Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a care device for assisting a user (care receiver) who is difficult to stand up by himself to stand up.

[0002]

2. Description of the Related Art Conventionally, as a nursing care device for assisting a care receiver who is difficult to stand up by himself, a care bed having a function of raising from a recumbent state to a sitting position, a support surface on a lower body side in a sitting position. With a function of turning the robot 90 degrees in the horizontal plane to facilitate the transition to standing and walking motions, and to raise or walk by lifting the body upward from the sitting position on the floor surface There are known electric chairs and the like that facilitate the transfer to the electronic chair.

[0003] However, in the above-mentioned conventional nursing care apparatus, although it is possible to assist a person lying on a bed or a person sitting on a tatami mat or a floor, the tatami mat or the floor is assisted. It is not possible to assist the standing motion of a person lying on a low position such as a surface.

[0004] Therefore, the present applicant has already mounted a frame which is placed substantially horizontally on the floor surface and on which a support surface for supporting the user is formed, and the head of the user of the frame. A double cylinder provided with an inner cylinder that is disposed on the floor near the one end of the side and that can be displaced vertically in a vertical outer cylinder, and one end is fixed to the other end of the frame, There has been proposed a nursing care device having a belt or a wire that is wound around a roller supported on an outer cylinder and then wound up by a winding drive mechanism on the floor (Japanese Patent Laid-Open No. 11- ★★★★).
issue). In this care device, one end side (head side) of the frame rises along the outer cylinder by winding up a belt or a wire by a winding drive mechanism from a horizontal state where the frame is substantially along the floor surface. , One end of the frame abuts a regulating member provided at the tip of the inner cylinder,
A user lying horizontally on the support surface of the frame placed on the floor is almost in an upright position by displacing the frame to an almost vertical upright state while the inner cylinder rises in the outer cylinder. , The user can easily stand on the floor or shift to the walking state.

[0005] Further, when the user lying on a support surface such as a bed is placed in a sitting position or vice versa, the position corresponding to the waist of the support surface is bent or extended. However, if the support surface is simply bent, the back of the user will friction with the support surface to sense a kind of tension, and at the same time, the support surface on which the thighs ride and the support surface on which the back rides Since the waist of the person enters the formed V-shaped space, a feeling of pressure is sensed on the abdomen. Conventionally, as a mechanism for relieving the feeling of tension or pressure, a bellows type articulated joint mechanism is used to bend the position corresponding to the waist of the nursing bed, or the applicant has already proposed As shown in the figure, a single joint is used to bend the position corresponding to the waist of the frame, and the longitudinal direction (the height direction of the user) is closer to the head than the bent portion corresponding to the waist on the support surface of the frame. A mechanism in which a seat member that is slidable and displaceable is disposed on a single joint, and a cam-shaped contact plate is integrally formed with a single joint, and the contact plate moves the seat member up and down in synchronization with bending and stretching of the waist. (JP-A-11- ☆☆☆☆) is known.

[0006]

Meanwhile, among the above-mentioned conventional nursing care devices, a device for immediately lifting a user lying down near the floor to a standing state by a series of operations is disclosed in Japanese Patent Application Laid-Open No. 11- ★. Although it is only the device disclosed in ★★★, this proposed device requires a complicated and large-scale drive mechanism that uses a double cylinder and whose inner cylinder extends above the standing state of a person. In addition, in the upright state, the tip of the inner cylinder is higher than the top of the frame, so that the overall height of the apparatus is large, and even in the non-use state, the required space is large, which is an obstacle to cleaning and the like.

[0007] Among the conventional mechanisms for alleviating the feeling of strain on the back or the pressure on the abdomen when shifting from the lying state to the sitting state or from the sitting state to the lying state, a bellows type articulated joint mechanism is used. What is used not only has a complicated structure, but also has a possibility that dust may enter the gap in the bellows portion. On the other hand, the one disclosed in Japanese Patent Application Laid-Open No. 11- ☆☆☆☆, in which a plate is integrally formed on a single joint and the seat member slides, does not have the above-mentioned problem, but the movement of the seat member is described. There is a problem in that the amount of the medicine cannot be increased, and the effect of alleviating the feeling of tightness in the back or the feeling of pressure in the abdomen is small.

