Definitions

  • This invention relates to exercise apparatus.
  • principal objects of the present invention include first, providing an exercise device which is both compact and versatile, permitting many different types of exercise to be performed; and, secondly, providing a device which has a substantially constant resistance force, despite variations in the speed of actuation of the two arms relative to one another.
  • a compact, multi-purpose exercise device includes two telescoping arms which are pivoted together at one of their ends, and which are provided with handles at their other ends.
  • Each of the arms is made up of telescoping sections, and detents are provided for locking the telescoping sections together to provide lengths of the arms varying from about one foot to about three feet.
  • a hydraulic resistance unit is coupled to the ends of the arms which are pivoted together, and this hydraulic resistance unit provides substantially constant resistance to relative movement of the two arms despite changes in the speed of movement of the two arms relative to one another; and this is accomplished by a reverse Pelton bucket arrangement wherein the hydraulic fluid flow path of the hydraulic resistance unit is partially obstructed by a spring- biased element which moves backward against the spring pressure to reduce the hydraulic resistance, when higher velocity hydraulic fluid impinges upon the element.
  • a compact multi-purpose exercise apparatus includes telescoping arms which are pivoted together at one end, and which are provided with handles at the other end, and have a resistance unit coupled to the pivoted ends of the two arms.
  • an exercising apparatus includes two arms which are pivoted together and which has handles at the free ends of the arms, and is provided with a hydraulic resistance member having substantially constant resis ⁇ tance force with varying speeds of actuation of the two arms relative to one another.
  • This hydraulic resistance unit may be implemented by a reverse Pelton bucket which includes a spring-biased member in the hydraulic fluid path, with the spring-biased member being movable to reduce the resistance, with increased force of hydraulic fluid flow impinging on the spring-biased element.
  • the result is that with higher velocities, the movement of the Pelton bucket element serves to reduce the resis- tance and compensates for the normal increase in resistance as fluid is moved more rapidly through restricted passages.
  • Th reverse Pelton bucket element may include a sharply pointed member and in-curved bucket-shaped portions on either side thereof to receive and to respond to the jet of hydraulic fluid, to shift the Pelton bucket element.
  • the handles of the exercise device may be fully adjustable in their position from perpendicularity with the arms and substantial alignment with the pivot point of the units, to an orientation where they are substantially aligned with the arms. 3. Instead of single handles at the end of each of the arms, double handles or stirrups may be provided to facilitate actuation by the feet or the ankles.
  • rollers may be substi ⁇ tuted for the handles on one of the two arms, so that rowing or similar exercises may be more readily imple ⁇ mented.
  • the locking arrangements for holding the telescoping sections of the arms in fixed positions relative to one another may include thumb-operated detents associated with each of the outer telescoping sections, and openings in the inner sections, with closely spaced openings in at least one of the sections to permit substantially continuous adjustment of the lengths of the arms.
  • the ⁇ two arms may be mounted in immediate proximity to one another and may have the hydraulic resistance unit mounted outside in one direction, and a display unit mounted on the other side of the pivot point of the two arms.
  • a quick release mechanism may be provided for permitting prompt separa ⁇ tion of the components of the system for easy storage.

  • the handles 26 and 28 may be substantially continuously variable in their orientation between the position shown in solid lines in Fig. 1 at 26, 28 and the positions shown in dashed lines at 30, 32. This may be accomplished by having separate tapped holes into which the handles 26 and 28 may be secured, or by having ratchet-type mountings for the two handles permitting substantially continuous adjustment and fixation at any desired angle.
  • Each of the arms 22 and 24 are made up of a series of telescoping sections designated 22-1 through 22-4, for the four sections making up the arm 22, and similar ⁇ ly designated by the reference numerals 24-1 through 24- 4 for the four sections making up the arm 24.

