[0002] The proposal is used in particular in the field of the manufacture of safety elements for trousers and sports trousers or cyclists' trousers and for garments thus finished which must be applied on the inside thereof, without therefore excluding alternative applications and consequently 10 in any type of technical item of clothing where it is necessary to protect the groin zone and the peripheral groin zone of the body against contact with such safety elements.

In the usual practice of cycling, be it from the cycling amateur or from the professional cyclist, fairly often reds or skin irritations result that predominantly arise in the groin zone and peripheral groin zone of the body, since these parts, despite the technical garment, whether it is a pair of trousers or cyclists' trousers, the pedal steps are supported and irritated during support on the rigid surface of the saddle. From a practical point of view, the pedal steps have the error of transmitting the defects of the terrain, because the parts of the body concerned are repetitively and indirectly loaded. In addition, the temperatures established in the groin zone and in the peripheral groin zone are usually higher than the conventional ones, with such a phenomenon essentially promoting exudation and, consequently, more frequent redness and irritation, often with significant skin lesions due to a skin lesion. 25 stronger friction due to contact with direct friction between the skin and the technical item of clothing.

The requirement thus arose to find a padding with a generally protective function which is used between the skin of the groin zone and the peripheral groin zone and the technical garment consisting of cyclists' pants or trousers. This padding, which is usually provided with a special and layered composition of rounded material and which extends from the pubic zone to the coccyx zone and which has a curvature, is usually identified by the name inlay and becomes stronger in relation to the inside of the garment, in that it is connected to the fabric that connects the garment correspondingly to the crotch region. Originally, deer leather 10 was commonly used among the most popular materials, which was preventively assembled with plastics or open-cell thermoplastic and provided with a special curved geometry, and then sewn together precisely to the intersection. After years of evolution of the materials and of the requirement to improve the production costs by improving user comfort, it came to various solutions.

State of the art

U.S. Pat. No. 5,271,111 (Speth et al.) Proposes an insert for cyclists' trousers which must be adapted to the anatomical figure of the cyclist. As with the previous types, the well-known cyclists' trousers are provided with padding to stop shocks and vibrations transmitted by the bicycle saddle. The cyclists' trousers are also designed to remove moisture from the body and to allow freedom of movement and to limit friction and its effects to an acceptable level.

The cyclists' trousers, Ultimate Short products from Bike Nashbar 25 of Youngstown, Ohio, have an inlay with layers of Ultrasuede ™, expanded polyurethane and an outer layer of polyurethane. Ultrasuede ™ is a synthetic mottled material that is manufactured at Wilmington's Du Pont in Delaware. Other cyclists' trousers manufactured by Nashbar have a double-layered chamois leather and enclose layers of expanded polyurethane, sponge fabric or raw wool fabric. U.S. Patent No. 4,961,223 (Black) proposes a tanned thermoformed laminated leathers from Ultrasuede ™ and a crude wool of polyester mesh assembled with an adhesive.

The cyclists' trousers thus obtained have the advantage that they can be manufactured simply and inexpensively. In addition, they provide correct anatomical adjustment for better comfort for the cyclist.

[0007] The cyclists 'trousers enclose a body part and a pair of trousers that are connected to the inner surface of the body part of the cyclists' trousers. The occupation includes a seat cushion and numerous pressed-in marking lines that are specially positioned so that the occupation adapts to the anatomical profile of the cyclist in the riding position on a bicycle saddle. The body part of the cyclists pants has an opening for the belt and two openings for the legs that allow the person 10 to insert one leg each through each opening and to pull on the cyclists pants in position of use. The trouser covers the seats and the pelvic area and extends upwards into the frontal lower pelvis area of the person who has put on the cyclists pants. The occupation is connected to the inner surface of the body part with the cycling shorts via a seam or through a layer of the occupation. The numerous pressed marking lines on the occupation include in principle longitudinally arranged marking lines which extend through the coverage area of the pelvic area, so that the folds of the occupation are along the length marking lines and there the legs of the person carrying the garment there better are being adjusted. Moreover, the occupation has generally curved cross-marking lines which are arranged in the coverage area of the lower pelvis zone, so that the occupation folds along these marking lines and, more effectively, envelops the person's lower pelvis zone from the front part to the rear part.

