Aircraft
FO was using company-provided temporary mounting tray (with large rubber strap on bottom of tray) to hold company-provided iPad. This aircraft requires the mounting tray to be placed on top of now-deactivated electronic flight bag (EFB) display mounted below FO's forward side window. As FO rotated aircraft during takeoff roll at Vr; nose wheel vibration caused the EFB display to flop over; allowing the iPad and metal mount to hang away from the EFB display and CONTACT THE CONTROL YOKE DURING ROTATION. To emphasize: The iPad assembly was restricting rearward motion of the control column during the rotation maneuver. FO had to immediately bat away the iPad and associated equipment with his right hand to continue the rotation maneuver. The iPad assembly would not remain up and away; but instead fell down again against the control yoke. FO continued to fly the aircraft with the left hand; and had to HOLD the iPad and assembly out of the way until the aircraft was established in proper takeoff attitude. Once the vibration of the spinning nose wheel had dissipated; the iPad assembly was able to remain upright on its own. After the takeoff and climb; FO removed the mounting bracket and repositioned it vertically; so that it could not impact the control yoke.
B747 First Officer reported that during the rotation maneuver at takeoff the iPad mounting bracket fell down and restricted movement of the yoke.
