Description

【0001】
車が階段を昇降するには、平坦な地面と異なり、階段の形状、蹴上げ、踏面、等の寸法を測定しそれに対応する動きが求められるため、従来多種多様のセンサーを駆使し、複雑で高価な制御装置を多用してきた。本発明の階段昇降車はモード変換やクラッチ等の切り換え操作を駆使せず、上述のセンサーや制御装置を全く必要としないことを特徴とするものである。
【0002】
すなわち、平坦走行時には原動機付きで駆動側の歯車が車輪の被駆動側の歯車を回転させるが、車輪が階段の蹴込みにあたって車輪の回転が停止し、被駆動側の歯車の回転が停止すると、駆動側の歯車が被駆動側の歯車の廻りを公転する(或いは被駆動側の歯車の回転速度が遅くなった分だけ駆動側の歯車が被駆動側の歯車の廻りを公転する)。
【0003】
本発明の階段昇降車はこのピニオンの公転を階段昇降車の昇降動作に利用するもので、クラッチ等の切替装置を使わず平坦走行と昇降動作の2つのモード変換を交互に繰り返させるものである。
【0004】
車輪の回転と停止した車輪の廻りの公転とを繰り返す本発明の階段昇降車は、複数の車輪が絡み合うものと、1つの車輪内部で車輪外周内側を車軸に取り付いたピニオンが移動するものとがあり、前者には車輪を鎖状に連ねるものと車輪を放射状に配置するものとがある。後者には車輪の形状が円形から三角形などの多角形が考えられる。
【0005】
ここで車の昇段時と降段時とのそれぞれにおいて車輪の回転方向とピニオンあるいは車輪の公転方向がともに昇段方向あるいは降段方向に合致しておれば車は階段を昇降することになる。
【0006】
本発明の階段昇降車は車輪の回転の停止によりピニオンの公転を誘発させることが絶対条件で、そのためには車輪とノンスリップとの間でスリップしないことが不可避でタイヤには色々の工夫が施される。
【0007】
また昇段時にピニオンの公転が継続せず車輪後部がノンスリップから離れて持ち上げられ公転が終了し車輪が回転し始め平坦走行に復帰させるためには補助車輪などの介助が必要になる. この補助車輪の介助は同時に車軸の(ピニオンの中心の)軌跡を上にあるいは下に凹の円の一部をより直線に近くする効果がある。
【0008】
この車輪後部を押し上げる補助車輪の動きはピニオンの公転に連動して車輪の下に潜り込み踏面上を滑走するもので、より車輪後部を押し上げるためと昇段前に補助車輪が蹴込みにあたってピニオンの公転を阻止しないように渦巻き補助車輪などが考案される。
人や荷物を安全かつスムーズに上階にあげたり下階に下ろしたりするためには椅子や荷台の水平を維持し車が下の段に落ちないように車輪の降段方向の回転を阻止しなければならない。本発明は椅子や荷台を吊り下げる吊り材が車体が傾いたときも鉛直を保つことを利用して、車体が傾く動きを椅子や荷台を水平に保つ動きに替え、動力に頼らず自動的に椅子や荷台を水平に保つもので、車体が傾いたとき車輪の降段方向の回転阻止はラチェット爪を吊り下げることで解決される。
【図面の簡単な説明】
【0009】
まず平坦走行する本発明の階段を昇降する車輪が蹴込みに当たるとクラッチなどの切り替え操作なしに階段の昇段に移るかについて説明する。電動機等によって回転されるモーター歯車が車輪歯車を回転させる方式として歯車を噛み合わせて回転を伝えるものと、チェインを介在させて回転を伝えるものとがあり、被駆動側の回転を止めると駆動側の歯車は被駆動側の歯車のまわりを公転し、被駆動側の回転が止まることにより被駆動側の回転から駆動側の公転に切り替わる現象が認められる。
【0010】
[図1](a),(b),(c)はそれぞれ、車輪円周の内歯車を、車輪中心に位置する外歯車を、車輪中心に位置するチェイン歯車を車輪円周に位置するピニオンが電動機等により車輪に回転を与えて平坦走行するもので、車輪が蹴込みに当たり回転が止まると、回転が停止した内歯車(a)、外歯車(b)、あるいはチェイン歯車あるいはプーリー(c)のまわりをピニオンが公転する。 ( a )( b ) ( c )はともに、ピニオンが平坦走行の初期状態から昇段へ移行した状態をしめすものである。以下、図中→印は階段上昇時の歯車の回転方向、⇒印は歯車の公転方向を示す。
【0011】
[図2] (a),(b),(c)はそれぞれ、内側をチェイン(或いはvベルト或いは内歯車或いはラック)を貼り付けた円形、正方形、正三角形、菱形の車輪を示し、内部のチェイン歯車のピニオンは車体を支持する車軸歯車である。(a)では内部のチェイン歯車は円形車輪に回転を与えるが車輪の停止に伴いその外周内側をチェイン歯車が移動する。(b),(c)では内部のチェイン歯車はそれぞれの辺上を移動するが、その頂点の内側を通過する時その頂点を中心に車輪全体を回転させる。
