Abstract
A panel assembly includes an outer member and an inner member, which overlap each other and jointly have an edge that includes a distal end portion of the outer member and a distal end portion projecting from an end of the inner member. The distal end portions are fastened together by sheet metal seaming. Boundary regions of the inner member between the distal end portion, which is seamed, and the end, which is not seamed, have respective clearances defined in the end, and which are spaced away from a seaming range in which the distal end portions are seamed.
Claims4
A panel assembly comprising:
- an outer member and an inner member, which overlap each other and jointly have an edge that includes a distal end portion of the outer member and a distal end portion projecting with a constant width from an end of the inner member extending substantially straight, the distal end portions being fastened together by sheet metal seaming,
- wherein boundary regions of the inner member between the distal end portion, which is seamed, and the end, which is not seamed, have respective clearances defined in the end of the inner member as cut-outs recessed in a forming direction, and which are spaced away from a seaming range in which the distal end portions are seamed.
A method of forming a panel assembly having an outer member and an inner member, which overlap each other and jointly have an edge that includes a distal end portion of the outer member and a distal end portion projecting with a constant width from an end of the inner member extending substantially straight, the distal end portions being fastened together by sheet metal seaming, the method comprising the steps of:
- forming, in boundary regions of the inner member between the distal end portion, which is seamed, and the end, which is not seamed, respective clearances defined in the end of the inner member as cut-outs recessed in a forming direction, and which are spaced away from a seaming range in which the distal end portions are seamed;
- placing the inner member and the outer member in overlapping relation to each other while the distal end portion of the inner member is spaced inwardly from the distal end portion of the outer member;
- and
- curling the distal end portion of the outer member and the distal end portion of the inner member, and fastening the distal end portion of the outer member and the distal end portion of the inner member together to form the edge by way of sheet metal seaming.
