Description

本発明は、背ボトムと膝ボトムとを夫々上下させることができる仰臥台に関するものである。   The present invention relates to a supine table that can move a back bottom and a knee bottom up and down, respectively.

ギャッチベッドと称される仰臥台は、背ボトムを起こすことで利用者の背上げを可能とし、膝ボトムを起こすことで利用者の膝上げを可能としているが、背ボトムを起こした時、利用者の身体が脚側にずれてしまう。このようなずれは、利用者の腰椎や下腹部を圧迫することになる。   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.

このために、特許文献1には背上げを行う時には同時に膝上げも行うことで、つまりは図4に示すように、膝ボトム33を少しあげた状態で背ボトム31を起こし、その後、膝ボトム33を下げることで背上げを行って、利用者の身体にずれが生じないようにすることが提案されている。   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.

しかしながら、膝ボトムを起こした時点で身体が頭側にずれ、背ボトムを起こすことで身体が逆方向にずれてしまうものであり、腰椎や下腹部の圧迫感を取り除くには不十分である。   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, which is insufficient to remove the feeling of pressure on the lumbar spine and lower abdomen.

特開2004−000557号公報JP 2004-000557 A

本発明は上記問題に鑑みてなされたもので、背上げに伴う身体のずれがなくて身体に圧迫感を与えてしまうことがない仰臥台を提供することを課題とする。   This invention is made | formed in view of the said problem, and makes it a subject to provide the supine stand which does not give the feeling of pressure to a body without the shift | offset | difference of the body accompanying back raising.

本発明にかかる仰臥台は、利用者の背中を受ける背ボトムと、前記利用者の膝部分を受ける膝ボトムと、前記背ボトムと前記膝ボトムとが起倒自在に配される可動フレームと、前記背ボトム及び前記膝ボトムを個別に起倒させる背ボトム用アクチュエータ及び膝ボトム用アクチュエータと、前記可動フレームを水平状態から傾かせて、前記可動フレームの背ボトム側と前記可動フレームの膝ボトム側とに高低差を生じさせる背側昇降用アクチュエータ及び膝側昇降用アクチュエータと、前記背ボトム用アクチュエータ、前記膝ボトム用アクチュエータ、前記背側昇降用アクチュエータ及び前記膝側昇降用アクチュエータを制御する制御回路と、前記制御回路に指示を行う操作機とを備え、前記制御回路は、前記背ボトム用アクチュエータを駆動して前記背ボトムを起こして背上げを行うにあたり、前記膝ボトムを起こすように前記膝ボトム用アクチュエータを作動させ、前記可動フレームの背ボトム側が前記可動フレームの膝ボトム側よりも高くなる傾きを前記可動フレームが持つように前記背側昇降用アクチュエータ及び前記膝側昇降用アクチュエータの少なくとも一方を作動させ、この状態で、起こされた前記膝ボトムによって背上げに伴う身体の下方側へのずれが防止され、その後、前記背ボトム用アクチュエータを駆動して前記背ボトムを更に起こして背上げを行う際には、身体に圧迫感を与えてしまうことがないよう、前記膝ボトムを倒すように前記膝ボトム用アクチュエータを作動させる制御を行うものであり、前記操作機は、前記背ボトムを起こす動作と、前記膝ボトムを起倒させる動作及び前記可動フレームの傾きを変える動作と、の連動動作をキャンセルする機能を備えることに特徴を有している。   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 raising the back bottom and raising the back, the knee bottom actuator is actuated to raise the knee bottom, and the back bottom side of the movable frame is inclined higher than the knee bottom side of the movable frame. Actuate at least one of the back-side lifting actuator and the knee-side lifting actuator so that the movable frame has, and in this state, the raised knee bottom causes the body to move downward due to the raising of the back. After that, when driving the back bottom actuator to raise the back bottom and raising the back, the knee bottom is tilted so as not to give the body a feeling of pressure. The actuator controls the actuator for the knee bottom, and the operating device is configured to raise the back bottom and the knee bolt. It is characterized in further comprising an act of changing the inclination of the operation and the movable frame to defeat cause the beam, a function of canceling the interlocking operation.

本発明によれば、背上げや背下げ等の背ボトムを起倒する際に生じる利用者の身体のずれを、背ボトム側と膝ボトム側との間に高低差が生じる傾きを持たせることで防止することができるものであり、このような傾きは利用者に新たな圧迫感を与えるようなこともなく、適切な背上げや背下げ動作を行うことができる。   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.

本発明を図示の実施の形態の一例に基づいて詳述すると、図2において、1はベースフレームであり、このベースフレーム1には2つの屈曲リンク11,12を介して可動フレーム2が取り付けられている。各屈曲リンク11,12は、その節点部にモータ駆動の回転型アクチュエータ4を備えており、これらアクチュエータ4,4の駆動により、ベースフレーム1に対して可動フレーム2を昇降させることができる。また、アクチュエータ4,4の個別駆動により、可動フレーム2を傾斜させることができる。   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.

