However, in the above-mentioned conventional reclining bed, for example, after performing a collaborative operation of tilting the thigh pedestal together with the back pedestal halfway, only the back pedestal or the thigh pedestal is tilted. In such a case, if the collaborative motion is performed again after that, the back pedestal or the thigh pedestal is in a state of being deviated from the predetermined tilt angle on the way, and the subsequent collaborative motion is performed as it is. It is necessary to return the back pedestal and the thigh pedestal to a predetermined tilt angle so that the operation cannot be performed normally.

Therefore, in the present invention according to claim 1, a first pedestal for receiving the back of the lying person and a second pedestal for receiving the thighs of the lying person are provided so as to be able to be tilted with respect to the base, and the operation switch is used. In a reclining bed that enables a collaborative operation in which the first pedestal is erected or laid down and the second pedestal is erected, a plurality of combinations of the standing angles of the first and second pedestals with respect to the base are previously provided. The first and second pedestals are set at the standing angle of the combination that can move the first and / or the second pedestal in the shortest time from any combination when the operation switch is operated. I decided to make them move together after raising them.

It has an operation switch on the lodging side that causes the pedestal of 1 to perform a synergistic operation, and when any of the operation switches is operated, it corresponds to the operation switch on the standing side or the lying side that is operated. The first and / or second pedestals were tilted to one of the standing angles of the combination capable of moving the first and / or the second pedestal in the shortest time from the plurality of combinations provided in advance. Later, I decided to have them perform a collaborative operation.

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 standing angle of the plurality of combinations provided in advance is the first. When the pedestal of No. 1 is set to an upright angle to stand up from the current state and the operation switch on the lodging side is operated, the first pedestal is set to the upright angle of a plurality of combinations provided in advance from the current state. I decided to set the standing angle to lie down.

Further, in the present invention according to claim 4, in the present invention according to any one of claims 1 to 3, the first drive unit that independently drives the first pedestal by a predetermined operation. And a second drive unit that independently drives the second pedestal by a predetermined operation, and when the operation switch is operated, the first and second drive units, respectively. It was decided to independently drive the first and second pedestals to perform the cooperative operation.

Then, in the present invention, the effects described below are obtained.

That is, in the present invention, the first and second pedestals that receive different parts of the body of the reclining person are provided so as to be able to fold up and down with respect to the base, and the first pedestal is erected or laid down by the operation switch. When a plurality of combinations of standing angles of the first and second pedestals with respect to the pedestal are provided in advance in a reclining bed capable of collaborative operation of tilting the pedestal of 2 and the operation switch is operated. Since it is decided that the first and second pedestals are tilted to the standing angle of either combination and then the collaborative operation is performed, the first or second pedestal is performed in the middle of the collaborative operation. Even if only the reclining bed is raised, the collaborative movement can be smoothly performed again after that, and the usability of the reclining bed can be improved.

In particular, the operation switch is an operation switch on the standing side that causes the side that raises the first pedestal to perform a collaborative operation, and an operation on the lodging side that causes the side that causes the first pedestal to lie down. It has a switch, and when any of the operation switches is operated, the first and the first and the standing angles of the plurality of combinations provided in advance are set according to the operated upright side or downside operation switch. If it is decided to perform the collaborative operation after tilting the second pedestal, the collaborative operation can be smoothly restarted regardless of whether the operation switch on the upright side or the prone side is operated. It is possible to further improve the usability of the reclining bed.

Further, when the operation switch on the upright side is operated, the upright angle is set so that the first pedestal stands up more than the current state among the upright angles of the plurality of combinations provided in advance, and the operation on the downside side is performed. When the switch is operated, if the standing angle of the first pedestal is set to be a standing angle that causes the first pedestal to lie down more than the current state among the standing angles of the plurality of combinations provided in advance, the standing side or the laying side Regardless of which of the operation switches is operated, the collaborative operation can be smoothly restarted according to the operated operation switch, which can further improve the usability of the reclining bed.

