【従来の技術】
近年、ベッド等（病院用ベッド、在宅用ベッド、移送用ベッド、ＩＣＵベッド等）に設けられる側柵には、ボトム側面に直接固定したボトム直付け型のものが提案されている。かかるボトム直付け型側柵３、３を、ボトム２の起伏機構（ギャッチ機構）を備えたベッド１の頭側およぴ足側に装着するようにすれば、ギャッチ動作させた際も、ボトム２の動きに側柵３、３が追従するので、常に、側柵３、３は、使用者を側面から支える位置にあるという、安全上、好ましい機能がもたらされる（図７参照）。
【０００３】
【発明が解決しようとする課題】
しかしながら、ボトム２の動きに側柵３、３が追従する際、人体や物の挟み込みを防止するため、側柵３、３間に所定の隙間Ｓを設けるようにしているので、この隙間Ｓから使用者が転落するおそれがあり、前記隙間Ｓをカバーする手段が求められていた。
本発明は、以上のような背景から提案されたものであって、床部起伏機構を有するベッド等の頭側、足側ボトム側面側に配設される側柵において、ベッド使用時には側柵の柵部間にある空間をカバーする一方、不必要時には側柵に格納しておけるようにした、ベッド等における側柵装置を提供することを目的とする。

また本発明では、請求項２において、前記補助柵にローラ部材を転動自在に突設し、前記補助柵を前記他方の側柵に向かって展開した際に、前記補助柵を前記ローラ部材を介して、他方の側柵の柵部に当接するようにしたベッド等における側柵装置を提案する。
また本発明では、請求項３において、床部起伏機構を有するベッド等の頭側、足側のボトム側面にそれぞれ側柵を配置し、これら頭側または足側のいずれかの側柵に、他方の側柵に向かって、柵部長手方向に突没可能に補助柵を設け、この補助柵を前記他方の側柵に向かって突出させて、前記他方の側柵の柵部に対し、変位可能に係止させてなるベッド等における側柵装置を提案する。
また本発明では、請求項４において、前記補助柵にフック部材を設ける一方、前記他方の側柵の柵部に係止軸を設け、前記補助柵を他方の側柵に向かって突出させて、前記補助柵のフック部材を他方の側柵の柵部における係止軸に変位可能に係止させてなるベッド等における側柵装置を提案する。
【０００５】
請求項１によれば、ベッド使用時、ベッド等の頭側、足側ボトム側面に配置した側柵間に補助柵を掛け渡しておき、ボトムのギャッチ動作時、頭側、足側ボトム側面の側柵と共に、補助柵も追従し、頭側、足側ボトム側の側柵間の隙間をカバーすることができる。ボトム上の使用者に接近して介護行為、治療行為を行うときや、ベッドへの乗り降りを行うときは、ベッド等の頭側、足側の側柵間を空けるべく、前記補助柵を、頭側または足側の側柵に格納させるようにする。
【０００６】
請求項２によれば、補助柵のローラ部材は、他方の側柵の柵部に当接した状態で転動移動し、補助柵は、ギャッチ動作に追従して変位する。
【０００７】
請求項３によれば、使用時に補助柵を、格納した頭側または足側の側柵から柵部長手方向に引き出して、他方の側柵の柵部に変位可能に係止させる。
【０００８】
請求項４によれば、ベッド使用時に、頭側または足側の側柵から、補助柵を他方の側柵に向かって突出させ、前記他方の側柵の柵部における係止軸に、補助柵側のフック部材を係止させるようにする。
【０００９】
【発明の実施の態様】
次に、本発明にかかるベッド等における側柵装置について、一つの実施の形態を示し、添付の図面に基づいて以下説明する。
図１に示すベッド１０は、ギャッチ機能を有するもので、分割構造のボトム１１のうちの頭側、すなわちヘッドボード１２側の背に対応する背ボトム１１ａと、足側、すなわちフットボード１３側の足に対応する足ボトム１１ｂ側面に側柵１４，１５をそれぞれ装着している。
