    ELECTRONIC WEIGHING EQUIPMENT EQUIPPED WITH A SURPLUS Technical field
    The present invention relates to the field of electronic weighing apparatus which comprises a load receiving tray and an electronic processing system for activating functions by pressing on the load receiving tray. These weighing devices consist in particular of scales that can include scales with impedance meter and baby scales, and household scales.
    State of the art
    It is known electronic keyboard weighing devices integrated in the tray receiving the load. The patent EP0852329B1 describes a weighing apparatus comprising a load receiving tray, a weighing structure incorporating one or more weight sensors that support the receiving tray and an electronic processing system configured to display the mass. the load or to activate functions on the weighing apparatus, said functions being associated with bearing positions on the receiving tray. These bearing positions are materialized on the receiving plate by markings constituting control keys.
    It is also known weighing devices with receiving trays with a variety of decorations so that the owner can have a custom weighing device. SUMMARY OF THE INVENTION The object of the invention is to implement electronic weighing devices that can be customized and adapted to the best of each owner or user. To this end, the invention relates to an electronic weighing apparatus which comprises a weighing structure provided with at least one weight sensor, and a receiving plate configured to receive a load, said receiving plate being supported by said at least one a weight sensor. The weighing apparatus also comprises an electronic processing system connected to the at least one weight sensor by means of first connection means. The electronic processing system is configured to activate functions associated with respective bearing positions on the receiving tray, i.e. coordinates of the center of gravity of a load positioned on the receiving tray, this load being in this case a finger of a user who presses on the receiving tray to activate one of the functions. This electronic processing system is also configured to calculate the mass of a load disposed on the receiving tray. The weighing apparatus also comprises an electronic display, for example a liquid crystal display, connected to the electronic processing system by means of second connection means, which is configured to display in particular the weight of the weighed load and the activated functions.
    In addition, remarkably, the weighing apparatus comprises an over-board configured to be attached to the receiving plate, on which control buttons corresponding to the different support positions defined on said receiving tray are formed and allowing activation of said functions. The choice of the activation of the functions by the electronic processing system on the basis of the calculation of the coordinates of the center of gravity of the load (the position of support of the finger), authorizes the addition of an extra thickness on the plate of receiving without altering the calculation of said coordinates. Thus, it is possible to report the on-tray on the receiving tray, without affecting the proper operation of the electronic processing system when placing a load on the receiving tray. This design advantageously makes it possible to relate overhangs which have different surface states or reliefs, for example a corrugated, ridged, smooth, or embossed surface, and different decorations, for example color and / or pattern variants. These overhangs can also be implemented in different materials, for example a silicone material, a thermoplastic material or a thermoformed textile material. The user can thus adapt his electronic weighing device according to his tastes and needs.
    Preferably, the electronic processing system is configured so that the selection of the mode of calculating the mass or the activation mode of the functions depends on the intensity of the load pressing on the receiving plate and the position of support of the load on the receiving tray. When a load to be weighed is positioned on the receiving tray, the at least one weight sensor is subjected to deformation stresses which are transmitted to the electronic processing system, which calculates the coordinates of the center of gravity of the load and an intensity proportional to said constraints. Since this intensity has a value greater than a reference intensity, it is translated by the electronic processing system into a value of the mass of the load. This value of the mass is then displayed by the electronic display. On the contrary, when the user wishes to activate a function, it presses with a finger on a defined position on the receiving tray. The at least one weight sensor is then subjected to stresses, which also allows the electronic processing system to calculate an intensity proportional to these stresses and the coordinates of the center of gravity of the load on the receiving plate. that is to say the support position with the finger on the over-tray and, indirectly, on the receiving tray. Due to the low value of the intensity, lower than a reference intensity, and the bearing position corresponding to a position defined on the receiving plate, the electronic processing system activates a function corresponding to said position of defined support.
    According to a first embodiment of the electronic weighing apparatus object of the invention, the bearing positions are marked by markings on the receiving tray, these markings being associated with the various functions. In addition, the control keys are predefined on the platter in positions corresponding to the markings. This design simplifies the use of the electronic weighing device, the user simply having to report the on-tray on the receiving tray and use the various functions of said device by pressing the control buttons on the -tray.
    According to a second embodiment of the electronic weighing apparatus which is the subject of the invention, the electronic processing system is configured to record support positions and associate them with the various functions, said support positions being defined as a function of the materialization. control keys on the on-board. This variant embodiment can be implemented by adapting the programming of the electronic processing system. This design advantageously allows the user complete freedom in the implementation and materialization of the control keys on the tray, so as to make it more ergonomic. The user can, for example, paint the control keys or report self-adhesive pads to the desired positions on the platen, and then program the positions of the control buttons via the electronic processing system.
