Description

【0001】
【産業上の利用分野】
本発明は、被検体を支持し、上下動と旋回が可能な検診台に関する。
【0002】
【従来の技術】
一般に検診台は被検者を載せて上下に移動させたり、所定の位置まで旋回させたりするものであるから、検診台の動きを制御するために検診台と装置本体とがケーブルで、また電源等ともケーブルで接続されている。
【0003】
例えば、図5のように検診台は被検者を載せるための天板部51、上下動等の駆動信号や電源等の制御を行う制御部52、上下動支柱53、駆動部54、上下動支柱53の内側に設けられた旋回可能な固定支柱55、ベアリング部56、ベース57等で構成されている。
【0004】
ケーブルの接続方法としては、図5(a)のように装置本体、電源等からのケーブル58を床60の下を通し、ケーブル支柱59の内部を経て検診台の固定支柱55の下部へ導き、ここからケーブル58を貫通孔55Aから支柱内部を通して制御部52に接続する方法がある。ケーブル58は上下動支柱53とともに上下する制御部52に繋がっているので、検診台を旋回、上下させる場合、旋回、上下の動きを確保するためにあらかじめケーブル58に弛みをもたせている。
【0005】
また、図5(b)に示すようにあらかじめ所定長さのケーブルが収容できる大きさのピット61を床下に形成しておき、装置本体、電源等からのケーブル58をこのピット61から検診台の固定支柱55の内部を通して上下動支柱53の上部位置から制御部52に接続するようにしている。検診台が上方へ移動した場合にケーブルが引っ張られるので、その分ピット61のほうへケーブルを余分に収納している。
【0006】
【発明が解決しようとする課題】
しかし、図5(a)の従来例では、ケーブルに弛みをもたせ、外部に露出しているので、ケーブル自体が操作者の作業性を妨げる。また、ケーブルが血液や薬剤で汚れて不潔である。さらに、旋回角度を十分確保するためにはケーブルの弛みを長くしなければならないという問題があった。
【0007】
また、図5(b)の従来例では、上方移動によりケーブルが最大限引っ張られる長さの分だけ、余分なケーブルをピットに収容しておかなければならないのでピット容積が大きいものをつくらなければならず、据付可能な場所が制限されてしまう。さらに、ケーブル自体も支柱内で引っ張られたり、弛んだり、移動するのでケーブルに損傷が生じるという問題があった。
【0008】
本発明は、上記課題を解決するために創案されたもので、天板部を上下動や旋回させても、ケーブルが操作者の操作の妨げにならず、ケーブルが挟まれたりすり切れたりしないような検診台を提供するものである。
【0009】
【課題を解決するための手段】
上記目的を達成するために、本発明の検診台は、被検体を載置する天板部と、この天板部に取り付けられた中空の上下動支柱と、旋回可能な中空の固定支柱と駆動制御部とを備え、前記上下動支柱と固定支柱の一方が他方に内挿された2層構造で天板部を支持するように構成し、前記上下動支柱の一部に上下方向の切り欠き部を設けるとともに、駆動制御部を固定支柱側に設け、給電ケーブルを前記固定支柱の下側中央部から支柱内部を通して上部へ配設し、切り欠き部を通して駆動制御部に接続したことを特徴としている。
【0010】
【作用】
上下動支柱の切り欠き部の長さは天板部の上下動ストロークに応じて形成されているとともに、給電ケーブルは固定支柱の下側中央部から支柱内部を通し、前記固定支柱の上側にかけて配設されているので、上下動支柱が上下動を行ってもケーブルによってその動きが妨げられず、ケーブルに損傷を与えない。また、給電ケーブルはほぼ固定支柱の長さ分下へ垂れ下がっており、旋回による捩じれはその部分で吸収されるため、ケーブルに無理な力が加わらず、大きな角度で旋回させることができる。
【0011】
【実施例】
本発明の一実施例を、以下、図面に基づいて説明する。
【0012】
