Pruitt, Sr., Gainesville, Ga., assignor, by court order, to Frances R. Pruitt Filed Apr. 25, 1963, Ser. No. 275,600 4 Claims. (Cl. 272-33) This invention relates to exercising devices and more particularly to an exercising. device which provides exercise for all muscles of a persons body without tedium or boredom by utilizing the persons efiorts to change or maintain his position in space.
Past interest in physical fitness and in the mental and physical health resulting from proper exercise has resulted in a variety of previous exercising devices. Most of these previous exercising devices exercise only one group of muscles at a time and only under conditions which are tedious and boring to the person using the device.
The exercising device described herein utilizes a persons efforts to change or maintain his position in space and the resulting muscular tensions and relaxations to provide exercise for all muscles of the persons body under conditions which are entertaining and which present a challenge to the person. The tedious and repetitious counting of exercise motions is completely eliminated and all muscles of the persons body are properly exercised without the individual having to follow any elaborate program of planned exercise. Overdevelopment of certain muscles is avoided and muscular coordination is improved rather than inhibited.
The invention positions a person desiring exercise in space so that a tilting of his body or other shifting of his weight will change his position. The efforts of the person to change his position in this manner and to return himself to his original position in a similar manner will, after a short time, have exercised every muscle in the persons body. The invention is a gimbal arrangement comprising an outer frame freely rotatable about an axis and an inner frame freely rotatable within the outer frame about an axis perpendicular to the axis of the outer frame.
The person desiring exercise positions himself in the inner frame with his center of gravity more or less in that location at which the axis of rotation of the inner frame intersects the axis of rotation of the outer frame. Thus, if the individual shifts his weight he will rotate with the inner frame about the axis of rotation of the outer frame, the axis of rotation of the inner frame, or both the axis of rotation of the outer frame and the axis of rotation of the inner frame. This shifting of weight for rotation will cause the tensing of certain muscles in the persons body and the relaxing of other muscles. Moreover, once the persons position in space has been changed, his efforts to return to his original position will tense and relax still other muscles. After a short period of practice with the exercising device herein described, a person desiring exercise or entertainment soon acquires the skill to accomplish interesting and entertaining manuevers in the exercising device and will, almost without conscious effort, exercise all the muscles of his body.
These and other features and advantages of the invention will be more clearly understood from the following detailed description and the accompanying drawings in which like characters of reference designate corresponding parts in all figures and in which:
FIG. 1 is a perspective view of the exercising device showing the orientation of the outer frame and of the inner frame when a person using the device has tilted himself backwards and to his right by appropriately shifting his weight.
FIG. 2 is a side elevational view of the exercising'device showing the outer frame in its neutral or horizontal position and the inner frame in its neutral or vertical position.
FIG. 3 is a top plane view of the exercising device with the outer frame and the inner frame oriented as in FIG. 2.
FIG. 4 is a side elevational view of the inner frame of the exercising device showing in solid outline a person positioned for minimum sensitivity of the exercising device and in dashed outline a person positioned for maximum sensitivity of the exercising device.
The figures and the following detailed description disclose the preferred specific embodiment of the invention, but the invention is not limited to the details disclosed since it may be embodied in other forms.
The invention is best understood by considering it as comprising an outer frame 10 positioned between a triangular support 211 and a triangular support 12 and freely rotatable about an axis of rotation extending between the support '11 and the support 12 and of an inner frame 13 positioned within the outer frame 10 and freely rotatable about an axis of rota-tion perpendicular to the axis of ro tation of the outer frame 10. A spacing bar \14 extends between one corner '15 of the support 11 and the corresponding corner 16 of the support 12 and a spacing bar 17 extends between a second corner 18 of the support 1 1 and the corresponding corner 19 of support 12. These spacing bars 14 and 17 and the side 20 of the support 11 between corners 15 and I S and the side 21 of support 12 between corners 16 and 19 form a rectangular base above which the support. 11 and the support 12 extend in a direction generally perpendicular to the plane of the base. This places the third corner 23 of the support 11 and the third corner 24 of the support 12 well above the ground or floor on which the base is resting, and it is between the cornerv 23 of the support 11 and the corner 24 of the support 12 that the outer frame 10 is mounted.
