Abstract:
An angularly adjustable releasably lockable joint mechanism for rigidly joining first and second parts at a selected orientation, said mechanism comprising:a first member having a plurality of patterns of spaced apart protuberances covering at least a part of a surface of the first member, each of the plurality of patterns of the spaced apart protuberances forming a concavity therebetween; a second member having a disengageable actuator, the disengageable actuator having at least one tip and being operative to advance the at least one tip to lock up with the first member by penetrating at least one concavity of the first member or to retract the at least one tip to disengage from the first member, the actuator being connected with the second part; and a housing which retracts the at least one tip with respect to the first member such that the first and second members are disengaged and the first and second parts change relative orientation when the at least one tip is retracted, wherein the protuberances, the actuator tip, and the patterns of the protuberances are dimensioned so that the at least one tip penetrates the concavity of each pattern and simultaneously contacts the protuberances of the pattern, whereby the tip and the pattern of protuberances lock together, and wherein one of the at least one tip is spaced apart from the surface of the first member at one concavity in both an engaged position and a disengaged position.
