Mounting bracket

1. A bracket assembly comprising:

a stationary bracket for attachment to a pole or surface; the stationary bracket comprising:

a mounting plate having mounting holes for attachment to a surface or pole; and

two side walls extending perpendicular to the mounting plate, each side wall having a front hook and a rear hook on a top surface thereof; and

an adjustable bracket adapted to be mounted on the stationary bracket, the adjustable bracket having a front surface and two side walls, and comprising front and rear tabs on each side wall corresponding to the front and rear hooks, such that the adjustable bracket is attached to the stationary bracket in a preliminary mounting position by placing the tabs into the front and rear hooks.

2. The mounting bracket assembly according to claim 1 , wherein the stationary bracket has a plurality of adjustment apertures located along each side wall, and wherein the adjustable bracket has an angle adjustment wing located on each side wall, and wherein the mounting bracket assembly is rotated into a final mounting position from the preliminary mounting position by squeezing the angle adjustment wings together until the front tabs are released from the front hooks, rotating the adjustable bracket downward until a desired position is reached, and placing the front tabs into a closest one of the adjustment apertures in the stationary bracket.

3. The mounting bracket assembly according to claim 2 , wherein each side wall of the adjustable bracket has a screw aperture, and further comprising a securing screw, the securing screw being placed through the screw aperture and an overlapping adjustment aperture in the stationary bracket when the final mounting position is reached.

4. The mounting bracket assembly according to claim 2 , further comprising an axel aperture in the side walls of the stationary bracket and an axel aperture in the adjustable bracket, wherein the axel aperture in the stationary bracket overlaps the axel aperture in the adjustable bracket when the adjustable bracket is placed in the preliminary mounting position, and further comprising a pair of axel screws that are placed in through the overlapping axel apertures in the preliminary mounting position to support the adjustable bracket as it is rotated into the final mounting position.

5. The mounting bracket assembly according to claim 1 , further comprising a pole mounting assembly attached to the stationary bracket, the pole mounting assembly comprising:

at least one pole adaptor bracket, having a rear wall for attachment to a top or bottom of the stationary bracket, and a front section having a cut-out portion for accommodating a pole;

a pair of hooks inserted through apertures in said at least one pole adaptor bracket; and

a chain for securing the pole adaptor bracket on a pole via the hooks, wherein

the stationary bracket is mounted on a pole by connecting the at least one pole adaptor bracket to the stationary bracket, attaching said pair of hooks to the pole adaptor bracket such that the hooks extend away from the pole adaptor bracket toward the pole, wrapping a chain around the pole between the hooks, and securing the chain on the hooks to secure the stationary bracket to the pole.

6. The mounting bracket assembly according to claim 5 , wherein there are two pole adaptor brackets, two pairs of hooks and two chains.

7. The mounting bracket assembly according to claim 5 , wherein the hooks have threaded ends that are attached to the pole adaptor bracket with wing nuts, and wherein adjusting the wing nuts adjusts tension in the chain.

8. The mounting bracket assembly according to claim 1 , further comprising a speaker mounting bracket attached to the adjustable bracket, such that a speaker is mounted to a surface or pole by attaching the speaker to the speaker mounting bracket, attaching the stationary bracket to the surface or pole, and coupling the adjustable bracket to the stationary bracket.
