Abstract

See full text

A bed base having first and second members which are of generally U-shaped configuration so as to slidably telescope together to permit expansion or contraction of the bed base in the lengthwise direction. Locking mechanisms coact between the telescoping legs to lock the bed base in the selected expanded or contracted position. A sheetlike cover is anchored at one end of the bed base and extends along the upper surface thereof towards the other end, at which point an intermediate part of the cover wraps downwardly around a guide drum and then projects reversely toward the other end of the bed base. The lower free end edge of the cover is connected to a compensating mechanism which adjusts the cover length, namely by moving the cover upwardly or downwardly around the guide drum, so that the upper section of the cover always stretches tautly across the upper surface of the bed base irrespective of the adjusted expanded or contracted position.
