Description

【0001】
【発明の属する技術分野】
従来から車いすや乳母車などの軽車両では比較的幅の狭い車輪が使用されているため、砂地や砂利道、雪道や石畳道などを走行する際には、車輪が砂や砂利、雪に埋まったり、石畳の隙間に挟まったりしてスムーズな走行に困難があった。本発明は、軽車両がそのような砂地や砂利道、雪道、石畳道などに遭遇した場合においても、簡単な補助器具を着脱自在に取り付けることによって走行を可能にした軽車両の走行補助装置に関するものである。
【0002】
【従来の技術】
従来、例えば特開2000‐038138「車いすの雪上運搬用そり」のように、雪道において車いす全体を「そり」に載せて雪上を運搬するものが提案されている。また近年、砂浜を走行するためにゴムチューブないし発泡プラスチック製などの幅広の車輪を使用することによって車輪の接地面積を広くし、車輪が砂浜に埋まることなく走行できるようにしたレジャー志向の軽車両が提案されている。
【0003】
【発明が解決しようとする課題】
以上のように提案されている「雪上運搬用そり」やレジャー用車両においては、いずれも機能及び用途が極めて限られており、また運搬に困難が伴ったりして、非常に使い勝手の悪いものであった。例えば「そり」を使用するものは、「そり」自体がかさばるため運搬に困難が伴うほか、雪上以外には実質的に使用できないものである。またゴムチューブや発泡プラスチック製などの幅広の車輪を使用した車両は、車輪自体が特殊なものであるために舗装道路などの通常の走行時はかえって使用に困難を伴い、走行する路面の種類によってその都度車輪の交換をしなければならない問題がある。またそのような特殊な車輪に適合させるために、車体構造も特殊なものにする必要があるほか、特殊な車輪であるために車輪自体でも生産コストがかさむという難点があった。
【0004】
本発明は、このような従来の走行装置の構成が有していた諸問題を解決するものであり、車いすや乳母車など一般に販売されている軽車両に適用が可能な走行補助装置を提供するものである。舗装道路など通常の走行をするときの機能はそのままで、砂地や砂利道、雪道、石畳道などの特殊な路面に遭遇した場合に、簡単な構成の安価な補助器具を着脱自在に装着することによって、特殊路面でも走行可能とした軽車両の走行補助装置を実現したものである。
【0005】
【課題を解決するための手段】
本発明は、上記の目的を達成するために、幅広の外輪部材を車いすなど軽車両の車輪に沿って簡単に着脱自在に取り付けるようにした走行補助装置である。砂利道や砂地などの特殊路面の走行時には外輪部材を装着し、通常走行時には再び取り外しできるようにした。この走行補助装置は、軽車両の車輪の幅よりも広い幅を持つ外輪部材を車輪外周に取り付けることによって接地面積を大きくしたので、車輪が砂や砂利に埋まることを解消できる。この外輪部材は構造が簡単で軽く、かさばることがないので持ち運びが容易であるだけでなく、生産コストも安価とすることが可能である。またこの走行補助装置はその構成上、搭乗者や荷物が車両に乗ったままで装置を着脱できる特徴を有している。従って例えば車いすに適用した場合、着脱時に搭乗者が車いすからわざわざ降りることを必要とせず、身体障害者やお年寄りには勿論のこと、乗降を手助けする介助者にも優しい手段を提供できるものである。
【0006】
【発明の実施の形態】
以下、本発明にかかる軽車両の走行補助装置の好ましい実施形態の一例として、車いすに適用した場合を詳細に説明する。
【0007】
図1は本発明の走行補助装置を車いすの後輪に装着した状態の概略図である。車いす本体1の後輪2に外輪部材3を装着している。図2は側面図である。4つの車輪を持つ一般的な軽車両では、本発明の走行補助装置は4つの車輪すべてに装着するのがよいが、車いすでは荷重の大半が後輪にかかっているので、走行補助装置は後輪に装着することでも有効である。
【0008】
図3は本発明の走行補助装置の一実施例を示したもので、半円弧状の外輪部材3を二つ合わせて円弧状に連結することによって、本発明の走行補助装置を構成している。3cは二つの外輪部材を連結する連結具の一例を示すが、複数の部材を連結するものであればその手段は問わない。
【0009】
図4は、車いすの後輪2に外輪部材3を装着した状態の断面図であり、搭乗者自身が駆動するための手動操作用リング4を備えた後輪に装着した例を示している。後輪2を被覆する被覆部3aは、手動操作用リング4の形状に合わせて形成され、外輪部材を車輪にしっかりと固定し外輪部材が車輪から外れることを防止している。なお、本実施例では被覆部3aを後輪のタイヤ部分もすっぽり覆ったものとしているが、外輪部材の接地面がタイヤの接地面と面が揃うように、手動操作用リング4に外輪部材を装着することでもよい。勿論、手動操作用リングを持たないタイプの車いすでは、車輪の形状に合わせて被覆部3aを形成することが必要である。さらに被覆部3aの外側に接地部(面)3bが形成されているが、これは直接路面に接する部分であるため路面にそった平面状にするのが好ましく、また多少強度を持たせるのがよい。なお、図4は、砂利道や石畳道などの走行時の乗り心地を改善するために、外輪部材3の接地面3bに緩衝用のゴム3dを貼り付けた例を示すものである。
