Definitions
- This invention relates generally to mechanisms for winding self-winding mechanical watches.
- the invention describes an automatic watch-winding apparatus for keeping a self-winding watch wound during periods of non-use.
- Self-winding watches have been available for many years and are known for keeping a mechanical wrist watch wound while it is worn by a user.
- the winding mechanism of a self-winding watch typically comprises a rotary pendulum or rotor that is connected through a gear reduction system to a mainspring adapted to drive the escape mechanism of the watch.
- the pendulum pivots about a bearing and is generally capable of rotating a full 360 degrees.
- the random movements of the wearer cause the rotor to oscillate back and forth, or to spin completely about its axis, to wind the mainspring.
- the mainspring When completely wound, the mainspring will generally have sufficient energy to run the watch for up to about 12 to 48 hours, depending on the particular type of watch. Some watches can store enough energy to run eight days.
- the daily use of the watch will normally be sufficient to maintain continuous operation overnight, even if no winding takes place at night.
- a person it is not uncommon for a person to own more than one watch, for use on different occasions such as sporting events, formal attire, or office attire.
- the energy in its mainspring will completely dissipate.
- a self-winding watch cannot, as can a manually wound watch, be fully rewound in a few seconds by the user.
- the task of maintaining multiple watches wound and operating is an inconvenience, and may also include resetting the time on the watch each time the spring runs down.
- the owner of a self-winding watch may rely on a watch winder to wind the watch during periods of non-use.
- a watch winder is a powered device designed to keep a self-winding watch wound, thereby eliminating the need for manual rewinding and resetting.
- Prior art watch winders typically include a power driven spindle or turntable adapted to hold and rotate the watch about an axis coincident with its center. During rotation, the pendulum or rotor of the watch will hang downward under gravity, and the watch will rotate about the stationary rotor.
- an electronic circuit is provided to start and stop the movement of the spindle.
- the control circuit of a prior art watch winder is configured to permit the spindle to rotate for a set period of time.
- a further problem may be encountered with prior art watch winders if, for example, a user places his watch in a winder and starts it running intending to leave the watch in the winder for, say, 36 hours before he wears it. If the watch takes only 12 hours to wind, then 24 hours may be spent winding a fully wound watch. This is an inefficient use of battery energy, and may even be mechanically undesirable for the watch. Alternatively, under the same circumstances, if the user places his watch in a winder knowing it is fully wound, then 36 hours may be spent winding a fully wound watch, to even greater wasteful effect. The prior art has not sufficiently taken into account such questions of battery efficiency. Further, the prior art has not adequately provided for various aspects of convenient use, such as where different watch types have mechanisms with different winding requirements.
- a first spring mechanism may be dedicated to running the hour and minute hands of the watch, while a second spring mechanism may be dedicated to running the calendar and the lunar phase indicator.
- a second spring mechanism may be dedicated to running the calendar and the lunar phase indicator.
- they may be configured to be wound in opposite directions.
- it may be necessary for a watch-winder to rotate, alternately, clockwise and counterclockwise in order to wind both spring mechanisms.
- some self-winding watches are only wound by the rotor rotating in one direction, either clockwise, or anticlockwise, so that alternating the direction of rotation may actually amount to a waste of battery energy in the case of such watches.
- the present invention provides an improved watch winder.
- the present invention provides a method and apparatus for winding a watch in such a manner that will save power, at the same time as providing greater assurance that the watch will be fully wound at the completion of the winding process when the user decides to wear the watch.
- the invention provides for greater ease of use and adaptability in a watch winder in that the invention caters to various types of self-winding watches with differing winding mechanisms. It also allows the user to more easily insert the watch on the winder.
- the watch winder of the present invention includes a rotatable turntable adapted to rotate a self winding watch, a motor configured to rotate the turntable, and an electronic circuit to control the motor, the circuit being configured to commence rotation of the turntable after first introducing a period of delay after the circuit is activated. Such delay facilitates ease of use by the user, and efficiency of battery energy consumption.
- Another feature of the invention includes the capability of the electronic circuit to identify each rotation of the turntable, and to count the total number of rotations.
- the electronic circuit may be configured to automatically pause rotation of the turntable after a predetermined number of rotations, whereafter rotation may automatically recommence.
- the circuit may be further configured to predetermine the direction of rotation of the turntable, so that it may reverse directions after each pause, or maintain a constant clockwise direction, or a constant counterclockwise direction.
- the electronic circuit may be manually adjusted, prior to use of the winder, to variably predetermine the number of rotations between pauses, and the length of the pauses.
- the number of rotations and the length of the pauses may be preprogrammed in the circuit, without the capability of manual adjustment.
- Another aspect of the present invention is directed to a cuff configured to allow a wrist watch to be easily mounted upon it, for insertion into the turntable of the watch winder.
- the cuff includes an inner core of open cell foam and a covering of porous material, both core and material being chosen for their characteristic of high porosity, allowing the rapid ingress and escape of air when the cuff is compressed, and when compressive force is released. This quality allows the cuff to be rapidly compressed to facilitate mounting and demounting of a wrist watch.

