Abstract

The present invention provides a stair edging component or nosing assembly comprising a plurality of elongate inserts, each insert comprising a main body portion having a tread surface and a coupling interface to couple the insert to the stair, and an opening extending through the length thereof, a locating spacer located between each pair of inserts, and a tensioning means extending through the opening in each insert and along the length of the stair edging component.

Claims

1. An elongate insert for a leading edge of a stair, the insert comprising:

a main body having a tread surface and a coupling interface to couple the insert to the stair, and

an opening extending through the length thereof.

2. An insert as claimed in claim 1, further comprising a locating recess at at least one end thereof.

3. An insert as claimed in claim 1, comprising a locating recess at each end thereof.

4. An insert as claimed in claim 1, wherein the coupling interface comprises at least one hooking part for securing the insert to the stair and at least one recess for engagement with a lip of the stair.

6. An insert as claimed in claim 1, wherein the coupling interface comprises at least one clamping recess adapted to receive a positioning device during moulding of the stair.

7. An insert as claimed in claim 1, wherein the insert is formed substantially of concrete, with a pipe defining the opening.

8. An insert as claimed in claim 1, wherein the tread surface of the insert is at least slightly concave.

5. (canceled)

9. A stair edging component comprising:

a plurality of elongate inserts, each insert comprising main body with a tread surface and a coupling interface to couple the insert to the stair, and an opening extending through the length thereof,

a locating spacer located between each pair of inserts, and

a tensioning means extending through the opening in each insert and along the length of the stair edging component.

10. A stair edging component as claimed in claim 9, wherein each locating spacer is provided with an opening therein, corresponding to the opening in each insert.

11. A stair edging component as claimed in claim 9, wherein the profile of each insert is substantially similar to the profile of each locating spacer.

12. A stair edging component as claimed in claim 9, wherein at least one surface of each locating spacer is at least slightly concave.

13. A stair edging component as claimed in claim 9, wherein the tread surface of each insert is at least slightly concave.

14. A stair edging component as claimed in claim 9, wherein the tensioning means is a wire or cable.

15. A stair edging component as claimed in claim 9, wherein the tensioning means is secured by way of one or more crimping ferrules.

16. A stair edging component as claimed in claim 9, wherein the stair edging component further comprises a locating spacer at each end thereof.

17. A stair edging component as claimed in claim 9, wherein each insert is further provided with one or more locating pins.

18. A mould assembly for forming an insert for a leading edge of a stair, the mould assembly comprising:

first and second mould extrusions shaped to provide a tread surface and a coupling interface to an insert moulded therein, and

one or more spacer locating formers located within the first or second mould extrusion and adapted to locate sections of pipe within the mould extrusions.

19. A mould assembly as claimed in claim 18, shaped to provide a tread surface of the insert with a slightly concave surface.

20. A method of forming a stair edging component or nosing assembly, the method comprising:

providing a plurality of inserts, each insert comprising a main body having a tread surface and a coupling interface to couple the insert to the stair, and an opening extending through the length thereof,

providing a locating spacer between each pair of inserts, each locating spacer being provided with an opening,

extending a tensioning means through the opening in each insert and in each locating spacer,

tensioning the tensioning means until the plurality of inserts and the locating spacers are held firmly together.

21. A method as claimed in claim 20, wherein tensioning of the tensioning means is achieved using a tensioning jig and the tensioning means is held in place after tensioning by means of one or more crimping ferrules.
