Abstract

A wall protector includes a retainer that is adapted to be attached to a building wall and a cover of an impact resistant thermoplastic polymeric material in the form of a thin web of suitable cross-section attached to the retainer portion of the retainer. The cover includes at least one substantially straight portion of substantially uniform cross section along its length and having a face portion overlying the retainer and an integral transition portion that is integral with the straight portion has an end wall that curves smoothly away from the face portion of the straight portion from a rounded juncture with the face portion and overlies and conceals the end of the retainer. The integral transition portion may be configured as an end cap or a wall return piece that forms a transition between the straight portion and a wall surface or as a corner piece that joins sections of wall protectors mounted on walls that intersect at a corner.

Claims

1. A wall protector assembly comprising

a retainer adapted to be attached to a building wall, the retainer including two sides and two ends, and

a cover of an impact resistant thermoplastic polymeric material attached to a cover retainer portion of the retainer, the cover including at least one substantially straight portion of substantially uniform cross section along its length that includes two sides and two ends and having an external face portion overlying the retainer on the opposite side of the retainer from the building wall, wherein

the cover includes a flange portion integral with each side of the straight portion that conceals each side of the retainer and has a transition portion at least one of the ends of the straight portion that is integral with the straight portion and curves smoothly away from the external face portion of the straight portion from a rounded juncture with the external face portion to form an end wall which overlies and conceals the end of the retainer.

2. The wall protector assembly according to claim 1 wherein the integral transition portion is configured as an end cap.

3. The wall protector assembly according to claim 1 wherein the integral transition portion is configured as a wall return piece that forms a transition between the straight portion and a wall surface.

4. The wall protector assembly according to claim 1 wherein the integral transition portion is configured as a corner piece that joins sections of wall protectors mounted on walls that intersect at a corner.

5. The wall protector assembly according to claim 1 wherein the integral transition portion is configured as an end cap and forms a transition between the straight portion and the surface of a wall on which the wall protector is mounted by closing an opening that would otherwise exist at the end of the straight portion.

6. The wall protector assembly according to claim 1, the retainer of the assembly being mounted on a wall in spaced apart relation, wherein the integral transition portion is configured as an end return piece and makes a transition between the straight portion and the wall, thus closing a gap that would otherwise be left at the end of the straight portion between the wall and both the cover and the retainer on which the cover is mounted.

7. The wall protector assembly according to claim 6, wherein end wall of the integral transition portion has an external surface that is generated by moving of a straight line along a smoothly curved path, and the edge of the integral transition portion is planar.

8. The wall protector assembly according to claim 6, wherein the straight portion and the integral transition portion have substantially the same cross-sectional shape.

9. The wall protector assembly according to claim 6, wherein the shape of the integral transition portion is maintained and the integral transition portion is strengthened by a substantially rigid insert.

10. The wall protector assembly according to claim 9, wherein the insert is molded from a suitable polymeric material.

11. The wall protector assembly according to claim 9, wherein one end of the insert abuts the end of the retainer and the other end is substantially flush with the end of the cover.

12. The wall protector assembly according to claim 10, wherein one end of the insert abuts the end of the retainer and the other end is substantially flush with the end of the cover.

13. The wall protector assembly according to claim 1 wherein the integral transition portion is configured as a corner piece and makes a transition between the straight portion of the cover of a section of a wall protector mounted on one wall and a section of a wall protector that is mounted on an adjacent, intersecting wall.

14. The wall protector assembly according to claim 1 wherein the integral transition portion has an edge that is adapted to be positioned proximate to the wall surface and serves as either an end cap or an end return piece for the cover.

15. The wall protector assembly according to claim 1, the assembly being a crash rail or a feature rail and having a cover that includes a substantially planar web portion, wherein the integral transition portion has an external end surface that is a surface of revolution generated by a substantially straight line that is parallel to the plane of the web portion and perpendicular to an axis of the retainer.

16. The wall protector assembly according to claim 1, the assembly being a corner guard in which the retainer is adapted to be installed vertically on a wall corner and has portions overlying the wall surfaces that form the corner and the cover having a web portion of substantially L-shape in cross section, wherein the integral transition portion is generally L-shaped in plan and has an edge that is adapted to be positioned proximate to wall surfaces forming the wall corner.

17. The wall protector assembly according to claim 1, the assembly having first and second sections mounted on intersecting walls, wherein the integral transition portion of the cover has two substantially straight portions of the same cross section, one of the straight portions being received on a retainer mounted on one of the walls and the other straight portion being received on a retainer mounted on the other wall, wherein the integral transaction portion is intermediate and connects the straight portions, has a cross-sectional shape substantially the same as that of the straight portions and is smoothly curved along its extent.

18. The wall protector assembly according to claim 17, wherein the shape of the integral transition portion is maintained and the integral transition portion is strengthened by a substantially rigid insert.

19. The wall protector assembly according to claim 18, wherein the insert is molded from a suitable polymeric material.

20. The wall protector assembly according to claim 18, wherein one end of the insert abuts the end of the retainer on one wall and the other end abuts the retainer on the other wall.

21. The wall protector assembly according to claim 19, wherein one end of the insert abuts the end of the retainer on one wall and the other end abuts the retainer on the other wall.
