Abstract

A wear plate assembly for mounting on a substrate to be protected includes a support plate having a first surface and an opposing second surface and a wear plate having a wear surface and an opposing attachment surface affixed to the first surface of the support plate, wherein the wear surface is a continuous, uninterrupted surface. The assembly also includes a shaft having a base portion attached to the second surface of the support plate, a head portion distal from the base portion and a groove formed between the base portion and the head portion. The assembly also includes a retainer spring adapted to be received in the groove on the shaft, wherein the retainer spring includes a plurality of compressible tabs configured for cooperating with the substrate to releasably attach the wear plate assembly to the substrate.

First claim

What is claimed is:

1. A quick disconnect wear plate assembly for mounting on a substrate to be protected, the quick disconnect wear plate assembly comprising:
a support plate having a first surface and an opposing second surface;
a wear plate having a wear surface and an opposing attachment surface affixed to the first surface of the support plate, wherein the wear surface is a continuous, uninterrupted surface;
a shaft having a base portion attached to the second surface of the support plate, a head portion distal from the base portion and a groove formed between the base portion and the head portion; and
a retainer spring adapted to be removably mounted in the groove on the shaft, wherein the retainer spring includes a plurality of compressible tabs compressed radially inwardly to disengage from a bottom surface of the substrate and configured for releasably engaging the substrate to releasably attach the quick disconnect wear plate assembly to the substrate.

2. The quick disconnect wear plate assembly of claim 1 , wherein the wear plate is solid.

3. The quick disconnect wear plate assembly of claim 2 , wherein the wear surface of the wear plate is a planar surface.

4. The quick disconnect wear plate assembly of claim 3 , wherein the compressible tabs are spaced apart about a periphery of the retainer spring.

5. The quick disconnect wear plate assembly of claim 4 , wherein the wear plate has a greater wear resistance than the support plate.

6. A wear plate assembly for mounting on a substrate to be protected, the wear plate assembly comprising:
a support plate having a first surface and an opposing second surface;
a wear plate positioned on the first surface of the support plate;
a shaft extending from the second surface of the support plate, the shaft having a base portion attached to the second surface of the support plate, a head portion distal from the base portion and a groove formed between the base portion and the head portion; and
a retainer spring adapted to be removably mounted on the shaft, wherein the retainer spring includes a plurality of compressible tabs compressed radially inwardly to disengage from a bottom surface of the substrate and configured for releasably engaging the substrate to releasably attach the wear plate assembly to the substrate.

7. The wear plate assembly of claim 6 , wherein the wear plate includes a wear surface and an opposing attachment surface positioned on the first surface of the support plate.

8. The quick disconnect wear plate assembly of claim 7 , wherein the wear plate is solid.

9. The wear plate assembly of claim 7 , wherein the wear surface of the wear plate is a planar surface.

10. The wear plate assembly of claim 9 , wherein the wear surface of the wear plate is a continuous, uninterrupted surface.

11. The wear plate assembly of claim 6 , wherein the wear plate is affixed to the support plate.

12. The wear plate assembly of claim 6 , wherein the compressible tabs are spaced apart about a periphery of the retainer spring.

13. The wear plate assembly of claim 6 , wherein the wear plate has a greater wear resistance than the support plate.
