    Technical field
    The present invention relates to the construction of a power reserve display device, and in particular to a construction of a power reserve display device for wristwatches, which can display the remaining amount of drive energy stored by a winding spring of a power reserve display wheel on the power reserve display, so that the power reserve display device has a relatively simple structure for practical use can be produced.
    State of the art
    As is known, a mechanical wristwatch receives its drive energy from a mechanical drive energy store. The drive energy for the drive, which is required to run the wheels, is supplied by the barrel, which forms with a clockwork and a winding spring. When the user wears a wristwatch on one hand, the drive energy is generated by winding the winding spring, the stored potential drive energy being released in a controlled manner and converted into a rotary movement of the display device. For this reason, a wristwatch can always run constantly when worn on one hand.
    At the same time, when the user wears the watch, the swinging and shaking of his arm also causes the runner to swing in the watch so that the drive energy of the runner can be stored in the run by a transmission device. Many wristwatches use precious metals to make the runner in order to increase the weight of the runner while still being able to maintain the efficiency of the elevator in a small volume. The drive energy is generated by winding the spring, so that the watch can continue to work.
    The power reserve display shows the remaining time until a mechanical watch stops on a display window of a dial and thus provides information as to whether or when the watch has to be wound up again, for example by means of an elevator crown to lift the winding spring. The power reserve or duration is the time that a watch runs after being wound until it has to be wound again.
    A mechanical wrist watch, regardless of whether it works with manual or automatic winding, the drive energy is generated by winding the winding spring. Since the stored drive energy is relatively limited, the user must wind up the clockwork in good time using an elevator crown so that the clock can be prevented from coming to a standstill.
    Towards the middle of the 19th century, the industrial manufacture of pocket watches each used a power reserve indicator to indicate the release status of the stored drive energy. Pocket watches have largely gone out of fashion today and have been replaced by increasing wristwatches with a power reserve indicator. The power reserve display shows the time remaining until a mechanical watch comes to a standstill and thus provides information as to whether or when the watch has to be wound again. The power reserve indicator makes it possible to prevent the watch from stopping by additional manual winding. Power reserve indicators are used for almost all mechanical wristwatches these days.
    Due to the structure of the power reserve indicator, the prior art consists in adding an escape wheel in a system by an winding spring so that it can be driven in accordance with the tensioning or relaxation of the winding spring, with the remaining time until a mechanical watch comes to a standstill can be displayed on a display window of a dial and thus provides information as to whether or when the watch has to be wound again.
    The power reserve indicator is shown on the dial of a wristwatch. The power reserve display shows the time remaining until a mechanical watch comes to a standstill and thus provides information as to whether or when the watch has to be wound again. The power reserve display enables the release status of the stored drive energy with pointers and scales with graduation with the lettering UP (HIGH) - for the fully wound - and DOWN (LOW) - for the fully expired clockwork or with hours or days - indication of a potential drive energy display on the dial.
    As is known, a conventionally known power reserve indicator is built on a drive wheel and the hour, minute and second hands are arranged coaxially in the middle of the area of the power reserve indicator. However, such a construction of the power reserve display device is complicated, so that all the components cannot be easily assembled in the small housing and also entails high manufacturing costs.
    In view of the above-mentioned problems, the inventor of the present invention carried out extensive research and experimentation, and finally provides a technically feasible solution to overcome the problems of the prior art.

    The technical features, contents, advantages and effects of the present invention will become apparent from the detailed description of a preferred embodiment with the following accompanying drawings.
    As can be seen from FIGS. 1 to 4, the construction according to the invention of a power reserve display device for wristwatches essentially has a housing 10, a display gear train 20, a clock spring 22, a power reserve display wheel 30, an armature 40 and an elevator shaft 50.
    The housing 10 is formed cylindrically hollow with a receiving space and a work plate 11, wherein a bore of the display gear 14 is provided in the middle of the work plate 11 and a mounting hole 12 is attached to one side of the work plate 11. In addition, a locking pin 13 is excellently arranged close to the bore of the indicator gear train 14 of the work plate 11, a bore of the power reserve indicator wheel 15 being located on the outer circumference of the locking pin 13.
