Description

  The present invention relates to a bed apparatus that supplies power to a power-using device such as an electric actuator by a manual power generator.

In a bed device for care or medical use, various power-use devices such as an electric actuator for a bed driving unit and a measurement device for a care recipient or patient (hereinafter referred to as “care recipient”) are installed.
Caregivers and nurses (hereinafter referred to as “caregivers”, etc.) raise the back bottom so that the upper body can be raised about the posture of the cared person etc. on the bed device, and the knee bottom to ease the legs And the leg raising operation for raising the leg bottom is performed.

  When the operation of the bed device such as raising the back is performed with a mechanical handwheel, the motor operation is usually performed because it tends to be a work load for a caregiver or the like. As the power source for operation in that case, generally, a power source in a facility where a bed apparatus such as a nursing facility or a hospital is installed is used as described in Japanese Patent Application Laid-Open No. 2008-220603 (referred to as “Patent Document 1”). .

  In addition, the power supply in the facility is often installed on the wall near the bottom, preventing the power cord from touching the floor and making it unsanitary, or pinching the power cord between the bed lifting devices. In order to prevent such a problem, a cordless power supply device that generates power using a solar cell (solar panel) has been proposed by Japanese Patent Application Laid-Open No. 2011-160888 (referred to as “Patent Document 2”).

  However, when using solar cells, the installation location is limited because it is necessary to make it an installation location that can secure sufficient power generation in a room that is difficult to receive sunlight, and a battery that charges (stores) generated power is required. It will increase in size.
