2. Description of the Related Art A conventional nursing bed includes a bed that raises and lowers the back plate and raises the body while the care recipient is lying on the bed, a bed that tilts the care recipient sideways to prevent bedsore, There have been proposed ones that change the direction of the body by rotating a part or all of the body, or those that change the direction of the body after raising the cared person. Regarding the mattress of the nursing bed, various proposals have been made to support the two-dimensional movement of the nursing bed and make it easy to bend in a certain direction.

[0003]

However, any of the nursing care beds is limited to a two-dimensional movement that only raises the care receiver or turns the care receiver sideways. After raising the caregiver,
In the case of changing the body direction, the back and forth movement mechanism of the back plate and the bed rotation mechanism are independent of each other. Therefore, when moving the care recipient from a bed to a wheelchair, move the care recipient from a bed to a wheelchair, and let one person hold the care recipient's shoulders. One person had to move with two legs. When the caregiver was alone, the caregiver was sitting on the bedside while placing his or her hands on the cared person's neck and knees and rotating about the cared person's waist before moving. However, in any case, the caregiver has to change the posture of the caregiver from the bedside in a forward leaning posture, and there is a problem that the burden on the caregiver is large, such as a burden on the waist of the caregiver. In addition, care receivers who can support themselves to some extent cannot take a posture sitting on the bedside by themselves, so they can move to a wheelchair, practice standing up, In spite of being able to do things around them, they have been left asleep, and the cared person's independence cannot be improved. Further, in the case of rotating a bed, a large-sized device is required for rotating the bed, and a large space for rotating the bed is required. Various types of mattresses used for these nursing care beds have been proposed which are easily refracted two-dimensionally. However, the mattresses cannot cope with three-dimensional movements, and the mattresses shift or have irregular wrinkles. There have been problems such as poor sleeping comfort and causing bedsores.

[0004] In view of the above-mentioned problems of the prior art, the present invention raises the body of the care-receiver by raising and lowering the movable floor while keeping the care-receiver lying on the bed, In synchronization, the movable up-and-down floor portion is also horizontally displaced and rotated to automatically change the direction of the care receiver's body, or the up-and-down rotation displacement operation is performed by tilting the care receiver's body sideways. In addition, it is possible to turn the body sideways and change the body direction while raising the cared person, and furthermore, it is possible to move the cared person lying on the bed without changing the cared person's body direction At the same time as raising by the undulating operation of the undulating floor portion, the care receiver's body is tilted sideways in synchronization with the undulating operation. Change the posture of the caregiver The caregiver should be able to move the caregiver easily from the bed to the wheelchair, etc., to reduce the burden on the caregiver and to support the body to some extent by themselves. An object of the present invention is to provide a nursing bed that can take a posture of sitting on a bedside by itself.

Another object of the present invention is to provide a two-dimensional undulating operation for simply raising the body without changing the orientation of the care-receiver, and a three-dimensional undulating operation for simultaneously changing the body direction while raising the body. It is an object of the present invention to provide a nursing bed that can be used by switching between both moving operations.
Still another object of the present invention is to provide a mattress which can bend smoothly following the movement of the nursing bed.

[0064]

The nursing care bed of the present invention is embodied in the form described above, and has the following effects.

The nursing care bed according to the first aspect of the present invention can perform a three-dimensional movement such that the movable up-and-down floor is raised and simultaneously displaced in the horizontal direction by a simple structure. With this three-dimensional movement, the caregiver can raise the cared person and change the body direction at the same time, so that the cared person can be easily moved to a wheelchair or the like, and the burden on the cared person can be reduced. This has the advantage that the burden on the user is reduced. In addition, a cared person who can support himself to some extent can take a posture sitting on the bedside with almost no help from the cared person. As a result, you can move to a wheelchair yourself, rehabilitate,
In addition, since it is possible to do personal things, the independence can be enhanced without leaving the care receiver in bed.

The nursing care bed according to the second aspect of the present invention has a structure in which the back plate can be turned up and one side at the same time as the back plate is erected only by rotating one arm plate or two arm plates. It is possible to commercialize a nursing bed that moves easily and three-dimensionally at low cost.

In the nursing care bed according to the third aspect of the present invention, the back plate is divided into two and can be bent in a V-shape. Can be held between Therefore, it can be used safely even for a cared person whose nerve is paralyzed. Further, by dividing the back plate into two, there is an advantage that the degree of freedom in three-dimensional movement is increased and the rotational displacement operation of the back plate becomes smooth.

The nursing care bed according to claim 4 of the present invention is
The inclination angle of one of the backboards is larger than the inclination angle of the other backboard, so that when the care receiver is raised, the body can be raised while tilting sideways as if turning over.

