20150299817 | METHOD FOR STRENGTHENING STEEL PLATE MEMBER - Provided is a method for strengthening a steel plate member employing a heating and quenching treatment. The method includes a first heating step, a partial cooling step, a second heating step and an entire cooling step, each step conducted in the written order. | 10-22-2015 |
20140070552 | Bumper - A bumper for vehicles having a high productivity and a large energy absorption amount in which the reinforcement beam is prevented from buckling. The bumper includes a reinforcement beam made of steel and support members protruding from a vehicle frame and supporting the reinforcement beam therebetween. The reinforcement beam is provided with a quenched portion provided at least over a portion where an obstacle hits the reinforcement beam. The reinforcement beam is further provided with unquenched portions next to the portion where the obstacle hits the reinforcement beam to sandwich the quenched portion. A mechanical strength of the unquenched portions is smaller than the mechanical strength of the quenched portion. | 03-13-2014 |
20140062105 | Bumper - Providing a bumper absorbing large amount of impact energy with respect to both a light collision and a heavy collision, and preventing the reinforcement beam from bending and protruding backward at a portion where an obstacle collides and from displacing backward in this protruding state. Provided is a bumper for vehicles including a reinforcement beam made of metal and a pair of support members having a hollow cross section, protruding from a vehicle frame, and supporting the reinforcement beam therebetween. A quenched region is provide over a portion including a middle of the reinforcement beam. Unquenched portions are provided on the pair of connecting portions or a pair of adjacent portions inside the pair of connecting portions. | 03-06-2014 |
20130168392 | Fuel Filler Port - Present invention provides a fuel filler port preventing a flowing back fuel from overflowing from the fuel filler port. The fuel filler port includes a first member and a second member. The first member and the second member are provided from upward to downward direction in written order. The second member is provided with a plurality of guiding projections and a fuel outlet provided between the adjacent projections. Since an inner diameter of the first opining is equal to an outer diameter of the fuel filler nozzle inserted, the flowing back fuel hardly flows through a gap between the first opening and the fuel filler nozzle. The flowing back fuel is discharged to the outside of a fuel filler pipe via the fuel outlet. | 07-04-2013 |
20120205361 | Method of Heating Plated Steel Plate - When applying a current to a plated steel plate, plating often biases. In the present invention, when applying a current, the current is applied with a flux guiding member arranged in proximity to a side surface of the plated steel plate. The direction of the magnetic flux at the side surface of the plated steel plate is corrected, and the bias of the plating is efficiently suppressed. | 08-16-2012 |
20120103944 | Manufacturing Method of Fuel Filler Tube - An annular surface of a retainer made of stainless steel plate and an annular surface of an inlet pipe made of zinc plated steel plate are surface contacted. Seam welding is then applied within a surface contacting region of the retainer and the inlet pipe to form a gap at both ends of the surface contacting region, and a zinc plated layer of the inlet pipe is melted to extrude zinc to the gap thus filling the gap with the zinc. According to such manufacturing method, a fuel filler tube excelling in rust preventing performance can be provided without performing a separate rust preventing countermeasure. | 05-03-2012 |
20110254316 | Steering Support Frame - The present invention provides a steering support frame composed of a deck cross member and fastening brackets attached to right and left ends of the deck cross member, and structured by fastening the fastening brackets to respective fitting parts provided in right and left vehicle body frames so as to bridge the deck cross member between the right and left vehicle body frames. To connect the deck cross member and the fastening brackets, one of the ends of the deck cross member is welded to both of a body plate and a surface contact plate of the fastening bracket on a driver seat side, and the other end of the deck cross member is welded only to a body plate of the fastening bracket on a passenger seat side, whereby the deck cross member has a strength difference between the driver seat and passenger seat sides. | 10-20-2011 |
20110253857 | Fastening Bracket of Deck Cross Member - The present invention provides a fastening bracket for fastening right and left ends of a deck cross member to respective fitting parts of a vehicle body frame. The fastening bracket includes a body plate to which one of the ends of the deck cross member is connected, a surface contact plate to which a fastening nut corresponding to a bolt to be inserted into corresponding one of the fitting parts of the vehicle body frame is fixed, the surface contact plate being provided in the body plate, a connection plate that is a part for connecting the body plate and the surface contact plate, the connection plate having a width in a direction perpendicular to a connecting direction of the body plate and the surface contact plate equal to or smaller than the surface contact plate, and a demarcating slit for demarcating the body plate and the surface contact plate. | 10-20-2011 |
20110127783 | Bumper Reinforcement Member - A bumper reinforcement member including a front reinforcement member and a back reinforcement member, wherein the front reinforcement member includes a front intermediate face, which becomes a bumper front face, and a front groove arranged above and below the front intermediate face and that recesses from the bumper front face side towards a bumper rear face side; the back reinforcement member includes a back intermediate face positioned on a front side than bottom faces of both upper and lower front grooves, and a back groove arranged above and below the back intermediate face and that recesses from the bumper front face side towards the bumper rear face side; and the front reinforcement member and the back reinforcement member have the front groove contained in the back groove without bringing at least the bottom faces of the front groove and the back groove into surface contact with each other. | 06-02-2011 |