- An LED, or light emitting diode 47 may also be installed on the control panel to indicate the status of the winder. For example, a green light may indicate that the winder is activated, and a red light may indicate a low battery condition.
- a lockable drawer 48 adapted to hold DC batteries, slides out of the rear wall of the exterior housing 32 .
- a fixed length ribbon (not shown), attached to a fixed point inside the interior of the housing at one end and to the drawer at the other end, prevents the drawer from being removed from the housing in the event it is pulled out without restraint.
- a DC jack (not shown) is also mounted on the rear exterior wall of the housing to receive an input plug from an optional AC/DC converter, connected to a 110 or 220 volt AC source (not shown).
- the watch winding apparatus 30 of the present invention includes, positioned within the exterior housing 32 , an interior housing 60 , as exemplified in FIGS. 2-6 .
- the interior housing 60 is configured to contain the rotatable turntable 38 with its cuff 39 (not shown in FIGS. 2-6 ) for holding a watch on the turntable, a drive assembly 64 ( FIG. 4 ) for rotating the turntable, an electronic circuit 66 ( FIG. 4 ) for controlling the drive assembly, and the control switches 44 , 46 for controlling the turntable via the circuit 66 .
- the interior housing 60 may be formed of moldable plastic to comprise a back wall 68 to which there are attached two vertical side walls 70 , 72 , a top wall 74 , and a bottom wall 76 to define an interior space 78 .
- the interior space 78 of the interior housing is sealed by the interior front wall 40 of the external housing 32 .
- the turntable 38 includes a circular base 80 and a cylindrical sidewall 82 , giving it a drum-like shape with an interior bore 84 open at one end.
- a toothed large gear wheel 86 having a diameter approximately the same as the base 80 is attached directly to the base.
- the turntable 38 is rotatably attached to the interior housing 60 through the large gear wheel 86 which is connected to a bearing 88 ( FIG. 3 ) mounted on the back wall 68 of the interior housing.
- the drive assembly 64 comprises a small electric motor 90 which transmits rotational movement to the turntable 38 via a pulley 92 and intermediate gears 94 , 96 configured to mesh with the large gear 86 on the turntable.
- Power for the motor is supplied either by closed cell battery, or by a power cord. Where a power cord is used, with an AC/DC adapter, it plugs into a conventional 110 volt or 220 volt AC outlet. It is preferable to use a motor selected for low power use, while still having the capability to keep proper motion for a watch up to 350 grams, which is about the heaviest watch currently obtainable.
- the interior housing 60 may include a plurality of cantilever supports 102 extending from the back wall 68 into the interior space 78 , arranged in relation to each other in a generally triangular pattern.
- Each support 102 includes a rotatable annular bearing 104 at a terminal end portion of the support, preferably made of rubber or a similar resilient compound.
- Each support 102 is positioned to permit each bearing 104 to abut the outer surface of the cylindrical wall 82 of the turntable 38 and provide a diametrically inward force to stabilize the turntable against lateral movement, particularly when the turntable is being powered by the motor.
- Each annular bearing 104 is preferably positioned to protrude laterally beyond the axial shadow of its associated cantilever support 102 , to prevent any interference between turntable 38 and cantilever support 102 , allowing the turntable to butt only against the bearings 104 .
- This particular configuration of cantilever supports with resilient bearings provides for smooth, quiet rotation of the turntable.
- a self-winding watch 41 is mounted on a cylindrically shaped cuff 39 ( FIG. 1B ) which is then inserted into the bore 84 of the turntable 38 so as to allow the face of the watch to protrude on the outside of the front wall 40 of the housing 32 , and to allow the watch to be rotated by the turntable in the plane of the hands of the watch.
- Control of the turntable's rotation is achieved by the electronic circuit 66 ( FIG. 4 ), which may include a conventional programmable microprocessor capable of receiving input signals, and of generating output signals to achieve control of the turntable.
- the microprocessor may be configured to activate the motor 90 , to determine in which direction the motor will rotate, to count and to limit the number of rotations executed by the turntable 38 , to interrupt rotation of the turntable for interspersed periods of time, and/or to terminate rotation of the turntable entirely after a number of rotations until the circuit 66 is manually reactivated. Operation of the control circuit 66 through the microprocessor is achieved using, for example, switches 44 , 46 located on the front wall 40 of the housing 32 .
- control circuit 66 is configured to count the number of revolutions turned by the turntable 38 .
- a light-reflective film 112 formed, for example, as a silver or copper coated plastic film, may be fixed to the outer surface of the turntable's cylindrical wall 82 such that less than 360 degrees, preferably 180 degrees, of the wall circumference is covered by the film 112 ( FIG. 6 ).
- an infrared reflective sensor 114 is positioned proximate the cylindrical wall 82 such that, when the turntable rotates through 360 degrees, light emitted from the infrared sensor is reflected from the film 112 only throughout the rotational angle wherein the film is present on the outer wall 82 , but not where the film is absent.
