A shoe including: a body; a lower surface disposed on the body for contact with the ground; and at least one deployable traction element associated with the lower surface and having a retracted and a deployed position, the at least one deployable traction element providing additional traction when the at least deployable traction element is in the deployed position.
1. Field of the Invention
The present invention relates generally to shoes and attachments thereto, and more particularly to shoes having deployable traction elements.
2. Prior Art
Shoes that are worn by most people are prone to slippage on ice, snow, grass and other slippery surfaces. Shoe manufacturers have attempted to make the bottom surface of the shoes such that they better grip the ground surface. Shoes with protruding surfaces of various geometry are fabricated that increase resistance to slippage by digging into the snow and other surfaces that allow certain level of penetration by these protruding elements. However, for highly slippery surfaces, particularly those surfaces that are relatively hard and slippery and therefore resistant to penetration at relatively low pressure levels such as ice or hard snow, the aforementioned protruding surfaces cannot produce an adequate amount of traction. This is particularly the case since such protruding surfaces are commonly made of synthetic polymers that are relatively soft and used to make the shoe bottom and heel. As a result, the wearer can still slip on ice and the like.
To increase pressure between the aforementioned protruding elements and the ground surface, such elements have to be made with small surface area, i.e., to distribute the supporting weight over a small surface area to achieve a high contact pressure. To support the resulting pressure, the protruding elements, have to be constructed with relatively rigid and high strength materials such as steel or high stiffness and strong synthetic materials as relatively sharp “spikes”. During the walking over ice or other similar hard and slippery surfaces, the sharp spikes “dig” into the surface of the ice or hard snow, and provides for a significant traction between the shoe and the ice surface, thereby allowing the wearer to walk without slipping. Hereinafter, all protruding elements that are provided to increase traction between the shoe and the ground surface by “digging” into the surface such as ice or hard snow, are referred to as “spikes”, irrespective of whether they are integral part of a base plate, etc., or not.
A user wearing a shoe with the bottom surface covered with the aforementioned relatively sharp spikes can walk over ice, hard snow or the like with relative safety with little possibility of slippage. However, the user can wear the shoe only when on ice or the like. Wearing such spiked shoes can easily damage rugs, scar hard wood floors or other coverings indoors and would actually be unsafe over concrete and other similar hard surfaces since they would have a significantly lower friction than their aforementioned (softer) protruding elements. In addition, the spikes can damage asphalt and loose its sharpness. It is therefore desirable to wear such spiked shoes while walking over ice, hard snow or other similar surfaces and not indoors or over other outdoor surfaces.
A need therefore exist for methods and devices that would enable a person to wear shoes that are equipped with the aforementioned spikes to provide traction on ice, hard snow and the like, and returning the shoes to a no-spike wearing condition for use on other surfaces where such spikes are no longer needed for safe walking.
Such methods and devices may also be used in sports such as golf to allow the wearer to walk freely off the course, such as in the clubhouse and have appropriately spiked shoes for walking on grass. As a result, a wearer does not to carry an extra shoe and does not have to exchange shoes before going into the grass covered field.
Such methods and devices may also be used to provide traction for devices such as walkers, canes, crutches, and the like, where the user can use then to reduce the chances of slipping over ice, hard snow and the like.
SUMMARY OF THE INVENTIONAccordingly, a shoe is provided. The shoe comprising: a body; a lower surface disposed on the body for contact with the ground; and at least one deployable traction element associated with the lower surface and having a retracted and a deployed position, the at least one deployable traction element providing additional traction when the at least deployable traction element is in the deployed position.
The at least one deployable traction element can comprise: a first member attached to the shoe; a second member rotatably attached to the first member; and at least one spike associated with the second member. The one or more spikes can be configured to provide traction on ice or snow. At least some of the one or more spikes can be configured for football, golf, baseball or soccer. The first member can be associated with the lower surface by attachment with a fastener. The first member can be associated with the lower surface by embedding at least a portion of the first member in a corresponding hole in the lower surface. The lower surface can be on a heel of the shoe. The lower surface on the heel of the shoe can be adjacent a sole of the shoe.
A heel of the shoe can have a recess for holding the second member when the at least one deployable traction element is in the deployed position.