The occupation of the cycling shorts consists of an inlay formed by thermoforming, which comprises the following: - a back layer with an inner surface and an outer surface, said back layer generally being formed around the seating surfaces, the pelvic area and the lower cover a cyclist's pelvic cavity; a padding with foam layer corresponding to the shape of said backing layer 30 and fixed to the inner surface of the backing layer; a protective layer which is laid over said foam cushion and which is sewn together with a peripheral edge of said backing layer, said protective layer facing the body of the cyclist; - numerous marking lines which are perfectly accentuated in said layer and which are arranged through said layer of the occupation, the 5 accentuated lines forming numerous furrows in the layer which are so stretched that said curves of the occupation are anatomically attached to the body along this furthest front adjust the cyclist's cycles, while reducing the cyclist's friction in a riding position; - the backing layer comprises a piece of nylon material sewn onto the cycling shorts.

The padding is an expanded open-cell polyurethane material. The surface layer is a polyester / nylon blend.

Patent EP 0 643 929 (Tanaka) proposes a garment for the protection of the hip joint and the crotch region, in particular for cycling, motorcycle racing and riding out. It consists of a main body with parts for the legs, each of the leg parts being closed off by a profile which, during use, is located below the hip joint region of the wearer; and from a safety pad which, during use of the person's crotch region, extends to at least one zone below the hip joint toward the edges of the leg portions. The safety padding comprises a padding that includes a fleece or a flexible, open-cell, expanded polyurethane material, and a padding for said padding that comprises a knit or fabric. In this case, the safety padding on the inside of the main body or on the garment is sewn on and comprises a non-woven fabric with an apparent specific weight of 0.05-0.09 g / cm 3, or consists of a flexible, open-cell, expanded polyurethane material with an apparent specific weight of 0.02-0.09 g / cm3. One of the expectations is that the padding underlay can also comprise a non-woven fabric or a flexible, open-cell, expanded polyurethane material with at least the first laminated side, with a mesh or a fabric, and where the padding is formed without a sewn part and not on the surface appears. The padding is connected to the occupation by thermal bonding and is printed three-dimensionally to be adapted to the shape of the groin area and the peripheral groin area of the person's body.

Patent EP 1 269 873 (Maier) describes cycling shorts with a safety inlay for the body parts that sit on the bicycle saddle. In order to achieve a perfect adaptation of the innovative insert to the cyclist's movements and to eliminate all skin-contacting frictions, it is composed of an insert layer of expanded material, over which an elastic fabric in all directions directly onto the body contacting side of the user. The inlay layer is made from expanded rubber, the fabric preferably being achieved using elastomer fibers that have a tensile capacity of more than 5%.

Patent IT2000U000035 (Coccia) proposes a structure of safety elements especially for bicycle pants that are analogous to those of the previous type. The structure of the security element consists of a support made of bi-elastic material or of allowing it to be extended, taking into account its extension, according to further orthogonal planes. The support has an elasticity of 30 to 40% and can consist of a fabric of, for example, lycra with microfibers. An open-cell bi-elastic padding and high density are held together on the support. The bi-elastic padding has a density of between 55 kg / m and 95 kg / m. It preferably has a density of as much as 65 kg / m. The thickness is between 5 mm and 12 mm, with a preferred use of 10 mm. The bi-elastic padding is only used in accordance with the saddle support points. The bi-elastic padding is composed of a first middle element that fits exactly to the correct curve of the bicycle seat. On the transverse ends of the middle section, a second section and, afterwards, a pair of third sections have been placed below the intermediate layer of smooth surfaces. The third pieces are symmetrical to an elongated middle plane on the bi-elastic padding and are subdivided per se from a second smooth zone located on the middle longitudinal plane. The bi-elastic padding and the respective support are composed by means of a high-frequency or thermoforming or ultrasonic technique.

The rubbery polymerizates are known and are products obtained over an anionic polymerization and can be formulated with cans of halides or silicon halides to improve the characteristics of the rubber for use in certain applications. An application example of the said material is identified in GB 2 411816 (Speedo), in which a technical item of clothing is described, in particular a swimsuit, the fabric lane of which is locally covered with a series of protuberances made of rubbery polymer in accordance with the forearm.

State of the art of the invention

The patent ITMI2007A000557 (Sparco) relating to a glove is not a public patent application, however, it must be withheld that the patent application relating to a glove to improve the comfort and grip where the outer surface of the glove support material corresponds to the palm of the hand, is locally provided with a zone of protuberances, consisting of conical or cylindrical volcanic microcapsules which are made of non-rigid thermoplastic or elastomeric material or of both materials, with an almost concave, also provided with hole-lowering on the highest point.

