  • FIG. 9 is a perspective view of a third modified form of the subject exercising device, illustrating the manner in which the rope is wrapped around the frame in order to adjust the amount of tension in the device.
  • FIG. 10 is a perspective view of the exercising device and floorboard of FIG. 1, shown used with a shoulder harness of the type used by basketball players.
  • the numeral 10 indicates generally the preferred form of an adjustable exercising device embodying the teachings of the present invention, provided with a length of rope 12 which has a two-handed handle 14 removably attached at each end thereof, and which is used in combination with a floorboard 16 by an athlete A.
  • the exercising device 10 includes a frame which is preferably cast from a lightweight, noncorrosive metal such as aluminum, and which is of generally U-shaped configuration with opposed elongated, cylindrical leg portions 18 which have smooth outer surfaces and which are of a length to receive several turns of the rope therearound, and which are interconnected at one set of ends by a curved portion 20.
  • a cross-wise extending cylindrical retaining bar portion 22 with a smooth outer surface which is preferably cast integral with the leg portions 18.
  • the retaining bar portion is preferably straight, or at least not concave on the inside so that the portions of rope 12 are not caused to move together and rub, as will be discussed more fully hereinafter.
  • a rigid guide-bar portion 24 extends cross-wise between the leg portions 18 adjacent the curved end portion 20 to provide a hook-receiving eye 26 therebetween, for a purpose to appear.
  • the guide-bar portion 24 is also preferably cast integral with the leg portions 18.
  • each of which has a short cylindrical roller 30 with a concave face 32 rotatably mounted thereon.
  • the shafts 28 and rollers 30 can be replaced by opposed short studs 30a as shown in the first modified construction (FIG. and 130a in the second modified construction (FIGS. 6 and 7), which studs are preferably cast integral with the guidebar portion 24.
  • the guard roller 34 Parallel with the retaining-bar portion 22 and spaced therefrom is an elongated cylindrical guard roller 34 (FIGS. 2 and 3) with two spaced apart shallow grooves 36 in the outer surface thereof, which guard roller is rotatably mounted on pins 38 threadedly fastened in apertures 40 formed in the leg portions 18.
  • the guard roller 34 and its supporting pins 38 can be replaced by a cylindrical guard-bar 34a as shown in FIG. 5.
  • the guard-bar 34a is also preferably formed integral with the leg portions 18.
  • one method of using the exercising device 10 is with a floorboard 16 which is preferably made from plywood and of rectangular configuration and large enough so that the athlete A can stand on it. Fastened .to the center of the board 16 and projecting upwardly therefrom, is a hook 42, which is adapted to extend through the eye 26 (FIG. 2).
  • the center portion of the rope 12 is doubled back upon itself to form a loop or bight and the loop first inserted between the retainingbar portion 22 and the guard-bar 34a (FIG. 5).
  • the loop is then enlarged and passed over the curved portion 20 of the frame as shown by the broken lines in FIG. 5, then passed through the opening between the guard-bar 34a and the guide-bar 24, and this sequence repeated to provide the desired number of turns of rope 12 on each leg portion 18.
  • the loop of the rope 12 is dropped onto one of the short studs 30a. The result is illustrated in FIG. 2, the only difference being that in FIG. 2, the bight of the rope is inserted between the retaining bar and the guard roller 34, and the end of the loop is positioned on one of the short cylindrical rollers 30.
  • the number of turns of rope 12 around each leg portion 18 determines the amount of force which is required to move the rope through the device, and therefore the amount of exercise which results.
  • one method of using the adjustable exercising device 10 is with the floorboard 16 shown in FIG. 1.
  • the athlete A first grasps one of the handles 14 with both hands while in a crouch position with head up and arms straight, and with the hands slightly below knee level.
  • the portion of the rope attached to the other handle which will be referred to as the trailing portion, is grasped with the fingers of one hand at the handle so that the athlete A, in effect, is grasping both portions of the rope 12 which are connected to the exercising device.
  • the trailing portion of the rope 12 is dropped, and the handle 14 pulled upwardly to a position under the chin, as shown in FIG. 1.
  • the trailing portion of the rope 12 rides over the guard roller 34 in one of the shallow grooves 36 so as to maintain the turns of rope around the adjacent leg portion 18 in spaced apart relationship.
  • the guard roller 34 prevents the turns of rope 12 from piling up, one on top of the other, above the guide-bar portion 24 when the trailing portion of the rope is dropped or cast aside.
  • the athlete A rotates the handle 14 and pushes it upwardly above his head, at the esame'time going up on his toes.
