Abstract:
1. A mechanical module for a key comprising: a key body that includes a casing element; a key bit fitted to the key body such that the key bit can pivot about a rotation axis and relative to the casing element between a use position and a stowed away position; a control button configured to move parallel to the rotation axis between a normal position and a depressed position to allow the key bit to pivot about the rotation axis and relative to the casing element; and a pivoting support, holding the key bit and engaging with the control button; wherein the control button includes a first mechanical structure comprising at least four protrusions, and the casing element includes a second mechanical structure comprising at least four notches, wherein the first mechanical structure of the control button is configured to engage the second mechanical structure of the casing element by interlocking each of the at least four protrusions with a corresponding one of the at least four notches at least at four spaced-apart locations around the rotation axis for preventing rotation of the control button about the rotation axis relative to the casing element when the control button is in the normal position; wherein the second mechanical structure is integrated with the casing element and comprises the same material as the casing element; wherein the first and the second mechanical structures oppose a force tending to pivot the key bit with respect to the body of the key; and wherein the casing element remains stationary relative to the key body as the key bit moves between the use and the stowed away positions.
