Description

SUMMARY

The present invention refers to a device for manipulating light objects made of different materials, of flat shapes even with large surfaces and of various shapes of small dimensions, such as: leafing through books, newspapers, notebooks, magazines; count and / or transfer sheets, laminates, plates of a ream; take needles, hair, seeds, coins, and any other object that is difficult to take with only the use of the hands.

These operations are carried out through a device consisting of a double-sided adhesive film or net that attaches with the inner part, to the tip of the index finger or to other affected parts of the hand and, subsequently, is pressed on the object to be manipulated which remains attached to the fingertip. thanks to its external adhesive surface that can be repositioned for at least part of its surface.

The object thus attached to the fingertip is removed and brought to a certain position that allows the intervention of at least one other finger of the hands and / or other means to transfer it to its final place.

The present invention refers to a device for facilitating the manipulation of light objects, made of different materials, such as: leafing through books, newspapers, magazines, notebooks; count and / or transfer sheets, plates, laminates of a ream; scroll through documents; take coins, seeds, needles, and any other object that is difficult to take with only the use of the hands.

Various devices for handling sheets are known in the known art, as indicated in US Patent 1975000554676, where a device for handling sheets, especially paper ones, is described, consisting of two layers, one of which adhesive which sticks to the fingertip and the other, opposite , of rubbery material that does not slip on the paper; but this device is less fast and effective than the one related to the present invention, it is difficult to use it to handle very thin and glossy sheets, especially if made of plastic, it cannot be used to handle sheets, plates and rigid laminates, other thicker sheets and small objects of various shapes, and insert it directly into books, newspapers, notebooks, etc.

Another disadvantage is given by the fact that this device requires more time to fix it on the fingertip and produces very large folds at the corners of the sheets to be handled.

The present invention eliminates the aforementioned disadvantages due to the fact that, to manipulate sheets, laminates, plates and small objects of various shapes, made of any kind of material, a device is used consisting of a double-sided adhesive film or net which sticks, with the internal part, to the tip of the index finger or to other parts of the hand, and, subsequently, it is pressed on the object to be manipulated which remains attached to the fingertip thanks to its external removable adhesive surface for at least part of its surface. After that, the object attached to the fingertip through this device is brought into a certain position that allows the intervention of at least one other finger of the hands and / or other means to transfer it to its final place.

The adhesive materials for making the device relating to the present invention and which meet the needs for which they are used, namely those of attaching the device to the fingertip without letting it detach during use but, easily, voluntarily and without damaging the physical structure -chemistry of the objects to be handled, by gently attaching and detaching them without leaving traces, are numerous, such as adhesives for plasters or adhesive tapes, for removable labels or post-its, repositionable screen printing adhesives, rubbers and repositionable adhesive pastes already used for gaskets, sealants, to fix different objects, etc ..

The adhesive materials mainly used to make the external part of the device can be combined with other materials or substances. For example: if you use a water-based, pressure sensitive adhesive with a higher tack level and therefore with a higher adhesion force, such as that used for screen printing consisting of epoxidized phenolic novolac resin and thinner acrylate, in combination with various types of powder, for example talcum powder, a removable and easily printable adhesive paste is obtained that perfectly meets the needs and purpose for which it was created.

The same result is obtained by mixing the adhesive with acetic silicone, gum arabic or with polymers af acrylic and methacrylic esters in toulene dichloropropane, to which mixture thus obtained can also be added talcum powder to obtain a repositionable adhesive rubber with the same qualities previously described. .

If the adhesive is diluted with water or alcohol, the solution obtained can be applied directly to the fingertip.

The structure that constitutes the device can be compact, spongy, permeable or waterproof, and may have a multitude of air microbillocins thrown inside.

The films that make up the device can be of a single layer using rubber or repositionable adhesive paste that can be printed on a silicone sheet with the use, for example, of screen printing or with the help of a perforated plate whose holes are the shape of the devices and whose thickness determines the thickness of the devices themselves. Once dried, a protective silicone sheet is applied to them or they are rolled up if they have been printed on a bisiliconised tape. After detaching the protective silicone sheet and releasing the internal adhesive part of the device, which sticks to the fingertip by applying a certain pressure on it, the device ready for use is thus obtained in a very practical and simple way.

For example: to leaf through a book, you must press lightly with the fingertip, to which the device is fixed, on a corner of the sheet, lift it gently and, with the help of the middle finger, turn it and at the same time detach it from the device, i.e. from the fingertip itself; to transfer a sheet of a ream, you press with your fingertip at the base of the sheet, pulling it forward and / or lifting it and with the help of the thumb and / or the other hand it is transferred to the desired place; to transfer a plate or laminate, heavier than a common sheet, from a stack positioned horizontally, a larger device is used which is pressed with the base of the thumb, after which, by pressing on the right corner of the plate, it is turned to the right horizontally, tightened with the fingers of the same hand, pulled forward while continuing to rotate it to the right, positioned in such a way that it can be taken with both hands, detached from the palm and, with the help of both hands hands, moved to its final place; to take a small object, of various shapes, press on it with the fingertip, to which the device is fixed, lift it and take it with the other hand; etc..

