touches the dial.

The operation of this clock differs from all previously known clocks, because the short hand (15) and the short hand (16) do not move in a rotating manner (as previously known), but in the form of a translational movement through the toothed belt (13) and the toothed belt (14) (optionally chains).

The toothed belt (13) is engaged with the lower toothed belt wheel (26) and the upper toothed belt wheel (33). The toothed belt (14) is engaged with the lower toothed belt wheel (37) and the upper toothed belt wheel (38). There are therefore two separate toothed belts for hours and minutes and both move the respective hands like an endless conveyor belt.

The innovative display mechanism works separately for hours and minutes.

The hours are read by means of a short hand (15) which is attached to the toothed belt (13) and moves from bottom to top along the dial scale 0 to 12 and points to the left.

The minutes are read by means of a short hand (16) which is attached to the toothed belt (14) and also moves from bottom to top along the dial scale 0 to 60 and points to the right.

This creates the impression of a parallel time reading.

For this system to work, it is necessary to fix 3 short hands at exactly the same distance from each other on the toothed belt (13). One of the short hands (15) is located on the upper, visible side of the toothed belt (13), while the other two are located on the lower, invisible side of the toothed belt (13).

While the first short hand has passed the number "12" and disappears from the dial, at the same time the second short hand appears below at the number "0".

The third short hand is invisibly positioned below the dial.

The toothed belt (14) on the right-hand side of the dial works in exactly the same way (minute function). Therefore, the description is unnecessary.

Solution:

The problem (page 1) is solved with the features listed in claim 1.

Characteristics:

1). Hour and minute hands are mounted on moving toothed belts or chains

assembled.
2). The hour hand is on the left side of the dial, the minute hand is on

positioned on the right side of the dial.
3). Both hands move from bottom to top in an ascending manner, giving the impression of parallel time readings.

Benefit achieved:

It enables an analogue time reading on a clock without rotating hands, because the hands of this clock move in a straight line.

(Translation movement).

The time reading for hours and minutes is done on 2 separate scales.

An example of implementation is explained below:

The view for all subsequent technical descriptions is the top view, i.e. the view into the upper side of the work.

If possible, an elongated movement (2) should be used as the drive base. Theoretically, the starting point for this new watch is an existing movement (2), which must be modified accordingly in order to properly perform its new function.

This molded movement (state of the art) is basically made up of the following components: metal case (1), molded movement (2), winding crown (3), crown wheel (4), ratchet wheel (5), barrel wheel (6), factory-fitted minute wheel (7), third wheel (9), seconds wheel (10), escape wheel (11) and balance wheel (12). To clarify once again: the state of the art therefore includes the above-mentioned components, which are provided with the following reference symbols on the drawing: 1,2,3,4,5,6,7,9,10,11,12. All other components, which are provided with the reference symbols 18 to 41 on the drawings, are part of my innovation and will be integrated into the existing technology after appropriate modification.

In contrast to a standard mechanical movement, in this version the driving force of the barrel wheel (6) is transmitted via a minute change drive (39) to an additional minute wheel (17), which is positioned exactly opposite to the factory minute wheel (7) located above, therefore the mainspring must be designed to be correspondingly strong.

For example :

The gear located to the bottom right of the barrel wheel (6) is the additional minute wheel (17), which is in mesh with the bevel wheel (40); the gear located to the bottom left of the barrel wheel (6) is the hour wheel (18), which is in mesh with the bevel wheel (34).

Let's first look at the drive unit / adjusting unit for hours. It consists of the shaft (21) with the middle coupling half (20) firmly mounted on it, and the left coupling half (22), two pillow block bearing units (24 + 25), the lower toothed belt pulley (26), the upper toothed belt pulley (33), the toothed belt (13), the adjusting wheel (27) and a locking mechanism (28,29,30,31) for the two functions of operation or adjusting function. The two toothed couplings consist of 4 coupling halves: the right coupling half (19) and the middle coupling half (20) on the one hand, and the left coupling half (22) and the inner toothing of the adjusting wheel (23) on the other. The lower toothed belt pulley (26) mounted on a bearing, through which the shaft (21) passes, acts as a drive gear for the toothed belt (13) and drives the upper toothed belt pulley (33). The shaft (21) engages with its external teeth in the internal teeth of the lower toothed belt wheel (26). The lower toothed belt wheel (26) also has external teeth on its front side to accommodate the toothed belt (13). The drive force of the clockwork is transferred via the shaft (21) to the toothed belt wheel (26). The toothed belt (13) with three short hands (15) attached to it is tensioned via the lower toothed belt wheel (26) and the upper toothed belt wheel (33). The lower toothed belt wheel (26) is located at the number "0", while the upper toothed belt wheel (33) is located at the number "12". There are two positions for the couplings of the drive unit / adjusting unit: The first position is the operating position. The second position is the adjusting position. In the operating position, the right clutch (19 + 20) is in power engagement, while the left clutch (22 + 23) is open.

