United States Patent TRACTION TREATMENT DEVICE Floyd M. Uhland, Long Beach, Calif. Application January 29, 1954, Serial No. 406,933 Claims. (Cl. 128 -75) variable and determinable amount of traction upon a patient without the necessity of maintaining a supply of weights.

The construction of this invention features means for adjusting the lever arm about which a single weight may be utilized to vary the tractive force applied on a patient.

Further, means are provided for adjusting the device in a simple and convenient manner to the height of the patient.

Still further objects and features of this invention reside in the provision of a traction treatment device that is strong and durable, simple in construction and manufacture, formed from a minimum number of parts, which can be readily transported from one location to another, or which may optionally be associated with a bed or like supporting structure, which includes means for supporting the weight when it is desired to adjust the device, yet which is inexpensive to manufacture, thereby enabling wide distribution to hospitals and like institutions.

These, together with the various ancillary objects and features of this invention which will become apparent as the following description proceeds, are attained by this traction treatment device, preferred embodiments of which have been illustrated in the accompanying drawings, by way of example only, wherein:

Figure l is a perspective view of a traction treatment device comprising the present invention;

Figure 2 is an enlarged sectional detail view illustrating the construction of the housing for the weight and the means for supporting the weight during adjustment of the device;

Figure 3 is an enlarged elevational View of the substantially L-shaped member and the associated slides forming important elements of the invention;

Figure 4 is an enlarged sectional view as taken along the plane of line 44 in Figure 3;

Figure 5 is an elevational view of a modified form of the invention adapted to be associated with a hospital bed, with parts thereof being broken away for greater detail;

Figure 6 is an enlarged front elevational view of the means for mounting the pulley on the supporting arm of the device; and

Figure 7 is a vertical sectional detail view as taken along the plane of line 7--7 in Figure 6.

With continuing reference to the accompanying drawings wherein like reference numerals designate similar parts throughout the various views, and with initial attention directed to the embodiment of the invention as is shown in Figures 1 through 4, it will be noted that there is provided a standard 10 which rises from a base 12 in the form of a stool having an enlarged horizontal support member 14 to which rollers or casters 16 are attached, the rollers 16 being especially adapted to be utilized in moving the traction treatment device from one location to another by merely tilting the device back onto the rollers and then pushing it along the floor or other supporting surface.

A preferably upwardly and outwardly extending supporting arm 18 preferably integral with the standard 10 is provided and has a slot 20 within which the pulley 22 is mounted. A pair of spaced

ear members

24 and 26 are secured to the standard 10 and extend upwardly and in the opposite direction from the arm 18. Pivotally mounted between the

ear members

24 and 26 is a substantially L-shaped member 28 having a substantially horizontal lever arm 30 and a vertical arm 32.

There is slidably adjustably secured on the horizontal lever arm 30 a slide 34 which is lockingly held in a selected position by means of a fastener 36. An eye member 38 is integrally formed with the slide 34 and one end of a cable 40 is attached to the eye member 38. The other end of the cable 40 has a weight 42 secured thereto. The Weight 42 is secured within a housing 44 of tubular shape which is welded or otherwise secured to the standard 10. A pulley 46 is suitably mounted on the standard 10, and the cable 40 is entrained about the pulley.

Means are provided for supporting the weight 42 when it is desired to adjust the traction treatment device. A slot 48 is formed in the housing 44 and by means of a bracket 50, a substantially L-shaped stop member 52 is pivotally mounted on the housing 44. The L-shaped member 52 hasone leg 54 of less length than the slot 48, While the leg 56 is longer than the slot 48. Hence, when it is desired to support the weight 42, it is merely necessary to pivot the stop member 52 inwardly so that the weight will engage the leg 54 whille the leg 56 will engage the housing 44. However, as soon as the weight 42 is raised somewhat, the leg 54 may be pivotally removed through the slot 48 and thence the Weight 42 can pass downwardly below the slot 48.

Slidably adjustably secured by means of a fastener 58 is a slide 60. The slide 60 is adapted to adjustably secure one end of a cable 62 to the vertical arm 32. The other end of the cable 62 is entrained about the pulley 22, and passes through the slot 20. The cable 62 has appended thereto a spring-type scale 64 having a hook 66 depending therefrom. Hence, when the hook 66 is attached to the portion of the patient requiring traction and the weight 42 released, the amount of traction will be directly readable on the scale 64. Further, upon adjustment of the slide 34 relative to the lever arm 30, the effective force applied on the patient can be adjusted.

Referring now to the embodiment of the invention shown in Figures 5 through 7, it will be noted that herein the standard 70 is of tubular configuration and has secured thereon a plate 72 to which an L-shaped member '74 similar to the L-shaped member 28 is pivotally attached. Mounted on the horizontal lever arm 76 of the L-shaped member 74 is a slide 78 having an eye member 80 to which one end of a cable 82 is attached. The cable is entrained about a pulley wheel 84 carried by the standard 70 and another pulley wheel 86 carried by the plate 72. A weight 88 received within the tubular standard 70 which thus forms a housing for the weight 88 is attached to the other end of the cable 82. A slot 90 is formed in the standard 70 and an L-shaped member 92 having one leg 94 of longer length than the slot 90 while the other leg 96 is shorter than the slot 90, is provided for selectively supporting the weight 88.

A supporting arm 98 is attached to the standard 70 and carried by the supporting arm 98 and adjustable relative thereto by means of a ball and socket joint 100 is a mounting plate 102 for a pulley wheel 104. The vertical arm 106 of the L-shaped member 74 has a slide 108 adjustably secured thereto which is provided for adjusting the cable 110 which is entrained about the pulley 104 and which has appended thereto a scale similar to the scale 64 and a hook similar to the hook 66.

The standard 70 is adapted to be secured to the head or foot stand of a bed by means of a clamp 112.

In use, the modified form of the invention is operated in substantially the same manner as the form of the invention shown in Figures 1 through 4. The position of the slide 78 determines the lever arm or the weight 88 and thus determines the amount of tractive force which will be applied upon the cable 110 and hence upon the patient.

From the foregoing, the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary. However, 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 shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claims.