図1は本発明による検診台の縦断面図を示し、図2は横断面図を示している。1はベース、2はベアリング部、3は旋回可能な中空の固定支柱、4は固定支柱3の内側に配置された中空の上下動支柱、5a〜5dはコロ、6a、6bはレール、6cは溝形レール、7は天板部、8はケーブル、9はクランプ、10は上下動支柱4の上下方向に形成された切り欠き部、11は上下動支柱4の内部に形成された内壁、12は上下動等の駆動や電源の供給等の電気的な制御を行う駆動制御部、13は床に設けられたピット、14はモータ、15はモータプーリー、16はベルト、17は入力軸プーリー、18は減速機、19は出力軸ピニオンである。
【0013】
ベース1は床面に設置固定されており、検診台の駆動制御部12と本体装置や電源等とを接続するケーブル8を床下から導くためにピット13が形成されている。
【0014】
天板部7を支えている上下動支柱4の側面の一部には、上下方向に切り欠き部10が形成され、この部分の壁面は取り除かれている。他の側面にはレール6a〜6cが設けられている。
【0015】
また、固定支柱3の内側面にはコロ5a〜5eが、外側面には駆動制御部12が取り付けられており、この5a、5bのコロで上記のレール6aを、5c、5dのコロでレール6bを挟み込むようになっている。溝形レール6Cはその溝にコロ5eを噛み合わせるとともに、出力軸ピニオン19は溝形レール6Cの側面に形成された歯と噛み合っており、出力軸ピニオン19が回転すると、溝形レール6Cが上下に移動し、これにともなって、上下動支柱4が上下するようになるすなわち、モータ14が回転することによってモータプーリー15が回転し、この動力がベルト16によって入力軸プーリー17に伝えられ、減速機18を介して出力軸ピニオン19に動力が伝えられる。したがって、上下動支柱4の上下動はモータ15の正転、逆転によって行われる。
【0016】
また、図示はしていないが、ベアリング部2の部分には電磁ロック機構が取り付けられており、通常の状態では固定支柱3はロックされている。固定支柱3の旋回を行う場合には電気的に電磁ロックを解除して手動により天板部7を回転させる。
【0017】
一方、ケーブル8は上下動支柱4の下側から内空部を通り、切り欠き部10をを通し、固定支柱3の上部の一部を貫通させてここからケーブルを外へ導き、駆動制御部12へ接続される。ケーブル8はこの出口のところでクランプ9によって固定支柱3に固定される。
【0018】
ところで図3は、図1の状態から天板部7を180度旋回させ、かつ、上昇させた状態を示したものである。
【0019】
この図からもわかるように、上下動支柱4を上下動させると、クランプ9によって固定されたケーブルの固定部は切り欠き部10を相対的に移動するため、切り欠き部の長さL1が上下動ストロークとケーブルの太さとの和よりも長くしておけば、ケーブル8は上下動を妨げない。
【0020】
また、固定支柱3が旋回すれば、内部にある上下動支柱4と駆動制御部12も一体となって旋回するので、ケーブル8の上側と下側では捩じれが生じるが、この捩じれは図1のL2の範囲で発生するので、局部的に捩じれが集中することがなく、ケーブルに損傷を与えない。
【0021】
なお、内壁11は切り欠き部10を設けたことによる上下動支柱4の強度低下を補うものである。
【0022】
ところで、従来のように床に形成されるピットにはケーブルを所定の長さ収容しておく必要がなく、ケーブルの太さ程度のピットで済むので、床工事ができない部屋であっても図4のようにケーブル太さ程度のスペーサ20を設けることによって検診台を設置できる。
【0023】
また、固定支柱を内側、上下動支柱を外側に配置し、減速機やモータを固定支柱側に設け、駆動制御部をベース近くに設けて同様に構成することによって同様の効果が得られる。
【0024】
【発明の効果】
以上説明したように、本発明の検診台によれば、ケーブルが外へ露出しないので、操作の妨げとなることがなく、無理な力が加わらないので大きな旋回角度を取ることができ、ケーブルに損傷を与えることがない。また、ピットの容積も小さくて済むので、普通の部屋に設置することができる。

[Industrial applications]
The present invention relates to an examination table that supports a subject and can move up and down and turn.
