Solid rod-shaped hinges and articles incorporating the same, such as collapsible sports articles, e.g., landing nets and snow sticks. A tubular landing net frame and handle incorporates at least three rod-shaped hinges. The hinge for the landing net comprises a cylindrical base element with locking shoulders on each end with pin rotatable, cylindrical and hooked extension elements. The extension elements have slots to accommodate the pins on the base element. Each extension element has a spring-loaded locking button for interacting with first locking apertures in the tubular net frame and handle. Each hook on the extension element is connected to a spring, anchored within the tubular frame. The folding procedure only requires a pull on the landing net frame at the joints to dislodge the locking buttons to expand the anchor springs and engage the locking buttons in second (limited in diameter) apertures of the tubular frame, thus to hold the net and handle in the folded position. The unfolding procedure requires minimum effort in dislodging the buttons to permit the expanded anchored springs to urge the opening of the landing net and handle. The snow stick incorporates at least two solid rod-shaped hinges. The folded snow stick can be conveniently carried in a case strapped to one's waist and thigh.
