Description

本発明は、ベッド装置に関し、特に使用者の背部を支える背板がフレームに対して起伏動作をなすベッド装置に関する。   The present invention relates to a bed apparatus, and more particularly, to a bed apparatus in which a back plate that supports a user's back part performs an up-and-down motion with respect to a frame.

上記したタイプのベッド装置においては、背板の起立動作時、使用者が腹部に圧迫感を受けるという問題点が夙に知られており、この問題点を解決する手段が、例えば特許文献１に明示されている。すなわち、特許文献１が開示するベッド装置においては、かような問題を解消するために、背板の、使用者の腰部に相当する部位を凸状に変形させ、この状態を保持したまま、背板の起立動作を行うようになっている。上記した部位を凸状に変形させることで、使用者の腰部が反った状態となり、使用者の姿勢が前かがみにならず、使用者の腹部が圧迫感を受けないようになっている。
特開２００２−１７２１４４号公報 In the above-mentioned type of bed apparatus, it is well known that the user receives a feeling of pressure on the abdomen during the standing motion of the back plate, and means for solving this problem is disclosed in Patent Document 1, for example. It is specified. That is, in the bed apparatus disclosed in Patent Document 1, in order to solve such a problem, a portion of the back plate corresponding to the user's waist is deformed into a convex shape, and this state is maintained while the back is maintained. The plate is erected. By deforming the above-mentioned part into a convex shape, the user's waist is warped, the user's posture is not bent forward, and the user's abdomen is not subjected to a feeling of pressure.
JP 2002-172144 A

しかしながら、上記したベッド装置においては、背板の、使用者の腰部に相当する部位（腰部背板）を凸状に変形させ、この状態を保持したまま、背板の起立動作を行うようになっているので、使用者が寝た状態（背板が水平のとき）で腰部背板が凸になると腹部が伸ばされ、使用者は苦しくなる。また、背板の起立動作完了時、使用者の腰部が、いわば持ち上がった状態になるので、使用者の身体が前方（足側）にずれるという問題がある。   However, in the bed apparatus described above, the portion of the back plate corresponding to the user's waist (lumbar back plate) is deformed into a convex shape, and the back plate is raised while maintaining this state. Therefore, if the lumbar back plate becomes convex while the user is lying down (when the back plate is horizontal), the abdomen is stretched, and the user becomes painful. In addition, when the standing motion of the back plate is completed, the user's waist is in a lifted state, so there is a problem that the user's body shifts forward (to the foot).

それ故に、本発明は、かような不具合が惹起されることがない、ベッド装置を提供することを、その課題とする。   Therefore, an object of the present invention is to provide a bed apparatus that does not cause such a problem.

上記の課題を解決するために請求項１で講じた技術的手段は、「使用者の背部を支える背板部を、腰部を支える腰部支持部と前記腰部以外の背部たる背中上部を支える背中上部支持部とから構成し、前記背板部の起立動作中には前記背中上部に対して略面一をなしていた前記腰部支持部がせり出し、前記背板に起立動作終了直前には前記腰部支持部が再度、前記背中上部支持部に対して略面一となるようにした、ベッド装置」を構成したことである。   In order to solve the above-mentioned problem, the technical means taken in claim 1 is: “the back plate portion supporting the user's back portion, the back support portion supporting the waist portion and the upper back portion supporting the back portion other than the waist portion. The lumbar support portion that is substantially flush with the upper back during the upright operation of the back plate portion protrudes and the lumbar support is supported immediately before the end of the upright operation. The bed apparatus is configured such that the portion is again substantially flush with the upper back support portion.

請求項１に記載の発明によれば、背板部の起立動作の終了直前までは、使用者の腰部が反った状態となり、使用者の姿勢が前かがみにならず、使用者の腹部が圧迫感を受けず、また、背板部の起立動作の終了直前には、使用者の腰部の持ち上がり状態が解消されるので、使用者の身体が前方（足側）にずれるということはない。   According to the first aspect of the present invention, the user's waist is warped until the end of the standing motion of the back plate, and the user's posture does not lean forward, and the user's abdomen feels tight. In addition, since the lifting state of the user's waist is canceled immediately before the end of the standing motion of the back plate, the user's body does not shift forward (foot side).

以下、本発明を実施するための最良の形態を、図面を基に説明する。   The best mode for carrying out the present invention will be described below with reference to the drawings.

