Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a multi-functional window washing and wiping device, and particularly to a window washing device which may achieve the purpose of washing glass windows in buildings without the risk of having window washers hang in mid-air. 
     2. Description of Related Art 
     Because glass technology is advanced, and because glass has high penetrability, and is sparkling, clean, beautiful and modern, it is well suited for exterior walls or glass shutters in buildings. After long-term exposure to wind and rain, however, glass windows may easily get soiled with grime and water stains, which may affect the outward appearance of buildings as well as city appearance. Therefore, glass windows need regular washing and maintenance. Currently, glass exterior walls or glass windows are manually cleaned in most cases. Personnel access exterior walls of a building by hanging on a platform and wash the walls on the moving platform. This existing method of window washing is highly risky because it is performed in mid-air and the platform is shaky. This is not an easy job for everyone, and therefore there is often a shortage of manpower. It is impossible for inhabitants to clean their own windows, either. In view of the foregoing, after laborious research and experiments, the applicant of the present invention has devised a multi-functional window washing and wiping device which may reduce the risk of having window washers hang in mid-air. 
     SUMMARY OF THE INVENTION 
     A primary purpose of the present invention is to provide a multi-functional window washing and wiping device which may achieve the purpose of washing glass windows in buildings without the risk of having window washers hang in mid-air. 
     The foregoing multi-functional window washing and wiping device comprises a device body and a retractable rod connected to the device body, wherein on the device body are disposed a toothed gear assembly comprising a plurality of toothed gears and a vortex rod for driving the toothed gear assembly, whose two ends are pivotally connected to wheels disposed on two sides of the device body.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Please refer both to  FIG. 1  and  FIG. 2 , as well as  FIG. 3 , showing a three-dimensional view, a three-dimensional exploded view, and a view of a transmission structure according to the present invention. As the figures show, a multi-functional window washing and wiping device according to the present invention comprises a device body  1  and a retractable rod  2  connected to the device body  1 , wherein on a rear rim of the device body I is disposed a protruding ear  11  for pivotally connecting the device body  1  to the retractable rod  2 . In an interior of the device body  1  is disposed a toothed gear assembly  3  comprising a plurality of toothed gears. In the present embodiment, the toothed gear assembly  3  comprises at least a transmission gear  31 , two driven gears  32  meshed with the transmission gear  31 , and two rotating discs  33  fixedly disposed on the two driven gears  32 . Through holes going through a top of the device body  1  are respectively disposed at centers of the two driven gears  32  and two rotating discs  3  to be respectively connected with tube bodies  34  and  35  for allowing a cleaning tool  4  such as a brush, a sponge or a piece of cloth to be disposed on the two rotating discs  3  (fixed by attaching two hood-and-loop fasteners to each other). 
     The transmission gear  31  of the toothed gear assembly  3  is meshed with a vortex rod  36 . Wheels  37  are pivotally connected on two ends of the vortex rod  36  respectively, protruding and exposed on two sides of the device body  1 . When moving the device body  1  to rotate the wheels  37 , the vortex rod  36  is driven to drive the entire toothed gear assembly  3  so that the cleaning tool  4  disposed on the two rotating discs  33  is rotated. Above the device body  1  is further disposed a motor  38  and a transferring member  381 . By the rotating and switching of the transferring member  381 , a transmission shaft of the motor  38  is pivotally connected with the transmission gear  31 , which is disengaged from the vortex rod  36 ; or by the rotating and switching of the transferring member  381 , the transmission gear  31  is meshed with the vortex rod  36  and the transmission shaft of the motor  38  is disengaged from the transmission gear  31 . 
     A bottom end of the retractable rod  2  is pivotally connected to the protruding ear  11  disposed on the device body  1 , so that the retractable rod  2  may swing at elevated and depressed angles. A handle  21  is disposed at a top end of the retractable rod  2 . The tube bodies  34  and  35  disposed above the device body  1  are properly fixed to the retractable rod  2  and are pulled out along the retractable rod  2  for connecting to detergent and water. 
     A multi-functional window washing and wiping device is formed by assembling the foregoing components. When using the device, assemble a cleaning tool  4  such as a brush, a sponge, or a piece of cloth on the toothed gear assembly  3 ; input detergent and water via the tube bodies  34  and  35  and release the detergent and water through the cleaning tool  4  below the device body  1 ; and hold the retractable rod  2 , place the device body  1  on a glass window, and move the device body  1  along the glass window. The purpose of washing glass windows in buildings is achieved by rolling the cleaning tool  4  by driving the toothed gear assembly  3  via wheels  37  without the risk of having window washers hang in mid-air. It will be appreciated that the present invention may also be used for cleaning floor. In a similar manner, various cleaning tools  4  may be disposed below the device body  1  and floor cleaning is performed by a user holding the handle  21 .

The rotation of the wheels  37  drives the toothed gear assembly  3 , which drives the cleaning tool  4  to rotate. When the wheels  37  rotate, the vortex rod  36  drives the transmission gear  31 , which drives the two driven gears  32  respectively. The two driven gears  32  then respectively drive the two rotating discs  33 , which drive the cleaning tool  4  disposed on the two rotating discs  33 . Detergent and water are released via the tube bodies  34  and  35  to achieve the purpose of washing glass or cleaning floor. Considering that detergent may cause the wheels  37  to slide when cleaning glass, according to the present invention, by the rotating and switching of the transferring member  381 , a transmission shaft of the motor  38  is pivotally connected with the transmission gear  31 , which is disengaged from the vortex rod  36 . As such, the transmission gear  31  is transmitted by the motor  38  so as to maintain the best cleaning effect. 
     Please refer to  FIG. 5 , showing a view of another preferred embodiment in use according to the present invention. As the figure shows, the present invention may further be provided with a gripper  5 , which may turn about freely. A buckle part  51  is disposed on the gripper  5 , and at least two locking members  52  are disposed at appropriate positions on the gripper  5 . When using the present invention, fix the gripper  5  on a window frame  6  with the locking members  52  and place and position the retractable rod  2  across the buckle part  51 , so that the entire window washing device may be pulled forward and backward and may swing upward and downward with the buckle part  51  as a pivot, which makes it easier and effort-saving to clean glass.