上記ベースフレーム1上に位置する可動フレーム2上には、背ボトム31と腰ボトム32と膝ボトム33そして足ボトム34が順に配されている。背ボトム31はその膝ボトム33側の端部が可動フレーム2に回動自在に連結されているとともに、可動フレーム2との間にモータ駆動の伸縮型アクチュエータ5が配されたもので、アクチュエータ5を伸張させることにより、背ボトム31は上記回動連結点を中心に起きあがる。   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.

腰ボトム32は可動フレーム2に固定されているのに対して、膝ボトム33はその背ボトム31側の一端が可動フレーム2に回動自在に連結されているとともに、可動フレーム2との間にモータ駆動の伸縮型アクチュエータ6が配されている。そして足ボトム34はその膝ボトム33側の一端が膝ボトム33の足ボトム34側の端部に回動自在に連結されている。アクチュエータ6を伸張させれば、膝ボトム33が足ボトム34を引き寄せつつ起きあがる。   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.

マットレス(図示せず)を介して使用者の身体を受けることになる上記背ボトム31と腰ボトム32と膝ボトム33と足ボトム34のうち、背ボトム31を起こせば、使用者の
背上げを行うことができ、膝ボトム33を起こせば使用者の膝上げを行うことができ、さらにアクチュエータ4,4を回動させれば、可動フレーム2及び各ボトム31〜34を昇降させることができる。また、アクチュエータ4,4の動作を個別に制御することで、可動フレーム2に利用者の頭側を高くする、あるいは足側を高くする傾きを持たせることができる。
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.

上記の各アクチュエータ4,4,5,6は、制御回路7の制御下にあり、使用者が操作する操作機8からの入力に応じて制御回路7が各アクチュエータ4,4,5,6を作動させることで、上記背上げや膝上げ、昇降、傾斜を行う。   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.

ここにおいて、上記制御回路7は、利用者あるいは介護者が操作機8の操作で背上げの指示を行った時、背ボトム31用のアクチュエータ5の駆動だけでなく、膝ボトム33用のアクチュエータ6の駆動及び可動フレーム2用のアクチュエータ4,4の駆動も行う。   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.

すなわち、上記制御回路7は、背上げの指示があった時、図1に示すように、まず、膝ボトム33を少し起こすとともに、背ボトム31側にある屈曲リンク11のアクチュエータ4を駆動して可動フレーム2の背ボトム31側を少し高くする。膝ボトム33を起こすことによって生じる身体のずれを可動フレーム2ごと傾けることで解消する。なお、可動フレーム2を傾斜させることは、可動フレーム2の膝ボトム33及び足ボトム34側を下げることで行ってもよいのはもちろんである。   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.

次いで、上記制御回路7は、背ボトム31を起こすと同時に膝ボトム33を更に起こすことで、背ボトム31を起こす際の身体の下方側へのずれを防止する。そして、背ボトム31を起こす動作が完了すれば、制御回路7は膝ボトム33を元に戻すとともに、可動フレーム2も水平状態に戻す。   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.

背上げ状態にある時に、操作機8から背ボトム31を水平状態に戻す指示があれば、制御回路7は、図3に示すように、まず、膝ボトム33を少し上げつつ、可動フレーム2の背ボトム31側を下げる動作(あるいは膝ボトム33及び足ボトム34側を上げる動作)を行わせる。その後、背ボトム31を倒していき、膝ボトム33も元に戻す動作を行い、最終的には可動フレーム2も水平状態に戻す。   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.

背ボトム31を起こしたり膝ボトム33を起こしたりする際の身体のずれを、制御回路7がこれら背ボトム31や膝ボトム33を載せた可動フレーム2を傾けることで防ぐものであり、背ボトム31と膝ボトム33とを協調動作させるだけでは防ぐことができなかった身体のずれを、適切に防ぐことができる。   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.

ギャッチベッド上に利用者がいない状態で背ボトム31を起倒させる時には、膝ボトム33や可動フレーム2が連動して動く必要はない。利用者自身が連動動作を不要と感ずることもある。このために、上記背ボトム31を起こす背上げやその復帰の際の膝ボトム33及び可動フレーム2の連動動作、あるいは膝上げの時の可動フレーム2の連動動作は、操作機8の操作でキャンセルできるようにしておくことが望ましい。   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.

また、背上げや膝上げを行うにあたって制御回路7が可動フレーム2を傾かせる角度(背ボトム31側と膝ボトム33側との高低差)は、操作機8による設定で可変としておくことが望ましい。   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. .

また、可動フレーム2が傾いた状態にある時に、操作機8から背ボトム31を起倒させることになる動作の指示があったり、膝ボトム33を起倒させることになる動作の指示があったり、あるいは可動フレーム2を昇降させる動作の指示があった時には、制御回路7
は、可動フレーム2を水平状態に戻した後に、指示された動作を実行するものとしている。
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.

なお、ここでは背ボトム31側を膝ボトム33側よりも高くあるいは低くする傾きを持たせることを、可動フレーム2を設けることで実現した例を示したが、可動フレーム2の存在は必須ではない。背ボトム31や膝ボトム33(及び足ボトム34)を駆動する機構として、その高さ位置を変更したり、回動支点側よりも他端側を低くすることができる角度調節範囲を有するものを用いる場合、ベースフレーム1上に上記機構を介して各ボトム31〜34を配置することで、図1及び図3に示した動きを得ることができる。   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.
