Description
Field of the Invention
The present invention relates to lifting belts, and more particularly the type used by do-it-yourselfers and industry employees who from-time-to-time are required to lift loads which could cause back injuries.
Background of the Invention
The present invention is related to the field of lifting belts. Many sizes and varieties of lifting belts have been proposed and made and patented. Exemplary of such patented belts are U.S. Pat. Nos. 5,147,261; 4,907,576; and 4,964,401. While these lifting belts may serve the purpose of reducing back injuries, all of them are specially sized, which requires the marketer and manufacturer to make a minimum of four sizes: small, medium, large, and extra large.
Summary of the Invention
The present invention is directed to unisize type lifting belt containing basically three elements: the underlying wrap assembly with expandable back panel and overlapping closure ends; suspenders with four adjustable ends to secure to the underlying wrap assembly at varying positions in front and at two positions varying vertically in the rear; and expandable side pull portions which have a pair of elastic band portions and removably secured end tabs. The expandable side pulls are normally applied by snugly securing the side pulls to the underlying wrap assembly prior to lifting.
The principal object of the present invention is to provide a load belt which can readily adapt from a slender person to a large person from one particular size belt. Such persons may vary substantially in both girth and height as well as weight.
Yet another advantage of the present lifting belt is a structure which is inherently inexpensive to manufacture and cost efficient as well as cost effective for the end use.
A further advantage of the present invention is to provide a method for securing a properly adapted lifting belt to bodies of significantly varying size.

Description of Preferred Embodiments
The preferred embodiments of the present lifting belt are illustrated in their usage in FIG. 1. There it will be seen that the lifting belt assembly 10 is wrapped around a rather large man and the front two overlapping wrap end members secure the belt in place. Next to the large man is a small woman wearing the belt assembly 10 in which significantly greater overlaps appear in front, and the suspender adjustments are notably shortened. In this context the dimensions of the subject lifting belt assembly 10 become significant since they are developed to show proportion which make possible the wide adjustment which can be achieved.
The lifting belt 10 as shown in FIG. 2 includes the underlying non-expandable wrap assembly 11 and the expandable lumbar panel 12, and in the outer portion, the expandable side pull members 14. All of the elements of the belt are fastened together by a material known by the trademark Velcro. The Velcro has hook sides and a soft or locking side. In connection with the preferred embodiments, the hooks are shown in a curled configuration, and the locking portion in a softer wool-like configuration. In all instances, it should be remembered that the members may be reversed or, in the event releasable locking members of like configuration are employed, they are contemplated as well for the securement function.
In FIG. 3 it will be seen that the suspender assembly 16 has been adjusted differently than shown in FIG. 2. The showing in FIG. 2 is comparable to the adjustment of the lifting belt 10 for the large man shown in FIG. 1. Conversely, the showing in FIG. 3 shows a significant overlap of the wrap assembly 11 and the expandable side pulls 14 much as appears on the woman in the right-hand portion of FIG. 1. In both applications as illustrated in FIGS. 2 and 3, the last securing step is to position the removably securable end portions 15 of the expandable side pulls 14 over the releasably securable exterior portion of the wrap assembly 11. Thus as shown in FIG. 2, the wrap assembly 11 barely overlaps where it is employed on a person with a large waist, whereas the wrap assembly 11 and elastic side pulls 14 have a very substantial overlap to accommodate a slender person.
In FIG. 4 the suspender assembly and its securement to the wrap assembly 11 is more fully illustrated. Notably, each of the four suspender straps 26 have suspender securable ends 18 at their bottom portion, which ends 18 are secured by means of the end connectors 29. Buckles 28 are provided at the forward portion of the straps 26 in order to adjust for the space between the shoulder and the waist of the person wearing the belt.
