Alternatively, there is an advantage that the user can get on and off.

[Problems to be solved by the invention]

However, such a conventional elevating bed is intended for a general so-called healthy person, and can walk to himself or use a wheelchair to some extent, but gets up on the bed by himself,
Elderly people who need assistance to lie down,
No particular consideration is given to the sick or disabled. That is, in the conventional elevating bed, like a normal bed, when shifting from a sleeping position to a sitting position with the upper body raised, or from a sitting position to a sleeping position,
It is painful for such elderly people to require considerable abdominal muscle strength and arm strength, etc.In addition, there are people who suffer severe pain in bending such as bending their waist or twisting their body while applying force The points such as many are not considered.

Some commercial special beds in hospitals, etc., have a reclining mechanism so that the electric backrest can be turned upside down, but the bed itself is fixed in height or slightly adjustable in height. However, it is still inconvenient for the elderly and the like to get on and off the bed on their own, and the configuration of the reclining mechanism is complicated and expensive. Furthermore, even if such a reclining mechanism is to be incorporated into an elevating bed, there is a problem that the bed base is large and heavy, and the overall structure requires a high-strength one, which is very expensive. there were.

The present invention has been made in view of such problems, and has as its object to provide an elevating bed incorporating a simple and economical reclining mechanism.

[Means for solving the problem]

In order to solve the above-mentioned problem, the present invention fixes a base to a bed support frame, and attaches a pulley to an arm whose tip projects above one end of a bed to be raised and lowered, and through this pulley. One end of a fixed-size wire is connected to one end of the bed base of the bed, and the other end is connected to one end of a bed floor panel that is bendable at an intermediate portion, thereby forming a stretched state. It is an object of the present invention to provide an elevating bed provided with a characteristic reclining mechanism.

According to the present invention, one end of a fixed-length wire is connected to a bed base via a pulley attached to an arm, and the other end is freely bent at an intermediate portion. Since the bed cradle is lowered, the other end of the stretched wire can raise the one end of the bed floor panel and stand up in a reclining state. The other end of the wire is lowered, and the bed floor panel in the reclining state can be turned down to a horizontal state. In other words, one side of the bed floor panel is automatically moved up and down with the vertical movement of the elevating bed, so that the upper body of the occupant can be lifted without requiring the power of the occupant or forcing the occupant to take an unreasonable posture. Can be raised and put to bed. Further, since the bed floor panel is reclined at the low position, the occupant can easily get out of the bed from a sitting state.
