APOSTOL MUSCLE EXERCISING APPARATUS 2 Sheets-Sheet 2 Filed Jan. 9, 1961 INVENTOR. CHRIS J. APOSTOKL %M ATTORNEYS United States Patent 3,120,954 MUSCLE EXERCISING APPARATUS Chris J. Apostol, 340 East 4380 North, Provo, Utah Filed Jan. 9, 1961, Ser. No. 81,333 11 Claims. (Cl. 272F553) This invention relates to apparatus of the type designed to provide planned exercise for various muscles of the human body.

Apparatus of this type has been developed heretofore for use primarily in the field of physical therapy to provide corrective exercises for persons suffering from certain kinds of physical incapacity.

The present invention is particularly concerned with the training of athletic squads, for example football players, and has great utility for this purpose in the athletic programs of schools and other institutions.

Principal objects of the invention are to provide for the exercise of all major muscle groups of the lower limbs, and to do this effectively for an entire squad at once by means of a single apparatus having a plurality of exercising stations.

Outstanding features in the accomplishment of these objects are the provision of a table having multiple exercising stations, for individual athletes, arranged side-byside about the peripheral margins of its top, and the provision at each station of muscle exercising mechanism uniquely adapted for exercising various muscles of the low er limbs and for adjustment to fit individuals of different sizes. A raised pad disposed marginally of the table top places the legs of an individual, seated on the table, in proper position for most effective exercise.

A specific embodiment representing what is presently regarded as the best mode of carrying out the invention is illustrated in the accompanying drawings.

In the drawings:

FIG. 1 represents a top perspective view of muscle exercising apparatus for an athletic squad in accordance with the invention;

FIG. 2, a top plan view of the apparatus of FIG. 1;

FIG. 3, a fragmentary vertical section taken on the line 33 of FIG. 2. and drawn to a considerably enlarged scale;

FIG. 4, a similar view but taken on the line 4-4 of FIG. 2;

FIG. 5, a fragmentary front elevation taken on the line 5-5 of FIG. 4;

FIG. 6, a view corresponding to that of FIG. 3 but drawn to a much reduced scale and indicating schematically how the apparatus is used for exercising the quadricep muscles and how the femur bone is held parallel with the table top by means of the marginal pad;

FIG. 7, a similar view showing how the apparatus is used for exercising the calf muscles;

FIG. 8, another similar view showing how the apparatus is used for foot flexion;

FIG. 9, a view corresponding to that of FIG. 4 but drawn to the reduced scale of FIGS. 6-8 and showing how the apparatus is used for exercising the biceps femoris, commonly known as the hamstring; and

FIG. 10, still another similar view showing how the apparatus is used for exercising neck muscles.

Referring to the drawings:

In the form illustrated, the apparatus of the invention comprises an elongate, rectangular table 12 having a top surface 12a adapted to seat, about its peripheral margins, a group of athletes for planned exercise. In the present instance, the table seats siX and is sufliciently long to accommodate a user reclining lengthwise of the table with his legs or head projecting from one end.

Spaced about the lateral sides and ends of the table and secured thereto are muscle exercising mechanisms, which, collectively, provide multiple stations 13 for the several individuals making up the group of athletes.

Both of these mechanisms comprises a pair of mutually spaced brackets '14 secured to the table 12 along a margin thereof and projecting outwardly therefrom in order to space the working parts of the mechanism away from the side of the table sufficiently far to accommodate the legs of the user hanging over the edge of the table, see FIGS. 6 and 8. Pivotally attached to the brackets 14, respectively, as by means of pivot pins 15, are a pair of arms 16, which hang downwardly and swing about a horizontal axis that passes through the pivot pins and extends along the table. As so arranged, arms 16 can be swung upwardly and outwardly of the table.

Secured to and interconnecting the lower ends of arms 16 is a weight carrier in the form of a shaft 17, which extends parallel with the aforementioned pivot axis and mounts a padded roller 18 between the arms. Shaft 17 projects beyond arms 16 for the reception of one or more weights 19, FIG. 2, of selected value. Roller 18 is adapted for engagement by the feet of a user of the apparatus, as in FfGS. 6' and 8.

