Description

The utility model relates to the shoe industry, and in particular to devices for protecting shoes from slipping.

A known construction of a removable patch sole (French patent 2519240, class AB 13/36, 1983), in which the fixing means, is made on the running surface of the main sole of the shoe in the form of a double-sided adhesive tape. The disadvantage of this design is that when wearing shoes without a false sole, the adhesive tape wears out quickly.

Another well-known technical solution (AS USSR N 991995, class AB43B 13/22, 1983) is a sole that protects shoes from slipping and has abrasive particles fixed with glue on its running surface, and glue with abrasive particles is applied in the form of strips, horizontally located in the heel and toe sections.

The disadvantage of this sole is a short shelf life of anti-slip properties, caused by poor adhesion of the adhesive to the elastic running surface of the sole, subjected to periodic bending.

Known removable sole (RU No. 2064771, 1992, АВВ 13/36, prototype), containing a sole with buttons embedded in the base of the sole and a frame strip with external and internal Velcro, buttons on the heel of the heel, a zipper of the leather upper. A removable sole is put on the sole of the main shoe, fixed with buttons installed coaxially in the grooves of the main and removable soles, additionally secured with buttons on the heel of the heel, as well as external and internal Velcro on the frame strip of the main and removable soles. It is possible to connect the top of a removable sole, which is made to the size of the main one, through a zipper.

The disadvantage of this removable sole is the narrow functionality, because it can only be used with shoes that have response buttons; it has great difficulty in manufacturing and use, since putting on a removable sole on the main one involves getting into the response buttons.

The closest analogue is a device for protecting shoes from slipping (patent RU 45906 U, publ.: 10.06.2005.), Containing a sole, while the sole is made in the shape of a heel and contains spikes pressed into the sole, and to the lateral parts of its outer side attached fastening strips with locking elements for fixing in the area of lifting the feet and a locking tensioning device for fixing in the area of the heel.

The prototype has versatility for any shoe.

The technical problem of the prototype is that the usual manufacture of the sole from a rubberized material, leather or plastic with spikes does not allow effective protection against slipping. The spikes, despite the fact that they are pressed into the sole, do not cut into the ice well enough, since the device does not allow you to adjust the tension of the strips and their tight fixation to the foot in the heel area. As a result, the latch in the heel area does not provide sufficient tension, causing a dangling state, which during movement reduces the effectiveness of the slip protection by the fact that the device is not tightly fixed on the foot, the pressure of the foot on the heel is not firm enough.

In addition, the use of spikes pressed into the sole provides inconvenience when walking with a hard stop in the heel.

The objective of the utility model is to eliminate the disadvantages of the prototype.

The technical result of the utility model is a deeper penetration of the spikes into the ice.

The specified technical result is achieved due to the fact that the claimed device for protecting shoes from slipping, containing the sole, while the sole is made in the form of a heel and contains spikes pressed into the sole, and fastening strips with fixing elements for fixing are attached to the sides of its outer side in the area of lifting the feet and a locking tensioning device for fixing in the heel, characterized in that the spikes are metal spikes with solid inserts at the ends, where the material of the studs has a hardness less than the material of the hardness of the insert, and the base of the studs located in the zone pressed into the sole has a broadening of a larger diameter than the diameter of the stud, the inserts protruding in height relative to the end of the studs and have a diameter smaller than the diameter the tenon into which they are pressed to a depth not reaching the broadening of the base of the tenons; annular protrusions are located around the spikes, smaller in height than the spikes in height, grooves are made inside the annular protrusions along their inner perimeter and extend to the surface of the spike, and an annular groove is formed around the spike.

Preferably, as the spikes, metal spikes are used with solid-state winding inserts at the ends.

Preferably, the latch tensioner for fixation in the heel region is made up of two fastening strips located on the sides of the outside of the sole and having locking elements, wherein the fixing strips with locking elements for fixing in the heel region have holes and removable fixing means passing through the holes both bands when overlapping each other.

Preferably, the protrusions located around the spikes are made of the same material as the sole, and form a whole with it.

Preferably, the fixing strips for fixing in the heel region are made of the same material as the sole and form a single unit with it.

Preferably, the sole further comprises corrugations. Brief Description of the Drawings

Utility Model Implementation

A device for preventing shoes from slipping (see Fig. 1) contains a sole 1, while the sole is made in the form of a heel and contains spikes 6 pressed into the sole, and fastening strips with fixing elements 3 are attached to the side parts 2 of its outer side for fixing in the area of the lifting of the foot and a locking tensioning device for fixing in the heel.

