Description

FIELD OF TECHNOLOGY

The present invention relates to a device or device for facilitating and improving the capture of various types of equipment, including but not limited to sports equipment such as tennis rackets, golf clubs, baseball bats and the like, or for improving ball grip in such sports like basketball, rugby, American football, etc., which at the same time protects the skin of the hands during these classes. Embodiments of the invention described herein relate to a disposable device or device.

BACKGROUND

Many sports require a tight inventory capture. Proper grip is a prerequisite for the implementation of inventory management and, therefore, is important, for example, in professional sports. As a rule, the correct racket grip is essential for maximum control of the ball. The same applies to other sports, such as golf, where the correct grip of the club affects the path of the ball, or other sports where optimal grip of the ball contributes to the accuracy of the throw.

Currently, this is achieved by coating the surfaces of the captured equipment or the ball thrown with special films, and these surfaces are always in contact with human skin. However, this contact is not optimal, since human skin is not predisposed to perform this function. Especially in the case of sweating, which usually occurs during sports, the seizure becomes unreliable and less dense, which increases the risk of skin injuries.

Some sports use gloves; however, due to their thickness and movement relative to the skin of the hand, they reduce sensitivity and are therefore unsuitable for use in many sports or activities.

A good example of the current need for grip enhancement systems is tennis, in which some players, especially professional athletes, attach a patch to their fingers to improve grip and protect the skin. However, these attempts lead to an unsatisfactory result, the main reason for which is that they use only a small surface of the fingers, and not the entire palm. In fact, patches or adhesive tapes applied to partially cover the palm of the hand tend to quickly detach from the skin due to mechanical interaction between the handle of the racket or other equipment and the edge of the perimeter of the patch or tape and the skin, as well as due to perspiration occurring between the patch and the skin.

Thus, it is required to create a device or device that allows to eliminate or reduce the above disadvantages.

SUMMARY OF THE INVENTION

The invention discloses a device for facilitating the capture of equipment or a tool, or a sports ball, which includes a sheet of shaped material, for example, synthetic, semi-synthetic or natural material, containing a first surface on which a pressure sensitive adhesive suitable for adhesion to the skin is applied, and a second surface located opposite the first surface and preferably having a high coefficient of friction. The device or device comprises a central part having a shape and size close to the shape and size of the palm and a plurality of additional elements extending from the edge of the perimeter of the central part and adapted to adhere to the back of the brush by means of said adhesive. The adhesive is protected by a protective film; since the film is divided into many segments or sections, this makes it easy to apply the device or device to the brush, perfectly fitting it to the complex shape of the human hand. Namely, for applying the device, each segment or portion of the protective film is removed separately, and the uncovered portion of the adhesive film located beneath it is immediately pressed and attached to the skin before proceeding to the adjacent segment or portion. Segments or sections are removed in accordance with a preferred sequence for the gradual and sequential bonding of the adhesive sheet. Thus, when applying the device or device to the hand, it is possible to avoid the formation of wrinkles or irregularities on it that cannot be smoothed out and which make the device unusable, despite the complex shape of the device or device and the large adhesive force of the adhesive.

The device or device in accordance with the invention may be a disposable device or device; it is anatomically adapted to the human hand in such a way that it completely continuously closes the palm of the hand, thus fulfilling, on the one hand, the function of a glove, but excluding slipping on the skin, which is typical for a glove; on the other hand, the proposed device or device also serves as a skin, i.e. performs the same function as the skin in the area of contact with sports or work equipment, and, therefore, can be used instead. In essence, the device is configured to facilitate and improve the capture of various types of equipment, performing the function of a "second skin", specially designed and covering the entire friction area.

The size and shape of the central part is preferably such that the central part, after being applied to the wrist, extends from the base of the fingers to the palmar region of the wrist and from one side to the other side of the hand. Thus, the entire palm is completely closed and protected, and the edge bounding the sheet forming the adhesive device is located outside the contact and grip area between the hand and the tool or tool, thereby preventing the detachment that usually occurs along the edge of the adhesive film applied to skin due to movement of inventory or a tool held by a hand.

The idea underlying the invention is to transfer the grip from the tool, equipment or sports ball directly to the human hand using a device that is anatomically adapted to the shape of the hand and completely covers the palm, i.e. a grip area that adheres to the palm of your hand as a "second skin", thereby optimizing grip and delivering maximum power to your inventory, instrument or sports ball, and providing maximum sensitivity, thus guaranteeing the best possible result while protecting your skin.

Obviously, devices for the right hand and for the left hand can be made, as well as devices of different sizes in order to fit different sizes of hands:

Additional characteristics and embodiments of the proposed device are described below with reference to examples of an embodiment of the invention and in the attached claims, which is an integral part of the present description.

