## Abstract

The invention is a joint cover assembly and related method for covering a gap adjacent an edge of a panel that covers a sub-surface. The assembly includes a molding having a foot, a first arm, and a second arm. The foot is positioned along a longitudinal axis of the molding, wherein the first arm, and optionally the second arm, extend generally perpendicularly to the foot. A tab depends from at least one of the first and second arms. At least one of the tab and the foot engage a track in order to position the assembly over the gap. The method includes placing the foot in the gap, pressing the respective panel engaging surfaces into contact with respective panels, and configuring at least one of the tab and the foot to cooperate to retain the molding in the gap when the assembly is installed.

## Claims

### Claim 1

A joint cover assembly for covering a gap between two floor elements, the assembly comprising:
a first molding element comprising an upper section comprising two arms having an exposed upper surface, the exposed upper surface comprising a decor, and the first molding element comprising a foot extending therefrom;
a separate second molding element comprising:
an upper surface configured for abutting the first molding element and positioning below one of the arms of the first molding element;
a lower surface having a groove; and
an exposed lateral surface; and
a track comprising:
a longitudinal section;
a gripping flange extending from the longitudinal section; and
an extension of the longitudinal section, the extension comprising a protrusion extending from the extension in the same direction as the gripping flange, the protrusion configured to be receivable within the groove on the lower surface of the second molding element, wherein the extension and longitudinal section are joined together by a break-away section, wherein the track grips both the foot and the second molding element.

### Claim 2 (depends on 1)

The joint cover assembly of claim 1, wherein the foot has a groove in an end of the foot, and the gripping flange extending from the longitudinal section of the track is shaped as an inverted T-element.

### Claim 3 (depends on 1)

The joint cover assembly of claim 1, wherein an underside of each arm is smooth.

### Claim 4 (depends on 1)

The joint cover assembly of claim 1, wherein the first molding element and separate second molding element are joined together.

### Claim 5 (depends on 1)

The joint cover assembly of claim 1, further comprising a shim.
