Definitions

  • the present invention relates to a wristwatch which has a clockwork, a housing in which the clockwork is located, a support part arranged on the housing for fastening a bracelet, and a base.
  • Wristwatches always have a watch case, which is usually composed of a watch glass, a watch case and a base.
  • a watch case which is usually composed of a watch glass, a watch case and a base.
  • the manufacturing costs of the watch case have a significant influence on the overall costs of the watch. It has therefore already been proposed that often with the help of relatively expensive forging or
  • the object of the present invention is therefore to improve the structure of previously known clocks in such a way that the constructional, manufacturing and assembly-related outlay for producing the clock can be reduced.
  • a clock which is constructed in accordance with this concept, can be machined with cost-effective CNC processing machines, such as for example turning and milling. Another advantage is that conventional and inexpensive rod material can be used as the starting material.
  • the construction of the clock according to the invention allows a quick assembly by numerically controlled
  • these advantages mean that the technical outlay for producing a watch according to the invention can be reduced to such an extent that a watch with a metallic shell can be offered in a price segment by usually only placing plastic watches.
  • the watch shell has at least one shoulder on its inner lateral surface, the shoulder surface of which can be essentially annular and can be oriented vertically to the lateral surface.
  • the clockwork carrier and the watch glass each resting on one of these paragraphs.
  • the heels can be arranged one above the other, the opening width of the heels decreasing from the watch glass to the floor. This means that the watch can only be assembled from the watch glass side, except for the insertion of the base.
  • Figure 1 is a top perspective view of the support member of a watch according to the invention.
  • FIG. 2 shows a sectional side view of a watch according to the invention along a longitudinal axis of the housing
  • FIG. 3 shows a detail of the representation from FIG. 2;
  • FIG. 4 shows a plan view of a clockwork carrier of a further clock according to the invention
  • FIG. 5 shows a plan view of a supporting part of a watch
  • Fig. 6 is a sectional view of a watch having the components shown in Figs. 4 and 5.
  • a supporting part 1 can be seen, which is one of the main components of the structure of the watch according to the invention.
  • the supporting part 1 has an annular section 2 and two receptacles for fastening a bracelet to the housing.
  • the two receptacles are designed as flanges 3 and 4 arranged in pairs.
  • the support part 1 is a solid component, the height of which is usually at least 1.5 mm. It has been manufactured by turning. Of course, it could also be created with the help of punching.
  • this support part arranged on the housing of the watch can have a metallic material, for example steel, hard metal or gold. In this case, the shape could also be generated differently than by the aforementioned methods.
  • the visible surface can be produced by finishing treatments such as polishing.
  • the glass 8 and the seal 9 are arranged on the so-called watch shell 5, in which the clockwork support 7 is integrated. As can be seen in the representation of FIGS. 2 and 3, the glass 8 is fixed to the watch shell 5 solely by radial pressure of the seal 9.
  • the glass 8 is a plane-convex disc with an outer edge 18, which can be cylindrical or slightly conical. If necessary, the glass can be made from mineral glass.
  • the shell 5 is mounted on the supporting part 1 through the cylindrical inner surface 10 of the annular section 2 of the supporting part 1 by inserting the clockwork support 7 with its outer and likewise cylindrical mounting surface 11 into the annular section 2.
  • the tolerances of the supporting part and of the clockwork support are coordinated such that the two surfaces 10, 11 cannot make any relative movements due to static friction or a press fit.
  • the housing is closed on the side opposite the glass (underside) by a base 12 which has an annular outer wall 13.
  • the wall 13 is provided with a ring through which there is an undercut 14 trains.
  • the ring of the wall 14 engages in the lower inner part of the annular clockwork support 7, which is also provided with a corresponding undercut. As a result of this engagement, a watertight seal 29 is pressed into a recess, which is delimited by corresponding rectangular notches on the bottom 12 and the clockwork support 7.
  • the wall 13 of the base 12 engages in such a way that it exerts a radial pressure against the wall of the clockwork support 7, as a result of which the base 12 is held on the support 7.
  • the radial pressure brings about or at least contributes to that the shell 5 is fixed to the supporting part 1.
  • the central part of the floor 12 can be of any structure or material. It can in particular be formed in one piece with the wall 13. According to a preferred embodiment shown in Figure 2, the central part of the bottom is a thin glass plate 15, e.g. on
  • Mineral glass which is arranged in a groove with a rectangular cross section.
  • a projection formed on the outside of the base by the groove encompasses the glass with approximately 0.1 mm. This connection allows the two elements 12 and 15 to be sealed off from one another.
