Abstract

An anti-slip device intended to prevent footwear soles, vehicle wheels, crutches and walking sticks from slipping on ice, snow or other slippery material, thus preventing possible injury. The device comprises a movable stopper with feathered edges, said stopper being mounted in a cavity in a base (1) or between protuberances on the base (1) and being able to pivot about the point at which it is fastened when the feathered edges engage with a slippery surface until the stopper comes into contact with the walls of the cavity (4) in the base (1) or between protuberances on the base (1). The angle between the walls of the cavity (4) in the base (1) or between tangents thereto, between which the stopper is mounted, is 50-245°, preferably 90-160°. At each point along the axis of the cavity (4) in the base (1) or between protuberances on the base (1), the ratio of the distance between the nearest points on the inside surface of the cavity (4) and the maximum size of the stopper (2) in a plane across the face thereof is 2.6-1.2, preferably 2.0-1.4. The feathered edges of the stopper are situated at the same level as the surface of the base (1), which contacts with the slippery surface, or are situated close to this level inside or outside the cavity (4) in the base (1) or between protuberances on the base (1).

Description

ANTI-SLIDING DEVICE

Technical field

The invention relates to devices that prevent slipping of the soles of shoes, wheels of vehicles, crutches and canes on ice, snow or other slippery material, such as rock, moss, slippery algae, slippery pitfalls, etc., and preventing related injuries , and can be used in the shoe and automotive industries, as well as medical equipment. The device can also be used in cases of increased requirements for grip reliability, for example, with wet asphalt, non-standard speed modes, etc.

State of the art

Known anti-slip device for shoes, comprising a housing and working elements made in the form of a spike rigidly fixed to the housing and two single-arm levers attached to the housing with the possibility of rotation and connected to it using an annular spring. The spike and levers extend beyond the housing. The free ends of the levers are covered with rubber-like material, and their lower surface on a non-slip surface is located below the tip of the tenon. Cases with working elements are installed in the heel and the sole. On the slippery surface, the rubber ends of the levers slip, they rotate, and the spike penetrates the slippery surface, preventing the entire sole from slipping (RU 2400113 C1, MGZH (2006.01) A43C 15/14, 15/04, A43B 13/26, 21/36, Op. September 27, 2010).

A disadvantage of the known device is that the complexity of the design and the associated large dimensions, allowing Only install the device in thick soles. In addition, the disadvantage is that when walking on a non-slip surface, the shoes rest on levers located below the heel and the sole, which leads to an unstable position of the shoe when walking, as well as increasing the likelihood of damage to the device.

The disadvantage is the rigid vertical fastening of the tenon, which when walking on a slippery surface perpendicularly punctures it, while remaining stationary, forces the user to raise his foot with shoes also perpendicular to the surface to remove the tenon, which is inconvenient.

The closest analogue of the claimed device is an anti-slip device for shoes, containing a working body made in the form of a truncated ball, in the lower part of which there is a skirt with sharp edges. A movable spring-loaded rod with a tip made of anti-slip elastic material and protruding beyond the heel of the shoe is installed in the hole in the ball. The movement of the stem is limited by a pin. The ball is placed in a prefabricated cylindrical body with an internal spherical surface. In the upper part of the body there is a spring stabilizing the position of the ball. The device is installed in the hole in the heel and is attached to its inner surface. When walking on a non-slip surface, the stem with the protruding tip is recessed into the hole when it touches the surface, and when shoes slip on the surface, the stem deviates in the opposite direction, turning the ball, crashes into the surface with sharp edges of the skirt (RU 2471392 О, IPC (2006.01) A43C 15/14, op. 10.01.2013). The disadvantages of the known anti-slip device are the complexity of its design, functional unreliability and inefficiency, due to the fact that the tip of the stem does not always deviate to the side when the heel comes in contact with a slippery surface, but is recessed inside it, because the tip has a hemispherical shape and is made of anti-slip materials . This is explained by the fact that, as you know, the purpose of using anti-slip devices is to ensure that walking on a slippery surface is the same as on a non-slip one, that is, such a walk in which a person first puts the heel of the shoe on the surface, then the entire sole, after which the toe is repelled part and raises the leg, and does not slide all the time along the surface of the entire sole, without tearing off the legs from the surface. Thus, when using the known device, the user presses the heel on a slippery surface, and the tip does not turn, but simply recesses into the heel, and the sharp edges of the working body do not touch the slippery surface at all.

