  • This invention pertains to exercising devices. More particularly, it pertains to exercising devices of the type adapted to be used by two people. The device is so arranged as to possess significant entertainment value.
  • This invention provides an improved, efficient, economical and effective exercising device which is adapted for use by two persons and which has high entertainment value.
  • the present exercising device is arranged so that each of two users of the device may operate the device at a level proportionate to his own physical strength without impairing the ability of the other user to operate the device at the same time at a different level proportionate to that individuals physical strength.
  • father and son may use the present exercising device together, and each may use the device in such manner as to obtain significant exercise, as well as entertainment value from the device.
  • the high entertainment value of the present exercise device encourages its use over extended periods of time by many individuals, up to four of whom may use the device at any given time as a group, each participating at his own level without impairing the entertainment and exercising benefits obtained from use of the device by others in the group.
  • the device is so constituted that games may be arranged for its use, such as games of competition between individuals in a group, or between groups of users where several exercising devices are available.
  • the present exercising device is arranged for use both indoors and outdoors and, thus, may be used on a year-round basis by all members of a family.
  • this invention provides an exercising device which includes a pair of flexible cords of substantially equal length.
  • the exercising device also includes a shuttle assembly which has a hole formed through it which is greater in diameter than the sum of the diameters of the cords.
  • the cords are passed only once through the shuttle assembly hole so as to be loosely journalled in the hole.
  • Means are connected to each end of each cord adapting each of the cord ends to be held securely in the hand of a user.
  • FIG. 1 is a view of the exercising device showing the shuttle assembly in cross-section
  • FIG. 2 is an elevation view of the shuttle assembly with the cords passing through it;
  • FIG. 3 is an enlarged cross-sectional elevation view of one of the two wear-resistant insert elements which are incorporated in the shuttle assembly shown in FIG. 1; and 1 FIG. 4 is a perspective view showing one of many possible modes of use of the exercising device.
  • An exercising device 10 includes a pair of elongate flexible cords 11 and 12 which are of substantially identical length.
  • the exercising device also includes a shuttle assembly 13.
  • shuttle assembly 13 is defined to resemble a solid of revolution which has a hole 14 formed through it along its axis of symmetry so that the hole passes through the center of mass of the shuttle assembly.
  • a handle element 15 is connected to each end of each cord. Between the handle elements, cords 11 and 12 are passed only once through the hole formed through the shuttle assembly so that the cords are loosely journalled within the hole.
  • FIG. 4 illustrates the use of exercise device 10 by a man 16 and a woman 17; it will be understood from the following'description, however, that the mode of use illustrated in FIG. 4 isonly one of the many manners in which exercising device 10 may be used by as many as four people at one time.
  • each of the two users of exercising device 10 grasps the handle at one end of cord 12 in one hand and the handle at the adjacent end of cord 11 in the other hand. The users then move apart from each other until cords 11 and 12 are relatively taut between them.
  • the shuttle is moved toward one or the other users until it is positioned closely adjacent the handles grasped in the hands of that person.
  • the person at the other end of the cord holds his: hands together, as shown in the case of woman 17 in FIG. 4.
  • the person adjacent whose body the shuttle is disposed then rapidly moves his hands apart while maintaining tension on the cords. This outward movement of the hands propels the shuttle along the cords toward the other person. Because the cords are loosely journalled within the shuttle, and the hole through the shuttle is straight, the shuttle moves along the cords toward the person whose hands are held together, and such movement occurs at a rate which is related to the rate at which the other person, such asman 16, actually moves his hands apart.
  • the mode of use of exercising device shown in FIG. 4 is merely but one of many possible modes of use of the present exercise device.
  • either or both of the users of the device may hold their hands together over their heads and move their hands downwardly apart from each other to propel the shuttle back and forth along the cords.
  • the users of the device may face away from each other and rely upon the feel" of the device as the shuttle moves back and forth along the cords to ascertain when the particular user should move his hands apart to propel the shuttle.
  • a user may lie on his back and engage his feet in respective ones of handles 15, and thereby operate the device by his legs rather than his arms.
  • the device may be operated by two people at one or both ends of cords 11 and 12. That is, one person may have control of the handles at one end of the cords of the exercising device, whereas at the other end of the cords each of two people may have control of one of the remaining two handles of the exercising device.
