Claim 16:
17. The lock with key having expanding arm elements according to claim 16
wherein the bevel gear structure comprises a first bevel gear, a second bevel gear, a third bevel gear, a first spherical bevel gear, and a second spherical bevel gear;
wherein the first bevel gear is a bevel gear;
wherein the first bevel gear forms a mechanical linkage between the third bevel gear and the first spherical bevel gear such that the rotation of the third bevel gear will rotate the first spherical bevel gear;
wherein the second bevel gear is a bevel gear;
wherein the second bevel gear forms a mechanical linkage between the third bevel gear and the second spherical bevel gear such that the rotation of the third bevel gear will rotate the second spherical bevel gear;
wherein the third bevel gear is a bevel gear;
wherein the third bevel gear attaches to a congruent end of the master shaft such that the rotation of the master shaft rotates the third bevel gear;
wherein the rotation of the third bevel gear rotates the first bevel gear;
wherein the rotation of the third bevel gear rotates the second bevel gear;
wherein the first spherical bevel gear is a spherically shaped bevel gear;
wherein the first spherical bevel gear forms a mechanical linkage between the first bevel gear and the first extension shaft such that the rotation of the first bevel gear will rotate the first extension shaft;
wherein the second spherical bevel gear is a spherically shaped bevel gear;
wherein the second spherical bevel gear forms a mechanical linkage between the second bevel gear and the second extension shaft such that the rotation of the second bevel gear will rotate the second extension shaft.
