An adjustable stroke mechanism has a housing with a central axis and a wall enclosing a cavity. At least one counterweight is movably disposed within the cavity. A mounting assembly is disposed within the cavity. The mounting assembly has a workpiece attachment mechanism. A stroke adjustor couples the at least one counterweight with the mounting assembly. The stroke adjustor enables the counterweight and mounting assembly to move with respect to one another such that a distance between the counterweight and the mounting assembly is variably adjusted which, in turn, variably adjusts a stroke radius of the workpiece attachment mechanism with respect to the central axis of the housing.

A rack assembly for a cooking appliance includes a rack operable between a stowed position and a deployed position. At least one telescoping actuator is operable between a retracted position and an extended position. At least one connector has a first end coupled to a distal end of the telescoping actuator and a second end coupled to the rack. The rack is adjusted from the stowed position to the deployed position as the telescoping actuator adjusts from the retracted position to the extended position.

A transmission element for a controllable air inlet of a motor vehicle and configured to produce a pivoting movement to pivotably mounted closing elements. Each closing element is connected by a link part which is arranged outside the pivot axis, to a corresponding link element of the transmission element (Ü).

A lever device includes a base pedestal, a movable body, a lever, a cam body having a cam groove, a guide pin, and a first biasing member. The lever is configured to swing between a push-down position at which the guide pin is arranged in the upper groove portion and a pull-up position at which the guide pin is arranged in the lower groove portion. The first biasing member has one end connected to a first connector portion provided on the base pedestal; and the other end connected to a second connector portion provided on the cam body, is arranged behind the second lateral shaft when the lever is located at the push-down position, and is arranged in front of the second lateral shaft when the lever is located at the pull-up position.

A driving force transmission device includes an input section and an output section with rotation axes nonparallel to each other to avoid backlash. A driving force transmission device (1) includes a first rotator (2), a second rotator (3), and spheres (5A, 5B, 5C). The first rotator (2) performs one of an input operation and an output operation of a driving force and includes a concave surface (7). The second rotator (3) performs the other of the input operation and the output operation of the driving force and includes a convex surface (13) fitted into the concave surface (7). The spheres (5A, 5B, 5C) are between the concave surface (7) and the convex surface (13). The concave surface (7) has holes (32A, 32B, 32C) in which the respective spheres (5A, 5B, 5C) are received. The convex (13) surface has a groove (29, 30) that receives parts of the spheres (5A, 5B, 5C) protruding from the holes (32A, 32B, 32C).

An elevation device includes a mounting frame, a rotary actuator fixed to the mounting frame, a shaft connected to the rotary actuator and rotatable with respect to the mounting frame, a drive bar slidably connected to the mounting frame, and a connecting member fixed to the shaft. The shaft defines a helical groove in a lateral surface thereof. The drive bar includes a post that is movably fit in the helical groove. The mounting frame, the shaft and the drive bar constitute a conversion mechanism that converts rotation of the shaft into linear motion of the drive bar. The drive bar is slidable with respect to the mounting frame along a direction that is parallel to an axis of rotation of the shaft.

A transmission mechanism applied to a lock and for controlling the lock to switch between an unlocked state and a locked state. The lock includes a first handle set including a first cover plate which includes a first fitting portion. The transmission mechanism includes a transmission element and a moving component. The transmission element is connected to the first handle set in a manner that the transmission element is incapable of moving along a rotating axis and has an abutting portion. The moving component is disposed on the transmission element in a manner that the moving component is capable of moving along the rotating axis and includes a first engaging groove, a second engaging groove and a second fitting portion. When the transmission element is operated to rotate, the abutting portion is capable of switching between the first engaging groove and the second engaging groove.