According to the above statements, the following must be taken into account: a) an investment; b) a technical item of clothing, trousers or cycling shorts that is provided with an inlay that fits precisely on the inner surface of the pelvic zone covering the seating surfaces and runs upwards into the frontal lower pelvic zone of the trousers or cycling shorts; c) the insert is formed essentially from the following: - a back layer with an inner surface and an outer surface, wherein the back layer is generally shaped so as to cover the seat surfaces, a pelvic zone and the lower pelvic cavity of a cyclist; - a padding with a plastic coating of expanded polyurethane corresponding to the shape of said backing layer sewn onto the inner surface of the backing layer; - a cover layer which lies on said foam cushion and is applied on a peripheral edge of the back layer, said occupancy layer being placed opposite the body of the cyclist; 7 - fitting exactly over the top layer or over it there are numerous reliefs formed on the circumference that differ from the seating area of the front part of the insert, which mutually form numerous channels in the top layer, d) a technical item of clothing provided with a zone of protuberances in the form of conical or cylindrical microcapsules that were obtained from a non-rigid thermoplastic or elastomeric material or from both materials, with a hole-lowering at the highest point.

Disadvantages [0015] The previously described solutions have according to the

Applicant some drawbacks. In particular, the described solutions do not seem to optimally meet the requirements of the gentle cyclist who demand maximum comfort, in particular under special skin stresses. The constant contact of the body, even when limited on certain protruding parts of the insert due to the uniform, substantially smooth surfaces, reduces the possibility of the skin being properly ventilated to promote exudation. Also, during pedal tread, due to the contact of the skin with the formed elevations with uniform planes, friction necessarily results with the likely possibility of increasing the skin load.

[0016] On the basis of the foregoing, the requirement of the companies in the sector must be taken into account to individualize the innovative solutions and, at least taking into account the problems just described above, to minimize them.

Summary of the invention

These and further objects are achieved by the present invention according to the features detailed in the enclosed claims, in that the aforementioned problems are solved by means of an insert and trousers or cycling shorts with an insert, a high ventilation surface with a low coefficient of friction 30 and in the following manner with: - a back layer with an inner surface and an outer surface, wherein the back layer is generally shaped so as to cover the seat surfaces, the pelvic zone and the lower pelvic cavity zone of the cyclist; - a padding with an expanded polyurethane layer that corresponds to the shape of the backing layer and is applied on the one hand to the inner surface of the backing layer and on the other hand to a possible occupation or support layer; - at least one protruding layer formed in that it forms at least the back layer or is placed thereon and sewn together with the back layer, said protruding layer lying on the body of the cyclist and sticking to the sitting zone of the peripheral front part , the side part and the rear part of the insert are distinguished in that they mutually form numerous channels in the cover layer; Wherein, corresponding to the protruding layer or protruding layer and at least a portion of the backing layer, or protruding layer corresponding to the coupling connection of the backing layer, protruding conical or cylindrical microcapsules are present in volcanic form made of non-rigid thermoplastic or made of elastomeric material or also of both materials, with a reduction at the highest point also provided with a hole 15.

Goals

Thanks to the considerable creative contribution, the operation of which involves an immediate and not negligible technical progress, several remarkable objectives are achieved.

A first goal was to obtain an insert that should offer the cyclist greater comfort. This leads back to soft and elastic microcapsules, which regain their shape, which, if necessary, make it easier to adjust the surfaces of the insert to the multiple and subjective anatomical qualities of the respective body, which connect more directly than indirectly. If we look at the material density, distribution, quantity and size of the microcapsules, it is moreover possible to freely vary the design of the connection faces of the insert because zones are obtained that are locally more or less rigid compared to others which also connect to each other. Therefore, at the place where the skin has a smaller thickness, with greater flexibility of the bearing surface compared to other interventions, one can intervene better, while the greater thickness allows a better shock and vibration damping during pedal treads.

A second objective achieved is to facilitate ventilation and to reduce the friction of the skin with the insert. The materials currently used for the manufacture of inserts, however, allow better exudation to be achieved, since they can of course be exchanged where the body parts fit almost uniformly to locally smooth surfaces. The use of the microcapsules allows to achieve a substantial reduction of the loaded zone of the insert with respect to the cyclist's skin on the corresponding total surface area, promoting a slight separation with respect to the surface and between the same microcapsules, gaps 10 through which an air stream circulates. This phenomenon reduces exudation and to be considerably more comfortable, it greatly reduces the skin load.

Finally, these and further advantages have the non-negligible characteristic of determining an insert and a pair of trousers or cycling shorts with an insert provided with good technological content.

