Cover device for floor joints has two bridging units each with two layers of projection such that each projection on one layer is in laminar contact with projection on other layer

摘要

The device includes two bridging units (2,3) along the length of each of which is a fitting portion comprised of projections. The projections on the bridging units mesh when the bridging units are brought together. Each fitting portion is comprised of two layers of projections such that each projection on one layer is in laminar contact with a projection on the other layer.
