20090127890SLIDING ROOF - The present invention provides a sliding roof for a vehicle including a plurality of roof panels separately mounted on an opening of a fixed roof of the vehicle in a longitudinal direction of the vehicle, a guide frame attached at a lower portion of each side edge of the opening, and an anchor installed into the guide frame to engage with at least part of the roof panel, so as to assist open-close operations of the plurality of the roof panels in the vicinity of a closed state thereof. Sliding of sliders attached to the each guide frame allows the plurality of the roof panels to open or close in the longitudinal direction of a vehicle. The sliding roof for a vehicle further includes a guide member installed into the guide frame to guide a movement of engagement portions of the plurality of the roof panels adjacent in the longitudinal direction of the vehicle. The anchor and the guide member are installed into an identical groove formed on the guide frame.05-21-2009
20100019545DEFLECTOR OF SLIDING ROOF - The present invention provides a deflector including a blade along a front edge of an opening of a fixed roof, movable upward and downward when the opening is opened and closed; a deflector arm whose one end is coupled to a frame on a vehicle body and whose other end is rotatably coupled to the blade via a first coupling shaft; a link arm whose one end is coupled to the frame on the vehicle body and whose other end is rotatably coupled to the blade via a second coupling shaft; and urging means for permanently urging a force to displace the blade upward. A cam member including first and second cam slots is provided on the frame on the vehicle body, a middle portion of the link arm is slidably engaged via a first pin with the first cam slot and one end of the link arm is slidably engaged via a second pin with the second cam slot, and the blade is housed in a laid down state with its upper portion displaced backward, and gradually stands up as displaced upward from a position where the blade is housed.01-28-2010
20100096889Sunroof Apparatus - A sunroof apparatus for opening or closing an opening formed on a fixed roof of an automobile includes: a movable front panel and a movable rear panel both provided in the fixed roof; a panel frame made of engineering plastic and attached around one of the panels; a hollow elastic weatherstrip attached around the panel frame attached around the one of the panels; a panel frame made of the engineering plastic and attached on a periphery end section of other one of the panels, the other one of the panels having a butt end section and the periphery end section; and a hollow elastic weatherstrip attached to the panel frame attached to the other one of the panels, wherein the opening is closed when the weatherstrip of the one of the panels and the butt end section of the other one of the panels butt against each other. This structure can enhance efficiency in molding weatherstrips since the weatherstrip attached around the two panels are in a hollow structure.04-22-2010
20100148540ROLL SUNSHADE DEVICE - A roll sunshade device, which includes a screen for shadowing an inner opening of a roof of a vehicle, a rotating body which is disposed ahead of the inner opening or behind the inner opening in a front-rear direction of the vehicle and rotates freely around an axis in a vehicle width direction, a turning member which is disposed at a predetermined distance from the rotating body in the front-rear direction of the vehicle and rotates freely around an axis in the vehicle width direction, and two circular wires which are disposed on both sides of the inner opening in the vehicle width direction, respectively and hung between the rotating body and the turning member, in which both edge portions of the screen in the vehicle width direction are supported by the two circular wires, respectively, and when the screen is slid in the front-rear direction of the vehicle from a state where the screen shadows the inner opening, the screen is folded along an outer circumferential surface of the turning member.06-17-2010

20090293470Over-Loading Prevention Device of Construction Machinery - In an over-loading prevention device including a hydraulic pump, a control valve, and a control lever, a discharge-quantity control unit performs constant-torque control which decreases a discharge quantity in proportion to an increase in a discharge pressure in the pump to control an input torque of the pump uniformly. An operation-state detection unit detects an actuation state of the control lever. A control unit outputs a control signal that sets the pump input torque to a minimum torque according to the constant-torque control, to the discharge-quantity control unit when the control lever is operated over a predetermined speed, and subsequently changes a level of the control signal to a maximum torque according to the constant-torque control in accordance with a predetermined control pattern to raise the pump input torque.12-03-2009

20090039682Sunroof apparatus for vehicle - A vehicular sunroof apparatus in which a sunroof panel for opening and closing an opening in a vehicle roof has a front panel and a rear panel. The sunroof apparatus also includes a rear panel drive mechanism for effecting rising/lowering and opening/closing movements of the rear panel relative to the opening. A restricting part provided in the rear panel drive mechanism restricts a front end part of the rear panel from rising when a rear end part of the fully closed rear panel is lowered.02-12-2009
20090072589Sunroof apparatus for vehicle - A vehicular sunroof apparatus includes a front panel, a rear panel, a linking rod, a rod-locking part, and a slider linking part. The linking rod is connected to a rear slider provided for opening the rear panel. The rod-locking part is disposed on a vehicle roof for locking a distal end of the linking rod when the rear panel is in a fully closed state. The slider linking part is provided on a front slider provided for opening/closing the front panel. The slider linking part is designed to engage with the distal end part and to release the distal end part from the locking engagement with the rod-locking part when the front slider moves from a fully closed position to a half-open position.03-19-2009
