Stair nosing assembly

摘要

An exemplary stair nosing assembly comprises an elongated base, a plate adhered to the base, and a cover temporarily covering the base and the plate. The base has at least one anchor portion extending downwardly from the upper portion for attaching to a lip of a tread pan and/or embedding in a concrete tread. The plate can have various features to enhance traction and visibility. The cover has front and rear lips that engage with front and rear edges of the base, and a weakened region adjacent the rear lip. When the assembly is embedded in a concrete tread, the cover is configured to fracture at the weakened region when the front lip of the cover is lifted upward from the base, leaving the rear lip remaining embedded in the concrete and allowing the rest of the cover to be removed to expose upper surfaces of the base and plate.

主权项

1. A stair nosing assembly comprising:
an elongated base comprising:
a generally horizontal tread portion having a first side and a second side that define an elongated side-to-side length, the tread portion further comprising a rear edge and a front end defining a front-rear direction that is perpendicular to the side-to-side length;a front portion extending downwardly from the front end of the tread portion and comprising a bottom edge; andat least one anchor portion extending downwardly from the tread portion and adapted to be embedded in a concrete tread of a stair; and an elongated cover mounted on the base and comprising:
an anchor portion adapted to be at least partially embedded in a concrete tread; anda cover portion adapted to temporarily cover the tread portion and the front portion of the base when the anchor portion of the base is embedded in a concrete tread, wherein the cover has a length substantially equal to the side-to-side length of the treat portion; wherein the cover has an elongated weakened region extending along substantially the entire length of the cover between the anchor portion of the cover and the cover portion of the cover, such that the cover is configured to fracture along the elongated weakened region when the cover portion of the cover is lifted from the base while the anchor portion of the cover and the base are embedded in a concrete tread.
