Description
One type of vehicle suspensioll system whi.ch is becoming increasingly popular is the MacPherson strut suspension system. The MacPherson stru-t is an integral coil spring-shock absorber assembly which provides a li~htweight, compact vehicle suspension system. The MacPherson strut suspension system is disclosed in more detai].
in United Sta-tes Patent No. 2,62~,592 to E.S. MacPherson.
One of the problems associa-ted with the MacPherson s-trut assembly is tha-t the shock absorber unit typically wears out before the associ.ated coil spring.
Consequently, some MacPherson strut assemblies are manufactured with a constrllctioll which permi-ts the shock absorber unit to be readi.ly removed and replaced with a new shock absorber. ~n this type of MacPherson strut assembly, the shock absorber unit is typically maintained within a cylindrical shroud by means of a threaded fastener attached to one end of the cylindrical shroud. However, the problem with the threaded fasteners -~s that each manufacturer typically designs the fastener associated wi-th its suspension assembly to require a special tool c'onfiguration for removing the fastener.
A solution to this prob].em has been presented by one company, Branick Manufacturin~ of ~argo, North ; Dakota, which markets a tool that can be utilized to remove ~' the majority of threaded fasteners prPsent on the market today. The tool includes a handle portion having a means for supporting a separate socket unit specifically designed to remove a particular fastener configuration.
A plurality of individual sockets, each of which is designed -to remove a particular fastener, are typically provided with the handle assembly.
The present invention provides a tool for removing a threaded fastener oE the type employed to contain a vehicular shock absorber in an associated shroud, the shock absorber having a piston rod extending axially from one end of the shroud and through the associated fastener, the tool comprising a main body having a first keyway formed to extend along a portion of the outer surface on one side of the main body, a second keyway formed to extend along a portion of the outer surface on the opposite side of the main body, and a piston rod receiving channel extending comple-tely through the main body and terminating in each of the keyways, each of the keyways adapted to extend radially relative to the piston rod receiving channel, a pair of spaced apart elongate first keys mounted in the first keyway of the main body and adapted to slide radially relative to the piston rod receiving channel within the first keyway and means for locking the first keys within the first keyway at selected radial positions, each of the first keys having a first fastener engaging means provi.ded thereon for engagement with a first type of threaded ,~
fastener having a first tool engaging configuration, and a pair of spaced apart elongate second keys mounted in the second keyway and adapted to slide radially relative to the piston rod recei~ing channel within the second keyway and means for locking the second keys within the second keyway at selected radial positions, each of the second keys having a second fastener engagemen-t means difEerent fxom the first fastener engagement means provided thereon for engagement with a second type of threaded fastener having a second tool engaging configuration different from the first -tool engaging configuration.
The invention will become readily apparent to one skilled in the art when reading the following detailed description of a preferred embodimen-t of the invention when considered in light of the accompanying drawings, in which:
Figure 1 is a perspective view illustrating three sides of a main body of a tool embodying the features of the present invention;
