摘要:
A rocker mechanism for rocking furniture, such as rocking chairs, comprises an elongated tubular casing of rectangular cross-section into which is fixedly mounted a stamped member slidable therein. The stamped member includes an elongated oblong base from which perpendicularly extends a short sidewall along the complete periphery thereof. The stamped member further defines a pair of openings and a pair of curved protrusions at each longitudinal end thereof, whereby ball bearings can be received at each such ends between the sidewall of the stamped member and a respective protrusion thereof. The central opening of each ball bearing lies opposite a respective opening defined in the stamped member. Two holes are defined in an aligned relation in the base wall of the stamped member and in one wall of the casing, whereby a pair of screws engaging respective aligned holes of the stamped member and of the casing ensure that the member is fixedly secured to the casing. End caps are snapped onto each end of the casing for completely hiding the stamped member located therein. The rocker mechanism is mounted at the ends thereof to a stationary base of the furniture and to a rocking section thereof by way of pins extending respectively therefrom and engaging ball bearings of the rocker mechanisms.
