Benefits of technology

The invention aims to provide a device that allows for tying a shoelace in a usual way and securing it with a knot before it is loosened. The device comprises a cushion made of soft and elastic plastic, which has a groove or contact mounting for the shoelace and the knot. The cushion has soft and elastic properties that restrict the relative movement of the shoelace, similar to rubber, and reduces the sliding properties of the shoelace on the cushion. The device prevents the loosening of the knot by braking the movement of the individual sections of the shoelace arranged in the groove in the cushion. The cushion forms a friction surface for the shoelace and the knot, and the friction surface area increases as the shoelace penetrates more into the cushion. This results in greater friction between the shoelace and the cushion.

Problems solved by technology

At the same time, the possibility is limited of the cushion extending in a disproportionate amount to the side, since the cushion is at least partially secured to the stable formed contact mounting.

Embodiment Construction

[0028]Represented in FIG. 1a is a system consisting of a device 1 and a shoe 2 with shoelaces 21, with which the device 1 is secured by the knotting of the shoelace 21 on the shoe 2. The device 1 comprises a two-part cushion 3, such that a groove 32 is formed between the two cushion parts 3. The material of the cushion 3 exhibits similar rubber-like properties as hardened silicone. The cushion 3 is provided such as to be knotted with the shoelace 21 on a shoe 2, in order to fix the knot 22 and the shoelace 21 and to prevent the loosening of the knot 22.

[0029]As is represented in greater detail in FIG. 1b, the two cushion parts 3 are arranged next to each other on the contact mounting 4. The device 1 lies with the contact mounting 4 on the shoe 2. In this situation, due to the pressure exerted when tying, the shoelace 21 penetrates with its knot 22 into the groove 32, and lies on the actual contact surface 41 of the contact mounting 4. Due to the elasticity of the cushion 3, a counte...

Abstract

A device for the securing of a knotted shoelace with at least one groove for placing the knot, wherein the device is to be secured by the knot and the shoelace on a shoe, and can be positioned between the knot and the shoe. It is intended by way of the device that the shoelace should be simple to tie and, at the same time, fixed securely. The device including at least one cushion made of a soft and elastic plastic, wherein the cushion includes the groove or the contact surface for the shoelace and for the knot.

Description

FIELD OF THE INVENTION[0001]The invention relates to a device for securing a knotted shoelace with at least one groove or one contact mounting for the placement of a knot, wherein the device is to be secured on a shoe by the knot and the shoelace, and can be positioned between the knot and the shoe.BACKGROUND OF THE INVENTION[0002]A generic device is already known from GB 2 447 314 A, which is secured on a shoe by means of a shoelace. This device comprises a receiver with a brake, with two opposed tooth arrangements. The brake groove delimits a space in which the two ends of the shoelace can be knotted, wherein the shoelaces are clamped in the brake.[0003]From WO 2008 / 007855 A1 a further generic device for securing a knotted shoelace is known, which is secured to a shoe by a shoelace. This comprises a receiver with side holes through which the shoelace ends are guided upwards onto the device. Two jaws provided on the receiver form a groove-shaped brake, in which the knot of the shoe...
