Description

身体支持装置及びベッド装置Body support device and bed device
　複数の可動部を有する身体支持装置等に関する。 It relates to a body support device having a plurality of movable parts.
　従来から、ベッド装置や椅子といった身体支持装置は、複数の可動部を有しており、それぞれを動かすことにより、患者や介護者の身体をより適切に支える構成となっている。例えば、ベッド装置は、背ボトム、腰ボトム、膝ボトム、足ボトムに別れており、各ボトムの傾動により患者等の身体を適切に支えることができる。この場合、可動部に対してアクチュエータ等の駆動装置を接続し、それぞれの可動部を動作させることが一般的である。 Conventionally, a body support device such as a bed device or a chair has a plurality of movable parts and is configured to more appropriately support the body of a patient or a caregiver by moving each of them. For example, the bed apparatus is divided into a back bottom, a waist bottom, a knee bottom, and a foot bottom, and a body such as a patient can be appropriately supported by tilting each bottom. In this case, it is common to connect a driving device such as an actuator to the movable part and operate each movable part.
　また、ベッド装置の高さを切り替えるハイロー機構（ＨＬ機構）を更に有している場合もある。この場合は、ベッド装置の高さを変更するための、駆動装置を更に設けることにより、ベッド装置の高さを適切な高さにすることが可能となる。 Also, there may be a high / low mechanism (HL mechanism) for switching the height of the bed apparatus. In this case, by further providing a drive device for changing the height of the bed apparatus, the bed apparatus can be set to an appropriate height.
　また、部品点数を減らすために、例えば背ボトムの回転駆動に連動して膝ボトムを回転駆動可能にする発明が開示されている（例えば、特許文献１参照）。 Further, in order to reduce the number of parts, for example, an invention is disclosed in which the knee bottom can be rotationally driven in conjunction with the rotational driving of the back bottom (see, for example, Patent Document 1).
特開２００９－２４０５８３号公報JP 2009-240583 A
　しかし、上述したように、従来の製品では可動部毎により駆動装置が必要となってしまい、コスト面が高くなってしまうといった課題が生じていた。さらに、駆動装置が多くなるほど、駆動装置の数だけメンテナンスが必要となってしまうという問題点も生じていた。 However, as described above, the conventional product requires a driving device for each movable part, which causes a problem that the cost is increased. Furthermore, there is a problem in that maintenance increases as the number of driving devices increases.
　更に、駆動装置を複数設けることにより、当該駆動装置を駆動させるための接続ケーブルの引き回しなどが必要となるため、ベッド装置や、椅子といった身体支持装置の内部にケーブルを引き回す空間が別途必要なるという問題点も生じていた。 Furthermore, by providing a plurality of driving devices, it is necessary to route connection cables for driving the driving devices, so that it is necessary to separately provide a space for routing the cables inside the body support device such as a bed device or a chair. There were also problems.
　また、上述の特許文献のような構成では、背ボトムと足ボトムとが同時に作動してしまうため、例えば背ボトムだけ作動させたい場合にはその都度切替える必要があった。とくに、切替えによっては、背ボトムだけ作動させるつもりが足ボトムも連動してしまったり、その逆の状態が生じたりする場合があり、利用者はどちらかの使い方を選択することがおおかった。更に、ハイロー機構については、異なる駆動装置が必要であった。 Further, in the configuration as described in the above-mentioned patent document, since the back bottom and the foot bottom operate simultaneously, for example, when it is desired to operate only the back bottom, it is necessary to switch each time. In particular, depending on the switching, there is a case where the intention is to operate only the back bottom, but the bottom of the foot is also interlocked, or the reverse situation occurs, and the user has to select one of the usages. Furthermore, for the high / low mechanism, a different driving device is required.
　上述した課題に鑑み、本発明は、一つの駆動装置を用いることで、複数の可動部を切り替えて動作させることにより、適切に身体を支持することが可能な身体支持装置等を提供することである。 In view of the above-described problems, the present invention provides a body support device that can appropriately support a body by switching and operating a plurality of movable parts by using one drive device. is there.

　本発明によれば、一つの駆動部だけで、複数の可動部を切り替えて作動させることが可能となる。例えば、ベッド装置であれば、背上げ動作、膝下げ動作、高さ調整といった複数の動作を、一つの駆動装置だけで適宜切り替えて動作をさせることが可能となる。 According to the present invention, it is possible to switch and operate a plurality of movable parts with only one drive part. For example, in the case of a bed apparatus, a plurality of operations such as a back raising operation, a knee lowering operation, and a height adjustment can be appropriately switched and operated by only one drive device.

