Abstract

The present invention is an improved safety nosing component including a base element with channel member and a light emission element. The safety nosing component is manufactured by extrusion, co-extrusion, triple-extrusion, injection molding, insert injection molding, two-shot molding or a combination thereof. The present invention allows safety nosing components to be installed on architectural structures while also providing additional functionality.

Claims

1. A safety nosing component for securement to a stair architectural structure, comprising:

a base element including a main member and a support member,

the main member includes an inside surface, an outside surface, a first edge, a second edge, a third edge and a fourth edge;

the support member includes an interior surface, an exterior surface, a first border, a second border, a third border and a fourth border, wherein the main member and the support member unite at the second edge of the main member and the second border of the support member;

a texture element forming tread on the outside surface of the main member;

an attachment member on the inside surface of the main member, wherein the attachment member is a conduit structure including a nodular portion and a planar portion, the nodular portion including a plurality of continuous parallel lower ribs alternating between a plurality of continuous parallel extended ribs to form continuous parallel conduits, the planar portion including a projection and a continuous parallel rear conduit, the projection including a plurality of equally spaced apart apertures;

a channel member formed by a first boundary, a second boundary and a third boundary, wherein the channel member extends from a proximate end to a distal end and is positioned on the outside surface of the main member such that the proximate end terminates at the third edge of the main member and the distal end terminates at the fourth edge of the main member;

a substrate element, wherein the substrate element is of a flat-shaped cross-section including a top face, a bottom face, a first side, a second side, a third side and a fourth side; and

a light emission element including an upper face, a lower face, a first wall, a second wall, a third wall and a fourth wall;

the substrate element and the light emission element are positioned within the channel member such that the bottom face of the substrate element abuts the first boundary of the channel member,

the top face of the substrate element abuts the lower face of the light emission element and the upper face of the light emission element aligns with the outside surface of the main member,

the third side of the substrate element aligns with the third wall of the light emission element and the third side and the third wall further align with the proximate end of the channel member,

the fourth side of the substrate element aligns with the fourth wall of the light emission element and the fourth side and the fourth wall further align with the distal end of the channel member,

the first side of the substrate element aligns with the first wall of the light emission element and the first side and the first wall substantially abut the second boundary of the channel member, and the second side of the substrate element aligns with the second wall of the light emission element and the second side and the second wall substantially abut the third boundary of the channel member,

the attachment member on the inside surface of the main member facilitates assembly of the safety nosing component over an existing stair architectural structure, wherein adhesive is applied to the conduit structure and received within the at least one continuous conduit so that the safety nosing component directly assembles about and positively engages an existing stair architectural structure.

2. The safety nosing component for securement to a stair architectural structure of claim 1, wherein the first edge of the main member includes a bevel feature.

3. The safety nosing component for securement to an stair architectural structure of claim 1, wherein the substrate element is constructed of a material selected from the group comprising of a white polypropylene and a white polyethylene.

4. The safety nosing component for securement to a stair architectural structure of claim 1, wherein the base element is constructed of a material compounded with a glass fiber.

5. The safety nosing component for securement to an stair architectural structure of claim 1, wherein the base element is constructed of a material selected from the group comprising of polyurethane, polypropylene, and nylon-polypropylene alloy.

6. The safety nosing component for securement to a stair architectural structure of claim 1, wherein the texture element is a plurality of cleats.

7. The safety nosing component for securement to an stair architectural structure of claim 1, wherein the light emission element is between and including ½

inches to about and including 2½

inches in width.

8. The safety nosing component for securement to a stair architectural structure of claim 1 further comprising a texture element on the exterior surface of the support member.

9. The safety nosing component for securement to a stair architectural structure of claim 8, wherein the texture element is tread.

10. The safety nosing component for securement to a stair architectural structure of claim 8, wherein the texture element is an advertising constituent.

11. The safety nosing component for securement to a stair architectural structure of claim 1, wherein the texture element further comprises an advertising constituent.

12. The safety nosing component for securement to a stair architectural structure of claim 1, wherein the second boundary of the a channel member includes a first bevel feature and the third boundary of the channel member includes a second bevel feature, and the first side of the substrate element includes a first reverse bevel feature and the second side of the substrate element includes a second reverse bevel feature, and the first wall of the light emission element includes a third reverse bevel feature and the second wall of the light emission element includes a fourth reverse bevel feature, the first reverse bevel feature of the first side of the substrate element aligns with the third reverse bevel feature of the first wall of the light emission element and the first reverse bevel feature and the third reverse bevel feature mate with the first bevel feature of the second boundary of the channel member and the second reverse bevel feature of the second side of the substrate element aligns with the fourth reverse bevel feature of the second wall of the light emission element and the second reverse bevel feature and the fourth reverse bevel feature mate with the second bevel feature of the third boundary of the channel member such that the base element overmolds the substrate element and the light emission element thereby securing the substrate element and the light emission element within the channel member.
