特開2005−80992号公報JP-A-2005-80992

この種の車椅子では、座席の後部に、介護者が車椅子を操舵するための操舵部を備えたものが殆どである。しかしながら、たとえば車椅子を使用する人が介護者を要せずに本人のみで使用する場合に限っては介護者用の操舵部は不要なものとなる。特に近年では介護という意識をあまり連想させないような様々なデザイン重視の車椅子が提案されており、介護者用の操舵部の設計処理は車椅子のデザインにおいて重要な要素となっている。   Most of these types of wheelchairs are provided with a steering section for a caregiver to steer the wheelchair at the rear of the seat. However, for example, only when the person using the wheelchair does not need a caregiver and uses it alone, the steering part for the caregiver becomes unnecessary. Particularly, in recent years, various design-oriented wheelchairs that are not associated with care consciousness have been proposed, and a design process of a steering unit for a caregiver is an important factor in wheelchair design.

本発明はこのような課題を解決するために創作されたものであり、車椅子において、介護者用の操舵部に関して構造の合理化を図ることを目的とする。   The present invention has been created to solve such problems, and an object of the present invention is to rationalize the structure of a steering unit for a caregiver in a wheelchair.

前記課題を解決するため、本発明は、座席の両側に肘掛け部を有する車椅子において、前記肘掛け部は、座席後方の車幅方向に沿う軸心回りに回動可能に取り付けられ、後方に回動したとき介護者による車椅子の操舵部として構成され、前記軸心回りに回動可能に取り付けられる背もたれ部を有し、この背もたれ部の両端に前記肘掛け部が一体に形成されていることを特徴とする。 In order to solve the above-mentioned problems, the present invention provides a wheelchair having armrests on both sides of a seat, wherein the armrests are attached so as to be rotatable about an axis along the vehicle width direction behind the seat and are rotated rearward. It is configured as a steering portion of a wheelchair by a caregiver, and has a backrest portion that is rotatably attached around the axis, and the armrest portions are integrally formed at both ends of the backrest portion. To do.

本発明によれば、肘掛け部は、着席した本人のみで車椅子を走行させる場合には肘掛けとして機能し、介護者が付き添う場合のみ介護者の操舵部として機能する。これにより、介護者用の操舵部に関して構造の合理化を図れる。   According to the present invention, the armrest portion functions as an armrest when the wheelchair is run only by the seated person, and functions as a steering portion of the caregiver only when the caregiver is accompanied. Thereby, rationalization of the structure regarding the steering part for caregivers can be achieved.

本発明によれば、肘掛け部の回動機構を部品点数の少ない簡単な構造で実現できる。   According to the present invention, the rotation mechanism of the armrest portion can be realized with a simple structure with a small number of parts.

本発明によれば、介護者用の操舵部に関して構造の合理化を図れ、車椅子のデザイン性も向上する。   According to the present invention, it is possible to rationalize the structure of the steering unit for a caregiver and to improve the design of the wheelchair.

図1および図2において、本発明に係る車椅子1は、下端に車輪が軸装されたフレーム2と、フレーム2の下部に設けられる足載せ部3と、フレーム2に設けられる座席部4と、を備えている。本実施形態の車椅子1は、自走式であり、また不使用時にはフレーム2をコンパクトに折り畳めるようになっている。   1 and 2, a wheelchair 1 according to the present invention includes a frame 2 with wheels mounted on the lower end, a footrest portion 3 provided at a lower portion of the frame 2, a seat portion 4 provided on the frame 2, It has. The wheelchair 1 of the present embodiment is self-propelled, and the frame 2 can be folded compactly when not in use.

フレーム2は、前輪5が軸着される前輪支持フレーム7と、左右一対の後輪6が軸着される後輪支持フレーム8と、を備えて構成されている。フレーム2は主にパイプ材、板材等から構成されるものであり、その材質は金属、合成樹脂等、特に限定されるものではない。   The frame 2 includes a front wheel support frame 7 on which a front wheel 5 is attached and a rear wheel support frame 8 on which a pair of left and right rear wheels 6 are attached. The frame 2 is mainly composed of a pipe material, a plate material, and the like, and the material is not particularly limited, such as a metal or a synthetic resin.

