Description

Technical field

The invention relates to the field of watch industry, in particular to the mechanical elements of a pocket or wrist watch and its case.

State of the art

Known are watches containing a decorative case having an inner shaped surface located in a decorative case, an airtight capsule formed by a case ring with a glass fixed to it and a lid coupled to the case ring, a clock mechanism fixed in the case ring and means for fastening the sealed capsule in the decorative case (EP 0762240 A1, 03/12/1997).

A disadvantage of the known solution is its manufacturing complexity, due to the need to organize space to accommodate connections with the lid, which leads to an increase in the cost of the product. Moreover, the presence of one common cover for the capsule and the decorative case excludes the repair of the decorative case without violating the tightness of the capsule with a clockwork.

The closest analogue to the claimed object is a watch containing a decorative case having an inner shaped surface, an airtight capsule located in the decorative case, formed by a case ring with a glass fixed to it and a lid connected to the case ring, a clockwork mechanism fixed to the case ring, and a sealed fastener capsules in a decorative case (RU 2298820 C2, NIKA LLC, 05/10/2007). At the same time, said fastening means is made in the form of a cover of a decorative body having a shaped fastener installed with interference in conjunction with the internal shaped surface of the decorative body, while the body ring is made with external shoulders having a deformable support on the shaped fastener.

A disadvantage of the known solution is that the claimed solution does not provide water resistance to the clockwork. In addition, the drawback is the complexity of the watch assembly due to the presence of additional fastening elements and the cover of the decorative case.

The implementation of the invention

The invention is a watch with an internal case placed in a waterproof case that provides water resistance to the watch mechanism, since a protective case, which, in addition to serving as a means of attaching the internal case to the external one, performs the function of sealing the watch mechanism located in the internal case. In this case, the thickness and weight of the watch are reduced, since the lower part of the inner case from the side of the clockwork is formed by a protective casing of an elastic waterproof material.

As is clear from the drawings, the main component of the claimed invention is a protective casing 10, which is made of an elastic waterproof material. In particular, polymeric materials such as rubber, polyethylene, silicone, plastic and polyurethanes (synthetic elastomers) can be used. In this case, the protective casing of plastic can be made by injection molding, machining or grown on a 3D printer.

In carrying out the invention, a number of assembly technologies must be followed. For example, to make a watch according to the embodiment shown in FIG. 1, a sheet of elastic waterproof material is put on the outside of the clock mechanism on the inner case. As a waterproof material can be used polyethylene, sheet rubber, etc. Next, the inner case with the formed casing is installed in the outer watch case. In this case, excess material can be cut off after installation. Thus, this waterproof elastic material forms a casing 10. At the same time, during installation, the elastic casing will compress the inner case, providing water resistance to the clockwork. In addition, it should be understood that the protective casing can also be made as a finished part, made in the form of a glass or box, made of polymer material, rubber or plastic by injection molding or grown on a 3D printer. That is, the casing 10 is formed from a waterproof elastic material either directly during the assembly process by crimping the inner case, subject to the temperature conditions, and insulating the clockwork, or the casing 10 can be manufactured separately and simply assembled on the inner case during assembly, also insulating the inside installed inside watch case. Moreover, the specified inner case does not contain a back cover, since its role is played by a protective casing. Thus, the weight and thickness of the protective case is reduced, and the water resistance of the watch is generally increased (according to the invention, the claimed watch provides a sufficiently high degree of protection against moisture of 30-50 m).

For clarity of understanding of the invention, it is considered appropriate to provide the following explanations. It is known that protection from moisture is usually divided by degree. This degree is referred to as WR, that is, Water Resistant - “waterproof”. The water resistance indicator can be 30 m, 50 m, 100 m, 200 m, 300 m. But do not assume that in a watch marked 30 m you can dive to a depth of 30 meters, this mark only means that the watch can withstand a pressure of 3 atmosphere. In practical application, all of the above markings can be distinguished in this way:

30 m (3 atm) - such a watch will tolerate a small accidental ingress of water. You can wash your hands in them or allow yourself to be exposed to light rain. It is impossible to immerse them completely in water. It is also worth avoiding the effects of a directed water stream. After all, even in an ordinary tap, the water pressure can significantly exceed 3 atmospheres. So, such procedures can cause depressurization of the clockwork.

