Anti-slip overshoe
Disclosed is a foldable anti-slip overshoe for wearing over an item of footwear, comprising a lower section for placement beneath at least a portion of the sole of the footwear, and an upper section comprising a toe section, a heel section, and a vamp section, configured to fit over at least a portion of each of the toe, heel and vamp of the footwear respectively, wherein a lower surface of the overshoe is provided with at least one anti-slip feature.
The present invention relates to the field of footwear and, more particularly, to an improved overshoe for preventing slipping.
Movement across a slippery surface, such as one which is snowy, icy or wet, is generally difficult and even dangerous when wearing standard footwear, which provides poor traction on such surfaces.
The need to walk slowly or with small steps over a slippery surface is inconvenient, time-consuming, and requires concentration, thus interfering with a person's ability to be aware of their surroundings and to be alert to other hazards such as approaching motor vehicles and other pedestrians.
The inconvenience of walking on slippery surfaces interferes with businesses that require outdoor work to be done when conditions are icy. Postal and parcel delivery, for instance, is hampered, as well as baggage handling, road repair, ambulance and emergency work, police work, and any outdoor work that cannot be stopped for inclement weather.
Runners, joggers, and persons that exercise outdoors are hampered by the loss of traction on slippery surfaces. For example, even if outdoor surfaces are slightly slippery, a jogger must take smaller strides to avoid slipping. Activities that require movement faster than a slow walk are greatly hindered in inclement conditions by a lack of suitable footwear.
Further, even the knowledge that roads and sidewalks are slippery can be detrimental. The knowledge that outdoor walking conditions are hazardous may discourage persons from engaging in normal activities. For instance, a person is more likely to choose not to walk to a store, to take a pet for a walk, or otherwise leave home if the person knows that walking conditions are slippery.
This problem is especially acute for the elderly or persons with disabilities that interfere with a standard gait. Many elderly persons experience impediments to walking that make them more likely to slip and fall under normal conditions; and in climates where snow and ice persists through a significant portion of the winter, some k elderly persons become essentially home-bound. Similarly, a disability that causes an irregular gait may discourage a person from undertaking normal activities when outdoor walkways provide sub-par traction; for example, the loss of a leg may create an irregular gait that leads to added vulnerability to slipping.
Injuries due to slipping on snowy or icy surfaces are common, especially in the elderly or others having brittle bones.
In addition, a common problem is that people desire to wear stylish or expensive shoes. Exposure of such shoes to the elements, especially salt and moisture damages these shoes. A person is therefore forced to wear a second pair of shoes outside and change the second pair to the stylish or expensive shoes once inside. This is inconvenient and impractical.
U.S. Pat. No. 6,836,977 teaches an anti-slip overshoe for fitting over a person's shoe for minimizing slippage on a ground surface. The overshoe is formed from an elastic material which fits over substantially the entirety of the sole of the shoe, and is held in place by portions which enclose and grip the toe and the heel of the shoe. The background art overshoe must stretch to fit around a shoe, but not stretch and move while the user is walking, such that stretch zones are incorporated into the overshoe, increasing the complexity of manufacture. Since the background art overshoe is held on the shoe only by elastic gripping at the heel and toe portions, the overshoe may easily come off during use.
There is thus a widely recognized need for, and it would be highly advantageous to have, an anti-slip overshoe for a shoe, or other item of footwear, which overcomes at least some of the limitations of the prior art.
SUMMARY OF THE INVENTIONAccording to one aspect of the present invention there is provided an anti-slip overshoe for wearing over an item of footwear, comprising a lower section for placement beneath at least a portion of the sole of the footwear, and an upper section comprising a toe section, a heel section, and a vamp section, configured to fit over at least a portion of each of the toe, heel and vamp of the footwear respectively, wherein a lower surface of said lower section is provided with at least one anti-slip feature and wherein the overshoe is foldable (by which is also meant rollable).

Referring now to
Lower section 14 is formed from a flexible, semi-rigid material, and is provided with at least one anti-slip feature 20, which increases traction and reduces or minimizes slippage of the wearer while moving on a slippery surface. Anti-slip feature 20 may comprise, for example, a protrusion such as a rubber spike, a stud, a raised feature studs 20a or raised bars 20b, or the like. In overshoe 10 anti-slip features 20 are spaced apart in a pattern, whereby each anti-slip feature 20 is adjacent to a space of at least the dimensions of the anti-slip feature, such that when overshoe 10 is rolled up, each anti-slip feature is positioned within one such space, enabling overshoe 10 to be stored in a compact form.