Also, the tip, speaking beyond the heel, constantly interferes with normal walking on non-slip surfaces. In addition, the complexity of the design of the known device determines its large size, which does not allow it to be installed in the forefoot or middle part of the sole of normal thickness, which also reduces the reliability and efficiency of the device.

And the installation of the working body (ball) in the casing with an internal spherical surface leads to the fact that with a possible rotation of the working body there is friction between it and the casing, which slows down and sometimes prevents this rotation. In addition, the gap between the body and the working body is quickly contaminated by snow, ice, dirt, etc., which leads to an increase in the mentioned friction, and cleaning this gap is difficult and requires disassembly of the device.

Another disadvantage is that the angle of possible rotation of the working body is limited by the body and spring and cannot exceed 45 °, which is insufficient for cutting sharp edges into a slippery surface, and this leads to a decrease in the sliding friction coefficient.

Another disadvantage is that the skirt with sharp edges during operation of the device is subject to wear and, due to its small size compared to the size of the body, can quickly completely wear out.

Disclosure of invention

The basis of the invention is the task of improving the anti-slip device, in which structural changes are achieved by increasing the coefficient of sliding friction when using the device on a slippery surface, the functional efficiency of the device and its reliability while simplifying the design, in the absence of obstruction of the device walking or other movement on a non-slip surface and increasing life, due to the easy rotation of the working body without friction with other elements and design and increase the angle of rotation, as well as the absence of a significant exit of the elements of the device beyond the base or protrusions on it when in contact with a non-slip surface, reducing the degree of contamination of the device and increasing the part of the stop in contact with a slippery surface, which can be worn without loss of functionality of the device . In the case of installing an anti-slip device on shoes, walking is also ensured. on a slippery surface is the same as on a non-slip surface, the ability to install the device both on the heel and on other parts of the sole.

The problem is solved in that in the anti-slip device containing at least one movable working body-stop with at least one level of sharp edges mounted on the contact side with a slippery surface, while the emphasis is at least in the lower part, tapering gradually towards the place of its installation at the base, and installed with the possibility of rotation when adhering sharp edges to a slippery surface, new is that the emphasis is installed in the cavity formed at the base or between blunts on the base, and is made to rotate around the place of its fastening until it contacts the cavity walls in the base or between the protrusions on the base, while the angle between the walls of the cavity in the base or tangent to them, between which the emphasis is installed, is 50-245 °, preferably 90-160 °, at each point along the axis of the cavity at the base or between the protrusions based on the ratio of the distance between the nearest points on the inner surface of the cavity and the largest size of the stop in the plane along its base is 2.6-1.2, preferably Tel'nykh 2,0-1, 4, and the sharp edges of the stop are arranged at the level of the substrate surface in contact with the slippery surface, or close to this level inside the cavity at the core or between the projections based on or outward.

The problem is also solved by the fact that the base is made whole or composed of at least two parts, for the connection of which the protrusions of one part are installed in the holes of the second part in contact with a slippery surface, while the stops are installed in the cavity or between the protrusions of the second part of the base and / or between the protrusions of the first and second parts of the base.

The problem is also solved by the fact that the emphasis is made solid, or solid with a hole for mounting, or hollow, or made together with the mount, or composed of several parts, which after assembly make up a single structure.

The problem is also solved by the fact that the emphasis is made in a shape similar to a cone or a truncated cone, or a pyramid with faces or without faces, or a truncated pyramid with faces or without faces, or part of a sphere, or a cylinder with a concave side surface in the middle, or a disk, connected to the top of the pyramid, or a disk with a skirt, or a sphere with a skirt, or combinations of these bodies.

