Description

本発明は、歩行者が階段や通路を移動する際に、肉体的負担を軽減し安定した移動を補助する自走手摺に関するものである。 The present invention relates to a self-propelled handrail that reduces the physical burden on pedestrians and assists them in stable movement when moving on stairs or passageways.

従来から自宅や施設に於いて、階段を昇降する際の肉体的負担を軽減する手段として、エレベーターや電動機付昇降台等が用いられてきた。しかしこれらの導入には数百万円以上の費用がかかり、多くの設置スペースを必要とするなど、気軽に導入できるものではなかった。 BACKGROUND ART Elevators, motorized lifts, and the like have been used in homes and facilities as a means of reducing the physical burden of going up and down stairs. However, these systems were not easy to implement, as they cost several million yen or more and required a large amount of installation space.

足腰が不自由な人を対象に開発された、階段に設置する電動機付昇降台は、備え付けの座椅子に座ることにより、自動で階段の昇降が可能である。しかし足腰が健全な健常者にとって、肉体的負担を軽減し安定した移動を補助するのに、座椅子による補助は十分過ぎるばかりか、座椅子分の設置費用が高価で、且つ設置により階段のスペースを圧迫するという欠点が生じる。 A motorized climbing platform installed on stairs, developed for people with mobility issues, allows people to automatically go up and down the stairs by sitting on the built-in seat. However, for healthy people with healthy legs and hips, the support provided by a seat chair is not only sufficient to reduce the physical burden and assist stable movement, but the installation cost for the seat chair is expensive, and the installation requires stairs. The disadvantage is that it takes up space.

健常者が階段を昇降する際に肉体的な負担を軽減する手段として、例えば特許文献1に記載のレール式手摺昇降機があり、手摺を握って階段を昇降することで肉体的負担を軽減できる。これらは先述した電動機付昇降台より設置スペースもコンパクトとなっている。しかし電動機を高い位置に設置し、手摺にロープを固定して引っ張る仕組みのため、電動機を別途設置する手間や費用がかかり、且つ曲線階段で容易に使用することができないという欠点が生じる。 As a means for reducing the physical burden when an able-bodied person goes up and down stairs, there is a rail-type handrail lift described in Patent Document 1, for example, and the physical burden can be reduced by holding the handrail and going up and down the stairs. These have a more compact installation space than the motorized lift mentioned above. However, because the electric motor is installed at a high position and the rope is fixed to the handrail and pulled, there are disadvantages in that it requires the effort and expense of separately installing the electric motor, and it cannot be easily used on curved stairs.

特許文献2に記載の自動手摺移動機も、同様のレール式手摺昇降機であるが、手摺がベルト式となっているため、レール側にベルトを摺動させる構造が必要で、レール自体の構造が複雑となる。またこの機器についても曲線階段で容易に使用することができないという欠点が生じる。 The automatic handrail moving machine described in Patent Document 2 is a similar rail-type handrail elevator, but since the handrail is a belt type, a structure for sliding the belt on the rail side is required, and the structure of the rail itself is It becomes complicated. Another disadvantage of this device is that it cannot be easily used on curved stairs.

特許文献3に記載の人や重量物の昇降補助装置のようにスプリング力により階段を上る装置があるが、前述と同様に曲線階段で容易に使用ができないだけでなく、階段を下りる時に、手摺をスライドさせてスプリング力をかけなければならないという欠点が生じる。 There are devices that use spring force to climb stairs, such as the lifting aid for people and heavy objects described in Patent Document 3, but as mentioned above, not only can they not be easily used on curved stairs, but they also cannot be used easily when going down stairs. The disadvantage is that the spring force must be applied by sliding the spring.

