  In the present invention, the first and second receiving bases for receiving different parts of the body of the recumbent are provided so as to be able to rise and fall with respect to the base, and the first receiving stand is raised or lowered by the operation switch and the second The present invention relates to a reclining bed that enables a cooperating operation to raise and lower a cradle.

  Conventionally, reclining beds that can raise the back and thighs of lying people have been widely used as beds mainly used for hospitals and nursing care.

  In this reclining type bed, a back receiving base that receives the back of the lying person and a thigh receiving base that receives the thigh of the lying person are provided so as to be tiltable with respect to the base. And in a reclining type bed, a back part base and a thigh part base can be raised and lowered independently with respect to a base, respectively.

  Furthermore, in the conventional reclining type bed, in order to reduce the burden on the body of the lying person, it is possible to perform a cooperative operation for raising and lowering the thigh cradle together with the back cradle ( For example, see Patent Document 1.)

JP 2012-200470 A

  However, in the above-mentioned conventional reclining bed, for example, after performing a cooperative operation for raising and lowering the thigh cradle together with the back cradle, only the back cradle or the thigh cradle is tilted. In such a case, if the co-operation is performed again after that, the back cradle or the thigh cradle is in a state of being deviated from the predetermined tilting angle on the way. Therefore, it is necessary to return the back support and the thigh support to a predetermined tilt angle.

  Therefore, in the present invention according to claim 1, the first and second receiving bases for receiving different parts of the body of the recumbent are provided so as to be able to rise and fall with respect to the base, and the first receiving stand is raised by the operation switch. Alternatively, in a reclining bed that enables a cooperating operation to fall and tilt the second cradle, a plurality of combinations of the upright angles of the first and second cradles with respect to the base are provided in advance. When is operated, the first and second cradles are tilted at the standing angle of any combination, and then the cooperating operation is performed.

  According to a second aspect of the present invention, in the first aspect of the present invention, the operation switch includes a rising-side operation switch that performs a cooperating operation on the side on which the first cradle is raised, 1 with a lying side operation switch that performs a cooperative operation on the side where the cradle 1 is lying down, and when one of the operation switches is operated, depending on the operated switch on the standing side or the lying side Thus, the cooperative operation is performed after the first and second cradles are tilted at any one of the plurality of previously set upright angles.

  Further, in the present invention according to claim 3, in the present invention according to claim 2, when the operation switch on the standing side is operated, the first of the standing angles of the plurality of combinations provided in advance is selected. When the operation switch on the lying side is operated, the first cradle is set from the current state among the plurality of previously provided erection angles. Also decided to make the standing angle to fall down.

  Moreover, in this invention which concerns on Claim 4, in this invention which concerns on any one of the said Claims 1-3, the 1st drive part which drives the said 1st stand independently by predetermined operation | movement And a second drive unit that independently drives the second cradle by a predetermined operation, and when the operation switch is operated, the first and second drive units are respectively The first and second cradles are driven independently to perform the cooperative operation.

  And in this invention, there exists an effect described below.

  That is, in the present invention, the first and second receiving bases for receiving different parts of the lying person's body are provided so as to be able to rise and fall with respect to the base, and the first receiving stand is raised or laid down by the operation switch. In a reclining bed that enables a cooperating operation to raise and lower the two cradles, when a plurality of combinations of the upright angles of the first and second cradles with respect to the base are provided in advance and the operation switch is operated In this case, the first and second cradle is moved in the middle of the cooperating operation because the cooperating operation is performed after the first and second cradles are tilted at the standing angle of any combination. Even if it is tilted up and down, the cooperative operation can be smoothly performed again thereafter, and the feeling of use of the reclining bed can be improved.

  In particular, the operation switch includes an operation switch on the upright side that performs a cooperating operation on the side that erects the first cradle, and an operation on the lying side that performs a cooperating operation on the side on which the first cradle is overlaid. And when any one of the operation switches is operated, the first and any of the plurality of combinations of the rising angles provided in advance according to the operated operation switch on the standing side or the lying side are operated. When it is decided to perform the cooperating operation after raising the second cradle, the cooperating operation can be smoothly resumed regardless of whether the operation switch on the standing side or the lying side is operated. This can further improve the feeling of use of the reclining bed.

