JP, 2006-340962, A

In the conventional body support device described above, since the drive unit also rotates with the rotation of the rotation unit, it is necessary to secure a large clearance around the drive unit.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to facilitate downsizing of a body support device.

In order to solve the above problems, the present invention proposes the following means.
(1) The body support device according to the present invention includes a base portion that receives a load of a user, a rotation portion that is fixed to the base portion so as to be rotatable about a rotation axis, and the rotation portion that is fixed to the base portion. And a wire member extending from the drive unit toward the rotating unit and fixed to the rotating unit. The driving unit pulls the wire member to rotate the wire. It is characterized in that the part is rotated.

In this case, the drive unit rotates the rotating unit by pulling the wire rod. Therefore, it is not necessary to rotate the drive unit along with the rotation of the rotation unit, and it is possible to facilitate downsizing of the body support device. Further, it is possible to suppress interference between the drive unit and other members due to the rotation of the drive unit. Further, it is possible to suppress the loss of the driving force and make it easier to stabilize the output.

(2) In the body supporting device according to (1) above, the rotating portion may include a fan-shaped winding member.

In this case, the rotating portion includes a fan-shaped winding member. Therefore, by winding the wire rod around the winding member and fixing a part of the wire rod to the winding member, when the drive unit pulls the wire rod, the driving force of the drive unit is applied from the wire rod to the winding member (rotating unit). ), the wire wound around the winding member is gradually unwound to shorten its length, and the rotating portion can be rotated around the rotation axis.

(3) In the body supporting device according to (2), the rotating portion further includes a shaft member extending in the rotating shaft direction, and the winding member intersects the rotating shaft from the shaft member. You may employ|adopt the structure which protrudes in the direction.

In this case, the rotating portion includes the shaft member and the winding member. Therefore, for example, when adjusting the winding diameter of the wire rod according to the configuration of the applied base, etc., by changing the outer diameter of the winding member while adopting a common configuration for the shaft member, Can be adjusted. This makes it possible to diversify the application range of the body supporting device.

(4) In the body supporting device according to (2) or (3), the wire rod serves as a contact point from the winding start point of the wire rod in the winding member toward the drive unit. A configuration may be adopted in which the winding member extends in the tangential direction of the winding member and the drive unit pulls the wire rod in the tangential direction from the winding start point.

In this case, when the drive unit rotates the rotating unit, the drive unit pulls the wire rod tangentially from the winding start point. Then, the rotating portion rotates like a constant pulley with the rotating shaft as the fulcrum and the winding start point as the force point. At this time, since the distance between the fulcrum (rotating shaft) and the power point (winding start point) is kept equal, the loss of the driving force can be suppressed.

In the body support device according to (4), an intermediate portion of the wire rod located between the drive unit and the winding member is wound, and the intermediate portion is wound from the drive unit to the winding member. A pulley for guiding the member may be further provided, and the pulley may be fixed to the base portion so as to be rotatable about a guide shaft extending in a direction orthogonal to the rotation axis direction and the tangential direction. Good.

In this case, the pulley is fixed to the base so as to be rotatable around the guide shaft. Accordingly, for example, it is not necessary to make the drive unit and the winding member face each other in the tangential direction, and the drive unit and the winding member can be displaced in the rotation axis direction. Further, for example, it is not necessary to extend the wire material in a straight line between the drive unit and the winding member, and when the other member is located between the drive unit and the winding member, the member may be bypassed. Wires can be routed to. As a result, the degree of freedom in design can be increased.

Further, in the body supporting device according to the above (1) to (4), a configuration is provided in which the support portion that supports the user is provided, and the rotating portion is the support portion, or the support portion is moved. You may.

In this case, a large load from the user acts on the support portion. Therefore, the rotating part is such a supporting part, or by moving such a supporting part, the effect of being able to suppress the loss of the driving force as described above is remarkably achieved. You can

According to the present invention, the body support device can be easily downsized.

Each panel member 16 is formed in a long plate shape extending in the left-right direction, and the front and back surfaces of each panel member 16 face the vertical direction. A plurality of panel members 16 are arranged side by side in the front-rear direction. Each panel member 16 has an equivalent position in both the up-down direction and the left-right direction in a standard state before the bed 11 is deformed by the drive mechanism 14 such as raising the back or raising the knee, for example, being rotated with undulations. Are arranged on the same plane.

