Definitions

  • the present invention relates to a safe telescopic mast which does not make noise during operation and require human intervention or any separate power supply.
  • telescopic masts are used in many different fields such as telecommunication, TV outside broadcast vehicles, weather stations, yachts, police vehicles, fire trucks, military vehicles, surveillance points.
  • the said telescopic masts can be extended (extended position) during their use and retracted (retracted position) in cases of non-use and during their transport.
  • Telescopic masts comprise a large number of tubes having diameters different than one another and thus nest into one another and can move relative to one another by means of a drive member such as screw.
  • the drive member extends and retracts the tubes between extended and retracted positions, respectively.
  • Telescopic tube systems comprise lock mechanisms which connect each tube to an adjacent tube in extended and retracted position.
  • a lock system included in each tube ensures that a telescopic mast is kept in an extended position by providing vertical retain against the weight of the said load, when a load is placed on the telescopic mast that reaches the extended position by means of a drive member. Users demand that the said lock mechanisms are automatically driven by means of extension or retraction of the telescopic mast without any human intervention and providing power from the outside.
  • the said lock mechanisms make unwanted noises by a user.
  • Lock mechanisms included in the state of the art fall, make a lot of noise due to the fact that there are a lot of internal clearances during operation and separate off from one another while being in a retracted position.
