INTERFERENCE ASSEMBLY, HINGE UTILIZING THE SAME, AND COLLAPSIBLE DEVICE UTILIZING THE HINGE

摘要

An interference assembly comprises a first element defining a first side and a through hole, and a second element rotatably relative to the first element, with defining a first surface facing and corresponding to the first side. Two staggered first raised portions along a circumference of the first element protrude from the first side. Two staggered second raised portions around the through hole protrude from the first side. The first raised portions communicate with the corresponding second raised portions. The second element defines a fixing hole, two first depressed portions staggered along a circumference in the first surface, and two second depressed portions staggered around the fixing hole in the first surface. The first depressed portions also communicate with the corresponding second depressed portions.
