Jan. 3, 1961 c. A, WILTROUT TRACTION BELTS Filed 001:. 30, 1956 INVENTbR. Creed A. W/Hr'oaf A TTUR/VE Y This invention relates to an improvement in traction belts and deals particularly with an apparatus capable of holding a foot board at a predetermined distance from the waist of the wearer, and the method of applying the same.
During recent years the use of traction belts has become increasingly popular. These belts are generally sized for two inches and normally include a body-encircling portion with straps sewn down the sides and buckled to a foot board. A considerable difficulty is experienced in providing the necessary tension in the straps extending from the belt to the foot board. A pull upon these straps tends to cause the belt to slip downwardly on the body. Accordingly, unless the belt encircling the body is tightened to an uncomfortable degree slippage of the belt will occur.
Accordingly, it is an object of the present invention to avoid the previous difficulty found with these known types of traction belts and to size my improved belt for a great deal more than two inch fittings.
Another feature of the invention is to provide an improved traction belt designed to extend around the waist of the wearer and includes connecting straps extending from opposite sides of the belt to engage opposite ends of a cross member. This cross member normally extends beneath the feet of the patient and as the traction straps pull down the traction belt snugs up without pressure on thelower abdomen.
A feature of the present invention resides in the provision of a traction belt having a body encircling member and connecting straps extending from opposite sides of the belt to a foot engaging cross member. The connecting straps are at least partially doubled and ends of the strap extend through slip rings or other such means to extend in opposite directions about the body. When these straps are secured in body encircling position any pull upon the straps is transmitted around the waist to the opposite side of the body. Thus, if the upper portions of the straps lie outwardly of the body-encircling belt, any pull upon the straps tends to tighten the engagement of the belt about the body.
A feature of the present invention resides in the provision of a traction belt having a body-encircling belt portion which is split and which may be secured to encircle the waist of the patient. A pair of strap guiding rings or other suitable means are provided on each side of the belt. A doubled strap extends downwardly from each side of the belt, the ends of the straps extending through the strap guiding loops or rings. The ends of the straps then are guided in opposite directions about the body of the patient and include buckle means with which the straps may be secured in body-encircling position. A downward pull upon the center portions of the doubled straps is contracted through the straps to the opposite side of the body acting to draw the body-encircling belt more tightly about the body of the patient.
A further feature of the present invention resides in the n tz is e Few r provision of guides on the body of the belt through which the straps extend. These guides act to hold the ends of the straps to the belt so that the straps will be located in a desired location when the belt is being applied and removed.
A further feature of the present invention resides in the provision of a novel means of connecting the straps to the foot board. Usually the foot board is provided with attached buckles to which the straps may be attached. In the present construction the foot board is equipped with notches near its opposite ends, these notches being narrower at the point of entrance to the notches then at the base of each notch. The bases of the notch is wide enough to accommodate the fiat strap. Accordingly, the foot board may be easily attached in adjustable loops at the ends of the straps by bending or flexing the straps during insertion into the notches. When once in place in the notch, the narrow entrance portions of the slots prevent the disassembly of the straps from the notches.
These and other objects and novel features of my invention will be more fully and clearly set forth in the following specification and claims.
In the drawings forming a part of my specification:
Figure l is a front elevational view of a traction belt showing the arrangement of straps therein.
Figure 2 is a rear elevational view of the belt shown in Figure 1.
Figure 3 is a side elevational view of one side of the belt.
Figure 4 is a perspective view of the lower extremity of one of thebelt members.
Figure 5 is a perspective view of the foot board.
Figure 6 is a side elevational view of the lower extremity of one of the belts.
The belt is indicated in general by the letter A. The belt is designed to encircle the body above the hips and around the waist and includes ends 10 and 11 on opposite sides of the front center. These ends 10 and 11 are designed to overlap to some extent, the end 11 overlying a portion of the end 10 in normal arrangement. Straps 12 are anchored at 13 to the belt end 10 at a point opposite from the extremity thereof. These straps 12 are designed to support buckles 14 of any suitable metal.
Straps 15 are connected to the belt end 10 at a point materially opposite from the extremity thereof as indicated at 16. These straps 15 are designed to extend into the buckles 14 and to be held by these buckles to hold the body of the belt A in body-encircling position.