Each upper surface of the plurality of panel members 16 forms a bed surface 15. The bed surface 15 is an orthogonal surface orthogonal to the vertical direction in the standard state described above. The bed surface 15 is formed in a rectangular shape that is longer in the front-back direction than in the left-right direction in plan view. The longitudinal direction of the bed surface 15 is the front-back direction, and the lateral direction of the bed surface 15 is the left-right direction. A mattress (not shown) is arranged on the bed surface 15.

The plurality of panel members 16 are divided into a plurality of groups in the front-rear direction. The plurality of panel members 16 are grouped in the order of a back bottom 18 and a leg bottom 19 from the head side H toward the leg side F. Further, the leg bottoms 19 are grouped in the order of a knee bottom 20 and a foot bottom 21 from the head side H to the leg side F. The back bottom 18 corresponds to the back on the bed surface 15, and the leg bottom 19 corresponds to the waist to the feet on the bed surface 15. The knee bottom 20 corresponds to the waist to the knee on the bed surface 15, and the foot bottom 21 corresponds to the knee to the foot on the bed surface 15.

The base frame 27 is placed on the installation floor and has a rectangular shape in plan view.

The main frame 28 has a rectangular frame shape in a plan view. The main frame 28 (the gantry body 24) is smaller than the bed 11 (the bed surface 15) in the left-right direction. The bed 11 projects from the main frame 28 on both sides in the left-right direction. The main frame 28 can support the left and right ends of the bed 11 from below.

As shown in FIGS. 2 and 3, the elevating and lowering connecting mechanism 29 connects the base frame 27 and the main frame 28, and supports the main frame 28 so that the main frame 28 can be moved up and down. The up-and-down connecting mechanism 29 has a so-called X-link structure.

As shown in FIG. 1, the first rotation mechanism 25 rotatably holds the back bottom 18 via the first shaft member. The first rotating mechanism 25 tilts the back bottom 18 with respect to the horizontal plane while raising and lowering the head side H of the back bottom 18 by rotating the back bottom 18 up and down around the first shaft member. As the first rotation mechanism 25, a known back raising mechanism (retra mechanism) can be adopted.

As shown in FIGS. 1 and 4, the second rotation mechanism 26 rotatably holds the leg bottom 19 via the second shaft member 23. The second rotation mechanism 26 rotates the leg bottom 19 about the second shaft member 23 so that the portion of the leg bottom 19 located between the knee bottom 20 and the foot bottom 21 faces upward. The leg bottom 19 is bent so as to form a protrusion. At this time, the end of the leg bottom F of the leg bottom 21 moves to the head side H on the gantry body 24 in a state where the end of the knee bottom 20 on the head side H is fixed in the front-rear direction.

As shown in FIG. 4, the second rotating mechanism 26 includes a connecting member 39, a movable member 40, a fixing member 34, and a mounting member 41. The panel member 16 forming the leg bottom 19 is connected to the connecting member 39. The connecting member 39 integrally connects the plurality of panel members 16. The connecting member 39 is connected to the lower surface of each panel member 16. The connecting members 39 extend in the front-rear direction and are arranged in a pair in the left-right direction with a space therebetween.

Each connecting member 39 is divided into two parts in the front-rear direction into a head-side division part 42 and a leg-side division part 43. The panel member 16 forming the knee bottom 20 is connected to the head side divided portion 42, and the panel member 16 forming the foot bottom 21 is connected to the leg side divided portion 43. The head-side divided portion 42 and the leg-side divided portion 43 are rotatably connected via a bending shaft portion 44 extending in the left-right direction.

The movable member 40 is connected to the leg bottom 19 via a connecting member 39. The movable member 40 is located on the head side H with respect to the connecting member 39. The end of the connecting member 39 on the head side H is connected to the movable member 40. The end of the connecting member 39 on the leg side F is a free end.

The fixing member 34 is connected to the gantry body 24. The fixing member 34 extends linearly in the left-right direction and crosses the main frame 28 in the left-right direction.
The attachment member 41 is connected to the gantry body 24, and in the present embodiment, is connected to the gantry body 24 via the fixing member 34. The mounting member 41 projects from the fixing member 34 toward the leg side F. A pair of mounting members 41 are arranged at intervals in the left-right direction. The mounting member 41 is connected to the movable member 40 via the second shaft member 23. The second shaft members 23 are arranged in a pair on the left and right sides and coaxially.