  Further, when the operation switch on the standing side is operated, among the plurality of previously set up standing angles, the standing angle is set to raise the first cradle from the current state, and the operation on the lying side is performed. When the switch is operated, the standing side or the lying side is determined when the standing angle is set so that the first cradle falls more than the current level among the standing angles of the plurality of combinations provided in advance. Even when any of these operation switches is operated, the cooperating operation can be smoothly resumed according to the operated operation switch, and this can further improve the feeling of use of the reclining bed.

  Furthermore, a first drive unit that independently drives the first cradle by a predetermined operation, and a second drive unit that independently drives the second cradle by a predetermined operation. And when the operation switch is operated, the first and second drive units independently drive the first and second cradles to perform a cooperative operation. In this case, the control and mechanism for the first drive unit and the second drive unit can be simplified, and the cost of the reclining bed can be reduced.

  The lower body cradle 6 mainly receives the load of the lying person's thigh (supports the lying person's thigh from below) and mainly receives the load of the lying person's lower leg (the lying person) The lower leg support 10 is used to support the lower leg from below.

  The lower body cradle 6 pivotally attaches the rear end of the thigh cradle 9 to the front side of the bottom part cradle 4 of the base 2 so as to be rotatable up and down. Thereby, the thigh cradle 9 can be raised and lowered with respect to the base 2 and the buttocks cradle 4. Further, the lower body cradle 6 is pivotally attached to the front end of the thigh cradle 9 so that the rear end of the crus cradle 10 can be pivoted up and down. As a result, the crus cradle 10 is tilted with the thigh cradle 9 with respect to the base 2 and the buttocks cradle 4 and can be tilted with respect to the thigh cradle 9 (freely Bendable). The lower leg support 10 is configured such that the rear end moves together with the front end of the thigh support 9 and the front end moves along the upper surface of the base 2.

  Drive units 11, 12, and 13 are connected to the back receiving base 7, the shoulder receiving base 8, and the thigh receiving base 9 for independently raising and lowering each. These drive units 11, 12, and 13 are connected to the control unit 14 and are driven and controlled according to a program stored in the control unit 14. Here, the drive units 11, 12, and 13 are connected to the back receiving unit 7, the shoulder receiving unit 8, and the thigh receiving unit 9, respectively. However, the present invention is not limited to this. The back receiving base 7, the shoulder receiving base 8, and the thigh receiving base 9 may be driven by the link mechanism, and the back receiving base 7 and the shoulder receiving base may be configured by one driving part and the link mechanism. You may comprise so that the stand 8, the back part receiving base 7, and the thigh receiving part 9 may be driven, and the remaining thigh receiving part 9 and the shoulder receiving part 8 may be driven by another driving part. Moreover, the drive parts 11, 12, and 13 should just be a mechanism which can drive in the direction which makes the back part base 7, the shoulder part base 8, and the thigh part base 9 stand up or lie down, for example, can advance and retreat to an electric motor Each cylinder 7, 8 and 9 can be raised and lowered by interlocking and connecting the appropriate cylinders and moving the cylinders back and forth with an electric motor.

  The control unit 14 is connected to the operation unit 15 and various sensors (for example, a sensor that detects the standing angle of each of the cradles 7, 8, and 9). The operation unit 15 includes an operation switch 16 for standing the back cradle 7 alone, an operation switch 17 for causing the back cradle 7 to stand alone, and a shoulder cradle 8 for standing alone. An operation switch 18, an operation switch 19 for tilting the shoulder cradle 8 alone, an operation switch 20 for standing the thigh cradle 9 alone, and a femoral cradle 9 alone And an operation switch 21. Further, the operating portion 15 is provided with the back receiving base 7, the shoulder receiving base 8 and the thigh receiving base by raising the back receiving base 7 and raising and lowering the shoulder receiving base 8 and the thigh receiving base 9. The operation switch 22 on the standing side for operating together (cooperating operation) 9 and the back receiving base 7 are laid down and the shoulder receiving base 8 and the thigh receiving base 9 are tilted up and down. There is a lying-side operation switch 23 for operating the back receiving base 7, the shoulder receiving base 8 and the thigh receiving base 9 together (operating operation).

