Abstract: A display screen mount apparatus. The apparatus includes a mounting frame positioned adjacent a vehicle ceiling. The mounting frame includes an attachment interface applying the weight of the apparatus to an external vehicle roof surface. A slide assembly includes a stationary end coupled to the mounting frame and an extensible member that is horizontally extensible from the mounting frame. A vertical support frame for supporting a display screen is pivotally coupled to the extensible member such that the support frame may be angularly rotated between a horizontal storage position and a vertical display position. A housing coupled to the support frame provides a housing recess for receiving the screen. The apparatus further includes an L-shaped fulcrum lever having a user-actuated arm and a spring-actuated arm. The user-actuated arm is coupled in parallel with the support frame. A pneumatic spring is coupled between and applies an expansive force between the slide assembly and the spring-actuated arm.
