Abstract
To prevent people from slipping on ice and other slippery surfaces, devices have been designed to achieve this purpose. In this invention, the device which will be attached to a footwear consists of a sole with multiple conical spikes extending downward from the bottom surface and with strips of metal attached along with the spikes. The edges of the metal strips are bent downward and are provided with narrow ends for traction on slippery surfaces. The sole is also provided with clips on its sides for gripping the sole of a footwear.
Description
~ 1~3~o ~
SUMMARY OF TE~ INVENTION
This invention relates to antiskid device which is of simple and economical construction and applicable to most surfaces and footwear.
Several add-on devices intended to prevent the user from slipping on slippery surfaces have been known for many years. ~xamples of these are U.S. Pat. no.'s: 2,366,649; 2,425,939; 3,258,863; 3,616,552;
4,286,396; and 4,702,021.
While these prior art devices effectively fulfill their purposes, there are several disadvantages in each of them. The majority of them does not cover the whole bottom surface of the sole, so are unstable and uncomfortable to the user. Walking with a small part of the sole making contact with the ground means balancing while walking and gives an uneasy feeliilg.
Also the gripping means of these are usually constructed of sharp metal objects. While they are very suitable for the outside environment, they are unsuitable for indoor surfaces. It leaves no option for the user but to remove it constantly if they have to go inside and outside frequently. Other devices have the metal spikes molded into the sole.
Not only is this time consuming but also costly to manufacture. In order to be effective and useful these disadvantages has to be addressed.
This improved antiskid device was developed with the spikes covering the whole bottom surface of the sole, to provide more traction 2173now -and stable footing. Despite the large area covered by the sole of the device, it has a small thickness and when pressed together will occupy only a minimal amount of space.
me sole and spikes of this device is to be made of one uniform material preferably a wear resistant polymer like polyurethane, to simplify and economize in the manufacture of this product. Additionally, the use of this material would make the device suitable to outside surfaces whether it is ice or snow, and also to, normal indoor surfaces.
Still another object of this invention is to be easily attached or det~rhPA from the fooL- ~ar of the user and which can be kept in a special bag if the user desires to.
An illustration of the embodiments of the invention is carried out in the accompanying drawings wherein:
Fig. 1 is a left side view of the device secured on a shoe.
Fig. 2 is a top plan view of the device without the shoe.
Fig. 3 is a bottom plan view of the device.
Fig. 4 is a perspective view of the metal strip.
Fig. 5 is a perspective view of the bolt and nut.
Fig. 6 is a perspective view of the clip.
Referring to the drawings, the antiskid device (10) includes a sole (11) covering the whole bottom surface of the shoe (S). me sole (11) is of the same shape as that of the sole of the shoe (S) and has multiple spikes (12) extending downward from its bottom surface. me shape of the spikes (12) is in the form of a cone and has a sharp pointed end and is integral to the sole (11). me thickness of the sole (11) will be sufficient to su~olL the weight of the user and flexible enough so that when the shoe (S) is flexed the sole (11) will bend with it. me sole (11) and spikes (12) is constructed of one uniform polymeric material, preferably polyurethane which should be of sufficient hardness and wear resistant to be efficient. Attached also on the bottom surface of the sole (11) are three metal strips (14). me edges of these strips (14) are bent downward and has several narrow ends or teeth. me short sides of these has two teeth while the longer sides has three teeth each.
mese teeth provide a means for gripping a slippery surface, such as ice or snow, by biting into it when it comes into contact with the surface.

-The spikes (12) also will provide traction for the device (10) as well as stability and will prevent the metal strips (14) from damaging an ;n~oor surface by SU~l Ling some of the weight of the user and relieving some of the pressure from the metal strips (14). In return the metal strips (14) will minimize the wear of the spikes (12). These strips (14) are attAch~ to the sole (11) by bolt (15a) and nut (15b) and has a hole in the middle for the bolt (15a) to pass through. The nut (15b) has two special handle for easy adjusting and tightening. One of the strips (14) is placed in the edge of the heel portion of the sole (11) to make the initial contact when the user makes a step. The second strip (14) is placed in the middle portion and the third strip (14) is attA~h~ in the front and ball section of the sole (11) to provide traction when the device (10) is lifted to make another step. For attAch;ng the device (10) into the shoe (S), the sole (11) is provided with metal clips (13) along its sides. These clips (13)are made up of three parts, a first plate (13a) for holding the other two plates together, a second plate (13b) for gripping the sole of a footwear and a third plate (13c) for locking the second plate (13b) in place. The first plate (13a) has a longitn~;nAl slot in its middle part for the bolt (15a) to pass through and a small part of its one end bent perpendicularly. In this bent part, it has two protrusions with one hole each for holding the third plate (13c) in place and one protrusion with a hole for holding the second plate (13b) in place. The second plate (13b) has several rollnA~ teeth in one end and in the middle part, for gripping into the sole of the shoe (S) and two protrusions in the rear side for fitting in between the protrusions of the first plate (13a).
The teeth in the middle part is formed by pllnch;ng some portions of its area. In its other end, it has a protrusion for fitting into the bottom hole of the of the first plate (13a). The third plate (13c) is bent at an angle on both ends, with a rolln~ tip and two protrusion on one end for fitting into the two holes of the first plate (13a). It works as a locking device which when pressed into place will push the teeth of the second plate (13b) into the sole of the shoe (S) and ~ev~llt it from moving or slipping. The rollnAe~ tip of the third plate (13c) pushes the second plate (13b) tightly forward. The rounded shape of the teeth of '? 21 7 3 n 0 2 the second plate (13b) will prevent damage to the sole of the shoe (S).
The clips (13) will also be attached to the sole by bolt (15a) and nut (15b). The slot of the first plate (13a) is longitll~;nAlly spaced so that the clips (13) can be adjusted to the width or size of the sole of the shoe (S) If the shoe (S) is wide or long the clips (13) will be adjusted outward until the desired tigthness is achieved and if the shoe (S) is small or narrow, it will also be adjusted accordingly. But there is a limit to the size of the shoe (S) that the clips (13) can fit into, so the device (10) will be manufactured with a few sizes. And with only two kinds of material and of simple construction, this will greatly simplify and economize the manufacture of the device.
Having now therefore fully illustrated and described my invention, the embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:
