A hinge bracket assembly comprising: an anchor plate including a retention member extending perpendicular to the anchor plate, wherein the anchor plate defines a first receiving aperture, the anchor plate further including a stop extending from it; a hinge plate aligned with the anchor plate and including a hinge arm and a protrusion, the protrusion extending from an edge of the hinge plate opposite the hinge arm, wherein the hinge plate defines a second receiving aperture aligned with the first receiving aperture when the protrusion is received by a space defined by the retention member; and a locking arm rotatable between an unlocked position and a locked position and configured to be at least partially received by the first and second receiving apertures (22, 42) to couple the anchor plate and the hinge plate, wherein the locking arm includes a first portion configured to be at least partially received by the first and second receiving apertures (22, 42), and a second portion configured to abut the stop extending from the anchor plate when the locking arm is in the locked position, whereby: - the hinge plate defines a notch, - the stop is received by the notch when the hinge plate is coupled with the anchor plate, - the hinge plate includes a generally rounded protuberance extending from an upper surface of the hinge plate and - the second portion of the locking arm abuts the protuberance and the stop when the locking arm is in the locked position. an anchor plate including a retention member extending perpendicular to the anchor plate, wherein the anchor plate defines a first receiving aperture, the anchor plate further including a stop extending from it; a hinge plate aligned with the anchor plate and including a hinge arm and a protrusion, the protrusion extending from an edge of the hinge plate opposite the hinge arm, wherein the hinge plate defines a second receiving aperture aligned with the first receiving aperture when the protrusion is received by a space defined by the retention member; and a locking arm rotatable between an unlocked position and a locked position and configured to be at least partially received by the first and second receiving apertures (22, 42) to couple the anchor plate and the hinge plate, wherein the locking arm includes a first portion configured to be at least partially received by the first and second receiving apertures (22, 42), and a second portion configured to abut the stop extending from the anchor plate when the locking arm is in the locked position, whereby: - the hinge plate defines a notch, - the stop is received by the notch when the hinge plate is coupled with the anchor plate, - the hinge plate includes a generally rounded protuberance extending from an upper surface of the hinge plate and - the second portion of the locking arm abuts the protuberance and the stop when the locking arm is in the locked position. - the hinge plate defines a notch, - the stop is received by the notch when the hinge plate is coupled with the anchor plate, - the hinge plate includes a generally rounded protuberance extending from an upper surface of the hinge plate and - the second portion of the locking arm abuts the protuberance and the stop when the locking arm is in the locked position.
