Description
- The present invention relates to an expander type exercise device.
- Expander type exercise devices are also referred to as pulling exercisers or strand-pulling exercisers. Such exercisers are intended to aid in performing a plurality of physical exercises that are conducive to improve the fitness of body muscles. Such exercise devices may serve to replace barbells or dumbbells for performing physical exercises.
- Some typical expander type exercise devices are described in the following references.
- U.S. Pat. No. 399,699 issued to Sachs on Mar. 19, 1889 and entitled “Exercising apparatus,” shows a typical embodiment of a strand-pulling exercise device in which five elastic bands, either rubber or metallic springs, are individually respectively secured between handles. U.S. Pat. No. 2,930,614 issued to McIntosh on Mar. 29, 1960 and entitled “Body exercising device,” discloses five separate elongated resilient, rubber, tubes connected between two handgrips. The tubes according to McIntosh are connected at the handgrips by way of ball elements. U.S. Pat. No. 3,677,543 issued to Richardson on Jul. 18, 1972 and entitled “Elastic pull type exerciser,” discloses a single piece of elastic tubing with loops formed at the respective ends of the tubing that serve as the handgrips. An anchoring element is disposed at the portion of the tubing opposite to the handgrips. The anchoring element provides the counterweight for the pull type exerciser according to Richardson. U.S. Pat. No. 4,019,734 issued to Lee at al. on Apr. 26, 1977 and entitled “Elastic pull type isotonic/isometric exerciser,” discloses a single, elastic, resistant length of latex rubber with respective handle portions to perform pulling exercises. U.S. Pat. No. 4,762,318 issued to Phillips et al. on Aug. 9, 1988 and entitled “Exerciser,” discloses a single tension member that can be varied in length between two handgrips. U.S. Pat. No. 5,662,564 issued to Nelson on Sep. 2, 1997 and entitled “Exercise device,” discloses a structure that includes a single belt. The single belt serves to resist swinging movement of an upper housing upon movement of a handle assembly that is actuated during an exercise. The belt is connected to a pair of sprockets that cooperate with a further, centrally located, sprocket. The centrally located sprocket meshes with the cogs on the pair of sprockets, such that rotation of the centrally located sprocket in clockwise or counter-clockwise directions will rotate the adjacent sprockets in opposed directions to thereby adjust the tension of the single belt. U.S. Pat. No. 5,885,196 issued to Gvoich on Mar. 23, 1999 and entitled “Multiple elastic cable exercise device,” discloses three elastic cables, the respective ends of which are secured in the respective handles by way of conical plugs. U.S. Pat. No. 5,894,631 issued to Chiu on Apr. 20, 1999 and entitled “Handle structure for a chest pull,” discloses a handle with a tapered passage for a sphere member that is sized to be movably retained in the tapered passage.

Elastic element 30 is disposed in eight portions betweenhandgrip 21 andhandgrip 21′. Theelastic element 30 is preferably an elastic tubular element, such as, sold under the trademark THERABAND. THERABAND is used in physical therapy clinics and is available in drugstores and similar outlets. THERABAND is produced by THERABAND INC., Akron, Ohio, in various colors and sizes, colors being yellow, red, green, blue, and black. The colors may indicate different tensile strengths or expansion and contraction properties or the resistance grade. PRIMELINE INDUSTRIES of Akron, Ohio, produces similar tubular elements. The size of thetubular element 30 may be in the range of from {fraction (1/8)} inch outer diameter and {fraction (1/32)} inch wall thickness with {fraction (1/16)} inch inner diameter, to V2 inch outer diameter with {fraction (1/8)} inch wall thickness and {fraction (1/4)} inch inner diameter and all manufactured and possible sizes in between and other sizes and dimensions as desired for a given situation. Thetubular element 30 may be selected with a tensile configuration that is useful for a beginner of myexercise device 20, for an advanced user of myexercise device 20, or an intermediate user of myexercise device 20. However, other elastic elements that can be expanded from its original state by application of a pulling force and that contract upon release of the pulling force to its original state may equally be used. -
FIG. 2 is an illustration of my expandertype exercise device 20 in the configuration that is regarded as the basic configuration of theelastic element 30 betweenhandgrip 21 andhandgrip 21′. This configuration is particularly intended for performing physical exercises that develop and/or strengthen the muscles of the arms and upper torso of auser 10. -
FIG. 2 shows a first, right,handgrip 21 that has a handle portion orgrip portion 22 that is configured to be gripped by a hand of auser 10. Connected next to handleportion 22 is a pair ofside members handle portion 22 to a rollerelement mounting portion 24 that is configured to mount and dispose four rollers, 25.1, 25.2, 25.3, and 25.4. -
FIG. 2 further shows a second, left,handgrip 21′ which correspondingly comprises a handle portion orgrip portion 22′ that is configured to be gripped by the other hand of auser 10, in this illustration, the left hand. Connected next to handleportion 22′ is a pair ofside members 23 a′ and 23 b′ that serve to connect thehandle portion 22′ to a rollerelement mounting portion 24′ that is configured to mount or dispose four rollers, 25.1′, 25.2′, 25.3′, and 25.4′. Thus, thehandgrips device 20, however, it is within the scope of my invention that the handgrips are dissimilar, but would each provide a means to mount or dispose the roller elements 25.1 to 25.4, and 25.1′ to 25.4′ as is illustrated inFIG. 2 . - The
