Patent number: 7367611Abstract: An upper end of a link is attached to a roller shaft of an upper guide roller provided in an upper part of a front window for opening and closing a front opening of a cabin. A lower end of the link is provided with a wire retaining pin that moves in a wire guide rail. One end of an assist wire connected to a spring at the other end is connected to the wire retaining pin. Thus, in a window-closed state, tension acts on the front window as a pressing force for pressing the front window forward, and when the front window is to be opened, the tension acts through the link on the front window as an assisting force.Type: GrantFiled: September 29, 2006Date of Patent: May 6, 2008Assignee: Kobelco Construction Machinery Co., Ltd.Inventors: Tokuo Fujii, Hideki Ookubo

Patent number: 6450278Abstract: A construction machine including a maneuvering seat on which an operator sits, a guard cover for supporting the maneuvering seat thereon, and a control box arranged on one side of the maneuvering seat. The control box having a control valve and an operating lever for operating the control valve. The control box turning about a turning fulcrum so as to facilitate getting on and off when an operator gets on and off from the maneuvering seat. The construction machine further including hydraulic hoses which hang from the control valve and are pulled out of the control box. The hydraulic hoses having bent portions externally of the control box, the bent portions being displaced when the control box turns to absorb the up and down movement of the hydraulic hoses. Accordingly, the up and down movement of the hydraulic hoses caused when the control box is forced up is absorbed by bent portions provided externally of the control box.Type: GrantFiled: August 2, 2000Date of Patent: September 17, 2002Assignee: Kobelco Construction Machinery Co., Ltd.Inventors: Tadashi Shirogami, Tomohiko Ochi, Tokuo Fujii