【0012】
[ 図3 ] [ 図4 ] [ 図5 ]はモーター歯車の周りにそれと咬みあう複数個の歯車を放射状に配置し正三角形の盤に取り付けた階段昇降車で、(a)(b)はともに階段昇降車の昇段開始状態図をしめす。走行動作は車輪の回転であり、昇降動作は盤の公転である。
【0013】
車輪の回転と連結板の公転は互いに他方が停止すれば一方が開始し自動的に切り替わるモーターの回転を継続したままで車輪の回転と連結板の公転を交互に繰り返せば走行動作と上昇動作とが繰り返される。
昇降動作において太陽車軸を中心に車輪あるいは盤が公転することは見方を変えれば停止した接地輪を中心に太陽車軸が公転することでもある。
【0014】
[ 図3 ] ( a )ではモーター歯車の周りの複数個の歯車と同軸の車輪の前進が阻まれることで[ 図3 ]、(b)では遊星歯車の公転が阻まれることで、接地輪が停止する。
[ 図4 ] は図3( a )でモーター歯車の廻りに放射状に配置した歯車に取り付いた車輪を取り外したもので、車輪の前進が阻まれることで車軸歯車が車輪歯車との中間に介在する歯車の廻りを公転する。(a)は、昇段開始時の状態図(b)は、昇段直前の状態図(c)は、上段走行の状態図
【0015】
[図5]は、車軸歯車(54)部分に遊星歯車(53)と太陽歯車(51)を内蔵する内歯車(50)からなる遊星歯車機構を備える車輪で、各車輪(7)は車軸歯車(54)に噛合う車輪歯車(56)に取り付き、全部で車輪が6個の場合、3個の車輪が表面で車軸(2)から放射状に配置され盤(46)に取り付けられる。各車輪(7 a )は車軸歯車 ( 54)に噛合う車輪歯車(56 a )に取り付く
【0016】
残り3個の車輪(7b)は裏面で車軸(2)と遊星歯車(53)を取り付ける盤(47)に取り付けられる。各車輪(7b)は車軸歯車 ( 4)に噛合う車輪歯車(56b)に取り付く
【0017】
(a)は、構造図を表面から見た正面図(b)は、構造図の裏面図(a)(b)に於いて点線で書いた車輪(7)と車輪歯車(56)は反対側の面にあることを示す。
【0018】
裏面の盤(47)の公転の停止時、太陽歯車(51)の回転は遊星歯車(53)を介して内歯車(50)および車軸歯車(54)に伝達され、これに噛合う車輪歯車(56b)が回転する。
【0019】
(b)に示すように車輪(7)が蹴込みに当たって回転が停止すると、内歯車(50)および車軸歯車(54)の回転が停止し盤(47)の公転が起こる。
【0020】
盤(47)に取り付く裏面の各車輪歯車(56b)は車軸歯車(54)に沿って回転しながら公転する。
【0021】
(a)は、構造図(b)は、階段上昇開始時の状態図(c)は、部品配置図である。(a)の構造図と(b)の階段上昇開始時の状態図に示すように,外側に外歯車(54)が、内側に内歯車(50)の歯が取り付いた環状の歯車は、「車軸(2)を中心に回転可能な車軸歯車(54)と内歯車(50)を備え車軸を中心に回転可能な回転体(59)」である。また(c)の部品配置図に示すように車軸歯車(54)と内歯車(50)は一体の「車軸(2)を中心に回転可能な車軸歯車(54)と内歯車(50)を備え車軸を中心に回転可能な回転体(59)」である。
【0022】
[図6](a)(b)は接地側の下辺9aとその対面の上辺9bの2辺と2個の頂点からなる二辺車輪で、図2(b)(c)に示す多角形車輪を最も簡略化したものである。
【0023】
[図6](a)に示すように二辺車輪が接地状態にあってピニオンが下辺に噛合う時、ピニオン3aは下辺9a上を走行し車輪内部を移動する。また図6(b)に示すように二辺車輪が接地状態でなく空中に浮いた状態でピニオンが上辺に噛合う時、ピニオン3b二辺車輪を前方に送り出す。
【0024】
図6(c)(d)(e)(f)は車軸(2)を中心に回転する盤(13)の両端にピニオンを取り付けて、2個の二辺車輪が上下入れ替わりながら地面(33)を走行する一連の動きを説明するものである。下方のピニオン3aは接地側車輪の下辺内側10a上を走行し、上方のピニオン3bは空中に浮いた二辺車輪を前方に送り出すようになる。
【0025】
[図2](a)の階段を昇降する車輪はその直径を大きくするほどピニオンが上段ノンスリップを通過した緩い勾配を登坂することになり上段ノンスリップを中心に公転しやすくなるが、車輪の大部分が車輪の乗ったノンスリップより外にあって下の段に落下しやすい
【0026】
つぎにピニオンが外周内側を移動する円形車輪の昇段に際して車輪後部を押し上げ円形車輪が上段ノンスリップを中心に公転し平坦走行の初期状態に戻ることを可能にする補助装置について説明する。
【0027】