In the specific embodiment of the invention described herein, the outer frame 10 is a tube of steel or similar material formed into a rectangle. A pin 25 extends from one side 26 of the outer frame 10 into a sleeve 27 fixedly attached to the corner 23 of support 1 1 and a pin 28 extends from the opposite side 29 of the outer frame into a sleeve 30 fixedly attached to the corner 24 of the support 12. The pins 25 and 28 are freely rotatable in the sleeves 27 and 30 and have axes of rotation which coincide and which result in the outer frame 10 being freely rotatable about an axis of rotation coinciding with their axes of rotation.
The pin 25 is positioned along the length of the side 26 of the outer frame 10 and the pin 28 is positioned along the length of the side 29 of the outer frame 10 so that the weight of the outer frame 10 is balanced about its axis of rotation and will not tend to rotate because of its own weight.
In order to securely position the pins 25 and 28 in the sleeves 27 and 30, the support 11 has a guy member 31 extending outwardly of the outer frame 10 from corner 23 to a support point on the ground or floor formed by the intersection of a floor member 32 extending from the cor-,
ner 15 of the support 11 and a floor member 33 extending from the corner 18 of the support 11, and the support 12 has a guy member 34 extending outwardly of the outer the corner 24 of the support 12 toward each other and insure that the outer frame 1-0 is firmly positioned for rotatable motion between the support 11 and the support 12.
In the specific embodiment of the invention disclosed 38 of the outer frame 10 and a pin 39 is positioned midway along the side 40 of the outer frame 10, and it is between these pins 37 and 39 that the inner frame 13 is positioned by extending the pin 37 into a sleeve 41 on the side 42 and the pin 39 into a sleeve 43 on the side 44 of the inner frame 13. The sleeve 41 is freely rotatable about the pin 37 and the sleeve 43 is freely rotatable about the sleeve 39. The axis of rotation of the sleeve 41 coincides with the axis of rotation of the sleeve 43 and, as a result, the inner frame 13 has an axis of rotation within the outer frame 10 extending between the sleeves 41 and 43. The sleeve 41 is located along the length of the side 42 of the inner frame 13 and the sleeve 43 is located along thelength of the side 44 of the inner frame 13 so that the weight on the inner frame 13 is substantially balanced about its axis of rotation.
-This arrangement of the outer frame 10 and the inner frame 13 results in the outer frame 10 being freely rotatable about an axis of rotation extending between supports 11 and 12 and the inner frame 13 being freely rotatable about an axis of rotation perpendicular to the axis of rotation of the outer frame 10. The weight of the inner frame 13 is not only substantially balanced about its own axis of rotation, but it is also substantially balanced with respect to the axis of rotation of the outer frame 10. As a result, neither the weight of the outer frame 10 nor the weight of the inner frame 13 tends to cause either the outer frame 10 or the inner frame 13 to rotate about its axis of rotation.
Two clamps 45 and 46 are slidably mounted on the side 42 of the inner frame 13, and two clamps 47 and 48 are slidably mounted on the side 44 of the inner frame 13. A lower bar 49 extends parallel to the axis of rotation of the inner frame 13 between the clamp 45 and the clamp 47, and an upper bar 50 extends parallel to the axis of rotation of the inner frame 13, between the clamp 46 and the clamp 48. The lower bar 49 and the clamps 45 and 47 are slidably movable with respect to the axis of rotation of the inner frame 13 and the upper bar 50 and the clamps 46 and 48 are slidably movable with respect to the axis of rotation of the inner frame 13. This permits the distance between the upper bar 50 and the lower bar 49 to be adjusted. The clamps 45, 46, 47 and 48 have bolts 51 extending through them which, when rotated, cause the clamps 45, 46, 47 and 48 to firmly grip the inner frame 13 and when the lower bar 49 and upper bar 50 have been positioned a desired distance apart, they are fixed in position by use of the bolts 51-to tighten the clamps 45, 46, 47 and 48 against the inner frame 13.
A foot bar 52 is fixedly attached to the lower bar 49 and a hand bar 53 is fixedly attached to the upper bar 50. The foot bar 52 lies in a plane substantially perpendicular to the sides 42 and 44 of the inner frame 13 and bisects and is bisected by the lower bar 49. Similarly, the hand bar 53 lies in a plane perpendicular to the sides 42 and 44 of the inner frame 13 and bisects and is bisected by the upper bar 50. At each extending end of the foot bar 52 are foot plates 54 and at each extending end of the hand bar 53 are hand grips 55. A person desiring to exercise using the exercising device positions himself in the exercising device by placing one foot on each of the foot plates 4 and by gripping one hand grip 55 in each of his hands.
