Sliding door security assembly

A sliding door security insert assembly installable into an opening made when one sliding door mounted for lateral movement in a door frame including aligned parallel upper and lower tracks and vertical door jambs defining spaced edges of the door frame, the sliding door including spaced upright door stiles, is partially opened to define the opening between one door jamb and a facing one of the door stiles, said assembly comprising:

• a substantially rectangular insert frame having two spaced upright insert frame stiles and spaced upper, lower and intermediate transverse members connected to and extending between said insert frame stiles;
• said insert frame having a height substantially less than that of the sliding door;
• said lower transverse member adapted to be supported on the lower track;
• a height compensating top member coupled to and upwardly extending from, said top member adjustable to vary an overall height of said insert assembly to be substantially equal to that of the sliding door, an upper margin of said top member being adapted to be positioned into the upper track for lateral sliding movement only of said assembly;
• and
• a pair of offset locking pins, one pin of which is threadably attached to and laterally extends from one said insert frame stile and adapted to be inserted into a mating first hole formed into the facing sliding door stile while another pin of said pair of locking pins is threadably attached to and laterally extends from the facing sliding door stile adjacent to the first hole and in alignment with a second hole formed into said insert frame stile, whereby said insert frame and the sliding door are connected together by said locking pins when said insert frame is positioned in the opening and against the sliding door.