The problem is also solved by the fact that the emphasis has an extended part with sharp edges on the side of contact with a slippery surface and / or an expanded part on the basis of the base to accommodate the fastening means and limit the angle of rotation of the emphasis.

The problem is also solved by the fact that the base of the abutment with sharp edges in contact with a slippery surface has the shape of a circle, or a triangle, or a square, or a rhombus, or a polygon, or a star, or a shape similar to these figures.

The problem is also solved by the fact that in the emphasis on the side of its sharp edges, slots are made, and the sections formed between them, which are spikes, are bent through one or in groups in and out.

The problem is also solved by the fact that the emphasis is fixed to the base made of a material having shock-absorbing properties, or a technological element is installed between the base and the stop and / or on the opposite side of the base in the form of a shock-absorbing washer, or spring, or the like. The problem is also solved by the fact that as the basis of the device used the sole of the shoe or the pad on the sole of the shoe, on the heel and / or forefoot of which the stops are installed.

The problem is also solved by the fact that as the basis of the device used the tire of the wheel of the vehicle or a removable pad on the tire of the wheel on which the stops are installed.

The problem is also solved by the fact that the stops are interconnected, for example by wire, cable, plate, chain or a combination of these means.

The problem is also solved by the fact that as the basis of the device used the tip of a crutch or cane or part of them in contact with a slippery surface on which the stops are mounted.

Between the totality of the essential features of the claimed invention and the achieved technical result there is the following causal relationship.

Constructive changes, namely:

- installation of the stop in the cavity formed in the base or between the protrusions on the base;

- the implementation of the emphasis with the possibility of rotation around the place of its attachment to contact with the walls of the cavity in the base or between the protrusions on the base;

- setting the angle between the walls of the cavity in the base or tangent to them, between which the emphasis is set equal to 50-245 °, preferably 90-160 °;

- the establishment at each point along the axis of the cavity at the base or between the protrusions based on the ratio of the distance between the nearest points on the inner surface of the cavity and the largest size of the stop in the plane along its base is 2.6-1.2, preferably 2.0-1.4;

- the location of the sharp edges of the stop at the level of the surface of the base in contact with a slippery surface, or close to this level inside the cavity in the base or between the protrusions on the base or out;

Together with the well-known features of the claimed invention, it provides sufficient space for the emphasis to rotate inside the cavity at the base or between the protrusions on the basis, the absence of constant direct contact and friction with other elements of the device, which makes it easy and unobstructed to rotate the emphasis when it engages with a slippery surface on angle up to 90 ° and the establishment of sharp edges in a close to perpendicular direction to this surface, and this leads to an increase in the degree of incision s edges in abutment slippery surface and thus increase the coefficient of sliding friction.

At the same time, the increased mobility of the stop, the possibility of its easy rotation do not need to significantly extend beyond the base or protrusions on it, the sharp edges of the movable stop easily catch on the slightest roughness of the snow or ice surface, which also increases the sliding friction coefficient, functional efficiency and reliability of the device. And the optimal size of the gap between the abutment and the walls of the cavity in the base or between the protrusions on the base provides the ability to easily and quickly clean the device from snow, dirt, etc., which also helps to increase the reliability and efficiency of the device.

In addition, the design of the claimed anti-slip the device provides an increase in its life, due to the significant allowable wear of the part of the stop in contact with slippery and non-slip surfaces, while maintaining the functionality of the device. This part can be half an emphasis or more due to the fact that the degree of possible wear is limited not only by the shape and strength of the emphasis, as in the closest analogue, but by the dimensions of the cavity in the base or protrusions on the basis between which it is installed and the size of which allows catching unevenness of the slippery surface and then turn to the braking position. When the emphasis is worn, due to the shape of its lower part, which gradually tapers towards the place of its installation at the base, its sharp edges are preserved, while being self-sharpening, and its functionality is preserved until, when slipping, it engages in irregularities of the slippery surface, turning in a braking position, and collide with the walls of the cavity or protrusions, abutting against them.

