Technical engineering line drawing, black and white, 3/4 view of a complete pair of mechanical stilts. Structure extends from upper thighs to 40 cm below the feet. Slightly bent stance, no human legs. Visible components: tubular frame, joints, pivot axes, tension rods, straps at thigh, knee, and foot. Air shock absorbers under the 15-degree inclined foot platforms, rear-angled by 15°. Reinforcement rods and linkages visible. Vertical height scale to the right marked up to 2.7 m. Fine annotations labeling parts: “Air shock absorber,” “Main pivot axis,” “Strap,” “Inclined foot platform,” “Lower extension (40 cm).” Clean white background, blueprint-style technical clarity, no color, no decorations.
