Abstract

Especially conceived for pregnant women, with the purpose of substantially increasing the perimeter of their fasteners and as an accessory that can be attached thereto, it consists of a band (1) of transparent silicone, provided relatively close to its ends of holes in the that male clasps (6) and female clasps (7) are attached to those commonly used in conventional fasteners, with the end zones (10) and (11) of the strip (1) being located outside the aforementioned clasps folded over the back face of the band (1), covering the bases of the brackets and fixing by welding by heating or ultrasound to the central and majority (1) of the band, covering and protecting the bases of the brackets. This way a transparent extender is obtained that can be used indistinctly with any fastener, independently of the chromatism of the latter.

Description

Extension device for female bras and method of manufacturing it.

Object of the invention

The present invention relates to a extension device, of the type consisting of a complement for a female bra, which allows to increase substantially the perimeter level of the same in certain circumstances, such as in pregnancy.

The object of the invention is to achieve a "universal" extension, valid for any bra, with independence of the color of the latter.

The invention also concerns the method of manufacture of said extension.

Background of the invention

As is known, during the gestation period of women there is a notable increase in the size of their breasts, so that the bras you usually use are they remain small, and consequently temporarily unusable. In order to avoid the investment involved in the purchase of new bras for a relatively short period of time, are known extensions made in a length band appropriate, provided its ends of male and female square brackets, of so that the square brackets are attached to the square brackets bra female, and through her female brackets she does it to the male square brackets, thus achieving the necessary lengthening of the bra, of adjustable magnitude not only because in the bra there are already female brackets multiple, but because the extension also incorporates square brackets female located at different levels and usable selectively

While these extensions solve the problem posed satisfactorily, they present a problem derived from the fact that in many occasions the bra is visible through clothing, such as through cloth of the blouse, which requires for aesthetic reasons that the extender coincides chromatically with the bra.

This brings with it, from the point of view of manufacturing, the need to offer the market a very number considerable of extensions different by their color, at the same time that obliges users to also have a plurality of extensions, especially suitable for different fasteners what do you use.

So the problem inherent in these extensions extends to two aspects: the complexity of its manufacturing and distribution with the consequent increase in costs, and the complication of use derived from the need to have multiple extensions, which in many cases can result difficult to locate.

Description of the invention

The extension device for fasteners feminine that the invention proposes fully resolves satisfactory the aforementioned problem, allowing the manufacture of a single extender for any type of bra, and allowing the user level to have a single extender for an indeterminate group of fasteners.

To do this and more specifically said extender extends into a polyurethane band, specifically transparent silicone, which precisely because of its nature transparent is invisible through any garment of dress, so the extender can be used with any bra regardless of the latter's chromatism.

The aforementioned transparent silicone band incorporates a pair of holes, in transverse alignment, to which they are attached square brackets, for example male square brackets, while relatively close to its other end it incorporates two or more pairs of holes, also in transverse alignment, intended to receive two square brackets, in this case female.

The ends of said band fold over the same hiding and fixing the area of the brackets used normally for fixing, and these extreme folds are solidarity by applying heat or ultrasound to the areas corresponding to the band, so not only the square brackets they are fixed but also their fixing bases are isolated from the user's skin.

According to this structuring, the manufacturing process that is also recommended part of the use of a transparent silicone band or sheet, of adequate dimensions, which in a first operational phase are practice the holes mentioned above, of dimensions suitable to allow both brackets to pass through male as of the female square brackets, up to a limit situation defined by the expansion of its fixing bases, moment in the that the ends of the band are lowered on the base of the square brackets and the definitive fixing of said folds by thermal fusion of the silicone, either by heating or by applying ultrasound to it.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows an elevation view front of an extension device for female bras performed in accordance with the object of the present invention.

Figure 2.- Shows a detail in section longitudinal thereof, according to the cutting line A-B in Figure 1.

Figure 3.- Shows, finally, the four sequences corresponding to the method of manufacturing the extension of the previous figures.

Preferred Embodiment of the Invention

In view of the figures outlined you can be observed as the extension cord that is recommended is constituted to from a band or sheet (1) of transparent silicone, rectangular, of appropriate length to that provided for the extension, band (1) provided relatively close to one of its ends (2) of a pair of holes (3) in transverse alignment, while that in a situation of greater distancing from his other end (4) incorporates two pairs of holes (5), also of reduced diameter just like the holes (3) above cited.

The holes (3) are intended for coupling of respective male square brackets (6), conventional, of the type commonly used in any bra, while the holes (5) are in turn intended for coupling of respective female square brackets (7) as shown in the  second sequence of figure 3.

Once male square brackets (6) and female square brackets (7) have been implanted in the holes (3) and (5) of the band (1), with its operational sector oriented towards what should be the outer face of the extension, the extreme zones (2) and (4) of the band (1) fold towards the rear face of said band, such as the third sequence of figure 3 shows, specifically the zones referenced with (8) and (9), configuring extreme sectors (10) and (11) double-walled, as seen especially in the Figure 2, where the transparent silicone of the two layers is intimately linked together by heat application or by ultrasonic application, thus achieving a stiffening of the extreme areas of the extension where place the brackets, which prevents breakage or tearing of the silicone, and where also the bases of the brackets both male (6) and female (7) are embedded in the silicone, perfectly fixed and no possibility of coming into contact with the body of the user.

Claims (2)

1. Extension device for female bras, of the type that constitute a complement of the bra, intended to increase the perimeter dimension of the latter and provided at the ends of male brackets and equal and complementary female brackets that finish off the ends of the bra , it is characterized in that it consists of a transparent silicone band, with its folded ends defining double-walled sectors in which the bases of the male square brackets and the female square brackets are embedded, which emerge outside the said band through respective small diameter holes. 2. Method of manufacturing the extender for female bras of claim 1, characterized in that it is part of a rectangular and relatively elongated transparent silicone band, band (1) in which relatively close to one of its ends is established at at least one pair of holes (3) in transverse alignment, while in a situation of slight greater proximity to its other end, at least two transverse alignment of holes (5) are established, then coupling into the holes (3) of respective brackets (6), preferably male, and in the holes (5) of respective square brackets (7), preferably female, having then provided that the end areas (8) and (9) of the silicone band located outside those mentioned holes (3) and (5), fold back on the back side of the band itself, covering the bases of the square brackets, and definitely looking at such a retracted situation. by welding by heat application or by ultrasound.
