Abstract:
The invention relates to a drive device (20) for entrance and exit devices for public transportation vehicles, comprising a drive unit (22) that is arranged in and drives a rotary column (24) rotating about a rotational axis Z-Z during opening and closing operations, said column opening and closing the entrance and exit device. The drive unit (22) is held on the vehicle via a retaining component (40). The retaining component (40) acts as counter bearing for a torque of the drive unit (22). Between the drive unit (22) and the retaining component (40), a coupling device (72) is arranged, which enables a rotation of the drive unit (22) about the rotational axis Z-Z when a threshold value of the torque acting upon the drive unit is exceeded. Between the coupling device (72) and the retaining component (40), a bearing is provided, which enables a tumbling motion of the rotary column (24) with the coupling device (72) and prevents a rotation about the rotational axis Z-Z.
Abstract:
A door operator for selectively opening and closing a side hinge door. The door operator may include a motor with a drive shaft, an operator arm assembly, a door position sensor, and a controller. The operator arm assembly may include an output shaft operatively coupled to the drive shaft, an operator arm, and a clutch assembly mounted to the output shaft. The door position sensor, which may be electro-magnetic, signals the controller when the door is not closed. If the door has been manually pushed open, the controller signals the motor to rotate the drive shaft in the closing direction. In automatic mode, the output shaft and the operator arm are operatively engaged, but manual force to open the door overcomes static friction between the operator arm and friction discs in the clutch assembly, operatively disengaging the operator arm and output shaft until the manual force is removed.

Abstract:
A driver assistance system is provided for a motor vehicle, which has a first ascertainment device, the first ascertainment device implemented to ascertain at least one parameter that characterizes a possible fatigue of a current driver of the motor vehicle. In addition, the driver assistance system has a second ascertainment device, which is implemented to ascertain a degree of fatigue of the driver based on the at least one ascertained parameter. In addition, the driver assistance system has an opening device, which is implemented to at least partially open at least one window of the motor vehicle if the ascertained degree of fatigue of the driver exceeds a first predetermined threshold value.
Abstract:
A refrigerator including a body, a door movably coupled to the body, a gasket installed at a rear surface of the door to establish a gasket seal between the door and the body when the door is in a closed position, a first mount provided at a first location of the door located adjacent to a left edge portion of the door, a second mount provided at a second location of the door located adjacent to a right edge portion of the door, and a door opening device to cause the gasket seal to break between the door and the body, the door opening device including a pivoting member mounted to the door, first and second operating portions and a first push unit mounted to a first mount to press against the body when being pressed by the first operating portion of the pivoting member.
Abstract:
An opening and closing device for an automobile trunk lid is capable of producing an optimum pop-up amount by mounting an elastic springing means, which is used to hold a trunk lid in a popped-up state in cooperation with torsion bars when the trunk lid is unlocked, in a link mechanism part that transmits the torsional torque of the torsion bars to the hinge arm of the trunk lid.
Abstract:
A door closer that integrally incorporates a door-opening-assistance device, and that therefore eliminates the need for unnecessary troublesome adjustment between parts, and whose number of parts is reduced, making said door closer compact. The door closer 1 includes a closer 1a that includes a pinion 5 that rotates in the forward and reverse directions when the door is opened or closed, respectively. A cylinder 9 is meshed with the pinion 5 and moves forward and backward. A closing spring 14 energizes the door in the closing direction via the cylinder 9 and the pinion 5. A opening-assistance device 1b that includes an opening spring 22 that stores an opening force in the door-opening direction due to the movement of the cylinder 9 when the door is opened. Locking mechanisms 27, 28, and 29, that—when the door is opened—lock the opening spring 22 under an opening-force-storing condition. An unlocking mechanisms 23 and 24 that—when the door is closed—unlock the locking mechanisms. The closer 1a and the door-opening-assistance device 1b are inside the same case 6 and interlinked by the opening of the door.
Abstract:
A vehicle closure hinge includes a mount having a pivot axis flange, a pivot link, a pivot coupling the pivot link to the pivot axis flange and a spring formed by a laterally coiled strand extending from a first coil end to a second coil end in a direction substantially perpendicular to the plane of displacement about the pivot axis. The coil size, the strand size and the number of coils can be varied as desired to vary the spring biasing force exerted against the vehicle closure without varying other components of the hinge. The hinge parts may be designed with various configurations including simple pivoting links or a four bar linkage. A strand end of the coil spring extends along the direction of the coil to a position at a first coil end to maintain biasing force near the plane of displacement about the pivot axis.
Abstract:
A refrigerator including a door opening device mounted in a grip part defined in any one of an upper surface and lower surface of a door and a side surface of the door opposite to a hinge shaft of the door. The door opening device is covered with a shield provided at a front surface of the door.
Abstract:
A refrigerator and/or freezer with an appliance carcass, can be closed by at least one door, and a powered door operating device for automatically operating the door. The door operating device has drives both automatically opening and closing the door.