DETAILED DESCRIPTION OF THE INVENTION

The following is a detailed description of exemplary embodiments of the invention with reference to the accompanying drawings. The same or similar elements in different drawings have the same reference position. In addition, the drawings are not necessarily presented to scale. The following detailed description does not limit the invention. The scope of the claims of the present invention is defined by the attached claims.

In this description, a reference to “one embodiment” or “this embodiment”, or “certain embodiments” means that a particular feature, structure or element described with respect to any embodiment of the invention is included in at least one an embodiment of the present invention. The phrases “in one embodiment” or “in this embodiment,” or “in some embodiments,” as used herein, do not necessarily refer to the same embodiment or embodiments. Moreover, specific elements, structures or characteristics may be combined in any suitable manner in w one or more embodiments of the invention.

In FIG. 1-4, a first embodiment of the proposed device or device is shown, generally indicated by the number 1. The device or device 1 comprises a shaped sheet of suitable thickness made, for example, of synthetic, semi-synthetic or natural material. In some embodiments of the invention, the shaped sheet is made of cotton or a mixture of cotton and synthetic fiber, for example, nylon, aromatic polyurethane polyester or other material. The thickness of the shaped sheet is from 5 microns to 3000 microns, for example from 10 microns to 3000 microns, depending on the type of activity or sport for which the device is intended, in order to obtain optimal results. One of the two surfaces of the shaped sheet has a high coefficient of friction, established, for example, in accordance with the application for which the device or device is intended.

Sheet 1 comprises a first surface 1A partially shown in FIG. 1 and the second surface 1B shown in FIG. 2.

An adhesive is applied to surface 1A, indicated by the letter A in FIG. 1. In particular, adhesive A may be a pressure sensitive adhesive, thereby forming a self-adhesive sheet. Adhesive A is usually compatible with the skin, i.e. Suitable to be in contact with the skin for a long time. Generally, adhesive A is an adhesive similar to that used for adhesive plasters.

The sheet forming the device or device 1 has a perimeter line forming a complex shape, indicated by the letter R.

In practical embodiments, the sheet 1 comprises a shaped central portion 3. As can be clearly seen from FIG. 3, after applying to the user’s brush M in the manner described below, the shaped central part 3 essentially covers the entire palm of the brush M.

Many additional elements, designated 5, 7, 9, 11, 13, 15A, 15B, 17A, 17B in FIG. 2, 3 and 4. Additional elements may take the form and quantity different from what is shown in the drawing. It is important that the device or device contains additional elements that enable tight fixation on the back of the hand, as described below. In a preferred embodiment of the invention, at least one additional element is provided for each interdigital space, i.e. between adjacent fingers. As described below, in preferred embodiments of the present invention, the device comprises additional elements configured to extend through the palm surface of the wrist, which allows you to completely close the palm, in addition to the additional elements passing through the back of the hand to ensure a tight fit.

In the presented embodiments of the invention, the sheet forming the fixture or device 1 contains four additional elements 5, 7, 9, 11, indicated below as "interdigital additional elements", since they are designed to be placed in four spaces between the fingers. In particular, as shown in FIG. 3, the interdigital extra element 5 is applied between the little finger D1 and the ring finger D2 of the brush M. The interdigital extra element 7 is located between the ring finger D2 and the middle finger D3. The interdigital extra element 9 is applied between the middle finger D3 and the index finger D4. The interdigital extra element 11 is applied between the index finger D4 and thumb D5.

In addition, the adhesive sheet contains a lateral additional element 13 applied to the side surface of the hand between the thumb D5 and the wrist PL. In preferred embodiments, a pair of additional elements 15A, 15B are provided that are applied to the side surface of the hand between the little finger D1 and the wrist PL. In addition, additional elements 17A, 17B are made, which can be preferably applied in such a way as to partially surround the wrist PL or extend to the palmar part or the palmar surface of the wrist, i.e. surface located on the palm side, thereby providing full coverage of the palm.

In FIG. 4 shows the location of the above-described additional elements 5-17B after applying the device or device 1 to the hand M of the hand. The additional elements have a length sufficient to allow them to pass at least partially through the back side of the brush M until at least partially overlapping each other, as shown in the central part of the back side DS of the brush in FIG. four.

Partial overlapping of additional elements, in particular interdigital additional elements 5, 7, 9, 11 and side additional elements 13, 15A, 15B, allows for more tight attachment of the device 1 to the hand. In a preferred embodiment of the invention, the interdigital extra elements 5, 7, 9 extend to the wrist, where they can be additionally fixed with the film element from which the fixture or device 1 is made, or simply with the wrist bandage, which is often used in various forms sports.

