However, in the traveling-type nursing lift, the casters in front of the lift have to be sunk under the bed, and there is a restriction on the height. Absent. for that reason,
The traveling property is not good when moving by hanging an elderly person or the like, particularly when climbing over a step. In addition, Japanese houses inherently have many steps and often become a major obstacle when moving, which further impairs traveling performance. The present invention has been proposed to improve such inconvenience, and when suspending and moving an elderly person or the like, the suspension means is provided to a larger one of the wheels to enhance a sense of stability, and the indoor steps and the like are improved. It is an object of the present invention to provide a column-rotation type traveling care lift that facilitates overcoming and improves traveling performance.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, one embodiment of a rotating support type traveling care lift according to the present invention will be described with reference to the accompanying drawings. FIG. 1 shows an electric column rotating type nursing care lift 1.
A bogie 2 for lifting and transferring an elderly person or the like between a bed (not shown) and facilities other than the bed, a wheelchair, a stretcher, a toilet, etc., and configured to be inserted from the side of the bed to the bottom below. And a column 3 erected on the carriage 2 and a base end portion rotatably mounted on the upper end side of the column 3 and a linear motion shaft 4a constituting a linear drive mechanism 4 connected to an intermediate portion. The linear motion drive mechanism 4 drives the linear motion shaft 4a to expand and contract, thereby raising and lowering the distal end portion. At the end of the boom 5, a hanger 6 for lifting an elderly person or the like is provided.
The carriage 2 includes a pair of base frames 9, 9 each having a first wheel 7 on one end side and a second wheel 8 having a larger diameter than the first wheel 7 on the other end side, and these base frames 9. And a horizontal frame 10 connected near the other end of the base frame 9. Then, a column mounting portion 11 attached to the horizontal frame 10 is provided, and the column 3 is rotatably held on the column mounting portion 11. With this structure, when the elderly person is lifted and moved, the column 3 is rotated to bring the hanger 6 at the tip of the boom 5 to the other end of the base frame 9.

[0006] The base frames 9, 9 are provided with first wheels 7
The distance at one end where the second wheel 8 is attached is set to be larger than the distance at the other end where the second wheel 8 is attached, and the first and second wheels 7 are provided at both ends. , 8 are provided. These wheel receiving members 12 and 13 support the bogie 2 in a horizontal state by setting the flip-up height according to the vehicle diameter of the first and second wheels 7 and 8 as a side flip-up shape.

The column 3 is fixed to the column mounting portion 11 at an angle (about 75 °). In this case, as shown in the drawing, the upper side of the column 3 is directed to the side where the second wheels 8 are mounted on the base frames 9 and 9. At the place where the boom 5 attached to the top side of the column 3 is attached, a care lift 1 is provided.
A handle 14 for pushing and moving the. In this case, the handle 14 is a substantially U-shaped pipe frame, and is attached so as to sandwich the boom 5 from both sides at the attachment point, while hanging down at a predetermined angle with respect to the support 3. The lower end frame side is fixed to the column 3 via a mounting frame 15. A motor casing 16 containing a motor (not shown) of the linear drive mechanism 4 is attached to an intermediate portion of the column 3, and a distal end of a linear shaft 4 a protruding from the motor casing 16 is attached to the boom 5. I'm wearing

The boom 5 has an arcuate shape in which the side close to the distal end is curved. Further, the hanger 6 attached to the distal end side has a suspension arm 17 having an intermediate portion attached to the distal end of the boom 5 so as to hold both end sides at the same height position, for example, urethane foam molding, It consists of a plurality of arc-shaped steel cores (not shown) of a specific radius of curvature covered by a soft outer member made of urethane foam-filled vinyl leather. It has hook members 18 and 19 for suspending the hanger.

In the nursing lift 1 having such a configuration, the column mounting portion 11 mounted on the base frame 9 for rotatably supporting the column 3 is attached to the horizontal frame 10 between the pair of base frames 9, 9. A fixed support (not shown) has a rotation support base 11a that is rotatably mounted around the central shaft portion 20. In this case, the column 3 is attached near the periphery of the rotation support base 11a. The details of the rotation support structure between the base and the rotation support base 11a are not shown and will not be described, but a known structure can be adopted.

The supporting column rotating type traveling care lift 1 according to the present invention is configured as described above. Next, the operation thereof will be described. When moving the elderly or the like from the bed B to a wheelchair, a toilet, a bathroom, or the like, the caregiver holds the handle 14 of the care lift 1 and adjusts the inclination direction of the support 3 to the side of the bogie 2 where the second wheel 8 is attached to the base frame 9. Toward
With the hanger 6 at the end of the boom 5 raised above the first wheel 7 having the smaller diameter of the base frame 9, the first wheel 7 having the smaller diameter of the base frame 9 is placed below the bottom of the bed B. Push in front. Then, the linear motion drive mechanism 4 is operated to move the boom 5, and the old man or the like is put on the hanger S hanging on the hook members 18, 19 of the hanger 6.
The nursing care lift 1 can be lifted and pulled out again from under the bottom of the bed B (see FIG. 2).

[0011] Here, the caregiver holds the handle 14 and rotates the column 3 so that the inclination direction of the column 3 is directed to the side of the bogie 2 where the first wheel 7 is mounted on the base frame 9. As a result, the hanger 6 at the tip of the boom 5 on which the elderly or the like is
It can be brought upward on the wheel 8 side (see FIG. 3). In this state, the caregiver can hold the handle 14 and push it in to carry the elderly or the like to the destination. The load applied to the second wheel 8 side of the base frame 9 increases. For example, when the vehicle runs across a sill from a tatami mat, the tatami mat sinks due to its weight and the first wheel 7 Since the second wheel 8 having a larger diameter than that of the first embodiment straddles the threshold, the vehicle can easily get over the sill and the traveling is not significantly hindered.

[0012]

As described above, according to the present invention, when the elderly person is lifted from the bed and the dolly is sunk under the bed, the smaller diameter first wheel side is pushed in, and the elderly person is hung on the hanger at the end of the boom. In this state, hold the handle so that the direction of inclination of the column is directed toward the first wheel mounting side of the base frame of the bogie, that is, the hanger at the end of the boom that suspends the elderly etc. Because it is brought to the upper side of the two wheels, even when the load is applied to the second wheel side having a large diameter, when moving in the room, it is possible to easily get over some steps and the traveling is significantly hindered. It is easy to use even in Japanese houses with many steps.
