Definitions

  • the present invention relates to alarm devices for timepieces.
  • the subject of the invention is an alarm device which is intended more particularly for an electric clock-clock and which is one of those in which a buzzer is triggered by the coincidence of a first point of contact linked to a gear train timetable included in the timepiece with a second contact point linked to an index whose position can be adjusted by a manual control member.
  • the index generally consists of a needle which is carried by a barrel wheel engaged on the barrel of the hour wheel and which can be moved by turning a button.
  • the object of the invention is to provide an alarm device which can be even more so.
  • the second point of contact is linked to a part secured to a rotary shaft on which pivot the moving parts of the clockwork of the timepiece which carry hands indicating the time.
  • This action can be exerted for example by means of a button formed or fixed to one of the ends of this tree and located at the back of the clock as a button for setting the classic wake-up time or at the front of it as a button for setting the clock on the vehicle dashboard.
  • the invention also aims to provide a solution to this problem.
  • This solution consists in making the rotary shaft of the alarm device integral with the crystal of the timepiece and in fixing this crystal on a rotating bezel in order to allow these two elements to be used as a manual control member.
  • any mark can be provided on the glass, for example a colored, glued or painted arrow, which serves as an index, which is generally easier and more economical than fixing a wake-up needle on the rotating shaft. .
  • the alarm clock which is shown in Figures 1 and 2 comprises a plastic part 2 which forms both a foot 4, a cylindrical housing 6, with an edge 8 and a bottom 10, which is carried by the foot 4 , a plate 12 disposed inside the housing 6, perpendicular to its axis and a wall 14 for supporting this plate.
  • This clock also includes a round glass of transparent plastic material 16, the internal face of which has an annular projection 18 in the middle and the edge of which is fixed, for example by gluing or ultrasonic welding, to a bezel 22 also made of plastic, the outside diameter is substantially equal to or slightly greater than that of the housing.
  • the annular projection 18 has inside two edges 20 parallel to the axis of the glass and diametrically opposed, the usefulness of which will appear later.
  • the outline of its profile is roughly in a quarter of a circle, but it could also have another shape.
  • part 2 also forms a number of uprights which start from the plate 12 and from the bottom 10 and at the ends of which is fixed a disc also made of plastic 28, which is centered on the axis of the housing 6 and parallel to the plate 12 and whose diameter is equal to that of the internal cylindrical wall 24 of the bezel 22.
  • Figure 2 shows only one of these amounts designated by the reference 30. Like the others, it has at its top a tenon 32 which passes through a hole 34 of the disc and whose end has been flattened to form a head 36 and to take the edge of the hole 34 between this head and the bearing which is at the limit between the tenon 32 and the rest of the upright . This could be done for example by melting the end of the post by means of ultrasound so as not only to produce the head 36 but also to weld it to the disc.
  • the hole 34 is located at the bottom of a small bowl 38 so that the head 36 does not exceed the front face of the disc and that this face can directly carry a dial 40 fixed on it for example by gluing and same diameter as the disc.
  • this disc has at its periphery and at the rear an annular notch 42 which has the same width as the lip 26 of the telescope and in which the latter is engaged.
  • the disc 28 has at its periphery a number of regularly spaced notches 44, for example six, and as many radial tabs 46 which start from the bottom of these notches to go almost to the edge of the disc.
  • these tabs 46 are thinner than the disc in order to be able to have a certain elasticity in the direction perpendicular thereto.
  • each of them has at its end and on the side of the rear face of the disc a stud or a small shoe 48, the end of which is at a level between the planes in which the rear faces of the disc are located. and its thinned peripheral part 50.
  • the bezel 22 When the clock is mounted, the bezel 22 is taken axially between the edge 8 of the housing and the pads 48 which press on the lip 26 and it can rotate in both directions, with the glass and around its axis, being guided by the range of the disc which is at the limit between its rear face and that of its thinned part.
  • This role of the disc 28 which consists in collaborating with the edge of the case to maintain the lens and the bezel in an axial position and to guide the latter in rotation is in fact the second that is reported, the first being that of supporting the dial.
  • This disc also plays a third: it serves as a stage for the movement of the clock. This is the reason why we can see in FIG. 4, in addition to a central hole 52 and notches 44, tabs 46 and holes 34 which have already been mentioned, a certain number of round holes for mounting. parts of the movement and a larger rectangular hole for the coil of a stepper motor which is normally attached to the back of the disc.
  • the plate 12 has two hollow cylindrical protuberances 54 and 56 on the bottom side of the housing.
  • the first, 54, of these protuberances constitutes a bearing in which is engaged one of the ends of a plastic shaft 58 which passes through the disc 28 and the dial 40 in their center and which extends to the projection annular 18 of the glass into which it penetrates and to which it has been fixed by simply being forcefully inserted therein.
  • the two internal edges 20 of the projection have themselves hollowed out corresponding grooves in the end of the shaft, which means that the ice does not run the risk of turning without carrying the latter with it.
