Reversible watch, comprising a case ( 1 ) provided with a first face ( 10 ) for displaying first time indications and a second face ( 11 ) opposite said first face. A turning-over mechanism ( 20, 21, 22, 23 ) allows the case ( 1 ) to be turned over around a turning-over axis ( 201 - 211; 221 - 231 ) parallel to the 6 o'clock-12 o'clock axis so as to display at the wearer's preference either the first face or the second face. The turning-over mechanism comprising a pivoting arm ( 20, 21; 22, 23 ) on each side of the case that allows the turning-over axis to be moved back. The case ( 1 ) is connected with the arms ( 20, 21; 22, 23 ) to be able to pivot around the turning-over axis ( 201 - 211; 221 - 231 ). The length of the arms is sufficient for turning over the case without the winding button or other buttons coming into contact with other parts ( 17 ) of the watch.

Description

  The present invention relates to a reversible watch and a method for inverting the case of the reversible watch.

  A reversible wristwatch is a wristwatch with a case having two surfaces and a reversing mechanism that allows the user to display the favorite one of the other surface. At least one side has a dial to indicate the time; on the other side, for example, a dial that displays other times, such as other time zones or complementary functions, and often a decorated protection It has a cover.

  Thus, for example, to display two time zones on both sides of a wristwatch, or to display time on one side and an auxiliary function on the other side, such as chronograph, moon phase, date, etc. Has two mechanical movements for the auxiliary function of displaying. However, incorporating two mechanical movements into the case is expensive and inevitably thick. Wristwatches are also known that can display indications on two opposite faces with only one mechanical movement; such movements are complex, often produced in limited quantities and are equally valued. It is something that stretches. Wristwatches with two quartz movements that are staggered are also known, but they do not have the advantages and luxury of a mechanical movement. Those watches require one battery, especially two batteries.

  Various reversing mechanisms have been considered so far. For example, there is known a wristwatch in which the wristband of the wristwatch and the inner surface and the outer surface of the wristwatch are interchanged by reversing the wristwatch band. However, such a solution requires a reversible band and band clasp that is carefully crafted on both sides.

  Similarly, there is known a wristwatch in which the watch case turns around the center line of the line connecting 9 o'clock and 3 o'clock, that is, the center line perpendicular to the band. In this case, the reversing mechanism normally occupies the space around the watch case part that is assigned to the crown and other operating members that synchronize the time, which imposes aesthetic constraints on the watch manufacturer and designer. It is.

  Therefore, the most popular reversible wristwatch uses a reversing mechanism that can turn the watch case around the line connecting the 6 o'clock and 12 o'clock on the plane of the wristwatch as the center line. For example, in the wristwatch described in the specification of French Patent No. 2716353, each end member of the band is a pivot that can invert the wristwatch with a line connecting the wristwatch at 6 o'clock and 12 o'clock as a center line. Is connected to the watch case. However, in order to turn the watch case, the watch must be removed from the wrist. Similar solutions that can be swung with the band attached are described in particular in British Patent No. 2213612, British Patent No. 2241868, European Patent No. 346660, Swiss Patent No. 659167. , French Patent Invention No. 2583897, Swiss Patent No. 172421, Swiss Patent No. 138929, US Pat. No. 4,470,708 and Swiss Patent No. 672291. .

  Various known solutions further propose to insert the watch case into the outer frame connected to the band and to pivot the watch case in the frame around the pivot around the line connecting 6 o'clock and 12 o'clock To do. Examples of such watches are described in particular in Swiss Patent No. 159446, Swiss Patent No. 176988 and European Patent No. 562522.

