KR20150028424A - Shoe lacing system which can tighten and untighten with footstep only - Google Patents

Abstract

The present invention relates to a shoe lacing device capable of tightening and untightening a shoe lace with footsteps only, which enables people with uncomfortable waist to conveniently use the device without bending the waist or using hands, and normal people to conveniently use the device in a funny way. Especially, the use method is very simple, thereby maximizing the convenience and pleasant elements compared to the conventional shoe lacing device. The shoe lacing device has excellent durability and is strong. Furthermore, the shoe lacing device is positioned on the bottom of a shoe, which makes no difference from the conventional shoe in appearance. The shoe lacing device of the present invention comprises a gear rotating when rotating the shoe; a fixation unit for maintaining the tightness of the shoe by preventing the reverse rotation, and releasing the tightness when pressing; and a wire for tightening the shoe.

Description

Technical Field [0001] The present invention relates to a shoe lacing system which is capable of tightening and loosening a shoe strap of a shoe by only a foot operation,

The present invention relates to a shoelace fastening device. More particularly, to a shoelace fastening apparatus for tightening or loosening a shoelace string through a foot operation when the shoe is put on or taken off.

In general, the shoe is designed to be tied to the hand with a shoelace through the hole in both sides. To tie a shoelace by hand, you must bend your waist or raise your legs. Such an operation is inconvenient to the general public, and is particularly difficult for an elderly person with a disability such as pregnant women or a disabled person, or a disabled person, and it is difficult for young children to tighten their shoelaces because they require sensitive hand movements.

Conventionally, various techniques such as a bore system and a speed race have been developed as techniques for simplifying tightening operations. However, these conventional techniques still have the inconvenience of bending back and operating by hand. Therefore, the conventional shoes can not improve the convenience for the user such as the elderly or the disabled who are pregnant or uncomfortable at the waist.

The present invention has been proposed in order to solve the above-mentioned problems, and it is an object of the present invention to provide a shoe for shoveling and loosening a shoelace using only a foot. It also aims to maximize convenience and simplicity for users with limited activities at the hands and waist.

In order to solve the above problem, the foot operation itself can be performed by squeezing and loosening the shoes without bending the waist. Put your feet on loose shoes, turn your feet against the floor, tighten your shoes, and release the tied ones by pressing the button on the side. To this end, it is characterized by a gear that rotates when the shoe is rotated, a fixing part that holds the shoe tightly by pressing against the rotation of the shoe, and a wire that tightens the shoe.

As described above, according to the present invention, the shoelace string can be fastened to the tightening device so that the shoelace can be tightened and loosened without using the hand without bending the waist. Therefore, elderly people, pregnant women, or obese people, such as abdominal obesity, people who can not bend the waist can easily wear off the shoes can be expected to take off, the general public can be fun and convenient to use.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The device 12 of the present invention is located at the bottom of the shoe.

The device of the present invention has an assembled structure of a fixed gear (6) and a rotating gear (2) that is connected to a wire and winds a shoelace.

The gear is connected to the shoe through the rotary shaft (1).

The gear 2 is connected to the wires 3, 10 so as to tighten the shoe.

The fixing device 6 of the present invention is connected to the spring 9 and is normally fixed only in the direction in which the gears are tightened and fixed so as not to be rotated in the unwinding direction, The fixing is released and the gear can be rotated in a direction in which the gear is released.

The gear of the present invention is fixed to the rubber plate 13 and rotates together with the bottom so as to increase friction force.

The user can tighten the shoelace while rotating the shoe on the floor with the foot.

The user can release the shoelace by pressing the fastening device (7).

Claims (6)

A shoelace fastening device located on the bottom surface of a shoe in contact with the ground A shoelace fastening device having a rubber plate (13) located on the bottom surface of the shoe When the bottom surface of the shoe is strongly brought into contact with the surface of the shoe, a strong frictional force is generated between the ground and the rubber plate 13. At this time, when the shoe is rotated by the foot, the rubber plate 13 and the rotary cog wheel 11 rotate due to frictional force. A shoelace string fastening device in which a shoelace string of a shoe is connected to a rotary cog wheel 11 to tighten a shoelace with a toothed wheel being rotated, A shoelace tightening device (10) in which the rotary gear (11) is rotatable in the opposite direction when the foot portion (7) Usually, a portion of the lower surface cover 14, which is not visible under the pressing portion 7 of the fixing device and is pressed by pressing the foot pressing portion 7, is bright with the other foot, and the rotating gear wheel 11) of the shoelace fastening device