  • Shuttle 13 shown in the drawings, is provided in the exterior form of a solid of revolution, and preferably is elliszoidal in nature. That is, the outer surfaces of shuttle 13 correspond to the surface which is generated by rotation of an ellipse about its major axis.
  • An ellipsoidal configuration of shuttle 13 is preferred since such configuration results in a stream-lined shuttle which moves rapidly and efficiently along cords 11 and 12 as the exercising device is operated in the manner described above. It will be apparent, however, that shuttle 13 may be provided in the form of other solids of revolutions, such as spheres or the like, or may be provided in forms not consistent with that of a solid of revolution.
  • the hole through the shuttle through which cords 11 and 12 are passed be arranged so that the axis of the hole intersects and passes through the center of mass of the shuttle.
  • Such a relationship between the axis of the cord passage and the shuttle center of mass means that the shuttle is stable as it moves along the cords and does not wobble and unnecessarily consume the energy imparted to the device by unnecessary interaction between the shuttle and the cords; instead, the shuttle moves swiftly and smoothly along the cords from one user to the other.
  • shuttle 13 has a body which is fabricated in halves 21 and 22 which are geometrically identical to each other.
  • Each half 21,22 of the body has an outer wall section 23 and a tubular inner wall section 24, the inner and outer wall sections of each half of the shuttle body being joined to each other at mating edges 25 to which both the inner and outer wall sections of each half extend;
  • the inner and outer wall sections of each half of the shuttle body are faired into each other at their opposite ends, as at 26, as shown in FIG. 1.
  • halves 21 and 22 of shuttle body 20 are fabricated by injection molding techniques out of low density polyethylene, although it is within the scope of this invention that the shuttle body may be fabricated of high density polyethylene, or polypropylene, or whatever other material is desired.
  • the shuttle body is fabricated of low density polyethylene and has the hollow cross-sectional configuration shown in FIG. 1, the shuttle body is soft and resiliently deformable; this characteristic enables exercising device 10 to be used safely with minimum likelihood of harm to the user whether used indoors or outdoors.
  • each insert element 30 is fixed in hole 14 adjacent each of its ends to provide low-friction, abrasionresistant cooperation with cords 11 and 12.
  • each insert element is elongated and has a bore 31 formed through its length along an axis 32 of the element.
  • the outer diameter of each insert element along a major portion of its length is sized sufficiently greater than the inner diameter of hole 14 so that the insert elements may be fixed in position within shuttle body by an interference fit with the shuttle body.
  • a circumferential flange 33 is provided around the insert element at one end, as shown in FIG. 3.
  • This flange provides a convenient stop for proper positioning of the insert element in the shuttle body as it is force-fitted into hole 14 during fabrication of the exercise device.
  • bore 31 be tapered so as to increase slightly in diameter proceeding from that end of the insert opposite from flange 33 toward a flared outlet end 34 of the bore adjacent flange 33. Flare 34 is desired in the configuration of bore 31 to prevent unnecessary wear of cords 11 and 12 as the exercising device is operated, and also to minimize the friction which would be encountered between the insert element and the cords if the bore terminated at a right angle shoulder or the like.
  • the diameter of the bore at its smaller end is sized to be greater than the sum of the diameters of cords 11 and 12, it being preferred that cords l1 and 12 are of identical diameter.
  • the minimum diameter of bore 31 is on the order of about three times larger than the diameter of one of the cords.
  • cords 11 and 12 are provided by 1% inch diameter multistrand braided nylon cord of the type which is often commonly referred to as parachute cord.
  • nylon cord of the type which is often commonly referred to as parachute cord.
  • Such cord has the beneficial characteristics of being strong, flexible and relatively inelastic.
  • Other cord materials may be used, if desired.
  • Polypropylene cord is less strong and more elastic than nylon, but does have the additional beneficial property of being less abrasive than nylon cord in the context of this invention.
  • insert elements 30 are provided in shuttle 13 to provide abrasion-resistant lowfriction bearings for the cords as the shuttle moves back and forth along the cords during use of the device.
  • the insert material may advantageously be fabricated of a polycarbonate material such as LEXAN resin available from General Electric Company. It is within the scope of this invention, however, that other insert materials may be used such as polysulfone resins which have high melting temperatures, metals, ceramics such as porcelain, or compression molded materials such as phenolic resins or nylon.
  • cords l1 and 12 are fabricated of multistrand braided nylon
  • the cords be at least coated, and preferably impregnated with a material which provides a low coefficient of friction between the cords and insert elements 30.
