  • Resilient rolling torus for a load-cushioning device
    Patent number: 5005811
    Abstract: A device for cushioning impact loads is described as employing unique rolling rubber rings for compressively engaging adjacent conical surfaces of the device as the surfaces come closer together. The ring has a pair of longer toroidal segments which are connected by a pair of shorter toroidal segments which have cross-sections which are substantially smaller than those of the longer segments, such that the ring can be designed to resist different lateral forces imparted to the ring.