As shown in FIG. 1, in the support pedestal 12, the back bottom 18 is connected to the gantry body 24 via the first rotating mechanism 25, and the leg bottom 19 is attached to the gantry body 24 via the second rotating mechanism 26. It is connected. The first rotation mechanism 25 and the second rotation mechanism 26 rotate the back bottom 18 and the leg bottom 19 from the above-described standard state, so that the bed 11 is backed as shown by a two-dot chain line in FIG. It is in a typical state of use in which the legs are raised and the legs are raised (knees are raised). When the bed 11 is changed from the standard state to the use state, the legs are raised before the back is raised, so that the shift of the user with respect to the bed apparatus 10 can be effectively prevented.

The board 13 is fixed to the support base 12 and stands up above the bed surface 15. A pair of front and rear boards 13 are provided, and stand up from both ends of the gantry body 24 in the front-rear direction.

The drive mechanism 14 rotates each of the back bottom 18 and the leg bottom 19 (movable bottom). As shown in FIGS. 4 and 5, the drive mechanism 14 includes a first drive mechanism (not shown) that rotates the back bottom 18, and a second drive mechanism 45 that rotates the leg bottom 19. The first drive mechanism is arranged below the back bottom 18, and the second drive mechanism 45 is arranged below the leg bottom 19. A known back-raising drive mechanism can be used as the first drive mechanism.

The second driving mechanism 45 includes a rotating portion 46, a driving portion 47, and a wire rod 48.
The rotating portion 46 moves the leg bottom 19. The rotating portion 46 rotates the leg bottom 19 about the second shaft member 23. The rotating portion 46 is fixed to the gantry body 24 so as to be rotatable around the rotation axis L. The rotation axis L is a virtual axis extending in the left-right direction, and the rotation axis L direction is parallel to the left-right direction. The rotating portion 46 includes a shaft member 51, a winding member 52, and a push-up member 53. The shaft member 51 extends in the left-right direction (direction of the rotation axis L). The shaft member 51 is connected to the main frame 28 so as to be rotatable around the rotation axis L.

The winding member 52 and the push-up member 53 project from the shaft member 51 in a direction intersecting the rotation axis L. The winding member 52 and the push-up member 53 project toward the opposite side in the front-rear direction with the shaft member 51 interposed therebetween. The winding member 52 projects from the shaft member 51 toward the head side H, and the push-up member 53 projects from the shaft member 51 toward the leg side F. The winding member 52 is formed in a plate shape whose front and back surfaces are oriented in the left-right direction. The winding member 52 is connected to the central portion of the shaft member 51 in the left-right direction.

The winding member 52 has a fan shape when the rotating portion 46 is laterally viewed from the left-right direction. In the side view, the winding member 52 has a fan shape with a central angle of 90 degrees. The winding member 52 includes a first straight line portion 54, a second straight line portion 55, and an arc portion 56. The first straight line portion 54, the second straight line portion 55, and the arc portion 56 form the peripheral edge portion of the winding member 52 in the side view.

The first straight line portion 54 and the second straight line portion 55 correspond to the radius of the sector, and the circular arc portion 56 corresponds to the circular arc of the sector. The first straight line portion 54 and the second straight line portion 55 intersect with each other. The intersection of the first straight line portion 54 and the second straight line portion 55 corresponds to the center of the sector and is fixed to the shaft member 51 so as not to rotate. The first straight portion 54 extends from the shaft member 51 toward the head side H along the front-rear direction. The second straight portion 55 extends downward from the shaft member 51 along the vertical direction. The second straight line portion 55 extends parallel to the vertical direction. The lower end edge (outer edge in the radial direction) of the second linear portion 55 is located directly below the shaft member 51. The circular arc portion 56 is formed with a circumferential groove 57 extending over the entire length thereof. The radius of the sector may be, for example, 50 mm to 100 mm, and more specifically, about 80 mm.

The push-up member 53 pushes up the leg bottom 19 via the connecting member 39. The push-up member 53 extends in the front-rear direction along the lower surface of the leg bottom 19. The push-up member 53 extends from the shaft member 51 toward the leg side F. A pair of left and right push-up members 53 are provided. The push-up members 53 are provided at both ends of the shaft member 51 in the left-right direction. The leg-side F end of the push-up member 53 slidably contacts the lower surface of the head-side divided portion 42.

