Definitions

  • This invention relates generally to athletic shoes, and more particularly to an insert member for providing increased durability and rebound in athletic shoes.
  • the first broad category utilizes different materials and configurations of the midsole to improve cushioning as well as provide effective foot control.
  • materials of different hardnesses may be used to provide cushioning and foot control, or a variety of devices may be encapsulated in a midsole to increase cushioning.
  • This type of shoe has the disadvantage of a short life due to breakdown of the materials used to form the midsole. Since many shoes use only ethyl vinyl acetate (EVA) or polyurethane (PU) for cushioning, the cells of these foams have a tendency to break down and thus virtually eliminating the usefulness of the midsole. This in turn can cause serious injuries.
  • EVA ethyl vinyl acetate
  • PU polyurethane
  • the second category of device utilizes pneumatic devices within the midsole.
  • An example of this is taught in U.S. Patent No. 545,705, issued to McDonald.
  • the McDonald device is an elastic air filled cushioning device which is incorporated into the heel of a shoe to provide cushioning.
  • a similar device is taught in U.S. Patent No. 1,498,838 to Harrison Jr. which uses a number of tubes which lie within the midsole. These tubes are inflated by a valve to maintain a pressure above ambient.
  • the tubes in the Harrison Jr. device are made of a flexible inelastic material.
  • Stability is another problem with shoes which encapsulate gas within the midsole.
  • encapsulated gas midsoles are oftentimes too soft to give proper support.
  • the third broad category of devices which are intended to increase the cushioning of a shoe include outsole configurations.
  • An outsole is typically made of material such as rubber, polyurethane (PU), thermoplastic rubber (e.g., EVA) and the like. These materials are chosen for outsoles because they are wear resistant. Typically, these materials have fairly good memory characteristics. That is, if the outsole material is deformed either by compression or bending forces, it tends to return to its original shape.
  • U.S. Patent No. 4,372,058 to Stubblefield which teaches an outsole in which the periphery of the heel of the outsole maintains the remaining portion of the heel of the outsole in a spaced apart relationship to the ground. This configuration is known as a cantilever outsole.
  • the cantilever configuration helps to redirect vertical forces while increasing energy return to the midsole.
  • an outsole which has a plurality of lugs or levers which extend from the periphery of the bottom of the outsole. These lugs are designed to redirect vertical forces on the outsole so that the forces have at least a horizontal component thereby reducing the stresses on a runner.
  • the Stubblefield patent provides a shoe which provides both cushioning and stability.
  • the present invention is an insert member for use in an athletic shoe.
  • the insert member comprises a sheet of material which tends to return to its original. shape when deformed, the sheet of material having a plurality of undulations which spread laterally when depressed, characterized in that the undulations comprise parallel rows of peaks and valleys, each row being out of phase with an adjacent row.
  • FR-A-2507066 on which the preamble of claim 1 is based discloses an insert member for the sole of an athletic shoe which appears to work on a similar principle.
  • the insole described in that document comprises a sheet of material, the whole of which is deformed so that it forms a single row of undulations.
  • the present invention is defined by the characterising features of claim 1.
  • the rows of peaks and valleys of the insert member of the present invention are 180°C out of phase with the adjacent rows and that they have a substantially sinusoidal cross section.
  • the peaks and valleys will often be substantially circular.
  • the insert member may be formed from a sheet of material having uniform local thickness and may be in such a form that the peaks have a substantially uniform height and/or the valleys have a substantially uniform depth.
  • the insert member may be made from a thermoplastic polymer.
  • the insert member comprises a plurality of substantially circular peaks and valleys.
  • Figure 1 depicts a sole for an athletic shoe, designated generally as 10, which includes a number of component parts.
  • the sole 10 includes a midsole 12, which, like most athletic shoes, provides cushioning to the foot of a wearer.
  • the midsole 12 may be made of a material such as ethyl vinyl acetate (EVA) or polyurethane (PU) and may be formed from materials of differing densities.
  • EVA ethyl vinyl acetate
  • PU polyurethane
  • the medial side of an athletic shoe it is sometimes desirable for the medial side of an athletic shoe to be formed of a material having a higher density than that of the lateral side of the shoe. This is done in order to correct for certain biomechanical problems such as pronation.
  • many other midsole configurations may be used in conjunction with the invention.
