Adjustable and Flexible Closure Assembly for Shoes With Variable Opening

This invention pertains to shoes, particularly the types of shoes suited for various athletic sports, such as running, tennis, soccer, basketball and jogging. However, it is also adaptable for dress shoes, golf shoes, football shoes, work shoes, outdoor shoes and other footwear.

The present invention relates to improvements in shoe construction utilizing an adjustable and flexible closure assembly to secure the shoe to the wearer's foot. In order to maintain the best fit and most comfort when wearing shoes using laces, it is necessary to retie them frequently because they become untied or loosen from the constant exertion of force against them. Shoes with buckles offer only a limited adjustability as permitted by the fixed spacing of holes in the strap for insertion of the rigid metal stud/latch on a buckle.

One of the major disadvantages in using laces is that when they become loose or break, the wearer can experience discomfort or even injury. This can happen especially in a fastaction sport requiring quick foot movements, such as basketball, tennis, racquetball, soccer, football and the like.

Shoes of the present invention pertain to low-cut and high-cut shoes, particularly sports shoes, which include an adjustable and flexible closure assembly to secure the shoe on the wearer's foot. The improvement of this invention can eliminate some of the problems found in conventional shoes which use laces only or buckles and similar fastening devices. The closure assembly can either totally or partially eliminate laces, buckles and other rigid fasteners as the fastening means for shoes. Whereas shoes using laces or buckles require both hands to fasten the shoe, the present invention enables the wearer to quickly adjust and firmly maintain the precise tautness desired by easily pulling the shoe uppers simultaneously to fasten the shoe, using only one hand. Most importantly, since the closure assembly of this invention can be easily manipulated using only one hand, no great dexterity is required to complete the fastening to firmly secure the shoe to the foot. Children and handicapped persons will also benefit from this improvement because they can fasten their shoes easily and quickly.

The closure assembly of the present invention includes co-acting hook and loop Velcro type fastening means, a fastener strap and an anchor means. The fastener strap has a fixed end permanently attached to one side of the shoe and a free end including at least one co-acting member of hook and loop fastening means. The anchor means or anchor strap has one end permanently attached to the opposite side of the shoe and a free end with an opening through which the free end of the fastener strap passes to fasten the shoe.

The improvement of this invention also includes a non-retractable U-type fastener strap bifurcated to form two members at the fixed end and a single member at the free end. The bifurcated members pass through separate openings on the side of the shoe forming the anchoring means and are attached adjacent the variable opening on the opposite side of the shoe. The hook and loop fastening means for the U-type fastener strap may be utilized in the same manner as the fastening means described hereinabove. The U-type fastener strap cannot be withdrawn after the two straps are inserted through the individual openings and attached to the shoe.

Among the objects of the present invention is the provision of a shoe having an adjustable and flexible closure assembly utilizing hook and loop fastening means which permits the wearer to adjust and maintain the precise desired tautness thereby obtaining a custom-fit and more comfort to the wearer's foot.