　以下、本発明の実施形態について、添付図面を参照して説明する。なお、以下の実施形態は、本発明を説明するために必要な状態を記載したものであり、実施形態により本発明の内容を限定しているものではない。 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In addition, the following embodiment describes the state required in order to demonstrate this invention, and the content of this invention is not limited by embodiment.
　本明細書では、本発明を適用した身体支持装置の実施形態の一つとしてベッド装置に適用した場合の実施形態を説明する。 In the present specification, an embodiment when applied to a bed apparatus will be described as one embodiment of a body support apparatus to which the present invention is applied.
　図１は、ベッド装置１の外観を示した図である。また、図２はベッド装置１の機能を説明するための図である。ベッド装置１は、ボトムにマットレス（不図示）を載せた状態で使用者の荷重を支える（身体を支持する）ものである。ボトムは、使用者が頭と背を支える背ボトム１２と、腰を支える腰ボトム１４と、腰から膝までを支える膝ボトム１６と、膝から先の足を支える足ボトム１８の各板状部で構成されている。 FIG. 1 is a view showing the appearance of the bed apparatus 1. FIG. 2 is a diagram for explaining the function of the bed apparatus 1. The bed apparatus 1 supports a user's load (supports the body) with a mattress (not shown) placed on the bottom. The bottom is a plate-like portion of a back bottom 12 that supports the head and back of the user, a waist bottom 14 that supports the waist, a knee bottom 16 that supports from the waist to the knee, and a foot bottom 18 that supports the foot beyond the knee. It consists of
　ここで、背ボトムは駆動装置からの駆動力により、背ボトムを支える背ボトム機構２２が作動し、背上げ、背下げ動作が行われる。背上げ動作としては最大約７５度程度、背下げ動作としては略０度の状態まで背ボトムが回動する。 Here, the back bottom mechanism 22 that supports the back bottom is operated by the driving force from the drive device, and the back raising and lowering operations are performed. The back bottom rotates to a state of about 75 degrees at the maximum for the back raising operation and approximately 0 degrees for the back lowering operation.
　ここで、各機構は、例えばリンク機構等により実現されている。すなわち、駆動部４２からの駆動力がリンク機構を介すことにより、背ボトム１２に伝わることとなる。 Here, each mechanism is realized by a link mechanism, for example. That is, the driving force from the drive unit 42 is transmitted to the back bottom 12 through the link mechanism.
　膝ボトム１６、足ボトム１８についても、膝ボトム１６及び足ボトム１８を支える膝ボトム機構２４を介すことにより、駆動部４２からの駆動力が伝わっている。これにより、膝上げ（足下げ）動作が行われることとなる。 Also for the knee bottom 16 and the foot bottom 18, the driving force from the driving unit 42 is transmitted through the knee bottom mechanism 24 that supports the knee bottom 16 and the foot bottom 18. As a result, a knee-up (foot-down) operation is performed.
　更に、ベッド装置１の高さを調整出来るＨＬ機構２６が備えられている。ＨＬ機構２６も、例えばリンク機構により構成されている。駆動部４２からの駆動力により、ＨＬ機構２６が作動し、支持しているベッドフレームの高さを調整することができる。 Furthermore, an HL mechanism 26 that can adjust the height of the bed apparatus 1 is provided. The HL mechanism 26 is also constituted by a link mechanism, for example. The driving force from the driving unit 42 activates the HL mechanism 26, and the height of the supporting bed frame can be adjusted.
　ここで、ベッド装置には、駆動部４２を含む駆動制御部４０が設けられている。なお、駆動部４２は、例えばモータにより構成されている。駆動部４２は、伝達部を介して各機構部に接続されている。モータに接続されるシャフトが回転することにより、伝達部を介して各機構部に駆動力を伝えている。 Here, the bed apparatus is provided with a drive control unit 40 including a drive unit 42. In addition, the drive part 42 is comprised by the motor, for example. The drive part 42 is connected to each mechanism part via the transmission part. When the shaft connected to the motor rotates, the driving force is transmitted to each mechanism unit via the transmission unit.
　また、駆動制御部４０には、駆動部４２と、伝達部との間に切替部４４を更に備えている。 The drive control unit 40 further includes a switching unit 44 between the drive unit 42 and the transmission unit.