- the resulting break in reflected light each revolution is detected by the infrared sensor and is interpreted by the circuit 66 as marking the passage of a single revolution. Additionally, the circuit 66 is configured to have a memory which maintains a cumulative count of the number of rotations executed by the turntable. As indicated previously, setting the motor to run for a set period of time may not be sufficient to fully wind the watch, especially where the watch is a large or heavy watch that may cause the speed of rotation to be slowed or where there is a fluctuation in the power supply.
- a suitable infrared reflective sensor for detecting the completion of a rotation by the turntable is a subminiature photointerrupter made and supplied by Sharp, having model number GP2S40.
- the circuit 66 may be configured to automatically delay the start of the turntable's rotation, so that, when the circuit is initially activated through the switches 44 , 46 rotation of the turntable commences only after a period of time. In one preferred embodiment, the delay is between 8 and 16 hours, preferably about 12 hours. The delay in commencing winding avoids the wasteful effect on the batteries of winding a watch that is already fully wound when placed on the winder after a day's use, and then going on to spend hours further winding it. The delay allows the watch to run down to some extent before the winding commences. In another aspect of the invention, the circuit 66 may be configured to provide a short delay in starting rotation, of as little as ten seconds, preferably between 5 and 15 seconds.
- the low battery warning indicator will be functioning even when the switch 44 is in the “off” position.
- the switch 44 is in the “mode 1” position (short delay) or “mode 2” position (long delay)
- both the power indicator (green) and the warning indicator (red) will be operational.
- the warning indicator also will be flashing when a locked condition of the turntable is detected.
- the circuit 66 may be further configured to pause the motor once a pre-programmed number of rotations has been achieved, and to resume rotation after the pause, continuing with this pattern of rotation and pause until the winder is manually turned off.
- the circuit 66 may be configured to automatically terminate the cycles of rotation and pause for a period of time after a predetermined total number of rotations has been executed, preferably, in one embodiment, between 600 and 1200 rotations.
- the number of rotations will be set to correspond to the average number needed to fully wind most self winding watches. While the number can vary depending upon watch brand, numbers of complications, and the like, in practice, it has been found that about 90° rotations is optimal for most watches
- the circuit may be configured to automatically cause the turntable to be rotated between 100 to 200 rotations, preferably about 150 rotations in a twenty minute period, before pausing for between 30 and 90 minutes, preferably 70 minutes, and then to repeat this cycle several times, preferably six times, before automatically turning off for an extended delay period (preferably about 15 hours).
- This combination is believed to be optimal in preservation of battery energy.
- a minimum of at least five rotations per cycle is needed for winding watches with certain unique complication.
- the range of rotations is between 50 and 2500 rotations in each cycle, to accommodate watches with unusual winding systems.
- the circuit 66 may be configured to allow the user to manually adjust the circuit, prior to use of the winder, to variably alter and predetermine the number of rotations in each set of rotations and the length of the pause period between sets of rotations.
- the circuit 66 may be configured to allow the user, prior to use, to cause the direction of each succeeding set of rotations to automatically either reverse direction, or to be all clockwise, or to be all counter-clockwise, to suit the needs of the particular watch as previously described, controlled by switch 46 which may have a three position setting—clockwise, alternating directions, anti-clockwise.
- the switch 46 may be set by the user to select between three possible modes of operation.
- a first mode of operation the turntable will rotate clockwise for 150 revolutions, and then stop, representing one rotation cycle.
- the total time taken for this one rotation cycle will be about 1.5 hours, with about 20 minutes of rotation time and about 70 minutes of pause time.
- This rotation cycle then repeats six times, and then stops for a long stop period, preferably about 15 hours.
- the total time taken from the start of rotation to the end of the long stop period is about 24 hours. It has been found that the periods 20 minutes for rotation and 70 minutes for pause enables the winder to wind most watches, while using minimal power. Further, the number of 150 rotations allows the winder to cover the motion requirements for most watches, while using a minimum of battery power.
- a second mode of operation the operation is similar to that of the first mode, except that the rotation is in the counter-clockwise direction.
- the turntable will start rotating in a clockwise direction for 150 revolutions, then rotate for another 150 revolutions counterclockwise, then stop, representing one rotation cycle.
- the time taken for this one cycle is about 1.5 hours, with 40 minutes of rotation time (20 minutes clockwise and 20 minutes counterclockwise) and 50 minutes of pause time.
- This rotation cycle then repeats six times, and then stops for a long stop period of about 15 hours, for a total elapsed time from start of rotation to the end of the long stop period of about 24 hours.
- any of these three modes of operation can be used in combination with one of the two start-delay modes of operation described above. If either the short delay or long delay is selected, the delay will be disabled after the first 24 hour cycle is completed.
- the speed of rotation of the turntable and the duration of the pause time, or both are automatically adjusted and controlled in response to turntable speed to allow for precise time cycle durations, especially where the power source is fluctuating or where a heavy watch is being used.