これら側柵１４，１５は格納型側柵である。前記背ボトム１１ａ側面の側柵１４は、背ボトム１１ａの下方から背ボトム１１ａ上方に突出可能に取り付けた支柱部１４ａと、この支柱部１４ａ上端側に回動可能に取り付けた柵部１４ｂとを有している。また足ボトム１１ｂ側の側柵１５も同様に、足ボトム１１ｂの下方から足ボトム１１ｂ上方に突出可能に取り付けた支柱部１５ａと、この支柱部１５ａ上端側に回動可能に取り付けた柵部１５ｂとを有している。また、前記側柵１４，１５には、それぞれ支柱部１４ａ，１５ａ、柵部１４ｂ，１５ｂを背ボトム１１ａ、足ボトム１１ｂ上方に突出状態で保持するようにした拘束手段（図示省略）を有している。
【００１０】
前記側柵１４，１５のうち、背ボトム１１ａ側面の側柵１４において、柵部１４ｂの背ボトム１１ａ側に面する側に、ボトム端面に沿う方向に展開突出するように補助柵１６を軸止めしている。
この補助柵１６は前記柵部１４ｂとほぼ同形状とし、柵部１４ｂのベッド中央寄りの端部側に回動軸１７により軸止めされている（図２参照）。
また、前記補助柵１６の図中、ヘッドボード１２寄りの端部側には、補助柵１６を展開した際に、足ボトム１１ｂ側の側柵１５の柵部１５ｂに当接するようにした、ローラ部材１８を転動自在に突設している。
【００１１】
以上のような側柵１４，１５を装着したベッド１０において、ベッド使用時、例えば使用者の就寝時には、背ボトム１１ａ側面における側柵１４の柵部１４ｂから、柵部１４ｂのベッド中央寄りの端部側の回動軸１７を中心として、ボトム１１端面に沿う方向に補助柵１６を展開突出させるようにする。
すると、この補助柵１６の、ヘッドボード１２寄りのローラ部材１８が、足ボトム１１ｂ側の側柵１５の柵部１５ｂに当接した状態で支持される（図１参照）。これによって、背ボトム１１ａ側および足ボトム１１ｂ側の側柵１４，１５間の隙間が、前記補助柵１６によってカバーされ、転落などのおそれはない。
一方、介護者等がボトム１１上の使用者に接近して介護行為、治療行為を行うときや、ベッドへの乗り降りを行うときは、前記背ボトム１１ａ側および足ボトム１１ｂ側の側柵１４，１５間を解放するべく、前記補助柵１６を、背ボトム１１ａ側面における側柵１４の柵部１４ｂに、保持させるようにする。
【００１２】
そして、ベッド使用時、背ボトム１１ａ側および足ボトム１１ｂ側の側柵１４，１５間の隙間を、補助柵１６によってカバーした状態で、ギャッチ動作を行うと、背ボトム１１ａおよび足ボトム１１ｂの傾斜と共に、前記側柵１４，１５は追従傾斜する（図３参照）。
このとき、補助柵１６は、柵部１４ｂのベッド中央寄りの端部側の回動軸１７を中心として変位する一方、補助柵１６の、ヘッドボード１２寄りのローラ部材１８は、足ボトム１１ｂ側の側柵１５の柵部１５ｂに当接した状態で転動移動する。
従って、前記側柵１４，１５が背ボトム１１ａおよび足ボトム１１ｂの傾斜と共に追従傾斜しても、補助柵１６は前記側柵１４，１５の動きを妨げることなく、側柵１４，１５間の隙間をカバーした状態を維持することができる。
このように、ベッド使用時には、ボトム１１の平担時であっても、ギャッチ時であっても、側柵１４，１５間の隙間をカバーすることができ、使用者の転落を確実に防止することができる。
【００１３】
本発明にかかるベッド等における側柵装置は、以下のような構造によっても実施することができる。
すなわち、図４に示すギャッチベッド１０は、前述のベッド１０と同構造のもので、背ボトム１１ａ側および足ボトム１１ｂ側に装着される側柵２０、２１は、実質的には前記側柵１４，１５と同様、支柱部２０ａ，２１ａ、柵部２０ｂ，２１ｂで構成される格納型側柵である。
かかる側柵２０、２１のうち、背ボトム１１ａ側における側柵２０の柵部２０ｂに、柵部２０ｂ長手方向に突没可能に補助柵２２を保持する構成としている。