以下、図1~6を参照して説明する。自走手摺は、レールをガイドにレール上を走行する、モーターと一体化した手摺本体を備える。レールは、人の移動方向に沿って延び、階段、スロープ、通路の横に配置された壁面等に設けても良いし、レールを取り付けるための支柱を床又は地面に設けても良い。図1は階段等の側に取り付けるレールと手摺本体で構成される。 This will be explained below with reference to FIGS. 1 to 6. A self-propelled handrail includes a handrail body that is integrated with a motor and runs on the rail using a rail as a guide. The rails extend along the direction of movement of people and may be provided on stairs, slopes, walls placed next to passageways, etc., or supports for attaching the rails may be provided on the floor or the ground. Figure 1 consists of a rail that is attached to the side of a staircase, etc., and a handrail body.

レールはアルミフレーム1とラックギア2とリミットスイッチ作動ボルト3で構成される。また手摺本体は、電磁ブレーキ付ギヤードモーター4と、電磁ブレーキ付ギヤードモーター4に取り付けラックギア2と噛み合うギア7と、レールとして機能するアルミフレーム1の平坦な面をガイドして手摺本体の動作を補助するための合計16個のローラーフォロアー8と、レール側のリミットスイッチ作動ボルト3で作動して停止するリミットスイッチ6と、持ち手9と作動スイッチ11と停止スイッチ10と手摺本体の前進・後退を選択する選択スイッチ12と、荷物をかけるフック13とリレーなどの電気部品を収納する制御ボックス5で構成される。電気はコンセントなどから供給しても良いし、手摺本体に設けた電池から供給しても良い。本実施形態に係る自走手摺は、何れも安価で単純な構成となっている。図1に示すように、人は手摺本体から吊り下げられた持ち手9を握り、またフック13に荷物をかけて階段を上ることで、肉体的負担を軽減し安定した移動を補助する。ただし、これに限られず、例えば、人が手摺本体をつかんで使用するものとしても良い。この場合、停止スイッチ10、作動スイッチ11、選択スイッチ12、フック13は、手摺本体に設けても良い。 The rail is composed of an aluminum frame 1, a rack gear 2, and a limit switch operating bolt 3. In addition, the handrail body is made up of a geared motor 4 with an electromagnetic brake, a gear 7 attached to the geared motor 4 with an electromagnetic brake that meshes with the rack gear 2, and a flat surface of an aluminum frame 1 that functions as a rail to guide the movement of the handrail body. A total of 16 roller followers 8, a limit switch 6 that is operated and stopped by the limit switch operating bolt 3 on the rail side, a handle 9, an operating switch 11, a stop switch 10, and a handrail body that moves forward and backward. It is composed of a selection switch 12 for selection, a hook 13 for hanging luggage, and a control box 5 for storing electrical parts such as relays. Electricity may be supplied from an outlet or the like, or from a battery installed in the handrail body. All of the self-propelled handrails according to this embodiment are inexpensive and have a simple configuration. As shown in FIG. 1, a person grasps a handle 9 hanging from the handrail body, hangs luggage on a hook 13, and climbs the stairs, thereby reducing physical burden and assisting in stable movement. However, the present invention is not limited to this, and, for example, it may be used by a person grasping the handrail body. In this case, the stop switch 10, the activation switch 11, the selection switch 12, and the hook 13 may be provided on the handrail body.

人が階段を上る時、荷物をフック13に掛け、持ち手9を握り、選択スイッチ12で上り側を選択し、作動スイッチ11を押すと、手摺は電磁ブレーキ付ギヤードモーター4が作動し、ギア7が回転するとラックギア2と噛み合い、階段の上り方向に移動する。電磁ブレーキ付ギヤードモーター4は内蔵ギアヘッドにより減速し、移動速度0.5~1.0m/s程度にするのが好適である。 When a person goes up the stairs, he or she hangs the luggage on the hook 13, grasps the handle 9, selects the upward side with the selection switch 12, and presses the activation switch 11.The geared motor 4 with an electromagnetic brake operates to move the handrail. When 7 rotates, it engages with the rack gear 2 and moves in the upward direction of the stairs. The geared motor 4 with an electromagnetic brake is preferably decelerated by a built-in gear head to a moving speed of about 0.5 to 1.0 m/s.