The establishment at each point along the axis of the cavity at the base or between the protrusions on the basis of the ratio of the distance between the nearest points on the inner surface of the cavity and the largest stop size in the plane along its base is more than 2.6 will result in even the largest stop size being small in comparison with the cavity, and this will not allow the emphasis during rotation to collide with the walls of the cavity at the base or between the protrusions on the base, as a result of which sharp edges will not cut into the slippery surface sufficiently, but will slip through calling, which will lead to a decrease in the coefficient of sliding friction, and the establishment of this ratio less than 1, 2 will not provide a sufficient angle of rotation of the stop, and as a result of a sufficient force of cutting into slippery surface, which also reduces the coefficient of sliding friction. At extreme values of the ratio of the distance between the nearest points on the inner surface of the cavity and the largest size of the stop in the plane along its base, the operability of the device is preserved, but it is not as effective as with the preferred values.

Setting the angle between the walls of the cavity at the base or tangent to them, between which the stop is installed, less than 50 ° does not provide enough space for the stop to turn, it rotates a small angle and weakly adheres to a slippery surface, and when this angle is set to more than 245 °, the emphasis is rotated too large an angle and also does not touch the slippery surface sufficiently.

In the case of installing an anti-slip device on shoes, it is possible to install the device on a heel, incl. on its back rounding, and on other parts of the sole, due to the simplified design of the device and its small dimensions associated with it, which ensures walking on a slippery surface the same as on non-slip, that is, walking such that a person first puts on the surface the heel of the shoe, then the entire sole, after which it is repelled by the toe part and raises the leg.

Thus, the technical result consists in increasing the coefficient of sliding friction when using the device on a slippery surface, the functional efficiency of the device and its reliability while simplifying the design and reducing the size, in the absence of the device preventing walking or other movement on a non-slip surface and with an increase in the period operation.

And the implementation of the slots in the part of the emphasis on the side of its sharp edges and the extension through one or in groups of inward and outwardly formed sections, which are spikes, makes it possible to create two rows of sharp edges, while the inner row of edges cuts into a slippery surface more easily and, accordingly, more efficiently puts emphasis in the working position, which also contributes to an increase in the coefficient of sliding friction.

Securing the stop in a base made of a material having shock-absorbing properties, or installing between the base and the stop or on the opposite side of the base of the technological element in the form of a shock-absorbing washer, or spring, or the like, allows the stop, due to the elastic properties corresponding to the weight of the user, to be sufficient crash into a slippery surface, which also provides an increase in the coefficient of sliding friction, and when in contact with a non-slip surface it is easier to move in the opposite direction and get sunk into the cavity at the base or between the protrusions on the base, which helps to reduce damage to these surfaces, eliminate unpleasant loud sounds, reduce wear of the stop.

The best embodiment of the invention

The anti-slip device (Fig. 1-19) comprises at least one movable working stop device 2 based on 1, with at least one level of sharp edges 3 on the contact side with a slippery surface, made with the possibility of rotation when sharp edges are engaged with this surface. The emphasis 2 is installed in the cavity 4 formed in the base 1, or between the protrusions on the base (not shown in the drawings) and is configured to rotate around its fixing point until it contacts the walls of the cavity 4 in the base 1 or between the protrusions on the base. The angle between the walls of the cavity 4 in the base 1 or tangent to them, between which the stop 2 is installed, is 50-245 °, preferably 90-160 °. If this angle is greater than 180 ° the sides of the cavity 4 are deepened into the base 1. The protrusions on the base 1 are located perpendicular or close to this position. The base 1 can be made integral or composed of at least two parts, for the connection of which the protrusions of one part are installed in the holes of the second part in contact with a slippery surface, while the stops are installed in the cavity or between the protrusions of the second part of the base and / or between the protrusions of the first and the second part of the base (not shown in the drawings). Such parts may be the sole of the shoe and the pad on it, the tire of the wheel of the vehicle and the pad on it.

