Description

(54) HEEL

J.

The invention relates to the shoe industry.

A heel is known that contains a means, anti-slip shoes, which consists of a movable support element in the form of spikes, a lock element of the support element and a mechanism for its extension fixed on the axis, which is led out onto the outer surface of the heel 1.

A disadvantage of the known heel is the inconvenience of use due to the fact that the retainer does not reliably secure the support element, which does not adhere to the surface of the ice. while walking.

The aim of the invention is to improve the usability.

To achieve the goal in a heel containing; located in the cavity of the heel means for preserving; slip-on shoes, including a fixed support element, with rod and outer parts, a lock of the support element in the working and non-working position and its extension mechanism, the lock is made in the form of a closed permanent magnet, located on the rod part of the support element, and the outer part of the latter is made in the form of a plate with teeth.

FIG. Figure 1 shows a heel containing a means for protecting shoes from slipping located in its cavity; in fig. 2 and 3 - section A-A in FIG. 1 (working and non-working position, respectively).

The heel 1, containing a means for protecting the shoes from slipping located in the cavity of the heel, consists of a support of an element 2, with an outer one, made in the form of a plate with teeth 3, and a rod

15 with a part made, for example, in the form of a sleeve, from a closed permanent magnet 4,

 located on the core part of the support element I, and from the extension mechanism of the support element consisting of an eccentric 5, with an axis that supports the supports 6, located in the channel 7 of the heel 1. On the side surface of the heel 1 to the axis with the eccentric 5 is attached a rotary lever 8. The upper end of the support element 2 abuts the eccentric .5.

In the off position, the plate with teeth 3 is located inside the cavity of the heel 1. The device is brought to the working position by turning the lever 8 on the side surface of the heel, which ensures the extension of the support element 2. It is fixed in a predetermined position by a permanent magnet 4.

Before entering the room, turning the lever 8 and the eccentric 5 releases the support of the core part of the support element 2 and under the action of pressure while supporting the heel during the walking, the support element 2 is retracted into the vertical groove of the heel 3 and held there by the magnet 4.

The proposed heel design improves usability, is more hygienic in operation, and provides driving safety during icy conditions.
