Preventing toppling of cabinets or other furniture

Claim 1

An article of furniture having a plurality of internal units mounted so as to be slidable out of the article, and a safety device restricting the total number of said units slidable out concurrently yet permitting the sliding out of any chosen one of said units while so restricting the total number, said safety device comprising: a guide adapted to be positioned on the article so as not to obstruct sliding out of said units, and a plurality of blocking elements slidably mounted on the guide and projecting from the guide to block the sliding out of said units, the blocking elements being displaceable relative to each other lengthwise along the guide, displacement of at least one blocking element relative to the remining blocking elements creating a gap between successive blocking elements to permit the sliding out of a chosen unit through said gap, the length of said guide available to the blocking elements and the number and total length of said blocking elements thereon being such that said blocking elements occupy less than the total length of the guide available to the blocking elements and leave a remaining free length which is sufficiently great such that when none of said slidable units has been slid out, any blocking elements in the path of any one of the slidable units can be displaced far enough along the guide to create a gap for that unit to be slid out, said free length of the guide being sufficiently limited to restrict the creation of gaps between successive blocking elements and thereby restrict the number of said slidable units which can be slid out concurrently.
