Abstract

The article (10) has an interior part (14) for forming underwear e.g. slip or string, and an exterior part (12) for forming a garter belt, where the article is made of polyamide or elastane. The interior part and the exterior part are connected to each other by a tubular belt (16), where the interior part, exterior part and the tubular belt are formed from a single fabric by circular knitting. The belt includes large proportion of elastane than the exterior part or interior part. An independent claim is also included for a method for manufacturing a lingerie article.

Description

The invention relates to a feminine lingerie article for the lower body, of the slip type (or panty) or string. More specifically, the invention relates to a lingerie article having an inner portion forming a panty-type undergarment or thong and an outer portion forming a garter belt.

Usually, the slip-on or thong undergarment and garter belt are two separate pieces that can be worn together or separately.

It is also known to directly connect suspenders to the belt of the undergarment which then serves as a garter belt ( GB1130473 or GB634618 ).

However, in this case, we lose the visual effect rendered by a set of two parts formed of an undergarment on the one hand and a garter belt on the other hand, which are worn superimposed.

The object of the present invention is to provide a lingerie article forming both a slip-on or thong-type undergarment and a garter belt and which is made simply and quickly.

For this purpose, according to the present invention, the lingerie article is characterized in that the inner portion and the outer portion are connected to each other by a tubular belt, and in that the inner portion, the portion outer and the tubular belt are from the same piece of knit made by circular knitting.

Advantageously, the tubular belt consists of a lapel of the knit piece, the two thicknesses of the knit of the lapel being retained one by the other by at least one hooking thread.

In this way, it is understood that by virtue of the fact that the inner part and the outer part come from the same tube forming a single piece of knit made by circular knitting, it is very easy to obtain a lingerie article of the seamless type, at the same time becoming and comfortable.

1. a) le tricotage d'un premier tronçon de tube destiné à former la partie extérieure,
2. b) la réalisation d'un revers par retenue du premier tronçon de tube et par tricotage des deux épaisseurs du tricot du revers,
3. c) l'accrochage du revers tricoté au moyen d'un fil d'accrochage de façon à former la ceinture tubulaire,
4. d) le tricotage d'un deuxième tronçon de tube destiné à former la partie intérieure.

The invention also relates to the method of manufacturing a lingerie article comprising an inner portion forming a panty-type undergarment or thong and an outer portion forming a suspender belt. According to the invention, a single knit piece is knitted on a circular knitting machine, said knit piece being obtained by the following steps:

1. a) knitting a first tube section intended to form the outer part,
2. b) the making of a lapel by retaining the first section of tubing and knitting the two thicknesses of the knit of the lapel,
3. c) the hooking of the knitted lapel by means of a hooking thread so as to form the tubular belt,
4. d) knitting a second tube section to form the inner part.

Overall, thanks to the solution according to the present invention, it is possible to provide a manufacturing method that is simple to implement since a single piece of knitted fabric is produced which makes it possible to obtain both the inner part forming an undergarment of slip type or string and the outer part forming a garter belt, so without having to connect two separate knit pieces, for example by sewing.

This solution also has the additional advantage of allowing, in addition, rapid manufacture of a lingerie article which has a neat appearance due to the absence of seam between the inner part forming a slip-type or string-type undergarment. and the outer part forming a garter belt.

Other advantages and characteristics of the invention will become apparent on reading the following description given by way of example and with reference to the appended drawings in which:

• the figure 1 is a partially transparent projection view from the front of a lingerie article according to the invention forming both a panty and a garter belt;
• the figure 2 is a sectional and perspective view along the II-II direction of the figure 1 ;
• the figure 3 is a flat unfolded view of the tubular knit piece obtained at the output of the knitting machine, making it possible to produce the lingerie article of the figure 1 ,

• the figure 5 is a flat unfolded view of the tubular knit piece obtained at the output of the knitting machine, making it possible to produce the lingerie article of the figure 4 ; and
• the figure 6 represents the lingerie article as it is worn, in front view.

The lingerie article 10 of the figure 1 has an outer portion 12 forming a garter belt, an inner portion 14 forming a panty and an upper portion, connecting the outer portion 12 to the inner portion 14, forming a tubular belt 16.

As will be detailed in the following, the inner portion 14, the outer portion 12 and the tubular belt 16 come from a single piece of tubular knit. Such an article generally called "seamless" type surrounds its tubular part of the body portion to cover without side seam, which would be unsightly and would cause some discomfort when it comes to a lingerie article worn within the skin, since it then has a certain restraint to be retained by itself on the body.

In addition to the parts 12, 14 and 16 entirely from the knit piece, the final lingerie article 10 includes accessories and ornaments: the four garters 18 equipped with their tongs 20 have been attached by a seam 22 on the free edge of the outer portion 12, on the four points defined between two of the four notches 121a, 121d, 121g and 121p bordering the outer portion 12 forming garter belt. Also, the four notches 121a, 121d, 121g and 121p bordering the outer portion 12 forming garter belt and the four notches 141d, 141g, 142d, 142g bordering the inner portion 14 forming slip to form the leg openings may be coated of a visible bias 24 on the figure 6 .