The drive unit 47 is fixed to the gantry body 24 and rotates the rotating unit 46. The drive portion 47 is immovably fixed to the end portion of the main frame 28 on the leg side F. The drive unit 47 linearly moves based on power supplied from the outside, that is, electric power in the illustrated example. For the drive unit 47, for example, a so-called linear actuator or the like can be adopted. The drive unit 47 linearly expands and contracts in the front-rear direction based on the power. The drive unit 47 faces the winding member 52 in the front-rear direction. The drive unit 47 is arranged at the same position as the winding member 52 in the left-right direction.

The wire 48 extends from the drive unit 47 toward the rotating unit 46 and is fixed to the rotating unit 46. The wire rod 48 is wound around the rotation unit 46 around the rotation axis L. For the wire rod 48, a member that is easily deformable to the extent that it can be wound around the rotating portion 46 can be adopted. As the wire material 48, for example, a wire or a chain can be adopted. The wire 48 is wound around the winding member 52. The wound wire rod 48 is fixed to the winding member 52 at a fixed portion 48a described later.

The wire 48 extends from the drive portion 47 toward the head side H in parallel in the front-rear direction, and then is wound around the winding member 52 from the lower end edge of the second straight portion 55 toward the upper side along the arc portion 56. ing. The position of the wire rod 48 in the left-right direction is the same over the entire length of the wire rod 48. The head-side H end of the wire 48 is fixed to the head-side H end of the first straight portion 54 in a non-separable manner. This end portion is the fixed portion 48a fixed to the winding member 52. A portion of the wire rod 48 along the arc portion 56 is detachably fitted into the circumferential groove 57.

The winding start point P of the wire 48 on the winding member 52 is located at the lower end edge of the second linear portion 55. The intermediate portion 48b of the wire 48, which is located between the drive unit 47 and the winding member 52, is wound from the winding start point P toward the drive unit 47 at the winding start point P as a contact point. It extends in the tangential direction of the rotating part 46). In the illustrated example, the intermediate portion 48b extends tangentially over its entire length. The tangential direction is parallel to the front-back direction.

Then, the drive unit 47 pulls the wire rod 48 to rotate the rotating unit 46. The drive unit 47 pulls the wire 48 in the tangential direction from the winding start point P (rotating unit 46). When the drive unit 47 pulls the wire rod 48 in the tangential direction from the rotating unit 46, the driving force of the drive unit 47 is transmitted from the fixed portion 48a of the wire member 48 to the rotating unit 46. Then, as shown in FIG. 6, the wire rod 48 wound around the winding member 52 is gradually unwound and the length thereof is shortened, while the rotating portion 46 is rotated around the rotation axis L. Then, the turning portion 46 turns like a constant pulley with the turning axis L as the fulcrum and the winding start point P of the wire 48 with respect to the turning portion 46 as the force point. At this time, the distance between the fulcrum (rotation axis L) and the power point (winding start point P) is kept equal, and the loss of the driving force is suppressed.

In the present embodiment, when the rotating portion 46 rotates about the rotation axis L, the end of the push-up member 53 on the leg side F slides on the lower surface of the connecting member 39 and pushes up the knee bottom 20. Then, as shown by the chain double-dashed line in FIG. 1, the knee bottom 20 rotates about the second shaft member 23, and the end of the knee bottom 20 on the leg side F rises. At this time, the foot bottom 21 relatively rotates about the bending shaft portion 44, and the portion corresponding to the knee on the bed surface 15 bends so as to project upward, which is a so-called leg-up state.

As described above, according to the bed device 10 according to the present embodiment, the drive unit 47 rotates the rotating unit 46 by pulling the wire rod 48. Therefore, it is not necessary to rotate the drive unit 47 in accordance with the rotation of the rotation unit 46, and it is possible to easily reduce the size of the bed apparatus 10 (for example, lower the floor). Further, it is possible to suppress the interference between the drive unit 47 and other members due to the rotation of the drive unit 47. Further, it is possible to suppress the loss of driving force and make it easier to stabilize the output.
A large load from the user acts on the bed 11. Therefore, as the rotating unit 46 moves the bed 11 as described above, it is possible to remarkably achieve the action and effect obtained by suppressing the loss of the driving force as described above.

