Description
- This application claims the benefit of Document Disclosure No. 424972, dated Oct. 1, 1997, and No. 425983, dated Oct. 14, 1997.
- 1. Field of the Invention
- This invention relates generally to cleaning devices, and more particularly, to a novel device for both cleaning and removing static charge from cathode ray tube (CRT) screens.
- 2. Description of Related Art
- Cleaning aids and devices, such as brushes, squeegees, ice and snow scrapers are known. These devices are widely used to clean windows and other areas in all types of buildings, and to clean and/or scrape windshields and other windows in vehicles.
- However, these known devices are not capable of, and cannot be adapted for, cleaning and/or removing static charge from CRT screens. CRT screens are contained, for example, in computer monitors, television sets, and other video display devices. As the public becomes more familiar with and uses video display devices, such as in desk top monitors, portable computers, TV sets, etc., the need for cleaning the screens of such devices increases. Furthermore, such devices for cleaning such screens should be capable of quickly and easily cleaning the screens, and at the same time removing static charge therefrom. There, therefore, exists a need in the art for an inexpensive, easy to manufacture and use device for cleaning and removing static charge from video display device screens.
- Known prior art devices for cleaning windows and the like are shown in U.S. Pat. Nos. 763,888 to Hayden, 1,555,417 to Johnston, 2,154,373 to Bulleigh, 2,526,468 to Frye, 2,977,127 to Mertes, 2,958,886 to Taylor, 3,965,520 to Maier, 4,075,730 to Siemund, 4,317,250 to Shutts, 4,430,769 to Bergstrom, 4,495,668 to Adams, 5,140,717 to Castaliola, 5,321,868 and 5,528,793 to Schbot.
- Additionally, U.S. Pat. Nos. 3,289,236 to Salka and 3,333,289 to Maughan show, respectively, a painter's edging tool having a
paint applying element 26, 26 a and an oval shaped cleaning brush having conical shaped bristles for cleaning in corners. - While the foregoing mentioned prior art devices provide improvements in the cleaning art, there still remains the need in the art for an easy to use, low-cost device for use in cleaning and/or removing static charge from CRT screens. The novel and simplified device of the present invention allows a user to easily and quickly clean a CRT screen by drawing or moving the device back and forth across a screen face with a cleaning brush thereof in contact with the screen. None of the prior art devices discussed above are applicable to cleaning a CRT screen nor could they be used to remove static charge from a CRT screen.
- Accordingly, it is a general object of the present invention to provide an improved cleaning device. It is a particular object of the present invention to provide a squeegee like cleaning tool for cleaning computer screens and the like. It is a still more particular object of the present invention to provide a hand held CRT screen cleaning device which is moved over the screen a multiple of times to clean the screen and remove static charge therefrom. And, it is a still more particular object of the present invention to provide a hand held CRT screen cleaning device having an elongated brush mounted on a body, which body is easily gripped between the thumb and one or more fingers of a single hand of a user for rubbing over a CRT screen to clean the screen and remove static charge therefrom.
- In accordance with one aspect of the invention, there is provided a hand held CRT screen cleaning tool having a body with an elongated bottom portion secured to a top gripping portion. An elongated brush or cleaning element is secured to the elongated bottom portion for placement on and cleaning of a CRT screen by dragging the elongated brush a multiple of times across the CRT screen.
- The objects and features of the present invention, which are believed to be novel, are set forth with particularity in the appended claims. The present invention, both as to its organization and manner of operation, together with further objects and advantages, may best be understood by reference to the following description, taken in connection with the accompanying drawings, wherein:
- FIG. 1 is a front elevational view of a computer monitor showing a hand of a user holding a screen cleaning device of the present invention against the screen and then dragging it across the screen of the monitor during cleaning; and
- FIG. 2 is a side elevational view, partially in cross-section of a preferred embodiment of the screen cleaning device of the present invention.
