Definitions
- the present invention relates to a timepiece comprising a striking mechanism. It relates to clocks, chronometers and other clock movements. It relates more particularly to portable watch movements, that is to say which can be put in the pocket or attached to the wrist.
- timepieces which emit an audible signal after a predetermined and adjustable time. These timepieces conventionally include a timepiece movement ensuring in particular the measurement of time and a striking device whose triggering is controlled by the movement. Timepieces of the aforementioned type are designed, for example, to measure a time limit for parking a vehicle, and remind the user using a buzzer or a stamp that the parking time has expired .
- a first category of timepieces relates to clocks, alarm clocks and other wristwatches which are fitted with a striking device actuated by the same spring barrel as that which supplies the mechanical energy to the timepiece device. These mechanisms therefore comprise a single spring which ensures in the first period the operation of the watch movement, and which provides in a second period the energy necessary for the operation of the warning signal.
- Such mechanisms are essentially characterized by the fact that between the moment of arming and setting the time and the moment of triggering the alarm, the barrel drum activates the clockwork movement, while that at the time of triggering, a hammer is released which strikes a stamp of any suitable type, said hammer then being actuated by the same barrel drum, but the spring of the clockwork movement acting, thanks to a special mechanism, by a detent movement in the opposite direction.
- the winding crown which, originally, is intended for winding the only movement which ensures the measurement of time, is also used for winding the ring.
- the present invention therefore aims to remedy the aforementioned drawbacks, as well as others, by providing a timepiece comprising a striking device whose interest lies in particular in the safe operation of such a mechanism , thanks to the use of movements capable of being mass produced and, consequently, of a more advantageous cost price, given the simplicity of the modifications to be made to the basic movement.
- the present invention relates to a timepiece comprising a timepiece movement ensuring in particular the measurement of time, and a striking device actuated by a mainspring barrel independent of the timepiece movement, this timepiece also comprising mechanical control means capable of being actuated manually to engage the striking device, characterized in that the barrel is raised by means of a winding bar terminated at its free end by a toothed sector and kinematically connected to a winding plunger on the one hand, and on the other to the mainspring of said striking device.
- the present invention provides a timepiece provided with an acoustic alarm mechanism based on a conventional timepiece movement, capable of emitting a warning signal at the end of a predetermined period of time.
- the pusher used in the context of the invention is also a conventional pusher, produced in large series and therefore inexpensive, the installation of which does not require modification of the clockwork movement and does not affect the sealing, for example a box in which said clock movement is installed.
- the ringing is actuated by an auxiliary spring barrel independent of the movement ensuring the measurement of time, the construction of the timepiece according to the invention is greatly simplified and therefore less costly.
- the mainspring intended to actuate the striking device is armed by means of a winding bar terminated at its end by a toothed sector and kinematically connected to the winding plunger on the one hand, and on the other to the mainspring of the striking device.
- FIG. 1 is a plan view of a timepiece containing the striking mechanism according to the present invention
- FIG. 2 is a plan view of the striking mechanism arranged between a winding plunger and a striking train;
- FIG. 3 is a plan view on a larger scale of the striking device shown in Figure 2, not yet triggered;
- - Figure 4 is a view similar to that of Figure 3 on which the ringing device according to the invention has been triggered;
- FIG. 5 is a front view of a barrel-forming part inside which is wound the mainspring whose outer coil is attached to the barrel, and whose inner coil is fixed to a barrel shaft;
- FIG. 6 is a plan view of a wolf tooth wheel which constitutes the first wheel of a regulation chain, and
- FIG. 7 is a front view of the entire warning mechanism.
- the present invention proceeds from the general inventive idea which consists in using for the winding of a mainspring whose force is used only for the actuation of a warning mechanism a single push button.
- This pusher is of the type commonly available commercially, and can be mounted very easily in a sealed manner, for example on a watch case equipped with said warning mechanism.
- the invention therefore makes it possible to meet market demand for a waterproof winding push button, not detrimental to the aesthetics of the watch and easy to install.
- the present invention will be described with reference to a timepiece of the wristwatch type. It is however understood that the present invention is not limited to such an application and that it can be advantageously used within the framework of any other application requiring counting down a time and marking the end of the countdown by the emission of an audible signal.
- a timepiece of the wristwatch type comprising a striking device in accordance with the present invention is shown in plan view in FIG. 1 and generally designated by the general reference numeral 1.
- This timepiece 1 comprises hands timepiece, namely an hour hand 2, a minute hand 4 and a small second hand 6.
- a calendar with large aperture 8 completes the timepiece mechanism.
- the timepiece 1 taken here as an example further includes a chronograph function with a second hand 10 and a minute counter 12. The starting and then stopping of the hand 10 and of the counter 12 are carried out by means of 'a first pusher 14, while a second pusher 16 allows said indicators 10 and 12 to be reset to zero.