- the cuff 39 of the watch winder typically has a generally cylindrical form sized to be inserted into the bore 84 of the turntable. Edges of the cuff may be shaved off to permit a watch to be mounted thereon and still to allow the cuff to be inserted into the cylindrical bore 84 .
- the cuff 39 may be configured to be rapidly compressible and decompressible in an axial direction. This feature may facilitate attachment of the watch to the cuff in that the watch strap may be clasped or buckled closed first, whereafter the compressed cuff may be inserted through the closed strap of the watch.
- the cuff 39 of the present invention may be formed of an internal cylindrical block of open cell foam 120 having the overall desired shape of the cuff.
- the foam block 120 may be sandwiched between two rigid plates 128 , made preferably from rigid hardboard, the resulting combination being enclosed in a porous material cover 122 which is stitched or glued closed at the seams.
- the combination of open cell foam and porous material gives the cuff the desirable characteristic of being rapidly compressible and decompressible, because both the foam and the fabric will allow air to rapidly escape when the cuff is compressed by hand, and to enter the cuff allowing it to rapidly return to its original shape when the compressing force is removed.
- Additional features of the cuff may include flexible pull tabs 124 , made of leather or similar material, set in the center of the circular face 125 of the cuff, to allow the user to take hold of and remove the cuff when its edges are inaccessibly located within the bore of the turntable.
- Rigid push tabs 126 may be set on the circumferential edges of the cuff, to permit the user to take hold of the cuff and introduce it into the bore of the turntable when a watch is located on the cuff, making the pull tabs 124 inaccessible.
- the operation of the watch winder can be made controllable via a hand-held infrared remote control device, in lieu of or in addition to the switches 44 , 46 .
- an LCD readout with a built in clock can be provided to allow the user to visibly observe and set the start time and end time, rotation direction and duration.
- Voice activated control of the functions is yet another modification, as is audible notification of functions to the user.
- FIG. 11 depicts the overall circuit, broken into sub-circuits showing their interrelation to each other.
- the microprocessor, bearing reference numeral 200 is shown at the center of the circuit 66 .
- Sub-circuits 212 through 221 are shown in larger scale in FIGS. 12 through 21 respectively.
- a suitable microprocessor is the Holtek model HT46R22, 8 bit programmable microcontroller, which is designed for A/D applications, low power consumption, and has timer/event counter capabilities.
- Sub-circuit 212 shown in FIG. 12 is the motor control circuit comprising four transistors, 230 , 232 , 234 and 236 .
- the direction of the motor is controlled by the microprocessor which sends signals via four direction connectors 238 , 240 , 242 , 244 , so that, for example, when diametrically opposite transistors 230 and 236 are off, and transistors 232 and 234 are on, current flows from line 246 to ground 248 through motor 250 (numeral 90 in mechanical Figures) from right to left, as illustrated in the drawing, causing the motor to turn in a first direction.
- motor 250 number of 90 in mechanical Figures
- sub-circuit 213 shows the operation of the infrared photointerrupter 260 comprising, a phototransmitter 262 and a photoreceiver 264 .
- rotation of the turntable 38 past the photointerrupter causes light reflective film 112 to pass by proximate the photointerrupter.
- Light emitted from transmitter 262 is reflected from the film 112 and perceived by receiver 264 as an energy signal, but when the film is interrupted receiver 264 registers the break in energy signal and communicates this break to processor 200 via line 280 by switching off transistor 266 .
- transistor 266 is switched on again until later interrupted.
- Each interruption is registered and counted by the program memory in the processor 200 for use in controlling the rotation of the motor, as set forth above, through the microprocessor 200 and sub-circuit 212 .

In yet another aspect, the watch winder may be configured to be manually adjustable, to variably predetermine before use, the number of rotations to be executed by the turntable and the length of any pause between rotations.
Description
- This application is a divisional of, and claims priority to, U.S. patent application Ser. No. 10/845,463, filed May 12, 2004, the contents of which are incorporated herein by reference in its entirety.
- 1. Field of the Invention
- This invention relates generally to mechanisms for winding self-winding mechanical watches. In particular, the invention describes an automatic watch-winding apparatus for keeping a self-winding watch wound during periods of non-use.
- 2. General Background and State of the Art
- Self-winding watches have been available for many years and are known for keeping a mechanical wrist watch wound while it is worn by a user. The winding mechanism of a self-winding watch typically comprises a rotary pendulum or rotor that is connected through a gear reduction system to a mainspring adapted to drive the escape mechanism of the watch. The pendulum pivots about a bearing and is generally capable of rotating a full 360 degrees. When the watch is worn, the random movements of the wearer cause the rotor to oscillate back and forth, or to spin completely about its axis, to wind the mainspring. When completely wound, the mainspring will generally have sufficient energy to run the watch for up to about 12 to 48 hours, depending on the particular type of watch. Some watches can store enough energy to run eight days. In any event, the daily use of the watch will normally be sufficient to maintain continuous operation overnight, even if no winding takes place at night. However, it is not uncommon for a person to own more than one watch, for use on different occasions such as sporting events, formal attire, or office attire. Thus it will be appreciated that if one watch in a collection of watches is not worn for a few days, the energy in its mainspring will completely dissipate. Once the spring is unwound, a self-winding watch cannot, as can a manually wound watch, be fully rewound in a few seconds by the user. The task of maintaining multiple watches wound and operating is an inconvenience, and may also include resetting the time on the watch each time the spring runs down. Thus, the owner of a self-winding watch may rely on a watch winder to wind the watch during periods of non-use.
