Although these devices can functionally support the startup operation, they have the following problems in actual use. In the first place, people instinctively hate being pushed from behind, and sometimes even feel a sense of fear. Therefore, the assistance is based on the operation of pulling the person who needs assistance to the person who needs assistance or holding the person who needs assistance. From this point of view, the operation of pushing up the buttocks as disclosed in Patent Document 1 gives a sense that the person requiring assistance is pushed, so it seems that it is better to avoid using it as much as possible. Although the apparatus disclosed in Patent Document 2 does not have such a problem, it imposes an excessive burden on the muscles of the forearm that supports the weight, and is not very suitable for use by persons with weak physical strength. In addition, since the body is supported only by the arm that grips the grip portion, the posture is likely to collapse during the standing up motion, which is extremely dangerous. In this regard, in the apparatus disclosed in Patent Document 3, the person requiring assistance only needs to keep his / her body and can stand up relatively easily. However, it can be painful in some cases due to the concentration of the whole body weight under the armpits. Also, because both arms are just hanging, some people may feel a little anxious.

The present invention has been made to solve the problems associated with the conventional techniques, and an object of the present invention is to provide a stand-up assisting device that allows a person receiving assistance to stand up safely without feeling uneasy. is there.
