< Topic >The bed for nursing which ascent and descent it can point the patient whose weight is heavier is offered.SolutionsThe bed for nursing this invention has had two ascent and descent motors which are connected to the height control possible lifter mechanically in parallel. Load is given to two ascent and descent motors equally, in order to avoid the occurrence of twisting power to the lifter, the balance circuit which measures the power source electric current of the ascent and descent motor is provided. When it is judged, if there is an electric current difference between the ascent and descent motors, in order for mutual electric current to get near, motor electric current of husband is cut off brief.< Selective figure >Figure 4【課題】より体重が重い患者を昇降させる介護用ベッドを提供する。【解決手段】本発明の介護用ベッドは、高さ調節可能なリフタに機械的に並列に結合された2つの昇降モータを有している。2つの昇降モータに均等に負荷を与え、リフタへのねじり力の発生を避けるために、昇降モータの電源電流を測定するバランス回路が設けられている。もし昇降モータ間の電流差があると判断されると、互いの電流が近づくように、夫々のモータ電流が短時間遮断される。【選択図】図4
