Aerobic step

摘要

An aerobic step includes a body having a middle exercise area and four sides. A maximum height of the body is positioned in the middle exercise area. The middle exercise area has a domed shape and curves downwardly to the four sides. The four sides define two longitudinal sides and two transverse sides. The middle exercise area includes a layer of material co-molded with and supported by a main body portion which promotes gripping and non-slippage. The layer of material includes a pattern of grooves. Two handles are defined along a lower portion of the body in the form of cutouts. An edge material is co-molded with and positioned on the lower edge of the body for contacting the ground. The body has a convex upper surface, and a concave lower surface which promotes stacking for storage, or for adding additional height by nesting two or more steps together.

主权项

1. An aerobic step comprising:
a support body having a lower edge portion extending downwardly from an outer periphery of an upper surface, the outer periphery having opposite longitudinal sides extending between opposite transverse sides, the longitudinal sides being longer than the transverse sides, the upper surface defining a pocket and a side body portion that extends between the pocket and the outer periphery, the lower edge portion being configured to engage a ground surface, the support body also defining an inner surface that faces in an opposite direction to the upper surface, the inner surface having a concave shape that follows a contour of the upper surface; a layer of material disposed in the pocket of the support body, the layer of material having a concavely curved inner surface that contacts a convexly curved surface of the pocket, the layer of material having a convexly curved outer surface that cooperates with the side body portion to define a convex shape of the aerobic step; wherein the convex shape of the aerobic step defines a domed longitudinal shape and a domed transverse shape with a highest point of each domed shape being located at a center of the layer of material.