New is that the locking tensioning device for fixing in the heel is made up of two fastening strips 4 located on the sides of the outside of the sole 1 and having locking elements 13 (see Fig. 4).

It is conceivable that the sole 1 further comprises corrugations 5 that increase grip on the ice, prevent slipping and provide softness when stepping on the heel while walking.

A locking tensioning device for fixing in the heel region, which consists of two fixing strips 4 located on the sides of the outer side of the sole 1 and having locking elements 13, provides an adjustable completeness of the tension of the heel. This allows you to provide pressure on the heel firmly enough without hanging out, which improves adhesion to ice.

Strong adhesion to the heel of the device provides a softening of pressure on the heel, since the heel does not experience shock loads when the inside of the sole contacts the shoe when it does not hang.

Moreover, as the spikes 6, metal spikes with solid-state inserts 7 of greater hardness at the ends are used. The base of the studs located in the zone pressed into the sole 1 (see Fig. 2) has a broadening 10 of a larger diameter than the diameter of the stud 6. This does not allow the stud 6 to fall out of the sole during operation of the device, since with inserts 7 that easily cut into the ice, without broadening 10 spikes can easily pull out of the sole and remain in the ice. For this reason, the presence of broadening is a need in which the device according to the claimed utility model will remain operational.

The inserts 7 protrude in height relative to the edge of the end of the studs 6 and have a diameter smaller than the diameter of the stud in which they are pressed to a depth not reaching the broadening 10 of the base of the studs. This is important for the purpose that the inserts 7, which are made of material more hard than the spikes, for example, of Pobedit, do not penetrate the widened base of the spike and do not go into the soft sole during loading.

Due to the fact that metal spikes with solid-state inserts of greater hardness at the ends (for example, inserts are victorious and steel spikes) are used as spikes, the base of the spikes located in the zone pressed into the sole has a broadening of a larger diameter than the diameter of the tenon, and the inserts protrude in height relative to the edge of the end of the tenons and have a diameter smaller than the diameter of the tenon into which they are pressed to a depth that does not reach the broadening of the base of the tenons, the tenons are less erased and bite into ice much better, providing Vai better adhesion. Due to the greater hardness of the inserts, in comparison with the hardness of the material of the studs, they can be made thinner than the diameter of the studs and pressed inside them. In this case, the thin and hard ends of the inserts under the weight of a person cut into the ice much better than the thick flattened spikes, which improves the adhesion to ice.

At the same time, due to a softer and more easily pushing ice with thinner inserts, pressure on the heel is softened, since first the load of pressure on the heel takes the force of the inserts to enter the ice, and only then the flattened ends of the tenons abut the ice.

Around the studs 6 are annular protrusions 8, smaller in height than the spikes, inside the annular protrusions along their inner perimeter grooves 12 are made extending to the surface of the stud 6, and an annular groove 11 is formed around the stud (see Fig. 3). The grooves 12 can be formed, for example, in the form of gaps between the radially arranged segmental sections 9, which form inside the annular protrusion 8.

Due to the fact that annular protrusions 8 are located around the spikes, smaller in height than the spikes 6 height, grooves 12 are made inside the annular protrusions along their inner perimeter and extend to the surface of the spike, and an annular groove 11 is formed around the spike at the moment of pressing the heel of the spike insert bite into the ice, while the soft material of the sole is pressed through by the widened base of the spikes located inside the sole, dragging inward the material from which the annular protrusions formed around the spikes are formed. This material of the annular protrusions is compressed along the grooves towards the annular groove, forming a truncated cone, which with its top rests on ice 15 and softens the pressure on the heel (see Fig. 6).

In addition, at the moment of piercing the ice with the insert, the spike abuts against ice, and also the edge of the compressed annular protrusion abuts against ice, covering the spike along the perimeter, preventing the flattened end of the spike from sliding on the ice surface, which improves adhesion to ice (see Fig. 6).

Fixing strips 4 with fixing elements for fixing in the heel region may have various fixing means. For example, they can have openings 14 and removable fixation means 13 passing through the openings of both strips when superimposed on each other (see Fig. 3).

The annular protrusions 8 located around the spikes 6 can be made of the same material as the sole, and form a single whole with it. For example, they can be created in the process of molding rubber or by molding in the manufacture of plastic products. Similarly, the fixing strips 4 for fixing in the heel region can be made of the same material as the sole, and form a single whole with it.

All of the above circumstances, the influence of the distinctive features of the utility model as a whole, together provide improved adhesion to ice and softness when stepping on the heel when walking.
