Definitions

  • the present invention relates to a portable wrist case by means of a bracelet and having a keyboard supported, neither by the case, nor by the bracelet but associated with the latter.
  • the keyboard has keys for entering data in a processing unit contained in the case also comprising a display device for displaying the data entered or the result of a particular treatment, and an energy source to power the components e.
  • This portable case preferably has the shape of a wristwatch.
  • the wristwatch having become an almost indispensable accessory in everyday life, and therefore worn permanently on the wrist, we sought him incorporate other functions that have become just as essential to a user as the knowledge of the time. It was thus incorporated into the case of the wristwatch additional functional devices allowing for example to have a calculator, compass, thermometer, biological function (e.g. rhythm cardiac), telephone and many more.
  • additional functional devices allowing for example to have a calculator, compass, thermometer, biological function (e.g. rhythm cardiac), telephone and many more.
  • there is a need for more areas of differentiated pressure that is to say a keyboard with keys.
  • US Patent 4,255,801 describes an electronic watch comprising a calculator having a bracelet with links with embossed number buttons on one side and on the other side raised keys for the calculation functions.
  • US patent 4,141,074 all the keys of the calculator are carried by the same strand of bracelet. All the keys are connected to a central processing unit located inside the case by a strip of conductive wires, passing from one link to another to finally cross the housing. In such a construction, it is obvious that there is a risk of deterioration of the strip of conductive wires when handling the bracelet in torsion and especially in traction when the wristwatch is attached to the wrist, or conversely when removed.
  • US Patent 5,020,039 describes a flexible bracelet made up of two bands elastomers sandwiching contactors whose locations and functions are printed on the upper strip. So there are no more links articulated, or raised keys, which removes some of the disadvantages mentioned above.
  • the proposed construction does not, however, solution to the risk of breakage of the conductive wires connecting the contactors, during a traction on the bracelet, and the aesthetic appearance has only slightly improved.
  • the present invention aims to overcome the drawbacks of the prior art mentioned above by providing a case which can be fixed to the wrist by means of a bracelet with no keyboard, but which also protects and protects hide an underlying keyboard allowing the input of alphanumeric data and / or functional in a processing unit contained in the housing.
  • the invention relates to a portable housing comprising means for attaching a bracelet to a wrist and means for connecting a flexible support a keypad with alphanumeric characters or signs function corresponding for example to a calculator keyboard or a keyboard simplified computer.
  • the keyboard is connected inside the case to a unit of data processing controlling a display device allowing to display on a dial of the box of characters provided by the processing unit, the power supply electrical components of said display device and unit treatment being provided by an energy source.
  • the housing is characterized in that the flexible support of the keyboard is connected to one side of said housing having a length corresponding substantially to the wrist and in that the bracelet completely covers the keyboard, being provided with a fixed attachment means diametrically opposite to the keyboard connection means and an attachment means removable located at said connection.
  • the case is a watch case also containing a movement allowing functions to be displayed on the dial timetables in analog or digital form.
  • keyboard is completely hidden and protected and the wristwatch looks of all wristwatches, which allows great variations on the plan aesthetic.
  • a 1A wristwatch with digital display It conventionally includes a housing 2 housing in particular a timepiece circuit 9 whose electronic circuits or blocks which compose it will not be described in detail as being known to the man of profession in the field of watchmaking.
  • the timekeeping circuit 9 controls a conventional matrix-type liquid crystal display device 6, supported by a dial 7 protected by a crystal 8.
  • the case also contains a source of energy 10 which is for example a battery or an accumulator rechargeable by any means known in the technical field of the invention.
  • Case 12 of case 2 also includes push buttons 5 for controlling the time functions of the watch and / or an additional non-time function such as this will be explained later.
  • the watch 1A is attached to the wrist by means of a bracelet 3 which has on one side of the middle part 12 a fixed fastener 4b rotatably mounted on an axis and on the diametrically opposite side a removable fastener 4a formed by a mounted loop rotating on the middle 12 and in which one engages and returns the end 3a of the bracelet strand 3 comprising a Velcro® type attachment.
  • bracelet 3 is designed to wrap the wrist and does not extend only on one side of the housing 2, as shown in Figure 2, when it is detached from the wrist and placed on a flat surface.
  • the watch 1A is provided a keyboard 13, independent of the bracelet 3 and fixed to the case 2 at a zone 12a of the middle 12, diametrically opposite to the fixed attachment 4b of the bracelet 3.
  • a keyboard 13 When the wrist watch 1A is placed on a flat surface, only a small portion of the removable clip 4a hides the keyboard 13.
  • the keyboard 13 When, on the contrary, the watch is attached to the wrist, the keyboard 13 is entirely hidden and protected by the bracelet 3, as shown in Figures 1 and 3, the separation between these two elements having been greatly exaggerated for a better understanding. In reality when the watch is worn on the wrist, these two elements are pressed one against the other the other.
  • the internal surface of the bracelet 3 has a shape complementary to that of the keyboard 13 to allow, in a way, to fit it and hide it completely.
