Abstract

A stabilized suspended platform comprises a platform suspended from a support unit by a cable. The support unit includes traction means for releasing or pulling part of the cable so as to set the platform at a desired height, and the platform includes propellers for fine movements or stabilizing the platform in space, further including remote control system with means for communicating with the support unit and the platform for controlling the spatial location of the platform. The support means may further include means for moving the platform laterally.

1 . A stabilized suspended platform comprising a platform suspended from a support unit by cable means, wherein the support unit includes traction means for releasing or pulling part of the cable means so as to set the platform at a desired height, and the platform further includes propeller means for fine movements or stabilizing the platform in space, further including remote control means with means for communicating with the support unit and the platform means for controlling the spatial location of the platform. 
   
   
       2 . The stabilized suspended platform according to  claim 1 , wherein the support means further include means for moving the platform laterally. 
   
   
       3 . The stabilized suspended platform according to  claim 1  or  2 , wherein the platform further includes clasping means for attaching work accessories. 
   
   
       4 . The stabilized suspended platform according to  claim 3 , wherein the work accessories include a device for cleaning windows and building facades using brushes or sand blasting. 
   
   
       5 . The stabilized suspended platform according to  claim 3 , wherein the work accessories include means for cleaning by pressured sand. 
   
   
       6 . The stabilized suspended platform according to  claim 1  or  2 , wherein the cable means further include conduits for electric power, communications, water, pneumatic pressure and/or detergents. 
   
   
       7 . The stabilized suspended platform according to  claim 1  or  2 , further including closed loop servo means for keeping the platform at a desired location in space, wherein the servo means include input means for receiving a desired location command, sensor means for detecting deviations from the desired location and propeller means for exerting a force to move the platform to the desired location. 
   
   
       8 . The stabilized suspended platform according to  claim 7 , further including means for receiving the desired location command from a remote location. 
   
   
       9 . The stabilized suspended platform according to  claim 7  or  8 , further including means for controlling the propeller power under servo loop control. 
   
   
       10 . The stabilized suspended platform according to  claim 7  or  8 , further including means for controlling the propeller power and orientation under servo loop control. 
   
   
       11 . The stabilized suspended platform according to  claim 1  or  2 , further including sensor means for measuring the actual location of the platform and means for controlling the propeller power and orientation under servo loop control so as to keep the platform at a desired location. 
   
   
       12 . The stabilized suspended platform according to  claim 11 , wherein the sensor means include video, gyroscope inertial sensors, radar, ultrasound, infrared and/or other sensors. 
   
   
       13 . A stabilized suspended platform substantially as detailed in the present disclosure with reference to the drawings.
