Rocking chair

Rocking chairs are an enduringly popular item of living room furniture. Rocking chairs have been used for centuries as soothing furnishings in the homes of many people. The comfortable oscillating motion of a rocking chair has been a comfort to many people through the years. One of the coziest pieces of furniture, the rocking chair is a perennial favorite with babies, kids, and adults. A rocking chair is a chair on rockers that can be moved backwards and forwards. Regular rocking chairs are commonly made of wooden material, and the related parts are fixedly connected to one another by fastening means or joints. A rocking chair is comprised of a chair supported on a rocker base. The rocker base comprises two concave curved rocker bars on opposite sides of the chair. The curved configuration of the rocker bars allows the chair to rock forward and backward. A typical rocking chair includes a body supporting structure that is mounted on a chair base by a rocking assembly. Locking mechanism comes in two flavours: manually operated and automatic. Generally, the chair comprises a fixed base, a seat rockably mounted to the base, and a locking mechanism mounting to the chair for selectively immobilizing the seat relatively to the base. One locking mechanism comprises two components, namely a rack element including a plurality of fingers in a spaced apart relationship, and a pin element that can fit between selected fingers of the rack. The rack element is mounted to the body-supporting portion of the chair while the pin is mounted to the chair base portion. The rack element is also provided with a linkage that allows moving the rack in and out of engagement with the pin. Such locking mechanisms provides stability to the chair, since the user will typically have his or her feet off the floor when the ottoman is in the extended position, and rocking of the chair under these circumstances may result in discomfort to the user. To provide a rocking motion, a fixed-base chair structure includes a flexible coupling member that is located between the base portion and the seat portion. Fixed-base rocking chairs are typically less bulky than curved rail rocking chairs. As a result, fixed-base rocking chairs are more compact and may be used with a table in a more practical fashion. In addition, they do not require a smooth, flat surface. Collapsible rocking chairs comprises two pairs of rods crossing but not jointed to each other. Cross bars having opposite ends pivoted to the rods respectively are arranged above and below the crossing point of the rods. Swinging one of the rods by the weight of the person sitting on the chair causes the other rod to move therewith and back-and-forth swinging of the rods leads to rocking motion of the chair. Rocking reclining chairs are typically constructed to provide a locking mechanism to prevent rocking of the chair when the chair's ottoman is extended.
