DETAILED DESCRIPTION OF EMBODIMENTS

[0019] The detailed description below of example embodiments is made with reference to the attached drawings. The same reference numbers in different drawings identify the equal or similar elements. Furthermore, the drawings are not necessarily to scale. The detailed description below does not limit the invention. The protective scope of the present invention is defined by the attached claims.

[0020] In the description, the reference to an embodiment or the embodiment or some embodiments means that a particular feature, structure or element described with reference to an embodiment is comprised in at least one embodiment of the described object. The sentences in an embodiment or in the embodiment or in some embodiments in the description do not therefore necessarily refer to the same embodiment or embodiments. The particular features, structures or elements can be furthermore combined in any adequate way in one or more embodiments.

[0021] FIGS. 1-4 show a first embodiment of the device or accessory according to the invention, indicated as a whole with number 1. The device or accessory 1 comprises a shaped sheet of suitable thickness, made for example of synthetic, semi-synthetic or natural material. In some embodiments, the shaped sheet is made of cotton, or a mixture of cotton and synthetic fiber, for example nylon, or aromatic polyurethane polyether or other material. The shaped sheet has a thickness comprised between 5 m and 3000 m, for example between 10 m and 3000 m based upon the activity or sport for which the device is intended, to achieve optimal results. One of the two surfaces of the shaped sheet has a high coefficient of friction, set for example according to the use for which the device or accessory is intended.

[0022] The sheet 1 comprises a first surface 1A, partially shown in FIG. 1, and a second surface 1B shown in FIG. 2.

[0023] An adhesive, indicated with A in FIG. 1, is applied to the surface 1A. More in particular, the adhesive A may be a pressure adhesive, thus providing a self-adhesive sheet. The adhesive A is typically compatible with the skin, i.e. it is suitable to stay into contact with the skin for a long time. Typically, the adhesive A is an adhesive like that used for sticking plasters.

[0024] The sheet forming the device or accessory 1 has a shaped perimeter line indicated with P.

[0025] In practical embodiments, the sheet 1 has a shaped central portion 3. As it is clearly apparent from FIG. 3, once applied to the user's hand M in the way described below, the shaped central portion 3 substantially covers the whole palm of the hand M.

[0026] A plurality of appendices, indicated with 5, 7, 9, 11, 13, 15A, 15B, 17A, 17B in FIGS. 2, 3 and 4, extend from the central portion 3. The appendices may be different in shape and number from what indicated in the drawing. What is important is that the device or accessory has appendices allowing it being firmly fixed on the hand back, as it will be explained below. Preferably, at least one appendix is provided for each between-the-fingers space, i.e. between adjacent fingers. As it will be described below, in advantageous embodiments the device has appendices that are configured so as to extend over the palm surface of the wrist and that allow completely to cover the palm, in addition to appendices extending over the hand back for firm fixing.

[0027] In the illustrated embodiments, the sheet forming the accessory or device 1 comprises four appendices 5, 7, 9, 11, indicated below as between-the-fingers appendices, as they are intended to be inserted in the four spaces between the fingers. In particular, as shown in FIG. 3, the between-the-fingers appendix 5 is applied between little finger D1 and ring finger D2 of the hand M. The between-the-fingers appendix 7 is applied between ring finger D2 and middle finger D3. The between-the-fingers appendix 9 is applied between middle finger D3 and forefinger D4. The between-the-fingers appendix 11 is applied between forefinger D4 and thumb D5.

[0028] The adhesive sheet furthermore comprises a side appendix 13, to be applied to the hand side between thumb D5 and wrist PL. In advantageous embodiments, a pair of appendices 15A, 15B is provided, that are applied to the hand side between little finger D1 and wrist PL. Appendices 17A, 17B are also provided, that can be advantageously applied so as to surround partially the wrist PL or to reach the palm portion, or palm surface, of the wrist, i.e. the surface that is on the palm side, thus ensuring the palm is completely covered.

[0029] FIG. 4 shows the positions taken by the appendices 5-17B described above once the accessory or device 1 has been applied to the hand M. The appendices have a sufficient length so that they can extend at least partially over the back of the hand M until they overlap at least partially one another, as shown in the central area of the hand back DS in FIG. 4.

[0030] The partial overlapping between appendices, in particular between the between-the-fingers appendices 5, 7, 9, 11 and the side appendices 13, 15A, 15B, allows the device 1 to be more firmly attached to the hand. In an advantageous embodiment, the between-the-fingers appendices 5, 7, 9 extend up to the wrist, where they can be furthermore fixed by means of a strip of film equal to that of the accessory or device 1 or simply by means of a wrist band, often used in sports.