    It is also possible to combine the two aforementioned embodiments, that is to say materialize markings on the receiving tray which are associated with the various functions, while providing an electronic processing system which makes it possible to modify the support positions. on the receiving tray and associate them with said functions, despite the presence of the markings, so as to allow the user to report an on-board with control keys already materialized and corresponding with the markings, or to report one on -plateau on which the control keys are materialized at the free choice of the user, without taking into account the markings on the receiving tray.
    According to the invention, the reception tray comprises an electronic display as mentioned above, in particular in the form of a reading screen, and the overhang comprises a transparent window configured to be superimposed on the electronic display when it is put in place. on said receiving tray. This makes it possible to report an on-tray of identical dimensions to the receiving tray, so as to cover it completely. However, it is possible to envisage implementation variants for which the electronic display is remote from the load receiving tray, in this case the on-board has no transparent window.
    In a preferred embodiment of the weighing apparatus, the on-plate is removable, which allows it to be easily removed, for example to clean its surface with water or any other product, without affecting the electronic components of the machine. weighing machine. In an alternative embodiment, there could be an on-plate reported and fixed on the receiving plate, for example by means of double-sided adhesive pads or fixing screws.
    In one embodiment of the weighing apparatus, the weighing structure comprises four weight sensors arranged to be positioned under the four corners of the receiving tray. Other variants are however possible, including a single weight sensor consisting of a metal bar on which are arranged strain gauges for measuring in two directions the moments of the force applied to the sensor.
    The number of functions on the weighing machine varies greatly depending on whether it is a scale, a weighing scale with impedance meter, a scale or a household scale. Preferably, the weighing apparatus according to the invention comprises between two and eight functions which are respectively associated between two and eight support positions on the receiving tray, the on-tray comprising respectively between two and forty control keys.

    detailed description
    In the rest of the description, the same references are used to describe the similar characteristics according to the different embodiments. In addition, the term "apparatus" will refer to the electronic weighing apparatus according to the invention unless otherwise indicated.
    As illustrated in FIG. 1, the apparatus 1 comprises a weighing structure 2 which is provided with a pedestal 3 or weighing base and with weight sensors 4, said apparatus also comprising a receiving plate 5 of a charge. The number of weight sensors 4 is variable, according to the configuration of the apparatus 1. For example, in FIGS. 1 and 3 to 5, the weighing structure 2 comprises four weight sensors 4 which are arranged at the four corners of the base 3 and which respectively support the four corners of the receiving tray 5. In FIG. 6, the weighing structure 2 comprises a single weight sensor 4 in the form of a metal bar 6 extending transversely in central part of the base 3. The bar 6 is provided with strain gauges 7 which measure the deformations of the bar 6. A first end 6a of the bar 6 is supported by the base 3 and a second end 6b of said bar 6 supports the receiving plate 5 .
    As illustrated in FIGS. 5, 6 and 9, the apparatus 1 comprises an electronic processing system 8 which comprises an electronic circuit 9 connected to the weight sensors 4 by means of first connection means 10 of electric wire type. This electronic circuit 9 retrieves the data (in the form of electrical signals) representative of the deformations experienced by the weight sensors 4 due to the presence of a load 11 on the receiving plate 5. Then this electronic circuit 9 restores data ( also in the form of electrical signals) representative of the intensity I of the load and the X, Y coordinates of the center of gravity of the load 11 on the receiving tray 5. When this load 11 is a finger that presses the tray receiving 5, the center of gravity corresponds to the support position. The electronic processing system 8 then compares this intensity I with a reference intensity IR. When the intensity I is greater than the reference intensity 1R (1> 1R), the electronic processing system 8 transmits the information to a first calculation module 12 which determines the mass of the load 11 as a function of the intensity I. When the intensity I is less than the reference intensity IR (l <1R), the electronic processing system 8 transmits the information to a second calculation module 13 which activates a function associated with the position of support of the load 11 on the receiving plate 5. In FIG. 7, the apparatus 1 comprises six functions associated with six load bearing positions 11 represented by markings 14a, 14b, 14c, 14d, 14e, 14f on the receiving plate 5. In FIG. 8, the apparatus comprises five functions associated with five positions of support of a load 11 represented by markings 14a, 14b, 14c, 14d, 14e on the receiving plate 5 The number of functions associated with the same number For example, the shadow of load support positions 11 may vary between two and forty. These functions are, for example, the change of unit of measurement from the load of the gram to the pound, the choice of the user weighing himself, the recording of the value of the mass measured in a memory 15, the activation of a timer 16 ... The apparatus also comprises an electronic display 17, illustrated in FIGS. 1, 3, 4, 7 and 8, for example a liquid crystal display, which is connected to the first and second calculation modules 12 , 13 of the electronic processing system 8 through second connection means 18 of the electric wire type. This electronic display allows the display of the mass of the load and certain activated functions, such as the choice of the user, the unit of measure, the countdown of a timer. In FIG. 7, the electronic display 17 is arranged directly on the receiving plate 5.
