摘要:
A connecting structure connects a hollow first tube and a hollow second tube. The second tube comprises internal screw threads. The connecting structure further includes a hollow connecting sleeve connecting the first tube to the second tube. Portions of the first tube and the second tube are positioned within the connecting sleeve. The first tube is movable within the connecting sleeve in a direction parallel to an internal surface of the first tube. The connecting structure further includes a hollow connecting tube connected to an internal surface of the second tube and positioned within the first tube. The connecting tube comprises a first end having external screw threads engaged with the internal screw threads of the second tube. At least one O-ring is located on an external portion of a second end of the connecting tube, opposite the first end.

摘要:
A sandal having easily adjustable straps that allows a user to quickly modify the tightness of the sandal to adjust to the exact dimensions of the user's foot in order to secure the most comfortable grip for either casual or athletic activities. The sandal exhibits a lightweight, robust, high strength, flexible construction including an elongated sole for supporting a foot, where the sole has a toe end and a heel end, a center toe strap, an interior strap, and an exterior strap. The toe strap is anchored in the toe and includes a distal end fixedly connected to a pivot means, such as a buckle, for securing and redirecting the side straps. The interior and exterior straps are fixedly secured near the middle of the sole of the sandal and extend forwardly with a slip fit through the front pivot means, then rearwardly back upon themselves. The interior and exterior straps have a free end portion on which a fastener device, such as a hook and loop strip is mounted, which allows it to be adjustably fashioned back upon itself. The adjustment of both the interior and exterior end straps allows the user to adjust the tightness of the sandal to prevent slippage and to secure the sandal snugly to the users foot, thereby minimizing the typical “flip-flop” movement and sound associated with nonadjustable sandals.
