Anti-slip overshoe
View Patent ↗An overshoe that is removably disposable on a user's shoe and provides a tread surface that enhances the user's footing on slippery surfaces. The tread surface has removable spikes that penetrate surfaces and forward-oriented and rearwards-oriented gripping ridges that grip the surface. The ease of pulling on and removing the overshoe is enhanced by using stretch zones that are placed to allow stretching of the overshoe to fit over a shoe or the like without compromising the snugness of the overshoe fit. A spike assembly for use with an overshoe that fits over a person's shoe and enhances a person's contact with the ground, includes a spike having a head operably coupled to a shank; and a button overmolded on the spike and having a neck for removable engagement in a bore defined in the overshoe. A method of minimizing slippage on a ground surface is further included.
1. An anti-slip overshoe that fits over a shoe and enhances contact with the ground, the shoe having a forward toe portion, a rearward heel portion and a bottom for engaging the ground, the anti-slip overshoe comprising:
a single flexible elastic piece having a ball, a heel, a connecting portion, an over-toe component, and an over-heel component;
the ball and heel being connected by the connecting portion and each of the ball and heel having a tread pattern, the tread pattern having a plurality of gripping ridges and a plurality of spikes;
the over-toe component being operably coupled to the ball with a plurality of stretch zones so that the over-toe component conformingly engages the shoe toe portion, wherein the over-toe component has a plurality of apertures, one of which extends between each of the stretch zones, and wherein the plurality of stretch zones each have an approximately equal width; and
the over-heel component being operably coupled to the heel and being adapted to conformingly engage the shoe heel portion, the over-heel component having a plurality of apertures and having a plurality of stretch zones.
2. The overshoe of claim 1 wherein the plurality of apertures each have an approximately equal width.
3. The overshoe of claim 2 wherein wherein each of the plurality of apertures have a width that is greater than a width of each of the plurality of stretch zones.
4. The overshoe of claim 2 wherein the plurality of apertures comprises five apertures formed proximate the intersection of the ball and the over-toe component.
5. The overshoe of claim 1 wherein there are aperture formed the proximate the intersection of the ball and the over-toe component are disposed in a substantially semi-circular disposicion.
6. The overshoe of claim 1 wherein each of the spikes are removably disposed in a respective bore defined in the ball and heel and are secured therein so that they may be readily replaced by a user.
7. The overshoe of claim 1 wherein the over-toe component includes an over-toe body, the over-toe body having a plurality of apertures defined therein, a plurality of stretch zones being formed between adjacent over-toe body apertures.
8. The overshoe of claim 7 wherein at least thee of the over-toe body aperture are equiangularly, radially disposed relative to an origin of a semi-circle.
9. The overshoe of claim 7 wherein a circular over-toe body aperture is radially disposed relative to an origin of a semi-circle.
10. The overshoe of claim 1 wherein a first portion of the ball gripping ridges are angled in a first direction and disposed in a first chevron arrangement and a second portion of the ball gripping ridges are angled in an opposed second direction and disposed in a second chevron arrangement.
11. The overshoe of claim 1 wherein the ball gripping ridges are radially disposed relative to an origin of a circle in a pattern of concentric circles with increasing radii.
12. The overshoe of claim 11 wherein the gripping ridges are formed in continuous circles.
13. The overshoe of claim 11 wherein the gripping ridges are formed in circles selectively interrupted by spaces.
14. The overshoe of claim 13 wherein every other gripping ridge is selectively interrupted by spaces.