Further, a first driving unit that independently drives the first pedestal by a predetermined operation and a second driving unit that independently drives the second pedestal by a predetermined operation are provided. When the operation switch is operated, the first and second drive units independently drive the first and second pedestals to perform a co-operation 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.

On the other hand, when the control unit 14 detects that the operation switch 23 on the lodging side that performs the collaborative operation is operated, the control unit 14 drives and controls the driving units 11, 12, and 13 to lie down the back pedestal 7. The shoulder pedestal 8 and the thigh pedestal 9 are driven in a direction of standing up or lying down, and the back pedestal 7, the shoulder pedestal 8 and the thigh pedestal 9 act in concert with each other. To do.

Here, the synergistic movement refers to a movement in which the pedestals (back pedestal 7, shoulder pedestal 8, thigh pedestal 9) that receive different parts of the body of the lying person are tilted in relation to each other. , The back pedestal 7 and the shoulder pedestal 8 and the thigh pedestal 9 are not limited to all related and tilted, and the back pedestal 7 and the shoulder pedestal 8 are related and tilted. It may be one in which the back pedestal 7 and the thigh pedestal 9 are related to each other and are raised or lowered. Further, the collaborative operation is not limited to the one in which the pedestals to be tilted in relation to each other are interlocked by the control unit 14 according to a predetermined interlocking pattern, and the pedestals to be tilted in relation to each other are respectively predetermined operation patterns. It may be operated independently by.

In the following description, for ease of understanding, the back pedestal 7 (first pedestal) and the thigh pedestal 9 (second pedestal) are respectively driven by the drive unit 11 (first drive). The back pedestal 7 and the thigh pedestal 9 move up and down in relation to each other by independently driving the back pedestal 7 and the thigh pedestal 9 in a predetermined operation pattern by the driving unit 13 (second driving unit). The case of performing the operation will be described.

As shown in FIG. 2A, the drive unit 11 for driving the back pedestal 7 has a back portion according to the total operation time when the operation switch 22 on the standing side is operated from the state where the back pedestal 7 is horizontal. The control unit 14 controls the cradle 7 so as to stand upright. The drive unit 11 raises and lowers the back cradle 7 by moving the cylinder linked to the electric motor in an advancing and retreating manner. The control unit 14 changes the rotation speed of the electric motor per unit time by controlling the voltage applied to the electric motor of the drive unit 11, and changes the advancing / retreating movement distance of the cylinder per unit time accordingly. The tilting speed of the back cradle 7 is changed. Here, in a state where a lying person with a predetermined average physique (height, total weight, upper body load, lower body load, etc.) is lying down, the operating time is between 0 and T2, and the standing angle of the back cradle 7 ( The angle with respect to the base 2 and the buttock pedestal 4) changes from 0 to θ2, the standing angle of the back pedestal 7 changes from θ2 to θ4 while the operation time is from T2 to T4, and the operation time changes from T4. It is designed to change from θ4 to θ5 between T5 and T5. The inclination in the figure is the tilting speed of the back cradle 7. Further, when the operation switch 23 on the lodging side is operated, it is controlled to operate in the opposite direction to the above depending on the operation time.

On the other hand, in the drive unit 13 for driving the thigh pedestal 9, as shown in FIG. 2B, the operation switch 22 on the standing side was operated from the state where the thigh pedestal 9 was horizontal. The control unit 14 controls the thigh pedestal 9 to stand up according to the total operation time. The drive unit 13 raises and lowers the thigh pedestal 9 by moving the cylinder linked to the electric motor in an advancing and retreating manner. The control unit 14 changes the rotation speed of the electric motor per unit time by controlling the voltage applied to the electric motor of the drive unit 13, and changes the advancing / retreating movement distance of the cylinder per unit time accordingly. The tilting speed of the thigh pedestal 9 is changed. Here, the thigh pedestal 9 stands up while the operation time is from 0 to T1 in a state where a lying person with a predetermined average physique (height, total weight, upper body load, lower body load, etc.) is lying down. The angle (angle with respect to the base 2 and the buttock pedestal 4) changes from 0 to φ1, and the standing angle of the thigh pedestal 9 changes from φ1 to φ3 during the operation time from T1 to T3. The time is set to change from φ3 to 0 between T3 and T5. The inclination in the figure is the tilting speed of the thigh pedestal 9. Further, when the operation switch 23 on the lodging side is operated, it is controlled to operate in the opposite direction to the above depending on the operation time.

