Definitions

  • the present invention relates to electronic watches which have a control system placed in the bottom of their case and more precisely to watches of this kind which comprise a bracelet with a closure element.
  • control system here designates all or part of the devices or organs which are made available to the wearer to enable him to set his watch on time and, possibly, to exercise control over additional functions that it is able to perform, such as that of calendar or alarm clock.
  • this definition does not exclude the case where the system is limited to a single device. This can happen when the watch is very simple and intended to indicate only the hours and minutes or because it is able to respond differently depending on whether the device is operated for a very short or relatively long time or more or less than times for a specified time.
  • control devices that are currently known and which can be placed at the bottom of a watch case. They may, for example, be movable or non-movable members which react to a pressure (push-buttons, membranes associated with an internal electrical contact, piezoelectric keys). They can also be devices which operate on a purely electrical principle (capacitive keys, simple and isolated contacts which can be earthed by touching them with your finger or by connecting them to the watch case by means of 'a metal object, pairs of contacts that are connected together).
  • the watch which is described in French patent application No. 2 212 574 for example comprises one or more devices of this kind.
  • the or each device constituted by two contacts placed at the bottom of two respective small cylindrical holes and which must be connected together by a conductive U-shaped piece, foreign to the watch.
  • electromagnetic devices which include a relay housed entirely in the watch which can be actuated from the outside using a small magnet.
  • the object of the invention is to make a control system placed at the bottom of the case of a watch as practical to use as those which are on the side or at the front and which, themselves not more, are not always perfect from this point of view.
  • the invention also aims to eliminate this drawback.
  • an electronic watch according to the invention which comprises at least one control device secured to the bottom of its case, this bottom being provided with positioning means which determine at least approximately the place where means external to the box must be placed to be able to actuate the control device in question, this control device is chosen and placed in the bottom of the box so that at least part of the closure element of the bracelet of this watch can be used as external means to activate it and that the positioning means are adapted to the shape and dimensions of this part of the closure element.
  • control device can be easily operated with something that is always on hand when wearing the watch.
  • the bottom of the box is also provided with means for guiding the part of the closure element which makes it possible to actuate the control device towards the means of positioning.
  • the watches of FIGS. 1 to 3 all include a box 1 which contains the various elements necessary for the production of a watch with analog, digital or mixed display and to which is attached a flexible strap 2 quite classic, with a strand 2a pierced with a series of holes not visible in the drawing and another 2 b at the end of which is a metal loop 3 with a pin 3a.
  • the loop 3 is rectangular or at least that the transverse part 3b against which the free end of the pin normally abuts either substantially straight and extends almost over the entire width of the bracelet.
  • box 1 it has been shown as being round in the three figures, but it could just as easily be rectangular, oval or of another shape.
  • its structure can be arbitrary provided that it has a metallic bottom 4.
  • this bottom 4 has in its central part an elongated and roughly straight boss 5 disposed substantially perpendicular to the longitudinal direction of the strands 2a and 2b of the bracelet.
  • the shape of this boss can be for example that of a rectangular parallelepiped, that of a prism with a trapezoidal section or that of a half-cylinder.
  • this shape of the boss 5 as well as its dimensions are chosen so that, on the one hand, it cannot hinder and is preferably invisible when the watch is worn on the wrist and that, on the other hand, it constitutes an obstacle which one cannot avoid or overcome very easily when, as one will see further, one is brought to slide the transverse part 3 b of the loop on the bottom of the box, in direction from him.
  • This watch also comprises two control devices constituted by two fixed contacts 6 and 7 which are incorporated in the bottom of the box so as to be electrically isolated and which are placed on either side of the boss 5, at a certain distance from it and roughly on the midline of the bottom perpendicular to it.
  • the contacts can be used for example one to advance and the other to delay it or else one to perform time zone changes, that is to change the display of one or more whole hours, and the other to set the time, that is to correct the indication of the minutes together or not with that of the hours. If the watch is more complicated, one of them can be provided to select an item of information (hours, minutes, day of the week, date, wake-up time, wake-up minute, etc.) and the other to correct it.
  • the transverse portion may firstly apply 3 b of the buckle 3 against the bottom of the box in the region which lies between this contact and the strand to the nearest band, as as shown in the figure, then move it towards the boss 5.
  • the contact is actuated when the loop passes over it. To make it a second time just bring the loop back and if it is not enough we can then make it move back and forth on the bottom until the contact has been actuated the desired number of times.
  • part 3b of the loop is straight and long enough. It would not be the same if it were for example very rounded.
  • the boss 5 constitutes positioning means, in particular for the part 3b of the loop in that it limits the displacements of the latter on the bottom of the box to areas in which the contacts are and that it can help to keep it parallel to him therefore to decrease the always very low probability that it misses these contacts when it is subjected to the back and forth movement which one has speak.
  • the metal base 4 of the watch in FIG. 2 also has a boss 8 but this has substantially the shape of an H.
  • the transverse bar 8a of the H is arranged in the same way as the boss 5 of the watch of Figure 1 and has a length equal or slightly greater than that of the cross portion 3b of the loop 3 of the bracelet.
  • the two side bars 8 b and 8 c of the H are shaped so as to have facing flanks 8 d and 8 e roughly perpendicular to the bottom 4 or at least quite strongly inclined relative to the latter and which deviate from each other when moving away from the crossbar 8a.
  • the watch again has two fixed electrical contacts which are designated by the same references 6 and 7 as those in FIG. 1 because they are identical and must be actuated in the same way. The only difference is that they are not at a certain distance from the boss but in the immediate vicinity of the crossbar 8a so that, to activate them, the part 3b of the loop must be brought into abutment against this bar.
  • the transverse bar 8a of the boss and a small part of each side bar located near it therefore in this case form precise positioning means for the part 3b of the loop.