The present invention has been made in view of such circumstances, and a simple and particularly compact structure in the height direction allows a user lying down near the floor to be immediately operated by a series of operations. It is a main object of the present invention to provide a nursing care device that can be lifted up to a standing state, and can be easily folded when not in use and can be stored in a closet or the like.

Another object of the present invention is to provide a nursing care device capable of lifting from a lying state near the floor surface to an upright state at a stretch, by simply adding a simple structure, and Another object of the present invention is to provide a nursing care device that does not give a feeling of strain on the back of the user or a feeling of pressure on the abdomen during the reverse operation.

[0010]

In order to achieve the above-mentioned main object, a care device according to the present invention forms a support surface for supporting a user on the front side, and uses the support device supported on the support surface. Rollers are provided at a plurality of positions in the longitudinal direction including at least positions corresponding to the waist and the knees of the user, and are rotatable at both ends in the longitudinal direction and substantially at the center on the back side. A bed frame provided with a slope having a height from the installation surface that is higher at one end side in the longitudinal direction of the bed frame and guides each roller from below, and one end at a substantially central portion in the longitudinal direction of the bed frame. A belt or a wire that is wound by the take-up drive mechanism and pulls the bed frame toward one end in the longitudinal direction, and is driven in synchronization with the drive of the take-up drive mechanism. An actuator for bending a node or a flexible portion provided at a position corresponding to the knee, wherein the belt or wire is wound around a sheave supported above and near the top of the slope. The bed frame is wound up by the winding drive mechanism located below the bed frame, and the support surface of the bed frame is positioned near the installation surface of the apparatus in accordance with the amount of belt or wire winding by the winding drive mechanism. From a substantially horizontal state along the installation surface, the joint or flexible portion corresponding to the waist portion is bent inward at a predetermined angle, and the posture is substantially vertically upright with the one end side positioned upward. It is characterized by being configured to change (claim 1).

According to the configuration of the invention according to claim 1,
A belt or a wire fixed to a substantially central portion in the longitudinal direction of a bed frame forming a user's support surface on the front surface is wound up by a winding device, so that a roller on the back surface of the bed frame is guided by a slope and a head portion. When the side rises gradually and the belt or wire fixing position approaches the sheave arranged near the top of the slope, the head of the bed frame is pulled up above the sheave and the slope and corresponds to the waist. The knot or the flexible part is bent appropriately. By synchronizing with this operation, the joint or the flexible portion provided at the position corresponding to the knee is bent by driving the actuator, so that the human body on the support surface has the toe with the knee appropriately bent. It is located in the vicinity of the installation surface of the device and stands up with its waist appropriately bent. The height of the slope and the sheave may be lower than the end of the frame head in the upright state because one end of the belt or the wire is fixed to the substantially central portion in the longitudinal direction of the bed frame. Compared with the conventional proposed device in which the cylinder rises to the bed frame head side tip in the upright state, it is possible to achieve compactness in the height direction. In addition, since the support surface of the user can be bent at least at positions corresponding to the waist and the knee, the required area on the horizontal plane can be reduced by appropriately folding the frame when not in use.

Here, in the present invention, it is possible to adopt a configuration in which the bed frame can be separated from the slope and the winding drive mechanism (claim 2). Sometimes, only the bed frame is detached and folded as appropriate, so that it is possible to store it more compactly.

In the present invention, in addition to the flexible portions, the above-described knots or bends that bend during use in the bed frame cannot be bent by the detent pins during use. A configuration in which a bendable node or a flexible portion is provided may be adopted (claim 3). By adopting the configuration of the invention according to claim 3, the bed frame can be made more compact when not in use. Thus, the bed frame and the winding drive mechanism can be stored compactly without being separated.