  • the housing 34 is rigidly keyed to the inboard arm 22 by the reinforcing member 50.
  • the inwardly extending keys are shown in dashed lines at 52, 54 in Fig. 7.
  • the exercise arm 24 is reinforced by the member 56, which is in turn keyed to the rotating member 58 by inwardly directed portions of the arm 24 and the reinforcing member 56.
  • the member 58 is keyed to the shaft 48 upon which the vane 46 is mounted by special configuration of the inwardly extending end 60 of the rotating shaft 58, such as a "D" or “double-D” cross-sectional configuration, and a correspondingly shaped recess 62 in the shaft 48.
  • the quick release member 38 as shown in Fig. 7 includes the ball-bearings 64 which extend into an annular recess in the right-hand end of shaft 48.
  • the spring 66 normally biases the quick release actuator 38 in the right-hand direction as shown in Fig.
  • the left-hand end of the shaft 48 is provided with a bearing 70 and an 0-ring seal 72 where it interfits with the inwardly directed protrusion 74 from the housing 34.
  • the seal 72 may be made of 3 parts 72-1, 72-2, and 72-3, with 72-1 and 72-3 being ir the nature of O-rings as shown in Fig. 7 and wiper seal portion 72-2 extending along the edge of the vane 46 as shown in Fig. 4.
  • the housing 34 is made up of two parts, and they are held together by a series of threaded fasteners 76, with two peripheral 0-rings 78 and 80 being provided to seal the housing and retain the hydraulic fluid within the housing 34.
  • a resilient springy metal member 82 is provided with strain gauges 84 mounted on its upper and lower surfaces.
  • the member 82 is deflected by a spring 86 coupled toward the outer end of the outermost telescoping section 24-4, so that, as the arm is extended, the member 82 is deflected and the reading from the strain gauges 84 will represent the length of the arms.
  • This may be displayed on a display 88 as indicated in Fig. 1 and Fig. 8 of the drawings, for example.
  • the section may be provided with a hole or groove.
  • One of the features of the present exercise apparatus is the arrangements whereby substantially constant resistance force is provided, notwithstanding varying the speed of actuation of the two arms relative to one another.
  • This feature is accomplished by the use of a reverse Pelton bucket structure, which is shown in greater detail in Figs. 5 and 6 of the drawings.
  • Fig. 4 there are two Pelton bucket arrange ⁇ ments 90 and 92, and each of them is connected to both sides of the chamber divider 96 by the passageways 94.
  • the vane or ": .per" 46 is operative in one direc ⁇ tion
  • one of the reverse Pelton bucket devices is operative; and when the direction of movement of the wiper 46 is reversed by movement of the arms in the opposite direction, then the other of the two Pelton bucket assemblies becomes active.
  • fluid is applied to the chamber 90 through channel 94-1, and is discharged to the other side of the member 96 through the other channel 94-2.
  • the fluid is driven by the wiper or vane 46, it enters the channel 94-1 at very high velocities and impinges on the reverse Pelton bucket element 98, pushing it in the left-hand direction as shown in Fig. 6, against the force of the spring 100.
  • the reverse Pelton bucket deflects the fluid, creating a reaction force proportional to the velocity.
  • the Pelton bucket element 98 With relatively low velocity, the Pelton bucket element 98 remains relatively close to the seat 102, and a relatively high resistance is encountered for the hydraulic fluid flow from channel 94-1 around element 98 to channel 94-2.
  • spring 100 will be compressed, the element 98 will move back to the left, as shown in Fig. 6, and a significantly lower resistance path will be available between the input and output channels. This will counteract the normal significantly increased resistance encountered when an effort is made to force fluids through small passageways at high velocities.
  • the result is that a relatively constant resistance force is encountered when the two arms of the exercise apparatus are moved relative to one another, either at high velocities or at relatively slow velocities.
  • the level of force provided by the reverse Pelton bucket 98 is controlled by adjusting the tension of the spring 100 by shifting the position of the spring support member 104.
  • the enlarged end 106 of the threaded support member 104 is keyed to a pair of slots 108 in the opening 90 containing the Pelton bucket assembly.
  • ⁇ —. — * ___. -- ⁇ position of the spring 100 may be adjusted to vary the force applied to the reverse Pelton bucket element 98, thus controlling the level of force required to move the arms 22 and 24 relative to one another.
  • the Pelton bucket members may be individually adjusted so that a different force is encountered in moving the arms in one direction as compared with the opposite direction.
  • the Pelton bucket element is forced up against its seat 102, effectively acting as a one-way valve and forcing the flow of fluid to the adjacent Pelton bucket channel 92 as shown in Fig. 4.
  • FIG. 8 is an alternative showing indicating the display which is provided on housing 36 in greater detail. More specifically, a liquid crystal or LED display 88 may be provided. The information shown on the LED display may include the following: At the top, an indication of the number of inches which is the adjusted extent of arm 24, with the other arm normally being extended to the same distance. The second indication is that of the amount of force required to move the arms relative to one another. The pulse rate is indicated in the next reading and this may be implemented by a separate pulse measuring attachment which may be clipped onto the ear lobe or to a finger, for example, of the person who is exercising. This attachment is, of course, optional. The lowermost indication on the display is the number of minutes during which the exercising has been continuing.
  • FIG. 8 at the bottom of the display are calibration screw 47 and electronic display control buttons 49 and 51.
  • Figure 9 shows an enlarged view of the housing 34 together with the adjusting knobs and pointers 40 and 42. As mentioned above, these control the tension applied to the spring 100 within the Pelton bucket assembly. The scales on the two pointers indicate the relative resistance required for operating the arms in one direction and in the other direction, respectively.
  • Figures 10, 11 and 12 show in some detail the detent arrangements for holding the telescoping sections of the arms in the desired fixed positions relative to one another. More specifically, as shown in Figs. 10 and 11, the three larger sections of the arm, 24-1, 24- 2, and 24-3, are provided with thumb-actuated detents 112, 114, and 116, respectively.
  • the detent 112 is mounted in an open channel 118 on one side of the arm 24-1, and is mounted on a spring 120 with the head 122 of the detent 112 being accessible through an opening 124 through the outer wall of the arm section 24-1.
  • the head 22 of the detent 112 With pressure applied to the head 22 of the detent 112, its end 126 is released from th detent opening 128 in the next inner telescoping section 24-2 of the arm 24, so that the inner sections of the telescoping arm may be shifted outwardly toward the position indicated in Fig. 1 of the drawings.
  • the inner detents such as detent 114 and 116, are normally located so that telescoping movement of the sections of the arm is not hindered.

