Title:
BODY SUSPENSION DEVICE
United States Patent 3593708
Abstract:
A device for suspending the portion of a human body above the pelvic region in an inverted position to provide a natural traction and to relieve the spinal column of gravitational compression which occurs when the body is in its normal upright position. The device includes a trapeze bar upon which is provided at least one rotatable platform having a padded face. When this face is initially disposed in a vertical position, the upper thighs of the legs may be pressed against it and if the upper part of the body is bent over the bar, the padded platform rotates on the bar to enable the person's body to be swung over the bar until the torso hangs downwardly, being supported by the thighs resting on the platform face. The legs of the body may be bent at the knees until the soles of the feet rest against vertical elements supporting the trapeze bar. Various other means are provided to facilitate the mounting and dismounting of the body for suspension and to render the latter more comfortable.

Description:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to therapeutic devices in general and in particular to those which are designed to enable the human body to relieve itself of certain mechanical stresses which it develops through walking, standing and sitting in an erect or somewhat erect position. However, since this invention involves the use of a trapeze bar like that employed in the field of acrobatics, it also relates to devices utilized in that field as well. With the present invention, however, the basic trapeze bar is adapted to support the body weight relatively comfortably in an inverted body position for limited periods of time to provide natural traction and to relieve spinal compression which naturally occurs when the body is in its normal upright position.
2. Description of the Prior Art
As far as the medical field is concerned, traction is usually accomplished by providing various types of mechanical devices such as cables, pulleys, weights and cycling machines designed to apply a pulling force.
So far as known by the present inventor, prior to the present invention doctors prescribing traction treatment for patients have not recommended a trapeze-bar-type device for such treatment.
Trapeze bars are, of course, quite ancient in their use in acrobatics. However, they do not lend themselves to comfortably suspending a person in an inverted position with all his weight supported on his thighs since the entire body weight would be distributed over a very small area of the thighs in contact with the bar. For this reason, such trapeze bars have not been utilized for therapeutic purposes in treating back disorders.
SUMMARY OF THE INVENTION
The present invention permits a trapeze bar to be employed for treating back disorders by permitting the human body to be suspended in an inverted position by the leg thighs and stabilized by disposing the legs upwardly with the feet resting upon the pair of vertical elements which support the bar. This is accomplished by providing at least one rotatable platform on the bar one face of which platform is padded. By the use of this platform, the body weight is distributed over a much greater area than it would be were it all supported by the thighs resting on the bar itself. The padding further affords additional comfort by itself yielding under the pressure of the user's thigh muscles. To prevent the person, when mounting the bar from a standing position and swinging over it to the inverted position, from overswinging and possibly falling off, a transverse element is extended between the vertical elements above from the bar at approximately the level where the person's ankles would pass in an arc about the bar if overswinging should occur. In addition, since most people who would use the present invention are not acrobats, pullup loops are preferably provided on or in proximity to the vertical elements just above the bar in order to permit the person, when dismounting, the swing himself back about the bar to the standing position on the floor. Without such straps, the average person might find himself forced to dismount by swinging completely over the bar and to land on the floor in a sitting position.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 illustrates the manner in which the preferred embodiment of the invention is set up and utilized. A cross-support bar 10 is secured between the sides of a door frame 12 and over this bar 10 are slipped two hooks 14, 14a, the lower extremities of which are formed as eyes 16 to receive a locking fixture 18 securing the upper bight or loop 20 of a cable 22. The cable 22 hangs downwardly about half the distance between the bar 10 and the floor 24, and with another similar cable 22a supported by the other hook 14a, serves to support a trapeze-type transverse bar 26 by a stud-nut combination 28. The bar is preferably knurled toward both ends at 30, 30a. The bar 10, before assembly, however, is passed through a pair of padded blocks 32, 32a, separated by a tubular collar 34. Each block 32, 32a as shown in FIGS. 5, 6 and 7, is preferably made of wood, and is bored through at 36.
One face of such block 32, 32a, however, is provided with a foam rubber pad 38, which is covered by a naugahyde or leather sheet 40. Each cable 22 may be covered by a rubber or plastic sheath 42. In addition, the bight or loop 16 of each cable 22, 22a may serve to receive a clip fixture 44 which supports a looped pullup strap 46. Optionally, there may be provided over the sheathed cable 22, as shown in FIGS. 9 and 10, a foot stirrup 50. Although it is preferred that each block 32 be substantially square, as shown in FIG. 6, an alternative form of the block could be rectangular, as is 52 in FIGS. 8, 14 and 15. Lastly, a crosspiece 54 may desirably be provided to extend between the upper portions of the cables 22.
In use, a person approaches the bar from a standing position until both thighs of his legs come in contact with the padded faces of the blocks 32, 32a. Although both blocks tend to rest with their padded faces 38 facing upwardly, the blocks 32, 32a are rotatable on the bar 26. Consequently, when a person's thighs are brought into contact with the blocks, the blocks may be rotated 90° to a vertical position, thereby to enable the person to be placed in contact with the padded faces 38 of the block. The person then grasps the knurled ends 30 and 30a of the bar 26 and swings his body over the bar until his feet strike either the sheathed cables 22, 22a or the crosspiece 54, whereupon the feet may be inserted in the stirrups 50 and the upper part of the body is then left to hang for a prescribed period, such as 2 or 3 minutes. This suspension of the body will be found greatly to relieve the compressional stress to which the back skeleton is normally subjected through gravity when the human body is in its erect position. The natural traction may be further increased by providing a weighted collar 56 as shown in FIG. 1A. In addition, if the back should require some heat treatment, a heating pad 58 may be strapped on prior to the person's mounting the bar. If the bar is mounted in sockets 60 which are secured to the doorjamb by heavy screws 62, there will be no danger of the person pulling the bar 10 from its support position. When the person has suspended himself the proper length of time, he then grasps the loops 48 of the pullup straps 46 and rotates his body about the bar in the opposite direction until his feet again touched the floor.
In the alternative embodiments of the invention, shown in FIGS. 11 through 19, a unit similar to that of the FIGS. 1 through 7 embodiment may be mounted without the use of the crossbar 10 directly into the upper transverse portion of the doorjamb 64 by heavy eye screws 66. In lieu of the foot stirrups 50, flat blocklike footrests 68 may be employed. In addition, in lieu of bored blocks, the blocks may be mounted on the bar 26a by means of brackets 70.
In the embodiment of FIGS. 17 through 18, a series of U-shaped receptacles 72 are screwed into the wall and serve to receive the bar 10, the purpose of these receptacles being to permit the bar to be raised or lowered depending upon whether the device is to be employed by a short or tall person. In addition, in this embodiment, in lieu of the supported cables 22, there is provided a fabric-type support assembly 74. This assembly may be fabricated of a material such as is employed for seat belts or cargo straps and may be put together with suitable end loops 76 and 78 to receive respectively the bars 10 and 26a. The latter bar may further be provided with bicycle-type handles 80 in lieu of the knurling 30, 30a of the bar 26 of FIGS. 1 through 7 embodiment. In addition, the crosspiece 54a may be stitched directly to the vertical support 82 as may also pullups 84.
It will be noted that in each of the several embodiments thus far described, thigh support has been provided by pairs of rotatable blocks. While these are to be preferred particularly to support a male, support could be provided by a single wide wooden platform as illustrated in FIG. 20.
