ABSTRACT:
A security gate apparatus for attachment across an opening defined by first and second vertical surfaces, including a first gate panel and a second gate panel slidingly connected to the first gate panel so as to permit horizontal extension and retraction of the gate apparatus to a desired horizontal dimension. A first vertical leg is pivotably attached to an outer vertical member of the first gate panel by a first link means and a second vertical leg is pivotably connected to an outer vertical member of the second gate panel by a second link means. The security gate apparatus also includes means for locking the first and second gate panels in the desired horizontal dimension and at least one contact pad on a surface of the first and second vertical legs opposite the outer vertical members of the first and second gate panels, respectively. The security gate apparatus is then installed between the first and second vertical surfaces by pivoting the first and second link means to provide a vertical movement between the first and second gate panels and the first and second vertical legs, as well as a corresponding horizontal movement therebetween, whereby the contact pads frictionally engage the first and second vertical surfaces.