図2の外周内側を移動するピニオンは昇段開始直後に緩く昇段終了直前には急な勾配を登坂する。ピニオンの通過した後方を押し上げれば常時緩い勾配を登坂することになり、ピニオンが上段ノンスリップを通過した後、上段ノンスリップを中心に円形車輪が公転し、容易に平坦走行の初期状態に戻ることが出来る。
【0028】
[図7]は[請求項]の補助装置を[図2] (a)の階段昇降車に適用した例で説明するもので、(a),(b)はそれぞれの補助装置の介助によって、円形車輪が上段に乗り上げて平坦走行の初期状態に戻ろうとする状態を示す。階段を昇降する車輪は車軸を中心に回転するように観えるがノンスリップを中心とする車軸の公転を繰り返しているだけで、1回の車軸の公転で車輪は1回の自転をする。
【0029】
そのため(a)では、ピニオンの外周内側の移動は車輪のノンスリップを中心とする公転を意味し、ピニオンに後続し外周内側を移動する補助車輪の回転角は補助車輪の公転角でピニオンと直径が同じであれば、補助車輪の公転角は車輪の公転角より大きく同軸の補助車輪は加速され先行のピニオンを押しながら車輪後部を押し上げるようになる。
【0030】
またピニオンがモーター歯車でモーターが盤(13)にとりつけばモーターはピニオンの回転と逆方向に自転し補助車輪を押さえつける。(b)では、ピニオンを回転させるモーター歯車がピニオンのまわりを公転しながら後続の補助車輪を押さえつけ円形車輪を引き上げる。
【0031】
補助車輪の踏面への進入角度は最初のノンスリップへの進入時に最大で以後踏面内部へ進入するに従いその進入方向は踏面と平行に近づき後輪後部を押し上げる効果を減少する。
【0032】
[図8](a)はスロープを置いた踏面に補助車輪が進入する状態図で、補助車輪の後輪後部を押し上げる効果の減少をおさえた状態を示す。(b),(c) のそれぞれは(a)と同様の効果をもたらす補助車輪で、(c)は (b) の複数の補助車輪を1つにするだけでなく補助車輪の前半分を省略することで補助車輪の蹴込みに当たるまでの滑走距離を倍増し蹴込みに当たっても車輪のようにピニオンの公転を止めてしまうことはない補助車輪である。
【0033】
(b)の複数個の補助車輪の半径のそれぞれは (a)の スロープを駆け上がる補助車輪が対応するそれぞれの位置での中心と踏面までの距離に一致する。 (c)は補助車輪の形状を渦巻き状にするもので、渦線は等進渦線で、その長さは踏面に接地した長さに同じでその半径は (b)と同様に(a)の スロープを駆け上がる補助車輪が対応するそれぞれの位置での中心と踏面までの距離に一致する。
【0034】
[図9]は車輪に牽引されるソリにこれらの補助車輪を取りつけ車輪の公転時に補助車輪を引き上げることなく車輪本体から切り離し車輪後部の重量を軽減するものである。 (a)に示すソリ(41)は盤後部がガイドローラーを介して乗り上げるとき階段上に停留し公転時に盤後部が離れるとき移動するものである。
【0035】
[図10](a)に示すラチェット刃形状の突起爪(32)には円周の接線方向の底面と半径方向の引掛り面があり、この突起爪を有する車輪が階段のノンスリップに当たる時爪の底面に半径方向の力が作用すると突起爪は車輪内に収納され、爪の引掛り面に円周方向の力が作用するとこれに抵抗し、車輪と階段のノンスリップとが噛合い車輪は滑ることなく登坂する。また接地面ではもっぱら爪の底面に半径方向の荷重が作用するだけなので突起爪は車輪内に収納され引掛り面が地面を引っ掛けることなく、車輪は突起爪を付さない車輪と同様に平坦走行する。(a)は円周を8等分して突起爪を1列にして付した車輪を例示するものであるが、複数列の突起爪を位相をずらして重ね合わすと、ノンスリップと大きく噛合いながら滑ることなく登坂する車輪が可能となる。

Unlike a flat ground, a car is required to measure the shape of a staircase, kick-up, tread, etc. and move accordingly, so it is complicated and expensive to use various sensors. Have used a lot of control devices. The stair lift of the present invention is characterized in that it does not make full use of mode conversion or switching operation of a clutch or the like, and does not require the above-described sensor or control device at all.