  • the outsole 14 may be made of an abrasive resistant material such as rubber and includes a heel portion 16 which has a central heel portion 18 of the outsole 14 which may be in spaced relationship with the ground.
  • This relationship of the central heel portion 18 and peripheral portion of the outsole 14 is known generally as a cantilever outsole, an outsole orientation which is described in detail in U.S. Patent No. 4,372,058 to Stubblefield.
  • the heel portion 16 has a plurality of lugs 20 around the periphery thereof. These lugs 20 deflect outward upon the application of pressure onto the sole 10 and help to reduce shock to a wearer's foot upon impact with the ground.
  • a PU wrap member 28 is provided which is attached adhesively to the remaining portions of the outsole 14.
  • the PU wrap member 28 has a lateral extension 30 which helps to provide stability to the wearer's foot.
  • a medial extension 32 which is best seen in Figures 4 and 5. This midsole wrap helps provide stability by providing surfaces which tend to prevent excessive pronation or supination.
  • a conventional toe bumper 33 is used in conjunction with the wrap member 28, the medial extension 32 and lateral extension 30 may wrap over the bumper 33.
  • flexure grooves 34 are provided in the PU wrap member 28 in the metatarsal area. These help to provide bending of the sole in the area of the shoe where such bending is necessary in many athletic sports.
  • midsole 12 is provided with a heel component 36 which is made of a cushioning material such as polyurethane (PU). Also provided in the midsole 12 is a forefoot component 38.
  • the forefoot component 38 may include a forefoot foam 40 such as Ethyl Vinyl Acetate (EVA) or PU and may have a Shore C durometer hardness of approximately 50 or 60.
  • EVA Ethyl Vinyl Acetate
  • Forefoot foam 40 provides cushioning to the forefoot of a wearer.
  • the invention Is the use of a insert member 42 in conjunction with other component parts of an athletic shoe.
  • Figures 3-6 the insert member 42 used to practice the invention is illustrated; Figures 3-4 show the insert member 42 in cross-section in conjunction with other components of an athletic shoe; Figure 5 illustrates an exploded view of an athletic shoe embodying the invention; and Figure 6 depicts a sheet of material from which an insert member 42 may be formed. Even though Figure 6 is a sheet of material from which an insert member 42 is formed, it will be described below as if it were an insert member 42 since the only difference between the material shown in Figure 6 and an insert member is that Figure 6 shows material of arbitrary dimensions.
  • the geometric configuration of the insert member 42 gives the midsole of an athletic shoe increased life because much of the input energy is absorbed by the insert member rather than by midsole material.
  • the midsole may be lighter because less midsole material is necessary. Further, the midsole will return quickly to its relaxed configuration.
  • the insert member 42 is an undulating sheet of material which has a uniform local thickness.
  • This thickness (t) is typically about 1/32" (0.8mm) but may be tailored to a particular use. Naturally, the thickness may be greater or less than 1/32" (0.8mm) when used in the forefoot. For example, if the invention were to be used In a location other than the forefoot, it may need to have a greater or lesser thickness. Similarly, a non-uniform thickness may be used if different responses are desired for different portions of the insert member.
  • the overall shape of the Insert member 42 may, but need not, be substantially rectangular in shape. In the embodiment of the invention shown in Figure 5, insert member 42 approximates a rectangle with two rounded and two hard corners.
  • insert member 42 The precise overall shape of insert member 42 is not critical and it should be understood that the shape of insert member 42 can be tailored as desired.
  • the material forming the insert member has undulations which form a plurality of rows of substantially circular peaks and valleys.
  • a first row, designated as 44 in Figure 6, has a cross-section which is substantially sinusoidal. In this configuration, the magnitude of the amplitude of the peaks 46 and valleys 48 is the same and the wavelength of the sinusoidal cross-section is constant. These two geometric characteristics (constant amplitude and constant wavelength) are not critical to the invention and it is anticipated that a number of geometries could be used to practice the invention.
  • the spacing between peaks 46 in row 44 is approximately 11/16" (17.4 mm) and the magnitude of the amplitude of each peak and valley is approximately 3/32" (2.4 mm). In other words the thickness of the insert member measured from the maximum peak to the minimum valley is 3/16" (4.8 mm). Naturally, these values can vary depending on whether the insert 42 is to be used in, for example, the heel of an athletic shoe instead of in the forefoot.
