Description

The invention relates to shoes and can be used both in civilian samples of shoes, and in the military in order to facilitate and accelerate the process of shoeing.

In the prior art patent RU 148740, which describes the device for shoe shine, in which the lace is done using a system including an electric motor, chips, controllers. Moreover, the signal for pinching can go both by wire and by air.

Differences from the stated solution are that:

- Shoes with a system of self-tightening laces do not have electrical mechanisms, and, accordingly, the power sources of these mechanisms, which eliminates the need to replace batteries or charge batteries;

- Shoes with a system of self-tightening laces actuates the mechanism in direct contact with the human foot, without the use of communication.

Known patent US 2016219985, describing the lace-up system using electronic and mechanical components.

Differences from the stated solution are that:

- Shoes with a system of self-tightening laces do not have electrical mechanisms, and, accordingly, the power sources of these mechanisms, which eliminates the need to replace batteries or charge batteries;

- Shoes with a system of self-tightening laces have a simpler pattern of execution.

The closest solution is the patent US 7096559, which describes the mechanical system of tightening the laces. Moreover, the pull-ups of the laces are made at their ends and the tension force of the lace may be different in different places of attachment to the shoe.

Differences from the stated solution are that:

- Shoes with a system of self-tightening laces have several individual laces that are pulled evenly with the necessary effort;

- Shoes with a system of self-tightening laces have a hydraulic drive mechanism;

- Shoes with a system of self-tightening laces are automatically activated when the person first steps on the leg she is wearing.

The technical result of the claimed invention is to simplify the process of shoeing and the subsequent removal of the shoe from the foot and create a system for tightening the laces, capable of operating automatically without the use of power sources and, if necessary, having a tension control system.

The technical result is achieved by positioning in the sole of the footwear of the hydraulic system, which activates the mechanism when a person puts on shoes and transfers weight to the foot or takes the first step with the shoe.

Special cases of manufacturing shoes with a system of self-tightening laces are:

- The location of the elements of the system outside the shoe or closed inside the walls of the shoe;

- The use of a system for regulating the tension of laces or the lack thereof;

- The main and tightening parts of laces can be combined and represent one element;

- The use of the system in everyday, sports, special and other shoes.

On images of shoes with a system of self-tightening laces, the following elements are indicated:

1. The upper part of the shoe;

2. Sole;

3. The main part of the laces;

4. Tightening part of the laces;

5. Tension regulator;

6. Tension element (spring, rubber insert, etc.);

7. Holes for connecting the laces with the mechanism;

8. Podyatochny reservoir;

9. Hydraulic tube;

10. The piston;

11. Spring lock (tension spring);

12. The lock;

13. Piston spring (compression spring);

14. Drive blocker;

15. Loop.

Shoes with a system of self-adjusting laces are operated as follows:

Initially, the system is at rest and when a person puts shoes on his foot, the system continues to maintain this state. But as soon as the person has put his foot (with shod shoes) on the surface, it remains only to exert some effort on the heel pad (8). To do this, you need to stand up (if the person was sitting) or simply transfer the load of the foot to the heel.

The heel-tank (8) under pressure is slightly dusted and the liquid goes through the tube (9) to the pistons (10) which have small grooves. The pistons (10) under pressure move up to the actuation of the blocker (12) which is actuated by the spring (11) and locks the pistons, being fixed in their grooves.

And when the pistons (10) move, they tighten the string (4) connected to them through the holes (7). The lace (4), in turn, tightens the main lace (3), thereby securely securing the human foot inside the shoe.

In addition, they are not mandatory and may be absent, but a tension element (6) and a tension regulator (5) are possible in the application. The possibility of their presence is due to the fact that, despite the same shoe size, different people may often have a situation when the type of foot is different, and therefore the convenience of wearing the same shoe among different people is different. So, for one person, the tension of the laces may be too strong, and for another insufficient. Tension regulator (5) is designed to tighten and loosen laces. It is assumed that, in the manufacture of shoes, it will be inside the sole (2) or inside the sidewall of the upper part (1). On the images it is indicated schematically. It is also assumed that the tension regulator (5) will be used an extremely small number of times when using shoes (for example, adjustment will be made during first wear and when transferring used shoes to another person) and in budget versions of shoes it may not be practical. The stretching element (6) is a cheaper option, although its stretching may be insufficient, and the structure of the material may change over time. Moreover, as an extension element (6), an insert from a spring block, a rubber cord and other materials with similar properties can be used.

In addition, the tension regulator (5) and the tension element (6) can be used on the same footwear together.

When walking, the shoes are securely fixed on the foot with the help of a blocker (12) which prevents the pistons (10) from returning to their original position and loosen the laces (4), which can lead to a fall of the shoes from the foot.

In order to remove shoes from a person’s feet, it is necessary to reduce the load on the heel pad (8) by lifting the legs and pull the loop (15), which is connected to the stopper (12) using a special drive (14).

In this case, the blocker (12) is pulled back freeing the pistons (10), which by means of the springs (13) return to their original position and weaken the laces (4). When this fluid through the tube (9) is returned to the heel cushion (8).

After a person has pulled a loop (15), he can take off his shoes from his feet, since the mechanism will work automatically and quickly enough.

Features of the invention:

1. Since the heel cushion (8) must be slightly flushed under the person’s foot to trigger the system, it is assumed that it will have a slightly convex shape so that when the person’s leg is up, the person’s leg will return to normal and not feel any discomfort.

2. For better perception of images, some elements on them are shown on the outside of the shoe, but it should be assumed that in the production of shoes, these elements should be removed inside the sidewalls of the shoes or inside the sole. For example, the laces (4) spoil the appearance and increase the danger of being caught on an obstacle if they are outside. However, the external execution of the system is also possible depending on the design of the structure.

3. Some shoe samples may not have a loop (15). But it should be noted that it is not a critically necessary element. The drive of the blocker (14) or the blocker itself (12) can be connected with a button, a lever, a boot tongue.

And besides, the lock can be rotating. In this case, the tension spring (11) is replaced by a torsion spring, and the lock is shaped as a circle cut off on one side. And thus, the side where the circle is kept can enter the grooves on the pistons (10) and block them, and if the blocker turns to the other side (where the circle is cut), then the piston can move freely. In this case, the most suitable option for unlocking is the button hidden in the sole.

4. Different laces (4) can be combined into one and be connected to one single piston (10) and also have one common tension regulator (5) and a stretching element (6).