- A watch winder is a powered device designed to keep a self-winding watch wound, thereby eliminating the need for manual rewinding and resetting. Prior art watch winders typically include a power driven spindle or turntable adapted to hold and rotate the watch about an axis coincident with its center. During rotation, the pendulum or rotor of the watch will hang downward under gravity, and the watch will rotate about the stationary rotor. In certain prior art winders, an electronic circuit is provided to start and stop the movement of the spindle. Yet, a number of problems are encountered in the prior art. Typically, the control circuit of a prior art watch winder is configured to permit the spindle to rotate for a set period of time. This may be unproblematic for most self-winding watches, but where the watch is large or heavy, the weight of the watch may cause the powered winding mechanism to slow down, resulting in the watch being not completely wound after the spindle ceases turning. Further, some watch winders provide more than one spindle to run off a single DC battery or power source. When more than one spindle is being powered, the speed of rotation of both spindles may be slower than when only one spindle is being powered off the same power source. These factors introduce problems for watch winding mechanisms configured to run for a set period of time. Power fluctuations, as well as battery strength, can also affect the speed of rotation.
- A further problem may be encountered with prior art watch winders if, for example, a user places his watch in a winder and starts it running intending to leave the watch in the winder for, say, 36 hours before he wears it. If the watch takes only 12 hours to wind, then 24 hours may be spent winding a fully wound watch. This is an inefficient use of battery energy, and may even be mechanically undesirable for the watch. Alternatively, under the same circumstances, if the user places his watch in a winder knowing it is fully wound, then 36 hours may be spent winding a fully wound watch, to even greater wasteful effect. The prior art has not sufficiently taken into account such questions of battery efficiency. Further, the prior art has not adequately provided for various aspects of convenient use, such as where different watch types have mechanisms with different winding requirements.
- Problems can be encountered in that certain self-winding watches may have a plurality of spring mechanisms, or so-called “complications,” dedicated to running separate features of the watch. For example, a first spring mechanism may be dedicated to running the hour and minute hands of the watch, while a second spring mechanism may be dedicated to running the calendar and the lunar phase indicator. Where such separate spring mechanisms are included, they may be configured to be wound in opposite directions. Thus, it may be necessary for a watch-winder to rotate, alternately, clockwise and counterclockwise in order to wind both spring mechanisms. However, some self-winding watches are only wound by the rotor rotating in one direction, either clockwise, or anticlockwise, so that alternating the direction of rotation may actually amount to a waste of battery energy in the case of such watches. Furthermore, in the prior art, certain known watch winders rotate only a single revolution in one direction and then pause for a period of approximately a minute before rotating a single revolution in the other direction to be followed by another pause of approximately one minute, and so on, thus repeating the pattern until the unit is deactivated. This pattern of intermittent operation with frequent starts and stops, while adequate to wind many self winding watches, has the disadvantage of resulting in an inefficient use of stored battery power.
- Thus, a need exists for an improved watch winder that will address the needs of the prior art. It is believed that the present invention fulfills all of these needs.
- Briefly, and in general terms, the present invention provides an improved watch winder. In particular, the present invention provides a method and apparatus for winding a watch in such a manner that will save power, at the same time as providing greater assurance that the watch will be fully wound at the completion of the winding process when the user decides to wear the watch. The invention provides for greater ease of use and adaptability in a watch winder in that the invention caters to various types of self-winding watches with differing winding mechanisms. It also allows the user to more easily insert the watch on the winder.
- More specifically, and in a presently preferred embodiment, by way of example, and not necessarily by limitation, the watch winder of the present invention includes a rotatable turntable adapted to rotate a self winding watch, a motor configured to rotate the turntable, and an electronic circuit to control the motor, the circuit being configured to commence rotation of the turntable after first introducing a period of delay after the circuit is activated. Such delay facilitates ease of use by the user, and efficiency of battery energy consumption.
- Another feature of the invention includes the capability of the electronic circuit to identify each rotation of the turntable, and to count the total number of rotations. The electronic circuit may be configured to automatically pause rotation of the turntable after a predetermined number of rotations, whereafter rotation may automatically recommence. The circuit may be further configured to predetermine the direction of rotation of the turntable, so that it may reverse directions after each pause, or maintain a constant clockwise direction, or a constant counterclockwise direction.
