HIS ATTORNEY United States Patent 3,388,700 MEANS AND PROCESS FOR EFFECTENG PERIODI() BGDY INVERSHON Forrest Kindle Mountz, 22609 Garfield, St. Clair Shores, Mich. 43082 Filed Aug. 27, 1964, Ser. No. 392,659 15 Claims. (Cl. 12S-24) ABSTRACT 0F THE DISCLOSURE Means and process for effecting inversion of ones own body having a pivotally supported table and rail means at the head end of the table by which one can lie upon the table and walk the head end of the table downwardly by grasping the rail means.

This invention relates to means and -process for effecting periodic body inversion.

Its object is to provide means and process whereby a person can reverse the gravitational effects upon his body and its anatomical parts and systems periodically at his pleasure for relaxation and stimulation of circulation, for relief from tensions and for other healthful benefits.

The foregoing object and other advantages of the present invention will become apparent during the course of the following description taken in conjunction with the accompanying drawings in which:

FIG. 1 is a side elevational view of a body suspension inverting bed device embodying the present invention;

FIG. 2 is a like view of said device with its table in an inverted position;

FIG. 3 is a plan view of said device;

FIGS. 4A and 4B are perspective views of parts of said device showing, respectively, the lock for its table and the underside of the latter;

FIG. 5 is an end elevational view of said device;

FIG. 6 is a perspective view of a part of said device showing the axially moveable footboard; and

FIGS. 7-9 are side, front and rear elevational views of the suspension mechanism of said device.

Referring to the drawings in greater detail, 10 indicates the base of the device which, in the instance, has four legs and rotatably supports a padded table 12 via an axle 15 and hub 16 which are aflixed, respectively, to the table 12 and base 10. A user lies on the table 12 and while he 4is getting off and on it is locked in its horizontal position by means of a detent 17 which is carried in a flange 18 affixed to the table 12. The detent 17 projects into a blind aperture 20 in the hub 16 which prevents rotation of the table. A ring 22 is within reach of the user while in a supine position who can pull upon it after he is settled on the table and ready to release it for rotation. The ring 22 is joined to the detent 17 by a wire 23 and when the ring is pulled upon it compresses a spring 24 which serves to p'reload the detent 17 and insures entry of the latter into the aperture 20 which the table assumes the horizontal position.

A footboard 30 is arranged at an end of the table so as to be moveable axially thereof over the pad thereon to accommodate the different weights and heights of various users of the device. The footboard is held fast in its movement toward the head of the table in any of its axially adjustable positions by a toothed rack 31 mounted on each side of the table and brake 32 which has teeth meshing with those on the rack. The brake 32 is supported for limited rotation between sideboards 33 joined to the footboard 30. The engaging end of the brake 32 is constructed in relation to the rack 31 so that it can rotate in one direction (anti-clockwise in FIG. 1) to release the footboard 30 for adjustment axially of the table.


Such end is elongated so that it is prevented from being rotated in the opposite direction (clockwise in FIG. 1) to hold the footboard against any amount of weight of a user tending to moving it toward the head of the table. A com-pression spring 38 operates against the footboard 30 and upon the free end of the brake 32 to keep its engaged end in mesh with the rack 31 in any of the adjusted positions of the footboard 30. To counterweight the head end of the table exactly in accordance with the particular height and weight of the user a counterweight is provided at the foot end of the table in the form of a bar 3S and slotted weights 36 removable from the bar.

The footboard 30 carries a body suspension mechanism which, in the instance, is in the form of a pair of ankle gripping means which individually grip the ankles of the user and support him in an inverted position without discomfort. Each such means comprises a webbing member 40 which has its two ends crossed and affixed spaced apart to the footboard 30 after one end is threaded through a slot in the other to forni a loop which grips the ankle of the user while his foot extends 4through the space between the crossover point of the webbing and the footboard 30 as best shown in FIGS. 7 9. The ankle gripping means exerts a progessively tighter grip on the user in proportion to his weight which increases his secur-ity but without discomfort in view of the wide band of webbing which wraps all around the ankle. As further security of the user a chest strap 42 may be provided by which he may strap himself to the table near its head end.

A pair of arcuate rails 45 are provided near the end of the table which are braced and joined to the base 10 so that they extend forwardly and upwardly to be within reach of the hands of the user when his arms are over his head while he is in a supine position by which r-ails he can walk himself into an inverted position. Whenever he lets go of the rails the user automatically returns to a horizontal position due to the counterbalancing effect of the axially moveable footboard 30. The force with which he returns is directly proportional to the force the user must use to walk himself down the rails so that in practice one would adjust the position of the footboard to require a minimum walking force. The extreme inverted position of the -table 12 is governed by the position of a stop 48 screw threaded Iinto a cross member 49 of the base 10 which in the case of the average user in positioned so that the table will rotate to one or two degrees under degrees, i.e. so that it always returns to the horizontal whenever the user lets go of the rails 4S. In the case of an experienced user who wishes -to remain in the inverted position and and relax with his hands free the stop 48 may be threaded further into the member 49 so that the table 12 goes one or two degrees beyond 90 degrees. An experienced user will wish to take advantage of the free use of his hands and massage parts of his body such as his face Where the effects of aging show most. For example, he may wish to massage under his eyes where bags tend to form from the effect of continuous gravitational pull upon his body. The beneficial effects from periodic body inversion upon the human body are thought to be due to the flushing of the upper half of the body with blood by the pull of gravity which draws the blood into cell and capillaries which otherwise would receive only small quantities of blood.

In use of the device the axial position of the footboard 30 which is best for a given user is determined by trying the table with the footboard in different positions until the table with the user on it is best counterbalanced. This position is marked and the footboard returned to this position lif it is moved for another user. The user makes sure that the detent 17 is in the aperture 20, i.e., that the table 12 is locked in its horizontal position by testing it as by pressing upon the head end of the ta-ble. With the table locked the user climbs upon it and places his ankles within the ankle gripping means on the footboard 39, i.e., each ankle is threaded through the loop of the member 40 and the users foot is placed between the crossed ends thereof. The user then buckles the chest straps 42 and grips the rails with his hands outstretched over his head and walks himself down the rails until he has reached such inverted position as he desires. As

previously mentioned the maximum inverted position he can reach is determined by the stop 48. When the user lets go of the rails 45 he will return to the horizontal position or he will remain in an inverted position in accordance with the threaded position of the stop 48 in the member 49. The user is either fully supported in a supine position or entirely suspended in a vertical position and partly both supported and suspended between these positions.

It will thus be seen that there has been provided by the present invention means and process for effecting periodic body inversion by which relaxing and healthful effects can be ybestowed upon the human body particularly from reversing the gravitational effects upon the bodys various anatomical parts and systems. While a preferred embodiment of the invention has been shown and described it is to be understood that modifications, variations and changes may -be resorted to without departing from the ambit of the invention as defined by the appended claims.
