Description

July 25, 1967 1. 1. RAND PHYSICAL CONDITIONING TREADMILL APPARATUS lFiled March 18, 1965 INVENTOR J. Rond MZ 4Q/5X ATTORNEY Fig. 2

United States Patent 3,332,683 PHYSICAL CONDITIONING TREADMILL APPARATUS Jimmy J. Rand, Rte. 1, Box 223, Groesbeek, Tex. 76642 Filed Mar. 18, 1965, Ser. No. 440,734 6 Claims. (Cl. 273-55) The present invention relates to physical conditioning apparatus and more particularly to physical conditioning apparatus of a treadmill type. The apparatus provided by `the present invention is especially useful -in the development of fundamental skills in football and is also beneficial in any physical conditioning program.

The popularity of football as a spectator sport has in creased to very high levels in recent years. The sport is played by participants over a wide range of ages and competition between teams is quite high. Since football is an extremely rigorous contact sport, it is very important that the participants be in excellent physical condition in order that they can play to their maximum physical ability as well as prevent physical injury.

The present invention provides physical conditioning apparatus which can be utilized as a year round training and conditioning machine for athletes. Moreover, the apparatus of the present invention can be used as an excellent aid in teaching an athlete to assume the proper stance, weight distribution and leg action as would be used in blocking, tackling and ball carrying.

In accordance with the present invention, a continuous rubber belt moves across two spaced apart rollers. Two vertically disposed body resistors which are individually adjustable horizontally zare positioned slightly in front of the belt. A friction brake is also provided for controlling the force required to move the belt. In Operating the device, pressure is applied by the individual against the body resistor. The body resistor acts as resistance or opposing force which creates thrust or driving power by the individuals leg action upon the belt. The amount of work output by the individual is controlled by the brake. When the brake is released, the belt will move quite freely and the work required to run on the device will be comparable to any sprint or dash.

Features of the invention which are believed novel are set forth with greater particularity in the appended claims. Many objects and advantages of the invention will, however, become apparent to those skilled in the art as the following detailed description of the preferred embodiment of the invention unfolds when taken in conjunction with the appended drawings in which like reference numerals denote like parts and in which:

FIGURE 1 is a side elevation view of the preferred embodiment of the physical conditioning apparatus provided by the present invention;

FIGURE 2 is a front elevation view of the apparatus provided by the present invention;

FIGURE 3 is a rear elevation view with the body resistors of the present invention in one position;

FIGURE 4 is a rear elevation view showing the body resistons in a different position;

FIGURE 5 is an enlarged side elevation view illustrating the manner in which tension of the belt can be adjusted; and

3,332,683 Patented. July 25, 1967 ICC' FIGURE 6 is `a view taken along line 6-6 of FIGURE 1 illustrating the braking device of the present invention in somewhat greater detail.

Turning now to the drawings, it can be seen that there is provided a frame, designated generally by the reference numeral 10, which consists of two elongated runners 12 and 14 which are suitably formed of heavy gauge steel and are of channel configuration. Two horizontally disposed channel members 16 and 18 extend between members 12 and 14 for holding members 12 and 14 in spaced apart parallel' relation. Members 16 and 18 are suitably attached to members 12 and 14 by welding.

As best seen in FIGURE 6 of the drawings, each of the members 12 and 14 are of generally channel configuration a-nd include a web portion 20, a tirst leg portion 22 and a second leg portion 24. The second leg portion 24 is elongated and bent inwardly at 26 and outwardly at 28. The outwardly extending portion 28 suitablyy bears against the upper side of the channels 16 yand 18, as shown. The ends of each of the channels suitably slant upwardly from the bottom leg 22 as show-n in FIGURE 1 and runners 30 and 32 are suitably provided over the ends for purposes of covering any edges which may be present and facilitating sliding of the apparatus across a surface.

A iirst pair of pillow block bearings 40 are mounted to channel members 12 and 14, suitably by screws 42 and nuts 44 as shown in FIGURE 6. A shaft 46 extends between the pair of bearings 40 and is journalled for rotation therein. The shaft 46 suitably extends past one of the bearings 40 as indicated at 48 of FIGURE 6, and a pulley 50 having a groove 51 formed in its periphery is mounted on the shaft 46 for rotation therewith. Also mounted on the shaft 46 is a roller 52. Roller 52 is suitably of greater diameter at itsvcenter portion than `at its ends 56. It will also be noticed that the periphery of the roller 52 extends below the upper edge of the channels 12 and 14 and faces the inwardly extending shoulder 26.

A pair of upright channel members 60 and 62 are connected at their lower ends to the front of the channels 12 and 14, respectively, suitably by welding. A iirst horizontally disposed rod 64 is connected to `and extends between the upright members 60 and 62 at their upper extremity. A second horizontally disposed rod 62 also extends between theupright members 60 and 62, the rod 66 being substantially lower than the rod 64.