As can be seen from FIG. 3 and 4, in which the device 1 is shown applied to the hand M of the user's hand, the central part 3 of the sheet forming the device or device 1 almost completely covers the palm. Namely, the sheet has such a shape and size that when the user holds the tool or equipment, for example, a tennis racket, the perimeter edge P bounding the central part 3 is located in areas in which there is no pressure contact with the tool or equipment. Thus, the self-adhesive sheet does not detach from the palm of the hand, which is usually caused by mechanical action from the side of the tool or equipment along the line between the perimeter of the device and the skin, as well as perspiration between the self-adhesive sheet and the skin.

The fixture or device is tightly fixed to the hands of M hands by means of additional elements 5-17B, bent and attached to the back of the hand and / or wrist, in areas where there is no contact with the tool or equipment, i.e. in areas in which the sheet forming the device or device 1 is not subject to mechanical compression from the side of the tool or equipment, which would lead to the detachment of the self-adhesive sheet P from the skin, starting from the edge of the perimeter.

Several tests conducted for various sports have proved that such a shaped sheet, i.e. a sheet that, after application, has no edges on the palm of the hand, that is, in the area subject to friction during use, remains firmly attached to the hand for long periods of time of physical activity, for example, during a tennis match, despite strong friction between the tool or inventory, such as a racket handle, and the whole palm. With the exception of special cases of hyperhidrosis, sweating in the palm of the hand is small; therefore, adhesive A provides tight fixation between the central part 3 of the sheet forming the device or device 1 and the skin of the palm. The back side of the brush, to which additional elements 5-17B are attached, is not subject to mechanical compression caused by the seizure of the tool or equipment, and, therefore, tight fixation is also provided in case of perspiration.

The adhesive layer A deposited on the back of the self-adhesive sheet 1 is protected by a removable protective film. The protective film may be made of paper, cardboard, fabric or other material, even synthetic material, treated accordingly, for example, without limitation, with silicone, so that it can easily be removed from the adhesive layer A.

To facilitate the application of the device or device 1 on the hand M of the hand, due to its complex shape and wide surface, in some embodiments of the invention, the protective film, instead of being made of one or two elements, is divided into more than two sections limited by separation lines or tearing, shown in particular in FIG. 1, which allows the user to apply the self-adhesive sheet to the hand, section after section, from which the protective film has already been removed, without the risk of adhesion of various parts or additional elements of the adhesive film to each other with the formation of wrinkles that cannot be smoothed out, which would render the device unusable.

In FIG. 1 illustrates, by way of example, a possible separation of the protective film, which is designated entirely by PP and covers the adhesive A on the surface 1A of the sheet forming the device or device 1 before use. PP1, PP2, ... PP15 respectively designate fifteen segments or sections of the protective film, each of which can be removed separately and independently from each other.

In some embodiments, a fixture or device 1 is fabricated starting with a continuous or intermittent composite web formed by a base sheet, adhesive layer A and a continuous protective film applied to protect the adhesive. By means of die cutting, laser cutting, and the like, individual devices or devices 1 are cut from a continuous web, the protective film of which can be divided at the same time or later into separate sections of the PP1-PP15 by laser cutting, die cutting, etc. P.

Thus, to apply the device or device 1 to the hand M of the hand, the user removes a portion of the protective film and sticks the portion of the adhesive surface located below it, which is no longer covered by the protective film, to the skin; then does the same with the adjacent section in accordance with the exact preferred sequences, one of which is indicated by the numbers in FIG. 5. This type of application allows you to wear the device or device as a "protective hand garment", which fits perfectly without the formation of bumps or wrinkles that could not be avoided if the areas of adhesive film to be attached were too wide.

Being applied to the hand, the fixture or device 1 provides the user with a more effective and accurate grip on a tool, equipment or ball, which is also completely dry, and thus allows for the most powerful athletic movement, providing high sensitivity and optimal skin protection. The adhesion of the device or device 1 continues for a long time, for example, throughout the entire sports match, thanks to the special shape described above, which avoids the gradual disconnection in the area where the hand tightly compresses the equipment.

To increase the efficiency of the device or device 1, the surface 1B in contact with the tool or equipment can be processed in a known manner to increase its friction coefficient, or the main synthetic material from which the device is made may have a friction coefficient sufficient in itself.

In FIG. 5 and 6 show an additional embodiment of the device or device 1 in accordance with the present invention. Parts similar to those described with reference to FIG. 1-4 have the same reference position. The fixture or device of FIG. 5 and 6, designed for the right hand. In FIG. Figure 5 shows the back side that should adhere to the hand, and shows the preferred sequence of removing portions of the protective film to ensure consistent adhesion of adjacent sections of the adhesive sheet one after the other with the skin. In FIG. 6 shows a front side having a high coefficient of friction that remains open.

