Definitions
- the present invention relates to a movement for a wristwatch and a wristwatch.
- the gears do not allow to easily transmit forces to an opposite point of the movement, or from the lower surface to the upper surface of the movement.
- the belts or connecting rods offer additional possibilities, but occupy a large volume. On the other hand, it is difficult to transmit large forces or torques with small mechanical members.
- the present invention therefore aims to solve these problems with a watch, or at least a watch movement, provided with a hydraulic system.
- the hydraulic system can be used for example to transmit forces or couples from one point of the movement or the watch to another. It can be used for example to replace all or part of the gear train, for animations on the dial or for complications. It is also possible to use a hydraulic system entirely or partially out of the box, associated for example with pushbuttons, the winding crown, a cover, a bottom or the bracelet.
- the hydraulic system can also be used to lubricate the watch movement, bringing the oil where it is needed. Instead of removing the oil from the movement, we add some.
- hydraulic system in the present application a system employing a liquid fluid, for example lubricating oil.
- the fluid is preferably circulated, at least at times, to transmit a force or lubricate the movement or other organs.
- Displacements can also be constituted by variations in the pressure applied to the fluid, for example by compressing or releasing it.
- the hydraulic system therefore uses a fluid that passes through pipes, and / or cylinders, and / or pistons, etc. integrally linked to the movement or the watch case.
- the hydraulic system is preferably fully closed, to avoid unwanted liquid losses when the watch is shaken or returned.
- the system must be adapted to a wristwatch.
- the wristwatch is preferably regulated by means of a conventional regulating member, for example a spiral balance assembly or a quartz oscillator; the hydraulic system intervenes so only to lubricate this regulator (or other organs) and / or to transmit forces in the movement and in the watch.
- the accuracy of the watch is virtually independent of any dilation or deterioration of the liquid.
- Figure 1 illustrates in block diagram form an example of a hydraulic system according to the invention.
- FIG. 1 schematically shows a hydraulic system 1 for a watch or watch movement. All the components of this scheme are optional and not essential to the invention.
- the system is preferably housed at least partly within a watch case, and integrally linked to the movement of the watch.
- the watch further comprises a display mechanism for displaying time data of the movement, for example needles or a not shown window display.
- the system comprises a housing 2 to recover the oil coming out of the hydraulic system.
- the housing can be constituted by a bridge or a plate, see by the bottom of the watch. It is possible to use an open sump that recovers oil only when the watch is worn in a normal position with the dial facing up. However, it is important to ensure that the oil does not enter the dial or other exposed areas.
- An oil or liquid reservoir 4 preferably inside the watch case contains the reserve of fluid necessary for the operation and / or lubrication of the movement.
- the tank can preferably be filled, for example without opening the watch or without disassembling the movement, by introducing oil through an opening closed by a plug 5, for example a cap accessible from outside the watch case.
- the level of oil or liquid can be displayed by an oil gauge, for example a gauge having a rotating or linear needle visible from outside the watch, for example on the dial or near the bottom. An insufficient oil level can also be indicated with the hands of the watch or with another indicator of the watch.
- a simple deposit of oil on a bearing, an axis or in a cylinder or piston for example is not considered a reservoir; a tank means a container for storing a liquid used elsewhere.
- the fluid circulates in the hydraulic system through pipes 6, for example flexible pipes made of metal or synthetic material or rigid pipes, for example in a metal such as steel, stainless steel, copper, copper or aluminum. brass or gold. Rigid pipes made of ceramic or plastic are also possible.
- the pipes can be in motion, around the movement, through the box or even through the box or dial.
- certain pipes may be visible through the ice of the wristwatch; for example transparent pipes will be used to see the movements of the liquid, which can also be colored.
- the pipes, or other components of the hydraulic system can also be made by micro-fluidic technologies, that is to say by machining cavities, valves, etc.. in a substrate of silicon or synthetic material with lithographic techniques or ion beams for example.