この場合、前記補助柵２２は、柵部２０ｂの、ベッド中央寄りの端部に近接した箇所に突設した支軸２３を、補助柵２２に形成した柵部長手方向に沿う、長穴２４に嵌入することで支持している。そして前記補助柵２２は、この長穴２４をガイドとして柵部長手方向にスライド可能としている。
また、前記補助柵２２には、ベッド中央寄りの端部に、補助柵２２を足ボトム１１ｂ側の側柵２１に向かって突出させた際、足ボトム１１ｂ側における側柵２１の柵部２１ｂに係止させるようにした、フック部材２５を設けている（図５参照）。すなわち、足ボトム１１ｂ側における側柵２１の柵部２１ｂには、前記フック部材２５と係止する係止軸２６を突設している。
なお、前記補助柵２２を突出させて、足ボトム１１ｂ側における側柵２１の柵部２１ｂに係止させた際、ボトム平担時には、柵部２０ｂにおける支軸２３は、補助柵２２における長穴２４の中途に位置するように、前記長穴２４の寸法を設定している。
【００１４】
以上のような側柵２０、２１を装着したベッド１０では、ベッド使用時に、背ボトム１１ａ側面における側柵２０の柵部２０ｂから、柵部２０ｂにおける支軸２３を補助柵２２側の長穴２４をガイドとして移動するように、補助柵２２を足ボトム１１ｂ側の側柵２１に向かって突出させ、前記側柵２１の柵部２１ｂにおける係止軸２６に、補助柵２２側のフック部材２５を係止させるようにする（図４参照）。
これによって、背ボトム１１ａ側および足ボトム１１ｂ側の側柵２０，２１間の隙間が、前記補助柵２２によってカバーされ、転落などのおそれはない。
【００１５】
そしてかかる状態で、ギャッチ動作を行うと、背ボトム１１ａおよび足ボトム１１ｂの傾斜と共に、前記側柵２０，２１は追従傾斜するわけであるが、補助柵２２は、側柵２０の柵部２０ｂと、柵部２０ｂにおける支軸２３を、補助柵２２側の長穴２４において移動可能に嵌入しており、一方、足ボトム１１ｂ側の側柵２１の柵部２１ｂにおける係止軸２６に、補助柵２２側のフック部材２５を係止させているので、側柵２０，２１の動きに連動して傾斜する。
前記側柵２０，２１が傾斜していくと、柵部２０ｂ，２１ｂ間の間隔が広がるが、背ボトム１１ａ側における側柵２０の柵部２０ｂの支軸２３が、補助柵２２側の長穴２４をずれながら長穴２４の図中、左端側まで移動することができるので、側柵２０，２１の動きを妨げることはない（図６参照）。
【００１６】
以上、本発明にかかるベッド等における側柵装置について、ギャッチベッドの例を示して説明したが、勿論、格納型側柵に限らない。またベッド頭側、足側に設けた側柵間の隙間をカバーする格納可能な補助柵を設けたものであれば、ギャッチ機能を有していないベッドに対しても適用可能である。この場合、ギャッチ機能を有していないベッドに対しては、ボトム以外の箇所に固定した側柵によっても、本発明にかかるベッド側面カバー構造を実現できる。
【００１７】
【発明の効果】
以上の通り、本発明によれば、ベッド使用時、ベッドの頭側と、足側に配置した側柵間を補助柵によってカバーすることができ、転落などのおそれはない。
また、ギャッチベッドに補助柵を有する側柵を設けた場合、ギャッチ動作によっても、側柵の動きを妨げることなく、追従して側柵間をカバーすることができる。
一方、不必要時には補助柵を側柵に格納しておけるので、保管場所などの心配もない。

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Next, an embodiment of a side fence device in a bed or the like according to the present invention will be described with reference to the accompanying drawings.
