Description

本発明は、ベッドへの乗降を容易ならしめる介助装置に関する。   The present invention relates to an assistance device that facilitates getting on and off a bed.

ベッドへの乗降を容易ならしめる介助装置としては、例えば、特許文献1に明示されているものがある。この介助装置は、ベッドのサイドフレームにおける支柱に把持バーを所定の位置に回動させて固定する支持位置切換機構を介して取り付ける構成とされている。そして、支持位置切換機構は、支柱に固定された連結軸先端部に固定ギヤを取り付け、把持バーに一対のストッパを先端部が固定ギヤの歯に弾発的に当接係止するようにし、これらストッパ間に扇形状のカム部材を操作レバーにより回動可能に介在させる。   As an assistance device that makes it easy to get on and off the bed, for example, there is one that is explicitly disclosed in Patent Document 1. The assisting device is configured to be attached to a support in a side frame of the bed through a support position switching mechanism that rotates and fixes a gripping bar to a predetermined position. The support position switching mechanism attaches a fixed gear to the distal end portion of the connecting shaft fixed to the support column so that the pair of stoppers are elastically contacted and locked to the teeth of the fixed gear on the gripping bar, A fan-shaped cam member is interposed between these stoppers by an operation lever.

かように構成された介助装置たる把持バーを用いることにより、使用者は、ベッドから降りてベッドサイドにて起座し、ベッドサイドから立ち上がることが可能となる。
実開平5−56126号公報
By using the gripping bar as the assisting device configured as described above, the user can get off the bed, get up at the bedside, and stand up from the bedside.
Japanese Utility Model Publication No. 5-56126

上記したベッド装置においては、支柱が固定されるサイドフレームは高さが一定であるが、このサイドフレームが昇降装置により上昇されるものである場合、床面から高い位置で、把持バーが支柱にカンチレバーの態様で連結されることになる。従って、把持バーの長さが長いと、把持バーの先端側に作用する力が大きい場合、大きなモーメントにより、ベッド装置が横に傾く危惧がないとはいえない。   In the bed apparatus described above, the side frame to which the column is fixed has a constant height, but when the side frame is lifted by the lifting device, the gripping bar is placed on the column at a high position from the floor surface. They are connected in a cantilever manner. Therefore, if the length of the gripping bar is long, if the force acting on the tip end side of the gripping bar is large, it cannot be said that there is no risk that the bed apparatus will tilt sideways due to a large moment.

それ故に、本発明は、かような危惧がないベッド装置を提供することを、その課題とする。   Therefore, this invention makes it the subject to provide the bed apparatus which does not have such a concern.

上記の課題を解決するために講じた技術的手段は、「昇降可能なベッドサイドフレームに設けられる転落防止枠に対して回動し、前記転落防止枠に対して垂直方向の軸を中心に水平方向に回動可能となり、固定手段により回動固定が行える逆L型の管部材を備えた介助装置において、
前記管部材は下方が床面に着座する垂直部と、水平方向に延在する水平部とを有し該水平部よりも低い位置に水平方向に延在する上下の横バーと該横バー間に設けられ、両端が垂直方向に支持される縦棒に、使用者がベッドサイドに起座した状態から立ち上がる際、ベッドサイドと対向した状態となり使用者が前方で把持可能な把持部を備えたことを特徴とする介助装置」を構成したことである
The technical means taken in order to solve the above-mentioned problem is “rotating with respect to a fall prevention frame provided on the bedside frame that can be moved up and down, and horizontally with respect to the vertical axis with respect to the fall prevention frame. In the assisting device provided with the inverted L-shaped tube member that can be rotated in the direction and can be fixed by the fixing means ,
A vertical portion the tube member which is downwardly seated on the floor, and a horizontal portion extending in a horizontal direction, and upper and lower horizontal bars which extend horizontally at a position lower than the horizontal part, transverse A vertical bar provided between the bars and supported vertically at both ends, when the user stands up from the bedside, the gripping part that faces the bedside and can be gripped by the user forward This means that the “assisting device characterized by comprising” is configured .

