A refrigerator includes: a cabinet; a drawer door assembly including a front panel door part and a drawer part that defines an accommodation space; a rail that movably configured to connect the drawer door assembly to the cabinet and enable the drawer door assembly to insert into and withdraw from the cabinet; a driving device located at the front panel door part and configured to provide power; and an elevation device located in the drawer part and configured to be coupled to the driving device and elevate a portion of the drawer part relative to the front panel door part. The driving device includes: a motor assembly configured to provide driving force; a screw assembly configured to perform an elevation operation based on the driving force; and a lever that connects the screw assembly to the elevation device and that is configured to rotate based on the elevation operation.

A mechanism for vertically sliding a windowed frame in one track alongside a static frame installed in a second track. The mechanism consists of two vertical racks installed on the sliding frame, which engage with two pinions coupled with a joint axle which are installed within the lower horizontal plank of the static frame. Turning the joint axle turns also the pinions which move the frame vertically. There are two options for turning the joint axle. The manual option involves turning a crank, the electrical option involves an electric motor coupled with a gearbox.

The electrical option also includes a control unit for controlling the direction and speed of the sliding, two limit switches for stopping the frame at highest and lowest positions, an electrical overload sensor which detects sudden sliding obstructions and a burglar alarm. The sliding frame also includes four rollers which reduce the sliding friction.

An embodiment integrated operating apparatus for different types of gates includes a driving motor, a main shaft rotatable by the driving motor, a first clutch portion at a first side of the main shaft and configured to selectively transmit power to a first gate of a vehicle, the first clutch portion including a first clutch and a first gear selectively engaged with each other, and a second clutch portion at a second side of the main shaft and configured to selectively transmit power to a second gate of the vehicle, the second clutch portion including a second clutch and a second gear selectively engaged with each other, wherein the first and second gates are configured to be independently operated based on the first clutch portion being in an engaged state or a released state and the second clutch portion being in the engaged state or the released state.

According to particular embodiments, a door operating system comprises: a rotating handle removably coupled to a first gear; the first gear coupled to a second gear; the second gear removably coupled to a worm gear; and the worm gear coupled to a rotating plate. Rotation of the handle rotates the first gear which rotates the second gear which rotates the worm gear which rotates the rotating plate to cause the door to open or close. The first gear is swappable with the second gear to modify a gear ratio of the door operating system.

A multi-axis hinge mechanism for a vehicle door. The multi-axis hinge mechanism moves the vehicle door laterally and vertically by means of multiple axial rotations. An actuator pivots the door hinges attaching the door to the vehicle to move the door away from the vehicle while a set of gears translates the motion of the actuator into a vertical rotation of the door.

One embodiment relates to a door operator including an operator body including a rotatable pinion, an arm connected to the pinion, an inductive sensor mounted adjacent the arm, and a controller in communication with the inductive sensor. The inductive sensor includes an inductor comprising a plurality of nested coils, and each of the coils is curved about the pinion. The controller is configured to provide the inductive sensor with a varying power signal, and the inductive sensor is configured to inductively link the inductor to the arm in response to the varying power signal. The inductive sensor has a characteristic which varies in response to the rotational position of the arm when the inductor is inductively linked with the arm. The controller is further configured receive information relating to the characteristic, and to determine the rotational position of the arm based upon the received information.

Hinged window drive systems and window assemblies incorporating them provide for a combination of powered or motorized operation in addition to manual operation using a hand crank, with the opportunity for a user to switch between motorized operation and manual operation as needed.

An actuator opens and closes a lid on a bulk storage container. The actuator may be activated remotely using a remote control. When actuated, the actuator will lift the lid so that it is clear of the structure, and will then rotate the lid in a horizontal plan about a vertical axis until the lid is rotated to uncover the opening. The axis of rotation is located near the perimeter of the opening, so that very little of the lid remains over the opening when in the open position. To close the lid from the open position, the remote control may then in be used to actuate the closing process. The closing process works in reverse of the opening process. Therefore, during closing, the lid will rotate back to its original orientation over the hole and then lower into the closed position.

Drive assemblies for partition systems may include a motor and a power transmission mechanism operably coupled to a drive shaft of the motor. The power transmission mechanism may include a first bevel gear rotatable by the drive shaft and a second bevel gear positioned for engagement with the first bevel gear. The second bevel gear may include an axis of rotation oriented at least substantially perpendicular to an axis of rotation of the first bevel gear. A disengagement mechanism may be coupled to at least one of the first bevel gear or the second bevel gear and configured to selectively engage and disengage the first bevel gear and the second bevel gear.

A vertical door system includes: a door having a door frame, the door frame having at least one frame section; an operator; two vertical supports configured to: (a) be installable on opposite sides of the door opening and (b) support the vertical door, at least one of the vertical supports having: a guide track on a surface of the vertical support facing toward the door opening; and a drive system having: an elongated threaded rod drivable by the operator via a gearing arranged between the operator and the threaded rod; and one or more blocks, each block comprising a guide track connecting portion that connects to a guide track so the connected block is freely movable along the guide track, each block having a through-bore for accepting the threaded rod so that the block is positioned on the threaded rod and is movable along the threaded rod.
