<p>The invention pertains to a wooden frame structure for a box spring. Two spaced, parallel, upright members form elongated side rails which are intially held together by a base slat extending between the side rails at either end thereof, the base slats being affixed to the bottom of the side railsin recesses therein. Above each base slat, an end slat is installed extending between the side rails, each end slat having a formation such as a tenon formed on either end thereof which engages a corresponding formation such as a mortise formed in each side rail. Normally, at least one center slat, depending on the ultimate frame dimension, lies on its side between the end slats with each end of the center slat lying on a portion of the top of one of the base slats. A plurality of upright cross slats extends between the side rails, and similar to the end slats, each cross slat has a tenon formed in either end thereof which interlockingly engages a corresponding mortise formed in each side rail.</p> |
