Title: Stiffened brassiere

Description:
FIELD OF THE INVENTION 
     The present invention relates to a stiffened brassiere. 
     BACKGROUND OF THE INVENTION 
     As is known, brassieres comprise two cups which are joined together, two side bands which extend out from the cups and are adapted to be fastened to one another, and two shoulder straps, each of which is attached at one end to one of the cups and at the other to the corresponding side band. Certain types of brassieres are strapless. 
     These brassieres are usually made from pieces of fabric which are stitched together in some suitable way to produce the abovementioned structure. 
     The stiffened brassiere has stiffening elements which are generally positioned along the bottom part of the cup so as to provide a high degree of support for the bust. These stiffening elements usually consist of two curved wires housed in tubular fabric casings which are sewn onto the inside of the brassiere. 
     In DE-U-29810765 such stitched stiffened brassiere is made using at least two superimposed layers of fabric between which the stiffening wires are inserted. 
     Unfortunately, stiffened brassieres are not very comfortable to wear. 
     This is because, in addition to the discomfort caused by the seams joining together the pieces of fabric which are also present in brassieres without underwiring or “soft” brassieres—there is the added discomfort of the underwires and their casings. 
     The seams joining together the pieces of fabric can be uncomfortable because they form irregularities on the brassiere&#39;s surface which can cause irritation when they come into contact with the skin, especially when you consider the relative movements that take place between the brassiere and the skin. 
     The underwires are even more uncomfortable precisely because they are rigid elements which press against the skin through the casings. Moreover, the fact that the casings with the underwires protrude wholly towards the inside of the brassiere just exacerbates the situation. The casing seams, like the other seams, constitute a further source of discomfort. 
     It should also be said that, over time, the seams are subject to wear and can therefore come undone, with the risk of the whole brassiere falling apart. 
     OBJECTS OF THE INVENTION 
     The object of the present invention is to provide a stiffened brassiere which is more comfortable than those of the prior art. 
     This object is achieved by means of a stiffened brassiere comprising two cups which are joined together, two side bands which extend out from the cups and can be fastened to one another, and stiffening wire which reinforce the structure of the brassiere, characterized in that it is made using at least two superimposed layers of fabric between which the stiffening wire are inserted, the two layers of fabric being joined together by means of adhesive bonding and being shaped so as to form the cups and the side bands.

     DETAILED DESCRIPTION OF THE INVENTION 
     With reference to  FIG. 1 , the latter shows an exploded view of some of the components of the brassiere according to the invention. 
     Two layers of fabric, namely a first layer of fabric  1  and a second layer of fabric  2  of the same shape and having a certain degree of elasticity, fitted to be superimposed, are provided. 
     A third layer of fabric  3  is also provided, which is smaller and less elastic than the first and second layers of fabric  1 ,  2 . The third layer of fabric  3  has two adjacent curved edges  4  along which two corresponding curved tubular casings or fourth layer  5  are stitched. A corresponding curved wire  6  with a flattened cross section is inserted into each casing  5  and the ends of the casing are then sewn shut so as to enclose the wire in the casing. 
     The first, second, and third layers of fabric  1 ,  2 ,  3  are placed one on top of the other and are joined together by means of adhesive bonding, inserting the third layer of fabric  3 , with the casings  5  and the wires  6 , between the first and second layers of fabric  1 ,  2  as shown in the sequence of  FIGS. 1 and 2 . This joining by means of adhesive bonding can involve gluing, for example using a thermoadhesive resin which is spread in a suitable manner onto the surfaces of the first, second, and third layers of fabric  1 ,  2 ,  3  which need to be joined together. The adhesively bonded joint can also, as long as suitable fabrics have been selected, be made by heatbonding or heat-fusing the fabric fibres, or by using other similar systems. 
     At this point, as shown in  FIG. 3 , the brassiere structure thus formed is pre-shaped using heat in order to produce two cups  7  in the region of the casings  5  containing the wires  6 . 
