Description
Technical Field
The present invention relates to a bedside structure, and more particularly, to a bedside structure having a side rail at a side of a bed.
Background
Conventionally, side fences (hereinafter, referred to as side rails) are attached to both side portions of a hospital bed used in a hospital or the like, a nursing bed used in a care of a special institution, a home, or the like, to prevent a bed user, bedding, or the like from falling off the bed. The side rail is usually detachably attached to a side frame of the bed, and is detachable when not needed (see patent document 1).
However, the conventional method has the following problems: the removal of the side rails is complicated, and it is necessary to secure a space for placing the removed side rails.
As a countermeasure against the above problem, a structure is conventionally proposed in which the side rail is retracted to the lower side of the bed side portion without being removed, but the following problem arises.
For example, when the side rails are housed below the bed bottom plate that supports the mattress, the bed needs to have a certain height in order to ensure a space for operating the side rails and a space for housing the side rails, and it is difficult to reduce the height of the bed.
Further, when the side rails are folded and compactly stored under the bed bottom, the side rails have a complicated structure and need to be designed with strength in mind, which causes a problem of high cost.
In addition, when the side rails are not stored below the bed bottom plate but outside the bed bottom plate, a storage space is not required below the bed bottom plate, and thus the bed can be lowered.
Specifically, there is proposed an apparatus having a side rail structure in which a side rail is moved up and down in accordance with a use situation of a user as a link structure capable of vertically displacing the side rail (see patent document 2).
According to the structure of patent document 2, the side rail can be easily retracted without being detached. In addition, since the lower side of the mattress can be used as a space for housing a part of the link structure or the constituent member of the bed, the design of the link can be easily performed.
