  • FIG. 2 79 PMENIEU 3,866,355
  • the present invention relates to the fabrication of metal windows with sash and window frames comprised of frame sections. More specifically, this invention is directed to metal windows and the like wherein the window frame unit includes a movable actuating element which passes around the frame for the purpose of actuating the movable members of various fittings. Accordingly, the general objects of the present invention are to provide novel and improved methods and appartus of such character.
  • the present invention overcomes the above briefly discussed and numerous other deficiencies and disadvantages of the prior art by providing a metal window assembly characterized by the ability of being mounted simply and quickly and further characterized by smooth reliable operation of the various movable fitting elements by means of a mechanism which is substantially maintenance free.
  • a window in accordance with the present invention employs, as an actuating element, a flexible perforated metal band which passes about the periphery of the window frame.
  • Movable fittings which cooperate with stationary fittings on the metal sash frame, are connected to the metal band actuating element at any desired point along the periphery of the window. The installation of the fittings is accomplished without the need for the actuating element itself to be provided with connecting points having a special configuration.
  • a window frame is provided about its outer periphery with a guide track for a flexible metal band; the band being perforated and facing the space between the window frame and the sash frame.
  • the window frame unit is partly of box-like construction.
  • Longitudinal window frame sections having such box-like construction are joined together by means of corner sections.
  • the corner sections have spaced legs which are received in the box-like portions of the longitudinal sections and the corner sections additionally are provided with a curved element located between the spaced legs.
  • the curved elements of the frame corner sections define curved extensions of the guide track whereby the metal actuating band may pass from one longitudinal window frame section to the next and transversely oriented longitudinal frame section without undergoing any abrupt changes in direction. Due to the manner of construction of the window frame corner sections, substantially the entire thickness of the frame sections in the direction of the window plane is employed to achieve a rounded guide track at the corners of the window without reducing the crosssection of the corner sections which determine the strength of the window frame corner joints.
  • the corresponding frame sections are each provided with at least a first groove which opens outwardly in a substantially vertical direction with respect to the plane of the window.
  • the window and sash frame sections are also provided with grooves which open in a direction parallel to the window plane.
  • the various fittings such as closure elements, tilt bearings and the like; are provided with suitably shaped projections which engage the grooves in the frame sections and the fixed position fittings are maintained in the desired position by means of self-tapping screws.
  • the movable fittings are provided with pins which engage perforations in the metal band actuating element.

  • the curved elements 18 are configured such that, with the corner joint section inserted into the frame box sections, the end points 19 of curved element 18 will be positioned adjacent the ends of the cutouts in the frame guide tracks 13 and element 18 will insure a steady transition from the guide track of a first frame section to the guide track of an adjacent transversely oriented frame section.
  • an inwardly facing ridge 3! is provided in each of box sections 2 as may best be seen from FIGS. 3b and 3c.
  • the ridge 31 will engage the side flange 1 6 of the corner joint section 15. This arrangement enhances the strength of the entire assembly with respect to stresses directed transversely to the plane of the window.
  • the metal band 14 positioned in the guide tracks 13 of the frame sections passes over the curved elements 18 of the frame corner joint sections 15.
  • the ends of the metal band 14 are connected to a tensioning device of the type shown in FIG. c.
  • the tensioning device can be moved to the left or right in the peripheral direction by means of an actuating mechanism operated with the aid of the window actuating lever to thereby cause the metal band 14 to move along the outer circumference of the window frame.
  • the corner joint sections 15 may be comprised of plastic but are preferably formed from die cast zinc since this material possesses excellent self-lubricating properties with respect to a steel band. Since, as briefly discussed in the preceding paragraph, the band 14 is preferably comprised of steel and will move along the outer circumference of the window frame, the providing of self-lubricating material in the corners will insure smooth operation of the actuating mechanism. In addition, as shown in FIGS. 1 and 2, the corner joint sections 15 are provided with holes whereby the sections 15 may be fixed to the ends of the longitudinal window frame sections by means of selftapping screws. For further reinforcement of the corner joints of the window frame, additional cornerjoint sections 15 having legs which cooperate with grooves 6 and 7 of the flange 5 may be provided. Such additional reinforcing members have not been shown in the drawing in the interest of facilitating understanding of the invention.