  When the control unit 14 detects that each of the operation switches 16 to 21 has been operated, the control unit 14 drives and controls one of the drive units 11, 12, and 13 according to the operated operation switches 16 to 21, The cradle 7, the shoulder cradle 8, and the thigh cradle 9 are each driven in the direction of standing or lying down.

  Further, the control unit 14 drives and controls the drive units 11, 12, and 13 to raise the back receiving base 7 when detecting that the operation switch 22 on the standing side that performs the cooperating operation is operated. And the shoulder cradle 8 and the thigh cradle 9 are driven in the direction of standing or lying down, and the back cradle 7, the shoulder cradle 8 and the thigh cradle 9 are operated together. To do. On the other hand, when the control unit 14 detects that the operation switch 23 on the lying side that performs the cooperating operation is operated, the drive unit 11, 12, 13 is driven and controlled so as to lie down on the back receiving base 7. And the shoulder cradle 8 and the thigh cradle 9 are driven in the direction of standing or lying down, and the back cradle 7, the shoulder cradle 8 and the thigh cradle 9 are operated together. To do.

  Here, the cooperative movement refers to an action in which the cradle (the back cradle 7, the shoulder cradle 8, and the thigh cradle 9) that receives different parts of the recumbent's body rises and falls in relation to each other. The back receiving base 7, the shoulder receiving base 8 and the thigh receiving base 9 are not limited to those that rise and fall in relation to each other, but the back receiving base 7 and the shoulder receiving base 8 rise and fall in relation to each other. It may be a thing, and the back part base 7 and the thigh part base 9 may be tilted in relation to each other. In addition, the cooperative operation is not limited to that the cradle that rises and falls in association with the control unit 14 according to a predetermined linkage pattern, and each of the cradles that rise and fall in relation is determined in advance. May be operated independently.

  In the following description, for easy understanding, the back receiving base 7 (first receiving base) and the thigh receiving base 9 (second receiving base) are respectively connected to the respective driving units 11 (first driving). Part) and the drive part 13 (second drive part) are driven independently in accordance with a predetermined operation pattern, and the back support 7 and the thigh support 9 are caused to rise and fall in relation to each other. A case of performing the operation will be described.

  As shown in FIG. 2 (a), the drive unit 11 for driving the back receiving base 7 has a back portion depending on the total operation time in which the operation switch 22 on the standing side is operated from the state in which the back receiving base 7 is horizontal. The control unit 14 controls the cradle 7 to stand. The drive unit 11 raises and lowers the back receiving base 7 by moving the cylinder linked to the electric motor forward and backward. The control unit 14 controls the voltage applied to the electric motor of the drive unit 11 to change the rotation speed of the electric motor per unit time, and accordingly, change the forward / backward movement distance per unit time of the cylinder. The raising / lowering speed of the back support 7 is changed. Here, in the state where a recumbent with a predetermined average physique (height, total weight, upper body load, lower body load, etc.) is lying, the standing angle of the back cradle 7 between the operation time of 0 and T2 ( (The angle with respect to the base 2 and the butt support 4) changes from 0 to θ2, and the standing angle of the back support 7 changes from θ2 to θ4 during the operation time from T2 to T4, and the operation time from T4 The angle is changed from θ4 to θ5 until T5. In addition, the inclination in the figure is the raising / lowering speed of the back receiving base 7. Further, when the operation switch 23 on the lying down side is operated, control is performed so as to operate in the direction opposite to the above depending on the operation time.