　図２に示すように、背ボトム機構２２に伝達部３２が、膝ボトム機構２４に伝達部３４が、ＨＬ機構２６に伝達部３６が接続されている。そして、各接続部が、切替部４４に接続されている。切替部は、接続された伝達部を選択的に切り替えることが可能である。伝達部を選択的に切り替えることにより、駆動力を伝える機構を選択することができる。例えば、伝達部３２が選択されると、背ボトム機構２２が作動する。これにより、背ボトム１２が動き、背上げ、背下げ動作を行うことができる。 2, the transmission unit 32 is connected to the back bottom mechanism 22, the transmission unit 34 is connected to the knee bottom mechanism 24, and the transmission unit 36 is connected to the HL mechanism 26. Each connection unit is connected to the switching unit 44. The switching unit can selectively switch the connected transmission units. By selectively switching the transmission unit, a mechanism for transmitting the driving force can be selected. For example, when the transmission unit 32 is selected, the back bottom mechanism 22 operates. Thereby, the back bottom 12 moves and can perform back raising and lowering operation.
　また、伝達部３４が選択されると、膝ボトム機構２４が作動する。これにより、膝ボトム１６、足ボトム１８が動き、膝上げ（足下げ）、膝下げ（足上げ）動作を行うことができる。 Also, when the transmission unit 34 is selected, the knee bottom mechanism 24 is activated. As a result, the knee bottom 16 and the foot bottom 18 move, and a knee-up (foot-down) and knee-down (foot-up) operations can be performed.
　また、伝達部３６が選択されると、ＨＬ機構２６が作動する。これにより、ハイローリンクが動き、ボトムの高さを変更することができる。 Also, when the transmission unit 36 is selected, the HL mechanism 26 operates. Thereby, the high-low link moves and the height of the bottom can be changed.
　このように、一つの駆動部を用いて、複数の可動部である機構を切り替えて作動させることが可能となる。したがって、可動部毎に駆動部を設けるよりコストとしても低廉で、かつ、メンテナンスが容易であるという効果が期待出来る。 Thus, it is possible to switch and operate a mechanism that is a plurality of movable parts using a single drive part. Therefore, it is possible to expect an effect that the cost is lower than that in which a driving unit is provided for each movable unit, and maintenance is easy.
　ここで、駆動制御部４０の実施例を図３、図４を用いて説明する。駆動部４２として、駆動モータ１０２が設けられている。駆動モータ１０２は、ウォームシャフト１０４が接続されている。駆動モータ１０２が駆動すると、ウォームシャフト１０４が回転する。ウォームシャフト１０４の途中には、複数のウォームギアが設けられている。 Here, an embodiment of the drive control unit 40 will be described with reference to FIGS. A drive motor 102 is provided as the drive unit 42. The drive motor 102 is connected to a worm shaft 104. When the drive motor 102 is driven, the worm shaft 104 rotates. A plurality of worm gears are provided in the middle of the worm shaft 104.
　図３では、３つの可動部（機構）が切り替え可能な図を示しているが、２つでも良いし、更に４つ以上でも良い。なお、説明の都合上、一つの構成を例に取って以下説明する。 FIG. 3 shows a diagram in which three movable parts (mechanisms) can be switched, but two or four or more may be used. For convenience of explanation, the following description will be given by taking one configuration as an example.
　ウォームシャフト１０４に設けられているウォームギア２０４に噛合するようにウォームホイール２０２が設けられている。このウォームホイール２０２は、駆動シャフト２１０の軸線上に回転自在となるように設けられており、また、クラッチ２０６（クラッチオス）が一体的に構成されている。 A worm wheel 202 is provided so as to mesh with a worm gear 204 provided on the worm shaft 104. The worm wheel 202 is provided so as to be rotatable on the axis of the drive shaft 210, and a clutch 206 (clutch male) is integrally formed.
　すなわち、駆動モータ１０２が駆動すると、ウォームシャフト１０４が回転する。ウォームシャフト１０４が回転すると、途中に設けられたウォームギア２０４が併せて回転し、噛合するウォームホイール２０２も回転する。ウォームホイール２０２が回転することにより、一体的に構成されているクラッチ２０６も回転する。 That is, when the drive motor 102 is driven, the worm shaft 104 rotates. When the worm shaft 104 is rotated, the worm gear 204 provided in the middle is also rotated, and the meshing worm wheel 202 is also rotated. As the worm wheel 202 rotates, the integrally formed clutch 206 also rotates.
