An overhead door system is disclosed, which includes a first track and a second track mounted on opposite sides of an opening. Each track has a vertical portion, a transition portion, and a horizontal portion, with the transition portion being between the vertical portion and the horizontal portion. An overhead door engages the first and second tracks on opposite sides of the overhead door and is movable along the first and second tracks between a closed, vertical position and a raised, horizontal position. A motor unit has a motor that is mounted above the horizontal portions of the first and second tracks. A rail is parallel to and disposed between the horizontal portions of the first and second tracks. The rail carries a carriage configured to move in a first direction to raise the overhead door and in a second, opposite direction to lower the overhead door. A connecting member is pivotally attached at one end near a top edge of the overhead door and attached at an opposite end to the carriage. A one-way bearing is disposed between the motor and the carriage. The motor, as it rotates in a first rotational direction, applies force to the carriage to move the carriage in the first direction to raise the overhead door. Nevertheless, owing to the one-way bearing, the motor, as it rotates in a second, opposite rotational direction, does not apply force to the carriage to move the carriage in the second direction to lower the overhead door. A kit to retrofit an overhead door system with a one-way bearing is also disclosed.

A mechanism for opening and closing an overhead door includes a drive loop coupled to the overhead door, a motor with a drive shaft and a drive wheel for driving the drive loop. A one-way bearing couples the drive shaft to the drive wheel, which one-way bearing is configured to transmit torque from the motor to the drive wheel, as the motor rotates the drive shaft in a first rotational direction to raise the overhead door, and configured so that torque is not transmitted to the drive wheel as the motor rotates the drive shaft in a second rotational direction opposite the first rotational direction. As a result, the motor applies torque through the one-way bearing to raise the overhead door and to support the weight of the overhead door while lowering the overhead door.

A vertical pivoting gate operator for positioning a gate between an open position and a closed position is provided. The gate operator includes a motor drive assembly including a motor and a linkage assembly mechanically connecting a motor output to the gate such that in response to actuation of the motor, the linkage assembly transmits an opening force to positioning the gate toward the open position, and a closing force, for positioning the gate toward the closed position. A counterbalance assembly including a biasing member is operable to release stored energy against an input link to rotate a gate arm shaft so as to urge the gate toward the open position and to increase stored energy in response to rotation of the gate traveling toward the closed position to act against the gate as it approaches the closed position.

A hinged-panel opening and closing system includes: an anchor designed to be located on a hinged panel; a gear motor designed to be located on a supporting structure; and a movement-enabling component capable of angularly displacing the hinged panel relative to a receiving structure. The movement-enabling component includes: (a) a movement-enabling shaft located on the supporting structure and, at one shaft end, coupled to the gear motor; (b) a spindle located on supporting structure and coupled to the movement-enabling shaft; and (c) a linear element attaching, at a first end, to the spindle and attaching, at a second end, to the anchor such that said linear element extends between the spindle and the anchor.

Disclosed are a gate mechanism and a cash recycling and handling device. The gate mechanism includes a frame with an opening, a driving door and a driven door both of which are movably connected to the frame, where the driving door can be located at a first position and a second position, and the driven door can be located at a third position and a fourth position; when the driving door is located at the first position and the driven door is located at the third position, the driving door and the driven door jointly close the opening; when the driving door is located at the second position and the driven door is located at the fourth position, the driving door and the driven door jointly open the opening, and the driven door at the fourth position, the driving door at the second position and a panel are sequentially stacked.

A door opening and closing apparatus includes: a body defining an opening and an interior space, the opening being open toward the outside of a vehicle body and the interior space defined inside the vehicle body so as to be connected to the opening; a door configured to open and close the opening; a guide part disposed in the interior space and guiding the door such that the door moves in a first direction and a direction opposite to the first direction, the first direction being a direction from the outside of the vehicle body to the inside of the vehicle body; and a transport part disposed in the interior space and that moves the door in a second direction and a direction opposite to the second direction.

A gearing device for discontinuously moving at least two elements, in particular barrier elements of a passageway device, having a drive axis, a first active axis of rotation, formed for a torque-transmitting operative connection with the first element, in particular barrier element, a first non-uniformly translating gearing stage between the drive axis and the first active axis of rotation, a second active axis of rotation formed for a torque-transmitting operative connection with the second element, in particular barrier element, a second non-uniformly translating gearing stage between the drive axis and the second active axis of rotation.

A panel system for closing and opening a merchandise space of a refrigerated cabinet includes multiple movable panels. Each panel is movable between an open position and a closed position. Two of the panel are connected to form a pair of panels. A return mechanism is arranged above the pair of panels and a pulling mechanism is guided over the deflection mechanism and connects the two panels in the pair. Each panel of the pair is disposed with respect to the deflection mechanism so that a movement of one panel in a first movement direction effectuates a movement of the second panel in a second movement direction. A refrigerated cabinet includes such a panel system.

A system for controlling one or more motorized windows. The motorized windows each have a processor, a network device and wireless transmitters enabling connection via a network. The network is controlled by one or more mobile devices which receive user input. The mobile devices wirelessly connect to a local area network (LAN) via a hub. One or more hubs are connected via the LAN. The motorized windows are networked via a personal area network (PAN). The hubs convert the LAN protocol to the PAN protocol. Sensors send sensor data along with real time weather data to the processor. The processor uses this sensor data to update charts and schedules in memory, then sends commands to the controller based on these updated charts and schedules according to user defined and factory set parameters. The system includes both local and cloud-based control.

A lock device for locking the sliding door comprises a first lock portion and a transmission portion. The transmission portion may move along relative to the first lock portion a predetermined path, so that the transmission portion may bring the sliding door to move along the predetermined path to open or close the sliding door. The transmission portion has a plurality of successively arranged mating portions for locking with the first lock portion. The first lock portion has a first position in which the first lock portion is locked with the transmission portion and a second position in which the first lock portion is released from the transmission portion. The transmission portion may be locked in different positions along the predetermined path by matching the first lock portion 110 with different mating portions, so that the sliding door can be locked in different positions.