  • FIG. 10 Another method of using the subject exercising device is illustrated in FIG. 10 in which the adjustable exercising device 10 and the floorboard 16 are used with a shoulder harness 52 fastened to one end of a rope 54.
  • This accessory is particularly useful to basketball players in helping to develop their leg muscles for jumping purposes.
  • the athlete inserts his arms through the two loops of the shoulder harness and the free end of the rope 54 is pulled through the exerciser 10 until the athlete is in a crouch position with knees bent and shoulders back and head up. With the exerciser adjusted to the proper resistance the athlete presses with his legs to reach the standing position. The athlete can hold the free or trailing end of the rope or it can be held by the coach who can thereby cause an initial high resistance, followed by a lesser resistance.
  • One outstanding advantage of the subject exercising device is the ease and speed with which ropes with different accessories attached thereto can be interchanged.
  • the athlete can start out with the rope 12 and two-handed handles as shown in FIG. 1 and easily change over to the shoulder harness 52 and the rope 54.
  • the athlete merely removes the loop of the rope 12 from engagement with the short cylindrical roller 30 (FIG. 2), passes the loop over the curved portion 20 of the frame, and pulls on both portions of the rope adjacent the retaining bar 22 to strip the turns of rope oif of the leg portions 18 and through the space between the retaining bar 22 and the guard roller 34.
  • the form of exercising device illustrated in FIG. 5 is substantially the same as that shown in FIG. 2 except that the FIG. 5 version has a fixed guard bar 34a in place of the rotatable guard roller 34, and the studs 30a are used instead of the rollers 30.
  • fixed members are used in place of rotatable members.
  • FIGS. 6 and 7 What I refer to as the second modified form of the adjustable exercising device, shown in FIGS. 6 and 7, is very similar to the form illustrated in FIG. 5 except that the guard bar 34a has been omitted.
  • the parts or portions of the second modified device shown in FIG. 6 which are similar to the parts or portions of the device shown in FIGS. 2 and 5, are indicated by a like numeral increased by 100; thus, the leg portions 18 become theleg portions 118.
  • the guard roller 34 (FIG. 2) or the guard bar 34:: (FIG. 5) of the preferred constructions prevent the trailing portion of the rope from piling up on one of the leg portions during the execution of the exercise illustrated in FIG. 1. Accordingly, inasmuch as the second modified form of exercising device 110 does not have this guard roller or bar, it is not quite as satisfactory as the construction first described when used in executing the exercise illustrated in FIG. 1.
  • FIG. 1 the adjustable exercising device is shown used with the fioor board 16.
  • FIG. 6 the second modified exercising device 110 is shown used with a hook 142 which is fastened to a wall 44 or the like.
  • FIG. 8 it illustrates the second modified device 110 having a strap 46 looped through the eye 126, said strap including a metal ring 48 at one end thereof and a doubled-back portion 50 at the other end.
  • the doubled-back end 50 is inserted between the top or side of a door and the doorframe adjacent thereto, and the door maintained in the closed position.
  • the preferred form of the exercising device 10' (FIG. 1) was described as being used with a length of rope 12 having two-handed handles 14 removably attached to each end thereof.
  • the preferred form of device, as well as the various modified forms being described, can a so be used with single-handed handles 114 (FIG. 8), with the athlete grasping one handle in each hand and pulling on them alternately in the manner illustrated by the arrows in FIG. 8.
  • FIG 9. A further modified form of the subject adjustable exercising device which I refer to as the third modified form 210, is illustrated in FIG 9.
  • the parts and portions thereof which are similar to the parts and portions of the preferred form illustrated in FIG. 2, are identified by like numerals with 200 added thereto; thus, the leg portions 18 become the leg portions 218-
  • the third modified form of exercising device 210 (FIG. 9) resembles the second modified form 110 (FIG. 6) to the extent that the guard bar 34a of FIG. 5 has been omitted.
  • the studs 130a (FIG. 6) have been omitted and the guidebar portion 124 changed to an arcuate configuration to provide an inner annular portion 224a (FIG. 9) which rounds Off the eye 226 for receiving the length of rope.
  • This third modified form of exercising device can also be produced in a single casting operation without machining and without using cores.
  • each handle 114 is merely passed through the center opening of the frame the desired number of times in the manner illustrated by the arrows in FIG. 9.
  • each leg portion 118 of the second modified form of the device 110 can be adjusted in like manner, i.e., by inserting either the handle 14 or the handle 114 (depending upon which is being used) through the center opening in the frame. Accordingly, the second modified form of device 110 (FIGS. 6 and 8) has the advantage that it can be easily and quickly adjusted in either of two different ways.