At the end of its use, the device is detached from the fingertip by pressing it on an adhesive surface, on which it remains permanently attached.

The double-sided adhesive film that constitutes the device can also be made of two layers and is similar to the device described above: it differs only in that the internal part consists of an adhesive layer of the type used for plasters.

Another variant of the device consists of a removable double-sided adhesive film which, after drying, is quite resistant. In this case, a net or a multitude of non-adhesive particles is inserted into the outer part of the film, and a non-adhesive peripheral strip can also be inserted. To make this device, therefore, first the non-adhesive parts are printed on the siliconized sheet and, afterwards, a layer of removable adhesive is printed on them.

The variant in three layers is characterized by the fact that the double-sided adhesive film consists of a support made of easily foldable material on which, on the inside, a layer of adhesive is applied that adheres well to the skin and, on the outside, a repositionable adhesive surface, such as the one used for Post-Its.

Depending on the device to be printed, the order of the printing steps may change. In fact, you can first print a layer of repositional adhesive paste or gum and, after its drying, a central layer of a plasticizer or a resin that is non-adhesive once dried but resistant and easily foldable, which layer can have a surface greater than the first, and finally a layer of adhesive is printed such as, for example, the one used for plasters. Or, you can first print a multitude of non-adhesive particles or mesh, then, on the same layer another repositionable adhesive is printed, in addition on this another one of plasticizer or non-adhesive resin which can have a larger surface than the first two, and, finally, another layer of adhesive is printed on them which adheres well to the skin. Each printed layer, before printing a new overlying layer, must be well dried.

The device can also consist of a set of adhesive particles, of the order of microns, which fit between the lines of the fingerprints. Said adhesive particles can be pulverized on a siliconized sheet and covered by another siliconized sheet once dried.

To use the device thus created, it is necessary to press with the fingertip on said adhesive particles, after having removed the silicone-coated protective sheet.

The device subject of the invention can also be made of an absorbent and easily foldable material such as canvas, polyurethane sponge, absorbent paper, paper used for handkerchiefs, etc., which is impregnated in a repositionable adhesive with high cohesive strength. After the adhesive dries, a resistant double-sided adhesive film is obtained, with all the qualities necessary to achieve the purpose for which it was created.

Instead of the absorbent material, a net or a simple thread can be used, also made of very fine, absorbent or non-absorbent synthetic fibers.

The devices described so far can be stored in a system of one or more devices between two protective sheets, for example silicone-coated sheets, easily detachable when needed, by first releasing the internal adhesive part that sticks to the fingertip by applying a certain pressure to the same and obtaining so in a very practical way, the device is ready for use.

This system for storing these devices allows them to be inserted directly into books, notebooks, magazines, reams of paper, metal, canvas, plastic, etc., and in any other place that requires their use, thus always having them at hand. when you need it.

To make the device adhere well to the fingertip, the latter can be degreased by rubbing it on a surface, such as absorbent paper, or cleaned with alcohol.

After using the same device several times, if the adhesion forces to the object to be handled decrease, the external part of the device can be renewed by rubbing it, without detaching it from the fingertip, on a rough, satin surface or by washing it with alcohol.

At the end of use, if the film no longer works, it can be detached from the fingertip by pressing it on an adhesive surface.

The packages that keep the devices are equipped with the satin surface to renew the film, the adhesive surface to detach the film from the fingertip and the absorbent surface to degrease the fingertip before its use.

To improve the adhesion forces of the device and before making it adhere to the fingertip, the latter must be degreased with alcohol or a layer of soluble rosin, gum arabic or other substance that adheres well to the skin must be applied to it.

The devices can also be stored on tapes, bisiliconised supports rolled, in free form or rolled into cassettes, which make them easier to take and equipped with a small tank in which an absorbent material impregnated in alcohol is contained. The tank is equipped with a porous head made, for example, of natural or synthetic fiber with which the fingertip is degreased. Likewise, the cassette can be equipped with another reservoir where the substance adhering to the skin is found. The tank head is equipped with an airtight cap.

The cassette, on the outside, has satin surfaces on which the double-sided adhesive film can be renewed and a cap that closes the adhesive surface on which the film is detached from the fingertip.

Another system for realizing the device subject of the invention is to apply with different procedures or tools, a film of removable adhesive directly on the fingertip or on other interested parts of the hand, which must dry instantly and must be very thin, of the order of a few microns, such as to perfectly copy the lines of the fingerprints and, precisely for this reason, this film does not detach from the finger during use and does not damage the objects handled since the surface that adheres to the fingertip on the inside is much wider than to the external one that attaches the sheets and that remains positioned on the top of the lines of the fingerprints itself.

A tool for printing double-sided adhesive film directly on the fingertip consists of a reservoir that contains an absorbent material impregnated in a repositionable adhesive diluted in alcohol, water or another suitable solvent. The reservoir is equipped with a porous head through which the double-sided adhesive film is printed, an airtight cap and an adhesive surface to detach the film from the finger provided with a protective cap.
