Description

Technical field

The invention relates to devices for measuring time, in particular to a wrist watch with a mechanism placed inside a capsule that can be removed from a decorative case, and can be used in the watch industry in the manufacture of watches and their elements.

State of the art

Wristwatches are known, where the clockwork with the dial and the viewing window are parts of a single capsule, which can be manually removed from the decorative case.

So from the document US 11449008 B2 known watch, consisting of a capsule of the described type and a hollow case with tabs for attaching the strap. On the front side of the capsule there is a viewing window with a dial, and on the inside, facing the user's wrist, there is a bezel. For fixing in the housing, grooves are made on the side surface of the capsule. When assembling the watch, the capsule is installed inside the hollow case and fixed by turning the bezel, on the surface of which there are marks corresponding to the closed and open positions of the capsule locking mechanism.

The disadvantage of this embodiment is the location of the bezel on the inner surface of the case. Prolonged contact of the wrist with the embossed surface of the element can cause inconvenience when wearing the watch for a long time. In addition, rubbing against the surface of the user's wrist may cause the capsule locking mechanism to accidentally open.

From the document RU 2625907 C1, a watch is known, consisting of a removable capsule with a clockwork, a hollow case and removable tabs for attaching a strap. The fixation of the capsule inside the housing is carried out due to the adhesion of the protrusion on the inner surface of the housing with the groove on the side surface of the capsule. The capsule ejection mechanism is formed by a spring mounted on the inner surface of the housing cover. The clutch is released when the capsule is pressed vertically: a compressed spring pushes it out of its socket.

The disadvantages of this technical solution include the ease of operation of the mechanism for opening the lock holding the capsule inside the decorative case. Accidental pressure may lead to the removal of the capsule, which, in turn, may lead to the loss of the watch mechanism.

The closest analogue of the claimed technical solution is the wristwatch described in the document RU 2298820 C2. The analogue capsule is located inside a decorative case with a lid installed with an interference fit and fixed with a shaped bartack. The capsule consists of a body ring with glass fixed in it and a capsule cover, also installed with an interference fit. A sealing ring is placed between the mating surfaces of the body ring and the capsule cover, which ensures the tightness of the capsule. For precise positioning of the clockwork inside the capsule and the capsule inside the decorative case, deformable elements are included in the design of the watch, one of which provides support for the clockwork on the capsule cover, and the second - the support of the capsule on the shaped setting.

The disadvantages of the analogue include the need to perform a large number of shaped surfaces, in particular, the inner surface of the case ring and the outer surface of the capsule cover, the inner surface of the decorative case, shaped setting, which greatly complicates the watch manufacturing process. In addition, each procedure for dismantling and assembling the decorative body requires the replacement of one of the deformable elements - an insert that provides support for the capsule on the shaped clip, which complicates the repair procedure and increases its cost, since each time this part must be purchased or manufactured.

The proposed technical solution is devoid of these disadvantages. The fixation of the lid in the capsule body is carried out not by mating the shaped surfaces, but by placing two elongated protrusions on the outer surface of the lid in the corresponding recesses on the inner surface of the capsule body. The installation of the case cover is carried out with an interference fit using a plug, which has a simpler shape than the shaped bartack of the analog, which simplifies the process of assembling the watch. The absence of capsule parts with shaped surfaces that are difficult to manufacture simplifies the process of their (details) manufacturing. The design of the invention also does not include parts that must be replaced every time the capsule or decorative case is dismantled.

The claimed watch also has the following advantages.

The positioning of the clock mechanism inside the capsule is also carried out using a non-metallic setting ring, however, the shape of this element differs significantly from the shape of the ring used in the analogue design. The height of the setting ring of the declared watch coincides with the height of the mechanism, and the shape of the outer edge of the ring exactly repeats the shape of the inner surface of the capsule case, which allows you to more effectively dampen the resulting vibrations and more accurately position the watch mechanism.