[0002]
[Prior art]
In general, the examination table is used to move the patient up and down or rotate to a predetermined position with the patient placed thereon.Therefore, in order to control the movement of the examination table, the examination table and the main body of the apparatus are connected by a cable. And so on.
[0003]
For example, as shown in FIG. 5, the examination table includes a top plate 51 for placing a subject, a control unit 52 for controlling a driving signal such as vertical movement and a power supply, a vertical support column 53, a driving unit 54, and a vertical movement. It is composed of a rotatable fixed column 55 provided inside the column 53, a bearing portion 56, a base 57, and the like.
[0004]
As a method for connecting the cables, as shown in FIG. 5A, a cable 58 from the apparatus main body, a power supply, or the like passes under the floor 60, passes through the inside of the cable support 59, and is guided to the lower part of the fixed support 55 of the examination table. From here, there is a method of connecting the cable 58 to the control unit 52 from the through hole 55A through the inside of the column. Since the cable 58 is connected to the control unit 52 which moves up and down together with the up-and-down moving support 53, when the examination table is turned and moved up and down, the cable 58 is previously slackened to secure the turning and up-and-down movement.
[0005]
In addition, as shown in FIG. 5B, a pit 61 large enough to accommodate a cable of a predetermined length is formed under the floor in advance, and a cable 58 from the main body of the apparatus, a power supply, etc. is passed from the pit 61 to the inspection table. Through the inside of the fixed support column 55, a connection is made from the upper position of the vertically movable support column 53 to the control section 52. Since the cable is pulled when the examination table moves upward, the cable is stored extra toward the pit 61 accordingly.
[0006]
[Problems to be solved by the invention]
However, in the conventional example shown in FIG. 5A, the cable has slack and is exposed to the outside, so that the cable itself hinders the workability of the operator. Also, the cable is dirty with blood or chemicals. Further, there is a problem that the slack of the cable must be lengthened in order to secure a sufficient turning angle.
[0007]
In the conventional example shown in FIG. 5B, an extra cable must be stored in the pit by the length of the cable which is pulled to the maximum by the upward movement. In other words, the installation place is limited. Further, there is a problem that the cable itself is pulled, loosened, or moved in the column, so that the cable is damaged.
[0008]
The present invention has been conceived in order to solve the above-mentioned problem. Even if the top plate is moved up and down or turned, the cable does not hinder the operation of the operator, and the cable is not pinched or worn. Such a screening table is provided.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, the examination table of the present invention includes a top plate on which a subject is placed, a hollow vertical support column attached to the top plate unit, a hollow fixed support column that can rotate, and a drive. A control section, wherein one of the vertically movable column and the fixed column is configured to support the top plate in a two-layer structure inserted into the other, and a vertical cutout is formed in a part of the vertically movable column. And a drive control unit is provided on the fixed column side, and a power supply cable is disposed from the lower central portion of the fixed column to the upper portion through the inside of the column, and connected to the drive control unit through a cutout portion. I have.
[0010]
[Action]
The length of the notch of the vertical support is formed in accordance with the vertical stroke of the top plate, and the power supply cable is routed from the lower central part of the fixed support to the inside of the support and to the upper side of the fixed support. As a result, even if the up-and-down moving column moves up and down, the movement is not hindered by the cable and the cable is not damaged. In addition, since the power supply cable hangs down substantially by the length of the fixed column, and the torsion caused by the rotation is absorbed at that portion, the cable can be turned at a large angle without applying excessive force to the cable.
[0011]
【Example】
An embodiment of the present invention will be described below with reference to the drawings.
