Patent ID: 8695167

Claim:
A handle device of a work machine, comprising: a frame for carrying a work device, said frame comprising a cross-frame part; a transportation/movement handle attached in a foldable manner to the frame, having left and right grip parts at distal ends thereof, and having a U-shaped support part at a proximal end thereof, the U-shaped support part including a handle engaging/disengaging part; at least two handle turning mechanisms, each of which support one of left and right attachment parts of the handle, the left and right attachment parts of the handle intersecting the cross-frame part of the frame at a handle support part such that the handle can turn about the handle support part of the cross-frame part as a turning fulcrum; and a clamp mechanism for detachably fixing the handle engaging/disengaging part to the frame, wherein the handle engaging/disengaging part is spaced from the left and right attachment parts and is at a center of an end of said U-shaped support part, the U-shaped support part being opposite the left and right grip parts, wherein the handle engaging/disengaging part of the handle is disposed on an opposite side of the left and right attachment parts relative to the grip parts, in a proximal-distal direction of said handle, and wherein the clamp mechanism comprises: a clamp body for clamping the handle engaging/disengaging part by closing; a spring of the clamp body, for holding the clamp body in an open standby state; an actuating protuberance which, when closed against a spring force of the spring, extends from a turning member of the clamp body toward the handle engaging/disengaging part so as to contact and be pushed by the handle engaging/disengaging part; and a restraining mechanism for automatically restraining a distal end of the clamp body by a spring force when the clamp body is closed due to the actuating protuberance being pushed further and brought nearer to the frame.