The rotating portion 46 includes a shaft member 51 and a winding member 52. Therefore, for example, when the winding diameter of the wire 48 is adjusted according to the configuration of the gantry body 24 to be applied, the shaft member 51 should have a common configuration while changing the outer diameter of the winding member 52. Thus, the winding diameter can be adjusted. This makes it possible to diversify the applicable range of the bed apparatus 10.

(Second embodiment)
Next, a bed apparatus 60 according to a second embodiment of the present invention will be described with reference to FIGS. 7 and 8.
In the second embodiment, the same components as those in the first embodiment are designated by the same reference numerals, the description thereof will be omitted, and only different points will be described.

In the bed apparatus 60 of the present embodiment, first, the drive unit 47 is arranged so as to be displaced in the left-right direction with respect to the winding member 52. Hereinafter, the direction in which the drive unit 47 is located along the left-right direction with respect to the winding member 52 is referred to as one side of the left-right direction. The direction in which the winding member 52 is positioned along the left-right direction with respect to the drive unit 47 is referred to as the other side in the left-right direction.
The second drive mechanism 45 (bed apparatus 60) further includes a pulley 61. The intermediate portion 48b of the wire 48 is wound around the pulley 61, and the intermediate portion 48b is guided from the drive unit 47 to the winding member 52.

The pulley 61 is rotatably fixed to the gantry body 24 around a guide axis O extending in the up-down direction (a direction orthogonal to the rotation axis direction and the tangential direction). The gantry body 24 includes a support plate 62 fixed to the main frame 28. The support plate 62 is arranged inside the main frame 28. The front and back surfaces of the support plate 62 face up and down. The pulley 61 is fixed to the upper surface of the support plate 62.

Two pulleys 61 are provided. The pulleys 61 are arranged so as to be displaced in the front-rear direction and the left-right direction. The pulley 61 includes a first pulley 61a on the drive unit 47 side and a second pulley 61b on the winding member 52 side. The first pulley 61a is located on one side in the left-right direction with respect to the second pulley 61b and on the leg side F in the front-rear direction. The first pulley 61a is located on the other side in the left-right direction with respect to the drive unit 47 and on the head side H in the front-rear direction. The second pulley 61b is located on one side in the left-right direction with respect to the winding member 52 and on the leg side F in the front-rear direction.

The intermediate portion 48b of the wire 48 extends in the front-rear direction from the drive unit 47 and is first wound around the outer peripheral surface of the first pulley 61a. At this time, the extending direction of the intermediate portion 48b changes from the front-rear direction to the left-right direction. Then, the intermediate portion 48b is wound around the outer peripheral surface of the second pulley 61b. At this time, the extending direction of the intermediate portion 48b changes from the left-right direction to the front-back direction. Then, the intermediate portion 48b reaches the winding member 52. The intermediate portion 48b extends from the winding start point P in the tangential direction described above.

In the bed device 60, the drive unit 47 pulls the end of the wire 48 on the drive unit 47 side in the front-back direction. Then, while the intermediate portion 48b of the wire 48 rotates each pulley 61, the entire intermediate portion 48b is pulled to the drive unit 47 side. As a result, the drive unit 47 pulls the wire rod 48 tangentially from the winding start point P.

As described above, according to the bed apparatus 60 according to the present embodiment, the pulley 61 is fixed to the gantry body 24 so as to be rotatable around the guide axis O. Thereby, for example, it is not necessary to make the drive unit 47 and the winding member 52 face each other in the tangential direction, and the drive unit 47 and the winding member 52 can be laterally displaced. Further, for example, it is not necessary to extend the wire rod 48 in a straight line between the drive unit 47 and the winding member 52, and when another member is positioned between the drive unit 47 and the winding member 52, The wire 48 can be wired so as to bypass the member. As a result, the degree of freedom in design can be increased.

There is. In the side view, the winding member 52 has a right-angled isosceles triangular shape. The winding member 52 includes the first straight line portion 54 and the second straight line portion 55 described above, and the hypotenuse portion 71. The first straight line portion 54, the second straight line portion 55, and the hypotenuse portion 71 form the peripheral edge portion of the winding member 52 in the side view. The hypotenuse portion 71 corresponds to the hypotenuse of the isosceles right triangle.