- The following description is provided to enable any person skilled in the art to make and use the invention and sets forth the best modes contemplated by the inventors of carrying out their invention. Various modifications, however, will remain readily apparent to those skilled in the art, since the generic principles of the present invention have been defined herein specifically to provide for a novel and improved hand held screen cleaning device, generally indicated by
numeral 10. - Although the hand held
screen cleaning device 10 may take any desired shape, and be made from any available or desired material, it is preferably formed from a single piece of plastic or other similar material, in the form of a squeegee-type device. The hand heldcleaning device 10 is comprised of a body 11 having a smaller first or upper gripping portion orsection 12, a second or lower elongated cleaning portion orsection 14, and a connecting orneck portion 15. Theelongated cleaning portion 14 is preferably formed in a generally rectangular shape having contoured corners and connected to theneck portion 15 centrally thereof. An elongated brush orcleaning element 16 is secured to a first orrear side 18, as by means of a holding element 17 captured in anelongated opening 21, formed along anangled edge 20 of the elongated lower portion 14 (see FIG. 2). The angle of theedge 20, to which the holding element 17 ofbrush 16 is bonded or secured, as by an adhesive or the like, is chosen so thatbristles 22 of thecleaning brush 16 extend at a selected angle to the hand heldcleaning device 10 while the device is gripped by ahand 24 of a user during cleaning aCRT screen 26 of a computer monitor or the like 28 (see FIG. 1). The angle of theedge 20 may vary depending on the size of the hand helddevice 10, thebrush 16 and the length of thebristles 22. That is, the hand helddevice 10 andbrush 16 are sized and dimensioned so that the angle of the edge and the length of the brush are sufficient when handled or manipulated by thesingle hand 24 to be easily and quickly drawn across thescreen 26 to clean and remove the static charge from anarea 30. - The rear face or
side 18 of the hand heldcleaning device 10 preferably includes a raised portion or bead 32 along its outer edge to add strength thereto, while a front face orsurface 19 thereof is preferably be flat. In this manner thefront face 19 may contain advertising, a design, printing, or the like, or may be contoured or otherwise decorated to allow it to be used as an advertising specialty or promotional device. - As shown in FIG. 1, the hand held
cleaning device 10 is used to clean and remove static charge from theCRT screen 26. This is accomplished by the user grasping the grippingportion 12 inhand 24, between the thumb and one or more fingers thereof. Thehand 24 easily presses thebristles 22 ofbrush 16 against theCRT screen 26 and moves the hand heldcleaning device 10 from afirst edge 34 of themonitor 28 overarea 30 until the cleaning device reaches a second edge 36 ofmonitor 28. Thecleaning device 10 is then moved back and forth across thescreen 26, in the same type of swiping motion to clean and remove static charge from the remainder of the screen. - It is obvious that a user of the hand held
cleaning device 10, will have to move the device over the screen with thebristles 22 in contact therewith a number of times, depending on the size of thedevice 10 and the size and shape of thescreen 26. As discussed above, thecleaning device 10 andbrush 16 are sized and dimensioned so that the device may be easily gripped by thehand 24 with thebristles 22 pressed against and capable of following any curvature of the screen over which it is being drawn. Thebristles 22 andbrush 16 are preferably formed from a resilient material, such as Nylon, to allow static charge to be removed, and with the bristles being of sufficient length to clean and conform to a curved screen surface for more efficient and thorough cleaning thereof. - When not in use, the hand held
cleaning device 10 may be stored out of the way, as by being removably secured to a corner of thecomputer monitor 28, by a removable securing means 38, such as a loop and fastener system referred to by the trademark VELCRO. This securing means 38 may be secured to therear surface 18 of the cleaning device, as best shown in FIG. 2. - It therefore can be seen that the present invention provides a simple and easy to manufacture and use hand held cleaning device for cleaning and removing static charge from a screen of a computer monitor or other video display device. It is particularly useful by one hand of a user to be dragged or drawn multiple times over a CRT screen for efficient and quick cleaning thereof. Furthermore, the device may take any shape so as to be compatible with its surroundings and may have advertising, a design, or other materials, such as a logo applied to an outer side thereof to increase the aesthetics thereof.
- Those skilled in the art will appreciate that various adaptations and modifications of the just-described preferred embodiments can be configured without departing from the scope and spirit of the invention. Therefore, it is to be understood that, within the scope of the appended claims, the invention may be practiced other than as specifically described herein.
