Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elderly person with weak legs, a physically handicapped person, etc., from a wheelchair to a bed, or for mutual transfer between a wheelchair and a toilet seat, a shower chair, a sofa, a car seat, etc. The present invention relates to an applied human body transfer device.

[0002]

2. Description of the Related Art Conventionally, there have been various inventions related to this type of transfer device.
Many have been devised, but most of them have a structure in which a part of a transfer device such as a belt is passed over the buttocks or crotch of a person who is sitting on a chair or bed to lift the person. Is. However, the caregiver must lift the person to be transferred one by one to lift the buttocks and crotch from the chair or bed, and the same troubles are taken when lowering the object to be transferred. It is especially inconvenient when moving to a toilet seat or the like. Further, the instability caused by the lifting operation is also a problem.

Therefore, with the intention of solving this problem, for example, a support is tilted upright on a turntable,
A device provided with a receiving plate at its tip (Japanese Patent Laid-Open No. 1958/1989)
No. 57), and a pillar is erected on a pedestal with casters, a tiltable branch pillar is taken out from a position corresponding to approximately the knee height of the pillar, and a body holder is provided at the tip of the branch pillar. (See Japanese Patent Laid-Open No. 3-218755) has been proposed.

However, in both the former and the latter, the pillars and branch posts are erected by stepping on the pedals, and since the movement is structurally simple, the upper plate of the person to be transferred should be placed on the back plate and the holder. It is not easy to stand up and tilt the main pillar and branch pillars slowly and quietly in a standing state.Therefore, it may happen that the main pillar and branch pillars are suddenly raised and tilted by pushing the pedal too hard. , The posture may become unstable, or the line-of-sight angle of the transferred person may change suddenly, which may cause fear. Furthermore, this point requires that when the transferred person is lowered from the device to the target transferred object, the operation must be performed in consideration of the momentum of the descending of the weight center of gravity of the transferred person. Considering that he is backwards, his anxiety is exacerbated. Therefore, use of the device may be refused.

In particular, when the caregiver is a weak woman or the elderly is difficult to operate, and when the upper half of the person to be transferred is placed on the receiving plate or holding tool, the inclination angle,
There is also a problem that the height and position cannot be changed, which is inconvenient.

Therefore, in order to solve the above problem, a main pillar is erected on a pedestal having casters, and a horizontal frame, on which a support plate of the body is tiltably supported toward the tip, is screwed to the main pillar. It is proposed by the applicant of the present invention that the tilt angle adjusting mechanism, which is a combination of a gear transmission mechanism and a winding transmission mechanism, is mounted on the horizontal frame so that the receiving plate can be tilted by a mechanism. ing.

According to the above apparatus, the inclination angle and height of the receiving plate for supporting the upper half of the body can be adjusted appropriately and gently in an analog manner over a wide range. It is effective in reducing feelings and fears, but it still has the following points to be improved.

[0008]

That is, at least two caregivers are required for desorption, and in addition to using the existing weight-holding belt, which is a heavy labor, the above-mentioned device is designed to hold the body stably. The structure of the board is a problem. That is, in the above-mentioned device, the receiving plate has a shape that only exposes the upper body, that is, the front surface of the chest.

Therefore, after the person to be transferred is bent forward and the chest is placed on the backing plate, the backing plate is raised to an appropriate height,
When the transferred person is lifted from a sitting posture and transferred onto the device in a mid-waist posture, a sick person who needs a caregiver,
Since the will of a healthy person does not work against tilting and raising of the backing plate, it is unavoidable that the backing plate is easily displaced to the side or downward, and stable holding cannot be obtained. Therefore, local or unbalanced force is applied to the transferred person, causing physical pain or feeling of mental anxiety. This drawback is more remarkable in the above-mentioned prior art.