[0031] As it is readily apparent from FIGS. 3 and 4, where the device 1 is shown applied to the user's hand M, the central portion 3 of the sheet forming the device or accessory 1 covers the palm practically completely. Namely, the sheet has such an extension that, when the user holds a tool or equipment, for example a tennis racket, the perimeter edge P delimiting the central portion 3 is positioned in areas where there is no pressure contact with the tool or equipment. In this way, the self-adhesive sheet does not become detached from the hand palm, as this detachment is usually caused by the mechanical action exerted by the tool or equipment over the line between the perimeter edge of the device and the skin and by the sweating entering between the self-adhesive sheet and the skin.

[0032] The accessory or device is firmly fixed to the hand M by means of the appendices 5-17B, folded and fixed to the hand back and/or to the wrist, in areas where there is no contact with the tool or equipment, i.e. in areas where the sheet forming the device or accessory 1 is not subjected to the mechanical stress of the tool or equipment that would tend to detach the self-adhesive sheet P from the skin, starting from the perimeter edge.

[0033] Several tests performed for different sports, have proven that such a shaped sheet, i.e. a sheet that, after having been applied, has no edges on the hand palm, that is in the area subjected to friction during use, remains firmly fixed to the hand also for long periods of physical training, for example during a tennis match, notwithstanding the strong friction exerted by the tool or equipment, for example by the racket handle, on the whole palm. With the exception of particular hyperhidrosis cases, sweating is poor in the hand palm; therefore, a firm fixing is ensured by means of the adhesive A between the central portion 3 of the sheet forming the device or accessory 1 and the skin of the hand palm. The hand back, to which the side appendices 5-17B are fixed, is not subjected to the mechanical stresses caused by the grip on the tool or equipment, and therefore a firm fixing is ensured also in case of sweating.

[0034] The layer of adhesive A applied to the back surface of the self-adhesive sheet 1 is protected by means of a removable protective film. The protective film can be made of paper, cardboard, fabric or other material, even a synthetic material, that is suitably treated, for instance, but without limitation, with silicone, so that it can be easily peeled off from the layer of adhesive A.

[0035] To facilitate the application of the device or accessory 1 to the hand M, due to the complex shape and the wide surface thereof, in some embodiments the protective film, instead of being made of a single piece or of two portions, is subdivided into a number of portions greater than two, delimited by separation or cutting lines shown in particular in FIG. 1, that allow the user to apply the self-adhesive sheet to the hand one portion after the other where the protective film has been removed, without the risk that the various parts or appendices of the self-adhesive film stick to one another causing wrinkles that could not be flattened and would make the device unusable.

[0036] FIG. 1 illustrates, just by way of example, a possible subdivision of the protective film, that is indicated as a whole with PP and covers the adhesive A on the surface 1A of the sheet forming the device or accessory 1 before use. PP1, PP2, . . . PP15 respectively indicate fifteen segments or portions of protective film, each of which may be removed separately from, and independently of, one another.

[0037] In some embodiments, the accessory or device 1 is produced starting from a continuous or discontinuous composite web, formed by a base sheet, an adhesive layer A and a continuous protective film applied to protect the adhesive. By means of die cutting, laser cutting or the like, from the continuous web the single devices or accessories 1 are cut with their back protective film PP, that can be subdivided, at the same time or later, into single portions PP1-PP15 by means of laser cutting, die cutting or the like.

[0038] In this way, to apply the accessory or device 1 to the hand M the user removes a portion of the protective film and makes the adhesive surface portion below, no longer protected by the protective film, adhere to the skin; then he/she does the same with an adjacent portion, according to precise advantageous sequences, one of which is numerically indicated in FIG. 5. This kind of application allows to wear the accessory or device like a hand garment, that perfectly adapts without causing imperfections or wrinkles, that could not be avoided if the areas of adhesive film to be applied would be too wide.

[0039] Once applied, the accessory or device 1 allows the user a more effective and accurate grip on the tool or equipment or ball, wherein the grip is also completely dry, and thus allowing the maximum powerful athletic movement, ensuring great sensitivity and optimal skin protection. The adhesion of the accessory or device 1 lasts for a long time, also for the whole duration of a sport match, thanks to the particular shape described above, which avoids gradual detachment in the area where the hand presses firmly on the tool.

[0040] To improve the effectiveness of the device or accessory 1, the surface 1B into contact with the tool or equipment may be treated in a known manner to increase the friction coefficient thereof, or the base synthetic material of which the device is made may have a sufficient friction coefficient per se.

[0041] FIGS. 5 and 6 show a further embodiment of an accessory or device 1 according to the present invention. The same reference numbers indicate the same or equivalent parts to those described with reference to FIGS. 1 to 4. The accessory or device of FIGS. 5 and 6 is intended for the right hand. FIG. 5 shows the back surface that shall adhere to the hand, and illustrates an advantageous sequence for removing the protective film portions and for making adjacent areas of the adhesive sheet progressively adhere to the skin one after the other. FIG. 6 shows the front surface, with high friction coefficient, that remains exposed.