elastic element 30 is disposed about the two pairs of four roller elements orrollers 25 each, as is described next: Commencing from roller 25.1,portion 30 a ofelastic element 30 extends to the left to roller 25.1′ and is disposed about roller 25.1′. The extent or portion ofelastic element 30 from the roller 25.1′ to the roller 25.2, on the right side, is designated 30 b. Similarly,portion 30 c ofelastic element 30 extends from roller 25.3′ to roller 25.2, andportion 30 d extends from roller 25.3′ to roller 25.4.Portion 30 e extends from roller 25.4′ to roller 25.4.Portion 30 f extends from roller 25.4′, overportion 30 d, to roller 25.3, andportion 30 g extends from roller 25.3 to roller 25.2′ by passing underportion 30 c. Finally,portion 30 h extends from roller 25.2′ to roller 25.1 by passing overportion 30 b. - It will be appreciated that in this described example of my expander
type exercise device 20, theelastic element 30 is disposed to give a rather firm resistance to pulling as would be desired by auser 10. In other words, the expandertype exercise device 20 according to my invention provides, in this described embodiment, a greater resistance to being pulled than a single strand. -
FIGS. 2A and 2B illustrate possible cross-sectional configurations of thehandle portion 22.FIG. 2A shows a substantially square cross-section withwalls FIG. 2B illustrates a substantially circular cross-section withflat sides handle portion 22 are within the scope of my invention. - Merely by way of example, the distance between the
handgrips FIG. 2 may be approximately 32 inches. - My device is not limited to the configuration of
elastic element 30, about therollers 25, that is shown in and described with reference toFIG. 2 . - Thus, the
elastic element 30 of thedevice 20 is capable of being rearranged as is illustrated inFIG. 3 . InFIG. 3 , theright handgrip 21 is modified with respect toFIG. 2 , by roller 25.2 not carrying a portion ofelastic element 30. The arrangement ofelastic element 30 inFIG. 3 is as follows:Portion 30 a extends from roller 25.1 to roller 25.1′ on the left. Theelastic element 30 is then passed about rollers 25.2′ and 25.3′ and continues asportion 30 d to roller 25.4 by passing underportion 30 f.Portion 30 d is passed over roller 25.4 and continues asportion 30 e to roller 25.4′ and there becomesportion 30 f that extends between roller 25.4′ and roller 25.3 to continue asportion 30 g from roller 25.3 to roller 25.2′ and thence asportion 30 h between roller 25.2′ and roller 25.1. It will be appreciated that the foregoing description refers to the winding of theelastic element 30 about the eight rollers in the illustrated manner to achieve a six portion configuration of theelastic element 30 between thehandgrip 21 and thehandgrip 21′. In comparison with the configuration illustrated inFIG. 2 , a greater resiliency of theelastic element 30 is produced thereby to permit carrying out of less strenuous physical exercises with my expandertype exercise device 20. - As mentioned, merely by way of example, the distance between the
handgrips FIG. 2 may be approximately 32 inches. - By temporarily removing, for example, roller 25.2 at
handgrip 21, to remove the loop ofelastic element 30 that was passed about roller 25.2, upon stretchingelastic element 30 between thehandgrips FIG. 3 , the distance between thehandgrips - For sake of convenience so as not to misplace the roller 25.2 and its corresponding
pin 26, (FIG. 2 ) whichpin 26 is illustrated in greater detail inFIG. 13 , the roller 25.2 may be conveniently re-connected by way of its correspondingpin 26. - With reference to
FIG. 4 , theelastic element 30 is disposed in four portions about therollers 25, as follows:Portion 30 a extends betweenhandgrips portion 30 d extends over roller 25.4, andportion 30 e extends from roller 25.4 to roller 25.4′, thence under roller 25.3′ and over roller 25.2′, and, asportion 30 h, to roller 25.1. In other words, in order to achieve the described configuration ofelastic element 30 according toFIG. 4 , the rollers 25.2 and 25.3 are removed, by removing the corresponding pins 26, and by pulling theelastic element 30 between thehandgrips pin 26 through thebores 25 c (FIGS. 11 and 12 ) in therollers 25 and thebores 24 h (FIGS. 6, 7 , and 8) inhandgrips - With references to
FIG. 5 , theelastic element 30 is disposed withportion 30 a about rollers 25.1 and 25.1′ and withportion 30 e about rollers 25.4.′ and 25.4. - As has been mentioned, merely by way of example, the distance between the
handgrips FIG. 2 may be approximately 32 inches. InFIG. 3 the distance may possibly be 48 inches. InFIG. 4 the distance may possibly be 56 inches. InFIG. 5 the distance may possibly be 93 inches. Each increase of the distance affording a reduction of the force that is to be applied by a user. The full length of the elastic element may be approximately 15 feet to approximately 16 feet, it being understood that these dimensions are merely examples of possible embodiments and that other dimensions are within the scope of my present invention. It will be appreciated thatelastic element 30 has two ends that are suitably joined, such as, by clamping or by a connection with a cylindrical structure that is disposed at the adjacent ends of theelastic element 30 and the ends and the pin structure are fastened together to provide a continuouselastic element 30 that is placed about the rollers or pulleys 25, as described herein above. -