In this arrangement, the power of the clockwork is easily transmitted from the hour wheel (18) via the angle wheel (34) and the right clutch (19 + 20) and the shaft (21) connected to it to the toothed belt wheels (26 + 33) and the toothed belt (13). The toothed belt (13) in turn moves the short hands (15) forward so that the clock is in operation. The winding crown (3) on the right side of the clockwork is only used to wind the mainspring, not to correct the time.

The time setting is done as follows:

In order to set the time of the short hand (15), the right-hand coupling half (19) is released from its engagement with the middle coupling half (20) by pulling out the adjusting wheel (27) and the left-hand coupling half (22) is brought into engagement with the inner toothing of the adjusting wheel (23).

In addition, the shaft (21) is shifted to the left by a certain length.

Furthermore, a locking mechanism (28,29,30,31), which is triggered when the adjusting wheel (27) is pulled, ensures that only exactly 2 positions can be assumed, either the operating position or the setting position.

Marcus Simic * " ** "* "45^5 Essen, Rieseishof 14

Page : 6 Example:

The locking mechanism consists of the following elements:

A slotted screw (28) with an attached compression spring (29) and an adjusting lever (30) with two recesses for the two functions operation / time setting. The adjusting lever (30) is attached with an adjusting lever pin (35) and connected at the top to a compression spring (29). A locking ring (31) is mounted on the right-hand side of the adjusting wheel (27), which is in the right-hand recess when in the operating position. When the adjusting wheel (27) is pulled, this locking ring (31) moves to the left and pushes the protruding nose upwards. Shortly afterwards, the locking ring (31) is pressed into the left-hand recess by the spring tension and is now in the setting position. To ensure that this system functions smoothly, the distance between the center of the left recess and the center of the right recess is exactly as long as the two distances resulting from separating the right coupling half (19 from 20) and engaging it with the left coupling half (22 with 23). In the operating position, the locking mechanism therefore ensures that the right coupling half (19) is exactly in its toothing with the middle coupling half (20). This is achieved by a small shaft driver (32) which is pushed to the right by the adjusting wheel (27), thus pushing the shaft (21) and the middle coupling half (20) attached to it to the right onto the toothed, right coupling half (19), which is firmly connected to the bevel gear (34). The coupling half (19) on the right is now connected to the bevel gear (34). The angle gear (34) is again mounted on its right side (pillow bearing 36), while on the opposite side it is firmly connected to the right coupling half (19) in order to accommodate the middle coupling half (20).

In the setting position (by pulling on the adjusting wheel (27)), the locking mechanism (28,29,30,31) causes the toothed coupling halves in idle mode (left coupling half (22) and inner toothing of the adjusting wheel (23)) to be connected to one another and the middle coupling half (20) is separated from the opposite toothed coupling half (19) and comes into idle mode by moving the shaft (21) to the left. The shaft (21), which transmits the force, is mounted in three places (pillow bearings 24,25,26) and must still be movable for the purpose of adjusting the time. So that the force of the adjusting lever (30) acts evenly on the adjusting wheel (27), it is advisable to install a locking mechanism (28,29,30,31) on the right and left side of the adjusting wheel (27) at exactly the same distance. (Viewed from the left side of the housing (1) (side view). Since the curved locking ring (31) has a round shape, the recesses of the locking levers (30) should be adapted to the shape of the locking ring (31) in order to function properly.

For the minute function, everything works exactly like this, only on the opposite side of the movement and at 12 times the speed. It is exactly the same locking mechanism, which only has to be turned over before installation. Therefore, a detailed description is unnecessary.

The mainspring of the watch must be dimensioned accordingly large, since the design requires 9 additional gear friction points and 12 additional bearing friction points, which have a correspondingly high energy requirement for a desired operating time of 24 hours to 48 hours.