The positioning of the capsule inside the decorative case is carried out using two symmetrical clamps with inclined stops, which allows you to more accurately position the capsule and securely fix its position.

The use of screw connections for fixing the relative position of the body and the capsule cover, as well as the capsule and elements of the decorative body increases the reliability of the design.

The proposed watch is also characterized by the presence of elements that were absent in the design of the analogue, namely, the presence of an additional window with a second dial, made in the center of the cover of the decorative case.

Thus, the aim of the present invention is to provide a clock with two viewing windows, the mechanism of which is located inside a removable capsule, consisting of two elements that do not have shaped surfaces that are difficult to manufacture. At the same time, to increase the reliability of the design, the body and the cover of the capsule, as well as the capsule assembly and the decorative body are connected by screw connections. And the positioning of the clock mechanism inside the capsule and the capsule inside the decorative case is carried out with the help of deformable non-metallic elements resting on the side walls of the parts relative to which the positioning is carried out, due to which the positioned assembly units are securely fixed and the vibrations arising during operation are effectively damped.

The technical result of the claimed invention is to increase the positioning accuracy and reliability of fixing the mechanism relative to the capsule and the capsule relative to the decorative body, while increasing the efficiency of absorbing vibrations transmitted to the capsule and the mechanism.

In FIG. 3 shows the clock in section: a - section along the vertical plane A-A, 6 - section along the horizontal plane B-B.

In FIG. 4 shows a general view of the clock in section B-B along the planes of the connecting screws.

The presented drawings are given to explain the essence of the claimed invention and do not limit other options for its implementation. In particular, the shape of the decorative case, capsule, their covers, dials and viewing windows may be different, and the front dial may not have chronograph dials and additional hands of the pointer mechanism.

Implementation of the invention

The mechanism of most watch models on the market is located directly inside the decorative case, closed by a lid. This design does not allow you to quickly remove the mechanism for repair or replacement / restoration of the decorative case.

The mechanism of the proposed watch is placed inside a sealed capsule installed inside the decorative case, which can be easily removed for further operations, both with the watch mechanism itself and with the elements of the decorative case, which greatly simplifies the repair and maintenance of the watch.

The claimed watch is characterized by the presence of two dials, the first of which is located in a standard way, and the second is located on the inside of the watch facing the user's wrist. This dial can be both decorative and functional. In the second case, the clock becomes two-sided, and the user has the opportunity to find out the time, regardless of which side (front or end) the decorative case faces it. Both dials are also inside the capsule. The presented drawings show only a decorative dial. It is obvious to a specialist that the version of the functional dial will not structurally differ from the main dial considered in detail, and a complicated clockwork with an additional pointer mechanism, kinematically connected with the first pointer clockwork used for display the current time on the main dial 3.

The sealed capsule consists of a hollow cylindrical metal body and a flat metal cover. A transparent viewing window is fixed on the upper edge of the cylindrical body. The second transparent viewing window is fixed in a hole made in the center of the flat cap of the capsule. In the preferred embodiment, the viewing windows are made of sapphire glass.

The positioning of the clock mechanism inside the capsule case is carried out using an elastic non-metallic adjusting ring, the height of which coincides with the height of the mechanism. Placing the clockwork inside the elastic element allows you to effectively dampen the mechanical vibrations that occur during the operation of the watch. In the upper part of the adjusting ring, outer shoulders are made, the shape of which repeats the shape of the inner surface of the capsule body. Thus, the displacement of the adjusting ring and the clockwork placed in its center in the horizontal plane is limited.

The main dial is flat and is mounted on top of the front surface of the setting ring. The shape of the main dial also follows the shape of the inner surface of the capsule body. In a preferred embodiment, the front dial also has three additional chronograph dials - hours, minutes and seconds. It should be understood that the variability of the implementation of the main dial 3 may be different and will depend on the used watch mechanism of a simple or complicated type. In particular, on the 3 o'clock dial it is possible to display, in addition to the standard indications of minutes, seconds and hours, also an indication of the moon phases, calendar, etc.

