Abstract: A sports vision training device is formed from a piece of material having a thickness sufficient to interfere with an individual's ability to look down at a sporting object. The piece of material has an adhesive coating or layer for positioning the material on an individual's cheek, preferably beneath an individual's eye, so that the piece of material interferes with the individual's ability to look down at the sporting object. The sports vision training device has a thickness sufficient to direct the individual's vision toward the field of play and up and toward at least one player on the field of play, and in some cases permitting intermittent and/or momentary glances at the sports object being controlled by the individual.

Abstract: A caster has a stationary hub with a bearing between the hub and a floor engaging wheel ring which allows the wheel ring to rotate relative to the hub. Torsional elastomeric elements mount the hub between spaced support arms radially inward of the bearing and are positioned eccentrically relative to the axis of rotation of the wheel ring so as to suspend the hub resiliently between the arms. In an alternate embodiment, the hub is cantilevered from a single support arm.

Abstract: A caster has two spaced apart wheels with an elastomeric torsional shock and vibration isolating suspension between them. The wheel axis is spaced longitudinally from a bearing axis to subject elastomeric disks positioned between the wheels to torsional shear stresses to help absorb shocks and vibrations. A snubber is provided for limiting the angular motion of the wheels about a bearing axis.