In the nursing care bed according to the fifth aspect of the present invention, the care-receiver's body can be raised while keeping its sideways sideways, and the body can be turned to the bedside. When you get up, your legs move naturally toward the bedside. Therefore, when the care receiver or the caregiver throws out the legs to the bedside, the legs hang down on the bedside, and a vertical rotational moment acts around the waist, so that the upper body can be raised without requiring much effort, The posture sitting on the bedside can be easily taken. Further, since the arm plate is provided on each of the two back plates, when the back plate is turned upright, the load is distributed to the rotation support portions of the back plate and the arm plate, so that the upright rotation displacement operation is stable. And the durability of the nursing bed can be increased.

In the nursing care bed according to the sixth and seventh aspects of the present invention, since the lower portion of one back plate is free with respect to the fixed horizontal floor portion, the up-and-down rotation operation is smooth without applying excessive force. Done in By providing rollers at the lower end of the back plate, even when a load of the care-receiver is applied to the back plate, the turning and standing operation of the back plate is performed smoothly.

In the nursing care bed according to the eighth aspect of the present invention, since the support arm plate is provided between the back plate and the extension of the fixed horizontal floor, the mounting position of the support arm plate or the support arm member is provided. Depending on the length of the plate, it is also possible to change the change in the horizontal angle and the vertical angle of the undulation rotation displacement of the back plate, and the ratio of the refraction angle at the rotation support portion of the back plate determined thereby. In addition, it is possible to easily set the movement that is most suitable for the individual depending on the degree of disability of the cared person and the environment in which the person is placed. In addition, since each of the rotation supporting portions rotates in the vertical direction and the horizontal direction starting from the center point 0, three-dimensional movement can be freely performed.

In the nursing care bed according to the ninth aspect of the present invention, both the arm plate and the back plate or both the arm plate and the supporting arm plate are rotated and raised by the driving means, so that the load of the care receiver can be increased. Since the back plate or the supporting arm that is most affected by the movement is directly pushed up, the load is not concentrated on the rotation supporting portion or the like.

In the nursing care bed according to the tenth and eleventh aspects of the present invention, the direction in which the movable up-and-down floor portion is rotationally displaced can be changed in any of the left and right directions by changing the arm plate to be turned upright and the auxiliary arm plate. Since it can be set, there is an advantage, for example, when changing the setting of the rising direction by a right-handed person or a left-handed person, or when changing the direction of the upright rotation depending on the position of the care bed. In addition, since both the arm articulation plate and the auxiliary arm articulation plate are turned upright by the driving means, the load does not concentrate on a part of the rotation support portion or the like.

The care bed according to the twelfth aspect of the present invention is
Since the fixed horizontal floor and the arm articulation plate and the rotation support of the fixed horizontal floor and the auxiliary arm articulation plate are aligned with each other through the center point, the back plate and the auxiliary arm articulation plate are integrated by the raising and lowering operation frame. The two-dimensional movement of the undulating operation can be performed by a simple mechanism. Therefore, since the movement of the backboard can be selected from a two-dimensional operation in which only the undulation is performed and a three-dimensional operation in which the back plate is rotated and displaced, the nursing bed can be adapted to situations such as when eating or moving to a wheelchair. Can be used for a two-dimensional undulation operation and a three-dimensional undulation rotation operation, which is extremely convenient.

In the nursing care bed according to the thirteenth and fourteenth aspects of the present invention, the inclination angle of one of the back plates is increased in synchronism with the up-and-down movement of the movable up-and-down floor, so that the care-receiver's body can be turned sideways. Therefore, the cared person will get up in a sideways posture, raising the back to shift the center of gravity in the leg direction, making it easier to rotate horizontally around the waist, and the carer moving the cared person to a wheelchair. In addition, the cared person can take the posture of sitting on the bedside by throwing his legs to the bedside and hanging down, with self-help efforts or with a little help of the caregiver.

According to a fifteenth aspect of the present invention,
First, the care receiver's body is tilted sideways, and then the back is raised, so that the structure and operation are extremely simple, and a low-cost, easy-to-maintain nursing bed can be provided.

The nursing care bed according to claim 16 of the present invention is
A very simple mechanism that attaches to the fixed horizontal floor via a triangular arm plate with the lower end of the back plate perpendicular to the longitudinal direction of the bed and the vertex at the center, raises the cared person's body It is possible to easily perform only a two-dimensional operation and a three-dimensional operation that simultaneously raises the care receiver and tilts the body position.

The care bed according to the seventeenth aspect of the present invention is
The back plate can be raised by forcibly rotating and raising one of the arm plates using a cylinder utilizing air pressure, hydraulic pressure, etc., and the driving structure is simple.

The care bed according to the eighteenth aspect of the present invention,
The buttocks of the cared person are located in the notches, and the buttocks are not pushed forward due to the upright rotational displacement of the backboard. That is, if the notch is not provided, the buttocks are pushed forward and rise in an unnatural posture, but according to the present invention, since the back and head are pushed up from the waist,
Since the person can be raised and turned in an appropriate posture, the burden on the cared person is reduced.

Since the mattress of the nursing care bed according to the nineteenth aspect of the present invention bends following the three-dimensional movement, the mattress does not move and does not wrinkle irregularly. Therefore, it does not cause the care receiver to feel unpleasant or cause bedsores.