【0010】
この実施例における走行補助装置の実際の装着手順は、次のようである。まず、半円弧状の外輪部材3の一方を後輪2に仮装着したのち、車いすを後輪半回転分ほど前進させて残りの外輪部材3を仮装着し、最後に連結具3cによって二つの外輪部材を連結する。介助者によってこの作業が行なわれれば、搭乗者はわざわざ車いすから降りる必要がなく本走行補助装置を装着することができる。走行補助装置を取り外す場合も同様である。
【0011】
図5は、帯状で可撓性のある外輪部材の概略図で、本発明の走行補助装置におけるもう一つの実施例を示している。材質としては、例えばゴム、プラスチック等が考えられる。これは車輪2を包むように被覆部3aを形成し、被覆部3aの外側に平面状の接地部(面)3bを形成している。被覆部3aは車輪2に巻きつける関係上、適当なピッチで相応の切り欠き3eを設けている。この実施例における実際の装着の手順は、まず帯状の外輪部材3を接地部3bが下になるように進行方向に向けて路面に置き、車いすを前進させて外輪部材3の上に後輪2が重なるようにしたのち、被覆部3aが車輪2を包むように後輪の外周に沿って巻きつけるようにして両端をそろえ、連結する。介助者が作業を行なうことによって、搭乗者がわざわざ車いすから降りる必要がなく、本走行補助装置を装着できる点は前記の実施例と同様である。
【0012】
次に本発明の走行補助装置の車いすにおける使用方法を説明する。車いすが砂地や砂利道に遭遇した際、介助者が前述のごとく車いすの後輪に本発明の走行補助装置を装着する。その後、介助者は車いすの取っ手を少し押し下げて前輪を浮かすようにし、前輪が浮いた状態で車いすを前進させて砂地や砂利道を走行する。後輪は幅の広い外輪部材によって接地面積が大きくなっており、砂や砂利に車輪を取られることなく進むことができる。
【0013】
上記のような使用では車いすが後輪のみで支えられることから、不安定であることは否めない。したがって、砂地や砂利道が長い距離にわたるなどして搭乗者と介護者の双方に負担がかかるなど、より車いすを安定させることが求められる場合の対応手段について以下に説明する。
【0014】
図6は、車いすの前輪5を台車6に懸架した状態の概略図、図7はその側面図を示している。一般に市場で販売されている車いすは、方向切り換えの機能を持たせるために前輪4をキャスター構造にしているものが多く、小径の車輪を使用している例が多いが、その前輪5が地面から浮くほどの高さの台車6を使用する。図8はその台車構造の概略を示すもので、1は車いす本体であり、台車6に車いす本体1を取り付けることができるようにしている。台車6の車輪7は、もとの車いすの前輪5より幅が広い車輪を使用することによって車輪が砂地や砂利道に埋まらないものとした。本実施例ではその台車6にロープ8を結んだものである。
【0015】
この台車6を使用した場合の使用方法を説明する。まず、前述のように車いすの後輪2に走行補助装置を装着し、その後、前輪部分5を持ち上げて台車6に懸架する。前方への走行は、通常通りに介助者が後方から押し進めるか、台車6に結ばれたロープ8を介助者が車いすの前方から牽引することによって行なう。車いすは4輪で支えられているので不安定になることはなく、また台車の車輪7は幅広なので砂地や砂利道、雪道などに車輪が埋まることなく走行することができる。
【0016】
以上、車いすの前輪部分を安定させる手段として台車による実施例を説明したが、他の実施例としては、台車に代えて「そり」を使用することも可能である。前輪に対する荷重は小さいので、路面との摩擦係数が高くなることはなく、雪道のみならず砂地でも走行が可能である。また、リヤカーや昔の人力車のように、車いすの前方から車両を牽引することができる「牽引ハンドル」を車いす本体に着脱可能に取り付けることで前輪部分を地面から浮かせて走行することも考えられる。
【0017】
【発明の効果】
本発明の軽車両の走行補助装置は、以上に説明した構成から下記に記載する効果を有するものである。
【0018】
本発明装置では、外輪部材によって路面に対し広い接地面積を確保することが可能である。従って、車いすや乳母車の軽車両における幅の小さい車輪では、砂地、砂利道、雪道や石畳道に埋まったり溝に嵌ったりして走行が困難になっていた問題があったが、これを解消することができ、軽車両をそのような特殊路面でも楽に走行できるようにしたものである。
【0019】