    On the contrary, in FIG. 8, this electronic display 17 is offset on the base 3, outside the reception plate 5.
    As illustrated in Figures 1 to 4, the apparatus 1 also includes an overhang 19 configured to be attached to the receiving tray 5 without altering the center of gravity. For this, the on-plate 19 is of identical dimensions to the receiving plate 5 and has a homogeneous mass distribution over its entire surface. The on-plate 19 can be simply placed on the receiving plate 5, so that it can be removed easily. However, it is possible to provide fastening means between the on-plate 19 and the receiving plate 5, for example an adhesive film on the lower face 19b of the overhang 19. It is also possible to provide a peripheral rim on the contour 19c of the on-plate 19 so as to wedge it properly by embedding when it is positioned on the receiving plate 5. As illustrated in FIGS. 1 to 4, the on-plate 19 comprises a transparent window 21 which is superimposed on the electronic display 17 when said on-plate 19 is positioned on the receiving plate 5.
    In FIG. 1, the on-plate 19 comprises control keys 20a, 20b, 20c which are materialized on its outer face 19a. When the on-plate 19 is positioned on the receiving plate 5, the control keys 20a, 20b, 20c correspond with the positions of the markings 14a, 14b, 14c materialized on the receiving plate 5.
    As explained above, the electronic circuit 9 calculates the X, Y coordinates of the projection of the center of gravity of the load 11 on the receiving plate 5, which advantageously allows the addition of the on-plate 19 without affecting the calculation of said X coordinates, Y since the center of gravity of the load 11 is not changed, the only difference being that the load 11 is applied to said on-tray 19 rather than the receiving tray 5. Figure 2 illustrates a variant on-plate 19 to that illustrated in Figure 1, the only difference being the surface condition of the outer face 19a which is bumpy rather than smooth. Of course, other variants are possible without departing from the scope of the invention, for example an outer face 19a corrugated or corrugated. It is also possible to envisage different materials and different patterns for the design of the top plate 19. Preferably, the overhang 19 is opaque to completely conceal the receiving plate 5.
    Figures 3 and 4 illustrate another variant in which the on-plate 19 initially has no control button, these being subsequently materialized by the user according to his convenience, once said on-plate 19 in position on the receiving plate 5. For this, the second calculation module 13 of the electronic processing system 8 integrates a routine program for storing the X, Y coordinates related to the on-plate 19 in position on the receiving plate 5. which are assigned to each function existing on the device 1, so as to activate these functions by pressing with the finger on these coordinates, once the memory sequence has been performed. For example, when the user maintains pressing a finger 22 on the platen 19 for a period of 5 seconds, or by a predetermined sequence of supports, the second calculation module 13 can initiate the function memory sequence, the first function appearing on the electronic display 17, said X, Y coordinates of the first function being validated by the second calculation module 13 while maintaining the finger 22 resting on said X, Y coordinates for a few seconds, and so on for the X, Y coordinates of the following functions also materialized by means of stickers 23a, 23b, 23c. The control keys 20a, 20b, 20c may be materialized prior to the initialization sequence of the functions, for example by means of the stickers 23a, 23b, 23c glued on the outer face 19a of the on-plate 19 or any other marking with a pencil or paint, illustrating numbers, letters or drawings.
    In this variant of Figures 3 and 4, markings 14a, 14b, 14c, 14d are materialized on the receiving plate 5 and allow the activation of functions associated with them. This makes it possible to position upright trays 19 with pre-materialized control keys 20a, 20b, 20c or, on the contrary, upright trays 19 on which the control keys 20a, 20b, 20c are positioned at the convenience of the user. user by means of stickers 23a, 23b, 23c or any other means. However, it is possible to envisage a variant of apparatus 1 on which no marking 14a, 14b, 14c, 14d is materialized on the receiving plate 5, the user having to automatically start an initialization sequence in this case in order to memorize the coordinates. X, Y functions according to the positions of the control keys 20a, 20b, 20c which it wishes to define, during the first use of the apparatus 1. This possibility of choosing the positions of the control keys 20a, 20b, 20c allows to better adapt the device 1 to the conditions of use and / or ergonomics of the location of the device 1. The programming of the second calculation module 13 can also be configured to allow the storage of certain functions only among all possible, which allows to better adapt the device 1 to his needs.
    The foregoing description has no limiting character, many device variants 1 being conceivable without departing from the scope of the invention.
