Abstract

The invention can be used in light industry in the manufacture of shoes with anti-slip device. SUMMARY OF THE INVENTION: A shoe contains a sole, in the toe and heel part of which cavities are made to accommodate studs. The latter are fixed in pairs on the crankshafts. At their end are rigidly fixed pulleys. A cable tied to the drive cable is pulled over the pulleys. The latter is included in the mechanism for converting spikes from working to non-working position. An additional pulley is installed between the pulleys. The cable between one of the main and an additional pulley is set crosswise. 5 il.

Description

The invention relates to light industry, namely to devices that protect shoes from slipping.

Famous shoes with an anti-slip device by A.N. Novogrudsky, containing a sole, in the toe and heel part of which cavities are made to accommodate studs fixed in pairs on rollers mounted in loops fixed in respective cavities of the sole, the mechanism for converting studs a worker in a non-operating position, having a pedal switch, spring lock.

The disadvantage of this design is the possibility of its accidental self-exclusion from the working position to the non-working and self-switching from the non-working position to the working one.

The purpose of the invention is to increase the reliability of the device service.

The rollers of the switching mechanism, which have been pulled out from the inside of the shoe, are provided with tightly mounted pulleys, which can be turned in opposite directions by means of a cross-linking cable. The switching mechanism of the studs with spikes is made in the form of a bracket with a guide rod (pedal), to the ends of which are attached the ends of the drive cable, and the movement of the rod (pedal) is linear, facilitating switching.

The ends of the cable 10 are attached to a wire rope (pedal) 13 sliding along the straight line J5 in the holes of the guide 14 mounted on the bracket 15. From inside her side guide 14 fastened spring retainer 16, ball segment 17 which protrudes through 20 The relative krongateyne and hole in the hole in the guide. From the rear (inner) side, the ball is pressed with a retainer spring with a hole for the ball segment. The ball segment protruding from the on-25 side of the side takes up a position at one of the two sides of the base of the pedal 13, which has a cylindrical rounded protrusion 18, fixing the working and non-working position of the pedal. A layer of microporous rubber 19 with cutouts for holders 7 with spikes 8 is glued to the leather underlay 1. The thickness of the rubber sole surpasses the height of the spike holders when not in use. In the working position, the studs with spikes abut against the outer plane of the rubber sole 19. The front and rear holders with spikes are opposite to each other, and their movement through the cross drive with a cable occurs in opposite directions, which contributes to the stability of their positions when walking .AG i 45

The transfer of ips from the non-working position to the working position is carried out by moving the leg, cut off from the ground, backwards. At the same time, the projection of the pedal with the raised foot, resting against the projection of the pedal at the foot, transfers the spikes into the working position with the raised foot. Similarly, but moving the legs forward, the spikes are transferred from the working position to the non-working position.

This device with increased reliability insures the transition from winter slip, fraught with injury.
