  • the above patents disclose a mechanism for supporting the optical loupes on a frame and also for enabling the loupes to be adjusted.
  • the object of the present invention is to provide further improvements in the mounting of head worn instruments such as the mounting of the loupe assembly on a frame of the optical loupes.
  • a first aspect of the invention provides head worn instrument including: an instrument; a mounting element coupled to the instrument, the mounting element including one of a socket and a ball element; a frame having a mounting section for receiving the mounting element, the mounting element including the other of the socket and the ball element; and biasing means for biasing the ball element and socket together to form a releasable joint of the instrument to the frame, and thereby allow the instrument to be disconnected from the frame so that different instruments can be selectively coupled to the frame.
  • the instruments may include optical loupes, light sources and other instruments which a surgeon or other person needs to wear in order to perform a particular task.
  • a kit of instruments can be produced, all of which are connectable with a common frame to enable the instruments to be head worn and therefore used by the person whilst performing the required task.

  • the retainers 80 hold a spring 82 and a ball 84 which is secured in place by crimping the end of the retainer to form a flange or bend 86 which prevents the ball 84 from being pushed completely out of the retainer 80 but allows the ball to partly project from the retainer as shown in Figure 3.

  • This enables different loupe assemblies to be interchanged with one another or replaced as is needed.
  • loupe assemblies are connected by the balls 84 and the sockets 46, the removal and replacement of the loupe assemblies can be achieved quickly and very easily simply by clipping in and pulling out the loupe assemblies as is needed.

  • the eccentric lobes 56 engage the part circular surface 43 of the groove 42 and wedge against the surface 43 of the groove 42, thereby providing sufficient friction to hold the loupes in the raised position so the loupes will not fall down as the user walks around or otherwise moves.
  • the loupes are simply pivoted downwardly so that the shaft 50 rotates on the pivot joint formed by the balls 84 and sockets 46 to move the eyepieces into the line of sight.
