Title:
ベッド用荷重センサ及びこれを用いたベッド用荷重計測システム
Document Type and Number:
Japanese Patent JP7311110
Kind Code:
B2
Abstract:
To provide a bed load sensor which offers great flexibility when installed while maintaining the accuracy of detecting the load of bed, and a bed load measuring system using the load sensor.SOLUTION: A bed load sensor 3 comprises a leg placement face 46 on which the legs of a bed are placed, a plurality of strain parts 5, and a strain sensor 6. The plurality of strain parts 5 has a support face 513 facing an installation face, and is constituted so that when a load is applied to the leg placement face 46 while the support face 513 is in contact with the installation face, strain is generated in at least some of the strain parts. The strain sensor 6 measures the strain generated in the strain parts 5. The plurality of strain parts 5 has a first strain part 53 located at a position corresponding to the leg placement face 46 and at least three second strain parts 54 existing in the periphery of the first strain part 53. The support face 513 of the first strain part 53 is located downward of a virtual plane that includes the support face 513 of the second strain parts 54.SELECTED DRAWING: Figure 2
