The present invention relates to a sneaker strap tightening device that allows the user to easily tighten the laces in the sneakers corresponding to the shoe to be laced, in particular, by the expansion force of the air tube filled by the air pump operation for the existing sneaker laces It was developed for the purpose of simplification and product refinement by acting as a tightening force and releasing the discharge valve from the tightening state by the user's pressing operation.

In the conventional case, the sneakers are worn in a state of fastening the sneakers straps in a slightly loose state without being closely adhered to the instep area so that the user can easily wear or remove the shoes in the form of straps (sneakers). When the activity is unstable to the user's feet, when you want to exercise a lot of activity when you wear a pair of sneakers and pulled the strings, followed by the inconvenience.

Recently, a shoelace fastener for easily fastening a sneaker strap fixed with a knot has been introduced in Korea Utility Model Publication No. 90-5224, and a lanyard such as a fishing line is adopted in a sneaker string hole. Although the pulling method is introduced by the rotary adjustment mechanism attached to the position, in reality, there is a limit in that the user can easily fasten the shoelaces and perform the release function easily when necessary, and in particular, the appearance of the shoe There was a fault to do.

Therefore, the present invention is described in detail by applying an air pumping system so that the user can easily tighten and release the tightening state for the shoe laces as follows.

In general, the basic concept of the present invention is that the sneaker strap is adjusted to be knotted so that the user can easily wear and take off the sneaker, or the user wears the sneaker and pulls the strap to tighten the shoe tightly so that the user can set the sneaker. The pumping operation of the air pump attached to the site, while the sneakers are worn, the expansion force of the air tube by the air pump acts as a tightening force, and if necessary, the air filled in the air tube is discharged to the outside to tighten the tightening force. Will be released.

To this end, an air pump for pumping air, a path for inducing pumped air, an air tube filled with air, and an air tube in the tightening or releasing direction of the end of the shoe according to the air filling and discharging conditions of the air tube. The tube housing performs the function of maintaining the directionality of the change in content, Arrangement of the sneaker strap so as to vary the degree of expansion and contraction of the air tube embedded in the tube housing, and the air of the air tube When the air discharge valve that can be discharged to the outside by the operation is installed to be opposed to the strap part of the sneaker, the air pump fills the air and the end of the sneaker acts as a tightening force. It is a technical feature of the present invention that a fastening device is attached to the sneaker so as to perform the function of releasing the tightening force of the shoe laces. All.

Hereinafter, the configuration and operation effects according to the accompanying drawings showing the embodiments will be described in detail.
