Patent Images
1. A modular threshold comprising:
- at least three components, a first toe, a second toe, and a third component chosen from the group including risers, plates, thermal breaks, sliding door tracks, and rolling door tracks;
wherein each said component includes at least one flange, projecting rib, or receiving channel, so that said flange or said projecting rib is placed into a receiving channel to lock said at least three components firmly together, andsaid receiving channel includes two side walls, each said side wall comprising an upper side wall and a lower side wall, such that said receiving channel has a profile that, from an opening of said receiving channel, first increases in cross sectional area to a midline, then decreases in cross sectional area until a bottom planar surface of the channel has the same width as said opening of said receiving channel,said projecting rib having a profile which corresponds to that of said receiving channel;
such thatsaid projecting rib is received in said receiving channel, thereby locking said a least three components firmly together.

Abstract
A modular threshold system that includes multiple components that are joined together to form various threshold configurations. Each component includes an irregularly shaped channel adapted to receive a conforming projection on a second component. The channel and the projections are shaped so as to allow the components to be installed serially, while providing a secure joint between the components.
