Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a measuring instrument. In particular, it is suitable for weighing relatively heavy and fragile or easily damaged or bulky items.

[0002]

[Prior art]

 Conventionally, as a measuring instrument, a spring scale using a tension and a repulsive force of a spring and a platform scale using a lever are known. In addition, electronic scales using voltage have also appeared.

[0003]

[Problems to be solved by the device]

 The conventional spring scale has a drawback that metal fatigue occurs due to repeated long-term use of the spring, and the measurement is likely to be distorted. In addition, the platform scale is mainly used for weighing heavy objects, but since the device is long, the installation location is troublesome, and transportation, maintenance and management are not easy. Furthermore, a quiet place that is horizontal and free of vibration is required. The electronic scale, which displays a measurement based on the frequency from the transmission circuit that incorporates a variable capacitor whose electrostatic capacity changes according to the weight, is suitable for lightweight and precise items, but it is suitable for heavy items. Not suitable for bulky items. Also, troubles are likely to occur during extreme weighing work. On the other hand, in the present invention, since mechanical elements such as springs and gears are scarcely present, there is no deviation due to metal fatigue. In addition, it does not have to be a horizontal and quiet place, it does not easily cause troubles like an electronic scale even when doing a little extreme weighing work, and since it is a mat, it is possible to fold the main part and make it compact. It is a convenient measuring instrument that is extremely convenient to store and transport.

[0004]

[Means for Solving the Problems]

 A mat body 2 in which a large number of elongated airtight air bags 1 filled with a constant amount of air are uniformly integrated in parallel is formed, and an air supply pipe 3 is arranged at each end of the airtight air bag 1. It has been set up. The air supply pipes 3 are connected to the collecting pipes 4 and introduced into the pressure detecting means 5. This pressure signal is input to the calculating means 6 and is digitally displayed on the digital display 7.

[0005]

[Action and Example]

 When the heavy object A is placed on the upper surface of the mat body 2, the air in the airtight air bag 1 is compressed in proportion to the weight due to the pressing force. The air pressure subjected to this weight is immediately collected in the collecting pipe 4 via the group of the air supply pipes 3 and simultaneously transmitted to the pressure detecting means 5. Further, this pressure signal is input to the calculating means 6 and its numerical value is digitally displayed on the digital display 7. The airtight air bag 1 is preferably made of a rubber-tipped cloth or a durable airtight sheet such as soft plastic. Further, in order to enhance the durability and the impact resistance, a protective plate 8 made of rubber or the like is adhered to each top of the airtight air bag 1. The pressure detecting means 5, the calculating means 6 and the digital display 7 are powered by a storage battery 10 charged by a solar battery 9.

[0006]

[Effect of device]

 As described above in detail, the mat-type pneumatic weighing device of the present invention has few mechanical elements such as springs and gears, and therefore does not suffer from deformation caused by metal fatigue or the like. Also, it can be used without being limited to a horizontal and vibration-free place, and it does not cause any trouble even if a little extreme weighing work is performed. In addition, since the main part can be folded and made compact, it is convenient for storage and transportation. Furthermore, since the power source for detection and display can be supplied by the solar cell, no expense or maintenance cost is required. The power source can of course be supplied from a household power source, or both of them can be used together. Further, the present invention provides a useful idea in which the size of the mat body 2 and the like can be appropriately designed according to the purpose, such as for home use and business use.