These and further advantages are cited in the following detailed description of certain preferred solutions of embodiments with the aid of the enclosed schematic drawings, in which the details of the embodiments are not to be considered as limiting but solely as examples.

Practical embodiment of the invention

The present invention relates to an insert 10a, 10b, 10c and 10d and to pants or a cyclist's pants (not shown) with the said insert 10a, 10b, 10c and 10d. To be precise, in the top view each insert 10a, 10b, 10c and 10d with a rear part 101 with a broad surface with a semi-circular circumferential profile can be seen which, by means of a central composite part 102 corresponding to a curvature, has a front part 103 is sewn together with a semicircular profile with a smaller diameter opposite the rear part 101.

Each inlay 10a, 10b, 10c and 10d has, according to the side opposite the body of the cyclist, a backing layer 100 with an inner surface 101 and a molded outer surface 102, the backing layer 100 being generally shaped so as to cover the cyclists' pelvis areas, the pelvic zones and the lower pelvic zone.

The backing layer 100 is arranged with the inner surface 101 on a padding 110 which is provided with a layer of, for example, polyurethane foam which corresponds to the shape of the backing layer 100 and the padding 100 with the lower connection of a possible, superficial and not -displayed bearing layer is composed.

Protruding layers 121, 122 and 123 are provided on the outer surface 102 of the backing layer 100 of the inlay 10a, 10b, 10c and 10d, which layers have been applied to a bearing layer 120 which is placed on the outer surface 102 of the backing layer 100. In an alternative solution, the protruding layers 121, 122 and 123 are achieved directly on the outer surface 102 of the backing layer 100 of the insert 10a, 10b, 10c and 10d without an intermediate layer of the support layer 120. Two protruding layers 121 30 and 122, which can be seen in the plan view, are almost drop-shaped and are made correspondingly to the rear part 101 of the insert 10a, 10b, 10c and 10d, one being laterally and symmetrically opposite the other with the highest point facing the front part 103 of the 11 insert 10a, 10b, 10c and 10d. The protruding layer 121, 122 are separated from each other to leave an elongated and linear channel 130 between them which coincides with the longitudinal axis of the insert 10a, 10b, 10c and 10d. In this way, each protruding layer 121 and 122 in the rear part 101 faces two respective different support zones of the seating surfaces, i.e. the right and left zone. The third protruding layer 123 is provided in front of the two first layers 121 or 122, with the original middle part 102 of the insert 10a, 10b, 10c and 10d, to run to the front part 103 of the insert 10a, 10b, 10c and 10d . The protruding layer 123 is present in a horseshoe-shaped design, the middle part being a linear channel 131 which is connected to the insert and aligned in line with the linear longitudinal channel 13. The three protruding layers 121, 122 and 123 are assembled lying on the support layer 120 which, for their part, can yield elevations 124 in the respective covering areas of the protruding layers 121, 122 and 123 which circumferentially protrude from the protruding layers 121, 122 and 123.

In the solution of Figure 1, the insert 10a has protuberances consisting of perpendicular, conical or cylindrical, volcanic microcapsules 140 made of a non-rigid thermoplastic or elastomeric material or of both materials, with a concave, also of reduction at the highest point provided for by a hole 141. Said microcapsules 140 are evenly distributed, corresponding to the total surface area 20, which faces the body of the cyclist, the support layer 120 and the projecting layers 121, 122, 123 and 124.

In the solution of Figure 2, the insert 10b has the same protuberances as those of the previous figure, consisting of conical or cylindrical microcapsules 140 corresponding to the coupling connection 125 of the support layer 120 of the protruding layers 121, 122, 123 opposite the backing layer 100 are formed.

In the solution of Figure 3, the insert 10c has protuberances consisting of conical or cylindrical microcapsules 140 that are placed locally corresponding to the joining of the backing layer 100 opposite the support layer 120.

Finally, in the solution of Figure 4, the protuberances consisting of conical or cylindrical microcapsules 140 on the total surface 12 opposite the body of the cyclist, the insert 10d, were obtained.

The inserts 10a, 10b, 10c and 10d are provided on trousers or a cyclist's trousers (not shown). To be precise, the pants or cycling shorts provide the inserts 10a, 10b, 10c and 10d for those corresponding to the inner surface of the pants or cycling shorts, which correspond to the crotch region, and which cover the seat surfaces and the region of the pelvic zone and upwards walks into the frontal lower pelvis zone of the person wearing the trousers or cycling shorts.