Turning now to FIG. 5 it will be seen that the expandable lumbar panel 12 at the rear portion of the wrap assembly 11 includes stays 19 which are inserted in stay pockets 19'. As shown, four such stays are employed. The central two stays have a pair of suspender anchors 25 to which the lower portion of the suspenders are anchored. In this regard, it will be seen that the suspenders can extend well beneath the length of the lumbar panel anchors 25, and this in combination with shortening the suspender length through the buckles 28, achieve an adjustment of the entire suspender assembly 16 to accommodate the slender and smaller user.
The showing in FIG. 6 is the rear portion of the belt to where it will be seen that the expandable side pulls 14 are anchored to the center two back stays 19, and extend laterally to a position close to the wrap ends 21 of the wrap non-expandable wrap body portion 20. The locking wrap end 21 engages the front portion of the wrap ends 21 on the wrap surface 22 which, as will be noted, receives the locking members of the wrap ends 21, and the locking ends of the removable securing end portion 15. FIG. 7 shows the expandable side pulls 14 in their free or unsecured relationship to the wrap 20, and reveals that the preferred expandable side pulls 14 actually are a double overlapping elastomeric material with two sections 14, 14' as shown. The two sections are spread where they join the back stays 19 on the expandable lumbar panel 12, but taper to the single removable securing side pull end portion 15.
The suspenders are shown in plan view both front and rear in FIGS. 8 and 9. There, as stated before, each of the strap ends has a suspender securing end 18 which is readily secured to the wrap assembly 11 by means of the securement of the ends 18. The securing ends 18 are coupled by means of the loop end connector 29 to the balance of the suspender straps 26. The adjustment to the distance between the shoulder and the waist is made by the buckles 28 which are traditional adjustments for suspenders and will be readily understood by any user.
Applying the belt assembly to a user is illustrated sequentially in FIGS. 10-13. Initially the suspender straps 26 are passed over the shoulders, and then the wrap assembly 11 is secured around the waist. At this point the expandable side pulls 14 are left positioned to the wrap assembly in a non-expanded state, but in a ready position for securement when the wearer prepares to lift a load. FIG. 11 illustrates how the suspender assembly 16 is adjusted by both the adjustable buckles, and the positioning of the suspender securing ends 18 on the wrap assembly 11. Thereafter, as shown in FIG. 12, with the suspenders secured in place, the wrap assembly 11 is secured by attaching the wrap end 21 to the outer face of the adjacent wrap end.
Finally, as a load lifting is anticipated, the last step is shown in FIG. 13 where the expandable side pulls 14 are stretched in place and lockingly secured to the wrap assembly 11 which is beneath the side pulls. Here it will be further seen that the suspender anchors or securable ends 18 are beneath the side pulls.
The belt 10 is made out of 150 Denier polyester and releasably securable elastic basically 66% polyester and 34% Bared EX. The belt is 150 Denier polyester elastic of which the lumbar panel is a part. The side pulls are also 150 Denier polyester elastic. The releasably securable material is generally sold under the trademark Velcro. The hook and wooly portions are applied in opposite positions as shown throughout this description. Where possible, poly cotton binding which is inelastic is secured to the lateral edges of the non-expandable wrap edges 20.
In addition, as to dimensions, the overall dimension from one end to the other of the non-expandable wrap 20 is approximately forty-eight inches. The height of the lumbar panel 12 is approximately nine inches, and the width of the lumbar panel 12 is approximately thirteen inches. The expandable side pulls 14 extend approximately fourteen inches in the unexpanded mode from the central of the two stay pockets 19'. The suspender back straps extend downwardly approximately nine inches from the intersection in the rear, and the suspender securable ends 18 extend an approximate additional four inches. At the other end, the strap extends from the back intersection approximately thirty-six inches when fully let out. By using the adjustable loop buckles 28, this distance can be shortened significantly for the smaller user.
Although particular embodiments of the invention have been shown and described in full here, there is no intention to thereby limit the invention to the details of such embodiments. On the contrary, the intention is to cover all modifications, alternatives, embodiments, usages and equivalents as fall within the spirit and scope of the present invention, specification and appended claims.
