The apparatus has a plurality of exercise members mounted on a frame for different prescribed exercise movements by the user, a resisting force producing arrangement, and a cable for selectively connecting the resisting force to the different exercise members. The cable is guided and supported by pulleys, one of which is adjustable from one position to another to accommodate the different exercises.

Description

BACKGROUND OF THE INVENTION1. Field of the Invention

This invention relates generally to exercise equipment and more particularly to a novel exercise apparatus for performing a variety of exercises all utilizing the same resisting force producing means for resisting the exercise movements of the user.

2. Prior Art

The ever increasing popularity of physical fitness has led to the development of a vast assortment of exercise devices. These devices range from the very simple, such as dumbbells, jump ropes, and the like, to relatively complicated and sophisticated exercise machines or apparatus designed for the performance of several different exercises. The present invention provides a novel exercise apparatus of this latter kind.

Exercise apparatus of the kind to which this invention pertains utilize various means to provide the required resisting forces for the various exercises which may be performed on the apparatus, that is the forces for resisting the exercise movements of the user. In some cases, these forces are developed by spring. In other cases, weights provide the required resisting forces. These weights are generally adjustable to vary the resisting force. Weights have the advantage over springs of providing relatively smooth and uniform resisting forces which remain essentially constant throughout the range of movement of the exercise members.

SUMMARY OF THE INVENTION

This invention provides improved exercise apparatus for performing several different exercises all of which utilize the same means to provide the required resisting forces for the exercises. As will appear from the ensuing description, the present invention may utilize either weights or springs to provide this resisting force. The preferred resisting force means, however, and that utilized in the disclosed and presently preferred embodiment of the invention is a weight stack.

The exercise apparatus of the invention may be designed to perform various exercises. The presently preferred embodiment of the invention, for example, may be used to perform chest and shoulder press exercises, a leg extension exercise, a pectoral fly exercise, and a variety of other leg, arm, and body exercises. All of these exercises utilize the same means, preferably a weight stack, for providing required resisting force for the exercises.

To this end, the exercise apparatus of the invention has a plurality of exercise members mounted on a common frame for different prescribed exercise movements relative to the frame corresponding to the different exercises to be performed on the apparatus. In the disclosed and presently preferred embodiment of the exercise apparatus, for example, these exercise members are a pivoted chest and shoulder press exercise arm, a pivoted leg extension exercise arm, and a pair of pectoral fly exercise arms. A single weight stack is supported on the frame for vertical movement relative to the frame and is attached to a cable which may be selectively connected to the exercise members in such a way that the exercise movements of these members raises and lowers the weight stack to resist such movements. This single weight stack is utilized in all of the exercises which may be performed on the apparatus.

According to an important feature of the preferred embodiment of the invention, the weight stack cable is supported and guided by an upper pulley mounted adjacent the top of the frame above the weight stack and a lower pulley mounted adjacent the bottom of the pulley with the cable extending upwardly from the weight stack over the top pulley and then downwardly under the bottom pulley to the particular exercise member(s) to which the cable is attached. The bottom pulley is adjustable between a first position in which the weight stack cable may be attached to the chest and shoulder press arm without obstructing the chest and shoulder press exercise and another position or other positions for accommodating the other exercises to be performed on the apparatus.

Mounted on the apparatus frame are seats for supporting the user while performing certain of the exercises, such as the chest and shoulder press exercises, leg extension exercise, and pectoral fly exercise of the preferred embodiment. According to an important feature of the invention, the seat for the press exercises has a backrest which is adjustable between upright and forwardly inclined positions for supporting the user's upper body in the proper attitude for the chest and inclined shoulder press exercises, respectively.

According to a further feature of the invention, the weight stack cable may be releasable from all of the exercise members for engagement with a user's hand, leg, or body to perform various other leg and body exercises.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Turning now to these drawings, the illustrated, presently preferredexercise apparatus 10 of the invention has aframe 12 mounting a number of

exercise members

14, 16, and 18. These exercise members are operable, by a user, through prescribed exercise movements, relative to theframe 12 and corresponding to the different exercises which may be performed on the apparatus. The particular exercise members shown are a chest and shoulder press exercise arm (item 14) for performing chest and shoulder press exercises (FIGS. 1 and 2), a leg extension exercise arm (item 16) for performing a leg extension exercise (FIG. 11) and pectoral fly exercise arms (items 18) for performing a pectoral fly exercise (FIG 9). Other exercises, such as those depicted in FIGS. 6 through 8, may be performed on the exercise apparatus, as well.

