ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to garments and sanitary protections which can be tightly worn on a body part or articulation to be protected or aided in its mechanical action and more particularly to an elastic waistband with transverse stiffeners and tautness adjustment lacings.
BACKGROUND OF THE INVENTION
In making elastic sanitary implements for aiding the mechanical action of articulations, in order to recover their full functionality after injuries or as a form of prevention in performing sporting activities involving relatively high stresses on muscles and/or articulations, it is necessary to ensure, besides the comfort of use, a good adjustability of the elastic tautness.
The conventional tubular elastic sanitary protections are not capable of satisfying the adjustability requirement and can be produced only in a series of relatively standardized sizes.
For uses absolutely requiring the possibility of adjustment, both for the effectiveness of the elastic guard and for comfort, a common lacing must be used for joining two opposite edges of an elastic sanitary band or garment so as to allow to control the tautness and/or to modulate it along its length. The adjustment of the tautness by loosening or tightening the lacing is a wearisome and not very practical operation. In order to obviate the laboriousness of a lacing, use is often made of the so-called “Velcro”® wherein a strip material having a population of tiny hooks fasteners is sewn on the surface of an edge of the sanitary protection, garment or footwear and may be pressed into an anchoring engagement on the surface of a cooperating strip of piled fabric. The range of adjustment of the tautness depends obviously upon the size of the area of piled fabric available for anchoring the hooked part of the Velcro, that is either sewn over the opposite edge of the elastic implement or on the same edge thereof, in which case the band of Velcro with the tiny hooks is first passed through a eyelet of the opposite edge of the implement and pulled back to anchor it on the sewn pad of piled fabric. In case Velcro fasteners are used for closing and tightening a substantially tubular sanitary protection or garment, the proper positioning of the sanitary protection around the part of the body to be protected is made difficult by the need of elastically stretching one edge only of the implement before joining the two cooperating parts of the Velcro fastener, often resulting in accidental slippings of the sleeve or bandage, which must be repositioned after fastening it.
When, as it is often the case, these sanitary implements, bandages or garments are wholly or at least partially made of an elastic fabric comprising textile yarn of a natural or synthetic fiber, interwoven by knitting or other suitable weaving techniques with elastomeric yarns so as to produce an elastic fabric, paddings of a suitable fabric (pile) must be applied in the areas where the hooked Velcro material, sewn in proximity of a superimposable edge of the elastic fabric may be anchored. This need to provide for suitable Velcro anchoring pads arises from the fact that the elastic fabric cannot withstand repeated engagements with the tiny hooks of the Velcro material, which would quickly and irremediably damage the elastic fabric.
On the other hand, the need to have Velcro anchoring pads of a suitable pile sewn on the outer surface of the elastic implement implies the presence of local bumps and stiffenings which may have wearisome outcomes, especially in case of prolonged use of these implements for dynamic activities.
Furthermore, a predefined position of these anchoring pads Velcro limits the possibility to adjust tautness of the garment or sanitary protection and retail shops of these implements must keep an adequate stock of different sizes.
When, as it often occurs, the sanitary implement comprise stiffeners or reinforcements permanently or removably inserted into dedicated pockets or housings, the ability of an elastic bandage of a certain size to fit different situations (sizes) is even more reduced, in spite of an ability to stretch. In fact, the requirement of properly positioning of such stiffeners or supports with respect to the articulation or limb to be supported or immobilized practically makes the implement hardly suitable to fit body conformations or even marginally different sizes, thus forcing, especially in these cases, to keep a large stock of close sizes.
The keeping of large stocks of differently sized articles has a precise cost in terms of working capital tied up, which is especially critical for specialized commercial enterprises with a relatively small volume of business.
In a prior patent application PCT/IT98/00054 filed on Mar. 17, 1998, and claiming the priority of Italian Patent Application No. VA/97/A0012 filed on Apr. 16, 1997, a special elastic fabric directly engageable by Velcro fasteners and a number of sanitary protection implements made with such a special elastic material having normal unlimited ability to fit people of different body sizes are described. In particular, an elastic waistband having one end in the form of two independently stretchable and anchorable triangular tail portions is described (FIGS.

In the document PCT/IT98100055 filed on Mar. 17, 1998, and claiming the priority of Italian Patent Application No. VA/97/A/0006 filed on Mar. 18, 1997, a tightening and elastic tautness adjustment device for a garment of sanitary protection or alike implement to be tightly worn, is described. The article is composed of at least a first elastic textile band formed of a plurality of parallel elastic strips (

) extending from a first edge of the garment or sanitary protection and having their free ends sewn onto a first strip (
8
) of hooked Velcro material and at least a second elastic textile band similarly formed of a plurality of parallel elastic strips (
2
′) extending from a second edge of the garment or sanitary protection opposed to the first edge, and interlaced with the parallel strips (
2
) of the first band, their free ends being sewn onto a second strip of hooked Velcro material.
The mutually interlaced multistrip elastic bands are stretchable by pulling apart the two Velcro strips to be eventually anchored on the outer surface of the implement in the desired position.
For certain affections and application, the elastic tautness of a sanitary implement is not a sufficient condition of effectiveness and the implement must include stiffening members for exerting a proper supporting action. This is the case of a waistband for providing an adequate support of the trunk in case of deviar lumbar affections and during recovery periods from spinal surgeries and so forth.
In cases like these, it is even more important to ensure a perfect fit of the implement and a correct disposition and orientation of the stiffening inserts of the waistband. The known implements tough having a limited ability to be adjusted so as to best fit the waist size of the wearer, they achieve this by a wealth of lacings, Velcro fasteners of difficulty manageability by the wearer itself, which often requires the help of someone else to properly put on the implement in an effective way.
OBJECT AND SUMMARY OF THE INVENTION
It is the main object of the present invention to provide an elastic waistband provided with stiffeners and tautness adjusting means having a structure and a configuration that beside ensuring an ability to fit perfectly a practically unlimited range of body sizes is also easily adjusted by the wearer itself through simple actions while ensuring, in any situation of adjustment, a most appropriate disposition and orientation of the stiffening inserts present in the waistband.
Fundamentally, the waistband of the invention has primary multiple elastic tautness adjusting means and secondary multiple elastic tautness adjusting means, the coordinated adjustment of which provides for an effective correction of the disposition and orientation of the transverse stiffeners incorporated in the elastic
