Description

The field of technology.

The technical solution relates to light industry, to the shoe industry, in particular to the production of accessories for corded shoes, namely to clamps or clips for fixing stretched laces.

The level of technology.

Clips for shoelaces are well known, they are designed to prevent spontaneous untying of shoelaces, tangling of shoelaces, and snagging on surrounding objects.

Known lock shoe laces (source [1]: patent RU 2177238), containing a housing and a clamp of laces with a button, the working part of which is located in the housing for fixing the laces to it, and part of the button is located behind the walls of the housing having holes, one of which made through for the passage of the laces, and the other - deaf for the release of the presser button, a compression spring located inside the case, one end of which rests against the presser, characterized in that it has a platform located in front of the hole for entering the laces, preventing the latch from tipping over when they are tensioned , while the back side of the lower part of the case is curved for a secure fit of the latch to the tongue, and the press button is curved, the upper part of which comes to the surface of the case when the laces are passed through it to enable the company logo to be applied to the surface of the case and the button

The latch [1] has an unreliable and bulky design, difficult to manufacture and impractical in operation. The use of a spring and a button to fix the laces does not provide the necessary force and the laces tend to move in the retainer when walking in shoes. The latch is unreliable since the internal cavities can become clogged with dirt and debris from the street, as a result of which the button jams, and the spring sometimes breaks. The retainer consists of several separate parts and requires special tools to install it.

Known lock laces (source [2]: patent RU 64033 U1), mainly for shoes, containing a body and a clamp of laces with a button, the working part of which is located in the body for fixing the laces to it, and part of the button in the recessed state is at the level of the end wall housing or is located behind the end wall of the housing, having holes made through for the passage of laces, and a blind hole for the release of the presser button and the movement of the press of the laces, made in the direction perpendicular to the direction of the axes of the through holes, as well as a compression spring located inside the housing. Two through holes for the passage of laces or parts of the lace are made two-stage of different diameters in the opposite walls of the case each, and the clamp is made of an elastic tape or wire bent to form between its two flat branches due to bulges in them two sockets with a diameter equal to the diameter of the smaller step a two-stage through hole, while in the body there is a pin clamp for clamp movement, the pin of which is passed between the branches of the elastic tape or wire in the zone of its inflection, the free ends of the branches of the elastic tape or wire are bent in opposite directions and inserted into the groove in the button, and the compression spring is installed enclosing an elastic tape or wire with support at the bottom of the button and the body.

The disadvantage of this latch is its fragility and insufficient reliability of fixing the lace. The latch [2] also has an unreliable and bulky design, difficult to manufacture and impractical in operation. The use of springs and a button to fix the laces does not provide the necessary force and the laces tend to move in the retainer when walking in shoes. The latch is unreliable since the internal cavities can become clogged with dirt and debris from the street, as a result of which the button jams, and the spring sometimes breaks. The retainer consists of several separate parts and requires special tools to install it.

Known latch for laces and shoes with such a latch (source [3]: patent RU 147287 U1). A shoelace retainer, characterized in that it comprises: a fastening plate and a hook in the form of an elongated body located essentially along said plate at a distance from it and configured to elastically bend in the direction from the plate and back; one of the ends of said hook is connected or made in one piece with said fastening plate, and the other end of said hook is free, while the distance between the free end of said hook and the plate in the unbent state is less than the smallest transverse dimension of the said laces, and in the bent state - enough to thread the laces into the space between the middle part of the hook and the plate.

The latch [3] does not securely fix the lace and does not provide a strong position of the tensioned ends of the lace when moving in the shoe. The geometric shape of the latch and the location of the lace on it does not allow the creation of friction forces that prevent the movement of the lace under heavy loads. The hook in the form of an elongated body, located along the plate at a distance from it, does not allow the lace to be given such a spatial configuration when it blocks itself due to friction forces. In fact, the latch [3] is not a latch capable of holding the lace in a taut state, it only provides fixation of the freely “dangling” ends of the lace.

The prior art lace retainer (source [4]: US 20160219984 A1). Shoe lace retainer [4] comprises a body made with four through holes and two recesses for laces. Two holes are designed to fix the middle part of the lace, the ends of the lace are fixed in the recesses. The recesses for the laces are made from the edge into the body of the latch. To fix the first end of the lace, the first recess is made, to fix the second end of the lace, the second recess is made.

However, the lace retainer [4] for shoes does not include lace end fixing holes for accommodating the ends of the lace. The body of the latch does not contain on its surface two grooves for laces, located between the holes, which are designed to fix the ends of the lace. The recesses do not allow fixing the ends of the laces using loops and have a low reliability of fixation, a tendency to spontaneous untying.

Known lock laces (source [5]: US 1806162 A1) made in the form of a body with four holes in the body from the edge deep into the slots for fixing the ends of the lace.

However, the latch [5] does not provide reliable fixation of the ends of the laces using loops and is inconvenient to use. The body of the latch does not contain on its surface two grooves for laces, located between the holes, which are designed to fix the ends of the lace. The recesses do not allow fixing the ends of the laces using loops and have a low reliability of fixation, a tendency to spontaneous untying.

Thus, the existing fixators have underdeliveries and require improvement. The present technical solution is aimed at improving the design of the shoelace retainer, increasing the reliability of fixing the laces, ensuring ease of use and ease of manufacture, while providing an aesthetic appearance and a minimum number of parts, without changing the design of the shoe and without the use of tools to use the device. Can be installed on any shoes with laces.

Description of work.

Shoe lace fastener is designed to fix laces on shoes. The lace is taken by the ends, stretched to the desired degree of tension, and the ends are passed into the through holes 2, 3, 6, 7 of the latch body. First, thread the two ends 5 and 9 of the lace from the bottom up into the central holes 2 and 6. Then thread the two ends 5 and 9 of the lace from the bottom up into the side holes 3 and 7. Lower the body 1 on the laces down until it touches the shoe. Wind the ends 5 and 9 of the laces around the body 1 so that they are located under the body 1. Thread the two ends 5 and 9 of the lace into two channels 10 between the side holes 3 and 7 under the parts of the lace 12 located on the body in the direction forward until the laces come into contact with the body. Due to the forces of friction and the geometry of the lace located in the holes 2, 3, 6, 7 and the channels 10, the body 1 prevents the ends 5 and 9 of the lace from moving freely. The parts of the lace 12 surround the ends 5 and 9 and do not allow them to move.