At each point along the axis of the cavity 4 in the base 1 or between the protrusions based on the ratio of the distance between the nearest points on the inner surface of the cavity 4 and the largest size of the stop 2 in the plane along its base 5 is 2.6-1, 2, preferably 2.0- fourteen. The sharp edges 3 of the stop 2 are located at or close to the level of the surface of the base 1 in contact with the slippery surface inside the cavity 4 in the base 1 or between the protrusions on the base 1 or outward, that is, they can be slightly recessed into the base 1 or protrude slightly its limits (Fig. 5-13).

The emphasis 2 can be made integral, including with a hole for mounting the mount, it may have a slightly convex base 5 (not shown in the drawings), or hollow, or made with the mount, or consisting of several parts, which after assembly make up a single structure, for example, from the left and right, front and rear, upper and lower parts, the housing and parts with sharp edges, etc.

The stop 2, at least in the lower part, has a shape that gradually tapers towards the place of its installation at the base 1 and can be made in the form similar to a cone or a truncated cone (Fig. 1, 2), or a pyramid or a truncated pyramid, or a pyramid, incl. truncated, without edges (for example, a tripod), or a part of a sphere, or a cylinder with a concave lateral surface in the middle (Fig. 3), or a disk connected to the top of the pyramid, or a disk with a skirt, or a sphere with a skirt, or other shape, or combinations these bodies.

An emphasis in a shape similar to a pyramid disk is an emphasis in a shape similar to a pyramid fixedly attached to a wide washer, the edges of which are strongly rounded to protect the base from tearing. The disk and the pyramid can be connected and movably. The disk may be a regular washer, poured into a plastic shell. In this case, a disk-shaped form is optional, any other (from among acceptable) is possible. Technologically, this option is acceptable for implementation directly into the sole of the shoe (without removable pads) when the technological conditions for uniform wear of all components (emphasis, its fastening and sole) are achieved.

The emphasis in the form, similar to a disk with a skirt, is made cast. A disk of this form is suitable for work in the body of the sole (placed in a special cavity), the skirt protrudes slightly between the protrusions. When the emphasis is displaced, the disk deforms the sole material, which tends to straighten, so that the emphasis rotates to a free nominal position.

The emphasis 2 may have an expanded part with sharp edges 3 from the side of contact with a slippery surface and / or an expanded part from the side of the base 1 to accommodate the fastening means and limit the angle of rotation of the emphasis 2 (Fig. 3).

The base 5 of the stop 2 with sharp edges 3 in contact with a slippery surface may be in the shape of a circle (Fig. 5), or a triangle, or a square, or a rhombus, or a polygon, or a star, incl. with rounded corners, such as a six-pointed star (Fig. 7), or a shape similar to these figures.

In the part of the stop 2, on the side of its sharp edges 3, slots can be made to create two rows of sharp edges, and the sections formed between them, which are the spikes 6, are bent through one or inward and outward in groups (Fig. 4).

The emphasis 2 is made of durable wear-resistant material, for example steel, plastic, technical ceramics, etc., while it may have a special decorative or wear-resistant coating, as well as carbide inserts.

The emphasis 2 can be made by casting, stamping, powder metallurgy or mechanical method, or other. In this case, the fastening can be made together with the emphasis, preferably integral, or mounted already on the manufactured emphasis. To enable rotation of the emphasis when engaged with a slippery surface, the emphasis 2 can be fixed on the base 1 in various ways. Fixing the stop is possible with a lock washer or ring, as well as with an anchor method, welding, mainly spot, rivet, punch, screw, screw, screw, threaded rivet, hollow core rivet, rivet with spacer, etc. For example, the hollow stop can be fixed with a finger 9, installed with the extended end in the smaller hole 10 of the stop, and the other end into the sleeve 1 1, fixed in the base 1 (Fig. 5, 6).

The emphasis 2 can also be fixed using two joined fingers 12, one of which with the expanded end is installed in the smaller opening 10 of the emphasis, and the other in the first half of the sleeve 1 1 installed in the base 1, and the second extended end is installed in the opposite emphasis of the deepened surface of the base 1 and is fixed by the locking ring 13, and the other in the second half of the sleeve 1 1 (Fig. 7, 8).