本発明装置では、軽車両の側に何ら構造上の変更を要求することなく、走行補助装置の側のみで解決するものである。従って例えばJIS規格に基づいて生産された一般的な車いすに適合するように外輪部材を構成することにより、どの車いすにも適用できる汎用的な手段として提供できるものである。
【0020】
本発明装置を構成する外輪部材は簡単な構成なので、生産コストも安価とすることが可能である。JIS規格に基づいた車いすに適合するように外輪部材を構成すれば大量生産も可能となる。従って、身体障害者やお年寄りに大きな経済的負担をかけることなく、広く利用してもらうことが可能である。
【0021】
本発明装置では、装置を構成する外輪部材は構造が簡単で軽く、かさばることがないので持ち運びも容易である。しかも車両が通常の走行態勢のままで簡単に走行補助装置を装着することができる。従って、例えば車いすにおいては、介助者によって必要な時に簡単に装置を車いすに着脱できるので、車いすで出かける際に問題となるバリアの一つの解消に貢献できるものである。
【0022】
この走行補助装置はその構成上、身体の不自由な人やお年寄り、或いは荷物を車両に乗せたままで装置を着脱できることに特徴がある。車いすの場合にあっては、着脱時に搭乗者が車いすからわざわざ降りる必要がない。身体障害者やお年寄りに優しく、かつ乗降を手助けしなければならなかった介助者にも優しい手段を提供するものである。
【0023】
近年、身体の不自由な人達のアウトドア志向が高まっている。今までは海岸に出かけることに対して介助機器と介助体制との両面で非常な困難が存在していたが、本発明による車いすの走行補助装置は、介助者に格別の負担をかけることなく、車椅子に乗ったままで海岸の砂浜に乗り入れることを可能にしたものである。本発明の走行補助装置は身体の不自由な人達にとって、明るい1ページを開くものと云って過言ではない。
【0024】
車いすの後輪に走行補助装置を取り付けることだけでも以上のような効果が存在するが、車いすの前輪部分を台車に懸架すれば走行時の車両を安定させることが可能である。そのため介助者のサポートがあれば、海岸の砂浜などでのレジャーにも適合することを可能とし、身体の不自由な人達のアウトドア活動にも有効に活用することができる。

TECHNICAL FIELD OF THE INVENTION
Conventionally, relatively narrow wheels are used in light vehicles such as wheelchairs and baby carriages, so when traveling on sandy ground, gravel roads, snowy roads, cobblestone roads, etc., the wheels are buried in sand, gravel, snow. There was a difficulty in running smoothly due to the gap between the stone pavements. The present invention relates to a travel assist device for a light vehicle that enables a light vehicle to run by detachably attaching a simple auxiliary device even when the light vehicle encounters such a sandy land, a gravel road, a snowy road, a cobblestone road, or the like. It is about.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, for example, Japanese Patent Laid-Open Publication No. 2000-38138, entitled "Sleigh for transporting wheelchairs on snow", has been proposed that transports the entire wheelchair on a sled on snowy roads. In recent years, leisure-oriented light vehicles have increased the ground contact area of wheels by using wide wheels such as rubber tubes or foam plastics to run on sandy beaches so that they can run without being buried in sandy beaches. Has been proposed.
