Spring hinge for spectacle frame
 A pair of spectacles includes a mechanism for securing a spectacle temple to the frame. The mechanism includes a rod having one end pivotally coupled to the frame and one or more recesses formed in the other end. A block has one end contacted with the rod and has one or more ribs for engaging with the recesses of the rod. The block is fixed to the spectacle temple. A spring biases the block toward the rod so as to engage the ribs with the recesses in order to position the block relative to the rod such that both the block and the rod can be easily engaged into the spectacle temple.
