Definitions

  • the invention relates to a device for fastening a dial of a watch according to the preamble of claim 1.
  • the device according to the invention is intended for watches with electroluminescent dials.
  • electroluminescent dials generally have two electrodes and an electroluminescent layer in between.
  • the top electrode is transparent.
  • the electroluminescent layer is illuminated. The glow effect is visible through the transparent electrode for the watch wearer.
  • a watch with such a dial is shown in US Pat. No. 5,265,071.
  • the dial is glued to a dial carrier, which in turn is attached to the clockwork.
  • the dial carrier has a recess in its peripheral area, through which a zebra contact protruding from the clockwork passes and, due to its foam-like nature, exerts contact pressure on the underlying electrode of the dial.
  • a tab leading out of the dial, bent around the clockwork and screwed to the underside of the watch, enables contact to be made with the top electrode.
  • the present invention is therefore based on the object of providing a device which ensures a flat, uniform and permanent support of the dial on the dial carrier and simple assembly and disassembly of the unit formed from the dial and its carrier on or from a base element, such as a circuit board or a factory holding ring.
  • rivet-shaped fastening pins are provided through the dial, the dial carrier and the annular fastening means, which ensure firm cohesion.
  • the fastening pins are welded to the annular fastening means.
  • a round dial carrier 14 for example completely covering the movement retaining ring 13 and the movement 10 on this side, made of brass.
  • An electrically insulating adhesive layer 15 is applied to the dial carrier 14 and fixes a conventional, electroluminescent dial 16 on the dial carrier 14.
  • the electrical energy required to light up the dial can be supplied, for example, via two spring contacts protruding from the movement retaining ring 13 in its peripheral region.
  • the underside of the lower electrode is acted upon by one spring, while the other spring presses against the underside of the upper, transparent electrode through a cutout which leads through the lower electrode and the electroluminescent layer.
  • the springs are not shown here for the sake of clarity.
  • a supply circuit, not shown, of conventional type is provided in the work retaining ring 13, which supplies the battery which is also supplied by a battery, also not shown DC voltage converts so that an appropriate glow of the electroluminescent dial 16 is made possible.
  • the dial 16 can be switched on via a push button, not shown here, designed as a momentary switch.
  • a flat, ring-shaped fastening means made of brass hereinafter referred to as hold-down ring 17, in which, according to FIG. 1, a through hole 19 is formed in the direction of an axis 18 which runs parallel to the axis of rotation 12 .
  • the description below relates to the region of the axis 18 shown in FIG. 1, which is more clearly shown in FIG. 2 as a detail section.
  • a further through hole 20 and 21, respectively, also running in the direction of the axis 18, is provided in the dial 16 and in the dial carrier 14. Also in alignment with the axis 18, a step-shaped blind hole 22 with a lower, longer hole area 23 and an upper, shorter, somewhat larger diameter hole area 24 is also formed in the work holding ring 13.
  • a rotationally symmetrical fastening pin 25 which consists for example of brass.
  • further fastening pins 25 not shown in FIGS. 1 and 2, are provided, for which and the vicinity of which the section of FIG. 2 is also valid.
  • a total of two, opposite, or three fastening pins 25 arranged at an angular distance of 120 ° are preferably provided.
  • the representative fastening pin 25 shown in FIG. 2 has a longer, cylindrical shaft 26 which is seated in the adhesive region in the hole region 23 of the blind hole 22. At the top of this shaft 26 is a thin, annular flange 27, which finds space in the short hole area 24.
  • the flange 27 has an annular bearing surface 28 on its upper side, which is flush with the upper side the movement retaining ring 13.
  • the dial carrier 14 thus also rests on the contact surface 28 of the flange 27.
  • the fastening pin 25 has, in connection with the flange 27, a short area 29 which is located in the through hole 21 of the dial carrier 14. In the area of the adhesive layer 15, the fastening pin 25 tapers, ie the short area 29 merges into a longer area 30 with a smaller diameter.
