The structure of the present invention for solving the above problems consists of a horizontal member that is wide enough to fit under both armpits of a person and is disposed substantially parallel to the horizontal member, and a horizontal member that is angled forwardly with respect to the horizontal member. The main body of the assisting device, which is made up of a gate-shaped member formed in a substantially square shape from the front by connecting the upper ends of the raised upright members with an upper horizontal rod, and a sling material removably stretched from the horizontal member, is vertically connected. The columnar body is rotatably attached to the lower part of the columnar body which is extendable and retractable in the direction, and the upper part of the columnar body is attached to a trolley having a planar shape that is slightly larger or approximately the same size as the outer contour of the assisting device main body when viewed from a plane. By mounting this trolley so that it can run along a guide laid on the ceiling, etc., the movement of the center of gravity due to the posture of the human body supported on the assisting device main body can be kept within the approximately planar outline of the trolley. It is characterized by the following.

[Effect]

The parallel horizontal members of the assisting device body, which are inserted under both armpits of a person with a disability, support the person by holding the person with both arms from the front or back.

In this way, the main body of the assisting device that supports the disabled person can be raised and lowered by the expansion and contraction of the columnar body to which it is attached, and the cart to which the columnar body is attached can travel and the main body of the assisting device can be rotated. It allows you to move and change direction in the horizontal plane.

The trolley has a planar shape and size commensurate with the planar outline of the assisting device main body so that it is stable even if the center of gravity of the object supported by the main body shifts due to the posture of the assisting device main body. have.

Figure 4a is a front view showing an example of movement of the center of gravity in the device of the present invention, Figure 4b is a side view, and Figure 5 is a perspective view of the device of the present invention shown in Figure 3 applied to a toilet. .

In Fig. 1, 1 and 2 are two horizontal members disposed approximately parallel to each other in a horizontal direction.
The distance between them is adjusted so that they fit under both armpits of a person.

Reference numeral 3 denotes a gate-shaped member which has a substantially square shape in front and is raised from the middle of the horizontal members 1 and 2, and the upper part of this member 3 is located at the front of the horizontal members 1 and 2 (left side in the figure). It is sloped so that it is located approximately in the center of the area.

Reference numeral 4 designates a mounting seat for a connecting member attached to the center of the upper horizontal rod 3a of the gate-shaped member 3. In addition, 3b, 3c
are the left and right rising rods of the gate-shaped member.

Here, the reason why the gate-shaped member 3 is provided at an angle is that there is room for the center of gravity to move on the horizontal members 1 and 2, that is, the supporting position of the disabled person whose armpits are supported by the horizontal members 1 and 2 is As in the case where there is a slight difference between
This is to be able to cope with the case where the position of the center of gravity changes.

From this meaning, the above-mentioned horizontal members 1 and 2 and the gate-shaped member 3
This means that in addition to the type in which separate members are joined together as in the example of FIG. 1, a type in which pipe-shaped members are bent as shown in FIGS. 2a to 2c may also be used. In FIGS. 2a to 2c, the same reference numerals as in FIG. 1 indicate the same parts.

The framework of the assisting device main body is formed by the members 1 to 4 above, and the horizontal members 1 and 2 include, for example, a third
As shown in the figure, a backrest-shaped sling material Bsl, a seat sling Ssl, a leg sling Lsl, etc. can be selected as appropriate depending on the condition of the person to be assisted and can be detachably attached. The above-mentioned slings Ssl and Lsl are sheet-shaped or belt-shaped, but there is no problem even if the seat surface or support surface is plate-shaped, for example, like the seat of a swing.

Further, the front sides of the horizontal members 1 and 2 are covered with cushion materials 5 and 6, and the above-mentioned members form an example of the assisting device main body AS in the device of the present invention.

This assisting device main body AS is attached with a structure as shown in FIG. 3, and constitutes an example of the device of the present invention.

In Fig. 3, reference numeral 7 denotes a trolley mounted on a guide rail 8 attached to the ceiling or the like so that it can run. 1, 2 front width, and
The size corresponds to the side width and the amount of movement of the center of gravity due to the posture of the human body supported by this main body AS, and here, it is matched to a planar rectangular shape that is slightly larger than the planar outline of the main body AS.