Further, in order to achieve the above-mentioned other objects,
According to a fourth aspect of the present invention, in addition to the configuration of the first, second, or third aspect of the present invention, on the support surface of the bed frame,
A seat member slidable in the longitudinal direction of the bed frame is provided on the head side (side on which the slope is higher) than the joint or flexible portion corresponding to the waist of the user, and the seat member is By the moving mechanism synchronized with the driving of the winding drive mechanism, when the bed frame shifts from the horizontal state to the upright state, on the head side on the support surface of the bed frame,
Further, it is characterized by being configured to move by a predetermined amount to the opposite side when shifting from the standing state to the horizontal state (lying state).

According to the configuration of the invention according to claim 4,
The seating member on the bed frame moves to the head side or the opposite side in conjunction with the drive of the winding drive mechanism, so that the back swelling feeling and the abdominal pressure feeling are alleviated without using an articulated joint. be able to.

In the structure for reducing the feeling of tension on the back and the feeling of pressure on the abdomen due to the movement of the seat member, the invention according to claim 5 employs a simple structure without using a dedicated actuator. By moving the seat member by a necessary amount, the feeling of tightness in the back and the feeling of pressure in the abdomen can be almost completely eliminated.

In other words, in the invention according to claim 5, the moving mechanism of the seat member is positioned below the bed frame and closer to the head than the joint or flexible portion corresponding to the waist. A pulley, a knot comb corresponding to the waist, a guide roller provided below the flexible portion, and one end fixed to the seat member on the head side of the moving pulley, wound around the moving pulley and inverted. And the other end is fixed to the bed frame, and the other end is fixed to the bed frame after being wound around the guide roller and the first belt or wire for the seat member whose other end is fixed to the bed frame.

The operation of the above embodiment of the present invention will be described with reference to FIG.
This will be described with reference to FIGS. By driving the drive motor 93 from the lying state shown in FIGS. 1 and 2 to wind up the belt 8, the posture of the bed frame 1 changes as shown in FIGS. That is, when the start of winding of the belt 8 is commanded from the state shown in FIGS. 1 and 2, the bed frame 1 is drawn toward the slopes 3a and 3b, and the roller 21 on the head side rises on the slopes 3a and 3b. To go. In this state, since the center roller 22 is still rolling on the installation surface F, the waist joint 12 is gradually bent inward.
The electric cylinder 4 also starts to contract at the same time as the winding start command, and the seat is in a seating state as shown in FIG. In this state, the bulging portion 11 of the bed frame 1 comes into contact with the convex portion near the top of the substantially S-shaped curve of the slopes 3a and 3b, and the roller 21 is separated from the slopes 3a and 3b.

When the winding of the belt 8 is continued, the roller 22 at the center begins to climb on the slopes 3a and 3b, and at the same time, the roller 21 on the head side supports the columns 7a and 7b.
And moves vertically upward, so that the waist joint 12 is further bent as shown in FIG. If the winding of the belt 8 is further continued, the roller 23 on the toe side also

The waist joint 12 is bent at 123 °, and the bed frame 1 between the waist joint 12 and the knee joint 13 is in an inclined state in which the knee side is located slightly below, so that the user can easily stand up.

The drive motor 93 is moved from the upright state shown in FIG.
Is rotated in the opposite direction to that described above, the belt 8 is rewound from the winding drum 91, and returns to the lying state by the operation reverse to the above due to the weight of the bed frame 1.

When the apparatus is not used, the bed frame 1 is disassembled by the separating mechanisms 14a and 14b as necessary, and the belt connecting fastener 81 is removed.
A part on the head side of the bed frame 1 including the winding drive mechanism 9 and the slopes 3a and 3b and a large part of the bed frame 1 including the waist joint 12 and the knee joint 13 are separated and stored in, for example, a closet. It is possible to do.

What is particularly noteworthy in the above embodiment is that
A user lying down near the installation surface (floor surface) F of the device can be immediately shifted to a standing or walking state by a series of operations driven by the drive motor 93, and a bed frame in the standing state. Although the head-side tip of 1 is as high as the height of a person, the mechanical parts such as the slopes 3a and 3b and the columns 7a and 7b that guide it remain at about half the height. Another advantage is that the overall height of the device in the upright state can be minimized.