By the way, in a facility or the like having a physically handicapped person who particularly needs a human body transfer device, the degree of disability of the resident varies. There are people from people with weakened legs to people who have no physical freedom and cannot even care for caregivers. However, in the prior art, apart from the intention of the inventor, in reality, the physically handicapped person who can actually and voluntarily move the object of the human body transfer device to some extent-that is, a certain muscular strength and a sense of balance for the transfer work. , Limited to persons with physical disabilities who can take voluntary follow-up behavior using flexibility. For example, in the case of a person who cannot bend his / her waist while sitting on a wheelchair in a natural manner, a person who has no limb muscular strength, and a person who has a particularly good physique, it is difficult for the conventional invention to handle it. However, the main cause of back pain and the like in the caregiver is the work of caring for the physically handicapped who has such severe or special conditions. Therefore, in the prior art, the practical significance of providing the device, in other words, the "industrial utility value" is halved. This is because, as we have already seen, there is no freedom, mediocrity, or binding power in the part that receives the human body. In the first place, the physique is different for each person, and in addition to that, there are various types of disability, which makes sense. When the transferred person is a healthy person, the transferred person unconsciously takes a voluntary following action by using a certain amount of muscle strength, sense of balance, and flexibility. What is necessary for a human body transfer device that handles physically handicapped persons who do not have this kind of ability is that it has both the degree of freedom and the binding force to stably contain it without depending on the ability of the transferred person. It is a function.

The present invention has been made in view of the above-mentioned problems of the above-mentioned prior art. It is possible to stably hold the chest on a tilting support plate and to voluntarily follow the transfer work. Safe to transfer, including those who do not work
It is an object of the present invention to provide a human body transfer device that can be easily carried out and can eliminate the physical pain, anxiety, and fear of the transferred person.

[0012]

In order to achieve the above object, a human body transfer apparatus of the present invention comprises a main pillar standing on a pedestal having casters, and the main pillar is provided with a body receiving plate to the tip. In a human body transfer device comprising a horizontal frame rotatably rotatably supported by a vertical feed mechanism, the horizontal frame is provided with an inclination angle adjusting mechanism so that the receiving plate can be tilted. , A substantially circular shape in plan view, and a substrate and a plurality of auxiliary plates are pivotally formed so as to be openable and closable in the radial direction, and a chest of a human body can be held on the receiving plate in accordance with its physique. As described above, a fastener such as a string or a band is attached to the opening.

[0013]

For example, when transferring from a bed to a wheelchair or from a wheelchair to a toilet seat, the caregiver operates according to the following procedure.

(A) The apparatus is brought close to the seated occupant in front of him and his foot is placed on the pedestal.

(B) After the horizontal frame is lowered by the elevating and feeding mechanism and held at an appropriate height, the backing plate is adjusted to an appropriate angle by the tilt adjusting mechanism.

(C) The apparatus is brought close to the person to be transferred so that the chest of the person to be transferred can be fitted into the opened opening.

(D) The fastener is tightened in the direction to close the opening of the receiving plate to hold the chest. As a result, the chest will not shift to the side of the backing plate, it will be in the same state as being held by the caregiver, and both upper edges of the backing plate will be pressed against the armpit,
The upper arm serves as a stopper to prevent downward slipping, so that the transferred person is held stable and does not feel anxiety or fear. Furthermore, since most of the weight is supported by the holding force, the force exerted on the upper arm is small, and there is no physical pain.

(E) Further, if the protruding handles on both the left and right sides of the horizontal frame are held by both hands, the sense of security of the transferred person is further increased. Of course, in the case of a person with a handed hand, even if he / she cannot hold the handle in particular, it does not hinder a stable transfer.

(F) The elevating and lowering feed mechanism is operated to raise the horizontal frame and raise the receiving plate to an appropriate height. As a result, the person to be transferred is lifted from the sitting posture and safely transfers to the device in the middle-waist posture.

(G) Next, the pedestal is pulled toward you, turned and moved to the side of the object to be transferred, and thereafter, the transfer is completed by the operation reverse to the above.