In order to adapt easily to all anatomies and all forms of underpants (high, low or intermediate) while allowing to retain with sufficient restraint the article 10 on the body, the tubular belt 16 has a springback more important than the outer part 12 and the inner part 14.

For this purpose, according to a preferred arrangement, the inner part 14, the outer part 12 and the tubular belt 16 are entirely made in the same mesh and the tubular belt 16 has at least one less wire than the outer part 12 and the part Inside 14.

For example, said knit piece comprises three son among which at least one elastic thread except in the belt 16 which has only two son including said elastic thread.

For example, the lingerie article 10 is made of polyamide and elastane, the tubular belt 16 having a greater proportion of elastane than the inner portion 14 and the outer portion 12.

• deux fils de polyamide, chacun étant formé de 52 brins pour un total présentant une masse linéique de 78 dtex, et
• un fil de polyamide /élasthanne composé d'une âme ou fil guipé d'un brin d'élasthanne et de deux fils de couverture ou de guipage en polyamide présentant chacun 7 brins pour un total présentant une masse linéique de 29 dtex.

The following threads can be used, mounted together on each fall of the knitting machine:

• two polyamide yarns, each consisting of 52 strands for a total having a linear density of 78 dtex, and
• a polyamide / elastane yarn consisting of a core or yarn wrapped with one elastane strand and two polyamide covering or covering yarns each having 7 strands for a total having a linear density of 29 dtex.

According to an advantageous arrangement, the knitting of the zones of the knit piece intended to form the inner part 14, the outer part 12 and the tubular belt 16 is entirely made of the same mesh. Preferably, so that the belt 16 has a greater elasticity than the outer portion 12 and the inner portion 14, the reverse forming the tubular belt 16 has at least one wire less than the first tube section and the second section of tube in which respectively the outer part 12 and the inner part 14 are formed.

Thus, in the example of the composition presented above, one of the two polyamide threads is removed during the knitting of the lapel so that in the tubular belt 16 the larger proportion of elastane combined with the absence of one of the two polyamide yarn makes it possible to obtain a knit with a greater springback.

These choices of materials are given for illustrative purposes, the present invention being applicable to all traditional materials. Are conceivable for the realization of these lingerie articles: continuous yarn (textured or flat) or spun natural, artificial or synthetic fibers (polyester, polyamide, acrylic, cotton, silk, viscose, acetate ...) and their mixtures.

1. a) le tricotage d'un premier tronçon de tube 112 dont une zone supérieure est destinée à former la partie extérieure 12 (sur la figure 3, ce premier tronçon de tube débute par tricotage le long de la bordure 112a jusqu'à une ligne d'accrochage 112b) ,
2. b) la réalisation d'un revers 116 par retenue du premier tronçon de tube 112 et par tricotage des deux épaisseurs 116a, 116b du tricot du revers 116,
3. c) l'accrochage des deux épaisseurs 116a, 116b du revers 116 tricoté à l'emplacement de la ligne d'accrochage 112b au moyen d'un fil d'accrochage de façon à former la ceinture tubulaire 16,
4. d) le tricotage d'un deuxième tronçon de tube 114 dont une zone supérieure est destinée à former la partie intérieure 14, à partir de la ligne d'accrochage 112b et jusqu'à une bordure 114a.
   Lors de l'étape b), la pièce de tricot en cours de réalisation est attachée afin de stopper momentanément sa descente dans l'organe de réception du tube tricoté, ce qui permet, lorsque le tricot se poursuit, de former un revers, c'est-à-dire, deux épaisseurs de tricot se faisant face entre lesquelles se trouve un pli. Avant le début du tricotage du deuxième tronçon de tube 114 à l'étape d), on relâche alors la pièce de tricot en cours de réalisation afin de permettre de reprendre sa descente dans l'organe de réception du tube tricoté.
   De cette façon, comme il apparaît sur la figure 3, où le tube a été représenté déployé (en réalité les lignes droite et gauche de la figure 3 sont confondues), avec le deuxième tronçon de tube 114 placé à l'intérieur du premier tronçon de tube 112, on obtient une double structure tubulaire. En effet, on dispose d'un premier tronçon de tube 112 extérieur et d'un deuxième tronçon de tube 114 intérieur, plus long, le revers 116 formant la ceinture tubulaire 16 constituant un bourrelet reliant les deux tronçons de tube 112, 114 le long de leur bordure supérieure à l'emplacement de la ligne d'accrochage 112b.
   Après dégagement de la pièce de tricot 110 de la machine à tricoter circulaire, on met en oeuvre en outre les étapes suivantes :
5. e) le découpage du premier tronçon de tube 112 selon le contour du porte jarretelles délimité par les échancrures précitées (échancrure antérieure 121a, échancrure droite 121d, échancrure gauche 121g et échancrure postérieure 121p délimitant un contour fermé) et le découpage du deuxième tronçon de tube 114 selon un contour fermé destiné à former les ouvertures 144g et 144d du sous vêtement, selon les échancrures antérieures droite et gauche 142d, 142g, et les échancrures postérieures droite et gauche 141d, 141g, et l'entrejambes 143 du sous vêtement, selon deux lignes de fond 141f et 142f, et
6. f) la couture entre les deux lignes de fond 141f et 142f formant deux portions du contour découpé dans le deuxième tronçon de tube 114 afin de former l'entrejambes (ou fond) 143 du sous vêtement.

