A suspension system for a skate including a shoe and a truck device. The suspension system includes a four bar linkage having a forward mount connectable to the shoe; a rearward mount connectable to the shoe, a first double pivot mechanism interconnecting the forward mount with the truck device, and a second double pivot mechanism interconnecting the rearward mount with the truck device. A shock absorber subsystem biases the position of the truck device relative to the shoe.

Roller skate shock absorber system

A roller skate shock absorber system in at least two double pivot mechanisms spaced longitudinally from front to back along a skate shoe; a truck device including a plurality of wheels interconnected with the double pivot mechanisms; each of the double pivot mechanisms including a first pivot mounted to the skate shoe, a pivot member rotatably connected to the first pivot and having a second pivot rotatably attached to the truck device; and at least one resilient member disposed between the skate shoe and the truck mechanism for biasing at least one of the pivot mechanisms with its first and second pivots generally vertically aligned to provide a firm push-off force.
