Abstract: The system of the invention involves an anti-slip alignment plate used with a mounting bracket for mounting a device, such as a flat video screen having video mounting holes. The anti-slip plate is aligned with protrusions, or other means, with a plurality engagement members on the bracket which receives the protrusions. Once the plate and bracket have mated in a particular position, a fastener can secure the plate, bracket and device together. The result is that the fastener need not be torqued so tightly because slippage is prevented by the engagement points on the anti-slip plate. Furthermore, the number of position available for the anti-slip plate to secure the device is often substantially greater than would be achieve if the bracket merely had series of adjacent mounting holes.

Abstract: The present invention involves a projector mount and leveling system for securely connecting and aligning a working unit, such as a projector, to the ceiling of a room. The present invention has a ceiling component with upper and lower sections, the upper section of the ceiling component attaches to a mounting surface, typically the mounting surface is a ceiling, a mounting bracket connects to the lower section of the ceiling component; a plurality of offset articulated legs, each offset articulated leg having a proximal end, and a distal end with a threaded leveling barrel opening; and threaded leveling barrels, wherein the offset articulated legs connect to the mounting bracket at the proximal end, and the offset articulated legs connect at the distal ends to a projector with the threaded leveling barrels.