  On the other hand, as shown in FIG. 2 (b), the drive unit 13 for driving the thigh cradle 9 is operated with the operation switch 22 on the upright side from the state where the thigh cradle 9 is horizontal. The thigh cradle 9 is controlled by the control unit 14 so as to stand up according to the total operation time. The drive unit 13 raises and lowers the thigh cradle 9 by moving the cylinder linked to the electric motor back and forth. The control unit 14 controls the voltage applied to the electric motor of the drive unit 13 to change the rotation speed of the electric motor per unit time, and accordingly, change the forward / backward movement distance per unit time of the cylinder. Thus, the raising / lowering speed of the thigh cradle 9 is changed. Here, in the state in which a recumbent with a predetermined average physique (height, total weight, upper body load, lower body load, etc.) is lying, the thigh cradle 9 is erected between an operation time of 0 and T1. The angle (angle with respect to the base 2 and the butt support 4) changes from 0 to φ1, and the standing angle of the thigh support 9 changes from φ1 to φ3 during the operation time from T1 to T3. The time is changed from φ3 to 0 between T3 and T5. In addition, the inclination in the figure is the raising / lowering speed of the thigh cradle 9. Further, when the operation switch 23 on the lying down side is operated, control is performed so as to operate in the direction opposite to the above depending on the operation time.

  The control unit 14 separately controls the drive unit 11 of the back cradle 7 and the drive unit 13 of the thigh cradle 9 and independently controls the back cradle 7 and the thigh independently of the drive units 11 and 13. Raise the cradle 9. Then, in a state where a recumbent with a predetermined average physique is lying down, the back receiving base 7 and the thigh receiving base 9 perform a cooperative operation in association with each other as shown by a one-dot chain line in FIG. However, the cooperative operation of the back cradle 7 and the thigh cradle 9 indicated by the alternate long and short dash line in FIG. 3 is merely a state in which a recumbent with an average physique determined in advance is lying down. Actually, the height, overall weight, upper body load, lower body load and other physiques of the recumbent differ greatly from person to person. For example, as shown by the solid line in FIG. Will co-operate.

  As described above, the control unit 14 controls the back part pedestal 7 and the thigh cradle 9 to be independently driven by a predetermined action by the respective drive parts 11 and 13 so as to perform the cooperative operation. In this case, the cooperative movement of the back receiving base 7 and the thigh receiving base 9 deviates from the ideal cooperative movement (the operation indicated by the one-dot chain line in FIG. 3) depending on the actual size of the lying person. Although there is a fear, the configuration of the drive units 11 and 13 and the control by the control unit 14 become easy, the reclining bed 1 can be stably operated, and the cost of the reclining bed 1 can be reduced. it can.

  In contrast to this, the control unit 14 uses the interlocking pattern that always passes through the coordinates of the rising angle of the back receiving base 7 and the rising angle of the thigh receiving base 9 that are set in advance in advance. When controlling the control units 11 and 13 to perform the cooperating operation, the cooperating operation can be performed along a certain interlocking pattern regardless of the physique of the lying person, but the driving units 11 and 13 There is a risk that the configuration and control by the control unit 14 may be complicated, which may cause malfunction and cost increase of the reclining bed.

  In addition, even in the case of co-operating along a certain interlocking pattern, when only the back receiving base 7 or only the thigh receiving base 9 are tilted up and down like the reclining bed 1, A shift in co-operation occurs.

  For this reason, the reclining bed 1 is configured to return to a desired cooperating operation when a shift in the cooperating operation occurs.

  First, in the reclining bed 1, as shown in FIG. 4, a combination of standing angles of the back receiving base 7 and the thigh receiving base 9 with respect to the base 2 as a point to be restored in advance (indicated by “•” in FIG. 4). Are provided and stored in the control unit 14. The return point may be a combination of standing angles of the back cradle 7 and the thigh cradle 9 (combination on the line indicated by a one-dot chain line in FIG. 3) that passes during a normal cooperative operation. A different combination may be used.

  In the reclining bed 1, when the operation switches 22, 23 on the standing side or the lying side are operated, the control unit 14 drives the driving units 11, 13 to store any combination of the standing angles stored in advance. Then, the back receiving base 7 and the thigh receiving base 9 (the back receiving base 7 and / or the thigh receiving base 9) are raised and lowered (returned).

  Thereafter, as shown in FIGS. 2 (a) and 2 (b), the reclining bed 1 causes the control unit 14 to drive the drive units 11 and 13, respectively, so that the back receiving base 7 and the thigh receiving base 9 work together. Control to work.

