Abstract

PROBLEM TO BE SOLVED: To provide a nursing lifting device that has an arm part composed so as to reduce deviation of seating position when a user is moved from a bed to a wheelchair or the like.SOLUTION: The lifting device is structured with: an arm part in which the turning proximal end side of a first link arm and a second link arm are pivotally supported on a prop and in which the turning distal end side of the first link arm and the second link arm are pivotally supported on a third link arm; extending/contracting means which is interposed in the prop and the arm part; and a hanger part which is pivotally supported on the third link arm. As a result, when the hanger part is elevated, the first link arm as well as the second link arm turns. However, during the rolling of the shaft member of the second link arm from the right end to the left end in a slot, the third link arm makes no turns. When the shaft member reaches the left end, the force of the extending/contracting means makes the shaft member on the turning distal end side of the first link arm as a fulcrum, making the turning distal end side of the third link arm turn, thereby reducing deviation in the forward/backward direction of the hanger part during the elevating/lowering.SELECTED DRAWING: Figure 9

Description

  The present invention relates to a care lift device used for moving a user from a bed or the like to a wheelchair or the like.

  Conventionally, to reduce physical burdens such as low back pain when a person with a physical disability or an elderly person who needs care (hereinafter referred to as a user) is moved from a bed to a wheelchair. A care lift device for transferring a user using a sling sheet was used.

Various types of care lift devices are used depending on the use environment.
For example, a care lift device is installed on the bedside, a house is renovated and the arm is fixed to the ceiling or wall surface, and a floor traveling type equipped with wheels.
As for the lifting mechanism of the hanger, there are a mechanism in which the arm part pivots around the column to lift the hanger that suspends the user, and a mechanism that hangs the hanger from the upper frame with a wire or a rope.
Above all, as an advantage of the arm rotation type lifting mechanism, the entire product can be configured more compactly than the hanging arm mechanism, so there is no need to consider the floor plan of the room and the entire product is inexpensive. There are benefits that can be provided.
However, as shown in FIG. 10, since the arm pivoting type lifting mechanism of the conventional nursing lift device performs an arc motion, when the user is moved from a bed or the like to a place with a different height such as a wheelchair, The position where the user is seated differs depending on the moving position, and each time the assistant makes fine adjustments to the seating position of the user, it takes time for assistance. This has given the physical burden concerning a user's waist | hip | lumbar, a buttocks, etc. by changing a seating position not only a helper but many times.

  In order to solve this problem, the following nursing lift device has been proposed.

The care lifting device of Patent Document 1 will be described.
As shown in FIG. 10 of the prior art document, this care lift device is configured such that the lift arm is a two-joint type arm, and a shaft is provided between the distal end side lift arm and the proximal end side lift arm during the turning operation. The tip lift arm can be folded around the axis P2 with respect to the proximal end lift arm and moved up and down while maintaining a horizontal posture so that the hip can be folded around the core P3. .

Japanese Patent No. 3879875

However, since the lift device for nursing care described in Patent Document 1 moves up and down while maintaining a horizontal posture, the shift between the front and rear can be reduced at the lowest and highest positions. In the middle position between the lowest position and the highest position), the tip of the lift arm protrudes and the displacement is large.
In addition, it is thought that the backlash between parts increases because the number of joint members increases due to the construction of the two-joint type arm, and when the user is suspended by a sling seat, the swing becomes large and the user feels uncomfortable. It has become something that gives.
Moreover, it is considered that the cost increases due to the increase in the number of parts due to the increase in the number of joint members.

  Therefore, the problem to be solved by the present invention is to provide a care lift device in which an arm portion is configured so that a displacement of a sitting position is reduced when a user is transferred from a bed or the like to a wheelchair or the like.