- a crown 18 allows, according to the axial positions to which it is brought, to wind the timepiece, to set the calendar and set the hands 2, 4 and 6 of the timepiece mechanism.
- the minute counter 12 is also used as a timer or countdown time counter, the setting of the period to be counted down being corrected using the crown 18.
- the start of the countdown counter and the winding of a part 20 forming a barrel and actuating a striking device 22 audibly indicating to the wearer of watch 1 the end of the countdown are carried out simultaneously by pressing on a third pusher 24
- the timer 12 comprises a dial 25 having three concentric scales of ten minutes each and each traversed by a needle of different length 26, 28 and 30 of which only one is visible in FIG. 1.
- the timepiece comprises a striking device 22 actuated by the barrel 20 above.
- the barrel 20 is actuated by a toothed sector 32 formed on a bar 34 leading to the control and winding push-button 24.
- the barrel assembly 20 which will be described in detail below carries at least one lug 36 (in the examples shown in the figures, these pins are preferably three in number) which actuates a hammer bell 38 which strikes a stamp 40 of any suitable type.
- This assembly drives the ringing device 22 which here comprises three mobiles, one of which is a terminal mobile 42.
- the striking device 22 can be armed independently of the progress of the clockwork movement (not shown) by pressing the push button 24 which causes the arming of a mainspring 44 whose full force is used solely for actuating the striking device 22.
- the mainspring 44 is armed by means of the winding bar 32 terminated at its free end by a toothed sector 32, preferably a rack.
- the winding bar 34 is kinematically connected to the winding plunger 24 on the one hand, and on the other to the mainspring 44 of the striking device 22.
- the striking device 22 can be placed anywhere in the case 46 of the timepiece 1, for example to take account of the requirements linked to the size of the movement d watchmaking or for aesthetic reasons.
- winding plunger 24 is of the type commonly used in the field of the watch industry. It is therefore available in large series and at a more advantageous price. On the other hand, its mounting on watch box 46 turns out to be remarkably easy and does not in any way affect the tightness of said watch 1.
- the mainspring 44 is wound inside the barrel 20, hooked by its outer coil 48 to said barrel 20, and to a barrel shaft 50 by its inner coil 52.
- the barrel 20 is freely rotated around its shaft 50 when it is mounted on a plate of the movement, so as to impart to the mainspring 44 an appropriate initial tension, then is immobilized definitively on the plate after assembly by means of a retaining member 54 such as, for example, a pawl.
- the spring is therefore claimed during assembly of the striking device 22, so that the stroke of the pusher 24 which is typically of the order of a millimeter is sufficient to arm said spring 44.
- a rack pinion 56 is provided.
- This pinion 56 forms the drive member of the striking device 22.
- the winding bar 34 extends in a direction parallel to the movement of the pusher 24 and is preferably aligned with the longitudinal direction of the latter.
- the bar 34 is associated with means for guiding in translation. These guide means comprise, in the example illustrated, two pins 38 which penetrate into respective oblong holes 60 made in said bar 34. Rotated by the rack 32, the pinion 56 rotates, transmitting its rotational movement to the shaft of barrel 50.
- the mainspring 44 As the mainspring 44 is mounted fixed by its two ends 48 and 52 respectively to the barrel 20 and to the barrel shaft 50, it stretches and stores energy which it will later restore to the striking device 22 when it takes place.
- a triggering mechanism 62 which will be described in more detail later is arranged between the striking device 22 and the clockwork movement to make it possible to prevent said striking device 22 from operating before the end of the countdown. .
- the mainspring 44 can only be unwound after the terminal mobile 42 of the ring 22 has been released by the above-mentioned trigger mechanism 62.
- a driving wheel 64 is mechanically coupled to the barrel shaft 50.
- this wheel 64 actuates the striking hammer 38 which then strikes the stamp 40, which causes the emission of one or more of several successive sound signals.
- the drive wheel 64 has a multiplicity of lugs 36 (three in number in the figures) which, when the motor spring 44 is unwound, cooperate with a tilting mechanism 66 causing the hammer 38 to recede against the return force of a spring 68 and, consequently, the abrupt movement of said hammer 38 forwards against the stamp 40.
- the tilting mechanism 66 mentioned above comprises a pawl 70 pivotally mounted on the lever 72 of the hammer 38.
- This pawl 70 has the particularity of being able to slide on the lug (s) 36 of the driving wheel 64 when the latter turns in the clockwise during winding of the mainspring 44.
- the mainspring 64 when the mainspring 64 is armed, the pawl 70 has no action on the hammer 38, that is to say that it does not 'not cause the latter to tip over.
- the mainspring 44 disarms, the driving wheel 64 turns anti-clockwise and causes the pawl 70 to pivot by its lugs 36.
