Description

  The present invention relates to a shoe for a care recipient that can be easily attached and detached by a care recipient by himself / herself.

  Conventionally, 70% to 80% of people who have a nursing care level of 3 to 4 or more and who are in nursing care facilities have difficulty in putting on and taking off their own shoes. Need.

  However, in care facilities, caregivers are taking care of their caregivers who leave their beds day and night in a bent posture, especially at around 30 caregivers at night. Since care is taken, the movement gives a heavy burden to the caregiver's body and causes back pain.

  As a result, caregivers may suddenly develop low back pain during the care operation and become unable to move, or the back pain gradually becomes worse and even walking becomes difficult, and it takes days for the back pain to recover. This is an important issue not only for facilities and caregivers, but also for those requiring care.

  In order to solve such a problem, Patent Literature 1 proposes a shoe for a care recipient who can easily attach and detach the shoe by himself / herself. The shoe for the care recipient described in the document incorporates a leaf spring-like insole holding plate that urges the rear end side of the insole upward.

  When wearing shoes, slide the foot into the shoe from the toe side along the insole whose back end side is obliquely raised by the insole holding plate, and step on the insole with the heel. It moves downward with the insole against the elastic biasing force, and the rear end engages and holds the locking tongue at the bottom of the shoe's heel side, so that the foot's heel side fits in the shoe. Can be worn.

  Also, when taking off shoes, hitting the rear end of the shoe sole against the floor surface, etc., the locking tongue is pushed by the foot heel and disengages from the rear end of the insole holding plate. The back end of the board warps due to its elasticity, so that in this case as well, the foot can be easily extracted from the shoe by itself.
