  • Patent number: 6513194
    Abstract: An adjustment assembly enables lateral adjustment of the position of a pivot connection of a first member relative to a second member in a window assembly having a first member, a second member, and a rotatable pivot-mounting element. The pivot-mounting element includes a first pivot-mounting section with a first pivot axis operatively connected to the first member and a second pivot-mounting section operatively connected to the second member. The second pivot-mounting section has a second pivot axis that is generally parallel to and offset from the first pivot axis. An engager section is located intermediate the pivot-mounting sections. Finally, a locking member is provided to cooperate with the engager section and is movable relative to the engager section between a retention position and a release position.

  • Patent number: 6460294
    Abstract: A window and door opening and closing mechanism is disclosed which is particularly well suited for use in casement and awning window fittings. The opening/closing mechanism has a hinge arrangement with two linked arms pivoting from a runner which may be attached to the window frame. One or both of the pivoting arms is mounted to the runner on a slider which is movable along the runner in relation to the pivot mounting of the other arm. The mechanism is operable by way of a cable or cord which has portions wound around a spool which is rotatable by the user. Winding the spool in one direction applies a tension to one portion of the cord or cable to apply a force between the pivot mountings of the arms and draw them together on the runner to open the window by pivoting the arms outwardly from the window frame. Winding the spool in the other direction applies a tension to another portion of the cord or cable coupled to one of the arms to draw them back toward the runner and close the window.