- In another embodiment, the electronic circuit may be manually adjusted, prior to use of the winder, to variably predetermine the number of rotations between pauses, and the length of the pauses. In yet a further embodiment, the number of rotations and the length of the pauses may be preprogrammed in the circuit, without the capability of manual adjustment.
- Another aspect of the present invention is directed to a cuff configured to allow a wrist watch to be easily mounted upon it, for insertion into the turntable of the watch winder. The cuff includes an inner core of open cell foam and a covering of porous material, both core and material being chosen for their characteristic of high porosity, allowing the rapid ingress and escape of air when the cuff is compressed, and when compressive force is released. This quality allows the cuff to be rapidly compressed to facilitate mounting and demounting of a wrist watch.

reference number 30 will be described. - In a preferred embodiment as shown in
FIGS. 1A and 1B , awatch winder 30 has a rectangular sidedexterior housing 32 including anexterior front cover 34 that opens downwardly about abottom hinge 36 to expose aturntable 38 mounted centrally on an interiorfront wall 40. Acylindrical cuff 39 is provided, configured to be removable from the turntable to permit awatch 41 to be mounted on the cuff, so that the cuff and watch combination may be installed on theturntable 38. Thefront cover 34 may include a glass or plastictransparent window 42 for viewing the contents of the housing. Also mounted on the interiorfront wall 40 arecontrol switches 44, 46 (46 not visible inFIGS. 1A and 1B ) for controlling the operation of theturntable 38. An LED, or light emitting diode 47 (FIG. 2 ) may also be installed on the control panel to indicate the status of the winder. For example, a green light may indicate that the winder is activated, and a red light may indicate a low battery condition. Alockable drawer 48, adapted to hold DC batteries, slides out of the rear wall of theexterior housing 32. A fixed length ribbon (not shown), attached to a fixed point inside the interior of the housing at one end and to the drawer at the other end, prevents the drawer from being removed from the housing in the event it is pulled out without restraint. A DC jack (not shown) is also mounted on the rear exterior wall of the housing to receive an input plug from an optional AC/DC converter, connected to a 110 or 220 volt AC source (not shown). - The
watch winding apparatus 30 of the present invention includes, positioned within theexterior housing 32, aninterior housing 60, as exemplified inFIGS. 2-6 . Theinterior housing 60 is configured to contain therotatable turntable 38 with its cuff 39 (not shown inFIGS. 2-6 ) for holding a watch on the turntable, a drive assembly 64 (FIG. 4 ) for rotating the turntable, an electronic circuit 66 (FIG. 4 ) for controlling the drive assembly, and the control switches 44, 46 for controlling the turntable via thecircuit 66. - In a preferred embodiment, the
interior housing 60 may be formed of moldable plastic to comprise aback wall 68 to which there are attached twovertical side walls top wall 74, and abottom wall 76 to define aninterior space 78. When theinterior housing 60 is positioned within theexterior housing 32, theinterior space 78 of the interior housing is sealed by the interiorfront wall 40 of theexternal housing 32. - Referring to
FIGS. 4-6 , theturntable 38 includes acircular base 80 and acylindrical sidewall 82, giving it a drum-like shape with aninterior bore 84 open at one end. A toothedlarge gear wheel 86 having a diameter approximately the same as thebase 80 is attached directly to the base. Theturntable 38 is rotatably attached to theinterior housing 60 through thelarge gear wheel 86 which is connected to a bearing 88 (FIG. 3 ) mounted on theback wall 68 of the interior housing. - The
drive assembly 64 comprises a smallelectric motor 90 which transmits rotational movement to theturntable 38 via apulley 92 andintermediate gears large gear 86 on the turntable. The use of multiple gears allows for more accurate control of the rotation speed of the turntable than with a single gear. Power for the motor is supplied either by closed cell battery, or by a power cord. Where a power cord is used, with an AC/DC adapter, it plugs into a conventional 110 volt or 220 volt AC outlet. It is preferable to use a motor selected for low power use, while still having the capability to keep proper motion for a watch up to 350 grams, which is about the heaviest watch currently obtainable. - In a further aspect of the invention, best exemplified in
FIGS. 4-6 , theinterior housing 60 may include a plurality of cantilever supports 102 extending from theback wall 68 into theinterior space 78, arranged in relation to each other in a generally triangular pattern. Eachsupport 102 includes a rotatableannular bearing 104 at a terminal end portion of the support, preferably made of rubber or a similar resilient compound. Eachsupport 102 is positioned to permit each bearing 104 to abut the outer surface of thecylindrical wall 82 of theturntable 38 and provide a diametrically inward force to stabilize the turntable against lateral movement, particularly when the turntable is being powered by the motor. Eachannular bearing 104 is preferably positioned to protrude laterally beyond the axial shadow of its associatedcantilever support 102, to prevent any interference betweenturntable 38 andcantilever support 102, allowing the turntable to butt only against thebearings 104. This particular configuration of cantilever supports with resilient bearings provides for smooth, quiet rotation of the turntable. - When the
