Abstract
Abstract A right angle extension tool is disclosed for interconnection with a socket wrench. The tool includes an elongated cylinder with a shaft disposed therein. The shaft has a socket box connected to a first end for interconnection with a socket wrench, and has a right angle drive mechanism on a second end. A socket pin is connected to a shaft extending from the right angle drive mechanism. The shaft includes one or more mechanisms, such as articulated joints, to permit the extension tool to flex so difficult to reach bolts or the like can be removed or tightened.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
132 words
A right angle extension tool for interconnection with a socket wrench, comprising: an elongated cylinder including means for permitting flexure thereof; a shaft disposed within the elongated cylinder and having a first end extending out from the elongated cylinder, the shaft including means for permitting flexure thereof; wherein at least one portion of the flexible elongated cylinder includes means for permitting compression and expansion thereof, and the shaft comprises an inner shaft reciprocally received within an outer shaft to permit longitudinal extension thereof; a socket box connected to the first end of the shaft for interconnection with a socket wrench; right angle drive means connected to a second end of the shaft independently from the shaft; and a socket pin connected to an outwardly extending shaft of the right angle drive means.
Claim 2
Dependent Claim
