車椅子や荷物運搬台車などで段差や階段を昇降するための装置として、引用文献1~2に階段昇降装置などが開示されているが、引用文献1の階段昇降装置では、地面と接触する鉛直部材が8本必要であり、また、引用文献2の脚車輪移動装置では、地面と接触する鉛直部材が最低6本必要なものとなっている。 Cited Documents 1 and 2 disclose a stair climbing device and the like as a device for going up and down steps and stairs with a wheelchair, a luggage carrier, etc. However, the stair climbing device of Cited Document 1 does not include a vertical member that contacts the ground. are required, and the leg wheel moving device of Cited Document 2 requires at least six vertical members that come into contact with the ground.

本発明は、車椅子や荷物運搬台車などで段差や階段を昇降するための装置であり、地面と接触する鉛直部材が最低4本のシンプルな構造とすることができる、段差昇降装置を提供するものである。 The present invention is a device for ascending and descending steps and stairs with a wheelchair, a luggage carrier, etc., and provides a step ascending and descending device that can have a simple structure with at least four vertical members that come into contact with the ground. is.

車椅子や荷物運搬台車などに設置する装置であって、互いに並行でそれぞれ独立に水平方向へ張出格納可能な少なくとも4本のアーム1と、前記少なくとも4本のアーム1のそれぞれの張出方向先端付近に配置するそれぞれ独立に鉛直方向へ移動または伸縮可能な脚2と、を備え、前記少なくとも4本のアーム1は少なくとも2本ずつ反対方向へ張り出すように配置することを特徴とする、段差昇降装置とする。 A device to be installed in a wheelchair, a luggage carrier, or the like, comprising at least four arms 1 parallel to each other and capable of independently extending and retracting in the horizontal direction, and tips in the extension directions of the at least four arms 1. legs 2 arranged near each other and independently movable or extendable in the vertical direction, and at least two of the at least four arms 1 are arranged so as to protrude in opposite directions. Elevator device.

各アーム1と各脚2を順番に動作することにより段差や階段を昇降することができる。一例として、車椅子での階段昇り時における具体的動作順の例を図1(a)~(d)を用いて説明する。
1.階段下側のアーム1C、1Dを格納状態で脚2C、2Dを接地し、階段上側のアーム1A、1Bを張出状態で2A、2Bを接地する(a)。
2.脚2A~Dを同時に伸ばして車椅子を持ち上げ、アーム1C、1Dを張り出しながらアーム1A,1Bを格納して、車椅子を平行移動する(b)。
3.脚2A~Dを同時に縮めて車椅子の片方の車輪を接地させ、アーム1Dを格納して脚2Dを接地する(c)。
4.アーム1Cを格納して脚2Cを接地する。アーム1C、1Dを格納する時において、脚2C、2Dは、アーム1C、1Dを動かすことができる最低限の縮め量とすることが安全上重要である。また、アーム1Dの格納とアーム1Cの格納の順序は逆でもよい。
5.脚1A、1Bを縮めて、アーム1A、1Bを張出状態にして、脚2A、2Bを接地する(d)。
上記1~5の繰り返しにより段差や階段を昇ることができる。また、上記の動作の概ね逆の動作を行うことで、段差や階段を降りることができる。
By sequentially operating each arm 1 and each leg 2, steps and stairs can be ascended and descended. As an example, an example of a specific operation order when climbing stairs in a wheelchair will be described with reference to FIGS. 1(a) to (d).
1. Legs 2C and 2D are grounded while arms 1C and 1D on the lower side of the stairs are retracted, and arms 2A and 2B are grounded by extending arms 1A and 1B on the upper side of the stairs (a).
2. The legs 2A to 2D are extended at the same time to lift the wheelchair, and the arms 1C and 1D are extended while the arms 1A and 1B are retracted to move the wheelchair in parallel (b).
3. Legs 2A-D are retracted at the same time to ground one wheel of the wheelchair, arm 1D is retracted and leg 2D is grounded (c).
4. The arm 1C is retracted and the leg 2C is grounded. When retracting the arms 1C and 1D, it is important for safety that the legs 2C and 2D are shrunk to the minimum amount that allows the arms 1C and 1D to move. Also, the order of retracting the arm 1D and the retracting of the arm 1C may be reversed.
5. The legs 1A and 1B are contracted to extend the arms 1A and 1B, and the legs 2A and 2B are grounded (d).
Steps and stairs can be climbed by repeating steps 1 to 5 above. Also, by performing an operation that is generally the reverse of the above operation, it is possible to go down a step or a staircase.

