Description

PROTECTIVE STRUCTURE FOR ARTICULATIONS AND METHOD FOR

MAKING THE SAME

DESCRIPTION The present invention refers to a protective structure for articulations, in particular for use in dynamic sports.

As it is known, the protective clothing for dynamic sports provides protections to be used for shielding the body parts at higher risk of trauma in case of fall or impact against an obstacle.

Typically, besides the so-called 'back protection' in the sportsperson' s clothing there are provided protective accessories dedicated to the articulations, characteristically shaped as semirigid shells, made integral to the clothing item and apt to cover the anatomical zone at risk of serious injuries.

The art is aware of various types of protectors for articulations, typically made with more or less rigid materials, anyhow scarcely or even not flexible, being destined to absorb and to distribute the forces generated by a knock.

Known protectors always entail a drawback, in that the rigidity and the extension of the protector on the articulation result from a compromise between the sought level of protection, and therefore of safety, and the wearer's comfort. In fact, typically, the sportsperson upon wearing the clothing item incorporating this type of protections assumes a posture dictated by the latter rather than a natural one .

Hence, object of the present invention is to provide a protective structure for articulations overcoming said drawback by means of the particular arrangement of the protective constituent members thereof, making it particularly effective as a protection, and concomitantly particularly flexible and, hence, extremely comfortable to the wearer. Hence, the present invention provides a protective structure for articulations, in particular for use in dynamic sports, comprising a first protective member and a second protective member, each apt to protect the limb portion concerned in the articulation, characterized in that it further comprises elastic means for connecting said first member and said second member therebetween, said elastic means being also apt to protect the underlying articulation. Advantageously, the particular shape of the structure of the present invention allows to carry out excursions and rotations of the interested articulation in a wholly natural (anatomical) way, though not compromising the inherent safety thereof. Hereinafter, a detailed description of some preferred embodiments of the present invention will be provided, given by way of a non-limiting example, making reference to the attached drawings, wherein:

With reference to Fig. 1, a clothing item incorporating a plurality of protections is illustrated. The latter typically protect articulations of the upper and lower limbs, and each thereof is made of a protective structure 1 for articulations according to the present invention (better illustrated hereinafter) .

With reference now to Figs. 2A, 2B and 2C, the protective structure 1 for articulations of the present invention is illustrated. According to the present invention, the structure 1 has a first member 2 and a second member 3, each apt to protect the limb portion concerned in the articulation. The members 2 and 3 are mutually connected by a flexible structure 4 made of a plurality of laminated members 5, each thereof connected to the respective adjacent laminated member 5 by spacers 6 .

Each spacer 6 is integral to two adjacent laminated members 5. Moreover, the arrangement is such as to implement a structure having the spacers 6 staggered the one with respect to the other.

Moreover, the laminated members (segments) 5 are shaped, made of a material having high rigidity in a direction orthogonal to the articulation and high flexibility in a direction substantially tangential thereto.

The structure 4 thus obtained has optimum features of elasticity provided by the compliance of the assembly of laminated members 5, and, concomitantly, it effectively protects the articulation by virtue of the transversal thickness of the latter. Furthermore, by virtue of the shape of the structure 4, the latter is particularly flexible and apt to follow all the rotations of the underlying articulation, without compromising the protective function thereof. The shape and the dimensions of the end members 2 and 3 are unessential features of the invention, as the elasticity of the protection is provided to the latter by the specific shape of the structure 4, whereas for the end members merely the covering of the zones nearby the articulation is required. Hence, the former could also be absent , though the covering of a zone more extended than that concerned in the articulation is generally required.

With reference now to Figs. 3A, 3B and 3C, a second embodiment of the structure of the present invention is illustrated. For simplicity's sake, same components will have same numbers, and a further detailed description thereof will be omitted.