  • a second row, designated as 50 in Figure 6, is positioned so that the first row 44 and the second row 50 are juxtaposed at a distance of one-half the distance between adjacent peaks 46 of the first row 44.
  • the second row 50 similarly has peaks 52 and valleys 54.
  • the second row is identical to the first row 44 except that the second row 50 is 180° out of phase from the first row 44. Every second row forming the insert member is in phase and all rows are 180° out of phase with its adjacent row.
  • the insert member is formed from a continuous quincunx arrangement. That is, the circular peaks of the insert member are arranged in a quincunx, the four sides of which are the sides of the adjacent quincunx arrangements. There are circular valleys formed between each of the circular peaks forming the corners of each quincunx arrangement.
  • a frame is provided for the insert member 42 by the forefoot foam 40.
  • a cutout is provided in which the insert 42 is positioned.
  • the insert member 42 can be made of many different materials as long as the material or combination of materials forming the insert 42 has good memory characteristics, is durable, and provides cushioning. By good memory characteristics it is meant that the material forming the insert, when deflected tends to return to its original configuration. This return to its original configuration should take place in a time frame which is less than the average period between deflections. For example, in a running shoe, the insert member 42 will deflect each time the foot contacts the ground in the region of the insert member 42. Therefore, it is important that when pressure on the insert member 42 is no longer exerted, the insert return to its original configuration prior to the next time the foot contacts the ground in the region of the insert member 42.
  • the insert member 42 In addition to having good memory characteristics the insert member 42 must be durable. It must be able to constantly withstand the cycling from a mode in which a force is exerted on the insert to a mode in which the insert is relaxed. In addition, the insert 42 must be made of a material which resists cracking due to either impact forces or due to fatigue; and must not have varying properties as a function of change of ambient conditions such as temperature and pressure.
  • One commercially available material which had these characteristics is Hytrel which is the registered trademark of a material which is manufactured by E.I. DuPont de Nemours. Hytrel is a chemically stable, semi-crystalline, fully polymerized, high molecular weight, thermoplastic polyester elastomer having alternate amorphous and crystalline chains.
  • Hytrel is selected as a material because of its ability to store energy upon impact and return that energy to the source.
  • Hytrel 4056 having a Shore C durometer hardness of 40
  • Hytrel 4074 also having a Shore C durometer hardness of 40
  • Hytrel 8236 having a Shore C durometer hardness of 82, are three materials (all DuPont) which may be used to practice the invention. It should be noted however that many other materials may be used to practice the invention.
  • the insert member 42 is generally positioned in the forefoot of an athletic shoe to improve the cushioning characteristics of the midsole by providing good memory characteristics and by returning energy to the midsole.
  • the insert member 42 when used in conjunction with forefoot foam 40, is generally positioned within forefoot cavity 56 ( Figure 5). This forefoot cavity 56 may extend completely through the forefoot foam 40 or may only be an indentation in the forefoot foam 40.
  • a cover 57 may be placed above insert 42.
  • the insert member 42 is cemented in place with a thin film of cement which attaches the crests of the peaks to the other midsole components such as the forefoot foam 40 (see point A, Figure 3) or the outsole 14 (see point B, Figure 3).
  • Figure 5 is an exploded view of an athletic shoe embodying the present invention.
  • the sole 10 has an outsole 14.
  • Above outsole 14 is a midsole having a heel component 36 and a forefoot component 38.
  • the forefoot component is made up of a forefoot foam 40 having a forefoot cavity 56 in which an insert member 42 as previously described is inserted.
  • Figure 7 shows a superimposition of some of the component parts of an athletic shoe embodying the invention.
  • Line 62 shows the interface between heel component 36 and forefoot component 38 (in a preferred embodiment, the interface between the PU and EVA which makes up the midsole);
  • lines 64a and 64b show the outline of the PU wrap member 28;
  • line 66 is the perimeter of insert member 42; and
  • line 68 shows the rearmost boundary of cover 57.
  • the insert member may be completely encapsulated within the midsole so that there are no air spaces between the insert and the midsole.
  • the insert member may be partially encapsulated.
  • one side of the insert member may have midsole material filling the valleys in that side.
