Definitions

  • the invention relates to a balance with an electrical force measuring device for measuring a weight force and with a display device for displaying the weight force.
  • the force measuring device is located in an area between a support frame and a so-called weighing pan or a receptacle for such a weighing pan.
  • a weight force can be measured using the force measuring device if the base frame is placed on a flat surface.
  • the known scales are also limited in terms of design. Often these have a base frame which is designed as a housing with a square or round base. A movable weighing pan support is attached thereon, a force measuring device extending between the base frame and the weighing pan support.
  • this object is achieved in that two force measuring devices which can be acted upon independently of one another each are provided, the force measuring devices being connected to one another in such a way that one force measuring device is designed to be movable with respect to the other.
  • the force measuring devices can be rotated relative to one another and / or displaced in translation.
  • both the basic housing and the weighing pan support of the known scales are superfluous. If two or more force measuring devices that are independent of one another are used, then these advantageously take over the task of stably supporting the goods to be weighed on a base area.
  • a force measuring device in the sense of the invention is to be understood as a device which rests on a contact surface and measures a weight force which acts on the contact surface starting from an object mounted on the device.
  • the force measuring devices or their support arms can be folded together if no measurements are carried out, which results in good transportability in the folded state.
  • the axis of rotation can run essentially perpendicular to the main directions of extension of the support arms. Then the support arms can be opened like the legs of an angle.
  • the force measuring devices can then represent at least three support points for an object, the Weight force should be measured.
  • the object to be measured is stable on these at least three support points, so that a reliable measurement result is obtained.
  • the stability of the scales according to the invention can be increased by providing safety cams in the area of the support arms which additionally support the scales when they tip over the contact points of the force measuring devices.
  • the scale according to the invention also has a reset button for comparing the scale in a basic state and / or for switching on the scale.
  • Reset key allows the balance to be brought into a defined basic state before a weighing process by setting the zero point.
  • the weight of changing objects can also be determined in a known manner, for example a plate placed on the scales, from which food is removed. That way it can
  • the weight of each individual food removed can be determined precisely if the balance is "zeroed" each time before parts of the food are removed.
  • the scales are built so flat that they can be arranged from a plate in the area below the plate when dishes increase, without this being noticed in the immediate vicinity of the eater.
  • force sensors made of pressure-sensitive film can be used, for example, which are embedded in film-like force arms. In this way, scales can be manufactured that are easy to transport and that are not noticeable in use.
  • the scale can also have an evaluation unit with a substance database. Then measurement results can be directly in desired sizes such as volume or
  • Energy content can be converted.
  • a connection to external computers is also provided, for example in order to forward measurement results to the computer or to wait for data provided in the balance.
  • 1 to 3 show a first balance according to the invention in the folded state in one
  • Figure 4 shows the scale from Figures 1 to 3 in the unfolded, ready for use state
  • Figure 5 shows the scale from Figure 4 with an attached
  • FIG. 8 and FIG. 9 show a further balance according to the invention.
  • Figures 1 to 3 show a scale 1 m in a three-sided view.
  • the scale 1 is divided into a basic body 2 and two support arms 3 and 4 which are rotatably attached to the basic body 2
  • Support arms 3, 4 are pivotally attached to the base body 2 via pivot axes 5, 6 which run perpendicular to the direction of extension of the support arms 3, 4.
  • FIG. 4 shows the balance 1 with the support arms 3, 4 pivoted away from the base body 2.
  • the force measuring devices 7, 8 and 9 can be designed, for example, as a pressure film or as a deformation measuring device, in which a mechanical deformation is converted into a corresponding electrical signal.
  • An electrical evaluation circuit not shown here, is provided in the interior of the base body 2, which adds the forces measured by the force measuring devices 7, 8 and 9 and displays the result on a display 10 provided on the base body 2.
  • a reset button 11 is attached to the base body 2.
  • the scale 1 takes in the folded state, i.e. when the support arms 3, 4 are pivoted to the base body 2, only a small amount of space.
  • FIG. 5 shows the scale 1 from FIGS. 1 to 4 in a state in which it is loaded by a plate 12 indicated here with dashed lines.
  • a base ring 13 of the plate 12 loads the force measuring devices 7, 8 and 9 at standpoints 14, 15 and 16.
  • the contact forces measured there are added together and shown on the display 10.
  • the plate 12 is stable on the three stand points 14, 15 and 16, so that the plate 12 can even be cut and eaten.
  • the base body 2 protrudes only slightly beyond the rim 12, so that it is only accessible to the user of the plate 12.
  • the presence of the scale 1 under the plate 12 is almost invisible to bystanders.
  • FIG. 6 shows a further scale 20 with a base body 21 and only a single swivel arm 22 which can be swiveled with respect to the base body 21 via a swivel axis 23 which is essentially perpendicular to the direction of extension of the base body 21 or the swivel arm 22.
  • a linear force measuring device 24 or 25 is provided in the area of the swivel arm 22 and the base body 21, a linear force measuring device 24 or 25 is provided.
  • FIG. 7 shows the scale 20 from FIG. 6 in the ready-to-use state with an attached plate 26 which rests on the force measuring devices 24 and 25 via a base ring 27. He touches them at uprising points 28, 29, 30 and 31.
  • the weight measured by the force measuring devices 24 and 25 is shown on a display 32 which is on one of the
  • Axis of rotation 23 remote end of the pivot arm 21 is provided.
  • a reset button 33 is used to operate the scale 20.
  • the weight measured by the force measuring devices 24 and 25 is shown on a display 32, which is provided in the region of the end of the swivel arm 21 located at the axis of rotation 23.
  • FIGS. 8 and 9 show a further scale 20, which is structurally similar to the scale 20 from FIGS. 6 and 7. The same parts therefore have the same reference numbers.
  • the scale 20 has force measuring supports 34, 35 and 36, which the
  • a force measurement support 34 is attached in the region of the pivot axis 23, while the other two force measurement supports 35 and 36 are attached to the end of the base body 21 and at the end of the pivot arm 22, as can best be seen in FIG.
  • the weight measured by the force measuring devices 24 and 25 is shown on a display 32, which is provided in the region of the end of the swivel arm 21 located at the axis of rotation 23.
  • FIG. 9 shows the scale 20 from FIG. 8 in the ready-to-use state with an attached plate 26 which rests on the force measuring devices 24 and 25 via a base ring 27. He touches them at uprising points 28, 29, 30 and 31.

Abstract

L'invention concerne une balance (20) présentant deux dispositifs de mesure de force (21, 22) pouvant être soumis à un poids, indépendamment l'un de l'autre, et un dispositif d'affichage (32) indiquant la somme des poids. Ces dispositifs de mesure de force (21, 22) sont reliés l'un à l'autre de sorte qu'un dispositif de mesure de force (21) peut tourner par rapport à l'autre dispositif de mesure de force (22). Cette conception permet de replier les dispositifs de mesure de force (21, 22) et par conséquent de faciliter le transport de cette balance. Trois détecteurs (34, 35, 36) sont prévus au niveau des dispositifs de mesure de force (21, 22).