It is preferred that the connection of the Weight carrier to the arms be adjustable lengthwise of such arms, so as to make possible adaptation of the mechanism to various individuals. For this purpose, it is a feature of the invention that disks it} are employed, these being rotatably attached at their centers to the lower ends of arms 16, respectively, and shaft 17 being carried by such disks. As shown, shaft 17 extends through roller 18 and aligned receiving openings provided in the circumferential margins of disks 20 and is secured against displacement longitudinally by means of collars 21 anchored in any suitable manner, as by set screws (not shown). Its position relative to the lengths of the arms 16 can be varied by rotating such disks relative to the arms and locking them in any desired position, see the diverse position shown in FIGS. 1 and 2. For locking purposes, disks 20 are provided with respective circumferential series of holes 22 and arms 16 are provided with registering holes, respectively, for the reception of locking pins 23.

With the exercising mechanisms so constructed, the individuals sit at the respective stations 13 on the table 12 with their legs dangling over the edge. Their feet engage the padded rollers 13 as indicated in FIGS. 6 and 8 and exercise of the quadriceps proceeds with the raising and lowering of the weighted arms in the manner indicated by dotted lines.

A feature of the invention is the provision of a raised pad about the peripheral margins of the table, so that the femur bones of the legs of the individuals exercising are held substantially parallel with the top of the table, as indicated in FIG. 6. This makes for more rigorous exercise and also gives bracing support to the legs during the exercise. As illustrated, elongated pads 24, made up of any suitable material, are placed along the edges of the table 12 marginally of the seating surface 120. Each pad gradually slopes downwardly and inwardly of the surface from a ridge 24a extending lengthwise of the pad and marginally of the table. The ridge is preferably rounded forwardly as shown, so as to comfortably support the legs of the users of the apparatus during the exercise.

The exercising mechanisms are preferably adapted for various exercises, for example, that shown in FIG. 7 intended to develop muscles of the calf. For this purpose, opposite ends 18a of the padded rollers 18 are reduced in diameter, so that they may be easily grasped by the hands of users of the apparatus and manipulated in the manner indicated in FIG. 7.

The dorsal foot flexion exercise indicated in FIG. 8 is carried out from a sitting position with the locking pins 23 removed, so that adjustment disks are free to rotate. The provision for this exercise along with the other exercises possible with this apparatus constitutues a significant and important feature of the exercising mechanism of this invention. While the pad is helpful for the proper execution of this exercise, it is not nearly so important as it is in connection with the quadriceps exercise previously described and may be satisfactorily carried out whether or not the table is padded marginally.

For the purpose of exercising the biceps femoris or socalled hamstring muscles of the legs, and also muscles of the neck when desired, the exercising mechanisms at the end stations 13 are augmented by the provision of auxiliary arms and rollers, which are used from reclining positions on the table 12.

As illustrated, a second pair of arms is provided at and extending angularly outwardly from the pivot ends of the arms 16, respectively, of these end mechanisms. They extend preferably at a 90 angle or thereabouts and, together with the arms :16, form bell cranks. The free ends of these arms 25 are interconnected by rollers 26, which are also parallel to the pivot axis and, thus, to the rollers 18.

In carrying out the leg and neck exercises of FIGS. 9 and 10, respectively, the roller 26- is the one which is en gaged by the legs and neck of the user of the apparatus, as shown. Adjustment of position of weighbcarrying shaft 17 relative to the outer circumferential margins of disks 20*, as previously explained, shortens or lengthens bell crank arms 16 and thereby provides a way of c ranging the effective value of the weights utilized. For these exercises, it is preferred that the end pads 24 be removed, and, to this end, they are preferably made separable from the table top While the side pads 24 are preferably permanently fastened to such table top.

While a seating and reclining structure accommodating a group of individual users is illustrated, it should be realized that a structure accommodating only one individual and having only a single exercising station can be constructed if desired. Moreover, while the marginal padding represents an important part of the invention in connection with the quadriceps exercise, it may be dispensed with in connection with the other exercises.

Whereas there is here illustrated and described a certain prefererd construction of apparatus which I presently regard as the best mode of carrying out my invention, it should be understood that various changes may be made withoutdeparting from the inventive concepts particularly pointed out and distinctly claimed herebelow.
