The present invention relates to a product for cleaning windows.
Window cleaning tools are known in the prior art. To date, window cleaning tools heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.
A variety of tools have been devised specifically to clean windows. Such tools are typically formed of a pad which is connected to an elongated handle. A cleaning element is attached to one side of the pad by various means including clips, straps, or hook and pile fasteners. However, each of these tools is specifically devised for a single type of cleaning operation and operates in a single plane of motion.
While such tools improve the reach of the user and enable the user to clean the lower edges of windows, it is believed that further improvements can be made to such window cleaning apparatus to make the cleaning apparatus easier to use, to provide easily detachable and interchangeable mounting of different shaped pads, as well as providing easy replacement of wet, soiled cleaning elements.
Therefore, there is a need for an apparatus to easily and ergonomically apply a force to clean or otherwise engage a glass surface or another surface and which overcomes some or all of the previously delineated drawbacks of the prior art.
In other words, while these devices fulfill their respective, particular objectives and requirements, the prior art does not disclose a combination window cleaning tool having a 360 degree range of motion coupled with a wiping blade and disposable microfiber cleaning cloths.
In this respect, the combination window cleaning tool according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of cleaning surfaces, in particular, glass surfaces.
In view of the foregoing disadvantages, the present invention has an objective to provide a new and novel product for cleaning windows.
The present invention comprises a handle, a base and a pivot joint. The handle has a proximal end and a distal end with distal end of handle being a forked yoke member.
The base has a top surface and a bottom surface. The top surface including a housing and a wiping blade. The bottom surface including interface projections.
A pivot joint connects the handle to the base. The pivot joint has a center with four legs extending outwardly from the center. Two of the legs forming a first pin and two of the legs forming a second pin. The first pin interfaces with the yoke member, and the second pin interfaces with the housing.
The pivot joint allows the handle to have a range of 360 degree motion with respect to the base and vice versa.
Another aspect of the housing is that the housing includes two housing members that are attached to the base. Each housing member has an aperture that is capable of receiving an end of the second pin.
Another aspect of the forked member is that the forked member also includes two apertures. Each aperture capable of receiving an end of the first pin.
The present invention also includes a disposable cleaning cloth. The cleaning cloth also includes interface projections that are compatible with the interface projections of the base. The cleaning cloth of the present invention is padded and is made from a microfiber material
The present invention is formed from a plastic or a like material. And the base is in the shape of a tear-drop.
Another aspect of the present invention is that the handle has a gripping portion located on its proximal end. The gripping portion has an ergonomic design and is made from rubber or like material. The gripping portion also has a loop located atop the gripping portion.
Preferred embodiments of the invention are described below with reference to the drawings, wherein like numerals are used to refer to the same or similar elements.
The present invention is a combination window cleaning tool having a 360 degree range of motion coupled with a wiping blade and disposable microfiber cleaning cloths.
As seen in
The handle 11 includes the forked yoke member 15 and gripping portion 16.
The handle 11 is about 4 to 12 inches in length and has the greatest circumference about midway along the gripping portion 16. The gripping portion 16 comprises about ⅓ of the entire length of the handle 11. The shortest circumference is found on the handle 11 at a position between the gripping portion 16 and the forked yoke member 15. The circumference of the handle 11 gradually decreases longitudinally from the forked yoke member 15 to midway along the handle 11, then gradually increases to midway along the gripping portion 16. The circumference of the gripping portion 16 gradually decreases again from midway along the gripping portion 16 to the loop 17.
The gripping portion 16 has an ergonomic design and is made from a soft rubber or silicone so that it has a comfortable grip. Atop the gripping portion 16 is a loop used for hanging the cleaning device 10 from a hook or any other hanging device. The interior diameter of the loop is about ¼ the length of the gripping portion 16 but may be a different size. The thickness of the loop 17 is about ½ the distance of its interior diameter. The shape of the loop 17 is round, but may be a different shape. The loop 17 is made from the same material as the gripping portion 16, but other materials may be used. The loop 17 also offers the user with added protection by not allowing the top of the handle 11 to mistakenly scratch or push into an unintended object.
The base 12 includes a top surface 20 and a bottom surface 21. The top surface 20 includes a housing 19 and a wiping blade 14. The base 12 is in a teardrop configuration but any configuration, such as a square, rectangle, or circle may be used. The teardrop configuration of the base 12 gradually increases in width from the rounded triangular point at the distal end 43 of base 12 at about a 45° angle until it reaches its greatest width about midway to the proximal end 42 of base 12 and maintains that width up to the wiping blade 14.
The base 12 is approximately 2-12 inches in length and about 2-6 inches at its greatest width. The base is 2-12 centimeters in height.
The cleaning device 10 also has a removable cleaning cloth 18 that is attached to the bottom 21 of the base 12. The cleaning cloth 18 attaches to the base 12 via interface protrusions (discussed below) that interact with protrusions (discussed below) of the base 12.
The cleaning cloth 18 is made from a microfiber and is also disposable. The cleaning cloth 18 mimics the shape of the base 12 but is slightly larger than the base 12 in that it extends equally beyond all sides of the base 12 such that the width of one side of the extended portion of the cleaning cloth 18 is about 1/12 the width of the widest portion of the base 12. This allows room for error when applying the cloth 18 to the base 12. The cleaning cloth 18 also may come dry or may have a cleaning fluid already soaked in its fiber.
The pivot joint 13 is also shown in
The top surface 20 also has a wiping blade 14. The wiping blade 14 is used for wiping excess fluid from a cleaning surface. The wiping blade 14 is made from a resiliently flexible rubber or plastic material. The wiping blade 14 is formed with a parabolic gradient of about 90° with the base 12 so that the wiping blade 14 has a surface that makes better contact with the cleaning surface.
The wiping blade 14 is located at the proximal end 42 of the base 12. The wiping blade 14 traverses the entire width of the proximal end 42 of the base 12 and extends vertically outwardly, relative to the top surface 20, a distance of about 1/16 the length of the base 12. The wiping blade 14 is made from a resilient material, such as rubber or silicone, so that it does not wear out, but can be made of another material.
a and 7b show the interface projections 23 and 41 for the base 12 and cleaning cloth 18 respectively. In use the T-shaped projections 23 are inserted into a mesh material 41 of the cleaning cloth 18 when pressed together. The T-shaped projections 23 are present ubiquitously on the bottom 21 of the base 12 and aligned linearly with respect to each other. Once inserted, the cleaning cloth 18 will stay adhered to the base 12 until a user pulls the cloth 18 from the base 12.
In use, a user will hold the cleaning device 10 by the gripping portion 16 and will apply the cleaning cloth 18 to the bottom 21 of the base 12. The user will then apply the cloth 18 to a surface to be cleaned. The cleaning device 10 will allow a user to position the cleaning device 10 at many different angles so that, if the shape of the cleaning surface changes, the user does not need to reposition the cleaning device 10 because the angle of motion of the handle 11 with respect to the base 12 will change. This allows for easier cleaning of oddly shaped surface, such a car windshield.
It is readily apparent that the above-described cleaning device meets all of the objects mentioned above and has the advantage of wide commercial and residential utility. It should be understood that the specific form of the invention hereinabove described is intended to be representative only, as certain modifications within the scope of these teaching will be apparent to those skilled in the art.
Accordingly, reference should be made to the following claims in determining the full scope of the invention.