watch winder 30 is in use, a self-windingwatch 41 is mounted on a cylindrically shaped cuff 39 (FIG. 1B ) which is then inserted into thebore 84 of theturntable 38 so as to allow the face of the watch to protrude on the outside of thefront wall 40 of thehousing 32, and to allow the watch to be rotated by the turntable in the plane of the hands of the watch. Control of the turntable's rotation is achieved by the electronic circuit 66 (FIG. 4 ), which may include a conventional programmable microprocessor capable of receiving input signals, and of generating output signals to achieve control of the turntable. As described in further detail herein, the microprocessor may be configured to activate themotor 90, to determine in which direction the motor will rotate, to count and to limit the number of rotations executed by theturntable 38, to interrupt rotation of the turntable for interspersed periods of time, and/or to terminate rotation of the turntable entirely after a number of rotations until thecircuit 66 is manually reactivated. Operation of thecontrol circuit 66 through the microprocessor is achieved using, for example, switches 44, 46 located on thefront wall 40 of thehousing 32. - In further detail,
control circuit 66 is configured to count the number of revolutions turned by theturntable 38. A light-reflective film 112, formed, for example, as a silver or copper coated plastic film, may be fixed to the outer surface of the turntable'scylindrical wall 82 such that less than 360 degrees, preferably 180 degrees, of the wall circumference is covered by the film 112 (FIG. 6 ). Included in thecircuit 66, an infrared reflective sensor 114 is positioned proximate thecylindrical wall 82 such that, when the turntable rotates through 360 degrees, light emitted from the infrared sensor is reflected from thefilm 112 only throughout the rotational angle wherein the film is present on theouter wall 82, but not where the film is absent. The resulting break in reflected light each revolution is detected by the infrared sensor and is interpreted by thecircuit 66 as marking the passage of a single revolution. Additionally, thecircuit 66 is configured to have a memory which maintains a cumulative count of the number of rotations executed by the turntable. As indicated previously, setting the motor to run for a set period of time may not be sufficient to fully wind the watch, especially where the watch is a large or heavy watch that may cause the speed of rotation to be slowed or where there is a fluctuation in the power supply. Rather, setting thecircuit 66 to allow rotation of the turntable for a set number of rotations before stopping, as contemplated by the present invention, will tend to overcome this problem and have the advantage of terminating the rotations when the watch is likely to be fully wound, thereby avoiding unnecessary waste of battery energy. A suitable infrared reflective sensor for detecting the completion of a rotation by the turntable is a subminiature photointerrupter made and supplied by Sharp, having model number GP2S40. - In a further aspect of the invention, the
circuit 66 may be configured to automatically delay the start of the turntable's rotation, so that, when the circuit is initially activated through theswitches circuit 66 may be configured to provide a short delay in starting rotation, of as little as ten seconds, preferably between 5 and 15 seconds. This has the advantage of allowing the user to activate the circuit through theswitches switch 44. In an alternative embodiment, thecircuit 66 may be configured to allow the user to manually alter the delay time available for each of the various modes of operation. - Preferably, the low battery warning indicator will be functioning even when the
switch 44 is in the “off” position. When theswitch 44 is in the “mode 1” position (short delay) or “mode 2” position (long delay), both the power indicator (green) and the warning indicator (red) will be operational. In a preferred embodiment, the warning indicator also will be flashing when a locked condition of the turntable is detected. - Based on the capability of the circuit to count the number of rotations executed by the turntable, the
circuit 66 may be further configured to pause the motor once a pre-programmed number of rotations has been achieved, and to resume rotation after the pause, continuing with this pattern of rotation and pause until the winder is manually turned off. However, in a further aspect, thecircuit 66 may be configured to automatically terminate the cycles of rotation and pause for a period of time after a predetermined total number of rotations has been executed, preferably, in one embodiment, between 600 and 1200 rotations. The number of rotations will be set to correspond to the average number needed to fully wind most self winding watches. While the number can vary depending upon watch brand, numbers of complications, and the like, in practice, it has been found that about 90° rotations is optimal for most watches - In a preferred embodiment, the circuit may be configured to automatically cause the turntable to be rotated between 100 to 200 rotations, preferably about 150 rotations in a twenty minute period, before pausing for between 30 and 90 minutes, preferably 70 minutes, and then to repeat this cycle several times, preferably six times, before automatically turning off for an extended delay period (preferably about 15 hours). This combination is believed to be optimal in preservation of battery energy. A minimum of at least five rotations per cycle is needed for winding watches with certain unique complication. In a further embodiment, the range of rotations is between 50 and 2500 rotations in each cycle, to accommodate watches with unusual winding systems.
