CEILING HATCH STRUCTURE OF WORKING CAR

摘要

PROBLEM TO BE SOLVED: To provide a ceiling hatch structure for opening/closing a hatch pivoted by a hinge at the cabin ceiling of a working car having an arm structure capable of improving controllability at the closing time of the hatch while sufficiently securing the upward visibility. SOLUTION: The ceiling hatch structure is adapted for a working car having an arm structure to open and close the hatch 2 pivoted to the ceiling 1a of the cabin 1 by the hinge 3. The hatch structure is provided with a slide structure constituted of a stay 5 and a groove 6 making the hatch 2 slidable rearward and a rotary structure constituted of the hinge 3 and the stay 5 rotating the hatch 2. The hatch 2 is turned upward by the rotary structure while sliding the hatch 2 rearward by the slide structure. COPYRIGHT: (C)2003,JPO
