THERAPEUTIC TRACTION APPARATUS
Abstract
A therapeutic apparatus for applying suspension traction to a
person to alleviate certain types of backaches. The apparatus
includes an annular support member supporting an inflatable
rubber-like tube. When the tube is in deflated condition the body
of the person may be passed through the opening of the annular
member. After the tube encompasses the body of the person below the
armpits, the tube is inflated to engage the body in snug
circumferential relation and, in such condition, the tube
cooperates to support the person so that the lower portion of his
body is suspended. An air compressor and controls within easy reach
of the person are provided for effecting inflation or deflation of
the tube.

Description
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
patient's 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 U.S. 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 person's body, the
apparatus being self-adjustable within a predetermined range 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 this invention is the provision of an
apparatus which requires no strapping of the body into a belt or
body encircling jacket and which requires no preliminary manual
adjustments prior to use, other than adjustments for the user's
height.
These and other objects and advantages of the present invention are
achieved by 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. The rate and degree of
inflation of the tube and deflation thereof are at the finger tip
control of the user for maximum comfort and convenience to the
user.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIGS. 1 through 4, the illustrated embodiment
comprises a supporting frame, indicated generally by the numeral
10, said frame including a platform base 11 having a central well
12. Three spaced metal tubular columns 13 are suitably secured in
upstanding relation to the base 11. A tubular section 14 is
telescopically received in each of the columns 13. Both the columns
13 and tubular sections 14 are provided with transverse openings 16
which may be moved into selective registration so that a pin or
bolt 17 may be passed therethrough to effectively secure the
sections 14 in adjusted vertical positions. The upper end of each
of the sections 14 terminates in a fitting 18 providing an open
socket to receive the body engaging sub-assembly indicated
generally by 19 and hereinafter to be described. The sub-assembly
19 comprises a generally annular sheet metal member 21, arcuate in
cross-section, and open inwardly of the circle, as illustrated in
FIG. 4. A plurality of headed pins 22, one for each of the fittings
18, is welded to the member 21 and extends outwardly thereof. As
seen in FIG. 3 two of the pins 22 are coaxially disposed for a
purpose, as will be hereinafter explained. As will be apparent by
reference to FIG. 1, the member 21 is supported in horizontal
position on the sections 14. A cushioning pad 23 formed of any
suitable foamed plastic or rubber overlies the top and outer side
surface of the member 21, in the manner illustrated in FIG. 4.
Received within the member 21 is an inflatable tube 24 of rubber or
suitable elastomeric material, the tube 24 being confined within
the member 21, except in the area facing the inner circle. Thus, as
will be hereinafter explained, when the tube 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. The member 21 is provided with a
suitable aperture through which is passed the valve stem 26 of the
tube 24.
A control switch 27 is mounted on one of the sections 14 within
convenient reach of the user. Said control switch is in electrical
connection with a motor driven air pump 28, the output end of the
pump being connected to the valve stem 26. The control switch 27
effects operation of the pump 28 to inflate the tube 24 and to
maintain it inflated to a desirable pressure condition, or to
deflate the tube, as desired.
A bar rest 31 is supported on a standard 32 attached to the base
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 are first
adjusted vertically in relation to the columns 13 so that the top
of the sub-assembly 19 will be substantially in alignment with the
armpits of the user when he stands on the platform base 11. The
tube 24 is first caused to be deflated so as to afford a maximum
opening within the sub-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 18 and, of course, may be rocked upwardly about the axis
of the two co-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 the control switch 27 to
effect operation of the pump 28 and thereby to cause the tube 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 the well 12 and out of contact with
a floor surface so that his body is supported entirely by
engagement with the sub-assembly 19 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 the support 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 the control switch 27 to
effect deflation of the tube 24 so that he may withdraw his body
from within the sub-assembly 19.
In the modified embodiment illustrated in FIGS. 5 through 8, the
body engaging assembly indicated generally by the numeral 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 a control switch 27' to an air pump 28' which
functions similarly to the corresponding parts hereinabove
described.
The member 21' is provided with a pair of generally L-shaped
brackets 34 suitably welded thereto. Each of the brackets 34
cooperates with a similarly shaped bracket 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 a bolt 37 and cooperating nut. The bracket 36 is
provided with a pair of headed studs 38 which are adapted to be
received in cooperating key slots 39 of wall 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 the wall 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 the body
engaging member 19' to his person. The wall standards 41, or
course, permit height adjustment of the apparatus.
It will be understood that in each of the embodiments each control
switch 27 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.