Two body resistors and 72 are also provided. In the form shown, the body resistors 70 and 72 each include a ilat elongated member 74 which is attached to the cross bars 64 and 66, suitably by clips 76. By loosening the .clips 76, the position of the body resistor along the cross bars 64 and 66 can be adjusted horizontally. A pad 78, suitably of rubber cushion, is attached to the upper portion of the body resistors 70 and 72 as shown in FIGURE 1. The pad 78 is covered and held to the member 74 by a layer 80 of expanded vinyl or similar material.

Extending rearwardly from the upright member 60 and connected thereto, suitably by welding is a brake support 90. A brake arm 92 is pivotally attached to the support at point 94. The brake arm 92 suitably includes a plurality of notches 96 formed along its upper edge at graduated positions. A weight 98 is also provided. The weight 98 is suitably of conventional type having a slot 100 formed therein whereby the weight 98 can move along the brake arm k92 and includes an edge portion for engaging the notches 96 to hold the weight in a desired position. A block 102 of wood or similar material is also provided, the lower edge 104 of the block 102 being arranged in a V-conguration which conforms to the groove 51 of the pulley 50. The block 102 is mounted to the brake handle 92, suitably by screw 106 and nut 108 in a position such that the lower edge 104 of the block 102 will engage the groove 51 of the pulley 50.

As best shown in FIGURE of the drawings, the upper edge of the members 12 and 14 are each slotted at 110 and 112. A pair of L-shaped brackets 1,14 and a second pair of pillow block bearings 116 are also provided. Bearings 116 and brackets 114 are each connected to the channel members 12 and 14 by bolts 118 and nuts 120 as shown, with the bearings resting on the Y horizontally disposed portion of brackets 114. Each of the runners 32 extend above the upper surface of the channels 12 and 14 at 122 and has an aperture 124 formed therein. A stud 126 is connected at one end to the L- shaped bracket 114, with the stud extending through the aperture 124. A second shaft 130 extends between the pair of bearings 116, and is journalled for rotation therein. A second roller 132 is connected to the shaft 130, in the manner described previously with regard to shaft 48 and roller 52.

A continuous belt 140 is also provided. Belt 140 er1- circles the two rollers 52 and 132. The tension of the belt 140 can be adjusted by adjusting the position of the bearings 116 in which the shaft 130 is journalled for rotation. This can suitably be accomplished by loosening the nuts 120, permitting the bolts 118 to move in the slots 110 and 112 and adjusting the nuts 144 to cause the bearings 116 to be pulled toward portion 122 of the skid member 32. In this regard, it will be noted that it isimportant that provision be made for adjusting the tension of the belts since under use, they will normally stretch to some extent. If the belts are too tight, it will be extremely diiiicult to cause the belt to move, and if the belt is too loose, it will sag to such an extent that the athlete utilizing the apparatus cannot properly maintain his balance.

In operation ofthe apparatus, body resistors 70 and 72 are positioned in accordance with the training desired. Thus, if it is desired to teach the proper stance, weight distribution and leg action for blocking and tackling, the body resistors would suitably be adjusted to the position shown in FIGURE 3, in which event only the left shoulder of the athlete would bear against the body re-V sistors. As mentioned previously, the body resistors act as a resistance or opposing force which creates thrust or driving power by the individuals leg action upon the belt. The belt will start turning and continue to turn as long as there is driving force by the legs on the belt.

It will be noted that the brake is positioned at a point that will be convenient for either the athlete to vary the position of the weight 98 or for the coach or trainer to do so. The position of the Weight along the handle 92 determines the amount of force with which the wooden block 102 bears against the pulley 50, therebycontrolling the amount of work required by the athlete to cause the belt to move. The position of the body resistors 70 and 72 would be moved to the extreme right position, of course, if it were desired to utilize the right shoulder `of the athlete in the blocking or tackling exercise.

If the apparatus is to be used only for conditioning, it is practical to separate the body resistors 70 and 72 to the extreme position shown in FIGURE 4, which position is practical for two athletes to utilize the apparatus simultaneosuly. In other instances, it is practical to lmove both the body resistors 70 and 72 toward the center position from that shown in FIGURE 4 such that the space betweenV the body resistors 70 and 72 will only be suicient to permit the athletes head to pass therethrough with both shoulders bearing against one of the body resistors.

As mentioned previously, the rollers S2 and 132 are each suitably of a greater diameter at its center portion than at its end portions. The belt will therefore tend to move toward the center of the rollers rather than toward the ends as the belt moves and the rollers turn. Moreover, if the belt 140 should move toward one of the ends, the distance it can move is limited by the presence of the inwardly turned portion 26 of the channels 12 and 14. Further, the outwardly extending portion 28 of the channels 12 and 14 provide a track for the belt to support the belt when it is being installed and to prevent the edge of the belt rubbing against a sharp edge and producing undue wear.

Although the invention has only been described with reference to a particular preferred embodiment thereof, many changes Vand modications will become Vapparent to those skilled in the art in view of the foregoing description. The foregoing description is therefore intended to be illustrative and not limiting of the invention dened in the appended claims.
