Abstract:
1. A mobile power generator apparatus comprising: a frame having a power generator mounted therein; and a pulling unit provided on the frame and operable by a human operator to pull and move the mobile power generator apparatus, the pulling unit comprising: an upper pivoting link and a lower pivoting link disposed in vertically proximate relation to each other, the upper and lower pivoting links being pivotally connected at their respective one end portions to the frame to undergo pivotal movement in a vertical plane; a pulling handle having a grip section provided on a distal end portion thereof, the pulling handle being pivotally directly connected at a proximal end portion thereof to respective other end portions of the upper and lower pivoting links; and, a link cover having a substantially U-shaped cross section and having an interior space accommodating therein the upper and lower pivoting links, the link cover having a first end portion and a second end portion opposite to the first end portion, the first end portion of the link cover pivotally connected to the frame along with the one end portion of the upper pivoting link, the second end portion of the link cover fixed to the other end portion of the upper pivoting link, wherein the pulling handle expands in a direction where the grip section moves away from the respective one end portions of the upper and lower pivoting links, by pivoting about the proximal end portion in interlocked relation to upward pivotal movement, about the respective one end portions, of the upper and lower pivoting links responsive to a pulling force applied to the pulling handle by the human operator, and the pulling handle collapses in a direction where the grip section moves toward the respective one end portions of the upper and lower pivoting links toward a collapsed position, by pivoting about the proximal end portion in interlocked relation to downward pivotal movement, about the respective one end portions, of the upper and lower pivoting links responsive to a pushing force applied to the pulling handle by the human operator.
