Definitions

  • the invention relates to a watch provided with at least one electronically manageable function and provided with a control member for controlling said function.
  • Mechanical or electromechanical watches include as standard a stem-crown which makes it possible to adjust the position of the hands by turning the crown, as well as to wind the barrel in the case of a mechanical watch.
  • the crown In most cases, the crown is in a resting position close to the watch case and needs to be pulled out to a setting position to adjust the time and, if applicable, the date.
  • More and more additional functions are provided, such as an electronic display of personal and/or geographical information, for example a diary, fitness and geolocation data. This is also the case for watches equipped with a mechanical movement, for example by adding an electronic module comprising a digital screen arranged on part of the dial.
  • the invention aims to provide a watch which does not suffer from the drawbacks described above. This object is achieved by the watch according to the appended claims.
  • a watch according to the invention comprises a control member which controls one or more electronic functionalities.
  • the control member is elastically mounted on an elongated element, so that the user can swing the member in at least one direction and preferably in two dimensions with respect to the elongated element.
  • At least one proximity detector is incorporated in the middle part of the watch, at a location which enables this detector to produce a signal which is representative of the rocking of the organ around an axis which is perpendicular to the central axis of the elongated element.
  • a processor generates at least one command on the basis of signals supplied by the proximity detector or the proximity detectors, for example to allow the user to navigate in a menu or a calendar displayed on a digital screen of the watch.
  • the invention applies just as well to watches provided with a mechanical movement as with an electromechanical movement. It can even apply to an electronic watch without hands.
  • the watch is provided with additional functions with an electronic character.
  • This watch may include a digital screen which extends over a portion of the dial, provided for displaying the time by hands, and on which various data are displayed, such as the date, the time, alphanumeric messages or other information which is accessible for example by navigating in one or more menus.
  • the watch comprises a stem-crown mechanism for winding and adjusting the hands, which is well known in the state of the art.
  • the crown also serves as a means of controlling electronic functions, thanks to a set of sensors forming proximity detectors which are used to detect a tilting of the crown along two dimensions orthogonal to the axial direction of the rod.
  • the figures 1 and 2 represent vertical and horizontal sections of the stem-crown mechanism in a watch according to one embodiment of the invention.
  • crown 1 is connected to a winding stem 2 by means of a stem connector 6 driven onto one end of stem 2.
  • the assembly of stem 2 and stem connector 6 passes through through a tube 3 fixedly mounted in a hole 4 provided in the wall of the middle part 5 of the watch.
  • middle 5 forms the support in which is installed a watch movement which is adjustable by the stem-crown mechanism.
  • O-rings 9 are inserted between the tube 3 and the middle part 5 and between the tube and the rod connector 6 to ensure the tightness of the mechanism.
  • the crown is mounted on one side of the rod connector 6, so that the rotation of the crown around its central axis 10 drives the rod connector 6 and the rod 2 in rotation, around their central axis 10 'which is coaxial with the central axis 10.
  • the coupling rod 6 is housed in the tube 3 in a rotatable manner, and with a reduced tolerance, so that the coupling rod 6 is essentially immobile in the radial direction.
  • the assembly of the fitting-rod 6 and of the rod 2 represents an embodiment of an elongated element to which the crown is fixed.
  • this set can take different forms depending on the type of watch.
  • the rod connector and the rod can form one and the same element.
  • the elongated element is an element which defines a central axis 10' and which protrudes from the caseband 5 of the watch, the outer end of this elongated element forming a ball joint for the crown, as will be explained in more detail later.
  • the crown 1 is only one embodiment of a control member mounted laterally with respect to the caseband and to which the invention is applicable.
  • a control member is the (generally non-rotating) head of a pusher fitted to a chronograph. The invention will be described for the case of the rotating crown, which represents the most common case in the horological field but which does not limit the scope of the invention.
  • control member which have a designated function linked to the rotation or the axial movement of the control member.
  • the invention also covers a control member which is neither rotatable around the axis of the elongated element nor movable in the axial direction.
  • the control member is firstly dedicated to the 'joystick' function according to the invention.
  • the crown 1 is shown in a position relatively close to the caseband 5, for example at a distance 'q' (marked on the figure 1 ) less than 1 mm. This position is called the resting position. In a manner known per se, this position allows for example the user of a mechanical watch to wind his watch manually by turning the crown 1. According to embodiments, and in a manner also known, the crown 1 can be moved away of the caseband 5, by manually pulling this crown and driving the stem 2 in the axial direction, to activate mechanical adjustment modes such as adjustment of the position of the hands and, where applicable, the date.
  • Various systems exist which regulate the axial positioning of the crown 1 and the actuation of the mechanical adjustment, and the invention is applicable in combination with any one of these systems. Independently of the system applied, the invention relates to functionalities provided to crown 1 when the latter is preferably in the rest position.
  • the crown 1 is mounted on the connection rod 6 via a cylindrical block 15 of elastic material, forming a ball joint, which makes it possible to cause the crown 1 to swing, in a self-reversing manner, around the axes Y and Z of a system of orthogonal axes XYZ, whose axis X is collinear with the central axis 10' of the rod 2 and the central axis 10 of the crown. More particularly, the Z axis is essentially perpendicular to the general plane of the caseband 5, and Y is in this general plane. The swinging of the crown around the Y and Z axes can be actuated by the user, by manually manipulating the crown 1 with respect to the caseband 5.
