ここで、本発明の好適な車椅子又はベッド用固定装置の実施例を図面に沿って説明する。
[実施例１]
図１、図２は、本発明の車椅子又はベッド用の実施例１であるが、ベッドでベッドサイドテーブルとして使用できるが、主に車椅子に適したベッド用テーブルである。
図１で、車椅子又はベッド用のテーブル部１の上面は平坦で水平に保たれ、食事等に使用されるようになっており、テーブル部１は一本の支柱部２によって片側を支持され、この支柱部２は、通常、車椅子或いはベッドでの使用に適する位置するテーブル部１の高さを調整するため、伸縮機構によって伸縮自在になっており、高さ調節レバー３(図２(実施例２においては図６)）によって、支柱部２の高さを調整している。 Here, a preferred embodiment of the wheelchair or bed fixing device of the present invention will be described with reference to the drawings.
[Example 1]
1 and 2 show a wheelchair or bed according to a first embodiment of the present invention, which can be used as a bedside table in a bed, but is a bed table mainly suitable for a wheelchair.
In FIG. 1, the upper surface of the wheelchair or bed table 1 is kept flat and horizontal, and is used for meals, etc. The table 1 is supported on one side by a single column 2, In order to adjust the height of the table portion 1 which is usually suitable for use in a wheelchair or a bed, the support column portion 2 can be expanded and contracted by an expansion / contraction mechanism, and a height adjustment lever 3 (FIG. 2 (Example) In FIG. 2, the height of the column 2 is adjusted by FIG. 6)).

この支柱部２は、基礎部を構成する脚部４に固定され、脚部４は、大凡、Ｈ字状で平行な二本のキャスター付き支柱側脚部４１,挿入側脚部４２と、これを連結する連結枠体４３とから構成され、テーブルＡが転倒しないような形状をしている。前記Ｈ字状で平行な二本の支柱側脚部４１,挿入側脚部４２は、通常、支柱側脚部４１が車椅子Ｂ或いは ベッドＣの外側に配置され、主に支柱部２を支持し、挿入側脚部４２は車椅子Ｂ或いは ベッドＣの下に挿入してテーブルＡが倒れないような位置にするように構成されている。   The support column 2 is fixed to a leg 4 constituting a base, and the support 4 is generally H-shaped and parallel to a support-side leg 41 with casters, an insertion-side leg 42, Are connected to each other, and the table A is shaped so as not to fall down. The two H-shaped and parallel strut-side leg portions 41 and the insertion-side leg portion 42 are normally arranged such that the strut-side leg portion 41 is disposed outside the wheelchair B or the bed C and mainly supports the strut portion 2. The insertion-side leg portion 42 is configured to be inserted under the wheelchair B or the bed C so that the table A does not fall down.

実施例１ではテーブル部１の上面は、車椅子での食事に適するように、手前側１１は凹状の湾曲部１１１を有しており、手前側１１とは反対側１２の底部１２１は、支柱側脚部４１が連なっており、底部１２１にキャスター５を操作する操作レバー５３１（図２）が配置されている。
このテーブルＡ、特に脚部４の底面は、図２に示すように、ほぼＨ字状で、通常、車椅子ＢやベッドＣ(点線)（図５）の外側に位置する支柱側脚部４１の底面の両端部に位置する２箇所に、一対の比較的車輪直径が大きく、旋回ロック機構と車輪回転のロック機構とを有する大型の双輪キャスター５１が取付けられ、支柱部２から離れ、通常、車椅子ＢやベッドＣの下の空間に挿入する挿入側脚部４２の底面の両端部に位置する２箇所にも一対の比較的車輪の直径が小さく、床からの高さが前記双輪キャスター(キャスター機構)５１に比較して低い、扁平のキャスター(キャスター機構)５２(前掲、特許文献３を参照、実施例１の図１ではｈ＝2.8cm)が取付けられており、挿入や退出の移動の際には、これらのキャスター５のロック状態が操作部５３の操作レバー５３１の操作によって一斉に全部解除され、容易に移動することができる。 In the first embodiment, the front side 11 has a concave curved portion 111 so that the upper surface of the table unit 1 is suitable for a wheelchair meal, and the bottom 121 on the side 12 opposite to the front side 11 is the column side. The leg portion 41 is continuous, and an operation lever 531 (FIG. 2) for operating the caster 5 is disposed on the bottom portion 121.
As shown in FIG. 2, the bottom surface of the table A, in particular, the leg 4 is substantially H-shaped, and is usually a column-side leg 41 located outside the wheelchair B or bed C (dotted line) (FIG. 5). A pair of large two-wheel casters 51 having a relatively large wheel diameter and having a turning lock mechanism and a wheel rotation lock mechanism are attached to two positions located at both ends of the bottom surface, and are separated from the support column 2 and are usually wheelchairs. The diameter of the pair of wheels is relatively small at two positions located at both ends of the bottom surface of the insertion-side leg portion 42 to be inserted into the space below B or the bed C, and the height from the floor is the above-described twin-wheel caster (caster mechanism). ) A flat caster (caster mechanism) 52 (see the above-mentioned patent document 3, h = 2.8 cm in FIG. 1 of Example 1), which is lower than 51, is attached. The caster 5 is locked when the operation unit 5 is in a locked state. All the operation levers 531 are released all at once and can be moved easily.

