Abstract

The knitted belt (1) according to the invention comprises regions (4-8) having a different elasticity over the circumference thereof, wherein some of the regions (5, 6) corresponding to relatively hollow regions (13, 11) of a user's waist have a maximum level of local elasticity, in particular in a central back region (6) and two lateral front regions (5) corresponding respectively to the spine and to the tendons linking the wearer's rectus abdominis with the external oblique muscles.

Description

Multi-elastic band and method of making the same

The present invention relates to self-contained belts (eg, self-contained corset-like belts), or more particularly to garment or underwear belts, ie belts that are integrally formed with clothing. More specifically, the invention relates to belts knitted on circular knitting machines or flat knitting machines, in particular by the knitting method known as the "seamless" knitting method.

The belts currently available on the market are uniform in elasticity in the longitudinal direction (circumference) of the belt. There are so-called "multistage" belts, which have two or more different elasticities in the height direction. However, these straps do not particularly conform to the anatomy of the human body, causing inconvenience and discomfort to the wearer.

However, document EP1031292 already discloses a belt with regions of different elasticity in the circumferential direction, in fact the side of the belt is less elastic than the front or the back of the belt, by introducing more or less Yarns with elasticity can achieve this difference in elasticity. While this suggestion helps improve wearer comfort, it has proven to be insufficient.

It is an object of the present invention to make better use of the wearer's morphology in order to create a better fitting belt.

According to the invention, the object of the invention is achieved by a method according to which areas on the waist of the wearer are first identified which are relatively sunken compared to areas which are relatively tight, and by placing local The strap is constructed in the area of greatest elasticity.

In fact, it has been observed that the depressed area is located mainly on the back along the spine on the one hand, and on the front side on the other hand at the tendons connecting between the rectus abdominis and the left external oblique and between the rectus abdominis and the At the tendon between the right external oblique muscles. Therefore, it is advantageous to have the most elastic zone among these three zones. Conversely, in areas other than these areas, it is advantageous to reduce the elasticity. This construction ensures optimal and proper support as well as comfort.

The invention can be applied to belts that are woven or knitted into different elastomers of different elasticity that are sewn to each other, however, more specifically, the object of the invention is to provide a belt that is woven or knitted into a single piece, where the During or after manufacture, different regions of the belt are made to have different elasticities by special means.

According to the present invention, different regions of the integral strap may be made to have different elasticities according to any of the following methods comprising:

- Knitting the belt, especially jersey, varies the elasticity of the belt by varying the stitch structure and/or the type of yarn used, depending on the desired area.

- Knitting holes in the strap, depending on the area, different elasticity of the strap by varying the size of the hole (the larger the hole, the less elastic it will be).

- Partially knitting the belt with elastic yarns that make the knitted fabric elastic and burning the elastic yarns of the belt according to the areas, ie selectively removing the elastic yarns in selected areas.

Next, resin-based polymers and silicone-based polymers are printed on the surface of the knitted fabric differently according to the area. It is advantageous to print a similar pattern along the strip, but in areas where more elasticity is required, to print more densely, or to print in thicker or larger lines. These patterns can advantageously consist of letters, especially letters commonly used, reminding or indicating clothing brands.

The invention also relates to the tapes obtained by the method of the invention. Thus, the belt for a wearer or a type of wearer comprises, along its circumference, zones of different elasticity, some zones having a local maximum elasticity, said zone of local maximum elasticity being in contrast to the relatively concave region of the wearer's waist of the belt. corresponding to the area.

Indeed, said zone of local maximum elasticity may comprise at least one central back zone and two transverse front zones corresponding respectively to the wearer's spine, tendon muscles connected between the rectus abdominis and the external oblique muscles. The width of these regions is relatively small.

Other features and advantages of the invention will become apparent from the following description. Reference will be made to the following drawings, in which:

FIG. 1 schematically shows a belt according to the invention in perspective with different elasticities in different regions.

Figure 2 shows schematically in section a belt according to the invention around the abdomen of a wearer (the belt is shown schematically at some distance from the wearer's waist, but it is understood that the belt actually adjoins the waist).

FIG. 3 shows a variant of FIG. 2 .

Fig. 4 shows in the same figure different printed patterns according to the invention allowing differential elasticity in different areas.

The strip 1 is in the form of knitted tube sections. It may consist of a separate knitted belt or, most often, the upper part of a garment or underwear (not shown, eg briefs or boxer shorts). In fact, it is known to make, by knitting, belts at the top of panties, pantyhose, shorts, boxer shorts etc. with hems (for example with plate hooks). The belt 1 shown comprises a front side 2 and a back side 3 constituting a single piece. The front side 2 comprises a central belly area 4 surrounded by two transverse belly areas 5 . The back 3 comprises a central back area 6 surrounded by two lateral back areas 7 . The side areas 8 form the sides, connecting the transverse belly area 5 and the transverse back area 7 together.

Figure 2 shows the same belt 1 around the waist of a wearer 10 in section. The waist presents a recessed area 11 at the wearer's spinal passage, which may or may not itself be surrounded by two other recessed areas 12 (recessed areas 12 are shown in FIG. 2 but not in FIG. 3 ). In addition, two depressed tendon regions 13 are included between the rectus abdominis muscle on the front of the wearer (in the front central portion) and the external oblique muscles on the abdomen (extending toward the side). According to the invention, the strap 1 has zones 6 and 5 of increased elasticity (+++ or ++), corresponding to the depressed zones 11 and 13, and conversely, in other, more compact zones, zones 8 and 4 of reduced elasticity (+). Regions 6 and 5 are regions with local maximum elasticity. It is possible to have a zone 7 corresponding to zone 12 with increased elasticity (++), but since this zone 7 adjoins zone 6 (+++), only one side of this zone 7 has a maximum local elasticity.

In FIG. 3 , the strip 1 does not have an intermediate region 7 since there is no recessed region 12 or because the recessed region 12 is not considered.

Since the recessed area is not very large, the corresponding area 6 or 5 is also not very large. However, due to the presence of the dimples, these areas are sufficiently elastic to provide the desired comfort to the wearer by making the areas less in contact with the wearer's skin highly elastic.

The difference in elasticity of different regions of elasticity can vary greatly from one region to another, or, conversely, can have a continuous transition.

In a different way for obtaining this different elasticity, it is advantageous to print an elastomer (eg resin or silicone) on the surface to provide elasticity. The printing is advantageously carried out according to the pattern, the printing density being increased in areas which should have more elasticity. Figure 4 shows examples A, B, C, D, E, F of the pattern, the pattern running along the belt, and showing the density varying according to the area to make the area elastic +, ++ or +++. The pattern can be a purely geometric shape (eg, patterns E or F), where the thickness of the pattern and/or the width of the deposited lines increases in regions of enhanced elasticity. The pattern may advantageously be in the form of letters, advantageously replicating a brand of clothing (as shown in pattern A, B or C), in which the letters DIM are repeated at greater or lesser intervals to vary the elasticity. These letters can be combined with secondary figures (for example, the lines visible in patterns A, B, or C), or primary figures (such as the honeycomb in pattern D). Advantageously, printing is performed by screen printing or by deposit transfer.

In this way, a marked and aesthetically pleasing band is obtained, the marking of the band contributing to increased comfort by defining zones of different elasticity according to anatomical principles.
