Abstract

A bed includes a bed frame and a backrest coupled with the bed frame by a plurality of connecting units, each including first and second plate. The first plate is fixedly disposed at a first side of the bed frame and includes one or more slots elongated in the lateral direction of the bed frame. The second plate includes one or more rows of holes, and is fixedly coupled with the first plate by at least one fastener through at least one slot of the first plate and at least one hole of the second plate. Each connecting unit also includes one or more locking nuts fixedly disposed at the second plate, and one or more locking bolts. The one or more locking bolts pass through one or more holes or slots formed in the backrest and fixedly coupled with the one or more locking nuts of the second plate.

Claims