- the pawl 70 which then abuts against a pin 74 secured of the striking hammer 38, communicates to the latter its tilting movement.
- the pawl 70 must have two teeth 76 and 78 angularly spaced and rigidly connected to each other.
- the first tooth 76 cooperates with the lugs 36 of the drive wheel 64, while the second tooth 78 presses on the pin 74 during disarming of the mainspring 44 and communicates to the striking hammer 38 its tilting movement.
- the pins 36 are three in number, regularly spaced around the outer perimeter of the drive wheel 64. This means that the hammer 38 will strike the stamp 40 three times and thus produce three blows successive rings at regularly spaced successive time intervals.
- the lugs 36 could not be regularly spaced, two of these lugs 36 can for example be brought closer to each other, while the third would be at a greater distance from the first two. In this case, the wearer of watch 1 would hear two almost simultaneous bell strokes and a third bell stroke further away.
- the pawl 70 is maintained in elastic contact with the drive wheel 64 by means of a retaining spring 80 mounted fixed on the clockwork movement of watch 1.
- the striking hammer 38 had to be tilted by means of the drive wheel 64 provided with its lugs 36 against the elastic return force of a spring 68 Once that of the lugs 36 which is engaged with the pawl 70 has exceeded said pawl 70, the hammer 38 is free to tilt. The spring 68 then relaxes, and suddenly projects said hammer 38 against the stamp 40. It is now necessary to provide a mechanism allowing the hammer 38 to be returned to its rest position.
- the hammer 38 is returned to its rest position by a spring 82.
- the spring 82 is mounted fixed at at least one point on the clockwork movement. More specifically, the spring 82 is fixed to the clockwork movement by a first screw 84 and has a notch 86 in which a second screw 88, also integral with the movement, projects. The notch 86 is intended to make up for any play and to compensate for any misalignment of the spring 82.
- a pin 90 is fixedly mounted on the lever 72 of the striking hammer 38.
- the timepiece according to the invention also comprises a braking mechanism 94 for slowing down the speed of rotation of the driving wheel 64 when the driving spring 44 is unwound.
- This braking mechanism 94 firstly comprises a wolf tooth wheel 96 fixed on a square 98 of the barrel shaft 50 and which cooperates by its external toothing with a pawl 100.
- the spout 102 of the pawl 100 is pushed back by the teeth of the wheel 96 when winding the mainspring 44, that is to say when said wheel 96 rotates anti-clockwise.
- the mainspring 44 relaxes, the spout 102 of the pawl 100 snaps into the teeth of the wolf tooth wheel 96 and rotates a wheel 104 on which it is pivotally mounted.
- the pawl 100 in engagement with the teeth of the wheel 96, drives the wheel 104 in rotation.
- This wheel 104 is the first wheel of a regulation chain 106 by centrifugal force of the unwinding speed of the mainspring 44.
- the pawl 100 is maintained in elastic contact with the wolf tooth wheel 96 by means of a friction spring 108.
- a trigger mechanism 62 is disposed between the striking device 22 and the clockwork movement to prevent said striking device 22 from operating before the countdown ends.
- the mainspring 44 can take place only after the terminal mobile of the ring 22 has been released by the above-mentioned trigger mechanism 62.
- the trigger mechanism 62 comprises a retaining member 110, advantageously a stone, which is received in one of the notches 112 formed on the terminal mobile 42 of the regulating chain 106 and immobilizes it. ci, so that blocking of the ringing device 22 is possible up to a defined triggering time.
- the stone 110 is mounted fixed in a bolt 114 whose retaining force is adjustable by means of an adjustable spring 116.
- the operation of the trigger mechanism is as follows.
- the period of time to be counted down by the countdown time counter before actuation of the bell is adjusted by the wearer of watch 1 using the crown 18 visible in FIG. 1.
- the winding of the spring motor 44 is performed by pressing on the push button 24.
- the countdown timer counts down the time remaining before having to hear the bell to indicate that the countdown has come to an end, or when the clock movement ensures another function such as the measurement of current time or a timing function
- the stone 110 is forced against the terminal mobile 42 of the regulating chain 106 by the spring 116 (see Figures 2 and 3).
- an unlocking finger (not shown) linked to the clockwork movement by means of said time counter actuates a control spring 118 which has the pin 114 of so as to rotate the latter in the direction of the arrow F (see FIG. 4), so that the stone 110 emerges from the notch 112 in which it was housed and releases the terminal mobile 42 from the regulating chain 106 , thus allowing the mainspring 44 to take place so that the striking device 32 can chime.
- winding bar 34 is free to move rectilinearly between a rest position in which the control and winding push-button 24 has not yet been actuated, and a limit position in which the push-button 24 has been pressed in and which corresponds to the armed state of the mainspring 44.
- the winding bar 34 will then gradually return from its end of travel position to its rest position as and when, aided by a spring recall 120.
