Abstract
An air step board for health is disclosed. The step board has an upper plate on the upper surface of a board frame, and a shock absorbing leg on a corner of an underside of the board frame. The board frame is formed using a synthetic resin material through injection molding such that a seating part is provided on the upper surface of the board frame, and a reinforcing rib is provided in the seating part to reduce a weight of the board frame and impart sufficient strength. A handle is provided on at least one side of the board frame. In this invention, the board frame having the reinforcing rib is manufactured through injection molding, thus enhancing the durability of the board frame, permitting mass production, and ensuring easy workability, and a reinforcing plate is provided between the reinforcing ribs and the upper plate, thus reliably withstanding shocks.

5. An air step board for health, having an upper plate on an upper surface of a board frame and a shock absorbing leg provided on a corner on an underside of the board frame and stably supporting the board frame, wherein the shock absorbing leg comprises:
-
at least one ventilation opening formed in an upper end of the shock absorbing leg, and allowing air to circulate in and out of the shock absorbing leg as it is compressed or extended; and an air circulation unit installed in the ventilation opening, and comprising; a perforated member functioning to prevent a noise from being generated when air circulates in and out of the shock absorbing leg; and a casing having a hole to allow air to flow from an interior or exterior of the shock absorbing leg through the ventilation opening and the perforated member, and surrounding the perforated member so as to prevent the perforated member from being removed from the ventilation opening by the air flowing through the ventilation opening. - View Dependent Claims (6, 7, 8, 9, 10)