For example, as shown in FIGS. 4a and 4b, in the assisting device main body AS supported by the trolley 7, the position of the center of gravity of the person with a disability, etc., may vary depending on the posture of the supported person, etc. , or it is not constant with respect to the left and right, in other words, even if it moves or shifts slightly, the assist device main body AS attached to this trolley 7 will not sway, and the lifting and lowering of the main body AS and the trolley 7 This is to facilitate the movement of people.

Reference numeral 9 denotes a columnar body, for example, a fluid pressure cylinder, which is attached downward to the lower surface of the truck 7. This columnar body is extendable and retractable because its piston rod 9a can freely move in and out of the cylinder 9.

With the coupling spring inserted between AS mounting seat 4,
This allows the assisting device main body AS to pivot relative to the rod 9a.

In Fig. 4, gs is the amount by which the center of gravity has moved due to the posture of the person being supported, and GS is the range in which the center of gravity remains stable even if the center of gravity moves.

Note that the cart 7 has its wheels 7a on the guide rail 8.
Although the vehicle is mounted so that it can travel via a motor, the vehicle may be driven by a driving force such as a motor. The same applies to the turning force in the coupling 10.

Further, in the above example, the driving pressure generation source of the columnar hydraulic cylinder 9 may be mounted on the truck 7. Further, operating units for each of these drive sources are provided on the assisting device main body AS so that the person can operate them, or provided for use by a caregiver via an extension cord or the like.

An example of the assisting device of the present invention formed in this way supports a disabled person in a state as if he were hanging on an armchair by attaching a sling material SL as appropriate, and allows the trolley 7 to travel and rotate in the coupling 10. , and the movement of the rod 9a of the columnar cylinder 9 to assist the supported person with a disability in vertical, longitudinal, or horizontal movement.

FIG. 5 shows a case in which the above-described device of the present invention is applied to a toilet, in which a rail 8 extends from the outside to the inside of the toilet booth T.

Therefore, disabled person m with impaired lower limb function who is riding in wheelchair C operates wheelchair C so that his armpits correspond to the cushioning materials 5 and 6 of lateral members 1 and 2 of the assisting device main body AS. Positioned in

This person m raises both his arms and places the horizontal members 1 and 2 over the cushion materials 5 and 6 under both armpits, and then lifts the sling material Lsl that is applied to the lower side of the thigh.
Hook f on the tip of the horizontal member 2. Note that the rear end side of this sling material Lsl is attached to the horizontal member 1 in advance.

In this state, the cylinder 9 is operated and the rod 9
When a is moved backwards (upwards), disabled person m can be lifted up with both armpits and thighs supported from below, allowing him to be transferred from wheelchair C to the assistive device AS. . Therefore, the main AS
Change the direction of the body by 90 degrees counterclockwise, move the trolley 7 to the side of the toilet bowl B in the toilet booth T, and stop the running of the trolley 7 when your body is directly above the toilet seat S. Make preparations for this, move the rod 9a of the cylinder 9 to the descending side, and have the person sit on the toilet seat S. When the person sits on the toilet seat S, the advancement of the rod 9a is stopped and the person finishes his business.

After finishing the job, the patient can return to the wheelchair C by performing the opposite operation to the above, and transfer from the assist device AS to the wheelchair C.

The above example is an application example of the device of the present invention for toileting, but the device of the present invention can also be used in various other situations such as getting in and out of a bathtub from a wheelchair or bed, or transferring between a bed and a wheelchair. Of course it is possible.

〔Effect of the invention〕

The device of the present invention lifts and supports both armpits of a disabled person with the aid body, and supplements this support with the necessary sling material, so it is as if the disabled person is being held in the caregiver's arms. It can be supported in various ways.

Furthermore, the main body of this assistive device may sway even if the position of the center of gravity of the person supported by it changes due to the support position of the person with a disability being supported by it moving back and forth or changing the posture. In order to avoid this, the robot is attached to a trolley with a planar size commensurate with the range in which the center of gravity is allowed to move, via a support member that can be raised and lowered. This has the effect of causing almost no shaking.

Since the present invention is as described above, it is extremely useful as an assistance device for persons with disabilities.
