Primary Examiner-Richard C. Plnkham Assistant Examiner-11. G. Strappello Attorney-Flam & Flam [57] ABSTRACT A butterfly exercising apparatus includes a pair of cranks pivotally mounted to a table supporting frame assembly for butterfly-like arcuate motion. Movement of either crank handle is transmitted by a cable and pulleys to a lever arm the free end of which is hinged to the bottom of a weight displacing shaft. A set of weights, adapted to slide along guide rods depending from a pivotable support member, are pinned to the shaft. Arcuate motion of either or both crank handles moves the lever arm, shaft and weights up and down, providing a selectable weight resist to the person using the exerciser.
11 Claims, 2 Drawing Figures BUTTERFLY EXERCISE MACHINE BACKGROUND OF THE INVENTION 1. Field of the invention The present relates to a butterfly exercising apparatus wherein arcuate motion of a pair of crank handles is resisted by a selected set of remotely situated weights displaced by the crank handle motion.
2. Description of the Prior Art Certain body muscles advantageously are exercised by holding dumbbells and moving the arms through an arcuate paths resembling, with some imagination, the flapping of butterfly wings. As the person increases in ability or muscle tone, more heavily weighted dumbbells are employed; often these become of unwieldy size, with concomitant danger should the weights accidentally be dropped.
Certain exercising devices employing remotely situated, selectable weight stacks are known in the prior art. Typical of these is the leg press described in U.S. Pat. No. 3,1 16,062 to Zinkin. That exercising apparatus includes a bell crank having foot receiving pedals at one end and pivotally connected at the other end to the top of a weight lifting rod. The user presses his legs against the pedal to rotate the bell crank and lift the weights. While useful for leg exercises, such an assembly is not suitable for butterfly type arm exercises.
These and other limitations of the prior art are overcome by the present invention, an objective of which is to provide a butterfly exerciser including handles gripped like dumbbells, but connected to a remotely situated, selectable stack of weights.
SUMMARY OF THE INVENTION To accomplish the foregoing objective, there is provided a butterfly exercising apparatus having a pair of cranks mounted to a table supporting frame assembly and adapted for arcuate, butterfly-like motion. The crank handles are connected by a cable and pulley assembly to a lever arm extending beneath the table on which the user may recline. The free end of the lever arm is hinged to the bottom of an upwardly extending weight displacing shaft, to which a selectable set of weights is pinned. The weights themselves are adapted to slide along a pair of guide rods which depend from a transverse member pivotally mounted at the top of an upwardly extending frame assembly. Butterfly motion of either or both crank handles is transmitted via the pulley and cable assembly to move the lever arm against a selected weight resist.
BRIEF DESCRIPTION OF THE DRAWINGS A detailed description of the invention will be made with reference to the accompanying drawings, which are to scale.
FIG. 1 is a perspective view of the inventive butterfly exercising apparatus.
FIG. 2 is a fragmentary, transverse sectional view, as seen generally along the line 2-2 of FIG. 1, showing the butterfly exerciser lever arm and weight displacing shaft in raised position.
DESCRIPTION OF THE PREFERRED EMBODIMENT The following detailed description is of thebest presently contemplated mode of carrying out the invention. This description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention best is defined by the appended claims.
Referring now to the drawings, the inventive butterfly exerciser 10 includes a pair of cranks ll, 12 having respective crank handles 11a, 12a situated on either side of a body supporting table 13. A user, reclining on the table 13, grips the handles 11a, 12a and rotates one or both of the cranks 11, 12 about respective horizontal axes defined by the crankshafts 11b, 12b. Motion of the cranks ll, 12 is transmitted via a cable and pulley assembly, generally designated 14, to a lever arm 15. The free end 15a of the lever arm 15 is hinged to the bottom of an upwardly extending, weight displacing shaft 16. Certain of the weights 17 are connected to the shaft 16 by a pin 18 so as to be moved up and down in response to user imparted butterfly motion of the crank handles 11a, 120. As described below, positioning of the pin 18 permits selection of the amount of weight resisting movement of the cranks 11, 12.
The cranks 11, 12 are supported by a frame assembly 22 including upright members 22a, 22b extending from a footing 22c and spaced on opposite sides of the table 13. A transverse member 22d extends between the uprights 22a, 22b to support one end of the table 13. The crankshafts 11b, 12b are attached to the respective uprights 22a, 22b.
The other end of the table 13 is supported by an inverted U-shaped member 23 extending upwardly from a footing 24. The lever arm 15 is situated generally beneath the longitudinal centerline of the table 13, and is pivotally attached at the fulcrum end 151) to a fitting 25 on the footing 24. r
The cable and pulley assembly 14 includes a single cable 26 the ends of which are attached to the respective crank arms 11c and 12c. The cable 26 is guided around and beneath the table 13 by a pair of pulleys 27, 28 mounted to the uprights 22a, 22b and another pair of pulleys 29, 30 mounted to the table supporting member 22d. The center of the cable 26 engages a pulley 31 attached to the lever arm 15 at a location between the uprights 22a, 22b. With this arrangement, upward arcuate motion of one or bot'h'crank handles 11a, 12a pulls the cable 26, raising the pulley 31 and causing the lever arm 15 to pivot upwardly about the fulcrum end 15b.
The upward motion of the lever arm 15 is transmitted to the shaft 16 which extends through the vertical openings 17a in each of the weights 17. Each weight 17 is provided with a horizontal hole 17b extending from the front surface to the vertical opening 17a. The pin 18 is inserted through the hole 17b of a selected weight 17' into the corresponding one of a plurality of radial bores 16a in the shaft 16. Thus the shaft 16 lifts the pinned weight 17' and the other weights above it in the stack 17, as to the: raised position shown in FIG. 2.
The weights l7 slide along a pair of guide rods 33 which extend through vertical holes 17d in each weight. The guide rods 33 depend from a transverse support member 34 pivotally mounted across the top ofa frame assembly 35 including a footing 35a and a pair of uprights 35b and 350. The lower ends of the guide rods 33 support a transverse member 36 having a clearance hole 360 through which the weight displacing shaft 16 extends. A pair of coil springs 37 surround the guide rods 33 between the weights 1'7 and the transverse member 36 to cushion the downward impact as the weights are lowered into the rest position shown in FIG. 1.
The weights l7, guide rods 33 and lower transverse member 36 together are free to swing about the horizontal axis defined by the pivot pins 340 at the ends of the upper supporting member 34. This limited arcuate motion accommodates the horizontal component of motion of the bottom of the shaft 16 as the lever arm pivots about the fulcrum end 15b.
Thus there is provided a novel butterfly exercising apparatus in which user manipulated crank handles are moved against the resistance of a remotely situated stack of weights.
