electric bed

Abstract

Provided is an electric bed capable of realizing two forms of a horizontal state and an inclined state by using a small and simple drive mechanism, and realizes a light lifting bed with a tilt function and a small and light electric bed. The swing link (63) swings around the fixed rotation fulcrum (rotation shaft (37)). When the bed is at the highest bed height position, only the piston (54) of the lifting actuator (52) on the foot side is retracted, so that the connecting rod (62) rotates counterclockwise around the rotating shaft (47) . Thus, the part of the connecting rod (62) closer to the rotating shaft (64) than the rotating shaft (47) tends to rise, but since this part is connected to the swing connecting rod (63) via the rotating shaft (64), the connecting rod ( 62) Descending, whereby only the foot side part of the bed frame (40) is lowered by means of the rotating shaft (47) and the link support (45). Since the head side portion of the bed frame (40) is kept raised, the bed frame (40) is inclined.

Description

technical field [0001] The present invention relates to a lifting bed with a tilting function, which has a tilting function capable of adopting two states of a horizontal state and an inclined state, and also has a lifting function, and a back-lifting and knee-lifting bed with a function of raising and lowering the back bottom plate and the knee bottom plate Functional beds such as electric beds. In the present invention, when referring to the lifting bed, it also includes the concept of the lifting chair. Background technique [0002] In the treatment bed, in order to facilitate the doctor's diagnosis and treatment, and the nurse's care, the whole bed can be raised and lowered in a horizontal state. In addition, there are beds that allow the user on the bed to take a relaxed posture by raising or lowering the back floor to change the inclination angle of the back floor (Patent Documents 1 and 2). In particular, in the multifunctional bed described in Patent Document 1, in...

AI Technical Summary

Problems solved by technology

[0005] However, in the conventional tiltable bed devices disclosed in the aforementioned Patent Documents 1, 3, and 4, although the entire bed can be tilted, the bed cannot be raised or lowered.

In addition, in the conventional bed device disclosed in Patent Document 2, although the back floor can be raised and lowered, there is a problem that the entire bed cannot be tilted, and the bed cannot be raised or lowered.
