There is a bed that performs a back-raising operation, a leg-raising operation, and the like of a user who is using the bed.
このようなベッドの背ボトムとしては、従来、スチールやプラスチックからなる硬質のパネルを備え、背上げ動作時には上記パネルがその尻ボトム側の端部を支点として回動するものが一般に使用されている。このベッドは、回動する背ボトムによって使用者の背中に背上げ圧迫力を加えることにより、使用者の上体を起こすものである。この場合、背ボトムの回動と同時に背ボトムを斜め上に移動させたり、尻ボトムを下方に下げたりすることにより、背上げ動作時に使用者に加わる背上げ圧迫力を軽減する構造の介護支援ベッドもある（例えば、特許文献１参照）。 Conventionally, the back bottom of such a bed is generally provided with a hard panel made of steel or plastic, and the panel rotates with the end of the bottom bottom side as a fulcrum at the time of raising the back. . This bed raises the upper body of the user by applying a back-up compression force to the user's back by the rotating back bottom. In this case, care support with a structure that reduces the back-lifting pressure applied to the user during the back-lifting operation by moving the back bottom diagonally upward or lowering the bottom bottom simultaneously with the rotation of the back bottom There is also a bed (see, for example, Patent Document 1).
しかしながら、従来の背ボトムは、硬質のパネルによって使用者に背上げ圧迫力を加えるため、使用者に加える背上げ圧迫力を調節することができず、そのため使用者の体格に応じて使用者に適切な背上げ圧迫力を加えることができなかった。 However, since the conventional back bottom applies a back-up pressure force to the user by a rigid panel, the back-up pressure force applied to the user cannot be adjusted, and therefore the user can be adjusted according to the user's physique. Appropriate back-up pressure could not be applied.
本発明はこのような点に鑑みてなされたものであり、使用者に加える背上げ圧迫力を調節することができ、したがって使用者の体格に応じて適切な背上げ圧迫力を加えることにより、使用者の背中部に加わる圧迫力を緩和することができるベッド用背ボトムを提供することを目的とする。 The present invention has been made in view of the above points, and can adjust the back-raising compression force applied to the user.

また、引張応力調節手段１６は、背上げ部材１０の一端側にのみ設けてもよいが、本実施形態のように背上げ部材１０の両端に取り付けて形成することがより好ましい。 Further, the tensile stress adjusting means 16 may be provided only on one end side of the back raising member 10, but it is more preferable that the tensile stress adjusting means 16 is attached to both ends of the back raising member 10 as in the present embodiment.
その他の構成は、従来公知のベッド用背ボトムと同様とされているので、その詳しい説明については省略する。 Other configurations are the same as those of a conventionally known bed back bottom, and thus detailed description thereof is omitted.
つぎに、前述した構成からなる本実施形態の作用について説明する。 Next, the operation of the present embodiment having the above-described configuration will be described.
本実施形態のベッド用背ボトム１を背上げ機構を具備するベッドに用いる場合、調節用帯状体１５に取り付けられた引張応力調節手段１６を操作、具体的には、係合体１４を帯状体１０の適宜位置の被係合体１３に係合することにより、弾性体１２による帯状体１１の引張強度を使用者の体格に応じて調節する。 When the bed back bottom 1 of the present embodiment is used for a bed having a back raising mechanism, the tensile stress adjusting means 16 attached to the adjustment band 15 is operated, specifically, the engagement body 14 is used as the band 10. The tensile strength of the band-like body 11 by the elastic body 12 is adjusted according to the user's physique by engaging the engaged body 13 at an appropriate position.
この時、引張応力調節手段１６が背上げ部材１０に取り付けられているので、引張応力調節手段１６、詳しくは、被係合体１３、係合体１４および調節用帯状体１５が背上げ部材１０から分離し脱落するのを容易に防止することができる。なお、各被係合体１３には、引張強度の強さを示す番号、記号、色などを表示することができる。 At this time, since the tensile stress adjusting means 16 is attached to the back raising member 10, the tensile stress adjusting means 16, specifically, the engaged body 13, the engaging body 14, and the adjusting strip 15 are separated from the back raising member 10. It can be easily prevented from falling off. Each engaged body 13 can be displayed with a number, a symbol, a color and the like indicating the strength of the tensile strength.