　クラッチは、クラッチ２０６と、クラッチ２０８（クラッチメス）とが嵌合されるように形成されている。クラッチ２０６と、クラッチ２０８（クラッチメス）が接続されていない状態（離間している状態）のときは、駆動シャフト２１０に駆動力が伝わらない。したがって、駆動シャフト２１０に接続されるドライブシャフト４０２にも駆動力が伝わらないため、接続される機構は作動しない。 The clutch is formed so that the clutch 206 and the clutch 208 (clutch female) are engaged. When the clutch 206 and the clutch 208 (clutch female) are not connected (separated), the driving force is not transmitted to the drive shaft 210. Accordingly, since the driving force is not transmitted to the drive shaft 402 connected to the drive shaft 210, the connected mechanism does not operate.
　次に、ロック部３００により、クラッチ２０６と、クラッチ２０８とが接続された場合について説明する。クラッチ２０８は、駆動シャフト２１０に軸支されている。また、ロック部３００及びその近傍について、図５を用いて説明する。 Next, a case where the clutch 206 and the clutch 208 are connected by the lock unit 300 will be described. The clutch 208 is pivotally supported on the drive shaft 210. The lock unit 300 and the vicinity thereof will be described with reference to FIG.
　ロック部３００は、ロック部材３０２と、ロックシャフト３０４を備えて構成されている。ロック部材が押し込まれていないとき（解除状態）のときは、ロックシャフト３０４と、ロック部材３０２の傾斜面とが当接している。また、駆動シャフト２１０の一端に設けられた押し当て部材２００２が、ロック部材３０２に当接している。押し当て部材２００２は、ばね２００６を介して軸受２００８と接続している。軸受２００８は、駆動シャフト２１０の軸上に位置している。 The lock unit 300 includes a lock member 302 and a lock shaft 304. When the lock member is not pushed in (released state), the lock shaft 304 and the inclined surface of the lock member 302 are in contact with each other. In addition, a pressing member 2002 provided at one end of the drive shaft 210 is in contact with the lock member 302. The pressing member 2002 is connected to the bearing 2008 via a spring 2006. The bearing 2008 is located on the drive shaft 210.
　ロックシャフト３０４は、ばね（不図示）で支えられており、下方向に回動可能に設けられている。ここで、ロック部材３０２が図５（ｂ）に示すＳ方向に押されると、ロックシャフト３０４が一度さがり、ロック部材３０２を超えることで、ロック部３００はロック状態となる。 The lock shaft 304 is supported by a spring (not shown), and is provided to be rotatable downward. Here, when the lock member 302 is pushed in the S direction shown in FIG. 5B, the lock shaft 304 is once pulled and exceeds the lock member 302, so that the lock unit 300 is in a locked state.
　このとき、ロック部材３０２に当接されている押し当て部材２００２もＳ方向に押されることとなり、駆動シャフト２１０全体がＳ方向に移動する。これにより、駆動シャフト２１０に設けられているクラッチ２０８も移動し、クラッチ２０６に嵌合することとなる。 At this time, the pressing member 2002 in contact with the lock member 302 is also pressed in the S direction, and the entire drive shaft 210 moves in the S direction. As a result, the clutch 208 provided on the drive shaft 210 also moves and is engaged with the clutch 206.
　クラッチ２０６とクラッチ２０８とが嵌合することにより、クラッチ２０６の回転によりクラッチ２０８も回転することとなる。クラッチ２０８が回転すると、併せて駆動シャフト２１０も回転する。 When the clutch 206 and the clutch 208 are engaged, the clutch 208 is also rotated by the rotation of the clutch 206. When the clutch 208 rotates, the drive shaft 210 also rotates.
