Abstract
A traction device that is divided into two sections with one section moving relative to the other so that when the human body reclines thereon said portion of the body lying on the movable section is pulled relative to that portion of the body laying on the relatively fixed section. The surface of the two sections is resilient so that the body sinks therein producing a frictional holding or purchase on sections of the body to facilitate the exertion of the tractive force thereon.

PATENTE U JAN 1 2 I971 SHEET 2 UF 2 R. w .o m V M r d m. H V y 7 M m m mm Q E V v i In w QE 1 TRACTION Device] The present invention relates to a'supporting surface for a 7 tion is then moved relatively away from the fixed section,
thereby producing a tractive force in the human body between the portions of thebodysupported on'the two sections of the supporting surface. The relative .emovement of the two sections may be controlled by the patient lying onthe supporting surface by an incremental ratchet-typedri ve to advance the I movable section to produce the degree of traction required.
I-Ieretofore, portions of the body into which the tractive force was to be transmitted had to be attached, such as by harnesses' or belts, to'one surface and then weights or tractive members attached to another portion of the body to, in effect, pull the body.as in the old torture device, the rack. With the instant device, there is no need to secure the body to fixed surfaces and movable surfaces. The pulling or purchase is produced by the depression of the body into the resilient surfaces. The unique ratchetlike mechanism moves the members relative to one another 'so that the patient can actuate the mechanism, thereby being able to utilize the device without the help of a second person.
lt'is therefore an object of the present invention to provide a simple but unique traction-applying device.
It is a further object of thisinventionto provide a traction device that does not require the 'patient to be strapped thereon.
It is a still further object of this invention to provide a traction device that can be utilized by the patient, and thereby not require the aid of a second person-1 v These together with other objects andadvantages which will become subsequently apparent reside in "the details of construction and operation as more fully hereinafter described and claimed, reference being had to: the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

165A deep foam pad 18 generally conforms to and is fixed to the hinged panel 12,-with the panel 12 and foam pad l8forr'ning the relatively fixed section of the traction device. A pair of plates 20 and 22 are fixed to the endo'f panel 14 remote from V the hinge 16 in upstanding relationship'thereto with a roller 24 journaled on the plates 20 and 22 for'rotation therebetween.
The "end of the roller 24 journaled in .plate 22 extends therethrough and has a ratchet wheel-'26 secured for rotation therewith by means of the bolt 28. Aratchet movement device is mountedon plate 22 to provide the rotational force for the roller 24. The ratchet device has a lever 30'pivoted to plate 22 at its upper end thereof by pivot pin 32A ratchet member 34 is pivoted to the lever 30 generally at its midpoint by the'pivot pin 36 which is fixed to the ratchet 34 and joumaled for rotation in lever 30. The ratchet lever 34 extends beyond and overlies the ratchet wheel 26 so that the hook hook-shaped end 38 thereof can engage the teeth of the ratchet wheel. A spiral torsion spring 40 is mounted at one end in a hole in. a. pin 42 which is fixed on the plate 22. The other end of the spiral torsion spring extends through a hole in the pivot pin 36, which since it is fixed to the bracket member, imparts a counterclockwise rotation to the ratchet member 34 thereby maintaining the end 38 thereof in constant engagement withthe ratchet wheel 26. A link 44 is fixed to theend of lever 30 remote from pivot 'point 32 by means of a rivet 46,. Thus, the link 44 and lever 30 pivot as a unit-about point 32, with the ratchet member 34 pivoted on lever 30 so as to be in constant engagement with the ratchet wheel 26 at the counterclockwise urging of the spiral torsion spring 40.-'A coil tension spring .48 is mounted at one end to a pin 50, which is secured to the plate 22 at the lower edge thereof remote fromthe hinge point of the panels 12 and 14, and the other end of the spring 48 is looped through a hole 52 in the'end, of the link 44. The spring 48 thus biases the ratchet mechanism into its at rest or initial position, thereby providing for the urging of the ratchet to drive the ratchet wheel.
To prevent unwanted counterclockwise rotation of the ratchet wheel, an elongated lever 54 is pivoted about apin56 fixed to the plate 22 at the upper comer thereof. A pawl 58 is attached generally to the midpoint of the lever 54, at the pivot point 56 thereof, to extend downwardlyand engage the teeth of the ratchet wheel 26 with the end 60 thereof. A generally U-shaped spring 62 has one end extending through hole in pin 56 and the other end looped around the handle of lever 54. This imparts a generally counterclockwise motion to the lever and pawl 54 and 58 respectively, thereby urging the end 60 into constant engagement with the teeth of the ratchet wheel 26. When it is desired to freely rotate the roller 24, and attached ratchet wheel 26,, in a counterclockwise direction the pawl 58 can be disengaged therefrom by lifting on'the handle end of the lever 54.
To provide for remote operation of the ratchet mechanism by the patientutilizing thetraction device, a cable 64 isat tached tothe hole52 ,in the endof link $44 by any suitable means such asby the clamp 66 shown inthe drawings. Atube 68 extends from a point adjacentthe end of plate 22 to the other end of panel 14 adjacent the hinge thereofand is fixed to thepanel by means of tube clamps 70; The cable thus extends from the link 44 through the tube to a pointbeyond the hinge point 16 of the panel with a convenient pull device '72 mounted thereonfor the patient to graspand exert the ,pull thereon necessary to drive the ratchet mechanism.
An elongated carrier sheet of flexible material 74,,such, as canvas or vinyl, extends along the upper surfaceof the hinged panel 14 and is attached and rolled onto the roller 2A. The' free end of the sheet 74 is located adjacentthe hinge 16,,wherea loop 76 is sewed thereon. A rod 1: extends ttanSYersely through. the loop 76 and is substantially the width. of the hinged panels 12 and 14.;A pair of tension coil springs80 have one end thereof looped over each end of rod 78, extending beyond the loop 76, and the other ends thereoflfixed to the hinged panel 12 by any convenient means,'such as byascrew 82 as shown in the drawings. The spring'80ateach end of; the rod 78 tends to pull the flexible sheet 74 off-the roller, or keep it taut or in a state of tension between its ends.
To facilitate the storage of the device when not in use, or the transporting of the device with the patient who desires to use it, the hinge point 16 allows the panels 12 and 14 to be pivoted into a parallel relationship abutting one another, as shown in H6. 7. Thus, the deviceis not only simple to use and able to be used by a single person, but is convenient to transport or store.
The traction device also lends itself to the application of tractive force to a single limb, e.g. a smooth sheet can be inserted under one leg of a user thereby defeating the gripping power of the pad which will thereby apply the tractive force to the leg resting on the pad. Similarly, if a twisting tractive force is required, such as in the hips, one hip can be raised on a pillow and the tractive force will then be applied in a twisting manner. Also, with the basic design of the device showing one relatively movable pad, it can be seen that a plurality of movable pads can be applied to the basic structure to provide for specialized applications or where different tractive forces are required in different directions.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