本発明によれば、管部材は下方が床面に着座する垂直部と、水平方向に延在する水平部とを有し、水平部よりも低い位置に水平方向に延在する上下の横バーと、横バー間に設けられ、両端が垂直方向に支持される縦棒に、使用者がベッドサイドに起座した状態から立ち上がる際、ベッドサイドと対向した状態となり使用者が前方で把持可能な把持部を備えたことにより、把持部の使用を安定的に行うことができる。 According to the present invention, the pipe member has a vertical part whose lower part is seated on the floor surface and a horizontal part extending in the horizontal direction, and upper and lower horizontal bars extending in the horizontal direction at a position lower than the horizontal part. When the user stands up from the state where the user is seated on the bedside, the vertical bar provided between the horizontal bars and supported at both ends in the vertical direction is opposed to the bedside and can be gripped by the user in the front. Since the grip portion is provided, the grip portion can be used stably.

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及び図2に示されるように、ベッド装置10は、ヘッド部12及びフット部(図示略)を備える。ヘッド部12は、昇降装置121及びこの昇降装置121により昇降されるヘッドボード122とから構成され、昇降装置121の下部の支持部123は床面に着座する。フット部も、ヘッド部12と同じような構成とされる。   As shown in FIGS. 1 and 2, the bed apparatus 10 includes a head portion 12 and a foot portion (not shown). The head unit 12 includes an elevating device 121 and a head board 122 that is moved up and down by the elevating device 121, and a lower support portion 123 of the elevating device 121 is seated on the floor surface. The foot part has the same configuration as the head part 12.

ヘッドボード122とフットボード、一対のフレーム16・16(一方のみ図示)により連結される。フレーム16・16の上にはボトム部20が装着されており、ボトム部20上にはマットレス40が載置されている。しかして、ヘッドボード122及びフットボード142は、夫々、昇降装置121及び昇降装置(図示略)により同期して昇降可能となっているので、この同期昇降により、ヘッドボード122とフットボード142とを連結するサイドフレーム16・16上のボトム部20及びマットレス40が昇降可能とされる。   The head board 122 and the foot board are connected by a pair of frames 16 and 16 (only one is shown). A bottom portion 20 is mounted on the frames 16 and 16, and a mattress 40 is placed on the bottom portion 20. Since the headboard 122 and the footboard 142 can be moved up and down in synchronization by the lifting device 121 and the lifting device (not shown), respectively, the headboard 122 and the footboard 142 are moved by the synchronous lifting. The bottom part 20 and the mattress 40 on the side frames 16 and 16 to be connected can be moved up and down.

ベッド装置10には、介助装置50が付設されており、使用者Hは、ベッド装置10から降りてベッドサイドにて起座し、介助装置50の把持部56を握って、ベッドサイドの床面から立ち上がることを可能としている。   The bed apparatus 10 is provided with an assistance device 50, and the user H gets out of the bed apparatus 10 and sits up at the bedside, grasps the grip 56 of the assistance device 50, and moves to the bedside floor. It is possible to stand up from.

介助装置50を、特に図2を参照しつつ、詳細に説明する。ベッド装置10に付設される転落防止枠90は、本体部92、本体部92と一体のベース部94及びベース部94を半径方向に貫通突出する一対の突起部96・96とから構成される。突起部96の下枠から下方に突出する一対の突起部96・96が、ベッド装置10のサイドフレーム16から外方向に突出するように固定されたブラケット(図示略)に穿設された穴に挿入され、これにより、転落防止枠90がベッド装置10に堅牢且つ着脱自在に固定される。   The assistance device 50 will be described in detail with particular reference to FIG. The fall prevention frame 90 attached to the bed apparatus 10 includes a main body 92, a base 94 integrated with the main body 92, and a pair of protrusions 96 and 96 that protrude through the base 94 in the radial direction. A pair of projecting portions 96 and 96 projecting downward from the lower frame of the projecting portion 96 are formed in holes formed in a bracket (not shown) fixed so as to project outward from the side frame 16 of the bed apparatus 10. Thus, the fall prevention frame 90 is firmly and detachably fixed to the bed apparatus 10.

