[Conventional technology and its problems] For bedridden patients who are unable to move on their own, even with dedicated care at home and thorough medical treatment, the position on which the patient's weight is placed remains the same. , prone to bedsores. In addition, having a long-term companion not only costs money, but also puts a psychological burden on the sick person, resulting in an unpleasant daily experience for the entire family.

Therefore, there is a desire for a bed device for bedridden patients that can automatically turn over and prevent bed sores without the need for human assistance, and that also allows the user to be supported by pillows each time they turn over. .

[Purpose of the Invention] This invention was made in consideration of the above circumstances, and its purpose is to enable a person to turn over automatically at all times without the need for an attendant, and to spread the weight evenly so that a person can lie on his side for a long time. This prevents pressure sores and allows you to freely view left and right sides, which is convenient.In addition to reducing costs and psychological burden, the bed board can be used from its normal position. The user's head is well supported by the pillow as the user shifts to the desired position, and the user turns over so that the pillow falls to the left and right, so the futon does not shift to the side and there is no gap between the futon and the futon on the back and chest sides. It is an object of the present invention to provide a bed device for sick people etc. which has a beneficial effect.

[Means for Solving the Problems of the Invention] The present invention comprises a bed provided in a substantially horizontal state at a predetermined distance from an installation surface, and a bed divided into at least three parts along the height direction. The first, second, and third bed plate portions formed by the above-mentioned methods are provided at each connecting portion of these adjacent bed plate portions, and the first and second bed plate portions or the second and third bed plate portions are connected to each other at the connecting portions. a pivot member supporting the bed plate portions of the bed plate portions so as to be alternately displaced between a normal position in a horizontal state and a use position in which the bed plate portions are bent downward into a trough shape; a driving member that is driven to be displaced between a rest position and a tilted position; a pillow device that is provided on both sides of the head of the bed plate to support the head when the user is in a sideways position; The system employs a configuration that includes a mechanism for moving the camera between positions.

[Operations and Effects of the Invention] According to the present invention configured as described above, the bed plate portions of mutually adjacent beds are alternately displaced between the normal position and the use position by the drive member, so that the bed plate portions of the beds adjacent to each other are alternately displaced between the normal position and the use position. The patient's weight is alternately applied to different parts of the body, and the patient can automatically turn over and turn over without assistance. As a result, bedsores are of course prevented,
Different views can be obtained alternately on the left and right sides, which is convenient for visiting people and seeing posted items.In the long term, it reduces costs and the psychological burden on patients.In addition, the bed board can be moved from its normal position to its use position. As a result, the user's temporal region is well supported by the side pillow portion, resulting in excellent effects.

The rod 20a from the cylinder 20 is provided so as to be able to reciprocate on a U-shaped rail 22 with an open upper surface via a roller 23 at the tip. Reference numeral 24 denotes a fork-shaped moving rod disposed between the first bed plate part 7 and the hydraulic cylinder 20, the lower end of which is rotatably supported by the roller 23, and the upper end of which is rotatably supported by the first bed plate part 7 and the hydraulic cylinder 20. It is rotatably supported on the bottom surface of the portion 7 by a pin 25. Reference numeral 26 denotes a support rod, whose upper end is rotatably supported by the pin 25, and whose lower end is formed with a long hole 26a extending in the axial direction. The long hole 26a of this support rod 26 is fitted into a pin 28 provided on a mounting piece 27 of the bottom plate 21 so as to be movable in the longitudinal direction. The length of this support rod 26 can be adjusted in the axial direction by a turnbuckle mechanism 29. When the first bed plate section 7 is in a horizontal state, the turnbuckle mechanism 29 is operated to tension the support rod 26 so that the lower end of the inner circumference of the elongated hole 26a contacts the pin 28.

On the other hand, two hydraulic cylinders 30 are arranged on the bottom plate 21 in the same manner as described above, corresponding to the third bed plate part 9. A rod 30a from each hydraulic cylinder 30 can be moved back and forth on a rail 32 via rollers 31. The moving rod 33 has a fork shape, has an upper end rotatably supported by a pin 34 on the bottom surface of the third bed plate portion 9, and a lower end rotatably supported by a roller 31. Further, the support rod 35 can be adjusted to expand and contract in the axial direction by a turnbuckle mechanism T, and a long hole 35a at the lower end is movably fitted into a pin 37 of the mounting piece 36.

