Abstract

Usage: in the shoe industry in the manufacture of anti-skid means. SUMMARY OF THE INVENTION: The device comprises an L-shaped rod, the long end of which is mounted in the cavity of the heel, and a short end is made in the form of a handle, a spike and means for securing the long end of the L-shaped rod in the cavity of the heel. The spike is made removable in the form of an arc-shaped plate with an eccentric hole and a recess for connection with the L-shaped Rod. The long end of the L-shaped rod is threaded for connection with a locking element in the form of a threaded nut installed in the cavity of the heel. 4 hp f-ly, 5 Il.

Description

This invention relates to devices for preventing slipping of shoes.

A large number of anti-skidding devices are known. These include a device with removable folding heels, a device with sticky spikes, a device with spikes sticking into the sheath, a device with spring-loaded spikes on the elastic band, envelope heel.

Also known are devices with spikes retracting into the sole or heel. In this device, the spikes are mounted on a swivel rod. The degree without the possibility of dismantling is movably connected to the plate - the base, which, in turn, is poured into the thickness of the base. One end of the rod is bent in the shape of a handle for turning it.

The need to mount all the device in the thickness of the sole requires a significant refinement of the sole, weakens

the sole, the elasticity of which falls during the cold season. The tool cannot be dismantled, which prevents replacement of worn spikes. Cavities of the sole (or heel), through which the spikes exit, can be clogged with snow or dirt, which will prevent their quick removal to the non-working position. The device is quite cumbersome and difficult to manufacture. It is not suitable for installation on thin soles and on heels with a small cross-sectional area, it is less universal.

The aim of the invention is to improve ease of use by ensuring dismountable device.

This goal is achieved due to the fact that the spike is made removable in the form of a plate with a hole connected tightly to the sleeve through which the long end of the plate holding the H-shaped rod passes, and the means for fixing the end of the rod equipped with a thread

ABOUT

in the cavity of the heel, made in the form of a locking element, mainly in the form of a threaded nut installed in the cavity of the heel, for the purpose of installation in the working and non-working position, the spike is made in the form of an arc-shaped plate with a notch on one of the sides for interacting with the handle - short the end of the l-shaped rod, and the hole with the sleeve in the plate is made eccentric, in order to reduce the wear of the heel and fix the spike between the spike and the side surface of the heel, a vertical support plate shelf is installed in Ideal angle, horizontal shelf which is placed on the running surface of the heel, while on the vertical shelf of the support plate there is a hole coaxially with the spike hole through which the spike sleeve passes and the spike is installed on the outside of the heel.

Figure 1 shows a heel section in a vertical plane with a device in the working position, the spikes are turned teeth down; figure 2 - cross section of the heel in a horizontal plane with a device in the working position; on fig.Z - heel with a spike in the working position, side view; figure 4 - the same, in the off position; Figure 5 shows a section of the heel in a vertical plane with a retracted fixture and a hole in the heel plugged with decorative traffic jams (the solid line shows the secret nut-fuck, poured into the heel during factory shoe preparation, and the dotted line shows the nut when home shoe preparation).

The anti-skidding device mounted on the outside of the heel contains a plate spike c4 sleeve 1, a support plate 2 folded under the heel, an L-shaped rod 3 for fastening and turning the spike, and a countersunk nut 4 embedded in the heel. A handle extends through a recess on one of the sides of the arcuate spike — the short end of the L-shaped rod for turning the spike into its working and non-working position. The lower part of the support plate 2 is bent under the heel in the form of a foot-rest. The spike hub, passing through the hole in the support plate, does not allow the spike to rise in a soft heel when pressing on a hard crust, does not break the hole in the heel, keeps the spike in an upright position. An eccentrically secured sleeve in the spike plate allows the spike tooth to expose the spike tooth beyond the heel plane (Figures 1 and 3) or turn the spike tooth upwards (Figure 4) when it is rotated 180 °. The operation of this device showed that setting the teeth of the spike above the plane of the sole of the heel 3-4 mm holds the shoes well on slippery surface and does not create any nudity when walking. AT

If the need for fixing is no longer necessary, the spiked rod turns out of the futorka and with the base plate is removed from the hole in the heel. A decorative cork is inserted into the hole of the heel (Figure 5). Installation of the device is available to people of any age, which is important for the elderly.

A serious fight against winter injuries should start with the release of the entire winter

5 shoes prepared in advance for the installation of the proposed fixture, and the fixture should be an obligatory attachment to each pair of winter shoes. The device must sell in and in shoe stores separately. It is possible to drill a hole in the heel both at home and in a shoe shop.

Claims (5)

Invention Formula 51. A device for preventing slipping of shoes for mounting on a heel, comprising a spike connected to an L-shaped rod, the long end of which is installed in the cavity of the heel, and the short end is made in the form of a handle, and means for securing the long end of the L-shaped rod to heel cavity, characterized in that, in order to increase ease of use by providing neither disassembling of the device, the spike is made removable in the form of a plate with teeth placed on one of its faces and a hole for connection with an L-shaped rod , The long end of which is threaded, 0 and the means for securing the long end of the L-shaped rod in the cavity of the heel is made in the form of a fixing element mainly in the form of a nut installed in the cavity of the heel. five 2.
