Abstract
The present technology relates to connection joints for surface coverings which includes but is not limited to floor coverings and building panels. Embodiments of the present technology include connection joints that are strong and allow for the use of less material than is needed for tongue and groove connection joints. In embodiments related to floor coverings, these advantages are accomplished by reducing total thickness of a floor plank while increasing the thickness of the wear layer relative to the overall thickness of the floor plank and still be able to maintain a structurally strong connection joint.

A floor plank comprising:
- a top side;
- a bottom side substantially parallel to the top side;
- a first edge extending from the top side to the bottom side comprising;
- a first contact side extending from the top side to a first terminal position between the top side and the bottom side;
- and
- a wedge shaped protrusion comprising;
- a first horizontal side extending from the first terminal position and substantially parallel to the top side;
- and
- a first angled side extending from the bottom side to the first horizontal side;
- wherein an angle formed between the bottom side and the first angled side is obtuse and an angle formed between the first horizontal side and the first angled side is acute;
- and
- wherein the first angled side includes a cleat located along the first angled side and spaced apart from the bottom side and the first horizontal side.