  The combination to be restored may be any of a plurality of combinations stored in advance.

  For example, as shown in FIG. 5, when one of the operation switches 22 and 23 on the standing side or the lying side is operated, the same combination is restored regardless of which operation switch 22 or 23 is operated. Also good. In this case, among the plurality of combinations, a combination that can return the back support 7 and the thigh support 9 in the shortest time (current combination (indicated by x in FIG. 5)) and a combination that returns. It is also possible to return to the combination in which the distance in FIG. 5 is the shortest (indicated by solid arrows in FIG. 5). Or you may make it return to the combination which the back part stand 7 can return in the shortest time among several combinations (it shows with the dashed-dotted arrow in FIG. 5). In addition, you may make it return to the combination which can return the thigh receiving stand 9 in the shortest time among several combinations. In the above description, both the back receiving base 7 and the thigh receiving base 9 are raised, but either one or both of the back receiving base 7 and the thigh receiving base 9 have already returned. When the standing angle is set, the back receiving base 7 and the thigh receiving base 9 do not need to be tilted. The same applies to the following description.

  Further, when any of the operation switches 22 and 23 on the standing side or the lying side is operated, it may be returned to a different combination depending on the operation switches 22 and 23 on the standing side or the lying side operated. . In this case, when the operation switch 22 on the standing side is operated, the combination that can return in the shortest time from the combinations that raise the back receiving base 7 (the combination on the right side of the dotted line in FIG. 5). When returning (indicated by a solid arrow in FIG. 5) and the operation switch 23 on the lying side is operated, from among the combinations (the combination on the left side of the dotted line in FIG. 5) that causes the back receiving base 7 to fall down You may make it return to the combination which can be returned in the shortest time (it shows with the dashed-two dotted line arrow in FIG. 5). Alternatively, when the operation switch 22 on the standing side is operated, the back receiving base 7 is returned in the shortest time among the combinations that raise the back receiving base 7 (the combination on the right side of the dotted line in FIG. 5). Return to the combination that can be used (indicated by a one-dot chain line arrow in FIG. 5), and when the operation switch 23 on the lying side is operated, the combination that causes the back support 7 to fall (left side of the dotted line in FIG. 5) The back support 7 may be returned to a combination that can be returned in the shortest time (indicated by a two-dot chain line arrow in FIG. 5). When the operation switch 22 on the standing side is operated, the thigh cradle 9 is returned to the combination that can return the thigh cradle 9 in the shortest time from among the combinations that erect the thigh cradle 9 and lying down. When the operation switch 23 on the side is operated, the thigh cradle 9 may be returned to the combination that can return the thigh cradle 9 in the shortest time from among the combinations that lie down. .

  When returning the back receiving base 7 and the thigh receiving base 9, the back receiving base 7 and the thigh receiving base 9 are not limited to the case where the back receiving base 7 and the thigh receiving base 9 are simultaneously tilted and returned. Only the cradle 9 may be returned first, or the back cradle 7 and the thigh cradle 9 may be raised and lowered gradually.

  Moreover, the timing which returns the back part receiving base 7 or the thigh receiving part 9 detected that the control part 14 raised only the back receiving part 7 or the thigh receiving part 9 in the middle of the cooperative action. It may be made to return when any of the operation switches 22 and 23 for performing the cooperating operation later is operated, or cooperating after the control unit 14 detects the current combination and determines that the cooperating operation is necessary. It may be restored when any of the operation switches 22 and 23 for performing the operation is operated, and is always restored when any of the operation switches 22 and 23 for performing the cooperating operation is operated. You may do it.

  As described above, the reclining bed 1 is based on the first cradle (back cradle 7) and the second cradle (thigh cradle 9) that receive different parts of the body of the lying person. It is provided so that it can be tilted with respect to the base 2, and the first base (back base 7) is raised or lowered by the operation switches 22 and 23 and the second base (thigh base 9) is tilted up and down. It enables the cooperating action to be performed. In the reclining bed 1, the first cradle is the back cradle 7 and the second cradle is the thigh cradle 9.