  • the user can swing the crown around Y or Z separately or simultaneously (the latter being the case for most two-dimensional manipulations).
  • the self-reversing nature of the rocking means that the crown returns to its rest position as soon as the user releases the crown 1.
  • the material of the ball joint 15 is selected such that this self-reversing rocking is achievable.
  • An elastic or elastomeric material of adequate flexibility can be used for this purpose.
  • two proximity detectors 16 and 17 are integrated in the middle part 5, so that these detectors make it possible to measure the variations in the distance between the middle part 5 and the crown 1, according to the respective rotations of the crown around the axes Y and Z.
  • the detectors 16 and 17 are integrated into the tube 3, and the tube 3 is incorporated into the wall of the middle part.
  • detectors 16 and 17 are positioned orthogonally to each other. A deviation from this orthogonal positioning is permitted, provided that the swings around Y and Z can be derived from the measured signals, taking into account the angular position of the detectors in the YZ plane. Any type of proximity detector can be used. Preferably, and as is the case in the embodiment illustrated in the figures, variable reluctance magnetic detectors are implemented. In the figures 3 to 6 , we see how the detectors 16 and 17 are integrated into the tube 3.
  • Each of the detectors comprises a rod in the shape of a 'U'. This rod is made of a ferromagnetic material, such as ferrite.
  • the rod comprises two legs 20 and a connection portion 21 between the legs 20.
  • the two legs 20 are inserted in respective blind holes 22 provided in the wall of tube 3, in an axial direction of this tube, so that the ends of the legs 20 are positioned close to the outer lateral surface 23 of the tube 3, this surface 23 being in face of the back part of the crown. Holes 22 could also pass through tube 3 from side to side.
  • the connector portion 21 is provided with a solenoid 24 which is connected to a printed circuit board (PCB) 25 attached to the inner side surface of the tube 3, and on which there are means (not shown) for measuring a current passing through the solenoid 24.
  • PCB printed circuit board
  • the detectors 16 and 17 are positioned next to the stem-crown mechanism, but at a distance such that the ends of the legs 20 are opposite the inner surface of the crown 1
  • a ring 26 of ferromagnetic material (for example ferrite) is incorporated in the rear part of the crown 1, so that the side surface of this ring 26 is opposite the ends of the legs 20 of the two detectors whatever the position. angle of the crown.
  • Each of the U-shaped rods forms part of a magnetic circuit with variable reluctance, the reluctance being variable as a function of the axial position of the ring 26 of the crown 1.
  • a change in the distance between the ring 26 and the detectors, obtained by tilting the crown thanks to the elastic ball joint, will change the reluctance of at least one of the two magnetic circuits, which will be detected on the basis of a change in the current flowing in at least one of the solenoids 24 when a given voltage is applied to each of these solenoids (also called coils).
  • a processor (not shown) is on board the PCB 25 to process the signals generated by the two proximity detectors and to translate them into commands which will manage one or more electronic functions of the watch, for example the piloting of a slider on the digital watch screen. It is possible to implement methods and algorithms well known in the field of computing, for the processing of signals as well as for the generation of commands.
  • a battery or other source of electrical energy such as a photovoltaic cell, is present in the watch to power the components mounted on the PCB 25 and/or other electronic components implemented in the watch.
  • a watch according to the invention could comprise a single detector arranged so as to be able to measure a manipulation in a single direction, for example only the detector 16. It is also possible to provide more than two detectors, for example four located at four places around of the axis of the crown, corresponding in particular to the angles 0, 90°, 180° and 270°.
  • particular embodiments are, for example, the allocation of specific functionalities according to the direction in which the control member is manipulated in a plane perpendicular to the central axis 10'.
  • the rocking around the Y axis, detected only by the detector 17 could command a different function than the rocking around the Z axis, detected only by the detector 16.
  • the processor is preferably configured so that a slight deviation of the axis of rotation of the swing from the Y and Z axes will be neglected.
  • the crown 1 (or any other control member to which the invention is applicable) is capable of undergoing a self-reversing axial displacement from the rest position, like a chronograph pusher.
  • This axial movement is actuated by the user who pushes the crown briefly towards the caseband 5 and then releases the crown, which automatically returns to its initial position.
  • the watch is provided with a detector arranged to detect this axial displacement so that the processor generates in response a specific command and different from the commands generated by the swinging of the crown.
  • the commands generated by pushing the crown can be commands for confirming a selection from options presented for example in a menu.
  • the reversible push can also be used to activate or deactivate the 'joystick' function of the crown.
  • the duration of the push can determine the command. For example, a longer duration for activating or deactivating the 'joystick' function and a shorter duration for confirming a selection as soon as the function is active.
  • the detectors 16 and 17 themselves are used to detect the reversible thrust of the crown towards the middle.
  • This can be achieved by configuring the processor so that an axial displacement of the crown, causing this crown and therefore the ferromagnetic ring 26 of the two detectors to move closer together, which is therefore detected simultaneously by the two proximity detectors, is interpreted as reversible thrust of the crown.
  • an axial displacement of the crown generates the same variation of distance (the same reduction in the distance 'q') for the two detectors which are arranged to detect this distance variation.
  • an additional detector can be implemented, which is specifically configured to detect the axial displacement of the crown in the direction of the caseband.
  • a pair of galvanic contacts could be provided which touch when the crown is pushed in, or more preferably a capacitive sensor could be implemented.