前輪支持フレーム7は、使用時状態において、上端側が後方に位置するように傾斜状に延設される緩円弧状の長尺部材からなる。前輪支持フレーム7の下端には従動輪として前輪5が軸着されている。また、前輪支持フレーム7の下部には足載せ部3が取り付けられている。後輪支持フレーム8は、図1(a)に示すように正面視して、下方に向けて二又状に形成されており、図1(c)に示すように使用時状態において、上端側が前方に位置するように傾斜状に配される。左右一対の後輪6はそれぞれ個別に駆動可能な駆動輪として機能し、インホイールモータ9を介して後輪支持フレーム8の下端に軸着されている。なお、インホイールモータ9の駆動源であるバッテリについては図示を省略している。   The front wheel support frame 7 is formed of a long member having a gentle arc shape extending in an inclined manner so that the upper end side is located rearward when in use. A front wheel 5 is attached to the lower end of the front wheel support frame 7 as a driven wheel. A footrest 3 is attached to the lower part of the front wheel support frame 7. The rear wheel support frame 8 is formed in a bifurcated shape when viewed from the front as shown in FIG. 1 (a), and the upper end side is in an in-use state as shown in FIG. 1 (c). It is arranged in an inclined shape so as to be located in the front. The pair of left and right rear wheels 6 function as drive wheels that can be individually driven, and are pivotally attached to the lower end of the rear wheel support frame 8 via an in-wheel motor 9. Note that illustration of a battery which is a drive source of the in-wheel motor 9 is omitted.

本実施形態では、座席部4の高さを2段階に調整できるようになっており、前輪支持フレーム7の長手方向中程と後輪支持フレーム8の上端近傍とが、車幅方向に沿う連結軸10により互いに回動可能に連結されている。そして、後輪支持フレーム8の上端と、前輪支持フレーム7における連結軸10よりも上方の部位とに掛け渡されるように座席部4が設けられている。座席部4は、その前端寄りが、後輪支持フレーム8に対し車幅方向に沿う取付軸12を介して回転可能に取り付けられるとともに、その後端寄りが、前輪支持フレーム7に形成された長孔13に対し車幅方向に沿う取付軸14を介してスライド可能に取り付けられている。   In the present embodiment, the height of the seat portion 4 can be adjusted in two stages, and the longitudinal middle of the front wheel support frame 7 and the vicinity of the upper end of the rear wheel support frame 8 are connected along the vehicle width direction. The shafts 10 are rotatably connected to each other. And the seat part 4 is provided so that it may span over the upper end of the rear-wheel support frame 8, and the site | part above the connection shaft 10 in the front-wheel support frame 7. FIG. The seat portion 4 is attached to the rear wheel support frame 8 so as to be rotatable with respect to the rear wheel support frame 8 via a mounting shaft 12 extending in the vehicle width direction, and the rear end is a long hole formed in the front wheel support frame 7. It is slidably attached to 13 through an attachment shaft 14 along the vehicle width direction.

以上により、図3(a)に示すように、前輪支持フレーム7と後輪支持フレーム8とが連結軸10回りに回動して前輪5,後輪6間のホイールベースが小さくなった状態では、取付軸14が長孔13の下端よりも若干上方に位置し、座席部4の位置が高くなる。そして、図3(b)に示すように、前輪支持フレーム7と後輪支持フレーム8とが連結軸10回りに回動して前輪5,後輪6間のホイールベースが大きくなった状態では、取付軸14が長孔13の下端に位置し、座席部4の位置が低くなる。これにより、使用者はゆったりと安定して座りたいときには車椅子1を図3(b)のように使用し、目線を高く確保したい場合には車椅子1を図3(a)のように使用するなどの使い分けができる。   3A, the front wheel support frame 7 and the rear wheel support frame 8 are rotated around the connecting shaft 10 so that the wheel base between the front wheel 5 and the rear wheel 6 is small. The mounting shaft 14 is positioned slightly above the lower end of the long hole 13, and the position of the seat portion 4 is increased. Then, as shown in FIG. 3B, in the state where the front wheel support frame 7 and the rear wheel support frame 8 rotate around the connecting shaft 10 and the wheel base between the front wheel 5 and the rear wheel 6 becomes large, The attachment shaft 14 is located at the lower end of the long hole 13 and the position of the seat portion 4 is lowered. Thereby, the user uses the wheelchair 1 as shown in FIG. 3B when he / she wants to sit comfortably and stably, and uses the wheelchair 1 as shown in FIG. Can be used properly.