Now, 38 and 39 are between the first and second bed plate parts 7, 8 and between the second and third bed plate parts 8, 9.
The side pillows 38 each have an L-shaped stay 40 that rises slightly from the bed board, and its horizontal part 40a has a receiving part 41 for the side of the user's head. It is set up. In the vertical portion 40b of the stay 40, elongated holes 42, 43 are formed on the left and right, oriented vertically, and bolts 44, 45 are screwed into the receiving portion 41 through the elongated holes 42, 43. By retightening these bolts 44 and 45, the height of the receiving part 41 can be adjusted with respect to the vertical part 40b of the stay 40 within the vertical dimension range of the elongated hole. 70 is stay 40
This is a stopper provided in a protruding state on the vertical piece 40b of the vertical piece 40b, which abuts on the upper end edge of the rising piece 46, and
The stay 40 shown in the figure is prevented from inadvertently rotating in the direction of arrow V and is held in a substantially horizontal state. One end of the vertical portion 40b of the stay 40 is rotatably supported by a pin 47 at the tip of a rising piece 46 from the second bed plate portion 8, and the other end is rotatably supported by the tip of a rising piece 46 from the first bed plate portion 7. It is rotatably supported by a pin 50 via a link 49 at the tip of the upper piece 48 . An elongated hole 49a is formed in the lower end of the link 49 in the axial direction, and a pin 51 at the tip of the upright piece 48 is fitted into the elongated hole 49a so as to be movable in the axial direction.

On the other hand, the side pillow 39 also has a stay 52 similar to the side pillow 38 described above, and a receiving portion 53 is provided on the stay 52. This receiving portion 53 is similar to the receiving portion 4 described above.
1, the height can be adjusted in the vertical direction with respect to the stay 52. One end of the vertical portion 52b of the stay 52 is rotatably supported by an upright piece 54 from the second bed plate portion 8 via a pin 55. Further, the other end of the stay 52 is connected to the third

and is rotatably supported via a pin 58. A long hole 57a oriented in the axial direction is formed at the lower end of the link 57, and a pin 59 of the upright piece 56 is movably fitted into the long hole 57a. A stopper 71 is formed on the stay 52 similarly to the stay 40, and this stopper comes into contact with the upper end edge of the upright piece 54 to prevent the stay 52 from rotating inadvertently. Note that 60 and 61 are connected to the first and second bed plate parts 7 and 8 and to the second and third bed plate parts 8 and 9 so as to form a V-shape with each other. This is a chamfered portion formed. Reference numerals 62 and 63 indicate stoppers formed inside the supports 1 and 2, and these stoppers are provided with the first and third bed plate parts 7 and 9.
Convex portions 64 and 65 provided on the side surfaces of the base plate are adapted to block each other.

Next, the operation of the above configuration will be explained.

First, place the mattress 6 on the first to third bed board parts.
6, a comforter 67 is prepared, and the user U, such as a sick person, rests on his or her back with his/her head resting on the main pillow 68 and positioned on the second bed board part 8. In this state, as shown in FIGS. 1 and 2, the first, second and third bed plate portions 7, 8 and 9 are in normal positions horizontal to each other.

At this time, if the user wishes to turn over, the hydraulic cylinder 30 is driven to move the rod 30a in the direction of arrow A shown in FIG. Then, roller 31
runs along the rail 32 in the longitudinal direction to its fullest extent and then stops. Along with this, the moving rod 33 moves the lower end of the roller 3
It moves in the direction of arrow A while rotating in the direction of arrow B around 1. The upper end of the moving rod 33 rotates in the direction of the arrow C around the pin 34 and moves downward as shown by the arrow D, so that the fork-shaped moving rod 33 moves toward the rod 30a.
It receives the rod 30a and becomes integral with the rod 30a, and is located flush with each other. In the process of the upper end of the moving rod 33 moving downward, the second and third bed plate parts 8 and 9
The hinge mechanism 11 allows the second bed plate section 8 to rotate relative to the hinge mechanism 11.
0 in the direction of the arrow E, and the third bed plate portion 9 comes to be rotationally displaced in the direction of the arrow F by the rod 15. As a result, the second and third
The bed plate parts 8 and 9 are bent downward at approximately 90 degrees at the hinge mechanism 11 and displaced to the use position, and
As seen in the figure, the second and third bed plate parts 8, 9
This creates a valley-like depression inside. With this displacement, the protrusion 64 separates from the stopper 62, while the support rod 35 rotates in the direction of arrow G about the pin 37 and becomes substantially in line with the moving rod 33.
The rod 15 rotates about the arm 13 in the direction of arrow H and is displaced from a vertical position to an inclined position.