The nursing lift device according to the present invention is configured such that the rotation base end sides of the first link arm and the second link arm are pivotally attached to the support column by the shaft member, and the rotation tip ends of the first link arm and the second link arm An arm portion constructed by pivotally attaching the side to a third link arm with a shaft member, telescopic means interposed between the support column and the arm portion, and a hanger portion for suspending a user with a sling seat In the lift device for nursing care that is configured to be pivotally attached to the link arm, the first link arm is rotated upward and the second link arm is also rotated upward when the telescopic means is extended when it is raised. When the shaft member of the second link arm rolls from the right end portion to the left end portion, a force of the expansion / contraction means is applied to the third link arm. So that it is not transmitted to the shaft When the material reaches the left end, the shaft member on the rotation tip side of the first link arm is used as a fulcrum, and the shaft member on the rotation tip side of the second link arm is used as a force point. The force of the expansion / contraction means is transmitted to the three link arms so that the rotation tip side of the third link arm is pivoted upward, and when it is lowered, it is configured to perform the reverse operation when it is raised, It is characterized in that the seating position of the user can be easily adjusted by reducing the displacement in the front-rear direction of the hanger part when the hanger part is raised and lowered.
The first link arm and the second link arm of the arm portion are cross links.
Further, the hanger part is provided with a lift switch for driving the expansion / contraction means.
Furthermore, at least two strut legs are characterized in that the strut portion structure is formed so that the strut bracket is formed in a substantially inverted V shape in front view toward the base portion with the strut bracket as a base end.

The care lift device according to the present invention is configured as described above, so that when the user is transferred from a bed or the like to a wheelchair or the like, the arm portion and the hanger portion are less displaced in the front-rear direction during lifting. Therefore, since there is no worry that the assistant may mistakenly measure the user's sitting position, it is possible to reduce the trouble of finely adjusting the sitting position when the user is seated, and to reduce the burden on the assistant. it can. In addition, the user can be prevented from being physically burdened on the hips, buttocks and the like due to sitting in an unreasonable posture by shifting the seating position from an appropriate position.
And since the arm part can be made small and compact by making the 1st link arm and the 2nd link arm which comprise an arm part into a cross link mechanism, the workability | operativity of a caregiver can be improved. Further, when the user is hung by the sling seat, the arm portion can be moved away from the vicinity of the user's face, so that the feeling of pressure can be reduced.
And by providing the hanger part in the hanger part for driving the expansion / contraction means, it is not necessary for the assistant to repeat the storing and taking out of the lifting switch as compared with the cord type lifting switch, thereby improving workability. Can do. Moreover, it is possible to prevent disconnection due to intermittent extension of wiring such as a cord. Further, when the sling sheet is not normally hung on the hook of the hanger part, it is possible to instantly recognize and cope with it, so that it is possible to reduce the risk of the user falling accidentally.
When the user is hung on the sling seat, at least two support legs constituting the support part are opened in a substantially inverted V shape with the support bracket as the base end toward the base part. However, it is possible to reduce discomfort of the user due to the lower limbs coming into contact with the structural member. In addition, it is easy for the assistant to go around the user's lower limbs, and the physical burden on the assistant can be reduced by reducing the care operation in an unreasonable posture.

The care lift device 1 includes a base portion 2 that mainly travels on a floor surface, a column portion 3 that is supported by the base portion 2, an arm portion 4 that is rotatably supported by the column portion 3, The arm 4 comprises a hanger 5 supported at the tip.

First, the base part 2 will be described.
As shown in FIG. 2 and the like, the base portion 2 is formed in a substantially H shape in plan view.
More specifically, the base end side of the base legs 22, 22 which are attached to the front end side with the front wheels 21, 21 and spaced apart from each other by a fixed distance is pivotally attached to the base bracket 23. The rear wheels 24 and 24 are attached to the opposite side of the base bracket 23 to which the base legs 22 and 22 are attached. An opening / closing pedal 25 that opens and closes the base legs 22 and 22 is attached to the center of the base bracket 23 in plan view.
Although the detailed description of the mechanism of the base portion 2 configured in this way is omitted, when the right side of the opening / closing pedal 25 is stepped on, the tip ends of the base legs 22, 22 open, and when the left side of the opening / closing pedal 25 is stepped on, the base leg 22, The front end side of 22 is closed. This is to make the leg lift wider than the width of the wheelchair so that the care lift device can be made compact and the running stability and the user can be lifted from the wheelchair.