In case the protection is made of plastics material, the entire structure consisting of the end members 2 and 3, connected to the plurality of laminated segments 5 by the spacers 6, can advantageously be piece-formed. According to this embodiment, it is provided that the flexible structure 4 be made of the assembly of the laminated members 5, each thereof being connected to the respective adjacent one by a pair of spacers 6. The spacers 6 are located onto two lines parallel thereamong, however other locations are viable as well.

It has to be pointed out that the elasticity of the structure 4, as well as that of the assembly 1, is given by the flexural and torsional elasticity of the spacers 6, as it is depicted in Fig. 4. The two embodiments of structure as hereto illustrated can be held covering the articulation by suitable self-supporting means, or be inserted in the clothing item, into suitable pockets.

In the case of insertion into the clothing item, according to the present invention the protection can be provided integral to the same cloth of the clothing item, so as to simplify the manufacture of the protective clothing and to attain a higher reliability in the protective action. With reference now to Figs. 5A, 5B and 5C, a third embodiment of the structure of the present invention is illustrated. In this case as well, for simplicity's sake, same components will have same numbers, and a further detailed description thereof will be omitted. According to the present embodiment, the structure 1 is obtained from a mold in which the flexible structure 4 is honeycomb-shaped, and it is integrally obtained therefrom together with the protective members 2 and 3.

As it is apparent from Figs. 5A, 5B and 5C, according to the present embodiment, initially at opened mold and onto one of the two dies thereof, a support 9 made of cloth (or, e.g., of suitably treated leather or the like) is placed, thereby allowing the plastics material to adhere to the support during closed mold injection. After the injection of plastics material, the product of the molding will consist of the structure as shown in Fig. 5A, the cloth 9, or leather, etc. being made integral to the outer side thereof.

Subsequently, e.g. when packaging the clothing item, the structure 1 thus made is axially compressed in order to generate transversal bends 8 as depicted in Figs. 5B and 5C. Then, the structure is secured at two sidelines, e.g., by respective seams or bondings 10 and 11. Characteristically, the product thus obtained will allow the relative rotation of the two ends 2 and 3, as depicted in Fig. 6 and be easily incorporated in the clothing item with simple seams.

With reference now to Figs. 7A, 7B and 7C, a fourth embodiment of the protective structure of the present invention is illustrated. For simplicity's sake, same components will have same numbers, and a further detailed description thereof will be omitted.

The present fourth embodiment of the structure 1 is simplified with respect to the preceding embodiment.

In this case, it is provided that the mold have no member for connecting the laminated members thereamong, as it is the cloth (or the leather) that, upon being made integral thereto, serves as member for connecting the laminated segments 5 and the end members 2 and 3 thereamong.

For the making of the structure 1 according to said embodiment, the process as hereto illustrated is carried out.

With reference to Fig. 8A, the structure of Figs. 7A, 7B e 7C is illustrated, in a bent condition.

This versatility meets all the needs dictated by the type of sport practice and the type of clothing item at issue, anyhow making the protective structure 1 an integral component of the sportswear incorporating such protections .

In particular, in certain sports there can be a demand for protections made of materials especially resisting to repeated impacts and arranged on the outside of the clothing item in order not to damage the supporting cloth in a fall. More precisely, and with reference to Fig. 8B, according to the present invention there can be provided that at the manufacturing stage the suppporting cloth (or leather) 9 be placed onto the mold die facing the inside of the protection 1, so that the latter be applied on the outside of the assembled clothing item. Thus, the resisting structure is located externally to the item and, upon impacting, also protects the cloth (or leather) . Moreover, the structure 1 as illustrated in the preceding embodiments is apt to protect any sportsperson' s articulation, both of the lower and of the upper limbs. E.g., though it is not shown in the Figs., the structure 1 thus made is also suitable for tinier articulations, like the finger ones.

Of course, the above description of the present embodiment applying the innovative principles of the present invention is susceptible of ameliorative variants encompassed by the scope of the appended claims.