[0002]
In other words, when driving flat, the driving gear with the prime mover rotates the driven gear of the wheel, but when the wheel kicks in the stairs, the rotation of the wheel stops and the rotation of the driven gear stops, The drive-side gear revolves around the driven-side gear (or the drive-side gear revolves around the driven-side gear as the rotational speed of the driven-side gear decreases).
[0003]
The stair lift of the present invention uses the revolution of this pinion for the lift operation of the stair lift, and alternately repeats two mode conversions of flat travel and lift operation without using a switching device such as a clutch. .
[0004]
The stair climbing vehicle of the present invention that repeats the rotation of the wheel and the revolution around the stopped wheel has a plurality of wheels intertwined with each other and a pinion attached to the axle on the inner periphery of the wheel inside one wheel. There are two types of the former, one in which the wheels are connected in a chain and the other in which the wheels are arranged radially. As the latter, the shape of the wheel may be a polygon such as a circle or a triangle.
[0005]
Here, if the rotation direction of the wheel and the direction of rotation of the pinion or the wheel coincide with the ascending or descending direction at the time of ascending and descending of the car, the car ascends and descends the stairs.
[0006]
In the stair lift of the present invention, it is absolutely necessary to induce the revolution of the pinion by stopping the rotation of the wheel. To that end, it is inevitable that the wheel does not slip between the non-slip, and various measures are applied to the tire. The
[0007]
In addition, the revolving of the pinion does not continue at the time of ascending, the rear of the wheel is lifted away from the non-slip, the revolving is completed, the wheel starts to rotate, and assistance of auxiliary wheels or the like is required to return to flat running. At the same time, the assistance has the effect of making the part of the concave circle closer to a straight line up or down the track of the axle (pinion center).
[0008]
The movement of the auxiliary wheel that pushes up the rear of the wheel is linked to the revolution of the pinion and it slides under the wheel and slides on the tread. Spiral auxiliary wheels are devised so as not to block.
In order to safely and smoothly lift people and luggage to the upper floor and lower floor, keep the chair and carrier level and prevent the wheels from rotating in the downward direction so that the car does not fall to the lower level. There must be. The present invention utilizes the fact that the suspension material that suspends the chair and the cargo bed keeps the vehicle vertical even when the vehicle body is tilted. It keeps the chair and the loading platform horizontal, and when the vehicle body is tilted, the rotation prevention of the wheels in the descending direction can be solved by hanging the ratchet pawl.
[Brief description of the drawings]
[0009]
First, a description will be given of whether or not the wheel that moves up and down the stairs of the present invention that travels flatly moves up to the stairs without switching operation such as a clutch when the wheel hits a kick. Motor gears rotated by an electric motor or the like rotate the wheel gears to transmit the gears by meshing the gears, and to transmit the rotations via a chain, and when the rotation on the driven side is stopped, the drive side The above-mentioned gears are revolved around the driven-side gears, and the phenomenon of switching from the driven-side rotation to the driving-side revolution is observed when the driven-side rotation stops.

[Fig.2] Wheels that move up and down the stairs in (a) are more likely to revolve around the upper non-slip as the pinion climbs a gentle slope that passes through the upper non-slip as the diameter increases. Is outside the non-slip with the wheel and easily falls to the lower stage .
