  By the way, in the armrest which concerns on patent document 1, when the engagement protrusion provided in the hollow shaft and the engagement hole formed in the movable shaft are engaged, it is the plurality of engagement holes formed in the movable shaft. Some of them were exposed to the outside. If an attempt is made to adjust the height of the armrest in this state, the user or caregiver may accidentally put his finger into the engagement hole exposed to the outside. When the height of the armrest part of the armrest is changed with the finger placed in the engagement hole exposed to the outside, the user's finger is sandwiched between the engagement hole exposed to the outside and the upper end of the column and pressed. There was a risk of injury.

  The portable toilet proposed here includes a toilet body and an armrest provided on the toilet body. The armrests are installed at a position where the armrests are provided, a pair of hollow struts arranged respectively on the front and back of the toilet body, a pair of movable shafts inserted through the struts and sliding with respect to the struts, and the movable shafts. An armrest portion and a height adjustment mechanism for adjusting the height of the movable shaft with respect to the support column are provided. A plurality of engagement holes are formed in the movable shaft along the longitudinal direction. The height adjustment mechanism is provided on the support column, and is movable in a state where it protrudes into the movable shaft so as to enter the engagement hole and a state where it is retracted from the protrusion state so as to come out of the engagement hole. A protrusion, and an operation portion for operating the engaging protrusion in the protruding state and the retracted state are provided. The engagement hole is provided with finger padding prevention means for preventing a user or caregiver's finger from entering the engagement hole.

  According to the portable toilet, it is possible to prevent the finger of the user or caregiver from entering the engagement hole of the movable shaft. Therefore, when adjusting the height of the armrest portion of the armrest, it is possible to prevent the finger from being injured by being pressed between the engagement hole of the movable shaft and the support column.

For example, when the height of the movable shaft with respect to the support column is adjusted, among the engagement holes formed in the movable shaft, at least a part of the engagement hole is disposed above the support column and disposed above the support column. The possible engagement hole may be provided with finger filling prevention means.

  For example, the finger filling preventing means may be a protrusion extending from the edge of the engagement hole to the engagement hole. At this time, the engaging protrusion may include a groove in which the protrusion is received.

  For example, the protrusion may extend upward from the central portion of the lower edge of the engagement hole. At this time, the engagement protrusion may have a shape that can match the shape of the engagement hole excluding the protrusion.

  For example, the base end portion of the engagement protrusion may have a distance along the length direction of the support column longer than a distance along a direction orthogonal to the length direction of the support column.

  For example, the movable shaft and the engagement protrusion may be made of resin.

  For example, the support post may be formed with an insertion hole through which the engagement protrusion is inserted. The height adjustment mechanism includes a spring seat disposed opposite to the insertion hole on the outer side of the support column, and a spring mounted in a compressed state between the engagement protrusion and the spring seat. The engaging projection may be pulled outward of the support column with respect to the insertion hole against the elastic reaction force of the spring.

  For example, it may be arranged so that the insertion holes face each other, and the armrest may include a hollow shaft that communicates with the insertion hole. The spring seat may be disposed at an intermediate position of the hollow shaft. The spring may be mounted between a spring seat and an engagement protrusion that is built in the hollow shaft and is inserted through the insertion hole.

  For example, the height adjustment mechanism may include an operation member along the inner peripheral surface of the hollow shaft. A spring is accommodated in the operation member, and an engagement protrusion may be provided at the end of the operation member on the end side of the hollow shaft.

  For example, the operation part protrudes from the outer peripheral surface of the operation member to the outside of the operation member, and the operation part is inserted through the hollow shaft, and the guide part allows the operation part to slide along the axial direction of the hollow shaft. May be formed.
