Description

Technical field

The invention relates to the watch industry and can be used for the manufacture of watches, in particular for fastening a capsule with a clock mechanism in the watch case.

State of the art

Closest to the claimed latch is a capsule latch with a clockwork inside the watch case, containing a locking element in the form of a metal ring having a thin-walled shell covering the side surface of the capsule and elastic tabs attached to the shell that protrude in different directions, protruding into the gap between the capsule and the case and in contact with the shoulders on the inner surface of the watch case. In the middle part of the thin-walled shell, there are slots in which protrusions extend on the outer side surface of the capsule, which allows fixing the shell on the capsule (see French Patent No. 1509590 MKI G04B 31/00 of 03/07/1969). In known watches, the capsule is suspended inside the watch case on elastic legs. Such capsule attachment is not reliable enough when exposed to external loads. In addition, the presence of paws, bent in opposite directions, significantly complicates the manufacture of watches. In a watch with a decorative case made of precious metals, the legs of a metal frame scratch the surface of the watch case.

Thus, there is a need to develop a watch with an improved capsule fastening system in the watch case.

Utility Model Disclosure

The objective of this utility model is to develop an improved capsule retainer with a clock mechanism inside the watch case, eliminating the accidental loss of the capsule from the watch case and having a less damaging effect on the wall of the watch case and capsule. Another objective of the utility model is the development of a latch having higher technological characteristics in order to reduce the cost of manufacturing the latch and the watch as a whole.

To solve these problems, a capsule retainer with a clock mechanism in the watch case is proposed, comprising a fixing element covering the side surface of the capsule and elastic tabs attached to the fixing element that protrude outward relative to the fixing element, while in the proposed fixative, the fixing element is made in the form of a frame and equipped a pressing end on one of the end edges of the frame, for contact with the corresponding supporting platform on the side surface of the capsule body, while the elastic tabs are connected Nena frame on the side of the biasing end and extending outwardly relative to the frame in a direction opposite edge frame at an angle to the surface of the urging end face.

Preferably, the latch is made of a polymeric material.

Preferably, in the proposed retainer, the elastic tabs are inclined to the pressing end at an angle of 45-75 °.

In addition, in the proposed latch frame is made in the form of a polygonal frame, in particular in the form of a quadrangular frame, and, preferably, in the form of a rectangular frame.

In addition, in the proposed retainer, the pressing end is made at least on two opposite walls of the rectangular frame.

In addition, in the proposed retainer, the walls of the rectangular frame have an equal height.

In addition, in the proposed latch clamping ends protrude relative to adjacent two other walls of the rectangular frame.

In addition, in the proposed latch clamping end is equipped with protruding outward shelves, and the elastic tabs are connected to the shelves.

In addition, in the proposed retainer, the frame walls adjacent to the walls with a pressing end are equipped with elastic elements in the form of an arch, allowing the two halves of the rectangular frame to move relative to each other, while the arches are located above the zones for the passage of the transfer shaft.

Preferably, the latch is made of a polymeric material.

Preferably, in the proposed retainer, the elastic tabs are inclined to the pressing end at an angle of 45-75 °.

In addition, in the proposed latch frame is made in the form of a polygonal, in particular, in the form of a quadrangular frame, and, preferably, in the form of a rectangular frame.

In addition, in the proposed retainer, the pressing end is made at least on two opposite walls of the rectangular frame.

In addition, in the proposed retainer, the walls of the rectangular frame have an equal height, or the pressing ends protrude relative to the adjacent two other walls of the rectangular frame.

The frame of the capsule retainer with the clockwork inside the case is installed between the watch case and the capsule wall so that the retainer frame fits tightly on the capsule body, rests on the support platform of the capsule body with its pressing end and contacts the free ends of the elastic tabs with the support platform on the inner wall of the watch case (on bead or groove), pressing the capsule to the rim of the watch case and fixing it in this position. Since the paws are made elastic, when the frame is installed, they are easily deformed, and have a minimal effect on the wall of the watch case, providing reliable fixation of the capsule with the clockwork in the watch case.

