[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention basically comprises a base member, a column member which can be adjusted in height rising from the base member, a height adjusting mechanism for adjusting the height of the column member up and down, and An arm member extending from the upper portion of the column member, an arm member including a plurality of bent portions that can be bent in the horizontal direction in the middle thereof, and a holding portion provided at a tip of the arm member,
An assisting lift device comprising a pair of holding members configured to be openable and closable with a pair of holding pieces that are placed under both sides of a person and support the body.

The base member has no moving means, and may be fixedly disposed at a certain place, for example, near a bed, a toilet, or a bathtub. , Can be equipped with casters,
With such a configuration, it can be conveniently used for moving from a bed to a toilet or a bathtub. In addition, if an appropriate prime mover, for example, one equipped with an electric motor or the like is used as the moving means, the labor can be further reduced for the caregiver.

The height-adjustable column member is not limited to a specific structure as long as the height can be adjusted. It can be configured using various existing technologies. For example, such a height-adjustable column member can be composed of an outer pipe that is erected and fixed at the center of the base member, and an inner pipe that is housed therein so as to be able to move up and down.

Needless to say, the height adjusting mechanism for adjusting the height of the column member is not limited to a specific configuration as long as the mechanism can adjust the height. This is, for example,
A screw member rotatably provided upright from the base member inside the inner pipe, a nut member screwed to the screw member, and a nut member fixed to a lower end portion of the inner pipe; If necessary, it can be constituted by a rotation driving device which applies a rotational force to rotate the rotation forward or backward. It goes without saying that a suitable electric motor or the like can be adopted as the rotation drive device.

The nut member or the inner pipe may be provided with restricting means for restricting the movement in the rotation direction while allowing the movement in the elevating direction. However, this restriction means is not necessarily required.
This is because, when the care receiver is holding the care receiver, the rotation of the care receiver is restricted by the presence of the care receiver, so that no inconvenience occurs. On the other hand, when the restricting means is provided, if the base of the arm member is simply fixed to the upper end of the inner pipe, the rotation of the holding portion about the inner pipe cannot be performed. Needs to be rotatably mounted on the upper end of the inner pipe.

It is suitable that the lower end of the screw member is rotatably mounted on the base member via a thrust bearing or the like. Further, the rotation drive device,
The configuration may be such that an electric motor or the like is used so that a rotational driving force can be transmitted to the screw member via existing rotation transmitting means such as a belt mechanism or a gear mechanism.

The arm member extends horizontally from the upper portion of the column member, for example, from the uppermost end to the holding portion, or extends slightly horizontally from the uppermost end, and then slightly hangs down. It can be configured to extend horizontally to the holding portion. This arm member needs to have a sufficient strength because of the weight of the person. It is preferable that each of the bent portions is connected with a pin to form a hinge and can be freely bent in the horizontal direction.

The pair of holding portions of the holding portion are configured to be substantially symmetrical to each other, and their bases are pin-connected to the ends of the arm members, respectively, and are attached to be openable and closable. In addition, both holding pieces of the holding portion are each composed of a high-strength core material and a resilient member for exteriorizing the core material, and the front and rear upper surfaces of the portions where the armpits of the holding pieces are mounted are the portions of the portion where the armpits are mounted. It is preferable to raise the height of the armpit so as to be higher than the upper surface, and to further increase the thickness before and after the part where the armpit is placed than that of the part where the armpit is placed.

Therefore, according to the assisting lift device of the present invention, the caregiver's labor can be reduced, and the cared person can be easily and safely started up in a state where the clothes can be changed.

For example, when the care receiver is raised from the bed to use the toilet, first, the assisting lift device of the present invention is brought close to the bed and positioned toward the bed, and Adjust the height to the lowest level. Further, the arm member is folded at a bent portion, and the holding portion is retracted toward the column member.

In this state, the care receiver is raised to face the assistance lift device, the arm member is extended at the bent portion, and the holding pieces of the holding portion are placed under the care receiver's armpits. The care receiver is held in the holding section. At this time, by adjusting the opening degree of both holding pieces in advance according to the size of the cared person's chest as needed, the insertion of the both holding pieces into the armpit can be performed smoothly. . Thereafter, the height adjustment mechanism is operated, and the height of the column member is adjusted to be as high as necessary.Since the holding portion rises with this, the cared person is lifted up in the upper body, It naturally stands up from the bed.

Therefore, the caregiver can start the care receiver in the standing state without much labor and can maintain this state. Therefore, an unnecessary burden is not put on the caregiver, and problems such as occurrence of back pain can be solved. Then, when the care receiver is raised in an upright state, there is no obstacle around the waist, unlike when the person is seated on a seat, so that the attachment / detachment of the clothing becomes extremely easy. Therefore, the caregiver can easily perform the necessary attachment and detachment of the clothes for the care receiver in this state. In such a case, the care receiver is not forced to take an unreasonable posture, so that the burden is eliminated.

Then, if necessary, the holding portion is rotated about the column member, and the cared person is moved in such a manner. For example, the movable toilet placed on the side of the assisting lift device When the height adjustment mechanism is operated and lowered, the holding part lowers its height, and the care receiver naturally lowers its posture and sits on the toilet seat of the toilet. Will be able to do it.

The caregiver can change the posture of the care receiver without any special effort, and even after sitting on the toilet seat, the care receiver can hold the body under the armpits by holding the body. , It is possible to maintain a stable posture.

After defecation, if necessary measures are taken, the height adjusting mechanism is operated, and the column member is adjusted to be higher, the holding portion is raised, and the care receiver is raised to a standing state. This is as described above. Thereafter, the user can take necessary measures and easily put on clothes.

Next, if the holding portion is rotated in the reverse direction about the pillar portion and is rotated toward the bed, the care receiver is placed in a state where the bed is positioned behind and stands, and the height adjusting mechanism is further provided. If it is operated and the holding part is moved down, the posture can be changed to a state of sitting on the bed naturally. After that, the care receiver's feet may be placed on the bed and laid down.

In the above, the case of using a toilet has been described as an example. However, the present invention can be similarly used when taking a bath or simply changing clothes.

In the above case, the exterior of the holding pieces is made of an elastic member, so that the armpit of the cared person is softly supported, and the operation is comfortably supported. In addition, since the front and rear portions of the armpits of the holding pieces are raised and thickened, the armpits of the cared person can be safely prevented from falling off the holding pieces.