Next, the support | pillar part 3 is demonstrated.
As shown in FIG. 3 and the like, the support column 3 includes support column legs 31 and 31 formed of two bent frames, a support column bracket 32 disposed on the upper end of the support column legs 31 and 31, and the support column. It is mainly composed of handles 33 and 33 attached to both ends of the bracket 32.
More specifically, as shown in FIG. 3, the support legs 31, 31 are fixed to both outer ends of the support brackets 32 whose base ends are formed in a substantially U shape in plan view. An end is formed in a substantially inverted V shape toward the base portion 2, and the tip is inserted into and attached to the substantially cylindrical column leg supports 26, 26 of the base portion 2.
In this embodiment, the support legs 31 and 31 are composed of two bent frames. However, in order to increase stability, the support legs 31 are configured to be supported by 4 points on the base portion 2. Alternatively, the single support leg 31 may be arbitrarily set without any problem as in the conventional lift device for nursing care.

Next, the arm part 4 will be described.
The arm portion 4 is pivotable so that the pivot base end sides of the first link arm 41 and the second link arm 42 can be pivoted in the vertical direction via the shaft members 43 and 44 respectively on the column bracket 32 of the column unit 3. I wear it. (Note that, as shown in FIG. 4 and the like, the clockwise direction in the right side view is described as upward rotation, and the counterclockwise direction is defined as downward rotation.) Then, the first link arm 41 and the second link arm 42 are rotated. The moving tip side is pivotally attached to the third link arm 47 via shaft members 45 and 46, respectively. The shaft member 45 serves as the center of rotation of the third link arm 47, and the shaft member 46 is disposed so as to roll in a long hole 42a provided on the rotation tip side of the second link arm 42.
And the hanger part 5 mentioned later is supported so that rotation is possible at one end of this 3rd link arm 47 so that it may hang down. In the first link arm 41, boss members 41b and 41b are fixed to both ends of a frame 41a bent substantially in a letter shape.
Further, the second link arm 42 and the third link arm 47 are each configured to have a substantially U-shaped frame structure, but the first link arm 41 and the second link arm 42 are substantially U-shaped as shown in this embodiment. For example, a pair of plates may be arranged to face each other.
Furthermore, in the present embodiment, the cross link (X link) mechanism in which the lines intersect when the shaft members 43 and 45 of the first link arm 41 are connected by a line and the shaft members 44 and 46 of the second link arm 42 are connected by a line. It has become.
By comprising in this way, compared with the arm part 4 comprised by the parallel link, since the 1st link arm 41 and the 2nd link arm 42 can be piled up, the structure of the arm part 4 can be made more compact. it can.

Further, an expansion / contraction means 48 for driving the first link arm 41 is interposed between the support column portion 3 and the arm portion 4.
In the present invention, an actuator is used for the expansion / contraction means 48.
A battery 49 of the lifting / lowering means 48 is disposed behind the support column 3.
The extending side (front end side) of the expansion / contraction means 48 is pivotally attached to an arm bracket 41c fixed to the first link arm 41 via a shaft member 48a so that the first link arm 41 can pivot in the vertical direction.
And the base end side of this expansion-contraction means 48 is pivotally attached to the expansion-contraction means brackets 31b, 31b fixed to the bush frame 31a fixed to the support legs 31, 31 via the shaft member 48b.
The expansion / contraction means 48 is not limited to an actuator, and may be arbitrarily set as long as it can drive the arm portion 4.

Next, the hanger part 5 will be described.
The hanger portion 5 includes a hanger 51 made of a structural material for suspending a user by a sling sheet, elevating switches 52 and 52 for driving expansion / contraction means 48 provided on the hanger 51, and the hanger 51. Hanger cover 53 formed so as to cover.
This hanger part 5 is explained in full detail using FIG. In FIG. 8, the hanger cover 53 is omitted. The hanger cover 53 is made of resin and is configured by fitting the respective covers on the male side and the female side so as to cover the hanger 51 and the elevation switches 52, 52. The shape of the hanger 51 and the elevation switches 52, 52 It is configured in accordance with.
First, the other ends of a pair of hanger sledge plates 51b and 51b which are formed symmetrically and fixed with one end overlapped are fixed to both sides of the hanger boss 51a.
And U-shaped hooks 51c, 51c,... Are fixed to the tips of the hanger sledge plates 51b, 51b.
And the stoppers 51d and 51d are pivotally attached to the hooks 51c, 51c,.
The stoppers 51d and 51d are provided for retaining the strap when the strap (suspending ring) of the sling sheet is hooked on the hooks 51c, 51c,.
The hanger 51 is pivotally attached to the third link arm 47 by a shaft member 54 so as to be rotatable.
And the raising / lowering switches 52 and 52 for driving the raising / lowering means 48 are attached further above the stoppers 51d and 51d.
Then, the stepped shaft 51e is inserted into the hanger boss 51a, and the shaft member 54 is inserted into the third link arm 47 so as to be pivotally attached, so that the hanger portion 5 can be rotated in the horizontal direction. Yes.
Although not shown in the drawings, the wiring of the elevating switches 52, 52 is routed from the inside of the third link arm 47 and through holes formed in the first link arm 41 after leaving the hanger portion 5. By being configured to be connected to the expansion / contraction means 48, the wiring is prevented from being exposed to the outside.
In this embodiment, the lift switches 52 and 52 are installed in the hanger part 5, but a lift switch may be installed in addition to the hanger part 5.
For example, it may be installed on the column bracket 32 side of the column unit 3, may be used in combination with a cord type lift switch, or may be arbitrarily set according to the use environment of the user.

