This application claims the benefit of Provisional Patent Application No. 61/617,166, filed Mar. 29, 2012 which is hereby incorporated by reference.
BACKGROUNDA toe and sole modification for footwear is disclosed which provides a smooth sole portion around the toe as a way to try and prevent stumbling or tripping by the elderly. Some of the concerns with the elderly include their ambulatory ability, their overall physical dexterity and their ability to adequately lift their feet, when walking, so as to avoid stumbling or tripping. When walking, if the feet are not lifted to a sufficient height above the support surface, the toe portion of the shoes can get caught, usually on carpeting. When the toe portion of the shoes (one or both) happen to drag and catch on carpeting, rugs and similar floor coverings, the person (often the elderly) may stumble or trip.
Although younger individuals, being more athletic and agile, can usually avoid stumbling and tripping, the elderly are at greater risk for two reasons. First, the elderly may have physical limitations or impairments which make it difficult to lift the feet when walking, at least to a height which is sufficient to avoid catching the toe portion of their footwear on the carpeting or rug. Secondly, the elderly may have difficulty in remembering to adequately lift their feet when walking. Even if the elderly are told that lifting their feet clear of the carpeting is important in order to avoid stumbling and tripping, the elderly may not always recall these instructions and thus continue with the bad habit which puts them at risk for stumbling or tripping.
Given these realities, an appropriate solution for helping the elderly is to design and construct a shoe with a toe portion and/or sole which is smooth and slippery. By adding a smooth and slippery layer to the sole and/or around the toe portion of each shoe, there is less risk that the toe portion of the shoe will become caught on carpeting as the elderly walk across the carpeting. It is the toe portion which is the most likely portion of the shoe to catch on the carpeting.
If we accept that one possible solution to stumbling and tripping by the elderly is to add a smooth and slippery layer to the sole and/or a toe covering to the footwear, the next task or challenge is how to do so. One option is to fabricate the original shoes with the desired modification(s). Another option is to be able to modify an existing pair of shoes by adding a suitable layer to the sole and/or a covering for the toe portion. Within each of these two options there are at least two species. One species for each option is to use a molding process which molds the covering directly to, over and around the toe portion. A second species for each option is to attach a separate layer or covering directly to the shoe. Within each species there are various subspecies. Further features which are contemplated include color variations and matching colors for the covering, as well as adding fluorescent illumination.
SUMMARYA shoe construction is disclosed which includes a sole portion having a toe end, a pivot location and a body extending from the toe end to the pivot location. The body has a thickness which increases between the toe end and the pivot location.
In another embodiment a sole portion construction for assembly to an existing shoe is disclosed wherein the sole portion includes a forward location, a rearward location and a body extending between the forward location and the rearward location. The sole portion body has a thickness which increases between the forward location and the rearward location.
A still further embodiment includes a method of modifying a shoe wherein the shoe includes a toe and a sole. The method of modifying includes the step of first providing a sole portion for assembly to the shoe wherein the sole portion includes a forward location, a rearward location and a sole portion body extending between the forward location and the rearward location. The method further includes the steps of shaping the sole portion around the toe of the shoe and then bonding the sole portion to the sole of the shoe.
For the purpose of promoting an understanding of the principles of the invention, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. Any alterations and further modifications in the described embodiments, and any further applications of the principles of the invention as described herein are contemplated as would normally occur to one skilled in the art to which the invention relates. One embodiment of the invention is shown in great detail, although it will be apparent to those skilled in the relevant art that some features that are not relevant to the present invention may not be shown for the sake of clarity.
Referring to
As used herein, the term “shoe” is intended to include any type of footwear, whether dress or casual, and without regard to style or materials. The conventional shoe portions include the upper, the heel and the sole.
Covering 22 is preferable a rigid synthetic member which is smooth and slippery against carpeting, rugs and similar floor coverings. In this manner when covering 22 drags against carpeting, for example, the slippery interface of covering 22 against the carpeting causes the toe portion of the shoe, including the sole portion beneath the toe to slip and slide. By not allowing the toe portion of the shoe to catch on the carpeting, the person wearing the modified shoes (designed for the elderly) is less likely to stumble and/or to trip on the carpeting when walking across the carpeting. As explained in the Background, the risk of stumbling and tripping is more likely with the elderly due to the factors which have been mentioned. By adding the disclosed covering 22 to the conventional pair of shoes (see shoe 20), the pair of shoes is converted into a pair of shoes suitable for the elderly who are prone to allowing their (uncovered) shoes to catch on carpeting causing the wearer to stumble and/or trip when walking across carpeting, a rug or a similar floor covering.
In the
Referring to
The manner of attaching the covering 22 to the shoe needs to be something which is secure and lasting. It is important that once the covering is attached that it becomes rigidly secured, does not come free, peel off, break or become dislodged. The covering 22 needs to last as long as the pair of shoes would be expected to last. One attachment option is to apply a layer of adhesive 32 between the covering 22 and the shoe (see
Another option for attachment of the covering 22 to the shoe 20 is to use a double-sided adhesive tape 36, see
The first embodiment which is disclosed in
An alternative embodiment, referring now to
Another embodiment for the original manufacture of a shoe with a toe covering portion 48 is illustrated in
The main sole portion 54 of sole 50 can be textured in any way desired as molded or cast. However, the front sole portion 52 needs to be smooth and slippery. By molding or casting sole 50 as a unitary member, the mold can be used to both texture main sole portion 54 and at the same time create a smooth and slippery surface for front sole portion 52.
In all of the embodiments described herein, it is contemplated that a specific material color for the covering or covering portion will be selected based on the remainder of the shoe. The selected color may be matching or contrasting at the designer's option. It is also contemplated that a fluorescent material might be used, at least for part of the covering, as a way to help the elderly find their shoes in darkness. While the adding of a fluorescent material could be a desirable feature or point of novelty for virtually any user, this feature would be particularly helpful for the elderly.
A still further design option for adding a toe covering to a pair of shoes is illustrated in
Referring to
Referring now to
Whether the sole portion of the shoe which is below the toe (extending back toward the location of flexure or pivoting) is integrated into the shoe when manufactured or is an after-market, add-on, the principle of use is essentially the same. The increased thickness of the sole portion which is closest to the pivot point or line of flexure raises the tip of the toe slightly and this in turn lessens the likelihood of toe-to-carpet contact. The key is that the sole portion includes a forward location toward the toe of the shoe and a rearward location toward the line of flexure or pivoting and an increase in thickness between these two locations.
An after-market cap 230 is illustrated in
When the heel of the shoe is raised off the support surface, the shoe bends in the ball of the foot area and becomes shorter in projected length. Then when the wearer of the shoe raises the toe of the shoe from the support surface, the shoe returns to the original length and thereafter the wearer must raise the shoe higher so as not to catch the toe on a rug, carpet or the support surface which could cause the wearer to trip and fall. One further improvement to what has been disclosed above would be to lock the shoe sole in the bent position and maintain that position until the heel and sole of the shoe are both on the support surface again. This is accomplished by cutting or molding a slit 260 across the bottom of the sole 262 of the shoe 264 (see
The inflatable tube 268 feature, including the slit 260 and chamber 266, requires a sole with sufficient thickness to receive a ¼ inch diameter tube and still have sufficient slit length to allow both flexure and movement of the tube 268 into the more narrow portion of the slit. Further, this feature is to be used in combination with the modified (i.e. increased thickness) sole shape and contour as described in conjunction with the structures illustrated in
