  • Patent number: 8726514
    Abstract: An object of the present invention is to provide a panel manufacturing method capable of easily adapting to manufacture of panels, such as door panels, of different sizes. The present invention provides a panel manufacturing method for a panel made of an outer plate integrated with an inner plate. The method includes a step of applying an adhesive to a predetermined place on the outer plate; a step of mating the outer plate and the inner plate with each other and providing preliminary bonding by laser welding; a step of hemming by bending an outer edge portion of the pre-bonded outer plate to wrap over a circumferential edge portions of the inner plate and then pressing flat; and a step of sealing the panel, after the outer plate has undergone the hemming step on its circumferential edge portions, by applying an adhesive.

  • Patent number: 8413382
    Abstract: A second hinge plate supported pivotally on a first hinge plate using a shaft member so as to open and close. In the second hinge plate, a bracket is molded integrally at the upper edge of the end opposite the shaft member. A vertical shaft of a hold-stay rod is loosely fitted into a shaft hole of the bracket so as to move rotationally and slide in a vertical direction. A horizontal shaft of the hold-stay rod is inserted into a guide hole of a guide plate welded to the first hinge plate and slidable, and a stopper is folded and formed at the leading end of the hold-stay rod. The stopper is inserted into an engaging hole by movement from a guide to a receiving plate due to the opening movement of the second hinge plate and can be taken out from the engaging hole by a pushing-up operation.