　駆動シャフト２１０は、中継パイプ２１２を介してドライブシャフト４０２が連結されている。ドライブシャフト４０２は、駆動シャフト２１０の回転により、ロッド４０４が伸縮する。ロッド４０４の先には、ベッド装置における可動部が接続されている。例えば背ボトム機構２２が接続されている場合は、背上げ、背下げの動作が行われることとなる。（図３、図４参照） The drive shaft 210 is connected to the drive shaft 402 via the relay pipe 212. In the drive shaft 402, the rod 404 is expanded and contracted by the rotation of the drive shaft 210. A movable part in the bed apparatus is connected to the tip of the rod 404. For example, when the back bottom mechanism 22 is connected, the operation of raising and lowering the back is performed. (See Figs. 3 and 4)
　なお、ドライブシャフト４０２とリンク機構等の可動部との間には、例えばトルクリミッタが接続されている。これにより、駆動モータ１０２からの駆動力は所定の力以上はかからないことになっている。すなわち、例えば背上げ角度が最大となった場合はそれ以上背ボトム機構２２は作動せず、背上げ角度が０度となった場合にはそれ以下は背ボトム機構２２は作動しない。 For example, a torque limiter is connected between the drive shaft 402 and a movable part such as a link mechanism. As a result, the driving force from the driving motor 102 does not exceed a predetermined force. That is, for example, when the back raising angle becomes maximum, the back bottom mechanism 22 does not operate any more, and when the back raising angle becomes 0 degrees, the back bottom mechanism 22 does not operate below that.
　また、他の可動部を選択する場合は、他のロック部の操作を行う。すなわち、他のロック部材が押されるときに、同じようにロックシャフトが下方向に回動する。そうすると、現在ロック状態だったロック部材３０２は、図５（ｂ）の状態から図５（ａ）の状態に戻ることとなる。また、押し当て部材２００２も、ばね２００６の力により、図５（ｂ）の位置から、図５（ａ）の位置に戻ることとなる。 Also, when selecting another movable part, operate the other lock part. That is, when another lock member is pushed, the lock shaft is similarly rotated downward. Then, the lock member 302 that is currently locked returns from the state shown in FIG. 5B to the state shown in FIG. Further, the pressing member 2002 also returns from the position of FIG. 5B to the position of FIG. 5A by the force of the spring 2006.
　図６は、駆動制御部４０の操作方法についての実施例である。例えば、図６（ａ）は、切り替える方式として駆動制御部４０ａにおける切り替えを手動で行う。また、駆動部４２については、接続された操作部５０ａを用いて操作する。操作部５０ａを操作することにより、駆動モータを動作させることが可能となる。 FIG. 6 shows an example of an operation method of the drive control unit 40. For example, in FIG. 6A, switching in the drive control unit 40a is manually performed as a switching method. The drive unit 42 is operated using the connected operation unit 50a. The drive motor can be operated by operating the operation unit 50a.
　なお、操作部としては、専用の操作装置（リモコン装置）であっても良いし、スマートフォンや他の携帯端末装置にアプリケーションを実行して実現する仕組みとしてもよい。 Note that the operation unit may be a dedicated operation device (remote control device), or may be realized by executing an application on a smartphone or another portable terminal device.
　図６（ｂ）は、駆動制御部４０ａに、そのまま操作部５０ｂを設けた場合の実施例である。駆動制御部４０ａに直接操作部５０ｂを設けることにより、より簡易に駆動制御部４０ａを提供することが出来る。 FIG. 6B shows an embodiment in which the operation control unit 50b is provided as it is in the drive control unit 40a. By directly providing the operation unit 50b in the drive control unit 40a, the drive control unit 40a can be provided more easily.
　図６（ｃ）は、駆動制御部４０ａに操作する手段を設けず、完全に操作部５０ｃのみで操作する場合である。例えば、切替部４４として、電磁クラッチで、駆動シャフトを切り替える方式を採用する。これにより、従来の製品と同様に、操作部のみで各機能部を切り替えて操作可能にしつつ、駆動部（駆動モータ）は１つで構成するといったことが実現可能である。 FIG. 6 (c) shows a case in which no operation means is provided in the drive control unit 40a, and the operation is completely performed only by the operation unit 50c. For example, the switching unit 44 employs a method of switching the drive shaft with an electromagnetic clutch. As a result, as with conventional products, it is possible to implement a single drive unit (drive motor) while switching each functional unit to be operable only with the operation unit.
　また、図７～図９は、切替部４４の他の動作について説明するための図である。例えば、図７は、スライド式のスイッチを設けており、スイッチをスライドさせることにより、カムが押される。これにより、クラッチが接続（クラッチオスとクラッチメスとが嵌合）されることとなる。なお、スライド式については手動でスライドしても良いし、電動でスライドさせる事としても良い。 7 to 9 are diagrams for explaining another operation of the switching unit 44. FIG. For example, in FIG. 7, a slide-type switch is provided, and the cam is pushed by sliding the switch. Thereby, a clutch will be connected (a clutch male and a clutch female will be fitted). In addition, about a slide type, you may slide manually and it is good also as making it slide electrically.