  • the hub 166 which is integral with the shaft 152, has an inwardly extending tubular member 168 which makes a close fit with the mating opening 170 at the end of the telescoping arm section 22-4, as shown in Fig. 18.
  • a recess 172 extends outwardly from the opening 170, and two metal balls 174 which are mounted and retained in holes in the sleeve 168, are forced out into the recess 172 when the release member 176 is forced to the right by the biasing pressure from the spring 178.
  • a flange 180 retains the member 176 as part of the handle assembly.
  • the balls 174 may move inwardly into the recesses or peripheral groove 182 in member 176, releasing the hub 166 from the telescoping arm member 22-4, and permitting adjustment of the angle of the handle, or the substitution of a different handle member.
  • Figure 20 is a showing of the handle assembly, with the hub 166 separate from the telescoping arm section 22-4.
  • a second handle member 188 provided with a stirrup 190, formed of flexible plastic cloth, leather, or other material, and with both of the two handles 162 and 188 being held in place by the threaded members 192 and 194 which may be knurled on their outer surface for ease in screwing them into place on the outer ends of the handle rods, such as that shown at 152 in Fig. 18.
  • Figure 21 is a cross-sectional view showing the hub 166 having the handle support shaft 152 extending in one direction, with the sleeve 160 and the grip 162 concent ⁇ rically mounted on shaft 152.
  • the cap member 192 holds the assembly together, with the stirrup 195 mounted as indicated in Fig. 21.
  • a second handle shaft 196 is threaded into the internal threads 164 in hub 166, and s similarly provided with a sleeve 198 which may rotate on the shaft 196, and an outer grip or handle 200 mounted on the sleeve 198.

Abstract

Dispositif d'exercice multi-usage compact comprenant deux bras de longueur réglable (22 et 24) que l'on fait pivoter ensemble à une extrémité et dotés de poignées d'angle (26 et 28) ou d'actuateurs réglables, à leurs extrémités opposées. On a prévu un membre à résistance hydraulique (34) au point de pivot des deux bras dont on peut régler la force sensiblement constante et qui est sensiblement indépendant de la vitesse à laquelle les poignées sont actionnées l'une par rapport à l'autre. La force est fournie par une auge Pelton inversée (98), comprenant un membre à ressort dans la trajectoire de l'écoulement du fluide hydraulique que l'on fait se déplacer afin de réduire la résistance de l'écoulement hydraulique avec la vitesse accrue de l'écoulement de fluide hydraulique. Le fluide hydraulique est dirigé vers l'ensemble à auge Pelton inversée (98) par une vanne (46) rotative dans une chambre (95) remplie de fluide hydraulique, à mesure que l'on fait tourner les bras (22 et 24) l'un par rapport à l'autre. Les deux bras du dispositif d'exercice se composent de quatre sections télescopiques (22-1 à 22-4) à détentes (112), actionnées par le pouce et montées à ressort, fonctionnant dans des ouvertures dans les sections de bras télescopiques internes, destinées à les maintenir à n'importe quelle extension voulue comprise entre environ 0,30 et 1m de longueur. Au lieu de poignées simples situées aux extrémités libres de chacun des bras, on peut monter des doubles poignées (134 et 136) ou des étriers pour un fonctionnement facile avec les pieds ou les chevilles d'une personne, on peut encore utiliser des roues à galets (132) afin de faciliter les exercices de type consistant à ramer.
