A self-locking device for hanging objects on a mounting surface is disclosed. The self-locking device includes a mounting bracket and a locking arm member engaged with a track portion of the mounting bracket. The track portion comprising a pair of guide portions, a pair of lip portions extending from a lower end of the guide portions, a pair of rotation portions extending from an upper end of the guide portions, and a slot extending between the pairs of guide portions, lip portions and rotation portions. The arm member being mated with the track portion such that the arm member is translatable along the track portion. The arm member comprising a tip portion, a base portion positioned at least partially within the slot, and at least one pair of projections extending from the base portion that engage with one of the pairs of guide portions, lip portions and rotation portions.

A self-closing and locking device for hanging objects on a mounting surface is disclosed. The device includes a mounting bracket and a locking arm member translatably engaged with an elongated track portion of the mounting bracket. The track portion comprises a pair of guide portions defining a slot therebetween, and rear recesses in a back side of the guide portions. The rear recesses comprise lower locking portions, and upper rotating portions that are deeper than the locking portions. The arm member comprises a base portion that is positioned within the rear recesses, and an arm portion that extends from the base portion and through the slot. The device is configured such that the arm member is oriented in a closed position when the base portion is engaged with the locking portions, and orientable in an open position when the base portion is engaged with the rotating portions.

A self-locking device having a locking mechanism is configured to lock an object. A mounting bracket contrivance includes a guide track implement for engaging the locking mechanism. A notch implement is configured to allow said locking mechanism to rotate out into an open position and a back stop is configured to hold the locking mechanism within the notch implement in an open position. A is configured to inhibit the locking portion from escaping the guide track implement. A base plate tool is used to mount the mounting bracket contrivance to a mounting surface and elevated the mounting bracket contrivance off the mounting surface.
