Abstract

A device for measuring forces or a weighing device includes at least one sensor, at least one force input device configured to elastically deform in relation to an external force acting on the device, and a casing coupled to the sensor and the force input device. The sensor is configured such that, when the force is applied to the device, the sensor detects the force in relation to the elastic deformation of the force input device, and the casing is configured to accommodate the sensor in the casing in at least two different positions.

First claim

What is claimed is:

1. A device for measuring forces, comprising:
at least one sensor;
at least one force input device configured to elastically deform in relation to an external force acting on the device; and
a casing coupled to the sensor and the force input device,
wherein the sensor is configured such that, when the force is applied to the device, the sensor detects the force in relation to the elastic deformation of the force input device, and
wherein the casing is configured to accommodate the sensor in the casing in at least two different positions

wherein the casing comprises a circular cylindrical shape of a predetermined height
wherein a first side of the casing comprises a recess of a predetermined depth,
wherein a second side of the casing comprises a first recess of a predetermined depth and a second recess of a predetermined depth;
wherein the casing comprises a step of a predetermined height, and a recess of a predetermined length, and
wherein the casing further comprises an elongated hole of a predetermined depth.

2. The device of claim 1 ,
wherein the sensor is an inductive sensor and/or wherein the force input device is made from an electric conductive material.

3. The device of claim 1 ,
wherein the sensor includes at least one of a coil, a magnetic core, an oscillator, a demodulator, a flip-flop, a comparator, an output stage, and a printed circuit board.

4. The device of claim 1 ,
wherein the sensor is enclosed by the casing or wherein the sensor is partially enclosed by the casing.

5. The device of claim 1 ,
wherein the sensor further comprises an integrated RFID communication device, configured such, that depending on the acting force the sensor communicates data to an external device using the integrated RFID communication device.

6. The device of claim 1 ,
wherein the force input device comprises a circular disk shape,
wherein the force input device is of an elastic material, and
wherein at least one protrusion is provided at a center position of the force input device, and
wherein the protrusion is orientated away from the casing.

7. The device of claim 1 ,
wherein the force input device and/or the sensor are/is coupled to the casing using glue.

8. The device of claim 1 ,
wherein the force input device ( 104 ) and the casing ( 106 ) are arranged concentrically.

9. The device claim 1 ,
wherein the casing is made of Polyamide 12, and/or wherein the force input device is made of steel.

10. A weighing device for weighing of objects, comprising:
a plurality of devices each including:
at least one sensor;
at least one force input device configured to elastically deform in relation to an external force acting on the device; and
a casing coupled to the sensor and the force input device,
wherein the sensor is configured such that, when the force is applied to the device, the sensor detects the force in relation to the elastic deformation of the force input device, and
wherein the casing is configured to accommodate the sensor in the casing in at least two different positions; and

at least one support panel,
wherein each device is arranged at an edge corner portion of a first surface of the support panel, respectively; and
wherein the devices are coupled to the first surface of the support panel such, that at least one device is coupled to the support panel using a first side of the device, and that at least one further device is coupled to the support panel using a second side of the further device, wherein the second side is an opposite side of the first side

wherein the support panel comprises a plate shape of a predetermined height and is made of an electric conductive material;
wherein at least one edge portion of the support panel comprises an U-turned portion;
wherein the U-turned portion is configured to partially overlap at least one device of the plurality of devices;
wherein the U-turned portion of the support panel and the at least one sensor are configured such that, when a force is applied to the force input device using the support plate, the at least one sensor measures a change in an electromagnetic field generated by the sensor due to movement of the respective U-turned portion, and
wherein the sensor is partially enclosed by the casing.

11. The weighing device of claim 10 ,
wherein adjacent devices of the plurality of devices are coupled to the support panel using alternating the first side of the device and the second side of the device.

12. The weighing device of claim 10 ,
wherein a portion of the support panel is configured to accommodate an electronic device, and
wherein the electronic device is configured to communicate with at least one sensor of the at least one device, and is further configured to communicate data to an external device using Radio-Frequency-Identification (RFID) transmission.

13. The weighing device of claim 10 ,
wherein at least one device is coupled to the support panel using glue.
