RU2293504C2 - Antiskid device for shoes - Google Patents

Abstract

FIELD: light industry, in particular, equipment for preventing shoes from skidding.

SUBSTANCE: antiskid device for shoes has pins and handle for moving to operating and inoperating positions. Antiskid device comprises three steel thin rods having bent portion-pin at their ends, said pins being adapted for rotation through 180 deg on sole. Antiskid device comprises member for moving to operating and inoperating positions, said member consisting of conical gears rigidly fixed on rods within heels, and handle for moving antiskid device to operating and inoperating positions, said handle being adapted for rotation through 180 deg on heel rounded part.

EFFECT: convenient usage and increased safety during walking on icy surface.

Description

The invention relates to light industry.

As a prototype taken anti-slip, containing a base plate for attachment to the edge of the sole and heel, spikes equipped with a handle and mounted on the base plate with the ability to rotate 180 ° and fixation in working and non-working positions. RF patent №2020842, 1989

Its disadvantage: six spikes on a pair of shoes are translated into working and non-working positions individually, which takes time.

The aim of the invention is to eliminate the disadvantage inherent in the analogue.

The specified goal is achieved by the following constructive solution.

The antiskid for shoes contains spikes and a handle for translating into working and non-working positions, three thin steel rods with a bend - a spike at the end, mounted with 180 ° rotation on the sole, and a device for translating into working and non-working positions, consisting of rigidly fixed on the rods of the bevel gears located inside the heel, and the handle for translating the anti-slip into the working and non-working position, installed with the possibility of rotation by 180 ° on the heel rounding.

The invention is illustrated by drawings.

Figure 1 shows: a sole with recesses for installing anti-slip parts, an external view, a heel with holes and a cavity for installing anti-slip parts, a longitudinal section, side view; figure 2 shows the anti-slip assembly mounted on the shoe; on figa schematically shows the sole and heel with anti-slip, longitudinal section, side view; sole with spikes, cross section, heel rounding with a handle, outside view; inoperative position of the anti-slip; on figb - the same working position.

The sole 1 (figure 1) is made with grooves 2 and recesses 3. The heel is made with a hole 4 and a cavity 5.

In the grooves of the sole 1 (Fig. 2), the rods 6 are mounted with a bend-stud 7. In the recesses of the heel the plates 8 are made fixed with glue, made with two extruded brackets, a bracket 9 for the rod and a bracket 10 for the stud in the idle position . The plates are designed for fastening rods with spikes on the sole and preventing them from being pressed into the sole, which will reduce or completely eliminate anti-skid.

The device for translating the anti-slip into working and inoperative positions is reduced for convenience: turning on and off is made in the form of bevel gears 11 rigidly attached to the rods 6, mounted in the cavity inside the heel, and the handle 12, rigidly fixed to the end of the center rod. The gear of the Central rod is made with two stops 13, spring-loaded leaf spring. The handle 12 is made with teeth offset from the hole for mounting on the rod, and is placed on the heel of the heel. Pin 15 is rigidly fixed on the heel of the heel. The spikes 7 can be pointed, but not necessary, because the rods are thin and can prevent slipping without sharpening. The steel rods are thin so as not to impede the bending of the sole when walking. The plate 15 prevents the radial displacement of the gears 11, providing a constant engagement of their teeth.

Anti-slip for shoes works as follows.

To transfer the anti-slip from the inoperative position (Fig. 3a) to the working position, the handle 12 is rotated 180 °. In the operating position of the anti-skid (fig.3b), the spikes 7 protrude above the surface of the sole, and the teeth of the handle - above the heel rounding of the heel, preventing the shoes from slipping into ice.

The anti-slip is fixed in the working position due to the displacement of the handle teeth relative to the mounting hole. The load on the teeth presses the handle 12 to the pin 15, preventing the rotation of the handle and thereby turning off the anti-slip. In working and non-working positions, the handle is held by the spring-loaded stops 13 of the central gear 11 (figure 2).

Claims (1)

Antiskid for shoes, containing spikes and a handle for translating into working and non-working positions, characterized in that it contains three thin steel rods with a bend - spike at the end, mounted with 180 ° rotation on the sole, and a device for translating into working and non-working a position consisting of bevel gears rigidly fixed to the rods located inside the heel and a handle for translating the anti-slip into working and inoperative positions, mounted with the ability to rotate 180 ° on the heel round nii.