図１に示されるように、ベッド装置１０は、フレーム１２を備える。フレーム１２上の右側（図示されない使用者の頭部側）には、背板部２０が、後述するように、起伏可能に配設される。背板部２０の左側（使用者の足側）においては、使用者の臀部を支持する尻部支持板１４が、フレーム１２に固定される。フレーム１２上においては、尻部支持板１４の左側（使用者の足側）には、図示されない脚部支持部が配設される。この脚部支持部は、フレーム１２に固定される平板形式であっても良いし、「ヘ」状に屈曲して膝曲げ可能な形式であっても良い。   As shown in FIG. 1, the bed apparatus 10 includes a frame 12. On the right side (the user's head side not shown) on the frame 12, as will be described later, a back plate portion 20 is disposed so as to be able to undulate. On the left side of the back plate portion 20 (on the user's foot side), a buttocks support plate 14 that supports the user's buttocks is fixed to the frame 12. On the frame 12, a leg support portion (not shown) is disposed on the left side (the user's foot side) of the buttocks support plate 14. The leg support portion may be a flat plate type fixed to the frame 12, or may be a type that can be bent in a “f” shape and bendable to the knee.

背板部２０は、金属枠の形態をなすベース部材２２と、ベース部材２２の頭部側に固定される背中上部支持部２４と、ベース部材２２の足側端部にヒンジ装着された腰部支持部２６とから構成される。腰部支持部２６のヒンジ回動を可能ならしめるために、腰部支持部２６の右側（頭側）端部と背中上部支持部２４の左側（足側）端部との間には、空隙が形成される。   The back plate 20 includes a base member 22 in the form of a metal frame, a back upper support 24 fixed to the head side of the base member 22, and a waist support that is hinged to the foot side end of the base member 22. Part 26. A gap is formed between the right side (head side) end portion of the lumbar support portion 26 and the left side (foot side) end portion of the upper back support portion 24 in order to make the hinge support portion 26 pivotable. Is done.

背板部２０のベース部材２２は、リンク機構３０を介して駆動源たるアクチュエータ４０に連係ないしは作用的に関連付けられており、アクチエータ４０の一方向（他方向）駆動により、リンク機構３０がベース部材２２を起立（伏臥）するようになっている。すなわち、アクチュエータ４０はフレーム１２の下側にピン７０により回動可能に配設されており、アクチュエータ４０の本体４２からはロッド４４が出没自在に嵌装されている。ロッド４４の先端部は、リンク３２の下端部にピン４６で枢支されており、リンク３２の上端部はレバー３４の下端部にピン３６により一体的に連結されており、このピン３６は、フレーム１２の側面に回動自在に連結される。レバー３４の上端部には車輪３８が全方向転動可能に保持されており、この車輪３８がベース部材２２を支持している。   The base member 22 of the back plate 20 is linked to or operatively associated with an actuator 40 that is a drive source via a link mechanism 30, and the link mechanism 30 is moved to the base member by driving in one direction (the other direction) of the actuator 40. 22 is standing (prone). That is, the actuator 40 is rotatably disposed on the lower side of the frame 12 by the pin 70, and the rod 44 is fitted from the main body 42 of the actuator 40 so as to be able to appear and retract. The tip of the rod 44 is pivotally supported by a pin 46 at the lower end of the link 32, and the upper end of the link 32 is integrally connected to the lower end of the lever 34 by a pin 36. It is rotatably connected to the side surface of the frame 12. A wheel 38 is held at the upper end of the lever 34 so as to be able to roll in all directions, and the wheel 38 supports the base member 22.

腰部支持部２６の下面には、カム体２８が設けられている。カム体２８のカム面は、腰部支持部２６の下面と平行をなすフラット面２８ａと頭部側に傾斜する斜面部２８ｂとから構成されている。   A cam body 28 is provided on the lower surface of the waist support portion 26. The cam surface of the cam body 28 is composed of a flat surface 28 a that is parallel to the lower surface of the waist support portion 26 and an inclined surface portion 28 b that is inclined toward the head side.

背板部２０のベース部材２２の下面からは、下方向に延びるブラケット５０が連結されている。ブラケット５０の先端部は、バー５２の左側近傍に、ピン５４により枢着されており、この枢着により、バー５２はピン５４を中心として回動可能となっている。バー５２の右端部はピン５６によりは、フレーム１２の側面に枢着されており、この枢着により、バー５２はピン５６を中心として回動可能となっている。バー５２の左端部には、ピン５８によりローラ６０が回転可能に装着されている。   A bracket 50 extending downward is connected to the lower surface of the base member 22 of the back plate portion 20. The front end of the bracket 50 is pivotally attached to the vicinity of the left side of the bar 52 by a pin 54, and the bar 52 can be rotated around the pin 54 by this pivotal attachment. The right end of the bar 52 is pivotally attached to the side surface of the frame 12 by a pin 56, and the bar 52 can be rotated about the pin 56 by this pivotal attachment. A roller 60 is rotatably attached to the left end portion of the bar 52 by a pin 58.