脚部４は、支柱側脚部４１と連結枠体４３に取り付け、車椅子ＢやベッドＣの下に挿入する挿入側脚部４２が平面Ｈ字状に配置され、挿入側脚部４２の一対の先端部４２１には、中心角が１８０°以上の扇形の案内枠体４２２が設けられるが、この扇形の中心角は１８０°以上がよく、好ましくは、ほぼ２５０°から２９０°であり、本実施例１では２７０°の中心角である。
また、図３,４に示すように、案内枠体４２２の両先端部４２１間の距離は、車椅子Ｂの両側の枠体Ｂ１の内側よりも若干小さくしている。 The leg part 4 is attached to the column side leg part 41 and the connecting frame body 43, and the insertion side leg part 42 to be inserted under the wheelchair B or the bed C is arranged in a plane H shape. The tip portion 421 is provided with a fan-shaped guide frame 422 having a central angle of 180 ° or more. The central angle of the sector is preferably 180 ° or more, and preferably approximately 250 ° to 290 °. In Example 1, the central angle is 270 °.
As shown in FIGS. 3 and 4, the distance between the two end portions 421 of the guide frame 422 is slightly smaller than the inside of the frame B1 on both sides of the wheelchair B.

この案内枠体４２２の作用を図４、５を用いて説明する。
図４は、従来の車椅子用テーブルＡ１の上面図である。この場合に、車椅子Ｂの前面部Ｂ１の設けられている前輪キャスターＢ２の一方が、テーブルＡの挿入側脚部４２の両先端部４２１に車椅子Ｂ側の前輪キャスターＢ２が車椅子Ｂの前方枠体Ｂ３の内側に旋回したままである場合には、図示するように、挿入側脚部４２の両先端部４２１は前輪キャスターＢ２によってそれ以上挿入できない状態になり、これを是正するには、使用者が手で前輪キャスターＢ２を通路から除くように旋回させなければ、テーブルＡをそれ以上進行させることはできない。また、逆に進行後に前輪キャスターＢ２が通路側に旋回して飛び出た場合も同様の作業が必要となる。 The operation of the guide frame body 422 will be described with reference to FIGS.
FIG. 4 is a top view of a conventional wheelchair table A1. In this case, one of the front wheel casters B2 provided on the front surface portion B1 of the wheelchair B is connected to both end portions 421 of the insertion side leg portions 42 of the table A, and the front wheel caster B2 on the wheelchair B side is the front frame of the wheelchair B. In the case where the vehicle is still turning inside B3, as shown in the drawing, both end portions 421 of the insertion-side leg portion 42 cannot be inserted any more by the front wheel caster B2, and the user can correct the situation by correcting it. However, if the front wheel caster B2 is not turned by hand so as to remove it from the passage, the table A cannot be further advanced. On the other hand, when the front wheel caster B2 turns to the path side and jumps out after traveling, the same operation is required.

