Abstract: A cushioning foot for a mobility aid includes an elastomeric or rubber foot configured to compress under axial and angular loading. A collar is affixed to the distal end of a shaft of the mobility aid and includes a flange for contacting and compressing the elastomeric or rubber foot under axial and angular loads.

Abstract: A dispenser for salt or other dry granulated material includes a combination of a container, a sprinkling cap and a flow-reducing element located between the sprinkling cap and an opening of the container. The flow-reducing element includes openings such that it allows fewer granules to pass when the container is inverted and shaken than would otherwise be allowed by the sprinkling cap alone. The combination of the sprinkling cap and the internal flow-reducing element provide the function of evenly releasing and distributing the granules in an expected and continuous manner, yet at a significantly lower rate than standard dispensers.

Abstract: 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.

Abstract: 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.
