Description

  The present invention relates to a supine table that can move a back bottom and a knee bottom up and down, respectively.

  A supine table called a Gatch bed allows the user to raise his back by raising the back bottom, and allows the user to raise his knee by raising the knee bottom. The body will shift to the leg side. Such a shift presses the user's lumbar spine and lower abdomen.

  For this reason, in Patent Document 1, when raising the back, the knee is also raised at the same time, that is, as shown in FIG. 4, the back bottom 31 is raised with the knee bottom 33 slightly raised, and then the knee bottom is raised. It has been proposed to raise 33 by lowering 33 so that the user's body is not displaced.

  However, when the knee bottom is raised, the body shifts to the head side, and when the back bottom is raised, the body shifts in the opposite direction.

The supine table according to the present invention is a back bottom for receiving a user's back, a knee bottom for receiving the knee portion of the user, a movable frame in which the back bottom and the knee bottom are arranged to be tiltable, A back bottom actuator and a knee bottom actuator for individually raising and lowering the back bottom and the knee bottom, and tilting the movable frame from a horizontal state, the back bottom side of the movable frame and the knee bottom side of the movable frame And a knee-side lifting actuator, and a control circuit for controlling the back-bottom actuator, the knee-bottom actuator, the back-side lifting actuator, and the knee-side lifting actuator And an operating device for instructing the control circuit, wherein the control circuit drives the back bottom actuator. When performing back lifting causing the back bottom and actuates the knee bottom actuator to perform a linked motion that causes the knee bottom, than the back bottom side knee bottom side of the movable frame of the movable frame in Rukoto a higher inclination to actuate at least one of the dorsal lift actuator and the knee-side lifting actuator to have said movable frame, performs the interlocking operation of changing the inclination of the movable frame, in this state, The knee bottom that is raised prevents the body from being displaced downward due to the raising of the back.After that, when the back bottom is further raised by driving the back bottom actuator, not end up giving tightness, the knee bottom actuator to perform the interlocking operation to defeat the knee bottom Performs control to dynamic, the operating machine, the carrying out the back lifting, an operation to cause the back bottom, the operation of changing the inclination of the operation and the movable frame to cause defeat the knee bottom, wherein the A feature is that an instruction to cancel the interlocking operation can be input .

  According to the present invention, the user's body displacement that occurs when raising and lowering the back bottom, such as raising and lowering the back, is inclined to cause a height difference between the back bottom side and the knee bottom side. This tilt can prevent the user from feeling new pressure and can perform appropriate back-up and back-down operations.

It is operation | movement explanatory drawing in an example of embodiment of this invention. (a) (b) is a block diagram which shows a schematic structure same as the above. It is operation | movement explanatory drawing which shows other operation | movement same as the above. It is operation | movement explanatory drawing of a prior art example.

  The present invention will be described in detail based on an example of the illustrated embodiment. In FIG. 2, reference numeral 1 denotes a base frame, and a movable frame 2 is attached to the base frame 1 via two bent links 11 and 12. ing. Each of the bending links 11 and 12 includes a motor-driven rotary actuator 4 at its node portion, and the movable frame 2 can be moved up and down with respect to the base frame 1 by driving the actuators 4 and 4. Further, the movable frame 2 can be tilted by the individual driving of the actuators 4 and 4.

  On the movable frame 2 located on the base frame 1, a back bottom 31, a waist bottom 32, a knee bottom 33, and a foot bottom 34 are arranged in this order. The back bottom 31 has an end on the knee bottom 33 side rotatably connected to the movable frame 2, and a motor driven telescopic actuator 5 is disposed between the back bottom 31 and the movable frame 2. The back bottom 31 rises around the rotation connecting point.

  While the waist bottom 32 is fixed to the movable frame 2, the knee bottom 33 is pivotally connected to the movable frame 2 at one end on the back bottom 31 side. A motor driven telescopic actuator 6 is arranged. One end of the foot bottom 34 on the knee bottom 33 side is rotatably connected to the end of the knee bottom 33 on the foot bottom 34 side. When the actuator 6 is extended, the knee bottom 33 rises while pulling the foot bottom 34.

