Bring Back The "Murphy Bed"!
"A Murphy Bed is a bed that folds down from a wall. William L. Murphy applied for a patent for this idea April 1st, 1916 and was granted Design Patent D49,273 on June 27, 1916. Murphy started the Murphy Wall Bed Company and began production in San Francisco. In January 1990, the company changed its name to the "Murphy Bed Co. Inc." A Murphy bed is used for space-saving purposes, much like a trundle bed is. These beds make appearances in movies as they lend themselves to slapstick humor in which people are trapped when the bed folds into the upright position, carrying the person on the bed inside. In Mel Brooks' Silent Movie, a hotel's neon sign advertises "Murphy Beds -- Charming to the Unsophisticated". In 1989 an appellate court held that the term "Murphy bed" is no longer entitled to trademark protection because a substantial majority of the public perceive the term as a generic term for a bed that folds into a wall rather than the specific model made by the Murphy Bed Co."
I am thrilled, I actually had a reason to use Wikepedia! They even list retailers that sell Murphy Beds.