At this time, the second bed board 8 changes from a horizontal position to a tilted state, so that the user U changes from a supine position to a lying state in which the user's own weight is distributed to the third bed board 9. As the bed plate section is displaced from the horizontal position to the use position, the upright piece 54 is displaced from the vertical position to the inclined position, but since the link 57 rotates in the direction of arrow I, the stay 52 is moved to the receiving position. 53 in the same direction, and is displaced parallel to the third bed plate portion 9. As a result, the user U can place the back of his head on the main pillow 68 while his temporal region rests on the side pillow 39.
well supported by In addition, hydraulic cylinder 3
When the rod 30a is moved backward in the direction opposite to the arrow A, the roller 31 moves in the same direction and the moving rod 33 rotates in the opposite direction to the arrow B, separating from the rod 30a and returning to its original position. stand up in position. As a result, the upper end of the moving rod 33 moves upward, so that the second bed plate part 8 rotates in the direction opposite to the arrow E, and the third bed plate part 9 rotates in the direction opposite to the arrow F. Rotates and returns from the tilted use position to the original horizontal normal position. Along with this, the side pillow 39
The link 57 rotates in the opposite direction to the arrow I, and the receiving part 53 returns to the original horizontal state together with the stay 52, and the side head of the user U is separated from the side pillow 39, the weighted state is released, and the back of the head returns to its original state of being supported on the main pillow 68.

Furthermore, when the hydraulic cylinder 20 is driven, the moving rod 24 moves together with the roller 23 in the direction shown by arrow J in FIG. Accordingly, the fork-shaped moving rod 24 rotates about the pin 25 in the direction of arrow K in FIG. 2, receives the rod 20a, and overlaps the rod 20a integrally. As a result, as the portion where the pin 25 is located moves downward, the support rod 26 rotates about the pin 28 in the direction of arrow L and is positioned substantially in line with the movable rod 24. Then, since the portion where the pin 25 is located falls, the bed plate 7 first rotates in the direction of arrow M via the rod 14, and the second bed plate 8 rotates in the direction of the arrow M about the hinge mechanism 11. Rotate in the N direction and
The second bed plate parts 7 and 8 are bent downward at a substantially right angle with the hinge mechanism 10 as a boundary, and are displaced to the use position.

Accordingly, the user U shifts from a supine position on the second bed board 8 to a sideways position on the third bed board 9.

Further, as the bed plate portion moves from the normal position to the use position, the upright piece 46 of the side pillow 38 becomes inclined, so the link 49 rotates about the pin 51 in the direction of arrow O. Then, the stay 40 moves together with the receiving part 41 from the horizontal position to an inclined position parallel to the first bed plate part 7. As a result, when the user U moves from the supine position to the lying position, the side head of the user U is supported by the receiving part 41 of the side pillow 38 while the back of the head of the user U rests on the main pillow 68.

In addition, when returning the first and second bed plate parts 7 and 8 from the use position to the normal position, when the hydraulic cylinder 20 is driven, the rod 20a moves in the opposite direction to the arrow J, and the moving rod 24 moves. It rotates in the opposite direction to arrow K and stands up from the lying position. Along with this, the upper end of the moving rod 24 moves upward, so the first
The second bed plate parts 7 and 8 are rotated in the directions opposite to the arrows M and N through the pins 25, respectively, and return from the V-shaped recessed use position to the original horizontal normal position. .

Accordingly, the support rod 26 rotates in the opposite direction to the direction of the arrow L and returns from the position in line with the movable rod 24 to the original inclined position. At this time, the user U is placed from a sideways position on the first bed board 7 to a supine position on the second bed board 8.

