A furniture member includes a base assembly, a frame assembly, a legrest mechanism, a support rod, and a sync mechanism. The frame assembly is movable relative to the base assembly among an upright position, a partially reclined position, and a fully reclined position. The legrest mechanism is movable relative to the frame assembly between a retracted position and a fully extended position. The support rod is supported by the frame assembly. The sync mechanism is coupled to and supported by the support rod. The sync mechanism is configured to prevent the frame assembly from moving from the upright position to the partially reclined position until the legrest mechanism reaches the fully extended position.

A torque drive transmission, having at least two counter-rotating cams bearing-mounted within a housing about a rotational axis. The counter-rotating cams are operative to: (i) convert a linear input to a rotary output, and (ii) drive a pair of coaxial drive shafts in opposite directions along the rotational axis. Furthermore, each counter-rotating cam defines a cam profile surface having drive and follower surfaces defining angles α and β respectively. The angles α and β are unequal to drive each cam and respective output drive shaft in an opposite rotational direction. As such, the cams may be driven in opposite directions irrespective the initial rotational position of the linear input, i.e., relative to each counter-rotating cam.

A drive transmission has two counter-rotating cams bearing-mounted within a housing about a rotational axis. The counter-rotating cams have asymmetrical lobe profiles which are operative to drive a corresponding pair of coaxial drive shafts in opposite directions along the rotational axis. The asymmetry of the lobe profiles prevents the cams from locking when the lobe apexes pass the top and bottom dead center positions relative to the follower or drive pins.

Disclosed is a continuously variable transmission which can simplify a structure and contribute to miniaturization of a device. A continuously variable transmission including a first disk unit with a first guide slot, a second disk unit with a second guide slot which the first guide slot crosses, and a guide member provided to move along the first guide slot and the second guide slot in response to relative rotation of the second disk unit to the first disk unit, includes: a rotation driving unit rotating any one of the first disk unit and the second disk unit with respect to the other one, wherein the rotation driving unit includes a barrel cam member, a linear movement member linearly moving in response to rotation of the barrel cam member, a driving cam member linearly moving together with the linear movement member, and a driven cam member rotatably connected integrally with any one of the first disk unit and the second disk unit and selectively rotating in response to the linear movement of the driving cam member.