　図８は、クラッチを駆動シャフトとドライブシャフトとの間に設けた場合の実施例である。更に図９は、ロックバネ等を用いているが、単にロック部材を押すのではなく、つまみをロック部材の一端に設ける。つまみを回すことにより、ネジのように押し込まれ、クラッチが接続（クラッチオスとクラッチメスとが嵌合）する。 FIG. 8 shows an embodiment in which a clutch is provided between the drive shaft and the drive shaft. Further, FIG. 9 uses a lock spring or the like, but instead of simply pushing the lock member, a knob is provided at one end of the lock member. By turning the knob, it is pushed in like a screw and the clutch is connected (the clutch male and clutch female are fitted).
　また、異なる実施形態として、ボトム部を複数同時に作動させる構成としても良い。例えば、背ボトム１２と、膝ボトム１６（足ボトム１８）とが、リンク機構で接続されている場合を考える。 Further, as a different embodiment, a plurality of bottom portions may be operated simultaneously. For example, consider a case where the back bottom 12 and the knee bottom 16 (foot bottom 18) are connected by a link mechanism.
　この場合、ボトムの作動と、ＨＬ機構の作動とを切り替えることが可能である。ボトムの作動が選択された場合は、背上げと、膝上げ（足下げ）とが連動して行われることとなる。また、ＨＬ機構が選択された場合には、ベッドの高さが変わることとなる。 In this case, it is possible to switch between the bottom operation and the HL mechanism operation. When the bottom operation is selected, back-up and knee-up (foot-down) are performed in conjunction with each other. When the HL mechanism is selected, the bed height changes.
　このように、本実施形態によれば、一つの駆動モータで、駆動モータの駆動力を複数の可動部に伝えることができる。また、一つの駆動モータで、駆動モータの駆動力を同時に複数の可動部に伝えることもできる。したがって、従来に比べて低廉に装置を製造することが可能となる。 As described above, according to the present embodiment, the driving force of the driving motor can be transmitted to the plurality of movable parts with a single driving motor. Moreover, it is also possible to transmit the driving force of the driving motor to a plurality of movable parts at the same time with one driving motor. Therefore, it is possible to manufacture the device at a lower cost than in the past.
　また、駆動制御部４０を別構成としても良い。別構成とすることで、例えば駆動制御部４０だけを別途販売したり、後付けをすることにより、従来の手動操作のベッドの複数の動作を、切り替えつつ電動で行えたりできるという効果が期待できる。 Further, the drive control unit 40 may be configured separately. By adopting a separate configuration, for example, only the drive control unit 40 can be sold separately or retrofitted, so that an effect that a plurality of operations of a conventional manually operated bed can be performed electrically while switching can be expected.
　以上、この発明の実施形態について図面を参照して詳述してきたが、具体的な構成はこの実施形態に限られるものではなく、この発明の要旨を逸脱しない範囲の設計等も特許請求の範囲に含まれる。 The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and the design and the like within the scope of the present invention are also within the scope of the claims. include.
　上述した実施形態では、身体支持装置の一例としてベッド装置について説明した。本発明は複数の可動部があれば適用可能であり、例えば椅子型の身体支持装置、治療台、ストレッチャー、に適用可能である。また、用途としても病院・施設で患者・被介助者が利用するベッド装置だけでなく、手術用、透析・化学療法用、歯科治療用といった用途から、家庭用のベッド装置に適用可能なことは勿論である。 In the embodiment described above, the bed apparatus has been described as an example of the body support apparatus. The present invention is applicable if there are a plurality of movable parts, and is applicable to, for example, a chair-type body support device, a treatment table, and a stretcher. In addition to the bed equipment used by patients and caregivers in hospitals and facilities, it can be applied to home bed equipment for use in operations, dialysis / chemotherapy, dental treatment, etc. Of course.
　また、上述した実施形態では、各ボトムを作動させるための機構としてリンク機構を用いて説明したが、各ボトムを作動可能であればリンク機構でなくても良い。例えば、ドライブシャフト４０２（ロッド４０４）とボトムとを接続し、ロッド４０４の伸縮に応じて直接ボトムが作動してもよい。 In the above-described embodiment, the link mechanism is used as a mechanism for operating each bottom. However, the link mechanism may not be used as long as each bottom can be operated. For example, the drive shaft 402 (rod 404) and the bottom may be connected, and the bottom may operate directly according to the expansion and contraction of the rod 404.