Also mounted on theapparatus frame 12 is asingle means 20 for providing an adjustable resisting force for all of the exercises which may be performed on theexercise apparatus 10. As noted earlier, this resisting force means may comprise a string or weight. The preferred resisting force means, however, is the illustrated weight stack. For this reason, the resisting force means 20 will be hereinafter referred to as a weight stack.

Attached to theweight stack 20 are cable means 22 for selectively connecting the weight stack to the

exercise members

14, 16, and 18, as shown in FIGS. 1 through 5 and 9, and for engagement by the user's hand, legs, or other body part, when performing other exercises such as those shown in FIGS. 1 through 8. The cable means 22 are arranged in such a way that the exercise movements of the

exercise arms

14, 16, and 18 in FIGS. 1 through 5, 9 and 10, and of the user's hands and legs in FIGS. 6 through 8, raises and lowers theweight stack 20 whereby the latter provides a resisting force for all of the exercises performed on the apparatus. The effective weight of the weight stack is adjustable to vary this resisting force.

Seat means 23 are provided on theframe 12 for seating the user while performing various exercises. In the particular exercise apparatus shown this seat means includes a seat 23a which is used when performing the chest and shoulder press exercises and the leg extension exercise and aseat 50 which is used when performing the pectoral fly exercise.

Referring now in more detail to the drawings, theapparatus frame 12 is essentially a tripod frame including three generally

upright frame members

24, 26, 28 joined at their upper ends by atop frame part 30. Adjacent the bottom of theframe 12 is a T shapedbase frame section 32. This base frame section includes aframe member 34 extending between and joined to the

upright frame members

26, 28 adjacent their lower ends and atransverse frame member 36 extending laterally from the center offrame member 34 toward and beyond theupright frame member 24. The lower end of theframe member 24 is secured to theframe member 36. Joined to the outer end of thelateral frame member 36 is anupright leg 38. The lower end of this leg and the lower end of the

upright frame members

26, 28 form three support feet for theframe 12.

The chest and shoulderpress exercise arm 14 hangs downwardly from thetop frame part 30 to the right (in FIG. 1) of theupright frame member 24. This press arm includesside bars 40 rigidly joined near their upper ends and at their centers bycross bars 42. The upper ends of theside bars 40 are hinged at 44 to thetop frame part 30 for swinging of the lower end of thepress arm 14 generally lengthwise of thebase frame member 36 and toward and away from theupright frame member 24. Fixed to the lower ends of the pressarm side bars 40 are handles 46 and 48 to be selectively gripped by the user.Handles 46 extend laterally from opposite sides of the press arm.Handles 48 extend downwardly from the press arm.

The seat 23a for supporting the user when performing chest and shoulder press exercises includes aseat member 50 situated below thepress arm 14 and abackrest rest 52.Seat member 50 has a rear end secured to theupright frame member 24 and an opposite front end secured to the upper end of theframe leg 38.Backrest 52 is hinged along its lower edge at 54 to the upper frame member 24 a sprawled distance aboveseat member 50. Thebackrest 52 is rotatably adjustable about its lower pivot axis between its generally upright position of FIGS. 1 and 3A and its forwardly inclined positions, relative to theseat member 50, shown in FIGS. 2, 3B and 3C.

Secured to and extending rearwardly from the rear side of thebackrest 52 is asupport member 56 havingmeans 58 engagable with theupright frame member 24 for retaining thebackrest 52 in its various positions of adjustment. Theparticular support member 56 shown is ayoke having arm 60 which straddle theframe member 24. The backrest support means 58 is a pin which is selectively insertable through

holes

62, 64 in theyoke arm 60 for engagement with theframe member 24, as shown best in FIGS. 1, 3A, 3B, and 3C, to retain thebackrest 52 in its various positions of adjustment.