  However, in such a solution, the watch case is connected to the outer frame by a single pivot that allows relative displacement of the case with two degrees of freedom. Therefore, such pivots must be machined very precisely, which increases the cost of the mechanism. The flip of the watch is that the watch case is displaced with respect to the frame according to a complex three-dimensional trajectory, which is difficult to grasp, and the user holds one or more glass plates with his finger. Inevitably, finger marks will be left. On the other hand, the reliability of the reversing mechanism is questionable, and the pivot can get caught or broken even with a slight impact or twist. Eventually, members that protrude from the watch case, and more specifically from the watch case such as the operation buttons, may come into contact with the outer frame when turning, which may damage or leave marks on the protruding members. It may end up.

  The pivot attached to the watch case of the reversible watch described in Swiss Patent No. 177310 has a pivot that slides on the groove of the outer frame. The reversal of the watch case is done by turning the case by sliding the pivot over the groove and ending the turn of the watch case until it reaches a vertical position around the pivot. In this case as well, the watch case is connected to the outer frame by only one pivot, which causes a problem in terms of reliability and difficulty in processing.

  Other reversible wristwatches equipped with a reversing mechanism that makes it possible to swivel around the line connecting 6 o'clock and 12 o'clock are two pivots on the outer surface of the watch case led to the groove of the frame A watch case is used which is connected to the outer frame by using. This type of solution is described in particular in Swiss Patent No. 159982 and European Patent No. 22255. In some of these watches, the reliability and robustness of the reversing mechanism has been improved by connecting the watch case and the frame at two points, making the operation necessary for reversing more intuitive. There is no need to touch the glass. However, the centerline displacement that inverts the watch case in these solutions takes place in a plane parallel to the wristwatch and thereby remains deep in the bottom of the outer frame. Therefore, the side surface of the watch case must be configured so that the watch case can be inverted without the surface contacting the bottom of the outer frame. In particular, it is impossible to attach control buttons and crowns that protrude too much to the side of the watch case close to the reversal centerline, and in fact, these organs can come into contact with the bottom of the frame during reversal. Therefore, such a solution is not suitable for a wristwatch having operating members on opposite sides, particularly an operating member that protrudes into the first part around the watch case between 12 o'clock and 6 o'clock, and 6 o'clock and 12 o'clock. It is not suitable for a wristwatch that simultaneously has an operating member that protrudes to the second part around the watch case during the time.

  French Patent No. 766809 specifically describes a reversible watch having a reversing mechanism that can turn a watch case around a line connecting 6 o'clock and 12 o'clock as a center line. The watch case is connected by two connecting rods parallel to each other and is connected to the wristwatch frame. The wristwatch is flipped by lifting the two connecting rods simultaneously and flipping the watch case with respect to the centerline connected to the two connecting rods. The watch case must be reversed by pointing the side of the wristwatch without a winding device in the direction of the frame, but it has operating members on two sides, for example, at 3 o'clock and 9 o'clock at the same time Can not flip the watch case.

Further, the watch case can be turned around the inversion center line even when the connecting rod is lifted only partially. In this case, there is a possibility that the watch case and the winding device may come into contact with the frame 21, which may cause damage or breakage.

No. 4,470,708 Swiss patent No. 6742291 Swiss Patent No. 159446, Swiss patent No. 176988 European Patent No. 562522 Swiss Patent No. 177310 Swiss Patent No. 159982 European Patent No. 22255 French patent invention No. 766809 specification

  In the end, many of the solutions described have developed a major groove in at least some of the stages of reversal, which is detrimental to aesthetics and especially to dust and dirt. There is a risk of exposure, which can inhibit or prevent the watch from turning over. After all, such a groove is a wear part, and if the accuracy of the watch case guide is not very high, it cannot be replaced or even difficult.

  The object of the present invention is therefore to propose a new reversible watch with a reversing mechanism which eliminates the deficiencies of the prior art reversing mechanisms.

  In particular, an object of the present invention is to provide a watch case that is sufficiently rigid and highly reliable and has an operation member that protrudes on one or more surfaces of the watch case, while the operation member and other parts of the watch case are being reversed. It is to propose a reversing mechanism that can be reversed without being damaged.

  Another object of the present invention is to propose a reversing mechanism with fewer moving parts in order to reduce manufacturing costs, reduce dimensions and increase reliability.

