An elastic prismatic key consists of two bars with rectangular cross section in the ends of which one or more round openings are provided, the ends of arc-like springs are placed to those. On the facets of the bars with rectangular cross section that form a long gap torus-like openings are provided, one in each, in such way that at assemblage of the key a toroid-shape cavity is formed, this is placed symmetrically with respect to the long gap, there an elastic element is placed, this is arranged as a torus with cross cut. The cross cut of the elastic element is not less than width of the long gap between the bars with rectangular cross section. |