A leg strap 56 is provided adjacenteach of the foot plates 54 and an arm strap 57 is provided adjacent each of the hand grips 55. With the leg straps 56, a person securely fastens his feet to the .foot plates 54 and with the arm straps 57 he securely fastens his hands to the 4 hand grips 55. A belt 58 of webbing, leather or similar material is positioned within the inner frame 13 by extending a strap 59 of elastic material between the side 42 of the inner frame 13 and the belt 58 and a strap 60 of elastic material between the side 44 of the inner frame 13 and the belt 58 and the person using the exercising device places this belt 58 around his waist. 7
Since the distance between lower bar 49 and the upper bar 50' is adjustable, persons of various heights may position themselves within the innerframe 13 of the exercising device between the lower bar 49 and the upper bar 50. Moreover, the size of the belt 58 is adjustable in the conventional manner and persons having various waist sizes are easily accommodated by the exercising device.
The adjustability of the positions of upper bar 50 and the lower bar 49 not only permits the exercising device to accommodate persons of various heights, but more significantly, it permits the center of gravity of a person positioned within the exercising device to be shifted with reference to the axis of rotation of. the outer frame 10 and the axis of rotation of the inner frame 13. If the lower bar 49 and the, upper bar 50 are placed within the inner frame 13 so that the persons center of gravity is substantially at that location in which the axis of rotation of the outer frame 10 and the axis of rotation of the inner frame 13 intersect, a slight shifting of weight or uneven muscular exertion by the .person will cause the person and the inner frame 13 to change position in space. These circumstances are shown in dashed outline in FIGURE 4 and, under these circumstances, the person using the exercising device must have maximum coordination of all muscles of his body in order to control his motion in the exercising device. On the other hand, if the lower bar 49 and upper bar 50 are placed so that the persons center of gravity is below that'location in which the axis of rotation of the outer frame 10 and the axis of rotation of the inner frame 13 intersect, as shown in solid outline in FIGURE 4, the displacement of the center of gravity of the person will tend to cause the exercising device to position itself with the outer frame '10 in a neutral and relatively stable horizontal plane and the inner frame 13 in a neutral and relatively stable vertical plane. These are the inner frame 13 and the outer. frame 10 positions in which the person is in his normal-vertical attitude, and the tendency of the outer frame 10 and the inner frame 13 to position themselves in these positions because of the displacement of the persons center. of gravity results in greater muscular effort or shifting of weight being required to impart motion to a person.
Thus, the adjustment of the upper bar 50 and the lower bar 49 not only permits the exercising device to accommodate @persons of various heights, but it also permits the sensitivity or responsiveness of the exercising device to be adjusted to the person using the exercising device. Where the individual has little skill, the exercising device is adjusted for maximum displacement of the persons center of gravity and minimum sensitivity. As.
the skill of the person increases and for skilled persons, the center of gravity of the person is brought closer to or to that location in. which the axis of rotation of the outer frame 10 and the axis of rotation of the inner frame.13 intersect and the exercising device has maximum sensitivity. 7
The elasticity of the straps 59 and 60 is selected by using known materials to permit limited freedom of motion of the waist and adjacent portions of the persons body as his position changes in the exercising device. Some lack'of rigid support for and motion of the waist is essential if the person is-to exercise all muscles of his body. Thus, the straps 59 and 60 must yield withthe persons weight as he rotates in the exercising device. However, the straps 59 and 60 must limit the motion of the persons waist to a limited degree in order to prevent undue strain upon the person because of a complete laclt of support for his waist. The proper elasticity-of the straps 59 and 60 for persons of various weights is most easily provided by a plurality of .both straps 59 and 60, each with a different degree of elasticity suitable to a particular range of weights.
Accordingly, the straps 59 and 60 are made to be interchangeable with the other straps 59 and 60 so that a set of straps 59 and 60 may be selected which is most suitable for the weight of the persondesiring to use the exercising device. In the specific embodiment of the exercising device described herein, the interchangeability is achieved by joining the straps 59 and 60 to the sides 42 and 44 with a hook 61 and eye 62 arrangement. Without this interchangeability, a set of straps which would properly support the waist of a slender person would be wholly inadequate to support the waist of a heavy person. Similarly, straps which would properly support the waist of a heavy person would provide too much support for a slender person. This interchangeability or adjustability of the straps 59 and 60 and the adjustability of the lower bar 49 and the upper bar 50 permit the exercising device to be used by persons of various heights, skills and weights.
It will be obvious to those skilled in the art that many variations may be made in the embodiment here chosen for the purpose of illustrating the present invention without departing from the scope thereof as defined by the appended claims.