The stop 2 can also be fixed with a screw 14, the head of which is installed in the smaller hole 10 of the stop, and the rod is screwed into the sleeve 1 1, fixed in the base 1, while a washer 15 is installed between the sleeve 11 and the stop 2 (Fig. 9, 10 )

Another option is to fix the stop 2 with the pin 9, installed with the extended end in the smaller hole 10 of the stop, and the other in the sleeve 16 in the base 1, and fixed by the washer 15 and the locking ring 13 (Fig. 1 1, 12). Moreover, the opposite is possible - the finger 9 is inverted by the retaining ring 13 into the stop.

A finger, rivet or screw can be installed in the emphasis 2 on the opposite side of the base 1, which does not come into contact with a slippery surface. In this case, the extended end of the finger, rivet or screw head should be wider than the smaller hole 10 of the stop, and the opposite end of the finger, rivet or screw may protrude somewhat beyond the base 5 of the stop with sharp edges, thereby forming an additional element for reliable engagement of the stop for a slippery surface for increase the likelihood of turning the stop to its working position

To increase the efficiency of pushing the stop into a slippery surface, the stop 2 can be fixed to the base 1 made of a material having shock-absorbing properties, for example, from a molded polymer product having a structure with elastic properties, or a technological element can be installed between the base 1 and the stop 2 in the form of a shock-absorbing washer 17, or springs, or the like. In this case, the washer can technologically be implemented as a lock washer (Fig. 13). In addition, the shock absorbing washer can be installed on the opposite side of the base 1.

Between the stop 2 and the base 1, a technological gasket can be installed in the form of a washer, the size of the area of which calculates the necessary degree of indentation of the stop into a slippery surface and into a cavity in contact with a non-slip surface. The smaller the area of the washer, the easier the stop enters the cavity, but less is pressed into the slippery surface. The installation of the washer allows you to prevent the possible coverage of the stop 2 by the base 1 from all sides, which can complicate the transition of the stop to the working position, helps to redistribute the load on the stop, protects the base from wear and possible tearing against the stop.

Inside the stop 2, through it and the base 1, a movable axis 18 can be installed (Fig. 14), which extends beyond the stop 2 for a short distance from the side of the slippery surface. Such an increased axis length forms an additional series of sharp edges that increase the likelihood of the stop moving to a working braking position. Axis 18, piercing the ice, rotates from a free position to an inclined one when slipping, forcing the edge of the stop to leave the base cavity and crash into ice, thereby providing resistance to slipping.

To increase operating efficiency, the axis 18 can be hidden inside the stop 2. This is achieved through the use of a shock-absorbing element made in the form of a flexible washer 19 (Fig. 15) or a spring 20 (Fig. 16), which can be located on either side of the base 1 or inside her, thereby providing tightness. The axis 18 with the shock absorber spring 20 can be performed integrally. The connection of the axis 18 with the cushioning washer 19 is carried out rigidly or movably by means of a thread, or a rivet, or a sleeve of a retaining structure, interchangeably or once. The elasticity of the shock-absorbing element provides a force sufficient for cutting the axis into ice, respectively, the area of the end face of the axis, in order to least affect non-slip surfaces, especially on floor coverings.

Part of the cavity of the base 1 between its walls and emphasis 2 can be filled with a soft elastic rubber-like substance, including porous, to prevent clogging of the cavity with large debris (stones, etc.) and to improve the rotation of the stop to the nominal position.

The proposed anti-slip device can be produced in a replaceable / repaired or disposable design. Depending on the purpose of the device, for example, for civil, work, sports, children's shoes, there are options for the size of the stop - small and large with an appropriate size fastener, while a number of sizes are possible.

An anti-slip device can be installed on the shoe, while the sole of the shoe or the pad 21 on the sole of the shoe can be used as the base 1, in which the stops 2 are installed in the cavity 4 on the heel part 22 and / or forefoot part 23 (Fig. 17-19) . At the same time, to maintain the tightness of the shoe, for example in rainy weather, the support of the stop can be technologically made together with the sole or pad 21, as an integral design.