A pair of guide straps 17 extend from top to bottom of the belt at points opposite from the ends 10 and 11 of the belt A, these guide straps being located forwardly of the hips when the belt is in place. These guide straps 17 are secured to the body of the belt A along vertically spaced lines of connection, the upper two lines of connection 19 and 20 forming a loop between the guide strap 17 and the body of the belt for the accommodation of one traction strap and the lower two spaced lines of connection 21 and 22 forming a second loop for the accommodation of a portion of the other traction strap. Thus, the guide straps 17 form in effect flat guide loops for holding the two traction straps at the proper elevation.
A second pair of guide straps 23 extends from the top of the belt body toward the lower edge thereof, these straps being secured to the body of the belt at the upper ends 24, and at transverse lines of connection 25 at points spaced from the upper ends 24. These straps 23 are diagonally folded as indicated in Figure 3 to provide longitudinally extending center portions 26, and to support rectangular loops 27. The straps 23 are secured to the belt body along diagonal lines of stitching 28. The straps 23 are also diagonally folded at 29, and terminate in. upwardly extending portions anchored at their upper.
ends to the belt body at 3.0. Rectangular loops 33 are anchored at the diagonal folds by rows of stitching 32. The: upwardly extending portion of, each strap 23 is anchored to thebelt at a-point 31 spacedfrom the upper end of the strap to providea loop for the accommodation of oneof the traction belt straps which willbe later described.
The body of the belt is formed of two panels, 34 and 35 of strong fabric provided with a soft fleecy inner surface. A panel 36 of elastic fabric is provided between the: panels 34 and 35 to overlie the center of. the back. The elastic panel 36 is preferably slightly wider at its lower edge than at its upper edge to better fit the portion ofthe body encircled by the belt. The advantage of. this elastic panel 36 will be later described.
The upper and lower edges of the fabric panels 34 and 35 are bound. by suitable binding tape such as 37 and 39 to provide edges which are rounded and which will not cut into the flesh of the patient. The binding tapes37 and- 39 usuallyextend continuously from the ends of the panels connected to the elastic panel. 36 to the free. ends and 11 and extend continuously around these ends as is indicated in Figure 1 of the drawings.
The traction straps are shown in Figures 4 and 6 of the drawings to be centrally doubled intermediate the ends thereof, the doubled center portion 4t} supporting a connecting loop or ring 41. One belt is indicated in general by the numeral 42 while the other belt is indicated in general by the numeral 43. Both belts are similar in construction.
The belt 42 is folded at 40 to include the loop 41 and the. ends 44 and 45 of the belt extend upwardly'and through the guide loops on one side of the belt, the end 44 extending through the guide loop 27 and the other end 45 extending through the guide loop 33. The end 44 extends forwardly overlying the lower portion of the front of the belt, extending through a loop between the lines of connection 21. and 22 of one guide strap 17 and being of sufficient length to extend past the front center portion of the belt, terminating as indicated in Figure 1 at 46. The rear portion of this same belt extends through the guide ring 33 slightly to therear of the body and extends over the lower portion of the rear of the belt to extend diagonally upwardly across the back of the belt and beneath the guide strap 23 between the points of connection 30 and 31. This belt portion 45 then continues around the side of the body above the hip bones and through the loop formed by the lines of connection 24 and 25 of one guide strap 23, terminating in a belt buckle 47 located to the right of the center of the belt and near the upper edge thereof. The strap portion 45 also extends between one guide strap 17 and the body of the belt between the lines of connection 19 and 20.
A short strap of material49 is secured to the belt end 44 on opposite sides of the portion of this belt extending between the guide strap 17 and the body ofthe belt on the left side of the center. This strap 49 is anchored at its ends to the belt end 44 so as to encircle a portion of the strap 17 to prevent this end of the strap from being removed from beneath the guide strap. This, atrangement is provided to prevent the strap from being detached and improperly replaced.
The opposite traction belt 43 is similarly formed. One end 59 of the belt 43 extends forwardly through one guide loop 27 between the guide strap 17 and the body of the belt on the right side of the front of the belt, and extends diagonally across the front and upwardly to terminate in a free end 51. A short strap. member 52 is connected to the belt end and overlies the strap 17 to hold the strap end from withdrawal from beneath the guide strap 17. The opposite end 53 0f the strap 43 extends forwardly through a guide loop 33- and extends diagonally across the. backof the belt andbeneath. the
guide strap 23 on the left rear side of the belt between the lines of connection 30 and 31. The strap end 53 then encircles the upper portion of the left side of the belt, and extends beneath the guide straps 23 and 17 to terminate in a buckle 54 which is located near the upper edge of the belt on the left side of center. The belt end 53 extends between the lines of connection 24 and 250i the guide strap 23 and between the lines of connection 19 and 20 of the guide strap 17, the strap 53 is sewn to belt A (not shown) near buckle 54 to prevent slippage and the withdrawal of the strap.