The implementation of the capsule retainer made of polymer material reduces the damaging effect of the frame on the wall surface of the watch case and capsule.

The inclination of the elastic tabs at an angle of 45-75 ° to the pressing end provides the optimum force to press the capsule to the rim of the watch case and reliably prevents the capsule from shifting in the longitudinal and transverse directions in the watch case.

The implementation of the latch in the form of a continuous polygonal frame, in particular in the form of a quadrangular frame, and, especially, in the form of a rectangular frame simplifies the manufacturing technology of the latch and provides tight contact of the pressing end of the latch with the second supporting surface. The presence of individual elastic legs, which can be easily distributed along the pressing end of the frame, provides an optimal distribution of the effort to compress the capsule to the watch case, taking into account the peculiarities of the watch design and the shape of the watch case.

Placing the pressing end on at least two opposite walls of the rectangular frame provides the most optimal conditions for fixing the capsule with the clockwork in the watch case of complex shape along two opposite edges while keeping the capsule case from displacement. Moreover, by varying the offset of the pressing ends relative to adjacent walls of the frame, it is possible to reliably fix in the watch case not even a flat capsule with a clockwork.

The presence of outwardly protruding shelves with which the elastic legs are connected provides the ability to use the latch in the watch with increased gaps between the wall of the watch case and the side wall of the capsule.

Equipping the walls adjacent to the walls with the pressing end, arch-shaped elastic elements that allow the two halves of the rectangular frame to move relative to each other, makes it possible to reliably fix a capsule with a non-cylindrical side surface in the watch case, while elastic arches can be used to pass the transfer shaft.

The proposed utility model provides fixation of the capsule with the clockwork inside the watch case with a different external shape of the capsule and watch case, even with the cover removed, preventing the capsule with the watch mechanism from falling out, with minimal damaging effect of the frame on the watch case and capsule.

EXAMPLES OF IMPLEMENTATION OF A USEFUL MODEL

It should be understood that this description is only to illustrate the implementation of the utility model, and in no way limits the scope of protection of the present utility model.

In the figures, the same position indices correspond to the same watch elements.

In FIG. 1 shows the hours in which the proposed capsule retainer was used. The watch contains a case 1 with an inner shaped surface 2 and a rim 3, framing the opening of the case. In the case there is a capsule 4 with a clockwork mechanism resting on the bezel 3. The glass 5 is located in the opening of the case above the dial of the capsule. The case 6 of the capsule is sealed and has an external side surface 7. The watch has a closing case 1 cover 8. The watch is equipped with a lock 9 for fixing the capsule 4 with a clock mechanism inside the case for 1 hour. Here, under the capsule is meant any design of the clockwork, which is a separate functional monoblock, which has its own case, inside which the clockwork itself is located, and which is equipped with elements (cover, panel, etc.) that cover the internal cavity of the capsule body.

The latch 9 is made in the form of a rectangular frame 10, shown in figure 2. The rectangular frame 10 covers the side surface 7 of the wall of the body 6 of the capsule 4 with its walls 11 and 12 and has elastic tabs 13 that protrude into the gap between the capsule 4 and the case 1 hour.

The housing 1 has a support element, for example, in the form of a shoulder 14, on the inner surface of the housing 1, made with the first support pad 15, and the outer edges of the elastic tabs 13 reach this first support pad 15 and are in contact with it.

The watch is equipped with a second supporting platform 16 located on the side surface 7 of the capsule body 6, and the rectangular frame 10 of the capsule retainer is equipped with pressing ends 17 on the edge of the wall 11 of the rectangular frame 10, resting on the second supporting platform 16, while the elastic tabs 12 are connected to the rectangular frame 10 on the side of the pressing end 17 and extend outward relative to the rectangular frame in the direction of the opposite edge of the rectangular frame at an angle of 45-75 ° to the surface of the pressing end 17 to the first support plate schadki 15 on the inner wall of the watch case.

