Definitions
- the invention relates to an electronic Watch with one arranged in a housing Clockwork, with a rechargeable that feeds the clockwork Power source and a charging this power source Generator, the rotor of a flywheel is drivable.
- Such a small watch in the form of a wristwatch is known from DE-A-2751 797 and has as Power source a small accumulator and one Generator, whose moving part with a through the movement of the clock actuatable inertial rotor as Flywheel is coupled.
- This flywheel is in a central point of a board, which is also the Power source carries, stored and at its edge provided with a permanent magnet.
- This Permanent magnet works with fixedly installed coils together, on the moving circle of the permanent magnet lie. The current pulses induced in this way are rectified by a rectifier circuit and to charge the small accumulator used.
- the generator the flywheel and the movement inside the case are mounted in this publication nothing said.
- the present invention is based on the object an electronic watch of the type described at the beginning Kind of train so that from generator and flywheel existing component in a simple manner, without interfering with the movement, quickly in the watch case can be mounted without the pressure sensitive electronic clockwork when assembling the watch is mechanically stressed by the mentioned component becomes; the generator and Flywheel existing component for housing and Movements of different types without constructive Change may be applicable, provided that these are Watch cases around standard cases with the same opening diameter acts.
- bottom of the watch case is part of the Module itself forms and the central pin for that Bearings of the flywheel and the generator rotor.
- module 1 has one Mounting plate 2 on the top of the Generator 3 and on the underside the flywheel 4 wearing.
- the rotor 5 of the generator and the flywheel 4 are attached to a central pivot 6, the in a ball bearing 7 of the mounting plate 2 rotatable is stored.
- the permanent magnet or the magnetized rotor 5 is from the stator 8 surrounded, which has a ring coil.
- the two output terminals of the generator are made by two spring contacts 9 formed, which in the unloaded state point diagonally outwards.
- the mounting plate 2 is with one for clamping the module in the watch case provided certain ring flange 10.
- FIGS 2 and 3 show a first embodiment a wristwatch with a module 1 Figure 1.
- the case of this watch consists of a Middle housing part 11, the top through a watch glass 13th is locked, and from a floor 12.
- a clockwork 14 is held by the middle part 11 and carries a Dial 15.
- module 1 arranged, which on its upper side Generator 3 with rotor 5 and stator 8 and on it lower side has the flywheel 4, with a screw 4a at the lower end of the pivot 6 ( Figure 1) is attached.
- the module 1 is with its ring flange 10 in a recess 11a of the Middle part 11 is used and is closed when the Housing by pressing the bottom 12 in the Middle part 11 clamped automatically.
- the Attachment of the clockwork 14 and the arrangement of the Turning 11a are chosen so that between the Clockwork 14 and module 1 there is a free space, so that the movement 14 in no way through the module 1 is mechanically loaded.
- a rechargeable one Power source preferably a rechargeable battery 16 which in the usual manner in a recess of the Clockwork 14 is arranged.
- the required Electronics or the required electronic Components are, preferably on a circuit board and / or an integrated circuit, housed in module 1, can also in a movement holder ring or housing ring, that shown in the example according to FIGS. 6 and 7 is installed.
- Figures 4 and 5 show a bottom 12, the for a second example of an otherwise not shown Small clock heard and on his up directed edge has a recess 12a, in which the module 1 with its ring flange 10 is inserted. If the watch case with this bottom 12 is closed, the ring flange 10 of the module pressed against the underside of the middle part of the housing and pinched. Again, the arrangement is like this hit that the top of module 1 where itself Rotor 5, stator 8 and spring contacts 9 are one has a certain distance from the clockwork. Likewise, the bottom has of module 1, where the flywheel 4 a certain distance from the floor 12.
- module 1 consists of the housing base 18, which is also the mounting plate forms the generator 3 with rotor 5 and stator 8 and the one arranged above the generator Inertia 4.
- a pin 19 molded or attached around which the movable Parts of module 1, namely rotor 5 and flywheel 4 are rotatably supported by means of a ball bearing 20.
- contact springs 9 With the terminals of the ring coil of the stator 8 connected contact springs 9 are bent in this case that they pass the flywheel 4 laterally protrude diagonally upwards.
- This module 1 with the bottom 18th can be pressed directly into a middle part of the housing be, as in Figure 9 using the example of a wristwatch shown.
- This watch has a central housing part 11 a lower recess 11a for module 1, one Movement holder ring 21 or housing ring which holds the movement 14 holds, has a dial 15 and a glass 13. Again the top of the module 1 with the flywheel 4 one Distance from clockwork 14.
- the rechargeable battery that is arranged as in the clock of Figure 2 is not shown.
- module 1 can with different movements and cases Design can be combined directly, provided that it is standardized housing and standard movements, that have a prescribed diameter.
- the floor can also be made of glass. Instead of a floor that can be assembled by pressing in can also a floor with screw fastening may be provided.
- the current source can also be a capacitor.
- FIG. 10 shows a small clock with a one-piece housing shell 22, in the below the module 1 with its ring flange 10 in one Turning 22a is inserted and which through above a glass 13 is closed.
- the distance to Movement 14 above is the movement retaining movement holder ring or housing ring 23, of the ring flange 10 of the Module 1 jammed.
- the dial 13 is on the edge held by a height ring 24.
- the flywheel 4 of module 1, which in turn is provided with spring contacts 9 is located below.
- the battery in the clockwork is not shown
- the spacer can also be a spacer ring be made of metal or plastic, in particular resilient plastic, exists.
- the described Housings can also be pressed on Have frosted glass.
