6 Claims. 1
This invention relates generally to a method of locating and holding in place, one metal member in relation to a second metal member.
Specifically the invention relates to a method of locating and holding in place one metal member in relation to a second metal member so that both members will become for all intents and purposes a temporary unitary structure which may be handled or moved about for subsequent fabricating operations without danger of the members shifting their relative positions prior to permanently securing the two together.
The object of the invention is to provide a method of locating a reinforcing metal member whereby the reinforcing member is located and held in place in relation to the reinforced member for subsequent fabricating operations whereby the two members are held together until subsequently permanently secured together, a
the metal of the reinforcing member 3 be deformed so that the inner edges of the tabs and the inner edges of the apertures with which they register abut one another. It is feasible, however, to dispose the tabs in their respective apertures 2 so that they do not necessarily abut the ends of the apertures but are disposed fairly loosely therein. Likewise, the tabs are of a width just sufficient to permit the tabs to fit within the apertures.
After the fiat metal stock of the side bar has been pierced to provide the requisite number of apertures 2, and the metal stock of the reinforcing member has been provided with properly spaced and located tabs 4, the two members are placed in relationship to one another as shown in Fig. 2, in other words member 3 is placed on the member i with tabs 4 bearing against or adjacent 1e inner edge of apertures 2. They may then method in which an additional operation of be placed in a forming machine such as a press either welding or riveting becomes unnecessary having a. mandrel 5 and a die 6. As the mandrel to pin the members together, and a method is caused to descend the blanks I .and 3 are which is relatively inexpensive to practice. formed to the channel configuration shown in A preferred embodiment of the invention will Fig. 3. be described as it may be carried out in relation As the mandrel 5 descends progressively into to reinforcing a critical area of a side bar for a the die the outer member I will be made to travel passenger car or truck. a greater distance into the die cavity than mem- In the drawing: ber 2. This will cause the position of the tabs 4 Figure 1 is a perspective view of a portion of a to shift in the apertures 2 so that at the compleside bar for an automotive vehicle reinforced in w tion of the stroke of the mandrel the tabs 4 will accordance with method of the invention; have shifted from one edge of the apertures 2 to Fig. 2 is atransverse sectional view of the reinthe opposite edges of the apertures where they forcing member and the reinforced member prior will be held tightly thereagainst, thereby resultto performing one step of the method of the ing inaunitary structure in that neither member invention; and will be able to shift its position relative to the 3 is a transverse Sectional V o the other while being moved about for subsequent joined members after completion of the method. fabricating operation In accordance with the invention side bar I is h above described invention provide 1 p ovidcd wit a plurality of Spaced elongated tively quick and inexpensive method for posip s 2 Which y be made, for example, as tively locating and holding reinforcing members y p c a flat metal blank O a W h Su l adjacent members that are to be reinforced so 130 be formed 111130 a side ball.

In the event that the stock of the metal member with respect to a second metal reinforcing member 3 is sufliciently light the promember which comprises providing one member jections may be formed by extrusion. with a plurality of spaced elongated apertures,
labs 4 are spaced according to the spacing of providing the second member with a plurality of apertures 2 so that they may register with the depending tab members formed from said second latter. In forming the tabs it is preferable that member and spaced to conform with said apertures, said tab members having a lesser longitudinal dimension than said elongated apertures, disposing one member in relation to the second member so that the inner edges of said tabs abut the inner edges of the apertures, and deforming said members causing a shifting of said tabs in said apertures so that the opposite edges of the tabs and the apertures abut one another.
2. The method of positioning and holding one metal member with respect to a second metal member which comprises providing one member with a plurality of spaced elongated apertures, providing the second member with a plurality of depending tab members formed from said second member and spaced to conform With said apertures, said tab members having one lesser dimension than said elongated apertures, disposing said tabs in said apertures so that the inner edges of the tabs and the apertures abut one another, and deforming said members to cause a shifting of said tabs in said apertures so that the outer edges of the tabs and the apertures abut.
3. The method of positioning and holding one metal member with respect to a second metal member for subsequent fabrication operations which comprises providing a plurality of spaced elongated apertures in one member, deforming the second member to provide a plurality of tabs projecting from one surface of said member and spaced to conform with the apertures of the other member, said tabs having lesser longitudinal breadth than said apertures, disposing the tabs in said apertures so that the inner edges of the tabs and apertures abut, and die forming said members simultaneously in a manner to cause greater deformation of one member than the other member to thereby permit said tabs to shift longitudinally of said apertures to a position opposite their initial disposition to cause said members to interlock.
