Expandable stand-alone shelving assembly

An expandable shelf assembly comprising:

• an aperture configured for mounting the expandable shelf assembly;
• a first half including a surface, a top end, and a bottom end, and a sidewall that extends from each of the top end and the bottom end of the first half;
• a second half including includes a surface and an angled portion that extends away from the surface of the second half;
• and
• an internal mechanism, wherein the internal mechanism includes:
• a slide disposed on each of the top end sidewall and the bottom end sidewall of the first half,
• a reinforcement bar that connects the top end sidewall and the bottom end sidewall of the first half, and
• a stop disposed on the reinforcement bar nonparallel to the reinforcement bar,
• wherein:
• the second half is slidably received within the first half such that the second half is partially encapsulated by the first half and the internal mechanism, and
• when the first half and the second half are slid apart a predetermined distance, the stop of the internal mechanism is configured to engage with the angled portion of the second half to prevent the second half and first half from sliding apart beyond the predetermined distance.

An expandable shelf assembly comprising:

• an aperture configured for mounting the expandable shelf assembly;
• a first half;
• a second half;
• an internal mechanism, wherein:
• the aperture is disposed through a corner of at least one of the first half or the second half,
• the first half includes a surface, a first end, a second end, a top end, a bottom end, a sidewall that extends around the surface of the first half at the first end, the top end, and the bottom end of the first half,
• the second half includes a surface, a first end, a second end, a top end, a bottom end, a sidewall that extends around the surface of the second half at the second end, the top end, and the bottom end of the second half, and an angled portion that extends downwards from the surface of the second half at the first end of the second half,
• the internal mechanism includes a slide disposed on each of the top end sidewall and the bottom end sidewall of the first half, reinforcement bars that connect the slides, and a stop disposed across the reinforcement bars,
• the second half is slidably received within the first half such that the second half is partially encapsulated by the first half and the internal mechanism, and
• when the first half and the second half are slid apart a predetermined distance, the stop of the internal mechanism is configured to engage with the angled portion of the second half to prevent the second half and first half from sliding apart beyond the predetermined distance;
• and
• a locking clip configured to connect the first half and the second half such that the first half and the second half are held in place relative to each other.
