Description

高齢者向けの歩行器に関する技術 Technology on walker for elderly people

従来の歩行器では、車輪の直径が路面の段差を乗り越えるに不十分な場合に利用者に不要な労力を強いることがあり、特に高めの凸段差を越える際には歩行器が歩行の障害になることがある。また一般的なキャリーバッグは、車輪の四輪全てが独立して走行方向が旋回する自在型のキャスターを採用しているために直進性が損なわれ、高齢者がキャリーハンドルで体を支えて歩行器として代用するには転倒の可能性があって危険である。 In the conventional walker, when the diameter of the wheel is insufficient to get over the level difference on the road surface, the user may be forced to carry out unnecessary labor, especially when the height exceeds the high level difference. Can be Moreover, since a general carry bag adopts a free caster in which all the four wheels independently rotate in the traveling direction, the straightness is impaired, and the elderly support the body with a carry handle to walk. There is a possibility of falling and it is dangerous to substitute it as a container.

高齢者が買い物などの所用で外出する際の安全な歩行を支援する歩行器の機能を備えたキャリーバッグを開発する。 Develop a carry bag with the function of a walker to support safe walking when elderly people go out for shopping.

車輪の直径を、視覚障碍者誘導ブロックや石畳の目地、踏切などの一般的な路面の段差を容易に越えられるに十分な大きさとし、後輪の回転を伝達してフライホイールを回転させ、その惰力にて段差を乗り越えやすくすると共に、フライホイールのジャイロ効果によって直進性と直立性を良くした歩行器としての機能を備えたキャリーバッグを提供する。 Make the diameter of the wheel large enough to easily pass over the level difference of the road surface such as visually impaired person guidance block, cobblestone joint, crossing or the like, and transmit the rotation of the rear wheel to rotate the flywheel, The present invention provides a carry bag having a function as a walker, which makes it easy to climb over a step by a repulsion force, and which improves the rectilinearity and the uprightness by the gyro effect of a flywheel.

本発明は、特に高齢者を対象にした歩行器とキャリーバッグの機能を兼ね備えたもので、買い物などの所用で外出する際の歩行と荷物運搬を支援し、片手が自由に使えるので、エスカレーターなどを利用する際には手すりを掴んで体を支えることができる。 The present invention combines the functions of a walker and a carry bag for elderly people in particular, and supports walking and luggage transport when going out for shopping etc., and one hand can be freely used, so an escalator etc. You can hold the handrail to support your body when using the.

本発明は、通常の歩行時にフライホイールに回転エネルギーを蓄積しておき、そのエネルギーによる惰力にて一般的な路面の段差を越えやすくし、且つフライホイールのジャイロ効果によって直立安定性と直進安定性が改善された歩行器の機能を備えたキャリーバッグである。 The present invention stores rotational energy in the flywheel during normal walking, makes it easy to overcome a general road surface step by the repulsion by the energy, and stands upright stability and straight running stability by the gyro effect of the flywheel. It is a carry bag with the function of a walker with improved sex.

図1に全体図を示す。前輪111は走行方向が旋回可能な自在型のキャスターで利用者の歩行方向に自在に指向し、後輪101は左右の車輪が一本の後輪軸108によって連結されて第一のプーリー102が備えられており、ベルト103を介して後輪101の回転が第二のプーリー104に伝達されてフライホイール105を回転させる。 An overall view is shown in FIG. The front wheel 111 is a freely movable caster whose traveling direction can be turned freely, and the rear wheel 101 is provided with a first pulley 102 in which left and right wheels are connected by a single rear wheel shaft 108. The rotation of the rear wheel 101 is transmitted to the second pulley 104 via the belt 103 to rotate the flywheel 105.

第一のプーリー102と第二のプーリー104はメーカー側で三種類の直径が準備されていて互換性があり、換装可能な構造であって、利用者の希望に応じて直径比が1:1、1:1.5、1.5:1の三種類の組み合わせが選択でき、後輪101の回転に対するフライホイール105の回転数を選択してキャリーバッグの直立安定性と直進安定性及び歩行支援の感触が選択できる。 The first pulley 102 and the second pulley 104 are provided with three different diameters prepared by the manufacturer and are compatible and replaceable, and the diameter ratio is 1: 1 according to the user's request. , 1: 1.5, 1.5: 1 can be selected, and the rotation speed of the flywheel 105 with respect to the rotation of the rear wheel 101 is selected to support the upright and straight stability and the walking support of the carry bag. You can choose the feeling of

116はフライホイール廻りを覆うフライホイールカバーであり、110は後輪の軸受けやプーリー、ベルトを覆う後部カバーで、共に利用者の衣服が巻き込まれないように配慮したものである。荷物の収納に利用するバッグ114には軟質のプラスチック素材が使われ、キャリーハンドル117は利用者の体型に応じて高さが自由に調節できる。 A flywheel cover 116 covers the periphery of the flywheel, and 110 is a rear cover that covers the bearings, pulleys, and belts of the rear wheel so that the user's clothes can not be caught. A soft plastic material is used for the bag 114 used to store luggage, and the carry handle 117 can be freely adjusted in height according to the user's body shape.

