Multi-functional bed

Abstract

In a multifunctional bed in which a variable bed that can be changed into a wheelchair form is fitted in a U-shaped fixed bed, when a seat back portion of the variable bed is laid or raised, the variable bed may assume an unstable position, thus hindering a smooth form change. The present invention provides a multifunctional bed comprising a variable bed 3 that can be changed into a wheelchair form and a fixed bed 2 in which the variable bed 3 can be removably fitted, wherein a holding member is provided between the fixed bed 2 and the variable bed 3, for holding a vertical position of the variable bed 3 relative to the fixed bed 2, and the holding member comprises a vertical pair of guide rails 141, 143 disposed on a left and right inner side surfaces of a notched recess portion 20a of the fixed bed 2 formed so as to appear substantially U-shaped, and guide rollers 131, 133 disposed on both sides of a seat back portion 34 of the variable bed 3 Fig. 1B).

Description

technical field [0001] The present invention relates to a kind of multifunctional bed which is composed of a variable bed which can change the shape of the wheelchair and a fixed bed which can be freely attached and detached to the variable bed. A mechanism that maintains its up and down position. Background technique [0002] Conventionally, various nursing beds have been developed and provided as necessary for nursing care of patients in nursing facilities, hospitals, or homes. These care beds are used to make the care receiver sleep in a horizontal state. According to the occasion, the bed itself can be bent into the shape of a chair with a backrest. [0003] As a conventional bed for nursing care, when the care receiver is moved to another place, it is necessary to prepare another wheelchair, and in addition, it is necessary to prepare a lifting device for the care receiver to get on and off the wheelchair. [0004] In addition, research and development of multifunctio...

AI Technical Summary

Problems solved by technology

[0006] However, when the above-mentioned variable bed in the form of a wheelchair is fitted in the cutout recess of the fixed bed, when the backrest of the variable bed is put down or erected, the position of the center of gravity of the care receiver will be lower than that in the wheelchair form. The position of the rear wheels of the variable bed is also shifted to the rear. During the form change, the variable bed is in an unstable posture, and there are cases where the form conversion cannot be carried out smoothly.
