Abstract
A shoe suspension system and device are provided. In a first version of the Present Invention a device attached to an undersole of a shoe directs a spring force toward the ground in one direction and toward a heel section of the undersole of the shoe, whereby the heel section receives the spring force in an axis substantially normal to the undersole. In another version, a ground plate extends from a hinge, the hinge is attached to the shoe undersole, and a spring element is coupled at one end to the ground plane and at another end to the undersole, whereby a substantially planar orientation of undersole is supported by the device. In yet another version, a linkage including a plurality of hinges and arms is attached to a shoe undersole and directs a force toward a heel plane of the undersole.
Description
- 1. Field of the Invention
- The Present Invention relates generally to footwear. The Present Invention more particularly relates to footwear that provides both stability and cushioning.
- 2. Description of the Background Art
- The prior art and related art includes attempts to provide cushioning devices that are disposed between a foot and a ground surface to reduce the impact forces of locomotion. The prior art methods associated with an increase of cushioning brings with it some level of proportional decrease in stability. For this reason, the prior art has involved a compromise between cushioning and stability.
- The principal objective of the Present Invention is to provide a device coupled with, or in combination with, a shoe that sponsors the stability and cushioning of a foot wearing the shoe. These and other objectives of the Present Invention will be apparent to those skilled in this field from the following description of various aspects of the Present Invention.
- Towards this object and other objects that will be made obvious in light of this disclosure, a first preferred alternate aspect of the Present Invention includes a midsole device having a hinge, a ground plate and a spring element. The first preferred alternate aspect (hereafter “first midsole device”) may be coupled with, or be comprised within, the footwear (hereafter, “shoe”). The hinge is positioned to rotate about a hinge axis that is substantially normal to a longitudinal heel-toe axis of the shoe. The ground plate is rotationally coupled with the hinge, and is configured to position the spring element to provide a spring force toward a heel of a wearer and a spring force against a ground surface.
- Certain alternate aspects of the Present Invention comprise one or more of the aspects of (1.) two or more spring elements; (2.) two or more hinges; (3.) one or more spring loaded hinges; (4.) one or more living hinges; (4.) multiple hinges and arms, each arm coupled with two hinges; (5.) one or more pinned hinges; and (6.) one or more rear plates, each rear plate for supporting the wearer's heel or foot.

Themidsole block 12 ofFIG. 1A could be framed by two stiff bucklingcolumns 38 optionally made from polyurethane that would run for the length of thefirst midsole block 12 along the heel-toe axis providing spring force to thefootwear 1. Additionally the columns' 38 rigidity would limit movement of the midsole device in the direction of the heel-toe axis. Furthermore thesecolumns 38 could optionally be constructed with a side bias in order to ensure the same direction of collapse with applied weight. The rest of themidsole block 12 shape would be constructed of adurometer source material 40 exhibiting low rigidity providing general shape support for the block. Thedurometer source material 40 may be or comprise EVA material, e.g., EVA foam. The column geometry and material properties are configured to achieve stiff, low vertical displacement whilst undergoing typical walking loads and compliant, high vertical displacement whilst undergoing typical running loads. This arrangement allows the cushioning forces to only react to loads that exceed a predetermined level. - Referring now generally to the Figures and particularly to

The placement and number of these stiff bucklingcolumns 38 could vary according preference. One or more stiff bucklingcolumns 38 would be placed at various locations within the midsole blocks 12B to provide spring force and rigidity, while a less rigid lowerdurometer source material 40 could fill in the gaps of the block to maintain shape. - Referring now generally to the Figures, and particularly to
