DE1548134C3 - Clock with date and day of the week - Google Patents

Description

The object of the invention is a clock with date and weekday information, in which the respective Indications of the date of the day of the week immediately next to each other in the same dial window are visible.

In the known clocks of this type, the date indicator consists of one around the clockwork axis rotatably mounted ring and the weekday indicator from a rotatable about the same axis Disc. The first letters of the day of the week are arranged radially on this disk. In order to These letters can be capitalized as possible, is used in some of the well-known clocks the day of the week even indicated outside of the date ring. In this case the wings of the date and day of the week are no longer on the same level, because the information on the The spokes of the day of the week indicator on the hub of the hour wheel extend beyond the date ring have to. The date ring is internally toothed to drive the two indicators and the weekday indicator bears a star. The ones with this internal gearing and the Star cooperating drive fingers and locking levers are arranged between them, so that the dial side the work plate is almost completely covered by the calendar mechanism.

Because the date and day of the week are displayed next to each other in the same dial window should be visible, there must be no gap between the two calendar indicators. on the usual one in the known clocks with two separate calendar windows in a circular zone Space between the weekday disc and the date ring provided dial support must therefore can be omitted in the clocks of the type mentioned, so that the dial only can be supported on the edge of the clockwork. The arrangement of such a calendar mechanism on a clockwork also entails a considerable increase in the overall height.

The object on which the invention is based is to create a watch of the type mentioned at the beginning Category in which the entire calendar mechanism is less bulky. Space within the date ring leaves free for a support of the dial and is simpler in structure than the previous one well-known watches.

The clock according to the invention is characterized in that the display of the date and the day of the week consist of concentric, adjoining, internally toothed rings, which by means of fingers are switchable, soft on the same in the between the teeth of the two rings Circular zone mounted drive member sit.

An embodiment of the clock according to the invention is shown in the drawing.

Fig. 1 is a plan view of the dial side of the movement with the dial removed, and Fi α. 2 a partial section along line H-II of Fig. I.

The movement of the clock shown is one with a center second and indirectly driven minute and hour hand. The work plate 1 of this clock thus carries a tube 2 in the middle, which serves as a bearing for the shaft 3 of the center second serves and around which the minute tube 4 with the one with rich friction The minute wheel 5 and the hour wheel 6 are rotatably mounted on it.

The calendar mechanism of the illustrated watch includes a date and day of the week rings. 7th and 8, which have internal teeth 9 and 10, respectively. During the weekday ring by one with a drive wheel 11 firmly connected finger 12 is operated, acts as a spring-loaded, on the Wheel 11 pivotably arranged pawl formed finger 13 with the toothing 9 of the date ring together to advance it. The drive wheel rotatably mounted around a fixed pin 14 of the work plate 11 itself is driven by the hour wheel 6 via a transmission gear with wheel 15 and drive 16 driven so that the wheel 11 makes one revolution in 24 hours. The teeth 9 and 10 sit on cropped parts of the rings 7 and 8 to support the same in the axial direction guarantee. The day of the week ring 8 becomes one on the work plate 1 through the outer edge 17 Washer 18 secured by screws 29 axially. The date ring 7 is similar by the Outer edge of bridges, not shown, under the weekday ring, held axially. The fixed one Disc 18 has a recess 19 in which a cooperating with the toothing 10 of the weekday ring 8, spring-loaded locking lever 20 is housed. The locking lever 20 is around a fixed pin 21 of the disk 18 is pivotably mounted and is axially held in place by a pivot plate 22. With

together. tion 9.

For the arrangement of the Kalenderme- The rings 7 and 8 are relative to each other einchanismus the work plate 1 is sunk in such a way that it can be adjusted 5 times by turning the clock hands around Mitsie at the edge around the date ring 7 can be turned briefly forwards and backwards one night at night. Has support surface 23 for the dial 24. Except for every back and forth movement of the pointer, switches the surface 23 serves the surface of the disk 18 of the fingers 12 the ring 8 once forwards and then also as a support for the dial 24, so backwards again, while the finger 13 the ring 7 that the latter does not even then firmly switch rings 7 and 8 only forward. When moving back the jams when its curvature of the shape of the work pointer jumps the finger 13 over the next tooth plate 1 does not match exactly. of the ring 7.

When the rings 7 and 8 are in the rest position, the clock described has the advantage that the

is one of your information 26 or 27 in the window 28 in both rings of your calendar mechanism through the

of the dial 24 visible. The respectively visible 15 the same organ 11 are driven. With this watch

Items 26, 27 appear immediately next to each other.This simplifies the fact that the same toothing

preferably lying outside this toothing in a plane above the finger 13

is located, the advancement of the ring 8 accomplish drive fingers and with the tooth within this

can, its path of engagement must cooperate at least approximately 20 lying locking lever. For the

shirt must be the same as that of finger 13. There are also two support options for the dial.

For this purpose, the day of the week is required 27 on the periphery, one on the edge and one in the middle,

catch the ring 8 twice in a row removed, the latter being used at the same time to a

gen so that the distance between two adjacent organ of the calendar mechanism can be accommodated.
