ASCENDING/DESCENDING ASSISTING DEVICE FOR STAIR
PROBLEM TO BE SOLVED: To facilitate descending using a body weight of a user without the need of a power source, and not to increase burden even when obtaining a large assisting force in ascending.SOLUTION: An ascending/descending assisting device for stairs includes a slider part 36 along a stair body 3, an ascending/descending guidance part 30 for guiding ascending/descending of a balance weight 39, and an ascending/descending assisting device body 11 joined to the slider part 36. The body 11 includes a running board 13, a support post 12 as a grip part, and a grip part 14 for left hand, including a lever 22 for restraining/releasing upwardly moving. A wire rope 44 connected to the slider part 36 is connected to the balance weight 39 via a sheave 40 above the ascending/descending guidance part 30, and a coil spring 47 is interposed between the upper ends of the balance weight 39 and the ascending/descending guidance part 30. The balance weight 39 and the coil spring 47 are so formed that when the body 11 is upward movable, and an external force is not applied by a user, the body 11 moves upward, and when the user rides on in a state that the body 11 is near the uppermost stage, descending is started, and a descending speed is reduced close to zero near the bottom.SELECTED DRAWING: Figure 1
【課題】 動力源不要で、利用者の体重を利用して楽に下降でき、上昇時に大きな補助力を得られるようにしても負担が増大しない。【解決手段】 階段本体３沿いにスライダ部３６、釣り合い錘３９を昇降案内する昇降案内部３０を備え、スライダ部３６に昇降補助装置本体１１を結合する。本体１１は踏み板１３、掴み部としての支柱１２、上昇移動の拘束・解除をするレバー２２を備えた左手用掴み部１４を含む。スライダ部３６に連結したワイヤロープ４４を昇降案内部３０の上方のシーブ４０を介して釣り合い錘３９に連結し、釣り合い錘３９と昇降案内部３０の上端の間にコイルバネ４７を介装する。釣り合い錘３９とコイルバネ４７は、本体１１が上昇移動可能で、かつ利用者が外力を掛けていないとき本体１１が上昇し、本体１１が最上段近くにある状態で利用者が乗ったときは下降を開始し、最下段近くで下降速度を零近くに減速する構成とする。【選択図】 図１