[0042] In this second embodiment again, the device or accessory 1 comprises a shaped sheet of suitable thickness made of a suitable material, for example a synthetic, natural or semi-synthetic material, wherein the sheet is shaped along a perimeter line P. The sheet 1 comprises a first surface 1A, partially shown in FIG. 5, and a second surface 1B, shown in FIG. 6. An adhesive A is applied to the surface 1A.

[0043] The sheet 1 has a shaped central portion 3 intended to cover substantially the whole palm of the user's hand. A plurality of appendices, indicated with 5, 7, 9, 11, 13, 15, 17A, 17B in FIG. 6, extend from the central portion 3. More in particular, in this embodiment, the sheet forming the accessory or device 1 comprises four appendices 5, 7, 9, 11, indicated below as between-the-fingers appendices, as they are destined to be inserted in the four spaces between the fingers. In particular, the between-the-fingers appendix 5 is applied between little finger and ring finger. The between-the-fingers appendix 7 is inserted between ring finger and middle finger. The between-the-fingers appendix 9 is inserted between middle finger and forefinger. The between-the-fingers appendix 11 is inserted between forefinger and thumb.

[0044] The adhesive sheet furthermore comprises a side appendix 13 to be applied to the hand side between thumb and wrist. In the embodiment illustrated in FIGS. 5 and 6, a long appendix 15 is furthermore provided, to be applied to the hand side between wrist and little finger up to the hand back and then around the wrist.

[0045] Similarly to the previous embodiment, further appendices 17A, 17B are provided, that can be applied so as to surround partially the wrist or to achieve the palm portion or palm surface of the wrist, i.e. the surface that is on the side of the hand palm, thus completely covering the hand palm surface. The length of the appendix 15 is sufficient to surround at least partially the wrist, overlapping the appendices 17A and 17B and thus keeping them fixed.

[0046] As in the embodiment described with reference to FIGS. 1-4, the central portion 3 of the sheet forming the device or accessory 1 covers the palm almost completely; in particular, the extension of the central portion is such that, when the user grips the tool or equipment, for example a tennis racket, a golf stick or other tool or equipment, the perimeter edge P delimiting the central portion 3 is positioned in areas where there is no pressure contact with said tool or equipment. In this way, the self-adhesive sheet does not become detached from the hand palm, as this detachment is usually caused by the mechanical action exerted by the tool or equipment over the line between the device perimeter edge and the skin and by the sweating entering between the self-adhesive sheet and the skin.

[0047] In this case again, the accessory or device is firmly fixed to the hand by means of the appendices 5-17B, folded and fixed to the hand back and/or to the wrist, in areas where there is no contact with the tool or equipment, i.e. in areas where the sheet forming the device or accessory 1 is not subjected to the mechanical stress of the tool or equipment that would tend to detach the self-adhesive sheet P from the skin, starting from the perimeter edge.

[0048] The layer of adhesive A applied to the back surface of the self-adhesive sheet 1 is protected by means of a removable film. To facilitate the application of the device or accessory 1 to the hand, due to the complex shape and the wide surface thereof, also in the embodiment of FIGS. 5 and 6 the protective film, instead of being made of a single piece or of two portions, is subdivided into a number of portions greater than two, delimited by separation or cutting lines, shown in particular in FIG. 5, that allow the user to apply the self-adhesive sheet to the hand one portion after the other according to preferred sequences, one of which is shown in FIG. 5 (the order corresponds to the reference number sequence), without the risk that the various parts or appendices of the self-adhesive film stick to one another before being completely applied to the hand. FIG. 1 illustrates, just by way of example, a possible subdivision of the protective film, that is indicated as a whole with PP and covers the adhesive A on the surface 1A of the sheet forming the device or accessory 1 before use. PP1, PP2, . . . PP22 respectively indicate twenty two segments or portions of protective film, which may be removed separately from, and independently of, one another. Namely, the user shall advantageously remove one portion of protective film at a time, make the adhesive portion below, no longer protected by the protective film, immediately adhere to the skin, and then do the same with the subsequent portion.

[0049] While the particular embodiments of the invention described above have been shown in the drawing and described integrally in the description above with features and characteristics relating to different example embodiments, those skilled in the art will understand the modifications, changes and omissions are possible without however departing from the innovative learning, the principles and the concepts described above and the advantages of the object described in the attached claims. Therefore, the scope of the described improvements shall be determined only based upon the widest interpretation of the attached claims, so as to include all the modifications, changes and omissions. The scope of the invention also includes any combination of the features claimed in one or more of the dependent claims and the features of any one of the independent claims.
