Tilt-sliding mechanism for a window or door

Tilt-slide mechanism for a wing of a window or door which can be stopped in parallel positions and in this position can be shifted horizontally relative to a stationary frame, the mechanism having lower shift arms (10) and upper shift arms, at least one of the lower shift arms (10) being pivotally mounted to a lower transverse wing beam and to a traveling carriage (12), which shift arm can be brought in and out of a work connection by a control pivot pin (22) with a thrust bearing mounted on the stationary frame by means of the displacement motion of the wing, characterized by the fact that

• a supporting lever (18) has a lever arm (18) swingably hinged by a pivot pin (19) on the shift arm (10) in the area between a pivot pin (11) on the traveling carriage (12) and a pivot pin (14) on the wing, the lever arm (18) engaging a guide pin (20) so as to be swingably shiftable, the lever arm being connected to the wing in a guide slot (21) located on the wing, the guide slot being provided at one end with a detent recess (26) for the guide pin (20), while a second end of the lever arm is provided with the control pivot pin (22) which can be brought by a shift-and-lock motion of the wing into a work connection with the thrust bearing (23) mounted on the stationary frame, and said lever arm is therewith fixed so as to be placed in blocking engagement by the guide slot (21).