The care lift device 1 configured as described above has a shape in which the support legs 31, 31 of the support column 3 are gradually opened downward, and the expansion / contraction means 48 is disposed above the support column 3. Thus, when the user is hung on the hanger 51 with a sling sheet, the user's lower limbs are configured not to come into contact with the expansion / contraction means or the support, so that the user's lower limbs come into contact with the structural member. Discomfort can be reduced.
In addition, it is easy for the assistant to go around the user's lower limbs, and the physical burden on the assistant can be reduced by reducing the care operation in an unreasonable posture.
Furthermore, the workability of the assistant can be improved by making the arm part 4 compact by using the arm part 4 as a cross link mechanism.
In addition, when the user is hung by the sling seat, the member constituting the arm unit 4 can be arranged at a position far from the face, so that the user's feeling of pressure can be reduced.

Next, the relationship between the first link arm 41, the second link arm 42, the third link arm 47 and the hanger part 5 when the arm part 4 is raised and lowered moves the hanger part 5 from the lowest position to the highest position. Will be described.
First, FIG. 5 shows the hanger portion 5 in the lowest position. In this lowest state, the third link arm 47 and the third link are mainly used when the user is sleeping directly on the floor or when using a bedding having a small step difference from the floor such as a futon or an extremely low bed. The hanger part 5 supported by the arm 47 is in a straight line in the vertical direction.

Next, FIG. 6 shows a state in which the hanger portion 5 is on the way from the lowest position shown in FIG. 5 to the highest position (the hanging point of the hanger portion 5 and the shaft member 43 of the first link arm 41 are in a substantially horizontal position). ing.
First, when the elevating switch 53 of the hanger part 5 is pushed from the state of FIG. 5, the expansion / contraction means 48 is driven and extended. Then, in accordance with the extension of the expansion / contraction means 48, the first link arm 41 performs an arc motion around the shaft member 43 and rotates upward. Similarly, the second link arm 42 and the third link arm 47 connected to the first link arm 41 also try to rotate upward.
However, while the shaft member 46 connecting the second link arm 42 and the third link arm 47 moves from the right end 421a of the elongated hole 42a of the second link arm 42 to the left end 421b, the third link arm 47 Thus, the force of the expansion / contraction means 48 is not applied, and the third link arm 47 and the hanger portion 5 remain in a straight line in the vertical direction.
When the first and second link arms 41 and 42 rotate and the shaft member 46 reaches the left end portion 421b of the long hole 42a of the second link arm 42, the extending and lowering means 48 further extends. The force of 48 is transmitted to the third link arm 47, and the shaft member 46 serves as a force point and the shaft member 45 serves as a fulcrum as in the lever principle, and the tip end of the third link arm 47 rotates upward as an action point.
Then, the hanger portion 5 pivotally attached to the tip of the third link arm 47 also rotates upward as the third link arm 47 rotates.
While maintaining this state, the arm part 4 and the hanger part 5 are moved to the highest position of the hanger part 5 shown in FIG.
In addition, when raising / lowering the hanger part 5 from the highest level to the lowest level, it becomes a procedure reverse to the procedure from the lowest level to the highest level, and the components also operate in reverse.