Here, in the above embodiment, the bed frame 1 is disassembled in the separation mechanisms 14a and 14b, so that the mechanism part having a relatively low height and most of the bed frame 1 are separated. The bed frame 1 is appropriately folded at the waist joints 12 and the knee joints 13 so as to make both of them separated and compact for easy storage. By providing the joints for use, it is possible to make the mechanism part and the bed frame 1 compact so that they can be stored in a closet or the like without being separated.

FIG. 7 shows an example. In this example,

15b, for example, holes 16a, 1
6b, and a structure is adopted in which the rotation can be restricted by inserting a rotation preventing pin into the holes 16a and 16b during use. By adopting such a mechanism, it becomes possible to store the mechanism portion and the bed frame 1 in a closet or the like without separating them as shown in FIG. In FIG. 7, a caster 51 and an installation pedestal 52 are provided on the lower surfaces of the pedestal plates 5a and 5b.
By removing or raising the mounting base 52, the entire apparatus can be supported and moved by the casters 51.

According to the above-described embodiment, the posture of the user lying on the floor near the floor due to the movement of the bed frame 1 and the bending of each joint is changed to the standing state after sitting on a chair. It is necessary to move the hip joint 1
At the time of bending, the user feels a sense of tension on the back of the user and a sense of pressure on the abdomen, as described above. Another embodiment of the present invention having a function of eliminating such discomfort will be described below.

FIG. 8 is a side view of a main part of another embodiment of the present invention having the above-described functions, and FIG. 9 is a plan view showing the entire structure with the base plate 101 removed. The feature of this example is that a base plate (seat member) 10 slidable in the longitudinal direction with respect to the bed frame 1 between the bed frame 1 and the mat 1M on the head side of the waist joint 12.
1 and a moving mechanism for slidingly displacing the base plate 101 in synchronism with the flexion and extension of the waist joint 12.

The moving mechanism of the base plate 101 is the moving pulley 10
2, which enables the base plate 101 to be moved in a required direction by an amount corresponding to the amount of bending of the waist joint 12 of the bed frame without using a dedicated actuator.

That is, on the bed frame 1, slide rails 101a are provided on both sides of the surface above the waist joint 12, and the base plate 101 is slidably supported on the slide rails 101a. One end of a first base plate belt 103 is fixed near the head-side end of the base plate 101 (the fixing position is indicated by A in FIG. 8), and the first base plate belt is fixed. 103 is once extended to the head side, and is then wound around core rods 21a of the left and right rollers 21 at the tip of the head side, inverted and extended to the toe side, and located closer to the head than the waist joint 12. It is wound around the moving pulley 102 for about half a circumference, and the other end is fixed to the bed frame 1 (the fixing position is indicated by B in FIG. 8).

One end of a second base plate belt 104 is fixed to the moving pulley 102, and the second base plate belt 104 is attached to the left and right After being wound around the guide roller 105 supported by the core rod 22a of the roller 22, the other end is fixed to the bed frame 1 at the foot of the hip joint 12 (the fixing position is indicated by C in FIG. 8). ).

Further, a constant load spring 10 having a casing fixed to the back side of the bed frame 1 is provided on the base plate 101.
The tip of the spring body 6 is fixed (the fixing position is indicated by D in FIG. 8), and the base plate 101 is constantly urged toward the toes. The parts other than the base member 101 and its moving mechanism are exactly the same as those of the previous embodiment.