[0026]
Next, a description will be given of an auxiliary device that pushes up the rear portion of the wheel when the pinion moves up on the inner side of the outer periphery and makes the circular wheel revolve around the upper non-slip and return to the initial state of flat running.
[0027]
The pinion that moves inside the outer periphery of FIG. 2 loosens immediately after the start of climbing, and climbs a steep slope just before the end of climbing. If you push up behind the pinion, it will always climb a gentle slope, and after the pinion passes the upper non-slip, the circular wheel revolves around the upper non-slip, and it can easily return to the initial state of flat running I can do it.
[0028]
[ FIG. 7 ] illustrates an example in which the auxiliary device of [Claim 2 ] is applied to the stair climbing vehicle of [FIG. 2] (a), and (a) and (b) are supported by the assistance of each auxiliary device. The state where the circular wheel rides on the upper stage and tries to return to the initial state of flat running is shown. Although the wheel that goes up and down the stairs appears to rotate around the axle, the wheel rotates once by the revolution of the axle only by repeating the revolution of the axle around the non-slip.
[0029]
Therefore, in (a), the movement of the pinion inside the outer periphery means a revolution centering on the non-slip of the wheel, and the rotation angle of the auxiliary wheel that moves following the pinion and moves inside the outer periphery is the revolution angle of the auxiliary wheel and the diameter of the pinion and the pinion. If they are the same, the revolution angle of the auxiliary wheel is larger than the revolution angle of the wheel, and the coaxial auxiliary wheel is accelerated to push up the rear part of the wheel while pushing the preceding pinion.
[0030]
If the pinion is a motor gear and the motor is attached to the board (13), the motor rotates in the opposite direction to the rotation of the pinion and presses the auxiliary wheel. In (b), the motor gear for rotating the pinion revolves around the pinion and presses the subsequent auxiliary wheel to raise the circular wheel.
[0031]
The approach angle of the auxiliary wheel to the tread surface is the maximum at the time of the first non-slip approach, and the approach direction becomes parallel to the tread surface and decreases the effect of pushing up the rear wheel rear portion as it subsequently enters the tread surface.
[0032]
[ FIG. 8 ] (a) is a state diagram in which the auxiliary wheel enters the tread surface on which the slope is placed, and shows a state in which the effect of pushing up the rear rear portion of the auxiliary wheel is suppressed. Each of (b) and (c) is an auxiliary wheel that has the same effect as (a). (c) is not only a single auxiliary wheel in (b), but also omits the front half of the auxiliary wheel. By doing so, even if the sliding distance until it hits the kick of the auxiliary wheel is doubled and hits the kick, it does not stop the revolution of the pinion like the wheel.
[0033]
Each of the radii of the plurality of auxiliary wheels in (b) corresponds to the distance from the center to the tread surface at each position corresponding to the auxiliary wheel running up the slope in (a). (c) shows the shape of the auxiliary wheel in a spiral shape, the vortex line is an isometric vortex line, the length of which is the same as the length touching the tread, and the radius is the same as (b). Auxiliary wheels running up the slope of the road correspond to the distance from the center to the tread at each corresponding position.
[0034]
[ FIG. 9 ] attaches these auxiliary wheels to a sled pulled by the wheel and separates them from the wheel body without raising the auxiliary wheel when the wheel revolves, thereby reducing the weight of the rear part of the wheel. The sled (41) shown in (a) stops when the rear part of the board rides on the guide roller and stops on the stairs and moves when the rear part of the board leaves at the time of revolution.
[0035]
[ FIG. 10 ] The ratchet blade-shaped protrusion claw (32) shown in (a) has a circumferential tangential bottom surface and a radial hooking surface, and the claw when the wheel having the protrusion claw hits a non-slip of the staircase. When a radial force is applied to the bottom surface of the wheel, the projecting claw is stored in the wheel, and when a circumferential force is applied to the catching surface of the claw, it resists this, and the wheel and the non-slip of the stairs mesh and the wheel slides. Climb without climbing. Also, since the load on the ground surface is only subjected to a radial load on the bottom surface of the claw, the projection claw is housed in the wheel and the catching surface does not catch the ground, and the wheel runs flat like a wheel without the projection claw. To do. (A) is an example of a wheel with the circumference divided into eight equal parts and the projection claws arranged in one row. When a plurality of rows of projection claws are overlapped while shifting the phase, Wheels can be climbed without slipping.