The control unit 14 separately controls the drive unit 11 of the back pedestal 7 and the drive unit 13 of the thigh pedestal 9, and the back pedestal 7 and the thigh are independently controlled by the drive units 11 and 13. The club cradle 9 is raised and lowered. Then, in a state in which a person lying down with a predetermined average physique lies down, the back pedestal 7 and the thigh pedestal 9 perform a synergistic operation in relation to each other as shown by the alternate long and short dash line in FIG. However, the collaborative movement of the back pedestal 7 and the thigh pedestal 9 shown by the alternate long and short dash line in FIG. 3 is merely a state in which a person lying down with a predetermined average physique is lying down. Actually, the height, total weight, upper body load, lower body load, and other physiques of the lying person differ greatly from person to person. Therefore, for example, as shown by the solid line in FIG. Will work together.

In this way, the control unit 14 controls the back pedestal 7 and the thigh pedestal 9 so that the back pedestals 7 and the thigh pedestals 9 are independently driven by the respective drive units 11 and 13, so that the co-operation operation is performed. In some cases, the collaborative motion of the back pedestal 7 and the thigh pedestal 9 deviates from the ideal collaborative motion (the motion shown by the alternate long and short dash line in FIG. 3) depending on the actual physique of the reclining person. Although there is a risk, the configuration of the drive units 11 and 13 and the control by the control unit 14 can be facilitated, the reclining bed 1 can be operated stably, and the cost of the reclining bed 1 can be reduced. it can.

On the other hand, the coordinates consisting of the standing angle of the back pedestal 7 and the standing angle of the thigh pedestal 9 are set in advance in detail, and the control unit 14 uses an interlocking pattern that always passes through the coordinates. When the control units 11 and 13 are controlled to perform the co-operation operation, the co-operation operation can be performed according to a certain interlocking pattern regardless of the physique of the reclining person. The configuration of the reclining bed and the control by the control unit 14 may be complicated, which may cause a malfunction of the reclining bed and an increase in cost.

Further, even when the beds are moved together according to a certain interlocking pattern, when only the back pedestal 7 and the thigh pedestal 9 are independently raised and lowered as in the reclining bed 1, when the back pedestal 7 and the thigh pedestal 9 are independently raised and lowered. There is a shift in the collaborative movement.

Therefore, in the reclining bed 1, when a deviation of the co-operation operation occurs, the reclining operation is restored to a desired co-operation operation.

First, in the reclining bed 1, as shown in FIG. 4, the combination of the standing angles of the back pedestal 7 and the thigh pedestal 9 with respect to the base 2 as a point of returning in advance (indicated by · in FIG. 4). Are provided and stored in the control unit 14. The returning point may be a combination of the standing angles of the back pedestal 7 and the thigh pedestal 9 that pass during the normal collaborative operation (combination on the line shown by the alternate long and short dash line in FIG. 3). , A different combination may be used.

Then, in the reclining bed 1, when the operation switches 22 and 23 on the upright side or the downside side are operated, the control unit 14 drives the drive units 11 and 13, respectively, and the upright angle of any combination stored in advance is stored. The back pedestal 7 and the thigh pedestal 9 (back pedestal 7 and / or thigh pedestal 9) are raised (returned) so as to be.

