To provide a walk support device in which a user holds right-left handles for driving the device, in which the walk support device is stopped when the user releases the handle, and which can prevent or suppress travel in an unexpected direction even when the user accidentally pushes the held handle in an unexpected direction in a state where the user failed to apply a brake to the walk support device.SOLUTION: A walk support device includes a frame, a wheel including a drive wheel, driving means for travel, a handle, active force detecting means, progress speed detecting means, and a control unit. The control unit includes: a movement restriction control part which performs a movement restriction control that restricts drive of the driving wheel in the case where the active force detected at the handle continuously over a first predefined period time or more is at a predefined threshold value or less and the progress speed is at a predefined progress speed or less; and a progress control part which performs a progress control that releases the movement restriction control and drives the driving wheel in the case where the active force exceeding the active force threshold value is detected at the handle continuously over more than a second predefined period of time during the movement restriction control.SELECTED DRAWING: Figure 1
【課題】使用者が左右の持ち手を把持して駆動する歩行支援装置において、使用者が把持を止めた場合には歩行支援装置を停止させ、使用者が歩行支援装置にブレーキを掛けない状態で把持した持ち手を意図しない方向に偶発的に押した場合であっても、使用者の意図に反する方向への走行を防止、又は抑止することができる歩行支援装置を提供する。【解決手段】フレームと駆動輪を含む車輪と走行用駆動手段と持ち手と作用力検出手段と進行速度検出手段と制御装置を備え、制御装置は第1所定時間以上継続して持ち手で検出した作用力が所定閾値以下でかつ進行速度が所定進行速度以下の状態の場合は駆動輪の駆動を抑制する移動抑制制御を行う移動抑制制御部と、移動抑制制御中に第2所定時間を超えて継続して持ち手で作用力閾値を超える作用力を検出した場合には、移動抑制制御を解除し駆動輪を駆動する進行制御を行う進行制御部と、を有する歩行支援装置である。【選択図】図1
