TELESCOPIC MAST Russian patent published in 2022 - IPC H01Q1/10 

FIELD: antenna equipment.

SUBSTANCE: invention relates to antenna equipment, in particular, to extending telescopic masts used in wearable radars. The substance of the claimed solution consists in the fact that, in the lock, the locking rod is fixed on a ring configured to rotate on the body of the lock and installed eccentrically relative to the longitudinal axis of the mast elbows, wherein the locking rod constantly enters the groove of the body of the lock and comprises a conical surface, brought into contact with the conical surface of the sleeve of the above-located elbow after the above-located elbow is extended and when the ring is rotated, moving the sleeve upwards until contact with the lock limiter, thereby ensuring that the elbows are mutually fixed; wherein the selected angle of the conical surfaces of the locking rod and the sleeve ensures that the connection self-brakes, and the locking rod has an operating range for guaranteed selection of the play between the mast elbows.

EFFECT: simplification and minimisation of the size of the lock and elimination of the possibility of the lock hooking on various surrounding objects, creation of a lock design allowing for work therewith without removing mittens; and possibility of play-free mutual fixation of the elbows.