The legextension exercise arm 16 comprises a dependingbar 66 hinged at its upper end to the upper end of theframe leg 38 and located forwardly of the leg relative to the seat 23a. Extending laterally from opposite sides of the lower end of thebar 66 are two shafts 68 (only one shaft visible) mounting generally cylindrical leg cushions orpads 70. The chest and shoulder press exercises and the leg extension exercise will be explained presently.

The pectoralfly exercise arms 18 are pivotally mounted on asupport 72 rigidly attached to the left handupright frame member 26 in FIG. 1.Support 72 comprises abar 74 extending horizontally out from and rigidly secured to theframe member 26 and ahorizontal cross bar 76 rigid on the outer end of thebar 74. The pectoralfly exercise arms 18 comprisevertical bars 78 having inclined upper ends 80. These upper right angle ends 80 of thebars 78 are pivotally connected at 82 to opposite ends of thesupport bar 76 for rotation of thepectoral fly arms 18 on vertical axis laterally offset from the arms. Mounted on the fly arms are cushions orpaths 84, and rigid on the upper ends of the arms are curved cable guides 86 concentric with the pivot axes of the arms.

The pectoralfly exercise seat 50 comprises a seat member 88 and a backrest 90 mounted on theupright frame member 26 below the pectoralfly exercise arms 18. The pectoral fly exercise using these arms will be explained presently.

Weight stack 20 comprises a multiplicity of relatively flat,individual weights 92 placed one on top of the other and a top coupling weight 94 at the top of the stack. Means 94a are provided for selectively coupling any number of theindividual weights 92 to the top of coupling weight 94 to form an effective exercise weight stack 20a.Weight stack 20 is supported onvertical rods 95 attached to theframe 12 for vertical movement relative to the frame.

As mentioned earlier, an important feature of the invention resides in the fact that all of the exercises which are performed on the present exercise apparatus utilize the one weight stack 20 (actually the effective weight stack 20a) to provide a resisting force for the exercises. To this end, the cable means 22 for selectively connecting the weight stack to the

exercise members

14, 16, 18 and to the user in FIGS. 6, 7, and 8 comprises acable 96 attached at one end to the top coupling weight 94 of theweight stack 20. Means are provided for selectively and releasably connecting the other end of this weight stack cable to the

exercise members

14, 16, 18 and to the user in FIGS. 6, 7 and 8. In the particular exercise apparatus disclosed, this latter means comprises the structural elements described below.

On the latter end of theweight stack cable 96 is acoupling member 98, such as a snap hook. When performing the chest press exercise of FIG. 1, this coupling member or hook is attached to amating coupling member 100, such as a ring, on the lower end of one press bar handle 48. When performing the shoulder press exercise of FIG. 2, thecable coupling member 98 is attached by achain 102 to the pressbar coupling member 100. This chain serves merely to extend the effective length of the weight stack cable 90.

When performing a leg extension exercise, theweight stack cable 96 is attached to acoupling member 104, such as a bolt, on theleg extension arm 16. This ring is located between the upper pivot axis of the arm and itslower leg pads 70.

When performing a pectoral fly exercise, theweight stack cable 96 is attached tocables 106 secured to the pectoralfly exercise arms 18. One end of thecables 106 extend about and are secured at their extreme ends to the curved cable guides 86 of thepectoral fly arms 18. The opposite ends of thefly arm cables 106 are attached to a coupling member 108, such as a ring, adapted for releasable engagement with the weight stack cable coupling member orspring link 98.

Theweight stack cable 96 is supported and guided by

pulleys

110 and 112 on theapparatus frame 12.Pulley 110 is an upper pulley which is mounted on the upper end of theframe 12 above theweight stack 20.Pulley 112 is a lower pulley which is adjustable or movable between its position of FIGS. 1, 4 and its positions of FIGS. 5 through 9. To this end, thepulley 112 is rotatably supported between the arms of a yoke shapedbracket 114 having a bearing 115 at its closed end. Mounted on theupright frame member 26 adjacent the pectoralfly exercise seat 23b is apulley mounting bracket 116. This pulley mounting bracket has upper andlower arms 118 for receiving therebetween the closed end of thepulley bracket 114. A coupling/pivot pin 120 is insertable through holes in these arms and the pulley bracket bearing 115 to pivotally mount thepulley 112 on theframe member 26 in the position of FIGS. 1 and 4, with the pulley bracket pivot axis generally vertical. A secondpulley mounting bracket 122 is attached to thelower frame bar 26 for pivotally mounting thepulley 112 in its position of FIGS. 5 through 9.

