Patent number: 6502896Abstract: A backhoe (1) includes an upper structure (3) supported by a traveling device (2) to be rotatable about a vertical swivel axis (X). The upper structure (3) carries an excavator (4) and a cab (12) and has a rear edge (3A) formed arcuate about the swivel axis (X) in plan view. The cab (12) defines an opening (31) with a door (32) attached through hinges (34). The door (32) is pivotable about a vertical open/close axis (Y) of hinges (34). The hinges (34) are arranged on a rear edge opening (31). Each hinge (34) includes a pair of hinges (34A and 34B) which are bent to place the axis (Y) forwardly of the rear end of door (32). Consequently, when the door (32) is set to a fully open position, the free end of door (32) is displaced to a position forwardly of the rear edge (3A) of upper structure (3).Type: GrantFiled: September 1, 2000Date of Patent: January 7, 2003Assignee: Kubota CorporationInventors: Yasuo Nakata, Yoshitaka Matsubara, Kenji Ikeda, Kenzo Koga, Teruo Kunizawa, Tomoaki Miyake
