An adjustable safety block assembly is disclosed which can be used to traverse an opening for a sliding door in order to block it. The assembly consists of inner and outer tubular members which can be telescoped together. One of the tubular members has a series of axially extending rows of holes spaced at even intervals, and staggered around the radius of the two. The other tubular member has groups of evenly axially spaced circumferentially distributed holes radially arranged. The tubular members may be telescoped until the desired length is achieved, and then holes of the inner and outer tubular members aligned so that locking means can be inserted through the aligned holes to fix the tubular members in relative position, to form a rigid bar. Thus, the safety block is easily adjustable to accommodate any patio door widths, and may be disassembled for storage and travel.

An adjustable safety block assembly for traversing an opening for a sliding door, comprising: a first tubular member having a first series of circumferentially distributed axially extending rows of holes circumscribing its tube wall, the hole of the first series being spaced in uniform intervals from axially adjacent holes and being axially staggered in uniform intervals relative to circumferentially adjacent holes; a second tubular member engaging the first tubular member in sliding telescopic relation and having a second series of circumferentially evenly distributed holes, the holes of the second series being axially staggered relative to circumferentially adjacent holes in uniform intervals equal to the fraction obtained by dividing the length of the interval of axial staggering of holes in the first series by the number of holes in the second series; locking means inserted through aligned holes of the first and second series respectively for retaining the tubular members in mutually fixed relation to form a rigid bar; and caps mounted on opposite ends of the rigid bar, each cap being provided with a groove extending axially relative to the tubular members for engaging a lip of a runner of a sliding door for limiting lateral displacement of the safety block from the opening for the sliding door.