The shoe can further comprise a spring locking element associated with at least one deployable traction element to bias the at least one deployable traction element to stay in either the deployed or the retracted positions.
Also provided is a method for providing traction for a shoe. The method comprising: deploying at least one spike from a surface of the shoe such that the at least one spike provides additional traction when the at least one spike is in a deployed position; and retracting the at least one spike into a retracted position in which the at least one spike does not substantially provide the additional traction.
The method can further comprise configuring the at least one spike to provide traction on at least one of ice and snow.
The method can further comprise configuring the at least one spike for at least one of football, golf, baseball and soccer.
The method can further comprise biasing the at least one spike to stay in either the deployed or the retracted positions.
Still further provided is an athletic shoe comprising: a body; a lower surface disposed on the body for contact with the ground; and at least one deployable traction element associated with the lower surface and having a retracted and a deployed position, the at least one deployable traction element providing additional traction when the at least deployable traction element is in the deployed position, wherein the at least one spike is configured for at least one of football, golf, baseball and soccer.
The at least one deployable traction element can comprise: a first member attached to the shoe; a second member rotatably attached to the first member; and at least one spike associated with the second member.
These and other features, aspects, and advantages of the apparatus of the present invention will become better understood with regard to the following description, appended claims, and accompanying drawings where:
Although the present invention is applicable to numerous types of shoes, it is particularly useful in the environment of shoes for providing traction during walking on snow and ice. Therefore, without limiting the applicability of the present invention to shoes and attachments for providing traction on shoe and ice, it will be described in such environment. Those skilled in the art will appreciate that the shoes and attachments of the present invention can be utilized for general uses and for providing traction for sports, such as on golf shoes and baseball, soccer and football cleats.
The present invention provides spikes of various sizes and shapes that are distributed with some pattern and density over the bottom of shoes. The wearer is, however, able to remove or otherwise retract the spikes at will and with minimal effort. As a result, the user is provided with shoes with high traction over slippery surfaces such as ice, hard snow and the like, and is able to turn the shoe into a regular shoe that could be worn on any other surface where traction is not needed.

In another embodiment, the traction surface elements are designed to snap onto the shoe. One such embodiment is shown in the schematic side view of
In yet another embodiment, the traction surface element 40, as shown in

In yet another embodiment shown in
Another method of providing traction surface elements is provided where the spikes are retractable into a housing, such as the sole and/or heel of the shoe, or on a surface of the shoe, and are deployed by the user. The spikes may be those discussed above, such as being configured for snow, ice, football, baseball, soccer and golf. The deployment (and retraction) mechanism may require certain manual action or an action of the leg (foot). The deployment (retraction) action can be simple and easy to perform, particularly considering the harsh environment in which they have to be operated. In addition, since water, snow, ice, dirt, sand, etc., are almost always present, the mechanism can be capable of operating without hindrance in all such environments. The primary objective is to eliminate the need to change shoes and/or the need of putting the traction surface elements on when needed and taking them off when they are not needed (and possibly the need to carry around the traction surface elements in case they are needed).
In one embodiment of the present invention, the spikes are assembled into the shoe and are deployed or retracted at will by the user. In one such embodiment, the assembly is an integral part of the shoe. A side view of one embodiment is shown schematically in
The member 71 can be made as an angle 76 as shown in the side view of FIG. 11a, and is attached to the heel 73 by two set of nails (screws) 77 to more firmly attach the component 76 to the heel 73. However, the heel 73 can also have a recess 82 to receive the angle 76 as shown in
Alternatively, attachment housing with the retractable spikes can be attached to the shoe by the user using, for example, one of the attachment methods described in the embodiments of
Although the spikes shown in the figures are shown in two-dimensional rows, they can be disposed in any pattern on the base elements, such as patterns that are used in golf, baseball, football, and soccer shoes. The spikes can also be proved in a variety of sizes, such as being very small for ice and longer for snow.
While there has been shown and described what is considered to be preferred embodiments of the invention, it will, of course, be understood that various modifications and changes in form or detail could readily be made without departing from the spirit of the invention. It is therefore intended that the invention be not limited to the exact forms described and illustrated, but should be constructed to cover all modifications that may fall within the scope of the appended claims.