- An expansion tank 8 automatically regulates the pressure in the hydraulic system.
- the expansion vessel comprises for example a membrane which is deformed according to the difference between the atmospheric pressure and the pressure of the liquid.
- the viscosity of the oil and many liquids varies depending on the temperature. This effect may be desirable because it allows for example to increase the force transfer rate by heating the oil. In other cases, this effect is undesirable.
- the change in temperature of the liquid can cause significant expansion, especially in a small diameter pipe.
- the hydraulic system may comprise one or more heat exchangers 10, 12.
- a first heat exchanger 10 near the upper surface of the movement or near The edge of the box allows the liquid to cool by circulating it near the ambient air.
- a second heat exchanger 12 near the bottom of the watch on the contrary allows to warm the liquid with the body temperature of the wearer of the watch.
- Valves 14 may be opened in all or nothing or in a controlled manner to circulate the fluid through one or the other of the heat exchangers, or directly.
- the valves can be manually controlled by the user of the watch, using the watch movement, depending on the dilatations of the liquid, or depending on the temperature for example.
- the temperature of the fluid can also be controlled by changing its pressure, for example by compressing or releasing it.
- a pump 24 can circulate the liquid in the hydraulic system.
- the pump 24 is advantageously actuated by the movement of the watch, for example using the energy accumulated in the barrel.
- the liquid can circulate continuously when the watch is running, or only when certain movements have to be made. Displacements of liquid fluid can thus be actuated by the mechanical elements of the movement. It is also possible to use the wearer of the watch to actuate the liquid.
- the liquid is displaced when the user compresses it with a particular motion, and then when the released liquid is decompressed.
- the liquid or the oil of the hydraulic system can be used to lubricate gears 20, bearings, stones or other organs of the mechanical movement, continuously, on demand or automatically but discontinuously.
- the hydraulic system 1 may include one or more nozzles or other means for spraying the lubricant at the appropriate locations.
- the liquid or oil of the hydraulic system can also be used to actuate one or more actuators 22 rotating or linear, for example a cylinder, a piston, a turbine, a valve, etc.. These actuators may be inside the watch case or at least partly outside.
- a hydraulic actuator will be used to drive organs that must move rapidly, for example a date or day disk, month, etc. or a retrograde hand, or other display elements making sudden movements, including chronograph hands.
- the hydraulic system can also be used to store energy, for example by compressing the fluid in a piston or cylinder. It is for example possible to store the energy for 24 hours in a jack released suddenly at midnight to rotate the date disc.
- One or more pipes make it possible to dispose the cylinder or the piston storing the energy at a location of movement away from the one where the energy is used or produced.
- the hydraulic system can also be used to rotate the cage of a tourbillon along one or more axes, or for other horological complications. In the case of a watch movement equipped with several regulating members, the hydraulic system also makes it possible to switch very quickly the regulating member used.
- the hydraulic system can also be linked to pushbuttons or to the crown of the movement, for example to transmit axial or rotary movements in remote locations of the button or the crown. For example, it is possible to replace the crown rod or a push button with a pipe, including a non-straight pipe, containing a liquid pressurized by the actuation of the button to transmit commands from outside the the box towards the movement.
- the hydraulic system can also be used to transmit forces from the inside of the movement, or from a push button, to a body of the box or external to the box. It is for example possible to order cylinders or other actuators in the box, or linked to the box, for example to open a cover, move the bezel, unhook the strap fasteners to the box, open the bottom, etc. from an action triggered for example since the movement or from one of the pushers or crowns. It is also possible to automatically deploy push buttons for example when the watch enters chronograph mode, or move a bevel gear to mesh the winding crown in different axial positions.
- the liquid can also flow between two windows, for example between the outer ice and an inner ice, or between the dial and an ice, to transmit movements invisibly.
- the movement of the invention may also comprise perforated flanges displaced relative to one another to allow the passage of liquid when two holes on two flanges are opposite, or block this passage when the holes no longer match.