The second dial is placed on the capsule cover above the second viewing window. The second viewing window and end dial may have a different shape than the main dial. In particular, they may be in the form of a circle. In this case, if the second dial is functional, that is, configured to display the time, its design may be identical to the main dial 3 or different from it. In this case, the specified functional implementation of the lower end dial will be identical to conventional dials. In turn, the clock mechanism will have a complication in the form of the presence of a second, additional pointer mechanism, which will be connected to the first pointer mechanism directly by means of a gear train, or through a gearbox, if the second dial is configured to display the current time, for example, in a different time zone than the time zone displayed on the main dial 3, or displaying the phases of the moon, or displaying the calendar, etc. The design of such a clock mechanism is obvious to a person skilled in the art and does not require disclosure in this application. For example, the design of a complicated watch mechanism can be made by analogy with the known ones (see, for example, RU 2356078, JP 2014044071, SV. Tarasov "Watchmaking Technology", 2nd edition, supplemented and revised, Mashgiz, Moscow, 1963. , US 2209642 A).

For connection with the body, a vertical cylindrical protrusion is made on the inner surface of the capsule cover, the shape of which repeats the shape of the inner surface of the cylindrical body of the capsule. At least two elongated teeth are made on the outer side of said protrusion. When assembling the capsule, a vertical protrusion is installed with an interference fit inside the capsule body, and the teeth are fixed in grooves on the inner wall of the body.

The capsule case has a protrusion along the perimeter of the inner wall, so that after installing the cover, the clock mechanism is sandwiched between two dials.

As you can see, the design of the capsule is quite simple and allows, if necessary, to remove the clock mechanism from it without significant effort.

The capsule assembly is installed inside a decorative case, closed by a lid.

The positioning of the capsule inside the decorative body is carried out with the help of two elastic non-metallic elements, which are symmetrical and form a ring around the capsule. Each element is characterized by the presence of at least two inclined stops, which provide support on the inner wall of the decorative body. Thus, the movement of the capsule in the horizontal direction inside the housing is limited.

The metal cover of the decorative body along the perimeter has a vertical bend, with a gap placed inside the decorative body during assembly. The gap is sealed with a thin metal plug.

In a preferred embodiment, the decorative body is made from precious metals such as gold, silver or platinum.

Additional fixation of the elements relative to each other is carried out by making two screw connections, the first of which connects the capsule cover with its (capsule) cylindrical body, and the second connects the cover of the decorative body with the cover and the capsule body. The drawing shows the foot attachment to the body.

A hole is made in the decorative case and the capsule case for installing the winding shaft, and a slot is made in the wall of the setting ring for the same purpose. In the event that the watch is equipped with a chronograph, these elements may contain additional holes for installing the shafts of the chronograph pushers.

As follows from the description of possible implementations of the claimed invention, the proposed capsule watch with two viewing windows achieves the claimed technical result, namely, an increase in the positioning accuracy and reliability of fixing the mechanism relative to the capsule and the capsule relative to the decorative case, while increasing the efficiency of absorbing vibrations transmitted to the capsule and the mechanism. vibration absorption is carried out through the use of non-metallic elastic elements for positioning the capsule and clockwork. And the shape of these elements, the inner wall of the capsule body and screw connections allow you to accurately position the capsule and the clockwork and fix them in the desired position.

Considering the novelty of the set of essential features, the technical solution of the problem, the inventive step and the materiality of all general and particular features of the invention, proven in the "Prior Art" and "Disclosure of the Invention" sections, proven in the "Implementation and Industrial Implementation of the Invention" section, technical feasibility and industrial applicability inventions, the solution of the set inventive problems and the confident achievement of the required technical result in the implementation and use of the invention, in our opinion, the claimed invention satisfies all the requirements for patentability for inventions.