[0003]
[Problems to be solved by the invention]
In the "sleigh for snow transport" and the leisure vehicles proposed as described above, the functions and applications are extremely limited, and the transport is difficult, making it extremely inconvenient. there were. For example, those using a "sleigh" are difficult to transport because the "sleigh" itself is bulky, and cannot be used except for snow. In addition, vehicles using wide wheels such as rubber tubes and foamed plastic are difficult to use during normal running on paved roads because the wheels themselves are special, and depending on the type of road surface running There is a problem that the wheel must be replaced each time. In addition, in order to adapt to such special wheels, it is necessary to make the vehicle body structure special, and since the wheels are special, the production cost of the wheels themselves is increased.
[0004]
The present invention solves the problems of the configuration of such a conventional traveling device, and provides a traveling assist device that can be applied to generally sold light vehicles such as wheelchairs and baby carriages. It is. Intended for normal driving such as paved roads, when a special road surface such as sandy ground, gravel road, snowy road, cobblestone road is encountered, inexpensive auxiliary equipment with a simple configuration is detachably attached. Thus, a travel assist device for a light vehicle capable of traveling on a special road surface is realized.
[0005]
[Means for Solving the Problems]
The present invention, in order to achieve the above object, is a travel assist device in which a wide outer ring member is easily and detachably attached along a wheel of a light vehicle such as a wheelchair. The outer ring is attached when traveling on special road surfaces such as gravel roads and sandy ground, and can be removed again during normal traveling. In this travel assist device, an outer ring member having a width larger than the width of the wheel of the light vehicle is attached to the outer periphery of the wheel to increase the contact area, so that the wheel can be prevented from being buried in sand or gravel. The outer ring member has a simple structure, is light in weight, and is not bulky, so that not only is it easy to carry, but also the production cost can be reduced. Also, due to its configuration, this travel assist device has a feature that the device can be attached and detached while a passenger or luggage is on the vehicle. Therefore, for example, when applied to a wheelchair, it is not necessary for the passenger to get off the wheelchair when attaching and detaching, and it is possible to provide a means that is not only for the physically handicapped and the elderly, but also for the assistant who assists in getting on and off. is there.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a case where the invention is applied to a wheelchair will be described in detail as an example of a preferred embodiment of a travel assist device for a light vehicle according to the present invention.
[0007]
FIG. 1 is a schematic view showing a state in which the travel assist device of the present invention is mounted on a rear wheel of a wheelchair. An outer ring member 3 is mounted on a rear wheel 2 of a wheelchair body 1. FIG. 2 is a side view. In a general light vehicle having four wheels, the driving assist device of the present invention is preferably mounted on all four wheels. However, in a wheelchair, most of the load is applied to the rear wheels. It is also effective to attach it to a wheel.
[0008]
FIG. 3 shows an embodiment of the travel assist device of the present invention. The travel assist device of the present invention is constituted by connecting two semicircular outer ring members 3 in an arc shape. . 3c shows an example of a connector for connecting two outer ring members, but any means may be used as long as it connects a plurality of members.
