[0001] The present disclosure relates generally to door opener, and more particularly, the present disclosure provides an antibacterial no touch door opening device that can be used to grasp contaminated surfaces such as door handles and the like.

BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Nowadays each and every person is living in the fear of germs infection. The germs are being communicable to human beings through different kind of materials like metal, wood, plastics, stainless steel, aluminum, copper, glass, ceramic, fabrics etc. as well as through human beings themselves. The germs can survive for long periods of time on various surfaces; the time of survivals depends on the material of the surface. Therefore, it becomes important to maintain distance from human beings as well as from the surfaces of different kind of objects which we use in daily life to avoid infection.
[0004] The use of public places usually involves touching surfaces that other people have previously contacted, potentially depositing their germs thereon which can spread germs and disease. Such public places may include door handles in restrooms and keypads for PIN numbers and the like. These are the necessity for most people who are using lift buttons, touch screens of ATM, access control, visiting offices, airport, and shopping malls. The door handles in public restrooms and doors in public buildings can be a major source of spreading germs. In addition, the use of public ATM's and, POS require a user to touch a keypad that is touched by many other users, and these are not disinfected frequently. And, to reduce the chances of getting infected, it becomes imperative to clean and disinfect common surfaces and objects in the home, office, public contact areas on daily basis. However, in practical terms it is not possible to clean the commercial surfaces especially door handles, keypads of ATM, lift buttons and the likes of public places after every use.
[0005] The need of contactless door openers thus comes into play. The door opener assists in reducing the need of touch surfaces like door handles, keypads of ATM, lift buttons and the likes of public places, where germs are more active, because these surfaces are touched by a plurality of people.
[0006] Many contactless door openers exist in the market in different shape and sizes. It has been observed that the available contactless door openers facilitate in opening the doors without touching them directly, but after using the door openers there is no facility to disinfect the door openers. Consequently, when the door opener is exposed to an infected surface they get infected, and automatically disinfecting the door opener is not available. The available contactless door openers are generally made of metal and tend to put scratches on the doors and the keypads. Also, the average length of commercial products available is 75 mm which is not compact. Most of them have protruding edges that can hurt an individual carrying them.
[0007] There is a need to overcome above mentioned problem of stated arts by bringing a solution which facilitates automatically disinfecting feature with the door opener. The solution provides the door opener which is compact and light weight that enables the user to carry it easily daily. Also, the device provides rubberized materials on the device that enables the user to operate public keypads, buttons and the likes without damaging them.

[0075] As used herein, and unless the context dictates otherwise, the term "coupled to" is intended to include both direct coupling (in which two elements that are coupled to each other contact each other) and indirect coupling (in which at least one additional element is located between the two elements). Therefore, the terms "coupled to" and "coupled with" are used synonymously. Within the context of this document terms "coupled to" and "coupled with" are also used euphemistically to mean “communicatively coupled with” over a network, where two or more devices are able to exchange data with each other over the network, possibly via one or more intermediary device.
[0076] It should be apparent to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, ` components, or steps that are not expressly referenced.
[0077] While the foregoing describes various embodiments of the invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof. The scope of the invention is determined by the claims that follow. The invention is not limited to the described embodiments, versions or examples, which are included to enable a person having ordinary skill in the art to make and use the invention when combined with information and knowledge available to the person having ordinary skill in the art.
