Description

(1) We shall now describe, as a non-limitative example, one possible embodiment of the disclosure, with reference to the attached drawings, on which identical or similar reference numbers indicate identical or similar elements or sets of elements:

(2) FIG. 1 is a rear view of the boxer shorts according to the embodiment of the present disclosure;

(3) FIG. 2 is a front view of the boxer shorts according to the embodiment of the present disclosure;

(4) FIG. 3 shows a hysteresis curve for the waistband of a pair of boxer shorts according to the prior art and a hysteresis curve for the waistband of a pair of boxer shorts according to the present disclosure.

(5) With reference now to FIG. 1 and FIG. 2, a pair of boxer shorts (1) according to the embodiment of the disclosure includes a pants portion (2) made of a textile fabric. The pants portion (2) includes: A front part (3) that includes a central panel (4) intended to cover the genital organs of a wearer, and two front side parts (5a) and (5b), each of which is intended to cover the front surface of one leg of the wearer; A rear part (6) that includes a rear panel (7) intended to cover the buttocks of the wearer, and two rear side parts (8a) and (8b), each of which is intended to cover the rear surface of one leg of the wearer; and A middle part (9) intended to cover the inner surfaces of the legs forming the crotch of the wearer, and including a part (10) intended to cover the groin area of the wearer, with the middle part thus extending over the front part (3) and enclosing at least part of the central panel (4).

(6) The rear panel (7) and the middle part (9) display a degree of expandability in the upward direction and in the widthwise direction of 145% for a stretching stress of 15 cN, while the front part (3) and the two rear side parts (8a) and (8b) display a degree of expandability in the upward direction of 20% for a stretching stress of 15 cN and a degree of expandability in the widthwise direction of 80% for a stretching stress of 15 cN.

(7) The rear panel (7) and the middle part (9) consist of a single part made from one piece of textile fabric, such that there is no junction area between them.

(8) Furthermore, the rear panel (7) and the middle part (9) display an elasticity modulus in the upward direction and in the widthwise direction of 150 cN for stretching by 145% for a stretching stress of 15 cN, while the front part (3) and the two rear side parts (8a) and (8b) display an elasticity modulus in the upward direction and in the widthwise direction of 100 cN for stretching by 50% for a stretching stress of 15 cN.

(9) The boxer shorts (1) include a waistband (11) located on an upper part (12) of the pants portion (2), which waistband (11) is intended to be placed around the waist of a wearer, and which waistband (11) has a degree of expandability in the widthwise direction of 145% for a stretching stress of 15 cN.

(10) The waistband displays an elasticity modulus in the widthwise direction of 550 cN for stretching by 145% for a stretching stress of 15 cN.

(11) In a preferred embodiment, the rear panel (7) and the middle part (9) are made from a stretchable jersey knit fabric that has a weight of 170 g/m.sup.2 and that consists of 90% cotton and 10% elastane.

(12) In a preferred embodiment, the front part and the rear side parts are made from a single-knit jersey fabric that has a weight of 170 g/m.sup.2 and that consists of 95% cotton and 5% elastane.

(13) The boxer shorts according to the disclosure are manufactured in accordance with a cut-and-sew procedure. However, they may also be manufactured in accordance with a bonding procedure in which materials are bonded together rather than being sewn together. Last, these boxer shorts can be manufactured in accordance with a so-called “seamless” or Santoni procedure, in which a product is created in the form of a single integral piece by means of Santoni-type equipment. Thanks to this procedure, the expandability of the product can be varied depending on the various areas of the product.

(14) More specifically, FIG. 1 shows the rear part (6), as described hereinabove, of the boxer shorts according to the disclosure.

(15) More specifically, FIG. 2 shows the front part (3) and the middle part (9), as described hereinabove, of the boxer shorts according to the disclosure.

(16) FIG. 3 shows, on a diagram illustrating the elasticity modulus as a function of the stretch, the difference between the hysteresis curve for a waistband according to the disclosure (for example, as described with reference to FIG. 1 and FIG. 2) (curve 13) and a known waistband according to the prior art (curve 14), showing, for example, 80% expandability for a stretching stress of 15 cN and an elasticity modulus of 800 cN for 80% expandability for a stretching stress of 15 cN.

(17) A reading of these superimposed curves 13 and 14 reveals that the greater the expansion of the waistbands, the lower the elasticity modulus of the waistband according to the disclosure in comparison with the elasticity modulus of the waistband according to the prior art for the same expansion. It can also be seen that the waistband according to the disclosure can be stretched over a range which is broader than that of the waistband according to the prior art.

(18) Naturally, the disclosure is not limited to the embodiment described as an example hereinabove, but also includes all of the equivalent techniques and the variants of the means described herein, as well as the possible combinations thereof.
