Mobile power generator apparatus includes: upper and lower pivoting links vertically pivotably connected at their one end portions to a frame; and a handle mounted to the frame for pulling the generator apparatus and connected at its proximal end portion to other end portions of the links. The handle is expandable, in a direction where a grip moves away from the links, in interlocked relation to upward pivotal movement of the links responsive to a pulling force, and is collapsable, in a direction where the grip moves toward the links, in interlocked relation to downward pivotal movement of the links responsive to a pushing force.

1. A mobile power generator apparatus comprising: a frame having a power generator mounted therein; anda 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, andthe 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. 2. The mobile power generator apparatus according to claim 1, wherein expanding and collapsing movement of the pulling handle is regulated by the upper and lower pivoting links in such a manner that the grip section moves in a predetermined trajectory during the expanding and collapsing movement. 3. The mobile power generator apparatus according to claim 1, wherein the upper and lower pivoting links have first and second engaging portions, respectively, and as the pulling handle is expanded so that the grip section is shifted away from the respective one end portions of the upper and lower pivoting links to a pulling position for the human operator to pull and move the mobile power generator apparatus with the grip section, the second engaging portion of the lower pivoting link abuts against the first engaging portion of the upper pivoting link to thereby prevent the pulling handle from being expanded beyond the pulling position. 4. The mobile power generator apparatus according to claim 1, which further comprises: a handle retaining mechanism including first and second engaging elements that engage with each other as the pulling handle is expanded, so that the pulling handle is prevented from collapsing, due to weights of the pulling handle and the upper and lower pivoting links, when the pulling handle is in an expanded position with the grip section located in a pulling position for the human operator to pull and move the mobile power generator apparatus with the grip section, whereinthe first engaging element comprises a retaining recess formed in the link cover, andthe second engaging element is a boss provided at the other end portion of the lower pivoting link. 5. The mobile power generator apparatus according to claim 3, wherein the second engaging portion of the lower pivoting link is a boss provided at the other end portion of the lower pivoting link, and the first engaging portion of the upper pivoting link is a region of the upper pivoting link located near the other end portion of the upper pivoting link. 6. The mobile power generator apparatus according to claim 3, further comprising: a handle retaining mechanism including first and second engaging elements that engage with each other as the pulling handle is expanded, so that the pulling handle is prevented from collapsing, due to weights of the pulling handle and the upper and lower pivoting links, when the pulling handle is in an expanded position with the grip section located in the pulling position for the human operator to pull and move the mobile power generator apparatus with the grip section, whereinthe first engaging element comprises a retaining recess formed in the link cover, andthe second engaging element is a boss provided at the other end portion of the lower pivoting link. 7. The mobile power generator apparatus according to claim 1, wherein the link cover has a handle holder for holding the pulling handle when the pulling handle is in a collapsed position where the grip section is located near the respective one end portions of the upper and lower pivoting links.