The central portion vof the belt43 is supported by the rectangular loops, 27 and 33 on the right side of the traction belt to extend downwardly from the belt. The rectangular loops fold the belt neatly and flatly so as to insure the comfort of the patient, and supports a loop 41 similar to that shown in Figures 3 and 4 of the draw- The foot engaging boardis indicated in general by the numeral 55 and comprises a short length of finished board having smoothly rounded edges and of a, width sufficient to extend beyond the feet of the patient on opposite sides thereof. Spaced notches 56 are provided in one edge of the .boardgto accommodate strap loops which will bedescribed- Bases of the notches 56 are approximately equalin width to the width of the straps forming the loops but the inlet portions of these notches are usually narrower. As a result the straps must be bent during insertion and removal from the notches and the natural tendency of the strap to remain flat prevents them from being accidentally disengaged from the notch.
As is. indicated in Figures 4 and 6 of the drawings connecting straps such as 57 are provided to connect the loops 41, at the lower folded ends of the, traction straps to the foot board 55. The straps 57 are provided with short looped end 59 encircling the lower side of the loop 41 and an opposite end 60 which is looped over the center bar 61 of a belt clasp 62. The clasp 62 comprising a rectangular wire loop having a central crossmember 61 anchored to the belt end. The strap 57 extends through the clasp extending on one side of the rectangular loop end on the opposite side of the center bar 61. The loop is preferably roughened to prevent slippage of the belt relative thereto. The clasp 62 provides a means of shortening and lengthening the effective length of the straps 57. Obviously, by moving the clasp upwardly while the belt is slack the distance between the upper end59 and the lower folded end 63 of the belt 57 may be shortened. By binding the clasp 62 downwardly this distance may be increased. The folded lower end of the strap 57 is looped about a portion of the foot board 55, the strap engaging in an increasing notch 56.
The belt is applied in the manner which will be described. The belt is placed to encircle the waist of the patient with the ends 10 and 11 of the belt overlapping. The straps 15 are then inserted through the bucklesfl iand pulled tight so that the resilient panel 36 is slightly extended in length. The straps 57 are adjusted to approximately the proper length and the looped lower ends of these straps are placed to encircle the. foot board 55 and engaged in the notches 56.
The traction straps 4-2 and 43 are then drawn tight to provide the necessary pull upon the foot board. This is accomplished by engaging the end 46 of one strap in the buckle 47 at the opposite end of the same strap. The end 51 of the other traction belt is also engaged in the buckle 54 at the opposite end of this strap. As the belts are drawn tight, they apply pressure against a side of the body above the hips, the tension of the strap at the right'side of the belt applying pressure against the left side of the body and the pull upon the strap at the left side of the belt applying pressure to the right side of the body.
Any increase inforce upon the tractionstraps acts to tighten the beltupon the body and to. apply additional pressure above the hips. As a result of this arrangement, the normal tendency of the traction straps to pull the belt downwardly upon the body is eliminated.
The guide rings or loops are preferably located slightly to the front and slightly to the rear of the sides of the hips so as to provide equal tension on the front and the rear portions of the straps. As the free ends of the traction belts are held in place by the anchoring straps 49 and 52 and by the buckles 47 and 54 at the opposite ends of the straps, there is no tendency for the straps to become disengaged when detached, thus preventing improper reinsertion of the belt straps.
The elastic panel 36 forms an important part of the present invention. While elastic inserts have been previously used in belts of a difierent type, they have not been practical in traction belts, as the pull from the foot board acts to expand the belt and draw it downwardly on the hips. As a result, traction belts have usually been made in numerous sizes, as it is essential that the belt fit tightly and that the straps be secured to the belt at the sides thereof.
With the elastic panel 36, not only does the belt fit better and more comfortably, but by properly adjusting the belt strap 15, the elastic may be expanded to position the strap supporting loops at the proper location on the body. The belt tightening straps may be loose or tight to suit the individual need. As a result, the effective size of the belt may be varied over substantial limits, greatly reducing the number of stock sizes which must be available to fit various persons.
In accordance with the patent statutes, I have described the principles of construction and operation of my traction belt, and while I have endeavored to set forth the best embodiment thereof, I desire to have it understood that obvious changes may be made within the scope of the following claims without departing from the spirit of my invention.
