Belt self-adjustable to the waist

Abstract

A belt that is self-adjustable to the waist comprises a long flexible strap ( 1 ), which constitutes the belt itself, with a cross-section formed by a complete flattened loop with a free gap ( 2 ), like a flattened tube, one of the ends of the strap being folded ( 3 ) and normally receiving at least one belt loop ( 4 ) and a conventional coupling device ( 5 ) suitable for providing means for quickly adjusting and coupling or uncoupling the other end of the strap ( 1 ); the strap ( 1 ) is split into two parts near the fold ( 3 ), forming two adjacent ends ( 6 ) and ( 7 ), inside which an elastic strap ( 8 ) and a guide tongue ( 9 ) operate and together allow a variable belt diameter to be achieved after the belt is adjusted to the user's body. This effect can also be obtained with other arrangements, i.e. coupling the buckle ( 5 ) to other elastic means ( 11 ), ( 25 ) and ( 26 ), which also cooperate such that the belt ( 1 ), after being adjusted to the user's waist, can be automatically adjusted, the circumference of the belt increasing or decreasing sufficiently to provide the comfort desired when the user changes position, mainly when sitting down and standing up again, eliminating the uncomfortable sensation of a tight belt.

1 . Belt self-adjustable to the waist, the type manufactured in leather, forming a long flexible strap which constitutes the belt itself, with a cross-section formed by a complete flattened loop with a free gap, like a flattened tube, as well as one of its end, after being folded receives, normally, at least one belt loop and a conventional coupling device which, in turn, can be a simple buckle or a more complex closure; however, any of them may provide sufficient means for adjusting and quickly coupling or uncoupling the other end of the strap; characterized in that the strap is split at a point next to the fold, forming two adjacent ends and, one on the side of the fold and, on this side, said end receives in its free gap the end of an elastic strap and the end of a guide tongue, the latter having its other end freely positioned within the gap on the other end of the strap, inside of which it is also fixed the other end of the elastic strap which, in turn, is held with sufficient tension to traction the ends and of the strap and keeping them together until a stronger stretching force is applied to the belt. 
     
     
         2 . Belt self-adjustable to the waist, according to  claim 1 , characterized in that, in another preferred embodiment, the elastic strap and the guide tongue are interconnected at their ends, while their opposite ends are fixed, respectively, within the end and within the end, both being embedded in the gap of end. 
     
     
         3 . Belt self-adjustable to the waist, according to  claim 1 , characterized in that the guide tongue is formed by a continuation of the anterior or posterior wall of the hinge region which configures the buckle fastening point. 
     
     
         4 . Belt self-adjustable to the waist, according to  claim 1 , characterized in that the first constructive version comprises two movable elements, also in the form of straps, one elastic inner element and an outer sliding finishing element which, besides being joined together by one of their ends, also attach the belt loop and the coupling device, while on the opposite side they are coupled to the corresponding end of the flexible strap, these couplings, in the case of the finishing element slides and compensates for the stretching and shrinking of the elastic inner element. 
     
     
         5 . Belt self-adjustable to the waist, according to  claim 4 , characterized in that the outer sliding finishing element is a folded strap which has the same width as the flexible strap and, on the folded side, forms a volute which is complete with a transversal seam, which configures and articulated point for fixing the coupling device, while at the opposite ends, parts and of the finishing element extend, respectively, along the outer and inner faces of the flexible strap which, in turn, at this portion, has a longitudinal slot where a transverse pin runs through, having its ends fixed in said parts and, wherein said pin and slot form the limiting means for the stretching and shrinking course of the elastic element. 
     
     
         6 . Belt self-adjustable to the waist, according to  claim 4 , characterized in that the elastic element has one end fixed by the seam, while on the other side its parts and extend, respectively, along with the outer and inner faces of the flexible strap and are joined by transverse seams. 
     
     
         7 . Belt self-adjustable to the waist, according to  claim 4 , characterized in that the elastic element is a single strap, having its ends equally anchored, respectively, on either side of the strap and the device. 
     
     
         8 . Belt self-adjustable to the waist, according to  claim 4 , characterized in that, the parts and are sufficiently extended beyond the pin to maintain it always embedded within said slot. 
     
     
         9 . Belt self-adjustable to the waist, according to  claim 1 , characterized in that the second constructive version has the corresponding end of the flexible strip folded to the inside forming a short opposed portions which, in turn, configures an extreme volute, in which passes the pivot axis of the device and also forms the fixing point for the belt loop, wherein said volute is longitudinally elongated enough to form a longitudinal gap (Y) for the displacement of the device; further comprises an elastic inner element fixed between opposed portions and the flexible strap, as well as a coupling connecting the corresponding end of said elastic element with the axis of the device which, in turn, is normally kept pulled inwards up to the point (a) by said elastic element, which is capable of stretching to the point (b) when the device is forced out (f). 
     
     
         10 . Belt self-adjustable to the waist, according to  claim 9 , characterized in that the elastic element is a folded strap forming two opposing parts and has an end that passes through a transverse slot of the coupling which, in turn, has the other curved end coupling with the axis, while opposite ends of the opposing portions are fixed by a seam between the opposed parts of the portion and the strap, providing other fixing points with side seams between said parts of the opposing portion and the strap which, in this case, maintains the elastic element free, so that the same can extend and shrink having only the seam and the axis as a support point. 
     
     
         11 . Belt self-adjustable to the waist, according to  claim 1 , characterized by comprising a volute which is an additional piece, thinner that the flexible strap. 
     
     
         12 . Belt self-adjustable to the waist, according to  claim 11 , characterized in that the additional part of the volute is a thinner laminate elastic component.
