The bed also comprises a first and a second auxiliary mat adapted to close said defecating hole, a first auxiliary mat support plate lifting means disposed movable longitudinally of the bed below the housing portion of said first auxiliary mat adapted to close the excrement receptacle disposed portion of said defecating hole, a second auxiliary mat support plate disposed beneath the housing portion of the second auxiliary mat adapted to close the leg side portion of said defecating hole, said second auxiliary mat support plate being movable vertically pivoted at a suitable leg side part of said defecating hole, a truck on which is removably rested an excrement receptacle having an openable front covering which can be set at any desired angle conforming to the body structure of the user within the range of the maximum inclination, said truck being disposed beneath said second auxiliary mat support plate and supported so as to be movable synchronously with the first auxiliary mat lifting means, said truck and second auxiliary mat support plate being articularly joined by bars or other like means such that said second auxiliary mat support plate will take a horizontal position when said truck is located at a position just beneath the buttocks of the user or at a position remotest from the user's buttocks, and that said second auxiliary mat support plate will take an upwardly moved position when said truck stays at an intermediate position, said front covering of said excrement receptacle being connected to a suitable part of the second auxiliary mat support plate by a string or like means through the medium of an elastic body so that said front covering will be opened up in accordance with turning motion of said second auxiliary mat support plate caused by parallel movement of said truck from the retracted non-use position to the position of use immediately below the user's buttocks.</p> |
