Patent Application
20210404235
Present invention is related to a building field assisting people in gaining ingress and egress from buildings more efficiently without need for the use of hands touching the door or handle. This invention is directed, and more particularly, toward adding a mechanical device or component for ease of operation to a person's effort in opening doors.
The foot operated door opener of the present invention is useful with different types of doors. It is particularly useful for opening a sliding door so that user's hands are free to hold objects or to provide a more sanitary way to open the door by reducing chances of touching the door. However, it will be appreciated that this invention is not limited to this particular field of use. Any reasonable alternation or substation shall not fail to fall within a protected scope of this invention.
Hand operated doors usually have door handles, knobs or hand pulls for grasping by hand to open the door. Although these components or devices seem easily to be operated, they are still quite inconvenient and frustrated for the user with both hands occupied with objects. Except calling for help from somebody nearby, the users need to put down all the holding objects to be able to open the door. This will waste a lot of time and cause a lot of troublesome to just simply open a door.
The other concern is unsanitary issue of these hand operated doors, especially the doors in public area. Their door knobs, handles or hand pulls are normally in unsanitary conditions due to contamination by many harmful bacteria and germs from outside environment and continuously touching by people. These devices are considered a perfect bed and vehicle for breeding and transmitting harmful substances to people by hand contact and causing a risk of spreading illness or disease. Especially during the outbreak of serious pandemic, it is very important and to be careful not to touch or contact any surface in the public area to avoid germs or bacterial infection.
Hence, it is eager to have a novel door opener that will overcome or substantially ameliorate at least one or more of the deficiencies of a prior art, or to at least provide an alternative solution to the problems. It is to be understood that, if any prior art information is referred to herein, such reference does not constitute an admission that the information forms part of the common general knowledge in the art.
In order to solve shortcomings of conventional door knob, handles or hand pulls which are not easily to be operated if both hands are occupied with objects or to avoid touching or contacting unsanitary doors, the present invention is provided for enable users to open the door by foot. The present invention cleverly uses folding structure that can be easily operated by foot for solving abovementioned problems and shortcomings of the conventional hand operated door.
According to a preferred aspect of the present invention, a door opener, which could be operated by foot, comprises a front panel and a rear panel. The front panel comprises a distal end and a proximal end. An anti-slippery structure is formed on the front panel. The anti-slippery structure comprises a friction surface or a structure facing up at an angle or protruded from a plane surface of the front panel. A hollow connecting tube is connected on an edge of the proximal end of the front panel. The rear panel also comprises a distal end and a proximal end. A rectangle gap is provided at a middle of an edge of the proximal end of the rear panel. Two fixing tubes formed at right and left side of the rectangle gap on the edge of the proximal end of the rear panel. The front panel and the rear panel are connected and pivotally rotated through connecting the hollow connecting tube of the front panel and the two fixing tubes of the real panel.
In accordance, the present invention has the following advantages.
By designing the anti-slippery structures on the present invention, these structures could provide user's foot enough tension or fiction to easily flip or rotate the front panel from the rear panel in a folded or unfolded condition and push or pull the door along with the foot. The door will be hence opened simply by user's foot without their hands touching it. This could benefit the user with both hands holding and carrying stuffs and also could prevent germs or bacterial infection by not touching the door.
The present invention on the other hand could also help those with weakened upper muscles, bone and joint problems, such as disable or arthritis. They can operate the present invention by foot through use of the weight from whole body without using hands and add mechanical advantage to the amount of force applied to the opener.
Many of the attendant features and advantages of the present invention will become better understood with reference to the following detailed description considered in connection with the accompanying figures and drawings.
The steps and the technical means adopted by the present invention to achieve the above and other objects can be best understood by referring to the following detailed description of the preferred embodiments and the accompanying drawings.
In order to make purposes, technical solutions, and advantages of the present invention to be clearer, the following content provides some preferred embodiments in accordance with the present invention.
Reference will now be made in detail to the present preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts. It is not intended to limit the method by the exemplary embodiments described herein. In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to attain a thorough understanding of the disclosed embodiments. It will be apparent, however, that one or more embodiments may be practiced without these specific details. As used in the description herein and throughout the claims that follow, the meaning of “a”, “an”, and “the” may include reference to the plural unless the context clearly dictates otherwise. Also, as used in the description herein and throughout the claims that follow, the terms “comprise or comprising”, “include or including”, “have or having”, “contain or containing” and the like are to be understood to be open-ended, i.e., to mean “including but not limited to”.
With reference to
The aforementioned anti-slippery structures 11 could be formed on or protruded from a surface of the front panel 10. For example, the anti-slippery structures 11 comprise an anti-slippery coating surface 114 with multiple clawlike extrusions 111, 112 and at least one protrusions 113 formed thereon. With reference to
With reference to
When assembly the front panel 10 and the rear panel 20 of the present invention, these two pieces are connected by its proximal end 14 and 29 at the pivot section 30. As shown in
In another preferred embodiment, the magnet component 40 could be further utilized accompanying with the foot operated door opener provided by the present invention. As shown in
With reference to
The above specification, examples, and data provide a complete description of the present disclosure and use of exemplary embodiments. Although various embodiments of the present disclosure have been described above with a certain degree of particularity, or with reference to one or more individual embodiments, those with ordinary skill in the art could make numerous alterations or modifications to the disclosed embodiments without departing from the spirit or scope of this disclosure.
