Description

  The present invention relates to a stand-up assistance device that mainly assists the start-up of a care recipient after using a toilet.

  When a care recipient uses a toilet, the center of gravity of the body moves backward from the foot when sitting on the toilet seat, and after using the toilet, the center of gravity moves backward from the foot. It is not easy for care recipients because of the burden. Therefore, conventionally, as a device for assisting the rising of a care recipient after using the toilet, for example, a toilet seat lifting device for moving up and down the toilet seat described in Patent Document 1 has been proposed.

  Conventionally, as the above-described assistance device, for example, a toilet seat lifting device that tilts the toilet seat described in Patent Document 2 forward with a lifting bias spring, and a four-bar non-parallel link mechanism that supports the toilet seat described in Patent Document 3 on the left and right A toilet seat lifting device has been proposed that facilitates the movement of the center of gravity by urging the body with an electric linear drive mechanism and tilting it forward while lifting the toilet seat to push up the buttocks.

In addition, for example, a seating / standing support device described in Patent Document 4 has been proposed as a sitting and standing assistance device for a care recipient, and in this device, a holder is attached to the tip of a fluid pressure cylinder, and the holder needs to be installed. While supporting the caregiver's buttocks from below, the holder can be moved up and down along the movement locus of the caretaker's buttocks to assist the care recipient in sitting and standing.