In the description so far, the elongated hole 42a is provided on the rotating distal end side of the second link arm 42. However, as another embodiment, the elongated hole 32a is provided on the rotating proximal end side as shown in FIG. You can also.
Even in the case of FIG. 11, the arm portion 4 moves in the same manner as the case where the second link arm 42 is provided with the long hole 42 a as shown in FIGS.
More specifically, first, the first link arm 41 performs an arc motion around the shaft member 43 and rotates upward as the telescopic means 48 is driven, and the second link arm 42 attempts to rotate.
And while the shaft member 44 of the rotation base end side of the 2nd link arm 42 located in the right end part 321a of the long hole 32a drilled in the support | pillar bracket 32 moves to the left end part 321b, it is a 3rd link arm. 47 does not receive the force of the expansion / contraction means 48.
Then, when the extension of the extension / contraction means 48 further proceeds, the force of the extension / contraction means 48 is transmitted to the third link arm 47, the shaft member 44 serves as a power point, the shaft member 45 serves as a fulcrum, and the tip of the third link arm 47 serves as an action point. Move.
Thus, the effect of this invention can be acquired by providing a long hole in either one end side of the shaft member 44 of the 2nd link arm 42, or the shaft member 46. As shown in FIG.
In addition, since the arm part 4 is configured as shown in FIG. 11, the elongated hole 32a can be completely hidden by a cover member (not shown) provided near the handles 33, 33. It can be assumed that there is no concern about the body being caught.

Next, the shift of the suspension point when the arm part 4 and the hanger part 5 are raised and lowered along with the expansion and contraction of the lifting means 48 described above and when the arm part and the hanger part of the conventional nursing care lift device are raised and lowered will be described. The suspension point described here is a point (shaft member 54) connecting the third link arm 47 and the hanger part 5.
FIG. 9A shows the lifted state of the arm part 4 and the hanger part 5 of the conventional lift device for nursing care. FIG. 9B shows the lifted state of the arm portion 4 and the hanger portion 5 of the lift device for care of the present embodiment.
Then, the suspension point P _a lowest position, (located, horizontally suspended point relative to the rotation center) of the most distant from the rotation center and the suspension point P _b, the highest suspension point P _c Compare these three points.
As an explanation of the symbols in FIG. 9, the trajectory of the suspension point moving from the suspension point P _{a to} P _c is the locus R _p , and the longitudinal displacement between the suspension point P _a and the suspension point P _b is the width. A width W _b is defined as a width in the front-rear direction between W _a and the suspension point P _b and the suspension point P _c .
In addition, the lowest position (suspension point P _a ) and the highest position (suspension point P _c ) of the conventional arm rotation type care lift device and the care lift device of the present invention are the same position.

First, the arm 4 of a conventional nursing lifting device, the upper pivot with circular motion while always maintaining a constant distance strut as the pivot center from suspension point P _a of the hanger portion 5 to suspension point P _c to order, in any case from the width W _a and suspension point P _b of suspension point P _b from suspension point P _a width W _b of the suspension point P _c becomes what deviation is large .
On the other hand, the state of the arm part 4 of the lift device 1 for care of a present Example is demonstrated.
First, when the upper rotation between suspension point P _b from suspension point P _a is the shaft member 46 to the left end portion 421b from the right end 421a of the long hole 42a of the second link arm 42 as described above rolling since pressure on the third link arm 47 by moving is not transmitted, although the first link arm 41 is moving upward once the third link arm 47 can be reduced width W _a will remain suspended.
Then, when the upper rotation between suspension point P _c from suspension point P _b is stretchable than the second link arm 42 by the shaft member 46 reaches the left end portion 421b of the elongated hole 42a as described above by the force of the means 48 is transmitted, since the third link arm 47 with the first link arm 41 is moving upwardly times is moving upwards times, the third link arm 47 is moved to the suspension point P _b side in it is possible to suppress the spread of the distance W _b.
Thus, the force of the expansion / contraction means 48 is not transmitted to the third link arm 47 when rotating upward from the lowest position to the horizontal position, and the rotation of the expansion / contraction means 48 when rotating from the horizontal position to the highest position. In any case by transmitting the force to the third link arm 47, the care of the present invention is more effective than the widths W _a and W _b of the suspension point of the arm portion 4 of the conventional lift device for care. The widths W _a and W _b of the suspension point shift of the arm portion 4 of the lift device 1 can be reduced.
This can be seen by comparing the trajectory R _p. Conventional care lift system the boundary of suspension point P _b in the horizontal position, but displaced gradually spaced apart as to respectively pivot suspension point P _c of the suspension point P _a and the highest lowest increases , the care lift apparatus 1 boundary suspension point P _b of the horizontal position of the present invention, between the suspension point P _a of the lowest suppresses the deviation as a third link arm 47 does not act, the highest The third link arm 47 acts between the upper suspension point _Pc and the displacement is suppressed.
By configuring in this way, when moving from a place with a different height, such as when transferring from a bed to a wheelchair or the like, even if the raising / lowering position of the hanger part 5 is changed, Since there is little misalignment, the positioning of the user's buttocks becomes easy, and there is an effect that the work of finely adjusting the position where the assistant sits can be reduced as much as possible.
Further, since there is little displacement of the sitting position, it is possible to reduce discomfort such as a user's buttocks at the time of sitting.
In addition, since the third link arm 47 rotates in a direction away from the arm portion 4 and the support column 3 when ascending, the user's lower limb is used as a component constituting the support column 3 when the user is suspended from the sling seat. Since it becomes difficult to contact, it can transfer more comfortably.