前輪支持フレーム7の上端には、車幅方向に沿って背もたれ部15が設けられている。この背もたれ部15は、車幅方向に沿う軸心O回りに回動可能となるように前輪支持フレーム7の上端に取り付けられている。そして、背もたれ部15の両端に肘掛け部16が一体に形成されている。すなわち、肘掛け部16は、背もたれ部15と一体となって前記軸心O回りに回動するように構成されている。背もたれ部15および肘掛け部16はたとえば柔軟な表皮層を有した部材からなる。肘掛け部16の先端にはグリップ部17が形成されている。なお、グリップ部17周りには、インホイールモータ9を駆動制御するためのコントローラ(図示せず)が適宜に配される。   A backrest portion 15 is provided at the upper end of the front wheel support frame 7 along the vehicle width direction. The backrest portion 15 is attached to the upper end of the front wheel support frame 7 so as to be rotatable around an axis O along the vehicle width direction. And the armrest part 16 is integrally formed in the both ends of the backrest part 15. FIG. That is, the armrest portion 16 is configured to rotate about the axis O together with the backrest portion 15. The backrest 15 and the armrest 16 are made of a member having a flexible skin layer, for example. A grip portion 17 is formed at the tip of the armrest portion 16. A controller (not shown) for driving and controlling the in-wheel motor 9 is appropriately arranged around the grip portion 17.

肘掛け部16は、図4に示すように後方に回動したときには、介護者による車椅子1の操舵部18として機能する。この場合、車椅子1の走行は、インホイールモータ9を用いた自走モードではなく、基本的に介護者の手押しによる人力モードとなる。そのため、走行スピードも比較的低速となり、車椅子1に座っている人にとっては上半身が不安定になることもないため、肘掛け部16が存在しなくてもさほど問題とはならない。なお、肘掛け部16は、前方に回動して肘掛けとして使用される位置と、操舵部18として使用される位置とにおいて、それぞれ図示しないストッパにより回動規制されて位置決めされる。   The armrest portion 16 functions as the steering portion 18 of the wheelchair 1 by the caregiver when rotated backward as shown in FIG. In this case, traveling of the wheelchair 1 is not a self-propelled mode using the in-wheel motor 9 but basically a human-powered mode by the caregiver's hand. Therefore, the traveling speed is also relatively low, and the upper body of the person sitting on the wheelchair 1 does not become unstable. Therefore, even if the armrest portion 16 is not present, it does not matter much. In addition, the armrest part 16 is rotationally regulated by a stopper (not shown) and positioned at a position where the armrest part 16 is rotated forward and used as an armrest, and a position where it is used as the steering part 18.

不使用時には、図5に示すように、前輪支持フレーム7と後輪支持フレーム8とを連結軸10回りに回動させてコンパクトに折り畳むことができる。その際には肘掛け部16も前輪支持フレーム7と重なるように回動できるようになっている。   When not in use, as shown in FIG. 5, the front wheel support frame 7 and the rear wheel support frame 8 can be rotated around the connecting shaft 10 to be compactly folded. At that time, the armrest portion 16 can also be rotated so as to overlap the front wheel support frame 7.

本発明によれば、肘掛け部16は、介護者を要せずに着席した本人のみで車椅子を走行させる場合には肘掛けとして機能し、介護者が付き添う場合のみ介護者の操舵部18として機能する。これにより、介護者用の操舵部18に関して構造の合理化を図れる。また、本人のみで使用するときには介護者用の操舵部が見当たらない構造となるため、介護イメージのさほどない若々しいデザインを目指すうえで有利となる。   According to the present invention, the armrest portion 16 functions as an armrest when the wheelchair is run only by the person who is seated without requiring a caregiver, and functions as the steering portion 18 of the caregiver only when the caregiver is accompanied. . Thereby, rationalization of the structure regarding the steering unit 18 for the caregiver can be achieved. Moreover, since it becomes the structure where the steering part for caregivers is not found when it uses only by the person, it is advantageous when aiming at the youthful design which does not have a care image.

さらに、軸心O回りに回動可能に取り付けられる背もたれ部15を有し、この背もたれ部15の両端に肘掛け部16が一体に形成される構成とすれば、肘掛け部16の回動機構を部品点数の少ない簡単な構造で実現できる。   Furthermore, if it has the backrest part 15 attached to the periphery of the shaft center O so that rotation is possible, and it is set as the structure by which the armrest part 16 is integrally formed in the both ends of this backrest part 15, the rotation mechanism of the armrest part 16 will be components. This can be realized with a simple structure with a small number of points.

以上、本発明の好適な実施形態を説明した。説明した実施形態では自走式の車椅子としたが、本発明は非自走式の車椅子にも適用可能である。また、肘掛け部16は、背もたれ部15とは独立して設ける構造にしてもよい。   The preferred embodiment of the present invention has been described above. In the described embodiment, a self-propelled wheelchair is used, but the present invention can also be applied to a non-self-propelled wheelchair. Further, the armrest portion 16 may be structured to be provided independently of the backrest portion 15.