- In a further embodiment, the
circuit 66 may be configured to allow the user to manually adjust the circuit, prior to use of the winder, to variably alter and predetermine the number of rotations in each set of rotations and the length of the pause period between sets of rotations. In yet another feature, thecircuit 66 may be configured to allow the user, prior to use, to cause the direction of each succeeding set of rotations to automatically either reverse direction, or to be all clockwise, or to be all counter-clockwise, to suit the needs of the particular watch as previously described, controlled byswitch 46 which may have a three position setting—clockwise, alternating directions, anti-clockwise. - For example, in one preferred embodiment, the
switch 46 may be set by the user to select between three possible modes of operation. In a first mode of operation, the turntable will rotate clockwise for 150 revolutions, and then stop, representing one rotation cycle. The total time taken for this one rotation cycle will be about 1.5 hours, with about 20 minutes of rotation time and about 70 minutes of pause time. This rotation cycle then repeats six times, and then stops for a long stop period, preferably about 15 hours. The total time taken from the start of rotation to the end of the long stop period is about 24 hours. It has been found that the periods 20 minutes for rotation and 70 minutes for pause enables the winder to wind most watches, while using minimal power. Further, the number of 150 rotations allows the winder to cover the motion requirements for most watches, while using a minimum of battery power. - In a second mode of operation, the operation is similar to that of the first mode, except that the rotation is in the counter-clockwise direction.
- In a third mode of operation, the turntable will start rotating in a clockwise direction for 150 revolutions, then rotate for another 150 revolutions counterclockwise, then stop, representing one rotation cycle. The time taken for this one cycle is about 1.5 hours, with 40 minutes of rotation time (20 minutes clockwise and 20 minutes counterclockwise) and 50 minutes of pause time. This rotation cycle then repeats six times, and then stops for a long stop period of about 15 hours, for a total elapsed time from start of rotation to the end of the long stop period of about 24 hours.
- Any of these three modes of operation can be used in combination with one of the two start-delay modes of operation described above. If either the short delay or long delay is selected, the delay will be disabled after the first 24 hour cycle is completed.
- In another alternative embodiment, the speed of rotation of the turntable and the duration of the pause time, or both, are automatically adjusted and controlled in response to turntable speed to allow for precise time cycle durations, especially where the power source is fluctuating or where a heavy watch is being used.
- With reference to
FIGS. 7-10 , thecuff 39 of the watch winder typically has a generally cylindrical form sized to be inserted into thebore 84 of the turntable. Edges of the cuff may be shaved off to permit a watch to be mounted thereon and still to allow the cuff to be inserted into thecylindrical bore 84. In yet a further aspect of the present invention, thecuff 39 may be configured to be rapidly compressible and decompressible in an axial direction. This feature may facilitate attachment of the watch to the cuff in that the watch strap may be clasped or buckled closed first, whereafter the compressed cuff may be inserted through the closed strap of the watch. After insertion, the cuff is allowed to rapidly decompress under its own elastic qualities to securely hold the watch ready for insertion into the bore of the turntable. In order to achieve rapid compressibility and decompressibility in the axial direction, thecuff 39 of the present invention may be formed of an internal cylindrical block ofopen cell foam 120 having the overall desired shape of the cuff. Thefoam block 120 may be sandwiched between tworigid plates 128, made preferably from rigid hardboard, the resulting combination being enclosed in aporous material cover 122 which is stitched or glued closed at the seams. The combination of open cell foam and porous material gives the cuff the desirable characteristic of being rapidly compressible and decompressible, because both the foam and the fabric will allow air to rapidly escape when the cuff is compressed by hand, and to enter the cuff allowing it to rapidly return to its original shape when the compressing force is removed. Additional features of the cuff may includeflexible pull tabs 124, made of leather or similar material, set in the center of the circular face 125 of the cuff, to allow the user to take hold of and remove the cuff when its edges are inaccessibly located within the bore of the turntable.Rigid push tabs 126 may be set on the circumferential edges of the cuff, to permit the user to take hold of the cuff and introduce it into the bore of the turntable when a watch is located on the cuff, making thepull tabs 124 inaccessible. - Several modifications in the design of the watch winder also are contemplated. In one modification, the operation of the watch winder can be made controllable via a hand-held infrared remote control device, in lieu of or in addition to the
switches - With reference to

FIG. 13 , sub-circuit 213 shows the operation of theinfrared photointerrupter 260 comprising, aphototransmitter 262 and aphotoreceiver 264. As previously set forth, rotation of theturntable 38 past the photointerrupter causes lightreflective film 112 to pass by proximate the photointerrupter. Light emitted fromtransmitter 262 is reflected from thefilm 112 and perceived byreceiver 264 as an energy signal, but when the film is interruptedreceiver 264 registers the break in energy signal and communicates this break toprocessor 200 vialine 280 by switching offtransistor 266. When thefilm 112 returns later in the cycle of the turntable,transistor 266 is switched on again until later interrupted. Each interruption is registered and counted by the program memory in theprocessor 200 for use in controlling the rotation of the motor, as set forth above, through themicroprocessor 200 andsub-circuit 212. A signal from the microprocessor online 282 selectively activatestransistor 268 to control operation of thephototransmitter 262. - With reference to

Additionally, when the battery is below a threshold voltage, the processor sends a signal alongline 300 to switch ontransistor 294 allowing current to flow to ground throughred LED 296.