     As may be seen in  FIG. 4 , the bra structure with the pre-shaped cups  7  is then cut out so as to produce the final brassiere shape with side bands  8  and with the areas around the cups  7  following the line of the cups themselves. These areas around the cups  7  extend to form two extension pieces  9  on the side opposite the side with the wires  6 . Two extension pieces  10  also extend from the free ends of the side bands  8 , on the same side as the extension pieces  9 . 
     The brassiere structure shown in  FIG. 4  is completed by attaching shoulder straps to the extension pieces  9  and  10  and by applying fastening elements to the ends of the side bands  8  so as to give the finished brassiere shown in  FIG. 6 , where the shoulder straps are denoted by the reference  11  and the fastening elements by the reference  12 . The shoulder straps  11  are attached to the extension pieces  10  by means of rings  13 . The fastening elements consist of eyes attached to one of the two side bands  8  and of corresponding hooks attached to the other side band of the brassiere. The wires  6  are positioned along the bottom part of the cup so as to provide a high degree of support for the bust. 
     Although the brassiere in  FIG. 6  is a stiffened brassiere since it is fitted with the wires  6 , it is still comfortable. 
     First and foremost, there are no external seams and so irritation to the skin is avoided. The only seams present—those on the casings  5  containing the wires  6  are enclosed between the first and second layers of fabric  1 ,  2  and so do not come into contact with the skin. 
     With reference to  FIG. 5 , the fact that the casings  5  containing the wires  6  are compressed between the first and second layers of fabric  1 ,  2  means that their thickness is reduced and, in addition, that they protrude towards the outside as well as towards the inside of the brassiere. All these features make the brassiere more comfortable than those, of the prior art as mentioned in the introduction, in which the casings containing the wires are not compressed and so protrude towards the inside. 
     The flattened shape of the wires  6  reduces the extent to which they protrude and so makes an appreciable contribution to increasing comfort. 
     The fact that the only seams—those of the casings  5  are enclosed between the first and second layers of fabric  1 ,  2  allows them to be protected against wear. 
     It should also be added that since the casings  5  are narrow and enclosed between the first and second layers of fabric  1 ,  2 , they do not need to be secured to the third layer of fabric  3  by strong seams. Furthermore, the wires  6  are securely enclosed within the casings  5  and the two superimposed layers of fabric  1 ,  2 , so that there is no way that they can come out. 
     In order to attach the shoulder straps  11  to the cups  7  and the fastening elements  12  to the side bands  8 , seams can be made which, although external, are extremely unobtrusive. Alternatively, if it is desired not to use seams at all in these finishing operations, other attachment and closure systems—for example heat-bonding systems—can be used. 
     Thanks to the elasticity of the first and second layers of fabric  1 ,  2 , there is no need to use elastic tape along the edges of the brassiere. 
     The brassiere of  FIG. 6  is also very pleasing from the aesthetic viewpoint, given that there are no seams or elastic tapes; this gives the effect of the brassiere being in a single piece. 
     It is of course possible to make variations and/or additions to the embodiment described and illustrated. 
     It would be possible to do without the intermediate or third layer of fabric  3  and the casings  5  sewn to it, positioning the wires  6  directly between the first and second layers of fabric  1 ,  2 . However, the solution illustrated is effective to assemble; moreover, the intermediate or third layer of fabric  3  reinforces the central part of the brassiere. 
     The wires can have a different cross section from the one illustrated, although a flattened cross section of the wires is, as seen above, advantageous. 
     The stiffening wires could consist of silicone material inserted into the casings. 
     In general the stiffening elements can be of any shape and size, they can vary in number and can be placed in any suitable position in the brassiere, depending on the various technical reinforcing requirements. 
     The general shape of the brassiere can be varied to meet different aesthetic and/or functional requirements. The brassiere can also be a strapless brassiere. 
     The present invention having been thus described with particular reference to the preferred forms thereof, it will be obvious that various modifications may be made therein without departing from the spirit and scope of the present invention as defined in the appended claims.