[0009]
FIG. 4 is a cross-sectional view showing a state where the outer wheel member 3 is mounted on the rear wheel 2 of the wheelchair, and shows an example in which the outer wheel member 3 is mounted on a rear wheel provided with a manual operation ring 4 for driving by the occupant himself. The covering portion 3a for covering the rear wheel 2 is formed in accordance with the shape of the manual operation ring 4, and firmly fixes the outer ring member to the wheel to prevent the outer ring member from coming off the wheel. In the present embodiment, the covering portion 3a completely covers the tire portion of the rear wheel. However, the outer ring member is attached to the manual operation ring 4 so that the contact surface of the outer ring member is flush with the contact surface of the tire. It may be attached. Of course, in a type of wheelchair having no ring for manual operation, it is necessary to form the covering portion 3a according to the shape of the wheel. Further, a grounding portion (surface) 3b is formed outside the covering portion 3a, but since this is a portion directly in contact with the road surface, it is preferable that the grounding portion (surface) be flat along the road surface, and it is also desirable to have some strength. Good. FIG. 4 shows an example in which rubber 3d for cushioning is attached to the ground contact surface 3b of the outer ring member 3 in order to improve riding comfort when traveling on a gravel road or a cobblestone road.
[0010]
The actual mounting procedure of the travel assist device in this embodiment is as follows. First, after temporarily attaching one of the semicircular outer ring members 3 to the rear wheel 2, the wheelchair is advanced by a half turn of the rear wheel, and the remaining outer ring members 3 are temporarily attached. The outer ring member is connected. If this operation is performed by a caregiver, the occupant does not need to bother to get out of the wheelchair and can wear the travel assist device. The same applies when the travel assist device is removed.
[0011]
FIG. 5 is a schematic view of a belt-shaped and flexible outer ring member, showing another embodiment of the travel assist device of the present invention. As the material, for example, rubber, plastic, or the like can be considered. In this case, a covering portion 3a is formed so as to surround the wheel 2, and a planar grounding portion (surface) 3b is formed outside the covering portion 3a. The covering portion 3a is provided with a corresponding notch 3e at an appropriate pitch because it is wound around the wheel 2. The actual mounting procedure in this embodiment is as follows. First, the belt-shaped outer ring member 3 is placed on the road surface in the traveling direction so that the ground contact portion 3b is located downward, and the wheelchair is advanced to place the rear wheel 2 on the outer ring member 3. Are overlapped, and both ends are aligned and connected so that the covering portion 3a is wound around the rear wheel so as to wrap the wheel 2. The point in which the rider does not need to step down from the wheelchair by performing the work and can mount the traveling assist device is the same as the above-described embodiment.
[0012]
Next, a method of using the travel assist device of the present invention in a wheelchair will be described. When the wheelchair encounters sand or a gravel road, the assistant attaches the traveling assist device of the present invention to the rear wheel of the wheelchair as described above. Thereafter, the caregiver pushes down the handle of the wheelchair slightly so that the front wheel floats, and moves the wheelchair forward with the front wheel floating so as to travel on sandy or gravel roads. The rear wheel has a large ground contact area due to the wide outer ring member, so that the rear wheel can travel without being taken by sand or gravel.
[0013]
In the above use, the wheelchair is supported only by the rear wheels, so it cannot be denied that the wheelchair is unstable. Accordingly, a description will be given below of a means for responding to a case where it is required to further stabilize a wheelchair, for example, when both the occupant and the caregiver are burdened due to a long length of sand or a gravel road.
[0014]
FIG. 6 is a schematic view of a state in which the front wheel 5 of the wheelchair is suspended on the bogie 6, and FIG. 7 is a side view thereof. In general, many wheelchairs sold in the market have a front wheel 4 in a caster structure in order to have a direction switching function, and in many cases, use small-diameter wheels. A truck 6 having a height enough to float is used. FIG. 8 schematically shows the bogie structure. Reference numeral 1 denotes a wheelchair main body, which allows the wheelchair main body 1 to be attached to the bogie 6. The wheels 7 of the truck 6 are wider than the front wheels 5 of the original wheelchair, so that the wheels are not buried in sand or gravel. In this embodiment, a rope 8 is tied to the carriage 6.
