Abstract
An armored window drive mechanism includes a window unit containing a bullet resistant glass, composite or polymeric material window positioned within a window frame of a vehicle. A motorized window mechanism is connected to a door structure of the vehicle and acts to raise or lower the window unit. A mechanism connector is adapted to convert an axial rotational force generated by the window mechanism to a lifting and a lowering force acting directly at a lower face of the window frame.
Claims15
An armored window drive mechanism including:
- a window unit containing a bullet resistant window positioned within a window frame;
- the window frame is slidably received and guided within opposed side rails each having a facing of a low frictional coefficient material, the opposed side rails contained between opposed flanges, the side rails including the flanges having a width proximate to a bottom of the side rails that is greater than a width proximate to a top of the side rails, thereby directing the window unit to displace up and down, and also toward and away from an inside space of the vehicle as the window unit is displaced;
- a motorized window mechanism connected to a door structure of a vehicle energized to raise and lower the window unit;
- and
- at least one mechanism connector converting an axial rotational force generated by the window mechanism to a lifting and a lowering force acting directly at a lower face of the window frame.
An armored window drive mechanism including:
- a window unit containing a bullet resistant window positioned within a window frame, the window frame slidably received and guided within opposed track channels, the track channels each having:
- a width proximate to a bottom of the track channels that is different than a width proximate to a top of the track channels, thereby directing the window unit to displace up and down, and also toward and away from an inside space of the vehicle as the window unit displaces;
- and a pad of a low frictional coefficient material;
- a motorized window mechanism connected to a door structure of a vehicle energized to raise and lower the window unit;
- at least one mechanism connector converting an axial rotational force generated by the window mechanism to a lifting and a lowering force acting directly at a lower face of the window frame;
- and
- a spring biasing device in contact with each of the pads, each of the pads biased into constant contact with a perimeter frame member of the window unit by a biasing force of the spring biasing device;
- wherein between a closed and an open position of the window unit, the window mechanism displaces the window unit downward by at least 75% of a height of the window unit.

- a pad of a low frictional coefficient material provided with each of the track channels;

- a motorized window mechanism connected to a door structure of a vehicle energized to raise and lower the window unit;
- and
- at least one mechanism connector converting an axial rotational force generated by the window mechanism to a lifting and a lowering force acting directly at a lower face of the window frame, the at least one mechanism connector including a first mechanism connector connected between the window mechanism and the door structure and a second mechanism connector connected between the window mechanism and the window frame;
- wherein the window mechanism connected to the mechanism connector will positively retract or raise the window unit with the vehicle in a non-upright position.
