Benefits of technology

The present invention provides a strap securing structure for a sandal that avoids the problem of the strap becoming loose during activity. This structure is formed integrally with the strap, ensuring comfort and stability while wearing. Protrusions on the blocking portion of the joining plug increase friction with the sole structure, preventing the plug from becoming disassembled. This better secured assembly of the strap and sole structure can be achieved without increasing manufacturing compliance.

Problems solved by technology

However, the elasticity and flexibility of the plastic materials may adversely result in deformation of the joining plugs of the strap and / or the apertures of the sole while being stressed during the activity of the wearer.
This may result in unexpected disassembly of the strap and the sole structure and may cause the wearer to fall down during activity.

Abstract

An article of sandal includes a sole structure and a strap secured on the sole structure. The sole structure has an upper surface and a lower surface and an aperture penetrating through the sole structure and exposing an engaging surface between the upper surface and the lower surface of the sole structure. The strap is secured on the upper surface of the sole structure by having a joining plug assembled in the aperture. The joining plug has a blocking portion and a pillar portion connected to a top surface of the blocking portion. The top surface of the blocking portion has a plurality of protrusions that are in direct contact with the engaging surface of the sole structure.

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The present invention generally related to a footwear article, and more particularly related to a strap securing structure of a sandal.2. Description of the Prior Art[0002]A sandal is a type of footwear usually includes a strap secured on a sole structure to provide a room for accommodating the foot and retaining the sandal on the foot of the wearer. The sole structure of the sandal is therefore positioned between the foot and the ground to protect the foot from directly contacting the ground and also attenuate ground reaction force and lessen stresses the foot and leg bearing during walking, running and other ambulatory activities. Due to these advantages such as easy to wear, quick drying, simple structure and easy to clean, sandals have been widely used by people in their daily lives, especially in the occasions need temporary wearing, such as in the hospital, in the hotel or at the beach.[0003]The flip-flop is a kind of s...