これに対して、実施例１の場合は、図４(ａ)〜（ｃ）に示すように、自然と車椅子Ｂの前輪キャスターＢ１が通路から旋回して退避させることができる。
これを順次説明すると、図４(ａ)では、テーブルＡの挿入側脚部４２の両先端部４２１に車椅子側の前輪キャスターＢ２が前方枠体Ｂ３の内側に旋回したままである場合に、挿入側脚部４２の両先端部４２１に設けた案内枠体４２２に前輪キャスターＢ２が接触する。
次に、図４(ｂ)では、外周扇形(円形)の案内枠体４２２に前輪キャスターＢ２が接触するが、テーブル部１とともに案内枠体４２２が更に進行すると、前輪キャスターＢ２は車椅子Ｂの両側の前方枠体Ｂ３の外側に押し出される。
こうして、次の図４(ｃ)では、車椅子Ｂの前輪キャスターＢ２は両側の前方枠体Ｂ３の外側に押し出されているので、挿入側脚部４２及び案内枠体４２２が更にスムースに所定の位置まで進入できる。
逆に、テーブルＡを車椅子Ｂから引き出す際に、前輪キャスターＢ２が後退する通路に突出していても、図２に示すように、中心角が２７０°の扇形の案内枠体４２２があるので、挿入側脚部４２の左右の枠よりも飛び出た扇形であるので、この部分でスムースに前輪キャスターＢ２を車椅子Ｂの両側の前方枠体Ｂ３の外側に押し出すことができる。 On the other hand, in the case of the first embodiment, as shown in FIGS. 4A to 4C, the front wheel caster B1 of the wheelchair B can naturally turn and retreat from the passage.
4A, when the front wheel caster B2 on the wheelchair side remains pivoted inside the front frame B3 at both end portions 421 of the insertion side leg portion 42 of the table A, The front wheel casters B <b> 2 come into contact with the guide frame bodies 422 provided at both tip portions 421 of the side legs 42.
Next, in FIG. 4B, the front wheel caster B2 comes into contact with the outer circumferential fan-shaped (circular) guide frame body 422. When the guide frame body 422 further advances together with the table 1, the front wheel caster B2 moves to both sides of the wheelchair B. Is pushed out of the front frame body B3.
Thus, in the next FIG. 4C, the front wheel casters B2 of the wheelchair B are pushed out of the front frame bodies B3 on both sides, so that the insertion-side legs 42 and the guide frame bodies 422 are further smoothly moved into a predetermined position. Can enter.
On the contrary, when the table A is pulled out from the wheelchair B, there is a fan-shaped guide frame 422 having a central angle of 270 ° as shown in FIG. Since it has a fan shape that protrudes from the left and right frames of the side leg portion 42, the front wheel casters B2 can be smoothly pushed out of the front frame B3 on both sides of the wheelchair B at this portion.

実施例１の車椅子用又はベッド用テーブルは、以上のような構成なので、車椅子の下に挿入移動する際に、挿入側脚部４２の両先端部４２１には外周が扇形の案内枠体４２２が設けられており、車椅子の前輪キャスターＢ２が、テーブルＡの挿入側脚部４２の両先端部４２１に車椅子側の前輪キャスターＢ２が接触する場合に、案内枠体４２２が車椅子側の前輪キャスターＢ２を旋回させ移動するように案内するので、スムースにテーブルＡの挿入側脚部４２を車椅子Ｂの下に挿入し移動することができ、挿入側脚部４２を車椅子Ｂの下から引き出す場合にも、同様に、スムースに引き出すことができ、車椅子Ｂの使用者や介護者や看護師等にとって、車椅子側の前輪キャスターの位置を旋回させるという煩わしい作業をしなくて済む。
また、複数の（双輪)キャスターは昇降するテーブル部１の１箇所に設けられた操作部５３の操作レバー５３１により、一括してキャスターをロック状態、及びロック解除状態に操作することができるので、車椅子Ｂの使用者や介護者や看護師等にとって簡単な作業となる。
更に、挿入側脚部４２の一対のキャスター５２(５)は、支柱側脚部４１のキャスタ−機構より高さが低いキャスタ機構が用いられているので、簡単にテーブルＡの挿入側脚部４２を車椅子の下に挿入し移動することができる。また、挿入側脚部４２を車椅子Ｂの下から引き出す場合にもスムースに引き出せる。 Since the wheelchair or bed table according to the first embodiment is configured as described above, the guide frame body 422 having a fan-shaped outer periphery is formed at both distal end portions 421 of the insertion-side leg portion 42 when being moved under the wheelchair. When the front wheel caster B2 of the wheelchair is in contact with the front end casters B2 on the wheelchair side at both end portions 421 of the insertion side leg portion 42 of the table A, the guide frame body 422 moves the front wheel caster B2 on the wheelchair side. Since it is guided to turn and move, the insertion side leg 42 of the table A can be smoothly inserted and moved under the wheelchair B, and even when the insertion side leg 42 is pulled out from under the wheelchair B, Similarly, the wheelchair B can be pulled out smoothly, and the user, the caregiver, the nurse, and the like of the wheelchair B do not need to perform the troublesome work of turning the position of the front wheel caster on the wheelchair side.
In addition, since the plurality of (two-wheeled) casters can be collectively operated to the locked state and the unlocked state by the operation lever 531 of the operation unit 53 provided in one place of the table unit 1 that moves up and down, This is a simple task for the wheelchair B user, caregiver, nurse, and the like.
Further, since the pair of casters 52 (5) of the insertion side leg portion 42 is a caster mechanism whose height is lower than that of the support side leg portion 41, the insertion side leg portion 42 of the table A is easily used. Can be inserted and moved under the wheelchair. Further, when the insertion side leg 42 is pulled out from under the wheelchair B, it can be pulled out smoothly.

