Description

Watch machine with rotating base

Field of technology

The invention relates to a watch machine with a rotating base.

Prior art

The construction of a conventional watch consists of several groups mounted on a fixed base and fixed bridges or in a fixed base and fixed bridges, possibly between a fixed base and fixed bridges. These groups include the penetrator and the run group, and the run group includes the main gear, the stepper, and the oscillator. Furthermore, a group of hands is stored in the watch, which contains the hand gear and the hand control mechanism. Another group stored in the watch is a winding group, which comprises a spring winding gear and a winding mechanism, which is placed according to the structure on the base and / or bridges. All the above groups together form a watch machine, which is inserted into the case by a fixed base.

U.S. Pat. No. 6,520,674 discloses a watch design which deals with an oscillator using magnetism. The flywheel or oscillator has a ring made of a group of magnets, which then induces a voltage in the electromagnetic coils in its vicinity, which are arranged around the oscillator so as to control its amplitude or assist it. The result of this design solution is either less energy-intensive operation, or greater accuracy of the watch. However, it is a watch machine with a classic construction of a solid base.

From US 2014/0286141 a construction of a watch is known, where all components and devices are enclosed in a capsule with a fixed base.

US 2018/2084697 discloses a watch dealing with the display of time by means of disks and its sliding-flipping mechanisms. This solution is also implemented on a solid basis.

Furthermore, a watch solution is known with a system generally called a "tourbilon", which rotates a stepper and an oscillator. It is a patent of Abraham Louis Breguet in 1795.

A common disadvantage of current watch designs is that all auxiliary systems are on the same base as the machine, which is very disadvantageous due to the design. This means that when modifying the machine, all systems must be modified because they are on one base. It is not possible to easily modulate the machine.

The essence of the invention

The existing disadvantages of the known watch machines are eliminated by a watch machine with a rotating base according to the invention comprising a fixed base and a fixed bridge and further comprising a mechanism for controlling the hands and tensioning the spring. The essence of the invention lies in the fact that a rotating base is mounted on the rotating shaft between the fixed base and the fixed bridge, the rotating shaft passing over the fixed base and the fixed bridge. The rotary base carries at least one main gear, at least one oscillator, at least one stepping device and at least one rotary bridge, the rotary shaft passing through a fixed base and a fixed bridge. A spring is mounted on the rotating shaft, which is firmly connected to a fixed base.

According to a preferred embodiment of the invention, a handwheel and a hand control mechanism are mounted on the outside of the fixed bridge, and a spring puller and a winding mechanism are mounted on the outside of the fixed base.

In general, the advantages of the invention can be summarized as follows:

- system variability;

- not all systems depend on the same basis as existing solutions;

- the uniqueness of the solution, because the solution, in addition to the movement of the hands, allows to observe in a shorter or longer period of time the movement of the machine itself, the rotating base and the drive mechanism mounted on this rotating base.

Examples of embodiments of the invention

The basic arrangement of the watch machine shown in Figs. 1, 1b and 3 consists of a fixed base 1 and a fixed bridge 2, which are firmly mechanically connected to each other. A rotary base 3 is mounted on the rotary shaft 5 between the fixed base 1 and the fixed bridge 2. The rotary shaft 5 is mounted in bearings (not shown) mounted in the bore 1.2 of the fixed base 1 and in the bore 22 of the fixed bridge 2. The rotary base 3 is rigidly mechanically connected to the rotary base 3. bridges 4 (comprising a bridge of the main gear 4a, a bridge of the stepping device 4b and a bridge of the oscillator 4c), between which one group of operation rotates, i. main gear 6, stepper 6b and oscillator 6a. The rotating base 3 rotates around the rotating shaft 5.

Said arrangement of the fixed base 1, the fixed bridge 2 and the rotating base 3 forms the basic structural arrangement of the elements of the watch machine in the shape of a letter "U", the other elements necessary to cross the watch being connected to the rotating base. And they are also described in other examples.

Figures 2 and 2a show another variant of the arrangement of the elements of the watch machine, where the rotary base 3 is surrounded by a fixed base 1 and a fixed bridge 2, the fixed base 1 and the fixed bridge 2 around the rotating base 3 forming a closed U-shaped unit. . Arrangement of the rotating base 3 on the shaft 5 and connection of the rotating bridges 4 (comprising the bridge of the main gear 4a, the bridge of the stepping device 4b and the bridge of the oscillator 4c), between which one running group rotates, i. the main gear 6, the stepping device 6b and the oscillator 6a are designed in the same way as in the example in Fig. 3, therefore these elements are not shown in Figs. 2 and 2a.

Fig. 4 shows a watch machine with a basic construction as in Fig. 3 in a variant with two running groups comprising a main gear 6, a stepping device 6b and an oscillator 6a. The rotating base 3 rotates around the rotating shaft 5.

Fig. 5 is a front view, Fig. 6 is a rear view, and Fig. 7 is a sectional view taken along line A-A taken in Fig. 5 with one running group. The fixed base 1 is rigidly mechanically connected to a fixed bridge 2 through which a shaft 5 passes, around which a rotating base 3 rotates, to which rotary bridges 4 are rigidly mechanically connected (comprising a main gear bridge 4a, a stepper bridge 4b, an oscillator bridge 4c) , between which one running group rotates. A fixed spring 8 is connected to the fixed base 18. A spring 7 is attached to the shaft 5 by the inner end, which rotates the rotating base 3. By the toothing 8.1 of the fixed spring 8 fits into the toothing 9.1 of the pinion 9 of the first wheel of the main gear 6, energy is transferred. into the running group, at the same time also to the movement of the rotating base 3.

The surface (outer side) 2.1 (Fig. 7) of the fixed bridge 2 is a space intended for accommodating a group of handles, comprising a handwheel 10 and a hand control mechanism 11. The surface (outer side) 1.1 of the fixed base 1 is intended for the group of the tension (the tensioning mechanism 12 and the gears 13 of the spring tension 7).

Fig. 8 shows a cross-section F-F in FIG. The main gear is mounted on the rotary base 3 below the rotary bridge 4 and its axis is located at the engagement distance with the spring penetration 8. The spring 7 is firmly mechanically connected to the shaft 5 by the inner end, the outer end of the spring 7 being connected to the rotary base 3. energy is transferred to the run group.

The function of the watch machine is to release the energy stored in the spring 7, which is part of the spring 8. The spring 7 rotates the rotary base 3, the spring 8 firmly connected to the fixed base 1 engaging the main gear 6 and thus the rotational energy passes from the spring 7 to the main gear. 6, then to the stepping device 6b and to the oscillator 6a. The result is the movement of the rotary base 3 during the run around the shaft 5.