図１に示すような状態、つまりアクチュエータ４０が静止している状態においては、アクチュエータ４０の本体４２及びロッド４４は、レバー３４と平行をなし、リンク３２及びブラケット５０は上下方向に延在して相互に平行をなし、ローラ６０はカム体２８のフラット面２８ａと離間・対峙している。
図２に示されるように、アクチュエータ４０が駆動されて、ロッド４４が本体４２内に引き込まれると、リンク３２がピン３６を中心に反時計方向に回動する。上記したように、リンク３２はレバー３４と連動する。レバー３４の下端部もピン３６を中心として反時計方向に回動する。しかして、この反時計方向に回動するレバー３４の上端部に転動自在に保持されている車輪３８は背板部２０のベース部材２２の下面を支持しているので、背板部２０のベース部材２２の頭側を起立させる。つまり、ベース部材２２は、その足側を支点として反時計方向に回動する。 In the state shown in FIG. 1, that is, the actuator 40 is stationary, the body 42 and the rod 44 of the actuator 40 are parallel to the lever 34, and the link 32 and the bracket 50 extend in the vertical direction. The rollers 60 are parallel to each other, and the rollers 60 are spaced apart from and opposed to the flat surface 28a of the cam body 28.
As shown in FIG. 2, when the actuator 40 is driven and the rod 44 is pulled into the main body 42, the link 32 rotates about the pin 36 in the counterclockwise direction. As described above, the link 32 is interlocked with the lever 34. The lower end of the lever 34 also rotates counterclockwise about the pin 36. Thus, the wheel 38 that is rotatably held at the upper end of the lever 34 that rotates in the counterclockwise direction supports the lower surface of the base member 22 of the back plate 20. The head side of the base member 22 is raised. That is, the base member 22 rotates counterclockwise with its foot side as a fulcrum.

上記したように、ベース部材２２と一体のブラケット５０は、バー５２の足側端部近傍に枢着されているので、ベース部材２２及びブラケット５０と一体となった反時計方向への回動により、バー５２はピン５６を中心として時計方向に回動する。バー５２の足側端部に回転可能に装着されたローラ６０は、図１に示す状態では、カム体２８のフラット面２８ａと離間対峙しているが、バー５２の時計方向回動により、ローラ６０がカム体２８のフラット面２８ａと当接する。時計方向回動するバー５２と一体のローラ６０がカム体２８のフラット面２８ａと当接することにより、腰部支持部２６が、反時計回動中のベース部材２２から起立する。この起立した腰部支持部２６が使用者の腰部を反った状態となして、使用者の姿勢が前かがみにならず、使用者の背中が圧迫感を受けない。   As described above, the bracket 50 integrated with the base member 22 is pivotally mounted in the vicinity of the foot side end portion of the bar 52, so that the bracket 50 integrated with the base member 22 and the bracket 50 is rotated counterclockwise. The bar 52 rotates clockwise around the pin 56. In the state shown in FIG. 1, the roller 60 rotatably attached to the foot side end of the bar 52 is opposed to the flat surface 28 a of the cam body 28. 60 contacts the flat surface 28 a of the cam body 28. When the roller 60 integrated with the bar 52 that rotates clockwise contacts the flat surface 28a of the cam body 28, the waist support portion 26 stands up from the base member 22 that rotates counterclockwise. The standing lumbar support portion 26 is in a state of warping the user's lumbar region, so that the posture of the user does not lean forward, and the user's back does not feel pressure.

しかして、アクチュエータ４０のロッド４４が本体４２に最大限に引き込まれる寸前、つまり背板部の起立動作の終了直前、図３に示されるように、バー５２と一体のローラ６０は、斜面２８ｂとの当接を経て、腰部支持部２６の下面と当接する。これにより、バー５２と一体のローラ６０による、ベース部材２２からの腰部支持部２６の起立は解消され、腰部支持部２６は、最初の状態のように、背中上部支持部２４と略面一となる。つまり、背板部の起立動作の終了直前には、使用者の腰部の持ち上がり状態が解消される、使用者の身体が前方（足側）にずれるということはない。   Accordingly, as shown in FIG. 3, immediately before the rod 44 of the actuator 40 is pulled into the main body 42 to the maximum extent, that is, immediately before the end of the standing operation of the back plate, as shown in FIG. After the contact, the contact with the lower surface of the waist support portion 26 is made. Thereby, the standing of the waist support part 26 from the base member 22 by the roller 60 integrated with the bar 52 is eliminated, and the waist support part 26 is substantially flush with the upper back support part 24 as in the initial state. Become. That is, immediately before the end of the standing motion of the back plate portion, the lifting state of the user's waist is eliminated, and the user's body does not shift forward (foot side).