[実施例２]
図５、図６は、本発明の車椅子又はベッド用の実施例２であるが、主にベッドサイドテーブルに適したテーブルである。
実施例２が実施例１と異なる点は、ベッドＣでの使用に適するように、テーブル部１の上面形状が矩形でサイズも大きく、それに伴い連結枠体４３も長く、挿入側脚部４２の両先端部４２１の距離も長くして安定性を向上させ、また、操作部５３及び操作レバー５３１も左右に設けている点であり、他の構成は同じであるので説明は省略する。
実施例２の作用は、ベッドＣの脚部ポールＣ１や脚部ポールＣ１のキャスターＣ２に挿入側脚部４２が接触しても、案内枠体４２２が扇型をしているので、案内枠体４２２によってキャスターＣ２を旋回移動させたり、挿入側脚部４２が脚部ポールＣ１に引っ掛かることなく移動することができる。 [Example 2]
5 and 6 show a wheelchair or bed embodiment 2 of the present invention, which is a table mainly suitable for a bedside table.
The second embodiment is different from the first embodiment in that the upper surface shape of the table portion 1 is rectangular and large in size so that it is suitable for use in the bed C, and the connecting frame body 43 is long accordingly. The distance between both tip portions 421 is also increased to improve stability, and the operation portion 53 and the operation lever 531 are also provided on the left and right sides.
The operation of the second embodiment is that the guide frame body 422 has a fan shape even when the insertion side leg portion 42 contacts the leg pole C1 of the bed C or the caster C2 of the leg pole C1. The caster C2 can be swiveled by 422, and the insertion side leg part 42 can be moved without being caught by the leg part pole C1.

したがって、実施例２の車椅子又はベッド用は、以上のような構成なので、ベッドＣの下の床に挿入移動する際に、挿入側脚部４２の両先端部４２１には外周が扇形の案内枠体４２２が設けられており、ベッドＣのキャスターＣ２が、テーブルＡの挿入側脚部４２の両先端部４２２にベッドＣ側のキャスターＣ２や脚部ポールＣ１に接触しても、前記案内枠体４２２がベッドＣ側のキャスターＣ２を旋回させ移動するように案内し、脚部ポールＣ１に引っ掛かることなくスムースに移動することができ、また、挿入側脚部４２２をベッドＣの下の床に挿入する場合も、逆に引き出す場合にも、案内枠体４２２の扇型は、中心角がほぼ２５０°から２９０°であるので、スムースに引き出すことができ、ベッドＣの使用者や介護者や看護師等にとって、ベッドＣ側のキャスターＣ２の位置を旋回させるという煩わしい作業をしなくて済む。
また、複数の双輪キャスター５２(５)は、昇降するテーブル部１の１箇所に設けられた操作部５３の操作レバー５３１により、一括して双輪キャスター５２(５)をロック状態、及びロック解除状態に操作されることができるので、ベッドＣの使用者や介護者や看護師等にとって簡単な作業となる。さらに、挿入側脚部４２の一対のキャスター機構５２は、支柱側脚部４１のキャスタ−機構５３より高さが低いキャスタ機構が用いられているので、簡単にテーブルＡの挿入側脚部４２をベッドＣの下の床に挿入し移動することができる。
なお、本発明の特徴を損なうものでなければ、上記の実施例に限定されるものでないことは勿論である。 Therefore, since the wheelchair or bed for the second embodiment is configured as described above, when inserting and moving to the floor under the bed C, the both outer end portions 421 of the insertion side leg portion 42 have fan-shaped guide frames. Even if the casters C2 of the bed C come into contact with the casters C2 and the leg poles C1 on the bed C side at both end portions 422 of the insertion side legs 42 of the table A, the guide frame body is provided. The 422 guides the caster C2 on the bed C side to pivot and move, and can move smoothly without being caught by the leg pole C1, and the insertion side leg 422 is inserted into the floor under the bed C. In both cases, the fan shape of the guide frame body 422 has a central angle of approximately 250 ° to 290 °, so that it can be pulled out smoothly. To teachers This eliminates the troublesome work of turning the position of the caster C2 on the bed C side.
The plurality of twin wheel casters 52 (5) are locked and unlocked by the operation lever 531 of the operation unit 53 provided at one position of the table unit 1 that is moved up and down. Therefore, it is easy for the user of the bed C, the caregiver, the nurse, and the like. Further, since the pair of caster mechanisms 52 of the insertion side leg portion 42 is a caster mechanism having a height lower than that of the caster mechanism 53 of the support side leg portion 41, the insertion side leg portion 42 of the table A can be easily attached. It can be inserted into the floor under the bed C and moved.
Needless to say, the present invention is not limited to the above-described embodiments as long as the features of the present invention are not impaired.