After that, in the reclining bed 1, as shown in FIGS. 2A and 2B, the control unit 14 drives the drive units 11 and 13, respectively, and the back pedestal 7 and the thigh pedestal 9 cooperate with each other. 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 any of the operation switches 22 and 23 on the upright side or the downside side is operated, the same combination is restored regardless of which operation switches 22 and 23 are operated. May be good. In this case, among the plurality of combinations, the combination that can return the back pedestal 7 and the thigh pedestal 9 in the shortest time (the current combination (indicated by x in FIG. 5) and the combination that returns). It may be possible to return to the combination (the combination in which the distance is the shortest in FIG. 5) (indicated by a solid arrow in FIG. 5). Alternatively, the back pedestal 7 may be restored to the combination that can be restored in the shortest time from among the plurality of combinations (indicated by the alternate long and short dash arrow in FIG. 5). It should be noted that the thigh pedestal 9 may be restored to the combination that can be restored in the shortest time from among the plurality of combinations. Further, in the above description, both the back pedestal 7 and the thigh pedestal 9 are erected, but one or both of the back pedestal 7 and the thigh pedestal 9 have already returned. When the standing angle is set, the back pedestal 7 and the thigh pedestal 9 do not have to be tilted. This also applies to the following description.

Further, when any of the operation switches 22 and 23 on the upright side or the downside side is operated, the combination may be returned to a different combination depending on the operation switches 22 and 23 on the upright side or the downside side that have been operated. .. In this case, when the operation switch 22 on the standing side is operated, the combination that allows the back pedestal 7 to stand up (the combination on the right side of the dotted line in FIG. 5) can be restored in the shortest time. When the operation switch 23 on the lodging side is operated after returning (indicated by a solid arrow in FIG. 5), the back cradle 7 is tilted (the combination on the left side of the dotted line in FIG. 5). It may be possible to return to the combination that can be returned in the shortest time (indicated by the alternate long and short dash arrow in FIG. 5). Alternatively, when the operation switch 22 on the standing side is operated, the back pedestal 7 is returned in the shortest time from the combinations for raising the back pedestal 7 (the combination on the right side of the dotted line in FIG. 5). When the combination that can be used is restored (indicated by the alternate long and short dash line arrow in FIG. 5) and the operation switch 23 on the lodging side is operated, the back cradle 7 is tilted (on the left side of the dotted line in FIG. 5). The back pedestal 7 may be returned to the combination that can be returned in the shortest time (indicated by the alternate long and short dash line arrow in FIG. 5). When the operation switch 22 on the standing side is operated, the thigh pedestal 9 is returned to the combination that can be returned in the shortest time from the combination of standing the thigh pedestal 9, and the thigh pedestal 9 is laid down. When the operation switch 23 on the side is operated, the thigh pedestal 9 may be returned to the combination that can be returned in the shortest time from the combination in which the thigh pedestal 9 is laid down. ..

When returning the back pedestal 7 or the thigh pedestal 9, the back pedestal 7 or the thigh pedestal 7 or the thigh is not limited to the case where the back pedestal 7 and the thigh pedestal 9 are simultaneously tilted and returned. Only the pedestal 9 may be returned first, or the back pedestal 7 and the thigh pedestal 9 may be tilted to gradually return.

Further, at the timing of returning the back pedestal 7 and the thigh pedestal 9, it was detected that only the back pedestal 7 or the thigh pedestal 9 was tilted down during the co-operation of the control unit 14. It may be set to return when any of the operation switches 22 and 23 for performing the co-operation operation later is operated, or the control unit 14 detects the current combination and determines that the co-operation is necessary, and then the co-operation is performed. It may be set to return when any of the operation switches 22 and 23 for performing the operation is operated, and further, it is always returned when any of the operation switches 22 and 23 for performing the collaborative operation is operated. You may do so.

As described above, the reclining bed 1 is based on a first pedestal (back pedestal 7) and a second pedestal (thigh pedestal 9) that receive different parts of the body of a lying person. The first pedestal (back pedestal 7) is erected or laid down by the operation switches 22 and 23, and the second pedestal (thigh pedestal 9) is laid down. It enables the collaborative movement to make it.
