Definitions

• the present disclosed cleaning device comprises a first arm portion pivotally separated from a second arm portion, which supports a first cleaning portion.
• Cleaning window panes is laborious and time-consuming work, especially on high rise buildings, where washing glass is not only difficult but also dangerous, thus it requires the service of specialized personnel.
• US Patent 3,769,651 A number of cleaning devices are provided in the prior art, such as the window cleaning0 device disclosed in US Patent 3,769,651, which comprises a U-shaped holder with a handle attached to one end and a cleaning head used for the cleaning of external windows attached to the other.
• the cleaning device disclosed in US Patent 3,769,651 is incapable of effectively cleaning upper story windows, however.
• US Patent 5,007,753 discloses a window cleaning apparatus that has a cleaning head that is rotatable to any position when used on a window5 surface; however, the angle of the handle is not adjustable. As a result, the apparatus is not adapted to clean of exterior windows.
• the present disclosure provides a cleaning device, the cleaning device being adapted for the cleaning external windows and also the0 cleaning of external windows at different elevations. Moreover, the cleaning portion of the cleaning device achieves full contact with the glass surface, improving cleaning efficiency.
• the cleaning device comprises: a first arm portion having an adjustable length; a first cleaning portion; a second arm portion supporting the first cleaning portion; a rotating adjustable portion located between the first arm portion and the second arm5 portion wherein the first arm portion is rotatable in a predefined range about the second arm portion.
• the cleaning device further comprises: a second cleaning portion, said second cleaning portion being configured to mount detachably on the second arm portion.
• the second arm portion is made from a flexible material.
• the second arm portion takes the form of a "V" shape, and the second cleaning portion is mounted between the arms of the V-shaped second arm portion.
• the rotating adjustable portion has a button, and pressing said button causes the first arm portion to rotate about the second arm portion.
• hooks are disposed along the surface of the second cleaning portion, wherein the hooks are used for attachment of a cleaning cloth.
• the second cleaning portion can be used independently, or may be used in combination with the first cleaning portion.
• the predefined range is 0-180°.
• the cleaning device further comprises a bottle containing a foam cleaning agent is attached to said first arm portion.
• FIG. 1 is a front schematic view of on embodiment of a cleaning device
• FIG. 2 is a lateral schematic view of the cleaning device of FIG. 1 ;
• FIG. 3 is a schematic view of the predefined angle of first arm portion rotation
• FIG. 4 is an enlarged partial view of the first cleaning portion and second cleaning portion
• FIG. 5 is a schematic view of the rotating adjustable portion
• FIG. 6 is a cross-sectional view of the rotating adjustable portion
• FIG. 7 is a cross-sectional view of the rotating adjustable portion
• FIGS. 8-1 1 are schematic views of components of the rotating adjustable portion.
• the cleaning device of the present disclosure comprises: a first arm portion 4, the first arm portion 4 having an adjustable length; a first cleaning portion 5, the first cleaning portion 5 being adapted for the cleaning of glass surfaces; a second arm portion 1, said second arm portion 1 providing support to the first cleaning portion 5; a rotating adjustable portion 3, the rotating adjustable portion 3 being located between the first arm portion 4 and the second arm portion 1, the first arm portion 4 being rotatable in a predefined range about the second arm portion 1 by means of the rotating adjustable portion 3.
• the predefined range is 0-180°.
• the cleaning material mounted on the first cleaning portion 5 can be used for cleaning and also the absorption of liquid. During cleaning operations, the cleaning material can be detached when it becomes dirty, cleaned and then reattached to the first cleaning portion 5.
• the first arm portion 4 rotates about the second arm portion 1 to a predefined angle.
• the cleaning device can therefore be extended outside the building to clean the glass of external windows.
• the extendable rod of the first arm portion 4 can be used to adjust the length of the first arm portion and thereby clean the glass of external windows at different elevations.
• the second arm portion may take the form of a "V" shape and be made from a flexible material, the flexible material being a rubber, thermoplastic elastomer or other resilient material.
• the flexibility of the second arm portion 1 enables full contact between the first cleaning portion 5 and the glass surface, reducing labour and improving the efficiency of cleaning operations.
• the cleaning device further comprises a second cleaning portion 2, which is detachably mounted on the second arm portion 1.
• the second cleaning portion 2 is inserted between the arms of the second arm portion, as shown in Figure 4.
• the second cleaning portion 2 can be used in combination with the first cleaning portion 5 or may also be used independently. Hooks may be disposed along the surface of the second cleaning portion 2 for attaching a cleaning cloth.
• the cleaning cloth is typically a non- woven fabric or other cleaning cloth, the scraping action of which is used to remove dirt.
• the rotating adjustable portion 3 has a button, and pressing said button causes the first arm portion 4 to rotate about the second arm portion 1 in a predefined range.
• the cleaning device further comprises a bottle containing a foam cleaning agent attached to the first arm portion 4.
• the rotating adjustable portion 3 shown is comprised of the following components: a first arm connecting portion 31, a second arm connecting portion 32, a button 33, a locking piece 34 and a spring 35, as shown in Figures 5-11.
• the button 33 and locking piece 34 are fixed together, and connect the first arm connecting portion 31 to the second arm connecting portion 32.
• the elastic force of the spring 35 acts to insert the projecting portion 341 of the locking piece 34 into the recessed portion 321 of the second arm connecting portion 32 and the recessed portion 311 of the first arm connecting portion 31, locking the second arm connecting portion 32 and the first arm connecting portion 31 in place and preventing rotation; pressing the button 33 causes the projecting portion 341 of the locking piece 34 to slide outward, releasing the lock between the second arm connecting portion 32 and the first arm connecting portion 31, leaving them free to rotate.
• Consecutive and corresponding recessed portions are disposed in the interiors of the second arm connecting portion 32 and the first arm connecting portion 31, such that the second arm connecting portion 32 and the first arm connecting portion 31 can be locked at 30° intervals in a 0-180° range.
• An alternative number of recessed portions may also be disposed.
• 4 projecting portions may be disposed symmetrically on the locking piece.
• Method of use for the cleaning device transfer the foam cleaning agent onto the second cleaning portion 2, use the second cleaning portion 2 to perform cleaning operations on the glass surface, then rotate the device 180° and use the first cleaning portion to remove the water and debris.
• adjust the rotating adjustable portion rotating the first arm portion about the second arm portion to a predefined angle, adjust the length of the first arm portion according to the position of the external window, then extend the cleaning device outside the building to clean the external window.
