-
Patent number: 11039656Abstract: The footwear cushioning invention includes a floating elastic plate that stores and returns elastic energy to provide cushioning through deflection of the elastic plate. Cushioning is by energy return rather than the compression of a foam. Footwear cushioning utilizes a deflection plate integrated into the heel of the shoe for providing shock attenuation and energy absorption when a wearer impacts a hard surface with the shoe. The deflection plate can be carbon fiber because it increases energy return and minimizes energy loss. A cavity can be formed in a midsole of the shoe underneath the deflection plate to allow the plate to flex into the cavity when pressed down upon by a wearer's heel, thereby accepting the energy of a downward step. A post can be located in the center of the cavity underneath the deflection plate that allows support and minimizes excessive deflection of the deflection plate.Type: GrantFiled: July 12, 2013Date of Patent: June 22, 2021Assignee: OPVET, Inc.Inventor: Daniel E. Norton

Publication number: 20030217483Abstract: A complete energy absorbing system for a variety of items, including athletic shoes. To accomplish the foregoing, the invention utilizes a series of encapsulated springs that are always in a state of suspension. Such is a result of the unique stiffening of the conical spring during compression thereof. In the preferred mode, the encapsulated springs are conical in nature, and alternate between standard and upside-down orientation, providing the utmost in strength and support while preventing the springs from bottoming out upon impact. Importantly, as distinguished from the prior art, an encapsulating material placed around a plurality of conical springs prevents the springs from being continually placed in a stressed situation, thus maintaining their structural integrity. Such encapsulating material may be made of a polymeric or thermoplastic material, which conforms to the conical shape of the springs and their respective apertures, functioning to aid in the dissipation of impact forces.Type: ApplicationFiled: May 24, 2002Publication date: November 27, 2003Inventor: Carl J.

Patent number: 6601042Abstract: The present application teaches a device and method for adjusting the width, girth, and foot shape of an article of footwear. Lasting boards having different configurations and alternate positions for selectively affixing various portions of an upper can be used to adjust and customize the fit of an article of footwear for an individual wearer. The lasting board can also comprise a spring element which can provide improved cushioning, stability, running economy, and a long service life. Unlike the conventional foam materials presently being used by the footwear industry, the spring element is not substantially subject to compression set degradation and can provide a relatively long service life. The components of the article of footwear including the upper, insole, lasting board and/or spring element, and sole including possible midsole and outsole portions can be selected from a range of options, and can be easily removed and replaced, as desired.Type: GrantFiled: May 17, 2000Date of Patent: July 29, 2003Inventor: Robert M. Lyden

Patent number: 6594918Abstract: An article of footwear has an upper in a tented arrangement. The article of footwear includes a sole and an upper including a shroud. The article of footwear further includes a foot engaging system for joining a foot of a user to the sole, and a biasing system which includes a plurality of frame members that urges or influences the shroud away from the foot of the user. The article of footwear further includes a plurality of straps for holding the foot to the sole in which one of the straps engages the heel. The straps are located on an exterior surface of the shroud or alternatively they are located in the interior of the shroud. Air gaps are created between the shroud and the foot for ventilation. Several foot booties for holding a foot have vent openings for providing air to ventilate the foot of a wearer. Further, the foot booties are combined with straps, in which the straps are disposed between the shroud and the foot booties.Type: GrantFiled: January 22, 2002Date of Patent: July 22, 2003Assignee: Nike, Inc.Inventors: Tinker L. Hatfield, Michael A. Aveni, Michael R. Friton

Patent number: 6562427Abstract: An airbag for shoes has a plurality of elastically compressible cylindrical cushion members which are interconnected in a predetermined array by a connecting plate. The cushion members/connecting plate combination is encapsulated in a casing. The cushion members, connecting plate and casing are joined together to form an integral unit. The cushion members have a spiral groove formed in their outer surface which increases their compressibility during the initial phase of compression.Type: GrantFiled: October 11, 2001Date of Patent: May 13, 2003Assignee: Chinook Trading CompanyInventor: Hun-Fa Hung

Publication number: 20020189134Abstract: An athletic shoe includes substantially horizontal chamber substantially within a heel portion of a midsole, the chamber having atmospheric communication at its lateral sides. The chamber includes an upper substantially rigid horizontal plate having at least four apertures therein and a lower substantially rigid horizontal support plate having a corresponding plurality of at least four apertures. Flexible resilient unitary sleeves integrally join respective vertical pairs of the apertures of the upper and lower plates respectively. Disposed within each of said resilient sleeves are resilient means each having spring constant and spring rate greater than that of said sleeves.Type: ApplicationFiled: June 18, 2001Publication date: December 19, 2002Inventor: Roy Dixon

Patent number: 6449878Abstract: The article of footwear taught in the present invention includes a spring element which can provide improved cushioning, stability, running economy, and a long service life. Unlike the conventional foam materials presently being used by the footwear industry, the spring element is not substantially subject to compression set degradation and can provide a relatively long service life. The components of the article of footwear including the upper, insole, spring element, and outsole portions can be selected from a range of options, and can be easily removed and replaced, as desired. Further, the relative configuration and functional relationship as between the forefoot midfoot areas of the article of footwear can be readily modified and adjusted. Accordingly, the article of footwear can be customized by a wearer or specially configured for a select target population in order to optimize desired performance criteria.Type: GrantFiled: March 10, 2000Date of Patent: September 17, 2002Inventor: Robert M.