In the present embodiment, deviation occurs in the suspension point P _c of the horizontal position of the suspension point P _b and the highest position, it is also possible to eliminate this deviation.
For example, while care site care lift device 1 not used to scoop up the user from the floor or the like, mainly in the case of assuming only ERROR such chairs and beds, the suspension point P _b of P _c The arm portion 4 is configured to be rotatable only at the position, and the lower side is extended from the position where the shaft member 45 of the third link arm 47 is pivotally attached, thereby increasing the diameter of the third link arm 47 that rotates in an arc. This eliminates the gap between the lowest and highest positions. Moreover, since the rotation range of the hanger part 5 can be adjusted by changing the length of the long hole 42a of the 2nd link arm 42, the same effect as changing the length of the 3rd link arm 47 is obtained. Can be obtained. Thus, it can arbitrarily set to the structure which reduces the shift | offset | difference of the hanger part 5 more according to a use environment.

Next, a method for transferring the user from the bed using the care lift device 1 to the wheelchair will be described.
First, the sling sheet is laid under the user, and the user is hung on the hanger part 5 with the sling sheet.
Next, the base legs 22 and 22 of the base part 2 of the care lift device 1 are passed under the bed.
Then, the elevating switch 52 of the hanger part 5 is operated to lower the hanger part 5 to the position where the strap of the sling seat is hung, and the straps are hung on the hooks 51c and 51c.
Then, the assistant operates one of the lift switches 52 of the hanger part 5 to raise the hanger part 5.
Then, the assistant holds the handles 33 and moves the care lift device 1 to the target wheelchair.
Then, the base portion 2 of the care lift 1 and the wheelchair face each other, and the assistant operates the lift switch 52 to lower the hanger portion 5 to seat the user on the wheelchair.
Then, the sling sheet strap is removed from the hooks 51c, 51c,..., And the sling sheet is removed from the user.
The above is the transfer method from the bed to the wheelchair using the care lift device 1.

When this series of transfer operations is performed using a conventional cord type lifting switch, there is a problem that the cord type lifting switch must be repeatedly housed and taken out in a storage place such as a hook for each operation. Moreover, since an assistant repeats a movement to the hanger part 5 and the handles 33 and 33, there is an increased risk of disconnection due to intermittent bending of the wiring.
On the other hand, the care lift device 1 according to the present invention has the lifting / lowering switch 52 in the hanger part 5, so that there is no trouble of storing and taking out. Further, since the assistant always operates on the side of the user when the strap is attached to and detached from the hook, for example, when the strap of the sling seat is not accurately hooked on the hook, it can be immediately noticed and changed again.
Therefore, the danger of the user's falling can be avoided, and both the user and the assistant can use it with peace of mind.
In addition, when the user tries to operate the lifting / lowering switch 52 while reaching his hand to the hanger unit 5, the lifting / lowering switch is protected by a plate or the like so that the lifting / lowering switch 52 cannot be reached from below. Just do it.

  In this embodiment, the floor-running base unit 2 is used, but it can be pivoted to the column such as a stationary type in which the base unit is integrated with the bed or a fixed type in which the column is fixed to the wall by renovating the house. If it is the arm part structure supported by this, it can set arbitrarily according to a user's use environment.
