Title:
HUMAN-OPERATED DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/162307
Kind Code:
A1
Abstract:
As regards conventional human-operated devices, it is not the case that actual human-powered movements are sufficiently utilized and converted into effective driving forces. This is because the movement input method is based on crank pedal rotational movements, in disregard of natural movements of human body leg sections. Disclosed is a human-operated device configured in such a way as to be provided with a crank member (9) which is interlocked with a drive shaft (7) that is pivotally supported by a frame (1), said frame (1) being a component of a vehicle body or a machine structure (the inter-shaft distance between the drive shaft (7) and a crank member movable support shaft (16) is denoted by r); a swing member (10) one end of which is pivotally supported by the frame (1) via a swing member fixed support shaft (14) (the inter-shaft distance between the swing member fixed support shaft (14) and a swing member movable support shaft (15) is denoted by x); a connecting member (11) at one end of which there is provided a pedal (13) that is pivotally supported by a pedal support shaft (12), the other end of which is pivotally supported by one end of the crank member (9) via the crank member movable support shaft (16), and a portion between both ends of which is pivotally supported by the other end of the swing member (10) via the swing member movable support shaft (15) (the inter-shaft distance between the crank member movable support shaft (16) and the swing member movable support shaft (15) is denoted by y); and a fixed section consisting of that portion of the frame which is between the swing member fixed support shaft (14) and the drive shaft (7) (the inter-shaft distance between the swing member fixed support shaft (14) and the drive shaft (7) is denoted by w). The human-operated device is characterized in that there is configured a lever-crank mechanism wherein the following conditions are met: (r + x) < (y + w), (r + y) < (x + w), and (r + w) < (x + y). By means of this device, human power is effectively converted into driving force, resulting in driving efficiency being significantly improved.