転落防止枠90のベース部94の右端部には、上下方向に延在するガイド部材60から半径方向に突出する分岐部60aが外装・固定される。ガイド部材60の上端部には、支持体62が回転可能に挿入・載置されている。支持体62には、軸方向に貫通する角穴が設けられている。この角穴内には、角棒52が、この角穴内に軸方向に相対移動可能に嵌着されており、この嵌着により、角棒52は、支持体62と一体となって、ガイド部材60に対して相対回動が可能となる。角棒52の回動位置は、固定手段59により固定される。すなわち、固定手段59の摘みを引くと角棒52が回動可能となり、摘みを放すと、角棒52の回動が不能となる。角棒52の下端部は、アジャスタ72を介して床面に着座する。   A branch portion 60 a that projects in the radial direction from the guide member 60 extending in the vertical direction is fixed to the right end of the base portion 94 of the fall prevention frame 90. A support body 62 is rotatably inserted and placed on the upper end portion of the guide member 60. The support body 62 is provided with a square hole penetrating in the axial direction. In this square hole, a square bar 52 is fitted into the square hole so as to be capable of relative movement in the axial direction. Relative rotation is possible. The rotation position of the square bar 52 is fixed by the fixing means 59. That is, when the knob of the fixing means 59 is pulled, the square bar 52 can be rotated, and when the knob is released, the square bar 52 cannot be rotated. The lower end portion of the square bar 52 is seated on the floor surface via the adjuster 72.

角棒52の上端部は、コーナー部が丸みを帯びた逆L型の管部材51の一端部と連結されている。管部材51の他方端部は、アジャスタ70を介して、床面に着座する。管部材51の他方端部近傍と角棒52の下端部近傍とは、横棒54により連結されており、この横バー54となす管部材51の水平部は、人が立ち上がったときに把持出来るようになっている。また、管部材51の水平部と平行をなすように、この平行部より少しく低い位置において、横バー53が角棒52と管部材51の垂直部とを連結している。この横バー53は、人が中腰になったときに把持出来るようになっている。 The upper end portion of the square bar 52 is connected to one end portion of an inverted L-shaped tube member 51 having a rounded corner portion. The other end of the pipe member 51 is seated on the floor surface via the adjuster 70. The vicinity of the other end of the tube member 51 and the vicinity of the lower end of the square bar 52 are connected by a horizontal bar 54, and the horizontal part of the tube member 51 that forms the horizontal bar 54 can be gripped when a person stands up. It is like that. Further, a horizontal bar 53 connects the square bar 52 and the vertical portion of the tube member 51 at a position slightly lower than the parallel portion so as to be parallel to the horizontal portion of the tube member 51. The horizontal bar 53 can be gripped when a person is in the middle.

横バー53には、管部材51の垂直部寄りにおいて、固定手段57が設けられており、また、横バー54には、管部材51の垂直部寄りにおいて、固定手段58が設けられている。固定手段57と固定手段58との間には、上下方向に延在する縦棒55が設けられており、この縦棒55は、U字型のパイプで形成された把持部56の両端部が溶着固定されている。この把持部56に、上記したように、使用者Hは、ベッド装置10から降りてベッドサイドにて起座し、介助装置50の把持部56を握って、ベッドサイドの床面から立ち上がることが出来るようになっている。 The horizontal bar 53 is provided with fixing means 57 near the vertical portion of the pipe member 51, and the horizontal bar 54 is provided with fixing means 58 near the vertical portion of the pipe member 51. A vertical bar 55 extending in the vertical direction is provided between the fixing means 57 and the fixing means 58, and the vertical bar 55 is formed at both ends of the grip portion 56 formed of a U-shaped pipe. It is fixed by welding. As described above, the user H can get off from the bed apparatus 10 and sit on the bedside, hold the gripping part 56 of the assistance device 50, and stand up from the bedside floor. It can be done.

上記したように、ベッド装置10のフレーム16は昇降するようになっているので、この昇降に伴い、転落防止枠90のベース部94及びガイド部材60も昇降する。しかして、ガイド部材60は角棒52との上下方向の相対変移が許容されるようになっているので、把持部56の位置は不変で、フレーム16の昇降にかかわらず、安定的に床面に支持される。   As described above, since the frame 16 of the bed apparatus 10 is moved up and down, the base portion 94 and the guide member 60 of the fall-preventing frame 90 are also moved up and down along with the movement. Thus, since the guide member 60 is allowed to move relative to the square bar 52 in the vertical direction, the position of the gripping portion 56 is not changed, and the floor surface can be stably stabilized regardless of whether the frame 16 is raised or lowered. Supported by

尚、固定手段57を緩めて把持部56を持ち上げれば、把持部56は縦棒55と一体となって回動し、縦棒55と管部材51の垂直部との間に画成される空間に折り畳み収容されるようになっている。   If the fixing means 57 is loosened and the gripping part 56 is lifted, the gripping part 56 rotates together with the vertical bar 55 and is defined between the vertical bar 55 and the vertical part of the tube member 51. It is designed to be folded and accommodated in the space.
