Abstract
A shoulder joint is provided. The shoulder joint includes a main support; a fold-out arm including an upper arm and a lower arm, the upper arm operable to pivot about a pin and the lower arm operable to pivot on a spindle on one end of the upper arm; and a first wheel attached to the pin, and a second wheel attached to the spindle. The upper arm and the lower arm are mechanically linked via the two wheels in such a way that rotation of the upper arm about the pin cause rotation of the second wheel and the lower arm relative to the upper arm, resulting in a bending or straightening of the arm.
Claims21
A fold-out shoulder joint comprising:
- a main support;
- a fold-out arm including an upper arm and a lower arm, the upper arm operable to pivot about a pin and the lower arm operable to pivot on a spindle on one end of the upper arm;
- a first wheel attached to the pin;
- a second wheel attached to the spindle;
- a first carriage and a second carriage arranged on the main support;
- and
- a first coupling for coupling the first carriage and the second carriage,
- wherein the upper arm is fastened to the second carriage by the pin, and the first carriage is connected to the upper arm such that the fold-out arm is folded out by pivoting about the pin when the first carriage and the second carriage are moved towards each other,
- wherein the first coupling is operable to couple the first carriage and the second carriage when the fold-out arm has been folded out, and the first carriage and the second carriage are operable to move in common in at least one direction, and
- wherein the upper arm and the lower arm are mechanically linked via the first wheel and the second wheel in such a way that rotation of the upper arm about the pin causes rotation of the second wheel and the lower arm relative to the upper arm, resulting in a bending or straightening of the fold-out arm.

An X-ray machine comprising:
- an x-ray device;
- and
- a shoulder joint comprising:
- a main support;
- a fold-out arm including an upper arm and a lower arm, the upper arm operable to pivot about a pin and the lower arm operable to pivot on a spindle on one end of the upper arm;