  Another object of the present invention is to provide a reversible watch that can provide more functions and displays on both sides of the watch than prior art reversible watches.

  The invention is achieved with the reversible watch and the method by means of the features of the corresponding type of independent claim and the preferred variants shown in the dependent claims.

  In particular, these objects are achieved by a first time display surface for displaying a first time on a watch case, a second time display surface facing the first time display surface, and 12:00 and 6:00. The first part of the peripheral part of the watch case between and at least one operating member of one or more movements of the protruding watch, and the peripheral part of the watch case between 6 and 12 o'clock A reversible wristwatch having, as a first part, at least one operation member of one or a plurality of movements of a protruding wristwatch and a reversing mechanism for reversing the watch case around a reversal centerline, the reversal centerline Is parallel to the center line of the line between 6 o'clock and 12 o'clock when reversed, so that the wristwatch user can choose either the first time display surface or the second time display To display the surface It has become possible way. According to the present invention, the watch case is coupled to the plurality of pivot arms so that the watch case can pivot on the reverse center line coupled to the outer frame. The arms are designed to be able to displace the reversal center line while reversing, and the length and arrangement of the arms prevents the operating member from touching the rest of the watch when reversing the watch case. It is configured as follows.

  Achieving these objects is not limited to this, and includes a first time display surface that displays the first time on the watch case, and a second time display surface that faces the first time display surface. Or it is a reversible wristwatch having at least one operation member of a plurality of movements. The reversing mechanism allows the watch case to be reversed around the reversal center line, the reversal center line being parallel to the center line connecting between 6 o'clock and 12 o'clock when reversing, The user of the wristwatch can display the first time display surface or the second time display surface as desired. According to the present invention, the reversing mechanism includes one turning arm on each side of the watch case. The arm can displace the inversion center line. The watch case is connected to the arm so that the watch case can turn around the inversion center line only when the arm is inclined at a predetermined angle with respect to the initial position. The length of the arm is sufficient, and the arrangement of the arms is such that the operation member and other parts of the watch case do not collide with other parts of the watch when the watch case is reversed.

  This solution has the advantage that the reversal centerline of the watch case can be displaced during reversal. Therefore, when flipping a watch case with a large dimension or having an operation member protruding on one or more surfaces, it is more convenient to prevent the watch case or operation member from coming into contact with other parts of the watch. It is possible to lead to.

  The invention will be further understood from the description of embodiments shown in the accompanying drawings:

  FIG. 2 is a perspective view of a reversible watch according to a first variant of the invention, in which a display board with hands on the surface is visible in a folded state.

  FIGS. 11 to 14 are perspective views of the reversible wristwatch according to the first modification of the present invention from various directions indicating positions during reversal, and in particular, what kind of slider mechanism is used in the first modification. It shows whether or not.

  15 to 18 are perspective views showing various positions during reversal of the reversible wristwatch according to the second modification of the present invention.

  FIG. 19 is a cross-sectional view of the case of the reversible watch according to the present invention.

  FIG. 1 shows the top surface of a reversible watch according to a first embodiment of the present invention. In this position, as also shown in FIG. 2, the time display surface 10 of the wristwatch having the hand display 100 can be seen from above the wristwatch, particularly as seen in FIG. Another time display surface 11 with a digital display is directed in the direction of the wrist of the wristwatch user along with the numerical display 110. For simplicity, the indicator (needle or liquid crystal display) and band are shown only in the rest position shown in FIGS.

  The watch case 1 of the watch has a watch movement, and is attached to the frame 17 by a reversing mechanism 2 described later. The band 13 is fixed to the frame 17 via a protrusion 171. The movement for controlling the position of the hands can be wound up or the time can be adjusted by using the winding device 16 on one of the side surfaces of the watch case 1. The other operation members, in this case, the push buttons 14 and 15, can operate other functions of the wristwatch, particularly functions displayed on the other surface of the wristwatch described later. Since the operation members 14, 15, and 16 are distributed on the opposite side surfaces of the watch case, they are sandwiched between 6 o'clock and 12 o'clock in the same manner as the portion between 12 o'clock and 6 o'clock around the watch case. It occupies the part. The operation member protrudes, and this protrusion makes it easier to operate on both sides of the watch case 1.