Of the back bottom 31, waist bottom 32, knee bottom 33, and foot bottom 34 that will receive the user's body through a mattress (not shown), raising the back of the user by raising the back bottom 31. If the knee bottom 33 is raised, the user can be raised, and if the actuators 4 and 4 are further rotated, the movable frame 2 and the bottoms 31 to 34 can be moved up and down. In addition, by individually controlling the operations of the actuators 4 and 4, the movable frame 2 can be inclined to raise the user's head side or the foot side.

  The actuators 4, 4, 5, and 6 are under the control of the control circuit 7, and the control circuit 7 controls the actuators 4, 4, 5, and 6 in response to an input from the operating device 8 operated by the user. By operating, the above-mentioned back raising, knee raising, raising / lowering and tilting are performed.

  Here, the control circuit 7 not only drives the actuator 5 for the back bottom 31 but also the actuator 6 for the knee bottom 33 when the user or caregiver gives an instruction to raise the back by operating the operating device 8. And the actuators 4 and 4 for the movable frame 2 are also driven.

  That is, when there is an instruction to raise the back, the control circuit 7 first raises the knee bottom 33 slightly and drives the actuator 4 of the bending link 11 on the back bottom 31 side, as shown in FIG. The back bottom 31 side of the movable frame 2 is slightly raised. The body shift caused by raising the knee bottom 33 is eliminated by tilting the movable frame 2 together. Of course, the tilting of the movable frame 2 may be performed by lowering the knee bottom 33 and the foot bottom 34 side of the movable frame 2.

  Next, the control circuit 7 raises the back bottom 31 and at the same time raises the knee bottom 33 to prevent the body from being displaced downward when the back bottom 31 is raised. When the operation of raising the back bottom 31 is completed, the control circuit 7 returns the knee bottom 33 to the original position and also returns the movable frame 2 to the horizontal state.

  If there is an instruction from the operating device 8 to return the back bottom 31 to the horizontal state when the back is in the back-up state, the control circuit 7 first raises the knee bottom 33 slightly while raising the knee bottom 33 as shown in FIG. An operation of lowering the back bottom 31 side (or an operation of raising the knee bottom 33 and the foot bottom 34 side) is performed. Thereafter, the back bottom 31 is tilted down and the knee bottom 33 is returned to the original position, and finally the movable frame 2 is also returned to the horizontal state.

  The control circuit 7 prevents the movable frame 2 on which the back bottom 31 and the knee bottom 33 are placed from being tilted when the back bottom 31 is raised or the knee bottom 33 is raised. It is possible to appropriately prevent a shift of the body that could not be prevented by merely operating the knee bottom 33 and the knee bottom 33 in a coordinated manner.

  When the back bottom 31 is tilted with no user on the gatch bed, the knee bottom 33 and the movable frame 2 do not need to move in conjunction with each other. The user may feel that the interlocking operation is unnecessary. For this reason, the interlocking operation of the knee bottom 33 and the movable frame 2 at the time of raising and returning the back bottom 31 or the interlocking operation of the movable frame 2 at the time of knee lifting is canceled by the operation of the operating device 8. It is desirable to be able to do so.

  Further, it is desirable that the angle (the height difference between the back bottom 31 side and the knee bottom 33 side) by which the control circuit 7 tilts the movable frame 2 when raising the back and knees is made variable by setting with the operating device 8. .

In addition, when the movable frame 2 is in an inclined state, an instruction for an operation that causes the back bottom 31 to be tilted from the controller 8 or an instruction for an operation that causes the knee bottom 33 to be tilted is given. Or when there is an instruction to move the movable frame 2 up and down, the control circuit 7
In this example, the instructed operation is performed after the movable frame 2 is returned to the horizontal state.

  In addition, although the example which implement | achieved providing the inclination which makes the back bottom 31 side higher or lower than the knee bottom 33 side by providing the movable frame 2 was shown here, presence of the movable frame 2 is not essential. . As a mechanism for driving the back bottom 31 and the knee bottom 33 (and the foot bottom 34), a mechanism having an angle adjustment range in which the height position can be changed or the other end side can be made lower than the rotation fulcrum side. When using, the movement shown in FIG.1 and FIG.3 can be obtained by arrange | positioning each bottom 31-34 via the said mechanism on the base frame 1. FIG.