Further, in the case of the side pillow 38, the upright piece 46 returns from the inclined state to the original vertical state, the link 49 rotates in the opposite direction to the arrow O, and the stay 40 moves to the receiving part 4.
1, the table returns to the original horizontal position from the tilted position parallel to the first bed plate part 7. Therefore, the side of the head of the user U moves away from the receiving part 41 of the side pillow 38, and the back of the head rests on the main pillow 68, returning to its original state.

According to the above configuration, the second and third bed plate parts, together with the first and second bed plate parts 7 and 8, are displaced between the horizontal normal position and the valley-shaped use position. Since it is provided so that the user U who is lying on his/her back can automatically change to the sideways state alternately from side to side. As a result, even if user U is bedridden and unable to move on his or her own,
This is extremely convenient as it allows the patient to turn over in bed without having to rely on the help of a caregiver or other attendant. This eliminates the fact that your weight is always on one spot, it is distributed well, and you can stay in a sideways position for a long time, which has the advantageous effect of eliminating the problem of side-slip.
There is no need to worry about the cost of nursing care over a long period of time, and the patient is able to maintain a peaceful state of rest without feeling the psychological pressure of having to be accompanied by someone. In addition, as the bed board moves from the normal position to the use position, it will slump to the left and right when turning over, so the mattress 66 will follow the bed board well and prevent the bed from shifting laterally. Not only that, but also,
A good sleeping condition can be obtained for the user U without creating a gap with the futon on the back side and the chest side.
Furthermore, as the user U moves from a supine position to a sideways position, the user can freely meet visitors on the left and right, which is convenient for viewing posters and television images.

It is also effective when the dorsal side is examined during hospital rounds.

Furthermore, when the second and third bed plate parts 8 and 9 are displaced from the normal position to the use position, the side pillows 39 move to an inclined state, so that the side pillows 39 of the user U's temporal region can be easily moved. The futon 66 is supported by the futon 66, and there is no unnecessary displacement of the futon 66, making it convenient to turn over in bed.
Furthermore, this realization requires only the use of links 57 and 49 having elongated holes 57a and 49a, which contributes to the simplification of the structure as well as cost.

In addition, the same thing can be said when the first and second bed plate parts 7 and 8 are displaced from the normal position to the use position, providing convenience when turning over.

In the above embodiment, the bed plate section is divided into three sections, but it is not limited to this number, and may be divided into four sections.

In addition, in the side pillows 38 and 39, as the bed plate portion is displaced from the normal position to the use position, the side pillow 3
When 8,39 changes from a horizontal state to an inclined state,
A toggle mechanism may be used instead of the links 57, 49.

Further, when the bed board parts move from the normal position to the use position, the angle formed is not limited to a right angle as in this embodiment, but can be changed as appropriate depending on the situation.

Further, in the above embodiment, the turnbuckle mechanism 29, T is used to telescopically adjust the length of the support rods 26, 35, but it is needless to say that the mechanism is not limited to this mechanism. For example, a rack and pinion mechanism may be used. Alternatively, the racks may be fixed to the support rods 26, 35, and the racks may be moved in the axial direction by the rotation of the pinion, so that the support rods 26, 35 can be displaced in the expansion/contraction direction. In this case, instead of manual operation, the pinion may be rotated by a motor to move the rack in an axially extending and contracting manner.

In addition, when the bed board moves from the normal position to the use position, each bed board is configured to be provided with a hinge mechanism in the center so that each bed board can be bent inward, albeit slightly. You may.

Furthermore, it can be used not only by sick people but also by healthy people if desired.

In addition, in the process of moving the bed plate section from the normal position to the use position, in the above embodiment, the moving rod 33 is rotated until it integrally overlaps the rod 30a of the hydraulic cylinder 30, but the rotation is You may make it stop suitably on the way. In this case, the rotational angular displacement of the moving rod 33 may be configured to be performed in a plurality of stages, such as two or three stages. Alternatively, the configuration may be such that the user U can selectively set an appropriate stage among the plurality of stages.

In addition, various changes may be made in the specific implementation without departing from the gist of the invention.
