Description

The utility model relates to devices and accessories worn on winter shoes for the safe movement of pedestrians during periods of ice and the snow cover of roads and sidewalks.

A device for protection against slipping, containing spikes in the form of links from a wire of a chain circuit made of mutually perpendicular oval-shaped links and equipped with loop clips of elastic bands designed to cover the toe and back of the shoe (DE No. 19522959, A43C 15/10, 1997).

This device is universal for shoes of various sizes, however, the chain contour, which is placed completely on the sole, is rigidly attached to the latch, which is firmly held only on shoes with a welt. This disadvantage limits the range of use, as it reduces the functional reliability of the device, if there is no such limiter for the latch on the shoe, and then it is held only by frictional tension forces of elastic bands.

Another disadvantage of this device is the lack of tension of the circuit circuit on the surface of the sole, which consequently freely sags, which can cause a fall

pedestrian with possible hooks for bumps, protrusions, objects, etc. mechanical obstacles to roads and sidewalks. In addition, this drawback is compounded by the inevitable slipping of the sole relative to the chain contour, sufficient to lose the balance and stability of the pedestrian, especially on ice and slippery hardened soil.

Also known is a device for protecting shoes from slipping "WINTER HORSESHOE" (RF patent No. 42400, MPK7, А43С 15/10, 12/10/2004), selected as a prototype of the claimed utility model. This device is made in the form of a flat figured plate of elastic material containing at the same time the whole toe, heel and middle parts, and the toe and heel parts are made in the form of loop clips to cover the toe and heel parts of the shoe, and the middle part is made in the form of a plate with fixed in it there are spikes, the tips of which face the outer surface, and the opposite ends are made flat flush with the inner surface of the plate. To increase reliability and prevent displacement of the middle device relative to the sole of the shoe, corrugation is performed on its inner surface. To facilitate removal of the device from the shoe on the end of the loop of the heel of the heel part from the outside is made tongue. To facilitate putting on the toe loop hinge on the toe of the shoe, it is made in the form of an oval, the large axis of which is perpendicular to the longitudinal axis of the device. To increase grip on the outside

devices with soil (ice) on the outer surface of the plate with spikes made at least two arched protrusions in the shape of a horseshoe.

The proposed device in comparison with the analogue significantly increases the reliability of its work, due to the use of spikes instead of chain links, and the convenience of using it, especially when removing this device from shoes, thanks to the tongue.

However, the practice of using currently marketed devices manufactured according to RF patent No. 4200 and RF patent No. 846420 indicates that the aforementioned devices have a significant disadvantage in that when they are used in difficult winter conditions, for example, periods of deep snow cover, snow drifts and especially when freezing the snow surface with the formation of an ice crust on it, i.e. in situations of frequent fluctuations in weather conditions with thawing and freezing of the snow cover, the toe loop latch when walking can jump off the toe of the shoe, regardless of its model. In this case, the device is simply lost in the snow. This situation more often occurs in children, but in adults, such cases are also not uncommon.

The technical result, the achievement of which the claimed device is directed, is to prevent the possibility of the toe loop loosening off the shoe toe and losing the device in the snow in various weather situations, when it is difficult

constantly monitor that the devices on the left and / or on the right leg are still in place.

The aforementioned technical result is achieved by changing the structural form of the loop fastener of the forefoot by supplementing it with a locking loop fastener, similar in shape to the heel loop fastener adjacent to the middle part of the device.

The inventive utility model of a device for protecting shoes from slipping is illustrated by drawings, where:

FIG. 1 - general view of the device, bottom view;

FIG. 2 - general view of the device, view from the side of the sole;

FIG. 3 is a section AA in FIG. one;

FIG. 4 is a photograph of a woman’s boot with the inventive device for protecting shoes from slipping “CASTLE” on it, a general view.

The device for protecting shoes from slipping is a flat figured plate made of elastic material, containing at the same time a whole heel (heel loop latch) 1, middle 2, forefoot (toe loop latch) 3 and a lock (lock loop latch) 4 parts. The middle part 2, having a corrugation 5 on the inner surface, is made in the form of a plate with spikes 6 fixed on it, the tips of which face the outer surface, and the opposite

the ends of the studs are flat flush with the inner surface of the plate. On the outer surface of the middle part 2 of the figured plate, two arched protrusions 7 in the shape of a horseshoe are made, which serve to increase the adhesion of the outer surface of the device to the ground (ice). The heel loop lock 1 is provided with a tongue 8.

The sequence of putting the device on shoes previously worn on the feet. Take the device with the fingers of both hands, orient it in front of the toe of the shoe as it is shown in FIG. 1, i.e. with the spikes turned upside down, so that the loop hinge is in front of the toe of the shoe 4. Insert the shoe to the inside of the loop of the lock of the hook 4 and pull the toe loop of the hook 3 on the toe of the shoe, stretching the fingers slightly with both fingers to securely pull it on the toe shoes. Then, using the tongue, pull the lock loop fastener 4 higher on the shoe back, release it and go to the heel loop clamp 1. Pull it, using the tongue 8, on the shoe back to the optimal position and release. Then, having pulled the lock loop fastener 4 toward you, lower it until it overlaps with the heel loop lock 1.