50 m (5 atm) - such a watch will allow you to swim in the pool or take a shower without worrying about your wrist companion. It is worth considering that at the time of a hand hitting the water or when jumping into the water, with a sharp stroke, the pressure can for some time exceed the permissible 5 atm - and, unfortunately, you will have to hand over your favorite watch for repair. Therefore, if you are not alien to water sports, give preference to watches that have a higher degree of protection against moisture.

100 m (10 atm) - such a watch is designed to float in them. And even jumped into the water and plunged into the water for a couple of meters. But serious in-depth research is not for them yet.

200 m (20 atm) and higher - these watches are designed specifically for diving, they can withstand deep water pressure. Watches with this mark undergo particularly severe tests.

Thus, a watch manufactured using the claimed technology can provide good water resistance to the watch mechanism, sufficient for a user who leads a regular measured lifestyle, since they will not allow him to worry about a watch getting wet in the rain or having accidentally taken a shower.

At the same time, the design of the claimed watches implies that the inner case can be installed both from above on the side of the dial, and from the bottom (in this case, the watch case will have a bottom cover).

For example, as shown in FIG. 5 hours can be accomplished by putting on the outside of the inner case of a protective casing, partially covering the side surface of the inner case and closing the lower part of the mechanism. In this case, the protective casing is made of an elastic waterproof material, for example, such as a polymer material, rubber or plastic, by injection molding, obtained by machining or grown on a 3D printer. The side walls of the protective casing are made in such a way that when put on the inner case, they are tightly pressed into it, providing water protection.

In FIG. 8 and 12 show additional mounting options for the inner case with the protective cover 10 to the outer case. Moreover, according to FIG. 8, the inner case is attached to the outer one by means of means 15, for example, mounting tabs or the like. In FIG. 12, with the help of additional mounting elements 22, made as part of the protective casing, these can be elements made in the form of spring-loaded “petals”, which, when installed in the external casing, abut against the lower edge of the “petals” in it, thereby securing the inner casing external. In this case, the protective casing is pulled onto the fastening means by means of a tight fit. That is, the landing of the protective casing occurs due to the elastic tension of the protective casing on the inner case, which ensures the water resistance of the clock mechanism inside the inner case.

Moreover, the watch according to the invention can either have a crown or not have one. So, according to figures 9, 10, 11, the watch has a conversion head with a conversion shaft, and the crown when installed in a clockwork passes through a protective casing. The protective casing is made of an elastic material, such as rubber, and thus provides water resistance and protection of the mechanism, squeezing the transfer shaft, preventing water or dust from penetrating through the holes. That is, the micro-hole of the crown is tightly closed due to the properties of the protective casing, which provides a tight compression of the crown / translation shaft and the insulation of the inner case.

Alternatively, a plug (Fig. 10) or a side elastic insert can be made in the protective casing. The insert provides water protection by tight installation in a protective casing. It is also made of elastic material.

In addition, figure 13 can be considered as an attachment option for the inner case. According to this embodiment, the watch can be made by putting on the outside of the inner case a protective casing partially covering the side surface of the inner case and closing the lower part of the mechanism made of an elastic waterproof material, for example, such as polymer material, rubber or plastic. To ensure the fixation and water protection of the protective case, the watch has an additional mounting ring, which compresses the side walls of the protective case on the inner watch case, tightly fixing it and providing dust and water protection to the watch mechanism. That is, the mounting ring 23 is an additional element that allows you to tightly compress the protective casing around the inner case.

In this case, it should be noted that the inner case contains glass, a time indicator and a clock mechanism. It is known that different means of indicating time can be used in watches. Under the time display means understand the totality of indicator elements that allow the user to determine the current time. The time indication means may be in the form of an arrow indication, a scale indication, a disk indication, a digital indication, and the like.

The invention can be used both in portable watches and in stationary watches.

The invention can use almost any quartz or mechanical standard-produced clockwork with an arrow indicating the current time in its standard function of uniform rotation of the axes and the countdown, having output shafts, an hour axis and a minute axis, on which the hour and minute hands are normally mounted.

The clock mechanism can be basic, commercially available both as a standard version and with additional refinement, for example, the frictional external end of the winding spring, in order to provide a “endless winding” of the spring and prevent its breakage or overvoltage.

From the foregoing, it follows that the invention ensures the achievement of the required technical result, which consists in improving the manufacturability of the assembly and manufacture of watches, a significant reduction in the thickness and weight of the watch case, as well as providing water protection for 3-5 atm watches.

The analysis also shows that all the general and particular features of the invention are essential, since each of them is necessary, and all together they are not only sufficient to achieve the purpose of the invention, but also make it possible to realize the invention in an industrial way.
