9 Claims, 8 Drawing Figures 1,119,904 7/1968 Great Britain ..128/75 1,371,332 12/1964 France ..128/75 THERAPEUTIC TRACTION APPARATUS BACKGROUND OF THE INVENTION This invention relates to a therapeutic traction apparatus for use in applying spinal traction to a person's body to alleviate certain types of backaches, although it is also applicable to various other therapeutic purposes.

Apparatus heretofore employed for applying spinal traction to a patients body involved the use of body encircling jackets or belts secured by straps around the person's body. and suspended as by ropes or cables from an overhead support. A more recent development is exemplified in a traction apparatus illustrated in US. Pat. No. 3,353,532. This apparatus requires rather complex manual fit-and-try adjustments in order to accommodate the apparatus to each user.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an improved apparatus for applying spinal traction to a persons body, the apparatus being self-adjustable within a predeterminedrange to different body sizes.

Another object of this invention is a, provision of an.

apparatus which in use affords a high degree of comfort to the user.

Still another object of thisinvention is the provision of an apparatus which requires no strapping ofthe body into a belt or body encircling jacket and which requires no preliminary manual adjustments prior to use, other than adjustments for the users height.

These and other objects and advantages of the present invention are achievedby an apparatus employing a body encircling elastomeric inflatable tube arranged to be inflated to closely hug the upper body portion of a person, below the armpits. Therate and degree of inflation of the tube and deflation thereof are atthe finger tip control ofthe user for maximum com.- fort and convenience to the user.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS 1 through 4,.the illustrated em-v bodiment comprises a supporting frame, indicated generally by thenumeral 10, saidframe including a.

platform base 11 having acentral well 12. Three spaced metaltubular columns 13 are suitably'secured in upstanding relation to the base 11. Atubular section 14 is telescopically received ineach of thecolumns 13. Both thecolumns 13 andtubular sections 14 are provided with transverse openings 16 which may be moved into selective registration so that a pin orbolt 17 may be passed therethrough to effectively secure the sections 14in adjusted vertical positions. The upper end of each of thesections 14 terminates in afitting 18 providing an open socket to receive the body engaging sub-assembly indicated generally by 19 and hereinafter to be described. Thesub-assembly 19 comprises a generally annularsheet metal member 21, arcuate in cross-section, and open inwardly of the circle, as illustrated in FIG. 4. A plurality ofheaded pins 22, one for each of thefittings 18, is welded to themember 21 and extends outwardly thereof. As seen in FIG. 3 two of thepins 22 are coaxially disposed for a purpose, as will be hereinafter explained. As will be apparent by reference to FIG. 1, themember 21 is supported in horizontal position on thesections 14. Acushioning pad 23 formed of any suitable foamed plastic or rubber overlies the topand outer side surface of themember 21, in the manner illustrated in FIG. 4.

Received within themember 21 is aninflatable tube 24 of rubber or suitable elastomeric material, thetube 24 being confined within themember 21, except in the area facing the inner circle. Thus, as will be hereinafter explained, when thetube 24 is inflated, it will expand from the deflated condition, illustrated by the broken lines in FIG. 4, to the inflated condition, illustrated by the solid lines in said figure. Themember 21 is providedwith a suitable aperture through which is passed thevalve stem 26 of thetube 24.

A control switch 27is mounted on one of the sections l4within convenient reach of the user. Said control switch is in electrical connection with amotor drivenair pump 28, the output end of the pump being connected to thevalve stem 26. The control switch 27 effects operation of thepump 28 to inflate thetube 24 and to maintain it inflated to a desirable pressure condition, or to deflate the tube, as desired.

A-barrest 31 is supported on a standard 32 attached to thebase 11. The bar rest affords means for supporting the body of the user in the manner illustrated in FIG-2, if the same is desired.

In the use of the aforedescribed apparatus, sections 14 I are first adjusted vertically in relation to thecolumns 13 so that the top of thesub-assembly 19 will 'be substantially in alignment with the armpits of the user when he'stands on the platform base 11. Thetube 24 is first caused to be deflated so as to afford a maximum opening within thesub-assembly 19 to receive the arms and shoulders of the user as he moves the upper part of his body through the opening. The sub-assembly is loosely supported in the fittings l8 and, of course, may be rocked upwardly about the axis of the twoco-axial pins 22 or moved as desired to facilitate positioning of the same on the body of the user. After the body has been thus encircled, the user actuates thecontrol switch 27 to effect operation of thepump 28 and thereby to cause thetube 24 to be inflated to a point where the body is snugly engaged circumferentially, in the manner illustrated in FIG. 2. The user may: then step off the surface of the platform base 11,

permitting his feet to be received within thewell 12 and I out of contact with a floor surface so that his body is supported entirely by engagement with the sub-assembly l9 and depends therefrom. Thus, the lower portion of the spine is free of engagement with any portion of the apparatus so that desired spinal traction is effected.

In another manner of use the user may swing his legs to position his knees over thesupport bar 31 and assume the position illustrated by the broken lines in FIG. 2. The treatment in either manner of use may be extended as long as desired and traction suspension may be terminated by the user merely stepping back upon the platform base 11 and then operating thecontrol switch 27 to effect deflation of thetube 24 so that he may withdraw his body from within thesub-assembly 19.

In the modified embodiment illustrated in FIGS. through 8, the body engaging assembly indicated generally by thenumeral 19 includes a sheet metal number 21', a cushion padding 23' and an inflatable tube 24', said parts being substantially similar to the corresponding parts in the first described embodiment. The tube 24' is connected through acontrol switch 27 to an air pump 28' which functions similarly to the corresponding parts hereinabove described.

Themember 21 is provided with a pair of generally L-shapedbrackets 34 suitably.welded thereto. Each of thebrackets 34 cooperates with a similarly shapedbracket 36. The

brackets

34 and 36 are provided with elongated slots to render them adjustable relative to each other and are adapted to be secured in an adjusted position by abolt 37 and cooperating nut. Thebracket 36 is provided with a pair of .headed studs 38 which are adapted to be received in cooperatingkey slots 39 ofwall standards 41 arranged to be mounted vertically on opposite sides of a doorway, as illustrated in FIG. 5, the

brackets

34 and 36 being adjustably extensible so as to be accommodated in doorways of different widths.

The modified embodiment hereinabove described permits use of the apparatus in places where storage space is limited and the arrangement is such that thewall standards 41 may be permanently attached to the door frame with the body engaging assembly 19' being readily removable from the doorway when not in use.

As indicated in FIG. 5, the user may avail himself of the use of a stool as a platform on which to stand when adjusting thebody engaging member 19 to his person. Thewall standards 41, or course, permit height-adjustment of the apparatus.

It will be understood that in each ofthe embodiments each control switch 21 or 27' is provided with a quick release arrangement, conventional in the art, to permit substantially instantaneous deflation of the tube, in the event the same becomes necessary by the user.

It will also be understood that while the drawings show body engaging assemblies which are annular in plan, my invention contemplates the use of assemblies which may be oval or of any other suitable form. Preferably, the body engaging assemblies may be fabricated in a plurality of sizes, each to cover a limited range of body sizes.