[0015]
A method of using the trolley 6 will be described. First, the travel assist device is mounted on the rear wheel 2 of the wheelchair as described above, and then the front wheel portion 5 is lifted and suspended on the bogie 6. Traveling forward is performed by the assistant pushing forward from behind as usual, or by pulling the rope 8 tied to the carriage 6 from the front of the wheelchair. Since the wheelchair is supported by four wheels, the wheelchair does not become unstable, and since the wheels 7 of the truck are wide, the wheels can travel without being buried in sandy ground, gravel roads, snowy roads and the like.
[0016]
As described above, the embodiment using the bogie has been described as a means for stabilizing the front wheel portion of the wheelchair. However, as another embodiment, a "sleigh" can be used instead of the bogie. Since the load on the front wheels is small, the coefficient of friction with the road surface does not increase, and the vehicle can run not only on snowy roads but also on sandy ground. Further, like a rear car or an old rickshaw, it is conceivable to run the vehicle with the front wheel portion lifted off the ground by detachably attaching a “traction handle” capable of towing the vehicle from the front of the wheelchair to the wheelchair body.
[0017]
【The invention's effect】
The travel assist device for a light vehicle according to the present invention has the following effects from the configuration described above.
[0018]
In the device of the present invention, it is possible to secure a wide contact area with the road surface by the outer ring member. Therefore, there was a problem that small-sized wheels of light vehicles such as wheelchairs and baby carriages were difficult to run because they were buried in sandy ground, gravel roads, snowy roads and cobblestone roads, or fitted in grooves. Therefore, the light vehicle can easily travel on such a special road surface.
[0019]
The device according to the present invention does not require any structural change on the side of the light vehicle and solves the problem only on the side of the travel assist device. Therefore, for example, by configuring the outer ring member so as to be compatible with a general wheelchair produced based on the JIS standard, it can be provided as a versatile means applicable to any wheelchair.
[0020]
Since the outer ring member constituting the device of the present invention has a simple configuration, the production cost can be reduced. If the outer ring member is configured to be compatible with a wheelchair based on the JIS standard, mass production becomes possible. Therefore, it can be widely used without imposing a large financial burden on the physically handicapped and the elderly.
[0021]
In the device of the present invention, the outer ring member constituting the device has a simple structure, is light, and is not bulky, so that it is easy to carry. In addition, the traveling assist device can be easily mounted while the vehicle is in the normal traveling state. Therefore, for example, in a wheelchair, the device can be easily attached to and detached from the wheelchair when needed by an assistant, and this can contribute to eliminating one of the barriers that may cause problems when going out with the wheelchair.
[0022]
Due to its configuration, this travel assist device is characterized in that the device can be attached or detached while a person with a physical disability, an elderly person, or luggage is carried on a vehicle. In the case of a wheelchair, there is no need for the passenger to get off the wheelchair when detaching. It provides a means that is friendly to the physically handicapped and the elderly, as well as to caregivers who have had to help getting on and off.
[0023]
In recent years, people with physical disabilities have become more outdoor-oriented. Until now, there were very difficulties in both the assistance equipment and the assistance system for going to the coast, but the wheelchair driving assistance device according to the present invention does not place a special burden on the assistance person, It made it possible to get into the sandy beach on the coast while in a wheelchair. It is no exaggeration to say that the driving assistance device of the present invention opens one bright page for people with physical disabilities.
[0024]
Although the above-described effects exist only by attaching the travel assist device to the rear wheel of the wheelchair, the vehicle during traveling can be stabilized by suspending the front wheel portion of the wheelchair on the bogie. Therefore, with the assistance of a caregiver, it can be adapted to leisure activities on the beach, such as the beach, and can be effectively used for outdoor activities by people with physical disabilities.
