Abstract
A spring perch assembly for automatically centering a load applied to a spring is provided. The assembly includes a body portion and a base portion which when engaged may tilt relative to one another. When disposed between a spring and an applied load, the assembly automatically centers the load along the spring's natural centerline.
Claims21
1-20. (canceled)
A load-centering perch and coil spring assembly, comprising:
- a coil spring having at least one end coil, wherein said spring defines a natural centerline passing through said end coil;
- a base member engaged with said end coil, wherein said base member is tiltable with said end coil relative to a natural centerline of the spring during spring compression;
- a body member engaged with a load having a substantially fixed load direction, wherein said body member is in substantially fixed alignment with the load;
- wherein said body member and said base member are pivotally engaged;
- and,
- wherein during spring compression said base member tilts with the spring end coil relative to said spring natural centerline and pivots with respect to said body member to redistribute the applied load across the spring end coil.

A load-centering perch assembly for a coil spring in a vehicle suspension system, comprising:
- a vehicle suspension shock absorber having a coil spring with at least one end coil, wherein said spring defines a natural centerline passing through said end coil, wherein said shock absorber includes a piston having a natural centerline;
- a base member engaging said end coil;
- a body member having a fixed load direction attached to said vehicle suspension shock absorber;
- wherein said body member and said base member are pivotally engaged;
- and,
- wherein said base member is tiltable with said end coil of said spring relative to the natural centerlines of the spring and said piston and pivots relative to the fixed load direction and said body member during spring compression.
3 more elements
A load-centering perch and coil spring assembly, comprising:
- a coil spring having opposing end coils, wherein said spring defines a natural centerline passing through said end coils;
- a first perch assembly having a first base member engaged with a first end coil of said coil spring, wherein said base member is tiltable with said end coil relative to a natural centerline of the spring during spring compression and a first body member for engaging a load having a substantially fixed load direction, wherein said first body member is in substantially fixed alignment with the load, wherein said first body member and said first base member are pivotally engaged;
- and, wherein during spring compression said first base member tilts with said first spring end coil relative to said spring natural centerline and pivots with respect to said first body member to redistribute the applied load across said first spring end coil;
- and,
- a second perch assembly having a second base member engaged with a second end coil of said coil spring, wherein said base member is tiltable with said end coil relative to a natural centerline of the spring during spring compression and a second body member for engaging a load having a substantially fixed load direction, wherein said second body member is in substantially fixed alignment with the load wherein said second body member and said second base member are pivotally engaged;
- and, wherein during spring compression said second base member tilts with said second spring end coil relative to said spring natural centerline and pivots with respect to said second body member to redistribute the applied load across said second spring end coil.
