Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile care lift capable of lifting and lowering a patient in a room having a soft floor such as a Japanese-style room without scratching the floor.

[0002]

2. Description of the Related Art In patients who have been bedridden for a long time in beds for home use, hospital beds, seriously ill patients, and elderly people, for example, when the patient holds a body in a wheelchair or a toilet bowl near the bed, caregiver assistance is required. Is often required. That is, the caregiver had to move the patient to the side of the floor and transfer the patient to a wheelchair or the like while supporting the patient's body. At that time, depending on the patient's condition, the caregiver may have to carry the patient on his back, and the caregiver was forced to make a great deal of effort. Therefore, various lift devices for dynamically lifting a patient have been proposed. As such a lift device, for example, a fixed type or a movable type can be mentioned. The former is fixedly installed on the floor of the room and is satisfactory in terms of strength, but once installed, the bed installation location is uniquely determined, and there is no freedom of installation. On the other hand, the latter can be used regardless of the position of the bed and can be freely moved to be transferred to a wheelchair or the like, and is therefore excellent in mobility.

[0003]

However, since beds for home use are often arranged in a Japanese-style room, the casters sink into the tatami when moving, making it very difficult to use and lacking stability, and the tatami is scratched. It will also happen. From this background, it is an object of the present invention to provide a mobile care lift capable of lifting and lowering a patient without scratching the floor even in a soft floor such as a Japanese-style room.

[0004]

In order to solve the above-mentioned problems, the present invention comprises a trolley, a column vertically installed on the trolley, and a lifting arm for lifting a patient, which is movably connected to the column. A mobile nursing lift, wherein at least a disk-shaped leg base having a convex bottom surface on one end side is deflected by a predetermined angle with respect to a vertical line with respect to the floor surface and is rotatably mounted on the carriage. Characterize.

[0005]

When the patient is hoisted, the hoisting arm is lowered to bring the tip of the hoisting arm close to the upper side of the patient. For example, the end of the hoisting sheet on which the patient's body is placed is hung on the hoisting means, and the hoisting arm is raised. Can be lifted. Then, the caregiver supports the body of the patient together with the lifting sheet and moves the cart. When the bogie is pulled in so as to change the direction when moving, tangential stress is generated at the ground contact point on the bottom surface of the disc-shaped leg base, and a rotational force about the support axis of the disc-shaped leg base is given, so that the disc-shaped leg base moves. As a result, the trolley rotates about the support shaft, and as a result, the trolley can be easily turned around and can be moved to a desired place. Since the bottom surface of the disk-shaped leg base is a gentle convex surface with a large radius of curvature, the contact area with the floor surface is sufficient, and it is possible to prevent local loads from being applied. The disc-shaped leg base does not sink to the floor surface even when moving, and it is possible to move stably.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a mobile care lift according to the present invention will be described below with reference to the accompanying drawings, with reference to an embodiment. FIG. 1 shows a mobile care lift 1. This mobile care lift 1 includes a trolley 2 and columns 3 standing on the trolley 2.
And a lifting arm 4 for lifting a patient, which is movably connected to the support column 3, a lifting means 5 at the tip of the lifting arm 4, and a lifting sheet 6 adapted to be hung on the lifting means 5, An electric actuator 7 for expanding and contracting is connected between the suspension arms 4 to drive the suspension arms 4 up and down. The trolley 2 has a shape in which the front end side is low and the rear end side is high.
A disk-shaped leg base 8 having a convex bottom surface is mounted on the front end side, while a normal caster 9 is mounted on the rear end side.

The column 3 is erected in the vicinity of the rear end of the carriage 2, and the lifting arm 4 and the column 3 are connected by an electric actuator 7. When the electric actuator 7 is activated, the entire lifting arm 4 becomes the column 3. It is configured to rotate around the tip and rise and fall.

At the tip of the lifting arm 4, a hanger-shaped lifting means 5 having an intermediate portion rotatably attached is provided. The lifting means 5 is provided with hook members 10a and 10b at the ends of both arms in the shape of a hanger so that a lifting sheet 6 for lifting a patient can be hung (see FIG. 2). The lifting sheet 6 is made of, for example, a synthetic fiber cloth, and has hook members 10a and 10b.
The patient is hung by hanging the end of the lifting sheet 6 on.

The electric actuator 7 has a well-known structure, and although not shown, a screw shaft is rotated by a motor, and a retractable shaft is moved forward and backward on the screw shaft so that the lifting arm 4 is undulated and lifted. The means 5 has a function of lifting the patient from the floor (not shown) or lowering the patient to the floor (not shown).

As shown in FIG. 3, the disc-shaped leg base portion 8 is rotatably attached to the lower portion near the front end portion of the carriage 2 and has a bottom surface 11 having a large spherical shape with a radius of curvature (640 mm). A flexible member (synthetic resin or the like) having appropriate elasticity can be applied, and the disc metal fitting 12 is attached to the upper surface. As shown in FIGS. 3 and 4, the disc-shaped leg base 8 deflects 10 degrees in the tread direction (X direction) of the carriage 2 and 5 degrees in the wheel base direction (Y direction) with respect to the vertical line with respect to the floor surface. And is mounted (see FIG. 1). As a result, the ground contact point P with the floor surface is set at a position separated from the rotation axis by a predetermined distance outward in the tread direction (see FIG. 5).

The mobile care lift according to the present invention is constructed as described above, and its operation will be described below. When the patient is lifted, the patient's body is wrapped with the lifting sheet 6, and the electric actuator 7 is used.
Is operated to lower the lifting arm 4 to bring the lifting means 5 at the tip of the lifting arm 4 close to above the patient. Then
The end of the lifting sheet 6 that wraps around the patient's body can be hung on the lifting means 5, and the electric actuator 7 can be actuated to lift and lift the lifting arm 4.

Then, the caregiver supports the body of the patient together with the lifting sheet 6 and moves the carriage 2. When the carriage 2 is pulled in so as to change the direction when moving, a stress is generated at the ground contact point P on the bottom surface 11 of the disc-shaped leg base 8, and a rotational force about the rotation axis of the disc-shaped leg base 8 is applied, The disc-shaped leg base 8 rotates about a rotation axis, and as a result, the carriage 2
Can be easily turned around and moved to a desired place. The bottom surface 11 of the disk-shaped leg base 8
Since it is a spherical surface with a large radius of curvature, the contact area with the floor surface is sufficient, it prevents local load from being applied, does not scratch the floor surface, and it does not sink while moving. Rather, it can provide driving stability.

In this way, the electric actuator 7 is operated to lift the patient, and the disk-shaped leg base 8 at the front of the carriage 2 stabilizes the running even when the floor surface is tatami.
Although it is difficult to go straight, it can be freely moved to a desired place and can be transferred to a wheelchair, a toilet container or the like, so that the caregiver's labor can be significantly reduced.

[0014]

As described above, according to the present invention,
Even in a room with a soft floor, the patient can be lifted and lowered without scratching the floor, and the caregiver's labor can be greatly reduced.