  • the braided nylon cords are impregnated, not merely surface coated, with a wax.
  • WARCO 150-A yellow wax obtainable from E. S. Brown and Company, Los Angeles, may be used to advantage for this purpose.
  • This wax has a melting temperature of about 160 F and maintains its flexibility at temperatures as low as 30 F. Regardless of the particular wax or solid lubricant material used, it is desired that the material have a relatively high melting point in view of the friction generated between the shuttle and the cord as the shuttle is moved rapidly back and forth along the cords.
  • each handle 15 includes a grip portion 40 which preferably is straight and has substantial thickness so that this portion of the handle may be gripped securely in the hand of a user of the exercise device.
  • An arcuately curved guard portion 41 is connected across the opposite ends of grip portion 40 to impart a substantially D-shaped configuration to the entire handle.
  • the guard portion has a web element 42 which is smoothly curved in a semi-circular manner between the opposite ends of the grip portion, and which presents a smooth exterior to the outside of the handle.
  • a reinforcing rib 43 is connected to the concave surface of the web and extends along the entire length of the web.
  • each handle element 15 is fabricated of injection molded linear polyethylene. This material flexes sufficiently to provide an effective shock absorber in the operation of the exercising device. It should be understood, however, that the nature of the material from which the handles are made is not critical, and that any suitable material may be used, as desired.
  • each cord 11 and 12 is passed through a hole 44 formed through the guard portion of each handle adjacent the midlength of the grip portion of the handle.
  • the end of the cord is secured to the handle by knotting the cord, as at 45, in the space provided in the handle between the grip and guard portions.
  • the D-shaped configuration of the preferred handles described above adapts the handle for convenient engagernent in the hands of the user. Also, this handle configuration accommodates the front portion of the foot of a user of the exercising device so that the device may be used to exercise the leg muscles when used in the manner described above.
  • the two halves 21 and 22 of shuttle 13 may be fabricated of different colored materials.
  • the handles 15 may be fabricated of an entirely different colored material or may be of the same color as one of the halves of the shuttle.
  • each of cords 11 and 12 is defined by a 20 foot length of Va inch multi-strand braided nylon cord which has been impregnated with the WARCO ISO-A yellow wax identified above.
  • the shuttle of this exercising device is of the ellipsoidal form shown in the drawings, is 9 inches long, and has a 5 inch maximum outer diameter.
  • the minimum diameter of the bore 31 through each of the two insert elements 30 provided in the shuttle of this exercising device is three-eighths inch, and each insert element is 2 inches long; each insert element has an outer diameter of seven-eighths inch along a major portion of its length.
  • the cords of this exercising device are connected to the handle elements in the manner shown in FIG. 1, i.e., as by knotting after passing the cords through the hole formed in the guard portion of the handle element. This mode of connection of the cords to the handle elements makes it possible for the user of the exercising device to shorten the cords as desired.
  • cord lengths in the range of from 10 feet to 50 feet may be used effectively, although it should be noted that the longer the length of the cords the greater the physical strength required to operate the device to maximum advantage, both in terms of its properties as an exercising device and as an amusement or entertainment device.
  • An exercising device comprising a pair of cords of substantially equal length, separate means connected to each end of each cord adapting each of the cord ends to be separately held securely in a hand of a user of the device, a shuttle assembly having an axially straight, continuous hole completely therethrough which is greater in diameter than the sum of the diameters of the cords and through the entire length of which the cords are passed once only to be loosely journalled in and freely slidable through the hole and means located at opposite ends of said shuttle assembly to maintain said cords in substantially continuous parallel relation within said shuttle assembly.
  • Apparatus according to claim 1 wherein the means connected to each end of each cord comprises a handle element arranged to be gripped by a human hand and to receive a human foot.
  • each cord comprises a handle member having a grip portion and a guard portion connected across the grip portion and to which the corresponding cord end is connected.
  • said means at the opposite ends of said shuttle assembly includes an axially bored insert element received in the hole of the shuttle body at each end thereof for loosely journalling the cords, the bore of each insert having a diameter greater than the sum of the diameters of the cords.
  • each insert bore has a length which is substantially greater than its diameter.
  • Apparatus according to claim 1 wherein the hole has a minimum diameter on the order of at least about three times the diameter of one of the cords, and the hole has a length which is at least about 10 times greater than the diameter of the hole.