  The swivel arms 20 and 21 of the reversing mechanism of the first embodiment are configured to close both front surfaces facing the frame 17 in a folded state. In the illustrated variant, the watch case is rectangular or square and the length of the arm is approximately equal to the width of the watch case. The arms are deployed by pivoting in two vertical planes around the rotation centerline 200 connected to the frame 17 (ie, perpendicular to the bottom 170 of the frame 17), as illustrated in FIGS. be able to. The angle of rotation reached by the arm 20 from the initial position is indicated by the symbol α. The two rotation center lines 200 and 210 of the two arms 20 and 21 are connected in parallel to each other at positions facing each other in the diameter direction of the frame 17.

  The watch case 1 is connected to two swivel arms 20 and 21 by two pivots 201 and 211 that define one inversion center line. Therefore, the watch case can be reversed around the reversal center line 201-211 when the arm is deployed. In the rest position, in order to display either the time display surface 10 or 11, the arms 20 and 21 are bearing steel balls (not shown) attached to springs engaged with the holes 28 on the inner surface of the protrusion 171. Not). To remove the bearing ball and release the arm to unfold and reverse the watch case, a simple vertical force on the watch case 1 is required.

  As seen in FIGS. 3-10, the arms 20 and 21 lift the inverted centerline of the watch case 1 above the original surface with the top surface of the watch case in the rest position, so that the pivots 201-211 are identical. It can be on the line. Therefore, in this embodiment, the reversal center line 201-211 is displaced by turning the arms 20 and 21 around the rotation center line 200-210 during reversal. Therefore, the operation required to lift the watch case 1 is intuitive and does not require complicated movement. The arm 20-21 connects the watch case 1 and the frame 17 in conjunction with each other through all the stages of reversal.

  The lengths of the two arms 20 and 21 and the distance between the rotation center line 200-210 of the arm and the reversal center line 201-211 of the watch case are the operation members 14, 15, 16 and other parts of the watch case 1. Is sufficient for the watch case to flip without contact with the frame 17 or other parts of the watch. Therefore, the time display surface 10 or 11 can be changed when the arm is deployed without fear of scratching, damaging or even damaging the operation members 14, 15, 16 and the watch case 1. In particular, as shown in FIGS. 3 to 9, the two arms 20, 21 maintain a state parallel to the facing direction during reversal.

  In particular, each of the two arms 20, 21 has an A shape, as can be seen in FIGS. 11c and 11d, which show cross-sectional views along the arm centerline Xld, as seen from the inside front of the arm 21, respectively. There are first sliders 202 (not shown) and 212, and pivots 201 (not shown) and 211, respectively. Each of the pivots 201 and 211 displaces the second sliders 250 and 260 processed into S-shapes in the slider holders 25 and 26 respectively connected to the two front faces of the watch case 1. On the contrary, two pivots 251 (not shown) and 261 on which the slider holders 25 and 26 are mounted respectively displace the first sliders 202 and 212.

  The watch case 1 is connected to the outer frame 17 by two arms 20 and 21 guided in opposite directions, vertically displaced and blocked in a horizontal position, and lifts the two arms 20 and 21. While lifting the watch case 1, the pivot 211 is displaced to the S-shaped slider 260 connected to the watch case, and at the same time, the two pivots 261 are displaced to the A-shaped slider 212. Similarly, the pivot 251 displaces the slider 202 of the arm 20, while the pivot 201 displaces the slider 250 connected to the slider holder 25.

