A lever mechanism system includes push arms pivotably coupled to a vent sash and drive arms pivotably coupled to the push arms. The system includes gears coupled to the drive arms and a locking gear slide coupled with a locking mechanism of the sash. The system includes a handle that rotates approximately 180 degrees in a first direction to pivot the gear slide to move the locking mechanism of the sash to an unlocked position and rotates the gears to extend the drive arms and the push arms such that the sash is pushed to an open position. The handle radially rotates approximately 180 degrees in a second direction to rotate the gears to retract the drive arms and the push arms such that the sash is pulled to a closed position and pivots the gear slide to move the locking mechanism of the sash to a locked position.

A refrigerator-freezer having a first compartment wherein the first compartment is accessible via a rotatable mounted door with the rotatable mounted door being operable to remain disposed within the housing of the refrigerator-freezer during movement thereof. The refrigerator-freezer further includes a second compartment adjacent to the first compartment wherein the second compartment includes a plurality of sealably mounted storage containers slidably mounted within the second compartment. A third compartment is present and is configured to be extendable outward from the housing of the refrigerator-freezer and subsequently be lifted upward via a lifting mechanism. A controller is included to facilitate operation of the refrigerator-freezer. The controller further includes a voice recorder and a printer. The first compartment has disposed therein a plurality of storage bins that are slidably mounted. A battery power supply is included to provide emergency reserve power in the event the conventional AC power supply is disrupted.

A door pop-up system includes a check link, which is rotatably coupled to a body of a vehicle, and a pressure member, which is rotatably arranged inside a door. The check link has a tip portion to enter the inside of the door. The pressure member presses a tip of the check link in a movement direction of the check link in which the check link moves as the door in a closed position is actuated to be opened. The door in a closed position is actuated to be opened by rotation of the pressure member and pressing of the tip of the check link with the pressure member. The pressure member has a pressure surface at which the tip of the check link is pressed. The pressure surface has a restriction surface to restrict displacement of the check link in a height direction.