According to some embodiments of the present invention (e.g., overshoe 10 depicted in
As seen in
According to some embodiments of the present invention (e.g., overshoe 10 depicted in
According to some embodiments of the present invention (e.g., overshoe 10 depicted in
Lower section 14 and upper section 18 may be integrally formed. Alternatively, upper section 18 may be connected to lower section 14 by a plurality of detachable fasteners (not shown). Optionally, upper section 18 may be provided as an integrally-formed unit comprising toe section 32, vamp portion 36, back section 28, and instep section 40. Alternatively, all or some of toe section 32, vamp portion 36, back section 28, and instep section 40, may be provided as separate, detachable, straps which may be reversibly connected to form upper section 18 of overshoe 10.
Although overshoe 10 is illustrated for use on a sneaker, it should be appreciated that the design may easily be adapted for use with any item of footwear, including any type of shoe, boot, or sandal, having any height of heel. For example, the overshoe is suitable for use over a high-heeled shoe, preferably by addition of at least one further lower strip (not shown), in addition to lower heel section 24, wherein the additional strip is positioned beneath the arch of the footwear, such that lower portion 14 follows the contours of sole 16 of shoe 12. In embodiments of the invention, especially configured for use with high heel shoes, the toe section is provided with an opening through which the point of the toe of a shoe can protrude. When used, the toe of a shoe protrudes through the opening through the toe portion of the overshoe, encircling the toe of the shoe and thus holding the overshoe of the invention tightly associated with the shoe. Such an embodiment is especially suitable for use with shoes having relatively pointy toes.
As with overshoe 10 depicted in
Lower section 14 is formed from a flexible, semi-rigid material, and is provided with a number of anti-slip features 20, which increase traction and reduces or minimizes slippage of the wearer while moving on a slippery surface. For overshoe 80, anti-slip features 20 comprise small studs 20d, large studs arranged in clusters 20e and a raised chevron 20f. In

To ensure that vamp section 36 is held tightly against a shoe, overshoe 80 is provided with two straps on each side. Strap 82 (a similar strap is found on the non depicted side of overshoe 80) is an elastic strap that ensures that the lower and middle portions of vamp section 36 are held tightly against a shoe. Openable strap 84 (a similar strap is found on the non depicted side of overshoe 80) is an adjustable strap provided with a fastening feature 44 (as described above) that allows easy wearing of overshoe 80 over a shoe and ensures that the upper portion of vamp section 36 and heel portion 28 are held tightly against a shoe.
Flaps 70 are secured, as shown in
As with overshoes 10 and 50 depicted above, the lower section of overshoe 60, undersole 62, is provided with at least one anti-slip feature 20, which increases traction and reduces or minimizes slippage of the wearer while moving on a slippery surface. Anti-slip features 20 of overshoe 60 consist of a plurality of raised chevrons. In overshoe 60 anti-slip features 20 are distributed in such a way (with a sufficiently large separation) as to provide good traction but also to not interfere with folding or rolling of overshoe 60, enabling overshoe 60 to be stored in a compact form.
In addition to anti-slip features 20, proximal to the front of the lower section of overshoe 60, undersole 62, is sharp feature 76. Sharp feature 76 is configured to dig into packed snow when a user takes a forward step and thus give a user an added measure of traction for forward motion.
The upper surface of undersole 62 of overshoe 60 is provided with at least one anti-slip feature configured to frictionally engage footwear held inside overshoe 60 so as to prevent slippage of the footwear and thus provide a user with more stability. Specifically, the internal anti-slip features of overshoe 60 are protrusions 72.
As is clear to one skilled in the art upon perusal of the description, addition to protecting the wearer against slippage, overshoe 60 protects the footwear from becoming wet or soiled when walking on icy, snowy or wet surfaces, which is particularly useful for people who do not wish to carry a spare pair of footwear such as shoes or boots for traveling under such conditions, but still wish to arrive at their destination with their footwear dry, intact, and unsoiled.
Any of the embodiments of the present invention described above may preferably be formed of a lightweight, waterproof material, having sufficient elasticity and durability for the purposes of the present invention, and which may be rolled into a compact form for easy and convenient storage and transport, such as any suitable natural or synthetic elastic polymer or co-polymer. Non-limiting examples of suitable materials include natural rubber, polyisoprene, polybutadiene, polychloroprene, silicone, polyurethane rubber, polyacrylic rubber, epichlorohydrin rubber, polysulfide rubber, and the like.
The overshoe may optionally be provided in a variety of colors, and/or include additional decorative features, for aesthetic and commercial purposes.
It is expected that during the life of this patent many relevant overshoes will be developed and the scope of the term overshoe is intended to include all such new technologies a priori.
As used herein the term “about” refers to ±10%.
Additional objects, advantages, and novel features of the present invention will become apparent to one ordinarily skilled in the art upon examination of the following examples, which are not intended to be limiting. Additionally, each of the various embodiments and aspects of the present invention as delineated hereinabove and as claimed in the claims section below finds experimental support in the following examples.
