ABSTRACT:
This invention relates to a parking grip chock made from sheet and to a process for the production of the same. The chock is substantially wedge-shaped and is characterized in that it is formed from a single piece blanked and bent provided with tongues folded at right angle and welded each other which define the supporting surface and the rear wall of the chock.
The process presents at least a blanking operation from a metal band of a flat blank having a predetermined shape, and a bending operation for subsequent operations on the blank in order that the same takes a wedge shape, bent edges of the blank being mutually welded.
