Definitions

  • This invention generally relates to footwear, and more particularly, to a suction al ⁇ leviation system configured for footwear, particularly boots.
  • suction creates serious problems for the pedestrian. As the resistance at ⁇ tributable to the suction can be substantial, it makes walking a very strenuous activity that leads prematurely to exhaustion. Second, overcoming suction can create a discernable noise that can give away one's position or alarm a nearby animal.
  • the invention is directed to overcoming one or more of the problems as set forth above.
  • a suction alleviation system for footwear includes a conduit having an entrance and an exit and a port disposed on the sole of the footwear.
  • the conduit is fluidly coupled to the port.
  • a valve e.g., a flapper valve or spring actuated valve
  • the valve When open, the valve enables fluid (e.g., air or water) communication from the conduit to the port and to the valve.
  • the com ⁇ municated fluid alleviates suction.
  • the system provides a valve-enabled path for controlled communication of fluid (e.g., air or water) to the sole of the footwear for al ⁇ leviation of suction.
  • the conduit includes a first section and a second section and the system further includes a junction adapted for coupling the first section to the second section.
  • a junction adapted for coupling the first section to the second section.
  • the system also including a support configured for securing the conduit against the footwear.
  • a support configured for securing the conduit against the footwear.
  • a loop, stitching, bonding, hook and loop fasteners and the like may be used.

  • Figure 2 shows a flapper valve for use in accordance with an exemplary imple ⁇ mentation of the invention.
  • Figure 3 is spring actuated valve in accordance with an exemplary methodology in accordance with one implementation of the invention.
  • a suction release system generally includes a bottom port, a valve adapted to prevent mud and debris ob ⁇ structing the bottom port when the valve is closed, a top port for allowing entry of fluid (e.g., air or water), and a conduit for communicating fluid (e.g., air or water) from the top port to the bottom port.
  • a suction force causes the valve to open.
  • fluid e.g., air or water
  • fluid may be drawn from the top port through the conduit to the bottom port.

  • the system may include a plurality of top ports, plurality of bottom ports and plurality of conduits.
  • the system may provide multiple paths for communication of fluid (e.g., air or water) to the sole of the footwear for alleviation of suction.
  • the exemplary suction alleviation system may also include a junction 130 for removably attaching a first portion of a conduit 115 to a second portion of conduit.
  • the junction 130 enables removal of a portion of the conduit 115 when it is not needed or for repair or replacement.

Abstract

Un système atténuant l'aspiration comprend un conduit ayant une entrée et une sortie ainsi qu'un orifice disposé sur la semelle de l'article chaussant. Le conduit est couplé de manière fluidique à l'orifice. Une valve située au niveau de l'orifice s'ouvre en réaction à une aspiration. Ainsi, ce système fournit un chemin activé par la valve pour une communication régulée de fluide (par exemple, air ou eau) avec la semelle de l'article chaussant dans le but d'atténuer l'aspiration. Plusieurs orifices, conduits et valves peuvent également être utilisés. Le conduit peut comporter une jonction pour faciliter le retrait, la réparation ou le remplacement d'un segment. Un support peut être utilisé pour fixer de manière fiable le conduit contre l'article chaussant.
