    摘要： A method of securing together, as by staking, superimposed strips or sheets of rigid yet deformable material, such as mild steel, having generally planar surfaces. The method includes positioning the superimposed sheets between a driven punch and the working face of a stationary anvil upon sheet-supporting members resiliently urged toward each other mounted laterally of said anvil and providing with said punch and anvil a forming space extending directly as well as laterally above, and laterally below, the anvil working face. By a single stroke of said punch, the punch causes a flow of the material of the strips into the forming space to form therein telescoped hollow bosses, or rivets, with a lower wall portion of the inner boss expanded laterally into interlocking engagement with the corresponding laterally confined wall portion of the outer boss and with the material of the lower transverse end of the outer boss yieldably restrained by said resiliently urged members to a predetermined degree of lateral expansion yet free to flow into the portion of the forming space laterally below said anvil working face to provide downwardly extending lateral flanges. The punch is preferably formed with a pair of opposed lower downwardly converging surfaces and with an intermediate pair of parallel surfaces which together define a generally rectangular striking end, the face of which is arcuate. With this configuration, the striking end of the punch forms hollow bosses that interlock in one plane including the common axis of the bosses, but that are noninterlocking in a plane normal to the first and also including the common axis.

    摘要： A section of a sectional overhead garage door comprises a ribbed, plastic panel surrounded by a frame including two horizontal rails interconnected by two end rails, each horizontal rail having two spaced-apart holding flanges extending the length thereof toward the other horizontal rail and receiving the adjacent panel margin therebetween, the outer holding flange having a gripping member thereon extending toward the inner holding flange, each end rail having a tongue at each end thereof disposed in use between the adjacent panel margin and the adjacent outer holding flange and provided with an outwardly extending gripping member thereon, the holding flange gripping members being pressed into and embedded in the end rail tongues and the panel margins, with the tongue gripping members being embedded in the outer holding flanges all for securely clamping the frame to the panel and the end rails to the horizontal rails.