The overlay on which the stops are mounted can be fixed to the sole of the shoe in this way. On the plate between the cavities with stops, through holes are made, which, by their location and protrusions of the tread of the sole correspond to dimensions. The mentioned protrusions of the sole are installed freely or with an interference fit in the holes of the patch, connecting the patch and the sole, it is also possible to use additional fixing elements. This increases the reliability of fixing the lining on the shoe. If necessary, a shoe kit can have several pads, and the pad can be divided during manufacture or by the user into the heel and toe parts, which can be used separately.

An anti-slip device can be mounted on the wheels of the vehicle, while the wheel tire or a removable cover on it can be used as the base 1, and the stops 2 are installed between the protrusions of the tire tread or the lining or on the protrusions of the tread themselves, for example, in bicycle or motor vehicles ( not shown in the drawings). The pad can be mounted on the tire in the same way as the pad on the sole of the shoe.

In this case, for synchronous operation, that is, rotation to the working position, the stops 2 can be interconnected by a thrust, for example, wire, cable, plate, chain, etc., or a combination of these means (not shown in the drawings). Traction is laid in the longitudinal groove formed between the tire treads. Traction is locked using a cotter pin, lock, hook, etc.

The connection of the stops with each other by a thrust helps to eliminate micro-slipping, that is, the displacement of the tire relative to the road when each stop is turned into a braking (working) position. To do this, it is necessary to turn each stop in a braking position before it collides with the road. Connecting the stops using torsional stiffness, such as flat connecting links, performing the role of rods, ensures that any emphasis that has turned into a braking position pulls the remaining stops at the same position. Thanks to the torsionally rigid connecting links from the plate, tube, rod, the tilt of all the stops synchronously becomes possible not only forward / backward along the chain when braking or slipping, but also to the right / left when side skidding. The emphasis in this case will be bent to abut against the wall of the longitudinal groove or seat. The connection of the stops with each other by the thrust is also necessary to return the stop to the neutral position, in order to avoid edge wear during normal normal rotation of the wheel. For reliability, it is appropriate to use a double or two-row connecting element (link). For example, an additional row of links can connect the stop side adjacent to the base, or can be made integrally with the base (poured into the base material), respectively, the main row of links controls the tilt of the stop and its return to the neutral position.

The anti-slip device can also be installed on crutches and canes, in which the basis for installing the stop are tips or parts in contact with a slippery surface (not shown in the drawings).

Anti-slip device operates as follows.

When walking, riding or other movement on a non-slip surface, the stops 2, the sharp edges 3 of which are located practically at the level of the surface of the base 1 or the protrusions on it, come into contact with the non-slip surface. The anti-slip device practically does not interfere with this movement in normal mode. When moving on a slippery surface (ice, snow, moss, slippery algae, slippery pitfall, wet asphalt, etc.), which cannot be perfectly smooth and which is affected by the pressure force of the weight of the user or the vehicle, sharp edges 3 stops 2, in any case, catch on irregularities of the slippery surface, at this time the base 5 of the stop continues to slip relative to the slippery surface and with further movement the stop 2 with the edges 3 rotates until it contacts the wall of the cavity 4 at the base or to limit backlash freewheel mounting, cutting into a slippery surface that provides a high coefficient of sliding friction and resistance and the no-slip shoes or wheels, or other products on the slippery surface. In this case, the shoe user can walk on a slippery surface as well as on a non-slip surface.

Snow, ice or other dirt may fall into the gap between the stop

2 and cavity 4 in the base or between the protrusions on the base, however, it is easily and quickly shaken out or removed from there.

During operation, wear of the base 5 of the stop and sharp edges 3 occurs, however, the shape of the stop provides the gradual formation of new sharp edges with the same gradual decrease in the diameter of the base 5, which allows the device to be used for a long time almost until the stop 2 is worn by 50%.

Thus, the claimed device provides an increase in the coefficient of sliding friction, functional efficiency and reliability of the device, simplifying the design, increasing the life of the device, and preventing the device from walking or other movement on non-slip surfaces.