  • the rest of the side bars 8 b and 8 c serve to guide the part 3 b towards these positioning means when it is brought into contact with the bottom 4 and when it is slid onto it.
  • this embodiment may suggest another wherein the H-shaped embossment would be replaced by a boss-shaped and wherein X either by the transverse portion operable contacts 3b of the loop but by the barb 3a would be placed close to the crossing point of the X bars.
  • the watch of FIG. 3 has only one contact 9 placed in the middle of the back and identical to the contacts 6 and 7 of the watches of FIGS. 1 and 2.
  • the back 4 no longer has only one boss, designated here by the reference 10, but also a groove 11 which are both approximately rectilinear and perpendicular to the longitudinal direction of the bracelet and which are located on either side of the contact 9, substantially equidistant from him.
  • the groove 11 1 which is on the side of the strand 2 b of the bracelet which carries the buckle 3 has a length slightly greater than that of the transverse part 3 b of the latter and, preferably, a semi-cylindrical shape or slightly close so that this transverse part can engage in it and come out of it quite easily when you slide it on the bottom.
  • the boss 10, for its part has a shape and dimensions which allow it to meet the same requirements and play the same role, in particular with respect to the buckle as that of the watch in FIG. 1.
  • the groove 11 which allows to place this part 3b in the middle of the bottom and roughly parallel to it and to the boss 10 if it was not already there and which, therefore, guarantees the subsequent actuation of the contact.
  • the groove 11 therefore serves as prepositioning means for the loop.
  • the groove is associated with the boss 10 to limit the amplitude of this movement and to more or less maintain part 3b in the direction she imposed on him at the start.
  • the watch of Figure 4 comprises a box 12, for example rectangular, to which is fixed in a way one metal strap 13 provided with a folding clasp 14 consists of three articulated pads 14a, 14 b and 14 c.
  • the way in which the box 12 is produced is even more indifferent than in the case of the preceding watches because it is not even necessary for its base 15 to be metallic.
  • the bottom 1 has two grooves 16 and 17 substantially parallel to each other which extend in the direction of the width of the box and at the bottom of each of which emerge two fixed electrical contacts 18, 19, respectively 20, 21, which, to be actuated, must be connected together by a metallic object. Naturally, if the bottom of the box is itself metallic, the contacts must be isolated.
  • grooves 16 and 17 it should also be specified that their length and width are chosen so that it is easy to engage the parts of the clasp in which the hinges 14 d and 14 e are located which join the plate from the middle 14b to the other two 14a and 14, or, at least, one of these parts.
  • they are quite far from each other but not too close to the edges of the box. A good compromise is to make them divide the length of the latter roughly into three equal parts.
  • the manner of actuating one or the other of the pairs of contacts by means of the clasp 14 is obvious. Just bring the hinge 14 d or 14 e in the right groove, as shown in the figure. If you want to actuate the same pair of contacts several times, you can either take the hinge out of the groove each time and bring it back then, or keep it pressed on one of the contacts and move it aside only the other.
  • the first solution is perhaps more convenient from a handling point of view, but if it is used it may take longer to activate the contacts the same number of times as using the second.
  • the watch of Figure 4 has certain advantages over those of Figures 1 to 3.
  • the contacts are better protected against involuntary actuation and, unlike what can happen with bosses, the grooves 16 and 17 are not likely to affect the aesthetics of the watch and there are no precautions to be taken so that the wearer is not bothered by their presence.
  • it is still easy to operate the contacts, it is a little less than in the case of previous watches.
  • a variant of this watch of FIG. 4 could be obtained by replacing the grooves 16 and 17 by two cylindrical or, preferably, conical holes situated on the longitudinal center line of the bottom, the opening of which would be sufficiently large so that one can find them easily and at the bottom of each of which would be placed a contact that could be actuated by connecting it to the bottom 15 which, in this case, would necessarily be metallic or a push button.
  • the wrist strap buckle As actuating means it is sufficient that one of the pads 14a, 14b or 14c extends beyond the hinge which connects it to another with a point adapted to the shape and the dimensions of the holes, such as that which can be seen in FIG. 4a and which is designated by the reference 14 f .
  • this point should also be shaped and placed so as not to hinder or risk injuring the wearer.
  • the watch in FIG. 5 has the same case 12, the same strap 13 and the same pairs of contacts 18, 19 and 20, 21 as that of FIG. 4.
  • the only difference is that the grooves 16 and 17 are replaced by two recesses 22 and 23 of more complicated shape.
  • Each recess has on the side of the bottom of the bottom 1 5 an abrupt longitudinal flank 22a, respectively 23a, at the foot of which is the pair of contacts, another longitudinal flank 22 b , respectively 23 b , slightly inclined, opposite the previous one, and two lateral flanks which on either side of the bottom where the pair of contacts is located are parallel to each other and which then move away from one another when they border the inclined plane.
  • each recess would have only one inclined plane and two flanks forming a V at the bottom of which would be placed a push button or a contact actuable by a point which would have the clasp.
  • the bottom 25 of the box 24 has a single recess 26 with an abrupt flank 27 somewhat in the form of a sinusoid whose general direction is substantially perpendicular to the longitudinal direction of the bracelet 29 and a plane 26 inclined towards this side.
  • the invention is not limited to this kind of positioning and guiding means and, to show that it is possible to remain within the framework thereof even while moving far away from the forms of '' execution which have been described we can cite the example of a watch in the bottom of which would be incorporated at least one pastille made of magnetic material, with just behind, an electromagnetic relay, and whose closure member of the bracelet could be fitted with a small permanent magnet to activate the relay.
  • One could even provide in addition, as guide means in the bottom, one or more tracks also made of magnetic material which would lead to the pellet.