The manner in which theexercise apparatus 10 is used will now be explained.

When performing the shoulder press exercise of FIG. 1, theweight stack cable 96 is attached to the coupling member orring 100. Theadjustable cable pulley 112 is mounted in its position of FIG. 1, on theupright frame member 26. Thebackrest 52 of the seat 23a is placed in its upright position of FIG. 3A, against theupright frame member 24. The user sits on the seat 23a, with his upper body against thebackrest 52, and hence in an upright position, and grips the press arm handles 46. The user then moves thepress arm 14 back and forth against the resistance of the effective weight stack 20a.

It is significant to note here that thepulley 112, when mounted in its position of FIG. 1, is offset to one side of the user so that theweight stack cable 96 extends to one side of the user and thus does not obstruct the movements of the user during the chest press exercise.

When performing the incline shoulder press exercise of FIG. 2, thebackrest 52 of the seat 23a is adjusted to a forwardly inclined position, as shown in FIG. 2, and theweight stack cable 96 is attached, by thechain 102, to thepress arm 14. The user sits on the seat 23a with his upper body against thebackrest 52 and hence disposed in an forwardly inclined attitude. The user grips the press arm handles 46 or 48 and moves thepress arm 14 back and forth against the resistance of the effective weight stack 20a, in somewhat the same manner as in the chest press exercise of FIG. 1.

When performing the leg extension exercise of FIG. 10, thepress arm 14 is secured in a rearward position behind the seat 23a. Thebackrest 52 of this seat is adjusted to its upright position. The loweradjustable cable pulley 112 is placed in its position of FIG. 5 and theweight stack cable 96 is extended around apulley 124 on thelower frame bar 36 and connected to the coupling member or bolt 104 threaded into legextension exercise arm 16. The user sits on the seat 23a, in the same position as shown in FIG. 1, and engages the lower ends of his legs with the rear sides of the legextension arm pads 70. The user then flexes his legs and knees to rotate the legextension exercise arm 16 back and forth against the resistance of the effective weight stack 20a.

When performing the pectoral fly exercise of FIG. 9, theweight stack cable 96 is attached to the coupling member or ring 108 on thefly arm cables 106, as shown in FIG. 10. The loweradjustable pulley 112 is left in its position of FIG. 5. The user sits on theseat 23b with his forearms pressing against thepads 84 of thefly arms 18 and with his hands gripping these arms, as shown in FIG. 9. The user then rotates these arms about theirpivots 82 and against the resisting force of the effective weight stack 20a.

It is significant to note here that in the chest and shoulder press exercises of FIGS. 1 and 2, it is necessary to mount the loweradjustable cable pulley 112 in its offset position of FIGS. 1, 2 and 4 in order to locate theweight stack cable 96 at one side of the user and thereby prevent the cable from obstructing the user's movements during the chest and shoulder press exercises. This requirement does not exist in the pectoral fly and leg extension exercises of FIGS. 9 and 10. Accordingly, in these latter exercises, theadjustable pulley 112 may be mounted in its position of FIGS. 5 and 9 wherein the pulley is optimally located for attachment of theweight stack cable 96 to both the legextension exercise arm 16 and the pectoral flyexercise arm cables 106.

The loweradjustable pulley 112 is also mounted in its position of FIG. 5 when performing the leg and arm exercises of FIGS. 6 through 8. Performing the arm exercises of FIGS. 6 and 7, theweight stack cable 96 is attached to a cross bar handle 126 to be held by the user. The user flexes his arms at the elbows to move thecable 96 back and forth against the resisting force of the effective weight stack 20a. In FIG. 8, theweight stack cable 96 is attached to a band 128 which is placed about the user's ankle. The user moves his leg back and forth against the resistance of the effective weight stack 20a.

Obviously, other exercises maybe performed using the exercise apparatus described above.