The bed 10 shown in FIG. 1 has a gatch function, and has a back bottom 11a corresponding to the head side of the bottom 11 of the divided structure, that is, the back on the headboard 12 side, and the foot side, that is, the footboard 13 side. Side fences 14 and 15 are respectively attached to the side surfaces of the foot bottom 11b corresponding to the feet.
These side fences 14, 15 are retractable side fences. The side fence 14 on the side surface of the back bottom 11a includes a pillar 14a attached to the back bottom 11a so as to protrude from below the back bottom 11a and a fence 14b rotatably attached to the upper end of the pillar 14a. Have. Similarly, the side fence 15 on the side of the foot bottom 11b is also provided with a column 15a that is mounted so as to protrude above the bottom 11b from below the bottom 11b, and a fence 15b that is rotatably mounted on the upper end side of the column 15a. And Further, the side fences 14 and 15 have restraining means (not shown) for holding the pillars 14a and 15a and the fences 14b and 15b in a protruding state above the back bottom 11a and the foot bottom 11b, respectively. ing.
[0010]
Of the side fences 14 and 15, the auxiliary fence 16 is fixed to the side fence 14 b on the side surface of the back bottom 11 a so as to expand and protrude in the direction along the bottom end face on the side facing the back bottom 11 a side of the fence 14 b. are doing.
The auxiliary fence 16 has substantially the same shape as the fence 14b, and is fixed to the end of the fence 14b near the center of the bed by a rotating shaft 17 (see FIG. 2).
Further, in the drawing of the auxiliary fence 16, on the end side near the headboard 12, when the auxiliary fence 16 is deployed, a roller which comes into contact with the fence portion 15 b of the side fence 15 on the foot bottom 11 b side is provided. The member 18 is provided so as to roll freely.
[0011]
In the bed 10 equipped with the side fences 14 and 15 as described above, when the bed is used, for example, when the user goes to bed, the end of the side fence 14b on the side of the back bottom 11a from the side of the side fence 14b toward the center of the bed. The auxiliary fence 16 is extended and protruded in a direction along the end surface of the bottom 11 around the rotation shaft 17 on the side of the unit.
Then, the roller member 18 of the auxiliary fence 16 near the headboard 12 is supported in a state of contact with the fence portion 15b of the side fence 15 on the foot bottom 11b side (see FIG. 1). As a result, the gap between the side fences 14 and 15 on the back bottom 11a side and the foot bottom 11b side is covered by the auxiliary fence 16, and there is no danger of falling.
On the other hand, when a caregiver or the like approaches a user on the bottom 11 to perform a nursing care or medical treatment, or when getting on or off a bed, the side fences 14 on the back bottom 11a side and the foot bottom 11b side. The auxiliary fence 16 is held by the fence 14b of the side fence 14 on the side surface of the back bottom 11a so as to open the space between the fences 15.
[0012]
When the bed is used and the gap operation between the side fences 14 and 15 on the back bottom 11a side and the foot bottom 11b side is covered by the auxiliary fence 16, the inclination of the back bottom 11a and the foot bottom 11b is performed. At the same time, the side fences 14 and 15 follow and incline (see FIG. 3).
At this time, the auxiliary fence 16 is displaced about a pivot shaft 17 on the end side of the fence 14b near the center of the bed, while the roller member 18 of the auxiliary fence 16 near the headboard 12 is moved toward the foot bottom 11b. Rolls while contacting the fence 15b of the side fence 15.
Therefore, even if the side fences 14 and 15 follow and incline with the inclination of the back bottom 11a and the foot bottom 11b, the auxiliary fence 16 does not hinder the movement of the side fences 14 and 15 and the gap between the side fences 14 and 15 is maintained. Can be maintained.
In this manner, when the bed is used, the gap between the side fences 14 and 15 can be covered even when the bottom 11 is laid flat or when the bed is gatched, and the fall of the user is reliably prevented. be able to.
[0013]
The side fence device in a bed or the like according to the present invention can also be implemented by the following structure.