  Since the shape of the guide sliders 202 and 212, particularly the A shape, and the two pivots 201 and 211 are not collinear, the watch case 1 is kept horizontal, that is, the inversion shown in FIGS. Any position except the point can be kept parallel to the initial rest position. In fact, each of the two pivots 201 and 211 is on the same line at the center of reversal, and cannot turn at the same time unless it is at the 6 o'clock and 12 o'clock positions. In particular, in this position, such two pairs of guide pivots 251 and 261 are in the circular portion of the respective slider 202, 212. In that case, the slider holder 26 can pivot about the pivot 211, and the two guide pivots 261 rotate equally equally within the circular portion of the first slider 212. The slider holder 25 performs the same reversing motion around the pivot 201.

  That is why the watch case 1 can rotate freely around the horizontal inversion center lines 201 and 211 only at this position. In any other position of the arms 20, 21, the pivots 201, 211 are not aligned, and the paired pivots 251, 261 are guided into the respective sliders, thereby blocking the inversion. The Therefore, there is no possible friction between the front surface of the watch case 1 and the inner surfaces of the arms 20 and 21.

  In the illustrated embodiment, the reversal point is reached when the inclination angle α of the arms 20, 21 is approximately equal to 50 °, and this value is shown in FIGS. 4-8 and 13-14. In order to ensure reversal without collision at the position, it is selected according to the length of the arm and the full width of the watch case. In this way, it is ensured that no point on the watch case 1 or the operating members 14, 15, 16 is involved in contact with the frame 17 when the arms 20, 21 are unfolded or folded.

  The two pivots 201 and 211 define an inversion center line around which the watch case 1 is inverted. When these pivots displace the S-shaped second sliders 250 and 260, the inversion center line defined by the straight line connecting the two pivots 201 and 211 is various when the arms 20 and 21 are deployed. The watch case 1 is crossed from the center along the various directions.

  The non-rectangular S-shape of the second sliders 250, 260 allows control of the friction force applied to the pivots 201, 211. In particular, this shape makes it possible to change the reaction force applied by the friction with the slider when the arms 20 and 21 are expanded and folded, so that the expansion effect and then the elasticity Folding effect can be obtained more intuitively. The reversing mechanism is also less comfortable, but can also operate with the second linear sliders 250, 260.

  In a modification not shown, the positions of the watch case, the arm slider, and the pivot can be reversed. Also, the “legs” of the A-shaped sliders 202, 212 can be expanded inward so as to ensure contact at only one point of the pivots 251, 261, thereby reducing friction.

  To invert the watch case and display another side of the watch, the watch user lifts the watch case 1 to disengage the spring-loaded bearing ball in the hole 28 and then arms 20-21. Is rotated 50 ° (in this example) to reach the inversion position shown in FIGS. 4-8 and 13-14. In this position, the watch case 1 is guided to the guide pivots 251 and 261 between two opposite horizontal positions shown in FIGS. 4 and 7, and freely swivels around the inversion center line 201-212. be able to. Next, the wristwatch user pushes the watch case 1 again to fold the arms 20 and 21 to reach the second rest position shown in FIG. 10 so that the second time display surface 11 can be seen. Like that. The watch case 1 is maintained in that position by a bearing steel ball meshing with another hole 28 on the inner surface of the protrusion 171 on a spring (not shown).

  Sliders 250 and 260 connected to the watch case 1 are wear parts. Therefore, in a preferred variant, the slider holders 25, 26 can be replaced without changing the entire watch case. Therefore, the slider holder is preferably attached to the front of the watch case 1 or screwed by screws engaged in the holes 24; the slider holders 25, 26 are also for inspection and battery replacement It is also possible to hide a screw (not shown) that can open the watch case 1.

  It should be confirmed that the described device can easily flip the watch case 1 without removing the band 13. It should also be noted that the majority of the various sliders are secured by the arms 20, 21, slider holders 25, 26 and the watch case 1 so that the risk of clogging is greatly reduced at any position, especially in the rest position. It is shielded.

