SANITARY GRIPPING DEVICE
A gripping device defined by flexible sheet of material for use to be temporarily wrapped about a handle of a device, such that a person's hand grips the sheet instead of directly gripping the handle, for sanitary purposes, preventing transfer to the person's hand or hands of microbes or bacteria that are possibly disposed on the handle. The sheet temporarily self-secures to the handle but is removable therefrom. At least the handle-engaging surface of the sheet is slip resistant. The sheets may be dispensed from a coil thereof that is conveniently located, and may be disposable.
This application claims the benefit of U.S. Provisional Patent Application No. 61/523,619, filed on Aug. 15, 2011, the contents of which are incorporated by reference.
FIELD OF THE INVENTIONThis relates to the field of personal hygiene accessories and more particularly to sanitary devices to prevent transmission of microbes when it is required to manually grip handles and the like in public areas.
BACKGROUND OF THE INVENTIONIt is well known that microbes become deposited and thrive on surfaces of articles that are gripped by various different people and thereby can become transferred from person to person. Many such articles are handled very frequently by different persons, including handles of shopping carts in stores and supermarkets, support poles of public transportation vehicles, and also free weights and gymnasium equipment in physical fitness centers or sporting goods stores. Even when such surfaces are often sanitarily wiped and cleaned using soaps and/or antibacterial or antimicrobial wipes or solutions, microbes can quickly return, carried and deposited by the next person to touch them, and be transferred to the next person thereafter, and so on. While many people take steps to try to limit microbes on their hands, for example, by frequently washing their hands or utilizing sanitary items such as treated wipes or small dispensers of antimicrobial solutions such as Purell® polyvinyl alcohol cleanser (trademark of GOJO Industries, Inc.) that they carry with them or which are posted in public areas like stores, hospitals and the like, such precautions are often forgotten or may be inconvenient at times. Some people even choose to wear gloves at all times when in public, however, such can be very inconvenient.
BRIEF SUMMARY OF THE INVENTIONBriefly, the present invention provides a griping device defined by a small flexible sheet of material used by a person to be easily interposed as a barrier between the hand or hands and the surface of an article to be gripped, such as a shopping cart handle, for example. Preferably, the sheet would be of a material such as rubber or gel or open-celled foam, and at least the one surface of the sheet to be placed adjacent the article to be gripped, would have a slip resistant property, and preferably both surfaces would be slip resistant. The article-adjacent surface could have a weak adhesive to facilitate surface adherence, but would not leave any residue when removed. Also, preferably, after application to the target surface, the sheet would remain in place if temporarily released from being gripped. Such sheets would be inexpensive and could be disposable, or they could be reusable. Unlike the antimicrobial wipes of the prior art, the sheets of the present invention need have no antimicrobial solutions, compounds or characteristics, to be effective for their intended prophylactic purpose.
One embodiment is a square or rectangular thin sheet of material that is easily rolled around a cylindrical handle into a coil. Such sheets of material could be carried by a person, or could be dispensed from a dispenser stand placed near the shopping cart corral or barbell area, where the sheets are provided in a roll and easily detachable by use of perforations.
Another embodiment could be a mitt-shaped sheet having a finger-strap or thumb-band, or both, affixed to the hand-engageable surface of the sheet. Such a sheet could be provided for each hand, and thus be configured accordingly, with the finger-strap and thumb-band to be positioned and sized appropriately.
The accompanying drawings, which are incorporated herein and constitute part of this specification, illustrate exemplary embodiments of the invention, and, together with the general description given above and the detailed description given below, serve to explain the features of the invention. In the drawings:
In the drawings, like numerals indicate like elements throughout. Certain terminology is used herein for convenience only and is not to be taken as a limitation on the present invention. The term “handle” is used herein to include without limitation the portion of a device adapted and intended to be gripped by hand to move or hold the device, or part thereof, or to enable a person to secure themselves in position, where the device may be, without limitation, a hand-grippable pole of a vehicle for public transportation such as a bus, train or trolley, a shopping cart handle, a shopping basket handle, a free weight shaft or gymnasium equipment, and the like. The terminology includes the words specifically mentioned, derivatives thereof and words of similar import. The terms and expressions used herein, and the embodiments illustrated below, are not intended to be exhaustive or to limit the invention to the precise form disclosed. These terms, expressions and embodiments are chosen and described to best explain the principle of the invention and its application and practical use and to enable others skilled in the art to best utilize the invention.
The gripping device 10 is manufactured from a flexible material and defines a handle-engaging surface 14 and a hand-engaging surface 16. As described herein, the handle-engaging surface 14 and the hand-engaging surface 16 may have some similar properties and some distinct properties. The gripping device 10 may be manufactured from a single layer of material with treatments or the like applied to the surfaces 14, 16 to achieve distinct properties or the gripping device may be manufactured from two or more layers secured to one another, with the different layers providing different properties, or a combination thereof. As some examples, without limiting, the gripping device 10 itself, or individual layers of the gripping device 10, may be a soft flexible material such as of rubber, gel, or open or closed celled foam. One or both surfaces 14, 16 may be maid from an antimicrobial material or have an antimicrobial applied thereto.
Preferably, the handle-engaging surface 14 has a property of slip resistance and/or stickiness or tackiness for mild adhesion. The slip resistance may be achieved by providing a surface texture on the handle-engaging surface 14, for example, bumps, grooves or the like. Alternatively or additionally, the handle-engaging surface 14 may have a level of stickiness or tackiness such that the gripping device 10 will stick to the handle 100 or to itself when the gripping device 10 is wrapped about a handle 100 as illustrated in
The stickiness or tackiness may be achieved by the inherent properties of the material used to manufacture the handle-engaging surface 14. For example, the handle-engaging surface 14 may be formed from expanded vinyl material which provides a good frictional or “tacky” quality that remains disposed on the surface of the gripping device 10, but does not transfer such tackiness to the handle 100. Alternatively or additionally, the tackiness may be achieved through an adhesive or the like applied to the surface 14. An exemplary adhesive is a microsphere adhesive or other repositionable glue. It is desirable that if the handle-engaging surface 14 has a tackiness, no adhesive residue remains on handle 100 when gripping device 10 is removed.
In applications wherein the edges 12, 13 overlap as illustrated in
The hand-engaging surface 16 preferably does not have sticky or tacky properties, however, in some applications it may be desired. The hand-engaging surface 16 preferably provides a soft gripping surface which may be smooth or textured. Advantageously, the handle-engaging surface 14 and the hand-engaging surface 16 have different colors or other indicia 15 to provide a visual indicator to the user to increase the likelihood that the user will only handle the hand-engaging surface 16 which is intended to remain microbial free. The gripping device 10 is preferably reusable many times and is easily carried by a person. In this regard, it is preferable that the gripping device 10 is made from a washable material so that it can be cleaned occasionally.