  • the keyboard 13 is a calculator keyboard having keys 14 carrying numbers and signs of functions registered to be read perpendicular to the length of the keyboard 13, that is to say in the same direction as time display 6.
  • the keyboard 13 is connected to a processing unit 29 housed in the housing 2 and allowing to have on the dial 7 a liquid crystal matrix display 16 of the data entered via the keyboard 13 and the result of the operation performed.
  • Switching to calculator mode can be carried out in a very usual way by pressing a key for a fixed period, for example more than 2 seconds 15 bearing the sign C.
  • a key for example more than 2 seconds 15 bearing the sign C.
  • this delayed activation prevents unwanted passage calculator mode if a brief shock or pressure is accidentally exerted on the button 15 via the bracelet 3, for example if the latter is made in a flexible material. It is also possible to plan to switch to calculator by pressing one of the push-buttons 5.
  • the two time displays 6 and calculation 16 are separated. According to an alternative embodiment, it is possible to have only one liquid crystal matrix display by providing in the processing unit 29 means for switching between time mode and calculator mode, or conversely when pressing the button 15 or on a push button 5 as previously indicated.
  • a wristwatch 1B with analog time display by means of hands 26, comprising a keyboard 23, as previously connected to the case 2 opposite the fixed clip 4b of the bracelet 3.
  • the keyboard 23 includes keys 14 identified by inscriptions alphanumeric and functional corresponding to those of a computer keyboard simplified. As can be seen, unlike the first embodiment, these inscriptions are readable parallel to the length of the keyboard 23 and can be arranged in three rows and be covered by bracelet 3 without detracting from the appearance aesthetic when the watch is worn on the wrist.
  • the keyboard 23 is, as previously, connected inside the housing 2 to a processing unit 29 for controlling a liquid crystal matrix display that can have several lines 16a, 16b, ...
  • the passage of hands 26 above the digital display areas 16a, 16b, ... constitutes a gene acceptable.
  • the gene caused by needles can be eliminated by opting for a digital display of time.
  • the bracelet 3 is, as previously, in one piece with a fixed clip 24 opposite the keyboard 23, and a removable clip in two clip-on parts, part 25 being mounted at rotation above one end of the keyboard 23 and comprising a cutout 25a in which engages a tongue 27a of the second part 27. It is good obvious that the skilled person can adapt certain other fastening systems intended for bracelets with two strands to a bracelet comprising only one, as is the case for the present invention.
  • FIG. 5 there is shown in perspective partially torn off a key 14 of an alphanumeric character from the keyboard 13 or 23 made mainly of a rubbery material.
  • a circuit strip flexible print 32 for example a Capton® film, carrying metallic tracks 20 on at least one of its faces is sandwiched between two strips 31 and 33 in one rubbery materials.
  • the first strip 31 is shaped to carry out the keys 14 and the second strip 33 to support the flexible printed circuit 32.
  • Each button 14 in the form of a truncated cone comprises under its upper part a conductive pad 14a forming a contactor when pressed to short-circuit two metal tracks 20.
  • the elasticity of the material makes it possible to bring the pellet 14a back to the rest position, that is to say distant tracks 20.
  • the keys alphanumeric and functional 14 of the keyboard 13 or 23 can be keys capacitive or piezoresistive sensitive to the approach or contact of the finger of a user, these two technologies being well known to those skilled in the art.
  • Figure 6 schematically shows the electronic components necessary for the transmission of electrical signals between keys 14, 15 of the keyboard 13 or 23 and the components integrated in the housing 2, the keyboard being represented only by a portion of the flexible printed circuit 32 close to the middle 12 and by the extension 32a inside the case 2.
  • the flexible printed circuit 32 includes an integrated circuit encoding 19 connected on the one hand by metal tracks 20 to a series of switches 14a, on the other hand by two metal tracks 17, 18 which extends over the portion 32a inside the housing up to the processing unit 29 supplied by the energy source 10 and connected to a drive circuit 30 of the display device 6 or 16a, 16b, ....
  • the integrated encoding circuit 19 receives clock signals from a block generator and includes a microprocessor clocked by the oscillator block or a wired logic to send in series on line 18 the binary word corresponding to the symbol of the key pressed so that this word is processed by the processing unit 29.
  • the processing unit 29 can be a microcontroller clocked at a frequency of the order of 32 KHz supplied by a quartz oscillator block (not shown). He is at note that the oscillator block of the integrated encoding circuit 19 and that of the processing 29 can be the same as that of the timepiece circuit 9 of the watch.
  • the integrated encoding circuit 19 offers the advantage of having only two tracks metallic 17, 18 communication between the keyboard 13 or 23 and the inside of the housing 2 and thus allow mechanical reinforcement of said tracks.
  • the keyboard 13 or 23 not being subjected to any tensile stress, it is perfectly possible to save on the integrated encoding circuit 19 by connecting all the tracks 20 of the contactors 14a directly to the processing unit 20.
  • the upper strip 31 made of material rubbery can extend a little beyond the crossing of the middle 12 and constitute with the lower strip 33 a seal at this level.