  • all elements of the watch shell and of the back are exactly circular components which are produced by numerically controlled machining machines, in particular turning and / or milling machines, and by numerically controlled grinding machines, as a result of which large quantities can be achieved per unit of time.
  • the clockwork carrier 7 is pressed into the supporting part 1 in such a way that the former with one or more radial ones Openings 28 (FIG. 2) are arranged opposite openings 26 and 27 (FIG. 1) of the supporting part 1.
  • actuators can also be installed in the openings after the clockwork has been installed.
  • Fig. 3 shows how the clockwork is to be fixed in the housing and how the housing is to be closed.
  • the illustration illustrates the implementation of the assembly.
  • This figure shows the glass 8 and the circular clockwork support 7 of the shell 5, the supporting part 1, the base 12 and the spacer 19, which is arranged between a dial 20 and the clock glass 8.
  • the inner lateral surface of the clockwork support 7 shows three shoulders 22, 23, 24 arranged one above the other.
  • the clockwork 21 is supported with a circumferential edge on the first paragraph 22, which is the smallest distance from the floor 12 of the three paragraphs.
  • the paragraph 23 following in the direction of the watch glass 8 is located directly opposite the dial 20.
  • the circuit board of the clockwork 21 and the dial 20 are exposed - but without play - on one another and are arranged in an inner opening of the clockwork 7 between the paragraphs 22 and 23 .
  • the spacer 19 which is designed as a solid ring, for example as a steel ring, and its height is dimensioned such that it is pressed onto the shoulder with a friction fit.
  • the spacer 19 has a tapered profile in the direction of its outer edge.
  • the height of the spacer 19 corresponds to the distance between the two paragraphs 23 and 24, the glass 8 resting on the latter with its flat side.
  • the distance (in the vertical direction) of the shoulders 22, 23, 24 and the height of the spacer 19, the dial and the edge of the plate 21 are coordinated with one another such that the spacer 19, the dial 20 and the board 21 are clamped against each other in the vertical direction.
  • the height of the spacer is somewhat larger than the distance between the two shoulders 23 and 24.
  • the glass is held by radial pressure of the seal 9 alone.
  • the profile of the seal 9 is essentially rectangular on the outside, while it has an essentially oval cross section on the inside.
  • the seal 9 is inserted into a circumferential groove 25 which is essentially rectangular in cross section and which is screwed into an upper part of the clockwork support 7.
  • peripheral outer surface 18 and the inner wall 30 of the upper part of the clockwork carrier - in terms of their diameter - a play of e.g. 0.1 mm.
  • the seal cannot be recognized from the outside.
  • the glass can be easily dismantled. This can be done, for example, by blowing compressed air into the watch through the opening of the crown or through the bottom opening of the housing, which presses the glass out of its seat on the seal (9).
  • Handling devices can be executed very quickly.
  • the components of the watch are inserted into one another from the glass-side opening of the housing from top to bottom (in the illustration in FIGS. 2 and 3).
  • the board 21 and the dial 20 are first placed on top of one another
  • Paragraph 22 launched. Your correct orientation to each other can be secured by pins, for example. Such pins engage in corresponding recesses or notches, which are introduced on the individual components to be assembled. In a mechanized assembly, a sensor can detect the exact position of this pin and, if necessary, cause the handling device to correct the alignment of the corresponding component.
  • the spacer 19 is inserted, only the glass has to be pressed between the seal 9, so that the flat surface of the glass rests on the shoulder 24.
  • the seal 9 is inserted into the groove 25 along a slightly conical tool. Due to the shape of the tool, the seal also takes on a corresponding shape. The seal thus has a slightly larger diameter at its upper area than at its lower area.
  • the watch which has been assembled so far, can then be rotated around the floor on the clockwork support by clamping one
  • Seal which is designed as an O-ring 29, can be attached without play and releasably.
  • the base 12 which forms a kind of snap connection with the clockwork support, is pressed into the latter.
  • the elasticity of the O-ring 29 contributes to the fact that the base 12 is pressed against the clockwork carrier, as a result of which the undercuts 14 bear against the corresponding wall surface of the clockwork carrier.
  • a further clock according to the invention is shown, the basic structure of which essentially corresponds to the clock described above.
  • the support part 35 of this watch is an element produced from metal round material turning. By milling and drilling, two receptacles 36, 37 have been formed on the support member 35, in the opening for fastening one, not shown
  • Bracelet berets are inserted. 6 in particular it can be seen that the clockwork carrier 38 is also pressed into the supporting part and that the clockwork, the dial and the watch glass are arranged on shoulders or shoulders of the clockwork carrier.
