Abstract

A shield assembly for a shaft includes a first tubular section having a first end and a second end and a second tubular section having a first end and a second end. The first and second tubular sections are each hollow receiving the shaft. The first tubular section includes a first outer diameter and the second tubular section includes a second outer diameter, the first outer diameter being greater than the second outer diameter. The first tubular section and the second tubular section are telescopically coupled to one another where the second tubular section is movably disposed at least partially within the first tubular section.

First claim

The invention claimed is:

1. A shield assembly for a shaft, comprising:
a first tubular section comprising a first body having a first end and a second end, the body defining a first hollow channel therethrough from the first end to the second end for receiving the shaft; and
a second tubular section comprising a second body having a first end and a second end, the body defining a second hollow channel therethrough from the first end to the second end for receiving the shaft;
a shield coupler for coupling to the first tubular section, the shield coupler including a larger portion including a plurality of tabs extending from a shield coupler end along a length of the shield coupler and, a space formed in the shield coupler end between two of the plurality of tabs, the space providing a location for receiving a tab of another shield coupler;
wherein, the first tubular section comprises a first outer diameter and the second tubular section comprises a second outer diameter, the first outer diameter being greater than the second outer diameter;
further wherein, the first tubular section and the second tubular section are telescopically coupled to one another where the second tubular section is movably disposed at least partially within the first tubular section.

2. The shield assembly of claim 1 , wherein, the first tubular section and the second tubular section are telescopically coupled to one another to form a collapsed configuration and an extended configuration, the collapsed configuration comprising a smallest length of the shield assembly and the extended configuration comprising a largest length of the shield assembly.

3. The shield assembly of claim 1 , further comprising a shaft disposed within the first and second hollow channels, the shaft comprising a shaft length;
wherein, the first tubular section and second tubular section are adjustably and telescopically positioned relative to one another so that a length of the first and second tubular sections is approximately the same as the shaft length.

4. The shield assembly of claim 1 , wherein the first tubular section and second tubular section are removably coupled to one another such that the second tubular section slides in from one end of the first tubular section and out an opposite end of the first tubular section.

5. The shield assembly of claim 1 , wherein the first end of the second tubular section comprises a smaller diameter portion that is less than a larger diameter portion of a second outer diameter of the second end of the second tubular section.

6. The shield assembly of claim 1 , wherein the shield coupler comprises a narrow portion including one or more tabs;
wherein, the first tubular section comprises one or more apertures formed therein for receiving the one or more tabs on the narrow portion of the shield coupler in a quick-connect manner.

7. The shield assembly of claim 6 , further comprising a shield coupler for coupling to the second tubular section, the shield coupler comprising a narrow portion including one or more tabs and a larger portion comprising one or more tabs;
wherein, the second tubular section comprises one or more apertures formed therein for receiving the one or more tabs on the narrow portion of the shield coupler in a quick-connect manner.