  • This shaft 58 which obviously constitutes the rotary shaft of which we have spoken is formed here in one piece with a disc 60 whose rear face is very close to or in contact with the plate 12 and whose front face has a cylindrical boss of low height 62 in the middle as well as several smaller bosses 64 and even less high near its periphery.
  • bosses 64 which can be for example three in number, serve as feet for a circular plate of material conductor, more precisely a metal plate 66 which has been fixed on them using for example the ultrasonic welding technique and which has a diameter slightly greater than that of the disc 60.
  • This metal plate 66 has on the side opposite the disc a small rounded boss 68 which constitutes the second point of contact of the alarm device of the clock.
  • this boss 68 is located at the end of a tongue 70 which has been formed in the plate 66 by cutting out an opening 72 and which has in its central part a round hole 74 through which the central boss 62 of the disc passes.
  • the tongue 70 which has a certain elasticity, can fold down in the space which separates the plate from the front face of the disc and return to its normal position when the pressure on the boss stops.
  • an hour-barrel wheel 76 also made of plastic, which comprises on the one hand a tube 78 at the end of which is fixed a hour hand 82 and, on the other hand, an hour wheel proper 80.
  • This hour wheel 80 has on its rear face a central flange 84 whose outside diameter is equal to the diameter of the boss 62 of the disc 60, with which it is in contact, and bosses 86 which, like the bosses 64 of the disc, constitute feet on which a circular metal plate 88 is fixed.
  • this plate 88 has a small rounded boss 90 situated at the end of an elastic tongue formed in the same way as the tongue 70 (see FIG. 5).
  • This boss 90 which constitutes the first point of contact of the alarm device of the clock, and the boss 68 of the plate 66 are obviously substantially the same distance from the axis of the shaft 58 in order to be able to meet and pass one over the other by forcing the tabs that carry them to slightly deform when the hour wheel turns relative to the disc 60 or vice versa.
  • the hour barrel wheel is carried by a carriageway on which is fixed a minute hand and this minute hand is located in front of the hour hand.
  • a pavement 92 is mounted around the barrel 78 of the hour barrel wheel 76 and the minute hand 100 which is carried by this pavement is closer to the dial than the hour hand 82.
  • the roadway 92 which may for example be metallic, comprises as usual a tube 94 at the end of which the needle 100 is fixed, a minute pinion 96 and a minute wheel 98 which are obviously all integral.
  • the minute wheel 98 is coupled by means of several intermediate mobiles to the rotor of the motor of which we have spoken, which is fixed to the rear of the disc 28 and which is conventionally controlled by an electronic circuit which comprises a quartz oscillator, a frequency divider and a pulse forming circuit for generating and applying driving pulses to the motor coil in response to the pulses supplied by the divider.
  • the minute pinion 96 is coupled to the hour wheel 80 by means of a timer mobile 104.
  • This timer mobile 104 which can be made for example of plastic, comprises a hollow central tube 106, a timer wheel 108 which meshes with the minute pinion 96 and a timer pinion 110 which is engaged with the wheel of the 80 hours.
  • the shaft 106 can pivot at one of its ends around a pivot 112 located at the end of an upright 114 and provided at the rear of the disc 28 and at its other end inside a protrusion 116 in the form of a hollow cylinder portion and a hole 118 in the plate 12 which communicates the interior of this protuberance 116 with that of the protuberance 56 provided on the other side.
  • the clock also includes a button 120 which is located at the rear of its case.
  • This adjustment button 120 forms a single piece of plastic material with a time-setting rod 122 which passes inside the protuberance 56 and which ends in a tip 124 of smaller diameter which is engaged. inside the tube 106 of the timer mobile 104.
  • this rod 122 has two diametrically opposite dishes below the end piece 124 which engage in two corresponding axial notches of the tube 106.
  • this same figure shows very schematically how the electrical alarm circuit is made up of which the metal plates 66 and 88 form with their contacts 68 and 90.
  • This circuit comprises two brushes, for example two metal blades 126 and 128 which are each in contact with the rear face of one of the plates 66 and 88 and which rub on these plates when they rotate.
  • One, 126, of these brushes is connected directly to the negative pole of the supply voltage source 130 of the clock.
  • the other brush 128 is connected to the positive terminal of this same source by means of a switch 132, the opening and closing of which can be controlled by means of a button 138 which is placed at the top of the clock and that can be seen in FIG. 1, and a circuit 134 for controlling a buzzer 136.
  • the crystal 16 of the clock carries on its periphery an index, more precisely a black or colored arrow 140 which is glued or painted on its internal face and which is wholly or mainly at- above an area of the dial 40 which surrounds its graduations, so as not to mask some of these.
  • the circuit 134 controls the buzzer 136 and the latter then emits an audible signal, this of course provided that the button 138 is for example raised and the switch 132 closed. Otherwise, nothing happens.