ブレーキレバー120は、利用者がハンドルグリップ118を握る際に押し込まれ、ブレーキワイヤー119を介してフライホイール105を押さえていたブレーキシュー106が離れて後輪の制動が解除される。利用者が歩行停止する際にはハンドルグリップ118の握りを移動することでブレーキレバー120が復帰して後輪101を制動する。電車駅のプラットフォームなど傾斜のある歩行面に放置されたキャリーバッグが移動する虞がある場合には、このブレーキが効果的である。 The brake lever 120 is pushed when the user grips the handle grip 118, and the brake shoe 106 holding the flywheel 105 via the brake wire 119 is released to release the braking of the rear wheel. When the user stops walking, the grip of the handle grip 118 is moved to return the brake lever 120 to brake the rear wheel 101. This brake is effective when there is a risk that a carry bag left on a sloping walking surface such as a platform of a train station may move.

ブレーキワイヤーガイド121は、キャリーハンドル117を伸縮した際にブレーキワイヤー119がブレーキスプリング107やブレーキシュー106、フライホイール105に絡むのを防ぐ仕切り版である。 The brake wire guide 121 is a partition plate that prevents the brake wire 119 from being caught in the brake spring 107, the brake shoe 106, and the flywheel 105 when the carry handle 117 is expanded and contracted.

図2にブレーキ操作を示す。図2−1は停止時の状態で、ブレーキレバー202が操作されていないので、ブレーキシュー205はブレーキスプリング204によってフライホイール206に押し付けられて後輪を制動している。図2−2は歩行時の状態で、ブレーキレバー202が操作されてブレーキシュー205はフライホイール206から離され、後輪の制動が解除されている。 Fig. 2 shows the brake operation. As shown in FIG. 2-1 in the stopped state, since the brake lever 202 is not operated, the brake shoe 205 is pressed against the flywheel 206 by the brake spring 204 to brake the rear wheel. In the state of FIG. 2-2 in the state of walking, the brake lever 202 is operated, the brake shoe 205 is released from the flywheel 206, and the braking of the rear wheel is released.

図2−3にブレーキ操作の詳細を示す。ブレーキロッドA・208は、梃の原理の応用により高齢の利用者の弱い握力でブレーキレバー202を容易に操作するためのものである。ブレーキレバー202が押し込まれるとブレーキワイヤー203内部のインナーワイヤー210が引かれてブレーキロッドA・208が右回転し、ブレーキロッドB・209が左側に移動して、ブレーキスプリング204にてフライホイール206に押し付けられて後輪を制動していたブレーキシュー205がフライホイール206から離れて制動が解除される。 Details of the brake operation are shown in Fig. 2-3. The brake rod A 208 is for easily operating the brake lever 202 with weak grip of an elderly user by applying the principle of chewing. When the brake lever 202 is pushed in, the inner wire 210 in the brake wire 203 is pulled to rotate the brake rod A 208 rightward, the brake rod B 209 moves to the left, and the brake spring 204 moves to the flywheel 206 The brake shoe 205 which has been pressed to brake the rear wheel separates from the flywheel 206 and the braking is released.

図3−1にフライホイールの詳細を示す。肉抜き孔303で軽量化を図り、外周部分302を肉厚にして慣性モーメントが大きくなるように考慮した形状であって、材質には原則として鉄を使用するが、この限りではない。 Fig. 3-1 shows the details of the flywheel. Although the weight is reduced by the lightening holes 303 and the outer peripheral portion 302 is thickened to increase the moment of inertia, iron is used as the material in principle, but the present invention is not limited to this.

図3−2は、キャリーバッグの車輪が路面の一般的な段差を越える様子を示したものである。一般的なキャリーバッグの車輪306は直径の小さいものが多く、特に凸段差が越えにくいが、本発明の比較的に大きな直径の車輪305は前述のフライホイールとの相乗効果によって容易に段差を越えることができる。 FIG. 3B shows how the wheels of the carry bag cross a general level difference on the road surface. Many wheels 306 of a general carry bag have a small diameter, and in particular, it is difficult to overcome a convex step, but the relatively large diameter wheel 305 of the present invention easily crosses the step due to the above-mentioned synergistic effect with the flywheel. be able to.

図4に使用例を示す。キャリーハンドルは利用者の体型に応じて高さが調節できるので、体が支えやすくてブレーキレバーが操作しやすい位置を選ぶとよい。 An example of use is shown in FIG. Since the height of the carry handle can be adjusted according to the user's body shape, it is preferable to select a position where the body is easy to support and the brake lever is easy to operate.

前述の「発明を実施するための形態」にも詳述した通り、高齢者の歩行を支援するために直進性と直立性が良く、且つ路面の段差を越えやすい歩行器としての機能を備えたキャリーバッグとして実施される。 As described in detail in the above-mentioned "Form for carrying out the invention", in order to support elderly people's walking, it has good straightness and uprightness, and has a function as a walker that easily crosses over the level difference of the road surface. It is implemented as a carry bag.

高齢者の生活支援の環境整備が十分でない現状を背景に、各種の支援商品が開発されている。本発明はその一つであり、今後拡大が予想される同市場を指向した商品化が期待される。 A variety of support products have been developed against the background of the current situation where the environment maintenance of the life support for the elderly is not sufficient. The present invention is one of them, and commercialization aimed at the same market expected to be expanded in the future is expected.