車椅子や荷物運搬台車などに設置する装置であって、互いに並行でそれぞれ独立に水平方向へ張出格納可能な少なくとも4本のアーム1と、前記少なくとも4本のアーム1のそれぞれの張出方向先端付近に配置するそれぞれ独立に鉛直方向へ移動または伸縮可能な脚2と、を備え、前記少なくとも4本のアーム1は少なくとも2本ずつ反対方向へ張り出すように配置することを特徴とする、段差昇降装置とする。 A device to be installed in a wheelchair, a luggage carrier, or the like, comprising at least four arms 1 parallel to each other and capable of independently extending and retracting in the horizontal direction, and tips in the extension directions of the at least four arms 1. legs 2 arranged near each other and independently movable or extendable in the vertical direction, and at least two of the at least four arms 1 are arranged so as to protrude in opposite directions. Elevator device.

図2に、本段差昇降装置を車椅子に取り付けた実施例1を示す。実施例1では、車椅子の背面と膝裏部分にそれぞれ2本ずつのアーム1を配置している。アーム1は人手によるスライド動作構造とし、脚2はギヤードモータとラック・ピニオンによる電動駆動としている。それぞれの脚2は容易に取り外すことができ、本段差昇降装置を使用しないときの車椅子使用への影響を小さくしている。 FIG. 2 shows Embodiment 1 in which the step-climbing device is attached to a wheelchair. In Example 1, two arms 1 are arranged on the back of the wheelchair and on the back of the knees. The arm 1 is designed to be slid by hand, and the leg 2 is electrically driven by a geared motor and a rack and pinion. Each leg 2 can be easily removed to reduce the influence on the use of the wheelchair when the step climbing device is not used.

図3に、本段差昇降装置を荷物運搬台車に取り付けた実施例2を示す。実施例2では、荷物運搬台車の前後端付近にそれぞれ2本ずつのアーム1を配置している。アーム1は人手によるスライド動作構造とし、脚2はギヤードモータとラック・ピニオンによる電動駆動としている。それぞれの脚2は容易に取り外すことができ、本段差昇降装置を使用しないときの荷物運搬台車使用への影響を小さくしている。 FIG. 3 shows a second embodiment in which the step lifting device is attached to a cargo carrier. In the second embodiment, two arms 1 are arranged near the front and rear ends of the luggage carrier. The arm 1 is designed to be slid by hand, and the leg 2 is electrically driven by a geared motor and a rack and pinion. Each leg 2 can be easily removed to reduce the influence on the use of the luggage carrier when the step lifting device is not used.

実施例1や実施例2では、構造の単純化のため、アーム1の動作を人手で行うものとしているが、アーム1の動作を、例えばギヤードモータとラック・ピニオンによる電動駆動などとすることもできる。アーム1と脚2を電動駆動など人手が不要な駆動方法とした場合、近接センサや水平センサなどの各種センサや演算装置を用いることにより、アーム1と脚2の自動制御動作が可能となる。 In Embodiments 1 and 2, the movement of the arm 1 is performed manually for the sake of structural simplification, but the movement of the arm 1 may be electrically driven by, for example, a geared motor and a rack and pinion. can. If the arm 1 and the leg 2 are driven by an electric drive method that does not require human intervention, the arm 1 and the leg 2 can be automatically controlled by using various sensors such as a proximity sensor and a horizontal sensor, and an arithmetic device.

アーム1や脚2の駆動方法としては、前記のようなギヤードモータとラック・ピニオンによる電動駆動のほか、電動シリンダや油圧シリンダなどによる駆動方法も考えられる。 As a method for driving the arm 1 and the leg 2, in addition to the electric drive using the geared motor and the rack and pinion as described above, a drive method using an electric cylinder, a hydraulic cylinder, or the like is also conceivable.

本段差昇降装置におけるアーム1の最小構成は4本であるが、構造の複雑化を許容して5本以上とすることで、安全性の向上や適応荷重の増加を期待できる。 Although the minimum configuration of the arms 1 in this step-lifting device is four, if the number of arms 1 is increased to five or more to allow for complication of the structure, improvement in safety and increase in adaptive load can be expected.

図2~3に示した実施例1~2は、本発明の実施例に過ぎず、アーム1や脚2の構造・形状・配置位置・本数、本段差昇降装置の取り付け対象・取付位置、等を限定するものではない。また、図1に示した動作順の例は、本発明の動作実施例に過ぎず、アーム1や脚2の動作順を限定するものではない。 Embodiments 1 and 2 shown in FIGS. 2 and 3 are merely embodiments of the present invention, and include the structure, shape, arrangement position, and number of the arms 1 and legs 2, the mounting target and mounting position of the step climbing device, and the like. is not limited to Moreover, the example of the operation order shown in FIG. 1 is merely an operation example of the present invention, and does not limit the operation order of the arm 1 and the leg 2 .

本段差昇降装置は、平地では車輪移動ができる車椅子や荷物運搬台車などに取り付けることが好適であるが、家庭内での階段昇降など、平地での車輪移動を必要としないで段差や階段を昇降できるだけでよい場合には、普通の椅子に取り付けることも考えられる。 This step-climbing device is suitable to be attached to a wheelchair or luggage carrier whose wheels can be moved on flat ground. If possible, it is also conceivable to attach it to an ordinary chair.