  The reversible wristwatch according to the invention preferably has two individual movements 12, 19 which are accommodated in the watch case 1 facing each other (FIG. 19). The first movement 12 displays the time and, in some cases, other additional functions, such as a stop watch or the like, by hand or automatic winding that displays with the hands 100 of the first time display surface 10 of the watch. This is a mechanical movement. The second movement 19 is an electronic movement, such as a quartz movement, for displaying other displays such as a second time and date on the liquid crystal display 110 of the second time display surface 11. As such, this reversible watch combines the advantages of a hand display with the advantages of a digital display, as well as the advantages of a mechanical movement (luxury, battery-less operation) and the advantages of a quartz movement. .

  A second embodiment of the present invention is shown in FIGS. The advantage of the second embodiment is that the timepiece case 1 does not require a slider, so that a thinner timepiece case can be used. Further, the slider is a fragile member, and if it becomes clogged with, for example, a mechanical impact or dust or dirt, it is likely to be unable to move. However, the drawback of this embodiment is that the possibility of contact between the watch case or the operating member and the frame cannot be completely eliminated, as will be described later.

  The reversible wristwatch according to the second embodiment of the present invention is shown in FIG. 15 in a state where the analog display 100 with hands on the time display surface 10 is folded so as to be seen from above. The wristwatch has a watch case 1 connected so as to be connected to an outer frame 17 by two arms 22 and 23. The arms face each other at approximately 6 o'clock and 12 o'clock and are connected to the frame 17 around the rotation center lines 220 and 230 (FIG. 12). The watch case 1 is suitable for turning on the two arms 22 and 23 located on the inversion center line defined by the two pivots 221 and 231.

  In this modification, as can be seen particularly in FIGS. 16 and 17, the two arms 22 and 23 are always kept parallel to each other. The watch case 1 shown in the figure is square or rectangular. The lengths of the two arms 22 and 23 are shorter than the width of the watch case. However, when the arms are completely unfolded at a right angle at the initial position, the operation members 14, 15, 16 and the watch case The other part is not in contact with the frame 17 and is sufficient for the watch case to be reversed. Therefore, the lengths of the two arms 22 and 23 are the sum of the distance between the rotation center lines 220 and 230 and the reversal center lines 221 and 231 plus the thickness of the operation member added to half the width of the watch case. It must be enough to surpass.

  An inversion centerline defined by a straight line traversing the two pivots 221, 231 crosses the watch case along a fixed direction parallel to 6 o'clock-12 o'clock, but is not equal to this diameter. The watch case 1 is fixed to the arms 22 and 23 by a center line without a slider, and the angle between the reversal center line and the watch case 1 is always constant during reversal. Therefore, the connection between the arms 22, 23 and the watch case is more rigid than that of the first embodiment.

  In the rest position shown in FIG. 15, the arms 22 and 23 are in any rest position in the state where the analog time display face 10 is visible and the digital time display face 11 shown in FIG. 18 is visible. The watch case 1 is housed in a folded state in the hollowed-out portion. Therefore, the reversing mechanism is almost invisible in the folded state.

  To invert the watch case 1 and select the time display surface 10 or 11, the watch user lifts the watch case 1 from the rest position shown in FIG. The two arms 22 and 23 are swung in the vertical plane until the watch case 1 is sufficiently separated from the frame 17 so that the watch case 1 can be rotated without colliding. In that case, the watch case can be easily swiveled around the inversion centerlines 221 and 231 to select either the time display surface 10 or 11 that is visible. The arm is then rotated 180 ° to be folded into another rest position shown in FIG.

  Compared with the first modification, in this second modification, the operation members 14, 15 and 16 are moved when the watch case is reversed too early or too late, that is, the arms 22, 23 follow. If the angle α is significantly different from 90 °, it may possibly be involved in contact with the bottom of the frame 17. In fact, the two pivots 221 and 231 that are always on the same line can be reversed at any time. However, the watch case 1 does not remain horizontal throughout all stages of displacement.
