<p>An adjustable bed frame has a pair of end rails adjustably interfitted to support varying widths of bedding thereon. The rail pairs are interfitted channel-shaped rail sections. A fastenerless latch mechanism for retaining the end rails in pre-determined relation has a body portion rotatably mounted adjacent the outside surface of the back wall of the outer rail section and has opposite, transversely-turned arms positioned in overlying relation to the side walls of the outer rail. The latch arms have arcuate, inwardly-extended fingers. A plurality of pairs of openings on the inner rail are positioned to permit entrance of the latch fingers therethrough upon rotation of the latch member to lock the rail sections at an adjusted position. The fingers present convex or angled camming surfaces to the side walls of the inner rail sections so that forces tending to move the rail sections telescopically in either direction will present the side walls of the inner section against a camming finger surface, thus tending to hold the latch member in a latched position.</p> |