    The display gear train 20 is continuously connected to the bore of the display gear train 14 of the work plate 11. In addition, the shaft formed on the underside of the display gear train 20 and the gear transmission are connected via a transmission located in the wristwatch. Since the functional principle and built-in parts and components of a transmission system are already known from the prior art, they are therefore not described and illustrated in more detail here. Furthermore, a spring core shaft 21 is excellently arranged above the display gear train 20, whereby the hour hand, the minute hand and the second hand can each be coupled to the upper edge of the spring core shaft 21. Furthermore, a clock spring 22 is attached below the spring core shaft 21, the clock spring 22 being stamped and formed from sheet metal and having a fastening hole in the middle thereof, an anchor pallet 23 being arranged symmetrically on both sides of the clock spring 22.
    The power reserve indicator wheel 30 (also known as “escape wheel / escapement wheel) is continuously connected to one another with the bore of the power reserve indicator wheel 15 of the work plate 11. In addition, an arcuate locking recess 31 is provided on one side of this power reserve indicator wheel 30 and an arcuate recess of an internal toothing 32 is provided on the other side of this power reserve indicator wheel 30. Furthermore, an arcuate toothing 33 is provided on one side of the recess of an internal toothing 32. Furthermore, a drive shaft of the power reserve indicator wheel 34 with a spiral roller 35 is excellently arranged in the middle of the power reserve indicator wheel 30, and a pointer can be coupled to the upper edge of the drive shaft of the power reserve indicator wheel 34 to indicate the power reserve status. Since the manufacturing method for a pointer of a wristwatch is already known from the prior art, it is therefore not described and illustrated in detail here.
    The anchor 40 is stamped and formed from sheet metal, with a mounting hole 41 being made on one side of its one horizontal section, with an arcuate anchor pallet 42 being excellently arranged on the other side of its one vertical section. In addition, the armature 40 is attached by means of a fastening pin 43 to a fastening hole 41 located on one side of its horizontal section and continuously connected to the fastening hole 12 of the work plate 11.
    The elevator shaft 50 extends from the center of the elevator spring 51 upwards, specifically through the work plate 11 in the middle of the elevator spring 51. Since the manufacturing method for a winding spring 51 of a wristwatch is already known from the prior art, it is therefore not described and illustrated in detail here. In addition, a pointer position mechanism 52 is coupled to the upper part of the elevator shaft 50, which is formed obliquely with two anchor pallets. Furthermore, the pointer setting mechanism 52 is provided with a recess of an internal toothing 32 located on one side of the power reserve indicator wheel 30 and is further brought into contact with the curved toothing 33. In addition, the locking pin 13 is provided through the locking recess 31 located on the other side of the power reserve indicator wheel 30. Furthermore, the right-angled anchor pallet 42 of the anchor 40 is brought into contact with the external toothing of the power reserve indicator wheel 30. Furthermore, a clock spring 22 is attached below the spring core shaft 21 of the indicator gear train 20, the anchor pallet 23 located on one side of the clock spring 22 being arranged in accordance with the anchor pallet 42 located on the section of the anchor 40 which is formed at a right angle, namely by 180 degrees symmetrically with the External toothing of the power reserve indicator wheel 30 is brought into contact to assemble a power reserve indicator for wristwatches.
    As described above, a power reserve display device for wristwatches according to the present invention has the following properties: The transmission force of the power reserve display device for wristwatches according to the invention arises from a winding spring located in a wristwatch, which is driven by a toothed gear, so that the indicator gear train 20 in Can be rotated clockwise, wherein the stored drive energy is gradually released from the winding spring 51, so that the power reserve indicator wheel 30 can be rotated counterclockwise by the cooperation of a pointer setting mechanism 52 of the elevator shaft. After the upper arcuate end of the locking recess 31 located on one side of the power reserve indicator wheel 30 engages with the locking pin 13, the winding spring must be re-opened. It is particularly advantageous that the drive shaft of the power reserve indicator wheel can be coupled to one another so that the remaining amount of the drive energy stored by the winding spring can be displayed on the power reserve display, so that the power reserve display device according to the invention can be manufactured with a relatively simple structure for practical use.
    While only a selected preferred embodiment has been used to illustrate the present invention, it will be apparent to those skilled in the art from this description that various changes and modifications can be made therein without departing from the scope of the invention as set forth in FIG the attached protection claims are defined. In addition, the foregoing description of the embodiments of the invention is provided for purposes of illustration only and is not intended to limit the present invention, which is defined by the appended claims and their equivalents.
