The invention relates to an extension arm (6) that is arranged on a carrier (4) in such a way that it can pivot about the axis (18) thereof by means of a steering rod (20), and can be blocked in the pivoted position. Said steering rod (20) is arranged on a sleeve (44) that can be pivoted about the extension arm (6), can engage with the extension arm in different rotational angle positions, and can be directly or indirectly blocked on the carrier. According to the invention, a first coupling part (40) fixed to the extension arm (6) co-operates with a second coupling part (42) arranged on the sleeve (44) and acting in the axial direction. Furthermore, the steering rod (20) comprises a supporting element (56) that co-operates with a counterpart (58) arranged on the extension arm (6), in order to displace the second coupling part (42) in the axial direction by means of the steering rod (20). In this way, the extension arm can be pivoted and blocked in a simple manner with one hand.
An extension arm for a free arm parasol, pivotably arranged about its axis on a carrier, the extension arm being pivotable by means of a guide rod and being retainable in the pivoted position, the guide rod being arranged on a sleeve, which is pivotable about the extension arm and being latchable into different rotational angle positions with the extension arm and being retainable directly or indirectly on the carrier, and wherein a first coupling part, is connected fixedly to the extension arm and interacts with a second coupling part which is formed on the sleeve and is operable in the axial direction, said first coupling part and said second coupling part forming a coupling, the guide rod having a supporting element which interacts with a counterpart arranged on the extension arm, in order to displace the second coupling part in the axial direction by means of the guide rod.