The bead 14 acts on the outer edges of the elastic tabs 13, and, using the elastic tabs 13, presses the capsule 4 against the bezel 3 of the watch case. The outer edges of the elastic tabs 13 are inside the shaped surface 2 and the shoulder 14 prevents the movement of the outer edges of the elastic tabs 13 outside the housing 1. As a result, the capsule 4 with the clock mechanism is securely fixed inside the housing for 1 hour, even when the cover 8 is removed.

The elastic tabs 13 are distributed along the pressing end 17 of the rectangular frame 10. The locations of the elastic tabs are consistent with the design of the housing 1. In the simplest embodiment, each pressing end has one elastic tab 13. The height of the elastic tabs 13 is determined by the relative position and dimensions of the 1-hour case and the case 6 capsules.

The pressing end 16 may be equipped with shelves protruding outward 18. The size of the shelf is mainly determined by the gap between the case 1 hours and the wall 7 of the capsule 4. Figure 2 shows a narrow shelf 18, but it should be understood that the shelf does not have to be narrow. In this case, the elastic tabs 13 are connected to the shelves 18.

The latch 9 can be made in the form of a rectangular frame 11, as shown in figures 2 and 3, but it should be understood that the latch 9 can be made in the form of any polygon: a quadrangle, a trapezoid, a rhombus, a hexagon, an octagon, etc. In particular, as shown in figure 4, the latch can be made in the form of a quadrangular frame having slightly convex side walls 12, and fillets at the junction of the side walls 11 and 12.

The walls 12 of the frame 10 are equipped with arches 19, enabling the two halves of the frame 10 to move relative to each other in the longitudinal and transverse directions. Arches 19 can have any shape: arched, rectangular, triangular, step, etc. Typically, arches 19 are located in areas for the passage of the translational shaft or other shafts to control and regulate the clockwork.

Depending on the shape of the watch case and capsule case, different supporting platforms can be used. In particular, the flange surface on the inner wall of the watch case or the groove surface made on the inner surface of the watch case can be used as the first supporting pad, and the flange surface on the side surface of the capsule case, or the groove surface on the side surface of the wall of the capsule body.

In the above-described embodiments, the retainer 9 of the capsule 4 in the 1-hour case, in particular, the rectangular frame 10 is made of a polymeric material, for example, high-pressure polyethylene, linear polyethylene, nylon, organosilicon polymeric materials, and the like.

When assembling the clock, the capsule 4 with the clock mechanism is installed in the watch case 1 so that it rests on the bezel 3. Then, a rectangular frame 10 is put on the capsule 4 and moved along the capsule in the direction of the second supporting platform 16 until it stops. In this case, the elastic tabs 13 come into contact with the hole in the center of the shoulder 14 and are bent by the wall of the hole in the direction of the axis of the housing for 1 hour. Using a technological tool, such as a ring, press on the elastic tabs 13, deforming them along the axis of the watch case. The elastic tabs 13 bend and pass through the hole in the center of the bead 14, and then straighten, abutting against the first support pad 15. The bead 14 acts on the outer edges of the elastic tabs 13, and using the elastic tabs 12, presses the capsule 4 to the bezel 3 of the watch case. In this case, the outer edges of the elastic tabs 13 are inside the contoured surface 2, and the shoulder 14 prevents the outer edges of the elastic tabs 13 from moving outside the case 1. As a result, the capsule 4 with the clock mechanism is securely fixed inside the case for 1 hour, even with the cover 8 removed.

To dismantle the capsule with the clockwork from the watch case, it is necessary to bend the elastic tabs 13 in the opposite direction and remove them from under the bead 14 of the watch case, for example, bending each of the elastic tabs 13 in turn.

When using a latch in the form of a rectangular frame 10, the walls of which are equipped with elastic arches 25, when the frame is mounted on the capsule body, the frame halves are moved apart relative to each other so that the frame covers the capsule body, the frame is moved along the capsule in the direction of the groove on the wall of the capsule body, and the frame 21 into the groove on the capsule body. When the frame 10 enters the specified groove, the halves of the frame converge, and the frame 10 is fixed in the groove. Further, fixing the capsule in the watch case does not differ from the technology described above.