During the manufacturing process, for example on a machine SANTONI SM 8-8 with eight drops, with a gauge of size 28 and having a diameter of 13 inches or 33 centimeters, the following steps are carried out (see figures 2 and 3 ) for producing the single knit piece 110:

1. a) knitting a first section of tube 112, an upper zone of which is intended to form the outer portion 12 (on the figure 3 this first section of tubing begins by knitting along the border 112a to a hooking line 112b),
2. b) the production of a lapel 116 by retaining the first section of tube 112 and by knitting the two thicknesses 116a, 116b of the reverse knit 116,
3. c) hooking the two thicknesses 116a, 116b of the knitted lapel 116 at the location of the fastening line 112b by means of a fastening thread so as to form the tubular belt 16,
4. d) knitting a second section of tube 114, an upper region of which is intended to form the inner portion 14, from the hooking line 112b and to a border 114a.
   In step b), the piece of knitting fabric is attached to stop momentarily its descent into the receiving member of the knitted tube, which allows, when the knitting continues, to form a lapel, c that is, two layers of knit facing each other between which there is a fold. Before the beginning of the knitting of the second section of tube 114 in step d), then release the piece of knitting in progress to allow to resume its descent into the receiving member of the knitted tube.
   In this way, as it appears on the figure 3 , where the tube has been shown deployed (actually the right and left lines of the figure 3 are combined), with the second section of tube 114 placed inside the first section of tube 112, a double tubular structure is obtained. Indeed, there is a first section of outer tube 112 and a second section of inner tube 114, longer, the reverse 116 forming the tubular belt 16 constituting a bead connecting the two tube sections 112, 114 along from their upper border to the location of the snap line 112b.
   After disengagement of the knit piece 110 from the circular knitting machine, the following steps are further carried out:
5. e) the cutting of the first section of tube 112 according to the contour of the garter belt delimited by the aforementioned indentations (anterior notch 121a, right notch 121d, left notch 121g and posterior notch 121p delimiting a closed contour) and the cutting of the second section of tube 114 in a closed contour intended to form the openings 144g and 144d of the undergarment, according to the left and right anterior notches 142d, 142g, and the right and left posterior notches 141d, 141g, and the crotch 143 of the undergarment, according to two baselines 141f and 142f, and
6. f) the seam between the two bottom lines 141f and 142f forming two portions of the contour cut in the second tube section 114 to form the crotch (or bottom) 143 of the undergarment.

Thus, after the aforementioned cutting step, the end portion of the first tube section 112 which includes the edge 112a and the end portion of the second tube section 114 which has the edge 114a are spaced apart.

Advantageously, during steps b) and d) of knitting the first section of tube 112 and the second section of tube 114, a different knit mesh is used at the location of cutting marks serving as markers during step e) cutting. On the figure 3 , for the first section of tube 112 intended to form the outer portion 12 (garter belt), these cutting marks correspond to a continuous zone 112c whose edge coincides with the notches 121a, 121d, 121g and 121p. For the second section of tube 114 intended to form the inner portion 14 (slip), these cutting marks correspond to lines coinciding with the indentations 141d, 141g, 142d and 142g and the two bottom lines 141f and 142f.

Alternatively, it is conceivable to make these cutting marks with an additional yarn knitted in relief or having an appearance, in particular a different color,

The cutting is performed by rapid rotation of a cutting tool, which creates a local melting of the material, whereby the stitches of the knit are stopped at this location.

On the figures 4 and 5 there is shown another lingerie article 10 'according to the invention and the knit piece 110' making it possible to obtain it. Elements identical to those of figures 1 and 3 bear the same reference signs.

• les échancrures 141d', 141g', 142d' et 142g' qui sont alors plus marquées et qui remontent plus près de la ceinture tubulaire 16 que dans le cas du slip, et
• les deux lignes de fond 141f' et 142f' qui sont alors plus étroites et positionnées différemment que dans le cas du slip, pour former un entrejambes 143' plus étroit.

In this case, the outer portion 12 forming garter belt is unchanged, but the shape of the inner portion 14 'then forming a string is modified:

• the indentations 141d ', 141g', 142d 'and 142g' which are then more marked and which go back closer to the tubular belt 16 than in the case of the underpants, and
• the two bottom lines 141f 'and 142f' which are then narrower and positioned differently than in the case of the underpants, to form a crotch 143 'narrower.

It is therefore understood that the tubular knit piece 110 'is similar to the knit piece 110 of the figure 3 allowing the realization of the panty brief, the only difference residing in the position of the cut marks for the second section of tube 114 intended to form the inner portion 14 '(string), which delimits openings 144g', 144d 'more wide and higher than for the underpants. These cutting marks correspond to lines coinciding with the indentations 141d ', 141g', 142d 'and 142g' and the two bottom lines 141f 'and 142f'.
