1,164,185. Window with alternative movement; operating windows etc.; hinges. W. WEBER. 21 June, 1967 [22 June, 1966], No. 28648/67. Headings E1J, E2F and E2M. In order to pivot a sash 2 about its lower horizontal side hopper-wise on the lower rail of the frame 1, it is coupled, under the control of a control rod 6, Fig. 3, operated by a handle 5, (in downwardly inclined positionbroken line Fig. 14) to an arm 4a of the lower hinge 4 mounted on the frame 1 by means of pins 45 on the control rod 6 engaging in slots on the arm 4a. At its upper end the control rod 6 is coupled by means of a pin 8 thereon engaging in a slot 10a having a curved termination in a bearing plate 9 fixed to the frame 1 and the pin 8 is connected to a pin 12 by a strap 11, the pin 12 moving in the slot 10b of the bearing plate 9 and connected with a control lever 13 linked by a pin 14 to a cross shaft lever 15 fixed to the cross-shaft 16 mounted on bearing plates 9. The lever 15 is linked by pin 17 to the extensor arm l8a, 18b which is controlled by a pin 21 on the arm 18a passing through a curved slot 19 in the lever 13 and a slot 20 in the lever 15 so as to rotate the lever 15 to extend or contract the extensor arm secured at the other end to the top of the sash. In the closed position of the window, the lever 15 is vertical in the locking position and the lug 22 thereon overlaps opposingly or face to face a lug 22 on the arm 18b, the pin 12 being at the bottom of slot 10b and the pin 8 at the top of the curved portion of shot 10a (Fig. 6a). The lug 22 is provided with a set screw 23 to compensate for tolerances and torsion of the cross shaft 16. To adapt the fitting, alternatively for pivoting the sash about a vertical edge, the arm 4a is decoupled from the sash by movement of the lever 5 to an upward vertical position (Fig. 15). In this case the control rod 6 is in an intermediate position with the strap 11 at the lower ends of the slots 10a, 10b (Fig. 6B). On the hinge side of the frame 1 the locking of the levers 15 and 18b on the locking side cause the arms 18a, 18b on the hinge side to collapse and the control lever 13 on the hinge side is connected through pin 30 with a control rod 31 for coupling the parts of the hinge 32, the arm 18b being connected to a hinge 3 fixed to the sash. The lower hinge 3 is a universal one providing for hing- ing about a vertical or horizontal axis. |