  • This area 30 does not completely fill the through hole 20 of the dial 16, but rather creates an essentially hollow cylindrical free space 31, which ensures the electrical insulation between the dial 16 and the fastening pin 25.
  • the area 30 of the fastening pin 25 also leads through the through hole 19 of the hold-down ring 17 and opens into a rivet head 32 shown flattened, which finds space in an enlarged area 33 of the through hole 19, so that the rivet head 32 is sunk into the hold-down ring 17 and the latter still has a flat surface 34.
  • the rivet head 32 On its underside, the rivet head 32 has a contact surface 35 which rests on the hold-down ring 17.
  • the dial carrier 14, dial 16 and hold-down ring 17 are first riveted by means of the fastening pins 25 to form a compact unit, which is referred to below as the dial unit.
  • This dial unit can be temporarily stored or immediately put on as a whole on the clockwork 10 or the movement retaining ring 17, the shafts 26 of the fastening pins 25 being held in the blind holes 22 of the movement retaining ring 13.
  • a sufficiently secure anchoring of the hold-down ring 17 in the work holding ring 13 is possible with two to three fastening pins 25.
  • a corresponding number of holes 19 to 22 is of course provided.
  • the dial carrier 14, the hold-down ring 17 and the fastening pins 25 are made of brass, the electrically insulating adhesive layer 15 and the hollow cylindrical free space 31 prevent the two electrodes of the dial 16 from short-circuiting with one another.
  • the electrical energy required to light the dial is supplied via two spring contacts protruding from the movement retaining ring 13.
  • FIG. 3 shows another embodiment, designated 17 ', of the hold-down ring 17 shown in FIGS. 1 and 2.
  • several, advantageously two to three fastening pins 25 ' are welded to the hold-down ring 17', similarly as is known from conventional dials and their dial feet, so that the hold-down ring 17 'has a flat surface 34'.
  • 3 shows only a single, representative fastening pin 25 ', which is rotationally symmetrical with respect to an axis 18', which corresponds to the axis 18 shown in FIGS. 1 and 2, and has a cylindrical shaft 26 ', which is is largely in the longer hole area 23 of the movement retaining ring 13.
  • the fastening pin 25 'tapers ie the shaft 26' merges into a cylindrical area 30 'with a smaller diameter.
  • the area 30 'does not completely fill the through hole 20 of the dial 16, but rather, as in the exemplary embodiment of FIGS. 1 and 2, creates a hollow cylindrical free space 31' which ensures the electrical insulation between the dial 16 and the fastening pin 25 '.
  • a rotatable dial latch 42 which is already known per se, is arranged directly next to the fastening pin 25'.
  • the dial latch 42 has a head 43 which is partially concentric with the axis 41 arranged cutting edge 44 is surrounded, as well as a first cylindrical part 45 and a second cylindrical part 46, which is somewhat smaller in diameter.
  • the diameter of the first cylindrical part 45 enables the dial bolt 42 inserted into the bore 40 to be securely seated.
  • the head 43 also has a Slot 47 for attaching a screwdriver-like tool, not shown.
  • a part of the head 43 and the cutting edge 44 is severed along a cutting plane, preferably parallel to the axis 41, forming a cutting surface 48. In Figure 3, this cut surface 48 is shown on the side facing away from the fastening pin 25 '. In this rotational position of the dial bolt 42, the cutting edge 44 penetrates the fastening pin 25 'and anchors it in the direction of the axis 18'. Such anchoring is provided for each fastening pin 25 '.

However, it is also possible to inject the whole from a single piece of plastic. In addition to a low manufacturing price, this solution also has the advantage that the fastening pins 25 'between the electrodes of the dial 16 cannot produce a short circuit, as a result of which hollow-cylindrical free spaces 31 can be dispensed with and the requirement made of the adhesive layer 15 with regard to electrical insulation capability no longer applies.
  • the electrode on top can be contacted directly by the hold-down ring 17 ', at least one fastening pin 25' and the associated blind hole 22, which is designed, for example, as a female contact socket, ensuring the electrical connection between the hold-down ring 17 'and the supply circuit (not shown) in the works holding ring 13.