電気回路はリレーとリミットスイッチ6を用い、図6に示すように階段の上りと下りの移動を自己保持回路で行う。 The electric circuit uses a relay and a limit switch 6, and as shown in FIG. 6, movement up and down the stairs is performed by a self-holding circuit.

手摺本体が人の手を引きながら移動するため、人は階段昇降時の肉体的負担を軽減でき、荷物を持つ必要もない。 Since the handrail itself moves while guiding the person's hand, the person can reduce the physical strain of going up and down stairs, and there is no need to carry luggage.

階段の途中で手摺本体を停止する時は、停止スイッチ10を押すことで非常停止が作動し停止する。停止中は電磁ブレーキ付ギヤードモーター4の電磁ブレーキにより停止位置は保持される。停止した手摺本体は作動スイッチ11により再開する。 When stopping the handrail body in the middle of the stairs, pressing the stop switch 10 activates the emergency stop and stops the handrail body. While stopped, the stopped position is maintained by the electromagnetic brake of the geared motor 4 with electromagnetic brake. The stopped handrail body is restarted by the activation switch 11.

手摺本体が階段を上りきると、リミットスイッチ作動ボルト3が上り側のリミットスイッチ6を作動させ、自動で停止する。 When the handrail body reaches the top of the stairs, the limit switch activation bolt 3 activates the limit switch 6 on the upward side, and the handrail body automatically stops.

階段を下る場合は、上りと逆の作業となる。 Going down the stairs is the opposite of going up.

曲線階段のように、レールを曲げて設置する場合、アルミフレーム1は予め曲がったメーカー標準品を使用するのがコスト面で好適であるが、ベンダー等により曲線状に曲げ加工したものでも良い。ラックギア2は、フレキシブルタイプのものを使用し、アルミフレーム1の長手方向に延びる溝部に嵌め込むのが好適である。手摺本体が曲線を移動時、図5に示すように半径300mmの曲線を描いたレールの場合、直線移動時に比べ、本体側とレール側のギア同士の隙間に2.68ミリのギャップが生じる。そのためレールを曲げて設置する場合は、ギャップを見込んでアルミフレーム1の平坦部とラックギア2の取り付け位置を直線時より2.68ミリ離すことでギャップを回避する。 When installing the rails by bending them as in a curved staircase, it is preferable to use a pre-bent manufacturer's standard product for the aluminum frame 1 in terms of cost, but it may also be bent into a curved shape by a bender or the like. It is preferable that the rack gear 2 is of a flexible type and is fitted into a groove extending in the longitudinal direction of the aluminum frame 1. When the handrail body moves along a curve, as shown in Figure 5, in the case of a rail with a radius of 300 mm, there is a gap of 2.68 mm between the gears on the body side and the rail side, compared to when it moves in a straight line. Therefore, when installing the rail with a bend, the gap can be avoided by allowing for a gap and setting the flat part of the aluminum frame 1 and the mounting position of the rack gear 2 2.68 mm apart from when it is straight.

近年都心では土地価格が上がり、狭い土地を活用するために3階建て住宅の需要が増えつつある。3階建て住宅を建築する時、階段昇降時の肉体的負担を軽減するため、エレベーターを設置したいと思うが、数百万円の設置費用と各階に2畳程度の設置スペースが必要となるため、設置のハードルが高く断念するケースが多々見られた。一方で自走手摺は、階段の側にレールを設置し、最低1台の手摺本体があれば、階段昇降時の肉体的負担が省スペース且つ格安に解決する。 In recent years, land prices have risen in central Tokyo, and demand for three-story houses is increasing to make better use of small plots of land. When building a three-story house, I would like to install an elevator to reduce the physical strain of going up and down the stairs, but this would require installation costs of several million yen and an installation space of about 2 tatami mats on each floor. There were many cases where the installation hurdles were too high and people gave up. On the other hand, with self-propelled handrails, if a rail is installed on the side of the stairs and there is at least one handrail body, the physical burden of going up and down the stairs can be solved in a space-saving and inexpensive manner.