In this second embodiment of the invention, the device or device 1 also comprises a shaped sheet of appropriate thickness made of suitable material, for example, synthetic, natural or semi-synthetic material, the sheet having a complex shape along the perimeter line P. Sheet 1 comprises a first surface 1A partially shown in FIG. 5 and the second surface 1B shown in FIG. 6. Adhesive A is applied to surface 1A.

Sheet 1 comprises a molded central portion 3 for closing substantially the entire palm of a user's hand. From the central part 3, there are many additional elements designated 5, 7, 9, 11, 13, 15, 17A, 17B in FIG. 6. More specifically, in this embodiment of the invention, the sheet forming the fixture or device 1 contains four additional elements 5, 7, 9, 11, indicated below as “interdigital additional elements”, as they are designed to be placed in four spaces between the fingers . In particular, the interdigital extra element 5 is applied between the little finger and the ring finger. The interdigital additional element 7 is applied between the ring finger and the middle finger. The interdigital additional element 9 is applied between the middle finger and the index finger. The interdigital extra element 11 is applied between the index finger and thumb.

In addition, the adhesive sheet contains a lateral additional element 13, applied to the side surface of the hand between the thumb and wrist. In the depicted in FIG. 5 and 6, an additional long element 15 is additionally made, applied to the side of the hand between the wrist and little finger to the back of the hand and then around the wrist.

Similarly to the previous embodiment, additional elements 17A, 17B are made, which can be applied so as to partially surround the wrist or extend to the palmar part or the palmar surface of the wrist, i.e. surface located on the side of the palm, thus completely covering the surface of the palm. The length of the additional element 15 is sufficient to at least partially surround the wrist, overlapping additional elements 17A and 17B, and thereby ensure their fixation.

As in the embodiment described with reference to FIG. 1-4, the central part 3 of the sheet forming the device or device 1 closes the palm almost completely; in particular, the length of the central part is such that when the user grabs a tool or equipment, such as a tennis racket, golf club or other tool or equipment, the perimeter edge P bounding the central part 3 is located in areas in which there is no pressure contact with the specified tool or inventory. Thus, the self-adhesive sheet does not detach from the palm of the hand, which is usually caused by mechanical action from the side of the tool or equipment along the line between the perimeter of the device and the skin, as well as perspiration between the self-adhesive sheet and the skin.

And in this case, too, the device or device is tightly fixed to the hand by means of additional elements 5-17B, bent and attached to the back of the hand and / or wrist, in areas where there is no contact with the tool or equipment, i.e. in areas in which the sheet forming the device or device 1 is not subject to mechanical compression from the side of the tool or equipment, which would lead to the detachment of the self-adhesive sheet P from the skin, starting from the edge of the perimeter.

The adhesive layer A deposited on the back of the self-adhesive sheet 1 is protected by a removable film. To facilitate application of the device or device 1 to the brush, due to its complex shape and wide surface, and in the embodiment of the invention shown in FIG. 5 and 6, the protective film also, instead of being made of one or two elements, is divided into a number of sections exceeding two limited by the separation or tear lines shown, in particular, in FIG. 5, which allows the user to apply the self-adhesive sheet to the hand region by region in accordance with preferred sequences, one of which is shown in FIG. 5 (the execution order corresponds to the sequence of reference positions), without the risk of sticking of various parts or additional elements of the self-adhesive film to each other before they are completely applied to the hand. In FIG. 1 illustrates, by way of example, a possible separation of the protective film, which is designated entirely by PP and covers the adhesive A on the surface 1A of the sheet forming the device or device 1 before use. PP1, PP2, .... PP22 respectively designate twenty segments or sections of the protective film, each of which can be removed separately and independently from each other. Namely, the user preferably removes one portion of the protective film at a time and immediately sticks the portion of the adhesive surface located beneath it, no longer covered by the protective film, to the skin and then proceeds to the subsequent portion.

Although the above specific embodiments of the invention are shown in the drawings and described generally in the above description with the distinctive features and characteristics related to various exemplary embodiments of the invention, those skilled in the art will understand that modifications, changes and exceptions are possible within the above-described innovative principles and concepts, as well as the advantages of the invention described in the attached claims. Thus, the scope of the described improvements should be determined only on the basis of the broadest interpretation of the attached claims in order to include all modifications, changes and exceptions. In addition, the scope of the invention includes any combination of the characteristics presented in one or more dependent claims and the characteristics of any of the independent claims.
