Definitions

  • the current invention relates to an apparatus, accessories, and method for selecting various lengths or resistance of an elastic exercise cord or band.
  • FIGs. 1A-1F are figures from US Patent Number 5,131,650 to Hall which describes an exercise device including an elongated exercise bar of non-circular cross-section having end members that include throughbores and a conical recess extending outwardly from the throughbore, and a slot
  • the elastic cable member includes one or more internally positioned plug members that provide local enlargement of the cable and are adapted to cooperate with the conical recess to securely position the cable with respect to the end member and to prevent the cable from passing through the end member when tension is applied to the cable.
  • an adjustable resistance exercise cord has a plurality of selectable, spaced-apart, tapered stops provided on a first end portion of the cord. Any of the tapered stops in the first end portion may be removably attached to a handle, a surface clamp, a foot retention element, an exercise device, or other cord restraint device.
  • the user may adjust the working resistance of the cord by selecting different tapered stops.
  • the tapered stops closer to the first end of the cord will permit a longer un-stretched length from the second constraint point to the handle or other restraint device, so that the force required to expand the cord is relatively low.
  • the tapered stops further from the first end of the cord will create a shorter un- stretched length from the second constraint point so that the force required to expand the cord is relatively high. This arrangement permits a user to quickly change a desired length or resistance of a single cord, rather than having to change cords for various exercises.
  • the elastic cord is hollow and the tapered stops have internal tapered plugs and external tapered covers configured to fit over the tapered plug area.
  • the tapered plug and the tapered cover are tapered in a similar profile as a tapered receptacle in a cord retention element on a handle, bar, surface clamp, foot retention element, abdominal exercise device, or other cord restraint device.
  • the tapered cover provides a highly visible indicia of color, symbol, letter, or number so that a user can readily distinguish the various tapered stops.
  • the covers also increase friction on the tubing wall. Friction between the tapered plug and the inside cord tubing wall resists slippage of the tapered plug as the elastic cord is stretched.
  • the tapered cover includes a lip portion of reduced diameter that provides additional slip resistance.
  • One benefit of having both an internal tapered plug and an external tapered cover is the improved slippage resistance provided by both internal and external wall friction.
  • an adjustable resistance exercise cord has a first plurality of selectable, spaced-apart, tapered stops provided on a first end portion of the cord and a second plurality of tapered stops on a second end portion of the cord. Any of the tapered stops in the first end portion may be removably attached to a first end portion cord restraint device. Any of the tapered stops in the second end portion may also be removably attached to the same or a different cord restraint device. The user may adjust the resistance of the cord by selecting different tapered stops on one or both end portions. Selecting tapered stops that are closer together provides a cord which requires relatively higher force for expansion, while selecting tapered stops that are further apart provides a cord which requires relatively lower force for expansion. This arrangement also permits a user to quickly change a desired length or resistance with a single cord, rather than having to change cords for various exercises.
  • This arrangement also permits a high degree of selectivity of cord working length and resistance. For instance, if there are four tapered stops on the right end of a cord and four tapered stops on the left end of the cord, then there are 7 possible different unstretched length and working resistance settings when all right end stops have the same spacing as the left end stops; 10 possible different unstretched length and working resistance settings when the right end stops have the same variable spacing as the left end stops; or up to 16 different unstretched length and working resistance settings when the right end stops have different spacing than the left end stops.
  • a pair of removable handles and an abdominal exercise device are provided along with one or more adjustable resistance band in a kit.
  • the removable handles are configured with tapered stop receptacles to permit the user to insert a selected tapered stop in one or both removable handle in order to obtain a desired elastic cord working length.
  • the abdominal exercise device has a right handle with a right tapered stop receptacle and a left handle with a left tapered stop receptacle.
  • the abdominal exercise device includes a central platform with one or more pairs of tapered stop receptacles.
  • FIG. 1A is a front view of a portion of an elastic cord with an internal plug, where the plug is oriented for inserting into a receptacle on the end of a bar.

Abstract

L'invention concerne une corde d'exercice à résistance réglable ayant une pluralité de butées sélectionnables et espacées qui peuvent être insérées amovibles dans des réceptacles de retenue de corde sur des poignées, des barres, des éléments de retenue de pied, des dispositifs d'exercice, ou d'autres dispositifs de retenue de corde. Lorsqu'une seconde partie de la corde d'exercice est limitée, l'utilisateur peut régler rapidement la résistance de travail de la corde par sélection de différentes butées coniques. Dans un exemple, la corde élastique est creuse et les butées coniques ont des bouchons coniques internes et des couvercles coniques externes conçus pour être emboîtés sur la zone de bouchon conique. Le couvercle conique fournit un indice de couleur, de symbole, de lettre ou de nombre très visible de sorte qu'un utilisateur puisse facilement distinguer les diverses butées coniques. Dans un exemple, l'utilisateur peut régler la résistance de la corde par sélection de différentes butées coniques sur au moins une des deux parties extrémité d'une corde.