[0012]
FIG. 1 shows a longitudinal sectional view of the examination table according to the present invention, and FIG. 2 shows a transverse sectional view. 1 is a base, 2 is a bearing part, 3 is a rotatable hollow fixed support, 4 is a hollow vertical moving support arranged inside the fixed support 3, 5a to 5d are rollers, 6a and 6b are rails, 6c is A grooved rail, 7 is a top plate, 8 is a cable, 9 is a clamp, 10 is a cutout formed in the vertical direction of the vertical support 4, 11 is an inner wall formed inside the vertical support 4, 12. Is a drive control unit that performs electrical control such as driving such as vertical movement and power supply, 13 is a pit provided on the floor, 14 is a motor, 15 is a motor pulley, 16 is a belt, 17 is an input shaft pulley, 18 is a speed reducer, and 19 is an output shaft pinion.
[0013]
The base 1 is installed and fixed on the floor surface, and a pit 13 is formed to guide the cable 8 connecting the drive control unit 12 of the examination table to the main unit and power supply from under the floor.
[0014]
A notch 10 is formed in a part of a side surface of the vertically movable support column 4 supporting the top plate portion 7 in a vertical direction, and a wall surface of this portion is removed. Rails 6a to 6c are provided on other side surfaces.
[0015]
Rollers 5a to 5e are mounted on the inner surface of the fixed support 3, and a drive control unit 12 is mounted on the outer surface. The rails 6a are used with the 5a and 5b rollers, and the rails are used with the 5c and 5d rollers. 6b. The grooved rail 6C meshes with the roller 5e in the groove, and the output shaft pinion 19 meshes with teeth formed on the side surface of the grooved rail 6C. When the output shaft pinion 19 rotates, the grooved rail 6C moves up and down. In response, the vertical support column 4 moves up and down. That is, the rotation of the motor 14 rotates the motor pulley 15, and this power is transmitted to the input shaft pulley 17 by the belt 16, and the speed is reduced. Power is transmitted to the output shaft pinion 19 via the machine 18. Therefore, the vertical movement of the vertical support column 4 is performed by the forward and reverse rotations of the motor 15.
[0016]
Although not shown, an electromagnetic lock mechanism is attached to the bearing portion 2, and the fixed support 3 is locked in a normal state. When turning the fixed support 3, the electromagnetic lock is released electrically and the top plate 7 is manually rotated.
[0017]
On the other hand, the cable 8 passes from the lower side of the vertical support 4 through the inner space, passes through the notch 10, penetrates a part of the upper part of the fixed support 3, guides the cable from here, and drives the drive control unit. 12 is connected. The cable 8 is fixed to the fixed column 3 by a clamp 9 at this outlet.
[0018]
FIG. 3 shows a state in which the top plate 7 has been turned 180 degrees and raised from the state of FIG.
[0019]
As can be seen from this figure, when the vertical movement support 4 is moved up and down, the fixing portion of the cable fixed by the clamp 9 relatively moves the notch portion 10, so that the length L1 of the notch portion increases and decreases. If it is longer than the sum of the movement stroke and the thickness of the cable, the cable 8 does not hinder vertical movement.
[0020]
When the fixed support 3 rotates, the vertically movable support 4 and the drive control unit 12 inside rotate together, so that the upper and lower sides of the cable 8 are twisted. Since the twist is generated in the range of L2, the twist is not locally concentrated and the cable is not damaged.
[0021]
The inner wall 11 compensates for a decrease in the strength of the vertically movable column 4 due to the provision of the notch 10.
[0022]
By the way, it is not necessary to store a predetermined length of cable in a pit formed on the floor as in the related art, and a pit having a thickness approximately equal to that of the cable is sufficient. The examination table can be installed by providing the spacer 20 having a thickness of about the cable as shown in FIG.
[0023]
The same effect can be obtained by arranging the fixed support on the inner side and the vertically movable support on the outer side, providing the reduction gear and the motor on the fixed support, and providing the drive control unit near the base and having the same configuration.
[0024]
【The invention's effect】
As described above, according to the examination table of the present invention, since the cable is not exposed to the outside, it does not hinder the operation, and no excessive force is applied, so that a large turning angle can be obtained, and No damage. Further, since the pit volume can be small, it can be installed in a normal room.