そして、使用者がベッドを使用する際には、使用者がベッドに寝た状態で、電動操作によりベッド用背ボトム１４を起立させ、背上げ動作を行う。この時、上述のように使用者の体格に応じて弾性体１２による帯状体１１の引張強度を調節することにより、電動によって背上げ動作をするときに、自力で背上げをする体位移動状態と同様に背中部が湾曲した帯状体１１に支えられ、使用者の背中部にかかる圧迫を緩和することができる。また、背ボトム１４の角度が５０度を超えると、背ボトム１４にかかる体荷重が減少し、弾性体１２の復元力が働き、背中の湾曲が伸びて座る体位となる。 When the user uses the bed, the bed back bottom 14 is erected by electric operation while the user is lying on the bed, and the back lifting operation is performed. At this time, by adjusting the tensile strength of the belt-like body 11 by the elastic body 12 according to the physique of the user as described above, when performing a back-up operation by electric power, Similarly, it is supported by the belt-like body 11 whose back portion is curved, and the pressure applied to the back portion of the user can be relieved. Moreover, when the angle of the back bottom 14 exceeds 50 degrees, the body load applied to the back bottom 14 is reduced, the restoring force of the elastic body 12 works, and the back curve is extended and the body sits.
このように、本実施形態のベッド用背ボトム１によれば、引張応力調節手段１６によって帯状体１１の引張強度を調節することができるので、使用者に加わる背上げ圧迫力を容易に調節することができ、したがって使用者の体格に応じて適切な背上げ圧迫力を加えることにより、使用者の背中部に加わる圧迫力を緩和することができる。 Thus, according to the bed back bottom 1 of the present embodiment, the tensile strength of the belt-like body 11 can be adjusted by the tensile stress adjusting means 16, so that the back-up pressure applied to the user is easily adjusted. Therefore, by applying an appropriate back-up compression force according to the user's physique, the compression force applied to the user's back can be reduced.
さらに、本実施形態のベッド用背ボトム１によれば、引張応力調節手段１６が背上げ部材１０に取り付けられているので、弾性体１２による帯状体１１の引張強度を調節する際に、調節用帯状体１５から手を離しても、調節用帯状体１５が背上げ部材１０から分離して脱落することがない。その結果、操作性、すなわち使い勝手の向上を容易かつ確実に図ることができる。 Furthermore, according to the bed back bottom 1 of the present embodiment, since the tensile stress adjusting means 16 is attached to the back raising member 10, when adjusting the tensile strength of the belt-like body 11 by the elastic body 12, it is used for adjustment. Even if the hand is released from the band 15, the adjustment band 15 does not separate from the back-up member 10 and fall off. As a result, it is possible to easily and reliably improve operability, that is, usability.
また、本実施形態のベッド用背ボトム１によれば、引張応力調節手段１６が弾性体１２に一端が取り付けられ、背上げ部材１０の帯状体１１の端部に重なるように配設された湾曲可能な調節用帯状体１５と、背上げ部材１０の帯状体１１の端部に、その長手方向に沿って配列された複数の被係合体１３と、調節用帯状体１５に取り付けられた係合体１４とを具備しており、複数の被係合体１３に対する係合体１４の係合位置を背上げ部材１０の帯状体１１の長手方向の中央側にすることで、弾性体１２を伸長させて背上げ部材１０の帯状体１１の引張強度を増強するように構成されているから、簡単な構成で、弾性体１２による帯状体１１の引張強度の調節、すなわち、使用者に加わる背上げ圧迫力をより容易に調節することができる。 Further, according to the bed back bottom 1 of the present embodiment, the tensile stress adjusting means 16 is curved so that one end is attached to the elastic body 12 and overlaps the end of the belt-like body 11 of the back raising member 10. A possible adjustment band 15, a plurality of engaged bodies 13 arranged along the longitudinal direction at the end of the band 11 of the back raising member 10, and an engagement body attached to the adjustment band 15 14, and the engagement position of the engagement body 14 with respect to the plurality of engaged bodies 13 is set to the center side in the longitudinal direction of the belt-like body 11 of the back raising member 10, thereby extending the elastic body 12 and Since it is comprised so that the tensile strength of the strip | belt-shaped body 11 of the raising member 10 may be reinforced, adjustment of the tensile strength of the strip | belt-shaped body 11 by the elastic body 12, ie, the back raising compression force added to a user, with simple structure.
