Abstract:
A security gate for a passageway comprising:at least three gate panel means;connection means for connecting each of said gate panel means to adjacent gate an panel means for relative telescoping movement with respect thereto, with the gate panel means together moveable between a retracted and extended gate positions to open and close the passageway, wherein the relative movement from the retracted to the extended position is the reverse of the movement from the extended to the retracted position;and control means for controlling the relative movement of said gate panel means between said retracted and extended gate positions so that relative movement is permitted between only two panels at a given time;wherein said control means is constructed and arranged so that said relative movement is progressive as said gate panels are moved between said extended and retracted positions; andwherein said control means comprises:first control member means mounted on at least one of said gate panel means for movement relative thereto between extended and retracted positions;first biasing means for normally urging the first control member means to said extended position;said first control member means comprising first projection means projecting laterally from one face of the gate panel means with the first control member means in its extended position, said first projection means constructed and disposed to be engaged by an adjacent gate panel means as it is moved toward its retracted gate position and to thereby cause the first control member means to move to its retracted position;said first control member means further comprising second projection means projecting laterally from the opposite face of the gate panel means with the first control member means in its extended position, said second projection member means in its extended position, said second projection means being constructed and arranged to abuttably engage an adjacent gate panel means and prevent relative retractive movement therebetween, the second projection means being retracted from said abuttable engagement when the first control member means is moved to its retracted position.