According to this embodiment, the driving motor 93
As shown in FIGS. 10 to 13, the bed frame 1 moves and bends in the same manner as in the previous embodiment, and at the same time, the second base plate belt 104
As a result, the movable pulley 102 is pulled toward the toe by an amount corresponding to the amount of bending of the guide roller 105 around the guide roller 105. By the movement of the moving pulley 102, one end of the first base plate belt 103 is pulled toward the toe. This first base plate belt 103 is
Since it is inverted and fixed to the base plate 101 at 1a,
As a result, the base plate 101 is pulled toward the head against the urging force of the constant load spring 106 due to the movement of the moving pulley 102 in the above direction. The first base plate belt 1
The amount of pulling of the base plate 101 by the use of the moving pulley 102 is twice as large as the amount of pulling of the second base plate belt 104 toward the toe by the winding around the guide roller 105. The movement amount of the base plate 101 is shown in FIGS. 8 and 10 to 13 together with an example of the distance between the bending amount of the waist joint 12 and the reference point of the bed frame 1 of the base plate 101. FIG. 1 shows a transition from the sitting state to the chair state in proportion to the amount of bending of the lumbar joint 12.
In the state of 1, the amount of bending of the waist joint 12 and the base plate 10
1 moves to the head side the most.

When returning from the standing state to the lying state, the movable pulley 102, the first and second base plate belts 103 and 104 operate in the reverse manner to the above, and the base plate 101 It moves in the opposite direction due to the urging force.

The base plate 101 in the above embodiment
It has been experimentally confirmed that the user can hardly perceive the back stiffness and the abdominal pressure when moving from the recumbent state to the upright state by moving a sufficient amount in synchronization with the bending of the lumbar joint 12 of the user. .

In the above embodiment, the second base plate belt 104 is fixed to the bed frame 1 after being wound around the guide roller 105, but may be fixed to the guide roller 105. However, in this case,
The guide roller 105 needs to be fixed to the toe side beyond directly below the vertical.

In the above embodiment, the base plate 101 is moved by the mechanism using the moving pulley 102 without using a dedicated actuator. However, the bending of the lumbar joint 12 is performed using a separate dedicated actuator. It is also possible to move the base plate 101 in synchronization with.

Further, in each of the above embodiments, the belt 8 for moving the bed frame 1 and the first and second base plate belts 103, 104 may of course be wires.

The material of the bed frame 1 is not particularly limited. For example, the bed frame 1 can be made of wood or sheet metal steel, and when made of wood, the weight can be reduced.

Furthermore, the guide rollers 71a, 71b provided on the tops of the columns 7a, 7b are replaced with the columns 7a, 7b.
The top of b may be rounded, and the back surface of the bed frame 1 may be guided by the curved surface. When the bed frame 1 is guided by the curved surface of the top of the guide rollers 71a, 71b or the columns 7a, 7b, these are provided on both left and right end portions on the back side of the bed frame 1 in order to prevent the bed frame 1 from shifting left and right. A groove may be provided to fit the groove, or grooves may be formed on the surfaces of the guide rollers 71a and 71b, and a ridge fitting into the groove may be provided on the back surface of the bed frame 1. Alternatively, when the bed frame 1 made of sheet metal steel is adopted, the guide rollers 7
By fabricating 1a and 71b with permanent magnets, the left and right displacement of the bed frame 1 can be prevented.

[0046]

As described above, according to the present invention, a user lying in a lying state near the installation surface (floor surface) can be immediately shifted to a standing state or a walking state by a series of operations. Moreover, when the bed frame is standing,
No other members appear above the tip of the bed frame, thus minimizing the overall height of the device in the upright position. When not in use, it can be relatively easily disassembled or folded and stored in a closet or the like.

Further, a seat member (base plate) is slidably provided in the longitudinal direction of the frame on the head side of the waist joint on the support surface formed by the bed frame, and the seat member is attached to the waist of the bed frame. By adding a configuration in which the head is moved to the head side in synchronization with the bending of the joint, the user does not have a sense of thrust on the back or a feeling of pressure on the abdomen when shifting from the lying state to the standing state. The movement of the seat member is performed by a mechanism that utilizes the bending motion of the lumbar joint using a belt and a moving pulley, so that there is no need to use a dedicated actuator, and a feeling of tension and pressure is felt. A sufficient stroke can be obtained so as not to cause the stroke.