That is, the gatch bed 10 shown in FIG. 4 has the same structure as the bed 10 described above, and the side fences 20, 21 mounted on the back bottom 11a side and the foot bottom 11b side are substantially the side fences 14, 21. Similar to 15, this is a retractable side fence composed of struts 20 a and 21 a and fences 20 b and 21 b.
Of the side fences 20, 21, the fence 20b of the side fence 20 on the side of the back bottom 11a holds the auxiliary fence 22 so as to be able to protrude and retract in the longitudinal direction of the fence 20b.
In this case, the auxiliary fence 22 is configured such that a support shaft 23 protruding from a portion of the fence portion 20b close to the end near the center of the bed is inserted into an elongated hole 24 along the longitudinal direction of the fence formed on the auxiliary fence 22. It is supported by fitting. The auxiliary fence 22 is slidable in the longitudinal direction of the fence using the long hole 24 as a guide.
When the auxiliary fence 22 is protruded toward the side fence 21 on the foot bottom 11b side at the end near the center of the bed, the auxiliary fence 22 is formed on the side fence 21b of the side fence 21 on the foot bottom 11b side. A hook member 25 is provided to be locked (see FIG. 5). That is, a locking shaft 26 for locking with the hook member 25 is protruded from the fence 21b of the side fence 21 on the foot bottom 11b side.
When the auxiliary fence 22 is protruded and locked to the fence 21b of the side fence 21 on the side of the foot bottom 11b, the support shaft 23 of the fence 20b is elongated when the bottom is flat. The size of the elongated hole 24 is set so as to be located in the middle of the elongated hole 24.
[0014]
In the bed 10 equipped with the side fences 20 and 21 as described above, at the time of use of the bed, the support shaft 23 in the fence 20b is connected to the elongated hole 24 on the auxiliary fence 22 side from the fence 20b of the side fence 20 on the side surface of the back bottom 11a. The auxiliary fence 22 is protruded toward the side fence 21 on the side of the foot bottom 11b so as to move as a guide, and the hook member 25 on the auxiliary fence 22 side is attached to the locking shaft 26 of the fence 21b of the side fence 21. It is locked (see FIG. 4).
As a result, the gap between the side fences 20 and 21 on the side of the back bottom 11a and the side of the foot bottom 11b is covered by the auxiliary fence 22, and there is no risk of falling.
[0015]
When the gatch operation is performed in such a state, the side fences 20 and 21 follow and tilt together with the inclination of the back bottom 11a and the foot bottom 11b. The support shaft 23 of the fence 20b is movably fitted in the elongated hole 24 on the side of the auxiliary fence 22. On the other hand, the auxiliary fence is fitted on the locking shaft 26 of the fence 21b of the side fence 21 on the side of the foot bottom 11b. Since the hook member 25 on the 22 side is locked, it is inclined in conjunction with the movement of the side fences 20 and 21.
As the side fences 20 and 21 incline, the distance between the fences 20b and 21b increases, but the support shaft 23 of the fence 20b of the side fence 20 on the back bottom 11a side is elongated in the auxiliary fence 22 side. Since it is possible to move to the left end side in the figure of the elongated hole 24 while displacing it, it does not hinder the movement of the side fences 20, 21 (see FIG. 6).
[0016]
As described above, the side fence device in the bed and the like according to the present invention has been described with reference to the example of the gatch bed, but is not limited to the retractable side fence. In addition, as long as a retractable auxiliary fence is provided to cover a gap between side fences provided on the bed head side and the foot side, the present invention can be applied to a bed having no gatch function. In this case, for a bed that does not have a gatch function, the bed side cover structure according to the present invention can be realized even with side fences fixed at locations other than the bottom.
[0017]
【The invention's effect】
As described above, according to the present invention, when the bed is used, the space between the head side of the bed and the side fence arranged on the foot side can be covered by the auxiliary fence, and there is no risk of falling down.
When the side fence having the auxiliary fence is provided on the gatch bed, the gap between the side fences can be covered by the gatch operation without obstructing the movement of the side fence.
On the other hand, when unnecessary, the auxiliary fence can be stored in the side fence, so there is no need to worry about a storage place.
